[mystic tundra]

ok

I'm using Eclipse

so it should be in the Eclipes marketplace?

[eternal oxide]

no

sec

[hardy swan]

if your dependencies are other plugins, chances are you dun have to shade anything too, because they should also be present in runtime

[mystic tundra]

I have jsoup

[hardy swan]

you just have to include it in the plugins sections in pom.xml

[mystic tundra]

ah

[hardy swan]

ah ok

[eternal oxide]

?paste

[undone axle]

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

[mystic tundra]

yeah I used other plugins once as well

what should I paste there?

[hardy swan]

he is pasting in it for you to refer

[mystic tundra]

ah

[eternal oxide]

something like https://paste.md-5.net/yuxadamizi.js

[mystic tundra]

oh ok

and then that automatically includes all dependencies?

[eternal oxide]

well almost, remove the comment junk on line 15

[mystic tundra]

yeah

I have another plugin ther

maven-compiler plugin

[eternal oxide]

yep

[mystic tundra]

that's fine?

[eternal oxide]

just add the shade section into your existing plugins section

[hardy swan]

yea it is supposed to be there

if you use maven to build of course

[mystic tundra]

and the indents are fine?

yep

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

I have them like this

[grave kite]

How do I check if a bed was clicked? This code doesn't work

[eternal oxide]

you can fix all indents with CTRL+A then CTRL+I

[mystic tundra]

oh thx

[hardy swan]

or a formatter to format on save 😎

[mystic tundra]

and now I just run the build configuration?

[hybrid spoke]

first: why EventPriority low? second: i am pretty sure its just Material#BED

[mystic tundra]

true but that'd be complicated 🙂 im a beginner

eh now I have two exported jars

ima just re-run it

yeah there's an original- file and then the normal one

[eternal oxide]

one will be a minimized jar, so no dependencies

[mystic tundra]

oh ok

[eternal oxide]

teh larger one will have your depends

[mystic tundra]

kk

[grave kite]

I don't think event priority is that important.
Material#BED or Material_BED don't work

[mystic tundra]

it's 20mb

isn't that too big?

[eternal oxide]

probably

open it up and see whats in it

[hybrid spoke]

Class#Method is JavaDocs. Its Material.BED

[eternal oxide]

default is to shade everything you didn;t set to provided

[mystic tundra]

oh ok

how do I set it to not shade the spigot.jar

[eternal oxide]

add a configuration section...

[grave kite]

there are beds with different colors, but there is no bed type for all colors

[mystic tundra]

yeah the jsoup is there

[mystic tundra]

a new one or add to the original one?

[radiant aspen]

event.getBlock().getBlockData() instanceof Bed

?

[eternal oxide]

probably something like https://paste.md-5.net/oqowakedux.xml

[mystic tundra]

oh ok

[eternal oxide]

add that in the shade plugin section

[mystic tundra]

hey that's better

420kb

[eternal oxide]

open it and make sure it included jsoup

[mystic tundra]

ok

uh I'm about to freak out like a 9 y/o (i'm 14)

[grave kite]

I got

java.lang.NoSuchMethodError: org.bukkit.block.Block.getBlockData()Lorg/bukkit/block/data/BlockData;

[mystic tundra]

it did and my plugin works

it gave me a bald head

[eternal oxide]

nice

[mystic tundra]

theres another problem with the rendering tho

hold on

I'm a mac user

how do I screenshot on windows?

[eternal oxide]

you have to verify on here to upload SS

!verify

[mystic tundra]

is there a way to change my forums username

[hybrid spoke]

donating

[mystic tundra]

the website is glitched

something like that

[undone axle]

Could not find your SpigotMC.org account!

[undone axle]

This account is already verified!

[mystic tundra]

right it's on my deleted account

I forgot

discord deleted my old acc for no reason

it was also Simo

what do I do

[eternal oxide]

Probably contact a mod

[radiant aspen]

sure

[mystic tundra]

I know

[radiant aspen]

Because discord 100% deletes accounts because they are bored

[mystic tundra]

I have no way to prove it

no the minimum age here where I am is 14

and when I was 13 I entered that I'm 13

and it banned it

[eternal oxide]

Contact a mod and you'll need to prove to them you are teh account holder

[tiny wolf]

https://paste.md-5.net/avejaziwof.cpp I get this error, I followed a guide to send an sign, not sure why it happens

It still fully works just sends the error once in a while

[radiant aspen]

just spam ping md a bunch of times, im sure he will fix it

[eternal oxide]

I'd probably ping steel.

[mystic tundra]

ok

[eternal oxide]

as I've no clue how to go about fixing it

[mystic tundra]

I actually started making a plugin for someone

he might be able to vouch idk

he's a server booster rn

[eternal oxide]

you'll probably only need to log in to yoru forum account to prove it

[mystic tundra]

yeah the website is glitched rn

[supple elk]

Can I cast from EntityPlayer to OfflinePlayer?

[mystic tundra]

oh no it's not

[eternal oxide]

EntityPlayer is nms?

[supple elk]

yes

[eternal oxide]

in which case, no

[mystic tundra]

lol 65 alerts on my account

[supple elk]

anyway to convert then?

I want to add my fake EntityPlayer to a team

[mystic tundra]

ehm

To verify your discord account, please click this link.
Note that this cannot be undone

oopsie

[supple elk]

tab list can be order by teams

[runic mango]

q:

where should I put a Random generator?
putting it in onCommand doesn't seem right but intellij doesn't like it being in onEnable

[eternal oxide]

If its a fake player you will add them by name

[supple elk]

what if i have multiple fake players with the same name?

I want to add serveral fake players with no name to the scoreboard

[eternal oxide]

good luck? Entities are added by UUID, Players are added by name

well UUID.toString

[supple elk]

there's a deprecated function to add a Player

[mystic tundra]

how do I check if my args[1] of my plugin command is a player's username?

[eternal oxide]

try adding by name and see what happens

[supple elk]

can I not just get the UUID of my fake player?

a player is an entity right so can I not add it by UUID?

[eternal oxide]

do you really mean args[1] or [0]?

[mystic tundra]

actually args 0

[eternal oxide]

ok, is the player going ot be online?

[supple elk]

it's a fake player I've made, which I've not spawned in for the sole purpose of displaying on tab

[mystic tundra]

yes but I think I have it

for(Player p : Bukkit.getOnlinePlayers()) {
                if(args[0] == p.getDisplayName()) {

[supple elk]

oh

[mystic tundra]

I just had args[1]

[supple elk]

sorry thought u were talking to me with the player stuff

[eternal oxide]

use .equalsIgnoreCase not ==

[mystic tundra]

oh ok

[eternal oxide]

You can try both, one may work

[supple elk]

k I'll try this

[eternal oxide]

If its a fake player you may be limited to adding by name

[supple elk]

they still have UUIDs

[eternal oxide]

It seems to only match on name for Player entities

all non Plyer entities is uses teh uuid

[mystic tundra]

how do I get the star symbol? if I want to do something to everyone, like /smite *

[eternal oxide]

not sure what you mean

[mystic tundra]

like in essentials you can do /smite * and it smites everyone

how do I get the input of *

[eternal oxide]

ah, * is a special character in essentials

it literally looks for it then loops all players and kills them

[supple elk]

it looks like it works?

[mystic tundra]

ah ok

[supple elk]

but for some reason it causes a tonne of lag

[eternal oxide]

so if (args[0].equals("*"))

[mystic tundra]

oh ok

[supple elk]

and hasn't changed the order :/

[eternal oxide]

As I said, Teams may not accept them by UUID

[supple elk]

well it looks like it has worked if you look at what got printed

[young knoll]

The order is alphabetical

Based on the color code

[supple elk]

I'm trying to order them using teams

which should overwrite the order of player names

[eternal oxide]

Yes, that only shows you added those UUIDs to the Team

[supple elk]

            team.unregister();
        }

        final OrderCounter counter = new OrderCounter(2);

        for (MCUTeam mcuTeam : teamManager.getTeamsList()) {
            final ChatColor teamColour = mcuTeam.getTeam().getColor();
            final Pair<String, String> skin = ColourMapper.getSkinfromColour(teamColour);
            final EntityPlayer entityPlayer = createFakePlayer(mcuTeam.getDisplayName(), skin.getFirst(), skin.getSecond());

            final Team team = scoreboard.registerNewTeam(counter.nextInt());
            team.addEntry(entityPlayer.getUniqueIDString());

            Bukkit.getLogger().info("" + team.getName());
            Bukkit.getLogger().info("" + team.getEntries());
            Bukkit.getLogger().info("" + team.getPlayers());

            final PacketPlayOutPlayerInfo packet = new PacketPlayOutPlayerInfo(
                    PacketPlayOutPlayerInfo.EnumPlayerInfoAction.ADD_PLAYER,
                    entityPlayer);
            for (Player player : Bukkit.getOnlinePlayers()) {
                ((CraftPlayer) player).getHandle().playerConnection.sendPacket(packet);
            }
        }```

[eternal oxide]

it doesn;t actually mean it recognises those fake players as those UUIDs

[supple elk]

right

how would i test if it's recognised?

[eternal oxide]

add a team prefix

[supple elk]

good idea

not a prefix in sight

[eternal oxide]

now add them by name not UUID

[supple elk]

still nothing

[eternal oxide]

I guess you are fubar then

[supple elk]

fubar?

I'm going to try to add myself to the team

perhaps the team is not displaying on the scoreboard or something?

I don't know if I need to set the scoreboard to display on the tab menu

[eternal oxide]

are you setting these teams on teh Main scoreboard?

[supple elk]

oh

[supple elk]

ah, no

I made my own scoreboard

[eternal oxide]

try it on main

as its the default

getMainScoreboard

[supple elk]

yeah that worked

[eternal oxide]

just remember Teams are persistent java if ((team = scoreboard.getTeam(TEAM_NAME)) == null) team = scoreboard.registerNewTeam(TEAM_NAME);

[supple elk]

oooh and it's ordered them 😄

[supple elk]

yeah which is why I clear them everytime

I unregister it every time

[eternal oxide]

k

[supple elk]

god why is making a good looking scoreboard so complicated

the other issue is that I still want to use teams to stop team killing

so if I want to have a player listed on the scoreboard

I guess I'll have to create a fake player to look like an actual player?

[eternal oxide]

probably

as players can only be in one team

[supple elk]

yep

god this is complicated

[eternal oxide]

You are going to have to completely disconnect players from teh scoreboard

[supple elk]

there's another issue still

and that's how do I actually clear the fake players from the tab menu

I don't know if there's an easy way to reset the tab menu?

and yeah the UUIDs don't work, only the name

meaning I'm gonna have to give them unique names somehow

and then change the display name

[quaint mantle]

Im looking here, someone is using packets to display particles to all players but is it better than doing World#SpawnParticle

[supple elk]

yeah I could set the name as a random UUID

ooooh

I could set the name and the UUID to the same random UUID

so then I can add them by UUID

ah

perhaps not

yes, but would it be unique then?

is there not a chance it could be the same?

[opal juniper]

Well

It increases the chance a bit yes

Can you not use the most and least sig bits

I may not be remembering correctly

[supple elk]

wdym?

[opal juniper]

I forget where the methods are but there is a way of taking the uuid to a string, think it is uuid.most/least significantbits

That may make it send?

Idk

[undone axle]

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

[quaint mantle]

Hello, i'm making skin changer and it doesn't works (Only works in tab-list and no console errors)

Here's my code

what I tried: runTaskLater

[crude hound]

you need to refresh the others players vision

[near crypt]

?jdk

can anyone send me a link to the newest jdk?

[crude hound]

[eternal oxide]

google AdoptOpenJDK

[eternal oxide]

the last time your server crashed it left a file lock

find the lock file and delete it (with the server stopped)

[crude hound]

it's the session.lock?

[quaint mantle]

but I can't see myself

I want to fix that

[crude hound]

I don't really know how to fix that so I think you can use google to search a packet in this style

[quaint mantle]

I already searched a lot so I'm asking for help ._.

people says : hide and visible player(already do), use runTaskLater(already tried)

etc

[hybrid spoke]

so your only issue is, that you are invisible for yourself? @quaint mantle

[idle grotto]

hey guys, I have a project with multiple maven modules that I am upgrading from java 8 to 16, should I implement java modules together with the maven modules?

[quaint mantle]

nop, I'm visible and my skin doesn't applied.

my skin only applied in tab-list

[hybrid spoke]

what if you "load yourself" by teleporting or else?

[torn jewel]

how do servers deal with client communication do they make a new thread for each client or something else

[hybrid spoke]

client communication á custom client?

[quaint mantle]

oh should I teleport?

[torn jewel]

as in how does the server send data to the clients, Block placing ect
Does it make a new thread for each connection

[hybrid spoke]

most likely. idk if its enough if you just teleport him into the same world. you can try it. otherwise create a new world, teleport yourself in and out so the skin will load

[proud basin]

dope but how do I set the server thing up on my pc?

[loud island]

are you going to host the license server on your pc?

[proud basin]

Yeah on my second one

[loud island]

god no

[proud basin]

Why not?

[summer scroll]

bad idea

[loud island]

idk how your license system is made but if I had to guess, any power outage or network outage would mean broken plugins

[hybrid spoke]

never really dealt with it, but i would say it depends. at least if we are talking about minecraft since the connection is already given. you just sent data to the client and back.

[loud island]

and any user would just end up annoyed that the plugin they payed for isn't working

[eternal oxide]

also if you are not careful you could end up getting ddos'd by your own plugin trying to authenticate

[quaint mantle]

1.17.1?

[dusty herald]

yes

[proud basin]

Wouldn't Cloudflare not be strong enough?

[timid kraken]

guys i am trying to get an even when player recieves an achievement

[silk mirage]

https://streamable.com/94nkva

When I takeout NBT tagged item, It despawns

what could be the cause and solution?

[timid kraken]

this one isn't the one im looking for this one fires everytime the player does any sort of advancement, if the player unlocked a new crafting recipe, etc.

i want an event for when player gets an achievement like "We need to go deeper" etc

[silk mirage]

shh someone

[torn shuttle]

anyone know off the top of their heads if getHighestBlockAt() gets the highest block out of the chunk or the first available passable block?

[silk mirage]

Just add + 1

smh

[torn shuttle]

i.e. if I did it in the nether would it always give me the height of the nether ceil?

[silk mirage]

oh

[eternal oxide]

if you use it in the nether it will alwasy return the very top

[torn shuttle]

thanks

man I really wish minecraft wouldn't invent negative y coordinates

[opal juniper]

wdym its literally the most intelligent thing ever

[torn shuttle]

mhm

[silk mirage]

hmm

[unreal quartz]

nah they should've done away with the y plane and just have you play on a flat surface

[silk mirage]

Anyone gonna help me?

[idle grotto]

@silk mirage can you reproduce the issue on the latest version?

[silk mirage]

have not tried yet

[torn shuttle]

bruteforcing valid spawn locations feels wrong

[waxen plaza]

I am using a chunk pregeneration plugin to generate chunks and I was wondering if there is a way to make my server use more resources. I am using this java -Xmx4G -jar spigot-1.17.1.jar nogui when launching the server.

[silk mirage]

specficy -Xms for minium resources

use aikari flags

[waxen plaza]

-Xms 4G ?

[silk mirage]

-Xmx4G

[waxen plaza]

I already have that

[silk mirage]

sorry

i meant -Xms4G

[waxen plaza]

oh

ok

btw do I use both? Xms and Xmx

[silk mirage]

yes

[waxen plaza]

ok

[silk mirage]

-Xmx is maxium ram

[waxen plaza]

ok

[supple elk]

how do I make an IChatTextComponent?

I tried this

[lusty cipher]

which one of these is better (i know, it doesn't really matter, just wondering)?

T[] values = x;
for (int i = 0; i < values.length; i++) {
  T value = values[i];
  if (value == null) continue;
  if (value.something()) return i;
}

T[] values = x;
for (int i = 0; i < values.length; i++) {
  if (values[i] == null) continue;
  if (values[i].something()) return i;
}

[dusk flicker]

not really a difference, personally id use the first one but its basically preference at this point

[lusty cipher]

I mean the second one is 2 array lookups so it's probably a little slower

[dusk flicker]

doubt thats a speed decrease you would notice

[minor garnet]

aah gentlemen, can someone please specify my problem

[summer scroll]

TextComponent.fromLegacyText maybe?

[supple elk]

this has done what I needed it to

[foggy bough]

quick question... does this code check if the button is right clicked? ```java
public void onInteract(PlayerInteractEvent e) {
Player player = e.getPlayer();
ItemStack block = new ItemStack(Material.ACACIA_BUTTON);
player.getInventory().addItem(block);
if(player.getMainHand().equals(block)) {

    }```

[stone sinew]

no

[supple elk]

it gives them a button on an interact event

[stone sinew]

You aren't even checking the type of the block clicked

[foggy bough]

how to do that?

[supple elk]

have a look what comes up when you do e.

.getClickedBlock()

[foggy bough]

ok

[supple elk]

then check if that block is a button

[foggy bough]

ok so like this? ```java
public void onInteract(PlayerInteractEvent e) {
Player player = e.getPlayer();
ItemStack block = new ItemStack(Material.ACACIA_BUTTON);
player.getInventory().addItem(block);
if(e.getClickedBlock() == block) {

    } else {
        return;
    }
}```

uhhhhhhhhhhhhhhhh what is your question?

[maiden briar]

Why does this not work?

[summer scroll]

not even close

[maiden briar]

Oh my foult, I specified the directory 2 times...

[summer scroll]

getClickedBlock will return Block iirc.

[foggy bough]

???? so how can I fix this?

[chrome beacon]

You forgot to remove your user name in the second path

[maiden briar]

Yes I understand

Thx

[summer scroll]

Compare the material

[foggy bough]

how? With what method? pls be specific

[supple elk]

blocks are positions in the world

so you need to do e.getClickedBlock().getMaterial() == Material.ACACIA_BUTTON

[foggy bough]

the button will be in my hand

[supple elk]

why do you want the button in your hand?

oh

[foggy bough]

it is in my hand

[supple elk]

are you trying to test if they right click a button in their hand?

[supple elk]

do you want the button to be in your hand

[foggy bough]

yes

[supple elk]

ok

[foggy bough]

yes

[supple elk]

so you're not trying to test if they right click a button in the physical world

[foggy bough]

yes

[supple elk]

right in which case you ahve the wrong event

[foggy bough]

dang

[supple elk]

I think

[foggy bough]

it

[supple elk]

actually maybe you don't

lemme check

no I think you have the right one

in which case you want to compare player.getItem().getMaterial() to Material.ACACIA_BUTTON

or whatever it is

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

the docs for the event might help you

[summer scroll]

event.getItem() to get the item in hand

[foggy bough]

I have been trying to get what is in the players Main hand but all it gives me is the deprecated method

[supple elk]

oh yeah, event.getItem()

[foggy bough]

ok

[supple elk]

that's because there are hands now

so you get inventory first

then you can get the item in either hand

but the event already has a method for the same thing so you may as well use that

[foggy bough]

oh thats what I was doing wrong

[summer scroll]

woah, nice theme - like that a lot

[foggy bough]

yeah lol

[supple elk]

ty, I spent a while customising it

I based it off of the darkest dark theme in eclipse

[foggy bough]

ok well thx

[supple elk]

my whole IntelliJ looks dope

[supple elk]

np

[summer scroll]

can i have that lol

[supple elk]

sure, lets go dms

[foggy bough]

would this work? ```java
if(e.getItem() == block || player.getInventory().getItemInMainHand() == block) {

    }```

or should I just keep the e.getItem

[supple elk]

why are you comparing it to the block?

[foggy bough]

OHHHHHHHHHHHHHH

I AM DUMB

YOU SEE

[supple elk]

e.getItem().getMaterial() == Material.ACACIA_BUTTON

[supple elk]

lol

[foggy bough]

3IQ

[supple elk]

xd

the block is in the physical world

and you need to compare materials

[hybrid spoke]

just do it within a millisecond. teleport to and back. thats the way to go

[quaint mantle]

ah thanks u!

[wild vault]

hey so im trying to do a basic plugin that multiplies diamond drops, but nothing ive found works

does anyone know the code for the drop multiplier?

[chrome beacon]

Do you know Java?

[wild vault]

a little, im still a beginner but i have experience

[chrome beacon]

Alright so what you can do is just use a Datapack instead of a plugin. If you do want to use a plugin listen to the BlockBreakEvent and set the drops in #getDrops

?eventapi

[undone axle]

https://www.spigotmc.org/wiki/using-the-event-api/

[chrome beacon]

Here's the guide on how to work with events

[wild vault]

thanks, ill try it 🙂

[supple elk]

is there a way I can get a list off all players being displayed to somebody?

currently I'm doing this to add fake players to the tab menu

[hybrid spoke]

are those all errors or is it your theme?

[supple elk]

theme

[hybrid spoke]

ugh

[supple elk]

you don't like my theme :?

[hybrid spoke]

no

[supple elk]

angee

[chrome beacon]

Red is for errors :kekw:

[supple elk]

is good theme D-:<<<

underlining is for errors

anyway back to the question

I can add players like this

[hybrid spoke]

themes with red colors for anything else than errors are a bad habit

[supple elk]

but I have no idea how to track them

they persist across reloads

[hybrid spoke]

store them

[supple elk]

they don't show up in Bukkit.getOnlinePlayers()

[hybrid spoke]

yeah obv.

[supple elk]

so just store them as I add them?

[hybrid spoke]

ya

[supple elk]

then send a packet to remove each one?

[hybrid spoke]

yup

[supple elk]

ok that's not gonna fly across reloads but if that's the only option then so be it

I find it weird how there isn't like a packet to just reset the tab menu

[eternal oxide]

you can store their data in the spawn chunk PDC so you know what fake players exist

[supple elk]

too complicated for it's worth

doesn't really matter as server shouldn't be reloaded in normal use

[hybrid spoke]

using a PDC would be the way to go if you wanna have it persist a reload

[hybrid spoke]

^

just remove them when disabling

and add them again on enable

[supple elk]

oh that's a good idea

[hybrid spoke]

then you have it "persistent"

[supple elk]

big brained man

[opal juniper]

out of interest @supple elk what are they for?

[supple elk]

the fake players?

[opal juniper]

yeah

[supple elk]

making a tab menu

[opal juniper]

ok

[supple elk]

it's how hypixel does it

well, I assume that's what they must do

[proud basin]

will keep that in mind

[supple elk]

I wish customising it was easier imo

[sturdy patrol]

mmmh

Is there no other way to do a custom tab?

You you really have to create fake players? 🤔

[supple elk]

yup

or if there is another way, I haven't found any mention of it

Hypixel is doing it, so I doubt there's a better way

[quaint mantle]

How can I refresh someone's skin without NMS? I'm changing their skin in their gameprofile which is fine, except it's not updated on the player's own screen

[mystic tundra]

    public final void reloadSkinForSelf(Player player) {
        final EntityPlayer ep = ((CraftPlayer) player).getHandle();
        final PacketPlayOutPlayerInfo removeInfo = new PacketPlayOutPlayerInfo(EnumPlayerInfoAction.REMOVE_PLAYER, ep);
        final PacketPlayOutEntityDestroy removeEntity = new PacketPlayOutEntityDestroy(new int[] { player.getEntityId() });
        final PacketPlayOutNamedEntitySpawn addNamed = new PacketPlayOutNamedEntitySpawn(ep);
        final PacketPlayOutPlayerInfo addInfo = new PacketPlayOutPlayerInfo(EnumPlayerInfoAction.ADD_PLAYER, ep);
        final PacketPlayOutRespawn respawn = new PacketPlayOutRespawn(ep.dimension, ep.getWorld().getDifficulty(), ep.getWorld().getWorldData().getType(), ep.playerInteractManager.getGameMode());
        ep.playerConnection.sendPacket(removeInfo);
        ep.playerConnection.sendPacket(removeEntity);
        ep.playerConnection.sendPacket(addNamed);
        ep.playerConnection.sendPacket(addInfo);
        ep.playerConnection.sendPacket(respawn);
        player.updateInventory();
    }

thats what I use

could you try it out? Whenever I use this everything around me loses it's texture and becomes transparent for quite a long time

I wanna know if it's my computer's fault or the code's

@quaint mantle

[quaint mantle]

that uses NMS

[sturdy patrol]

For up to 1.16 you could try using this api: "https://www.spigotmc.org/resources/tablist-1-12-1-16.78073/"
For 1.17 I have not found anything but you could try looking into this plugin (source available on github): "https://www.spigotmc.org/resources/animated-tab-tablist.46229/"

[supple elk]

nah I don't wanna use an API

thx for the links tho

[paper viper]

Bro you leaked an IP address lmao

[tiny wolf]

so ?

[ivory sleet]

Against the rules

[tiny wolf]

oh lol

sorry

Its my dbs Ip

Ill remove it and resend it

found unexpected end of stream
 in 'string', line 11, column 1:
    
    ^```

is basically what it says, but why would it error..

[supple elk]

how do I copy across my mask?

It's actually a fake player in the second screenshot

I copy both skin texture and signature

[mystic tundra]

It might also work to teleport him far away and back, though im not sure

[wild inlet]

java.lang.NullPointerException: Cannot invoke "String.length()" because "<parameter1>" is null```

Getting this error compiling a pretty basic project with maven

Anyone any idea why?

[eternal oxide]

"String.length()" because "<parameter1>" is null

[wild inlet]

Yeah I got that part

But it's not really something I know how to solve

[eternal oxide]

so where are you using .length()?

[wild inlet]

Yeah that's not the issue

[eternal oxide]

yes it is

[wild inlet]

Then you have no idea what you're talking about

as I don't use it in that project at all 🙂

Probably to do with JDK setup

[quaint mantle]

if you're talking about the 2nd layer of the skin, you need to edit the npc's datawatcher and set index 17 to 127 to enable it

https://wiki.vg/Entity_metadata#Player

there's more info in that table

[wild inlet]

Building against Java 8 fixed this

[minor garnet]

public void drawLine(final Location start, final Location end, final double space, final boolean third) {
        final double distance = start.distance(end);
        World world = start.getWorld();
        Vector point1 = start.toVector();
        Vector point2 = end.toVector();
        Vector vector = point2.clone().subtract(point1).normalize().multiply(space);
        List<Player> list = new ArrayList<>();
        
        if (third) world.getPlayers().stream().filter(all -> !all.equals(player)).forEach(all -> list.add(all));
        else list.add(player);
        
        for (double length = 0; length < distance; point1.add(vector)) {
            list.forEach(all -> {
                all.spawnParticle(Particle.CRIT, point1.getX(), point1.getY(), point1.getZ(), 0);
            });
            length += space;
        }
    }```
so, I am wanting to make a line of particles from point a to b, but I would need to make these particles visible only to all players except a specific player, the problem is that the lines of particles are appearing in a line, it only starts at the beginning and ends at the end, does anyone know why ?

[granite stirrup]

no there is other ways to make a custom playerlist

https://bukkit.org/threads/custom-player-lists-create-your-own-tab-list-display.429333/ i saw this rn but idk if it works or not

its probs for a older version of minecraft tho

[last harbor]

I'm trying to compile a class...

ToolProvider.getSystemJavaCompiler().getTask(null, manager, null, Arrays.asList("-classpath", "spigot.yml:plugins/PlaceholderAPI.jar"), null, cl)```
I can only use the objects from spigot.jar in that class, but I can't find a way to acces PlaceholderAPI.jar too
Does anyone know how can I do that?

[granite stirrup]

just randomly found it tho

[granite stirrup]

?

if your trying to do things with PlaceholderAPI use its api

[last harbor]

I want to acces the classes from that jar file from the compiled class

[granite stirrup]

why

[last harbor]

because I need to?

[granite stirrup]

for what

just use the api?

[last harbor]

.-.

ToolProvider.getSystemJavaCompiler().getTask(null, manager, null, Arrays.asList("-classpath", "spigot.yml:plugins/ArandomSpigotPlugin.jar"), null, cl)

[granite stirrup]

https://github.com/PlaceholderAPI/PlaceholderAPI/wiki

that tells you how to use the api

for placeholderapi

[last harbor]

that's not what I need

[granite stirrup]

WHy

you havent telled me why you want to access the classes in the jar

[winged ridge]

Hello, I'm having an issue when I try to find a UUID converted to a string in a List.
https://pastebin.com/HLWXnMhr

1. So I have UUID uuid = p.getUniqueId(); which gets the player UUID
2. I then convert it to a string using String uuidStr = uuid.toString();
3. Then check it was converted properly with System.out.println(uuidStr); (yes it was)
4. And finally checks if the uuidStr is in the List players with if (e.getAction() == Action.RIGHT_CLICK_BLOCK && !players.contains(uuidStr)) {}
5. But when II click a block I get the error in the link above

[stone sinew]

Need the code.

[chrome beacon]

And what's the error

[winged ridge]

the pastebin link

[stone sinew]

line 67 is null

[granite stirrup]

code?

[chrome beacon]

Well then what does it say is null

I'd assume players is

[winged ridge]

String uuidStr = uuid.toString();
System.out.println(uuidStr);


if (e.getAction() == Action.RIGHT_CLICK_BLOCK && !players.contains(uuidStr)) {```

[chrome beacon]

Is players null

[granite stirrup]

give all the code ?

[winged ridge]

no

[eternal oxide]

ChestListener.java:67

[winged ridge]

line 67 is the if

[winged ridge]

ok

[eternal oxide]

players is null as others have said

[granite stirrup]

players is defiantly null then

[winged ridge]

I can try printing players

[granite stirrup]

do you initialize the array list?

[winged ridge]

oh it is null in fact

[chrome beacon]

Mhm

[granite stirrup]

List<String> players = new ArrayList<>();

[winged ridge]

but then how can I check if the uuid is or is not in players, if it gives me an error

[eternal oxide]

what is players supposed to contain?

[winged ridge]

UUIDS

[eternal oxide]

uuids of what?

[chrome beacon]

Well you can't check if something is in a list that doesn't exist

[winged ridge]

of player sthat click a chest

[chrome beacon]

So start by creating that list

[granite stirrup]

List<String> players = new ArrayList<>();

[eternal oxide]

and where are you putting those players IN the players list?

[winged ridge]

https://pastebin.com/T5NByxE7

[granite stirrup]

dont set it to null

[granite stirrup]

do this

[eternal oxide]

ok, I'm backing out of this one

[winged ridge]

it supposed to serialize it a json and then deserialize it

[winged ridge]

ok

[eternal oxide]

players is null, reader is null

[winged ridge]

but wait I should set UUID instead of String

[chrome beacon]

Just replace String with UUID

[earnest sonnet]

Yes

[granite stirrup]

are you storing the uuid as string?

[earnest sonnet]

I hope nope

[winged ridge]

I'm storing it in a list as UUID

[granite stirrup]

wouldnt it be a string tho in the json file

pretty sure also theres UUID.fromString(String str)

[eternal oxide]

ok, your path is wrong for reading yoru json

/home/yot/Documents/Java/MasterSword/src/com/yot/mastersword/players.json

[winged ridge]

why?

[eternal oxide]

thats not going to resolve from the Spigot plugins folder

[earnest sonnet]

Yes, but depending what you're doing it having it as UUID can boost the performance a dat bit

[winged ridge]

its a personal plugin for now

and it does recognize the json

[eternal oxide]

its still nto going to resolve when teh base directory is the server

[granite stirrup]

pretty sure its this yourPlugin.getDataFolder().toString() + "/players.json"

if you have it in your data folder for your plugin

[granite stirrup]

so what

your gonna have to store it as a string anyway in the json

atleast i dont think you can store objects in json

[earnest sonnet]

Does a JsonElement count as an object ?

[winged ridge]

If I cut the code to the if statement it works fine

it does print all uuids

[pulsar zenith]

hey is it possible to make it possible to somehow hit through a player?

[granite stirrup]

tho if you stored a object in there it wouldnt look that nice in the file

and also it would be uneditable

[earnest sonnet]

Yes with maths or if you have access to collision shapes

As for how with maths, I can't help you xD sorry

[winged ridge]

Everything works if I check if the UUID is in the players List, but if I check if it isn't in the players List, it does not work

[granite stirrup]

¯_(ツ)_/¯

[urban lava]

when creating the first eclipse project does the name and description matter

[ivory sleet]

uh not really

you can always change it later anyway

[sharp bough]

could someone tell me a way to make this code cleaner? https://paste.md-5.net/avusemihat.cs i reallly dont like this part of my code, class: https://paste.md-5.net/ifukusuhuf.java

[dusk flicker]

This looks like a utility, so you shouldent be creating a new instance of it and thus should be static https://cdn.rackdevelopment.tech/img/PaMDKVIPya.png

[sharp bough]

    public boolean senderIsPlayer(CommandSender sender){
        if(!(sender instanceof Player)){
            sender.sendMessage("You cant run this command on console");
            return true;
        }
        return false;
    }
}```
its just that, but i plan on adding a few more things when the sender is not player

so they cun run a few commands from console

[ivory sleet]

• private final whenever possible
• implicit else
• try to pull out logic into functions for composition and possibly re-usability.
• also your kitmanager, why create new instances of it all the time?

[sharp bough]

doesnt the final thing delete the variable after the code runs?

[ivory sleet]

thats not true

it does for local variables

not for instance variables/fields, nor methods, nor classes

[final fog]

PotionMeta potion = (PotionMeta) player.getEquipment().getItemInMainHand().getItemMeta();
System.out.println(potion.getColor());``` Is this how you do PotionMeta, because getColor() returns null for me.

[sharp bough]

https://paste.md-5.net/gumimevuro.java is this better?

[final fog]

getBlockX()

[final fog]

Still looking for some more info on this any help is appreciated

[proud basin]

I seem to be getting a null pointer at this line eco.bankDeposit(killer.getName(), 5); even though eco isn't null and killer isn't null

[ivory sleet]

name is null perhaps

[proud basin]

hm

I don't see why it would be null though

[dusk flicker]

the stacktrace would tell you everything

[smoky oak]

How can i get a baked in config file? It isn't supposed to be changed, so I don't need to write it to disk, but getConfig() only seems to work for the default config.yml that way?

[torn shuttle]

is the negative y level here to stay or is it a placeholder while we don't have pt 2 of 1.17 aka 1.18?

[smoky oak]

considering it will come in 1.18 i doubt it'll vanish

[proud basin]

?paste

[undone axle]

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

[torn shuttle]

I had doubts they would make negative y values to start with yet here we are

it's just I'm currently working on starting a multi-month long build project for which I need to make specific world painting plugins and it would suck to start only to have 1.18 show up in 6 months and wipe it clean

[final fog]

PotionMeta potion = (PotionMeta) player.getEquipment().getItemInMainHand().getItemMeta();
System.out.println(potion.getColor());```

Is this how you do potionmeta, because the getColor() is returning null.

[eternal night]

Afaik colour only returns something when a custom colour is applied

Default potion colours through potion effect types may not Return their colour there

[final fog]

that's probably whats going on

So is it completely impossible to get the default potion color?

Or is there another way I could do this

[eternal night]

I don't know of a place where the server tracks them sadly

But that's just my knowledge

[final fog]

Ah, alright. Thank you.

[proud basin]

Nope it's not

[eternal night]

Would greatly benefit from those java 15 npe messages

[proud basin]

• https://paste.md-5.net/qabijiyadu.cs

whats on that line

exactly

[proud basin]

.

I've already provided it

[dusk flicker]

How are you telling if they are not null

[ivory sleet]

I wonder that too

[proud basin]

printing them

[dusk flicker]

Can you send the entire class rather then just the line

[chrome beacon]

You can also use a newer version of Java and it will tell you what's null

[ivory sleet]

I mean it's possible the underlying shit might be badly coded

[lament bronze]

Hey so I'm currently working on a plugin api for my friend and I wanna leave him javadoc or any form of documentation.

All I know atm is that you can package the plugin and use it as a dependency but of course that removes all of my documentation.

Can anyone point me in the right direction?

[ivory sleet]

Do you use gradle?

[lament bronze]

maven

[ivory sleet]

ah sry idk maven that well

[lament bronze]

f

[proud basin]

@EventHandler
    public void KillStats(PlayerDeathEvent e){
        Player killed = e.getEntity().getPlayer();
        Player killer = e.getEntity().getKiller();
        addDeath(killed);
        int randomAmount[] = new int[1];
        if (killer instanceof Player){
            for (int i = 0; i < randomAmount.length; i++) {
                randomAmount[i] = (int) (Math.random() * 30 + 1);

            }
            addKill(killer);

        }
    }

[chrome beacon]

?paste

[undone axle]

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

[lament bronze]

How would you do it in gradle? Maybe its similar with Maven

[dusk flicker]

How are you testing it EXACTLY

How are you triggering the event

[chrome beacon]

I think maven has the Javadoc plugin

[lament bronze]

      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-javadoc-plugin</artifactId>
        <version>3.3.0</version>
        <configuration>
          ...
        </configuration>
      </plugin>

ah

i see

ill try this

[proud basin]

Printing out killer.getName() and setupEconomy(). Testing it by killing another player

[dusk flicker]

Show us setupEconomy

[proud basin]

public boolean setupEconomy() {
        if (getServer().getPluginManager().getPlugin("Vault") == null) {
            return false;
        }
        RegisteredServiceProvider<Economy> rsp = getServer().getServicesManager().getRegistration(Economy.class);
        if (rsp == null) {
            return false;
        }
        econ = rsp.getProvider();
        return econ != null;
    }

returns true

[dusk flicker]

How are you setting 'eco'

[eternal oxide]

You have two economy type variables, econ and eco.

[proud basin]

Economy eco = Core.getInstance().getEconomy();

[dusk flicker]

Stop sending us single lines

[chrome beacon]

And now show us the getEconomy method

[dusk flicker]

send us methods or the entire class

[proud basin]

public Economy getEconomy() {
        return econ;
    }

[dusk flicker]

show us your onEnable

[proud basin]

public void onEnable() {
        instance = this;
        scoreboardManager = new ScoreboardManager(this);

        playerManager = new PlayerManager();
        textActionBar = new TextActionBar();
        kitGui = new KitGui(this);

        registerCommands();
        registerEvents();

        saveDefaultConfig();
        config();
        
        reloadConfig();
        setupEconomy();
        getLogger().info("Setting up economy: " + setupEconomy());

        if (!Bukkit.getOnlinePlayers().isEmpty()) {
            Bukkit.getOnlinePlayers().forEach(player -> {
                playerManager.addPlayer(player.getUniqueId(), new IPlayer(player.getUniqueId()));
            });
        }

        scoreboardManager.runTaskTimer(this, 20, 20);

    }

[chrome beacon]

You're registering events before econ

So your eco variable is null

[proud basin]

You are right

[chrome beacon]

Tip for next time debug the variable you're using and not something else

[nova mirage]

Hi, I've upgraded my servers to 1.17 recently and I can't seem to find net.minecraft.server.v1_17_R1 (or anything similar to that) in the jar file. I used this in 1.16 to send custom packets. Is there any workaround to this?

[dusk flicker]

they removed that

[chrome beacon]

1.17 uses vanilla package names now

[dusk flicker]

wont include v1_17_R1 or anything like that anymore

[nova mirage]

ah

[smoky oak]

InputStream customClassStream = instance.getClass().getResourceAsStream(path);
        InputStreamReader strR = new InputStreamReader(customClassStream);
        return YamlConfiguration.loadConfiguration(strR);```
I'm trying to load the baked in configuration, but I always get a NPE. What does 'path' have to look like if I place a structure_config.yml in src/main/resources, whereas the plugin entry file is in src/main/java/<github path>/<plugin_name> ?

[chrome beacon]

Oh and note that methods are unmapped by default now

[chrome beacon]

Why are you using a stream to load the config?

[smoky oak]

because i dont want to save it to file

*drive

[chrome beacon]

Ah

[smoky oak]

It has to be changed only on my end

I'm making it so that the code is easier to understand but that config file isnt supposed to actually change

[nova mirage]

sorry what does this mean?

[chrome beacon]

Methods are named a() and such in NMS

[nova mirage]

ah

got it, thanks

[chrome beacon]

Read the 1.17 release post for setting up mappings

[eternal oxide]

this.getResource("resourcename") returns an InputStream

[smoky oak]

yes

but what string to put there

because everything i tried got a NPE

[chrome beacon]

Name of file

[eternal oxide]

no need to drill down to the class loader

just the file name

[jagged badge]

I want to detect when the player drops an item in an inventory. I use InventoryAction, except that there are too many possible cases to put an item in the inventory (click, shortcut, 1 item, half, or all etc). So I wanted to know if there is something that detects the action of putting an item in an inventory, no matter how.

thx

[smoky oak]

@eternal oxide same issue.

java.lang.NullPointerException: null
at java.io.Reader.<init>(Reader.java:167) ~[?:?]```

[eternal oxide]

open your jar and see if the file is in there

[chrome beacon]

Also what did you set the string to

[smoky oak]

io
META-INF
config.yml
plugin.yml
structure.yml

structures = getDefaultConfig("structure.yml");
//...
public FileConfiguration getDefaultConfig(String configFile){
        InputStream customClassStream = getClass().getResourceAsStream(configFile);
        InputStreamReader strR = new InputStreamReader(customClassStream);
        return YamlConfiguration.loadConfiguration(strR);
    }

All that in main plugin class

and the file is there

[chrome beacon]

Just use getResource like ElgarL said

[smoky oak]

I did

it got worse

org.bukkit.plugin.InvalidDescriptionException: Invalid plugin.yml

@chrome beacon

[dusk flicker]

does the stacktrace send anything else

make sure your main package is correct and the class name is correct

[smoky oak]

that it is because the rest of it works

also

wait wth

the plugin works

the server is messing up
I'mma excuse myself to #help-server

[nova mirage]

The reason I was using NMS was because I was trying to make invisibility also hide your armor, but I couldn't find any solution that didn't have NMS, so I had to resort to NMS. Player.hidePlayer seems to also hide the player from tablist, so is there any other way I could hide armor?

[zinc yarrow]

Is Player#setPlayerListName meant to only display the list name to oneself? that's the behavior I'm getting and I need everyone's list name to display to everybody else, yet I can't find any docs for it and all setPlayerListName docs says is that it sets the players list name ..

[chrome beacon]

I've done it before with Protocollib. It's not that hard

[lament minnow]

Which version of the Spigot server jar would be best for developing a plugin?

as in, the default, or the remapped-obf, or the remapped-mojang

etc

[nova mirage]

Ah the reason my 1.16 code wasn't working was because the code wasn't mapped, I got it now, thanks for your help!

[lament minnow]

assume that the plugin requires the server jar

i am making a fork of another plugin which makes use of the server jar

but updating to 1.17.1 changed some obfuscations so i want to know which jar would be best to use to make things easier

Hello again, so I have an if statement that checks if a block is touched and then do some things, but it only work once, then I need to reload the plugin for it work again .
the if statement : if (e.getAction() == Action.RIGHT_CLICK_BLOCK) {...}

[quiet ice]

remapped-mojang should be the best for you in terms of binding into it, but outside of that it might be cancer to work with

[lament minnow]

see, this is why i want a guide to convert from nms to spigot-api code

[quiet ice]

The issue is that people use NMS for 20000 reasons

[lament minnow]

if i recall correctly, using the remapped-mojang requires obfuscating the jar, because legal reasons, right

[quiet ice]

Unlikely - why exactly this is done is beyond me

[lament minnow]

oh okay

well that makes things easier so i am fine with that

i did not feel like setting up obfuscation

[quiet ice]

As long as you do not distribute that jar you should be fine

In almost all occasions that I have seen usage of NMS I was unable to find a 100% ideal solution that did not use bukkit api or protocollib

You have to make compromises when converting code, which I would only do on a case by case basis

but if you have any questions on how to convert something, feel free to ask; someone should be able to find a solution

[urban lava]

how do i fill out this

to match to what im supossed to do here

[lament minnow]

you could just do it manually

[urban lava]

how

[lament minnow]

typing in the java file

[urban lava]

i cant type in it tho

its a package thing

[ivory sleet]

Fill the mandatory name field

[lament minnow]

just name the file, create it, and then type

or copy and paste, to make it easier

[lament minnow]

and make the name of the class the same as the name of the file

what is the issue

[ivory sleet]

....

[urban lava]

ok

thanks

sorry i haent done much with java i just used online compilers for the basics

should the name be like the io.github thing

ohwait

[ivory sleet]

No

[urban lava]

nvm

artifact

[ivory sleet]

Read on Java naming specifications

[lament minnow]

yes, NAMING CONVENTIONS

blessed

[ivory sleet]

Remove the curly brackets around RandomPotionPlugin

https://www.spigotmc.org/wiki/creating-a-blank-spigot-plugin-in-eclipse/

[lament minnow]

i would recommend intellij idea, but you do not know how to use java, and i doubt that you know how to use maven, so you can stick with eclipse

[ivory sleet]

IDE is totally irrelevant

[lament minnow]

yeah

just recommendations

[ivory sleet]

Still

Won’t help him in this very case

[lament minnow]

good point

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

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

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

[urban lava]

its jsut the bukkit fandom tutorial says to use eclipse so i went with thta

im just tryna make a basic plugin

datapacks are easier but way more limiting

[ivory sleet]

Correct

[lament minnow]

and also inefficient when multiple are used, according to my plugin-developing friend

though they can easily implement things like advancements and worldgen

unfortunately, i do not think that any plugin exists for eclipse or intellij which allows for easier creation of data/resource packs

so that sucks

Anyone know what PacketPlayOutNamedEntitySpawn's remapped name is? I am thinking either ClientboundAddEntityPack, ClientboundEntityEventPacket, or DebugEntityNameGenerator.

[pseudo raptor]

guys, how do I make that when a player who is in an ArrayList disconnects, its inventory is cleared?

[lament minnow]

A Spigot event exists for logging off, I believe.

You could make an EventHandler for that event, and make it clear the inventory.

[pseudo raptor]

I used PlayerQuitEvent, wouldn't it do?

[lament minnow]

it would

i believe

[pseudo raptor]

So... from the tests I've done, when the player disconnects, he automatically leaves the list, so there's no way to clear his inventory.

[lament minnow]

Oh.

[pseudo raptor]

One second, can I add him to another list when he disconnects?

[lament minnow]

@EventHandler
public void onQuit(PlayerQuitEvent event) {
   // some code for clearing inventory 
}

[tall ridge]

why can't you clear the inventory

[lament minnow]

probably because the player is off

[pseudo raptor]

I just don't know, as I said, apparently the same goes off the list when you disconnect.

[eternal oxide]

the player is not yet disconnected in the event

[pseudo raptor]

I tried to clear the inventory when it re-enters, but it is no longer on the list.

[tall ridge]

you have a list?

[lament minnow]

actually

what if you do it so it clears on join instead

[tall ridge]

either one should work...

[pseudo raptor]

Yes. For ease, imagine that when the player runs / arena, he will enter an arena. I made a list so that the player who enters does not fulfill certain events when present on it.

[tall ridge]

so check your list before you remove the player from it!!!!

[pseudo raptor]

What would be a correct way to use an ArrayList in another class? I may be using a wrong method that may be causing this.

[tall ridge]

how are you doing it now?

I made this example class just to test this out and this clears the player inventory on disconnect for me...public class playerQuit implements Listener{ @EventHandler public void playerLeave(PlayerQuitEvent e) { e.getPlayer().getInventory().clear(); } }

[pseudo raptor]

`` @EventHandler
public void onQuit(PlayerQuitEvent e) {
Player p = e.getPlayer();
String nick = p.getDisplayName();

    if(PNaArena.contains(nick)) {
        e.getPlayer().getInventory().clear();
    }
}``

I'm doing it this way

[tall ridge]

what is PNAArena

PNaArena*

that is your list?

it's in the same class or different class, how is it being referenced?

[pseudo raptor]

is an arraylist with the players that are in the arena. I was testing

[tall ridge]

the list isn't empty?

[pseudo raptor]

is in the same class

[tall ridge]

p.sendMessage("PNaArena.toString()"); prints out what?

[pseudo raptor]

I don't think so, since when the player is already in the arena, he can't get back in, due to the verification I made

[pseudo raptor]

i gonna try

[tall ridge]

or something more like list.toArray().toString() xd

[pseudo raptor]

Okay, now it's no longer removing the player when it disconnects.

However, it's not cleaning up his inventory either.

Hmmmmm, wait

[wild inlet]

I have a plugin depending on a plugin with obfuscated nms, but I only have the remapped version as a dependency. When compiling, I get this error.
Error:(50,17) java: cannot access net.minecraft.nbt.NBTTagCompound

Anyone got any idea how to fix that?

It's trying to access the obfuscated version but apparently it's cant?

[tall ridge]

@pseudo raptor do you wanna show me your list? eg public static List<Schematic> Schematic = new ArrayList<Schematic>();

[proud basin]

Since when did Essentials Eco not support bank accounts?

[tall ridge]

when will people stop throwing their money away

[pseudo raptor]

public ArrayList<String> PNaArena = new ArrayList<String>();

[tall ridge]

and show me where you add players?

I'd make the list static btw

[pseudo raptor]

if(args[0].equalsIgnoreCase("entrar")) {
if(!(PNaArena.contains(p.getDisplayName()))) {
PNaArena.add(p.getDisplayName());

basically this

[proud basin]

uh

why are you storing their name

[pseudo raptor]

wouldn't it be easier?

[tall ridge]

uuid's are the norm

[proud basin]

use UUID

[pseudo raptor]

it was the way they taught me

[tall ridge]

old

[pseudo raptor]

i gonna try

[quaint mantle]

are you using maven?

[tall ridge]

but I think if you make the list static it would fix everything

[proud basin]

who taught you?

[tall ridge]

That doesn't really help solve his issue tho

[proud basin]

Oh I know

im just curious

What was his issue?

[tall ridge]

Any random old information

it's in the chat

[wild inlet]

Yes

[pseudo raptor]

taking advantage of the moment, if I want to "call" an arraylist in a class from another package... how would I do that?

[proud basin]

Is it static or not?

[tall ridge]

I already told him to make it static

[pseudo raptor]

now I put it as static, but before it was just public

[tall ridge]

so does it work?

[pseudo raptor]

I will test now

[tall ridge]

and yes to your calling of methods from other classes and packages

[pseudo raptor]

`` @EventHandler
public void onQuit(PlayerQuitEvent e) {
Player p = e.getPlayer();
String nick = p.getName();

    if(PNaArena.contains(nick)) {
        p.getInventory().clear();
    }
}``

its correct?

[tall ridge]

It looked fine to me

[proud basin]

uh no

[pseudo raptor]

shouldn't I use OffinePlayers or something?

[tall ridge]

that exists

[proud basin]

wait... Is your list in a different class from the onQuit event?

[pseudo raptor]

no

[tall ridge]

#help-development message

that was my example

[proud basin]

So then why is he making it static?

[novel pendant]

Hey, does anyone know how I can fix this issue? Basically what happening is when I load the server, it's supposed to start the plugin when launching the server, but for whatever reason, the only way to get it working is to do the reload command. Im aware that its a problematic command, but the plugin doesnt work at all otherwise. Here's my on Enable

@Override
    public void onEnable() {
        instance = this;
        // THIS MUST BE FIRST ^

        this.getServer().getPluginManager().registerEvents(this, this);

        CTeam redTeam = TeamManager.getInstance().registerNewTeam("redTeam", "[RED] ", ChatColor.RED);
        CTeam blueTeam = TeamManager.getInstance().registerNewTeam("blueTeam", "[BLUE] ", ChatColor.BLUE);

        redTeam.getBukkitTeam().setAllowFriendlyFire(false);
        blueTeam.getBukkitTeam().setAllowFriendlyFire(false);

    }

I don't see anything wrong but maybe I'm missing something

[proud basin]

if it's in the same class

[pseudo raptor]

oh, so, I removed the static and left it so public

I'm trying to literally do everything I've learned in this short time

[proud basin]

Show me your entire class

[pseudo raptor]

Some strings are in Portuguese-br, is there a problem for you?

[tall ridge]

not for me...

[proud basin]

nope

[sharp bough]

why is private KitManager kits; null if i do it like this
but private final KitManager kits = new KitManager(); works just fine? im trying to call a class without creating a new instance of it

class: https://paste.md-5.net/ijerurofil.java

[quiet ice]

private KitManager kits; = private KitManager kits = null;

[tall ridge]

unlesss... kits = new KitManager();

[quiet ice]

no

[sharp bough]

that makes sense..

[quiet ice]

this applies to every Object, primitives are an exception here

[sharp bough]

i now see it haha

[quiet ice]

this is also why you cannot do private final KitManager kits; without assigning it (the kits variable) at the constructor

[tall ridge]

kits = new KitManager();```
is no? geol?

[sharp bough]

so should i make it static?

[sharp bough]

but thats creating a new instance of the class

[quiet ice]

it's still the same to
private KitManager kits = null;
kits = new KitManager();
just not explicit

[quiet ice]

why static?

[sharp bough]

to acces the data without creating a new instance

right?

[tall ridge]

yes I know it's null first

[proud basin]

Did you get it to work?

[quiet ice]

if you do not need an instance then make your constructor private, the class (KitManager) final and make the constructor throw the UnsupportedOperationException

This should prevent you from doing anything wrong

[tardy delta]

if a player is flying and i use player.setAllowFlight(false); does he falls out of the air?

[sharp bough]

yes

[tardy delta]

ah sadly yes

[urban lava]

wher is a good tutorial on how to establish commands and stuff

[dusk flicker]

?wiki

[undone axle]

https://www.spigotmc.org/wiki/

[sharp bough]

TheSourceCode has really good tutorials

[urban lava]

thanks to both of you guys

feel free to ping me btw

thats how i know to check

[dusk flicker]

It woulden't be a player, itd be an OfflinePlayer, and then you can use .getUUID or a similar method

[wild inlet]

Is there any way I can adapt the specialsource remapping to also install the mojang mapped version to my m2 for use as a dependency?

[dusk flicker]

also, if its a player name remove the UUID.fromString

Just caught that now

[wild inlet]

https://hastebin.com/gupuxefica.xml

[dusk flicker]

I know

there isnt a great way to do it

yes

Just it's not recommended as names arent unique

https://cdn.rackdevelopment.tech/img/HZekXktMhI.png

[wild inlet]

@ivory sleet Know anything about this specialsource stuff?

[dusk flicker]

https://cdn.rackdevelopment.tech/img/56Nv0NVjJT.png

hmm

I suck at math so maybe someone else can help lol, but if you convert that it seems right to me

[tired dagger]

Am I designing this Config properly? I feel like I am doing it wrong because other classes can create an instance of the Config class so I feel like that will lead to future issues.

[upper mica]

Hello, is there a way to increase how many slime blocks can piston push?

[dusk flicker]

looks fine for me, not sure why you needed a class for a config but it works I guess

[tired dagger]

I didn't wanna clutter the main class

[sturdy patrol]

I don't see an easy way. I've not looked into it, but maybe, maybe creating a custom server jar patch?

I don't think my proposition is a good idea though ^^'

[ivory sleet]

?

The Server#getOfflinePlayer(name) one?

[vale cradle]

What would be the better way to listen when a class gets loaded?

I'd like to inject code in them ;p

[eternal oxide]

He's talking about the code written by md-5 that is used in buildtools which is all rights reserved.

[ivory sleet]

😌

[onyx shale]

id like to also inject somt..

nvm

[tired dagger]

Rack, you think I should put the Config in the main class anyway. Does putting it in a separate class seem redundant/more complicated?

[vale cradle]

I was thinking to override the classloader with my own implementation and the previous classloader as parent but I'm not totally sure how spigot and the other plugins will take that since they use a classloader for each

[tired dagger]

Why don't you just use the class constructor? Or do you mean in a case where it is reloaded?

[vale cradle]

I'd like to cover EVERY class available

From NMS-like classes to plugin library ones

[sharp bough]

why isint kitsInv the same as event.getInventory if i create both inventories using the same method

[earnest sonnet]

don't do that 🤦‍♂️

[sharp bough]

do what

[tired dagger]

Pretty sure because they're separate instances

[sharp bough]

wdym

[tired dagger]

Your private final Inventory kitsInv = new InventoryGuiManager().buildKitsInv(); is a different instance than event.getInventory()

the event.getInventory() is fired when the event occurs whereas the kitsInv = new InventoryGuiManager().buildKitsInv(); is just creating a new instance

You'd need to grab the event.getInventory() instance, not create a new one

[sharp bough]

what

i always do it like this

[mystic tundra]

What are some features of NMS? I know you can modify a player’s gameprofile and make custom entities, but is there anything more?

[sharp bough]

i dont get why its not working now

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

this for example

i made it a while ago

and works just fine

[whole stag]

To sum it up the features are "don't"
