[spiral light]

if this was in the api and i used all the years split and so on for this i would explode 😄

[hardy swan]

Try see which is the one giving the null value

I assume this is line 33?

yea then before that line executes try finding out which step gave that null

is it p? p.getWorld()?

did you execute it using console? lol

[humble prairie]

Does anyone know how i can place a log that is looking sideways? Every log that my script places is looking upwards

[crimson verge]

don't know crap about script, can only help ya if you're coding with Java and spigot lol

[tardy delta]

how people dare to use script

and come here

[crimson verge]

lmfao

[hardy swan]

is there a method in java that allow you to run c code

[sacred mountain]

doubt it lol

[vocal cloud]

Yes it's called don't

[crimson verge]

sounds like a mess waiting to happen lmao

[tardy delta]

wasnt there a way to execute JS code tho?

[vocal cloud]

Yes java has a native JS reader boi

[tardy delta]

i thought i saw it somewhere

[vocal cloud]

This
https://www.oracle.com/technical-resources/articles/java/jf14-nashorn.html

[tardy delta]

oh yes that

[hardy swan]

oh JNI was what i was looking for

and the native keyword

[tardy delta]

if you want to execute it directly from java code hmm

[hardy swan]

no thanks, just wanted to know

haha

[paper viper]

you cant execute C code directly

you can however, call methods from C shared libraries

(dll on windows, dylib on mac, so on linux)

[ivory sleet]

pulsebeat C enthusiast 😮

[paper viper]

i wish

[ivory sleet]

lol

[hardy swan]

yea, that's what i meant when I say run C code hahaha

[quaint mantle]

It is deprecated though

[quiet ice]

I think it is actually no longer available on newer Java versions

[vocal cloud]

Yeah I imagine it's kinda useless lul

and probably a huge vulnerability

[hardy swan]

Nashorn4j exploit

[quaint mantle]

GraalJS good

Welp, it is not too bad for scripting engines

[feral egret]

How can I save a hashmap and load it back in on reload?

[tardy delta]

save it to a file

depending on what kind of data

[feral egret]

public static Map<String, Integer> playerIDs = new HashMap<>();

That's the hashmap that I wanna store, I've tried in-built bukkit methods and looked up docs for the past 3 hrs but I can't find anything on it

[tardy delta]

loop over the map

i kinda forgot how to save a map

[feral egret]

I don't know how to save in the first place tho 😢

[tardy delta]

ah like this

https://youtu.be/XVfAt65UTgc

i like Map#forEach with (key, value) -> more

[feral egret]

I'll watch that vid again, I watched it earlier but couldn't get it working but I'll try again

[tardy delta]

its maybe not the best way

[feral egret]

I got the read part working but not the write part

[tardy delta]

the writing part isnt difficult as you work with primitives

[quiet ice]

Well, wrappers of primitives

[tardy delta]

well they both arent

true

easier than like itemstacks

but what does that data represent?

[quiet ice]

Also, I personally prefer DataOutputStream if you don't need it to be writable by a human. Saves on a lot of memory overhead imposed by yaml parsing

[tardy delta]

maybe saving it in the PersistentDataContainer would work tho

if it makes sense

[feral egret]

And will it auto save to config.yml?

[tardy delta]

you have to call the code if you want

also fileConfiguration.save(file)

[quiet ice]

Something like this would basically be

try (DataOutputStream out = new DataOutputStream(new FileOutputStream(new File(getDataFolder(), "ids.dat")))) {
    out.writeInt(playerIDs.size());
    for (Map.Entry<String, Integer> entry : playerIDs.entrySet()) {
       out.writeUTF(entry.getKey());
       out.writeInt(entry.getValue());
    }
} catch (IOException e) {
    throw new RuntimeException(e);
}

[tardy delta]

or just use the fileconfig api

[quiet ice]

Reading would be

try (DataInputStream in = new DataInputStream(new FileInputStream(new File(getDataFolder(), "ids.dat")))) {
    int size = in.readInt();
    if (playerIDs == null) {
       playerIDs = new HashMap(size);
    } else {
       playerIDs.clear();
    }
    for (int i = 0; i < size; i++) {
        playerIDs.put(in.readUTF(), in.readInt());
    }
} catch (IOException e) {
    throw new RuntimeException(e);
}

See, much nicer and far more compact on memory!

[tardy delta]

finally someone who uses try with resources :D

[tender shard]

Anyone know how I can get an NMS ComposterBlock from a regular BukkitBlock?

((CraftBlock)bukkitBLock).getHandle() returns a LevelAccessor

I need an NMS block though

[tardy delta]

if doing a calculation with an Integer object, it will call .intValue() right?

[tender shard]

Found it out:

Block nmsBlock = ((CraftBlock)block).getNMS().getBlock();

[quiet ice]

For anything but ==, yes

[tardy delta]

ah right

its weird that you cant just do like a Dictionary<string, int> in c#

with primitives

[quaint mantle]

it is automatically unboxed though

[tardy delta]

yea

[quaint mantle]

because primitives does not extend object

[tardy delta]

and something that extends object is required

[quaint mantle]

But it probably will be possible in next java versions

yep; thats the generics contract

[tardy delta]

its possible in dotnet :D

ah i get it like <T extends Object>

[brave sparrow]

It’s required because the compiler removes the <T> and replaces it with just Object types

[glossy venture]

Bukkit.getServer().getServicesManager().register(Permission.class, instance, pl, ServicePriority.Highest);

is this the correct way to implement a vault service

[brave sparrow]

The generics are for compile time type checking

And automatic casting

[brave sparrow]

You don’t have to explicitly require it to extend Object, any class always extends from Object automatically

[tardy delta]

or just <?>

[quaint mantle]

yeah, and, and in the future primitives will extend Object aswell, objects will be as fast as primitives

[brave sparrow]

Right, I’m merely stating why it’s different from other languages

[tardy delta]

oh

[brave sparrow]

For example, in C++ the template system compiles a separate version of the templated class for each “type”

[quaint mantle]

Fastutil will became useless

[brave sparrow]

So if my program uses vector<int>, vector<ClassA> and vector<ClassB>, the compiler is going to compile 3 versions of vector, with all the templates changed to each type respectively

In Java we instead compile just one, and replace everything with Object

[tardy delta]

so its much easier for the compiler?

[quaint mantle]

Ah, thats similar to how fastutil works

Int2Object Map, Long2DoubleMap, Char2ShortMap...

[glossy venture]

anyone? i cant really test it because the plugin is large but there are still fundamental parts missing so i cant really run it

[quaint mantle]

Thats where modularity starts helping

[glossy venture]

it depends on the whole plugin

[quaint mantle]

Mock some parts

[glossy venture]

ok i looked at vault source thats how they do it so thats how i will do it

[quiet ice]

yep, that is the correct way to do it

[sterile token]

A secure way of saving private credentials on plugins?

[vocal cloud]

https://www.baeldung.com/java-password-hashing

[sterile token]

Properties file can be read as txt, json or yaml files?
Or they save content like hash/with protection

[trim surge]

• Developer & Technician
• Java, and others``` 
🤔

[trail dragon]

Is there an event that can detect if a players armour breaks?

[tardy delta]

itembreakevent? is there one?

[sterile token]

The problem is that i need to save on my plugin an api key from my website

[quiet ice]

what credential?

[trail dragon]

There is that, but it seems to only be for items, not armour

[tardy delta]

armour is an item ._.

[quiet ice]

What does this api key do?

[crimson verge]

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

[sterile token]

its used to hash the plugin data (name, version) sent to my api

[quiet ice]

You should limit its powers as much as possible, there is no real way to store it "safely"

[sterile token]

Properties file can be read as txt, json or yaml files?
Or they save content like hash/with protection

[trail dragon]

Ah okay, and then I just check the item that has just broken to see if it is (for example) a netherite chestplate?

[crimson verge]

ye

getBrokenItem()

and go from there

[trail dragon]

ahhhhh

right thank you!!!

[crimson verge]

np!

[quiet ice]

If you are really paranoid about it, use JNI and use the API key there. As soon as it gets into the JVM you are out of luck

[sterile token]

Its a mc plugin

I cannot use JNI

[quiet ice]

You can as far as I know

[sterile token]

Lol really?

[quiet ice]

You might not be able to publish it to spigotmc though

[vocal cloud]

I mean you're API key is only as secure as the system it's running on. Once you load it it's in memory

[quiet ice]

If the damage of having the API key published publicly is next to nil, do not bother. To limit damage you can e.g. have a 1 key per jar type of thing

Plus having any protection on anything will just pull attention towards it.

[sterile token]

Its for MCM, there you can do what ever for example your plugins can be heavly obfuscted and depend from intertnet

Ah you make reference to having 1 key hash each plugin let say

Thanks

[quiet ice]

No, 1 key hash each download/user. Would require dedicated infrastructure, but possible

[sterile token]

Im between NodeJS RestAPI or C# Websocket

I have seen that from java you can execute C# methods

So i will think a trick

[left swift]

When i use remmapped mojang spigot nms i have that error, why? maybe my maven md-5 plugin is wrong configuredfix Caused by: java.lang.ClassNotFoundException: net.minecraft.world.entity.EntityType$EntityFactory at org.bukkit.plugin.java.PluginClassLoader.loadClass0(PluginClassLoader.java:147) ~[spigot-api-1.18.1-R0.1-SNAPSHOT.jar:?] at org.bukkit.plugin.java.PluginClassLoader.loadClass(PluginClassLoader.java:99) ~[spigot-api-1.18.1-R0.1-SNAPSHOT.jar:?] at java.lang.ClassLoader.loadClass(ClassLoader.java:520) ~[?:?] ... 12 more

But thanks

[trail dragon]

hm @crimson verge how would I fix this?

Operator '==' cannot be applied to 'org.bukkit.inventory.ItemStack', 'java.lang.String'

if(p.hasPermission("test.playing") && e.getBrokenItem()=="NETHERITE_BOOTS"){

[hasty prawn]

e.getBrokenItem()=="NETHERITE_BOOTS"

Those can never be the same thing

[crimson verge]

Material.NETHERITE_BOOTS

[hasty prawn]

^

[trail dragon]

ahh okay thank you

[hasty prawn]

And use getType() on the ItemStack

[crimson verge]

^^

[quiet ice]

Where the hell did you find this thing

[trail dragon]

righttt

[quiet ice]

That's Java 5 javadocs or something

what does this error mean?

[sterile token]

No matter i use Java 1.8

Btww

😂

I will definitly make a library for this new project

If not i would have amazing headaches

[left swift]

any ideas?

[trail dragon]

Hold on, so you mean e.getBrokenItem().getType(), sorry if im being stupid, just trying to get to grips with this

[hasty prawn]

Yes

[spiral light]

did you run buildtools with remapped cmd ?

[left swift]

yeah

[coarse shadow]

how do i set a persistent data from config

[trail dragon]

hm, there still seems to be the same error

this is my code
e.getBrokenItem().getType()=="Material.NETHERITE_BOOTS"

[crimson verge]

remove the "

[hasty prawn]

^^

[trail dragon]

okay

[hasty prawn]

What are you trying to do

[trail dragon]

ah! that works thank you very much <33

[crimson verge]

always down to help haha

[indigo cave]

compiling

[hasty prawn]

?paste the code

[undone axle]

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

[left swift]

but here i copy and paste this plug from spigot forum. md-5 wrote this on 1.18, so I'm adding .1 in that to have 1.18.1, idk is that ok? should I change anything else?

[spiral light]

cant see something there but you also need to run buildtools once with -remapped flag or smth

and also the 1.18.1 version

[left swift]

i did it

[spiral light]

hmmm reloaded pom ?

[left swift]

i did it too, i dont have any errors

in pom

[quaint mantle]

is there any event to cancel when dragon breaks blocks

[crimson verge]

block break event you can get who broke it

and cancel if it was dragn

[hasty prawn]

Livvy you type too damn fast, you've answered before I even read it

[quaint mantle]

i tried that but doesnt work

[crimson verge]

coding hand heheheh

[mental sapphire]

import net.md_5.bungee.api.ChatColor;

Error is: The type net.md_5.bungee.api.ChatColor is not accessible
This isn't working for me, I'm not exactly sure why. I've tried a few things but haven't gotten it to work. Any ideas?

[crimson verge]

my b you want https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/entity/EntityChangeBlockEvent.html @quaint mantle

[spiral light]

hmmmm dont know ... had also some problems and somehow it worked with just trying some stuff

[crimson verge]

blockbreak is only players lol

[left swift]

r u using 1.18.1?

[spiral light]

yes

[left swift]

and can u show that plugin in pom?

[crimson verge]

no worries :)

[mental sapphire]

I have the api as a referenced library

[hasty prawn]

Could you send a screenshot of the error?

[crimson verge]

i think you want to import import org.bukkit.ChatColor; instead

[hasty prawn]

They still should be able to access the bungee ChatColor, expecially because I think it's required for working with components.

[crimson verge]

oh somehow i completely missed the bungee part lmfao

[mental sapphire]

I can't send a screenshot here, should I just dm it to you?

[hasty prawn]

You should verify so you can send screenshots 😄

[left swift]

🤦‍♂️ I didn't build with maven

[spiral light]

😄

[crimson verge]

it happens xD

[hasty prawn]

[left swift]

btw, why i have nosuchfieldexception here?

final Field suppliers = DefaultAttributes.class.getDeclaredField("SUPPLIERS");```

[hasty prawn]

Because it's remapped to b

[hasty prawn]

Weird. Can you send a screenshot of what library you're adding? Also try restarting Eclipse.

[left swift]

so i must use obfuscated names?

[hasty prawn]

If you're using reflection you do

[left swift]

hmm, ok

[glossy marsh]

Hello!
I've got a fairly obscure question; I want to add a new custom enchantment which is a curse. This is because the grindstone in Minecraft can remove enchantments but not curses from items. There used to be a function isCursed(), but it is now deprecated. I'm wondering how the grindstone checks if an enchantment is a curse, because it doesn't seem possible to give an enchantment a special "curse" attribute.

Alternate question: How do I make a new enchantment that can't be removed by the grindstine (same behaviour as curses).

[left swift]

and when i use remapped mojang, when i build using maven and i want to use plugin on the server i should use that normal file (xEntities-2022-01-13 21.09 i mean that :D)

[spiral light]

-remapped iirc

[hasty prawn]

I actually have an Enchantment API that can do all of that, if you're interested https://github.com/Dessie0/DessieLib/tree/master/enchantment-api

(Also isCursed() isn't deprecated afaik?)

[crimson verge]

it is sadly

[glossy marsh]

Or is there a way to add an enchantment glow to an item that can't be removed by a grindstone?

[glossy marsh]

Thank you Dessie! I will look into this! 🙂

[hasty prawn]

I mean it's deprecated but still works

[crimson verge]

you would want to look for the enchantment you added everytime someone uses the grindstone and cancel it if it is your "curse"

but im sure dessie's is much easier

also yes it does still work deprecated lol

[left swift]

then the server will know what to do? because in this file I will be renamed if I'm not mistaken.

[spiral light]

yes

[crimson verge]

but i dont believe you can make a new item cursed

[hasty prawn]

Mine is quite literally just calling setCanRemoveWithGrindstone(false); lol

[crimson verge]

oh yeah go with that then LMAo

copying that link for later dev use 😆

[hasty prawn]

there's a few APIs in there that are useful and they're all somewhat documented lol

[mental sapphire]

Okay it seems the error only happens when i'm specifically using bungeecord.jar, so i've removed it from the build path and there is a new error (which I think is why I tried adding it in the first place)

[crimson verge]

[vocal cloud]

Ah eclipse what a rare sight

[hasty prawn]

That looks like Eclipse being dumb and trying to import literally net LMAO

[crimson verge]

eclipse is big dum

[quaint mantle]

Friendly reminder that custom enchantments are unsupported

[hasty prawn]

Reimport it

[crimson verge]

but yeah spigot includes bungee stuff lol

[hasty prawn]

What are you even talking about

[quaint mantle]

sorry new messages didnt load

[mental sapphire]

When I try to auto import it the only option is org.bukkit.ChatColor, it doesn't seem to see the bungee one

[hasty prawn]

Where did you get that jar file

[crimson verge]

[hasty prawn]

The spigot-api-1.17.1 one

[hasty prawn]

Are you enjoying your newfound ability to use external emotes?

[crimson verge]

very much so

i took one of my boosts from my home server for this i gotta make it worth it heheh

[mental sapphire]

I got it from buildtools, maybe I messed something up while doing that

[hasty prawn]

Add the -shaded one

I think the one you included doesn't have the Bungeecord stuff with it.

PacketPlayOutPlayerInfo probably

Or ClientboundPlayerInfoPacket if you're using moj maps

[left swift]

can I somehow move the jar file of my plugin built with maven to the plugins folder on my server so that I can debug? (localhost server)

[quaint mantle]

Create a symlink to your jar and put it in the plugins folder

[mental sapphire]

It also doesn't like having both

[hasty prawn]

Yeah don't have both

Just the shaded one

[mental sapphire]

That's the result from just the shaded one

[hasty prawn]

wat

[tender shard]

Does anyone know what kind of inventories a hopper can fill? I know it can fill furnaces and brewing stands, but what about e.g. enchantment table, loom, beacon, anvil, etc?

[left swift]

and how can i edit the name of the jar after building it? there is a name and it sticks a version that is different for me every time. I just wish I had a name

[quaint mantle]

Do you really change the version that often

[hasty prawn]

https://minecraft.fandom.com/wiki/Hopper#Container_interactions

[left swift]

its time

time is version, so i can see which build is latest

[tender shard]

perfect, thanks!

[left swift]

nvm, i have it

[hasty prawn]

Try restarting again, Eclipse is being dumb I think.

Because that JAR has all of those.

[loud haven]

Or switch to a different IDE that isn't Eclipse lol

[crimson verge]

intellij idea is so much better

[loud haven]

Agreed

[crimson verge]

i started on eclipse and didnt know what i was missing lol

[hasty prawn]

Same, IntelliJ was intimidating at first though.

Now I'm like

that makes no sense

/D is for directories

just remove the /D at the beginning

weird because the wiki says this is already a thing

[young knoll]

Where?

[tender shard]

oh I am stupid

it's listed here but it says it is NOT possible

I just saw it in the list and thought it should work then

[quaint mantle]

Can you make an array / list of blocks?

[tender shard]

sure, why not?

[quaint mantle]

Nvm I’m a dumbass Xd

I was getting an error and I forgot to define the var for the block array 🤦‍♂️

[loud haven]

lmao that got me too sometimes

[left swift]

that normal one works too

[tender shard]

--remapped is for when you need to access NMS

if you don'T use NMS, it doesn't matter whether you use --remapped or not

[left swift]

im using nms, and jar without --remapped, it works too

[tender shard]

yeah lol

but you have the obfuscated mappings

e.g. fields and methods will be called a, b(), c instead of playerConnection, getPosition(), etc

and you will have to change your code on every new MC release when not using --remapped

[left swift]

yes, when writing code i use remapped nms but when i add a plugin to the server does it matter?

[chrome beacon]

If you're not using the maven plugin to remap it won't work

https://i.imgur.com/WO7hOSh.png

this is my project structure

[tender shard]

does API depend on server, or other way around?

[charred echo]

other way around

server uses api

[tender shard]

did you install the API with mvn install?

[charred echo]

lmao

forgot.

thank you.

[tender shard]

np 🙂

[quaint mantle]

Or is there a dif way?

Would I just make a loop of spawning the particle over and over?

Nvm I can use a bukkit runtasktimer

[trim surge]

mans got some stairs

[charred echo]

i dont like hiding middle packages, idk why

[woeful crescent]

Can someone please explain data leaks to me?

Java is juggling with references, so why does it matter how big an object that you are storing is?

I thought that all objects exist somewhere else in memory, and all that's being kept when you make a variable is a reference to that object

[tender shard]

that's correct

but imagine you do not need an object anymore but keep a reference to it. that object will now forever take up memory

if you get rid of your reference, garbage collection will eventually free up the memory again

[quaint mantle]

when doing block.getRelative(BlockFace.UP).getType(); if it is an air block it should return Material.AIR right? or does it return null

[mental sapphire]

I think I figured out what the problem is, but not how to fix it
If I try to import org.anything the error is "org.anything cannot be resolved"
But if I try to import net.anything the error is "net cannot be resolved". I'm going to try intellij

[buoyant viper]

https://tryitands.ee

[vocal cloud]

BEAT ME TO IT. reeeeeeeee

[quaint mantle]

well i got an error when trying to check the material and it says it returns null but javadoc said it returns Material.AIR so didnt know xd

[topaz cape]

do anyone have anyidea why this doesnt work

?notworking

[undone axle]

"Does not working" is a useless statement. Please describe what exactly is not working, what you expect it to do, and what actually happens. If you get any console errors, also ?paste the entire stacktrace.

[trail bough]

Does not working, prefect engmislsh™️

[upper niche]

what is the difference between ADD_SCALAR and MULTIPLY_SCALAR_1 for attribute operations? they seem to do the exact same thing from my testing, which is just multiplying by the given value

[tender shard]

hit the maven reload button so that it downloads it

[topaz cape]

it just doesnt

im not dumb

lol

[trail bough]

adding adds... i think

[tender shard]

show the full maven output pls

[trail bough]

so if its 1 by default itll act the same

try a sword and its damage

[upper niche]

thats what i did

i used 2 as the value, set the modifier to the former, checked
+200% damage
changed the modifier to the latter, still +200% damage

[vocal cloud]

What even

Intellij forest edition

[topaz cape]

just add a background?

[tender shard]

that's not the full error

anyway, the plugin is in maven-central, it should be able to find it

try mvn clean package -U

[topaz cape]

well, this isn't a plugin.. so mvn clean install -U

[tender shard]

maven-javadoc-plugin

[topaz cape]

oh i found the issue

😮

[tender shard]

what was it?

[torn shuttle]

sonarlint fears my big brain

[quaint mantle]

Id there an event for button click or just playerInteractEvent

[sterile token]

JNI doesnt work with C# right?

Cuz c++ its similar to writing on assamble

[topaz cape]

maven doesnt recognise it in <plugins> you have to put it as a dependancy to dwnload

then remove it

😄

[tender shard]

that's normally not required lol

but the javadocs plugin goes into <reporting> and not into <build>

[topaz cape]

well it now works :DDDDDDDD ❤️

[tender shard]

maybe that was the mistake?

[quaint mantle]

Or is there a check or smth if they click button

[upper niche]

is there a way to get a Server instance from an ItemStack?

[unreal quartz]

Hey @ivory sleet you forgot to fix this

[trail bough]

how would i make something like essentialsx's variable home system? [like rgsmputilities.home.limit.15] since I imagine you don't want to code in hundreds of perm nodes manually. i'm still new to java so its probably a dumb question but it'd help

[young knoll]

They let you configure them via the config

So you basically add your own nodes as needed

[trail bough]

alright

but i just want it so they can have it be an integer instead of a set name pretty much

[young knoll]

Yeah I’d still go with a config

Rather than looping a bunch of numbers

[trail bough]

aight

[sullen marlin]

You could use getEffectivePermussions and loop their permissions

Though wouldn't surprise me to see permissions plugins break that, what with their Regex permissions and all

[trail bough]

so a while loop pretty much? i wanna just have it go from 1-25 so computation power isnt too much of an issue

[sullen marlin]

If it's just 1-25 I'd loop that

Since they prolly have more than 25 permissions

[trail bough]

well i dont think someones gonna really want to give more than 25 homes

so

shrug

[sullen marlin]

Real estate mogul

[trail bough]

i still need to figure out how to store homes but

[upper niche]

how do i read what blocks an itemstack is allowed to break or be placed on?

[vocal cloud]

Does anyone know if you can force close a book? I can't seem to find anything on it.

[young knoll]

I don’t think we actually have an API for that

[upper niche]

nms?

is it doable through that?

id know how to do it if nms itemstacks still had a getTag() method but they dont seem to anymore so i dunno

[young knoll]

Use remapped

[sterile token]

if you have a jni file you cannot get its source or yes? Im confused because with C# you cannot. And Java yes you can

Thanks

[worldly ingot]

RE: This. At least for our server we just have a pre-defined set of permissions in an array and check for those.

If you're making a public plugin, you could go with user-defined permissions as well, which is what I was considering doing in VeinMiner for maximum vein sizes

[trail bough]

hm

interesting

i'll probably go with what essentials does and have it be a list checkup. time to learn configs : D

it's probably gonna end up being named SimpleTeleports [tpa, home, sethome, maybe warp and setwarp]

[worldly ingot]

Just in your config,

max_home_permissions: [ 1, 5, 10, 25 ]

Then you can just iterate over that array

Check if they have the permission + "." + value

[trail bough]

thanks

[worldly ingot]

o/ Figured I'd offer an alternative

It's up to you

[trail bough]

i barely know while loops so this is pretty helpful

How should I save the homes then?

I'm going with files because I don't wanna hurt my brain with databases too right now, but should it just be pure coords or something like a miniocnfig

[young knoll]

Coords work fine

You can easily serialize a location to yml

[patent horizon]

    mavenCentral()
    maven {
        name = 'spigotmc-repo'
        url = 'https://hub.spigotmc.org/nexus/content/repositories/snapshots/'
    }
    maven {
        name = 'sonatype'
        url = 'https://oss.sonatype.org/content/groups/public/'
    }
}

dependencies {
    compileOnly 'org.spigotmc:spigot-api:1.18.1-R0.1-SNAPSHOT'
}```

[trail bough]

yeah but should it be something like
[uuid]
|
L_______ [Home1]
L_______ [Home2]

or

[uuid.yml]

[young knoll]

I would do 1 file per user

[patent horizon]

yeah you dont want to deal with multiple files

pain

[trail bough]

so just .yml? ok

[patent horizon]

yeah

[trail bough]

i'd do something like BukkitObjectInputStream in = new BukkitObjectInputStream(new FileInputStream(filePath)); then i guess

[young knoll]

Why, spigot has a yaml api

[trail bough]

oh it does?

[young knoll]

YamlConfiguration.loadConfiguration

[trail bough]

send javadoc link if you could

[young knoll]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/configuration/file/YamlConfiguration.html

[trail bough]

ty

[patent horizon]

    public String grabDataAsString(String dir, String file, String key) {
        YamlConfiguration yC = YamlConfiguration.loadConfiguration(new File("directory path"));
        return (yC.get(key) != null ? yC.get(key) : "None");
    }```

heres a method i use for it

[trail bough]

whats the 3rd line, eli5 please

[patent horizon]

basically just returns the value in the config from the given key

[trail bough]

ah ok

[patent horizon]

and if the value is null, it returns "None"

[trail bough]

oh smart

[patent horizon]

pretty sure it's called like the ellis operator or smth

[trail bough]

how do i write to it then?

[young knoll]

Elvis operator

[patent horizon]

ah

[patent horizon]

can please help

[trail bough]

sorry me no know :C

[sterile token]

Probably the 1.18 jar its not in that repository

[sterile token]

If you want i can send you my FileHandler based on YamlConfiguration

I have notice something that i never seen before

[trail bough]

sure why not

[sterile token]

Do you want the .class or the paste link?

[sterile token]

Here you have. If you have any dudes dm me/tag me

[trail bough]

What's the [dev.alex.net.utilities.Utilties] import?

[sterile token]

Its the main plugin class

[trail bough]

ah aight

[sterile token]

I explain you

If boolean parent:

1. True -> It will create a file with the content from your resource file (Like you should first create your file inside your jar)

2. False -> It will just create an empty file which you can add, remove, get, etc parameters

If you need more help Tag me or dm me

[quaint mantle]

whenever i spawn a particle for example campfire smoke it goes flying at like 400 mph one direction, how can i make it spawn a particle like smoke and stay in. the same place and just fade away like it should

[trail bough]

i think i'll use wally's version for locations

[quaint mantle]

if anyone respondes ping me

[eternal oxide]

Either your location has a vector or you are using the wrong spawn method and are adding a velocity

[patent horizon]

can someone give me the link to the docs that tell you what gradle/maven build stuff to enter for the spigot api?

all the sudden my old api links arent working now in my gradle.build

[jade perch]

https://www.spigotmc.org/wiki/spigot-gradle/#build-gradle

[torn shuttle]

I feel like I losing my mind with pitch and yaw coords

when I do getDirection it looks like they are flipped

as in yaw becomes pitch and pitch becomes yaw

[ancient plank]

😔

[torn shuttle]

which is which

on facing is the first coordinate yaw and the second pitch?

[eternal oxide]

Yaw and Pitch are rotations. getDirection returns a Vector.

[torn shuttle]

yeah, a vector pointing towards the direction of the pitch and yaw

[eternal oxide]

Yes

How are you seeing them reversed?

[torn shuttle]

if I set the pitch to 0 and yaw to 66 and teleport to that location I end up looking at the floor

but if I do math on the direction vector it shifts the y value but not the x or z values

sorry

if I do math on the direction it shifts x or z but not y

and if I invert it I shift y on the vector and teleport with a different horizontal viewing coord

[eternal oxide]

depends on the math I guess. Unless you are applying a rotation.

[broken hare]

I am trying to use RecipeChoice.MaterialChoice with 1.17.1 API, but my IDE and gradle compiler says that it can't find that symbol.

[torn shuttle]

here's the perfect example:
[EliteMobs] Developer message: Location: Location{world=CraftWorld{name=em_primis},x=1407.0,y=20.0,z=362.0,pitch=0.0,yaw=66.0} direction: -0.9135454576426009,-0.0,0.4067366430758002

yaw is 66

pitch is 0

on the direction, y is 0

that doesn't make sense

yaw should be the value setting the vertical value

actually looking at the API

        double rotX = this.getYaw();
        double rotY = this.getPitch();

can someone do a sanity check for me, I am pretty sure the api got it backwards

[broken hare]

Maybe this is the problem:

This class is not legal for implementation by plugins!

[buoyant viper]

yaw in minecraft is your horizontal (left/right) facing

pitch is your vertical (up/down)

actually i think thats how rotations work in general

[torn shuttle]

I think I found the issue

it's got to do with the direction

[dusk flicker]

yep

[torn shuttle]

I suspect updating a location's pitch / yaw doesn't modify its direction? so it shifts freely and in somewhat unpredictable ways

[dusk flicker]

ive had to deal with pitch and yaw way too much recently

just not in mc sadly lmao

[torn shuttle]

ok there is no way this is correct

it wasn't the direction

Hey everyone, does anyone know how to get the name of a block? For example: if I rename a button in an anvil, and then press the button, how do I know the name? I have tried .getMetadata and .getBlockData but can't seem to find anything. Thanks!

[hollow bluff]

Doesn't the name go back to default when placed?

[dusk flicker]

A block or an item?

As far as I know like SayWhatHappened said, when placed t he name resets iirc

[ancient plank]

yes

[dusk flicker]

Would recommend using PDCs if you need persistance

Serious Spigot and Bungeecord programming/development help

Ahh

So what i can do?

#help-server would be better

[sterile token]

Allright

[sullen marlin]

Sir this is a spigot’s

[sterile token]

Its not the same owner?

[crimson verge]

no lmao

forge is entirely separate

[sterile token]

Oh allright

I didnt know

[hardy swan]

even if it is the same owner....

[thick drum]

if (nameData.has(new NamespacedKey(HTTPPost.getPlugin(), key:"message"), PersistentDataType.STRING)) {
  p.sendMessage(ChatColor.GRAY + "There is already a command stored in this item!");
  p.sendMessage(ChatColor.GRAY + "Message: " + ChatColor.GREEN + nameData.get(new NamespacedKey(HTTPPost.getPlugin(), key:"message"), PersistentDataType.STRING));
                        
} else {
  nameData.set(new NamespacedKey(HTTPPost.getPlugin(), key:"message"), PersistentDataType.STRING, message,toString());
  item.setItemMeta(meta);
  p.sendMessage(ChatColor.GREEN + "Message Stored!");```

Just followed a tutorial on persistent data storage, does anyone know why eclipse throws "The method has(NamespacedKey, PersistentDataType<T,Z>) in the type PersistentDataContainer is not applicable for the arguments (NamespacedKey, PersistentDataType<String,String>)" on ```nameData.has``` ?

[young knoll]

Because you have key:”message”

And also message,toString

[thick drum]

Sorry if it's a dumb question, but what is wrong with key:"message"?

[young knoll]

Java doesn’t let you pass arguments by name

[thick drum]

Oh okay I think I get it, thanks!

[lavish hemlock]

That's why you should download an IDE :)

Wait sorry you did

That's why you should understand the language :)

Here are some links to get you started on learning Java:

• https://www.codecademy.com/learn/learn-java
• https://www.sololearn.com/learning/1068
• https://www.learnjavaonline.org/
• https://programmingbydoing.com/
• https://docs.oracle.com/javase/tutorial/java/index.html

The last one is the only official one, however some of those concepts assume that you already know a bit about programming.

[young knoll]

Afaik you can’t

But you can remove them from the list in the PlayerCommandSendEvent(?)

Then they won’t show up when the player tries to tab complete them

I think they can still use them tho? Idk

Impossible to intercept the tab completion before they add an argument

It will

But that isn’t intercepting the tab completion, it’s just removing it from them entirely

[opal sluice]

Hi, would this be a good approach to make a list add out of bound?

The goal here, is to be able to have for example, a list and then be able to add at any index even if the list isn't that long yet

    public static <T> List<T> insertToIndex(List<T> list, T toAdd, int indexToInsert)
    {
        if(indexToInsert >= list.size())
        {
            int loopAmount = indexToInsert - (list.size() - 1);
            for(int i = 0; i < loopAmount; i++)
            {
                list.add(null);
            }
        }
        list.set(indexToInsert, toAdd);
        return list;
    }

[young knoll]

No

Like I said, remove the commands from the list

[lavish hemlock]

ArrayList has an ensureCapacity method.

[opal sluice]

Oh, so I could directly do an ensureCapacity and then set the actual index right ?

[lavish hemlock]

Yeah basically.

[opal sluice]

Ok thanks ^^

[young knoll]

No

It fires when the commands are sent to the player

Which is usually when they join

[quasi patrol]

Does the getblock from the block break event get the block broken on the server side, or the client side? If it is the server side, how would I get the block broken on the client side?

[unreal quartz]

Sounds like a design issue tbh

[unreal quartz]

Server side, of course

[quasi patrol]

How can I get the block broken on the client side?

[opal sluice]

I would like to use it like a preset array but with the possibility to dynamically change the size of that array

[unreal quartz]

…?

[young knoll]

If you have changed the block on the client side it will change back as soon as they click it anyway

[quaint mantle]

Hi I was making a custom mob plugin and I tried to add a wither every 30 seconds but it won't let me do this java WorldServer world = ((CraftWorld) loc.getWorld()).getHandle(); world.addEntity(EntityWither.class); I have no idea why but can someone help me?

[quasi patrol]

Not if you cancel the interaction?

[young knoll]

Then you aren’t breaking the block

[quasi patrol]

Cancelling PlayerInteractEvent also cancels breaking client side blocks?

[sullen marlin]

you do not need nms for this

[quaint mantle]

I know but I was making a custom entity

wait I dont need nms to do the like spawn entity thing?

should I just do it the regular way?

with spigot?

[golden turret]

maybe he is cancelling that

if he is storing the fake block

then he can get the fake block

[young knoll]

True

It’s up to you to keep track of client side blocks

[golden turret]

if it is custom

then yes, nms

if not

use the api

[sullen marlin]

you cant map a void

you want forEach

or ya know, a for loop

[lavish hemlock]

You can still forEach an Iterable

No need for the Stream middleman

[thick drum]

How do I go about storing a string in a placed lever? Or within a lever item, which is callable when the lever is placed?

[young knoll]

For the item you can use pdc

For the block you can use https://www.spigotmc.org/threads/custom-block-data-persistentdatacontainer-for-blocks.512422/

[thick drum]

Alrighty I'll have a go, thanks!

[sullen marlin]

What brand server are you running

[trail bough]

Try fixing spigot on spigot first

to make sure it's a paper issue

[young knoll]

You can make a custom jar

Otherwise no, not without NMS/packets

[buoyant viper]

best part is his forEach is map

[hardy swan]

Guys im new to particles, why do particles burst out in random directions whenever I spawn them?

Is there a way for them to not move

[young knoll]

For most of them you set the extra int value to 0

As it controls the speed

[hardy swan]

Oh so Integer will govern the speed

[young knoll]

Generally yes

Particles are weird and inconsistent

[hardy swan]

Ah ok thanks!

[honest sentinel]

How may I use arraylist in an interface? I need it for CraftLivingEntity for different versions?

dk if its even a thing

I'm trying to get what's inside of public static ArrayList<CraftLivingEntity> Zombies = new ArrayList(); but I can't do it since I'm doing the whole version thing and I can't find a way to use it in multiple versions since I cant put CraftLivingEntity inside of the Arraylist in the interface

[alpine urchin]

what is your goal

but why not a list of LivingEntity

thats cross version

CraftLivingEntity implements LivingEntity

[honest sentinel]

Zombies.add((CraftLivingEntity) location);

I can't do that, that's the issue

actually nvm, I don't think I need it afterall

[alpine urchin]

need what

[honest sentinel]

The arraylist, I don't think I actually need it

[alpine urchin]

btw why don’t you follow java naming conventions

why did you name the list like that

[honest sentinel]

I just did i guess, ima fix it tho

[quaint mantle]

Did this fix it? I had the exact same issue and asked the exact same legit word for word question earlier xd

[hardy swan]

No it doesnt

Im thinking it is offset instead

Offset seems to be a value for a target location

Not spawn location as I thought it would be

[quaint mantle]

Ohh weird

[hardy swan]

Im testing it

[quaint mantle]

I set offset to 0,0,0 so that might be it

Just remove offset and lmk if it works

[hardy swan]

And there is a forth value

Which i assume is speed

[quaint mantle]

Extra

Ye

[hardy swan]

Set that to 0

[quaint mantle]

This is what someone said the issue was to be but

[hardy swan]

This is the correct way

Just tested

I assume particles are assign random vectors when you spawn it

[hardy swan]

This is wrong

[quaint mantle]

So what do I change? Lol

Set extra to 0?

[hardy swan]

Yep

[quaint mantle]

Kk ty

[alpine urchin]

Well you know the conventions?

in that case since its static make it ZOMBIES

otherwise if not static make it zombies

[young knoll]

Isn’t that only static final

[quaint mantle]

only static final and if immutable

[quaint berry]

Quick question...
Can I detect a model id for an item through code?
If not can I check through protocol lib?

[young knoll]

Like the custom model data value?

[spiral light]

i think he wants those methods from ItemStack#getItemMeta()

[jolly acorn]

  panel-1:
    perm: default
    rows: 5
    title: '&8Generated panel-1'
    empty: BLACK_STAINED_GLASS_PANE
    item:
      '20':
        material: DIAMOND
        stack: 1
        name: '&d&lBUY VIP+ ROLE'
        commands:
          - 'paywall = 300000'
          - 'add-data= vip+ bought'
          - 'msg= Thank You For Buying Vip+!'
          - 'console= lp user %cp-player-name% parent set vip+'
      '24':
        material: GOLD_INGOT
        stack: 1
        name: '&6&lBUY VIP ROLE'
        commands:
          - 'paywall = 100000'
          - 'add-data = vip bought'
          - 'msg= Thank You For Buying Vip!'
          - 'console= lp user %cp-player-name% parent set vip'```

i wanna add a notif like where if they buy it they cant buy it again how do i fix this?

[spiral light]

seems like you use some api to use a config file to generate an inventory
but its not the spigot api ^^

[jolly acorn]

i use commandspanel plugin

i dont know what to add on the buttom to make it like say them "Youve Already Bought This!" like that

[jolly acorn]

since i cant understand a thing on the videp the developer sent me

since iam from the philppines and i cant understand the code in the video

[spiral light]

yeah but how should we know how a plugin works ^^

is the video java and in english ?

[jolly acorn]

yes

heres the wiki

[quaint berry]

So can I check if someone is eating a golden apple with a certain model tag then run another code if that is happening?

[jolly acorn]

  panel-1:
    perm: default
    rows: 5
    title: '&8Generated panel-1'
    empty: BLACK_STAINED_GLASS_PANE
    item:
      '20':
        material: DIAMOND
        stack: 1
        name: '&d&lBUY VIP+ ROLE'
        commands:
          - 'paywall = 300000'
          - 'add-data= vip+ bought'
          - 'msg= Thank You For Buying Vip+!'
          - 'console= lp user %cp-player-name% parent set vip+'
      '24':
        material: GOLD_INGOT
        stack: 1
        name: '&6&lBUY VIP ROLE'
        commands:

          - 'msg= Thank You For Buying Vip!'
          - 'console= lp user %cp-player-name% parent set vip'```

and heres the code i have rn

[quaint mantle]

Yes? Use the interact event?

[jolly acorn]

just add the thing that notifs when u already bought it it says when they tryna buy it again it says "You Already Have This Role" thingy when they tryna buy it again

[quaint berry]

So I can check for a certain model tag and it won't screw up?

[quaint mantle]

Why would it

[spiral light]

you want me to add this ?

[jolly acorn]

yes

i also dont want them to buy it when they already have bought this role

[spiral light]

i am (and i think almost everyone else here) not here to code stuff for you ^^
if you use an other plugin to do stuff and dont know how to use it - we maybe dont know how it works too ?
you will need to understand their plugin and if you have a problem you should contact the plugin-dev

hmmm wondering if this is bannable here

everything ok with you ?

how do i check if the helmet slot is null but other slots are?

[lost matrix]

Slot IDs:
http://redditpublic.com/images/b/b2/Items_slot_number.png

[coarse shadow]

to check all slots except helmet slot, do i need to add those slots to an arraylist?

or do i need to check them one by one

[low temple]

I think there’s a .getEquipment() or .getHelmetSlot() method within a PlayerInventory Object

[coarse shadow]

there is getHelmet method

[lost matrix]

There are 5 approaches:

    EntityEquipment equipment = player.getEquipment();
    ItemStack helmet = equipment.getHelmet();
    ItemStack chestPlate = equipment.getChestplate();
    ItemStack leggings = equipment.getLeggings();
    ItemStack boots = equipment.getBoots();

    PlayerInventory inventory = player.getInventory();
    ItemStack[] armor = inventory.getArmorContents();
    ItemStack helmet = armor[3];
    ItemStack chestPlate = armor[2];
    ItemStack leggings = armor[1];
    ItemStack boots = armor[0];

    PlayerInventory inventory = player.getInventory();
    ItemStack helmet = inventory.getHelmet();
    ItemStack chestPlate = inventory.getChestplate();
    ItemStack leggings = inventory.getLeggings();
    ItemStack boots = inventory.getBoots();

    PlayerInventory inventory = player.getInventory();
    ItemStack helmet = inventory.getItem(EquipmentSlot.HEAD);
    ItemStack chestPlate = inventory.getItem(EquipmentSlot.CHEST);
    ItemStack leggings = inventory.getItem(EquipmentSlot.LEGS);
    ItemStack boots = inventory.getItem(EquipmentSlot.FEET);

    PlayerInventory inventory = player.getInventory();
    ItemStack helmet = inventory.getItem(103);
    ItemStack chestPlate = inventory.getItem(102);
    ItemStack leggings = inventory.getItem(101);
    ItemStack boots = inventory.getItem(100);

[coarse shadow]

aight so lets say i've one of these approaches

if the slot is empty and i call isEmpty method, will it call true?

[low temple]

depends what you do

if youre checking the helmet

you can use .getHelmet() and check if its null

itll either be null or Material.AIR

[coarse shadow]

i'm checking if the helmet is not null and other slots are

[low temple]

if youre checking the type

[lost matrix]

in those examples helmet, chestPlate, leggings and boots can all be null

[low temple]

@lost matrix are empty slots considered null or air?

[hardy swan]

Air

Equipment is air

[lost matrix]

If its in the players hand then its air. Otherwise its null.

[coarse shadow]

yea thats where my head is confused

[hardy swan]

Inventory is null

[low temple]

does the .getMaterial() method on a null itemstack return Material.AIR?

[hardy swan]

Null dont have methods

[low temple]

oh right

[coarse shadow]

so i should say helmet != Material.AIR if i want helmet not to be null right?

[lost matrix]

If you call anything on null then it throws an NPE

[low temple]

Material is for the type

[lost matrix]

Im almost certain that armor is null if not present

[coarse shadow]

oh ok

[low temple]

so you would do "inventory.getHelmet() != null"

[coarse shadow]

thanks

also another question

[hardy swan]

The last i checked equipment always return nonnull

Maybe im tripping

bruh they didnt pay the paywall but still got vip+ and vip 😐

[coarse shadow]

can we get value names from persistent data containers

not key names, values

[jolly acorn]

how do i fix this

[low temple]

Yeah

[coarse shadow]

how

all i've seen was getting key names and not values

[low temple]

so you need to get the persistent data container value

so you would do container.get(new NamespacedKey(<Plugin variable>, <String key>), PersistentDataType.<Data type>);

i need help! they didnt pay the "paywall" but still got the vip role !!! how do i fix this!?

[coarse shadow]

wait i asked wrong

we can get vales

[lost matrix]

This channel is for development related questions

[low temple]

Oh you want to get all the keys? or search the keys by value?

[coarse shadow]

can we check if a key has a value that we ask for

[jolly acorn]

thanks for letting me know

[lost matrix]

#help-server

[low temple]

Like check if the key has a value?

[jolly acorn]

thanks 😄

[low temple]

or check the datatype of the key?

[coarse shadow]

no

lets say i want a key that has "blabla" value but i didnt create it. i want to check if the item has any key with that value

[low temple]

Hmm

you might be able to do the .getKeys() method, loop through those and see if it matches ur value

theres a very low chance youll get interfearing keys from other plugins

you can make the key to basically whatever you want

[coarse shadow]

got it thx

[low temple]

@coarse shadow btw when you use the .getKeys() and use the .forEach() method, the variable will be the namespacekey itself

so youll have to do key.getKey()

[lost matrix]

You should never use PDCs like that

[low temple]

PersistentDataContainer container = player.getPersistentDataContainer();
container.getKeys().forEach(key ->{
    if (key.getKey().equals("your_key")) {
        // Do something
    }
});

as smile said, this is often unneeded and you really shouldnt be making PDC without having a reasonably unique key

[lost matrix]

This is how you should use PDCs.

  private final NamespacedKey tagKey = Objects.requireNonNull(NamespacedKey.fromString("some-namespace:some-key"));

  // Sets or overwrites a tag
  public void tagItem(ItemStack itemStack, String tag) {
    ItemMeta meta = itemStack.getItemMeta();
    PersistentDataContainer container = meta.getPersistentDataContainer();
    container.set(tagKey, PersistentDataType.STRING, tag);
    itemStack.setItemMeta(meta);
  }

  public boolean isTagged(ItemStack itemStack) {
    ItemMeta meta = itemStack.getItemMeta();
    return meta.getPersistentDataContainer().has(tagKey, PersistentDataType.STRING);
  }

  // returns a String or null if not present
  public String getTag(ItemStack itemStack) {
    ItemMeta meta = itemStack.getItemMeta();
    PersistentDataContainer container = meta.getPersistentDataContainer();
    return container.get(tagKey, PersistentDataType.STRING);
  }

[hardy swan]

Bruh how to declare a number to be a float

Or must cast

[lost matrix]

float x = 1;

or float y = 1.0F;

[hardy swan]

Ok nvm

[spiral light]

or float f = (float) 20D;

[lost matrix]

1.0 is a double 1.0F is a float

[hardy swan]

I was thinking why F isnt working, the method doesnt accept float :)

[lost matrix]

[buoyant viper]

too bad it cant be D20

would be 20

Some additions to that:

1. Never make data structures public.
2. Dont use Player as a key unless you properly clean it up

[trail dragon]

How can I access the hashmap from other classes then?

[lost matrix]

Via mutators and accessors.
public void setPoints(Player player, int score)
public void addPoints(Player player, int points)
public void getPoints(Player player)
and so on.

[trail dragon]

ahh okay i see

thank you!!

[lost matrix]

Btw you are somewhere creating an instance of MCBACore
In spigot you are not allowed to instanciate JavaPlugin classes.
You are probably doing this in your ResetPoints or CheckPoints constructor

[opal juniper]

7smile7 pink again 👀

[trail dragon]

MCBACore core = new MCBACore(); yeah that is how i was accessing the hashmap

and then core.score.get(target)

[lost matrix]

1. Every new instance of MCBACore has its own HashMap. So this wouldnt work in the first place.
2. You are not allowed to create instances of JavaPlugin classes in spigot.

[trail dragon]

ohh right

[lost matrix]

So what you want to do is add a parameter to your ResetPoints and CheckPoints constructors like this

private final MCBACore plugin;

public CheckPoints(MCBACore plugin) {
  this.plugin = plugin;
}

And then call them in your onEnable with the current instance you are in:

        getCommand("points").setExecutor(new CheckPoints(this));

There is only one single instance of MCBACore.
And you need to makes sure that other classes become this one instance provided.

[trail dragon]

I'm a bit confused. Heres my code https://github.com/GoldenEdit/MCBACore

[lost matrix]

Example for CheckPoints.class:

public class CheckPoints implements CommandExecutor {

    MCBACore core = new MCBACore();

    @Override
    public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
    ...

To

public class CheckPoints implements CommandExecutor {

    private final MCBACore core;
    
    // This is your contructor
    public CheckPoints(MCBACore core) {
      this.core = core;
    }

    @Override
    public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
    ...

Dont create a new instance of MCBACore.
Let the the caller of new CheckPoints(MCBACore) pass an instance of MCBACore

But those are Java basics. And i mean basics you should know after at most 2 Weeks of Java.

Maybe 3

unless there's some mojang request that allows you to get it from an undashed uuid, I feel like ive seen something like that before

You can’t even define a variable with name 1

[hardy swan]

That's what i am trying to illustrate to @vague swallow

[lost matrix]

x = y
Then x2 = xy
Subtract the same thing from both sides:
x2 – y2 = xy – y2
Dividing by (x-y), obtain
x + y = y
Since x = y, we see that
2 y = y
Thus 2 = 1, since we started with y nonzero
Subtracting 1 from both sides:
1 = 0

Dividing by 0
