as3访问孩子为正常影片剪辑（gotoAndPlay等）

Question

与as3仍然遇到障碍！这一次，我用addChild从我的库中创建了一个MC实例，现在需要访问这个孩子，就好像它是时间线上的一个正常MC，但无法使其工作。

如果我指的是它的实例名称，如：

this.getChildByName("mc1").gotoAndPlay(2); 

我得到的错误，它不能做到这一点的DisplayObject。

如果我指的是它通常就好像它是只是一个MC一样在时间轴上：

mc1.gotoAndPlay(2); 

话，就无法找到它（由于它是动态创建的，我认为

任何指导，将大大真的很感谢一如既往...

我可以弹出我的一些代码，如果你想一些背景。

非常感谢！

编辑：感谢您的答复 - 我不能得到这个工作，虽然？

var mc1:MovieClip = this.getChildByName("mc1") as MovieClip; 
if(mc1) { mc1.useHandCursor = true; 
mc1.buttonMode = true; 
mc1.addEventListener(MouseEvent.CLICK, fillDriveway); 

编辑：代码的要求：（什么，我想会是MC1一个例子的onclick到的gotoAndPlay）

你尝试将其转换为影片剪辑？

var mc:MovieClip = this.getChildByName("mc1") as MovieClip; 
if(mc) 
{ 
    mc.gotoAndPlay(); 
}
