classe dos objetos:

function criaObjetos():void
{
   for(var i:uint; i!=10; i++)
   {
      var quadrado:Sprite = new Sprite();
      quadrado.addEventListener(MouseEvent.MOUSE_OVER, MenuEffects.over);
      quadrado.addEventListener(MouseEvent.MOUSE_OUT, MenuEffects.out);
      quadrado.addEventListener(MouseEvent.MOUSE_CLICK, MenuEffects.click);
   }
}


classe de eventos:
function over(event:MenuEvent):void
{
    TweenMax.addTween(event.currentTarget, {xscale:1.2});
    TweenMax.addTween(event.currentTarget, {yscale:1.2});
}

function out(event:MenuEvent):void
{
    TweenMax.addTween(event.currentTarget, {xscale:1});
    TweenMax.addTween(event.currentTarget, {yscale:1});
}

function click(event:MenuEvent):void
{
// click
}
