[terse ore]

ty guys it worked

[sterile token]

In confuse you can use this for developing plugins? Or you need jdk?

I ask because im helping a friend to setup intellij idea

[wide coyote]

jdk is java development kit

[sterile token]

Oh im an idiot

[wide coyote]

and he already has that

[sterile token]

I was the name that confused me

Becuase i name as JDK-version

[sterile token]

Thanks!

[wide coyote]

np

[quaint mantle]

no

[sullen marlin]

define multithreading

[young knoll]

It uses multiple threads

[sullen marlin]

then yes

always has

[young knoll]

Chat is a thread, there’s the main thread, and several worldgen worker threads

Probably more

[short raptor]

How come people shit on it for being single threaded? Or is that not true anymore

[young knoll]

Probably because a lot of stuff is still on that main thread

[worldly ingot]

or people they're misinformed and believe everything they read on the internet as fact ;p

[young knoll]

Are you saying it’s not all fact

[terse ore]

How can I push a player backwards

[eternal night]

backwards relative to what

[terse ore]

to player

[eternal night]

Well, basically grab the vector from player B to A and scale it

if you want A to be knocked away from B

[ionic dagger]

could someone help me out here? im trying to manually set world spawn with a /spawnset command, but the coordinates dont save whenever i try to /goToSpawn

            plugin.getConfig().set("spawn.world", location.getWorld().getName());
            plugin.getConfig().set("spawn.x", location.getX());
            plugin.getConfig().set("spawn.y", location.getY());
            plugin.getConfig().set("spawn.z", location.getZ());
            plugin.getConfig().set("spawn.pitch", location.getPitch());
            plugin.getConfig().set("spawn.yaw", location.getYaw());

this is my config.yml vv

  ==: org.bukkit.Location
  world:
  x:
  y:
  z:
  pitch:
  yaw:

[young knoll]

You can just save the location directly

[sullen marlin]

set("spawn", location);

[young knoll]

Also did you call saveConfig

[ionic dagger]

yes coll

and i did that md

[sullen marlin]

well then you dont need this

[ionic dagger]

but im tryna figure it out the other way

i wanna set them all manually

would that be a lot more work than i think it is

lmao

[young knoll]

Not really

But why

[crimson verge]

why would you set them manually lmfao

[ionic dagger]

cause im tryna make a home command aswell

[crimson verge]

... not understanding why that would change things lol

[ionic dagger]

wait does it not

uh

2 minutes team

[fallow storm]

Is there a way to refresh the command tab list that the client sees? When I change a player's permissions it doesn't update that list until the player relogs or the /reload command is used (which obviously I won't use, but it proves that the list can be updated without relogging). Specifically this list
https://i.imgur.com/L3ymJuz.png

I've tried permissible.recalculatePermissions() but that doesn't update it

[young knoll]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/Player.html#updateCommands()

[fallow storm]

Thanks

[tranquil viper]

how should I go about speeding up spawn rates of a single spawner

I don’t want to change the spawn delay because it limits the amount of spawners that can be stacked at once

[terse ore]

How can I make a block object an itemstack?

[young knoll]

Increase the count

[tranquil viper]

wdym increase the count?

the count of what

mobs that spawn?

[ionic dagger]

ok

so

i thought setting them manually would let me define them in the config.yml

im new to all this so idk much about it lmao

could you help me figure out how to save the location to the config?

or anyone really

[young knoll]

Yes

[ionic dagger]

String homeName = args[0];
plugin.getConfig().set(homeName, location);

player.sendMessage(ChatColor.GREEN + "Home: " + ChatColor.YELLOW + homeName + ChatColor.GREEN + " has been set.");```

[tranquil viper]

How would I do that? Listen to the spawn event and then spawn x amount of entities?

[young knoll]

It’s a property of the spawner

But you can do that too

[tranquil viper]

oh fr?

How would I edit the property

[young knoll]

Does the javadocs have jt

[tranquil viper]

ion maybe

I'll check ig

thought I saw a thread though and it said you couldn't actually edit the property

[ionic dagger]

could i save a new location into the config by doing set("location", location);

[young knoll]

Yes

[young knoll]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/block/CreatureSpawner.html#setSpawnCount(int)

[tranquil viper]

oh cool

ty

[ionic dagger]

@young knoll why is this not adding anything to the config

[young knoll]

Did ya save it

[ionic dagger]

😄

im gonna kms

thanks

[sterile token]

Its possible to iterate over a Stream, replace some text and them return the replaced text string (in-line function)?

[young knoll]

Is it a stream of strings

[sterile token]

The stream is from a map

[paper viper]

you could do forEach

or smthing

and then map

wait

no

[young knoll]

Can’t you just do stream.map.collect

[paper viper]

im braindead rn

i have to go to sleep

but yeah thats what i thought, could you turn it into a data struct

and iterate over that

and then modify and replace as needed

[sterile token]

Would work with this Map<String, String>

and then a String replace(String text) { return}

Cuz its telling me that its a void

[sterile token]

Like this?

Map<String, String> palceholders = new HashMap<>();

String toString(String text) {
  return this.placeholders.entrySet().stream().map(text::replace);
}

[young knoll]

Probably not

Because the entryset stream won’t be a string

It’ll be Map.Entry<String, String>

[sterile token]

But i want to do it in-line

[young knoll]

On the key or the value

Or both

[sterile token]

Both because i wanna do text.replace(key, value) from placeholders and return an string (in-line)

[worldly ingot]

You're probably not going to get that in-line

[sterile token]

Take at look a this

public String toString(String input) {
        return this.placeholders.entrySet().stream().reduce(input, (text, entry) -> input.replace(entry.getKey(), entry.getValue()), (s1, s2) -> input);
}```

What do you think?

[worldly ingot]

Some things really just don't need to be streams lol

[sterile token]

If it really easy as everyone said why no one give an in line example?

Hum

[worldly ingot]

Why are you so hell-bent on making it single-lined?

Less lines != better

[sterile token]

But would work or not?

[worldly ingot]

Probably not because strings are immutable so I doubt that would work at all

but I've never used reduce so I don't know if that is a BiFunction or a BiConsumer

[drowsy helm]

just use a for loop man

[worldly ingot]

^

Skip the streams entirely

[drowsy helm]

streams are pretty inefficient aswell

[sterile token]

Not at least on Java 8

[lavish hemlock]

Yeah the idea behind streams is to make your life as a dev easier

If you spend more time worrying about how to use them

instead of using them

then you defeat the purpose of using them

[sterile token]

Yeah im trying to do a lambda loop that replace something using key,value from map and return the string

[young knoll]

I believe it was Sun Tzu who said “lmao streams are wack”

[sterile token]

Omg if you see my history, you will get tired of seeing stackoverflow links

I went through all stackoverflow and did not find a garbage

[worldly ingot]

I don't recall Sun Tzu saying that. Very wise of him. Very ahead of his time

[lavish hemlock]

That suggests you should try something else :)

[sterile token]

I cannot develop without using lamda

[kind hatch]

How do you think people did it before streams existed? .-.

I need that meme format. When were java streams added? (March 2014), People before March 2014, Idk wtf I'm doing.

[drowsy helm]

image circa March 2014

[young knoll]

I think I started java back then

It was literally unusable

I couldn’t even make a hello world program

[waxen plinth]

Using a map for this is already slow

This is about the slowest way you could possibly implement something like that

[sterile token]

So what i can do?

[waxen plinth]

How performance critical is it?

[sterile token]

I dont understand your questions

[waxen plinth]

How important is it that this code is fast

How often will it be run

[sterile token]

Its for a plugin

[waxen plinth]

...

That doesn't answer anything I asked

You're in #help-development of course it's for a plugin

[sterile token]

Im trying to make a String replacer based on map key-value, for text message

[waxen plinth]

I understand that

[young knoll]

So like papi

[waxen plinth]

You still did not answer either of my questions

[sterile token]

I dont udnerstand your questions it too OP

[waxen plinth]

OP?

I am just asking how often the code will be run

I feel like that's not a hard question to answer

[sterile token]

I dont know

Cuz it for a library i will publish free on gth

[waxen plinth]

Then assume it is very performance critical

Do the placeholders have a pattern, like are they surrounded in %% or {} or something?

Or are they just plain strings in any format?

[sterile token]

Using the {}

[waxen plinth]

Then you should use a regex for matching

[sterile token]

I have literally this:

public Map<String, String> placeholders = new HashMap<>();

public String toString(String text) {
// I cannot figure how to return the replaced all in-line
}

[waxen plinth]

Yeah the simplest way to make it fast is to use a regex to match the placeholders

That way you're not just blindly calling replace for every possible placeholder

Imagine if there are hundreds, or thousands, of placeholders registered

It would be iterating over thousands of placeholders and trying to string replace every one of them, that could be extremely slow

So you can find the placeholders in the string, then get them in the map and only replace the ones that are actually in the string

You can take it a step further using a StringBuilder if you want to

[sterile token]

I tried with forEach() but its a void

[waxen plinth]

You want the simplest way to do it?

Fine

[young knoll]

So that’s how papi does it

Why didn’t I think of that

[waxen plinth]

There is a better way still

for (Entry<String, String> placeholder : placeholders.entrySet()) {
  text = text.replace(placeholder.getKey(), placeholder.getValue());
}
return text;```

[ebon arrow]

Is there a way, either with maven or with java, to automatically increase the version number every time you export the project?

[waxen plinth]

This is the most obvious way to implement it but it is going to be very slow

[young knoll]

I’m somewhat curious

[lavish hemlock]

I'd personally implement the placeholder parsing myself.

[buoyant viper]

java 8 streams were literally infamously slow werent they

[lavish hemlock]

It's not too hard.

[waxen plinth]

I would as well

The optimal way to do it is with a prefix tree

[sterile token]

Oh my eyes herts

I do this: String stoString(String text) { return this.placeholders.forEach((key, value) -> text.replace(key, value)); } But its a void so i cannot return it

[sterile token]

Im trying to do it as this in-line code

[young knoll]

A new thing to research, exciting

[waxen plinth]

https://github.com/Redempt/Crunch/blob/master/src/redempt/crunch/data/CharTree.java

[sterile token]

How?

[ebon arrow]

@young knoll can i pm you quick?

[waxen plinth]

Very sus

"TheGamingJew" wants to pm you

[young knoll]

Sure why not

[ebon arrow]

I mean, I could ask to pm you too if you want, but I dont know you that well...

[young knoll]

I always wondered how papi maintained performance with 1k placeholders

[waxen plinth]

I don't know if papi uses a prefix tree

But I'm pretty sure it is the optimal solution for a multi replace

[young knoll]

My brain didn’t even think of the regex method

[sterile token]

Hmn

I would take a look

[waxen plinth]

I literally gave you a solution

[sterile token]

I dont support not using lambda

[waxen plinth]

A bad one, but still better than what you're trying to do

[waxen plinth]

Ok then have fun making a terrible solution

[sterile token]

Oh lol?

[waxen plinth]

Because this is not a good use case for lambdas and streams

[young knoll]

Everything must be a lambda

[waxen plinth]

The solution I gave you is already really slow

And your way of implementing it will be even slower

[lavish hemlock]

Lambdas can also increase code complexity and class file size! :)

They are a great tool in moderation, however.

[young knoll]

Arrays.asList(“Hello World”).forEach(System.out::println)

[waxen plinth]

I personally really love lambdas but there are cases where you don't use them

[waxen plinth]

Stream.of(1).forEach(System::exit);

[hasty prawn]

Lambdas are great

[lavish hemlock]

Lambda everything

[young knoll]

Exactly

[sterile token]

Yeah idk why no one agree with me so

[lavish hemlock]

Actually I think we just discovered Lisp

[young knoll]

EssentialsXLambda fork coming soon

[hasty prawn]

They're just saying your use case for lambda's isn't right

[lavish hemlock]

No we like lambdas you're just using them poorly

[young knoll]

I like lambs

[hasty prawn]

thats nice coll

[sterile token]

Oh i will definitly get around making an own api so

[waxen plinth]

With the level of competence you've shown I'll steer clear of it

[young knoll]

Imma switch to it

Heck redlib, it doesn’t have enough streams

[sterile token]

Im not native speaker

[lavish hemlock]

lmao

[young knoll]

That too

[lavish hemlock]

Not English competence, code competence.

[hasty prawn]

RedLib?
VeranoLib?

[waxen plinth]

heresy

[lavish hemlock]

MaowLib is actually good though

[young knoll]

Fuckin redlib isn’t even red

[waxen plinth]

What's it got

[lavish hemlock]

See, I code stuff that's on par with the stdlib

[lavish hemlock]

Nothing cuz I can't think of any ideas

[waxen plinth]

lol

[sterile token]

https://github.com/Redempt?

[waxen plinth]

huh

[young knoll]

An item builder!

Very original idea

[waxen plinth]

yes that's my github

[sterile token]

Allright i will check your stream implementation

[waxen plinth]

What stream implementation

[lavish hemlock]

https://github.com/MaowImpl

[sterile token]

I dont wanna be 30 years and dont have no more brains cuz of java

[young knoll]

We reimplementing streams now?

[lavish hemlock]

I can do that 🖐️

[waxen plinth]

I'm too lazy

[hasty prawn]

Nice mistakes repo I learned alot

[lavish hemlock]

shush

[waxen plinth]

Rust fan behold

https://github.com/Redempt/constant_pool

[young knoll]

Don’t let your fan get rusty

[hasty prawn]

Hey Redempt

[minor otter]

Probably a no brainer but I want to ask anyway, is a world populater the best way to generate ores

[waxen plinth]

hi

[hasty prawn]

Has anyone ever told you that you're a nerd

Very smart, still a nerd

[waxen plinth]

if I had a nickel for every time I had been called a nerd I would probably have well over $10

[young knoll]

Nerd

[hasty prawn]

I'm glad I just made you $0.05

[waxen plinth]

umm actually it was hypothetical

you calling me a nerd does not net me any additional income

[young knoll]

Not anymore

Check under your pillow in the morning

[waxen plinth]

😱

the nerd fairy??

[young knoll]

Exactly

[lavish hemlock]

I am inside your home.

[hasty prawn]

You'll have exactly 1 dime in the morning

[kind hatch]

Just write a bot to spam it over and over again. Infinite money glitch

[waxen plinth]

as usual

(we are gay)

[lavish hemlock]

I am raiding your pantry for caffeine and Doritos.

[waxen plinth]

you will find it barren

[lavish hemlock]

Terrible.

I am displeased by your lack of offering.

[waxen plinth]

I have other offerings

Have you any interest in a lecture about parsers?

[young knoll]

Redempt and maow lovers confirmed?

[waxen plinth]

😳

[young knoll]

(Not clickbait)

[lavish hemlock]

Oh sure

[tall nova]

kkk

[lavish hemlock]

Nah sorry I already have someone

[young knoll]

Exactly

It’s redempt

[lavish hemlock]

No

My Redempt-ion arc hasn't come yet.

[young knoll]

🥁

[lavish hemlock]

I-

I was just about to do that

[young knoll]

You may be inside my house

[sterile token]

So there is no lambda expression for executing a void and returning a string?

[young knoll]

But I’m inside your brain

[lavish hemlock]

Oh dear

The table turns have turned

[kind hatch]

Walk through that logic. You are running a void method. Therefore it won't ever return anything. You could set an object that exists outside the method, but just use a method that returns a string in the first place.

[sterile token]

Allright thanks

I will keep it

[ebon arrow]

@waxen plinth Now its your turn haha, do you use maven?

[waxen plinth]

gradle

[ebon arrow]

oof

ugg

lol

[twilit nexus]

Would anyone be able to tell me what I am doing wrong here?

if (p.getUniqueId().toString() == "8d129761-4315-4c33-904d-19df65eb1d43") {
            event.joinMessage(Component.text("Test"));
        }

[waxen plinth]

== on a string

Gotta do .equals

[twilit nexus]

Ohhhhhh

That makes sense now XD

[kind hatch]

You could also do a UUID comparison.

if (p.getUniqueId().equals(UUID.fromString("8d129761-4315-4c33-904d-19df65eb1d43"))) {
  event.joinMessage(Component.text("Test"));
}

[twilit nexus]

I gotchu

I'm still new to messing around with UUIDs

[eternal night]

that will also not work

== compares instances

which clearly, these two are two different instances

[twilit nexus]

I found that this works which is what redempt suggested

if (Objects.equals(p.getUniqueId().toString(), "8d129761-4315-4c33-904d-19df65eb1d43")) {
            event.joinMessage(Component.text("Test"));
        }

[wet breach]

== is for object comparison

[eternal night]

Yes

instance comparison

identity comparison

[kind hatch]

How so? It would be comparing UUID objects, not strings.

[eternal night]

okay ?

that is the entire point

comparing objects using == will not compare their contents

and then return true

it returns if the identify of the two objects are the same, e.g. they are the same instance (in the case of objects)

the reason you can use == on primitives is because they don't have the concept of identity beyond value

[wet breach]

UUID.compareTo() wold probably work

[eternal night]

just .equals

compareTo computes ascending/descending order

[kind hatch]

My bad. You're right.

[neon minnow]

Hi guys I’m just wondering is the Minecraft old hurt sound still exist in the client / server or not anymore ? (The old before mc 1.2) when you fall and things like that — can the server send that packet sound or does it need a resource pack: thank you.

[ancient jackal]

adding enchantment to an item with addUnsafeEnchantment(ench, n) does not work using this little bit of code I whipped up in 20 minutes java for(Enchantment enchantment : Enchantment.values()) { item.addUnsafeEnchantment(enchantment, 255); event.getEnchanter().sendMessage(enchantment + " " + itemMeta.getEnchantLevel(enchantment) + " added to " + item.getType().name()); }

it does say the enchantment is added but with level 0

I did add the enchant to the itemMeta before but it would only add a max level of 255, this doesn't even add that

I tried to add the level 32767 of every ench

nevermind I was setting the item meta still like an idiot after the for loop

still adds enchantment level 255 though, nothing more

[sharp flare]

what

[ancient jackal]

        for(Enchantment enchantment : Enchantment.values()) {
            int level = 32767;
            item.addUnsafeEnchantment(enchantment, level);
            event.getEnchanter().sendMessage(enchantment + " " + item.getItemMeta().getEnchantLevel(enchantment) + " added to " + item.getType().name());
        }```
This says the item has an enchantment level of 32767 but hovering over the item says 255

[sharp flare]

its because minecraft changed it

its now limited to 255 by default

[ancient jackal]

well minecraft is dumb for that then

what is it, a short short?

[sharp flare]

you check the amount of level inside the item by dumping it ig

[sullen dome]

Wasn’t the enchantment cap at 10?

[sharp flare]

for unsafe enchantment its not

[sullen dome]

Ah I see

[sharp flare]

but if you're talking about vanilla enchants, the max supported is 10 ig

in terms of mechanics

[sullen dome]

Yea didn’t know spigot has an own cap

[sullen marlin]

it doesnt

the value is a byte

which means max of 255

[sharp flare]

idk why they (mc) changed it to byte

but it make sense ig when anarchy servers try to use unsafe enchantments in their lores

[drifting vault]

i somewhat managed to do what i wanted using NBTAPI. i still need to learn how to modify NBTContainers so that the entity doesnt respawn at the spot he was snatched

same goes for the unique id being the same, using the get command with a restored mob outputs no entity found message

[midnight shore]

You’ll need a resource pack i guess

[short raptor]

Does anyone know if it's the same with the normal online Player ? (when using Player.setStatistic())

[tardy delta]

No

[blazing scarab]

What do you want to do?

[ancient jackal]

if enchantments are saved as bytes why does adding an unsafe enchantment with any level above 255 still have that level you added in the meta? does the enchantment still behave as powerful as a level 32767?

[quaint mantle]

Resource pack

[sharp flare]

I don't think those numbers behave like they supposed to be since vanilla mechanics has its own enchantment limit unless u do ur own custom enchants with its own functions

[sullen marlin]

I never understand the obsession with stupid enchantments

sharpness 500 countered with protection 500 may as well be sharpness 1 countered with protection 1

but big numbers shiny I guess

[sullen marlin]

Impossible in 1.18 at least. MC wiki disagrees with you too https://minecraft.fandom.com/wiki/Enchanting

'When enchanted with the /give command, the maximum enchantment level is 255‌[Java Edition only].'

[drifting vault]

Store entity data in a file and load it in another world, basically a way to transfer your pets between worlds without the hassle of admin commands such as world edit

[ancient jackal]

what I mean is if you use ItemStack's addUnsafeEnchantment method, the item's meta stores the enchantment as a short

[sullen marlin]

from the wiki

' lvl: The level of the enchantment, where 1 is level 1. Values are clamped between 0 and 255 when reading.'

        return MathHelper.clamp(nbttagcompound.getInt("lvl"), (int) 0, (int) 255);
    }```

client will have the same code, it can't be overriden

[ancient jackal]

I see, wonder why that change was made

[sullen marlin]

because stupid enchants are stupid

sharpness 500 countered with protection 500 may as well be sharpness 1 countered with protection 1

[ancient jackal]

stupid enchants are stupidly fun as well

[sullen marlin]

and there's no meaningful difference between say sharpness 500 and sharpness 5000

both are instant kill

[ancient jackal]

you know what they say, the bigger the better

[sullen marlin]

looks like limit was added in 1.15

[ancient jackal]

huh, so even when it said 32k in the tool tip it was really only behaving like 255 for a while then

oh well, you're right about 255 being enough anyways

[sinful kelp]

anyone got a GUI Library/Resource with Action mapping to Items. About to create my own unless someone has one.

[tardy delta]

https://github.com/FourteenBrush/MagmaBuildNetwork/tree/main/src/main/java/io/github/FourteenBrush/MagmaBuildNetwork/gui

That's how i did it

[quaint mantle]

im not very good with inventories, is there any event for changing an item in inventories ?

dragging them in the inventory to seperate their stacks & etc ...

i want players to be able to only move items in an openned gui

and not place the items in their own inventory

i want it to be only moveable in this open gui and not player's inventory

this is what i tried and failed

[minor otter]

May be a lil much to ask but does anyone have a working example of a block populator on 1.18?

[sharp flare]

inventoryclick event, you gotta do checks for it

just cancel them if their trying to move items against the GUI, from checking the view and holder

[quaint mantle]

thanks, it worked

i also fixed something with drag

[sharp flare]

great

[dull whale]

how do I make a falling block's texture another block?

[hybrid spoke]

Unable to find handler list for event org.bukkit.event.player.PlayerEvent. Static getHandlerList method required!

[hybrid spoke]

this will not work

[daring lark]

what should i do?

[hybrid spoke]

use the right event

[daring lark]

Do you know which event?

[hybrid spoke]

whats your goal?

[sharp flare]

are u making ur own event?

[daring lark]

to check if player has speed boots and if true then give him speed 2

[daring lark]

no

[hybrid spoke]

no he's using PlayerEvent

[sharp flare]

Aight

[hybrid spoke]

so then depends on when you want to check that, you either need the InventoryClickEvent, a timer, PlayerMoveEvent or anything in that direction

[daring lark]

i'll try

[sharp flare]

PlayerMoveEvent, it gets triggered many times, optimize ur code for it

[clever solar]

Hello, I have a small question, I am developing a logging plugin for my server, so I use apache poi which allows you to create excel files to make the reading easier to understand.

The problem is that when I build my plugins it can't use the apache poi classes, I have tried different ways but without result, does anyone have a solution for me?

[drowsy helm]

have you shaded it?

[hardy swan]

is there a way to specify a primary key that consists of all the columns without writing all the columns

when writing a create table statement?

[drowsy helm]

are you talking about sql?

[hardy swan]

yes

[drowsy helm]

could you elaborate on what you mean by "consists of all the columns" not sure what you mean by that

[vocal obsidian]

A Panel Making Plugin with subcategories I need a GUI for custom recipes
someone know that Plugin

?

[hardy swan]

create table A (
  a integer,
  b integer,
  c integer,
  primary key (a, b, c)
);

[drowsy helm]

oh a composite primary key

[clever solar]

In my build.gradle I put in implementation.

[hardy swan]

is there a keyword or sorts to signify that the primary key consists of all columns

[drowsy helm]

no, not that im aware of

[clever solar]

implementation group: 'org.apache.poi', name:'poi', version: '5.2.0'

[drowsy helm]

i've got no clue about gradle sorry

[raw ibex]

How would I make a custom villager GUI? Is that possible with spigot?

Such as hypixel bedwars shop

[drowsy helm]

theres a few apis out there for that

[raw ibex]

OK

What would I search for/

[drowsy helm]

check out villagergui api

if you want to do it without an api check out https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/inventory/MerchantRecipe.html
and
https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/inventory/Merchant.html
but that requires spoofing of a villager and can get messy

[raw ibex]

OK

[raw ibex]

What's spooof

[drowsy helm]

like you have to hide the villager with trickery or use workarounds

[raw ibex]

OH

what do you mean hide?

[drowsy helm]

just hide the villager from the player

if you just want a pure gui

[raw ibex]

its not just a gui

its bedwars shop

[chrome beacon]

Just open a normal chest GUI then

[raw ibex]

ok

i basicaly want custom villager trade

like bedwars shop

[cold field]

Guys quick question. Is there an event like PlayerDropItem but that returns the item dropped location?

If I get the item and then I use getLocation it returns the player location -.-

Hum, I see. Does it exists an event for that or do I need to wait some ticks before checking location?

[quaint mantle]

I guess you could do a bukkit runnable the runs every set amount of ticks and checks if the item is grounded, and if it never gets grounded or doesn’t exist just cancel the runnable

[cold field]

I'm doing a runnable that runs after 5 ticks the player has dropped the item. If it meets certain conditions the item is teleported back to the player

[quaint mantle]

alr cool

[analog hinge]

Hi just came to the server :)
I needed an answer that I couldn't find on google
I noticed in the Material enum that there was quite a few materials with the LEGACY prefix.
My question was why when iterating over the materials is it NOT selecting them when using the enum method .contains(String str) ?
Here a bit more context, I had a ArrayList<Material> sourceMaterials list that I was using to select materials with LOG in them using a for loop and if statements.

for (Material material : Material.values())
{
  String matName = material.name(); // convenience variable

  if (matName.contains("LOG"))                                        // FILTER: log types
    sourceMaterials.add(material);
  else if (matName.contains("STEM"))
    if (matName.contains("WARPED") || matName.contains("CRIMSON"))    // FILTER: stem types
      sourceMaterials.add(material);
}

I got concerned when I saw all those LEGACY materials that I'd have the rework my selection code but it turns out the for loop doesn't even detect the LEGACY materials and on my IDE they appear as dashed over?? here's a screenshot: https://prnt.sc/26q3l8f
Can someone explain this to me?
I only started java about 4 days ago and spigot yesterday so I'm a bit confused there

[worldly ingot]

It's a weird hacky workaround with a library called ASM. So long as your plugin declares api-version in the plugin.yml, those constants don't even exist at runtime for your plugin

You can disregard them, really

It's so that plugins from pre-1.13 can work with the new 1.13 Material names (because a large chunk of them were renamed), but Bukkit tries its best to keep forwards compatibility

[analog hinge]

alright thanks for the clear answer
if I understand correctly those LEGACY values basically aren't even in the enum when the plugin runs at startup?

[worldly ingot]

Pretty much, yeah. A plugin compiled against 1.12... for example referring to Material.WATCH, would then be ASM'd to refer to LEGACY_WATCH on a 1.13 server and mapped to CLOCK

[analog hinge]

for 1.18

[worldly ingot]

Though for 1.13+ callers, they're not included in things like values(), valueOf(), or matchMaterial()

Don't refer to these constants at all in source either. Really, just pretend they don't exist ;p

[analog hinge]

ASM?

[worldly ingot]

It's a library that allows bytecode manipulation at runtime

[analog hinge]

oh is that similar as bit manipulation stuff for c++

because I still haven't really touched that subject yet

I still have a lot to learn

[worldly ingot]

Probably not quite the same. Java is compiled down to bytecode which is understood by the JVM. It's how things run

[drowsy helm]

bytecode manipulation is very complex and in most cases you won't ever use it

[worldly ingot]

^

[analog hinge]

alright

[worldly ingot]

In my 8 years, I've never used it

[analog hinge]

anyway thanks for the help, nice to see the community is active

[worldly ingot]

[dark arrow]

thx

[dull whale]

I want to move a group of blocks simultaneously as if they have velocity
I imagine having an entity for each would cause lag is it posibble to do this with resource packs or soemthing

[tender shard]

uninstall the minecraft plugin

then everything will work fine

[tender shard]

no. how many blocks?

uninstall the minecraft plugin

then it'll work

[earnest wigeon]

How i generate 50 chunk around player

[dull whale]

say 100

[tender shard]

set the server's view distance to 7 and it will automatically generate 50 chunks

[earnest wigeon]

ahh thank

[tender shard]

this stupid plugin is totally broken. whenever you have intellij problems, just uninstall it and now everything will work automagically lol

[tender shard]

hm that's not really very much. if the server can't handle 100 entities, RIP

I don't see any other way then to summon falling blocks or similar things

[dull whale]

makes sense

thanks

[halcyon sage]

Hi, how can I get the player entity using a varable?

[tender shard]

what?

which player?

[halcyon sage]

I am making a tpbow plugin

@EventHandler
    public void onBowShoot(EntityShootBowEvent event) {
    

    }

[tender shard]

use event.getEntity()

[dull whale]

check if the entity is player then cast it to player

[tender shard]

then check if that entity is instanceof Player

and then cast it

[halcyon sage]

ok thanks

tyyyy

How can I make the player teleport to the point where the arrow falls?

[tender shard]

there's something like ProjectileHitEvent or similar

then just get the arrow's location and TP the player there

[halcyon sage]

okay thanks

but how can I have the player entity and have access to player.sendMessage?

[tender shard]

you have to store it somewhere

for example:

oh wait, doesn't Arrow have a method like getShooter?

[halcyon sage]

ProjectileHitEvent

[tender shard]

you realize that getEntity returns the arrow?

[halcyon sage]

it works

[tender shard]

Projectile.getShooter() returns a projectilesource. Check if that is instanceof Player, then cast it. Now you have the shooting player

[tender shard]

that does NOT work

it will throw a ClassCastException because you are trying to cast a Projectile to a player

[tender shard]

^

[halcyon sage]

i didnt understand xd

I've done this for now:

    public void onBowShoot(EntityShootBowEvent event) {

        if(event.getEntity() instanceof Player) {
            Player player = (Player) event.getEntity();
            
        }

    }

but I got stuck for a while because I don't know how to continue ahaha

?

ok

done

[tardy delta]

yes

[halcyon sage]

what I wanted to do was: "when the player shoots the arrow, teleport him to the point where it falls".

[tardy delta]

the entity is the shooter

[halcyon sage]

how can i do that

[tender shard]

in EntityShoowBotEvent yes, in ProjectileHitEvent, no

[glossy venture]

isnt there a projectile hit event

[tender shard]

yes. something like this. but of course don't blindly cast to player in the first line - check if it's actually a player beforehand

[glossy venture]

yeah you had BowShootEvent first bro

[halcyon sage]

Location location = event.getEntity().getLocation(); dont work

[tender shard]

?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.

[halcyon sage]

cannot resolve simbol "location"

[glossy venture]

import it?

[halcyon sage]

LOL

sorry hahaha

[glossy venture]

and make sure its uppercase Location

[halcyon sage]

yes it is

[glossy venture]

ah ok then it should work now right

[halcyon sage]

.getShooter(); no

EntityShootBowEvent

right

[tender shard]

do yuo people remember my awesome ?notworking command?

?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.

but that's actually what most people write, see here lol

"no working" is also common

yes

[pine island]

what is the event name for projectiles being fired also how do i know what kind of projectile it is?

making custom projectile trails

so i would need to summon ittems and clear them need help with that too\

[errant narwhal]

hmm i want to make a new itemstack is dust by bukkit coding but i want to when i place and break it it will drop an item stack how to do this

[pine island]

check for the block to be broken and placed in x amount of time then summon a item stack

or give it to the player

[quaint mantle]

?pdc

[undone axle]

https://www.spigotmc.org/threads/a-guide-to-1-14-persistentdataholder-api.371200/

[errant narwhal]

but when doing this every block same id when break it will drop that

i only want for this block ;-;

[tender shard]

EntityShoowBowEvent i guess

to know what kind of projectile it is: instanceof Arrow, instanceof Trident, etc

[tender shard]

you need my library CustomBlockData

[pine island]

what if i want eggs

[tender shard]

https://www.spigotmc.org/threads/custom-block-data-persistentdatacontainer-for-blocks.512422/

[pine island]

entity shoot event?

[tender shard]

go to the fridge

[pine island]

lmao

[tender shard]

ProjectileLaunchEvent or sth

[errant narwhal]

thankyousomuch

[pine island]

alr tysm

[tender shard]

np & np 🙂

[pine island]

is ther a way to make a class for event handlers

[errant narwhal]

do you know how to use maven?

[pine island]

just to make the code clean

[tender shard]

yes

[grim ice]

Asynchronous tasks should never access any API in Bukkit. Great care should be taken to assure the thread-safety of asynchronous tasks.

is there a workaround for this

[tender shard]

true

[grim ice]

not really good with multithreading

[tender shard]

yes. doing stuff synced

[pine island]

like the way u can create commands in a diff class can u do the same with events?

[grim ice]

i dont wanna lag main thread

[tender shard]

sure, why not?

[pine island]

hmm

[tender shard]

what are you trying to do?

[errant narwhal]

and at this
PersistentDataContainer customBlockData = new CustomBlockData(block, plugin);
is the block is itemstack?

[pine island]

im lazy ill do it in my next prject my main class is so ugly

[grim ice]

im looping through every player, and doing other stuff every 20 ticks

[tender shard]

no, no. the block is the block you have placed, to store information about what it should drop when being broken

[grim ice]

im looking to do this without affecting performance

[tender shard]

how would that create lag?!

[grim ice]

idk

i wanna make it optimized tho

[tender shard]

you can loop over all players hundred times per tick without any problem

[grim ice]

o

[tender shard]

the server itself loops over EVERY ENTITY EVERY TICK

[grim ice]

ok fine then

[tender shard]

and it also does way more other things every tick

[pine island]

alr

tysm

[errant narwhal]

do you have a guide for install maven? i search on google but i don't understand ;-;

[tender shard]

one sec

[tender shard]

https://blog.jeff-media.com/how-to-create-your-first-minecraft-plugin-using-the-spigot-api-and-maven/

[rough drift]

so um, i need to check if a text is a command (any command), since I have a configuration section for commands to execute and if a command that is inserted isn't a valid command it sends Unknown command. Type "/help" for help. in console, and I'd like to avoid that

[tender shard]

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

then cancel it if it's one of your commands

[rough drift]

wdym

[tender shard]

and do your stuff

[errant narwhal]

add commands: in plugin.yml

[tender shard]

what didnt you understand?

[rough drift]

I don't need to check my commands

i need to check if its a non valid command

such as passing "hello world" as a command in the configuration

[errant narwhal]

is there anyway for add maven for esclipes?

[rough drift]

commands:
  - say hi # valid
  - hello world # invalid
```how can i check if a command is invalid

[errant narwhal]

f

nah

[rough drift]

yes

[errant narwhal]

u don't understand

[rough drift]

there was a plugin for it

[rough drift]

what don't i understand exactly

[errant narwhal]

@rough drift u don't have args sub command

[quaint mantle]

Yes?

[errant narwhal]

then

[pine island]

this works right?

[errant narwhal]

only add one lettle not 2

[rough drift]

oh god... that is in the config.yml, its command to be specified to run at certain times

[errant narwhal]

like edit say hi to sayhi

[errant narwhal]

oh

can u show ur plugin.yml?

[rough drift]

why... would i need?

My commands work, i need to check if commands inputted by the user are valid commands the console could do

such as /say or /gamemode

those are valid

[hollow bluff]

yup

[rough drift]

but /thisisanonexistingcommand aint

[errant narwhal]

oh i think u need a someone better than me 😄

[rough drift]

well thanks for trying to help :D

[errant narwhal]

can you give me a guide please

[rough drift]

also yes, you can use maven on eclipse

there was a plugin for it

lemme find it for ya

[errant narwhal]

because i am not good at config file XD

pretty sure there are ones that exist if u google it

Someone know how to do this ? I want do a plugin statut !

I can't pu image

https://cdn.discordapp.com/attachments/600331193325584385/940255337137721434/unknown.png

[spiral light]

you need to confirm your profile to post images

[sharp flare]

just make one, not that difficult if u try

[spiral light]

a plugin to provide a webpage with those stats ?

[red sedge]

List<String> emojiList = Config.getStringList("emojis");
        for (String i : emojiList) {
            List<String> list = List.of(i.split("\\|"));
            String replacement = list.get(0);
            String syntax = list.get(1);
            String noColorSyntax = "!" + syntax;
            String permission = list.get(2);
            if (requirePermission &&
                    (!p.hasPermission("server.chat.emoji." + permission) && !p.hasPermission("server.chat.emoji.*"))) {
                continue;
            }
            str = str
                    .replaceAll(noColorSyntax, ChatColor.stripColor(Misc.colouredNoEmoji(replacement + "&f")))
                    .replaceAll(syntax, Misc.colouredNoEmoji(replacement));
        }
        return str;
``` how can i make this more efficient

[fallen thunder]

yeah or what's the name of this ?

[full elbow]

i don`t know how to cod

[spiral light]

welll... idk who the hell knows every page and every plugin in the world O.o

[sharp flare]

not a reason to try

[spiral light]

for disabling elytra and you dont know how to code java you can take a look at the skript thing that exist

[sharp flare]

skript is not recommended on live servers

[fallen thunder]

no just the name of this systeme it's an uptime checker or downtimer checker ?

[spiral light]

uptime .... ?

like the image tells you

[red sedge]

no its not recommended if you are using it for something except small things

like idk a playtime command or /gmc commands

[sharp flare]

I guess if he knows what he's doing, worth a try

[golden kelp]

hello guys, I want to create a custom potion which makes the player double jump, how can I do so?

[quaint mantle]

place a block when player tried to jump in the air while he has the potion effect (could be either through pdc with some effects)

[golden kelp]

I have an alt idea, whenever the player tries to double jump the PlayerToggleFlightEvent (iirc thats what it is called) is called and then I can track if the player has the effect and if he does I can give him a lil boost
so I need to learn how to

1. Check if the player has my custom effect
2. Give the player a lil boost

[sage dragon]

Might be a stupid question, but how would I actually check if a player has an inventory currently open?
Player#getOpenInventory never returns null, so does InventoryView#getTopInventory and InventoryView#getBottomInventory never returns null either...

[brave sparrow]

The boost is just velocity. PlayerToggleFlightEvent is only going to be called if the player has setAllowFlight set to true, which does carry with it some important side effects, like no fall damage

[golden kelp]

frick

what can I do then?

[brave sparrow]

That’s the best way to do a double jump

Lol

[golden kelp]

have u ever implemented double jump?

is triple jump implementable?

[dark arrow]

is there is any good libraries to make custom enchants easier

[golden kelp]

    private void groundUpdate (Player player) {
        Location location = player.getPlayer ().getLocation ();

Bro

[golden kelp]

yea?

[restive tangle]

Have you done your daily prayers yet?

[golden kelp]

Why?

[restive tangle]

It's the daily prayers, it should be done daily obviously

[golden kelp]

bruh

[restive tangle]

Yes

[golden kelp]

[tender shard]

I was pinged here

but I cant find it

lol

so I guess I'm fine

[analog hinge]

Trying to make an EnumMap with Material as key and ArrayList<String> as value
tried this but it's telling me it can't resolve the constructor and I can't see why

EnumMap<Material, ArrayList<String>> recipesMap = new EnumMap<Material, ArrayList<String>>();

any idea?

[eternal night]

you need to pass the enum key class to the constructor afaik

[analog hinge]

well i did

Material is the enum

[eternal night]

you didn't

final Map<Material, List<String>> map = new EnumMap<>(Material.class);

[analog hinge]

oh yeah mean that, yeah I was confused

alright ill try

[tall nova]

https://hatebin.com/psbwrfqctq
I run this class everytime a player dies using the PlayerDeathEvent, when it gets triggered the server lags a lot and I immediately or eventually get a ticking world exception and the server crashes (I’m using Mojang mappings)

[eternal night]

I mean, the other is just generic argument specification

not really passing anything

[analog hinge]

it works thanks :)

started java less than a week ago so im a bit lost sometimes x)

[eternal night]

Ohhh

yea no worries then 😅

thought you had some experience as you are using an enum map

[analog hinge]

yeah I know C++, did a bit a C, python and some other

I'm still not used to EVERYTHING being classes lol

it's also super fun because it's the first time I actually make a development project
These past few years it's only been learning, learning and learning...

without even applying what I had learnt to a real project

[golden kelp]

Hello guys I want to make a custom potion, how can I do so, I want to make a potion which gives u ability to double jump (I have the double jump worked out) but dunno how to do the tracking if playuer has the potion effect

[young knoll]

Add them to a map

With a time stamp of when it runs out

[waxen plinth]

You would need to keep track of it yourself, you can't add your own potion effects

[golden kelp]

oo

[waxen plinth]

You can do that with a map like coll said

[golden kelp]

Thanks

[waxen plinth]

You could also use a scoreboard tag or pdc

Both of those would be persistent, not sure if you need that

[golden kelp]

Nah i can use a HashMap for it, dont need any permanent storage

[stuck oasis]

Hey I was trying to build a Minecraft plugin and used the Minecraft Coding Plugin template for Spigot and I don't know how to implement the main class in "src/main/me.cit.PluginLoader". In Manifest.mf it says "Invalid main class"

[grim ice]

is there a way to get players nearby a player in a specific area

[vocal cloud]

?jd

[undone axle]

Spigot: https://hub.spigotmc.org/javadocs/spigot
BungeeCord: https://ci.md-5.net/job/BungeeCord/ws/api/target/apidocs/index.html
BungeeCord Chat: https://javadoc.io/doc/net.md-5/bungeecord-chat/latest/index.html

[grim ice]

I want to get players in the 3x3 area where the player is in the center

[vocal cloud]

this? https://hub.spigotmc.org/javadocs/spigot/org/bukkit/entity/Entity.html#getNearbyEntities(double,double,double)

[grim ice]

so

[young knoll]

There’s one that even accepts a filter iirc

[grim ice]

how am I supposed to use it in my case? not sure

[young knoll]

Player#getNearbyEntities(1.5,1.5,1.5)?

[grim ice]

4.5, 4.5, 4.5?

[young knoll]

You want a 3x3 area

Where would 4.5 come from

[grim ice]

alr im drunk

ty

[young knoll]

The numbers are radius iirc

[rough drift]

?

[lost matrix]

You dont need a Manifest file for spigot plugins. Could you send a link to this "Minecraft Coding Plugin template"?

[rough drift]

What plugin template are you using?!

[lost matrix]

There is a command map that contains all commands. It however is not exposed. This means
you either need CraftBukkit or reflections to access it.

[blazing scarab]

(Paper)

[stuck oasis]

It's the Minecraft Dev Plugin for intellij and chose spigot there

[lost matrix]

I see. Have you worked with a dependency manager before?

[stuck oasis]

Nope

First time building a plugin

[lost matrix]

Then the mc dev plugin i not for you

[stuck oasis]

Wait what you mean by dependency manager

[lost matrix]

maven/gradle

[stuck oasis]

Ah yeah I made it in maven

[lost matrix]

How do you compile it?

[stuck oasis]

Building it with the artifact I made so I get the .jar file

[lost matrix]

So you just ignore maven and everything in the pom.xml
Dont use maven if you dont have quite a bit of experience with plain Java.
Here is a guide on how to build a spigot plugin from scratch without maven/gradle:
https://www.spigotmc.org/wiki/creating-a-blank-spigot-plugin-in-intellij-idea/

[rough drift]

@lost matrix its an intellij plugin, they just choose "spigot plugin" and it generates everything for them, then all you do is go to maven -> LifeCycle -> package

[stuck oasis]

I was so stupid that I built the plugin to .jar with an artifact and didn't remember I can do the same thing in maven lol

But I think my console is still saying that "can't find main class"

[rough drift]

can you send the built jar file

[lost matrix]

I know. But he should not use mc dev without prior maven experience.

[rough drift]

why?

it does everythin for them

[brave sparrow]

That’s the issue

[lost matrix]

Exactly

[brave sparrow]

They don’t learn

Lmao

[unreal quartz]

Don’t use a tool which simplifies processes for you if you don’t know the process

[vocal cloud]

Usually when the main class can't be found it's a plugin.yml issue

[rough drift]

fair

[stuck oasis]

Thanks for helping :D

[rough drift]

however if they want to make plugins only they should focus on learning plugins then maven imo

[stuck oasis]

I had wrong file in plugin.yml

[vocal cloud]

Mhm

I know

[rough drift]

wait

nvm

[golden kelp]

How to give the player 40 hearts for 10 minutes?

[rough drift]

ig give them a health boost effect lmfao

[vocal cloud]

By giving them 40 hearts for 10 minutes

[golden kelp]

LOOKS LIKE THE FLOOR HERE IS MADE OUT OF FLOOR

[rough drift]

Nah its made out of health boost

[golden kelp]

ok man

but for real can anyone tell me?

[rough drift]

yeah use health boost effect

[golden kelp]

and how do I turn it off after 10 minutes?

[vocal cloud]

By giving them 10 minutes of the effect?

[golden kelp]

oh

forgot

NOW I KNOW WHY U GUYS WERE TALKING LIKE THT

i thought u couldnt specify time

[tribal holly]

Hi i have register a custom enchant but i have only the glow effetc on the item, is there any way to display the new enchant in enchant vanilla list ? or did i need to handle this by myself with lore ?

[blazing scarab]

manually

[tribal holly]

hmmmm

[blazing scarab]

custom enchantments are unsupported

[tribal holly]

hmmmmmmmm

is there an event when an enchant of an item is changing ?

[mint mesa]

do I come here for help on essentials not hooking into my project?

[shrewd sentinel]

'x()' in 'net.minecraft.world.entity.EntityInsentient' clashes with 'x()' in 'net.minecraft.world.entity.EntityLiving'; attempting to use incompatible return type

public class CustomMob extends EntityZombie {

    public CustomMob(Location loc) {
        super(EntityTypes.be, ((CraftWorld) loc.getWorld()).getHandle());

        this.b(loc.getX(), loc.getY(), loc.getZ());

    }

}

[delicate lynx]

that version doesn't exist on the repo anymore I believe (bstats 1.8)

[tender shard]

is there a way to check if a player is "still" mining a block?

PlayerInteractEvent fires when a player starts mining

BlockBreakEvent is called when it's done

but if they keep pressing the mouse button...

[tender shard]

you MUST use mojang mappings

[tender shard]

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

[rough drift]

question

is the command map always the same

[tender shard]

yes

[rough drift]

alright

then i can just get it once

[mint mesa]

So theres no fix for it sadly?

[rough drift]

right?

[tender shard]

sorry pls repeat your question

[shrewd sentinel]

Do not understand it. I'll search on it

[delicate lynx]

I was replying to someone else

[tender shard]

read the blog post pls

[tender shard]

whoops sorry

[glossy venture]

https://wiki.vg/Protocol#Player_Digging

[tender shard]

wrong reply

ugh I am stupid today

[tender shard]

thanks but I need it to work without packets

[glossy venture]

hm

[tender shard]

I am looking for something like... player.isMining() lol

probably doesn't exist

[rough drift]

Store a hashmap of players when playerinteractevent is sent, on blockbreakevent or on cancel remove the player from the hashmap

and when they leave also remove them

[tender shard]

yeah but that won't help

[rough drift]

why not?

[glossy venture]

but we dont know how to detect cancel

[tender shard]

okay wait I'll try to explain what I need it for

[glossy venture]

at least without packets

[tender shard]

https://www.spigotmc.org/threads/besttools.451657/page-6#post-4360403

[rough drift]

yeah that might be best xD

[tender shard]

so tl;dr

my plugin switches to the proper tool when attempting to mine a block

it should switch back to the previous when a player is finished with mining

[rough drift]

uhhhhhh

[tender shard]

if I just switch back on blockbreakevent but they are still mining, I'm fucked

[glossy venture]

why cant you use packets

[tender shard]

well I COULD and it would be the last resort

[rough drift]

lemme think, because i know there is something to detect it

[tender shard]

but I'd love to do it without

because I don't want to have protocollib as dependency

[glossy venture]

i think it might be the only option

[glossy venture]

you technically dont have to

[tender shard]

yeah sure, it'd be just "either install protocollib or not have that feature"

[glossy venture]

register a channel listener to the netty channel pipeline

[tender shard]

oh

yeah

but

I've never done that

[rough drift]

its easy ish

[tender shard]

and have no idea about how netty works

[rough drift]

lemme send you the code for it

[glossy venture]

i think you need to do it per player

and when they join

[tender shard]

that would be nice

[rough drift]

yep

and also unregister it

when they leave

lemme open the project

[glossy venture]

ike make sure to tag him cuz hes in #bot-commands lmao

[rough drift]

ChannelDuplexHandler channelDuplexHandler = new ChannelDuplexHandler() {
  @Override
  public void channelRead(ChannelHandlerContext ctx, Object obj) throws Exception {
  // Obj is your packet, you need NMS to get the packet list
  super.channelRead(ctx, obj); // Remove to cancel the packet
  }
};
((CraftPlayer)player).getHandle().playerConnection.networkManager.channel.pipeline().addBefore("packet_handler", "your_handler_name", channelDuplexHandler);
```On Join ^

```java
Channel channel = ((CraftPlayer)player).getHandle().playerConnection.networkManager.channel;
channel.eventLoop().submit(() -> {
  channel.pipeline().remove("your_handler_name");
});
```On Leave ^

IIRC its that

@tender shard

Also I have a question, how'd you put hyperlinks in your signature? (so not https://website.com but Website)

[glossy venture]

signature?

[lost matrix]

Am i seeing bootleg protocollib?

[glossy venture]

oh on spigotmc

[rough drift]

You are seeing the most epic of protocol handling in action

[tender shard]

awesome, thanks!

[rough drift]

np

[tender shard]

what signature?

[rough drift]

the thing in the spigot forums

under your post

there's a DISCORD image with some other links

[tender shard]

isn't there a button to add links?

[rough drift]

Yeah but for me they always appear as full links

[lost matrix]

There is only one external plugin in use for my projects. And that protocollib. I think its well written.

[tender shard]

I just click on the one right of the A

if that doesn't work, click on the "wrench" symbol and use BBCode

e.g. my signature is this:
