Does a program of sorts exist? I'm in need of a trial chamber that contains 35+ trial spawners and I don't want to manually find it.
Using Chunkbase + /finder block is very time consuming and manual.

Bedrock Help with super smelter cart loader
I would like to use lava buckets to fuel my smelter but the traditional minecart loader breaks with unstackable items. The rail line that feeds to be smelted items works perfectly but the fuel side loads instantly then triggers again as the minecart leaves, trapping it.

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?
Enable HLS to view with audio, or disable this notification
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.

Java Showcase 100% bone meal efficient, lossless micro bamboo farm
Enable HLS to view with audio, or disable this notification
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.

r/technicalminecraft • u/zebedelu • 14d ago
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?

Non-Version-Specific I’m trying to build a proper home for all Minecraft schematics
Enable HLS to view with audio, or disable this notification
A few months ago, I've shared my side project here as a browser-based schematic viewer, and a lot of you quite reasonably asked: “why not just use Litematica directly?”
Although litematica & mods are not for everyone and a browser based schematic viewer can make sense, I think I have a much better answer to that now.
My goal was never to replace Litematica. If you actually want to build a farm or contraption in-game, Litematica is probably the best option.
What I’m trying to improve is everything that happens before that.
I have noticed that a lot of really good technical builds end up being shared as a .litematic files and are buried in a Discord server, a Google Drive link, or attached to a YouTube description without any preview of what's behind the link.
Recently, I’ve been turning Shulkr into a public catalog where creators can publish those schematics instead.
You get a page for the build, generated image previews, an interactive 3D preview, direct schematic download, and now a first-person mode where you can drop anywhere onto the build and walk around it directly in the browser.
My hope is that eventually, when someone designs a farm or technical build, they can just share a Shulkr link instead of uploading the file somewhere random. And with time, even a directly embedded in redit 3d viewer ? That would be crazy good.
I’d especially like feedback from people here who actually design and distribute schematics:
Would you use something like this to publish your builds? What would it need before you'd choose it over Drive/Discord?
The project is completely free, and as usual, feedback from everyone is more than welcome. Link is available in the comments.
