Allows to report access to removed entities instead of crashing.

I did this patch quite a while ago. Big thx to Stefan Beller for
"rebasing" it.
|

Now we do not have two character.cpp files in the repository.

While on it I replaced the id usage in the server with the usage of the
AttributeInfo directly.
Next steps:
- Dehardcode the core attribute ids and store their
attributeinfos somewhere in AttributeManager (for now i simply
wrapped the ids with getAttributeInfo().
- Move AttributeInfo out of AttributeManager to shorten the usage + to
allow using a pointer in ModifierLocation without forward declaring
it.

This removes support for skills. The plan is to allow to implement the skills
as they were implemented before via attributes. This adds a lot more
flexibility to the server creators while also removing the confusion about
skills and attributes.
So this change does:
- Remove the skillmanager with all its calls, the skill xml file, etc
- Move exp giving to the script engine:
--> Allows to implement the old behaviour (and more) in the scripts
- Remove the exp tag from the monster definition:
+ Since the server itself does not require it anymore it feels wrong to
require it for EVERY monster. TODO: Add a system to add properties to the
monsters/items.xml which allow defining things like the exp and allows to
read the value from the script engine.
+ Small drawback, but it should not be hard to implement this property
system.
- Drop the level networking and calculation.
+ level calculation will happen via the attribute system later but i would
prefer to do this in a seperate patch since this patch already got longer
than expected especially since this requires to make setting correction
points and available status points scriptable.
+ The level would be simply set as a attribute, the int number of it will be
the level, the remaining digits will be the % number till the next levelup.
- NOT remove any existing skill tables in the database update scripts.
+ There is no way to move them into the attribute table in a unified way
(there are too many different way they could have been used). So server
admins have to care about moving theirs skills to attributes themselves.
+ Keeping the old tables does not hurt for existing databases. So removing
does not give any advantage/is required anyway. The now obsolote info
about the EXP transaction is not removed for updated databases either.
(The update script basically only bumps the version number without doing
anything else.
- bump the network protocol version --> old clients won't be able to connect.
- bump the database version --> serveradmins need to update their db.

I did not adapt the scripts yet since we need some special handling for
the attributes which are required by the server directly. So you still
have to use the ids for those. I will change that later.
In the future I want to use the AttributeInfo class instead of the int
id everywhere possible. So I did a small start on that too.

Each ability can now define a cooldown that prevents the player from
using other abilities for a while. The time of this cooldown can be set
to any attribute. The modified value of the attribute is the value of
the cooldown in game ticks. The cooldown will be automatically started
if the ability has `autoconsume` set to true. Otherwise a script has to
call entity:cooldown_ability(ability).

Only moved a single script function to a member for now, will do others
in a separate commit.

I did not really care too much about staying consistent with the use of
static_casts to Actors since they are only temporary anyway until Actor
is a component too.
|
|
A CharacterData was created as a proxy class in order to allow using the
old serialization method.
|
|
Things done:
- Allowed to create new Attributes outside of the protected scope of Being
- Moved Monster to MonsterComponent
- Some minor cleanup in the Attribute setting code of monsters

This should allow to finally call functions to lua without having to care
about working around situations where a lua call causes a c++ call which
needs to call to lua again.
Tested against the source of tales repository data.
|
|
Use lua_pushliteral and lua_pushlstring instead of lua_pushstring, which
avoids Lua having to determine the length of the string.
|
|
|
|
It wasn't really adding anything since errors raised using luaL_error
are already logged anyway.

- Made the current charge being saved.
- Added script binds:
- chr_set_special_recharge_speed
- chr_get_special_recharge_speed
- chr_set_special_mana
- chr_get_special_mana
- get_special_info
- Added special info lua class. Functions:
- name
- needed_mana
- rechargeable
- on_use
- on_recharged
- category
Further the engine no longer sets charge to 0 after using of specials
this allows more flexbilillity (like failing specials).
Changes on the xml database:
- recharge renamed to rechargeable (needed by client and server)
- needed - the needed mana to trigger a special (server only)
- rechargespeed - the defailt recharge speed in mana per tick (server only)
- target - the type of target (either being or point) (server and client)
I also made the lua engine pushing nil instead of a 0 light userdata when
the pointer was 0.
Database update needed.
Change is tested.

Rather than wrapping NPC functions up in coroutines in the Lua side, they
are now managed on the C++ side as "script threads", which are essentially
the same thing.
The main purpose is that the server can now know whether any of these long
running script interactions are still active, which will probably be useful
when adding the ability to reload scripts.

The new function 'checkCurrentMap' will raise an error when no current map has
been set, eliminating the need to do custom error handling all over the place.
This also fixes several functions that would otherwise have simply crashed
when there was no current map.
Also cleaned up some "empty string parameter" checks.

It's a bit embarrassing the way this has gotten out of hand. The error
checking was inconsistent, and in some cases wrong.
A host of new helper functions, starting with 'check' rather than 'get',
perform error handling on function arguments (they will not return when
encountering an error).

Item and monster classes could already be identified by either their id or
their name. Now the explicit values returned by 'get_item_class' and
'get_monster_class' can also be used as parameter.
In addition the above two getters learned to understand all three types of
parameter as well, rather than only supporting a name.

Based on a templated helper class, MapObject references in Lua scripts are now
full user data objects. Using the '__index' member of their metatable, a
library is associated with it so that member functions can be called directly
on the object.

inventory.
It permits to open a sell box with every items in the player inventory
as requested by Striker.
Also added different return value support to both the buy selling functions,
and made fixes where relevant.
The test.lua script will be upgraded to show examples in a next commit.
What's left to be done is to fix the inventory handling for both selling
functions. (Sigh...)
