[smoky oak]

because if i set the upward velocity of a player WHILE they hold an item and right click (flight) if there's a 4 tick delay they just hop up and down

[lavish hemlock]

getOfflinePlayer should work for all players, as Player is also an OfflinePlayer

[smoky oak]

and i really dont want to do more static hashmaps

[misty ingot]

but I cannot kick an offline player value

I need to kick them after adding them to the bukkit banlist

[lavish hemlock]

player.isOnline() exists iirc

if that returns true, you can cast to Player

[misty ingot]

welp, time to rewrite all the code

[lavish hemlock]

or on newer versions of Java, you may also want to use pattern matching w/ an instanceof

e.g.

if (oplayer instanceof Player player) {
    player.kick();
}

(or something like that)

[misty ingot]

so If an offlineplayer returns as null, I can be sure to say that the player does not exist at all right

[smoky oak]

alternatively i could just run a task timer 3 times but idk if i can do that with an internal value. is it possible to get how often a task has been run?

[ivory sleet]

iirc Server::getOfflinePlayer yields a CraftOfflinePlayer regardless so best way to obtain the normal player would be with OfflinePlayer::getPlayer

(And null check obv)

[rough drift]

OfflinePlayer#hasPlayerBefore

[lavish hemlock]

Good to know.

[sharp flare]

a simple boolean condition can check that

using the method mentioned by the peeps above

[misty ingot]

I cannot check if an offline player has a certain permission, however I would like to check if they have the ban.exempt permission

[ivory sleet]

Vault API allows you to

[tardy delta]

Do they work with a database or something?

[ivory sleet]

Well VaultAPI is just a bridge

It offers a set of interfaces which any plugin can implement and provide

[quaint mantle]

Restart is like 2-3 seconds. I use run-paper gradle plugin to simplify debug

[trail pilot]

Damn

[lavish hemlock]

Not for me :p

[quaint mantle]

            ItemStack iron_sword = new ItemStack(Material.IRON_SWORD);
//            Enchantment enchantment = new Enchantment();
//            iron_sword.addEnchantment(null, 0);

does using addEnchantment really work?

[lost matrix]

You should use the ItemMeta regardless

[quaint mantle]

why do they have it then?

[ivory sleet]

Legacy probably

[lost matrix]

addEnchantment(null, 0) lul

[lavish hemlock]

Backwards compat is the cause of all evil

[grim ice]

uh

[quaint mantle]

We know right

[grim ice]

anyone can help test smth

[quaint mantle]

amogus

[grim ice]

actually nvm

[lavish hemlock]

Example: Want reified generics? Too bad, backwards compatibility.

[quaint mantle]

i want to help

[ivory sleet]

[grim ice]

u have to login mc tho

[quaint mantle]

my laptop cant even run mc

[lavish hemlock]

Speaking of Java, I really fuckin' want Project Valhalla to come out >:(

[ivory sleet]

Yeah, I’ll get a virtual orgasm once valhalla is out fr

[quaint mantle]

By the way how was I supposed to know I need to use ItemMeta?

[summer scroll]

@ivory sleet , I'm still struggling to save all of the nether portal blocks. https://paste.md-5.net/acuwenukuh.coffeescript

[ivory sleet]

Idk

[quaint mantle]

I didnt even know about that class till I googled how to add enchantments

[quiet ice]

good luck waiting

[ivory sleet]

Yeah torchun it’s not trivial at first

But now you know (:

[grim ice]

uhhh actually i still need someone to test with me

[quaint mantle]

please someone help Hex

i like his pfp

[ivory sleet]

Uh, can you provide some more code, or is that all?

[quaint mantle]

wait no way

[grim ice]

lol

[quaint mantle]

i just realized it

that is diamond armor

he made the diamond armor become sus

i can see it now

[summer scroll]

Maybe, there you go https://paste.md-5.net/focipuvoda.java

[misty ingot]

why is it showing with the red underline and a bunch of errors

I copied it as is

hao

oh I just did that

it worked thanks

I havent actually worked with any APIs before :p

[ivory sleet]

Cap

[smoky oak]

should i just launch a task three times with different delays or do a counter in it?

[ivory sleet]

I’d say the former

But if you want to keep the same task object the latter would suit you better

[smoky oak]

eh I really dont need it

the most complicated part is doing it so i dont actually write the code three times

[ivory sleet]

Ye

[smoky oak]

bc this far I'Ve been doing new BukkitRunnable(){@Override public void run{}}.runTaskTimer...

[ivory sleet]

Looks a bit compact but nice

[smoky oak]

of course i have line breaks in there

[ivory sleet]

🙏

[smoky oak]

i just dont know why to bother doing a BukkitRunnable object if i can just initialize and directly schedule it

[ivory sleet]

[summer scroll]

Does restoring the nether portal inside runTaskTimer will have different result or something?

[ivory sleet]

I don’t think so

But like what goes wrong specifically?

[summer scroll]

It only sets one block

With the current code that I have https://paste.md-5.net/focipuvoda.java

[smoky oak]

is .runTask(Plugin) equivalent to .runTaskLater(Plugin, 0) ?

[ivory sleet]

Yeah

[summer scroll]

runTask will run 1 tick after

[ivory sleet]

or if it was 1L

[summer scroll]

Wait, so If I store Block instead of BlockState, will the contents of the Block will be changed If I set the Block type to something else?

[ivory sleet]

Aglerr it’s a bit hard to figure what goes wrong as of now since I can’t test it for myself

Idr the implementation so can’t answer that but I’d assume so

What

[maiden mountain]

@summer scroll Probably no

[ivory sleet]

What’s wrong with BukkitRunnable

[maiden mountain]

I assume you're talking about changing the Material for example? @summer scroll

[summer scroll]

Yes the material

[maiden mountain]

Then the Block stored in the list will change automatically

[ivory sleet]

That’s false

[maiden mountain]

Reference Types 🙂

[ivory sleet]

BukkitRunnable allows you to derive it and still offers its instance methods imperatively

Which would be a real hassle to deal with if you simply stick with Consumer<super BukkitTask> and the BukkitScheduler

[summer scroll]

Okay thanks, just what I thought.

[smoky oak]

god fucking dammit
java.lang.IllegalStateException: Already scheduled as 173
I can't use the same instance

[maiden mountain]

Unless you create an entire new Block class, the block that's stored will just change along since that's how Reference Types work 🙂

[quaint mantle]

I was doing leather_helmet_meta.getItemMeta() and I was wondering why im not getting the method till I realized what variable I was using. Is this the kind of stuff that happens to you guys?

[smoky oak]

aaaaand it doesnt even have a clone() function urgh

[summer scroll]

Yeah, basically I'm modifying and storing the same object

[maiden mountain]

Yep since they are both references to the same object

[ivory sleet]

Moterius you’d either use a runTaskTimer or schedule a new BukkitRunnable instance inside the callback itself

Either two are fine (think we went over it alr)

[smoky oak]

well i want it to trigger exactly three times and im unsure how to count that

also i have yet to hear an answer to the question if i can see how often a task was executed already

[ivory sleet]

It’s possible to implement that

If it’s only concerning runnables of your own

[smoky oak]

ah

i guess doing a counter in a class implements BukkitRunnable, then setting that counter on creation, and just doing if(i++>3) cancel()

[ivory sleet]

Hmm

Yeah

Might work

[smoky oak]

anyone knows why it doesnt show an error while i am trying to define a class inside a function?

[ivory sleet]

Doesn’t show an error?

Idk maybe share the code

[lost matrix]

Because its valid java

[smoky oak]

so any reason why i shouldnt? (Excluding scope?)

[lost matrix]

Because it will most definitely lead to unreadable code.

[smoky oak]

i found a completely different issue lol

it cant see that class

maybe i need to put it above?

yup

[summer scroll]

How can I get all locations of nether portal block from one location?

[lost matrix]

flood filling algorithm

[summer scroll]

This is what I tried https://paste.md-5.net/ezevopuroh.cs but can only get 3 blocks, which is self, up, and down.

[smoky oak]

repeat on all newly found portal blocks until you no longer find new blocks

[tardy delta]

Why creating class in a method lol

[smoky oak]

class only needed in method

[tardy delta]

And not just an inner class

[smoky oak]

we need a runTaskTimer(Plugin, task, delay, period, count) function

[tardy delta]

I would still create an inner class

👀

[summer scroll]

I already called the method again If the nether portal is found, but I think the problem is on the blockface.

[smoky oak]

🤷‍♂️

havent worked much with algorithms like that

one time i tried i gave up and did something else

[misty ingot]

so I tried getting permissions of offlineplayers using the VaultAPI but even that shows errors lmao

I have the latest version of the API i.e. 1.7.1

[smoky oak]

doesnt it need a player object?

[lavish hemlock]

I believe you need to pass the world as well to use an offline player

public boolean playerHas(String world, OfflinePlayer player, String permission)

[lavish hemlock]

Also, has is (mostly) deprecated

[misty ingot]

which one

[lavish hemlock]

The two that are deprecated lol

[misty ingot]

I am using the top one

[lavish hemlock]

You need to use playerHas

[lavish hemlock]

.

[misty ingot]

the world of who

[young knoll]

(Player already extends OfflinePlayer)

[lavish hemlock]

Actually wait yeah why are you doing player.getUniqueId()?

[young knoll]

You don’t need to create an offline player instead at all

[misty ingot]

I just realised how dumb my brain becomes after I have been awake for 21 hours

[lost matrix]

https://gist.github.com/Flo0/588b0b53e6c150065677c0c544a33f11
🥣

[misty ingot]

note the part where it says that it does not return an object for offline players

my brain is on fire

[lavish hemlock]

I mean it is "may not"

but idk wording is confusing

[misty ingot]

well it doesnt do it

so

yeah

I just need a way to check permissions of a player regardless of them being online or offline

oh and to check if they are isBanned()

[young knoll]

Then get them as an OfflinePlayer

[misty ingot]

now thats where the issue comes in

[quaint mantle]

its time for me to learn generics

[misty ingot]

I cannot get the permissions for offline players even when using VaultAPI for some reason

I am either very very dumb or I am very very dumb

[mortal cedar]

Is there a way to let players interact e.g. hitting entities outside of the world border?

[visual tide]

get ur perms object from the registeredServiceProvider then use perms.has(offlinePlayer, permission)

[summer scroll]

Thanks, may I ask why my current method doesn't work? https://paste.md-5.net/zupaluqaci.cs

[misty ingot]

Already am I think

also has() does not work with offline player object

[visual tide]

that looks correct

hm

sec

[misty ingot]

yeah I because I got it straight from their github instructions thing

[smoky oak]

can i no longer do Integer.maxValue() ?

[devout solstice]

Hey can anyone help me with a plugin that I want to make for a manhunt video for my friends channel you can @ me if you want to

[summer scroll]

Integer.MAX_VALUE it's a field.

[visual tide]

 /**
     * Checks if player has a permission node.
     * Supports NULL value for World if the permission system registered supports global permissions.
     * But May return odd values if the servers registered permission system does not have a global permission store.
     * 
     * @param world String world name
     * @param player to check
     * @param permission Permission node
     * @return Success or Failure
     */
    public boolean playerHas(String world, OfflinePlayer player, String permission) {

[smoky oak]

nope

[visual tide]

in caps

[smoky oak]

oh wait

yea i just realized that too

different topic, what's the event that happens when a player drinks milk and erases their effects?

[misty ingot]

can I have a link to that doc plz

[summer scroll]

PlayerItemConsumeEvent iirc

[smoky oak]

imma try thanks

[young knoll]

PlayerItemConsumeEvent or EntityPotionEffectEvent

The later has a cause for milk

[visual tide]

its javadocs in the code 😐

just ctr click on the method

https://github.com/MilkBowl/VaultAPI/blob/master/src/main/java/net/milkbowl/vault/permission/Permission.java

ig

[tardy delta]

whats the difference between CompletableFuture#whenComplete and CompletableFuture#thenAccept

#thenAccept returns a CF<Void> where whenComplete returns a CF<T>

[quaint mantle]

whenComplete also handles exceptions

[lavish hemlock]

Hey, how do I convert hours to ticks?

[smoky oak]

*60 *60 *20

also

EntityPotionEffect e
(e.getAction() == EntityPotionEffectEvent.Action.ADDED) && (e.getNewEffect().getType == PotionEffectType.POISON)``` returns false - I'm not having any effects and using a poison splash potion

[quaint mantle]

Duration.ofHours(hours).toMillis() / 50

[tardy delta]

💀

[tardy delta]

im making a home command and im keeping a homes cache for each user, is it bad to save a newly created home on the database immediately?

and then putting it in the cache

[next stratus]

Hi, I'm using the events from here https://teamvk.github.io/AutoSellAPI/javadoc/me/clip/autosell/events/package-summary.html but IntelliJ keeps saying that the plugin can be a record is it bad to make a listener class a record?

[tardy delta]

a record will expose all its fields

[next stratus]

So is it worth making it a record then?

[quaint mantle]

So, I want to fix a player's camera rotation. The player can't move the camera. And no, I don't want the... what should I call it?... I don't want the jitter effect when trying to move the camera that is achieved by constantly teleporting the player. My idea is that I can switch the player to spectator mode, and make the player go into a mob. The mob has no ai or gravity, and the player can't rotate the camera. Would this work?

[tardy delta]

if you want to have a getter for all of your fields you can consider making it a record

fields are also final

[visual tide]

pretty sure yes but use an item frame or armorstand as entity

instead of a mob

[quaint mantle]

Ah okay

[next stratus]

Oh I might do it then that seems useful

[quaint mantle]

Is there a method that sets what entity the player that is in spectator mode viewing as?

[visual tide]

https://www.spigotmc.org/threads/spectate-player-entity.41756/

[quaint mantle]

alr thanks

[tardy delta]

for example if you have a field test the getter will be named test() instead of getTest()

[next stratus]

hm, that's interesting

Sorry, i've not used records before aha

[quaint mantle]

A quick question, can multiple players view as the same entity?

[visual tide]

yeah

[quaint mantle]

alr thank you

[grim ice]

damn i should call my fields

getTest then

/j

[tardy delta]

?

[smoky oak]

@tardy delta I've taken to saving my cache only when a player leaves or the plugin gets disabled

[tardy delta]

what if the server crashes lol?

[smoky oak]

not too big an issue

[visual tide]

ServerCrashEvent 😄

[grim ice]

plugin ondisable is called on crash isnti t

[smoky oak]

rejoining resets almost all variables in my plugin

[visual tide]

no

[smoky oak]

but still

[visual tide]

if the server crashes it crashes

= ded

[smoky oak]

can someone explain this?

why is it the second i actually want to know somethign this server is just DEAD

[tardy delta]

what event is that?

[smoky oak]

the event when a potin effect gets added or changed (or reset via milk)

[tardy delta]

can i see the whole code?

did you even register it lol

[smoky oak]

I did

i know that because if i send a log message right before that if clause up there it shows up in the logs

[quaint mantle]

No, it is not bad

I do it like this

[smoky oak]

?paste

[undone axle]

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

[tardy delta]

searching thro the github repos

[smoky oak]

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

[tardy delta]

whats that Echo thing lol

logger i guess

[smoky oak]

ye

[tardy delta]

// handle milk kekw

[smoky oak]

i have code there but its not relevant

the other comment is the one you should read

[tardy delta]

i dunno

is this actually a comment or did you just set it as a comment for now?
// && Echo.hasTrait(player, trait_enum.PASSIVE_POISON_IMMUNE)

[smoky oak]

for now

iirc that ALSOdoesnt trigger

[tardy delta]

well then isnt that your issue?

[smoky oak]

probably

still

[tardy delta]

have you tested it with only the effect type check?

[smoky oak]

I think so. i cant do it rn but i think that one also doesnt work

@tardy delta can i ping you later when i have time?

[tardy delta]

ye

[smoky oak]

k thanks

ttyl then

[grim ice]

https://github.com/2Hex/EntitySerializer

code review

thx

[tardy delta]

THIS IS NOT FOR YOU. :(

[grim ice]

lol

I mean

how else do i stop them from using the method

well im only doing that in the main class

but in everything else

you only use classes inside api package

[mellow edge]

how to stop the server with spigot

?

[eternal oxide]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/Bukkit.html#shutdown()

[mellow edge]

that was the command lol

I tought it is Bukkit.stop();

[lost matrix]

System.exit() XD

[grim ice]

Bukkit.getServer().shutdown()

oh nvm elgar alr sent it

[mellow edge]

"YEA system.exit would defenetly be good"

here code

sorry for bad england (XD)

[smoky oak]

why are you using SQL anyways? Can't you store stuff like that in configs or PDC?

[trail pilot]

my plugin have config storage

but an dude said to use databse

[chrome beacon]

Looks like you're trying to create a column that already exists

[trail pilot]

OH

uhm

[manic delta]

someone knows about luckperms api?

[chrome beacon]

Yes

[manic delta]

Can you help me

[trail pilot]

public void setPlayerHome(String homeName, Player player) {
        plugin.sqlite.getResultSet( "INSERT INTO '" + plugin.database.table +"'(player, home, x, y, z, world_name) VALUES ('" + player.getUniqueId() + "','" + homeName + "','" + getPlayerLocation( player ).getX() + "','" + getPlayerLocation( player ).getY() + "','" + getPlayerLocation( player ).getZ() + "','" + player.getWorld().getName() + "');");
    }```

[manic delta]

I just want to get user rank

[trail pilot]

so tf should i use?

[manic delta]

[trail pilot]

[lost matrix]

Dont use databases or files like that. You should keepe everything in memory and only use SQL for data storage when a player disconnects for example.

[trail pilot]

😭 i dont understand what you mean

[smoky oak]

writing and reading files is slow

he's saying to keep it in memory until the player leaves or the server stops

[trail pilot]

yea that i know

[trail pilot]

how How HOw HOW

[smoky oak]

variables?

use hashmaps

[grim ice]

why do u have sqlite field there

make a class for Storage

[rough drift]

daaaaaaaaaaam

[grim ice]

or make an auto save

[rough drift]

could've used a string builder there

[trail pilot]

i think the best option is

[grim ice]

every 10 minutes, on another thread access the database

and write

from the hashmap

however u might wanna distribute it

[trail pilot]

should be cool

[grim ice]

not sure, ask someone else

[chrome beacon]

https://luckperms.net/wiki/Developer-API-Usage#finding-a-players-group

[trail pilot]

but i have really basic knowledge LEL

[grim ice]

who cares

[trail pilot]

me

[grim ice]

if u just dont do anything

[trail pilot]

because im the one who cries if something is broken

[grim ice]

cuz ur level is low

u wont learn

[manic delta]

Thanks olivo

[grim ice]

use version control?

[rough drift]

olivio oil

[grim ice]

so if u break ur code u can restore it

[smoky oak]

lp user <user> info shows permissions and groups

[trail pilot]

..?

[rough drift]

github

alot alot of github

[trail pilot]

yea i use it

so tf i need to do?

[rough drift]

Use a, Use a, use a string builder!

[trail pilot]

tf is a StringBuilder?

[rough drift]

better way of handling strings

[eternal oxide]

Use a PreparedStatement

[trail pilot]

i only know how to set an instance

and print things in console

[rough drift]

StringBuilder sb = new StringBuilder();
sb.append("a");
sb.append("b");
```Allows you to replace the +

looks cleaner

[trail pilot]

yes i got it

and then?

[rough drift]

then sb.toString() to get result

[hardy swan]

please use prepared statements

[rough drift]

instead of your messy "abc" + a + "dfg" etc

[quaint mantle]

MessageFormat.format() tho

[trail pilot]

...

[quaint mantle]

Prepared Statements is a way to go yes

[trail pilot]

Ok

[trail pilot]

sb.append( "('" ).append( player.getUniqueId() ).append( "'," );

like that is ok?

[rough drift]

yeah ig... just, why the spaces?

[trail pilot]

ask ij idea

lol

[quaint mantle]

Use prepared statements
Use prepared statements
Use prepared statements
Use prepared statements

[rough drift]

wdym it works fine for me

[rough drift]

also this

[trail pilot]

i mean its make automatically like that lol

[trail pilot]

hOw?

where

when

[quaint mantle]

Read any jdbc guide

[trail pilot]

[glossy venture]

prepare a statement, clone it and set the values

then execute it

put a ? where you want to insert the values

like SELECT * FROM my_database WHERE id = ?

and then to set it do statement.set...(position, value)

[manic delta]

some java regex expert?

i want to convert &c&lAdmin&7 :&f to Admin (Just need the string)

forgot i just will use group name

[lost matrix]

Sounds like an xy problem

[manic delta]

forgot

[lost matrix]

Why do you want to do this?

[manic delta]

i will use group name instead

[manic delta]

im doing jda bot

[grim ice]

https://github.com/2Hex/EntitySerializer pls bully me with code reviews

[manic delta]

using spigot

but i will do it with the group

[grim ice]

I wanna improve anything possible

[glossy venture]

ChatColor.stripColor(...)

[manic delta]

forgot

i will use play group name

[glossy venture]

o

[manic delta]

u

[glossy venture]

k

[trail pilot]

OHH

i got it!

[glossy venture]

nice

[hardy swan]

it is important to understand why you should use PS, to guard against sql injection

[vale frigate]

Hello yall! I have a problem using nms. I need it for NBT modification. now since everything got changed I have no idea how to get the nms classes into my workspace. I only added the spigot api to my project with maven since everything else did not work for me, does someone know a solution?

[tacit drift]

NBTApi

a good api

no need for nms

[vale frigate]

Sure? I need to add CanBreak and CanDestroy tags to some items. Does it provide that?

[lost matrix]

The main benefit of prepared statements is that they dont need to be recompiled

[tacit drift]

yes

i just did that in my plugin

it's just 3 lines of code

NBTItem pickaxeNBT = new NBTItem(pickaxe);
NBTList<String> tags = pickaxeNBT.getStringList("CanDestroy");
tags.add(canDestroyTag);

canDestroyTag is something like "minecraft:redstone_ore"

[vale frigate]

Oh okay, thank you! So you did not "import" nms right? I am actually wondering on how to do that... I mean, I know we should avoid NMS but I am still wondering why it isnt working... But thank you! Really appreciate that!

[tacit drift]

no nms

either put the api as a plugin on the server

either shade it

check the wiki for more info or join their discord

[vale frigate]

Oh okay, I'll give it a try.

Thank you!

[smoky oak]

whats the latest spigot version?

[lost matrix]

yes

[quiet ice]

1.18.2-R0.1-20220301.213937-3

[smoky oak]

thanks

whats the arg for remapping? I cant find it on the spigot page

[lost matrix]

--remapped i think

[smoky oak]

thanks

[sage dragon]

I saw there's a broadcastChanges method in PlayerChunk, is there a way to get PlayerChunk from a chunk?

[lost matrix]

The heck is a PlayerChunk?

[sage dragon]

I have no idea 😅

[lost matrix]

Its def nothing api related

[sage dragon]

I just saw this class when I tried fixing something...

[viral crag]

you sure that is not from some other api?

[sage dragon]

Oh, it's nms 😅

[smoky oak]

uh using latest as version arg compiles 1.18.1

[quiet ice]

that is because 1.18.1 is latest stable release

[smoky oak]

ah

[quiet ice]

1.18.2-R0.1-20220301.213937-3 is the latest maven release (you should really use 1.18.2-R0.1 though)

[grim ice]

my EntitySerializer library now works, yay

[lost matrix]

What if 2 entities stand at almost the same location? So in each other?

[boreal sparrow]

im dumb whats wrong with this?

        p.sendMessage(player +  " has left the call, no amaswidis for them...");
    }
}

} i have 0 idea what im doing ._.

[grim ice]

hmmm

theres no fix for that

[lost matrix]

Object player = event.getPlayer(); < - ???

[boreal sparrow]

._.

[quiet ice]

A var a day makes your life easier

[lost matrix]

Did you register the listener?

[boreal sparrow]

true

[quiet ice]

I believe he gets an output like "org.bukkit.Player@145466 has joined and gets"

[lost matrix]

    @EventHandler
    public void normalLogin(PlayerLoginEvent event) {
        Player player = event.getPlayer();
        for (Player online : Bukkit.getOnlinePlayers()) {
            online.sendMessage("Ubrandon (aka " + player.getName() + ") has joined and gets amaswidis");
        }
    }

[boreal sparrow]

y

ty

[grim ice]

WAIT

maybe i should do smth

to liek

[tardy delta]

sorry for bad england

[lost matrix]

tp the copied entity to a safe location first.

😄

[grim ice]

get the entity

o

that makes sense

but what location

oh do i spawn it

in the sky

[lost matrix]

Idk. Try something at ~ 3000 ~
So just up. This way you dont need to load any new chunks.

[grim ice]

yeahh

genius :o

[boreal sparrow]

lol that doesnt work it doesnt do anything when they join weird

[lost matrix]

Did you register the listener?

[boreal sparrow]

u mean public class LoginListener implements Listener

[grim ice]

no

[boreal sparrow]

._.

[grim ice]

ok he didnt register it

[boreal sparrow]

yes

[grim ice]

then register it

https://www.google.com/search?q=how+to+register+a+spigot+event&oq=how+to+register+a+spigot+event

[boreal sparrow]

i did that sry im dum

[ivory sleet]

?event-api

[undone axle]

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

[boreal sparrow]

in min class

weird

[grim ice]

show how you did it

also r u using eclipse

u prob are

[boreal sparrow]

just found smh weird

other ppl can see the message

u cant

wasting my time for ~20 minutes

[grim ice]

@lost matrix But if i spawn it at the sky

then tp to the ground

it will take damage

wont it

ill have to set it to invincible

[past vapor]

How can i get the direction of a sign

[lost matrix]

Not really. The damage is directly proportional to ticksInAir

[lost matrix]

I think the BlockData is Rotatable

[past vapor]

Only a wallsign

[lost matrix]

get the BlockData and cast it to Rotatable or Sign

[lost matrix]

no

[quiet ice]

what has that to do with their issue

[lost matrix]

WallSign is Directional not Rotatable

[lost matrix]

here comes the eclipse police

[quiet ice]

yes, that is what the code is doing (and from my perspective is what it should do)

I see no issue there

[boreal sparrow]

ye maybe but onlineplayers... shouldnt that include the one who has logged in just now?

[quiet ice]

Oh, yeah the player that joined isn't considered online at that point

[boreal sparrow]

damn

[quiet ice]

You'd need an extra line of code to also include the joining player

[boreal sparrow]

ok

[quiet ice]

Similarly dead players will not recieve the message or something like that

[boreal sparrow]

ooh

[quiet ice]

It is better to use Bukkit#broadcast

[boreal sparrow]

thats the thing

i also used that

same issue

[quiet ice]

?jd-s

[undone axle]

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

[boreal sparrow]

thats why i fell back to onlineplayers in the first place

[smoky oak]

... ... ... ... ...
screw this game.

player.sendMessage((newEffectType == PotionEffectType.POISON)+""+e.getNewEffect().getType()));```

[quiet ice]

You could use https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/player/PlayerJoinEvent.html#setJoinMessage(java.lang.String)

[boreal sparrow]

oh come on XD

ty

welp maybe i should read docs nect time

[lost matrix]

PotionEffectType is not an enum

[boreal sparrow]

bruh docs are like chinese how do i use setjoinmessage

[quiet ice]

event.setJoinMessage("This is the join message");

[smoky oak]

googling for how to compare potion effect type bukkit results in 0 websites
how do i do it then

[lost matrix]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/potion/PotionEffectType.html#equals(java.lang.Object)

What do you use to compare objects on equality which are not a primitive or enum?

[smoky oak]

because im used to it from block#gettype

also anyone knows when 1.18.2 will be stable?

[quiet ice]

For newcomers the documentation can be complicated

[quiet ice]

?eta

[undone axle]

There is no ETA. Having an ETA leads to unrealistic deadlines, false hope, and a bad product. It will be ready when it's ready.

[lost matrix]

== -> equality if primitive or enum. Identity for objects.
.equals() -> equality for objects.

[quiet ice]

== is always identity

[smoky oak]

well that solved that problem

[quiet ice]

Enums just happen to be singletons

[lost matrix]

right. Just wanted to differentiate

[ivory sleet]

Generally

a == b -> true then a is b
a != b -> true then a is not b

[quiet ice]

Yeah, you should use == for enums either way. Whether it is equality or identity does not make a difference there. (though using .equals() will lead to fail-fast behaviour if the left argument is null)

Probably, though I'd avoid PlayerLoginEvent because it isn't async

it should be deprecated either way

[ivory sleet]

Well first we have PreLogin which is the blocking part (thus it’s invoked async), then we have Login which is post PreLogin and more data is established, for the Join, even the player entity is fully established.

[lost matrix]

You could still nitpick that phrasing because
a == b does not mean that a is b but that a and b point to the same memory address.

[smoky oak]

is there an api method to check if a entity stands in sunlight?

[ivory sleet]

I mean smile they’re the same

That’s the semantic specification

[quiet ice]

probably via heightmaps

[smoky oak]

heightmaps?

[ivory sleet]

Because we treat, for all b and a, b and a are values

[quiet ice]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/HeightMap.html#OCEAN_FLOOR

[ivory sleet]

@quaint mantle

[lost matrix]

They are not the same. If they where the same then

int a = 10;
b = a;
a = 20;

Would mean that a and b would then both point at 20. But b will point at 10.

[ivory sleet]

You’re mistaking me

I am not involving any variables

[smoky oak]

is glass a solid block?

[ivory sleet]

I’m simply stating that if a is b then a == b is true and vice versa, thus if a == b then a is b

And we’re inferring that for all a and b, a and b must be values

[smoky oak]

it is

[quiet ice]

Oh right. Then use https://hub.spigotmc.org/javadocs/spigot/org/bukkit/block/Block.html#getLightFromSky()

Completely forgot transparent blocks existed

Material#isTransparent might be one, but that one is deprecated

[lost matrix]

If a and b are referring to values then this is a weird example because you cant directly compare them in java.

[boreal sparrow]

cannot resolve method eventsetjoin message in playerjoinevent this is proboply a very dumb question but seriously whats wrong

[lost matrix]

Show your code

[quiet ice]

You forgot the dot

[boreal sparrow]

@EventHandler
public void normalLogin(PlayerLoginEvent event) {
event.setJoinMessage("This is the join message")

[lost matrix]

lol

[boreal sparrow]

god damnit

[quiet ice]

Unlikely. Paper probably has a way of resolving the transparency via Starlight however

[smoky oak]

public static HashMap<UUID, Set<BukkitRunnable>> runningTasksPerPlayer;
    public static void listTask(UUID id, BukkitRunnable r){
        runningTasksPerPlayer.get(id).add(r);}

would calling listTask add the task to the set inside runningTasksPerPlayer, or to a copy?

[lost matrix]

Dont make it public. And its stateful. So dont make it static either.

[smoky oak]

which answers the question not

[quiet ice]

Either it throws an exception, or add

[lost matrix]

In the map there is a Set object stored. Your method gets that Set and adds an object to it.

[quiet ice]

It will not create any copy

[smoky oak]

ok thanks

[quiet ice]

Probably not what you want

[tall dragon]

True or false 👍

[quiet ice]

Given that I'd say that it returns false for Glass for example

?stash Actually, let'S find out for sure

[undone axle]

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

[quiet ice]

https://hub.spigotmc.org/stash/projects/SPIGOT/repos/bukkit/browse/src/main/java/org/bukkit/Material.java#5281

For determining transparency it's either nms or the material enum

That being said - there is a material enum refector in the works, so using the deprecated method is probably "good enough" for the meantime

Add what?

You could just hardcode the transparencies, but that would amount to just being Material#isTransparent

?jd-s

[undone axle]

If this issue is of no concern, yea, go ahead

[viral crag]

transparency is a texture and clientside render ...

[grim ice]

?paste

[undone axle]

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

[quiet ice]

It is also serverside

[grim ice]

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

tips to improve?

easter egg

and it doesnt matter the numbers

[quiet ice]

what the hell...

What is that method supposed to do?

[grim ice]

well

would make more sense

1s

that class is returned

[viral crag]

yes that is how the transparent or see through portals work

[grim ice]

after deserializing a serialized entity

and with spawnAndGet()

[quiet ice]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/RegionAccessor.html#spawn(org.bukkit.Location,java.lang.Class,org.bukkit.util.Consumer) that method already returns the entity however

Plus you can teleport it to a location outright...

[grim ice]

o

[grim ice]

nah

im not spawning an entity

im placing a structure

then retrieving the entity

spawned with it

[quiet ice]

Then I'd just pass a List to the spawn method were all the entities are put into

[grim ice]

wdym

[quiet ice]

Or make the spawn method return the entity outright

What even is the spawn method?

[grim ice]

public void spawn(Location loc) {
structure.place(loc, true, StructureRotation.NONE, Mirror.NONE,
0, 0f, new Random());
}

[quiet ice]

oh yeah, that makes things difficult

[grim ice]

better than using nms tho

or maybe not but still

[quiet ice]

I'd still not use streams, but I think that is the best you can do

.min((e1, e2) -> (int) (e2.getLocation().distanceSquared(location)
                        - e1.getLocation().distanceSquared(location)));

Also, this is asking for trouble. What if e1.getLocation().distanceSq is greater than e2.getLocation().distanceSquared?

dangerous

It will probably lead to artefacts if minecraft's lighting system is still as fragile as I remember it

how do i get a player's name that isnt weird and full of craftbukkit crap

ty

[quiet ice]

Well it will be not equal to the upper light level if it isn't transparent

0 means no daylight

(also beware that this method breaks at night)

0 is no light at all

[humble heath]

how would be the best way to kick a player as kickPlayer is now depricated

[opal juniper]

are you using paper

[wary harness]

any one has idea how this works

so it pops and rotates like 3d text

[humble heath]

i am using paper

[wary harness]

and item

[opal juniper]

there you go then

that’s why

they use adventure

[grim ice]

texture pack possibly

[wary harness]

just found out

[grim ice]

its a totem

retextured

[wary harness]

it is an totem

yep

xd

but cool

[grim ice]

lol iits not that hard to figure out

[wary harness]

well didn't play that much

from like 1.9

[boreal sparrow]

can i use an if statement with pname witha string to check for specific player in the event?
Player player = event.getPlayer();
var pname = player.getName();

eg. if(pname == "name"){

ty

[grim ice]

equals will not check for cases

"Diamond".equals("diamond") returns false

[wooden fable]

equalsIgnoreCase

[grim ice]

however "Diamond".equalsIgnoreCase("diamond") returns true

and dont do checks with player names for most of the time

you wanna use uuids

[boreal sparrow]

prob

if their user changes

[wooden fable]

How do I set the result of a PrepareAnvilEvent to nothing?

  event.setResult(null);
  event.setResult(new ItemStack(Material.AIR));

This is what I've tried and both don't work.

[sage dragon]

Does PacketPlayOutMapChunk send the blocks of a world when a player connects?

[visual tide]

is your event registered

[wooden fable]

ofc

[grim ice]

my library is officially done now :D

https://github.com/2Hex/EntitySerializer

i still need code reviews

[viral crag]

setResult(Event.Result newResult) Sets the result of this event. how about a proper result: https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/Event.Result.html

[grim ice]

How about proper research?
https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/inventory/PrepareAnvilEvent.html#setResult(org.bukkit.inventory.ItemStack)

[viral crag]

sounds good, how did we jump to anvils?

[grim ice]

Read

this

??

[wooden fable]

Ik

[viral crag]

i am going with teh stated event.setResult()

[wooden fable]

But how can i set the result to nothing, so the rightslot will be null?
https://i.imgur.com/ZKs2Bi8.png

[brave sparrow]

The left slot isn’t the result

The right slot is

[wooden fable]

oops of course haha

[raw ibex]

How would I send a 5 4 3 2 1 respawn countdown on the screen?

[grim ice]

get the inventory

and then get teh slot

a second ive made a plugin with anvils before

ill give you some basic code

[viral crag]

PrepareAnvilEvent is not event

[brave sparrow]

Run a timer, every second display the remaining countdown

[boreal sparrow]

how to play sound to all online players ._.

[viral crag]

gl with that

[grim ice]

what r u saying bro

[brave sparrow]

Wdym good luck, it’s literally a documented event

Are you high?

[brave sparrow]

iterate through all the players and play the sound to them

[boreal sparrow]

[ivory sleet]

?scheduling might be to your help

[undone axle]

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

Like this?

[grim ice]

well not 3

[brave sparrow]

Probably 2

[grim ice]

its 2

[brave sparrow]

Counting starts at 0

[wooden fable]

Oh yes of course...

[boreal sparrow]

can someone give me the command to play a sound to bukkitgetonline players

[grim ice]

setResult shouldve worked though

thats weird

[wooden fable]

That still doesn't work tho

[viral crag]

no

[brave sparrow]

Can you put a debug statement in your listener

So we can make sure it’s being called

[wooden fable]

Done, it is being called

    @EventHandler
    public void onPrepareAnvil(PrepareAnvilEvent e) {
        final ItemStack result = e.getResult();
        final ItemMeta meta = result.getItemMeta();

        if(!shouldCheck(e.getInventory())) return;
        if(!isMending(meta)) return;
        if(!isArmor(result)) return;
        e.getInventory().setItem(2, null);
        log("Called");
    }

[grim ice]

ur tryna stop mending?

then u dont need that

well u kinda do but

u can do a workaround for it

[wooden fable]

How?

That would be great

but only on armor

[grim ice]

Inv click event

[hasty prawn]

Delay the setItem call by 1 tick?

[brave sparrow]

I’m still interested in why this doesn’t work

[brave sparrow]

That’s how you make exploits lol

[hasty prawn]

Well but if the inventory isn't updated when the event is called then you're setting nothing to null

[grim ice]

e.setCancelled() if the slot is 2 and the inv type is anvil @wooden fable

[hasty prawn]

Because the result isn't there yet

[boreal sparrow]

physically why cant i do this:
Bukkit.getWorld("world").playSound(0, Sound.ENTITY_ENDER_DRAGON_GROWL, 1000000000, 1);

[grim ice]

bruh

[wooden fable]

I'll try that later today

[grim ice]

100000000?

[worldly ingot]

Don't use Inventory#setItem() in a PrepareAnvilEvent

[boreal sparrow]

it needs to go far lol

[wooden fable]

I'll send an update

[grim ice]

u wanna kill their ears??

[worldly ingot]

Use the event's setResult() method

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/event/inventory/PrepareAnvilEvent.html#setResult(org.bukkit.inventory.ItemStack)

[brave sparrow]

@wooden fable give me one sec I’m gonna figure out why setResult doesn’t work for you

[wooden fable]

That doesn't work to

[grim ice]

It didnt work

[brave sparrow]

They tried, it wasn’t working

I’m checking the spigot code now

[grim ice]

eitherway just use the workaround i talked about earlier if u cant find another solution

[worldly ingot]

Yeah if it doesn't work then either the snippet is doing something wrong or there's a bug that should be reported on the JIRA

Or another plugin is overriding it

[grim ice]

time to contribute! (jk i dont have an idea on how to do that)

[brave sparrow]

public static PrepareAnvilEvent callPrepareAnvilEvent(InventoryView view, ItemStack item) {
PrepareAnvilEvent event = new PrepareAnvilEvent(view, CraftItemStack.asCraftMirror(item).clone());
event.getView().getPlayer().getServer().getPluginManager().callEvent(event);
event.getInventory().setItem(2, event.getResult());
return event;

[boreal sparrow]

no volume makes it go further not actually makes it louder

[brave sparrow]

The spigot code appears to be correct

Very strange indeed

[grim ice]

still

if the volume is an integer

[hasty prawn]

Interesting

Hey but look I was right about the result being set after 😛

[grim ice]

nvm

[brave sparrow]

I figured you were

But it’s super weird that setResult isn’t working

[hasty prawn]

You're right though I forgot about the exploits

That is odd

[boreal sparrow]

am i dum or smh becuase what
Bukkit.getWorld("world").playSound(0, Sound.ENTITY_ENDER_DRAGON_GROWL, 100000000, 1);

[brave sparrow]

@wooden fable do you have any other plugins on?

[hasty prawn]

Let me see if it works for me

[brave sparrow]

It’s cause I have to deal with morons spending all day finding exploits

So I have to think about it

[hasty prawn]

LOL fair enough

[brave sparrow]

There’s one they found once where if they spam the keyboard and spin around and open the inventory it lets them dupe

All kinds of nonsense

[grim ice]

well duh

[ivory sleet]

Sounds like some sort of cult at this point lol

[grim ice]

ur location arg is "0"

[worldly ingot]

Works fine for me

[boreal sparrow]

ye but what should it be like what

[worldly ingot]

So you have another plugin overriding it

[boreal sparrow]

0 0 0?

[hasty prawn]

wtf

[grim ice]

anyone free to rate code

https://github.com/2Hex/EntitySerializer

[wooden fable]

Ye

[raw ibex]

How do I display?

[brave sparrow]

Make your event priority MONITOR just for a minute, let’s see if it works for you

You can’t leave it as MONITOR but it’ll be good to check

[brave sparrow]

As a title presumably

[boreal sparrow]

what should i put in coords?
Bukkit.getWorld("world").playSound(????, Sound.ENTITY_ENDER_DRAGON_GROWL, 100000000, 1);

[hasty prawn]

Where you want the sound to play

[boreal sparrow]

0 70 0

[raw ibex]

I basically want it to show in the middle of the screen, what function should I use

[boreal sparrow]

(middle of map sorta)

Whichever function in Player shows a Title

new Location(Bukkit.getWorld("world"), 0, 70, 0) then. Although your world should probably be obtained some other way than using getWorld since that can return null.

[brave sparrow]

No worries

[hoary pawn]

so it would be enught to just put "this" in refering to your main class, if the code was in the main class

[grim ice]

yeah

it just needs ur plugin instance

[viral crag]

if they are using event, they can simply deny the result, there is no need for teh itemstack

[brave sparrow]

It’s not a cancellable event

I sent the actual code for the event

[viral crag]

i did not say to cancel it

[brave sparrow]

It only uses the item result

It doesn’t check the abstract event result

[viral crag]

item result has usable enums of which DENY is one

[brave sparrow]

@viral crag

Spigot does not check that for this event, it sets the slot in the inventory

[lunar forge]

hi, I tried to use this,

        getConfig().getConfigurationSection("items").getKeys(false).forEach(key -> {
            String s = getConfig().getString("items." + key + ".dropped-from").replace("[", "").replace("]", "");
            System.out.println(s);
            itemStackHashMap.put(Material.matchMaterial(s), new ItemBuilder(
                    new ItemStack(getConfig().getInt("items." + key + ".id")))
                            .setAmount(getConfig().getInt("items." + key + ".amount"))
                            .setName(getConfig().getString("items." + key + ".title"))
                            .setLore(getConfig().getStringList("items." + key + ".lore"))
                            .setData(getConfig().getInt("items." + key + ".data"))
                    .toItemStack());
            chances.put(Material.valueOf(getConfig().getString("items." + key + ".dropped-from")), getConfig().getInt("items." + key + "chance"));
        });```

And that is giving this error:

[brave sparrow]

Seems like there’s no material WHEAT

You can see that where it says “No enum constant WHEAT”

[lunar forge]

[WHEAT]

Not WHEAT

When I try to replace it with " " instead of "" it says "No enum constant org.bukkit.Material. WHEAT "

And Material.WHEAT is a thing

[quiet ice]

Your issue might be regex, but idk

[brave sparrow]

Replace doesn’t use regex

[quiet ice]

It does afaik

ah no

[brave sparrow]

It doesn’t

[ivory sleet]

replaceAll uwu

[quiet ice]

replace all uses regex heh

[brave sparrow]

replaceAll and replaceFirst do

Yeah

[hasty prawn]

chances.put(Material.valueOf(getConfig().getString("items." + key + ".dropped-from")), getConfig().getInt("items." + key + "chance"));

Should be chances.put(Material.valueOf(s), getConfig().getInt("items." + key + "chance"));

You're only replacing the brackets when you're printing and not when you're using it.

[brave sparrow]

Yeah it’s that valueof

[hoary pawn]

hmm im trying to load a string from a presistentdatacontainer, but im getting this

[quiet ice]

You need to also pass the type

So something like .get(key, PersistentDataType.STRING), idk - all pseudocode

[lunar forge]

That worked, thanks

[twilit wharf]

How do I get the NMS Level object from a bukkit world? I try the whole getHandle() thing but that returns WorldServer

[hasty prawn]

That is the NMS object

Im guessing this is not from your plugin?

This is a SignGUI

[wooden fable]

eH

I tried that

But it still doesn't work

From this

[lost matrix]

You miss your config.yml in the compiled jar

[wooden fable]

    @EventHandler(priority = EventPriority.MONITOR)
    public void onPrepareAnvil(PrepareAnvilEvent e) {
        final ItemStack result = e.getResult();
        final ItemMeta meta = result.getItemMeta();

        if(!shouldCheck(e.getInventory())) return;
        if(!isMending(meta)) return;
        if(!isArmor(result)) return;
        e.getInventory().setItem(2, null);
        log("Called");
    }

[lost matrix]

Event registered?

[grand coral]

This is a older Version I want to do it in 1.16.5

[lost matrix]

debug every boolean statement

[wooden fable]

ofc

[grand coral]

Or do u know a way how to get sign input from a not existing sign

[wooden fable]

How is that going to help? We already know it gets called by the debug at the bottom

[lost matrix]

?notworking

[undone axle]

"Does not working" is a useless statement. Please describe what exactly is not working, what you expect it to do, and what actually happens. If you get any console errors, also ?paste the entire stacktrace.

[lost matrix]

this is from 2013... You should take a look at the protocol if you want to port this to newer verions

https://wiki.vg/Protocol

[wooden fable]

No errors, I don't know what else to say, the code is running and I've already tried PrepareAnvilEvent#setResult but that doesn't work either.

[lost matrix]

What version?

[wooden fable]

1.12.2

[lost matrix]

Why not use PrepareAnvilEvent#setResult(ItemStack) ?

[wooden fable]

Tried already, doesn't work.

[quiet ice]

In Java 8 how do I convert a codepoint (int) to a String?

eh, I'll just cast it.

[wooden fable]

        e.setResult(new ItemStack(Material.AIR));
        e.setResult(null);
        e.getInventory().setItem(2, null);
        e.getInventory().setItem(2, new ItemStack(Material.AIR));

I've tried all these but nothing works

[lost matrix]

Just tried it out. PrepareAnvilEvent#setResult(ItemStack) works fine on the latest version

[brave sparrow]

He’s trying to figure out why it’s not working for him

@wooden fable try removing every other plugin and just test with yours

You do need to make it setResult though @wooden fable

So do that first

setting the inventory slot wont work at all

[devout solstice]

Would anyone want to help with a twist I am going to make for a Minecraft manhunt dm me if you would like to help. I’m new to making plugins

[wooden fable]

I tested it with:

        e.setResult(new ItemStack(Material.AIR));
``` and ```java
        e.setResult(null);

but it still doesn't work.

[viral crag]

Event.Result.DENY instead of null

[brave sparrow]

Right but now we need to figure out why those two don’t work

[twilit wharf]

it says that it wants the type Level and not WorldServer

[brave sparrow]

Whereas setItem will never work

[brave sparrow]

For the last time, that does not work for this event

[viral crag]

null is not valid for InventoryEvent

[brave sparrow]

Yes it is

[viral crag]

for the return yes

[brave sparrow]

Dude

I looked at the code

It’s valid as null

Just accept that you’re wrong about this

[viral crag]

okay I am wrong - somewhere null must be mapped to default

[wooden fable]

I have now disabled all plugins and it still doesn't work for me.
Pom: https://pastebin.com/MGSvNTfS
The plugin has only one class: https://pastebin.com/ANXewhLP
Some logs: https://pastebin.com/Xwrh2ajM

[brave sparrow]

This may be a bug on the version of spigot you’re using then

I’ll take a deeper look later

One last thing, try setting null again as opposed to air @wooden fable

[delicate lynx]

try to delay set the item

[wooden fable]

Yes, I've tried that many times

Thank you very much for still helping.

[brave sparrow]

That will cause an exploit

[viral crag]

you were not responding to me, everything i read says Itemstack is NotNull so i am looking for alex's version

[wooden fable]

Maybe I have an idea, what if I use InventoryClickEvent and check if the item is armor with mending and if it is, I cancel the event.

You still see the result item but you can't pick it up anymore and then it's fine.

[grim ice]

ur still on tht

[grim ice]

Thats what I suggested earlier

[viral crag]

yeah looking for the alternate version to this: IMPORTANT: An ItemStack is only designed to contain items. Do not use this class to encapsulate Materials for which Material.isItem() returns false.

[wooden fable]

Yes, thanks again for the help

[grim ice]

https://github.com/2Hex/EntitySerializer

Anyone

has a code review

I wanna achieve more abstraction and a better design, any ideas

[ivory sleet]

Yes

Make interfaces for the api

It’s an interface right

[tight pagoda]

Cannot inherit from final 'net.md_5.bungee.api.chat.ComponentBuilder'

why does that not work

[ivory sleet]

Right now you’re just throwing concrete implementations at the consumer

[lost matrix]

Because that class is final. Why do you want to extend it anyways?

[tight pagoda]

because the class said it

da hell this suppose to mean?

[lost matrix]

Never call the constructor of your JavaPlugin class

[tight pagoda]

what

[hoary pawn]

ahh so it is plugin side, now i just need to remember what the constructor is lol

[lost matrix]

Im just looking at the javadocs. Where does it say that you should extend ComponentBuilder?

[tight pagoda]

https://hastebin.nl/UfnefZ4

[lost matrix]

new YourPlugin() <- illegal

[tight pagoda]

it was used in my plugin before

but now it doesnt work

[grim ice]

7smile can you took a look on this code? maybe tips of better design https://github.com/2Hex/EntitySerializer

if u dont have time its fine

[hoary pawn]

AHH FFS I THOUGHT I HAD REMOVED THAT

[tight pagoda]

how can i make it work then

[lunar forge]

How to fix this?

[brave sparrow]

you can't modify while iterating

[lunar forge]

What do you mean?

[solar dew]

Help-me here pls, what is the other agument of this method?

new PacketPlayOutSpawnEntity(entity,another argument);```

[lost matrix]

You can take that quite literally. You can not modify an ArrayList while iterating over it.
