Hiya, I've looked through the examples and can't find how to do this. I'm adding a TweenToZone: _startEmitter.addAction(new TweenToZone(new BitmapDataZone(__myBitmapData))); This works great ...

_startEmitter.addAction(new TweenToZone(new BitmapDataZone(__myBitmapData)));

This works great but I want my particles not to disappear when they reach their destination.

What's the best way to do this?

Thanks :)]]> How do I prevent particles fading once reached destination? http://flintparticles.org/forum/comments.php?DiscussionID=408&Focus=1402#Comment_1402 2010-10-09T16:16:32+01:00 2010-10-09T16:17:26+01:00 Richard http://flintparticles.org/forum/account.php?u=1

The tween is tied to the particle's lifetime. As a result, the particle dies when the tween ends. However, if you listen for the particle dead event, you can revive the particle and add it to a ...

However, if you listen for the particle dead event, you can revive the particle and add it to a different emitter which doesn't tween it (or kill it). Something like this

stableEmitter = new Emitter2D();
renderer.addEmitter( stableEmitter );
stableEmitter.start();

emitter.addEventListener( ParticleEvent.PARTICLE_DEAD, reviveParticle );

function reviveParticle( event:ParticleEvent ):void
{
  event.particle.revive();
  stableEmitter.addExistingParticles( [ event.particle ], false );
}

You can see a more complete example of this in the Logo Tween example.]]> How do I prevent particles fading once reached destination? http://flintparticles.org/forum/comments.php?DiscussionID=408&Focus=1464#Comment_1464 2010-12-09T21:15:40+00:00 2011-12-11T23:46:43+00:00 Bob vd Bibs http://flintparticles.org/forum/account.php?u=444

i tried this but the particle still has an alpha of 0 so i cant see it. (or something else is wrong).
Is there a way of getting more control over the lifecycle of the particle? How can i prevent the particle from fading?

Set the particle's color when you revive it. The color is a 32bit value, with the first 8 bits (the first FF below) indicating the alpha. stableEmitter = new Emitter2D(); renderer.addEmitter( ...

stableEmitter = new Emitter2D();
renderer.addEmitter( stableEmitter );
stableEmitter.start();

emitter.addEventListener( ParticleEvent.PARTICLE_DEAD, reviveParticle );

function reviveParticle( event:ParticleEvent ):void
{
  event.particle.revive();
  event.particle.color = 0xFFFFFFFF;
  stableEmitter.addExistingParticles( [ event.particle ], false );
}
