unity particle doen't play second time

Question

I have a particle system defined in my game objects. When I call Play it plays (it plays for 5 seconds by design). when I call Play again nothing happens. I tried to call Stop and Clear before recalling Play but that didn't help.

Can particle systems play more than once?

My code is in this method, which is called when a button is clicked.

public void PlayEffect() 
{ 
    for (int i=0;i<3;i++) 
    { 
        NextItemEffectsP[i].Stop(); 
        NextItemEffectsP[i].Clear(); 
        NextItemEffectsP[i].Play(); 
    } 
}

NextItemEffectsP is an array that contains particles that I populate in the editor

I found the issue. The duration of the particle is 2 second. if I call play after 2 second nothing happen. Should I create new instance everytime I need to start a particle after the 2 second? how can I kn ow when the particle finish work so I can destroy it. — user2130415, May 04 '14 at 14:14

You should rework how your bullet works. Have some code on the bullet Prefab to control when it gets destroyed.

private float fuse = 1.0;
private float selfDestructTimer;

void Awake() {
    // Time.time will give you the current time.
    selfDestructTimer = Time.time + fuse;
}

void Update() {
    if (selfDestructTimer > 0.0 && selfDestructTimer < Time.time) {
        // gameObject refers to the current object
        Destroy(gameObject);
    }
}

Then with that control set up, you'll always just create new bullets whenever the fire button is pressed.
