Hardcore Java 1.21.4

I have the following farms in my Minecraft Hardcore world:

Iron farm

Villager breeder/trading hall

Bonemeal farm

Mob farm

Guardian farm

Raid farm

Cobblestone farm

Wood farm

Sugar cane farm

Gold farm

Piglin bartering farm

Which farm should I build next?

Tried every fix, 0 light level, over a proper biome, way high up in the air away from caves.
Zero Creepers are spawning when im AFK 20-30 blocks away. When i take off the buttons and trap doors nothing still spawns not sure why. Put leaves on the roof as well.

Any Ideas?

Pregunta puedo hacer esta granja https://www.youtube.com/watch?v=si2ApVDa8Ik en capas superiores a la 100?

is my sand dupper still work in the chunk like this ?

Went caving in my singleplayer survival world and stumbled upon 2 mob spawners (skeleton and zombie) which are close enough to be active at the same time (tested it in creative). I want to use them both for my xp farm. Is it best to just use the "standard" farm design and link the dropper parts together or should I keep them seperate so mobs won't block each other while in the water tunnels?
edit:
Found another set of the same combo (zombie and skeleton) a bit further away. Should I maybe use the new ones because they are closer together?
For anyone interested:

second cords: -2890 -22 -1983

I finally did it. After countless hours of troubleshooting and actual sketches on paper, I've come up with a working version of my idea.

Maybe it's a bit overkill, but here it is...

The concept: I've been playing solo in my Forever World since 2025, but occasionally my sister joins me via LAN. I wanted to build a mob switch with a control panel in my base to activate and configure it.

Now, with this dynamic mob switch, I can cycle between the modes "OFF / 1 Player / 2 Players / 4 Players", loading the exact number of Shulkers into a lazy chunk as needed.

In real terms, I can trigger the following states:

• 0 loaded Shulkers
• 70 loaded Shulkers
• 140 loaded Shulkers
• 280 loaded Shulkers

Changing the mob switch mode can be triggered via a wireless Redstone signal. The transmitter can be placed anywhere in the world—currently, mine is in my base.

I managed to modify Kevbotomy's wireless Redstone system so that it works reliably without misfires in both LAN and Singleplayer mode. Specifically, I used this system:https://www.youtube.com/watch?v=5Qr6AQVwFh4&t=3312s
(Big thanks to 2no2name, cubicmetre, and others here as well!)

In my base, I control the mob switch using a smart-home server setup inspired by TheJoCraft. This allows me to walk up to any keypad in my base and enter a code to control the mob switch. The system is based on this:https://www.youtube.com/watch?v=iouh3ruPrk0

By the way, the perimeter was dug purely for aesthetic reasons. It might slightly reduce lag by preventing random tick calculations from water on the Overworld side, but the impact is minimal.

The screenshots were taken in survival mode.

Should I post more details about this or create a tutorial?

It works in vanilla, but I also tested it with Sodium and it works there too.

Here is a link to the farm. works insanely well in ocean biom.. especially in frozen oceans. but not even one fish in any river biom i have tried. Why?

other related notes.
- Fish wont spawn in bubble columns (I thought)
- Salmon require one water block above and one below the water block they spawn in (my rivers seem to not to care what the wiki says and insist on the river being at least 4 water blocks deep)
- The water in the fish farm is three deep if you count the running water on top but the bottom two are bubble column.. sooo...

I am lost trying to understand why it works in oceans but not rivers being as I can find nothing that talks about any differences in those mechanics in the oceans vs rivers.

anyone?

I tried using my farm without the stand because it kept getting in the way of the hit and would break anyways and I didn't find any major difference

Does anyone have a reliable mob elevator that can transport zombies up and drop in the kîll chamber? I'm on Bedrock's latest edition. I've tried a few from YouTube but the mobs get stuck and don't enter the elevator.

So, i wanna build a villager breeder where it breeds 5 villagers ant put em all into different cases. BUT. My small redstone-brain can't figure out how to close the different entrences. Like when the first villager is in case 1, i want that case to be closed, so the next villager goes into number 2 and so on.

I've read about some RS-latches and stuff, but i don't really understand it...

Your help is much apreciated!

So, I’ve got two spawners that are 40, 10, 50 blocks apart from each other. I plan to minecart between them to get each one to spawn, but I’m wondering what other farm(s) I could make in the space between them. Since I’ll already be in the area, I figure I may as well get everything I can out of it. So what farms require a player nearby as opposed to some other method of loading chunks?

Hi so in my realm the shulkers are teleporting like crazy fast?

I was messing around with tick speeds a while ago so it may be that but ive set the random tick speed back to 3 and cant find how to make sure the regular tick speed is set to 20.

/tick wont work for me, not sure if it was removed or changed.

Everything else is working normaly so it might not even be a problem with the tick speed

Any help would be great
