We're creating a MMO and I wonder is RPC safe or not ? Isn't RPC easily hackable by injecting to client and what is the security layer of RPC on Unreal Engine ?
For example; a player is walking and sending that information (new position, rotation etc) to other players, can't that player change movement speed or position with injecting ? What is validating; is that movement is valid or it was a hack ?
I checked on Google but didn't get answer for my questions.
