Flash AS3 Tweelite 和 XML 问题

Question

我有一个两帧 Flash CS3 动画。在第一帧上，我（成功）将四个图像加载到帧上，并使用 TweenLite（成功）旋转它们。当用户单击按钮时，将设置一个变量 (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第 2 帧。视频播放完毕后，用户可以选择单击按钮重播视频，或单击按钮返回第 1 帧（通过简单的 gotoAndPlay(1) 调用）。当用户返回到第 1 帧时，我检测“resumeVideoOn”的值来确定恢复动画循环的函数。它正确加载初始图像。然而，当它继续运行一系列函数时（我可以通过痕迹以及在这些函数中调用的其他补间正常工作的事实来判断），只有您返回的原始图像正在显示（其他三个图像是由 TweenLite 调用的不会出现）。我已经在这个问题上兜圈子了一段时间了。下面是一些代码，虽然有很多，所以我尝试只放置必要的东西：

// 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>

Answer 1

刚刚弄清楚，对于任何关心的人...
我需要

removeChild(main_container);

在将用户发送到第 2 帧的函数中添加 a 。当我将显示窗口拖动到大于视频窗口时，我可以看到原始图像仍然在舞台上，从而阻止了用户返回时显示的任何图像到第 1 帧。
