Question

这是我游戏的关卡选择器。你可以选择1-8级，我需要知道哪一个被点击了。 e.target除了对象的名称外没有给我太多。我需要知道数组中的位置或图片的名称，以便我知道要加载哪个级别。

    import flash.display.Bitmap;
    import flash.display.DisplayObject;

    public class LevelSelector extends Sprite 
    {
        private var posX:int = 50;
        private var posY:int = 50;

        [Embed(source="../lib/one.png")]
        private var lvl1Class:Class;

        private var myArrayBitmaps:Array = new Array;
        private var myArraySprites:Array = new Array;

        private var yCounter:int = 1;

        public function LevelSelector():void 
        {
            if (stage) init();

            // entry point

            myArrayBitmaps.push(false, lvl1, lvl2, lvl3, lvl4, lvl5, lvl6, lvl7, lvl8);

            for (var i:int = 1; i < 9; i++) 
            {
                myArrayBitmaps[i].x = posX;
                myArrayBitmaps[i].y = posY;
                myArrayBitmaps[i].height = 50;
                myArrayBitmaps[i].width = 100;

                //myArraySprites[i].name = "lvl_" + i + "";

                stage.addChild(myArraySprites[i]);

                myArraySprites[i].addEventListener(MouseEvent.CLICK, function(e:MouseEvent):void {
                    removeThis(e, this);
                });

                posX += 100;
                yCounter += 1;
                if (yCounter == 5) {
                    posY += 100;
                    posX -= 400;
                }
            }
        }
        private function removeThis(e:MouseEvent, temp):void
        {
            //Need to know the number which was passed, 1-8
        }
    }
}

我会做这样的事情：

//...
private function init(e:Event = null):void 
{
    //...
    for (var i:int = 1; i < 9; i++) 
    {
        //...
        myArraySprites[i] = new Sprite();
        myArraySprites[i].addChild(myArrayBitmaps[i]);
        //...
        stage.addChild(myArraySprites[i]);

        myArraySprites[i].addEventListener(MouseEvent.CLICK, removeThis);


        }
    }
}
private function removeThis(e:MouseEvent):void
{
    var clickTarget:int = myArraySprites.indexOf(e.currentTarget);
    trace("Clicked sprite (id): " + clickTarget);
}

需要知道点击了哪个精灵
