flash3.0中，鼠标点击任意一个元件后，再点击任意一个元件，两个元件就会交换位置的代码怎样写？

舞台上有9个影片剪辑，有两帧，第一帧加stop();

实例名分别为mc1/mc2/mc3...mc9

在帧上加如下代码：

import fl.transitions.Tween;
import fl.motion.easing.Quadratic;
import fl.transitions.TweenEvent;

var time:Number=0.3;//切换时间
var startId:int=0;
var endId:int=0;
var clickCount:int=0;
var isMove:Boolean=false;
var tweenAry:Array=new Array();
for(var i:int=1;i<10;i++)
{
	this["mc"+i].addEventListener(MouseEvent.CLICK,MouseClickEvent);
}
function MouseClickEvent(e:MouseEvent):void
{
	var obj:Object=e.currentTarget;
	var t:int=int(obj.name.slice(2));
	if(t==startId||t==endId)
	{
		obj.gotoAndStop(1);
		clickCount--;
		if(t==startId)
		{
			startId=0;
		}
		else if(t==endId)
		{
			endId=0;
		}
		return;
	}
	obj.gotoAndStop(2);
	if(clickCount==0)
	{
		startId=t;
	}
	else
	{
		endId=t;
	}
	clickCount++;
	if(clickCount==2)
	{
		isMove=true;
		tweenAry.push(new Tween(this["mc"+startId], "x", Quadratic.easeInOut, this["mc"+startId].x,this["mc"+endId].x,time, true));
		tweenAry.push(new Tween(this["mc"+startId], "y", Quadratic.easeInOut, this["mc"+startId].y,this["mc"+endId].y,time, true));
		tweenAry.push(new Tween(this["mc"+endId], "x", Quadratic.easeInOut, this["mc"+endId].x,this["mc"+startId].x,time, true));
		tweenAry.push(new Tween(this["mc"+endId], "y", Quadratic.easeInOut, this["mc"+endId].y,this["mc"+startId].y,time, true));
		tweenAry[tweenAry.length-1].addEventListener(TweenEvent.MOTION_FINISH,MoveEndEvent);
	}
}
function MoveEndEvent(e:TweenEvent):void
{
	isMove=false;
	this["mc"+startId].gotoAndStop(1);
	this["mc"+endId].gotoAndStop(1);
	clickCount=0;
	startId=0;
	endId=0;
}
