//============================================================

This document is a reference manual for all the scripting commands and
functions available in current Hercules GIT. It is not a simple tutorial.
When people tell you to "Read The F***ing Manual", they mean this.

The information was mostly acquired through looking up how things actually
work in the source code of the server, which was written by many people
over time, and lots of them don't speak English and never left any notes -
or are otherwise not available for comments. As such, anything written in
here might not be correct, it is only correct to the best of our
knowledge, which is limited.

This is not a place to teach you basic programming. This document will not
teach you basic programming by itself. It's more of a reference for those
who have at least a vague idea of what they want to do and want to know
what tools they have available to do it. We've tried to keep it as simple
as feasible, but if you don't understand it, getting a clear book on
programming in general will help better than yelling around the forum for
help.

A little learning never caused anyone's head to explode.

Structure
---------

The commands and functions are listed in no particular order:

*Name of the command and how to call it.

Descriptive text

    Small example if possible. Will usually be incomplete, it's there just
    to give you an idea of how it works in practice.

To find a specific command, use Ctrl+F, (or whatever keys call up a search
function in whatever you're reading this with) put an * followed by the
command name, and it should find the command description for you.

If you find anything omitted, please tell us. :)

Syntax
------

Throughout this document, wherever a command wants an argument, it is
given in <angle brackets>. This doesn't mean you should type the angle
brackets. :) If an argument of a command is optional, it is given in
{curly brackets}. You've doubtlessly seen this convention somewhere, if
you didn't, get used to it, that's how big boys do it. If a command can
optionally take an unspecified number of arguments, you'll see a list like
this:

command(<argument>{, <argument>...<argument>})

This still means they will want to be separated by commas.

Where a command wants a string, it will be given in "quotes", if it's a
number, it will be given without them. Normally, you can put an
expression, like a bunch of functions or operators returning a value, in
(round brackets) instead of most numbers. Round brackets will not always
be required, but they're often a good idea.

Wherever you refer to a map, use 'mapname' instead of 'mapname.gat'.


Script loading structure
------------------------

Scripts are loaded by the map server as referenced in the
'npc/(pre-)re/scripts_main.conf' configuration file.

The file contains a list of scripts to be loaded (or other configuration files
to be parsed, through the @include directive), in the following format:

npc_global_list: (
    "npc/path/to/the/script/to/load.txt",
    "npc/other/file.txt",
@include "npc/other_configuration_file.conf"
)

Any script will only get loaded once even if specified twice, to prevent
possible errors.

It's possible to specify scripts to exclude from loading, by inserting them
(using the same syntax) in the list available in npc/scripts_removed.conf:

npc_removed_list: (
    "npc/path/to/the/file/to/skip.txt",
)

Script file format
------------------

Whenever '//' is encountered in a line upon reading, everything beyond
this on that line is considered to be a comment and is ignored. This works
wherever you place it.

// This line will be ignored when processing the script.

Block comments can also be used, where you can place /* and */ between any
text you wish Hercules to ignore.

Example:
/* This text,
 * no matter which new line you start
 * is ignored, until the following
 * symbol is encountered: */

The asterisks (*) in front of each line is a personal preference, and is
not required.

Upon loading all the files, the server will execute all the top-level
commands in them. No variables exist yet at this point, no commands can be
called other than those given in this section. These commands set up the
basic server script structure - create NPC objects, spawn monster objects,
set map flags, etc. No code is actually executed at this point except
them. The top-level commands the scripting are pretty confusing, since
they aren't structured like you would expect commands, command name first,
but rather, normally start with a map name.

What's more confusing about the top-level commands is that most of them
use a tab symbol to divide their arguments.

To prevent problems and confusion, the tab symbols are written as '%TAB%'
or '<TAB>' throughout this document, even though this makes the text a bit
less readable. Using an invisible symbol to denote arguments is one of the
bad things about this language, but we're stuck with it for now. :)

Here is a list of valid top-level commands:

** Set a map flag:

<map name>%TAB%mapflag%TAB%<flag>

This will, upon loading, set a specified map flag on a map you like. These
are normally in files inside 'npc/mapflag' and are loaded first, so by the
time the server's up, all the maps have the flags they should have. Map
flags determine the behavior of the map regarding various common problems,
for a better explanation, see 'setmapflag'.

** Create a permanent monster spawn:

<map name>,<x>,<y>,<xs>,<ys>%TAB%monster%TAB%<monster name>%TAB%<mob id>,<amount>,<delay1>,<delay2>,<event>{,<mob size>,<mob ai>}

Map name is the name of the map the monsters will spawn on. X,Y are the
coordinates where the mob should spawn. If X's and Y's are non-zero, they
specify the 'radius' of a spawn-rectangle area centered at x,y. Putting
zeros instead of these coordinates will spawn the monsters randomly. Note
this is only the initial spawn zone, as mobs random-walk, they are free to
move away from their specified spawn region.

Monster name is the name the monsters will have on screen, and has no
relation whatsoever to their names anywhere else. It's the mob id that
counts, which identifies monster record in 'mob_db.txt' database of
monsters. If the mob name is given as "--ja--", the 'japanese name' field
from the monster database is used, (which, in Hercules, actually contains
an English name) if it's "--en--", it's the 'english name' from the
monster database (which contains an uppercase name used to summon the
monster with a GM command).

Amount is the amount of monsters that will be spawned when this command is
executed, it is affected by spawn rates in 'conf/map/battle.conf'.

Delay1 and delay2 control monster respawn delays - the first one is the
fixed base respawn time, and the second is random variance on top of the
base time. Both values are given in milliseconds (1000 = 1 second). Note
that the server also enforces a minimum respawn delay of 5 seconds.

You can specify a custom level to use for the mob different from the one
of the database by adjoining the level after the name with a comma. eg:
"Poring,50" for a name will spawn a monster with name Poring and level 50.

Event is a script event to be executed when the mob is killed. The event
must be in the form "NPCName::OnEventName" to execute, and the event name
label should start with "On". As with all events, if the NPC is an
on-touch NPC, the player who triggers the script must be within 'trigger'
range for the event to work.

There are two optional fields for monster size and AI. Size can be 0
(medium), 1 (small), or 2 (big). AI can be 0 (default), 1
(attack/friendly), 2 (sphere), 3 (flora), or 4 (zanzou).

Alternately, a monster spawned using 'boss_monster' instead of 'monster' is able to be
detected on the map with the SC_CASH_BOSS_ALARM status (used by Convex Mirror, item ID# 12214).
A monster spawned using 'miniboss_monster' is spawn monster as mini boss view.

** NPC names

/!\ WARNING: this applies to warps, NPCs, duplicates and shops /!\

NPC names are kinda special and are formatted this way:

<Display name>{::<Unique name>}

All NPCs need to have a unique name that is used for identification
purposes. When you have to identify a NPC by it's name, you should use
<Unique name>. If <Unique name> is not provided, use <Display name>
instead.

The client has a special feature when displaying names: if the display
name contains a '#' character, it hides that part of the name.
Ex: if your NPC is named 'Hunter#hunter1', it will be displayed as 'Hunter'

<Display name> must be at most 24 characters in length.
<Unique name> must be at most 24 characters in length.

** Define a warp point

<from map name>,<fromX>,<fromY>{,<facing>}%TAB%warp%TAB%<warp name>%TAB%<spanx>,<spany>,<to map name>,<toX>,<toY>

This will define a warp NPC that will warp a player between maps, and
while most arguments of that are obvious, some deserve special mention.

SpanX and SpanY will make the warp sensitive to a character who didn't
step directly on it, but walked into a zone which is centered on the warp
from coordinates and is SpanX in each direction across the X axis and
SpanY in each direction across the Y axis.

Warp NPC objects also have a name, because you can use it to refer to them
later with 'enablenpc'/'disablenpc'.

Facing of a warp object is irrelevant, it is not used in the code and all
current scripts have a zero in there.

** Define an NPC object.

<map name>,<x>,<y>,<facing>%TAB%script%TAB%<NPC Name>%TAB%<sprite>,{<code>}
<map name>,<x>,<y>,<facing>%TAB%script%TAB%<NPC Name>%TAB%<sprite>,<triggerX>,<triggerY>,{<code>}

This will place an NPC object on a specified map at the specified
location, and is a top-level command you will use the most in your custom
scripting. The NPCs are triggered by clicking on them, and/or by walking
in their trigger area, if defined. See that below.

Facing is a direction the NPC sprite will face in. Not all NPC sprites
have different images depending on the direction you look from, so for
some facing will be meaningless. Facings are counted counterclockwise in
increments of 45 degrees, where 0 means facing towards the top of the map.
(So to turn the sprite towards the bottom of the map, you use facing 4,
and to make it look southeast it's facing 5.)

Sprite is the sprite identifier used to display this particular NPC. For a
full list of sprite numbers see http://nn.ai4rei.net/dev/npclist/ as
well as doc/constants.md.
You may also use a monster's ID constant instead to display a monster sprite
for this NPC, in npcs that have view ids of mobs it's encouraged to use
OnTouch events with a 2,2 range and with an 'end' after the header to avoid
bugs (for more info on why see npc_click@map/npc.c). It is possible to use a job
sprite as well, but you must first define it as a monster sprite in 'mob_avail.txt',
a full description on how to do this is not in the scope of this manual.
A 'FAKE_NPC' sprite will make the NPC invisible (and unclickable).
A 'HIDDEN_NPC' sprite will make an NPC which does not have a sprite, but is
still clickable, which is useful if you want to make a clickable object of
the 3D terrain.

TriggerX and triggerY, if given, will define an area, centered on NPC and
spanning triggerX cells in every direction across X and triggerY in every
direction across Y. Walking into that area will trigger the NPC. If no
'OnTouch:' special label is present in the NPC code, the execution will
start from the beginning of the script, otherwise, it will start from the
'OnTouch:' label. Monsters can also trigger the NPC, though the label
'OnTouchNPC:' is used in this case, and using mobattached() will return
monster GID. If player left the area will trigger the label 'OnUnTouch'.

The code part is the script code that will execute whenever the NPC is
triggered. It may contain commands and function calls, descriptions of
which compose most of this document. It has to be in curly brackets,
unlike elsewhere where we use curly brackets, these do NOT signify an
optional parameter.

** Define a 'floating' NPC object.

-%TAB%script%TAB%<NPC Name>%TAB%FAKE_NPC,{<code>}

This will define an NPC object not triggerable by normal means. This would
normally mean it's pointless since it can't do anything, but there are
exceptions, mostly related to running scripts at specified time, which is
what these floating NPC objects are for. More on that below.

** Define a shop/cashshop NPC.

-%TAB%shop%TAB%<NPC Name>%TAB%<sprite>,<itemid>:<price>{,<itemid>:<price>...}
<map name>,<x>,<y>,<facing>%TAB%shop%TAB%<NPC Name>%TAB%<sprite>,<itemid>:<price>{,<itemid>:<price>...}

This will define a shop NPC, which, when triggered (which can only be done
by clicking) will cause a shop window to come up. No code whatsoever runs
in shop NPCs and you can't change the prices otherwise than by editing the
script itself (no variables even exist at this point of scripting, so
don't even bother trying to use them).

The item id is the number of item in the 'item_db.txt' database. If Price
is set to -1, the 'buy price' given in the item database will be used.
Otherwise, the price you gave will be used for this item, which is how you
create differing prices for items in different shops.

You can alternatively use "cashshop" in place of "shop" to use the Cash
Shop interface, allowing you to buy items with special points (Currently
stored as account vars in #CASHPOINTS and #KAFRAPOINTS). This
type of shop will not allow you to sell items at it, you may only purchase
items here. The layout used to define sale items still count, and
"<price>" refers to how many points will be spent purchasing the them.

** Define a trader NPC
<map name>,<x>,<y>,<facing>%TAB%trader%TAB%<NPC Name>%TAB%<sprite>,{<code>}
-%TAB%trader%TAB%<NPC Name>%TAB%FAKE_NPC,{<code>}

All the standards that are valid to script objects are also valid for trader objects
(see ** Define an NPC object for more information).
This will define a trader NPC, which can cause a shop, cashshop or market window
to come up when clicked or called by other means. Unlike shop/cashshop NPCs this
type will run a code and can change the items that are being sold over time without
other NPC objects.
The types that a trader object can have are the following:
- NST_ZENY	(0) Normal Zeny Shop (shop)
- NST_CASH	(1) Normal Cash Shop (cashshop)
- NST_MARKET	(2) Normal NPC Market Shop (where items have limited availability
		    and need to be refurbished)
- NST_CUSTOM	(3) Custom Shop (any currency, item/var/etca, check sample)
- NST_BARTER	(4) Barter Shop (each item with own item currency)
- NST_EXPANDED_BARTER	(5) Expanded Barter Shop (buy items and spend zeny and items)
Unless otherwise specified via *tradertype an trader object will be defined as
NST_ZENY.

Note: NST_MARKET is only available with PACKETVER 20131223 or newer.
Note: NST_BARTER is only available with PACKETVER 20190116 main or 20190116 RE or 20181226 zero or newer.
Note: NST_EXPANDED_BARTER is only available with PACKETVER 20190904 main or 20190904 RE or 20190828 zero or newer.
See '12 - NPC Trader-Related Commands' and /doc/sample/npc_trader_sample.txt for
more information regarding how to use this NPC type.

** Define an warp/shop/cashshop/NPC duplicate.

warp: <map name>,<x>,<y>{,<facing>}%TAB%duplicate(<label>)%TAB%<NPC Name>%TAB%<spanx>,<spany>
shop/cashshop/npc: -%TAB%duplicate(<label>)%TAB%<NPC Name>%TAB%<sprite>
shop/cashshop/npc: <map name>,<x>,<y>,<facing>%TAB%duplicate(<label>)%TAB%<NPC Name>%TAB%<sprite>
npc: -%TAB%duplicate(<label>)%TAB%<NPC Name>%TAB%<sprite>,<triggerX>,<triggerY>
npc: <map name>,<x>,<y>,<facing>%TAB%duplicate(<label>)%TAB%<NPC Name>%TAB%<sprite>,<triggerX>,<triggerY>

This will duplicate an warp/shop/cashshop/NPC referred to by 'label'.
Warp duplicates inherit the target location.
Shop/cashshop duplicates inherit the item list.
NPC duplicates inherit the script code.
The rest (name, location, facing, sprite, span/trigger area) is
obtained from the definition of the duplicate (not inherited).

** Define a function object

function%TAB%script%TAB%<function name>%TAB%{<code>}

This will define a function object, callable with the 'callfunc' command
(see below). This object will load on every map server separately, so you
can get at it from anywhere. It's not possible to call the code in this
object by anything other than the 'callfunc' script command.

The code part is the script code that will execute whenever the function
is called with 'callfunc'. It has to be in curly brackets, unlike
elsewhere where we use curly brackets, these do NOT signify an optional
parameter.

Once an object is defined which has a 'code' field to it's definition, it
contains script commands which can actually be triggered and executed.

~ RID? GID? ~

What a RID is and why do you need to know
-----------------------------------------

Most scripting commands and functions will want to request data about a
character, store variables referenced to that character, send stuff to the
client connected to that specific character. Whenever a script is invoked
by a character, it is passed a so-called RID - this is the account ID
number of a character that caused the code to execute by clicking on it,
walking into it's OnTouch zone, or otherwise.

If you are only writing common NPCs, you don't need to bother with it.
However, if you use functions, if you use timers, if you use clock-based
script activation, you need to be aware of all cases when a script
execution can be triggered without a RID attached. This will make a lot of
commands and functions unusable, since they want data from a specific
character, want to send stuff to a specific client, want to store
variables specific to that character, and they would not know what
character to work on if there's no RID.

Unless you use 'attachrid' to explicitly attach a character to the script
first (see player-related commands).

Whenever we say 'invoking character', we mean 'the character who's RID is
attached to the running script. The script function playerattached() can
be used to check which is the currently attached player to the script (it
will return 0 if the there is no player attached or the attached player no
longer is logged on to the map-server).

But what about GID?
--- ---- ----- ----

GID stands for the Game ID of something, this can either be the GID of a
mob obtained through the monster() script command (if only summoned one),
the GID of a NPC obtained through the getnpcid() script command or the
account ID of a character (same as its RID). Another way would be to right
click on a mob, NPC or char as GM sprited char to view its GID.

Item and pet scripts
--------------------

Each item in the item database has three special fields - Script,
OnEquip_Script and OnUnequip_Script. The first is script code run every
time a character equips the item, with the RID of the equipping character.
Every time they unequip an item, all temporary bonuses given by the script
commands are cleared, and all the scripts are executed once again to
rebuild them. This also happens in several other situations (like upon
login) but the full list is currently unknown.

OnEquip_Script is a piece of script code run whenever the item is used by
a character by double-clicking on it. OnUnequip_Script runs whenever the
equipment is unequipped by a character.

Not all script commands work properly in the item scripts. Where commands
and functions are known to be meant specifically for use in item scripts,
they are described as such.

Every pet in the pet database has a PetScript field, which determines pet
behavior. It is invoked wherever a pet of the specified type is spawned
(hatched from an egg, or loaded from the char server when a character who
had that pet following them connects). This may occur in some other
situations as well. Don't expect anything other than commands definitely
marked as usable in pet scripts to work in there reliably.

Numbers
-------

The Hercules scripting engine supports 4 types of number literals:

type          base      syntax
----------------------------------------------
decimal       10        255
hexadecimal   16        0xFF
octal         8         0o377
binary        2         0b11111111

Beside the common decimal numbers, which are nothing special whatsoever
(though do not expect to use fractions, since ALL numbers are integer in
this language), the script engine also handles hexadecimal numbers, which
are otherwise identical. Writing a number like '0x<hex digits>' will make
it recognized as a hexadecimal value. Notice that 0x10 is equal to 16.
Also notice that if you try to 'mes 0x10' it will print '16'. If you wish
to make calculations in base 8, you can also use the octal notation like
'0o<octal digits>'. To make calculations in base 2 (binary), you can use
the binary notation like '0b<binary digits>'.

The following are all equivalent:
	255 == 0xFF == 0o377 == 0b11111111

Number values can't exceed the limits of an integer variable: Any number
greater than INT_MAX (2147483647) or smaller than INT_MIN (-2147483648) will
be capped to those values and will cause a warning to be reported.

Underscores can also be used as visual separators for digit grouping purposes:
	2_147_483_647
	0x7FFF_FFFF

Keep in mind that number literals cannot start or end with a separator and no
more than one separator can be used in a row (so 12_3___456 is illegal).

Variables
---------

The meat of every programming language is variables - places where you
store data.

In Hercules scripting language, variable names are case sensitive. Even though
at the current time the script engine accepts them even with the incorrect
case, it is not advised to rely on this behavior, as it may change at any
time.

Variables are divided into and uniquely identified by the combination of:
prefix  - determines the scope and extent (or lifetime) of the variable
name    - an identifier consisting of '_' and alphanumeric characters
postfix - determines the type of the variable: integer or string

Scope can be:
global    - global to all servers
local     - local to the server
account   - attached to the account of the character identified by RID
character - attached to the character identified by RID
npc       - attached to the NPC
scope     - attached to the scope of the instance

Extent can be:
permanent - They still exist when the server resets.
temporary - They cease to exist when the server resets.

Prefix: scope and extent
nothing  - A permanent variable attached to the character, the default
           variable type.
"@"      - A temporary variable attached to the character.
           They disappear when the character logs out.
"$"      - A global permanent variable.
           They are stored in database table `mapreg`.
"$@"     - A global temporary variable.
           They are important for scripts which are called with no RID
           attached, that is, not triggered by a specific character object.
"."      - A NPC variable.
           They exist in the NPC and disappear when the server restarts or
           the NPC is reloaded. Can be accessed from inside the NPC or by
           calling 'getvariableofnpc'. Function objects can also have
           .variables which are accessible from inside the function,
           however 'getvariableofnpc' does NOT work on function objects.
".@"     - A scope variable.
           They are unique to the character, script and scope. Each script
           execution has its own scope that ends when the script ends.
           Calling a function with callsub()/callfunc() starts a new scope,
           returning from the function ends it. When a scope ends, its
           variables are converted to values ('return .@var;' returns a
           value, not a reference).
"'"      - An instance variable.
           These are used with the instancing system, and are unique to
           each instance.
"#"      - A permanent local account variable.
"##"     - A permanent global account variable stored by the login server.
           The only difference you will note from normal # variables is
           when you have multiple char-servers connected to the same
           login-server. The # variables are unique to each char-server,
           while the ## variables are shared by all these char-servers.

Postfix: integer or string
nothing - integer variable, can store positive and negative numbers, but
          only whole numbers (so don't expect to do any fractional math).
'$'     - string variable, can store text.

Examples:
  name  - permanent character integer variable
  name$ - permanent character string variable
 @name  - temporary character integer variable
 @name$ - temporary character string variable
 $name  - permanent global integer variable
 $name$ - permanent global string variable
$@name  - temporary global integer variable
$@name$ - temporary global string variable
 .name  - NPC integer variable
 .name$ - NPC string variable
.@name  - scope integer variable
.@name$ - scope string variable
 'name  - instance integer variable
 'name$ - instance string variable
 #name  - permanent local account integer variable
 #name$ - permanent local account string variable
##name  - permanent global account integer variable
##name$ - permanent global account string variable

If a variable was never set, it is considered to equal zero for integer
variables or an empty string ("", nothing between the quotes) for string
variables. Once you set it to that, the variable is as good as forgotten
forever, and no trace remains of it even if it was stored with character
or account data. The maximum length of variable name including prefix and
suffix is 32. Permanent string variables (name$, $name$, #name$, ##name$)
can store text with a maximum length of 255 characters. All other string
type variables have no such limitation.

Some variables are special, that is, they are already defined for you by
the scripting engine. You can see the full list somewhere in
'doc/constants.md', which is a file you should read, since it also
allows you to replace lots of numbered arguments for many commands with
easier to read text. The special variables most commonly used are all
permanent character-based variables:

Zeny        - Amount of Zeny in the inventory.
BankVault   - Amount of Zeny in the bank.
Hp          - Current amount of hit points.
MaxHp       - Maximum amount of hit points.
Sp          - Current spell points.
MaxSp       - Maximum amount of spell points.
StatusPoint - Amount of status points remaining.
SkillPoint  - Amount of skill points remaining.
BaseLevel   - Character's base level.
JobLevel    - Character's job level.
BaseExp     - Amount of base experience points.
JobExp      - Amount of job experience points.
NextBaseExp - Amount of base experience points needed to reach next level.
NextJobExp  - Amount of job experience points needed to reach next level.
Weight      - Amount of weight the character currently carries.
              Display as in Weight/10.
MaxWeight   - Maximum weight the character can carry.
              Display as in MaxWeight/10.
Sex         - Character's gender (SEX_MALE or SEX_FEMALE).
Class       - Character's job.
Upper       - 0 if the character is normal class, 1 if advanced, 2 if baby.
BaseClass   - The character's 1-1 'normal' job, regardless of Upper value.
              For example, this will return Job_Acolyte for Acolyte,
              Priest/Monk, High Priest/Champion, and Arch Bishop/Sura.
              If the character has not reached a 1-1 class, it will return
              Job_Novice.
BaseJob     - The character's 'normal' job, regardless of Upper value.
              For example, this will return Job_Acolyte for Acolyte,
              Baby Acolyte, and High Acolyte.
Karma       - The character's karma. Karma system is not fully functional,
              but this doesn't mean this doesn't work at all. Not tested.
Manner      - The character's manner rating. Becomes negative if the
              player utters words forbidden through the use of
              'manner.txt' client-side file.

While these behave as variables, do not always expect to just set them -
it is not certain whether this will work for all of them. Whenever there
is a command or a function to set something, it's usually preferable to
use that instead. The notable exception is Zeny, which you can and often
will address directly - setting it will make the character own this number
of Zeny. If you try to set Zeny to a negative number, the script will be
terminated with an error.

Assigning variables
--------- ---------

Variables can be accessed and assigned values directly without the use of
the built-in 'set' function. This means that variables can be accessed and
modified much like other programming languages.

    .@x = 100;
    .@x = .@y = 100;

Support for modifying variable values using 'set' is still supported (and
required to exist for this method to work) so previous scripts will
continue working. Its usage, though, is deprecated, and it should never be
used in new scripts unless there are special reasons to do so.

When assigning values, all operator methods are supported which exist in
the below 'Operators' section. For instance:

    .@x += 100;
    .@x -= 100;
    .@x *= 2;
    .@x /= 2;
    .@x %= 5;
    .@x >>= 2;
    .@x <<= 2;

Will all work. For more information on available operators, see the
Operators section described below. All operators listed there may be
placed in-front of the '=' sign when modifying variables to perform the
action as required.

Increment and decrement operators are also provided, for your convenience.
Pre-increment and pre-decrement operators:

    ++.@x; // same as .@x = .@x + 1
    --.@x; // same as .@x = .@x - 1

Post-increment and post-decrement operators:

    .@x++; // similar to .@x = .@x + 1
    .@x--; // similar to .@x = .@x - 1

The difference between pre- and post- increment/decrement operators is that,
when used in an expression, the pre- ones will be executed before evaluating
the expression, while the post- ones will be executed after. For example:

    .@x = 1;
    .@y = ++.@x; // After this line is executed, both .@y and .@x will be 2
    .@x = 1;
    .@y = .@x++; // After this line is executed, .@y will be 1, .@x will be 2

Note: The pre-increment/pre-decrement operators are, by design, faster (or at
least not slower) than their respective post- equivalent.

Note:

 !! Currently the scripting engine does not support directly copying array
 !! variables. In order to copy arrays between variables the use of
 !! 'copyarray' function is still required.

Strings
-------

Strings are enclosed in "double quotes". To include the literal double
quote symbol (") in a string you need to escape it with a blackslash:

    .@string$ = "This string contains some \"double quote\" symbols";

Arrays
------

Arrays (in Hercules at least) are essentially a set of variables going
under the same name. You can tell between the specific variables of an
array with an 'array index', a number of a variable in that array:

<variable name>[<array index>]

All variable types can be used as arrays.

Variables stored in this way, inside an array, are also called 'array
elements'. Arrays are specifically useful for storing a set of similar
data (like several item IDs for example) and then looping through it. You
can address any array variable as if it was a normal variable:

    .@arrayofnumbers[0] = 1;

You can use a variable (or an expression, or even a value from an another
array) as array index:

    .@x = 100;
    .@arrayofnumbers[.@x] = 10;

This will make .@arrayofnumbers[100] equal to 10.

Index numbering always starts with 0 and arrays can hold over 2 billion
variables. As such, the (guaranteed) allowed values for indices are in the
range 0 ~ 2147483647.

If the array index is omitted, it defaults to zero. Writing
.@arrayofnumbers is perfectly equivalent to writing .@arrayofnumbers[0].

Arrays can naturally store strings:

.@menulines$[0] is the 0th element of the .@menulines$ array of strings.
Notice the '$', normally denoting a string variable, before the square
brackets that denotes an array index.

Variable References
-------------------

//##TODO

Hard-coded constants
--------------------
Most of the constants defined by the scripting engine can be found in
'doc/constants.md' and have the same value independently of settings
that are core related, but there are constants that can be used to
retrieve core information that's set when the server is compiled.

PACKETVER			- Server packet version
MAX_LEVEL			- Maximum level
MAX_STORAGE			- Maximum storage items
MAX_GUILD_STORAGE	- Maximum guild storage items
MAX_CART			- Maximum cart items
MAX_INVENTORY		- Maximum inventory items
MAX_ZENY			- Maximum Zeny in the inventory
MAX_BANK_ZENY		- Maximum Zeny in the bank
MAX_BG_MEMBERS		- Maximum BattleGround members
MAX_CHAT_USERS		- Maximum Chat users
MAX_REFINE			- Maximum Refine level
MAX_ITEM_ID			- Maximum Item ID
MAX_MENU_OPTIONS    - Maximum NPC menu options
MAX_MENU_LENGTH     - Maximum NPC menu string length
MOB_CLONE_START     - Clone ID start from this range
MOB_CLONE_END       - Clone ID end with this range

Send targets and status options are also hard-coded and can be found
in 'doc/constants.md'.

Operators
---------

Operators are things you can do to variables and numbers. They are either
the common mathematical operations or conditional operators:

+ - will add two numbers. If you try to add two strings, the result will
    be a string glued together at the +. You can add a number to a string,
    and the result will be a string. No other math operators work with
    strings.
- - will subtract two numbers.
* - will multiply two numbers.
** - will raise the first number to the power of the second number.
/ - will divide two numbers. Note that this is an integer division, i.e.
    7/2 is not equal 3.5, it's equal 3.
% - will give you the remainder of the division. 7%2 is equal to 1.

There are also conditional operators. This has to do with the conditional
command 'if' and they are meant to return either 1 if the condition is
satisfied and 0 if it isn't. That's what they call 'boolean' variables. 0
means 'False'. Anything except the zero is 'True'. Odd as it is, -1 and -5
and anything below zero will also be True.)

You can compare numbers to each other and you compare strings to each
other, but you can not compare numbers to strings.

 ==  - Is true if both sides are equal. For strings, it means they contain
       the same value.
 >=  - True if the first value is equal to, or greater than, the second
       value.
 <=  - True if the first value is equal to, or less than, the second value.
 >   - True if the first value greater than the second value.
 <   - True if the first value is less than the second value.
 !=  - True if the first value IS NOT equal to the second one.
 ~=  - True if the second value (as regular expression) matches the first
       value. Both values must be strings. See the script function pcre_match()
       for more details and advanced features.
 ~!  - True if the second value (as regular expression) DOES NOT match the
       first value. Both values must be strings. See script function pcre_match()
       for more details and advanced features.

Examples:

 1==1 is True.
 1<2 is True while 1>2 is False.
 .@x>2 is True if .@x is equal to 3. But it isn't true if .@x is 2.

Only '==', '!=', '~=' and '~!' have been tested for comparing strings. Since
there's no way to code a seriously complex data structure in this language,
trying to sort strings by alphabet would be pointless anyway.

Comparisons can be stacked in the same condition:

 && - Is True if and only if BOTH sides are true.
      ('1==1 && 2==2' is true. '2==1 && 1==1' is false.)
 || - Is True if either side of this expression is True.

 1==1 && 2==2 is True.
 1==1 && 2==1 is False.
 1==1 || 2==1 is True.

Logical bitwise operators work only on numbers, and they are the following:

 << - Left shift.
 >> - Right shift.
	Left shift moves the binary 1(s) of a number n positions to the left,
    which is the same as multiplying by 2, n times.
	In the other hand, Right shift moves the binary 1(s) of a number n
    positions to the right, which is the same as dividing by 2, n times.
		Example:
		b = 2;
		a =  b << 3;
		mes(a);
		a = a >> 2;
		mes(a);
	The first mes() command would display 16, which is the same as:
    2 x (2 x 2 x 2) = 16.
	The second mes() command would display 4, which is the same as:
    16 / 2 = 8; 8 / 2 = 4.
 &  - And.
 |  - Or.
	The bitwise operator AND (&) is used to test two values against each
    other, and results in setting bits which are active in both arguments.
    This can be used for a few things, but in Hercules this operator is
    usually used to create bit-masks in scripts.

	The bitwise operator OR (|) sets to 1 a binary position if the binary
    position of one of the numbers is 1. This way a variable can hold
    several values we can check, known as bit-mask. A variable currently
    can hold up to 32 bit-masks (from position 0 to position 1). This is a
    cheap(skate) and easy way to avoid using arrays to store several
    checks that a player can have.

	A bit-mask basically is (ab)using the variables bits to set various
    options in one variable. With the current limit in variables it is
    possible to store 32 different options in one variable (by using the
    bits on position 0 to 31).

	Example(s):
	- Basic example of the & operator, bit example:
		10 & 2 = 2
	Why? :
		10 = 2^1 + 2^3 (2 + 8), so in bits, it would be 1010
		2 = 2^1 (2), so in bits (same size) it would be 0010
		The & (AND) operator sets bits which are active (1) in both
        arguments, so in the example 1010 & 0010, only the 2^1 bit is
        active (1) in both. Resulting in the bit 0010, which is 2.
	- Basic example of creating and using a bit-mask:
		.@options = 2|4|16; // (note: this is the same as 2+4+16, or 22)
		if (.@options & 1)
			mes("Option 1 is activated");
		if (.@options & 2)
			mes("Option 2 is activated");
		if (.@options & 4)
			mes("Option 3 is activated");
		if (.@options & 8)
			mes("Option 4 is activated");
		if (.@options & 16)
			mes("Option 5 is activated");
	This would print the messages about option 2, 3 and 5 (since we've set
	the 2,4 and 16 bit to 1).
 ^  - Xor.
	The bitwise operator XOR (eXclusive OR) sets a binary position to 0 if
    both numbers have the same value in the said position. On the other
    hand, it sets to 1 if they have different values in the said binary
    position. This is another way of setting and unsetting bits in
    bit-masks.

	Example:
	- First let's set the quests that are currently in progress:
		inProgress = 1|8|16; // quest 1,8 and 16 are in progress
	- After playing for a bit, the player starts another quest:
		if (inProgress&2 == 0) {
			// this will set the bit for quest 2 (inProgress has that bit set to 0)
			inProgress = inProgress^2;
			mes("Quest 2: find a newbie and be helpful to him for an hour.");
			close();
		}
	- After spending some time reading info on Xor's, the player finally
      completes quest 1:
		if (inProgress&1 && isComplete) {
			// this will unset the bit for quest 1 (inProgress has that bit set to 1)
			inProgress = inProgress^1;
			mes("Quest 1 complete!! You unlocked the secrets of the Xor dynasty, use them wisely.");
			close();
		}

Unary operators with only with a single number, which follows the
operator, and are the following:

 -  - Negation.
	The sign of the number will be reversed. If the number was positive,
    it will become negative and vice versa.

	Example:
		.@myvar = 10;
		mes("Negative 10 is "+(-.@myvar));

 !  - Logical Not.
	Reverses the boolean result of an expression. True will become false
	and false will become true.

	Example:
		if (!callfunc("F_dosomething")) {
			mes("Doing something failed.");
			close();
		}

 ~  - Bitwise Not.
	Reverses each bit in a number, also known as one's complement. Cleared
    bits are set, and set bits are cleared.

	Example:
	- Ensure, that quest 2 is disabled, while keeping all other active, if
      they are.
		inProgress = inProgress&(~2);
		// same as set inProgress, inProgress&0xfffffffd

Ternary operators take three expressions (numbers, strings or boolean),
and are the following:

 ?: - Conditional operator
	Very useful e.g. to replace

		if (Sex == SEX_MALE)
			mes("You're Male.");
		else
			mes("You're Female.");

	clauses with simple

		mes("Welcome, " + (Sex == SEX_MALE ? "Mr." : "Mrs.") + " " + strcharinfo(PC_NAME));

	or to replace any other simple if-else clauses. It might be worth
	mentioning that ?: has low priority and has to be enclosed with
	parenthesis in most (if not all) cases.

Operator Precedence and Associativity

Operator precedence and associativity work more or less like they do in
mathematics. The rules can be summarized with the following table:

Precedence  |  Description                                  | Associativity
---------------------------------------------------------------------------
1 (highest) | []  Array subscripting                        | None
---------------------------------------------------------------------------
2           | ++  Increment                                 | None

            |  !  Logical NOT                               |

            | <=  Less than or equal to                     |
            |  >  Greater than                              |
            | >=  Greater than or equal to                  |
---------------------------------------------------------------------------

            | !=  Not equal to                              |
            | ~=  Regexp match                              |
            | ~!  Regexp non-match                          |

            | &=  Assignment by bitwise AND                 |
            | ^=  Assignment by bitwise XOR                 |
            | |=  Assignment by bitwise OR                  |

Operator precedence means some operators are evaluated before others. For
example, in 2 + 4 * 5 , the multiplication has higher precedence so 4 * 5 is
evaluated first yielding 2 + 20 == 22 and not 6 * 5 == 30 .

Operator associativity defines what happens if a sequence of the same
operators is used one after another: whether the evaluator will evaluate the
left operations first or the right. For example, in 8 - 4 - 2 , subtraction is
left associative so the expression is evaluated left to right. 8 - 4 is
evaluated first making the expression 4 - 2 == 2 and not 8 - 2 == 6 .

Labels
------

Within executable script code, some lines can be labels:

<label name>:

Labels are points of reference in your script, which can be used to route
execution with 'goto' and 'menu' commands, invoked with 'doevent', 'donpcevent'
and 'callsub' commands and are otherwise essential. A label's name may not be
longer than 23 characters. (24th is the ':'.) It may only contain alphanumeric
characters and underscore. In addition to labels you name yourself, there are
also some special labels which the script engine will start execution from if
a special event happens:

OnClock<hour><minute>:
OnMinute<minute>:
OnHour<hour>:
On<weekday><hour><minute>:
OnDay<month><day>:

This will execute when the server clock hits the specified date or time.
Hours and minutes are given in military time. ('0105' will mean 01:05 AM).
Weekdays are Sun, Mon, Tue, Wed, Thu, Fri, Sat. Months are 01 to 12, days are
01 to 31. Remember the zero. :)

OnInit:
OnInterIfInit:
OnInterIfInitOnce:

OnInit will execute every time the scripts loading is complete, including
when they are reloaded with @reloadscript command. OnInterIfInit will
execute when the map server connects to a char server, OnInterIfInitOnce
will only execute once and will not execute if the map server reconnects
to the char server later. Note that all those events will be executed upon
scripts reloading.

OnNPCUnload:

OnNPCUnload will be executed when a NPC is unloaded.
OnNPCUnload is called when @reloadscript, @reloadnpc, @unloadnpc or @unloadnpcfile is used.

OnAgitStart:
OnAgitEnd:
OnAgitInit:
OnAgitStart2:
OnAgitEnd2:
OnAgitInit2:

OnAgitStart will run whenever the server shifts into WoE mode, whether it
is done with @agitstart GM command or with 'AgitStart' script command.
OnAgitEnd will do likewise for the end of WoE.

OnAgitInit will run when data for all castles and all guilds that hold a
castle is received by map-server from the char-server after initial
connect.

No RID will be attached while any of the above mentioned labels are
triggered, so no character or account-based variables will be accessible,
until you attach a RID with 'attachrid' (see below).

The above also applies to, the last three labels, the only difference is
that these labels are used exclusively for WoE SE, and are called
independently.

OnInstanceInit:

This label will be executed when an instance is created and initialized through
the 'instance_init' command. It will run again if @reloadscript is used while
an instance is in progress.

OnTouch:

This label will be executed if a trigger area is defined for the NPC
object it's in. If it isn't present, the execution will start from the
beginning of the NPC code. The RID of the triggering character object will
be attached.

OnTouch_:

Similar to OnTouch, but will only run one instance. Another character is
chosen once the triggering character leaves the area.

OnUnTouch:

This label will be executed if plater leave trigger area is defined for the NPC
object it's in. If it isn't present, nothing will happend.
The RID of the triggering character object will be attached.

OnPCLoginEvent:
OnPCLogoutEvent:
OnPCBaseLvUpEvent:
OnPCJobLvUpEvent:

It's pretty obvious when these four special labels will be invoked.

OnPCDieEvent:

This special label triggers when a player dies. The variable 'killerrid'
is set to the ID of the killer.

OnPCKillEvent:

This special label triggers when a player kills another player. The
variable 'killedrid' is set to the ID of the player killed.

OnNPCKillEvent:

This special label triggers when a player kills a monster. The variable
'killedrid' is set to the Class of the monster killed.

OnPCLoadMapEvent:

This special label will trigger once a player steps in a map marked with
the 'loadevent' mapflag and attach its RID. The fact that this label
requires a mapflag for it to work is because, otherwise, it'd be
server-wide and trigger every time a player would change maps. Imagine the
server load with 1,000 players (oh the pain...)

Only the special labels which are not associated with any script command
are listed here. There are other kinds of labels which may be triggered in
a similar manner, but they are described with their associated commands.

OnCountFunds:

This special label is triggered when a player opens a trader NPC object that
is NST_CUSTOM. It is used to define different currency types to the trader via
setcurrency(). Should be used along with OnPayFunds, see
doc/sample/npc_trader_sample.txt for more information.

OnPayFunds:

This special label is triggered when a purchase is made on a trader NPC object
that is NST_CUSTOM. Receives @price, total cost and @points, secondary input
field for cash windows. It is used to remove items that are set as currency.
Should be used along with OnCountFunds, see /doc/sample/npc_trader_sample.txt
for more information.

On<label name>:

These special labels are used with Mob scripts mostly, and script commands
that requires you to point/link a command to a mob or another NPC, giving
a label name to start from. The label name can be any of your liking, but
must be started with "On".

Example:

monster("prontera", 123, 42, "Poringz0rd", 2341, 23, "Master::OnThisMobDeath");

amatsu,13,152,4	script	Master	767,{
	mes("Hi there");
	close();

OnThisMobDeath:
	announce("Hey, "+strcharinfo(PC_NAME)+" just killed a Poringz0rd!", bc_blue|bc_all);
	end;
}

Each time you kill one, that announce will appear in blue to everyone.

"Global" labels

There's a catch with labels and doevent(). If you call a label (using
doevent()) and called label is in NPC that has trigger area, that label must
end with "Global" to work globally (i.e. if RID is outside of the trigger area,
which usually happens since otherwise there would be no point calling the label
with doevent(), because OnTouch would do the job). For further reference look
for npc_event in npc.c.

Scripting commands and functions
--------------------------------

The commands and functions are listed here in no particular order. There's
a difference between commands and functions - commands leave no 'return
value' which might be used in a conditional statement, as a command
argument, or stored in a variable.

All instructions must end with a ';'. Actually, you may expect to have multiple
instructions on one line if you properly terminate them with a ';', but it's
consider ill practice, since it impairs legibility of the script.

Please note that command and function names are case sensitive.

-------------------------


From here on, we will have the commands sorted as followed:

1 - Basic Commands
2 - Information-Retrieving Commands
    -- 2.1 - Item-Related Commands
    -- 2.2 - Guild-Related Commands
3 - Checking Commands
    -- 3.1 - Checking Item-Related Commands
4 - Player-Related Commands

//=====================================
1 - Basic Commands
//=====================================
---------------------------------------

*mes("<string>")

This command will displays a box on the screen for the invoking character,
if no such box is displayed already, and will print the string specified
into that box. There is normally no 'close' or 'next' button on this box,
unless you create one with 'close' or 'next', and while it's open the
player can't do much else, so it's important to create a button later. If
the string is empty, it will show up as an empty line.

    mes("Text that will appear in the box");

Inside the string you may put color codes, which will alter the color of
the text printed after them. The color codes are all '^<R><G><B>' and
contain three hexadecimal numbers representing colors as if they were
HTML colors - ^FF0000 is bright red, ^00FF00 is bright green, ^0000FF is
bright blue, ^000000 is black. ^FF00FF is a pure magenta, but it's also
a color that is considered transparent whenever the client is drawing
windows on screen, so printing text in that color will have kind of a
weird effect.  You may also use C_ constants accompany with "F_MesColor"
function for the color effect, see the full list of the available ones
in 'db/constants.conf' under 'C_'. Once you've set a text's color to something,
you have to set it back to black unless you want all the rest of the text be in
that color:

    mes("This is ^FF0000 red ^000000 and this is ^00FF00 green, ^000000 so.");
    mesf("%sThis message is now in BLUE.", F_MesColor(C_BLUE));

Notice that the text coloring is handled purely by the client. If you use
non-English characters, the color codes might get screwed if they stick to
letters with no intervening space. Separating them with spaces from the
letters on either side solves the problem.

If you're using a client from 2011-10-10aRagexe.exe onwards, you can also
use automatic navigation and open URLs in browser by using some HTML-like
labels. For example:

    mes("go to <NAVI>[Hat Maker]<INFO>izlude,131,148,</INFO></NAVI> to make hats");

Will make the [Hat Maker] text clickable in the client and start a navigation
to that point.

    mes("You can <URL>Google<INFO>http://www.google.com/</INFO></URL> anything");

This will allow you to visit 'Google' with the in-game browser using default dimensions.

    mes("You can <URL>Bing!<INFO>http://www.bing.com/,800,600</INFO></URL> anything");

Clicking 'Bing!' will open the in-game browser using the specified dimensions. (800x600)

If you're using client from 2013-01-30 onwards, you can also use <ITEMLINK> to show
the item's description. Gravity changed this into <ITEM> since 2015-07-29 onwards.

    mes("Bring me an <ITEM>Apple<INFO>512</INFO></ITEM>.");
    mesf("Bring me an %s.", F_MesItemInfo(Apple));

This will show the item name and a clickable link for the item description.

---------------------------------------

*mesf("<format>"{, <param>{, <param>{, ...}}})

This command will display a box on the screen for the invoking character,
if no such box is displayed already, and will print the string specified
into that box, after applying the same format-string replacements as sprintf().

Example:

	mesf("Hello, I'm %s, a level %d %s", strcharinfo(PC_NAME), BaseLevel, jobname(Class));
	// is equivalent to:
	mes(sprintf("Hello, I'm %s, a level %d %s", strcharinfo(PC_NAME), BaseLevel, jobname(Class)));

This command is a combination of mes() and sprintf(). See their documentation
for more details.

---------------------------------------

*next()

This command will display a 'next' button in the message window for the
invoking character. Clicking on it will cause the window to clear and
display a new one. Used to segment NPC-talking, next() is often used in
combination with mes() and close().

If no window is currently on screen, one will be created, but once the
invoking character clicks on it, a warning is thrown on the server console
and the script will terminate.

    mes("[Woman]");
    mes("This would appear on the page");
    next();
    mes("[Woman]"); // This is needed since it is a new page and the top will now be blank
    mes("This would appear on the 2nd page");

---------------------------------------

*mesclear();

This command will clear the dialog text and continue the script without player interaction.

Example:
	mes("This is how the 'mesclear' script command works.");
	sleep2 3000;
	mesclear(); // This will clear the dialog and continue to the next one.
	mes("I will show you again.");
	sleep2 3000;
	mesclear(); // This will clear the dialog and continue to the next one.
	mes("Bye!");

---------------------------------------

*close()

This command will create a 'close' button in the message window for the
invoking character. If no window is currently on screen, the script
command 'end;' must be used. This is one of the ways to end a speech from
an NPC. Once the button is clicked, the NPC script execution will end, and
the message box will disappear.

    mes("[Woman]");
    mes("I am finished talking to you, click the close button.");
    close();
    mes("This command will not run at all, since the script has ended.");

---------------------------------------

*close2()

This command will create a 'close' button in the message window for the
invoking character. WARNING: If no window is currently on screen, the
script execution will halt indefinitely! See 'close'. There is one
important difference, though - even though the message box will have
closed, the script execution will not stop, and commands after 'close2'
will still run, meaning an 'end' has to be used to stop the script, unless
you make it stop in some other manner.

    mes("[Woman]");
    mes("I will warp you now.");
    close2();
    warp("place", 50, 50);
    end;

Don't expect things to run smoothly if you don't make your scripts 'end'.

---------------------------------------

*end

This instruction will stop the execution for this particular script.
Note that this is to be considered a special instruction (not a regular
command or function), and as such doesn't require parentheses.

    if (BaseLevel <= 10) {
        npctalk("Look at that you are still a n00b");
        end;
    }
    if (BaseLevel <= 20) {
        npctalk("Look at that you are getting better, but still a n00b");
        end;
    }
    if (BaseLevel <= 30) {
        npctalk("Look at that you are getting there, you are almost 2nd profession now right???");
        end;
    }
    if (BaseLevel <= 40) {
        npctalk("Look at that you are almost 2nd profession");
        end;
    }

Without the use of 'end' it would travel through the ifs until the end
of the script. If you were lvl 10 or less, you would see all the speech
lines, the use of 'end' stops this, and ends the script.

---------------------------------------

*set(<variable>, <expression>)

This command will set a variable to the value that the expression results
in. This isn't the only way to set a variable directly: you can set them
much like any other programming language as stated before (refer to the
'Assigning variables' section).

This command is deprecated and it shouldn't be used in new scripts, except
some special cases (mostly, set(getvariableofnpc(), <value>)). Use direct value
assignment instead.

---------------------------------------

*setd("<variable name>", <value>)

Works almost identically as set(), except the variable name is
identified as a string and can thus be constructed dynamically.

This command is equivalent to:
  set(getd("variable name"), <value>);

Examples:

  setd(".@var$", "Poporing");
  mes(.@var$); // Displays "Poporing".

  setd(".@" + .@var$ + "123$", "Poporing is cool");
  mes(.@Poporing123$); // Displays "Poporing is cool".

---------------------------------------

*getd("<variable name>")

Returns a reference to a variable, the name can be constructed dynamically.
Refer to setd() for usage.

This can also be used to set an array dynamically:
  setarray(getd(".array[0]"), 1, 2, 3, 4, 5);

Examples:

  mes("The value of $varReference is: " + getd("$varRefence"));
  set(.@i, getd("$" + "pikachu"));

---------------------------------------

*getvariableofnpc(<variable>, "<npc name>")

Returns a reference to a NPC variable (. prefix) from the target NPC.
This can only be used to get . variables.

Examples:

//This will return the value of .var, note that this can't be used, since
//the value isn't caught.
	getvariableofnpc(.var, "TargetNPC");

//This will set the .@v variable to the value of the TargetNPC's .var
//variable.
	.@v = getvariableofnpc(.var, "TargetNPC");

//This will set the .var variable of TargetNPC to 1.
	set(getvariableofnpc(.var, "TargetNPC"), 1);

Note: even though function objects can have .variables,
getvariableofnpc() should not be used on them.

---------------------------------------

*getvariableofpc(<variable>, <account id>{, <default value>})

Returns a reference to a PC variable from the target player.
If <default value> is passed, it will return this value if the player is
not found.

Examples:

//This will return the value of @var, note that this can't be used, since
//the value isn't caught.
	getvariableofpc(@var, getcharid(CHAR_ID_ACCOUNT, "player"));

//This will set the .@v variable to the value of the player's @var
//variable.
	.@v = getvariableofpc(@var, getcharid(CHAR_ID_ACCOUNT, "player"));

//This will set the @var variable of the player to 1.
	set(getvariableofpc(@var, getcharid(CHAR_ID_ACCOUNT, "player")), 1);

---------------------------------------

*goto(<label>)

This command will make the script jump to a label, usually used in
conjunction with other instructions, such as "if", but often used on its own.

	...
	goto(Label);
	mes("This will not be seen");
Label:
	mes("This will be seen");

Gotos are considered to be harmful and should be avoided whenever possible.

---------------------------------------

*menu("<option_text>", <target_label>{, "<option_text>", <target_label>, ...})

This command will create a selectable menu for the invoking character.
Only one menu can be on screen at the same time.

Depending on what the player picks from the menu, the script execution
will continue from the corresponding label. It's string-label pairs, not
label-string.

This command is deprecated and it should not be used in new scripts, as it
is likely to be removed at a later time. Please consider using select() or
prompt() instead.

Options can be grouped together, separated by the character ':'.

	menu("A:B", L_Wrong, "C", L_Right);

It also sets a special temporary character variable @menu, which contains
the number of option the player picked. Numbering of options starts at 1.
This number is consistent with empty options and grouped options.

	menu("A::B", L_Wrong, "", L_Impossible, "C", L_Right);
	L_Wrong:
	// If they click "A" or "B" they will end up here
	// @menu == 1 if "A"
	// @menu == 2 will never happen because the option is empty
	// @menu == 3 if "B"
	L_Impossible:
	// Empty options are not displayed and therefore can't be selected
	// this label will never be reached from the menu command
	L_Right:
	// If they click "C" they will end up here
	// @menu == 5

If a label is '-', the script execution will continue right after the menu
command if that option is selected, this can be used to save you time, and
optimize big scripts.

	menu("A::B:", -, "C", L_Right);
	// If they click "A" or "B" they will end up here
	// @menu == 1 if "A"
	// @menu == 3 if "B"
	L_Right:
	// If they click "C" they will end up here
	// @menu == 5

Both these examples will perform the exact same task.

If you give an empty string as a menu item, the item will not display.
This can effectively be used to script dynamic menus by using empty string
for entries that should be unavailable at that time.

You can do it by using arrays, but watch carefully - this trick isn't high
wizardry, but minor magic at least. You can't expect to easily duplicate
it until you understand how it works.

Create a temporary array of strings to contain your menu items, and
populate it with the strings that should go into the menu at this
execution, making sure not to leave any gaps. Normally, you do it with a
loop and an extra counter, like this:

	setarray(.@possiblemenuitems$[0], <list of potential menu items>);
	.@j = 0; // That's the menu lines counter.

	// We loop through the list of possible menu items.
	// .@i is our loop counter.
	for (.@i = 0; .@i < getarraysize(.@possiblemenuitems$); ++.@i) {
		// That 'condition' is whatever condition that determines whether
		// a menu item number .@i actually goes into the menu or not.

		if (<condition>) {
			// We record the option into the list of options actually
			// available.
			.@menulist$[.@j] = .@possiblemenuitems$[.@i];

			// We just copied the string, we do need it's number for later
			// though, so we record it as well.
			.@menureference[.@j] = .@i;

			// Since we've just added a menu item into the list, we
			// increment the menu lines counter.
			++.@j;
		}

		// We go on to the next possible menu item.
	}

This will create you an array .@menulist$ which contains the text of all
items that should actually go into the menu based on your condition, and
an array .@menureference, which contains their numbers in the list of
possible menu items. Remember, arrays start with 0. There's less of them
than the possible menu items you've defined, but the menu() command can
handle the empty lines - only if they are last in the list, and if it's
made this way, they are. Now comes a dirty trick:

	// X is whatever the most menu items you expect to handle.
	menu(.@menulist$[0], -, .@menulist$[1], -, ..., .@menulist$[<X>], -);

This calls up a menu of all your items. Since you didn't copy some of the
possible menu items into the list, it's end is empty and so no menu items
will show up past the end. But this menu() call doesn't jump anywhere, it
just continues execution right after the menu() command. (And it's a good
thing it doesn't, cause you can only explicitly define labels to jump to,
and how do you know which ones to define if you don't know beforehand
which options will end up where in your menu?)
But how do you figure out which option the user picked? Enter the @menu.

@menu contains the number of option that the user selected from the list,
starting with 1 for the first option. You know now which option the user
picked and which number in your real list of possible menu items it
translated to:

    mes("You selected "+.@possiblemenuitems$[.@menureference[@menu-1]]+"!");

@menu is the number of option the user picked.
@menu-1 is the array index for the list of actually used menu items that
we made.
.@menureference[@menu-1] is the number of the item in the array of possible
menu items that we've saved just for this purpose.

And .@possiblemenuitems$[.@menureference[@menu-1]] is the string that we
used to display the menu line the user picked. (Yes, it's a handful, but
it works.)

You can set up a bunch of 'if (.@menureference[@menu-1]==X) goto(Y)'
statements to route your execution based on the line selected and still
generate a different menu every time, which is handy when you want to, for
example, make users select items in any specific order before proceeding,
or make a randomly shuffled menu.

Kafra code bundled with the standard distribution uses a similar
array-based menu technique for teleport lists, but it's much simpler and
doesn't use @menu, probably since that wasn't documented anywhere.

See also 'select', which is probably better in this particular case.
Instead of menu(), you could use select() like this:

    .@dummy = select(.@menulist$[0], .@menulist$[1], ..., .@menulist$[<X>]);

For the purposes of the technique described above these two statements are
perfectly equivalent.

---------------------------------------

*select("<option>"{, "<option>", ...})

This function is a handy replacement for 'menu' that doesn't use a complex
label structure. It will return the number of the menu option picked,
starting with 1. If the player presses cancel, the script is terminated.

    if (select("Yes", "No") == 1)
        mes("You said yes, I know.");

And like 'menu', the selected option is consistent with grouped options
and empty options.

---------------------------------------

*prompt("<option>"{, "<option>", ...})

This function behaves exactly like select(), but when a player presses cancel
it returns MAX_MENU_OPTIONS and the script is not terminated. You almost always
want to use select() rather than prompt().

---------------------------------------

*input(<variable>{, <min>{, <max>}})

This command will make an input box pop up on the client connected to the
invoking character, to allow entering of a number or a string. This has
many uses, one example would be a guessing game, also making use of the
'rand' function:

	mes("[Woman]");
	mes("Try and guess the number I am thinking of.");
	mes("The number will be between 1 and 10.");
	next();
	.@number = rand(1, 10);
	input(.@guess);
	if (.@guess == .@number) {
		mes("[Woman]");
		mes("Well done that was the number I was thinking of");
		close();
	} else {
		mes("[Woman]");
		mes("Sorry, that wasn't the number I was thinking of.");
		close();
	}

If you give the input() command a string variable to put the input in, it
will allow the player to enter text. Otherwise, only numbers will be
allowed.

	mes("[Woman]");
	mes("Please say HELLO");
	next();
	input(.@var$);
	if (.@var$ == "HELLO") {
		mes("[Woman]");
		mes("Well done you typed it correctly");
		close();
	} else {
		mes("[Woman]");
		mes("Sorry you got it wrong");
		close();
	}

Normally you may not input a negative number with this command.
This is done to prevent exploits in badly written scripts, which would let
people, for example, put negative amounts of Zeny into a bank script and
receive free Zeny as a result.

The command has two optional arguments and a return value.
The default value of 'min' and 'max' can be set with 'input_min_value' and
'input_max_value' in conf/map/script.conf.
For numeric inputs the value is capped to the range [min, max]. Returns 1
if the value was higher than 'max', -1 if lower than 'min' and 0 otherwise.
For string inputs it returns 1 if the string was longer than 'max', -1 is
shorter than 'min' and 0 otherwise. Note that an input string has a maximum
length of 70 characters.

---------------------------------------

*callfunc("<function>"{, <argument>, ...<argument>})

This command lets you call up a function NPC. A function NPC can be called
from any script on any map server. Using the 'return' instruction it
will come back to the place that called it.

	place,50,50,6%TAB%script%TAB%Woman%TAB%115,{
		mes("[Woman]");
		mes("Lets see if you win");
		callfunc("funcNPC");
		mes("Well done you have won");
		close();
	}
	function%TAB%script%TAB%funcNPC%TAB%{
		.@win = rand(2);
		if (.@win == 0)
			return;
		mes("Sorry you lost");
		end;
	}

You can pass arguments to your function - values telling it what exactly
to do - which will be available there with getarg() (see 'getarg').
Notice that returning is not mandatory, you can end execution right there.

If you want to return a real value from inside your function NPC, you
may do so:

	place,50,50,6%TAB%script%TAB%Man%TAB%115,{
		mes("[Man]");
		mes("Gimme a number!");
		next();
		input(.@number);
		if (callfunc("OddFunc", .@number))
			mes("It's Odd!");
		close();
	}
	function%TAB%script%TAB%OddFunc%TAB%{
		if (getarg(0)%2==0)
			return 0;// it's even
		return 1;// it's odd
	}

Alternately, user-defined functions may be called directly without the use
of the callfunc() script command.

	function<TAB>script<TAB>SayHello<TAB>{
		mes("Hello " + getarg(0));
		return 0;
	}

	place,50,50,6<TAB>script<TAB>Man<TAB>115,{
		mes("[Man]");
		SayHello(strcharinfo(PC_NAME));
		close();
	}

Note:

 !! A user-defined function must be declared /before/ a script attempts to
 !! call it. That is to say, any functions should be placed above scripts
 !! or NPCs (or loaded in a separate file first) before attempting to call
 !! them directly.

---------------------------------------

*callsub(<label>{, <argument>, ...<argument>})

This command will go to a specified label within the current script (do
NOT use quotes around it) coming in as if it were a 'callfunc' call, and
pass it arguments given, if any, which can be recovered there with
'getarg'. When done there, you should use the 'return' command to go back
to the point from where this label was called. This is used when there is
a specific thing the script will do over and over, this lets you use the
same bit of code as many times as you like, to save space and time,
without creating extra NPC objects which are needed with 'callfunc'. A
label is not callable in this manner from another script.

Example 1: callsub for checking (if checks pass, return to script)
	callsub(S_CheckFull, "guild_vs2", 50);
	switch (rand(4)) {
	case 0:
		warp("guild_vs2", 9, 50);
		end;
	case 1:
		warp("guild_vs2", 49, 90);
		end;
	case 2:
		warp("guild_vs2", 90, 50);
		end;
	case 3:
		warp("guild_vs2", 49, 9);
		end;
	}
	end;

S_CheckFull:
	if (getmapusers(getarg(0)) >= getarg(1)) {
		mes("I'm sorry, this arena is full.  Please try again later.");
		close();
	}
	return;

Example 2: callsub used repeatedly, with different arguments
// notice how the Zeny check/delete is reused, instead of copy-pasting for
// every warp.
	switch (select("Abyss Lake", "Amatsu Dungeon", "Anthell", "Ayothaya Dungeon", "Beacon Island, Pharos")) {
		case 1:
			callsub(S_DunWarp, "hu_fild05", 192, 207);
			break;
		case 2:
			callsub(S_DunWarp, "ama_in02", 119, 181);
			break;
		case 3:
			callsub(S_DunWarp, "moc_fild20", 164, 145);
			break;
		case 4:
			callsub(S_DunWarp, "ayo_fild02", 279, 150);
			break;
		case 5:
			callsub(S_DunWarp, "cmd_fild07", 132, 125);
			break;
		// etc
	}

// ...

S_DunWarp:
// getarg(0) = "mapname"
// getarg(1) = x
// getarg(2) = y
	if (Zeny >= 100) {
		Zeny -= 100;
		warp(getarg(0), getarg(1), getarg(2));
	} else {
		mes("Dungeon warp costs 100 Zeny.");
	}
	close();

---------------------------------------

*getarg(<index>{, <default_value>})

This function is used when you use the 'callsub' or 'callfunc' commands.
In the call you can specify variables that will make that call different
from another one. This function will return an argument the function or
subroutine was called with, and is the normal way to get them.
This is another thing that can let you use the same code more than once.

Argument numbering starts with 0, i.e. the first argument you gave is
number 0. If no such argument was given, a zero is returned.

	place,50,50,6%TAB%script%TAB%Woman1%TAB%115,{
		mes("[Woman]");
		mes("Lets see if you win");
		callfunc("funcNPC", 2);
		mes("Well done you have won");
		// ...
	}

	place,52,50,6%TAB%script%TAB%Woman2%TAB%115,{
		mes("[Woman]");
		mes("Lets see if you win");
		callfunc("funcNPC", 5);
		mes("Well done you have won");
		// ...
	}

	function%TAB%script%TAB%funcNPC%TAB%{
		.@win = rand(getarg(0));
		if (.@win == 0)
			return;
		mes("Sorry you lost");
		close();
	}

"woman1" NPC object calls the funcNPC. The argument it gives in this call
is stated as 2, so when the random number is generated by the 'rand'
function, it can only be 0 or 1. Whereas "woman2" gives 5 as the argument
number 0 when calling the function, so the random number could be 0, 1, 2,
3 or 4, this makes "woman2" less likely to say the player won.

You can pass multiple arguments in a function call:

	callfunc("funcNPC", 5, 4, 3);

getarg(0) would be 5, getarg(1) would be 4 and getarg(2) would be 3.

Getarg also has an optional argument:
If the target argument exists, it is returned.
Otherwise, if <default_value> is present it is returned instead, if not
the script terminates immediately.

In previous example getarg(2, -1) would be 3 and getarg(3, -1) would be -1.

---------------------------------------

*getargcount()

This function is used when you use the 'callsub' or 'callfunc' commands.
In the call you can specify arguments. This function will return the
number of arguments provided.

Example:
	callfunc("funcNPC", 5, 4, 3);
	// ...
	function%TAB%script%TAB%funcNPC%TAB%{
		.@count = getargcount(); // 3
		//...
	}

---------------------------------------

*return {<value>}

This instruction causes the script execution to leave previously called
function with callfunc() or script with callsub() and return to the
location, where the call originated from. Optionally a return value can
be supplied.

Using this command outside of functions or scripts referenced by callsub
will result in error and termination of the script.

	callfunc("<your function>"); // when nothing is returned
	<variable> = callfunc("<your function>"); // when a value is being returned

---------------------------------------

{public | private} *function <function name>;
{public | private} *function <function name> {
<code>
}

In its first form, this syntax declares a local function so it can later be
defined. In its second form, the syntax both declares and defines a local
function. Local functions must be defined before being used. Note that the name
may only contain alphanumeric characters and underscore. Once defined, they can
be called from the current script as if they were regular built-in commands, and
can also be called from other scripts if they are marked as public. Local
functions may be marked as public by simply adding "public" prior to the
function definition. Functions not marked as public are private by default and
cannot be called from another script.

Usage:

    1. Declare the function.
	function <function name>;
    2. Call the function anywhere within the script.
	<function name>();
    3. Define the function by adding its script.
	<function name> {<code>}

    Step 1 is optional if the function is defined prior to being called.

Example:

	/* Function declaration */
	function MyFunction;

	/* Function call */
	MyFunction();

	/* Function definition */
	function MyFunction {
		// (do something)
		return;
	}


Example with public functions:

	/* Function declaration + definition */
	public function myFunction {
		/* notice the "public" before the "function" keyword */
		return;
	}

	/* Local call */
	myFunction();

	/* Call from another script */
	"npc name"::myFunction();


Example with parameters and return value:

	/* Function declaration */
	function MyAdd;

	mes("Enter two numbers.");
	next();
	input(.@a);
	input(.@b);
	/* Function call */
	mesf("%i + %i = %i", .@a, .@b, MyAdd(.@a, .@b));
	close();

	/* Function definition */
	function MyAdd {
		return (getarg(0) + getarg(1));
	}


---------------------------------------

*<function name>({<arg>...})
*"<npc name>"::<function name>({<arg>...})
*callfunctionofnpc("<function name>", "<npc name>"{, <arg>...});

In its first form, calls a previously defined local function. In its second
form, calls a previously defined public local function of another NPC. If the
name of the target NPC or the name of the local function is not known
beforehand, callfunctionofnpc() can be used instead of the second form.
See function() above for more details.

Example:

	MyFunction(arg1, arg2, arg3);
	"MyNPC"::MyFunction(arg1, arg2, arg3);
	callfunctionofnpc("MyNPC", "MyFunction", arg1, arg2, arg3);

---------------------------------------

*is_function("<function name>")

This command checks whether or not a function exists and returns its type.
Returns false if it cannot be found.

return values:

	FUNCTION_IS_COMMAND - built-in script command (eg: mes, select, ...)
	FUNCTION_IS_GLOBAL  - user-defined global function (callable with callfunc)
	FUNCTION_IS_LOCAL   - user-defined local function
	FUNCTION_IS_LABEL   - user-defined label function (callable with callsub)

Example:

	function	script	func1	{
		dothat();
	}

	-	script	test	FAKE_NPC,{
		function func2 {
			do_something();
		}

	func3:
		end;

		is_function("func1"); // FUNCTION_IS_GLOBAL
		is_function("func2"); // FUNCTION_IS_LOCAL
		is_function("func3"); // FUNCTION_IS_LABEL
		is_function("select"); // FUNCTION_IS_COMMAND
		is_function("invalid"); // false
	}

---------------------------------------

*if (<condition>) <statement or block>

This is the basic conditional command.

The condition can be any expression. All expressions resulting in a
non-zero value will be considered True, including negative values. All
expressions resulting in a zero are false.

If the expression results in True, the statement will be executed. If it
isn't true, nothing happens and we move on to the next line of the script.

    if (true)
	mes("This will always print.");
    if (0)
	mes("And this will never print.");
    if (5)
	mes("This will also always print.");
    if (-1)
	mes("Funny as it is, this will also print just fine.");

For more information on conditional operators see the operators section
above.
Anything that is returned by a function can be used in a condition check
without bothering to store it in a specific variable:

	if (strcharinfo(PC_NAME) == "Daniel Jackson")
		mes("It is true, you are Daniel!");

More examples of using the 'if' command in the real world:

Example 1:

	.@var1 = 1;
	input(.@var2);
	if (.@var1 == .@var2)
		close();
	mes("Sorry that is wrong");
	close();

Example 2:

	.@var1 = 1;
	input(.@var2);
	if (.@var1 != .@var2)
		mes("Sorry that is wrong");
	close();

(Notice examples 1 and 2 have the same effect.)

Example 3:

	++@var1;
	mes("[Forgetfull Man]");
	if (@var == 1)
		mes("This is the first time you have talked to me");
	if (@var == 2)
		mes("This is the second time you have talked to me");
	if (@var == 3)
		mes("This is the third time you have talked to me");
	if (@var == 4)
		mes("This is the forth time you have talked to me, but I think I am getting amnesia, I have forgotten about you");
	if (@var == 4)
		@var = 0;
	close();

Example 4:

	mes("[Quest Person]");
	// The (AegisName) constant Apple comes from item_db, it is the item number 512.
	if (countitem(Apple) >= 1) {
		mes("Oh an apple, I didn't want it, I just wanted to see one");
		close();
	}
	mes("Can you please bring me an apple?");
	close();

Example 5: Using complex conditions.

	mes("[Multi Checker]");
	if ((queststarted == 1) && (countitem(Apple) >= 5)) {
		// Executed only if the quest has been started AND You have 5 apples
		mes("[Multi Checker]");
		mes("Well done you have started the quest of got me 5 apples");
		mes("Thank you");
		queststarted = 0;
		delitem(Apple, 5);
		close();
	}
	mes("Please get me 5 apples");
	queststarted = 1;
	close();

If the condition doesn't meet, it'll do the action following the else.
We can also group several actions depending on a condition, this way:

if (<condition>) {
	dothis1();
	dothis2();
} else {
	dothat1();
	dothat2();
	dothat3();
}

Example 6:

	mes("[Person Checker]");
	if ($name$ == "") {
		mes("Please tell me someone's name");
		next();
		input($name$);
		$name2$ = strcharinfo(PC_NAME);
		mes("[Person Checker]");
		mes("Thank you");
		close();
	}
	if ($name$ == strcharinfo(PC_NAME)) {
		mes("You are the person that " +$name2$+ " just mentioned");
		mes("nice to meet you");
	} else {
		mes("You are not the person that " +$name2$+ " mentioned");
	}
	$name$ = "";
	$name2$ = "";
	close();

See strcharinfo() for explanation of what this function does.

Remember that if you plan to do several actions upon the condition being
false, and you forget to use the curly braces (the { } ), the second
action will be executed regardless the output of the condition, unless of
course, you stop the execution of the script if the condition is true
(that is, in the first grouping using a return, and end or a close()).

Also, you can have multiple conditions nested or chained, and don't worry
about limits as to how many nested if you can have, there is no spoon ;).

...
if (<condition 1>) {
	dothis();
} else if (<condition 2>) {
	dotheother();
	do_that();
	end;
} else {
	do_this();
}
...

---------------------------------------

*while (<condition>) <statement or block>

This is probably the simplest and most frequently used loop structure. The
'while' statement can be interpreted as "while <condition> is true,
perform <statement>". It is a pretest loop, meaning the conditional
expression is tested before any of the statements in the body of the loop
are performed. If the condition evaluates to false, the statement(s) in
the body of the loop is/are never executed. If the condition evaluates to
true, the statement(s) are executed, then control transfers back to the
conditional expression, which is reevaluated and the cycle continues.

Multiple statements can be grouped with { }, curly braces, just like with
the 'if' statement.

Example 1:
	while (select("Yes", "No") == 2)
		mes("You picked no.");

Example 2: multiple statements
	while (select("Yes", "No") == 2) {
		mes("Why did you pick no?");
		mes("You should pick yes instead!");
	}

Example 3: counter-controlled loop
	.@i = 1;
	while (.@i <= 5) {
		mes("This line will print 5 times.");
		++.@i;
	}

Example 4: sentinel-controlled loop
	mes("Input 0 to stop");
	input(.@num);
	while (.@num != 0) {
		mes("You entered " + .@num);
		input(.@num);
	}
	close();

---------------------------------------

*for (<variable initialization>; <condition>; <variable update>) <statement or block>

Another pretest looping structure is the 'for' statement. It is considered
a specialized form of the 'while' statement, and is usually associated
with counter-controlled loops. Here are the steps of the 'for' statement:
the initialize statement is executed first and only once. The condition
test is performed. When the condition evaluates to false, the rest of the
for statement is skipped. When the condition evaluates to true, the body
of the loop is executed, then the update statement is executed (this
usually involves incrementing a variable). Then the condition is
reevaluated and the cycle continues.

Example 1:
	for (.@i = 0; .@i < 5; ++.@i)
		mes("This line will print 5 times.");

Example 2:
	mes("This will print the numbers 1 - 5.");
	for (.@i = 1; .@i <= 5; ++.@i)
		mes(.@i);

---------------------------------------

*do { <statements>; } while (<condition>)

The 'do...while' is the only post-test loop structure available in this
script language. With a post-test, the statements are executed once before
the condition is tested. When the condition is true, the statement(s) are
repeated. When the condition is false, control is transferred to the
statement following the 'do...while' loop expression.

Example 1: sentinel-controlled loop
	mes("This menu will keep appearing until you pick Cancel");
	do {
		.@choice = select("One:Two:Three:Cancel");
	} while (.@choice != 4);

Example 2: counter-controlled loop
	mes("This will countdown from 10 to 1.");
	.@i = 10;
	do {
		mes(.@i--);
	} while (.@i > 0);

---------------------------------------

*freeloop(<toggle>)

Toggling this to enabled (true) allows the script instance to bypass the
infinite loop protection, allowing your script to loop as much as it may
need. Disabling (false) may warn you if an infinite loop is detected if your
script is looping too many times.

Please note, once again, that this isn't a solution to all problems, and by
disabling this protection your Hercules server may become laggy or
unresponsive if the script it is used in is performing lenghty loop
operations.

Example:
	freeloop(true); // enable script to loop freely

	//Be aware with what you do here.
	for (.@i = 0; .@i < .@bigloop; ++.@i) {
		dothis();
		// will sleep the script for 1ms when detect an infinity loop to
		// let Hercules do what it need to do (socket, timer, process,
		// etc.)
	}

	freeloop(false); // disable

	for (.@i = 0; .@i < .@bigloop; ++.@i) {
		dothis();
		// throw an infinity loop error
	}

---------------------------------------

*setarray(<array name>[<first value>], <value>{, <value>...<value>})

This command will allow you to quickly fill up an array in one go. Check
the Kafra scripts in the distribution to see this used a lot.

	setarray(.@array[0], 100, 200, 300, 400, 500, 600);

The index of the first element of the array to alter can be omitted if
zero. For example:

	setarray(.@array, 200, 200, 200);
	setarray(.@array[1], 300, 150);

will produce:

 .@array[0] = 200
 .@array[1] = 300
 .@array[2] = 150

---------------------------------------

*cleararray(<array name>[<first value to alter>], <value>, <number of values to set>)

This command will change many array values at the same time to the same
value.

	setarray(.@array, 100, 200, 300, 400, 500, 600);
	// This will make all 6 values 0
	cleararray(.@array[0], 0, 6);
	// This will make array element 0 change to 245
	cleararray(.@array[0], 245, 1);
	// This is equivalent to the above
	cleararray(.@array, 245, 1);
	// This will make elements 1 and 2 change to 345
	cleararray(.@array[1], 345, 2);

See 'setarray'.

---------------------------------------

*copyarray(<destination array>[<first value>], <source array>[<first value>], <amount of data to copy>)

This command lets you quickly shuffle a lot of data between arrays, which
is in some cases invaluable.

	setarray(.@array, 100, 200, 300, 400, 500, 600);
	// So we have made .@array[]
	copyarray(.@array2[0], .@array[2], 2);

	// Now, .@array2[0] will be equal to .@array[2] (300) and
	// .@array2[1] will be equal to .@array[3].

So using the examples above:
 .@array[0] = 100
 .@array[1] = 200
 .@array[2] = 300
 .@array[3] = 400
 .@array[4] = 500
 .@array[5] = 600

New Array:
 .@array2[0] = 300
 .@array2[1] = 400
 .@array2[2] = 0
 .@array2[3] = 0

Notice that .@array[4] and .@array[5] won't be copied to the second array,
and it will return a 0.

---------------------------------------

*deletearray(<array name>[<first value>], <how much to delete>)

This command will delete a specified number of array elements totally from
an array, shifting all the elements beyond this towards the beginning.

	// This will delete array element 0, and move all the other array
	// elements up one place.
	deletearray(.@array[0], 1);

	// This would delete array elements numbered 1, 2 and 3, leave element 0
	// in its place, and move the other elements ups, so there are no gaps.
	deletearray(.@array[1], 3);

If the amount of items to delete is not specified, all elements of the
array starting from the specified one to the end, are deleted. If no
starting element is specified either, the the entire array will be
deleted.

	// This would delete all elements of the array starting from 2, leaving
	// element 0 and 1
	deletearray(.@array[2]);

	// This would delete all elements of the array
	deletearray(.@array);

//=====================================
---------------------------------------

*strcharinfo(<type>{, <default value>{, <GID>}})

This function will return either the name, party name or guild name for
the invoking character. Whatever it returns is determined by type.
(0) PC_NAME		- Character's name.
(1) PC_PARTY	- The name of the party they're in if any.
(2) PC_GUILD	- The name of the guild they're in if any.
(3) PC_MAP		- The name of the map the character is in.
(4) PC_CLAN   - The name of the clan they're in if any.

If <GID> is passed, it will return the value of the specified player instead
the attached player. If the player is not found, it will return
<default value>, if any, or else return an empty string.

If a character is not a member of any party or guild, an empty string will
be returned when requesting that information.

Note: Numbers can also be used in <type>, but their usage is disncouraged as
using only numbers reduces script readability

---------------------------------------

*strnpcinfo(<type>{, <default value>{, <GID>}})

This function will return the various parts of the name of the calling NPC.
Whatever it returns is determined by type.

(0) NPC_NAME	    - The NPC's display name (visible#hidden)
(1) NPC_NAME_VISIBLE - The visible part of the NPC's display name
(2) NPC_NAME_HIDDEN  - The hidden part of the NPC's display name
(3) NPC_NAME_UNIQUE  - The NPC's unique name (::name)
(4) NPC_MAP		    - The name of the map the NPC is in.

If <GID> is passed, it will return the value of the specified NPC instead of
the attached NPC. If the NPC is not found, it will return <default value>,
if any, or else return an empty string.

---------------------------------------

*charid2rid(<char id>)

This function returns the RID of the character with the given character ID.

If the character is offline or doesn't exist, 0 is returned.

---------------------------------------

*getarraysize(<array name>)

This function returns highest index of the array that is filled.
Notice that zeros and empty strings at the end of this array are not
counted towards this number.

For example:

	setarray(.@array, 100, 200, 300, 400, 500, 600);
	.@arraysize = getarraysize(.@array);

This will make .@arraysize == 6. But if you try this:

	setarray(.@array, 100, 200, 300, 400, 500, 600, 0);
	.@arraysize = getarraysize(.@array);

.@arraysize will still equal 6, even though you've set 7 values.

If you do this:

	.@array[1000] = 1;
	.@arraysize = getarraysize(.@array);

.@arraysize will be 1000, even though only one element has been set.

---------------------------------------

*getarrayindex(<array name>)

This command returns the index of the passed array. This is useful when
used in combination with getarg()

Example:

	getarrayindex(.@foo[42]) // 42

---------------------------------------

*getelementofarray(<array name>, <index>)

This command retrieves the value of the element of given array at given
index. This is equivalent to using:

	<array name>[<index>]

Also useful when passing arrays to functions or accessing another npc's
arrays:
	getelementofarray(getarg(0), <index>)
	getelementofarray(getvariableofnpc(.var, "testNPC"), <index>)

---------------------------------------

*readparam(<parameter number>{, "<player name>"})
*readparam(<parameter number>{, <account id>})

This function will return the basic stats of an invoking character,
referred to by the parameter number. Instead of a number, you can use a
parameter name if it is defined in 'doc/constants.md'.

Example parameters:

StatusPoint, BaseLevel, SkillPoint, Class, Upper, Zeny, Sex, Weight,
MaxWeight, JobLevel, BaseExp, JobExp, NextBaseExp, NextJobExp, Hp, MaxHp,
Sp, MaxSp, BaseJob, Karma, Manner, bVit, bDex, bAgi, bStr, bInt, bLuk

All of these also behave as variables, but don't expect to be able to just
'set' them - some will not work for various internal reasons.

Example 1:

	// Returns how many status points you haven't spent yet.
	mes("Unused status points: "+readparam(9)); // [!]

Using this particular information as a function call is not required.
Typing this will return the same result:

	mes("Unused status points: "+StatusPoint);

Example 2:

You can also use this command to get stat values.

	if (readparam(bVit) > 77)
		mes("Only people with over 77 Vit are reading this!");

Example 3:

	// Display your current weight
	mes("Your current weight is "+ (Weight/10) + "/" + (MaxWeight/10));

---------------------------------------

*setparam(<parameter number>, <value>{, "<player name>"})
*setparam(<parameter number>, <value>{, <account id>})

Sets a parameter on the given player. See readparam() for more info about
parameters. Keep in mind that not all read-able parameters are also set-able.

Parameters that can be modified include:

StatusPoint, BaseLevel, SkillPoint, Zeny, Sex, Weight, MaxWeight, JobLevel,
BaseExp, JobExp, Hp, MaxHp, Sp, MaxSp, Karma, Manner, Fame, bVit, bDex, bAgi,
bStr, bInt, bLuk


---------------------------------------

*getcharid(<type>{, "<character name>"})

This function will return a unique ID number of the invoking character,
or, if a character name is specified, of that player.

Type is the kind of associated ID number required:

(0) CHAR_ID_CHAR - Character ID number.
(1) CHAR_ID_PARTY - Party ID number.
(2) CHAR_ID_GUILD - Guild ID number.
(3) CHAR_ID_ACCOUNT - Account ID number.
(4) CHAR_ID_BG - Battle ground ID
(5) CHAR_ID_CLAN - Clan ID number.

For most purposes other than printing it, a number is better to have than
a name (people do horrifying things to their character names).

If the character is not in a party or not in a guild, the function will
return 0 if guild or party number is requested. If a name is specified and
the character is not found, 0 is returned.

If getcharid(CHAR_ID_CHAR) returns a zero, the script got called not by a character
and doesn't have an attached RID. Note that this will cause the map server
to print "player not attached!" error messages, so it is preferred to use
playerattached() to check for the character attached to the script.

	if (getcharid(CHAR_ID_GUILD) == 0)
		mes("Only members of a guild are allowed here!");

---------------------------------------

*getnpcid({"<npc name>"})

Retrieves IDs of the currently invoked NPC. If a unique npc name is given,
IDs of that NPC are retrieved instead.

If the NPC does not exist, 0 is returned.

---------------------------------------

*getchildid()
*getmotherid()
*getfatherid()

These functions return the character ID of the attached player's child,
mother, mother, or father, respectively. It returns 0 if no ID is found.

	if (getmotherid() != 0)
		mes("Your mother's ID is: "+getmotherid());

---------------------------------------

*ispartneron()

This function returns true if the invoking character's marriage partner
is currently online and false if they are not or if the character has no
partner.

---------------------------------------

*getpartnerid()

This function returns the character ID of the invoking character's
marriage partner, if any. If the invoking character is not married, it
will return 0, which is a quick way to see if they are married:

	if (getpartnerid() == 0)
		mes("I'm not going to be your girlfriend!");
	else
		mes("You're married already!");

---------------------------------------

*getpartyname(<party id>)

This function will return the name of a party that has the specified ID
number. If there is no such party ID, "null" will be returned.

Lets say the ID of a party was saved as a global variable:

	// This would return the name of the party from the ID stored in a
	// variable
	mes("You're in the '"+getpartyname($@var)+"' party, I know!");

---------------------------------------

*getpartymember(<party id>{, <type>})

This command will find all members of a specified party and returns their
names (or character id or account id depending on the value of "type")
into an array of temporary global variables. There's actually quite a few
commands like this which will fill a special variable with data upon
execution and not do anything else.

Upon executing this,

$@partymembername$[] is a global temporary string array which contains all
                     the names of these party members.
                     (only set when type is 0 or not specified)

$@partymembercid[]   is a global temporary number array which contains the
                     character id of these party members.
                     (only set when type is 1)

$@partymemberaid[]   is a global temporary number array which contains the
                     account id of these party members.
                     (only set when type is 2)

$@partymembercount   is the number of party members that were found.

The party members will (apparently) be found regardless of whether they
are online or offline. Note that the names come in no particular order.

Be sure to use $@partymembercount to go through this array, and not
'getarraysize', because it is not cleared between runs of 'getpartymember'.
If someone with 7 party members invokes this script, the array would have
7 elements. But if another person calls up the NPC, and he has a party of
5, the server will not clear the array for you, overwriting the values
instead. So in addition to returning the 5 member names, the 6th and 7th
elements from the last call remain, and you will get 5+2 members, of which
the last 2 don't belong to the new guy's party. $@partymembercount will
always contain the correct number, (5) unlike 'getarraysize()' which will
return 7 in this case.

Example 1: list party member names

	// get the party member names
	getpartymember(getcharid(CHAR_ID_PARTY), 0);

	// It's a good idea to copy the global temporary $@partymember*****
	// variables to your own scope variables because if you have pauses in
	// this script (sleep, sleep2, next, close2, input, menu, select, or
	// prompt), another player could click this NPC, trigger
	// 'getpartymember', and overwrite the $@partymember***** variables.
	.@count = $@partymembercount;
	copyarray(.@name$[0], $@partymembername$[0], $@partymembercount);

	// list the party member names
	for (.@i = 0; .@i < .@count; ++.@i) {
		mes((.@i +1) + ". ^0000FF" + .@name$[.@i] + "^000000");
	}
	close();


Example 2: check party count (with a next() pause), before warping to event

	.register_num = 5; // How many party members are required?

	// get the charID and accountID of character's party members
	getpartymember(getcharid(CHAR_ID_PARTY), 1);
	getpartymember(getcharid(CHAR_ID_PARTY), 2);

	if ($@partymembercount != .register_num) {
		mes("Please form a party of "+ .register_num +" to continue");
		close();
	}

	// loop through both and use 'isloggedin' to count online party members
	for (.@i = 0; .@i < $@partymembercount; ++.@i)
		if (isloggedin($@partymemberaid[.@i], $@partymembercid[.@i]))
			.@count_online++;
	// We search accountID & charID because a single party can have
	// multiple characters from the same account. Without searching
	// through the charID, if a player has 2 characters from the same
	// account inside the party but only 1 char online, it would count
	// their online char twice.

	if (.@count_online != .register_num) {
		mes("All your party members must be online to continue");
		close();
	}

	// copy the array to prevent players cheating the system
	copyarray(.@partymembercid, $@partymembercid, .register_num);

	// When a script hits a next, menu, sleep or input that pauses the
	// script, players can invite or /leave and make changes in their
	// party. To prevent this, we call getpartymember again and compare
	// with the original values.

	getpartymember(getcharid(CHAR_ID_PARTY), 1);
	if ($@partymembercount != .register_num) {
		mes("You've made changes to your party !");
		close();
	}
	for (.@i = 0; .@i < $@partymembercount; ++.@i) {

*getpartyleader(<party id>{, <type>})

This function returns some information about the given party-id's leader.
When type is omitted, the default information retrieved is the leader's
name. Possible types are:

	1: Leader account id
	2: Leader character id
	3: Leader's class
	4: Leader's current map name
	5: Leader's current level as stored on the party structure (may not be
	   current level if leader leveled up recently).

If retrieval fails (leader not found or party does not exist), this
function returns "null" instead of the character name, and -1 for the
other types.

---------------------------------------

*getlook(<type>)

This function will return the number for the current character look value
specified by type. See 'setlook' for valid look types.

This can be used to make a certain script behave differently for
characters dressed in black. :)

---------------------------------------

*getsavepoint(<information type>)

This function will return information about the invoking character's save
point. You can use it to let a character swap between several recorded
save points. Available information types are:

 0 - Map name (a string)
 1 - X coordinate
 2 - Y coordinate

---------------------------------------

*getcharip({"<character name>"})
*getcharip({<account id>})
*getcharip({<character id>})

This function will return the IP address of the invoking character, or, if
a player is specified, of that character. A blank string is returned if no
player is attached.

Examples:

// Outputs IP address of attached player.
	mes("Your IP: " + getcharip());

// Outputs IP address of character "Silver".
	mes("Silver's IP: " + getcharip("Silver"));

---------------------------------------

*sit({"<character name>"})
*stand({"<character name>"})

This function will force a character to sit/stand if it is standing/sitting.
If no player is specified, the attached player will be used.

---------------------------------------

*issit({"<character name>"})

This function will return a number depending on the character's sitting state.
If the character is sitting, it will return true, otherwise (standing) it will return false.
In case no player is specified, the function will return the state of the attached player.

---------------------------------------

2.1 - Item-Related Commands
//=====================================
---------------------------------------

*getequipid(<equipment slot>)

This function returns the item ID of the item equipped in the equipment
slot specified on the invoking character. If nothing is equipped there, it
returns -1. Valid equipment slots are:

EQI_HEAD_TOP (1)          - Upper head gear
EQI_ARMOR (2)             - Armor (Where you keep your Jackets and Robes)
EQI_HAND_L (3)            - What is in your Left hand.
EQI_HAND_R (4)            - What is in your Right hand.
EQI_GARMENT (5)           - The garment slot (Mufflers, Hoods, Manteaus)
EQI_SHOES (6)             - What foot gear the player has on.
EQI_ACC_L (7)             - Accessory 1.
EQI_ACC_R (8)             - Accessory 2.
EQI_HEAD_MID (9)          - Middle Headgear (masks and glasses)
EQI_HEAD_LOW (10)         - Lower Headgear (beards, some masks)
EQI_COSTUME_HEAD_LOW (11) - Lower Costume Headgear
EQI_COSTUME_HEAD_MID (12) - Middle Costume Headgear
EQI_COSTUME_HEAD_TOP (13) - Upper Costume Headgear
EQI_COSTUME_GARMENT (14)  - Costume Garment
EQI_SHADOW_ARMOR (15)     - Shadow Armor
EQI_SHADOW_WEAPON (16)    - Shadow Weapon
EQI_SHADOW_SHIELD (17)    - Shadow Shield
EQI_SHADOW_SHOES (18)     - Shadow Shoes
EQI_SHADOW_ACC_R (19)     - Shadow Accessory 2
EQI_SHADOW_ACC_L (20)     - Shadow Accessory 1

Notice that a few items occupy several equipment slots, and if the
character is wearing such an item, 'getequipid' will return it's ID number
for either slot.

Can be used to check if you have something equipped, or if you haven't got
something equipped:

	if (getequipid(EQI_HEAD_TOP) == Tiara) {
		mes("What a lovely Tiara you have on");
		close();
	}
	mes("Come back when you have a Tiara on");
	close();

You can also use it to make sure people don't pass a point before removing
an item totally from them. Let's say you don't want people to wear Legion
Plate armor, but also don't want them to equip if after the check, you
would do this:

	if (getequipid(EQI_ARMOR) == Full_Plate_Armor || getequipid(EQI_ARMOR) == Full_Plate_Armor_) {
		mes("You are wearing some Legion Plate Armor, please drop that in your stash before continuing");
		close();
	}
	if (countitem(Full_Plate_Armor) > 0 || countitem(Full_Plate_Armor_) > 0) {
		mes("You have some Legion Plate Armor in your inventory, please drop that in your stash before continuing");
		close();
	}
	mes("I will lets you pass");
	close2();
	warp("place", 50, 50);
	end;

---------------------------------------

*getequipname(<equipment slot>)

Returns the jname of the item equipped in the specified equipment slot on
the invoking character, or an empty string if nothing is equipped in that
position.
Does the same thing as getitemname(getequipid()). Useful for an NPC to
state what your are wearing, or maybe saving as a string variable.
See getequipid() for a full list of valid equipment slots.

	if (getequipid(EQI_HEAD_TOP) != 0)
		mes("So you are wearing a "+getequipname(EQI_HEAD_TOP)+" on your head");
	else
		mes("You are not wearing a head gear");

---------------------------------------

*getitemname(<item id>)

Given the database ID number of an item, this function will return the
text stored in the 'japanese name' field (which, in Hercules, stores an
English name the players would normally see on screen).
Return "null" if no such item exist.

---------------------------------------

*getbrokenid(<number>)

This function will search the invoking character's inventory for any
broken items, and will return their item ID numbers. Since the character
may have several broken items, 1 given as an argument will return the
first one found, 2 will return the second one, etc. Will return 0 if no
such item is found.

	// Let's see if they have anything broken:
	if (getbrokenid(1) == 0)
		mes("You don't have anything broken, quit bothering me.");
	else // They do, so let's print the name of the first broken item:
		mes("Oh, I see you have a broken "+getitemname(getbrokenid(1))+" here!");

---------------------------------------

*getbrokencount()

This function will return the total amount of broken equipment on the
invoking character.

---------------------------------------

*getequipisequiped(<equipment slot>)

This functions will return 1 if there is an equipment placed on the
specified equipment slot and 0 otherwise. For a list of equipment slots
see 'getequipid'. Function originally used by the refining NPCs:

	if (getequipisequiped(EQI_HEAD_TOP)) {
		mes("[Refiner]");
		mes("That's a fine hat you are wearing there...");
		close();
	}
	mes("[Refiner]");
	mes("Do you want me to refine your dumb head?");
	close();

---------------------------------------

*getequipisenableref(<equipment slot>)

Will return true if the item equipped on the invoking character in the
specified equipment slot is refinable, and false if it isn't. For a list
of equipment slots see getequipid().

	if (getequipisenableref(EQI_HEAD_TOP)) {
		mes("[Refiner]");
		mes("Ok I can refine this");
		close();
	}
	mes("[Refiner]");
	mes("I can't refine this hat!...");
	close();

---------------------------------------

*getequiprefinerycnt(<equipment slot>{, <equipment slot>{, <equipment slot>}})

Returns the total of refine of item equipped in the equipment slots.
For a list of equipment slots, see 'getequipid'.

For example:
	if (getequiprefinerycnt(EQI_HEAD_TOP) > 10) {
		mes("You equipped a headgear (top) with above 10 refine.");
	}

For example:
	if (getequiprefinerycnt(EQI_ARMOR, EQI_SHOES) > 20) {
		mes("Total refine of Armor and Shoes exceed 20.");
	}

---------------------------------------

*getequipweaponlv(<equipment slot>)

This function returns the weapon level for the weapon equipped in the
specified equipment slot on the invoking character. For a list of
equipment slots see 'getequipid'.

Only EQI_HAND_L and EQI_HAND_R normally make sense, since only weapons
have a weapon level. You can, however, probably, use this field for other
equippable custom items as a flag or something.

If no item is equipped in this slot, or if it doesn't have a weapon level
according to the database, 0 will be returned.

Examples:

// Right hand can only contain a weapon.
	switch (getequipweaponlv(EQI_HAND_R)) {
	case 1:
		mes("You are holding a lvl 1 weapon.");
		break;
	case 2:
		mes("You are holding a lvl 2 weapon.");
		break;
	case 3:
		mes("You are holding a lvl 3 weapon.");
		break;
	case 4:
		mes("You are holding a lvl 4 weapon.");
		break;
	case 5:
		mes("You are holding a lvl 5 weapon, hm, must be a custom design...");
		break;
	default:
		mes("Seems you don't have a weapon on.");
		break;
	}

// Left hand can hold either a weapon or shield.
	if (getequipid(EQI_HAND_R) == 0) {
		mes("Seems you have nothing equipped here.");
		close();
	}
	switch (getequipweaponlv(EQI_HAND_L)) {
	case 0:
		mes("You are holding a shield, so it doesn't have a level.");
		break;
	case 1:
		mes("You are holding a lvl 1 weapon.");
		break;
	case 2:
		mes("You are holding a lvl 2 weapon.");
		break;
	case 3:
		mes("You are holding a lvl 3 weapon.");
		break;
	case 4:
		mes("You are holding a lvl 4 weapon.");
		break;
	case 5:
		mes("You are holding a lvl 5 weapon, hm, must be a custom design...");
		break;
	}

---------------------------------------

*getequippercentrefinery(<equipment slot>{, <type>})

This function calculates and returns the percent value chance to
successfully refine the item found in the specified equipment slot of the
invoking character by +1. Refine rates are defined in the db/<re/pre-re>/refine_db.conf
files. For a list of equipment slots see getequipid().

These values can be displayed for the player to see, or used to calculate
the random change of a refine succeeding or failing and then going through
with it (which is what the official NPC refinery scripts use it for).

Refine Chance Type Constants -
REFINE_CHANCE_TYPE_NORMAL: 0        (Normal Ores)
REFINE_CHANCE_TYPE_ENRICHED: 1      (Enriched Ores)
REFINE_CHANCE_TYPE_E_NORMAL: 2      (Event Normal Ores)
REFINE_CHANCE_TYPE_E_ENRICHED: 3    (Event Enriched Ores)

Refine rate information -
Normal Ores: http://ro.gnjoy.com/news/probability/View.asp?category=4&seq=1941553&curpage=1
Enriched Ores:  http://ro.gnjoy.com/news/probability/View.asp?category=4&seq=1941565&curpage=1
Event Normal Ores: http://ro.gnjoy.com/news/probability/View.asp?category=4&seq=1941558&curpage=1
Event Enriched Ores: http://ro.gnjoy.com/news/probability/View.asp?category=4&seq=1941567&curpage=1

// This will find a random number from 0 - 99 and if that is equal to or
// more than the value recovered by this command it will show a message
	if (getequippercentrefinery(EQI_HAND_L, REFINE_CHANCE_TYPE_NORMAL) <= rand(100))
		mes("Aww");

---------------------------------------

*getareadropitem("<map name>", <x1>, <y1>, <x2>, <y2>, <item>)

This function will count all the items with the specified ID number lying
on the ground on the specified map within the x1/y1-x2/y2 square on it and
return that number.

This is the only function around where a parameter may be either a string
or a number! If it's a number, it means that only the items with that item
ID number will be counted. If it is a string, it is assumed to mean the
'english name' field from the item database. If you give it an empty
string, or something that isn't found from the item database, it will
count items number 512 (Apple).

---------------------------------------

*getequipcardcnt(<equipment slot>)

This function will return the number of cards that have been compounded
onto a specific equipped item for the invoking character. See 'getequipid'
for a list of possible equipment slots.

---------------------------------------

*getinventorylist()

This command sets a bunch of arrays with a complete list of whatever the
invoking character has in its inventory, including all the data needed to
recreate these items perfectly if they are destroyed. Here's what you get:

@inventorylist_id[]            - array of item ids.
@inventorylist_idx[]           - array of item inventory index.
@inventorylist_amount[]        - their corresponding item amounts.
@inventorylist_equip[]         - will return the slot the item is equipped on, if at all.
@inventorylist_refine[]        - for how much it is refined.
@inventorylist_identify[]      - whether it is identified.
@inventorylist_attribute[]     - whether it is broken.
@inventorylist_card1[]         - These four arrays contain card data for the items.
@inventorylist_card2[]           These data slots are also used to store names inscribed
@inventorylist_card3[]           on the items, so you can explicitly check if the character 
@inventorylist_card4[]           owns an item made by a specific craftsman.
@inventorylist_expire[]        - expire time (Unix time stamp). 0 means never expires.
@inventorylist_bound[]         - whether it is an account bounded item or not.
@inventorylist_favorite[]      - whether it is favorite (inside favorite tab) or not.
@inventorylist_opt_id1~5[]     - array of random option id.
@inventorylist_opt_val1~5[]    - array of random option val.
@inventorylist_opt_param1~5[]  - array of random option param.
@inventorylist_count           - the number of items in these lists.

This could be handy to save/restore a character's inventory, since no
other command returns such a complete set of data, and could also be the
only way to correctly handle an NPC trader for carded and named items who
could resell them - since NPC objects cannot own items, so they have to
store item data in variables and recreate the items.

Notice that the variables this command generates are all temporary,
attached to the character, and integer.

Be sure to use @inventorylist_count to go through these arrays, and not
getarraysize(), because the arrays are not automatically cleared between
runs of getinventorylist().

---------------------------------------

*getcartinventorylist()

This command sets a bunch of arrays with a complete list of whatever the
invoking character has in its cart_inventory, including all the data needed to
recreate these items perfectly if they are destroyed. Here's what you get:

@cartinventorylist_id[]        - array of item ids.
@cartinventorylist_amount[]    - their corresponding item amounts.
@cartinventorylist_refine[]    - for how much it is refined.
@cartinventorylist_identify[]  - whether it is identified.
@cartinventorylist_attribute[] - whether it is broken.
@cartinventorylist_card1[]     - These four arrays contain card data for the items.
@cartinventorylist_card2[]       These data slots are also used to store names inscribed on the items,
@cartinventorylist_card3[]       so you can explicitly check if the character owns an item
@cartinventorylist_card4[]       made by a specific craftsman.
@cartinventorylist_expire[]    - expire time (Unix time stamp). 0 means never expires.
@cartinventorylist_bound       - whether it is an account bound item or not.
@inventorylist_opt_id1~5[]     - array of random option id.
@inventorylist_opt_val1~5[]    - array of random option val.
@inventorylist_opt_param1~5[]  - array of random option param.
@cartinventorylist_count       - the number of items in these lists.

This could be handy to save/restore a character's cart_inventory, since no
other command returns such a complete set of data, and could also be the
only way to correctly handle an NPC trader for carded and named items who
could resell them - since NPC objects cannot own items, so they have to
store item data in variables and recreate the items.

Notice that the variables this command generates are all temporary,
attached to the character, and integer.

Be sure to use @cartinventorylist_count to go through these arrays, and not
getarraysize(), because the arrays are not automatically cleared between
runs of getcartinventorylist().

---------------------------------------

---------------------------------------

*getrefine()

This function will return the refine count of the equipment from which

*getitemslots(<item ID>)

This function will look up the item with the specified ID number in the
database and return the number of slots this kind of items has - 0 if they
are not slotted. It will also be 0 for all non-equippable items,
naturally, unless someone messed up the item database. It will return -1
if there is no such item.

Example:

//.@slots now has the amount of slots of the item with ID 1205.

Gets the option information of an equipment.

<equipment_index> For a list of equipment indexes see getequipid().
<option_slot> can range from 1 to MAX_ITEM_OPTIONS
<type> can be IT_OPT_INDEX (the ID of the option bonus, @see "Id" or "Name" in db/item_options.conf)
       or IT_OPT_VALUE (the value of the bonus script of the equipment, @see "Script" in db_item_options.conf).

returns the value of the slot if exists or -1 for invalid slot, type or slots.

---------------------------------------

*setequipoption(<equip_index>,<slot>,<opt_index>,<value>);

---------------------------------------

*identifyidx(<Inventory Index>)

This will identify item at attached player's <Inventory Index> inventory index.

Returns true if the item was identified, false otherwise.
Note: If the item was already identified, it returns false.

*getmapxy("<variable for map name>", <variable for x>, <variable for y>, <type>{, "<search parameter>"})

This function will locate a character object, NPC object or pet's
coordinates and place their coordinates into the variables specified when
calling it. It will return 0 if the search was successful, and -1 if the
parameters given were not variables or the search was not successful.

Type is the type of object to search for:

	UNITTYPE_PC   - Character object
	UNITTYPE_NPC  - NPC object
	UNITTYPE_PET  - Pet object
	UNITTYPE_MOB  - Monster object
	UNITTYPE_HOM  - Homunculus object
	UNITTYPE_MER  - Mercenary object
	UNITTYPE_ELEM - Elemental object

To look for a monster object, monster GID is required. The function will
always return -1 when search using string.

The search parameter is optional. If it is not specified, the location of the
invoking character will always be returned for UNITTYPE_PC, the location of the
NPC running this function for UNITTYPE_NPC. If a search parameter is specified,
for UNITTYPE_PC and UNITTYPE_NPC, the character or NPC with the specified name
or GID will be located.

If type is UNITTYPE_PET, UNITTYPE_HOM, UNITTYPE_MER or UNITTYPE_ELEM the search
will locate the owner's pet/homun/mercenary/elementals if the search parameter
is not provided. It will NOT locate these object by name, but can be done if GID
is provided.

What a mess. Example, a working and tested one now:

	prontera,164,301,3%TAB%script%TAB%Meh%TAB%730,{
		mes("My name is Meh. I'm here so that Nyah can find me.");
		close();
	}

	prontera,164,299,3%TAB%script%TAB%Nyah%TAB%730,{
		mes("My name is Nyah.");
		mes("I will now search for Meh all across the world!");
		if (getmapxy(.@mapname$, .@mapx, .@mapy, UNITTYPE_NPC, "Meh") != 0) {
			mes("I can't seem to find Meh anywhere!");
			close();
		}
		mes("And I found him on map "+.@mapname$+" at X:"+.@mapx+" Y:"+.@mapy+" !");
		close();
	}

Notice that NPC objects disabled with disablenpc() will still be located.

---------------------------------------

*getmapinfo(<info>{, "<map name>"})
*getmapinfo(<info>{, <map id>})

This command returns various information about a specific map. If the second
argument is omitted, it will try to use the map of the attached NPC, or the
map of the attached player if the NPC can't be found.

Valid <info> are:
	MAPINFO_NAME         name of the map
	MAPINFO_ID           numeric ID of the map
	MAPINFO_ZONE         name of the zone used by the map
	MAPINFO_SIZE_X       width of the map (cells on the x axis)
	MAPINFO_SIZE_Y       height of the map (cells on the y axis)
	MAPINFO_NPC_COUNT    total number of NPC in the map

Examples:
	getmapinfo(MAPINFO_ID, "map name"); // ID from name
	getmapinfo(MAPINFO_NAME, 3); // name from ID
	getmapinfo(MAPINFO_ZONE); // zone, ie Normal, PvP, Jail, ...

---------------------------------------

*getunits(<type>, <variable>, <limit>{, "<map>"{, <x1>, <y1>, <x2>, <y2>}})

This function searches a whole map or area for units and adds their GID to
the provided <variable> array. It filters units by <type> and stops searching
after <limit> units have been found. Set <limit> to false (0) if you wish to
disable the limit altogether. If <map> is omitted, this command will search
on the whole server (slow). Returns the number of units added to the array.

Type is the type of unit to search for:

	BL_PC    - Character object
	BL_MOB   - Monster object
	BL_PET   - Pet object
	BL_HOM   - Homunculus object
	BL_MER   - Mercenary object
	BL_ITEM  - Item object (item drops)
	BL_SKILL - Skill object (skill fx & sfx)
	BL_NPC   - NPC object
	BL_CHAT  - Chat object
	BL_ELEM  - Elemental object
	BL_CHAR  - Shorthand for (BL_PC|BL_MOB|BL_HOM|BL_MER|BL_ELEM)
	BL_ALL   - Any kind of object

** Do NOT use UNITTYPE_ constants here, they have different values.

** If battle_config.dynamic_mobs is enabled and no player has entered the map
   yet, the mobs will not have spawned in the map yet, so getunits() will be
   unable to find them when searching for BL_MOB.

Example:

	.@count = getunits((BL_PC | BL_NPC), .@units, false, "prontera");

The above example would search the map "prontera" for all PC and NPC units and
add them to the .@units array, while setting .@count to the amount of units
added to the array (useful in for() loops).

---------------------------------------

*getgmlevel()

This function will return the (GM) level of player group the account to
which the invoking character belongs. If this is somehow executed from a
console command, 99 will be returned, and 0 will be returned if the
account has no GM level.

This allows you to make NPC's only accessible for certain GM levels, or
behave specially when talked to by GMs.

	if (getgmlevel() > 0)
		mes("What is your command, your godhood?");
	if (getgmlevel() < 99)
		end;

---------------------------------------

*setgroupid(<new group id>{, "<character name>"})
*setgroupid(<new group id>{, <account id>})

This function will temporary adjust the id of player group the account to which the
player specified if the new group id is available.
Return true if successful, otherwise it will return false.

---------------------------------------

*getgroupid({<account id>})

This command returns the id of the group of the attached or specified player.
If the player is not found, returns -1.

---------------------------------------

*gettimetick(<type>)

Valid types are :
	0 - server's tick (milleseconds), unsigned int, loops every ~25 days
	1 - time since the start of the current day in seconds
	2 - UNIX epoch time (number of seconds elapsed since 1st of January 1970)

---------------------------------------

*gettime(<type>)

This function returns specified information about the current system time.

Valid types:
	1 - GETTIME_SECOND     - Seconds (of a minute)
	2 - GETTIME_MINUTE     - Minutes (of an hour)
	3 - GETTIME_HOUR       - Hour (of a day)
	4 - GETTIME_WEEKDAY    - Week day (0 for Sunday, 6 is Saturday)
	                       - Additional: SUNDAY, MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY, SATURDAY
	5 - GETTIME_DAYOFMONTH - Day of the month.
	6 - GETTIME_MONTH      - Number of the month.
	                       - Additional: JANUARY, FEBRUARY, MARCH, APRIL, MAY, JUNE, JULY, AUGUST, SEPTEMBER, OCTOBER, NOVEMBER, DECEMBER
	7 - GETTIME_YEAR       - Year
	8 - GETTIME_DAYOFYEAR  - Day of the year.

It will only return numbers based on types.
Example :
	if (gettime(GETTIME_WEEKDAY) == SATURDAY) {
		mes("It's a Saturday. I don't work on Saturdays.");
	} else if (gettime(GETTIME_MONTH) == JANUARY) {
		mes("It's January. I don't work on January.");
	} else if (gettime(GETTIME_MONTH) == OCTOBER && gettime(GETTIME_DAYOFMONTH) == 31) {
		mes("It's Halloween.");
	}

---------------------------------------

*getcalendartime(<hour>, <minute>{, <day of month>{, <day of week>}})

This function returns the timestamp of the next ocurrence of given time.

Day of Month specifies a day between 1 and 31 in the future, by default its value is -1 (don't use).
Day of Week specifies a day in the week and its valid values are:
	0 - SUNDAY
	1 - MONDAY
	2 - TUESDAY
	3 - WEDNESDAY
	4 - THURSDAY
	5 - FRIDAY
	6 - SATURDAY

In order to use Day of Week, you must use Day of Month as -1.
If for some reason the command fails, it'll return -1.

Examples :
	getcalendartime(19, 00); // Next 7 pm
	getcalendartime(19, 00, 6); // Next day 6 of the month, at 7pm
	getcalendartime(19, 10, -1, 1); // Next Monday, at 7:10pm

---------------------------------------

*gettimestr(<format string>, <max length>{, <timestamp>})

This function will return a string containing time data as specified by
the format string.

This uses the C function 'strftime', which obeys special format
characters. For a full description see, for example, the description of
'strftime' at http://www.delorie.com/gnu/docs/glibc/libc_437.html
All the format characters given in there should properly work.
Max length is the maximum length of a time string to generate.

The example given in Hercules sample scripts works like this:

	mes(gettimestr("%Y-%m/%d %H:%M:%S", 21));
	mes(gettimestr("%Y-%m/%d %H:%M:%S", 21, getcalendartime(0, 0)));

This will print a full date and time like 'YYYY-MM/DD HH:MM:SS'.

---------------------------------------

*getusers(<type>)

This function will return a number of users on a map or the whole server.
What it returns is specified by Type.

Type can be one of the following values, which control what is returned:

	0 - Count of all characters on the map of the invoking character.
	1 - Count of all characters in the entire server.
	8 - Count of all characters on the map of the NPC the script is
		running in.

---------------------------------------

*getmapusers("<map name>")

This function will return the number of users currently located on the
specified map.

Currently being used in the PVP scripts to check if a PVP room is full of
not, if the number returned it equal to the maximum allowed it will not
let you enter.

Return -1 if the map name is invalid.

---------------------------------------

*getareausers({"<map name>", }{<x1>, <y1>, <x2>, <y2>})
*getareausers({"<map name>", }{<radius>})

This function will return the count of connected characters which are
located within the specified area. Area can be x1/y1-x2/y2 square,
or radius from npc position. If map name missing, used attached player map.

This is useful for maps that are split into many buildings, such as all
the "*_in" maps, due to all the shops and houses.

Examples:
	// return players in area npc area on current map.
	.@num = getareausers();
	// return players in square (1, 1) - (10, 10)
	.@num = "players: " + getareausers(1, 1, 10, 10);

---------------------------------------

*getusersname();

This command will give the invoking character a list of names of the
connected characters (including themselves) into an NPC script message
window (see 'mes') paging it by 10 names as if with the next() command.

You need to put a 'close' after that yourself.

---------------------------------------
//=====================================
2.2 - Guild-Related Commands
//=====================================
---------------------------------------

*getguildinfo(<info type>{, <guild id>})
*getguildinfo(<info type>{, "<guild name>"})

This command returns misc info about the guild of the attached player. If a
guild id or guild name is specified it will be used instead. If the target guild
does not exist it returns an empty string or -1 depending on whether a string
or an integer was requested.

Valid <info type> are:
	GUILDINFO_NAME          - guild name
	GUILDINFO_ID            - guild id
	GUILDINFO_LEVEL         - current level
	GUILDINFO_EXP           - current exp
	GUILDINFO_NEXT_EXP      - exp required to reach the next level
	GUILDINFO_SKILL_POINTS  - available skill points
	GUILDINFO_ONLINE        - number of online members
	GUILDINFO_AV_LEVEL      - average member level
	GUILDINFO_MAX_MEMBERS   - guild capacity
	GUILDINFO_MASTER_NAME   - name of the guild master
	GUILDINFO_MASTER_CID    - char id of the guild master

Example:
	getguildinfo(GUILDINFO_MASTER_NAME, getcharid(CHAR_ID_GUILD, "Haru"))

---------------------------------------

*getguildname(<guild id>)

    @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
    @ /!\ This command is deprecated @
    @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

This function returns a guild's name given an ID number. If there is no
such guild, "null" will be returned;

	// Would print whatever guild 10007 name is.
	mes("The guild "+getguildname(10007)+" are all nice people.");

	// This will do the same as above:
	.@var = 10007;
	mes("We have some friends in "+getguildname(.@var)+", you know.");

This is used all over the WoE controlling scripts. You could also use it
for a guild-based event.

This command is deprecated and it should not be used in new scripts, as it is
likely to be removed at a later time. Please use getguildinfo instead:
	getguildinfo(GUILDINFO_NAME, <guild id>)

---------------------------------------

*getguildmaster(<guild id>)

    @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
    @ /!\ This command is deprecated @
    @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

This function return the name of the master of the guild which has the
specified ID number. If there is no such guild, "null" will be returned.

// Would return the guild master of guild 10007, whatever that might be.
	mes(getguildmaster(10007)+" runs "+getguildname(10007));

Can be used to check if the character is the guild master of the specified
guild.

Maybe you want to make a room only guild masters can enter:

	.@GID = getcharid(CHAR_ID_GUILD);
	if (.@GID == 0) {
		mes("Sorry you are not in a guild");
		close();
	}
	if (strcharinfo(PC_NAME) == getguildmaster(.@GID)) {
		mes("Welcome guild master of "+getguildname(.@GID));
		close();
	}
	mes("Sorry you don't own the guild you are in");
	close();

This command is deprecated and it should not be used in new scripts, as it is
likely to be removed at a later time. Please use getguildinfo instead:
	getguildinfo(GUILDINFO_MASTER_NAME, <guild id>)

---------------------------------------

*getguildmasterid(<guild id>)

    @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
    @ /!\ This command is deprecated @
    @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

This function will return the character ID number of the guild master of
the guild specified by the ID. 0 if the character is not a guild master of
any guild.

This command is deprecated and it should not be used in new scripts, as it is
likely to be removed at a later time. Please use getguildinfo instead:
	getguildinfo(GUILDINFO_MASTER_CID, <guild id>)

---------------------------------------

*getcastlename("<map name>")

This function returns the name of the castle when given the map name for
that castle. The data is read from 'db/castle_db.txt'.

---------------------------------------

*getcastledata("<map name>", <type of data>)
*setcastledata("<map name>", <type of data>, <value>);

This function returns the castle ownership information for the castle
referred to by its map name. Castle information is stored in
`guild_castle` SQL table.

Types of data correspond to `guild_castle` table columns:

 1 - `guild_id`   - Guild ID.
 2 - `economy`    - Castle Economy score.
 3 - `defense`    - Castle Defense score.
 4 - `triggerE`   - Number of times the economy was invested in today.
 5 - `triggerD`   - Number of times the defense was invested in today.
 6 - `nextTime`   - unused
 7 - `payTime`    - unused
 8 - `createTime` - unused
 9 - `visibleC`   - Is 1 if a Kafra was hired for this castle, 0 otherwise.
10 - `visibleG0`  - Is 1 if the 1st guardian is present (Soldier Guardian)
11 - `visibleG1`  - Is 1 if the 2nd guardian is present (Soldier Guardian)
12 - `visibleG2`  - Is 1 if the 3rd guardian is present (Soldier Guardian)
13 - `visibleG3`  - Is 1 if the 4th guardian is present (Archer Guardian)
14 - `visibleG4`  - Is 1 if the 5th guardian is present (Archer Guardian)
15 - `visibleG5`  - Is 1 if the 6th guardian is present (Knight Guardian)
16 - `visibleG6`  - Is 1 if the 7th guardian is present (Knight Guardian)
17 - `visibleG7`  - Is 1 if the 8th guardian is present (Knight Guardian)

All types of data have their meaning determined by War of Emperium
scripts, with exception of:
 - `guild_id` that is always the ID of the guild that owns the castle,
 - `defense` that is used in Guardians & Emperium HP calculations,
 - `visibleG` that is always considered to hold guardian presence bits.

The setcastledata() command will behave identically, but instead of
returning values for the specified types of accessible data, it will alter
them and cause them to be sent to the char-server for storage.

Changing Guild ID or Castle Defense will trigger additional actions, like
recalculating guardians' HP.

---------------------------------------

*getgdskilllv(<guild id>, <skill id>)
*getgdskilllv(<guild id>, "<skill name>")

This function returns the level of the skill <skill id> of the guild
<guild id>.
If the guild does not have that skill, 0 is returned.
If the guild does not exist, -1 is returned.
Refer to 'db/(pre-)re/skill_db.txt' for the full list of skills.
GD_* are guild skills

---------------------------------------

*requestguildinfo(<guild id>{, "<event label>"});

This command requests the guild data from the char server and merrily
continues with the execution. Whenever the guild information becomes
available (which happens instantly if the guild information is already in
memory, or later, if it isn't and the map server has to wait for the char
server to reply) it will run the specified event as in a 'doevent' call.

---------------------------------------

*getmapguildusers(<mapname>, <guild id>)

Returns the amount of characters from the specified guild on the given map.

Example:

	mes("You have "+getmapguildusers("prontera", getcharid(CHAR_ID_GUILD))+" guild members in Prontera.");

---------------------------------------

*getguildmember(<guild id>{, <type>});

This command will find all members of a specified guild and returns their names
(or character id or account id depending on the value of "type") into an array
of temporary global variables.

Upon executing this,

$@guildmembername$[] is a global temporary string array which contains all the
                     names of these guild members.
                     (only set when type is 0 or not specified)

$@guildmembercid[]   is a global temporary number array which contains the
                     character id of these guild members.
                     (only set when type is 1)

$@guildmemberaid[]   is a global temporary number array which contains the
                     account id of these guild members.
                     (only set when type is 2)

$@guildmembercount   is the number of guild members that were found.

The guild members will be found regardless of whether they are online or offline.
Note that the names come in no particular order.

Be sure to use $@guildmembercount to go through this array, and not
getarraysize(), because it is not cleared between runs of getguildmember().

For usage examples, see getpartymember().

---------------------------------------

*getguildonline(<guild id>{, <type>});

Returns the amount of players online in the specified guild id.
Returns -1 if the guild was not found.

Valid <type> are:
	GUILD_ONLINE_ALL         Returns the total amount of players online in the guild.
	GUILD_ONLINE_VENDOR      Returns the total amount of vendors online in the guild.
	GUILD_ONLINE_NO_VENDOR   Returns the total amount of non-vendors online in the guild.

---------------------------------------
//=====================================
2.2 - End of Guild-Related Commands
//=====================================
---------------------------------------

*getskilllv(<skill id>)
*getskilllv("<skill name>")

This function returns the level of the specified skill that the invoking
character has. If they don't have the skill, 0 will be returned. The full
list of character skills is available in 'db/(pre-)re/skill_db.txt'.

There are two main uses for this function, it can check whether the
character has a skill or not, and it can tell you if the level is high
enough.

Example 1:

	if (getskilllv(TF_THROWSTONE)) {
		// TF_THROWSTONE is defined in skill_db.txt and its value is 152
		mes("You have got the skill Throw Stone");
		close();
	}
	mes("You don't have Throw Stone");
	close();

Example 2:

	if (getskilllv(AL_HEAL) == 10) {
		mes("Your heal lvl has been maxed");
		close();
	}
	if (getskilllv(AL_HEAL) >= 5) {
		mes("Your heal lvl is 5 or more");
		close();
	}
	mes("You heal skill is below lvl 5");
	close();

---------------------------------------

*getskilllist();

This command sets a bunch of arrays with a complete list of skills the
invoking character has. Here's what you get:

@skilllist_id[]   - skill ids.
@skilllist_lv[]   - skill levels.
@skilllist_flag[] - see 'skill' for the meaning of skill flags.
@skilllist_count  - number of skills in the above arrays.

While getskilllv() is probably more useful for most situations, this is the
easiest way to store all the skills and make the character something else
for a while. Advanced job for a day? :) This could also be useful to see
how many skills a character has.

---------------------------------------

*getpetinfo(<type>)

This command will return the currently active pet information of the invoking character.
These fields are associate in 'db/(pre-)re/pet_db.conf'. Valid types are:

	PETINFO_ID            - Pet Database ID, stored in `pet` table to distinguish from other pets.
	PETINFO_CLASS         - Pet class ID. (Id field)
	PETINFO_NAME          - Pet Name, return "null" if there's no active pet.
	PETINFO_INTIMACY      - Pet Intimacy level. 1000 is full loyalty.
	PETINFO_HUNGRY        - Pet hungry level. 100 is completely full.
	PETINFO_RENAME        - Pet rename flag. 0 means this pet has not been named yet.
	PETINFO_GID           - Pet Game ID
	PETINFO_EGGITEM       - Pet EggItem
	PETINFO_FOODITEM      - Pet FoodItem
	PETINFO_ACCESSORYITEM - Pet AccessoryItem
	PETINFO_ACCESSORYFLAG - return 1 if the pet currently equipping accessory, return 0 otherwise.
	PETINFO_EVO_EGGID     - Pet Evolve EggID
	PETINFO_AUTOFEED      - Pet AutoFeed flag.

If the invoking player doesn't own a pet, this command will
return "null" for type PETINFO_NAME, and return 0 for other types.

---------------------------------------

*petstat(<flag>)

    @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
    @ /!\ This command is deprecated @
    @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

Returns current pet status, all are integers except name.
Returns 0 or "" if the player doesn't have pets.

Flags usable:
PET_CLASS
PET_NAME
PET_LEVEL
PET_HUNGRY
PET_INTIMATE

Example:
	.@i = petstat(PET_CLASS);

This command is deprecated and it should not be used in new scripts, as it is
likely to be removed at a later time. Please use 'getpetinfo' instead.

---------------------------------------

*getmonsterinfo(<mob ID>, <type>)

This function will look up the monster with the specified ID number in the
mob database and return the info set by TYPE argument.
It will return -1 if there is no such monster (or the type value is
invalid), or "null" if you requested the monster's name.

Valid types are listed in doc/constants.md:
	MOB_NAME               0
	MOB_LV                 1
	MOB_MAXHP              2

	MOB_DMG_TAKEN_RATE    23

Check sample in doc/sample/getmonsterinfo.txt

---------------------------------------

*addmonsterdrop(<mob id or name>, <item id>, <rate>)

This command will temporarily add a drop to an existing monster. If the
monster already drops the specified item, its drop rate will be updated to the
given value.

Both the monster and the item must be valid.  Acceptable values for the drop
rate are in the range [1:10000].

Return value will be 1 in case of success (the item was added or its drop rate
was updated), and 0 otherwise (there were no free item drop slots).

Example:
	// Add Poring Doll (741) to the Poring's (1002) drops, with 1% (100) rate
	addmonsterdrop(PORING, Poring_Doll, 100);

---------------------------------------

*delmonsterdrop(<mob id or name>, <item id>)

This command will temporarily remove a drop from an existing monster.

Both the monster and the item must be valid.

Return value will be true in case of success (the item was removed), and
false otherwise (the monster didn't have the specified item in its drop
list).

Example:
	// Remove Jellopy (909) from the Poring's (1002) drops
	delmonsterdrop(PORING, Jellopy);

---------------------------------------

*getmobdrops(<mob id>)

This command will find all drops of the specified mob and return the item
IDs and drop percentages into arrays of temporary global variables.
getmobdrops() returns true if successful and false if the mob ID doesn't
exist.

Upon executing this,

$@MobDrop_item[] is a global temporary number array which contains the
                 item IDs of the monster's drops.

$@MobDrop_rate[] is a global temporary number array which contains the
                 drop percentages of each item. (1 = .01%)

$@MobDrop_count  is the number of item drops found.

Be sure to use $@MobDrop_count to go through the arrays, and not
'getarraysize', because the temporary global arrays are not cleared
between runs of 'getmobdrops'. If a mob with 7 item drops is looked up,
the arrays would have 7 elements. But if another mob is looked up and it
only has 5 item drops, the server will not clear the arrays for you,
overwriting the values instead. So in addition to returning the 5 item
drops, the 6th and 7th elements from the last call remain, and you will
get 5+2 item drops, of which the last 2 don't belong to the new mob.
$@MobDrop_count will always contain the correct number (5), unlike
getarraysize() which would return 7 in this case.

Example:

	// get a Mob ID from the user
	input(.@mob_id);

	if (getmobdrops(.@mob_id)) { // getmobdrops() returns true on success
		// immediately copy global temporary variables into scope
		// variables, since we don't know when getmobdrops() will get
		// called again for another mob, overwriting your global temporary
		// variables.
		.@count = $@MobDrop_count;
		copyarray(.@item[0], $@MobDrop_item[0], .@count);
		copyarray(.@rate[0], $@MobDrop_rate[0], .@count);

		mes(getmonsterinfo(.@mob_id, MOB_NAME) + " - " + .@count + " drops found:");
		for (.@i = 0; .@i < .@count; ++.@i) {
			mes(.@item[.@i] + " (" + getitemname(.@item[.@i]) + ") " + .@rate[.@i]/100 + ((.@rate[.@i]%100 < 10) ? ".0":".") + .@rate[.@i]%100 + "%");
		}
	} else {
		mes("Unknown monster ID.");
	}
	close();

---------------------------------------

*skillpointcount()

Returns the total amount of skill points a character possesses
(SkillPoint + skill points used in skills) This command can be used to
check the currently attached characters total amount of skill points.
This means the skill points used in skill are counted, and added to
SkillPoints (number of skill points not used).

Example:

//This will set the temp character variable @skill_points to the amount of
//skill points, and then tell the player the value.
	@skill_points = skillpointcount();
	mes("You have "+@skill_points+" skill points in total!");

//Self-explanatory... :P
	if (skillpointcount() > 20)
		mes("Wow, you have more then 20 Skill Points in total!");

This command does not count skills which are set as flag 3 (permamently
granted) (e.g. ALL_BUYING_STORE/ALL_INCCARRY).
---------------------------------------

*getscrate(<effect type>, <base rate>{, <GID>})

This function will return the chance of a status effect affecting the
invoking character, in percent, modified by the their current defense
against said status. The 'base rate' is the base chance of the status
effect being inflicted, in percent.

	if (rand(100) > getscrate(Eff_Blind, 50)) {
		// do something
	}

You can see the full list of available effect types you can possibly
inflict in 'doc/constants.md' under 'Status effects'.

---------------------------------------
//=====================================
3 - Checking-Related Commands
//=====================================
---------------------------------------

*playerattached()

Returns the ID of the player currently attached to the script. It will
return 0 if no one is attached, or if the attached player no longer exists
on the map server. It is wise to check for the attached player in script
functions that deal with timers as there's no guarantee the player will
still be logged on when the timer triggers. Note that the ID of a player
is actually their account ID.

---------------------------------------

*isloggedin(<account id>{, <char id>})

This function returns true if the specified account is logged in and
false if they aren't. You can also pass the char_id to check for both
account and char id.

---------------------------------------

*checkweight(<item id>, <amount>{, <item id>, <amount>, <item id>, <amount>, ...})
*checkweight("<item name>", <amount>{, "<item name>", <amount>, "<item name>", <amount>, ...})
*checkweight2(<id_array>, <amount_array>)

These functions will compute and return true if the total weight of the
specified number of specific items does not exceed the invoking
character's carrying capacity, and false otherwise. It is important to
see if a player can carry the items you expect to give them, failing to
do that may open your script up to abuse or create some very unfair
errors.

The second function will check an array of items and amounts, and also
returns true on success and false on failure.

The functions, in addition to checking to see if the player is capable of
holding a set amount of items, also ensure the player has room in their
inventory for the item(s) they will be receiving.

Like getitem(), this function will also accept an 'english name' from
the database as an argument.

Example 1:

	if (checkweight(Apple, 10)) {
		getitem(Apple, 10);
	} else {
		mes("Sorry, you cannot hold this amount of apples!");
	}

Example 2:

	setarray(.@item[0], 512, 513, 514);
	setarray(.@amount[0], 10, 5, 5);
	if (!checkweight(.@item, .@amount)) {
		mes("Sorry, you cannot hold this amount of fruit!");
	}

---------------------------------------

*basicskillcheck()

This function will return the state of the configuration option
'basic_skill_check' in 'conf/map/battle.conf'. Returns true if the
option is enabled and false if it isn't. If the 'basic_skill_check'
option is enabled, which it is by default, characters must have a
certain number of basic skill levels to sit, request a trade, use
emotions, etc.  Making your script behave differently depending on
whether the characters must actually have the skill to do all these
things might in some cases be required.

---------------------------------------

*checkoption(<option number>{, <account id>})
*checkoption1(<option number>{, <account id>})
*checkoption2(<option number>{, <account id>})
*setoption(<option number>{, <flag>{, <account id>}});

The setoption() series of functions check for a so-called option that is
set on the invoking character. 'Options' are used to store status
conditions and a lot of other non-permanent character data of the yes-no
kind. For most common cases, it is better to use checkcart(),
checkfalcon(), checkmount() and other similar functions, but there are
some options which you cannot get at this way. If <account id> is given,
this player will be used instead of the invoking character.

Option numbers valid for the first (option) version of this command are:

0x000000 Option_Nothing   - No options
0x000001 Option_Sight     - Sight in effect.
0x000002 Option_Hide      - Hide in effect.
0x000004 Option_Cloak     - Cloaking in effect.
0x000008                  - Cart number 1 present.
0x000010 Option_Falcon    - Falcon present.
0x000020 Option_Riding    - Peco Peco present.
0x000040 Option_Invisible - GM Perfect Hide in effect.
0x000080                  - Cart number 2 present.
0x000100                  - Cart number 3 present.
0x000200                  - Cart number 4 present.
0x000400                  - Cart number 5 present.
0x000800 Option_Orcish    - Orc head present.
0x001000 Option_Wedding   - The character is wearing a wedding sprite.
0x002000                  - Ruwach is in effect.
0x004000 Option_Chasewalk - Chasewalk in effect.
0x008000 Option_Flying    - Flying or Xmas suit.
0x010000                  - Sighttrasher.
0x100000 Option_Wug       - Warg present.
0x200000 Option_Wugrider  - The character is riding a warg.

Option numbers valid for the second version (opt1) of this command are:

1 - Petrified.
2 - Frozen.
3 - Stunned.
4 - Sleeping.
6 - Petrifying (the state where you can still walk)

Option numbers valid for the third version (opt2) of this command are:

0x01 - Poisoned.
0x02 - Cursed.
0x04 - Silenced.
0x08 - Signum Crucis (plays a howl-like sound effect, but otherwise no
       visible effects are displayed)
0x10 - Blinded.
0x80 - Deadly poisoned.

Option numbers (except for opt1) are bit-masks - you can add them up to
check for several states, but the functions will return true if at least
one of them is in effect.

setoption() will set options on the invoking character. There are no
second and third versions of this command, so you can only change the
values in the first list (cloak, cart, ruwach, etc). If flag is 1 (default
when omitted), the option will be added to what the character currently
has; if 0, the option is removed.

This is definitely not a complete list of available option flag numbers.
Ask a core developer (or read the source: src/map/status.h) for the full
list.

---------------------------------------

*setcart({<type>})
*checkcart()

If <type> is 0 this command will remove the cart from the character.
Otherwise it gives the invoking character a cart. The cart given will be
cart number <type> and will work regardless of whether the character is a
merchant class or not.
Note: the character needs to have the skill MC_PUSHCART to gain a cart.

The accompanying function will return true if the invoking character has a
cart (any kind of cart) and false if they don't.

	if (checkcart())
		mes("But you already have a cart!");

---------------------------------------

*setfalcon({<flag>})
*checkfalcon()

If <flag> is 0 this command will remove the falcon from the character.
Otherwise it gives the invoking character a falcon. The falcon will be
there regardless of whether the character is a hunter or not. It will
(probably) not have any useful effects for non-hunters though.
Note: the character needs to have the skill HT_FALCON to gain a falcon.

The accompanying function will return true if the invoking character has a
falcon and false if they don't.

	if (checkfalcon())
		mes("But you already have a falcon!");

---------------------------------------

*setmount({<flag>{, <type>}})
*checkmount()

If <flag> is MOUNT_NONE this command will remove the mount from the
character.

Otherwise it gives the invoking character the desired combat mount, where
allowed by their class and skills.

If no flag is specified, the mount is automatically chosen according to the
character's class and skills.

The following flag values are accepted:

    MOUNT_NONE:
        - Dismount
    MOUNT_PECO:
        - PecoPeco (Knight series class)
        - GrandPeco (Crusader series class)
        - Gryphon (Royal Guard)
    MOUNT_WUG:
        - Warg (Ranger)
    MOUNT_MADO:
        - Mado Gear (Mechanic)
    MOUNT_DRAGON:
    MOUNT_DRAGON_GREEN:
    MOUNT_DRAGON_BROWN:
    MOUNT_DRAGON_GRAY:
    MOUNT_DRAGON_BLUE:
    MOUNT_DRAGON_RED:
        - Dragon (Rune Knight)
          if MOUNT_DRAGON is specified, a the default (green) dragon will be used.

Unlike 'setfalcon' and 'setcart' this will not work at all if they aren't of a
class which can ride a mount.

For clients PACKETVER_MAIN_NUM >= 20191120 || PACKETVER_RE_NUM >= 20191106
you can pass a <type> flag which specifies the madogear wanted.
The Available types:
	MADO_ROBOT
	MADO_SUITE

The accompanying function will return MOUNT_NONE if the invoking
character is not on a mount, and a non-zero value (according to the
above constants) if they are.
Note: in case of dragons, the returned value will always be MOUNT_DRAGON,
regardless of color.

	if (checkmount())
		mes("Leave your mount outside! No riding mounts on the floor here!");

	if (checkmount() == MOUNT_DRAGON)
		mes("Wow, your dragon is cool! Can I pet it?");

---------------------------------------

*setcashmount()
*hascashmount()

The 'setcashmount' function toggles cash mount for the invoking character.
It will return true if successful, false otherwise.

Note: Character must not be mounting a non-cash mount (eg. dragon, peco,
	  wug, etc.)

The accompanying function will return true if the invoking character has a
cash mount and false if they don't.

---------------------------------------

*checkwug()

This function will return true if the invoking character has a warg and false if
they don't.

---------------------------------------

*checkvending({"<Player Name>"})
*checkchatting({"<Player Name>"})

Checks if the player is vending or in a chatroom.
Name is optional, and defaults to the attached player if omitted.

Return values for 'checkvending' are
  0 = not vending
  1 = normal vending
  2 = vending using @autotrade

checkchatting() returns true if they are in a chat room, false if they are not.

Examples:
	//This will check if Aaron is vending, and if so, put a message in
	//front of the attached player saying Aaron is vending.
	if (checkvending("Aaron"))
		mes("Aaron is currently vending!");

	//This will check if the attached player in a chat room or not.
	if (checkchatting())
		mes("You are currently in a chat room!");

---------------------------------------

*checkidle({"<Player Name>"})

Returns the time, in seconds, that the specified player has been idle.
Name is optional, and defaults to the attached player if omitted.

---------------------------------------

*agitcheck()
*agitcheck2()

These functions will let you check whether the server is currently in WoE
mode (or WoE SE mode if the second function is called) and will return true
if War of Emperium is on and false if it isn't.

---------------------------------------

*isnight()

This functions will return true or false depending on whether the server is in
night mode or day mode:

	if (!isnight())
		mes("I only prowl in the night.");

---------------------------------------
//=====================================
3.1 - Checking Item-Related Commands
//=====================================
---------------------------------------

*isequipped(<item id>{, <item id>{, <item id>{, <item id>}}})

This function will return true if the invoking character has all of the item
IDs given equipped (if card IDs are passed, then it checks if the cards
are inserted into slots in the equipment they are currently wearing).
Theoretically there is no limit to the number of items that may be tested
for at the same time.
If even one of the items given is not equipped, false will be returned.

	// (Poring, Santa Poring, Poporing, Marin)
	if (isequipped(Poring_Card, Poring__Card, Poporing_Card, Marin_Card))
		mes("Wow! You're wearing a full complement of possible poring cards!");
	// (Poring)
	if (isequipped(Poring_Card))
		mes("A poring card is useful, don't you think?");
	// (Earring)
	if (isequipped(Earring_))
		mes("You got a pair of nice Earring.");

The function was meant for item scripts to support the cards released by
Gravity in February 2005, but it will work just fine in normal NPC scripts.

---------------------------------------

*isequippedcnt(<item id>{, <item id>{, <item id>{, <item id>}}})

This function is similar to isequipped(), but instead of true or false, it will
return the number of equipped items/cards in the list given that were found on the
invoking character.

	if (isequippedcnt(Poring_Card, Poring__Card, Poporing_Card, Marin_Card) == 4)
		mes("Finally got all four poring cards?");
	if (isequippedcnt(Helm_Of_Sun_, Earring_) == 2)
		mes("You equipped both Helm of Sun and Earring.");

---------------------------------------

*checkequipedcard(<card id>)

This function will return true if the card specified by it's item ID number
is inserted into any equipment they have in their inventory, currently
equipped or not.

---------------------------------------

*getequipisidentify(<equipment slot>)

This function will return true if an item in the specified equipment slot is
identified and false if it isn't. Since you can't even equip unidentified
equipment, there's a question of whether it can actually end up there, and
it will normally return true all the time if there is an item in this
equipment slot, which makes this script command kinda pointless.
For a list of equipment slots see getequipid().

//=====================================
4 - Player-Related Commands
//=====================================
---------------------------------------

*attachrid(<account ID>)
*detachrid()

These commands allow the manipulation of the script's currently attached
player. While attachrid() allows attaching of a different player by using
its account id for the parameter rid, detachrid() makes the following
commands run as if the script was never invoked by a player.

In case, that the player cannot be attached, such as, when the player went
offline in the mean time, attachrid() returns false, otherwise true.

---------------------------------------

*rid2name(<account id>)

Converts rid to name. Note: The player/monster/NPC must be online/enabled.
Good for PCKillEvent where you can convert 'killedrid' to the name of the
player.

Note: rid2name() may not produce correct character names since RID means
      account id.
      It will return the current online character of the account only.

---------------------------------------

*message(<account ID>, "<message>")
*message("<character name>", "<message>")

That command will send a message to the chat window of the character
specified by account ID or name. The text will also appear above the head
of that character. It will not be seen by anyone else.

---------------------------------------

*dispbottom("<message>"{, <color>})

This command will send the given message into the invoking character's
chat window. The color format is in RGB (0xRRGGBB), and default to green
if <color> field is left out.

---------------------------------------

*showscript("<message>"{, <GID>{, <send_target>}})

Makes the attached player or GID, display a message similiar to a chat,
this will be seen by everyone near the invoking character but will not
be displayed in the chat window.
send_target: (optional)
	AREA: show the message to everyone within the view range (default)
	SELF: show the message to the given unit GID only

---------------------------------------

*warp("<map name>", <x>, <y>{, <flag>})

This command will take the invoking character to the specified map, and if
wanted, specified coordinates too, but these can be random.

	warp("place", 50, 55);

This would take them to X 50 Y 55 on the map called "place". If your X and
Y coordinates land on an unwalkable map square, it will send the warped
character to a random place. Same will happen if they are both zero:

	warp("place", 0, 0);

Notice that while warping people to coordinates 0,0 will normally get them
into a random place, it's not certain to always be so. Darned if I know
where this is actually coded, it might be that this happens because square
0,0 is unwalkable on all official maps. Beware if you're using custom maps.

There are also three special 'map names' you can use:

"Random" will warp the player randomly on the current map.
"Save" and "SavePoint" will warp the player back to their save point.

If flag parameter is set to 0, after player warped will be not stopped
currend running npc script. Running script after warp can be issue for
Gravity client if warp to other maps.

---------------------------------------

*areawarp("<from map name>", <x1>, <y1>, <x2>, <y2>, "<to map name>", <x3>, <y3>{, <x4>, <y4>})

This command is similar to 'warp', however, it will not refer to the
invoking character, but instead, all characters within a specified area,
defined by the x1/y1-x2/y2 square, will be warped. Nobody outside the area
will be affected, including the activating character, if they are outside
the area.

	areawarp("place", 10, 10, 120, 120, "place2", 150, 150);

Everyone that is in the area between X 10 Y 10 and X 120 Y 120, in a
square shape, on the map called "place", will be affected, and warped to
"place2" X 150 Y 150.

	areawarp("place", 10, 10, 120, 120, "place2", 0, 0);

By using 0,0; as the destination coordinates it will take all the
characters in the affected area to a random set of co-ordinates on the
"place2" map.

	areawarp("place", 10, 10, 120, 120, "place2", 150, 150, 200, 200);

By using the optional x4 and y4 parameters, the destination coordinates
will be a random place within the defined x3/y3-x4/y4 square.

Like warp(), areawarp() will also explicitly warp characters randomly into
the current map if you give the 'to map name' as "Random".

See also warp().

---------------------------------------

*warpparty("<to map name>", <x>, <y>, <party id>{{, <ignore mapflags>}, "<from map name>"{, <include leader>}})

Warps a party to specified map and coordinate given the party ID, which
you can get with getcharid(CHAR_ID_PARTY). You can also request another party id given
a member's name with getcharid(CHAR_ID_PARTY, <player_name>).

You can use the following <to map name> for special warping behavior:
Random:       All party members are randomly warped in their current map
              (as if they all used a fly wing).
SavePointAll: All party members are warped to their respective save point.
SavePoint:    All party members are warped to the save point of the
              currently attached player (will fail if there's no player
              attached).
Leader:       All party members are warped to the leader's position. The
              leader must be online and in the current map-server for
              this to work.

If <ignore mapflags> is not 0, warpparty() ignores nowarp/noreturn restrictions
of the warped character's current map. <ignore mapflags> defaults to 0.

If you specify a <from map name>, warpparty() will only affect those on that map.

You can exclude Party leader from warping, by keeping include_leader option as false.

Example:

	mes("[Party Warper]");
	mes("Here you go!");
	close2();
	.@id = getcharid(CHAR_ID_PARTY);
	warpparty("prontera", 150, 100, .@id, true);
	close();

---------------------------------------

*warpchar("<mapname>", <x>, <y>, <char_id>)

Warps another player to specified map and coordinate given the char id,
which you can get with getcharid(CHAR_ID_CHAR, <player_name>). Obviously this is
useless if you want to warp the same player that is executing this script,
unless it's some kind of "chosen" script.

Example:

	warpchar("prontera", 150, 100, 150001);

---------------------------------------

*warpguild("<to map name>", <x>, <y>, <guild id>{{, <ignore mapflags>}, "<from map name>"})

Warps a guild to specified map and coordinate given the guild id, which
you can get with getcharid(CHAR_ID_GUILD). You can also request another guild id given
the member's name with getcharid(CHAR_ID_GUILD, <player_name>).

You can use the following <to map name> for special warping behavior:
Random:       All guild members are randomly warped in their current map
              (as if they all used a fly wing)
SavePointAll: All guild members are warped to their respective save point.
SavePoint:    All guild members are warped to the save point of the
              currently attached player (will fail if there's no player
              attached).

If <ignore mapflags> is not 0, warpguild() ignores nowarp/noreturn restrictions
of the warped character's current map. <ignore mapflags> defaults to 0.

If you specify a <from map name>, warpguild() will only affect those on that map.

Example:

	warpguild("prontera", x, y, Guild_ID); // Warp all guild members to Prontera,
					       // but check nowarp/noreturn restriction of their current map.
	warpguild("prontera", x, y, Guild_ID, 1); // Warp all guild members to Prontera.
	warpguild("prontera", x, y, Guild_ID, "payon"); // Warp guild members from Payon to Prontera,
							// but check nowarp/noreturn restriction of Payon.
	warpguild("prontera", x, y, Guild_ID, 1, "payon"); // Warp guild members from Payon to Prontera.

---------------------------------------

*warppartner("<map name>", <x>, <y>)

This function will find the invoking character's marriage partner, if any,
and warp them to the map and coordinates given. Go kidnap that spouse. :)
It will return true upon success and false if the partner is not online,
the character is not married, or if there's no invoking character (no
RID).
0,0 will, as usual, normally translate to random coordinates.

---------------------------------------

*savepoint("<map name>", <x>, <y>)

This command saves where the invoking character will return to upon
'return to save point', if dead or in some other cases. The two versions
are equivalent. Map name, X coordinate and Y coordinate should be
perfectly obvious. This ignores any and all map flags, and can make a
character respawn where no teleportation is otherwise possible.

	savepoint("place", 350, 75);

---------------------------------------

*heal(<hp>, <sp>)

This command will heal a set amount of HP and/or SP on the invoking
character.

	heal(30000, 0) // This will heal 30,000 HP
	heal(0, 30000) // This will heal 30,000 SP
	heal(300, 300) // This will heal 300 HP and 300 SP

This command just alters the hit points and spell points of the invoking
character and produces no other output whatsoever.

---------------------------------------

*itemheal(<hp>, <sp>)

This command heals given relative amounts of HP and/or SP on the invoking
character. Unlike heal, this command is intended for use in item scripts.
It applies potion-related bonuses, such as alchemist ranking, cards,
status changes.
It also applies a sp/vit-related bonus that is calculated by:
	heal = heal*[(100+STATUS*2)/100]
So if a player has 99 vit and the script is 'itemheal 5, 0':
	heal(hp) = 5*[(100+99*2)/100]
	heal(hp) = 14.9
	heal(hp) = 14
	heal(sp) = 0

When used inside an NPC script, potion-related bonuses are omitted.

There is also a nice example on using this with the rand() function, to
give you a random amount of healing.

	// If the player has 50 vit and no bonuses this will heal
	// anything from 200 to 300 HP and 5 SP
	itemheal(rand(100, 150), 5);

---------------------------------------

*percentheal(<hp>, <sp>)

This command will heal the invoking character. It heals the character, but
not by a set value - it adds percent of their maximum HP/SP.

	percentheal(100, 0); // This will heal 100% HP
	percentheal(0, 100); // This will heal 100% SP
	percentheal(50, 50); // This will heal 50% HP and 50% SP

So the amount that this will heal will depend on the total amount of HP or
SP you have maximum. Like heal(), this will not call up any animations or
effects.

---------------------------------------

*recovery({<account id>})
*recovery("<map name>"{, <x1>, <y1>, <x2>, <y2>})

This command will revive and restore full HP and SP to all characters currently
connected to the server. If an account id is supplied, it will instead only
affect this character. If a map is supplied it will affect a whole map or area.

---------------------------------------

*jobchange(<job number>{, <upper flag>})

This command will change the job class of the invoking character.

	jobchange(Job_Swordman); // This would change your player into a Swordman
	jobchange(Job_Swordman_High); // This would change your player into a Swordman High

This command does work with numbers, but you can also use job names. The
full list of job names and the numbers they correspond to can be found in
'doc/constants.md'.

'upper flag' can alternatively be used to specify the type of job one
changes to. For example, jobchange(Job_Swordman, 1); will change the
character to a high swordsman. The upper values are:
-1 (or when omitted): preserves the current job type.
0: Normal/standard classes
1: High/Advanced classes
2: Baby classes

This command will also set a permanent character-based variable
'jobchange_level' which will contain the job level at the time right
before changing jobs, which can be checked for later in scripts.

---------------------------------------

*jobname(<job number>)

This command retrieves the name of the given job using the names defined
in messages.conf.

	mes("[Kid]");
	mes("I never thought I'd met a "+jobname(Class)+" here of all places.");
	close();

---------------------------------------

*eaclass({<job number>})

This commands returns the "eA job-number" corresponding to the given
class, and uses the invoking player's class if none is given. The eA
job-number is also a class number system, but it's one that comes with
constants which make it easy to convert among classes. The command will
return -1 if you pass it a job number which doesn't have an eA job-number
equivalent.

	.@eac = eaclass();
	if ((.@eac&EAJ_BASEMASK) == EAJ_SWORDMAN)
		mes("Your base job is Swordman.");
	if (.@eac&EAJL_UPPER)
		mes("You are a rebirth job.");
	if ((.@eac&EAJ_UPPERMASK) == EAJ_SWORDMAN)
		mes("You must be a Swordman, Baby Swordman or High Swordman.");

For more information on the eA Job System, see the docs/ea_job_system.txt
file.

---------------------------------------
*roclass(<job number> {, <gender>})

Does the opposite of eaclass(). That is, given an eA job-number, it returns
the corresponding RO class number. A gender is required because both Bard
and Dancers share the same eA job-number (EAJ_BARDDANCER), and uses the
invoking player's gender if none is given (if no player is attached,
male will be used by default). The command will return -1 if there is no
valid class to represent the specified job (for example, if you try to get
the baby version of a Taekwon class).

	.@eac = eaclass();
	//Check if class is already rebirth
	if (.@eac&EAJL_UPPER) {
		mes("You look strong.");
		close();
	}
	.@eac = roclass(.@eac|EAJL_UPPER);
	//Check if class has a rebirth version
	if (.@eac != -1) {
		mes("Bet you can't wait to become a "+jobname(.@eac)+"!");
		close();
	}

---------------------------------------

*changebase(<job ID number>)

This command will change the appearance of the invoking character to that
of a specified job class. Nothing but appearance will change.

Examples:

	/* This example is an item script in the item db */
	{
		Id: 2338
		AegisName: "Wedding_Dress"
		Name: "Wedding Dress"
		Type: 5
		Buy: 43000
		Weight: 500
		Job: 0xFFFFFFFE
		Loc: 16
		Script: <"
			bonus(bMdef, 15);
			changebase(Job_Wedding);
		">
	},

changebase(Job_Novice); // Changes player to Novice sprite.

changebase(Class); // Changes player back to default sprite.

---------------------------------------

*classchange(<view id>, <type> {, <char id>})

This command is very ancient, it's origins are clouded in mystery.
It will send a 'display id change' packet to player with given char ID
or to everyone in the immediate area of the NPC object if char ID is 0 or
not passed, which will make the NPC look like a different sprite, an NPC
sprite ID, or a monster ID. This effect is not stored anywhere and will
not persist.
Note that you can't send a Job sprite ID

type is not used and should always be 0.

---------------------------------------

*changesex()

This command will change the gender for the attached character's account.
If it was male, it will become female, if it was female, it will become
male. The change will be written to the character server, the player will
receive the message: "Need disconnection to perform change-sex request..."
and the player will be immediately kicked to the login screen. When they
log back in, they will be the opposite sex.

If there are any Dancer/Gypsy or Bard/Clown characters on the account,
they will also have their skills reset upon 'changesex'.

---------------------------------------

*changecharsex()

This command is exactly same as changesex(), with an exception that,
character sex will be changed instead of account sex.
Requires client 2014-10-22 or greater.

---------------------------------------

*getexp(<base xp>, <job xp>)

This command will give the invoking character a specified number of base
and job experience points. Should be used as a quest reward. Negative values
won't work.
Is subject to EXP bonuses and to the `quest_exp_rate` config option.

	getexp(10000, 5000);

You can also assign directly to the parameters defined in
'doc/constants.md':

	BaseExp += 10000;
	JobExp += 5000;

You can also reduce the amount of experience points:

	BaseExp -= 10000;

When setting the parameters directly no bonuses or config options are applied.

---------------------------------------

*setlook(<look type>, <look value>)
*changelook(<look type>, <look value>)

'setlook' will alter the look data for the invoking character. It is used
mainly for changing the palette used on hair and clothes: you specify
which look type you want to change, then the palette you want to use. Make
sure you specify a palette number that exists/is usable by the client you
use. 'changelook' works the same, but is only client side (it doesn't save
the look value).

	// This will change your hair(6), so that it uses palette 8, what ever
	// your palette 8 is, your hair will use that color.

	setlook(LOOK_HAIR_COLOR, 8);

	// This will change your clothes(7), so they are using palette 1,
	// whatever your palette 1 is, your clothes will then use that set of
	// colors.

	setlook(LOOK_CLOTHES_COLOR, 1);

Here are the possible look types:

  0 - LOOK_BASE           Base sprite
  1 - LOOK_HAIR           Hairstyle
  2 - LOOK_WEAPON         Weapon
  3 - LOOK_HEAD_BOTTOM    Head bottom
  4 - LOOK_HEAD_TOP       Head top
  5 - LOOK_HEAD_MID       Head mid
  6 - LOOK_HAIR_COLOR     Hair color
  7 - LOOK_CLOTHES_COLOR  Clothes color
  8 - LOOK_SHIELD         Shield
  9 - LOOK_SHOES          Shoes
 10 - LOOK_BODY           Body(N/A)
 11 - LOOK_FLOOR          FLOOR(N/A)
 12 - LOOK_ROBE           Robe
 13 - LOOK_BODY2          Body style

Whatever 'shoes' means is anyone's guess, ask Gravity - the client does
nothing with this value. It still wants it from the server though, so it
is kept, but normally doesn't do a thing.

Only the look data for hairstyle, hair color and clothes color are saved
to the char server's database and will persist. The rest freely change as
the character puts on and removes equipment, changes maps, logs in and out
and otherwise you should not expect to set them. In fact, messing with
them is generally hazardous, do it at your own risk, it is not tested
what will this actually do - it won't cause database corruption and
probably won't cause a server crash, but it's easy to crash the client
with just about anything unusual.

However, it might be an easy way to quickly check for empty view IDs for
sprites, which is essential for making custom headgear.

Since a lot of people have different palettes for hair and clothes, it's
impossible to tell you what all the color numbers are. If you want a
serious example, there is a Stylist script inside the default Hercules
installation that you can look at: 'npc/custom/stylist.txt'

---------------------------------------

*pushpc(<direction>, <cells>)

This command will push the currently attached player to given direction by
given amount of square cells. Direction is the same as used when declaring
NPCs, and can be specified by using one of the DIR_* constants
(doc/constants.md).

The knock-back is not restricted by items or map flags, only obstacles are
taken into account. If there is not enough space to perform the push (e.g.
due to a wall), the character is pushed only up to the obstacle.

	// pushes the character 5 cells in 3 o'clock direction from it's
	// current position.
	pushpc(DIR_EAST, 5);

---------------------------------------

*montransform(<monster id>, <duration>{, <sc_type>{, <val1>{, <val2>{, <val3>{, <val4>}}}}})
*montransform("<monster name>", <duration>{, <sc_type>{, <val1>{, <val2>{, <val3>{, <val4>}}}}})

This command can transform your character into monster and you can still
use all your skills like a normal character.
Can only be removed when your killed or if you die or if duration is over.

for sc_type, val1, val2, val3, val4, see sc_start(), sc_start2(), sc_start4() commands.

---------------------------------------
//=====================================
4.1 - Player Item-Related Commands
//=====================================
---------------------------------------

*getitem(<item id>, <amount>{, <account ID>})
*getitem("<item name>", <amount>{, <account ID>})

This command will give a specific amount of specified items to the target
character. If the character is not online, nothing will happen.
If <account ID> is not specified, items will be created in the invoking
character inventory instead.

In the first and most commonly used version of this command, items are
referred to by their database ID number found in 'db/(pre-)re/item_db.txt'.

	getitem(Apple, 10); // The person will receive 10 apples
	getitem(Old_Violet_Box, 1);  // The person will receive 1 Old Violet Box

Giving an item ID of -1 will give a specified number of random items from
the list of those that fall out of Old Blue Box. Unlike in all other
cases, these will be unidentified, if they turn out to be equipment. This
is exactly what's written in the Old Blue Box's item script.

Other negative IDs also correspond to other random item generating item
tables:

Giving an item ID of -2 will produce the effects of Old Violet Box.
Giving an item ID of -3 will produce the effects of Old Card Album.
Giving an item ID of -4 will produce the effects of Gift Box.
Giving an item ID of -5 will produce the effects of Worn Out Scroll,
which, in current Git, drops only Jellopies anyway.

This transaction is logged if the log script generated transactions option
is enabled.

You may also create an item by it's name in the 'english name' field in
the item database:

    getitem("Red_Potion", 10); // Not recommended, use Red_Potion instead of "Red_Potion"

Which will do what you'd expect. If it can't find that name in the
database, apples will be created anyway.

This is used in pretty much all NPC scripts that have to do with items and
quite a few item scripts. For more examples check just about any official
script.

---------------------------------------

*getitem2(<item id>, <amount>, <identify>, <refine>, <attribute>, <card1>, <card2>, <card3>, <card4>{, <account ID>})
*getitem2("<item name>", <amount>, <identify>, <refine>, <attribute>, <card1>, <card2>, <card3>, <card4>{, <account ID>})

This command will give an amount of specified items to the invoking
character. If an optional account ID is specified, and the target
character is currently online, items will be created in their inventory
instead. If they are not online, nothing will happen. It works essentially
the same as 'getitem' (it even works for negative ID numbers the same way)
but is a lot more flexible.

Those parameters that are different from getitem() are:

identify	- Whether you want the item to be identified (1) or not (0).
refine		- For how many pluses will it be refined. It will not let you
			  refine an item higher than the max refine.
attribute	- Whether the item is broken (1) or not (0).
card1,2,3,4	- If you want a card compound to it, place the card ID number
			  into the specific card slot.

Card1-card4 values are also used to store name information for named
items, as well as the elemental property of weapons and armor. You can
create a named item in this manner, however, if you just need a named
piece of standard equipment, it is much easier to the 'getnameditem'
function instead.

You will need to keep these values if you want to destroy and then
perfectly recreate a named item, for this see getinventorylist().

If you still want to try creating a named item with this command because
'getnameditem' won't do it for you cause it's too limited, you can do it
like this. Careful, minor magic ahead.

	// First, let's get an ID of a character who's name will be on the
	// item. Only an existing character's name may be there.
	// Let's assume our character is 'Adam' and find his ID.

	.@charid = getcharid(CHAR_ID_CHAR, "Adam");

	// Now we split the character ID number into two portions with a
	// binary shift operation. If you don't understand what this does,
	// just copy it.

	.@card3 = .@charid & 65535;
	.@card4 = .@charid >> 16;

	// If you're inscribing non-equipment, .@card1 must be 254.
	// Arrows are also not equipment. :)
	.@card1 = 254;

	// For named equipment, card2 means the Star Crumbs and elemental
	// crystals used to make this equipment. For everything else, it's 0.

	.@card2 = 0;

	// Now, let's give the character who invoked the script some
	// Adam's Apples:

	getitem2(Apple, 1, 1, 0, 0, .@card1, .@card2, .@card3, .@card4);

This wasn't tested with all possible items, so I can't give any promises,
experiment first before relying on it.

To create equipment, continue this example it like this:

	// We've already have card3 and card4 loaded with correct
	// values so we'll just set up card1 and card2 with data
	// for an Ice Stiletto.

	// If you're inscribing equipment, .@card1 must be 255.
	.@card1 = 255;

	// That's the number of star crumbs in a weapon.
	.@sc = 2;

	// That's the number of elemental property of the weapon.
	.@ele = 1;

	// And that's the wacky formula that makes them into
	// a single number.
	.@card2 = .@ele+((.@sc*5)<<8);

	// That will make us an Adam's +2 VVS Ice Stiletto:

	getitem2(Stiletto, 1, 1, 2, 0, .@card1, .@card2, .@card3, .@card4);

Experiment with the number of star crumbs - I'm not certain just how much
will work most and what it depends on. The valid element numbers are:

 1 - Ice, 2 - Earth 3 - Fire 4 - Wind.

You can, apparently, even create duplicates of the same pet egg with this
command, creating a pet which is the same, but simultaneously exists in
two eggs, and may hatch from either, although, I'm not sure what kind of a
mess will this really cause.

---------------------------------------
*getitembound(<item id>, <amount>, <bound type>{, <account ID>})
*getitembound("<item name>", <amount>, <bound type>{, <account ID>})

This command behaves identically to getitem(), but the items created will be
bound to the target character as specified by the bound type. All items created
in this manner cannot be dropped, sold, vended, auctioned, or mailed, and in
some cases cannot be traded or stored.

Valid item bound types are:
 1 - IBT_ACCOUNT     - Account Bound
 2 - IBT_GUILD       - Guild Bound
 3 - IBT_PARTY       - Party Bound
 4 - IBT_CHARACTER   - Character Bound

---------------------------------------

*getitembound2(<item id>, <amount>, <identify>, <refine>, <attribute>, <card1>, <card2>, <card3>, <card4>, <bound type>)
*getitembound2("<item name>", <amount>, <identify>, <refine>, <attribute>, <card1>, <card2>, <card3>, <card4>, <bound type>)

This command behaves identically to getitem2(), but the items created will be
bound to the target character as specified by the bound type. All items created
in this manner cannot be dropped, sold, vended, auctioned, or mailed, and in
some cases cannot be traded or stored.

For a list of bound types see getitembound().

---------------------------------------

*countbound({<bound type>})

This function will return the number of bounded items in the character's
inventory, and sets an array @bound_items[] containing all item IDs of the
counted items. If a bound type is specified, only those items will be counted.

For a list of bound types see 'getitembound'.

Example:
	mes("You currently have "+countbound()+" bound items.");
	next();
	mes("The list of bounded items include:");
	for (.@i = 0; .@i < getarraysize(@bound_items); ++.@i)
		mes(getitemname(@bound_items[.@i]));
	close();

---------------------------------------

*checkbound(<item_id>{, <bound_type>{, <refine>{, <attribute>{, <card_1>{, <card_2>{, <card_3>{, <card_4>}}}}}}})

This command allows you to check whether or not the attached player has the specified bound item in their inventory.
If a bound type is not specified or a bound type of 0 is used, it will search the player's inventory for a bound item
of any type, so long as the other parameters match. In all cases, this command will return the bound type of the
item found, or 0 if the specified item was not found.

Valid item bound types are:
 0 - IBT_ANY         - Any Bound
 1 - IBT_ACCOUNT     - Account Bound
 2 - IBT_GUILD       - Guild Bound
 3 - IBT_PARTY       - Party Bound
 4 - IBT_CHARACTER   - Character Bound

Optional Parameters:
 bound_type - checks to see if the item has the specified bound type.
 refine - checks to see if the item is refined to the given number.
 attribute - whether the item is broken (1) or not (0).
 card 1,2,3,4 - checks to see if the specified cards are compounded on the item as well.

Example:
	// This will check if you have a bound (any type) 1205 (Cutter).
	if (checkbound(Cutter)) {
		mes("You have a bound Cutter");
	} else {
		mes("You do not have a bound Cutter");
	}
	close();

	// This will also check if you have a bound (any type) 1205 (Cutter).
	if (checkbound(Cutter, IBT_ANY)) {
		mes("You have a bound Cutter");
	} else {
		mes("You do not have a bound Cutter");
	}
	close();

	// This will check if the player doesn't have a bound 1205 (Cutter).
	if (!checkbound(Cutter)) {
		mes("You do not have a bound Cutter");
	} else {
		mes("You do have a bound Cutter");
	}
	close();

	// This will check if the item found, has a bound type of IBT_GUILD
	if (checkbound(Cutter) == IBT_GUILD) {
		mes("You have a guild_bound Cutter");
	} else {
		mes("You do not have a guild_bound Cutter.");
	}
	close();

	// This will check if you have a 'guild_bound' +7 1205 (Cutter).
	if (checkbound(Cutter, IBT_GUILD, 7)) {
		mes("You have a +7 guild_bound Cutter.");
	} else {
		mes("You don't have the required item.");
	}
	close();
---------------------------------------

*getnameditem(<item id>, "<character name>")
*getnameditem(<item id>, <character ID>)
*getnameditem("<item name>", "<character name>")
*getnameditem("<item name>", <character ID>)

Create an item signed with the given character's name.

The command returns true when the item is created successfully, or false
if it fails. Failure occurs when:
- There is no player attached.
- Item name or ID is not valid.
- The given character ID/name is offline.

Example:

//This will give the currently attached player a Aaron's Apple (if Aaron
//is online).
	getnameditem(Apple, "Aaron");

//Self-explanatory (I hope).
	if (getnameditem(Apple, "Aaron")) {
		mes("You now have a Aaron's Apple!");
	}

---------------------------------------

*rentitem(<item id>, <time>)
*rentitem("<item name>", <time>)

Creates a rental item in the attached character's inventory. The item will
expire in <time> seconds and be automatically deleted. When receiving a
rental item, the character will receive a message in their chat window.
The character will also receive warning messages in their chat window
before the item disappears.

This command can not be used to rent stackable items. Rental items cannot
be dropped, traded, sold to NPCs, or placed in guild storage (i.e. trade
mask 75).
Note: delitem() in an NPC script can still remove rental items.

---------------------------------------

*makeitem(<item id>, <amount>, "<map name>", <X>, <Y>)
*makeitem("<item name>", <amount>, "<map name>", <X>, <Y>)

This command will create an item lying around on a specified map in the
specified location.

	itemid   - Found in 'db/(pre-)re/item_db.txt'
	amount   - Amount you want produced
	map name - The map name
	X        - The X coordinate
	Y        - The Y coordinate.

This item will still disappear just like any other dropped item. Like
getitem(), it also accepts an 'english name' field from the database and
creates apples if the name isn't found.
If the map name is given as "this", the map the invoking character is on
will be used.

---------------------------------------

*makeitem2(<item id>,<amount>,<identify>,<refine>,<attribute>,<card1>,<card2>,<card3>,<card4>,{"<map name>",<X>,<Y>,<range>})
*makeitem2("<item name>",<amount>,<identify>,<refine>,<attribute>,<card1>,<card2>,<card3>,<card4>,{"<map name>",<X>,<Y>,<range>})

This script command work like 'makeitem', but it has additional parameters
to expand the usage of the scritp command.

Parameter List:
	itemid		- ID / Name of an item
	amount		- Amount you want produced (Value: 1~MAX_AMOUNT)
				- if item type is Armor/Wepaon/PetEgg/PetArmor, amount will be limit to 1
	identify	- Item to be identified (1) or not (0)
	refine		- Refine count of item. (Value: 0 ~ MAX_REFINE)
	attribute	- Item is broken (1) or not (0)
	card1,2,3,4	- Card IDs that compound on each slot

Optional Parameter List:
	map name	- Map name (Default to attached player map)
	X,Y			- The coordinate of item will be dropped
					If value = 0, it's drop random across the map
					If value = -1, its drop around player
	range		- Range of item drop around player. (Value: 1 ~ battle_config.area_size, Default: 3)
					Default value will be used if no player are attached to the script.

---------------------------------------

*cleanarea("<map name>",<x1>,<y1>,<x2>,<y2>)
*cleanmap("<map name>")

These commands will clear all items lying on the ground on the specified
map, either within the x1/y1-x2/y2 rectangle or across the entire map.

---------------------------------------

*searchitem(<array name>, "<item name>")

This command will fill the given array with the ID of items whose name
matches the given one. It returns the number of items found. For
performance reasons, the results array is limited to 10 items.

	mes("What item are you looking for?");
	input(.@name$);
	.@qty = searchitem(.@matches[0], .@name$);
	mes("I found "+.@qty+" items:");
	for (.@i = 0; .@i < .@qty; ++.@i)
		//Display name (eg: "Apple[0]")
		mes(getitemname(.@matches[.@i])+"["+getitemslots(.@matches[.@i])+"]");

---------------------------------------

*delitem(<item id>, <amount>{, <account ID>})
*delitem("<item name>", <amount>{, <account ID>})

This command will remove a specified amount of items from the invoking or
target character. Like all the item commands, it uses the item ID found
inside 'db/(pre-)re/item_db.txt'.

	delitem(Apple, 10); // The person will lose 10 apples
	delitem(Old_Violet_Box, 1);  // The person will lose 1 Old Violet Box

It is always a good idea to check if the player actually has the items
before you delete them. If you try to delete more items that the player
has, the player will lose the ones he/she has and the script will be
terminated with an error.

Like getitem() this command will also accept an 'english name' field from
the database. If the name is not found, nothing will be deleted.

---------------------------------------

*delitem2(<item id>, <amount>, <identify>, <refine>, <attribute>, <card1>, <card2>, <card3>, <card4>{, <account ID>})
*delitem2("<item name>", <amount>, <identify>, <refine>, <attribute>, <card1>, <card2>, <card3>, <card4>{, <account ID>})

This command will remove a specified amount of items from the invoking or
target character.
Check getitem2() to understand its expanded parameters.

---------------------------------------

*delitemidx(<index>{, <amount>{, <account id>}})

This command will remove an item at the given inventory index. Unlike the
'delitem()' counterpart, this doesn't check invalid Item ID, making it useful to remove
invalid item IDs in player's inventory.

If <amount> is not specified, this will remove all of the items at the specified index.
Note that items with the 'ForceSerial' flag, not yet merged through 'mergeitem()', will only
be removed at the given index.

The only way to get the inventory index is by using 'getinventorylist()'. After deleting
an item at the given index, that index can remain empty until the player relogs, so you
should recall 'getinventorylist()' again. If you try to delete an item at an invalid index, the
script will terminate with an error.

This command is also useful to remove rental/bound items because 'delitem()'
does not discriminate at choosing which item to remove.

Example:

	// This will remove all invalid Item ID in player's inventory
	getinventorylist();
	for (.@i = 0; .@i < @inventorylist_count; ++.@i)
		if (getiteminfo(@inventorylist_id[.@i], ITEMINFO_TYPE) == -1)
			delitemidx(@inventorylist_idx[.@i]);

---------------------------------------

*countitem(<item id>)
*countitem("<item name>")

This function will return the number of items for the specified item ID
that the invoking character has in the inventory.

	mes("[Item Checker]");
	mes("Hmmm, it seems you have "+countitem(Apple)+" apples");
	close;

Like getitem(), this function will also accept an 'english name' from the
database as an argument.

---------------------------------------

*countitem2(<item id>, <identify>, <refine>, <attribute>, <card1>, <card2>, <card3>, <card4>)
*countitem2("<item name>", <identify>, <refine>, <attribute>, <card1>, <card2>, <card3>, <card4>)

Expanded version of countitem() function, used for created/carded/forged
items.

This function will return the number of items for the specified item ID
and other parameters that the invoking character has in the inventory.
Check getitem2() to understand the arguments of the function.

---------------------------------------

*countnameditem(<item id>, "<character name>")
*countnameditem(<item id>, <character ID>)
*countnameditem("<item name>", "<character name>")
*countnameditem("<item name>", <character ID>)

This function will return the number of signed items for the specified item ID
that the invoking character has in their inventory.

	mes("[Item Checker]");
	if (countnameditem(Apple) > 0) {
		mes("You have an apple with your name on it!");
	} else {
		mes("You do not have an apple with your name on it.");
	}
	next();
	mes("[Item Checker]");
	mesf("You have %d apples with John's name on it!", countnameditem(Apple, "John"));
	close();

Like getnameditem(), this function will also accept an 'english name' from the
database as an argument.

---------------------------------------

*groupranditem(<item id>)

Returns the item_id of a random item picked from the item container specified. There
are different item containers and they are specified in 'db/(pre-)re/item_group.conf'.

Example:
   getitem(groupranditem(Old_Blue_Box), 1);

---------------------------------------

*getrandgroupitem(<item id>, <quantity>)

Similar to the above example, this command allows players to obtain the specified
quantity of a random item from the container. The different containers
are specified in 'db/(pre-)re/item_group.conf'.

Example:
   getrandgroupitem(Old_Blue_Box, 1);

---------------------------------------

*packageitem({item_id})

This command has only 1 param which is optional. If the package item_id is not provided, it
will try to use the item id from the item it is being used from (if called from an item script).
It runs a item package and grants the items accordingly to the attached player.

Example:

/* This example is an item script from the item db */
	{
		Id: 12477
		AegisName: "Gift_Bundle"
		Name: "Gift Bundle"
		Type: 2
		Buy: 0
		Script: <" packageitem(); ">
	},

---------------------------------------

*enable_items({<flag>})
*enableitemuse({<flag>})
*disable_items({<flag>})
*disableitemuse({<flag>})

These commands enable/disable item actions while interacting with a NPC.
When disable_items() is invoked, item actions defined by <flag> are disabled
during scripts until enable_items() is called or the script has terminated.
To avoid possible exploits, when disable_items() is invoked, it will only
disable item actions while running that script in particular.
Note that if a different script also invokes disable_items(), it will override
the last call so you may want to call this command at the start of your
script without assuming the effect is still in effect.
If <flag> is omitted all item actions will be disabled.
The enable_items() command enables item actions defined by <flag> during
scripts until disable_items() is invoked or the script has terminated.
If <flag> is omitted it defaults to 'item_enabled_npc' battle flag.
For a list of supported flags have a look at the description of
'item_enabled_npc' battle flag in 'conf/map/battle/items.conf'.
Unless disable_items() or enable_items() is invoked the script will use
'item_enabled_npc' battle flag by default.

Example:

	// This will disable changing equipment during this script.
	disable_items(ITEMENABLEDNPC_EQUIP);

---------------------------------------

*itemskill(<skill id>, <skill level>{, <flag>})
*itemskill("<skill name>", <skill level>{, <flag>})

This command meant for item scripts to replicate single-use skills in
usable items. It will not work properly if there is a visible dialog
window or menu.
If the skill is self or auto-targeting, it will be used immediately.
Otherwise, a target cursor is shown.
By default, all skill requirements are ignored.
Optional argument <flag> is a bitmask to manipulate how the skill is cast.
Since <flag> is a bitmask, the flags can be summed up.
Possible flags are:
 - 0x00 - ISF_NONE		- Skill is cast as if it has been used from skill tree.
				  (Same like <flag> was omitted.)
 - 0x01 - ISF_CHECKCONDITIONS	- Skill requirements are checked and consumed.
				  (SP are never checked/consumed.)
 - 0x02 - ISF_INSTANTCAST	- Skill is cast instantaneously.
 - 0x04 - ISF_CASTONSELF	- Skill is forcefully cast on invoking character,
				  without showing the target selection cursor.

Important: Items which use itemskill() should be of type IT_USABLE.
           If the item type is IT_DELAYCONSUME and ISF_CHECKCONDITIONS isn't set,
           the item won't be consumed when using the item!

// When Anodyne is used, it will cast Endure, Level 1, as if the actual skill
// has been used from skill tree.
	itemskill(SM_ENDURE, 1);

// Instantaneously cast Level 10 Increase Agility on invoking character,
// with checking/consuming skill requirements (15 HP).
	itemskill(AL_INCAGI, 10, ISF_CHECKCONDITIONS | ISF_INSTANTCAST | ISF_CASTONSELF);
// Instaed of using the constants, one could also do it like this:
	itemskill(AL_INCAGI, 10, 7);

---------------------------------------

*itemeffect(<item id>)
*itemeffect("<item name>")
*consumeitem is an alias of itemeffect (added for compatibility)

This command will run the item script of the specified item on the
invoking character. The character does not need to posess the item, and
the item will not be deleted. While this command is intended for usable
items, it will run for any item type.

---------------------------------------

*produce(<item level>)

This command will open a crafting window on the client connected to the
invoking character. The 'item level' is a number which determines what
kind of a crafting window will pop-up.

You can see the full list of such item levels in 'db/produce_db.txt' which
determines what can actually be produced. The window will not be empty
only if the invoking character can actually produce the items of that type
and has the appropriate raw materials in their inventory.

The success rate to produce the item is the same as the success rate of
the skill associated with the item level. If there is no skill id, the
success rate will be 50%.

Valid item levels are:

 1   - Level 1 Weapons
 2   - Level 2 Weapons
 3   - Level 3 Weapons
 21  - Blacksmith's Stones and Metals
 22  - Alchemist's Potions, Holy Water, Assassin Cross's Deadly Poison
 23  - Elemental Converters

---------------------------------------

*cooking(<dish level>)

This command will open a produce window on the client connected to the
invoking character. The 'dish level' is the number which determines what
kind of dish level you can produce. You can see the full list of dishes
that can be produced in 'db/produce_db.txt'.

The window will be shown empty if the invoking character does not have
enough of the required incredients to cook a dish.

Valid dish levels are:

11 - Level 1 Dish
12 - Level 2 Dish
13 - Level 3 Dish
14 - Level 4 Dish
15 - Level 5 Dish
16 - Level 6 Dish
17 - Level 7 Dish
18 - Level 8 Dish
19 - Level 9 Dish
20 - Level 10 Dish

Although it's required to set a dish level, it doesn't matter if you set
it to 1 and you want to cook a level 10 dish, as long as you got the
required ingredients to cook the dish the command works.

---------------------------------------

*makerune(<% success bonus>)

This command will open a rune crafting window on the client connected to
the invoking character. Since this command is officially used in rune
ores, a bonus success rate must be specified (which adds to the base
formula).

You can see the full list of runes that can be produced in
'db/produce_db.txt'. The window will not be empty only if the invoking
character can actually produce a rune and has the appropriate raw
materials in their inventory.

---------------------------------------

*successremovecards(<equipment slot>)

This command will remove all cards from the item found in the specified
equipment slot of the invoking character, create new card items and give
them to the character. If any cards were removed in this manner, it will
also show a success effect.

---------------------------------------

*failedremovecards(<equipment slot>, <type>)

This command will remove all cards from the item found in the specified
equipment slot of the invoking character. 'type' determines what happens
to the item and the cards:

 0 - will destroy both the item and the cards.
 1 - will keep the item, but destroy the cards.
 2 - will keep the cards, but destroy the item.

Whatever the type is, it will also show a failure effect on screen.

---------------------------------------

*repair(<broken item number>)

This command repairs a broken piece of equipment, using the same list of
broken items as available through 'getbrokenid'.

The official scripts seem to use the repair command as a function instead:
'repair(<number>)' but it returns nothing on the stack. Probably only
Valaris, who made it, can answer why is it so.

---------------------------------------

*repairall()

This command repairs all broken equipment in the attached player's
inventory. A repair effect will be shown if any items are repaired, else
the command will end silently.

---------------------------------------

*successrefitem(<equipment slot>{, <upgrade_count>})

This command will refine an item in the specified equipment slot of the
invoking character by +1 (unless <upgrade_count> is specified).
For a list of equipment slots see 'getequipid'.
This command will also display a 'refine success'
effect on the character and put appropriate messages into their chat
window. It will also give the character fame points if a weapon reached
+10 this way, even though these will only take effect for blacksmith who
will later forge a weapon.

---------------------------------------

*failedrefitem(<equipment slot>)

This command will fail to refine an item in the specified equipment slot
of the invoking character. The item will be destroyed. This will also
display a 'refine failure' effect on the character and put appropriate
messages into their chat window.

---------------------------------------

*downrefitem(<equipment slot>{, <downgrade_count>})

This command will downgrade an item by - 1 (unless optional <downgrade_count> is provided)
in the specified equipment slot  of the invoking character.
So the item will not be destroyed unlike in the failedrefitem() script
command. This will also display a 'refine failure' effect on the
character and put appropriate messages into their chat window.

---------------------------------------

*unequip(<equipment slot>)

This command will unequip whatever is currently equipped in the invoking
character's specified equipment slot. For a full list of possible
equipment slots see 'getequipid'.

If an item occupies several equipment slots, it will get unequipped from
all of them.

---------------------------------------

*clearitem()

This command will destroy all items the invoking character has in their
inventory (including equipped items). It will not affect anything else,
like storage or cart.

---------------------------------------

*equip(<item id>)
*equip2(<item id>, <refine>, <attribute>, <card1>, <card2>, <card3>, <card4>)
*autoequip(<item id>, <option>)

These commands are to equip a equipment on the attached character.
The equip function will equip the item ID given when the player has this
item in his/her inventory, while the autoequip function will equip the
given item ID when this is looted. The option parameter of the autoequip
is 1 or 0, 1 to turn it on, and 0 to turn it off.

Examples:

//This will equip a 1104 (falchion) on the character if this is in the
//inventory.
	equip(Falchion);

//This will equip a +10 1104 (falchion) on the character if this is in the
//inventory.
	equip2(Falchion, 10, 0, 0, 0, 0, 0);

//The invoked character will now automatically equip a falchion when it's
//looted.
	autoequip(Falchion, 1);

//The invoked character will no longer automatically equip a falchion.
	autoequip(Falchion, 0);

---------------------------------------

*buyingstore(<slots>)

Invokes buying store preparation window like the skill 'Open Buying
Store', without the item requirement. Amount of slots is limited by the
server to a maximum of 5 slots by default.

Example:

	// Gives the player opportunity to buy 4 different kinds of items.
	buyingstore(4);

---------------------------------------

*searchstores(<uses>, <effect>);

Invokes the store search window, which allows to search for both vending
and buying stores. Parameter uses indicates, how many searches can be
started, before the window has to be reopened. Effect value affects what
happens when a result item is double-clicked and can be one of the
following:

	0 = Shows the store's position on the mini-map and highlights the shop
		sign with yellow color, when the store is on same map as the
		invoking player.
	1 = Directly opens the shop, regardless of distance.

Example:

	// Item Universal_Catalog_Gold (10 uses, effect: open shop)
	searchstores(10, 1);

---------------------------------------

*mergeitem();

mergeitem() opens the item merge window,
The Item merge window shows all stackable item(same ItemID) with different
serial, that can be merged into one stack.
Check sample: npc/other/item_merge.txt

---------------------------------------

*delequip(<equipment slot>)

This command will destroy whatever is currently equipped in the invoking
character's specified equipment slot. For a full list of possible equipment
slots see getequipid().

It is always a good idea to check if the player actually has the item you want
before you use this command. If you try to delete in a position that the player
has no gear, script will be terminated with an error.

---------------------------------------
//=====================================
4.1 - End of Player Item-Related Commands
//=====================================
---------------------------------------

*openstorage()

This will open character's Kafra storage window on the client connected to
the invoking character. It can be used from any kind of NPC or item
script, not just limited to Kafra Staff.

The storage window opens regardless of whether there are open NPC dialogs
or not, but it is preferred to close the dialog before displaying the
storage window, to avoid any disruption when both windows overlap.

	mes("I will now open your stash for you");
	close2();
	openstorage();
	end;

The mapflag 'nostorage' when set to type '2' (or 3), will not open the
account storage. Unless the character group has the permission 'bypass_nostorage'.
In case blocked by mapflag, returns 0.

---------------------------------------

*openmail()

This will open a character's Mail window on the client connected to the
invoking character.

	mes("Close this window to open your mail inbox.");
	close2();
	openmail();
	end;

---------------------------------------

*openauction()

This will open the Auction window on the client connected to the invoking
character.

	mes("Close this window to open the Auction window.");
	close2();
	openauction();
	end;

---------------------------------------

*dressroom({<mode>})

This command controls the dressing room for the attached player. If no <mode>
is passed, DRESSROOM_OPEN is used by default.

Valid <mode> for dressroom() are:
	DRESSROOM_OPEN     opens the dressing room window
	DRESSROOM_CLOSE    closes the dressing room window

Example:
	mes("Close this window to open the Dress Room window.");
	close2();
	dressroom(DRESSROOM_OPEN);
	end;

---------------------------------------
//=====================================
4.2 - Guild-Related Commands
//=====================================
---------------------------------------

*guildopenstorage()

This function works the same as openstorage() but will open a guild
storage window instead for the guild storage of the guild the invoking
character belongs to. This is a function because it returns a value - 0 if
the guild storage was opened successfully and 1 if it wasn't. (Notice,
it's a ZERO upon success.)
Since guild storage is only accessible to one character at one time, it
may fail if another character is accessing the guild storage at the same
time.

This will also fail and return 2 if the attached character does not belong
to any guild.

The mapflag 'nogstorage' when set to type '2' (or 3), will not open the
guild storage. Unless the character group has the permission 'bypass_nostorage'.
In case blocked by mapflag, returns 1.

---------------------------------------

*guildchangegm(<guild id>, <new master's name>)

This function will change the Guild Master of a guild. The ID is the
guild's id, and the new guild master's name must be passed.

Returns true on success, false otherwise.

---------------------------------------

*guildgetexp(<amount>)

This will give the specified amount of guild experience points to the
guild the invoking character belongs to. It will silently fail if they do
not belong to any guild.

---------------------------------------

*guildskill(<skill id>, <level>)
*guildskill("<skill name>", <level>)

This command will bump up the specified guild skill by the specified
number of levels. This refers to the invoking character and will only work
if the invoking character is a member of a guild AND it's guild master,
otherwise no failure message will be given and no error will occur, but
nothing will happen. The full list of guild skills is available in
'db/(pre-)re/skill_db.txt', these are all the GD_ skills at the end.
If a level higher than the maximum is given as parameter the skill will be
leveled to the maximum and not above.

// This would give your character's guild one level of Approval
// (GD_APPROVAL ID 10000). Notice that if you try to add two levels of
// Approval, or add Approval when the guild already has it, it will only
// have one level of Approval afterwards.
	guildskill(GD_APPROVAL, 1);

You might want to make a quest for getting a certain guild skill, make it
hard enough that all the guild needs to help or something. Doing this for
the Glory of the Guild skill, which allows your guild to use an emblem, is
a good idea for a fun quest. (Wasting a level point on that is really
annoying :D)

---------------------------------------
//=====================================
4.2 - End of Guild-Related Commands
//=====================================
---------------------------------------

*resetlvl(<action type>)

This is a character reset command, meant mostly for rebirth script
supporting Advanced jobs, which will reset the invoking character's stats
and level depending on the action type given. Valid action types are:

 1 - Base level 1, Job level 1, 0 skill points, 0 base exp, 0 job exp,
     wipes the status effects (only the ones settable by 'setoption'),
     sets all stats to 1. If the new job is 'Novice High', give 100 status
     points, give First Aid and Play Dead skills.
 2 - Base level 1, Job level 1, 0 skill points, 0 base exp, 0 job exp.
     Skills and attribute values are not altered.
 3 - Base level 1, base exp 0. Nothing else is changed.
 4 - Job level 1, job exp 0. Nothing else is changed.

In all cases everything the character has on will be unequipped.

---------------------------------------

*resetstatus()

This is a character reset command, which will reset the stats on the
invoking character and give back all the stat points used to raise them
previously. Nothing will happen to any other numbers about the character.

Used in reset NPC's (duh!).

---------------------------------------

*resetskill()

This command takes off all the skill points on the invoking character, so
they only have Basic Skill blanked out (lvl 0) left, and returns the
points for them to spend again. Nothing else will change but the skills.
Quest skills will also reset if 'quest_skill_reset' option is set to true in
'conf/map/battle.conf'. If the 'quest_skill_learn' option is set in there, the
points in the quest skills will also count towards the total.

Used in reset NPC's (duh!).

---------------------------------------

*resetfeel({<account id>})
*resethate({<account id>})

The first resets a character's 'Feeling' maps.
The second resets a character's 'Hatred' targets.

If no RID is given, will run with the current attached player.

---------------------------------------

*sc_start(<effect type>, <ticks>, <value 1>{, <rate>, <flag>{, <GID>}})
*sc_start2(<effect type>, <ticks>, <value 1>, <value 2>{, <rate>, <flag>{, <GID>}})
*sc_start4(<effect type>, <ticks>, <value 1>, <value 2>, <value 3>, <value 4>{, <rate>, <flag>{, <GID>}})
*sc_end(<effect type>{, <GID>})

These commands will bestow a status effect on a character.

The <effect type> determines which status is invoked. This can be either a number
or constant, with the common statuses (mostly negative) found in
'doc/constants.md' under 'Status Changes'. A full list is located in
'src/map/status.h', though they are not currently documented.

The duration of the status is given in <ticks>, or milleseconds.

Certain status changes take an additional parameter <value 1>, which typically
modifies player stats by the given number or percentage. This differs for each
status, and is sometimes zero.

Optional value <rate> is the chance that the status will be invoked (10000 = 1%).
This is used primarily in item scripts. When used in an NPC script, a flag MUST
be defined for the rate to work.

Optional value <flag> is how the status change start will be handled (a bitmask).
 SCFLAG_NONE      = 0x00: No special behavior.
 SCFLAG_NOAVOID   = 0x01: Status change cannot be avoided.
 SCFLAG_FIXEDTICK = 0x02: Tick cannot be reduced by stats (default).
 SCFLAG_LOADED    = 0x04: sc_data was loaded, no value will be altered.
 SCFLAG_FIXEDRATE = 0x08: Rate cannot be reduced.
 SCFLAG_NOICON    = 0x10: Status icon (SI) won't be shown.

If a <GID> is given, the status change will be invoked on the specified character
instead of the one attached to the script. This can only be defined after setting
a rate and flag.

sc_start2() and sc_start4() allow extra parameters to be passed, and are used only
for effects that require them. The meaning of the extra values vary depending on the
effect type.

sc_end() will remove a specified status effect. If SC_ALL (-1) is given, it will
perform a complete removal of all statuses (although permanent ones will re-apply).

Examples:
	// This will poison the invoking character for 10 minutes at 50% chance.
	sc_start(SC_POISON, 600000, 0, 5000);

	// This will bestow the effect of Level 10 Blessing.
	sc_start(SC_BLESSING, 240000, 10);

	// This will end the Freezing status for the invoking character.
	sc_end(SC_FREEZE);

Note: to use SC_NOCHAT you should alter Manner
	Manner = -5;	// Will mute a user for 5 minutes
	Manner = 0;	// Will unmute a user
	Manner = 5;	// Will unmute a user and prevent the next use of 'Manner'

---------------------------------------

*getstatus(<effect type>{, <type>})

Retrieve information about a specific status effect when called. Depending
on <type> specified the function will return different information.

Possible <type> values:
	- 0 or undefined: whether the status is active
	- 1: the val1 of the status
	- 2: the val2 of the status
	- 3: the val3 of the status
	- 4: the val4 of the status
	- 5: the amount of time in milliseconds that the status has remaining

If <type> is not defined or is set to 0, then the script function will
either return 1 if the status is active, or 0 if the status is not active.
If the status is not active when any of the <type> fields are provided,
this script function will always return 0.

---------------------------------------

*skilleffect(<skill id>, <number>)
*skilleffect("<skill name>", <number>)

This command displays visual and aural effects of given skill on currently
attached character. The number parameter is for skill whose visual effect
involves displaying of a number (healing or damaging). Note that this
command will not actually use the skill: it is intended for scripts which
simulate skill usage by the NPC, such as buffs, by setting appropriate
status and displaying the skill's effect.

	mes("Be blessed!");
	// Heal of 2000 HP
	heal(2000, 0);
	skilleffect(AL_HEAL, 2000);
	// Blessing Level 10
	sc_start(SC_BLESSING, 240000, 10);
	skilleffect(AL_BLESSING, 0);
	// Increase AGI Level 5
	sc_start(SC_INC_AGI, 140000, 5);
	skilleffect(AL_INCAGI, 0);

This will heal the character with 2000 HP, buff it with Blessing Lv 10 and
Increase AGI Lv 5, and display appropriate effects.

---------------------------------------

*npcskilleffect(<skill id>, <number>, <x>, <y>)
*npcskilleffect("<skill name>", <number>, <x>, <y>)

This command behaves identically to skilleffect(), however, the effect
will not be centered on the invoking character's sprite, nor on the NPC
sprite, if any, but will be centered at map coordinates given on the same
map as the invoking character.

---------------------------------------

*specialeffect(<effect number>{, <send_target>{, <unit id>{, <account id>}}})
*specialeffect(<effect number>{, <send_target>{, "<NPC Name>"{, <account id>}}})

This command will display special effect with the given number, centered
on the specified NPCs coordinates, if any. For a full list of special
effect numbers known see 'doc/effect_list.txt'. Some effect numbers are
known not to work in some client releases. (Notably, rain is absent from
any client executables released after April 2005.)

<NPC name> parameter will display <effect number> on another NPC. If the
NPC specified does not exist, the command will do nothing. When specifying
an NPC, <send_target> must be specified when specifying an <NPC Name>,
specifying AREA will retain the default behavior of the command.

<unit id> behaves like <NPC Name> except it can display the effect on
any kind of unit, not just NPC, by specifying its GID.

When <send_target> is SELF you can specify which player to send the effect
to by passing <account id>.

Example usage:

	// To make a NPC do an effect and show it to everyone:
	specialeffect(EF_HIT1, AREA, "John Doe#1");

	// To make a player do an effect and show it to everyone:
	specialeffect(EF_HIT1, AREA, getcharid(CHAR_ID_ACCOUNT, "player"));

	// To make a NPC do an effect and show it only to the attached player:
	specialeffect(EF_HIT1, SELF, "John Doe#1");

	// To make a NPC do an effect and show it only to another player:
	specialeffect(EF_HIT1, SELF, "John Doe#1", getcharid(CHAR_ID_ACCOUNT, "player"));

---------------------------------------

*specialeffectnum(<effect number>, <num1>, <num2>{, <send_target>{, <unit id>{, <account id>}}})
*specialeffectnum(<effect number>, <num1>, <num2>{, <send_target>{, "<NPC Name>"{, <account id>}}})

Works same as specialeffect but also send effect numbers to client.
For PACKETVER >= 20191127 support two numbers (num1, num2).
For older packet versions only num1 supported.

---------------------------------------

*removespecialeffect(<effect number>{, <send_target>{, <unit id>{, <account id>}}})
*removespecialeffect(<effect number>{, <send_target>{, "<NPC Name>"{, <account id>}}})

Works for:
	main client from version 2018-10-02
	re   client from version 2018-10-02
This command will remove special effect. All parameters same with specialeffect.
Examples and detailed explanation about parameters see in specialeffect.

---------------------------------------

*specialeffect2(<effect number>{, <send_target>{, "<Player Name>"}})

    @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
    @ /!\ This command is deprecated @
    @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

This command behaves identically to the specialeffect(), but the effect
will be centered on the invoking character's sprite.

This command is deprecated and it should not be used in new scripts, as it is
likely to be removed at a later time. Please use specialeffect instead,
ie: specialeffect(<effect number>, <send_target>, playerattached())

---------------------------------------

*statusup(<stat>)

This command will bump a specified stat of the invoking character up by
one permanently using status points to do so, if there aren't enough to perform
the change nothing will happen.
Stats are to be given as number, but you can use these constants to replace them:

bStr -  Strength
bVit -  Vitality
bInt -  Intelligence
bAgi -  Agility
bDex -  Dexterity
bLuk -  Luck

---------------------------------------

*statusup2(<stat>, <amount>)

This command will bump a specified stat of the invoking character up by
the specified amount permanently without using status points.
Amount can be negative. See statusup().

// This will decrease a character's Vit forever.
	statusup(bVit, -1);

---------------------------------------

*needed_status_point(<type>, <val>);

Returns the number of stat points needed to change the specified stat <type> by <val>.
If <val> is negative, returns the number of stat points that would be needed to
raise the specified stat from (current value - <val>) to current value.

List of <type>:
bStr -  Strength
bVit -  Vitality
bInt -  Intelligence
bAgi -  Agility
bDex -  Dexterity
bLuk -  Luck

*bonus(<bonus type>, <val1>)
*bonus2(<bonus type>, <val1>, <val2>)
*bonus3(<bonus type>, <val1>, <val2>, <val3>)
*bonus4(<bonus type>, <val1>, <val2>, <val3>, <val4>)
*bonus5(<bonus type>, <val1>, <val2>, <val3>, <val4>, <val5>)

These commands are meant to be used in item scripts. They will probably
work outside item scripts, but the bonus will not persist for long. They,
as expected, refer only to an invoking character.

You can find the full list of possible bonuses and which command to use
for each kind in 'doc/item_bonus.txt'.

---------------------------------------

*autobonus(<bonus script>, <rate>, <duration>{, <flag>, {<other script>}})
*autobonus2(<bonus script>, <rate>, <duration>{, <flag>, {<other script>}})
*autobonus3(<bonus script>, <rate>, <duration>, <skill id>, {<other script>})
*autobonus3(<bonus script>, <rate>, <duration>, "<skill name>", {<other script>})

These commands are meant to be used in item scripts. They will probably
work outside item scripts, but the bonus will not persist for long. They,
as expected, refer only to an invoking character.

What these commands do is 'attach' a script to the player which will get
executed on attack (or when attacked in the case of autobonus2()).

Rate is the trigger rate of the script (1000 = 100%).

Duration is the time that the bonus will last for since the script has
triggered.

Skill ID/skill name the skill which will be used as trigger to start the
bonus (for autobonus3()).

The optional argument 'flag' is used to classify the type of attack where
the script can trigger (it shares the same flags as the bAutoSpell bonus
script):

Range criteria:
	BF_SHORT:  Trigger on melee attack
	BF_LONG:   Trigger on ranged attack
	Default:   BF_SHORT+BF_LONG
Attack type criteria:
	BF_WEAPON: Trigger on weapon skills
	BF_MAGIC:  Trigger on magic skills
	BF_MISC:   Trigger on misc skills
	Default:   BF_WEAPON
Skill criteria:
	BF_NORMAL: Trigger on normal attacks
	BF_SKILL:  Trigger on skills
	default:   If the attack type is BF_WEAPON (only) BF_NORMAL is used,
		       otherwise BF_SKILL+BF_NORMAL is used.

The difference between the optional argument 'other script' and the 'bonus
script' is that, the former one triggers only when attacking (or attacked)
and the latter one runs on status calculation as well, which makes sure,
within the duration, the "bonus" that get lost on status calculation is
restored. So, 'bonus script' is technically supposed to accept "bonus"
command only. And we usually use 'other script' to show visual effects.

In all cases, when the script triggers, the attached player will be the
one who holds the bonus. There is currently no way of knowing within this
script who was the other character (the attacker in autobonus2(), or the
target in autobonus() and autobonus3()).

//Grants a 1% chance of starting the state "all stats +10" for 10 seconds
//when using weapon or misc attacks (both melee and ranged skills) and
//shows a special effect when the bonus is active.
	autobonus("{ bonus(bAllStats, 10); }", 10, 10000, BF_WEAPON|BF_MISC, "{ specialeffect(EF_FIRESPLASHHIT, AREA, playerattached()); }");

---------------------------------------

*skill(<skill id>, <level>{, <flag>})
*skill("<skill name>", <level>{, <flag>})
*addtoskill(<skill id>, <level>{, <flag>})
*addtoskill("<skill name>", <level>{, <flag>})

These commands will give the invoking character a specified skill. This is
also used for item scripts.

Level is obvious. Skill id is the ID number of the skill in question as
per 'db/(pre-)re/skill_db.txt'. It is not known for certain whether this
can be used to give a character a monster's skill, but you're welcome to
try with the numbers given in 'db/(pre-)re/mob_skill_db.txt'.

Flag is 0 if the skill is given permanently (will get written with the
character data) or 1 if it is temporary (will be lost eventually, this is
meant for card item scripts usage.).  The flag parameter is optional, and
defaults to 1 in 'skill' and to 2 in 'addtoskill'.

Flag 2 means that the level parameter is to be interpreted as a stackable
additional bonus to the skill level. If the character did not have that
skill previously, they will now at 0+the level given.

// This will permanently give the character Stone Throw
// (TF_THROWSTONE, 152), at level 1.
    skill(TF_THROWSTONE, 1, 0);

Flag 3 is the same as flag 0 in that it saves to the database. However,
these skills are ignored when any action is taken that adjusts the skill
tree (reset/job change).

---------------------------------------

*nude()

This command will unequip anything equipped on the invoking character.

It is not required to do this when changing jobs since jobchange() will
unequip everything not equippable by the new job class anyway.

---------------------------------------

*disguise(<Monster ID>)
*undisguise()

This command disguises the current player with a monster sprite.
The disguise lasts until undisguise() is issued or the player logs out.

Example:

disguise(PORING); // Disguise character as a Poring.
next();
undisguise(); // Return to normal character sprite.

---------------------------------------
//=====================================
4.3 - Marriage-Related Commands
//=====================================
---------------------------------------

*marriage("<spouse name>")

This function will marry two characters, the invoking character and the
one referred to by name given, together, setting them up as each other's
marriage partner. No second function call has to be issued (in current Git
at least) to make sure the marriage works both ways. The function returns
true upon success, or false if the marriage could not be completed, either
because the other character wasn't found or because one of the two
characters is already married.

This will do nothing else for the marriage except setting up the spouse ID
for both of these characters. No rings will be given and no effects will
be shown.

---------------------------------------

*wedding()

This command will call up wedding effects - the music and confetti -
centered on the invoking character. Example can be found in the wedding
script.

---------------------------------------

*divorce()

This function will "un-marry" the invoking character from whoever they
were married to. Both will no longer be each other's marriage partner,
(at least in current Git, which prevents the cases of multi-spouse
problems). It will return true upon success or false if the character
was not married at all.

This function will also destroy both wedding rings and send a message to
both players, telling them they are now divorced.

---------------------------------------
//=====================================
4.3 - End of Marriage-Related Commands
//=====================================
---------------------------------------

*pcfollow(<id>, <target id>)
*pcstopfollow(<id>)

Makes a character follow or stop following someone. This command does the
same as the @follow command. The main difference is that @follow can use
character names, and this commands needs the Account ID for the target.

Examples:

// This will make Aaron follow Bullah, when both of these characters are
// online.
	pcfollow(getcharid(CHAR_ID_ACCOUNT, "Aaron"), getcharid(CHAR_ID_ACCOUNT, "Bullah"));

// Makes Aaron stop following whoever he is following.
	pcstopfollow(getcharid(CHAR_ID_ACCOUNT, "Aaron"));

---------------------------------------

*pcblockmove(<account id>, <option>)

    @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
    @ /!\ This command is deprecated @
    @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

Prevents the player from moving when the option != 0, and 0 enables the
player to move again. The player has to be the account ID of a character,
and will run for the attached player if zero is supplied.

Examples:

// Prevents the current char from moving away.
	pcblockmove(getcharid(CHAR_ID_ACCOUNT), true);

// Enables the current char to move again.
	pcblockmove(getcharid(CHAR_ID_ACCOUNT), false);

---------------------------------------

*setpcblock(<type>, <option>{, <account id>})
*checkpcblock({<account id>})

Prevents a character from doing the following action.

For setpcblock, when the <option> is true(1) will block them, and false(0)
will allow those actions again.

The setpcblock command returns 1 on success or 0 if no character was attached.

The checkpcblock command returned value is a bit mask of the currently
enabled block flags (or PCBLOCK_NONE when none is set).

Parameter <account id> is optional for both commands.
If omitted, the currently attached character is used.

The <type> listed are a bit mask of the following:
	PCBLOCK_NONE (only used by checkpcblock)
	PCBLOCK_MOVE
	PCBLOCK_ATTACK
	PCBLOCK_SKILL
	PCBLOCK_USEITEM
	PCBLOCK_CHAT
	PCBLOCK_IMMUNE
	PCBLOCK_SITSTAND
	PCBLOCK_COMMANDS
	PCBLOCK_NPC

Examples:

// Make the current attached player invulnerable, same as @monsterignore
	setpcblock(PCBLOCK_IMMUNE, true);

// Prevents the current char from attacking or using skills
	setpcblock(PCBLOCK_ATTACK|PCBLOCK_SKILL, true);

// Re-enables attack, skills and item use
	setpcblock(PCBLOCK_ATTACK|PCBLOCK_SKILL|PCBLOCK_USEITEM, false);

// checkpcblock related checks
	if ((checkpcblock() & PCBLOCK_IMMUNE) != 0)
		mes "You are invulnerable!";

	if ((checkpcblock() & (PCBLOCK_MOVE|PCBLOCK_SITSTAND)) == (PCBLOCK_MOVE|PCBLOCK_SITSTAND))
		mes "You can't walk or sit";

	if ((checkpcblock() & (PCBLOCK_ATTACK|PCBLOCK_SKILL)) == PCBLOCK_NONE)
		mes "You can attack and use skills";

	if ((checkpcblock() & PCBLOCK_CHAT) == PCBLOCK_NONE)
		mes "You can't chat";

---------------------------------------

*monster("<map name>", <x>, <y>, "<name to show>", <mob id>, <amount>{, "<event label>"{, <size>{, <ai>}}})
*areamonster("<map name>", <x1>, <y1>, <x2>, <y2>, "<name to show>", <mob id>, <amount>{, "<event label>"{, <size>{, <ai>}}})

This command will spawn a monster on the specified coordinates on the
specified map. If the script is invoked by a character, a special map
name, "this", will be recognized to mean the name of the map the invoking
character is located at. This command works fine in the item scripts.

The same command arguments mean the same things as described above in the
beginning of this document when talking about permanent monster spawns.
Monsters spawned in this manner will not respawn upon being killed.

Unlike the permanent monster spawns, if the mob id is -1, a random monster
will be picked from the entire database according to the rules configured
in the server for dead branches. This will work for all other kinds of
non-permanent monster spawns.

The only very special thing about this command is an event label, which is
an optional parameter. This label is written like
'<NPC object name>::<label name>' and upon the monster being killed, it
will execute the script inside of the specified NPC object starting from
the label given. The RID of the player attached at this execution will be
the RID of the killing character.

<size> can be:
	Size_Medium = medium (default)
	Size_Small = small
	Size_Large = big

<ai> can be:
	0 = none (default)
	1 = attack/friendly
	2 = sphere (Alchemist skill)
	3 = flora (Alchemist skill)
	4 = zanzou (Kagerou/Oboro skill)

	monster("place", 60, 100, "Poring", PORING, 1, "NPCNAME::OnLabel");

The coordinates of 0,0 will spawn the monster on a random place on the
map. Both 'monster' and 'areamonster' return the GID of the monster
spawned if there was ONLY ONE monster to be spawned. This is useful for
controlling each of the spawned mobs with the unit* commands shown below.
For example:

	// We'll make a poring which will automatically attack invoking player:
	.@mobGID = monster("prontera", 150, 150, "Poring", PORING, 1); // PORING is defined in the mob db and its value is 1002
	unitattack(.@mobGID, getcharid(CHAR_ID_ACCOUNT)); // Attacker GID, attacked GID

The way you can get the GID of more than only one monster is looping
through all the summons to get their individual GIDs and do whatever you
want with them. For example:

	// We want to summon .mobnumber porings which will give us a kiss
	for (.@i = 0; .@i < .mobnumber; ++.@i) {
		.@mobGID = monster("map", .x, .y, "Kisser Poring", PORING, 1);
		unitemote(.@mobGID, e_kis);
	}

Refer to the unit* commands below.

The areamonster() command works much like the monster() command and is not
significantly different, but spawns the monsters within a square defined
by x1/y1-x2/y2.

Simple monster killing script:

	<NPC object definition. Let's assume you called him NPCNAME.>
		mes("[Summon Man]");
		mes("Want to start the kill?");
		next();
		if (select("Yes", "No") != 1) {
			mes("[Summon Man]");
			mes("Come back later");
			close();
		}
		monster("prontera", 0, 0, "Quest Poring", PORING, 10, "NPCNAME::OnPoringKilled");
		// By using 0,0 it will spawn them in a random place.
		mes("[Summon Man]");
		mes("Now go and kill all the Poring I summoned");
		// He summoned ten.
		close();
	OnPoringKilled:
		++$poring_killed;
		if ($poring_killed == 10) {
			announce("Summon Man: Well done all the poring are dead", bc_self);
			$poring_killed = 0;
		}
		end;

For more examples see just about any official 2-1 or 2-2 job quest script.

---------------------------------------

*areamobuseskill("<map name>", <x>, <y>, <range>, <mob id>, <skill id>, <skill level>, <cast time>, <cancelable>, <emotion>, <target type>)
*areamobuseskill("<map name>", <x>, <y>, <range>, <mob id>, "<skill name>", <skill level>, <cast time>, <cancelable>, <emotion>, <target type>)

This command will make all monsters of the specified mob ID in the
specified area use the specified skill. Map name, x, and y define the
center of the area, which extending <range> cells in each direction (ex: a
range of 3 would create a 7x7 square). The skill can be specified by skill
ID or name. <cast time> is in milliseconds (1000 = 1 second), and the rest
should be self-explanatory.

<target type> can be:
	0 = self
	1 = the mob's current target
	2 = the mob's master
	3 = random target

Example:

	// spawn 1 Shining Plant in the 5x5 area centered on (155,188)
	areamonster("prontera", 153, 186, 157, 190, "Shining Plant", SHINING_PLANT, 1);
	// make the plant cast level 10 Cold Bolt on a random target
	areamobuseskill("prontera", 155, 188, 2, SHINING_PLANT, MG_COLDBOLT, 10, 3000, 1, e_gg, 3)

---------------------------------------

*killmonster("<map name>", "<event label>"{, <type>})

This command will kill all monsters that were spawned with monster() or
areamonster() and have a specified event label attached to them. Commonly
used to get rid of remaining quest monsters once the quest is complete.

If the label is given as "all", all monsters which have their respawn
times set to -1 (like all the monsters summoned with 'monster' or
'areamonster' script command, and all monsters summoned with GM commands,
but no other ones - that is, all non-permanent monsters) on the specified
map will be killed regardless of the event label value.

killmonster() supports an optional argument type. Using 1 for type will make
the command fire "OnMyMobDead" events from any monsters that do die as a
result of this command.

---------------------------------------

*killmonsterall("<map name>"{, <type>})

This command will kill all monsters on a specified map name, regardless of
how they were spawned or what they are without triggering any event label
attached to them, unless you specify 1 for type parameter. In this case,
mob death labels will be allowed totrigger when there is no player. Any
other number for this parameter won't be recognized.

---------------------------------------

*killmonstergid(<GID>);

This command will kill the specific monster GID. The difference between
this command and 'unitkill', is this command does not trigger monster's
event label.

---------------------------------------

*strmobinfo(<type>, <monster id>)

This function will return information about a monster record in the
database, as per 'db/(pre-)re/mob_db.txt'. Type is the kind of information
returned. Valid types are:

 1 - 'english name' field in the database, a string.
 2 - 'japanese name' field in the database, a string.
     All other returned values are numbers:
 3 - Level.
 4 - Maximum HP.
 5 - Maximum SP.
 6 - Experience reward.
 7 - Job experience reward.

---------------------------------------

*mobcount("<map name>", "<event label>")

This function will count all the monsters on the specified map that have a
given event label and return the number or 0 if it can't find any.
Naturally, only monsters spawned with 'monster' and 'areamonster' script
commands can have non-empty event label.
If you pass this function an empty string for the event label, it will
return the total count of monster without event label, including
permanently spawning monsters.

With the dynamic mobs system enabled, where mobs are not kept in memory
for maps with no actual people playing on them, this will return a 0 for
any such map.

If the event label is given as "all", all monsters will be counted,
regardless of having any event label attached.

If the map name is given as "this", the map the invoking character is on
will be used. If the map is not found, or the invoker is not a character
while the map is "this", it will return -1.

---------------------------------------

*clone("<map name>", <x>, <y>, "<event>", <char id>{, <master_id>{, <mode>{, <flag>, <duration>}}})

This command creates a monster which is a copy of another player. The
first four arguments serve the same purpose as in the monster script
command, The <char id> is the character id of the player to clone (player
must be online).
If <master id> is given, the clone will be a 'slave/minion' of it.
Master_id must be a character id of another online player.

The mode can be specified to determine the behavior of the clone, its
values are the same as the ones used for the mode field in the mob_db. The
default mode is aggressive, assists, can move, can attack.

Flag can be either zero or one currently. If zero, the clone is a normal
monster that'll target players, if one, it is considered a summoned
monster, and as such, it'll target other monsters. Defaults to zero.

The duration specifies how long the clone will live before it is
auto-removed. Specified in seconds, defaults to no limit (zero).

Returned value is the monster ID of the spawned clone. If command fails,
returned value is zero.

---------------------------------------

*summon("Monster name", <monster id>{, <Time Out>{, "event label"}})

This command will summon a monster. (see also monster()) Unlike monsters
spawned with other commands, this one will set up the monster to fight to
protect the invoking character. Monster name and mob id obey the same
rules as the one given at the beginning of this document for permanent
monster spawns with the exceptions mentioned when describing 'monster'
command.

The effect for the skill 'Call Homunculus' will be displayed centered on
the invoking character.

Timeout is the time in milliseconds the summon lives, and is set default
to 60000 (1 minute). Note that also the value 0 will set the timer to
default, and it is not possible to create a spawn that lasts forever.
If an event label is given, upon the monster being killed, the event label
will run as if by donpcevent().

// Will summon a poring to fight for the character.
	summon("--ja--", PORING);

---------------------------------------

*mobattached()

This command will return RID of the monster running from 'OnTouchNPC:' label.


//	Kill any monster entering npc's trigger area
OnTouchNPC:
	killmonstergid mobattached();

---------------------------------------

*homevolution()

This command will try to evolve the current player's homunculus.
If it doesn't work, the /swt emotion is shown.

To evolve a homunculus, the invoking player must have a homunculus, the
homunculus must not be the last evolution and the homunculus must have
above 91000 intimacy with its owner.

---------------------------------------

*gethominfo(<type>)

This function works as a direct counterpart of 'getpetinfo':
 0 - Homunculus unique ID
 1 - Homunculus Class
 2 - Name
 3 - Friendly level (intimacy score). 100000 is full loyalty.
 4 - Hungry level. 100 is completely full.
 5 - Rename flag. 0 means this homunculus has not been named yet.
 6 - Homunculus level

If the attached player doesn't own a homunculus, this command will return
"null" for type 2, and return 0 for other types.

---------------------------------------

*morphembryo()

This command will try to put the invoking player's Homunculus in an
uncallable state, required for mutation into a Homunculus S. The player
will also receive a Strange Embryo (ID 6415) in their inventory if
successful, which is deleted upon mutation.

The command will fail if the invoking player does not have an evolved
Homunculus at level 99 or above. The /swt emotion is shown upon failure.

Returns 1 upon success and 0 for all failures.

---------------------------------------

*hommutate({<ID>})

This command will try to mutate the invoking player's Homunculus into a
Homunculus S. The Strange Embryo (Strange_Embryo, ID 6415) is deleted
upon success.

The command will fail if the invoking player does not have an evolved
Homunculus at level 99 or above, if it is not in the embryo state
(from the morphembryo() command), or if the invoking player does not
possess a Strange Embryo. The /swt emotion is shown upon failure.

If the optional parameter <ID> is set, the invoking player's Homunculus
will change into the specified Homunculus ID. Otherwise, a random Homunculus S
will be chosen. See 'db/homunculus_db.txt' for a full list of IDs.

Returns true upon success and false for all failures.

---------------------------------------

*checkhomcall()

This function checks if the attached player's Homunculus is active,
and will return the following values:
 -1: The player has no Homunculus.
  0: The player's Homunculus is active.
  1: The player's Homunculus is vaporized.
  2: The player's Homunculus is in morph state.

---------------------------------------

*getunittype(<GID>)

Returns the type of object from the given Game ID. Returns -1 if the given GID
does not exist. The return values are :-

	UNITTYPE_PC     0
	UNITTYPE_NPC    1
	UNITTYPE_PET    2
	UNITTYPE_MOB    3
	UNITTYPE_HOM    4
	UNITTYPE_MER    5
	UNITTYPE_ELEM   6

---------------------------------------

*unitwalk(<GID>, <x>, <y>)
*unitwalk(<GID>, <target_GID>)

This is one command, but can be used in two ways. If only the first
argument is given, the unit whose GID is given will start walking towards
the target whose GID is given.

When 2 arguments are passed, the given unit will walk to the given x,y
coordinates on the map where the unit currently is.

Examples:

//Will move/walk the poring we made to the coordinates 150,150
	unitwalk(.GID, 150, 150);

//NPC will move towards the attached player.
	unitwalk(.GID, getcharid(CHAR_ID_ACCOUNT));//a player's GID is their account ID

---------------------------------------

*unitiswalking({<GID>})

This command checks, if a unit is walking or not.
If <GID> is omitted, the currently attached character is used.
Returns 1 if the unit is walking, 0 if the unit is not walking and -1 on error.

Note: There's no differentiation between script and client initiated walking.

Example:

prontera,155,185,5	script	Check Walking	1_F_MARIA,{
	mes("Enter character name.");
	mes("");
	input(.@name$);
	.@GID = getcharid(CHAR_ID_ACCOUNT, .@name$);
	if (.@GID != 0) {
		.@iswalking = unitiswalking(.@GID);
		if (.@iswalking == 1)
			mesf("%s is walking.", .@name$);
		else if (.@iswalking == 0)
			mesf("%s is not walking.", .@name$);
		else
			mesf("Can't get %s's walking state.", .@name$);
	} else {
		mesf("%s not found!", .@name$);
	}
	close();
}

---------------------------------------

*unitkill(<GID>)
*unitwarp(<GID>, <Mapname>, <x>, <y>)
*unitattack(<GID>, <Target ID>)
*unitstop(<GID>)
*unittalk(<GID>, <Text>{, show_name{, <send_target>{, <target_id>}}})
*unitemote(<GID>, <Emote>)

Okay, these commands should be fairly self explaining.
For the emotions, you can look in 'doc/constants.md' under 'Emotes'
PS: unitwarp() supports a <GID> of zero, which causes the executor of the
PS: unittalk() can receive 3 extra parameters:
	show_name:
		true: Shows Unit name like "UnitName : Message" (default)
		false: Hides Unit name
	send_target:
		AREA_CHAT_WOC: sends the message to everyone in view range including the attached unit (default)
		SELF: sends the message to the given unit gid only
	target_id:
		if send_target is set to SELF, the message will be shown by the given gid,
		target_id allows changing the unit that will see the message.
script to be affected. This can be used with OnTouchNPC to warp
monsters:

OnTouchNPC:
	unitwarp(0, "this", -1, -1);

	// hide the npc name from the text
	unittalk(getnpcid(0), "foobar", false);

	// display by npc to everyone
	unittalk(getnpcid(0), "foobar", true);

	// display by npc to npc
	unittalk(getnpcid(0), "foobar", true, SELF);

	// display the text by the npc to the attached player only
	unittalk(getnpcid(0), "foobar", true, SELF, playerattached());

	// display by player to everyone
	unittalk(playerattached(), "foobar", true);

	// display by player to himself only
	unittalk(playerattached(), "foobar", true, SELF);

	// display the text by the 1st player to the attached player only
	unittalk(getcharid(CHAR_ID_ACCOUNT, "Name"), "foobar", true, SELF, playerattached());

---------------------------------------

*disablenpc("<NPC object name>")
*enablenpc("<NPC object name>")

These two commands will disable and enable, respectively, an NPC object
specified by name. The disabled NPC will disappear from sight and will no
longer be triggerable in the normal way. It is not clear whether it will
still be accessible through donpcevent() and other triggering commands,
but it probably will be. You can disable even warp NPCs if you know their
object names, which is an easy way to make a map only accessible through
walking half the time. Then you 'enablenpc' them back.

You can also use these commands to create the illusion of an NPC switching
between several locations, which is often better than actually moving the
NPC - create one NPC object with a visible and a hidden part to their
name, make a few copies, and then disable all except one.

---------------------------------------

*hideonnpc("<NPC object name>")
*hideoffnpc("<NPC object name>")

These commands will make the NPC object specified display as hidden or
visible, even though not actually disabled per se. Hidden as in thief Hide
skill, but unfortunately, not detectable by Ruwach or Sight.

As they are now, these commands are pointless, it is suggested to use
'disablenpc'/'enablenpc', because these two commands actually unload the
NPC sprite location and other accompanying data from memory when it is not
used. However, you can use these for some quest ideas (such as cloaking
NPCs talking while hidden then revealing... you can wonder around =P).

---------------------------------------

*cloakonnpc("<NPC object name>"{, <account_id>})
*cloakoffnpc("<NPC object name>"{, <account_id>})

These commands are used to apply the cloaking effect on npcs
this is a visual effect only and it does NOT stop the player
from interacting with the npc.

If an account_id is specified then the effect will only display to the given id,
otherwise it's displayed to the entire npc area.

---------------------------------------

*doevent("<NPC object name>::<event label>")

This command will start a new execution thread in a specified NPC object
at the specified label. The execution of the script running this command
will not stop, and the event called by the doevent() command will not run
until the invoking script has terminated. No parameters may be passed with
a doevent() call.

The script of the NPC object invoked in this manner will run as if it's
been invoked by the RID that was active in the script that issued a
'doevent'. As such, the command will not work if an RID is not attached.

	place,100,100,1%TAB%script%TAB%NPC%TAB%53,{
		mes("This is what you will see when you click me");
		close();
	OnLabel:
		mes("This is what you will see if the doevent is activated");
		close();
	}

	// ...

	doevent("NPC::OnLabel");

---------------------------------------

*donpcevent("<NPC object name>::<event label>")

This command invokes the event label code within an another NPC or NPCs.
It starts a separate instance of execution, and the invoking NPC will
resume execution its immediately.

If the supplied event label has the form "NpcName::OnLabel", then only
given NPC's event label will be invoked (much like goto() into another
NPC). If the form is "::OnLabel" (NPC name omitted), the event code of all
NPCs with given label will be invoked, one after another. In both cases
the invoked script will run without an attached RID, whether or not the
invoking script was attached to a player. The event label name is required
to start with "On".

This command can be used to make other NPCs act, as if they were
responding to the invoking NPC's actions, such as using an emotion or
talking.

	place,100,100,1%TAB%script%TAB%NPC%TAB%53,{
		mes("Hey NPC2 copy what I do");
		close2();
		@emote = rand(1, 30);
		donpcevent("NPC2::OnEmote");
	OnEmote:
		emotion(@emote);
		end;
	}

	place,102,100,1%TAB%script%TAB%NPC2%TAB%53,{
		mes("Hey NPC copy what I do");
		close2();
		@emote = rand(1, 30);
		donpcevent("NPC::OnEmote");
	OnEmote:
		emotion(@emote);
		end;
	}

Whichever of the both NPCs is talked to, both will show a random emotion
at the same time.

Command returns true or false on success and failure.
A debug message also shows on the console when no events are triggered.

---------------------------------------

*npctalk("<message>"{, "<npc name>"{, <show_name>}})

show_npcname values:
	true: shows npc name (default)
	false: hide npc name

This command will display a message to the surrounding area as if the NPC
object running it was a player talking - that is, above their head and in
the chat window. If show_npcname is true the name of the NPC will get appended in front of
the message, otherwise the npc name will not be shown.

	// This will make everyone in the area see the NPC greet the character
	// who just invoked it.
	npctalk("Hello "+strcharinfo(PC_NAME)+", how are you?");
	npctalk("Hello "+strcharinfo(PC_NAME)+", how are you?", "Another_NPC_Name");

---------------------------------------

*setnpcdisplay("<npc name>", "<display name>", <class id>, <size>)
*setnpcdisplay("<npc name>", "<display name>", <class id>)
*setnpcdisplay("<npc name>", "<display name>")
*setnpcdisplay("<npc name>", <class id>)

Changes the display name and/or display class of the target NPC.
Returns 0 is successful, 1 if the NPC does not exist.
Size is 0 = normal 1 = small 2 = big.

---------------------------------------
//=====================================
5.1 - Time-Related Commands
//=====================================
---------------------------------------

*addtimer(<ticks>, "NPC::OnLabel"{, <account id>})

This command will create a countdown timer.
The event label given is the identifier of that timer.
The timer runs on the character object that is attached to the script,
and can have multiple instances. If <acccount id> is passed, this player
will be used instead. When the label is run, it is run as if the player
that the timer runs on has clicked the NPC.

When this timer runs out, a new execution thread will start in the
specified NPC object at the specified label.

The ticks are given in 1/1000ths of a second.

One more thing. These timers are stored as part of player data. If the
player logs out, all of these get immediately deleted, without executing
the script. If this behavior is undesirable, use some other timer
mechanism (like sleep()).

Example:
<NPC Header> {
	dispbottom("Starting a 5 second timer...");
	addtimer(5000, strnpcinfo(NPC_NAME_UNIQUE)+"::On5secs");
	end;
On5secs:
	dispbottom("5 seconds have passed!");
	end;
}

---------------------------------------

*deltimer("NPC::OnLabel"{, <account id>})

Deletes timers created by addtimer() that matches the given event
label. Refer to addtimer() for additional information.

---------------------------------------

*addtimercount("NPC::OnLabel", <ticks>{, <account id>})

Delays a timer that was created with addtimer() by <ticks> ticks
if it matches the given event label. Refer to addtimer() for additional
information.

---------------------------------------

*gettimer(<type>{, <account id>{, "<event>"}})

Returns informations on timers that were created by addtimer().

valid <type> for gettimer() are:

(0) TIMER_COUNT
	Will return the total number of timers for the specified or
	attached player. Can be filtered by <event>.
(1) TIMER_TICK_NEXT
	Will return the number of ticks until the next timer runs
	for the specified or attached player. Can be filtered by <event>.
(2) TIMER_TICK_LAST
	Will return the number of ticks until the last timer runs
	for the specified or attached player. Can be filtered by <event>.

---------------------------------------

*initnpctimer({"<NPC name>"{, <Attach Flag>}})
*initnpctimer({<Attach Flag>})
*stopnpctimer({"<NPC name>"{, <Detach Flag>}})
*stopnpctimer({<Detach Flag>}})
*startnpctimer({"<NPC name>"{, <Attach Flag>}})
*startnpctimer({<Attach Flag>})
*setnpctimer(<tick>{, "<NPC name>"})
*getnpctimer(<type of information>{, "<NPC name>"})
*attachnpctimer({"<character name>"})
*detachnpctimer({"<NPC name>"})

This set of commands and functions will create and manage an NPC-based
timer. The NPC name may be omitted, in which case the calling NPC is used
as target.

Contrary to addtimer()/deltimer() commands which let you have many different
timers referencing different labels in the same NPC, each with their own
countdown, initnpctimer() can only have one per NPC object. But it can
trigger many labels and let you know how many were triggered already and
how many still remain.

This timer is counting up from 0 in ticks of 1/1000ths of a second each.
Upon  creating this timer, the execution will not stop, but will happily
continue onward. The timer will then invoke new execution threads at
labels "OnTimer<time>:" in the NPC object it is attached to.

To create the timer, use the initnpctimer(), which will start it running.
stopnpctimer() will pause the timer, without clearing the current tick,
while startnpctimer() will let the paused timer continue.

By default timers do not have a RID attached, which lets them continue
even if the player that started them logs off. To attach a RID to a timer,
you can either use the optional "attach flag" when using
initnpctimer()/startnpctimer(), or do it manually by using attachnpctimer().
Likewise, the optional flag of stopnpctimer() lets you detach any RID after
stopping the timer, and by using detachnpctimer() you can detach a RID at
any time.

Normally there is only a single timer per NPC, but as an exception, as
long as you attach a player to the timer, you can have multiple timers
running at once, because these will get stored on the players instead of
the NPC.
NOTE: You need to attach the RID before the timer _before_ you start it to
get a player-attached timer. Otherwise it'll stay a NPC timer (no effect).

If the player that is attached to the npctimer logs out, the
"OnTimerQuit:" event label of that NPC will be triggered, so you can do
the appropriate cleanup (the player is still attached when this event is
triggered).

The setnpctimer() command will explicitly set the timer to a given tick.
getnpctimer() provides timer information. Its parameter defines what type:

 0 - Will return the current tick count of the timer.
 1 - Will return 1 if there are remaining "OnTimer<ticks>:" labels in the
	 specified NPC waiting for execution.
 2 - Will return the number of times the timer has triggered and will
	 trigger an "OnTimer<tick>:"  label in the specified NPC.

Example 1:

	<NPC Header> {
		// We need to use attachnpctimer() because the mes command below
		// needs RID attach
		attachnpctimer();
		initnpctimer();
		npctalk("I cant talk right now, give me 10 seconds");
		end;
	OnTimer5000:
		npctalk("Ok 5 seconds more");
		end;
	OnTimer6000:
		npctalk("4");
		end;
	OnTimer7000:
		npctalk("3");
		end;
	OnTimer8000:
		npctalk("2");
		end;
	OnTimer9000:
		npctalk("1");
		end;
	OnTimer10000:
		stopnpctimer();
		mes("[Man]");
		mes("Ok we can talk now");
		detachnpctimer();
		// and remember attachnpctimer() and detachnpctimer() can only be used
		// while the NPC timer is not running!
	}

Example 2:

	OnTimer15000:
		npctalk("Another 15 seconds have passed.");

		// You have to use initnpctimer() instead of setnpctimer(0).
		// This is equal to setnpctimer(0); startnpctimer();.
		// Alternatively, you can also insert another 'OnTimer15001:' label
		// so that the timer won't stop.
		initnpctimer();
		end;

	// This OnInit label will run when the script is loaded, so that the
	// timer is initialized immediately as the server starts. It is
	// dropped back to 0 every time the NPC says something, so it will
	// cycle continuously.
	OnInit:
		initnpctimer();
		end;

Example 3:

	mes("[Man]");
	mes("I have been waiting "+(getnpctimer(0)/1000)+" seconds for you.");
	// We divide the timer returned by 1000 to convert milliseconds to
	// seconds.
	close();

Example 4:

	mes("[Man]");
	mes("Ok, I will let you have 30 more seconds...");
	close2();
	setnpctimer(getnpctimer(0)-30000);
	// Notice the close2(). If there were a next() there the timer would
	// be changed only after the player pressed the next() button.
	end;

---------------------------------------

*sleep(<milliseconds>)
*sleep2(<milliseconds>)
*awake("<NPC name>")

These commands are used to control the pause of a NPC.
sleep() and sleep2() will pause the script for the given amount of
milliseconds.
awake() is used to cancel a sleep(). When awake() is called on a NPC it will run
as if the sleep timer ran out, and thus making the script continue. sleep()
and sleep2() basically do the same, but the main difference is that sleep()
will not keep the rid, while sleep2() does.

Examples:
	// This will pause the script for 10 seconds and ditch the RID
	// (so no player is attached anymore)
	sleep(10000);
	// Pauses the script for 5 seconds, and continue with the RID attached.
	sleep2(5000);
	//Cancels any running sleep timers on the NPC 'NPC'.
	awake("NPC");

---------------------------------------

*progressbar("<color>", <seconds>)
*progressbar_unit("<color>", <seconds>{, <GID>})

This command works almost like sleep2(), but displays a progress bar above
the head of the currently attached character (like cast bar). Once the
given amount of seconds passes, the script resumes. If the character moves
while the progress bar progresses, it is aborted and the script ends. The
color format is in RGB (0xRRGGBB). The color is currently ignored by the
client and appears always green.

progressbar_unit works only for PACKETVER >= 20130821
The progressbar will show on the given unit id but it will not
put the unit in timeout (the progressbar would be just an animation).
if GID is not given use the attached player.

---------------------------------------
//=====================================
5.1 - End of Time-related commands
//=====================================
---------------------------------------

*loudhailer("<message>"{, "<color>"})

Announces a colored text in '<char_name> Shouts : <message>' format.
<color> must be a string in "RRGGBB" format. If <color> is omitted,
white ("FFFFFF") will be used.
This command is specially created for the Megaphone_ item (12221),
but will work in NPCs, too.

---------------------------------------

*announce("<text>", <flag>{, <fontColor>{, <fontType>{, <fontSize>{, <fontAlign>{, <fontY>}}}}})

This command will broadcast a message to all or most players, similar to
@kami/@kamib GM commands.

	announce("This will be shown to everyone at all in yellow.", bc_all);

The region the broadcast is heard in (target), source of the broadcast and
the color the message will come up as is determined by the flags.

The flag values are coded as constants in doc/constants.md to make them
easier to use.

Target flags:
- bc_all:	Broadcast message is sent server-wide (default).
- bc_map:	Message is sent to everyone in the same map as the source of
			the broadcast (see below).
- bc_area:	Message is sent to players in the vicinity of the source.
- bc_self:	Message is sent only to current player.
You cannot	use more than one target flag.

Source flags:
- bc_pc:	Broadcast source is the attached player (default).
- bc_npc:	Broadcast source is the NPC, not the player attached to the
			script (useful when a player is not attached or the message
			should be sent to those nearby the NPC).
You cannot use more than one source flag.

Special flags:
- bc_yellow:Broadcast will be displayed in yellow color (default).
- bc_blue:	Broadcast will be displayed in blue color.
- bc_woe:	Indicates that this broadcast is 'WoE Information' that can
			be disabled client-side.
Due to the way client handles broadcasts, it is impossible to set both
bc_blue and bc_woe.

The optional parameters allow usage of broadcasts in custom colors,
font-weights, sizes etc. If any of the optional parameters is used,
special flag is ignored. Optional parameters may not work well (or at all)
depending on a game client used.

The color parameter is a single number which can be in hexadecimal
notation. C_ constant can also be used for color effects, see the full list
of the available ones in 'db/constants.conf' under 'C_'.

For example:
	announce("This announcement will be shown to everyone in green.", bc_all, 0x00FF00);
Will display a global announce in green. The color format is in RGB
(0xRRGGBB).

Another example:
	announce("This announcement will shown to everyone in purple.", bc_all, C_PURPLE);

In official scripts only two font-weights (types) are used:
 - normal (FW_NORMAL = 400, default),
 - bold   (FW_BOLD = 700).

Default font size is 12.

Using this for private messages to players is probably not that good an
idea, but it can be used instead in NPCs to "preview" an announce.

	// This will be a private message to the player using the NPC that
	// made the announcement
	announce("This is my message just for you", bc_blue|bc_self);

	// This will be shown on everyones screen that is in sight of the NPC.
	announce("This is my message just for you people here", bc_npc|bc_area);

---------------------------------------

*mapannounce("<map name>", "<text>", <flag>{, <fontColor>{, <fontType>{, <fontSize>{, <fontAlign>{, <fontY>}}}}}})

This command will work like announce() but will only broadcast to
characters currently residing on the specified map. The flag and optional
parameters parameters are the same as in announce(), but target and source
flags are ignored.

---------------------------------------

*areaannounce("<map name>", <x1>, <y1>, <x2>, <y2>, "<text>", <flag>{, <fontColor>{, <fontType>{, <fontSize>{, <fontAlign>{, <fontY>}}}}}})

This command works like 'announce' but will only broadcast to characters
residing in the specified x1/y1-x2/y2 rectangle on the map given. The
flags and optional parameters are the same as in announce(), but target
and source flags are ignored.

	areaannounce("prt_church", 0, 0, 350, 350, "God's in his heaven, all right with the world", 0);

---------------------------------------

*callshop("<name>", <option>)

These are a series of commands used to create dynamic shops.
The callshop() function calls an invisible shop (FAKE_NPC) as if the player
clicked on it.

For the options on callShop:
	0 = The normal window (buy, sell and cancel)
	1 = The buy window
	2 = The sell window

Example:

//Will call the shop named DaShop and opens the buy menu.
callshop("DaShop", 1);


The shop which is called by callshop() (as long as an npcshop* command is
executed from that NPC (see note 1)) will trigger the labels OnBuyItem and
OnSellitem. These labels can take over handling for relatively the buying
of items from the shop and selling the items to a shop. Via these labels
you can customize the way an item is bought or sold by a player.

In the OnBuyItem, two arrays are filled (@bought_nameid and
@bought_quantity) with information about the name id (item id) sold
and the amount sold of it. Same goes for the OnSellItem label, only the
variables are named different (@sold_nameid, @sold_quantity, @sold_refine,
@sold_attribute, @sold_identify, @sold_card1, @sold_card2, @sold_card3,
@sold_card4, @sold_opt_id1~5, @sold_opt_val1~5, @sold_opt_param1~5). 
An example on a shop comes with Hercules, and can be found
in the doc/sample/npc_dynamic_shop.txt file.

This example shows how to use the labels and their set variables to create
a dynamic shop.

Note 1: These labels will only be triggered if a npcshop* command is
executed, this is because these commands set a special data on the shop
NPC, named master_nd in the source.
The OnSellItem and OnBuyItem are triggered in the NPC whose master_nd is
given in the shop.

---------------------------------------

*npcshopitem("<name>", <item id>, <price>{, <item id>, <price>{, <item id>, <price>{, ...}}})

This command lets you override the contents of an existing NPC shop or
cashshop. The current sell list will be wiped, and only the items
specified with the price specified will be for sale.

The function returns true if shop was updated successfully, or false if not found.

Note that you cannot use -1 to specify default selling price!

---------------------------------------

*npcshopadditem("<name>", <item id>, <price>{, <item id>, <price>{, <item id>, <price>{, ...}}})

This command will add more items at the end of the selling list for the
specified NPC shop or cashshop. If you specify an item already for sell,
that item will appear twice on the sell list.

The function returns true if shop was updated successfully, or false if not found.

Note that you cannot use -1 to specify default selling price!

---------------------------------------

*npcshopdelitem("<name>", <item id>{, <item id>{, <item id>{, ...}}})

This command will remove items from the specified NPC shop or cashshop.
If the item to remove exists more than once on the shop, all instances
will be removed.

Note that the function returns true even if no items were removed. The return
value is only to confirm that the shop was indeed found.

---------------------------------------

*npcshopattach("<name>"{, <flag>})

This command will attach the current script to the given NPC shop.
When a script is attached to a shop, the events "OnBuyItem" and
"OnSellItem" of your script will be executed whenever a player buys/sells
from the shop. Additionally, the arrays @bought_nameid[],
@bought_quantity[] or @sold_nameid[] and @sold_quantity[] will be filled
up with the items and quantities bought/sold.

The optional parameter specifies whether to attach (true) or detach (false)
from the shop (the default is to attach). Note that detaching will detach
any NPC attached to the shop, even if it's from another script, while
attaching will override any other script that may be already attached.

The function returns false if the shop was not found, true otherwise.

---------------------------------------

*waitingroom("<chatroom name>", <limit>{, <event label>, <trigger>, <required zeny>, <min lvl>, <max lvl>})

This command will create a chat room, owned by the NPC object running this
script and displayed above the NPC sprite.
The maximum length of a chat room name is 60 letters.

The limit is the maximum number of people allowed to enter the chat room.
The attached NPC is included in this count. If the optional event and
trigger parameters are given, the event label
("<NPC object name>::<label name>") will be invoked as if with a donpcevent()
upon the number of people in the chat room reaching the given triggering
amount.

// The NPC will just show a box above its head that says "Hello World",
// clicking it will do nothing, since the limit is zero.
	waitingroom("Hello World", 0);

// The NPC will have a box above its head, with "Disco - Waiting Room"
// written on it, and will have 8 waiting slots. Clicking this will enter
// the chat room, where the player will be able to wait until 7 players
// accumulate. Once this happens, it will cause the NPC "Bouncer" run the
// label "OnStart".

	waitingroom("Disco - Waiting Room", 8, "Bouncer::OnStart", 7);

// The NPC will have a box above its head, with "Party - Waiting Room"
// written on it, and will have 8 waiting slots. Clicking this will allow
// a player who has 5000 zeny and lvl 50~99 to enter the chat room, where
// the player will be able to wait until 7 players accumulate. Once this
// happens, it will cause the NPC "Bouncer" run the label "OnStart".

	waitingroom("Party - Waiting Room", 8, "Bouncer::OnStart", 7, 5000, 50, 99);

Creating a waiting room does not stop the execution of the script and it
will continue to the next line.

For more examples see the 2-1 and 2-2 job quest scripts which make
extensive use of waiting rooms.

---------------------------------------

*delwaitingroom({"<NPC object name"})

This command will delete a waiting room. If no parameter is given, it will
delete a waiting room attached to the NPC object running this command, if
it is, it will delete a waiting room owned by another NPC object. This is
the only way to get rid of a waiting room, nothing else will cause it to
disappear.

It's not clear what happens to a waiting room if the NPC is disabled with
disablenpc(), by the way.

---------------------------------------

*enablewaitingroomevent({"<NPC object name>"})
*disablewaitingroomevent({"<NPC object name>"})

This will enable and disable triggering the waiting room event (see
waitingroom()) respectively. Optionally giving an NPC object name will do
that for a specified NPC object. The chat room will not disappear when
triggering is disabled and enabled in this manner and players will not be
kicked out of it. Enabling a chat room event will also cause it to
immediately check whether the number of users in it exceeded the trigger
amount and trigger the event accordingly.

Normally, whenever a waiting room was created to make sure that only one
character is, for example, trying to pass a job quest trial, and no other
characters are present in the room to mess up the script.

---------------------------------------

*getwaitingroomstate(<information type>{, "<NPC object name>"})

This function will return information about the waiting room state for the
attached waiting room or for a waiting room attached to the specified NPC
if any.

The valid information types are:

 0  - Number of users currently in the waiting room
	  $@chatmembers[] - list of user account_id
 1  - Maximum number of users allowed.
 2  - Will return 1 if the waiting room has a trigger set.
      0 otherwise.
 3  - Will return 1 if the waiting room is currently disabled.
      0 otherwise.
 4  - The Title of the waiting room (string)
 5  - Password of the waiting room, if any. Pointless, since there is no
      way to set a password on a waiting room right now.
 16 - Event name of the waiting room (string)
 32 - Whether or not the waiting room is full.
 33 - Whether the amount of users in the waiting room is higher than the
      trigger number.
 34 - Minimum Base Level to enter waiting room.
 35 - Maximum Base Level to enter waiting room.
 36 - Minimum Zeny to enter waiting room.

---------------------------------------

*warpwaitingpc("<map name>", <x>, <y>{, <number of people>})

This command will warp the amount of characters equal to the trigger
number of the waiting room chat attached to the NPC object running this
command to the specified map and coordinates, kicking them out of the
chat. Those waiting the longest will get warped first. It can also do a
random warp on the same map ("Random" instead of map name) and warp to the
save point ("SavePoint").

The list of characters to warp is taken from the list of the chat room
members. Those not in the chat room will not be considered even if they
are talking to the NPC in question. If the number of people is given,
exactly this much people will be warped.

This command can also keep track of who just got warped. It does this by
setting special variables:

$@warpwaitingpc[] is an array containing the account_id numbers of the
                  characters who were just warped.
$@warpwaitingpcnum contains the number of the character it just warped.

See also 'getpartymember' for advice on what to do with those variables.

The obvious way of using this effectively would be to set up a waiting
room for two characters to be warped onto a random PVP map for a
one-on-one duel, for example.

---------------------------------------

*kickwaitingroomall({"<NPC object name>"})

This command kicks everybody out of a specified waiting room chat.

---------------------------------------

*setmapflagnosave("<map name>", "<alternate map name>", <x>, <y>)

This command sets the 'nosave' flag for the specified map and also gives
an alternate respawn-upon-relogin point.

It does not make a map impossible to make a save point on as you would
normally think, savepoint() will still work. It will, however, make the
specified map kick the reconnecting players off to the alternate map given
to the coordinates specified.

---------------------------------------

*setmapflag("<map name>", <flag>{, <val>})

This command marks a specified map with a map flag given. Map flags alter
the behavior of the map, you can see the list of the available ones in
'doc/constants.md' under 'Mapflags'.

The map flags alter the behavior of the map regarding teleporting
(mf_nomemo, mf_noteleport, mf_nowarp), storing location when
disconnected (mf_nosave), dead branch usage (mf_nobranch), penalties
upon death (mf_nopenalty, mf_nozenypenalty), PVP behavior (mf_pvp,
mf_pvp_noparty, mf_pvp_noguild), WoE behavior (mf_gvg, mf_gvg_noparty),
ability to use skills or open up trade deals (mf_notrade, mf_novending,
mf_noskill, mf_noicewall), current weather effects (mf_snow, mf_fog,
mf_sakura, mf_leaves, mf_clouds, mf_clouds2, mf_fireworks), whether
night will be in effect on this map (mf_nightenabled) and so on.

The val optional parameter is as the mapflags variable when one exists, it
may be a number or a string depending on the mapflag in question.

---------------------------------------

*removemapflag("<map name>", <flag>)

This command removes a mapflag from a specified map.
See setmapflag() for examples of mapflags.

---------------------------------------

*getmapflag("<map name>", <flag>)

This command checks the status of a given mapflag and returns the
mapflag's state.
false means OFF, and true means ON. See setmapflag() for examples of mapflags.

---------------------------------------

*setbattleflag("<battle flag>", <value>)
*getbattleflag("<battle flag>")

Sets or gets the value of the given battle flag.
Battle flags are the flags found in the conf/map/battle/*.conf files and is
also used in Lupus' variable rates script.

Examples:

// Will set the base experience rate to 20x (2000%)
	setbattleflag("base_exp_rate", 2000);

// Will return the value of the base experience rate (when used after the
// above example, it would print 2000).
	mes(getbattleflag("base_exp_rate"));

---------------------------------------

*warpportal(<x>, <y>, "<mapname>", <x>, <y>)

Creates a warp Portal as if a acolyte class character did it.
The first x and y is the place of the warp portal on the map where the NPC
is on the mapname and second x and y is the target area of the warp portal.

Examples:

// Will create a warp portal on the NPC's map at 150,150
// leading to prontera, coords 150,180.
	warpportal(150, 150, "prontera", 150, 180);

---------------------------------------

*mapwarp("<from map>", "<to map>", <x>, <y>{, <type>, <ID>})

This command will collect all characters located on the From map and warp
them wholesale to the same point on the To map, or randomly distribute
them there if the coordinates are zero. "Random" is understood as a
special To map name and will mean randomly shuffling everyone on the same
map.

Optionally, a type and ID can be specified. Available types are:

 0 - Everyone
 1 - Guild
 2 - Party

Example:

// Will warp all members of guild with ID 63 on map prontera to alberta.
	mapwarp("prontera", "alberta", 150, 150, 1, 63);

---------------------------------------

5.2 - Guild-Related Commands
//=====================================
---------------------------------------

*maprespawnguildid("<map name>", <guild id>, <flag>)

This command goes through the specified map and for each player and
monster found there does stuff.

Flag is a bit-mask (add up numbers to get effects you want)
 1 - warp all guild members to their save points.
 2 - warp all non-guild members to their save points.
 4 - remove all monsters which are not guardian or Emperium.

Flag 7 will, therefore, mean 'wipe all mobs but guardians and the Emperium
and kick all characters out', which is what the official scripts do upon
castle surrender. Upon start of WoE, the scripts do 2 (warp out all people
not in the guild that owns the castle).

Characters not belonging to any guild will be warped out regardless of the
flag setting.

For examples, check the WoE scripts in the distribution.

---------------------------------------

*agitstart()
*agitend()
*agitstart2()
*agitend2()

These four commands will start/end War of Emperium or War of Emperium SE.

This is a bit more complex than it sounds, since the commands themselves
won't actually do anything interesting, except causing all 'OnAgitStart:'
and 'OnAgitEnd:', or 'OnAgitStart2:' and 'OnAgitEnd2:' in the case of
latter two commands, events to run everywhere, respectively. They are used
as  simple triggers to run a lot of complex scripts all across the server,
and they, in turn, are triggered by clock with an 'OnClock<time>:'
time-triggering label.

---------------------------------------

*gvgon("<map name>")
*gvgoff("<map name>")

These commands will turn GVG mode for the specified maps on and off,
setting up appropriate map flags. In GVG mode, maps behave as if during
the time of WoE, even though WoE itself may or may not actually be in
effect.

---------------------------------------

*flagemblem(<guild id>)

This command only works when run by the NPC objects which have sprite id
GUILD_FLAG (722), which is a 3D guild flag sprite. If it isn't, the data
will change, but nothing will be seen by anyone. If it is invoked in
that manner, the emblem of the specified guild will appear on the flag,
though, if any players are watching it at this moment, they will not see
the emblem change until they move out of sight of the flag and return.

This is commonly used in official guildwar scripts with a function call
which returns a guild id:

// This will change the emblem on the flag to that of the guild that owns
// "guildcastle"

	flagemblem(getcastledata("guildcastle", 1));

---------------------------------------

*guardian("<map name>", <x>, <y>, "<name to show>", <mob id>{, "<event label>"{, <guardian index>}})

This command is roughly equivalent to monster(), but is meant to be used
with castle guardian monsters and will only work with them. It will set
the guardian characteristics up according to the castle's investment
values and otherwise set the things up that only castle guardians need.

Returns the id of the mob or 0 if an error occurred.
When 'guardian index' isn't supplied it produces a temporary guardian.
Temporary guardians are not saved with the castle and can't be accessed by
guardianinfo.

---------------------------------------

*guardianinfo("<map name>", <guardian number>, <type>)

This function will return various info about the specified guardian, or -1
if it fails for some reason. It is primarily used in the castle manager
NPC.

Map name and guardian number (value between 0 and 7) define the target.
Type indicates what information to return:
 0 - visibility (whether the guardian is installed or not)
 1 - max. hp
 2 - current hp

---------------------------------------
//=====================================
5.2 - End of Guild-Related Commands
//=====================================
---------------------------------------

*npcspeed(<speed value>)
*npcwalkto(<x>, <y>)
*npcstop()

These commands will make the NPC object in question move around the map.
As they currently are, they are a bit buggy and are not useful for much
more than making an NPC move randomly around the map.

npcspeed() will set the NPCs walking speed to a specified value. As in the
@speed GM command, 200 is the slowest possible speed while 0 is the
fastest possible (instant motion). 100 is the default character walking
speed.
npcwalkto() will start the NPC sprite moving towards the specified
coordinates on the same map as it is currently on. The script proceeds
immediately after the NPC begins moving.
npcstop() will stop the motion.

While in transit, the NPC will be clickable, but invoking it will cause it
to stop moving, which will make it's coordinates different from what the
client computed based on the speed and motion coordinates. The effect is
rather unnerving.

Only a few NPC sprites have walking animations, and those that do, do not
get the animation invoked when moving the NPC, due to the problem in the
NPC walking code, which looks a bit silly. You might have better success
by defining a job-sprite based sprite id in 'db/mob_avail.txt' with this.

---------------------------------------

*movenpc("<NPC name>", <x>, <y>{, <dir>})

This command looks like the npcwalktoxy function, but is a little different.

While npcwalktoxy just makes the NPC 'walk' to the coordinates given
(which sometimes gives problems if the path isn't a straight line without
objects), this command just moves the NPC. It basically warps out and in
on the current and given spot. Direction can be used to change the NPC's
facing direction.

Example:

// This will move Bugga from to the coordinates 100,20 (if those
// coordinates are legit).
	movenpc("Bugga", 100, 20);

---------------------------------------

*navigateto("<map>"{,<x>,<y>,<flag>,<hide_window>,<monster_id>,<char_id>});

Generates a navigation for attached or specified character. Requires client
2011-10-10aRagEXE or newer.

The flag specifies how the client will calculate the specific route.

Valid flags are:
 NAV_NONE - No services
 NAV_AIRSHIP_ONLY - Airship only
 NAV_SCROLL_ONLY - Scroll only
 NAV_AIRSHIP_AND_SCROLL - Airship and Scroll
 NAV_KAFRA_ONLY - Kafra only
 NAV_KAFRA_AND_AIRSHIP - Kafra and Airship
 NAV_KAFRA_AND_SCROLL - Kafra and Scroll
 NAV_ALL - All services

When flag is not specified, the default value is NAV_KAFRA_AND_AIRSHIP.

The hide_window specifies whether to display (0) or hide (1) the navigation window.
By default the window is hidden.

You can specify the monster_id in combination with a mapname to make the
navigation system tell you, that you have reached the desired mob.

Note:
The client requires custom monster spawns be in the navigation file
for using the embedded client Navigation feature to work properly. In this
instance sending the player to the map where the monster spawns is a simpler
solution rather than sending the map and the monster_id.

---------------------------------------
//=====================================
6 - Other Commands
//=====================================
---------------------------------------

*debugmes("<format string>"{, <param>{, ...}})

	@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
	@ /!\ This command is deprecated @
	@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

This command will print a message in the server console (map-server window),
after applying the same format-string replacements as sprintf(). It will not be
displayed anywhere else. Returns true on success.

Example:

	// Displays "NAME has clicked me!" in the map-server window.
	debugmes("%s has clicked me!", strcharinfo(PC_NAME));

	debugmes("\033[0;32mHello World"); // supports ANSI escape sequences

---------------------------------------

*consolemes("<type>", "<format string>"{,<param>{, ...}})

This command will print a message in the server console (map-server window),
after applying the same format-string replacements as sprintf(). It will not be
displayed anywhere else. Returns true on success.

List of available <type> are:
	CONSOLEMES_DEBUG   = 0
	CONSOLEMES_ERROR   = 1
	CONSOLEMES_WARNING = 2
	CONSOLEMES_INFO    = 3
	CONSOLEMES_STATUS  = 4
	CONSOLEMES_NOTICE  = 5

Example:

	// Displays "NAME has clicked me!" in the map-server window.
	consolemes(CONSOLEMES_DEBUG, "%s has clicked me!", strcharinfo(PC_NAME));

	consolemes(CONSOLEMES_DEBUG, "\033[0;32mHello World"); // supports ANSI escape sequences

---------------------------------------

*logmes("<message>"{, <log type>})

This command will write the message given to the map server log files, as
specified in 'conf/map/logs.conf'. If SQL logging is enabled, the message will
go to the specified log table. If logs are not enabled, nothing will happen.

Log types are:

LOGMES_NPC - log to the 'npclog' table (Default)
LOGMES_ATCOMMAND - log to the 'atcommandlog' table

Example:

    logmes("foobar");
    logmes("foobar", LOGMES_ATCOMMAND);

---------------------------------------

*globalmes("<message>"{, "<NPC name>"})

This command will send a message to the chat window of all currently
connected characters.

If NPC name is specified, the message will be sent as if the sender would
be the NPC with the said name.

---------------------------------------

*channelmes("<#channel>", "<message>")

This command will send a message to the specified chat channel.

The sent message will not include any character's names.

For special channels, such as #map and #ally, the attached RID's map or guild
will be used.

If the channel doesn't exist (or, in the case of a character-specific channel,
no RID is attached), false will be returned. In case of success, true is
returned.

---------------------------------------

*addchannelhandler("<#channel>", "<NPC::OnEvent>")

This command will trigger the specified event every time a player
talks in the specified channel, with said player as attached rid.
It assigns the message to @channelmes$

OnChannelMessage:
	channelmes("#chan", "Echo: " + @channelmes$);
	end;

OnInit:
	addchannelhandler("#chan", "NPC::OnChannelMessage");

---------------------------------------

*removechannelhandler("<#channel>", "<NPC::OnEvent>")

Removes a channel handler added by addchannelhandler()

---------------------------------------
*rand(<number>{, <number>})

This function returns a number ...
(if you specify one) ... randomly positioned between 0 and the number you
                         specify -1.
(if you specify two) ... randomly positioned between the two numbers you
                         specify.

rand(10)  would result in 0, 1, 2, 3, 4, 5, 6, 7, 8 or 9
rand(0, 9) would result in 0, 1, 2, 3, 4, 5, 6, 7, 8 or 9
rand(2, 5) would result in 2, 3, 4 or 5

---------------------------------------

*viewpoint(<action>, <x>, <y>, <point number>, <color>)

This command will mark places on the mini map in the client connected to
the invoking character. It uses the normal X and Y coordinates from the
main map. The colors of the marks are defined using a hexadecimal number,
same as the ones used to color text in mes() output, but are written as
hexadecimal numbers in C. (They look like 0x<six numbers>.)

Action is what you want to do with a point, 1 will set it, while 2 will
clear it. 0 will also set it, but automatically removes the point after 15
seconds.
Point number is the number of the point - you can have several. If more
than one point is drawn at the same coordinates, they will cycle, which
can be used to create flashing marks.

	// This command will show a mark at coordinates X 30 Y 40, is mark
	// number 1, and will be red.

	viewpoint(1, 30, 40, 1, 0xFF0000);

This will create three points:

	viewpoint(1, 30, 40, 1, 0xFF0000);
	viewpoint(1, 35, 45, 2, 0xFF0000);
	viewpoint(1, 40, 50, 3, 0xFF0000);

And this is how you remove them:

	viewpoint(2, 30, 40, 1, 0xFF0000);
	viewpoint(2, 35, 45, 2, 0xFF0000);
	viewpoint(2, 40, 50, 3, 0xFF0000);

The client determines what it does with the points entirely, the server
keeps no memory of where the points are set whatsoever.

---------------------------------------

*cutin("<filename>", <position>)

This command will display a picture, usually an NPC illustration, also
called cutin, for the currently attached client. The position parameter
determines the placement of the illustration and takes following values:

	0 - bottom left corner
	1 - bottom middle
	2 - bottom right corner
	3 - middle of screen in a movable window with an empty title bar
	4 - middle of screen without the window header, but still movable

The picture is read from data\texture\유저인터페이스\illust, from both the
GRF archive and data folder, and is required to be a bitmap. The file
extension .bmp can be omitted. Magenta color (#ff00ff) is considered
transparent. There is no limit placed on the size of the illustrations
by the client, although loading of large pictures (about 700x700 and
larger) causes the client to freeze shortly (lag). Typically the size is
about 320x480. New illustrations can be added by just putting the new file
into the location above.

The client is able to display only one cutin at the same time and each new
one will cause the old one to disappear. To delete the currently displayed
illustration without displaying a new one, an empty file name and position
255 must be used.

	// Displays the Comodo Kafra illustration in lower right corner.
	cutin("kafra_07", 2);

	// Typical way to end a script, which displayed an illustration during a
	// dialog with a player.
	mes("See you.");
	close2();
	cutin("", 255);
	end;

---------------------------------------

*pet(<pet id>)

This command is used in all the item scripts for taming items. Running
this command will make the pet catching cursor appear on the client
connected to the invoking character, usable on the monsters with the
specified pet ID number. It will still work outside an item script.

A full list of pet IDs can be found inside 'db/pet_db.txt'

---------------------------------------

*emotion(<emotion number>{, <target>{, "<target name>"}})

This command makes an object display an emotion sprite above their own as
if they were doing that emotion. For a full list of emotion numbers, see
'doc/constants.md' under 'Emotes'. The not so obvious ones are 'e_what' (a
question mark) and 'e_gasp' (the exclamation mark).

The optional target parameter specifies who will get the emotion on top of
their head. If false (default if omitted), the NPC in current use will show
the emotion, if true, the player that is running the script will display it.

Target name parameter allows to display emotion on top of other NPC/PC
without event labels. If specified name is not found, command does nothing.

---------------------------------------

*misceffect(<effect number>)

    @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
    @ /!\ This command is deprecated @
    @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

This command, if run from an NPC object that has a sprite, will call up a
specified effect number, centered on the NPC sprite. If the running code
does not have an object ID (a 'floating' NPC) or is not running from an
NPC object at all (an item script) the effect will be centered on the
character who's RID got attached to the script, if any. For usable item
scripts, this command will create an effect centered on the player using
the item.

This command is deprecated and it should not be used in new scripts, as it is
likely to be removed at a later time. Please use specialeffect instead,
ie: specialeffect(<effect number>, <send target>, <unit id>)

---------------------------------------

*soundeffect("<effect filename>", <type>)
*soundeffectall("<effect filename>", <type>{, "<map name>"}{, <x0>, <y0>, <x1>, <y1>})

These two commands will play a sound effect to either the invoking
character only (soundeffect()) or multiple characters (soundeffectall()).
If the running code does not have an object ID (a 'floating' NPC) or is
not running from an NPC object at all (an item script) the sound will be
centered on the character who's RID got attached to the script, if any.
If it does, it will be centered on that object. (an NPC sprite)

Effect filename is the filename in a GRF. It must have the .wav extension.

It's not quite certain what the 'type' actually does, it is sent to the
client directly. It probably determines which directory to play the effect
from. It's certain that giving 0 for the number will play sound files from
'\data\wav\', but where the other numbers will read from is unclear.

The sound files themselves must be in the PCM format, and file names
should also have a maximum length of 23 characters including the .wav
extension:

soundeffect("1234567890123456789.wav", 0); // will play the soundeffect
soundeffect("12345678901234567890.wav", 0); // throws gravity error

You can add your own effects this way, naturally.

---------------------------------------

*playbgm("<BGM filename>")
*playbgmall("<BGM filename>"{, "<map name>"{, <x0>, <y0>, <x1>, <y1>}})

These two commands will play a Background Music to either the invoking
character only (playbgm()) or multiple characters (playbgmall()).

BGM filename is the filename in /BGM/ folder. It has to be in .mp3
extension, but it's not required to specify the extension in the script.

If coordinates are omitted, BGM will be broadcasted on the entire map. If
the map name is also omitted the BGM will be played for the entire server.

You can add your own BGMs this way, naturally.

---------------------------------------

*pvpon("<map name>")
*pvpoff("<map name>")

These commands will turn PVP mode for the specified maps on and off.
Beside setting the flags referred to in setmapflag(), pvpon() will also
create a PVP timer and ranking as will @pvpon GM command do.

---------------------------------------

*atcommand("<command>")

This command will run the given command line exactly as if it was typed in
from the keyboard by the player connected to the invoking character, and
that character belonged to an account which had GM level 99.

	// This will ask the invoker for a character name and then use the
	// '@nuke' GM command on them, killing them mercilessly.
	input(.@player$);
	atcommand("@nuke "+.@player$);

Use of this command is not recommended unless you know what you're
doing, since not all atcommands are intended to be used by the script
engine.

---------------------------------------

*charcommand("<command>")

This command will run the given command line exactly as if it was typed in
from the keyboard from a character that belonged to an account which had
GM level 99.

The commands can also run without an attached rid.

	// This would do the same as above, but now
	// it doesn't need a player attached by default.
	charcommand("#option 0 0 0 Roy");

Use of this command is not recommended unless you know what you're
doing, since not all atcommands are intended to be used by the script
engine.

---------------------------------------

*bindatcmd("command", "<NPC object name>::<event label>"{, <group level>, <group level char>, <log>})

This command will bind a NPC event label to an atcommand. Upon execution
of the atcommand, the user will invoke the NPC event label. Each atcommand
is only allowed one binding. If you rebind, it will override the original
binding. If group level is provided, only users of that group level or
above will be able to access the command, if not provided, everyone will
be able to access the command.
"group level char" is the minimum group level required for the label to be
used on others like a char command would, e.g. "#command "target" params",
when not provided, "group level char" defaults to 99.
"log" whether to log the usages of this command with the atcommand log
(true = log, false = no log), default is to not log.

The following variables are set upon execution:
	.@atcmd_command$      =  The name of the @command used.
	.@atcmd_parameters$[] =  Array containing the given parameters,
	                         starting from an index of 0.
	.@atcmd_numparameters =  The number of parameters defined.

Parameters are split on spaces. Multiple spaces aren't grouped together, and
will create multiple (empty) arguments.
Any leading spaces before the first parameter will be omitted.

Usage example:

When a user types the command "@test", an angel effect will be shown.

-	script	atcmd_example	FAKE_NPC,{
OnInit:
	bindatcmd("test", strnpcinfo(NPC_NAME_UNIQUE)+"::OnAtcommand");
	end;
OnAtcommand:
	specialeffect(EF_ANGEL2, AREA, playerattached());
	end;
}

Parameter splitting example:
	@mycommand
		.@atcmd_numparameters -> 0
		.@atcmd_parameters$   -> { }
	@mycommand<space><space>
		.@atcmd_numparameters -> 0
		.@atcmd_parameters$   -> { }
	@mycommand<space>foo
		.@atcmd_numparameters -> 1
		.@atcmd_parameters$   -> { "foo" }
	@mycommand<space><space>foo
		.@atcmd_numparameters -> 1
		.@atcmd_parameters$   -> { "foo" }
	@mycommand<space>foo<space>bar
		.@atcmd_numparameters -> 2
		.@atcmd_parameters$   -> { "foo", "bar" }
	@mycommand<space>foo<space><space>bar
		.@atcmd_numparameters -> 3
		.@atcmd_parameters$   -> { "foo", "", "bar" }
	@mycommand<space>foo<space>
		.@atcmd_numparameters -> 2
		.@atcmd_parameters$   -> { "foo", "" }
	@mycommand<space>foo<space><space>
		.@atcmd_numparameters -> 3
		.@atcmd_parameters$   -> { "foo", "", "" }

The called event label needs to take care of joining arguments together, in
case it expects spaces. For example:

-	script	atcmd_example	FAKE_NPC,{
OnInit:
	bindatcmd("test", strnpcinfo(NPC_NAME_UNIQUE)+"::OnAtcommand");
	end;
OnAtcommand:
	// This command expects a character name (that may contain spaces) as
	// the only parameter.
	.@name$ = "";
	for (.@i = 0; .@i < .@atcmd_numparameters; ++.@i) {
		.@name$ += (.@i > 0 ? " " : "") + .@atcmd_parameters$[.@i];
	}
	dispbottom("The specified name is: '" + .@name$ + "'");
	end;
}

---------------------------------------

*add_group_command("<command>", <group id>, <use on self>, <use on other>)

Allows to explicitly change the command permissions for a specific group.

This command bypasses group inheritance, which means groups inheriting from
the specified <group id> will NOT inherit the specified permission. You should
use add_group_command() for every group you want to give permission to.

Example:
	bindatcmd("foobar", "NPC::OnUseCommand", 99, 99, 0); // define the command
	add_group_command("foobar", 2, true, false); // allow group 2 to use @foobar
	add_group_command("foobar", 5, true, true); // allow group 5 to use @foobar and #foobar

---------------------------------------

*unbindatcmd("command")

This command will unbind a NPC event label from an atcommand.

---------------------------------------

*useatcmd("command")

    @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
    @ /!\ This command is deprecated @
    @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

This command will execute an atcommand binding on the attached RID from a
script. The three .@atcmd_***** variables will NOT be set when invoking
scripts-atcommands this way.

This command is deprecated and it should not be used in new scripts, as it is
likely to be removed at a later time. Instead, you should directly call to the
event label of the binding using timers or doevent(). For built-in commands,
atcommand() should be used instead.

---------------------------------------

*can_use_command("<command>"{, <account id>})

Checks if the attached or specified player can use the specified
atcommand and returns true or false accordingly. Works for both
built-in atcommands and custom atcommands.

---------------------------------------

*has_permission(<permission>{, <account id>})
*has_permission("<permission>"{, <account id>})

Check if the attached or specified player has the specified permission
and returns true or false accordingly. See doc/permissions.md for
details about permissions.

Valid <permission> are:

	PERM_TRADE
	PERM_PARTY
	PERM_ALL_SKILL
	PERM_USE_ALL_EQUIPMENT
	PERM_SKILL_UNCONDITIONAL
	PERM_JOIN_ALL_CHAT
	PERM_NO_CHAT_KICK
	PERM_HIDE_SESSION
	PERM_WHO_DISPLAY_AID
	PERM_RECEIVE_HACK_INFO
	PERM_WARP_ANYWHERE
	PERM_VIEW_HPMETER
	PERM_VIEW_EQUIPMENT
	PERM_USE_CHECK
	PERM_USE_CHANGEMAPTYPE
	PERM_USE_ALL_COMMANDS
	PERM_RECEIVE_REQUESTS
	PERM_SHOW_BOSS
	PERM_DISABLE_PVM
	PERM_DISABLE_PVP
	PERM_DISABLE_CMD_DEAD
	PERM_HCHSYS_ADMIN
	PERM_TRADE_BOUND
	PERM_DISABLE_PICK_UP
	PERM_DISABLE_STORE
	PERM_DISABLE_EXP
	PERM_DISABLE_SKILL_USAGE
	PERM_BYPASS_NOSTORAGE

Example:

	if (has_permission(PERM_WARP_ANYWHERE)) {
		//do something
	}

It is also possible to pass a string for plugin permissions:

	if (has_permission("show_version")) {
		//do something
	}

** Passing a string is slower than passing a constant because
   the engine has to loop through the array to find the permission.
   In most cases you should use the PERM_ constants.

---------------------------------------

*unitskilluseid(<GID>, <skill id>, <skill lvl>{, <target id>})
*unitskilluseid(<GID>, "<skill name>", <skill lvl>{, <target id>})
*unitskillusepos(<GID>, <skill id>, <skill lvl>, <x>, <y>)
*unitskillusepos(<GID>, "<skill name>", <skill lvl>, <x>, <y>)

This is the replacement of the older commands, these use the same values
for GID as the other unit* commands (See 'GID').

Skill ID is the ID of the skill, skill level is the level of the skill.
For the position, the x and y are given in the unitskillusepos.

---------------------------------------

*npcskill(<skill id>, <skill lvl>, <stat point>, <NPC level>)
*npcskill("<skill name>", <skill lvl>, <stat point>, <NPC level>)

This command causes the attached NPC object to cast a skill on the
attached player. The skill will have no cast time or cooldown. The player
must be within the default skill range or the command will fail silently.

The "stat point" parameter temporarily sets all NPC stats to the given
value, and "NPC level" is the temporary level of the NPC (used in some
skills). Neither value can be greater than the max level defined in
config, and will not work properly if the NPC has a mob sprite.

	// Casts Level 10 Heal on the attached player, calculated with
	// all stats 99 and base level 60.
	npcskill(AL_HEAL, 10, 99, 60);

---------------------------------------

*setnpcdistance(<distance>)

This command can reduce distance from where npc can be clicked.
Usefull to use from OnInit event.

	// Set distance to one tile on server load
	OnInit:
	setnpcdistance(1);

---------------------------------------

*getnpcdir({<name>})

Return current npc direction for parameter "name" or for attached npc
if it missing. If name missing and not attached npc, return -1.

Example:
	.@dir = getnpcdir();

---------------------------------------

*setnpcdir({<name>, }<direction>)

Set npc direction. If npc name missing, will be used attached npc.

Example:
	setnpcdir(DIR_WEST);

---------------------------------------

*getnpcclass({<name>})

Return npc class/sprite id for npc with given name or for attached npc.
If name missing and no attached npc, return -1.

Example:
	.@class = getnpcclass();

---------------------------------------

*day();
*night();

These two commands will switch the entire server between day and night
mode respectively. If your server is set to cycle between day and night by
configuration, it will eventually return to that cycle.

Example:

-	script	DayNight	FAKE_NPC,{
OnClock0600:
	day();
	end;
OnInit:
	// setting correct mode upon server start-up
	if (gettime(GETTIME_HOUR) >= 6 && gettime(GETTIME_HOUR) < 18)
		end;
OnClock1800:
	night();
	end;
}

This script allows to emulate the day/night cycle as the server does, but
also allows triggering additional effects upon change, like announces,
gifts, etc.
The day/night cycle set by configuration should be disabled when this
script is used.

---------------------------------------

*pcre_match("<string>", "<regex>")

The string <string> will be searched for a match to the regular expression
<regex>, and the number of matches will be returned.

An alternative way to invoke this command is to use the operators '~=' or '~!'.
The operator '~=' is exactly the same as pcre_match, while the operator '~!'
will return true if no matches were found, or false if at least a match was found.

	if (pcre_match("string", "regex"))
		mes("There was a match.");
	if ("string" ~= "regex")
		mes("There was a match.");
	if ("string" ~! "regex")
		mes("There were no matches.");

You can find more usage examples in the test script npc/custom/test.txt.

Using regular expressions is high wizardry. But with this high wizardry
comes unparalleled power of text manipulation. For an explanation of what
a regular expression pattern is, see a few web pages:

http://www.regular-expressions.info/
http://www.weitz.de/regex-coach/

Additionally, the following temporary variables will be filled (unless the
command is invoked as '~!'):

- $@regexmatchcount: The number of matches detected, including any
  parenthesized capture-groups.
- $@regexmatch$[0]: The part of <string> That matched the full <regex> pattern.
- $@regexmatch$[1 .. $@regexmatchcount]: The parts of <string> that matched
  each of the parenthesized capture-groups in <pattern>.

A capture group is a part of a regex enclosed in (parentheses) in order to
store in a variable the part of the expression that was matched by that part of
the regex. For more details, see the links above, as this is not intended to be
a regex tutorial.

---------------------------------------

*defpattern(<set number>, "<regular expression pattern>", "<event label>")
*activatepset(<set number>)
*deactivatepset(<set number>)
*deletepset(<set number>)

They will make the NPC object listen for text spoken publicly by players
and match it against regular expression patterns, then trigger labels
associated with these regular expression patterns.

Patterns are organized into sets, which are referred to by a set number.
You can have multiple sets patterns, and multiple patterns may be active
at once. Numbers for pattern sets start at 1.

defpattern() will associate a given regular expression pattern with an
event label. This event will be triggered whenever something a player says
is matched by this regular expression pattern, if the pattern is currently
active.

activatepset() will make the pattern set specified active. An active
pattern will enable triggering labels defined with defpattern(), which
will not happen by default.
deactivatepset() will deactivate a specified pattern set. Giving -1 as a
pattern set number in this case will deactivate all pattern sets defined.

deletepset() will delete a pattern set from memory, so you can create a
new pattern set in its place.

For an example of this in use, see doc/sample/npc_test_pcre.txt

With this you could, for example, automatically punish players for asking
for Zeny in public places, or alternatively, automatically give them Zeny
instead if they want it so much.

---------------------------------------

*pow(<number>, <power>)

    @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
    @ /!\ This command is deprecated @
    @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

Returns the result of the calculation.

Example:
	.@i = pow(2, 3); // .@i will be 8

This command is deprecated and it should not be used in new scripts, as it is
likely to be removed at a later time. Please use the exponentiation operator,
ie: (2 ** 3) instead of pow(2, 3)

---------------------------------------

*log10(<number>)

Returns log base 10 of the number.

Note: The value is truncated to integer.

Example:
	.@i = log10(100); // .@i will be 2

---------------------------------------

*sqrt(<number>)

Returns square-root of number.

Note: The value is truncated to integer.

Example:
	.@i = sqrt(25); // .@i will be 5

---------------------------------------

*distance(<x0>, <y0>, <x1>, <y1>)

Returns distance between 2 points.

Note: When Hercules is configured to use circular areas, the Euclidean distance
is returned, otherwise the Chebyshev distance. The value is truncated to
integer.

Example:
	.@i = distance(100, 200, 101, 202);

---------------------------------------

*min(<number>{, <number>...<number>})
*max(<number>{, <number>...<number>})

Returns the smallest (or biggest) from the set of given numbers.

Example:
	.@minimum = min(1, -6, -2, 8, 2); // .@minimum will be equal to -6
	.@maximum = max(0, 5, 10, 4); // .@maximum will be equal to 10
	.@level = min(BaseLevel, 70); // .@level will be the character's base level, capped to 70

---------------------------------------

*cap_value(<number>, <min>, <max>)

Returns the number but capped between <min> and <max>.

Example:
	// capped between 0 ~ 100
	.@value = cap_value(10, 0, 100);   // .@value will be equal to 10
	.@value = cap_value(1000, 0, 100); // .@value will be equal to 100
	.@value = cap_value(-10, 3, 100);  // .@value will be equal to 3

---------------------------------------

*md5("<string>")

Returns the md5 checksum of a number or string.

Example:
	mes md5(12345);
	mes md5("12345"); // Will both display 827ccb0eea8a706c4c34a16891f84e7b
	mes md5("qwerty");// Will display d8578edf8458ce06fbc5bb76a58c5ca4

---------------------------------------

*swap(<variable>, <variable>)

Swap the value of 2 variables. Both sides must be same integer or string type.

Example:
	.@var1 = 111;
	.@var2 = 222;
	swap(.@var1, .@var2);
	mes("var1 = "+ .@var1); // return 222
	mes("var2 = "+ .@var2); // return 111

---------------------------------------

*query_sql("your MySQL query"{, <array variable>{, <array variable>{, ...}}})
*query_logsql("your MySQL query"{, <array variable>{, <array variable>{, ...}}})

Executes an SQL query. A 'select' query can fill array variables with up
to 128 rows of values, and will return the number of rows (the array size).

Note that query_sql() runs on the main database while query_logsql() runs
on the log database.

Example:
	.@nb = query_sql("select name, fame from `char` ORDER BY fame DESC LIMIT 5", .@name$, .@fame);
	mes("Hall Of Fame: TOP5");
	mes("1."+.@name$[0]+"("+.@fame[0]+")"); // Will return a person with the biggest fame value.
	mes("2."+.@name$[1]+"("+.@fame[1]+")");
	mes("3."+.@name$[2]+"("+.@fame[2]+")");
	mes("4."+.@name$[3]+"("+.@fame[3]+")");
	mes("5."+.@name$[4]+"("+.@fame[4]+")");

---------------------------------------

*escape_sql(<value>)

Converts the value to a string and escapes special characters so that it's
safe to use in query_sql(). Returns the escaped form of the given value.

Example:
	.@str$ = "John's Laptop";
	.@esc_str$ = escape_sql(.@name$); // Escaped string: John\'s Laptop

---------------------------------------

*setitemscript(<item id>, <"{ new item script }">{, <type>})

Set a new script bonus to the Item. Very useful for game events.
You can remove an item's itemscript by leaving the itemscript argument
empty. Returns 1 on success, or 0 on fail (item_id not found or new item
script is invalid).
Type can optionally be used indicates which script to set (default is 0):
 0 - Script
 1 - OnEquip_Script
 2 - OnUnequip_Script

Example:

setitemscript(Silver_Ring_, "{ if (isequipped(Santa's_Hat) == 0) end; if (getskilllv(AL_TELEPORT)) { skill(MC_IDENTIFY, 1); } else { skill(AL_TELEPORT, 1+isequipped(Santa's_Hat)); } }");
setitemscript(Silver_Ring_, "");

---------------------------------------

*atoi("<string>")
*axtoi("<string>")
*strtol("string", base)

These commands are used to convert strings to numbers. atoi() will
interpret given string as a decimal number (base 10), while axtoi()
interprets strings as hexadecimal numbers (base 16). strtol() lets
the user specify a base (valid range is between 2 and 36 inclusive,
or the special value0, which means auto-detection).

The atoi() and strtol() functions conform to the C functions with the same
names, and axtoi() is the same as strtol(), with a base of 16. Results are
clamped to signed 32 bit int range (INT_MIN ~ INT_MAX)

Example:

.@var = atoi("11");        // Sets .@var to 11
.@var = axtoi("FF");       // Sets .@var to 255
mes(axtoi("11"));          // Displays 17 (1 = 1, 10 = 16)
.@var = strtol("11", 10);  // Sets .@var to 11 (11 base 10)
.@var = strtol("11", 16);  // Sets .@var to 17 (11 base 16)
.@var = strtol("11", 0);   // Sets .@var to 11 (11 base 10, auto-detected)
.@var = strtol("0x11", 0); // Sets .@var to 17 (11 base 16, auto-detected because of the "0x" prefix)
.@var = strtol("011", 0);  // Sets .@var to 9 (11 base 8, auto-detected because of the "0" prefix)
.@var = strtol("11", 2);   // Sets .@var to 3 (binary 11)

---------------------------------------

*compare("<string>", "<substring>")

This command returns true when the substring is in the main string or
false otherwise. This command is not case sensitive.

Examples:

//dothis(); will be executed ('Bloody Murderer' contains 'Blood').
	if (compare("Bloody Murderer", "Blood"))
		dothis();
//dothat(); will not be executed ('Blood butterfly' does not contain 'Bloody').
	if (compare("Blood Butterfly", "Bloody"))
		dothat();

---------------------------------------

*strcmp("<string>", "<string>")

This command compares two strings and is similar to strcmp in C.

Return Values:
	>0  : String 1 > String 2
	0  : Strings are equal
	<0 : String 1 < String 2

Examples:
	.@a = strcmp("abcdef", "ABCDEF");
	if (.@a > 0){
		mes(".@a is greater than 0."); //Output is this.
	} else {
		mes(".@a is less or equal to 0");
	}

---------------------------------------

*getstrlen("<string>")

This function will return the length of the string given as an argument.
It is useful to check if anything input by the player exceeds name length
limits and other length limits and asking them to try to input something
else.

---------------------------------------

*isstr(<argument>)

This command checks if the given <argument> is a string (1),
an integer (0) or something else (2).

Example:

    isstr(69); // outputs 0
    isstr("69"); // outputs 1

---------------------------------------

*getdatatype(<argument>)

This command returns the raw type of the given <argument>. Unlike
isstr, this command does not evaluate the argument. The returned type
is bitmasked.

types include:

	DATATYPE_NIL
	DATATYPE_STR
	DATATYPE_INT
	DATATYPE_CONST
	DATATYPE_PARAM
	DATATYPE_VAR
	DATATYPE_LABEL

Example:

	getdatatype() // DATATYPE_NIL
	getdatatype("foo") // DATATYPE_STR
	getdatatype(@foo$) // (DATATYPE_VAR | DATATYPE_STR)

---------------------------------------

*data_to_string(<data>)

Returns a string representation of the given data, similar to the .toString()
method in JavaScript.

Example:

	data_to_string(DATATYPE_VAR) // "DATATYPE_VAR"
	data_to_string(.@foo) // ".@foo"

---------------------------------------

*charisalpha("<string>", <position>)

This function will return true if the character number Position in the given
string is a letter, false if it isn't a letter but a digit or a space.
The first letter is position 0.

---------------------------------------

*charat(<string>, <index>)

Returns char at specified index. If index is out of range, returns an
empty string.

Example:

	charat("This is a string", 10); //returns "s"

---------------------------------------

*chr(<int>)

Returns a char from its ASCII value.

Example:

    chr(99); //returns "c"

---------------------------------------

*ord(<chr>)

Returns the ASCII value of char <chr>.

Example:

    ord("c"); //returns 99

---------------------------------------

*setchar(<string>, <char>, <index>)

Returns the original string with the char at the specified index set to
the specified char. If index is out of range, the original string will be
returned. Only the 1st char in the <char> parameter will be used.

Example:

	setchar("Cat", "B", 0); //returns "Bat"

---------------------------------------

*insertchar(<string>, <char>, <index>)

Returns the original string with the specified char inserted at the
specified index. If index is out of range, the char will be inserted on
the end of the string that it is closest. Only the 1st char in the <char>
parameter will be used.

Example:

	insertchar("laughter", "s", 0); //returns "slaughter"

---------------------------------------

*delchar(<string>, <index>)

Returns the original string with the char at the specified index removed.
If index is out of range, original string will be returned.

Example:

	delchar("Diet", 3); //returns "Die"

---------------------------------------

*strtoupper(<string>)
*strtolower(<string>)

Returns the specified string in it's uppercase/lowercase form.
All non-alpha characters will be preserved.

Example:

	strtoupper("The duck is blue!!"); //returns "THE DUCK IS BLUE!!"

---------------------------------------

*charisupper(<string>, <index>)
*charislower(<string>, <index>)

Returns true if character at specified index of specified string is
uppercase for charisupper() or lowercase for charislower(). Otherwise, false.
Characters not of the alphabelt will return false.

Example:

	charisupper("Hercules", 0); //returns 1

---------------------------------------

*substr(<string>, <start_index>, <end_index>)

Returns the sub-string of the specified string inclusively between the set
indexes. If indexes are out of range, or the start index is after the end
index, an empty string will be returned.

Example:

	substr("foobar", 3, 5); //returns "bar"

---------------------------------------

*explode(<dest_array>, <string>, <delimiter>)

Breaks a string up into substrings based on the specified delimiter.
Substrings will be stored within the specified string array. Only the 1st
char of the delimiter parameter will be used. If an empty string is passed
as a delimiter, the string will be placed in the array in its original
form, without any changes. Return the number of elements written to
<dest_array>.

Example:

	.@num_elements = explode(.@my_array$, "Explode:Test:1965:red:PIE", ":");
	//.@my_array$ contents will be...
	//.@my_array$[0]: "Explode"
	//.@my_array$[1]: "Test"
	//.@my_array$[2]: "1965"
	//.@my_array$[3]: "red"
	//.@my_array$[4]: "PIE"
	//.@num_elements: 5

---------------------------------------

*implode(<string_array>{, <glue>})

Combines all substrings within the specified string array into a single
string. If the glue parameter is specified, it will be inserted inbetween
each substring.

Example:
	setarray(.@my_array$[0], "This", "is", "a", "test");
	implode(.@my_array$, " "); //returns "This is a test"

---------------------------------------

*sprintf(<format>{, param{, param{, ...}}})

C style sprintf. The resulting string is returned.

The format string can contain placeholders (format specifiers) using the
following structure:

  %[parameter][flags][width]type

The following format specifier types are supported:

%%: Prints a literal '%' (special case, doesn't support parameter, flag, width)
%d, %i: Formats the specified value as a decimal signed number
%u: Formats the specified value as a decimal unsigned number
%x: Formats the specified value as a hexadecimal (lowercase) unsigned number
%X: Formats the specified value as a hexadecimal (uppercase) unsigned number
%o: Formats the specified value as an octal unsigned number
%s: Formats the specified value as a string
%c: Formats the specified value as a character (only uses the first character
    of strings)

The following format specifier types are not supported:

%n (not implemented due to safety concerns)
%f, %F, %e, %E, %g, %G (the script engine doesn't use floating point values)
%p (the script engine doesn't use pointers)
%a, %A (not supported, use 0x%x and 0x%X respectively instead)

An ordinal parameter can be specified in the form 'x$' (where x is a number),
to reorder the output (this may be useful in translated strings, where the
sentence order may be different from the original order). Example:

	// Name, level, job name
	mes(sprintf("Hello, I'm %s, a level %d %s", strcharinfo(PC_NAME), BaseLevel, jobname(Class)));

When translating the sentence to other languages (for example Italian),
swapping some arguments may be appropriate, and it may be desirable to keep the
actual arguments in the same order (i.e. when translating through the HULD):

	// Job name is printed before the level, although they're specified in the opposite order.
	// Name, job name, level
	mes(sprintf("Ciao, io sono %1$s, un %3$s di livello %2$d", strcharinfo(PC_NAME), BaseLevel, jobname(Class)));

The supported format specifier flags are:

- (minus): Left-align the output of this format specifier. (the default is to
  right-align the output).
+ (plus): Prepends a plus for positive signed-numeric types. positive = '+',
  negative = '-'.
(space): Prepends a space for positive signed-numeric types. positive = ' ',
  negative = '-'.  This flag is ignored if the '+' flag exists.
0 (zero): When a field width option is specified, prepends zeros for numeric
  types. (the default prepends spaces).
A field width can be specified.

	mes(sprintf("The temperature is %+d degrees Celsius", .@temperature)); // Keeps the '+' sign in front of positive values
	.@map_name$ = sprintf("quiz_%02d", .@i); // Keeps the leading 0 in "quiz_00", etc

A field width may be specified, to ensure that 'at least' that many characters
are printed. If a star ('*') is specified as width, then the width is read as
argument to the sprintf() function. This also supports positional arguments.

	sprintf("%04d", 10) // Returns "0010"
	sprintf("%0*d", 5, 10) // Returns "00010"
	sprintf("%5d", 10) // Returns "   10"
	sprintf("%-5d", 10) // Returns "10   "
	sprintf("%10s", "Hello") // Returns "     Hello";
	sprintf("%-10s", "Hello") // Returns "Hello    ";

Precision ('.X') and length ('hh', 'h', 'l', 'll', 'L', 'z', 'j', 't')
specifiers are not implemented (not necessary for the script engine purposes)

Example:
	.@format$ = "The %s contains %d monkeys";
	dispbottom(sprintf(.@format$, "zoo", 5));
	//prints "The zoo contains 5 monkeys"

	dispbottom(sprintf(.@format$, "barrel", 82));
	//prints "The barrel contains 82 monkeys"

---------------------------------------

*sscanf(<string>, <format>{, param{, param{, ...}}})

C style sscanf. All C format specifiers are supported.
More info: sscanf @ www.cplusplus.com. The number of params is only
limited by Hercules' script engine.

Example:
	sscanf("This is a test: 42 foobar", "This is a test: %d %s", .@num, .@str$);
	dispbottom(.@num + " " + .@str$); //prints "42 foobar"

---------------------------------------

*strpos(<haystack>, <needle>{, <offset>})

PHP style strpos. Finds a substring (needle) within a string (haystack).
The offset parameter indicates the index of the string to start searching.
Returns index of substring on successful search, else -1.
Comparison is case sensitive.

Example:
	strpos("foobar", "bar", 0); //returns 3
	strpos("foobarfoo", "foo", 0); //returns 0
	strpos("foobarfoo", "foo", 1); //returns 6

---------------------------------------

*replacestr(<input>, <search>, <replace>{, <usecase>{, <count>}})

Replaces all instances of a search string in the input with the specified
replacement string. By default is case sensitive unless <usecase> is set
to false. If specified it will only replace as many instances as specified
in the count parameter.

Example:
	replacestr("testing tester", "test", "dash"); //returns "dashing dasher"
	replacestr("Donkey", "don", "mon", false); //returns "monkey"
	replacestr("test test test test test", "test", "yay", false, 3); //returns "yay yay yay test test"

---------------------------------------

*countstr(<input>, <search>{, <usecase>})

Counts all instances of a search string in the input. By default is case
sensitive unless <usecase> is set to false.

Example:
	countstr("test test test Test", "test"); //returns 3
	countstr("cake Cake", "Cake", false); //returns 2

---------------------------------------

*setfont(<font>)

This command sets the current RO client interface font to one of the fonts
stored in data\*.eot by using an ID of the font. When the ID of the
currently used font is used, default interface font is used again.

	0 - Default
	1 - RixLoveangel
	2 - RixSquirrel
	3 - NHCgogo
	4 - RixDiary
	5 - RixMiniHeart
	6 - RixFreshman
	7 - RixKid
	8 - RixMagic
	9 - RixJJangu

---------------------------------------

*getfont()

This command return the player's current font.
if no player is attached it would always return a 0, which is also the default font.

---------------------------------------'
*showdigit(<value>{, <type>})

Displays given numeric 'value' in large digital clock font on top of the
screen. The optional parameter 'type' specifies visual aspects of the
"clock" and can be one of the following values:

	0 - Displays the value for 5 seconds (default).
	1 - Incremental counter (1 tick/second).
	2 - Decremental counter (1 tick/second). Does not stop at zero, but
		overflows.
	3 - Decremental counter (1 tick/second). Two digits only, stops at
		zero.

For type 1 and 2 the start value is set by using negative number of the
one intended to set (ex. -10 starts the counter at 10 seconds). Except for
type 3 the value is interpreted as seconds and formatted as time in days,
hours, minutes and seconds. Note, that the official script command does
not have the optional parameter.

	// displays 23:59:59 for 5 seconds
	showdigit(86399);

	// counter that starts at 60 and runs for 60 seconds
	showdigit(60, 3);

---------------------------------------

* The Pet AI commands

These commands will only work if the invoking character has a pet, and are
meant to be executed from pet scripts. They will modify the pet AI
decision-making for the current pet of the invoking character, and will
NOT have any independent effect by themselves, which is why only one of
them each may be in effect at any time for a specific pet. A pet may
have petloot(), petskillbonus(), petskillattack() and petskillsupport() at the
same time.

*petskillbonus(<bonus type>, <value>, <duration>, <delay>)

This command will make the pet give a bonus to the owner's stat (bonus
type - bInt, bVit, bDex, bAgi, bLuk, bStr, bSpeedRate - for a full list, see the
'doc/constants.md' under 'Bonuses / Parameter IDs').

*petrecovery(<status type>, <delay>)

This command will make the pet cure a specified status condition. The
curing actions will occur once every <delay> seconds. For a full list of
status conditions that can be cured, see the list of 'Status Changes' status
condition constants in 'doc/constants.md'

*petloot(<max items>)

This command will turn on pet looting, with a maximum number of items to
loot specified. Pet will store items and return them when the maximum is
reached or when pet performance is activated.

*petskillsupport(<skill id>, <skill level>, <delay>, <percent hp>, <percent sp>)
*petskillsupport("<skill name>", <skill level>, <delay>, <percent hp>, <percent sp>)

This will make the pet use a specified support skill on the owner whenever
the HP and SP are below the given percent values, with a specified delay
time between activations. The skill numbers are as per
'db/(pre-)re/skill_db.txt'.
It's not quite certain who's stats will be used for the skills cast, the
character's or the pets. Probably, Skotlex can answer that question.

*petskillattack(<skill id>, <damage>, <number of attacks>, <rate>, <bonusrate>)
*petskillattack("<skill name>", <damage>, <number of attacks>, <rate>, <bonusrate>)

This command will make the pet cast an attack skill on the enemy the pet's
owner is currently fighting. Skill IDs and levels are as per petskillsupport().
If <number of attacks> is specified different than 0, it will make the pet cast
the skill with a fixed amount of damage inflicted and the specified number of
attacks. A value of zero uses the skill's defaults.

All commands with delays and durations will only make the behavior active
for the specified duration of seconds, with a delay of the specified
number of seconds between activations. Rates are a chance of the effect
occurring and are given in percent. 'bonusrate' is added to the normal
rate if the pet intimacy is at the maximum possible.

The behavior modified with the above mentioned commands will only be
exhibited if the pet is loyal and appropriate configuration options are
set in 'conf/map/battle.conf'.

Pet scripts in the database normally run whenever a pet of that type
hatches from the egg. Other commands usable in item scripts (see bonus())
will also happily run from pet scripts. Apparently, the pet-specific
commands will also work in NPC scripts and modify the behavior of the
current pet up until the pet is hatched again. (Which will also occur when
the character is logged in again with the pet still out of the egg.) It is
not certain for how long the effect of such command running from an NPC
script will eventually persist, but apparently, it is possible to usefully
employ them in usable item scripts to create pet buffing items.

Nobody tried this before, so you're essentially on your own here.

---------------------------------------

*bpet()

This command opens up a pet hatching window on the client connected to the
invoking character. It is used in item script for the pet incubators and
will let the player hatch an owned egg. If the character has no eggs, it
will just open up an empty incubator window.
This is still usable outside item scripts.

---------------------------------------

*makepet(<pet id>)

This command will create a pet egg and put it in the invoking character's
inventory. The kind of pet is specified by pet ID numbers listed in
'db/pet_db.txt'. The egg is created exactly as if the character just
successfully caught a pet in the normal way.

	// This will make you a poring:
	makepet(PORING);

Notice that you absolutely have to create pet eggs with this command. If
you try to give a pet egg with getitem(), pet data will not be created by
the char server and the egg will disappear when anyone tries to hatch it.

---------------------------------------

*homshuffle()

This will recalculate the homunculus stats according to its level, of the
current invoking character.

---------------------------------------

*setcell("<map name>", <x1>, <y1>, <x2>, <y2>, <type>, <flag>)

Each map cell has several 'flags' that specify the properties of that cell.
These include terrain properties (walkability, shootability, presence of
water), skills (basilica, land protector, ...) and other (NPC nearby, no
vending, ...).
Each of these can be 'on' or 'off'. Together they define a cell's behavior.

This command lets you alter these flags for all map cells in the specified
(x1,y1)-(x2,y2) rectangle.
'type' defines which flag to modify. Possible options include cell_walkable,
cell_shootable, cell_basilica. For a full list, see 'doc/constants.md'.
'flag' can be false (clear flat) or true (set flag).

Example:

	setcell("arena", 0, 0, 300, 300, cell_basilica, true);
	setcell("arena", 140, 140, 160, 160, cell_basilica, false);
	setcell("arena", 135, 135, 165, 165, cell_walkable, false);
	setcell("arena", 140, 140, 160, 160, cell_walkable, true);

This will add a makeshift ring into the center of the map. The ring will
be surrounded by a 5-cell wide 'gap' to prevent interference from outside,
and the rest of the map will be marked as 'basilica', preventing observers
from casting any offensive skills or fighting among themselves. Note that
the wall will not be shown nor known client-side, which may cause movement
problems.

Another example:

OnBarricadeDeploy:
	setcell("schg_cas05", 114, 51, 125, 51, cell_walkable, false);
	end;
OnBarricadeBreak:
	setcell("schg_cas05", 114, 51, 125, 51, cell_walkable, true);
	end;

This could be a part of the WoE:SE script, where attackers are not allowed
to proceed until all barricades are destroyed. This script would place and
remove a nonwalkable row of cells after the barricade mobs.

---------------------------------------

*checkcell("<map name>", <x>, <y>, <type>)

This command will return true or false, depending on whether the specified cell
has the 'type' flag set or not. There are various types to check, all
mimicking the server's cell_chk enumeration. The types can be found in
'doc/constants.md' under 'Cell checks'.

The meaning of the individual types can be confusing, so here's an
overview:
  - cell_chkwall/water/cliff
    these check directly for the 'terrain component' of the specified cell
  - cell_chkpass/reach/nopass/noreach
    passable = not wall & not cliff, reachable = passable
    wrt. no-stacking mod
  - cell_chknpc/basilica/landprotector/novending/nochat
    these check for specific dynamic flags (name indicates what they do)

Example:

	mes("Pick a destination map.");
	input(.@map$);
	mes("Alright, now give me the coordinates.");
	input(.@x);
	input(.@y);
	if (!checkcell(.@map$, .@x, .@y, cell_chkpass)) {
		mes("Can't warp you there, sorry!");
		close();
	} else {
		mes("Ok, get ready...");
		close2();
		warp(.@map$, .@x, .@y);
		end;
	}

---------------------------------------

*setwall("<map name>", <x>, <y>, <size>, <dir>, <shootable>, "<name>")
*delwall("<name>")

Creates an invisible wall, an array of setcell() starting from x,y and
doing a line of the given size in the given direction. The difference with
setcell is this one update client part too to avoid the glitch problem.
Directions are the same as NPC sprite facing directions: (DIR_ constants).

---------------------------------------

*readbook(<book id>, <page>)

This will open a book item at the specified page.

---------------------------------------

*rodex_sendmail(<char id>, "<sender name>", "<title>", "<body>"{, <zeny>{, <item1>, <amount1>{, <item2>, <amount2>{, <item3>, <amount3>{, <item4>, <amount4>{, <item5>, <amount5>}}}}}})
*rodex_sendmail2(<char id>, "<sender name>", "<title>", "<body>"{, <zeny>{, <item1>, <amount1>, <refine1>, <attribute1>, <card0_1>, <card1_1>, <card2_1>, <card3_1>{,<item2>, <amount2>, <refine2>, <attribute2>, <card0_2>, <card1_2>, <card2_2>, <card3_2>{,<item3>, <amount3>, <refine3>, <attribute3>, <card0_3>, <card1_3>, <card2_3>, <card3_3>{,<item4>, <amount4>, <refine4>, <attribute4>, <card0_4>, <card1_4>, <card2_4>, <card3_4>{,<item5>, <amount5>, <refine5>, <attribute5>, <card0_5>, <card1_5>, <card2_5>, <card3_5>}}}}}})

*rodex_sendmail_acc(<account id>, "<sender name>", "<title>", "<body>"{, <zeny>{, <item1>, <amount1>{, <item2>, <amount2>{, <item3>, <amount3>{, <item4>, <amount4>{, <item5>, <amount5>}}}}}})
*rodex_sendmail_acc2(<account id>, "<sender name>", "<title>", "<body>"{, <zeny>{, <item1>, <amount1>, <refine1>, <attribute1>, <card0_1>, <card1_1>, <card2_1>, <card3_1>{,<item2>, <amount2>, <refine2>, <attribute2>, <card0_2>, <card1_2>, <card2_2>, <card3_2>{,<item3>, <amount3>, <refine3>, <attribute3>, <card0_3>, <card1_3>, <card2_3>, <card3_3>{,<item4>, <amount4>, <refine4>, <attribute4>, <card0_4>, <card1_4>, <card2_4>, <card3_4>{,<item5>, <amount5>, <refine5>, <attribute5>, <card0_5>, <card1_5>, <card2_5>, <card3_5>}}}}}})

This will send a mail using the RoDEX mail system, in newer clients the message will be marked as a NPC mail (that you can't reply).
If items and zeny are specified, they will be added as attachments to the message.
For examples of usage, see /doc/sample/npc_rodex.txt

rodex_sendmail2 and rodex_sendmail_acc2 are more flexible versions.
Check getitem2 command for more information of the extra parameters.

7 - Instance-Related Commands
//=====================================
---------------------------------------

*instance_create("<instance_name>", <owner_id>{, <owner_type>})

Creates an instance using the name "<instance_name>" for the <owner_id> of
<owner_type> (when not provided, defaults to IOT_PARTY). Most instance_*
commands are used in conjunction with this command and depend on the
ID this command returns.

Valid <owner_type> values:
- IOT_NONE  (0) - <owner_id> can be any arbitrary number.
- IOT_CHAR  (1) - <owner_id> is account ID.
- IOT_PARTY (2) - <owner_id> is party ID.
- IOT_GUILD (3) - <owner_id> is guild ID.

Example:
	// Store the Party ID of the invoking character.
	.@party_id = getcharid(CHAR_ID_PARTY);

	// Attempt to create an instance using that party ID.
	.@id = instance_create("Endless Tower", .@party_id);
	if (.@id == -1) { // Invalid type - not used anymore
		// ...
	} else if (.@id == -2) { // Invalid Party ID
		// ...
	} else if (.@id == -4) { // Already exists
		// ...
	} else if (.@id < 0) { // Unspecified error while queuing instance.
		// ...
	}

---------------------------------------

*instance_destroy({<instance id>})

Destroys instance with the ID <instance id>. If no ID is specified, the
instance the script is attached to is used. If in the end no instance_id,
is found the command halts the script execution.

---------------------------------------

*instance_attachmap("<map name>", <instance id>{, <use base name>{, "<new map name>"}})

Attaches the map "<map name>" to the instance specified with
<instance id>. The optional parameter specifies, whether a map requires
emulation for instancing (true) or not (false = default). if use base name is specified,
and "<new map name>" too the server will instance the map under the "<new map name>",
name.

Returns the resulting map name on success or an empty string on failure.

Example:
	instance_attachmap("prontera", .@instance_id, true, "via");
^ the above creates a instance (or clone) of prontera, on a map called "via"

---------------------------------------

*instance_detachmap("<map name>"{, <instance id>})

Detach the map "<map name>" to the instance with the <instance id>. If no
ID is specified, the instance the script is attached to is used. If in the
end no instance_id is found the command halts the script execution.

---------------------------------------

*instance_init(<instance id>)

Initializes the instance given by <instance id>. This copies all NPCs from
the source maps to the instanced maps.

---------------------------------------

*instance_announce(<instance id>, "<text>", <flag>{, <fontColor>{, <fontType>{, <fontSize>{, <fontAlign>{, <fontY>}}}}})

Works like announce, but has the <instance id> parameter. If instance id
is -1, the instance the script is attached to is used. If in the
end no instance_id is found the command halts the script execution.

---------------------------------------

*instance_attach(<instance id>)

Attaches the current script to the instance given by <instance id>.

---------------------------------------

*instance_npcname("<npc name>"{, <instance id>})

is found the command halts the script execution.

---------------------------------------

*has_instance("<map name>"{, <instance id>})

Checks whether or not the given map belongs to specified instance. If no
ID is specified, the instance the script is attached to is used. If the
script is not attached to an instance, it'll try to check whether the,
player attached to the script possesses an instance with a map matching
"<map name>". If in the end no instance_id is found the command halts the,
script execution.

Returns name of the instanced map on success, otherwise an empty string.

---------------------------------------

*has_instance2("<map name>")

Same as has_instance, with exception it returns the instance id of the map,
as long as the user is assigned to a instance containing that map.
It will return -1 upon failure, valid instance ids are >= 0.

---------------------------------------

*instance_id()

Retrieves the instance id of the script it is being run on.

---------------------------------------

*instance_warpall("<map name>", <x>, <y>{, <instance id>})

coordinates. If no ID is specified, the instance the script is attached to
is used. If in the end no instance_id is found the command halts the,
script execution.

---------------------------------------

*instance_set_timeout(<alive timeout>, <idle timeout>{, <instance id>})

Sets the timeout values for an instance given by <instance id>. If no ID
is specified, the instance the script is attached to is used. If in the end,
no instance_id is found the command halts the script execution.

Parameter <alive timeout> specifies the total amount of time the instance
will exist. Parameter <idle timeout> specifies how long players have, when
they are outside of the instance, until it is destroyed.

Both timeout values are in seconds.

---------------------------------------

*instance_check_party(<party id>{, <amount>{, <min>{, <max>}}})

This function checks if a party meets certain requirements, returning true if
all conditions are met and false otherwise. It will only check online
characters.

amount - number of online party members (default is 1).
min    - minimum level of all characters in the party (default is 1).
max    - maximum level of all characters in the party (default is max
         level in conf).

Example:

if (instance_check_party(getcharid(CHAR_ID_PARTY), 2, 2, 149)) {
	mes("Your party meets the Memorial Dungeon requirements.");
	mes("All online members are between levels 1-150 and at least two are online.");
	close();
} else {
	mes("Sorry, your party does not meet the requirements.");
	close();
}

---------------------------------------

*instance_check_guild(<guild_id>{, <amount>{, <min>{, <max>}}})

This function checks if a guild meets certain requirements, returning true if
all conditions are met and false otherwise. it will only check online characters.

		close();
	} else {
		mes("Sorry, your guild does not meet the requirements.");
		close();
	}

---------------------------------------
*instance_set_respawn(<map_name>, <x>, <y>{, <instance_id>})

Updates the 'reload spawn' position of a instance,
that is where players in the instance are sent to upon @reloadscript,
uses the npc instance (if any) when instance_id is not provided,
handy to update a instance's progress so that when/if @reloadscript happens
the damage to the players progress is reduced.
It is most effective when used with instance variables (which are @reloadscript persistent)

If a player warps into a instance before this command has been used,
it will use the player's warp destination as the initial respawn point,
it can of course be modified by using this script command at any point.

---------------------------------------
*instance_mapname("<map name>"{, <instance id>})

Returns the unique name of the instanced map. If no instance ID is specified,
the instance the script is attached to is used. If the script is not attached to
an instance, the instance of the currently attached player's party is used. If
that fails, the command returns an empty string instead.

*waitingroom2bg_single(<battle group>, "<mapname>", <x>, <y>, "<npc name>")

Adds the first waiting player from the chat room of given NPC to an
existing battleground group and warps it to specified coordinates on given
map.

---------------------------------------

*waitingroom2bg("<mapname>", <x>, <y>, "<On Quit Event>", "<On Death Event>"{, "<npc name>"})

<Mapname> and X Y coordinates refer to where the "respawn" base is, where
the player group will respawn when they die.
<On Quit Event> refers to an NPC label that attaches to the character and
is run when they relog.
<On Death Event> refers to an NPC label that attaches to the character and
is run when they die. Can be "" for empty.

If "-" is supplied for <mapname>, this will remove the 1 second automatic
respawn on the battleground map. This allows for better manipulation of
<On Death Event>. The player will have to be warped to desired location
at the end of <On Death Event>.

Unlike the prior command, the latter will attach a GROUP in a waiting room
to the battleground, and sets the array $@arenamembers[0] where 0 holds
the IDs of the first group, and 1 holds the IDs of the second.

If the option parameter is left out, the waiting room of the current NPC
is used.

Example:
	// Battle Group will be referred to as $@KvM01BG_id1, and when they
	// die, respawn at bat_c01,52,129.
	$@KvM01BG_id1 = waitingroom2bg("bat_c01", 52, 129, "KvM01_BG::OnGuillaumeQuit", "KvM01_BG::OnGuillaumeDie");
	end;

----------------------------------------

*bg_team_setxy(<Battle Group ID>, <x>, <y>)

Update the respawn point of the given battle group to x, y on the same
map. The <Battle Group ID> can be retrieved using getcharid(CHAR_ID_BG).

	bg_team_setxy(getcharid(CHAR_ID_BG), 56, 212);
	mapannounce("bat_a01", "Group [1] has taken the work shop, and will now respawn there.", bc_map, 0xFFCE00);
	end;

----------------------------------------

*bg_warp(<Battle Group>, "<Mapname>", <x>, <y>)

Similar to warp command.
Place all members of <Battle Group> at <mapname> at x y.

Example:
	//place the battle group one for Tierra Gorge at starting position.
	bg_warp($@TierraBG1_id1, "bat_a01", 352, 342);
	end;

----------------------------------------

*bg_monster(<Battle Group>, "<map name>", <x>, <y>, "<name to show>", <mob id>, "<event label>")

Similar to monster() script command.
Spawn a monster with allegiance to the given battle group.
Does not allow for the summoning of multiple monsters.
Monsters are similar to that in War of Emperium, in that the specified
Battle group is considered friendly.

Example:
	// It can be used in two different ways.
	bg_monster($@TierraBG1_id2, "bat_a01", 167, 50, "Food Depot", OBJ_B, "Feed Depot#1::OnMyMobDead");
	end;

	// Alternatively, you can set an ID for the monster using "set".
	// This becomes useful when used with the command below.
	$@Guardian_3 = bg_monster($@TierraBG1_id2, "bat_a01", 268, 204, "Guardian", B_S_GUARDIAN, "NPCNAME::OnMyMobDead");
	end;

----------------------------------------

*bg_monster_set_team(<GID>, <Battle Group>)

This command will change the allegiance if a monster in a battle ground.
GID can be set when spawning the monster via the bg_monster() command.

Example:

OnEnable:
	mapannounce("bat_b01", "A guardian has been summoned for Battle Group 2!", bc_map, 0xFFCE00);
	$@Guardian = bg_monster($@BG_2, "bat_a01", 268, 204, "Guardian", B_S_GUARDIAN, "NPCNAME::OnMyMobDead");
	initnpctimer();
	end;

OnTimer1000:
	stopnpctimer();
	mapannounce("bat_b01", "Erm, sorry about that! This monster was meant for Battle Group 1.", bc_map, 0xFFCE00);
	bg_monster_set_team($@Guardian, $@BG_1);
	end;

Retrieves amount of players belonging to given battle group on given map
within an specified rectangular area.

----------------------------------------

*bg_updatescore("<map_name>", <Guillaume Score>, <Croix Score>)

This command will force the update of the displayed scoreboard.
It is only usable when the map is defined as a Type 2 Battleground:
mapflag%TAB%<map_name>%TAB%battleground%TAB%2

----------------------------------------

*bg_create_team("<map_name>", <Respawn X>, <Respawn Y>)

This command will create a new BG Team.
When player dies, they will be respawned map_name,X,Y as mentioned.
If "-" is supplied for the map name, this will remove the 1 second automatic
respawn on the battleground map.

Command will return -1 if BG Creation is failed,
else it will return the BG ID(Also known as TeamID).

----------------------------------------

*bg_join_team(<Team_ID>{, <account_id>})

This command will make the attached player join to Team with ID as mentioned.
If account_id is provided, command will look for that player, instead of the attached player.

Command will return -1 if Player is not found, 0 if join is failed, 1 upon successful.

----------------------------------------

*bg_match_over("<Arena Name>"{, <Cancelled>})

This command will end the battleground Arena
(Arena Name as referred to, in conf/battlegrounds.conf)
If Cancelled is not provided, it will set the join delay, as mentioned in conf/battlegrounds.conf
else, it will just destroy the Teams and queue's.
