Im wondering how to trigger a particle effect from a click in unity 2018.4

So im making a multiplayer fps and im wondering how to trigger a particle effect from a click in a script and im using unity 2018.4

 

That's about four or five questions all in one.

Break it apart:

- "from a click": any click? use Input.GetMouseButtonDown(0)

- "trigger a particle": do one of:

--- have the particle system and call .Emit() on it
--- instantiate a fresh copy of the particle system

- get it over the network: this is entirely dependent on your networking setup

And of course you need to decide where to position the particle system.

 

There is a red line under Emit()
This is my code

Code (CSharp):

1. if (Input.GetMouseButtonDown(0))
2. {
3.     particles.Emit();
4. }

 

You should already be on this page:

https://docs.unity3d.com/ScriptReference/ParticleSystem.Emit.html

Always start with the documentation.

 

I tried and it didnt work

 

Which part failed? Where did it get to? Only YOU can debug YOUR code.

To help gain more insight into your problem, I recommend liberally sprinkling Debug.Log() statements through your code to display information in realtime.

Doing this should help you answer these types of questions:

- is this code even running? which parts are running? how often does it run?
- what are the values of the variables involved? Are they initialized?

Knowing this information will help you reason about the behavior you are seeing.

I just created a particle system on a GameObject, wrote a script to call .Emit(1) on the GetComponent<ParticleSystem>() that was on this object and it works perfectly. That took 45 seconds.

Code (csharp):

1.  
2. using UnityEngine;
3.  
4. public class x : MonoBehaviour
5. {
6.     void Update()
7.     {
8.         if (Input.GetMouseButtonDown(0))
9.         {
10.             GetComponent<ParticleSystem>().Emit(1);
11.         }
12.     }
13. }
14.
