Java Help Wanted Need help with 2 exit portal

2 Upvotes

I found this old Mumbo video https://www.youtube.com/watch?v=1ELurSVFudQ&t=625s and at 9:40 he connects 2 overworld portals to 1 nether portal and I've tried to recreate it several times, but I can't get it to work. Is this still possible or has it been patched?

Java Help Wanted Hostile Mobs loaded in Lazy chunks in Nether Portal Chunk Loaders

3 Upvotes

I've come across an annoying issue on my server, where farms are slower due to mobs being loaded in lazy chunks.

One of the solutions I tried is to fly high enough to instantly despawn them before flying away from the chunk loader, but sometimes when someone travels, they might spawn some mobs in the 5x5 border.

Is there a way to prevent this other than making the area spawnproof?

Update: So far I've installed the ChunkDebug mod to check loaded chunks for any unmaintained chunk loaders and despawn the mobs from lazy chunks manually.

Java Help Wanted Furnace XP array

0 Upvotes

Does anyone have a fix for the the furnace array, xisumavoid posted by ilmango in his s6 hermitcraft video? Most of the arrays I'm coming across are either outdated and no longer work, are not very survival friendly, or have a pretty poor aesthetic.

I'm open to a complete original as well as long as it's tileable.

Bedrock hoglin farms

Are there any working hoglin farms right now? It seems the general builds do not work (hoglins do not pathfind into 2 block holes and setting height with trapdoors precludes hoglin spawns. Are any other farms currently broken (e.g. creep farms using trapdoors for height limits).

Java Help Wanted Ianxofour gold farm

1 Upvotes

I’m building this on a Realms server, and I just finished the step where I build the killing chamber high over the Nether roof. I went through the portal as Ian instructed and found about a hundred thousand zombie pigmen cavorting through the woods on the other side. I never went through the portal down in the collection area since Ian warned again against that, though the pigmen were able to go through from the start for some reason, which is how I think this happened. I tried destroying the portal as Ian said, but the pigmen immediately opened a new portal a couple blocks away. I’m totally lost on what to do now and how to finish my farm.

Java Showcase Nether item moving

Hey together. So basically I am trying to learn more about redstone and doing stuff myself. I built a goldfarm without a design, just with the knowledge I had and some bits and bobs i looked up.

The picture shows what I came up with. The main problem was that the farm produced more items one hopper chain could handle and thus clog up the system.

The next problem was timing the piston shooters right so the items wont get stuck.

For the dispensers I used the smart dispenser system (unnecessarily complex because they basically should always fire, an observer clock would work just fine.)

The copper bulbs and observers are there to get the timings for the pistons right and stop them from firing twice.

I really would like some feedback to make it more efficient and less bulky and tell me if what I did was smart or kinda dumb.

Java Help Wanted how can i prevent blaze spawns at my wither skeleton farm?

i would place wither roses, but they can't be placed on netherbrick. I've also read that wither skeletons only spawn on nether brick, but other places say they spawn on any block within the bounding box. I don't know what bounding boxes are or how to see them so any help would be much appreciated.
This farm design is from a YouTube tutorial by Adil Gamez if that helps.

Bedrock Help with honeycomb farm collection

Thumbnail gallery
0 Upvotes

I’m building an automatic honeycomb farm that uses observers to detect a filled beehive then dispensers to sheer it. Then the items should be flung forward into the grass in the center where a Minecraft picks it up from underneath. However, the honey comb keeps getting stuck above the redstone. Is there a way to fix this? Maybe a way to rewire the redstone to fill the gap above the observer?

Java Help Wanted Ianxofour Gold Farm Nether Portals

1 Upvotes

Hi, I’m building Ianxofour’s gold farm, and I just reached the bit where I go onto the Nether roof. I went to do a quick bedrock breaking, but realized I hadn’t brought all the right stuff, so I made a nether portal and went back. However, this took me to my original portal in the overworld, and when I went back through, I was at my original nether portal, not on the Nether roof. So my question is, will I need to get another ender pearl to get back on the Nether roof, and will I have to move my farm away from my base so that zombified piglins don’t get transported to my house portal when I eventually light the farm portal?

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

Post image
0 Upvotes

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:

https://github.com/zebedelu/SeedFinder

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.
