How to play particle system only one time ?

Question

Hi there, I'm trying to play a particle system only ONE time, so here is my code:

 public ParticleEmitter fireWork;
 void Update() {
     // my stuffs
     if (distance < 0.3f) {
          // my other stuffs
          Instantiate(fireWork, particlePosition, Quaternion.identity);
          fireWork.Emit();
     }
 }

But it not works, the particle's still repeat times to times. Can anyone help me ?

http://docs.unity3d.com/ScriptReference/ParticleEmitter.Emit.html

Makes the emitter spit out a random number of particles, as set by the minEmission and maxEmission properties.

So every time Update is called, and distance is < 0.3f you'll get N particles emitted where minEmission < N < maxEmission

thanks for your help. But what I want is call the fully particles just 1 time. I've tried the $$anonymous$$, max emission but it isn't the solution in my situation, the particle system still called many times.

Don't know if I can answer here and now, but after Instatiating your gameobject you have to destroy it, especially for particles.

So just do Destroy(ParticleGameobject, n) with n is the duration you want for the Particle.
