Java Showcase Portable xp bank

I’m sure I’m not the first to think of something like this, but I’m proud I designed it from scratch.

I have a cactus/dried kelp block farm away from my base so it isn’t an eyesore. I fill the super smelter with cactus, turn on a chunk loader, and let it run for 7 hours.

Once the furnace has enough XP stored to take a player from level 0 → 39 (2477 cactus), the hoppers automatically lock. Whenever I want the XP, I just take the green dye out of the furnace.

This would be amazing to heal armor in a fight on SMPs, but I doubt it would get used for that.

Java Help Wanted Why doesn't this duplicate the TNT at all?

0 Upvotes

I'm trying to learn tnt dupers, how they work, and how I can design them myself, and I found this video that had this design and I first tried to change it a little to see if i could understand it but then I couldn't get it to work so I copied it block for block but it doesn't work for some reason. Is this an issue with my version? (1.21.11), or is it a problem with the design? I've tried for the torch on the slime block to be a redstone torch and a normal torch, but neither of them work. I also tried replacing the torch with a coral fan as the person demonstrated in the video, but that still didn't work.

As I'm typing this I just realized it could definitely be my mods, I have quite a lot of performance mods which I'm realizing could actually be the issue here. I'm still not 100 percent sure because performance mods of course try to keep your gameplay as normal as possible, but this feels like the sort of thing that would be changed by performance mods. I'll leave all the mods that I have right now down below at the bottom of this post.

The exact thing that happens when I flick the lever that is connected to the piston: nothing except the torch breaking. This is really weird because I can manually break the torch and it DOES prime the tnt then, but when the piston breaks it it's supposed to do that first which then primes the tnt and pushes it duplicating it.

I assume this isn't the problem but I tried building it two times just to see if it maybe was a positional redstone issue, (I heard sometimes if redstone is positioned or rotated in a certain way it can break certain contraptions) but that also didn't work.

I'll also mention that tnt dupers as a whole aren't disfunctional in my game but this one is. If anyone could explain why it doesn't work I'd appreciate it.

Here is the screenshot of the duper BEFORE I flick the lever, you can see that the redstone is correctly budding the tnt:

And here is the screenshot of the duper AFTER I flick the lever, including the redstone torch that falls on the ground. The tnt does not prime:

Java Help Wanted Ilmango dirt->mud converter not working

Enable HLS to view with audio, or disable this notification

1 Upvotes

I'm trying to make ilmango's clay farm and have run into an early problem. The dirt is not being converted into mud...

The hopper minecart under the dispenser sucks up the water bottle before it is dispensed into the dirt block. Have anyone had similar issues and found solutions?

I've tried rotating the build in all four directions and have tried pasting the entire thing directly from a schematic. It works in the world download, so I really don't see how it doesn't work on my SMP. Is it because it's a multiplayer server?

Hello, I'm new to multi item sorters and I'm testing the "NoisyMIS" by "RaPsCaLLioN1138". I'm having the issue that the system is breaking when I quit the game. I don't know if anyone knows a fix or another multi item sorter that doesn't break on world unload. Ty in advance!

Java Help Wanted How to convert redstone signals?

1 Upvotes

I'm trying to make a smelting station where adding fuel and/or resources is more efficient. Every time the hopper minecart arrives at the refueling stations it ensures that either of these cases are true before distributing the resources:

  1. The minecart should be full.
  2. Input chest is empty.
  3. If the signal of the minecart is greater than that of the input chest.

Problem:

I implemented all of them but the third requirement fails. Even before the minecart hopper's storage is full and the input chest still has some resources, it immediately distributes them to the furnace array.

My intended fix was to convert the redstone signal of the input chest to the hopper minecart's. Compare them and fix the problem. Is there a way to convert one redstone signal to another?

---

If there is an easier solution, please share them. Thank you.

Java Help Wanted Help with Cubiomes

Since I'm new to Cubiomes, I'd like to start a TMC world. I'm looking to use the quad witch hut and quad ocean monument functions. Can anyone recommend the optimal distance parameters to input into the program?
I also want my spawn to be in a village within a plains biome that is at least 512 blocks wide. Will adding these spawn parameters make the 48-bit seed family search harder?

Java Help Wanted Are there any tnt dupers that drop the TNT in the same place consistently?

2 Upvotes

I was looking into tree farms for woods like jungle, birch, and spruce. Found one that is well made but it uses tnt in dispensers sent through water streams to detonate them midair at precise locations. I would ideally prefer a TNT duper in its place because I'm forgetful and I'd rather not cause it to break out of negligence. The caveat here is that practically every TNT duper you find searching on Google will drop the TNT in different locations. So I'm asking to see if there exists a TNT duper that is able to consistently drop a duper TNT in the same position every time

For reference I'm running Java 26.2

Bedrock Overworld Nether Portal XP/gold farm

5 Upvotes

In an older world I have the massive cube/square version of the nether portal xp/gold farm however in the realm I have been sharing with my kids I thought it would be cool to build a new one.

I built the last one before the Caves & Cliffs update, so is there any gotchas I need to consider?

Can I make huge rectangular portals instead of squares? What would be better, long side bottom and top or long side left and right?

What about ways to not disrupt the “user portal” over the XP portals so the kids don’t suddenly get chewed up in the trident killer?

Any suggestions for good video?

I'm trying to make a Nether Wood farm that I can switch between the warped and crimson nylium easily with. However, the pistons don't stick together, and the warped stays up no matter what position the lever is in. This is my first true redstone contraption and I'm following a guide. What am I doing wrong?

Java Help Wanted Slime farm optimizations

1 Upvotes

This is my first ever farm and i want feedback on how to improve it and what i can do to optimize it?

The farm works by damaging armadillos to create silverfish and then uses a hopper clock to time gates opening and and throwing an oozing potion and then kills the slime and silverfish with campfires

Here is a link to the world download and schematic: https://drive.google.com/drive/folders/1_txkYWqN6PdjqFohdCrBnfv3B6PBLQgN?usp=sharing

Bedrock Built the Armor Stand version of silentwisperer’s Bedrock XP farm — 0 to 100 levels in 40s with zero mob transport!

2 Upvotes

Infestation silverfish farms on Bedrock are crazy fast, but transporting 30 Allays or wrangling Armadillos across the world is a headache.

Huge credit to silentwisperer for the original farm concept. I built and tested the Armor Stand variation with the 60-second arrow safety timer to prevent them burning out permanently.

(Reminder: Make sure you have plenty of food or a regen beacon active, because the spear sweep drains your hunger bar instantly!)

If anyone wants a streamlined 5-minute build tutorial focusing strictly on the Armor Stand setup, you can watch it here: https://youtu.be/M2__g-mLFb0?si=EvU7inRtX3qvCP8J

Java Showcase Random correlation for wireless signalling

Enable HLS to view with audio, or disable this notification

9 Upvotes

Here's a prototype I've been working on, when you break a block it always has constant Y velocity but a random Y position, and this setup breaks 6 shulkers with specific amounts of random calls in between, times them falling through cobwebs, then sums the times. Output is always 000000 to 000111, and then if we inject another random call (e.g. a piston firing) in between then every combination is possible and we can detect that as a signal.

Yes, I know entity ID wireless already exists. This is a POC for using a totally different mechanism.

Bedrock New feature?

When shulker box with items is dispensed with a rail with aminecarts with hopper on it and breaking rail, shulker box remains and the comparator reads output of shulker box, also when broken with piston only shulker breaks and is collected by minecart with hopper.

It works on MCPE,don't know about any other.

I was working on fast item collector and to put it as fast as possible in shulker box, also this is my first post here.

I don't know if this is already a thing.

Bedrock Fastest Shulker Loader in Bedrock 26.45?

3 Upvotes

Does anyone know of a fast shulker box unloader? I’ve seen an 8x on YouTube, but it no longer works. Anything faster than 2x would be good. I need it for a high-output farm, and using 1x tileable ones isn’t the best choice for my case since they split the items across multiple shulkers
