[median rock]

They only support sql for storing config :kekw:

[dense drift]

wait what

it uses papi placeholders

[median rock]

Yea, which means you could only display the leaderboard on the ssrver that actually has the stats

[dense drift]

ah so that's what you meant

[errant kraken]

hello, is there a library I could use to evaluate math functions in a string, but replace the operation with the result and keep the rest of the string? something like this: "Hello 2+4*2" -> "Hello 10"

[dense drift]

https://github.com/uklimaschewski/EvalEx but you can't do the hello part

[errant kraken]

hmm ok thanks

[obsidian sonnet]

    private final Set<Toml> config;

    public config() {
        config = Set.of(RandomThings.getPlugin().getTomlConfig());
    }``` 

Two errors are popping up, one saying that variable config hasn't been initialized and another saying that a return type is needed for the public config portion. Do I do what it is suggesting and put void in between public and config?

nvm im big dumb

[high edge]

Did you figure it out?

[obsidian sonnet]

Indeed but i ran into another issue

So the original code i had that was working is on here https://github.com/Williambriggs1/RandomThings

https://pastebin.com/ZPEGYRgN thats my new blockbreak file-
i also removed the [botany] in config file but
it is rough my local host keeps like not responding when i break blocks tbh my old code had no lag even when i spam broke grass in plains-

I was told that the original code was servr intesive so to try and put it into like a set or something when the event was called. but now it continues to throw thread dumps and the server cant keep up from breaking a singular block-

[viral moth]

im not too familiar with all of the method calls your making but it looks like youre putting a lot of stress on your server for no reason

what is your end goal? like what do you want your code to do?

[obsidian sonnet]

Okay so the original in GitHub works- give me a sec to write it out explaining it.

[viral moth]

how new are you to writing code?

because a lot of stuff youre doing is unnecessary

[obsidian sonnet]

Pretty new- what seems to be unnecessary in the GitHub one?

[viral moth]

"_" + event.getBlock().getType().toString().toUpperCase()) the enum is already capital and the toString method is invoked since youre concatenating it with the "_" string

[mental cypress]

You don't need to create a reference to the config each time a block is broken. Just store it as a class variable instead of a method variable unless you do actually have to grab something new each time.

[viral moth]

^ the reason i asked if you were new or not is because you arent really caching data, i would highly recommend watching like a 10-15min video explaining the concept of caching in java on youtube or something

[quaint skiff]

Hi, Do you have any tips how I could code cosmetic armor? I already tried this but it only works sometimes : https://paste.helpch.at/icunifaboy.cs

[obsidian sonnet]

Thank you for the advice I’ll check it out

[west socket]

Anyone with SQL experience know if its possible to select all columns as parameters when inserting?

I have a table with like 50+ columns and I'm trying to avoid typing out all of their names in the SQL statement

[sterile hinge]

Sounds like a table design issue tbh

[west socket]

True

But to be clear, theres no way around typing out all those params?

[sterile hinge]

None that I‘m aware of

[west socket]

Alright thank you

[copper yew]

Hi everyone, I just started java yesterday and I wrote a command to rename items and I want this command to automatically add lore with a player's nickname, like a signature, I used an example from github, but I didn't understand what I need to add in PlaceholderAPI.setPlaceholders(), it must be very simple question, but as I said, I just started doing this yesterday, I would greatly appreciate your help

ArrayList<String> lore = new ArrayList<String>(); String loretext = "Sign by %player_name%"; loretext = PlaceholderAPI.setPlaceholders(idk); lore.add(loretext); itemMeta.setLore(lore);

[edgy lintel]

what is the problem

[copper yew]

what should i put instead of idk in line 3?

[sterile hinge]

the player and the text containing the placeholders

[deep cradle]

Hi

[merry knoll]

if you hover over a method in intellij

it will tell you what parameters it expects

[edgy lintel]

ahh loretext?

also just hover over the method as aki said
it will tell you the data type you need to fill in

is world#unloadChunk async or sync?

[copper yew]

thank you all so much you really helped!

[sterile hinge]

You have to call it synchronously, but best is to not call it

[edgy lintel]

thankyou for your info appreciate it

[merry knoll]

i think paper handles it async

i would check what thread it runs on on load / unload events

[errant kraken]

Hello, how would I go about making some classes invisible to other projects that use my project as a dependency? I want to create an API for my plugin, but I also want it to be the only accessible code

[dense drift]

package private classes, but that will probably not help you a lot, and if you are using uh java 9+ (?) you can specify which modules are exposed

[sterile hinge]

there are several ways on different levels, e.g. modularize it on the project level, use Java 9 modules, use non-public classes

[edgy lintel]

oh alr thx a lot
appreciate it!

[spiral prairie]

extremely stupid question, if i pass a list from class A into class B via constructor, and edit the list in class A, the list variable in class B doesnt get updated, does it?

[merry knoll]

it does

its the same instance of the list

[spiral prairie]

okay perfect

got a little confused during an argument with my friend yesterday

[edgy lintel]

just learn cpp and every copying concept will be understood

java does this by copying pointers (a variable that stores the location of variable)

[spiral prairie]

ye

[edgy lintel]

so yeah

[spiral prairie]

i remember C++, was kinda fun and kinda pain

[edgy lintel]

cpp is pure fun

the pattern got me amazed

all the syntax got me hyped

[spiral prairie]

it probably is fun, i just dont use it on a daily basis

[edgy lintel]

yeah its just hard to use tho

there isnt a lot of good cpp libraries out there

even qt i think its a bad library

but java libraries are all so clean for some reasons

like they are properly organized

because of the java packaging hirerachy and stuffs

and explicit oop

everything is made clear

[spiral prairie]

yep

whatever, fuck cpp

lets write assembly rest api

im wondering

how many septillions of lines of code would be needed to to sql queries?

in assembly

[icy shadow]

many

at least 3

[lyric gyro]

you think so?

[sterile hinge]

pretty sure x86 has an instruction for that

[lyric gyro]

yeah

[obsidian sonnet]

how server intensive would this be where it checks the getTomlConfig when it needs to query which returns config which is set in my RandomThings.java file.

https://pastebin.com/3EA6UHuE < - block break listener

Hey, I'm using React and I'm trying to figure out how to add children to a React.Component.

I'm trying this:

https://paste.developerden.net/ivubuxenum.javascript

But it says index.js:89 Uncaught TypeError: page.addChild is not a function

This is my first time using React, so if you have a better way of doing things I would love to hear it.

[turbid cove]

is theee any way i could pause a bukkitrunnable?

and resume it later, basically i want it to pause if a condition isn't true

[viral moth]

not the runnable itself, no

[dusky harness]

you can have an if statement

if true, return

(or if false)

[viral moth]

but if you are using the scheduler then you can cancel the task and requeue it later

[dusky harness]

that too

[odd prawn]

if (!ifPaused){
run code
}

¯_(ツ)_/¯

[viral moth]

if (paused) return

[dusky harness]

if (paused) {
    return;
}

:))

[turbid cove]

well no cause the task should only run after 15min from starting it

[dusky harness]

I would just start a new task

I mean it doesn't really matter, but that's how I'd do it

¯_(ツ)_/¯

[turbid cove]

start a new task when resuming?

[dusky harness]

yea
like ```java
Bukkit.getScheduler().runTaskLater(plugin, () -> {}, 15 * 60 * 20);

[turbid cove]

yes but then if i start the task and after 5min i pause it, then after 1min resume it the other task would run after 15min

oh wait

nvm

[spiral prairie]

functions have to start with function ...

but what are you doing with react? looking around or want to reach sum

[viral moth]

theyre using a method, not a function

[spiral prairie]

amogus

ok my bad

[leaden sinew]

Something for school

[lyric gyro]

I need a plugin made for $$. Dm me if u can help out

[lyric gyro]

#1004004211945652364

[edgy wedge]

Don't worry it's already there. I asked a bit more for detail and they want a game out of it with a fully fletched out replay system. Pretty simple if you ask me... For as low as $30 if they can

[past ibex]

I want a expert dev working well below minimum wage to make a plugin for me

[mental cypress]

If we're talking an hour, I'll consider it.

[hoary scarab]

According to what HackersDontWin said. The replay system alone is probs a few days xD

[mental cypress]

That's fine

I mean I'm not going to do it but I wouldn't consider it for anything less than 30/hr minimum 20 hours if it's as "small" as they're saying.

[brittle thunder]

https://tenor.com/view/shrek-this-is-the-part-where-you-run-away-get-out-run-away-gif-24468359

[viral moth]

i need 30/h unless its over like 5k

[errant kraken]

What would you guys consider to be better performance-wise: more code in a plugin jar or code split in multiple plugin jars?

[sterile hinge]

that's not relevant for performance

[viral moth]

in the end it all will be loaded by one instance of the jvm so it won't change there. it will just make your life harder, just do one jar

[merry knoll]

what

using file system makes your life harder, just put every single file to desktop

[edgy lintel]

not quite relevant to performance as loading an extra plugin is not an overhead (unless your code massively changes and increases for second plugin)

[merry knoll]

only reason to split your jars is to share some libraries between them

so lets say you use hikariCP on both, you could have a separate jar just for that so you dont have to shade every time

[edgy lintel]

imagine hikariCP as a plugin itself so you dont have to shade no more

like a dummy plugn for library

[merry knoll]

i mean since i use kotlin + coroutines + hikari on almost all my plugins

i usually use them as seperate library

shading the same thing on 3 4 plugins doesnt make sense either

[edgy lintel]

i am kotlin noob so i have no idea what is that lol
but shading is honestly so annoying

yeah

[merry knoll]

kotlin needs to be shaded basically

kinda like a library

[edgy lintel]

wow

[merry knoll]

coroutines are too nice to skip so, kotlin it is when possible

[edgy lintel]

i remember theres like a project where someone does the dependencies shading for you runtime i forgot what was that project called

thought that would be useful for all coding purposes

[merry knoll]

spigot already has it

in the form of libraries

but its kinda messy

it downloads on launch the "libraries" you put down in the plugin.yml

if i am not remembering wrong

[edgy lintel]

oh thats lit i just found it in spigot wiki

does that store the libraries in cache or it actually saves after the server stops

[dusty frost]

Project Loom soon™️

[merry knoll]

pretty sure it saves

although dont quote me on it, have never used it myself

[dense drift]

yes, it creates a libraries folder

[worn jasper]

Any ideas how I can avoid CORS issues while using an api that you don't "own"?

Trying to use the roblox api right now (yes, don't judge :-: or do, cause I should) in the frontend and I am getting issues with CORS

[dusty frost]

I mean that's like the point of CORS, if they don't want you using their stuff, they just set a deny CORS header and you can't use it

what are you even trying to get? like images or something? lol

[worn jasper]

details about a game, specifically players online.

The issue is I think it can't be done in the frontend, it needs to be done in the backend

otherwise it wouldn't make sense... why would they have a public api if no one can use it?

[dense drift]

you are probably just not meant to use it from frontend

[dusty frost]

if it returns JSON, that shouldn't be affected by CORS lol

what specific endpoint are you using?

[dense drift]

https://api.roblox.com/docs looks like json

[keen root]

hi, how can i create a cuboid of smoke particle like a smoke bomb?

[dense drift]

d;world#spawnParticles

[uneven lantern]

org.bukkit.World#spawnParticle

void spawnParticle(@NotNull Particle particle, double x, double y, double z, int count, double offsetX, double offsetY, double offsetZ, double extra, @Nullable T data, boolean force)```

Description:

Spawns the particle (the number of times specified by count) at the target location. The position of each particle will be randomized positively and negatively by the offset parameters on each axis.

Parameters:

particle - the particle to spawn
x - the position on the x axis to spawn at
y - the position on the y axis to spawn at
z - the position on the z axis to spawn at
count - the number of particles
offsetX - the maximum random offset on the X axis
offsetY - the maximum random offset on the Y axis
offsetZ - the maximum random offset on the Z axis
extra - the extra data for this particle, depends on the particle used (normally speed)
data - the data to use for the particle or null, the type of this depends on Particle.getDataType()
force - whether to send the particle to players within an extended range and encourage their client to render it regardless of settings

public static List<Location> generateSphere(Location loc, int r) {
    List<Location> circleBlocks = new ArrayList<>();

    double cx = loc.getX();
    double cy = loc.getY();
    double cz = loc.getZ();

    for (double x = cx - r; x <= cx + r; x++) {
        for (double y = cy - r; y <= cy + r; y++) {
            for (double z = cz - r; z <= cz + r; z++) {
                Location block = new Location(loc.getWorld(), x, y, z);

                if (loc.distanceSquared(block) <= r * r) circleBlocks.add(block);
            }
        }
    }
    return circleBlocks;
}

I use this to get sphere locations

if you modify it a little you can get cuboid locations

and then create particles

[carmine crow]

can i ask there for reviewing my plugin code?

[smoky hound]

you can ask whatever you want, no promises it’ll happen

maybe a #1004004212880977991 or smth. this channel is mostly for answering specific questions. #dev-general might be better to ask for code review

[proper fern]

PlaceholderAPI.registerPlaceholderHook("balance", new PlaceholderHook() { is deprecated..
whats the new one?

[hushed badge]

https://github.com/PlaceholderAPI/PlaceholderAPI/wiki/PlaceholderExpansion#with-a-plugin-internal-class

use PlaceholderExpansion instead

[proper fern]

i can try it xd

[proper fern]

Placeholder Class:
Cannot resolve method 'getBalance' in 'Object'
getList().get(t.getUniqueId()).getBalance();

Main Class:

public static HashMap<UUID, EcoPlayer> list = new HashMap<>();

public static HashMap getList() {
        return list;
}

EcoPlayer Class:

private double balance;

public double getBalance()
    {
        return this.balance;
    }

why i get the error?

[hushed badge]

thats not really a lot to go off, but im going to say that u need to add generics to ur return type of getList

[proper fern]

What do you mean?

[hushed badge]

u should have HashMap<UUID, EcoPlayer> as the return type

u have a raw HashMap type as the return type, which will default to HashMap<Object, Object>, which means that u wont be able to use any methods from EcoPlayer

[proper fern]

yea its working a half

now its had a red line

i cant send images here

[neat pier]

Uploading Images

You won't be able to upload images here directly to avoid spam, so please use https://imgur.com/upload or similar service to upload images/screenshots.

[proper fern]

ah

[proper fern]

https://imgur.com/TqO6TIp

[hushed badge]

that says what the issue is

ur returning a double, when u need to be returning a String

[nimble vale]

what you guys are using as a redis api/library for plugins

[lyric gyro]

jedis

[nimble vale]

yeah idk i saw a plugin api DeltaRedis it just seems so easy

and plain jedis is painful

maybe i can wrap it up

[proper fern]

how can i change that

[hushed badge]

it doesnt really get more simpler than this - String.valueOf(double)

[reef delta]

Having a "moment" right now- why is args.length < 2 always false?

[nimble vale]

if (args.length < 1)
else if (args.length < 2)

[proper fern]

okay get it, and how can i call it with the player?

public void joinPlayer(Player p)
because i want to register the placeholder under this

[nimble vale]

wait a second

[reef delta]

Exactly. 😆

[nimble vale]

you are already using args[1] when checking if it is null

[reef delta]

Just noticed haha, cheers.

[nimble vale]

lol got me

[nimble vale]

you don't need to use jedis in proxy right? only spigot servers

so actually you just messaging between servers and not with proxy

[lyric gyro]

you need the redis client anywhere you want to communicate with redis

if the proxy plugin needs to use the redis server, then you need the redis client in the proxy plugin as well

if not then, well, then no

[nimble vale]

alright thanks

thats what i need

[lyric gyro]

epic

[nimble vale]

there is also rabbitmq and lots of other concepts for this purpose i dont really know how to choose one between these options

i think im just gonna use redis

[dusty frost]

rabbitmq 😌

redis is probably better lol

it's a lot simpler

[reef delta]

I'm guessing it's only viable via NMS, but is there a way in SpigotAPI to get a player's visible BossBars?

[deep cradle]

If you need save message not read you can use Rabbitmq but i prefers pulsar for that

[dusty frost]

okay Pulsar might actually be really cool

looking at it, it looks kinda nice, and if it's easier to setup than RabbitMQ, I might just be down

[west socket]

Anyone know how it could be possible that I'm getting a NPE here
Bukkit.broadcastMessage(upgrade.refName);
Yet it's still printing out the expected (non-null) result?

I'm really stumped about this

[dusky harness]

show the exception

[viral moth]

the only way you could get an error is if upgrade is null. So that is most likely null. However sending the exception itself would help more

[dusky harness]

probably getting an error after that line

[west socket]

https://paste.helpch.at/gezisabijo.cs

Thats the line 118

[dusky harness]

Oh you're using an old java version :((
Try printing out upgrade

and also just making sure - that line is in onOpen?

[west socket]

Yeah it is

[west socket]

This line of code returns the proper name in chat

Ill try recompiling with a basic sysout though

[viral moth]

why are you working with the 1.8 api?

[west socket]

My server is running on 1.8, but that shouldn't be relevant to this situation

[viral moth]

im assuming youre making a server for 1.8 but you could make a 1.19.x server and use viabackwards to support older versions. its not relevant but i was just curious

^ would give you more api features

[west socket]

I do it for the performance

Not compat

[dusky harness]

seeing as the name is PitRemake I'm assuming it's a pvp server

[west socket]

Yes

[dusky harness]

so I'd recommend using 1.8

[west socket]

I hate how people who argue against using old versions completely ignore the question of server performance

[dusky harness]

although besides pvp stuff I'd go with 1.19 over performance

[west socket]

My plugin is super CPU and memory heavy, so I really can't run it 1.19 effectively

Anyways

Let me test this

[dusky harness]

alr

if you want you can make a bunch of prints to see where the exception occurs

if you don't want to nullcheck everything

[west socket]

Yeah so the sysout line errors

yet prints

Idek how thats possible

[dusky harness]

print after the broadcast

I'm guessing, for some reason, java is messing up the line numbers

[west socket]

Yeah the method still runs

Completely

In-game everything works as it's supposed to

[dusky harness]

did you add a print at the bottom of the method?

[viral moth]

i think optimizing your code should fix your problem there. its your call but you do you. newer versions arent my favorite for performance but have more features. anyways ill get back on topic

[dusky harness]

I'd say to use 1.8 for pvp, if it was only for performance I'd go with 1.19 and optimize

[west socket]

Most of it can't be optimized

[viral moth]

could i ask why?

[dusky harness]

well plugins can, especially if you're the developer

[west socket]

Most of the lag boils down to nms

I'm basically running a shit ton of fake players fighting at the same time

and the Attack Event calls

Are super heavy on CPU

[dusky harness]

well I don't think that's the cause of NMS

but anyways, back on topic
If you add a print to the bottom of the method, does the exception print after or before your print?

[west socket]

Let me try that

[dusky harness]

alr
I've also gtg rn

[west socket]

Ok

Well exception happens after

When the sysout is at the end of method

[viral moth]

it still prints but throws the exception?

[west socket]

Yes

It's a very strange situation

[viral moth]

it is still saying that Bukkit.broadcast is causing the issue?

[west socket]

Yeah

[viral moth]

if you comment it out does it error?

[west socket]

Anything referencing "upgrade"

Will throw NPE

But Upgrade is not null

[viral moth]

print out upgrade

just to be sure

[west socket]

Thats what I did

It prints out just fine

Only thing I could think of is double loaded plugin

but thats not the case

[viral moth]

something is making it null then, from the information youve given, it should work fine but it clearly isnt

[west socket]

Well the thing is

In game works completely fine

It changes ItemStack lore based on values of "upgrade"

That appear completely fine

But the NPE throws still

[viral moth]

could you send the code?

[west socket]

Yeah sure

https://paste.helpch.at/ninucareva.cs

Line 13 in that

is where it errors

And line 15 errors if I remove the broadcasts

I don't think it's a small issue, but something larger with how the class is being loaded or something

Because this code used to work fine

[viral moth]

i would disagree

im still assuming that upgrade is null

[west socket]

Then how could the broadcast display upgrade.name?

[viral moth]

put this above the broadcast statements
assert upgrade != null;

and that will throw an error at runtime if it is null

[west socket]

Same result

[viral moth]

ok

[west socket]

Error throws at broadcast line

Not assert line

[viral moth]

my bad

assert did not do what i thought it would

but i still think upgrade is null

because thats what the exception is telling you

[west socket]

Yeah but it literally isn't

the broadcast prints out "Perk Upgrade: First Strike"

Or whatever other upgrade value I select

I know it's horrible coding, but I'm really struggling to not just catch and ignore it right now

[viral moth]

id suggest only using a try catch if you know why the exception is thrown

[west socket]

Yeah I'm aware

[viral moth]

i dont think i can help and further because i havent worked with the 1.8 api (it should work fine but there might be something happening that i just dont know about)

[west socket]

Well the issue is clearly within Java, not the 1.8 API

considering that any usage of "upgrade" will produce the same

[viral moth]

idk what version of java 1.8 requires

[west socket]

Broadcast or not

Java 8

[viral moth]

are you restarting your server each time youre trying your plugin?

[west socket]

Yeah

[viral moth]

welp

i wish you luck lol

[west socket]

Thanks

Okay update, there is another method that pulls the same "upgrade" object from the HashMap during the InventoryClickEvent for that inventory.

And that one preduces the same NPE, but "upgrade" is actually null this time

So I suspect maybe it's being removed from the Map it's being fetched from very quickly after it's fetched

Somehow causing an NPE and the code to still run?

Okay, yeah I found the issue

I was removing the upgrade object from the Map with the InventoryCloseEvent

Which for some reason is now being called when I switch from one inventory window to the other

Not sure why an issue like this would prop up all of a sudden

I guess the timing of it being removed and called at the same time somehow caused it to error and run the method at the same time, very strange.

[turbid cove]

Hi, i want to make a plugin that adds 100pts to a faction (gradually 25pts/15min) But if two conditions are not met it should stop and resume when those two conditions are met how can i do this with bukkit?

also one of those conditions is checking if a olayer is in a radius from a certain location

[west socket]

You can use location.getNearbyEntities(xRadius, yRadius, zRadius)

And then just check if the player is in the List that it returns

If you want a timer that can start and stop, I would recommend using a BukkitRunnable that increments an integer for each guild every second if the requirements are met

And then reward them and reset it once that integer reaches a target, (15 * 60) or something

[turbid cove]

wouldnt that cause lag?

if there is a lot of factions?

[sterile hinge]

I don't fully understand how it's supposed to work with pausing and resuming but you can simply calculate the distance from the player to that location

[turbid cove]

basically to add those points to the faction you have to wait 1h (add 25pts each 15min) BUT if the player is not near a certain location (this is not the problem) it should stop counting and wait until he's in that radius

what i'm struggling with is pausing and waiting for the player to be in the radius then resuming

[sterile hinge]

I guess you don't need an incredibly high precision there, so you could just check every second and count one up

[turbid cove]

ok but is it efficient to make a runnable for each faction?

[sterile hinge]

you can also have one task for all factions, but that won't make a noticeable difference most likely

[high edge]

I mean you probably won't have the amount of factions where it'd actually be noticeable

[nimble vale]

is there a way to disable the default italic in adventure api

i don't really wanna type decoration thing every time

[sterile hinge]

that's not in adventure

if you mean the italic lore texts

[nimble vale]

lores item names

yeah

[sterile hinge]

that's in the client basically, there's no other way than explicitly setting italic to false

but you can just write a method for that, no need to duplicate code

[nimble vale]

yeah it's not that convenient but it works i guess

[merry knoll]

is there a way to see if the player connecting (aka on join) is joining from another bungee server?

i guess i could listen to "bungeecord" plugin channel?

[azure trench]

Cannot resolve method 'getServer'

Anyone help?

[fiery pollen]

show code

[azure trench]

getSever().dispatchCommand(getServer().getConsoleSender, "lp user %player_name% parent set vip");

@fiery pollen

[merry knoll]

where are you running this code?

it needs to be in a JavaPlugin instance

[azure trench]

Intelij Idea

.java

[merry knoll]

send full code please.

[azure trench]

why need full code lol

https://imgur.com/a/6zRj0pa

here is.

[merry knoll]

because your answer shows that you are new to java

[azure trench]

Yes

[merry knoll]

you need a reference to your main plugin class

getServer is a method for JavaPlugin

its not available for commandExecutor

[azure trench]

so?

[merry knoll]

^ this

you need to do dependency injection

or have a static instance on your main plugin class

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

here

[azure trench]

if (!(sender instanceof Player)) {

?

[dusky harness]

You can also use Bukkit.getServer()

dependency injection could be a bit complicated

depending on what stage you're on atm

[azure trench]

Does not work, i tried.

[dusky harness]

what error?

also make sure it's getServer(), in your code you have getSever()

[merry knoll]

yeah but i feel like learning about oop is a must if you want to do any java work

[azure trench]

Yeah, but don't work.

[dusky harness]

what error?

[merry knoll]

otherwise same issue will pop up and it wont have a static access point

[azure trench]

.

i tried with import org.bukkit.getServer;

and import org.bukkit.Bukkit.getServer;

[merry knoll]

dont touch imports manually

[azure trench]

It's same

[dusky harness]

are you doing Bukkit.getServer() in the code

not in the imports

[azure trench]

No.

[dusky harness]

try that

and lmk if it works or the error if it doesnt

[azure trench]

Cannot resolve symbol 'bukkit'

[merry knoll]

Bukkit

[broken elbow]

uppercase B

[azure trench]

bukkit.getServer().dispatchCommand(bukkit.getServer().getConsoleSender,

[merry knoll]

not bukkit

[azure trench]

same

Cannot resolve symbol 'Bukkit'

[dusky harness]

try importing that

using intellij's auto import (alt enter on Bukkit should work)

[azure trench]

It's wwork but

[dusky harness]

also note that Bukkit is a class (such as Player and String) which means it can hold variables and methods (such as getServer()), and they're always UppercaseLikeThis (like how Player and CommandSender are uppercase)

[azure trench]

Cannot resolve symbol 'getConsoleSender'

[dusky harness]

I think it's just Bukkit.getConsoleSender()

[azure trench]

Bukkit.getServer().dispatchCommand(Bukkit.getServer().Bukkit.getConsoleSender, "lp user %player_name% parent set vip");

So I make this.

and error:
Cannot resolve symbol 'Bukkit'

@dusky harness

[dusky harness]

Did you import Bukkit

if not ig manually put import org.bukkit.Bukkit; at the top

[merry knoll]

since it got pushed up, anyone know a way to listen to player send event? (aka from server to server through bungee)

[azure trench]

i already have it

[merry knoll]

probably listen to packets?

[dusky harness]

show full class again

just so that i can see updated file

[hushed badge]

dispatchCommand(Bukkit.getServer().Bukkit.getConsoleSender,
the issue is here
it should be dispatchCommand(Bukkit.getConsoleSender(), etc
u should really learn java before trying to make plugins

[azure trench]

Bukkit.getServer().dispatchCommand(Erbex.commands.Bukkit.getConsoleSender, ("lp user %player_name% parent set vip"));

lol bruh

i had it

[hushed badge]

thats not even what i wrote

[lyric gyro]

uh

[broken elbow]

if your plugin is bungee, there's an event for it

[west socket]

There’s a luckperms api you know

[merry knoll]

no

[lyric gyro]

I would not suggest this person to use the LP API lmao

[hushed badge]

lets not bother with LP api right now

[merry knoll]

my guess is that i can listen to pluginmessaging packets?

[west socket]

Oh my bad, didn’t see context

[dusky harness]

oh how did i not see that lol

[west socket]

Bungee plugin messaging is so aids

I used it for my skywars queuing system and I still hate it

Regret not just using the time to setup redis or something

[high scarab]

You should learn java before coding bukkit plugins...

[merry knoll]

yeah, but the issue is its not my setup

[west socket]

Ah

I see

[merry knoll]

and im running into some mysql race condition issues

when players are switching servers

[west socket]

Sounds fun

[merry knoll]

imma just listen to packets and delay the switch

manually i guess

[azure trench]

Bukkit.getServer().dispatchCommand(Bukkit.getConsoleSender, ("lp user %player_name% parent set vip")); ?

[west socket]

Not sure why there’s parenthesis around the string, but that should work

[lyric gyro]

getConsoleSender**()**

[west socket]

Ah

[neat pier]

FAQ Answer:

Online Courses:
Online courses are also great for learning java. Some websites that offer them are:

• Coursera - Free unless you want a certificate
• PluralSight - Great courses from what I've seen. Mostly Paid
• Udemy - Never used them myself but they seem to all or at least most be paid.
  My first ever course was one from Coursera. - I can say it was pretty good at introducing me to the programming world as a whole not just java.

Oracle Docs:
Oracle docs can help a lot at learning and understanding java:

• Start with this,
• Breeze through this (skipping stuff that doesn't seem relevant like bitwise operators),
• Hit this.
  They're the first three from this larger thing which you should definitely go through overall. But those three should be enough for slightly better understanding of what is happening here without feeling like a huge time sink.
  That one is a small part of this larger site wherein "Essential Java Classes" and "Collections" also have good useful stuff

Other services:
Some other cool services that will help you learn java are:

• SoloLearn
• W3Schools
• JetBrains Academy

As you can see there are plenty of good ways to learn as long as you're willing to invest the time. Have fun learning!

@azure trench you might be interested in

[azure trench]

Bukkit.getServer().dispatchCommand(Bukkit.getConsoleSender ("lp user %player_name% parent set vip"));

?

[west socket]

Add () after getConsoleSender

[azure trench]

ok, ty. I will see.

Huh.

[west socket]

Also I don’t think that placeholder is going to work the way you want it to

[azure trench]

I will check it.

If don't work, I will see error then I will fix it :)

So, that error I fix it.

[west socket]

Is that supposed to be a PlaceHolderAPI placeholder?

[azure trench]

Yes

[west socket]

Those aren’t going to work in your code unless you’re using PlaceHolderAPI as a dependency

And use their API to register it

What IDE are you using?

[azure trench]

Java

[west socket]

I don’t think that’s what you’re trying to do though

What software are you using

To compile code

[azure trench]

Intelij Idea

[west socket]

Ah okay

Can you send the entire method where you’re trying to run that code?

[azure trench]

You mean full code?

[west socket]

Yeah

[azure trench]

1S

I need to change this, later. Because I don't think so it will work, Probably if I type /grandmod command will run only for that who type that command.

https://pastebin.com/CAzrNAah

[west socket]

Oh so are you trying to have the player type in the username or who they want to change the rank of?

[azure trench]

To change someone rank..

[west socket]

Yeah

[azure trench]

Like /grandmod wiji

[west socket]

So you want to do that with parameters

[azure trench]

Yeah

[west socket]

I mean arguments

So you see the args variable

That’s going to be a String array (essentially a list) of all the words the player types after the command

So if you fetch args[0]

That will be the second word the player types

[azure trench]

I have that :)

Check pastebin

if (args.length > 1) { System.out.println(" You GrandModed " + args[0]); p.sendMessage(" You GrandModed " + args[0]);

[west socket]

Oh I see

My bad

[azure trench]

No, enjoy.

No problem.

[west socket]

Okay so

You need to get the player object

[azure trench]

So I need to replace %player_name% to args[0] ?

[west socket]

No

Because args[0] is just the name

Not the actual player object

To get the player object, you need to loop through all online players

[azure trench]

arg[0] equals to player name ( that who I want to give to someone)

right?

And arg[1] queals to my name

[west socket]

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

}

Then in that

[azure trench]

Player p = (Player)sender; String name = p.getDisplayName(); { if (!p.hasPermission("can.build")) {

That what I have.

[west socket]

Put if!(player.getName.equalsIgnoreCase(args[0])) continue;

Let me get on a computer, hold on

Here

public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {

        if(!(sender instanceof Player)) {
            return false;
        }

        Player p = (Player) sender;

        if (!p.hasPermission("can.build")) {
            return false;
        }

        if(args.length < 1) {
            return false;
        }

        Bukkit.dispatchCommand(Bukkit.getConsoleSender(), "lp user " + args[0] + " parent set vip");
        p.sendMessage(" You GrandModed " + args[0]);
        

        return true;
    }```

[azure trench]

Let me check.

Before that.

Thank you :)

[west socket]

Np

But I really would suggest learning more about SpigotAPI and Java in general

I also started SpigotAPI with little to no java knoledge, which is something I regret

I know it may seem preachy, but I really think you can learn a lot faster if you actually understand what the code you're writing means on a code-base level

[azure trench]

Yeah, You are right.
I need one more year, then I will start to learn programing in school

[west socket]

Ah

[azure trench]

Then It will be more easy.

[west socket]

Java really isn't too hard if you know the basics

[azure trench]

Yeah.

I started to learn smth.

A little, but I will learn.

[west socket]

Once you understand it, you can gradually learn more of it as you need it in your projects

[azure trench]

Like you said, is not hard.

Yeah, you are totally right.

[west socket]

Don't worry, there really aren't many great sources for learning spigot API out there

I think it's a pretty good start for practicing Java

[azure trench]

Ok, let me check about this.

[mystic gull]

Hello, i see many dev and the spigot classes where they use variable names like var0,var5 etc... does it mean smth for them ?

[high edge]

compiled code, not actual variable names

[viral moth]

I would recommend using the luck perms api instead of commands

[west socket]

Yeah I would too

He clearly has no Spigot experience

So I was just helping him get something simple working

[viral moth]

I know it's not you're issue but I saw your code snippet

[west socket]

Yeah

[merry knoll]

locks you place on sql gets released once you commit right?

as in connection.commit() when autocommit is set to false would release all the locks placed in that transaction?

[sterile hinge]

what kind of lock are you talking about

[merry knoll]

a row read - write lock

using for update syntax

running into some race condition issues where data is not fully saved before its being read again

[sterile hinge]

well, according to the docs the commit method releases the locks

[merry knoll]

yeah thats what i read as well, but a lot of stackoverflow threads popped up where people were saying that its still locked

so im kinda confused

[sterile hinge]

if an implementation doesn't keep to the spec, that's a bug

[azure trench]

It's work, Thank you again :)

[glad walrus]

Hey guys any help here would be very much appreciated

https://github.com/PlaceholderAPI/PlaceholderAPI/issues/871

[dark garnet]

hi, how can i make a super accurate method to get the entity (specifically a player) that a player is looking at? i also need a way to get the exact coordinates (down to the decimal) a player is looking at, how can i do this (im using targetblock right now, but its not very accurate)?
for reference, im making a laser gun

[dark garnet]

and when hitting a target, i want the particles to hit the player where the attacker was looking, cause rn it just locks to the opponent's eye level (and then i subtract 0.5 from the y so it doesnt look stupid)

[west socket]

What I would do is draw a particle trail on the player.getLocation().getDirection()

Segment the vector into multiple pieces and loop through each segment

Draw a particle there and check if there is a player nearby to the location

[lyric gyro]

World#rayTrace/rayTraceBlocks/rayTraceEntities

[lyric gyro]

Please help, why does the LocalHost Server work perfectly and there are a lot of bugs on the hosting?

[slim vortex]

Did you make sure that the production is set up identical to the development environment and actually has the updated plugins?

[dark garnet]

rayTraceEntities is detecting the player that activates it

[spiral prairie]

what kind of bugs?

no, just predicate (emily you)

[lyric gyro]

there's one rayTraceEntities that takes a Predicate so you can filter which entities it'll hit (or not)

[dark garnet]

yeah the normal rayTrace

o wait

[lyric gyro]

Ah well yeha that's the one :d

[dark garnet]

there r multiple rayTraceEntities

[lyric gyro]

hard to remember them all lol

[dark garnet]

y didnt intellij tell me that there were multiple >:((

[lyric gyro]

it hates you

[dark garnet]

😭

what exactly is raysize?

[spiral prairie]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/World.html#rayTraceEntities(org.bukkit.Location,org.bukkit.util.Vector,double,java.util.function.Predicate)

this is probably what you want

[dark garnet]

ye

[lyric gyro]

ray size is basically how much leeway the ray has to consider "hitting" something

[dark garnet]

so like the "thickness" of it?

[spiral prairie]

just use the method that doesnt have that parameter

you can change it if you notice issues

[dark garnet]

o didnt know there was one without it

[spiral prairie]

i literally sent it

[dark garnet]

i thought that was the same one, mb

[spiral prairie]

xD dw ab it

[dark garnet]

will using lots of rays lag the server?

[spiral prairie]

spigot gets confusing sometimes

[dark garnet]

like a bunch of players shooting laser gun

omg the ray tracing works (at least for blocks, gotta test players later), tysm guys

[spiral prairie]

if you have like 100.000 simultaneosly, yes

[dark garnet]

so it can handle a good amount?

[spiral prairie]

id guess so

[dark garnet]

its not just gonna die if like 10 r fired

[spiral prairie]

def not

[dark garnet]

alr that should be fine then

[merry knoll]

if the implementation is like normal raytracing internally

distance effects its performance

[dark garnet]

yea if i notice any lag ill reduce distance, i have it as 30 rn

[spiral prairie]

i think mc default is somwhere with 12

[dark garnet]

also just figured out i can just use rayTrace instead of both rayTraceBlocks and rayTraceEntities lmao

[merry knoll]

you can divide it as well

go chunk by chunk etc

[spiral prairie]

if thats what you want

[merry knoll]

i wouldnt do any preemptive optimizations though

make it and test then go from there

[dark garnet]

yea i feel like i'd just break more than i'd fix

[dark garnet]

yea i was using both at first (so it casted 2 ray traces each time)

cause i started without knowing it returned RayTraceResult

[warm steppe]

@Override
public String onRequest(OfflinePlayer player, @NotNull String params) {
    return String.valueOf(Bukkit.getOnlinePlayers().size());
}

@dusk crypt

https://github.com/PlaceholderAPI/PlaceholderAPI/wiki/PlaceholderExpansion#full-example-2

pretty easy

[dusk crypt]

I'm sorry, I just started doing it. so I don't have any idea yet how this works.

[warm steppe]

This is if you want to make it in your own plugin

If you dont want to make your own custom placeholders, you can use server expansion

https://github.com/PlaceholderAPI/PlaceholderAPI/wiki/Placeholders#server

[dark garnet]

hi, this is just a general question, how do i disable the /tell command? not from a developer pov, i wanna do it using permissions, but minecraft.command.tell doesnt tab complete in luckperms (which means it doesnt exist)

[warm steppe]

no, it doesn't mean it

[dusky harness]

I think the perm is minecraft.command.msg

and for tellraw it's minecraft.command.tellraw

I'm just going based off of https://bukkit.fandom.com/wiki/CraftBukkit_Commands 🤷

[lyric gyro]

It does not mean that at all, suggestions are mere suggestions, as in LP will show what it knows so far, maybe some permission hasn't checked and since plugins can check for literally any permission in existence ever, LP can't know about all of that until they are checked, suggestions are not the final word of "this exists or not", you're gonna find this useful for debugging and finding permissions https://luckperms.net/wiki/Verbose

[dusky harness]

I think mc/bukkit permissions auto complete though

along with plugins with the perm in plugin.yml

but besides that I don't think it does

[lyric gyro]

"yes"

not necessarily but for the most part yes

command permissions are checked when you log in, so they get added to the internal "known permissions" set as soon as someone joins

[dusky harness]

oh really?

[lyric gyro]

yes

[dark garnet]

well yea ik that its not super accurate for stuff like plugin permissions
but i assumed that the vanilla mc cmds were all accurate

[dusky harness]

try this perm
or use lp verbose

[dark garnet]

ill try verbose
msg permission didnt work

[lyric gyro]

tell is also an alias for msg as dkim pointed out :d and they share the same permission

[dark garnet]

u sent before i finished editing

[dusky harness]

wait what its an alias?

oh wait

are tell and tellraw completely different

[dark garnet]

yeah but ig not technically

[dark garnet]

yes

[dusky harness]

oh lol

[dark garnet]

tell = msg = whisper

[dusky harness]

I was thinking tell similar to tellraw

[dark garnet]

same

[dusky harness]

¯_(ツ)_/¯

[lyric gyro]

tellraw is for sending json components lol

[dusky harness]

but if it's alias it would most likely have the same permission

[dusky harness]

ye but I thought tell was the non-json version of it

🤷

but without the "player whispered" part

It was just a guess

[dark garnet]

it doesnt for some reason

[dusky harness]

I always use /msg

[dusky harness]

You sure?

did you try the msg permission

[lyric gyro]

yeah well, 2015 mojang decisions lol

[dark garnet]

yea

players cant do /msg but they can do /tell

[dusky harness]

did you try verbose

[dark garnet]

no not yet im about to

[dusky harness]

alr

lmk what the results are

im curious too

[lyric gyro]

maybe some plugin is overriding the command and has a different permission?

[dusky harness]

also that reminds me
why does ESX make their own versions of mc commands

usually worse versions

[dark garnet]

it says minecraft.command.msg....

[dusky harness]

💀

Uh

try the permission check cmd

it changed so i dont remember what it is

i think its like /lp user dkim19375 permission check minecraft.command.msg

[dark garnet]

player said that /tell appears red

but they can still do it

[dusky harness]

Did the verbose say that they had perm?

it should've been like red or green

[dark garnet]

lemme check with them

it says false

[dusky harness]

and that's the only permission shown?

[dark garnet]

but it still worked lmao

https://srnyx.likes.cash/java_Jg064hkyTZ.png

[dusky harness]

Maybe try just doing /verbose on

[dark garnet]

that spammed a lot

[dusky harness]

only thing i can think of now

[dusky harness]

yep

it shows every perm check

hopefully this isn't on a public server

you can also upload the results to the web

[dark garnet]

it is, why?

[dusky harness]

well ig it doesn't matter since the web should be able to filter it out

[dusky harness]

spamming

[dark garnet]

it only shows to me i think

should i have them run /tell?

[dusky harness]

ye but each player will have their own perm checks

[dark garnet]

o ye

[dusky harness]

nono

[lyric gyro]

huh sounds like another plugin is forcing the command to run or sending the message on its own or something

[dusky harness]

ask them to upload the verbose results to the web

since maybe it cancels and runs it separately or something 🤷

which I don't see why but it's the only thing i can think of

either that or a plugin is somehow forcing it to run

which is what emily mentioned

[lyric gyro]

yeah i mean it doesn't make any sense for /msg to work fine but not /tell since they literally redirect to the same command object

so it's not the permission

[dusky harness]

do they have plugman

srnyx

[dark garnet]

no

[dusky harness]

okay

[dark garnet]

imma just leave it as is cause we're about to install new chat plugin anyways

[warm steppe]

huh

chech your chat plugin's permissions

and block it's /tell permission

[lyric gyro]

the thing is that it isn't checking any other permissions

it's checking whatever verbose is reporting

which is the vanilla's msg/tell/whisper permission

but something else is taking that, not giving a shit and doing the thing anyway

[spiral prairie]

Hi, quick question.
If I need to return Map<Integer, InterfaceA> and return Map<Integer, ClassA> where ClassA implements InterfaceA, it won't compile.
Any stuff i need to do to make java realize that ClassA inherits from InterfaceA or am i doin something stupid?

[icy shadow]

this is an intentional thing for safety

Map is invariant because otherwise you could get bad errors

[spiral prairie]

right

how fix

[icy shadow]

lets say you also have ClassB and call put, a Map<Integer, ClassA> would throw an exception but the type system would think it's safe

you should be able to do an unsafe cast i think, or you could change the type to Map<Integer, ? extends InterfaceA> on the basis that will probably break other things

you just need to make sure that you're very careful with the unsafe casts

because they are unsafe

[spiral prairie]

this seems to at least compile

[icy shadow]

yeah it will probably change stuff in other places

you're explicitly making the parameter covariant, which means that get will be safe but put will not

[lyric gyro]

big words

[icy shadow]

yeah

big like me

[lyric gyro]

oh

🤏

[torpid raft]

pedantic but is it actually ? extends InterfaceA or is it ? implements interfaceA

[lyric gyro]

in the context of wildcards it's always ? extends T to mean "It produces instances of some subclass of T", and ? super T to mean "It takes instances of some superclass of T"

[icy shadow]

big words

[torpid raft]

i see, i think

[icy shadow]

tldr it's always extends even for interfaces

[torpid raft]

ye

? super T seems interesting though, i didnt realize that existed

seems like the uses for it would be very niche

[lyric gyro]

Not really

[lyric gyro]

List<? super File>
The list contains instances of some superclass of File, but you don't know what superclass exactly, it could contain Comparables, it could contain Serializables, it could contain Files themselves or even Objects; but you don't know which one exactly so you can't take/get any instance from it, all you can do is add File instances (instances of a subclass of File still count as an instance of File, so it isn't constrained to File.class specifically), because a File is (in this context) a superclass of File

List<? extends Number>
The list contains instances of some subclass of Number, but you don't know exactly what subclass exactly, it could contain Integers, it could contain Longs, it could contain both (List<Number>) or a BigDecimal; but you don't know what subclass exactly it has so you can't put/add any specific Number instance, all you can do is get Number instances from it

More generally speaking: PECS (Producer Extends; Consumer Super), the wildcard is bounded with extends when the parameterized type produces T's, and it's bounded with super when it consumes T's, as in Supplier<? extends T>, Consumer<? super T>, Function<? super T, ? extends R>

How to spawn an item at a specific location in the Inventory?
For example,i give myself a diamond in 8 slot.

[edgy lintel]

player.getInventory().setItem(slot,item);

it works very much the same as the inventory api

Thank you .

[edgy lintel]

also to know which number corresponds to which slot check here

[reef delta]

I don't suppose anyone here as worked with GriefPrevention API?

It's absolutely terrible, and really limited- I'm looking to make a command for players to pay each other with claim blocks but I cannot find any accessible methods to both get and set claimblocks for a player.

[tight junco]

that's because the developers behind grief prevention are literally some of the worst ive ever seen

because may i remind you all of this

[reef delta]

I wanna die.

[tight junco]

it is quite literally the worst large scale plugin ive ever seen on code quality

[reef delta]

Makes me want to make a developer friendly fork.

[tight junco]

makes you wanna make an entirely new plugin

[reef delta]

Literally anything would be better

[tight junco]

the plugin could quite literally use Thread#sleep and it'll still be better

he either hates java so much at the same time wanting to make a plugin or he genuinely doesnt even care about oop

[high edge]

I don't care about you

[icy shadow]

me neither

[merry knoll]

oof

[lucid mica]

Anyone know how to make a new playername.yml when a new player joins and load the config if its a player that already joined? then read the config from another class

[high edge]

Get the file, if it exists you'll have contents inside it from the previous join, otherwise write the new contents

[lucid mica]

How would I do that?

[icy shadow]

which bit are you unsure about?

1. check if file exists
2. if exists, read contents
3. if not, write new contents

[lucid mica]

Well I want to make a credit system so you can earn credits by doing something then you can buy stuff with the credits. Just not sure how I would get the file stuff lol to work. Been trying for ages and searched online for help but no luck

[high edge]

Well what do you have so far

[sterile hinge]

(it also sounds like a bad idea to do file IO on the main thread)

[edgy lintel]

hey a quick question
so the word runTaskAsynchronously
It means that the task is asynchronous and on MULTIPLE threads OR
it is really just asynchronous on a single thread as its literal meaning

my educated guess is that it is only on a single thread but idk i dont wanna bother scrolling through nms codes or googling anymore after headaches

pls ping me if you are available for answers, thx. Just wanna verify my guess.

[icy shadow]

runTaskAsynchronously just runs it on a thread that isnt the main thread

if you have a task timer, im not sure if it will always be ran on the same thread every time

probably not

since the scheduler uses a thread pool for async tasks

[edgy lintel]

ok thx a lot! that clears up stuffs!

[merry knoll]

if you want to make sure something is accessed from one thread only, dont use spigot methods

create your own thread and access only using that

[edgy lintel]

like two threads of the same task can be accessing something using spigot methods?

[merry knoll]

two threads of the same task?

i am not sure honestly but i think it uses a pool internally

you would have to check, but i dont think there is a way to guarantee that spigot uses the same thread each time you call an async scheduler

you can guarantee the task inside of the scheduler (only on that instance) is run by one thread though

if thats what you are asking

[edgy lintel]

oh so you are referring to the task not always running on same instance of thread every time from brister?
i understand now
i dont think which instance of thread that accesses or the overhead of spawning new threads would matter tho in my context for now
thx for the tips tho apprecaite it

nvm overhead does matter
thx a lot for the tips plan changed i will be managing the thread myself

[merry knoll]

if you need to access variables from another thread

you either limit the usage of those to one thread

or.. you use atomic type variables (aka thread safe)

second option might be easier if you didnt consider it

[edgy lintel]

oh for that i have atomic reference for the lists and stuffs
idk if the performance will drop tho

[merry knoll]

it wont drop unless the variable is constantly used

[edgy lintel]

oh ok makes sense thx for all your inspiring answers!

one more question tho

[merry knoll]

so if you need to cache data from sql etc, atomic is completely fine

[edgy lintel]

do you think a long async bukkit task gonna slow down the main thread?

[merry knoll]

no, its a separate thread

[edgy lintel]

like relative to a one statement async task, a 1000 statements task will slow down main thread considerably

[merry knoll]

nah, again

when you are using async your main worker continues as normal

[edgy lintel]

oh alr thx a lot appreciate it!

[merry knoll]

only time it can slow down is when you use all resources of your cpu

in which case you have more issues most likely

[edgy lintel]

maybe the issue of the whole pc not the programming then haha

[somber light]

hello, does anyone know if it is possible to tell the maven shade plugin to output the shaded jar in multiple locations?

[lyric gyro]

No

[somber light]

with all due respect your bio made me wonder if antibullying campaigns should be a thing

[broken elbow]

what?

[stuck hearth]

Where's the due respect you offered

All I see is disrespect

[somber light]

¯_(ツ)_/¯

[stuck hearth]

If you're going to be a dick, just say that my guy

[high edge]

with all due respect, your code made me cringe

[lyric gyro]

huh

[somber light]

ok

[broken elbow]

ok guys let's just stop with the very polite insults

[somber light]

aight sorry about it

I'll save frosty the embarrassment by not replying to his comment.

[high edge]

Oh no, whatever will I do now, hide in a hole and cry?

[lyric gyro]

evidently yes

[pulsar ferry]

Lol what

[lyric gyro]

they're just salty i'm happy with myself and wants to ruin the fun for no reason, idk, people are weird

[stuck hearth]

I'm happy for you Emi and I hope you're having a great day 🤗

[lyric gyro]

thank you! i am indeed

[pulsar ferry]

Yeah sad people tbh

[spiral prairie]

Guys

How do you prevent github actions from running when the push is a merge from dependabot?

[stuck hearth]

Pretty sure you can apply exclusions in the script

[dense drift]

looks like you could add if: ${{ github.actor != 'dependabot[bot]' }} before steps

[lucid mica]

Went to sleep, mb. I got the listener for the PlayerJoinEvent, now I just need to create the file stuff lol then read/write to it in different classes

[dusky harness]

Idk about Google 2fa since I don't use it
U can google to see if it syncs tho

If it doesn't then uhh

That's why they had backup codes :/

But besides that until you find your phone u can't get the code

[spring sinew]

i will sync but only show google backups code not discord

[dusky harness]

Also if you lost it, ios and android allows you to track the device

[dusky harness]

Wdym

[spring sinew]

my accout was hacked past month , i will add 2fa for extra security

[dusky harness]

Backup codes are 8 (I think) codes in case u lost ur phone

That u could use

[spring sinew]

yes

[dusky harness]

So u don't have any?

Also note that 2fa is unlikely to prevent you from getting hacked from discord scams

Since it uses token logging which bypasses 2fa

[spring sinew]

i have pc logging , but i will reset pc affter i never can logging discord without bacup code

[dusky harness]

Pc logging?

[spring sinew]

discord pc application

now i use it

[dusky harness]

OK I'll assume u don't have the backup codes

[spring sinew]

but i need to use my new mobile this account

[spring sinew]

yes

[dusky harness]

I mean you can probably lock your phone remotely and see if someone finds your phone

Assuming it's not broken our out of battery

Or*

[spring sinew]

i will check it but not responce

[dusky harness]

Google/Android - find my phone/device
Samsung - either above or Samsung locate phone
Apple - idk

Apple does have one but I think it requires a mac

[spring sinew]

i hve anroid , i will check find my device but i am late

[dusky harness]

Ok

Lock it and make it show a contact phone number

Trying to find it probably will not help depending on the location

[spring sinew]

i will contact my sim coustomer service bt they tell me last location nothing foud enything

[dusky harness]

Wb Google find my device?

Did that work?

[spring sinew]

i think it now reset or remove parts

[dusky harness]

What

Did you lose your phone or did you sell it or smth

[spring sinew]

eny other option to get new backup code ?

[dusky harness]

No

[spring sinew]

lose

[dusky harness]

Then why would it reset

Or remove parts

I mean sure it could've died but Google shows the last location (if location services were on)

[spring sinew]

i think robbers don't have mind

[dusky harness]

Oh u think a robber took it

[spring sinew]

yes it robe

[dusky harness]

Oh then it's done for, but why not check?

Did you check?

[spring sinew]

yes

[dusky harness]

It says phone offline?

[spring sinew]

yes

phone + my bag

[dusky harness]

Oh ur bag too

Ripp

That ls not very good

[spring sinew]

yes

[dusky harness]

Unfortunately if Google doesn't sync 2fa then I don't think you can fix this

And if you do use 2fa in the future remember to write down backup codes

They will most likely give one or more

[spring sinew]

this account i need because this accout old 3 years , and nitro use , my all bussnes i do with this account

[spring sinew]

did you know how to sync 100% working code re sync auth app , eny vedio tuturial or eny way

[dusky harness]

I do not use Google auth

[spring sinew]

[dusky harness]

If you login from a device and discord does not show, ig that means it's not synced

Maybe there is a setting for it

Authy had it disabled by default for example

[spring sinew]

it have only sacn qr code

no another option

[dusky harness]

Alr

[spring sinew]

i cant scan my discord qr need my password , my password is froget , i can't change my password without 2fa

i think my time is not good

[dusky harness]

Do you have anything special linked to ur acc?

If I were you I'd try moving to a new acc asap

So that once u get logged out for whatever reason it's not sudden

[spring sinew]

my nitro and my servers

[dusky harness]

Can u rejoin? And maybe try getting the stuff transfered while you still have access to this account

That's prob the best thing h can do now

[spring sinew]

how to transfer ?

i think you discord devoloper

[dusky harness]

No

Is there a sort of timing safe equals to compare passwords in Java?

[lyric gyro]

timing safe?

sorry, more so the algorithm you'd use to hash passwords ideally should be tuneable in terms of how much time it takes

[spiral prairie]

just use bcrypt

[spiral prairie]

if you forgot your password and dont have your backup codes, i think you will have some trouble getting back
I have a list of important discord tags / server invite links just to be sure if the above methods wont work

[merry knoll]

java gc is good enough to clear circular references right?
