Unity与Cryptocurrency IOTA API的集成

Question

我正在致力于将IOTA集成到Unity游戏引擎中，任何具有c＃编程经验以及三元逻辑和IOTA经验的人都可以帮助我了解通过Unity发送交易所需的操作，我正在开发Android该应用程序可以从钱包中向用户提供IOTA付款（我通过游戏中的广告获得付款），我从felandil的c＃库中配置了一些代码，但我不断收到类似以下错误：IotaApiException：Command getTransactionsToApprove失败了！

    }

    void SendMessage(string nodeUri, string sendAddress, string message)
    {

        RestIotaClient iotaClient = new RestIotaClient(new RestClient(nodeUri));
        PoWService powService = new PoWService(new CpuPearlDiver()); // the examples will use the CPU to do PoW for a transaction.
        RestIotaRepository repository = new RestIotaRepository(iotaClient, powService);

        Bundle bundle = new Bundle();
        bundle.AddTransfer(new Transfer

            Address = new Address(sendAddress),
            Message = TryteString.FromUtf8String(message),
            Tag = Tag.Empty,
            Timestamp = Timestamp.UnixSecondsTimestamp
        });

        bundle.Finalize();
        bundle.Sign();

        repository.SendTrytes(bundle.Transactions, 27, 14);

    }
