Tween

今天玩了一下Tween

一開始怎麼都不成功

原來是要improt一樣東西

後來就成功了
import fl.transitions.Tween;
import fl.transitions.easing.*;//這行一定要有 不然Back None 等物件無法用

paint_mc.addEventListener(MouseEvent.MOUSE_DOWN,tween);

function tween(evt:Event)
{
var filter:DropShadowFilter=new flash.filters.DropShadowFilter();
filter.blurX=20;
filter.blurY=20;
filter.angle=30;
paint_mc.filters=[filter];
var myTween:Tween = new Tween(paint_mc, "scaleX", Back.easeIn, paint_mc.scaleX, 2, 3, true);
}
