动作脚本 3 - 等到影片剪辑动画完成，然后再执行下一行

Question

假设我有这个AS3代码：

playButtonContainer.addEventListener(MouseEvent.CLICK, playButtonClicked);
function playButtonClicked(evt:MouseEvent) {
    instructionsContainer.gotoAndPlay(2);
    analysisScreenContainer.gotoAndPlay(2);
    playButtonContainer.gotoAndPlay(2); 
    statusDescriptionContainer.gotoAndPlay(2);
}

在instructionsContainer、analysisScreenCnotainer、playButtonContainer和statusDescriptionContainer里面是一个电影剪辑，它有自己的时间轴和动画。

如您所见，我有 4 个不同的影片剪辑一个接一个地播放。我该如何使它

statusDescriptionContainer.gotoAndPlay(2);

仅在动画之后执行

playButtonContainer.gotoAndPlay(2); 

完成执行和

playButtonContainer.gotoAndPlay(2); 

仅在

playButtonContainer.gotoAndPlay(2); 

动画完成？

切尔尼夫建议你什么，或者你可以添加一个事件侦听器，只听输入帧。在那里，您只需检查当前帧是否等于总帧数。或者，您可以扩展影片剪辑：

package {
    import flash.display.MovieClip;
    import flash.events.Event;
    public class AdvancedMovieClip extends MovieClip {
        public function AdvancedMovieClip() {
            this.addEventListener(Event.ENTER_FRAME, onEnterFrame);
        }
        private function onEnterFrame(e:Event):void {
            if(this.currentFrame == this.totalFrames) {
                dispatchEvent(new Event(Event.COMPLETE));
            }
        }
        public function destroy():void {
            this.stop();
            this.removeEventListener(Event.ENTER_FRAME, onEnterFrame);
        }
    }
}

你可以尝试这样的事情：

playButtonContainer.addEventListener(MouseEvent.CLICK, playButtonClickedHandler, false, 0, true);
function playButtonClickedHandler(event:MouseEvent):void
{
    trace('instructionsContainer');
    instructionsContainer.addFrameScript(instructionsContainer.totalFrames -1, playStatusDescriptor);
    instructionsContainer.gotoAndPlay(2);
}
function playStatusDescriptor():void
{
    instructionsContainer.stop();
    trace('statusDescriptionContainer');
    statusDescriptionContainer.addFrameScript(statusDescriptionContainer.totalFrames -1, playAnalysisScreen);
    statusDescriptionContainer.gotoAndPlay(2);
}
function playAnalysisScreen():void
{
    statusDescriptionContainer.stop();
    trace('playAnalysisScreen');
    analysisScreenContainer.addFrameScript(analysisScreenContainer.totalFrames -1, playAnotherButton);
    analysisScreenContainer.gotoAndPlay(2);
}
function playAnotherButton():void
{
    analysisScreenContainer.stop();
    trace('playAnotherButton');
    anotherScreenContainer.addFrameScript(anotherScreenContainer.totalFrames -1, somethingElse);
    anotherScreenContainer.gotoAndPlay(2);
}
function somethingElse():void
{
    anotherScreenContainer.stop();
    trace('somethingElse');
}
