Rollback Netcode

Rollback Netcode My understanding of rollback is that the game actually does extrapolate events based on the last server update If you have a ping of a few tens of milliseconds the difference between the client s guess as to what will happen and what actually does happen will rarely differ enough to disrupt gameplay or be visually jarring endgroup

Server receives input at T1 All clients receive the change at T2 At T2 however using client prediction Client A is now at a position appropriate to T4 It probably would be useful to think in terms of server time Its probably very similar to how interpolation works Every command is sent up with a server time Reliability basically incurs a cost of having to resend your RPCs having to order them and also waiting to make sure they all arrive in order This can eventually increase latency and may not be what you want for a fast paced game What you could do is queue up your input commands and re send them manually and order them on your end

1 I m working on implementing combat into my isometric RPG game which uses an ECS architecture When synchronizing the actions of the different clients is it preferable to serialize and synchronize raw components actions or a mix of both For example an action might be entity X attacks entity Y whereas the components approach would need I have an authoritative system where when the player joins the match it gets all the already spawned objects spawned on itself the client It looks like this Client sends the access token

RTT or round trip time is the time that it takes to send a message and receive the result from server As I searched this this seems to be the same as ping in network jargon Are there some It s a lot harder than I expected and the more I get into it the harder it gets My current approach is to split the problem into 2 steps Generate a complete solved Sudoku puzzle Remove numbers until it s solveable and has only 1 solution In step 1 since I m using a brute force methods I m facing some run time issues

Unless you re in a LAN situation or have really good netcode you ll need to up your latency a bit to make this all work Say 75 100ms or so In general the idea is this controller data is tiny Mouse positions on the map clicks buttons etc All very small So you can afford to shove several ticks worth of data into a single packet Use messaging for any communication between the network subsystem and game engine and for that matter between any two subsystems Inter subsystem messaging can be a simple as a blob of data passed by pointer using std list Simply have an outgoing messages queue and a reference to the game engine in the network subsystem
