Collision Detection does not work in my scene

Questions & Answers

Hello all,
I am trying to setup collision detection in my scene but it can never seem to work.
Right now, I am controlling a Character object using FirstPerson. I attached a SphereCollider to the object and attatched a BoxCollider to the object it needs to collide with.
When I test it however, it just walks through it.
I then attached this Script to the FirstPerson object:

public class Collisions : MonoBehavior {
    void OnCollisionEnter(Collision c) {
        Debug.Log("Collide");
    }
}

But nothing happens when it should be colliding.

I have now tried attaching a rigid body to the Sphere, and still do not get any response.

Is there anything else I should try?

Thanks.

I realize this checklist may sound dumb or laborious, but it’s important to get it out of the way:

  • Make sure that both objects have colliders attached.
  • Make sure that at least one object has a non-kinematic rigidbody attached.
  • Make sure that at least one object has a script which responds to collisions (like your Collisions script).
  • If you’ve customized your physics settings, make sure that both objects are on layers which should be colliding.
