Code Mystics Explains Netcode: Input Delay vs. Rollback

Attention, fans of online fighting games: We put together this Netcode primer to explain Rollback vs. Input Delay, and also how to tune Code Mystics' netcode settings to give you the best online fighting experience!

For those asking, we'd be keen to add rollback to any games we're asked to, but it's going to be up to the owners of those games whether or not it's done. So, it's not us you have to convince, it's them. :)

Thank you for giving amazing potential to Nickelodeon's Smash Bros

Question, what is the song used for the video?

[TSMSnation]

people want rollback for smash but that sounds horrible. thing about falcom just standing there then suddenly your hit by a falcon punch in 1 frame with no start up.

Who’s here after project slippi was announced

Based Code Mystics. I recognize you guys from the ports of the original Killer Instinct games to Xbox One. Glad to see you guys are also contributing to community discussion!

[luxerhusku]

You guys are amazing! Thank you for adding this to Garou! Hope you guys will be able to add this to other great SNK classics!

Just so I have this straight:

Delay=Your game will feel slightly sluggish because of the delayed inputs
Full Rollback (badly implemented Rollback)=Teleporting mid-match when the connection's rough
Partial Rollback (what people expect Rollback to be)= The game buffers slightly but hopefully it's too quick for people to really notice, so even bad connections should feel solid without too much mess, hopefully.


Did I get anything wrong here?

And then we have Nintendo using 100% delay-based because the general concept of rollback wasn't an in-house idea >:(

[meyeneetuks]

Bruh Thems Fighting Herds, an indie fighting game developed by a handful of people, got better netcode than these AAA companies lol

[hsiangyuchen]

Can play Garou from Taiwan to California nearly no lag. Please add rollback to kof98um and 2k2um. Show Arc Sys you're the better dev

[vigorouspringle]

I tried reading about rollback in fighting games and it made no fucking sense this video made it 100% clear to me

[PikminExpert]

Thanks for the amazing netcode update for Garou!

[HauntedFennie]
