I'm creating a multiplayer game. This is my first time interfacing with a game this way, and I wanted to know when I should actually start implementing netcode, etc. Looking online, I've seen that it's fine to do it both at the beginning and at the end, but I'd prefer to discuss it with someone who may have encountered the same question/problem.
When did you do it?
If you did it at the end, did you encounter any problems converting everything?
