Activate a particle system on click c# script

Hi,

I am actually new to Unity and i have a question.

I actually have a first person controller and a weapon attached to it.
I put a particle system on my scene (Unity Asset Store - The Best Assets for Game Making) and i would like to activate it when I press ‘fire’

This is my script (on my first person controller)

public Transform origin;
	public Object bullet;
	public ParticleSystem detonator;
	private float lastShoot = 0;
	
	// Update is called once per frame
	void Update ()
	{
		// pas de spamm de clic
		if (Input.GetButton ("Fire1") && Time.realtimeSinceStartup - lastShoot > (1.0/4.0)) {
			lastShoot = Time.realtimeSinceStartup;

			// animation
			detonator.enableEmission = true;
			detonator.Play();
		}
	}

Nothing appens, my particle system is not playing.

If you have any ideas…
Have a good weekend

Put you ParticleSytem Prefab in you Resource folder.
Then Load it into the Scene.
Then use Instantiate(). I’m using the Elementals Particle System myself: Unity Asset Store - The Best Assets for Game Making

Your case is simpler, since you only need to Instantiate the Particle System on the Weapon’s tip and parent it to the weapon: use particle.transform.parent = weapon.transform;

Here’s my code. It gets a bit more complicates here, as I make the splash as the cannons hit the water, but it’s useful if you want to add explosions to wherever the bullets hit.

public Object Splasher;

void Start()

{

Splasher = Resources.Load(“Splash”);
}

public void Make_a_Splash(GameObject canonball)
{

GameObject particle = GameObject.Instantiate(Splasher, canonball.transform.position, Quaternion.identity) as GameObject;

StartCoroutine(Cleanup_a_Blast(particle));

}

void Update()
{

    if(Input.GetKeyUp(KeyCode.Alpha1))
  ...Make_a_Splash(GameObject canonball)

//adds the splash to where the cannons hit.
//Cannons need to have a collider as a trigger attached.

}

public IEnumerator Cleanup_a_Blast(GameObject blast)
{
    yield return new WaitForSeconds(2);
    GameObject.Destroy(blast);
}
