Trying to start/stop all particlesystems in a game object

I am trying to get all particle systems in a game object and start/stop them at the same time. Rather than listing each system individual I was hoping to get them all in an array, but it isn't working.

Code (CSharp):

1. using UnityEngine;
2.  
3. public class FireEffects_OnOff : MonoBehaviour {
4.     public GameObject R_Hand_Effects;
5.  
6.     public void R_Hand_Effects_On() {
7.         Component[] emiters;
8.         emiters = R_Hand_Effects.GetComponents(typeof(ParticleSystem));
9.         foreach (ParticleSystem p_system in emiters) {
10.             p_system.Play();
11.             }
12.         }
13.  
14.     public void R_Hand_Effects_Off() {
15.         Component[] emiters;
16.         emiters = R_Hand_Effects.GetComponents(typeof(ParticleSystem));
17.         foreach (ParticleSystem p_system in emiters) {
18.             p_system.Stop();
19.             }
20.         }
21.     }

 

I'm guessing your particle systems are children? GetComponents only searches one GameObject.

You want GetComponentsInChildren: https://docs.unity3d.com/ScriptReference/GameObject.GetComponentsInChildren.html

There may also be issues with your casting. Try:

Code (csharp):

1.  
2. ParticleSystem[] particleSystems = GetComponentsInChildren<ParticleSystem>();
3.  

rather than Component[].

 

Yup!

Code (CSharp):

1. public void R_Hand_Effects_Off() {
2.         ParticleSystem[] particleSystems = R_Hand_Effects.GetComponentsInChildren<ParticleSystem>();
3.         foreach (ParticleSystem p_system in particleSystems) {
4.             ParticleSystem.EmissionModule em = p_system.GetComponent<ParticleSystem>().emission;
5.             em.enabled = false;
6.             }
7.         }
