Tank Battles is a 3D simulator for teaching robot artificial inteligence. It's
heavilly influenced by Robocode, but differs from the former in that it adds the complexity of a full 3D scene, realistic physicssimulation, among other features.
A software library to bridge Simpull, a 2D Java Physics Engine, and PulpCore, a 2D rendering and animation framework. This will expand the capabilities of PulpCore to include physics simulations. Just extend SimpullScene2D and have at it!
