Question

我正在尝试序列化保存文件，但Json.net似乎无法序列化从Monobehaviour派生的类。它给我的错误如下

NotSupportedException：刚体属性已弃用

此项目中的任何地方都没有使用刚体，所以这个错误令我非常困惑。可能值得注意的是，我使用的是Json.net（3.5.8）的旧版本，因为这是支持项目框架（3.5）的最新版本

保存文件本身不是从Monobehaviour派生的，而是在其中的属性。这会导致错误出现。

这是我用来测试序列化的代码，如您所见，它应该序列化保存，打印出结果，对它进行脱序列化，然后再次打印出。

 var test1 = JsonConvert.SerializeObject(SaveManager.currentSave, Formatting.Indented, new JsonSerializerSettings()
            {
                PreserveReferencesHandling = PreserveReferencesHandling.Objects
            });

            Debug.Log(test1);

            var test2 = JsonConvert.DeserializeObject<Save>(test1);

            Debug.Log(test2);

Answer 1

您无法序列化MonoBehaviour或任何Unity组件。

此错误很可能是Json.net试图获取.rigidbody属性值引起的，并且不建议使用它，将抛出该错误。

因此，如果避免该错误，该过程仍然会失败。从您的“保存”中删除任何Monobehaviours，或创建一个新类以包含要保存的数据。

Json.net无法序列化从Monobehaviour派生的类
