ah, i think this is one of those great examples for local/default
so if it is a bus, if one player is controlling it, leave it default?
but if it is a single race car, then local?
to me this is still confusing since somehow i had assumed anything involving movement is supposed to be local
The way I like to think about it is: if it's a single player interaction, local. If it's a shared interaction, server side.
for the tutorial world mobile, when you rotate the cylinder in Room B, would another player see you rotate it or just yourself?
Everyone will see it. There's an API that allows you to control who can see what (setVisibilityForPlayers), but you would have to script it to be so. Otherwise, all objects are visible to all players by default, local or not.
