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（与电子邮件和密码）.我从youtube教程中复制了它，并做了一点修改。

我的问题是我不能在场景之间保存我的firebase登录名，当我改变场景时，我不能再与我的firebase数据库进行交互.我试着做了一个dontdestroyonload脚本，并添加了一个包含我的PlayerScore脚本的unity gameobject，但没有成功。
我读到的是需要将我的userid存储在一个静态变量中，以便在任何地方调用它，但我不知道怎么做，因为我是c#编码的新手。
Can someone give some guidance?, thanks.PS: the script of above need another 3 script to works, where storeget some values.If is necessary I add them.
Firebase SDK会自动持久化认证状态，并尝试自动恢复它。你只需要写代码来拾取它，这涉及到附加一个监听器到auth状态。
请看Firebase文档中的第一个片段，内容为 获取当前登录的用户:
建议通过在Auth对象上设置一个监听器来获取当前用户。
Firebase.Auth.FirebaseAuth auth; Firebase.Auth.FirebaseUser user; // Handle initialization of the necessary firebase modules: void InitializeFirebase() { Debug.Log("Setting up Firebase Auth"); auth = Firebase.Auth.FirebaseAuth.DefaultInstance; auth.StateChanged += AuthStateChanged; AuthStateChanged(this, null); } // Track state changes of the auth object. void AuthStateChanged(object sender, System.EventArgs eventArgs) { if (auth.CurrentUser != user) { bool signedIn = user != auth.CurrentUser && auth.CurrentUser != null; if (!signedIn && user != null) { Debug.Log("Signed out " + user.UserId); } user = auth.CurrentUser; if (signedIn) { Debug.Log("Signed in " + user.UserId); } } } void OnDestroy() { auth.StateChanged -= AuthStateChanged; auth = null; }
我想，这里可能有些混乱，因为我看到了一个对Auth对象的引用。官方Firebase Unity SDK 与原始REST调用混合在一起的 RestClient. 我会回答这个问题，假设你可以使用的是 Unity SDK. 这比试图手动使用Firebase SDK要简单得多（并且可以得到很好的好处--比如本地缓存）。
1) Firebase认证
一旦Firebase认证被初始化。FirebaseAuth.DefaultInstance.CurrentUser 将始终包含您当前登录的用户或 null 如果用户没有登录。这个值实际上存储在C++中，并通过C#访问，这意味着它实际上并不了解或遵守Unity的典型对象生命周期。这意味着，一旦你签入了一个用户，这个值将始终保持当前用户，而不需要跨场景边界持久化。事实上，这个值甚至会在你的游戏运行过程中被保存下来（这意味着你的玩家不必每次都要登录）。
不过需要提醒的是，这个值是异步更新的。CurrentUser 是异步更新的 -- 也就是说，并不能真正保证 CurrentUser 是最新的 -- 所以一般来说，注册一个新的产品是安全的。StateChanged 听者 从文件中:
Firebase.Auth.FirebaseAuth auth;
Firebase.Auth.FirebaseUser user;
// Handle initialization of the necessary firebase modules:
void InitializeFirebase() {
Debug.Log("Setting up Firebase Auth");
auth = Firebase.Auth.FirebaseAuth.DefaultInstance;
auth.StateChanged += AuthStateChanged;
AuthStateChanged(this, null);
}
// Track state changes of the auth object.
void AuthStateChanged(object sender, System.EventArgs eventArgs) {
if (auth.CurrentUser != user) {
bool signedIn = user != auth.CurrentUser && auth.CurrentUser != null;
if (!signedIn && user != null) {
Debug.Log("Signed out " + user.UserId);
}
user = auth.CurrentUser;
if (signedIn) {
Debug.Log("Signed in " + user.UserId);
}
}
}
void OnDestroy() {
auth.StateChanged -= AuthStateChanged;
auth = null;
}
我强烈建议观看我的 Firebase认证教程 来看看我是如何考虑将其与游戏整合的。的 分享链接 是合适的，但我对你代码中的各种REST调用有点好奇。
如果您使用的是 Firebase Unity SDK, 电子邮件密码认证 应该像创建用户和
auth.CreateUserWithEmailAndPasswordAsync(email, password).ContinueWith(task => {
if (task.IsCanceled) {
Debug.LogError("CreateUserWithEmailAndPasswordAsync was canceled.");
return;
}
if (task.IsFaulted) {
Debug.LogError("CreateUserWithEmailAndPasswordAsync encountered an error: " + task.Exception);
return;
}
// Firebase user has been created.
Firebase.Auth.FirebaseUser newUser = task.Result;
Debug.LogFormat("Firebase user created successfully: {0} ({1})",
newUser.DisplayName, newUser.UserId);
});
创建一个用户和
auth.SignInWithEmailAndPasswordAsync(email, password).ContinueWith(task => {
if (task.IsCanceled) {
Debug.LogError("SignInWithEmailAndPasswordAsync was canceled.");
return;
}
if (task.IsFaulted) {
Debug.LogError("SignInWithEmailAndPasswordAsync encountered an error: " + task.Exception);
return;
}
Firebase.Auth.FirebaseUser newUser = task.Result;
Debug.LogFormat("User signed in successfully: {0} ({1})",
newUser.DisplayName, newUser.UserId);
});
来签到。也就是说，应该不需要使用 RestClient.
2）实时数据库
一旦你通过了身份验证，任何呼叫到 Firebase实时数据库SDK 将自动使用 CurrentUser 值(正如我之前提到的--它在SDK的C++端持续存在)。
如果你希望使用 规则来保护用户数据的安全 如：
{
"rules": {
"users": {
"$user_id": {
// grants write access to the owner of this user account
// whose uid must exactly match the key ($user_id)
".write": "$user_id === auth.uid"
}
}
}
}
那么 写数据:
Database.DefaultInstance.GetReference($"/users/{FirebaseAuth.DefaultInstance.CurrentUser.UserId}/mySecret").SetValueAsync("flowers");
应该就可以了。
希望能帮到你
