OnCollisionEnter not being called on collision

There are several similar threads out there

https://gamedev.stackexchange.com/questions/50770/unity-oncollisionenter-not-called

, however, I can't see why the OnCollisionEnter method is not being called.

I have a "Player" game component that must interact with an "Obstacle". In the inspector they look like:

Player:



Obstacle:



The scripts use by "Player" are:

PlayerMovement.cs:

Code (CSharp):

1. using UnityEngine;
2.  
3.  
4. public class PlayerMovement : MonoBehaviour
5. {
6.     public Rigidbody rigidBody;
7.     public float forwardForce = 2000f;
8.     public float sidewaysForce = 500f;
9.  
10.     // Start is called before the first frame update
11.     void Start()
12.     {
13.         // rigidBody.useGravity = false;  
14.         // rigidBody.AddForce(0, 2000, 500);
15.     }
16.  
17.     // Update is called once per frame
18.     void FixedUpdate()
19.     {
20.         // Add a forward force
21.         rigidBody.AddForce(0, 0, forwardForce * Time.deltaTime);
22.  
23.         if (Input.GetKey("d")) {
24.             rigidBody.AddForce(sidewaysForce * Time.deltaTime, 0, 0, ForceMode.VelocityChange);
25.         }
26.  
27.         if (Input.GetKey("a"))
28.         {
29.             rigidBody.AddForce(-sidewaysForce * Time.deltaTime, 0, 0, ForceMode.VelocityChange);
30.         }
31.  
32.     }
33. }
34.  

and PlayerCollision.cs:

Code (CSharp):

1. using UnityEngine;
2.  
3. public class PlayerCollision : MonoBehaviour
4. {
5.  
6.     public PlayerMovement movement;     // A reference to our PlayerMovement script
7.  
8.     // This function runs when we hit another object.
9.     // We get information about the collision and call it "collisionInfo".
10.     void OnCollisionEnter(Collision collisionInfo)
11.     {
12.         Debug.Log("Hit something");
13.         // We check if the object we collided with has a tag called "Obstacle".
14.         if (collisionInfo.collider.tag == "Obstacle")
15.         {
16.             movement.enabled = false;   // Disable the players movement.
17.             FindObjectOfType<GameManager>().EndGame();
18.         }
19.     }
20.  
21. }
22.  

Method OnCollisionEnter() is never called. Why?

GameManager is another component:



where GameManager.cs is:

Code (CSharp):

1. using UnityEngine;
2.  
3. public class GameManager : MonoBehaviour
4. {
5.     public void EndGame() {
6.         Debug.Log("GAME OVER MAN! GAME OVER!");
7.     }
8. }

What's wrong with the collision?

 

I forgot to tag the obstacles ... =)) . Fixed.
