c# - Unity 5 游戏对象序列化

Question

我正在尝试使用 Newtonsoft.Json 序列化整个 GameObject。 当我使用 JsonConvert 序列化对象时，它会抛出错误:

    NotSupportedException: rigidbody property has been deprecated
    UnityEngine.GameObject.get_rigidbody () (at C:/buildslave/unity/build/Runtime/Export/UnityEngineGameObject_Deprecated.cs:23)
(wrapper dynamic-method) UnityEngine.GameObject.Getrigidbody (object) <IL 0x00006, 0x00073>
Newtonsoft.Json.Serialization.DynamicValueProvider.GetValue (object) (at Assets/JsonDotNet/Source/Serialization/DynamicValueProvider.cs:104)
Rethrow as JsonSerializationException: Error getting value from 'rigidbody' on 'UnityEngine.GameObject'.
Newtonsoft.Json.Serialization.DynamicValueProvider.GetValue (System.Object target) (at Assets/JsonDotNet/Source/Serialization/DynamicValueProvider.cs:108)
Newtonsoft.Json.Serialization.JsonSerializerInternalWriter.SerializeObject (Newtonsoft.Json.JsonWriter writer, System.Object value, Newtonsoft.Json.Serialization.JsonObjectContract contract, Newtonsoft.Json.Serialization.JsonProperty member, Newtonsoft.Json.Serialization.JsonContract collectionValueContract) (at Assets/JsonDotNet/Source/Serialization/JsonSerializerInternalWriter.cs:338)

为什么会发生这种情况？

这里有问题:

public object GetValue(object target)
    {
      try
      {
        if (_getter == null)
          _getter = DynamicReflectionDelegateFactory.Instance.CreateGet<object>(_memberInfo);

        return _getter(target);
      }
      catch (Exception ex)
      {
        throw new JsonSerializationException("Error getting value from '{0}' on '{1}'.".FormatWith(CultureInfo.InvariantCulture, _memberInfo.Name, target.GetType()), ex);
      }
    }

它是 DynamicValueProvider.cs 的一部分

我不了解Newtonsoft.Json，但从错误消息来看 - GameObject property rigidbody已在 Unity 5 中与其他一些常见属性 getter 一起被弃用，请参阅 here和 here 。

所有调用rigidbody的电话必须替换为 GetComponent<Rigidbody>()相反。
