ayuda para convertir as2 to as3

[kbito2000]

Hola pueden ayudarme a adaptar este codigo en as2 para as3?? por favorrrrrrrrrrrrrrrrrrrrrrrrr tengo una exposicion en 3 horas y necesito solo ese codigo adaptado a as3 por que me manda errores al ejecutarlo

Código:

import mx.transitions.Tween;
import mx.transitions.easing.*;
var oriX:Number = Stage.width/2;
var oriY:Number = Stage.height/2;
var mcHolder:MovieClip = this.createEmptyMovieClip('mcHolder', this.getNextHighestDepth());
mcHolder._x = oriX;
mcHolder._y = oriY;
var mcMapa:MovieClip = mcHolder.attachMovie('mcMapa', 'mcMapa', mcHolder.getNextHighestDepth());
mcMapa._x = mcMapa._width/-2;
mcMapa._y = mcMapa._height/-2;
mcMapa.useHandCursor = false;
mcMapa.onRelease = function() {
	var speed:Number = .2;
	var initX:Number = this._x;
	var endX:Number = -oriX-this._xmouse+Stage.width/2;
	if (endX>-oriX) {
		endX = -oriX;
	}
	if (endX<Stage.width-this._width-oriX) {
		endX = Stage.width-this._width-oriX;
	}
	var twX:Tween = new Tween(this, '_x', Back.easeOut, initX, endX, speed, true);
	var initY:Number = this._y;
	var endY:Number = -oriY-this._ymouse+Stage.height/2;
	if (endY>-oriY) {
		endY = -oriY;
	}
	if (endY<Stage.height-this._height-oriY) {
		endY = Stage.height-this._height-oriY;
	}
	var twY:Tween = new Tween(this, '_y', Back.easeOut, initY, endY, speed, true);
};
var speed:Number = .5;
var ratio:Number = 16;
var maxZoom:Number = 500;
var bolZoom:Boolean = false;
var lst:Object = new Object();
lst.onMouseWheel = function(delta) {
	var initS:Number = mcHolder._xscale;
	var endS:Number = mcHolder._xscale+(delta*ratio);
	if (delta<0) {
		if (mcHolder._width>Stage.width) {
			bolZoom = true;
		} else {
			bolZoom = false;
		}
	} else if (delta>0) {
		mcMapa.enabled = true;
		if (mcHolder._xscale<maxZoom) {
			bolZoom = true;
		} else {
			bolZoom = false;
		}
	}
	if (bolZoom) {
		var twSX:Tween = new Tween(mcHolder, '_xscale', Back.easeOut, initS, endS, speed, true);
		var twSY:Tween = new Tween(mcHolder, '_yscale', Back.easeOut, initS, endS, speed, true);
		twSY.onMotionFinished = function() {
			if (mcHolder._width<Stage.width) {
				mcMapa.enabled = false;
				var twX:Tween = new Tween(mcMapa, '_x', Back.easeOut, mcMapa._x, mcMapa._width/-2, speed, true);
				var twY:Tween = new Tween(mcMapa, '_y', Back.easeOut, mcMapa._y, mcMapa._height/-2, speed, true);
			}
		};
	}
};
Mouse.addListener(lst);

esto es lo que quiero modificar

POR FAVOR!!!
