在影片剪辑访问影片剪辑 [英] Accessing Movieclips in movieclips

问题描述

我开始用AS3编程ICM使用Flash Builder 4。

I am starting with AS3 programming icm with Flash Builder 4.

我创建了一个主类，它是初始阶段。

I have created a "Main" class which is the initial stage.

在这个阶段有一个叫做mcMain影片剪辑。

On this stage there is a movieclip called mcMain.

在此mcMain是4其他影片剪辑：mcStats1 mcStats2 mcStats3 mcStats4

In this mcMain is 4 other movieclips: mcStats1 mcStats2 mcStats3 mcStats4

我怎样才能从code访问这些mcStats1-4让他们去另一帧？

How can I access these mcStats1-4 from the code to make them go to another frame?

我想：

var t:MovieClip = MovieClip(getChildByName("mcMain"));
t.getChildByName("mcStats1").gotoAndPlay(3);

但是，这只是不断给我空引用错误： 类型错误：错误＃1009：无法访问空对象引用的属性或方法

But that just keeps giving me null reference errors: TypeError: Error #1009: Cannot access a property or method of a null object reference.

所以，我应该怎么解决这个问题？

So how should I solve this?

推荐答案

我想它了自己，这并不容易，但apperantly类型转换是在AS3的答案。

I figured it out myself, it wasn't easy but apperantly typecasting is the answer in AS3.

var p1:mcUserStats; //class name
p1 = ((this.mcMain as MovieClip).mcStats1 as mcUserStats);
