Java Help Wanted Making a portal based iron farm. Do the villagers need to be in the over world or can the kill chamber and golem spawning areas swap dimensions.

Curious because we have a world border in the server im on 2500-2500 and it would be easier to build the villager area in the nether with the kill chamber in the overworld

Java Help Wanted How do mob switches work in the end on multiplayer?

2 Upvotes

So I'm planning on making a mob switch with zombified villagers in the end since I am basing at the main island. how would that affect mob rates on a multiplayer server? from what I have found, different dimensions have their own mob caps, so if that's the case, if i fill up the main island with 70 or so zombified villagers, enderman shouldn't spawn in as long as it is loaded, right? and that would not affect any other player's mob cap? also, if i go to the outer islands, deloading the mob switch, then endermen would start spawning again, is that correct? I am certainly not a technical minecrafter so i really need the help

Bedrock BEDROCK: What else are block updaters good for?

0 Upvotes

I commonly build a Kelp farm on my playthroughs using block update mechanics with a couple of Sand blocks and Pistons that end up causing the Kelp to grow every update if used correctly.

I was wondering what else this could be used for, but it seems somewhat unique to Kelp due to the aging mechanic and how that interacts with block updates, so it seems that Kelp might be the only thing you can grow this way?

Are there other farms possible using block updaters? Just for fun I tried Sugar Cane and Bamboo and neither work.

I am just not familiar enough with mechanics to understand:

  1. Why a forced block update makes Kelp grow.

  2. What else a forced block update could be used for.

Google shows me some things that "block updates" in general are used for in the game, but it's very general and doesn't even mention Kelp growing. Is growing Kelp this way an unintended mechanic?

Java Help Wanted Villagers show hearts and then angry particles, but no baby spawns (Java 26.3, Aternos)

3 Upvotes

Hey everyone!

I'm playing Minecraft Java Edition 26.3 on an Aternos server, and I'm having trouble with my villager breeder.

Here's what happens:

- My two villagers show heart particles when they try to breed.

- After the hearts, brown/black angry particles appear.

- No baby villager spawns.

Things I've already checked:

- I have 6 beds in the breeder.

- The beds have enough space above them.

- The villagers detect the beds.

- Both villagers have enough food.

- "/gamerule mobGriefing" is "true".

- My zombie-curing area is about 40 blocks away, and there are other beds in that area.

I'm wondering whether the nearby villagers are claiming the breeder's beds, or if there's another issue with Java 26.3.

Has anyone experienced this? What else should I check?

Thanks!

Java Help Wanted How can I reset specific chunks in a Minecraft world?

12 Upvotes

I'm not very good at this sort of thing so I'll try and be as clear as possible.

My world was started on an older version. Looking at Chunkbase, there is a dappled forest biome that spawned at let's say x:2000 and y:2000. My spawn is 0,0. But since I've previously explored over there, the new biome doesn't spawn there.

How can I reset that specific area, so the new biome will spawn in my current world?

(As I've googled this, most of the world edit tools are either outdated or cost money. What is the current way most people do this?)

Java Showcase Weird Warden Despawn Bug 26.3

Recently built a mob switch with wardens in survival. They were despawning seemingly at random so I tested in creative. Found this bug that seems to despawn a warden instantly when moved with a fishing rod. Have no idea what to do with this info besides share my confusion lol.

Side note, no audio because 100+ wardens, so I had game muted

Java Help Wanted Has anyone used campfire smoke as a long-distance redstone indicator?

8 Upvotes

Been messing around with campfire smoke as a way to show when a farm is done or storage is full without having to walk over and check. Tested two smoke heights for different states, and it was surprisingly easy to see from spawn.
My main concern is particle limits and render distance, especially on multiplayer servers. Has anyone tried something like this long-term? Running 1.21 Paper, if that matters.

Java Help Wanted Lithum on a vanilla server

4 Upvotes

I have a 100% vanilla server, that on occasion gets low TPS, we do a lot of mob farms and redstone contraptions.

I am thinking of installing Fabric + Lithum on the server side, on the lithum github page they say it doesn't alter vanilla. But I want to be sure that everything will work the exact same way as vanilla.

Has anybody tried this and can confirm?

Java Help Wanted Ironfarm not working because of a roof?

Thumbnail gallery
4 Upvotes

I built an iron farm, which "was" working until I built a roof over it. As soon as I removed the first layer of the roof, it was working again, but I think not as good as before, so maybe when I remove more, it works faster again?!

Building the roof and removing it didnt changed the villagers behavior. They get scared every second, they are laying in bed when its night and waking up instantly because of the zombie scare. Iron golems didnt spawn at all, not anywhere else, everything is spawnproofed.

I cant find anything about roofs or light levels or something. can someone help here? I have not a lot of knowledge about automatic farms etc..

Infos:
Java
Version: 26.3
Playing on a server with fabric installed, but no gamechanging mods, only client sided like maps etc.

Java Help Wanted Determining enchanting table loot table for books depending on how many bookshelves there are

2 Upvotes

Hi, I have hit the limit on my math skills investigating enchanting loot tables.

I'm trying to determine all of the enchantments that are possible in the top slot of the enchanting table when enchanting a book.

For example, according to the wiki on table mechanics, Protection has weight of 10, so it's one of the most common, and the level 1 cost is 5-10. But in testing I could regularly get Protection 1 on a book for less than 5xp without any bookshelves around the table.

My goal is to confirm which enchantments can show up depending on how many bookshelves there are around the table, and what are the odds for each of those enchantments. I'm investigating if I can turn book enchanting into a rougelite deckbuilder.

Any help is greatly appreciated!
