目前挺流行这个的，其实就是Stage获得宽高，再使用的transitions.easing完成移动。
　　可以随浏览器或者FlashPlayer改变大小而适应，一般是以相对坐标来完成各分辨率效果。如果加以利用应是非常绚的效果。

全屏查看，改变浏览器尺寸试试

Stage.showMenu = false; var msize = new Object(); msize.onResize = function() {  movesize(); }; Stage.scaleMode = "noScale"; Stage.align = "tl"; Stage.addListener(msize); movesize(); function movesize() {  new mx.transitions.Tween(a1, "_x", mx.transitions.easing.Regular.easeOut, a1._x, 40, 18, false);  new mx.transitions.Tween(a1, "_y", mx.transitions.easing.Regular.easeOut, a1._y, 40, 18, false);  new mx.transitions.Tween(a2, "_x", mx.transitions.easing.Regular.easeOut, a2._x, Stage.width-a2._width-40, 18, false);  new mx.transitions.Tween(a2, "_y", mx.transitions.easing.Regular.easeOut, a2._y, 40, 18, false);  new mx.transitions.Tween(a3, "_x", mx.transitions.easing.Regular.easeOut, a3._x, 40, 18, false);  new mx.transitions.Tween(a3, "_y", mx.transitions.easing.Regular.easeOut, a3._y, Stage.height-a3._height-40, 18, false);  new mx.transitions.Tween(a4, "_x", mx.transitions.easing.Regular.easeOut, a4._x, Stage.width-a4._width-40, 18, false);  new mx.transitions.Tween(a4, "_y", mx.transitions.easing.Regular.easeOut, a4._y, Stage.height-a4._height-40, 18, false);  new mx.transitions.Tween(aa, "_x", mx.transitions.easing.Regular.easeOut, aa._x, Stage.width/2-aa._width/2, 18, false);  new mx.transitions.Tween(aa, "_y", mx.transitions.easing.Regular.easeOut, aa._y, Stage.height/2-aa._height/2, 18, false); }
