在实际项目中实现把swf资源里面的MC进行转化成按钮，实现代码的复用
下面是前不久一个游戏项目中的一小部分内容，拿出来只是为了说明，用AS3对加载进程序中swf内容进行封装变换处理
下面是这个例子，只不过不完整。。。

从上面可以看到GameLoader类是加载整个的SWF文件（这里是一个公会转盘的SWF文件），集体的加载过程是在ResFuns类的getRes()方法中，这是一个封装很好的项目，学到了很多东西。。
看到这一句了吗？？ this._buyEBtn = new EButton(); this._buyEBtn.changeBtn(this._panel.signBtn);这里是使用了EButton类里面的一个方法changeBtn把this._panel.signBtn这个MC转化为了按钮，使这个MC具有了按钮的所有功能（主要还是监听事件，实现鼠标over和out的效果等），这样EButton类可以实现把任何4帧的MC转化成按钮，提高了代码的复用。。
下面就是EButton这个类：

以上就是怎样在实际的项目开发中把4帧的MC转化成一个按钮，通过这种形式来实现代码的复用。。。
