当我在没有数据的情况下进入游戏时，即使我没有任何进展，它也会打印“玩家的数据已连接”。当我带着进度离开时，没有任何打印表明我的数据尚未保存。我加入后就什么都没有了。我读过 10 篇不同的帖子，但没有一个对我有帮助。请有人帮忙！

假设您在工作室，您是否启用了工作室测试的 API 访问权限？ 如果没有，您将无法访问实际发布的游戏使用的数据存储。

当我阅读我们的脚本时，我发现您使用了带有两个参数的 GetAsync，而只有一个参数。这很可能不会在玩家第一次加入时造成问题，因为它将返回 nil，但玩家第二次加入时，因为此时已填充，可能会导致随机的不需要的行为。

我建议您还将玩家的用户 ID 分配给本地变量，因为当脚本仍在运行时，玩家将被取消引用并返回 nil，这很可能会导致您的问题。
