fl.transitions.Tween在ActionScript Mobile項目上找不到

Question

我正在開發面向Android的ActionScript移動項目。

當我添加下面的導入時，編譯器說沒有找到。

import fl.transitions.Tween; 

如何在移動項目中使用Tween？

package{ 
    import flash.display.Sprite; 
    import flash.text.TextField; 
    import flash.events.MouseEvent; 
    import fl.transitions.Tween; 
    import fl.transitions.easing.Strong; 

    public class spriteButton extends Sprite 
    { 
     private var alphaOver:Tween; 
     private var alphaLabelOver:Tween; 
     private var alphaLabel:Tween; 

     public function spriteButton(newLabel:String) 
     { 
      myLabel.text = newLabel; 
      myLabelOver.text = newLabel; 
      myLabelOver.alpha = 0; 
      buttonMode = true; 
      mouseChildren = false; 
      addEventListener(MouseEvent.MOUSE_OVER, handleMouseOver); 
      addEventListener(MouseEvent.MOUSE_OUT, handleMouseOut); 
      addEventListener(MouseEvent.MOUSE_UP, handleMouseUp); 
     } 

順便說一下，我對ActionScript 3.0開發很新。

我得到這個錯誤：

The import fl could not be found. 
The import Tween could not be found.

如果你是新的AS3，然後使用這個庫：http://www.greensock.com/tweenmax/爲tweenning對象。
