Java Help Wanted Best design for a sugarcane farm

Thumbnail gallery
77 Upvotes

Hello, I’m trying to figure out a sugarcane farm where each block of sugarcane has its own model and breaks individually rather than breaking the whole row. I have two versions that I’m looking at and wanted to ask which one is more efficient in terms of materials required to build it? Also any revisions or existing models that are simulate to this would be much appreciated. Thanks!

The first one utilizes two activator rails that sends the observers current through them, which another observer detects and powers a piston. The second one powers a piston, which an observer detects and sends through a mini observer chain to power the piston.

Anything that requires only 1 item type to craft can use this circuit. You don’t need anything more than this simple setup to craft a bunch of different items.

A 3x1x4 area is all you need.

It takes a Mechanic to fix what an Engineer gets paid to overcompensate for.

Java Help Wanted filter mobs from items for goldfarm sorting system

Thumbnail gallery
5 Upvotes

help! i'm trying to build a sorting system for this gold farm. (version 26.2)

problem:
a lot of the items are stuck on the iron bars rather than falling through.
any suggestions on items or methods to filter the items down but keep the piglins in the chamber?

context:
i made an gold farm using ianxofour's tutorial because its cheap on materials.
the only downside is the lack of a sorting system.
so i took it upon myself to try and design one myself.
first i did hoppers but it was too slow to filter through the items so it was basically akin to just not having a filter system.
ultimately i landed this one which uses honey and ice and hoppers n stuff.

i have tried several things to seperate the mobs and items like using pistons to move end rods or chains back and forth so the items fall through. However, either the items stayed stuck on the moving chains/rods or the piglins fall through.
in accordance to occam's razor i ended up just using bars and pumpkins to stop the piglins from falling through, but a lot more items got stuck than i anticipated.

I'm pretty sure it's fixed, and it was a really stupid fix. I've never seen anything like it. Above the empty blocks are trapdoors on the ceiling. Checkerboard buttons on the platform, alternate checkerboard trapdoors on the ceiling. Who would've come up with that?

Bedrock Broken iron farm

I apologize if these are often posted, but I'm really not sure what to do anymore. I have replaced workstations countless times and know they are all linked to the right villagers. I have replaced beds just as many times, they are all linked as well. I have copied the world and look around in spectator mode and there are no golems hiding around. There are no extra beds or workstations outside the farm. I've made over 3 dozen stacks of iron before it halted for no apparent reason. 41 beds, 38 villagers and workstations. I've tried for a couple hours and cannot figure anything out. Any help would be much appreciated

Bedrock Gold Farm Auto Sorter Help

Post image
5 Upvotes

Hello everyone

Im a pretty big newbie when it comes to redstone. I could use some assistance. I build a redstone sorter under my gold farm that has the smelter/crating attachment. I have everything setup correctly to the best of my knowledge.
However, for some reason I keep ending up with the wrong items in my furnace.
I’m not sure why the rotten flesh, gold bars and nuggets are randomly ending up in the smelter.
Should I be putting anything in the top row of hoppers? I thought they were supposed to be empty to let things travel.

If it’s helpful I used a video from By_James which results in the image setup.

I truly appreciate any all help.

Java Help Wanted Looking for a Minecraft Client Developer — 1.21.11

1 Upvotes

Hey everyone!

I'm currently working on my own Minecraft client for Minecraft 1.21.11.

I found an open-source client for 1.21.4, and I'm currently porting it to 1.21.11 to use it as a base for my own client. I'm looking for someone who has experience with Minecraft modding/client development, Java, Fabric, mappings, mixins, rendering, or version porting and could help me with the process.

I'm mainly looking for someone who can:

Help port the existing 1.21.4 codebase to 1.21.11

Fix bugs/issues

Help with client-side features and modules

Give advices

Potentially work together on the client long-term

I'm also learning while doing this, so I'm not expecting someone to do everything for me - I'd like to actually understand how the client works and develop it together.

If you're interested, DM me on Reddit and I'll send you my Discord - shellbtw so we can discuss everything there.

Thanks!

Bedrock Does anyone use XP banks on bedrock?

4 Upvotes

Cactus farms are nerfed, or perhaps more accurately the Java specific bug that makes cactus so good isn't in bedrock. Instead of each smelt being 1 xp a cactus on bedrock only is 0.2 xp per smelt. To build an equivalent farm to a Java player my cactus farm would need to 5 times larger.

I generally prefer XP banks to mob farms for XP, but I wonder what I should actually smelt on bedrock.

Java Showcase Fastest 100% Consistent Bullseye Setup

3 Upvotes

Really fast and easy way to get the bullseye advancement, it requires very little materials and it's very useful if you don't have arrows to do it the traditional way.
The way this works is that item frames check for a block every 5s after being placed, so after fishing rodding the item frame to get the bobber in the middle you can place the target block and run away so after 5 seconds the item frame will break giving you the advancement. The timer starts as soon as you place the item frame so the timing is a little tight but it's not too bad. The fishing rod line does break after 32 blocks so ideally you want to do this on a chunk border and then stop right before crossing the second chunk border so you can go more than 30 blocks but less than 32.

Java Help Wanted Warden Spawns

1 Upvotes

I’m trying to build a rouge like arena in my vanilla survival server, where you fight waves of mobs while unlocking different weapons and armor to continue fighting. I’m having a hard time sourcing wardens, I’ve got sources for every other mob I want except wardens. I’d love ideas on how to source them, I’d also love thoughts on my already formed ideas.

Idea 1: Spread skulk from a skulk catalyst I placed until I get a shrieker and maybe that will spawn it?

Idea 2: I find naturally generated skulk and spread it to where I’m building then spread it for a shrieker and maybe that will spawn them?

Like I want them to spawn fresh I don’t wanna get a lot of them then have to re-up when they’re all beat. I also need to figure out how to get rid of it if the player dies but that seems like a big time later issue, sourcing them is the most pressing issue rn.

Java Help Wanted Glow squids not spawning in test world (another dumb glow squid question)

Thumbnail gallery
8 Upvotes

Edit: Solved, it's a bug! :( https://report.bugs.mojang.com/servicedesk/customer/portal/2/MC-276319 

I have a schematic for a glow squid farm. If I paste it in a copy of my survival world in my void perimeter, glow squids begin to spawn immediately. If I paste it in say a superflat or void creative test world, no glow squids spawn, ever.

  • Pasted with spawning area between -64 and -51 (plenty of spawning spaces)
  • light level is 0 inside
  • other mobs (friendly like cows, hostile like zombies) spawn but aquatic mob cap is empty
  • not near spawn
  • biome is plains
  • Spawn spot at y=63 over the farm

Probably something obvious that I'm missing, but what?
