[lost matrix]

Ah yes. Mojang fkery.

[hushed spindle]

wdym dont know how to get the name

its an enum isnt it

[lost matrix]

    net.minecraft.world.entity.EntityType<?> nmsType = net.minecraft.world.entity.EntityType.BEE;
    ResourceLocation resourceLocation = net.minecraft.world.entity.EntityType.getKey(nmsType);
    String path = resourceLocation.getPath();
    EntityType bukkitType = EntityType.valueOf(path.toUpperCase());

[cinder abyss]

oh thanks!!

it's harder than "just getting the name" x)

[lost matrix]

*If the enum names are matched

But there is probably a better way. I just eyeballed this from the src code.

[cinder abyss]

if it doesn't match, I think it won't be the end of the world

maybe but I think no

starting getting big 💀

Caching is key or your reflections will be very slow

[cinder abyss]

any tutorial to caching?

[hushed spindle]

caching literally just means to store your method params and their outputs in a map or something so its in memory

and to return that cached value if it exists

[cinder abyss]

do you have any example?

[hushed spindle]

so in this case you'd be making a

Map<net.minecraft.world.entity.EntityType<?>, EntityType> cache = new HashMap<>()

[cinder abyss]

okay I see

so I just need to iterate through every EntityType nms?

and store them in this map?

[river oracle]

idk how much I vibe with that

that conversion method does absolutely 0 reflection

[hushed spindle]

in your method do

if (cache.containsKey(nmsType)) return cache.get(nmsType);
// do your thing
cache.put(nmsType, actualType);
return actualType;

[river oracle]

you're just moving the store point in memory from one point to another

[hushed spindle]

oh yea you right

turned my brain off there

[river oracle]

please organize your classes properly

    public static EntityType getEntityTypeFromNms(net.minecraft.world.entity.EntityType<?> nmsType){
        ResourceLocation resourceLocation = net.minecraft.world.entity.EntityType.getKey(nmsType);
        String path = resourceLocation.getPath();
        return EntityType.valueOf(path.toUpperCase());
    }``` putting this method in your reflection class is heavily missleading

as the stunning lack of reflection it does

[lost matrix]

  private static final Map<Class<?>, Map<String, Field>> FIELD_CACHE = new HashMap<>();

  public static <T> Object getValue(T instance, String fieldName) throws NoSuchFieldException, IllegalAccessException {
    Map<String, Field> fieldMap = FIELD_CACHE.computeIfAbsent(instance.getClass(), clazz -> new HashMap<>());
    Field field = fieldMap.computeIfAbsent(fieldName, name -> {
      try {
        Field declared = instance.getClass().getDeclaredField(name);
        declared.setAccessible(true);
        return declared;
      } catch (NoSuchFieldException e) {
        throw new RuntimeException(e);
      }
    });
    return field.get(instance);
  }

This basically reduces the field reading to 2 map lookups for every reading after the first one.

[cinder abyss]

okay thanks

[cinder abyss]

It's not permanent

[cinder abyss]

So I use this?

[river oracle]

I wouldn't

[hushed spindle]

not necessary no

[river oracle]

do as 7smile7 suggested

[cinder abyss]

okay thanks

Let's convert every method

like this?
https://paste.md-5.net/kubigoseja.java

@lost matrix

[lost matrix]

Field to the top pls. And make it less DRY. Im seeing a lot of code that can be extracted to a method.

[cinder abyss]

okay thanks

(I switched directly after sending my message the field to the top)

[cinder abyss]

new version

How do i make a cooldown on 10 minutes, with this code:

    private final Plugin6 plugin;

        public SpawnCommand(Plugin6 plugin) {
            this.plugin = plugin;
        }
    @Override
    public boolean onCommand(@NotNull CommandSender sender, @NotNull Command command, @NotNull String s, @NotNull String[] strings) {

        if (sender instanceof Player){
            Player player = (Player) sender;
            Location location = plugin.getConfig().getLocation("spawn");

            if (location != null ){
                player.teleport(location);
                player.sendMessage(Colorize.color("&fDu blev &ekørt &ftil &espawn&f."));
                player.playSound(player.getLocation(), Sound.BLOCK_BELL_USE, 10, 10);
                // Lav cooldown(15 min)
                // Gør så det koster penge
            }else{
                player.sendMessage(Colorize.color("&fLokationen er &cikke &fblevet sat. Kontakt en Admin"));
                System.out.println("PLUGIN6: Der er intet spawnpoint sat.");
            }
        }```

And how do i do, so when you join the server, you spawn at the location i've made, in that code?

[quaint mantle]

HashMaps and UNIX timestamps

[dusky prawn]

Nice, how then?

[quaint mantle]

Thats all you have to learn

[orchid trout]

what exactly are you trying to do?

[glass mauve]

is Hibernate used in combination with plugins and is it recommended if working with a database or should I look at smth else?

[remote swallow]

it can be used with plugins but id recommened doing something lighter

[glass mauve]

for example? also I use Hikari with PostgreSQL if thats important

[remote swallow]

manually writing the sql if you dont have too many things you store, or something like orm lite

[eternal night]

half the time, plain JDBC calls suffice honestly

otherwise, look into e.g. jooq

[remote swallow]

wait

i can english

[glass mauve]

ok thanks :D

[subtle tapir]

Can someone help to setup a CraftBukkit development environment? I'm stuck at https://hub.spigotmc.org/stash/projects/SPIGOT/repos/craftbukkit/browse#making-changes-to-minecraft point 3.

[tender shard]

that repo is private

[eternal night]

You are trying to add a new class from decompiled

what class do you want to edit

[subtle tapir]

oh sorry, i corrected the link

[tender shard]

ok what exactly do you mean with point 3?

[eternal night]

Copy the selected file to the src/main/java/net/minecraft/server folder in CraftBukkit.

[subtle tapir]

Do i have to copy only the server package or the complete net/minecraft into src folder?

[eternal night]

you generally have to copy nothing unless you want to edit a class that does not yet have a patch

what nms class do you want to edit

[subtle tapir]

I specifically want to propose a fix for this issue https://hub.spigotmc.org/jira/projects/SPIGOT/issues/SPIGOT-7547?filter=allissues&orderby=created+DESC%2C+priority+DESC%2C+updated+DESC

But as i created a pr for fixing the docs. another option was suggested

[eternal night]

Yea, but that is not in an NMS class

that is in a craftbukkit class

that is alreaddy there

the entire section "Making Changes to Minecraft" is only needed if you want to edit a class from the mojang server that has no current changes from craftbukkit

[subtle tapir]

So is it normal that the whole project is errored aout in NetBeans?

[eternal night]

did you apply patches

[subtle tapir]

ahhh i forgot that

[eternal night]

yea, that is the first step

[subtle tapir]

I was thinking that those two sections dont depend on each other

[timid berry]

package org.example;

import net.md_5.bungee.api.ProxyServer;
import net.md_5.bungee.api.chat.TextComponent;
import net.md_5.bungee.api.connection.ProxiedPlayer;
import net.md_5.bungee.api.event.PostLoginEvent;
import net.md_5.bungee.api.plugin.Listener;
import net.md_5.bungee.event.EventHandler;

public class events implements Listener {

    @EventHandler
    public void onPostLogin(PostLoginEvent event) {
        for (ProxiedPlayer player : ProxyServer.getInstance().getPlayers()) {
            player.sendMessage(new TextComponent(event.getPlayer().getName() + " has joined the network."));

        }
    }

}

how can i make the server say it instead of the player? the "has joined " part

[rough drift]

you need to send a plugin message to the server and then broadcast there

plugin messages are your own custom data proxy <-> server

[timid berry]

i ment

in the console

the bungee console

is there a way i can do something with the output? like if the output mataches a string, it will do something

[remote swallow]

output of what

[subtle tapir]

Thank you. That solved it.

[timid berry]

the out put of the command

@remote swallow

like

if the output of the command == "https://google.com" it will kick the player

package org.example;

import net.md_5.bungee.api.ProxyServer;
import net.md_5.bungee.api.chat.TextComponent;
import net.md_5.bungee.api.connection.ProxiedPlayer;
import net.md_5.bungee.api.event.PostLoginEvent;
import net.md_5.bungee.api.plugin.Listener;
import net.md_5.bungee.event.EventHandler;

public class events implements Listener {

    @EventHandler
    public void onPostLogin(PostLoginEvent event) {
        for (ProxiedPlayer player : ProxyServer.getInstance().getPlayers()) {
            player.sendMessage(new TextComponent(event.getPlayer().getName() + " has joined the network."));
            String namses = event.getPlayer().getName();
            String commandcheck = "domain " + namses;
            ProxyServer.getInstance().getPluginManager().dispatchCommand(ProxyServer.getInstance().getConsole(), commandcheck);
        }


    }

}

[remote swallow]

what

i mean sure but idk why a name would be like that

[timid berry]

what

its running the command

/domain {user}

i want it so

if the commands response is https://google.com

it will kick the player

with reason

"this domain is not allowed"

[remote swallow]

uh

[timid berry]

lmao

[remote swallow]

sure

ideally you wouldnt be wanting to check the result of a command like that

you would have a method the command just calls

[timid berry]

everyplayer has a domain

but i will kick players with bad domain

[remote swallow]

are you talking about their host ip?

[timid berry]

no

the command /domain is from another plugin

[remote swallow]

does said plugin have an api?

[timid berry]

prolly not

[remote swallow]

what plugin is it

[timid berry]

blud

its complicated

is it possible to get the response from the command

[remote swallow]

yes but that is most likely bad design

[timid berry]

just tell me how to do it

[remote swallow]

run the command as console and listen to the logs

which you shouldnt have to do, almost ever

[timid berry]

oh aight

the plugin has an api folder in its source

maybe i can get the response from there

[remote swallow]

name the plugin

[timid berry]

its too sketchy

[remote swallow]

just say it

[timid berry]

nvm the api folder has no mention of said domain

[remote swallow]

if you dont want to say it here dm it me and ill check if it has an api you can use

[timid berry]

na its fine i dosent have one

[remote swallow]

somehow im doubting that

[timid berry]

getLatestLogEntry

what does this do?

[remote swallow]

where is the method

[timid berry]

i dont know

where can i find methods?

[remote swallow]

so how do you expect me to know what it does

[lament tree]

💀

[timid berry]

yah

where can i find methods?

[remote swallow]

what are you trying to copy

[timid berry]

i just found some weird guide

[remote swallow]

in classes

[timid berry]

is there documentation on it

[remote swallow]

does it haev anything before it

eg something.getLatestLogEntry

[timid berry]

no

i made it up

now

is there a website for documentation

for the different methods

[remote swallow]

no

because thats a custom method

you make it

[timid berry]

right

is there a website for the regular methods

[remote swallow]

yes

[undone axle]

https://ci.md-5.net/job/BungeeCord/ws/api/target/apidocs/index.html

[timid berry]

okay

so for the log file thing

i would make the plugin

open latest.log

and see if the last output

matches what i want

right

[remote swallow]

no you would probably want to read the print stream

why are you so scared of just saying the plugin name

[timid berry]

https://tenor.com/view/dance-dance-if-youre-a-npc-npc-npc-dance-lil4g-gif-26266822

[remote swallow]

just dm me the plugin name

[timid berry]

na its fine

ill read the output stream

[remote swallow]

you keep just making this an xy issue

[timid berry]

lemme make a spigot thread

[remote swallow]

you confuse me so much

[timid berry]

cant i do

String consoleOutput = dispatchCommandAndGetOutput(ProxyServer.getInstance().getConsole(), commandCheck);

and then check the varibles match

rip

[remote swallow]

you are making this so much harder bt just not saying the plugin name

dont even have to say it here

[timid berry]

bro im gonna get banned

[remote swallow]

dm it me

[timid berry]

its for cracked minecraft stuff

[ivory sleet]

:(

[timid berry]

:(

yah anyways

it dosent have an api

for domain checker

so idk how i can get the output of the /domain command

and do something with it

damn

Are noSQL databases better than mySQL databases? Or what are the pros and cons of both?

[quaint mantle]

Duplicate code fragment detected. Do you want to extract it to a function?

[proud badge]

no because im looping different objects

[quaint mantle]

no

}
}

duplicate code fragment

[ivory sleet]

Structured vs unstructured

I assume you mean mongo by nosql?

[quaint mantle]

it hurts my eyes to even read that sh!t

[inner mulch]

I guess, im not that experienced

[ivory sleet]

The big advantage with mysql is that u can query just a single field of data from a specific user

I guess data analysis can be easier with mysql, altho there are tools to do with mongo as well

[inner mulch]

May I ask, whats your favourite?

[ivory sleet]

I don’t have a favorite

I believe all these database tools like mongo, postgre, cassandra, google spreadsheet (yes lol) and redis have different usecases

[inner mulch]

Isnt mongo better, if i dont want to create a new table for every single thing, because i huess you can just add data in an unorganized DB?

[ivory sleet]

I mean if you only care about storing blobs of data for each user persistently, then yeah mongo prob is fine

[inner mulch]

Or for saving the bans of a player as everyone has a different amount of prior bans, with SQL you would need a new row each time?

[ivory sleet]

you mean like logging previous bans?

[opal elbow]

I use Maven, and therefore, I built my own Spigot on version 1.20.2. However, I am unable to find any methods related to packets. My Maven configuration looks like this:

    <dependencies>
        <dependency>
            <groupId>org.spigotmc</groupId>
            <artifactId>spigot-api</artifactId>
            <version>1.20.2-R0.1-SNAPSHOT</version>
            <scope>provided</scope>
        </dependency>
    </dependencies>```

[inner mulch]

Yeah

[ivory sleet]

Mongo is fine

[shadow night]

That's because the spigot api has nothing related to packets

[inner mulch]

No no, i mean if this would be the ideal use case, as im interested in using both

[opal elbow]

How can I then work with Packets?

[shadow night]

You either need a library or nms

[opal elbow]

Do you have any tutorials for me please?

[chrome beacon]

?nms

[undone axle]

https://blog.jeff-media.com/nms-use-mojang-mappings-for-your-spigot-plugins/

Thank you

[cinder abyss]

Hello, how can I check if there is grass between two entities?

[chrome beacon]

You can rayTraceBlocks

[cinder abyss]

okay thanks

[cinder abyss]

which one?

[chrome beacon]

The one you want to use / fits your use case

[cinder abyss]

the one who enabled me to check if there is grass between two entities

[chrome beacon]

both do

[cinder abyss]

idk if I need to select one in bukkit world, or one in bukkit player...

[chrome beacon]

Depends on what your goal is

[cinder abyss]

I told you x)

to check if there is grass between two entities

a player and a LivingEntity

[chrome beacon]

sigh

Why do you need to check if there's grass between two entities

[cinder abyss]

to make the player attack the entity

[chrome beacon]

Yeah had a feeling that was the case

use the player one

[cinder abyss]

x)

okay thanks

[cinder abyss]

Hello, how can I get player weapon damage and if the player is reloading his weapon?

[quaint mantle]

Does anyone here casually have all the entities head sizes?

not me

[inner mulch]

wdym by reloading?

Are you talking about bows?

[cinder abyss]

swords

also axes

[inner mulch]

wdym by reloading then?

[cinder abyss]

this

[inner mulch]

hm, im not sure about this one sorry

[cinder abyss]

okay

maybe it's clientside

[inner mulch]

but you can get the damage on the EntityDamageEntityEvent

i think

[cinder abyss]

I want to create a EntityDamageEntityEvent

[remote swallow]

that is recharging the crit attack cooldown

[inner mulch]

ok

[cinder abyss]

yes

[vocal cloud]

There is an arm cooldown not sure if spigot has a method for it

[cinder abyss]

So, according to 1.9+ pvp system, how can I make a method to deal damages to an entity based on player's weapon attack damage and attack cooldown? (if cooldown is charged, the player inflict the weapon damage (there isn't critical in this case) and if it isn't, the player inflict the damage when you spam (I think it's 0.5 PV?))

[cinder abyss]

found!

[vocal cloud]

There you go

[cinder abyss]

so I need to get weapon damage

does someone know? please

I know I need to deal with attributesModifiers and Generic AttackDamage but idk how

[subtle tapir]

[quaint mantle]

how do i make a normal java event a bukkit event

[river oracle]

what are "normal java events"

unless you're talking about swing I don't believe any such things exist

[quaint mantle]

https://javadoc.io/doc/org.apache.logging.log4j/log4j-1.2-api/2.13.2/org/apache/log4j/spi/LoggingEvent.html

[river oracle]

Step 1. Listen to the event using Log4J's API
Step 2. Create a Bukkit Event that provides the relevant similar data
Step 3. Use the listener you created in Step 1 to call the event you created in Step 3.
Step 4. Profit

[quaint mantle]

which listener

[river oracle]

https://cdn.discordapp.com/emojis/513348729110134785.webp?size=48&name=Shrug&quality=lossless

did a bit of research don't think you can/should use this class

doesn't seem like it does what you expect it to

[quaint mantle]

ok what should i use then

[river oracle]

idk I'm not an expert in the Log4j API

[quaint mantle]

i just need a log event

[river oracle]

I highly doubt they have some listenable event that triggers every time something is logged too

seems insanely resource intensive for little to no gain

[river oracle]

why

[quaint mantle]

i need a log event

[river oracle]

why'

[quaint mantle]

i want one

[river oracle]

?xyproblem

whatever

?xy

[undone axle]

http://xyproblem.info/

[quaint mantle]

i literally just want a log event

[river oracle]

its useless

don't

[quaint mantle]

how

[river oracle]

this really screams xy problem

"i want one" is not a very good reason

a LogEvent in of itself seems pretty useless too

[quaint mantle]

why should there be a reason

[river oracle]

because if you want to do something like this there should be a reason you want to do it other than "eh i want to ig"

[quaint mantle]

ok but why would you want to know

[river oracle]

because it really seems like xyproblem

by knowing x its very likely you don't need to do y

[quaint mantle]

i want a bukkit event that will be called when ever a log gets sent to the console

[river oracle]

why that seems utterly useless

[quaint mantle]

cuz i want it

[minor junco]

No man, absolutely not 😭

[quaint mantle]

lol

Mixin?

[wet breach]

So you want to log the log?

Just fyi you can always swap out the handler for log levels or register an additional handler etc

But you seem to be new so

[sterile flicker]

how do I make
the net.minecraft(nms) package for 1.16.5 available for use

?

[wet breach]

?bootloader

[chrome beacon]

Import the Spigot artifact

[wet breach]

Hmmm forgot the name

[chrome beacon]

After running BuildTools

[wet breach]

You cant just import directly anymore

[chrome beacon]

1.16

[quaint mantle]

In maven its ez

[chrome beacon]

Is older than 1.17.1 it has no mojmaps (with Spigot)

[wet breach]

Ah

[wet breach]

Its not a maven issue that i was referring to

[quaint mantle]

Ok

[sterile flicker]

Can I use something from my mod, meaning, is there something similar when it comes to plugins in terms of custom entities? For example, there's a snake entity, and there's code to draw/animate snake tongue using OpenGL Can this be utilized in a plugin with some resource pack (which I want to create from the mod's assets folder)? However, I also understand that many things may not be supported.

So it is possible with nms?

[chrome beacon]

No nms is server side

[wet breach]

Yes just not easy and you need to get creative.

[chrome beacon]

If you're drawing with pure OpenGL you can update to a newer version and use GLSL Shaders in a ResourcePack

But yeah it does require you to be creative

[sterile flicker]

where is the buildtools artifact located I can't find the spigot-api folder in the spigot folder

[quaint mantle]

Someone has a vid on youtube of importing Blender 3d objs in minecraft via JavaPlugin.

I think they did it with resource pack

[sterile flicker]

and it just didn't end

[quaint mantle]

Anyways hypixel makes their custom pets with resource pack

[sterile flicker]

do I need exactly the artifact in the spigot-api folder to support nms?

[quaint mantle]

Yes need to be exact version as your spigot

Idk what u mean by spigot-api folder. Just download the build tools version u need and run it lol

[sterile flicker]

I have is the core right in the buildtools folder

is there a tutorial on this for 1.16.5(nms)?

[wet breach]

No

[echo basalt]

there are mappings for it

so just look n learn

[sterile flicker]

i found https://www.spigotmc.org/threads/custom-entityplayer-class-with-skins-that-take-damage.437594/

        }
    }``` setArrowsOnEntity(entityPlayer, 20);

``` how to update the player state

at the moment, the arrows only appear when I shoot myself and yes I use nms

full code: https://pastebin.com/V63H8DEM

solved: solution is - ```DataWatcher dataWatcher = entityPlayer.getDataWatcher();

is there an event for when a player has finished downloading the custom server rescource pack

[agile hollow]

    public void onPlayerDeath(PlayerDeathEvent event) {
        Player player = event.getEntity();
        GamePlayers1.remove(player.getUniqueId());
        GameNames1.remove(player);
        if (event.getEntity().getLastDamageCause() instanceof EntityDamageByEntityEvent) {
            EntityDamageByEntityEvent nEvent = (EntityDamageByEntityEvent) event
                    .getEntity().getLastDamageCause();

            if ((nEvent.getDamager() instanceof Player)) {
                Player p = (Player) nEvent.getDamager();
                p.sendMessage("Hai assassinato " + player.getName());
                player.sendMessage("Sei stato assassinato da " + p.getName());
                if(GamePlayers1.size()==1) {
                    p.sendMessage("Hai vinto il minigame!");
                }
            }
        }
    }```

why it isn't removing the value in the 2 List GamePlayers1 and GameNames1?

[lost matrix]

Did you check if this listener is actually called?

[agile hollow]

yes because that listener to the think without the using of the List

[lost matrix]

Yes, the resourcepack event fires multiple times with different states.

[agile hollow]

for example it send the messages to the 2 players without problems

[lost matrix]

What makes you think the player wasnt removed?
Im guessing that you create multiple instances of your Listener class.

[agile hollow]

because i make the command /jqueue and if the player is within that list it send a message and i'm getting that message

for clone a List from one to another it's like that right? GamePlayers1.addAll(QueuePlayers); Because i'm thinking the problem is here

[lost matrix]

This doesnt remove previous entries. So its not cloning. It simply adds all objects from ListA into ListB

[agile hollow]

but it add different objects right?

because i clear the old list after doing that action

[lost matrix]

Different from what?

[agile hollow]

like 1, 2, 3 etc and not 1 2 3 4 in only 1 object

[lost matrix]

?

Just show me your command and listener classes pls

?paste

[undone axle]

Alright, now the command

[agile hollow]

[lost matrix]

Field and method names start with lower case characters pls.

[agile hollow]

ok sry

i will convert all rn

[celest notch]

for some reason i can't import nms in 1.20.4

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

[wet breach]

?bootstrap

[undone axle]

Bootstrap Jar
The main spigot-1.18.jar is now a bootstrap jar which contains all libraries. You cannot directly depend on this jar. You should depend on Spigot/Spigot-API/target/spigot-api-1.18-R0.1-SNAPSHOT-shaded.jar, or the entire contents of the bundler directory from your server, or use a dependency manager such as Maven or Gradle to handle this automatically.

Please read the release notes for further information: https://www.spigotmc.org/threads/9-years-of-spigotmc-spigot-bungeecord-1-18-1-18-1-release.534760/#post-4305163

[celest notch]

im confused how do i change my xml

[lost matrix]

I cant make out the problem.
Check the player names before and after dying.
Btw: Every collection (Lists, Sets, Maps etc) should always be private, final and should have no getter or setter.
That is very important.

[lost matrix]

Text editor. Preferably an IDE.

[celest notch]

ik thta

*that

but how do I fix my problem with nms not working

[lost matrix]

Did you run BuildTools for 1.20.4 ?
Otherwise you have no access to nms.

[celest notch]

yes i did

java -jar BuildTools.jar --rev 1.20.4 --remapped

[lost matrix]

Then check if your versioning is correct.

[celest notch]

its 1.20.4-R0.1-SNAPSHOT right

[lost matrix]

Let me check

1.20.4-R0.1-SNAPSHOT

Yeah looks about right

Then invalidate caches and restart your IDE

[chrome beacon]

So what nms class are you trying to access

in which package

[celest notch]

basically my issue is im missing classes like CraftPlayer

[agile hollow]

@lost matrix ok i make the loop of all the player first and after killing a player and nothing changed from before and after the kill

[celest notch]

that worked thank you

[lost matrix]

How did you check?

[onyx fjord]

any way to change datapack priority either in server config or thru the api?

[agile hollow]

on the command /jqueue when he send the error send to me the UUIDS too

a done it before and after

[lost matrix]

Show the EnjoyingEvent#getQueueManager() method pls

Wait, show me your JavaPlugin class all together

[agile hollow]

the main class?

[lost matrix]

Sure

Im guessing its EnjoyingEvent, right?

[agile hollow]

yes

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

[lost matrix]

As predicted

[agile hollow]

oh

sry

[lost matrix]

All good. Btw a manager class should not be a listener.
You should separate your concerns there 👍

[agile hollow]

ok thx and sry for that stupid error

[agile hollow]

sry for ping you another time but now i'm thining on what you said erlyer about to make the List private but how can i reach in a diff class if i make the List private?

[lost matrix]

You add a mutator method with a proper name.

public void addPlayerToQueue(Player player) {
}

public boolean isInQueue(Player player) {
}

public int getQueueSize() {
}

And for bulk (read only) operations you can expose an immutable copy

public List<UUID> getAllQueuedPlayers() {
  return List.copyOf(this.playerQueue);
}

[agile hollow]

oh ok now i understand thx

[round finch]

Fun random fact java has some weird queue class

[lost matrix]

It has a bunch of weird queue classes. And even some quite unknown gem queues for multithreading.

[round finch]

https://docs.oracle.com/javase/8/docs/api/java/util/Queue.html

[round finch]

Oh really..!!
That's sounds cool

[tall furnace]

So I've been working on a custom map renderer, but I find that the renderer no longer affects the map once the map is scaled. Also map initialize event is not called when a map is scaled, even though it resets the exploration.

How do I detect when a map gets scaled so I can update the renderer?

No that event is fired too early. Use the PostLoginEvent

Anyone knows how to alter the attack speed of any monster, e.g. zombies ?

[peak depot]

In the plugin yml can you only use x.x.x or can I do smth like 23w52a

[chrome beacon]

For what?

[peak depot]

version

[chrome beacon]

Your version can be anything but I do recommend following semantic versioning

[sterile flicker]

it is impossible to use GL11 drawing methods in spigot?

[rough drift]

Is the spigot server the client

it doesn't even have LWJGL as a dependency

[sterile flicker]

I have a tileentity in my forge mod that creates rotating nbt crystal around an entity and I want to make the same one in a spigot

Is there really no way?

[rough drift]

you can summon an entity with nbt data and render it with the mod

but you can't in spigot

[sterile flicker]

but then why do I find nbt And titleentity classes in nms

[rough drift]

.

[sterile flicker]

so I cant do something close to that?

[rough drift]

... you can?

[chrome beacon]

The server cannot render stuff

[rough drift]

What part of "you can summon an entity with custom nbt data and render it with your mod" is unclear

[chrome beacon]

Rendering happens on the client

[rough drift]

^

[sterile flicker]

can I draw something with texture pack?

although it just sets the textures

[peak depot]

for nms how can I do create a ClientInformation for an NPC thats my code so far```java
package eu.hylix;

import com.mojang.authlib.GameProfile;
import net.minecraft.server.MinecraftServer;
import net.minecraft.server.level.ServerLevel;
import net.minecraft.server.level.ServerPlayer;

import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.craftbukkit.v1_20_R3.entity.CraftPlayer;

import java.util.UUID;

public class CreateCommand implements CommandExecutor {
@Override
public boolean onCommand(CommandSender sender, Command command, String s, String[] args) {
if(sender instanceof Player player) {
CraftPlayer craftPlayer = (CraftPlayer) player;
ServerPlayer sp = craftPlayer.getHandle();

        MinecraftServer server = sp.getServer();
        ServerLevel level = sp.serverLevel().getLevel();
        GameProfile gameProfile = new GameProfile(UUID.randomUUID(), "Billy Bob"),


        ServerPlayer npc = new ServerPlayer(server, level, gameProfile, );
    }
    return false;
}

}

[sterile flicker]

if there was something that would allow you to draw on the client side on spigot server

[rough drift]

there isn't

it's literally not a thing

I mean I know how to do something similar

[chrome beacon]

TexturePacks are called ResourcePacks now because they can contain more than just textures now

[rough drift]

but uhhh... work secret ;-;

[chrome beacon]

You can use shaders to draw stuff

[sterile flicker]

shaders are created via glsl and that's it. I cant use java code in shaders to draw something

[chrome beacon]

Yeah I'm aware

[sterile flicker]

but they still don't contain what I need, yes?

[chrome beacon]

They can contain shaders

[quaint mantle]

If I rotate a DisplayEntity through the Transformation, 180 degrees (degrees to radians), it does in fact rotate 180 but the issue is that it also modifies the y translation.

How may I rotate any axis (x,y,z) without affecting translation?

[sterile flicker]

but packets allow me to draw something on the client side?

or do I have a wrong understanding of this

[chrome beacon]

No

Packets just send basic information like: There is a zombie at x,y,z

The client then renders a zombie at that location

[quaint mantle]

Resourcepack models don't suffer this

[peak depot]

    public class CreateCommand implements CommandExecutor {
        @Override
        public boolean onCommand(CommandSender sender, Command command, String s, String[] args) {

                CraftPlayer craftPlayer = (CraftPlayer) player;
                ServerPlayer sp = craftPlayer.getHandle();

                MinecraftServer server = sp.getServer();
                ServerLevel level = sp.serverLevel().getLevel();
                GameProfile gameProfile = new GameProfile(UUID.randomUUID(), "Billy Bob");
                ClientInformation info = new ClientInformation("de", 1, ChatVisiblity.FULL, true, 2, HumanoidArm.RIGHT, true, true);

                ServerGamePacketListener ps = sp.connection;
                ps.

            }
            return false;
        }
    }
``` there was .send for ps but now no longer anybody know what it is now?

[chrome beacon]

Look at Mojangs code

[peak depot]

you got a link for me?

[chrome beacon]

It's in your IDE

Look at the nms classes and see how Mojang uses them

[peak depot]

how can I see where its used?

I use IntelliJ

[chrome beacon]

The Spigot tooling isn't great for that but you can probably guess

[peak depot]

what would you recommend then

[chrome beacon]

A modding environment will probably work better

Personally I just use my mod project to quickly view decomp sources

[south mason]

I'm writing a plugin for my own chat and would like to add PAPI support, how can this be implemented?

[quaint mantle]

You could, however, virtually render it on server, useless, but possible

[chrome beacon]

You'd use their API

check the documentation

[odd turtle]

indeed. Obviously I went to google before coming here

[odd turtle]

so my question is currently unanswered

[chrome beacon]

The answer is yes, you can use nms or a bukkit task

it's up to you

[odd turtle]

Right well with nms, how would I do that? I can't seem to find any up to date 'documentation' or examples

[chrome beacon]

nms is undocumented

Which is why it's more of an advanced topic

You need to be able to read the decompiled code and figure out what it does

In your case it really isn't that hard, just look at the attack goal and how it's stored in the entity

oh and when you're asking for help with nms it's very important that you specify the exact version you need help with

and the more details you can provide the better

[odd turtle]

Right thanks, I'll figure it out, thank you for your time

[quaint mantle]

Because of obfuscation some methods and fields might be also different between versions, I usually check older versions and try to find references to find the new name

how do i hide player from playerlist? i tried:
player.setCustomName(null);
player.setPlayerListName(null);

and none of this is working

[chrome beacon]

That requires some packet trickery

or if you want to hide the player entierly you can use the hidePlayer method

[kindred trellis]

how do i do that?

[chrome beacon]

You'd send the player info remove packet

using nms or your packet lib of choice

[kindred trellis]

thanksss

i dont have PacketPlayOutPlayerInfo what do i do to be able to use that?

[chrome beacon]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/inventory/RecipeChoice.ExactChoice.html

[carmine mica]

exact choice doesn't work on spigot for shapeless recipes

[somber night]

it worked on a different item though

here is the other working code https://paste.md-5.net/uhidapeqah.cs

[carmine mica]

what is tpItem?

[somber night]

a custom item that also works

[carmine mica]

right, but do other items of the same type also work in its place?

[somber night]

tpItem is a netherstar, if thats what you mean
and no, others dont work

[carmine mica]

what server are you running?

do /version and show the output

[somber night]

This server is running Paper version git-Paper-81 (MC: 1.19) (Implementing API version 1.19-R0.1-SNAPSHOT) (Git: 86f87ba)
You are running the latest version

[chrome beacon]

._.

[carmine mica]

yeah, they work on paper, they don't work on spigot (which is why I italicized spigot earlier)

[somber night]

a

my bad then i guess

[sterile flicker]

is there the same extension id("xyz.jpenilla.run-paper") only for the spigot, I just have the error com.destroystokyo.paper.exception.ServerInternalException: Attempted to place a tile entity (com.sumeru.bosses.tileentity.TileEntityBaseBeehive@a0b5175) at 0,0,0 (Block{minecraft:air}) where there was no entity tile! [20:50:19 WARN]: Chunk coordinates: -16,-240 [20:50:19 WARN]: although I am sure that it is not related to the paper but to an error in the code, but I want to fully use the spigot to get support here

[chrome beacon]

Looks like you forced a tile entity where there shouldn't be one

[sterile flicker]

code: ```package com.sumeru.bosses.tileentity;

import net.minecraft.server.v1_16_R3.Entity;
import net.minecraft.server.v1_16_R3.IBlockData;
import net.minecraft.server.v1_16_R3.TileEntityBeehive;

import java.util.List;

public class TileEntityBaseBeehive extends TileEntityBeehive {

public TileEntityBaseBeehive() {
}

@Override
public void addBee(Entity entity, boolean flag) {
    super.addBee(entity, flag);
}

@Override
public List<Entity> releaseBees(IBlockData blockData, ReleaseStatus releaseStatus, boolean force) {
    return super.releaseBees(blockData, releaseStatus, force);
}

}``` WorldServer nmsWorld = ((CraftWorld) world).getHandle();
nmsWorld.setTileEntity(Teleportation.getPlayerBlockPosition(player), new TileEntityBaseBeehive());

I do not know how it works as there are very few tutorials on this on the Internet

[cinder abyss]

Hello, how can I get weapon attack speed? (directly from his modifiers, not from Material modifiers)

[chrome beacon]

so I was right?

Not sure what you want me to do

[sterile flicker]

but I'm creating a tile entity right on the player's coordinates to see what it is in general. I expect to see a beehive

[sterile flicker]

so that you can tell me how to do it correctly

        Location location = player.getLocation();

        int x = location.getBlockX();
        int y = location.getBlockY();
        int z = location.getBlockZ();

        return new BlockPosition(x, y, z);
    }```

[carmine mica]

what on earth are you trying to do with a custom tile entity?

[chrome beacon]

air can not have the tile enity of a bee hive

only bee hive can be a bee hive

[sterile flicker]

Just summon him and explore and then if I find a good tutorial to do something, although I have a very bad understanding of tile entity

[carmine mica]

yeah, tile entities can only exist at locations that have the correct block type

a chest tile entity can only exist at the location of a chest

[chrome beacon]

get the attack speed attribute from the item meta

[sterile flicker]

So how do I summon him correctly

[chrome beacon]

Why are you making your own tile entity

[sterile flicker]

But how else?

[chrome beacon]

how else what

[sterile flicker]

sorry translator

how otherwise?

[chrome beacon]

what are you trying to do

[sterile flicker]

I have already said above

[chrome beacon]

?

What is the goal

[sterile flicker]

to understand what a tile entity is and what can be done with it, since I'm making a plugin for mobs and maybe it will come in handy somehow

[chrome beacon]

a tile entity is a block that contains extra data

[cinder abyss]

it doesn't work

I get an empty list

[sterile flicker]

what data can it contain?

[cinder abyss]

player.getInventory().getItemInMainHand().getItemMeta().getAttributeModifiers(EquipmentSlot.HAND).get(Attribute.GENERIC_ATTACK_SPEED);```

[chrome beacon]

A chest for example has the items in it

[sterile flicker]

that is, do I need to put items in a chest using the tile entity of chest

[chrome beacon]

Spigot has api for that

[peak depot]

https://paste.md-5.net/oyilokodiy.cs, https://paste.md-5.net/hezuwoxuno.java anyone know why it is null?

[chrome beacon]

Why would it have a connection

It's not a real player

[peak depot]

but how would I spawn it in then?

[chrome beacon]

If you're just copy pasting npc code from the internet you might as well just use an NPC lib like Citizens

[peak depot]

but sp is the real player so it shouldnt be null or am i stupid

ps.send(new ClientboundAddEntityPacket(sp)); thats line 40

[sterile flicker]

I still want to experiment with this, if I set a tile entity of the hive where there is already a hive, will it work?

[chrome beacon]

it does not have a connection

why you ask, because it's not a real player

so nothing is connected to it

[echo basalt]

you gotta fake a connection

[sterile flicker]

I still don't understand in what position should I spawn it?

[echo basalt]

don't ask why

the packet seems to get some data from the connection

[peak depot]

CraftPlayer craftPlayer = (CraftPlayer) player;
ServerPlayer sp = craftPlayer.getHandle(); but that means sp has a connection or not

[echo basalt]

now here's the funny ass thing

why are you sending the player to itself

[chrome beacon]

try it and see

I don't know exactly how the tile entity check is implemented

[chrome beacon]

That has nothing to do with the connection

[sterile flicker]

https://tryitands.ee/

[echo basalt]

?tryandsee

[undone axle]

https://tryitands.ee/

[peak depot]

so what is the connection if not sp.connection?

[chrome beacon]

that is the connection variable

[peak depot]

yes but the Real player has a real connection or not?

[echo basalt]

it has

[chrome beacon]

Every real player has a connection

[peak depot]

so why are you telling me that real player doesnt have one

[chrome beacon]

I haven't done that

[glass mauve]

what is the preferred way of parsing a time from command args?
like /command days hours minutes seconds
or just one arg in some specific format?

[echo basalt]

the npc doesn't have a connection

it's trying to get data from it on the tab packet

[echo basalt]

7d2h1m15s

[glass mauve]

thanks

[peak depot]

npc.connection = ps; but this would give it a real connection or not

[echo basalt]

it would

[chrome beacon]

but why would you do that

[echo basalt]

you need to emulate a fake connection

[chrome beacon]

^^

[echo basalt]

to retain API (plugins sending packets)

just make the packets go nowhere

[peak depot]

npc.connection = new ServerGamePacketListenerImpl(server, new Connection(PacketFlow.SERVERBOUND), npc, CommonListenerCookie.createInitial(gameProfile)); does this look about right?

[echo basalt]

extend the class and make your own impl

you might be able to pass null a bunch

[peak depot]

all of them have a notnullable

[echo basalt]

I guess that works

[peak depot]

to all set them to null?

[echo basalt]

no

your suggestion

try and see

[peak depot]

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

[echo basalt]

radical ok

What if

you just make a DummyServerPlayerConnection class

that implements the ServerPlayerConnection interface

[peak depot]

but where do I need the ServerPlayerConnection like npc.connection takes ServerGamePacketListenerImpl

[echo basalt]

why does the interface exist

[peak depot]

nah bro fr I dont get it rn

[chrome beacon]

Yeah might want to use Citizens

[echo basalt]

nah

this is just annoying

but it's doable

[chrome beacon]

ofc it's doable but there's no need to reinvent the wheel

[echo basalt]

it'll probably break api but you can just create the packet in another way and skip the connection entirely

[peak depot]

do you guys know what this.n is? so maby i can trace it back and fix it

[echo basalt]

Is it possible to cancel a task created via Bukkit.getScheduler().scheduleSyncRepeatingTask(...) from within the task? It seems like it loops endlessly if I structure my code like this:

private int taskId;

...

this.taskId = Bukkit.getScheduler().scheduleSyncRepeatingTask(plugin, () -> { ... Bukkit.getScheduler().cancelTask(taskId)}, 0, 5);

My guess is, that I made the usual mistake thinking that taskId is already given the value of the task but this is done after the task executes. Am I right with that?

[peak depot]

Isnt there cancel()?

[grim dock]

Not inside the lamda, no

[glad prawn]

declare your parameter

[chrome beacon]

?scheduling

[undone axle]

https://www.spigotmc.org/wiki/scheduler-programming/

[grim dock]

I think I already found a solution. Instead of Bukkit.getScheduler().scheduleSyncRepeatingTask() I can use Bukkit.getScheduler().runTaskTimer(plugin, new BukkitRunnable() {...}, 0,1)

In the BukkitRunnable I can use cancel()

[chrome beacon]

That would be deprecated

[grim dock]

True

[chrome beacon]

Just read the wiki page ._.

[grim dock]

Will do. Thank you.

[glass chasm]

Ive looked on there forever im just confused at how the packet structure works since i think the wiki is lying to me

[chrome beacon]

It isn't

Do make sure you select the correct version of the wiki

also if you're using protocol lib it will wrap certain data for you

[fickle mantle]

Hey, I was trying to run buildtools for 1.20.4, but I get that Exception: org.eclipse.jgit.api.errors.TransportException: Tag mismatch! I already whitelisted https://hub.spigotmc.org/ to my AV but nothing worked

send the full error and what command you ran

[fickle mantle]

https://pastebin.com/cPEkJ57c I used: java -jar BuildTools.jar --rev 1.20.4

WTF is wrong with intellij

kept freezing

till i somehow fixed it

[astral scroll]

im needing a name

for my plugin

its utility, so

idk

how can i create ideas?

i tried with AI but nothing

[lost matrix]

EssentialsY

[eternal oxide]

Virus

[astral scroll]

sure

anvm

i thought of Flux

do i need to declare package on kotlin?

literally first kotlin project

[lost matrix]

What does that even mean?

[dry hazel]

you can have package-less classes, not recommended though

[astral scroll]

package org.bukkit.inventory lets say

[lost matrix]

Do you mean for imports or your own classes?

[eternal oxide]

his own

Java does at teh top

[astral scroll]

yea

[lost matrix]

I mean sure. Declare the package at the top as well.

[rough harness]

anyone know how i could hid the paper but keep the text

[chrome beacon]

Custom item model without a texture?

[quaint mantle]

Is EntityPlaceEvent supposed to be called when you spawn an entity using an egg?

Nvm

Just read the javadoc

[quaint hedge]

how can i get NeworkManager from PlayerConnection?

im trying to create a NPC

[chrome beacon]

sigh not another one

[quaint hedge]

why? its a problem?

[chrome beacon]

I don't mean to be rude, I'm just tired

[rough harness]

ok can some one help me with that using oraxen plugin
my dev quit on me with life stuff going on so i am trying to do this by my self

[chrome beacon]

try the oraxen discord

[chrome beacon]

What version are you making your plugin for

[quaint hedge]

1.20.4

[chrome beacon]

I'm guessing you're following an outdated guide

[quaint hedge]

something like that

i upgraded my server to this version

[chrome beacon]

If you're trying to send a packet it's connection.connection

great naming by Mojang on that one

[quaint hedge]

from what i understand i need to create a method call inject that use Channel and later send packets

but the problem is to get the Channel from PlayerConnecion

[chrome beacon]

Are you trying to listen to packets?

[quaint hedge]

yes in order to make NPCInteractEvent

[chrome beacon]

Yeah then you need to inject in to the netty pipeline

Honestly though just use Citizens it'll save you a lot of time

[peak depot]

well I tryed it and it works for my need ish like I want to set a diffrent skin then name with the api do you know how to do that

[quaint hedge]

i want to learn not using other plugins

[quaint hedge]

so how can i get the Channel?

[chrome beacon]

There should be a skin trait you can use to change the skin

[quaint hedge]

i try to searh in PlayerConnection class

and nothing

[rough harness]

thanks

[quaint hedge]

there is no somthing that can help me with NetworkManager

[chrome beacon]

I hope you're not writing in unmapped

that would be a pain to do

[celest notch]

Is it possible to use a local path for a resource pack on a server I do not want to depend on hosting sites that may go down

[chrome beacon]

You can host the file yourself

[quaint hedge]

can you explain me the map unmap thing?

i understood its something that very helpful

[celest notch]

how would i do that would i set the path in the config to like

/home/user/resourcepack/resourcepack1.zip

would that work

[chrome beacon]

Minecrafts code is obfuscated. Mojang provides obfuscation mappings that undos (maps) the obfuscation of method and fields

[chrome beacon]

No

[celest notch]

ok how would i do it

[chrome beacon]

You'd run a local web server that can provide the file

[quaint hedge]

and how do i use that?

[chrome beacon]

?nms

[undone axle]

https://blog.jeff-media.com/nms-use-mojang-mappings-for-your-spigot-plugins/

[celest notch]

thats annoying since i want to possibly upload the plugin

most users dont know how to do that

[astral scroll]

how do i make

a static method

on kotlin

static fun doesnt work :(

[chrome beacon]

You can include a simple web server in your plugin

[celest notch]

YOU CAN DO THAT?

oops

[chrome beacon]

yes ofc

[dry hazel]

move it to the top-level or put it into a companion object

[quaint hedge]

no in mapping

[chrome beacon]

?

[quaint hedge]

or the nms is already mapping?

[chrome beacon]

If you've followed the guide then the mappings are applied

[celest notch]

does the url box in the server.properties support localhost

[chrome beacon]

No you'd need the public address

[celest notch]

127.0.0.1?

[chrome beacon]

The client needs to know where to download the resource pack from

[quaint hedge]

public static Map<UUID, Channel> channels = new HashMap<>();
private int count = 0;
Channel channel;

    private Channel getChannel(Player player) {
        try {
            PlayerConnection connection = ((CraftPlayer) player).getHandle().c;

            Field GetNetworkManager = PlayerConnection.class.getDeclaredField("h");
            GetNetworkManager.setAccessible(true);

            NetworkManager networkManager = (NetworkManager) GetNetworkManager.get(connection);


// Get the Channel object from the NetworkManager object
            return networkManager.n;
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }

public void inject(Player player) {

    CraftPlayer craftPlayer = (CraftPlayer) player;
    //Entity Player playerconnection, playerConnection network manager, Network manager channel
    channel = getChannel(player);
    channels.put(player.getUniqueId(), channel);
    System.out.println(player.getDisplayName() + " Added to pipeline");

    if (channel.pipeline().get("PacketInjector") != null) {
        return;
    }

    channel.pipeline().addAfter("decoder", "PacketInjector", new MessageToMessageDecoder<PacketPlayInUseEntity>() {

        @Override
        protected void decode(ChannelHandlerContext channel, PacketPlayInUseEntity packet, List<Object> arg) throws Exception {
            arg.add(packet);
            readPacket(player, packet);
        }
    });
}

this is the code for inject do i use mapping?

[celest notch]

so people would have to enable port forwarding to even use it

[chrome beacon]

yes

but that goes for the server too

[chrome beacon]

So you're not using the mappings

?nms

[chrome beacon]

I had to send you that 4 times for you to read it

[quaint hedge]

oops

sorry

[chrome beacon]

This is why I sigh every time someone tries to make NPCs

It always happens that they ignore advice

[quaint hedge]

no i thought its just a another meaningless message of a bot

i didnt read the message

[chrome beacon]

They all have a meaning

You should at least read it once

[quaint hedge]

you are right

[timid hedge]

How do i use a config path in a switch statement?

Im trying to make a kit plugin with 3 ranks, so if you have add to 1 you will see 1 when you use /kit and if you have 2 you will see 2 and so on..
But i want to make so the ranks name can be changed in the config

[chrome beacon]

So why do you need to switch

[timid hedge]

i though i could switch it because i dont know how i should do it in 'if' statements becuase i think it is going to send the message 3 times if you have alle 3 ranks

[chrome beacon]

That doesn't have to be the case

[timid hedge]

I mean how do i make this on a smarter way?

                if(player.hasPermission(Kits.plugin.getConfig().getString("Vist"))){
                }

                if(player.hasPermission(Kits.plugin.getConfig().getString("Vista"))){
                }

                if(player.hasPermission(Kits.plugin.getConfig().getString("Vist+"))){
                }

[chrome beacon]

New name same old icon ig

[sullen marlin]

make an object for each kit

then make a kit.hasPermission(Player) method

[quaint hedge]

there is a tutorial for Gradle and not maven?

[chrome beacon]

There are unofficial plugins for Gradle

https://github.com/patrick-choe/mojang-spigot-remapper for example

[tender shard]

in gradle I' musing io.github.patrick.remapper, see here for example https://github.com/mfnalex/cesspool/blob/master/nms/versions/v1.20.1/build.gradle.kts#L3

[chrome beacon]

Did you run BuildTools

[tender shard]

*with --remapped flag

[quaint hedge]

code:
plugins {
id 'java'
id("io.github.patrick.remapper") version "1.4.0"
}

group = 'me'
version = '1.0'

repositories {
maven {
url = 'https://hub.spigotmc.org/nexus/content/repositories/snapshots/'

    content {
        includeGroup 'org.bukkit'
        includeGroup 'org.spigotmc'
    }
}
maven { url = 'https://oss.sonatype.org/content/repositories/snapshots' }
maven { url = 'https://oss.sonatype.org/content/repositories/central' }
mavenLocal()
mavenCentral()

}

}
}

compileOnly 'org.spigotmc1.20.4-R0.1-SNAPSHOT:remapped-mojang'
implementation files('D:/Projects Files/Plugins/IdeaProjects/Essential/build/libs/Essential-1.12.jar')
}

and i run the task for remap and i have an error:

Unsupported class file major version 65

my JDK is the problem?

[chrome beacon]

Looks like somethings written in Java 21

[quaint hedge]

ya

should i use in other version?

[chrome beacon]

?

[quaint hedge]

other version of JDK

[chrome beacon]

if you're depending on something written in Java 21 you need a JDK that understands Java 21

so yes

oh and try not to use file dependencies like that

If you only have a jar then install it in to your local maven repo

https://maven.apache.org/guides/mini/guide-3rd-party-jars-local.html

[tender shard]

set your source and target compatibility version to a lower version, like here https://github.com/mfnalex/cesspool/blob/master/buildSrc/src/main/kotlin/cesspool-java-conventions.gradle.kts#L41

[chrome beacon]

^ if you don't plan on using modern Java features

or set it to 17 if you want to be on the same version as 1.20.4

[quaint hedge]

still the same error

[tender shard]

then ?paste the full gradle log pls

[quaint hedge]

oof i HATE NPC

[chrome beacon]

Wait didn't Gradle have problems with Java 21

or is that fixed now?

[tender shard]

idk

[chrome beacon]

alr fixed in Gradle 8.5

so make sure you have that

[quaint hedge]

good point

i will upgrade

[orchid gazelle]

could I theoretically proxy networking so that I can run the main-server on one server but somehow send chunks from another server so that the main-server does not need the bandwidth to upload chunks to the players?

[quaint hedge]

i think i did it. how can i know if its mapped? how do i write the code now?

[chrome beacon]

Methods won't be called a b c anymore

and class names will change

[quaint hedge]

correct

now i dont have PlayerConnection

i have Connection

[tender shard]

net.minecraft.world.entity.monster.Zombie dummy = null;

compile, open with decompiler. If it's remapped, it should say net.minecraft.world.entity.monster.EntityZombie in the decompiled code

[tender shard]

correct

?switchmappings

[undone axle]

https://blog.jeff-media.com/switching-from-spigot-mappings-to-mojang-mappings/

[tender shard]

this explains how to find out the "new" method and class names

[quaint hedge]

niceee

ok i will try now to create the NPC

wait so EntityPlayer doesnt exist now and i dont find the map of it

[chrome beacon]

ServerPlayer

[tender shard]

did you read my blog post?

[quaint hedge]

ya now i reading

wow its very useful

i love it

[tender shard]

because this tells you the name. just do it like explained in the blog post

quilt hashed mappings wtf

[quaint hedge]

i searched like that and it didnt find EntityPlayer

[tender shard]

did you set the search filter to "Spigot"?

[quaint hedge]

oh now i see that thanks

[tender shard]

np

[quaint hedge]

the task of remap still doesnt work
Unsupported class file major version 65

and i use now JDK 11

def targetJavaVersion = 11
java {
def javaVersion = JavaVersion.toVersion(targetJavaVersion)
sourceCompatibility = javaVersion
targetCompatibility = javaVersion
if (JavaVersion.current() < javaVersion) {
toolchain.languageVersion = JavaLanguageVersion.of(targetJavaVersion)
}
}

[chrome beacon]

Use JDK 21

[quaint hedge]

i used that before

[chrome beacon]

or remove the library requiring it

[rough harness]

ok so i made the item but do you know where i can find the id that i would put here

[ivory sleet]

That’s ehm not rly valid

u either go with src compatibility and target compatibility or the toolchain

Idr even if you can use both, but iirc it should give errors

[quaint hedge]

nvm its working the compile but now i have problem when i run it in my server it says it doesnt find ServerPlayer did i forgot something?

[chrome beacon]

That happens when the remapper isn't working

[quaint hedge]

and what could be the problem?

[peak depot]

How can I cancel messages with bungeecord without getting kicked after sending a new message after

[quaint hedge]

something in the compiler?

nvm i see now the remap still have the same error and im using JDK 21

[chrome beacon]

Did you set this to 21

[quaint hedge]

yes

def targetJavaVersion = 21
java {
def javaVersion = JavaVersion.toVersion(targetJavaVersion)
sourceCompatibility = javaVersion
targetCompatibility = javaVersion
if (JavaVersion.current() < javaVersion) {
toolchain.languageVersion = JavaLanguageVersion.of(targetJavaVersion)
}
}

[chrome beacon]

What Gradle version?

[quaint hedge]

8.5

[chrome beacon]

then

Guess it's Gradle being jank again

[ivory sleet]

still, pretty sure you just go with the toolchain?

[quaint hedge]

what is that?

[chrome beacon]

Toolchain is less than ideal

[ivory sleet]

Yeah but the other target compatibility and source compatibility is deprecated afaik

[quaint hedge]

plugins {
id 'java'
id("io.github.patrick.remapper") version("1.4.0")
}

group = 'me'
version = '1.0'

repositories {
maven {
url = 'https://hub.spigotmc.org/nexus/content/repositories/snapshots/'

    content {
        includeGroup 'org.bukkit'
        includeGroup 'org.spigotmc'
    }
}

}

}
}

}

def targetJavaVersion = 21
java {
def javaVersion = JavaVersion.toVersion(targetJavaVersion)

targetCompatibility = javaVersion
if (JavaVersion.current() < javaVersion) {
toolchain.languageVersion = JavaLanguageVersion.of(targetJavaVersion)

}
}

processResources {
def props = [version: version]
inputs.properties props
filteringCharset 'UTF-8'
filesMatching('plugin.yml') {
expand props
}
}

[ivory sleet]

and using both def isn’t the intention behind the design

[quaint hedge]

this is the full code

[chrome beacon]

Guess that's another reason to stick with maven

[ivory sleet]

well whats wrong with toolchain?

[chrome beacon]

It forces the compiler to use a certain Java version

Which means you can't depend on Spigot nms with a Java 8 plugin

[ivory sleet]

I mean I’m pretty sure you can with some fiddling around the toolchain

[quaint hedge]

there is something wrong?

[chrome beacon]

Yeah actually looking at it again

You didn't follow the instructions of the remapping plugin

[quaint hedge]

i will see again

[ivory sleet]

For instance olivo, its possible to set the compiler on certain tasks if you need to override it (like specify java version etc)

[chrome beacon]

hm? could you send the docs for that

[chrome beacon]

Make sure you run the remap task or make build depend on it

[ivory sleet]

https://docs.gradle.org/current/userguide/toolchains.html

[quaint hedge]

thats what im tring to do

i run the remap first

and then i get the error

[chrome beacon]

ignore me then ig

[quaint hedge]

i dont understand what did i miss
i add the remap
i build the buildtools with remap

[chrome beacon]

I don't see how to use Java 17 JDK and compile with Java 8 target?

[quaint hedge]

i did like him

[chrome beacon]

Gradle always breaks for me so idk

[ivory sleet]

java.toolchain.languageVersion.set(… 17 )

someCompilerTask {

javaCompiler = javaToolchains.compilerFor {
    languageVersion = JavaLanguageVersion.of(8)
}

}

According to docs

[chrome beacon]

Wouldn't that force it to use Java 8 JDK for compiling

[ivory sleet]

Yeah they deprecate and change their api so quickly through all the versions

[ivory sleet]

Isn’t that what u wanted?

[chrome beacon]

which would break it depending on a Java 17 lib

[ivory sleet]

.

[chrome beacon]

Needs to be a Java 17 JDK so it can reference the lib correctly

[ivory sleet]

if you shade that lib, then I’d assume maybe

[proud badge]

Do you guys think logging left and right clicks in a database (including the player's held item) is gonna take up lots of storage? The reason is CoreProtect logs a lot of stuff, but it doesnt log everything. I plan on making a plugin that logs things that coreprotect doesnt.

[ivory sleet]

I mean you have compile time dependence and runtime dependence

Which both break differently depending on what u do wrongly

[chrome beacon]

Yeah the compiler doesn't like you referencing a class written in a newer java version

[ivory sleet]

Isn’t the ABI conserved?

[chrome beacon]

ABI?

[ivory sleet]

Application binary interface, yk the binary compatibility

[chrome beacon]

No I don't think so

but I could be wrong

[ivory sleet]

Cuz I know I’ve been doing fine with compiling down to lower versions while depending on libs with higher java versions

So it should be possible, well unless gradle broke recently

[ivory sleet]

same im unsure

[chrome beacon]

With a JDK higher or equal to the lib that's fine

[ivory sleet]

I could see this happening if you shade the lib

Maybe its possible to manage with for instance shadowJar (tho in their case they don’t really have a use for shadowJar presumably)

[chrome beacon]

[ivory sleet]

Gradle is gradle after all 🥲

[chrome beacon]

[wet breach]

If some were smart they would do a runtime compile

[ivory sleet]

Yeah but maybe gradle or whatever thing on gradle fallbacks on the other option :>

[wet breach]

Well runtime compiling is something you have to implement yourself. Not sure if newer jdk versions have this yet

Basically you keep the sources that are version dependent in a separate jar or archive and compile at runtime for the version being used

Since jre and jdk are no longer separate this is more doable then previously

[proud badge]

In the "aliases" part of my command in my plugin.yml do I need to include the /?

[eternal oxide]

no

[proud badge]

    public void onEnable() {
        getLogger().info("A");
    }``` Is this correct?

or do I need to use getPlugin().getLogger() instead?

[young knoll]

That’s fine

[lean pumice]

?paste

[undone axle]

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

[lean pumice]

https://paste.md-5.net/aqehomutuw.sql because this error?

[proud badge]

ok and if I want to use it in an external class? I cant seem to be able to use it in a static context

[young knoll]

?di

[undone axle]

Guide to dependency injection: https://www.spigotmc.org/wiki/using-dependency-injection/

[young knoll]

Or just make a static variable for it

It’s just the logger

[lean pumice]

Beacuse dont resolve dependencies?

i have resolved

[proud badge]

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

Is there an event for when a player throws an ender pearl?

And how could I determine if it was an ender pearl? I see there is a getEntity but is this for the player who launched it or the projectile itself?
