i know i could do it in the tags event, but can i do it outside of that?

inside your event u can do this, feel free to move the loadings outside of the event

const Registries = Java.loadClass("net.minecraft.core.registries.BuiltInRegistries")
const TagKey = Java.loadClass("net.minecraft.tags.TagKey")
const myTag = TagKey.create(Registries.ENTITY_TYPE.key(), "minecraft:frog_food")

let level = event.getLevel();
let entity = event.getEntity();
Registries.ENTITY_TYPE.getTag(myTag).flatMap(holders => holders.getRandomElement(level.getRandom())).ifPresent(holder => {
    let type = holder.value()
    let createdEntity = type.create(entity.getLevel())
    createdEntity.setPos(entity.x, entity.y, entity.z)
    entity.getLevel().addFreshEntity(createdEntity)
});

you can take an example here how to get entities by a tag

BuiltInRegistries.ENTITY_TYPE.getTagOrEmpty(tag) also exists. It returns an iterable of holders. The holder.value() returns the entity type then

thanks for helping me out so much recently mate

kinda confused on what im looking at exactly though haha

[frigid delta]

at what part of this code is an array of stuff in that tag being returned?

also, where do i find the minecraft source code?

im assuming from some specific mapping but idk

is it const myTag = TagKey.create(Registries.ENTITY_TYPE.key(), "minecraft:frog_food")?

[viral jetty]

^ this create the TagKey object u need to lookup in the Registry yep

BuiltInRegistries.ENTITY_TYPE.getTagOrEmpty(myTag) returns a iterable you can loop over

for(let holder of BuiltInRegistries.ENTITY_TYPE.getTagOrEmpty(tag)) {
  let entityType = holder.value();
}

[frigid delta]

got it alright, thanks

now uhh.. how do i convert net.minecraft.world.entity.EntityType into its entity id

like instead of entity.aether.slider i want aether:slider

[viral jetty]

eh does holder.key().location() exists

idk

[frigid delta]

time to find out

constants/vars.js#10: TypeError: Cannot find function location in object entity.aether.slider.

:(

[viral jetty]

did you call it on the holder or the entityType?

[frigid delta]

i was doing it in the declaration ```js
for (let holder of Registries.ENTITY_TYPE.getTagOrEmpty(myTag)) {
let entityType = holder.value().location()
}

so yea holder

[viral jetty]

no, you call location() on the entityType

holder.key().location()

[frigid delta]

oh wut

[viral jetty]

damn momo

[frigid delta]

oh wait

whoops

[viral jetty]

alternative you can BuiltInRegistries.ENTITY_TYPE.getKey(entityType)

[frigid delta]

listen im running on 4 hours of sleep

ah yea that worked 💀 sorry

[frigid delta]

like BuiltInRegistries.ENTITY_TYPE.getKey(entityType).location()?

where do i find this class i wanna read some java

[viral jetty]

no, that returns you already a resourcelocation

[viral jetty]

download an MDK, best u can do

[frigid delta]

yea but im lazy

[viral jetty]

BuiltInRegistries.ENTITY_TYPE.getKey(entityType).toString() is probably what u want

[frigid delta]

this was returning minecraft:pig 31 times until i realized i forgot to change to holder.value() instead of holder.key()

lmao

that does it though, thanks

is there a list of other tag types? how would i try to use biome tags or block tags?

assuming i just have to change ENTITY_TYPE

[viral jetty]

yes

use probejs, they should give u all possible registries

[frigid delta]

hm? how?

[viral jetty]

after dump it should be able to autocomplete BuiltInRegistries

[frigid delta]

i guess not?

idk if this is what you meant lol

[viral jetty]

does it need a jsdoc for type

/**
 * @type {Internal.BuiltInRegistries}
 */
const BuiltInRegistries = Java.loadClass("net.minecraft.core.registries.BuiltInRegistries")

not sure if thats the correct type

u have to check somehow

[frigid delta]

im rusty on my jsdoc but i know this should theoretically work right?

if that is the right type even

no clue how i'd check lol

[viral jetty]

yeah it's the wrong type name

you have to search in the typings file from probe

[frigid delta]

🤷‍♂️

[viral jetty]

@glacial nebula

he sleeps probably

but when he is awake, he will tell u

[frigid delta]

Alright hopefully lol

[glacial nebula]

The name changes between versions

You can use the RegistryInfo provided by kubejs

but I don't have pc around me now so you better figure out yourself
