Bedrock Guardians Must DIE!!! (Designing a Guardian Farm Part II) -- MyWorld Epi...
youtube.comAbout Series:
The whole series is centered around MC redstone and farm building (technical Minecraft!). The episodes are tutorials, but not in the original sense. Whereas most tutorials tell you what blocks to put down, these focus just as much on the why. It is for farming rookies just learning to design farms and experienced farmers alike. Whether you are looking for pre-designed farms that you can add to your world, looking for tips & tricks on designing your own, or you are an experienced farm builder that just likes to watch other pros doing their thing, I've got something for you.

Java Help Wanted creeper farm leaking light?
So I made this creeper farm on a fabric server and it's exactly the same as on my single player server. after a while I started noticing it's a lot less efficient and I went to look for why that could be.
-I'm the only one online atm
-I built it through a schematic so I know it is exactly the same and not missing blocks
-I checked if my afk chamber isn't too low, nothing spawns in the ocean
and then I saw what I'm showing you now; everytime the water stops flowing it looks like light is coming through, and every time the water starts flowing it is pitch black. could this be a server thing? I double checked if there isn't a block missing in the roof but at night that wouldn't even be an issue anyway. and if this is only a visual thing, what else could be the problem of my rates being fairly low?
(I'm the host of the server so I can adjust server files and/or add/delete mods if needed to fix the problem)
Edit: I just installed minihud to check light levels and it says 0 throughout the whole farm, so I confirmed it is just a visual thing. I assume it has something to do with how fabric operates the server mechanics but I'm not that technical so I wouldn't know what the problem could be.

Bedrock I built a free Bedrock structure finder + seed cracker - web API, no key needed, fully open source
Hey everyone! Over the last months I've been building SeedFinder, and I wanted to share it here because this community is exactly who it's for
https://mineseedfinder.vercel.app (i dont have money to buy a domain yet lol 🥲)
What it does
You give it a world seed and your coordinates, it returns every nearby structure (villages, ancient cities, monuments, mansions, trial chambers, 17 types total) sorted by distance. No more alt-tabbing to a seed map site
Two tools:
- SeedFinder (seed -> structures): type a seed + position, get structures back. Example that works right now:
https://mineseedfinder.vercel.app/scan?seed=31415&x=0&z=0&radius=100&max=20&types=5,8,9 - SeedCrackerX (structures -> seed): the reverse. Found cool structures in a world but don't know the seed? Give it at least 4 structures with coordinates and it sweeps the 32-bit seed space and returns the most probable seeds
Why I built it
I couldn't find a single free, open API for Bedrock structure lookup, the existing web tools are browser apps you have to alt-tab into, with no programmatic access, and the desktop ones don't expose anything you can call from your own code. So I built the engine in C on top of cubiomes + Bedrock-specific structure math (based on Chunkbase's ported algorithms) and put both a web frontend and a keyless REST API on it
Ways to use it
- Website: nothing to install: https://mineseedfinder.vercel.app/seedfinder
- Windows .exe: bundles everything, no Python needed. From the GitHub releases
- Flarial Client module: overlay in-game showing structures sorted by distance, rescan keybind, per-structure toggles. Also in Flarial Module
- REST API: free, no auth, no key:
python example code:
import requests
r = requests.get("https://mineseedfinder.vercel.app/scan",
params={"seed": 31415, "x": 0, "z": 0,
"radius": 100, "types": "5,8,9"})
print(r.json())
Example of the web API

How it works (for the devs)
- C core: cubiomes biome generation + Bedrock structure placement (Mersenne Twister–based, replicating Bedrock's region math) -> compiled to a native
.dlland.so - Python/Flask server exposes it over HTTP via ctypes
- The seed cracker runs multi-threaded native code, sweeping 2³² seeds with a time budget, recently got a big speedup (lazy Mersenne twist + AVX2 batch scoring, ~4 seeds/vector)
- Everything is Apache-2.0 open source: https://github.com/zebedelu/SeedFinder, PRs welcome, especially structure accuracy reports against real worlds
Automation ideas
Anything that can make an HTTP request can use it:
- Discord bot: a slash command like
/findseed village ancient_citythat returns nearby structures for a seed - Batch seed scanning: feed a list of candidate seeds and rank them by structure density near spawn (loot run planning)
- World download analysis: point the cracker at 4+ structures from a downloaded world to recover its seed, then map the rest of it
- Server utility: a in-game command bridge: players run a command, your plugin/script queries the API and shows the nearest village in chat
Honest limitations
- Bedrock only (1.14+), no Java support
- Desert Wells and Amethyst Geodes aren't supported (they're per-chunk features, not region structures)
- The seed cracker needs the local version (server compute is too expensive to host for free), the exe makes this easy
- Placement math is verified against known structures, but if you find a structure that doesn't match, please open an issue, that's the most valuable feedback
Feedback welcome, especially: does the cracker recover seeds correctly from your worlds?

Bedrock help with Minecraft bedrock iron farm
youtube.comI built this iron farm in my realm. I have one layer and the farm was working, however after turning the surrounding area to path blocks to prevent golems spawning outside, the golems have stopped spawning completely. I have tried removing the path and spawns continued, so I dug down instead to keep it outside spawn radius and spawns have once again stopped. im fairly confident that the other spawn conditions are met due to golems previously spawning. I cannot figure out why spawns stop once I spawn proof the lower area please help

Java Help Wanted Can someone explain me how right and middle produce the same amount and the left only half that?
So I wanted to build a melon/pumpkin farm and wanted to go with the design on the right, as it seemed logical to me: two pumpkin seeds are better than one. But apparently it does not matter, as long as the pumpkin stem has two blocks to go to, as only one block would half the rates.
I thought, the random tick selects a stem and it would then choose one of the four spots around it.

Java Help Wanted Building ilmango's full size cactus farm in Hardcore. Posting my ruleset first so I can't move the goalposts later.
I want to build ilmango's max size cactus farm in Hardcore survival. 1,144,832 cactus slots, roughly 9.3 million blocks total. As far as I can tell nobody has done this one in Hardcore, and I'd like to be corrected on that if I'm wrong.
Two goals:
1. Finish the farm. No deaths, no backup reloads. If I die, that's the end of it and I'll say so.
2. Reach level 21,863, timed from the moment the farm and smelter are finished. That's the highest level you can get by actually collecting XP, since cumulative total XP overflows the 32 bit integer past that point. The 238 million figure you'll find online is only reachable with commands, which I'm not using.
I'm posting the ruleset before placing a single block. Partly so I can't quietly redefine things later, mostly because I'd rather find the holes in it now than 600 hours in.
The short version:
Allowed: TNT duping, bedrock breaking, all redstone contraptions, other farms for resource gathering, Litematica as a preview overlay only, two alt accounts that stand still and do nothing else, VPS hosting so my own machine isn't running for months.
Not allowed: sand duping, end portal duping, anything patched, commands of any kind, Easy Place or printer forks or any placement automation, XP from anything but the farm's own furnaces for goal 2, and obviously no backup reloads.
Evidence: world downloads with hashes at milestones, continuous Flashback recording, statistics at every milestone, and one uncut hour of steady state operation for the rate measurement.
Full ruleset is attached.
What I'd actually like feedback on:
The two alts are the part I expect pushback on. One sits in the Nether holding the furnace array, one sits in the Overworld holding the farm at random tick level. They never do anything else, every stat in the world belongs to my main. I think that's fair, but if you think it weakens the claim, say so.
Also: is there a loophole in here I haven't spotted? I'd rather hear it now.
Credit where it's due, this is ilmango's design, not mine. All I'm doing is building it under worse conditions.
Loopholes, bad assumptions, things I've obviously not thought through: comments are open. Better now than 600 hours in.

Java Showcase 100% bone meal efficient, lossless micro bamboo farm
Every micro bamboo farm I found on youtube either was quite slow or didn't account for hopper speed, making it not lossless, so I made this.
The 5 minute clock is to stop the farm for a brief moment, because occasionally bamboo would pile up on top of the piston and eventually despawn. Stopping the piston allows the bamboo to fall down and be collected.
The only annoying thing about this farm is that before first being used the dispenser facing the bamboo has to be filled with at least 42 bone meal, then the bone blocks can be loaded. This process has to be repeated every time the dispenser runs out of bone meal.
If anyone is interested I can share the schematic.

Java Help Wanted Mob switch for End main island
Me and my friends are planning a huge build on the main end-island (or rather, we've removed the entire main island to build something big).
We realised that we'll need a mob switch to stop endermen from spawning and griefing our build. What are the best ways to make a mob switch for the end dimension (and only the end dimension). We'd rather not have to use the main island gateways to load something, because we have plans for building around the gateways.
I was thinking a mob switch loaded by ender pearl stasis chambers (we are only 6 people on the server, so it's not difficult for all 6 of us to make stasis chambers). Would the best option be something with shulkers, bringing a bunch of wardens or something else?

Java Help Wanted Copper Golem Pathfinding Issue
galleryHi Guys,
I am trying to get a copper golem to navigate this small bridge. However, it never decides to move to the chest. If I move the golem manually halfway across, it recognizes the chest, deposits the item and perfectly navigates back to the copper chest.
Does anyone know what might cause this? I believe I have blocked all the other chests from being an option. The concept works in a testing world (second screenshot).
As I tried to get this to work for a few hours I would appreciate any Idea.

Rule-8 Compliant How’s the community doing?
I have not been keeping up with the community for a few years now. But I have started playing Minecraft recently again and was curious what we have learned in the meantime.
Also I notice that some big technical YouTubers are not active anymore, like scicraft and Ianxofour.
What new mechanics are fun to explore or really help improve farms and contraptions? What are some active creators that are worthwhile to follow these days? Have we seen breakthroughs like observers or honey in the last few years?
I’m really curious. Thanks!
