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.");
}Practice Play and Check Effect
Call ps.Play();. Then if ps.isPlaying is true, print Debug.Log("Efekt calisiyor");.
Starter code
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();
// Oynat ve calisiyorsa ekrana mesaj yazdir
}
}Sample 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");
}
}
}Expected output
Efekt calisiyor
