Changing ParticleSystem attributes at runtime

Hello FeastSC2

I believe you can do that. Check out the documentations example here

 using UnityEngine;
 using System.Collections;
 
 public class ExampleClass : MonoBehaviour
 {
     private ParticleSystem ps;
     public float hSliderValue = 1.0F;
 
     void Start()
     {
         ps = GetComponent<ParticleSystem>();
     }
 
     void Update()
     {
         var main = ps.main;
         main.startLifetime = hSliderValue;
     }
 
     void OnGUI()
     {
         hSliderValue = GUI.HorizontalSlider(new Rect(25, 45, 100, 30), hSliderValue, 0.0F, 5.0F);
     }
 }
