# The Mana World Evolved
### Custom Functions

Last Update: 2021-07-30

## About custom functions
The bulk of functions used are NPC scripts.
They are loaded by npc/scripts.conf and divide in a few blocks:

- Critical Functions
- General Purpose Framework Functions
- Pre-Loading Functions
- Main Functions
- Item Functions
- Magic Functions
- GM Commands
- Events
- Post-Loading Functions
- NPC Functions

## Critical Functions
These functions are critical, and breaking them will break several other functions,
breaking in turn several NPCs, and will probably cause the server to crash.

In other words: They are nested by NPCs, scripts and functions.

### npcmovegraph
Contains the needed utilities for walking NPCs.

#### \*initmovegraph ( )
Initializes a walking NPC

#### \*setmovegraphcmd ( fromPositionLabel, toPositionLabel [,moveChanceWeight [,moveFlags]], postCommand, ...);
```
 * This function manipulates NPC moving graph. Before calling it, make sure
 * `initmovegraph' was called. The function accepts 3-5 parameters (many times):
 * fromPositionLabel, toPositionLabel -- starting and ending position of NPC move
 * moveChanceWeight -- positive integer, represents the chance of moving in given direction. (optional)
 * moveFlags -- if .mg_flags & moveFlags != 0, move is possible. (optional)
 * postCommand -- either "moveon" (start moving to next location straight after arriving from
 *                fromPositionLabel to toPositionLabel) or a semicolon-separated set of commands
 *                ("wait 3", "emote 5" etc, see `execmovecmd') that will be executed after arrival.
 *                The commands don't have to end with ";moveon", it's executed in the end by default.
```

## Items Functions
used with callfunc(), when it was quite too much script code to be added on
item_db.conf directly. One file per item, and should be used only for the item.

## Magic Functions
The post-loader (`global_event_handler`) will load magic spells from here.
Each file is a magic spell of its own, with a couple exceptions:

### magic/config
Loaded before all magic spells.

### magic/final
Loaded after all magic spells.

## Commands
These define GM Commands.

## Events
These define annual and repeatable events. Mostly.

## Post-Loading Functions
These are mostly NPCs responsible for cleaning up the whole script and functions
interface so NPCs can be loaded after.

### Scoreboards

Contains the Leaderboards and is one of the most expensive components.

- HallOfGuild
- HallOfFortune
- HallOfLevel
- HallOfJob
- HallOfAcorns (not used)
- HallOfLethality (removed)
- HallOfAlmanach
- HallOfGame

Command: `@scoreboard` and `@scoreboards`

### Global Event Handler

Handles login events, logout events, death, assassinate, server init, clear logs,
and also handles the backbone of die() function.
