[chrome beacon]

The Recipie book isn't an actual item

[candid galleon]

where are you creating it?

[quaint mantle]

cook

[chrome beacon]

Anyway that error comes from an invalid NBT tag

[quaint mantle]

no console error found

hmmm

[chrome beacon]

Why would there be one

The tag is invalid so the client has no idea what to do with it

[quaint mantle]

ahhh

[smoky oak]

the problem is probably in your initialization/setup of the book

[quaint mantle]

ahh Do you know which one(method) is related to nbt tag?

[chrome beacon]

So you don't know what your code does?

[quaint mantle]

yes I tried to find, but I don't know

what is related to nbt tag

[smoky oak]

It's where you set what the book displays the code you posted is fine

[chrome beacon]

Can you open your book in the first place without forcing it

[smoky oak]

the problem lies in a wrong setup of the book information, not the book opening itself

[quaint mantle]

hmm, it seems not 😦

when I give player a book, and open it, it doesn't have Invalid tag

[smoky oak]

maybe its a timing issue

if its like that i dont know what the issue could be, sorry

[quaint mantle]

its ok thanks you

[smoky oak]

If i might aska a question mysyelf...

did java -jar BuildTools.jar --rev 1.17 --generate-docs but i cant find the javadoc

[quaint mantle]

hmm

Anyone knows a way to get fully black player screen ? No potion effect 🙂

[smoky oak]

blindness x

ah wait

oops

[quaint mantle]

Yea it's for my hardcore plugin when player lost all lives. Would like to make it completely black

[smoky oak]

tell the player they're surrounded by black concrete

[opal juniper]

That would work ^^^

Send block change packets

So that they think they are surrounded

[quaint mantle]

Ah I'll look into that one thanks for that!

[opal juniper]

The only thing is that if they interact with the blocks they get removed - I think there is an event listener you can cancel though

[quaint mantle]

any example of config with saving all comments (custom)?

[quaint mantle]

Yea it's already been disabled no biggy :d

[opal juniper]

Just have the config.yml in the resources folder and then save it onEnable

[smoky oak]

back to my question where does buildtools.jar generate javadocs (I have the flag enabled?)

[quaint mantle]

but once I access the config the comments are out

[hybrid spoke]

you could do that with packets

[quaint mantle]

I save it -> access to store things from it -> comments kept only first header, not whole file, which is my issue

[opal juniper]

Which packet are you talking about

[hybrid spoke]

PacketPlayOutGameStateChange

[opal juniper]

Yeah, are you then talking about the sky colour one?

Or like the weather field

Or some shit like that

[hybrid spoke]

not sure which one he used https://www.youtube.com/watch?v=8kwbmozszY4

just googled and it was the first result

[opal juniper]

The problem I have had with that packet is that if you put a high number in it it gets unplayable

It gets really laggy

[opal juniper]

Looks like they are using the same packets

Oh he just triggered the game end screen

[hybrid spoke]

yeah obv. but idk what state he changed

[opal juniper]

Lmao

[hybrid spoke]

never did anything with this packet

[opal juniper]

He cut out the credits

From the video

But not the first like 0.5 seconds

[torn shuttle]

get set get set get set get set this is my life now

[opal juniper]

Ayyyyy

[torn shuttle]

just hundreds of files of getters and setters

[toxic mesa]

Those are rookie numbers, you should go for thousands of getter and setter files

[hybrid spoke]

ohhh i didn't watched the end lol

[opal juniper]

You can change the sky state which produces some nice effects

[torn shuttle]

well there's 729 class files in the project rn so I guess we're not that far off from thousands

[hybrid spoke]

who?

[quaint mantle]

any example of config with saving all comments and not keeping only first header (custom)?

[hybrid spoke]

you could use the PrintWriter to load your config from your resources

[quaint mantle]

and how to handle reading? because once I read from it, the problem is here again, lost comments

[hybrid spoke]

                PrintWriter pw = new PrintWriter(file);

                pw.print(IOUtils.toString(Objects.requireNonNull(Core.getInstance().getResource("messages.yml"))));
                pw.flush();
                pw.close();

its not reading. you print the received contents of the requested resource to the given file.

afterwards you flush it to close the stream so there will be no memory lying around

[quaint mantle]

yes, but I need to access things from it afterwards

and then the comments are lost again, once I do it

[hybrid spoke]

yeah so just get the FileConfiguration from the file

[quaint mantle]

will try, thanks

[native gale]

Hi, is there any simple way to open additional port to the server, let's say, 127.0.0.1:1111, and be able to determine, if the player joined via main port 127.0.0.1:25565 or 127.0.0.1:1111?

[hybrid spoke]

https://www.spigotmc.org/threads/listen-on-multiple-ports.44375/

[native gale]

Eh, thank for the link, but it isn't particularly what I meant. I was talking about Spigot plugin, where the behaviour will depend on the port the user uses to connect.

And I was wondering if there's a way to handle this using Bukkit/Spigot API only

[hybrid spoke]

you have to state your needs clearly

[native gale]

Sorry, English isn't my first language

It was difficult to even state them as I did

[hybrid spoke]

you could use the PlayerLoginEvent and check for the hostname

[grizzled bear]

Hello,
Is someone knows how to use Maven Shade Plugin with Eclipse, it's my first time and I look a few dozen of forum discussions, but I still have the same exception on my plugin: ClassNotFoundException
I give my pom.xml file: https://pastebin.com/ygi6HNnM
thank you in advance 🙂

[eternal night]

?paste

[undone axle]

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

[eternal night]

please

delete the code block and paste the link

[grizzled bear]

Sorry, but this website isn't working

[eternal night]

oh damn, it is actually down 😱

[grizzled bear]

Can I use pastebin ?

[eternal night]

yea

any bin website is good, just pasting huge codeblocks is clearing every other problem from the chat

[grizzled bear]

Yes I understand, sorry for the inconvenience

Here is my pastebin: https://pastebin.com/ygi6HNnM

[eternal night]

Hmm why are you depending on yourself tho ? What class is not found when running ?

[grizzled bear]

I've created an API that give an access to my databases so I use on my plugin many classes to get some datas from tables. Classes are GeneralPlayer and CharacterInformations, there are each used to access to a table

[eternal night]

oh, right I see your artifact is called mmoDatasaved

your groupId is wrong btw

<groupId>mmoDatasaved</groupId>
<artifactId>mmoDatasaved</artifactId>

[quaint mantle]

👀

[grizzled bear]

It's my plugin so I need to use my package for the groupId ?

[eternal night]

Yea, similar to what you did for mmoDatabase

fr.MrUrica I guess

[grizzled bear]

Oh ok, I'll try it

[eternal night]

can you paste the output of your mvn package run ? the maven shade plugin seems fine to me, so the log should show more

[grizzled bear]

I installed it only on my eclipse IDE 😦

[eternal night]

but doesn't eclipse also show the logs ?

you are compiling using maven right ?

[grizzled bear]

No, I compile like another plugin (JAR file)

[eternal night]

well then obviously your maven configuration isn't going to get you anywhere 😅

[grizzled bear]

Has I understand, when I compile like another plugin, I already checked maven files so it compiles with
Maybe a version problem

[eternal night]

I am not sure that eclipse actually uses maven under the hood to compile your plugin

[cold field]

Does anyone know why with the InventoryClickEvent when I change the itemMeta of the "currentItem" it works only in survival or also in creative if I delay the task by 1 tick?

[grizzled bear]

My plugin is running on my server, only with ClassNotFoundException exceptions, and I used spigot in maven dependencies. I think if Java had compiled without maven, the plugin didn't load on my server

[quaint mantle]

are you saying it doesn't work in creative?

[eternal night]

do you have maven installed ?

[cold field]

It works if I delay the instruction by 1 tick

[grizzled bear]

Only on my Eclipse IDE

[quaint mantle]

creative is clientside

[eternal night]

https://stackoverflow.com/questions/14896152/how-to-build-and-run-maven-projects-after-importing-into-eclipse-ide

try to run it as a maven build

[cold field]

Hem, what? Are you sure? If I delay by 1 tick it works as it should

[quaint mantle]

#help-development message

[cold field]

So this guy is right

But idk why If I delay by 1 tick it works

[grizzled bear]

I have a build failure: No goals have been specified for this build.

[eternal night]

you are missing package as a goal

[grizzled bear]

It works, but I think I used a wrong compiler plugin version: Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.5:compile

[eternal night]

I think the newest would be 3.8.1 ?

[grizzled bear]

Yes sounds good, the build was completed, I'll try this jar file

[cold field]

Ok, I get it, creative is client side but why it works only if I delay?

[grizzled bear]

Haha, it's a bad joke I think, but my console tells that my plugin.yml is invalid 😦

[eternal night]

sounds like an easy fix tho

[grizzled bear]

Probably

Jar does not contain plugin.yml 👀 what ?

[eternal night]

where is your plugin.yml

better be in the resource folder

[grizzled bear]

ohhh, I put it in the same root as src folder

[eternal night]

it goes in src/main/resources

[grizzled bear]

like src/fr/MrUrica/mmoDatasaved/resources ?

[eternal night]

oh

you aren't even following maven project structure

did you just throw in a pom.xml ? xD

[grizzled bear]

I converted my project into a maven project, then I edited pom.xml but I didn't change anything else 😅

[eternal night]

yeah maven projects have a set layout you gotta follow

https://github.com/jenkins-docs/simple-java-maven-app

an example maven repo

[grizzled bear]

ok so I have to put before my package a main folder

[eternal night]

yea basically goes src/main/java/my/package/name

[grizzled bear]

Okay then, I create a src/main/resources

Again an error on compilation: Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile

Don't I need to edit this line on my pom.xml ? <sourceDirectory>src</sourceDirectory>

Ok, I changed my sourceDirectory to src.main and the plugin works !
Thank you @eternal night

how tf did i miss that

ty

[loud island]

should stuff in a DatabaseHandler class be static?

[eternal night]

not really a reason to

[ivory sleet]

No

[loud island]

ty

[ivory sleet]

Of course this depends more exactly on how you’re designing it but when it comes to storage types you probably want to take advantage of polymorphism and abstraction which static isn’t the best at.

[loud island]

im not making anything complicated

the most complicated thing I need rn is just checking whether something exists in a mongo collection lol

[eternal night]

An interface abstraction might still be pretty useful for you

[last harbor]

String code = "public class Test {"
                + "    public static met() {"
                + "        System.out.println(\"hi\");"
                + "    }"
                + "}";```
I'm trying to compile this string
And to have access to run the method from anywhere
Does anyone know a way to do that?

[eternal night]

I think compiler API is only part of the oracle JDK iirc

so you are probably fucked

[noble spire]

Does Bukkit#BanList#addBan work for offline players?

(It takes the username rather than the UUID)

[eternal night]

https://stackoverflow.com/questions/2946338/how-do-i-programmatically-compile-and-instantiate-a-java-class

[dire marsh]

you can use a uuid too I think

[noble spire]

Then I'd expect it to take a UUID object

[dire marsh]

¯_(ツ)_/¯

try it

[noble spire]

okay

[dire marsh]

Bans by name are no longer supported and this method will return null when trying to request them. The replacement is bans by UUID.

it seems if you provide username it will just use their uuid

[wraith rapids]

imagine if the documentation actually described what form 'target' is in

[tardy delta]

does this returns the args with a space between them?

public static String getFinalArg(String[] args) {
        StringBuilder message = new StringBuilder();
        for (String arg : args) {
            message.append(arg).append(" ");
        }
        return message.toString();
    }

[quaint mantle]

Is there GoatBumpBlock event?

1.17 of course

[quaint mantle]

or something like this

[hybrid spoke]

yes it do

[hardy swan]

And a space after

[tardy delta]

ok

[eternal oxide]

why loop when you can just return String.join(" ", args);

No trailing space

[tardy delta]

does that also work for an array?

[eternal oxide]

args is an array, do you mean a List?

[tardy delta]

nah i meant does that return the args with a space between them? thats what i need

[eternal oxide]

yes

[tardy delta]

oh lemme try then

but how can i remove the lore from an item?

i did meta.setLore(null);

[tame coral]

Once you modified the meta of the item, you need to set the item's meta to the new ItemMeta object you modified

(don't know if it's clear lol)

[tardy delta]

yea i know

its just that question ^^

[tame coral]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/inventory/ItemStack.html#setItemMeta(org.bukkit.inventory.meta.ItemMeta)

should work now

[tardy delta]

ah ok

thanks

[tame coral]

[smoky finch]

Is there a way to show multiple tab complete options for a command, but prevent players from being able to use them?

Like when they press tab and it copies the text into their chatbox.

[frosty tinsel]

No

[eternal oxide]

anything you put in the list will be shown on the client. Whether they can use that option is up to your command code.

[tame coral]

How to you add tab complete options ?

Is it in plugin.yml that i need to add something ?

[eternal oxide]

no, in code in teh tabcompleter method

[smoky finch]

No, it's just that I don't want them to be able to automatically use them from the box rather than manually typing it themselves

[frosty tinsel]

You have to set tabCompleter class the same as you do CommandExecutor

[eternal oxide]

You choose what they can see in the tab complete by building the list

[tame coral]

like extend the class ?

[smoky finch]

I'm trying to colorize tab completes for showing error messages and colorized info in general, but it kicks the player if they tab complete that message and send it

[frosty tinsel]

Implement, yes

[tame coral]

Okay, thanks

[frosty tinsel]

Look at some tutorial

[tame coral]

Don't worry i'll figure it out

The docs are good enough

[eternal oxide]

public class BaseCommand implements TabExecutor

[frosty tinsel]

Yeah, the TabExecutor is better

[eternal oxide]

that does both CommandExecutor and TabCompleter

[tame coral]

Okay thanks

[eternal oxide]

If you add it to the tab completer they can try and use it

[zealous hill]

hey, I use for my plugin Ageable ageable = (Ageable) b.getBlockData(); on Sweet Berries and Glow Berries (1.17), for the Sweet Berries it works, but for the glow berries they are not ageable, how can i get if they are grown or not ?

[eternal oxide]

If the block is a Cave vine it can grow berries

Its not ageable as its a random chance for growing a berry

[ivory sleet]

Like a vine

[eternal oxide]

well, it is actually agable, but the age does not affect when/if it has fruit

[zealous hill]

Okay but how can I check if the player is harvesting a grown glow berry (if it has fruit) ?

[tame coral]

PlayerInteractEvent ?

[eternal oxide]

I would guess watch teh PlayerHarvestBlockEvent

[noble spire]

Is there an easy way to turn a java https://docs.oracle.com/javase/8/docs/api/java/awt/Color.html into a the closest https://hub.spigotmc.org/javadocs/spigot/org/bukkit/ChatColor.html ?

(Or just specify an rgb value for a ChatColor)

[tame coral]

For chatcolor there's only the specified color available

But I guess you can try to add an if close with the hex tag to find the closest one

I don't know if there's any easier way to do this

[noble spire]

hmm okay I'll keep searching

[tame coral]

good luck

[eternal oxide]

^ using vectors and shortest distance is the only way really.

[noble spire]

I mean does this support rgb? https://minecraft.fandom.com/wiki/Formatting_codes

[eternal oxide]

https://www.spigotmc.org/threads/how-to-get-a-chat-colour-code-from-a-raw-colour.355557/

[tame coral]

actual maths, damn

[noble spire]

actual maths be like

[tame coral]

yeah but still

i hate vectors

[noble spire]

Launches Unity3D

[eternal oxide]

If books support json then yes

[summer scroll]

There is a libs from like 2013 to get closest ChatColor from Color.

[eternal oxide]

https://www.spigotmc.org/threads/getting-setting-written-book-json.309808/

[eternal oxide]

we found out thats not what he actually wants

So yes you can use rgb colors in books but only using unsafe

to access the json

[noble spire]

Yeah, but I'm not talking about books 😔

[eternal oxide]

Eff man, you just showed us a BOOK and asked for that

[noble spire]

that's just a preview

it's what ChatColor's constants are

[eternal oxide]

ask yoru ACTAUAL question, not around the bloody houses

[noble spire]

right?

[eternal oxide]

ask an actual question. As we have answered every one you asked and you keep telling us thats not it

[wraith rapids]

bukkit does have an implementation for a rgb supporting § colorcode, but it is super gay and nobody uses it

various plugins have their own implementations

[ivory sleet]

§x§F§F§F§F§F§F NNY?

Tomasan don’t use that command in this channel thx

[frosty tinsel]

Sorry

[noble spire]

Is that a thing?

[frosty tinsel]

Where can I find all the commands?

[ivory sleet]

Well with the help command but use something like #spigotcraft for it I guess

Or #text maybe

[ivory sleet]

Yes that color code is a thing but idk why mojang decided to use that

I think at least

[noble spire]

I mean: https://www.spigotmc.org/threads/full-rgb-chat-color-support-in-1-16-snapshot.432828/ would be nice, but we're not there yet ig

When premium plugins are approved do they get listed right away?

[cold tartan]

im not sure why my bossbar isn't working (it just is completely empty every tick until i update then the next tick it is empty again), this is the code that is updating the bossbar:

bar.setProgress(val/max);
``` is there something wrong with that?

do i need to do that every tick?

btw val is a num between 0 and 120, and max is 120

do i need to like round that to the nearest 100th?

cuz sometimes i can get numbers like 8.(3 repeating)

[hybrid spoke]

you'll be notified and the plugin will be listed under premium resources, yes

[summer scroll]

Sometimes you need to be patient too xd, I've been waiting for almost 2 weeks and haven't got approved yet.

[hybrid spoke]

if you just update it once it will just update once.

[cold tartan]

yeah but for some reason it doesnt stay

[hybrid spoke]

show us the code

[cold tartan]

ok

[hybrid spoke]

doesn't also bossbars have a cooldown

and vanish afterwards

[quaint mantle]

Ok so Im trying to check if the location in the configuration file equals to the location of the STONE_BUTTON clicked in the PlayerInteract event with this: https://paste.md-5.net/ecazuwipig.cs

[wraith rapids]

use equals

== doesn't do what you think it does

[quaint mantle]

I tried equals as well, doesnt work

[hybrid spoke]

== checks if the adress of the object in the heap are the same so the vars are refering to the same object or not

there u go @hybrid spoke sorry about that i forget aobut paste.md a lot

[dusk flicker]

I doubt it would be .name, considering it seems to be an enum you prob need to pass it in a method

[hybrid spoke]

and what exactly isnt working? where is your scheduler setting the val every time?

[dusk flicker]

?jd

[undone axle]

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

BungeeCord Chat: https://javadoc.io/doc/net.md-5/bungeecord-chat/latest/index.html

[hybrid spoke]

this doesn't return anything than the enum itself

you need to get the value by that enum with the #getStatisticmethod

[dusk flicker]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/OfflinePlayer.html#getStatistic(org.bukkit.Statistic)

[cold tartan]

the scheduler runs every second and is in the main class

[tardy delta]

so like this

meta.setDisplayName(p.getStatistic(Statistic.PLAYER_KILLS) + " kills");

[cold tartan]

also what isn't working is that the tick after i set it it just goes back to empty, the val stays it just displays empty

[hybrid spoke]

most likely

[quaint mantle]

Location{world=CraftWorld{name=Skylands},x=-166.0,y=131.0,z=95.0,pitch=0.0,yaw=0.0} is what loc returns and this is how it looks in the config:

Skylands:
  traitorTester:
    testerButton:
      ==: org.bukkit.Location
      world: Skylands
      x: -166.0
      y: 131.0

so something with your calculation is wrong

[cold tartan]

OH WAIT

AHHHHH

INTEGER DIVISION

mmmmmmmmmmmmmmmmmmmmmmmmmmmm

that might be it

[tardy delta]

yay it works

[hybrid spoke]

and what if you don't create the location right out of config? you could create a new location object by yourself with getting the values from the config

[cold tartan]

there we go! it works! tysm!

[hybrid spoke]

np^^

[quaint mantle]

I tried doing this: https://pastebin.com/iFddBjFN (the get map thing returns Skylands)

[hybrid spoke]

uhm. you are getting the configuration section

not the value

ah wait nvm

pastebin is just eyecancer

why do you have different casings?

[quaint mantle]

for the traitorTester?

yeha already saw that and fixed it but wasnt the issue

yea it is * everyone but when i try its null

[wraith rapids]

what is null

[proud basin]

Yea what Mr Skull Head said

[hybrid spoke]

mr chaplin

[tardy delta]

i have something that checks is the argument is valid and it says * is null

[wraith rapids]

context

we have no idea what you are talking about

[hybrid spoke]

maybe because you check for a player and "*" is not online?

* is *, not null

[tardy delta]

yes

[hybrid spoke]

and you wonder why its null?

[dusty sphinx]

How can I get an Advancement from it's key?

nah it looks for the player called * or something

yeah

what is he returning if he cant find a player named *?

But when I do System.out.println(mapManager.getMap()); it prints out the world name correctly? Why would world be null then?

uh, I'm trying to install the remapped mojang jar and I keep getting this error when using --remapped

does anyone know how 2 fix this?

Cancel InventoryClickEvent works fine

[vague cypress]

Yes, but what do you use to cancel the click event? I tried using title and it didn't work

[quaint mantle]

event.cancelled

[vague cypress]

I have

            event.setCancelled(true);```
but it doesn't work

[ivory sleet]

I use InventoryHolder but arguably InventoryView is better

[vague cypress]

I do have an inventoryHolder, how would I use it to cancel an inventory click event?

hey, im wondering how to edit block type without editing the direction/shape, i want to edit stair/slab types (from stone_brick to end_stone) without changing their shape. how do you do that? whenever i use block.setType() it also sets the shape

[quaint mantle]

Hi, I'm developing a simple economy plugin. Each player has a file to define their balance.

[cold tartan]

uhhhhh, prob wanna do a json file rather than a file for every player

[quaint mantle]

So I developed a richer server system. It pulls all files to make a list, over time it would get heavy?

[unreal quartz]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/material/Directional.html#setFacingDirection(org.bukkit.block.BlockFace)

[quaint mantle]

i'm using yml

[cold tartan]

ok but a file for every player is a lot

[unreal quartz]

it's fine

[cold tartan]

how would i use that?

[quaint mantle]

What do you recommend?

[vast sapphire]

    @EventHandler
    public void onAppleEat(PlayerInteractEvent event) {
        Action action = event.getAction();
        Player player = event.getPlayer();
        if (action.equals(Action.RIGHT_CLICK_AIR) || action.equals(Action.RIGHT_CLICK_BLOCK)) {
            if (event.getItem().equals(ItemManager.invertedApple())) {
                if (event.getItem() != null) {
                    player.addPotionEffect(new PotionEffect(PotionEffectType.ABSORPTION, 600, 5));
                }
            }
        }

    }``` Why am i not getting the potion effect applied?

[unreal quartz]

sent thr wrong one

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/block/data/Directional.html

that's what you want

the other one is deprecated

[vast sapphire]

ItemManager.invertedApple()``` is a public itemstack

[vast sapphire]

for this

[cold tartan]

json:

{
  "balances": {
    "USERNAME1": {
      "amount": 20
    },
    "USERNAME2": {
      "amount": 102947
    }
  }
}

[unreal quartz]

seems pointless to have another map after username

[quaint mantle]

How would I go about generating a rank based on values?

I currently use this.

[hardy swan]

maybe he wanted to store other information like transaction history or sth idk

[cold tartan]

im not entirely sure how to use json in java (im used to py), but i know that many plugins use it so you could probably find how online

[cold tartan]

in case u need more info

[vague cypress]

This doesn't work for some reason...

        Player player = (Player) event.getWhoClicked();

        if (event.getInventory().getHolder() instanceof menuGUI) {
            event.setCancelled(true);
        }

    }

[unreal quartz]

not sure what other info you would need except a number under "balances"

[hardy swan]

but it does make sense design wise

[cold tartan]

like a max bal

[unreal quartz]

i would keep transactions under a separate key

[hardy swan]

different economy balances

[tardy delta]

Did your menuGui extend InventoryHolder? Or implements idk

[quaint mantle]

Files per player?

[vague cypress]

menuGUI impliments InventoryHolder

[unreal quartz]

ideally i would do that

or.. use an actual database designed for this stuff

[hardy swan]

ideally sql db lol

[quaint mantle]

I don't know how to use sql db

[hardy swan]

hmm... learn?

[unreal quartz]

then learn

[hardy swan]

can start from sqlite, the easiest & serverless one

[unreal quartz]

this is exactly what sql is for

[quaint mantle]

Oh ok

[hardy swan]

is menuGUI an instance or a class?

[quaint mantle]

I'm going to look for some tutorials on spigot

[hardy swan]

if former, instanceof isn't correct, if latter, your naming isn't correct

[unreal quartz]

whatever you do i wouldnt keep all playerdata in a single file unless you plan on reading the entire thing into memory one time

[vague cypress]

A class I believe

[hardy swan]

then your naming isn't correct

MenuGUI, PascalCase

[cold tartan]

ok, i got it working for stairs, but how would i for stuff like slabs or walls?

[vague cypress]

Yeah, menuGUI is a public class. Do I just have to change the name?

[unreal quartz]

might be this https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/block/data/Bisected.html

[hardy swan]

It is a convention for java classes to be in PascalCase

[unreal quartz]

actually no this for fences https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/block/data/MultipleFacing.html

/ walls

[hardy swan]

although, it then shouldn't be the cause of the problem

[hardy swan]

interestingly I have seen Towny done otherwise

[unreal quartz]

don't really know anything about towny

but it generally doesn't sound like a good idea if you're gonna have a shit ton of playerdata

because you're going to be reading and writing to that single file constantly and you're going to have a nightmare synchronising it if you don't want to lock up the main thread

[hardy swan]

yea i understand, just stating what I observed lol

maybe it is a rabbit hole

[loud island]

So I'm attempting to use https://github.com/lucko/commodore, and CommodoreProvider#isSupported seems to be returning false even after following all the steps to implement it

[hardy swan]

have you tried opening up or search through the issues?

[loud island]

I'll take a look

[hardy swan]

when you say implement it, what do you mean

[loud island]

use it in my plugin

[hardy swan]

then returning false is a sign that it is implemented

else it would throw classnotfound

[loud island]

It should be returning true, if it's false Commodore can't work

The problem is Brigadier not being supported for some reason as far as I can tell

I haven't found any issues related to this in the github repo

[hardy swan]

hm you can consider opening an issue regarding that

[loud island]

I asked in the lucko discord, if nobody is able to help there I'll open an issue

ty for trying to help tho :)

[hardy swan]

yea... it is weird

[quaint mantle]

How can I create the player in the database?

[unreal quartz]

insert into if not exists

also you should lookup how to use prepared stmts properly

[dusk flicker]

Also a note it may be good to make that a util to execute querys so you do not re type everything every time.

[hardy swan]

in most situations you dun even need to create the player

[dusk flicker]

And also you should store it by uuid not by name

[torn shuttle]

world#getWorldType is deprecated, what replaced it?

[dusk flicker]

You seem to be trying to do something that you don't have enough experience to do.

[torn shuttle]

@wraith rapids yeah that's it thanks

[hardy swan]

why need check if player has account?

if it is to check before creating an account, then the "account creation" might not even be needed

[quaint mantle]

i`m using this tutorial

https://www.spigotmc.org/threads/how-to-sqlite.56847/

Do you think it is necessary to check?

[unreal quartz]

doesn't look like a how-to, but more like "here's a shit ton of code for you to shove into your plugin with no explanation"

[hardy swan]

the tutorial didn't say anything about checking

but

it did mention replace

REPLACE INTO inserts if not already exists in sqlite

[loud island]

don't copy-paste code unless you actually understand what you're doing, it'll just lead to you having headaches later

[dusk flicker]

^^ that's a huge thing, as your code could be heavily improved with a better understanding

[hardy swan]

I would say otherwise tho 🤔 to copy first then understand it. Cuz you can mess with it and find out what it actually does

[loud island]

copying is ok as long as you understand what it does

i'm definitely not saying don't copy, but it's worthless if you fail to understand what you're actually copying

all you end up learning then is how to press ctrl+c and ctrl+v repeatedly

[earnest sonnet]

yes

[hardy swan]

Yea definitely must understand it nonetheless

[quaint mantle]

Having an hard choice here, need to freeze player, currently I disable movement which is crap due to looking like massive lagg, what would be an better option ? Was thinking to teleport player each x ticks but think that would not be to great of an option either, anyone got an better way to handle player freeze ?

[opal juniper]

Cancel the move event

It’s the only way

You cannot tell the client it can’t move

[unreal quartz]

just teleport them to the centre of the block if they leave the block if you don't want it to look too laggy

or stick them on an arrow and don't let them dismount it

[hardy swan]

What is that thing whereby slab bugs the hell up players and traps them in place

[quaint mantle]

Never heard of that one before :p

[unreal quartz]

woudl probably work

Hi when i tryin' send post request to api i have an error i don't know why

[unreal quartz]

whatever library you're depending on is not shaded

[agile anvil]

Hi there,
I'm just getting into the 1.17 and I already have a issue. Here is the context: I used to spawn an ArmorStand using nms in 1.16.5 (and lower). So I tried just to "translate" all the class to the new mapping. Result: no error but armorstands are not spawning.
Is there anything new in the involved packets?

[hardy swan]

Nms yes, package changed

[agile anvil]

Yep I noticed, so I moved all the class, but it doesn't work

[hardy swan]

Any snippets?

Are you doing it in server/exposed thread?

[agile anvil]

How do I spawn an armorstand?

1. Create EntityArmorStand instance with parameters: CraftWorld, x, y, z
2. Invoke setInvisible(true) to the instance
3. Invoke setCustomNameVisible(true) to the instance
4. Invoke setMarker(true) to the instance
5. Invoke setCustomName(IChatBaseComponent) to the instance
6. Send PacketPlayOutSpawnEntityLivingConstructor(instance)
7. Send PacketPlayOutEntityMetadataConstructor(getdataWatcher)

Sorry but the code is horrible so here is the step I do ^^

[agile anvil]

I'm in the server thread

[hardy swan]

I believe you dun have to spawn armor stand this way

In fact no need nms at all

There is a method in World

[agile anvil]

I'm doing a plugin which is compatible with 1.8-1.17 and which require to use NMS with reflection

[hardy swan]

Even the spawning part?

[quaint mantle]

Does anyone have a good sqlite tutorial?

I want to implement a local database in my economy plugin

[agile anvil]

Especially the spawning part because it's an ArmorStand visible by only one player

[hardy swan]

https://www.sqlitetutorial.net/ for sqlite
but you will need to look for jdbc docs for implementing in java too

[hardy swan]

Ohhhh

[torn shuttle]

the official sqlite docs are p good

[hardy swan]

Then i dont know lol, weird to have no error

[agile anvil]

Yep 😢 Thanks anyway! I'll try to figure it out

[cold field]

Guys just wondering, is it possible create a new file inside a jar or is it blocked for security purpose?

[agile anvil]

Create while running ? Like storing data inside the jar?

[cold field]

Yes

[eternal oxide]

no

You store data in a database or in files in teh plugins data folder

[torn shuttle]

actually yes you can write into a jar file

maybe you shouldn't, but you can

I have a new hobby and it's giving emotional support to people who ask for support and provide literally no details

the great thing about my hobby is that I get to do it for 4 hours every day

[cold field]

I was just wondering on how an updater of a java application works. I'm not talking about the plugin that you put the jar inside the update folder and spigot take care. What I don't get is how the java application is able to replace itself with the updated one

[torn shuttle]

it doesn't, not really

it creates a new copy and self-destructs

but since the end result is seamless you end up with a ship of theseus or a teleportation philosophical question

[cold field]

Is it able to delete itself?

[eternal oxide]

theres two ways to do it

[torn shuttle]

pretty sure it's possible yeah

hell back in the day I believe it was myth 2 that had an uninstaller which uninstalled your entire OS

the good old days of gaming

I still have that sucker installed somewhere

[eternal oxide]

you either execute an updater which then replaces teh original, or it places teh new one in an update location. Then next startup it copies anything from teh update location to teh new

When you execute a "Launcher" its just a wrapper that checks for a new version, replaces the old version and then executes it.

[cold field]

That was what I was thinking to do. And that is because I asked if I can save stuff inside my jar

Thank you

[shrewd solstice]

is this correct????

public List<String> onTabComplete(CommandSender sender, Command cmd, String label, String[] args) {

Y'all know how to connect my discord bot to my minecraft plugin ?

like could y'all give me the method for getting the jda variable

cuz when I try doing Bot.jda= JDABuilder.createDefault(Bot.botToken).build();

it says java.lang.NoClassDefFoundError: net/dv8tion/jda/core/JDABuilder

[unreal quartz]

shade jda

though you should be aware that jda is massive and you won't be able to post it to spigot

[quaint mantle]

yes It's a private plugin

but how does discordsrv work then?

[unreal quartz]

by releasing on github

[quaint mantle]

i see

so what about shade jda?

how shall I do that

[unreal quartz]

depends what you're using to build the plugin

[quaint mantle]

I'm exporting the jar to my plugins folder

[unreal quartz]

then add the contents of the jda jar to your own

how you do that with your ide is something you're gonna google yourself

[quaint mantle]

I've downloaded jda

[unreal quartz]

i gathered

[quaint mantle]

I've added the build path to the plugin

like I did with spigot

so im not sure why thats wrong

[unreal quartz]

because that is only available at compile time

at run time spigot is provided (for obvious reasons), but jda is not

so to fix that, you shade it in yourself

[quaint mantle]

how may I "provide" it to the plugin

[unreal quartz]

and once again how you do that depends on your build system and unfortunately i can't read your mind

[quaint mantle]

https://gyazo.com/279bf8cd91635fc15deb0aa5144f2048

there

a screenshot

[unreal quartz]

i don't use eclipse so i have no idea

i am sure a simple google search will solve your issue

[quaint mantle]

all I've seen so far are tutorials for how to shade a jar file using a maven project

but my project isn't maven

so

help?

[unreal quartz]

might be time to learn maven, but i have no idea how to use eclipse sorry maybe someone else does

[unreal quartz]

you probably tried to insert a duplicate key into your table

[quaint mantle]

So every project I make I should make it a maven project?

[unreal quartz]

if you want to use maven

[quaint mantle]

but is that the only way to shade a jar?

[shrewd solstice]

how to put the players to completion????

[quaint mantle]

cuz every tutorial I've seen uses maven

[unreal quartz]

well at some point you'll eventually use a build system like maven

[wraith rapids]

there are alternatives to maven that perform the same functions

maven is just popular in the bukkit ecosystem

[quaint mantle]

ok so there's no way to use maven to shade a jar into my plugin for my existing project ?

I have to make a new maven project?

[unreal quartz]

maven has a file called pom.xml which contains details about the project, you add one of those to your project and you have a maven project

[quaint mantle]

that's all I have to do to shade ?

a jar

[shrewd solstice]

@silver cove how to put the players to completion????

[quaint mantle]

what?

[shrewd solstice]

like /hat set PLAYER

[steady saddle]

tab completion

[shrewd solstice]

yes

[unreal quartz]

you literally don't need to do anything to add player tab completion

the server does that by default

[shrewd solstice]

x) ok

Guys how kick player in RedisBungee i need help.

I think you wanna use sendProxyCommand assuming you have a kick plugin installed on your bungee proxies

[royal hawk]

No kick not installed in proxy :c

Oh yeah well then use the sendData

Google plugin message channels or something

You should probably find a wiki page

So, I tried to use this to stop people from removing items from my custom GUI, and it's telling me expression expected on "Inventory". Why doesn't this work?

    }```

[wraith rapids]

Inventory is a class

you need an object

[shrewd solstice]

no :/

it juste set nothing

change args.length > 0 to args.length == 1

            }
        }
        inv.setResult(result);
    }```
 the crafting works but when i fill all 9 slots with compressAmethyst() i get 1 compressAmethyst()?

[shrewd solstice]

yes i know and i do it x) but...

[keen kelp]

Bukkit#EnablePlugin gives the error
Enabled plugin with unregistered PluginClassLoader PluginName PluginVersion

[frosty tinsel]

Press TAB

[shrewd solstice]

yes i do and nothing

[frosty tinsel]

It maybe overridden by your plugin

[shrewd solstice]

maybe???

[ivory sleet]

Send entire error

[keen kelp]

there is no more

there's no stacktrace

That's it

[twin venture]

so i was searching for 3 weeks now ..

and no one here helpful enought to answer me ..

[ivory sleet]

@keen kelp are you using plugman or doing something else which isn’t normal

[ivory sleet]

I have literally no clue what your actual issue is, but be patient

[keen kelp]

I just wrote my own thing

        PluginManager pluginManager = Bukkit.getPluginManager();
        Plugin game = pluginManager.getPlugin("Game");

        if(pluginManager.isPluginEnabled("Game"))
        {
            pluginManager.disablePlugin(game);
        }
        pluginManager.enablePlugin(game);

That's it

[ivory sleet]

Is this within your game plugin?

[keen kelp]

No

This is an external pluign

a plugin can't restart itself ._.

[ivory sleet]

Not true but ok

[keen kelp]

Since it can't run code to enable a plugin when it's disabled

runnable?

[ivory sleet]

You can do some extremely hacky stuff to self restart

[keen kelp]

Yeah but no thanks :D

[ivory sleet]

Anyways need to eat ttyl

[keen kelp]

I would figure there is a hacky way

ttyl?

oh talk to you later

thx google

[weary pagoda]

Italy wins everything

[frosty tinsel]

Read the rules, if it isn't there, then you probably can

[agile anvil]

@hardy swan Just for information I found the issue (about NMS) : The problem was during the packet sending, I use reflection to fetch sendPacket method but the "playerConnection" stuff was also changed... So I finally succeed !

[frosty tinsel]

Best feeling

[earnest sonnet]

I've seen developers printing the consoles messages like that, probably it's safe

[frosty tinsel]

I think so as well

[eternal oxide]

Its frowned upon. It can be classed as advertising which is not permitted

[unreal quartz]

paperlib provides a method which does exactly that, i'm fairly certain that it was already agreed on that it was allowed

[wraith rapids]

it's only frowned upon by those who don't know better

[eternal oxide]

paperlib isn't distributed on the spigot platform

[wraith rapids]

namely the majority of spigot's userbase

people not knowing better is literally the last thing keeping spigot going

well, that and people getting banned for no reason from the paper discord and refusing to use it out of spite

cc tan juck

[smoky oak]

quick question quick answer, is the saveConfig() function working even if the directory Plugins/<Pluginname here> is not yet created?

[wraith rapids]

it'll most likely throw a file not found exception

[eternal oxide]

I know saveDefaultConfig creates the directory. No idea on just save

[smoky oak]

wait i have a ide just look up the function

[wraith rapids]

imagine not developing with ms notepad and javac

my keyboard only has 2 buttons

a 1 and a 0

[eternal oxide]

abacus or bust

[smoky oak]

Better than running it on a mechanical computer

err

correction, just slightly worse

[wraith rapids]

i use small stones instead of pen and paper

[smoky oak]

https://xkcd.com/505

[earnest sonnet]

That's 100% true

[smoky oak]

I have no idea if you're referring to me or not

[wraith rapids]

i will eventually build myself a pneumatic computer

it's probably going to sound great

[smoky oak]

Oh try to rebuild the gear computer! Might be a good stepping stone to calculate how to preassurize everything

[wraith rapids]

gears are more annoying to work with than pneumatic tubes

tubes are kind of like wiring, just thicker

[smoky oak]

...i just realized i just thought 'steampunk' and had the completely wrong idea lol

what about a water powered computer tho?

we already have the logic gates for that

[wraith rapids]

water is kind of messy and corrodes components

the thing with air is that it's easily available and disposable

no need to route everything back into a tank

[smoky oak]

eh true

btw do you plan to work with overpreassurized or underpreassurized air?

[wraith rapids]

the advantage of hydraulics is that liquids don't compress, so you get accurate and strong movement

but neither of those are really necessary i wouldn't think

overpressurized is better as vacuum pumps are slow and the tubes would probably collapse and get stuck

[smoky oak]

i see. maybe hydraulics would be a good idea to shift what the main bus is connected to atm?

[wraith rapids]

perhaps

[vast sapphire]

Bump, need help on this one

[wraith rapids]

though, i really don't look forward to hydraulics

i need to deal with hydraulics just enough irl

it's cancer

everything needs to be perfectly sealed and withstand high pressures

it's like being a plumber but on steroids

[opal juniper]

hydraulics are cringe

[smoky oak]

ouch, but how else to shift the bus?

[wraith rapids]

air pressure will probably be enough

[smoky oak]

Good luck with your ram tho

[wraith rapids]

yeah pneumatics will be slower

but it's not like I'm going after speed anyway

[smoky oak]

no how do you want to address stuff?

[frosty tinsel]

This is excellent 😂😂

[wraith rapids]

i'll either look at some schematics of some simple old chips or just come up with something on my own

probably the latter

[smoky oak]

I think intels 4004 is a good starting point

[wraith rapids]

i'd write that down but I'll probably forget about having written it down before I get around to doing it

[smoky oak]

eh just remember it's the first fully functional cpu

@dry meadow is that the actual code in your onEnable() ?

[dry meadow]

yes this is in my onEnable()

[smoky oak]

can u pm me your plugin.yml?

[opal juniper]

why pm?

just

put it here

[smoky oak]

eh fair i just dont want a big file here cluttering things up

[opal juniper]

?paste

[undone axle]

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

[opal juniper]

lmao

[smoky oak]

or that

[opal juniper]

Is the issue that the first command does not get registered?

[frosty tinsel]

In your main do getDescription().getVersion()

Rather

[dry meadow]

  name: TempPlugin
  main: io.github.tempplugin.TempPlugin
  author: Temp
  description: Temp
  version: 1.3.2
  commands:
    cmda:
      description: cmda
    cmdb:
      description: cmdb
    cmdc:
      description: cmdc

[frosty tinsel]

To get your plugin's version

[smoky oak]

okay that makes no sense. Your commands should still show up in the /help but shouldn't be executable

[opal juniper]

If the if statement is false i see no reason why they should run

[digital plinth]

ohh what si that

[digital plinth]

????????

does that work?

that plugin.yml

[opal juniper]

why wouldnt it

[dry meadow]

Yes it works

[dry meadow]

It's not the plugin version...

[opal juniper]

although - you should specify the api-version

[frosty tinsel]

Ok

[opal juniper]

so that your plugin is not in backwards compatibility hell

[dry meadow]

I should note, that the actual version should be for a 1.8 server for my friend. So i haven't added the api-version

[opal juniper]

oh ok

[wraith rapids]

and so, the list grows

[opal juniper]

[tall ridge]

xd

[digital plinth]

arrows lose custom model data when they are shot and picked up

is there a way around it

[opal juniper]

I mean it would be a pain

you would have to track it from ItemStack -> Entity -> ItemStack

Idrk if there are enough event listeners for that

lemme have a look

[lunar wedge]

file = new File(Bukkit.getServer().getPluginManager().getPlugin("PureMail").getDataFolder(),"lang.yml");

        if(!file.exists()) {
            try{
                file.createNewFile();
            } catch(IOException e){
                //owww
            }
        }```

This is throwing an error
```[13:43:49 ERROR]: Error occurred while enabling PureHomes v1.0-SNAPSHOT (Is it up to date?)
java.lang.NullPointerException: Cannot invoke "org.bukkit.plugin.Plugin.getDataFolder()" because the return value of "org.bukkit.plugin.PluginManager.getPlugin(String)" is null```

[opal juniper]

Do not use getPlugin

is PureMail the plugin you are making?

[lunar wedge]

Yeah

[opal juniper]

is this the main class?

[digital plinth]

on projectile hit, save the location of the arrow entity, give the player a custom arrow when picked up

also is it possible to make a shapeless recipe with a item with custom model data

[lunar wedge]

wow nevermind im an idiot

im making PureHomes not PureMail lol

its resolved

[opal juniper]

Dont do it this way though

[lunar wedge]

thanks for pointing that out it would have taken me an hour to figure that out

[digital plinth]

.addItem(Material)

[opal juniper]

you should use the plugin instance

[lunar wedge]

Oh whats a better way to do it?

[digital plinth]

not itemstack

[lunar wedge]

ohh

[digital plinth]

:<

[opal juniper]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/entity/ProjectileHitEvent.html
Store a reference to the EID or something from this^^
https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/player/PlayerPickupArrowEvent.html
Then listen to this ^^

Make sense?

[frosty tinsel]

Just do getDataFolder()

[opal juniper]

I wouldn't use the location cause that is not a super persistent way of doing it

[opal juniper]

they may not be in a class that extends JavaPlugin so this is not great advice

[frosty tinsel]

Yeah I know, but it is easier for me to make them try that, than to explain them what a main class is

[opal juniper]

eh

[frosty tinsel]

Do you know what is main class?

[tall ridge]

I name my main class Main

[opal juniper]

Ew

[frosty tinsel]

Yeah, I started doing that recently as well

[wraith rapids]

Main should be reserved for the application's bootstrap and main class

[tall ridge]

then the class extends JavaPlugin

[keen kelp]

How do I make the output/build jar to just be
PluginName.jar
instead of
PluginName-vPluginVersion.jar

[opal juniper]

maven?

[wraith rapids]

and your plugin is not an application; it's a plug-in

[keen kelp]

gradle

[opal juniper]

oh idk

[wraith rapids]

your plugin's main class is the class that represents your plugin

and as names should be descriptive, your main class name should probably take after your plugin

[unreal quartz]

https://docs.gradle.org/current/dsl/org.gradle.api.tasks.bundling.Jar.html

gradle have good docs

you should read them

[keen kelp]

k thax

wait but Im not running jar?

Im running build

[digital plinth]

yea

oh niceeeeeeee discord bot you've got here

[unreal quartz]

build runs jar

[keen kelp]

oh ok

[digital plinth]

how 2 make a shapeless recipe with a item with custom model data

[keen kelp]

you cant iirc

extract item is only for shaped

[wraith rapids]

use ExactChoice

pretty sure shapeless recipes still let you use ExactChoice over MateriaChoice

[keen kelp]

Oh really

cool

[digital plinth]

thx

[rotund pond]

Hello !
Have you ever made a GUI manager system?
I am trying to make a proper one but I have no idea how to do it .. I would like, if possible, to have examples

[opal juniper]

what does

GUI manager system
mean

[digital plinth]

google.com

plenty of examples

[frosty tinsel]

Look at one from Kody Simpsons

[rotund pond]

Mmh...
Something to manager your GUI from your plugins
Create, use etc ...

[frosty tinsel]

I've made my own based on Kody Simpsons's YT channel

[rotund pond]

Ty, i'm gonna look at this

[keen kelp]

is there a better way to get main other than DI?

[wraith rapids]

depends on your definition of better

[keen kelp]

I mean if I can not use it at all...

Also another thing, is there a way to get another Plugin's file name?

[dusk flicker]

What do you mean file name? Like the jar?

[keen kelp]

Yes

[dusk flicker]

I doubt there is a method for it, you may be able to scan the plugins directory but not sure how easy it'd be to get a plugin name from that

[keen kelp]

in their main you can do getFile()

But how do I do that with only a Plugin

[dusk flicker]

I'm not sure if that, others may. For your DI thing, if you can't use DI that may mean you need to use a singleton, or you need to rework your objects to use DI in some way

[keen kelp]

Ill look into that later

but first how get other plugin file

[dusk flicker]

Is it for any plugin or a specific one

[vast sapphire]

how do i play a sound when the player crafts something

[keen kelp]

well the purpose of it is for a specific

But I would like it to work with any

I dont want to hard-code it

especially file names

[dusk flicker]

Yeah I can't help you with that then, my only idea was to hard code it

[keen kelp]

imma hard code it for now... How do I get the plugins directory

[dusk flicker]

Only other idea I could think of but no clue if it exists is looping through all plugins and try to get their main class, if you can pass it through the I think it's JavaPlugin#getPlugin https://hub.spigotmc.org/javadocs/spigot/org/bukkit/plugin/java/JavaPlugin.html#getPlugin(java.lang.Class) and get that with a Class.forName I believe and then get the file with the method

[keen kelp]

That gets you a Plugin right

I still dont get a File

[dusk flicker]

It gets you their main class

Then you could use that method getFile you said

[keen kelp]

But I can't do getFile

[dusk flicker]

Why can't you?

[keen kelp]

It's protected

protected getFile()

[dusk flicker]

Oh damn

https://stackoverflow.com/questions/735230/java-reflection-access-protected-field

Check that out

That's the only way I could think of doing it

[keen kelp]

i dont even know what it's doing

maybe it's because it's 6:30

[dusk flicker]

Honestly don't know why that's protected

Maybe a PR making it public would be accepted but who knows

[keen kelp]

tbh the post you send is probably an exploit/security concern and most likely already got patched

I didn't look into it

I just think so

since protected means the only way to use it is to extend it

[dusk flicker]

It's reflection so doubtful

[keen kelp]

yeah my brain is turning into brain soup

it's melting

I gotta sleep

bye

[rotund pond]

Still using Kody Simpsons's ways?
I just looked at its code and there are a lot of mistakes in my opinion...
Already, there is no object-oriented code (too bad for Java), no division of tasks and, must of all, no protection:

Not everyone knows this, but there are some hacked clients who can dupe the names of inventories (or even add § signs) to get inventories of the same type as these, so these players can use them to bypass your plugin. To avoid this, I personally add the player to a list when I open the inventory to them and remove them from the list when the inventory closes. So I know who is authorized to use the GUI.

By the way, the things he shows in his videos, I already know them ...
I'm looking for something much more sofficial, which allows to manage GUIs in a very clean way with object oriented code.

[vague cypress]

Alright, so I have the below code trying to make a menu. Near the bottom is code trying to lock the menu items from being removed. I'm not sure what to put after event.getInventory() != to reference the custom inventory, or if I'm doing it entirely wrong.

    @EventHandler
    public void onPlayerClicks(PlayerInteractEvent event) {
        Player player = event.getPlayer();
        Action action = event.getAction();

        if (action.equals(Action.RIGHT_CLICK_AIR) || action.equals(Action.RIGHT_CLICK_BLOCK)) {
            if (player.getItemInHand().getType() == Material.NETHER_STAR) {

                Inventory inventory;

                inventory = Bukkit.createInventory(new menuGUI("Menu"), 9, "Menu");
                ItemStack item = new ItemStack(Material.PAPER);
                ItemMeta meta = item.getItemMeta();

                //Paper
                meta.setDisplayName("§f§lWelcome Message!");
                List<String> lore = new ArrayList<String>();
                item.setItemMeta(meta);
                inventory.setItem(0, item);

                //Diamond
                item.setType(Material.DIAMOND_BLOCK);
                meta.setDisplayName("§1§lShop");
                item.setItemMeta(meta);
                inventory.setItem(1, item);

                player.openInventory(inventory);

            }
        }

    }

    public void onClick(InventoryClickEvent event) {

        if(event.getInventory() != ) return;

        event.setCancelled(true);

    }```

[vague cypress]

Thanks!

I do have one more question - How would I go about only opening the inventory if the object that was right-clicked with had a certain custom model data? I already have the below in place:

            if (player.getItemInHand().getType() == Material.NETHER_STAR) {

[quaint mantle]

How do you add a custom patch to Spigot?

[sage swift]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/inventory/meta/ItemMeta.html#getCustomModelData()

[quaint mantle]

or rather, where do I find instructions for it?

nevermind, just found this awesome forum post https://www.spigotmc.org/threads/tutorial-adding-custom-patches-to-spigot.158694/

[vague cypress]

Thanks again! Really sorry, but where would I implement that in what I have? I tried a couple of things but they didn't work.

[sage swift]

get the item meta

also you should probably do a null/air check before getting type or the like, as the player could be holding nothing

[vague cypress]

Wait sorry, is there a way to check for specific custom model data rather than just having custom model data in general?

[sage swift]

#help-development message

[quaint mantle]

is the code the same for adding an item to a players inventory the same as for the latest version

[vague cypress]

It appears that when I try to use any of the three custom model data-related methods and put an integer into the parameter, it says that it can't be applied to type int

[sage swift]

what "three methods" are you trying

do you want to set it, or check for a certain value?

[vague cypress]

I want to check if the item has a specific custom model data

[sage swift]

and you are putting a specific number into the method

[vague cypress]

But not if it has custom model data in general, but if it has a specific number combination as the custom model data

Yes

            preparedStatement3.setString(1, this.getConfig().getString("db.prefix") + "worlds");
            preparedStatement3.execute();```

setString isn't the right method

how i can stop the giant head moving (it only happend when its spawn)
teleport(pitch) didnt work tho

[digital plinth]

head?

[dusty sphinx]

How would I get rid of all a player's advancement progresses?

[weak mauve]

yep

[dusty sphinx]

I ended up doing that, I sure hope nobody sets db.prefix to ; DROP TABLE worlds; --

[haughty musk]

Hi. I am trying to make a teams system and it doesnt seem to work

Maybe because I have another scoreboard running at the same time?

[digital plinth]

ohh that head movement

well why bother its not too bad

also i dunno how 2 fix it

[weak mauve]

they spin

[digital plinth]

rather

they snap

[reef wind]

maybe tell us what is not working?

[haughty musk]

Sorry. The teams arent showing when I hit tab or when i check for teams with /teammsg

No code errors

Just wondering if everything in the code looks ok

And where you guys would recommend I call the function

(I currently have it in onJoin)

[dusty sphinx]

How would I do this? Would I need to iterate through all advancements and remove advancementprogress this way?
