【问题描述】：
大家好，我是 Unity 和 C# 的新手。 我有这个脚本来创建/登录用户并在 firebase 数据库中发布（使用电子邮件和密码）。 我从 youtube 教程中复制了它，做了一些修改

我的问题是我无法在场景之间保存我的 firebase 登录信息，当我更改场景时，我无法再与我的 firebase 数据库进行交互。 我尝试制作一个 dontdestroyonload 脚本并添加一个统一游戏对象，其中包含我的 PlayerScore 脚本，但没有奏效。
我读到我需要将我的用户 ID 存储在一个静态变量中以便从任何地方调用它，但我不知道如何，因为我对 c# 编码非常陌生
有人可以指导一下吗，谢谢。 PS：上面的脚本需要另外 3 个脚本才能工作，其中存储/获取一些值。 如果有必要，我会添加它们。
