示例解析

GlobalFileLock 是一种非常简单的避免文件冲突的方法，专为此示例设计。
- 独立文件操作不会导致任何问题。
- 每个文件操作都需要许多步骤和多个 API 调用，因此请勿尝试以多种方式同时访问同一文件。
- 如果你非常小心，可能不需要任何锁定机制。
- 如果需要进行一些复杂工作，锁定机制可能要复杂得多。
OnGUI 是完全在脚本中构建 Unity GUI 的一种非常古老(但非常密集)的方法。
- 你的 GUI 将更好，并且与游戏密切相关。
所有 PlayFab 功能都需要先登录或进行身份验证。
LoadAllFiles() 的功能正如其名。对于当前登录的实体，将加载保存到 PlayFab 的所有文件。
- 这需要多个步骤：
  - 询问 PlayFab 文件所在的位置，
  - 然后分别下载它们。
UploadFile(string fileName) 将文件保存到实体的服务中。
- 为简单起见，此示例一次保存一个文件，但也可以原子方式成批上传文件。
- 步骤为：
  - 初始化原子上传操作，
  - 上传所有文件，
  - 完成原子上传操作。
- 在原子上传操作成功完成之前，实体不会认为文件上传完成，也不会向其他调用者反映任何更改。

Game Manager 和实体

Game Manager 允许你操作玩家的对象和文件。已更新玩家概述，以显示游戏玩家和主玩家帐户信息。

此外，现在文件和对象在 Players 选项卡中有自己的部分。
