OnCollisionEnter not being called despite objects colliding and moving

Questions & Answers
1

Still working on a 2D space shooter, and I can’t seem to register any OnCollisionEnters. The bullet is able to push enemies and bounce off walls, “is kinematic” is on only for walls, and all 3 elements have box/circle colliders and Rigidbody 2Ds (box for walls and circle for bullets and enemies).

Right now I’ve got

    void OnCollisionEnter(Collision collision)
    {
        Debug.Log("Bullet Collides");
        Destroy(gameObject);
    }

The Debug message doesn’t appear and the bullet prefab the script is attached to isn’t being destroyed.

You need to use
void OnCollisionEnter2D(Collision2D collision)
{
Debug.Log(“Bullet Collides”);
Destroy(gameObject);
}

OnCollisionEnter works only for 3D colliders and rigidbodies. For Rigidbody2D and 2D Colliders OnCollisionEnter2D is used
