API Reference of GS2-Money2 SDK for Game Engine

Specifications of models and API references for GS2-SDK for Game Engine

Model

EzWallet

Wallet

Currency in the wallet is managed separately for currency purchased for a fee and currency obtained for free. Currency purchased for a fee is further managed by the unit price at the time of purchase, allowing for refunds in the event of service termination, or to determine if the balance is sufficient to meet the requirements of the Funds Settlement Act.

The wallet has slots and each slot has a different balance. If balances cannot be shared across platforms, they can be managed separately by using different slots for each platform. Currency acquired for free can also be shared across all platforms.

Warning

This event is called when the value in the local cache that the SDK has is changed.

The local cache will only be changed by executing the SDK’s API, or by executing a stamp sheet via GS2-Distributor with GS2-Gateway notification enabled, or by executing a GS2-JobQueue with GS2-Gateway notification enabled. GS2-Gateway notification enabled.

Therefore, callbacks will not be invoked if the value is changed in any other way.

This event is called when the value in the local cache that the SDK has is changed.

Therefore, callbacks will not be invoked if the value is changed in any other way.
