Script API General

[wary edge]

It's that simple. They can store Vector3, boolean, number, string.

[vast rune]

yes but my object will not be any of those types

im storing railroad tracks for my train addon
they have 4 points(vec3) for a cubic bezier curve plus 2 OTHER connected track objects

[wary edge]

Then stringify the JSON.

[vast rune]

k

[shy leaf]

oooo

[wary edge]

JSON.stringify(obj) then retrieving it JSON.parse(string)

[vast rune]

alr ty

[vast rune]

is there an event for when the world is closed

[worn basin]

I am the 100 000 message of script api general🥳

[distant tulip]

congrats

[random flint]

Yeah, congrats for being the 124th user of claiming the 100000 message milestone.
-# It'll revert back to 99999 in a few hours

[stray spoke]

Any algorithm ideas to make gui changes detection?

[worn basin]

What?

[near siren]

Any reason why custom commands, even if they are sent to CommandPermissionLevel.Any, wont show up and cant be used on realms?

[wary edge]

Is your Custom Commands rely on player selector?

[near siren]

They do not

const changeNicknameCmd: CustomCommand = {
    name: 'retrqol:nickname',
    description: 'Change your nickname',
    permissionLevel: CommandPermissionLevel.Any,
    optionalParameters: [
        {
            name: 'name',
            type: CustomCommandParamType.String
        },
        {
            name: 'retrqol:nicknameType',
            type: CustomCommandParamType.Enum
        }
    ]
}

[wary edge]

I presume then it works in Single player?

[near siren]

Yes

[wary edge]

It might require cheats enabled?

[near siren]

Hmm maybe

Dang it, realized there is a cheatsNeeded property and it defaults to true

[stable shadow]

How do I rotate the multiblock using a script? Every time I try to rotate it, it simply breaks the block, even after setting permutation on all blocks.

block.dimension.setBlockType(loc, d.typeId);

            const placed = block.dimension.getBlock(loc);
            
            placed?.setPermutation(block.permutation.withState("minecraft:cardinal_direction", "north"));

            placed?.getParts()?.forEach(r => {
                // r.setPermutation(BlockPermutation.resolve(d.typeId, baseStates));
                r?.setPermutation(block.permutation.withState("minecraft:cardinal_direction", "north"));
            })```

[open urchin]

You need to be doing r. permutation.withState

[stable shadow]

I used

[open urchin]

Also got can remove the placed?.setPermutation at the start since getParts also returns the part you're getting the parts from

[stable shadow]

Sorry for taking so long to reply, I've already tried that too.

[wary edge]

Why are you using it via scripts in the first place?

The block traits will automatically handle it for you.

[stable shadow]

@wary edge I'm developing code that places multiple multiblocks at once, which is why I'm trying to rotate it. I don't want to use structure blocks for this.

[wary edge]

Oh, you're not using a normal multi block.

You're using a custom one?

[stable shadow]

Yes, I am using the regular one, but it has several parts.

[wary edge]

So you're using a custom implementation.

[stable shadow]

I put everything together to form a block, so I'm trying to develop something that automatically adds that.

without having to place block by block

[chilly vine]

does any1 know a workaround for the fact that increasing damage dealt using beforeEntityHurt will cause totems to just not work

since it seems if you do any more damage than normal, totems just break

nvm i figured it out yay me

[marble sigil]

Dynamic Properties vs. Tags — which is faster for storing data on Entity?

[woven loom]

go for dp

[round bone]

Always go for DP, unless you will also use tags

Tags are like booleans

[marble sigil]

understood, thanks.

[fallow rivet]

Is it possible to create a custom dimension with a single command, or does it have to be done with startup?

[lyric kestrel]

Via startup

[fallow rivet]

[viral osprey]

Is there any way to override the memory limit watchdog exception without having to dump memory regularly?

[woven loom]

Why do I need cheats enabled to use entity selectors in custom commands?

[weary umbra]

bc its a bug

you cant also use /msg command

only if have op

the same for player selector

[woven loom]

When will it be fixed?

[weary umbra]

Never I think xD because it an older bug

[woven loom]

reported or not?

[weary umbra]

I didnt but I think someone did that

not sure

[remote oyster]

If it's related to scripts then this should disable it. You can find it in server.properties for BDS. If you are referring to a Realm then there is nothing you can do about it other than reduce your memory use and/or verify you don't have one or more memory leaks from bad code.

script-watchdog-memory-limit=0

[viral osprey]

It’s just that I’m storing alot of data in memory. But I’m thinking of just dumping it, after use because it’s not exactly important data

Just wanting to know ofc if I can increase the limit of memory

Thank you u

[remote oyster]

Then that property I mentioned will disable it on BDS. Can't help with Realms other than what I suggested.

A long time ago you use to be able to disable watchdog but they disabled that on Realms because it was allowing people to not debug poorly written code and putting stress on the servers so they basically said, "No more nonsense. Fix your code or it will get shut down". Lol

[junior hill]

  player.onScreenDisplay.setTitle(
    `hp:${hp} hunger:${food}`,
    {
      stayDuration: 0,
      fadeInDuration: 0,
      fadeOutDuration: 0
    }
  );
}

i wonder if this is right to set titles correctly?

[lyric kestrel]

You should try it

[junior hill]

idk why not working atm

so im just asking

[lyric kestrel]

Is there an error?

[junior hill]

no

o lol i forgot

to activate the event with a worldafter

but idk if there one with hunger

bc i got hp done

[lyric kestrel]

Try player.getComponent("player.hunger").currentValue

[lyric kestrel]

Although, it might be better to setActionBar rather than setTitle

const food = player.getComponent("player.hunger").currentValue;
const hp = player.getComponent("health").currentValue
player.onScreenDisplay.setActionBar(
    `hp:${hp}  hunger:${food}`
)```

If you want to still do the setTitle method,

const food = player.getComponent("player.hunger").currentValue;
const hp = player.getComponent("health").currentValue
player.onScreenDisplay.setTitle(
    `hp:${hp}  hunger:${food}`,
    {
        stayDuration: 10, // If this is 0, it won't appear
        fadeInDuration: 0,
        fadeOutDuration: 0
    }
)```

[junior hill]

No

ik this is scripts

but this is right?

for the ui?

i just used my health bar code

bc that worked

[unique dragon]

someone know why blocks with custom components, even without the onPlayerInteract event, you can interact with the block?

is this a bug?

[wary edge]

That should have been fixed. What format version?

[unique dragon]

nvm, fixed

ty

[crude ferry]

myEntity.target = newTarget;
Target property of an entity is read only as it's turning out.

Any work arounds?

[shy leaf]

nope

😔

[crude ferry]

Unfortunate.

[shy leaf]

do you just

store raw data

110kb in one block is insane

[lyric kestrel]

So, this is the database currently.
The true|false sections are checking whether a layer already has something in it.

[shy leaf]

OH MY GOD

[lyric kestrel]

Yeah 🥲

It can definitely be rewritten a LOT

I just don't know how to do it 😭

I checked also, and since it's a map, the 308 or so entries doesn't do anything for scripting timing mostly

[shy leaf]

i dont know much about blocks in general, but how is DP stored in a block?

[lyric kestrel]

Well, the cap is 1KB, so uhhh

[shy leaf]

say, when you print it out as text

[lyric kestrel]

It's just the same as items I believe

[shy leaf]

yeah you could... cut down some texts

[crude ferry]

Turns out teleporting the entity with a facing [entity] argument sets that entity as the target.

[shy leaf]

https://tenor.com/view/steam-happy-steam-happy-gif-4531022007608143773

[crude ferry]

:D

[shy leaf]

peak jank

[crude ferry]

It works for my very specific use case lol.

[shy leaf]

thats a bless and a curse

[lyric kestrel]

I was thinking of a system like this;

new Map<([
    {"layer1", {/*Set a liquid type, eg gold, iron, etc. Default would be "undefined"/"empty".*/}},
    {"layer2", etc, etc
])```

Only problem is, I don't know how I would go about that

So if layer1 is undefined/"empty" then it would set it, and if it had something in it, it would go to the next one

The only problem is I don't know how to set that undefined or empty as initial

[crude ferry]

Oh wait I can just setRotation(). I just need it for head movement anyway.

[lyric kestrel]

I am currently using entity properties, but I want to get rid of that and use a block entity when they come out

[lyric kestrel]

So, I'm wanting to reduce it to way below 1kb with just 16 entries

Actually, hmm

I don't know how I'd do that as I'm using an entity currently to dynamically change which layers appear or not

[shy leaf]

@lyric kestrel have you considered cutting boolean bloats down and use 16bit integer

and not include booleans that are false

[lyric kestrel]

Idk how i'd do that 🥲

I'm currently trying out a method to cut it down to only 16 entries atm

[shy leaf]

give me a second

actually 16bit integer might not fit

i just read more and i see the pattern

[lyric kestrel]

Ok, I think I got it

[shy leaf]

instead of this monolithic thing

["foundry:zinc_ingot|true|true|true|true|true|true|true|true|true|true|true|true|false|false|false|false",
        {
            layer1: true,  layer2: true,  layer3: true,  layer4: true,  layer5: true,  layer6: true,  layer7: true,  layer8: true,
            layer9: true, layer10: true, layer11: true, layer12: true, layer13: true, layer14: false, layer15: false, layer16: false,
            materialProperty: "foundry:layer13_material", materialPropertyNumber: 9
        },
    ],

you can do this

type foundryEntry = { 
    l: number; 
    m: number; 
    n: number; 
};

  [
    "zinc_ingot|12", 
    { 
      l: 13,
      n: 13, 
      m: 9
    }
  ],

and parse the stuff from script side

this may only work if the pattern is consistent

[lyric kestrel]

Nope. Apparently it kept going to the next one and doesn't reset to the 1st layer 😔

[lyric kestrel]

Hmm

[shy leaf]

yeah i dont fully know about the code but

from what i see you can cut down a lot by simplifying it

[lyric kestrel]

Yeah, I can very much so

[shy leaf]

aaand this is my random crazy thought

  [
    "zinc_ingot|12", 
    { 
      l: 13,
      n: 13, 
      m: 9
    }
  ],

to

    "zinc_ingot.12.13.13.9",

_ _

[stray spoke]

Why not use Map instead

It supports other types than string for keys

Oh nvm

[round bone]

It's better to stringify it

[weary umbra]

Is there away to check if a mob is a boss? Like Ender dragon etc. or like custom mobs

[stray spoke]

expensive to use JSON.stringify often

[lyric kestrel]

Yeah, using Map is better

[lyric kestrel]

Ok, I think the way you did I could 100% do

Wait, duhhh why didn't I do this in the first place 😭

[lyric kestrel]

Ok, I've managed to get this working

const playerInputItemsIntoFoundry: ReadonlyMap<string, { materialNumber: number }> = new Map([
    ["minecraft:iron_ingot",       { materialNumber: 2  }],
    ["minecraft:gold_ingot",       { materialNumber: 3  }],
    ["minecraft:copper_ingot",     { materialNumber: 4  }],
    ["minecraft:diamond",          { materialNumber: 5  }],
    ["minecraft:netherite_ingot",  { materialNumber: 6  }],
    ["minecraft:obsidian",         { materialNumber: 7  }],
    ["foundry:aluminium_ingot",    { materialNumber: 8  }],
    ["foundry:zinc_ingot",         { materialNumber: 9  }],
    ["foundry:osmium_ingot",       { materialNumber: 10 }],
    ["foundry:titanium_ingot",     { materialNumber: 11 }],
    ["foundry:lead_ingot",         { materialNumber: 12 }],
    ["foundry:silver_ingot",       { materialNumber: 13 }],
    ["foundry:brass_ingot",        { materialNumber: 14 }],
    ["foundry:steel_ingot",        { materialNumber: 15 }],
    ["foundry:dragon_steel_ingot", { materialNumber: 16 }],
    ["minecraft:redstone",         { materialNumber: 17 }],
    ["foundry:palladium_ingot",    { materialNumber: 18 }],
    ["foundry:adamantium_ingot",   { materialNumber: 19 }],
]);```

And I've found out there's ReadonlyMaps

Which is amazing, as I'm bound to probably mess up and accidentally add to it in a different file somewhere 😭

[wary edge]

Cant for maps you also do as const? That might be arrays only I guess.

[lyric kestrel]

Having just the const still allows for editing through methods

[wary edge]

Not what I meant.

Const arr = [] as const

[lyric kestrel]

I have no idea

[wary edge]

I know that makes the array immutable.

[buoyant canopy]

Why does beforeEvents.entityItemPickup not work on minecarts 😭

hopper* minecarts

Fix your game Mojang

[wary edge]

File a bug report? Does it work with other mobs such as allays and whatever siphons.

[random flint]

I usually use before entityRemove for that. But even before events has weird priority issue against picking up item...

[buoyant canopy]

i don't even wanna try

players do

[stray spoke]

It can be done with just plain objects if the keys are just strings. But the Map has a has method to search directly so I think that's faster

oh nvm I misunderstood

[fallen cape]

Is there any way we can update something more than once in a tick? Overall, is there something that can be updated more than once in a tick in the whole game?

[sharp elbow]

What do you need to update faster than once a tick?

[warm mason]

not really, why do u need this?

[random flint]

Server side stuff is restricted to 1 tick synchronous operation. Only RP (Like MoLang animation) can do something under a tick since they're updated per-frame. (Though, molang queries only update per tick, but basic operation aren't)

[shut citrus]

anyone got world crashing when runing for loop

[shy leaf]

if youre using JS native loop, it wont end well (mainly crash) if theres nothing that stops it

[trail marten]

do you guys know which version did @minecraft/server version 2.0.0 were released out of beta?

[shy leaf]

around 1.21.100 it seems

[trail marten]

thank you

[rough anchor]

what manifest version do i need for beforeChat events?

[remote oyster]

[distant tulip]

just use "beta"

[junior hill]

what are exactly ```js
WeakMap

[warm mason]

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/WeakMap

[junior hill]

ok its what i thought thanks

[stray spoke]

Are all entities already loaded also in worldLoad after events to safely manage it

[frosty yoke]

what was it

[chilly vine]

when a player would pop a totem, cancel the damage and then apply damage equal to their current health with the override dmg type

[wary edge]

It also could be because entity heal takes place first? So the totem heals however many to get to the 1 hp but then hurt activates so you overrode it?

[chilly vine]

yea maybe

before hurt event has a lot of odd interactions with some things

[stray spoke]

I kinda like this one

[shut citrus]

Is that real?

[weary umbra]

Bug

[shut citrus]

[weary umbra]

lol

[fresh comet]

z index of floating item renderer just lower than the search bar panel

[cobalt hollow]

is it possible in any way at all to clear the item in the players cursor in their inventory?

[wary edge]

Use the .clear() function of thr component

https://stirante.com/script/server/2.7.0/classes/PlayerCursorInventoryComponent.html#clear

[cobalt hollow]

i just got it ty:)

[pliant breach]

i'm trying to get mob mainHand slot using script but it keep saying that it cant get the component does anyone know how to fix it

function tryEquipWeapon(entity) {

const equip =
    entity.getComponent("minecraft:equippable")
if (!equip) {
    console.warn("Missing equippable");
    return false;
}

const mainhand =
    equip.getEquipment(EquipmentSlot.Mainhand);

// Already holding weapon
if (mainhand)
    return false;

const inventory =
    entity.getComponent("minecraft:inventory")
    .container;

[stray spoke]

The error is already said, the entity doesn't have an equippable component

It usually works for Players only

[shut citrus]

how to detect an entity attack got cancelled?

[crude ferry]

Got cancelled in what way?

How does an attack get cancelled unless you're doing it yourself using EntityHurtBeforeEvent.

world.beforeEvents.entityHurt.subscribe((event) => {

    // prolly some code that cancels the event.

    if (event.cancel) {
        console.log("Damage was cancelled BEFORE it applied");
        return;
    }
});```

[empty grail]

when will they make player open container/chest using script api

[weary umbra]

event.cancel = true

[empty grail]

like pls,every other api has it

pmmp,nukkit,and ofc endstone(bds btw)

[turbid canopy]

Does anyone know how to improve at script API

I want to start learning advanced programming so I can start making custom dimensions in the near future

[alpine wigeon]

well i know how to make dimensions but not how to generate things in them

this is deffo the best update for the game EVER.

custom dimensions are gonna open even more infinite possibilities if we don't have to teleport 100K blocks away in the end

[shut citrus]

I mean the damage applied on the target unsucessul

Getting a strange bug while I scripting only

[turbid canopy]

Yup

I’m planning on working on a massive souls like space addon

I have made all the souls aspects already

Just gotta make all the space stuff

But instead of following how to’s and tutorials I wanna learn scripting as a whole so I can do my own work on my own pace

[fresh comet]

There's performance limitations tho

Creating many custom dimensions and building inside per dimension creates a lot of data

Ig, because that's how usually Minecraft bedrock is

[turbid canopy]

Yh I’ve noticed that in videos I’ve seen

Really heavy on performance

[fresh comet]

Yeah

[turbid canopy]

I haven’t seen much for myself yet but is it possible to create custom skyboxes for new dimensions or something similar

[stray spoke]

How do yall even generate an infinite structures in dimension

In summary

[sudden nest]

not sure if this is a bug, but last time i check this minecraft:tamemount component to get the player or owner still doesn't work, it still doesn't work now

[turbid canopy]

Anyone know how to get better at scripting

[crude ferry]

Not really sure what that is, never worked with JSON UI.

[crude ferry]

How are you with JS/TS?

[turbid canopy]

I know the basics

[crude ferry]

If you are good there, it's mostly making things and asking for help and knowing how to search for the right thing.

[turbid canopy]

Gimmicky things you see in how to guides

The most advanced thing I made is probably a Form

It was to select classes

It didn’t work very efficiently

[crude ferry]

Oh frontend work.

I see.

[turbid canopy]

The only thing I have made using initiative is a damage sensor system to check how much damage you have taken and run a function accordingly

[crude ferry]

Have you worked with any other language?

[turbid canopy]

Not really

Apart from JSON ofc

I have made 2 semi-functional addons using my basic knowledge

[distant tulip]

https://report.bugs.mojang.com/servicedesk/customer/portal/6/MCPE-185250

[crude ferry]

JSON is a data format lol.
Anyways about the JS part. You might wanna get a little more comfortable and proficient with it.

[turbid canopy]

Yh

I want to know what steps I can take

[crude ferry]

https://www.w3schools.com/js/

[turbid canopy]

Thank you very much

[fresh comet]

The most important actually, is you learn to understand/read docs

Then you can do the rest all by yourself

With some little help ofc

Coding in cleaner way and performance friendly is a bonus

[crude ferry]

Yeah. And you also learn more doing stuff than reading stuff.

Always do some project that is a little harder than what you can do or have done so far.

[turbid canopy]

That’s my biggest issue

[turbid canopy]

I try to push myself but I default to chunky function files that can be 300 lines long of straight variables

[fresh comet]

It's not too hard, first ofc you learn JavaScript and typescript, then you'll start to understand the script api docs to use it by yourself

[turbid canopy]

Fair enough

[stray spoke]

What are you talking bout

[lyric kestrel]

Nahhhh

I just went right into scripting

Didn't know JS beforehand 😂

Just trial and errored hahah

I did know some Python beforehand though, so kinda made it a bit easier imo for the basics

[stray spoke]

Kinda the same except I have little experience with html js first

[distant tulip]

learning the syntax is enough, you can learn as you go

[lyric kestrel]

Yeah

[stray spoke]

Yep

[untold magnet]

yao, how can i save the block state when it breaks?
my block will have like two states that will change the texture (material instances stuff), so whenever it breaks or gets picked up, the state will be the same like same textures

[crude ferry]

That explains it.

[distant tulip]

brokenBlockPermutation

[untold magnet]

can the dropped item texture change based on it?

im just trying to avoid adding another 50 blocks for the new textures,

IF thats just not possible, i can make it works, i have a small workaround

[wary edge]

No.

Youll need to make many items then.

[untold magnet]

yeah ill just use the workaround instead.

[cerulean cliff]

does the debug utilities module support rotations for boxes?

[cold grove]

yes
https://learn.microsoft.com/en-us/minecraft/creator/scriptapi/minecraft/debug-utilities/debugshape?view=minecraft-bedrock-experimental#rotation

[cerulean cliff]

nope, the property doesnt work :(

L another bug

[cold grove]

pre-release i guess

thats sad

[cerulean cliff]

dont think we'll ever see a stable version

it'll probably be the same as server-net

[woven loom]

Does Navy know about the bug where the CC with entity selector requires cheats to be enabled?

[wary edge]

There should be a bug report yes.

[shy leaf]

has anyone researched EntityHurtBeforeEvent and its quirks? i couldnt test it much on my own

[earnest meadow]

is there any reported quirks? im pretty sure they only make these kind of events stable once it is actually stable

[shy leaf]

all i know so far is that it doesnt cancel fire aspects, and it has weird behaviors for tamed wolves targeting

[shy leaf]

inconsistency with invulnerability frames is the one thats reported the most atm

so no its not stable despite being marked as stable

[cyan basin]

I mean there’s always a workaround for fire aspect like extinguishing the fire on the player on entityHurtAfterEvent or something

[shy leaf]

the damage would be already done

fire tick damage specifically

[cyan basin]

You mean to things like armor or are you saying fire tick damage to player isn't canceled?

[knotty plaza]

Just cancel it from another entityHurtBeforeEvent

[cyan basin]

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

world.beforeEvents.entityHurt.subscribe((event) => {
  const target = event.hurtEntity;
  const source = event.damageSource.damagingEntity;
  const reason = event.damageSource.cause;

  if (!(target instanceof Player) || (!(source instanceof Player) && reason !== 'fireTick')) return;

  event.cancel = true;

  system.run(() => target.isValid && target.extinguishFire(false));
});```

Just been messing around with it and this cancels just fine though it does still flash the fire on the player.

No damage is dealt though.

[wary edge]

Could you also not read the damaging entity and check the weapon for fire aspect first?

[cyan basin]

As long as you specify the damage cause it stops the damage of it.

You just then need to use the extinguishFire() function to stop them from burning.

Even then that doesn't continue to cause damage since we canceled it originally.

[wary edge]

I need to do the bug report of current value returning the health after the damage is applied.

[cyan basin]

Well that's only because currentValue can't be used in early execution and requires a system.run().

[wary edge]

That makes no sense.

[cyan basin]

Oh I guess I meant when trying to set it. Whoops!

[wary edge]

Gotcha, I meant moreso reading it!

[shy leaf]

yeah thats kinda an issue... it would also disable things like fire tick from other sources

for my use case, i could do some trickery with entityHitEntity

but i dont like doing that tbh, its janky

[cyan basin]

The script I made doesn't stop damage via flint and steel or lava if that's what you're worried about.

[shy leaf]

thats direct fire damage, no?

fire tick is when youre set on fire

[cyan basin]

But the script I made is also checking if the damage is coming from a Player.

The game seems to know when the fireTick was triggered by the source. Not sure how but it does.

[shy leaf]

does game track for fire aspect's owner? last time i checked there was no damagingEntity from damageSource

[shy leaf]

vid isnt loading

[cyan basin]

Maybe switch channels and back. It loaded fine on my end.

Or reload discord.

[shy leaf]

just did that

lemme download it

oh the download isnt downloading either

😭

[cyan basin]

Bruh 😭

[shy leaf]

"24 minutes left"

[wary edge]

LMAO

Bro.

[cyan basin]

Does this work?

[shy leaf]

yeah that ones playing

[cyan basin]

Weird..

[shy leaf]

ok so uh to answer that

theres actually two damage source

fire and fireTick

iirc

[cyan basin]

Yeah, just saw those two looking at the EntityDamageCause..

There's also lava too.

[shy leaf]

tbh this is something they definitely overlooked

they specifically fixed knockback enchantment from applying

but not that

[cyan basin]

Well this one works so that the player can't deal any kind of fire damage now which is pretty neat. ```js
import { Player, system, world } from '@minecraft/server';

world.beforeEvents.entityHurt.subscribe((event) => {
const reason = event.damageSource.cause;
const source = event.damageSource.damagingEntity;
const target = event.hurtEntity;

if (!(target instanceof Player)) return;

const fireCauses = ['fireTick', 'fire', 'lava'];

if (!(source instanceof Player) && !fireCauses.includes(reason)) return;

event.cancel = true;

system.run(() => {
if (target.isValid) {
target.extinguishFire(false);
} else return;
});
});```

Pretty cool that they track the owner that placed the fire or lava.

Nevermind, I think this somehow cancels damage either way.

Yeah nevermind, my code was just poor and was canceling the damage either way. #nojavascriptskills #cantcode

[honest spear]

Well this is well known issue you are dealing with, we just have to wait for beforeEntityHit pretty much to cancel out all the effect caused by other player

in theory you could disable all fire damage in general or something

that is what i had in mind

i may have dementia tho

its like the second time script api gaslights me

[lyric kestrel]

Yeah, sadly infinite isn't considered an int

😔

[shy leaf]

isnt infinity for mob effect duration basically a boolean (under the hood)?

whether an effect has a timer or not

how hard would it be to add an extra property inside that interface anyway

[crude ferry]

No?

[shy leaf]

...really?

[crude ferry]

Oh you said under the hood.

Thought you're saying that such a property already exists.

Also, I'm very sure it's -1 and not a boolean for infinity.

[shy leaf]

[crude ferry]

Yeah.

[golden holly]

Ohk

[granite cape]

well well well

[crude ferry]

Interesting.

[shy leaf]

is Dimension.playSound method not guaranteed to play in the same tick?

[sage portal]

Havent figured out how to specifically replicate it so that I can mark it as a bug (if someone else hasn't figured it out already) but when lowering a large amount of damage that would realistically kill the player, the game only lowers the damage instead of all of the other hit mechanics (hit sound effect, applying the knockback, invulnerability time).

[wise nova]

WIll item's clone function clone the dynamic properties?

[warm mason]

it clones everything

[golden holly]

why is It Not recommended to run command from script?

[snow knoll]

Causes more lag than using built in methods

[golden holly]

Why

Command is command how can one method cause more lag

[remote oyster]

The short version: commands are expensive because they go through a completely different pipeline than native API calls.

[snow knoll]

The long version:
It is not "one method"
It is the fact that commands in scripts cause more lag since API calls in general aren't as efficient as they could ideally be
Because if this when using a command the game has to parse through the entire command and translate it into an understandable medium, whereas a native function will just tell the game to do what it you want in the most direct format possible, therefore making your game do less and be more efficient

It's essentially the equivalent to talking to someone in their first language vs talking to them in a language they don't understand and using Google Translate to put it in their primary language

[random flint]

It's mostly just a fact that I've taken as granted now. For example, if you run setblock runCommand thousands of times, the API's equivalent Dimension.setBlock will finish it earlier...

In the first place, the overhead of the communication is the issue.

In-Game, commands may work like this:

Command Parser -> Game Engine (2 layers)

In Script, commands may work like this:

runCommand (API call) -> Command Parser -> Game Engine (3 layers)
while ScriptAPI call:
Dimension.setBlock (API call) -> Game Engine (2 layers)
-# (In a nutshell: The more layers, the more overhead. While fewer layers are more performant, thus "faster")

Is there a way to apply a rotation to the multiBlock using a script?

Every time I try to apply a rotation to the multiblock, it breaks on its own. Oh, and I'm even applying it to other parts of it.

[distant tulip]

please add more context
multiBlock and parts are both vanilla native api features

what you have is not using that

[wary edge]

Go open a post in #1067535382285135923 with your script and your block JSONs.

Because what you are doing is not multi-blocks. It's a custom system. No one can help you if you use the wrong terminology.

Why does the game lag when I shoot 80 projectiles using scripts?

[shy leaf]

dont you think 80 projectiles are a bit too much?

[shut citrus]

I tested on mc java and the game still smooth

bedrock is poor optimizing

[fresh comet]

Is it possible to use system.runJob in one loop only, instead of 3 nested loops

[snow knoll]

Base game, no optimisation mods at all?

[random flint]

Maybe don't shoot 80 of them in the same tick? Splice them into a group, 10 every tick. So it takes 8 ticks to shoot all 80 projectiles.

The actual projectile simulation shouldn't lag.

[shy leaf]

i dont know what requires 80 projectiles to be shot simultaneously

but theres def a room for optimization that may not require that much

[worldly pier]

I though it was the other way around. Bedrock was optimized to run into computers with a fraction of the processing power required to run java. The lag may be because your PC isn't giving enough ram to the game

[buoyant canopy]

which loop is better?

for (let x = -1, y = 0; x < 2; x++) for (let z = -1; z < 2; z++) {
        const target = block.offset({ x, y, z })
}

for (const o = {x: -1, y: 0}; o.x < 2; o.x++) for (o.z = -1; o.z < 2; o.z++) {
    const target = block.offset(o)
}

[crude glacier]

O(n^2) ☠️ damn

Wait you can do that in js ?

Using an object instead of a regular integer

[crude glacier]

That was in the past

Now bedrock is considered heavy

[honest spear]

wdym? JS doesnt use int

all numbers are doubles

[honest spear]

second might be more performent on JITless engines

[buoyant canopy]

it looks scary until you realize that n is 3

[buoyant canopy]

like bedrock?

[honest spear]

better to bechmark but yea it should be more performant on bedrock

[buoyant canopy]

for loops are very versatile in JavaScript, the first term runs before the loop starts, the second term runs before each iteration and exists if it evals to false, and the third term runs after each iteration.

[honest spear]

not just js

all lnags wherw for loop looks like that

c, c++, c#, java

[buoyant canopy]

well the ones that inherited the C for loops

[stray spoke]

Does system runJob only work for nested loops

[sharp elbow]

Jobs work best when operating on many small operations, not so much on a few big operations. The strength of jobs is being able to use yield to defer execution until a later tick.

That said, I have not tried using jobs on singularly expensive operations, like placing structures

[crude glacier]

i meant integers like - 1 , -2 , -3 , 0 , 3 , 2 , 1 in loops ' nobody uses pi in loops

[stray spoke]

Also is there a way to clear the item that the cursor is holding

[wary edge]

https://stirante.com/script/server/2.7.0/classes/PlayerCursorInventoryComponent.html#clear

[stray spoke]

Something like

function* singleLoop(){
  for(let i = 0; i < 20; i++){
   //Something...
    yield;
  }
}

Instead of nested

If there's a workaround for it

[thorn ocean]

Can you stringify functions? I noticed when stringifying data, it seems to struggle to properly save them, which is an issue, as I need to save them.

[buoyant canopy]

you won't use a const as a loop variable, but yeah, that will run the task in 20 ticks

[stray spoke]

mb mistype

[distant tulip]

not while using i++ at least
it does work in for of, and for in

[stray spoke]

I was wrong sorry

The error I was receiving:

[Scripting][error]-[Experiment] TypeError: Native type conversion failed. Function argument [0] expected type: Generator<void, void, void>    at <anonymous> (src/ddui.js:23)

Was just because I didn't execute the generator first, I thought the syntax meant like this

for(...){
  for(...){
    for(...){
    }
  }
}

I typed it as

system.runJob(()=> theJob())

Instead of executing it

system.runJob(theJob())

[honest spear]

yea

[slow walrus]

no it'll run it in one tick

unless there's something that will take up a whole tick in the for loop

[buoyant canopy]

assuming that the generator object is passed to system.runJob

[honest spear]

yep

[honest spear]

yea but not 20ticks

yield is something the engine consumes as much as possible every tick if there is a time left in the tick

so for busy ticks it could be like 3 yields only

on other hand for empty words with no entities and no ticking areas and stuff like that, this could run about 800x per tick

[last latch]

I still have no idea what jobs are

All my projects were so optimized I didn’t ever need to use jobs

[drowsy scaffold]

they're basically just a form of running something in sync that would've been super unperformant and splitting it across multiple ticks as needed for performance, super useful thing for actions such as filling large areas

[woven loom]

Is there a way to tell if an ItemStack is a block item?

[last latch]

what stops me from running every single thing inside a job?

[drowsy scaffold]

seed for example

[last latch]

Then, why isnt all code ran inside a job from default?

I mean, if there arent any downsides.

[woven loom]

that is what i am doing rn

[cold grove]

runJob is made for things that dont have to finish in one tick

[distant tulip]

if i am not wrong, that is the only way

[last latch]

But it seems logical that almost every code/feature shouldnt lag the server.

[woven loom]

hm, thanks tho 🙂

[cold grove]

it should not lag the server

there are things that should be instant for the game experience

also if your server is that bad it will look laggy anyway because it took more ticks to finish a task

[stray spoke]

There are some issues where the loop can't run anymore at a certain amount in an instant

that's why I have to use runJob to run it safely by queueing it by ticks

It's what I've experienced when I tried to spawnParticle at ≥ 200 positions

[last latch]

https://tenor.com/view/british-cop-screaming-screaming-sad-gif-10576833416044093400

tbf i will never use jobs anyways

[sharp elbow]

Not everything runs inside a job because jobs are built with a different purpose in mind. The scripting API assumes everything to be synchronous, and it will perform all of its operations instantly if it can—from the perspective of the server, nothing is out of order; stuff that happens in one tick stays in one tick.

Where you run into problems is when your operations take a lot of time to run. When we introduce the client into this model, we introduce at least two new different perspectives where this operation time matters: The player's experience & expectations, and the information the client sends to the server.

[last latch]

so i wasted yalls time

[sharp elbow]

(Just to complete the discussion:)
Jobs have two significant downsides over synchronous code:

1. The amount of time given to a particular job is unknowable, and it will depend on the device and the current server load, so the quantity of operations done in a job cannot be relied upon; and
2. There is no guarantee that they will complete in a finite amount of time.

(I assume 2. to be true unless the job system guarantees that every job gets at least one operation a tick before it yields again)

[buoyant canopy]

synchronous code is almost always the way to go, jobs are only good if you have a large task that might hang the engine.

[lyric kestrel]

No. I've learned that I should add Jobs to my custom dimension terrain generation script!

[stray spoke]

If you meant adding lore, there's a setLore method

You have to set the updated itemstack to the slot again to actually update in-game tho

[weary umbra]

nope you cant

setblock only has bed

What format version should I use?

"format_version" tells the Minecraft API which version of the add-on system to use for a specific file. It's sadly not as simple as matching the game version however, since some systems are not updated very frequently. You may have to use an old format version with them!

i started on vscode

[turbid canopy]

It works the same as vscode

Just gives me suggestions and stuff

[stray spoke]

Usually this error happens when it can't find the script or the script file is empty

Make sure your script root file is correct in your manifest.json

if the file is empty, then that's the reason it logs that

[turbid canopy]

Yh I fixed it. That was the reason

Ty for telling me

[viral osprey]

just use copilot if u want suggestions

[turbid canopy]

Copilot?

[viral osprey]

in vscode

[turbid canopy]

How does it work

Bc I’m planning to migrate to vscode

Bridge is kinda sucky

[viral osprey]

It's just an AI model

that reads your code as you write

and gives you auto-complete suggestions

[turbid canopy]

And I’m able to ask it questions on how to improve my code or how to do something?

[distant tulip]

worst suggestion ever

@turbid canopy Use Blockception extention and npm types for scripting
copilot can be usefull but most of the time not

[turbid canopy]

Ok thx

I installed vsc and all of the plugins needed

The ones bedrock wiki told me to get

Now I’m watching an intro video

Then I’ll migrate all of my stuff from bridge to VSC

[distant tulip]

there is just a bit of manual work compared to bridge, but you will get used to it

[turbid canopy]

Yh

This is probably the best way to learn how to code

I don’t want to be spoonfed

These guys are glazing intellisense is it any good?

[valid ice]

It's goaded

[turbid canopy]

I just ported my entire addon into VSC and it’s telling me I have a lot of errors although none of these issues were present in game

Also how do I link the addon files into Minecraft so I can use /reload

[turbid canopy]

Quick update: I sorted through each issue and all of them make sense and I have fixed them, apart from one according to vsc the component “Minecraft:input_air_controlled” doesn’t exist when it very much does so what do I do

Last time I talk about non script things in script chat

[pale terrace]

Hello! bad trapdoors rotation when placing an structure with scripting is fixed?

[cold shoal]

Is there an API for the /locate command in scripting to list the locations of some structures?

[cold grove]

Not for now

You can try check for every chunk: Dimension#getGeneratedStructures()

And TickingAreaManager

[cold shoal]

Ohh interesting

[cold grove]

I do not recommend it at all

[cold shoal]

Yeah, it may affect performance and I need it on stable but thanks!

[worn basin]

https://youtu.be/a_ycG0QN5kI

[stray spoke]

I just want to ask if there's a better way to make a performance friendly loop.

It's about looping through players every given ticks to do heavy tasks

My current setup is like this:

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

const PLAYERS = new Map();
const LEVEL_DATA = [];

// save player
world.afterEvents.playerSpawn.subscribe((data) => {
  const { player, initialSpawn } = data;

  if (!initialSpawn) return;
  PLAYERS.set(player.id, player);
});

// delete player
world.beforeEvents.playerLeave.subscribe((data) => {
  const { player } = data;

  PLAYERS.delete(player.id);
});

// start loop
world.afterEvents.worldLoad.subscribe(() => {
  for (const player of world.getAllPlayers()) {
    PLAYERS.set(player.id, player);
  }

  system.runInterval(() => {
    system.runJob(defineLevelFunctions());
  }, 5);
});

let count = 0;
function* defineLevelFunctions() {
  for (const player of PLAYERS.values()) {
    player.onScreenDisplay.setActionBar(count + "");
    count++;
    yield;
  }
}

After I tested it, it seems slow when counting

And I think it creates multiple threads every 5 ticks because of runJob

[crude ferry]

Is that your heavy task lol?

And yes that does start multiple jobs.

[stray spoke]

The counting task is just a test to see how fast it counts

[stray spoke]

alright

much more efficient if its just directly runInterval but what if there's ≥ 50 players that execute heavy tasks each given tick

Could lag

[viral osprey]

It's better than whatever blockbench he's using lmfao

[distant tulip]

what?

blockbench is a modeling tool

[crude ferry]

😭

[turbid canopy]

It was bridge lol

I moved my stuff to vsc

[crude glacier]

Guys is it possible to simulate oxidations effect in script api for other blocks than copper

Like rusting , degradation, etc..

Without affecting performance much

[sharp elbow]

Probably, yeah. Based on the Java Edition explanation: The oxidization step is a bit expensive as it scans 128 blocks, but this happens very uncommonly (once on a random tick, and with a 64/1125 chance), and you could probably move the scanning into a job. @crude glacier

[snow knoll]

Does anyone know what value of applyImpulse is good enough to keep an entity static in midair
I know that the applyKnockback equivalent value is 0.040763 but I'm since I'm using applyImpulse in this case I see no reason to use both

[crude glacier]

What is a job ☠️

[worldly pier]

A better question could be... what's the value of gravity in Minecraft?

[sharp elbow]

Not trying to be rude—but are you pulling my leg? lol

[snow knoll]

How i see it
Are you right: Yes
Could I edit my way of wording: perhaps, (but i also like making long questions intentionally) lol
I just didn't really think about it like that XD

[sharp elbow]

In theory you could apply the reverse of the entity's velocity:

function vec3_scale(vec, scalar) {
  vec.x *= scalar;
  vec.y *= scalar;
  vec.z *= scalar;
  return vec;
}

// ...

entity.applyImpulse(vec3_scale(entity.getVelocity(), -1));

[crude glacier]

No fr i never used runJob

[worldly pier]

Thats smart

[sharp elbow]

But I imagine you'll see the entity stutter a bit as the clients receive conflicting information. Might be better to solve this at the source and disable gravity if you can

[snow knoll]

That's a pretty cool way to do it honestly
Every time I see Sprunkles answer a question, I find it just fascinating to read
But would that work in a situation where velocity is also applied at the same time

[sharp elbow]

It's a feature in the scripting API that leverages generator functions to spread an operation across several ticks. Jobs take a function; each job is given a slice of time by the internal job manager each tick, and the job tries to execute as many operations as it can within that time. Naturally, on slower hardware this means it can take longer to complete.

[worldly pier]

I don't think there's any way of doing that, canceling its vertical component with another vector seems fine enough to me

[snow knoll]

Maybe the value is the same as real life where its acceleration due to gravity is just 9.81 m/s² in ticks instead of seconds

[worldly pier]

It would make more sense if it was in blocks instead of meters

[crude glacier]

Hmm, so what are you trying to say. instead of doing a job instantaneously, you just split it over chunks on different ticksusing generator functions and runJob ?

[snow knoll]

A block is a meter 💀

[worldly pier]

Oh, I didnt know that

[snow knoll]

Learnt it from camman18 like 4 years ago so I'm only so much more informed

[sharp elbow]

Mm, I suppose if you know what that velocity should be, you could add it and the negated existing velocity:

function vec3_add(vec1, vec2) {
  vec1.x += vec2.x;
  vec1.y += vec2.y;
  vec1.z += vec2.z;
  return vec1;
}

// ...

const myVel = {x: 1, y: 0, z: 0};
entity.applyImpulse(vec3_add(
  vec3_scale(entity.getVelocity(), -1),
  myVel
);

But you could also negate only the y-component of the velocity if you're just trying to fight gravity

[wary edge]

You can give slow falling too.

[sharp elbow]

That would help with client visuals, yeah. Makes gravity a little lighter

[snow knoll]

That's a great point
Definitely will be doing that

[sharp elbow]

Aye. Something like a for-loop could benefit from a job. Here's a basic example:

function* hundredOperations() {
  for (let i = 0; i < 100; ++i) {
    // Tells the job manager that it is safe to pause
    yield;
    doSomeExpensiveOperation(i);
  }
}

const myJob = hundredOperations();
// Pass job into the job manager
system.runJob(myJob);

In theory, the job manager should execute at least one iteration per tick. So this could take anywhere from 0 ticks to 100 ticks to run

But I honestly don't know the specifics of how the job manager works

[pale terrace]

what is the difference between using await?

I always optimize heavy operations per tick using await and I compared with runJob and the optimization is almost the same

[cold grove]

await is used for asynchronus behaviour, stops the execution until the promise is resolved or rejected

Does not have nothing to do with optimization practices

https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Statements/async_function

Generators can yield promises too i guess it has something to do(?

[pale terrace]

Well, it does, it's much more efficient when you distribute operations by ticks, but from what you're saying, runJob is better for these cases if you dont need to stop de code while the operation is playing.

[pale terrace]

afaik the only difference is that runJob doesnt stop the code execution unlike await

[remote oyster]

Both runJob and await do pause execution, just for different reasons. With await, execution stops until a Promise resolves:

for (const player of world.getPlayers()) {
    /**
     * doTask would be an asynchronous
     * function, making it appropriate to use await
     */
    await doTask(player);
}

Here, each iteration waits for its async task to finish before continuing. Once the code in doTask completes, it resolves its Promise, and the loop proceeds to the next player.

In contrast, system.runJob() pauses a generator at each yield, not because something finished, but to give control back to the game loop and resume on a later tick:

function* job() {
    for (const player of world.getPlayers()) {
        doTask(player);
        yield;
    }
}

system.runJob(job());

So the real difference is that await waits for async results, while runJob simply time-slices execution across ticks.

[pale terrace]

:O

Thank you for this info

[remote oyster]

A picture to help visually

[random flint]

I like putting the concept of await as "manual" tick-slicing, and runJob's yield as "automatic" tick-slicing.
-# "manual" because the dev decided where it should pause. And "automatic" because the game is the one that decides when to pause.

[honest spear]

I like putting the concept of await as "manual" tick-slicing, and runJob's yield as "automatic" tick-slicing.
I don't think its good puitting the concept of await as "manual" ticking-slicing

After all it doesn't much relates to ticks or tick slicing, if you refer to promise creation from system.waitTicks or other timing methods, then its more about promises than concept of await

[honest spear]

looks good even of its AI designed, i guess most of the text is written by you anyway but i can't unsee this misaligment

wait, the more i look at it the less i like it

the yield example is weird ngl

and misleading

[honest spear]

Imagine in what world we would live in if AI was actually good lol

[turbid canopy]

Is it possible to get whether or not a player is riding an entity

[open urchin]

player.hasComponent("minecraft:riding")

[turbid canopy]

Thx

How do I apply something to the ridden entity

[open urchin]

you can get the ride using

const { entityRidingOn } = player.getComponent("minecraft:riding")

[turbid canopy]

how would I validate this

I want changeSpeed to apply to the ridden entity

I realised a typo hold on

Sorry

[open urchin]

item.id?

[turbid canopy]

item.id should be itemId

Typo whoops

Changed it

[open urchin]

I'd do it like this

if (data.itemStack.typeId === "pr:md_vehicle_speed_changer") {
  const ride = player.getComponent("minecraft:riding")?.entityRidingOn;

  if (ride) {
    changeSpeed(ride);
  }
}

[turbid canopy]

Thank you

[crude ferry]

What is line 18?

[turbid canopy]

All line 18 has was that end bracket

[open urchin]

is that main.js?

[turbid canopy]

Yh

[open urchin]

should be data.itemStack

[turbid canopy]

Ok

[open urchin]

not sure why that would be a not a function error though

[crude ferry]

~~Please do Ctrl + A and click format document 😭 ~~

[turbid canopy]

I had a few a while ago and my whole addon broke

[turbid canopy]

What does that do

Oh right

Much easier on the eyes

Bridge used to do that automatically

[crude ferry]

Yeah.

[turbid canopy]

I did it

Reloaded and the issue is still there

Might be an issue with my manifest but last I checked it was fine

[open urchin]

oh you've removed the initialisation of player

[turbid canopy]

Where do I put that

[open urchin]

you could do data.source instead

[open urchin]

should be data.itemStack.typeId and player should be data.source

itemStack returns an ItemStack so it will never be equal to a string

[turbid canopy]

What if I do “let player = data.source”

[open urchin]

you could do that too

[turbid canopy]

I’ll try it

[open urchin]

should be a const though since the player won't change

[stray spoke]

score component exist?

[turbid canopy]

Ok

I’ll reload

I PRAY It works

That’s annoying

It still says that it doesn’t exist

[stray spoke]

it should be data.itemStack.typeId

[turbid canopy]

I did that

[stray spoke]

Oh someone already told

[turbid canopy]

Look at this

[stray spoke]

Can you send the error logs

[stray spoke]

We also need to know what code is in line 19

[stray spoke]

I see

You have typo

[turbid canopy]

Where

[stray spoke]

it should be subscribe

Not subcribe

[turbid canopy]

😭

[stray spoke]

Line 10

lol

[turbid canopy]

I’ll try it now

No error came up

New error

According to this my changeSpeed function is undefined

How do I define the entity

[turbid canopy]

Same code just without the subscribe having a typo

I don’t think score is a component

That might be the biggest issue

[stray spoke]

Yeah its my guess also

[turbid canopy]

I’ll remove it

[stray spoke]

I can't find score in entity components

[turbid canopy]

Well now it says it’s not a function since I removed that

[stray spoke]

What's the new code

If you want to set a scoreboard score, there's an api for it

[turbid canopy]

Hold on my laptop lost WiFi

There

[turbid canopy]

yes please

[stray spoke]

getScore doesn't exist

[stray spoke]

Alright

[turbid canopy]

oh

i could have sworn i saw it on entity class

for documentation

or is that getScores

[stray spoke]

function getSpeed(entity){
  const objective = world.scoreboard.getObjective("speed")
  const score = objective.getScore(entity)
  return score;
} // May fail if objective I'd doesn't exist

[stray spoke]

It's from scoreboardobjevtive class if you mean getting the scoreboard score

[turbid canopy]

I want to get the score and change it using the change speed item

[stray spoke]

You can by using setScore() once you get the scoreboard objective class

I'll type it in for example

[turbid canopy]

I added a console.log to the end of it so it tells me what speed I’m on rn

[stray spoke]

// you need to get the objective first
const obj = world.scoreboard.getObjective("speed")

// to get the score
const score = obj.getScore(entity)

// to set new score
obj.setScore(entity, 1)
// Or to add
obj.addScore(entity, 1)

[turbid canopy]

And I have to paste this into changeSpeed

I want to add score btw

[stray spoke]

alright use addScore instead

[turbid canopy]

Yup

[stray spoke]

much safer to check if objective exist first

[turbid canopy]

I’ll try what you gave me first

No errors

[stray spoke]

The score changed tho?

[turbid canopy]

No

Another error

Cannot read property of getScore of undefined

[stray spoke]

Yeah the objective didn't exist

You've to create one first

[turbid canopy]

Ohhh wait

I know the issue

I haven’t created my create objectives script

So it would be a playerJoin afterEvent right?

[stray spoke]

anywhere as long as it exists first before using score operations

[turbid canopy]

Now it has failed to resolve identity

[stray spoke]

it's like

world.scoreboard.addObjective("speed", "speed")

[turbid canopy]

main.js:14 is const score = obj.getScore(entity)

[stray spoke]

try this

[turbid canopy]

It may be because we aren’t using it

unless addScore is related to it

[stray spoke]

const identity = entity.scoreboardIdentity
obj.setScore(identity, 1)

[turbid canopy]

Replace line 14 with that?

[stray spoke]

append it on the very top of the function and replace the "entity" from functions like setScore/addScore/getScore into "identity"

I also want to see the updated code after this

[turbid canopy]

Replace all entity parts in the function with identity as well?

[stray spoke]

yes

[turbid canopy]

Wait if I place this above when I made obj wouldn’t it fail

Bc obj isn’t defined at that point

[lyric kestrel]

How come you're not using intellisense?

[stray spoke]

I meant inside changeSpeed

[turbid canopy]

I don’t trust it

It doesn’t work

[lyric kestrel]

Huh

[turbid canopy]

Can I send you what I’ve done

[stray spoke]

Yes

[lyric kestrel]

Intellisense shows you what you can use. A lot of your problems you're having rn can be solved by using intellisense.

[turbid canopy]

Do you mean the autocomplete? Or the AI

The AI is bad

The autocomplete is pretty good

import { world, system, EntityComponentTypes, DimensionLocation } from "@minecraft/server"
import { ActionFormData, MessageFormData, ModalFormData, FormCancelationReason } from "@minecraft/server-ui"

function createScores(player) {
player.runCommand ("function stats_start")
}

function getSpeed(identity) {
const identity = entity.scoreboardIdentity
// you need to get the objective first
const obj = world.scoreboard.getObjective("speed")

// to get the score
const score = obj.getScore(identity)


// Or to add
obj.addScore(identity, 1)

}

world.afterEvents.playerJoin.subscribe((data) => {
createScores(data.player)
})

world.afterEvents.itemUse.subscribe((data) => {
const player = data.source
if (data.itemStack.typeId === "pr:md_vehicle_speed_changer") {
const ride = player.getComponent("minecraft:riding")?.entityRidingOn;

    if (ride) {
        getSpeed(ride);
    }
}

})

[somber cedar]

This AI is good https://jaylydev.github.io/scriptapi-docs/meta/llms.html

[stray spoke]

Yeah that's good I think

[stray spoke]

Try running this

[turbid canopy]

Ok

[lyric kestrel]

this

[turbid canopy]

Oh that is great

Doesn’t come up for scripting tho

[lyric kestrel]

It does

[turbid canopy]

Not for me

[lyric kestrel]

Do you have the modules installed?

[stray spoke]

also make sure the scoreboard objective with id "speed" exist ingame

[turbid canopy]

It does

[turbid canopy]

Might not

[lyric kestrel]

npm i @minecraft/[email protected]

[turbid canopy]

I installed everything from what the wiki told me to get

The code doesn’t work @stray spoke

[stray spoke]

you might also try to log the updated score after the addScore line to check if it works

[stray spoke]

what error

[turbid canopy]

Invalid redefinition

At const identity = entity.scoreboardIdentity

[stray spoke]

I see

It should be

function getSpeed(entity)

not function getSpeed(identity)

[turbid canopy]

Ok

I reloaded

Obj is not initialised

IT WORKS.

Thank you so much @stray spoke

[stray spoke]

really?

[turbid canopy]

Yup

Just gotta tie up some loose ends

I don’t need help with them tho

[violet bloom]

addButtonList() and getSelectedButtonId() are not real vanilla ActionFormData methods.

[stray spoke]

Wise words. 🔥

[proven zinc]

What would be the best way to get the next air block above from a solid block? I have tried using getBlockAbovebut the raycast is stopped by the solid block and getTopmostBlock can skip valid locations

[lyric kestrel]

if (block.above().typeId === undefined)
{

}```

[warm mason]

Block.typeId can't be undefined

u should check if the block itself is defined or not

but block can be undefined only if it's in unloaded chunk or something like that

[lyric kestrel]

Ahh

[lyric kestrel]

Hmm ok didn't know that

[warm mason]

if u just use block.above() it won't be undefined

[lyric kestrel]

I thought it would've been undefined because there's no block there. Gimme a min to get back to my PC and I can do a proper check for him

[warm mason]

so, it should be like that:

function blockAboveIsAir(block) {
    return block.dimension.heightRange.max == block.y || block.above()?.isAir;
}

[lyric kestrel]

Oh, there's an isAir property now???

[warm mason]

it has been around for a very long time

[lyric kestrel]

How long has that been a thing? 😭

[lyric kestrel]

Oh 😭

[lyric kestrel]

@proven zinc use this one

[proven zinc]

Ah I wasn't clear, I wanted to scan for the next air block. As in if the block above is not air, keep going until it finds an air block

[lyric kestrel]

Oh

[proven zinc]

Solution I currently have is to use a block volume. Make a BlockVolume 1 block wide and the height to check from the location to consider. Then do a dimension.getBlocks for all air blocks.
Then use the getMin to get the lowest block

Looks like it works as intended, though not sure if its optimal

[warm mason]

/**
 * @param {Block} block 
 * @param {Number} [maxDistance] 
 * @param {(arg0: Block) => Boolean} [allowFunc] 
 * @returns {Block | undefined}
 */
function getGroundBlock(block, maxDistance = 7, allowFunc = (block => {
    if (block.isAir || block.isLiquid || block.y == block.dimension.heightRange.max) return false;

    const above = block.above();
    if (above.isAir) return true;
})) {
    if (block == undefined) return;
    
    for (let d = 0; d < maxDistance; d++) {
        let location = { x: block.x, y: block.y+d, z: block.z };
        if (location.y > block.dimension.heightRange.max || location.y < block.dimension.heightRange.min) continue;

        const ground = block.dimension.getBlock(location);
        if (ground && allowFunc(ground)) return ground;
    }
    
    return undefined;
}

[warm mason]

Can't remember when I was first asking dumb questions here

Now I'm pretty much flexible in script api and reading docs

[buoyant canopy]

You cast a ray from your block upwards and look for an air block

block.dimension.getBlockFromRay(
  block.location,
  {x: 0, y: 1, z: 0}, 
  {includeTypes: ["minecraft:air"]}
)?.block

[proven zinc]

I had tried that but the raycast stops whenever it hits a solid block regardless. The include Types just determines whether the result returned is undefined or the block

Hello can I use EntityHurtBeforeEvent now? Is it stable?

[snow knoll]

Yes
Has been stable for a bit

[warped kelp]

Yay

Is it better to use compared to the old after event for entity being hurt,

Cuz mine uses that for the parry system, etc, and it kinda sucks

[snow knoll]

Can you show me what it currently looks like?
I think it should work well for you
The only 2 reasons for why someone would need a beforeEvent of anything are:

• To cancel it
• To not need things like components in an item or entity (e.g. use_modifiers in an item)

Can someone explain to me how I would implement a breadth-first search algorithm into my codebase

I think my problem is wrapping my head around recursive functions

[dapper copper]

does anyone know if you can place a block with permutation thats a mob spawner? like the spawner block with an entity inside?
if not possible, i will just use structures
