为了清晰起见,已编辑:我想在for循环中从外部网址加载各种图像。 我想在循环中调用它们,当它结束时我再次启动循环。但是我不想再用“http请求”再次调用它们,而是我想一遍又一遍地遍历加载的图像。
是否可以在循环中创建动态Loader名称?
以下是代码示例:
var Count = 0;
// Loop Begins
var Count:Loader = new Loader();
Count.load(new URLRequest("myurl");
addChild(Count);
Count++;
// End Loop
另一个例子是拥有一个NAME,并在最后添加数字。但是如何
var Count = 0;
// Loop Begins
var MyName+Count:Loader = new Loader();
MyName+Count.load(new URLRequest("myurl");
addChild(MyName+Count);
Count++;
// End Loop
简而言之: 我想将一堆图像加载到一个数组中,然后通过调用它们来遍历加载的图像。
非常感谢!

现在我们在同一页面上:
var imgArray:Array = new Array;
var totalImages:int = 42;
var totalLoaded:int = 0;
var loaded:Boolean = false;
function loadImages():void{
for(var count:int = 0; count < totalImages; count++){
var image:Loader = new Loader();
image.load(new URLRequest("image" + i + ".jpg");
image.addEventListener(Event.COMPLETE, loaded);
imgArray.push(image);
}
}
function loaded(e:Event):void{
totalLoaded++;
if (totalLoaded == totalImages){
loaded = true;
}
}
function displayImages():void{
if (loaded){
for(var i:int = 0; i < imgArray.length(); i++){
addChild(imgArray[i]);
}
}
}

CASE1代码是如何在序列中加载图像。
CASE2代码是如何在Synchronized中加载图像。
首先,您要导入所有图像的URL必须按顺序命名。 例如,必须采用以下格式:
www.myURL.com/img0.jpg
www.myURL.com/img1.jpg
www.myURL.com/img2.jpg
www.myURL.com/img3.jpg
www.myURL.com/img4.jpg
www.myURL.com/img5.jpg
.
.
.
请尝试下面的代码,只是测试。
CASE1
强> var imgLoader:Loader;
var imgRequest:URLRequest;
var count:int = -1;
const TOTAL_COUNT:int = 10;
var imgBox:Array = [];
var isCounting:Boolean;
function loadImage():void
{
count ++;
isCounting = true;
imgLoader = new Loader();
imgRequest = new URLRequest();
imgRequest.url = "www.myURL.com/img" + count +".jpg";
imgLoader.load(imgRequest);
imgLoader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, unloadedImg);
imgLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onLoadedImg);
if(count == TOTAL_COUNT)
{
isCounting = false;
count = -1;
}
}
function onLoadedImg(e:Event):void
{
imgLoader.contentLoaderInfo.removeEventListener(Event.COMPLETE, onLoadedImg);
var bmp:Bitmap = e.currentTarget.content;
bmp.x = Math.random() * width;
bmp.y = Math.random() * height;
bmp.width = 100;
bmp.height = 100;
this.addChild(bmp);
imgBox.push(bmp);
if( isCounting == false)
{
return;
}
loadImage();
}
function unloadedImg(e:IOErrorEvent):void
{
imgLoader.contentLoaderInfo.removeEventListener(IOErrorEvent.IO_ERROR, unloadedImg);
trace("load Failed:" + e);
}
loadImage();
CASE2
强> var imgLoader:Loader;
var imgRequest:URLRequest;
const TOTAL_COUNT:int = 10;
var imgBox:Array = [];
function loadImage2():void
{
for(var i:int = 0; i<TOTAL_COUNT; i++)
{
imgLoader = new Loader();
imgRequest = new URLRequest();
imgRequest.url = "www.myURL.com/img" + i +".jpg";
imgLoader.load(imgRequest);
imgLoader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, unloadedImg);
imgLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onLoadedImg);
}
}
function onLoadedImg(e:Event):void
{
imgLoader.contentLoaderInfo.removeEventListener(Event.COMPLETE, onLoadedImg);
var bmp:Bitmap = e.currentTarget.content;
bmp.x = Math.random() * width;
bmp.y = Math.random() * height;
bmp.width = 100;
bmp.height = 100;
this.addChild(bmp);
imgBox.push(bmp);
}
function unloadedImg(e:IOErrorEvent):void
{
imgLoader.contentLoaderInfo.removeEventListener(IOErrorEvent.IO_ERROR, unloadedImg);
trace("load Failed:" + e);
}
loadImage2();
如果要访问加载的图像。请参考以下代码。如果你不把它们放在一个数组中将来就无法访问。
for(var int:i=0; i<TOTAL_COUNT; i++)
{
var bitmap:Bitmap = imgBox[i] as Bitmap;
trace("index: " + i + "x: " + bitmap.x + "y: " + bitmap.y, "width: " + bitmap.width + "height: " + bitmap.height);
}
