   Hi guys,
   I'm trying to build a snow-like project but I want to use self-animating Sprites instead of images as particles.
   There is a Sprite object inside the Library with the linkage identifier of Balloon.
   
   package
   {
   import flash.display.MovieClip;
   import flash.display.Sprite;
   import flash.geom.Point;
   import org.flintparticles.common.counters.*;
   import org.flintparticles.common.displayObjects.RadialDot;
   import org.flintparticles.common.initializers.*;
   import org.flintparticles.twoD.actions.*;
   import org.flintparticles.twoD.emitters.Emitter2D;
   import org.flintparticles.twoD.initializers.*;
   import org.flintparticles.twoD.particles.Particle2D;
   import org.flintparticles.twoD.particles.Particle2DUtils;
   import org.flintparticles.twoD.renderers.*;
   import org.flintparticles.twoD.zones.*;
   
   /**

   */
   public class snow extends MovieClip
   {
   private var emitter:Emitter2D;
   private var renderer:DisplayObjectRenderer;
   private var dzone:RectangleZone;
   private var deathZone:DeathZone;
   
   //init effect
   public function snow()
   {
   emitter = new Emitter2D();
   emitter.counter = new Steady(30);
   
   var balPart:Particle2D = Particle2DUtils.createParticle2DFromDisplayObject(new Balloon());
   emitter.addParticle(balPart);
   
   emitter.addInitializer( new Position( new LineZone( new Point( -5, -5 ), new Point( 720, -5 ) ) ) );
   emitter.addInitializer( new Velocity( new PointZone( new Point( 30, 120 ) ) ) );
   emitter.addInitializer( new ScaleImageInit( 0.5, 4 ) );
   
   dzone = new RectangleZone( -10, -10, 740, 420 );
   deathZone = new DeathZone( dzone, true );
   emitter.addAction( deathZone );
   emitter.addAction(new Move());
   emitter.addAction( new RandomDrift( 110, 10 ));
   
   renderer = new DisplayObjectRenderer();
   renderer.addEmitter(emitter);
   addChild(renderer);
   
   emitter.runAhead(10);
   
   emitter.start();
   }
   
   public function removeEffect() //clean up ram from loader
   {
   emitter.stop();
   renderer.removeEmitter(emitter);
   emitter.killAllParticles();
   emitter = null;
   removeChild(renderer);
   }
   }
   }
   
   
   Any thoughts?
   
   Thanks in advance!

   You don't say what exactly isn't working, but on a brief look at your code it looks like you're only creating one particle, and adding it before you add all the actions to the emitter. Don't use Particle2DUtils.createParticle2DFromDisplayObject. Use the ImageClass initializer, as used in this example, but pass it your custom class as the image initializer
   
   emitter.addInitializer( new ImageClass( Balloon ) );
   This initializer will create a new instance of your custom class for each particle.

   Thanks for your help, Richard! It works perfectly now! I was afraid I'd lost the animation that occurs inside the Balloon objects (which basically extends the Sprite class but also contains several MovieClip objects having certain timeline animations) if I used the ImageClass initializer. Now I'm happy I was wrong :)
   
   Again, many thanks for pointing me to the right direction, Richard!

   By the way... how can I format the code blocks here on the forums so that my code can keep the indentation?

   To add code blocks as code, place the code inside <code> elements, and tick the "html" box beneath the comments box.
