The best way is to search YouTube for "bedrock mob farm". Make sure it is a relatively recent video since mob spawning changed within the last year. Also make sure that bedrock is in the title or video description. Look in the comments and make sure there is a comment within the last couple months that says "still works in 1.21"

SilentWhisperer on YouTube has the best mob farms. If you can get a few tridents then his creeper farm is the best. Repairs tools from completely broken to full health in about 2 minutes. That’s about as good as it gets on bedrock without building a guardian farm. By the way, his guardian farm is ridiculous too, but very hard to build.

there's a simple mod FoxyNoTail's Markers Pack, it shows you mob spawn spheres around the marker, which is helpful for aligning the size of mob farms optimally in regards to their spawn distance from a player

Whatever you do, don't make it over a river.

Google scaffold based mob farm! Or the new creeper farm just leave out the buttons and trapdoors on the ceiling and everything will spawn!

You are correct, they’re called mob farms

There's two simple methods.

1. find a spawner and dig it out a bit deeper, then use water to push the mobs into a killing chamber where you can kill then with your sword. A killing chamber is just a little hole where you can hit the mobs but they can't hit you. This video will show you how https://youtu.be/_1y8kQ7Jvbk

2. Can't really explain that well but it's really simple. It's like a long tube in the sky that mobs fall down and die from fall damage in. Look at this video https://youtu.be/1Bn4OvmdFG4

just build four 8x8 platforms in a square with a 2-wide channel between each platform. put water in the channels that funnel towards the center. put a roof and walls over it. bam. mobs spawn on the platforms, they wander around, they fall in the water, water takes them to the center, they fall in a hole. if the fall is long enough, they die and drop their items. if the fall is not long enough they fall and just stand around. if the fall is just the right length, they will get injured to the point where you can just slap them dead.

https://youtu.be/HDTSq89uGOQ this should help!

Use google it’s your best friend

The easiest way is to just find a spawner.

If you have a mob spawner, then dig a 3X3 hole underneath and water all around to push mobs into the hole. Then at the bottom of the hole, make an area to collect mobs so that you can kill them. I hope this makes sense!

try the ilmango one, it should work

You can use Redstone to make a mob farm but your don't have too, just make a large dark room with some water streams that mobs will walk in after they spawn and then have it lead to a pit, and if you want to store it use hoppers connected to chests

Smoke a bowl and click buttons you'll figure it out eventually

For the dark box towers: The spot where you afk/wait is very important. Mobs won’t spawn if you’re closer than I think 24 blocks or farther than 128 (my numbers may be slightly off). If it’s set up where you’re standing farther than 128 from the ground, that keeps ground and cave mobs from spawning, increasing rates in the farm.

For spawner farms: You have to be within 16 blocks of the spawner for it to spawn mobs. You can set up a water stream to carry mobs out of the spawner room, but make sure the end point where you kill them is still within 16 blocks so mobs keep spawning.

You have to make sure there is absolutly no light, and you have to be quite far of the spawner for it to work, another thing you can try is reducing your chunk render for as low as posible, this decreses spawns of mobs in other places besides your farm

I'm working on an automated villager breading system first I need more blocks before doing Creeper Farm or any other farm btw you can use cats instead of water and I need to add carpet spacing to avoid spiders from spawning

Weel nothing honestly I'm in the beginning of the game and testing some farms just trying to make a mob farm for the first time i used to make those square farms with no Redstone but this is different at least for me

This farm is great in will probably produce more than enough items for your needs.

But a tip for the future: This general mobfarm design is fantastic, but you kinda built it the wrong way round with farm vs afk spot.

The better way to run this farm would be to build it so the hoppers the mobs fall on are just above the ground, maybe even sunk into the ground (tho in that case you'd have to light up the area around it). Then you need to afk on top of the farm exactly 127-128 blocks above them. That way mobs will still only be able to spawn in your farm, but you are also taking advantage of a lower y-value.

In java, the lower down in the world the highest block of that specific x and z coordinate are, the faster the spawns will be. For example if you build a mobfarm 50 blocks over bedrock, it will be roughly twice as fast as the same farm 100 blocks over bedrock.

Essentially, by building your farm all the way at the build limit, you made the farm as slow as it is possible for this specific design to be. If you had built it with the hoppers at y65, it would probably be twice as fast.

I just built one of these in my world, and spent a while AFK - came back to nothing in the chests and confusion.

Did a bit of checking everything, and it turns out I'd built my AFK platform 2 blocks too high, so the campfires were 130 blocks down. I Used freecam and could see all the mobs despawning just before they hit the fire.

Quickly dropped the platform down, and now I have more gunpowder than I think I'll ever need for my single player world.

I admire your work ! 😍

Make a trident killer. It just uses pistons to constantly move the trident, damaging mobs. Look up a tutorial on yt for it

Here, you can replace the bottom grass blocks with hoppers to collect the loot.

So use a Trident?

if you are not gona use the trident killer just place a carpet on the hopper atleast so the xp dont get stuck in there

Wolves probably and/or maybe a trident killer
