我的C#中有一个相当模糊的问题（Unity）代码。它在于这样一个事实，即我的球员消失，因为关于spawnpoint的规定行。因为他们，我的球员简单地消失，当我运行游戏可能的问题行是22，109 - 112.请帮助我解决这个问题。提前非常感谢但是我需要spawnpoint来做进一步的工作。提前非常感谢!

        if(pesos >= weaponPrices[weapon.weaponLevel])
        {
            pesos -= weaponPrices[weapon.weaponLevel];
            weapon.UpgradeWeapon();

        return false;
    }

        float ratio = (float)player.hitpoint / (float)player.maxHitpoint;
        hitpointBar.localScale = new Vector3(1, ratio, 1);
    }

    }

    public void Respawn()

        UnityEngine.SceneManagement.SceneManager.LoadScene("SampleScene");

    }

    public void SaveState()

        s += experience.ToString() + "|";
        s += weapon.weaponLevel.ToString();
    }

    public void LoadState(Scene s, LoadSceneMode mode)
    {
        SceneManager.sceneLoaded += LoadState;
        if (!PlayerPrefs.HasKey("SaveState"))
            return;

        string[] data = PlayerPrefs.GetString("SaveState").Split('|');

        pesos = int.Parse(data[1]);
        experience = int.Parse(data[2]);
        player.SetLevel(GetCurrentLevel());
        weapon.SetWeaponLevel(int.Parse(data[0]));
    }
}

在一个月的时间里，我试了很多方法，但没有一个能解决这个问题。
