GlassWin на AS3 silin.fatal.ru

[AS3_coder]

как переписать этот класс на AS3?

import flash.filters.*;
import flash.geom.*;
import flash.display.*;

class GlassWin extends MovieClip{
	private var glassColor:Number=0xD9FFFF;
	private var glassAlpha:Number=35;
	private var mousePoint:Point;
	private var alphaScreen:MovieClip;
	private var blurScreen:MovieClip;
	private var blurBitmap:BitmapData;
	
	public function GlassWin(){
		var w:Number=Math.floor(_width);
		var h:Number=Math.floor(_height);
		var lowDepth=0;
		//всех поднимем на 2, чтоб освободить место для скринов
		for(var i in this) {
			if(this[i].getDepth()<lowDepth)lowDepth=this[i].getDepth();
			_root.swapDepths.call(this[i],this[i].getDepth()+2);
		}
		//////////////
		var bounds=getBounds(this);
		alphaScreen=this.createEmptyMovieClip("alphaScreen",lowDepth+1);
		blurScreen=this.createEmptyMovieClip("blurScreen",lowDepth);
		alphaScreen._x=blurScreen._x=bounds.xMin;
		alphaScreen._y=blurScreen._y=bounds.yMin;
		alphaScreen.beginFill(glassColor,glassAlpha);
		alphaScreen.lineTo(w,0);
		alphaScreen.lineTo(w,h);
		alphaScreen.lineTo(0,h);
		alphaScreen.endFill();
		////////
		blurBitmap=new BitmapData(w,h);
		blurScreen.attachBitmap(blurBitmap,0);
		getScreen();
		render();
	}
	
	function onPress(){
		mousePoint=new Point(_xmouse,_ymouse);
		onEnterFrame=render;
	}
	
	function onRelease(){
		onEnterFrame=null;
	}
	
	function render(){
		_x+=_xmouse-mousePoint.x;
		_y+=_ymouse-mousePoint.y;
		mousePoint=new Point(_xmouse,_ymouse);
		getScreen();
		updateAfterEvent();
	}
	
	function getScreen(){
		var p:Point=new Point(_x,_y);
		_parent.localToGlobal(p);
		var tx:Number=-(p.x+blurScreen._x);
		var ty:Number=-(p.y+blurScreen._y);
		var mtrx=new Matrix(1,0,0,1,tx,ty);
		_visible=false;
		blurBitmap.draw(_root,mtrx);
		_visible=true;
		blurBitmap.applyFilter(blurBitmap,blurBitmap.rectangle,new Point(),new BlurFilter(10,10));
	}
}

Вот что я попробовал...

package{
import flash.filters.*;
import flash.geom.*;
import flash.display.*;
import flash.events.*;

public class GlassWin extends MovieClip{
    private var glassColor:Number=0xD9FFFF;
	private var glassAlpha:Number=35;
	private var mousePoint:Point;
	private var alphaScreen:MovieClip;
	private var blurScreen:MovieClip;
	private var blurBitmap:BitmapData;
	
	public function mouseDownHandler(event:MouseEvent){
		mousePoint=new Point(mouseX,mouseY);
		addEventListener(Event.ENTER_FRAME, render);
	}
	
	public function clickHandler(){
		removeEventListener(Event.ENTER_FRAME, render);
	}
	
	public function render(e:Event){
		x+=mouseX-mousePoint.x;
		y+=mouseY-mousePoint.y;
		mousePoint=new Point(mouseX,mouseY);
		getScreen();
	}
	
	public function getScreen():void{
		var p:Point=new Point(x,y);
		parent.localToGlobal(p);
		var tx:Number=-(p.x+blurScreen.x);
		var ty:Number=-(p.y+blurScreen.y);
		var mtrx=new Matrix(1,0,0,1,tx,ty);
		visible=false;
		blurBitmap.draw(stage,mtrx);
		visible=true;
		blurBitmap.applyFilter(blurBitmap,blurBitmap.rectangle,new Point(),new BlurFilter(10,10));
	}
	
	public function GlassWin(){
	var w:Number=Math.floor(this.width);
	var h:Number=Math.floor(this.height);
		var lowDepth=0;
		//всех поднимем на 2, чтоб освободить место для скринов
		for(var i in this) {
			if(this[i].getDepth()<lowDepth)lowDepth=this[i].getDepth();
			stage.swapDepths.call(this[i],this[i].getDepth()+2);
		}
		//////////////
		var bounds=getBounds(this);
		var alphaScreen:MovieClip = new MovieClip();
		addChild(alphaScreen);
		var blurScreen:MovieClip = new MovieClip();
		addChild(blurScreen);
		alphaScreen.x=blurScreen.x=bounds.x;
		alphaScreen.y=blurScreen.y=bounds.y;
		alphaScreen.graphics.beginFill(glassColor,glassAlpha);
		alphaScreen.graphics.lineTo(w,0);
		alphaScreen.graphics.lineTo(w,h);
		alphaScreen.graphics.lineTo(0,h);
		alphaScreen.graphics.endFill();
		////////
		blurBitmap=new BitmapData(w,h);
		var blurScreen1:Bitmap = new Bitmap(blurBitmap);
		blurScreen.addChild(blurScreen1)
		getScreen();
		render();
		
		addEventListener(MouseEvent.MOUSE_DOWN, mouseDownHandler);
		addEventListener(MouseEvent.CLICK, clickHandler);
		
	}
}
}

Мой вариант не работает
