Unity 编辑器无法连接到 Firebase 身份验证

Question

我是来制作一个带有firebase auth的匿名登录游戏，以及一个带有firebase实时数据库的数据库，除了firebase auth之外，一切都很顺利。问题是我不知道为什么？ unity 不会连接到 Firebase 身份验证。

安装

我已经像always database和auth一样安装了软件包

对于火力基地也是这样

脚本

这里是我的登录脚本：

//Firebase variables
    [Header("Firebase")]
    public DependencyStatus dependencyStatus;
    public FirebaseAuth auth;
    public FirebaseUser User;
    public DatabaseReference DBreference;
    public static FirebaseManager instance;

    void Awake()
    {
        if (instance != null)
        {
            Destroy(gameObject);
        }
        else
        {
            DontDestroyOnLoad(gameObject);
            instance = this;
        }

        FirebaseApp.CheckAndFixDependenciesAsync().ContinueWithOnMainThread(task =>
        {
            dependencyStatus = task.Result;
            if (dependencyStatus == DependencyStatus.Available)
            {
                InitializeFirebase();
            }
            else
            {
                Debug.LogError(
                    "Could not resolve all Firebase dependencies: " + dependency status);
            }
        });
    }

    public void InitializeFirebase()
    {
        auth = FirebaseAuth.DefaultInstance;
        DBreference = FirebaseDatabase.DefaultInstance.RootReference;
        auth.StateChanged += AuthStateChanged;
        AuthStateChanged(this, null);

    }

    void AuthStateChanged(object sender, System.EventArgs eventArgs)
    {
        //This checks if the user (your local user) is the same as the one from the auth
        if (auth.CurrentUser != User)
        {
            bool signedIn = User != auth.CurrentUser && auth.CurrentUser != null;
            User = auth.CurrentUser;
            if (signedIn)
            {
                Debug.Log("Signed in " + User.UserId + " " + User.DisplayName);
            }
            else
            {
                StartCoroutine(SignAnonymously());
            }
        }
    }

    //it does not directly log the user out but invalidates the auth
    void OnDestroy()
    {
        auth.StateChanged -= AuthStateChanged;
        auth = null;
    }

    public IEnumerator SignAnonymously()
    {
        var loginTask = auth.SignInAnonymouslyAsync();

        yield return new WaitUntil(predicate: () => loginTask.IsCompleted);

        if (loginTask.Exception != null)
        {
            //If there are errors handle them
            Debug.LogWarning(message: $"Failed to register task with {loginTask.Exception}");
        }
        else
        {
            User = loginTask.Result;
            Debug.LogFormat("User signed in successfully: {0} ({1})", User.DisplayName, User.UserId);
        }
    }

我尝试过的

• 检查 google-service.json（已相同或已更新）
• 由于兼容性问题，已实施此 https://firebase.googleblog.com/2020/08/firebase-compatibility-with-unity-20201.html。
• 已将 continuewith 更改为 ContinueWithOnMainThread(task..

注意：我使用的是 unity ver 2020.3.1f1 LTS

我做错了吗？

尝试用这个异步方法替换你的协程方法 import pyautogui, time true=True false=False running = false def execute(): time.sleep(2) running = !running while true: if running == true: pyautogui.press("w") ：

SignAnonymously

我认为问题可能是在您的 public async void SignAnonymously() { await auth.SignInAnonymouslyAsync().ContinueWith(task => { if (task.IsCanceled) { Debug.LogError("SignInAnonymouslyAsync was canceled."); return; } if (task.IsFaulted) { Debug.LogError("SignInAnonymouslyAsync encountered an error: " + task.Exception); return; } Firebase.Auth.FirebaseUser newUser = task.Result; Debug.LogFormat("User signed in successfully: {0} ({1})", newUser.DisplayName, newUser.UserId); }); } 末尾缺少 ContinueWith，也许您可​​以在协程中使用它，但我从未这样做过，请告诉我它有效^^
