所以我正在開發一款跑酷游戲，它幾乎完成了。問題是我正在測試暫停面板，當玩家觸摸僵尸時，暫停面板出現，我通過按下重新啟動按鈕再次重新啟動游戲。但是當我再次觸摸僵尸面板時，面板沒有出現并給我標題中的錯誤。我被卡住了，任何幫助將不勝感激。這是代碼，我引用了錯誤發送給我的行：[SerializeField]private GameObject pausePanel;[SerializeField]private Button RestartGameButton;[SerializeField]private Text ScoreText;private int score;void Start (){    pausePanel.SetActive(false);    ScoreText.text = score + "M";    StartCoroutine(CountScore());}IEnumerator CountScore(){    yield return new WaitForSeconds(0.6f);    score++;    ScoreText.text = score + "M";    StartCoroutine(CountScore());}void OnEnable(){    PlayerDeath.endgame += PlayerDiedEndTheGame;}void OnDisable(){    PlayerDeath.endgame += PlayerDiedEndTheGame;}void PlayerDiedEndTheGame(){    if (!PlayerPrefs.HasKey("Score"))    {        PlayerPrefs.SetInt("Score", 0);    }    else    {        int highscore = PlayerPrefs.GetInt("Score");        if(highscore < score)        {            PlayerPrefs.SetInt("Score", score);        }    }    pausePanel.SetActive(true); //this is the line that error sends me but I cant figure it out because I didnt try to destroy the panel in the first place.    RestartGameButton.onClick.RemoveAllListeners();    RestartGameButton.onClick.AddListener(() => RestartGame());    Time.timeScale = 0f;}public void PauseButton(){    Time.timeScale = 0f;    pausePanel.SetActive(true);    RestartGameButton.onClick.RemoveAllListeners();    RestartGameButton.onClick.AddListener(() => ResumeGame());}public void GoToMenu(){    Time.timeScale = 1f;    SceneManager.LoadScene("MainMenu");}public void ResumeGame(){    Time.timeScale = 1f;    pausePanel.SetActive(false);}public void RestartGame(){    Time.timeScale = 1f;    SceneManager.LoadScene("Gameplay");}
