as3 根据鼠标移动方向

gz 为一个影片

import flash.display.Sprite;
stage.addEventListener(MouseEvent.MOUSE_MOVE, onStageMouseMoveHandle);
function onStageMouseMoveHandle(evt:MouseEvent):void
{
	if (gz.parent as Sprite)
	{
		var parentObj:Object=gz.parent;

		gz.rotation = 180 / Math.PI * Math.atan2(parentObj.mouseY - gz.y,parentObj.mouseX - gz.x);
	}
}
