Particle System Summary
The Particle System is the foundation for visual effects (VFX) bringing game worlds to life. The main module sets lifetime (startLifetime), size (startSize), and rotation (startRotation); Emission controls spawning frequency, and Shape dictates emission bounds. The system is triggered from gameplay events via Play() and Stop().
ps.Play();
var em = ps.emission;
em.rateOverTime = 30f;Practice Manage Particle System
Call ps.Play();. Then print system status with Debug.Log("Aktif: " + ps.isPlaying); and Debug.Log("Hiz: " + ps.rate);.
Starter code
using System;
public class ParticleSystem
{
public bool isPlaying = false;
public float rate = 50f;
public void Play() { isPlaying = true; }
}
public static class Debug
{
public static void Log(object message) => Console.WriteLine(message);
}
public class Program
{
public static void Main()
{
ParticleSystem ps = new ParticleSystem();
// Sistemi baslat ve uretim hiziyla birlikte bilgileri yazdir
}
}Sample solution
using System;
public class ParticleSystem
{
public bool isPlaying = false;
public float rate = 50f;
public void Play() { isPlaying = true; }
}
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();
Debug.Log("Aktif: " + ps.isPlaying);
Debug.Log("Hiz: " + ps.rate);
}
}Expected output
Aktif: True Hiz: 50
Questions and answers
Review the lesson questions together with their answers. To test yourself, solve the lesson interactively.
1 Which module and shape are used to cause particles to scatter evenly in all directions as a sphere during an explosion?
- Color over Lifetime module - Gradient
- Renderer module - Billboard
- Emission module - Burst
- Shape module - Sphere Correct answer
Explanation: The module that governs emission geometry and direction is Shape, and the shape scattering in all directions is Sphere.
2 Summary Stop Particle
if (ps.isPlaying) ps.____();if (ps.isPlaying) ps.Stop();Explanation: To stop a running particle system, the Stop method is called.
