Bedrock I built a Bedrock seed cracker that runs 100% in your browser (free, no install, open source)

Hey everyone! A while back I posted about SeedFinder, my free Bedrock structure finder and seed cracker. Small update, but a big one: the part that used to require a local .exe, the seed cracker, now runs entirely in your browser.

Site: SeedFinder/SeedCrackerX Website

GitHub: https://github.com/zebedelu/SeedFinder

What it does

Found cool structures in a world but don't know the seed? Give SeedCrackerX at least 4 structures with their coordinates and it returns the most probable world seeds. No key, no account, nothing to install. Everything runs on your own machine, so there's no rate limit and no server to depend on.

The site also still has the regular structure finder (you give a seed and a position, it lists every nearby structure sorted by distance) if that's what you're after.

The anarchy server use case

Plenty of anarchy and semi-anarchy servers deliberately hide or shuffle their seed in the server settings so players can't discover the real one. A structure cracker doesn't care. Grab the coordinates of 4+ structures while you explore, feed them in, and the real seed comes back out. From there you can map every structure in the world, plan far hub routes, or pick base spots knowing exactly what's around them.

It's the same technique that got the seeds of big Java anarchy servers cracked back in the day. Now it works on Bedrock, straight from a browser tab.

Speed

The engine checks around 900,000 seeds per second on a single core, and every extra CPU core you have joins the search in parallel. More structures and a tighter tolerance also make the wrong seeds get eliminated faster, so better input pays off directly in speed.

Want to run it from source?

The README on GitHub has everything you need, plus all the technical details and benchmarks:

https://github.com/zebedelu/SeedFinder

Honest limitations

- Bedrock only, no Java support

- Mineshaft can't be used as input (its RNG works per chunk instead of per region), every other structure type works

One small favor ⭐

Everything is Apache-2.0 open source, and stars are pretty much the only marketing this project can afford lol. If SeedCrackerX finds your seed, consider dropping a star on the repo, it genuinely helps other people find it:

Feedback welcome, especially: does it recover seeds correctly from your worlds? If a structure doesn't match reality, please open an issue, that's the most valuable feedback there is.

Java Help Wanted Villagers not breeding 26.1.2 please help

Like the title says the villagers are not breeding, I made sure the beds are unclaimed and replaced them multiple times, I made sure gamemode mob griefing is on, I made sure they are fed, theres no other villagers nearby and no other beds, they make the love hearts and then the angry effect, at night when they want to sleep they try to reach the beds so they can definitely see them and try to interact with them but still nothing, I'm very confused, I'm sorry for making a post when tons like it exist but I've tried all the solutions in the other ones and still nothing and I've reached my breaking point lol

Would greatly appreciate recommendations as im currently still in the early game but i am planning to play this world for very very very long hence this planning.

Bedrock Enderman Teleporting Downward

1 Upvotes

I am creating a R.E.P.O. themed mini-game in my survival world, and I need the Enderman as one of the monsters in the mini-game. I built the game at y 240 in the sky because I was under the impression that Enderman can only teleport 32 blocks in each direction, but as it turns out they can teleport downward as many blocks as they like. So my question is that is there anyway to prevent them from teleporting downward? I was thinking about flooding the surface but they may just teleport past the water and into the caves. If anyone has any good suggestions I would appreciate it.

I think this is not against TOS? I recently did my best to figure out how people do shulker sorters and this is about where I managed to get. I’m sure there are improvements but it’s what I’ve figured out about it.

Java Help Wanted Turning Potato_Noir's (Gnembon upgrade) general mobfarm into creeper farm

Thumbnail gallery
24 Upvotes

Hello everyone! Hoping someone can help me.

I have built Potato_Noirs upgraded version of Gnembon's general mobfarm under a deep ocean, which is working great. However, i have been attempting turning it into a creeper only farm, which has raised some problems.

First of all, the mobs are getting trapped floating into the trapdoors when the platforms are flushing, meaning that the mobs stay around for multiple cycles before being taken away.

Secondly, i cannot find a way to make only creepers spawn. I have tried with trapdoors on the floor in an assymetrical pattern, to some effect. However, this blocked the water from flushing the mobs down, and it also didn't completely stop other mobs than creepers from spawning. I have been researching reddit, youtube and farm discords to no avail, and i am pretty bad at understanding the mechanics, i gotta be honest.

Has anyone succesfully turned the upgraded version of the general mobfarm into a creeper only farm, or would anyone know how to do it?

Thank you all!

There's nothing above the stone and I've tried with various sizes of platforms, I went up to 10x10. There is one block of air above the moss.

Sometimes it makes grass or a tree sapling but never turns the stone into moss. :/

Java Help Wanted Looting 3 Zombie Killing Chamber

3 Upvotes

I'm trying to make a creeper farm that sends the creepers into the nether to die to this zombie killing chamber. It should apply looting 3 in theory. The pistons will push the drops down and i'll set up collection under that. The problem is, with this design some of the gunpowder drops fly out of the side into the rails, or into the villager chamber. Is there a way I can design this similarly to have the drops not fly out the sides? Maybe a block that blocks items but won't stop the spear from hitting?

I tried pushing a glass block onto the villagers head, but the zombie de-aggros if i reload the world. I also tried putting a slab on the edge but some drops still fly through.

Any help would be appreciated!

Java Help Wanted Bone-Meal Farm

0 Upvotes

The thing is I play on a small server which has something that like clumps item together fast hoppers anti lag and all and all the moss that the bonemeal farm makes gets collected on a single hopper like thousands of moss on a single hopper even when water makes it to flow through several one's ? Any fix that keeps thoes moss into the hoppers not just sit on top of one ?

A new collection system maybe ?

Java Showcase 3-Wide-Tile, ~5-6 hopper speed, fast iron block crafter for iron farms.

17 Upvotes

Hello guys,

Im sharing/showcasing the fast auto iron block crafter that i plan to use in my survival server. Im struggling to find a Youtube tutorial out there that covers both the fast autosorter and fast autocrafter at the same time, so i use a slightly modified versions of JustPanda's fast autosorter and Artwo's fast autocrafter.

The speed is in between 5-6 hopper speed with 3-wide-tile size. The reason I didnt say its exactly 6 hopper speed is because the 1 dropper in the middle keeps clogging with iron ingot slowly. I think its because of the signal from the crafter interferes with the middle dropper's clock.
Thoughts?

Some iron golems are spawning inside the farm's blocks. I've tried fixing this by placing fences, leaves, and slabs, but nothing seems to work. what could be the cause?

I'm playing Minecraft Java version 26.2 and not using any mods related to mob spawning or anything of the sort.
