i cant even use System.out.println

[ivory sleet]

yeah

[tardy delta]

show error

[ivory sleet]

needs to be within a scope

[tardy delta]

i wanted to say that >_<

https://i-own-a.blacklisted.store/j5UFzNFA

[ivory sleet]

your ide isnt broken

you just cant put System.out.println() everywhere

[urban kernel]

...

[ivory sleet]

or well at least not where you put it, so where did you put it?

[urban kernel]

package me.deveroonie.discord.commands/Discord.java (class)

[ivory sleet]

no

which line

share the class

?paste

[undone axle]

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

[tardy delta]

just drop a screen lol

[urban kernel]

package me.deveroonie.discord.commands;

import org.bukkit.configuration.file.FileConfiguration;


public class Discord {
    private final FileConfiguration config;

    public Discord(FileConfiguration config) {
        this.config = config;
    }


    System.out.println(config.getString("discordLink"));
}

[ivory sleet]

yeah exactly

in this case you might just wanna move the sysout to inside the constructor scope

[urban kernel]

dont give a shit about the sysout

it'll be removed anyway

[eternal oxide]

that code will not even compile

[urban kernel]

package me.deveroonie.discord.commands;

import org.bukkit.configuration.file.FileConfiguration;


public class Discord {
    private final FileConfiguration config;

    public Discord(FileConfiguration config) {
        System.out.println(config.getString("discordLink"));
        this.config = config;
    }

    
}

this looks like it will work, it isnt throwing dreaded red line

[ivory sleet]

under the this.config = config;

                }
                break;
            ```🥴

[tardy delta]

aaaa

use a for loop

[eternal oxide]

This code will throw a NullPointerException. Reverse teh two lines in your constructor as Conclure said

[tardy delta]

isnt it gettin the config passed as parameter?

[urban kernel]

package me.deveroonie.discord.commands;

public class Discord {
    private final FileConfiguration config;

    public Discord(FileConfiguration config) {

        System.out.println(config.getString("discordLink"));
    }

[tardy delta]

yes

[sacred prairie]

are you able to teleport an armorstand while someone is riding it with stand.teleport(loc);

[fringe frost]

Guys, I need to do a votifier plugin. But i dont know how they (server lists) send the data. Do anyone know?

[urban kernel]

have a server list send data to a test server ig

[tardy delta]

what does ig mean

[urban kernel]

i guess

[echo basalt]

No

[sacred prairie]

is there any other way to set the posistion of this armorstand, or should i just use an other mob instead

[flint coyote]

You can't teleport entities with passengers. But you can dismount the passenger, tp both and remount

or you move it with velocity

[small current]

guys if i send a forward message through bungee messaging channel to ALL server
will it be sent to the sender too ?

[ornate heart]

I've got a skull head item stack with custom texture.

How would I place that down instead of creating an item?

[sacred prairie]

you have to try this out

[restive tangle]

Is there a pair data type in Java? I made an enchantItem() method which takes (ItemStack, EnchantData...) where EnchantData is a data class I made specifically for storing the Enchantment and an integer value

[crimson terrace]

you mean a HashMap or something of the likes?

[lusty cipher]

Does Files.move block until the file is properly moved?

Every second time one of my files is deleted when I try swapping them

                    Files.move(backupFile.toPath(), temporarySwapFile.toPath());
                    Files.move(nbtFile.getFile().toPath(), backupFile.toPath());
                    Files.move(temporarySwapFile.toPath(), nbtFile.getFile().toPath());

[quaint mantle]

how can i spawn a silverfish and make them only have one target that they are able to hit?

[crimson terrace]

if you dont wanna use nms I suggest using the EntityTargetEvent

and cancel the event for any targets except the one you wanna allow

[quaint mantle]

thanks

but i'm making an ability so it spawns like a few silverfish and multiple players can use the ability at once, soo how is that gonna work

[crimson terrace]

edit each silverfish on their PDC. maybe make a namespacedKey which has the players UUID in string form

and then you can check that data and decide whether you want it to be targeted

[eternal oxide]

you put the ownign players UUID into the entities PDC. Then in any target event you check for an owning player and cancel if its the owner

[quaint mantle]

what is PDC

[noble forge]

Is it possible to force a blockstate client-side? I am currently trying to force the distance blockstate on leaves without any luck

[restive tangle]

Not really, I want to do

enchantItem(
  item,
  new EnchantData(Enchantment.SHARPNESS, 2),
  new ...
)

[crimson terrace]

do a forEach

and pass in a list of EnchantData

alternatively to get closer to what you want, pass in an array and you can put the EnchantData objects into {} as a parameter I believe

[restive tangle]

I already do that, I'm asking if there is a better way

[crimson terrace]

is it not good enough?

you could do it with a stream but its unnecessary in this case imo

[restive tangle]

It's alright, just thought it was weird to create a class for a pair

[noble forge]

had the same thing

weird how java doesnt have a builtin tuple type or pair type

[restive tangle]

True

[crimson terrace]

records are the closest thing we have to that atm i believe

[noble forge]

eh

those are more like structs I would say tho

[quaint mantle]

how do i get the X amount of stone in a player's inv

[crimson terrace]

how you get the amount of stone a player has in their inv?

[quaint mantle]

ye

[crimson terrace]

loop through the inventory and add all the amounts of itemStacks which are stone together

[quaint mantle]

if i have an event and i have multiple if statements in it, if i add return; at the first one, it won't go through the rest?

[rotund pond]

Hello !
I'm looking for an event where an entity die, so I can get the entity and the killer ...
What's the event ? I'm using the EntityDeathEvent but I can't get the killer 😦

[crimson terrace]

if a return is called the method is basically cancelled

[rotund pond]

NVM, i'm dumb

[crimson terrace]

EntityDeathEvent

it works

[rotund pond]

Yeah, I though it was something like event.getKiller but it was event.getEntity().getKiller() xd

[crimson terrace]

just be aware that the killer may not exist if the entity was not damaged by any players

[rotund pond]

Oh well, just understood that a killer is always a player

What if a snowman kills a zombie so ?

(That's an example)

[crimson terrace]

if the entity which dies was never damaged by a player the Killer will be null I believe

[rotund pond]

Okay I see, ty

[humble tulip]

maybe listen to entitydamangebyentityevent

[rotund pond]

nice idea

ty guys

[humble tulip]

check if the damage will kill the entity and make sure its not cancelled

probably have your priority at highest

[rotund pond]

You're right

[rotund pond]

Lowest you mean ?

[humble tulip]

highest

lowest is run first

[rotund pond]

Ah yes mb

[humble tulip]

EntityDamageByEntityEvent you mean?

[rotund pond]

Actually I can use EntityDeathEvent, it's all good to me because I need a Player killer ^^
I was just curious, but ty

[crimson terrace]

the Killer is always set to the Player who last hit the entity. If it dies by a block or falldamage the killer is still that player that hit it down the cliff or so

in case that helps

[rotund pond]

Ty 👍

[rustic pewter]

Hi, I have a question. I am a complete newbie to minecraft plugin development and fairly new to Java. I have followed a few lessons. I followed a tutorial for event-listeners but it wont recognise. See screenshot: https://imgur.com/a/Ragvwgz

[noble forge]

I dont think thats really how you make a listener

Usually you would make a separate class that implements the listener interface along with an eventhandler method

[eternal oxide]

Listener

[toxic phoenix]

try typing capital L

[noble forge]

its really bad practice to do it in the main class tho no?

[eternal oxide]

depends on teh size of the plugin

[rustic pewter]

Oh I dont know. The capital L did work Thanks!

I am just trying it out. 🙂

[rustic pewter]

Another problem 🙃 I am getting this: [20:20:26 WARN]: Nag author(s): '[Ruubbie]' of 'BestPluginEverMade' about their usage of System.out/err.print. Please use your plugin's logger instead (JavaPlugin#getLogger). error when running this: ```@EventHandler
public void onPlayerJoin(){

    Bukkit.broadcastMessage("A player joined the server welcome them!");

}``` piece of code.

[civic dagger]

so how can i get the entity that damaged other entity in EntityDamageEvent? i found ENTITY_ATTACK and ENTITY_SWEEP_ATTACK and some other damage causes that i want to keep track of but idk how to get the entity that actually damaged them

[noble forge]

I am pretty sure it's actually this what is causing the warning

System.out.println("Plugin enabled!")

[rustic pewter]

Oh, thats also verry possible.

Then my broadcast doesnt work

[noble forge]

wrong event

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/entity/EntityDamageByEntityEvent.html

[civic dagger]

lmao i just had to look for other similar events...
thanks :D

[noble forge]

use getDamager() to get the attacker

[vestal dome]

is there a way to set the color of a wool, on bukkit?

(1.7 btw 😂)

u forgor?

1.7

not 1.17

[eternal oxide]

Wool color in 1.7 is the data/damage value

[noble forge]

before 1.13 color was a blockstate

[vestal dome]

which it is a big no no for bukkit bc NMS is simpler, and doesn't use that.

(on 1.8+)

[vestal dome]

btw asked this because maybe NMS has some type of enum with the colors and their data values & stuff

dunno

[eternal oxide]

line 46 onwards either delay 1 tick using the scheduler, or cancel the click event

[stray flare]

Tried, im getting full of errors such as plugin cannot be null

[quaint mantle]

So currently i have an issue where when i do the spawn command the first time it tps me too spawn if i wait 5 minutes then do it again it pulls this

[undone axle]

Guide to dependency injection: https://www.spigotmc.org/wiki/using-dependency-injection/

[quaint mantle]

ucant find a find the fix as i cant see no errors anywhere

[eternal oxide]

constructor should be public

[vestal dome]

or

protected if on the same package.

[stray flare]

alright and

Main = https://pastebin.com/pje8GGfk

[eternal oxide]

thats all, just pass your instance when you create teh listener

new Summon(this)

[stray flare]

The constructor Summon() is undefined

[eternal oxide]

summon(this)

[stray flare]

` @Override
public void onEnable(){

    getServer().getPluginManager().registerEvents(new Summon(), this);
    new Summon(this);
}

@Override
public void onDisable(){
    
}

}`

[dusk flicker]

please for the love of god use three of `

[stray flare]

okay sorry

[eternal oxide]

getServer().getPluginManager().registerEvents(new Summon(this), this);

[stray flare]

Thank you im gonna test it

Works perfect. thank you very much @eternal oxide

[ancient plank]

imagine not escaping your backticks !!! ```

[dusk flicker]

Hey !

Is there an easy way to check if a block mined is a crop ?
I mean, another thing than

Material blockMaterial = event.getBlock().getType();

if(blockMaterial == Material.CARROT || ...)
  return;

Just change his drop on death

What's the question exactly ?

[golden turret]

if i create a listener and a class that extends it, will the listeners from the parent be registered too?

[noble forge]

How can I prevent a block from ticking?

I want to prevent the pp update of leaves

[tall dragon]

you want to stop the decay?

[noble forge]

leaves calculate and update their blockstate distance to the nearest log

I want to prevent them from updating their blockstate distance

[tall dragon]

because?

[noble forge]

because I want to use them for custom (translucent) blocks

[tall dragon]

so you want to stop them decaying then.

[noble forge]

no

distance is in a range of 1-7

you can assign a custom model to each blockstate

[tall dragon]

ah

i see where ur going with that

[noble forge]

if I reimplement the decay logic with a plugin and use 1 blockstate I free up 6

however

when I set the blockstate it just returns back to its original value rn

[tall dragon]

im not rlly aware of a way to stop blocks from ticking

[noble forge]

I couldnt really find anything on the forums either

[tall dragon]

you could look into BlockPhysicsEvent but im not sure you can use that eiher in the way you want.

[noble forge]

im not sure if that fires tho

[tall dragon]

yh no idea either

[noble forge]

I will test

At least u have given me a path to go onto

thank you

[tall dragon]

?stash

[undone axle]

https://hub.spigotmc.org/stash/

[tall dragon]

else you might benefit from just looking into mc code how they are being ticked & see if its possible to do somethn with reflection.

[noble forge]

yeah that was my 2nd idea

I already downloaded the build tools

but lets hope this works first

thank u either way!

[tall dragon]

👍

[noble forge]

It seems I may have struck gold as my pc is burning down and my terminal is filling up with numbers I'd like to see

[sacred prairie]

How do i teleport/move an armor stands wich has a passanger?

[noble forge]

true life saver

catching the event worked

thank you again!

[rotund pond]

If anyone knows ^^'
Crop class is deprecated

[noble forge]

what I did for leaves was just have a set of all the leaf types and check if the current material was inside of that set

[rotund pond]

Oh I didn't know about this block data, ty

[civic dagger]

why EntityInteractEvent is not triggering? i tried player interact event and it worked perfectly now i just replaced it with entity and its not even triggering

or is it for something else?

no

trigger a event when a skeleton tries to shoot with a bow

or similar things

this works for players

also not when shoots

when tries to shoot

in another saying i want to block it

[potent quest]

other than the standard block place/break/destroy & player interact events, is there any other events i should listen for and run location based checks for an antigrief?

[noble forge]

what would be the best way to change the blocktype of newly generated trees? Preferably I want to add on logic/code when a tree is generating its leaves. Would anyone know to point me in the right direction please?

[tall dragon]

prettu sure you can use this for that https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/world/ChunkPopulateEvent.html

when it comes to trees being generated from sapplings. you can use StructureGrowEvent

[noble forge]

oo I see

and is there any more performant way of setting blocks other than setType?

[tall dragon]

if that doesnt help. you can also make a custom tree generator i believe

[noble forge]

I see

[tall dragon]

there is yes

[noble forge]

thank you. I will check if using this event is performant enough for me and otherwise will use custom tree gen

[tall dragon]

take a look at this https://www.spigotmc.org/threads/how-to-set-blocks-incredibly-fast.476097/

[noble forge]

thank you will take a look

I am processing multiple chunks and setting blocks in each of those most of the time and I was wondering if doing it multithreaded would improve anything?

[tall dragon]

uh u can only change blocks from the main thread tho

you could probably divide the load tho. and proccess over time.

[noble forge]

oo

so instead of multithreaded, async?

[pulsar vessel]

can any devs volenteer to help me with this problem
i need it fixed quick
pls dm me

[glass mauve]

dontasktoask

[tall dragon]

nah. i mean you could devide the load. like if you have a task instead of doing it in one tick do it in 5

[noble forge]

oo I see

[tall dragon]

thats how i make big block operations lagg free at least

[noble forge]

wait so how does async work then?

[tall dragon]

u cant change blocks async

[noble forge]

I mean doing the processing part

[unkempt peak]

Send the problem don't ask if you can

[pulsar vessel]

dm

[noble forge]

I was thinking perhaps I could process it all async and then add to a queue and then on main thread go through the queue

[unkempt peak]

Why?

[noble forge]

or would that be worse for performance?

[glass mauve]

just ask your question here

[tall dragon]

you should read this article. it explains it very nicely https://www.spigotmc.org/threads/guide-on-workload-distribution-or-how-to-handle-heavy-splittable-tasks.409003/

[noble forge]

thank you! Youve probably noticed already but im a bit inexperienced 😅

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.

Better question: Who writes a method stub with one argument like that?

public void setPlayerScoreboard(
            Player p
    ) {

[quaint mantle]

there were more

but i cleaned it

good that u mentioned it

The thing is, it sets it when a player join, but then, doesn't change it.

[lost matrix]

Did you make sure the method is actually called?
Add a sysout at the beginning of the method and see when its being called.

[quaint mantle]

Yeap.

no idea why it doesn't work

[shut field]

I still have no clue what to do

[lost matrix]

Do you want to use CraftBukkit or NMS with maven in 1.17+

[shut field]

Craft

[lost matrix]

https://www.spigotmc.org/threads/9-years-of-spigotmc-spigot-bungeecord-1-18-1-18-2-release.534760/

Scroll down to "Developer Notes" and then read the "NMS" section

[shut field]

so is this saying that I can still use the 1.17 stuff?

[wary harness]

anyone could tell me is this bad approach

[shut field]

I'm just trying to access CraftPlayer but it says that this class doesn't exist

so I think that I need to import smth, using maven or depending on it? and even after reading this I still don't know how to

[last sleet]

Is serializing data (like custom enchantments) into PDC's with, strings, for example better or should I make a plugin file that records item stacks and associates enchantments with them

[waxen plinth]

My only real question is why you're putting a blank line between every single line of code

[wary harness]

I got problem with reading when lines are to close

so I need some spacing

[vale cradle]

It's fine and respectable but I'd rather just increase the spacing in the IDE settings, that way it will help you read other one's code

and help other ones read yours more comfortable ;P

[wary harness]

will look in to that thanks

[vale cradle]

To the main question, what are you trying to do?

[wary harness]

So I am spawning mobs with PDC from custom spawner.
Now question is about performance is it good idea to check does entity has specific PDC key on every single damage event?

Other idea would be to add UUID of entities to HashSet

on there spawn

[vale cradle]

If you're already using PDC why don't keep using it then?

[wary harness]

Concerned with performance on EntityDameEvent

[wary harness]

This

[eternal night]

I mean PDC is rather close to a plain hashmap

[vale cradle]

I actually don't know how different the PDC API is compared to the NBTApi, but I don't think there would be hardly any noticeable different so you're probably fine with either

[eternal night]

you have a bit of overhead

[wary harness]

?

[vale cradle]

One is a HashMap the other one is Reflection based and I believe it has to constantly parse the NBT string back and forth

[eternal night]

^^ PDC basically converts to nbt when you call set

no IO or anything but object conversion

[vale cradle]

They're basically the same, I'd say one has a higher Memory footprint while the other one is more CPU intensive

I think you're fine with either tbh

[wary harness]

well I will try it out this way then will see on live server will there be any laggs

Thanks for info

[vale cradle]

If you see any lag, I don't think it's related to using PDC API or NBTApi, imo ;P

[tepid ore]

How do I make a pattern that has a certain start and end string but unknown mids? Like this <<Hello>> and <<Something>> are valid as they start with << and end with >>

[vale cradle]

You mean regex pattern?

[tepid ore]

Yeah

I know you can do this [a-fA-F0-9]{6} but I have no clue of how to set the characters to an unknown amount

[vale cradle]

<<(\w+)>>

[vale cradle]

you can use {1,} or + which is the same but abbreviated

[tepid ore]

Omg I'm stupid, I tried googling it but for some unknown reason my brain thought a matcher and a pattern is the same. Which I know they are not lol

[tepid ore]

Ahh, I see. Thank you!

[vale cradle]

you can always go to a regex tester, they are very helpful

https://regex101.com/ for example

[tepid ore]

That is very helpful indeed, thanks!

[waxen plinth]

^<<.*>>$

[tepid ore]

Thanks 🙂 I think Imma stick with <<(\w+)>> tho, as it's easier to read imo :>

[waxen plinth]

They are different

[vale cradle]

^^

the other one takes all of the characters, including whitespaces

[waxen plinth]

That one will only match alphanumeric characters + underscore

Mine accepts all characters

[vale cradle]

\w is closer to this

[waxen plinth]

Mine also will only work if the << is at the beginning of the string and the >> is at the end

[vale cradle]

I also just realize you used from a to f

[tepid ore]

Hmm, yeah. Forgot that lol, I only really use latin chars, digits and underscores so \w is fine. I found this really useful, https://docs.oracle.com/javase/7/docs/api/java/util/regex/Pattern.html.

Doesn't <<(\w+)>> require << and >> at the start and end tho?

[waxen plinth]

It will match anything surrounded by those

So abc <<something>> def would match

But only the middle part there

If you want it to have to be the entire string you need ^$

[tepid ore]

Ahh, I see. I only use it for placeholder-ish type of stuff. So it should be allowed anywhere in a string

[waxen plinth]

Alright

[tepid ore]

Really good to know though

[humble tulip]

https://www.spigotmc.org/wiki/bukkit-bungee-plugin-messaging-channel/#forward
I am reading through this wiki page, specifically the Forward section. I want to know if i NEED to specify a subchannel. I would like my plugin to communicate with other servers with the same "server name" which is set in the config. so i registered the outgoing and incoming channels as pluginname_servername. I feel as though this is better than just registering the channel as pluginname and having a subchannel for servername as messages will only be sent where they need to go to

thoughts^?

[ivory sleet]

I mean it’s probably for the best if you write a sub channel

Assuming you use the default channel

Else it’s pretty much not needed

[humble tulip]

" so i registered the outgoing and incoming channels as pluginname_servername"

i registered my own channel

[ivory sleet]

Yeah you probably don’t need a specific sub channel, but like it’s convenient for let’s say format identification

[lethal python]

i saw someone on a forum say they could send players custom notifications using the tip gui, like the one which tells you you have new crafting recipes i think

how do you do that with spigot, i couldn't find anything in the docs

https://www.spigotmc.org/threads/narrator.493165/

Here is the post where someone declares they can send notifications using the tips window, but they don't provide any proof of it

[ivory flume]

What's good practice when saving an inventory to a database like mysql

whats a good way to do it

[wet breach]

you could serialize it and then store it as a blob

how you choose to serialize is up to you, I recommend just serializing to binary though

then you can just unserialize easily

[crisp steeple]

yeah, only minor problem is that it makes a web api for viewing inventories pretty much impossible

its surprisingly difficult to serialize any other way though besides yml (or binary), which yml isnt really supported to save to sql

[wet breach]

it doesn't make it impossible

[crisp steeple]

how?

i wasnt able to find any good way of doing it

[humble tulip]

I'm having a problem with plugin messaging. I've set it up as shown in the Wiki but it doesnt seem to work.

[wet breach]

because php is capable of deserializing the information? just because you use a different language doesn't mean you can't deserialize the same way you serialized

[humble tulip]

omg

i wanna put a new line

[crisp steeple]

storing to binary using the bukkitobjectoutputstream, it cant deserialze it without having a server running or else the itemfactory breaks

[wet breach]

wasn't talking about using bukkit methods to serialize

but you can implement the bukkit method into php easily though

[crisp steeple]

well i was using java

i was storing it in a database as binary with bukkitobjectoutputstream, tried using json but it wasnt able to deserialze on the server

im not too sure what other way to deserialize a bukkitobjectoutputstream would be, seeing as it uses methods that require a minecraft server being run

[humble tulip]

see how the methods work internally and reimplement it

[crisp steeple]

it uses configurationserializable, the problem is will deserialize it to an item, and making an itemstack without a server running causes many issues

[wet breach]

you don't need to use bukkit methods to serialize

especially the way I am talking about

[crisp steeple]

which way are you talking about?

im not sure what other way there would be to serialize to binary without using object output streams

[wet breach]

don't serialize the object

just serialize the data

[crisp steeple]

?

its very difficult to serialize the data of an item

[dusk flicker]

not really

[crisp steeple]

what way do you have?

[dusk flicker]

most of them are strings, just pass it through json

it will take time to do it manually but not that much time

[crisp steeple]

but theres item nbt as well

[dusk flicker]

well how is that stored

"having data" isnt the issue, its how its stored

[crisp steeple]

its stored in a json-like format, but using something like gson doesnt work for storing the nbt tag

[dusk flicker]

you can EASILY put data from Java to json or other stuff

[crisp steeple]

ik

i tried serializing the nbt of an item to json, however youll get problems when you try to deserialize it because it doesnt know the type of the nbt compound

[dusk flicker]

I feel like you are spending more times making excuses on why it wont work rather than figuring out how it will work

[crisp steeple]

spent a couple hours working on it over here 🙃

you can read through the messages if you want more detail on the things i tried

still never resolved the issue, finding a solution would be great

heres the wrapper class i tried making as well, still never worked though because of how the item meta works https://paste.md-5.net/famikeroxi.java

[round agate]

make a custom deserializer

[wet breach]

nbt is something that can be implemented in PHP

I think there is php libs already for NBT

[round agate]

Is this what you want deotime?

[crisp steeple]

well, i dont think you're understanding what im saying

first of all, im not using php for anything

[round agate]

class MyItemStackDeserializer implements JsonDeserializer<ItemStack>
{
  // ...
}

[crisp steeple]

secondly, the problem wasnt making the itemstack, it was deserializing it again on the server

[crisp steeple]

tried this as well for nbttags, problem again was that nbtcompound is abstract so im not able to know what the type of the compound is

[round agate]

maybe look at some nbt open source library, then work your way there.

[crisp steeple]

i looked through a few

[round agate]

I mean

[crisp steeple]

like i said, the main problem wasnt serializing and deserializing the item

[round agate]

if you're using CraftItemStack.asNMSCopy(item), why not use the nms directly?

[crisp steeple]

it was making it compatable with a web api

[humble tulip]

What problem do you have making it compatible?

[wet breach]

you stated you wanted a webview

[crisp steeple]

*web api

i used java spring for it, not php

[wet breach]

therefore there is no issues then

[crisp steeple]

...

[wet breach]

https://github.com/frostalf/JNBT

[crisp steeple]

look

reading the nbt is not a problem

i do that just fine by serializing the item to binary

[round agate]

can you show us what's your itemstack json structure file looks like?

[crisp steeple]

like the actual nbt of it?

sure

ill find an item somewhere one sec

[wet breach]

somewhere you are having an issue that none of us experience

[crisp steeple]

i sort of think we are one two different pages here

[wet breach]

I have serialized MC data before and have displayed it on the web without issues as well as transferred that data to other applications

[crisp steeple]

great, could i ask how?

[wet breach]

the method in how you serialize your data is what is important. You have multiple ways of doing it to include using base64

which base64 works the same regardless of application or it is suppose to anyways

[crisp steeple]

yea, used base64

but the problem is just getting it into a json format

[wet breach]

if its serialized to base64 then all you have is just a string

but it depends on how you decided to serialize everything, whether you serialized it all together as well as if you took out the info you actually needed

[crisp steeple]

i used gson (on many different things, itemstack, nms itemstack, item meta, nbt tag compound), however it is not able to deserialize back into an item on the server due to nbt compound issues

[wet breach]

not sure why you are using NMS for this

[crisp steeple]

im not?

it was just something i tried

[wet breach]

you might not be able to deserialize back directly into an item

instead you might have to manually create the item again using the data you have

[quaint mantle]

newline before braces 🤢

[wet breach]

so you would deserialize the data and then go through the data reconstructing the item using the API methods

[crisp steeple]

here is the current code i have right now: https://paste.md-5.net/heyesocufe.java
this works fine for saving items in a database, and loading them back again when neccessary. however, its not possible to deserialize this on a server (the api) that does not have essential things setup such as the itemfactory

[wet breach]

plugging in as you go the pieces of the data

yeah because you keep using bukkit object output

after I told you not to

if you don't know how to make your own serialization methods, then this is probably beyond your abilities to make

[crisp steeple]

https://paste.md-5.net/famikeroxi.java (custom serialization wrapper class i attempted to make)

i know perfectly well how to serialize things

its just that it is not able to properly serialze the nbt without causing a multitude of issues

[wet breach]

it is, because almost everyone here has done it

[humble tulip]

This is in my main class.

        Bukkit.getMessenger().registerOutgoingPluginChannel(this, this.channelName);
        Bukkit.getMessenger().registerIncomingPluginChannel(this, this.channelName, this.playerManager);

https://paste.md-5.net/uhedofokat.java
In my PlayerManagerClass

I call sendMessage on playerinteract event to debug

I have 2 servers on bungee, server and lobby with one player online in each. I see "Sending plugin message" on the server that's sending but nothing on the server that's supposed to receive it

[wet breach]

please use the paste site

[humble tulip]

o

my bad

?paste

[undone axle]

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

[humble tulip]

editted it

[crisp steeple]

then could you show an example of how to serialize an itemstack directly into json and deserialize again, without using any external apis? thats really all im looking for

[wet breach]

nbt data isn't magical to where you can't deserialize it regardless of application. As I said, you might need to implement something depending on the application you are trying to import the data

[round agate]

I don't know deotime.
But here is what I'm thinking, I think you're trying to make your code as elegant as possible.
If you're serialize thing your way.
Then you have to deserialize it your way too.
Including deserialize NBT in your way. I don't think you can expect NBT to work as you like

[wet breach]

hence why I linked JNBT, allows writing and reading NBT data without needing NMS

that is called implementing

[golden turret]

why nit use BukkitObjectOutputStream?

[wet breach]

without external API's is easy but requires you to implement what external API's have already done and thus make it easier

[crisp steeple]

i am currently, lol

[golden turret]

so why are you wanting gson

[crisp steeple]

so that it can function on a web api

[wet breach]

because we don't want an object, because they want to store the data to be transferrable between applications

objects can be transferred between applications but only if the object is also valid in the other application as well

[crisp steeple]

at some point i was thinking of just making two different storages, one for the api and the other for the actual server loading, although that would be horribly inefficient

[wet breach]

well you are just over thinking this

since we are using Java, the only thing you really need is just the data that describes the item

[crisp steeple]

correct

[wet breach]

if you serialize to base64

it is just a string

[golden turret]

base64?

[wet breach]

and not sure how you are not able to get a valid json object from a string

[crisp steeple]

yes, but what "serialize" method are you talking about? thats the whole thing that im trying to do here

i dont really think im up to making an entire json api thats as good as one created by google

[wet breach]

well, it is up to you. the point I was making is whatever way you decide has to be done in reverse exactly how you did it to serialize regardless of the application

hence you might need to pick out the data you want serialized instead of serializing the whole thing

web api might not know what the heck an itemstack is for example

[crisp steeple]

but all of it is essential though, i cant just have the items on the server losing nbt tags that define important properties about them

[wet breach]

getting the information using API methods isn't different then getting the raw information via NBT

but if you want the NBT raw data then go with that, but don't combine NMS NBT with API methods

[crisp steeple]

dont think i ever did that

[wet breach]

however, since you have an issue with NBT compounds somewhere, I linked you a library that will allow you to arbitrarily create them

[crisp steeple]

i switched a lot between bukkitobjectoutputstreams and json, trying to find something that would work, but never used both of them simultaneously

anyways ill think ill just be done here

not even sure how a 1 month old issue for a server thats pretty much dead now even got brought up again lol

[wet breach]

idk you talked about having issues with serializing

which so far as you explained shouldn't be that difficult

here is a link in how easy it is to create a json object

https://github.com/iso2013/MultiLineAPI/blob/master/MultiLineAPI-Plugin/src/main/java/net/iso2013/mlapi/util/Updater.java#L50-L53

I used json simple for that

not super elegant or whatever, but it gets the job done lol

[crisp steeple]

yes, serializing it is very simple

the combinations of things that worked at some point:

bukkitobjectoutputstream:

serializing: ✅
deserializing: ✅
api compatable: ❌ (not able to deserialze on a server not running minecraft)

---

json (using the gson library):

serializing: ✅
deserializing: ❌ (gson doesnt save types of jsonobjects, nbt tag gets converted into a treemap and doesnt work)
api compatable: ✅

if i ever come back to this, what ill probably do is just make some method to convert json types into nbt compound types

[humble tulip]

thoughts?

[wet breach]

you do know you can serialize the individual stuff and then serialize it all together right?

to avoid breakage like the last bit where nbt tags get converted to something you don't want converted to

[crisp steeple]

not really about serializing it, more about it deserializing which i why i said ill probably make something that individually deserializes them

[golden turret]

i would create a wrapper from scratch

[rigid bridge]

does getLineOfSight() return a block as a string?

[crisp steeple]

why would it do that lol

[vocal cloud]

Docs will tell you what it returns

[quaint mantle]

has anyone got rideable entity NMS code for 1.18

i lost mine

[glossy venture]

you could use nbt for serialization and deserialization
there are a few libraries that allow you to work with nbt outside mc too

only problem is having some serialization/deserialization system for objects

i made something similar

https://github.com/orbyfied/carbon/tree/master/carbon-util%2Fsrc%2Fmain%2Fjava%2Fnet%2Forbyfied%2Fcarbon%2Futil%2Fnbt

only problem is that the client deserialization doesnt work

but if the data isnt sent to the client it works fine i think

it also stays as a runtime object in memory until it is serialozed

[high ridge]

Um is there any recommendations for libraries that make menu guis eaiser.

I haven't touched bukkit since the very early days of minecraft.

[golden kelp]

Yes

https://www.spigotmc.org/wiki/creating-a-gui-inventory/#libraries

what version of Java should i use for 1.15.2?

14

[summer scroll]

java 8 minimum

[hardy raven]

How should I use "nms"?

I downloaded buildtools and ran it in Desktop/NMS (created NMS folder)

[golden kelp]

so imma use 11

[golden kelp]

now use the jar it created in ur IDE

which IDE r u using?

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

I'm having trouble making objects out of config sections. Ive been troubleshooting and I found out that the map I pass into the deserializer doesn't contain the keys at all. https://paste.md-5.net/rahusucori.cs Here is my relevant code and config, This is the first time I'm trying to parse objects like this from the config, so beginner mistakes are possible

[lost matrix]

Does CustomCreatureData implement ConfigurationSerializable?

[crimson terrace]

yes

[lost matrix]

Because the config does not look like its saving ConfigurationSerializables at all.

[crimson terrace]

what do you mean?

[lost matrix]

If you use ConfigurationSerializable then you can no longer write your configs by hand

[eternal oxide]

that config just has a data set. theres no serialized data in there at all

[lost matrix]

I mean you can but you need to be precise

[blazing rune]

How do I save a double or int to a config.yml halp plz

[lost matrix]

Create a list of 3 CustomCreatureDatas and save them in a config. You will see how it looks like.

[lost matrix]

?configuration

[crimson terrace]

will do! Thanks 😄

Whatever. Its FileConfiguration#set(String, Object)
This means you can just use any java object.

I dont think that supports lanterns

As I want to change colours (Red/Aqua, the two lanterns)

okay so it seems i can use the LightFlag enum, but I cant know if theres a lantern entry in it. neither am i able to find the docs

If I encode an Inventory to base64, how long could the string get?

i need to make sure i have a datatype in mysql database long enough for them

i do plan on not allowing books into the inventory

[crisp steeple]

text should be good enough

haven’t had any issues when encoding inventories in base64

[ivory flume]

i feel like that is kinda long

64kb for one player?

i want a smaller one but idk which one to choose, unless 64kb is recommended for the entire inventory

this is a 9x6 inventory btw

[hybrid spoke]

you could also use json or whatever

[ivory flume]

No, I use a task scheduler to repeat every few ticks a message

[ivory flume]

im talking about the database

is mysql

[hybrid spoke]

yes, obv. how long the base64 string could get, what we cant tell you.

[ivory flume]

right, ima have to test soon

[hybrid spoke]

but if base64 is too long for you, you could dodge to another way to store it

like json

but i dont think that you will save much there

[ivory flume]

i think ill be fine

one million players taking up that mucb space would be about 65 gb

not a lot

would VARCHAR(65,535) be good? i dont want to use a fixed length as thatll take space

base64’s output will be different lengths right

thats big

not what i want

i can create a filter

to block books

[hybrid spoke]

item with big lores go brrr

[ivory flume]

medium text is 16,777,215 characters

thats way longer than 65535 characters

👀

all right

first time dealing with databases 😓

thank you

[cobalt dew]

how'd I create a switch statement with pex to check the group?

[quaint mantle]

Hm

There is Maven and...?

[vocal cloud]

Gradle

[quaint mantle]

Ah ty

What do I need to change in an IntelliJ project to change Maven to Gradle and the other way?

[ivory sleet]

You can use the gradle wrapper if it’s from maven to gradle at least

[golden turret]

whyyy

[quaint mantle]

Where do I get that/research about it..

[glass mauve]

maybe getBestPlayers return an Object[]

[ivory flume]

whats pex, whats the group?…

[golden turret]

nop

it is returning a list

[glass mauve]

nvm didnt saw the pic that is 1 px above lmao

[crisp steeple]

list of objects?

idk that’s pretty weird

maybe just try casting it

[patent horizon]

is java 17 compatible with plugin development?

[ivory sleet]

for newer versions yes

[summer scroll]

ofc, in fact minecraft 1.18 requires java 17

[patent horizon]

ah alr

[ivory sleet]

belive there are some libs older versions use that make j17 incompatible with them

[golden turret]

1.18: java 17
1.17: java 16
1.16 and below: java 8 (and java 11, but im not sure)

[golden turret]

the method returns a List<GamePlayer>

but when i do for, it thinks it is Object i guess

[crisp steeple]

ik, it’s weird that it would want object

[ivory sleet]

I mean is your class that has the getBestPlayers method on your compile classpath?

[golden turret]

of course

im using that inside a listener

and everyone is on the same module

[ivory sleet]

yeah certainly a bit weird

might wanna reinvalidate caches

[granite owl]

does unLoadWorld() work properly? i mean since unloading worlds is iirc not known to the vanilla server

[golden turret]

did not work

[ivory sleet]

and no class is protected / packpriv such that it by definition is inaccessible to that other class of yours?

[golden turret]

wdym

the getBestPlayers is public

bro

like

the problem is with List<GamePlayer>

because every for with that is giving me errors

[ivory sleet]

is GamePlayer public?

[golden turret]

yes

[river oracle]

Are you deserializing GamePlayer

[golden turret]

wdym

[river oracle]

Oh are you importing the correct class?

[cobalt dew]

pex = PermissionsEx
group = the player's group

[golden turret]

yes

[summer scroll]

What is the best way to load a user from database? This is my current way https://paste.md-5.net/paqiruvumu.cs

[vocal cloud]

Utils.getidentifier and not just the players UUID?

[ivory flume]

ask PemissionEx devs

[summer scroll]

I want it able to save data with player names too

[ivory flume]

what if they change names

you want to save by uuid internally

then you cna build that data with stuff like Bukkit#getOfflinePlayer

[summer scroll]

I was thinking using CompletableFuture like this to make it more flexible but idk If this is correct or not https://paste.md-5.net/aguxeyabag.cs

[crisp steeple]

would probably use placeholders instead of concatenation for the identifier, to prevent unlikely but potentially possible with your identifier system sql injections

[summer scroll]

placeholders like what?

[crisp steeple]

? (placeholder symbol)

then prepStatment.setString(1, iidentifier)

[summer scroll]

Ah right

PreparedStatement

[crisp steeple]

yea

[summer scroll]

it starts with 0 right?

[worldly ingot]

Indices for statements start at 1

I'm not so sure about that implementation though

I don't even think it will work as you expect because it's just going to return the default user every time, defeating the entire purpose of a CF

If you insist on going that route,

    public CompletableFuture<User> loadUser(String identifier) {
        CompletableFuture<User> future = new CompletableFuture<>();
        Bukkit.getScheduler().runTaskAsync(plugin, () -> {
            // Obviously rewrite this to use PreparedStatements. I'm too lazy
            String query = "SELECT * FROM `" + SQLDatabaseInitializer.USER_TABLE + "` " +
                    "WHERE name=\"" + identifier + "\";";

            SQLHelper.executeQuery(query, result -> {
                if (result.next()) {
                    double coins = result.getDouble("coins");
                    future.complete(new User(identifier, coins));
                }
            });
        });
        return future;
    }```

Though in an ideal world, your SQLHelper would also return a CompletableFuture against which you can call chained CF methods to map it to a User

You then call that method and call upon its future

whateverInstance.loadUser("2008Choco").whenComplete((user, e) -> { // or thenRun() if you don't care about handling the exception
    user.doSomething();
});```

Yeah

[summer scroll]

I use hikari right now

[worldly ingot]

There you go, even better

[summer scroll]

Thank you for the explanation Choco, I'll try it.

[worldly ingot]

tbqh, depending on how your SQLHelper is implemented, the scheduler probably isn't necessary.

It might already be done async. idk

You can return the default user if that user doesn't exist though. But ye, returning the default user every time like you were doing before would just never work ;p

[summer scroll]

Would return null if the user doesn't exist on the database is fine?

[crisp steeple]

personally i would make it return an optional instead of null, but it shouldn’t make too much of a difference

[lost matrix]

Sure. But what i usually do is create a new instance of the user and return it instead.
Then i call my methods something like loadOrCreateX

[summer scroll]

My main idea is to create something like that too.

[lost matrix]

After writing some stuff in Kotlin and Rust i find handling null values quite cumbersome. So i either wrap them in optionals
or dont allow null values anywhere (which is a bit harder to enforce on compile time in java)

[golden turret]

heeelp

[summer scroll]

So If I want to create the loadOrCreateUser method, should I use AtomicReference or what?

[crisp steeple]

maybe just try casting it in the loop and seeing if it works? i’m really not sure why it would be giving that error, maybe it’s something with intellij somehow and not the actual compiler?

[golden turret]

idk

i invalidated the cache

but it did not work

[hushed spindle]

question

i somehow made my plugin able to crash a persons client but not the server itself

how

[golden turret]

fixed

the Game had a type

Game<M>

the classes that were using it, wasnt using atype

i added a <?>

and worked

[hushed spindle]

i implemented a kind of bleed mechanic thing and whenever something dies of said bleed the client shits itself and the cpu usage jumps to 100%

[tardy delta]

i guess theres an error in the console?

[hushed spindle]

nope

the server doesnt care

only the client dies

[tardy delta]

and what does 'the client shits itself' means?

[hushed spindle]

im honestly amazed like i didnt know plugins were capable of that

crashing the server sure but not the client

not responding + 100% cpu usage

gotta shut it down

[tardy delta]

you gotta be doing something in order to make that happen?

[hushed spindle]

i mean obviously

i just dont get what could be causing the client alone to crash

i just know it happens when an entity dies of my bleed damage

[vocal cloud]

Check the client log?

[tardy delta]

it has to do with the impl of your bleeding stuff then

[hushed spindle]

well, yes

[tardy delta]

figure out what you are doing wrong then or paste the code

[hushed spindle]

the log doesnt go any further beyond saying what entity died

i mean thats the thing i dont know what is going wrong, im just assuming it must be some kind of bug with minecraft i exploited

[crisp steeple]

are you using any mods?

[hushed spindle]

how else could it make sense that the client alone suffers from it

only optifine

oh wait i think i know, sec

i think its because i made the amount of bleed particles scale off the damage dealt and i have a custom damage system that has to cause entities to die manually if custom damage were to be fatal to them

so it deals about 10 billion damage to them

🗿

[vocal cloud]

Why not set health to 0 instead of dealing billions of damage

[hushed spindle]

because then the death message becomes "entity died" instead of naming their cause

didnt want that

making a custom damage system sucks, too damn hacky, but you gotta do what you gotta do

[vocal cloud]

Set a custom death message? Idk lol

[hushed spindle]

i mean thats just a big workaround

i could also set their health to something really really low so its basically guaranteed the usual damage would kill them

[quaint mantle]

can i check motion Y player?

[hushed spindle]

sure, just get their velocity

do keep in mind velocity in the Y direction is always a bit negative due to falling

[glossy scroll]

Is there a way to override the default world that is created on startup?

[hushed spindle]

so even when standing on the ground Y motion will be negative

[quaint mantle]

ik

[hushed spindle]

you might be able to use getFallDistance as well but i havent tried

but obviously this would only work if moving downwards

[quaint mantle]

event.getPlayer().getVelocity().getBlockY()

?

or getY

[hushed spindle]

getY

thats their Y motion

add the falling negative velocity and you approximately got your true relative velocity

[sacred mountain]

any ideas on why i cant summon a mob on my server at all?

no console errors

[16:22:57 INFO]: Boncke issued server command: /spawnmob zombieBoncke issued server command: 
/summon zombie ~ ~ ~
[16:23:25 WARN]: Skipping Entity with id zombie
[16:23:25 INFO]: [Boncke: Unable to summon object]```

essentialsx spawnmob command btw, so nothing i've made

spawn eggs dont work either

difficulty is on hard

[eternal oxide]

mobs disabled in server settings?

[sacred mountain]

nope

[eternal oxide]

can you spawn a sheep?

[sacred mountain]

nvm it was a conflicting plugin issue

sorry

[quaint mantle]

how can i got Z coords and compare 3 secong after this 2 ints?

[crimson terrace]

Another question about nms, im sure these are loved by now:
If I extend the LivingEntity class how would I make an entity spawn from there? do I just have to call the constructor and call the teleport() method?

[dense geyser]

bump

[hushed spindle]

is there really no way to damage an entity with a specific damage type

why is there not a LivingEntity#damage(double, DamageCause)

that takes in an EntityDamageEvent but i guess it'll have to do

[silver reef]

Anyone here familiar with EssentialsX and their api? I am trying to listen to one of their events, but for me it doesnt work, if someone else compiles my code, it does work

ill dm

[limpid bronze]

Hey, i'm trying to use this util class https://github.com/Sunderia/SunderiaUtils/blob/main/src/main/java/fr/sunderia/sunderiautils/utils/ItemBuilder.java for setting an item in a inventory. I use ItemBuilder like that :

inventory.setItem(index, new ItemBuilder(item).onInteract(event -> event.setCancelled(true)).build())

But when i interact with this item, it's doesn't cancel the event

[silver reef]

Can anyone help me why my event is not getting triggered? Someone else tested the same code and compiled it himself and that worked.
https://paste.md-5.net/oguremarap.xml

[quiet ice]

how old is your Ess version and what did you test it with?

[silver reef]

tested with spigot 1.18.2

ess is v2.19.4

In this one I tried 2.19.0

Someone told me its more stable for the api

[quiet ice]

?stash

[undone axle]

https://hub.spigotmc.org/stash/

[quiet ice]

Either it is an EssX bug or the event rightfully does not fire

Test the event with /pay

[silver reef]

I did test it like that

it gives no errors, nothing

all the events are not triggering

(all the essx)

[eternal oxide]

I'd guess you have two ess jars on yoru test server

[silver reef]

wdym?

[eternal oxide]

Your code looks fine and your dependencies look fine too. So I'm going to guess you are listening to the wrong event class

[tropic moss]

is there any way to cancel sand and gravel from falling. I've tried canceling EntityChangeBlockEvent and also with BlockPhysicsEvent and they don't work. I know that there's a way with NMS but I will prefer to do it in a simplier way

[eternal oxide]

If no ess events are triggering for you and ess IS running then you have the wrong references

[silver reef]

i thought of that too, I copy pasta's this from the essentials documentation

https://essentialsx.net/wiki/Common-Issues.html

bottom of the page

[limpid bronze]

can someone help me?

[waxen plinth]

@limpid bronze You never call build()

You have to call .build() at the end

This also isn't something I would use

It's going to create a memory leak/performance issues on servers with long uptime

It registers a new listener for each item that has a listener, but never unregisters them

Meaning that every time you construct one, another register is permanently added

So every time the click event is fired it will be slower and slower and take up more and more memory based on how many times you've registered these items

It likely won't cause issues until you have a lot of them but it's definitely not going to be insignificant either, at least for a server with a good number of players

[glossy scroll]

running into trouble using applyPatches.sh in craftbukkit on mac

anyone else have this issue?

[limpid bronze]

oops i forgot that i've already that in my code

but even with build() event.setCancelled(true) is not working

is there a way of unregister when the inventory is closed?

[dense geyser]

does PlayerConnection contain a method for handling every packet?

every packetplayin... packet ^

it seems to, but im not sure

[humble tulip]

Think it does

[tardy delta]

is FileConfiguration#options#copyDefaults(true) setting defaults for when some path doesnt have a value?

[dense geyser]

yes

[dense geyser]

thank ❤️

[tardy delta]

im lookin for a good way to make a lang file thing

i had an enum before which stored paths to where in the config file the entries were saved but that went brr

[humble tulip]

brr

[tardy delta]

maybe java.util.ResourceBundle is something

[quiet ice]

that is my saner way of dealing with it

(i.e. the enum thing)

[tardy delta]

this is what i had before
https://github.com/FourteenBrush/MagmaBuildNetworkReloaded/blob/master/src/main/java/me/fourteendoggo/MagmaBuildNetworkReloaded/utils/Lang.java

[quiet ice]

My more insane way of dealing with it is

    private static final Map<String, Map<String, String>> TRANSLATIONS = new HashMap<>();
    private static final Map<String, String> EN = new HashMap<>();
    private static final Map<String, String> DE = new HashMap<>();
    private static final Map<String, String> DEFAULT = EN;

    @NotNull
    public static final String WRONG_ARGUMENT_COUNT_CORRECTED_SYNTAX = "wrong-arg-count";
    // [...]

    @NotNull
    public static String translate(@NotNull String key, @NotNull Locale locale) {
        Map<String, String> translationTable = TRANSLATIONS.getOrDefault(locale.getISO3Language(), DEFAULT);
        String value = translationTable.get(key);
        if (value == null) {
            PlayerCurrency.getInstance().getSLF4JLogger().warn("Unable to find value for translation key \"{}\" in language table \"{}\".", key, locale.getISO3Language());
            String s = DEFAULT.getOrDefault(key, key);
            if (s == null) {
                return "";
            }
            return s;
        }
        return value;
    }

    static {
        TRANSLATIONS.put(Locale.ENGLISH.getISO3Language(), EN);
        TRANSLATIONS.put(Locale.GERMAN.getISO3Language(), DE);

        EN.put(WRONG_ARGUMENT_COUNT_CORRECTED_SYNTAX, "Syntax error: Wrong argument count. Correct command syntax: ");
        DE.put(WRONG_ARGUMENT_COUNT_CORRECTED_SYNTAX, "Falsche Anzahl von Befehlsparametern. Richtige syntax: ");
        // [...]
    }

[glossy scroll]

is there a way to disable initial world creation or override it in a plugin?

[terse raven]

how do i register a channel that is marked as reserved / access it

[tardy delta]

aah lol

[quiet ice]

I personally think that something like https://github.com/Geolykt/Presence/tree/main/src/main/java/de/geolykt/presence/i18n is more suited to something like this. The idea is still the same as the one I mentioned above just with enum keys - only issue is that there are no default values heh

[tardy delta]

ah i just took a look at the essentials way
https://github.com/EssentialsX/Essentials/blob/8b23c2c4cd140afc0ed697ec4f691a3d7295682e/Essentials/src/main/java/com/earth2me/essentials/I18n.java

resourcepacks maybe?

[quiet ice]

The client always sends the locale of the user

I personally do that (sending messages based on the client locale) in Presence

It won't work on older versions of mc however as those do not always send the locale

[tardy delta]

i love their way for just doing I18n.tl

language thing

[quiet ice]

the client's language locale

Nothing with geolocation (which would legally be a grey area without consent)

That may be illegal

Until they consent that is.

But ask a more qualified lawyer about this, I am not qualified at all about this. I'd recommend to keep your hands off from geolocation for such non-vital usecases unless you are absolutely sure that data protection laws aren't going to kill you either way however

[knotty meteor]

if (p.getInventory().getItemInMainHand().getType() == Material.INK_SACK) {
How do i check if this is GRAY_DYE?

[quaint mantle]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/Material.html#GRAY_DYE

?

[quiet ice]

If you are using MC 1.12 or below I am going to rip your head off (metaphorically that is)

[knotty meteor]

Im using 1.12.2 because i have no choice cause my friends server is 1.12.2 xD

[quiet ice]

But yeah, if you are above that, it is as simple as using GRAY_DYE

[quiet ice]

Good luck on figuring it out yourself.
Just a small tip: Use the damage value

[knotty meteor]

Alright thanks! I will try that

[quiet ice]

They are all magic values however and I have no idea how noone came to the conclusion that this system is a bit dum at that time.
Lemme see how canarymod handled those cases

[tardy delta]

check forum post about old stuff

[knotty meteor]

It works!

if (p.getInventory().getItemInMainHand().getDurability() == 8) {

[quiet ice]

Oh yeah, much better of an idea https://github.com/CanaryModTeam/CanaryLib/blob/master/src/main/java/net/canarymod/api/inventory/ItemType.java#L472.
Far better than whatever we have these days too

[tardy delta]

thats a lot of stuff

;-;

[quiet ice]

that is a rewrite of a fork of hmod, quite different from the bukkit we see these days

[quaint mantle]

who thought it was a good idea to use durability to store magic values

[tardy delta]

i thought this should print "null"

[visual tide]

notch

dont you ned to reload before you save

[visual tide]

idk config was weird af last time i did editing it from the code

sorry
im too tired to understand jokes rn

[midnight shore]

how could i check if a player is in the nether dimension?

[tardy delta]

lets remove the relaod

check their world

[midnight shore]

yes but how do i know if its a nether world?

[tardy delta]

if it equals (or just the name) Bukkit.getWorlds().get(1)

0 is overworld, 1 nether 2 ender stuff and the rest is custom

[quiet ice]

?jd-s this does not seem right

[undone axle]

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

[noble forge]

I was looking at the spec for an area effect cloud and found that this link doesnt lead to anywhere. Anyone know anything?https://wiki.vg/Entity_metadata#Particle

[quiet ice]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/World.Environment.html#NETHER thought so

[hasty prawn]

Pretty sure it's World#getEnvironment()

With the type of Nether like geol said

[tardy delta]

oh there are such methods on a world object

shouldve checked docs

[quiet ice]

Well, it's the WorldInfo object actually

But since World extends WorldInfo, noone will care

[hasty prawn]

Is it? I'm on mobile so I didn't really look that closely

Oh

[tardy delta]

👀

[midnight shore]

would this work?

[tardy delta]

uhm ye

[quiet ice]

Yes

Has anyone ever encountered something like

22:08:08.254 INFO: ClassWriter: Position UNKNOWN in type annotation: @org.jetbrains.annotations.NotNull
22:08:08.254 INFO: ClassWriter: Position UNKNOWN in type annotation: @org.jetbrains.annotations.NotNull

22:08:09.459 INFO: ClassWriter: Position UNKNOWN in type annotation: @org.jetbrains.annotations.NotNull

when compiling? If so, does one know how to get rid of those warnings?

[tardy delta]

does instance = this works in a constructor?

[tender shard]

set <scope> to provided

annotations do not need to be shaded

[quiet ice]

I am pretty sure that it is not related to shading given that I would do it "manually" (and even then I do not). It is probably something inside the java compiler API

[tender shard]

can't hurt to ?paste your pom and the full maven log

maybe we'll find something

[quiet ice]

You see, I am using a mostly custom toolchain

[tender shard]

sure, why not

but why would you ever need that?

sounds like a design failure if you need to do that

public class Test {

    private static Test instance;

    public Test() {
        if(instance == this) {
            System.out.println("Why am I doing this check?");
        }
    }

works fine

[tardy delta]

ah

[worldly ingot]

= this, not == this

[quiet ice]

Code such as

        int valueslen = super.values == null ? 0 : super.values.length;
        @NotNull StateActorFactory<?>[] temp = new @NotNull StateActorFactory<?>[valueslen + 1];
        if (valueslen != 0) {
            System.arraycopy(super.values, 0, temp, 0, valueslen);
        }

seems to cause the warn to appear 4 times extra if not uncommented

[worldly ingot]

but yes to both cases lol

[tardy delta]

it looks like all the things im trying are leading to the same thing

[tender shard]

oh. sure, that obviously also works

I don't see any reason why someone would think that either of them wouldn't work

[dense geyser]

I made some changes to NMS adding a method, and a class, but when I run it on a server, it tells me that the new method and class don't exist. When I run my plugin through luyten, the class and method are there, which signifies its something to do with the server jar (possibly?), does anyone know how to fix it?

[tender shard]

changes to NMS in your plugin .jar? what?

[dense geyser]

nono, I made changes to my spigot jar that you maven import into plugins

i.e

forked spigot

[tender shard]

and did you also use that custom spigot version to run the server?

[dense geyser]

I did not, is that what I need to do lol

[tender shard]

yes ofc

you cannot just change a .jar and then expect it to be included in the official spigot

[dense geyser]

big brain

[tender shard]

https://tenor.com/view/the-universe-tim-and-eric-mind-blown-mind-blown-meme-mind-explosion-mind-explosion-meme-gif-18002878

when you use spigot as dependency in your plugin, it only tells the compiler what methods and classes etc are available at runtime. of course the regular spigot doesn't include the changes you made to your custom spigot version so it cannot work like this

[glossy venture]

just compileOnly your custom jar then

or the source

[tender shard]

whut

they made changes to spigot's NMS code. it makes no sense to shade spigot into the plugin because spigot wouldn't use those shaded classes anyway

plugins use their own classloader

the only proper way to make the spigot server use your custom NMS classes is to actually run the custom spigot version

[tardy delta]

could anyone explain this?

i kinda forgot what it means

[dire marsh]

use object... placeholders instead i think

[tardy delta]

it uses that ye

[dire marsh]

in the method parameter i mean

[tender shard]

there are two methods:

formatted(String) and formatted(String...)

[tardy delta]

ah right

[tender shard]

it doesn't know which one you are calling

if both are the same anyway you can simply ignore it

[tardy delta]

i dont know which one either

dont know the length of the args

[tender shard]

try casting to String[], should work fine

or be on the safe side and cast it to (Object)

[tardy delta]

ye i did

would (String[]) someStr work btw?

[tender shard]

as parameter for your "get" method?

pls show your full class, otherwise it makes little sense to guess

[tardy delta]

i meant this but it doesnt work

[tender shard]

no of course not

you have to do it like this:

String[] arr = new String[] { "sus" };

[tardy delta]

ye so String... converts it to a string array implecitely?

dunno how to type that word lol

[tender shard]

no, varargs works like this:

if you define something like this:

public void sth(String... asd);

then it's the same as this:

public void sth(String[] asd);

there is ONE big difference though

[tardy delta]

ye ik

[tender shard]

using the "..." notation allows you to use both syntaxes:

sth(someArray);
// OR
sth(firstString, secondString, thirdString);

in the method, you will however always receive a String[]

[tardy delta]

cuz you can cast varags to a string array does it mean the compiler casts arguments passed to a string array implicitly?

[tender shard]

no wait

you never have to cast the String... to a String[]

[tardy delta]

so it compiles to sth(String[] str)

[tender shard]

it automatically is a String[]

[tender shard]

yes, but it also sets a flag in the class file that "str" is a varargs

so it allows other classes to also use sth(string1, string2, string3)

[tardy delta]

ah so not really

well ye thanks

[tender shard]

the only difference between String[] and String... is that the latter also allows you to pass normal strings "comma separated"

however, imagine you have this:

public void sth(String asd);
public void sth(String... asd);

and now you do this somewhere:

String asd = "asd";
sth(asd);

now java doesn't know if you want to use the String... thing with only one element, or if you want to use the method that only takes exactly one string

that's why you cast your asd string to either Object or Object[]

[tardy delta]

aah

and i guess its not safe to cast a String[] to an Object

[tender shard]

if you have an array, you won't get this problem, then it's obvious you call the varargs method

you only get this problem if you have a sth(String) and sth(String...) method

my tip is to simply get rid of the sth(String) method

you will never need it

[tardy delta]

makes sense ye

[latent pelican]

Hey, is it possible to run a mcfunction on a spigot server?

[tardy delta]

good

[tender shard]

what is an mcfunction?

[tardy delta]

wondering the same lol

[latent pelican]

minecraftfunction

[tender shard]

what is a minecraftfunction?

[tardy delta]

probably a vanilla command?

or /function

[latent pelican]

probably yeah

[tender shard]

you can use Bukkit.dispatchCommand to force players to run a command

however they need to have permission to use the command

[latent pelican]

I created a random maze and its being stored in a .mcfunction file. However I dont know how to implement this into a spigot server

[tender shard]

as said you can do sth like this

Bukkit.dispatchCommand(somePlayer, "function yourfunctionname");

but that requires players to have the minecraft.command.function permission or however its called

you could simply give them this permission, dispatch the command, then remove the permission again

a bit dirty but I don't see another way to use the function command without allowing players to run ALL functions

[tardy delta]

does Bukkit.getConsoleSender().sendMessage("/function blablabla") also needs permission?

[tender shard]

the consolesender is OP. I am not sure if they have all permissions though

but wait

sendMessage only sends them a message
