Yep, I don’t doubt that that would work.
Initially I was going to write my own NodeJS based socket server for the game I’m working on, and I’d have had to do all that with it as well. By using the UE4 server I was trying to avoid having to write things like that. More specifically by writing it for a pawn I’m concerned about losing interpolation/extrapolation that the character has.
Perhaps the examples they give in 4.2 will shed some light on how better to do this for Pawns rather than Characters.
