“GameObject”类型的对象已被销毁，但您仍在尝试访问它

Question

所以我正在开发一款跑酷游戏，它几乎完成了。问题是我正在测试暂停面板，当玩家触摸僵尸时，暂停面板出现，我通过按下重新启动按钮再次重新启动游戏。但是当我再次触摸僵尸面板时，面板没有出现并给我标题中的错误。我被卡住了，任何帮助将不胜感激。这是代码，我引用了错误发送给我的行：

[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");

}

我找到了解决方案。这是 OnDisable 方法的一个简单错误。我删除了 += 符号并用 -= 符号更改了它，因为它在应该禁用时启用了该事件。
