Pixelizer is an entity and component based game framework. Since it is based on entities and components, it’s is very easy to extend and reuse.

Features:

• easy extendable component based framework
• nestable entities for easy manipulation of groups
• lots of premade components and entities
• fast 2D rendering
• automated collision detection and response
• spritesheets, animations and tilemaps
• prerendering of movieclips
• automatic panning and volume of moving sounds
• exact mouse and keyboard input
• fancy text rendering
• handy math and string routines
• effective object pools
• useful logging
• and much more
