Origins of the Reliable Shulker Farm

PLEASE NOTE This farm no longer works as the shulker warp has been removed as of the 1.17 release, for a new and improved shulker farm which works in 1.17 please refer to my followup video:
• Reliable Portal Based ...
After the snapshot hit we were excited to experiment with the new features, especially the renewable shulkers. However many players may come accross some frustrating issues when experimenting with farm concepts so I decided to implement solutions to these issues on the farm designe by the Scicraft crew and our friends.
Litematics, these are for the new version of the farm that works in 1.17, so they differ slightly to the video:

Can you reveal the track at the beginning of the video. Name of the track.

i have so many things to say. First i discovered your channel very recently, and I ABSOLUTELY LOVE, how you explain things. You explain litteraly everythin there is to know and that is fantastic! Bonus point : a lot of people do that, but they are not all great speaker. You are one, and I love hearing you explain these things. I'm just sad of two things here: I would've love to see a bit more the shulker reloader. I expected you to put a string on the snowball to detect if there is a shulker, but not the rest. I would've used a pulse extender(with a torch on it to reduce lag) and as soon as the signal goes off, we send another shulker. This would mean that there is a little downtime when there's no shulker, as the change isn't immediate, but I thought it was fine. However you didnt do that, and I didn't really get to see what you did., There was a line of powered rail that was activating with each snowball, and a redstone line next to it. But then I didn't really get to see the rest. Also, I'm afraid this farm will become obsolete, because of the shulker through portal "bug", and that it will become obsolete. There will still be a way to do this farm, but not as cleanly and easily as this one. And am I correct to assume this farm would be perma loaded as shulker goes through both dimension ? or did it also change in future versions ? lastly, you said the chunk loader would auto destruct if there was a portal ? why is that ?

[@cubicmetre]

Check out the world download and you will find that the shulker detector uses a pulse extender so that when the snowballs aran't detected for a while it sends another shulker. There are also a lot of other specific details that require a proper tutorial to explain however I want to wait for Mojang to finalise the implementation of the feature before I do this. So for now just grab the world download and experiment with things yourself.

[@awerick3441]

Using 23 snow golems in the center will increase the rates but also the lag. Have you done any testing regarding mspt/iph as a function of golem count? Since if you want to build multiple modules the lag-efficiency would be critical.

[@cubicmetre]

Cramming the golems is simply to optimize a single cell layout. I can't imagine scaling up to additional modules would be very lag efficient, even if you made it 1 golem per module you still need separate shulker replacement systems for each cell where each one needs a decent buffer of shulkers to re-stabilize after losing a shulker. You would need exponentially more minecarts for collecting and distributing shulkers. Overall I'd imagine the entity lag bottleneck would be primarily from shulkers and minecarts.

[@OOvdbvOO]

@@cubicmetre Just stack up the farm so that only one nether side part is needed. Not sure how to deal with the overworld side

[@moonlightshadowpony]

I'm looking at this setup and wondering if there's a way to do this without the glitches. an example being the fact that you could cover all but the top faces of the nether portal so you can pick up the shulkers in a minecart, transport them over to another portal, then do the same in the overworld, dropping them on a grass block covered in buttons on all sides with a wither rose, allowing for you to realistically build this farm anywhere and not just super close to spawn.

[@cubicmetre]

I'd suggest you watch the followup video I made when mojang patched the shulker warp bug.

[@eanerickson1968]

I really like that you gave us the formula to be able to calculate these types of things

[@travcollier]

Sadly, that formula was overly complicated. Easier way is: Chance of failure each try is 0.5. So chance it fails 5 times in a row is (0.5)^5 PS: In his formula... 5!/5! = 1 and anything to the 0th power = 1. So same time.

[@Redsammeh]

Neat video! I'm trying to research as much as I can before I build a farm (I don't want it to become obsolete when I update!) Could you balance the audio a bit in future videos? I found it a bit hard to hear you over the music (though maybe others find it to be fine, idk)

[@madman2572]

Great video cubic! I have a question for you? So: There is a 3% chance of a shulker not duplicating with each bullet in this setup (established in video) A shulker has 30 health and does 4 health of damage when open (wiki) A shulker needs to be reduced to half (15) health to have a 25% chance of teleporting without replicating (video and wiki) A shulker would need to hit itself 3 times to lower its health to 18, which means that on the next hit, it will be lower than half health (math) So you need 3 successive failed attempts before there is a 25% chance of failure?, then another 25% chance of failure on the 4th attempt and so on... So: Σ 0.03^n * 0.25 for n=3→∞ 0.03^3 * 0.25 ≈ 7 in 1Million chance of failure? (neglecting the very small probabilities after initial n=3) If you are seeing this shulker disappear regularly, obviously I am wrong. Just wondering where my math fails?

[@cubicmetre]

You are correct, however there are other variables at play. Your analysis actually made me rethink how the shulkers are lost. If you look very closesly around 7:42, I tick warped the system until the shulker disappeared from the centre. If you look closely you will see a shulker failed to go through the nether portal at the same moment the shulker disappeared from the centre. Another factor which affects the shulker duping is other shulkers. In fact the probability for a shulker to dupe decreases depending on the amount of shulkers nearby, if 1 other shulker is present the probability to dupe drops to 50%! That pesky shulker which failed to go through the nether portal was stuck in a weird state where they would not open their shell, I've observed this happening a few times. The presence of this shulker means that there is a 50% chance for a dupe to fail, which over repeated trials very quickly breaks the farm.

[@madman2572]

@@cubicmetre Thanks for the response! A 50% fail rate would certainly break very quickly if any shulkers stuck around. I just started messing around with the snapshots after seeing this video. Looking forward to playing with shulkers.

[@eagle-from-aut]

i think shoulker warping causes more issues than it solves. on wavetech we also have a shoulker based owerworld mobswitch that doesnt rely on this technique and it is an absolutely beautiful build, all without shoulkerwarping iirc. the downside is that there has to be string on every surface. its just a very, very strange behaviour that makes no sense to the casual player whos experience this is could revolutionize. i personally dont like it much but it doesnt really cause that many problems, so i mostly dont mind

[@qmalamos]

If you do this farm at 0, 0, you could make the nether portal automatically load the whole nether comtraption? Shulkerbox would go to 0,0 in the nether and the linked portal will be at 0,0 too, so you will have that 3x3 chunk loaded, with that would you be able to fit the whole nether part?

[@lumberwand]

I like the auto filling feature for the case when the shulker dies but how would it scale to larger farms? Such as the tileable one on the snapshit server.

[@jarmingho]

great video! very well explained! couldn't wait to see more players making the farm and with more great ideas!

[@AChaser00]

Is this multi-dimension setup feasible in single player, with needing loaded chunks?

[@moonlightshadowpony]

Every time an entity enters into a nether portal a 3x3 square of chunks automatically become loaded. So if you could find a way to compress this farm in a way that would allow for this form of loading to occur than maybe, otherwise it might just be something you do gradually.

[@kingcassio55]

Why not use instant health potions using a witch farm, or other sources of health potions.

[@cubicmetre]

Methodz tried using potions to prevent shulker loss, at one point he was using a command block to spam insane healing effects on the shulker and it still got lost eventually. The theories discussed in this video cannot fully explain why the shulker disappears.

[@_spidieye_1709]

I just built the farm on my survival world in 1.17 and it works great. The only problem is the mine carts they often get out of sink and stop all together. This means you have to enter the box of death and restart the mine carts. I’m currently working trying to figure out a solution. But was wondering if anyone else has had this problem or knows a solution.

[@cubicmetre]

If you built the system in this video then that's your problem, This design is extremely outdated. My followup video has a design where the nether side should be 100% unload proof. I ran it just the other day and the minecarts never stopped.

[@michaelzoller5303]

But why does the shulker fire in the opposite direction of it's target(s)?

Shulkers just do that, the bullet tracks towards the target so the shulker doesn't even need to aim its shot anyway.

can't a witch from an attack be used to heal him? 😊

[@cubicmetre]

I experimented with the concept of using witches for renewable potions with buffs however the issue is that the witch will only throw buff potions during a raid which can eventually expire, as for healing the shulkers, Methodz used commands to apply insane effects to the shulkers and they still disappeared sometimes.

Great design! A new minecart storage may reduce tps (by a little)

[@cubicmetre]

The minecarts are constantly recycled and stored as items when the system is idle, that is the most lag efficient way to store minecarts.

[@andrewprice8241]

I think it should be kept as a feature because the never-despawning attribute of the shulkers and their post-game position sets them apart as being strange and otherworldly, emphasized even more by the fact that they now multiply in an entirely unique way.

This is a pretty interesting farm concept. Having to load the shulker location is annoying especially for SMP worlds. I think keeping them in the overworld would be worth the lower rates for simplification.

[@cubicmetre]

Honestly I think it would be easier to make the portal based system, to keep them in the same dimension would require a much more complex setup that would have less teleportation spaces resulting in more shulker losses which would make things just such a pain in the butt.

Amazing video! I do think that shulker warping should be patched. However, I don't think that the overworld mob switch you showed is impossible to build without it, given a copious supply of invisibility potions. Its just too obviously not how the nether is supposed to work, even if it is convenient. And I feel that portal-based farms are already too easy to design and build.

[@cubicmetre]

Yeah I kinda regret mentioning the shulker warping as a feature. When you think it through, it really stinks to have to travel to the same coordinates in the nether to reach the nether side of the farm.

[@magnusanderson6681]

@@cubicmetre eh, I don't think its necessarily bad for it to exist either - it only happens if the shulker doesn't find a spot to teleport to, so its definitely avoidable (most of the time).
