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

if (Input.GetMouseButtonDown(0))
{
    particles.Emit();
}

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() that was on this object and it works perfectly. That took 45 seconds.

using UnityEngine;

public class x : MonoBehaviour
{
    void Update()
    {
        if (Input.GetMouseButtonDown(0))
        {
            GetComponent<ParticleSystem>().Emit(1);
        }
    }
}
