当我在编辑器上进行测试时，我在游戏中实现了tcp网络，一切正常，但构建后没有任何效果。
我已经尝试过多次更改代码以使其正常工作，但似乎我的代码中缺少某些内容。
我还使用debug.log来控制它的动作，并且一切都可以在编辑器中正常工作，但在构建中却无法正常工作，我已经在普通版和调试版两个版本中构建了它。
我的代码没有错误。
在调试版本中，debug.log根本无法工作。
这是我的服务器代码

答案 0 :(得分：2)
在服务器代码中以tcpListenerThread开始并在客户端代码中调用ConnectToTcpServer();的行已被注释掉。
似乎没有调用两种方法start_server()和connect()。
这可能是为什么在构建中它不起作用的原因。
此外，您尚未实现在退出应用程序时杀死这些进程的例程，并且Unity不会跟踪您创建的线程，也不会自行杀死它们。这可能是您的应用程序似乎可以在编辑器中运行的原因。我想您首先用这些行来运行它，然后再将它们注释掉。在随后的时间内，您点击 play ，线程从第一次开始就仍在运行。
在使用完这些线程后，您应该绝对实现某种例程来杀死它们。

即使这个问题很老 - 我最近遇到了一个类似的问题，想分享一下这个问题是什么。
如果您构建到 Android，请确保在播放器配置文件中启用了互联网连接
当应用程序“从编辑器运行”时，Unity 似乎有一个虚拟网络。因此，您不仅要构建客户端，还要构建服务器应用程序。构建客户端无法连接到“在编辑器中运行”服务器。
