ChatListener

[tall dragon]

bruh

[eternal oxide]

delete line 21

[glad prawn]

    private LuckPerms luckPerms;
    private MiniMessage miniMessage;```

[polar forge]

It causes errors

[granite owl]

i only want it to not be modifiable

the encapsuled one

[eternal oxide]

use plugin.getLuckPerms() where it errors

[granite owl]

because thats supposed to be accessed via a setter

[glad prawn]

none are initialized

[polar forge]

The error is User user = luckperms.getUserManager().getUser(player.getUniqueId());

[tall dragon]

yea we know

luckperms is null

u set it in ur main class but not in the chat class..

[eternal oxide]

plugin.getLuckPerms().getUserManager()...

[polar forge]

So I should remove everything after the = and rip lace it with what Elg said?

[tall dragon]

no

replace luckperms with what elgar said

[eternal oxide]

User user = plugin.getLuckPerms().getUserManager().getUser(player.getUniqueId());```

[tall dragon]

🥄

[polar forge]

Ok done

[polar forge]

Spoonfeeding yummy

Should it work now?

I’ll test it

Anything else?

ElgarL, anything else should be added?

[eternal oxide]

no

[polar forge]

Ok boss

[glad prawn]

bro cannot distinguish between declaration and initialization

[granite owl]

hope this isnt too ugly to read xD ```java
public Boolean setKeySeperator(Character keySeperator)
{
if (keySeperator == null) return false;
if (keySeperator.equals(this.settings.valueSeperator)) return false;
if (keySeperator.equals(this.settings.commentDeclarator)) return false;

    this.settings.keySeperator = Character.valueOf(keySeperator);

    return true;
}

[tall dragon]

why Boolean

[rapid vigil]

bro read my mind

[granite owl]

returning if it was set or not

[tall dragon]

but boolean exists

[remote swallow]

why not primitive

[tall dragon]

no reason to not use primitive as far as i can see

[slender elbow]

java is an object oriented language

gotta use all the objects

[tall dragon]

hmmmm

a good point!, a good point

[granite owl]

i just wanted to keep it consistent since im also working with strings and primitive strings as char* do not exist

[glad prawn]

charAt(0) 💀

[granite owl]

what

[tall dragon]

that doesnt make much sense

[polar forge]

Bruh I still don’t see any Prefixes I set on LuckPerms

Why is that

[eternal oxide]

You don;t set any

[polar forge]

At least I don’t get any errors in my console

[eternal oxide]

you only change colour based on permissions

[polar forge]

Well I have the permission for color

But I don’t have any color

[eternal oxide]

ah you do set PlayerListName

[granite owl]

annoying that java doesnt have a built in ini parser, always json and xml..

[polar forge]

Is that wrong?

[eternal oxide]

which name are you trying to modify?

[tall dragon]

i mean. it does have .properties support

which is bassically the same thing

[polar forge]

Users’ names

If anyone has a prefix

[eternal oxide]

to display where?

[polar forge]

In chat

To everyone

[granite owl]

ill check it

[eternal oxide]

then add the prefix to the display name

[polar forge]

To every else if statement?

[granite owl]

this never sounds good to my ears

[polar forge]

Yea I never use switch

[granite owl]

and why is that

[rapid vigil]

I want the ability to hear text too

[granite owl]

and taste colors?

[polar forge]

I prefer else if

[granite owl]

the more branches you have the more overhead you get unlike with a switch

if you have a definitive amount of possibilities almost always use switch xD

or recursion

I don't know what the problem is...
I've tried switching to 1.20, re-reading the manual and fixing it... I still get the same error.

Where did i go wrong?

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

[remote swallow]

run buildtools for 1.20.2

[polar forge]

Yea I don’t always have so many else if statements

[granite owl]

i stopped hardcoding most stuff anyways and write generic functions reading from config files

[polar forge]

To every else if statements? In the brackets before ChatColor?

[granite owl]

and theyre either plaintext like xml, ini or serialized

[polar forge]

Oh nice

[eternal oxide]

use a StringBuilder to save you repeating code

[granite owl]

what was the recoomended api again?

the one someone released under MIT license which is an AST parser for mathematical expressions

forgot its name

[polar forge]

Nah it’s not a problem to repeat, but im making sure the position of the prefix

[young knoll]

Crunch?

[granite owl]

that one

[polar forge]

Before ChatColor?

[tall dragon]

crunch is gpl-2.0 tho ;d

not mit

[granite owl]

it says mit

[tall dragon]

yea nvm

im confused with somethn else

mb

its mit indeed

[granite owl]

there aint no way im writing my own ast parser xD

[tall dragon]

why not. its fun

[granite owl]

because i suck at math

xD

[tall dragon]

well thats generally where the computer comes into play

[granite owl]

and im not writing my own compiler either

[granite owl]

but how do i explain the operations if i dont even know how the math behind it works because i dont understand the derivation

[tall dragon]

i mean surely you understand the basic math rules?

[granite owl]

for the most part xD

[tall dragon]

it really is a fun challange to make a basic expression parser

though if u need something full fledged i would definately go with crunch

its very nice

and fast

[granite owl]

i want to define constant strings with variable names and replace them at runtime with values

then feed them to the parser

[tall dragon]

well crunch supports that

iirc

[granite owl]

yea ill prob go with that one

[tall dragon]

yea u can do that with an EvaluationEnvironment in crunch

[granite owl]

more importantly i have default arithemetic operations that are always the same thus constant, and user input to add to that term

[tall dragon]

soo a custom function?

[granite owl]

no

via a GUI

[dawn flower]

use evalex

[proud heart]

thanks

[granite owl]

hm

[tall dragon]

not entirely sure what u mean by this then

[polar forge]

@eternal oxide Btw, Nop still doesn’t work

[pliant topaz]

When I set PersistentData, is it only for that specific item, or for all items which are excactly like that item? (so same metadata etc)

[tall dragon]

only for the one u set it to

which means its now different to the "identical" ones

[pliant topaz]

okay, thought so, then something in my code just isn't working haha

thx for the help

[dawn flower]

if minecraft is able to identify new items why dont they make a way to identify duped items without giving up stacking items

[swift slate]

looking for experienced dev need something good made

[remote swallow]

?services

[undone axle]

If you wish to request or offer development/art/building/administration services, please do so at https://www.spigotmc.org/forums/services-recruitment-v2.54/

[dawn flower]

wrong channel

[shadow night]

because difficult

[swift slate]

dont have the effort to login their website

[remote swallow]

you dont need to login

find someone offering development services

[dawn flower]

then how does minecraft identify each item for pdc

across restarts as well, there must be an identifier or smth

[shadow night]

pdc is a little isolated container inside the nbt data of the item

[dawn flower]

ah

[shadow night]

when an itemstack is duped, it's no different than calling new ItemStack and then adding on the same nbt data, ofc you could use that to identify duped items, but it'll be wacky with stackable items

[dawn flower]

would be cool if we had setStackable, ik this would break stuff but maybe we could also have getStack which returns the array of items in that itemstack

[river oracle]

that's the thing though minecraft can't just identify new items

[river oracle]

setMaxStackSize should work

[dawn flower]

crap i meant forceStackable

if u have 2 items with different pdc data but both r force stackable they would stack

[river oracle]

that would not work out well tbh

there are so many logical what ifs I can't even start

[tall dragon]

that would require a complete rewrite on how the item system is handled

[river oracle]

not just that too it would require a rewrite of how we identify items in hands too. It'd make detecting if a player is holding an item a literal nightmare

[dawn flower]

not really, they would only need to modify 'force stackable' items

no need to mess with the current item system

[tall dragon]

currently an itemstack is stored with an amount

that woulnt be possible

since nbt is potentially different

[river oracle]

I don't think you're really thinking about how this would have to be implemented in NMS

[high arrow]

Hello, I have a problem concerning plugin messages ( again... )

I tried getting the player count of a server, but it doesn't work well, it says there is 68k players online, + papi has errors in the console because of this ( i have the bungeecord expansion )

LISTENER

@Override
    public void onPluginMessageReceived(String channel, Player player, byte[] bytes) {
        if(!channel.equalsIgnoreCase("BungeeCord"))
            return;

        ByteArrayInputStream in = new ByteArrayInputStream(bytes);
        DataInputStream stream = new DataInputStream(in);

        try {
            switch (stream.readUTF()) {
                case "PlayerCount":
                    PlayerCount = stream.readInt();
                    break;
            }
        }catch (Exception e){
            e.printStackTrace();
        }
    }

SENDING

public int getCount(String server){
        ByteArrayOutputStream b = new ByteArrayOutputStream();
        DataOutputStream out = new DataOutputStream(b);

        try {
            out.writeUTF("PlayerCount");
            out.writeUTF(server);

        getServer().sendPluginMessage(this, "BungeeCord", b.toByteArray());
        return listener.PlayerCount;

[dawn flower]

u never wrote int here?

[high arrow]

but bungeecord has to

?paste

[undone axle]

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

[high arrow]

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

example of the bungeecord expansion:

switch (in.readUTF()) {
        case "PlayerCount":
          if (stream.available() == 0)
            return; 
          server = in.readUTF();
          if (stream.available() == 0) {
            getPlaceholderAPI().getLogger().log(Level.SEVERE, String.format("[%s] Could not get the player count from server %s.", new Object[] { getName(), server }));
            this.counts.put(server.toLowerCase(), Integer.valueOf(0));
            break;

[solemn meteor]

in PlayerSwapHandItemsEvent, how do I get which hotbar slot I swapped with

I assume thats what the event does

[young knoll]

It swaps main hand with offhand

So the main hand is your currently selected slot

[blazing ocean]

just do enums at this point

[dawn flower]

for some reason when i try to strike lightning it just strikes it for a tick

entity.getWorld().strikeLightningEffect(new Location(entity.getWorld(), coords[0], coords[1], coords[2]));

[oak mica]

Hi, I set the value of a NBT tag here:

        container.set(Data.SUMMONING_MOB_UUIDS.key, PersistentDataType.STRING, "abc");

but when I try set the value again

        ItemMeta meta = stack.getItemMeta();
        PersistentDataContainer container = meta.getPersistentDataContainer();
        String uuids = container.get(Data.SUMMONING_MOB_UUIDS.key, PersistentDataType.STRING);
        if(uuids == "abc") uuids = String.valueOf(entity.getUniqueId());
        else uuids += "," + entity.getUniqueId();
        container.set(Data.SUMMONING_MOB_UUIDS.key, PersistentDataType.STRING, uuids);
        stack.setItemMeta(meta);

I get a error

Caused by: java.lang.IllegalArgumentException: The found tag instance (NBTTagByte) cannot store String

[dawn flower]

?

[high arrow]

solved

[dawn flower]

???

[rapid vigil]

Use EntityDamageByEntityEvent and check if both are a player, if so then teleport the one who got damaged to the spawn location

[vague dawn]

when the y is <=80?

[rapid vigil]

if you want to

[vague dawn]

hmm

[dawn flower]

?????

[vague dawn]

is there a way how to get the killer?

[dawn flower]

Entity#getKiller

[chrome beacon]

That event would be too early for that

[rapid vigil]

Use EntityDeathEvent then?

[vague dawn]

well, you just said this

[young knoll]

You can't teleport in the death event

[chrome beacon]

Respawn the player the next tick and then teleport them

[young knoll]

Just get the damger in EntityDamageByEntityEvent?

[chrome beacon]

or that ^^

[vague dawn]

and i do not want the player to be dead, i want to get the damager and if the damager equals "killer" and the player y <= 80 then telepor the player

[chrome beacon]

depends on how much compatability you want

[young knoll]

And check if the targets current health - event.getFinalDamage <= 0

aka it kills them

[dawn flower]

fourth ??

[quaint mantle]

Hello, anyone knows how to send an action bar message to a player?

[dawn flower]

Player#sendActionBar

[rapid vigil]

we're not paper tho

[dawn flower]

Player#spigot

[young knoll]

Player#spigot#sendMessage with ChatMessageType.ACTION_BAR

[dawn flower]

player.spigot().sendMessage(ChatMessageType.ACTION_BAR, component here);

[rapid vigil]

and NMS in older versions :)

[chrome beacon]

Make sure you're testing on Spigot

[dawn flower]

i am

[shadow night]

what does /version say

[dawn flower]

1.20.4

[shadow night]

what exactly does it say

[young knoll]

That's not an output of /version

[dawn flower]

u want a pic?

[shadow night]

yes

[dawn flower]

aight

[vague dawn]

hmm, i have tried it like this, but not wokring

there is nothint like player.getDamager

[chrome beacon]

?

[rapid vigil]

its event.getDamager

[chrome beacon]

^^

You already have the killer

also that will cause an error when damaged by an entity that isn't a player

[vague dawn]

yes, but how to chesk it in the if ?

[chrome beacon]

You don't need to check if the killer is the killer?

you already know it is

[quaint mantle]

what is component here? shouldn't i put the message?

[dawn flower]

text component isnt a string

[chrome beacon]

https://www.spigotmc.org/wiki/the-chat-component-api/

[rapid vigil]

why does Entity#getKiller return a player, does that mean you can never get a zombie killer?

[vague dawn]

why killer.. i am not talking about killing

[chrome beacon]

What are you talking about then?

[chrome beacon]

Not from that method

[slender elbow]

you named the variable killer

lol

[young knoll]

They aren't tracked the same way players are, no

[vague dawn]

i do not need the killer... i just want to teleport the player if his y <= 80 and get lasthitted by damager

[shadow night]

I read that as lastshitted

[rapid vigil]

ooh alr

[quaint mantle]

ty

[vague dawn]

so i came out with this:

but its not working

[rapid vigil]

I actually dont understand what you are trying to make

[chrome beacon]

Why do you have the second part in your if statement

[dawn flower]

/ver isnt working

[chrome beacon]

/version

[dawn flower]

nvm fixed it

[vague dawn]

hm.. its true, i do not need it i guess

but i need to know the last damager before the player teleport

[young knoll]

The last damager is the damager in the event

[delicate lynx]

then just use damager

you already know who did the last damage

[vague dawn]

true

[polar forge]

Guys

[vague dawn]

but its still not teleporting the player when his y <= 80

[polar forge]

So I got this problem, I still can’t see the LuckPerms prefixes I set, when I load my plugin

[rapid vigil]

are you sure your world spawn is even set?

[young knoll]

It’s always set

Lul?

[rapid vigil]

don't you need to run /setworldspawn

[young knoll]

No

[vague dawn]

its set

[young knoll]

Where do you think players spawn when you don’t run that?

[rapid vigil]

they don't spawn at all

[dawn flower]

now what

[young knoll]

Ah yes of course

[dawn flower]

its been 45 minutes

[young knoll]

Are you using some weird client

Or any client mods tbh

[dawn flower]

me?

[vague dawn]

but the problem is still with the teleportation

[young knoll]

Yes

[dawn flower]

no

doing it with something /summon works

[young knoll]

Interesting

Does calling strikeLightning also work

[delicate lynx]

you're listening on the wrong event

that won't run for void damage

[dawn flower]

no

[vague dawn]

why void damage.. i do not need void damage

[dawn flower]

both strikeLightningEffect and strikeLightning die after a tick

[young knoll]

They don’t even take damage in that video

How are you expecting the damage event to fire

[sullen canyon]

Hello, I am making a minigame and I want to send different messages to players, my current system looks like

Classes:
SkywarsPlayer
- GameSendingMessageService
- ...other services related to players/games

(Some of the messages include calculating top 3 killers, or displaying new statistics to the player in chat and some of the messages are just 2-3 lines simple messages)

I am pretty sure it's a poor designing way and it could have been improved. In my GameSendingMessageService class I have 10-15 methods to send different messages (I attached the picture). What could I change to make the system more flexible and well designed? How do you usually do this?

[rapid vigil]

i think he doesn't read what he's writing

[vague dawn]

well

[brittle geyser]

RTX 4060 TI OMG

[vague dawn]

whats with that xd?

[dawn flower]

4060 isnt that expensive

well its expensive but not like a 4090

[brittle geyser]

i have only 3060

[dawn flower]

my guy i have 128mb vram

perfectly fine

[vague dawn]

you can see on the video, igor get hitted by entity and still doesnt teleported him

[sullen canyon]

im on rx570 4gb 😭

[chrome beacon]

👀

[rapid vigil]

did you register the event?

[chrome beacon]

Bro running a GPU from 20 years ago

[vague dawn]

yes

[delicate lynx]

EntityDamageByEntityEvent only fires when a mob attacks another mob. you're checking if their location is <=80, which will only run while they are down in the void below and get hit by another player

[shadow night]

You guys got graphic cards?

[shadow night]

Mine is called intel integrated graphics

[dawn flower]

normal settings 32x texture pack

[rapid vigil]

no 80 is not below void, he was also at Y 20 in the vid

[young knoll]

You’d need to check the last damage cause if you want to handle the void damage

[quaint mantle]

sorry for the ping. Do you know how to change the duration of the message?

[dawn flower]

u dont

[delicate lynx]

sorry, saw void, still

[dawn flower]

u can spam send tho to make it longer

[delicate lynx]

that event is not what you want to achieve this

since it will only listen for when the player first gets hit, not when they fall

[young knoll]

Normal damage event -> check if lastDamageCause instanceOf entityDamageByEntityEvent -> check if the damage in said event is player

[rapid vigil]

PlayerFallEvent and then if y is less than 80 :>

[vague dawn]

true, tested it

it telepor tthe player only when i hit him when hes under 80

[young knoll]

Or you can use the move event instead of waiting for them to take void damage

If you prefer

[quaint mantle]

isn't there another vway

[dawn flower]

only for titles iirc

[dawn flower]

53 minutes have passed

[muted otter]

how do teams work with scoreboards?

[young knoll]

Not sure why the methods would be broken

[dawn flower]

teams != scoreboard

[muted otter]

wdym?

[vague dawn]

yep, working, thx

now i need to check, if there was damager or not xd

[young knoll]

Create a bug report with a minimum reproducible example if you can verify it’s a spigot issue

[delicate lynx]

are you telling it to lightning strike for more than one time

[vague dawn]

thx guys

[eternal oxide]

have you tried modifying the returned LightningStrike Object?

[dawn flower]

yes

getLifeTicks returns 2 btw

[eternal oxide]

so set it longer and see what happens

also increase flashes

[dawn flower]

i tried to make it 15

[eternal oxide]

the life ticks is only how long it will cause damage for

flashes is how long it displays

[dawn flower]

ah

how many flashes is the default

[eternal oxide]

probably 1

[delicate lynx]

docs says 1 to 3

[oak mica]

holla i tried to set the value of a NBT tag then change it later

to originally set it i use this

        container.set(Data.SUMMONING_MOB_UUIDS.key, PersistentDataType.STRING, "abc");

to change it i use this

        ItemMeta meta = stack.getItemMeta();
        PersistentDataContainer container = meta.getPersistentDataContainer();
        String uuids = container.get(Data.SUMMONING_MOB_UUIDS.key, PersistentDataType.STRING);
        if(uuids == "abc") uuids = String.valueOf(entity.getUniqueId());
        else uuids += "," + entity.getUniqueId();
        container.set(Data.SUMMONING_MOB_UUIDS.key, PersistentDataType.STRING, uuids);
        stack.setItemMeta(meta);

thenn i get this error

Caused by: java.lang.IllegalArgumentException: The found tag instance (NBTTagByte) cannot store String

anyione know how i can fix this

[eternal oxide]

that can;t be all the code

[oak mica]

wym

[dawn flower]

seems normal

[oak mica]

        SUMMONING_MOB_UUIDS(NamespacedKey.fromString("overcharged:summoning_cooldown_ultimate")),

this is the value

[eternal oxide]

3 is max, so if you want it to strike longer you have to spawn is more than once

[oak mica]

oh nvm your not tlaking to me

🔥

[eternal oxide]

sorry 🙂

[dawn flower]

tfdym, adding 1 more wont make it from 1 tick lifespan to like a second

[oak mica]

nah im being dumb sorry

[eternal oxide]

If you want it to flash lightning for a second you have to fire it more than once

[dawn flower]

wouldnt that just create abunch of lightning bolts

[eternal oxide]

just make the additional hits cause no damage

yes, you delay them

[dawn flower]

ugh

[eternal oxide]

thats how a lot of things in MC work, like sounds

[vague dawn]

one last question - how to reset the damager after the teleport?

[dawn flower]

well for whatever the damn reason skript's lightning works perfectly AND THEIR CODE IS THE SAME AS MINE

[young knoll]

I think there’s a setLastDamageCause

[vague dawn]

there is

but what to put there

[delicate lynx]

it's deprecated lmao

[dawn flower]

my code: entity.getWorld().strikeLightningEffect(entity.getLocation());

their code: lastSpawned = l.getWorld().strikeLightningEffect(l);

and their code works

so its def not spawn abunch of lightning

[young knoll]

Mmm so it is

I guess it would be better to track the last damager yourself then

[vague dawn]

thats impossible, i want to give the damager some items, so i need to reset it, bcs when player next falls on their own, there would still be the last damager right?

[young knoll]

Yes

[dawn flower]

so i did some debugging

[young knoll]

Also wdym that’s impossible

[dawn flower]

and found out a plugin is killing it

but idk which plugin

[vague dawn]

like i do not want it

[young knoll]

Binary search time

[tardy delta]

what about using ResourceBundles

[dapper flower]

How do i turn on a redstone lamp?

[young knoll]

getBlockData -> cast to lightable -> setLit -> setBlockData

[dawn flower]

do i seriously have to disable each plugin one by one to check

[young knoll]

That’s what the binary search is for

[dawn flower]

i hate my life

[dawn flower]

wdym binary search

[oak mica]

scratch this its the container#get t hat for some reason errors

im so confused

[young knoll]

Disable half
If it goes away:

• switch to the other half and check again
• repeat process
  if it does not go away:
• repeat process

[dawn flower]

i always do that

[tardy delta]

congrats you invented binary search

[dawn flower]

anyways i found it first try

i should go try my luck with a lottery ticket before my luck is gone

[young knoll]

Literally what I am describing

[tardy delta]

tried to be funny

[dawn flower]

hahaa

that wasnt funny

can u make effect lightning have sound

[young knoll]

Just play the sound

[dawn flower]

what is the sound

[quaint mantle]

What is the equivalence between ticks and seconds?
1 second = ? ticks

[young knoll]

20

[dawn flower]

1 second = 20 ticks

[young knoll]

(By default)

[dawn flower]

basic knowlage

[quaint mantle]

what in the world in spigot drinking

"2" is a number

[slender elbow]

"2.0" is not an integer

[young knoll]

It’s not an int

It’s a float/double

[dawn flower]

oh shit im parsing int

[remote swallow]

oi nerd

read dms

[dawn flower]

who split numbers to be double and int 😭

just make it one number class that support both

[young knoll]

Computers

[dawn flower]

computers only understand binary, binary can be converted to decimal directly

not integer and decimal

[young knoll]

What

[tardy delta]

what

ever heard of ieee754

[dawn flower]

java can just compile '3' as 3.00 and '3.69' as 3.69

[tardy delta]

whats that supposed to mean

[dawn flower]

theres no point for integer

double cna be an integer

[tardy delta]

performance?

[dawn flower]

good point

but isn't 3.00 = 3

how does that affect performance

[slender elbow]

floating point precision goes brrrr

[tardy delta]

your questions dont make sense at this point

[dawn flower]

it does

[young knoll]

I can’t think of any language that doesn’t separate floating point and non floating point

[dawn flower]

just make computers better

what's so hard abt that

[dawn flower]

python

[tardy delta]

JAVASCRIPT

[eternal oxide]

there was a time we didn;t have FP processors

[young knoll]

Those are both weakly typed

[dawn flower]

and java isn't?

[oak mica]

holla i tried to set the value of a NBT tag then change it later

to originally set it i use this

        container.set(Data.SUMMONING_MOB_UUIDS.key, PersistentDataType.STRING, "abc");

to get the current value

        ItemMeta meta = stack.getItemMeta();
        PersistentDataContainer container = meta.getPersistentDataContainer();
        String uuids = container.get(Data.SUMMONING_MOB_UUIDS.key, PersistentDataType.STRING);

thenn i get this error

Caused by: java.lang.IllegalArgumentException: The found tag instance (NBTTagByte) cannot store String

anyione know how i can fix this

[tardy delta]

good ol time with bcd

[young knoll]

No lol?

[dawn flower]

at least u dont need to call THREE methods / fields for a simple print

[young knoll]

?

[tardy delta]

thats type erasure mate

[dawn flower]

System.out.println
^ ^ ^

[young knoll]

Oh no

[tardy delta]

lol

[young knoll]

Whatever will we do

It’s still 2 in js

[tardy delta]

println in kotlin

[remote swallow]

system is a class, out is a variable

[dawn flower]

doesnt count

[tardy delta]

could static import System.out and now you have two

[dawn flower]

too bad proper optional args arent made

[tardy delta]

we have kotlin for that

[dawn flower]

doesnt count

[young knoll]

I agree overloading is kinda meh

But it’s not a huge deal

[dawn flower]

its not a huge deal until u have a 100 line method and u need optional args

have fun dealing with that

[tardy delta]

just write your own lang

[young knoll]

?

[slender elbow]

wouldn't be an issue in kotlin

[young knoll]

Its not really a huge issue in java

[dawn flower]

this is a java argument not a kotlin argument

[young knoll]

You just add an overload

It’s like 3 lines

[dawn flower]

ugh

serialization

is bs in java

[tardy delta]

as in the reflective approach?

[slender elbow]

wouldn't be an issue with kotlinx.serialization

[tardy delta]

lucky you that you arent using c

[dawn flower]

u cant make an object without calling the constructor

[tardy delta]

you can

do some research

[dawn flower]

which makes it pain to serialize

[dawn flower]

u need unsafes

which isnt safe

[tardy delta]

so what

[dawn flower]

tfdym so what

when was the last time u saw java being used outside of minecraft

[tardy delta]

unsafe doesnt mean its unsafe

[slender elbow]

wouldn't be an issue with datafixerupper

[tardy delta]

it means that it isnt made fool proof for idiots

[chrome beacon]

Java is used quite a lot

[dawn flower]

in?

[tall dragon]

Intellij ? XD

[chrome beacon]

Backend systems

[young knoll]

Believe it or not code is used for more than just games

[chrome beacon]

^^

[blazing ocean]

🤯

[dawn flower]

no way

[eternal oxide]

lies

[chrome beacon]

Java isn't exactly used for frontend stuff

[dawn flower]

dead srs?

[echo basalt]

Binance's entire backend is made in java p sure

[blazing ocean]

but yeah it is also used for (kinda legacy) android dev

[echo basalt]

There's vaadin for frontend

[blazing ocean]

since kotlin is mainly used for mobile dev now

which is good

since multiplatform is really enjoyable to work with

[quaint mantle]

^ need help and it’s a lot so I’m just sending link, here’s a quick rundown…

“For the people who don't watch the video, when looking straight up in the air and tracing a ray from the players eyes, it will return that result.getHitBlock().equals(block) stating that the block that was being broken is the same one the ray was looking at.”

[dawn flower]

oh wait this is supposed to be a helping channel

[blazing ocean]

yes...

[dawn flower]

cough

[quaint mantle]

cough

[dawn flower]

cough

[tardy delta]

generate the bytecode

[quaint mantle]

if (block.getType() == Material.AIR) return;

I don't think it would have anything to do with this but that's the only thing I can think of since the player is looking in the air

Reel

[tardy delta]

there are differnt types of air

[dawn flower]

??

[tardy delta]

Material::isAir

[quaint mantle]

Huh 😭

[quaint mantle]

What

[blazing ocean]

null

[quaint mantle]

There are different materials

[young knoll]

There’s 3 airs

[quaint mantle]

What are they?

Water

Fire

[tardy delta]

cave, void and normal iirc

[quaint mantle]

wtf is cave

And is void all of the air under the void or is it the air section that you take damage from? Probably the second one

If you don’t understand it just watch the video

[young knoll]

Anything out of the world is void air

Caves are filled with cave air

[quaint mantle]

Wait the video didn’t process bruh

Here’s the video showing the issue^

Well here v

Hello, I've got an error with my BlockPopulator code:

public class RocksPopulator extends BlockPopulator {
    @Override
    public void populate(@NotNull WorldInfo worldInfo, @NotNull Random random, int chunkX, int chunkZ, @NotNull LimitedRegion limitedRegion) {
        if(worldInfo.getEnvironment() != World.Environment.NORMAL) return;
        int randomX = (int) (random.nextDouble()*16*chunkX);
        int randomZ = (int) (random.nextDouble()*16*chunkZ);

        System.out.println("chunkX " + chunkZ);
        System.out.println(randomZ);
        System.out.println("perfectY " + perfectY);

        Switch button = (Switch) Material.STONE_BUTTON.createBlockData();

        button.setFacing(BlockFace.UP);

        limitedRegion.setBlockData(randomX, randomZ, perfectY, button);
    }
}```

Do someone know how to fix that?

[quaint mantle]

Why is it called clazz?

[blazing ocean]

clazz has been used in Java in place of the reserved word "class" since JDK 1.0. "class" is what you want, but abbreviating or inserting junk ("a", "the", "_", etc) reduces clarity. clazz just says class. "International" English speakers (those reading both British and American English) are used to transposing 's' and 'z'.

[quaint mantle]

Oh kk

[quaint mantle]

“For the people who don't watch the video, when looking straight up in the air and tracing a ray from the players eyes, it will return that result.getHitBlock().equals(block) stating that the block that was being broken is the same one the ray was looking at.”

Here we go the video loaded

[blazing ocean]

interfaces or interfaces-kotlin for kotlin

[lost matrix]

Dont apply illegal values on your BlockData. Just as the error suggests in plain english.

[quaint mantle]

I don’t think they know where or what the illegal value is

[cinder abyss]

exactly

[eternal oxide]

setting in a LimitedRegion you shoudl use relative coords

[cinder abyss]

what's the formula for relative coords?

I'm so sorry 😭

[quaint mantle]

Bro omg wrong dang video

[blazing ocean]

lmfaoo

[cinder abyss]

what is illegal value?

It's just a switch blockData?

[quaint mantle]

Anyone know this issue?

“For the people who don't watch the video, when looking straight up in the air and tracing a ray from the players eyes, it will return that result.getHitBlock().equals(block) stating that the block that was being broken is the same one the ray was looking at.

if (block.getType() == Material.AIR) return;

I don't think it would have anything to do with this but that's the only thing I can think of since the player is looking in the air”

[eternal oxide]

a LimitedRegion is 0-15 +/- getBuffer()

[cinder abyss]

getBuffer?

oh okay I see

[eternal oxide]

of the LimitedRegion

[cinder abyss]

yeah

[young knoll]

Use setAttachedFace not setFacing

[quaint mantle]

“if (block.getType() == Material.AIR) return;

I don't think it would have anything to do with this but that's the only thing I can think of since the player is looking in the air” 😭

[eternal oxide]

that too, for your other error (coll's post)

[cinder abyss]

okay thanks

[lost matrix]

Any exceptions in console?

[quaint mantle]

Nope

[cinder abyss]

how can I do a plus minus?

[quaint mantle]

For the rest of the code it’s here: https://www.spigotmc.org/threads/raycast-returning-incorrect-multiple-blocks.644537/

[lost matrix]

It should. If you ray trace and hit nothing, then your result is null

[eternal oxide]

um, math!?

a Chunk is 0-15 size, then a LImited region has a buffer around it of x size

[cinder abyss]

yeah but, I've learned sinus, cosinus and tangent this year, sooo for more advanced math...

[quaint mantle]

Ok. In my code, I have if (result != null && result.getHitBlock() != null && !result.getHitBlock().equals(block)) { // ! Right here is the issue !

Btw I’m guessing that’s the issue

Most likely is

[eternal oxide]

ok, get a random between -getBuffer() and 15+getBuffer

[quaint mantle]

Omfg

[cinder abyss]

oh okay thanks

[quaint mantle]

Bruh

Don’t say it don’t say it

[young knoll]

I mean, the buffer is there for big things

[quaint mantle]

I’m so stupid lmao

[young knoll]

You should only get a random from 0-15

[eternal oxide]

true

[young knoll]

The other chunks will have their own calls of the populator

[quaint mantle]

Thank you! It was because I was making sure it wasn’t null

[eternal oxide]

as it's a chunk populator

so do just 0 to 15

[cinder abyss]

okay

so only that, nothing more?

[quaint mantle]

Bro someone add a Minecraft heart emoji 😭

[neon shoal]

Hey where can I find the docs?

[eternal oxide]

you are only placing a single block so no need to cross chunks

is there a way to set specific permissions to a player? like i set the permissions in the plugin.yml like this:

i want that one player can have the permission command.settings how can i set the player permission for that.
here is the code how i try to set the permissions:
https://pastebin.com/MZeLK4kp

[sullen marlin]

Code seems fine?

[copper scaffold]

But i can‘t use the command when im not op

[young knoll]

You might have to refresh commands?

[cinder abyss]

Hello, I get Coordinates 24, 22 are not in the region for java int randomX = randomBtw(random, -limitedRegion.getBuffer(), 15+limitedRegion.getBuffer()); int randomZ = randomBtw(random, -limitedRegion.getBuffer(), 15+limitedRegion.getBuffer());

Please, Is there a way to fix that?

[sullen marlin]

Read the docs

[cinder abyss]

okay thanks

so without buffer?

I'll not send you what they'll send to you

Idk about regex sorry

[slender elbow]

just parse manually 💀

[echo basalt]

Yeah p much

that regex is trippy

[cinder abyss]

is there really regex optimization?

there is a real performance impact with regex?

[muted otter]

How do I make a scoreboard that can update its values? Like player health for example

[young knoll]

There’s a performance impact on my eyes

Same error, Coordinates 27, 42 are not in the region

int randomX = randomBtw(random, 0, 15)*chunkX;

I think this isn't the good formula, but I can't find the good one

not sure, code looks fine

are you sure you arent setting it somewhere else also

if that really is all the code, create a test plugin and open a bug report

[ionic terrace]

I know with the server version of minecraft the minimum java version is 21 but does this apply to plugins as well?

[young knoll]

The minimum is still 17 until 1.20.5 comes out

The api also uses 17 now

[ionic terrace]

I know but when it comes out, do I need to change to Java 21?

Not at the moment

[young knoll]

If you use NMS you probably will

Otherwise no

[ionic terrace]

Cool thanks!

Is there a good way to hide the text on the scoreboard that comes from registering a new team on a line?

Team line = scoreboard.registerNewTeam("" + i);

Because right now I have the index numbers from my foor loop next to my text. I do not want any text related to the for loops at all on the scoreboard, but I need to have the index there to see what line it is.

[young knoll]

Add the hover and click to the middle one

And then append them together

how do i check if the top of a door is gone

so like half

check if block above is not door

if not door, not door

if door, door

how do i get above?

[vast ledge]

y + 1

Block doorBottom = YourSource;
Location doorTopL = doorBottom.getLocation().clone().add(0, 1, 0);
Block doorTop = doorTopL.getBlock();

[muted otter]

Yes

[waxen parrot]

Why can I not get the default commands like /me, /tell, etc to work on my default rank?

[muted otter]

what commands does the default group have?

which ones cant you do

[waxen parrot]

well, for starters I just added: minecraft.command, minecraft.command.help, minecraft.command.tell, and minecraft.command.me to see if they'd work and which they don't when applied.

It just pops up saying "Do not have access to that command".

I have the prefix and everything set

[muted otter]

try to look at the web editor and double check everything

also I think this is supposed to be in #help-server

[waxen parrot]

I figured development, since i'm developing my server atm. but idk, all this channel topic stuff is confusing. It's spigot related technically lol

[muted otter]

ye ik lol

sometimes can be hard to understand

basically #help-development is for making plugins and #help-server is for plugin help

[waxen parrot]

ah gotcha

I will head there then. still haven't been able to figure it out lol

[muted otter]

accept my friend req

[deep herald]

cause u have essentials

anyone know why this is happening?

nvm im just gonna use adventure

[worldly ingot]

Only reason it's doing that is because you're toString()ing the component instead of sending it as a component

Is the location object the same mutable as the player object?

this will be bad if i will save location in some object class?

[sullen marlin]

I don't understand

[lilac dagger]

player extends Object like every class java has

[mild pecan]

does anyone need a plugin made im bored asl 😭

[nova notch]

chatgpt yourself some ideas

[charred blaze]

can i somehow force player to press f3+d?

[quaint mantle]

Nope

[charred blaze]

:(

[quaint mantle]

Debug is 100% client bound

[charred blaze]

debug?

thats chat clear iirc

[lilac dagger]

Just send 30 empty messages

[charred blaze]

about that

for (Player player : Bukkit.getOnlinePlayers()) {
System.out.println(player.getName());
player.sendMessage(color(message));
}

when im doing this

its spamming console too

and broadcast method doesnt work for legacy color codes

[lilac dagger]

Maybe it's the color

[drowsy helm]

System.out.println(player.getName());?

[lilac dagger]

What's with the sout?

[drowsy helm]

that will print to conosle

[charred blaze]

just trying to debug

i know

[drowsy helm]

and just use Bukkit.broadcastMessage

[lilac dagger]

When you send a message to a player it can't send it to the consoke too

[drowsy helm]

if you're gonna send to all

[quaint mantle]

Client doesnt accept null/empty strings

[charred blaze]

^

[drowsy helm]

ah

[lilac dagger]

Add a space

[charred blaze]

??

[lilac dagger]

It works

[charred blaze]

where

[lilac dagger]

In the message

[charred blaze]

in the color() method?

[quaint mantle]

Add &f to empty message

[lilac dagger]

Player send message (" " )

[charred blaze]

ok ill try

well its still spamming in console

Bukkit.broadcastMessage(" ");

this one

for (int i = 0; i < 600; i++) {
Bukkit.broadcastMessage(" ");
}

nvm fixed

[lilac dagger]

600 is a whole lot by the way

Put it to 30 or 50

[rough drift]

Thoughts on passing a plugin to a constructor vs calling an internal method whenever the object is registered?

[glad prawn]

wat

[quaint mantle]

does 2nd one inject plugin using reflections?

[blazing ocean]

or if using a resource pack, you can create a custom character with an empty bitmap which is huge and "clears" the chat

[still ridge]

Hello, I'm making a plugin in 1.20 and I was wondering if it was possible to make custom enchantments or if I really had to use PersistentDataContainer?

[vast ledge]

You cant exactly "Make enchantments"

You have to add the lore, yourself

usualy, you can read the lore, to confirm what enchants the item has

[still ridge]

ok and to store the enchant I need to use PDC

How I can remove the italic text effect on the lore ?

[clear elm]

how can i pin a line in inteliJ ultimate?

Use '§r' then '§e' I think
§r = Reset
§e = Yellow

[tardy delta]

searching for files can be time consuming
heh? crtl-n?

[ocean hollow]

Why can't this code teleport?

[tardy delta]

where are you calling that

[tardy delta]

uh not sure

[warm mica]

Is the location printed as intended? Maybe a plugin is blocking the teleportation

[warm mica]

I miss the bird

[ocean hollow]

    public String toString() {
        return "x = " + x + "; y = " + y + "; z = " + z + "; yaw = "  + yaw + "; pitch = " + pitch + "; world = " + world + "; server = " + server;
    }```
```    public Location getLocation(){
        return new Location(getWorld(), x, y, z, yaw, pitch);
    }

i checked player, and it's not null

[warm mica]

You would have a NPE in that case

My bets are that some plugin is blocking PlayerTeleportEvent if the console is clear

[ocean hollow]

wth, I tried it via tp and it works.

player.performCommand("execute in minecraft:overworld run tp @s " + sL.getX() + " " + sL.getY() + " " + sL.getZ() + " " + sL.getYaw() + " " + sL.getPitch()); like

but this option doesn’t suit me, how can I do it through Player#teleport?

[sullen marlin]

Seems like world is the issue then?

[ocean hollow]

no

the names of the worlds are the same.

[warm mica]

Listen to PlayerTeleportEvent with MONITOR priority and check whether it is cancelled

[proper cosmos]

Guys, In PlayerDeathEvent#getPlayer() returns player that died, and PlayerDeathEvent#getEntity()returns entity that killed player?

[rapid vigil]

No, they're both the player that died

[ocean hollow]

it doesn't output anything.

[proper cosmos]

Ye. I've also discovered that. I've read that Player#getKiller() will work?

[warm mica]

Are you in a vehicle (horse, minecart ...)?

[ocean hollow]

no

[rapid vigil]

yeah that will get the player's killer

[proper cosmos]

Okey, thanks

[rapid vigil]

yw

[warm mica]

That is weird then. #teleport only returns false if:

• You are dead / don't exist anymore
• You have no connection (NPC)
• You are inside a vehicle
• The PlayerTeleportEvent got cancelled

[echo basalt]

ignoreCancelled ?

[warm mica]

Update your java & buildtools

[echo basalt]

java 8 for 1.15.2

hm

[summer gale]

ya

[ocean hollow]

I'll probably need to create a command for something like this, do it via performCommand, and give permission at the time of use

[summer gale]

still same problem after updating. The gui one gives the same error on startup

[warm mica]

Are you talking about this? I'd have taken the time to check which of the conditions I have listed actually causes it. But if you still want to go that route, you may also try to use Bukkit.dispatchCommand(Bukkit.getConsoleSender(), "..."))

[warm mica]

Although I am not very sure how well that works with vanilla commands

[warm mica]

Download and install java 21 or 17

[summer gale]

those don't work for 1.15.2

[warm mica]

1.15.2 is a very odd version to use, why specifically that one? If you still want to use it, copy and google the second line of the error message

[warm mica]

Although they should work with java 17 just fine, I believe?

[summer gale]

nope

[oak mica]

i double checked i dont change that nbt tag or get it anywhere else apart from one function which has the same code so where do you make bug reports

[cinder abyss]

Hello, I want to place buttons on the ground, how can I rotate them in different direction, while still being on the ground?
They are actually like that:

[ocean hollow]

lol, even if I use command - it still not teleport

[cinder abyss]

And I want them to be in both direction, like that

(I'm using Switch for BlockData)

[echo basalt]

Fun thing

display entities can be rotated with yaw and pitch

on top of their rotation matrixes

[cinder abyss]

yeah

but

[blazing ocean]

this is such an awesome api feature

because the rotation is a pain to figure out without axiom

[cinder abyss]

you say that for me?

[trail coral]

what would i use reflection for?

[cinder abyss]

accessing net minecraft server classes

[trail coral]

why would i need that tho

[cinder abyss]

editing minecraft at the root basically

adding mob, editing AI, adding biomes...

[trail coral]

oh alr thanks

[summer gale]

Could someone help please

[summer gale]

.

[icy beacon]

You aren't limited to just NMS with reflection. You can call methods by just their name and the class' name, or you can get/set variable values just by their name, even when they're private, etc. Reflection is a compile-time unsafe coding tool

I personally use it to parse my locale files. I go through every message key and match it to a variable name in my Messages class

[ocean hollow]

please help 😦

[trail coral]

thank you

[trail coral]

why are you even making that command tho

[ocean hollow]

so it doesn’t matter whether through or without them - the same thing.

[warm mica]

Are you using spigot/paper or some other fork? Maybe it has some built in feature

[ocean hollow]

paper

[summer gale]

am i allowed to ping?

[lost matrix]

What are you trying to do?

[ocean hollow]

upon receiving a message from velocity, teleport the player to the point that was received. I get the correct location and the player is normal. But for some reason Player#teleport does not work

[ocean hollow]

checked via Player.performCommand("execute in minecraft:overworld run tp @s x y z yaw pitch") - works there.

[lost matrix]

So performing the command works but teleporting the player via code doesnt?

[ocean hollow]

It only works through vanilla /tp, but not through mine. The problem is in Player.teleport()

[summer gale]

Hollup

Java 22?

when did this happen

[lost matrix]

That sounds weird. Do you get an exception when you call teleport? What happens?

[ocean hollow]

i have no errors

[lost matrix]

Show your code and debug it

[ocean hollow]

?paste

[undone axle]

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

[lilac dagger]

Do you have a sneak peek into how you do this?

[ocean hollow]

https://paste.md-5.net/ebucakufit.java - MessageListener
https://paste.md-5.net/jesosijaxo.java - VelocityMain
https://paste.md-5.net/kixejayosa.java - VelocitySpawnCommand

ServerLocation is not null, and has valid data. Player is not null, because I don't get NullPointerException

and the player is definitely not dead, and not on the entity

[lost matrix]

Print out sL.getLocation()

[lost matrix]

Hm. Try teleportAsync() instead

[echo basalt]

sounds like a paper method

[lost matrix]

The only thing that comes to mind if this doesnt work is someone cancelling the teleport event

[ocean hollow]

still doesn't work

[ocean hollow]

how can I check this?

[summer gale]

Just asking, where is the ServerLocation class from?

[lost matrix]

Listen to the teleport event with MONITOR priority and check if the event is cancelled

[ocean hollow]

second screen

and it outputs nothing

[lost matrix]

So you are telling me that you call Player#teleport(Location), and there is no exception, nothing is happening on the server and the event isnt fired?

When are you sending the message from velocity to the server?

[ocean hollow]

Yes, a debug message appears in the logs, but Player.teleport() will return false if checked

after the player has fully logged in. ServerPostConnectEvent

[sullen marlin]

?jira

[lost matrix]

Probably a custom one

[undone axle]

https://hub.spigotmc.org/jira/secure/Dashboard.jspa

[lost matrix]

So... the player isnt even properly spawned on the server yet.

sigh

[ocean hollow]

the only event after which at least a message is sent

I tried it through ServerConnectedEvent, and it still doesn't work

[oak mica]

ty

[ocean hollow]

I tried to make a delay, launched teleport a second after the message arrived

[lost matrix]

I should have asked what your initial intent was...
Ok here is what you do:
Before the player connects, you send a PM to the server he is connecting to.
The server then stores this in a Map<UUID, ServerLocation>.
Then you listen for the PlayerSpawnLocationEvent, get the location from your Map, and set the Location in your event.

[ocean hollow]

I was told that I cannot send a message if there are no players on the server, so I first throw the player there, and then send teleport messages.

[lost matrix]

Is this for a public project?

[ocean hollow]

only for my server

[lost matrix]

Why do you need the proxy to tell the mc servers where to spawn a player?

[ocean hollow]

I have two separate servers and need to create a way to move between them. For example /home, /tp, /warp, ...

For example, spawn is in Locations, and survival is in Kingdoms. and I need /spawn

if there was Player.teleport in velocity it would be easy, but otherwise I have to worry about messages

[lost matrix]

Ok, i personally would just use Redis for this because communication through the proxy sucks big time.
But you need to send the message from your proxy to the server before the player spawns but after he is connected.
Then listen for the PlayerSpawnLocationEvent and set the location there. Dont call player.teleport() for this.

[thorny radish]

Does anyone know how to create an NPC when you right click the NPC it will open a gui, with a bunch of multiple quests, like "deliver 30 stone blocks" "deliver 8 diamonds" etc when you're done with all of them you can rankup

with bossshop plugin maybe? if its possible

[smoky anchor]

Seems like #help-server question

[ocean hollow]

I was told about using Redis, RabbitMQ, but I have no idea how to work with it. Not only are there 0 guides about Velocity, but even more so about using them with velocity.

[lost matrix]

Doesnt matter what you use Redis with. Its the same for any java application.
Create one Redis client for your application when it starts:

RedissonClient redisson = Redisson.create(config);

Subscribe to a certain topic on one application:

// Get the topic
RTopic topic = redisson.getTopic("teleports");
// Register a listener on that topic
topic.addListener(String.class, new MessageListener<SomeObject>() {
    @Override
    public void onMessage(String channel, String message) {
        //...
    }
});

Send messages to the topic from another application. Everyone listening on this topic will receive the message:

// Get the topic
RTopic topic = redisson.getTopic("teleports");
// Send a message to the topic
topic.publish("Hey there. Everyone gets this.");

Its literally like this for any java application. Doesnt matter if its a web server, Velocity or Minecraft.

[cinder abyss]

Hello, how can I do a BlockPopulator before tree generation?

[lost matrix]

What do you need this for? I think you might need to change the order of populators since trees are also generated using a BlockPopulator.

[cinder abyss]

I need this to generate some stone buttons at the ground, but when there is a lot of trees, the highest block is often a leaf, so I want to avoid that by populating with stone buttons before trees instead of checking the root of the tree and place a button next to him or something like that

It'll be much faster

[lost matrix]

I would def argue that scanning an entire tree to find their root is way, way slower than just going from the highest block downwards to check where the ground starts.

1. Get the highest block
2. Check if its leaves
3. Iterate down until you hit the ground (Maybe stop early at 60)
4. Place a button

[cinder abyss]

yeah I though of that too

well, let's do that

I might ask for more help later with optimization btw

[lost matrix]

PS you can also just use a normal Database that isnt Redis for this.
Just write to the DB, wait until its done, connect the Player to the other server, read the value in the AsyncPlayerPreloginEvent into a Map
and use this value in the PlayerSpawnLocationEvent

[ocean hollow]

Velocity doesn't seem to have a regular driver for MySQL

[lost matrix]

Velocity doesnt need to interact with your DB for that

[ocean hollow]

like, create command in bukkit plugin, and everything else through velocity, and then back?

[ocean hollow]

wait, teleport didn’t work there for me, even if I was already on this server.

[lost matrix]

This is all really convoluted. You might also just shade a sql driver in your velocity plugin.

[ocean hollow]

And to use Redis, do I also need to host it, just like hosting a database?

[proper cosmos]

Guys, I need help. Is there any way to retrieve Potion's duration from ItemStack? All I got so far is getting PotionMeta but this doesn't give any way to retrieve duration. I've tried potionMeta.getCustomEffects() but this is just empty

[river oracle]

That means it has no custom effects use get the potion type

You'll need to manually do getPotionEffects on that and grab the duration

[lost matrix]

PotionMeta ->
getBasePotionType() -> PotionType
getPotionEffects() -> List<PotionEffect>

Then check duration and amplifier from those effects

[oak mica]

PotionMeta.getBasePotionType().getPotionEffects().forEach(effect -> {
  int ticksDuration = effect.getDuration();
});

[proper cosmos]

Oh, I've must missed that. Thanks guys ❤️

[orchid iron]

i have a feature that places a 3x3 area of farmland and crops on top whenever a player places a farmland block.
It works fine but i have different unlockable crops and a few of them are corals: Whenever a player places farmland the corals on top will spawn but the center one will break instantly. Does anyone know how i can fix that? I can send a video via dm if you want

[astral pilot]

yo does Server#addRecipe() conflicts with other plugins?

because for some reason my plugin's custom crafting recipe wont work if there's another plugin that also uses Server#addRecipe()

[young knoll]

As long as your recipe has a unique key it should be fine

[astral pilot]

It does tho. but why is the crafting output not showing

whenever there's another plugin that is using that method

[cinder abyss]

so, I sent in #1100941063058894868 this 👍 thanks for your help (and time!)

[lost matrix]

Sounds like the other plugin might just remove the recipes

[cinder abyss]

Hello, is block PDC (by mfnalex) available on world population (with BlockPopulator)?

[eternal oxide]

no as it uses the chunk not a LimitedRegion

[cinder abyss]

okay thanks

[eternal oxide]

you can;t use teh Chunk before it's populated

[cinder abyss]

then I'll revert what I want to do

[lost matrix]

What are you trying to do?

Why do you need a persistent medium while generating anyways?

[cinder abyss]

check if a stone button is a rock (so a block placed on world gen) and if it is, then I don't drop it on break

so I'll invert that, and make the button without PDC and the buttons placed by players have a PDC

but, for compatiblity...

so, any idea?

[lost matrix]

Invert it or store the block in memory and only use the PDC when a chunk is (un)loaded

[cinder abyss]

let's invert it then

thanks

[dawn flower]

does this give support for skript addon development or spigot only

[glad prawn]

spigot

[dawn flower]

goddamn it

[lost matrix]

This is what you get when asking for skript support

[dawn flower]

not skript support, skript addon development support

[glad prawn]

the same

[dawn flower]

skript addon development = spigot

How i can add the enchant glowing effect on a item without necessarily enchanting ? (1.20)

[grim hound]

I'm kinda confused at the java.lang.reflect.Proxy class

[grim hound]

cuz I thought I'd be able to intercept method invocations on an instance

but it ain't that simple

[slender elbow]

it just creates an instance on a set of interfaces and it delegates to you the method calls, that's all

[lost matrix]

Only possible by adding an enchantment to the ItemStack and then hiding it with the enchantment hide flag

[slender elbow]

or by waiting until 1.20.5 comes out

[dawn flower]

or adding a null enchant

[dawn flower]

(i think it gets removed on server restarts)

[slender elbow]

or by setting the enchants list in nbt to an empty list

[dawn flower]

same thing

[grim hound]

I don't get the list of classes thingy

[lost matrix]

PS: Laplace transforms > Euler-Lagrange for second order differential equations imho

[dawn flower]

where do i get the upcoming stuff like knowing that in 1.20.5 there'll be an option to force glint

[still ridge]

and how i hide the enchant ?

[slender elbow]

by reading mojangs changelogs?

they publish one with every snapshot/pre/rc/release

[dawn flower]

im reading em rn

[slender elbow]

or in the Minecraft wiki for 1.20.5,

[dawn flower]

there isnt anything abt glints

[lost matrix]

There is an ItemFlag you can add to your ItemMeta. Something ItemFlag.HIDE_ENCHANTS

[grim hound]

like will it delegate the call to my interceptor to all instances created of the classes I give?

[slender elbow]

yes there is, with the whole item components changes

[dawn flower]

mojang needs to add a way to remove this

looks shit

[still ridge]

I've just been thinking, I'm just stupid I'd forgotten x), thx

[slender elbow]

no, all it does is it creates a class that implements the interfaces you give it, and your invocationhandler will be given all the method calls

[remote swallow]

1.20.5

[dawn flower]

what the fuck is a vault

[slender elbow]

just disable it? it's in your client lol

[remote swallow]

iirc

[slender elbow]

F3 H or whatever

it doesn't show by default

[dawn flower]

by that logic everything can be disabled in ur client, why code a minecraft plugin

[grim hound]

what if I just wanted to intercept the calls to a singular object instance and delegate it to the original source if it isn't the method I want

[dawn flower]

u can hide unbreakable yet there's still an itemflag

[slender elbow]

?

[grim hound]

internet says ByteBuddy

but it'd enlarge my plugin quiet a bit

[slender elbow]

of some random existing object in some random variable somewhere? no

[dawn flower]

1.20.5 does everything i ever needed in life

when is 1.20.5 releasing

[grim hound]

not

[remote swallow]

this week

[grim hound]

variable

[dawn flower]

oh no

[slender elbow]

Proxy is only useful for interfaces, you'd have to replace a field somewhere

[grim hound]

I can do that
