Projects / JGame


JGame is a 2D game engine that makes multi-platform development easier. It runs on the Java JRE 1.3+ platform with optional OpenGL (JOGL) enhancements, the J2ME (MIDP2.0/CLDC1.1) mobile platform, and the Android (2.1+) platform. JGame features sprites with automatic animation and collision detection, a tile-based background with easy sprite-tile interaction facilities, automatic scaling, sound, game state, persistent storage, and game options. The engine provides an enhanced graphics API with a fallback to simpler and more efficient graphics on J2ME and plain JRE. A patched version of the JBox2D physics engine that runs on all platforms is included.
