序列化到JSON？您可以使用JsonUtility完成此操作。
https://docs.unity3d.com/Manual/JSONSerialization.html

public class TestObject : ScriptableObject
{
    public string foo, bar;
}

var obj = ScriptableObject.CreateInstance<TestObject>();
obj.foo = "hello";
obj.bar = "world";
var json = JsonUtility.ToJson(obj);
Debug.Log(json); // {"foo":"hello","bar":"world"}

obj.foo = "something";
obj.bar = "else";
JsonUtility.FromJsonOverwrite(json, obj);
Debug.Log(obj.foo + ", " + obj.bar); // hello, world

据我所知，你不能，这是可能的，做一个自定义检查器，编辑器，图形用户界面，但它是相当棘手的，我不知道如何做到这一点，甚至。但也许，你可以做到这一点。

[System.serializable]
public class PlayerAttackCard
{
   public string AtackName,bookName;
   public bool multiTarget;
   public float Bacepower;
   public GameObject miniGame;
}

和可编写脚本的对象。

public class PlayerAttackCardData : ScriptableObject
{
    public PlayerAttackCard playerAttackCard = new PlayerAttackCard();
}

你应该能够使用它，你可以把它们放在一起或分开，我得到没有错误

[CreateAssetMenu(fileName = "item.asset",menuName = "inventory/item")][ System.Serializable]
public class Item:ScriptableObject

或

[CreateAssetMenu(fileName = "item.asset",menuName = "inventory/item"), System.Serializable]
public class Item:ScriptableObject
