Collision recognition

Question

I am developing through tutorials the game Unity training day (Nightmares) and I realized that the player did not recognize collisions in objects.

When adding the "Capsule Collider" component, the error has been fixed, but the character moves alone. Where is the error?

`

using UnityEngine;

public class PlayerMovement : MonoBehaviour
{
    public float speed = 6f;

    Vector3 movement;
    Animator anim;
    Rigidbody playerRigidbody;
    int floorMask;
    float camRayLenght = 100f;

    void Awake ()
    {
        floorMask = LayerMask.GetMask ("Floor");
        anim = GetComponent <Animator> ();
        playerRigidbody = GetComponent <Rigidbody> ();

    }


    void Update ()
    {
        float h =Input.GetAxisRaw("Horizontal");
        float v =Input.GetAxisRaw("Vertical");

        Move (h,v);
        Turning ();
        Animating (h, v);

    }


    void Move (float h, float v)
    {

        movement.Set (h, 0f, v);

        movement = movement.normalized * speed * Time.deltaTime  ;

        playerRigidbody.MovePosition (transform.position + movement);

    }

    void Turning ()
    {

        Ray camRay = Camera.main.ScreenPointToRay (Input.mousePosition);

        RaycastHit floorHit;

        if(Physics.Raycast (camRay, out floorHit, camRayLenght, floorMask))
        {

            Vector3 playerToMouse = floorHit.point - transform.position;

            playerToMouse.y = 0f;

            Quaternion newRotation = Quaternion.LookRotation (playerToMouse);

            playerRigidbody.MoveRotation (newRotation);
        }




    }


    void Animating (float h,float v)
    {

        bool walking = h != 0f || v !=0f;

        anim.SetBool ("IsWalking", walking);
    }
}
