4.5 Collision Detection

Collisions allow objects to interact with one another. Let’s implement a simple collision detection system.

Step 1: Create a Collision Script
Attach the following script to your player object:

void OnCollisionEnter(Collision collision) {
    Debug.Log("Collided with: " + collision.gameObject.name);
}

Explanation:

• OnCollisionEnter: Triggered when the object collides with another object.
• collision.gameObject.name: Logs the name of the object it collided with.

Step 2: Test It

1. Add another object (e.g., a wall) to your scene.
2. Ensure both objects have Colliders.
3. Press Play and observe the Console when the player collides with the object.
