I'm making an online multiplayer game, sort of a survival game.
In multiplayer everything is working, players can pick characters, chop wood, make fire etc.
Single player should basically run as the host but without letting anyone join
-lock when full don't work even at 0 as 1 person can join
-Not allowing to join room works but has weird bugs.
What is the correct/easiest way to make single player out of a completely multiplayer project?
