flash 游戏设计笔记：bitmap.bitmapData.hitTest使用

var bitmap:Bitmap=AssetHelp.getItemsIcon("doctor1");bitmap.name="bit";var imageSp:Sprite = new Sprite();imageSp.addChild(bitmap);imageSp.addEventListener(MouseEvent.MOUSE_OVER, mouseOver1);imageSp.addEventListener(MouseEvent.MOUSE_MOVE, mouseMove);imageSp.addEventListener(MouseEvent.MOUSE_OUT, mouseOut1);this.addChild(imageSp);private var fitArr:Array = [new GlowFilter(PlayerUtil.YELLOW,1,10,10)];public function mouseMove(e:MouseEvent):void{var sp:Sprite = e.currentTarget as Sprite;changeImage(sp);}public function mouseOver1(e:MouseEvent):void{var sp:Sprite = e.currentTarget as Sprite;changeImage(sp);}public function mouseOut1(e:MouseEvent):void{e.currentTarget.filters = [];}private function changeImage(sp:Sprite):void{var local:Point = sp.globalToLocal(new Point(stage.mouseX,stage.mouseY));var bitmap:Bitmap = sp.getChildByName("bit") as Bitmap;var b:Boolean =bitmap.bitmapData.hitTest(new Point(0,0),1,new Point(local.x, local.y));trace(b);if(b){sp.filters = fitArr;}else {sp.filters = [];}}
