wut

[broken elbow]

the problem is that paper users are not dumb. we need the spigot users because they're the dumb people that pay for our trash plugins /s

[lyric gyro]

feather uses server internals from Spigot, can you send your build.gradle?

[worn jasper]

understandable, I shall switch to spigot.

uh to start with, this is not gonna work

sourceCompatibility = '1.17'
targetCompatibility = '1.17'

thanks discord

[dense drift]

yes, use 1.19 wtf

[icy shadow]

rofl

[dense drift]

waiting for em to send the actual answer xD

[lyric gyro]

try changing this

compileOnly 'ca.tweetzy:feather:3.1.0'

to

compileOnly('ca.tweetzy:feather:3.1.0') {
  exclude('org.spigotmc')
}

[worn jasper]

why so

oh wait yes

don't

Versions after 9 dont have a dot, is just 10, 11, etc.

[sterile hinge]

just use https://docs.gradle.org/current/userguide/toolchains.html instead

[twilit delta]

What event is called when Water and Lava come together to make obsidian/cobblestone?
1.8.9

[odd prawn]

It's not an event I think, you could check it with a blockupdate probally

[proud pebble]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/event/block/BlockFromToEvent.html

its in the docs for 1.8.8 so id assume its there

[twilit delta]

Does that work on 1.8.8? I heard that the BlockFormEvent is broken on 1.8.8

[proud pebble]

¯_(ツ)_/¯

i dont develope for 1.8.8 so no idea

[twilit delta]

🤔

BlockFromToEvent has 1 extensions, 1 implementations, 1 all implementations, 7 methods, and  3 fields.

Description:

Represents events with a source block and a destination block, currently only applies to liquid (lava and water) and teleporting dragon eggs.

If a Block From To event is cancelled, the block will not move (the liquid will not flow).

Making a plugin with kotlin and using kotlin reflect for something. The correct versions of kotlin and kotlin reflect are given in the libraries section of plugin.yml. Getting this error when my plugin tries to use kotlin reflect

[orchid wyvern]

The server logs show the correct version of kotlin and kotlin-reflect are being downloaded by spigot

libraries:
  - org.jetbrains.kotlin:kotlin-stdlib-jdk8:${kotlin_version}
  - org.jetbrains.kotlin:kotlin-reflect:${kotlin_version}```

[dense drift]

Why do you use jdk8 with jdk16 or whatever

[orchid wyvern]

No other kotlin stdlib afaik

I haven't checked in a while, maybe I'm wrong

I think also using kotlin-stdlib might be okay, but I don't think that is the issue here

[sterile hinge]

are you additionally shading something?

[orchid wyvern]

I didn't think you need to if you used the libraries attribute in the plugin.yml

[merry knoll]

shading is a bit safer, libraries feature is a bit iffy still afaik

[orchid wyvern]

Yeah, I just never liked shading kotlin because it makes the JARs huge even for small plugins

I guess if that's the only option then that's what I'll have to go with

This approach has worked in the past with kotlin-reflect though, so not sure what's changed

Oh wow, restarting the server and it seems to work fine

That's odd?

That probably should have been one of the first things I tried. I don't like that fact that I know it's a possibility though

[wet dragon]

yo anyone devs looking to make a server to co own i have a few custom gamemode ideas and wanna make a server but i need a dev to make it

[proud pebble]

#992627658229809162 or #992627660146626601

[wet dragon]

im service muted for sum resone

[proud pebble]

tho developing for a server usually includes getting paid real money, co owning a server isnt really payment or really that valuable

[wet dragon]

whats like a normal rate for a dev to get paid is it like hourly or by the project

[proud pebble]

depends on the dev, most do it by the project afaik, so like per plugin.

[wet dragon]

gotcha

[merry knoll]

game modes etc will usually cost 100+ $ usually

[proud pebble]

tho ive never done that so im not entirely sure.

[merry knoll]

medium size stuff is around 50 - 100 range

[wet dragon]

alright thank you

[wet dragon]

what about like a server setup with the main core being custom

[merry knoll]

i personally would not take a request like that

[wet dragon]

how come?

[merry knoll]

you need to provide exactly what you want

otherwise it drags on

[wet dragon]

oh no i mean like

say i want a prision server

i wanna buy a server setup from them

[merry knoll]

all custom coded plugins?

[wet dragon]

but the plugins custom most of them like the prision core

most not all

[merry knoll]

around 1k probably

prison has a lot of stuff in it that needs to be done

but if you are fine with using external stuff when available

cost should drop a lot

[wet dragon]

alright cause u usally want a fewq custom fetures

[merry knoll]

if i were you, i would set up the server as much as you can

then buy the features one by one

rather than pay someone to do all

[wet dragon]

hmm

[merry knoll]

like, if you need a mining plugin

just buy that specifically

[wet dragon]

smarth alright

do u know what jailbreakmc is

[merry knoll]

not really, is a spin off of prison servers?

[wet dragon]

yea but its not like op prision

its like

[merry knoll]

its preferable for developers as well usually

[wet dragon]

more simple

[merry knoll]

since its quite common to get the "hey can you add this too" as a major feature

[wet dragon]

do you know anythin g abt dev

[merry knoll]

about developing?

yes

[wet dragon]

yea

ok i have a qustion

is it possible to do a plugin for prision where its like ur own cell like an island for skyblock but its a prision sell and u can upgrade the size and stuff and all the blocks will change

for like an upgrade

[merry knoll]

yeah quite possible

[broken elbow]

it definitely is possible

[wet dragon]

hmm alright

thank you

one more qustion

[merry knoll]

if you want it properly done with instancing though, you would need an experienced dev

[wet dragon]

alright

[merry knoll]

otherwise player count scaling is a gonna be an issue over 100+ people

[broken elbow]

if done very badly it might take less than 100 players :)))

[wet dragon]

do you think a good game mode would be kinda like prision but the mines are like a sand and insted of a pick axe its a shovel that you upgrade

[merry knoll]

anything can be a game mode

but you need to think about it way more than just

"yeah you just want a cell with sand in it"

[wet dragon]

oh no i have

thats just a small explination

[merry knoll]

its basically skyblock

with that

[wet dragon]

where is the best place to find devs

like good ones

[merry knoll]

here is okay

ask for their portfolio

[wet dragon]

ok what do i look for

[merry knoll]

#992627658229809162 #992627660146626601

big projects

skyblock etc type plugins

[wet dragon]

what about like a free lancer?

[merry knoll]

i would go with someone familiar with mc landscape personally

[wet dragon]

hmmm alright

thank you

[dusky harness]

Fiverr 💀

[wet dragon]

ewww

i dont like fiverr

[merry knoll]

post a request here and get quotas from developers

[wet dragon]

its too easy to get scammed

[orchid wyvern]

definitely a lot easier to get scammed over discord than fiverr so be careful

[wet dragon]

wow really

[broken elbow]

that's why you usually want to ask for portofolio and maybe even look them up and see maybe reviews, or posts about them

[merry knoll]

this

[wet dragon]

ohh good ida

wow yall are alot of help

[merry knoll]

and do a percentage up front

and total once its finished

and they show it working

[wet dragon]

how should i pay them like half first then half after?

or all after the work is done

[merry knoll]

depends on size of project usually

i always take some upfront personally

[wet dragon]

what abt like a 100$- 200$ game mode

[merry knoll]

unless its a small one

[broken elbow]

you can decide with them this, but you don't want to give full pay at the start, and NEVER use F&F (family and friends) payment methods. Even if other methods take a cut, at least you have a way to get your money back if they scam you

[wet dragon]

ohh

alright\

[merry knoll]

yes, business payment is king

[wet dragon]

should i alway use paypal

[broken elbow]

not necesarely

I personaly use Stripe

[merry knoll]

doesnt matter much as long as payment method is credible

just dont use crypto

[broken elbow]

[wet dragon]

why not crypto

[broken elbow]

bcz you can't get it back

[merry knoll]

no way to charge back

[broken elbow]

when its gone, its gone forever

[merry knoll]

or do anything

[wet dragon]

ohhh

gotcha

[merry knoll]

also make sure to discuss source code etc

as in if you will receive full source code once done and if the plugin is exclusive to you

[wet dragon]

oh yea shouldthey give me the sorcecode too?

[merry knoll]

yes normally

but i have seen people get scammed with that in the past

where their plugin gets released to public after

or gets sold to others

[orchid wyvern]

coming back to this, what's the process usually? Haven't had the chance of working on large gamemodes that have needed it. How much actually has to be done by a developer these days, I imagine theres tools that just monitor resources and scale automatically? I know about kubernetes and docker but don't really know how they play in

[wet dragon]

so just go to a very trusted dev

[merry knoll]

kubernetes is okay, but you kinda want a custom solution usually honestly

a basic script can do wonders

[wet dragon]

have yall heard condor services?

[merry knoll]

no idea honestly

[wet dragon]

they do free lancing to make servers

they have worked with servers like vipermc

[merry knoll]

big service groups are hit and miss

some are great some are just meh at best

worst case you get scammed

[wet dragon]

yea

[merry knoll]

i think for you, i would go with a singular dev and maybe someone to configure your stuff

[wintry grove]

if you are willing to go that way I would recommend senior studios

[merry knoll]

then you can comission the same dev again in the future as well

[wintry grove]

havent commissioned them yet but from what I have seen they are good

[wet dragon]

im in there discord yea

[wintry grove]

but also yeah

If you want to make a small server or so a single dev should be enough

just make sure its one you can trust

[wet dragon]

not like a dev team one person can do it prolly?

[merry knoll]

our network got burned plenty in the past from service groups, i am semi biased against them i feel like

the advantage is usually

is that if you commission the same guy

[wintry grove]

if it is small

[wet dragon]

so i should hire someone to dev and to config u say?

[merry knoll]

you can probably hire them in the future

if your server grows

[wet dragon]

i mean like hire them for the project

[wintry grove]

the problem is that you have to manage them and make sure they do the work

you can also hire a team of devs

[merry knoll]

yes ^

[wintry grove]

one by one

[wet dragon]

ok

[wintry grove]

but again the same problem

but bigger

[merry knoll]

what we do currently is to hire people per mode

and they maintain the gamemode as needed

add features / bugfixes etc

but for your case where you want to make a prison server of sorts

a dev and one guy to configure the rest

is enough i feel like

if you can configure plugins yourself

even better

[wet dragon]

i config all my servers but im too lacy and out of ideas

tbh

[wintry grove]

I'd rather spend the time configuring it myself

[wet dragon]

ok

ill do that

[wintry grove]

so that you can know how does it work

[wet dragon]

one thin g that annoys me is crates

[merry knoll]

if you want a honest opinion

[wintry grove]

and how it is configured

[wet dragon]

i never know what to put in crates

[merry knoll]

i would make the server to the best of my ability

then hire a dev to fill the gaps as you need it

[wintry grove]

why even do crates

[merry knoll]

crates are great for income

[wet dragon]

well im working on a skyblock server rn

[merry knoll]

gotta get the gambling addiction going

[wet dragon]

^^^^^

what are sum fetures yall would like to see in a prision server or skyblock that isnt already a thing or else something changed

[merry knoll]

feel like #minecraft is probably better

[wet dragon]

alright

[merry knoll]

this channel usually has programming questions

[wet dragon]

alright thanks everyone

[bitter basin]

whats the best way to take a player number input, sign or chat

[lyric gyro]

Get them to build a 7-segment display with redstone lamps and light up the number

Conversation API exists too

It's conversation between plugin and player.... I don't know why it's named "conversation" lol

[icy shadow]

to this day ive never actually seen anything use the conversation api

[lyric gyro]

Me neither

It's like java.util.Scanner, never seen anyone actually use it, but it's full of neat methods

Any help as to this weird issue im getting?

I give a player full colored leather armor and its fine
they die and then I set it again to that color, its fine for 0.1 seconds but then it changes to red/dark blue for some reason

i tried clearing their armor as well and then setting it but it doesnt fix it

    public void setArmor(Player p) {
        p.getInventory().setHelmet(dyeArmor(new ItemStack(Material.LEATHER_HELMET), playerTeam.get(p.getUniqueId()).getColor()));
        p.getInventory().setChestplate(dyeArmor(new ItemStack(Material.LEATHER_CHESTPLATE), playerTeam.get(p.getUniqueId()).getColor()));
        p.getInventory().setLeggings(dyeArmor(new ItemStack(Material.LEATHER_LEGGINGS), playerTeam.get(p.getUniqueId()).getColor()));
        p.getInventory().setBoots(dyeArmor(new ItemStack(Material.LEATHER_BOOTS), playerTeam.get(p.getUniqueId()).getColor()));
    }

    public void clearArmor(Player p) {
        p.getInventory().setHelmet(new ItemStack(Material.AIR));
        p.getInventory().setChestplate(new ItemStack(Material.AIR));
        p.getInventory().setLeggings(new ItemStack(Material.AIR));
        p.getInventory().setBoots(new ItemStack(Material.AIR));
    }```

the methods im using

i also tried clearing the armor and then running a delayed task to set the new armor

still doesnt work

I printed out the getColor and its correct every time btw

[stuck hearth]

Is PAPI on the server?

[urban temple]

yea

/plugins output:
Plugins (4): DrainStealCore, CraftserveAgent, PlugmanX (Plugman), PlaceholderAPI

[broken elbow]

try restarting the server instead of reloading or using plugman if you haven't already.

[urban temple]

alright wait

[urban temple]

so uhh still nothing though no exception

it doesnt return the msg i wanted

[broken elbow]

try sending the message to console, see if its being sent there at least

[urban temple]

i should use getLogger to send it to console?

[broken elbow]

sure

[urban temple]

aight wait

it says this

[broken elbow]

when are you sending this? after parsing the placeholders or after?

[urban temple]

after

after or after makes sense

oops im late

help please

[hoary scarab]

You imported from geyser not spigot.

[lyric gyro]

I wrote a method for it a while ago in one of my plugins, hold on

    private void hideBossBarAfter(BossBar bossBar, int timeInSecs) {
        if (timeInSecs == 0) {
            player.hideBossBar(bossBar);
            return;
        }
        double timeDecrease =  (double) 1 / timeInSecs;
        plugin.getServer().getScheduler().runTaskTimer(plugin, task -> {
            if (bossBar.progress() <= 0.0) {
                task.cancel();
                player.hideBossBar(bossBar);
                return;
            }
            bossBar.progress((float) Math.max(0.0, bossBar.progress() - timeDecrease));
        }, 0, 20L);
    }

Then you'd just make your bossbar with the adventure API, and pass it to the method

I am gonna try it later, ty

[errant kraken]

How can I eval a String? I tried using the JavaScript and Nashorn engines, but they were removed since Java 15

[sterile hinge]

eval a string representing what?

[errant kraken]

a condition

like a comparison

[sterile hinge]

I mean there is no universal way to evaluate every expression, as that fully depends on the format of the expression

[errant kraken]

I don't need an "universal way", I just need something that can eval this %krownedlevels_level% >= 20

[sterile hinge]

string.split(">="), trim, parse both integers, do a >= b

[errant kraken]

so basically there's no engine that can do that?

[sterile hinge]

as I said, there is no universal way to evaluate expressions

[dense drift]

If you have basic conditions like that one, is easy to make your own system

[errant kraken]

I tried using the graal.js engine, but it bloats my jar and makes it MBs bigger

[sterile hinge]

graaljs can only evaluate js

[errant kraken]

that's good enough, idk why you're under the impression I need to be able to eval all languages known to man

[broken elbow]

well, you didn't specify that you need a javascript evaluator

[errant kraken]

I said I tried JavaScript and Nashorn which both eval JS, so I thought you got it

[sterile hinge]

conditional expressions can look different than js, so god knows what you really want

[errant kraken]

omg

[broken elbow]

what I got from that, is that you tried javascript engines and you didn't like them so you were looking for different types of evaluators. Anyways, there's plenty of javascript engines out there like: Nashorn, Rihno, QuickJS, etc

pretty sure there's a wiki page with a long list of them

there we go https://en.wikipedia.org/wiki/List_of_ECMAScript_engines

[errant kraken]

My issue is that JavaScript and Nashorn don't work, their script engine objects return null, so i looked the issue up and apparently they removed them in Java 15

[broken elbow]

yeah. you'll have to shade one

if you want to use it

[dense drift]

If your plugin is for 1.17+ you can use the library thing to download them at runtime

But again, for some simple conditions, is just easier to make your own system imo

[errant kraken]

it's configurable tho, who knows what conditions the admins will want to use

[dense drift]

They will use what conditions you allow them to, wdym

[sterile hinge]

that's why you need to know what you want

[dense drift]

By simple I mean != == > >= < =<

[lyric gyro]

I'll negate you

[dense drift]

No Emily..

Whats the use case for this? @errant kraken

[errant kraken]

I am making a portal that will only teleport those who meet 2 conditions: a JS condition and an item condition

[karmic arch]

Gday Lads!
I recently faced some big issues with my Plugin Code, and i hope that anyone here can help me.
The Idea is, that if a Player Clicks a Specific Item in the Inventory (Command Block in this Case), the current inv disappears and a the new one opens up.
Any Help?
Here's the Code:
https://srcb.in/KRh35LwcpH

[hard wigeon]

How does one check if a hit is a critical hit, or a normal one with spigot?

[leaden sinew]

Probably check their downward velocity

[lyric gyro]

I've been spending a lot of the day trying to reverse engineer EssentialsX's build project setup. Yes, I've failed to try and build it from scratch several times. I basically want the same setup they've got for their projects, the code-style checks, junit and the multi-project building and compiling with a runServer.

Is there any helpful guides or simpler (than Essentials) code to look at to help build a system like theirs?

[lyric gyro]

in your damage event just check player#isOnGround() tbh

[tight junco]

i don't believe it has to be jumping to be critical

[lyric gyro]

Was that recently changed?

I know in 1.12, the player must be like falling/not on ground, cant be on like a ladder or in water and cant be sprinting/on a mount

[tight junco]

i might be delusional

[lyric gyro]

unless it was changed since 1.12, which easily could have happened in which case im just dumb, I'm going to go with delusional xD

[tight junco]

[hard wigeon]

What about attack cooldowns and stuff

[lyric gyro]

Yeah I think it's if your damage is below like 80% or smth

I'm pretty sure you can look at the logic in Spigot and just copy it

[hard wigeon]

It should totally be exposed

[lyric gyro]

I'm looking at a thread from a few years ago

let me see if I can dive into the source to make sure its still accurate

[lyric gyro]

    @SuppressWarnings("deprecation")
    public boolean isCritical(Player player) {
        return player.getAttackCooldown() > 0.9F && player.getFallDistance() > 0.0F
            && !player.isOnGround() && !player.isInWater() && player.getActivePotionEffects().stream()
            .noneMatch(p -> p.getType().equals(PotionEffectType.BLINDNESS))
            && player.getVehicle() == null && !player.isSprinting();
    }

that should do you just fine.

[hard wigeon]

Is that 1.19 decompiled?

If so, thanks

[lyric gyro]

No, it's a custom method I built off of the requirements

[hard wigeon]

Ah

Well ty

[lyric gyro]

np

[slim estuary]

Does anyone know the 1.19 NMS name for noclip? I know it’s just .noclip for 1.16 but things have changed

[worn jasper]

Uhm, so rn, I was going to check for every single thing I get from the config and report and error in case it doesn't find it, the thing is, is there no other way of doing this? Seems like DRY to be doing this like 15 different times...

[pulsar ferry]

Sir you can use code blocks

[dusky harness]

🥲

[ornate salmon]

Hello, in Bungeecord API, does PreLoginEvent.getConnection().getUniqueId() returns the player's UUID? Is it the same as PostLoginEvent.getPlayer().getUniqueId()?

[lyric gyro]

Examples of attributes which are not available include their UUID.
you sure that works?

[worn jasper]

fair enough

Either way I just assume config verification are a bunch of checks and there is nothing we can do

[ornate salmon]

Ok, can I obtain their UUID from LoginEvent or PostLoginEvent?

I want to perform database action based on the player UUID

[lyric gyro]

hm I believe LoginEvent is fine

90% sure

[ornate salmon]

But it's still LoginEvent.getConnection() not getPlayer()

[lyric gyro]

yes but the uuid should be populated by then

[ornate salmon]

Ok let me have a try

Also

I should perform the database action asynchronously from the async LoginEvent right?

Should I start a new asynchronous task per LoginEvent or have a single thread for all LoginEvents

[lyric gyro]

yeah, you should, and you should use the scheduler; on the event itself you "register an intent"
(https://javadoc.io/static/net.md-5/bungeecord-api/1.16-R0.4/net/md_5/bungee/api/event/AsyncEvent.html#registerIntent-net.md_5.bungee.api.plugin.Plugin-)
and "complete it" when your async action is done
https://javadoc.io/static/net.md-5/bungeecord-api/1.16-R0.4/net/md_5/bungee/api/event/AsyncEvent.html#completeIntent-net.md_5.bungee.api.plugin.Plugin-

See how LuckPerms does it (it also loads stuff from a database), it registers an intent before firing its async task and completes it when it's done doing it
https://github.com/LuckPerms/LuckPerms/blob/ad08b158f7d0d6a19c5da6b10f43d1765aec652f/bungee/src/main/java/me/lucko/luckperms/bungee/listeners/BungeeConnectionListener.java#L77-L110

the idea behind the intent stuff is "oh i'll be doing some work async, let the event continue to other listeners but don't continue the login process until i'm done"

[ornate salmon]

Cool let me see

[ornate salmon]

Looks like LuckPerms uses JDBC instead of JPA

[lyric gyro]

yeah I mean how it does the query specifically isn't exactly relevant

What I was trying to point out was more of the usage of the intent

[granite mountain]

any api for custom entities not using nms for 1.19?

coz i hate nms

[ornate salmon]

Is it possible for two players to login simultaneously, and should I access the database for the two players in the same JDBC Connection (assuming no connection pool), or separate?

Is creating a Connection expensive such that I should perform database action for multiple players in the same Connection?

[lyric gyro]

eeh you should definitely use a connection pool library, it'll take care of all the nasty lifecycling, hikaricp is the go-to solution for jdbc, you can configure stuff like max pool size, max lifetime and whatevs, manually trying to take care of this stuff is hell
I am not familiar with jpa's ecosystem but surely there has got to be solutions as well 😅

Is it possible for two players to login simultaneously
possible? yeah, how likely that is depends on the size of the network

[ornate salmon]

Ok thanks!

[fiery roost]

if i add this

    String parsedColors = ChatColor.translateAlternateColorCodes('&', parsedPlaceholders);```
the plugin wont enable for some reason if i remove it itll enable why?

[sterile hinge]

look at your logs

[merry plover]

If you need it, then buy it, noone is gonna give it to you, also you would only end up with malware that way

[tropic socket]

well, thanks

[sterile hinge]

Or use a free alternative

[high edge]

Can we get a yeet?

[robust crow]

Don't ask for plugin leaks, purchase the plugin or use an alternative.

[granite mountain]

anyone got a api for making custom enites i hate nms, for 1.19 btw

[lyric gyro]

[broken elbow]

I'd personally recommend you use the base64 serializer instead. It lets you serialize an entire inventory to a base64 string and then it also gives you a method to deserialize. Its much more compact and nicer. https://gist.github.com/graywolf336/8153678 but anyways if you want to continue with the YamlSerializer, you just get the item list, get the player's inventory using Player#getInventory, and then and then use a simple for loop that goes from 0 until list size, and use the PlayerInventory#setItem method to add set the item

d;spigot PlayerInventory#setItem

[uneven lantern]

org.bukkit.inventory.Inventory#setItem

void setItem(int index, @Nullable ItemStack item)```

Description:

Stores the ItemStack at the given index of the inventory.

Parameters:

index - The index where to put the ItemStack
item - The ItemStack to set

if you can do it better then please share. ok. thank you. and bye nerd

[sharp hemlock]

just a simple regex question, but based in java. how would i make it so you it doesnt match the ending : next to the }

[lyric gyro]

d;paper ItemStack#serializeAsBytes

[uneven lantern]

org.bukkit.inventory.ItemStack#serializeAsBytes

@NotNull
public @org.jetbrains.annotations.NotNull byte[] serializeAsBytes()```

Description:

Serializes this itemstack to raw bytes in NBT. NBT is safer for data migrations as it will use the built in data converter instead of bukkits dangerous serialization system.

Returns:

bytes representing this item in NBT.

How do i make so when players leave the server their inventory gets cleared

package knockbackffa.knockbackffa;

import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerQuitEvent;

public class LeaveEvent implements Listener {
    public void onPlayerQuit(PlayerQuitEvent e) {
    Player player = e.getPlayer();



    }
}```

[inner jolt]

player.getInventory().clear();

Should work

[torpid raft]

no

[crude charm]

Did not work.

[crude charm]

I also registerd.

[inner jolt]

What about clearing their inventory when they join instead?

[crude charm]

But they also get stuff when they join

wiat

i can clear it

and then give them stuff

im dumb

thanks

lemme try thaty

[inner jolt]

👍

[crude charm]

Does not work

hm

@inner jolt

help me

[inner jolt]

You might have to update the inventory afterwards?

[crude charm]

Wdym

[inner jolt]

player.updateInventory(); to force update the inventory after changing it

[crude charm]

Should it update before

or after

they join

Like

Should it update before the player.getinventor

or after?

@inner jolt

[inner jolt]

after

[crude charm]

Lemme try

Did not work

nvm

it did work

Thanks @inner jolt

[inner jolt]

No problem 👍

[wintry grove]

how can I make a regex to only match the first colon in a string

[wintry grove]

or I want to make a regex for separating this string:
" (Rank) StarL0stGaming: Hello"

the rank would be a string

the name another

and the message another

how would I do so?

[dusty frost]

string.split(" ");

Or you could match each part depending on like if there are always parentheses around the rank and a colon + space before the message

[somber light]

hello, let's say that I can't use Thread.currentThread().getContextClassLoader().getResource(".."); and as a parameter I get the main class of a plugin
since the plugin is supposed to work on spigot and bungeecord I decided to have the following structure:

 me/oreoezi/plugin:
   - spigot
   - bungeecord
   - universal

Therefore my main class is in me/oreoezi/plugin/spigot, which makes it impossible for me to just list the files of the directory using

URL url = main.getResource("resources/" + path);
File dir = new File(url.toURI());
dir.list();

main is a Class<?> and path is a string, this code would work if main was part of me/oreoezi/plugin but wouldn't work if the main class is in a subpackage
this is the structure of my code https://media.discordapp.net/attachments/898308178058559550/1003616988121276426/Screenshot_at_2022-08-01_13-48-50.png
so now the question remains; how would I write a function that when given the main class and "folder/" as a parameter it will return a string array with the names of all the files inside of that folder in the resources directory

[sterile hinge]

I don't see how this is related to the package of the class at all

[somber light]

that's what I thought too

but for some reason it makes all the difference in the world

[sterile hinge]

I doubt that

[somber light]

private String[] listResourceDirectory(String path) {
        URL url = main.getResource("resources/" + path);
        if (url == null)
            return new String[0];
        try {
            File dir = new File(url.toURI());
            return dir.list();
        } catch (URISyntaxException e) {
            e.printStackTrace();
            return null;
        }
    }

I tested this and it worked on my other plugin, the only difference in setup is the package structure
another thing worth mentioning is the function for copying a file from my resource directory still works despite listing the directory doesn't

private boolean writeFile(String path, String local_path) throws IOException {
        Path dest = Paths.get(folder + path);
        if (new File(folder + path).exists()) return false;
        Files.copy(main.getClassLoader().getResourceAsStream(local_path), dest, StandardCopyOption.REPLACE_EXISTING);
        return true;
    }

[sterile hinge]

1. don't mix the old file api with the new file api everywhere
2. the package structure has no effect on functionality unless you found a bug
3. you can't represent an entry in your jar file using Fileafaik

[somber light]

You actually can do the third

It is worth mentioning that if i did the same thing but used the class loader to get the resource i would get an url to it but it would give me an error saying URI is not hierarchical

When loading the file

I also tried "../resources/" + path and "/../resources/" + path but to no avail

[sterile hinge]

not sure where that "resources" is even coming from

[somber light]

that is the folder in which i store the files

[sterile hinge]

yes, this is point 3

[sterile hinge]

in the jar file?

[somber light]

correct

[sterile hinge]

well as I said, you can't create a File object from that URL, so you can't list the dir content

[somber light]

I again state that I could just fine on my other plugin

[sterile hinge]

well if you know the solution, just do the same again

[somber light]

I don't

my only assumption was that it was due to the package

but,as you stated earlier, it wouldn't make much sense

without using files, how can I get the names of the files inside that folder

[sterile hinge]

the content of a jar file aren't Files, you'll need to use something to open the jar file and go traverse its entries

[somber light]

is there not another way, I am just interested in knowing the names of those files

not reading them

[somber light]

as the writeFile method can already copy them outside of the jar

[sterile hinge]

because it works on an InputStream, which means it reads the files

[somber light]

correct

[sterile hinge]

but if the resource is in a jar file, that means reading an entry from the jar file

[somber light]

those files are also inside of the jar

if I try to use getResourceAsStream on a folder and it returns an InputStream can I use that inputstream to get the items inside of that folder?

[sterile hinge]

I don't think so

[edgy lintel]

why is lambda function async lol

[sterile hinge]

?

[edgy lintel]

when trigger a lambda function from an inventory event, the bukkit api responds with the fact that i cant trigger closeinventory(lambda function) from async
or i assume inventories are handled in an async way or sth?

too lazy to decompile the source code

[sterile hinge]

show your code

SlimeWorldManager is a good option for arena regeneration in minigames right?
What about ores regeneration? I mean, if a minigame where players mine resources is made, how to randomize (efficiently) the ores when regenerating the arena too (with SlimeWorldManager). Would it be by using a specific material in the arena and then looping arena to replace that material with random ores or there is a better way?

[grand island]

Hello, is there a way i could listen to /papi reload and re-register expansions from my plugin?

[shell moon]

why would you do that

[broken elbow]

exactly what Alonso said. Why?

[grand island]

because expansion i register disappears after placeholder api reload

[shell moon]

what i thoo

[broken elbow]

that's because you're not overriding the persist method

[shell moon]

persist true

[broken elbow]

override it, and make it return true

[grand island]

oh

didn't know, thanx

[shell moon]

if someone know, ping me

[merry knoll]

it good

[shell moon]

[merry knoll]

you probably need to change the ores afterwards

[shell moon]

ik

question was whats the best way

[merry knoll]

all slime world manager does is to save and load from slime format

[shell moon]

ik

[broken elbow]

yeah. their question was, what's the best way to generate these ores after loading the world using SWM

[merry knoll]

ah? depends though no?

if block locations are known simple randomization is good enough

but if not you probably need to implement some procedural generation logic using noise

How can I play videos doesn't matter what file format on a 2d game based on Java Swing?

Maybe I could export the video as a list of images and a .wav file?

[somber light]

I fixed the issue in case anyone else has it, and I learned a bit along the way.

1. The package that your class is in does matter, if you want to use getClass().getResource("text.txt") and your class is in me.dev.plugin your text.txt file should be in resources/me/dev/plugin/
2. You can prevent that by using getClass().getClassLoader().getResource()
3. You cannot load directories as java.io.File inside a jar
4. Unlike directories outside of a jar, using getResourceAsStream in order to get an InputStream won't actually get you a directory listing, as expected

    private String[] listResourceDirectory(String path) throws URISyntaxException, IOException {
        URL url = getClass().getClassLoader().getResource(path);
        if (url == null)
            return new String[0];
        FileSystem fileSystem;
        fileSystem = FileSystems.newFileSystem(url.toURI(), Collections.emptyMap());
            Path resourcePath = fileSystem.getPath(path);
            List<String> resourcesNames = Files.walk(resourcePath, 1)
            .skip(1) //the dir itself?
            .map(p -> {
                String name = p.getFileName().toString();
                if (name.endsWith("/")) 
                    name = name.substring(0, name.length() - 1);
                    return name;
                })
            .sorted().collect(Collectors.toList());
            fileSystem.close();
        return resourcesNames.toArray(new String[resourcesNames.size()]);
    }```
This code is a modified version of https://stackoverflow.com/a/49570879 
This worked like a charm, although I'm gonna be honest, I don't know exactly what each line does, I might experiment with it if I have time.

[wintry grove]

sorry for late response, it was kinda late for me at that moment, but yeah I have tried string.split(""), but what I'm looking to do with the regex is that this same method returns the 3 string parts

I assume it is possible right?

I have used simply split(":") for splitting the rank and message

[dense drift]

\((?<rank>\w+)\) (?<name>[\w.]{3,16}): (?<message>.+) maybe something like this?
https://regex101.com/r/DIECJ6/2

[wintry grove]

let me try

cool it works

[dense drift]

the \d is not need btw

[wintry grove]

now the parentesis in the ranks is not actually in the chat message

I just used it for the explanation

the rank is a font character with an image

should I just change it with the character?

[dense drift]

good luck with that

because you most likely use unicoded symbols and I personally dont know how to make a regex accept that xD

[wintry grove]

pain

[dense drift]

though a split(" ", 3) would do the job

and then just remove the colon from [1]

[wintry grove]

doesnt it accept the unicodes tho?

I mean this should work

if I put the unicodes

or am I wrong

[dense drift]

idk how regex works with unicoded symbols

[dense drift]

try this

[wintry grove]

aight

used 2 instead of 3

it splits the rank

gonna try 3 now

[broken elbow]

well yes...

that is the max limit of splits

or whatever its called. so if you give it 2, it will split a maximum of once if it finds the char sequence you want to split at

so the resulting array will either have 1 or 2 elements

if its 3, it will split it a maximum of 3 times, so resulting array will have between 1 and 3 elements

[wintry grove]

ye

should probably use the second part

[dusty frost]

could also possibly look into using zero-width spaces if you're concerned about it, then you can set explicit break points wherever you want

[vital pecan]

constructor SimpleCommand in class com.plugin.simpleplugin.commands.SimpleCommand cannot be applied to given types;

i got this error

anyone know?

[wintry grove]

I did not understand a shit of what you said lol

I'm extremely new to regexes

it works now

tysm

shouldnt be a problem for now

[dusty frost]

so there's a character in unicode called a zero-width space

as the name implies, it has no width, therefore it is essentially not rendered

but it can be used to put breakpoints in where you want to split stuff, like in this case

you could put one after the rank and after the name if you ever swap away from using a colon

[shell moon]

someone?

[torpid raft]

is this actually something people do

on one hand it seems very easy and convenient

but it also sounds extremely hacky and like you'd get yelled at for even trying to add it

never touched build.gradle yet getting errors from it?

any help with this?

[dusky harness]

Don't use snapshot

Use releases

[tacit quail]

not sure what u mean by that

[dusky harness]

Use version 1.7.10

Oops I meant don't use beta

[tacit quail]

oh that makes more sense

[dusky harness]

Also kotlin and Java pluigins

Interesting

Using both langs? 👀

[tacit quail]

that was a mistake

i wanted to make it in kotlin but it wasnt converting

im gonna tryu it with maven

so far its working with maven

i just make a new project lol

[lyric gyro]

fairly certain the kt plugin adds the java plugin to the build environment

[dusky harness]

Oh

¯\_(ツ)_/¯

Makes sense

[tacit quail]

my pc is exploding from 1.19

wtf

[warm steppe]

Why is pdc not applying to my item? (1.17.1)

public static void setEnchant(ItemStack pickaxe, Enchant enchant, Integer value) {
    ItemMeta itemMeta = pickaxe.getItemMeta();
    itemMeta.getPersistentDataContainer().set(enchant.getNamespacedKey(), PersistentDataType.INTEGER, value);
    pickaxe.setItemMeta(itemMeta);
}

[icy shadow]

how do you know it's not applying

[stuck hearth]

Because

[warm steppe]

I print item enchant list in chat on my event

[lyric gyro]

can you show that

[broken elbow]

ugh. what is the PickaxeUtils.getEnchants method?

[lyric gyro]

that sure does look fine

[warm steppe]

public static Map<Enchant, Integer> getEnchants(PersistentDataContainer persistentDataContainer) {
    return new HashMap<>(){{
        put(Enchant.EFFICIENCY, persistentDataContainer.getOrDefault(Enchant.EFFICIENCY.getNamespacedKey(), PersistentDataType.INTEGER, 0));
        put(Enchant.FORTUNE, persistentDataContainer.getOrDefault(Enchant.FORTUNE.getNamespacedKey(), PersistentDataType.INTEGER, 0));
        put(Enchant.MULTI_MINE, persistentDataContainer.getOrDefault(Enchant.MULTI_MINE.getNamespacedKey(), PersistentDataType.INTEGER, 0));
    }};
}

[lyric gyro]

and how/where are you using setEnchant

[warm steppe]

in a command

public void enchant(Player sender, Enchant enchant, Integer value) {
    ItemStack pickaxe = sender.getInventory().getItemInMainHand();
    ItemMeta itemMeta = pickaxe.getItemMeta();
    
    PickaxeUtils.setEnchant(pickaxe, enchant, value);
    
    itemMeta.addItemFlags(ItemFlag.values());
    itemMeta.setLore(PickaxeUtils.getPickaxeLore(pickaxe));
    
    pickaxe.setItemMeta(itemMeta);
}

[lyric gyro]

you are overriding the meta after calling setEnchant

make it take an ItemMeta instead of an ItemStack

[warm steppe]

Thank you!

[nimble vale]

so PlayerDeathEvent is just for handling death event it has nothing to do with actually killing player

when i call the event i also need to kill player i guess

[merry knoll]

what, it fires when a player dies

so if you kill a player that event will also fire

[nimble vale]

what if i call that event in a plugin

Bukkit.getPluginManager().callEvent

with this

[merry knoll]

would fire the event without killing the player obviously

[nimble vale]

yeah

[merry knoll]

events are there to notify plugins not the other way around

[nimble vale]

and if i kill the player myself then again another event will be fired

[merry knoll]

ye it will fire two times

[nimble vale]

yeah then something wrong with my logic i guess thanks anyway

[merry knoll]

if you have other plugins, they could be cancelling the event as well (not sure if you can cancel death event) but maybe worth looking into

[nimble vale]

i just need to make a custom event or just create a method to use like events

idk if i need to create a event for this because i will be calling it from the same plugin

not gonna use for any other plugin

that event

[merry knoll]

i mean it depends, do you need to use it more than once?

if yes its probably an okay idea to use a listener pattern internally

if only once though, i personally would just use a function call and be done with it when your custom "event" fires

[nimble vale]

actually i just made a custom event which i think it's the best approach here

that didn't took a minute really

[dusty meteor]

can I install ecloud expansions using placeholderapi on my plugin, for exemple, can I install Player expansion using a method from my plugin

[merry knoll]

#placeholder-api probably a better place to ask

[dusty meteor]

ok thanks

[nimble vale]

i guess you can just run commands too

not the best but you have that

[dusty meteor]

exactly

[torn heart]

i'm using BoundingBox#raycast and it's detecting the player, which i don't want. any way to fix this?

[sterile hinge]

looks like custom logging?

[hoary scarab]

Thats just a debug when I run commands. Nothing to do with the command/plugin that I used.

[hoary scarab]

This is the client causing this right? Its not a bug but just looks bad. (When you have a long string)

[tacit quail]

I cant use .equals on getEnchtntmentLevel

am i misssing something

i can do it on .gettype()

[icy shadow]

it's an int so it doesnt have .equals

[tacit quail]

oh so what should i do instead for it?

[broken elbow]

usually, you can hover over it and it will tell you what's going on.

[icy shadow]

==

[broken elbow]

==

[tacit quail]

that really didsnt work

[icy shadow]

oh?

[tacit quail]

not a statement

[broken elbow]

no brackets

?

[icy shadow]

well you need to actually do something with the result

[broken elbow]

== 50

ohh

lmao. nvm yeah what bm said

[tacit quail]

its for an if statement though

[icy shadow]

so put it in the if

[broken elbow]

yeah. but you're closing the if statement.

with ;

[tacit quail]

omg

ur right

tysm

it worked

is there a more efficent way to write this?

[stuck hearth]

Store the inventory in a variable instead of calling it twice

[broken elbow]

d;spigot PlayerInventory#setItemInMainHand

[uneven lantern]

org.bukkit.inventory.PlayerInventory#setItemInMainHand

void setItemInMainHand(@Nullable ItemStack item)```

Description:

Sets the item the player is holding in their main hand.

Parameters:

item - The item to put into the player's hand

Requested by: BlitzOffline • spigot

[stuck hearth]

Or that

[tacit quail]

oh wow

[broken elbow]

set it to null

and it will remove it

[tacit quail]

ty very much

[broken elbow]

no problem

so, for FireworkEffectMeta, spigot's api mentions:

Represents a meta that can store a single FireworkEffect. An example includes Material.FIREWORK_STAR.
where do I Find a full list of this? Or is it just firework star and firework?

[dense drift]

just these two

Arrays.stream(Material.values()).filter(Material::isItem).map(ItemStack::new).filter(it -> it.getItemMeta() instanceof FireworkEffectMeta)

[broken elbow]

👍 don't need a list, was just curious. but thanks

[fiery pollen]

In the method World#createExplosion(), whats the biggest power you can pass in

or is there no max?

[fading stag]

Is there any doc about which mc version fits best with which java version? I can set sourceCompatibility
targetCompatibility from build.gradle.kts and IDK what should I set them to

[smoky hound]

did you figure this out? I've been having this issue with no stack trace on 1.19.1 and when I hover it just says java.lang.UnsupportedOperationException or whatever

[broken elbow]

well, I Know this:

• 1.18+ requires java 17+
• 1.17 requires java 16+

I also know spigot 1.8.8-1.12.2 only support java 8 I believe but paper 1.8.8-1.12.2 supports up to java 11 if I remember correctly. I Don't remember the rest

[fading stag]

I believe I need all versions (1.8-1.18) but thanks 😄

[lyric gyro]

always target the minimum you plan on supported

in your case, java 8 would be that

[fading stag]

I plan publishing multijar

[lyric gyro]

skull

good luck

[merry knoll]

java 8

[lyric gyro]

Hey ho

[torpid raft]

hey is for horses

[lyric gyro]

I want to make a Skyblock Plugin. What is the Smartest way to generate the World? using WorldEdit to load a Schmetica or can i Just Copy a World?

[lyric gyro]

that goes deep o.o

[torpid raft]

if it's skyblock just start with a void world and use either the worldedit api or just paste in the islands yourself (in code) as they are needed

[lyric gyro]

wym by paste the islands yourself

[torpid raft]

like instead of depending on worldedit place the blocks programmatically on your own

make your own worldedit to copy your island into each spot

[lyric gyro]

so hardcode block by block?

[torpid raft]

not necessarily hardcode

you can make a simplified island config and read from that

[lyric gyro]

can you load Schmeticas with my Plugin without depending on others

[torpid raft]

there might be a library out there for reading schematic files so that you dont need to depend on another plugin

but i've never looked into something like that so ymmv

[fading stag]

just tried 1.8 with java 17 and it worked is it normal?

[broken elbow]

you tried the server or have you tried compiling a plugin? because compiling a plugin shouldn't be a problem but according to reports I've seen in here before, the server jar doesn't work with anything but java 8. at least the spigot one

[fading stag]

Installed spigot 1.8 from get bukkit and opened it with java 17 temurin

[broken elbow]

interesting

guess I was lied to (never tested this myself)

[proud pebble]

btw dont use spigot, paper does have a 1.8.8 legacy build

[broken elbow]

yeah. but that wasn't their original question

[broken elbow]

this was

[proud pebble]

i was just adding something extra, didnt even see what they originally asked

when it comes to minecraft versions, its probably recommended to compile using a version of java that its minimum can me

so for 1.8,1.12,etc its java 8

1.16 is java 11, 1.17 is java 16 and 1.18 is java 17

[lyric gyro]

Sooo
In my Main I have an Array that contains commands. Now I want to check on Chat event if the /.... is in the Array. How do I do that

            if (event.getMessage().contains("/") && !Main.commands.contains(event.getMessage()))
            {
                event.setCancelled(true);
                event.getPlayer().sendMessage(PREFIX + "§cCommand not found.");
            }
``` why doesnt this work

[proud pebble]

cus a command is never sent through the chat event?

[lyric gyro]

BRUH

sorry

is there an event for commands

[proud pebble]

the event api isnt used for commands

[lyric gyro]

can I somehow prevent commands from being executed

via plugin

[proud pebble]

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

[broken elbow]

yes. there is an event fired when a command is executed

what lunaiskey sent above

[proud pebble]

turns out theres an event for when a command is sent, i wasnt aware of this.

[lyric gyro]

oof

[hoary scarab]

Well I don't know what the error was or what caused it exactly by I knew what portion of code caused it cause at the time I had just added it. So I modified the code and the error went away.

[lyric gyro]

Hey,
So how can I get every row from my MySQL table and return all rows in a String Array?

[tawny shore]

I have a question, is it possible to modify the enchantment table options?
for example add diamond sword and netherite and possible enchantments are custom

[lyric gyro]

I dont think you can. Altho you could use a Custom Interface

Wait

Maybe there is o.o

[lyric gyro]

take a look at this
https://www.spigotmc.org/threads/adding-custom-enchants-into-an-enchanting-table.378581/

[tawny shore]

oh thanks!
yes i thinked use enchantment table interface, i read that could change first slot that is where puts item and seconds slot that is where puts the lapis lazuli but i stayed with doubt if i could change the enchantments as options

[icy shadow]

Any idea how to do collision detection with a custom model data armorstand?

[high edge]

yikes

[icy shadow]

yeah lol

i guess i'll just require that the hitbox is configured manually with a boundingbox

because it's not like the server knows how big it is

[dense drift]

yea, most likely

[icy shadow]

or could read the blockbench format

and automatically configure it

[dense drift]

is probably easier to do it manually

unless it tells you the size

[icy shadow]

i think the resource pack format specifies it

            "from": [-13.3, 0, -1.23],
            "to": [29.3, 7.1, 3.03],
            "rotation": {"angle": 0, "axis": "y", "origin": [-3.36, 0, -3.36]},
            "faces": {
                "north": {"uv": [0, 0, 16, 8], "texture": "#0"},
                "east": {"uv": [0, 0, 4, 8], "texture": "#0"},
                "south": {"uv": [0, 0, 16, 8], "texture": "#0"},
                "west": {"uv": [0, 0, 4, 8], "texture": "#0"},

[ocean raptor]

does adventure's translatable components work on older versions than 1.12? (for items and blocks name) iirc thats when spigot added localized names

adventure doesn't translate components, it sends the translatable component to the client to render

that makes more sense

alright thanks

unrelated, but is

You can use a truth table to check stuff like this
https://trutabgen.com/ is a good online generator for truth tables

[dark garnet]

ohhh nice ive tried looking for one of those before tysm

[dull kayak]

Alright, I am lost.

This is the code that I have ```Java

    Bukkit.reloadWhitelist();
    //People that are whitelisted in the server file
    Set<OfflinePlayer> alreadyWhiteListed = Bukkit.getWhitelistedPlayers();
    Bukkit.getLogger().info("there are " + alreadyWhiteListed.size() + " players whitelisted");

And this is what it prints out:```
[INFO] .... there are 0 players whitelisted

While the whitelist.json file looks like this

[

    "uuid": "fac0a13c-91eb-43f7-894b-0d4483232af6"
  },

Why in the world does the getwhitelistedplayers method not work?

[spiral prairie]

when are you running the code

try to run it when a player joins

[tacit quail]

this if statement isnt working

whats wrong

    @EventHandler
    public void onEntityDamage(EntityDamageByEntityEvent e) {
        if ((e.getEntity() instanceof Animals && e.getDamager() instanceof Player) ||
                (e.getEntity() instanceof Monster && e.getDamager() instanceof Player) ||

            Player damager = (Player) e.getDamager();
            if (damager.getInventory().getItemInMainHand().getType().equals(Material.STICK)
                    && (damager.getInventory().getItemInMainHand().getEnchantmentLevel(Enchantment.KNOCKBACK) == (50))) {
                damager.getInventory().setItemInMainHand(null);

            }

        }
    }

full code ^^^

i just realised that code is extremely slow

[broken elbow]

what about it isn't working? where does it stop? have you tried debugging stuff? aka printing to console

also that if statement, can be made a lot shorter

[tacit quail]

when i actually hit anything in game it doesnt set to null

[tacit quail]

just realised im gonna improve it

[broken elbow]

check if damager is player only once

[tacit quail]

alrighty

[broken elbow]

start putting in debug messages

and see what code it runs, and what code it doesn't

[tacit quail]

alright ill check

why cant i do getLogger() in this class?

its an event handler

why cant i do that

pass the logger in the constructor from your JavaPlugin class

like this?

never tried to do this before

ok

nevermind this worked

i just needed to do Bukkit. before it

[icy shadow]

what makes you say that?

aside from the redundant instanceof checks (which arent really gonna be slow) it looks fine

[icy shadow]

using the bukkit logger is a bit of a bad practice, the best way is to either use your Plugin's logger with DI as blitz said, or make a logger for the specific class with Logger.getLogger / LoggerFactory.getLogger

[tacit quail]

for me slow = unoptimized

[dull kayak]

on a bukkit runnable. Each minute

[dense drift]

    sourceCompatibility = JavaVersion.VERSION_11
    targetCompatibility = JavaVersion.VERSION_17```
Does this mean it will be compatible with java 11? I can't remember which option is for that 😬

I need java 17 for paper 1.18.1 but the jar to be compiled with java 11

[stuck hearth]

source would be the JDK used to compile, so it would restrict certain language features.
eg: 1.6 couldn't contain any lambda expressions.

Target would be the version of the generated class files, and should denote the lowest Java version the program will run on.

[dense drift]

so I should just switch them?

    sourceCompatibility = JavaVersion.VERSION_17
    targetCompatibility = JavaVersion.VERSION_11```

Could not resolve: io.papermc.paper:paper-api:1.18.1-R0.1-SNAPSHOT I guess not 😐

[dusty frost]

I don't think it can go that way around

I think it can only up-compile source -> target

doubt it's a polyfill like javascript or somethin

[dense drift]

uh, that sucks

fucking paper, they have to do things in the right way all the time! spigot 1.18.1 is just fine with java 11

[dusty frost]

why do you need to target Java 11 anyways? You need Java 17 to run Paper 1.18.1

[dense drift]

1.13 compatibility, is for chatchat and we need some api from paper as an alternative for what spigot offers

[dusty frost]

oh I thought we were only supporting versions with hex colors

[dense drift]

nah, 1.13+

[dusty frost]

who the hell even runs anything besides 1.18 and 1.19

i will pull out bstats rn

[dense drift]

fc call

[dusty frost]

https://i.imgur.com/6zR8HWG.png

we would only be losing ~8%!

[dense drift]

idk man

[dusty frost]

And only ~17% if we only supported Java versions made in the last 7 years

[dense drift]

so.. is not possible to use paper 1.18.1 and java 11? 🥺

[dusty frost]

Oh no definitely not, they use Java 17 features in the code

[dense drift]

Time for some reflections🪞 then

[dusty frost]

what are you going to do for spigot servers?

[stuck hearth]

Reflect on your decision to support legacy debt 😌

[dense drift]

is not mine, ok ??

[dense drift]

I already have a check for paper & >= 1.16

[stuck hearth]

Things I didn't say

spigot will just use something that works there

final var prefix = material.isBlock() ? "block.minecraft." : "item.minecraft.";
return Component.translatable(prefix + material.getKey().getKey());```

so what do you get for being paper & >= 1.16

[dense drift]

Material#getTranslationKey

[dense drift]

but thinking about it, this might work anyways

[dusty frost]

I mean surely it's not worth using two systems that do the exact same thing

just use the one that works for all of em and call it a day until we bully fc into submission

[dense drift]

yup, will wait for a good reason

problem solved

Make a multi-version wrapping library 🙂

or just let legacy users use DeluxeChat!

Hi ppl

I want to start making plugins

Is there any tutorials for paper spigot 1.16.5

Placeholder API Dependency not working pls help

[orchid wyvern]

some code would be helpful to see what you've tried. How have you added the dependency, what are you trying to do with it etc.

[orchid wyvern]

Make sure you have a good understanding of java first. Haven't checked out tutorials in years, but when I've needed something on a particular topic, TheSourceCode on youtube tended to be good

It's all preference, some people learn better off purely text resources, some off youtube, some prefer to buy courses (although personally I'd stay away from them)

[merry knoll]

i would be careful with thesourcecode, they can be good on some topics but some of their tutorials have some really bad conventions

[orchid wyvern]

Like I said, haven't watched them in years, so I don't know what state they are in now

[merry knoll]

i would personally just set up the basics and jump into a basic plugin afterwards

[orchid wyvern]

@outer fulcrum how are you adding the dependency, maven/grade?

[merry knoll]

you will end up learning as you get stuck if you know how to google properly

[outer fulcrum]

yes

[orchid wyvern]

sending your config for that would be handy
