Cocos2d-x3.5 设计Fly_bird(飞行的小鸟)并打包成APK文件

概述这个小的游戏代码可以使我们理解常见的cocos的概念，从场景，精灵，图层，到导演，回调函数，更新函数，再到设置物理世界，设置精灵刚体。不得不说cocos博大精深，不过有个大家一直在意的问题，就是cocos版本更新太快，有些东西不能使用或者使用错误。个人建议去看cocos官网的版本更新信息和去官网论坛提问或者加群讨论，这样更利于大家提高！ 上代码！代码大部分都有注释，如有问题可以提问！ 游戏由三个场

这个小的游戏代码可以使我们理解常见的cocos的概念，从场景，精灵，图层，到导演，回调函数，更新函数，再到设置物理世界，设置精灵刚体。不得不说cocos博大精深，不过有个大家一直在意的问题，就是cocos版本更新太快，有些东西不能使用或者使用错误。个人建议去看cocos官网的版本更新信息和去官网论坛提问或者加群讨论，这样更利于大家提高！上代码！代码大部分都有注释，如有问题可以提问！

游戏由三个场景构成，HelloWorldScene，GameScene，GameOver。

HelloWorldScene是初始场景
