自己写的三个效果，一个是逐渐消失，一个是移动离开，一个是转动离开

小菜刚上手，写了三个flex里面已经有的效果。请大家不要见笑   package org.effect { /* * 渐渐消失效果 */ import flash.display.Sprite; import flash.events.TimerEvent; import flash.utils.Timer; public class Fade {    private var tdisplay:Sprite;    private var ttime:Number;    private var setTime:Timer;       public function Fade(display:Sprite,time:Number)    {     this.tdisplay=display;     this.ttime=time;         this.setTime=new Timer(this.ttime,30);     this.setTime.addEventListener(TimerEvent.TIMER,onClick);     this.setTime.addEventListener(TimerEvent.TIMER_COMPLETE,remove);     this.setTime.start();    }       private function onClick(event:TimerEvent):void{     this.tdisplay.alpha=(this.ttime-event.target.currentCount)/this.ttime;    }       private function remove(evt:TimerEvent):void{     this.tdisplay.parent.removeChild(this.tdisplay);    } } }     package org.effect { /* * 移动离开效果 */ import flash.display.Sprite; import flash.events.TimerEvent; import flash.utils.Timer; public class Move {    private var tdisplay:Sprite;    private var ttime:Number;    private var setTime:Timer;       public function Move(display:Sprite,time:Number)    {     this.tdisplay=display;     this.ttime=time;         this.setTime=new Timer(this.ttime,30);     this.setTime.addEventListener(TimerEvent.TIMER,onClick);     this.setTime.addEventListener(TimerEvent.TIMER_COMPLETE,remove);     this.setTime.start();    }       private function onClick(event:TimerEvent):void{     this.tdisplay.x=(event.target.currentCount/this.ttime)*2000;    }       private function remove(evt:TimerEvent):void{     this.tdisplay.parent.removeChild(this.tdisplay);    } } }   package org.effect { /* * 转动消失效果 */ import flash.display.Sprite; import flash.events.TimerEvent; import flash.utils.Timer; public class Rotation {    private var tdisplay:Sprite;    private var ttime:Number;    private var setTime:Timer;       public function Rotation(display:Sprite,time:Number)    {     this.tdisplay=display;     this.ttime=time;         this.setTime=new Timer(this.ttime,100);     this.setTime.addEventListener(TimerEvent.TIMER,onClick);     this.setTime.addEventListener(TimerEvent.TIMER_COMPLETE,remove);     this.setTime.start();    }       private function onClick(event:TimerEvent):void{     this.tdisplay.rotation=(event.target.currentCount/this.ttime)*180;    }       private function remove(evt:TimerEvent):void{     this.tdisplay.parent.removeChild(this.tdisplay);    } } }   其实三个效果都是同一个做法，就是用timer类，让 timer每隔一定时间，修改一下对象的属性。
