How to get all methods on an entity

[safe pond]

I got probejs already installed, sadly entity.spawned event.entity is any,
I am trying to get all methods on the ender dragon because i want to check his state and do certain things depending on if hes in meele mode etc

Once your ticket has been resolved, please close it with </ticket close:1054771505520717835> command!

[past verge]

you need to run /probejs dump after the event fires for probejs to know the event exists and capture it's types

or you can use jsdocs to manually specify the type of something

/**
 * @type {Internal.EnderDragon}
*/
const entity = event.entity

[safe pond]

interesting, ill try that, but what i also dont understand is that global.d.ts and my editor are not in sync wreidly

check this out

the 5 listed methods are from the text around it

[past verge]

huh

[safe pond]

when i type any method there listed ill get any

so getEntity returns any

[safe pond]

the globa.d.ts file has 78 erroes if that matters

or am i just a dumb dumb rn?

i tried using a ts file and it showed me no sub methods

[past verge]

probes inner workings are magic to me

[safe pond]

also

[past verge]

when ive used it the global.d.ts file has had errors but its worked fine, so not sure if that should be worried about

[past verge]

@winged gorge any ideas on this?

[past verge]

it may be expecting stuff only added in 1.19.2, im not sure how much pruno backports

[safe pond]

I can also dumb it again if that helps

[winged gorge]

global.d.ts file has error is not normal

can you show what errors are they

[safe pond]

wait

why is get and set undefined

[winged gorge]

wtf

[safe pond]

is tsconfig wrongly configured?

[winged gorge]

Nope, it's some mixin or weird thing doing their magic again

I never expect calling getName on params can have such weird names

1.19.2? I'll fix it some time later

[safe pond]

1.18.2 *

[winged gorge]

rip

[safe pond]

not supported anymore?

[winged gorge]

Not really, I'm super busy recently

Try to manually replace <set-?> to param0 and see if it works

[safe pond]

oof, I guess aslong as i have the internal methods i can somewhat do things

one sec

[winged gorge]

Or any similar things

[safe pond]

what if i just remove set?

[past verge]

you would have to replace it with something

[winged gorge]

Use this

The problem is that the methods are having illegal param names

So usually it should be arg0 arg1 or whatever

[safe pond]

?

[winged gorge]

yes

But now it's <set-?> which breaks TS syntax

[safe pond]

resolved all errors

wtf

fixed everything

it works

[winged gorge]

Should be a workaround for now

[winged gorge]

Are you using quilt?

[past verge]

forge

[winged gorge]

smh

[past verge]

based on post tags

[safe pond]

oh i forgot what quilt is

xd

i googled it lmao

ye forge

[winged gorge]

Must be some weird obfuscation/remap problem then

[safe pond]

this is so cool O:

[winged gorge]

Because in forge you have arg0 for those minecraft methods, and in fabric it's $$0, they all work for TS

[past verge]

looks like it might be kotlin

[winged gorge]

[past verge]

https://github.com/raphw/byte-buddy/issues/843

[safe pond]

i got kotlin in here

[winged gorge]

Will fix it some time later

[safe pond]

@winged gorge are you the creator of probe.js?

[winged gorge]

yes

[safe pond]

Thank you for your hard work sir

@past verge also thank you for helping me

[winged gorge]

[safe pond]

ill go back now to buff the ender dragon

and let him shoot arrows or something depending on state

xd

Wait i just get the nearest player and let him aim on him so that he has to run xd

[past verge]

you dont have to run the fastest, just faster than the slowest

[safe pond]

(i resolve it in 2m)

[safe pond]

:D

[thin gull]

[safe pond]

actually i keep it open if i get questions in the next 10m

xd

[safe pond]

do you actually know if i can get the current state of the ender dragon / trigger events on state change / when he gets damage?

im new to kotlin and i dont wanna run it tick based if possible

or worst case connect ticks to the ender dragon

[past verge]

uuhhh

[safe pond]

kubejs*

[past verge]

why are you writing scripts in kotlin

[safe pond]

not kotlin

im brain afk

[past verge]

oh phew

[safe pond]

xd

sorry just casual brain error

[past verge]

i dont think there are many events related to the ender dragon

[safe pond]

so i would need to compare always pos 1 to pos 2 to see if hes moving or not, since hes only not moving when hes on meele mode

[past verge]

or just check the delta positions

[safe pond]

OH yeah

makes sense

how do i add an event listener to an internal tick of ender dragon?

and is tha tthe right location?

(couldnt find any event locations)

[past verge]

kind of

there is no entity tick event

due to the lag potentional

[safe pond]

(what im trying to avoid)

ahh events are on

[past verge]

those arent events

they are methods you can call on it

[safe pond]

i just noticed it

damn

[past verge]

without a tool like mixin you cant modify the code that is called when that method is ran

there is a player tick event, a level tick event and a server tick event.
for any of those you could look for an ender dragon and do stuff on it, but that is costly as you would have to loop through all entities to find the dragons
or you could store the dragon in a list/variable dclared outside the event, so you dont have to keep searching for it. just need to make sure its not dead.

or, the probably best option, is detecting when an ender dragon spawns and then storing that, and having a callback run every x ticks, checking if its dead

[safe pond]

but what if the server restarts or the dragon unloads

when its getting loaded does that count as spawn?

with specific parameters?

[past verge]

on forge, yes

[safe pond]

OH okay

good to know

[past verge]

im not sure about other loaders

[safe pond]

okay, its mostly for a friend modpack

where i wanna spice things up so its fine

but im wondering how i can trigger an event when he for example gets damage

[past verge]

entity.hurt

[safe pond]

but isnt that for all entitites?

[past verge]

check the entities type

[safe pond]

then id have to add an ender dragon check which would be wastefull

[past verge]

if (event.entity.type != 'minecraft:ender_dragon') return

[past verge]

there is no way around that

[safe pond]

am i overestimating the cost of things like that

oh sadge

[past verge]

yes

[safe pond]

im really performance driven dev, so this is kind of hard for me rn

xd

[past verge]

yuo could probably loop over all entities evey tick and not notice it, but if you suddenly get a farm overflow with items, or a lot of players loading lots of entities, it could get noticeable

[safe pond]

Really?

[past verge]

yeah

[safe pond]

i did not expect that

[past verge]

datapacks do it all the time

[safe pond]

not that i will do it

WHAT

wait

thats terrible?

wtf

[past verge]

any @e or @a, even if it has a filter, requires looping over all entities

[safe pond]

?

[past verge]

well @a is players

[safe pond]

no i get it but like why

[past verge]

in command entity selectors

[safe pond]

does mc not keep an array with all players

why then do that?

[past verge]

it does keep a list of players seperarely, and im pretty sure @a uses that, but thats the only entity type they do that for

[safe pond]

bruh

[past verge]

hmm

mc does keep a few lists related to bosses, but i dont think theres one of the actual bosses

[safe pond]

when entities despawn, do they count as died?

[past verge]

but you may be able to get the entity from something like the boss bar list

[safe pond]

oh, interesting

[past verge]

tho thats not public

[safe pond]

my goal was to conditionally register the event

[past verge]

yes

[past verge]

for that you need 1.19

[safe pond]

damnnit

[past verge]

EntityEvents.spawned('ender_dragon', event => {

[safe pond]

in my case im stuck here

wait

[safe pond]

this makes no sense

i just noticed

What is this?

[past verge]

fired for some entities before they spawn

for conditions like light level checks

[safe pond]

Ohh

Is level.tick same as dimension.tick? (since the enderdragon is end only i could reduce the impact that way or?)

(should be fine since i controll the modpack)

[past verge]

level == dimension

[safe pond]

okay thank you

[past verge]

well, actualy
level == dimension && side
cause tehre is a server level and a client level per dimension

[safe pond]

oh

wait

whats the differnce?

wait i should just do global tick, otherwise with level.tick i would need to check the dimension and it would have additional overhead

[past verge]

one is on the server, one is on the client. (if you are playing singleplayer there is a mini server running in the background)
because the server is the authorative one, that is where you can do things like change blocks, spawn entities ect
the client is the pretty one, and its where you do things like spawn particles or sounds.

[safe pond]

Ohh

wait this is troublesome

since if i for example wanna spawn particles before the dragon lets say makes his arrow laser, i would need to somehow check that each tick in the FE or rather the varaible

i would have an enderDragonDoes something initital check then a more specific ones for the detailed particle

[past verge]

you can send particles to the client for them to display from the server

[safe pond]

OH

okay thanks godness

[past verge]

just like how the client has to keep asking the server to change blocks

[safe pond]

OHH

yeah makes sense

this is so much fun

xd

[past verge]

the client level does keep a record of what blocks are where, and technically you can change those, but they will get reset when the server sends those blocks again (ie you mine them)

[safe pond]

yeah that makes sense

[safe pond]

can i also save / load data / save them directly on entities?

[past verge]

yep

event.entity.persistentData.someValue = "hello world"
console.log(event.entity.persistentData.someValue)

note that uses nbt as a storage medium, which can be... finnicky

booleans are converted to 0 or 1 and deleting properties is hard

[safe pond]

one more question (sorry that i use you like an oncall support)
How do i access global variables like all players / all players in a specific level (wanna get closest player)

[safe pond]

oof

okay i just write a string as json

xd

if i need to

[past verge]

event.level.players

[safe pond]

oh

Ohh

im going though event rn

i expected to have far less data

i see so via event i can acess global things and narrow down via the objects to what i need

i see

[past verge]

global in kubejs tends to refer to stuff that is across all script types

instead on global across the server

[safe pond]

to make interval checks like getting all palyers in a dim with a server tick i can just have a counter go up to 20 and run code depending on that right? or is there a better way

[past verge]

if (event.server.tickCount % 20 != 0) return

[safe pond]

or like that

is a planer seen as a mob? (but wreid that byMob and byPlayer are different for set but not for get, i assume its bec of archivements / stratistics?)

[past verge]

technically no

[safe pond]

oh

so how do we get last hurt by player?

last hurt and compare to by mob?

[past verge]

lastHurtByMob

the player isnt a mob, but that method doesnt return mobs

it returns living entities

blame mojanks weird naming schemes

[safe pond]

ahh okay i get it

naming things is hard, i know it as a dev (im a dev but i was so focused with other things i forgot how to code properly 💀)

oh players in creative mode dont display

so how do i test this without constantly dying 💀

brb

[past verge]

/cofh invuln

assuming you have cofh core installed

or ```js
onEvent('entity.hurt', event => {
if (event.entity.player)
event.cancel()
})

[safe pond]

sadly i dont have cofh

[past verge]

the script will still work without it

[safe pond]

https://wiki.latvian.dev/books/kubejs-legacy/page/list-of-all-events but this list doesnt have it?

[past verge]

entity.attack got renamed to entity.hurt in 1.18

[safe pond]

wait entity.attack is us attacking and not entity attacking

oh

[past verge]

its entity being attacked

[safe pond]

ah yeha

i forgor

im an entity

xd

Say, the end was dimension id 1 right?

[past verge]

kinda

[safe pond]

mods can change it?

[past verge]

numeric ids mostly arent used these days

[safe pond]

but the get method needed a number if im not wrong

i tried the_end and minecrat:the end or something similar and it failed

[past verge]

allLevels returns an Iterable

so you need to iterate over it

if you want to get the end just use event.server.getDimension('the_end')

[safe pond]

there is no getDimension

[past verge]

huh

ah

getLevel

[safe pond]

Are there inbuild functions for trig calculations or do i need to do them on my own?

for example distance between entity and mob

[past verge]

entity1.distanceTo(entity2)

[safe pond]

thank you!

monsters have distanceTo, players have it named differently lol

i just do it reversed

[past verge]

players should have it too

[past verge]

that is very weird

cause its on Entity, and all entities inherit from that

[safe pond]

yeah

wait lemme remove the abc one

[past verge]

and there doesnt seem to be anything in kubejs renaming it

[past verge]

AHH

EntityJS doesnt exist anymore

wait im on 1.19

[safe pond]

whats that menu?

and how can i get that

xd

[past verge]

intellij's search in a kubejs dev enviroment

[safe pond]

ohh

Good news, it actually gets players in creative mode, so i can continue testing without dying lol

Is it possible to create projectiles which wont collide with some entities, for example arrows which go though the dragon or that the dragon does not get dmg from that arrow bomb

or explosions if i add some

[past verge]

maybe

if you can differentiate between that and a regular arrow/explosion in the hurt event you can

[safe pond]

so i can basically cancel that an entity is being hurt, cancelling that, would it cancel also the removal of that item?

so i spawn it with special data info, and use that for my checks on arrow entity collisions

[past verge]

it shouldnt do

[safe pond]

/ hurt

[past verge]

yeah

[safe pond]

if it does not cancel the arrow removal i would need to respawn it with same direction which would be bad for performance

i guess i will see once im there

[past verge]

making it pahse through the dragon will be more trouble than its worth

[safe pond]

i see, i just increase the spawn arc and let it not dmg the dragon

[past verge]

yeah

[safe pond]

is this too far with kubejs (i assume ppl would say at this point use java)

Also

returns nan

investigating

[past verge]

never
someone remade a good portion of thaumcraft in kubejs

[safe pond]

Really

wait so why do people say that?

is undefined O.O

[past verge]

because at that point you should really be using java

[past verge]

but its sometimes easier/faster in js, and also its a nice challenge

[safe pond]

(or youre too lazy to learn java)

xd

[past verge]

a fair portion of my knowledge of java comes from reading kubejs source

[safe pond]

makes sense, since they had to figure it all out and create an effective mapping / understand whats usefull and important

you can scheduel events, this is cool

[past verge]

it might be called something different in 1.18

check for things to do with ticks on event.server

[safe pond]

i searched for tick related keywords on server and event nothing

just

[past verge]

time?

[safe pond]

nop

[safe pond]

just scheduel in Ticks

[past verge]

huh

[safe pond]

its also not on the event

[past verge]

youll need to use a counter then

[safe pond]

Yey

but thats wreid isnt it?

what if you wanna calculate durations?

i dont need to really

but out of curiousity

[past verge]

you can use javascripts Date object to get real time

[safe pond]

Oh

[past verge]

or there must be some method soemwhere for in game time

[safe pond]

yeah

[past verge]

it definitely exists on 1.18.2

maybe kubejs renames it?

[safe pond]

the ied told that it was distanceTo

[past verge]

oh wait

aaahhhh

[safe pond]

wait bec i passed on an entity

instead of pos?

[past verge]

1.18.2 still has the wrappers

[safe pond]

wrappers?

[past verge]

EntityJS, LevelJS, ServerJS

which arent the actual thing

they just hold the actual thing and have (some) methods for interacting with the actual thing

entity1.minecraftEntity.distanceTo(entity2.minecraftEntity)

[safe pond]

OHH

[past verge]

i completely forgot

[safe pond]

how can i modify this so this reflects

this also explains previous player method error

this doesnt work

[past verge]

capital s

also the [] says its an array

[safe pond]

yeah i know

i wanna later spawn multiple

for now i code it semi for one

xd

@past verge i made capital S, but it says that enderDragons[0] is any

okay i know what i need to do

[past verge]

does EntityJS even accept generics?

[safe pond]

yeah

thats what i wanted to say, it prob does not

and i need to extract it out and then type it

oh wait

the array was at the wrong loc

moment

nop no generic

i gotta do it like that

@past verge I need to go for now, thank you again for all of your help, Ill hit you up when my dragon is causing complains bec hes killing everyone
