Script API General

[amber granite]

The length isn't a big deal

[distant gulch]

hmm okay

[amber granite]

for ( let i = 0 , i< array.length ; i++ )

[distant gulch]

so for veryyy big arrays

const arrayLength = myArray.length;

for (let index = 0; index < arrayLength; index++) {
  // ....
};

??

[amber granite]

Yep

Use forEcah for small arrays , because it s faster to write

And tge impact is very small

[distant gulch]

that's not a good argument

but when the perfomance doest decreases i would use more array methods

[amber granite]

If you're iterating over an array with 100,000 items, a traditional for loop is likely the fastest option. Here’s a quick comparison:

• For Loop: Most efficient in terms of performance.

  for (let i = 0; i < array.length; i++) {
      // process array[i]
  }
  

• forEach: More readable, but generally slower due to function overhead.

  array.forEach(item => {
      // process item
  });
  

• for...in: Not recommended for arrays; it iterates over all enumerable properties, which can lead to unexpected results.

For a large array, stick with the traditional for loop for better performance.

[distant gulch]

array.filter(...).map(...)

sometimes i use a loop instead of two array methods

[amber granite]

That s good too

Arrays methods are also slower

then the regular for loop

[distant gulch]

for (let i = 0; i < array.length; i++) {
    // process array[i]
};

isnt that very unperfomant?? every "run" it needs to get the array length again?

[amber granite]

U can put it in a variable

[sharp elbow]

Yea, you could store the array length into a variable and do the comparison against that

(can also do prefix increment in the loop update expression if you want to be fancy)

[amber granite]

U can also use
while loop

As u know the js isn't based on performance

If u want to control the performance use c++ or py or java

Because js is mainly used for site webs

So nobody really cares about the performance

[sharp elbow]

On the contrary, many of the web-focussed JavaScript engines work tirelessly to optimize how code is ran. And that is especially relevant to Minecraft too

[distant gulch]

hmm okay

[sharp elbow]

It may not be as fast as more traditionally machine-compiled code, but that does not mean people care not for how fast it can be

[amber granite]

If u want more performance for ur code

Clear the refrences for the variables or object that u won't use it anymore

To be collected by garbage collectors

If u have big Script and Database... Etc , use sorting algorithms

And those algorithms which will help the performance very well too

[fickle pulsar]

do yalls know how we can use other programming languages with js

[amber granite]

Or wait until Minecraft uses lua. instead of js

[amber granite]

Libraries

"jsons" files

Frameworks

[fickle pulsar]

ok

[amber granite]

It needs well programming knowledge

[fickle pulsar]

i can work on it

[amber granite]

But the easiest way to do it

Use jsons and node js

[fickle pulsar]

c++ classes are way easier for me to make

[amber granite]

What type of linking do u need ?

[fickle pulsar]

nah

i was just curious

[amber granite]

Ok

If u mean transpilers

Like turning js into c++ code

Or vice versa

[fickle pulsar]

ooo

if transpliers exist

it is possible to make a replica of the minecraft enviroment in c++

[valid ice]

¯_(ツ)_/¯

[dense skiff]

... if you asking this because you don't want to learn js, learning js would probably be easier than doing that for you

[sharp elbow]

These were the times I got from iterating over an array of 1,000,000. I tested each result ten times and averaged the result
Array.prototype.map: 262.5 ms
do..while loop: 224.1 ms
C-style for loop: 228.5 ms
Array.prototype.forEach: 217.9 ms
while loop: 206.6 ms
for..of loop: 205.2 ms

As anticipated, Array.prototype.map is not all that good, but someone should not be using that to iterate over an array anyway (unless they needed the results). for..of and while were better than the others, but only negligibly

In each loop, I was doing an assignment of i = i * i + Math.sqrt(i); (with i being the value at the index of the array) (I stole the idea from some random post I saw online)

[ancient sierra]

Hello! What's the latest version of @minecraft/server?

Thanks!

[fast lark]

I found out what causes it

world.beforeEvents.itemUse.subscribe(data => {
    let player = data.source
    if (data.itemStack.typeId == "minecraft:recovery_compass") system.run(() => main(player))

[fast lark]

wouldn't that be correct?

[sharp elbow]

Going off of the @minecraft/server npm page, the latest stable is 1.11.0, with the latest beta being 1.14.0-beta.

[ancient sierra]

I see, thanks again!

[amber granite]

The results may vary on each device

[sharp elbow]

They may. I tested this on Windows 11, v1.21.1.

help w/ what

[fast lark]

is dosent work for some reason

[amber granite]

The error

[prisma shard]

whats the error

show errro

error*

[fast lark]

wait

[amber granite]

Did u import

World ?

[fast lark]

yes

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

[amber granite]

What the error that got logged

[amber granite]

In console

It s syntax error

If u got SyntaxError that means u didn't close paranthes

Or curly braces

[fast lark]

it issss

[fast lark]

?

[prisma shard]

Is this the code

?

Wait i will fix

[amber granite]

U must add }) in the end of the code

[prisma shard]

I know

[fast lark]

wait

.-.

[prisma shard]

[amber granite]

Do u use IDE ?

[fast lark]

I tried to do it again and it worked

[amber granite]

When someone asks for help here everybody rush to help XD

[prisma shard]

xd

[amber granite]

That s funny

[fast lark]

xd

[shy leaf]

reminds me of someone

[prisma shard]

Of what?

[shy leaf]

a guy

[prisma shard]

a guy, but who

[fast lark]

a guy

[shy leaf]

who made their code with like

[prisma shard]

with like?

with what?

[shy leaf]

fuckleton of if else

[prisma shard]

☠️

bruh

[shy leaf]

• making every single model bones

animated

with code

[prisma shard]

☠️

I am choking

[solar dagger]

Has anyone made a hunger meter for items?

[odd sky]

I don't suppose someone knows why this is failing

[cinder shadow]

where's the code?

Is it in a loop that adds several enchantments at once?

[odd sky]

enchantable.addEnchantment({ type: EnchantmentTypes.get('piercing'), level: 1 })

[odd sky]

Yes

[cinder shadow]

The enchantment errors outputs are terrible

you're trying to add an enchantment to something that can't accept the enchantment

It already has another enchantment in the same group that 'piercing' is in

I think that was the issue, at least

[odd sky]

That's odd considering I'm checking if it can be added enchantable.canAddEnchantment()

[cinder shadow]

I think that might be what's throwing the error tbh

[odd sky]

I do have multishot also being added, forgot those were incompatible. Going to remove that and check

Yeah that solved it

Thanks

[cinder shadow]

I think .canAddEnchantment also works by adding it to the itemStack to see if it's valid, then removing it. Which would just error it out.

[neat hound]

Can also be if it has that enchantment and you add same, maybe it would take the level higher than can be. Can that checking thing check for that, do you give it the proposed enchantment with level?

[odd sky]

Yeah it's given it with the level

And I don't have piercing being added anywhere else

[thorn ocean]

There is no way to have constantly updating server forms, correct?

[somber onyx]

    export function getInv(player) {
        let inv = []
        for (let i = 0; i < 36; i++) {
            let container = player.getComponent("minecraft:inventory").container
            inv.push(container.getItem(i) ?? { typeId: "§cAir", amount: 0})
        }
        let form = new ActionFormData()
        .title("§9Mon Inv")
        .body("")
        inv.forEach(it => {
            form.button(`§u${it.typeId.replace('minecraft:',"").replace("_"," ")}`)
        })
        form.show(player)
    }

I was given this function but I do not know how to get the quantity of an item present in a slot despite the fact that I understand the function

someone would help me

[odd sky]

You'd have to close and open a new form

[fading sand]

how do i replace the item in my offhand with an item that canot be moved and is slot locked?

i forgot

[thorn ocean]

And one would have to do that manually, right?

[odd sky]

Yes

[fading sand]

if (offhandItemStack.typeId.endsWith('_off')) {
        let item = offhandItemStack.typeId.replace('_off', '')
        let itemLocking = item.lockMode = "locked";
        source.getComponent('equippable').setEquipment('Offhand', itemName)
    }

would this replace the item named _off at the end with an item that is locked and is not th off named item?

[amber granite]

What ?

[solar dagger]

world.afterEvents.playerInteractWithEntity.subscribe(({ player, target }) => {
  const ridingComp = player.getComponent('minecraft:riding');
  if (ridingComp && target.typeId === 'fs:mammoth') {
    const mount = ridingComp.entityRidingOn.typeId;
    if (mount === target.typeId) {
      if (target.getComponent('minecraft:is_saddled')) {
        itemTransfer(player, target);
      } else {
        console.error('Target does not have a saddle');
      }
    } else {
      console.error('Target entity does not match the entity player is riding');
    }
  } else {
    console.error('Player is not riding an entity');
  }
});```

Could it be because the itemStack is undefined?

i basicaly want to do a item switcher

[amber granite]

Oh

[amber granite]

Because playerInte , is in beta api only

[solar dagger]

Im aware...

[fading sand]

is it correct?

[amber granite]

playerInteractWithEntity is the undefined

@solar dagger

[amber granite]

What the error that appears?

[amber granite]

Are u sure ur using beta api ? @solar dagger

I don't think so

Send me the manifest

And turn all experimentals

[fading sand]

havent tested yet

[amber granite]

Test it then

But

Why did u use async @fading sand ?

[fading sand]

doesnt it go instant than? mightve missed smth

[solar dagger]

i fixed it nvm

[amber granite]

Don't use async

[fading sand]

why?

[amber granite]

It s not useful in this situation

[fading sand]

alr

ill remove than

[amber granite]

Because it will make

Ur code slower to excute

[fading sand]

ahh

atm i have one error by the way

let item = offhandItemStack.typeId.replace('_off', '')
let itemLocking = item.lockMode = "slot";

seems like item isnt an object or smth

@amber granite

maybe i need to set it first

[valid ice]

Just do item.lockMode

[fading sand]

or do newItemStack thingy

[valid ice]

Don’t set it to a variable

Can’t do the double equals like that there

[fading sand]

oh ok

wait

but for that i would need to do an new item stack right?

[valid ice]

No

[fading sand]

oh ok, leme try than

[valid ice]

Oh I see what’s going on

You’re setting item variable to a string. A string does not have the lockMode property.

[fading sand]

oh, so what do i need to do in order to fix it?

[valid ice]

And itemName would be undefined, as it doesn’t exist in the code you sent

[fading sand]

oh

so what do i do now?

how can i make it not be a string but item

[valid ice]

Idk what you’re wanting to do

[amber granite]

? Elaborate

[fading sand]

i wana do an item switcher

[fading sand]

like atm its not working cuz the item variable is an string

[amber granite]

Create new stack

Then set it to players hand

[fading sand]

ahh, i knew it

[amber granite]

Because

They are different items

[fading sand]

let item = new ItemStack(offhandItemStack.typeId.replace('_off', ''), 1);
        item.lockMode = "slot";
        source.getComponent('equippable').setEquipment('Offhand', item)

[amber granite]

Yes

But what id item.lockMode ?

It s a string

Not an object

To make a proprety to it @fading sand

[fading sand]

?? I thought its an item stack now

[fading sand]

how?

[amber granite]

Yype id = string

They are the same thing

[fading sand]

yes, but item stack

[distant gulch]

Hello

[fading sand]

like it becomes an item stack

hi

[amber granite]

Not

No it a type i

Id

That s not how js works

Xd

[distant gulch]

I want to make a Database with DynamicProperties, should i add a chache where the gotten data gets stored?

[fading sand]

so what do i do now?

wait

[amber granite]

Yeah i made that

[distant gulch]

With new Map() or Array

[fading sand]

type id is without id right?

wait it isnt

im dumb rn

[amber granite]

I can't explain it frnow u don't have the required knowledge

[distant gulch]

I can help too!

And i need help too

[amber granite]

Wait...

[fading sand]

but people do it like this:
new ItemStack('minecraft:iron_sword', 1);
im confused..

[amber granite]

I don't know if u can add costimzed proprety

On itemStack

[valid ice]

Item dynamic properties

[amber granite]

Yes that s better

[fading sand]

so what do i need to use than

to set an locked item with an certain name

[amber granite]

item.setDynamicProp

[fading sand]

and item is the string?

[wary edge]

New itemstack
Item.lockmode
Item. Blah blah
SetItem(item)

[fading sand]

but thats what i did

[wary edge]

Did it work?

[distant gulch]

Object.defineProperty(ItemStack, 'key', {
    enumerable: true,
    writable: true,
    set: (v) => {},
    get: () => {} 
})

maybe with that

[fading sand]

let item = new ItemStack("${offhandItemStack.typeId}_off", 1);
        item.lockMode = "none";
        source.getComponent('equippable').setEquipment('Offhand', item)```
no

[amber granite]

I can't focus °-°

[fading sand]

wait

nvm

it did work

[wary edge]

Are you doing this in a before or after event?

[distant gulch]

Guys, when i want to make a cache with key and value, should i use the Map class

[amber granite]

Yes

Cache use map

[distant gulch]

okay good

[amber granite]

But

[distant gulch]

yes

[fading sand]

after event

[amber granite]

What are trying to do

[distant gulch]

A DataBase and i want to put the gotten datas in a cache

[amber granite]

Oh

What s the type of data ?

[distant gulch]

Key and Value ( value as string and normal )

[amber granite]

What about

Using a variable

[amber granite]

Is it deep object data ?

Or just shallow one

[distant gulch]

const data = {
    key: string|number|boolean,
    value: {
        encoded: any, 
        decoded: string
    }
};

deep i would say

[amber granite]

U can stringify it

And put it as string in the world dynamic proprety

[distant gulch]

yes i want to do it like that

[amber granite]

And whenever u use parse the object

That will be better

[distant gulch]

i remeber now, i dont need encoded or decoded

[amber granite]

Yeah just use :
JSON.stringify

And put the loaded data in a variable

[distant gulch]

yes i know the method

[amber granite]

And that s it

And whenever u need the data parse it

[distant gulch]

but i just want to know, should i cache all the gotten data

[amber granite]

If the data is big!!

[distant gulch]

sometimes

[amber granite]

U know that cache is used for calculations after big process

That give u static return

Instead of recalculating it every time

So i don't think u need cache

Just use a string

And put it in a variable

[distant gulch]

i think you are missunderstanding me

[amber granite]

U are talking about loaded data right?

[distant gulch]

Yes, i mean when my databases like gets initialized, should i get from the start all the datas and store them, so i can get them directly from the storage or should i always get them by getDynamicProperty

[amber granite]

U means

Getting them from ram or rom

Because getDynamicPropreties uses rom and it s slower

[distant gulch]

Hmm okay

[amber granite]

And making it into a variable = cache it in ram

U need to Making it in a Variable if u want real fast result

[distant gulch]

what do you mean by variable, a map? like

const cache = new Map();

[amber granite]

No just a regular variable

I told u u need to stringify it

[distant gulch]

how should i be able to storage all the datas form the database in one variable

[amber granite]

'/"the stringified object"/"the next one"/'

[distant gulch]

yes but i dont save small datas

i want to save to like 500 objects

[amber granite]

The variable handles the big objects

How can i explain it to u

I m dumb in that

[distant gulch]

same

[amber granite]

But making the object as string is better for ur ram

Instead of using map

Because that will takes a lot of ram

[distant gulch]

I can't just save a huge stringified aobject with about 32K chars in one var and everytime i want to get a value i need to parse that

[amber granite]

And if u want to get an object u can just search in that string

[hazy nebula]

How to repair item with script 🤔

[amber granite]

And get the object and parse it

[distant gulch]

imagine parsing a 32k chars string

[amber granite]

U can because it s ram friendly

[amber granite]

No

[wary edge]

Get the durability component

[amber granite]

I mean search for ur object

[hazy nebula]

I dont know can u help me code

[distant gulch]

btw is DynamicProperty always better than scoreboard?

[amber granite]

The objects = " object1.{jej : 772 } / object2.{uehe:827} / "

And there is built in method in string

That let u get the object by name

And slice the part of that object

Then parse it

[distant gulch]

imagine the objects haves a key what haves the same name as the key i want to get

[amber granite]

For that u gonna get the object by name

I just used that method in my database

And it worked

[distant gulch]

isnt it a really slow mthod?

[amber granite]

But ram friendly

And not that slow

Because the variable itself is saved in ram

And the objects are small

[distant gulch]

when i need to get fast datas, and i hav elike 500 objects in there

[amber granite]

Yeah normal too

[distant gulch]

i have maybe less than 500 chars per object

[amber granite]

Same bro

[distant gulch]

hmmmm

[amber granite]

If u want map u can used it

Tho

Just put the object name

In the key

[distant gulch]

what exactly is ROM?

i only know RAM

[amber granite]

So

[distant gulch]

yes

[amber granite]

It s the hard drive

[distant gulch]

okay

[amber granite]

That s all XD

[distant gulch]

idk if my laptop evens haves a HD

[amber granite]

Hdd

Exactly

[distant gulch]

i have an SSD storage

[amber granite]

Same

The ram is faster then them

[distant gulch]

Okay, i dont think my Laptop haves a Hard Drive Disk because i use a SSD

[amber granite]

The hard drive is only to store things that the system won't use them

[distant gulch]

hmm okay

its build in the mainbaord?

mainboard*

[amber granite]

Yes and no

The rom ?

[distant gulch]

yes

[amber granite]

Yes and no

[distant gulch]

okay

[fading sand]

if i have an item that only has one tag, can i do this to get it?:
let tags = itemStack.getTags();?
or do i still need to get the full array

[amber granite]

The ssd are on the main board

And hdd are not

[distant gulch]

you still get an array with strings, or an empty one

[distant gulch]

okay

[fading sand]

.2 ssd

[amber granite]

Just the Ram is faster

Then the fastest the rom

[distant gulch]

I have one SSD from Samsung build in

[amber granite]

That what u need to know

[distant gulch]

okay nice

[amber granite]

Ur images and files

Get saved in the rom

[distant gulch]

Are you german?

[amber granite]

No

[fading sand]

ah ok, so i would need to do tags[0] to get it?

[distant gulch]

Yes

[fading sand]

alr thx

[amber granite]

So if the data was saved in ram

[distant gulch]

RAM = Random Access Memory

ROM = ???

[fading sand]

cd rom

[distant gulch]

it takes longer to get or execute the data?

[amber granite]

Read only memory , or the dead memory

In some languages

[amber granite]

It takes a small time idk like 1 second , to get the data

But not a big time

[distant gulch]

so the map Class saves the datas in the RAM?

[amber granite]

It s something linked to ur data size

[amber granite]

Yep

U can use it immediately

[distant gulch]

So that means, Objects are saved in the RAM and variables in the ROM =

[amber granite]

No

Variables are saved in ram too

Until ur serialize them

[distant gulch]

serialize?

[amber granite]

Yep

[distant gulch]

what does that mean exactly?

never heard of it

or my English limits found their end

[amber granite]

I must explain the computer science for u XD

[distant gulch]

sad

[amber granite]

So u know the data in ur script

Get deleted

After u just exit the world

Because it s saved in ram

[distant gulch]

Yes

[amber granite]

But not in devices storage

[distant gulch]

okay

[amber granite]

So u need a process named serialisation

That write that data in ur ROM

[distant gulch]

okay but why

[amber granite]

What u mean by why ?

[distant gulch]

why should it write the data in ROM after deleting it in the RAM

[amber granite]

U doing that by making a db u silly XD

[distant gulch]

okay okay

[amber granite]

U kbow why dynamic propreties used for ?

Or no ?

[distant gulch]

not really

[amber granite]

So let s say

U want to save players items from the world start

[distant gulch]

Yes

[amber granite]

Until the time he exist the world forever

The script can't do that without access to Rom

The storage in ur device

[distant gulch]

ii dont understand that sentence?

[amber granite]

Ahhh

Let s say u want to save players death times

[distant gulch]

Sorrry either ist my english or your grammar

[amber granite]

Using script

[distant gulch]

Yes

[amber granite]

U can't do that with only script

Without saving the times that he died

Because u know the script is excuted in ram

[distant gulch]

yes, we need to likke storage his deaths somewhere

[amber granite]

Yep

That somewhere called ur ROM

[distant gulch]

really? cool

[amber granite]

Or storage

[amber granite]

Everything works in ram

Because rom is so slow

And the device processor

Need something to save data in

His runTime data

Because that ram is more expensive then rom

[distant gulch]

yes, 64gb ddr4 ram costs about 100€

[amber granite]

As examples u find ram with 6 gb is expensive then rom with 200 gb

[distant gulch]

1TB ROM = less than 70€
64GB RAM = less than 120€

[amber granite]

That s how computer's work

[amber granite]

Yes

So u know the processure

I5 - intel

Or idk

[distant gulch]

thats why saving takes longer than the other shi*

[amber granite]

I7 - 10 th

[amber granite]

Yes

[distant gulch]

i dont really know inter proccessors

i have an AMD ryzen

[amber granite]

Yes

The amd Ryzen u use

Called processor

[distant gulch]

Yes

[amber granite]

The processor needs a storage to save the data he proceeded in it

And here comes the ram

Without ram nothing in ur device will work

Because it s crazy fast

[distant gulch]

okay nice, btw lets continue it in dm, i need to go really fast rn

[amber granite]

Same as processor calculating speed

Ok

[solar dagger]

would i have to run an interval/job to check whether the player is riding a certain entity? or is there a event that i can use to help detect this?
@wary edge

[distant gulch]

Sorry, be right back

[amber granite]

Ok np

@amber granite

[amber granite]

I don't know

[distant gulch]

backkk

[amber granite]

Hey sorry

There some misunderstood in my messages

Rom is other type of data storage

U can't change it ever

[distant gulch]

hmm okay

[amber granite]

It used for system level

Things like bios

Etc...

[distant gulch]

okay, so read-only

[amber granite]

So i mean by rom = hdd or ssd

Because they are writable

[distant gulch]

okay

[amber granite]

Not like the rom which us soliderated into the mother borad itself

[distant gulch]

okay

[amber granite]

So , u need to get data from the hdd and ssd

And write in it

[distant gulch]

okay

[amber granite]

And ram is faster for that specific thing

[distant gulch]

and codes gets executen or saved in the ROM

RAM*

[amber granite]

No

In ssd

And hdd

[distant gulch]

okay so in ROM?

[amber granite]

Rom is other thing

[distant gulch]

read only thingy right

[amber granite]

I told u it misunderstood from me

[amber granite]

Yep

I mean by rom is hdd and ssd in the last speach

Because rom is something other..

[distant gulch]

so in HDD or SDD gets the code saved or executen?

[amber granite]

Yep get saved in

[wary edge]

What is this converstaion?

[amber granite]

About saving datas

[distant gulch]

main theme was a database

and the variable i have, lets call it rawCache

it gets saved in the HDD / SSD ?

[amber granite]

Yep it s saved in ram

[distant gulch]

okay ram

[amber granite]

The ram saves everything that cpu working with

[distant gulch]

Because its faster

[amber granite]

From getting data to setting data from and to it

[amber granite]

Yes faster then rom and hdd and ssd

Because that it s expensive

[distant gulch]

yes
more efficiency > more expensive

[amber granite]

Yep

So .,

U code get excuted in ram

And all data associated with it

Got saved in ram

Until u exit the code

Then everything cleared

It s like humans short memory

[distant gulch]

Yes, but the code im having rn is either saved in the RAM when i didnt saved the code yet and when i save dit, its saved in the HDD / SSD?

[amber granite]

Yep

[distant gulch]

okay

[amber granite]

I mean only the essential data

Like objects

Etc...

I mean not the whole code

[distant gulch]

okay

[amber granite]

I mean only what u want to save and get it for later

[distant gulch]

okay

[amber granite]

So i told u to make a variable

And put strings of objects in it

Because it saved in ram

[distant gulch]

But a Map class is also saved their

[amber granite]

Yep

But hold more data

[distant gulch]

and it stakes longer thhe get single datas?

takes*

[amber granite]

No

I mean Map allocate as examples : 32 mb

As example

In RAM

But when u use a string instead

[distant gulch]

an empty one?

[amber granite]

No just an example

[distant gulch]

Okay

[amber granite]

It takes more lower then that

[distant gulch]

Okay because they are two arrays that are being saved or what?

[amber granite]

Two arrays ?

[distant gulch]

Ive seen the class Map works with two array

Key and Value array

[amber granite]

Oh

Yes

So u know js object

It doesn't saved types

[distant gulch]

What do you mean?

[amber granite]

I mean if u assigned proprety:

[distant gulch]

The JS object like [] or {}

[amber granite]

object = {}
object.true = 1
Is same as
object["true"] = 1 

[amber granite]

Like {}

[distant gulch]

okay this object

[amber granite]

Yep

It has somethings called keys and values

[distant gulch]

yes, properties ad values

[amber granite]

So keys returned all to one type is string

U can't put boolean

Or number

Or null

Or idk

It all like
Let boolean = "true"

But not a real boolean type

[distant gulch]

okay so types wont be saved, they are ending up as a string?

[amber granite]

Yep

The "Keys"

Not the values

[distant gulch]

okay, plus point to arrays

yes iknow

[amber granite]

the arrays

Not a big deal

It just like

Putting two arrays in an object

Won't make a real thing

But see here

When using map

Let map = new Map()

[distant gulch]

yes

[amber granite]

map.set(true , 5);
map.set("true" , 5 )

[distant gulch]

will the first key be overwrited by the second one?

[amber granite]

No

They are separated

If u type

[distant gulch]

because of different types

[amber granite]

Yep

[distant gulch]

good

[amber granite]

That u can't do with regular object

There is another feature also

For maps

[distant gulch]

that's?

[amber granite]

U can put an object as key

[distant gulch]

wasnt it used for WeakMap??

[amber granite]

No

[distant gulch]

hmm okay

[amber granite]

Weak map are for something called refrence

[distant gulch]

okay okay

When i save something in map by using ann object as the key

i do need to have the same object as before to get it again?

[amber granite]

Sorry net get cutted off

For a min

[distant gulch]

No problem

[amber granite]

Yes

So u see

Lemme give u example

[distant gulch]

okay but how does the code knows, if object1 === object

[amber granite]

In Map ?

[distant gulch]

yes

[amber granite]

That s good question

[distant gulch]

i have read that you can't just compare objects like obj1 === obj2

[amber granite]

But i can respond it fn

[distant gulch]

no problem

[amber granite]

• comparing objects is not like that

[distant gulch]

maybe by stringifying that object

[amber granite]

Ahhh

U know

Different objects

[distant gulch]

yes?

[amber granite]

Means they don't have the same propreties

[distant gulch]

yes, kinda

[amber granite]

If u put the same propreties u will get the same result

Even if u have individual ones

[distant gulch]

hmm

[amber granite]

Because in object situation

U need different object structure or names

Etc...

[distant gulch]

to identify them correctly?

[amber granite]

Yep

U can't as examples

Let object1 = { id : 3 }
let object2 = {id : 3 }

And put them in a map

As this

map.set( object1 , true )
map.set( object 2 , false )

U will get only false

[distant gulch]

because it overwrites it?

[amber granite]

Yep

So what didn't u understand fornow?

[distant gulch]

hmm, they save the objects, datas in RAM right?

[amber granite]

Yep

[distant gulch]

and they must be founden by an id right?

[amber granite]

Yep

[distant gulch]

every variable haves a different one

[amber granite]

What do u mean by id ?

If id in the first one was = true

[distant gulch]

i mean if the codes needs like variable2, it needs to get them by an id or not?

[amber granite]

Elaborate

[distant gulch]

it can't just say

this is variable_2
23193981298312333129383290233

[amber granite]

Yes

[distant gulch]

it must declear it for the pc so the pc can get it in the RAM

declare*

or identify

[amber granite]

Yep

I didn't understand XD

[distant gulch]

variables are getting saved in the RAM

[amber granite]

Yep

[distant gulch]

and somehow the script or pc needs to get them from the RAM when its needed

[amber granite]

Yep

But ram is fast

And the js engine is optimised

So u can't feel that

[distant gulch]

but the script can't just say, this 139328328127371224847124 value in the RAM was from the variable, it needs to mark it somehow as variable_2 with an id or somewhat like that

[amber granite]

Yep

[distant gulch]

so every variable is marked with something like an id

[amber granite]

Yep

Ofc

[distant gulch]

so js could easy do like

obj === obj // true, same identifier

[amber granite]

Yep and no

Obj === obj

Is not what u think

It s based on something called refrence

U need a function to compare objects

And libraries

But yes

[distant gulch]

but didnt you said like:

const obj_1 = { id: 3 };
const obj_2 = { id: 3 };

const myMap = new Map();

myMap.set(obj_1, true);
myMap.set(obj_2, false);

myMap.get(obj_1);; // would it be true or false

[amber granite]

Yeah but fhe value

[distant gulch]

does the object gets stringified there?

[amber granite]

I don't know the rxactly method

But u can say that

[distant gulch]

hmm okay that's why the value would be false

[amber granite]

Wait a min

[distant gulch]

Sure

[amber granite]

Can u wait ?

Yeah

As u said ur true

I just forgot about the refrences

@distant gulch

[distant gulch]

Hmm?

[amber granite]

Ur true

[distant gulch]

about what?

that the value would be false

[amber granite]

No will be true

[distant gulch]

huh

[amber granite]

Because those objects are in variable

[distant gulch]

yes

[amber granite]

If not in variable

U will get false

[distant gulch]

Hmm because by variable, it haves a lke different identifier=

[amber granite]

Ffff

[distant gulch]

sad

[amber granite]

No ur true

Even without variables

Two objects are not the same

const myMap = new Map();

myMap.set({ name: 'Alice' }, 'Value for Alice 1');
myMap.set({ name: 'Alice' }, 'Value for Alice 2');

console.log(myMap.size); // Output: 2

[distant gulch]

hmmm

[amber granite]

It s complex i know

[distant gulch]

when i would use two different variables, it would be still 2 ?

[amber granite]

Yes

But

If u tried like

map.get({name: 'alice'})

U will get the second value

Value for alice 2

[distant gulch]

huh

but hoow can i get the first one

[amber granite]

Wait

[distant gulch]

sure

[amber granite]

XD , i hate maps

U will get undefined

[distant gulch]

i love them

huh

[neat hound]

This is where taking the JS basics come in handy.... objects are not data, they are pointers to an address that hold the data, that is why they are not equal.. my house is not your house. You have to use other methods to compare the innards of objects... and arrays are objects too.

[amber granite]

^

[distant gulch]

Alright, Thanks Niki

Nikki*

[amber granite]

U must learn something called refrence

It will be very handy

[distant gulch]

they are just saying like, the data is there

[distant gulch]

okay

[amber granite]

Yes

But u can't get it

Because u like ,

Putted new object in it

It s different from the last two ones two

[distant gulch]

yes because the like "pointer" arent the same

[amber granite]

But u can get the data

Using forIn loop

[neat hound]

I like this group of people.... they explain well and give you a space to practice. https://www.geeksforgeeks.org/javascript/

[valid ice]

Stringify each and compare if you wish.

[amber granite]

That s for quick compare

[distant gulch]

thanks but i can't watch videos cause my wifi is hell right now

[neat hound]

no videos

[distant gulch]

ohh then good

[amber granite]

I have good source two

I learnt from it

If u want

[neat hound]

well, I mean they have some, but not for classes of this...

[distant gulch]

i used SoloLearn and w3schools

[amber granite]

https://javascript.info/

[neat hound]

I did not learn from them, but they are my reference when I forget or need another way to do something. They give as many ways as possible

[distant gulch]

Nice, and btw

[amber granite]

U can learn from that , there is gitHub version too , offline

[distant gulch]

DynamicProperties are being saved in the HDD/SDD right?

[amber granite]

In world UID

But yes the world UID is getting saved

In hhd and ssd

[neat hound]

to the world, wherever it is... so if a realm, to the realm

[amber granite]

Same thing

[neat hound]

if on your PC, then your PC with the world

[distant gulch]

bombing the realms storage yeah

okay as i thought, so i could just use getDynamic.... permamently to get datas, but that would be slow right?

[neat hound]

they limit what you can store.... string, number, boolean, vector3... that is it

[amber granite]

Yep ofc

[neat hound]

the other database thing is different.. no exp with that yet

[distant gulch]

The maximum char limit was 32767 right? or was it the maximum amount of Bytes

[amber granite]

Yep

Length or byte

[valid ice]

Dynamic properties are only slow in the sense that they are script API methods and not vanilla JavaScript

All things considered they’re decently fast.

[distant gulch]

but isnt the Minecraft API build in Minecraft?

[valid ice]

It’s based off of quick js

[distant gulch]

and quick js is just js but in faster?

[valid ice]

It’s one of many available engines for JavaScript

[hardy tusk]

The fact native apis are slower than an emulated language 😭

[amber granite]

Js without some js vanilla things

[rugged tinsel]

they're not, it's the translation between js and c++ that's slow

[distant gulch]

okay okay

[hardy tusk]

I know

[distant gulch]

they just removed eval sad

[rugged tinsel]

that's just how these things work

can't really get around it

[hardy tusk]

But thats on them

[amber granite]

U won't use it tho

[valid ice]

Eval exists, you just need a manifest thing

[hardy tusk]

Yes, better engine

[distant gulch]

same, never needed it

[distant gulch]

🙂

[rugged tinsel]

I agree that they picked a bad engine, but with the engine they have, there's no way around it right now

[hardy tusk]

Node is much faster if you use native api's, and apis from c++ node packages, because it aint suck

[rugged tinsel]

though honestly, the engine's not that bad performance-wise when you're only doing js stuff, it's once you start calling APIs that it starts to die

[hardy tusk]

It goes to show how good it can actually be

[rugged tinsel]

not a fair comparison

NodeJS gets to use JIT and such

[distant gulch]

const cachedString // "<keyName>:<pointer_to_index_in_data>"
const values // "datas, datas..."

could i save it like that

[hardy tusk]

Yeah but that doesnt have any impact on API calls

[distant gulch]

cachedString contains the keys and the "pointer" or "adress" to get the datas

[rugged tinsel]

it probably has an impact to some degree

haven't researched the topic, but that's just my guess

[hardy tusk]

unlikely, maybe very small impact

[amber granite]

But when data gets bigger and bigger

They will be slow asf

[hardy tusk]

Insignificant enough to not play a role in the argument

[distant gulch]

uhm kiroo

[amber granite]

?

The net get cutted off again

[valid ice]

Dynamic properties have a limit for a reason

[distant gulch]

Can i do it like that Kiro?

const cachedString // "<keyName>:<data_address>"
const values // "datas, data..."

[neat hound]

yeah... cause of yall.... LOL

[hardy tusk]

Well you can always just use js to do it for you, and save it with dynamic properties every now and then

[distant gulch]

32767 Chars or Bytes?

[valid ice]

Chars

[rugged tinsel]

did they ever address their reasoning for choosing quickjs? I can't recall

[distant gulch]

good

[amber granite]

In ur db ?

[distant gulch]

yes

[amber granite]

Use let

[hardy tusk]

I think they said because its easy to implement and get working

[amber granite]

Because cachedstring get changed

[distant gulch]

Right right

[amber granite]

EveryTime u loded again

[distant gulch]

does people exists who* are using var ?

[amber granite]

Wh ?

[distant gulch]

let gets reloaded to?

who*

[amber granite]

I didn't understand, can u reask again

[distant gulch]

Does People exists, who are using the var syntax? instead of const or let

[amber granite]

Oh var used for js in the olds times

But no one use it for now

[valid ice]

I’m sure folks use it nowadays

[amber granite]

Except somethings

[distant gulch]

let and const where from ES6 right?

[amber granite]

Maybe

But u can make usage of it too

[distant gulch]

you said

> Use let

> Because cachedstring get changed

> EveryTime u loded again

but let gets also cleared ?

[valid ice]

People do goofy stuff with their code. var is like, one of the less weird things.

[amber granite]

Like getting variable out of block scopr

[amber granite]

Yes

[distant gulch]

okay good

[amber granite]

Const var ,
Is something will get error

Every time u try to load new data

Into ur string

Because const is for static variable

[distant gulch]

right, because const must be declared

[amber granite]

Like PI

Yeah

Another question?

[distant gulch]

Hmm let me think

i guess i bothered you enough

[amber granite]

No

I love helping ppl

[distant gulch]

Nice

[amber granite]

What ☠️

[distant gulch]

Okay then

nothing

[amber granite]

Yeah so

[distant gulch]

never said anything

[amber granite]

Don't use maps because u won't need them as I KNOW

[distant gulch]

okay

and they are using too much of my RAM

[amber granite]

Yep

[distant gulch]

i got some threshhold warnings with my last database

> 16 MB or something like that

[amber granite]

☠️

Ram or Storage?

[distant gulch]

i was using Map

[amber granite]

Oh

Yes

[distant gulch]

so Ram

[amber granite]

For that u need string instead

[distant gulch]

yes ill try it to make

[amber granite]

Because it s ram friendly

If u got another problem

Tell me

When making ur db

[distant gulch]

ill save datas like that

world.setDynamicProperty(`[${databaseId}]${key}`, DATA_STRING)

[amber granite]

Good

[distant gulch]

and getting them like

cache += key:address
values += DATA_STRING

[amber granite]

Wait

[distant gulch]

yes

[amber granite]

What is jey:address ?

[distant gulch]

jey?

[amber granite]

Key

[hardy tusk]

Switch statements...

https://tenor.com/view/patrick-patrick-star-patrick-stare-patrick-eyes-red-eyes-gif-14781443

[distant gulch]

its the key and the address, address contains the start and end index in values from the value i will stringify

[distant gulch]

i actually use them

[amber granite]

Ahh

Use Stringifiy

[distant gulch]

maybe ill ad the type of the value, so i can make it more precise

[amber granite]

Stringify the object

[amber granite]

Ahhh

Do u mean the value in the object? Property?

[distant gulch]

// keyName:(0,23,string)...
// values: "\"this is a string",2,12,...."

[amber granite]

Oh noo

[distant gulch]

?

[amber granite]

Not that way

[distant gulch]

okay?

[amber granite]

That will kill ur pc

[distant gulch]

this isnt a object btw

[amber granite]

What u gonna save ?

[distant gulch]

that are two string, wait

[amber granite]

So u will saves keys on a string

And the values on another string

Then what !!!

[hardy tusk]

Yes the was more about how, when you're in a switch statement, you cannot do something like

switch(arg[0]) {
case "kick":
let player = getPlayer(arg[1])
player.kick()
break;
case "invite":
let player = getPlayer(arg[1])
sender.invite(player)
break;
}

This wouldnt work

And its horrible

You would have to use var, or wrap all the entries in the switch statement in {} brackets who use that variable name

[amber granite]

What about putting
Arg[0] value on a variable

[distant gulch]

my eyes

[amber granite]

Way. , My bad

[distant gulch]

@amber granite

// key : ( startIndex, length, type )
let addresses = "PI:(0,5,number),PI2,(6,5,number),A_STRING(12,8,string)"
// value,value,value...
let values = "3.141,6.282,a string"

[hardy tusk]

And this is because when you are in a switch statement, it considers all case's to be on the same level, because technically 2 case could execute after another

[distant gulch]

like that

[amber granite]

What da

[distant gulch]

sad

I will be right back, crying on toilet

[amber granite]

What da

I m shocked

[hardy tusk]

Which is honestly really stupid, because the only time this would make sense is when you have a variable declared in a case and then want the switch to match the 2nd case you could use that variable in the 2nd case, but that is A TERRIBLE practice and should never be done and you can also just declare the variable outside the switch and assign an value to it, so the entire idea of this is completely useless

[distant gulch]

im back

[amber granite]

Bro just stringify ur object

[hardy tusk]

Im on phone, not gonna do indentation lol

[distant gulch]

okay

[distant gulch]

but i wasnt saving an object

[amber granite]

U was saving propreties?

[distant gulch]

that are single example values i saved like a number, another number and a string

[amber granite]

Hmm , ok

[distant gulch]

and they just added to the strings

the addresses and values

[amber granite]

Yes then ?

[distant gulch]

And i can't use JSON.stringify on a number so i added the type of the value so i can use the right function to get the value of it

[amber granite]

Bro

Json stringfy is only for object

Even if proprety was a number

Or true or false

It just takes the object and put two qoutes

On every key and value on it

And when u parse it

U will get the object again

As it was

[distant gulch]

wait a sec

[amber granite]

XD bro choses to think harder and work dumber

[distant gulch]

lol i didnt knowed that json.parse can even parse simple string values lol

[amber granite]

👀

[distant gulch]

i tought it only were for Objects

[amber granite]

Yeah for objects

Try this

[distant gulch]

ive tested it rn

[amber granite]

{ id : 5 , pd : true , is : "jeje" }

[distant gulch]

right,... Number, String and Booleans are objects

[vocal elbow]

let mainhandItem = event.source.selectedSlot;
event.source.runCommandAsync(`say ${mainhandItem}`);``` why doesn't it returns me 'undefined'

?

[distant gulch]

no i made

JSON.parse("true");

[amber granite]

Bro

The true , false etc...

[granite badger]

https://jaylydev.github.io/scriptapi-docs/latest/classes/_minecraft_server_1_11_0.Player.html#selectedSlotIndex selectedSlotIndex

[amber granite]

Don't get quoted

And when u parse them

U will get the value

And his type

Again

[distant gulch]

player.selectedSlot
```shouldnt exists

but selectedSlotIndex does @vocal elbow

@amber granite sooo

should i save it like that:

// key:startIndex,length
let addresses = "PI:0,5,PI2:6,5,A_STRING:12,8"
// value,value,value...
let values = "3.141,6.282,a string"

[amber granite]

No

[distant gulch]

and slices them by the addresses

okay?

[amber granite]

U should save like that
