How to stop Particle?

How to stop Particle? I used particle system do Explosion effects ！But you can not stop it.
When I use sio2EmitterStop () function, but Suspended particles.

In my demo,When Throw grenade,Hit and exploded , like sio2interactive's 3d shooter,How to stop Particle?

thank you!

You have to set particles lifetime to zero (0), based on some elapsed time (e.g. how long you want your emitter & particles to last basically).

Actually me the way I do it is when the emitter reach a certain amount of particle I stop creating them... then when all particles are done rendering I flush the emitter... that's the way I do it in BW.

That's right - I recall you mentioning it before as another way.
