How to make OnCollisionEnter work without Rigitbody?

Question

Unity

Tipo OnCollisionEnter does not work, if there is no Rigitbody on some object, then it does not work.





Code on one of these objects

private void OnCollisionEnter(Collision collision)
    {
        Debug.Log("Gucci");
    }

Answer 1

Is there a need to not use Rigidbody on both bodies? I think in order to check whether the bodies collided one of them should be able to move, of course, no one bothers to move the body using Translate, for example. Rigidbody will not do anything bad, even if you do not want the bodies to be physical, the Rigidbody component has constraints in the inspector, you can limit the degrees of freedom there. And if you click all the checkboxes there, you get a completely non-physical body with a Rigidbody. So it doesn’t work without a Rigidbody, as I understand it, due to the fact that it is in it that the item responsible for detecting collisions is located.
