This guide describes the process of establishing the digital records and relationships necessary for a Unity game to interact with an in-app purchase store.
In-app purchase (IAP) is the process of transacting money for digital goods inside an application. A platform’s store allows users to purchase products, which are digital goods. These products have an identifier, which is typically a string data type.
Products have types to represent their durability:
Like the Apple App Store and the Google Play Store, the CloudMoolah MOO Store is a commercial online service that enables people to buy and sell mobile apps, and buy items in the application.
The MOO Store serves Asian markets. Users maintain a digital wallet, which they can top up using a variety of payment providers, such as banks and convenience store pre-paid cards.
The CloudMoolah Developer Portal website is at dev.cloudmoolah.com.
Make a game that implements Unity In-App Purchasing (see Unity In-App Purchasing Initialization and Integrating Unity In-App Purchasing with your game for more information).
Keep the game’s product identifiers on hand for use in the MOO Store later (this document discusses appKey
and hashKey
later).
This example configures and starts initialization of Unity In-App Purchasing:
using UnityEngine.Purchasing;
public class MyStore : IStoreListener {
public void InitializeStore() {
var module = StandardPurchasingModule.Instance();
var builder = ConfigurationBuilder.Instance(module);
builder.Configure<IMoolahConfiguration>().appKey = "d93f4564c41d463ed3d3cd207594ee1b";
builder.Configure<IMoolahConfiguration>().hashKey = "cc";
builder.Configure<IMoolahConfiguration>().SetMode(CloudMoolahMode.Production);
builder.AddProduct("100.gold.coins", ProductType.Consumable);
UnityPurchasing.Initialize(this, builder);
}
}
In the Unity Editor, configure the Android target to CloudMoolah to ensure that store is accessed when a purchase is attempted:
Install the Unity In-App Purchasing package, then find the Unity In-App Purchasing menu in Unity’s Window menu: Window > Unity IAP > Android > Target CloudMoolah. This ensures that, when the app is run on the Android operating system, it uses the CloudMoolah API to fulfill in-app purchase requests.
Alternatively, call the Unity Editor API: UnityPurchasingEditor.TargetAndroidStore(AndroidStore.CloudMoolah);
When the game successfully completes initialization of Unity In-App Purchasing, bind to the user’s Cloud Moolah digital wallet with the IMoolahExtension.FastRegister
and IMoolahExtension.Login
API. In the game’s implementation of IStoreListener.OnInitialized, use the IMoolahExtension.FastRegister
API to register a new digital wallet for the user, and the IMoolahExtension.Login
API to access a user’s existing wallet.
IMoolahExtension.FastRegister
requires a user identifying string cmPassword
. This string is also required by the Login
API to unlock that user’s digital wallet, and their collection of owned IAP products. Ensure the string identifies this user uniquely for your application. Collect FastRegister’s cmUserName
result, and use that in subsequent calls to IMoolahExtension.Login
. Save this cmUserName
on your backend server, if available, or in PlayerPrefs.
See the scripting documentation in the CloudMoolah Store for further discussion of registration and login.
Build a signed non-Development Build Android APK from your game. See documentation on getting started with Android development to learn more about this.
Tip: Take special precautions to safely store your keystore file. The original keystore is always required to update a published app.
Register the app at the CloudMoolah Developer Portal website (dev.cloudmoolah.com).
Choose Add New App.
Input game server information if you are defining a game that is connected to the internet.

At the CloudMoolah Developer Portal (dev.cloudmoolah.com), select Add New Item to add in-app purchases for this app.
The CloudMoolah Game Store supports testing. Enable developer mode in the app before making purchases (do this via IMoolahConfiguration.SetMode
API - see below). This special build of the game provides a fake offline store which performs performs fake purchases. This does not incur real-world monetary costs related to the product, and allows you to test the app’s purchasing logic.
To modify the game’s MOO Store test mode, create the ConfigurationBuilder
instance and add the following line, then build and run the app to test its in-app purchasing logic:
builder.Configure<IMoolahConfiguration>().SetMode(CloudMoolahMode.AlwaysSucceed); // TESTING: auto-approves all transactions
To test error handling, configure this to fail all transactions. To do this, use tthe CloudMoolahMode.AlwaysFailed
enumeration. For example:
builder.Configure<IMoolahConfiguration>().SetMode(CloudMoolahMode.AlwaysFailed); // テスト: 常にすべてのトランザクションを失敗させます
Note: When you have finished testing, make sure you remove the SetMode
line that disables Developer mode, and use the CloudMoolahMode.Production
enumeration. This ensures users pay real-world money when the app is in use.
