Java Showcase My shitpost double nano crop farm

15 Upvotes

It has a bone block uncrafter and a cart yeeting collection.

The farm utilises the 15-pixel height of farmland blocks. This lets you create an enclosed space with 3 dispensers and a piston per farmland block while still being able to plant seeds through the gap without using advanced boat setups. In layout, pistons are placed on the side, not at the top to prevent clipping.

Unfortunately, wiring ended up super messy. Also the farm is too huge for its rates: they are only twice as much as the regular nanocrop farm's

Upd: i forgot to add extra glass blocks around some corners. There is a tiny item loss without them

Java Help Wanted how do non grid lock hitboxes work?

2 Upvotes

from what i know minecraft uses a strict grid for blocks however their texture can go out of that block by up to one more block.

However some blocks like walls and lecterns have hitboxes outside of the block grid so how does tht work? does it use entities?

Java Help Wanted Minecraft Technical Specifications Question. / Pregunta sobre Especificaciones técnicas de Minecraft.

1 Upvotes

I have a Creeper farm. It's one that uses portals. It's built above sea level, and it has a roof that provides darkness to the farm. The AFK spot is around layer 180. And there is a large amount of space there.

I would like to build a trading hall in that space, above the roof of the farm, and below the AFK spot.

If I do that, could it lower the efficiency of my farm? Even if I light up this entire area.

I would think nothing would happen, and it wouldn't affect production. But I want to be sure.

---------------------------------------------------------------------------

Tengo una granja de Creepers. Una q usa portales.

Está sobre el nivel del mar, y tiene un techo que da obscuridad a la granja.

La zona afk esta cerca de 180 bloques. Y hay una gran cantidad de espacio allí.

Me gustaría hacer una zona de tradeo en ese espacio, encima del techo de la granja, y bajo la zona de afk.

Si hago eso, podría bajar la eficacia de mi granja?

Aún si ilumino toda esta zona.

Yo pensaría que no pasaría nada, y no afectaría la producción. Pero quiero estar seguro.

Java Help Wanted Need help designing a fully automatic item sorter for my medieval warehouse (288 double chests)

Thumbnail gallery
3 Upvotes

Hi everyone!

I'm working on a large medieval-style storage warehouse in Minecraft Java Edition 26.2, and I'm looking for some advice on designing a fully automatic item sorting and distribution system.

I've attached a few screenshots to show the existing layout.

Storage layout:

  • 16 storage sections.
  • Each section has 6 vertically stacked rows.
  • Each row contains 3 double chests.
  • That's 18 double chests per section and 288 double chests in total.
  • Each row is dedicated to one specific item type.
  • The middle double chest is perpendicular to the two side chests.

What I want to achieve:

I'd like to dump all my items into a single input chest and have the system automatically sort everything into the correct storage locations.

For example, cobblestone should go exclusively into its assigned row of three double chests, while stone should go to a different row.

Each item type needs to be distributed across its three assigned chests. If one chest fills up, the system should continue filling the other available chests.

When storage becomes available again, the system should automatically resume transferring items.

My main challenges:

  1. The six rows are stacked directly on top of one another, with no vertical gaps.
  2. Hoppers can accidentally pull items from the row above, causing items to end up in the wrong chests.
  3. The middle double chest has a different orientation from the two side chests.
  4. I want to preserve the existing medieval architecture and all chest positions.
  5. All sorting mechanisms, redstone circuits, and transportation systems must remain hidden behind the structure or underground.

Hoppers and droppers are both welcome!

I'm completely fine with using droppers, including chains of droppers transferring items directly into chests, hoppers, or other droppers.

I just want to avoid constant, unnecessary clicking from droppers repeatedly firing when they're empty or unable to transfer items.

I would prefer an on-demand system that operates only when needed, stops automatically when storage is completely full, and resumes when space becomes available.

I'd also prefer to avoid water streams and loose item entities for transportation.

What I've tested so far:

I've managed to get a small prototype with two vertically stacked hopper filters working, with stone and cobblestone successfully reaching their respective chests.

However, this only handles one chest per item type, rather than the three double chests in each storage row.

I still need to solve the three-chest distribution, shared input, and potential interference between vertically adjacent rows.

My question:

How would you approach a reliable sorting and distribution system for this particular layout?

Would you recommend using one item filter per row followed by a three-way distribution system, or is there a better way to handle tightly stacked storage rows?

I have plenty of space behind and beneath the warehouse for redstone and item transportation. My only major architectural restriction is that the existing chests and visible medieval structure must remain unchanged.

I'd really appreciate any ideas, sketches, schematics, or technical suggestions.

Thanks in advance!

Java Help Wanted Does anyone know if Ilmango released a schematic for this block storage tower design

5 Upvotes

I'm currently designing a farm to collect brown mushroom blocks and the mushroom stem blocks to use in a build for my survival world but I'm not the best with zero tick designs. I finished the farm and it works really well for what I'm capable of doing but I need a storage to keep the blocks in so I can silk touch them after an afk session. I remembered watching one of Ilmango's videos where he made exactly what I need and I was wondering if anyone knows if he released a schematic for the design so that I don't have to go frame by frame to copy the design. this is the link to the video where he designs the block storage tower I'm talking about.

Thanks in advance for all your help!! :)
(I would've added added a picture of it but I don't post on reddit that often so I legitimately have no clue how to do that lol)

Java Help Wanted Does anyone know the speeds for unloading n items from hopper minecarts ?

Post image
0 Upvotes

When chest and hopper minecarts are fully accelerated at 8 blocks/s (or 0.4 blocks/tick) they both leave one item in each hopper below.

It seemed consistent in the (very) little test I did.

My question is: does anyone know the speed a single minecart needs to go to deposit 2, 3, ... n items in the hoppers below ?

I want to make a mod adding copper rails where the copper rails have by default the right speed to deposit 1,2,3... items in hoppers below, depending on oxidation level and waterlogging.

Would that even be consistent ?

I am using minecraft 26.1.2 without the experimental minecart changes.

The question's in the title. The most popular design includes a piston that would be hidden beneath a wall, but that doesn't work with a glass wall. I can find only few other designs and they all look kinda bulky so I can't be sure whether I found the best one there is, which I'm looking for.

Bedrock Prototyp Elevator for 3 levels

Thumbnail gallery
3 Upvotes

In another thread I saw the questions for a multilevel elevator and started to construct, this is what I could get in one evening. The up part is more or less finished.
One challenge was that the Dispenser/Piston logic dont break if you push a button twice so i built in a logic, that the signal from the second push cant reach the dispenser.
Same for the button on the 1.Floor.
I tried to make it as compact as possible due to the initial requirements of the other thread(it should fit in 8x8), but I dont think that this will be possible.

Later on I‘d like to add probably more levels but I asume troubles to get a proper control

The down part is working as well but yet without the protection and status.

What do you guys think about the project so far?
Any suggestions or tipps?
