WorldEdit
|
||||
=========
|
||||
|
||||
WorldEdit is a voxel and block manipulation library for Minecraft. It is
|
||||
primarily a library but bindings to Bukkit (included) and SPC (external)
|
||||
are available.
|
||||
|
||||
Compiling
|
||||
---------
|
||||
|
||||
Some dependencies are required:
|
||||
|
||||
- TrueZip (http://java.net/projects/truezip) provides snapshot reading
|
||||
- Bukkit (http://bukkit.org/) is a SMP plugin API
|
||||
- Rhino (http://www.mozilla.org/rhino/) provides a JavaScript engine
|
||||
- GroupUsers (http://forums.bukkit.org/threads/639/) provides an
|
||||
permission system for Bukkit
|
||||
- Permissions (http://forums.bukkit.org/threads/1403/) provides an
|
||||
permission system for Bukkit
|
||||
|
||||

|
||||
http://wiki.sk89q.com/wiki/WorldEdit/Development
|
||||
|
||||
To compile a .jar, use the Ant build file with the 'jar' target.
|
||||
|
||||
ant jar
|
||||
|
||||
Contributing
|
||||
------------
|
||||
|
||||
We happily accept contributions. The best way to do this is to fork
|
||||
WorldEdit on GitHub, add your changes, and then submit a pull request. We'll
|
||||
look at it, make comments, and merge it into WorldEdit if everything
|
||||
works out.
