OtherBlocks is a plugin for the Minecraft Bukkit API that lets you completely customize what blocks and dead mobs drop when they are destroyed. Apples from leaves, no more broken glass, you name it!
The related discussion thread for this plugin is located at http://forums.bukkit.org/threads/4072/.
Please see the project wiki for details on how to set up OtherBlocks.
OtherBlocks relies on submodules, so after cloning the project:
$ git submodule update --init
Then stick a Bukkit build in lib, following the bukkit-version-build.jar
naming convention:
$ wget -O lib/bukkit-0.0.1-r746.jar http://ci.bukkit.org/job/dev-Bukkit/promotion/latest/Recommended/artifact/target/bukkit-0.0.1-SNAPSHOT.jar
$ ant build
Ant will automatically pick out the latest Bukkit build in lib. To manually
specify a Bukkit version to build against, set the lib.bukkit.version
property on the command line:
$ ant -Dlib.bukkit.version="0.0.1-r746" build
Use ant -p to see a complete list of Ant tasks.
