Summary - Particle System

Reinforce Particle System usage with a summary task.

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;

Exercise Manage Particle System

Call ps.Play();. Then print system status with Debug.Log("Aktif: " + ps.isPlaying); and Debug.Log("Hiz: " + ps.rate);.

Show example 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);
    }
}

Test yourself

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
Show answer

Shape module - Sphere — The module that governs emission geometry and direction is Shape, and the shape scattering in all directions is Sphere.

Summary Stop Particle

if (ps.isPlaying) ps.____();

Show answer

if (ps.isPlaying) ps.Stop();
