Ok, so I've made some sort of Dungeons and Dragons game in C that plays in a Console. I want to make a two player version (or more?) where two people on a LAN can play together against a common enemy! How can learn about making programs talk across a network? All it needs to do is transmit simple commands like "Pick object" ect. I really don't even know where to begin! What protocols could I use? TCP/IP?
Thanks in advance!
