Needle Scene + Firebase

🌵 Needle Engine
1

hey!

just started looking into this

Looking to pull user data down from a database (Firebase) in my Unity scene. I don’t seem to be able to run the script I use to initialise Firebase in Unity? At least, I’m not seeing any logs - have I missed something with the engine’s functionality?:

private async void Start()
{
Debug.Log(“Firebase Manager Started…”);

        if (usingNeedle)
        {
            var init = await InitializeFirebase();
            if (init)
            {
                log.text = "init success";
            }
        }
    }

    /// <summary>
    /// Initializes Firebase asynchronously.
    /// </summary>
    public async Task<bool> InitializeFirebase() {

        try {
            // Check and resolve Firebase dependencies
            var dependencyStatus = await FirebaseApp.CheckAndFixDependenciesAsync();
            if (dependencyStatus != DependencyStatus.Available) {
                Debug.LogError($"Firebase dependencies not resolved: {dependencyStatus}");
                return false;
            }

            // Initialize Firebase services
            Auth = FirebaseAuth.DefaultInstance;
            Firestore = FirebaseFirestore.DefaultInstance;
            Storage = FirebaseStorage.DefaultInstance;
            DB = FirebaseFirestore.DefaultInstance;

            Auth.StateChanged += AuthStateChanged;
            
            Debug.Log("Firebase initialized successfully.");
            initialised = true;
            return true;
        }
        catch (Exception ex) {
            errorHandler.HandleException(ex); // Use the error handler
            return false;
        }
    }

thanks

Hi Nik Jeewon!

It looks like you’re attempting to integrate Firebase with a Unity scene using Needle Engine. There are a couple of aspects you might want to check to troubleshoot your initialization issue:

  1. Unity’s Log Output: Make sure you are checking the Unity Console for logs. If you are not seeing anything, ensure your Debug.Log statements are correctly logging to the console.

  2. Update your Firebase SDK: Ensure that you have the appropriate version of the Firebase SDK for Unity installed. Sometimes, compatibility issues can arise with different package versions.

  3. Use of Async Methods: Ensure your Unity project is properly set up to handle asynchronous methods. If the Unity project hasn’t been set up to handle the async context, it might cause issues in the execution of your async/await code.

  4. Check Needle Engine Compatibility: Verify that you are using a version of Needle Engine that works well with the Unity functionalities you’re implementing, especially for initializing Firebase.

  5. Using usingNeedle: Make sure the usingNeedle variable is correctly set before the if statement. It should be true in compatibility scenarios.

If after checking all of the above it still does not work, please provide additional details, such as:

  • The Unity version you are using.
  • The version of Needle Engine.
  • Any specific errors in the console that might help in troubleshooting.

This context will assist in providing more targeted help for your issue.

Feel free to share the details so we can proceed!

Hi, there are no limits with Needle Engine and connecting to any backend server or hoster. It’s a client side 3d library so if the connection isnt workinh you need to check your backend config or connection code

Also note that you need to write your code in javascript or typescript. Please look at Creating and using Components | Needle Engine Documentation

Ohhhhh - my fault. I just assumed it was the usual Unity based scripts :smiley:

Thanks I’ll check out the docs!
