Naw, at first I was thinking of sending the clients input key to the server and c_moving it on the server, but I ended up just doing c_move on the client then using similar code for both server and clients. You could do your moveing on the server, but if your in a fast paced game it would be wise to always have some sort of client prediciton in place as well. I believe in locos tutorial he does the movement on the server and uses native A6 update methods to relay the positions back. I think it's best to turn off all A6 automatic updates and do everything yourself using send_rate.
