Script API General

[fallow minnow]

im about to fully restart the vps so i can use docker

i have so much random stuff on it 😭

and docker is so nice

[round bone]

It's very common, and also nice at the same time

😉

[fallow minnow]

yeah its so easy to run multiple things at once

so i dont have to use pm2

but i will only use docker for the database and othe rmisc stuff

i think i should run a discord bot and the bds on pm2 just for easy production

[fallow minnow]

does script api have access to process env?

[round bone]

Nope, it does not :/

The closest thing are server's secrets

[supple perch]

yoo

i haven't scripted in a while

hope y'all are doing nice

so anyone know how many ticks i have to wait before a chunk is loaded by a ticking area command?

[wary edge]

Any reason you're using commands and not the ticking area manager?

[supple perch]

there's a ticking area manager?

wow

got a link to the docs?

[wary edge]

https://stirante.com/script/server/2.6.0-beta.1.26.0-preview.26/classes/TickingAreaManager.html

[supple perch]

thanks

[honest spear]

Nice

[untold magnet]

so, im making my entity summons other entities close to it, and its showing alot of logs when the entity is not loaded or the spawning area is inside an unloaded chunk, so how am i going to detect if the spawning location is valid or not?

[fallow minnow]

chunk.isvalid or something

and entity.isvalid

[wary edge]

dimension.isChunkLoaded

[untold magnet]

if (dim?.isChunkLoaded({x:dX, y:dY, z:dZ})) dim?.spawnEntity('xhardercore:ender_bullet_rain', {x:dX, y:dY, z:dZ}); should do it ig,

what i should do is adding a limit to the amount of mobs it will spawn, so it wont really not spawn anything by leaving the entity inside the unloaded chunks, like it waits for the chunks to be loaded to spawn the entities.

but wait, that means there will be a runinterval that detects the loaded chunks, which is not great for TPS, so i think ill just remake the idea or something

[untold magnet]

yeah, i just tested it out, the way it spawns those entities are just too bad, so i have to remake it completely.

[native osprey]

has someone managed to do a right click run command on item that can spare some code?

[round bone]

import { world, Player } from "@mincraft/server"

world.afterEvents.itemUse.subscribe(({ source, itemStack }) => {
    if (source instanceof Player) {
        switch (itemStack.typeId) {
            case "minecraft:stick":
                source.sendMessage(`${source.name} has used a stick!`)
                return
        }
    }
})

[native osprey]

Okay, if im reading correctly... This is to stack an item after it was used, am i correct?

[round bone]

This sends a message to a player that they've used a stick.

[native osprey]

Oh ok, hmm, there is a way to replace sendMessage with running a function or not?

Like the idea i have is creating a magic system that uses a staff as the running object and depending on the offhand item it runs a different spell

[snow knoll]

runCommand

But you should really just read the documentation to see what you can do with what

[native osprey]

Thanks, im really trying but its hard to see which custom component to use

[snow knoll]

Not everything is a custom component

[native osprey]

It isnt?

[snow knoll]

This is just a scripting method

And the script is just an event

[native osprey]

No wonder why i was lost

[snow knoll]

Understandable, things are a little hard to understand at first but its really good your addon when you get the hand of it

[native osprey]

Yeah, tbf i had no idea of scripting until like 2 weeks ago...

[snow knoll]

Late to the party, I see (I was too but we all got to start somewhere)

Want an explanation of the way these things work
By these things, I mean events, custom components, classes and objects?

[native osprey]

Yes! Please 😭

Im so lost now

[native osprey]

okay im here... i have to replace surce.sendMessage with runCommand right?

[round bone]

Yes

import { world, Player } from "@mincraft/server"

world.afterEvents.itemUse.subscribe(({ source, itemStack }) => {
    if (source instanceof Player) {
        switch (itemStack.typeId) {
            case "magic:elemental_staff":
                source.runCommand(`say test!`)
                return
        }
    }
})

Did he hit his had?

[native osprey]

with this i can then make it run a function and in the function create all the different cases

[native osprey]

hit his had?

[honest spear]

i am refering to the gift you send

[native osprey]

oh, maybe, i was trying find a similar one

[snow knoll]

Basically:

• Events are listeners that set of when subscribed to with code used. They come in the form of either a beforeEvent or an afterEvent, which run the code either before or after the actual event occurs in-game. If using a BeforeEvent there is the chance of being able to cancel the event from occurring, which would stop the effects of the event from happening. For example, canceling the itemUse beforeEvent would prevent an item from being used
• Custom components are simplified events, of which you can access event handler functions, like onUse, and work in a similar way to events, designed yo be more beginner friendly and more reliable (so I've heard)
• Classes are representations of the state of any given thing in the game. A thing being sonething like items, the world, blocks, dimensions, players, and more (those are some of the most important ones, though)
• For each of these classes, an object is the actual instance of said class, for example, an object of the item class is a real item, an object of the entity class is a real entity, an object of the player class is both an object of the player and entity classes, since the player class extends/adds onto the entity class

[native osprey]

oh! thanks that helps, now it makes more sense now

i have another question then, is possible to add another event in here right?

in this case to add cooldown to the object im using i would need to link it with world.afterevents.itemuse?

oh wait...

[snow knoll]

No need for the other event BTW

[native osprey]

yeah i realized, what i meant is that if its possible to have another case type with another item

[native osprey]

in the end i didnt needed it, but how can i add a cooldown to the magic:elemental_staff item?

[cunning canyon]

Should I use arrow functions or normal functions?

I usually always use arrow functions but don’t know why exactly, I just took the advice lol

[subtle cove]

I use arrow functions for higher this use-caseslike inside a class.
It depends on whether u wana use argument or this keywords
i treat it for scope preferences

[sharp elbow]

One major disadvantage to arrow function literals is they have no assigned name. Across larger projects or larger teams, it may not be as easy to navigate stack traces when they frequently say at <anonymous>
Arrow functions have their use yet IMO they are best saved for either object properties (being more like lambdas) or for preserving the this callsite (for classes and similar cases)

[native osprey]

Hi again, so after the help with runCommand i managed to advance a lot on my mod! The only thing left is... How can i add a cooldown... Accidentally... Made a super op attack named "Extermination light" that people can spam ._.

[last latch]

use dynamic properties to set and retrieve their cooldown

if they do have a cooldown, cancel the extermination light

for cooldowns use "Date.now()" to get the current time and add "Date.now() + (1000 * cooldownInSeconds)"

[native osprey]

Um... Can you put it in simpler terms?

I havent modded since 1.15

[last latch]

Not sure how to say it any simpler

hold up gimme a sec

[last latch]

Date.now() returns the time in miliseconds of the server. So when the player uses the item you set the players dynamic property to the Date.now(), but you will have to add the cooldown to the overall time. so Player.setDynamicProperty("cooldown", Date.now() + 1000 * cooldownInSeconds).

Once the player tries to use that item, you check using Player.getDynamicProperty("cooldown") if Player.getDynamicProperty("cooldown") < Date.now()

@native osprey

[native osprey]

This goes in main.js?

it has to go here?

[last latch]

yeah

[marble sigil]

@minecraft/server-gametest still experimental?

[round bone]

https://wiki.bedrock.dev/items/item-components#cooldown

[round bone]

Overcomplicated, just use native component and operate around it

[round bone]

Yes

[marble sigil]

Bruh.

I’m building something very cool, that many players wanted but other add-ons couldn’t give. 👀

[alpine ibex]

And what is it?

[shell sigil]

jk

How do I fix this why I can only put dirt it should be equipment's only

[native osprey]

Okay i added the component to my item but i still see no cooldown, perhaps i need to link it to the script in main.js?

[round bone]

What do you mean by link?

[native osprey]

like do i have to add the runCommand script to the cooldown category?

[round bone]

You mean, to trigger cooldown?

[native osprey]

that, yeah

[round bone]

Uhh, this is incorrect

"minecraft:cooldown": {
    "category": "magic:elemental_staff_cooldown",
    "type": "use",
    "duration": 0.8
}

Category is a namespace of this, "use" that you've provided should be in "type" field. Just copy it and should work fine. I think you just need to check if cooldown is over 0

[round bone]

So in this script, you just have to check for cooldown:

import { world, Player } from "@mincraft/server"

world.afterEvents.itemUse.subscribe(({ source, itemStack }) => {
    if (source instanceof Player) {
        switch (itemStack.typeId) {
            case "magic:elemental_staff":
                if (source.getItemCooldown("magic:elemental_staff_cooldown") > 0) return
                // This code will only trigger, if cooldown has passed.
                source.runCommand(`say test!`)
                return
        }
    }
})

[native osprey]

im trying but now it doesnt let me use the item at all

it doesnt show errors or anything, it just doesnt run the command

[round bone]

Can you show me your current code?

Try coping and pasting again

[native osprey]

@round bone i exposed the database i think its all secure

uses jwt keys for read perms and a seperate one for read AND write https://panel.g07hn.com/players

hopefully no one can access or write to the data

[last latch]

Someone said it didn’t work properly so 🤷‍♂️

[native osprey]

So... Any idea?

[last latch]

Can you log the outcome of "getItemCooldown()"?

[native osprey]

The black message it shows?

[last latch]

i guess ye

[distant tulip]

anyone have a working A* algorithm? i had problems with the one from nox7

[north rapids]

Is there a way to call a scriptEvent without using commands? I've never used it before.

[round bone]

Other people even upvote my solution, just claim that your is overcomplicated for no reason

[round bone]

👏

Do you refresh these keys?

You don't really have to tbh, if you have a constant key that you'll change every single few weeks, it should be already fine

[fallow minnow]

i mean i can

its super simple but eh

if anyone somehow gets access they will need to find both jwt so

[round bone]

It's pretty easy to secure a server, so don't really mind about these things

[last latch]

?

what

[devout sandal]

for dimension.playSound(sound, location, {pitch: }), what is the default pitch, and what are the ranges, i cant find info on it anywhere..

[marble sigil]

You can omit them.
Default pitch is 1.
Default volume also 1.
Ranges are defined in sound_definitions.json

[devout sandal]

Ik if i am going for default I can omit, but i am having 4-6 noises play that are the same sound and i want each successive noise to be slightly more pitched up than the last.

[marble sigil]

O, I see.

[snow knoll]

You need the command
What would that even be good for

[round bone]

System.sendScriptEvent

https://learn.microsoft.com/en-us/minecraft/creator/scriptapi/minecraft/server/system?view=minecraft-bedrock-experimental#sendscriptevent

[round bone]

Nope, you can simply use a method from System class :p

[snow knoll]

Damn
News to me

[round bone]

It has been there for a while IIRC

[marble sigil]

But you can execute the command also.

In simple words, it’s possible to call command if you can call that method.

[worldly heath]

how lightweight is dynamic properties?

is it a bad idea to use getdynamicproperty() every tick

[woven loom]

ye

[marble sigil]

Yep, you should use a Map or Object (with Object.create(null) for dictionaries)

[worldly heath]

alr thanks

is it same case for scoreboards if i use getscore

[round bone]

Yes, try to reduce API calls as much as you can

[round bone]

It depends on the usage as well, using native methods is always better

[summer cloud]

How do i create my own custom unicode charecter

[distant tulip]

@strange marsh if you have time to look into this

[north rapids]

I want to use it to transmit data between scripts from different add-ons.

[north rapids]

Ty

[marble sigil]

Yes, but not a necessity to chase microseconds.
I just assumed if someone can’t call a command, then they cannot call sendScriptEvent

[round bone]

Native method has a higher range of usage

Also, it's always better to use native methods

[marble sigil]

Wydm "higher range"
Y mean more customisablity?

[marble sigil]

Only if it’s not taking you 2 hours or not requiring you to make a one-liner huge

[round bone]

If you'd like to call e.g. /scriptevent via runCommand without binding it to any entity, block etc., you would have to get a dimension first

[round bone]

Just wrap it around a class/function to re-use it later

There are some samples on #1067535712372654091 also

[fallow minnow]

does anyone know why bds is corrupting my worlds?

i made a void world and applied it to the server but when i join its just a default vanilla worldf

every single time i put a world on it

[round bone]

Can you tell me step-by-step how do you apply your world?

[fallow minnow]

i got it working

i had to zip then download it

[round bone]

Nice

[fallow minnow]

but now my endstone is messing up

it says its running on endstone yet the SDK doesnt wanna work

[round bone]

What do you mean by SDK? Endstone API plugin?

[fallow minnow]

no they have a script api sdk so i dont have to use python or c plugins

it just builds on top of bds

u can grab xuid, ip, ping, set boss bars and other things

[round bone]

This error is probably related only to Endstone rather than pure BDS

[fallow minnow]

yeah for sure

but its running endstone so like idk

[round bone]

You also can use regular BDS and have these properties inside your script

[fallow minnow]

wdym??

[round bone]

XUID you can read out of console, bossbars are possible via JSON UI, for rest of props you can use a proxy

[fallow minnow]

boss bars are possible via json ui yes but endstone has client sided ones

which i need for displaying stats

[last latch]

Show me the error

Is it one related to permissions on windows?

[cyan basin]

This error is so annoying

All I get is this error when trying to use the ScriptSDK on Endstone

[last latch]

Yea had this issue too

Someone said use docker but I installed Linux instead so yeah

I wish endstone wouldn’t be that dead support-wise

[fallow minnow]

no it was just not using my sdk

but i found out what was wrong

[cyan basin]

Yeah I used docker and for whatever reason it killed my internet connection on my computer

[fallow minnow]

i didnt have the whl plugin in my plugins folder

but it all works now

[cyan basin]

Not sure how it corelates to that but somehow it was slowing my speed down so much it made my PC unuseable until I uninstalled it

[last latch]

All Good. Seen that conv in endstone server a minute ago lol

[last latch]

Weird. Maybe could you try a VM?

It would be harder to develop using it but still better than nothing

[haughty kernel]

Is it possible for me to make an entity catch fire via the API?

Yeah, I wouldn't recommend it lol

[unique apex]

hey does anyone mess with simulated players? i cant get mainhand and offhand to update correctly (or more accurately, automatically) as even if its inventory is full nothing appears in the mainhand unless I reload the world.

[warm mason]

no

[cyan basin]

why not? it's all just resource packs right.. forms can read from any resource pack lol

[distant tulip]

it is like this, you can use any picture from my pc, just give me the full relative path and i will handle it

you can't know the texture path from script api

[cyan basin]

what?

if they meant pulling the texture from an item then sure you can't do that but just putting a texture from any resource pack is fine

[distant tulip]

yes that what he asked for

[cyan basin]

🤷‍♂️

[distant tulip]

i guess you could use json ui

[cyan basin]

oh actually true.. if you use aux ids lol

[latent wing]

Does anyone know why the subscribe property isn't being read when I use this line? I want to display ranks and such when a player sends a message.

[buoyant canopy]

I am checking before i commit into an idea i end up scrapping, can we get and set mob equipment? like the weapon a zombie is holding?

[wary edge]

Via runCommand.

[buoyant canopy]

I kinda need to get the item type and durability of the item, change the durability and return it to the mob.

so commands won't really work for me

[wary edge]

Then no.

[buoyant canopy]

most likely a no, but is it possible to force a mob to swing their arms? not by playing a custom swing animation

like the java swing command

[sharp elbow]

There is the hasitem selector argument. It can query item ID, slot, amount, and data value. Though it doesn't sound like it is very useful in your case

[buoyant canopy]

i know, while data is the durability of the tool, the item will still lose its enchantments if i use that

[sharp elbow]

Aye, enchantments on non-player equipment seems to be a rather big hole in Bedrock tech right now

[buoyant canopy]

it's a simple class inheritance that could fix the problem but they still didn't do it

[buoyant canopy]

What happened to dimension.getGeneratedStructures()?

[thorn flicker]

its in beta.

[buoyant canopy]

I am damn sure i read in a changelog that it was released

nope

last time it was mentioned is in .120 experimental section

sadly that part of the development was lost, if you are working on something similar, maybe shoot me a dm and i will see if i can help or point out how i did some things

[fallow minnow]

are the inventory events in here yet?

or something where i can get the item they pickup

[distant tulip]

Inventory change? Yes

            data.itemStack.setLore([`§f`, `\uE141 §r§v${price} §7each`]);
        }
    }
})``` i just get cannot read property typeId of undefined

[subtle cove]

?.typeId

[fallow minnow]

yeah but why is it erroring when i pick up cobblestone

or any item

[subtle cove]

beforeItemStack can be undefined

and when dropping an item, itemStack can be undefined

[fallow minnow]

okay that fixes the error

but

when i drop it doesnt log anything

i dont get a "picked up"

[subtle cove]

the top guard clause should different then

[drowsy scaffold]

How does the volume property work for entityQueryOptions? I'm trying to use it to get entities to remove, but it returns a empty array

const removedEntities = overworld.getEntities({volume:cosmetics.from, location:cosmetics.to, excludeTypes:["minecraft:player"]})

[subtle cove]

its like dx

[drowsy scaffold]

ah I see I see

thank you sir

[floral copper]

guys can anyone briefly explain how custom components work?

[subtle cove]

from my perspective, it's just like a frozen json object where u can only read it's contents (string, number, boolean)

which is defined in .json

[warm mason]

U have to register a component in a script, like this:
⁨⁨```js
system.beforeEvents.startup.subscribe(startup => {
startup.blockComponentRegistry.registerCustomComponent('my:custom_block_component', {
onPlayerBreak: ((data, params) => {
data.player.sendMessage('You broke ' + data.block.typeId + ' with params: ' + JSON.stringify(params.params));
})
});
});

then, when you're making a block, in it's components u need to add your component, for example:
⁨⁨```json
"components": {
  "my:custom_block_component": {
    "param1": 1,
    "param2": [1, 2, 3]
  }
}
```⁩⁩

then u can add some events in component (in script) and if a block has this component, it will trigger the events. All events u can find here: https://learn.microsoft.com/en-us/minecraft/creator/scriptapi/minecraft/server/blockcustomcomponent?view=minecraft-bedrock-experimental

And u also can use the params, that u specified in json

[hoary sun]

truly a custom component

Why does it even exist

[wary edge]

Performance reasons.

As always.

[zinc breach]

is there a function or something that lets you cause explosions and control their power

and like when are we getting an event that listens for crafting bro 💔

YESSS TY

[lucid dust]

np

[deep arrow]

lol

[last latch]

damn, using blocks instead of JSON UI to display UI is 🔥

[deep arrow]

i orginally planned on using some ui for it when i made it, but i cant do json ui so i was cooked 😭

also its not using script api

[knotty plaza]

The json ui thing I can accept, but doing it without scripting is just psychopathic

[deep arrow]

Script api is too slow for the cpu emulation

[warm mason]

but how does it work then?

[knotty plaza]

Sounds fair

[deep arrow]

Im using a custom server software

SerenityJS

[warm mason]

oh

[knotty plaza]

Say that from the start, I was worried for your mental health

[deep arrow]

When I tried on script api first it got about 1.7% the normal speed of a gameboy

[deep arrow]

It was in script api first but was too slow and i put i on serenity which runs node not quickjs, and it ran 100x better

So my sanity is still gone

But it's functional

[last latch]

is it out of beta?

[deep arrow]

Wym?

[last latch]

if serenity is out of beta

[deep arrow]

Oh

Umm idk tbh

I didnt know there was a "beta"

Its constantly updating but has beta releases like script api does, stuff that is in testing before stable

[fresh comet]

I just need some help with this formula, I want to increase the view distance by atleast 5, afterany tries I still dont know how.
If possible, how do I make it detect the nearest block in range instead of bypassing it

export function blockFromView(player,prop){
  const lastPlace = player.getDynamicProperty(prop)
  
  if(!lastPlace) return;
  const viewDir = player.getViewDirection()
  const headLoc = player.getHeadLocation()
  const facing = {
    x: (headLoc.x + viewDir.x),
    y: (headLoc.y + viewDir.y) - 1,
    z: (headLoc.z + viewDir.z)
  }
  return player.dimension.getBlock(facing)
}

[snow knoll]

You could just use getBlockFromViewDirection could you not?

[fresh comet]

That will not detect air tho

But I've tried to do both functions that if getBlockFromViewDirection failed, it uses getViewDirection instead

[stray spoke]

Yo

What script do I make

[buoyant canopy]

in pistonActivate afterEvent, when does piston.isMoving return false?

[buoyant canopy]

2 game ticks later, figured it out

[last latch]

Script API

[marble sigil]

I have a duration parameter in my custom command, should I have it in ticks or in seconds, and should I specify the format in name like "Duration in ticks"?

[distant tulip]

Depends

[thorn flicker]

ticks probably.

[lucid dust]

what's the best way to check if a slot in the player's inventory is empty? my script keeps crashing because it "cant read property 'typeId' of undefined" when the slot is empty :(

[thorn flicker]

check if the item is undefined in the slot.

[lucid dust]

is this correct?

if (item.typeId !== undefined) {
    return (item.typeId);
}

[thorn flicker]

just do
if (item)

[lucid dust]

tysm, it works now :D

[thorn flicker]

idk how it was crashing though

[lucid dust]

[Scripting][error]-TypeError: cannot read property 'typeId' of undefined at itemMainhand (main.js:58)
at jjkTick (main.js:18)

this was the crash log

[thorn flicker]

well, thats not a crash

[lucid dust]

the entire script stopped working after though?

[thorn flicker]

I thought you meant crashing your game/world.

[subtle cove]

what should it return if undefined?

[lucid dust]

return("");

[subtle cove]

⁨return item?.typeId ?? ""⁩

[thorn flicker]

compact

[subtle cove]

well, that's how itemStacks has been anyway

[lucid dust]

nice, ty

[round bone]

Most of commands are using ticks, so I'd stick with ticks

[nova flame]

in addition?'

[buoyant canopy]

why is entity.getRotation().y always 74.51033...

i want to get the block the entity is looking at but the result of getBlockFromViewDirection is incorrect
so i am trying to calculate it myself but rotation is also incorrect

entity.getRotation().y seems to return the rotation the entity spawned facing

[jagged gazelle]

Use getBlockFromRay and add 0.1 in y-axis

[buoyant canopy]

tried that it's bugged

[jagged gazelle]

define bugged

[buoyant canopy]

this is the only solution that worked for me

[buoyant canopy]

the raycast of the entity only updates when i hit it

[jagged gazelle]

it returns undefined if there's no block.

I guess u already knew that??

[buoyant canopy]

i know, for example if i hit the entity and place a block if from of it it detects it, but when the entity turns around it still detects it until i hit it again

[jagged gazelle]

I dunno then, I never had a problem with ray casting

[jagged gazelle]

are u using view direction or rotation?

[buoyant canopy]

for players maybe but for entities it's bugged

[jagged gazelle]

Don't need to send it twice bruh

[buoyant canopy]

meant to send this

[buoyant canopy]

this returns the same thing as getBlockFromViewDirection

[jagged gazelle]

It's the direction of the entity

Not the ray casting itself...

[buoyant canopy]

wdym?

[jagged gazelle]

the ray will just create a ray based on params you put

[buoyant canopy]

ok...

[jagged gazelle]

obviously but what I meant is the value you put itself

try to create a particle ray using the direction of the zombie facing

[buoyant canopy]

what value do i put? getRotation is bugged also

[jagged gazelle]

here...

[buoyant canopy]

how do i get the direction?

[jagged gazelle]

getViewDirection

[jagged gazelle]

the one ur using here

[buoyant canopy]

i already know the result but i am trying it anyway

[jagged gazelle]

yeh, I just want to know if the direction is actually correct

[buoyant canopy]

it's spawning in the direction the entiry spawned facing

[jagged gazelle]

maybe when an entity turns the view variable you used isn't updated

I can't think of anything to why wouldn't ray casting work properly unless the params put is broken

[buoyant canopy]

this is getting the entity every 18 ticks

even relogging doesn't change the view direction, it's definitely bugged

commands it is

[jagged gazelle]

then it's the getViewDirection and getRotation not the blockRay

[round bone]

Send codeblocks instead screenshots, it helps a lot for helpers

[jagged gazelle]

oh btw, use ruInterval and keep checking the view direction value

if it's actually not changing if they turn, then that's the problem but if it does, then it's how you set it up is the problem

[buoyant canopy]

it's more difficult for me, i use discord on mobile and vscode is on my laptop, i am used to sending screenshots over a usb cable but sending text is more difficult

i have discord on laptop but i don't launch it on startup to save battery

[buoyant canopy]

Interestingly x and z are changing when the entity turns but only the value and not the direction, y is not affected which suggests that it's internally using getRoation().x (vertical) and getRoation().y (horizonal) because the vertical rotation works perfectly there also but the horizontal isn't

[sage sparrow]

hi there! have mojang made any change to the item consumption after cooldown ends? something is happening to my when I use a item that has cooldown it is being removed when the cooldown ends

[nova flame]

legendary bio

[snow knoll]

A script to make me backflip (irl pls)

[buoyant canopy]

Never Mind even this isn't working!

how can a man get which block a mob is looking at???

[warm mason]

what type of entity are u using?

[buoyant canopy]

zombie villager
but it's not specific to it, all the entities that i have tried also suffer from this bug

[warm mason]

weird

[buoyant canopy]

except player

[warm mason]

what version do u use?

I mean, API version

[buoyant canopy]

2.4.0

stable

[warm mason]

maybe try 2.5.0?

or wait

it's preview only..

[buoyant canopy]

it wouldn't matter because even the command using ^ ^ ^ doesn't work

what is preview only?

[warm mason]

2.5.0

or no?

[buoyant canopy]

yeah

[warm mason]

have u tried creating new world?

[buoyant canopy]

in a new world, i ran the command to spawn a particle at ^^^1

[warm mason]

😵

wtf

[buoyant canopy]

the x and z direction only update when the entity spawns, moves or gets hurt, but the y direction updates immediately when they move thier head

i am wondering if molang queries would work

[pearl wave]

Hello! Do I need to install npm to run script api inside of minecraft? It's throwing an error of not finding "@minecraft/server"

[warm mason]

u don't need to use npm, it's just to see types, when you're coding.

and show manifest.json

there should be a dependency with server module

Like this

[pearl wave]

This is what I have

And this is the error

[nova flame]

@pearl waveshow full manifest

[warm mason]

hmmm

[fallow minnow]

is it possible to give myself a spawner with data already in it without using structures

like a cow spawner

[nova flame]

wtf is that

[nova flame]

nope

[warm mason]

and where is the dependency?

[fallow minnow]

actually i might know a way

[nova flame]

getComponent doesnt save the mob

what am i saying

[fallow minnow]

can i set blocks with certain data?

[nova flame]

u should know this

noob

[warm mason]

depends on the data

[pearl wave]

Ahh, thanks for the help! I didn't notice I had the wrong folder open in vscode... Thanks alot!

[fallow minnow]

i just want to set block a spawner with a mob already in it

[warm mason]

then no

use structures

[fallow minnow]

ughhhhh

structures for each spawner

[nova flame]

@fallow minnowwhat u making now

[fallow minnow]

and i dont wanna do custom spawners

well the only reason is performance

[warm mason]

why do u need so many spawners?

[fallow minnow]

because they are for different mobs

[warm mason]

I know, but what is your goal?

[buoyant canopy]

if only they give us nbt...

[fallow minnow]

what do you mean??

[warm mason]

I mean why do u need a spawner for every mob?

[fallow minnow]

my goal was to get mob spawners with data already on them without using structures

[warm mason]

.

[buoyant canopy]

even molang queries didn't work 😭

i am done. it's just impossible

[distant tulip]

what are you truing to do @buoyant canopy

[buoyant canopy]

get the block a zombie villager is looking at

[distant tulip]

Get block from view don't work?

[fallow minnow]

well the mob spawner doesnt just spawn every mob.. so i need spawners for each mob

[weary merlin]

You can make a system run for that with some checks when you place down a spawner set a dynamic property for it

I kinda did something similar

[fallow minnow]

ehhh yeah im trying to steer away from that

i was thinking of like

giving them a spawner with invisible lore on it ( not stackable ) which determines the type, then i just have structures that load when i place the block to replace it with the correct type

[buoyant canopy]

it doesn't, neither is getViewDirection, getRotation, commands, nor molang

[north rapids]

Is there any way to detect which face a block has been mined on?

[weary merlin]

oh yea thats smart. You can also add a tag or something to spawners in itself

[jagged gazelle]

zombie's view direction is broky-broky

[fervent topaz]

anyone know how to register new js files

mid game

[marble sigil]

Unfortunately, it’s not possible.
However, you can save a js file and load it dynamically using import() function

[fervent topaz]

no i mean when i import it

it says my file doesnt exist

[fallow minnow]

Can’t mid game

[marble sigil]

It’s a ES standard. It shall be possible.

[deep arrow]

Do u mean cant..?

[alpine ibex]

Hello May I ask a Question here but erm can you Use Get Component for Potion effects or some way? In beta or stable

Nvm

[thorn flicker]

there's a potion class

[marble sigil]

Shall = must. Think will + must.
My statement is that “dynamic imports” are a ECMAScript standard, so they must be possible in the game.

[granite cape]

hi

[weary merlin]

hey

[fallow minnow]

can i add xp to someone without summoning it and using run command

[weary merlin]

Nope they have to be in game

[weary merlin]

You could make a dynamic property that stores it and give it to them when they join

[wary edge]

https://stirante.com/script/server/2.4.0/classes/Player.html#addlevels

[weary merlin]

The player has to be online for that or it returns an error prob like not a function of addLevevels of undefined

[wary edge]

OP never clarified the player has to be offline.

[weary merlin]

Quick question, is there any tool to help with development? I want my BP and RP to be in the same file and export it to the right folders

[weary merlin]

Hmmm i will definitely look into that

[fallow minnow]

huh

[wary edge]

Are you using 2.4.0? Are there any other NPM types added?

[fallow minnow]

im using beta api

2.5 beta

is that why

[wary edge]

It shouldn't. Do you have any other NPM types installed?

[fallow minnow]

nope just these

[wary edge]

Is there any conflicts? I know there are times where installing server-ui meant the server npm types got outdated.

[fallow minnow]

i mean i can try to reinstall the types

or ill just try server

[wary edge]

#1067535608660107284 message

#1067535608660107284 message

Yeah I was right.

[fallow minnow]

soo do i just uninstall all node modules

{
  "dependencies": {
    "@minecraft/server": "^2.5.0-beta.1.21.132-stable",
    "@minecraft/server-admin": "^1.0.0-beta.1.21.131-stable",
    "@minecraft/server-net": "^1.0.0-beta.1.21.131-stable",
    "@minecraft/server-ui": "^2.1.0-beta.1.21.131-stable"
  },
  "overrides": {
    "@minecraft/server": "2.5.0-beta.1.21.132-stable"
  }
}
``` i uninstalled server and added ovverride then installed it back and i still dont get the correct things

i deleted my node modules now all types are fucked

after re installing

yeah im reverting back to my other node modules, i dont need addExp that bad

not until they fix their shit node modules

[wary edge]

I mean, you can always just use it without the types.

[fallow minnow]

true actualy

[weary merlin]

Or add it directly to the Player class thats what I do when I know it is a thing and not showing

[wary edge]

Summon creeper -> trigger the event to apply the component. You can check the files for the exact event.

[nova flame]

?

WHAT

[steep hamlet]

yall think ⁨playerInventoryItemChange⁩ is supposed to trigger everytime on ⁨/reload⁩ or does it make sense to?
for my script its usefull doing that but if its not intended and it could be "fixed" one day id rather change it now

[wary edge]

I can't recall, but does it trigger on worldLoad?

[sharp elbow]

Last I recall it did. And it triggers once for every item in the inventory IIRC

[steep hamlet]

it triggers it 8 times on worldLoad

it doesnt trigger for reload though mb

[weary merlin]

I'm guessing when the player loads or the world loads into the world, the item in that slot is changed or added from previously stored data

but i could be wrong

[covert goblet]

I have a lot of dynamic properties being read and written for a stats addon, does anybody know of any resources that could point me towards better efficiency?? Ive read that using a map to cache the data and writing it to the property at a later date is better??

[median radish]

Use scoreboards? That's what they are made for after all. If it's about stats anyway

Also sure, map will be more efficient if you save stuff in a smart way (risk loosing data on server shutdown or crash)

[warm mason]

dps are more efficient I think

[covert goblet]

Can you read from a scoreboard with scripts?

[inland merlin]

Does the damage cancel stop players from destroying armor stands?

[valid ice]

Yes; world has a scoreboard property that lets you grab info on them

[round bone]

https://learn.microsoft.com/en-us/minecraft/creator/scriptapi/minecraft/server/scoreboard?view=minecraft-bedrock-stable

You can access this via:

import { world } from "@minecraft/server"

// And all methods/props etc. will be there
world.scoreboard

[nova flame]

const form = new ModalFormData()
        .title("Add Bounty")
        .label(`§fCoins: §e$${getScore(player, "Coins")}`)
        .dropdown(
            "Select player to add bounty on:",
            allPlayers.map((p) => p.name),
        )
        .textField("Enter bounty amount:", "e.g. 100");

    form.show(player).then((res) => {
        if (res.canceled) return;

        console.warn(parseInt(res.formValues[1]));```

im pretty sure this used to work fine

idk whats wrong

[warm mason]

the API counts .label or .header as element, so the indexes of following elements are shifted

[nova flame]

ohh ok

[warm mason]

well, u need to get res.formValues[2] instead of res.formValues[1]

[nova flame]

is this a new thing?

[warm mason]

this is because u use .label

[nova flame]

ah ok

[warm mason]

in this case u can use .body

[wicked girder]

Anyone know why this specific new Date() doesnt wanna work? If I put anything inside it (ive tried nothing, any kit value, any number), it crashes the world. but removing it works fine.

[marble sigil]

I have a custom command, but it uses logic in system.run using ModalFormData and it can’t return a CommandStatus instantly. I get an error in console.
It doesn't mess with functionality, but when I want to error, it doesn't let me.

Shall I use await somehow?

[buoyant canopy]

how to check if a string resolves to a block id?

preferably without commands or try catch

[deep quiver]

store a map with all valid block ids

[buoyant canopy]

surely there is a better way

[wicked girder]

I found the issue, turns out the return message for commands are limited to 512 characters

[warm mason]

if (BlockTypes.get(id) != undefined)

[cobalt hollow]

for dyanmic properties is it 8MB total across every DP in the world including item DP's? Or is it only ones saved to the world.

[distant tulip]

who told you that there is a 8mb limit

[cobalt hollow]

I was told that ages ago ive never really fact checked it, is that not the limit?

by ages ago i mean like 2 years ish ago

its just always been in my mind

[distant tulip]

there is no limit afaik
unless you hit the key limit
and that is kinda imposible

[cobalt hollow]

key limit is 32k im guessing

[distant tulip]

there is a warning when writing stuff to fast, bu that is it

[cobalt hollow]

oh weird, im not sure where i got that 8mb max from its just always been in the back of my mind

[distant tulip]

you get a 10mb warning iirc
10mb was saved last minute or something like this

[distant tulip]

yes and no
you will need to look into how many different key you can make out of 32k
it is not just 32k key

[cobalt hollow]

ohh gotcha, im just saving player data, so each player will have their own DP with their json Data, and i have alot of other databases so just wanted to make sure, i dont think a whole 10mb will ever be saved in the span of a minute though

[distant tulip]

you shouldn't worry about it
i had a project where i saved more than 1 dp per tick for 20 minute with no problem

[cobalt hollow]

gotcha, thanks

[distant tulip]

just keep performance in mind

[cold grove]

Hii

I was reading the v2 api changes to update my scripts and optimize them, i havent tested anything yet, now i can run block related operations during worldLoad right?
During v1 i used to use ``fillBlocks()` after playerSpawn was fired

[wary edge]

Chunks still need to be loaded.

[cold grove]

I see, what about preloaded ticking areas?

[wary edge]

I have not messed with those so I have no idea.

[fallow minnow]

how can i get the players view direction in 90 degree intervals

[knotty plaza]

What does that even mean?

[fallow minnow]

like normalize the view direction into 90 degrees

like north is 0, east is 90, south is 180 etc

[knotty plaza]

I see

[shy leaf]

-180 to 180, or 0 to 360?

[knotty plaza]

I didn't understand what you meant by interval in degrees

Just use player.getRotation().y

[fallow minnow]

because i want 90 degree points instead of precise rotation

[fallow minnow]

ummmm 0 to 360

[shy leaf]

oh wait i see your question now

[knotty plaza]

So the closest cardinal point?

[shy leaf]

my memory is foggy so i dont know if .getRotation() does 0 to 360 or not

gotta test that out

(not me though)

[knotty plaza]

I think it goes from -180 to 180

[fallow minnow]

ohh wait yeah i meant rotation not view direction oops

[knotty plaza]

So again, let's say you have 80, you want it to be round to 90, or 15 to 0

Is that correct?

[fallow minnow]

but yeah basically i have a particle that i can rotate via variables and im just trying to rotate it 90 degrees based on where they were looking towards

like itll always rotate correctly facing them

instead of being in a static state of 1 rotation

[knotty plaza]

But there already is a look_at_xyz property for particles

I think that's what its called

[tidal wasp]

https://docs.google.com/document/d/194ZkcVj-MKT5Wb7f7_36uBJu8xP3Urw8IQkAAbUVsHQ/edit?usp=sharing

[fallow minnow]

yes ik but im going for something else

[tidal wasp]

something ive been thinking about recently

[knotty plaza]

You want the particle to only align with the owner's rotation?

[fallow minnow]

a lock icon appears on the block telling the player they cant break it but currently it has a set rotation, but if i go to another side it is still facing that wrong direction

like if i break it from that side it should face me

[knotty plaza]

I see

[fallow minnow]

so i need to get the rotation or whatever it is

[knotty plaza]

Wait me a minute

[fallow minnow]

i already have the particle all set up for rotations but i just need the script side of it

idk what to use

[tidal wasp]

and here is about the best place to put it

wrong reply but it frankly doesnt matter

[shy leaf]

theres something you might be interseted in

give me a second

[tidal wasp]

Who?

[shy leaf]

go7hn

[tidal wasp]

Oh

[fallow minnow]

https://tenor.com/view/dexter-james-doakes-erik-king-stare-staring-gif-1343162792415382650

at first i was going to make a fake block particle but

i got it down

and its just

too much

it would be like a locked outline thing so im just doing this

[shy leaf]

ok so instead of getting player's view direction, we can instead go by getting which direction of the block the player is at

[fallow minnow]

like the face?

[shy leaf]

close enough

[knotty plaza]

I think this should work

function snapYaw(yaw) {
  yaw = ((yaw + 180) % 360 + 360) % 360 - 180;
  const cardinals = [-180, -90, 0, 90, 180];

  let closest = cardinals[0];
  let sDiff = Math.abs(yaw - closest);

  for (const angle of cardinals) {
    const diff = Math.abs(yaw - angle);
    if (diff < sDiff) {
      sDiff = diff;
      closest = angle;
    }
  }
  return closest === -180 ? 180 : closest;
}

[shy leaf]

yeah uh thats

i think its overkill for just particle rotation

[knotty plaza]

I can be simplified a lot for sure

[shy leaf]

@fallow minnow
if you subtract block's location from player's location, youll get the direction of the player from block in vector

it should be similar to block's face location from there

[knotty plaza]

Ok I reduced the lines

yaw = ((yaw + 180) % 360 + 360) % 360 - 180;
const cardinals = [-180, -90, 0, 90, 180];
const angle = cardinals.reduce((a, b) => Math.abs(yaw - b) < Math.abs(yaw - a) ? b : a);

[knotty plaza]

I don't know about particles, but I think they use yaw instead of vector?

Again, Idk anything about particles

[shy leaf]

yeah but we dont really need to get to the angles since we only need to snap it by 90'

[fallow minnow]

im just snappig by 90'

which one thing weirdly happens

it only supports 90, -90, 180, -180

[shy leaf]

yeah thats basically how most programs handle angles

[knotty plaza]

And 0

[fallow minnow]

and 0 yeah

[shy leaf]

actually

[shy leaf]

now that you mentioned this

we can just go back to .getRotation()

just gotta handle the snap part

i wish i could test it in game but i cant rn 😭

@fallow minnow

Math.trunc(yaw / 90) * 90

feed .getRotation().y in yaw and try it

[fallow minnow]

THATS IT??

[shy leaf]

i mean

you gotta try it, i cant even test in game so i cant guarantee it

[fallow minnow]

its

wait im confused

[shy leaf]

whuh

[somber cedar]

How does Jayly get what coordinates a player sees?

[shy leaf]

oh try subtracting by -90

[somber cedar]

I am too dumb for this

[shy leaf]

also this math doesnt really have margin of error or something so its gonna be odd when you slightly tilt by right

this is why i first suggested using location to get direction

also i cant help with it too much since i am absolutely horrible when it comes to math 😭

[zinc breach]

is there a way to check what type of armor trim a player has on their armor

[jagged gazelle]

Yummy

[marble sigil]

.
Throws "Native type conversion failed"
Even in chat

[summer cloud]

Im trying to add @minecraft/server-net but my servers world dosent have beta api's enabled, how can i enable it without world corruption, and creating a new world? i tried via a nbt editor and after i add gametest to experiments and set all 3 to 1, then restart the server and redownload the level.dat file its still dosent exist

[cold grove]

Update: tested it, at least in the latest BDS, it throws chunk unloaded error

[cold grove]

Check the native methods you have used, some parameter input is the wrong type

[marble sigil]

I’m returning js { status: CustomCommandStatus.Success } or js { status: 1, message: msg }

[subtle cove]

It needs all to happen in one go.
Meaning no awaition/system.run

Least u could do is return when the form is shown without awaiting

    form.show(player).then(...);
    return {status, message}

[marble sigil]

but the problem is that I have to manually validate the form, so I can't say success or fail instantly

I guess I will do sendMessage with §c?

[subtle cove]

After the form show, yeah u can sendMessage

[marble sigil]

What status does?

[subtle cove]

Just to color the cmd result, i think

Whether it's "error" or not

[marble sigil]

Then it’s... practically useless.

[shy leaf]

its mainly used for command blocks i think

[marble sigil]

Possible to cancel critical hits and make them normal?
I don’t want to integrate my 18KB i-frame disabled giant with cooldowns.

[normal spire]

When I make a mistake in the code, the entire add-on stops working. Minecraft's debugger shows the error, but since everything else stops working, the resulting errors obscure the main problem.

Is there a way to solve this?

[cold grove]

You should handle any possible error

Using Try-catch statements, defensive code and..

Or even typescript, that helps you preventing unexpected cases, and write cleaner code

does world.beforeEvents.entityHurt not exist?

if so does it require Beta API's

[wary edge]

Yes, preview beta APIs.

[noble ibex]

Is the command syntax different when you use dimension.runCommand()? This command runs fine when I run it from chat, but the syntax breaks down from the script.

execute positioned ~~~ run stopsound @a[r=50] record.lucas_bowl vs
execute positioned ${block.x} ${block.y} ${block.z} run stopsound @a[r=50] record.lucas_bowl

[plucky junco]

Hi, i want to get into scripting, and i need a up-to-date tutorial about scripting. Any chance anyone has what im looking for?

[dusky flicker]

whats with this new ddui?

and what has it to do with data driven?

cuz on the docs i didn't see anything related to it

[wary edge]

What docs are youu searching?

Look at #1468349958221729823

[dusky flicker]

microsoft one

i mean, does it relate to data driven programming, or am i confusing things?

[wary edge]

It's the new UI.

I think the docs explain it very well.

[dusky flicker]

so has nothing to do with the data driven im thinking

[wary edge]

What are you thinking?

[dusky flicker]

data driven programming, cache hits, and stuff like that

[wary edge]

Ah no, not at all.

I see your confusion now.

[dusky flicker]

i thought it'd be ui with that kind of thing in mind

well, thanks

imma checkout the docs

[marble sigil]

It's Beta API in Beta Version, so its not accessible (I stay on stable, but I'll changing my mind to previews)

[warped blaze]

damn, i need a full tutorial for the new ddui, can't even understand ts 😭

[cunning canyon]

How can I use dimension.setBlockType in an unloaded chunk?

I’m trying to use the tickingarea command before calling setBlockType but it doesn’t seem to work.

[knotty plaza]

There is a ticking area manager in the World class

It is async so you have to await it before continuing your process

[cunning canyon]

Oooh I didn’t know that, but I don’t see it in the documentation, did it get deprecated?

[knotty plaza]

What module version are you using?

[cunning canyon]

I was about to say latest (2.4.0) but I see that there’s a newer one (2.5.0) lol.

The ticking manager is in 2.7.0-beta, hmm I would need to enable the beta API in the world settings, correct?

[knotty plaza]

I didn't notice it was still in beta

In that case you can either switch to beta or wait 1-2 ticks after running the tickingarea command

[cunning canyon]

I even give the game 5 full seconds and it still ignores the setBlock function.

I’m trying to make a safeguard to run something at the original position if the player suddenly teleports or changes dimension

I think it might have to do with the game caching the chunk thinking it’s loaded and then ignoring the functions

[knotty plaza]

How are you running the command?

Maybe it's failing because of the syntax

[cunning canyon]

dimension.runCommand(`tickingarea add circle ${string(previousLocation} 2 blah`);
system.runTimeout(() => {
dimension.setBlockType(etc)
dimension.runCommand(“ticking area remove etc”)}, 20);

Sorry for the formatting I wrote it from my phone lol

The commands always return result.successCount = 1

[knotty plaza]

Is previousLocation a Vector3?

Try tickingarea add circle ${pos.x} ${pos.y} ${pos.z} 2 something true

I think string() isn't even a thing

Also check if the ticking area list is not full

The command has a limit of 10

[cunning canyon]

Yes, string is a custom function that takes a vector and returns ${v.x} ${v.y} ${v.z}

[cunning canyon]

I’m testing in an empty flat world with nothing going on

[knotty plaza]

Isn't string is a reserved word?

Also you didn't close the function

Also add "true" at the end

[cunning canyon]

Don’t pay attention to the syntax, I wrote it from memory xd

But the logic is correct, it does run without any errors but the block doesn’t get replaced

I’m 90% sure is not about the code itself but rather a Minecraft quirk

[granite cape]

console.log('Hello World')

[cunning canyon]

Here's the actual code:

console.warn("1");
const unloadedPosition = { ...previousPosition };

previousDimension.runCommand(
    `tickingarea add circle ${Vector.toString(unloadedPosition)} 2 ${TICKING_AREA_NAME} true`,
);
system.runTimeout(() => {
    console.warn(Vector.toString(unloadedPosition));

    previousDimension.setBlockType(unloadedPosition, MinecraftBlockTypes.Air);
    previousDimension.runCommand(`tickingarea remove ${TICKING_AREA_NAME}`);
    console.warn("2");
}, 20 * 5);

I hopped back to my pc to test and still doesn't work... anyways probably a Minecraft quirk, thanks for the help regardless

[knotty plaza]

That's weird, I used that method before and it worked for me

let tickPos;
let block = dimension.getBlock(current);
if (!block) {
    if (tickPos) {
        dimension.runCommand(`tickingarea remove "${tickID}"`);
        await system.waitTicks(2);
    }

    tickPos = current;
    tickID = `namespace:${system.currentTick}`;
    dimension.runCommand(`tickingarea add circle ${current.x} ${current.y} ${current.z} 2 "${tickID}" true`);

    await system.waitTicks(1);
    block = dimension.getBlock(current);
}

[cunning canyon]

hmmm weird, I'll do more testings tomorrow

thanks for the help regardless!!!

[young swan]

I unintentionally unlocked a new gameplay style XD

[woven loom]

How are u detecting key pressesw

[distant tulip]

looks like third party code

[thorn flicker]

why share it here then

[young swan]

I used websocket

WebSocket is kind of a ScriptAPI, I think.
If not, I apologize for posting this here — there doesn’t seem to be a chat specifically about WebSocket scripts.
You can do a lot of things with it, and a lot of people just ignore it XD.

[thorn flicker]

with server-net right

i kinda forgot that was a thing lol

[young swan]

server-net isn’t fun
WebSocket connects directly to the client.
It’s almost like a mod that can be used on any server
You just need to have it to use it

[fiery solar]

The tickingarea command has a few issues, but you can work around them in the meantime until the API comes out of beta.

1. The big one is that in my testing if you use the "circle" tickingarea it will keep the entities loaded, but not actually load the blocks. (This might have been fixed since then, but it was definitely true at one point).

2. After you create a ticking area it can take any amount of time to load the chunk. Usually around 5-6 ticks, but sometimes more than 10 seconds. It's best for you to wait until dimension.isChunkLoaded returns true.

3. When you remove a ticking area with the command it isn't removed right away. You need to wait until at least a tick after the chunk is done saving (when isChunkLoaded starts to return false) before you add a tickingarea with the same name back or else the add command will succeed, but the game will never actually add the tickingarea.

[dusky flicker]

so did you use the websockets api? wasnt it deprecated? i have tried using it before but due to the lack of docs i gave up

[fiery solar]

I don't think it was officially deprecated, but they have been very clear it's undocumented and unsupported and they might remove it or change how it works at any time so a lot of people don't want to invest the time to do things with it.

[young swan]

It was never well documented, apparently it’s lot used in the Education Edition.
Mojang should pay more attention to it
it’s literally client-side scripting.
It can read a ton of events, but it can only execute commands.

[young swan]

bruh

At least can make a command macro :3

[dusky flicker]

can you share the code? so i inspect it and maybe i generate some docs for it

[young swan]

There’s a PDF floating around somewhere
I saw it once, but it was on a site that wouldn’t let you download it without paying.
I made a simple one using TypeScript.

interface SendCommandWS
{
    header: {
        version: 1,
        /**
         * uuid
         */
        requestId: string,
        messagePurpose: "commandRequest",
        messageType: "commandRequest"
    },
    body: {
        /**
         * minecraft command
         */
        commandLine: string
    }
}

The upside is that the site doesn’t block screenshots

[cunning canyon]

I see…
I’ll keep trying, thanks for the info!

[wary edge]

Anyone made a system like Hytale where you can mine 1 block together to speed it up/track progress?

[wary edge]

😔 Oh, there's not swing stop.

Oh wait, Mine keeps activating swing.

[wary edge]

Can't believe I found a use for unsubcribe.

[summer cloud]

does the @minecrafter/server-net api module, have a request limit when talking to a server?

[fallow minnow]

in terms of rate limiting i dont think so, in terms of how much youre sending yes which is watch dog

if you exceed the memory limit it may crash you

but im listening for discord messages and online players through a bot and bridging it with server net every second with no issues

left the server on for hours and no issues

[summer cloud]

thats pretty much what im doing, i just have a constant connection, and i created a runTimeout where if theres no response itle close the connection to the websocket, and i was getting randomly disconnected, so just making sure it was somthing wrong with the code rather than something else

[worldly heath]

is it possible to use addEffect() with infinite duration?

[wary edge]

Unfortunately no, you'd need a higher number of use runCommand.

[worldly heath]

ah alright

thanks

[round bone]

There's also an option inside of server's configuration to manipulate how many request each add-on can send to a certain URL

[jolly citrus]

I'm using setCurrentValue for a custom damage system on my addon but with absorption hearts in play it gets weird, it seems like the hearts shown to the client do not match what the server knows

i can right click any item in my hotbar and suddenly, all my absorption hearts are back

and then i just see normal hearts suddenly lower

[midnight ridge]

guys how can i make something for exampl i want to make an ore scanner that scans the area and shows the ores behind the walls but the problem is how can i show them and make them appear behind walls??

[distant tulip]

Entities with custom materials

[fallow minnow]

anyone else notice that inventory change after event fires upon player join?

meaning the game re-gives their items upon joining

which is kinda cool

[wary edge]

Yeah.

No idea if its WAI or Bug.

[fallow minnow]

i find it quite cool, i use the pickup method thingy for assigning prices to certain items

and for them to update they just rejoin

or just re pick up the item again

[wary edge]

Are you talking about PlayerInventoryChange or EntityPickupItem that was recently introduced?

[fallow minnow]

inventory change

and you just use the item not before item

so it only runs on pickup

[distant tulip]

Make sense
The client don't hold the inventory infos

[fallow minnow]

yeah its pretty neat

it gives all your items on join

[distant tulip]

Armor too i assume

[hexed pier]

What is the Minecraft server API 1.21.130+?

[somber cedar]

2.4.0 - check https://jaylydev.github.io/scriptapi-docs/latest/modules/_minecraft_server.html

[wary edge]

Any way to get the item entity that is dropped from a block?

[weary umbra]

Yes.
world.getLootTableManager().generateLootFromBlock(block)

[wary edge]

That returns an ItemStack.

It does not return the actual entity instance.

[tidal wasp]

Does return in a OnPlayerInteract stop the player from breaking blocks?

[wary edge]

No. Use the player break block before event.

[tidal wasp]

Ok the why tf cant i break dirt

[wary edge]

Are you in adventure mode?

[tidal wasp]

No im like something stops me every time I start breaking something

I can break something if it can be instamined

Its my fucking controller 😭

Because I have x to destroy block

And for some reason the game doesnt like that

Ok so I fixed it

What happens when you dont use return at the end of something like world.beforeEvents.playerInteractWithBlock or something like that

[wary edge]

Nothing.

[lethal bramble]

functions always automatically return at the end

[marble sigil]

Will DDUI be replacing ModalFormData and etc?

Those FormData stuff

[buoyant canopy]

hopefully not anytime soon

but they will eventually

[marble sigil]

but they keep archives for these modules right?
like we still have and can use @minecraft/server 1.8.0.

[weary umbra]

Oh, try to get it with world.getDimension("overworld").getEntities({type:"minecraft:item"location:block.location, maxDistance:1})

[zinc breach]

is there a way to make a player glide without an elytra

[warm mason]

u can try applyImpulse with slow_falling effect

[wary edge]

That wont work as a player can jist drop an item.

[zinc breach]

what does applyImpulse do

any documentation on that?

[warm mason]

Gives speed to an entity in a certain direction

[weary umbra]

Hmm than no idea

[warm mason]

https://learn.microsoft.com/en-us/minecraft/creator/scriptapi/minecraft/server/entity?view=minecraft-bedrock-experimental#applyimpulse

[warm mason]

U can use before and after variations of playerBreakBlock to getEntities in beforeEvents and store them in a variable and then in afterEvent u use getEntities again and filter the list to get only new entities

[zinc breach]

alr tysm

[wary edge]

Too many edge cases such as non full blocks.

[zinc breach]

is saving items in dynamic properties reliable with itemstack

in terms of duarbility names enchants and that sort of thing

also want to know if I can save a big object in a dynamic property with all the inventory slots as keys for an item

[weary umbra]

Wait what you can change the selected slot with
player.selectedSlotIndex = 9

I didnt know that. I thought it only returns the slotIndex

[tame spear]

How can I .nameTag with translate? 😔😔😔😔

[warm mason]

I don't think u can

[distant tulip]

what does getEffects return in duration if the effect is infinite?

[supple perch]

if i had to assume

either Infinity

or undefined

or maybe it gets ignored

let me test for you rq

-1 actually

interesting

slowness had a real number, night vision had infinite

i wonder why they won't/can't add infinite to addEffect

anyway

[distant tulip]

can you set it to -1?

[supple perch]

uh

no

the bounds error will appear

i think

[jagged gazelle]

that's crazy work ngl

[distant tulip]

alright, thanks

[supple perch]

i'll test tho

[jagged gazelle]

just add the ability to set it as Infinity like...

[supple perch]

fr

[supple perch]

yup like i said

[summer cloud]

is it possible to cancel join msgs?

or atleast edit how they look if i cant cancel it

[cold grove]

Resoruce pack

[summer cloud]

yea but how?

[cold grove]

/texts/ directory, edit the .lang files

[summer cloud]

and put what?

[cold grove]

[cold grove]

https://wiki.bedrock.dev/text/text-intro

[supple perch]

nah

[cold grove]

Use the vanilla resource pack and download the file and edit it

[supple perch]

you can put invisible lines to kinda "cancel" it

[cold grove]

I dont know if theres a command to the repo

[supple perch]

but i don't recommend that

[cold grove]

No

https://github.com/ZtechNetwork/MCBVanillaResourcePack

Here

[supple perch]

fair enough

[summer cloud]

k got it
multiplayer.player.joined=%s joined the game

[worldly heath]

how do u shoot an ender pearl like projectile ?

when i use spawnEntity() and shoot() it gets stuck in unloaded chunks

but if i throw an ender pearl normally it'll land as usual

[fiery solar]

I think this behavior might be hardcoded for the ender pearl, but you can try adding the "minecraft:tick_world" component to your projectile entity though, it might work but I've never tried it for this.

[worldly heath]

i tried spawnEntity with vanilla ender pearl and it is also having the same effect, its not loading chunks while spawned with scripts but does when i throw manually

i had to edit ender pearl.json to make it spawnable idk if that broke anything

[worldly heath]

thanks I'll try , i was wondering if theres any better methodes for shooting projectiles

[nova flame]

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

const trackedItems = new Map();

const DESPAWN_TIME = 30;

system.runInterval(() => {
    for (const [entity, data] of trackedItems.entries()) {
        data.remaining -= 1;

        if (!entity.isValid) {
            trackedItems.delete(entity);
            continue;
        }

        const item = entity.getComponent("item").itemStack;
        let name = item.typeId.split(":")[1] || item.typeId;
        name = name.replace(/_/g, " ");
        name = name.replace(/\b\w/g, (char) => char.toUpperCase());

        entity.nameTag = `§f${name} §cx${item.amount}\n§e${data.remaining}s`;

        if (data.remaining <= 0) {
            entity.kill();
            trackedItems.delete(entity);
        }
    }
}, 20);

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

    trackedItems.set(entity, { remaining: DESPAWN_TIME });
    const item = entity.getComponent("item").itemStack;
    let name = item.typeId.split(":")[1] || item.typeId;

    name = name.replace(/_/g, " ");
    name = name.replace(/\b\w/g, (char) => char.toUpperCase());

    entity.nameTag = `§f${name} §cx${item.amount}\n§e${DESPAWN_TIME}s`;
});```
 ive had this system for a while and i wanted to change it to display the items "display name" instead of the split up typeId

possible?

[warm mason]

nameTags don't support rawtext, so no :(

[nova flame]

but like

no possible way at all

to get the items name?

like named in an anvil say

[warm mason]

Well, unless you transfer all the names from RP to BP, but that won't support custom items

[nova flame]

bruhhh

[zinc breach]

how do I check what type of armor trim is on an armor piece in an itemStack

[zinc breach]

is there a way to make a vanilla block a ghost block? so just make it so people can walk through it basically

[jagged gazelle]

that's.... not even a script related problem...

[jagged gazelle]

no afaik...

[zinc breach]

really? I wanted to use this in a playerPlaceBlock afterevent

what do I need to do for this to work then

[jagged gazelle]

vanilla blocks are data-driven

you can't modify them

either you give up on that idea or create a custom block having no collision that looks exactly with the block ur trying to make "ghost block"

[zinc breach]

its supposed to work for every single vanilla block so cant really do that lol

thanks anyways

[jagged gazelle]

or make a custom entity that makes the item it's holding animated to position like a block

not really perfect but almost there

[deep arrow]

If i change a block state's name, will old versions of it change or?

[warm mason]

I don't think so

[marble spruce]

Hey guys,is this well structured?

[supple perch]

nah

first move the array outside the event loop

second runCommandAsync has been removed

use runCommand instead

third, use scripting API's native scoreboard feature

[cursive fog]

in action data form can i display a variable for the body of ui instead of message?

[supple perch]

depends

is that variable a string?

if it is, then you can

[cursive fog]

ye

[supple perch]

then you can.

[cursive fog]

like .body(variable)

[supple perch]

yeah it'll work just fine

[supple perch]

fourth: i have a feeling these mcfunctions you have can be replaced by scripting API js code

but aye it ain't my business

[supple perch]

i recommend you use this wrapper instead of using the API directly: #1398563867042381905 message

but you're welcome to use the API:
https://jaylydev.github.io/scriptapi-docs/latest/classes/_minecraft_server.Scoreboard-1.html

(accessible via world.scoreboard)

[cursive fog]

do i need server ui for onscreen display component?

[supple perch]

no

just use player.onScreenDisplay.method
Exmample: player.onScreenDisplay.setActionBar('hi')

[cursive fog]

i see

[cursive fog]

is it possible to add custom textures for the player.onScreenDisplay?

[supple perch]

what do you mean?

[cursive fog]

using json ui

[supple perch]

what????

player.onScreenDisplay isn't a real ui element

do you mean the actionbar?
player.onScreenDisplay.setActionBar('actionbar lol')

or what exactly?

i wanna add a custom png using json ui on the player screen. is it possible with onscreen display?

[supple perch]

you mean a hud element on the player's screen like the attack button for example?

if that's what you mean, then idk

it's probably possible but it'll be very JSON UI heavy and will be complicated as heck

player.onScreenDisplay doesn't give us an option to render a custom hud element.

[cursive fog]

oh

[cursive fog]

do yk any way for a custom hud element to render?

[supple perch]

nah man

honestly my advice: whatever the hell you're gonna do with a custom hud is NOT worth it

[distant tulip]

onScreenDisplay is a class used to access other functions such as setTitle and setActiobar
it doesn't relate to json ui in it's own

[supple perch]

it'll probably be very complicated, glitchy and laggy asf
