UNet 客户端断开连接错误:NetworkClient.Connect 上的 CRCMis match

Question

我需要一些真正的帮助。我不确定如何解决CRC不匹配错误。我要做的就是将字节数组从我的客户端发送到我的服务器，但出现此错误：

UNet 客户端断开连接错误：CRCMismatch UnityEngine.Networking.NetworkIdentity：UNetStaticUpdate（）

一个多月来，我一直在尝试将这些点连接起来，让网络正确运行，但我每向前迈出一步，都会导致后退五步。我基本上一直在兜圈子，我已经完成了所有存在的 Unity 网络教程，但我仍然很迷茫。我真的需要帮助解决这个问题。有人可以帮我解决这个问题吗？我还在下面附加了完整的代码。提前谢谢你！

Answer 1

我通过在client.Connect(serverIP, port);之前添加client.Configure(cc, 1);来解决我的问题。问题是我的网络客户端连接配置文件需要设置为我的网络传输主机拓扑中定义的相同配置设置，而不为我的客户端设置连接配置。连接功能导致CRC不匹配。此外，在创建 NetworkClient 实例后发送消息时，我使用 client.SendByChannel 以便我可以设置我的 channelId。

Answer 2

部分或全部 ConnectionConfig 值必须在主机上和客户端上匹配。当我指定不同的断开连接超时值时遇到相同的问题。
