[wet breach]

without the need of having all of them

[robust portal]

^

[flint coyote]

Well you can still access the index of the list if you want a specific one

[wet breach]

yes but you need to still pull all of the list

[robust portal]

This is where I've gotten
Which outputs this

[flint coyote]

The list is "pulled" onEnable anyway. Configs are cached

[robust portal]

It's updating all of them.

[wet breach]

not saying your way is incorrect just pointing out the advantage of the other way

[flint coyote]

Yeah you don't have a section. You have a list

[wet breach]

yes in config, but they are not an object

[flint coyote]

So you have to update a list index

[flint coyote]

They are a LinkedHashMap<String, Object>

[wet breach]

still an object that isn't created automatically

[flint coyote]

I think it is actually however I could be wrong about that. I'd imagine the caching is object based and not string based

[zealous comet]

How I can create a list for if (block.getType() == ) { for all sign exist on minecraft ?

[remote swallow]

use tags

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/Tag.html#ALL_SIGNS

[zealous comet]

Tags ? Sorry Im new in Java ^^'

[remote swallow]

i can copy and paste correctly, totally

[flint coyote]

questionable link lmao

[zealous comet]

😂

[remote swallow]

just realised theres an ALL_SIGNS

so Tag.ALL_SIGNS.isTagged(block.getType())

[remote swallow]

i was just telling someone to watch it

tom scott is in it

[zealous comet]

So I do if (Tag.ALL_SIGNS.isTagged(block.getType())) ?

[remote swallow]

yeah

[zealous comet]

Ok thanks you !

[robust portal]

It's updating all of them.

Instead of making a new one

[remote swallow]

ConfigurationSection section = ...;
int nextInt = section.getKeys(false).get(section.getKeys(false).size)) + 1;
//set 
``` could probably save the key value i just cba to type it out

[lost schooner]

https://minecraft.fandom.com/wiki/Item_repair are there any items missing from this for newer updates?

[remote swallow]

or even just do getKeys(false) .size + 1

[robust portal]

@remote swallow

[rare rover]

okay

so

i got this doodoo code dont worry ima redo it

@Override
    public void run() {
        Map<UUID, Map<Material, List<PlayerGenerator>>> generators = GeneratorHandler.getPlayerGenerators();
        generators.entrySet().stream()
                .filter(entry -> Bukkit.getPlayer(entry.getKey()) != null)
                .forEach(entry -> {
                    Map<Material, List<PlayerGenerator>> playerGenerators = entry.getValue();
                    playerGenerators.forEach(((material, playerGenerators1) -> {
                        final int size = playerGenerators1.size() - 1;
                        final PlayerGenerator generator = playerGenerators1.get(size);
                        final Location location = generator.getLocation().clone().add(0, 0.6, 0);
                        final ItemStack item = getFormmatedItemStack(generator, size);
                        Bukkit.broadcastMessage(item.toString());
                        new BukkitRunnable() {
                            @Override
                            public void run() {
                                Item i = location.getWorld().dropItemNaturally(location, item);
                                i.setVelocity(new Vector());
                            }
                        }.runTask(plugin);
                    }));
                });
    }``` whenever the map is at 1 item it wont drop anything. `item.toString()` shows `COBBLESTONE` which is right but whenever i do `Bukkit.broadcastMessage(i.toString())` on the other thread it wont drop. It only works if there's 2 or more things in the map

and i can't figure it out

[dry forum]

whats the most efficent way to make an armorstand move along a certain block? ill probably have quite a few armorstands

[robust portal]

@remote swallow

There's gotta be a better way to do what I'm doing.

[zenith gate]

does anyone know of a resource on formating the data from this minecraft command: /data get entity ToastARG. Holds all the data on the player including the PDC and I need to look through it all, but it looks like shit and cant read it.

[tender shard]

use a List<Map<String,Object>

then retrieve it using getMapList

[zenith gate]

nvm, google docs works pretty well ish.

[opal juniper]

is it not just nbt @zenith gate?

[lost schooner]

Why is my IntelliJ crashing every 20-30minutes completely randomly

[robust portal]

Got an example for that, i have no idea what that does tbh. what is that and what is it called

[robust portal]

Getting the same issues

[zenith gate]

idk i think idk what nbt data looks like lol.

[orchid trout]

uninstall minecraft development and 2 bytecode related plugins that i forgot the names of

[opal juniper]

yeah, i’m pretty sure you are looking at the SNBT data

there are probably online viewers for it

[orchid trout]

you cant run bukkit methods in an async environment

[hazy parrot]

where is he running smth async ?

he is syncing it with main thread infact

[lost schooner]

[16:18:28] [Server thread/INFO]: Left enchantments: {}
[16:18:28] [Server thread/INFO]: Right enchantments: {}

Why is leftEnchantments == rightEnchantments evaluating to false

[orchid trout]

he said whenever he does Bukkit broadcastMessage it wont drop

[lost schooner]

They're both Map<Enchantment, Integer>

[young knoll]

.equals

[lost schooner]

What is the difference between them

[orchid trout]

== compares instances

[hazy parrot]

one is checking reference, and other values

[young knoll]

== compares memory location, .equals can be overridden to compare values

[lost schooner]

Should I always be using .equals for stuff

[opal juniper]

not always

[hazy parrot]

if you want to check if its same value, yes, if you want to check if its same object no

also you probably already figured, but you can't call .equals on primitives

[vapid raft]

Hey, I'd like to ask if this is a correct way to check someone's inventory
player.getInventory().getSize(), because despite if a player has something if his inv is empty, it outputs 41

[quaint mantle]

how do I get a NMS BlockState from a Material since byId is depprecated?

[hazy parrot]

because player inventory always have 41 slots

what exactly you want to check

[vapid raft]

If a player has something in his/her inventory

In other words, if it's empty

[orchid trout]

a player object doesnt have pronouns

[hazy parrot]

there is Inventory#isEmpty

[vapid raft]

Player as in the living thing behind the screen, but sure xD

[vapid raft]

Thanks

[robust portal]

still need help with this if anyones got any idas

[hazy parrot]

configurationSection called "nextInt" doesn't exist

[orchid trout]

why are you setting nextInt to nextInt?

and why are you looping through spawner.getKeys(true) and in the loop checking if spawned.getKeys(true) contains the current key

thats just r
redundant

[robust portal]

@hazy parrot How would I make it exist then?

Because this isnt working then

[robust portal]

Im essentially trying to save a spawners coord when a command is ran to prevent players from setting it twice

[remote swallow]

set(nextInt + "x"

[robust portal]

When I start dealing with configs I lose brain cells

[remote swallow]

calling set(nextInt, nextInt) wont make a config section

[robust portal]

Ahhhhh

How would I make on then

[remote swallow]

there isnt really a need for it, just call spawner.set(nextInt + ".x", value)

[robust portal]

Ohhhhh

vvvvvvvvvvvvvvvvvvvvvvvvvvvvvv

Well it almost worked

[remote swallow]

i missed a dot

.x not just x

[robust portal]

Almost money agan

I think its looping to many times?

[remote swallow]

check ur code

[robust portal]

Sorry for the spoon feeding smh

[remote swallow]

you do it every loop

why are you even looping

public void saveNewSpawner(FileConfiguration config) {
      ConfigurationSection section = config.getConfigurationSection("spawnerlocations");
      int nextId = section.getKeys().size() + 1;
      spawner.set(stuff);
      save
}

[robust portal]

Ah truth be told I dont know lol I thought that was the only way to check ids

[quaint tapir]

how do I add an enchant to an item that isn't usually enchantable
FOR EXAMPLE: a stone block

[worldly ingot]

ItemMeta's #addUnsafeEnchant() should work fine

Sorry, just #addEnchant()

[young knoll]

Set the final param to true

[robust portal]

Works perfecylt thank you @remote swallow

[dull schooner]

hey, i made a plugin on paper, but my server is using spigot, can i use it anyway?

[robust portal]

@remote swallow Okay epic final question

How would I check if it exists at any of those locations

This is what I got

[wet breach]

Possibly. If it uses paper specific api then no

[dull schooner]

the thing is, i tried loading in but it gave me an error, while in a paper server it worked just fine

and i dont remember using any specific paper api

[young knoll]

Then it probably uses paper specific api

[dull schooner]

let me see

lol, i got a class from paper imported automatically

i thought paper made compatibility to and from spigot

[remote swallow]

paper supports spigot plugins

[robust portal]

Epic would that be a cause of looping through everything?

[remote swallow]

if you need to check if its in it you might as well just save a list of locations

[robust portal]

Wdym

[remote swallow]

a List<Location>

[robust portal]

Well fuck how would I do that than

Again, very very new to coding plugins.

[dull schooner]

so, enchant name and level are the item lore, right?

can i change them while i'm enchanting?

[robust portal]

Do you have guide or something on stuff like that you can link me

[remote swallow]

set("spawnerlocations", list)

getList

[robust portal]

How would I create a list

[remote swallow]

new ArrayList

?learnjava

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

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

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

[remote swallow]

lists are probably one of the most common things you should know

[robust portal]

Something like this?

[remote swallow]

List<Location> locations = new ArrayList<>()
locations.addAll(config.getList("spawnerlocations"));

locations.add(block.getLocation)

[robust portal]

Ahhh

[remote swallow]

are you making custom spawners

[robust portal]

Kinda

[remote swallow]

just add the mob type to the pdc and handle spawning like that

[robust portal]

wat

Persistant Data Holders huh

So I pretty much just overcomplicated the fuck out of this huh

[remote swallow]

pretty much

[robust portal]

Spawners considered a tile entity yeaH?

[young knoll]

yes

[robust portal]

Alrighty, I think I've got it besides checking it?

@remote swallow Thank you so fucking much
@vivid cave Thank you so fucking much

[ornate patio]

I'm trying to boost a potion's level but for reason meta.hasCustomEffects() is always false

PotionMeta meta = (PotionMeta) holding.getItemMeta();
meta.getPersistentDataContainer().set(new NamespacedKey(plugin, "boostAmount"), PersistentDataType.INTEGER, multiplier);

// Boost effect level of potion
if (meta.hasCustomEffects()) {
    for (PotionEffect effect : meta.getCustomEffects()) {
        int newAmplifier = ((effect.getAmplifier() + 1) * multiplier) - 1;
        meta.addCustomEffect(new PotionEffect(effect.getType(), effect.getDuration(), newAmplifier), true);
    }
}

holding.setItemMeta(meta);

any ideas? I tried messing with getBasePotionData:

PotionType potionType = meta.getBasePotionData().getType();
if (potionType.isUpgradeable()) {
    meta.addCustomEffect(new PotionEffect(potionType.getEffectType(), ????), false);
}

But how am I supposed to get the original duration and amplifier?

[dull schooner]

Does anyone know if it's possible?

[young knoll]

Yes but you would have to hide the original enchantments and then add your own to the lore

[dull schooner]

Cause i want to remove that enchant.level n

[worldly ingot]

Well, at least in that case you can create a resource pack to add new entries

[dull schooner]

Oh thats fine, i just need to edit, thanks

[robust portal]

Dude persistant data containers are fucking awesome

[dull schooner]

wdym

[ancient plank]

PDC epic yes

[dull schooner]

so, i somehow managed to hide the enchantments, but i dont know how to place another text in their place

[young knoll]

You hide them via ItemFlags

You can recreate them with basic lore

[dull schooner]

Im struggling with the recreation, how do i do that?

[remote swallow]

add gray lore to the start of the lore list if it has or, or a new list

[dull schooner]

I made an list with a text components, and insert a string, but that didnt change anything

[young knoll]

Yeah you just add grey text to the top of the lore

[dull schooner]

im trying the following, but's not working
ItemMeta meta = item.getItemMeta();
@Nullable List<Component> lore = item.lore();
if(lore == null){
lore = new ArrayList<>();
meta.addItemFlags(ItemFlag.HIDE_ENCHANTS);
Map<Enchantment, Integer> enchants = item.getEnchantments();
for(Enchantment enchantment : enchants.keySet()){
String enchantName = enchantment.getKey().toString();
int enchantLevel = enchants.get(enchantment);
lore.add(Component.text(enchantName +" "+ enchantLevel));
}
item.lore(lore);
item.setItemMeta(meta);
}

it just dont give any lore at all

[young knoll]

You’re also only adding it if lore is null

It’s possible it already has lore

Or paper api returns an empty list rather than null, who knows

[dull schooner]

it is null

[remote swallow]

if (lore == null) lore = new ArrayList<>()

[young knoll]

I’ll do ya one better

[dull schooner]

that's what i have done here

[remote swallow]

no

you check if its null and cause an npe

[young knoll]

List lore = meta.hasLore ? meta.getLore : new ArrayList

[remote swallow]

shush

[dull schooner]

wow, i didnt knew that method

it's deprecated

[young knoll]

What’s deprecated

[dull schooner]

a method or class that was replaced by another

[drowsy helm]

lmao he means which method

[dull schooner]

but they dont delete from the code

he deleted the message

[remote swallow]

you are in the spigot discord

you are using the paper api

[dull schooner]

setLore()

[remote swallow]

you are in the wrong place

[young knoll]

I think it’s just lore in their api

[dull schooner]

everything from spigot i can use in paper, idk why would that be the case

[young knoll]

Also I didn’t delete anything

[wet breach]

Either ignore the deprecation to maintain compatibility or use paper specific api only

[remote swallow]

you are using paper methods, we cannot help with paper methods, if you want to use paper api go to paper discord or stay here and use spigot api

[wet breach]

Just because it is deprecated doesnt necessarily mean unusable

But yeah the above

[dull schooner]

if you want me to go, i can go 😔

[remote swallow]

im just directing you to the correct place for support

[eternal oxide]

Build against Spigot API and your plugin will run everywhere. Build against Paper and your plugin only runs on Paper

[dull schooner]

im jk

[dull schooner]

yep, thats a good point

[ancient plank]

you can also read deprecation messages, they typically tell you why something is deprecated :)

[dull schooner]

usualy its because they implemented another method that does the same thing

[ancient plank]

i.e. a lot of methods on the paper api are deprecated because they have changed to use components instead of strings

[dull schooner]

i asked there and someone said i need to use datapacks for client side

i dont think that's a real answer

[remote swallow]

what would you need that for

[young knoll]

Datapacks aren’t even a client side thing

[dull schooner]

i asked how to rename enchantments, and an admin said "Only with a use of datapack which should be installed by a client"

[dull schooner]

yep, thats what i was thinking

thats why i think that cant be a real answer

[remote swallow]

im gonna take a while guess and say they meant resource packs

[dull schooner]

even if it was

that's just impracticable

[remote swallow]

server resource packs

[dull schooner]

in several servers some items have a lot of custom enchantments, i think that surely is a way to do that

[remote swallow]

yeah, with lore

or custom resource packs

[dull schooner]

but its asked when you join, if you dont use it the items keep the custom names and custom enchantment names

[remote swallow]

so force the resource pack

[young knoll]

Or just

Get the lore working

[dull schooner]

im searching everywhere and i cant find the answer 😔

everything that i try just doesnt work

[wet breach]

You could use some trickery possibly with nms. Not entirely sure. At minimum can make use of lore

[echo basalt]

?? why's it not finding papi

fuck gradle

not even scanning the repo

I'm fuckin blind lmao

[orchid gazelle]

Use maven

[blazing flare]

How does runTaskAsynchronously work precisely? Does it create a new thread each time, reuse an existing thread that isn't main thread if one is available, does it use the main thread at times, what's the dealio?

[drowsy helm]

Never uses the main thread. Iirc it creates a new thread then discards it as soon as it’s done

You might be able to rummage around the bukkit scheduler src and see how it does it

[wet breach]

It uses a thread pool to execute tasks. So it will create a thread if necessary but it wont necessarily get a dedicated thread to itself

Unless its the only task needing to be run lol

[buoyant viper]

not even trying the repo

[quiet ice]

Repost of yesterday's question of mine:
Is anyone aware of some library that basically does regex on steriods? i.e. I'm looking for something that can evaluate something like follows:

{
  "priority": 100, 
  "validFor": {
    "locales": ["DEU", "FRA"],
    "patternMatches": "[\d\.]+(,\d+)?[KMGTY]?"
  },
  "value": {
    "pattern": "([\d\.]+)(?:,(\d+))?([KMGTY]?)",
    "transform": [
      {
        "validFor": {
          "ifNotPresent": ["{2}"]
        },
        "data": "0",
        "store": { "variable": "{2}", "as": "STRING", "via": "STORE" }
      }, {
        "concat": [ "{1}", ".", "{2}" ],
        "store": { "variable": "ret", "as": "DECIMAL", "via": "ADD" }
      }
    ],
    "return": "ret"
  }
}

I know, cursed beyond belief but without some cursed combination of sscanf (which would require the FFI anyways) and regex it is hard to do otherwise
Needn't be JSON and can also be another file format.

[blazing flare]

AHH a pool ok. That's okay. I know creating threads is supposed to be a little expensive but a pool is beneficial. Thank you, both.

[astral laurel]

I want to make a gun but what I have won't work can you help me?

     Vector vec =  player.getEyeLocation().getDirection();
                        for(Player players: Bukkit.getOnlinePlayers()){
                            if(players.getLocation().getDirection().equals(vec)){
                                players.damage(2);
                            }
                        }```

[maiden thicket]

check for targetentities from the player

there is a method for that

[astral laurel]

how can i do that? (i don't find "targetentities")

[maiden thicket]

i swear there was a getTargetEntity but i may be tripping nvm then

[drowsy helm]

https://bukkit.org/threads/get-entity-player-is-looking.300661/ check out this thread

the code you made will try and match any player looking in the same direction as the current player. It logically doesnt make sense

[lost schooner]

Does Java have any way to define custom methods on external types other than using a newtype pattern

[astral laurel]

thanks

[drowsy helm]

as in extending functionality?

[lost schooner]

yes

[drowsy helm]

no

[lost schooner]

😡

[drowsy helm]

other than extending it theres no way

[lost schooner]

Wdym extending it? Don't you have to extend in the original class def

Or can you extend interfaces in your own code

[drowsy helm]

yeah ofc

what are you trying to do?

[lost schooner]

Implement methods on ItemStack so I don't need a bunch of dangling static functions everywhere

[drowsy helm]

just use a util class

[lost schooner]

Well that's what I'm doing but it's getting mega bloated

I can refactor but idk

[drowsy helm]

sub util classes lol

[lost schooner]

where is my impl Trait

How do I figure out if an item is being renamed in an anvil? It seems the normal way to do this is to check the result item but if I'm trying to determine the result item how do I check for it?

[drowsy helm]

like they are actively typing the name in?

[vital yacht]

Kotlin does

[lost schooner]

I suppose so, just an event handler for PrepareAnvilEvent

[drowsy helm]

yeah PrepareAnvilEvent is pretty much all you have

[lost schooner]

If only Spigot had a Rust API ;-;

[drowsy helm]

you can do a packet listener aswell

[vital yacht]

There’s something even better than Rust called Skript

[drowsy helm]

https://github.com/MitchGB/MinecraftEnhanced/blob/main/src/main/java/com/buoobuoo/minecraftenhanced/core/event/listener/AnvilRenamePacketListener.java
I did this a bit ago with protocol lib

[lost schooner]

But do you see how this becomes an issue, where I'm basically relying on the functionality remaining unchanged in order to reimplement the functionality?

[drowsy helm]

yeah ig

[vital yacht]

Wdym relying on the functionality to remain unchanged?

[lost schooner]

The anvil has its normal functionality which includes renaming items

You type a new name, the result becomes the left item with that name

However, when you're trying to figure out whether the user is trying to rename the item, you all of a sudden have to rely on the original functionality to reimplement itself

Because you can only check the name of the result item

There is no API call to query the name box

[vital yacht]

Can’t you check the name of the first item? I don’t get what you mean

[lost schooner]

You can check the name of the first item but you cannot determine what is in the name box

I would send an image but I cannot

[drowsy helm]

look at the link i sent

it does exatly that

[lost schooner]

The closest you can get to this is by checking whether the left input item has the same name as the result item, if they are different then the result item is the name the user typed in

[drowsy helm]

https://twitter.com/BubyDev/status/1553268011100176385

[lost schooner]

I am not sure how the code works, not to say it doesn't but I try to avoid using code that I don't understand

[drowsy helm]

its a packet listener

whenever the player types something in, a packet is sent

[lost schooner]

I don't know where it would go or anything

This is my second day doing plugin development

[drowsy helm]

gotcha

[vital yacht]

What’s the issue with that? Is it not updated when the user types?

[lost schooner]

I used to know Java but I forgot it over time

[lost schooner]

It is, but it is not possible to query without a packet listener, apparently

[drowsy helm]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/inventory/AnvilInventory.html

has a getRenameText method

[lost schooner]

Whoah

Nice

That worked. Thanks a bunch

[orchid gazelle]

Can I somehow force-open the chat for a player?

[drowsy helm]

no

[orchid gazelle]

Or is it clientsided

oof

[drowsy helm]

you trying to force text input?

[orchid gazelle]

Yes

[drowsy helm]

yeah the closest you can get to that is a sign input ui

thats about it

[vital yacht]

What are you trying to do specifically?

[orchid gazelle]

But having to click on a rename field on an anvil and then having go click the item is... annoying as hell

[orchid gazelle]

Idk imma implement it into my system because I just saw Anvil Things in this chat and that reminded me

[orchid gazelle]

Wait sign input field?

Can I confirm with enter?

It switches the line with enter, but is that detectable?

[drowsy helm]

nah pretty sure they have to click it still

[orchid gazelle]

Thats sad

[drowsy helm]

unless a packet is sent for each keystroke

dont think it is

[orchid gazelle]

well maybe for line switched

But I don't know thaaat much about packets

[drowsy helm]

yeah no its sent as one chunk in a packet

so no way to detect enter being pressewd

[orchid gazelle]

Well but at least I can customize the UI right?

[drowsy helm]

with a resourcepack, yeah

[orchid gazelle]

With a resourcepack

Yeah

Alright thanks

[vital sandal]

I came into this err :l

for some reason it shows that

tried Invalidate Caches but no luck

[tender shard]

show the full error

click the uppermost item on the list, then select everything from the console output and paste it

[fluid river]

yo guys

what u think about Penistone problem

jree fava

[vital sandal]

just change to ultimate version :l

and it work for some reason

[quiet ice]

Good luck, you'll wait a lot longer than that

any way to decode these characters?

[flint coyote]

128 char cap of what?

[icy beacon]

better yet, any way to make cmd actually show them properly?

[flint coyote]

I see

[paper cosmos]

I can't fix this problem when building spigot server. I downloaded the file both pom and jar and put it in the work folder but it still gives me this error and can't see I downloaded it manually

[ERROR] Failed to execute goal on project spigot: Could not resolve dependencies for project org.spigotmc:spigot🫙1.20.1-R0.1-SNAPSHOT: Failed to collect dependencies at com.mojang:authlib🫙4.0.43: Failed to read artifact descriptor for com.mojang:authlib🫙4.0.43: Could not transfer artifact com.mojang:authlib:pom:4.0.43 from/to minecraft-libraries (https://libraries.minecraft.net/): Connection reset -> [Help 1]
What can I do? I have a bad internet but I can't fix it any time soon

[flint coyote]

Can you use mobile data?

[icy beacon]

fixed by adding chcp 65001 (change code page to utf-8) in the beginning of the startup script

[paper cosmos]

no why

[drowsy helm]

When you say downloaded do you mean through build tools

[flint coyote]

could have been more reliable

[paper cosmos]

no, manually from libriries minecraft net

[eternal oxide]

did you install the authlib to your local maven repository?

Did you manage to download it manually?

[left depot]

How long can it take until spigot updatechecker api updated?

[tender shard]

which one do you mean? the legacy one, or the new one?

the "new" one is basically instant

[icy beacon]

4 hours spent to figure out that i confused -= and =-

[glad prawn]

I want to prevent people from dropping a specific item, is it reasonable to use PDC for this?

[sullen marlin]

sure

[shadow night]

If you want it to be different for each player or be able to give any item that tag, then yes. Otherwise you could just add a config or something.

[glad prawn]

ok tks

ok tks again

[kind prawn]

what's the right way to log errors to console?
I don't want to pass the plugin to each class should I create functions for logging?

[shadow night]

You could make the logger static or just System.out.println() ig

[left depot]

got the legacy yeah

[tender shard]

the legacy one, idk. why don't you use the new one?

[left depot]

yeah good question 😂

[tender shard]

https://api.spigotmc.org/simple/0.2/index.php?action=getResource&id=%s parse that to json, there shuold be a string named "version"

[steep plaza]

hi

guys i have one qestion

how i can get player name

[chrome beacon]

Player#getName

[steep plaza]

with #?

[chrome beacon]

No

[steep plaza]

beacause i need i get a player name for put in a scoreboard

[tender shard]

then just call getName() on the player object

[steep plaza]

okok thx

[quaint mantle]

chcp 65001 >nul

[steep plaza]

Score score = objective.getScore(ChatColor.WHITE + Player.getName() + 1);
it gives me an error under getName

[undone axle]

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

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

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

[tender shard]

you don't know the basic stuff, e.g. difference between classes and objects/instances of classes

obviously, getName() is not a static method, it wouldn't make any sense

[tender shard]

check out one of these tutorials

[steep plaza]

ah okok

[tender shard]

you need to have an object of player, a specific player

[steep plaza]

AHAHAHAH im so stupid

sorry

but is my first time

[tender shard]

np lol

[steep plaza]

@tender shard its work

[upper hazel]

Who knows how to implement a 2nd place for a passenger in a horse? like in this plugin
https://www.spigotmc.org/resources/twoplayerhorseriding.89058/

[chrome beacon]

That plugin is open source

[icy beacon]

it uses packets magic somehow

yep

[chrome beacon]

You can take a look

[alpine urchin]

he’s afraid of packets

[icy beacon]

oh i remember this dude

he was trying to serialize an entire horse yesterday

of course he is afraid of packets

[young knoll]

They are just keeping an armorstand synced with the horse

[tender shard]

imho all packet libraries have the wrong name. ProtocolLib, PacketEvents... They should be called Customs!

[icy beacon]

and some packets

for some reason

lol

[tender shard]

Customs deals with incoming and outgoing packets all day, why is no library called customs

[icy beacon]

what is this witchcraft

[icy beacon]

make your own

😄

but if we are serious

those libs just want to be descriptive

if i saw a lib named "customs" i would think of custom items, enchantments, entities

[tender shard]

nah I'll play KFC simulator

[icy beacon]

def not packets

[icy beacon]

that's also a good idea

[upper hazel]

i bad read not my code (

[icy beacon]

unfortunate

[young knoll]

The only packet usage seems to be hiding the passengers from eachother

[icy beacon]

oh

[young knoll]

Presumably because they would block your view

[icy beacon]

couldn't you just do that with bukkit api

player.cansee(player)

or smth

[young knoll]

Yes

[icy beacon]

then why is this with packets 😭

[tender shard]

that was added in 1.19.X

[icy beacon]

actually?

i thoguht it was there for a very long time

[young knoll]

It is

[orchid gazelle]

ho lee

[icy beacon]

nvm that's a getter lol

1.12.2 has this getter

actually wait

https://hub.spigotmc.org/nexus/service/local/repositories/snapshots/archive/org/spigotmc/spigot-api/1.12.2-R0.1-SNAPSHOT/spigot-api-1.12.2-R0.1-20180712.012057-156-javadoc.jar/!/org/bukkit/entity/Player.html#hidePlayer-org.bukkit.plugin.Plugin-org.bukkit.entity.Player-

1.12.2

hides a player from this player

[young knoll]

Yeah it’s been around forever

[icy beacon]

alex you lied to me how coudl you

[tender shard]

oh then it was hideEntity

idk

[young knoll]

Yes hideEntity is new

[soft hound]

Would it be better to make my own economy plugin or just use Essentials since there's a lot of plugins supporting it ?

[chrome beacon]

Most plugins support it through Vault

If you want your own econ plugin make it support vault

Anyways I'd just use Essentials

[soft hound]

Why is Vault so special ?

[eternal oxide]

I'd just implement Vault and let the server choose what eco they use

[chrome beacon]

I'd the standard API for Economy plugins

It's been around for years

[paper cosmos]

I just put in work folder in my buildtools folder

[eternal oxide]

wrong

[paper cosmos]

yes, I have jar and pom files of this lib

where?

[eternal oxide]

you need to instal it to your local maven

[paper cosmos]

how does it look?

[eternal oxide]

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

[paper cosmos]

except for the path to file I dont know what these fields are

[soft hound]

is it posible to do it through maven ?

https://github.com/MilkBowl/VaultAPI

Would this be it ?

[icy beacon]

is this pdc or nbt?

i mean can i remove this using pdc or should i use nbtapi

[eternal oxide]

public bukkit values is pdc

[icy beacon]

[torn shuttle]

hey nerds, remind me real quick, if I want to teleport a player when they get on should I do the player login event or the player join event?

[eternal oxide]

join

and teleport 1 tick later with runTask

[torn shuttle]

thanks, just this once I won't take all of your lunch money

[worldly ingot]

PDC is NBT

[spare hazel]

setDamageRewards(1);
Invalid method declaration; return type required

class:
public class Combat extends Skill implements ConfigurationSerializable {

theres a setDamageRewards Method on the Skill abstract class

[worldly ingot]

Okay, so you've marked it as @Override but the method signature is wrong

Skill#setDamageRewards() has a different return type than your Combat#setDamageRewards() implementation

[spare hazel]

no i want to use the mothod i created in the abstract class

[worldly ingot]

I'm going to need to see the entirety of both classes to actually understand what you're trying to do lol

?paste ideally

[undone axle]

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

[torn shuttle]

the world creator is used even just for loading existing but currently unloaded worlds right?

or wrong?

[spare hazel]

oh nvm

[eternal oxide]

[torn shuttle]

it looks right

ok

thanks

[spare hazel]

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

[worldly ingot]

You're calling it outside of any scope

[spare hazel]

public Combat(){
setDamageRewards(1);
}

[worldly ingot]

Yep

Beat me to it

[spare hazel]

wdym?

[worldly ingot]

You're right. The constructor you just sent is what you should be doing

I suppose you have two constructors though so if you want to run it for both you can either put it in both constructors, or use an initializer block

[spare hazel]

i was just about to say that
thanks for the help btw

[worldly ingot]

    public Combat(Map<String, Object> m){
        setXp((Integer) m.get("xp"));
        setLevel((Integer) m.get("level"));
        this.setDamageRewards(1);
    }

    public Combat(){
        this.setDamageRewards(1);
    }

// OR

    public Combat(Map<String, Object> m){
        this();
        setXp((Integer) m.get("xp"));
        setLevel((Integer) m.get("level"));
    }

    public Combat(){
        this.setDamageRewards(1);
    }

// OR

    {
        this.setDamageRewards(1);
    }

    public Combat(Map<String, Object> m){
        setXp((Integer) m.get("xp"));
        setLevel((Integer) m.get("level"));
    }

    public Combat(){}

Both will work

Edited in a third actually. Second one is probably best in case you choose to add more things to the default constructor

[chilly hearth]

i have downloaded the code from github i want to compile it into a plugin iam using intellJ what do i do after importing it ?

[remote swallow]

what code

[chilly hearth]

a source code of a plugin

[remote swallow]

send the link of its github

[ionic terrace]

Is it possible to refresh the values in a GUI without closing and reopening the inventory?

[eternal oxide]

yes

[chilly hearth]

https://github.com/TeamVK/TokenEnchant

[remote swallow]

the code isnt actually on there

[chilly hearth]

oh

so i cant compile it ?

[remote swallow]

correct'

[stark patio]

Any ideas why popular plugins like LuckPerms, WorldEdit, "essentialsX, ... don't define any permissions to their commands in plugin.yml? Just courious about what the actual reason(s) could be.

[chilly hearth]

sad

[ionic terrace]

Something like setItem and then updateInventory?

[eternal oxide]

because they are bad

[chilly hearth]

bruh cuz they have given them on website

[remote swallow]

no reason to, luckperms just grabs perms from usage iirc so unless its an op only thingt here isnt a need to add them

[chilly hearth]

btw how do we add a new value in plugins ?

[remote swallow]

a new value where

[chilly hearth]

like making a plugin with a new value

[remote swallow]

what new value

[chilly hearth]

like coins for example

[remote swallow]

oh an economy plugin

just hook into valut

vault

[chilly hearth]

hm

is there an event for the new value ?

[remote swallow]

probably

[chilly hearth]

do u know the event ?

[remote swallow]

just had a look and it turns out vault doesnt have events

[chilly hearth]

so what they use

[remote swallow]

they handle it from econ responses probably

[chilly hearth]

econ response

?

[remote swallow]

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

[chilly hearth]

bruh

i still dont understand that lol

[remote swallow]

its returned when you call the add currency method

[chilly hearth]

oh you mean /pay

[remote swallow]

no, the api method

[chilly hearth]

i see

[remote swallow]

AbstractEconomy#depositPlayer(player, amount)

that returns an EconomyResponse

[chilly hearth]

so to create our own currency in a plugin we need to use their api ?

[remote swallow]

if you want it to work with most other plugins that use money sure

[pseudo hazel]

if you want to convert it back to other currencies, sure

[chilly hearth]

oh

is it allowed if we just edit it in vault plugin code and may add /withdraw

[remote swallow]

you cant add code to vault, vault is an api

you would need a plugin that hooks into vault

[chilly hearth]

alr and what about /withdraw

[remote swallow]

you make a command to hook vault and remove it from there bank, and give them something to do with said withdrew currency

[chilly hearth]

and in the code it will go like ?

[eternal oxide]

No one is writing it for you

[remote swallow]

im not spoonfeeding you it

[chilly hearth]

ah

[spare hazel]

import net.milkbowl.vault.economy.Economy;
import org.bukkit.plugin.RegisteredServiceProvider;

public class EconomyController {

    private static Economy econ = null;

    public static boolean setupEconomy() {

            return false;
        }
        RegisteredServiceProvider<Economy> rsp = HypixelSkillCore.getInstance().getServer().getServicesManager().getRegistration(Economy.class);
        if (rsp == null) {
            return false;
        }
        econ = rsp.getProvider();
        return econ != null;
    }

    public static Economy getEconomy() {
        return econ;
    }
}

[chilly hearth]

dam

[spare hazel]

replace HypixelSkillCore with your plugin name

make sure to create a way of obtaining the plugin instance

[remote swallow]

that gets current economy

if you want ur own economy its different

[chilly hearth]

thanks

[spare hazel]

u should just use essentials for the currency

also call setupEconomy in on

Enable

[chilly hearth]

Hi, the tutorial of kody simpson is good for menu handlers?

or the best is https://www.spigotmc.org/threads/a-modern-approach-to-inventory-guis.594005/ ?

[remote swallow]

deffo the forum post

[spare hazel]

kody simpson has the best youtube tutorials on spigot development.

[sterile breach]

yes that's why I'm hesitating between the 2

[remote swallow]

the forums for most stuff is always better

[spare hazel]

and a java series if you are just getting started with java

[remote swallow]

also kody simpson use inv holders which is the entirely wrong way to do it

[sterile breach]

ok down there I did kody simpson's I'm going to look at the other small question anyway, on kody simpson's when the menu is closed, it's not deleted from the list it seems to me?

[spare hazel]

is using skript bad when you know spigotapi? i know spigotapi but making a custom spawners plugin in spigotapi is too hard

[remote swallow]

use the forum post, it uses the correct way of making inventories

[remote swallow]

spigotapi is very easy, im gonna guess you probably need to learn java

[chilly hearth]

chill out lol

[sterile breach]

I have already made a spawners plugin in skript and it's a hassle

[ionic terrace]

I did it with player.getOpenInventory().setItem which seemed to work

[spare hazel]

no i dont mean leveling up spawners and... i mean a spawner that is invisible and summons the mob no matter the light level, block underneath, space available

[sterile breach]

oh no I had made a system so that when your spawner is broken you can recover it in a gui

oups sorry EpicEbic i speak to @spare hazel

[spare hazel]

admin only or also for the players?

[chilly hearth]

e

[sterile breach]

also players

[spare hazel]

doesnt seem that hard...

does skript have oop?

or json support?

[sterile breach]

the hardest part was more the page system etc... I used a var to find out which page I was on etc... I am still a beginner in the spigot api but one of my goals is to redo this plugin in spigot

[sterile breach]

csv stockage

[glossy venture]

you can reference java classes i think using skript-mirror

but I dont think it has a way to define classes

oh someone else got it

[karmic mural]

Hey. I'm working on something where I interact a lot with the inventory. I see that there seems to be 41 items when I do player.getInventory().getContents(). Is there somewhere I can read about what exactly all these slots are? I've made the assumption that this is the 36 inventory slots, + offhand + armor slots, but is this incorrect?

I did think that it could potentially be the inventory crafting grid, too, but since they can't store anything the armor slots seem more likely

I realize now maybe PlayerInventory.getStorageContents() is what I should be using, huh?

[wise mesa]

you're correct

i forget which ones are which but that is correct

[wise mesa]

there

[karmic mural]

Thank you @wise mesa @humble lynx

[humble lynx]

Depending on the event use e.getrawslot as well

[tender shard]

this is correct for Inventory.getItem(int)

getRawSlot might be different, usually that one starts to count at the top most slot - but not always lol

[humble lynx]

Yeah, using GUIs you have two separate slot numbers going on at the same time, so e.getRawSlot is a good reminder

how i cen do it :D

[chrome beacon]

You call the setter?

[young knoll]

It's also an option in the constructor

[pseudo hazel]

I wasnt talking to you, but you just need to use paste or format the code using triple backticks `

ahh i dont get it :D

[chilly hearth]

a

i have installed the plugin minecraft development in intellj but when i do new project it doesnt show me the option of spoigt it shows bukkit bungecord etc

[hazy parrot]

I think they dropped support for spigot

Anyway don't use that plugin, it's trash

Pretty sure you select bukkit and then spigot

But it defaults to paper iirc

[last sleet]

Is there a way of listening to the inventoryclickevent after it has triggered? (After everything has finished)

I am trying to add more crafts to the vanilla anvil and I need the anvil with the items in it when the players adds a new one. I could technically handle everything myself, delete items and replace them in the anvil, but there surely is a better way?

[flint coyote]

You can just run it with a 1 tick delay from a scheduler

[last sleet]

Yep I tried that

didn't seem to work...

I'm looking now into the event priority, perhaps that will work

nope it doesnt

BukkitScheduler scheduler = mainPlugin.getServer().getScheduler();
scheduler.scheduleSyncDelayedTask(mainPlugin, new Runnable() {
public void run() {
//code
}
},0);

[flint coyote]

You just create an itemStack with Material.POTION and then change the PotionMeta you can get by calling myItemStack.getItemMeta()

[last sleet]

this is the correct code for scheduling right?

[flint coyote]

Try with a 1 instead of a 0 although I'd expect that to be the same

[last sleet]

hm yea

ogh im dumb

well it works now, thanks xd

You don't unless you like malware

An unofficial explanation of the DMCA can be found here: https://www.spigotmc.org/wiki/unofficial-explanation-about-the-dmca/

Long story

[river oracle]

Use the Gui jar my link sent you to

It's a wip If you have any issues feel free to report them in the thread

It should be much easier than command line

[flint coyote]

Book formatting is such a pain

[river oracle]

Yes

[flint coyote]

At this point I'm not even trying to write pretty code and still I run into weird issues

[paper cosmos]

what is wip?

[river oracle]

Work in progress

[paper cosmos]

it might take a while to download this with my 2KB/s internet. Is it going to fix my problem with non ability to download authlib for the building?

[river oracle]

With internet that slow you probably can't download anything

You'd be hardpressed to even get paper with internet that slow

[paper cosmos]

well, normally it can reach about 50KB/s

[kind hatch]

Yikes, you'll have to download even more once you get the jar. BuildTools clones git repos so it can build everything locally.

Just combine them.

if (GG >= 0 && GG <= 19) {
  // Do stuff
}

[paper cosmos]

Do you mind getting involved in illegal business by sending me a built server jar?

[kind hatch]

Even if I was, you internet speed wouldn't download it in a fast manner. The final jar is like ~75MB

[paper cosmos]

my server folder is already 250Mb

[kind hatch]

No, but it just makes it easier to read. Plus less nesting.

[hazy parrot]

Yeah, it's probably that

[paper cosmos]

with this internet I've downloaded intellijidea with all necessary stuuf for mc plugins, minecraft, discord, and three spider man movies

this checking for secure connection on spigot site makes my life harder

I still can't see why you can't send me ready server jar

[eternal oxide]

illegal is why

[kind hatch]

It's for the same reason why spigot can't provide direct downloads.

Also, BuildTools primary purpose is to compile the server jars.
It can install the mappings via the --remapped flag, but past that, there shouldn't be any need for a manual lib import.

[hard socket]

can I show only one armor stand hand?

[paper cosmos]

How can I fix that error?

[kind hatch]

You should be able to get mojang related code through the spigot dependency. You are using maven right?

[paper cosmos]

yes, though I dont even know at which point of all this process I decide if I use maven

[kind hatch]

Maven is a dependency management tool. It removes the hassle of hunting down jar files and manually importing them.
You choose whether to use it at the start of your project.

[paper cosmos]

I don't understand what you said in the first sentence

[chilly hearth]

Shouldn't we use + there

[ivory sleet]

Can you show the error?

Nah

?paste just

[undone axle]

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

If you use maven, you'll have a dependency section that contains

  <groupId>org.spigotmc</groupId>
  <artifactId>spigot-api</artifactId>
  <version>1.18.1-R0.1-SNAPSHOT</version>
  <scope>provided</scope>
</dependency>

You'll want to use the artifiactId of spigot for usage of NMS code.

[quiet ice]

Are you sure that it is libraries.minecraft.net? https://libraries.minecraft.net/com/mojang/authlib/maven-metadata.xml shows that this artifact does not exist under the repository

[ivory sleet]

Verify and send

U select the text

And then u press enter

[chilly hearth]

?

[kind hatch]

No? If you want to check if GG is greater than 0 and less than 19, you combine the statements by using an AND check.

[chilly hearth]

So it won't work with +?

[kind hatch]

Not if you're doing a comparison like that one.

[chilly hearth]

Oh ok

[quiet ice]

Actually seems like it is just an improperly maintained repo. https://libraries.minecraft.net/com/mojang/authlib/3.17.30/authlib-3.17.30.pom works, but the maven-metadata.xml files are missing strangely enough

[paper cosmos]

I used different link to download.

[trail coral]

what do you think it is ?

[quiet ice]

What are you running the plugin with?

You know, the version of the server?

Well I guess that fixes your issue then. Glad to see you figured it out

[ivory sleet]

Idr the name for it; but in certain languages yes that’s possible true is treated as 1, false is treated as 0 and vice versa

Oh yes branched programming

[trail coral]

bro

your plugin is 1.19

you server isnt

[quiet ice]

And what is it?

[quiet ice]

They figured that out already

[paper cosmos]

You know I have no idea what you mean by this. How do I use this information to build the server?

[quiet ice]

Do a maven clean install or a gradle clean build

Also make sure you are using the right target+source/release version for your build

[eternal oxide]

CalamityScen was built for a newer java

your server is running 8

[quiet ice]

Given that you are probably using IJ: Go figure it out yourself.
For the CLI it would be mvn clean install and ./gradlew clean && ./gradlew build respectively

Under maven open the POM, click on the drop-down menu next to the "Run" button, go on "Run as..." and click "maven clean".

[eternal oxide]

in eclipse you can just use the project menu and select clean

[quiet ice]

Under gradle click on Window > Show View > Other > Gradle > Gradle Tasks.
Then execute the clean goal from there

[kind hatch]

I'm going to assume that you don't have anything setup.

1. Download BuildTools (Whether it through the link on the wiki or the link to the GUI that's in development)
2. Run it. (java -jar BuildTools.jar --rev <THE VERSION YOU WANT> --remapped)
3. Copy the completed jar to your server directory.
4. Setup your maven project and include that dependency in your pom.xml
5. Use the built in maven tools to package your plugin jar.

That's all you have to do. If you just want the server jar, stop at step 3.

[quiet ice]

That won't do much if the improper JVM version is checked out by your IDE.
Maven unfortunately has a bug in which it does not attempt to recompile classes compiled by the IDE even though the IDE built these classes for the wrong JVM

[paper cosmos]

I'm stuck on the second step. Though I always ran the BuildTools without --remapped. I don't know what it does but I'll try it

[kind hatch]

--remapped installs the remapped jars to your .m2 directory so that you can use the mojang mappings in your projects.

[paper cosmos]

How do you know all that?

[lost schooner]

How do I get the max durability on an item? I'm trying to add together durabilities but Damageable.getDamage() and Damageable.setDamage() only get how much the tool has been damaged rather than how much durability it has left

[kind hatch]

1. I keep up to date with the game and the community postings.
2. I've been working on the GUI for it so much that I know way more about it than the average person.

[buoyant viper]

just get good

[paper cosmos]

Is this Maven a part of Spigot or it is a different thing?

[kind hatch]

Completely separate. It's just a dependency management tool.

[buoyant viper]

Maven is a project management system Spigot uses

[zenith gate]

I can't get the EnchantItemEvent to trigger. the docs say Called when an ItemStack is successfully enchanted (currently at enchantment table) I am enchanting items, they are successful, but yet the event is never called upon.

@EventHandler
public void FrozenAspect(EnchantItemEvent event) {
    event.getEnchanter().sendMessage("I WAS CALLED");  
    Bukkit.getLogger().info("I WAS CALLED");
}

This is what I have and it never runs. I do have it registered.

[paper cosmos]

my brain melts when I see word dependency

[buoyant viper]

think of spigot(-api) as a dependency to ur plugin

well, dont think it just to think it, since it really is a dependency, but yeah

[paper cosmos]

you just used this word twice

also th word api

[buoyant viper]

dependency, its something ur plugin requires to compile/run

[kind hatch]

A dependency is something that you depend on.
I.E. your project depends on the Spigot API.
It cannot run without it.

[buoyant viper]

ur plugin is "dependent" on spigot-api

Spigot API is what lets ur plugin interface/use Spigot

[lost schooner]

nvm it's Material.getMaxDurability()

[ornate patio]

I'm trying to boost a potion's level but for reason meta.hasCustomEffects() is always false

PotionMeta meta = (PotionMeta) holding.getItemMeta();
meta.getPersistentDataContainer().set(new NamespacedKey(plugin, "boostAmount"), PersistentDataType.INTEGER, multiplier);

// Boost effect level of potion
if (meta.hasCustomEffects()) {
    for (PotionEffect effect : meta.getCustomEffects()) {
        int newAmplifier = ((effect.getAmplifier() + 1) * multiplier) - 1;
        meta.addCustomEffect(new PotionEffect(effect.getType(), effect.getDuration(), newAmplifier), true);
    }
}

holding.setItemMeta(meta);

any ideas? I tried messing with getBasePotionData:

PotionType potionType = meta.getBasePotionData().getType();
if (potionType.isUpgradeable()) {
    meta.addCustomEffect(new PotionEffect(potionType.getEffectType(), ????), false);
}

But how am I supposed to get the original duration and amplifier?

[young knoll]

The only thing you can really use is PotionData#isExtended() and isUpgraded()

[dull schooner]

how do i get a Player from HumanEntity?

[young knoll]

Cast it

[ornate patio]

theres really no way to get the duration or level?

[zenith gate]

i would assume the orignal would be in the getBasePotionData

docs say Returns the potion data about the base potion

[young knoll]

The duration and level for those are fixed internally

And not accesible it seems

[dull schooner]

thanks

is there any way to show a text in front of the anvil gui?

[zenith gate]

wdym infront of the gui?

[ornate patio]

thats annoying af

[quaint mantle]

How can one iterate through a chunk ?

all the locations

[young knoll]

3 nested loops

x and z are from 0 to 15 and y is from world.getMinHeight to world.getMaxHeight

[ornate patio]

I've resorted to just manually listing out all the durations and amplifiers

public enum PotionStat {
    // 180 seconds = 3 minutes
    // 480 seconds = 8 minutes
    NIGHT_VISION(PotionEffectType.NIGHT_VISION, 180, 480),
    INVISIBILITY(PotionEffectType.INVISIBILITY, 180, 480),
    JUMP_BOOST(PotionEffectType.JUMP, 90, 180, 480, 0, 1),
    ...

    private final PotionEffectType potionEffectType;
    private final int shortenedDuration;
    private final int normalDuration;
    private final int extendedDuration;
    private final int normalAmplifier;
    private final int upgradedAmplifier;

    private PotionStat(PotionEffectType potionEffectType, int normalDuration, int extendedDuration) {
        this(potionEffectType, normalDuration, normalDuration, extendedDuration, 0, 0);
    }

    private PotionStat(PotionEffectType potionEffectType, int shortenedDuration, int normalDuration, int extendedDuration, int normalAmplifier, int upgradedAmplifier) {
        this.potionEffectType = potionEffectType;
        this.shortenedDuration = shortenedDuration * 20;
        this.normalDuration = normalDuration * 20;
        this.extendedDuration = extendedDuration * 20;
        this.normalAmplifier = normalAmplifier;
        this.upgradedAmplifier = upgradedAmplifier;
    }

this is fun

[dull schooner]

@EventHandler
  public void onAnvil(PrepareAnvilEvent event){
      AnvilInventory inventory = event.getInventory();
      int levelCost = inventory.getRepairCost();
      if (levelCost > 39) {
          Player player = (Player) event.getViewers().get(0);
          ChatColor chatColor;
          if (levelCost <= player.getLevel())
              chatColor = ChatColor.GREEN;
          else{
              chatColor = ChatColor.RED;
          }
          List<String> lore = new ArrayList<>();
          lore.add(chatColor + "Enchantment Cost: " + levelCost);
          ItemStack tempItem = inventory.getResult();
          if (tempItem != null) {
              tempItem.setLore(lore);
              inventory.setResult(tempItem);
          }
      }
    }```
Why isnt this working?

[quaint mantle]

how can I get the exact location tho not just the 0..15 ?

[young knoll]

Do you need the exact location?

[quaint mantle]

Yes I do

[young knoll]

Because Chunk has methods that take releative location

[quaint mantle]

I do need exact locations

[young knoll]

Either way you should just have to multiple the chunk x and z by 16

And then add your 0-15

[ornate patio]

this wont work for turtle master

cause it has 2 effects

damnit

[quaint mantle]

what about Y?

[sterile breach]

https://www.spigotmc.org/threads/a-modern-approach-to-inventory-guis.594005/

hello, I followed this tutorial to make my menu handler, but I find the handler "too developed". I mean, as far as click events etc. are concerned, I would prefer not to have a class inventory button but directly redefine the onCLick function in the menu itself, after that maybe it's really better and that it I just have to get used to it?

[young knoll]

Y doesn't need to be changed

[quaint mantle]

rn its 0..16?

[soft hound]

Is there an event that gets triggered when a cactus grows ?

like for example a specific "CropGrowthEvent" or something

[dull schooner]

i just need the result to show the custom lore, but as soon as the player gets it, i want it removed, but it's never showing anything

[young knoll]

x and z are from 0 to 15 and y is from world.getMinHeight to world.getMaxHeight

[ornate patio]

is it possible to get the vanilla potion duration and amplifier with NMS?

[echo basalt]

probably

Easiest way is to just loop through the potion registry and prnt out their duration and amplifiers

because it's all hardcoded

[soft hound]

Or just make a custom one ? 🙂

A quick question

I'm making a custom item, and it'll allow for it to have storage and the player to sell it.
Is there a way to make something like @EventHandler and call it from other classes, and when a player sells, it triggers ?

[river oracle]

You can make custom events

?event-api

[undone axle]

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

[river oracle]

That's just a guide generally I'd recommend if you want multiple of the same event for multiple items just use a static instance

[ornate patio]

would u happen to know how to do that

[young dome]

Hello, this error occurs when I try to make an ItemFrame entity spawn, is this a bukkit bug? I didn't find anything on web.
The cause comes from here: https://prnt.sc/hIQw8FHXAhkB
Error : https://code.alwyn974.re/bironujaxo.apache

[prime epoch]

Is it a good idea to store all the bounding boxes for peoples claims in one array?

im talking in terms of memory and stuff like that

[chrome beacon]

Only store what you need

[soft hound]

So wait, after making a custom event , whenever I want it to be called I just use Bukkit.getPluginManager().callEvent(event_here); ?

[chrome beacon]

Yeah

[flint coyote]

Is it always the case that Listeners that listen to events that have extended Events catch the extended Events, too?
I just noticed that's a thing when I got a EntityTargetLivingEntityEvent while listening to the EntityTargetEvent which broke my logic since I had a map that stored the EntityTargetEvent class and therefore did not find anything for the EntityTargetLivingEntityEvent class

Basically I have a central listener (inside an api) that has to delegate back to the registrator. Now I gotta find a solution for dealing with extended Events.
Just wanna know if that's consistent across all events

If someone got a solution I'd also take that but it's probably not that easy

[wet breach]

well, its not that they necessarily catch the extended events rather the extended events relies from the base one. If you cancel the base event, then the extended can't fire since its an extension of it and relied on that event to be fired in order to fire as well

its basically the reason why there is some generic ones you can't cancel

but there is still some though where you could

[flint coyote]

Hmm that makes things a lot harder

[wet breach]

not necessarily, you could listen for the upper most one and uncancel

but, this is why there is a general etiquette devs should be following in regards to events. Such as not only using the appropriate events they need but as well as using the appropriate priorities and cancelling if its necessary. I will admit a lot of the times it is easier to just cancel and let the server handle that lmao

[flint coyote]

Well I basically have someone who's using the api create a function like that

@Override
    public Map<Class<? extends Event>, EventPriority> getEventsToRegister() {
        return Map.of(EntityTargetEvent.class, EventPriority.NORMAL);
    }

And prepare another function for receiving the listed events.

@Override
    public void handleEvent(Event event, EventPriority priority) {
        if (event instanceof EntityTargetEvent e) {
            onEntityTarget(e);
        }
    }

I now need to figure out a way to delegate back to the handleEvent even when I receive an EntityTargetLivingEntityEvent instead of the (registered) EntityTargetEvent. My approach so far was the following map:
Map<Class<? extends Event>, Map<EventPriority, TreeSet<RegionEvent>>> eventListeners = new HashMap<>(); where RegionEvent would be all Events (not bukkit events) that listen to a specific Event with the given Priority

Now that I can't be sure that I receive the exact Class that was registered, how shall I store and delegate correctly? I don't wanna listen to all super classes as I will then have to listen to EntityEvent and PlayerEvent.

[echo basalt]

mhm that's icky

[flint coyote]

yeah so far I don't really have an idea

[wet breach]

this is where reflection comes in

you actually can check if it is the exact class or not

[flint coyote]

Well I also wanna delegate the child events if the usual listener would receive them obviously

But even with reflection I would not know how to do that

[wet breach]

but, I think the simple solution would be to just add some information to your paremeters for the constructors

you can always tell the handle event which it is specifically

[flint coyote]

Not really since I only have one executor that has to delegate:

Map<Class<? extends Event>, Map<EventPriority, TreeSet<RegionEvent>>> eventListeners = new HashMap<>();
// .....................
@AllArgsConstructor
    private class CustomExecutor implements EventExecutor {

        private final EventPriority priority;

        @Override
        public void execute(@NotNull Listener listener, @NotNull Event event) {
            Map<EventPriority, TreeSet<RegionEvent>> regionEventMap = eventListeners.get(event.getClass());
            if (regionEventMap == null) {
                return;
            }
            TreeSet<RegionEvent> events = regionEventMap.get(priority);
            if (events == null) {
                return;
            }
            events.forEach(regionEvent -> regionEvent.handleEvent(event, priority));
        }
    }

I mean I do have one executor per Priority but they receive all types of events for that priority. And then using the map they get delegated to the right places

[wet breach]

you could check the event if it has a living entity or not

if it doesn't it is the top most event

if it does, its the living entity event

[flint coyote]

That applies to this event. What about all the others?

[wet breach]

as I said most others generally have a generic event you can't listen to or cancel

[flint coyote]

Yeah I figured that out when I tried to go with
https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/player/PlayerBucketEvent.html
vs.
https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/player/PlayerBucketEmptyEvent.html

[wet breach]

those are the same as what I said

you could just check for specific thing being set or not

really the only difference between them

EntityTargetEvent fires regardless of the entity, EntityTargetLivingEntity just provides a more specific event based on that if the entity in question is a living one

but I don't see why it would make a difference which event you ultimately listened to on that because they both essentially contain the same information

[flint coyote]

I mean I can make an exception for that event and handle it explicitly instead of generic like I currently handle all events. The problem is that this is prone to breaking for other cases like this

[wet breach]

the bucket event is the same way

[flint coyote]

You can not listen to the PlayerBucketEvent directly though

However you can listen to the EntityTargetEvent - you just might get a specific one with LivingEntity

[wet breach]

you could always make a pr to change that

it could have been in error or not really thought about when it was added

that the generic event should have been abstract

and that there should have been 2 events under it

one for living entities and then another for all others

but unless that happens you are just going to have to actually look and see which events this issue applies to and make exception code for each

sucks, but there is really no other way if you really must know the specific event

[prime epoch]

is there a standard effecient way to know if a player has entered a claim? all the methods i can think of are really inefficient

[wet breach]

bounding box

[prime epoch]

i got the bounding boxes stored but im not sure how to know effeciently if a player has entered one. Ive tried to look for some resources but theyre doesnt seem to be much out there

[flint coyote]

Meh. I guess I'll have to do that.
Basically if you wanna listen to EntityTargetEvent you'll also listen to EntityTargetLivingEntityEvent

[wet breach]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/util/BoundingBox.html#contains(double,double,double)

[prime epoch]

the main idea is that i loop through every claim and check if the player is inside of it but i feel like that could be inneficient

[wet breach]

use player move event to check

and use a hashmap

[prime epoch]

this was my idea originally. alrigh thanks

[wet breach]

this is probably a sign your code is probably not structured appropriately

one of the downsides of programming 🙂

[prime epoch]

most likely its my first java and spigot project lmao

[wet breach]

this is why refactoring code is a thing lmao

[prime epoch]

ive pretty much restarted my project like 3 times but im fine with it. Learning innit

[wet breach]

well, before you worry about efficincy

first get it working

its far easier to work with and around something that is working, then just theory

[flint coyote]

How would he utilize a hashmap here?

[prime epoch]

Yeah true. Im just used to working with games differently

[wet breach]

to store the location object as a key to check fast

if there is a matching key, then the value should be the claim

[flint coyote]

Store each block of a bounding box??

[prime epoch]

I'm going to use a Hashset with my claims class which looks like this

public class Claim {

    private Location corner_1;
    private Location corner_2;
    private BoundingBox bounding_box;

    public Claim(int corner_1_x, int corner_1_z, int corner_2_x, int corner_2_z) {
        World world = Bukkit.getWorld("world");
        this.corner_1 = new Location(world, corner_1_x, 0, corner_1_z);
        this.corner_2 = new Location(world, corner_2_x, 0, corner_2_z);

        this.bounding_box = new BoundingBox(corner_1_x, world.getMinHeight(), corner_1_z, corner_2_x, world.getMaxHeight(), corner_2_z);
    }
}```

and i'll just loop through each of them and see if the player is colliding

[wet breach]

well could, best not do that, still a bit tired. I would have to think about it a bit for an ideal solution

its probably going to take a double hashmap or even a multimap

[flint coyote]

That's what I do in my regional event api (I was just talking about), too

[prime epoch]

One otimization method i thought of is storing the chunk ids that have a claim in them and just checking the ones that the player has loaded

[wet breach]

ah right you could go by chunks if you want

since you could use bitshifting to check the chunk a given location is in

you shift by 15

[young knoll]

Chunk are free spatial partitioning

Done by the game for you

[wet breach]

you have a valid chunk coord when its divisible by 16

[flint coyote]

Yeah you could only check regions that are in loaded chunks and use the chunkload/chunkunload event to update that list

[prime epoch]

ohh im starting to get you now

[prime epoch]

Thats a really good idea aswell

[wet breach]

is your project public?

[flint coyote]

whose?

[wet breach]

you know if you toss it on github and routinely update it with your progress you might get some people willing to make pr's and the sorts 😛

also makes it easier to show what you have too

when you are stuck like this

[flint coyote]

Are you talking to AyPle or to me? lol

[wet breach]

yes

[flint coyote]

I see!

[wet breach]

Its directed to AyPle

lol

[prime epoch]

I can make my git repo public if you want to look at it

[wet breach]

since they are new to programming as they said

[prime epoch]

nah im not new to programming

[flint coyote]

Makes sense, yes

[prime epoch]

just spigot

[wet breach]

oh, well still applies all the same

[wet breach]

I can't guarantee that I will or not, I do every once in a while make contributions to some projects regardless of their popularity and skills. I do like contributing to those who are of lesser skill because it helps show how something can be done differently

but also remember this though, just because you think it is inefficient or doesn't use the most efficient method, doesn't mean it really is inefficient. It could be efficient enough which is all that matters really until it really is an issue

[prime epoch]

Yeah just atm the server isn't that great so im trying to cut costs basically lol

[wet breach]

an example, looping through an array of 1k and using a hashmap of 1k keys. Obviously the hashmap would be faster but you would only notice this difference if you actually measured it in microseconds to see that.

but those microsecond differences don't matter because you wouldn't have a large enough server where microsecond optimizations really make a difference

[tepid grove]

i know basic java from a course i did and i really want to know how to develop plugins especially minigames, does anyone know a good tutorial for total spigot beggnners or a good way to learn?

i follow that

[remote swallow]

does eclipse not have a bytecode decompiler

[worldly ingot]

It does

[young knoll]

It’s a plugin

[worldly ingot]

No it has a decompiler built in too, but the plugin is definitely much better because you can switch between a few different decompilers

[young knoll]

Huh TIL

I always used enhanced class decompiler

[worldly ingot]

Yeah I use it as well

[ornate patio]

anyone know how i can use nms to get all the vanilla potion durations and amplifiers

[worldly ingot]

They recently added support for Quiltflower which is nice

[worldly ingot]

There is PotionType, but it doesn't (yet) support multiple potion effects like the turtle master potion

[remote swallow]

do you have a pr open for it

[young knoll]

It also doesn’t have the durations

[worldly ingot]

Nah, the deenumification improves it

[remote swallow]

and do you have a pr to change the creative category stuff

[worldly ingot]

Change it how? They don't exist on the server anymore

[remote swallow]

been as some stuff is now in 2 categories

[remote swallow]

oh lol

[flint coyote]

The creative menu is entirely clientside right? No scrollable custom inventories

[worldly ingot]

I think honestly the fact that it existed on the server to begin with was an oversight

[young knoll]

Tbf I’m surprised they did before

[young knoll]

Ye

[remote swallow]

i would fookin love scrollable invs

rip scott tom

[young knoll]

Bedrock has fancy GUIs

[flint coyote]

Mojang knows very well we utilize inventories as GUIs and yet still they decided to not give us scollable inventories on the serverside

[young knoll]

I demand parity

mojang knows we need a better category of menus and yet doesn't create one...
