我已将 Unity 更新到 2017.4.0f1，并且我有关于保存一些信息的脚本 在类似文本的文件中。我用过
public static string savePath = Application.persistentDataPath + "/";
但我收到此错误
get_persistentDataPath is not allowed to be called from a MonoBehaviour constructor (or instance field initializer), call it in Awake or Start instead. Called from MonoBehaviour 'FileHandler' on game object 'DisplayHigh'.
See "Script Serialization" page in the Unity Manual for further details.

我真的很困惑和沮丧，你知道吗。
如有任何帮助，我们将不胜感激。
最佳答案
public static string savePath;
