The load() function is used by ScriptCraft at startup to load all of

the javascript modules and data. You normally wouldn't need to call
|
||||
this function directly. If you put a javascript file anywhere in the
|

craftbukkit/js-plugins directory tree it will be loaded automatically
|
||||
when craftbukkit starts up. The exception is files whose name begins
|

with an underscore `_` character. These files will not be

automatically loaded at startup as they are assumed to be files
|
||||
managed / loaded by plugins.

save() function
|
||||
---------------
|
||||
The save() function saves an in-memory javascript object to a
|
||||
specified file. Under the hood, save() uses JSON (specifically
|
||||
json2.js) to save the object. Again, there will usually be no need to
|
||||
call this function directly as all javascript plugins' state are saved
|
||||
automatically if they are declared using the `plugin()` function. Any
|
||||
in-memory object saved using the `save()` function can later be
|
||||
restored using the `load()` function.
|
||||
|
||||
Parameters
|
||||
----------
|
||||
|
||||
* objectToSave : The object you want to save.
|
||||
* filename : The name of the file you want to save it to.
|
||||
|
||||
Example
|
||||
-------
|
||||
|
||||
var myObject = { name: 'John Doe',
|
||||
aliases: ['John Ray', 'John Mee'],
|
||||
date_of_birth: '1982/01/31' };
|
||||
save(myObject, 'johndoe.json');

var __data = { "name": "John Doe",
|

"aliases": ["John Ray", "John Mee"],

"date_of_birth": "1982/01/31" };
|
||||
|
||||
plugin() function
|
||||
-----------------
|
||||
The `plugin()` function should be used to declare a javascript module
|
||||
whose state you want to have managed by ScriptCraft - that is - a
|
||||
Module whose state will be loaded at start up and saved at shut down.
|
||||
A plugin is just a regular javascript object whose state is managed by
|
||||
ScriptCraft. The only member of the plugin which whose persistence is
|
||||
managed by Scriptcraft is `state` - this special member will be
|
||||
automatically saved at shutdown and loaded at startup by
|
||||
ScriptCraft. This makes it easier to write plugins which need to
|
||||
persist data.
|
||||
|
||||
Parameters
|
||||
----------
|
||||
|
||||
* pluginName (String) : The name of the plugin - this becomes a global variable.
|
||||
* pluginDefinition (Object) : The various functions and members of the plugin object.
|
||||
* isPersistent (boolean - optional) : Specifies whether or not the plugin/object state should be loaded and saved by ScriptCraft.
|
||||
|
||||
Example
|
||||
-------
|
||||
See chat/color.js for an example of a simple plugin - one which lets
|
||||
players choose a default chat color. See also [Anatomy of a
|
||||
ScriptCraft Plugin][anatomy].

|
||||
|
||||
command() function
|
||||
------------------
|
||||
The `command()` function is used to expose javascript functions for
|
||||
use by non-operators (regular players). Only operators should be
|
||||
allowed use raw javascript using the `/js ` command because it is too
|
||||
powerful for use by regular players and can be easily abused. However,
|
||||
the `/jsp ` command lets you (the operator / server administrator /
|
||||
plugin author) safely expose javascript functions for use by players.
|
||||
|
||||
Parameters
|
||||
----------
|
||||
|
||||
* commandName : The name to give your command - the command will be invoked like this by players `/jsp commandName`
|
||||
* commandFunction: The javascript function which will be invoked when the command is invoked by a player.
|
||||
* options (Array - optional) : An array of command options/parameters
|
||||
which the player can supply (It's useful to supply an array so that
|
||||
Tab-Completion works for the `/jsp ` commands.
|
||||
* intercepts (boolean - optional) : Indicates whether this command
|
||||
can intercept Tab-Completion of the `/jsp ` command - advanced
|
||||
usage - see alias/alias.js for example.
|
||||
|
||||
Example
|
||||
-------
|
||||
See chat/colors.js or alias/alias.js or homes/homes.js for examples of how to use the `command()` function.
|
||||
|
||||
ready() function
|
||||
----------------
|
||||
The `ready()` function provides a way for plugins to do additional
|
||||
setup once all of the other plugins/modules have loaded. For example,
|
||||
event listener registration can only be done after the
|
||||
events/events.js module has loaded. A plugin author could load the
|
||||
file explicilty like this...
|
||||
|
||||
load(__folder + "../events/events.js");
|
||||
|
||||
// event listener registration goes here
|
||||
|
||||
... or better still, just do event regristration using the `ready()`
|
||||
handler knowing that by the time the `ready()` callback is invoked,
|
||||
all of the scriptcraft modules have been loaded...
|
||||
|
||||
ready(function(){
|
||||
// event listener registration goes here
|
||||
// code that depends on other plugins/modules also goes here
|
||||
});
|
||||
|
||||
The execution of the function object passed to the `ready()` function
|
||||
is *deferred* until all of the plugins/modules have loaded. That way
|
||||
you are guaranteed that when the function is invoked, all of the
|
||||
plugins/modules have been loaded and evaluated and are ready to use.
|
||||
|
||||
Core Module - Special Variables
|
||||
===============================
|
||||
There are a couple of special javascript variables available in ScriptCraft...
|
||||
|
||||
* __folder - The current working directory - this variable is only to be used within the main body of a .js file.
|
||||
* _plugin - The ScriptCraft JavaPlugin object.
|
||||
* __plugin - The ScriptCraft JavaPlugin object.
|
||||
* server - The Minecraft Server object.
|
||||
* self - the current player.
|
||||
* self - the current player. (Note - this value should not be used in multi-threaded scripts - it's not thread-safe)
