#datapacks

[Disclaimer: I’m not an expert, I might get things wrong. I have successfully made all these things that I’m describing here, though, so I hope I know enough.]

@chu-likes-minecraft made a handy no spiders datapack which can easily be edited to apply to other mobs. The datapack is on Planet Minecraft (I would link to it but sometimes posts with links don’t show up in tags. It’s very easy to find, though, just search for “no spiders” and you should find a datapack from a user called Chu03.)

You can just download the datapack, unpack it, then go down the folders like so: data > ns > functions and open the file named “tick“.

It should look like this:

Look up the ID of the mob(s) that you want to get rid of. You can find this info on the Minecraft wiki. Usually it’s pretty obvious but it doesn’t hurt to check.

If it’s just a single specific type of mob that has no other variants, you can delete all the code in the file and replace it with this:

execute as @a at @s if entity @e[type=MOB_ID_HERE,distance=0..50] run tp @e[type=MOB_ID_HERE] 0 -65 0

Replace “MOB_ID_HERE” with the ID of the mob you want to remove! Bolding is just for emphasis obviously. Note that I changed “tag“ to “type“.

(The reason why this is so much simpler is because you don’t need a tag when you’re only targetting one type of mob, you can just target it directly. But if you want to target multiple mobs, using a tag is more efficient)

If there are multiple variants of the mob you don’t like or if you want to target multiple kinds of mobs, you can use Chu’s original spider code as is and just replace the spider and cave spider with your mobs, and come up with a new collective tag for those mobs. Let’s say you wanna get rid of endermites and silverfish because you don’t like creepy crawlies; this should work:

tag @e[type=endermite] add creepy_crawlies tag @e[type=silverfish] add creepy_crawlies execute as @a at @s if entity @e[tag=creepy_crawlies,distance=0..50] run tp @e[tag=creepy_crawlies] 0 -65 0

Wanna also get rid of bees? Just add bees to the “creepy_crawlies” tag like this:

tag @e[type=endermite] add creepy_crawlies tag @e[type=silverfish] add creepy_crawlies tag @e[type=bee] add creepy_crawlies execute as @a at @s if entity @e[tag=creepy_crawlies,distance=0..50] run tp @e[tag=creepy_crawlies] 0 -65 0

I’m pretty sure you can use any wording that isn’t an already existing tag in Minecraft? (Although sometimes you might actually want to just use the existing tag instead, just make sure you know what it includes.)

Once you’re ready, just save the file. You don’t have to worry about any of the other files in the pack, just leave them the way they are. Go back up the folders until you get to the level that has the “data“ folder and the “pack“ file and then just repack the pack into a .zip and give it a new name. Make sure you’re packing the “data“ folder and the “pack“ file, not a folder above them. If you unpacked the original datapack into a folder, don’t include that folder in your pack.

Image to clarify:

(You don’t have to use 7-Zip, any equivalent program is fine. #NotSponsored)

Your datapack is now ready. I recommend testing it in a test world first to make sure it works. You can just give yourself the spawn egg in creative and try spawning the mobs and if the pack is working they should immediately disappear as you spawn them in.

If they don’t, try the command /reload. If it still doesn’t work, save and quit to title, then open the world again. If it still doesn’t work, check the pack itself to see if you did everything correctly. Compare to the original no spiders pack to see if you accidentally did something differently.

BONUS: you can also edit the “pack“ file to include your own name in the credits along with Chu’s, but this is not necessary.

Other packs that have already been made and can be found on Planet Minecraft: no zombies, no drowned, no skeletons, no wither skeletons.

Also yes, I did actually make the no endermites/silverfish one because I had to double check that the code I pasted here actually worked so I uploaded that on Planet Minecraft too.

Some extra tips:

If you remove spiders, I recommend adding a custom crafting datapack that allows you to turn wool into string. You can download one from Vanilla Tweaks for example. vanillatweaks (dot) net -> crafting tweaks.

There are also websites that allow you to make your own custom crafting datapacks. One that I’ve used and that is up to date as of version 1.18 is thedestruc7i0n (dot) ca (choose the “crafting” button)

With custom crafting packs you can add your own preferred way to get the resources that you’re missing out on. (This is also handy for people who just don’t want to murder a specific kind of mob, like if you really love cows and don’t wanna kill them you can make a custom recipe for leather. Although in that specific case, Vanilla Tweaks already has a datapack for smelting rotten flesh into leather which I recommend.)

Vanilla Tweaks also has a custom villager pack under “datapacks“ which allows you to spawn in a custom villager to trade with, who you can have selling the items you need.
