public bool loop ;

Description

Is the Particle System looping?

If you disable looping on a playing Particle System, it will stop after the end of the current loop.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour { private ParticleSystem ps;

void Start() { ps = GetComponent<ParticleSystem>();

var main = ps.main; main.loop = true; } }
