[ivory sleet]

Ofc lol

[buoyant viper]

do Sets just store their data willynilly then?

[young knoll]

For example a hash set is backed by a hashmap, and hashmap aren’t ordered

[lost matrix]

A set could look like this
(1, 3, 2)
Then you remove '2' and add '2' and it could look like this
(2, 3, 1)

[brave sparrow]

Sets have no guaranteed order

[ivory sleet]

AsynchronousSynchronousNonBlockingBlockingCollectionQueueSet (:

[brave sparrow]

Some of them may have an order due to implementation but they are not guaranteed to do so

[young knoll]

You can technically be really janky and access by index though like

[buoyant viper]

java.util.HashList when? /j

[young knoll]

toArray or an iterator

[brave sparrow]

That would be pointless lol

[young knoll]

But there is no guarantee as to what’ll happen if you do

[brave sparrow]

If it has an order then the hash does nothing

[sullen marlin]

LinkedHashSet?

[buoyant viper]

no duplicates

[buoyant viper]

is that a thing

[worldly ingot]

I was gonna say. LinkedHashSet would like a word lol

[brave sparrow]

Yeah that’s a thing lol

I thought you meant on top of that

[keen horizon]

how do i make something only happen when shifting

[lost matrix]

Sets are per definition unordered. Some have an order because of their implementation
but this has to be explicitly stated.

[brave sparrow]

^

[brave sparrow]

You check if they’re shifting

[keen horizon]

how

[brave sparrow]

Player#isSneaking

[buoyant viper]

thank u for reiterating what alex said a solid 2 minutes ago

[lost matrix]

Check Player#isSneaking()

[lost matrix]

You are welcome

[worldly ingot]

If we're gonna get technical, this is wrong

[keen horizon]

thanks this isnt gibberish at all

[buoyant viper]

its not

[brave sparrow]

Do you know Java?

[keen horizon]

no

[brave sparrow]

?learnjava

[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.

[buoyant viper]

then that's why its gibberish

[brave sparrow]

Gonna have to learn the language before you can program a plugin in it

[brave sparrow]

?

[worldly ingot]

you can be sneaking without holding shift

[buoyant viper]

yeah, i sneak with Left Alt

[brave sparrow]

Ok fine, TECHNICALLY you are correct

[worldly ingot]

😄

[keen horizon]

i meant sneaking

[brave sparrow]

anyone who doesn’t have sneak bound to shift is a dirty savage though

[buoyant viper]

i sprint with shift

[sullen marlin]

https://tenor.com/view/correct-futurama-the-best-kind-of-correct-yes-yep-gif-5787390

[buoyant viper]

like what most games do

[brave sparrow]

I reiterate

Dirty savage

[buoyant viper]

[brave sparrow]

This is the equivalent of saying “I don’t know how to drive, but I only need to take the car to the mall so I can hang out with the boys”

You either need to learn or find someone to do it for you

[worldly ingot]

Well no I more meant that you don't have to be holding the key to be sneaking 😛

[lost matrix]

"Mum drive me to the mall"

[tardy delta]

better didnt say that

[lost matrix]

Does you mum know how to code?

[keen horizon]

but learning would taketo long i just want to edit thisplugin so it only happens when shifting

[worldly ingot]

Say you're under a half slab

& the server doesn't know what buttons you're holding

[young knoll]

I can just find someone to learn for me?!?!

Heck yeah, choco learn assembly for me

[brave sparrow]

That sounds like dirty 1.9+ behavior

[tardy delta]

is there a reason stuff isnt immutable, ive seen the same thing on minestom and im wondering why

[young knoll]

What does the server think if you are forced into the crawling state

Does it consider you swimming or gliding

[keen horizon]

can u do it for me

[worldly ingot]

Abso-fucking-lutely not

[young knoll]

It was worth a try

[brave sparrow]

No I cannot, but you’re now on the right train of thought

[remote swallow]

no im not doing it for you either

[keen horizon]

do u not know how?

[brave sparrow]

Does this happen in 1.8? I didn’t think that would trigger sneaking

[lost matrix]

Use GOTO a lot. It makes your code clean and readable.

[worldly ingot]

Cause we can change it

[young knoll]

Dynamic recipe outputs

[brave sparrow]

I know how, I just don’t have the time to spare on that

[keen horizon]

mmmm ye suree

[tardy delta]

im wondering what for, cuz does changing it have to resend the update recipes packet?

[worldly ingot]

I dunno. Although what I'm hinting at is that the client has no clue you're pressing the shift key. Your client could send a packet saying you're sneaking no matter what key you press, if any at all. The state of sneaking != holding shift

I'm trying to win on technicality here lol

[brave sparrow]

What kind of assembly, you didn’t specify

[worldly ingot]

Terminology

[brave sparrow]

https://tenor.com/view/actually-bored-ackchyually-gif-14423655

[worldly ingot]

EXACTLY

[tardy delta]

i could probably just have an abstract getResult method instead of having a common field which isnt used anyways when overriding it 🤓

[keen horizon]

can anyone here do some simple codingfor me pls its not a lot its just checking if they sneakin to do the thing in the plugin

hehe i found my sources to steal borrow code from

[worldly ingot]

I mean... I wouldn't necessarily recommend basing your stuff on CB

The CraftInventory stuff is scary

[tardy delta]

just need some impl details

[young knoll]

gbz80

[worldly ingot]

The impl details are a little sketch too as Minecraft has evolved. null vs AIR constants in 1.14 for instance

[young knoll]

When do we get a PDCRecipeChoice?

[remote swallow]

what would that even be

[buoyant viper]

[brave sparrow]

https://rgbds.gbdev.io/docs/v0.5.1/gbz80.7/

[tardy delta]

we have air returning on minestom

[young knoll]

The pdc of the ingredient and the item you’re using have to match

[tardy delta]

kinda weird to do Arrays.fill(stacks, Material.AIR)

[remote swallow]

how would minecraft render that

[young knoll]

Well, more specially a single key must match

[brave sparrow]

I remember having to do a binary search in ARM for homework, such a PITA

[young knoll]

Yeah fair point it would be hard for the user to tell

But I mean, is ExactChoice shown any differently from just a regular material?

[remote swallow]

dont think so

i think if you had pdc, you would need to also pass a List materials

so cb could tell the server what to render

[young knoll]

The recipe book just renders a ghost of an item, right?

[tardy delta]

who thought it was a good idea to only have light mode on stash

[young knoll]

Not the tooltips or anything

[tardy delta]

cmon man its 1 am

[remote swallow]

yeah

[remote swallow]

you have litemode stash?

ratio?

[young knoll]

Simply time travel

Not everyone uses dark reader

[remote swallow]

well

they should

[remote swallow]

we need a stonecutter api update

@worldly ingot when

[young knoll]

What would it do

[tardy delta]

what api

[worldly ingot]

For?

Stonecutters are kinda featureless on the server side

[remote swallow]

specify the stone cutting options of an item

[young knoll]

You can already add recipes to it I believe

And it has a single slot

[buoyant viper]

woodchopper block when?

[worldly ingot]

Yeah that's done via addRecipe() iirc

[remote swallow]

ah

[tardy delta]

messed up stonecutter

[worldly ingot]

I think we have a StonecutterRecipe?

[young knoll]

Yeah stonecutters are just a crafting table basically

[tardy delta]

yas sir

[young knoll]

But with a fancy UI and the ability to castrate you

[tardy delta]

im kinda triggered to abstract away stuff today

while i shouldnt

[buoyant viper]

personally, i love it for the second option 🏳️‍⚧️

[tardy delta]

its 2023 man

[young knoll]

No that’s the less demonic version of a furby

Well, debatably

[tardy delta]

im probably making some stupid decisions now which i'll regret later

uh oh craftbukkit doesnt have the group field in the recipe class either :(

am i the only one waiting for c++ style default args in java?

[young knoll]

I doubt it’ll happen

[tardy delta]

same

[young knoll]

Java just uses overloading for the sameish result

[tardy delta]

but atleast we got string interpolation now

[young knoll]

Do we?

[tardy delta]

https://openjdk.org/jeps/430

or whatever its called

probably going to be implemented

well i hope so

[young knoll]

Nice

That’s a feature I miss from C#

[tardy delta]

all the companies i went are using c# lol

🥹

[young knoll]

I want https://openjdk.org/jeps/441

[buoyant viper]

we do?

[young knoll]

Looks like we’ll have it in preview soon

[tardy delta]

what does that one do? ive seen so many pattern matching for switch previews

[young knoll]

static String formatterPatternSwitch(Object obj) {
    return switch (obj) {
        case Integer i -> String.format("int %d", i);
        case Long l    -> String.format("long %d", l);
        case Double d  -> String.format("double %f", d);
        case String s  -> String.format("String %s", s);
        default        -> obj.toString();
    };
}

[remote swallow]

is that not in 21 preview

bc 21 dev builds are out

[tardy delta]

i have that in java 17 preview afaik

[young knoll]

It’s gone through 4 previews

17,18,19,20

[remote swallow]

and 21 is lts so we might be getting a java update in 1.20 or 1.21

[tardy delta]

i also remember that "when" thing

i dont wanne be the one implementing it

[young knoll]

Stuff being in preview 700 times is pain

:(

[young knoll]

If we don’t I’ll book a trip to Stockholm

[tardy delta]

go visit conclure

[remote swallow]

yeah

[tardy delta]

or is that another country

[remote swallow]

both are sweden

[tardy delta]

i better go to sleep bruh

before i throw my pc out of the windows cuz some dude sealed his interface i was planning to use

[young knoll]

I mean idk if Mojang will have any reason to push java forward even more

[remote swallow]

latest support

[young knoll]

Most companies don’t bother

[remote swallow]

were on 17 atm arent we?

[young knoll]

Yes but I assume they wanted something from 16

[remote swallow]

17 is supported until 2026 and extended supoprt til 2029

[young knoll]

Most companies don’t see the new features being worth the effort

[remote swallow]

so are we jumping to next lts in 2026 or 2029

[young knoll]

Granted, for Mojang they don’t have to update a bunch of live software

So it’s somewhat different

[acoustic falcon]

Hi i have a question about hikariCP what is the best way to get the connection in a Dao for example? if you need more explaining let me know!

[vocal cloud]

In a decentralized autonomous organization?

[acoustic falcon]

dao as like DataAccessObject: https://www.baeldung.com/java-dao-pattern

actualy doesn't matter where you get it

[hazy parrot]

TIL this is called dao pattern lol

[subtle light]

aynone know the name of the plun that when you get hit out of spawn area you cant run back in and it stopps u

[vocal cloud]

Yeah, it's a very complicated method of doing things. I find that kind of pattern is only useful if I'm scaling a large application

[hazy parrot]

isn't it basically using same interface for multiple db impls

that impression i got from fast look over that page

[vocal cloud]

Correct

It's for use with multiple backends and such

Useful for decoupling

[acoustic falcon]

yess but does anyone know the best practice of getting a connection? i am finding many solutions like:
https://stackoverflow.com/questions/44580501/using-hikaricps-connection-pool-the-correct-way
what do you guys think is the correct way to do it?

[real shuttle]

anyone got experience with spawners in servers

If you have a question, please just ask it. Don't look for staff or topic experts. Don't ask to ask or ask if people are awake or available. Just ask the question to the channel straight out, and wait patiently for a reply. Make sure you use the right channel regarding the topic of your question. Create a thread in case the channel is already in use!

[real shuttle]

well i cant get wither-skeleton, iron-golem, cave-spider spawners to work they are just pig spawners when you place them have tried mineable spawners plugin and slik spawners all other spawners work just the ones with two words

#help-server

[tender shard]

how is this related to development?

[weak meteor]

Someone can explainme how to differentiate inventories in inventoryview.gettopinventory()?

like, yes i know it will get the upper inv

but i dont want to make my listener confuse

u know?

So how its supposed to differentiate x inv from y inv?

[tender shard]

by using == or equals

[lost matrix]

Are you doing GUIs?

[weak meteor]

Yep but being honest i dont understand your post on spigot

I just need to listen to 3 invs

[lost matrix]

Well then create those 3 invs and check if(clickedInv == yourInv)

[weak meteor]

Yes, the problem is idk why it doesnt work

it doesnt matter if i click in the player inv or in the custom inv lets say a diamond sword will make the samething

im actually doing this for verification if (e.getClickedInventory().equals(inventoryView.getTopInventory()))

but i know that wont work

because will listen to all the upper inv

not the one i want

there's where my question is

[lost matrix]

This will be true for every top inventory that gets clicked

[remote swallow]

that should be an instance of your inventory

[lost matrix]

If you want == to be true then you can only create your inventory once
And exactly this inventory needs to be opened by players.
Every time you call Bukkit.createInventory() it will create a completely different
inventory and == wont be true anymore.

[weak meteor]

Hmm

this is my code for another listener if (inventory.equals(resultInventory) && player.getOpenInventory().getTopInventory().equals(resultInventory))are you thinking that?

[lost matrix]

No im thinking

if(event.getClickedInventory() == yourCustomInventory) {

}

[weak meteor]

k

lemme try

[weak meteor]

hmm

thats tricky

what i normally will use

a github

for every project

Never tried that

Github isnt a bad option tho

[analog thicket]

Onedrive, i think that takes files from your desktop and puts them in there

cant remember tho

[lost matrix]

100% use git

[weak meteor]

But youll need to be in the same network, right?

Hey, 7smile7

Look a this code

[remote swallow]

onedrive is cloud

[weak meteor]

 @EventHandler
    public void onResultadoClose(InventoryCloseEvent event){
        Inventory inventory = event.getInventory();
        Player player = (Player) event.getPlayer();



        // Check if closed inventory is named "Resultado" and is top inventory of player
        if (inventory.equals(enchanterMenu)) {
            if (player.getOpenInventory().getTopInventory().equals(enchanterMenu)){
                UUID playerUUID = player.getUniqueId();

                // Check if the UUID of the player who closed the inventory matches the stored UUID
                if (playerUUID.equals(storedUUID)) {
                    // Drop the item in the player's spot or inventory
                    player.getWorld().dropItem(player.getLocation(), item);
                }
           }
        }
    }````

I just wanna drop the item if the player closes the inv

but is not work

Just use the desktop app

[lost matrix]

First of all. This line of code is useless:

[weak meteor]

k

[lost matrix]

Next: Where is this "item" coming from?

[weak meteor]

Just a enchantment thing

Yes i know you can enchant with the anvil

i just making a favor for a friend

[lost matrix]

So its a field in your class.
Then this wont work. If multiple players have this inventory open
then they will overwrite each others items

[weak meteor]

I thought that

[lost matrix]

Huh?

[weak meteor]

the same thing

but uuid cant repeat

thats why i use it, just security

[lost matrix]

No what he needs is a proper GUI setup.
He needs to create one separate inventory for every player.

[weak meteor]

damn

[lost matrix]

Use a GUI library

There are plenty out there

[weak meteor]

i thought of that, that should cover that problem?

[lost matrix]

If you want to write your own then follow my tutorial.
You just need to sit down and learn some more java for that.

[weak meteor]

Hmm

yes thats right

[remote swallow]

imo if you dont want to use a lib, you want a class that implements Listner, constructor with JavaPlugin to register the listener, Save the inventory to a class variable and check if the inventory is the same

[lost matrix]

Controlling the events is the easy part. Your listener should not be bigger than this:

[remote swallow]

abstract class

[weak meteor]

You never thought of making a video tutorial?

[lost matrix]

Not really... I can see the appeal of videos but thats just too much unremunerated work

[remote swallow]

text + images is better imo

[weak meteor]

Okay, question, how does this work?

Map inventories to their handler

this

not the image

[lost matrix]

Your key is the vanilla inventory and your value is any implementation of the InventoryHandler interface.

This is an example for some implementation

You can just follow the tutorial step by step and change what you need to change honestly.

[weak meteor]

Okay

Thanks

[weak meteor]

From here now i can make the thing i was thinking?

[native gale]

I already asked this question before, but seems like nobody noticed so I'll ask again. Given that I know for sure that a block at a given Location is a bed, how do I get the Location of the second half of that bed?

Like, none of these API methods are very helpful https://hub.spigotmc.org/javadocs/spigot/org/bukkit/block/data/type/Bed.html

Some people on the Internet suggest to just check what part of bed it is, and check in all directions where is the another part

But this solution would fail 75% times in cases like this

[sullen marlin]

Idk check how vanilla does it

[static ingot]

It extends Directional

So just get the block in the direction that the bed part you have is facing

assuming both parts face inwards anyway.. i'm not sure if that is really the case. it's still easy to work out either way

[wet breach]

I believe both parts face the same way

so you if you get the head part you need to get the opposite direction

if I recall

[native gale]

That's right

[native gale]

Thanks, it is the solution

[static ingot]

Does TextComponent support line breaks?

[rough ibex]

Try it and see

In titles, no

The client will display it as [LF]

[halcyon hemlock]

[halcyon hemlock]

yes

        } catch (FileNotFoundException e) {
            throw new RuntimeException(e);
        } catch (IOException e) {
            throw new RuntimeException(e);
        }

        EditSession editSession = WorldEdit.getInstance().newEditSession(BukkitAdapter.adapt(l.getWorld()));
        try (editSession) {
            // Saves our operation and builds the paste - ready to be completed.
            Operation operation = new ClipboardHolder(clipboard).createPaste(editSession)
                    .to(BlockVector3.at(l.getX(), l.getY(), l.getZ()))
                    .ignoreAirBlocks(true)
                    .build();


            try { // This simply completes our paste and then cleans up.
                Operations.complete(operation);
                editSession.close();
            } catch (WorldEditException e) { // If worldedit generated an exception it will go here
                System.out.println(ChatColor.RED + "OOPS! Something went wrong, please contact an administrator");
                e.printStackTrace();
            }
        }
    }```

this is my code to paste a schematic right now

I have no clue how to use FAWE/World Edit

[drowsy helm]

editSession has an undo method

im not sure if you can undo after you close the session though

[halcyon hemlock]

editSession.undo(editSession)?

[drowsy helm]

yeah

[halcyon hemlock]

could I do something like this?

    public static void undoLastEditSession() {
        EditSession editSession = latestEdits.get(latestEdits.size() - 1);
        EditSession undoSession = WorldEdit.getInstance().newEditSession(editSession.getWorld());
        editSession.undo(undoSession);
    }

[drowsy helm]

the docs fucking suck

https://www.tabnine.com/code/java/methods/com.sk89q.worldedit.EditSession/undo

i found this

[halcyon hemlock]

yeah lmao

let me try this

ok this works

also for the paste method, where does it paste from

which x,y,z

[drowsy helm]

if youre using ClipboardHolder theres a .to(x,y,z) method

you can append

oh you have it in ur code

[halcyon hemlock]

yeah, I think it pastes from where I copied it

i will copy it from top right corner so its easier to paste it

[halcyon hemlock]

it works ok

[sterile token]

Okay what the fuck the issue in having, is really stupid. The code is not being executed if i remove a sout(), but if the sout() all the code works pefect

🤡

Is that even possible? 🤔

[remote swallow]

i saw something like that happen to someone else, the sysout was delaying the follow stuff just enough for it to work

[sterile token]

Could caused because of an executor? 🤔

[azure wedge]

Hi, noob with java but not with programming at all. I'm used to use VS. Just a simple question: How do i find all available EventHandlers? for example there is a tuto that implements "onJoin" which is when a player joins the server but i can't seem to find that event is called or even more when it's defined. Thanks. PD: using intellij

[sterile token]

For coding spigot plugins, you should import the spigot api, without it you cant code plugins because its contains everythings the events api, plugins api, etc

[wraith star]

why does translateAlternateColorCodes suddenly not work

like

[sterile token]

Not work? Details please

[river oracle]

it doesn't just "not work" so your are doing something incorrectly

[wraith star]

package club.crestmc.neptunediscordlink.util;

[worldly ingot]

👏 Don't 👏 use 👏 legacy 👏 symbols 👏 in 👏 components 👏

[wraith star]

wdym

what legacy symbol am i using

[worldly ingot]

&f, etc. = legacy

[river oracle]

how would you reccomend making good configuration with components

[wraith star]

yeah

thats not what i came here for

[worldly ingot]

rn you don't

No I'm saying don't because you can't

[wraith star]

im pissed off because i spent the past 3 hours trying to fix this error

i could literally punch someone right now

[river oracle]

just dont' use components if they have no easy config

[wraith star]

so just use the deprecated option?

where you just send a string?

[river oracle]

ewww

he is using paper api

nah go ask paper

[wraith star]

i'm using bungeecord

for this

[river oracle]

oh then yeah just use the deprecated option

[sterile token]

What can cause a code of block not being executed when i remove a system out? Because its happening that on my code, and its really weird

[river oracle]

and supress it

[eternal oxide]

Use String, eff paper, this is Spigot

[river oracle]

he is using bungeecord

[wraith star]

but what doesnt make sense

[eternal oxide]

ah, then learn bungee 🙂

[wraith star]

is whenever i run the following command it throws an error related to translateAlternateColorCodes ```java

[worldly ingot]

Usually that happens when it's a race condition

[sterile token]

Right, could be a completable future causing it?

[eternal oxide]

Its usually when you synchronize on two different objects

different places in your code

[sterile token]

makes sense cuz im using CompletableFuture

[azure wedge]

I think my issue is not correctly explained. Where do i find events handlers at all, like if there is an onJoin i want to know the sintaxis for the event when a player leaves

[eternal oxide]

one locks the other out

[river oracle]

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

[sterile token]

Do you want to see my code?

[eternal oxide]

do you use the synchrnoized keyword anywhere?

[azure wedge]

Sorry im way too new with java and intellij, is that a command?

[wraith star]

im going to freak the fuck out

theres no reason this shouldnt be working

[river oracle]

learn java before using spigot

[eternal oxide]

?paste your code then

[undone axle]

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

[river oracle]

just stick with legacy text and delete any component references 🤷🏽‍♂️ could also be that there is weird compilation stuff going on

[sterile token]

right thanks man i have been many hours with this shit

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

Its really simple what im doing but i cant make it work- haha

[eternal oxide]

and whats the exact issue? I see nothign in there that shoudl be problematic

[sterile token]

Im confused too, because some debug messages are not dispayed and some yes

I just invalidated IDE cache, because i thought it was something there can cause this

okay the issue is the next, my code acts like the event wasnt distpached

[worldly ingot]

I'm telling you why it likely isn't working. Legacy text and components do not play well together

[sterile token]

Like if the code wasnt even called 😡

[river oracle]

he's not calling the method relating to the referenced issue, My guess is compilation issues or simply user error to replace the jars. Unless Bungee just doesn't straight up support legacy

[eternal oxide]

do you have a large enough thread pool?

[sterile token]

I assign it as 20 by default, its okay?

[eternal oxide]

should be

[sterile token]

Those are the output while executing, but if you see carefully my arrive data debug (a sout, is not displayed)

while its making me think, that the message is not being published

[eternal oxide]

are you doing the send and recieve in the same thread?

[sterile token]

no

Im an executor by default in case you dont privde your own

So you can have an idea

[eternal oxide]

get client? shoudl you not be using your own pool there?

I've not used redis but that looks wrong

[sterile token]

What? You mixed me there with the question

Im already using JedisPool if thats your question

[eternal oxide]

yes you shoudl be calling getResource() on your jedis pool

from what I'm seeing

[sterile token]

Yes

Im doing there on the 2nd picture

Inside of try because its auto closed the resource, so then its availabile for next usage

[eternal oxide]

lastly, are you creating a new subscription? or just using one?

[sterile token]

when you initialize the lib, im passing the next params, then interally im subscribing to each serve from the servers you given, plus an extra channel named as: plugin-sync:global, in this case

[eternal oxide]

If you are not renewing your subscriber then I see nothing wrong. You'll probably want to wait for 7smile7 as he's a redis guru

[sterile token]

okay, aparently i fixed the broadcast part, im happy - Thanks for trying to help

Now i need to fix the part which allows you to forwards message to a specific server

[sterile token]

Hmn i cant understand the reason of what happening 😡

Now the messages are received as they want, like if my conditions where insibles 💀

[eternal oxide]

received as they want? Do you mean they are arriving out of order?

[quaint mantle]

hey, i have a problem.

The IDE won't highlight syntax.

[remote swallow]

intellij?

[quaint mantle]

probably because the power went out right as I was starting up the IDE, my whole pc had shut off.

[eternal oxide]

clean cache

[quaint mantle]

how?

[eternal oxide]

what IDE?

[quaint mantle]

intellij.

what most people use probably.

[eternal oxide]

I use Eclipse 😉

[quaint mantle]

oh.

okay.

[eternal oxide]

https://www.jetbrains.com/help/idea/invalidate-caches.html

[remote swallow]

intellij :

file -> invalidate caches

[quaint mantle]

its not working.

[river oracle]

Restart your pc

[quaint mantle]

i just booted up my pc.

[river oracle]

IntelliJ moment

VSCode baby 💪

[quaint mantle]

i use vscode for a few other projects in other languages but not java most of the time.

i would probably prefer to not have a headache.

um

https://imgur.com/QrhriOK

how do i fix this, if anyone knows?

[eternal oxide]

I would guess a file corruption

[wet breach]

re-install the ide, and do a chkdsk on the command line

[quaint mantle]

somebody might have tripped breaker or something right as i was doing that.

[wet breach]

ok and?

[quaint mantle]

i am so annoyed today.

sorry, about that, i just feel kind of stressed out right now.

[sterile token]

My logic is the next, im doing it via 1 default channel (used for global plugin communication) and 1 channel per client let say. They looks smth like:

1. <identifier>:global - Is aways subscribed to it
2. <identifier>:<server> - Its subscribe to each channel getted from the servers you pass before initializing the message broker

[wet breach]

invest in a power back up unit

[quaint mantle]

ok the IDE syntax highlighting and autocompletions issues seem to be fixed now.

that aside though.

i am trying to implement an anvil GUI.

how do i get the two slots in the anvil for putting items/enchanted books to combine?

[eternal oxide]

slot 0 and 1

[quaint mantle]

thanks.

should a PreparedStatment be created in an async thread or is it just okay to create one in the main game thread?

not using one, just creating one.

[ornate parcel]

Hey guys! where can i see the tutorial on how to install the plug-in?

[buoyant viper]

you just drag and drop the plugin jar into the servers plugins folder

[rough ibex]

and then restart the server, if it's still running

[buoyant viper]

spigot plugin hotswap when? /j

[ornate parcel]

thanks!🫶🏻

[quaint mantle]

how do i get the contents of the textfield of an anvil GUI?

[remote swallow]

if you have an AnvilInventory it should be getRenameText()

[quaint mantle]

do i just cast it to an AnvilInventory?

i tried doing that earlier but it seemed to throw an Exception.

[remote swallow]

you could probably do an instanceof, depends where you need to get the text

[quaint mantle]

this.inventory = (AnvilInventory) Bukkit.createInventory(null, InventoryType.ANVIL, "[Change Name]");

is that looking right?

[remote swallow]

just googled some stuff online and for anvil guis you need nms, i found a lib that might work https://github.com/WesJD/AnvilGUI or a class that might also work https://gist.github.com/Scarsz/2524d755fa3e3adddb5dc46890e340f8

the latter is for 1.8 obsfucated nms so idk easy that would be to update

[quaint mantle]

its just a simple GUI, dont really wanna use another library.

https://imgur.com/nbzbFB0

[icy beacon]

come on you don't need to reinvent the wheel

plus anvilgui is maintained and multiversional

[quaint mantle]

public class RenamingInventoryGUI {

    private AnvilInventory inventory;

    public RenamingInventoryGUI (Chunk chunk) throws Exception {
        this.inventory = (AnvilInventory) Bukkit.createInventory(null, InventoryType.ANVIL, "[Change Name]");
    }
}```

[quaint mantle]

ok.

there does not seem to be one for 1.19.3.

[remote swallow]

im pretty sure 1_19_R2 will be 1.19.3

[quaint mantle]

there is also a 1_19_1_R1.

[remote swallow]

nms versioning is weird, just checked the pom and 1_19_R2 should™️ supoprt 1.19.3

[quaint mantle]

could probably be easier if i can just get the AnvilInventory object.

[quaint mantle]

ok.

so, um, how do i add it to my project?

[remote swallow]

maven?

[quaint mantle]

yep.

is this looking right?

[remote swallow]

yep, top right you should see a M with a reload looking button

hit that

[quaint mantle]

do i need to do anything else to specify that it is for 1.19.3?

[remote swallow]

shouldnt need to, im guessing it grabs the version from server ver

[quaint mantle]

ok.

You should setup some shading for compiled dependencies

In order to avoid conflicts

(If you haven't done it yet)
https://maven.apache.org/plugins/maven-shade-plugin/examples/class-relocation.html

um, how do i get these red underlines to go away?

https://imgur.com/t2A5wi6

[static ingot]

ye. if you just get the itemmeta and null check it then the compiler warning goes away

[quaint mantle]

i dont really use third-party libraries all the time.

[sterile token]

no? The warning tills saying its could be null

Also tried moving !hasCustomModel() return; to an if under that one, but same shity warning

[static ingot]

how could it possibly be null if you null check it yourself, lol

ItemMeta meta = item.getItemMeta();
if (meta == null || !meta.hasCustomModelData()) return;```

[wet breach]

depending on what you are doing or how the code is setup, sometimes the IDE can't always tell if something isn't actually null

however ide warnings are not compile errors

[static ingot]

yea, the IDE can't tell when it comes to methods like #hasItemMeta

[wet breach]

different things

[sterile token]

right, but that why shity @Nulleable exists 🤔

[static ingot]

there's some exceptions tho like Optional#isPresent/isEmpty

[sterile token]

I mean spigot api is weird they use @Nulleable and @urban grotto hen they shouldnt use them, but when you need them to be on they dont exists

[static ingot]

they mark it nullable because it is nullable

¯_(ツ)_/¯

[sterile token]

Maybe my ide is bug 😂

I will try invalidating cache

whats the textfrield? Its smth newer?

[wet breach]

even with those annotations there is still some stuff that can't be predicated that it will or will not be null

I always do null checks on stuff that is outside of my programming

because you just never know

but the IDE is only so smart

[static ingot]

^ i.e.: @NotNull and @Nullable can't tell the IDE to infer that #hasItemMeta relates to the nullility of #getItemMeta, lol

[quaint mantle]

uh.

new AnvilGUI.Builder()
                .itemLeft(createItem(Material.RED_STAINED_GLASS_PANE, 1, "[Cancel]"))
                .itemOutput(createItem(Material.GREEN_STAINED_GLASS_PANE, 1, "[Proceed]"))
                .onLeftInputClick(player -> {
                    player.closeInventory();
                })
                .interactableSlots(AnvilGUI.Slot.INPUT_LEFT)
                .interactableSlots(AnvilGUI.Slot.OUTPUT)
                .title("[Change Name]")
                .text("")
                .onComplete(completion -> {
                    player.sendMessage(completion.getText());
                    return Arrays.asList(AnvilGUI.ResponseAction.replaceInputText(""));
                })
                .plugin(ChunkClaimsPlugin.getThisPlugin())
                .open(this.player);```

how do i prevent the player from taking the item out?

and why is the item in the output slot not displaying?

also, the textfield is not empty.

i might not be able to get it working properly.

[quaint mantle]

Remove interactable slots, those make the player able to interact with them and for so able to take them.

If you want to allow the player put the item but not take the modified item, remove the interactableSlots(AnvilGUI.Slot.OUTPUT)

Btw, Interactable slots seems to be an array, so instead of calling it multiple times, you can directly put the slots separated by coma

[sage patio]

what i did wrong?

[kind hatch]

You're iterating over a list and trying to remove elements from said list while still iterating. Hence the ConcurrentModificationException error.

Take a closer look at the lines variable you have and what you are doing with it.

[sage patio]

thanks

[regal geyser]

does this code make sense or is it complicated comparing to its functionality

[buoyant viper]

Kotlin, the only language that will still make u use nullsafe indicators when you already make sure its not null, nice.

anyways seems fine

[regal geyser]

fr i hate that

[buoyant viper]

could probably make a method like fun giveBow(player: Player) so u dont need to repeat the .addItem code

but just nitpicking

[regal geyser]

u mean make the function and call it when i wanna give the player a bow?

[buoyant viper]

yeah instead of copypasting the 2 calls to addItem

like a really really really small and unimportant nitpick

[regal geyser]

makes sense

ill do it, Thanks xD

[rotund ravine]

Player.giveBow() smh

[rotund ravine]

It usually doesn’t.

[buoyant viper]

PR'ing this method into API, gives player a bow.

[rotund ravine]

Kotlin extension functions nub

[buoyant viper]

true

but why limit it to just Kt or Scala?

[rotund ravine]

True

[quaint mantle]

i did not have them and i could still shift-click to get the items.

the library might be broken.

i just need the text from the anvil GUI textfield, how do i get it?

[regal geyser]

how to fix this

[sage patio]

how i can override a command? (/help)

like this?

it seems EssentialsX is overriding my command

[tawny remnant]

Yo what do i put there

[hazy parrot]

In kotlin you check null value with !==, after that, compiler won't complain

And it makes sense, because === translates to == in java

[remote swallow]

thats bungee

iirc to override you need to register after

[sage patio]

after what

after EssentialsX?

[buoyant viper]

like after ess yeah

[remote swallow]

yeah

[sage patio]

nice, how?

[remote swallow]

scheduler

[sage patio]

waiting for ess to get enabled?

[buoyant viper]

make ur plugin load after essentials ezpz

[remote swallow]

soft depend and/or delay stuff by a few ticks

[buoyant viper]

theres a load-order or load-priority u can set in plugin yml too isnt there

xd

[eternal oxide]

depend controls load order, softdepend doesn't

[quaint mantle]

Other option would be to listen to AsyncCommandPreProcess and if the command is /help or /essentials:help, modify it to be /yourplugin:help

That way if the server doesn't use essentials but other similar, it will still override the /help command

[sage patio]

yea thanks to all for the help, but the main problem my command was not working, i didn't registered it in plugin.yml

after registering help in plugin.yml my command overrides Essentials /help command

[buoyant viper]

of course

we all collectively overlooked the simple problem

[quaint mantle]

Happens a lot actually

[buoyant viper]

yea

[rough drift]

is there a way to batch spawn particles rather than sending a packet for each when using World#spawnParticle

[quaint mantle]

I don't think so, if you want to send a participe to everyone, then you will have to send the packet to everyone.

If you just make it appear server side, the client will see nothing, as he doesn't actually have knowledge on what's going on on the server until the server tells the client

[hard lion]

I'm trying to remove an ArmorStand entity using remove() but it doesn't work. I know armorstands are kinda wacky but like...

ArmorStand armorStand = loc.getWorld().spawn(loc, ArmorStand.class);
armorStand.setSilent(true); 
armorStand.setSmall(true);
armorStand.setVisible(false);
armorStand.getEquipment().setHelmet(eye);
mob.setPassenger(armorStand);```


In the event where its vehicle (the mob) dies:
``entity.getPassenger().remove();``

[tacit drift]

store your armorstands in a list

get the armorstand from there and remove it that way

[hard lion]

so using for(Armostand ... : entity.getPassengers()) should work?

[quaint mantle]

Or the amor stand UUID which persists betwen restarts

[tacit drift]

that's smart too

[hard lion]

it's interesting that it doesn't work only on that specific stand
on other types of them it's fine

[quaint mantle]

Try adding some debug to your code, and see if it's actually being run

[quaint mantle]

your modifying the map while in a loop

[quaint mantle]

can i not do that?

[remote swallow]

need to use an iterator if you need to do stuff to all entries

[quaint mantle]

like this?

for (Map.Entry<String, Integer> entry : cooldowns.entrySet()) {
                if(entry.getValue() > 0) {
                    entry.setValue(entry.getValue()-1);
                }

                if(entry.getValue() <= 0) {
                    cooldowns.remove(entry.getKey());
                }
            }

[hazy parrot]

need to use an iterator if you need to do stuff to all entries

[sage patio]

how i can put this:

ConfigurationSection:
  FieldOne: 50
  FieldTwo: 100
  ...
  FieldSixtyNine: 3450

in this?

HashMap<String, Integer> map = new HashMap<>();

[quaint mantle]

ive never used iterators in java, no idea how

[hazy parrot]

for (String key : section.getKeys(false)) {
map.put(key, section.getInt(key));
}

[sage patio]

right, thanks

[remote swallow]

can you ConfigurationSection.getValues() and cast the object or use Integer.valueOf

[quaint mantle]

Iterator<String> iterator = map.keySet().iterator();

while (iterator.hasNext()) {
  String key = iterator.next();
  //Implemenr your logic
}

[quaint mantle]

while (iterator.hasNext()) {
                String key = iterator.next();
                cooldowns.replace(key, cooldowns.get(key)-1);
                if(cooldowns.get(key) <= 0) {
                    cooldowns.remove(key);
                }
            }

got this but intellij tells me i can use a for loop

for (String key : cooldowns.keySet()) {
                cooldowns.replace(key, cooldowns.get(key) - 1);
                if (cooldowns.get(key) <= 0) {
                    cooldowns.remove(key);
                }
            }

[quaint mantle]

Well, in this case yes, you can use a for each loop, but usually you will use a while

alright

[errant narwhal]

hi i need help how to covect CustomNPC extends EntityPlayer class to bukkit Player?

getBukkitEntity() (if you spawned it)

[quaint mantle]

Hi there! Is there any chance someone can guide me through plugin development? I have a great idea and need some direction. I have followed tutorials and all led to errors that could only be diagnosed by someone who has java skills.

for the people that still use 1.8:
How on earth do i make items unbreakable on bukkit?

[errant narwhal]

can someone help i want make player summon an entity will have all them item like armor , sword and shield can someone help

but when i use "player.getInventory().setContents(p.getInventory().getContents());
player.getInventory().setArmorContents(p.getInventory().getArmorContents());"
an entity not wearing armor just put them into inventory someone help please

[patent socket]

How can I cancel a BukkitScheduler task? Here is my code: https://paste.md-5.net/uhidujilow.java

[hazy parrot]

Use overload which have consumer as arg instead of runnable

[patent socket]

I'm using scheduler

Not runnable

Anyways how do I do that?

[noble crown]

hi, does setVisibleByDefault work on players?

[undone axle]

https://tryitands.ee/

[hazy parrot]

i am aware, but one of you args is runnable

change it to consumer

https://goksi.tech/​‍‍⁠‌​‌‌​⁠⁠​ this is runnable

its void functional interface with no arg, consumer is same but takes one arg

and that one arg is BukkitTask

which you can cancel

[tardy delta]

kinda sucks that you cant modify a map within the callback of computeIfAbsent

[hazy parrot]

i mean point of computeIfAbsent is to put something if it isn't present

how would you modify it

[tardy delta]

i forgot what my usecase was but it was smth with removing data related to eachother

[hazy parrot]

also i just noticed, you are pretty much abusing arrays here lol

[tardy delta]

like transitive dependencies within the same map

[quaint mantle]

is there an event for players trading with villagers?

[hazy parrot]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/inventory/TradeSelectEvent.html is this it ?

[quaint mantle]

ok.

[lost matrix]

You should seriously not use a lambda for this. Here is what you should do instead:
https://paste.md-5.net/izabakaveg.java

Ugh the spam..

?paste

[undone axle]

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

[lost matrix]

Using this is now as simple as

  @Override
  public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
    if (args.length == 0 || args[0].length() > 0 && args[1].length() == 0) {
      sender.sendMessage(ChatColor.RED.toString() + "You need to provide both a selector and text.");
      return false;
    } else {
      if(sender instanceof Player player) {
        UUID ownerId = player.getUniqueId();
        DialogueTask task = new DialogueTask(args[1], ownerId);
        task.runTaskTimer(plugin, task, 4, 4);
      }
    }
    return true;
  }

[ivory sleet]

Probably cause of ConcurrentSkipListMap and ConcurrentHashMap

(I mean still possible, but discouraged)

[lost matrix]

In what way? It already modifies the map...

[quaint mantle]

question, how do i get the location of the merchant from the TradeSelectEvent?

[lost matrix]

.getLocation() most probably

After getting the merchant

[quaint mantle]

there is no function like that i found.

[lost matrix]

if(event.getMerchant() instanceof AbstractVillage villager) {
  villager.getLocation();
}

[quaint mantle]

why not just Villager?

[lost matrix]

Because WanderingTrader is also a Merchant

[quaint mantle]

ok.

[lost matrix]

And both are AbstractVillagers

[tardy delta]

could do it with two calls but whatever

loadTag mutates the tags thats why

[patent socket]

So this should be my code instead?

[lost matrix]

Dont use lateinit if you are not 101% sure that you are initializing the value at the right time

[regal geyser]

what can i do? i aint rlly good in this stuff

even the lateinit got it form the web

[lost matrix]

Dont use lateinit for now

[regal geyser]

i am using it so i can access the class in another class, got any other way to do that?

[quaint mantle]

it does not seem to be working.

how do i prevent players from doing villager trading?

what event do i use?

[tall dragon]

you could probably just cancel the PlayerInteractAtEntityEvent so the menu wont pop up

not sure tho

[quaint mantle]

probably gonna do that.

this chat is kind of dead today or maybe not.

[regal geyser]

di?

whats that

[lost matrix]

Do you want to prevent them from opening the trade menu or do you want them to not be able to trade while the menu is open?

[lost matrix]

Dependency injection

Look at the link

[vital sandal]

is there anyway to get a player device info ?

I seen this in bedrock plugin development so how about java?

[quaint mantle]

just not trade, does not matter if the trade menu is open.

might get this to work though.

ok it works.

is there an event for player killing a mob?

[tall dragon]

i ussually use EntityDamageByEntity for that and check if the mob will die by the damage done in that event

[hazy parrot]

Afaik no

[lost matrix]

EntityDeathEvent -> call getKiller() on the defeted mob

[onyx fjord]

how do u work with nms in gradle multi module project?

im slowly getting tired of it

[young knoll]

Personally I use paperweight userdev

hides

[onyx fjord]

doesnt work well in multi module project

[lost matrix]

for gradle -> same

[young knoll]

Works great for me

[onyx fjord]

do u have any public repo using it

[young knoll]

No

?paste

[undone axle]

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

[young knoll]

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

That’s the main build file

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

That’s one of the NMS modules

[quaint mantle]

is there an event for lava spreading or fire spreading?

[lost matrix]

BlockFromToEvent for Lava and BlockIgniteEvent for fire
Second one is a guess

[young knoll]

BlockFromToEvent for lava

And yeah BlockIgniteEvent

[quaint mantle]

does that work for fire as well?

[young knoll]

.

[quaint mantle]

i mean fire spread.

not fire ignition.

[lost matrix]

If fire spreads then it ignites nearby blocks

[quaint mantle]

hm.

ok.

another question.

does event.getToBlock(); return the block that was there prior to the event occuring or after the event occuring?

[onyx fjord]

👍 i was missing the configuration part

[lost matrix]

The state of the Block returned by getBlock() will have the state prior to the event.
This way you can cancel events and prevent the Block from changing in the first place.

[dry beacon]

is the PlayerTeleportEvent Class triggered before or after the player enters a teleport command?

[lost matrix]

• command is entered
• teleport is attempted
• event is fired
• if cancelled -> dont tp; else -> tp

[dry beacon]

makes perfect sense, could have figured out that one on my own, thank you!

[weak meteor]

Hey @lost matrix i have a question, where should i make all the processes for getting the button lets say and stuff?

MainGUI?

public class MainGUI implements InventoryHandler{
    @Override
    public void onClick(InventoryClickEvent e) {
        int slot = e.getSlot();
        Player p = (Player) e.getWhoClicked();

    }

    @Override
    public void onOpen(InventoryOpenEvent e) {
        e.getPlayer().sendMessage(ChatColor.translateAlternateColorCodes('&', "&f> &aOpened Anvil GUI"));
    }

    @Override
    public void onClose(InventoryCloseEvent e) {
        e.getPlayer().sendMessage(ChatColor.translateAlternateColorCodes('&', "&f> &cClosed Anvil GUI"));
    }
}

[sterile token]

Are you doing a menu api?

[weak meteor]

ye some guis

yesterday he told me my code would bug if multiple players are in the same inv

so i did his tutorial but im trying to understand whats going on

[sterile token]

Yes guis are not so easy as they seen to be

[weak meteor]

yep

[sterile token]

Which tutorial?

[weak meteor]

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

[sterile token]

Can i get it, because i will in some weeks recode my menu api (which im doing public maybe)

So then if you want you can give a try once i recode it

Thanks i appreciate it a lot

[tribal rivet]

Hello i am wondering why i am getting a error message in my code "public void onPlayerRightClick(PlayerInteractEvent e) {
Player p = (Player);
Location loc = p.getLocation();

    Player player = e.getPlayer();
    if (e.getAction().isRightClick()) {
        if (!e.getItem().getType().equals(Material.FIRE_CHARGE)){
            {
                p.getWorld().spawnEntity(loc, EntityType.FIREBALL);
            }
        }
    }
}

}"

[paper viper]

Player p = (Player);

you didnt cast on anything

[tribal rivet]

Wdym? sorry if im dumb im new to coding

[paper viper]

you dont need it either

[sterile token]

You should learn Java before trying to code plugins, not being rude

[paper viper]

just delete that line

[tribal rivet]

yes i do

[paper viper]

??? hes not being rude

[tribal rivet]

because otherwise i get this error:

Location loc = p.getLocation();

it doesnt understand what p is

[sterile token]

He? I didnt said he was rude, you mis read the text

[tribal rivet]

and i want the p do be player

[dry beacon]

replace Player p = (Player); with Player p = (Player) sender;

[oblique falcon]

some hacking clients are able to detect which potion effects player have. how do they do this?

[paper viper]

its PlayerInteractEvent

[hazy parrot]

Tf

[paper viper]

you dont need a sender

[tribal rivet]

yeah i have done that @dry beacon

but it doesnt work

[hazy parrot]

you don't have sender

[tribal rivet]

the sender is in the colour red

[static ingot]

it's an event listener method, there is no sender

[dry beacon]

my bad, didn't see that, yeah, you don't need that since it's not a command ;-;

[static ingot]

use e.getPlayer()

You don't need to cast it, so just Player p = e.getPlayer()

[tribal rivet]

so i should replace the p with e

[sterile token]

What api version are you using?

[static ingot]

no, e is the name of your event and is already defined

[tribal rivet]

rise 6 and future client on top

[oblique falcon]

i've seen videos that shows other players armors and potions

[hazy parrot]

?learnjava

[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.

[sterile token]

What i said from the start - haha, i said not being rude, but if you are new, you should learn java before coding

[lost matrix]

Sry i dont understand what that means

[tribal rivet]

yeah i did that but nothing changed it still doesnt know what p means

[oblique falcon]

some hacking clients are detecting other players potions and showing on screen. how do they do this?

[tribal rivet]

Location loc = p.getLocation(); it eoesnt understnmad what the p means in this statement

[torn shuttle]

you just have to write code with sunglasses on

[lost matrix]

They simply listen to incoming meta data packets.
If an entity gets a potion effect then all players
are notified of that.

[static ingot]

That's not possible if you changed it correctly.

[tribal rivet]

i can show you my new code

[static ingot]

then do that

[hazy parrot]

Dude you should really learn java first, you are making job harder for both you and us

[static ingot]

¯_(ツ)_/¯

[static ingot]

true

[tribal rivet]

sorry

[lost matrix]

1. Never use single letter variables like "e" or "p"
2. You really need to learn the very basics first. Do yourself a favour,

[hazy parrot]

Sorry, not trying to be rude, but you don't even know concept of variable

[tribal rivet]

fixed it

it was my own stupidity

thanks

[sterile token]

Sorry for asking you, but i know you have xp with Redis, im having issue while posting data to each server channel, because they listen to the self data they publishing but also, all servers received the data. But the most weird thing is that im using different channels for them

[lost matrix]

Which redis library are you using?

[sterile token]

Jedis*, i know its really bad, but just for starting, then i will update it to Lettuce

So i have the next channel pattern: <identifier>:global for all servers data and <identifier>:<server> for each server data

[lost matrix]

Show some code of your publisher and subscriber

[sterile token]

right

[weak meteor]

So yesterday i followed your tutorial for GUis and i wanna rlly understand whats going on for just replicating in another plugin but by myself, so, i wanna understand what class is doing. So i have some questions, you matter if you can solve it to me?

[lost matrix]

Sure

[weak meteor]

So, the classes GUIListener and GUIManager are equal to the forum post, but what are they actually doing more than register and unregister the active inventories?

[sterile token]

https://paste.md-5.net/keyovaguke.java - There you have the subscription and publishing logic
https://paste.md-5.net/wedajukeko.java - There you have the message listening from redis
https://paste.md-5.net/zahunihimo.java - Basic implentation example if you are not sure how it works

This is such a stupid question but i have nightmare. Currently ive been around 4hrs trying to fix this problem

Im just trying to implement, that each server doesnt listen to his own published data and also when im sending to a specific server channel, all of the servers receives the data

[quaint mantle]

does anyone know of an easy way to use anvil GUIs?

[sterile token]

Where you doing those diagrams? I always want something like that app name

[quaint mantle]

There's not. You must mess up with nms,, use a library or use chat

[sterile token]

Why chat?

[quaint mantle]

i just need the textfield.

is there no way to get that?

[lost matrix]

This is the most prominent library currently:
https://github.com/WesJD/AnvilGUI

[quaint mantle]

i was using that and you can take the items out.

thats not what i want.

[lost matrix]

You cant

[quaint mantle]

If you want to catch an input of the user, you can use the chat, cancel the chat event and read the input

i was shift-clicking and i could take the items out.

i can show on video.

[lost matrix]

Then you misused the library

I have been using this for years and never had any issues

[sterile token]

Doesnt TextField exists? for anvils

[hazy parrot]

Lucidchart is cool

[quaint mantle]

new AnvilGUI.Builder()
                .itemLeft(createItem(Material.RED_STAINED_GLASS_PANE, 1, "[Cancel]"))
                .itemRight(createItem(Material.GREEN_STAINED_GLASS_PANE, 1, "[Proceed]"))
                .onLeftInputClick(player -> {
                    player.closeInventory();
                })
                .title("[Change Name]")
                .text("")
                .onComplete(completion -> {
                    player.sendMessage(completion.getText());
                    return Arrays.asList(AnvilGUI.ResponseAction.replaceInputText(""));
                })
                .plugin(ChunkClaimsPlugin.getThisPlugin())
                .open(this.player);```

[sterile token]

Oh ok thanks

[quaint mantle]

this is what i was doing last time.

i was able to shift-click and take the items.

[quaint mantle]

That requires NMS or use a library, if you don't want to use them, the only option is chat, a book, or signs, but no one would use sign to catch user input

[young knoll]

Hypixel has entered the chat

[quaint mantle]

how do i use a sign?

if anvils won't work.

[lost matrix]

Anvils do work

[sterile token]

Yeah i mean with NMS, because by default api "you cant" do that

[quaint mantle]

how do i use it?

[thorn crypt]

Yo, how can I make a clickable text in books ?

[sterile token]

You are just doing a wrong implementation, most of the problems are caused 99% by us, devs

[quaint mantle]

I don't exactly know how, but I wouldn't recommend neither. Anvils are a pretty good choose.

https://www.spigotmc.org/threads/solved-open-sign-gui-get-input-from-player.380079/

what is the right implementation?

[young knoll]

Spigot doesn’t have api for components in books yet does it

[sterile token]

No, i dont think it has

[lost matrix]

Which of those items could be retrieved? The left or the right one?

[young knoll]

NMS or some third party API

[quaint mantle]

left.

wait

let me just launch minecraft.

[lost matrix]

Delay the close by one tick. I dont think you are allowed to close the Inventory in the click event

[young knoll]

You aren’t

Technically

[quaint mantle]

ok.

[sinful kiln]

You could use BetterInputs it allows for Anvil UI usage atleast on 1.16.5-1.19.3, just check for it on spigot

[quaint mantle]

I think 1 tick won't be enough, if it doesn't work, try directly with 5

Bukkit.getScheduler().runTaskLater(ChunkClaimsPlugin.getThisPlugin(), () -> {
                        player.closeInventory();
                    }, 1);```

[lost matrix]

This does not make sense. 1 tick delay is based on the handler being unregistered on close.

[young knoll]

Always kind of annoying to delay stuff by a tick

[quaint mantle]

Maybe, but I had problems delaying 1 tick to re open an inventory after being closed, I had to delay at least 10 ticks

[young knoll]

Gotta have your plugin instance :/

[weak meteor]

DAMNN THANKS

[lost matrix]

You should not close inventories if you want to open another one.
Just open the other inventory right away. It will simply replace the current
inventory (and not reset your cursor as well)

[quaint mantle]

huh, that seems to have fixed it.

[lost matrix]

Had a good guess then

[quaint mantle]

that was a guess?

[young knoll]

You aren’t meant to open an inventory directly in the click event either

[quaint mantle]

Not when the client closes the inventory

[lost matrix]

My guess was that the handler was being unregistered on close which prevented the click from being cancelled.

[sterile token]

Smile, something weird is happening, for some stupid reason the data published to global channel is correctly, but when publishing telling the receiver server, the JedisPubSub listener acts like if nothing wasnt received

[lost matrix]

Channel name mismatch

Print out the channel names for pub and sub

[quaint mantle]

Anyway, main problem fixed, yay!

[verbal slate]

Guys, how do I fix tabs in commands? When entering a command, it returns a list of arguments to me, but it is "static". Let's say it returns me a list of the words "apple", "orange", "lemon". And when I start typing "le", the list of hints does not shorten and hangs on the very first option.
In my case, this is a tab at the command /warp, I attach screenshots below

[quaint mantle]

https://imgur.com/vi7BTIi

anyway, how do i get the text from the textfield?

when the green glass pane is clicked.

[sterile token]

Im printing out the channel from JedisPubSub onMessage() and is seems not being called

[young knoll]

StringUtil.copyPartialMatches

[quaint mantle]

i just wanna get the text only if the green glass pane is clicked.

if that is possible.

[verbal slate]

Where should I apply it? Before return?

[lost matrix]

You are not handling your CompletableFuture exceptions

[young knoll]

Iirc you can return the result of the method directly

[sterile token]

right, thats true

I will handle them

[young knoll]

Since it returns a List<String>

[lost matrix]

  public CompletableFuture<Void> something() {
    return CompletableFuture.runAsync(() -> {
      // DO stuff
    }).whenComplete((result, throwable) -> {
      if(throwable != null) {
        throwable.printStackTrace();
      }
    });
  }

Example

[sterile token]

Right i should add to each publisher right?

[verbal slate]

okay, thank you

[lost matrix]

I usually append a handler for exceptions in my CF before i give them away so that i dont forget them.
So yeah, right when they are created.

Had too many cases with hidden exceptions 🥲

[sterile token]

okay now yes

😡 shity jedis pool

Thats causing the issues, its said me that it has the max jedis pool usage that he can use

[quaint mantle]

how did this person do that with the anvil GUI?

[lost matrix]

Bottom is the players inventory. Then he simply checks when the input field changes
and re-evaluates the content that is being viewed

[quaint mantle]

but how do i get the text?

how do i get this packet?

[lost matrix]

AnvilInventory#getRenameText()

[echo basalt]

welcome to futures

[quaint mantle]

how do i get the anvil inventory?

[echo basalt]

I made my own future class that just delegates to CF but doesn't hide exceptions

I call it FancyFuture

[quaint mantle]

i was not able to type cast the inventory object earlier.

[echo basalt]

it also has helper methods like thenSupply(newValue)

[young knoll]

✨Fancy✨Future

[echo basalt]

yea

[sterile token]

CF? Whats that weird slang

[echo basalt]

CF -> CompletableFuture

[quaint mantle]

nvm, i will just use chat probably for text input.

i am too tired at this point.

[sterile token]

oh bruh, you must write a book for those type of words, POO, CF, NPE

[young knoll]

ConversationAPI time

The api most people don’t even know about

[wet breach]

my favorite

[late sonnet]

please a book for how patch spigot xd

[wet breach]

finally

another thing I can point people to 😄

[young knoll]

Tbf I think it’s because it has minimal examples

[echo basalt]

I made my own conversation api

[young knoll]

It took a bit to figure out how to use it

[echo basalt]

I don't like spigot's that much

[wet breach]

my servertutorial plugin uses it

[echo basalt]

it just doesn't vibe with my code style

[wet breach]

and that is what I use to point to people for examples

[weak meteor]

@lost matrix, GUI manager is the one in charge for processing all the events, right?

[echo basalt]

Been working on a scripting system lately

it has like 20 different functions, not just the 2-3 shown in the sample

[young knoll]

Compiled or interpreted?

[echo basalt]

It's like

it gets "compiled"

well

[lost matrix]

The GUI manager doesnt have any logic in it. All it does is look at the map, check which inventory
was clicked and forward the events to the handler of those inventories. Each handler can now
decide for itself what to do with this event. The manager's only role is to transport events to where they are needed.

[echo basalt]

the text line gets converted to an object that looks like this

[weak meteor]

Hmm okay

[echo basalt]

To play, I just have a List<CompiledObjective> and each objective should call incrementStep to play the next queued objective

So for example, the wait 50 ticks method just calls incrementStep 50 ticks after

It's just something quick that I came up with in like an hour

[patent socket]

Ok so I applied and adapted this code, but now, when I run the command correctly, the task is not triggered, and it does not give me an error message. I tried putting code before and after running the task, and that code ran. DialogueCommand: https://paste.md-5.net/foduvubiko.java DialogueTask: https://paste.md-5.net/pukitizaro.java

[lost matrix]

wtf

Remove that method, (lol !?)

[weak meteor]

So the one that has logic in it is the Listener, and then in the Handler interface i code in it or where should i code the logic?

[verbal slate]

https://pastebin.com/raw/SwPTkAUJ These are not warps, but the essence is the same (my other plugin).

[young knoll]

Don’t pass the same list for both params

[lost matrix]

The listener doesnt need to be touched. The manager doesnt need to be touched.
All you need to do is:

• create an inventory
• create a class which implements InventoryHandler
• register this inventory with this handler
• open the inventory

[young knoll]

Pass an empty list for one of em

[verbal slate]

oh, okay

[weak meteor]

Okay

[lost matrix]

You will always only have 1 listener and 1 manager.
But you will have a lot of different InventoryHandlers (like shown in the diagram)

[verbal slate]

return StringUtil.copyPartialMatches(args[1], artifacts, Collections.emptyList()); that will be okay?

[weak meteor]

Yess

Thanks

Finally understood

[young knoll]

Probably not since Collections.emptyList will be immutable

[worldly ingot]

Yeah, pass a new ArrayList instance

Maybe give it an initial size if you have it

[patent socket]

But now the second task is underlined red in DialogueCommand? task.runTaskTimer(plugin, task, 4, 4);

[verbal slate]

Okay, guys

[lost matrix]

Ah yeah. You dont need that.

task.runTaskTimer(plugin, 4, 4);

[verbal slate]

It's work! Thank you much

[patent socket]

So all the errors are gone including that one, but it gives me An internal error occurred while attempting to preform this command.

[lost matrix]

Then solve the error

[patent socket]

There is none

[lost matrix]

Look in your console/log file. There is one

Nope thats not normal. This means you are giving too much time to the plugin

[lost matrix]

Are you running paper or spigot?

[hushed spindle]

are there any good methods to sort of benchmark how much bits of code are contributing to overall server lag? right now im just recording the system nanos and comparing it to various places in my code, but this seems to indicate accessing a simple map once takes 0.15ms which seems like a lot for such a simple action so i figured it must be coming from the logging process

[lost matrix]

MaxMillisPerTick: 22.5
AsyncChunkLoadingEnabled: true
HighAsyncPriority: false

[lost matrix]

Spark

[hushed spindle]

spark only shows the classes that are contributing to the lag, but i already know these classes
