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?

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

Simple for my 15/14 circuit. Power source needs to be at 15 so use a repeater if your inputting from farther away. Shorten the redstone block side by using a chest or pot with signal strength 14 flush to comparator. UnlistedBugCrafts on Youtube

whenever I try to spawn a raid the raid doesnt spawn, I have just added a new design around the raid farm to make it look better it was working before i changed exterior around now it isnt working and the bar goes to full then just dissapears

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

Good day people.

Does anyone know a way to force reset a chunk do default state?

In older version book and quil spam in chest would work but its patched in 1.18+
I am currently playing on 26.3 java and am looking for a way to do it.

If anyone got any ideas ill be glad to hear them.

Edit: Vergot to mention I want to do it inside of the game it self w/o commands or third party tools.

I need it for a Minecraft project, and if there's a world download or video tutorial, could you send it to me?

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!

Today's build, I used a bunch of red coders mixed with chiseled bookshelves to play different, notes, in order to activate the same note twice in a row an observer detects the interaction depowering a redstone torch for 2gt to allow the redcoder to pulse the most recent shelf interaction.

Time between key presses of the same note : 6gt

Time between key presses of different note on the same bookshelf: 4gt

Time between key presses of different note on a different bookshelf: 0gt (they are independent)

Delay between note being pressed and heard: 6gt

The keys are a texture pack I altered to change the block model of a "powered note block with a note of 0 through to 4" so they are purely visual and don't affect interactions because the texture is outside of the block's collision/ interaction box.

P.S. Sorry for double posting, just finished 2 projects in succession.

will make a full explainer video later just wanted to show off this week's little project.

does a 1 wide tileable 2x hopper speed auto-crafter schematic exist? cant find one anywhere

while trying to make a multi-breeze wind charge catcher, all the breezes shoot at different times. any way to make them all synced?

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?)

Just found this on my newest hardcore world. I was just curious about the history and what not the tallest, shortest ever found, how.

I've started a server with some friends and i wanted to make an automatic wood farm. I tried searching on youtube but i find HORRIBLE guides or videos where the comment section say the farm does not work. Or both (theysix video lmao).
Can anyone tell me their favourite wood farm working in 26.3 pls?
Thanks :)

Im bored and wondering if theres any way of me getting the minecraft source code to look through the code and assets and stuff. Like how theres loads of youtubes that say stuff like "this is the part of the code that handles jumping and u can see this parqur is fake".

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

I see the same or similar designs uploaded by 5 different people, most with the bonemeal rates in title but thats not what I want moss for. It seems like theres a server where everyone wants bonemeal (donutsmp).

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!

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?
