如何在Unity场景中激活暂停菜单窗口时锁定我的相机视图？

using UnityEngine;

public class PauseMenu : MonoBehaviour
{
    public GameObject pauseMenu;
    public Camera mainCamera;

    private bool isPaused = false;

    private void Update()
    {
        if (Input.GetKeyDown(KeyCode.Escape))
        {
            isPaused = !isPaused;
            pauseMenu.SetActive(isPaused);

            if (isPaused)
            {
                LockCameraView();
            }
            else
            {
                UnlockCameraView();
            }
        }
    }

    private void LockCameraView()
    {
        mainCamera.GetComponent<CameraController>().enabled = false;
        Cursor.lockState = CursorLockMode.None;
        Cursor.visible = true;
    }

    private void UnlockCameraView()
    {
        mainCamera.GetComponent<CameraController>().enabled = true;
        Cursor.lockState = CursorLockMode.Locked;
        Cursor.visible = false;
    }
}
