技能冷却动画转圈圈
方法一：
package ui{ import flash.display.Graphics; import flash.display.Sprite; import flash.events.Event; import flash.geom.Point; import flash.utils.getTimer; /** * * @author whh * * 用法: * duration:旋转一圈需要时间 * length:圆的半径 * start()开始 * * 如: * var a:Circle = new Circle() * a.duration = 20000; * a.start(); */ public class Circle extends Sprite { public function Circle() { graph = this.graphics; tempPoint = new Point(0,-length); } public var duration:int; public var length:int = 20; private var tempPoint : Point private var graph:Graphics; private var startTime:int; public function start():void { graph.clear(); startTime = getTimer(); this.addEventListener(Event.ENTER_FRAME,enterFrameHandler); } private function enterFrameHandler(event:Event):void { var t:Number = getTimer() - startTime; if(t>duration) { this.removeEventListener(Event.ENTER_FRAME,enterFrameHandler); draw(360); return; } draw(t/duration * 360); } private function draw(angle:Number):void { var temp:Number = (angle-90)*Math.PI/180; graph.beginFill(0xFF0000); var ca:Number = Math.cos(temp)*length; var sa:Number = Math.sin(temp)*length; graph.moveTo(0,0); graph.lineTo(tempPoint.x,tempPoint.y); graph.lineTo(ca,sa); graph.lineTo(0,0); tempPoint.x = ca; tempPoint.y = sa; graph.endFill(); } }}?方法二：
private var cool:Sprite;private var sector:Spriteprivate var timerId:int;private var timeCount:int;private var angle:int;private var timeSpace:int;public var coolStatus:Boolean;/** * 设置冷却时间 * */public function setCool(time:int=2000):void{if (_lock)return;if (!cool){cool=new Sprite();sector=new Sprite();}addChild(cool);addChild(sector);cool.graphics.clear();cool.graphics.beginFill(0xff0000, 0.5);cool.graphics.drawRect(0, 0, this.width, this.height);cool.graphics.endFill();angle=0;timeCount=time;timeSpace=time / 30;timerId=CatchSetInterval(coolCal, timeSpace);coolStatus=true;}private function coolCal():void{sector.graphics.clear();timeCount-=timeSpace;angle+=12;Tools.DrawHPMPSector(sector, this.width / 2, this.height / 2, 25, 360 - angle, 270 + angle);cool.mask=sector;dragFrom=false;if (timeCount <= 0){clearInterval(timerId);removeChild(cool);removeChild(sector);dragFrom=true;coolStatus=false;}}?
