Particle collision in Unity - Mini Project: Build & Apply

Particle collision

📖 Scenario: You are creating a simple Unity scene where particles move and collide with each other. You want to detect when two particles collide and print a message.

🎯 Goal: Build a Unity script that detects collisions between particles and prints a message when a collision happens.

📋 What You'll Learn

Create a Unity script with a ParticleCollision class

Add a OnParticleCollision method to detect collisions

Print a message when a collision occurs

💡 Why This Matters

🌍 Real World

Particle collision detection is used in games and simulations to create interactive effects like explosions, sparks, or damage.

💼 Career

Understanding particle collisions is important for game developers and simulation programmers to create realistic and engaging visual effects.

1

Create the ParticleCollision class

Create a public class called ParticleCollision that inherits from MonoBehaviour.

Unity

// Your code here

Need a hint?

Remember to include using UnityEngine; at the top.

2

Add the OnParticleCollision method

Inside the ParticleCollision class, add a public method called OnParticleCollision that takes a GameObject parameter named other.

Unity

using UnityEngine;

public class ParticleCollision : MonoBehaviour
{
    // Your code here
}

Need a hint?

This method is called automatically by Unity when a particle collides with another object.

3

Print a collision message

Inside the OnParticleCollision method, add a line to print the message "Particle collided with " followed by the other object's name using Debug.Log.

Unity

using UnityEngine;

public class ParticleCollision : MonoBehaviour
{
    void OnParticleCollision(GameObject other)
    {
        // Your code here
    }
}

Need a hint?

Use Debug.Log to print messages to the Unity Console.

4

Test the collision message output

Write a line to print "Particle collided with Enemy" to simulate the collision message output.

Unity

using UnityEngine;

public class ParticleCollision : MonoBehaviour
{
    void OnParticleCollision(GameObject other)
    {
        Debug.Log("Particle collided with " + other.name);
    }
}

// Your code here

Need a hint?

This simulates what Unity would print when a collision happens with an object named "Enemy".
