Flash / Flex / ActionScript/Animation/Timer Event

add the start() method to our program, things start happening:

   <source lang="java">

package {

   import flash.display.Sprite;
   import flash.utils.*;
   import flash.events.*;
   public class Main extends Sprite {
       public static const TIMER_DELAY:Number = 1 * 1000;
       public var timer:Timer = new Timer(TIMER_DELAY, 10);
       public function Main() {
           timer.addEventListener(TimerEvent.TIMER, onTimer);
           timer.addEventListener(TimerEvent.TIMER_COMPLETE,  onTimerComplete);
           timer.start();
       }
       private function onTimer(event:TimerEvent):void {
           trace("Tick.");
       }
       private function onTimerComplete(event:TimerEvent):void {
           trace("Ding!");
       }
   }

}

       </source>
   
  

A timer that has just five intervals:

   <source lang="java">

package{

 import flash.display.Sprite;
 import flash.utils.*;
 import flash.events.*;
 
 public class Main extends Sprite{
   public function Main(){
       var timer:Timer = new Timer(1000, 5);
   }
 }

}

       </source>
   
  

Listening for Timer Events

   <source lang="java">

package {

   import flash.display.Sprite;
   import flash.utils.*;
   import flash.events.*;
   public class Main extends Sprite {
       public static const TIMER_DELAY:Number = 1 * 1000;
       public var timer:Timer = new Timer(TIMER_DELAY, 10);
       public function Main() {
           timer.addEventListener(TimerEvent.TIMER, onTimer);
           timer.addEventListener(TimerEvent.TIMER_COMPLETE, onTimerComplete);
       }
       private function onTimer(event:TimerEvent):void {
           trace("Tick.");
       }
       private function onTimerComplete(event:TimerEvent):void {
           trace("Ding!");
       }
   }

}

       </source>
   
  

Using Timers

   <source lang="java">

package{

 import flash.display.Sprite;
 import flash.utils.*;
 import flash.events.*;
 public class Main extends Sprite{
   public function Main(){
       var timer:Timer = new Timer(1000);
       timer.addEventListener(TimerEvent.TIMER, onTimer);
       
       timer.start(  );
   }
   function onTimer(event:TimerEvent):void {
     trace("on timer");
   }
 }

}

       </source>
