How to Use Simple Firebase Unity: A REST API Wrapper for Unity in C#

If you’re looking to connect your Unity applications to Firebase, but are struggling with the official Unity Firebase SDK aimed primarily at mobile platforms, look no further! The Simple Firebase Unity plugin simplifies the integration of Firebase Realtime Database into Unity projects through its REST API. Let’s dive into how to set it up and troubleshoot any hiccups along the way!

Getting Started with Simple Firebase Unity

• Installation: To utilize the Simple Firebase Unity plugin, you can find it on the Unity Asset Store. Download and import the plugin into your Unity project.
• Setup: After importing, make sure to delete any existing .dll files from prior versions, as the namespace has been updated to SimpleFirebaseUnity.
• Basic Configuration: Once imported, you can create a Firebase instance by calling:

  Firebase firebase = Firebase.CreateNew("samplefirebaseunity.firebaseio.com");

  You will then be able to communicate with your Firebase database using the available methods.

Basic Usage

The beauty of this plugin is in its simplicity. The common requests to the Firebase Realtime Database—like getting values or updating data—can be achieved with just a few lines of code. Picture this as giving your friend a call. You simply dial their number (the Firebase endpoint) and ask for the information you need.

firebase.GetValue(); // Like asking "What's up?"
firebase.SetValue();  // Like saying "Please save this for me."
firebase.UpdateValue(); // Like saying "Update the info I gave you."
firebase.PushValue();  // Like asking "Add this new data."
firebase.DeleteValue();  // Like saying "Forget about that data."

Each method corresponds to a specific HTTP request type, making it intuitive for developers familiar with REST APIs.

Firebase Queue

If you have multiple requests that need to be processed in order—like a waiter taking orders at a busy restaurant—you can utilize the FirebaseQueue class. It efficiently queues requests so they run sequentially.

FirebaseQueue firebaseQueue = new FirebaseQueue();
firebaseQueue.AddQueuePush(firebase.Child("broadcasts"), name: "simple-firebase-unity", message: "awesome!", true);
firebaseQueue.AddQueueSet(firebase, GetSampleScoreBoard(), FirebaseParam.Empty.PrintSilent());

Handling Real-time Changes with FirebaseObserver

Since Firebase doesn’t provide push notifications for data changes via the REST API, we can simulate this through the FirebaseObserver class. Think of it as setting up a recurring meeting with a colleague to check on progress.

FirebaseObserver observer = new FirebaseObserver(firebase.Child("timestamp"), 5f);
observer.OnChange += ChangeHandler;

This observer will periodically check for changes in the specified key, allowing you to respond swiftly without overwhelming the system.

Troubleshooting

While using the Simple Firebase Unity plugin, you might run into a few issues:

• Cannot Connect to Firebase: Ensure you’re using the correct Firebase endpoint URL and that your Firebase project is properly configured.
• Authorization Failed: If using Firebase Secret for authorization, ensure it’s correctly inputted. For more secure methods, consider using generated tokens.
• Data Not Updating: If your requests seem delayed or unresponsive, verify the network connection and ensure that the Firebase database rules allow writing to the endpoint.
