I've been playing around with this all morning and it seems great, but I'm a little confused - I'm trying to implement a glitter-type effect, and it's getting there, but I can't work out how to Age or restart the process. I've added in the Age below and it just stops everything - what is it I'm missing here...? Also, what's the simplest way to continually generate particles from the original source?

emitter = new Emitter2D();
particles = Particle2DUtils.createPixelParticlesFromBitmapData( bmd, emitter.particleFactory, 50, 75);
emitter.addExistingParticles( particles, false );

emitter.counter = new Steady( 250 );

var renderer:PixelRenderer = new PixelRenderer(new Rectangle( 0, 0, 500, 255 ));
renderer.addEmitter( emitter );
addChild( renderer );

emitter.counter = new Steady(250);

emitter.addInitializer( new Lifetime( 1 ) );
emitter.addAction(new Age());
emitter.addAction (new Accelerate( 0, 0));
emitter.addAction( new RandomDrift( 40, 40 ) );
emitter.addAction( new Move() );
emitter.addAction(new Fade());


emitter.start();

Thanks for your help, and sorry for being stupid!

The lifetime initializer isn't being applied to the particles, because you're adding it after you've added the particles to the emitter. Try this. emitter = new ...

emitter = new Emitter2D();
emitter.addInitializer( new Lifetime( 1 ) ); // add the initializer
particles = Particle2DUtils.createPixelParticlesFromBitmapData( bmd, emitter.particleFactory, 50, 75);
emitter.addExistingParticles( particles, true ); // true causes it to apply the initializer to the particles

var renderer:PixelRenderer = new PixelRenderer(new Rectangle( 0, 0, 500, 255 ));
renderer.addEmitter( emitter );
addChild( renderer );

emitter.addAction(new Age());
emitter.addAction( new RandomDrift( 40, 40 ) );
emitter.addAction( new Move() );
emitter.addAction(new Fade());

emitter.start();]]> http://flintparticles.org/forum/comments.php?DiscussionID=204&Focus=776#Comment_776 2009-04-20T22:58:12+01:00 2010-12-26T16:08:31+00:00 BillyT http://flintparticles.org/forum/account.php?u=189

Thank you, that's really useful. Thanks for a great system, and thanks for the quick response!
