AS3时间轴变量问题 [英] AS3 Timeline Variable issues

问题描述

我想从时间线动态影片剪辑。

I'm trying to get a dynamic movie clip from the timeline.

我有未知长度的影片剪辑实例名称嗒嗒的时间轴上的关键帧（假设在这种情况下，88）之一。
无论我做什么，我不能让一个参照上述影片剪辑。

I have a timeline of unknown length with a movie clip with instance name "blah" on one of the key frames (assumed 88 in this case).
No matter what I do, I cannot get a reference to the said movie clip.

下面是我的尝试：

trace(blah); // null
trace(this.blah); // null
trace(getChildByName("blah")); // null

if(currentFrame == 88)
    trace(getChildByName("blah")); // null

for(var i:int=0; i<numChildren; ++i)
    trace(getChildAt(i));
/* Returns:
 * [object MovieClip]
 * [object Shape]
 * null
 * [object TextField]
 */

// Assuming the first movie clip is the correct one
trace(getChildAt(0).name); // instance?? where ?? are random digits, I'm expecting "blah"

是否有人可以揭示如何通过code导入时间表生成的对象？

Can someone please shed light on how to import timeline generated objects through code?

推荐答案

如果你才刚刚导航到框架88这可能是因为你试图使用它之前，它已经初始化。试着增加：

If you have only just navigated to frame 88 it could be that you are trying to use it before it has initialised. Try adding:

stage.addEventListener(Event.ADDED, onAdded);

function onAdded(event:Event):void
{
    trace("new object "+event.target);
    trace("new object name "+event.target.name);
}
