Script API General

[haughty kernel]

Hmm... okay... it's a shame there isn't a beforeEvents page for this event.

[warm mason]

mojang can't add support for everything at once + inventoryChange isn't just player moving items, it also about picking items up, modifying inventory through API and all that, so I don't think we will ever have beforeEvent for that

[haughty kernel]

I know that, but it would be great to have more beforeEvents in the player's inventory, like canceling equipping equipment, or preventing the player from selecting a specific slot in the hotbar.

Hello everyone

[zinc breach]

if a player is on the death screen does checking player.isValid return false?

want to use a title command

[snow knoll]

If I'm not mistaken, a dead player is still valid

[zinc breach]

is there another function I can use for that

because I'm pretty sure title commands fail if youre on the death screen

how about health component actually

[snow knoll]

Not entirely sure 🤔
Not very familiar with the component or the command tbh

[zinc breach]

I'll test it out later but it should work

does player.setDynamicProperty() work even if the player is not valid

[zinc breach]

and is there a way to make an entity aggressive to a specific entity only? so say make a zombie aggressive to a spawned chicken or something

[cold grove]

Not valid

Even With instant respawn i have to wait 1 tick

[zinc breach]

            let virusTicks = 0;
            system.runTimeout(() => {
                const virusInterval = system.runInterval(() => {
                    if (victim.isValid || virusTicks > 60) {
                        system.clearRun(virusInterval);
                    }
                    virusTicks++
                },10)
            }, 200)

this should run only when they respawn then right

[cold grove]

Umm no?

You can use playerSpawn event

[zinc breach]

you just said it returns false if theyre on the death screen right?

[cold grove]

Yes

[zinc breach]

this just checks to see if theyre valid every 10 ticks and if they are then that means they respawned

[cold grove]

I recommend to use playerSpawn

[zinc breach]

this is for an ability function tho I'm trying to keep it all in there

[cold grove]

You can listen to events in any moment

function myEvent() {
    world.afterEvents.playerSpawn.unsbscribe(myEvent);

}
world.afterEvents.playerSpawn.subscribe(myEvent);````

[fringe hound]

Yo anyone wanna work on my realm with me? (I'm not dead weight I could do it myself and have actually it's done now and my friends and I play on it currently) But none of them program or make addon so I'm looking to make friends with someone with skills like mine so we can make new exciting content for the realm. We're working with some cool systems such as: a magic way, and dorios RPG core (which allows us to make and register our own trinkets. I'm currently working on some atm) I would prefer if you can build comfortably as well as we're trying to make a nice city on the realm and don't need anymore cave house people lol. Let me know if you're interested and we can talk about details!

^must have PC and mic

Should mention my skills too: I can script comfortably (I've ran into enough problems know I can work things out if need be) and can do any of the other things an addon needs like items, feature rules, loot tables, entity behavior. Im not a very good artist tho full disclaimer lol.

[fallow minnow]

FINALLY

{"owned":[12],"selected":[12]}

is this a good way to do it?

numerical id based

[supple perch]

sure but ngl i think using the number as the index and turning it into objects is better than an array loop for many reasons but that's your choice

[supple perch]

also I'd recommend bit masks

You're gonna need a 5 bit integer tho since you have 20 ranks

[supple perch]

(lightning fast, way better for every possible situation basically)

it's complicated tho so yeah

but I'm sure you can find enough tutorials on youtube or smth like that

[fallow minnow]

well the only reason i have the ID thing is because

{"owned":[12],"selected":[12]}
``` this wont JUST store ranks, itll store other cosmetic items with unique ids and i just do checks script side to see if they already have a certain cosmetic id selected and just replace it

so like

1 - 99, chat ranks
100 - 199 capes / wings etc
200 - 299 hats / misc

or however else i do it

[supple perch]

you can still use bitmasks :)

even better

you should

[fallow minnow]

but question what does it actually like

[supple perch]

but yeah you'll definitely use a massive amount of bits prolly

[fallow minnow]

do

and wouldnt it take up more space?

[supple perch]

it just stores numbers

[supple perch]

nah

it's js a number

literally that's it

gimme a sec

[fallow minnow]

but like

would i make the ids bit masks?

or

[supple perch]

no not really

I'm not too familiar with like performance differences of access in an array and in an object

[fallow minnow]

well tbf i am only updating when they change another one, and its just stored in the memory as cache

so i imagine its super fast stil

[supple perch]

but you can use js const obj = { 0: ///, 1: ///, };

or

const obj = [
  ///
  ///
];```
and use `obj[idx]`

[supple perch]

well probably it's fast currently

but if you ever need persistence

you might want to look into bitmasks

stringifying or just serializing in general isn't good since you store alot of data

[fallow minnow]

i dont stringify

[supple perch]

but it's unavoidable, but for certain things like flags, indexes, etc. you can use bitmasks

[fallow minnow]

yeah i was thinking about flags

[supple perch]

i was just saying

[fallow minnow]

oh

i dont really care about size as well

[supple perch]

not really about the size

[fallow minnow]

its getting sent to a postgreSQL database

[supple perch]

it's about, nvm

well idk if I'd do that tbh

but oh well

[fallow minnow]

do what

[supple perch]

persist ranks and stuff in an external server/db

not that it's bad

it's just kinda inconvenient

[fallow minnow]

nooo

i mean

so

im just storing which ones they own db side

and which one they have equipped

ill need it for later on indexing and counting up how many exist

[supple perch]

yea i wasn't talking about the perf and size this time

i was talking about like the general issues like if the external server were to go down

or bad internet

yes you can guard such systems

but basically it's inconvenient for the players to have to wait for everything to get back

[fallow minnow]

i dont think it will ever go down to be fair

[supple perch]

but that's only at the worst case

[supple perch]

yea probably

[fallow minnow]

and their data is cached upon joining

[supple perch]

I'm just saying

[fallow minnow]

so im not just grabbing from the database each time

[supple perch]

just my opinion, I'm not judging lol

you can do whatever you want to, it's your server dude

[fallow minnow]

its just a locally hosted postgreSQL database through docker, which i read and write to from script api

[fallow minnow]

ikik but i still dont understand the bit part

[supple perch]

which part of it don't you understand?

the actual ops?

or the why?

[fallow minnow]

yeah that and like where would i actually use it?

[supple perch]

well

[fallow minnow]

would i store each rank in a bitmask?

or

[supple perch]

let me explain

firstly do you know binary?

or should i explain it?

[fallow minnow]

i do not 😭

[supple perch]

since bitmasking heavily relies on it

[supple perch]

give me a second

I'll make a quick drawing

and then explain

okay my drawing app is broken

I'll just have to settle for this representation

[8][4][2][1]
[0][0][0][0]

alright so this is the binary representation of 0, pretty simple

the numbers on the top are like, imagine them as a value only there when it's one

[8][4][2][1]
[0][0][1][1]

this is 3

basically bits are each switch

like one bit, is one switch

0 is off

1 is on

we add the numbers on the top of the switchs that are on

[supple perch]

the top part actually uses a formula

2^idx

so for the first bit, it's value is 2^0, which is 1

the second bit it's 2^1 which is 2

and so on

[fallow minnow]

ohhh okok

so

[supple perch]

any questions so far?

[fallow minnow]

i understand it a little bit

[supple perch]

what part do you need help with

[fallow minnow]

so an idea would be to store owned cosmetics as a bitmap

i generated a number

i basically convert the ids to bitmap type thingy

[supple perch]

yea kinda..

[fallow minnow]

1073741823 is ids 1 - 30

[supple perch]

what

[fallow minnow]

like that?

[supple perch]

no

well

actually now that i think about it

telling you to use a bitmask for storing the selected rank ids is dumb

because you can select many IDs that are big in number

[fallow minnow]

isntead of having an array like

[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30]```

i could just simplify it down to 1073741823

[supple perch]

that could probably reach a big number that'd need bigint

[supple perch]

yea basically

it's better if you had a set number of slots like say 3 slots for example, that'd be much more useful in that case

[fallow minnow]

wdym?

[supple perch]

or actually nvm you can use like a Uint8Array or something

[fallow minnow]

like this

function getOwnedRanks(mask, maxRank) {
    const owned= [];

    for (let id = 1; id <= maxRank; id++) {
        const bit = BigInt(id - 1);
        if ((mask & (1n << bit)) !== 0n) {
            owned.push(id);
        }
    }

    return owned;
}

const mask = 1073741823n;
console.log(getOwnedRanks(mask, 99));``` returns the array of which ranks i have from the mask number

[supple perch]

sorry I'm still learning binary myself too, your case requires a bit of thought since it's alot of big numbers like 30 and more

[fallow minnow]

[
   1,  2,  3,  4,  5,  6,  7,  8,  9,
  10, 11, 12, 13, 14, 15, 16, 17, 18,
  19, 20, 21, 22, 23, 24, 25, 26, 27,
  28, 29, 30
]

thats actually kinda cool

[supple perch]

well, it gets even cooler once you truely fully understand it, cuz it feels like you just unlocked a cheat code

[fallow minnow]

it seems very nice for storing data like that

[supple perch]

i recommend asking a professor or like watching a tutorial

or even an LLM explaining

[supple perch]

yea it is

i gtg

good luck on learning!

and on your server

cya

[fallow minnow]

cya! thanks for explaining that to me its pretty cool

[buoyant canopy]

is this the optimal binary search ?

const count_items = (entity, item, guess) => {
    const command = (count) => `testfor @s[hasitem ={location=slot.weapon.mainhand, item=${item}, quantity=${count}}]`
    const check = (count) => entity.runCommand(command(count)).successCount
    if (guess && check(guess)) return guess
    let low = 1, high = 64
    while (low != high) {
        let mid = (low + high) >>> 1
        if (check(`..${mid}`)) high = mid
        else low = mid + 1
    }
    return low
}

[distant tulip]

won't this return true if the player have 0 item? ..count

[slow walrus]

low should be 0, otherwise it'll return 1 when the player has 0, and in the while loop, using low < high is a bit clearer

but otherwise yeah, that's optimal

I would also add > 0 after the successCount in check, cause rn you're returning a number

doesn't make a difference in the if but it's clearer

[remote oyster]

How frequently is count_items being called?

[round bone]

How long is PlayFabId of a player?

[buoyant canopy]

how would the entity have 0 items?

i don't get it?

this is for entities not for players, it will only run when the script determines that the entity has a specific item in its main hand, so i can't be 0

[round bone]

Pigs, cows etc. do not have any items

[buoyant canopy]

At last 😭

[fallow minnow]

😈 😈 😈

[dusky flicker]

make it with an array

since the id is linear

[round bone]

This is probably an array already

[dusky flicker]

so theres no reason to store the id inside the object

[round bone]

He has to remove id field and calculate it with by an index

[dusky flicker]

i just think that it would scale better if he made a registering system

instead of everything being hardcoded

[warm mason]

mojang is his sensei

[fallow minnow]

wdym?

[dusky flicker]

instead of hardcoding like this, itd be better if you made a way where you register these data instead

like

let id = registry.register("Red", "red", "static");
//now you use the id for the operations

[fallow minnow]

ohhh yes

that would be cool

can do that

but question

what difference does it make?

wont it just be in an object either way?

[dusky flicker]

if you want to modify it, you dont need to write a raw object

with modify i mean, changing some data or adding a new one

[fallow minnow]

hmmm true

i already do that for my generator things

[dusky flicker]

im supposing that array would change during runtime

if it doesnt, i dont see a reason for so

[warm mason]

what's this for?

[fallow minnow]

registering generators

[warm mason]

I see

damn, that's very cool ui

[fallow minnow]

tyty

[warm mason]

I hope they will improve DDUI soon, cuz I don't want to struggle with JsonUI...

[wary edge]

Did they change onMineBlock that you need to set back to inventory to update durability?

[dusky flicker]

since everything follows the same pattern, i personally think that passing arguments and then creating the object inside the function would help

if ur not using ts, its pretty easy to write a typo

and get some weird error

i personally used to struggle with this kind of thing

[fallow minnow]

wdym

oh like

instead of typing out the "type" etc.. i just have arguments?

[dusky flicker]

yeah

[dusky flicker]

instead of this
.register("id", "item", 64, 5, "display", 2)

then you simply document the function to tell what each parameter does

so you dont write something like
.register({displayname: "displayname", ...}) somewhere

[fallow minnow]

yeah

[dusky flicker]

for sure, this supossing your not using ts

but i didnt see anything related to ts on the codes you showed

[fallow minnow]

i do use ts

i havent used js in like 4 years 😭

[dusky flicker]

xd, mybad

[fallow minnow]

the errors are very nice

[dusky flicker]

so you can simply ignore this advice

[fallow minnow]

i mean its still nice

[dusky flicker]

and use an interface as argument

[fallow minnow]

yeah

[untold magnet]

can i detect the potion type in 2.5.0 api? and what should i use to do so?

[buoyant canopy]

i came here to say that the fluid container block component has a setPotion method but doesn't have a getPotion method, what a coincidence.

[buoyant canopy]

for items it's item.getComponent('potion')?. potionEffectType.id

[untold magnet]

basically i need to detect the normal potion (water bottle) and nothing else, like if (potionType !== 'something') return

like normal potions wont be detected, but the normal water bottle will be detected

[untold magnet]

got it,

[zinc breach]

can I use this for changing players skins?

function changeSkin(player1, player2) {
    const skin1 = player1.getComponent("minecraft:skin_id").value;
    player2.getComponent("minecraft:skin_id").valua = skin1
}

like would this work

[sudden nest]

what's this level_tick? is it related to scripting ?

[open urchin]

no, players do not use skin_id (unless you've modified the player json definition)
also skin_id is just a number, it's like variant and mark_variant and doesn't come with any actual functionality

[open urchin]

It's not related to scripting, unless your script is doing something that would make the world slow down
Did you do anything to cause that spike?

[sudden nest]

not sure but i think yes, cause i am using my cache instead of getBlock, not sure if this is the culprit behind that spike

[open urchin]

caching Block instances shouldn't do anything like that, it'll just increase script memory usage

[sudden nest]

the scripting has an average of 10-40 though, so i am not sure where that came from.

[sudden nest]

yep, that's what i think it should. not sure bout this level_tick

[wary edge]

It's so stupid onHitBlock doesnt register if its mining.

[zinc breach]

is there no way to change their skins without using player.json? I am trying to see if I can make players morph into other players/entities

[dusky flicker]

try using the profiller

maybe it helps you to find out what caused the spike

[snow knoll]

Well, for entities, it depends on if you're willing to do in terms of stop players from having access to their offhand slot, or any of the armor ones
You can't get a players skin, though, player.json or not

[fallow minnow]

do you know how to get this on bds?

[wary edge]

Client scripting in 2026 isn't happening.

[lyric kestrel]

Worth a shot 😔

Are material instance definitions based on client?

If the definition of the texture is statically defined on the world, why couldn't the scripting method point to the texture definition defined by the world and not the client based texture?

Like gather it through the texture Atlas

[sudden nest]

Nope, haven't tried BDS as the target yet

[fallow minnow]

i tried for a while and it just won’t connect

[warped kelp]

Hello! I come asking if there as an alternate for "on_hit" for weapons and tools that used to use the custom component that could be run via scripts with the function array

[fallow minnow]

i did what u said ts so peak

[warped kelp]

Hello! May I ask where I place the item custom component? Is it in components of the item or separate?

Thisi is so that a script to detect when an item is used or used to hit a thing gets read and runs a function!

[warped kelp]

Nevermind, it works!

[thorn flicker]

now your just somebody that I used to know

[wary edge]

I have faith in 2085.

[round bone]

I'd add enumerations to type and render, but it's very clean approach

I use the same approach across my projects also 🙂

isnt setdynamicproperty must do its work just well without any resavings? like if i call getdynamicproperty second time in tick, it gets it, but when i do it next time it gets empty again

[wary edge]

If you:
item.setDP
item.getDP

in one function call it will work.
But if exit the function and lose access to the item object, doing item.getDP won't return anything since it hasn't been set back to the world.

[stone bridge]

how to save it to the world easily

[wary edge]

Just set it back to the inventory.

[dusky flicker]

a friend of mine which created the miniblocks has the same issue, i forgot how texture of blocks work, but try using a single permutation as a number and map this number to some X,Y axis coord

like, if you got 6, and you know its 5x5, then 6 = (1,1)

[distant tulip]

the performance impact is not worth it, it might be best to use entity

is there any entity that getComponent("equippable") equippable work on other than the player?

[warm mason]

no

try to use player runtime id lol

[buoyant canopy]

not even armor stands?

[snow knoll]

Just get the inventory component

[buoyant canopy]

they do have an inventory component???

i am looking at the entity file of armor stands, they don't

[wary edge]

No its disabled.

[snow knoll]

Nvm, then

[spice finch]

Is there an easy way to make items on the ground unable to be picked up?

[wary edge]

Use the before item pickup event.

[spice finch]

didn't know that was a thing. thx

another thing, is there anyway to spawn an item entity. it isn't one of the options in dimension.spawnEntity()

[wary edge]

spawnItem

[spice finch]

ah, thanks

[broken pawn]

import {ItemStack} from '@minecraft/server'
dimension.spawnItem(new ItemStack('minecraft:egg',1),entity.location)

[warm jungle]

question, does scripting affects the ram? Like how much will the game consumes RAM, if you have alot of arrays and stuffs it's gonna slow down everything?

[fallow minnow]

it really depends on how much you store

even around 50mb -200mb of data is totally safe in my opinion

for my server at least

8gb of ram

but if its just for storing player data youre chilling lowkey

i save their data in cached memory and even if i hit 10kb per player which is around 10,000 characters its perfectly fine for 50 players

[remote oyster]

Using memory is fine, but you want to make sure your memory is manageable and not being neglected in such a way where it steadily grows without notice. This is what we refer to as a memory leak.

[round bone]

Like in every single other program. More variables, more memory

[dusky flicker]

in general not due to the minecraft scale

at least the amount you can control

[warm jungle]

Thankk you for the answers 🙏

[subtle cove]

i'd recommend using other data types too like Map & Set

[dusky flicker]

i dont think quickjs optimizes it too much

if the key is a string, probably its better to use a raw object

[sharp elbow]

In traditional settings, using Map vs object will typically depend on how many keys you expect to have.

IIRC objects lend better to smaller sets of keys. Maps lend better to larger sets of keys

[hoary frigate]

Does anyone have any idea how to remove the limited text in the new update
-# why would they do such thing 🥀

-# context the command gets cut off cause of the text limit

[lyric kestrel]

The performance impact of that is so much worse when using it as a block entity

Unless I was testing it wrongly, which I admit could be the case

[dusky flicker]

how many keys should it have to be considered as a 'large set'?

[sharp elbow]

Really depends. This is where we start running performance metrics

[dusky flicker]

thats why i hate js

all the knowledge you have about optimization can simply be thrown away depending on the runtime

[sharp elbow]

At least it is a known runtime; it's no guarantee, but in theory we can look up existing performance metrics of QuickJS and make some guesstimates on how it'd perform in Minecraft

[dusky flicker]

do you think instead of using a Map for strings, using an ART would be better in js for large amounts of data?

i mean

you got an Art that returns some ID idk, and use it as index inside an array

[fallow minnow]

what are some good ways to detect memory leaks?

[lyric kestrel]

Usually Maps are better as they are hashed with an O(1) time, allocating them to a specific lookup "co-ordinates"

[last latch]

Only thing I could think of is TPS lacking behind but not sure which memory leaks you mean

[lyric kestrel]

You could use Mojang's VSC Debugger

https://marketplace.visualstudio.com/items?itemName=mojang-studios.minecraft-debugger

[fallow minnow]

i tried but no clue how to get it working on bds with a vps hosting it

[lyric kestrel]

Oh.

Fair

Would this not work the same?

[fallow minnow]

not really sure

i use my vps ip, local and others

opened ports

nothing worked

[lyric kestrel]

Did you put the configurations as shown "allow-outbound-script-debugging", "allow-inbound-script-debugging" into the server.properties file and set to true?

[fallow minnow]

yes

[lyric kestrel]

At what kind of world tick in Milliseconds is considered slow/bad?

[subtle cove]

for non-dynamic object, yes {} is ok, but when keys are removed, added, and lotta changes or dynamics, Map does better imo. I've had experience with leaking objects with just {}, so that's where I learned my lesson.

[fallow minnow]

honestly i wanna stay away from anything below 18 tps

[lyric kestrel]

Idk how to check tps 😅

I just know how to check like server in MS

Through the Bedrock debugger

[last latch]

Count how many ticks are ran each second (if it even matters lol)

[dusky flicker]

in js you cant exactly

the garbage collector does so for you

the unique thing i'd say is to dont save too much data that cannot be deallocated due to something pointing to it

[fallow minnow]

im using like

htop and some RSS readers and just logging everything and comparing

[dusky flicker]

i dont remember if the debugger has got something related to memory

but you could try using it

sorry, not debugger

profiller

[fallow minnow]

i cant get it to link 😭

oh yeah

no i cant get it to link

and i mean it seems to be fine

the mem keeps slowly rising but im not too sure if its from a memory leak

i started at like 2.33gb

but then the RSS for the bedrock server isnt really rising

it fluctuates a lot

[lyric kestrel]

Holy

[fallow minnow]

?

is that bad

[dusky flicker]

you should profile the addon itself

[fallow minnow]

thats not just the bds btw

[dusky flicker]

htop sees everything

[fallow minnow]

thats everything

bot, bedrock server, website, sql database

[dusky flicker]

and minecraft by itself might have alot of things cached

that would make it harder for you to figure out if its your addon or not

[fallow minnow]

true

and it just goes up and down up an down

[lyric kestrel]

When you said it just keeps slowing rising, kinda?

Like are you doing anything?

[fallow minnow]

but umm i started at 803

nope just sitting in the world

[lyric kestrel]

Could be surrounding chunks at the edge loading?

But I mean, 2GB only isn't really bad at all

[fallow minnow]

i think what ill do is

[lyric kestrel]

Bedrock Debugger tells me I use 3GB on a superflat world

[fallow minnow]

so i publicly exposed my bridge for discord to minecraft and my database

im just going to host the server on another vps

and talk to this other one

and then just closely monitor the one with the bds on it

but i honestly think its just caching minecraft stuff

chunks and what not

went from 925 to 913

[lyric kestrel]

Could be

[fallow minnow]

2.44 gb to 2.41

back up to 2.44

[lyric kestrel]

Ye, that's not bad at all

That's just usual

[fallow minnow]

i dont mind the steady growth as ill reset the server every few hours either way

[lyric kestrel]

Just leave it up for a few hours and see how high it goes

[fallow minnow]

but as long as its not like consistantly just going up

[dusky flicker]

seriously, its not an addon that will make the memory blow

[lyric kestrel]

Ye, I was about to say. Servers usually reset themselves every day anyways

[lyric kestrel]

So like unless it's Discord levels of Memory Leakage; it's not really a worry

[fallow minnow]

but yeah its def slowly going up

2.46 now

its like

an oscillation

[lyric kestrel]

Just keep it up for a few hours and see what it goes to

[fallow minnow]

yes

its been running for 1.5 hours now

if i dont exceed 3gb within the next 2 hours ill say its fine

not ideal

but still fine

[dusky flicker]

🧐 bros afraid of using about 3mb

[fallow minnow]

huh

im at 2.43 rn

2.43 gb

so if i get to 3 thats what like

570mb

yeah its like oscillating

just a trend upwards

[lyric kestrel]

@fallow minnow how is it now?

[fallow minnow]

sitting at 2.51 gb

interesting

oof now at 2.54

[lyric kestrel]

What does RSS mean?

But ye, it seems like there is a little bit of memory leakage within it

But it doesn't seem that bad

[fallow minnow]

like how much memory that process is using

[near aspen]

Hello👋
Just a short question: I have an item that I want to use with right click on an entity. If I wanted to use the playerInteractWithEntity, it would only count, if I interacted with the villager trading menu for example right?
So if I just wanted to use my item, I would have to use itemUse and than get the entity within the viewing direction of the play?

[ocean escarp]

Is there any way to grab entity lore from a script to test against a different value?

[warm mason]

entities can't have lore

[ocean escarp]

Aren't items on the ground entities tho?

[ocean escarp]

We are trying to pretty much read a value off a spawned item

Can we access data with scripts?

[winged drift]

entity.getComponent("minecraft:item").itemStack.getLore() should work

[ocean escarp]

[object undefined]

Or however it goes

The code is from my friend but they're too shy to post apparently

world.afterEvents.entitySpawn.subscribe((ev) => {
    world.sendMessage(toString(ev.entity.nameTag))
    world.sendMessage(toString(ev.entity.typeId))
    world.sendMessage(toString(ev.entity.getComponent("minecraft:item").itemStack.getLore())) 
    world.sendMessage("vulsmells") //very original ik
})

[warm mason]

what is toString?

and this should work

[ocean escarp]

converts value to a readable string?

[dusky flicker]

.toString exists bro

[ocean escarp]

Tried and it threw errors

[dusky flicker]

what exactly did it throw?

[winged drift]

maybe the item dosen't have a lore

that would throw errors

[ocean escarp]

I guess they didnt have an exception case

[ocean escarp]

Something about invalid conversion or something I don't exact have the error in chat to look at rn

[remote oyster]

world.afterEvents.entitySpawn.subscribe((ev) => {
    const entity = ev.entity;

    world.sendMessage(entity.nameTag);
    world.sendMessage(entity.typeId);

    const itemComp = entity.getComponent("minecraft:item");

    if (itemComp) {
        const lore = itemComp.itemStack.getLore();
        world.sendMessage(lore.join(", "));
    }
});

You don't need to convert to a string when it already returns strings.

[ocean escarp]

Ah

[remote oyster]

Also, the method used to convert to a string was incorrect.

[ocean escarp]

Appreciate it but I'm already pondering alternative methods.
Can you distinguish between the item name and identifier in scripts easily?

[remote oyster]

Yes

[ocean escarp]

Because I was thinking of making a custom item that summons whatever it's named before deleting itself

[remote oyster]

Just have to read the string and verify if it's what you are seeking.

[ocean escarp]

test:mob_summoner

check name;
if not real return;
summon entity;
kill self;

[remote oyster]

That's the gist of it.

The logic and condition will be up to you.

[woeful vine]

Hey! Someone know why scripts don't work on realms and how can I make them work?

[fair quarry]

Scripts works on realms, there's some exceptions, But we have no way of knowing unless you provide more information.

[woeful vine]

I am using beta apis, I am using 32 java script files (doesnt matter, even a behaviour with just a script with console.warn wont work), format version 2

Idk what you need to knwo, but Ill provide it to you.

Send manifest.json

And console errors if possible

[fair quarry]

Hmm gimme a sec

[woeful vine]

Aight

Working now

WTF

Like, it just started working

I changed nothing

[fair quarry]

lmao

next time check if the addon is added using /packstack server verbose exclude-vanilla

[summer cloud]

how do i create a itemStack of potion tipped arrows?

[untold magnet]

yao, my xCore addon (that has all of my addons functionality) has 49 dynamic properties and its total bytes count is 1455, is it fine? like when should i start caring about the dynamic properties impact on performance?

[distant tulip]

if you are not getting a warning you are fine

[distant tulip]

not possible afaik? maybe with commands

[summer cloud]

thats what i figured, its just a big pain to do it via commands

[distant tulip]

this is stupid

[fallow minnow]

@lyric kestrel alright so bad news @dusky flicker

dont mind the 0.01mb / hr, its actually aroumd 50-50mb/hr

although after around 8 hours the mem didnt reach 3gb its itll not good

def a leak

[dusky flicker]

theres leak

but damn

it not that much

[fallow minnow]

yeah

its just weird though

[dusky flicker]

but it could be good enough for you to study

have you got any idea of where it could be?

[fallow minnow]

nope 😭

the biggest thing i store is player data

[dusky flicker]

i dont know exactly how to measure memory usage

[fallow minnow]

could it be like

tsc watch?

actually no

im going to try something

if its my scripts

[dusky flicker]

im checking it

[fallow minnow]

ill know if i reload and it drops

[dusky flicker]

ur running on windows?

[fallow minnow]

linux

[dusky flicker]

thank god

[fallow minnow]

im gonna reload and see

praying its just minecraft itself

[dusky flicker]

theres valgrind

im checking gpt

by the way

[fallow minnow]

okay rip it def is my code prob

after reload it dropped to freaking

1231291 node 644432 8.1

jeesususuususuu

2.16gb

okay im going to check through every single file

[dusky flicker]

try using valgrind for so

im checking it

seems to be interesting

[fallow minnow]

which never gets set to the cache again

[dusky flicker]

as json?

[fallow minnow]

yes just for testing

well so

its stored as sql columns

and i just convert to json structure and cache it

[dusky flicker]

oh, so its not bad as i thought

i thought you were using json as db

[fallow minnow]

yeah noo

😭

but i 100% have a leak

which wil be so annoying to find

[dusky flicker]

cant you show the code?

so i can check it

and try to help to find out

[fallow minnow]

wellll

its a lot

[dusky flicker]

as long as its understandable

its not a problem

[fallow minnow]

okay MIGHT have found it

[dusky flicker]

what do you suppose its?

[fallow minnow]

this

const from = { x: -370, y: 82, z: -38 };
const to = { x: -364, y: 75, z: -37 };

const volMin = {
    x: Math.min(from.x, to.x),
    y: Math.min(from.y, to.y),
    z: Math.min(from.z, to.z),
};
const volMax = {
    x: Math.max(from.x, to.x),
    y: Math.max(from.y, to.y),
    z: Math.max(from.z, to.z),
};

function isInsideBlock(pos: Vector3) {
    return new BlockVolume(volMin, volMax).isInside(pos);
}

const island = new IslandManager();
const handledPlayers = new Set<string>();
const lastInside = new Map<string, boolean>();
system.runInterval(() => {
    for (const player of world.getPlayers()) {
        const xuid = player.xuid;
        const insideNow = isInsideBlock(player.location);
        const insideBefore = lastInside.get(xuid) ?? false;
        lastInside.set(xuid, insideNow);
        if (handledPlayers.has(xuid)) continue;
        if (!insideBefore && insideNow) {
            handledPlayers.add(xuid);
            (async () => {
                try {
                    const hasIsland = await island.has(xuid);
                    if (!hasIsland) {
                        await islandSelection(player);
                        return;
                    }
                    island.teleport(player);
                } finally {
                    handledPlayers.delete(xuid);
                }
            })();
        }
    }
}, 20);```

oka nvm not that

[dusky flicker]

lastInside would yeah start to grow because it doesnt clean up

[slow walrus]

you could probably remove the lastInside map entirely, since you already return if handledPlayers has the xuid, which is set once they're inside

[fallow minnow]

currently im converting like everything over to my actual cache that i forgot to never use!

so its just a whole bunch of random maps and sets and etc

[remote oyster]

Memory leaks are fun 😜

[fallow minnow]

genuinely have no idea what its from so

but im switching over ALL of my registries and everthing to my cache class

then we will see

[remote oyster]

That code you shared has a memory leak with lastInside. That map gradually accumulates data and when players leave or disconnect that data isn't being cleaned up.

[fallow minnow]

yeah i changed it to just automatically delete the players lastInside after it completes

[remote oyster]

I'm sure you got a lot of code to look at but anything storing data in memory needs to be verified if that memory is being handled in cases where the data is no longer relevant. Such in cases where a player leaves or disconnects.

Memory should be temporary storage, not permanent.

[fallow minnow]

well

the only memory i store for the player is their island data and player data

which are both deleted after they leave

but i also cache things like

cosmetic entries from my database, registered enchants, registered generators, quest templates, command registry, reward templates

[fallow minnow]

okay i fixed everything to use the cache thing i have and hopefully fixed the memory leaks

looking good so far

[sly valve]

yo

Is there a list of every API Error? (like ReferenceError: Native function [Class::method] does not have required privileges)

[severe forge]

Is there a way to get the player's skin by scripting?

[cold grove]

check in the docs if the method cannot be run in read-only mode

for example before events

[sly valve]

? I am searching for a list showing every API error, this was just an example

[wary edge]

Are you looking for the specific message or instances of throwing errors?

[sly valve]

Basically for a list providing every possible API error (such as the one I provided)

But I doubt I might find anything

[sly valve]

Message content and error type

[wary edge]

Error type you can look at the docs or npm types. Message, I dont know if theres a public one, you'll have to test in game.

[sly valve]

Thanks, Appreciate it

[sly valve]

Oh if you dont mind me asking, there is an error when you try executing something in the early-execution mode. when a function doesnt explicitly says "This function can be called in early-execution mode" it means they cannot be run in this mode. right?

[wary edge]

Correct.

[sly valve]

By any chance, do you know the thrown Error instance? I cannot find anything nor test

[wary edge]

Not off the top of my head no.

[sly valve]

Alright, still thanks

[fallow minnow]

@dusky flicker looking good?

its stable hovering for the past 10-20 minutes

thank the lord

[fallow minnow]

nvm it just keeps steadily growing

this is so weird

[light nest]

can script detect block's collision? example if a block has a collision size not more than [8, ~, 8] then it will return true

[cinder shadow]

we can't cancel the message for when a player joins the world right?

[fallow minnow]

no sadly

what i did is uh

i used json ui and just hid the "joined the game"

or world

BUT ive noticed something weird.

since ive "disabled" the join message, scripts still sometimes duplicate it..?

its very strange

[cinder shadow]

ah.. I'll see what happens when it's disabled in my game then

I finished implementing a friends list system and now it's kind of weird since there are double messages

which just defeats the purpose of a friends list

beyond this

[sly valve]

Minecraft Bedrock API in a nutshell

[fallow minnow]

yeah its really random like the normal vanilla join text

i can leave and join a whole bunch and itll just randomly duplicate when sending the message with player events after spawn

[sly valve]

Did Microsoft already switched from UWP to SDK? Last time I checked was a year ago

[fallow minnow]

GDK

yes

a lot buggier now tbh

[sly valve]

YaY

Aww

[fallow minnow]

but not too bad

i get some weird texture bugs

where textures just like

[sly valve]

Thanks Microsoft for nothing but bugs

[fallow minnow]

replace eachother or just disregard what ive changed in my rps

[sly valve]

I hope the CEO of Microsoft gets replaced

[fallow minnow]

😭

[sly valve]

See the positive~

[fallow minnow]

also i pinpointed my MEMORY LEAK / ALLOCATION CHURN thing 😈 😈 😈

[sly valve]

I wrote my own Server module API because I cant play MCBE Win

[fallow minnow]

it was my wind thing which checks the surrounding chunks around the player and randomizes wind speed with weird noise

and my sidebar??

i guess

i was being stupid and umm

i was spam showing the sidebar every tick WHILE getting the players ping every single tick

[sly valve]

WHAT

[fallow minnow]

which returns a promise

[sly valve]

AHHHHHHH

UNOPTIMIZED CODE

[fallow minnow]

i didnt know it was that bad 😭

im using endstone so

i dont normally have access to ping

but i was also calculating the tps and displaying it every tick

[sly valve]

I feel bad for your IDE

oh and your kernel

and your cpu

and your hdd

and ram

[fallow minnow]

my cpu is fine tbh

im honestly thinking about just hosting everything on this vps

its only $4.90

4vCores, 8gb ram, 75gb ssd

[sly valve]

yeah, let your pc rest

anyways gtg, I spent the last 10 hours with no sleep on something stupid

[fallow minnow]

same

like 15 hours just graphing memory usage

💀

[sly valve]

-# i wrote my own server module API

hmh, progamming

needs to get longer tbh

gnn

[dusky flicker]

what was it? seems to be better than before

[fallow minnow]

my wind system and sidebar i guess

😭

i tested the same way by just sitting in the world for an hour and i disabled my wind interval and sidebar interval

only ~50mb /hr

which seems normal

[dusky flicker]

no way how was a wind system having leak

[fallow minnow]

IDK 😭

it was like

[dusky flicker]

xd

[summer cloud]

is there a way to put dynamic values into command selectors?

[fallow minnow]

it was allocation churn

i was at like

like 150-200mb /hr

now its at 55

it does go up but not enough for me to optimize more

and its most likely just minecraft doing whatever it does

[dusky flicker]

weird how minecraft can't find the memory leak by itself

i think they should add a flag or something to stop the addon or something

when the memory increases

[fallow minnow]

or if they could just document how to connect the uhh

whatever its called

[dusky flicker]

profiller?

[fallow minnow]

yeah

i cant seem to link it with my vps

[dusky flicker]

man as far as i used it

[fallow minnow]

i did port 19144 vps ip

i opened up the port just to test

wouldnt work

nothing

[dusky flicker]

first i start it on the vscode with listen if im not mistaken

[fallow minnow]

yes

[dusky flicker]

and on minecraft connect it to the same port

[fallow minnow]

yeah but it just doesnt work 😭

[dusky flicker]

but i use the terminal

[fallow minnow]

oh i used that weird json thing

[dusky flicker]

so minecraft is forcing me to use vscode

like seriously

why mojang? 😭 why?

[sly valve]

want to use Notepad++ instead

[dusky flicker]

these days im using zed and helix

but notepad++ isnt bad at all

[dusky flicker]

by the way

cant you open some issue or something like that

to ask mojang to detect when an addon uses too much memory?

[sly valve]

iirc there is an "setting" for it

[subtle cove]

on custom commands, not possible atm

[fallow minnow]

is there a way to lessen the amount of entities that spawn from spawners?

like lessen the time

or something

[dusky flicker]

how do i get custom component information from an item?

i mean, not necessarily it being on a event executed from a custom component

[wary edge]

getComponent(your custom component)

It should return a customComponentInstance and you can get tge parameters.

[dusky flicker]

thanks my friend

[sly valve]

Gmorning

[zinc breach]

can you access dynamic properties in the world file

like see all the dynamic properties that were set on your world

[sly valve]

I think yes by using NBT tools or something, check Google for it

[unreal saddle]

Does anyone know why the script only works for me, but my friend gets this error every time he's hit by the entity I assigned?
[Scripting][error]-Error: Failed to resolve identity for 'GroberPC3843'. at <anonymous> (custom/menu_ent.js:139)

This is the code

const statueObj = world.scoreboard.getObjective("statue")
  ?? world.scoreboard.addObjective("statue", "statue");

world.afterEvents.entityHurt.subscribe(ev => {
  if (ev.hurtEntity instanceof Player && ev.damageSource?.damagingEntity?.typeId === "papu:medusa") {


    ev.hurtEntity.dimension.playSound("health_stone", ev.hurtEntity.location);

    let score = statueObj.getScore(ev.hurtEntity) ?? 0;
    score += 1;

    if (score > 20) score = 20;

    statueObj.setScore(ev.hurtEntity, score); //This is line 139
     ....

[sly valve]

I remember that you grt this error if he doesnt has a score

Make sure his score is at least set to 0 before getting it

Maybe write a function to get a certain score and use try catch

[winged drift]

I can't remember ever getting an error from that

[sly valve]

Hmm weird

[sly valve]

Use this

let score = 0
try {
  score = statueObj.getScore(ev.hurtEntity) ?? 0;
} catch {}

Should work

[winged drift]

The error was at linie 139 tho. Also hasParticipant would be a better way of checking that

[sly valve]

True, I am on phone right now, may you write him a getScore fn ?

[unreal saddle]

You were right, I added at least 0 points and it started working

[winged drift]

Weird. Never had that issue.

[sly valve]

Well maybe because your users always had a score

[winged drift]

I tested it without score and it worked

[sly valve]

When you create a scoreboard no one has a score until you add/set it to 0 or else

[sly valve]

Huh weird

But good to know, because I am writing my own Server module API (cant play Mcbe and got bored)

[subtle cove]

That errors comes from the entity having no ScoreboardIdentity like player.scoreboardIdentity is null where the entity currently has no score from any objective

Doing hsParticipant will try to look for the identity, which will make that error again.
But when entity is already a participant of other objective, hasParticipant will never throw

[hybrid bobcat]

Has anyone experienced an issue where reducing the damage below 1.0 in world.beforeEvents.entityHurt prevents the hurt entity from receiving invulnerability frames?

here's my code just in case someone want to test it

import { world } from "@minecraft/server"

world.beforeEvents.entityHurt.subscribe((event) => {
    event.damage *= 0.5
    world.sendMessage(`Damage: ${event.damage} || ${Math.random().toFixed(1)}`)
});

[cinder chasm]

Is it possible to make the costume block spawn XP by breaking it cuz I tried in the behavior pack and script and loot table ?

[fallen cape]

you should be able to spawn the xp entity in a playerBlockBreak event

[cinder chasm]

I don't know how

[sly valve]

By using the Dimension class your can use the summonEntity or spawnEntity method

Im not sure currently, better check the docs or try finding it when you have the npm installed

[dusky flicker]

"myaddon:modular_item": {
        "range": 80,

          }
        }
      }```

Is this organized enough?

just setup a 'module' inside the component, and thats it, you ready to go

[dusky flicker]

no way '-'

why in hell would they limit the depth of files?

[wary edge]

For performance reasons, custom components are limited to a depth of 2.

[dusky flicker]

🧐 no way they dont cache the objects

[dusky flicker]

i might have to think in a better solution for this then

damn i never thought id need to use dod knowledge in json

[sly valve]

Hello!

When does startup gets called and when worldLoad
is there a static sequence?

[wary edge]

Startup gets called before worldLoad

[sly valve]

And after the "tick" ticks?

Any way to fix this so it looks for an exact match and not whether it just includes the value

We are using Includes because getLore by itself wasn't working

[somber rapids]

with includes it doesnt check if it only has those, but if it has those alongside anything else. Right now the problem is i dont know how the getLore returns its value, and the variants i tried didnt work

[winged drift]

Check for lenght too or compare .join().

[somber rapids]

ngl the values being returned are js annoying, i'm tryna get a different thing working but it aint, even though it allows me to use the value as a string later in my code with no issue
world.sendMessage(ev.entity.getComponent("minecraft:item").itemStack.nameTag)

[somber rapids]

the length could work, but only if i figure out what the length actually is.
besides, knowing the returning format would just be overall useful for later things were i to use lore

[winged drift]

getLore(): string[];

[cinder shadow]

exact match of what? Right now you're looking for an exact match of "Usage: Rename with [entityName] [count] [nameTag]"

[ocean escarp]

I thought "includes" just means it has to contain the phrase somewhere in the output not that it has to be an exact match

[cinder shadow]

Sorry, it does, but why are you looking for a string like that

If you want an exact match, just do loreString === "Expected String"

[ocean escarp]

We have this item that pretty much acts as a better spawn egg but we couldnt test typeId for some reason, so we resorted to testing for the lore that tells you how the item works

Since no other would have the same lore

[marble sigil]

Is it possible to make a particle size bigger or smaller by spawning via Scripts?

Performance matters btw.

[thorn flicker]

yes, with MolangVariableMap, you can create a variable in scripts to use in the particle json file

https://stirante.com/script/server/2.5.0/classes/MolangVariableMap.html

[marble sigil]

and then I use like v.name to access?

[thorn flicker]

yes

[marble sigil]

like if I .setFloat("r",5), then v.r in the particle json is 5?

[thorn flicker]

mhm

[round bone]

Yes

[marble sigil]

Okay ty I figured out 😌

[thorn flicker]

mhm means yes

[marble sigil]

good to know

[untold magnet]

i somehow managed to do this:

[untold magnet]

and i made it even better,

@distant tulip this is what i meant by 'detecting when the player jumps'

[distant tulip]

there is an evemt for that if it is not what you are using

[untold magnet]

what kind of event is that?

[distant tulip]

PlayerButtonInputAfterEvent

[untold magnet]

nope, that doesnt work properly, it cannot detect when the player entity jumps as u can see in the video

it will only detect when the button is pressed or hold,

[untold magnet]

https://discord.com/channels/523663022053392405/1476541799098093619

[distant tulip]

you are overcomplicating things

[untold magnet]

how is my code overcomplicating while this one exist? https://discord.com/channels/523663022053392405/1264459228521959425

[distant tulip]

the event is new

[warm mason]

just add a player.isJumping condition

[untold magnet]

well, try making one that isnt overcomplicating and works better than the one i made,

[distant tulip]

.

[untold magnet]

import {world, system} from '@minecraft/server';

export const ePlayers = new Set();

world.afterEvents.playerJoin.subscribe(({playerId}) => {ePlayers.add(playerId)});
world.afterEvents.playerLeave.subscribe(({playerId}) => {ePlayers.delete(playerId)});

system.runInterval(() => {
    for (const ID of ePlayers) {const player = world.getEntity(ID);
        if (!player?.isValid) return;
        if (player?.isJumping) console.warn('jump')
    };
});;```

[untold magnet]

@distant tulip.

-# unless if im doing it wrong and i have no clue how it should work,

[distant tulip]

bro,,,
runInterval is not the way

[warm mason]

it's isJumping, not hasJumped

[warm mason]

actually, the method with input button won't work with auto jump

[untold magnet]

how else am i suppose to make it work then?

if i already did make it work https://discord.com/channels/523663022053392405/1476541799098093619

[distant tulip]

you use the event to start the interval and clear it when unPressed

[untold magnet]

just.. show me an example of that work, or just send me the script so i can test it out

[warm mason]

/** @type {Record<String, import('@minecraft/server').Player>} */
const PlayersMap = {};

/** @param {WeakSet<import('@minecraft/server').Player>} */
const PlayerHasJumped = new WeakSet();

world.afterEvents.playerSpawn.subscribe(data => {
    if (data.initialSpawn) PlayersMap[data.player.id] = data.player;
});

world.afterEvents.playerLeave.subscribe(data => delete PlayersMap[data.playerId]);

system.runInterval(() => {
    for (const player of Object.values(PlayersMap)) {
        if (!player.isValid) continue;

        const isJumping = player.isJumping; const hasJumped = PlayerHasJumped.has(player);

        if (!isJumping && hasJumped) PlayerHasJumped.delete(player);
        else if (isJumping && !hasJumped) {
            PlayerHasJumped.add(player);
            console.warn('jump');
        }
    }
});
``` not tested

[warm mason]

nah, still won't work. Auto jump doesn't trigger button input event so u won't be able to detect it and interval is useless here

[untold magnet]

doesnt work properly,

[warm mason]

hmmm

[untold magnet]

works perfectly fine when u press the jump button,

[distant tulip]

ah, i thought you are referring to when the player continue on pressing the jump without releasing

[untold magnet]

lemme test my one with auto jump

[warm mason]

needs to add isOnGround condition too...

[warm mason]

/** @type {Record<String, import('@minecraft/server').Player>} */
const PlayersMap = {};

/** @param {WeakSet<import('@minecraft/server').Player>} */
const PlayerHasJumped = new WeakSet();

world.afterEvents.playerSpawn.subscribe(data => {
    if (data.initialSpawn) PlayersMap[data.player.id] = data.player;
});

world.afterEvents.playerLeave.subscribe(data => delete PlayersMap[data.playerId]);

system.runInterval(() => {
    for (const player of Object.values(PlayersMap)) {
        if (!player.isValid) continue;

        const isJumping = player.isJumping; const hasJumped = PlayerHasJumped.has(player);

        if (hasJumped && (!isJumping || player.isOnGround)) PlayerHasJumped.delete(player);
        else if (isJumping && !hasJumped) {
            PlayerHasJumped.add(player);
            console.warn('jump');
        }
    }
});
``` try this

[untold magnet]

my system is kinda bugged when falling from a block, but works perfectly fine with auto jump

hmm

[warm mason]

that's how isJumping works.. u can add a test for vertical velocity

[untold magnet]

its bugged under slab

[warm mason]

?

[untold magnet]

spam the event while standing below a slab and holding the jump button

[warm mason]

ohh

Well I tried...

[untold magnet]

and my system is now even better lol

[untold magnet]

import {world, system} from '@minecraft/server';

const jumpCache = new Map();
export const ePlayers = new Set();

world.afterEvents.playerJoin.subscribe(({playerId}) => {ePlayers.add(playerId)});
world.afterEvents.playerLeave.subscribe(({playerId}) => {ePlayers.delete(playerId); jumpCache.delete(playerId)});

system.runInterval(() => {
    for (const ID of ePlayers) {const player = world.getEntity(ID);
        if (!player?.isValid) return;
        const yVelocity = player?.getVelocity().y;
        const hasJumped = jumpCache.get(player?.id) ?? 0;

        if (player?.isOnGround) jumpCache.set(player?.id, 0);
        if (!player?.isOnGround && yVelocity > 0 && hasJumped === 0) {jumpCache.set(player?.id, 1); console.warn('jump')};
    };
});;```final results

now falling from blocks doesnt count as jumps,

[untold magnet]

and that doesnt work with auto jump,

[dusky flicker]

yeah you did overcomplicate it

you could simply check when the player presses to jump

and check if hes on the ground

[untold magnet]

-# auto jump...

[dusky flicker]

-# why writing like this?...

[untold magnet]

bec auto jump cannon be detected via the button inputs

[dusky flicker]

i just dont think it checking the y axis of the player velocity is a good way to do so

[untold magnet]

ill do some improvements, like it might return jumping while climbing scaffoldings or ladders,

[warm mason]

😭

[untold magnet]

i haven't tested those things yet

[dusky flicker]

i mean, i personally, prefer that working properly but unable to check some specific occurs, such as auto jump, rather than being buggy and checking when i dont want to

[untold magnet]

for me, i do need to detect everything for my stamina system,

[dusky flicker]

i'd rather focus on implementing other systems on top of the stamina one

and then improve the way the stamina system works

[somber rapids]

if setlore() requires an array, how does it return the value in getlore()?

[warm mason]

It returns an array of string

[somber rapids]

how can i read it as an array to see if the whole array matches another?

so far i tried to and either i did it wrong, or its not reading as an array

[fiery solar]

You have to check every element of the first array and compare it to the value of the second array

function arraysEqual(a, b) {
  if (a === b) return true; 
  if (a.length !== b.length) return false;
  
  return a.every((value, index) => value === b[index]);
}

[ocean escarp]

If standard Null / undefined checks aren't working. What could be a possible cause?

[fiery solar]

Do you mean you're trying to check if an item has no lore?

How are you checking? getLore returns an array, so if an item has no lore it will give you []

But you can't check if the lore === [] because that's always going to return false. Equality checks on arrays in JavaScript don't check that the value of the arrays are the same, they just check if the two sides of the equals sign reference the same array.

That's why [] === [] is always false.

[ocean escarp]

We tried to move to a name based system and null checking was a pain

Im ngl the code is so ugly rn and I would fix it myself if I had the skill but it's a joint project and I'm more just the gameplay designer guy

[fiery solar]

Can you explain more about what you're trying to do? There's almost definitely a better way to do it than using lore

[ocean escarp]

Since we can't run mob summons in loot tables we are trying to make an item that does that
If it exists in the world it'll check its name and use this formatting to summon entities

<typeId / name> <amount> <nameTag>

[somber rapids]

rude

i made that code

world.afterEvents.entitySpawn.subscribe((ev) => {
    if (ev.entity.typeId == "minecraft:item") {
        const name = ev.entity.getComponent("minecraft:item").itemStack.nameTag ?? "null"
        const lore = ev.entity.getComponent("minecraft:item").itemStack.getLore()
        const type = ev.entity.getComponent("minecraft:item").itemStack.typeId
        const spawner = name.split(" ")
        if (type == "cnr:omnispawner" && name != "null") {
            if (name.includes(" ") && spawner.length > 1 && isNaN(spawner[1]) != true) {
                const count = Math.min(Number(spawner[1]),64)
                if (spawner.length == 3) {
                    for (let i = 1; i <= count; i++) {
                        try {ev.entity.runCommand("Summon " + spawner[0] + " " + spawner[2])} 
                        catch {ev.entity.kill()}
                    }
                    ev.entity.kill()
                } else{
                    for (let i = 1; i <= count; i++) {
                        try {ev.entity.runCommand("Summon " + spawner[0])} 
                        catch {ev.entity.kill()}
                    }
                    try {ev.entity.kill()} catch{}
                }
            } else {
                try {ev.entity.runCommand("Summon " + spawner[0])}
                catch {}
                ev.entity.kill()
            }
        }
        else {
            if (type == "cnr:omnispawner") {
                ev.entity.kill()
            }
        }
    }
})```

[ocean escarp]

I just meant it can be compacted

[warm mason]

why do you need lore then?

[ocean escarp]

Cause we had trouble testing names before, it's fixed

now it's just code compaction, we figured it out while looking for the solution (crazy I know)

[warm mason]

well, its very easy to do then..

[small depot]

you can use the minecraft debugger

and start testing your files one by one

unless you have any clue of what is causing the memory leak

[distant tulip]

there is memory usage there iirc

[small depot]

it could be variables, maps, jobs, or promises accumulating

[small depot]

yea but i think it doesnt tell you what exactly is using that memory

[warm mason]

const EntitySpawnerItemId = "item_type_id";

world.afterEvents.entitySpawn.subscribe(data => {
    const entity = data.entity;
    if (entity.typeId != 'minecraft:item' || !entity.isValid) return;

    const item = entity.getComponent('item')?.itemStack;
    if (item.typeId != EntitySpawnerItemId) return;

    const dimension = entity.dimension;
    const location = entity.location;
    entity.remove();

    const spawnerData = item.nameTag.split(' ');
    const spawnAmount = Number(spawnerData[1]) * item.amount;
    const spawnTypeId = spawnerData[0];
    const spawnNameTag = spawnerData[2];

    for (let i = 0; i < spawnAmount; i++) {
        const spawnedEntity = dimension.spawnEntity(spawnTypeId, location);
        if (spawnNameTag) spawnedEntity.nameTag = spawnNameTag;
    }
});
``` try this

and change EntitySpawnerItemId to your item type id

[somber rapids]

it works, but not without preventing some issues i was hoping to cover

specifically instances such as this, where some arguments are correct, and others arent
my own code ensured that as long as the first argument was correct, the others either would be ignored, or would adapt (so if it was the below image, it would spawn a skeleton with name "aa" rather than just nothing at all)

i'm pretty impressed with the code you gave, so while i could modify it to add these exceptions, im sure that my changes would probably make it look just as bad as before

out of curiosity, why is there a semicolon on every line?

[open urchin]

Semicolons separate statements
Line breaks can also implicitly separate statements in JavaScript so having them at the end of lines is optional but I prefer having them personally since it makes copy/pasting easier

[lyric kestrel]

Ye, in other languages it'd be needed, but JS has something called "Automatic Semi-colon Insertion"

So when the compiler is compiling, it automatically inserts ; after statements

[sharp elbow]

Automatic semi-colons are a nice convenience but explicit is always better IMO. There are a couple of cases where newlines don't delimit meaningful tokens like you would expect, and placing a semi-colon manually would change the behavior

[somber rapids]

makes sense, i knew semi colons separated ones on the same lines, but line breaks combined with them seemed odd at first

[somber rapids]

kinda curious what that would be now...?

[sharp elbow]

In a case like this, ASI cannot determine if the object literal (in parantheses) on line 3 should be its own statement, or if it is a function call on the variable a:

var a = "hi"
a
({foo: bar})

[somber rapids]

that kinda makese sense, but what is a doing there anyway?

[sharp elbow]

It'd happen mostly where you're preparing code and might erase something, making a typo. I've needed to wrap object literals in parentheses for arrow functions and encountered something like that before

This may be a bit more demonstrable:

var a = {"hi"() {return 1}};
const b = a["hi"]
(a.hi() + 3).toFixed(2)

Should b be assigned to the method "hi" on a? Or should it be the result of calling "hi" on a?

Of course, erasing the parentheses on line 3 could solve this too.
Edited it to include an example where that is less trivial of a solution

[dusky flicker]

why exactly would it execute a function call implicitly?

[sharp elbow]

If I replace the line breaks with spaces, it becomes more apparent:

var a = {"hi"() {return 1}}; const b = a["hi"] (a.hi() + 3).toFixed(2)

the JavaScript engine assumes a["hi"] (...) is an invocation, since it looks like an invocation

(It's probably a bit more technical than that if you want to get into operation sidedness, but that's the intuitive answer to me)

[dusky flicker]

holy hell

that makes sense

1 more reason i hate js

[round bone]

In my opinion, I don't really care about these features. Good JavaScript developer will switch to TypeScript and keep his code organized anyways, these code snippets are a good example why some people shoudn't even touch this language

It's not the best for every single thing on this planet, but it gets job done and even the biggest companies like X (Twitter), Adidas, Uber, LinkedIn use it on backend

[dusky flicker]

i think the main reason for so its because JS(and consequently Ts) is easy to be used

and to learn as well

so you wont pay as much as you'd for C devs for example

i mean, here on brazil i've seen a job vacancy for rust, about 20k BRL, in dolars right now it might be around 4K, but for us that amount is insane, since the minimum wage on brazil is around 1500 brl

in general for js here i see at most, 7k brl

[round bone]

Web development in general is mostly less worth than Rust and some other niche languages like Elixir

[summer cloud]

Whats the default particle minecraft uses for death, im replacing it

[untold magnet]

current downsides:
breeze-balls when used to launch the player, it will detect the launch as a jump,
getting hit by a mace that has density (that will launch u in the air) will also be detected as a jump, basically anything that makes u leave the ground (besides riding a mob or ender pearls or /tp) will be counted as a jump,

is there other ways that makes u no longer onGround?

elytra doesnt count bec u have to jump to activate it,

[dusky flicker]

i mean, is just autojump that isnt tracked by the player input?

if so

you can do a system that you check the velocity of the player

and check the position near him

[untold magnet]

getting a vertical knockback will count, like from explosions will count as a jump

[dusky flicker]

i mean

if the player did get y velocity, very close to a block

a single block i mean

you emit the event

and the rest keep as input
