Unity2021.3.35f1，运行模式为ENGINE_SERVER

1.环境设置

 Windows设置

 安卓设置

2.代码修改

ConnectionProperties中的server必须与真实IP一样，所以需要新增一个获取IP的函数

public string GetLocalIPAddress(){IPHostEntry host;string localIP = "0.0.0.0";host = Dns.GetHostEntry(Dns.GetHostName());foreach (IPAddress ip in host.AddressList){if (ip.AddressFamily == AddressFamily.InterNetwork){localIP = ip.ToString();}}return localIP;}
