   should I run the code in Flash CS4 or Flex Builder 3.0?
   I tried it in Flash and it won’t run. Please help. Thanks.

   Xmas2009.as is the main file of a Flex Builder AS3 project.
   In flash you could use it by cleaning up a little. You could remove stuff like [SWF(width="400", height="600", backgroundColor=0x000033, frameRate="60")] or the embed tags, save it as a class and instance it from a simple fla, or associate the class to the fla file itself.

   I tried to use “Xmas2009.as” as document class for “lights.fla” but it still won’t work.
   What did I do wrong. Pls help. Thanks.

   package
   {
   import flash.display.Sprite;
   import flash.display.MovieClip;
   import flash.events.Event;

   import flash.filters.GlowFilter;

   public class Xmas2009 extends MovieClip
   {
   private var lights:Sprite;
   private const INIT_RADIUS:Number=150;
   private const MAX_ROTATION_X:Number=20;

   private var light1_class:light1 = new light1();
   private var light2_class:light2 = new light2();
   private var light3_class:light3 = new light3();
   private var light4_class:light4 = new light4();

   public function Xmas2009()
   {
   lights = new Sprite();
   lights.x = 200;
   lights.y = 250;
   lights.filters = [new GlowFilter(0xffcc00, 1, 12, 12, 2, 1)];

   prepare(light1_class, lights, 170, 18, 120);
   prepare(light2_class, lights, 100, 2, 20);
   prepare(light4_class, lights, 100, 2, 20, 180);
   prepare(light3_class, lights, 160, 31, 50);

   addChild(lights);
   addEventListener(Event.ENTER_FRAME, onframe);
   }

   private function onframe(event:Event):void
   {
   var sy:Number = (mouseX-200)/80;
   lights.rotationY += sy;
   correctOrientations(lights);
   }

   private function correctOrientations($target:Sprite):void
   {
   var c:Sprite;
   for(var i:uint=0; i<$target.numChildren; i++) {
   c=$target.getChildAt(i) as Sprite;
   c.rotationY=-$target.rotationY;
   c.rotationX=-$target.rotationX;
   }
   }

   public function prepare(className:Class, target:Sprite, count:uint, revolutions:uint, lightInterval:uint, initialAngle:Number=0):void
   {
   var a:Number = initialAngle;
   var arad:Number, l:Light, yspan:Number, r:Number;

   for (var i:int=0; i<count; i++) {
   r = INIT_RADIUS/count*i;
   a += (360*revolutions)/count;
   arad = a/180*Math.PI;

   l = new Light(className, lightInterval*i);
   l.x = Math.cos(arad)*r;
   yspan = 400/count;
   l.y = i*yspan-200;
   l.z = Math.sin(arad)*r;
   target.addChild(l);
   }
   }

   }
   }

    private var light1_class:light1 = new light1();
    private var light2_class:light2 = new light2();
    private var light3_class:light3 = new light3();
    private var light4_class:light4 = new light4();

    you create an instance for every light asse available in the library, but the class Light.as just wants the reference to the class not an instance of that class. It’s the class which provides to the instancing. This works:

    private var light1_class:Class = light1;
    private var light2_class:Class = light2;
    private var light3_class:Class = light3;
    private var light4_class:Class = light4;

    Cheers
