I’m using the code bellow for a menu:

```auto

//button 1
button1.addEventListener(MouseEvent.MOUSE_OVER,over);
button1.addEventListener(MouseEvent.MOUSE_OUT, out);

function over(e:MouseEvent):void{
  TweenLite.to (button1,1,{alpha:0});
 }
function out(e:MouseEvent):void{
  TweenLite.to (button1,1,{alpha:1});
}

```

The problem is that I’ll have several buttons, and I was imagining if there’s a easer, faster and cleaner way of doing the actions, since all the buttons will have the same rollover and rollout effect.

I tried to use

```auto

function over(e:MouseEvent):void{
  TweenLite.to (this,1,{alpha:0});
 }

```

but the effect takes place in all stage elements.  
Is there a way of doing the effect with Vars or another easer way?

thanks in advance.
