我成功加载单个图像并使用 addChild() 创建它。现在我正在尝试使用 forEach 循环将多个图像加载到一个精灵“容器”中,增加每个图像的 X 值,以便它们连续显示。图像加载器被引用到 XML 文档中的链接。如果我测试运行此代码,则在加载图像时会弹出此错误,并且我尝试 removeChild() loadBar 动画。
ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.

这是AS3:
private function loadBG():void {
var artGrab:Number = 0;
var artX:Number = 0;
for each (var albumData:XML in mainXML.artist[artistID].album) {
imgURL = new URLRequest(mainXML.artist[artistID].album[artGrab].art);
imgLdr = new Loader();
//if you're loading a bigger image or need a preloader
imgLdr.contentLoaderInfo.addEventListener(Event.COMPLETE,onBGLoaded);
imgLdr.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, onLoading);
//add loader animation "All Loader"
ldrAnim = new AllLoader();
albumContainer.addChild(ldrAnim);
ldrAnim.x = artX;
ldrAnim.y = 200;
imgLdr.load(imgURL);
artGrab++;
artX + 481;
ldrAnim.x + 481;
}
}
private function onLoading(evt:ProgressEvent):void {
var bytesToLoad:Number = imgLdr.contentLoaderInfo.bytesTotal;
var numberLoaded:Number = imgLdr.contentLoaderInfo.bytesLoaded;
ldrAnim.progBar.scaleX = numberLoaded / bytesToLoad;
var loadedPercent = Math.round(numberLoaded / bytesToLoad * 100);
ldrAnim.progPercent.text = loadedPercent + " %";
trace("Loading..." + loadedPercent + "%");
}
private function onBGLoaded(evt:Event):void {
trace("image loaded!");
//image setup
addChildAt(imgLdr,0);
//now that its 100% loaded, you can resize it , etc.
removeChild(ldrAnim);
//use cross multiplying of fractions to maintain aspect ratio
var origW = imgLdr.contentLoaderInfo.width;
var origH = imgLdr.contentLoaderInfo.height;
trace("orig width: "+ origW + "orig height: " + origH);
//set new width
imgLdr.width = 481;
var newH:Number = 481 * origH / origW;
imgLdr.height = newH;
//may wish to do positioning AFTER resizing
imgLdr.x = stage.stageWidth / 2 - imgLdr.width / 2;
imgLdr.x = 0;
imgLdr.y = 0;
imgLdr.width = 480;
imgLdr.height = 480;
imgLdr.alpha = 1;
imgLdr.z = 0;
}
祝福您阅读了这一切,我不明白是什么导致了这个错误,所以感谢您的评论!
