Hey all!
So I have been after this for an hour now and I’ve tried using the Unity API but for some reason that doesn’t work. Just trying to get my particle system to turn on when an enemy enters my trigger.

using UnityEngine;
using System.Collections;

public class Turret2ai : MonoBehaviour
{
public float rotSpeed;
public float spawnWait;
public bool doneWaiting;
public ParticleSystem fire;

// Use this for initialization
void Start()
{
    doneWaiting = true;
    //myRigidbody = gameObject.AddComponent<Rigidbody>();
    // myRigidbody.constraints = RigidbodyConstraints.FreezePosition;
}

// Update is called once per frame
void Update()
{
}
void OnTriggerStay(Collider other)
{
    if (other.gameObject.tag == "Enemy")
    {
        Quaternion rotation = Quaternion.LookRotation(other.transform.position - transform.position);
        transform.rotation = Quaternion.Slerp(transform.rotation, rotation, Time.deltaTime * rotSpeed);
        fire.emission.enabled = true;
        if (doneWaiting)
        {
            StartCoroutine(Shooting());
            other.GetComponent<EnemyHealth>().currentHealth -= 4;
        }
    }
    else
    {
        fire.emission.enabled = false;
    }
    }
IEnumerator Shooting()
{
    doneWaiting = false;
    yield return new WaitForSeconds(spawnWait);
    doneWaiting = true;
}

}

(i have also tried doing the var em = fire.emission;
em.enabled = true; with no results)

You can use Emit() to directly emit a certain number of particles or Play() to play the particle effect (once if looping is set to false).

Let me know if this works and if not what kind of error you’re getting.
