gives Script error: OnCollisionEnter
This message parameter has to be of type:
The message will be ignored.
why?

Answer 1

OnCollisionEnter there is a collision parameter, not a collider. Collisions don't have tags or anything.

oid OnCollisionEnter(Collision bullet)
    {
        if (bullet.(ТУТ УЗНАТЬ КОЛЛАЙДЕР ИЗ КОЛЛИЗИИ).CompareTag("Ring"))
        {
            r = true;
            Debug.Log("R");
        }

and further by analogy. Collision - in fact, just infa about intersection points.
