I have a cannon in my Player gameobject, I have a PlayerController.cs file in my Player object, the content is below. In addition, I have a Cannonball for my cannon object to throw. But when I use Instantiate prefab, I want spawned Item gonna use my player’s rotation, but it doesn’t, can you help me?

using UnityEngine;

public class PlayerMovement : MonoBehaviour
{
    [SerializeField]
    public GameObject CannonBall;
    [SerializeField]
    public GameObject player;
    [SerializeField]
    public GameObject FirePoint;
    [SerializeField]
    public GameObject BallsObject;

    // Camera Movement
    private float camSpeed;

    private float camAxisX;
    private float camAxisY;


    // Character Movement
    private float speed;

    private float minX;
    private float minZ;

    private float maxX;
    private float maxZ;

    private bool touched = false;

    private float horizontalInput;
    private float verticalInput;
    void Start()
    {
        StartGame();
    }
    private void Update()
    {

    }
    void FixedUpdate()
    {
        if (Input.GetButton("Fire1"))
        {
            FireCannon();
        }

        GetPlayerAxis();
        RotateChar();
        MoveChar();
    }
    void StartGame()
    {

        speed = 8f;
        camSpeed = 500f;
        Cursor.lockState = CursorLockMode.Locked;
        Cursor.visible = false;
    }
    void RotateChar()
    {
        player.transform.Rotate(Vector3.up * Time.deltaTime * camSpeed * camAxisX);
        player.transform.Rotate(Vector3.left * Time.deltaTime * camSpeed * camAxisY);
        player.gameObject.transform.localEulerAngles = new Vector3(player.gameObject.transform.localEulerAngles.x, player.gameObject.transform.localEulerAngles.y, 0);

    }
    void MoveChar()
    {
        if (!touched)
        {
            transform.Translate(Vector3.right * horizontalInput * speed * Time.deltaTime);
            transform.Translate(Vector3.forward * verticalInput * speed * Time.deltaTime);
        }
    }
    void GetPlayerAxis()
    {

        camAxisX = Input.GetAxis("Mouse X");
        camAxisY = Input.GetAxis("Mouse Y");
        horizontalInput = Input.GetAxis("Horizontal");
        verticalInput = Input.GetAxis("Vertical");
    }
    void FireCannon()
    {
        print(player.gameObject.transform.localRotation.eulerAngles);
        GameObject newBall = (GameObject)Instantiate(CannonBall, FirePoint.transform.position, Quaternion.Euler(player.gameObject.transform.localRotation.eulerAngles), BallsObject.transform);
        newBall.transform.localRotation = Quaternion.Euler(player.gameObject.transform.localRotation.eulerAngles);
    }
    private void OnCollisionEnter(Collision collision)
    {
        if(collision.gameObject.layer == 7)
        {
            name = collision.gameObject.name;
            if(name == "FrontBlock")
            {
                transform.Translate(Vector3.back * 0.2f);
            }
            if (name == "BackBlock")
            {
                transform.Translate(Vector3.forward * 0.2f);

            }
            if (name == "LeftBlock")
            {

                transform.Translate(Vector3.right * 0.2f);
            }
            if (name == "RightBlock")
            {

                transform.Translate(Vector3.left * 0.2f);
            }
            touched = true;
        }
    }
    private void OnCollisionExit(Collision collision)
    {
        if(collision.gameObject.layer == 7)
        {
            touched = false;
        }
    }
}

And I’m used for alternativly

    void FireCannon()
    {
        print(player.gameObject.transform.localRotation.eulerAngles);
        Instantiate(CannonBall, FirePoint.transform.position, player.transform.position);
    }
