Update Suppression Explained

Complete explanation of update suppression.
Update suppression changed in 1.14.x. The same setup wont work but update suppression itself works. Given the changes its unsure what will work and what wont. Update order is certainly different, duping is still possible and few other changes removed some features like meta data conversion and old method of portal slicing. Given this video was made for 1.12 then someone else have to try figure out what has changed.

oh man finally someone properly explained how it worked, thanks xcom!

[@jasoncharters1041]

I am so thankful, Xcom also explained random tick properly in another video. He is an extremely underappreciated youtuber

[@techman8817]

Kayleigh figured out a fix for 1.13 slicing. Just use a vine instead of banner. Also the update suppressor needs to be reset manually in that version. I tried and it works.

[@m33r61]

Wouldn't it be better to use something like a ladder? since a vine could grow and cause an update from random ticks?

[@insert-yes]

how do I reset it?

Really great and easy to understand video about this topic! I fully agree with other commenters that there is finally a clear explanation for how this stuff works! Thank you Xcom as I appreiciate you going over things a few times in the video so 'dummys' like me can understand :P

[@haph2087]

So the way this works is that the game uses a depth first algorithm rather than a breadth first algorithm and that the particular order is highly predictable and thus easily manipulable? Lovely. The explanation was awesome. Update suppression always seemed like black magic to me, this video really helped me understand how it works, how it can be used and how it can't. I really hope the crash patch for non-player updates comes to vanilla. That might open up some fun new things to mess around with.

[@psyneur9182]

In case your interested, I just built, in 20w12a, an ~800 ish banner chain (I didn't really count, but around there) with a stack size of 160k. I broke the block supporting the first banner, and my game crashed with a stack overflow. After restarting my game and loading the world, it did work and created a broken nether portal. The banners were placed on the west-side of the block. Edit: Did some investigation in the source (using the yarn mappings). The blocks are updated in a slightly different order now: west, east, north, south, down, up. The check for a stack overflow has been removed. The only reference to stack overflow anywhere in the source is to print errors as a string. So yeah, they just broke this.

The default stack size on MAC is 32M

[@techman8817]

Very informative. I wonder how low you could lower Xss and still be able to make a working machine and still have Minecraft be playable.

[@Xcom6000]

-Xss64k is lowest java allows but I would say that limits sit around 320k. Lower and even redstone dust can cause update suppression in diamond patterns. I wouldn't go lower then 128k given portal blocks being removed have huge pointer counts and the fill up the stack size fast would result in update suppressed portals when doing a 21x21 portal causing server crashing removing the portal blocks with dispensed liquids.

[@gebruikersnaamhuh]

thanks for the explanation!

[@frush1921]

So first of all... thanks that is super well explained ^^ Second I was wondering with the banner trick if you could do a single use bannerline that would be enough update to fill the stack (or if banner has some small value in stacks ) (This would make for a pretty safe système and working well for supressing just one or two time ) How many banner would that be ? About the same as the number of rails ?

[@floskater99]

Yes, you can do that, but it's better to use carpets (cost less, and way easier to place). You can place all the carpets ontop of a row of signs. (When you break the first sign, all others pop off too, and the carpets ontop pop of too) You need about 2400 blocks. So just make a 50-block long row of signs, and stack carpets ontop, 50 blocks high. Needs to be on the WEST-side of the block you wanna update-supress / break. Contact me if I should give you a tutorial.

[@frush1921]

@@floskater99 I tried a few times and it crashed every single time x') but it did the update supression so overall its fine and a lot more safe than an updatable thing for removing blocs ^^

its fixed in 1.16

[@wabch]

@@blackdragon4187 to what extent though, what way was it fixed in? are all updates the same in 1.16? is the update system completely redone to state where its fundamentally different? has the way the limit been implemented different? all of these? the way hes asking the question implies he already knows that it doesnt work anymore.

[@sandowebb7302]

Could you not continuously fill the stack and just break blocks and not have updates

[@rednexium4100]

There’s an old method that if you have a repeating signal, to a dropper while in a crafting table and spam the fill on console with a keyboard, it will duplicate the item,

I tried doing update suppression with 25600 banners and it didn't do update suppression or crash my game :-( EDIT: I am dumb they need to be all in a single chain not multiple branches

Not "nothing" works on paper servers, but this doesn't, update suppression is fixed in spigot

[@mattdos7171]

When you say this can cause server crash, do we mean it only crashes the game of the person who has it loaded/does the update? Or it crashes the entire server?

[@Xcom6000]

server

[@Firigion]

Can you do automated update supression with a smaller contraption using RS dust, since they give out a ton of updates? I think Panda used soemthing like that at some point during the update supression fever.

[@Firigion]

Maybe something like this? Upper piston is budded. You'd still need to hook it up to a budded rail, but I think this might be easier to build, if it works. prnt.sc/objm0w

[@Xcom6000]

@@Firigion Can't use pistons given pistons don't use recursive calls. Piston updates goes through BlockEvent updates and its based on a while loop updating pistons in a list. Given that its not possible to overflow the stacks using pistons. Each piston empties the stack and re-fills it. The budded redstone has to be part of torches that pops off. Its possible to use redstone torches that can pop off when placed against stairs that aren't in the correct state. But its not reusable as this system is.

[@Firigion]

@@Xcom6000 Thanks! I was in the discord and people tried explaining that, but where way less clear than you ^^

[@ladder5199]

Is it possible to use this on spigot/paper vanilla servers?

[@multiDomains]

Do the rails really need to be budded? Can’t you just depower all the rails at the same time without budding them? Can’t you just lay down an instant rail line many blocks long and trigger it?

[@adamrezabek9469]

How would you power thousand of rails, when they have max lenght of powering from one source?

It was patched in 1.19, works in versions before.

[@SoKelf]

I can use this for "item shadowing"? (It work for this?)

[@KiwiRedstone]

Item shadowing is about updating stack id. Update suppression just suppresses the change of stack id which makes two slot have the same stack id; therefore, the stack is synced.
