[inner mulch]

im getting this error, i think i didnt close my connections properly, but even after restarting the db and my pc it still says this.

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

[smoky anchor]

My guess would be me.galtap.customblockdata

[upper hazel]

hm

[smoky anchor]

but again, not the problem
what jar are you using ?

it should generate like 3

[upper hazel]

i use 1.20.1

[smoky anchor]

that doesn't tell me anything

[upper hazel]

bukkit api

[smoky anchor]

I'm asking about the jar, not version

[upper hazel]

oh

[smoky anchor]

your plugin jar

[upper hazel]

java version?

[upper hazel]

i try but this not work

not found class

[peak depot]

how can I have one main Team and of that I want to create copys of the team and set custom suffix for each player thats my code for the teams in general: https://paste.md-5.net/gofiqerogu.cpp

[smoky anchor]

ye, that was not your issue
I just pointed that out 'cause it was incorrect anyways

when you run the maven build or whatever it creates these jars
which one do you use

[upper hazel]

i dont know what the path need

what the

i not find this

steves-fanny-liblary??

[smoky anchor]

that is my plugins id
yours would be different

[upper hazel]

this?

[smoky anchor]

How did you get to Task Manager

[upper hazel]

write task Manager in search engine

[opal carbon]

they are asking why tf

[grim hound]

he did not mean that literally

[slender elbow]

man what is going on lmao

[deft thistle]

Press control shift and esc at same time

[river oracle]

Spigot

[opal carbon]

steve wanta to know why tf ur in task manager

[smoky anchor]

Guys, I do really bad with language barriers

[upper hazel]

what next

[echo basalt]

@ivory sleet is this accurate

[opal carbon]

not how to get there

[opal carbon]

i got it they just goofy

[smoky anchor]

What plugin jar do you put into your plugins folder ?
You might be using the wrong one.
@upper hazel

[upper hazel]

i was do this but the same window

BarrelMarket

[smoky anchor]

What is the full file name

[upper hazel]

me.galtap.barrelmarket.BarrelMarket

or not this

[smoky anchor]

That is not the name of the file

[upper hazel]

just BarrelMarket.jar

[slender elbow]

thank you conclube

[icy beacon]

Gg

Now Illusion also deserves a role of Discord Helper

[ivory sleet]

[icy beacon]

When to expect that?

[echo basalt]

I'd probably be biased and remove magma's messages from my search index lmao

[icy beacon]

Lmao

Long overdue

[ivory sleet]

Illusion, just… can variables be synchronized!?

[echo basalt]

p sure static variables can

[icy beacon]

Svelte reference

[echo basalt]

actually no

static methods can

variables can't

[icy beacon]

Still svelte reference

[echo basalt]

but there's volatile which ensures that cpu caches n stuff are synched between threads

innit

[slender elbow]

except for doubles and longs, field assignment is atomic

[icy beacon]

Why doubles and longs though?

What about other primitives

[slender elbow]

because it may happen in two 32-bit steps

[icy beacon]

Ahh

[upper hazel]

oh wait i now see i need shodow plugin

[slender elbow]

it's not guaranteed it'll be atomic, but it's also not guaranteed it won't be

but "jvm implementations are highly encouraged to make it atomic"

[unreal maple]

GSON - Expected BEGIN_OBJECT but was STRING

[slender elbow]

but you can however use a Double/Long field and its assignment will be atomic :pepw:

at the expense of boxing ofc

or just stick an atomicfieldupdater/varhandle in there and it'll do the job pretty well done

[echo basalt]

I have more to do with my life than learn about jvm internals thank you very much

[dry hazel]

very true

[glad prawn]

volatile 😡😡

[slender elbow]

you see, i used to think the same

but then i got the itch

i get this itch, it's awful, i need to test all the time, keep testing

[echo basalt]

maybe you just need friends

[slender elbow]

i see you haven't played portal 2 D:

[inner mulch]

im getting this error, i think i didnt close my connections properly, but even after restarting the db and my pc, it still says this.

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

[echo basalt]

I have

like 5 years ago

[eternal night]

no one wants to be friends with emily

[young knoll]

oof

[eternal night]

oh shit

[echo basalt]

bro has a socket leak

[eternal night]

congrats collin

[slender elbow]

you're lucky i can't send images in here

[inner mulch]

yes pls help me

[echo basalt]

you're too scared to verify

[slender elbow]

i hate my nickname on spigotmc

[echo basalt]

pay 10 dolla

[slender elbow]

can't

[eternal night]

[echo basalt]

broke

[slender elbow]

gov restrictions for international payments yada yada

[inner mulch]

@echo basalt how do i fix a socket leak

[young knoll]

What if you have MD fly to you and pay him directly

[icy beacon]

Where are you from

[dry hazel]

being unverified is cooler anyways

[young knoll]

You guys can change names still

[slender elbow]

i was about to say something very racist

[young knoll]

Can't ya

[icy beacon]

Please do

[slender elbow]

lmao no

[smoky anchor]

https://tenor.com/view/good-morning-do-it-gif-24435329

👀

[icy beacon]

This server is NOT family friendly

[echo basalt]

https://tenor.com/view/monkey-monke-neuron-activation-neuron-activation-gif-20850506

[icy beacon]

Fuck fuck

[umbral ridge]

How would I synchronize real life time with ingame world time?

[young knoll]

Not too hard, just gotta do some math to convert the time

[umbral ridge]

😢

[echo basalt]

first you need the player's timezone

then you just do uhh

[young knoll]

Well

[echo basalt]

rule of third

basically just make a ratio

[eternal oxide]

and resync now and then due to lag

[young knoll]

I was asuming you wanted to do it to a single timezone

[icy beacon]

Photography reference?

[echo basalt]

no

math

[icy beacon]

Photography reference.

[young knoll]

Do you want just one timezone or do you want it per player

[echo basalt]

here it translates to "rule of 3 simple"

[inner mulch]

im getting this error, i think i didnt close my connections properly, but even after restarting the db and my pc, it still says this.

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

pls help me

[echo basalt]

it's like

[umbral ridge]

I cant use the players timezone. Has to be the servers timezone and time since each player can join from different areas of the world

[echo basalt]

x - y
z - ?

? = z * y / x

[young knoll]

Alright

[orchid gazelle]

Then you gotta get the local time of your machine

[umbral ridge]

That's it?

what is z x and y

[orchid gazelle]

If you give me like 40 mins I can give you the whole code for it lmao, I wrote it once

[echo basalt]

literally any number

[young knoll]

You can get local time various ways

[echo basalt]

it's like

2 ratios

[umbral ridge]

No its ok Ill write it myself

[orchid gazelle]

Ok

[umbral ridge]

I like a challenge xD

[echo basalt]

let's say you have a 2:1 ratio

[young knoll]

LocalTime.now() seems good

:p

[echo basalt]

you can do like

2 - 1
100 - ?

? = 100 * 1 / 2 = 50

[young knoll]

One thing that might catch you, minecraft time is from 0 to 24000

[echo basalt]

and this works for anything

[young knoll]

But 0 isn't midnight, it's sunrise

Midnight is 18000

[umbral ridge]

So.. I use milliseconds as a time unit I guess

or seconds

do some conversion

[icy beacon]

Seconds should be the closest

[echo basalt]

you can use seconds and do the rule of 3 to convert it

add an 18000 offset

and mod by 24000

[orchid gazelle]

Yes exactly

[umbral ridge]

Alright thansk

[young knoll]

LocalTime has getSecond :p

[slender elbow]

LocalTime 🙏

[icy beacon]

Waiting for when Java API adds LocalTime.toMinecraftTime()

[echo basalt]

[umbral ridge]

LocalEmily

[echo basalt]

lmao I have a MinecraftTime class at work

for scripting stuff

[icy beacon]

share

[upper hazel]

this my path - me.galtap.barrelmarket.CustomBlockData - but server not can find java.lang.NoClassDefFoundError: com/jeff_media/customblockdata/CustomBlockData - naven -> https://paste.md-5.net/atipavuwos.xml

[echo basalt]

lets me script stuff like wait 30 ticks

[upper hazel]

oh wait

[echo basalt]

something something

relocation

[young knoll]

Does it just schedule a task :p

[echo basalt]

maybe

I just have a Time class for my other projects with a basic parser

lets me do stuff like

TimeParser.parse("2 minutes 5 seconds").toTicks()

[orchid gazelle]

My life is an Illusion

[young knoll]

I should get something like that for my api

Maybe I should dedicate a day to working on my api

[icy beacon]

Send the TimeParser class here right away

I currently have no use for it but it looks sick so I want it

[inner mulch]

im getting this error, i think i didnt close my connections properly, but even after restarting the db and my pc, it still says this.

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

[echo basalt]

it's rly basic

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

[young knoll]

Nice

[echo basalt]

yes I could implement checks so that idiots don't put 1 second 1 second and end up with 2 seconds

but do I care

[young knoll]

I mean

Technically valid even if it's dumb

[icy beacon]

For some reason I thought it was like a 400 line class with a shit ton of parsing utilities xD

[spare hazel]

what item can i use for discord that is not a player head

[icy beacon]

Purple concrete ig

Why not a player head though

[young knoll]

Yeah the discord icon head looks pretty good

[spare hazel]

not compatible with my custom items api

[icy beacon]

Then your api is incomplete

[spare hazel]

alr imma make a PlayerHeadCustomItem

[icy beacon]

Can't that be abstracted???

What is even

Ok I'm not questioning it

[spare hazel]

yes

[icy beacon]

I'll keeop coding

[spare hazel]

public abstract class CustomItem {}
public abstract class PlayerHeadCustomItem extend CustomItem {}

[icy beacon]

I don't see why you would need to define specific logic for player heads

When it's an item like all others

[spare hazel]

would that work

[icy beacon]

I have no idea what your current system is and I don't have enough patience to study the code

So I can't say yes or no

But I can say that this approach feels scuffed

Because PlayerHeadCustomItem implies that it has different logic from other custom items

Which is simply not true

It has its own meta yes, that's not a problem though

Store it like any other meta

[spare hazel]

i want my project to be as structured and scalable as possible

[glad prawn]

which class would extend PlayerHeadCustomItem

[spare hazel]

WearablePlayerHeadCustomItem

[icy beacon]

So you are going to make a class for every item?

[spare hazel]

Every Item Type

[river oracle]

Seems like you need a util method not a class

[young knoll]

My custom item classes just wrap an itemstack

Then you can have interfaces to add for different stuff

[icy beacon]

oh my fucking god

please do not

do that

do not make a class

for every type

there is literally 0 reason to do so

[glad prawn]

imagine u have like 100 items

[icy beacon]

less code is better code

[glad prawn]

type

[young knoll]

You custom items shouldn't be bound to minecraft types

They should be bound to their different functions

[echo basalt]

I have my custom material class

that just wraps a custom namespacedkey class

and it all goes in a custom registry class

[spare hazel]

public ItemStack build(){
        ItemStack item = new ItemStack(material);
        ItemMeta meta = item.getItemMeta();;
        meta.setDisplayName(name);
        meta.getPersistentDataContainer().set(IranSkyLobby.getPlugin().getItemKey(), PersistentDataType.INTEGER, id);
        meta.setLore(Arrays.stream(lore).toList());
        item.setItemMeta(meta);
        return item;
    }```
its a pretty simple custom items api cuz its only for the lobby

[young knoll]

You could have a generic CustomItem
Then various interfaces like UsableItem, TickingItem, etc

[lost matrix]

Arrays.stream(lore).toList() ?

[echo basalt]

and my custom itemstack class with my custom meta class handles all the item stuff which is then adapted with a custom adapter class into a bukkit itemstack

smile lurking

[echo basalt]

who needs List.of

[young knoll]

I use my ItemBuilder class a ton

Tis nice

[spare hazel]

i used String[] cuz it was easier

[icy beacon]

In what world

[lost matrix]

How about Arrays.asList(lore)

[icy beacon]

is using arrays

easier than lists

[river oracle]

Just use an array list and define the size you want

[spare hazel]

lemme try

[river oracle]

It makes arraylist as fast as arrays

[young knoll]

Does it really matter much

We are talking about tiny lists

[spare hazel]

yeah that works

[river oracle]

No but that's really thr only valid justification for not using an arraylist here

[young knoll]

Fair

[icy beacon]

You'd be a good lawyer

[young knoll]

What is the default list size? 10?

[river oracle]

ArrayList is just a simple dynamic array

[young knoll]

Yeah but it has a default size

[river oracle]

I forge t

Not on pc so can't check

[river oracle]

I usually manually set it if I have a ballpark estimate

[young knoll]

Yeah it's 10

And then it grows by some amount if it gets full

Which I think depends on impl

[river oracle]

Iirc it's 1.5 or 1.25

[icy beacon]

Gg

[river oracle]

@lost matrix do you know?

[spare hazel]

how can i modify the username of the playerhead

[lost matrix]

Hm?

[river oracle]

Growth rate of array list

After it fills

[icy beacon]

I have no idea what this means

[young knoll]

It's 50% in java 8+

int newCapacity = oldCapacity + (oldCapacity >> 1);

[lost matrix]

Wait, oldCapacity is right shifted?

[spare hazel]

java makes no sense

[lost matrix]

Ah and added to itself

[spare hazel]

bump

[young knoll]

Not easily

[icy beacon]

Makes a lot of sense actually. Just not comprehensible for my eyes that do not do shifting ever

[young knoll]

You could do some custom display/interaction entity magic

Or a bunch of packet fuckery

[lost matrix]

Change the name of the PlayerProfile on that head

[young knoll]

Oh wait playerhead item

[spare hazel]

does it need NMS?

[young knoll]

Not the name above the player

[river oracle]

No

Bukkit has an api

[young knoll]

No, heads just have a displayName like any item

ItemMeta#setDisplayName

[spare hazel]

no the head that it displays

[young knoll]

wdym the name

Like the owning player?

[river oracle]

Set the skin base64 in the PlayerProfile

[young knoll]

^

[river oracle]

You should really be using a new player profile

[young knoll]

Or you can pass an offline player directly

[lost matrix]

Copilot... why u know my ingame name?

[young knoll]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/inventory/meta/SkullMeta.html for refrense

[river oracle]

💀

Copilot scaru

[lost matrix]

    URL skinUrl = ...;
    ItemStack head = ...;
    SkullMeta meta = (SkullMeta) head.getItemMeta();
    PlayerProfile profile = Bukkit.createPlayerProfile("Mr Bob");
    PlayerTextures textures = profile.getTextures();
    textures.setSkin(skinUrl);
    profile.setTextures(textures);
    meta.setOwnerProfile(profile);
    head.setItemMeta(meta);

[echo basalt]

why does it know my alts name

[river oracle]

You guys use copilot?

[echo basalt]

yes

[river oracle]

I quot using it a while back tbh

It made me brain dead

[echo basalt]

wacky ass take: copilot should only be used if you know what you're doing

https://tenor.com/view/speed-yes-plants-vs-zombies-trolling-gif-23575899

[spare hazel]

'setOwner(java.lang.String)' is deprecated
should i care? theres no way to create a new OfflinePlayer

[lost matrix]

I had it off for a while bc it kind of suggested a bunch of mumbo jumbo to me

[lost matrix]

Did you look at the code ive sent you?

[echo basalt]

oh yeah it turns to garbage if you invalidate your caches

[lost matrix]

#help-development message

[echo basalt]

and sometimes you gotta really insist

but it's still helpful

except when I want it to be helpful

[spare hazel]

oh i didnt notice that

[echo basalt]

it has days where it's great at making garbage but struggles to read a byte[] from a file

[young knoll]

Real important question

How do you order your classes

[echo basalt]

packages

[young knoll]

as in, public methods, private methods, getters/setters, static methods

[echo basalt]

well

stardards bruv

[spare hazel]

im on 1.16.5 and theres no createPlayerProfile

[young knoll]

Rip

No player profile api on 1.16, have fun with NMS

[echo basalt]

static fields
fields
constructor
most used / important methods up top
garbage / filler methods at bottom

[young knoll]

Yeah that's logical

[lost matrix]

// static fields
// static methods
// space
// class fields
// constructor
// methods

// public
// protected
// private

[echo basalt]

oh yeah I leave a line in between like every other line

[young knoll]

Interesting

Static methods at the top

[spare hazel]

is there a head database API that i can compile into my plugin?

[lost matrix]

I really like to separate static from the rest

But its more conventional to put them somewhere down

[young knoll]

mmm

[spare hazel]

nevermind imma just use blue concrete

[lost matrix]

Good think IJ has formatting rules for that 🙂

[young knoll]

fancy

[lost matrix]

The only thing im not sure about are the order of those two:

[worldly ingot]

init blocks above the constructors, always

static { }

{ }

Constructor() { }```

They're unnamed constructors

[lost matrix]

Hm? They get executed on class loading...

static init blocks *

If i see you write non-static init blocks then you get a slow headshake in disbelief from me

And the static ones are insanely dangerous bc they can create horrible classloader exceptions that are hard to debug

[slender elbow]

i mean sometimes you don't really have a choice, but they defo should be kept minimal

my favourite thing about init blocks is that you can have multiple of them lol

it's horrible

[lost matrix]

Oh yeah. That sounds nice 🙂

[sterile token]

What plugin You are using for that.styling You sent in the picture

Also welcome yo the stuff, really nice to see You un the stuff with Coll

[lost matrix]

None

[rotund ravine]

It’s great

[icy beacon]

Copilot is great for making mundane, routine tasks quick

[rotund ravine]

Ye

[icy beacon]

I don't really use it for coming up with code but holy hell it's saved me tens of hours just repeating code

[rotund ravine]

It does great at some tasks

[spare hazel]

how can i change project java version in IJ using maven

[meager wolf]

im trying to stop players from dropping an item from their inventory, they can move it but not drop it and this is what i made so far :

@EventHandler
    public static void onDropItem(PlayerDropItemEvent event){

        if(!hasCustomTag(event.getItemDrop().getItemStack())){return;}

        event.getPlayer().sendMessage("§cYou are not allowed to drop your §4§lRelic§r§c.");
        event.setCancelled(true);
        
    }

and it has a few problems:
1- if i open inventory and then click Q on items, they disappear but i get the "u are not allowed ..".
2- if i drag the item and right click outside of the inventory it gives me the item x2 (dup)

it only works well if i throw items from hotbar without opening the inventory

[rotund ravine]

Theres a few more eventd

Events*

Also what gamemode are you in

[meager wolf]

survival

[lost matrix]

https://www.baeldung.com/maven-java-version

[meager wolf]

i think

let me make sure

[robust helm]

InventoryClickEvent triggers when dropping from inventory

[meager wolf]

tysm

[tough mica]

Hello, i want to code a gun plugin. Now I want to do this animation when player shoot like in this video? how is this possible? I mean that the gun in the itemHand gets down and then up:
https://streamable.com/c596in

[rough drift]

Does the TabCompleteEvent contain the command the player is tab completing?

[rotund ravine]

Think it’s the buffer

[smoky anchor]

My guess would be to change some random NBT (PDC) of the item.
I think that causes this "pickup" animation.

[tough mica]

okay, then i have to change my texturepack too?

[rotund ravine]

what

[tough mica]

?????

i just have to set a random nbt tag?

and then i will get this animation?

[rotund ravine]

That’s indeed what he suggested

[smoky anchor]

yep, just have some random boolean in
it should cause it

[glacial narwhal]

How can i spawn a platform in glass at world generation ?

[rotund ravine]

?blockpopulator

Oh wait just once

Look at world events or whatever is used for creating the worlds

[tough mica]

okay i will try it

IT WORKS!

thank you very much

[upper hazel]

when i try use lib i have expetion notClassFound https://www.spigotmc.org/threads/custom-block-data-persistentdatacontainer-for-blocks.512422/ i was think bc i was do mistake when try paste path in configuration but my path written correctly

[smoky anchor]

How do you build your jar ?

[upper hazel]

wdym

[wind veldt]

Depending on the IDE, you probably can just run the code lol

It's gonna compile, at least on IJ

[icy beacon]

For maven it's mvn clean package

For gradle i think you just run gradle build

But I'm not experienced with it so I might be wrong

[smoky anchor]

Eeeh not really
not if you use maven

[wind veldt]

I literally use maven in IJ and works fine

lmao

[smoky anchor]

yes, but you have to setup the run profile thingie

[icy beacon]

whaT

Just run the command

[wind veldt]

what

whats the setup thingie

[icy beacon]

You've built your plugin at least once

Why are you asking

[smoky anchor]

I am not asking

[upper hazel]

yes

[icy beacon]

Ohh my bad

[smoky anchor]

I am asking the guy how he builts the jar

[icy beacon]

I thought you were asking for help lmao

[rotund ravine]

Mostly fine

[icy beacon]

Why mostly?

[rotund ravine]

Well if ur shading

You would need to add some extra options for build to shade

[icy beacon]

Ah, gotcha

[rotund ravine]

Otherwise the task would be shadowJar

[upper hazel]

so i need shadow?

[wind veldt]

yo, what's the use of shading? Never used that jar out of the three of them

[rotund ravine]

Probably not super needed with the newer plugin lib loading

But it’s a way to include the libraries that you use within your jar

[wind veldt]

oh, alright

[eager smelt]

How is the Vault API used?

[peak depot]

https://github.com/MilkBowl/VaultAPI

wait wrong link

[smoky oak]

can i spawn a beacon beam as indicator or is that bound to the beacon block
nvmind its client side

[peak depot]

nvm the right link

[smoky oak]

is it smart to make runnables used in exactly 1 class as static inner classes?

actually why does IJ suggest making inner classes static anyway if my code instantiates em?

[hazy parrot]

probably because you are not using enclosing class members

in that case, it can be static

[smoky oak]

'enclosing class members'?

oh that

like the Outer.Inner thing

[hazy parrot]

fields from class that is not nested xd

[smoky oak]

i mean, static fields for dynamic stuff sounds like a good way to screw stuff up

[river oracle]

Generally you shouldn't ever really come across inner classes that are non static

[smoky oak]

wait

afaik only inner classes can be static classes in the first place

ah the edit

[river oracle]

A non inner static class would signal a tight coupling with some non static field from the parent class

Which imho is just an anti pattern

[smoky oak]

are you implying that inner classes get instantiated with the outer one?

[river oracle]

No they aren't but they can use fields from their respective parent instantiation

[smoky oak]

hm

[hazy parrot]

public class Foo {
  private final int a;
  private final int b;

  class Bar {
    if (a == 2 ) {
        // you can access "a" here
    }
  }

  static class Bar2 {
    if (a == 2) { /*compile time error, "a" can't be accessed*/}
  }
}

[river oracle]

I'd give an example but I'm on my phone

[hazy parrot]

tldr to make instance of Bar you need instance of Foo

[smoky oak]

it can err

:kekw:

[hazy parrot]

there probably would be some comments if its not reliable lol

[smoky oak]

for the purpose here (ie, no inner/outer class crossing stuff), can i treat inner classes as if they're in a separate file? it's only to be used in the parent class

currently im just passing the required data on instantiation of the inner class in the constructor

[hazy parrot]

why not just use COUNT(*) for that ?

[river oracle]

You might actually benefit from a non static inner class here of it will never be used elsewhere

[smoky oak]

why?

like im genuinely curious

[hazy parrot]

not sure i understand

[smoky oak]

i just thought its to make code cleaner

[river oracle]

Because then you'd have no need got a constructor you can simply just use ghe fields

[smoky oak]

ah

the outer class is a class called by an event handler

[river oracle]

Ig I'd have to see the code

?paste

[undone axle]

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

[smoky oak]

the stacks basically this

Event
-> effectively static eventHandler method
   -> BukkitRunnable instance (of inner class of eventHandler class) for timed effect

[river oracle]

Yeah lemme see

[smoky oak]

https://paste.md-5.net/ufobebosos.java this the relevant part

the rest is just world scan stuff

actually those ints can probs be static

[river oracle]

Seems overcomplicated why can't this be done with a lambda and a util method

[smoky oak]

because with a lambda and util method it'll become one congested line of code and more importantly you cant debug lambdas

my priorities here are

1. can be tested
2. can be read
3. everything else

[river oracle]

You can debug lambda they give fine error codes

[smoky oak]

yea thats true but im not talking about that

[slender elbow]

this results in some very funny syntax when the inner class ctor is public new Foo().new Bar()/foo.new Bar()

[smoky oak]

im talking about that bug icon where you can go through ur code as it runs

which isnt available for lambdas

bc they get created at run time

like

[river oracle]

Debuggers people use those?

[smoky oak]

yea i do

helps out a lot too

[river oracle]

Wtf that's wild

[smoky oak]

half of this is math

so if i just get a black circle i ned to know when it fails

not just 'this block of 100 lines math failed'

[river oracle]

Ahh I usually just use unit tests makes sense

And sysouts

[smoky oak]

did that for a while, then i tried to get it to chat, then i gave up cuz that also took forever

[river oracle]

Otherwise yeah that should work though you can make ot non static

[smoky oak]

like is there an effective difference?

web says something about static nested classes not taking up memory

[river oracle]

Not really just is more logical considering your using it for botbing else

I'm sure theor are weird jvm quirks as always but I'm sure it's no big deal either way

Usually we're talking bytes of memory with those optimizations

[smoky oak]

eh tbf theres only going to be one instance of any of those at a time

[hazy parrot]

yeah List/Set definetly isn't a thing

[smoky oak]

it absolutely is a thing

its called serialization

u can just store it as blob

[hazy parrot]

nah i was just joking

because imo there is no need to return array here

[smoky oak]

btw

i have 2 runnables, 1st calls 2nd, 2nd needs a value from the code calling the 1st. should i pass it to the 1st runnable or do it some other way?

[slender elbow]

it definitely is, on intellij at least

[smoky oak]

didnt work for me when i tried it

🤷

[slender elbow]

¯_(ツ)_/¯

[smoky oak]

like the code ran for sure

[slender elbow]

half my current project is lambdas and I can confirm that the debugger works

actually I wonder how many indys there are on this project

[slate tinsel]

Hello! How can I cancel so that a hen does not spawn from a certain egg?

Which event are you thinking of? So when a player throws a special egg, this egg should not be able to spawn chickens

[scenic onyx]

how i can add tnt in head like tnt tag

[trim lake]

How to make CraftItemEvent work with shift click? If I set current item, it will set only first item crafted. Ex. If I craft 4 pieces of shoes, the item I set will be crafted only once (first item)

[storm crystal]

I just want to make sure, is this how I pass an instance made in main class to another class?

so that I'd be using the same instance in two classes

[candid galleon]

yep

[storm crystal]

okay thats good

managed to figure it out without any external help

[inner mulch]

im getting this error, i think i didnt close my connections properly, but even after restarting the db and my pc, it still says this.

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

[ivory sleet]

What operations r u doing

[smoky oak]

Collection<Entity> nearby = center.getWorld().getNearbyEntities(center.clone().add(0,radius,0),radius*2,radius,radius*2);
there a simpler way of doing this?

(values subject to change)

[ivory sleet]

Because I’m a bit lazy and busy rn ill just point you to the NQ model

[smoky oak]

oh ffs

im using list

[storm crystal]

how can I store ItemStack type in config?

[smoky oak]

ItemStack::getType and Material.getMaterial iirc

[storm crystal]

as in Material.getMaterial(AIR) for instance?

[river oracle]

either make a parser yourself or use ItemStack#serialize()

and add it to your config

[storm crystal]

Not really sure how to do it

[river oracle]

you got an itemstack ye

ItemStack blahblah = whatever;
Map<String, Object> configShit = blahblah.serizlize();
FileConfiguration myFunnyLittleConfig = stuff;
myFunnyLittleConfig.set("item", configShit);

conversely

ItemStack.deserialize(myFunnyLittleConfig.get("item");

[smoky oak]

hm. I want to apply a potion effect as if were the lingering potion on the ground (specifically instant damage) for faking a 3d effect cloud. Does anyone know the timing and damage value of lingering instant damage?
or if not where to find them? Googling only gives wiki entries which arent that useful

[storm crystal]

oh, I want to read it like that, so that I can read ItemStack from config when giving a certain item

[river oracle]

you're probably best off making your own parser then

also don't' prefix the materials with Material. in a config that's just terrible ux

your users will hate you

[storm crystal]

users of what

[river oracle]

the plugin

[lost matrix]

This looks like it has a few extra steps (just came here)

ItemStack item = ...;
FileConfiguration config = ...;
config.set("some.path", item);
// Later
ItemStack deserialized = config.getItemStack("some.path");

[smoky oak]

bold of you to assume i have users

[storm crystal]

yeah im not going to post any of my plugins public

nor my server will ever be public

[remote swallow]

still better to design it incase you werent using it

[river oracle]

you should always design with UX in mind

[storm crystal]

ux?

[river oracle]

User Experience

[storm crystal]

so I make it like that?

[river oracle]

oh my god

that is evne worse

do you hate yourself?

krystalowa:
  type: chest

what is wrong with this ^

why can't you just do that?

[lost matrix]

I would suggest not writing your config by hand. Write a class which generates you the default config.

[storm crystal]

here it saves item to some.path and that item is literally new ItemStack(Material.WHATEVER)

so why would it be ItemStack item = chest;?

[river oracle]

you can't load objects like that from a string

you need to first serialize then deserialize the configuration entry to do that for you

its not as striaght forward as writing the code in your config

[river oracle]

do you not write your configs by hand? I always do is there some reason you shouldn't?

[lost matrix]

new ItemStack(Material.WHATEVER) is calling a function and creating an object.
Its literally useless in a data standpoint

[storm crystal]

so I just do ItemStack chest = new ItemStack(Material.CHEST) and then use chest in config?

[lost matrix]

Preferably not. Just create a class BaseConfiguration, let it implement ConfigurationSerializable and throw it in a File when the server loads.

[storm crystal]

I am using configs with intention of manually adding new stuff fo them

[river oracle]

I write my configs in Json

[lost matrix]

Yeah that too XD
But json has no comments

[river oracle]

is there some actual advantage to doing so though? I always felt the starting values were rather arbitrary and hard coding htem has no specific benefit

[lost matrix]

And then i end up with meta information like that

[river oracle]

Usually I have a readme :P call me crazy but I like it

[glacial narwhal]

So, i restarted my server with my plugin and the plugin isn't on the server anymore, can anybody help ?

[lost matrix]

Stop the server, upload the plugin again, start the server

[river oracle]

must be another plugin trying to eliminate the competition. fr though ^

[glacial narwhal]

Doesn't change anything

[river oracle]

I think you have an error on startup

I'd put 2 cents on it

[lost matrix]

That is extremely unusual. Files dont randomly disappear.

[river oracle]

maybe if its some crappy panel or something its possible the panel is glitching out

[storm crystal]

would it be good enough?

[river oracle]

please no Material#matchMaterial

[lost matrix]

Is the File actually gone or do you just not see your plugin ingame

[storm crystal]

why

[glacial narwhal]

plugin in game

[river oracle]

reundant and inefficent

[storm crystal]

isnt switch case literally made to not make redundant stuff

[river oracle]

no not at all

[warm mica]

Imagine if you'd want to parse any material, your switch-case would get huge. There are just better and easier solutions with way less hassle

[lost matrix]

You can shorten this code and make it scalable

String typeName = lootboxConfig.getCustomConfig()... etc;
Material type = Material.matchMaterial(typeName);
ItemStack item = new ItemStack(type);

Now you support every item type there has ever been and will ever be.

[river oracle]

make sure to throw helpful errors if the type is null

[lost matrix]

Then you have an exception on startup. Send the error pls.

[slate tinsel]

Hello! How can I cancel so that a chicken does not spawn from a certain egg? So when a player throws a special egg, this egg should not be able to spawn chickens

Hey, there's the https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/event/entity/CreatureSpawnEvent.html and an EGG reason

[glacial narwhal]

[lost matrix]

Yeah fix that. There is no config.yml in your plugin.

[slate tinsel]

Checked it before, but can I retrieve the egg that the player shot somehow?

[storm crystal]

I literally checked if its null

and it still says that it can throw exception

[warm mica]

You can cast the Entity instance to "Egg" and use its getShooter method

[river oracle]

literally ignore intellij its so stupid

you should probably put that in a string variable

though

[glacial narwhal]

Yeah but doesn't it appear on run ?

[warm mica]

and getEntity() is the egg entity itself, if that's what you are looking for

[storm crystal]

sounds redundant to me

[river oracle]

its not

thats called you use it twice don't write the entire thing out twice otherwise its an eyesore. You have so much memory to use don't save it for something so dumb

[slate tinsel]

getEntity is chicken

[lost matrix]

I dont know what that means.
Your plugin doesnt have a config.yml file in it.

[warm mica]

Oh right

[glacial narwhal]

Does the custom configuration file get created on start* ?

[lost matrix]

https://www.spigotmc.org/wiki/config-files/

[warm mica]

Possibly ProjectileHitEvent could be an alternative

[storm crystal]

oh yeah any idea why this happens?

[river oracle]

dw about it bukkit auto adds a fallback

that's only there if another plugin has a command lootbox so your command can still be run

[storm crystal]

okay

[slate tinsel]

Have tested, entity.remove doesn't work but did you think like cancel event or something?

[warm mica]

I'd give cancelled a try, ye

[lost matrix]

Do you want to prevent spawning from eggs all together or only for certain players?

[slate tinsel]

I want to check if an egg has a certain nbt tag and make this egg unable to spawn chickens.

[young knoll]

There's an event for when a player throws an egg

That lets you set if it'll hatch or not

[slate tinsel]

PlayerEggThrowEvent

[young knoll]

yes

[icy beacon]

Well the value can technically be changed

So you've checked for null at some point but then magic happens and the value is not the same

Which is why you save it to a variable before doing the null check

Not only does it remove the possibility of the value being changed, it also makes your code more concise and readalbe

[storm crystal]

can I store list / array in config.yml?

[icy beacon]

Yeah

String List for example

[orchid gazelle]

hi, does anybody know a way to make the client update and start an Interpolation of a DisplayEntity at the same tick it is getting spawned?

[icy beacon]

abc:
  - hi
  - hello

getConfig().getStringList("abc")

[lost matrix]

As long as the objects in this list are primitive or ConfigurationSerializable

[storm crystal]

I just want strings and integers

[icy beacon]

Well yeah this should be fine for you

[storm crystal]

how can I access them in that case, do I just do this.that[0]?

[icy beacon]

list.get(index)

Have you worked with lists?

[icy beacon]

I mean this is valid in kotlin

[storm crystal]

yeah I just dont know syntax for configs in this case

[orchid gazelle]

if you try to do it on the same tick, by default, it just teleports without actually doing the Interpolation as defined

[inner mulch]

Is it possible to use player#setGliding(true), to let a player elytra fly without having an elytra?

[icy beacon]

List<String> myList = getConfig().getStringList("abc");
myList.get(1);
// in most use cases you don't get a certain item
// but instead iterate through the whole list
// but ofc i don't know your use case
// so do what you need to do

I think there's getList() that just returns a List<?> but I might be wrong

[lost matrix]

If you add any object to a config, then you should always load the whole object and keep it loaded.
Dont load the entire List and then only get one element from it. If you have to do that, then your design is faulty.

[young knoll]

Yes but you also need to cancel the toggle gliding event

[inner mulch]

im cancelling it but the player doesnt fly

am i doing something wrong?

?paste

[undone axle]

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

[inner mulch]

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

would this be correct?

[orchid gazelle]

alright, another question lol. How would I rotate an ItemDisplay so that it looks in the direction my Vector is going at?

[lost matrix]

The simplest way would be to let your spawn location have a direction

[orchid gazelle]

hmm, well I think that's hard to do

I am spawning my DisplayEntities based on a List of ProjectionPoints where I can calculate the Vector from

how can I apply this Vector to the Spawn Location as a Direction?

[lost matrix]

Vector vec = ...;
Location loc = ...;
loc.setDirection(vec);

[orchid gazelle]

doesn't the Length and so on matter when setting Directions?

[smoky oak]

no

world.spawnParticle(Particle.DUST_COLOR_TRANSITION,l,1,colors[colorCount]);
colors array of Particle.DustTransition
->
Particle DUST_COLOR_TRANSITION requires data, null provided
chat, am i stupid? Am i bad?

[orchid gazelle]

oh well then, imma try, thanks xD

[orchid gazelle]

alright so I tried doing that with:

    List<Location> projectionPoints = getProjectionPoints(handLocation, player.getEyeLocation(), player.getEyeLocation().getDirection());

        Vector dist = projectionPoints.get(projectionPoints.size() - 1).toVector().subtract(projectionPoints.get(0).toVector());

        // divide by bullet speed multiplicator
        int duration = (int) Math.round(dist.length() / 7);

        ItemDisplay bulletDisplay = player.getWorld().spawn(projectionPoints.get(1).setDirection(dist), ItemDisplay.class);

Direction still stays the same

[lost matrix]

Oh you want a projectile to follow a path?
In that case be prepared for a ton of math. Spigots methods might not suffice. You need to apply your
calculations on the transformation matrix.

[orchid gazelle]

well it's a straight raycasted line

and yes it has a LOT of maths for Intersection and stuff haha

[lost matrix]

Lets me see if i can come up with something real quick.
Do you want the movement along the line to be interpolated or do you plan on moving the object per tick?

[orchid gazelle]

the raycasting is also a custom implementation of an algorithm I wrote

[orchid gazelle]

the displayentity is using interpolation

I came across the issue that you have to wait 2 ticks after spawn for interpolations to work, but yeah imma try if it still looks fine with 100ms delay

[lost matrix]

Im guessing that you are calculating the interpolation duration via the distance?

[orchid gazelle]

yes

[lost matrix]

Ok let me play around for a bit

[orchid gazelle]

sure, take your time. Thanks a lot already!

[storm crystal]

how can I get just the PDC tag string value with given key?

I keep getting this

[glacial narwhal]

Configuration.get().addDefault("lava", true);
``` can any body say why this ```java
if (Configuration.get().getBoolean("lava")){
   p.getInventory().addItem(new ItemStack(Material.LAVA));
}
``` doesn't work

[sullen marlin]

I'm confused that screenshot is of a config not a pdc

[storm crystal]

its of console

[sullen marlin]

Depends entirely what Configuration.get is doing and what is in the config

[storm crystal]

I printed retrieved value of PDC

but for some reason

it prints that weird MemorySection thing

[sullen marlin]

I don't think the pdc can have a config

?nocode

[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.

[storm crystal]

...

[sullen marlin]

Nothing there prints to console

[storm crystal]

its in another method it doesnt matter

printing is for debugging purpose

[storm crystal]

the thing is that it prints this instead of just 'krysztalowa'

yesterday when I was working with PDCs there would be no issue

[sullen marlin]

If you have an issue with what is being printed we need to see the printing code

[storm crystal]

...

it literally

prints

[glacial narwhal]

sharpness on sword: 1
golden apples: 1
golden heads: 1
protection on chestplate: 1
protection on helmet: 1
sharpness on leggings: 1
sharpness on boots: 1
lava: true

[sullen marlin]

So Maybe you stored the wrong thing in pdc

Where is the setting code

[sullen marlin]

Lava can't be added to inventory in 1.13+

[storm crystal]

 NamespacedKey key = NamespacedKey.fromString("lootbox");
 lootboxMeta.getPersistentDataContainer().set(key, PersistentDataType.STRING, lootboxConfig.getCustomConfig().getString(MessageFormat.format("{0}", strings[0])));
 lootbox.setItemMeta(lootboxMeta);

[glacial narwhal]

It was that thanks

[sullen marlin]

Make sure you are testing a new item. You can use /data get to see what the PDC is

[storm crystal]

still same

[meager wolf]

how can i stop an item from dropping from player inventory when he dies

[sullen marlin]

Playerdrathevent.setDropItems or something

Look at the event methods / docs

[meager wolf]

there isnt a method for that

[smoky oak]

oh md if youre here, do you know where i can see the damage a lingering potion of harm deals? I'm trying to find the timings + damage but google only spits out the minecraft wiki and the api neither of which seem to have the numbers

[sullen marlin]

KeepInventory

[sullen marlin]

Isn't it based on level or something idk potions are confusing

[smoky oak]

the damage yes

but what's the timing?

eh ill just guess 1 second and 1.5 dmg

[grand flint]

hi cute @sullen marlin

[meager wolf]

oh

i see

my brain is not braining

[grand flint]

its the server that calculates light level right?

[sullen marlin]

Yes

[orchid gazelle]

md

when light level gpu acceleration?

when entity tick multithreading?

[inner mulch]

    public void onDoubleJump(PlayerToggleFlightEvent event) {
        Player player = event.getPlayer();
        if(player.getGameMode() != GameMode.SURVIVAL || player.getGameMode() != GameMode.ADVENTURE) {
            return;
        }
        
        if(player.hasPermission("Perks.perks.elytraPerk")) {
            event.setCancelled(true);
            player.setGliding(true);
            active.add(player);
            player.setAllowFlight(false);
        }
    }```

why does this event still fire even when the player is in creative mode?

[orchid gazelle]

because it's ToggleFlightEvent

when you hit double-jump in creative mode, you Toggle Flight

[inner mulch]

yeah but if(player.getGameMode() != GameMode.SURVIVAL || player.getGameMode() != GameMode.ADVENTURE) {
return;
}

[orchid gazelle]

well thats OR

[worldly ice]

Your game mode can’t be both survival and adventure

[orchid gazelle]

^

[inner mulch]

so i need there to be two statements?

this is a or statement

[worldly ice]

Just change your || to an &&

[orchid gazelle]

you need to use && instead of ||

yeah

[worldly ice]

Yeah

[inner mulch]

&& will make it worse ??

[orchid gazelle]

no

[inner mulch]

and means it needs to be those two

|| this is or

&& this is and

[orchid gazelle]

yes

[orchid gazelle]

it means that it needs to be NOT adventure mode and NOT survival mode

[worldly ice]

Well let’s says you are in survival mode. The left part of the or evaluates to true, but the right side evaluates to false

[inner mulch]

okay thank you

it works

[worldly ice]

So your code continues

[orchid gazelle]

your current code tells "it needs to be EITHER not adventure mode OR not survival mode" which is always true

[storm crystal]

So I made a custom simple lootbox plugin that takes into consideration adjustable odds, names and types in form of config,, is it any good looking?
https://paste.md-5.net/evafahiyeq.cs

[meager wolf]

im a bit confused, when u use getDrops() u get a Set<ItemStack> and when u use .clear() or .remove() u do that to the Set<ItemStack> copy u got in return not the original one that will actually get dropped,
so how are you stopping the item from getting dropped
is my brain not braining or its a a bukkit thing?

[river oracle]

Just Use PlayerDeathEvent#setKeepInventory(boolean flag)

[young knoll]

Pretty sure the list is mutable

[sullen marlin]

It's not a copy

[meager wolf]

i thought about doing something lik that, like keepinventory -> remove all items -> dropping all items in the coords where he died exept the specialItem

[meager wolf]

so if i edit it the original one will get edited too ?

[river oracle]

the list should be mutable then you can just remove them

[river oracle]

considering its mutable I'd say its more likely than not

[meager wolf]

ig i will try it and see what will happen

[sullen marlin]

Yes

[golden turret]

does it makes sense to put the @NonNull annotation in the Optional type?

[river oracle]

no

Optional implies the result will never be null

also why anotate WorldHud with NotNull when an Optional Implies it could be null

if it is true that WorldHud can't be null then an optional shouldn't be used at all

[golden turret]

the Optional#get() never returns null

if the value is null it throws an exception, yk

[ivory sleet]

thats fine

[river oracle]

seems redundant tbh

[ivory sleet]

it is

I mean mostly u prob wanna have a @NonNullByDefault or something wizardlybump

so u dont have to clutter it all with @NonNull

[river oracle]

WorldHud can be null though even if it throws the value itself could be null. I feel like that annotation would imply #get is a safe operation that won't throw

Those annotations are redundant as hell and confusing when surrounding an Optional

[lost matrix]

Finally found an affine transformation working for minecrafts scuffed coordinate system.
Lets hope the translation can just be done with a simple transformation composition.

Nah its fine. I got a new util method from this.

[river oracle]

hold up chat I'm doing like actual stuff with the world in my plugins for the first time in decades

    /**
     * Checks if an area around the provided location is free of obstructions
     *
     * @param center the block to use as the center point
     * @param width  the block area around the location.
     * @param height the height of the expanse
     * @return true if the space is clear of obstructions otherwise false
     */
    public static boolean isSpaceClear(@NotNull final Block center, int width, int height) {
        Preconditions.checkArgument(width % 2 != 0, "Width must be odd to have a center point");
        Preconditions.checkArgument(height > 0, "The provided height must be greater than 0");
    }

Basically goal is to implement and check if a set area around the center block is clear of obstruction.
Kinda need to check top left and bottom right or vise versa of an area and need to iterate through those blocks and see if they are not filled by other blocks.
What would I do to grab the top left and bottom right of the area though.

[orchid gazelle]

alright then

[river oracle]

wait I think I got it

holy cursed

        Block corner0 = center.getRelative(0, height, 0).getRelative(BlockFace.SOUTH, width - 1).getRelative(BlockFace.EAST, width - 1);
        Block corner1 = center.getRelative(0, height, 0).getRelative(BlockFace.NORTH, width - 1).getRelative(BlockFace.WEST, width - 1);

[lost matrix]

  public static boolean isSpaceClear(@NotNull final Block center, int width, int height) {
    Preconditions.checkArgument(width % 2 != 0, "Width must be odd to have a center point");
    Preconditions.checkArgument(height > 0, "The provided height must be greater than 0");
    int dw = (width - 1) / 2;
    Block upperCorner = center.getRelative(dw, height, 0);
    Block lowerCorner = center.getRelative(-dw, 0, 0);
  }

Ah height is not bidirectional for you

[river oracle]

oh shit I forget I ened the bottom corner on the second one

[river oracle]

yeah height only goes up

[river oracle]

what does getRelative(modx, mody, modz) do does it just get the relative displaced by x amount of cordinates

[worldly ingot]

Yes

[river oracle]

ahhh okay

[umbral ridge]

hey

how do you check if player isnt moving? with getVelocity?

[river oracle]

that'd be difficult to find out tbh because being knocked back or other things that indirectly move hte plyaer would be impacted as well

[umbral ridge]

I just need to check it when im executing a command

at one specific time

[river oracle]

then their velocity would be 0 as they're neither accelerating nor moving

well technically they could be accelerating with out yet affecting velocity, but that'd be very nieche. I don't know if that is possible in minecraft

[umbral ridge]

That?

[river oracle]

yeah pretty much

[umbral ridge]

Ok thanks

[deft thistle]

what if bro is riding a minecart is their velocity affected?

or a boat

[river oracle]

its affected

25% sure

[umbral ridge]

why isn't y in player's velocity 0 when standing still?

I dont have any potion effects applied or anything

I guess if y was 0 player wouldn't be able to jump? is that the jump "boost" value? or is that gravity?

[grim hound]

Because of how the Y velocity is calculated

yVel(t) = (yVel(t-1) - 0.08) * 0.98

[tepid ore]

This might be the wrong place to ask, but is it possible to customize a Spigot store page by using HTML?

[umbral ridge]

Thanks

[grim hound]

The 0.98 is a little bit off on some older versions but the general y Velocity is -0.0784 wjhen standing still

[storm crystal]

I thought its gravity

[grim hound]

This is the formula for falling

As there is no previous "off ground tick" (which is the "t")

https://www.mcpk.wiki/wiki/Vertical_Movement_Formulas

This is the recursive formula up until the 6th air tick

https://www.mcpk.wiki/wiki/Nonrecursive_Movement_Formulas

And here is 7+ air ticks

I find this a cool resource

[river oracle]

when working with a 3d array it goes like

int[x][y][z]

right

[young knoll]

If that’s how you ordered it then yes

[river oracle]

erm well I hope that's how I order it

Ig we'll see

[brittle geyser]

[brazen badge]

I need help creating a project. So, I want to create a config system like the mmoitems skills example:
ability1:
ability2:

and I want the plugin to detect that there is 1 or more abilities, which can be omitted from the config file. At the moment I want to create a system that through a file a user can create items (taken via id from the oraxen api) and that for each item there is an id and a boost value like "1.5". I would like the file to be structured like this:

items:
1:
oraxen-id: "test"
boost: "1.5"
2:
...
...

And that a user can add as many items as they want. Anyone know how to do it?

[tepid ore]

That is a lot of work, I'm making a similar project myself. I store a UUID in the item and connect that UUID to essentially a list of abilities via a hashmap.

Obv I use wrapper classes and have a custom made structure for it all, but essentially that is how I do it

[brazen badge]

butIf I create a class, with a constructor. And I run the constructor for how many items there are, changing the arguments inside it?

[tepid ore]

wdym you create a class with a constructor? You can might as well say you write code. Do you mean like a container class for a list of abilities?

[young knoll]

Why a uuid and not just a string

[tepid ore]

well it is stored as a string, but the string is a uuid

🤷‍♂️

[young knoll]

Yeah but you could just use a smaller string

Aka a unique name for each item

[tepid ore]

I could, but that would require that all names are unique. Say an admin made different loot box or whatever idk and wanted to call them all loot box or smth? It's dumb but they can. Also, using "invisible" uuids instead of customizable names allows me to guarantee that names do not clash or that dumb bugs appear

As all editing is done via GUIs (no configs ever) they don't need to know the uuid anyways so

[brazen badge]

just like this

[hazy parrot]

?conventions

[tepid ore]

It also improves performace? Although insignificantly. As the item id has to be linked to the corresponding list of abilities sometimes hundreds of times a second using .equals() on a uuid is faster than using .equalsIgnoreCase() on a string

[undone axle]

https://www.oracle.com/java/technologies/javase/codeconventions-namingconventions.html

[young knoll]

Why would you be using equals or equalsIgnoreCase

You’d be using map.get

[tepid ore]

Oh yeah, im dumb lol

[young knoll]

Well I guess that will technically use .equals, but yeah

[tepid ore]

Anyways, it seemed simpler to use an "invisible" uuid than a customizable name

The user can not see a difference, apart from the fact that there are no naming restrictions for the items in game

[tepid ore]

I have my plugin setup in a way that there are what I call scripts. Each item is linked to one or more scripts and when activated the script executes a list of abilities. So I'd suggest not doing what you've done here, and instead do a script class, map each id to a script or a list of scripts, and execute said script whenever you want them to

[young knoll]

I should make a yaml based scripting system

Everyone’s doin it these days :p

[tepid ore]

They are? 💀

[umbral ridge]

hey how do you get a direction to which player is facing? eg.: EAST, SOUTH-EAST, WEST, etc..

nvm I figured it out

[tepid ore]

Entity#getFacing right?

[young knoll]

Well somewhat :p

mmoitems items has theirs, eco has libreforge now

[tepid ore]

Well that's great

I did that before

But remade it to a GUI based pl

Was scared too many were doing yaml based

[young knoll]

I mean

You can always have a gui for the yaml

It’s nice to have the direct file option for power users, it’s usually a lot faster

[tepid ore]

Ig

[wet breach]

this is why ini files continue to be a thing

[golden turret]

I am writting a plugin where I need to check the player inventory before he drops an item. The problem is that in the PlayerDropItemEvent the inventory is already changed. How can I check the inventory before the change?

[tepid ore]

Wait, why are you doing this? Cant you use the item from the event and the slot index to backtrack it?

I thought the event was called before change but ig not

[glad prawn]

but why u put NonNull on everything lol

[grand flint]

Yeah literally

Just get the item(s) dropped

[tepid ore]

Or that if the slot is irrelevant ^

[golden turret]

I cant just use the item dropped

[tepid ore]

Why? This is kinda close to xy

What are you doing? Like what do you need it for?

[grand flint]

You are trying to get the inventory before the item is dropped

Get the inventory, add the dropped item to it

= You have the inventory before item is dropped

[thin iris]

omg

@young knoll

congrats

how do i. check the java version of my server

[ivory sleet]

java -version

iirc

[thin iris]

in console?

[ivory sleet]

but if on server, it should be at the start of the logs also, or maybe shown if u use like spark

yea

[slender elbow]

my favourite part about java -version is that -version and --version show slighlty different outputs

[tepid ore]

but why

[thin iris]

u sure?

[ivory sleet]

ah ur in the server

[thin iris]

i said console

[ivory sleet]

mye ma bad

[thin iris]

i’m able to access files tho

soo

does any1 know how to check

[glad prawn]

didnt your host let you choose your java version

[thin iris]

probably

but that was like.. 4 years ago

[slender elbow]

surely there's a setting for it somewhere

alternatively you can check the beginning of the server log

[thin iris]

oh thx

lemme check

[steady sentinel]

hi. what happened to the maven repository? why the snapshots repo no longer contains things like net.md5.bungeecord-chat? https://hub.spigotmc.org/nexus/content/repositories/snapshots/

there is something like https://hub.spigotmc.org/nexus/content/repositories/approved-sonatype-nexus-snapshots/, but it doesn't seem to work with maven either even though files seem to be there...

ok, with mvn -U it fetched the files from the "approved" thing. but I am still confused why is this a thing that's contradicting the docs like https://www.spigotmc.org/wiki/bbcode.8842/archive

[weak meteor]

Why @NonNull?

it can be null?

[grand flint]

Yeah what if they press q on an empty slot

[heavy mural]

Is there a way with nms packets to render an entity at the players y-level continuesly, without having to teleport that entity over and over?

Basically follow the up-and-down movement of a player

[remote swallow]

Non null is pretty much the same as not null

[weak meteor]

well its true

but a event can be null?

[remote swallow]

The instance inside a listener probably not but the nonnull is probably so someone doesnt call method(null)

[weak meteor]

K thx

Damn

[hybrid spoke]

ew new orange names

[inner mulch]

When I'm creating a class with methods how can i create methods with children, for example player.getLocation().getX()?

so that after 1 method i see more ?

[remote swallow]

they are good orange names

[rotund ravine]

Ohoh

[umbral ridge]

hey

what's a bigger operation, comparing Location's x,y,z and world variables or comparing an entire getLocation with other object

[rotund ravine]

Hello

How are you comparing them

[rotund ravine]

I mean location

also has pitch etc.

[umbral ridge]

playerStartLocation and player.getLocation(), Yeah pitch and yaw doesn't matter..

only x y z world

Should I write more code and compare these values instead?

[rotund ravine]

In recall

Good ol’ days

[umbral ridge]

The runnable is just for delayed teleportation

like a cooldown

[rotund ravine]

.getBlock().getLocation().equals

Ahaha

[umbral ridge]

I could use that

?

getLocation().getBlock() ? xD

[rotund ravine]

It’s an easy way

[umbral ridge]

doesnt that have to go through both location and block

[rotund ravine]

You can also just compare blockx y z and world

[umbral ridge]

Ok nice thx

[rotund ravine]

Or distance squared

Less than x

[umbral ridge]

would that be optimal

https://tenor.com/view/plink-cat-plink-cat-gif-1794292671885121408

[opal juniper]

Hmm, this seems like an xy, why do you need to be super efficient with this?

Comparing two locations with .equals is not that bad. It does depend on how much accuracy you need tho as they must be identical

[umbral ridge]

I like efficiency xD

[quaint mantle]

I doubt these have any impact on performance

[wet breach]

In order to compare location objects you need the xyz to be ints and not doubled or floats otherwise you will have lots of locations that wont match even if its essentially the same spot

[umbral ridge]

yes

getBlockX,Y,Z I've finished the class :D

[wet breach]

And if we are going to go that route i will turn these into binary and do a bitwise compare
