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. |
