   Hi!
   I was wondering how to use the particleSystem properly.

   Right now i am creating a particlesystem on init, but i have to inmediately call stopsystem because it starts playing...

   Then when i have to make the particles appear i have to set the emission rate and call resetsystem...

   Also... i doesn't ever stop, how can i set a time for it? or do i have to start a timer and stop the system with that?

   What i am trying to archieve is... the player touches something and a particlesystem runs for a while, but the player could be touching a couple of things, so there would be at least 3 particlesystems running at a given time.

   How could i make all of them stop after (and be removed) after some seconds?

   Thanks!

   Particle Designer by 71squared ( http://particledesigner.71squared.com/ ) has full Cocos2D support. You can edit your effects and then export a Cocos2D friendly .plist file. You just need to add this file to your project and you can use it like all other Nodes:

   CCQuadParticleSystem *particle = [CCQuadParticleSystem particleWithFile:@"MyParticleFile.plist"];
   particle.position = cpp(160,240);
   [self addChild:particle];

   The price for Particle Designer is $7.99. I am using this tool and I am very happy whit it.

   P.S.:

   If you want to Stop a particle you can add it with a tag and then remove it by tag:

   ...

   enum particle_tags {
   kParticle1 = 1,
   kParticle2 = 2,
   kParticle3 = 3
   };
   ...

   Start with:
   [self addChild:particle z:10 kParticle1];

   Stop with:
   [self removeChildByTag:kParticle1 cleanup:YES];

   Also take a look at "CCDelayTime" action and "CCSequence"
