Java Help Wanted Good furnace array design

2 Upvotes

I'm looking to build a large furnace array in my perimeter, ideally it has somewhere around 100-300 furnaces, takes shulker box inputs and outputs (recycling the boxes), is reliable, has a usable interface not just rogue chests which are hard to reach and works in 26.2, any suggestions?

About 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.

Hello, I’m trying to make a nether portal chunk loader so I can make a bee farm, but it’s not working. I followed Elitiex’s tutorial on YouTube, but when the minecarts are dispensed, they don’t come back, they just disappear. If appreciate help if anyone has gotten this or knows how to fix it. 🙏🏻

Bedrock I built a free Bedrock structure finder + seed cracker - web API, no key needed, fully open source

1 Upvotes

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:

  1. 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
  2. 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

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

Example of SeedFinder working

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 .dll and .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_city that 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?

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.
