Libgdx is a cross-platform Java game development framework based on OpenGL (ES) that works on Windows, Linux, Mac OS X, Android, your WebGL enabled browser and soon iOS.

This project has a few prerequisites but primarily uses the ant build tool. If you wish to compile the code then just check it out and:

cd /path/to/libgdx
ant

And it should compile.

There are a number of example games in the source. Some of them include:

• metagun
• superjumper
• gdx-vertorpinball
• rtm
• very angry robots

To see how to use libgdx you can either go to the wiki (which has plenty of good information) or read through these example projects. Once again, if you get stuck just drop in to the friendly forums.
