AS3基础，鼠标追随

AS3基础，鼠标跟随

我们经常在游戏里看到，人物跟随鼠标的点击旋转并移动位置，其实算法还是比较简单的。

package{import flash.display.Sprite;import flash.events.Event;import flash.events.MouseEvent;public class Main extends Sprite{private var musX:Number;private var musY:Number;private var rect:Rect;public function Main(){rect=new Rect();addChild(rect);this.addEventListener(Event.ENTER_FRAME,onEnterFrame);this.stage.addEventListener(MouseEvent.CLICK,clickHandler);}private function onEnterFrame(e:Event):void{var dx:Number=mouseX-rect.x;var dy:Number=mouseY-rect.y;var radians:Number=Math.atan2(dy,dx);rect.rotation=radians*180/Math.PI+0;}private function clickHandler(e:MouseEvent):void{musX=e.stageX;musY=e.stageY;trace(musX);rect.x+=(musX-rect.x)/5;rect.y+=(musY-rect.y)/5;}}}
