Hungry Hero is an open source Flash game developed with the Starling Framework, designed as an educational example for developers interested in Stage3D and GPU-accelerated game development. The game demonstrates how to leverage Starling’s features to create smooth, hardware-accelerated 2D experiences while maintaining cross-device compatibility through Adobe AIR and Flash. It showcases core concepts such as handling textures, sprite sheets, parallax backgrounds, and collision detection, providing a clear reference for building interactive games. The project also integrates advanced techniques like object pooling for performance, bitmap fonts for efficient text rendering, and Starling’s particle system extension for visual effects. Though originally built with the iPad 1 and 2 in mind, it can be adapted to multiple devices by adjusting configuration files, emphasizing the principle of “one code, multi-screen.”

Nameless Engine is an open source game framework for ActionScript/Flex which component-based architecture provides maximum flexibility and extensibility, delivering a rapid development pipeline that can be used in many different games.
