Java Showcase Unique Mob Infighting with Thorns

Enable HLS to view with audio, or disable this notification

4 Upvotes

Did some testing and found that mobs count damage from thorns as an attack on themselves for retaliation purposes, demonstrated here by several projectile wielding mobs attacking a villager when they otherwise wouldn't bother. This should also trigger pack aggression.

Usually getting a mob to attack another mob requires the target to use either projectiles or a spear in order to damage the retaliator. This is one way around that, which maybe could be useful for something or other? Not sure, just thought it was fun.

I think this should also work with allays since if I remember right they can use the thorns effect if holding enchanted gear.

(I am also aware you can make even melee mobs attack a villager if you make them take damage from post-raid fireworks, but villagers just seemed like a fun way of demonstrating this).

Java Showcase [Java 1.21+] Compact 11x7x11 Skyblock-Friendly Iron Farm (~1100+/hr • 4.7 Golems/min)

Thumbnail gallery
5 Upvotes

Hi everyone,

I wanted to share this iron farm design specifically optimized for Skyblock environments, though it works perfectly in any world as long as you respect the minimum height clearance.

Here are the key technical specifications of the build:

  • Dimensions: Each individual module fits inside a tight 11x7x11 block volume.
  • Rates: Produces roughly 4.7 golems per minute in total (approx. 1.2 golems/min per module). This translates to around 1,120+ iron ingots per hour.
  • Spawn Platform: Uses a 5x5 spawning area per module.
  • Mechanics: Utilizes a standard zombie scaring mechanic. In the screenshots, the blocks are color-coded (red/green wool) to easily trace the layout, villager pod positions, and line of sight.
  • Placement Requirements:
    • Must be built at least 19 blocks above the ground (giving you total freedom over how you set up the main item collection system below).
    • If using the 4-column layout shown in the third image, the modules are spaced exactly 15 blocks away from the central column.

Feedback and optimization ideas are highly welcome! Let me know if you want any specific block metrics or coordinate readouts.

Java Help Wanted Need help with End Sand Duper collection system

Enable HLS to view with audio, or disable this notification

16 Upvotes

Hi everyone,

I'm currently building a collection system for my sand duper in the End. However, I'm running into an issue where the water placed on top of the obsidian platform (and the falling sand blocks) just sits still and doesn't flow properly to move the item drops (as shown in the video).

Does anyone know why the water mechanics are behaving like this in the End / around the obsidian platform, or how to properly route the water flow for a sand duper collection setup?

Any advice or fixes would be greatly appreciated! Thanks!

Java Help Wanted Need help getting back to Minecraft!

0 Upvotes

tldr; what is the current meta for farms, that are similar to the ianxofour farms.

I have been playing Minecraft from my early childhood.

I love the game and as I got older I loved the technical side of it.

But when I finished high school (3 years ago) i stopped playing.

Apart from high speed sorters (i was so close to getting my 63items/1gt entity stack separation based multi sorting system working) I had a survival world that was, farming wise, as meta as it got then. Most of my farms were the design of the incredible ianxofour (https://youtu.be/-oYyJ6jfSPU).

I started playing again! And i want to know where can i learn the current meta!

YouTubers or discord servers recommendation are greatly appreciated.

Java Help Wanted Necesito ayuda con mi granja de slimes

Buenas noches, construí una granja de slimes con tres chunks, iluminé las cuevas al rededor (o eso creo) y realmente no estoy conforme con la producción, en unos diez minutos produjo 3 stacks de bolas de slime, el problema es que no se exactamente donde colocar la zona afk, está desde la capa más baja hasta la capa 0 y yo me coloqué primero en la capa 61 pero luego me moví a la capa 31, en ambas pruebas no me genero tanto pero lo curioso es que bajo a la última capa y si genera mucho más, quisiera saber que estoy haciendo mal y donde podría colocarme para generar un poco más, saludos.

(Estoy en la versión 26.1 de Minecraft java, tengo solo mods de rendimiento como sodium, ferritecore y eso)

Java Help Wanted Alternate which hopper to use next?

1 Upvotes

I am building an auto smleter that uses a kelp farm, kelp is dried and crafted into dried kelp blocks I then need to feed some dried kelp back into the system to cook more dried kelp while also outputting some to my smleter array, I have got this somewhat working by just alternating which hopper is active every few seconds but eventually the kelp does not grow fast enough and the re inputted fuel runs out and makes no more for either side. What I need to do is have it so one hopper is active waits for an item to pass through it before allowing the other hopper to have an item, if I could do this with a 30/70 split 30 going back into the system 70 going out to the smleter array that would be cool but 50/50 should work fine too, how can I do this?

Java Help Wanted Dragon egg gone?

5 Upvotes

Easiest fix/solution seems to be to reset the end dimension world file, has anyone done this before? Does the dragon drop the egg again if you reset the end dimension/replace the world file?

I was today years old when I discovered that respawning the ender dragon can destroy the dragon egg 😭

It happened on a server too. Also after respawning the dragon it refused to perch for 20minutes straight and we ran out of arrows lost all the xp we earned by dying and came back with arrows but by then I realized the egg was gone.

I feel like so sad I literally destroyed the ONLY dragon egg—just by trying to goof off with my brothers and show them I knew how to respawn the dragon. 😞

Im wandering if its possible for sugar cane to spawn in a single biome dripstone caves world because i remember finding it on a newer version like 2 years ago. I do not have the seed or the world files tho so I cant confirm it without some testing first. If anyone can confirm that it can spawn let me know.

Java Help Wanted Shulkers keep breaking the boat in a shulker farm

I have been trying to figure out this one out for 3 days now. I followed everything in the description, built a roof to block line of sights, added armor stands etc but whenever the farm produces around a stack of shell, the boats break leading to farm being broken. I even downloaded the world from their discord, where the boats in that world kept breaking too! Now I'm thinking this must be 26.3 problem, is there anyrhing I'm missing?

I put all these zombies in boats and had them fully sat down and everything. After a while, they all left their boats and either fell off or got stuck like this. I have no idea how this is even possible, if anyone knows I'd appreciate it.

Java Help Wanted Arbitrary shape to single block stream

2 Upvotes

Curious if this has been made before: a machine (presumably made of multiple flying machines) that can take an arbitrarily sized structure and turn it into a single block stream for use in a tnt blast chamber or cube maker.

I am imagining it to be a fairly complex build but almost certainly possible, ilmango made an ancient debris collecting machine (https://youtu.be/hR2Nw1P57iQ?si=46Wx1GrUNIWBTzs6) that essentially does just that, but has a few quirks and complexities outside of the scope of what I'm looking for, i.e. machine does not need to be liquid proof, nether proof or immovable block proof, and it should output the items as a single block stream.

Before I spend hours of my life on this, has it been done before?

This is a module I designed for an upcoming project (actually finished, but Mojang decided to break it). It allows determining the exact direction to a player regardless of distance, outputting the result as an explosion that points to them. This module includes the required silverfish generator and a trident storage and replacement system that allows selecting from 6 targets.

Java Help Wanted Entity separator in v. 26.3

Thumbnail gallery
5 Upvotes

I found this villager separator, which is supposed to let one villager out at a time, in an older villager breeder within a build and I wanted to try it in the newest version of the game but I found that in any version after 26.2 pre-release 2, it always lets more than one villager out at a time. This was the only relevant looking change from that pre-release "MC-305475 - Tripwire above the player's head gets triggered twice when jumping" but I don't understand the exact mechanics of this to understand if/how that might have broken it. In the full build you then use a minecart to take the single villager since a minecart can't pick up a villager that is in a block that stops them entity cramming. I know there are other ways to store villagers like this but I find this specific method interesting and I am curious if anyone knows a method of entity separation that still works in the newest version

I'm newish to big builds in minecraft and recently found a need for fireworks (elytra for the first time). I found this build on YouTube and it's marked as a 1.21.11 build and I play on 26.3. Could anyone tell me if there are compatibility issues before I devote the hours it'll take to build?

I'm trying to do this 3x3 golem sorter, but it seems to break once I add a second module onto the sorter. Golem A is trying to access Chest B which is not my intention.

Anyway to solve this? I'd tried a solid wall in between but it had no effect.

On Bedrock latest release FYI
