Server Hosting Code

So you may have looked at the MultiplayerMenu.cs file and noticed there is a lot of amazing useful code samples there, but sometimes all that code can be a bit overwhelming and How do I start a server? is all you want to know. Below is a sample of how to start a UDP Server and a TCP Server.

UDP Server

int maxAllowedClients = 32;
UDPServer server = new UDPServer(maxAllowedClients);
server.Connect();

TCP Server

int maxAllowedClients = 32;
TCPServer server = new TCPServer(maxAllowedClients);
server.Connect();

It is worth noting that both UDPServer and TCPServer implement the IServer interface and derive from the NetWorker. So there are many casting and generic options to choose from. There are arguments that go into the Connect methods of these types, but they are for the Master Server and Nat Server.

Assigning to Network Manager

Hard to believe?, Yes that is all the code you need to start up a server, now there is one more important piece of business we must complete. Since this server is most likely going to be the main communication NetWorker with the clients and the game, you are probably going to want to set it up as the default NetWorker for the NetworkManager to use. You can do this with the following:

// The server object is the same object from the above code samples
NetworkManager.Instance.Initialize(server);

By doing this, the passed in server will be the NetWorker that is used for all communication managed by the NetworkManager. This includes spawning objects, RPC calls on those objects, scene transitions and so forth.

Please note that you should instantiate the network manager prefab yourself, like the MultiplayerMenu does, else the network manager's singleton instance will be null!
