Frequently Asked Questions

How do snapshot listeners work inside Unreal Engine Blueprints?

Our plugin wraps the native C++ listener architecture into simple event-driven Blueprint pins. When a document or collection updates on the cloud, an execution thread fires natively in your Blueprint graph, passing a clean Data Snapshot.

Can I run atomic data transactions to prevent player item duping?

Yes. The Firestore module includes full support for native transaction blocks. It halts concurrent modifications, ensuring inventory additions or currency changes resolve sequentially and securely.

Does the Firestore plugin require constant internet connection to function?

No. Local offline persistence is enabled by default. The plugin handles queries using disk-cached data when offline and automatically pushes queued mutations once connection is re-established.

How do I parse complex Firestore documents into Unreal variables?

The plugin features automatic type-conversion nodes. Easily break apart Firestore maps, arrays, timestamps, and geo-points directly into standard Unreal Structs, FStrings, and Maps.

Does this Firestore module support deep queries and collection groups?

Yes. You can build complex queries using chained filtering nodes (WhereEqualTo, OrderBy, Limit) and execute collection group queries across geographically separated document paths natively.

Is the Firestore implementation fully compatible with dedicated server builds?

Yes. The module compiles cleanly for headless Linux and Windows dedicated servers, allowing authoritative servers to perform admin-level writes and data validation directly.
