[wet breach]

odd your keyboard doesn't haven't a tilde though

[plain helm]

European keyboards don't have it

or at least Italian ones don't

idk if they're different in other EU nations

[wet breach]

do you have an alt gr key?

[plain helm]

yes

[wet breach]

then you have easy access to the tilde and backtick keys 🙂

[plain helm]

alt gr gives me access to the €

and

[wet breach]

alt gr + 7

gives you back tick

[plain helm]

nope

doesn't do anything for me

[wet breach]

then do this

alt gr + 7 and then hit 0

[vocal cloud]

this is easier than alt 96

[wet breach]

about to tell you

on some layouts

alt codes you know about sometimes don't work

[plain helm]

guys i'll just get it from the file it's not a problem

ty anyways

[vocal cloud]

Add a Cortana voice command for it 🤡

[wet breach]

oh I foudn it

its alt gr + ù

I was looking at the wrong layout from MS

https://docs.microsoft.com/en-us/globalization/keyboards/kbdit142

[plain helm]

doesn't work for me, idk what's wrong lmao

thanks for the help though

[wet breach]

well accordingly

for you its alt code 60

as well

weird your laptop keyboard isn't following the typical layout though

wonder if it requires the function key to be used too

[plain helm]

nope i tried it as well

[wet breach]

lol

[quiet ice]

Which Euro Keyboard are you using?

[plain helm]

fn key lights up with red the keys i can use with fn

[plain helm]

Italian, but appaently doesn't follow standard Italian keyboard layouts

[quiet ice]

If you have the accent grave (If that is the accent I think it is) you need to Press it twice in Order to get two backticks

That File will Take forever to Download with 16 kbits/s

There is a reason I often shoot very much in the dark

And the download failed. I cease to understand how https is so unreliable

Like, FTP is so much faster and reliable (If you increase the timeout)

[wet breach]

lol

technically could increase the timeout for https

in firefox for example
network.http.keep-alive.timeout 115 is the default you could increase it

same with websockets

chrome probably has similar setting somewhere

but I don't know it since that isn't my go to browser

[tender shard]

am I the only one who ALWAYS has problems wit jitpack?

[wet breach]

I sometimes have issues with it

especially its caching thing

so I stopped using it

[rough drift]

what do you need to know about it?

[tender shard]

when you remove some unused imports and now you have to recommit 20% of the whole codebase lol

[glossy venture]

Class100.java

tf

[tender shard]

public class Class100 {

[glossy venture]

bruh

[tender shard]

I didn't like it having 99 classes

I wanted it to be 100

[glossy venture]

bruh

[smoky oak]

thanks imma do that

[quasi flint]

no u dont

[smoky oak]

open source lol

watch me

[quasi flint]

[tender shard]

I also recommend this https://github.com/Jaimss/terrible-plugin

[granite owl]

does this already exist in the standard libs?

public class Pair<A, B> 
{
    public A first;
    public B second;

    public Pair(A first, B second)
    {
        super();
        this.first = first;
        this.second = second;
    }
}

seems abit silly to declare a pair

also can the plugin somehow detect this line from its plugin.yml ```yml
api-version: 1.18

(to auto disable itself if versions dont match cause i use nms methods)

[tender shard]

sometimes it's very handy

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/plugin/PluginDescriptionFile.html#getAPIVersion() this exists

but to detect the NMS version, you need a bit reflection

I always do sth like this:

        if(nms) {
            final String packageName = JeffLib.class.getPackage().getName();
            final String internalsName = Bukkit.getServer().getClass().getPackage().getName().split("\\.")[3];
            try {
                //abstractNmsHandler = (AbstractNMSHandler) Class.forName(packageName + ".internal.nms." + internalsName + ".NMSHandler").newInstance();
                abstractNmsHandler = (AbstractNMSHandler) Class.forName(packageName + ".internal.nms." + internalsName + ".NMSHandler").getDeclaredConstructor().newInstance();
            } catch (final ClassNotFoundException | InstantiationException | IllegalAccessException | ClassCastException | NoSuchMethodException | InvocationTargetException exception) {
                plugin.getLogger().warning("The included JeffLib version (" + version + ") does not fully support the Minecraft version you are currently running: " + internalsName);
                exception.printStackTrace();
            }
        }

now "internalsName" is e.g. "v1_18_R2"

[granite owl]

hehe teye

cause i wanna avoid nms as much as possible

but since i plan a plugin for custom entities that injects its entities into the server

version mismatch could crash things

[tender shard]

what MC version are you on?

because if it's 1.17+ you HAVE to use the remapped jar for custom entities, otherwise it won't compile. But you should be using remapped anyway 😛

[granite owl]

1.18

and yes

ive noticed that

using it

[chrome beacon]

Remapped makes things much easier

[granite owl]

how so

it just complicated it for me

to import it

because i didnt know of the change

otherwise it seems pmuch similar to me

[chrome beacon]

How is a(), b(), c() simillar to coolMethodName(). All you really need to do is copy paste remap config in to your pom and you're good to go

Takes less than 5min

[granite owl]

so it took the vanilla obfuscating out

[tender shard]

with remapped, you can basically code sth once for 1.17.1, then compile exactly the same code against 1.18.2 mappings and it'll still work in 99% of cases

[granite owl]

hm

[smoky oak]

what's the regex for 'all non numeral characters' ?

[tender shard]

\d

if you only mean [0-9] at least

do you also want to allow floats / doubles?

[smoky oak]

no

i want to extract the number from a string

wait

\d does numbers

not not numbers

[tender shard]

ooh

\D

[smoky oak]

huh

ok then

[quasi walrus]

hello id like some help with getting 1.18.2 plugin development started [idk if im doing it right]

i downloaded the buildtools.jar that i made a bat

java -jar BuildTools.jar --rev 1.18.2 now im just waiting is this right?

[tender shard]

it depends. do you need to access NMS code?

I once wrote a tiny tutorial on how to get started with IntelliJ + maven + spigot-api: https://blog.jeff-media.com/how-to-create-your-first-minecraft-plugin-using-the-spigot-api-and-maven/

[quasi walrus]

um idk what nms code means, im just familiar with how 1.16.5 does it all i really need is the jar that you add to dependences

[tender shard]

then you don't need to worry about NMS

but anyway, I highly suggest you to use maven. it might seem a bit complicated at first, but it actually makes everything much easier

my blog post explains everything you need to do to get a working maven setup

[quasi walrus]

oh

[smoky oak]

is this normal for /data get @p ?

[tender shard]

yes

[tender shard]

the green part you see is the discovered recipes etc, the second half is mainly their inventory

[smoky oak]

ah makes sense

does that also contain the creative saved items?

[tender shard]

no, the creative inventory is 100% client sided

[quasi walrus]

um could i still get help with getting the jar file for dependences the build tools stopped running and the spigot-1.18.2.jar doesnt work

[tender shard]

oh wait, it actually does include it

[smoky oak]

huh

[tender shard]

but you can't really rely on it

[smoky oak]

pdc contains book pages

[tender shard]

yes sure

well, not really PDC. the book pages are inside an NBT tag

but PDC basically IS NBT

[smoky oak]

ah i see

[tender shard]

it's simply an interface to access it using spigot API instead of NMS

[smoky oak]

imma assume getinventory interfaces with PDC then

[tender shard]

wdym?

[smoky oak]

well if the inventory is stored in the PDC

[tender shard]

no, it's not

PDC is stored inside an NBT tag called "BukkitValues"

[smoky oak]

ah note taken

[tender shard]

check out the 6lth line from the bottom

everything inside BukkitValues is the data you get from player.getPersistentDataContainer()

[quasi walrus]

is there no way to make 1.18.2 plugins without maven?

[smoky oak]

gradle

[quasi walrus]

um

[quasi flint]

There ist a was without

But Just dont

[quasi walrus]

eh

all i need is the dependency file or at least how to get it q~q

[smoky oak]

thats just the spigot api

[cold field]

Heya guys quick question. Do you know any lib that helps me build JSON messages?

[chrome beacon]

Adventure

[quasi walrus]

how would I get it?

[cold field]

Isn't that a paper thing?

[chrome beacon]

You can shade it in to your plugin if you want it

[cold field]

Uhm, ok great ty

[chrome beacon]

?bootstrap

[undone axle]

Bootstrap Jar
The main spigot-1.18.jar is now a bootstrap jar which contains all libraries. You cannot directly depend on this jar. You should depend on Spigot/Spigot-API/target/spigot-api-1.18-R0.1-SNAPSHOT-shaded.jar, or the entire contents of the bundler directory from your server, or use a dependency manager such as Maven or Gradle to handle this automatically.

Please read the release notes for further information: https://www.spigotmc.org/threads/9-years-of-spigotmc-spigot-bungeecord-1-18-1-18-1-release.534760/#post-4305163

[quasi walrus]

oh thanks

[eternal needle]

if i need to transleate a list with color codes in config do i need to have it a spesial place?

[tardy delta]

ChatColor.translateAlternateColors

On each element

[lean gull]

anyone know a good tutorial on world gen? i tried the one on the bukkit fandom but its old and outdated

[sterile token]

The spigot one

Search it liKe: "Spigotmc World gen"

[lean gull]

can you send me a link

[quaint mantle]

Hello world

[sage dragon]

Cancelling EntityChangeBlockEvent seems to remove Falling Blocks, is that correct behaviour?

[glossy venture]

you mean when it hits the ground?

because then, yes

[grim ice]

i need a lib idea

[smoky oak]

how can i find all entities in a radius around a location? Is my only option to spawn in an invisible entity and use the getNear function (alternative to iterating through every entity in the world and checking their location)?

update: get all entities in a chunk and iterate through those

[crimson terrace]

World has a getNearbyEntities() method

that being said, that method iterates through all entities in that world to see which ones are close enough to the location specified. You wont get around that I believe

[grim ice]

yeah i was gonna say that

[smoky oak]

can i do a for (a : aset; b : bset) in some way/form? I have two sets i need to iterate through and perform an operation on each of the entry pairs of the sets (they have guaranteed the same length)

also does null count as duplicate entry in a set?

[grim ice]

nested loo[p

loop

for each a in aset, loop through b in b set

or make a wrapper class

[smoky oak]

ah not what i meant

i need to perform an operation on every pair in the set per index so to speak

also i just realized i need to use ArrayList

[glossy venture]

you can get 2 iterators

for (a : b) is just syntatic sugar

@smoky oak

Iterator<...> asetIter = aset.iterator();
Iterator<...> bsetIter = bset.iterator();
while (asetIter.hasNext() && bsetIter.hasNext()) {
  var aItem = asetIter.next();
  var bItem = bsetIter.next();
} 
``` something like this

fucking ugly but it works

idk for sure im doing the order right

one sec

[smoky oak]

isnt that the complicated equivalent of java for(int i = aset.length()){ var aI = aset.get(i); var bI = bset.get(i); }

where's the difference?

[glossy venture]

Set<...> isnt ordered it doesnt have a get(int) method right

[smoky oak]

well i realized i could get duplicate entries

so i corrected myself

to ArrayList

[glossy venture]

oh

bruh

yeah then just do that

[dusty herald]

Sets can't get duplicate entries though?

[smoky oak]

correct

im trying to get all entities in specific bounding boxes

[dusty herald]

oh ok

[smoky oak]

which might be in the same chunk

[dusty herald]

I thought u meant that sets can

[smoky oak]

as such a set for the location.getChunk.getEntities() might have duplicates

also does a location point to the corner of a block with the lowest coords or to the middle of it?

[glossy venture]

block location is an int i think

[smoky oak]

which does not answer the question

[brave sparrow]

How would this have duplicates

[smoky oak]

box = new BoundingBox();
box.resize(l.getX()-.5,l.getY()+.5,l.getZ()-.5,l.getX()+.5,l.getY()+1.5,l.getZ()+.5);

reason i ask is bc im unsure if i have to use 1.0 instead of 0.5 here

[brave sparrow]

You add 0.5 to each to get the middle

[smoky oak]

ah

so it's 1

thanks

[smoky oak]

List of locations around which to check, list of Entity[] in the chunk the location is in

if two in same chunk

dupe

[brave sparrow]

Ah, so you’re checking chunks multiple times and combining them into one aggregate collection

I see

[smoky oak]

it's the only solution i found so far

        List<BoundingBox> pset = new ArrayList<>();
        List<Entity[]> eset = new ArrayList<>();
        BoundingBox box;
        for(Block b : blockList){
            if(b.getType() == Material.WAXED_COPPER_BLOCK){
                l = b.getLocation();
                box = new BoundingBox();
                box.resize(l.getX(),l.getY()+1,l.getZ(),l.getX()+1,l.getY()+2,l.getZ()+1);
                pset.add(box);
                eset.add(l.getChunk().getEntities());
            }
        }

[brave sparrow]

Yeah that’s not a bad solution, it just wasn’t clear from your original explanation that two could occur in the same chunk at once

Whoa whoa whoa

Why are you adding arrays to it

Why not just have a List<Entity> and stick them all in that

[smoky oak]

bc Chunk::getEntities() returns Entity[]

[brave sparrow]

So?

You can iterate through that array

[smoky oak]

might be a solution

[brave sparrow]

If all you’re going to do with that array later is iterate through it you might as well

[smoky oak]

this looks disgusting but i guess it works

      Set<ItemStack> r_set = new HashSet<>();
        for(BoundingBox b : bset){
            for(Entity e : eset){
                if(e instanceof ItemStack && b.contains(e.getLocation().toVector())){
                    r_set.add((ItemStack) e);
                }
            }
        }

        return r_set.toArray(new ItemStack[0]);```

[grim ice]

Bro

an entity cant exist twice

normally

looks disgusting because of how you did it

[smoky oak]

no but the array returned from Chunk::getEntities() can be the same if it's called in the same chunk twice

[grim ice]

what is rset

[smoky oak]

set of ItemStack[] array to be returned before conversion

done that way to make sure i dont get an arrayIndexOutOfBoundsException

[grim ice]

what does it do

[smoky oak]

store all entities found in the defined bounding boxes

[grim ice]

        Set<ItemStack> entitiesFound = new HashSet<>();

        for(BoundingBox boundingBox : boundingBoxes){

            for(Entity entityEntry : entities){

                if(entityEntry instanceof ItemStack && boundingBox.contains(entityEntry.getLocation().toVector()))

                entitiesFound.add((ItemStack) entityEntry);

            }
        }

        return entitiesFound.toArray(new ItemStack[0]);```

[brave sparrow]

Wait wait wait

First of all

Entities can’t be item stacks

[grim ice]

Yep

[brave sparrow]

They’re Items

Second of all

[grim ice]

not my code

just fixed naming for it

Lo

now it looks much better

[glossy venture]

why convert it to an array

[brave sparrow]

Why do you care if they’re in the chunks twice if the end result is a set

That will eliminate duplicates anyway

[glossy venture]

integers cant be half, so i think it would be in the corner

[grim ice]

the loop will never run anyways

Entity is never an itemstack

[smoky oak]

actually due to the fact the bounding boxes cant overlap, the duplicates would have in both iterations of the code only been added once to the return set

also for some reason it doesnt throw an error

yet

[brave sparrow]

There’s no error because you’re checking for entity instanceof ItemStack

Which will always return false

So it never goes any further

[smoky oak]

ah

[grim ice]

moterius

do u know java

[smoky oak]

good enough in most cases

doesnt mean i know the bukkit api from the top of my head

[grim ice]

ic

[smoky oak]

if(e instanceof Item && b.contains(e.getLocation().toVector())){
  r_set.add(((Item) e).getItemStack());```, then?

yep

[brave sparrow]

why are you doing b.contains

if they're in the collection of entities they were in a bounding box

you don't need to check it again

right?

[smoky oak]

it's not boundingBox.getEntities but location.getEntities

the b.contains is to make sure the entities are inside the bounding box and not just in the same chunk as it

[brave sparrow]

oh you're not using the bounding box to filter the entities before this?

[smoky oak]

im doing the filter here

[brave sparrow]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/World.html#getNearbyEntities(org.bukkit.util.BoundingBox,java.util.function.Predicate)

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/World.html#getNearbyEntities(org.bukkit.util.BoundingBox)

use those

[smoky oak]

I've been specifically told not to use them because they iterate through all entities in that world

also since when the fuck are entities considered dupilcates when the only difference betwen is the location

[brave sparrow]

unless you're envisioning having 100000000 entities in the world or something this shouldn't be a sizeable difference

[fading lake]

wait when did spigot create a util class for bounding boxes?

[brave sparrow]

¯_(ツ)_/¯

[fading lake]

seems pog

[smoky oak]

well then imma replace that set with a list

[brave sparrow]

@smoky oak i just ran the numbers with a quick test program

if your world has

500000 entities currently loaded in

which btw would freeze your server anyway

the time to check them all against 25 bounding boxes is about 234 milliseconds

[warm light]

How to check if Inventory is not a Chest Inventory?

[smoky oak]

I'm going to take a look at it then

[warm light]

from InventoryCloseEvent

[brave sparrow]

plus you can use the Predicate one to only return Items

[smoky oak]

my method either returns duplicates or, when using a list instead of a set, removes some entities

[warm light]

nvm got it

I have created an inv using this.
what is the inv type?

[river oracle]

Whatever you set it to though its a chest ui if no type is not specified

[warm light]

ok. thanks

[desert musk]

i wanna make a plugin now where you can make potions recharge their use either through doing damage to mobs or gaining xp

is that feasible?

[desert musk]

much like the mending enchantment ig

[cobalt tinsel]

@EventHandler(ignoreCancelled = true)
public void onPlayerMove(PlayerMoveEvent event) {
Profile profile = Profile.getByUuid(event.getPlayer().getUniqueId());
Match match = profile.getMatch();

    if (event.getPlayer().getLocation().getBlock().getType() == Material.WATER) {
        if(match.getKit().getName().equalsIgnoreCase("Sumo")) {
            event.getPlayer().setHealth(0);
            event.getPlayer().spigot().respawn();
        }
    }
}

why is that not working

[grim ice]

so true how is it not working

i wonder

[cobalt tinsel]

if(match.getKit().getName().equalsIgnoreCase("Sumo")) {

this line is working

i tested

[eternal oxide]

You should test event.getTo() not the players location

[cobalt tinsel]

ok

hmm

if (event.getTo().getBlock().getType() == Material.WATER) {
if(match.getKit().getName().equalsIgnoreCase("Sumo")) {
event.getPlayer().setHealth(0);
event.getPlayer().spigot().respawn();
}
}
}

like that?

[eternal oxide]

yes, that will trigger when you step into water

[cobalt tinsel]

kk

[grim ice]

also

start with less expensive checks

check the block before that

[eternal oxide]

^

[lusty raft]

Might want to check for the water before you get the profile aswell

nvm

beat me to it

[eternal oxide]

yes, always early exit in teh move event if you can

[cobalt tinsel]

well didn't worked

[tardy delta]

Don't People know that && exists?

Of early returns

[cobalt tinsel]

i tested it but didn't worked :C

[tardy delta]

That's not because of that lol

[lusty raft]

..

[prisma needle]

Getting data from Offline Players

[safe edge]

C:\Program Files\Java\jdk1.8.0_321\bin\java.exe -jar BuildTools.jar --rev 1.8.3 What should I add to run java 8 ?

[desert musk]

can you completely make your own enchantments using only a plugin?

[ivory sleet]

Basically yeah

[desert musk]

great

is there a player property or function that allows you to make them “wet” all the time

[ivory sleet]

Altho you’d have to in principle add custom lore for displayable visibility in regards to the client

wym by wet?

[desert musk]

specifically so they don’t get burnt or have riptide effects

(so they can fly during the day basically)

((with a trident))

weird sounding question but idk

[lusty raft]

You can do all of that

[desert musk]

pog

im having a difficult time trying to figure out where to split up my plugin features

[lusty raft]

you can also use my plugin eliteenchantments and code your own effect

[desert musk]

like i could either make a large conglomerate plugin that incorporates all the features i need for my server

or i could split it up tediously into multiple plugins

[lusty raft]

It's best to make a core plugin with small features and then separate plugins for large features ie. enchants, events etc.

[desert musk]

cool

[lusty raft]

That way if something breaks you don't need to disable your whole plugin with all the features only the plugin that is broken

[desert musk]

right

makes sense

[ivory sleet]

I mean in spigot it doesn’t impact that much how you like to isolate features into jars tho

[desert musk]

yeah but i just want to be neat basically

also a lot of the features im making i don’t see anywhere else and i might wanna publicize them

but i’m not gonna do that for just a very niche plugin that incorporates all these weird features into one package

[ivory sleet]

Well in enterprise or more professional environments you might wanna extract modules that may change for fragile reasons into separate ones/jars such that the entire system doesn’t have to recompile everytime a binary incompatibility change takes place

[desert musk]

yeah

i mean i’ve literally never made a plugin before so i don’t know what it’s like updating through minecraft’s changes

[ivory sleet]

Yeah, got a lot of fun ahead of you then

[desert musk]

lol

i should look into mcmmo

although what i’ve seen of it i don’t really like all that much

[ivory sleet]

Is mcmmo’s source good?

[desert musk]

but it might be fun to have

[lusty raft]

It's not too bad if you are only working on plugins for your own server

[desert musk]

mhm

[lusty raft]

Ngl if you want to look at some good code to learn from... hate to say it since he is ugly but Auxilor plugins code

[ivory sleet]

But yeah since you did wanna code enchants even looking at sth like splodgeboxs or auxilors enchant plugin could enhance your understandings possibly

[desert musk]

lmfao

[desert musk]

cool

[ivory sleet]

Auxilors code is probably good enough

[lusty raft]

My code isn't public but hopefully soon will be 🤞

[ivory sleet]

Last time I looked some of the design choices in his lib was questionable although nothing you’d have to worry about pricedown

Ah

[desert musk]

coming from c++ to java is there anything i should really know, like am i allowed to just jump from cpp to java as a cheat or should i just learn the whole lang

[ivory sleet]

Well

No manual memory management basically

[desert musk]

rip

but ig that’s fine

[lusty raft]

c++ is pretty similar but there are a lot of differences in practises etc.
Shouldn't be too hard to learn Java tho for you

[ivory sleet]

Or well you still have it with Unsafe and VarHandle to some extent

But like the gc will handle memory for you

[desert musk]

right

[ivory sleet]

Like it’s genuinely hard to achieve a memory leak if you think enough whilst coding

[desert musk]

lol

i’ll try to learn the language in general though ig because ik learning a language for the express purpose of a single project rarely goes well

like it’s better to familiarize yourself with the whole environment

it’s like ppl that don’t know c++ that ask to learn how to make game hacks from me

[ivory sleet]

Idk

Some people do fairly well when working on sth whilst learning the language

Others don’t

[desert musk]

mhm

i’m just hasted by how the server is currently up and running and i have so many ideas but can’t apply them all in time

[ivory sleet]

But if you came far in cpp (like even multithreading, templates and object orientation) Java will most likely be a piece of cake for you

[desert musk]

ok good

[desert musk]

it’s just annoying having to detour so far from brainstorming new gameplay ideas

takes so long to implement stuff

currently everythings running in the server using only datapacks lmfao

[ivory sleet]

Hehe yeah well I tend to use libraries

[desert musk]

and it works but some stuff is missing

[desert musk]

what general libs do you recommend

[ivory sleet]

So usually doesn’t take that long for me, altho as they say there are no zero cost abstractions

In the start none

[desert musk]

mm

ok

[ivory sleet]

But have a look at GitHub repositories such as awesome-java and awesome-minecraft

[desert musk]

interesting

i will

[ivory sleet]

Alright good luck (>:

[desert musk]

yes

[tender shard]

I hate noteblockapi

[vocal cloud]

Header files are optional

[manic delta]

File file = new File("mySchem.schematic");
Vector pos1 = new Vector(loc1.getX(),loc1.getY(),loc1.getZ());
Vector pos2 = new Vector(loc2.getX(),loc2.getY(),loc2.getZ());
World world = new BukkitWorld(loc1.getWorld());
CuboidRegion region = new CuboidRegion(world, pos1, pos2);

can someone help me?, I want to save a world edit selection to a schematic file, this is because I want to save copies of certain places to be able to paste them later (It's for a minigame) I've been looking for days how to do it and the ways I found don't work and in the world edit discord do not support 1.8, maybe some of you know

Im using world edit api and 1.8 version

[chrome beacon]

Time to update 😉

[crude loom]

Hi, I'm trying to detect when an item is being burnt by lava, here is my code:

@EventHandler
    public void onEntityDamage(EntityDamageEvent event){
        Entity entity = event.getEntity();
        if(entity instanceof Item && event.getCause() == EntityDamageEvent.DamageCause.LAVA)
        {
            Bukkit.broadcastMessage("burnt");
        }
    }

But because the item is being damaged twice this event fires twice, any idea on how to fix this?

[chrome beacon]

If you only want it to fire once save the UUID to a Set and don't do anything if the Set contains the UUID

Alternativly only do stuff if it's in the Set depending on what you want

[crude loom]

Oh that's smart

I'll do that, thanks! :D

If an item takes damage once, it's impossible for it to survive right?

[stiff zinc]

Well yea

[crude loom]

And if multiple items will get burnt at the same time will it add it to the same list? Or is it like every user has it's own list

Or every time the event runs or whatever

[stiff zinc]

That would depend on what you are actually trying to do

[crude loom]

If I just add the id of the item to a list every time it's being damaged with the event

Then another item is being damaged

Will it be the same list? or does it create a new one in the memory?

Also if I check a value in the config every time this event fires
Will this be intensive for the server?

[granite owl]

does someone have exp with deserializing inventories from player dats?

to view the inventories of offline players

[echo sentinel]

When I have InventoryClickEvent and action is HOTBAR_SWAP, how can I get two items that are swapped?

[stiff zinc]

@crude loom use EntityCombustEvent

For when the item burns

No need for a list

[crude loom]

Will this work on both lava and fire?

[echo sentinel]

for example when i have stick on slot 1 inventory and on slot 2 I have diamond, when I hover over stick and press 2 on keyboard items get swapped, but when I use e.getCursor() + "\n" + e.getCurrentItem() it returns ItemStack{AIR x 0} ItemStack{STICK x 1}

so my question is how can I get both items that are swapped

[grim ice]

@granite owl when a player logs out

store his inventory

ez

however you like it

[echo sentinel]

Will someone help me?

[viral crag]

you can try inventoryview, however, what you want is mostly clientside

[echo sentinel]

What can I do with inventoryView

[sage dragon]

Is getServerInfo case sensitive?

[ivory sleet]

iirc yes

[wispy plume]

How can I open a book for player in 1.12.2? got a solution

[granite owl]

i was having the same idea but i feel like having additional files for one and the same thing does make things more fragile

like ofc i can serialize it from the object in memory

but i was thinking of accessing the "real" inventory directly from the players file

and write to that

[viral crag]

you can also use something like prism or coreprotect - all that data would be in the database

[granite owl]

prism

Hello! How I can create an empty ConfigurationSection object?
Simply create a "yamlconfiguration" object, or what I need to do?

[ivory sleet]

ConfigurationSection::createSection exists

[agile sand]

oh.
really? that was too easy... thx!

[ivory sleet]

well

you do have some other options

but I'd stick with createSection

for instance you could pass a new MemorySection() or simply a new MemoryConfiguration()

[lean gull]

anyone got a good tutorial for world gen? i tried the one on the bukkit fandom but its outdated

[crude loom]

Should Player.getInventory().remove() remove 1 item from a stack if it's amount is more than 1? or should it just remove the whole stack regardless of the amount

[tall dragon]

it will remove all matching stacks

[crude loom]

I see, how do I remove 1 item from the stack then?

[tall dragon]

loop through the inv till u find the matching item

and decrement the amount

[crude loom]

I will try that, thanks :D

Oh, setting the amount to 0 is the same as removing the item, I see
Anyways, this works now thanks for the help :D

[tall dragon]

👍

[granite owl]

is LootGenerateEvent the callback that fires when opening villager/dungeon etc chests?

[grim ice]

BROOO

WTF

NO

use removeItem

[smoky oak]

uuuuuuuuuuummmmmmmmm........
does anyone know why in the world it seems impossible for bukkit to give me two item instances as long as they're duplicates of each other?
I set up a scan that tells me the items over a block, but this scan does NOT work once i throw down items with the same type & stack size?????
code is basically this (with a check if it's in a bounding box):

Collection<ItemStack> ent_col = new HashSet<>();
for(Entity e : allEntitiesInWorld){
    if(e instanceof Item)
      ent_col.add(((Item) e).getItemStack());
}
print(toMaterialString(ent_col));

And the following happens:
[1x Amethyst block] -> AMETHYST_BLOCK
[1x Amethyst block][1x Copper block] -> AMETHYST_BLOCK+COPPER_BLOCK
[1x Amethyst block][2x Amethyst block] -> AMETHYST_BLOCK+AMETHYST_BLOCK
and here's the dumb part:
[1x Amethyst block][1x Amethyst block] -> AMETHYST_BLOCK

the fuck???

[hasty prawn]

HashSet requires unique elements.

[smoky oak]

dont items have location?

[ivory sleet]

Item does, but ItemStack nope

[smoky oak]

urgh

[hasty prawn]

^

[lean gull]

anyone?

[tall dragon]

thats pretty restrictive imo

how would you remove 1 item from a stack

that method removes as much as it can find of the same type & amount

[tardy delta]

oh is the signature of the Set#add method add(Object) instead of add(E) to make you able to add objects which extend E but arent cast already?

[viral crag]

https://www.spigotmc.org/threads/world-generation-how-to.230970/

[ivory sleet]

for Set its add(E) tho for map its put(K,Object) iirc

[tardy delta]

wait

it was with map

:c

not all people were drunk when they wrote this

[lean gull]

this is a thread, not a tutorial

[tardy delta]

but for example map:
V remove(Object key);
boolean containsKey(Object key);

[ivory sleet]

yes

[tardy delta]

to avoid casting?

[viral crag]

thats nice, it addresses what you think your problems is with the tutorial are

[ivory sleet]

nah

mainly due to backwards compat

[tardy delta]

oh i thought the person who wrote this drank to much

[lean gull]

even if i can get the tree populator to work, idk how to make it so it creates a new world and idk how to make it customizable

[viral crag]

then perhaps you shouldnt be doing it?

[lean gull]

not knowing something = shouldnt do it?

[viral crag]

maybe, try getting one of those 3 things to work first?

[lean gull]

it won't help

[viral crag]

probably not

making bread so you have sliced bread to make a sandwich is never a good idea

[manic delta]

i dont like new versions pvp

[hasty prawn]

OCM

[tardy delta]

then go to the shame corner

its right there

[viral crag]

6 million pvp plugins and none of them work 😆

[manic delta]

meh

[hybrid spoke]

i can pvp without a plugin

[tardy delta]

i cant pvp

[manic delta]

i think i will try cloning the world

[tardy delta]

sorry god

[manic delta]

bcs no one can help

💀

[hybrid spoke]

dont worry i will train you

[tardy delta]

good

[lean gull]

anyone?

[viral crag]

"no one can help" or no one sees it as a good use of thier time?

[manic delta]

both

[viral crag]

i sure someone might if you paid them

[manic delta]

meh

i just will clone the world

it's an empty world anyway

[viral crag]

most of those are 1.12-ish no?

yeah - I generally only see them when someone runs curseforge

[ivory sleet]

afaik there aren't any good ones

like actually good ones

[viral crag]

classes i'd think you could handle via luckperms tracks, races would be more difficult if it goes beyond factions

pretty large design undertaking and probably why no good ones are out there or maintained at current release

put no sarcasm in those last posts

hahaha werent you all about yourself a short while ago?

[hasty prawn]

Well that's basically impossible

[viral crag]

write down a list, put it on a map and include space for forks/features to ignore until your done your main list

you will never satisfy everyone and to go out of your way to support legacy items is not worth it

[hasty prawn]

Well you've already failed to make everyone satisfied

[viral crag]

then you have special cases to put in your feature requests to ignore until the core is done

you will eventually come to the conclusion that some requests are stupid or impossible

one hopes so, however you still want your core to be stable and maintainable

[ivory sleet]

I'd say most important thing with big projects is to get stuff done, doesn't have to be perfect the first time but make sure you progress, else you'll get rather demotivated hastily

[viral crag]

measurable stuff done!

[ivory sleet]

From personal experience I've worked with talented people, but (some of them) pay too much attention to insignificant details like "Oh you use singleton here, must refactor :))))", which of course makes sense but it slows the rest of the team down enormously, well Idk if you're working with some1 now but you get the gist of it I hope

(Well this doesnt go without saying that paying attention to details isn't always bad, but yeah, find a balance :^))

[viral crag]

if you know how to use them, gantt charts are valuable for visualizing that type of issue

[rich inlet]

Hey,
my PlayerInteractEvent somehow gets fired twice, even after I checked for event.getHand() == EquipmentSlot.HAND. This is my code:

event.setCancelled(true); if (item == null) return; if(event.getHand() == null) return; if (event.getHand().equals(EquipmentSlot.HAND)) { if (event.getAction() == Action.RIGHT_CLICK_AIR || event.getAction() == Action.RIGHT_CLICK_BLOCK) { int itemSlot = player.getInventory().getHeldItemSlot(); if (itemSlot == 0) { //code } } }

[viral crag]

you have two hands ...

[rich inlet]

Yes, but the offhand is EquipmentSlot.OFF_HAND

[last sleet]

If I wanted to add, for example, a "COMMON" or "RARE" or "EPIC", etc. tag into an item when crafted (so adding that tag when crafting vanilla items), would I need to override all vanilla crafts and replace them with my own "custom" recipe, just to add those tags, or is there a better way?

[last sleet]

Like an event or something that fires when I craft, and then, with the help of a HashMap, I can just come in and set the tag to the item

[viral crag]

Represents an event that is called when a player interacts with an object or air, potentially fired once for each hand. The hand can be determined using getHand().

you know what hand you want, are you cancelling the other one?

[last sleet]

Thanks!

[rich inlet]

            event.setCancelled(true);
            if (item == null) return;
            if(event.getHand() == null) return;
            if (event.getHand().equals(EquipmentSlot.HAND)) {
                if (event.getAction() == Action.RIGHT_CLICK_AIR || event.getAction() == Action.RIGHT_CLICK_BLOCK) {
                    int itemSlot = player.getInventory().getHeldItemSlot();
                    if (itemSlot == 0) {
                    // Code
                    }
                }
            }

[rich inlet]

As you can see in the code block, I checked for event.getHand().equals(EquipmentSlot.HAND)

[tardy delta]

no need for equals

[rich inlet]

Okay, but still calls two times. But only, if I look directly down. When looking at another block or in the air, its fine

[tardy delta]

interact event?

[rich inlet]

Yes

[tardy delta]

for each hand

[ivory sleet]

make sure you didnt register it twice btw

[rich inlet]

I didnt, I already checked

And there is always a golden pressure plate beneath me, when this event is called. Maybe this helps

I think it has to do with hat, because it always calls twice when I look at the pressureplate. When I look at the pixel on the edge of the pressure plate, where just the block beneath is, then its fine

[viral crag]

I would say do a quick console output and check, not sure what you have would cancel both events. As EquipmentSlot[] is an array it might still be valid if you dont remove the HAND enum

[smoky oak]

try doing a if(Hand == EquipmentSlot.MAIN_HAND)

something along those lines

wait

[rich inlet]

There is no MAIN_HAND, only HAND and OFF_HAND

[smoky oak]

yea i just realized

ah

do event.getHand() == EquipmentSlot.HAND instead of .equals

might be the issue

[rich inlet]

And as I said it works perfectly when looking on any block/air except when looking down on the pressure plate

[viral crag]

wait, on a pressureplate?

[rich inlet]

Yes

[smoky oak]

maybe the game triggers the event twice since its a redstone component?

[rich inlet]

Standing on a pressure plate is a playerinteractevent hmm

[viral crag]

so the hand interacts with the pressureplate and the pressure plate interacts with the hand

[rich inlet]

And is there a way to fix this?

[viral crag]

check if your on a pressure plate and suppress one. however before that make sure it doent happen on a regular block

it shouldnt

[rich inlet]

what do you mean by supress one?

[viral crag]

check if you are interacting with a pressure plate and choose which one to ignore and which one to handle it

[rich inlet]

So i can basically check if the Action is PHYSICAL?

[viral crag]

mmm i think you will also have the same issue with buttons and sculk sensors

[rich inlet]

ANd if so, return

[smoky oak]

anyone else here hating regex too?

[viral crag]

yeah one of the action types might work

[rich inlet]

if(event.getAction() == Action.PHYSICAL) return; does not help

[viral crag]

you would want to do the opposite

PHYSICAL
Stepping onto or into a block (Ass-pressure) Examples: Jumping on soil Standing on pressure plate Triggering redstone ore Triggering tripwire

[rich inlet]

Well, my event should only trigger if it's not the Physical one, but the right clicking

[viral crag]

unless what you are doing is supposed to be on the pressure plate

[sinful hedge]

do you knows a Discord bot plugin that displays the status and player count of a Minecraft server in the sidebar?

[viral crag]

okay so you want not PHYSICAL

[rich inlet]

but I return at the end, so the next code doesnt get executed?

[sleek pond]

Yea your right

[viral crag]

your test above should return, I never trust it to do that though

[sleek pond]

Although I would do if action != Right hand refurn

[smoky oak]

why does this not work?

replaceFirst("~ /.*"+separator+"(.*)/","");```
it's supposed to cut off every slash in the file string but the string returns unmodified

[sleek pond]

?

[viral crag]

its a habit and code rule for certain types of programming, there should only ever be one return and always at the end.

[worn tundra]

How do you assign it

[smoky oak]

i read the file location in

[viral crag]

anyway, drop in a comment to make sure which event you are handling and responding to

[smoky oak]

imma try something else

[rich inlet]

It's all about the PlayerInteractEvent

[smoky oak]

aha

String name = s.getType().getName();
name = name.substring(name.lastIndexOf(separator+1),name.length()-4);```

no regex necessary

[viral crag]

yes, but check your conditions

[rich inlet]

I already checked them and have no clue, and I already sent them in here

if (event.getAction() != Action.RIGHT_CLICK_AIR && event.getAction() != Action.RIGHT_CLICK_BLOCK) return; also doesnt help

[viral crag]

are you firing in both conditions or just one?

[rich inlet]

Only when the hand is the main hand

[sharp bough]

i had a similar problem and dbuged it with https://pastecord.com/icelizacop.java

that works as expected

if that fires twice then you are registering the event twice

[grim ice]

give me lib ideas

[crude loom]

I don't really know the difference between the different sever types, like paper, bukkit and spigot so if I give someone a plugin I coded in spigot should it work no matter what his server type is or do I need to do something?

[brave sparrow]

But not for Java, there’s no reason not to trust a return statement in Java lol

[grim ice]

spigot plugins work in bukkit and paper, except if you use .spigot() functions i think

but paper will always work with spigot

[crude loom]

I see, is there a server type that wont work with my plugin?

[brave sparrow]

What if the extension is longer or shorter than 4

[viral crag]

depends if you share your code or not

[grim ice]

Spigot plugins are fine with paper servers
paper plugins are not fine with spigot servers

[grim ice]

what type

[smoky oak]

luckily i only have to deal with one type of extension atm

alternatively i use indexOf(".")

[brave sparrow]

What are you talking about? There’s nothing wrong with a return statement

[grim ice]

if its in paper it might not

[crude loom]

Is there more than paper,spigot and bukkit?

[smoky oak]

forge

[grim ice]

yeah but theyre uncommon

[viral crag]

randomly buried returns results in random issues - when someone else uses the code

[brave sparrow]

@crude loom a Bukkit plugin works for Bukkit, Spigot, Paper, whatever is downstream from Paper, etc. A spigot plugin is guaranteed to work for anything spigot or later, and may work for bukkit. And so on and so on and so on

[brave sparrow]

Sounds like your methods are too long. And the returns aren’t “random”, they’re specific exit conditions that should be documented

[crude loom]

Ah, and if the server version is Forge then it would be coding in an entirely different environment right?

[brave sparrow]

Forge and spigot are totally unrelated yes

[viral crag]

too short if anything

[brave sparrow]

If they’re short then it should be apparent where the returns are, and the exit conditions should be documented

[viral crag]

i agree

[brave sparrow]

An early return is no different from throwing everything inside one big if statement, it just makes the indenting more annoying

[crude loom]

Ah I see, thanks!

[ivory sleet]

Maybe one of the Files functions could help you out

[brave sparrow]

Which is harder to read:
if (a != null) {
if (a.b() != null) {
if (!a.b().c()) {
//stuff
}
}
}

Or

if (a == null) return;
if (a.b() == null ) return;
if (!a.b().c()) return;
//stuff

[ivory sleet]

Files::newDirectoryStream or perhaps Files::walkFileTree zacken

[brave sparrow]

Correct

[ivory sleet]

well, most compilers do compile down to the former iirc

mostly due to performance but yeah

[brave sparrow]

https://docs.oracle.com/javase/8/docs/api/java/io/File.html#listFiles-java.io.FileFilter- @quaint mantle

[brave sparrow]

But that’s not for the human to read

Lol

It also gets compiled to bytecode, but that doesn’t mean our actual source should be a bunch of bytecode

[ivory sleet]

yeah

n yeah File::listFiles is probably fine for your case zacken altho not particularly scalable

[tardy delta]

nullable operators when

[ivory sleet]

never

Optional can help you out instead (with a bunch of flatMaps)

I literally gave you two reliable api methods but sure

[tardy delta]

a?.b?.c() looks a lot cleaner than Optional.ofNullable(a).map(a::b).map(b::c).orElse(null)

[ivory sleet]

I agree

but Java's null is unoptimized alr

so idk

[buoyant viper]

i personally use

[tardy delta]

dunno what the difference is between flatmap and map tho

[buoyant viper]

[ivory sleet]

flat map is a monad

map is not a monad

[tardy delta]

lemme translate that

what does monad mean?

[ivory sleet]

basically
(M<T>, T -> M<R>) -> M<R> is a monad

or in Java

class M<T> {
  public <R> M<R> flatMap(M<T> this, Function<T,M<R>> function) {
    //TODO
  }
}```

M<T> this can be removed so

class M<T> {
  public <R> M<R> flatMap(Function<T,M<R>> function) {
    //TODO
  }
}```

simply

map is just

(M<T>, T -> R) -> M<R>

[tardy delta]

lol thats not simple

[ivory sleet]

so <R> M<R> map(M<T> this, Function<T,R> function) instead

basically flatMap is a computation builder, whilst map is not

[tardy delta]

https://www.baeldung.com/java-difference-map-and-flatmap :)

[ivory sleet]

ye

[desert musk]

im makin a plugin where a user can select where they want to respawn after death

[tardy delta]

is anyone ever using that lol

[desert musk]

how should i go about making a "limbo" world or thing so that i can prompt them and receive their answer

[ivory sleet]

yes

there are Optional religious people

because they simply believe touching null is too low level for Java

[tardy delta]

isnt that a kind of disease? 🤔

[ivory sleet]

idk

I mean depending on pov it could make sense

[tardy delta]

i believe even satan is afraid of doing that

[desert musk]

lol

[ivory sleet]

myeah

well it wouldn't be bad if Java added null chain operator

but its probably low priority

[crude loom]

How does the plugin know what is the correct usage and when to send the message of wrong usage from the plugin.yml?

[ivory sleet]

might be added in jdk 69 or sth

[tardy delta]

kek

[ivory sleet]

cuz they scarcely add newer features such as those

they mostly observe other languages and how those features are seen upon by respective language developers

[tough crane]

Hey ,
does anyone have a site / support to learn how to use APIs between plugins? and learn what an "api" is? ^^

[ivory sleet]

cause they want to add necessary and non rushed features (where there have been proper theory around it), unlike a certain language Kot...

[tardy delta]

lin..

[wet breach]

I don't

[ivory sleet]

well I dont think thats possible with plugin yml

just the usage

but thats for /help

so in reality you would need to manually prompt a given command sender the appropriate messages

[ivory sleet]

hmm I mean apis from other plugins is just code where you're only exposed to an abstraction

not much different from normal code

learning them takes time as they are all a bit different in terms of design and depending on what the api is for

[tough crane]

basically it's just being able to add events from other plugins to my plugins?

[ivory sleet]

there's no general way to suddenly fully unlock knowledge for every api that presently exists in this world

hmm

to some extent

[viral crag]

... can you access other plugin handlers ?

[ivory sleet]

but like an api is a very foggy term

[quiet ice]

what sort of handlers?

[ivory sleet]

think they mean custom event classes provided by other plugins

[quiet ice]

event handlers?

[viral crag]

event handlers in this case

[quiet ice]

As in event listeners or the event handler list in an event class?

[ivory sleet]

Bukkit::createWorld which takes a WorldCreator, so look at that if you wanna create a world

[tough crane]

okok , thanks :p
i think i'll just jump into it and see what happens haha

[ivory sleet]

might be worth doing it eagerly, as soon as the server starts since creating a world can lag a bit

Tasic thing is, a mere Java class alone can be seen as an "API" from the view of other classes

[viral crag]

either; seems like a bad idea allowing an unassociated plugin to commander another plugin

[quiet ice]

It could be useful so not that bad of an idea - just depends on the circumstance

[viral crag]

that is true also

[quiet ice]

Do you want to spoonfeed a block change to a specific block logging plugin? This is one way to do it without using their API

But it should be possible to do

[sharp bough]

@ivory sleet hey if im trying to keep a json in memory for quick access of a lot of data moving arround consantly, is it better to use normal json for example:
https://pastecord.com/viqahisaqo.cs that would generate the image, or learn gson and use that instead?

[ivory sleet]

whats normal json?

simplejson?

[sharp bough]

JsonObject() and JsonArray()

among others

[ivory sleet]

those are not normal

[sharp bough]

but mainly those

[ivory sleet]

they are not contained within the java library itselfg

those are from a dependency

what is the name of that dependency?

anyhow yes I would strongly encourage learning gson, or jackson or moshi, those three are the ones most devs out there use in fact

so being knowledgable in those particular three wont harm you

[sharp bough]

com.google.gson.JsonObject

[ivory sleet]

thats gson

you're just using an arguably legacy way of dealing with the json tree structure

[sharp bough]

and by any chance do you know which one i should use if i want a lot of data moving around efficiently?

otherwise im gonna google a few things

[quaint mantle]

When using saveResource("example.yml", true/false);
What does the true/false do ?

[tender shard]

replace eixsting

[vocal cloud]

Liver failure

[ivory sleet]

@sharp bough type adapter

mainly

[vocal cloud]

Constant state of failing liver

[sharp bough]

igh thanks

[vocal cloud]

Or is it kidneys

[viral crag]

poor vitamin and lack of exercise creating a storage of uric acid - ideally the whites of your eyes should have a blue tinge

[quiet ice]

My personal favourite for json parsing is org.json:json. But I am sure a lot disapprove here

[wet breach]

it be kidneys and their condition if their eyes are yellow would indicate jaundice

[viral crag]

oh, your just a mongrel 😛

not aware of any health related things to iris color other than cataracts - oh and glacuoma

someone will still think you are pretty

...

[wet breach]

ah you are one of the rare people then

[echo basalt]

in the file thats already created, it wont replace them, but if it has new content thats not there, it'll add it, right?

[tender shard]

no

it will overwrite the existing file if the parameter is set to true

and if it's false, it will say "could not save resource asd.yml"

[quaint mantle]

Aha, understood.

[echo basalt]

only good use-case scenario is restoring to defaults if the file is invalid

but there are much better ways to do it

[quaint mantle]

But can you like compare them somehow ?

[viral crag]

you can read from the file, are you expecting them to be different?

[crude loom]

What is the common way to show the user the list of the plugin's commands and syntaxes?

[tender shard]

what are you trying to do?

[tender shard]

make a help command that shows all commands? 😄

[viral crag]

doccumentation and a wiki?

[crude loom]

Yeah that works, thanks!

[crude loom]

Yeah but I meant more for the common server user

[viral crag]

yeah you can dump em in the plugin.yml or use annotations

[crude loom]

Wait but the help commands shows the description and usage of the command

How do I show the syntax?

[tough crane]

what is a file pom.xml in plugins opensources ? i can add repository and dependency inside

[viral crag]

comments of the response

[tender shard]

it's telling maven how to build the project etc

[tough crane]

sorry if i'm super dumb but i'm trying to learn 😂

[crude loom]

What do you mean?

[quaint mantle]

If for example some values are not the same, replace them and keep the rest of the content.

Or would it be better to use a database for things such as creating mines and stuff?

[tough crane]

ok so this is where I add the dependencies and libraries of my api or libs?

[grim ice]

yeah

basically ur configuration file that maven uses to turn your project into a jar file

simplest terms

[viral crag]

sender.sendMessage("Contributors are currently: " + plugin.getDescription().getContributors()); etc

[crude loom]

Ah, and this I do where?

[grim ice]

i need

a library idea

i cant

[viral crag]

https://www.spigotmc.org/wiki/create-a-simple-command/ unless you want to use annotations, then its different

its a part of spigot

https://hub.spigotmc.org/stash/projects/spigot/repos/plugin-annotations/browse

i currently am playing with using annotations now

[vocal cloud]

I have a library for annotations to register everything

[viral crag]

yes it generates it's own plugin.yml looks like this for commands @Command(name = "contributor", desc = "Contributor Command", aliases = {"SAcontributor"}, permission = "QuadArrows.contributor", permissionMessage = "You do not have permission!", usage = "Only returns authors")

then you only need your CommandExecutor

[fallen sandal]

..

[viral crag]

i originally thought it might be that way too

[fallen sandal]

                    //ab.addField("Cannot Retrieve Online Players..", "", true);
                    ab.addField(p.getDisplayName(), "", true);

                }

                else {
                    ab.addField("Cannot Retrieve Online Players..", "", true);
                    
                }``` in this code

[viral crag]

oracle seems to have had other ideas

[quiet ice]

oracle?

[tardy delta]

Integer.parseInt(String.valueOf(1))

[quiet ice]

don't worry, it's commented out

[fallen sandal]

when someone playing in my server like if 1 or more than 1 player is playing its sending embed message

but if no one playing its not sending any message

[fallen sandal]

should i use this?

[tardy delta]

lol no

[quiet ice]

nonono

[fallen sandal]

lol

[viral crag]

annotations is at the base an oracle thing

[tardy delta]

what are you even doing

[quiet ice]

Yes, but nothing prevents you from acctually doing it like proposed

[tardy delta]

::isEmpty kek

[quiet ice]

It's not an oracle limitation but a plugin-annotations limitation

[fallen sandal]

what should i do .-.

[quasi flint]

::isEmpty

[quiet ice]

Are you sure that the lines of code are called when there are no players online?

[fallen sandal]

ok

[quiet ice]

Also beware that getOnlinePlayers can be inaccurate in some conditions

[fallen sandal]

yes maybe cause when 1 player is playing its sending exact embed message i wanted

but when the player is less than one or noone playing its not sending any message

[tardy delta]

when?

[quiet ice]

Player being dead for example

[tardy delta]

ah

[quiet ice]

It makes sense given that there is no player entity, but under some circumstances it can be an issue

[mellow edge]

is possible to kick the person from the server if he refuses costum resource pack download

[quiet ice]

So you are not sure?

[fallen sandal]

no

[quiet ice]

Just throw a few sysouts at it and check if it is called

[fallen sandal]

trying this if (Bukkit.getOnlinePlayers().size() == 0)

[quiet ice]

1.18 has this natively

[viral crag]

its a server option if i recall

[quiet ice]

hm?

[mellow edge]

ok

[fallen sandal]

still same

[quiet ice]

are you sure this is called?

[fallen sandal]

yes

cant i send image here?

[low temple]

Maybe #isEmpty() might make more sense

[quiet ice]

It's not of relevancy

[low temple]

I forget what data type Bukkit.getOnlinePlayers() returns tho

[quiet ice]

Player most likely

[low temple]

Yeah but is it an array of players or List?

[tardy delta]

Collection<? extends Player>

so craftplayers

[quiet ice]

@fallen sandal Actually, could you just send the whole code?

[low temple]

Yeah then you can use #isEmpty()

[fallen sandal]

mm

[fallen sandal]

wait

[quiet ice]

and they were never seen again

[viral crag]

why not just add/subtract from a scoreboard objective?

[fallen sandal]

my internet sucks

[quiet ice]

Then using discord may not be the wisest choice

[fallen sandal]

my dc was glitched lol

[quiet ice]

Ah

this explains it

[fallen sandal]

what

[quiet ice]

Your Bukkit.getOnlinePlayers().size() == 0 is called for every online player

[fallen sandal]

yes

[quiet ice]

And if there are no online players?

[fallen sandal]

ab.addField("No one Playing..", "", true);?

[wide coyote]

its in the for loop

[quiet ice]

Nope! It will never get called

[fallen sandal]

ah

[quaint mantle]

Are we allowed to limit the amount of IPs a plug-in can be used on?
I want to try and prevent paid plugins from being leaked, but am not 100% sure if spigot allows for this.
Whilst this is not going to stop everyone, it may stop people that don’t understand Java very well

[tender shard]

leakers will just remove that code

[wide coyote]

you can listen for InventoryClickEvent and InventoryDragEvent

[fallen sandal]

cant i use else in anyway? .-

[wide coyote]

thats probably what is you are looking for

[quiet ice]

You can, just outside your for loop

[quaint mantle]

I know they will, more looking to stop people sharing between friends
Could perhaps render plugin versions more than x versions out of date useless to slow the spread of leakers

[sharp bough]

so i tried moshi and gson, i dont fully understand whats going on and the docs and not that clear i think, so is using the legacy version of gson that bad? its my easiest option

[vocal cloud]

I always say. Show me a plugin that has some anti-copy prevention and I'll show you a cracked plugin lol

[sharp bough]

it would be for a beta version of the server, so not that much usage

[ivory sleet]

nah not bad

[sharp bough]

mm i think im gonna use that

[fallen sandal]

but how to define the value of Player p outside the loop

[quiet ice]

You do not even need p

At least not there

[fallen sandal]

Player p = Bukkit.getOnlinePlayers();

??

[quiet ice]

if (players.isEmpty()) {
    // Empty!
} else {
    for (Player p : players) {

    }
}

Would be how I would do it

[fallen sandal]

ok

[quiet ice]

Unless you want to send that JDA message for every online player

At which point you just need to move the if statement over the for loop

[tardy delta]

if (players.isEmpty()) {
    // Empty!
} else for (Player p : players) {

    }```kekw

[ivory sleet]

else for

[fallen sandal]

Incompatible types. Found: 'org.bukkit.entity.Player', required: 'java.lang.String'

[tardy delta]

i did else try to

oh not pushed to github yet

kekw

[ivory sleet]

oh god

that looks so cursed

I can of sth like else var x = 1; also

holy crap

ew

[fallen sandal]

okay so

i had changed some stuff and made like the old one

                // Empty!
                ab.addField("No one Playing..", "", true);
            } else {

                for (Player p : Bukkit.getOnlinePlayers()) {

                    ab.addField(p.getDisplayName(), "", true);
                }

            }```

and its working what i wanted

thanks for help :))

[fierce glacier]

how to add a potion effect to a monster please ?

[brisk estuary]

Does anybody know how can I use javax.annotation classes? I'm using Intellij IDEA but it doesn't recognize the availability of these classes via maven dependency and the imports are shown as unavailable. How can I fix it?

[fierce glacier]

thank !

[sacred mountain]

thats a thing?

[tardy delta]

ye because you dont need brackets for an if else

[sacred mountain]

o

[tardy delta]

if (true) { doSomething(); }
if (true)
    doSomething();```

if (true)
    doSomething();
else try doSomeException();
catch (Exception e) {}```
would probably work

[sacred mountain]

damn

do you guys put spaces in between operations

like a+b or a + b

[tardy delta]

spaces

[sacred mountain]

good

[tardy delta]

without is horrible

[sacred mountain]

yes exactly

[vocal cloud]

Ctrl Alt L

[tardy delta]

doesnt do anything

[vocal cloud]

formats the current file

[strong parcel]

Is it possible to have text both bold and underlined in a written book?

I have tried ChatColor.UNDERLINE + ChatColor.BOLD, but Java does not like that.

[hexed hatch]

put a blank string between them

• "" +

[tardy delta]

or call toString explicitly

[strong parcel]

That worked. Thanks!

[spring minnow]

i have a problem with an event etting called twice

can someone send me the ' thing cuz idk how to do it on italian keyboard?

so i send the code

xDDD

[plush gulch]

is there an event that triggers when a sound is played or when a player hears a sound?

[spring minnow]

mhh, i don't think so

never heard of it

also, would be quite difficult to manage

imagine that in a whole server like everything plays a sound, imagine mananing that xD

even if you had an event like this you wouldn't be able to detect what made it for the all things that makes sounds

what do you need it for?

[plush gulch]

I want to make a challenge for myself to hear all minecraft sounds

do you know if something like this exists in modded?

[spring minnow]

wait what

and you would to make like that every time a sound is played, you get a warning?

something like that?

@,@

[plush gulch]

well every time a new sound is played its checked off the list

[spring minnow]

oh

i don't think there is a way to do that

i also checked the event folder of bukkit do be 100% sure and there is no event for this

[vocal cloud]

Forge has a client sound event

[plush gulch]

thanks for checking anyway

[plush gulch]

ok, onto forge then. thanks

[spring minnow]

np

MikeTheShadow

[vocal cloud]

hm

[spring minnow]

can you send me the ' thing
