I know absolutely nothing about how to code internet or network functions in games or applications currently. Basically what im wanting to do is transfer player coordinates between the server and client. Therefore the packet of data which would be sent would include only a few bits of information. How about would I do this using TCP/IP in delphi? Any links or code would be useful

Once I have this sorted then I can use this system to detect whether the user has the current map (on my RPG), and if not download the new one and any images which the user requires... But that is something further down the line.
