It uses LWJGL ( for rendering, instead of Java's built-in Swing/AWT components.

Building and running

The following steps are required to build and run the jar. (An Eclipse project has been included for convenience, but the project config may need to be adjusted to suit your environment.)

  1. Build the jar: $ ant

    (ant is of course required)

  2. Run the jar:

    $ java -jar GameDemo.jar
