flash - 如何在 Flash CS5 中制作通用暂停按钮？

Question

我正在尝试在 Flash 中制作一个按钮，暂停在我的文件中运行的所有影片剪辑。这些影片剪辑都不是我的主时间线中的补间，它们都有自己的时间线。每个移动剪辑都由一个按钮触发，该按钮告诉剪辑开始播放。所以，如果有人能帮我创建这个暂停按钮，我将不胜感激。感谢您的时间。

使用像这样的基类递归地导出要暂停/恢复的所有符号，然后您不必遍历整个显示树:

package com.stackoverflow
{
import flash.display.MovieClip;
import flash.events.Event;

[Event(name="clipAdded", type="flash.events.Event")]
[Event(name="clipRemoved", type="flash.events.Event")]
public class BaseClip extends MovieClip
{
    protected var baseClipChildren:Array;
    protected var paused:Boolean = true;

    public function BaseClip()
    {
        super();
        baseClipChildren = new Array();
        addEventListener(Event.ADDED_TO_STAGE, onAdded);
        addEventListener("clipAdded", onClipAdded);
        addEventListener(Event.REMOVED_FROM_STAGE, onRemoved);
        addEventListener("clipRemoved", onClipRemoved);
    }

    protected function onAdded(event:Event):void
    {
        var target:BaseClip = event.target as BaseClip;
        if(target == this) {
            dispatchEvent(new Event("clipAdded", true));
        }
    }

    protected function onClipAdded(event:Event):void
    {
        var target:BaseClip = event.target as BaseClip;
        if(target && target != this) {
            event.stopImmediatePropagation();
            baseClipChildren.push(target);
        }
    }

    protected function onRemoved(event:Event):void
    {
        var target:BaseClip = event.target as BaseClip;
        if(target == this) {
            dispatchEvent(new Event("clipRemoved", true));
        }
    }

    protected function onClipRemoved(event:Event):void
    {
        var target:BaseClip = event.target as BaseClip;
        if(target && target != this) {
            event.stopImmediatePropagation();
            baseClipChildren.splice(baseClipChildren.indexOf(target),1);
        }
    }

    public function stopAll():void {
        stop();
        for each(var clip:BaseClip in baseClipChildren) {
            clip.stopAll();
        }
    }

    public function playAll():void {
        play();
        for each(var clip:BaseClip in baseClipChildren) {
            clip.playAll();
        }
    }
}
}
