(3d) Destroy a GameObject when player walks over it

Hey im new to Unity and C#.
I will ask if there are anybody who know how i can Destroy a GameObject when my player walk over it or stand on it?

Create collider on both objects. If you want collision with this object add OnCollisionEnter to detection object and inside method destroy player GameObject, look here: Unity - Scripting API: Collider.OnCollisionEnter(Collision)
But if you want to create invisible trigger GameObject, just tick IsTrigger property in RigidBody and then implement method OnTriggerEnter and inside it destroy GameObject , look here: Unity - Scripting API: Collider.OnTriggerEnter(Collider)
