AS3程序：Kclock（Flash 时钟）

个人总结：
1、AS3代码规范和习惯和之前的AS1，AS2是完全不同的，变得太多了！
2、比较欣赏AS3中的document class引用，能够完全做到界面和代码完全分离！界面在Kclock.fla文件里，所有的代码都在Kclock.as代码文件里！爽吧!
3、AS1，AS2是通过attachMovie方法把库里（通过Linkage中的关键字）的MC加载到场景中的，AS3则是将把库里（通过Linkage中的类）的MC，将其看作一个类，通用new 类名的方式，再通过addChild方法把它加载到场景中。这个是完全和原来不一样了！
4、用Timer类来代替原来的setInterval方法，这个到我原来写过的Thread类很类似的（激动一下）!
5、这个程序我花了一个下午的时间写出来的，属于一个习作，为了感受一下AS3！对于原来的flash开发者来说：就是把习惯进行根本 转变一下！

Kclock代码：

package {       import flash.display.Sprite;       import flash.events.TimerEvent;       import flash.utils.Timer;       public class Kclock extends Sprite {             public var ticker:Timer;       public function Kclock() {             this.drawFace();             this.drawHand();             this.update();             this.ticker = new Timer(1000);             this.ticker.addEventListener(TimerEvent.TIMER, onTick);             this.ticker.start();       }       private function drawFace():void{             var face:Face = new Face();             face.x = 150;             face.y = 150;             face.name = "face";             this.addChild(face);       }       private function drawHand():void{             var sec:SecondHand = new SecondHand();             sec.x = 150;             sec.y = 150;             sec.name = "sec";             this.addChild(sec);             var min:MinuteHand = new MinuteHand();             min.x = 150;             min.y = 150;             min.name = "min";             this.addChild(min);             var hou:HourHand = new HourHand();             hou.x = 150;             hou.y = 150;             hou.name = "hou";             this.addChild(hou);             var cen:Center = new Center();             cen.x = 150;             cen.y = 150;             cen.name = "cen";             this.addChild(cen);       }       public function onTick(evt:TimerEvent):void{             this.update();       }       private function update():void{             var today:Date = new Date();             var len:uint = this.numChildren;             for(var i:uint = 0;i<len;i++){                   var clild:Sprite = this.getChildAt(i) as Sprite;                   switch(clild.name){                         case "sec":                                     clild.rotation = today.getSeconds()*6;                                     break;                         case "min":                                     clild.rotation = today.getMinutes()*6;                                     break;                         case "hou":                                     clild.rotation = (today.getHours() * 30) + (today.getMinutes() * 0.5);                                     break;                   }             }       } } }
