Time scale independent Particle system in unity3d

ParticaleAnimator.cs

using UnityEngine;
using System.Collections;

public class ParticaleAnimator : MonoBehaviour {
  
	private void Awake()
	{
		particle = GetComponent<ParticleSystem>();
	}

	// Use this for initialization
	void Start ()
	{
		lastTime = Time.realtimeSinceStartup;
	}
	
	// Update is called once per frame
	void Update () 
	{
		
		float deltaTime = Time.realtimeSinceStartup - (float)lastTime;

        	particle.Simulate(deltaTime, true, false); //last must be false!!

        	lastTime = Time.realtimeSinceStartup;
	}

	private double lastTime;
	private ParticleSystem particle;

}

void Update ()
{
particle.Simulate(Time.unscaledDeltaTime, true, false)
}

when TimeScale set to 0 simulate not working in my project i don't know whats wong

Thanks, This help me much!!!

If you want to make it a bit more performance wise, You can add this code at the beginning of your Update():

if (Time.timeScale > 0.001f)
{
    return;
}

Helps when you have many ParticleSystem

Now you can use ParticleSystem.playbackspeed instead

Now, in Unity 2017 there is a Delta Time option which we can set to Unscaled.
