Actionscript 3 在变量中存储y坐标

我正试图用鼠标点击一个电影剪辑的y位置。到目前为止，我有这个代码

import fl.transitions.Tween;

import fl.transitions.easing.*;


var posY:Number = infographic_mc.y
var redY:Number = -232
var orangeY:Number = -551
var yellowY:Number = -883
var greenY:Number = -1225
var blueY:Number = -1543
var purpleY:Number = -1873

var tween1:Tween = new Tween(infographic_mc, "y", Regular.easeOut, posY, redY, 2, true);
var tween2:Tween = new Tween(infographic_mc, "y", Regular.easeOut, posY, orangeY, 2, true);
var tween3:Tween = new Tween(infographic_mc, "y", Regular.easeOut, posY, yellowY, 2, true);
var tween4:Tween = new Tween(infographic_mc, "y", Regular.easeOut, posY, greenY, 2, true);
var tween5:Tween = new Tween(infographic_mc, "y", Regular.easeOut, posY, blueY, 2, true);
var tween6:Tween = new Tween(infographic_mc, "y", Regular.easeOut, posY, purpleY, 2, true);

tween1.stop();
tween2.stop();
tween3.stop();
tween4.stop();
tween5.stop();
tween6.stop();

red_btn.addEventListener(MouseEvent.CLICK, redButtonClick);  
orange_btn.addEventListener(MouseEvent.CLICK, orangeButtonClick);  
yellow_btn.addEventListener(MouseEvent.CLICK, yellowButtonClick);  
green_btn.addEventListener(MouseEvent.CLICK, greenButtonClick);  
blue_btn.addEventListener(MouseEvent.CLICK, blueButtonClick);  
purple_btn.addEventListener(MouseEvent.CLICK, purpleButtonClick);  


function redButtonClick(event:MouseEvent):void {

tween1.start();

 }


function orangeButtonClick(event:MouseEvent):void {

tween2.start();
}


function yellowButtonClick(event:MouseEvent):void {

tween3.start();
}


function greenButtonClick(event:MouseEvent):void {

tween4.start();
}


function blueButtonClick(event:MouseEvent):void {

tween5.start();
}


function purpleButtonClick(event:MouseEvent):void {

tween6.start();
}

这是可行的，但它不会在一个tween之后存储Y坐标，并且每个tween都返回到开始

有没有办法更新在鼠标单击函数中存储Y坐标的变量？

您可以使用一个变量来存储当前的Y坐标，而不是在开始时创建所有的Y坐标

var currentTween:Tween; 

然后，在每个事件侦听器中，您可以根据信息图的当前位置创建您当前的tween。代码如下所示：

function redButtonClick(event:MouseEvent):void {
   if(currentTween) currentTween.stop(); //if there is a current tween animating, stop it

   currentTween = new Tween(infographic_mc, "y", Regular.easeOut, infographic_mc.y, redY, 2, true);

   currentTween.start();
}

此外，我建议为所有按钮使用一个处理函数，而不是单独的函数，并使用switch语句来确定单击了哪个按钮。此外，如果您计划在应用程序中使用大量动画，请查看GreenSock库中的tweening，因为它具有更好的性能
