我有一个两帧 Flash CS3 动画。在第一帧上，我（成功地）将四个图像加载到帧上，并使用 TweenLite （成功地）旋转它们。当用户点击一个按钮时，会设置一个变量（resumeVideoOn）来指示用户正在查看的当前图像，并将它们带到播放相应视频的frame2。视频播放完毕后，用户可以选择单击按钮重播视频，或单击按钮将视频带回到 frame1（通过简单的 gotoAndPlay(1) 调用）。当用户返回到 frame1 时，我检测“resumeVideoOn”的值以确定要恢复动画循环的函数。它正确加载初始图像。然而，虽然它继续运行一系列函数（由于跟踪以及在这些函数中调用的其他补间正常工作这一事实，我可以看出），但仅显示您返回的原始图像（其他三个图像被调用TweenLite 不出现）。我已经在这个圈子里转了一段时间了。下面是一些代码，虽然有很多，所以我试着只放必要的东西：

// pull in images and video properties thru XML
var myXMLLoader:URLLoader = new URLLoader();
myXMLLoader.load(new URLRequest("flash.xml"));
myXMLLoader.addEventListener(Event.COMPLETE, processXML);

function processXML(e:Event):void {
    var myXML:XML = new XML(e.target.data);
    my_videos = myXML.VIDEO;
    my_total = my_videos.length();
    if(my_total > 0) {
        makeContainers();
        callImgs();
    } else {
        trace("put alternate case here in case nothing is loaded");        
    }
}

function makeContainers():void {
    main_container = new Sprite();
    addChild(main_container);

    main_container.addChild(image1);
    main_container.addChild(image2);
    main_container.addChild(image3);
    main_container.addChild(image4);

    setChildIndex(DisplayObjectContainer(main_container),0);
}

function callImgs():void {
    var img_loader1 = new Loader();
    img_loader1.load(new URLRequest(my_videos[0].@IMG));
    image1.addChild(img_loader1);
    wtv1 = my_videos[0].@WTVPOS;
    video1 = my_videos[0].@VIDURL;

    var img_loader2 = new Loader();
    img_loader2.load(new URLRequest(my_videos[1].@IMG));
    image2.addChild(img_loader2);
    wtv2 = my_videos[1].@WTVPOS;
    video2 = my_videos[1].@VIDURL;

    var img_loader3 = new Loader();
    img_loader3.load(new URLRequest(my_videos[2].@IMG));
    image3.addChild(img_loader3);
    video3 = my_videos[2].@VIDURL;
    wtv3 = my_videos[2].@WTVPOS;

    var img_loader4 = new Loader();
    img_loader4.load(new URLRequest(my_videos[3].@IMG));
    image4.addChild(img_loader4);
    wtv4 = my_videos[3].@WTVPOS;
    video4 = my_videos[3].@VIDURL;
}

function imgLoaded(e:Event):void {
    var my_img:Loader = Loader(e.target.loader);
    image1.addChild(my_img);
}


//tween and go to video on frame 2 if clicked on myFrame1()
function myFrame1():void {
    //image 1
    image1.alpha = 100;// start faded down

    TweenLite.to(selectedFrame, 1, {x:501.6, overwrite:1});
    TweenLite.to(image1, 1, {alpha:0, delay:3, overwrite:0});
    TweenLite.to(image2, 1, {alpha:1, delay:3, overwrite:0});
    //wtv1
    if(wtv1 == "right") {
        TweenLite.to(watchthevideo_right_mc, 1, {alpha:1});
        watchthevideo_right_mc.addEventListener(MouseEvent.CLICK, playVideo1);
        TweenLite.to(watchthevideo_right_mc, 1, {alpha:0, delay:3, overwrite:0, onComplete:myFrame2});
    } else {
        TweenLite.to(watchthevideo_left_mc, 1, {alpha:1});
        watchthevideo_left_mc.addEventListener(MouseEvent.CLICK, playVideo1);
        TweenLite.to(watchthevideo_left_mc, 1, {alpha:0, delay:3, overwrite:0, onComplete:myFrame2});
    }
}

function playVideo1(e:MouseEvent):void {
    //kill all tweens
    TweenLite.killTweensOf(watchthevideo_right_mc);
    TweenLite.killTweensOf(watchthevideo_left_mc);
    TweenLite.killTweensOf(image1);
    TweenLite.killTweensOf(image2);
    TweenLite.killTweensOf(image3);
    TweenLite.killTweensOf(image4);
    videoFile = video1;
    resumeVideoOn = 1;
    gotoAndPlay(2);
}

// on frame 2
// after video is played
function returnShow(e:MouseEvent):void {
    TweenLite.to(_replayButton, 1, {alpha:0, overwrite:0});
    TweenLite.to(_returnButton, 1, {alpha:0, overwrite:0});
    _replayButton.visible = false;
    _returnButton.visible = false;
    TweenLite.to(rectangle, 1, {alpha:0, overwrite:0});

    //reset all video data
    removeChild(video);
    removeChild(pause_mc);
    removeChild(play_mc);
    removeChild(volslide_mc);
    removeChild(controls_mc);
    removeChild(controlBacker_mc);
    removeChild(_replayButton);
    removeChild(_returnButton);

    gotoAndPlay(1);
}

// when the user returns to frame 1, the variable 'resumeVideoOn' is checked 
// in an if statement to determine where to resume.  the if statement is run, 
// then goes to function myFrame2 (or whatever the next frame is), but the image
// is not changing

另外，我的 xml 文件如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<MYLIST>
<VIDEO VIDURL="videos/video1.flv" WTVPOS="right" IMG="imgs/image1.jpg" />
<VIDEO VIDURL="videos/video2.flv" WTVPOS="left" IMG="imgs/image2.jpg" />
<VIDEO VIDURL="videos/video3.flv" WTVPOS="right" IMG="imgs/image3.jpg" />
<VIDEO VIDURL="videos/video4.flv" WTVPOS="left" IMG="imgs/image4.jpg" />
</PHHLIST>

只是想通了，对于任何关心的人......我需要添加一个

removeChild(main_container);

到将用户发送到第 2 帧的函数。当我将显示窗口拖到比视频窗口大时，我可以看到原始图像仍在舞台上，因此当用户返回第 1 帧时阻止了任何图像的显示。
