[quiet ice]

You can, but you should not

[lost matrix]

Just... go to releases and download this

[mild cloak]

i already downloaded

[lost matrix]

Then throw it into your project and build an artifact

[mild cloak]

but its only a library

Ok

[quiet ice]

ALTERNATIVELY, use spigot's libraries feature

Given that it is on mavenCentral, that should work if you are on an up-to-date version

[mild cloak]

I'm on version 1.20.4, how can I call the function

[lost matrix]

Which one?

[mild cloak]

in maven give me this error when i try install

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

[rare rover]

erm, does anyone know why my compound interest ain't working correctly?

    private fun getEnchantCost(currentLevel: Int, increaseLevel: Int): Double {
        val increase: Double = enchant.getIncreaseProgression() / 100
        val initialCost: Double = enchant.getInitialCost()
        val totalLevel: Double = (currentLevel + increaseLevel).toDouble()

        return initialCost * (1 + increase).pow(totalLevel)
    }```
1 = 1.1K
5 = 1.1K
25 = 1.2K
50 = 1.4K

[mild cloak]

fastboard

[lost matrix]

If you use maven, then dont add any jars to your project manually

[mild cloak]

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

i make this

to install .jar

[lost matrix]

[mild cloak]

idk i see in internet

[quiet ice]

If you intend to build this plugin a year or two, I urgently recommend to not use system, it is deprecated for removal

[mild cloak]

what i use? provided?

[quiet ice]

provided and hunt down the repositories in which the dependencies are included in

[mild cloak]

you can send me a example?

[quiet ice]

https://mvnrepository.com/artifact/net.luckperms/api/5.4 for luckperms, for example

[lost matrix]

Does getIncreaseProgression() return 0.0 - 1.0 or 0.0 - 100.0?

[mild cloak]

but some plugins dont have this

[rare rover]

currently its returning 0.5

for 0.5%

[quiet ice]

EZRanksPro probably does not have a repository attached - in that case you need to use the classic mvn install:install-file [...] workaround most people here can tell you more about (I use another workaround but can't be bothered to explain that one)

[quiet ice]

Vault is also available via maven, though only via the jitpack repo

[grizzled cedar]

Hi @eternal oxide ! I develop my plugin that changes player skins and use your code of PlayerSkins. All works perfectly on player join, but when I try to update player skin on another event it takes 30 secs to load and it loads first layer only. Can you please give me some advice what should I do next, I'll be so grateful

[eternal oxide]

First layer only means you didn;t se the correct flags.

Probably something up with your EntityDataPacket

[lost matrix]

I mean your values look completely fine to me

Why do you think its not working?

[mild cloak]

i dont see any tutorial to use mvn install

[rare rover]

well i'm adding 0.5% (0.005) each time, and those numbers are so close together. Should i increase the progression?

[grizzled cedar]

thanks a lot

[rare rover]

1 and 5 shouldn't have the same value

[lost matrix]

0.5% isnt much

[rare rover]

hmmm

let me increase ig maybe

[lost matrix]

The exponential growth properly kicks in around lvl 220

[rare rover]

hmm let me increase it to like 1%

the problem is that the max value will be like 25K

should i use a different algorithm? Im calculating the enchant cost, without having to loop

and i came across compound interest

ig it would be fine since i kinda do want it kinda easy at the start then get harder the more you play

[icy beacon]

does it ever happen to anybody that your ssh connection just goes on a disconnection spree

like i connect, i do stuff for 20 seconds and it disconnects me

and that happens like 10 times

then it stabilizes again

happens at random points in time

i'm not too bothered by it and i'm not gonna try to fix it unless someone actually has encountered such a problem and knows what exactly why it is & a solution

[quiet ice]

https://blog.jeff-media.com/manually-installing-jar-files-to-your-local-maven-repository/

[mild cloak]

i already try but say .jar dont have pom.xml

@quiet ice

https://i.imgur.com/X8YnB51.png

[quiet ice]

the pom is irrelevant, the maven artifact resolver still works with just the jar in place

(hence why this is still just categorised as an INFO)

[mild cloak]

give me the same error

Cannot invoke "java.io.File.mkdirs()" because the return value of "java.io.File.getParentFile()" is null

[quiet ice]

What is the full stacktrace?

And where exactly does this error occur?

Assuming this happens while executing maven's package goal - are you using IJ's built-in maven integration or are you using the system's maven installation? If latter, how did you install it - manually or via a package manager? Does the maven local repository exist under %userhome%/.m2/repository?

[mild cloak]

Can you tell me how I can put text with RGB changing color effect?

[quiet ice]

```<language>
<code>
```

But that is irrelevant for stacktraces. There generic code blocks or a plain paste suffices

[grim hound]

How can I have a plugin start with root permissions?

[quiet ice]

root permissions as in ?

[hazy parrot]

Run server with root perms

[grim hound]

root

system

perms

[hazy parrot]

Altrough there is probably no reason to do it

[quiet ice]

Why on earth would you want that

[grim hound]

I need it

[hazy parrot]

You most likely don't

[grim hound]

ignorant

[hazy parrot]

It's aways better to give correct permissions then just toss in root

[grim hound]

what if somebody has a server on a hosting and doesn't have access to the server starting file?

[quiet ice]

Regardless, you can only start individual processes as the superuser - nothing else

[hazy parrot]

?

[grim hound]

I meant to say that you were

ignorant

[quiet ice]

So what you are asking for is a privilege escalation exploit?

[grim hound]

uh

no

[quiet ice]

which you generally need multiple of

[hazy parrot]

Don't see how, but okay ig, gl

[rough ibex]

I see absolutely 0 reason to need root permission.

[quiet ice]

Well that specific example is attempting to making use of a software vuln

[grim hound]

I just need access to the iptables

and I need root perms for that

but ofc, all of you are quick to judge

[quiet ice]

Well that is an appropriate use

[grim hound]

(or ignorant)

[rough ibex]

You should have opened with your purpose

[kind hatch]

^

[grim hound]

no

[rough ibex]

instead of just asking how to do something that is indeed, dangerous

inherently

[grim hound]

I was taught here to not state what I'm doing unless absolutely necessary

[kind hatch]

Well, you were taught wrong.

[grim hound]

mmm yes, amma hack

[rough ibex]

I feel that virtue was self-taught.

[grim hound]

so, how can I do it?

[rough ibex]

sudo

[kind hatch]

Compromising system security should always be a red flag.

[rough ibex]

sudo iptables ...

[quiet ice]

Won't work lol

[grim hound]

/\

[rough ibex]

because

[quiet ice]

That would be a free privilege escalation exploit right there

[rough ibex]

They seem to want to ignore those

[quiet ice]

Of serious magnitude even

[kind hatch]

iptables sounds like you're trying to mess with a ban plugin of some sort, but we wouldn't know since you won't tell us what you need access to that command for.

[rough ibex]

serious XY problem here

[grim hound]

firewall

[kind hatch]

wut?

[grim hound]

if you're not gonna help then shut it

[rough ibex]

I did

[quiet ice]

I mean you could set the executable bit for the iptables wrapper script to allow non-root access (so something like 777, but I am not sure if that even works)

[rough ibex]

It likely wouldn't

[grim hound]

every info on the web that I found

tells me I need root perms

[rough ibex]

and they are correct

[grim hound]

for any iptables interaction

[kind hatch]

I know a solution to his problem, but idk if I want to say it.

[young knoll]

Is it time for plugins with ring 0 level access

[kind hatch]

Depends on if he already has root access to begin with.

[quiet ice]

Apparently you can also modify the /etc/sudoers file to whitelist some wrapper script so it has superuser perms

[grim hound]

well depends

but lets say that yes

[kind hatch]

Depends....

[grim hound]

on who uses the plugin

[rough ibex]

why exactly does this need to be a plugin

[grim hound]

I can always just tell the user to start this file for extra performance

[quiet ice]

If the JVM process is executed as root you can execute the iptables command with no problems

[rough ibex]

if this is like a fail2ban type thing

[grim hound]

this very thing interacting with the firewall does not

but it would be an addon to the plugin

to have the firewall be extra fast

[rough ibex]

microoptimization

[grim hound]

(really necessary, like there's some great exploits)

[grim hound]

bro stuf

[hazy parrot]

Just run server as root

[grim hound]

you don't even know why I want to do it

[kind hatch]

But we do.

[rough ibex]

no, because you won't tell us

[grim hound]

if it were microoptimizations I wouldn't do it

[kind hatch]

Otherwise we can't give you a good solution.

[rough ibex]

You seem to like playing this game of "let's see how little info I can give and ask for also outrageously-dangerous solutions to these problems"

[hazy parrot]

That is exactly why it's important to explain what are u trying to do

[grim hound]

bro I don't need you blabbering if you won't help

[quiet ice]

Right now https://serverfault.com/a/636449 is the best option you have.
Running the entire server as root is very dangerous.
Anything else is impossible unless you somehow find a way to run iptables without superuser perms

[grim hound]

Firewall

[grim hound]

I know that running the server as root is dangerous

[rough ibex]

Putting others down and insulting people for asking for more info or giving possible solutions is not a good idea

[grim hound]

so I came to ask for that as well

[rough ibex]

You have been given the solution

(many)

and told the ramifications and side-effects

[kind hatch]

Running the server as root is as simple as logging in as root and running the start script. Or using sudo.

[quiet ice]

Yeah, hence you don't and instead only allow subcommands to be executed as root but for that you need to modify the sudoers file. There are no reasonable alternatives that I am aware of.

[grim hound]

I came to ask for the soultion

[rough ibex]

And you got it

[quiet ice]

I guess you could change the path of the iptables installation to not be within root? But requires even more setup on the user's side of things

[rough ibex]

still wouldn't work

it interfaces with the kernel

modifying iptables is a privileged operation

[quiet ice]

But what about the underlying database?

[rough ibex]

that's owned by root:root

I'm pretty sure

[quiet ice]

Yes, but what if we were to change that? If not - well then modifying sudoers it is. It is basically a one-liner anyways in terms of effort so there is little to complain

[hazy parrot]

Aren't rules stored in ram?

[quaint mantle]

log(n) space complexity

[kind hatch]

Still need sudo perms in this instance though.

[quiet ice]

At worst they are cached in ram

[quiet ice]

You need sudo somewhere along the line - no questions asked

You just have to ask yourself when you are going to run the sudo

[quaint mantle]

Reject incoming packets from ip using nms 🤔

[quiet ice]

that still incurs the overhead of netty

[hazy parrot]

Why would iptables need database?

[quiet ice]

Basically the idea is to move the firewall a layer down instead of keeping it on the application layer

[quiet ice]

Database as in a file where all rules are stored in

[rough ibex]

also not sure what "great exploits" there are

[quiet ice]

since you can't store them in volatile RAM

[grim hound]

not fast enough

I'm already doing that

[quiet ice]

But I mean iptables probably loads them into volatile RAM on startup so there is little point in doing so

[quaint mantle]

Bros can do rest api for iptables and run it on root. Users can do post/delete requests with that.

[kind hatch]

Sooo, we're dealing with packet spam of some sort then?

[quaint mantle]

Or socket

[quiet ice]

well analysed people.

[kind hatch]

Not much we can do other than speculate without being told what the actual issue is. :p

[grim hound]

ddos

[hazy parrot]

You are not gonna stop ddos with iptables

[rough ibex]

oh boy

iptables do not stop a DDOS

[quiet ice]

Yeah, but this was known from the get-go

[rough ibex]

You want DDOS protection, look at cloudflare

[grim hound]

it's still much faster than netty channel close

[quaint mantle]

Attacker have multiple ips

[grim hound]

I know

[quaint mantle]

One of them can be your client

[rough ibex]

?

[grim hound]

it's just enough

for it to be iptables

[quiet ice]

Well the lower the firewall is the more bandwidth you have available for the upper layers

[rough ibex]

Okay well you've been given the solution to use iptables

What more exactly are you looking for?

[quiet ice]

They found the option out themselves

Now I assume they want to automate that via a plugin. Hence, running iptables from a plugin. Which requires root perms. So you need to give it root perms

[grim hound]

but how can I use them?

how can I gain access to them?

[rough ibex]

You've been told....

[grim hound]

show me

[rough ibex]

I am not going to spoonfeed you

especially not after your hostility to help

[grim hound]

/\ bruh moment

[quiet ice]

That is the funny thing: There is no way.

[grim hound]

you were annoying

[quiet ice]

This is impossible within the constraints provided.

[grim hound]

hmmm

[quaint mantle]

Isnt it hosting's job?

[quiet ice]

Technically speaking, if you are running on a shared host it is not the responsibility of the server admin to avoid a DDoS

[quaint mantle]

Preventing ddos attacks

[rough ibex]

yes

[grim hound]

they allow all connections if they disguise themselves as minecraft traffic

[rotund ravine]

Don’t host a server

No ddos attacks

Otherwise look at mitigation

[wintry lynx]

big brain

[quaint mantle]

I mean

[rotund ravine]

There won’t be a “fix”

[quaint mantle]

Provider

[quiet ice]

Even on hetzner's could infra you don't have access to iptables as-is afaik

[shadow night]

Tipp of the day

[rotund ravine]

Cloudflares “fix” is by just throwing more resources at the issue and outresource the ddos attack

[grim hound]

well yes

[rough ibex]

Kind of hard to do anything else

[rotund ravine]

True

[quiet ice]

But uh, in the case of hetzner the firewall is not built into the VPS but rather somewhere else in the datacenter

I expect most other big datacenters to behave similarly

Anyways, does anyone know any annotation built into the JRE (Java 8) that has the TYPE_USE target and is public API?

I'd say no - but perhaps there is some random annotation that actually fits (as said, it can be literally anything, it just needs to compile)

[sage patio]

@tender shard doing what you said, i hope it doesn't take forever again, also i created this heapdump while the server was set to 12GB ram

[charred blaze]

so i want to code a plugin that toggles seeing glowing effect on players (for the command executor). Do i need to use protocollib or something?

[rough ibex]

for all players?

[charred blaze]

no, for command executor

[rough ibex]

https://www.spigotmc.org/threads/make-everybody-glow-to-one-player.465348/

google is your friend

[quiet ice]

?jd-s

[undone axle]

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

[sage patio]

its not working

i've a gen 3 ssd, why?

[quiet ice]

Nah, it's your RAM. Heapdumps are friggn massive and 8 gigs of memory is a lot less than needed unless you go with unconventional tools

Btw: You are killing your SSD right now as it is using your SSD as a replacement for the RAM.

[sage patio]

i know i'm damaging it

but i'm damaging my player count too with this memory leak on my survival server

mfnalex said 64gb swap may help you, but it doesn't

[lost matrix]

Swap is incredibly slow. You should benchmark and find the memory leak.

[sage patio]

benchmark?

[lost matrix]

*profile

[sage patio]

well i did, everything looks kinda normal except a huge PlayerMoveEvent and Location instances in memory

[lost matrix]

Spark has a pretty nice memory inspection tool
Would you mind sending what you found?

[sage patio]

sure. i'll send it in dms but before that i've to find it in activity log or creating another one

[sage patio]

also i have 32gb on my pc, it loads the heapdump easlity in visualvm but it can't calculate the gc roots and refrences

takes over a decade

[sage patio]

sent it in dms

[lost matrix]

Hm, what jvm params do you use?

[sage patio]

aikars

[lost matrix]

1GB of Location seems like a lot

[sage patio]

you can see it in the link i sent

[sage patio]

300mb PlayerMoveEvent? D:

[rough ibex]

woah 300mb

bro must be moving the whole universe

[shadow night]

The player moved and caused a reconstruction of the multiverse event

[sage patio]

lol

[lost matrix]

How many people have played during this snapshot?

[sage patio]

0 to 80 and now 40

80 at the same time, at all? i don't know

[lost matrix]

Same time. Im trying to estimate how many move events you could expect on average each second

[sage patio]

it goes higher if you don't restart the server

we've a daily autorestart

[slender elbow]

would love to know what plugin is doing that xD

[sage patio]

me too

[lost matrix]

Well in that case there is a horribly coded plugin which keeps hard references to the PlayerMoveEvent

Transitively increasing the Location amount

[shadow night]

Oh gosh

I GOTTA TRY THAT

[lost matrix]

22M WeakReferences are probably a result of the Locations holding references to their World as well

[shadow night]

oh gosh

[sage patio]

so the question is which fucking plugin

i guess i've to purchase a VDS with 256GB memory to figure out which one

[sage patio]

this is the only way to analyse a 12gb heapdump

[dry hazel]

no lol?

visualvm or eclipse mat can do it on a 16 gig system

[sage patio]

i've 32gb

[rough ibex]

that's enough then

[sage patio]

it loads the heapdump

[shadow night]

Is a heapdump just the whole ram dumped into a file?

[sage patio]

but it cannot compute the refrences or gc roots

[sage patio]

i don't know just did /spark heapdump

[quaint mantle]

Its object container

Quick question cause idk a clear answer

Is naming your artifact ID supposed to be all lowercase followed by dashes?

[quiet ice]

that'd be a coredump

[dry hazel]

spark's heapdump is hprof I think, that should work just fine in visualvm/eclipse mat

[sage patio]

i can share my screen in #690688600895127683

well, no idea, anyone?

[quaint mantle]

Can you tell class path of 300mb event listener?

[sage patio]

well i have no idea how this visualvm and stuff work, but someone said to just calculate gc roots which it takes a decade, is there another faster way to find out?

lemme load the heapdump into visualvm

[lost matrix]

Do you have a list of plugins? Maybe we can spot garbage right away.

[echo basalt]

my yourkit profiler license expired like a month ago

[lost matrix]

F

[sage patio]

i'll send it to you in dms

[lost matrix]

Ive seen the slimefun package which is already a gamble to put on your machine 🙂

[sage patio]

hmm

[sage patio]

what should i do exactly?

[echo basalt]

my favorite

[slender elbow]

click on the lil +

[echo basalt]

AureliumSkills, Slimefun

fun

[shadow night]

oh god

Looks simple

[echo basalt]

CraftMetaSkull is probably just slimefun having hard references to all its tile entities ok

[shadow night]

Is a hard reference one that causes memory leaks

[echo basalt]

No

[tender shard]

stupid git filter-repo --mailmap didnt change anything

[upper hazel]

how i can add prefix to nps in nms?

[echo basalt]

It's just a reference to a java object

[upper hazel]

what property i need

[slender elbow]

keep clicking lil +s until you find something interesting :^)

[sage patio]

well the second lil + on refrences lead me to wait untill 2077

[lost matrix]

Hm stream visualvm in voice?

[sage patio]

sure

[naive meadow]

Hi, i am getting this error when i try to execute query on mariadb server and idk what causes this: [23:13:31 ERROR] [aauth]: java.sql.SQLException: No connection available within the specified time (option 'connectTimeout': 30,000 ms)

[upper hazel]

when i was try create nps with nms minecraft say "big nick size"

[rough ibex]

what query are you running

[upper hazel]

how i can add prefix

to nps

[rough ibex]

NPS?

[upper hazel]

yes

"fake player"

not like vilager

[tender shard]

NPCs you mean

[upper hazel]

?

[rough ibex]

an NPC

[tender shard]

Its called NPC. Not nps

[upper hazel]

ok

Hello everyone, please help me, I can't add a placeholder with the privilege prefix "%luckperms_prefix%" to my plugin for the staff chat. Other placeholders also don't work. Help me how to add it to my plugin

[quaint mantle]

"Non Playable Character"

[upper hazel]

so how i can add prefix to NPS

with nms

[tender shard]

You have to use PlacerholderAPI.setPlaceholders(…)

[upper hazel]

NMS

[proud badge]

Hi I just cloned a repository but I cant seem to find, wheres the build button gone?

[quaint mantle]

Wait till sync

[naive meadow]

public boolean usernameExists(String userName) {
    String sql = "SELECT COUNT(*) FROM Accounts WHERE userName = ?";
    
    try (Connection conn = getConnection();

        stmt.setString(1, userName);
        ResultSet resultSet = stmt.executeQuery();
        
        resultSet.next();
        int count = resultSet.getInt(1);
        return count > 0;
    } catch (SQLException e) {
        e.printStackTrace();
        return false;
    }
}

[tender shard]

Is it still setting up? Gradle takes FOREVER when you first clone a large project

[proud badge]

Idk I just cloned it like 5 seconds ago

[rough ibex]

yeah wait

[tender shard]

Make a coffee, come back in 20 minutes

[proud badge]

Ok its here yay

[tender shard]

Its probably still not done kek

[proud badge]

does anyone know if CoreProtect needs shadowJar or not?

[tender shard]

If its in their build file, its probably needed

[mild cloak]

how can i make string text chaging color like white A next blue A

[quiet ice]

ChatColor.X?

[quaint mantle]

Impossible when alr sent

[proud badge]

its in the Shadow folder

[quiet ice]

then probably necessary

[rough ibex]

does he mean like text that changes

or just

WHITE + "A" + BLUE + "A"

[quiet ice]

<red>A<blue>B<yellow>C (beware: the actual syntax is something like \u00A7<code> instead of <red>, <blue>, etc. - <code> is some character from 0 to f and a few other letters. Look it up or use the ChatColor constants which have the \u00A7 "magic" character already defined)

[quaint mantle]

&fA&bA

[mild cloak]

yeah but like rainbow

[quiet ice]

ah, in that case use adventure if using paper, or bungee's chat components if on spigot

Or use some more user-friendly API such as minimessage

[mild cloak]

who you have one example

i using spigot btw

[quaint mantle]

Shadow adventue library(Platform bukkit) and minimessage

[quiet ice]

I always use paper when doing funny things with chat, so I don't know any examples from the top of my head - sorry.

[quaint mantle]

Ye bros gonna wrap player object every time when need to send a message

[tender shard]

Well minimessage works the same on spigot and paper, except that you need to create audiences manually

[tender shard]

That’s where kotlin extension functions are very useful for :3

fun Player.sendMessage(component: Component) …

[naive meadow]

is anyone knows how to fix and what causes this?

[kind hatch]

What's wrong with it?

[tender shard]

Are you using Hikari? Is your mysql connection limit set too low? Shared hoster or self hosted mysql?

[naive meadow]

[23:13:31 ERROR] [aauth]: java.sql.SQLException: No connection available within the specified time (option 'connectTimeout': 30,000 ms)

[quaint mantle]

Dont use mysql connector

Use jdbc class

[tribal quarry]

@sage patio eclipse memory analyzer has its own automated memory leak detection, I suggest you to use that instead of visualVM

[tender shard]

Btw you never close the ResultSet i think?

[sullen marlin]

lol

[slender elbow]

closing the statement closes the resultset

[naive meadow]

shared host but there is no problems with other things that connected to this mysql, my maxpoolsize is 8 and i am using mariadb jdbc

[tender shard]

Ah ok didn’t know

[slender elbow]

what does that getConnection() do exactly :hmm:

[naive meadow]

its datasource.getConnection()

[tender shard]

do you always get this, for every query you're trying to do with your plugin?

[naive meadow]

plugin have only one query right now

i am connecting with this

    private DataSource initMariaDbLDataSource() throws SQLException {
        try (MariaDbPoolDataSource dataSource = new MariaDbPoolDataSource()) {
            String url = "jdbc:mariadb://" + getAnnotatedConfig().getDbHostname() + ":" + getAnnotatedConfig().getDbPort() + "/" + getAnnotatedConfig().getDbDatabase() + "?user=" + getAnnotatedConfig().getDbUser() + "&password=" + getAnnotatedConfig().getDbPassword()+ "&maxPoolSize=8&allowPublicKeyRetrieval=true";

            dataSource.setUrl(url);
            testDataSource(dataSource);
            this.dataSource = dataSource; 
            return dataSource;
        } catch (SQLException e) {
            logger.error(e.toString());
            server.shutdown();
            throw e;
     }
    }

private DataSource dataSource; -> ```java

you must not create the datasource in a try with resources

[naive meadow]

i am using ```java
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;

[tender shard]

your datasource gets closed at the end

do not use try-with-resources for creating the datasource!

[naive meadow]

because i am using org.mariadb.jdbc-mariadb-java-client in this

[tender shard]

I told you what the issue is. get rid of the try-w-resources

private DataSource initMariaDbDataSource() throws SQLException {
    MariaDbPoolDataSource dataSource = new MariaDbPoolDataSource();
    try {
        String url = "jdbc:mariadb://" + getAnnotatedConfig().getDbHostname() + ":"  ... ;

        dataSource.setUrl(url);
        testDataSource(dataSource); 
        this.dataSource = dataSource;
        return dataSource;
    } catch (SQLException e) {
        // ...
    }
}```

[naive meadow]

ok.

[pallid oxide]

😍 Never knew this, gonna start kotlin soon at my school cant wait:D

[naive meadow]

now its working, thanks for help!

[tender shard]

np!

[tender shard]

what's also fancy is that you can compare object with > and < lol

        val myMcVersion = MinecraftVersion.current()
        val minimumSupportedVersion = MinecraftVersion(1,19,4)
        
        if(myMcVersion < minimumSupportedVersion){
            error("Fuck you")
        }

[young knoll]

Hey look it's C#

kek

[eternal night]

operator overwrite truely was the greatest invention known to mankind

[tender shard]

we get it, you hate kotlin and every single thing it adds

[pallid oxide]

:O

[eternal night]

I really don't hate everything

I adore the delegate feature

[rotund ravine]

1,19,4 looks cursed

[eternal night]

I'd love it if java pulled that

[tender shard]

doesnt lombok have a similar thing?

[slender elbow]

lombok should introduce operator overloading

[dry hazel]

just use manifold

[slender elbow]

true ..

[rotund ravine]

Manifold dors **^

[young knoll]

I wouldn’t mind it ig

As long as people don’t be stupid with it

Player / Player

[tender shard]

does anyone know how to fix this? this has been bothering me for days (since I updated gradle to 8.6). idk why IJ doesn't understand that there's a setter

[dry hazel]

it returns T

so it's not really a property-like accessor

[young knoll]

Does Kotlin only recognize setters that return void?

[dry hazel]

yes

[young knoll]

Rip

[tender shard]

but why does it compile fine then?

it's only IJ complaining

when going back to gradle 8.5, it also returns T and IJ does NOT complain

[rotund ravine]

IJ

And gradle

Are not good friends

[hasty prawn]

gradle doesnt have friends

[tender shard]

I just wonder why it complains about it in gradle 8.6 but not in 8.5 when the method has not changed at all

and as said, it works fine, it's only IJ not understanding it 🥲

[tender shard]

at least it's not make

[hasty prawn]

touche

[kind hatch]

Why does abstraction have to be so damn difficult?

[rotund ravine]

It’s not

[tender shard]

https://tenor.com/view/boom-roasted-the-office-michael-scott-gif-9210948

[kind hatch]

I guess I'm just bad at it then. 😭

[flint coyote]

We've all been there. You'll grow with experience

[glacial narwhal]

?paste

[undone axle]

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

[glacial narwhal]

Why does this not change the death message ? https://paste.md-5.net/ipaxapaziy.java

[tender shard]

did you register the listener?

[glacial narwhal]

Yes

[glacial narwhal]

It give me this error: https://paste.md-5.net/uhehamahiz.sql

[tender shard]

then probably RoleUtils.getPlayerRole(deathPlayer) returns null

[glacial narwhal]

I'll check

[glacial narwhal]

Yeah it returned null, now it works thanks!

[tender shard]

np

btw if you use newer java versions, the error tells you what exactly is null

in java 14 and newer it looks like this

Cannot invoke "Role.getColor()" because the return value of "RoleUtils.getRole(player)" is null

[glacial narwhal]

I'm using java 8

so i don't have it

[pallid oxide]

time to upgrage:)

u can also do things like

if (object instanceof Player p) {
p.sendmessage()
}
instead of 
if (object instanceof Player ) {
Player p = (Player) obj
p.sendmessage()
}

and lots lots of cool stuff in newer versions

[sand spire]

Hey, I'm trying to make it so I can change the title of the GUI from outside, but for some reason no information can be passed into the createInventory method.
https://pastes.dev/h1VdnPGytc
Does anyone know what is blocking this information and what I can do to solve this issue?

[tender shard]

once you open the inventory to someone, you got an InventoryView. And there you can update the title as often as you want https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/inventory/InventoryView.html#setTitle(java.lang.String)

[sand spire]

Like this?

InventoryView inventoryView = (InventoryView) getInventory();
       inventoryView.setTitle(title);```

[slender elbow]

an Inventory is not an InventoryView

an InventoryView is available to you when the player opens the inventory (or is made open via Player.openInventory)

[tender shard]

no

player.openInventory(yourInv) returns an InventoryView

[glass flicker]

no like this public abstract class InventoryGUI implements InventoryHandler {

private final Inventory inventory;
private final Map<Integer, InventoryButton> buttonMap = new HashMap<>();

public InventoryGUI(String title) {
    this.inventory = this.createInventory(title);
}

public Inventory getInventory() {
    return this.inventory;
}

// 5 methods irrelevant to the problem

protected abstract Inventory createInventory(String title);

}

public class BuyItemGUI extends InventoryGUI {

public BuyItemGUI(String title) {
    super(title);
}

@Override
protected Inventory createInventory(String title) {
    System.out.println(title);
    return Bukkit.createInventory(null, 3 * 9, title);
}

}

when you next create an instince of buyitem gui example bud need further assistance lmk

[glass flicker]

BuyItemGUI buyItemGUI = new BuyItemGUI("New Title");
Inventory inventory = buyItemGUI.getInventory();
// Now the inventory will have the title "New Title"

[sand spire]

Thanks yall, I think this should work "player.getOpenInventory().setTitle(title);" and I will also try your solution jacob

[glass flicker]

no problems have a blast with it might need to change a lil bit but if you do shoot a question here and will pick it up if you do

[wintry lynx]

Anyone know datapack stuff?

If so

Does setting terrain adaptation in a structure to anything but 'none' just break it or am I somehow failing to spell

[young knoll]

Should work fine

As long as you have it set right

[spare mason]

How could I use block displays to draw a vector?

[tender shard]

A vector is just a line in 3D space

What do you want to do exactly

[eternal night]

every mathematician shivering

[ivory sleet]

weeeeell, it has a direction also

[tender shard]

Is line the English word for Gerade?

[eternal night]

I mean, it isn't a gerade either

[tender shard]

I thought a line has a start and end point

[eternal night]

which a vector doesn't

tEchNicAlly

[tender shard]

Yeah thats what i meant

Its a line between start and end point

[ivory sleet]

well u have free and bounded vectors

as different mathematical object types

[eternal night]

🤓

[mint nova]

is there any event for clicking item (like not inventory but hotbar you know) i cant find

[remote swallow]

any githuh workflow nerds know how to improve speeds, mainly with like caching dependencies

[tender shard]

I assumed they meant a bukkit vector which is just 3 doubles or floats

[tender shard]

Yes

[wintry lynx]

It is. It just says java.lang.IllegalStateException: Failed to parse revamp:worldgen/structure/desert_pyramid.json from pack file/Structure_Revamp

[ivory sleet]

[tender shard]

https://github.com/SpigotBasics/basics/tree/main/.github/workflows

That already caches stuff reasonably

Default settings haha

[remote swallow]

well it has to download and do whatever to every single dep each time i run it instead of having a local m2 with them in or smth

[tender shard]

You can set „cache: gradle“

[remote swallow]

on setup java?

[tender shard]

On the same level where you do runs-on iirc - IJ has autocomplete for it

[remote swallow]

appears it is on setup java

[tender shard]

Oh ok might be

Oh yeah it should be in the „with“ part of setup java i think

you can also manually add directories to cache, sth like this

    - name: Cache Gradle packages
      uses: actions/cache@v3
      with:
        path: |
          ~/.gradle/caches
          ~/.gradle/wrapper
        key: ${{ runner.os }}-gradle-${{ hashFiles('**/*.gradle*', '**/gradle-wrapper.properties') }}
        restore-keys: |
          ${{ runner.os }}-gradle-

not sure if this is correct

[remote swallow]

when testing in act it just says this

[tender shard]

hm mine says "cache saved successfully"

I only used this

    - name: Set up JDK 17
      uses: actions/setup-java@v4
      with:
        java-version: '17'
        distribution: 'temurin'
        cache: "gradle" # <- this

the rest is exactly like the repo I sent above

[remote swallow]

mines this

ill try it without m atrix

same thing, ig ill try it on actual github

[tender shard]

Huh where did you try it

[remote swallow]

act locally

https://github.com/nektos/act

seems like it caches as expected on workflows

[young knoll]

What kind of wizardry

Hi the FileConfiguration save methods remove all " " from my config.

before:

item-name: "TEST"
item-lore: "sdfgsdgf"

after

item-name: TEST
item-lore: sdfgsdgf

is there a way to prevent save methods to remove " ?

[remote swallow]

no

[young knoll]

You’d have to use a custom implementation of SnakeYaml

The spigot one is set to remove unnecessary quotes

[rough ibex]

I'm not sure why you want to force quotes

they aren't needed unlike JSON or such.

[lost matrix]

For some entries they are necessary

[rough ibex]

true

but for TEST and sdfgsdgf they aren't

and .save shouldn't be dangerously removing quotes.

[lost matrix]

yep

[wintry lynx]

So i figured it out... They just really like to hide the error in the log lol

[young knoll]

How big is this thing

O_O

[wintry lynx]

Large

lol

Its like 80

so it shoukd work fine

I got it to work tho

[wet breach]

is it doing it for everything, or just things that are normal strings?

Could someone familiar with populating chest inventories help me out?
I'm intercepting a BlockPlaceEvent to populate a placed chest with an ItemStack[].
I want to use the Container.getInventory.setContents(ItemStack[]); but it's not working.
If I set up a for loop and use the Container.getInventory.setContents(int,ItemStack); it doesn't work either.
Only Container.getInventory.addItem(ItemStack) works, but then I lose the original placement of the items in the ItemStack[].

I have confirmed that my ItemStack[] is populated, it's just not filling the chest with the two functions I'd like to use.

Going to bed now, but if anyone has any advice please @ ping me
Thanks all

[tender shard]

[lost matrix]

[topaz kestrel]

how call a overridden method from children classes in parent class?

[pallid oxide]

u mean super.method()?

or u mean if u have
animal and dog which extends animal and dog overrides makesound()
and in animal u want to call that makesound of the dog?

[pallid oxide]

^

[topaz kestrel]

yes

but not "dog" specifically

it's like

[tall dragon]

that is not possible as far as i know

cuz how does animal know which one to use?

there might be 10 classed overriding it

i also cannot think of a use case where you would need this. maybe explain what you want to do?

[topaz kestrel]

I don't know how to explain this. can you join voice call and see my screen share?

[tall dragon]

sure

[pallid oxide]

yes u can do that

add me to call aswell

[hazy parrot]

How can u call child method from parent class?

Im not aware of it lol

[sullen canyon]

If I want to precreate config.yml I just add it to the same directory as plugin.yml and then in the onEnable method I do saveDafaultConfig()

But what if I want to have other configs premade? Is it possible? Or is it only for the config.yml? Because I do not really want to use addDefault method

[hazy parrot]

There is saveResource method inside of JavaPlugin class

You can use it to "extract" from resources to plugin folder

[sullen canyon]

didn't know about this

thanks

[rough drift]

@sullen canyon you can use saveDefaultConfig();

calls saveResource on the config.yml

[sullen canyon]

although it wouldn't work for others .yml files?
If I want to have config.yml and config2.yml it would load only config.yml Ig

Right?

[rough drift]

yep

just saying in case you only had one

[pallid oxide]

lets say u have abstract class Animals with abstract method makeSound();
and with method
public void eat() {
makeSound();
}

And then you have
Dog extends Animal {
and implement here makeSound method
}

That will call the childs makesound in animal

[hazy parrot]

🤦‍♂️

Guys can you help me please? Using nms for respawning player in order to update his skin, but it doesn't work properly. It takes 30 seconds to load and loads only first layer of skin. ( if I respawn self(player) manually by nether portal, it loads without any problems)

My respawnPacket code:

CommonPlayerSpawnInfo spawnInfo = new CommonPlayerSpawnInfo(
                nmsLevel.dimensionTypeId(),                                // dimensionType
                nmsLevel.dimension(),                                    // dimension
                nmsLevel.getSeed(),                                        // Seed
                serverPlayer.gameMode.getGameModeForPlayer(),            // playerGameType
                serverPlayer.gameMode.getPreviousGameModeForPlayer(),    // previousPlayerGameType
                nmsLevel.isDebug(),                                        // isDebug
                nmsLevel.isFlat(),                                        // isFlat
                serverPlayer.getLastDeathLocation(),                    // lastDeathLocation
                (byte) 1                                                // keepAllPlayerData
        );

        ClientboundRespawnPacket respawnPacket = new ClientboundRespawnPacket(spawnInfo, (byte) 0);```

What

I would just wrap it in CompletableFuture if ur asking that

why dont you respawn the player using the respawnPlayer() method

oh nvm that only works if they're dead

@eternal oxide can you check it out please

[tame wolf]

Why did you ping them

[grizzled cedar]

I'm sorry if I can't. But Elgar is an author of the code, so I supposed that he knows the issue

[tame wolf]

An author of your code?

[grizzled cedar]

No, the part I have the problem with

[eternal oxide]

There is nothign in teh code you posted which would take 30 seconds

You don;t send the entity data there so of course you have a single layer skin

[grizzled cedar]

You mean send entity data via respawn packet?

Or how can I do that

[eternal oxide]

no

?paste

[undone axle]

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

[eternal oxide]

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

you need all those packets to correctly change a skin

[grizzled cedar]

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

[eternal oxide]

What exactly is taking 30 seconds?

[grizzled cedar]

Player respawn

[eternal oxide]

uh

You must have somethign messing with it then

Its just a packet

[grizzled cedar]

All other players see skin change immediately

[eternal oxide]

oh you just mean for yourself it takes 30 seconds to see the skin change?

[grizzled cedar]

yeah

and only one who changes skin can see only one layer

[eternal oxide]

what spigot version?

[grizzled cedar]

1.20.4

[eternal oxide]

I doubt that code even runs on 1.20

oh yes it will. silly me 🙂

I haven't tested it since 1.18

only that it builds and runs

It worked perfectly on 1.18 but since I have not looked, other than protocol changes

[grizzled cedar]

but it does work

it changes skin perfectly, only can't refresh it for player who changes it

with dimension change it refreshes and 2nd layer shows up, so it's problem with respawning

But I have no idea how to fix that

[mental moon]

Figured it out.
There's a distiction between .getInventory and .getSnapshotInventory that I didn't understand.
If I don't get the Snapshot Inventory and force a tilestate update it reverts to the previous state (???)
#7 on https://www.spigotmc.org/threads/set-chest-item.377989/#post-3437227
was the solution

[young knoll]

Yeah

getInventory is the live inventory

[fluid river]

imagine ```csharp
private Dictionary<Type, List<object>> eventMatrix = new();

public void AddEventListener<T>(EventListener<T> listener) where T : AbstractEvent
{
var type = typeof(T);
if (!eventMatrix.ContainsKey(type)) eventMatrix[type] = new List<object>();
eventMatrix[type].Add(listener);
}

public void RouteEvent<T> (T eventData) where T : AbstractEvent
{
var type = eventData.GetType();
foreach (var listener in eventMatrix[type])
{
((EventListener<T>)listener).OnEvent(eventData);
}
if (eventData is ICancellable c)
{
if (c.isCancelled())
{
c.CancelAction();
return;
}
}
eventData.Action();
}```

and the best part

public void RemoveEventListener<T>(EventListener<T> listener) where T : AbstractEvent
{
    var type = typeof(T);
    if (!eventMatrix.ContainsKey(type))
    {
        Logger.GetLogger().Log("EventSystemWarning: " + (listener.GetProvider() is GameListenerProvider ? "Game" : "Mod " + listener.GetProvider().GetName()) + " tried to remove listener to non-existing event");
        return;
    }
    eventMatrix[type].Remove(listener);
}```

Since i don't really know how JavaPlugin.getProvidingPlugin(Class clazz) works and how to replicate it in c#, i stored provider as a field of every listener

[echo basalt]

I need to rewrite mine a bit but generally just uh

split things up a lot

[icy beacon]

How do yall backup your vps

[radiant aspen]

greetings people

any advice on how to create worlds in code when your server is up

Got this code atm

                WorldCreator worldCreator = new WorldCreator(worldName)
                        .generator(IridiumSkyblock.getInstance().getDefaultWorldGenerator(world.getName(), null))
                        .environment(world.getEnvironment())
                        .seed(world.getSeed());

                worldCreator.createWorld();

but im wondering if this will cause lagg issues, since its creating a whole new world in a single tick

is there a way to create this async, or anything?

[echo basalt]

Async generation? good luck

[eternal oxide]

all world creation will cause lag. No you can;t do it async

[echo basalt]

^

[eternal oxide]

create it as teh server loads, before you need it

[echo basalt]

If you need multiple worlds you should like.. delay their generation n stuff

[radiant aspen]

Any way to spread it out over multiple ticks though?

[eternal oxide]

no

[echo basalt]

Nope

[shadow night]

why is async generation not possible

[echo basalt]

because minecraft is gimmicky

[radiant aspen]

probabbly same reason you cant set block states async

[shadow night]

asscraft

[radiant aspen]

idk mc is weird

[echo basalt]

For minigames and skyblock-like plugins I just use slimeworldmanager

but then again these are not public plugins

[radiant aspen]

nah

slime world manager sucks

[quaint mantle]

Ex javascript developer:

[shadow night]

Thread safe minecraft when

[eternal oxide]

If I need multiple worlds I create a template, then file copy and load as needed

as you can copy files async

[shadow night]

Kopieren of files

[radiant aspen]

basically we are trying to find a way to re-generate terrain in a minecraft world. the sollution we came up with is to create a new world with the same seed, and copy the blocks over

which is supper hacky, and from what I can tell will probabbly cause alot of lagg issues with creating the world

but idk any other methods which are less shit

[eternal oxide]

why not just load a set number of chunks over a few ticks?

[radiant aspen]

wdym?

[eternal oxide]

allow the natural world gen to create teh chunks

oh you want to REgenerate terrain

[radiant aspen]

yeah mb

[narrow ledge]

regenerate the terrain while using a custom generator

[eternal oxide]

in that case backup each chunk load if it's a new chunk

[radiant aspen]

its my skyblock plugin, we are looking into adding ocean world types aswell as void types

but then deleting/regenerating the islands is causing issues since we dont know how to regenerate the origional ocean terrain

[radiant aspen]

yeah, thats true I guess, but then we need to find a method to save the chunks

tbh, I guess we could just save the block states in json, serialize it to like base64 and shove that base64 in some db somewhere

[narrow ledge]

i did look into just replicating the math for that portion of the world, and it does work, but we're also using the decorate method flag thingymahbob and you cant really replicate that with just math

[echo basalt]

mm not a good idea

[radiant aspen]

well none of these are good ideas

its just which one is the least worst

[echo basalt]

If you are going to be storing chunk data you'd want to actually encode it in a nice way

not just toss it in a base64

[tender shard]

proxmox

[echo basalt]

Remember, each chunk section has 4096 blocks

[radiant aspen]

I mean it wouldnt be exact chunks

[narrow ledge]

thats the worst part 😔

[radiant aspen]

we would probabbly just get the two corners of an island, get the materials inside each island, and just create like a list<BlockState> or some object containing Location and Material

[echo basalt]

Even then you want to compress that further

[radiant aspen]

since there shouldnt really be anything too fancy that we have to deal with specific orientation or any other data

[echo basalt]

Use some sort of pallette

[valid basin]

how to override a bungee command with spigot command? I use /hub on bungee but I'd like to use different /hub on certain spigot server. It's possible?

or do I need to use commandpreprocess event?

[chrome beacon]

The Bungeecord will always take priority

You'd have to make a Bungeecord plugin to get around that

[valid basin]

what if I use commandpreprocess event?

bungee will still take priority?

[chrome beacon]

yes

[tardy delta]

what

[remote swallow]

iirc its gradle 8.2.2 that has 21 support

[tardy delta]

ah right

[alpine urchin]

yea

[tardy delta]

how do i even update gradle from within intellij?

[remote swallow]

easiest way is change the url in gradle/wrapper then the properties file

[violet delta]

1.8 i think ;o

what should my POM file look like for latest version spigot plugins? how do i change the default pom file, i keep having to manually change it to 1.8 from 1.7

[tender shard]

depends on how it currently looks. you can set the java version directly in the maven-compiler-plugin, or through properties

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-compiler-plugin</artifactId>
  <version>3.8.1</version>

in properties, change maven.compiler.target and maven.compiler.source to 17

[violet delta]

where is that?

[tender shard]

in your pom?

[violet delta]

im trying to change it before its generated so i dont have to manually change the pom file every time after creating new project

[tender shard]

?

[violet delta]

idk how to update my mavens default pom

besides manually editing pom

[tender shard]

you can write your own archetype

[violet delta]

ohhhh crap

[tender shard]

here's an example of how it works https://github.com/mfnalex/spigot-plugin-archetype

it's much easier to just use IJ's new project wizard

just do New Project -> Maven and you can choose the JDK version

[violet delta]

your spigot archtype seems like just what i needed lol

what about the spigot API version my my POM? thats correct for latest spigot delelopment? https://paste.md-5.net/olalinemow.xml

well that's for 1.15.1

latest is obv 1.20.4 :p

Is this will be working?

        int totalBlocks = 0;
        for (Statistic statistic : Statistic.values()) {
            if (statistic.getType().equals(Statistic.Type.BREAK_BLOCK)) {
                totalBlocks += Bukkit.getServer().getOfflinePlayers().stream()
                        .mapToInt(player -> player.getStatistic(statistic))
                        .sum();
            }
        }
        System.out.println("Total block count: " + totalBlocks);
    }``` I want to count all mined blocks

[tender shard]

        List<Material> blocks = Arrays.stream(Material.values())
                .filter(Material::isBlock)
                .collect(Collectors.toList());

        int allMinedBlocks = blocks.stream()
                .mapToInt(block -> player.getStatistic(Statistic.MINE_BLOCK, block))
                .sum();

sth like this should work. You wanna cache the list of blocks though. Also maybe you can also just directl use Statistic.MINE_BLOCK, i don't know

[ivory depot]

im making statistic plugin, and i dont want to count all block break events, because this is made ingame, so i want to summary all types of blocks, thank you i will check it

throws error: Must supply additional parameter for this statistic

[tender shard]

then you have to do it for each block specifically, as I said

[ivory depot]

okay, thanks

temp = offlinePlayer.getStatistic(Statistic.MINE_BLOCK, Material.COBBLESTONE);``` in this case is the same error

so idk what is wrong with this

[tender shard]

show the whole error message

[ivory depot]

https://mclo.gs/4Sj4VSE

[tender shard]

what's BlockCountUpdateEvent line 26?

Hey,
does anyone know how I can create a explosion which is bigger than a tnt explosion and puts down fire, but where I can still change the block list so it only destroys certain block types in paper 1.8.8?
Vecause when using createExplosion() the EntityExplodeEvent doesn't get triggered.

[torpid blaze]

I just found out there is a BlockExplodeEvent. Before then Typing ExplodeEvent it didn't show up

[green prism]

Hello,

I'm currently working on implementing deserialization from a Bson Document to ConfigurationSerializable. The entityClass is properly configured, and when I print the map entry, it contains the same entries as those for the Card POJO. However, despite this, the #deserializeObject method still returns null.

    @Override // todo: add this in the service interface of mysql
    public ConfigurationSerializable fromDocument(Document document) {

        // Puts all the entries of the document into a new map
        Map<String, Object> map = new HashMap<>(document);
        map.remove("id"); // Remove the id from the map, otherwise, entityClass which doesn't contain id will throw an exception (?)

        for(Map.Entry<String, Object> entry : map.entrySet()) {
            System.out.println(entry.getKey() + " B: " + entry.getValue());
        }

        return ConfigurationSerialization.deserializeObject(map, this.entityClass);
    }

Printed result from the for-cycle:

test B: 6

Where the entityClass gets set

this.cardRepository.setType(Card.class); // This is from the Main class 

    @Override
    public void setType(Class<T> type) {
        this.type = type;
        this.service.setClass(type); // entityType == type
    }

Card.class POJO:

@Data
@Builder
public class Card implements ConfigurationSerializable {

    // Card type variables

    @BsonProperty("test") // Mongodb impl related
    private int test;

    @BsonCreator
    public Card(@BsonProperty("test") int test) {
        this.test = test;
    }

    @Override
    public Map<String, Object> serialize() {
        return Map.of("test", test);
    }


}

No worries, it's not that big 🤣

[carmine mica]

You mean because of the version bump?

[spare crypt]

Last night, DamageSource stuff got merged, but there was no version bump to go with it?

[carmine mica]

The Java version the api is compiled with was bumped is what I meant. What other “breaking” change are you talking about?

[remote swallow]

there never is

rerun buildtools for the server jar + the full spigot dep if you need it or refresh maven

[spare crypt]

Ah. Yeah. The Java version bump is another aspect of that for sure. It's breaking because I have a plugin that extends EntityDamageEvent. With the new DamageSource added to the constructor, the plugin can't run on the new build until I make adjustments, but then I lose backwards compatibility for any version before this last build.

[carmine mica]

Event constructors are not API

So changing them isn’t considered a breaking change

That is made clear in the javadocs

Extending/Implementing API types that aren’t explicitly made for extending/implementing also isn’t considered API, so any changes regarding that isn’t “breaking” either

[spare crypt]

One could argue that if it wasn't intended to be extended, it should have been made final then. Either way, it puts an interesting kink in things

[sullen marlin]

https://hub.spigotmc.org/javadocs/spigot/index.html?overview-summary.html

[spare crypt]

Thank you MD

[sullen marlin]

What are you calling the event for anyway, is there not an API method that does what you want?

[slender elbow]

under that premise none of the API would exist as it is given that it's all interfaces you can technically implement, but you shouldn't

[spare crypt]

I'm utilizing the event (specifically extending EntityDamageByEntityEvent) as a "fake" event to see if any other plugins cancel the event. It's kind of a hacked way to determine if entities/players are damageable by the player before doing other things to the target entity

[sullen marlin]

Maybe Damageable.damage should return a boolean

[rotund ravine]

Let’s hope the enduser isn’t using smth like spartan or another event based anticheat

[spare crypt]

That was my other thought

[spare crypt]

Does that even listen to canceled events? As soon as the check comes back, if it wasn't externally canceled, I cancel it anyway

[sullen marlin]

Open a feature request, it'd be pretty easy to change the new method at least

Hey md, would you be able to lend a hand with my issue?

[rotund ravine]

Not chest and not doublechestie

[torpid blaze]

and I don't have another InventoryOpenEvent in my project

[sullen marlin]

Craft chest implements chest. make sure that's the code that's running

[torpid blaze]

it is

I already executed it 20 times

[rotund ravine]

Does the event get cancelled

[torpid blaze]

yes

[rotund ravine]

Then it works fine

[sullen marlin]

I have no idea about bson, but if you're serialising complex types you need to recursively handle configurationserialiszblr

[torpid blaze]

I added sout s

[torpid blaze]

when going into the Chest, it does not implement CraftChest:

package org.bukkit.block;

public interface Chest extends org.bukkit.block.BlockState, org.bukkit.block.ContainerBlock {
    org.bukkit.inventory.Inventory getBlockInventory();
}

[green prism]

Well... The issue is not really about Bson:

    @Override // todo: add this in the service interface of mysql
    public ConfigurationSerializable fromDocument(Document document) {

        // Puts all the entries of the document into a new map
        Map<String, Object> map = new HashMap<>(document);
        map.remove("id"); // Remove the id from the map, otherwise, entityClass which doesn't contain id will throw an exception

        for(Map.Entry<String, Object> entry : map.entrySet()) {
            System.out.println(entry.getKey() + " B: " + entry.getValue());
        }

        return ConfigurationSerialization.deserializeObject(map, this.entityClass);
    }

[remote swallow]

CraftChest implements Chest

not Chest implements CraftChest

[green prism]

it's just a simple map, correctly converted from Bson Document

[torpid blaze]

oh

lost

sorry

[late sonnet]

pkl?

[ivory sleet]

Think they mean those programming language thingies that are specifically made for configuration

But like, it would be a real hassle to remove yaml all of a sudden

[minor junco]

I don't think it would be that great for most plugins (if we talk Minecraft) to begin with

[ivory sleet]

But yeah pkl is cool

[minor junco]

What might be a great idea is to use validation when loading the configuration and generating a schema off of it, kinda like Zod (typescript world)

If it's like really complex, maybe

But I don't think it's that great of an idea to give a pkl config to an end user who might not be familiar with this

[inner mulch]

Lets say I have a manager, which has a method that is supposed to add something to a list. Is it okay to also have it send a message to the player (feedback to the player) , or should i do that in the implementation (when i use the manager's method). Im asking this because Im not sure if this breaks the principle of a single responsibility?

[ivory sleet]

that’s hard, manager is a really high level abstraction pattern

Usually you’ll see managers being some sort of composition of other patterns

[inner mulch]

what does high or low level mean?

i heard this a lot

[minor junco]

Again, I think it's the best idea for the end user and developer / zero error tolerance of a stable plugin to have a validation, ensuring constraints set on a configuration rather than defining those constraints publicly and putting them right into the configuration itself. Idk

[inner mulch]

and btw since when are message not highlighted that are responses to sent messages by the user (discord)?

[ivory sleet]

Its a notion we talk about, it doesn’t really exist in the language itself, but you know how like a system usually has a bunch of classes, some classes will never call other classes, some classes do specific things, other classes become generalizations, after such analysis, its almost always possible to derive some tree based structure of how classes depend on each other

high level abstraction usually refers to the classes on top of everything else, those that could be api to other modules/projects, and low level abstraction refers to more concrete and implementation specific classes

Ofc its all relative, I mean if you code a sql connection pool project, that’s gonna define one abstraction hierarchy, whereas coding an entire minecraft server will have its own abstraction hierarchy

but the point of this is that you to some extent are able to isolate, moduralize and define clear types of relationships between components

[inner mulch]

okay, so in terms of my manager, it basically just adding or removing stuff from a list, and those methods are mainly called in commands, therefore im not sure whether i should send user feedback in the command itselfs or just implement that into the manager's methods. But that would break the principle of a single responsibility, right?

[ivory sleet]

Single responsibility principle by definition says that a class must only be held one major reason for it to change

for instance, you wouldn’t wanna change the CommandParser class if you needed to migrate the database module

if the functionality of command parsing needs to be changed, improved or altered, then that’s the only reason you’d ideally wanna reason about in order to change CommandParser

This principle is vague, and there is no clear definition, but usually its good to only have one big reason why your command class should change

Its hard also, if you overdo it, there might be other design issues you face, such as defining one class per function, which also isn’t what you want (presumably in most cases)

[inner mulch]

okay, thank you :)

[ivory sleet]

from what I know usually people have some sort of command manager, or some class that stores all the data of all commands, then you have one class that is responsible for the querying of commands (like a command map), one class that does the parsing, one class that does the dispatching (which can be good if you want to execute a command async etc)

i just made up this on the spot, but reasoning like this can get u relatively far I reckon ^^

[shadow night]

I'm making a little whitelist plugin (just a private thing so I can customize it and stuff) and is there some way to identify who's sending a ping packet?

People just don't know how

[zenith bobcat]

[zenith bobcat]

Would you do know how?

[chrome beacon]

Yeah

[zenith bobcat]

Then now my question is why use Base64 enconding?

[ivory sleet]

Olivo knows everything Julix ;)

[chrome beacon]

So it can be stored as a String

[zenith bobcat]

thats good 😉

[shadow night]

Can't you convert between bytes and chars

[zenith bobcat]

you can store a byte Array also in a String

ok i am not realy sure if you can do that but it would make sence

[shadow night]

Isn't it also as simple as new String(byte[])

[quaint mantle]

i was away to show you the simplest and most efficient way i found to do it but ive deleted my source code :D

yeah i think so too

You can but again many people don't know that

oh shit that would be great

dk if thats of any help

but thats the way i did it

and it works perfectly

[shadow night]

So, you are saying people are mostly dumbf'cks

[quaint mantle]

i dont. chatgpt questions most of my code though :)

[ivory sleet]

Some are just… ignorant

[zenith bobcat]

thanks for that code

[quaint mantle]

i believe i made you a new profile picture a while back, didn't I? using chatgpt

[shadow night]

No idea

[shadow night]

Isn't that a nice way of saying dumbf'ck

[quaint mantle]

omg i did

[shadow night]

Can you send it two images? So it has both my skin and my pfp

[quaint mantle]

uhm i stopped paying for it because i ran out of money lol

[shadow night]

Lol

Well, time passes too fast

[quaint mantle]

yehp

especially when you play minecraft all day everyday, definitly doesn't help

[shadow night]

we a bit off topic now aren't we lol

[quaint mantle]

well technically we are on the topic of your profile picture, we had this discussion last time aswell.

[shadow night]

Well, this is help-dev

[quaint mantle]

but yes, in regards to the channels purpose, it could be coonsidered off topic

anyways. i need help coding a super advanced AI model and help puting it in to minecraft. any suggestions

[tall dragon]

ask chatgpt 😂

[sage patio]

"how i can create the chatgpt 2"

[proud badge]

Which one is faster?

[eternal oxide]

should be the same a single op

[ivory sleet]

yea it should be negligible, the difference, if any

[tardy delta]

look at the jit compilation of if_icmpgt and if_icmpgte in the jvm if it interests you 😂

[kindred sentinel]

How to get the country of the player's ip?

[tardy delta]

you use an api for that

[ivory sleet]

🤨

[kindred sentinel]

hm, do you know any api which could be useful for this?

[tardy delta]

first thing i see is country.is

[kindred sentinel]

ty

[sudden raft]

actually in that case the compiler would use if_icmple and if_icmplt

🤓

[tardy delta]

mye could be, i always take the wrong comparison in asm

you would think the compiler would do a gt or gte to then avoid a jump but no

[kindred sentinel]

Wanted to add unirest-java dependency, but got this error, do you know what could make this?

[tardy delta]

thats a vulnerability warning

update it if theres a newer version or ignore it

[kindred sentinel]

ok

[violet delta]

?paste

[undone axle]

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

[kindred sentinel]

Is there any way to disconnect player while he joining the server?

Or only player.kickPlayer?

[violet delta]

what is the problem https://paste.md-5.net/yipupepaju.md i have the latest spigot jar on my server and set the API version to <version>1.20.4-R0.1-SNAPSHOT</version> in my POM

"Unsupported API version 1.20.4"

[remote swallow]

use 1.20 as api version

[young knoll]

In the AsyncPreLoginEvent there is event.disallow

[kindred sentinel]

is event.setResult(PlayerLoginEvent.Result.KICK_OTHER); the same?

in LoginEvent

[young knoll]

Probably

Just later and not async

[kindred sentinel]

I used it cause I wanna get the player's ip first

[young knoll]

That’s available in the async one

[kindred sentinel]

oh, ok then I'll use the async one

thanks

[frail sluice]

How can I detach a villager from its bed and workstation?
Also, is it possible to give certain villagers a different texture (using a resource pack, of course)

[violet delta]

i changed it to <version>1.20-R0.1-SNAPSHOT</version> its still giving same error

[remote swallow]

change it in plugin.yml

[frail sluice]

setProfession doesn't free the bed and workstation from my testing

Alright thanks

[undone axle]

https://hub.spigotmc.org/stash/

[frail sluice]

That's NMS right?

[eternal oxide]

no

Its Bukkit implementation

[tender shard]

has anyone ever seen such a tiny /give command?

[frail sluice]

I see

[rotund ravine]

Not using the return value of addItem reee

[tender shard]

ew

[frail sluice]

@eternal oxide is it possible to access net.minecraft.world.entity.npc.EntityVillager

[echo basalt]

meanwhile I found a flaw with advancedslimepaper today
