Core Module
|
||||
===========
|
||||
This module defines commonly used functions by all plugins...
|
||||
|
||||
* load (filename) - loads and evaluates a javascript file, returning the evaluated object.
|
||||
|
||||
* save (object, filename) - saves an object to a file.
|
||||
|
||||
* plugin (name, interface, isPersistent) - defines a new plugin. If
|
||||
isPersistent is true then the plugin doesn't have to worry about
|
||||
loading and saving state - that will be done by the framework. Just
|
||||
make sure that anything you want to save (and restore) is in the
|
||||
'store' property - this will be created automatically if not
|
||||
already defined. (its type is object {} )
|
||||
|
||||
* ready (function) - specifies code to be executed only when all the plugins have loaded.
|
||||
|
||||
* command (name, function) - defines a command that can be used by non-operators.
|
||||
|
||||
* locationToString(Location) - returns a bukkit Location object in string form.
|
||||
|
||||
* getPlayerObject(playerName) - returns the Player object for a named player or `self` if no name is provided.
|
||||
|
||||
Core Module - Special Variables
|
||||
===============================
|
||||
There are a couple of special javascript variables available in ScriptCraft...
|
||||
|
||||
* _plugin - The ScriptCraft JavaPlugin object.
|
||||
* server - The Minecraft Server object.
|
||||
* self - the current player.

events Module
|
||||
=============
|
||||
The Events module provides a thin wrapper around Bukkit's
|
||||
Event-handling API. Bukkit's Events API makes use of Java Annotations
|
||||
which are not available in Javascript, so this module provides a
|
||||
simple way to listen to minecraft events in javascript.
|
||||
|
||||
events.on() static method
|
||||
=========================
|
||||
This method is used to register event listeners.
|
||||
|
||||
Parameters
|
||||
----------
|
||||
|
||||
* eventName - A string or java class. If a string is supplied it must
|
||||
be part of the Bukkit event class name. See [Bukkit API][buk] for
|
||||
details of the many bukkit event types. When a string is supplied
|
||||
there is no need to provide the full class name - you should omit
|
||||
the 'org.bukkit.event' prefix. e.g. if the string
|
||||
"block.BlockBreakEvent" is supplied then it's converted to the
|
||||
org.bukkit.event.block.BlockBreakEvent class .
|
||||
|
||||
If a java class is provided (say in the case where you've defined
|
||||
your own custom event) then provide the full class name (without
|
||||
enclosing quotes).
|
||||
|
||||
* callback - A function which will be called whenever the event
|
||||
fires. The callback should take 2 parameters, listener (the Bukkit
|
||||
registered listener for this callback) and event (the event fired).
|
||||
|
||||
* priority (optional - default: "HIGHEST") - The priority the
|
||||
listener/callback takes over other listeners to the same
|
||||
event. Possible values are "HIGH", "HIGHEST", "LOW", "LOWEST",
|
||||
"NORMAL", "MONITOR". For an explanation of what the different
|
||||
priorities mean refer to bukkit's [Event API Reference][buk2].
|
||||
|
||||
Returns
|
||||
-------
|
||||
An org.bukkit.plugin.RegisteredListener object which can be used to
|
||||
unregister the listener. This same object is passed to the callback
|
||||
function each time the event is fired.
|
||||
|
||||
Example:
|
||||
------
|
||||
The following code will print a message on screen every time a block is broken in the game
|
||||
|
||||
events.on("block.BlockBreakEvent", function(listener, evt){
|
||||
echo (evt.player.name + " broke a block!");
|
||||
});
|
||||
|
||||
To handle an event only once and unregister from further events...
|
||||
|
||||
events.on("block.BlockBreakEvent", function(listener, evt){
|
||||
print (evt.player.name + " broke a block!");
|
||||
evt.handlers.unregister(listener);
|
||||
});
|
||||
|
||||
To unregister a listener *outside* of the listener function...
|
||||
|
||||
var myBlockBreakListener = events.on("block.BlockBreakEvent",function(l,e){ ... });
|
||||
...
|
||||
var handlers = org.bukkit.event.block.BlockBreakEvent.getHandlerList();
|
||||
handlers.unregister(myBlockBreakListener);
