Script API General

[loud frigate]

my guess its something to do with how the client entity is rendered and interpolated

[dim tusk]

1.21.80 which is preview.

[prisma shard]

Or could be your script is laggy

[prisma shard]

/**
 * Shoots a projectile entity from a player's view direction.
 * @param {string} projectile The projectile typeId to shoot (example, "minecraft:arrow")
 * @param {number} power The speed of the projectile
 * @param {Player} source The player or entity to shoot the projectile from
 * @returns {Entity} The projectile
 */
export const shootProjectile = (projectile, power, source) => {
    const headLoc = source.getHeadLocation();
    const viewVector = source.getViewDirection();
    const direction = {
        x: headLoc.x + viewVector.x,
        y: headLoc.y + viewVector.y + viewVector.y * 0.4,
        z: headLoc.z + viewVector.z,
    };
    const vel = { x: viewVector.x * power, y: viewVector.y * power, z: viewVector.z * power };
    const entity = source.dimension.spawnEntity(projectile, direction);
    entity.getComponent("projectile").shoot(vel);

    return entity;
};```
How about  you could use this function to shoot the projectile from entity

try adjusting the power

[dim tusk]

Client problem or you're script is running heavy before spawning it.

[prisma shard]

👆 this i was talking abt

[prisma shard]

^

[loud frigate]

yeah thats pretty much what i got

[dim tusk]

just use function.

and btw, what's the purpose of adding vectorY twice and multiplying by 0.4?

[chrome flint]

i just changed my script version manifest to 2.0.0-beta, how do i fix this?

[loud frigate]

so do you not have some initial delay with that code?

[prisma shard]

no

the same

[little hull]

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

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

    if (entity && entity.typeId === "zombie:explosion_cast") {
        const projectileComponent = entity.getComponent("minecraft:projectile");

        if (projectileComponent && projectileComponent.owner) {
            const owner = projectileComponent.owner;
            world.sendMessage(`Projectile was shot by: ${owner.typeId}`);
        } else {
            world.sendMessage("Projectile has no owner.");
        }
    }
});```

[little hull]

can someone plss help me

[native patio]

Hi

[loud frigate]

without using runtime identifiers?

[prisma shard]

huh

[patent bane]

oof, thanks tho

[warped blaze]

worldLoadAfterEvent

you can't read the property if the world hasn't loaded yet

[warped blaze]

say what the problem/error is and what are you trying to do, don't just send the script like that and ask for help without any context

[chrome flint]

i see, thank you

[buoyant canopy]

wait, can we not allow for more than 1 stack of items in a custom bundle

well, this puts the nail in the coffin for my custom equipment slots project

why is it not mentioned in the docs?

[wary edge]

It is.

[buoyant canopy]

not in this document

https://learn.microsoft.com/en-us/minecraft/creator/reference/content/itemreference/examples/itemcomponents/minecraft_storage_item?view=minecraft-bedrock-stable

[wary edge]

lol they removed iut.

[dusky flicker]

man, im making a way to addons send requests to a server(another addon) and receive a response from them

the thing is that if the client and the server dont block the thread, they do 10 requests per second due to runJob

the client executes runJob, the server as well so 2 runjobs, 2ticks lost

if both block, it can send up to 100 requests per second

but im planning to do something like merging a lot of requests in once

and send this single one

https://github.com/cykna/otsuki-addon/tree/master/behavior_packs/Enchanted/src
to understand it better, here's the repo

const client = new EnchantedClient({
  target: "enchanted",
  piece_len: 2048,
  uuid: "seupai"
});


world.afterEvents.playerBreakBlock.subscribe(async e => {
  let i = 0;
  const now = Date.now();
  while (Date.now() - now < 1000) {
    await client.send_object({ "route": "/" });
    i++;
  }
  console.log("Sent a total of", i, "requests");
});```
the code im running on minecraft

no i cannot use system.currentTick, both block thread, so the tick does not run

for some reason

anyways, i pretended doing something to merge them all

but actually im tired as hell of implementing this and having 1001 problems with some random request index

and now my brain is a bit slower so i cannot think in something

could someone help me?

i thought in using some kind of queue, for the sent content before actually sending, but it gets compressed

and i dont pretend compress each request made and put them together and then send, that would be heavy

just some way to predict the compressed size of the current sent request would be good

[hollow sail]

is there some other place to set scripting api version

i have the package version 1.18.0 but when i play the pack in preview i get errors because i guess its trying to load as 2.0

none of my components are registering

[round bone]

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

1.18 should be a last version

[hollow sail]

Yeah I have it set to 1.18

[round bone]

what errors are you getting?

[hollow sail]

In vs code it says worldInitialize is deprecated

And in game subscribe is undefined

And so is registerCustomComponent

[round bone]

what typings are you using?

NPM versions

[round bone]

I think that the name has already changed for 1.18 release

Use worldLoad

[hollow sail]

Oh

[hollow sail]

Wdym?

[round bone]

What are your NPM package versions

[hollow sail]

sorry,

"@minecraft/server": "1.18.0",
"typescript": "^5.4.5"

i also can't find worldLoad anywherew

[round bone]

hmm, weird

[thorn flicker]

its worldInitialize in 1.18.0

[hollow sail]

Not for me

For some reason

Well I don’t even see worldload so I dunno

[sweet seal]

How to make banner red?

          const banner = new ItemStack("minecraft:banner", 1)
          banner.lockMode = 'slot'
          inventory.setItem(player.selectedSlotIndex, banner)

[sharp elbow]

Heh, I guess you can't. Color must be stored in NBT somewhere.

Unless you can give data values with scripting?

[little hull]

world.afterEvents.entityHitEntity.subscribe((event) => {
    const damager = event.damagingEntity;
    const damaged = event.hitEntity;
    if (damager && damager.typeId === 'zombie:megumin') {
        if (damager.hasComponent('minecraft:behavior.melee_attack') === true) {
            damaged.runCommand("summon zombie:explosion_majic ~ ~ ~");
        }
    }
});

world.afterEvents.entityHitEntity.subscribe((event) => {
    const damager = event.damagingEntity;
    if (damager && damager.typeId === 'zombie:megumin') {
        if (damager.hasComponent('minecraft:behavior.delayed_attack') === true) {
            damager.triggerEvent('zombie:tired');
        }
    }
});```

[little hull]

does the checking of component is correct?

[warped blaze]

how does the arguments part of using a custom command work?

customCommandRegistry.registerCommand({...}, ({ origin, args }) => { //the "args" part in this line
  //???
});```

nvm i just figured it out

so obvious, but my brain wasn't braining

[echo tinsel]

Is it possible to set up a script that when an attachable is on an armor stand that when using an item on the armor stand it changes the attachables geometry(and the attachable keeps the geometry when taking it off the armor stand) based on the item used

[patent bane]

do commands actually run significantly slower than scripts?

[shy leaf]

depends

its kinda indistinguishable with our bare eyes but

in mass quantity, scripts are significantly faster

[patent bane]

ah ok, thanks!

[shy leaf]

and its generally recommended to use native functions if possible

runCommand is a Plan B

[deep quiver]

something like /clear is probably faster as with script you gotta iterate through all slots and make an api call each time, instead of running just one command and letting the c++ handle it

But yeah you should usually do the script api methods

[patent bane]

i see, thanks

[hexed fox]

world.beforeEvents.chatSend.subscribe((data) => {
const player = data.sender;
const msg = data.message.toLowerCase();
const command = CustomCommands[msg];
if (!command) return;
system.run(() => command(player));
data.cancel = true;
});

Manifest part:
"dependencies": [
{
"module_name": "@minecraft/server",
"version": "1.3.0"
},
{
"module_name": "@minecraft/server-ui",
"version": "2.0.0-beta"
}
]
}

How to fix the bug?

[patent bane]

i think you might have the versions shifted

[patent bane]

server is supposed to be v2.0.0-beta
server-ui is supposed to be 1.3.0

it should be like dis:

    "dependencies": [
        {
            "module_name": "@minecraft/server",
            "version": "2.0.0-beta"
        },
        {
            "module_name": "@minecraft/server-ui",
            "version": "1.3.0"
        }
    ]

[sterile epoch]

I think both server and server UI have to be beta

[leaden elbow]

checking player if is op is a property or a method?

[nova flame]

is there a way to make blocks in a certain area explosion-proof?

[patent bane]

i think its a method? im unsure

yeah its a method

[honest wave]

how to write values using js? Example: if player moves script writes value "moving": true in json file, when not then fald?

[wheat condor]

You can’t write files

Only bds

[fallen cape]

Can't save data to files

[leaden elbow]

modalform body is not a thing anymore?

[round bone]

the closest thing you can do is:

1. use a back-end server (Express will be probably the best choice for things like this)
2. handle on back-end player's moving state
3. send HTTP requests from Minecraft server

cons:

• you must use also a HTTP request to get from back-end server the state of moving back (on Minecraft server)
• you would have to host additional Node.js

[slender aurora]

Hello 👋
I am just starting with scripting and wanted to ask: What is the differenz between scripting in javascript and typescript?

An are there some tutorials to easyli get started? I mean I have seen the Microsoft learn things, but even with them I don't really know how to dive into the topic of scripting 😅

[remote oyster]

TypeScript is a superset of JavaScript. It adds features to JavaScript, mainly static typing. Due to its design for static typing it helps to catch a lot of runtime bugs without necessarily having to load up a Minecraft World and test in-game. Cuts down debugging immensely.

The engine expects it to be JS. Developers will write the code using TS but then later transpile their scripts to JS for distribution/additional testing.

[wheat condor]

Javascript is very similar to Java but it isn’t based on variable types meaning that you can assign everything as a const

Typescript is JavaScript but you have to declare types, they are basically the same language in a different version of it

[prisma shard]

actually

since You guys are talking about typescript, Can anyone clear my doubt?
I have a confusion about TS

[slender aurora]

So if I sript, I will just always make it a .ts file?

[wheat condor]

No, Minecraft accepts only js

[remote oyster]

It's not required but if you want static typing to help ensure proper coding style while using the API's then it's recommended, but you can most certainly just use .js. JavaScript has JS-Docs as well which can be used to define and enforce typings in your script, but that is not necessarily required either. Though recommended in either case.

[wheat condor]

Typescript is made to add TYPE definitions to avoid type errors, like your npm package uses a .ts file to generate your type auto completions for visual studio

[slender aurora]

Okay, then I will write my script in a .ts file and if I want to test it in Minecraft, i will just change the extenion to .js?

[copper egret]

is there a technique for damage and knockback cancelation?

[wheat condor]

JSON editing

[copper egret]

I know that method but I couldn't do it dynamically like the filter and tag things

[wheat condor]

Ask in entities thread

[remote oyster]

No, it will need to be transpiled from .TS to .JS. You will need to set up your environment to basically compile/convert them to JavaScript. This typically implies having a script handle that process. Usually in a file called package.json.

[prisma shard]

So, A doubt I have about TypeScript.
I know minecraft Script API itself doesn't support TS, And so You have to do tsc --watch, which automatically compiles the TS to JS , so you can load it in world. But.. TypeScript has some speical features, which JS don't have, such as Interface, If you put a code of interface inside a online Compiler, it will turn out.. Nothing as JS. SO how does minecraft itself reads it

[slender aurora]

Do you know where I can finde a tutorial on how to set it up?😅

[prisma shard]

search engine exist

[wheat condor]

Interfaces are just types of things that aren’t actually a class or a variable, like

Vector3 isn’t a class or a variable it’s just an interface used to give a name to the object
{x,y,z}

It’s done so if some function require a Vector3 you know it’s x y z

[prisma shard]

i see

and what do you put inside manifest.json for the script path? does tsc --watch makes a compiled JS in background? Or a JS file next to the TS? But i seen developers have no JS file, in thier addon path.. Do you put the TS path in manifest.json? Or the JS

[remote oyster]

In TypeScript, an interface defines the structure of an object, what properties it should have and their types. This helps the development environment provide real-time feedback, like autocompletion and error checking. JavaScript doesn’t need interfaces because it’s dynamically typed, it figures out object shapes at runtime. But TypeScript relies on static typing, so it needs a way to understand an object’s shape ahead of time, and that's what interfaces are for.

[prisma shard]

And this?

[prisma shard]

dont know if you mind to get ping

[remote oyster]

You typically manage everything TypeScript-related using tsconfig.json. This file tells TypeScript how to behave, like where your .ts files are, how strict type-checking should be, and where the compiled .js files should go. For example, you might say: “Take everything from the src folder and compile it into a scripts folder,” and it’ll handle that automatically.

When you run tsc --watch, it listens for changes in your .ts files and continuously compiles them in the background based on those tsconfig rules. So even if you don’t see .js files in your source folders, they’re being generated elsewhere, usually in a dedicated output directory.

This process is often paired with package.json scripts where you define commands like "build" or "watch" to trigger the compiler or prep everything for distribution. So instead of touching files manually, you automate the pipeline and keep your TypeScript clean and separate from the final output.

[prisma shard]

Oh

I understand

Thanks!

[remote oyster]

I'll use my files as an example.

yeahhh i see

Thanks for clearing my complete doubt

wait if the JS folder is outside the addon directory, how does manifest get it

becuase inside scripts folder you have TS

[remote oyster]

Nope, inside scripts folder I have .js when compiled and built. This is where your package.json comes into play, paired with your rules and instructions in tsconfig.json.

tsconfig.json

[prisma shard]

Ahhhhh

[remote oyster]

My package.json file is too big but here you go

https://github.com/Visual1mpact/Paradox_AntiCheat/blob/rewrite/package.json

[prisma shard]

Kinda janky to me, so TS is normally not used in addons scripts folder ? Then why i seen sharing repostitry addons inside it has TS...

so TS is not a thing to put in addon file

It is only for typings

I see

[remote oyster]

Keep in mind that your skeletal environment does not have to fall in line with a skeletal behavior pack. What matters is that when you compile and build it that your finished product is.

Yes, you won't put TS scripts in a behavior pack as the engine only supports JS. TS is purely for static typing to help write robust code, quickly and more effectively, while minimizing bugs and errors before even debugging in a world.

[prisma shard]

thank you very much

[remote oyster]

It also can prove to be extremely useful by establishing rules and guidelines in the tsconfig file to ensure consistency within your practices and with others who wish to contribute. Good for preventing what I call spaghetti code lol.

[remote oyster]

Yes, Mojang has a repo with one set up as an example. You will just need to familiarize yourself with it. There are also many other open source projects on GitHub with similar setups that you can review as inspiration to begin and start your journey.

The following link will walk you through the process of learning how it all works using the basic fundamental knowledge to get started.

Thanks so much for your help, everything I did was working perfektly and I can see myself getting into scripting. But I got one last question: I followed the tutorial till the end, where I set the npm via windows terminal to the watch mode with:
npm run local deploy -- --watch

Now I want to know, how I can get npm to "unwatch"
Or is it doing nothing, if I close the windows terminal or what will happen? 😅

[slender aurora]

Well to anyone wondering: I just closed the terminal and npm stoped to watch my script. So as far as I can see it does also not operate in the background anymore. If I am wrong pls let me know 😂

How do I see if isOp is to be in the new 2.0.0-stable or if it'll just be in 2.1.0-beta

[remote oyster]

It's in 2.0.0-beta.

It will work on BDS (after making a small change in server.properties), but Realms, not so much.

[frozen vine]

2.0.0-beta in 1.21.70/1.21.80 and 2.0.0 in 1.21.90

This script seems to work (the chat messages to get changed) but even if I have a rank and it goes through it shows up as undefined next to my name

world.beforeEvents.chatSend.subscribe((data) => {
    const sender = data.sender
    const message = data.message
    const ranks = sender.getTags().filter(predicate => predicate.startsWith("rank:") === true)/*?.forEach(function (item, index, array) {
        array[index] = item.substring(4)
    })*/
    const trimmedRanks = ranks === undefined ? undefined : ranks.forEach(function (item, index, array) {
        array[index] = item.substring(5)
    })
    system.run(() => {
        world.sendMessage(`§r${sender.name}§r${/*trimmedRanks === undefined ? "" :*/ ` - ${trimmedRanks?.join(" - ")}`}§r: ${message.trim()}`)
        world.sendMessage(`${ranks}`)
    })
    data.cancel = true
})```

the commented out parts are things I've already tried

[sterile epoch]

bcuz for each doesn't return anything it just modifies the original array

so the trimmedRanks will be undefined regardless of what u do

it's better to use .map

[patent tapir]

well ok

why doesnt this work then

world.beforeEvents.chatSend.subscribe((data) => {
    const sender = data.sender
    const message = data.message
    var ranks = sender.getTags().filter(predicate => predicate.startsWith("rank:") === true)/*?.forEach(function (item, index, array) {
        array[index] = item.substring(5)
    })*/
    ranks = ranks?.forEach(function (value, index, array) {
        array[index] = value.substring(5)
    })
    system.run(() => {
        world.sendMessage(`§r${sender.name}§r${/*trimmedRanks === undefined ? "" :*/ ` - ${ranks?.join(" - ")}`}§r: ${message.trim()}`)
        world.sendMessage(`${ranks}`)
    })
    data.cancel = true
})```

[rapid sail]

do i need to add it to the manifest too?

just download the minified version and put the file in your scripts folder.

and then import it into the file you'll be using it in.

[leaden elbow]

managed to make it work, now when i getItem() then item.nameTag returns undefined, and tried item.name too its also undefined

i have vanilla items in my inv btw

[cold grove]

typeId

[leaden elbow]

so if i rename the item, the nametag will work?

how about on custom items if typeid doesnt match its name

[cold grove]

In experimental version you can access ItemStack#localizationKey, to get the translation in a RawText

world.sendMessage({ translate: item.localizationKey })

[leaden elbow]

okay thanks

is that in 1.21.70?

and also one last thing is <ItemStack>.durability and <ItemStack>.isEnchanted a thing?

How to update a pack without changing manifest? So when I update a pack on my realm all dynamic properties wont reset.

[plucky light]

I am using the Mob Heads addon by 2-Tail Productions on a server I maintain and am constantly getting the below error.

[Scripting] TypeError: cannot read property 'hasTypeFamily' of undefined at <anonymous> (index.js:166)

The code it is getting generated from is below. Is this due to a conflicting pack or a change in required language?

    let damagingEntity = data.damagingEntity;
    let entity = data.hitEntity;
    if (entity != undefined && damagingEntity != undefined) {
        console.warn(entity.typeId + " output " + damagingEntity.typeId)
        let familyComponent = entity.getComponent("minecraft:type_family");```

[wintry bane]

Hold on, if add-on #1 has const add = 1; and add-on #2 has const add = 0;, which value will the variable have?

The add-on higher in the stack?

[distant tulip]

each file have it own environment, there is no conflict

you can even have const add = 0 in on file and const add = 1 in a diffrent file in the same addon

[distant tulip]

the error is not related to the code you sent

or the code is not complete

also, not sure you are allowed to share codes from mp addons

[plucky light]

Sorry was missing the last line which is the hasTypeFamily request.

    let damagingEntity = data.damagingEntity;
    let entity = data.hitEntity;
    if (entity != undefined && damagingEntity != undefined) {
        console.warn(entity.typeId + " output " + damagingEntity.typeId)
        let familyComponent = entity.getComponent("minecraft:type_family");
        if (familyComponent.hasTypeFamily(`${nameSpace}_head`)) {```

Also understood on MP addons but this developer offers the same version from on their website.

[distant tulip]

familyComponent?.hasTypeFamily(`${nameSpace}_head`)

the error shouldn't appear anyway

i assume his entity don't have a family component, if so you should report the problem to foxy

[warm mason]

useless

[prisma shard]

very useless

lol

why the entityHitEntity event would fire if the entity doesn't even exists, xD

[distant tulip]

what happen if the entity died?

[warm mason]

It will still be valid for some time.

[thorn flicker]

so the if statement here is for the some.

[warm mason]

You will always get an entity object. If you want to protect yourself from errors, you can check isValid

[distant tulip]

yeah, i guess bedrock do delay the removal

even the xp is delayed

[thorn flicker]

you could just use optional chaining

[plucky light]

It happens periodically and not necessarily when I am hitting something so I wasn’t sure if it’s related to a block update in scripting or similar as the first time it happened I thought it was falling gravel.

either way I’ll try your code as an update. Thanks

[random flint]

Except for some entities that don't have death animation.

• Armor Stand
• End crystal
• Most inanimate entity

It'll still technically give Entity class, but not valid for modification 😔

[distant tulip]

well, that is still not undefined

[warm mason]

At the same time, other functions of your addon or another one can remove the entity. So the isValid check is very justified, but not != undefined

It only sends to whomever you populate in the array.

No worries. Just wanted to make sure 😀

Yea basically haha. An array of player objects.

Be careful with using isOp(). It's effective in a BDS environment if server.properties includes the proper attribute, but when it comes to Realms, it is not reliable until they do something about the different layers of permissions and how they are handled internally.

It appears you are executing them in beforeEvent. If so, you will need to wrap those in a function and call that function with system.run().

This will offset their execution so that the read permission is elevated to read/write.

@distant tulip

what did i do wrong

[distant tulip]

why do you need that

just trigger the code the script event is triggering directly

[random flint]

1. use runCommand
2. privilage error, use system.run()

[twilit tartan]

I have a structure loading system, it divides the build into 4 sections (alligator1, alligator2, alligator3, alligator4) because the total size exceeds the 64x64 blocks allowed per structure. However, this causes problems when trying to rotate them, since each part rotates independently and becomes misaligned, and if a chunk is not previously loaded, some pieces are not placed correctly or bug and do not generate, there is no efficient way to save structures larger than 64x64 and make their rotation work. This causes the final structure to be incomplete, poorly synchronized or with visual errors, especially in large worlds or servers with latency.

I can't wait for it to be implemented

[warm mason]

I asked about this at Creator Camp

[copper egret]

yet dev ignored it since it's probably not very specific or probably they couldn't do it for a certain purpose.

They replied that it was a "complex system" and we were afraid of breaking it if we added it, but we see that you want it.

How can I copy some JSON data out of the game?

[warm mason]

you can't

[full idol]

What about putting it in a pre-filled command block or book?

[random flint]

1. Both Command Block and Book & Quill text content currently can't be read or modified by Script-API.
2. Item name, entity name, Item Lore, and text sign, Server Forms are some of the things you can assign text to with Script-API.

• If it's specifically for copying a text, you can go with Signs (The player can edit it) or better... modalForm.textField(), which is basically a text box.
  • (However, by default, they do have a character limit.)

3. Is simply using the console. You log the stringified JSON to the console and let the user copy it through the content log GUI. Which doesn't have a character limit.

• This would be limited to the server console or the world's host.

[full idol]

Thanks! Yeah I need a ton of data, exporting a map of the world. I'll use console.log

Yes.

[remote oyster]

Correct me if I'm wrong but I think it's only afterEvent.

[wheat condor]

Before event would be cool.. but like I image what cancelling the pickup of an item how would look like

[prisma shard]

    /**
     * 
     * @param {ItemStack} itemStack 
     * @param {Object} enchantments
     */
    static addEnchantments(itemStack, enchantments) {
        const enchantableComp = itemStack.getComponent("minecraft:enchantable");

        if (!enchantableComp.canAddEnchantment) {
            throw new Error("The item is not enchantable!");
        }
        if (!enchantableComp) return;

        Object.entries(enchantments).forEach(([id, level]) => {
            enchantableComp.addEnchantment({ type: new EnchantmentType(id), level: level });

        });
        //return itemStack
    }```
Umm guys what do i do here?
Do i remove the `return itemStack` or remove it? or `setEquipment/setItem` to set the item again? (i dont have equipment / container component here )

[wheat condor]

Depend on how you want it to work

[remote oyster]

That's a tough one to answer but let's follow up that question and ask if you have other functions which modify a ItemStack such as Lore? If yes, then I would say return the ItemStack so you can get all the changes at once, then set the item.

[wheat condor]

But i think that returning the ItemStack is enough becouse you let the user to do what he want

[prisma shard]

I don't want to set the item again outside the function. But to do that I have to do player.getComponent('inventrry')
And i dont want want to put the player parameter in the function

What i dooo

[wheat condor]

Bro

You re doing that script api function pack?

The ItemStack class has the enchantable component that has the SetEnchantment method that just edits the ItemStack (remember that ItemStack is an instance and not a simple object)

[wheat condor]

As I said to you 2 days ago use
ItemStack.prototype.addEnchantments
So you just run the function at the ItemStack instance without having to get a new ItemStack from the function

[shy leaf]

the player wouldnt exist if theyre not online so it wouldnt work at all

[sterile epoch]

as in, the player object is stored

[shy leaf]

where is it stored?

[sterile epoch]

in a class

[shy leaf]

hmmmmm

[sterile epoch]

is that sarcasm

[shy leaf]

no i genuinely dont really know

[sterile epoch]

oh ok sorr

y

[abstract cave]

'world.beforeEvents.worldInitialize'
was this removed or replaced

[shy leaf]

ive never had an instance where .isValid returns false since the object wouldnt just exist before i can get the boolean

so i just use it as a failsafe

player?.isValid

[sterile epoch]

that's fair, I'm just wondering because it'd be easier to check isValid instead of making a function to check if the player is online instead

i just don't have an alt to test it tbh

[sterile epoch]

it is world.afterEvents.worldLoad and system.beforeEvents.startup in 2.0.0-beta

[shy leaf]

ive never stored the player object before soooo...

cant give a clear answer, sorry

[sterile epoch]

It's all good

question, would you mind joining my world for a second so i can test it?

[shy leaf]

im on a lecture rn so i cant, sorry

[sterile epoch]

all good

[remote oyster]

Any property or method from the player object is no longer available the moment that object exits the world. Even if you copied the object to a database and accessed it later, that object won't change. It will remain stagnant.

[sterile epoch]

made a new account and tested it

isValid becomes false once the player leaves

let's goooo

easy

[remote oyster]

It's false because it doesn't exist.

[sterile epoch]

it does exist

the player object is stored

[remote oyster]

How are you storing it.

If you are copying the object then the copied object doesn't reference the original object.

[sterile epoch]

the Boolean being isValid

[sterile epoch]

just setting the player object to an undefined let

but anyways, it works and I'm happy

[remote oyster]

I don't think you understand what it's doing though.

[sterile epoch]

???

[remote oyster]

But if it's getting you the results you seek then so be it

[sterile epoch]

explain what I'm misunderstanding please

from my understanding the player leaves so the player object is no longer valid and is false

lmao bro gave up

[remote oyster]

When you copy the object into a new variable, you're creating an entirely new object. It's no longer linked to the original. This means that any changes made to the original object by the Scripting Engine won’t affect the new object, because the new object is now independent.

Think of it like this: imagine you have a bedroom, and you make a copy of it, so now you have two bedrooms. If you dismantle the bed in the original bedroom, the bed in the copied bedroom stays intact. This is because the two bedrooms aren’t connected, they are completely separate, with no reference to one another.

[remote oyster]

Not even close.

[sterile epoch]

damn the typing stopped so i thought you gave up

[remote oyster]

That was your ego speaking out loud.

[sterile epoch]

no? i just thought you gave up typing

[sterile epoch]

ok , why does the isValid become false then?

[remote oyster]

Because it doesn't exist.

[sterile epoch]

if the object didn't exist wouldn't it throw an error

[remote oyster]

Go break the object down. It may help you get a visual on what I am talking about. Do a comparison of the objects.

@sterile epoch , test and see if it's shallow copying or deep copying the object.

[sterile epoch]

idk

I'm just confused on what you mean, isn't it storing a reference to the players object?

i don't see how what you're saying makes sense if isValid changes after the player leaves

[little hull]

how do i check the owner of a tamed entity?

[solar dagger]

like this?

[shut citrus]

Why no 0.1.0

[prisma shard]

bruh wdym calculating it manually... Make it a function or um It already has a function in Vector3Utils, @minrcraft/math.js....

Oh i didnt read the full messege history

You were already replied lol

[prisma shard]

how can i detect if a ItemStack has no enchantment

the hasEnchantment() requires an string
such as hasEnchantment("unbreaking")

but I want to detect if it has any enchantment or not

[shy leaf]

make it to check if .getEnchantments() returns an empty array

[prisma shard]

how

okay a bit

hmmmmmmm

const enchants = enchantableComponent.getEnchantments();
if (enchants.length === 0) {
  // no encchantment
}```

like that?

@shy leaf

legnth right

[shy leaf]

maybe

[prisma shard]

i hope so lets try it

[prisma shard]

Is there any way to force player into sneak mode

[woven loom]

block movement if they arnt sneaking

👀

[prisma shard]

huh

[somber cedar]

https://jaylydev.github.io/scriptapi-docs/latest/classes/_minecraft_server.Player.html#example-alwayssneakts dunno if this works

[stuck ibex]

Yeah isSneaking isn't readonly

[distant tulip]

Player.isSneaking = true

[prisma shard]

hwhwoa-dhadas-das

[prisma shard]

SNEAKING ISNT READ ONLY !??!

My whole life was a lie. 😭

lmao

[distant tulip]

lol

[prisma shard]

is isJumping also not readonly

would doing isJumping = false
make not allow to jump?

[prisma shard]

.

/**
 * Forces the player into sneak mode.
 */
Player.prototype.forceSneak = function () {
    this.isSneaking = true;
};```
It doesn't show the typings

when i type player.

no typeings for forceSneak prototype

[prisma shard]

also thus

[distant tulip]

eh, why do you need a prototype for one line of code

[prisma shard]

lol idk

but tell tho

[distant tulip]

not sure

[round bone]

overriding library classes is not a good idea tbh

also, this is just a one line, so why you have to use a new function to force someone to sneak

[prisma shard]

meoew mew lol

ok ok ok idk

I will not do the prototype

/**
 * Run multiple commands at once.
 * 
 * @param  {...string} commands
 * 
 * @example
 * player.dimension.runCommands(`say Giving apple to player`, `give @s apple 1`, `say Done!`)
 * 
 */
Dimension.prototype.runCommands = function (...commands) {
    for (cmd of commands) {
        try {
            this.runCommand(cmd);
        } catch (e) {
            throw new Error(`Failed to run commands:`, e);
        }
    }
}

is this silly to do

:)

lol

[prisma shard]

what do you think about it

[prisma shard]

^

[round bone]

/**
 * Run multiple commands at once.
 * @param {...string} commands
 * @example
 * player.dimension.runCommands(`say Giving apple to player`, `give @s apple 1`, `say Done!`)
 */
Dimension.prototype.runCommands = function (...commands) {
    for (command of commands) 
        this.runCommand(commands);
}

you're throwing an error anyway, so why catching it?

[prisma shard]

what?

throwing error anyways?

oh wait i see

lol it was silly i knew

[shy leaf]

its weird though

because the sneaking persists for like, less than a tick

it prolly depends on client fps

[prisma shard]

eh weird

uh

how about doing in runInterval

[shy leaf]

_ _

[prisma shard]

ok i se

[shy leaf]

the player would shake crazy

[distant tulip]

https://tenor.com/view/shift-gif-20546001

[shy leaf]

does the player have to sneak?

[prisma shard]

huh

[shy leaf]

like

is it a requirement or

[prisma shard]

no

not

[shy leaf]

whatcha trying

[prisma shard]

idk

making some utils

[prisma shard]

how da hell you do blank msgs

[shy leaf]

you could try this method

or you can check for player input

and make it work only if player is holding shift (sneak key)

[distant tulip]

what if we disabled the input permission for Sneak

[shy leaf]

the only downside is that mobile touch controls keep the sneak button for a tick and release

[prisma shard]

player.runCommand("inputpermission set @s sneak disabled");

wait i thought of this

how about doing this

[distant tulip]

native methods

[shy leaf]

there should be InputPermission method for Player

[prisma shard]

i mean yeah

i do know t has native mthods

but

what happen if we do this

[wary fjord]

If we remove animation will it remove from all server forms, even custom ones?

[shy leaf]

the tick delay would bash you

[distant tulip]

player.inputPermissions.setPermissionCategory(5, false)

[prisma shard]

wtf wait its rainng
I

I FOROGR THE CLOTES

it was dryingh

[shy leaf]

back to the beginning

[distant tulip]

"lets inform BAO members before i go collect them"

[prisma shard]

back

[prisma shard]

wait Is it possible to get hunger?

[shy leaf]

no

[prisma shard]

hunger comoponent exist tho

[shy leaf]

we lack in attribute component for api

i get the health and movement part but what on earth is up with the rest of two

attribute component is just very undercooked rn but

i hope we can see more in the future

[prisma shard]

    /**
     * @param {Player} player
     * @returns {boolean} 
     */
    static isMoving(player) {
        const vel = player.getVelocity();
        if (vel.x !== 0 || vel.y !== 0 || vel.z !== 0) return true;
        else if (vel.x === 0 || vel.y === 0 || vel.z === 0) return false;
    }```

i made this thing

will it work

does it have any issues or it will work fine

Maybe or i can optimize it more?

[shy leaf]

instead of checking for every direction, try this:

Math.hypot(vel.x, vel.y, vel.z)

const speed = Math.hypot(vel.x, vel.y, vel.z);
return speed > 0;

[abstract girder]

how to detect damage per second

[plucky light]

what is wrong with this code? It returns player was undefined

  const player = event.player;
  if (!player) {
    console.warn("[DEBUG] playerJoin triggered but player was undefined.");
    return;
  }```

using "@minecraft/server","version": "1.18.0"

[remote oyster]

https://stirante.com/script/server/1.18.0/classes/PlayerJoinAfterEvent.html

[prisma shard]

WorldAPI.afterEvents.playerJoin.subscribe((event) => {
  const player = world.getPlayers({ name: event.playerName })[0];
  if (!player) {
    console.warn("[DEBUG] playerJoin triggered but player was undefined.");
    return;
  }
})

[remote oyster]

Would be more efficient to use the player spawn event.

[prisma shard]

yeah

if (!event.initialSpawn) return;```

doing this will make it like playerJoin

[remote oyster]

Yea, the only con is you have an event being triggered more often versus the other. So its a matter of weighing the pros and cons. In this instance it's probably worth it.

[prisma shard]

/**
 * Forces the player to look at a specific target position.
 * 
 * @param {Player} player
 * @param {Vector3} targetPos
 */
function lookAt(player, targetPos) {
    const head = player.getHeadLocation();
    const dx = targetPos.x - head.x;
    const dy = targetPos.y - head.y;
    const dz = targetPos.z - head.z;

    const distanceXZ = Math.sqrt(dx * dx + dz * dz);

    const yaw = Math.atan2(-dx, -dz) * (180 / Math.PI);
    const pitch = -Math.atan2(dy, distanceXZ) * (180 / Math.PI);

    player.teleport(player.location, {
        rotation: { x: pitch, y: yaw },
        facingLocation: {
            x: targetPos.x,
            //substracting from player's camera height (-1.62)
            y: targetPos.y - (player.getHeadLocation().y - player.location.y) - 0.1,
            z: targetPos.z
        }
    });
}```
Also, need some help
Can you tell me if the math is correct

I'm trying to make a function, that forces the player to look within the location

[remote oyster]

I would probably need to run it on a computer and verify the numbers but I'm at work.

[prisma shard]

No problem

[remote oyster]

Also, if anyone is in the OSS server, I got a question there.

#879773489601585244 message

Actually, I'll just open the question here.

[fallow minnow]

does anyone know how to actually fetch the open ai api through server-net?

[remote oyster]

https://discord.com/channels/523663022053392405/1367092934066835517

[plucky light]

still says playerJoin triggered but player was undefined

[wheat condor]

It’s becouse the player joined, but the player as entity is not loaded yet, you have to use playerSpawn

[ivory bough]

How to make it so that only 1 entity of the same family can exist at a time?

[wheat condor]

What do you mean by “family”?

[prisma shard]

get all entities then do .filter(() => ) to exclude out the one entity getEntities({families: "monster"})[0]

then you can kill other entities

so the one entity will only exist

idk what i jsut said

someone correct me

i just threw words out of mind

[wheat condor]

That’s a bad way of doing that

You can listen for EntitySpawn event, get all the entities:

if there is alredy one entity in the world from that family remove the spawned entity

Without checking every tick

[prisma shard]

though

i didnt tell him to check every tick

Srry

[round bone]

no problem, just don't spam it here

[honest spear]

Hello BAO scripters whats is going on today?

[honest spear]

you are so true ngl

[round bone]

yeah

[honest spear]

yea

[round bone]

waiting for next stable right now

[honest spear]

nice

[round bone]

is 1.21.80 coming out today or in the next week?

[honest spear]

idk, but what feature are you look for the most?

i think there are inventory events for player right?

[round bone]

I want to see how slash commands will be working in a stable look

[honest spear]

i might be wrong tho§

ahhh

true

[round bone]

this is the second thing that I am waiting for

[round bone]

I am still thinking how they missed an origin param in command handle

[honest spear]

i wish i had more time of free time for script api

[round bone]

😭

[random flint]

I make each ItemType from ItemTypes.getAll() be placed on a furnace every time the script reloads so I get the most accurate Item Smelting recipe.

[honest spear]

isn't it the first param?

[round bone]

I haven't been using script API for like 4-5 months for something bigger

just few commisions

[honest spear]

interesting

[round bone]

it is right now, but in the first release of them, it was missing

[honest spear]

ahh i still think we are not getting whole execution information but i already said so for scriptEvent

target and execution location are two separeted things

same for dimension and more

its not always the target's one

[round bone]

at this moment, I think that using some proxy or mod-loader is a better options for slash commands

[honest spear]

yea, depends on your usecases

i would preffer vanilla if i could

[remote oyster]

I'll probably continue to create custom commands with help as a parameter to get information about the command.

[round bone]

I prefer using Script API also, for stability, but sometimes community makes better things

[honest spear]

2 days before navi released custom commands i started working on my own command parser with syntax feedback

💀

[round bone]

it's a sign to work on a wrapper for new commands

[remote oyster]

Yea, I just parse commands. More control. The idea of having commands show up in the chat window seems fine, but I've never had issues with parsing commands. Been a thing since coding was born. It worked then, it's worked all these years, it will work in the future.

[honest spear]

yea

[round bone]

parsers sometimes might be a struggle

slash commands are fixing it in some way

[honest spear]

depends

[remote oyster]

I feel like it may present restrictions.

[honest spear]

but UI feedback is really in need

but parsing it self is not problem, TypeScript is parsing whole Typescript so parsing has almost no limits

[remote oyster]

Just your imagination

[honest spear]

i hate my imagination

[remote oyster]

Haha

[honest spear]

bc it produces 3 useless project per month

[round bone]

yeah, it's not a problem

for fresh programmers it might be a bit

[round bone]

my imagination is like a rainbow

[shell sigil]

Is there a way to save an object or array to an entity so that the data is retained even after I exit the world
How I can put this to entity
Example
[1,2,3,4,5]

[round bone]

and I am a colorblind

and that's how I am making front-end for websites

[honest spear]

dynamic properties

and JSON obejct

[round bone]

stringify array and save it to dynamic property

Entity.setDynamicProperty("some-key", JSON.stringify(yourArray))

[shell sigil]

It's working thanks

[round bone]

no problem mate

👌

[honest spear]

player use entity with low-capital first latter it hurt my eyes 🤓

jk

Entity.prototype.setDynamicProperty("some-key", JSON.stringify(yourArray))

[round bone]

this is a prototype

yeah

I am too lazy to type prototype

[random flint]

wha- whyy???

[round bone]

also most of those people aren't even that deep-diving into JS

[random flint]

howwww

[honest spear]

the guys could get not a function error bro

poor guy

why did you do that to him

[round bone]

this guy is 2 steps ahead us all

that's why he did it!

[honest spear]

I wonder how is your JS skills doing 👀

We have special event in scripting discord server

and you can check the questions that are based on JS knownledge

[round bone]

we ain't doing pure JS here

I prefer royalty and TypeScript

[honest spear]

all right, but that questions are really tuff

[round bone]

https://javascriptquiz.com/

this is confusing sometimes

[honest spear]

yea i know this one

but i make something that counts on JS knowledge and not fun facts

[round bone]

"umm, this is production-level code" 🤓

[random flint]

you mean the weird af requirement? 😭🙏🏼

Listener.thingy += someFunction
Listener.trigger()
Listener.thingy -= someFunction

[round bone]

why would someone even write this for production

😭

[honest spear]

not mean to be for production

but yea

[random flint]

Imma intercept the Function class prototype lol 🙏🏼
too bad my form was cleared after I left it unsent for 2 days

[round bone]

I am a type of guy who tries to keep everything organised

that's why I like everything strict, OOP and optimised as much as I can

[honest spear]

i hate OOP in JS

[round bone]

also

OOP in TypeScript is pretty good ngl

[honest spear]

functional is better for JS

OOP with typescript is not bad

but always depends on your cases

for scripts in general i prefer functional

[round bone]

I always try to put everything in classes

also grouping functions in a class with a private constructor as static methods is pretty good

[honest spear]

yea thats one of the things i do as well

static class only with private constructor is good

[valid ice]

The only OOP I know is when my world crashes and I go "OOPS"

[round bone]

import { MinecraftMessageMode } from "@prisma/client";
import { ConnectionManager } from "../../../globals/managers/ConnectionManager";

class MinecraftMessagesService {
    private constructor() {}

    public static async deleteAndGetMessagesMode(mode: MinecraftMessageMode) {
        return await ConnectionManager.getDatabaseConnection().minecraftMessages.deleteMany({
            where: {
                server: mode
            }
        })
    }

    public static async addMessageToMode(message: string, mode: MinecraftMessageMode): Promise<void> {
        await ConnectionManager.getDatabaseConnection().minecraftMessages.create({
            data: {
                content: message,
                server: mode
            }
        })
    }
}

export { MinecraftMessagesService }

that's some example from my code

[honest spear]

already don't like that tab size

[random flint]

I put random BS on my main.js file and pray it works 🙏🏼

[round bone]

I don't like tab 2

[honest spear]

but yours is 5?

[round bone]

it's 4

[honest spear]

ohh

damn

why it looks so spacy

[round bone]

I don't know

[distant tulip]

i don't think i ever used classes in script api

[honest spear]

yea also script api is designed a bit differently

[random flint]

You should. It's like comparing a tidy room with mine

[round bone]

in my IDE it looks okay

[honest spear]

maybe its bc i don't like how long your lines are

[round bone]

import { MinecraftMessageMode } from "@prisma/client";
import { ConnectionManager } from "../../../globals/managers/ConnectionManager";

class MinecraftMessagesService {
  private constructor() { }

  public static async deleteAndGetMessagesMode(mode: MinecraftMessageMode) {
    return await ConnectionManager.getDatabaseConnection().minecraftMessages.deleteMany({
      where: {
        server: mode
      }
    })
  }

  public static async addMessageToMode(message: string, mode: MinecraftMessageMode): Promise<void> {
    await ConnectionManager.getDatabaseConnection().minecraftMessages.create({
      data: {
        content: message,
        server: mode
      }
    })
  }
}

export { MinecraftMessagesService }

[honest spear]

man this chaining is crazy

i wrap the code when there are more chained accessing

[distant tulip]

idk, i never been in a situation where i needed it
basic js stuff is more than enough

[honest spear]

but the code is not bad eather just sayin

[round bone]

it's an express app with clustering, I need to prevent creating a connection for primary worker

the minecraftMessages is a Prisma model

[round bone]

just my formatting

[random flint]

I agree. 🙏🏼

[honest spear]

btw i have something similar

[round bone]

I have set 200 printWidth in Prettier

[round bone]

68 line...

why both pairs in the same line?

[honest spear]

i don't like prettier settings

[round bone]

Prettier is customizable

and easy to use for newbies

[honest spear]

not customable enought

but its good

[round bone]

what is Prettier missing for you?

[honest spear]

i don't like it bc it thinks its smarter than me

inline functions has to be in one line whole and thats different from other lines

[round bone]

oh I understand

[honest spear]

there are more little things i want

[round bone]

I like using Prettier just to keep with the standards

[distant tulip]

i feel the same way, but i learned to live with it, lol
don't want anyone to see my weird formatting

[round bone]

also I can style in a easy way some code of my friends that is horribly organised in some cases

[honest spear]

anyway i just wrote Raknet implementation and i already hate that project

[honest spear]

i use to write compilers code, basicly that stuff what TSC products

i am glad i leveled up

i use to write JS with .d.ts

[round bone]

I'm in 10th grade right now, and I think that I am much higher than everyone from my class and even school

[honest spear]

so lot of ppl asked my if where is the TS source code

[honest spear]

yea i know that feeling

[round bone]

I would use a TypeScript at this point

[honest spear]

i am using now, but i was someone else before

[round bone]

writing d.ts from a scratch is a pain sometimes

[honest spear]

i used to do so and i was pretty ok, but you have to keep in mind when you change the function in JS

[round bone]

you have to change some code in 2 places

it's like the same problem with databases

you DON'T WANT to have to change something in 2 places if you're doing it for only 1 thing

[honest spear]

¯_(ツ)_/¯

yea tell me about it

TS is just simplier on all cases

but i use to write code that wasn't even possible with TS

like static inheritance and getter overriding and other things like that

[round bone]

static inheritance?

it's possible with TS

[honest spear]

not properly

i mean for example static abstract functions

[round bone]

there's a small workaround

[honest spear]

yea

but bad

[round bone]

but not enough

[honest spear]

not forced to implement it

¯_(ツ)_/¯

[round bone]

class SomeClass {
    protected constructor() {}

    public static someAbstractMethod(): void {
        throw new Error()
    }
}

[round bone]

yeah

[honest spear]

well yea these little things i hate about TypeScript, i wish ts covered more JS style than trying to make a diff language

[round bone]

TS is a large superset of JS

[honest spear]

thats also reason why i want to create own TS compiler in the future

[round bone]

I'll stick with TypeScript for front-end absolutely

[honest spear]

yea

TS is goat

[round bone]

TypeScript is pretty good language

[honest spear]

yea

i write 80% of my code in TS

maybe more

[round bone]

I write most of my code in TS

[honest spear]

only few test scripts for local use are in JS

[round bone]

sometimes C/C++ in other projects

[honest spear]

i don't count there langs

[round bone]

but not a big fan of C langs

[honest spear]

C# is not bad tho

i like it more than Java

C++ is also noce, C is worse C++

[honest spear]

perfect ratio

https://tenor.com/view/golden-ratio-goldenratio-spin-rotate-gif-7569189

[remote oyster]

Lol

[remote oyster]

As much as I dislike Windows, I do actually like C# and it pains me to say that haha.

[honest spear]

i like windows bc i can play bedrock on it

[round bone]

I like more Java than a C#

but I don't know about Kotlin tbh

[honest spear]

Kotlin is something that my brothe use

idk for what tho

maybe for mobile app development

[round bone]

most of people that are using Kotlins are secret fans of Java, that can't claim that they like Java to themselves xD

Linux is pretty good, but I prefer Windows just for MC:BE

also Windows has a bit better look, even if Linux is much more customizable

[honest spear]

I have been learning Python for 3 months in 2020

then started with some basic web-dev (HTML/CSS)

[honest spear]

After he showed me the C# i was sure i don't want to do that, so i left all that stuff for another 6 months but .bat files were not good enought so i have to learn real lang

[round bone]

then moved onto JS and React,js

and I don't really remember how it went then

wait, I have learned add-ons development before React

[honest spear]

i grow up on .bat files

bc dad showed them to me

the only language that my 11-yo brain was able to process
