[edit] The Basics of Usage
First, create RakClientInterface and RakServerInterface objects in their respective applications.
[edit] Server Side
Use the Start member function of the RakServerInterface object to open the port and start listening for incoming connections. You can specify the port number and the maximum allowed number of players to be connected to the server at any one time (up to 65535) through this function. If you need to ban an IP address, you can use the AddToBanList member function to ban someone. To kick someone, use the Kick member function with the Player ID of the player to kick as a parameter. Call the Receive member function to fill a Packet structure with received data. Check the first entry ([0]) of the data member of the Packet structure against the server-specific values in the PacketEnumerations header file to find out what kind of data was received. When replying to the client, use the Send member function.
[edit] Client Side
Use the Connect member function of the RakClientInterface object to connect to the server. You can specify the server address and port number of the remote server through this function. Call the Receive member function to fill a Packet structure with received data. Check the first entry ([0]) of the data member of the Packet structure against the server-specific values in the PacketEnumerations header file to find out what kind of data was received. When you need to reply to the server, use the Send member function.
