bullet Physical engine will it cause out of sync?
use on server. no out of sync
that is State synchronization! Server just forwards user events!
that’s bad. server should forward state.
…or things can get out of sync.
A network of machines can’t even agree on time, let alone anything else.
Edit: I mean, you can do it. You’d have to strictly single-step bullet. Strictly and exactly control the timing of everything, etc. And one little thing goes wrong and “poof”. You will spend 70% of your development time supporting that solution.
