-  * Note: The ''**playerData**'' we created isn't the up-to-date one that lives on the server. We simply create our own copy of ''**PlayerData**'' client-side and update it as we receive packets. Since it's ''**public static**'' that means you can access it from anywhere on the client.+  * 注①：我们在客户端侧所创建的 ''**PlayerData**'' 并非与服务器侧实时同步。我们只是从服务器侧接收并在客户端侧创建了相应副本，并在客户端侧刷新。由于其关键字为 ''**public static**''，这意味着您可以在客户端的任意类中访问。
  
-  * Note: each time you restart the minecraft client with fabric, you're assigned a new UUID, so it may seem like it's not working, but that's just because of the developer environment. (If you run the fabric multiplayer server, 'Minecraft Server' and use authme, you could verify it does indeed work as it's supposed to.)+  * 注②：每次您使用 Fabric 调试启动客户端时，您所分配到的 UUID 都是不一样的，所以您可能会认为代码没有正确工作，但这只是因为您使用的开发环境使然。(如果您在生产环境运行一个 Minecraft 服务器并使用 Authme，您就可以确认模组在按照我们的预期目的工作了。)
