   Hello, I am trying to display 2 shapes from the library using InitializerGroup. I can only see 1 at the time... don't know what I am doing wrong :(
   
   var AppleInitializer:InitializerGroup = new InitializerGroup();
   AppleInitializer.addInitializer( new SharedImage( new Apple()));
   AppleInitializer.addInitializer( new ScaleImageInit(0.1, 0.3));
   AppleInitializer.addInitializer( new Position( new RectangleZone( 0, 0, 1000, 500)));
   
   var MickeyInitializer:InitializerGroup = new InitializerGroup();
   MickeyInitializer.addInitializer( new SharedImage ( new Mickey()));
   MickeyInitializer.addInitializer( new ScaleImageInit(0.1, 0.3));
   MickeyInitializer.addInitializer( new Position( new RectangleZone( 0, 0, 1000, 500)));
   
   emitter = new Emitter2D();
   emitter.counter = new Blast(1);
   renderer = new BitmapRenderer( new Rectangle ( 0, 0, 1000, 500));
   emitter.addInitializer( new ChooseInitializer ( ([MickeyInitializer, AppleInitializer])) );
   addChild(renderer);
   renderer.addEmitter(emitter);
   emitter.addInitializer( new Velocity ( new DiscZone (new Point (25, 25), 100)));
   
   emitter.addAction( new WrapAroundBox(-100, -100, 1100, 700));
   emitter.addAction( new Move());
   emitter.start();
   
   it does work if I use: emitter.counter = new Steady(1);
   Thx for your help.

   Your counter, Blast(1), indicates you only want one particle. If you want to see both shapes you'll need to create more particles. e.g.
   
   emitter.counter = new Blast( 100 );

   Hey Richard,
   Thanks for your help.
   I guess I am not sure how to program what I am trying to do:
   I don't want 100 particles. I have 5 different shapes that I pulled from the library and I want to show only those 5 objects and use Flint to create interaction between them (like MutualGravity, Approach Neighbours etc ) ... Should I use 5 emitters?
   Thanks again.

   You could create a custom initializer to set the particles' images to each of the five shapes, and set the counter to a blast with a count of 5.
   
   Or, create instances of the five shapes and use the createParticles2DFromDisplayObjects method to create particles from them.

   Hey Richard,
   Thanks a lot for your help. I managed to make it work :)
   I had to add an EventListener on "particleAdded" to start the emitter. If not, I get this error:
   
   TypeError: Error #2007: Parameter child must be non-null.
   at flash.display::DisplayObjectContainer/addChildAt()
   at org.flintparticles.twoD.renderers::DisplayObjectRenderer/addParticle()[/actionScript/org/flintparticles/twoD/renderers/DisplayObjectRenderer.as:97]
   at org.flintparticles.common.renderers::SpriteRendererBase/particleAdded()[/actionScript/org/flintparticles/common/renderers/SpriteRendererBase.as:151]

   at org.flintparticles.common.emitters::Emitter/start()[/actionScript/org/flintparticles/common/emitters/Emitter.as:831]
   
   So, here is the code:
   
   public function CreateParticles()
   {
   emitter = new Emitter2D();
   var renderer:DisplayObjectRenderer = new DisplayObjectRenderer ();
   addChild(renderer);
   renderer.addEmitter(emitter);
   
   ////// These are assets in a swc file:
   var myApple:Apple = new Apple();
   var myMickey:Mickey = new Mickey();
   var myCoca_cola:Coca_cola = new Coca_cola();
   var myMac_Donalds:Mac_Donalds = new Mac_Donalds();
   var myMarlboro:Marlboro = new Marlboro();
   var myNike:Nike = new Nike();
   
   var myArray:Array = [myApple, myMickey, myCoca_cola, myMac_Donalds, myMarlboro, myNike];
   
   emitter.addInitializer( new Position( new RectangleZone( 0, 0, 1000, 500)));
   emitter.addInitializer( new Velocity ( new DiscZone (new Point (25, 25), 10)));
   emitter.addInitializer( new ScaleImageInit( 0.1, 0.2 ));
   emitter.addAction( new WrapAroundBox(-100, -100, 1100, 600));
   emitter.addAction( new Move());
   emitter.addAction( new ApproachNeighbours(500, 10));
   
   var myParticles:Vector.<Particle> = Particle2DUtils.createParticles2DFromDisplayObjects( myArray );
   
   emitter.addEventListener("particleAdded", particleHandler);
   emitter.addParticles( myParticles , true);
   emitter.counter = new Blast(6);
   //////// This creates an error >>> emitter.start();
   }
   
   protected function particleHandler(event:ParticleEvent):void
   {
   emitter.start();
   }

   Try removing the blast counter. You don't want to create more particles, you've already created the six particle you need with this code
   
   var myParticles:Vector.<Particle> = Particle2DUtils.createParticles2DFromDisplayObjects( myArray );
emitter.addParticles( myParticles , true);
   
   That should remove the error.
