Today we have another native iPhone Open Source library in development for you:
cocos2d-iphone is a framework for building 2D games, demos, and other graphical/interactive applications. It is based on the cocos2d design: it uses the same API, but instead of using python it uses objective-c.
A cocos2d-iphone application consists of several scenes, and a workflow connecting the different scenes. It provides you with a “director” which handles the workflow between scenes. Each scene is composed of an arbitrary number of layers; layers take care of drawing to the screen (using the OpenGL ES APIs), handling events and in general contain all of the game/application logic.
cocos2d-iphone simplifies the game development in these areas:
- Defining a workflow for your game
- Creating special effects in layers
- Creating transitions between scenes
- Managing sprites
- Basic menus
- Integrated Chipmunk 2d physics engine
- Particle system
- Text rendering support
- Touch/Accelerometer support
- Integrated Pause/Resume
- Language: objective-c
