This 0-Tick Machine Sorts Falling Blocks

This machine sorts falling blocks using 0-tick pistons and some other really clever mechanics, all in vanilla minecraft!
And no, it does NOT work with anvils/dragon eggs/etc. This is because pistons can’t push anvils unless they’re already a falling entity, and pistons break dragon eggs when attempting to push them.

I should note that his device DOES include concrete sorting, but not using block id’s. It sorts concrete powder based on the order in which it was printed out.
If you are using world edit to create a pillar of random falling blocks, you won’t be able to fit all the block names in one command.
Instead, use this command to randomly fill a selected area with all usable falling blocks:

[@michael23b]

Something I should mention: the reason you see item entities on top of the stacks towards the end of the video, is because I placed floating string near the top of every stack. This is so that the piles wouldn’t physically overflow and stop up the machine. When the falling blocks fall directly onto the string, they break and turn into an item, which was useful for demonstration purposes so I could continuously run the device.

[@XyndraNerd]

what about dragon egg and anvil?

[@michael23b]

Nope, cause those can’t be pushed by piston; anvils can’t be moved, and dragon eggs break upon trying to move them with a piston. It only works with concrete powder, sand, red sand, and gravel. It also doesn’t work with suspicious sand/gravel cause those would break upon falling.

Could also be used as more dense (slow) memory for minecraft computers. You could use the 16 colors of the concrete power to represent 4 bits of data, meaning that in a single stack from Y -63 to Y +320 you can store up to (theoritically, you obviously need some room to move the blocks) up to 192 bytes ! It wouldn't be fast enough for a mineraft computer directly I think, but I think you could store your "files", and then load it into RAM when you need it, just like in an oldschool piston loop, except it's 4 times more dense !

This is actually not new knowledge, I personally used this with observers, since they use the same scheduled ticks. Older versions have more interesting falling block mechanics though, like being able to change different blocks into each other.

You did a good job of making this very understandable. Before I watched, it felt like I had no clue how this could possibly work. Mid way through the video, I realized how obvious it is. Good job 👍

[@stanleydodds9]

This is really interesting. Recently there have been a lot of videos about using this interesting falling block scheduler to cause it to incorrectly make things fall when they really shouldn't (essentially abusing it to make it incorrectly do the block id check, turning things like nether portals into falling blocks), but I hadn't even thought of just using this mechanic the way that it's intended to work, preventing things from falling when they shouldn't. That way it's not really using any sort of glitch, so it's extremely simple, but it's also a really clever use of this game mechanic to do something that would otherwise be impossible (save from using other glitches - we all know of the old systems that could change the metadata of blocks, turning sand into red sand, or changing the colour of concrete powder).

[@Nooticus]

[@TheGunMasterDigital]

Damn, that's such an interesting device! I love the essence of the "bug" this relies on. It's not that someone made a very sloppy mistake (which seems to be the case with quasi connectivity). Someone really thought carefully about the scheduled events, and how one should perform a check to ensure the event that occurs corresponds to the block that scheduled it. They did however not account for the fact that it being the same exact same block type does not necessarily imply it's the same block, which is not that obvious. Great builds, and great video and explanation!

[@michael23b]

Thanks! Yeah and it’s not even a bug, it’s just how the game was intentionally programmed to handle falling block events

[@somdudewillson]

It's not necessarily an oversight - there is no way of identifying that it is the same block that doesn't incur performance overhead.

[@JamesTDG]

If this is combined with falling block storage (FBS), you could make the machine technically more compact, plus FBS can make block transit far easier, since you could have the system send the whole collection into a stationary storage cluster elsewhere, which can use all 3 dimensions to store falling blocks in their solid state for lag reduction purposes.

[@badumtsy]

I have one crazy idea for improvement for you - in minecraft you can stack certain number of falling block entities in one place (e.g. with explosions) and they should be processed at the same time. When they fall and get placed they can form a huge pillars in one tick (at least that was a thing once, idk if its still in the game). This means that the theorethical thoughput could magnified and counted in "pillars" of falling blocks. The limit would then possibly the height of such a stack.

[@blak4831]

The issue with that is that the blocks need to be in their solid block state while *inside* the machine in order for the falling block check to sort them. Using the compression trick would just have them explode into a pillar while they're in the machine and brick it

The explanation was amazing. This "discovery" (if I could say, I may attribute credits to the wrong people) is frankly amazing. Working with the scheduler & the fact that falling blocks are POSITION-checked, and not BLOCK-checked is something I didn't even think of when playing the game. Amazing job!

[@jesselapides4390]

I guess it makes some sense programming-wise. If they were checked based on the block itself, then every single block would have to be unique, kind of like entity UUIDs, which would slow down the game considerably (or maybe even break it) because of the sheer amount of blocks.

You mentioned building connect 4 using the sorter. Since I watched the video I have been working on a prototype for it (with super messy redstone lol), currently have the game itself working, except it's not replayable yet, because my system to empty the concrete from the game is too fast for the sorter to handle. Gotta figure that out, but when I do, I'm 100% gonna build it on our SMP, so I'll let you know when that video is up!

[@CZminecraftvideos]

Well you can always divide flow of blocks into 2 or more sorters to match the speed of the emptying system. I don´t think you can make the sorting system itself quicker, and slowing the empying system doesn´t seem like a good thing either.

[@ScubaKay]

@@CZminecraftvideos Great idea! I was thinking of storing the blocks in a giant tower and then sorting one block at a time whenever a player makes a move, but that would become very bulky very soon!

[@CZminecraftvideos]

​@@ScubaKay Storing blocks is helpful too. Instead of player input to sort them one by one, just sort them all at once automatically . So build the sotrage size to fit one game, or even more games and you can start sorting by designated button, or maybe just sort in background while playing (not sure how laggy the whole system will be).

The concept is simple 😮 A simple delay you can use it to id falling blocks. Nice this is very creative

Just out of curiosity, since I'm a player who likes to play old modded versions, would this work on older versions (such as all the way back in 1.7.10) and with modded blocks or has minecraft changed stuff about redstone and update orders since then that made this work? (I specify modded blocks cus I know in vanilla, you'd only have gravel and sand and red sand back then)

Scaffolding was added in 1.14, so you need at least that. Scaffolding is used in the machine to get a 1 game tick delay

There are other ways to get a 1-gt delay pre-1.14, but it’d make the machine much larger, and if you’re playing all the way back in 1.7.10 at that point you can use a sand to red sand converter because those weren’t patched out yet.

No, the only reason you see items is because I intentionally placed string near the tops of the piles in order to prevent the piles from stacking too high and stopping up the system. By placing floating string, the falling blocks break upon dropping onto said string, which for demonstration purposes allows me to continuously run the machine without worrying about it clogging up. I should’ve mentioned it in the video but oh well

would this also work for anvils and dragon eggs? I'm guessing not for anvils since they have all the NBT states of how much they have been used, even if they arent yet one of the other blocks. but surely it would work for dragon eggs if you had a lot of them and were using them for some reason.

[@michael23b]

Pistons can’t push anvils unless they’re already a falling entity, so this will not work. Also, pistons break dragon eggs when attempting to push them, so it will also not work for that

Hello, this is a incredible contraption that can sort blocks but items that i ve ever seen, can I repost it on bilibili so people in China can watch your video?

[@andre_601]

I can be wrong, but I think 0 tick contraptions fire in the same redstone tick, not game tick. The reason I say this is, that there are 2 game ticks for every redstone tick, with redstone ticks being 20 per second. Not sure if I'm right here. Just heard this once before... But I believe I'm somewhat right as there needs to be one tick to actually process the block movement from how I understand the game logic.

[@axialeaa]

“the same gametick” is accurate here. redstone ticks don’t actually exist as far as the game code is concerned; they’re just named as such to approach understanding redstone components which usually work in multiples of 2 gameticks. for example, repeater delay is stored as a numerical blockstate from 1-4, but they calculate delay per blockstate by multiplying the blockstate value by 2 (1 -> 2 gametick delay; 2 -> 4 gametick delay; 3 -> 6 gametick delay; 4 -> 8 gametick delay). zero tick technology operates on the fact that minecraft is a single-threaded game which means no 2 things can truly schedule to happen at the exact same time. it will always prioritise one event over another, even when they occur within the same gametick. these distinctions are measured as “subticks”, and by manipulating the order in which they occur, you’re able to create circumstances where the activation is scheduled “before” the instantaneous deactivation. the reason why the repeater and comparator are used in this video’s demonstration is because of tile tick priority or ttp. the first thing the game does is schedule the repeater to activate the piston. this happens first because repeaters have a higher ttp than comparators. next, the comparator is scheduled to power the piston which cuts off the power source the repeater provided. these two things happen in the same gametick, so the piston extends and begins retracting instantaneously. it’s a little bit confusing and i didn’t explain it very well here. ttp and other similar ideas are hard to work around since you can’t really see them. my reference to “nothing can truly happen at the same time” is really in reference to the way the code orders things that happen, not literal time-wise distinction. i hope this helped anyway! :)
