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.

@Infil 3 года назад

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.

@CoreAGaming 3 года назад

You have the best article I've seen on the topic. I wouldn't have understood rollback netcode without it. This video just scrapes the surface.

@oklimbo 3 года назад

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.

@KnakuanaRka 3 года назад

@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.

@A_Lazy_Mutt 3 года назад

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.

@victornguyen1175 3 года назад

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.

@reNINTENDO 3 года назад

Excellent description! This is one of those things that's been around for a long time for FPSs, but from what I've heard fighting games were pretty late to the party. Though honestly that's not surprising. A single bullet is a lot less complicated to make look okay than meticulously crafted frame data in a fighting game animation. One thing I love about this concept is the nomenclature used. I don't know if it's used for fighting game netcode as much, but when dealing with some of this myself when making a top down game I read about/had to deal with "dead reckoning" (en.wikipedia.org/wiki/Dead_reckoning). The name is edgy as hell for something that's largely "yeah, the cat's probably still sleeping".

Amazing breakdown that made me understand it easy and super awesome editing. GJ!

@RanOutOfSpac 2 года назад

There was a point where my stupid ass brain thought that netcode for 3rd Strike on the Ps3 was worse than SF4. My internet was shit, so the amount of roll back frames I got was extremely noticeable. So even though I had like 12 frames of input delay in SF4, my brain was like “wow this game isn’t as choppy!” I realized my mistake after I began watching Maximillion Dood a bajillion years ago. Really glad this video exists cause now I don’t explain what roll back is every time I bitch about a game’s net code to friends.

@STone600k 3 года назад

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.

@tobylast3153 3 года назад

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.

@SonofTzeentch 3 года назад

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?

@salvatronprime9882 3 года назад

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.

@milesfarber 2 года назад

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.
