错误 CS0246 使用枚举时找不到类型或命名空间名称

Question

单例脚本：

 public static ShipSingleton Instance { get { return _instance; } }


    private void Awake()
    {
        if (_instance != null && _instance != this)
        {
            Destroy(this.gameObject);
        }
        else
        {
            _instance = this;
            DontDestroyOnLoad(this.gameObject);
        }
    }

    public enum Ship
    {
        BasicShip
    };

    public Ship spawnShipID;

生成器对象

public GameObject basicShip;

void Start()
{
    if (ShipSingleton.Instance.spawnShipID == ShipSingleton.Ship.BasicShip)
    {
        Instantiate(basicShip, transform.position, Quaternion.identity);
    }
}

按钮脚本

 public Ship ShipID = ShipSingleton.Ship.BasicShip;

    public void shipchoice()
    {

        SceneManager.LoadScene("watcherqueen");
        ShipSingleton.Instance.spawnShipID = ShipID;

    }

不断收到此错误：

错误 CS0246 找不到类型或命名空间名称“Ship”（您是否缺少 using 指令或程序集引用？

我是否可能在按钮脚本中遗漏了对公共枚举的引用？

Answer 1

哦，我知道现在是什么问题了（我也会在另一个问题中解决它）--

此行需要引用ShipSingleton.Ship 而不仅仅是Ship：

public Ship ShipID = ShipSingleton.Ship.BasicShip;

所以它应该是这样的：

public ShipSingleton.Ship ShipID = ShipSingleton.Ship.BasicShip;

这是因为枚举类型Ship 是ShipSingleton 的成员。如果Ship 像这样在命名空间级别声明，则没有必要：

public enum Ship
{
    BasicShip
};

public class ShipSingleton
{
    public static ShipSingleton Instance { get { return _instance; } }


    private void Awake()
    {
        if (_instance != null && _instance != this)
        {
            Destroy(this.gameObject);
        }
        else
        {
            _instance = this;
            DontDestroyOnLoad(this.gameObject);
        }
    }

    Ship spawnShipID;
}
