    private Camera cam;
    [SerializeField]

    [SerializeField]
    private LayerMask mask;

    // Update is called once per frame
    void Update()
    {
        playerUI.UpdateText(string.Empty);
       // Create a ray at the center of the camera, shooting outwards
       Ray ray = new Ray(cam.transform.position, cam.transform.forward);
       Debug.DrawRay(ray.origin, ray.direction * distance);
       RaycastHit hitInfo; // Variable to store the collision information
       if (Physics.Raycast(ray, out hitInfo, distance, mask))
       {
            if (hitInfo.collider.GetComponent<Interactable>() != null)
            {
                playerUI.UpdateText(hitInfo.collider.GetComponent<Interactable>().promptMessage);
