Finally the wait is over! A new DevLog video – with a demonstration of real, actual, proper, working networking – as promised.
This video shows four copies of the game talking to each other on my local machine. But I have successfully tested the networking on my local network.
At the moment the clients find the server using a local network broadcast. I need to add in some kind of UI (or at least command-line option) before it can be tested across the Internet – so the clients know where to find the server.
