I’m developing a game that can be played with computer or versus other players. The GUI is Swing but irrelevant for the matter. My question is : how do I connect with other players in a network?
I am familiar with terms like client / server, sockets etc, and i can write a basic client/server program, but it can only be run from ONE computer. I don’t know how to connect to this network from a computer, say, half way across the country.
You are probably setting behind a router which hides your local IP address from the rest of the world (look for NAT for more info on this). Basically, the world only sees your YOUR_ROUTER_IP, your router takes care of carrying all IP packets from the outside world to you and vice versa. You will need to change your router settings so that your computer/server gets the router ip address. This way you can access your server application from anywhere in the world by using simple socket operations.
I hope this helps.
