Store type configuration #

When making hard currency purchases, set the correct EconomyStoreType based on the player’s platform. The store type determines which platform’s receipt validation endpoint the server uses.

For more details on store types and purchase validation, see Virtual Store.

Initializing the economy system #

The economy system relies on the Nakama System and an ILogger, both must be passed in as dependencies via the constructor. You must also specify the store type for receipt validation.

Subscribing to changes in the economy system #

You can listen for changes in the economy system so that you can respond appropriately, such as updating the UI, by implementing the IObserver pattern, or use the SystemObserver<T> type which handles it for you.
