我目前正在为我在Unity中创建的游戏编写网络后端。我面临的问题是连接到另一台计算机上的服务器（在同一本地网络上）。我对uNet非常陌生并且需要什么，所以非常感谢帮助。
我已经按照了一些教程，但没有一个能解决我所面临的问题。目前还没有连接到服务器的连接。我初始化了服务器，创建了套接字，使用Network.Listen（）来监听通过端口传输的数据包 - 但还没有完成。
这是我在实施游戏之前所做的一个测试项目，很抱歉不那么干净的代码。
IP在Inspector中指定，但使用＆＃34; 127.0.0.1＆＃34;预设它。抱歉混乱！
这是客户端代码：

这是服务器端代码：

非常感谢任何和所有帮助！ 谢谢！
