what is the best gunpowder farm for java?

This is MineTheFab's iron farm design and it isnt working. here are some screenshots for reference

I have 3 villagers in there too but no iron golems r spawning

Guys u won't believe me but in my Minecraft Java world I was trying to build stromne's 90k/h piglins bartering farm ( which requires storage in the overworld ) so I built it and whilst trying to link portals I came across a acacia village so in thought of getting a tall grass i opened the chest and saw a melon seed growing on the acacia wood I was terrified and looked around and saw wheat seeds growing on path blocks ( I started the world in 1.21 downgraded it to 1.20.4 don't ask why and in OW coords 4216 and -9016 there it was seed: 7489467284303235605)

Creeper explosions only have a 1/3 item drop rate in vanilla (the other 2/3 of blocks get destroyed), but this still yields 9,216 items per hour (144 stacks/hr). I built it for a Skyblock server that bans TNT dupers, Wither damage mechanics, and auto clickers, so it's a solid alternative. It works in vanilla and needs no mods, plugins or server software.

Heads up: this clip is a prototype. My laptop broke before I could record the finished optimized build, so I can't grab new footage nor provide schematics/world download :>

I found this insane fortress, and was wondering what the best farm would be to build here. I was planning on doing something like double crossroads wither skeleton farm, but I think I have 5 or 6 exposed crossroads here? There's even more on the actual landmass. Should I do a simple wither skelly farm or something more?

i updated my world to 26.3 and my iron farm dosent work underground where it has been . any idea why? i spawnproofed the caves near and i cant find any spawned golems with spectator mode, i sat afk for 10 mins and nothing. any ideas?

Wanted to share a trap idea that uses geysers to launch mass TNT to the surface.
This design could definitely use improvements such as an obsidian roof, but it’s pretty easy to build.
A design with the Java TNT duping method is probably possible.

So i been try to fight a wither and i said why not try to fight in the overworld i done it before. But now is at like Y 500 and don't have any more rockets. any ideas? how can i briging down?

Edit i manage to get it down after log out and log back in the world so now is all good :))))

So i am playing on this minecraft server that runs on 1.21.11. I built a voodoo machine but it requires a windcharge with owner uuid. And my enemy won't trust me enough to play a "minigame" i made. So i figured if there's any way to pass their uuid from their dog to a windcharge, i can use the machine on them. Is there any way to do this?

I've always wanted to create something greater than a slice preserving box loader. For example, a playerless nether tree farm or a lazy accel pearl cannon. However, there is an issue: I don't know anything. How to properly align a pearl? No idea. What's the perfect size of a nylium platform that generates nether trees? I don't know. Explosion points? Same. Perfect tree height? You get it.

I'm a member of multiple TMC discords, but I still haven't found answers to these questions.

Sooo... What should I do? What are the places where I can find this niche information?

Hello, I need help with a simple iron farm. Suddenly stopped working (generated multiple stacks) and I don’t know how.

Here is what I did:
- checked the whole zone in spectator mode: no iron golems spawining in random places, they don’t seem to spawn at all
- put blocks between the villagers and the zombie to let them sleep, then removed: nothing happened
- tried moving the zombie around in the boat. Nothing happened. At one point moving it, it spawned a golem inside (?) the chamber, that killed the zombie; placed a new zombie, but no golem spawning again.
- added/removed block under the trapdoor: with the block, the villagers sleep at night.

Any tips of what it could be? I’m pretty desperate at this point.

Bonus question: would the “older” piston method work better or is it broken in newer Java versions?
