TweenLite使用一例

TweenLite的效果：

fla代码：

 var a:runPic=new runPic("http://images.cnblogs.com/cnblogs_com/ddw1997/img/yaoming.jpg");
2 addChild(a);
3 a.addEventListener(runPic.LOADER_EVENT,set_xy);
4 function set_xy(e:Event ):void {
5     a.x=(stage.stageWidth-a.width)/2;
6     a.y=(stage.stageHeight-a.height)/2;
7     a.removeEventListener(runPic.LOADER_EVENT,set_xy);
8 }

runPic.as

 1 /*===========================================================
 2 * 构造函数有五个参数，第一个是图片地址是必需的。
 3 * var a:runPic=new runPic("yaoming.jpg");
 4 * addChild(a);
 5 * a.addEventListener(runPic.LOADER_EVENT,set_xy);
 6 * function set_xy(e:Event ):void {
 7 * a.x=(stage.stageWidth-a.width)/2;
 8 * a.y=(stage.stageHeight-a.height)/2;
 9 * a.removeEventListener(runPic.LOADER_EVENT,set_xy);
10 * }
