摘要： 你将会学习一些与cocos2d配合使用的工具,比如Particle Designer。 没有这些工具,你只能成为“半个”cocos2d开发者。cocos2d 整合了两套物理引擎。一套叫 Chipmunk,另一套叫 Box2d。它们的功 能基本相同,最大的区别是编写它们所使用的编程语言:Chipmunk 是用 C 写的, Box2d 是用 C++写的。游戏开发者喜欢 cocos2d 的一个原因是它隐藏了底端的 OpenGL ES 代码。其他的一些 iOS 游戏引擎,比如 Unity, iTorque 和 Shiva 专注于提 供工具和流程以降低对编程知识的要求。你可以在此下载 cocos2d:h 阅读全文
