Impact++
Impact++ is a pretty incredible set of extensions for the Impact.js HTML5 Game engine that adds in:
- Realtime Dynamic Lighting
- Shadows
- Pixel Perfect Lighting
- Performance enhanced Box2D intergration with collision map slope support
- Base Entity and Character classes
Written by Colin Hover, the extension adds a whole lot of goodies to an already excellent engine.
The extension is a very young project and be careful with performance, but the demo is impressive.
