Script API General

[shy leaf]

it also counts as 'not in rain'

[prisma shard]

oh

then

you have to make a for loop
then do y++ on the player.location
until the block isSolid()

[dim tusk]

No.

getBlockFromRay() exists

system.runInterval(() => {
  for (const player of world.getPlayers()) {
    const { dimension } = player;
    const { min, max } = dimension.heightRange;
    const weather = dimension.getWeather();

    if (location.y < min || location.y > max || weather === 'Clear') continue;

    const blocks = dimension.getBlockFromRay(player.getHeadLocation(), { x: 0, y: 1, z: 0 }, {
      maxDistance: max - location.y,
      includeLiquidBlocks: true,
      includePassableBlocks: false
    });

    if (!blocks) {
      // ...
    }
  }
});```

@shy leaf

[shy leaf]

yeah uh im already using this #1318313719377428602 message

getting if the block above is air is not an issue

but the rain depends on biomes

[dim tusk]

ahh, then good luck.

I just got annoyed with the guy above lmfao, you're literally saying if in the rain bro just keep insisting getWeather() is the solution

[prisma shard]

sorry

[pine grove]

Can I define a custom property inside a script instead of using entity's behavior json file and defining it there like below?

          "client_sync": true,
          "type": "bool",
          "default": false
        }```

[dim tusk]

No.

[random flint]

You can use custom entity for an accurate reading:

query.is_in_water_or_rain

Returns 1.0 if the entity is in water or rain, else it returns 0.0.

[shy leaf]

sadly it doesnt seem like an option since i need it for 'before the damage happens'

cant have a tick delay in the slightest

and no, i need to check it for victim, not the damaging entity

[wary edge]

???

[shy leaf]

combat test

[wary edge]

Im so confused what youre trying to do, stop the damage?

[shy leaf]

no uh

i actually just did resolve it a while ago

[random flint]

Then Do it before the check around the player attack range?

[shy leaf]

please no

[wary edge]

Because im confused, your message implies it isnt in BE.

[shy leaf]

the

hold on let me check my messages

[wary edge]

The Based answer ngl.

[random flint]

Combat Test 4 has separated mechanics from the official one

[wary edge]

I am aware.

My intent was to say it isnt in JE right now but it is in BE.

[shy leaf]

though the most problematic part is checking biomes to check if the biome can rain

like, im in savanna, why are you giving me dripstone cave

[random flint]

What are going to use the inRain detection for

[shy leaf]

for trident impaling

[random flint]

custom one?

[shy leaf]

no im recreating the entire combat

[wary edge]

But...again...impaling already does extra damage to mobs touching water in Bedrock.

[shy leaf]

uh yeah

and i was making that

[wary edge]

Im so confused.

[shy leaf]

ok uh

yeah i think i didnt explain whats going on

[random flint]

Probably custom damage calculation

you're recreating its mechanic right

[shy leaf]

the entire java combat actually

i did finish it a while ago but i forgot trident exists and

yeah

[random flint]

So you're importing Java's trident into Bedrock?

[shy leaf]

well not everything

im keeping the 'more damage against mobs in water or rain' cuz java trident sucks ASS

[random flint]

Are you planning to adjust its damage or keep it as default like vanilla?

[shy leaf]

i already set it to 9

i think its 8+1 in bedrock iirc?

and 9 in java

[shy leaf]

wait uh did you mean impaling damage or

trident damage

[random flint]

Trident damages (Java & Bedrock)

• Melee damage: 9
• Ranged Damage: 8
• Impaling adds 2.5 damage to each level.

So, you're keeping it as vanilla?

[prisma shard]

How do i execute a scriptevent

do i use runCommand

to start the scriptevent

[random flint]

system.sendScriptEvent() idk if its preview but its beta

[shy leaf]

ye

[distant tulip]

that like

[random flint]

Are u using damage sensor to cancel these damage?

[prisma shard]

what

then how would i

[shy leaf]

no, i did this

[random flint]

I see, so it's the melee problem.

Why not switch the player attack back to 1 if they hold the trident?

[shy leaf]

tick delay

and uh

theres no reason to

[distant tulip]

what your goal, i don't see any point in triggering scriptevent from the script, you already is at the script side at that point

[prisma shard]

https://discord.com/channels/523663022053392405/1323024128877527211

im using this

[round bone]

IPC?

[round bone]

why are you sending another script event?

I think you can directly plug the code for swing

system.afterEvents.scriptEventReceive.subscribe(({ sourceEntity: player, id }) => {
    if (id != 'script:swing') return;
    if (player instanceof Player) {
        // ur code
    }
})

[prisma shard]

world.afterEvents.playerJoin.subscribe(() => {
  player.runCommandAsync(`scriptevent script:swing`)
})

@distant tulip

i'd have to do this

[prisma shard]

here, it only executes when the scriptevent command is ran

[distant tulip]

Why do you need to send scriptevent to trigger a code
Just trigger it directly

[distant tulip]

Across packs? Sure
But in a single addon, there is no point

[prisma shard]

how

[distant tulip]

world.afterEvents.playerJoin.subscribe(() => {
  //put the code that you want to trigger here directly
})

[woven loom]

using funcs?

[prisma shard]

i have to use scriptevent

;-;

[distant tulip]

Ok

[prisma shard]

so how

[prisma shard]

its right?

[pine grove]

How to fix this?

[Scripting][error]-[Watchdog] Unhandled critical exception of type 'Hang' in behavior pack 'PACK'```

This did not work:

```system.events.beforeWatchdogTerminate.subscribe(eventData => eventData.cancel = true);```

[prisma shard]

events?!!??

there's afterEvents or beforeEvents

[pine grove]

Don't know. I got it from a past post. I'll try the other ones. Thanks.

👀

[prisma shard]

did u use ai

[pine grove]

Not in this case.

[woven loom]

you should see the docs

[round bone]

yup

it's just slowing down

and pretty useless additional logic

[dim tusk]

That's not valid btw, where'd you define player?

[prisma shard]

it was a- example

ofc event.player

[dim tusk]

Uhh no.

player doesn't exist in playerJoin.

[prisma shard]

then just world.getAllPlayers().forEach(() => {})

[round bone]

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

world.afterEvents.playerSpawn.subscribe(({ initialSpawn, player }) => {
    if (!initialSpawn) return

    player.runCommandAsync("scriptevent script:swing")
});

[dim tusk]

tf?

bro tryna be intelligent but failed.

[prisma shard]

thx

[distant tulip]

There is a native method

[prisma shard]

system.sendScriptEvent() ??

is it preview

idk

or beta

[dim tusk]

evemts 🤣 🫵

[distant tulip]

One question, why scriptevent?

[round bone]

IPC from player.json

[prisma shard]

@ minato

[round bone]

not in stable Minecraft yet

[prisma shard]

i see

is your mental health good?

[round bone]

I am only familiar with typing after and clicking intellisense after

[round bone]

it got better

[dim tusk]

mine always auto correct "beforeEvents" to "before events"

It's annoying...

[distant tulip]

Huh

[prisma shard]

?

[distant tulip]

Wrong channel
-# somehow

[round bone]

I am on PC

but on phone I have turned off auto correct

it's really annoying sometimes

[prisma shard]

system.afterEvents.scriptEventReceive.subscribe(({ sourceEntity: player, id }) => {
    if (id != 'script:swing') return;
 // my code
})```
cant i do this? (from here: https://discord.com/channels/523663022053392405/1323024128877527211)

[prisma shard]

will it not work without running the scriptevent on playerSpawn

[round bone]

it executes a scriptevent command as a player if he has just joined the world/server (Realms too)

[past coyote]

Its so funny

The API is so inconsistent, I can do the most invasive thing, spawn a structure from the world data...

but I can't get the beforeEvent for a player hurting an entity.

[round bone]

you can do some work-around this

but yeah, pretty inconsistent

[dim tusk]

just laugh.

[round bone]

tbh most of things are possible using some work-arounds

I only need slash commands and player's XUID and address

I know, that I can use a mod-loader like Endstone or just my own proxy, which also have more advantages, but I would like to do implement all of it directly in my add-on

[pine grove]

Oof, I am not in @minecraft/server 2.0.0-beta. What is the equivalent of this in 1.17.0?

[round bone]

can you send full code?

[cold grove]

Why?

[pine grove]

import { checkEntities } from "./entityChecker.js";

system.beforeEvents.watchdogTerminate.subscribe((event) => {
    event.cancel = true;
    console.warn(
        `[Watchdog] Canceled critical exception of type '${event.terminateReason}`
    );
});

system.runInterval(() => {
    checkEntities();
});

Code

It works in 1.18.0-beta but not in 1.17.0.

[cold grove]

Because its beta

Beta features are not accessible on stable, because its beta

[pine grove]

So there is no way to terminate it in an earlier version?

[cold grove]

Is beta...

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

You are in the latest stable version

[pine grove]

Well, I know. Thanks I guess.

[warped kelp]

I seee. Thanks, ima just spam chance in scripts with every hit they do :L

[humble lintel]

Does anyone know if using setDynamicProperty() on an item automatically replaces the itemStack with one that includes the dynamic property or do I have to replace it manually

[wary edge]

You need to set it back.

[humble lintel]

damn racist alright thanks

sorry i meant the unction is racist bc i wishd it already did that to me;

[granite badger]

Have you tried setting it via container slot class? https://jaylydev.github.io/scriptapi-docs/latest/classes/_minecraft_server.ContainerSlot.html#setdynamicproperty

[prime zenith]

I think they mean outside in the rain so if there in a house your funtion would still be true

[humble lintel]

would that work?

without having to replace item?

because im using an item with use modifiers and I don't want the event itemstopuse to run when i set the dynamic property

[thorn flicker]

lmao

[wheat condor]

with scripts can i get if an armor has a trim on it?

I am trying to get all death conditions

[round bone]

wdym?

reasons?

[chilly moth]

it didn't work when blown by creeper for some reason

or lava damage

[round bone]

which event are you using to handle entity's death?

[chilly moth]

entitydie

[round bone]

pretty weird

[chilly moth]

why

afterevents

[round bone]

wait, the player has died due to a creeper explosion or the creeper just blew up?

[chilly moth]

creeper blew up

and my entity died

blow up by creeper is what it said in chat

[round bone]

try using entityRemove event

it might be a bit more complicated to handle death, but will work all the way

[wary edge]

IF creeper blow up, creeper is gone.

[chilly moth]

it's not gone it returns in creative inventory

[prime zenith]

Creeper just wants a hug

is it possible to give a monster spawner with a mob inside

[prime zenith]

can someone get me an invinsible armor stand json ive tried but always failed my other project i had to turn off collision but wont work here as i need ppl to see the name of the armor stand

[random flint]

Set the size to zero

or just close to 0

[dim tusk]

animations 🤷

and btw, not possible to grab the chest's name right?

[prime zenith]

how does animations prevent ppl destroying my armor stand

[random flint]

damage sensor
custom_hit_test

[prime zenith]

I tried that with my other so ima need more then that

[valid ice]

You’re looking for a display name entity?

[prime zenith]

i want it so my armor stands cant be broken as there what displays the city owner

[valid ice]

Damage sensor component can cancel all damage

}``` there was still a small are that if hit you could kill the armorstand

on this project that is less effective as i need collision box

[valid ice]

Even if you do hit the hitbox of the entity you should not be able to kill it; the damage sensor makes sure of that

Consider opening a post in #1067869022273667152

[prime zenith]

is my syntax off i just tested with 2 2 hit box (dont do this if you want the armor stand next to water lol) it still breaks after a few hits

Is it possible to improve this script to have less lag?

[valid ice]

you can use native methods for those

world.gameRules.commandBlocksEnabled=false; and gamemode change event for the other one

[olive rapids]

Can you edit this script to your liking? I don't really know anything about scripts, and this was done by a friend who's usually very busy.

[lyric kestrel]

so...

It seems I forgot how to cancel block interaction with playerInteractWithBlock beforeEvent xD

[dim tusk]

You forgot how or forgot you can?

[lyric kestrel]

forgot how xD

I keep getting a read-only error or it doesn't work

I realised I can't put it in system.run, but still doesn't fix the not working part

Oh wait, I have it outside of system.run but still getting read-only error

tf

[dim tusk]

world.beforeEvents.playerInteractWithBlock.subscribe((ev, { block, player } = ev) => {

    ev.cancel = true;

    system.run(() => {
      // ...
    });
  }
});```

[lyric kestrel]

OHHHH

I had this

world.beforeEvents.playerInteractWithBlock.subscribe(e => {
    const { block, player, itemStack, isFirstEvent, cancel } = e;
    const blockType = itemStack?.typeId;
    cancel = true
  //....
})

I didn't realise I couldn't do that

[dim tusk]

You can destructure cancel

[lyric kestrel]

ye, I just did xD

[dim tusk]

that's why I did this

(ev, { block, player } = ev)

[lyric kestrel]

although, I'm a bit confused why structuring doesn't work for cancel

[dim tusk]

because it's not a property of the playerinteractwithBlock itself but only beforeEvents

[lyric kestrel]

ah

[dim tusk]

for simple, don't destruct when you cancel

[lyric kestrel]

ye

thank you

appreciate the help

[prime zenith]

Can you force close chat window from a chat event

[thorn flicker]

no

[past coyote]

how do I make this apply when the player has a tag?

[shy leaf]

well changing it would require component groups linked to events

[past coyote]

its not in here but I was trying to make it so if I have a tag I can't hurt any non-player entity, and if I have a different tag I can't hurt any player.

but im thinking it would be tedius to do.

[prime zenith]

Do dynamic properties follow the same integer limit of 2.147b

[past coyote]

32 bit yeah @prime zenith

2,147,483,647

[deep yew]

I am trying to use player TP and ticking areas, while also teleporting the player 10k blocks away and saving a structure then deleting those blocks and then TP back. This causes issues and varies in severity depending on network speeds, causing loss or deleted structures. What would be the fastest way to load chunks that aren't in render/simulation distance?

[slow walrus]

tickingarea or a ticking entity are the only ways

and they both take a few ticks to actually load the chunks

[deep yew]

what is a ticking entity?

One that has the tick component?

[slow walrus]

an entity that has the tick world component

[deep yew]

I tried making one and failed, so maybe not that

I know it can't all be done instant or fast, but I also need to save and unload those blocks using structures for when that player leaves

because it's a plots system that loads and unloads but is far away from spawn

[slow walrus]

https://learn.microsoft.com/en-us/minecraft/creator/reference/content/entityreference/examples/entitycomponents/minecraftcomponent_tick_world?view=minecraft-bedrock-stable

[deep yew]

Do ticking areas cause chunk loading or do they just keep the last player-loaded chunks intact?

[slow walrus]

ticking areas load the chunks

the chunks have to be loaded for ticking to happen

[deep yew]

that sounds like it counters itself

It sounds like I'd want to make a tickingarea for each player that isn't currently at their plot, but there must be 1 tickingarea for spawn and 1 for each player

[slow walrus]

why would you need tickingareas for players who aren't at their plot?

[deep yew]

If they leave or unload the plot, the ticking area will have the chunks loaded and unload the island and remove the blocks from the world. I am thinking I can just add a ticking area when they leave and not try to worry about it being super fast like 5 ticks or less and more like 5 seconds or less, but I was just trying to find fast efficiency

[ivory bough]

is there any way to get the current render distance of a player?

[subtle cove]

Player.prototype.clientSystemInfo.maxRenderDistance

[distant tulip]

Use the ticking components in a dummy entity, it is way better

[deep yew]

Way better, how?

[distant tulip]

Not limited in term of count, and you have much control over it sense it is an entity

[ivory bough]

But this shows the maximum render distance possible on that device. Not the player's render distance

[deep yew]

I immediately agreed when you said it because of the count of the entities not being as restricted, but I wonder about the loading and persistence of the entity when it's far away

or it just keeps itself loaded because it's ticking?

[distant tulip]

You have control over that too

[deep yew]

Over what, the persistence and stuff?

[distant tulip]

Yeah

[deep yew]

Simply, all I need is a way to keep some, preferably all, islands loaded basically at all times so everything that needs to tick does tick and when a player unloads the plot, it doesn't lose data or chunks

and I need it to work when the player's device is slow

as I know from the alt account on the laptop next to me, it can cause some good issues

[chilly moth]

how do I check if entity is tamed before death

[dim tusk]

get tameable componentjs const tameable = Entity.getComponent('tameable'); tameable.isTamed

[deep yew]

Works like a charm, you're amazing

[chilly moth]

I want to store that, it is tamed before death

[prisma shard]

dynamic property

[chilly moth]

how

[dim tusk]

Entity.setDynamicProperty('<name>', <value | Boolean | string | Vector3 | number>); Entity.getDynamicProperty('<name>');

[prisma shard]

btw you'd have to use entityDie event

wait no

your storing it before death.

[dim tusk]

use dataDrivenEntityTrigger to detect the tabe

[chilly moth]

ok

[dim tusk]

Or use playerinteractwithblock and get the tameable items

[chilly moth]

I am using command

[prisma shard]

aw hel naw

[dim tusk]

for what?

[chilly moth]

check
If died entity is tamed and revive it tamed

it wasn't checking if died entityis tamed but revied entity was always tamed and it's chosing the last killed entity and saves it's data for revival
leading to making the killed wild pets revive being tamed

[chilly moth]

got it working now it store data only for tamed entity

[chilly moth]

I don't know how it will affect multi-player though

Player.nameTag = 'Test' is already enough

tho in chat's it doesn't change.

[prisma shard]

can't i see my own name tag

[dim tusk]

Wdym const see my own name tag? You can't in the first place tho.

[prisma shard]

i am simulating a player in the game right

• go third person

• look at my own player

• can i see my name tag?

thats what i mean

No.

use a dummy entity and ride the player or tp them.

[ivory bough]

Is there any way to cancel vanilla commands? Like for instance, "kill @a" any way to cancel this?

[round bone]

if you're not using BDS, then this solution is not for you

you can detect CommandRequest packet and cancel it, there's no really solution to detect certain commands via Script API

[ivory bough]

hey does bds support download links? If so, if I call that where will it download the file?

[round bone]

what do you mean by file installation?

in script? you can't even handle these files

[ivory bough]

Oh k

is there a way to detect the color of water in a couldron?

[warm apex]

Does anybody have any tips with folder/structure layout for scripting? I'm pretty decent with coding, but because I'm self taught I don't have a good way of knowing when to separate things into different files (I usually end up with most things running on main.js with a few folders for my own math related classes like vector maths or trig)

((Sorry if this is a bad place to ask))

[cold grove]

Always go for readibility and modularity

I personally dont like to put things on the main script file
I separate events in different files, same with server forms

[warm apex]

Oh yeah, I've been doing that more recently too but it's kind of a struggle working solo and trying to figure out what would be readable for others ^^" the modularity thing is something I've been looking to get around to as I've been thinking of setting up my own libraries beyond my maths ones

Thanks ^^

The cat destroyed all the string

[prime zenith]

Im surprised at how msny structures a script can make before it has idmssues

[unique acorn]

how much

[prime zenith]

I made 20k before a watchdog error

Whats the game rule to turn off the recipe unlocking

[unique acorn]

/gamerule recipesUnlock false

[prime zenith]

If im making a rts game about attacking and conquering players ciries should input the cities underground making you need to mine in order to find other cities

[prime zenith]

I had ai generate random names for my cities i liked it up until 1 of the cities name was volsungstead

[unique acorn]

very European name

[prime zenith]

Hmm if its a realistic name even if foreign ill keep it i thought it was over the top

[prime zenith]

I was this many years old when i learned BigInt was a thing

Considering i got it to acuratly display the result of 123456789 × 123456789 which is way past integer limit that is cool

[chilly moth]

I want to set up a command script to see list of tamed pets by owner can anyone help

[prime zenith]

New habbit to get into add n to every number for dynamics and integar limit becomes a non issue lol

[ivory bough]

any way to show entities that are only visible for 1 player?

[unique acorn]

I don't know any way at the moment

[prime zenith]

I dont think so but if im wrong do let me know

[warped kelp]

How do I fix this?

[Scripting][error]-Plugin [The Black Silence Trial 1.2 - 0.0.1] - [main.js] ran with error: [ReferenceError: 'world' is not defined    at <anonymous> (custom/on_hit_gebura_2.js:12)
]

[distant tulip]

Import world

[warped kelp]

OHh

I forgor

I forgot the most important thang in a script

[chilly moth]

can anyone help provide snippet
im trying to list player tamed entities
by making list command but pet is not getting listed 😕

[distant tulip]

You are using tameable component?

[chilly moth]

yes

[distant tulip]

It doesn't work for vanilla entities or any entity that remove the component ehen tamed

[chilly moth]

than what I supposed to use¿

it revives tamed pets untamed ,and retames i did it through entity die and entity spawn

the list is available after at least all pets are killed once

any other way?

can the same be done using type_family
@distant tulip

[distant tulip]

wdym

[chilly moth]

using type_family to get tamed

[distant tulip]

How...

That doesn't make much sense

Ok i could thing of a way, what if we used the data driven event and prevented the removal of the tameble component for a second untill we stored the player id somewhere @chilly moth

There is a thing in that event called commponentGroupToRemove

[chilly moth]

does bedrock support delay

[distant tulip]

In what way

[chilly moth]

[prime pine]

not sure where to post this or ask about it but does anyone know how i can fix this

have the better on bedrock, a magic way relics and rings true weapons and java combat addons on

worked fine for 40 in game days

then randomly the world froze but i didn't

and this popped up

tried removing and readding the packs

still doesn't do anything i unless i remove all the packs

then the world works

1.21.51

[chilly moth]

so their isn't any method to store pet dynamically?

[fast lark]

how can i make a timer of a hour and when it finish someting happens

[sharp elbow]

Do you have your content log enabled? Is it saying what is causing the exception?

[unique acorn]

Method 1: declare a variable and assign the value 3600 to it, then use a runInterval to decrement 1 number every second then check if the number is equal to 0.
Method 2: make a variable with the value Date.now() then every once in a bit keep checking if the current date is bigger than that variable + 3600000.
Method 3: same as method 2 but instead use system.currentTick and check if the current tick is bigger than that variable + 72000

[sharp elbow]

Method 2 is your most time-accurate choice. There is no guarantee that the server's tick rate per second will be consistent enough for an hour.

[chilly moth]

I tried adding tag to custom mob and this happened

[prime pine]

no lemme turn it on and see

[ivory bough]

How exactly could I use this? Will I make a property for my desired entity and then set its value and then make the geo file's query in molang in RP the property?

[wary edge]

Correct!

[prime pine]

couldn't get a screenshot cause the whole pc froze but it sayed Novelty api hangtime 132482ms then said shutting down server

[sharp elbow]

Hm. You're sure having any one of those packs applied caused the exception?

[prime pine]

not sure cause it was perfectly fine

till i download an older version of the relics addon

cause it had a feature that wasn't in the newer on

one

and when i removed the new version and added the old one

it worked fine for a few hours

then randomly the world just froze

but i was still able to move

like lag in a multiplayer world

then it won't let me play the world

unless i remove all the addons

made a new world same exact addons

works perfectly

[sharp elbow]

Does it seem to occur when you perform any particular action?

[prime pine]

can't even get in the world

no but i just removed the novelty api from active behaviour packs and got the same message

[sharp elbow]

Ah, it's also in A Magic Way

[prime pine]

what could be the cause

also why does it persist despite not being enabled

novelty api isn't active but i still get that message

[sharp elbow]

I suspect that A Magic Way has merged the contents of the Novelty API into its pack, so they are basically carbon copies

[prime pine]

is there a way i clone the world without the magic addons then delete everything and download them from the web so they start working again

[prime pine]

they have a common lib java script

[sharp elbow]

Whatever either copy of these APIs are doing is causing Minecraft to think too hard

[prime pine]

ah huh

this novelty manager is in both

could that be the problem?

[sharp elbow]

I wouldn't think so, as Minecraft should be keeping these modules separate. It should be redundancy at worst

[prime pine]

ok then

was it me removing the behavoiur pack

cause it said it might cause problems

[sharp elbow]

Not sure. It is not easy to ascertain the cause without a stack trace, which Minecraft has so conveniently left out for us

There's a lead, at least, but the API is deeper than I first thought

[prime pine]

any temp solution i can try

to just atleast get the world back

like can i somehow clone the world istelf without the addons

[sharp elbow]

You could make a copy of the world, then remove the add-ons from the copy, I suppose

[prime pine]

then re add them?

[sharp elbow]

Re-adding them may very well re-introduce the issue

Actually, had a thought. Could you send me the world? I can try debugging it

[prime pine]

it's 150mb need to upload it to something

you willing to trust a mediafire link

[sharp elbow]

haha, sure

[prime pine]

or is there somethign you trust more

[sharp elbow]

No worries with Mediafire

[prime pine]

https://www.mediafire.com/file/jrxkbw22suwq586/6_foot5_.mcworld/file

idk if it did it right

just made a .zip with winrar

then renamed it to .mcworld

[distant tulip]

seem to work "fine"

[prime pine]

what

why won't it workf or me

[prime pine]

are all the mods on?

cause i'm supposed to have a katana in the first slot

and a dane axe in the last slot

and in your screenshot they're not there

[distant tulip]

yeah

[prime pine]

I'm so confused

[distant tulip]

actually, no
you removed the one causing the hang

[prime pine]

oh yeah

should i send that one?

[distant tulip]

this?

[prime pine]

yeah

could this just be a weak pc issue?

[distant tulip]

nope, that addon is causing it

[prime pine]

hhmm

so just removing it will fix everything?

but it's not even active and i still get that message

[distant tulip]

i didn't get it in the world you sent, only when i added it

[prime pine]

yeah

so

any ideas

[distant tulip]

let me look into it code

this is the worse addon i ever seen in term of performance

[prime pine]

lmao

[trim cedar]

lemme see that code i gotta get me a good laugh

it cant be that bad

:clueless:

[prime pine]

it is a older version cause the newer version straight up didn't work at all for me

[trim cedar]

DEAR GOD THE TPS, THE FRAME LOSS

[prime pine]

so what're your essentially saying

is that it's over and i'm cooked

[ivory bough]

Any way to make my entity break blocks like the player but not instantly? I know its not possible with entity.json

[night acorn]

does anyone know how to actually spawn / create a simulated player from the gametest module

[unique acorn]

import { world, system } from "@minecraft/server";
import * as GameTest from "@minecraft/server-gametest";

GameTest.register("AI", "attack", (test) => {
  const player = test.spawnSimulatedPlayer({
    x: 1,
    y: 2,
    z: 1
  }, `Player-Name`, "survival").maxTicks(100).structureName("structure").tag(GameTest.Tags.suiteDefault);
});

you do need a structure in your BP

replace structureName with that

[night acorn]

ok

[past coyote]

Grok is amazing @inland merlin

I fed it my entire codebase bit by bit, and had it refactor everything, it found stuff that was being called 600 times per second and dropped it to 20 per second. Like it found stuff that I had no idea was causing performance issues.

I also fed it my CPUPROFILE capture, so it had more context of what might be causing performance issues

it actually improved the sound system script too, like audio for waves plays the way I originally wanted it to, but I never noticed!

Its pretty insane, it would have been HOURS of debugging and comparing profiler data, but it was done in 10 minutes.

Thank you so much for letting me know about it, normally I dont touch elons stuff but grok really is just good at what it does objectively.

[inland merlin]

Glad it's helped you! It's saved me hours of work as well!

[past coyote]

Its been like integral to my development workflow 😭

[distant tulip]

Grok 3?

[untold magnet]

uh, count++ will increase the counter, count-- will decrease it?

( making sure )

[wary edge]

Yeah.

[pulsar pike]

hi guys i have this code

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

const NightStoneOnUse = {
    onUse({ source }) {

        const item = source.getComponent("minecraft:equippable").getEquipment(EquipmentSlot.Mainhand)
        source.runCommand("time set night")
    }
};

world.beforeEvents.worldInitialize.subscribe(({ itemComponentRegistry }) => {
    itemComponentRegistry.registerCustomComponent("SurEx:NightStoneActivate", NightStoneOnUse);
});

i am trying to get the name of the item to reuse the code and just get item name and apply the necessary time change.

my question is where can i see more about the "getEquipment" and what data can i get out of it.

item.name doesnt give anything, item.typeId, nothing. and thats only from checking discord history but could f ind nothing in the wiki

[unique acorn]

https://jaylydev.github.io/scriptapi-docs/latest/classes/_minecraft_server.ItemStack.html

[chilly moth]

minecraft tameable component gets removed on tame so check
has component is_tamed
@distant tulip

it worked for me

[distant tulip]

that doesn't work for getting the owner

[chilly moth]

I haven't tested multiplayer so I don't know about that

[pulsar pike]

thank you

[pulsar pike]

about itemStack.amount, my item is set to max Stack 1 but when i want to remove it using ".amount" it says that my item needs to be greater than 0
are there other ways to remove it other than the amount property?

[unique acorn]

source.getComponent("minecraft:equippable").setEquipment(EquipmentSlot.Mainhand, null)

set the slot to null, that's a way to remove an item

[pulsar pike]

thank you

[fallow rivet]

Is it possible to place a sign with writing inside?

[unique acorn]

yes you can use the sign component

const block = world.getDimension("overworld").getBlock(location);
const signComponent = block.getComponent("sign");
signComponent?.setText("Hello, world!");

[fallow rivet]

Thanks

[untold magnet]

uh, which component can detect the player movement? besides that input key component thing

[dim tusk]

none.

[untold magnet]

ah,

[dim tusk]

You'll use velocity

[dim tusk]

Player.getVelocity()

[untold magnet]

i see,

[untold magnet]

but, that will be affected if the player is moving but by another thing like riding a mob or on the minecart, right?

[dim tusk]

yes.

Everything as long as he's moving the getVelocity() it will return values.

[untold magnet]

to make sure that not happened, i should detect it only when the player is not riding another mob

[dim tusk]

Either use beta or wait for it to be stable next version

[untold magnet]

ah, its not even stable

well, my addon isn't for marketplace anyway so i can use it

[untold magnet]

input key is not stable too right?
like i can use it to detect the player movement ( north south east west )

i dont have to detect up/down,

[dim tusk]

getMovementVector is beta in .60

[untold magnet]

well, detecting the player movement is beta anyway right?

[dim tusk]

that's literally method to detect movements

I mean WASD movement detection

[untold magnet]

i mean is there anything stable i can use to detect if the player is moving or not?

[dim tusk]

stable - getVelocity()
beta - getMovementVector()

[untold magnet]

i see,

[dim tusk]

What I mean by stable is a stable version of the script.

1.17.0 or 1.18.0-beta

system.runInterval(() => {
    for (const player of world.getPlayers()) {
        const { inputInfo } = player;
        const movement = inputInfo.getMovementVector();

        const normalizedX = Math.abs(movement.x) > 0.2 ? Math.sign(movement.y) : 0;
        const normalizedY = Math.abs(movement.y) > 0.2 ? Math.sign(movement.y) : 0;

        if (normalizedY > 0) console.error('forward');
        else if (normalizedY < 0) console.error('backward');

        if (normalizedX > 0) console.error('left');
        else if (normalizedX < 0) console.error('right');
    }
});```

[untold magnet]

1.17.0

[dim tusk]

This one is for 1.18.0-beta

[untold magnet]

i know, but im not using beta,

[marsh pebble]

what's the run command to go to that develoment pack

[cold grove]

Huh?

[dim tusk]

%LocalAppData%\Packages\Microsoft.MinecraftUWP_8wekyb3d8bbwe\LocalState\games\com.mojang??

[marsh pebble]

too lae

already found it

CODDY OPP

WHAT ARE U DOING HERE

[untold magnet]

uh, is it possible to detect if the player is riding a mob?

[unique acorn]

const ridingComponent = player.getComponent("riding");

const entityThatThePlayerIsRidingOnTopOf = ridingComponent?.entityRidingOn;

if (entityThatThePlayerIsRidingOnTopOf.typeId == "minecraft:horse") {
  //run code
}

[untold magnet]

i dont have to detect the mob, just checking if the player is riding something or not.

so i just have to get the riding component,

dude json ui broke my scripts skills

[unique acorn]

you can check if the entityRidingOn exists

if (entityThatThePlayerIsRidingOnTopOf) {
   //run code...
}

[warped kelp]

What script can I use to limit a specific mob to only allow 1 to exist at a single time?

[dim tusk]

use entitySpawn or runtInterval to detect if the ID spawned is already in the world, if yes remove the spawned entity.

to check entities in the world just do entity.dimension.getEntities({ type: '<id>' })

[dim tusk]

Umm, I'm everywhere. Wdym?

[warped kelp]

I see, thanks

[dim tusk]

why you're so surprised as if you don't see me everyday.

[warped kelp]

Is this right?

function canSpawnEntity(og:roland_tier1) {
  const entities = world.getDimension("overworld").getEntities({ type: og:roland_tier1 });

  if (entities.length > 0) {
    return false;
  }
  return true;
}


world.afterEvents.entityCreate.subscribe((event) => {
  const entity = event.entity;

  if (entity.typeId === "og:roland_tier1") {

    if (!canSpawnEntity("og:roland_tier1")) {
      entity.remove();

      console.warn("Only one tier_1 can exist at a time!");
    }
  }
});

[dim tusk]

entityCreate where'd you get that?

[warped kelp]

A hallucination from deepseek 🔮

[dim tusk]

world.afterEvents.entitySpawn.subscribe(({ entity }) => {
  if (entity.typeId === 'minecraft:armor_stand') {
    const armorStands = entity.dimension.getEntities({ type: 'minecraft:armor_stand' });
    if (armorStands.length > 1) {
      entity.remove();
    }
  }
});```

[dim tusk]

BRUHHHHH.

[warped kelp]

Lmao. It sounded smart, too. Create entity? Waw

[warped kelp]

What if I'm not using armor stands? Like, what do I place in the const armorStands =

[dim tusk]

Change the variable name.

it can be anything you want.

[warped kelp]

Ah, right. I'll place the entity's name

[dim tusk]

world.afterEvents.entitySpawn.subscribe(({ entity }) => {
  if (entity.typeId === 'minecraft:creeper') {
    const entities = entity.dimension.getEntities({ type: entity.typeId });
    if (entities.length > 1) entity.remove();
  }
});```

[warped kelp]

{
world.afterEvents.entitySpawn.subscribe(({ entity }) => {
  if (entity.typeId === 'og:roland_tier1) {
    const BlackSilencephaseI = entity.dimension.getEntities({ type: 'og:roland_tier1' });
    if (BlackSilencephaseI.length > 1) {
      entity.remove();
    }
  }
});```

Ima remove the numbers on the name

[dim tusk]

Why make the variable names complicated?

[warped kelp]

Ikr? Idk, makes it feel complete

[dim tusk]

Simple as this is already straightforward

[warped kelp]

Alright boss, thank you boss 💯

[scarlet sable]

Is there a way to know what pixel in a block the player is looking at?

Or smtg close to that

Not what block

[dim tusk]

faceLocation.

[scarlet sable]

How?

It gives the angle of the head

[dim tusk]

Angle of head? What?

[scarlet sable]

What does face location give?

Maybe I'm wrong

[distant tulip]

Add hitBlock.location to faceLication

[scarlet sable]

Ok

[dim tusk]

world.beforeEvents.playerInteractWithBlock.subscribe(({ block, faceLocation }) => {
  console.error(JSON.stringify(faceLocation));
  console.error(JSON.stringify(block.location));
});```

[scarlet sable]

[boreal siren]

Guys, I faced a very difficult task, I need a database with a small and non-critical number of minuses. I thought to use a dynamic property of the world, but faced a problem in the form of speed and volume of data, as well as an optimization problem. Then I thought to use NBT, but I realized that it also has problems, in the form of inconvenience in management, complexity of control and use in the future. Before that I thought to use ScoreBoarb, but immediately refused this torment, almost the same problem as a dynamic property, but it also supports only the method (key, value in a digital type) and in addition it loads the world very much, as well as tags.

Do you have any ideas on how to create a database?

[slow walrus]

what do you need the database to do?

dynamic properties are generally the best in-game database option

if you're having issues with performance, then you probably just need to optimise how you actually store stuff

[prisma shard]

um, why do people use scoreboards to make a entity kill counter?
woulldn't this be easier?

let counter = 0; 
world.afterEvents.entityDie.subscribe(({ damageSource.damagingEntity: player, deadEntity}) => {
  if (player instanceof Player) {
    counter++
  }
  player.onScreenDisplay.setActionBar(`Kill Counter: ${counter}`)
})

[thorn flicker]

that would not be good for multiplayer support.

also the variable's value wont save when you leave the world or reload the script

[boreal siren]

I want to create a base for developing different mini-games (that is, a basis or foundation for further development), such as SkyWars, BedWars, ... and the basis for this is a database in which information is stored (arena locations, statistics, settings), a system (or, more simply, a core or template with which it will work).

and that's why the option with the dynamic property is not suitable for me, its functionality, as it seemed to me, is not suitable

[dim tusk]

No Multiplayer support, since you did increase the variable itself, means everyone was affected, you need to use object first then every player.id add a number, second it won't save every time they quit or the world is close.

const kills = {};

kills[player.id] = (kills[player.id] || 0) + 1;```

I think you should already know why they use the scoreboard.

[prisma shard]

hmm

right

yeah okay

thanks guys

[prime pine]

anyone know how to fix this or if this is an issue

is there something wrong with the code

[slow walrus]

that's main.js. The error is in Amputate.js

[prime pine]

there is no Amputate js

not in the Novalty API script folder atleast

[slow walrus]

there has to be an Amputate.js somewhere, since it's being used, and it never said it's inside the Novalty API

[prime pine]

but it said slowdown from novelty api

[open urchin]

they are separate messages

so might be from separate packs

[prime pine]

oh yeah i found it

was in a seperate pack

but they both happened simoultanuesly when i did one specific actions

i got grok to explain it makes sense

and fix works

[scarlet sable]

Have anyone here made a stonecutter recipe before?

[ivory bough]

Any way to make the host of a world unable to use commands even if cheats are enabled?

[sharp elbow]

Ooh! What was the issue?

[prime pine]

well 2 addons where conflicting so i fixed that first cause the amputate constantly checked for a change to the player

and placing or removing a ring from the accesory menue

would trigger it

then to reduce the slow down thing

it basically just reduced runtimes and shi ion really know

but like making it run every 5 ticks instead of every tick

and some other stuff

i just told it to optimise the code

and copy pasted

[sharp elbow]

That does seem like some neat software

[prime pine]

don't get a slowdown at all anymore and works fine

[prime pine]

yeah low-key unfair

i wonder if i could literally get it to code an addon for me without doing anything myself

besides resources and textures which even that it might be able to do haven't tried

[untold magnet]

uh, how am I going to detect the itemStack data? ( like detecting the water bottle, its id is just potion thing,

[unique acorn]

potion component

[untold magnet]

getComponent thing?

[unique acorn]

yeah but it's in beta

the potion component is in beta

[untold magnet]

well, i think im good with make players sick with all kinds of potions

[ivory bough]

Any way to make the host of a world unable to use commands even if cheats are enabled?

[unique acorn]

in a BDS you can with the @minecraft/server-net module

[ivory bough]

but this mod is not for bds any other alternative way?

[unique acorn]

no

[coral ermine]

How to spawn named entity with spawnEntity?

[unique acorn]

const spawnedEntity = dimension.spawnEntity("name", location);
spawnedEntity.nameTag = "Bob"

[untold magnet]

uuh, is it possible to detect when the dynamic property number has been changed?

[midnight ridge]

check the value

a system.runInterval will be enought

[untold magnet]

but how exactly

detecting if the value have been changed and run something for once

[midnight ridge]

the first value of the dynamic property is it fix?

or it is variable

[untold magnet]

the value will be updated every like a minute or via other things like interacting or walking, so i have to detect if the value have been changed or not.

the value i am talking about is from 0 to 20
lets say the value is 0 and it has been updated to 5 or 6, the script will detect that update and run something for once.

[midnight ridge]

const value = world.getDynamicProperty("value")
if(value === 5){
//do somthing
}  ```

[untold magnet]

do something for once and no more,

• its inside of an interval

[midnight ridge]

is it for players?

if it is

[untold magnet]

yup,

[midnight ridge]

then give the player a tag

like

[untold magnet]

instead of using tags, how about turning on/off another dynamic property?

[midnight ridge]

set another dynamic

and controle it value

[unique acorn]

let previousValue = world.getDynamicProperty("name");

system.runInterval(() => {
  if (world.getDynamicProperty("name") !== previousValue) {
    //run code...
  }
  previousValue = world.getDynamicProperty("name");
}, 2);

this could work

[midnight ridge]

i thought about it too but he said he want to turn it on and off

or idk

[untold magnet]

uh,

[unique acorn]

what does that mean

[untold magnet]

my whole entire issue is with titles, i don't want to spam the titles and for some reason its kinda bugged for some reason

like when i change the value and send the title with the new dynamic property value, it will show the previous one instead of the new one

[unique acorn]

it only runs once btw

[untold magnet]

i tried having it inside of a runTimeout and it has the same exact issue

[midnight ridge]

do have an existing code?

[untold magnet]

if (hyd === 0) {player?.setDynamicProperty('hyd', 5); player?.onScreenDisplay.setTitle(xHydTB:${hyd})};
it should update the dynamic property value and apply it into the title, which did update the value but didn't apply it to the title

[unique acorn]

what did you assign to the variabe "hyd", and are you saying that it should show the new value in the title?

[untold magnet]

let hyd = player?.getDynamicProperty('hyd');

[unique acorn]

world.setDynamicProperty('hyd', 'value');
let hyd = world.getDynamicProperty('hyd'); // hyd will have the value 'value' assigned to it.
world.setDynamicProperty('hyd', 'newerValue')
console.log(hyd) // should return 'value' and not 'newerValue'

Here is an example, so in your code it should show xHydTB:0 to the player

does that make sense

I tried explaining it

if that is even the issue you're having

[untold magnet]

well I'll try to fix it somehow

well i think i know how to fix it, instead of using a good method that is causing this issue, I'll use my bad method to make it worke 100% better than ever

so let's just remake somethings...

[untold magnet]

fixed,

i literally used if else and it fixed everything, literally everything

[fast lark]

how can i store a string in a dynamic property

[dim tusk]

store a string in dynamic property? Or make the values stored by dynamic property into a string?

[fast lark]

first one

if its possible

[dim tusk]

Just pass a string.

String, Boolean, Number, Vector3 are possible

[distant tulip]

<player|item|world|entity>.setDynamicProperty("key", "string")

[dim tusk]

blocks when 🥺

[distant tulip]

Never

[fast lark]

thx

[shut vessel]

what didn't work ?

                        case '!unfreeze':
                        if(!eventData.sender.hasTag("host")) return;
    var arg = msg.message.slice(11).toLowerCase();
    if (arg.startsWith("@")) {
        arg = arg.slice(1);
    }
    
    for (let i = 0; i < players.length; i++) {
            const player = players[i];
        eventData.sender.runCommandAsync(`inputpermission set ${arg} movement enabled`);
    }
    break;```

[shut vessel]

I would like that when the command executes the command according to conditions but it tells me that the "case" does not work and that the error is this famous "case"

[valid ice]

Can you send the error you’re getting

[shut vessel]

yess

[slow walrus]

you're missing the closing } of the for loop. also, please fix your formatting

[shut vessel]

i don't have error but my player name dont working

the msg isnt not definited

[slow walrus]

?

what player name

there's no player name in that snippet

[shut vessel]

I have to add a "PlayerName" in const?

[slow walrus]

I got no clue bro

[shut vessel]

okk

[woven loom]

We have so many database solutions now, I believe we should make a list and add it to the wiki, so help people find them easily.

[simple zodiac]

or teach people aproches to not rely on these hacky solutions

[woven loom]

Why?

[stuck ibex]

probably redundant cus dnyamic properties are already good

[woven loom]

Hmm true IG as I have not seen anyone use more than 32kib in one go yet.

[distant tulip]

i did, but i felt like that was not efficient so i changed my method
i believe Jayly did too, although i am not sure if that was for testing or what

[slow walrus]

waiting for someone to make a SQL database

[stuck ibex]

a wiki section that guides people how to use external databases would be great

[chilly moth]

@distant tulip you can save player id with dynamic property

I tried it,
it saves my gamertag name

[distant tulip]

your method is not multiplayer friendly

[chilly moth]

hm I guess so

[chilly moth]

does anyone knows why sidebar gives number to every line?

[ivory bough]

How to detect if a block was broken in a specific structure?

[distant tulip]

not possible

[ivory bough]

What about using the getting block permutation through structure class and see if the block exists or not according to the structure's origin

[distant tulip]

that could work, but only with custom structures

[ivory bough]

Yeah I am using my own custom structure. Also does the structure manager return structure through the getStructure or whatever it was only if it is placed somewhere in the world or if its in the game files?

[distant tulip]

game files or saved using structure block or command or script api

[ivory bough]

How to make it run only if it is placed on the world? Doesn't matter if it was loaded with structure manager or features. I will make it generate through whatever works

[distant tulip]

make a custom ticking block that run some code that let you know it is loaded

[ivory bough]

How?

[distant tulip]

custom components

[ivory bough]

Yeah but how to know if it's loaded what are things in scripting api that could help me make this?

Related to what I wanna make

[distant tulip]

on tick trigger automatically

[ivory bough]

Ok maybe I am dumb but how to make it detect when structure loads?

Ok maybe I am just not understanding

Oh wait I think I should make a dummy block in my structures and then use it's position to get the blocks in structure

[untold magnet]

uh, how am i going to detect when the player is left the world and give him a dynamic property?
playerLeave have only the playerId and playerName, i cannot give the player the dynamic property in that way..

[sharp elbow]

Can you use the PlayerLeave BeforeEvent?

I believe setting dynamic properties is supported within a read-only context. Correct me if I am wrong.

[unique acorn]

it wont work, I tried it before

[oak lynx]

[2025-03-23 18:36:09:456 ERROR] [Scripting] Unhandled promise rejection: ReferenceError: Native property setter [ItemStack::nameTag] does not have required privileges.

this has to be one of the stupidest things ever ngl

[unique acorn]

I remember Coddy said that it wont be an issue anymore in before events in 2.0.0

[ivory bough]

Maybe run a function outside of the playerLeave like make a function outside of it and then call it? Idk if it works

[untold magnet]

meh, i was trying to find a way to fix my titles issue without spamming the titles.

[dim tusk]

Uhh no? Using before events and setting dynamic property works

[unique acorn]

wait what

[dim tusk]

Yeah, dynamic property doesn't modify the world it's just scripts so the script doesn't throw the required privilege

always has been, since dynamic property was out it always worked like that.

[distant tulip]

that doesn't apply to all functions that dose not modify the world

[dim tusk]

but I'm only talking about dynamic property 🤷...

[distant tulip]

you linked it behavior to it not modifying the world... 🤷‍♂️

[dim tusk]

yeah, the before events and dynamic property works fine with me.

I didn't try it in .70 yet.

[distant tulip]

that is how dynamic property work from the start, .70 shouldn't be any different

[dim tusk]

I know...

[dim tusk]

That's why I said this too 😂

[distant tulip]

didn't read that tbh

[dim tusk]

-# my bad if it's a long video.

[rose light]

Is there any way to remove the item's durability when I use it, through CustomComponent?

[shut vessel]

Do you know what is wrong with it? There is no error message about it, but the commands are not executed as they should be.

[rose light]

I don't know why, but every now and then when I use the item, it doesn't remove the durability, but executes the command.

[coral ermine]

how to make subtitle visible without doing command for title?

[coral ermine]

/title @s subtitle

[unique acorn]

function giveItem(player, itemId, name) {
    let newItem = new ItemStack(itemId, 1);
    newItem.nameTag = `§r` + name;
    newItem.lockMode = "inventory";

    const playerContainer = player.getComponent('inventory')?.container;
    if (!playerContainer) return;
    playerContainer.addItem(newItem);
}

[coral ermine]

it won’t work with just title command?

[unique acorn]

you need json ui for that

[unique acorn]

const durability = item.getComponent("durability");
durability.damage = 0;

the higher the damage the lower the durability

[unique acorn]

@p cannot be used there

since there is no one running the command except for the dimension

which means there is no @p

[quiet oriole]

hello i want to make a hostile entity attack a player that the player receives in the entity and can't go down until something specific happens example a ghost hits the player and the player cannot be heard go down until the ghost dies or reaches a certain height, I wanted to know if someone can help me

[untold magnet]

uh, how am i going to detect the world difficulty?

[untold magnet]

nvm its beta..

[serene lava]

i downloaded a train addon that use scripts for rotating the wagons inmediately, when you spawn them, so i found this script, how can i make a script with that function?

[leaden elbow]

can ayone send sleep or wait function like sleep(ticks)

[wary edge]

Just use the built in system.waitTicks?

[dawn zealot]

        commands.forEach(command => {
            world.getDimension(`overworld`).runCommand(`execute as ${sender.name} at ${sender.name} run ${command}`);
        });
```anyone know why this shit just not working

[unique acorn]

idk maybe provide more of the code

make sure your min_engine_version is 1.20 or higher

[dawn zealot]

it is

is it because its in a beforeChat event

[unique acorn]

are you using system.run?

[dawn zealot]

no

[unique acorn]

then that's why

wrap the runCommand part in system.run

[dawn zealot]

oh yeah i gforgot that existed

i mean making u not losing thirst with the peaceful difficulty is not that necessary tbh

yeah, you could make your own entity
but that is the only way in stable currently

[terse pulsar]

I cant send the code

I hate that

I have some issues that i got on #debug-playground

I dont know how to solve

Here is the file

[valid ice]

Anyone know why glass is considered a "passable block" in raycasts?

[wary edge]

I do wonder if it considers it as non solid being passable.

[valid ice]

Then they should introduce a third filter for solid/non-solid and separate the two

[wary edge]

What is solid?

[valid ice]

Because by "passable" I assume "walkable by player" (vines, ladders, flowers, glow lichen, etc)

[wary edge]

Vsauce, Smokey here.

[valid ice]

However, it also includes leaves, scaffolding, slabs, cauldrons(!!), campfires, grindstones, lecterns, end portal frames, glass panes & glass in that category

[wary edge]

I wanna check the Java code again because i think my adk script lib references passable.

[valid ice]

added some things I just tested to the list

yikes 😬

[dim tusk]

iirc someone made a post in #1067535382285135923 saying includePassableBlocks doesn't work as intended.

[prisma shard]

await system.waitTicks(ticks)```

[leaden elbow]

i need help regarding setting preserved title text on all players. these values exist, its just only 1 title shows. i tried to use waitTicks but still showing the last setTitle but i want to show them all

system.runInterval(() => {
 function setTitle(title) {
   return world.getDimension("overworld").runCommand(`title @a title ${title}`)
 } 
  
   const active = db.getByIndex("quests", 0);

 setTitle(`qt:${active.name}`)
 setTitle(`qd:${active.type}`)
 setTitle(`qp:${active.progress}`)
})

[prisma shard]

what is the db class u used there db.getByIndex()

[leaden elbow]

its a customized db made by me

for arrays

[prisma shard]

one sec

[prisma shard]

system.runInterval(() => {
for (const player of world.getAllPlayers()) {

   const active = db.getByIndex("quests", 0);

 setTitle(player, active.name)
 setTitle(player, active.type)
 setTitle(player, active.progress)
} 
})

function setTitle(player, title) {
   return player.dimension.runCommandAsync(`title @a title ${title}`)
 }```

@leaden elbow

[leaden elbow]

let me try one sec

[prisma shard]

@leaden elbow

• so, first thing firrst, the function usage is like setTitle(player, title) but you used like "setTitle(qt:${active.name})" when you already used ${} in the function.
• why put function inside runInterval()
• consider using player.dimension instead of world.getDimension()

[dim tusk]

nvm

either way that's unnecessary

Why put in dimension if you still use title @a

Or use the player's dimensions itself

[distant tulip]

await system.waitTicks(ticks)```

[prisma shard]

oops

[prisma shard]

i just woke up so im blind lol

thx

[leaden elbow]

worked thanks

[distant tulip]

Same it is 4 in the morning

[prisma shard]

yw

[shut citrus]

how to save 1 block using structure manager?

[prisma shard]

why would you

[leaden elbow]

one last thing, can i only run it once instead of using interval? tried playerJoin but it doesnt show titles cus its still loading

[dim tusk]

Check if the player is moviny

There's no better way to check if the player is actually loaded, like see the blocks etc

[leaden elbow]

okok ill try this one instead thanks

also are javascript Set() supported in script api?

[dim tusk]

yes. new Set, Map, WeakMap

[lyric kestrel]

Ah I just realised I could use Set in a better system for my blocks if I ever want to improve it that horrendously more

[prisma shard]

coddy can you tell me what is the difference between using a Array and a Set

[dim tusk]

the first difference is that the array supports duplicate elements while the set doesn't. Second, set is faster than the array.

[prisma shard]

thanks!

[dim tusk]

i benchmark it before and doing Set.has() is faster than Array.includes() not noticeable in small cases but yeah

[dim tusk]

oh yeah another one is there's no indexing in set

like you do the [0] if you get what I meant.

[prisma shard]

oh

there's no way to?

[dim tusk]

you need to put it in array.

[prisma shard]

ah

[dim tusk]

const set = new Set([10, 20, 30]);
const array = [...set];
console.log(array[0]);```

ohh shiit

[slow walrus]

Array.includes iterates over each element until it finds the correct one.
Set is internally a Map where the key and value are the same, so has just tries to find the value associated with a key in a hashmap, which is much faster

pretty cool

[prisma shard]

yeah cool

[dim tusk]

You can also dojs const set = new Set([10, 20, 30]); const [first] = set; console.log(first);

[dim tusk]

yeah, that's why I mostly use set rn instead of array objects

[terse pulsar]

system.runInterval(() => {
    world.getAllPlayers().forEach((player) => {
        const chakra = player.getDynamicProperty('chakra')
        const chakraLimit = player.getDynamicProperty('chakraLimit')
        const dojutsuMode = player.getDynamicProperty('dojutsuMode')
        const cost = player.getDynamicProperty('cost')
        player.onScreenDisplay.setActionBar(`§e ${chakra}`)
        if (dojutsuMode !== 'none') {
            player.setDynamicProperty('chakra', chakra - cost)
        } else {
            if (chakra <= chakraLimit) {
                player.setDynamicProperty('chakra', chakra + 1)
            }
        }
    })
},20)

Why doesnt work?

[granite badger]

you just repeated what i did... would be great to get the error from content log

[terse pulsar]

Ok

[small cloak]

Dynamic properties are good, but I wish they had functions similar to Map's. You kind of need to make a wrapper to make them actually usable (Especially if you value performance).

Also not sure how I feel about string chunking. I feel like you're doing something wrong if you're storing that much data.

Something to also consider is that the dynamic property API can change in the future. Having a wrapper is good so you only need to update your code in one place instead of a million different places.

[lyric kestrel]

And a set can only hold 1 character per iteration

like Set("a", "b", "c"), etc

[stuck ibex]

What is there to change though? I feel like it's at it's peak

[small cloak]

There's just little things that are annoying. Like deleting a property shouldn't require setting it to undefined.

Checking if a property exists isn't straightforward too. Especially if the value can be falsy.

[slow walrus]

get !== undefined is hard?

[small cloak]

I never said it was hard. It just doesn't look good when you're reading the code. An explicitly named function that returns a boolean is better.

[slow walrus]

hmm, well that's what a wrapper is good for

[small cloak]

That's exactly my point. 😅

[slow walrus]

otherwise if you're checking if a value exists, then grabbing it, you're wasting an extra native call instead of just checking if the fetched value is undefined
