脱衣服游戏制作

不要误会，这只是用来交流用的！脱衣服这个游戏，用到了很多bitmapData,以及一些AS对于图片渲染的一些API，所以自己做了一个，把源代码发上来，以供参考。

package
{
    import flash.display.Bitmap;
    import flash.display.BitmapData;
    import flash.display.BlendMode;
    import flash.display.Sprite;
    import flash.display.StageAlign;
    import flash.display.StageScaleMode;
    import flash.events.MouseEvent;
    import flash.geom.Matrix;
    import flash.geom.Rectangle;
    
    public class TuoYi extends Sprite
    {
        //背景素材
        [Embed(source="res/girl.jpg")] var Pic:Class;
        private var background:Bitmap = new Pic();        
        //遮挡数据
        private var bmd:BitmapData = new BitmapData(stage.fullScreenWidth,stage.fullScreenHeight,
true,0);
        //遮挡数据图片
        private var bm:Bitmap = new Bitmap(bmd);
        //看不见的画板
        private var drawCanvas:Sprite = new Sprite();

        public function TuoYi()
        {
            super();
            // support autoOrients
            stage.align = StageAlign.TOP_LEFT;
            stage.scaleMode = StageScaleMode.NO_SCALE;
            
            //设置背景
            this.addChild(background);
            background.width = stage.fullScreenWidth;
            background.height = stage.fullScreenHeight;
            this.mouseEnabled = false;
            
            //画出的看不见的画板的颜色病添加到图形上，并设置BlendMode.LAYER
            drawCanvas.graphics.beginFill(0xff0000);
            drawCanvas.graphics.lineStyle(20,0xff0000);
            drawCanvas.graphics.drawRect(0,0,stage.fullScreenWidth,stage.fullScreenHeight);
            this.addChild(bm);
            //将区域编程红色
            bmd.draw(drawCanvas,null,null,BlendMode.LAYER);
            
            //添加各种监听事件
            stage.addEventListener(MouseEvent.MOUSE_DOWN,onMouseDown);
         　stage.addEventListener(MouseEvent.MOUSE_UP,onMouseUp);
            
            //性能监视
            stage.addChild(new Stats());
        }
        protected function onMouseUp(event:MouseEvent):void
        {
            stage.removeEventListener(MouseEvent.MOUSE_MOVE,onMouseMove);
        }
        protected function onMouseMove(event:MouseEvent):void
        {
            drawCanvas.graphics.lineTo(this.mouseX,this.mouseY);
            bmd.draw(drawCanvas,null,null,BlendMode.ERASE);
        }
        protected function onMouseDown(event:MouseEvent):void
        {
            drawCanvas.graphics.clear();
            drawCanvas.graphics.lineStyle(40,0);
            drawCanvas.graphics.moveTo(this.mouseX,this.mouseY);
            stage.addEventListener(MouseEvent.MOUSE_MOVE,onMouseMove);
        }
    }
