        private var tWidth:int = 30;
        private var tHeight:int = 30;
        private var tImage:BitmapData;
        private var canvas:Bitmap;

        private var p:Point;
        private var r:Rectangle;    

        public function Tile():void
        {
            var tempImage:BitmapData = tileImage;
            r = new Rectangle(0,0,30,30);
            p = new Point(0,0);
            tImage = new BitmapData(30,30);
            tImage.copyPixels(tempImage,r,p);
        }

我收到以下错误:

ArgumentError: Error #2015: Invalid BitmapData.

当我复制像素时往往会发生这种情况。我不知道为什么。

tileImage;

tileImage 是有效的,我在下面的代码中使用了该变量并且它可以工作。但上面没有。不知道为什么。有人有任何线索吗?

this.graphics.beginBitmapFill(tileImage);
this.graphics.drawRect(60, 0,tWidth ,tHeight );

没关系,我想了一个更好的解决方案

                theMatrix.translate(30,0);
        this.graphics.beginBitmapFill(tileImage,theMatrix);
        //this.graphics.drawRect(0, 0,tWidth ,tHeight );
        this.graphics.endFill();

使用 theMatrix.translates 可以让您选择所需的瓷砖部分,而不会影响精灵的位置
