Crazy how this concept seemingly comes from how you would actually predict your opponent's moves in real life, by assuming they are gonna keep doing whatever they are doing until your brain actually "registers" the shift in motion a split second right after the move is made. Which is why the reason why it feels much better and more natural than delay netcode.
Can I just say that man is a fucking 'G for making it free under MIT? Imagine making such an incredibly useful, innovative and game-changing netcode and going "Here you go guys, just take it".

Great job on the video! The other thing we did on Killer Instinct was also make sure the general input lag (button press to visual change) was as low as possible in addition to the rollback code.
This will make my life so much easier when explaining this to people. The fact you managed to make it make sense in less than 10 minutes with time to spare is blowing my mind.
@Manek Iridius Yes, some stuff is still dropped, but the point is that synchronizing things via rollback causes the game to differ from a perfect connection only in brief moments where it isn’t that important, while delay based net code causes a desynchronization between inputs and in-game actions that is far more disruptive to gameplay even with small amounts of delay.
I have a match in Fantasy Strike with someone across the globe, like literally on the other side of the Earth (SEA to USA). Yet, the match feels like offline. Rollback is magic
@@yomamapkme it will (but this isnt an excuse to use wi fi) the more tolerable the netcode is more matches with not so fast internet you can get(like 120 to 150ms)

Now we've got a rollback crusader video with Core A production values. Fantastic. Also thanks to all the gg fans shouting so loudly that ArcSys decided to take the plunge and add rollback to strive.
Excellent video Gerald (and thanks for linking my rollback article)! Wanted to add 2 points to even further strengthen the argument for rollback: 1) Even if you live near your opponent, delay-based netcode doesn't work very well because the internet frequently delivers packets inconsistently (especially on WiFi). Rollback is very good at handling subtle moments of packet loss or ping spikes, even if your overall connection is fast and your opponent is close. It's this *consistency* that is rollback's biggest strength and it's why we need it for all games, even if we don't plan on playing over long distances. 2) Combining rollback with some initial delay at the start is much better than delay by itself, because the chosen delay remains consistent and unchanged in the hybrid approach, as opposed to the input delay constantly fluctuating with the connection quality in the pure delay approach. Again, it shows that consistency is the main benefit of rollback -- any uncertainty created by the network is instead handled through the prediction algorithms and occasional rollbacks, instead of forcing the user to feel the effects and undermine their strategy.
@@alexanderespinoza The whole peguin meme was a reaction on how european tournaments tended to be underrepresented in official rankings, when Leffen brought that to people's attention, a now famous reply said something among the lines of "If we are going to consider results from europe in our rankings we may as well consider ranking penguins from antarctica"

Another thing I think is (mildly) important to consider is the fact that bad delay-based netcode and bad rollback have completely different effects. Bad DBN is just frustrating, while bad rollback can at least be somewhat amusing in how ridiculous it looks.
@@Apsandman On the bright side though, nowadays rollback is talked about more constantly, awareness that it exists is more widespread, and people demand it more from companies, just a few years ago it wasn't talked nearly as much, so at least there's more awareness now.

The only side effect I noticed the entire time was noticeable rollback when they jumped a couple times, but it was seriously impressive compared to Ultimate where the same connection had a full quarter second of input delay.

It's probably due to corporate demands. The same reason why an entry level job offer will require "10+ years of experience." Companies want to save money, and the guys on top running the business and who don't understand much about the nature of the product they're creating don't want to spend more getting employees who know how to implement proper rollback. Business executives are notoriously cheapskates and likely don't see the benefit of improving a game's online experience if the player numbers and sales remain stable. In other words, it's corporate ignorance.
It's those first too letters of your post that keep it from already being a thing in fighting games. It's a standard feature in American developed fighting games. Killer Instinct, Mortal Kombat X & 11, Injustice 2 and a ton of indy games have rollback.
Please, please, please speak up about it. If the JP devs won't listen to us maybe they will listen to the JP core audience. I can only dream of the day where KOF and Samurai Showdown have rollback, and living outside the USA only makes netcode worse
I swear after the round table, not 2 days ago I watched Code Mystic's video on how rollback and input delay work. I immediately thought this would be a great video topic for Core-A to go in-depth into and whaddaya know. A video on exactly that comes out. Great as always!
1:30 is one of the reasons I love your videos, makoto's theme is straight fire and it always fits nature of the content you provide... Please never change it lol
The fact that we can have rollback in melee which definitely has the most insane input strings in fighting games and it still feels super super smooth despite the amount of 1-2 frame moves like shine and jabs being so heavily used is a testament to how amazing this is and if the melee community can do it for such a crazy high input game then capcom really needs to get on the wagon.
@@Inriri To be fair, Mario Kart Rollback is really easy. If theres lag, then just hold their current inputs. As soon as lag is over, then just roll it back. But for Arms... I don't understand why they put any effort into that game's online.
As a developer of a multiplayer game using rollback (and a big fan of the channel) this is the most approachable and informative introduction to rollback that I've seen. The animations are awesome too. Great job!
Hey Core-A, you'll probably never read this, but I was watching your "consequences of lowering the skill gap" video. I was wondering, could you do a video about "the consequences of RAISING the skill gap"? Some games like For Honor are experiencing that now, and the social aspect surrounding it is fascinatingly frustrating.
That 100ms of input lag effects a small portion of the smash community. Smash is meant to be a party game evidenced by items, wacky and unique stages, and a more simple fighting game that almost everyone can pick up and play. Not many people will ever notice the 100ms delay or ever will
@@lumnary7635 It's a party game that has fighting game DNA and therefore has a very high skill ceiling for the players that want to play to challenge themselves. Those players will notice and feel the delay.
Really like the short and frequent content mixed in with the long form. You guys do good work. And it’s wholesome. Which is why I watch. I barely play fighting games. Keep it up!
I was playing granblue with a friend, and when I got up to use the restroom he changed my controller input delay to 10 frames, and it took me a while to notice because I'm used to shitty connections.
Thank you so much for helping me understand this!!!! I hear my friends and other FG youtubers talk about rollback and I never knew what it was or they just explained it really poorly. Keep it up Core-A 👍
Wow this was awesome! Well explained and demonstrated/visualized, just the thing I needed! I'm just getting into fighting games, and these types of videos are just what I need to quickly learn all the ins and outs, makes learning a lot more efficient and allows my monkey brain to process and store all this info. I can see your passion show in this 1 video alone, so I will definitely be binging the rest of your videos! You earned a sub with this one mate, it must have been hard work just to make this short explainer video, I know a lot of people don't realise just how much work something like this takes, with all the graphics and demo reels that are needed. Also, putting the sponsor at the end is a welcome change from having it shoved in my face in the first 30 seconds. All around, well done and keep up the good work!

Going back to this video weeks after Tekken 8's release. The efforts people have done to try to spread the good word of Rollback will never be forgotten. Now to enjoy this video again~
Imagine the revitalization of scenes that have died because of lack of competition. Those small niche communities would then have a way to connect with each other. Or take a huge fighting game like DBFZ and implement GGPO plus cross platform 😩 god the future of fighting games is looking bright
I think you need to take a look at the source code for Quake 3 Arena (Q3A) before you attribute latency compensation to Tony Cannon. Q3A came out in 1999 and the source code was released in 2005. It had all of the netcode features you've described. Q3A would predict where a player is going to be based on their last inputs just like you've described here. If they were last know to be running forward, it would assume they were still running forward. It would also snap players to their correct location when a network message came through to show that their input had changed and the predicted location was wrong. Furthermore, there was "rollback" on attacks in the game as well. If a player fired a rocket 45 ms ago and you just learned about it, your game would show the rocket as if it had been in flight for 45 ms already. I'd have to go back and check to see if it rolled back animation as well (player animation is much less important in a FPS than a fighting game, so it may not have). You could also dial in your input delay in ms instead of frames (like GGPO frame delay). Q3A didn't try to negotiate "rift" -- but that's because the game had a variable framerate (in-game time isn't based on frames), so rift didn't exist. Someone running the game at 15 fps could connect and play against someone running at 125 fps without any issues.
I was going to mention this. Also Unreal Tournament 99 had a community-developed netcode called "zeroping" and another called "newnet" which added all these features back in 2002 (maybe earlier). If you look at the Unrealscript files included with the game you can see that the game had been designed with rollback in mind although it wasn't fully implemented at release. The great thing about Unreal is that when you connect to a zeroping or newnet server, it automatically updates netcode and implements it for you. You don't need to install or anything at all to use it.
4:50 in the league fighting game ekko as a dose a frame 1 teleport every combo… this man real told people what not to do and then just did it what a mad lad
This going to sound crazy but hear me out, I've noticed some devs are reluctant to implement Rollback because they have an agenda to the casual playerbase. I noticed Rollback is implemented in most often aggressive games which have more actions going on to predict for RB, which I feel like protects the wifi player because they'll attempt to be sneaky/mash. Slow reactionary footsie games (The ones that matter, not counting Punch Planet) don't have it still to protect wifi players because according to Harada, Tekken's playerbase is 50% wifi. Probably like that for a lot of FGs which harms the ladder experience for otherwise decent players.
The biggest issue with rollback netcode is grabs. Let's say your opponent is walking forward and you grab him, but then he rollbacks to a jumping state. What happens to your character? The ideal situation would be that your character goes immediately back to idle animation so you can block or counter the aerial. But in 99% of games with rollback, thanks to developer incompetence, your character does the "got his grab parried" animation. You got punished for successfully grabbing an opponent. This is especially damning with p2p, where the opponent can just modify the information they're sending with third party tools, or even use lag switches.
Hope you guys find this video useful! Rollback netcode is not the future, it's now. Fighting games without it are behind.

@@Cafetos0777 The most recent port of Garou: Mark of the Wolves has rollback, and the upcoming Guilty Gear Strive will have it on release.
I've been playing Guilty Gear strive online and to me it's been indistinguishable from me playing offline in training mode. It's incredible
Woah 2 Core-A videos in the same month awesome!
*A Gamer's Worst Enemy:*
1. Lag
I'm still making nightmares of 19 frames delay matches I've played in DBFZ
2: minorities
Why end with that shot of Tekken, Harada told us it already has rollback!
TK7 is 3!
read well!
I think I remember Harada being against rollback in the first place.
@@Boyzby it's gonna be 6!
@Kayden I like both, but I definitely like SFV a lot more
Balance was one thing Tekken 7 always had over SFV, but that might not be the case anymore
I swear after the round table, not 2 days ago I watched Code Mystic's video on how rollback and input delay work. I immediately thought this would be a great video topic for Core-A to go in-depth into and whaddaya know. A video on exactly that comes out. Great as always!
1:30 is one of the reasons I love your videos, makoto's theme is straight fire and it always fits nature of the content you provide... Please never change it lol
^
The fact that we can have rollback in melee which definitely has the most insane input strings in fighting games and it still feels super super smooth despite the amount of 1-2 frame moves like shine and jabs being so heavily used is a testament to how amazing this is and if the melee community can do it for such a crazy high input game then capcom really needs to get on the wagon.
Now I know what Sajam was telling him off the mic
Needed this channel in my life. Really love to know the technicalities and know how's of how things work.
TFW you just remembered that Playstation All-Stars even had an attempt at Rollback yet Super Smash Brother's still hasn't
Edit: Officially.
BRUH
And
Tfw the playstation all-stars community didn't have a single controversy in it's lofetime of 1 second
Well Nintendo hasn't, but Melee's got slippi now so we good
Even sillier is that Mario Kart and Arms have rollback.
@@Inriri To be fair, Mario Kart Rollback is really easy. If theres lag, then just hold their current inputs. As soon as lag is over, then just roll it back.
But for Arms... I don't understand why they put any effort into that game's online.
@@omarg2079 because Arms is made by internal Nintendo. Smash is developed by Bandai Namco
Wow. This was a fantastic breakdown/explanation of not just roll back netcode, but the concept of netcode as well.
Amazing content as always.
DBFZ is finally getting Rollback netcode support! 😎👍
really cool depiction of the european smash scene at 0:50
You'd think the Nickelodeon platform-fighter wouldn't have rollback netcode, yet here we are.
As a developer of a multiplayer game using rollback (and a big fan of the channel) this is the most approachable and informative introduction to rollback that I've seen. The animations are awesome too. Great job!
DSP punching air right now.
3 Core-A videos in less than a month. This is the dream.
Hey Core-A, you'll probably never read this, but I was watching your "consequences of lowering the skill gap" video. I was wondering, could you do a video about "the consequences of RAISING the skill gap"? Some games like For Honor are experiencing that now, and the social aspect surrounding it is fascinatingly frustrating.
I always kinda knew what rollback netcode meant but this video made it way more clear to understand. Thank you!
smash ultimate fans:
please we want rollback melee has it now
It is unplayable online.
@@LogMeInGoddamnit it's already unplayable offline even if you use a wired controller, 100ms of fucking input lag
Ultimate is a party game made for couch mp
That 100ms of input lag effects a small portion of the smash community. Smash is meant to be a party game evidenced by items, wacky and unique stages, and a more simple fighting game that almost everyone can pick up and play. Not many people will ever notice the 100ms delay or ever will
@@lumnary7635 It's a party game that has fighting game DNA and therefore has a very high skill ceiling for the players that want to play to challenge themselves. Those players will notice and feel the delay.
Really like the short and frequent content mixed in with the long form. You guys do good work. And it’s wholesome. Which is why I watch. I barely play fighting games. Keep it up!
I was playing granblue with a friend, and when I got up to use the restroom he changed my controller input delay to 10 frames, and it took me a while to notice because I'm used to shitty connections.
I never really understood what the difference between delay and rollback was, but now I do! Great video!
*sajams' jaw drops and his tongue rolls out onto the table*
Thank you so much for helping me understand this!!!! I hear my friends and other FG youtubers talk about rollback and I never knew what it was or they just explained it really poorly. Keep it up Core-A 👍
Youre good at analogies
I appreciate how brief and informative your explanation of rollback is.
3:02 "can you guess what my sleeping cats will do in the next frame?"
wake up dp?
3 Core-A vids in 1 month, what a blessing!
Calling it out, this whole video was just a setup to show off your perfect cats nuzzling.
Wow this was awesome! Well explained and demonstrated/visualized, just the thing I needed! I'm just getting into fighting games, and these types of videos are just what I need to quickly learn all the ins and outs, makes learning a lot more efficient and allows my monkey brain to process and store all this info. I can see your passion show in this 1 video alone, so I will definitely be binging the rest of your videos! You earned a sub with this one mate, it must have been hard work just to make this short explainer video, I know a lot of people don't realise just how much work something like this takes, with all the graphics and demo reels that are needed. Also, putting the sponsor at the end is a welcome change from having it shoved in my face in the first 30 seconds. All around, well done and keep up the good work!
Guilty Gear Strive, and KOF XV will have Rollback Netcode.
was watching this on some site, but came to youtube so I could like because this video quality and examples are like.........the best I've ever seen on any explanation of anything lol
Core-A gaming rolled back to Gerald. Welcome back Gerald
Going back to this video weeks after Tekken 8's release.
The efforts people have done to try to spread the good word of Rollback will never be forgotten.
Now to enjoy this video again~
Fantasy Strike has some of the best netcode I've ever seen. I legit can't tell if i'm playing someone in another hemisphere
I experienced that on Switch...
But lately ERRORSCREENS
AND I BOUGHT CORE PACK!!
Will wait for update.... Enjoy Boss Rush until then... THIS IS FINE
This is by far the best explanation I've seen on RUclips. Now I understand rollback netcode.
Maximillian Dood will love this video
ｒｏｌｌｂａｃｋヤマレ
He did
I don't know if you guys will ever see this but jesus christ you post literally the highest quality fgc videos on this site, props to you guys
Oh, so it's kind of like how I hit "Like" before even watching this video because I already knew it was gonna be top tier.
What a great video! You made me appreciate this highly technical topic in a way that was easy to understand.
Imagine the revitalization of scenes that have died because of lack of competition. Those small niche communities would then have a way to connect with each other.
Or take a huge fighting game like DBFZ and implement GGPO plus cross platform 😩 god the future of fighting games is looking bright
This was SO helpful. I always heard the terms, but never understood the implications. Very informative, thank you.
I think you need to take a look at the source code for Quake 3 Arena (Q3A) before you attribute latency compensation to Tony Cannon. Q3A came out in 1999 and the source code was released in 2005. It had all of the netcode features you've described.
Q3A would predict where a player is going to be based on their last inputs just like you've described here. If they were last know to be running forward, it would assume they were still running forward. It would also snap players to their correct location when a network message came through to show that their input had changed and the predicted location was wrong. Furthermore, there was "rollback" on attacks in the game as well. If a player fired a rocket 45 ms ago and you just learned about it, your game would show the rocket as if it had been in flight for 45 ms already. I'd have to go back and check to see if it rolled back animation as well (player animation is much less important in a FPS than a fighting game, so it may not have). You could also dial in your input delay in ms instead of frames (like GGPO frame delay).
Q3A didn't try to negotiate "rift" -- but that's because the game had a variable framerate (in-game time isn't based on frames), so rift didn't exist. Someone running the game at 15 fps could connect and play against someone running at 125 fps without any issues.
Id Software was a real pioneer for competitive online gaming.
Question out of curiosity: was this system also used in peer-to-peer games or just in games where clients are synching up to a server?
I was going to mention this. Also Unreal Tournament 99 had a community-developed netcode called "zeroping" and another called "newnet" which added all these features back in 2002 (maybe earlier). If you look at the Unrealscript files included with the game you can see that the game had been designed with rollback in mind although it wasn't fully implemented at release. The great thing about Unreal is that when you connect to a zeroping or newnet server, it automatically updates netcode and implements it for you. You don't need to install or anything at all to use it.
you are right, but companys did not use this for fighting games before ggpo, so its not that wrong to consider what the guy did as well.
2020 is one good year wit how much Core-A Gaming vids were getting :D
I watched the whole Express VPN part because it was so genuine. THIS is how you get sponsored right.
4:50 in the league fighting game ekko as a dose a frame 1 teleport every combo… this man real told people what not to do and then just did it what a mad lad
This going to sound crazy but hear me out, I've noticed some devs are reluctant to implement Rollback because they have an agenda to the casual playerbase. I noticed Rollback is implemented in most often aggressive games which have more actions going on to predict for RB, which I feel like protects the wifi player because they'll attempt to be sneaky/mash. Slow reactionary footsie games (The ones that matter, not counting Punch Planet) don't have it still to protect wifi players because according to Harada, Tekken's playerbase is 50% wifi. Probably like that for a lot of FGs which harms the ladder experience for otherwise decent players.
Yo that happy birthday analogy was god-like. I've had that happen so many times
Why does Tony Cannon look like Computer Science Tyler1
The happy birthday analogy works so well on explaning this topic
The biggest issue with rollback netcode is grabs. Let's say your opponent is walking forward and you grab him, but then he rollbacks to a jumping state. What happens to your character? The ideal situation would be that your character goes immediately back to idle animation so you can block or counter the aerial. But in 99% of games with rollback, thanks to developer incompetence, your character does the "got his grab parried" animation. You got punished for successfully grabbing an opponent. This is especially damning with p2p, where the opponent can just modify the information they're sending with third party tools, or even use lag switches.
This video explained it well for me. I always wondered what Rollback Netcode was. Great job.
Rollback is coming to DRAGONBALL FIGHTERZ
Top notch content, as always.
So when harada talks about tekkens delay being 3 frames he's talking about that rift compensation you were explaining.
