unit有iap 代码示例

以下是 Unity IAP 的代码示例：

首先，需要在 Unity 中启用 Unity IAP。在 Unity 菜单栏中选择 Window -> Unity IAP -> IAP Catalog，然后按照提示操作创建一个 IAP Catalog。

然后，在代码中使用 Unity IAP API 来获取和处理购买：

using UnityEngine;
using UnityEngine.Purchasing;

public class IAPManager : MonoBehaviour, IStoreListener
{
    private static IStoreController storeController;
    private static IExtensionProvider extensionProvider;

    public static string PRODUCT_ID = "product_id"; // 购买的商品 ID

    void Start()
    {
        InitializePurchasing();
    }

    public void InitializePurchasing()
    {
        ConfigurationBuilder builder = ConfigurationBuilder.Instance(StandardPurchasingModule.Instance());

        builder.AddProduct(PRODUCT_ID, ProductType.Consumable);

        UnityPurchasing.Initialize(this, builder);
    }

    public void BuyProduct()
    {
        if (storeController != null)
        {
            Product product = storeController.products.WithID(PRODUCT_ID);

            if (product != null && product.availableToPurchase)
            {
                storeController.InitiatePurchase(product);
            }
        }
    }

    public void OnInitialized(IStoreController controller, IExtensionProvider extensions)
    {
        storeController = controller;
        extensionProvider = extensions;
    }

    public void OnInitializeFailed(InitializationFailureReason error)
    {
        Debug.LogError("Unity IAP initialization failed: " + error);
    }

    public void OnPurchaseFailed(Product product, PurchaseFailureReason failureReason)
    {
        Debug.LogError("Unity IAP purchase failed: " + failureReason);
    }

    public PurchaseProcessingResult ProcessPurchase(PurchaseEventArgs args)
    {
        if (string.Equals(args.purchasedProduct.definition.id, PRODUCT_ID, System.StringComparison.Ordinal))
        {
            // 处理购买逻辑
        }

        return PurchaseProcessingResult.Complete;
    }
}

以上代码演示了如何初始化 Unity IAP，如何获取和购买商品，以及如何处理购买结果。请注意，上述代码仅供参考，具体实现可能会因项目需求而有所不同。
