是否可以将 Unity GameObject 转换为 ScriptableObject class 类型？

Question

我已经创建了 scriptable object custom class Card:

[CreateAssetMenu(fileName = "Card", menuName = "Card")]
public class Card : ScriptableObject
{
    public new string name;
    public string Description;
    public Sprite HeroImage;
    public int Attack;
    public int Health;
    public int XCoord;
    public int YCoord;
}

我已经通过 Unity 编辑器添加了大量此类对象，并在 2d Canvas:

上实例化了 GameObjects 等对象

for (int i = 0; i < 5; i++)
{
    GameObject go = Instantiate(CardPrefabTemplate, new Vector3(x_delt, 0, 0), Quaternion.identity) as GameObject;
    go.transform.SetParent(MPlayerOpenedCards.transform, false);
    go.gameObject.name = "CardUIPrefabOpened" + i;
    x_delt += (int)(CardPrefabTemplBackgrRect.rect.width * CardPrefabTemplateBackground.localScale.x) + x_card_margin;
}

通过鼠标点击 Raycast 后我得到当前点击的卡片 GameObject:

GameObject RaycastOpenedCard(string prefabName)
{
    //Set up the new Pointer Event
    m_PointerEventData = new PointerEventData(m_EventSystem);
    //Set the Pointer Event Position to that of the mouse position
    m_PointerEventData.position = Input.mousePosition;
    //Create a list of Raycast Results
    List<RaycastResult> results = new List<RaycastResult>();
    //Raycast using the Graphics Raycaster and mouse click position
    m_Raycaster.Raycast(m_PointerEventData, results);

    if (Input.GetMouseButtonDown(0))
    {
        foreach (RaycastResult result in results)
        {
            if (result.gameObject.transform.parent != null && Regex.IsMatch(result.gameObject.transform.parent.name, prefabName))
            {
                Debug.Log("Hit " + result.gameObject.transform.parent.name);
                return result.gameObject.transform.parent.gameObject;
            }
        }
    }
    return null;
}

在程序的其他部分，我有 List<Card> ActiveCards 列表，但我无法 cast Raycasted GameObject 到 scriptableobject class 卡片:

GameObject g = RaycastOpenedCard("CardUIPrefabOpened");
if (g != null)
{
    if (ActiveCards != null && ActiveCards.Count < 5)
    {
        Mplayer.ActiveCards.Add(g.GetComponent<Card>());
    }
}

是否可以将 Unity GameObject 转换为 ScriptableObject class 类型？

错误：

ArgumentException: GetComponent requires that the requested component 'Card' derives from MonoBehaviour or Component or is an interface. UnityEngine.GameObject.GetComponent[T] () (at C:/buildslave/unity/build/Runtime/Export/Scripting/GameObject.bindings.cs:28) BoardManager.Update () (at Assets/Scripts/BoardManager.cs:202)

简单地说，不，不可能将 GameObject 转换为 ScriptableObject，在这方面也不可能相反。这是因为 GameObject 没有继承自 ScriptableObject，ScriptableObject 也没有继承自 GameObject。然而，它们都直接继承自 Object。

行 GameObject go = Instantiate(CardPrefabTemplate, new Vector3(x_delt, 0, 0), Quaternion.identity) as GameObject; 的原因是因为 Instantiate 将 Object 作为参数并克隆它，返回 Object。 ScriptableObject 是 Object，这样就可以了。您可以将 Object 转换为 GameObject 这样也可以。但这并没有取得太大的成就，因为你唯一要做的就是 Object 部分，所以在你的例子中，Object.name.

现在 GetComponent 失败的原因是因为它只能寻找 MonoBehaviour，而 ScriptableObject (Card) 不是。 MonoBehaviour 也继承自 Object 顺便说一句。

所以真正的问题是您最初想要实现的目标是什么？
