Unity 内购（InAppPurchasing）

艾克索拉 Mobile SDK 通过提供扩展模块，实现了与 Unity 内购的无缝集成。

您只需在代码中的任何位置配置并初始化它，然后即可开始处理购买。

配置与初始化

public class MyIAPManager
{
    
    // ...

    public MyIAPManager()
    {
        var settings = XsollaStoreClientSettings.Builder.Create()
            .SetProjectId(77640)
            .SetLoginId("026201e3-7e40-11ea-a85b-42010aa80004")
            .SetSandbox(true)
            .Build();

        var configuration = XsollaStoreClientConfiguration.Builder.Create()
            .SetSettings(settings)
            .Build();

        var module = XsollaPurchasingModule.Builder.Create()
            .SetConfiguration(configuration)
            .Build();

        var builder = ConfigurationBuilder.Instance(module);
        builder.AddProduct("100_gold_coins", ProductType.Consumable, new IDs
        {
            { "100_gold_coins_google", "com.mycompany.mygame.100_gold_coins_google" }
        });

        UnityPurchasing.Initialize(this, builder);
    }

    // ...

}

完整实现

我们的代码基于现有的官方 Unity IAP 示例代码 "01 Buying Consumables"：

代码示例：

using UnityEngine;
using UnityEngine.Purchasing;
using UnityEngine.Purchasing.Extension;
using UnityEngine.UI;
using Xsolla.MobileSDK.Common;
using Xsolla.MobileSDK.Store;
using Xsolla.MobileSDK.UnityPurchasing;

namespace Samples.Purchasing.Core.BuyingConsumables
{
    public class BuyingConsumables : MonoBehaviour, IDetailedStoreListener
    {
        IStoreController m_StoreController; // Unity 购买系统。

        // 您的产品 ID。它们应与商店中产品的 ID 相匹配。
        public string goldProductId = "com.mycompany.mygame.gold1";
        public string diamondProductId = "com.mycompany.mygame.diamond1";

        public Text GoldCountText;
        public Text DiamondCountText;

        int m_GoldCount;
        int m_DiamondCount;

        void Start()
        {
            InitializePurchasing();
            UpdateUI();
        }

        void InitializePurchasing()
        {
            // 删除原始代码中的这一行。
            //var builder = ConfigurationBuilder.Instance(StandardPurchasingModule.Instance());

            // 添加以下代码。
            var settings = XsollaStoreClientSettings.Builder.Create()
                .SetProjectId(77640)
                .SetLoginId("026201e3-7e40-11ea-a85b-42010aa80004")
