I am new to Unity and I am trying to do a 2d board game. In the game there is a dice and when It is player’s turn he will click on the dice and dice will chose a random number between 1-7. The player will move according to dice. I am using these scripts;

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Dice : MonoBehaviour
{
    Rigidbody rb;

    bool hasLanded;
    bool thrown;

    Vector3 initPosition;

    public int diceValue;

    public DiceSide[] diceSides;

    public bool IsDoneRolling;
    // Assign game object through editor
    public GameObject gameControllerGameObject;
    private GameController gameController;


    // Start is called before the first frame update
    void Start()
    {
        rb = GetComponent<Rigidbody>();
        initPosition = transform.position;
        rb.useGravity = false;
    }
    void Awake()
    {
        gameController = gameControllerGameObject.GetComponent<GameController>();
    }

    // Update is called once per frame
    void Update()
    {
        if (rb.IsSleeping() && !hasLanded && thrown)
        {
            hasLanded = true;
            rb.useGravity = false;
            rb.isKinematic = true;

            SideValueCheck();

            gameControl.MovePlayer(diceValue);

        }
        else if (rb.IsSleeping() && hasLanded && diceValue == 0)
        {
            RollAgain();
        }
    }

    public void RollDice()
    {
        if (!thrown && !hasLanded)
        {
            IsDoneRolling = false;
            thrown = true;
            rb.useGravity = true;
            rb.AddTorque(Random.Range(0, 250), Random.Range(0, 250), Random.Range(0, 250));
        }
        else if (thrown && hasLanded)
        {
            Reset();
        }
    }

    void Reset()
    {
        transform.position = initPosition;
        thrown = false;
        hasLanded = false;
        rb.useGravity = false;
        rb.isKinematic = false;
        IsDoneRolling = true;
    }

    void RollAgain()
    {
        Reset();
        IsDoneRolling = false;
        thrown = true;
        rb.useGravity = true;
        rb.AddTorque(Random.Range(0, 250), Random.Range(0, 250), Random.Range(0, 250));
    }

    void SideValueCheck()
    {
        diceValue = 0;
        foreach (DiceSide side in diceSides)
        {
            if (side.OnGround())
            {
                diceValue = side.sideValue;
                Debug.Log(diceValue + " has been rolled!");
            }
        }
    }
}

public class PlayerPiece : MonoBehaviour

    public Route currentRoute;

    int routePosition;

    // Remove unnecessary variables
    public bool isMoving;

    // Update is called once per frame
    void Update()
    {

    }
    // Make this public so we can call it from GameControl
    // Add number of steps to move as parameter
    public IEnumerator Move(int steps)
    {
        if (isMoving)
        {
            yield break;
        }
        isMoving = true;

        while (steps > 0)
        {
            Debug.Log("Route position: " + routePosition);

            routePosition++;
            routePosition %= currentRoute.childNodeList.Count;

            Vector3 nextPos = currentRoute.childNodeList[routePosition].position;
            while (MoveToNextNode(nextPos)) { yield return null; }

            yield return new WaitForSeconds(0.1f);
            steps--;
        }

        isMoving = false;
    }

    bool MoveToNextNode(Vector3 goal)
    {
        return goal != (transform.position = Vector3.MoveTowards(transform.position, goal, 8f * Time.deltaTime));

    }
}

public class GameControl : MonoBehaviour
{
    // Be careful about using static variables when they're not necessary
    private GameObject player1, player2;
    // Add references to the player piece scripts
    private PlayerPiece player1Piece;
    private PlayerPiece player2Piece;

    private whosTurn;

    // Start is called before the first frame update
    void Awake()
    {
        player1 = GameObject.Find("Player1-Piece");
        player2 = GameObject.Find("Player2-Piece");

        // Set the reference to the script so you don't have to call GetComponent() each time
        player1Piece = player1.GetComponent<PlayerPiece>();
        player2Piece = player2.GetComponent<PlayerPiece>();
    }

    // Update is called once per frame
    void Update()
    {
        // Clean this out and we'll handle movement directly in the PlayerMove
    }
    // Change variable to handle steps to move
    public void MovePlayer(int steps)
    {
        switch (whosTurn)
        {
            case 1:
                StartCoroutine(player1Piece.Move(steps));
                break;

            case 2:
                StartCoroutine(player2Piece.Move(steps));
                break;
        }

        whosTurn *= -1;
    }
}

When I came back to Unity It says there is an error on GameControl.cs (the 3rd one) 13th line. Also the scripts Named Dice.cs , FollowThePath.cs , GameObject.cs respectively

I tried to move a pawn according to a dice. I was expecting when I click on dice it will give a random number and the pawn will move according to number. But all of them didnt happen. I just get some errors
