Frequently Asked Questions

How does the plugin interface with Unreal's Online Subsystem (OSS)?

It operates as an independent data and identity layer. You can use it alongside platform-specific OSS setups or independently to handle cross-platform cloud saves and cross-play user indexing.

Can this Firebase plugin validate game state to prevent cheating?

Yes. You can invoke Firebase Cloud Functions to pass transaction requests. The serverless backend validates packet data before executing modifications inside Cloud Firestore.

Does this backend setup support game cross-progression?

Yes. By using Firebase Auth to bind multiple platform identity tokens to a single unique Firebase account identity, progress and inventory data sync uniformly across PC, mobile, and consoles.

How does the backend infrastructure scale when traffic spikes?

Google Cloud scales the underlying serverless architecture automatically. Firestore and Realtime Database scale out horizontally to manage thousands of concurrent open socket connections without rate limiting.

Can I orchestrate a matchmaker using Firebase databases?

Yes. By utilizing the realtime listener bindings on Firestore documents or Realtime Database paths, you can track queue parameters and use Cloud Run microservices to group players into sessions.

What is the structural performance impact on authoritative game servers?

The performance overhead is extremely minimal. Offloading player profile parsing, save validation, and analytics logging to Firebase frees up dedicated server CPU resources to handle physics and actor replication.
