   Hi, I'm very new to particle systems so please bear with me. I'm trying to expand the LogoTween example to Tween 3 images with bitmapdata objects (bitmapdata, bitmapdata2, bitmapdata3) particles. After 8 hours of working on this, when I run the code below I just get the first image that appears then disappears. Can anyone help with figuring out how to alter the LogoTween example to meet these needs? Thanks.

   function myImagesLoaded(e:Event):void
   {
   
   //Initialize
   /*emitter = new Emitter2D();
   particles = Particle2DUtils.createRectangleParticlesFromBitmapData(bitmapdata, 10, emitter.particleFactory,0, 0 );
   emitter.addExistingParticles( particles, false );
   var rect:Rectangle=bitmapdata.rect;
   renderer = new BitmapRenderer(rect,false);
   renderer.addFilter( new BlurFilter( 1, 1, 100 ) );
   renderer.addFilter( new ColorMatrixFilter( [ 1,0,0,0,0,0,1,0,0,0,0,0,1,0,0,0,0,0,0.99,0 ] ) );
   
   renderer.addEmitter( emitter );
   addChild( renderer );
   emitter.start();

   Oh, I forgot to remove the commenting marks from:
   /*tween1Emitter.addExistingParticles( particles, false );
   tween2Emitter.addExistingParticles( particles2, false );
   tween3Emitter.addExistingParticles( particles3, false );*/
   
   The results I got included this coding without the comment marks.
   
   Thanks.
