I see. Packets are honestly not much different than just loading data from disk. Just that the data is sent by someone else.

[shadow night]

with basic knowledge of programming you could probably remake the minecraft packet system in like 30 minutes

[lost matrix]

A limbo with a keepalive could be done quite quickly. The handshake might be the most tricky part honestly.

[twilit creek]

Yea the theroy behind it is nothing "really" new for me. I'm doing it also at work but the practicle thing behind it (java) is a bit interesting for me as im working also with Java as programmer.

[shadow night]

true

why is this not named "CraftBukkitScheduler"

[chrome beacon]

Craft is just the implementation prefix

[shadow night]

damn, I'm depressed now

[twilit creek]

I'm programming for 7 years but the practicle part behind network (based) programming is something i'm not really in to it. On the side of Minecraft i have a better understanding because of the experience i've made in the past years.

[lost matrix]

Just realized that im already 4y into programming now o.O
Time flies

[shadow night]

hmm, I'm wondering rn, what would be better, an async timer task that schedules stuff to the main thread whenever needed or just a normal timer

[chrome beacon]

Java edition just uses TCP connections to the server

[lost matrix]

Depends on what you are doing and how much you want to bother with thread safety.

[twilit creek]

i know like i said, the theory is nothing new for me but in reality the core/kernel logic in programming is new for me.

[chrome beacon]

A bit over 6 years for me

[shadow night]

I'm basically making a plugin that lets you interact with bukkit through an external program

it started out as a meme, basically, so don't ask any stupid questions cuz this project is stupid in general, okay?

[hybrid turret]

Just out of interest bc I'm meaning to implement a SQLite database into the plugin eventually. Would it make sense to store a json string in a database?
It sounds stupid, but I don't know how else I could store ItemStack-Arrays in a database.

[hazy parrot]

Would it make sense to store a json string in a database?
It wouldn't

that is why relations exist

[eternal oxide]

If it's interacting with the outside world, run it Async and only jump on the main thread when you need to.

[shadow night]

another issue I thought of is ticks

[lost matrix]

In that case you just throw everything into a queue and poll everything from it each tick.
There are really nice thread safe queues which let you stack on top with multiple threads from one side and poll with another thread from the bottom.

[hazy parrot]

i just noticed, are u asking how to store Itemstack or how to store array of items

[eternal oxide]

I'd keep it all seperate. You never know when someone will spam your external interface.

[shadow night]

like, if the external thing executes something expecting it to run in this tick, what's the chance that something will run a tick after?

[hybrid turret]

Basically store a custom inventory

Like an item vault

[eternal oxide]

always assume everythign runs a tick later, other than schedulign inside an already running task

[lost matrix]

I mean a single ItemStack as json in a DB sounds reasonable. But the rest should be done through relations.

[hazy parrot]

yeah that is why i asked again

[hybrid turret]

ohhhhhhhhhh

Yeah then that

[shadow night]

hmm

[hybrid turret]

Storing the whole inventory is only the final goal

So I then basically use a combination of SQL-statements and GSON?

Not related to your issue, but you've set it to an invalid version

I'm trying to use ProtocolLib to make players partly invisible (i want their armour to be seen - like with an invisibility potion) - I've sent invisibility potion packets to the players and it seems like the client knows they have the effect however the player is just not appearing invisible, does anyone know if there is a different packet for making a player actually become invisible?

[young knoll]

Appearing invisible for themself or for others?

If you want them to be invisible for others you need to send that packet to the other players too

[terse pumice]

To others (currently I am also sending it to themselves just because I am trying to understand why it's not working haha)

Even with the effect I am still fully visible aha

[shadow night]

the ininvisibility effect

Would it be fine for the server to handle me looping thru a large ammount of blocks and doing checks with each.

I have a big stone cube and i need to loop thru it and find a random location that isbinside the cave to spawn a block. I tought about checking if the block has air next to it in any dirrection then add it to the list. After its done looping it generates a random number from 0 to list lenght and selects that block.

Basicly i have a cube and inside of it i have caves carved out.

[valid burrow]

depends

on many things

how strong is the server

how many blocks

are the blocks already loaded

[young knoll]

How often

That’s a big one

[valid burrow]

all of these mattee

?tas i guess

[undone axle]

https://tryitands.ee/

[young knoll]

I once looped over every block in a chunk to look for caves

When the chunk first generated

[icy monolith]

I can also generate the list before and save it and then just pull a random block out of that

[forest pumice]

I have a file for my custom yml files inside "resources" of my plugin folder. When I load my configuration files, do I need to do something specific because it is in the resources folder? Or can I just do something like:

plugin.getDataFolder().getAbsolutePath() + File.separator + "YamlFiles";

[eternal oxide]

new File(plugin.getDataFolder(), "yamlFile")

so long as you saved it first

[forest pumice]

thats it?

[eternal oxide]

plugin.saveResource("yamlFile")

[forest pumice]

yeah I do have a save check method if it doesn't exist on onEnable

but like it doesn't matter what folder its in?

[eternal oxide]

it defaults to the plugins data folder

[forest pumice]

which is resources?

[eternal oxide]

or are you talking about a folder inside your resources?

[forest pumice]

yeah

a folder inside resources

[eternal oxide]

those are paths, but ok

[forest pumice]

what

[eternal oxide]

a saveResource call will extract it maintaining the structure

you need to read it with that same structure, once its saved

[forest pumice]

does that mean when using saveResource I need to also specify the folder inside resources? this is a bit confusing cause its my first time doing it

[eternal oxide]

so your path would be...java folder = new File(plugin.getDataFolder(), "YamlFolder"); file = new File(folder, "fileName");

[forest pumice]

aha

[icy monolith]

Anyone knows how to deal with SQLite exceptions? I use SQLite and ORMLite to simplify the sql syntax.
And i get an error when i try to get the databases value. And i have no idea how i can find where the issue is.
Its eather that the player is not being generated in the data base or that for skme reason it errors in the return function.

If i fix this then i can fix all of my database issues

[eternal oxide]

?nocode no error, nothing to work with

[undone axle]

It’s hard to answer a programming question without code
Oh no! You ran into a problem. But no worries, people are willing to help, but first they need to see your code. This is because otherwise, they would be providing help based on guesses instead of concrete knowledge. Whether it be a compile error, runtime error, or an unexpected output, I'm sure that if you were to provide code, you'd receive a quick solution.

[icy monolith]

I was asking if anyone has experience in it to aee who would help. I wasnt expecting a dirrect help.

Bc it is something that has to be asked in DMs

[eternal oxide]

?ask

[undone axle]

If you have a question, please just ask it. Don't look for staff or topic experts. Don't ask to ask or ask if people are awake or available. Just ask the question to the channel straight out, and wait patiently for a reply. Make sure you use the right channel regarding the topic of your question. Create a thread in case the channel is already in use!

[eternal oxide]

No reason it has to be in DMs

[icy monolith]

Ok ill ask later

when i have the error or code ready

[quaint mantle]

Hi , if mod send a message will can minecraft servers like spigot read the message ?
for example a mod say "Hello I am Mod " and in the console of server be log the "Hello I am Mod"
or be read the message on server

[shadow night]

what?

[molten hearth]

I think he's talking about is a mc mod (e.g.a forge mod) sends a custom packet will spigot be able to handle the packet

[molten hearth]

is this the case @quaint mantle or

[shadow night]

Packet channels or something

[quaint mantle]

first sorry for my bad english and second yes i mean forge or fabric or any mod api in minecraft

[eternal oxide]

if the mod uses PMC then yes

[quaint mantle]

do you mean player.sendmessage(); ?

[molten hearth]

Plugin Messaging Channel

[quaint mantle]

chatbox ?

[molten hearth]

https://www.spigotmc.org/wiki/bukkit-bungee-plugin-messaging-channel/

[quaint mantle]

oh i read it so if the message was a packet for server will server read it ?

[eternal oxide]

Server does nothing with it, unless it's in a specific channel

[quaint mantle]

ok

[icy monolith]

I fixed the error, it was a dum mistake.

It lead me back all the way to the onEnable function

Anyways, still one thing related to this. To represent true or false in the data should i just use 0 and 1. bc from what i see, you cant use booleans

[eternal oxide]

you can use Boolean IF your driver is new enough

older use Int

How in InventoryClickEvent check for inventory?

[inner mulch]

does somebody know if redis is as fast as having data in server memory?

[echo basalt]

It isn't

Average operation latency is ~1ms

If on a local machine

[inner mulch]

whats the in memory latency then?

[echo basalt]

IO

[inner mulch]

~1ms seems pretty fast

[echo basalt]

1-3ms

[inner mulch]

doesnt that mean its on the same level?

[echo basalt]

no

it means that if you want to fetch data for 100 players

[inner mulch]

1-3ms for 100 players?

[echo basalt]

no

if you do separate requests it takes 300ms

use it like any other database

async

[inner mulch]

i dont want to use it as a database, i want to use it to cache data from a real database and im not sure if its worth it as im currently caching the data myself already

[echo basalt]

You can use it as a caching layer

For example, when a player joins you fetch its data (redis first then your database )and store it on ram

When a player quits you store that data back on redis for ~30 minutes

So that if a player rejoins you have less latency

Basically you want to define a lifetime for your data

And match it to something else's lifecycle

[inner mulch]

so redis fetches from database, server fetches from redis

and redis keeps it for a period of time to reduce latency

[echo basalt]

server fetches from redis, if fails fetches from database and puts on redis

[inner mulch]

okay, may i ask are you using redis yourself and which database do you use?

[echo basalt]

I'm not workin on any projects that use redis as a cache layer as of right now

But last time I did it was mongo + redis

And it was a classroom system similar to discord servers

[inner mulch]

do you think i should just fetch from redis all the time instead of caching it on my own too. It would be much easier and solve a few issues i currently have. The reason for redis is that i created a proxy with a few servers and with my old data system i encountered issues because the joinevent is called before the quitevent.(when a player switches servers in the proxy) When reading and writing to redis all the time there wouldnt be this issue as the data would be saved on disconnecting from the proxy or joining

[quaint mantle]

someone give me example for #TabCompleteEvent ?

i wanna disable all tabcompleters

    public void tabComp(TabCompleteEvent e) {
        e.setCancelled(true);
    }```
and i tried to change tab-complete in spigot.yml

[ivory sleet]

I mean u can have a weighted local cache

and then redis be the second layer

[inner mulch]

whats a weighted local cache?

[inner mulch]

are you disabling tabcompletion to hide commands?

[quaint mantle]

yes

it looks ugly

[inner mulch]

in this case you can just set a permission for the commands that shouldnt be seen

cancelling all the tabcompletion is a not so nice way in my opinion

[quaint mantle]

well can i use bukkit permissions or i need plugin ?

[inner mulch]

you are going to need a permission manager like luckperms to get the permission to see the command, but setting the permission doesnt need any plugin

[quaint mantle]

i did this

[inner mulch]

getCommand("blabla").setPermission(string permission);

[inner mulch]

this is to hide the command for players that do not have the permission

[inner mulch]

you need to do this in the onenable method

[young knoll]

You can also just put it in the plugin.yml

[shadow night]

true

[quaint mantle]

i did this

[remote swallow]

send namespaced

[quaint mantle]

wdym

[south mason]

how can you track the transfer of an item from 1 slot to another in your inventory\chest?

[remote swallow]

change send-namespaced to false

[icy monolith]

In my SQLite data base when i set players value from false to true it some how still returns false when using the get function for that data.

The .db files are successfully created, my player id is visible and there are no errors.

The get function returns it as false even after changed to true. I even made it print out the value right after setting it and it showed it as true.

I wanted to ask a question about bukkit velocity

[icy monolith]

I said i did it, how do i send it here

[river oracle]

We don't support velocity

[river oracle]

Copy and paste

A link

Velocity is maintained by a fork of spigot thus we can't guarentee it works or any features or compatability

[icy monolith]

https://paste.md-5.net/ticorokoki.java

Heres also what the player.sendMessage() returns every time i excecute the command: (for debug)

[tribal quarry]

Im trying to apply a knock back to player based on their velocity, but it appears to show me x and z values zero and a constant value like 0.876666 on y component

[river oracle]

Oh that kind of velocity xD

[eternal night]

[river oracle]

You never know now adays some group of hooligans named some piece of software after the word velocity.

[tribal quarry]

??

no help?

[river oracle]

It's been 6 minutes be patient

[winter galleon]

whats the knockback event?

[eternal night]

Well ehm, share some code I guess. How are you fetching the velocity ? When are you fetching it

[river oracle]

I don't think there is one atm

Let's see

?jds

?jd-s

[undone axle]

https://hub.spigotmc.org/javadocs/spigot

[river oracle]

There is no such thing as a knock back event currently

[eternal night]

I mean, what would that even entail

like, from an attack ?

[river oracle]

Idk coll is making one rn look at the pr

[eternal night]

or entity collision

[winter galleon]

and how could i cancel the knockback?

[river oracle]

Set velocity to 0 I suppose

That cancels all momentum

@young knoll work faster we need knockback event for this mans

[young knoll]

Last I checked it's just waiting on merge

[river oracle]

Merge faster then coll!!!

[winter galleon]

        Player p = (Player) event.getDamager();
        Player e = (Player) event.getEntity();
        if (taserati.contains(e)){
            Vector v = e.getVelocity();
            v.setX(0);
            v.setY(0);
            v.setZ(0);
            e.setVelocity(v);
        }
    }```

like that?

[river oracle]

Code lgtm getting an error or anything?

[quaint mantle]

how do i make this ?

is this client side ?

[icy monolith]

Don't be surprised. This is SpigotMC, most of the time its disrespect and not help. I come here with a 10% chance that there is some one acualy willing to help online.

What shoudl be best way to dettect if player equip armor with rightlcick? I had this, but code gets triggret if player clicked on crafting, bed or something like that, but armor wont be equipped so my code would run and it should not.

@EventHandler
    public void onInteractEvent(PlayerInteractEvent event) {
        ItemStack handItem = event.getItem();
        Player player = event.getPlayer();
        ItemStack helmet = player.getInventory().getHelmet();
        if (event.getHand().equals(EquipmentSlot.OFF_HAND)) return;
        System.out.println("INTERACT " + player.getName() + " item: " + handItem);
        if (event.getAction().equals(Action.RIGHT_CLICK_AIR) || event.getAction().equals(Action.RIGHT_CLICK_BLOCK)) {
            if (handItem == null) return;
            if (handItem.getItemMeta() == null) return;
            if (!HelmetManager.isHelmet(handItem)) return;
            if (helmet != null) {
                if (HelmetManager.hasMaskApplied(helmet)) {
                    MaskEffect healthEffect = MaskEffect.HEALTH;
                    if (HelmetManager.haveEffect(helmet, healthEffect)) {
                        double effectValue = HelmetManager.getEffectValue(helmet, healthEffect) * 2;
                        removeHealthModifier(player, effectValue);
                    }
                }
            }
            if (HelmetManager.hasMaskApplied(handItem)) {
                MaskEffect healthEffect = MaskEffect.HEALTH;
                System.out.println("EFFECT? " + HelmetManager.haveEffect(handItem, healthEffect));
                if (HelmetManager.haveEffect(handItem, healthEffect)) {
                    double effectValue = HelmetManager.getEffectValue(handItem, healthEffect) * 2;
                    addHealthModifier(player, effectValue);

[tender shard]

Yeah if you expect an immediate response within 6 minutes to any question whatsoever, this is the wrong place indeed

also from randomly looking at your previous messages, it seems like any of your questions got a reasonable answer lol

[icy monolith]

I asked for help 1h ago. They asked for code and ignored it.

[icy monolith]

I mean yeah rearly there are people that do help. Most of the time its just loughing at people who are new to Java

[tender shard]

hm my experience is the opposite. most of the times people are here to answer questions all the time, even when looking at the javadocs for 3 seconds would have answered most questions

[shadow night]

true

I'm here to teach people to follow the fucking conventions

[minor junco]

Very true, even people that can't think straight for more than one second

¯_(ツ)_/¯

[tender shard]

also do you mean your question about some SQL thing that has 0 to do with the topic this channel is about?

or maybe I'm mixing things up rn

[eternal oxide]

He asked the SQL one three hours ago but had no code or error so I couldn't help him then

[icy monolith]

It is a Spigot java plugin that uses SQL

[icy monolith]

I pinged you to let you know that i fixed it, but it caused a new problem and i tried fixing it for 2h and then came here to ask

[tender shard]

your question is only related to your SQL stuff

and it seems like you're just executing a query and changing some values in the result instead of doing any changes to the database

you're not changing anything in the database

[tribal quarry]

I'm not here to cause argument, but, this is not the problem with spigotmc, there are different people, different solutions and the difficulty of questions vary in different ways. but Y2K's response was not a 100% correct way to deal with stuff, reading mistakes happens, especially when you are trying to answer someone else (or doing something else) but I rather do more research on more communities, code to get my answer

[tender shard]

you're just setting setBuildMode on the query result

[eternal oxide]

yeah I see no update issued

[icy monolith]

setBuildMode(mode) excecutes a function inside SettingsData class that taks the value and sets this.buildMode to mode

Isn't that used to set the data

[eternal oxide]

it doesn;t pass it back to the db though

[tender shard]

to me it looks like it only sets one field to true and that's it

[eternal night]

Why are you using ORMLite in the first place

[zealous osprey]

I want some code review.
I got this function which distributes some tasks to a ThreadPool and I want to check when all tasks were complete.
Moreover, I call this function every tick, and I want to make sure that casts which are batched in a tick also return the appropriate future and when it completes.
But it kinda feels weird to do it like this; I would love a second opinion.

[eternal night]

like, I don't wanna be rude but I presume you are not basing this on 10 years of SQL experience ?
It might be better to (at least for now) stick to doing SQL yourself

[eternal night]

ORMs are magically little unicorns that look great from far away but when you have to get close they'll bite your head off while you have to workaround some dumb restriction in their design

I would certainly not suggest them if you are trying to learn/are learning SQL

[tender shard]

you can just use COmpletableFuture.allOf which returns a Future<Void> that completes when all it's "children" have completed

[icy monolith]

So i should do daoSettingsData.update() after is what im getting?

[eternal oxide]

yes

[tender shard]

imho you should try to understand how ORMLite works in the first place before using it. I have never ever used it so no clue, but it looks pretty obvious to me that you simply changed a value in the result you got

[eternal night]

I wonder how efficient that thing is with the update() call

[tender shard]

and as I said, chatgpt also thinks that you need to call update, as I guessed

[zealous osprey]

I'm doing that.
That's the part that kinda feels weird

[tender shard]

well you're supposed to return the future that allOf generates, instead of creating your own future and completing that when the allOf future is complete

[eternal night]

any point in not just draining your queue initially ?

[zealous osprey]

fair, idk why I didn't do that

[eternal night]

this draining and adding it to both a list and the executor seems weird

[zealous osprey]

Sorry I didn't really understand that, could you phrase it differently?

[icy monolith]

I did attempt to learn it, but the syntax was just too confusing after messing arround with it for 2 days and never getting anything to work. Only thing that worked was a copy paste from a github rep that i tried studying, but a lot of the syntax looked like nonsense to me

Then i found out about ORM

[eternal oxide]

I like the look of ORM and it's tidy to use, but best to know the basics first.

[shadow night]

SQL is english in caps

[zealous osprey]

Ah I think I get it. You are wondering why I have an intermediary queue instead of processing it directly, right?

[eternal oxide]

ORM is for when you already know how it works and want to avoid writing your own queries

[eternal night]

like, why not just

public CompletableFuture<Void> processQ() {
  final List<CF<CResult>> drainedQ = new ArrayList<>();
  while(!q.isEmpty()) drainedQ.add(q.poll());

  return CF.allOf(
    Lists.transform(source, input -> {
        executor.submit(() -> {
            processCast(input)
            input.fut.complete(....)
        });
        return input.fut;        
    })
  )
}

[eternal night]

no, I mean I get the queue

if you are smacking stuff into it off thread its a valid thing

I mean, it realistically does not make a difference

don't mind me xD I'll go now. My suggestion is not smart

like, you already have a CF that wants to be completed and an executor. I don't understand the point of a queue that needs all of its abitrarily pulled "requests" to finish simultaniously. Or well, that wants to await those

but I digress, probably fine. I would not suggest a LinkedList

they are notoriously terrible

especially as you are not removing from said list

[zealous osprey]

Idk if the requests are done at the same time.
It's just important that I know when all of them were completed, cause if that ever goes over 50ms, I want to log it and do some stuff.
Moreover, I might want to use the function somewhere else and would like to use #join on the CF to wait until all my requests were completed

[zealous osprey]

Fair

[upper hazel]

in bukkit api exists event be like - "hopperEvent"?

interact block with hopper

[remote swallow]

when a player interacts with a hopper?

that would be normal interact event

Does someone know if it's possible to code fishing on lava? If so, would you mind linking a resource, i've been unable to find one

[pliant topaz]

It certainly is, but i don't know how

[cobalt thorn]

How can i use a sort of setblock with nbt data like in the command a sort setblock ~ ~ ~ minecraft:mob_spawner 0 replace {nbt} the example is from 1.12 but the 0 is the blockstate

[young knoll]

Numeric block states don't exist after 1.13

[sullen canyon]

my god (my personal not the jesus) java is great

[sterile token]

I really didnt understand what asked, could you reprhase it please

[terse ore]

if there's any way to simulate normal fishing (on water) but on lava

I want to make some special fish that can only be fished from lava

[sterile token]

oh okay, perfect. Hmn i havent really worked with fishing but now you explained better someone can read it and try to help

sorry tho

[terse ore]

no problem

[winter galleon]

how can i check if a player has an inventory open?

[eternal oxide]

you can't

getOpenInventory will always return an Inventory instance, even if you have none open

shouldnt kotlin know that it.value is a string here? I'm literally checking it the line before

[waxen plinth]

why don't you just call .toString()

won't a String simply return itself anyways

[tender shard]

ofc I could but it shouldnt be needed

[waxen plinth]

lol

just do val value = it.value.toString()

[tender shard]

I'm just wondering why kotlin thinks that a cast is neccessary

[waxen plinth]

no if needed

idk

[eternal night]

cooler kids would use the when syntax here obvs

[waxen plinth]

kotlin does that with some weird compiler checks I think

[tender shard]

the value might be null

[waxen plinth]

rather than like pattern matching

[waxen plinth]

that'll crash your current code too though

because you call toString if it's not a string

[tender shard]

yeah true

[waxen plinth]

so it'd just be value?.toString() wouldn't it?

[tender shard]

anyway the question is why is it needed

[waxen plinth]

¯_(ツ)_/¯

[tender shard]

because kotlin usually supports these auto casting stuff or however its called

[waxen plinth]

probably a case where the kotlin compiler just fails to pick it up because it's an expression rather than a scope?

not sure

a match can probably do what you want anyways can't it

[eternal night]

I mean

[waxen plinth]

is it map or switch in kotlin I forget

[eternal night]

it is calling a method there

[waxen plinth]

a field

[eternal night]

no

a method

[dry hazel]

it's needed because it's probably a property where the mutability cannot be confirmed

[eternal night]

yea

[waxen plinth]

it.value is a getter?

ohh

yeah

[eternal night]

given that is a Map.Entry yes

[waxen plinth]

you'd have to store it in a local ig

[eternal night]

or just when() that shit

[waxen plinth]

this is why sum types are better than oop

[tender shard]

value is a property

[eternal night]

what

[eternal night]

you are iterating a Map.Entry

[tender shard]

I am iterating a kotlin.collections.Map.Entry

[eternal night]

is that backed by a java type ?

[waxen plinth]

.value is definitely just calling .getValue() on the entry

[eternal night]

I don't see you converting it into some mystical kotlin type

[tender shard]

it does that automatically, see the screenshot above of IJ claiming it's a kotlin Map.Entry

[waxen plinth]

oh, huh

it must be because it's a field rather than a local, then

[dry hazel]

show what the IJ error is

[eternal night]

it is literally an abstract val

[dry hazel]

anyways it.value as? String ?: it.value.toString()

[waxen plinth]

I'm guessing the scoped downcasting only works on locals

[eternal night]

its an abstract property

kotlin is such a useful and great language

[waxen plinth]

it.value?.toString()

[dry hazel]

that's not the same thing

[waxen plinth]

got a few nice things but lots and lots of bloat

[eternal night]

Well and this shit

[waxen plinth]

it is

[tender shard]

I agree

[eternal night]

abstract properties

[tender shard]

yeah why not?

[eternal night]

well, at least I hope you understand why it is failing

[dry hazel]

you end up with a nullable type

it.value.toString() yes

[waxen plinth]

I guess you end up with an NPE if there's no value :)

[tender shard]

yeah because the property's getter might have been overridden / open and return sth different everytime

[eternal night]

indeed

[waxen plinth]

oh wait I see

value is not nullable

yeah then there's no issue

[eternal night]

good language design

[waxen plinth]

if value is not nullable then it's just it.value.toString()

[young knoll]

I can never tell if sarcasm from Lynx

[waxen plinth]

definitely sarcasm

kotlin has very mid language design

if you wanna see good lang design look at rust 🙏

[eternal night]

kotlin syntax makes rust lifetimes look sane

[waxen plinth]

lol

rust lifetimes are scary but you never really need to tango with them if you use the right tools

just throw a couple smart pointers in and you'll never need to bother with lifetimes

[dry hazel]

I will hug you

[eternal night]

Yea I mean, its a thing you don'T ever wanna touch given how leaky that shit is

[tender shard]

well it kinda is nullable as it's a platform type, getValues returns a Map<String!, Any!>

[waxen plinth]

mm

[waxen plinth]

what

how leaky what is

[eternal night]

lifetimes

[waxen plinth]

how's it leaky

[eternal night]

like, leaky as in it forces itself up the chain

[waxen plinth]

ahh

[eternal night]

same shit with like, async in js

[waxen plinth]

yeah it has a tendency to get everywhere if you're not careful

[eternal night]

Yeaaa

[waxen plinth]

but you can cut off the chain with a smart pointer anywhere

[eternal night]

But again, sane compared to kotlin

so I take it

[waxen plinth]

kotlin has too much syntax

rust has a lot more syntax I think, but it doesn't feel like it does

[summer sandal]

i need some help

[waxen plinth]

because it's all so consistent that I've almost never looked at new syntax and been genuinely clueless as to what it's doing

[waxen plinth]

with what

[eternal night]

throw your question in here ^

Ik some java not spigot api tho

i kinda made my plugin with chatgpt

[tender shard]

?codeblock

[undone axle]

You can use the discord code block format to display code or just text in a more pleasing way:
```java
public class MyPlugin extends JavaPlugin {
@Override
public void onEnable() {

}

}```
Becomes:

public class MyPlugin extends JavaPlugin {
    @Override
    public void onEnable() {

    }
}```

[eternal night]

You are supposed to head to the purpur discord pretty much 😅

given you are not using spigot

they can offer better support for their API

[summer sandal]

Im using spigot api tho

[eternal night]

Ah

[summer sandal]

i declared spigot api in pom.xml

so i came here cuz its a spigot plugin

[eternal night]

Well, you never set the instance

[tender shard]

you create a NamespacedKey using SwordProgresisonPlugin.getInstance(), which returns null

[summer sandal]

what do i change?

[sullen marlin]

Looks like purpur to me

[tender shard]

do not create NamespacedKeys with null as plugin

[summer sandal]

server softwares purpur, the plugin is spigot (Can you even make a purpur plugin)

[summer sandal]

explain it in an easier way, lmao

Im too dumb

all ik is some jsva

[tender shard]

null ^

[summer sandal]

that i learned from a youtube tutoril

remove that?

or wat

remove the red thing ?

[tender shard]

?

[summer sandal]

What do i change

to make it finally work havent slept in forever

[tender shard]

either create that key the same way you create the other key, or properly set your instance in the constructor

[summer sandal]

Ok ty ima ask chatgpt for more help

💀

[tender shard]

there should be 0 need to call your static getInstance() method if you already have an instance

you can simply use this because materialKey is an instance field

private final NamespacedKey materialKey = new NamespacedKey(this, "asd");

same for your other namespacedkey - there is little point in setting one in the constructor and initializing the other one directly

just create both using this right where you declare the field

[mental moon]

Hey all. Trying to construct Suspicious Stew via the SuspiciousStewMeta. I can build the ItemStack just fine, and the data is on there, however when eaten it does no effect.
When I looked at the data made by Spigot compared to a vanilla stew taken from the creative menu it was a little different.
Top: Spigot created
Bottom: Vanilla
Anyone know of a fix?
I wouldn't mind writing the metadata manually if someone could show me how to do that.
Thanks

[eternal night]

by opening a bug report on spigot for the incorrect behaviour

beyond that, the API does not offer a way to edit that manually

you'd have to look into things like NBT-API

[mental moon]

Understood. Wanted to ask first just in case
Thanks

[tender shard]

yikes is it the case sensitivity of "effects" lol

[eternal night]

it is

and name of duration

[young knoll]

Did Mojang change that at some point

[tender shard]

so spigot creates a sus sus stew

[eternal night]

indeed

[young knoll]

Or did spigot just implement it wrong

Ah okay

[eternal night]

lets see when paper fixed that

I wonder when they changed it

[young knoll]

Thanks Obama Jeb

        val resolvers = tagResolverFactory?.getTagResolvers(concerns)?.toTypedArray() ?: emptyArray()

[dry hazel]

yeah sure

hey, is it currently possible to do modded armor models in mc?

like not just a texture swap

for java edition

I think bedrock has it

[sterile token]

I woudl recommend fully java and then start with apis. Because with the past of the time you will just face and face more problems

[young knoll]

Shaders

[lost matrix]

Tag me if you get an answer that doesnt involve core shaders plox

[torn shuttle]

I have a worse solution than shaders for what it's worth

but I didn't want to do it

well shit

[young knoll]

https://github.com/Godlander/lessfancypants

[sterile token]

Hypixel does it and they dont ask u for shaders

Atleast on the skyblock with the minions im totally sure they are modded armor stands

[torn shuttle]

yeah armor stands

the trick is player armor

[young knoll]

The minions have vanilla armor and a custom skull

[torn shuttle]

like I could maybe coerce a client into believing they are wearing horse armor with a custom model maybe

[young knoll]

Well if you glue some display entities to them

[torn shuttle]

desync

[young knoll]

Make them passengers

[torn shuttle]

if it's not worn by players it will look like garbage

lol

I am pretty sure that would be a war crime

holy shit I can't type today

[young knoll]

Well then your only option is shaders

[torn shuttle]

I mean not really

hrm

[lost matrix]

This looks fairly easy to use

[torn shuttle]

actually nvm

player armor isn't a discrete entity from the player right

so at best you could retexture, right

[young knoll]

Correct

[torn shuttle]

damn

[young knoll]

Mhm

Models are hardcoded for everything but the head slot

[torn shuttle]

mojang where is that modding api we were promised over a decade ago

or modding tools

[quaint mantle]

whats your opinions on the ytber code aesthetic

[lost matrix]

He has some very good points. But his videos are mostly about the basics for clean code.

I liked those the most

[eternal night]

rip the obviously most based take on the channel

delegation babyyyy

[torn shuttle]

the head slot still can't do jack shit with normal helmets right, the trick would be to put something else on there?

[young knoll]

I believe so, yeah

[torn shuttle]

ok I've never done it before, how hard would it be to send a packet telling a client they are wearing horse leather armor on their head every time they equip some other helmet

[young knoll]

Well there is a library for an armor equip event

[lost matrix]

https://www.youtube.com/watch?v=PCm5Gi0vMGA

This is the most based approach for the modulo operation

[quaint mantle]

I saw that

[torn shuttle]

there isn't a way to send that kind of fake behavior packet via the spigot api right

I think it's possible for blocks but not for armor?

[young knoll]

There is

[torn shuttle]

really now

[young knoll]

sendEquipmentChange

[torn shuttle]

hol' up, wait a minute

[lost matrix]

But this will only work for replacing the helmet. Not the entire armor.

[torn shuttle]

well that's 1/4

aka a passing grade

[young knoll]

Now I’m no math expert but…

Hello, i'm detecting an ItemDisplay with a raycast, this is working but is there a way to reduce the detecting box from the ItemDisplay ? I know there are no hitbox on ItemDisplays and TextDisplay but with this raycast the Displays box are way too large : ``` RayTraceResult rayTraceResult = player.getWorld().rayTrace(player.getEyeLocation(),player.getEyeLocation().getDirection(),20,FluidCollisionMode.ALWAYS,true,1,null);

[young knoll]

Low the ray size argument

I believe it’s the 1

[eternal oxide]

it is

[inner mulch]

does somebody know how i can turn of the auto uuid assigned by mongodb to every object (I'd like to set it to a uuid)

[noble lantern]

typically you can just override it with a mongo predicat iirc, i find it easier to do that one line of code

Though, why change _id? Couldnt you just add a uuid field? Typically changing the mongo _id isnt very favored and could cause issues, mainly just cause the entry to me re-indexed but thats about it

[inner mulch]

i will never use _id and this use up storage

[thin wind]

Thanks it is working, i thought 1 was already low enough

[noble lantern]

_id is used by mongodb for indexing

the space it takes up is also extremely negligable, its a line of JSON essentially no more than a few bytes

[inner mulch]

why shouldnt mongo be able to index it with a uuid of a player?

[noble lantern]

It does, if you add it as a field 😄

you can index by fields, but mongo by default uses _id to sort things out and index entries

[inner mulch]

bruchard on the topic of mongodb, is there a tut on how i can structure my database like a professional?

[young knoll]

It’s stored as bson

So it should be just about 16 bytes

[inner mulch]

ok

[noble lantern]

yeah not that bad for storage at all even with thousands

[noble lantern]

For mongo DB i just take my PlayerData class and serialize it to the DB

i find that the easiest solution when working with MongoDB

[inner mulch]

so you have 1 humongous class with all the data?

[noble lantern]

Well, i have a would different classes but essentially yeah

For example I would have mongo db for all these seperate types of objects:

PlayerData
ServerData
EventData

Etc. etc.

[white root]

Is there some built in way to get how close to being broken a block is?
e.g. when youre digging a piece of obsidian, if I had that Block as a vairable, how would I get what percentage broken it is?

[noble lantern]

sadly IIRC you just have to monitor it with packets, might be wrong here havent done something like that since 1.18, dunno what new stuff they added to the API

[white root]

damn, alright

[young knoll]

You can get how much progress the player makes per tick

But I don’t think you can get the overall progress

You could manually count tho

Via BlockDamageEvent and a scheduler

[vapid grove]

Which one is better
A:

PatternUi patt = this.newPattern(
    "pmpmempmp",
    "mwwwwwwwm",
    "pw wrwxwp",
    "mwnwbwwwm",
    "ampmpmpmp"
);

B:

PatternUi patt = this.newPattern(
    "p m p m e m p m p",
    "m w w w w w w w m",
    "p w - w r w x w p",
    "m w n w b w w w m",
    "a m p m p m p m p"
);

[white root]

I think B is more readable, imo. Probably that one if they both function the same

[vapid grove]

both do function the same

[glad prawn]

but B is more readable

[vapid grove]

yeah i thought so, i was more thinking if compactness or readability is better in this scenario

but either way

patt.addChar('m', mg);
            patt.addChar('p', pg);
            patt.addChar('w', wg);
            patt.addChar('e', enchant);
            patt.addChar('r', right);
            patt.addChar('x', bg);
            patt.addChar('n', info1);
            patt.addChar('b', book);
            patt.addChar('a', exit);

i need to figure out how to make this part better

cause this seems excessive

[young knoll]

You could make it chainable

Helps a bit ig

[vapid grove]

theres a way to make it chainable with 2 variables at a time?

i thought you can only do that with one

[young knoll]

Just return this for the method

patt.addChar().addChar().addChar() etc

[vapid grove]

oh i see what you mean

now i just gotta figure out how to get intellij to hide hints for variables

its annoying it makes it offset lmao

[eternal night]

Right click

[vapid grove]

thank you

[storm scaffold]

I've asked about this in the geyser server too, but I've gotten no response so far and I was wondering if this "LinkageError" could be a more general issue encountered with plugins - if so what could I be doing wrong that makes this happen?

[sterile token]

why spigot is destryoying the api that used to be?? Starting from the ids of things, api methods, conventions, java versions

[remote swallow]

item ids were removed from vanilla so they got removed

[sterile token]

that i can understand, but why java versions? there was no need to that they just make us losting time

[remote swallow]

bukkit uses java 8

or 9 idk if a pr for thats been merged yet

[sterile token]

hmn?

no

are you sure?

[remote swallow]

bukkit uses 8, spigot uses 17

[sterile token]

but why would you use bukkit for developing? its dead bukkit

[remote swallow]

spigot maintains bukkit

or a fork of bukkit

https://hub.spigotmc.org/stash/projects/SPIGOT/repos/bukkit/browse/pom.xml#17

[sterile token]

i mean spigot just destroying their amazin api

[storm scaffold]

sometimes I forget spigot is even a fork of bukkit lol I just forget bukkit exists

[sterile token]

it doesnt exists anymore that why haha

[vapid grove]

@young knoll ty folr the suggestion btw

PatternUi patt = this.newPattern(
    "p m p m e m p m p",
    "m w w w w w w w m",
    "p w - w r w x w p",
    "m w n w b w w w m",
    "a m p m p m p m p"
);
patt.addChar('m', mg).addChar('p', pg).addChar('w', wg).addChar('e', enchant).addChar('r', right)
    .addChar('x', bg).addChar('n', info1).addChar('b', book).addChar('a', exit).applyPatt();

[young knoll]

Spigot I think is still java 8? Idk

[remote swallow]

spigot is technicalyl a fork of craftbukkit

[remote swallow]

i thought spigot needed 17

[young knoll]

The server is java 17 though so that’s what you gotta use

[sterile token]

where is Java 8? Only version 1.7x and 1.8x use JAva 8

[remote swallow]

no

everything up to 1.16.4 can use 8 or 11

[sterile token]

then spigot did a fucking mess

[young knoll]

Like I said

[sterile token]

because you need thosens of versions for running the server, with no need

[remote swallow]

i just checked, turns out spigot doesnt care about version it wants 8

[young knoll]

Minecraft moved to java 17

[remote swallow]

its mojang that update to new versions

[young knoll]

So you gotta use 17

[sterile token]

oh lmao i forgot that spigot uses native mojang server code

[young knoll]

You can still develop with 8 but why would you when the server uses 17

[tender shard]

spigot-api is java 8

[sterile token]

Java 17 is same java with some shity additions

thats why i complain

[young knoll]

I think you mean good additions

Instanceof pattern matching my beloved

[sterile token]

because most teams do weird things to their products that were okay, without need to change it!!

[remote swallow]

spigot retains compat as much as possible

everything you can do in 1.8 you can still do now with much more features

[tender shard]

Yeah literally nothing in the API was ever changed or broken except removing item ids which were already deprecated in 1.8 lmao

[sterile token]

ik that, but without need. Because that why exists libraries too from a view its really unncesary changes

[remote swallow]

so we shouldnt have added new events, pdc, better api and that

[tender shard]

You are free to use a 8 year old api version

[remote swallow]

it should be up to all 30 plugins you have to shade a library for it?

[tender shard]

It will still work on 1.20

[sterile token]

yeah as i said many times this the reason of being 1.8 dev

From 1.13 up all is broken and creappy to use haha

[remote swallow]

its not tho

the api now is much easier to use

i dont need to remember 20 trillion id magic values

[tender shard]

Sssh he‘s just drunk

[remote swallow]

yeah

its been a while since this happened while i was here

[sterile token]

lmao, im being serious

[tender shard]

Me too

[quiet ice]

You should go to bed

It's late and tomorrow is a whole new day

[tender shard]

Give me one example of whats worse in 1.20 api than in 1.8 api verano

Just one

[sterile token]

im talking clearly and without saying weird things. Im just complaining about spigot doing weird changes to the api and even the versions

[tender shard]

For example?

[young knoll]

I have an idea

Let’s remove all the string methods

https://cdn.discordapp.com/emojis/1017515898870956154.gif?size=48&name=pepe_laugh&quality=lossless

NMS momment

[tender shard]

Nms is not api bro

[slender elbow]

lol

[sterile token]

.

[young knoll]

Also we having mappings now

[tender shard]

Only paper deprecated them

Not spigot

[young knoll]

Which make NMS way better

[tender shard]

And paper also didnt remove them

[sterile token]

okay, so mappings are the docs that exists on java for a long time

[remote swallow]

no

[tender shard]

What

[young knoll]

NMS doesn’t get docs

It’s not api

[remote swallow]

mappings convert a.b.c(xyz) to player.connection.send(value)

[sterile token]

i know NMS are reflections over obfuscated code, isnt that?

[quaint mantle]

guys

how do I even name this

public final class Level1To9Wrapper implements LevelWrapper {

    @Override
    public @NotNull ChatColor getLevelColor() {
        return ChatColor.GRAY;
    }

    @Override
    public int getRequiredExperience() {
        return 15;
    }

}```

[remote swallow]

verano you need to go to bed

[sterile token]

no need for being rude, i never used NMS because i dont had the necessity atleast to what i code

[tender shard]

You‘re also not using spigot if you think string methods were removed

[young knoll]

NMS is just the internal server code

[sterile token]

okay, so reflections over the obfuscated

[young knoll]

Technically the name NMS isn’t accurate anymore but whatever

[hallow lion]

It is impossible to work with anvil inventories via only the spigot api without using nms/packets. Are there plans on having more support for it?

[eternal oxide]

no

[slender elbow]

NMS deez nuts

[young knoll]

There’s a large inventory PR in progress

[sterile token]

right, sorry for this. But i want to understand

[hallow lion]

can i get a link?

[remote swallow]

im not trying to be rude, but you really need to sleep

[remote swallow]

have you signed the cla?

[hallow lion]

don't know what that is so no

[young knoll]

Well then you won’t be able to see it

But here ya go

https://hub.spigotmc.org/stash/projects/SPIGOT/repos/bukkit/pull-requests/926/overview

[remote swallow]

you can see the actual repo its on

https://hub.spigotmc.org/stash/users/y2k_/repos/bukkit/browse?at=container-api

[hallow lion]

would this add more support for custom anvil inventories and such?

and any eta on that?

[young knoll]

It should

And no, no eta

You can do anvil GUIs with just NMS and no packet wizardry

But yeah still not ideal

[tender shard]

is that supposed to reflect the XP amount required in vanilla to level up?

[quaint mantle]

no

custom leveling system

[young knoll]

You technically could just use a pair/map.entry/whatever people like to call it

[storm scaffold]

Anyone know what I'm doing wrong here? I still can't figure it out

[quaint mantle]

well

maybe these levels will have some other

attributes

[young knoll]

You could also just have a holder class

[quaint mantle]

wdym

[young knoll]

That holds the stuff as variables

new LevelData(ChatColor.GRAY, 15)

Etc

[quaint mantle]

idk I thought about that

[young knoll]

Perfect use for records if ur on modern java

[quaint mantle]

yeah ill prob do that

[vapid grove]

Why not skip this and just use a math equation for this
And for the color just do checks or smth to see what color it should be

[quaint mantle]

well it's a remake and idrk the actual equation

[vapid grove]

xpRequired = level * 15 idk

[quaint mantle]

nah its so random lo

[young knoll]

Im sure you could do it as a single equation

But it would get messy very quickly

[quaint mantle]

15 to 30 to 50 to 75 to 125 to 300

to 600 to 800

[vapid grove]

oh its manaul by the level

[quaint mantle]

to 900

[vapid grove]

thats really strange tbh

[young knoll]

Alternatively have a massive config file for it

Kek

[quaint mantle]

lmfao

I might make everything configurable last cause that sounds like a pain rn

[vapid grove]

what i do is

XP(L) = 15 x 2^(L-1) for example

so level 1 starts at 15

then for example: 15 x 2^(2-1) (level is 2)
would be 30

[quaint mantle]

well I personally think this is a waste of time cause the gamemode maxes out at level 120

[quaint mantle]

and the prestiges is what continues

[vapid grove]

i guess? just seems like a waste of time to create a massive config file for a task that can easially be done w/ math

and in my personal oppinion creating a massive config file for something like that is insanely overkill, but ehh to each their own

[noble lantern]

wait what

Level1To9Wrapper?

[young knoll]

You could just have a configurable formula

[noble lantern]

Did you make 120 classes?

[young knoll]

Using something like crunch

[vapid grove]

from what i can tell yes

[noble lantern]

wellp ive officially seen it all

[young knoll]

No that’s 1 to 9

So presumably he made 12 classes

[noble lantern]

even then just math with like a

baseXp & scalePerLevel (% increase from base) would be perfect

[vapid grove]

wait i just realized these are seperate classes

[noble lantern]

XDD

[vapid grove]

i was under the assumption of oh maybe he embeded the classes inside his level wrapper?

[young knoll]

Yeah idk why they didn’t do a single record

[vapid grove]

like a static class or smth but

jess

[vapid grove]

or go braindead basic

xp = level * 15

[noble lantern]

that oto but i likey the percentage based equation, but that would also work too

[young knoll]

xp = 1000 * 1.01 ^ level

[vapid grove]

thats true

[young knoll]

I think McMMOs default formula is like 1000 + level * 20 or something

[vapid grove]

whenever i do equations like this i forget bedmas and go overkill with parentheses

so it looks like the stupidest thing ever

[young knoll]

Kek

[vapid grove]

also aaaa nobodys been able to fix my verification status

im stuck as an unverified for enternity

[wet breach]

Except computers dont operate like this

What people forget in the order of operations is that both division and multiplication are treated with same priority. That means regardless which is first that is the one that will be operated on. Same goes for addition and subtraction.

This is why parenthesis become important or screw your equation all together

[young knoll]

That’s on them for forgetting

[wet breach]

Lol

[vapid grove]

oh so im doing correctly accidentally anyways

mission failed successfully

[torn shuttle]

day 10 of making a wiki website: I built in a sign system into the website to display exactly 3 signs. This is because I am tired and did not want to have to boot minecraft

also manaspace is a really nice pixel font

[waxen plinth]

I tend to prefer computing the result in multiple steps using multiple variables if it needs more than one parenthetical expression

[torn shuttle]

which is all fine and good until you're computing enough data that the overhead from the garbage collector for all of your variables becomes a problem

[waxen plinth]

you really don't need to worry about that

there is really no additional overhead to the garbage collector for this in most cases

[torn shuttle]

🥲

yeah about that

[waxen plinth]

especially because in all likelihood the compiler is going to inline it if it would make a difference

all this just reminds me why I don't use java anymore though :)

[torn shuttle]

I do wish java were smarter about early collection of scoped variables or at the very least give me an easy tool to handle that myself

we already have boolean and Boolean but have you heard about bBoolean where you can just tell java to bBoolean.kill()

[quaint mantle]

How do I obtain all the net.md_5.bungee.api.connection.Server in the network?

[torn shuttle]

not to confuse with BBoolean which is a thread safe boolean

or bBBoolean which is a thread-safe boolean you can manually deallocate from memory

or BBBoolean which is a boolean with 4 possible states, true, false, null and maybe

[waxen plinth]

ok but the reason I say this doesn't matter is because I mostly use it in mathematical expressions

which generally use primitives

not subject to gc in the first place

and even if you do use objects, storing additional references to the object really doesn't do anything to gc

if java uses a reference counting gc then the only cost is decrementing the reference count when it goes out of scope, which is negligible

and if not then there is no gc cost to having more variables

gc runtime scales with allocations and stack references are about the most irrelevant thing to it

because unless the gc pause happens while your function is running, it's just some references that will be dropped almost immediately anyways

and if the gc pause happens while your function is running, oh no, it has to count one more reference

I really can't think of a situation where this would make any meaningful difference in execution time but I would be happy to see a benchmark showing otherwise

[torn shuttle]

more than anything else at a scale you might be running the gc more and more often

and the gc itself is not necessarily to smoothest experience on a live server, it doesn't have to be bad necessarily but it can be

even though the tick rate of minecraft is relatively low

[slender elbow]

eh, modern GCs can easily clean up several dozens and hundreds of GBs like it's nothing

given appropriate tuning, but even for a Minecraft server the defaults are more than fine

[torn shuttle]

yeah it's not a huge problem, rarely it will run at a particularly bad time and that's when you spot it

[slender elbow]

it's interesting, in some code that I wrote recently the hottest function created a new Interval(min, max) up to 6 times at most, and it was severely impacting the performance of the function, upon profiling nothing seemed out of the ordinary, and GC contention eas not a problem, but the constant "using min/max that are jumping around all over heap" was, which obviously something like that does not show up in a profiler

can't wait for Valhalla praying rn

[torn shuttle]

accurately profiling plugins is just not even a thing

[slender elbow]

that single change cut the entire run-time by, like, 60%

[torn shuttle]

there are so many things that just melt into the background noise

[slender elbow]

help why is waitUntilNextTick taking 70% of my tick time :^)

[wet breach]

If you use mostly primitives. However if autoboxing occurs it doesnt stay a primitive

[waxen plinth]

ok but who is writing Integer i = ... lol

I feel like you're next going to say "but it might come from a function returning Integer"

at which point I am going to say "but I'm only talking about local variables affecting gc"

I swear I can't even give a simple suggestion like "I like to split my complex expressions across multiple lines" without people bikeshedding about the most micro of microoptimizations

[young knoll]

You should talk to Marco

He loves micro optimizations

[wet breach]

It depends how your equation is written and whether or not you mix types. So you can end up with things being intrinsically turned into Integer.valueOf(). But the final output still be a primitive. But now we just made objects out of nowhere which can and sometimes hurt gc and cache related things

So in regards to splitting your equation. That actually might be more optimal in some cases

[quaint mantle]

    @Override
    public List<String> onTabComplete(CommandSender commandSender, Command command, String s, String[] strings) {
        if (commandSender instanceof Player) {
            if (strings.length == 1) {
                List<String> completions = new ArrayList<>();
                completions.add("arg1");
                completions.add("arg2");
                completions.add("arg3");
                return completions;
            }
        }
        return null;
    }```

is this wrong ?

tabcompleters not working

[river oracle]

Did you register it

[quaint mantle]

yes

getCommand("test").setTabCompleter(new Komut());

plugin.yml:

  test:
    description: My custom command
    usage: /test <arg1>```

[river oracle]

Ahhh I see your mistake switch args to 0 and give it a whirl I'm pretty sure it's 1 less than you expect for the tab completes could be wrong but prey sure that's it

[quaint mantle]

aight

nah still not worked 😢

[river oracle]

🤷‍♂️

[young knoll]

Try setting the executor

[quaint mantle]

i will change my spigot version

[young knoll]

Tbh I’ve never used just setTabCompleter

[quaint mantle]

oke

[vapid grove]

me neither

[river oracle]

Completed might not work without executor tbh

I'd need to take a look at internals but I wouldn't be surprised

[vapid grove]

i do this personally

public abstract static class CommandBase {
        protected String key;

        /**
         * Generates a CommandBase for a Command.
         *
         * @param key The key/name for the command.
         */
        public CommandBase(String key) {
            this.key = key;
        }

        public abstract boolean onCommandRan(@NotNull CommandSender sender, Command command, @NotNull String alias, @NotNull String[] args);

        public abstract List<String> onTabRan(@NotNull CommandSender sender, Command command, @NotNull String alias, @NotNull String[] args);
    }

and then i have a manager for it

[river oracle]

TabExecutor ftw

[vapid grove]

how do you guys do guis btw

i feel like mines kinda

bad :/

[river oracle]

https://github.com/PineappleDevelopmentGroup/Pineapple

Check the dev branch in the core module

Has my gui stuff

[young knoll]

Your nerd system with slots

:p

[vapid grove]

I made my own framework that I use, and it works well, im just curious how people directly create their guis
are people using managers, or are people just making a class and calling it whenever

for example heres mine

https://paste.md-5.net/qigalovapo.coffeescript

[river oracle]

Mine maps towards more what internal NMS looks like for inventories barring a few methods that aren't exposed by API

I am the inventory pr guy after all @young knoll can vouch

[vapid grove]

I believe it lmao

I wanna improve as much as possible with creating stuff like this personally so its better for me just to straight up ask

right now how my managment of stuff works is:

The manager that manages all the sub-managers < Sub-managers (like custom enchants, items, ect) < The objects inside those sub managers (like the custom item self)

Its weird but it works pretty well

[river oracle]

I've always wanted to make an inventory and command framework in Lua

[vapid grove]

I actually do lua mainly

I do coding jobs on roblox XD

I started on lua when I was 10-11?

[river oracle]

Lua is a gross language but it's a joke to embed

[vapid grove]

I would code rp games n such

[vapid grove]

Its the most barebones basic language

[young knoll]

LUA would be an alright scripting language

[vapid grove]

Im trying to do java as my main language cause I love OOP

[young knoll]

Probably still not as accessible as skript tho

[river oracle]

OOP is also disgusting

[vapid grove]

:(

[young knoll]

Man is a functional pleb

[river oracle]

No functional is literally just people who don't want to admit objects can be useful

[young knoll]

What’s the other option

[river oracle]

Don't affiliate fully with one?

[young knoll]

Oh right just punch raw binary into the machine

[river oracle]

And don't code pure oop or pure functional

Do what fits the bill

[vapid grove]

Thats pretty much what I did with Lua

[river oracle]

Well Lua can't actually code OOP as OOP wants you to

[young knoll]

I wonder how much binary it would take to write a basic functional program

[vapid grove]

you can use modules with lua

which is kinda like oop

but more basic

[vapid grove]

you should try lmao

see how long it takes

[young knoll]

Y2k is the embedded systems nerd

[river oracle]

I mean reminder that java.util.function is technically functional programming and using it deviates from oop

[young knoll]

😩

[river oracle]

Ofc java is missing quite a few things from functional programming but still going pure OOP kinda sucks also If you were to follow SOLID your code base would end up the size of New York city

Don't get me started on those DI nerds

[river oracle]

Fr though it's much better than arguing about which of the 20 billion java script frameworks I'm going to use for my next website

[young knoll]

Lol

[vapid grove]

Genuinely never knew that existed

Then again currently I do not have a use for that specifically

[river oracle]

It's extremely useful

10,000%

[vapid grove]

Any good tutorials online on how to use it?

Id love to find some usages for it within my servers plugin

Or is it literally just

Like coding functional

[young knoll]

It’s an object that can represent a basic function

[vapid grove]

Oh I see

[river oracle]

https://www.baeldung.com/java-functional-programming baeldung is usually pretty decent but it'll take time

[quaint mantle]

guys i try tabcompleter on 1.18.2 and worked

tab completers not working on 1.16.5 ?

[river oracle]

Guess not legacy problems ftw

[young knoll]

When the out is dated

[vapid grove]

If its deprecated or legacy probably dont use it

just perhaps

[quaint mantle]

😦

[vapid grove]

why are you using legacy stuff btw

i never even heard of that til a couple mins ago cause ive always used onTabComplete

[quaint mantle]

My market is at 1.16.5

[vapid grove]

So why not change the code to function in newer versions

[river oracle]

Worlds smallest market

Hey everyone's gotta have their niche

[young knoll]

They are using onTabComplete

[white root]

Hey, im probably just stupid or something

But what does package-private mean, and why does tying to use EntityType#getTranslationKey() make intellij tell me: "Cannot access 'getTranslationKey': it is package-private in 'EntityType'"

[vapid grove]

wait then am i dumb

is onTabComplete outdated?

[river oracle]

?jd-s

[undone axle]

https://hub.spigotmc.org/javadocs/spigot

[vapid grove]

private means it can only be accessed within the class

[quaint mantle]

well i will use new version

[young knoll]

No

[river oracle]

Should be public maybe a kotlin issue?

[white root]

yeah, im familiar with private, just not package-private

[river oracle]

If you're using paper maybe they removed it

[quaint mantle]

u guys any idea for tabcomplater without command ?

[vapid grove]

wdym without a command

[white root]

I am indeed building against paper

[vapid grove]

like are you creating a searchbar?

[river oracle]

Then this isn't the place to be asking as far as spigot is concerned this method is public

[quaint mantle]

well 1m i will show

[young knoll]

Paper probably has another method for it

[vapid grove]

ok speaking of is there any active forumn staff i can dm about my verification issue lmao

[river oracle]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/entity/EntityType.html#getTranslationKey()

[young knoll]

Probably translationKey() or something

[river oracle]

Email support

?support

[undone axle]

[e-mail]

[river oracle]

Md can probs helps 😌 👌 💯

[vapid grove]

alr i shall send a email

[quaint mantle]

coll was give me a docs

for that

but docs didnt explain me

[vapid grove]

oh

[river oracle]

Isn't there an event to be used for that

[young knoll]

Nah it’s just a method

player.setCustomChatCompletions or something

[quaint mantle]

In which event should I use this?

[young knoll]

Player join probably works fine

[quaint mantle]

i will try something

[quaint mantle]

is this for latests version ?

[river oracle]

Most be smh missing out in all that great new api

[vapid grove]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/event/player/PlayerChatTabCompleteEvent.html

I think thats it?

Its deprecated however

[quaint mantle]

omg yes

[river oracle]

It doesn't fire anymore

[quaint mantle]

for 1.20

[vapid grove]

Deprecated.
This event is no longer fired due to client changes

it wont work however

[worldly ingot]

You might actually have to delay it by a tick

I'm unsure if the player's connection is fully ready in the join event just yet

[young knoll]

PlayerJoinedEvent when

[dry forum]

does anyonme know why no particles are being spawned

        double minX = Math.min(location1.getX(), location2.getX());
        double minY = Math.min(location1.getY(), location2.getY());
        double minZ = Math.min(location1.getZ(), location2.getZ());

        double maxX = Math.max(location1.getX(), location2.getX());
        double maxY = Math.max(location1.getY(), location2.getY());
        double maxZ = Math.max(location1.getZ(), location2.getZ());

        for (double x = minX; x <= maxX; x += 0.1) {
            for (double y = minY; y <= maxY; y += 0.1) {
                for (double z = minZ; z <= maxZ; z += 0.1) {
                    spawnParticle(player, x, y, z, 0, 0, 0, 0, particleCount);
                }
            }
        }
    }

    private static void spawnParticle(Player player, double x, double y, double z,
                                      float offsetX, float offsetY, float offsetZ, float speed, int count) {
        PacketPlayOutWorldParticles packet = new PacketPlayOutWorldParticles(Particles.E,
                true, (float) x, (float) y, (float) z, offsetX, offsetY, offsetZ, speed, count);

        ((CraftPlayer) player).getHandle().c.a(packet);
    }```

```        Player player = (Player) commandSender;
        Location location = player.getLocation();


        spawnParticleBox(player, location, location.clone().add(10, 10, 10), 20);```

its supose to spawn particles in a box between 2 points

[young knoll]

What kind of old version are you on
