Actionscript 3 在Actionscript中使用数组加载多个图像

我有一个课堂作业，我必须创建一个照片库，其中一个规定是图像需要从外部来源加载。我们任务中的参考代码为：

var myRequest:URLRequest = new URLRequest("bw1.jpg");
myLoader.load(myRequest); 
addChild(myLoader); 

我的特殊需求要求我一次在屏幕上最多有两份图像，一份作为缩略图，另一份作为全尺寸图像。我希望这样，当用户单击缩略图时，会创建一个新的图片实例，并以0 alpha缩放到全尺寸，当前选定的图片的alpha值会随着新图片的alpha值增加而减少。一旦旧照片不再可见，它将从舞台上移除

我很难弄清楚如何在actionscript中创建映像的副本，而且我的for循环似乎没有正确执行，因为即使没有错误消息，它也只经过一次迭代

这里有一个通过pastebin链接到我的代码的链接：但为了避免您在这两者之间来回切换，我也将在这里跳过它

import flash.display.Bitmap;

//creates a loader for each picture to be loaded, I know I could have an empty array  
that I add to but created a full array to test.

var loaders:Array = [new Loader(),new Loader(), new Loader(), new Loader(), new
Loader(), new Loader(), new Loader(), new Loader(), new Loader(), new Loader()];
 //stores the url request for each image to be loaded

var Requests:Array =[new URLRequest("pic1.jpg"),new URLRequest("pic2.jpg"),new 
URLRequest("pic3.jpg"),
new URLRequest("pic4.jpg"),new URLRequest("pic5.jpg"),new URLRequest("pic6.jpg"), new  
URLRequest("pic7.jpg"),
new URLRequest("pic8.jpg"), new URLRequest("pic9.jpg"),new URLRequest("pic10.jpg")];



//creates 2 empty arrays one to store the thumbnail sized pics the other fullsized.    
Ideally I want one Array holding the bitmap data and the other holding the thumbnail 
 instances since I only need 2
// fullsized images at a time I can just create a new one and erase the old one in a 
single function.

var pics:Array = new Array();
var pics2:Array = new Array();

//defines an empty bitMap variable as a placeholder for which to copy from redefined in
 every iteration of the loop

var test:Bitmap;

//loops through every loader
for (var i in loaders);
{
        // loads the loader and url request and creates a picture
        loaders[i].load(Requests[i]);

        //waits for the pic to load 
        loaders[i].contentLoaderInfo.addEventListener(Event.COMPLETE, loadComplete);

        //after loader is loaded create pic from the data
        function loadComplete(evt:Event):void
       {
            var i = "Test";
            trace(i);
            test= evt.target.content as Bitmap;
            pics2[i] = test;
            pics[i] =new Bitmap(test.bitmapData);
            pics2[i] =new Bitmap(test.bitmapData);

    //creates an image on the stage at runtime to help debug

    var pic1 = new Bitmap(test.bitmapData);
            addChild(pics[i])
            pic1.scaleX = 0.138427734375;
            pic1.scaleY = 0.1384114583333333;
            pic1.x = 204;
            pic1.y = 20.6;
            pic1.alpha = .25;

            var pic2:Bitmap = new Bitmap(test.bitmapData);
            pic2.x =100;
            pic2.y =100;
            pic2.scaleX =.33;
            pic2.scaleY=.33;
            addChild(pic2);            
            loaders[i].contentLoaderInfo.removeEventListener(Event.COMPLETE,     
            loadComplete)
        }
}

for循环的设置方式是，它将尝试迭代装入器实例的每个属性，这不是您想要的。您可能还需要研究其他AS3批量加载程序选项，因为已经有一些脚本可以帮助您解决这个问题

你的循环应该是这样的

for(var i=0; i<loaders.length; i++)
{
    var curLoader = loaders[i].load(Requests[i]);

（变量i=0；i）的
