The public interface of an underlying store system (e.g. Google Play or Apple App Store) typically exposed to Unity IAP extending its in-app purchasing platform support.
Unity IAP is extensible, supporting registration of store systems through IPurchasingModule
implementations shared with Unity IAP via a ConfigurationBuilder
during initialization.
A sample store class:
#pragma strict // Purchases always succeed at the sample store internal class SampleStore implements IStore { public const var Name: String = "samplestore"; private var m_Biller: IStoreCallback; private var m_PurchasedProducts: List.<String> = new List.<String>(); public function Initialize(biller: IStoreCallback) { m_Biller = biller; } public function RetrieveProducts(productDefinitions: ReadOnlyCollection.<ProductDefinition>) { var products = new List.<ProductDescription>(); for (var product in productDefinitions) { var metadata = new ProductMetadata("$123.45", "Fake title for " + product.id, "Fake description", "USD", 123.45m); products.Add(new ProductDescription(product.storeSpecificId, metadata)); } m_Biller.OnProductsRetrieved(products); } public function Purchase(product: ProductDefinition, developerPayload: String) { // Keep track of non consumables. if (product.type != ProductType.Consumable) { m_PurchasedProducts.Add(product.storeSpecificId); } m_Biller.OnPurchaseSucceeded(product.storeSpecificId, "{ \"this\" : \"is a fake receipt\" }", Guid.NewGuid().ToString()); } public function FinishTransaction(product: ProductDefinition, transactionId: String) { } }
using System; using System.Collections.ObjectModel; using System.Collections.Generic; using UnityEngine.Purchasing; using UnityEngine.Purchasing.Extension;
// Purchases always succeed at the sample store internal class SampleStore : IStore { public const string Name = "samplestore"; private IStoreCallback m_Biller; private List<string> m_PurchasedProducts = new List<string>();
public void Initialize(IStoreCallback biller) { m_Biller = biller; }
public void RetrieveProducts(ReadOnlyCollection<ProductDefinition> productDefinitions) { var products = new List<ProductDescription>(); foreach (var product in productDefinitions) { var metadata = new ProductMetadata("$123.45", "Fake title for " + product.id, "Fake description", "USD", 123.45m); products.Add(new ProductDescription(product.storeSpecificId, metadata)); } m_Biller.OnProductsRetrieved(products); }
public void Purchase(ProductDefinition product, string developerPayload) { // Keep track of non consumables. if (product.type != ProductType.Consumable) { m_PurchasedProducts.Add(product.storeSpecificId); } m_Biller.OnPurchaseSucceeded(product.storeSpecificId, "{ \"this\" : \"is a fake receipt\" }", Guid.NewGuid().ToString()); }
public void FinishTransaction(ProductDefinition product, string transactionId) { } }
FinishTransaction | Called by Unity IAP when a transaction has been recorded. |
Initialize | Initialize the store. |
Purchase | Handle a purchase request from a user. |
RetrieveProducts | Fetch the latest product metadata, including purchase receipts, asynchronously with results returned via IStoreCallback. |
