cocos2d for iPhone

cocos2d for iPhone is a framework for building 2D games, demos, and other graphical/interactive applications for iPod Touch, iPhone, iPad and Mac. It is based on the cocos2d design but instead of using python it, uses objective-c.

Main features

• Scene management (workflow)
• Transitions between scenes
• Sprites and Sprite Sheets
• Effects: Lens, Ripple, Waves, Liquid, etc.
• Actions (behaviours):
  • Trasformation Actions: Move, Rotate, Scale, Fade, Tint, etc.
  • Composable actions: Sequence, Spawn, Repeat, Reverse
  • Ease Actions: Exp, Sin, Cubic, Elastic, etc.
  • Misc actions: CallFunc, OrbitCamera, Follow, Tween
• Basic menus and buttons
• Integrated with physics engines: Box2d and Chipmunk
• Particle system
• Fonts:
  • Fast font rendering using Fixed and Variable width fonts
  • Support for .ttf fonts
• Texture Atlas support
• Tile Map support: Orthogonal, Isometric and Hexagonal
• Parallax scrolling
• Motion Streak
• Render To Texture
• High Score server (cocosLive library)
• Touch/Accelerometer on iOS
• Touch/Mouse/Keyboard on Mac
• Portrait and Landscape mode on iOS
• Sound Engine support (CocosDenshion library) based on OpenAL
• Integrated Pause/Resume
• Integrated Slow motion/Fast forward
• Fast textures: PVR compressed and uncompressed textures
• Point based: iPhone4 + RetinaDisplay mode compatible
• Language: objective-c
• Open Source: Compatible with open and closed source projects
• OpenGL ES 1.1 (iOS) / OpenGL 1.5 based (Mac)

This library does not work with the toolchain, but it should be easy to port it to it.

How to run the tests

Xcode -> View -> Customize toolbar
Then, drag "Active Target" and "Active Executable" to your top project tool bar. Select the test you want to view in both drop downs and hit Build and Go.

How to start a new game

Run the install-templates.sh script:

$ cd cocos2d-iphone
$ ./install-templates.sh -u -f

And then open XCode -> New Project -> User Templates -> cocos2d
