Play and Stop

Learn to control particles with particleSystem.Play and Stop.

Playback Control with Play and Stop

Particle systems are controlled from C# code using the Play() and Stop() methods. When a character jumps, you call ps.Play() to emit dust, and when shooting stops, you call ps.Stop() to halt muzzle smoke.

ParticleSystem ps = GetComponent<ParticleSystem>();
ps.Play();
// ps.Stop();

isPlaying and State Checks

To determine if a particle system is actively running, check the ps.isPlaying boolean property. Additionally, when calling Stop(), behavior parameters let you decide whether existing particles disappear immediately or finish their lifespan.

if (ps.isPlaying)
{
    Debug.Log("Effect is currently playing.");
}

Exercise Play and Check Effect

Call ps.Play();. Then if ps.isPlaying is true, print Debug.Log("Efekt calisiyor");.

Show example solution

using System;

public class ParticleSystem
{
    public bool isPlaying = false;
    public void Play() { isPlaying = true; }
    public void Stop() { isPlaying = false; }
}

public static class Debug
{
    public static void Log(object message) => Console.WriteLine(message);
}

public class Program
{
    public static void Main()
    {
        ParticleSystem ps = new ParticleSystem();
        ps.Play();
        if (ps.isPlaying)
        {
            Debug.Log("Efekt calisiyor");
        }
    }
}
