Unity OnCollision() not working

Question

Seem to have exhausted google looking for an answer to a VERY bullet simple code that should work.

void onCollisionEnter(Collision col) {
    print ("hit " + col.gameObject.name);
    Destroy (gameObject);
    }

Bullet object has the above script, SphereCollider (radius a lot bigger than object), RigidBody, not a trigger, not kinematic, is travelling slow. All checked during runtime.

When it hits a wall (Box collider), it just bounces off but no collisionEnter code is ran.

Debug console bubble is on.

Answer 1

While you are trying to call onCollisionEnter(), MonoBehaviour uses the function OnCollisionEnter().

The difference is quite enormous, on the technical side of things. Being a function, the first letter should be a capital. By being lower case, your creating an entirely different function, that does not overload the original collision function your trying to call from MonoBehaviour.

To clarify, we are not overloading a method from MonoBehaviour, in the traditional sense. You should not use the override keyword, as this will report "no suitable method found to override".
