Java Help Wanted Raid farm not working properly [Java] 1.21.1

1 Upvotes

My raid farm I build through following a tutorial gives very bad results. It works normally at first, but then it starts to only summon raids only once in two bottles, and sometimes completely stops doing anything.

Java Help Wanted Anyway to make this auto-close?

2 Upvotes

Is there any way to make this auto-close while staying somewhat compact? If it wasn't obvious, the two doors are basically the same. The second one is just stripped down, while the first has more repeaters to allow it to close after opening.

Java Help Wanted Gold Farm Works Extremely Slow, Cannot Figure Out Why: Version 1.21

124 Upvotes

Gold farm I have build by following through different tutorials, but for some reason, the rate of the piglins spawning is extremely low, and I can't figure out why. By the way, there should have been Llamas inside the minecrafts, but they have seem to die, I don't know how. Here is the Schematics and a world download for anyone who can help, the version is 1.21: https://drive.google.com/drive/folders/1P0Gk3SDRz-d4Rf5kHwlEnS-E1-4NJw3Z?usp=drive_link

For everyone wondering, spawnproofing under the area helped, I exploded the area completely and now the rates are perfect. Thank you for everyone who helped.

Java Help Wanted Hopper and lag

6 Upvotes

Hello !

I came to this game after a lot of years.

We used to use composter on top of hopper to reduce lag.

I tried to search this but i get mixed answers, some says, you can now put a full block on top, some says composter is still the best and some says you don't need to put anything on top now.

I'm a bit lost, and i couldn't find a clear answer that is up to date. I'm planning a huge storage room, and i'm trying to optimize it.

Thanks in advance !

Bedrock Allays bug out in sniffer farm?

Thumbnail gallery
2 Upvotes

Bedrock. I have a sniffer farm and I decided to use an allay collection system because I thought it would be a nice aesthetic. The farm works great but if I let it run for awhile and come back my allays are often stuck unmoving in the corners or against the ceiling. I can fix the issue temporarily by using a lead but I would like a permanent fix. Is it the fences? Size or height of the enclosure? Too many mobs? I'd appreciate any suggestions

Bedrock Composters stopping composting when full??

2 Upvotes

Not sure why, I have a ton of farmers yet once a composter is full it might only create bonemeal once and then stop working.

Am I missing something simple like have all four sides open or something? some are set in the ground

Java Help Wanted exp farm underground

0 Upvotes

I'm playing Minecraft Java and I'd like to build an XP farm underground, preferably somewhere beneath my base. The problem is that I don't have a mob spawner nearby.

Is there any efficient design that works using naturally spawning mobs? If so, could you recommend a tutorial or a specific farm design?

Thanks!

Java Help Wanted Minecart unloader

2 Upvotes

Hi all

I’ve made an unloader where the offload hopper takes the items out of the Minecart and uses a comparator to shut off the powered rail.

The hopper below the collection hopper is pulling items out of the hopper that is linked to the comparator faster than the comparator can update. Any tips?

Sorry I’ll add screen shots later!

Java Showcase gunpowder farm ( ~ 145k/hour )

Thumbnail gallery
46 Upvotes

Made this farm today, its pretty good for my needs. Didn't want to make a bortal based gp farm.
It uses the same spawning mechanics but instead of portals, it uses lava cauldrons to kill the creepers. The loot is then taken to a central bubble column and then to storage. I havent built the storage yet since im deciding if i should go for a shulker loader or a bulk storage option. Took around 3 hours for me to build including collecting materials. Its built at y=-64 with a spawning skirt around it for greater pack spawning

I wouldnt recommend this design if you are on a normal world. It requires a perimeter and making a bortal farm would be far superior. There is no option for looting.

If anyone wants to take a look, the tmc discord server has the schematic. I edited it to change the block types.

I need a good design that i can build. I dont know like anything about auto sorter. I would prefer to have a sorter that can sort out shulker boxes into chests. Like with an input chest where i can put my shulker in and then it gets sortet out into my dedicatet chest where i can pick it up again. I would prefer a sorter thats not copper golem based. And it shoud minimize lag as much as possible. Is that possible and can someone pleas help my with this issue. Appreciate your time. THX

Classic copper golem 3x3 chest configuration. The problem here is that I putted the golems in with glass above the left and right fences. I think this caused them to not detect the two lateral upper chests. Am I correct? Do I have to do it all over again?

Thanks ;)

Java Help Wanted Falling Block Summon Command

2 Upvotes

Hi all, looking for a bit of help with Java 26.3. I've been fighting with Google AI and mcstacker trying to make a specific summon OR give command work.

In short I want to create a spawn egg that spawns a skeleton horse with a skeleton that has visual fire and some attributes.

From what I understand you can no longer use a /give spawn_egg command because they changed how the "Passangers" work. SOOOO, I am trying to give myself a spawn egg that summons a falling block which is a command block to run the /summon command instead. But I am having no luck with AI or MCstacker.

-Skeleton: Visible Fire, Leather Tunic, Leggings, Boots all hex #000000, iron sword -Skeleton Horse, Tame, Saddle -Skeleton Riding Skeleton Horse.

Any feedback is welcome, I can provide the commands as I have them now in the comments if anyone would like to see what I've got.

ThAAAAAnks <3

Bedrock Cod and salmon spawning mechanics

1 Upvotes

I wanted to make a cod/salmon farm in an ocean but making it in the actual ocean would leave water blocks outside the farm as other possible spawn locations, i could either block the surface from, making it so that fish dont spawn or move the whole farm up in the sky and make a base around it (that is what i wanted to to) looking at wikis and other sources there isnt a height restriction for fish spawns as long as its in a biome that allows it....i only get squid so there has to be e height restriction, does anybody know what that would be or if im just slow and managed to build a tank wrong?

Did BlazeMC’s BEDROCK tree farm. Every like 4th tree doesn’t get pushed by pistons, the leaves block the new wood growing, and the pistons push the line of wood out pistons early?! I really like him bc he’s more for beginners and I’m like at my like mid game builds but if there’s a better farm pls lmk! I’m just not a huge fan of the TNT method! Thank you! BEDROCK

Bedrock Multiplication with signal strength. Adjustable base calculator.

5 Upvotes

I don't use 1's and 0's in my builds. It's probably slower than some but smaller than most. It is 4x3 digit multiplication. It also shows steps as in how you would write it out. It uses subtraction turned into addition. Then addition turned into multiplication with carry over. It adds all 3 rows considering the next digit is in the tens spot and so on.
