背景：
最近火爆全球的游戏flappy bird让笔者叹为观止，于是花了一天的时间山寨了一个一模一样的游戏，现在把游戏的思路和源码分享出来，代码是基于javascript语言，cocos2d-x游戏引擎，cocos2d-x editor手游开发工具完成的，请读者轻砸；
ps：运行demo必须配置好cocos2d-x editor，暂不支持其他工具。还有demo是跨平台的，可移植运行android，ios，html5移动系统等；
Android Apk下载：（演示效果）
暂时只移植打包到android系统，可下载运行看看效果；

开发工具：
cocos2dx editor，它是开发跨平台的手机游戏工具，运行window/mac系统上，javascript脚本语言，基于cocos2d-x跨平台游戏引擎, 集合代码编辑，场景设计，动画制作，字体设计，还有粒子，物理系统，地图等等的，而且调试方便，和实时模拟；

思路和源码：
1 场景设计MainLayer.ccbx，如下图；主要分三层，开始场景、主场景、游戏结束场景，通过显示隐藏控制三个场景的切换。
MainLayer.ccbx代码

2 代码编写MainLayer.js

后言：
为了鼓励更多手游爱好者加入cocos2d-x editor阵营，也为了读者坚定对该工具的信心，笔者基于以上的flappy bird代码和新的图片资源，往google play和中国应用市场发布了一个相似的游戏----腾飞的小鸟（fly bird）。该游戏还加入了广告模块，可以获得些许的广告费。也希望读者通过cocos2d-x editor可以在市场上发布更多的好游戏；
