What is does the sync behavior do?- I have players customizing their color but it doesn’t show for the other user’s screen.
I assume that you are talking about the Shared Behavior, but same thing. Anyways, according to the Multiplayer Handbook, Shared Behaviors hold a value that remains the same for all players. So if the value contained within the behavior is a 6, then the Shared Behavior will output a 6 for all players anytime it is triggered. If the value contained is an 8, then the behavior will output an 8 for all players when triggered.
So I could use it for private lobby hosting like in COD, where the host of the server can choose maps, weapons, game-mode, etc.?
