I created ScriptCraft to make it easier for younger programmers to
|
|
create their own Minecraft Mods. Mods are written using the
|
|
Javascript programming language. Once the ScriptCraft mod is
|
|
installed, you can add your own new Mods by adding Javascript (.js)
|
|
files in a directory.
|
|
|
|
* If you're new to programming and want to start modding Minecraft, then [Start Here][ypgpm].
|
|
* If you've already used [Scratch][scr], have attended a few
|
|
[CoderDojo][cd] sessions, or have already dabbled with Javascript,
|
|
then [Start Here][cda].
|
|
* Watch some [demos][ytpl] of what you can do with ScriptCraft.
|
|
|
|
This is a simple mod in a file called greet.js in the scriptcraft/plugins directory...
|
|
|
|
```javascript
|
|
exports.greet = function( player ) {
|
|
echo( player, 'Hello ' + player.name );
|
|
};
|
|
```
|
|
|
|
At the in-game prompt, type...
|
|
|
|
/js greet(self)
|
|
|
|
... to see the greeting. Anything you can do using CanaryMod or CraftBukkit's API in Java, you can do using ScriptCraft in Javascript.

# Description
|
|
|
|
ScriptCraft is a plugin for Minecraft Servers which lets operators,
|
|
administrators and plug-in authors customize the game using
|
|
Javascript. ScriptCraft makes it easier to create your own mods. Mods
|
|
can be written in Javscript and can use the full [CanaryMod API][cm]
|
|
or [Bukkit API][bukkit]. I recommend using CanaryMod because
|
|
CraftBukkit is no longer being actively developed due to a legal
|
|
dispute. The ScriptCraft mod also lets you enter javascript commands
|
|
at the in-game prompt. To bring up the in-game prompt press the `/`
|
|
key then type `js ` followed by any javascript statement.
|
|
For example: `/js 1 + 1` will print 2.
|
|
|
|
ScriptCraft also includes many objects and functions to make building
|
|
and modding easier using Javascript. The Javascript `Drone` object
|
|
bundled with ScriptCraft provides an easy way to build at-scale in
|
|
Minecraft. See the attached [temple.js][temple] file for an example
|
|
of how you can use the sample Drone plugin to create new buildings in
|
|
Minecraft.

# Prerequisites
|
|
|
|
You will need to have Java version 6 or later installed on your
|
|
machine. Check the version by typing `java -version` at a command
|
|
prompt. You will need to [install CanaryMod][ic] or [install Bukkit][ib]
|
|
on your machine (I recommend using CanaryMod as Bukkit is
|
|
no longer being actively developed). CanaryMod and Bukkit are both
|
|
versions of Minecraft (server) that make it easy to install plugins
|
|
and customize Minecraft. You can [download the CanaryMod server
|
|
here.][ic]
|
|
|
|
# Installation
|
|
|
|
If you don't want to compile from source, you can [download the
|
|
compiled plugin here][dl] and copy it the craftbukkit's plugins
|
|
directory.
|
|
|
|
# Post Install
|
|
|
|
Once installed, a new scriptcraft/plugins directory is automatically created. All files in the scriptcraft/plugins
|
|
directory will be automatically loaded when the server starts. *Only
|
|
players who are ops can use this plugin.* You can grant a player `op`
|
|
privileges by typing 'op <username>' at the server console prompt or
|
|
by adding the player's username to the ops.txt file in your
|
|
server directory.
|
|
|
|
Launch the server, then launch the Minecraft client and create a new
|
|
server connection. The IP address will be `localhost` . Once you've
|
|
connected to your server and have entered the game, look at a
|
|
ground-level block and type ...
|
|
|
|
/js up().box( blocks.wool.black, 4, 9, 1 )
|
|
|
|
... This will create a black monolith structure 4 blocks wide by 9
|
|
blocks high by 1 block long. Take a look at the
|
|
src/main/javascript/drone/drone.js file to see what ScriptCraft's
|
|
drone can do. If you're interested in customizing minecraft beyond
|
|
just creating new buildings, take a look at [./homes/homes.js][homes] for examples of how to create a
|
|
javascript plugin for Minecraft.

|
|
[si]: blob/master/src/main/javascript/modules/signs/menu.js
|
|
|
|
A Javascript mod for minecraft is just a javascript source file (.js)
|
|
located in the craftbukkit/plugins/scriptcraft/plugins directory. All .js files in this
|
|
directory will be automatically loaded when the craftbukkit server
|
|
starts. To get started writing your own mod, first take a look at some
|
|
of the existing mods in the [homes][ho], [arrows][ar] and
|
|
[signs][si] directories.
|
|
|
|
# Additional information
|
|
|
|
Because the CanaryMod API is open, all of the CanaryMod API is accessible
|
|
via javascript once the ScriptCraft plugin is loaded. There are a
|
|
couple of useful Java objects exposed via javascript in the
|
|
ScriptCraft plugin...
|
|
|
|
* `__plugin` - the ScriptCraft Plugin itself. This is a useful
|
|
starting point for accessing other CanaryMod objects. The `__plugin`
|
|
object is of type [net.canarymod.plugin.Plugin][api] and all
|
|
of its properties and methods are accessible. For example... `js
|
|
__plugin.name` returns the plugin's name
|
|
(javascript is more concise than the equivalent java code:
|
|
__plugin.getName() ).
|
|
|
|
* `server` - The top-level net.canarymod.Server object. See the [CanaryMod API docs][cmapi] for reference.
|
|
|
|
* `self` - The player/command-block or server console operator who
|
|
invoked the `/js` command. Again, this is a good jumping off point for
|
|
diving into the CanaryMod API.

# Bukkit Configuration (You can ignore this if usng CanaryMod)
|
|
|
|
ScriptCraft also works with Bukkit Plugin and uses the Bukkit Configuration
|
|
API. On first loading, ScriptCraft will create a config.yml file in
|
|
the plugins/scriptcraft/ directory. This file looks like this...
|
|
|
|
extract-js:
|
|
plugins: true
|
|
modules: true
|
|
lib: true
|
|
|
|
This file allows scriptcraft admins to turn on or off re-unzipping of the `modules`,
|
|
`plugins` and `lib` folders when deploying a new version of
|
|
scriptcraft. It's strongly recommended that the `lib` directory always
|
|
be set to true to get the latest core scriptcraft code . The modules
|
|
and plugins directories are optional and not part of scriptcraft core.
