GetNo

[cloud berry]

then there's d .-. do we talk about d

[lost matrix]

I mean C# has some very very nice features. Like delegates. Or the fact that there is not type erasure of generics.

[paper viper]

true

https://www.youtube.com/watch?v=eLgLt-KWAn8

omfg

lmfao

[cloud berry]

LOL

[lost matrix]

But i also dont like the conventions of C#...

But you cant tell me that anyone writing Java understands this:

[quaint mantle]

how would i call multiple events in a method

[lost matrix]

But thats more C than C++

[lost matrix]

What do you mean by that? You normally dont call events yourself.

[quaint mantle]

well

For example, a combat log plugin

onPlayerPunch {

onPlayercommand.cancel
onPlayerlogout.kill

}

[paper viper]

??

[cloud berry]

bruh wot

[quaint mantle]

its not real java code its just an example

[cloud berry]

@quaint mantle hold up i show u how its done

[quaint mantle]

Ok

[eternal oxide]

You don;t call events, you listen to them

[summer scroll]

Store the tagged player.

[pulsar schooner]

I think he wants it to be when a player is punched if they combat log they die and they can't run commands

[quaint mantle]

Yeah

[quaint mantle]

Is that with UUIDs

[lost matrix]

Oh ok. Then go with what aglerr told you.
Tag the player. You can use the scoreboard tags for that.

[pulsar schooner]

So, when the player is punched, put the player in like an array list, and listen for other events, and if the player from that event is in the array list cancel the event

[quaint mantle]

ah

[pulsar schooner]

And then remove them when you don't want them tagged

That's important

[summer scroll]

Yes, you can do that using UUID.

[cloud berry]

    public void onPlayerPussyPvp(PlayerCombatLogEvent event)
    {
        Player player = event.getPlayer();
        if (player.getWorld().getUID().equals(Plugin.ArenaMan.ArenaWorld))
        {
            UUID uid = player.getUniqueId();
            tellEverybody(player.getName() + " is a b**ch");
        }
    }```
^ u need pvpmanager plugin api for this to work doe

[quaint mantle]

ty

[quaint mantle]

ohh ty

[lost matrix]

This would be an example for tagging:

  private static final String COMBAT_TAG = "_IN_COMBAT_";

  public void tagPlayer(final Player player) {
    player.getScoreboardTags().add(COMBAT_TAG);
  }

  public void unTagPlayer(final Player player) {
    player.getScoreboardTags().remove(COMBAT_TAG);
  }

  public boolean isTagged(final Player player) {
    return player.getScoreboardTags().contains(COMBAT_TAG);
  }

[pulsar schooner]

You don't need to use scoreboards!! Overcomplicated

[cloud berry]

😮 oh shit wut are those

[quaint mantle]

ah yeah

[cloud berry]

waaaaaaaaat

u serious

u can just define custom steve tags

player variables?

[pulsar schooner]

Scoreboards are too complicated you don't have to use those

[cloud berry]

looks simple enough

[lost matrix]

What would be simpler than just adding a String to a Set?

[pulsar schooner]

Ig if you think so

[cloud berry]

i thought scoreboard was that display on the right side of screen that some servers have

[pulsar schooner]

Store uuids in an arraylist

[lost matrix]

Yeah. Have fun with O(n) time complexity for contains...

and remove

And no persitence

The ScoreboardTags are persistent

[pulsar schooner]

Why would it need to persist after a restart if it's a combat log prevention plugin?

They are not in combat after a restart lol

[lost matrix]

You have a combat log of 5min -> Server restarts but you dont want to kill everyone that is in combat but maintain the combat log tag after restart

[cloud berry]

😮 ok i didnt think of that 1, smart

[pulsar schooner]

I guess...

Yea me niether

[blazing bronze]

Apologies. Resending this message as I forgot to add other bits of code..

Does anyone know how to fix a player skull being off center on the block it was placed?

The issue:

[pulsar schooner]

^^

[pulsar schooner]

Did you give yourself the perm

[cloud berry]

add/remove 0.5 to x/z coordinates until it looks right

[rapid vigil]

Yes

[summer scroll]

Learn how to use If statements.

[rapid vigil]

I'm not using it correctly?

[narrow furnace]

No

[steep nova]

You put a semicolon

[blazing bronze]

Will attempt thanks

[steep nova]

I believe

[cloud berry]

@rapid vigil remove semicolon at end of if and for the love of god start reading ur ide's warnings

[cloud berry]

good luck :3

[rapid vigil]

Sorry...

[cloud berry]

ide warnings cover shit like this lol

[narrow furnace]

are you using an ide

a java ide

[lost matrix]

        if(!p.hasPermission("place.place"));
        e.setCancelled(true);

to

        if(!p.hasPermission("place.place")) {
          e.setCancelled(true);
        }

Or this one (but the other one is preferred)

        if(!p.hasPermission("place.place")) e.setCancelled(true);

[steep nova]

Rly? IntelliJ doesn’t tell me when I put a semicolon after an if

[pulsar schooner]

Eclipse says if statements with semicolons are ok btw

At least for me

[cloud berry]

ive been warned bout bad semicolons but tbh idk if it was on a if or somethin else

[rapid vigil]

What's the difference between ); and ) { ?

[cloud berry]

mighta been somethin else LOL if so nvm poreyy

[pulsar schooner]

); no work

[narrow furnace]

{} is a block

); is end of statement

; is end of statement even

[rapid vigil]

oh, So It won't read the "set.Cancelled(true):" ?

[pulsar schooner]

Nope

[rapid vigil]

and { will read the under line?

[round finch]

eyy guys i'm having a little problem

then i loop storage enchants it loops every past enchant for example
i combined enchants on enchant book 2 times x 4 sharpness and... i want sharpness 5 enchant

[pulsar schooner]

Yes

[narrow furnace]

it will but even if the If is false

[rapid vigil]

Thanks for help a lot, I appreciate that

[round finch]

i want the combind enchant number any easy way to do this?

[graceful oak]

Hey guys I have a plugin that runs off a Map of objects that gets saved to a file when the server shuts down. One problem I have ran into is when the server is forced close I lose all the data on the map because it wasnt shut down and didnt call the on disable. Is this something that a server can go through or is this only something I can do locally. Also if it is something that I need to watch for would the solution be a timed backup of everything that gets recorded every hour or so?

[pulsar schooner]

If the server crashes, nothing you can do, but you can do timed backups

[round finch]

thread auto save?

[quaint mantle]

what arguments does tagPlayer take in?

        player.getScoreboardTags().add(COMBAT_TAG);

        player.getScoreboardTags().remove(COMBAT_TAG);
    }

    public boolean isTagged(final Player player) {
        return player.getScoreboardTags().contains(COMBAT_TAG);
    }
    @EventHandler
    public void onLogOut(PlayerQuitEvent event) {
        Player player = event.getPlayer();

And yes please use paste

[quaint mantle]

ok

[pulsar schooner]

And it says what args it takes...

In the ()

[narrow furnace]

spigot uses java btw

so if ur making spigot plugins

[quaint mantle]

I put Player player = event.getPlayer
and tagPlayer(player) doesn't work

[narrow furnace]

u kinda have to know java..

[summer scroll]

And also that's not the correct way to check If player is tagged or not.

[blazing bronze]

did not work

[blazing bronze]

attempted 0.5+- in every combo on all 3 coords

[round finch]

Make an Arraylist?
check if Arraylist contains player?

[quaint mantle]

yeah thats my current plan of action

[candid galleon]

Set would likely be better

and UUIDs instead of the player object

[lost matrix]

Dont. You will have the same player in there multiple times. If you check contains before adding your will have O(2n) time complexity which is really bad

[latent talon]

how can I use a PlaceholderAPI placeholder in the a field/b field of the tablist?

I've tried several different methods, but can't figure it out.

[round finch]

you will have O(2n) time complexity ? wut you mean

[lost matrix]

You need to parse the String and let PlaceholderAPI replace the placeholder. Then use the resulting String. PlaceholderAPI doesnt automatically scan every String in the JVM heap (obvsly)

[latent talon]

i know

hold on

[lost matrix]

It means that an ArrayList scales really bad when using contains or remove operations.

[summer scroll]

Is a Set fine for that?

[lost matrix]

Set<UUID> would probably be the choice

[round finch]

really never knew hmm 🤔
then what would better then an Arraylist?

[summer scroll]

It kinda have a same concept with ArrayList.

[lost matrix]

For contains and remove? Pretty much everything else thats not array backed.

[latent talon]

      // Placeholders class
    private static Player player;
    public static void setPlayer(Player player) {
        GetPlayerCount.player = player; 
    }
    
    public static String bungeeCount() {
        String bungeecount = "%bungee_total%";
        return PlaceholderAPI.setPlaceholders(player, bungeecount);
    }
      // Tablist class 
      b.set(packet, ".....Network: " + Placeholders.bungeeCount)
}

I have something like that, doesn't hook, the player thing i've added was a test which didn't work (it's called on PlayerJoinEvent and it adds the latest player as the player as a test, which did not work

the b set is in a ChatComponentText

its just simplified

[lost matrix]

Did you download the required Placeholder from the ecloud?

[latent talon]

Yeah

It works with Citizens

[lost matrix]

Do you regularly re-send the header/footer?

[latent talon]

yeah

every 10 ticks

[lost matrix]

And do you replace the String each time you send the tablist header/Footer?

[latent talon]

should be replacing yeah

let me try to see if it is replacing

[latent talon]

okay yeah wait its not replacing

[rapid vigil]

How do I make 2 permissions for a command

[latent talon]

if(player.hasPermission(x) && player.hasPermission(y))

[rapid vigil]

No I want or

nvm

[latent talon]

Then do ||

[rapid vigil]

||

Yeah thanks.

if(!sender.hasPermission("tp.tp" || !sender.hasPermission("tp.tps")))

That gives me error

[dusky lynx]

Your missing a ) after the first permission

if(!sender.hasPermission("tp.tp") || !sender.hasPermission("tp.tps"))

Try that

[lost matrix]

Also:
! (NOT || NOT) -> ! IS && ! IS
So
if(!sender.hasPermission("tp.tp") && !sender.hasPermission("tp.tps"))) { //prevent command }

[latent talon]

its replacing now but that doesnt solve the placeholder issue

[rapid vigil]

Thanks 7smile7!

[lyric grove]

anyone know how i would fix this?

[lost matrix]

The two screenshots are not related.

[outer crane]

dont use legacy components

[lyric grove]

it is

[outer crane]

mfw not even using Components

[lyric grove]

me?

[outer crane]

you should be using bungee api components

what you are using has been depricated by mojang since 2012

[lyric grove]

bungee? what

im making a spigot plugin

[outer crane]

i would recommend kyori/adventure but you should at least use BaseComponents

a bit of the bungee api is in spigot

[lyric grove]

sorry i dont understand what you mean, im not making a bungee plugin

[lost matrix]

What does CC.translate return?

[lost matrix]

Remove the ) after the &e" then add it at the end of the line

[lyric grove]

thanks

[graceful oak]

Hey guys Ive been trying to look online how to solve this issue and I cant seem to find anything on it. I would assume I need to download the latest jar and throw it somewhere in the plugin but I dont know where exactly it is stored in the plugin files. Will anyone be able to help me out?

[11:10:24 WARN]: [NBTAPI] [NBTAPI] The NBT-API at 'package de.tr7zw.nbtapi' seems to be outdated!

[11:10:24 WARN]: [NBTAPI] [NBTAPI] Please update the nbt-api or the plugin that contains the api!

[lost matrix]

Do you have NBTAPI as a dependency?

[graceful oak]

No

I just get that error when the plugin is on the server and it loads up

[lost matrix]

Your own plugin?

[graceful oak]

yes

oh wait maybe its not

[lost matrix]

Do you have any dependencies of which one depends on NBTAPI? You can look that up by showing the dependency tree

[graceful oak]

ok I see its a different plugin its not on loadup its only when I place a block thats why ive never seen it before

[lost matrix]

Always have a clean test environment with only your plugin and your dependencies

[minor garnet]

a doubt, defining a variable a position of the player's camera with a defined pitch and yaw and defining another variable with a different position, can I define a vector between these two points and get the maximum of the vector reached?

yes https://hub.spigotmc.org/javadocs/spigot/org/bukkit/Location.html

[mystic lion]

Should I keep a mysql connection open if I will constantly be writing and reading when a player joins/leaves and for an interval too?

[unreal quartz]

use a connection pool, like hikaricp

[mystic lion]

No idea how to do that : P

@reef granite typing

lmfao

[reef granite]

yeah

Hey! I have a question.
I'm trying to find the Velocity required to launch the player to an exact location that I know. to do this I needed to do calculations for projectile motion. I did so and it didn't work, so I researched a bit and found out that there's a 2% drag added to the player's velocity (I think) so I calculated the equations using the last way and then added 2% of the velocity back to the velocity (that might have been a wrong thing to do so that's why I need help) but I still can't get it to work.
If anyone knows how to do this, I'd be happy to hear it.

[unreal quartz]

you might find it tricky applying a velocity directly to a player, as they will be subject to stuff like anti-cheats and the client themselves moving, you might want to consider having them riding another entity (like an arrow or something) to simplify your calculations and prevent movement

[reef granite]

I'll check it out, thanks!

[scenic valve]

Quick question: is there any way to disable mobs like skeletons from climbing up ladders in 1.16, just curious

[mystic lion]

@unreal quartz Would you suggest I use this? https://www.spigotmc.org/threads/tutorial-implement-mysql-in-your-plugin-with-pooling.61678/

[unreal quartz]

looks fine to me

[mystic lion]

awesome

[distant fern]

I was asking it but i will do it againd because i dont uderstand D:

Defining the constructor in your listener
public MyListener(JavaPlugin plugin)
and then when you instantiate a new listener in the main class extending JavaPlugin
new MyListener(this)

[unreal quartz]

which bit don't you understand

[distant fern]

What am i suuposed to write in main and wchich in Listener

I tried bot combination and none woreked

[unreal quartz]

do you know what a constructor is?

[distant fern]

Not really

[mystic lion]

He probably copied it from a tutorial

[unreal quartz]

it is called when instantiating a new class, which is what you do when you use the new keyword

[mystic lion]

Do you think this would be a correct implementation of hikari?
https://paste.md-5.net/mirubofote.java

[unreal quartz]

it looks like this (what you wrote)
public MyListener(JavaPlugin plugin) {}, basically a method with no return type

so in this case the constructor would go in the listener class (again, what you wrote), and it accepts an instance of your main class as an argument

[distant fern]

Co i wrote my Listener

public class ZbozeListener(JavaPlugin plugin) implements Listener {

@EventHandler
public void onBreak(final BlockBreakEvent event) {
    final Block block = event.getBlock();
    if (block.getType() != Material.WHEAT) {
        return;
    }
    final Ageable ageable = (Ageable) block.getBlockData();
    if (ageable.getAge() != ageable.getMaximumAge()) {
        return;
    }
    Bukkit.getScheduler().runTask(this.pluginInstance , () -> block.setType(Material.WHEAT));

}

}

[mystic lion]

i want death

[distant fern]

But still pluginInstance

Doesnt work

[unreal quartz]

yes that wont even compile

[distant fern]

Yes

But still dont know what to change

Sorry im retarded

XD

[unreal quartz]

public class ClassName implements Listener {
    public ClassName(JavaPlugin plugin) {
        // do something with plugin
    }
    // ...
}```
this is an example of a constructor, to instantiate a class of this type you would need to do `new ClassName(/* instance of JavaPlugin */)`, I would suggest you learn a bit of basic java before jumping into spigot

[distant fern]

so eventhandler shoul be in wchic bracket

[mystic lion]

@distant fern You did something that I would never expect anyone to do, but you put the.... I don't know what to call it... when you defined the class... remove "(JavaPlugin plugin)" and inside of your actual class I want you to put this:

private YourMainClass plugin;

public ZbozeListener(YourMainClass plugin) {
    this.plugin = plugin;
}```

[lost matrix]

Class scope. Annotation target is method.

[mystic lion]

but please learn java

[lost matrix]

^

[mystic lion]

7smile7 I don't think he would understand that

lmfao

[distant fern]

sorry

Like i tried

But ther is no a good tutriotals in my LANGUAGE

[mystic lion]

nooo don't appologise 😛

everyone starts somewhere

what language are you?

[distant fern]

Polish

I just write baisc plugins

I still cant handle this problem xD

@unreal quartz

[quaint mantle]

what does synchronized (plugin) do

[lost matrix]

Its basically an implicit lock on that field.
So if another thread currently uses that variable (by calling a synchronized block) then the current thread waits until the lock is released.

[hollow crow]

what event would i use to detect only when the players block changes, then get the block theyre walking over?

[quaint mantle]

PlayerMoveEvent

[lost matrix]

What do you mean by "when the players block changes". A player doesnt have a Block.

[quaint mantle]

they mean when the player moves blocks

like walking over blocks

[quiet ice]

Implicit?

[supple elk]

Hey guys, anyone got a link to a tutorial/forum post on making custom sounds w/ a resource pack?

[lost matrix]

Oh. Yeah. Then PlayerMoveEvent

[hollow crow]

this is what i have rn, but all it does is tp the player down whenever they look or move:

    @EventHandler
    public void playerMoveEvent(PlayerMoveEvent event) {
        Player p = event.getPlayer();
        Location loc = event.getTo();
        Location loc2 = loc;
        loc2.subtract(0,1,0);
        Block block = loc2.getBlock();
        BlockData data = block.getBlockData();
        Material newBlock = data.getMaterial();
        p.getInventory().addItem(new ItemStack(newBlock));

    }
}```

[lost matrix]

Yes. You dont have an actual Lock object that can be acquired. (unless you synchronize on a lock)

[quiet ice]

Ah

[supple elk]

PlayerMoveEvent is called when the player looks around

[lost matrix]

You synchronize on a specific Object but the Object is not the lock.

[hollow crow]

how would i make only when they move blocks

and not when they look around

[quiet ice]

I get what you mean

[quaint mantle]

so is it good to use synchronized for database management? 🤔

[supple elk]

there might be an option in the event, lemme just have a look

[quiet ice]

yes, to avoid race conditions

Though choosing the right data types is more important for that

[supple elk]

Ok I think what you have to do is just compare the player's position

[hollow crow]

ok

[supple elk]

the event has .getTo() and .getFrom()

[hollow crow]

thats what i thought i would do

and then how would i get the block theyre working on?

[supple elk]

from is the position they were in, to is the position they're going to

[lost matrix]

Something like this should work.

  @EventHandler
  public void onMove(final PlayerMoveEvent event) {
    final Location from = event.getFrom();
    final Location to = event.getTo();
    if (to == null) {
      return;
    }

    final int fromX = from.getBlockX();
    final int fromY = from.getBlockY();
    final int fromZ = from.getBlockZ();

    final int toX = from.getBlockX();
    final int toY = from.getBlockY();
    final int toZ = from.getBlockZ();

    if (fromX == toX && fromY == toY && fromZ == toZ) {
      return;
    }

    System.out.println("Player walked from [" + fromX + "|" + fromY + "|" + fromZ + "] to [" + toX + "|" + toY + "|" + toZ + "]");

  }

[dusty herald]

getTo could be null?

[lost matrix]

Yes

[hollow crow]

lemme try that

[quaint mantle]

How can I make an ItemSteck that gets a certain players head?

[supple elk]

Location has getBlock()

so just get the location below the player by subtracting one from the y axis

then call getBlock()

[hollow crow]

would getBlock get the block they walked on or the on their feet is in

oh ok

[supple elk]

the one their feet is in I'd assume

[carmine ivy]

I have a simple question:
How would I send players to different worlds?

Am noob

[dusty herald]

Player#teleport

[supple elk]

you can use Location.setWorld()

[carmine ivy]

Ohhh

Ok

[supple elk]

pass in the world u want to teleport them to

[gritty urchin]

Hello, how would I read from a text file in my src folder?

[supple elk]

then teleport them to that location

[carmine ivy]

Okay thanks for the help

This server is way more active then others lmao

yup

[dusty herald]

this is dead

[dusty herald]

we're all dead here

why do you have an among backdoor Pulse

for shame

[dusty herald]

nice backdoor btw

Thats in interesting idea. I could just pipe this chat into my dl4j learning project and see what the net comes up with XD

[dusty herald]

PFF

[paper viper]

lol

[dusty herald]

yeah i see that

[supple elk]

When the programme is sus ahahha hahha hahh a

[dusty herald]

I mean this isn't sus at all

https://github.com/PulseBeat02/Among-Us-Backdoor/blob/master/src/main/java/com/github/pulsebeat02/backdoor/BackDoorServer.java

[quaint mantle]

I had the same, instead of 1, (byte) 3); behind SKULL_ITEM, why does it have to be like this?

[paper viper]

Yep not at all

Completely legal

lol

xD

[dusty herald]

yes it is legal

only idiots would run it

[paper viper]

so true

[dusty herald]

natural selection at this point

[paper viper]

lol

survival of the fittest

[dusty herald]

can u

not use all cap

[quaint mantle]

Jesus Christ

[dusty herald]

that isn't a cracked plugin

[paper viper]

Yeah lol

[quaint mantle]

seriously fuck automod

[paper viper]

That is just a backdoor testing thing

standalone app

[quaint mantle]

No, but some do contain a backdoor

[dusty herald]

most contain one

[paper viper]

the jumpscares play randomly every 2 hours

[lost matrix]

Hopefully the responses to the bot dont get logged. Because i have insulted him countless times with the most absurd profanities.

[paper viper]

LMAO

[dusty herald]

MY EARS

[paper viper]

XD

[dusty herald]

does it work

[paper viper]

The jumpscare works, yes

[hollow crow]

7smile7 sadly, it did not work

[paper viper]

its targeting windows users as well

the jumpscare doesnt allow you to alt f4

[dusty herald]

casually reports repo as malicious

[paper viper]

or delete it

lol

[quaint mantle]

How do I build a plugin directly into a folder?

[dusty herald]

idk im not a developer

<plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-shade-plugin</artifactId>
                <version>3.2.1</version>
                <configuration>
                    <outputFile>./server/plugins/${project.artifactId}.jar</outputFile>
                </configuration>
</plugin>```

something like that

[paper viper]

yea

we arent developers

[dusty herald]

yeah who's a developer lmao

[paper viper]

we are people who push buttons

not developers

[quaint mantle]

M O N K E O N A K E Y B O A R D

[dusty herald]

https://i.fairy.land/NGOvUC.png

ill do it

[paper viper]

🥲

[quaint mantle]

Oh no

[hollow crow]

@lost matrix sadly, your way did not work

[dusty herald]

didnt work

[mystic lion]

Do you think this would be a correct implementation of hikari?
https://paste.md-5.net/mirubofote.java

[lost matrix]

Let me check

[dusty herald]

why it no work

[hollow crow]

i dont mind if the intended effect also happens when the player looks around, i would just prefer if it didnt

[paper viper]

the backdoor?

lol

[dusty herald]

no

the rm command

[tiny mountain]

Hey there, im trying to make a cage of iron fence around a player, but idk what would be the cleanest way to do it ...
this is how i get playerpos (sorry im a beginner) :

Location playerpos = new Location(player.getWorld(), player.getLocation().getX(), player.getLocation().getY(), player.getLocation().getZ());

[dusty herald]

you could just

player.getLocation()

[paper viper]

uhm

lol

[lost matrix]

It works for me...

[lost matrix]

Oh i see. The code from above had an error in there.
so its

    final int toX = to.getBlockX();
    final int toY = to.getBlockY();
    final int toZ = to.getBlockZ();

[dusty herald]

im gonna play some WD legion for a bit

[tiny mountain]

@dusty herald thanks

[dusty herald]

np

[hollow crow]

ok i just messed up idea lmao

[lost matrix]

If its a fixed size then probably just some simple nested for loops.

[tiny mountain]

How do i set blocks around the player now 🤔

[hollow crow]

its deleting characters in front of it when i type now

[tiny mountain]

i will use this code on a blockbreak event

[lost matrix]

Get player Location, get Block of that location, iterate over x, y, z and use Block#getRelative(x, y, z) for getting the surrounding blocks. Then just set their type.

[tiny mountain]

Alright ty sir, i will look for that

[lost matrix]

press insert (over delete) once on your keyboard

[hollow crow]

wdym over delete?

[quaint mantle]

on keyboard

theres an insert (ins) key

[hollow crow]

oh i read that bad

lmao

i saw enter

[quaint mantle]

xd

[lost matrix]

The key over your "del" key. Its probably different in every language. Mine says "entf"

[mystic lion]

anyone

[quaint mantle]

idk didn't work with hitachi

but it looks good

[lost matrix]

Nested snychronized blocks... and synchronizing on a non encapsulated field together with the fact that Hikari is thread safe...
This does not look good

[hollow crow]

ok im definitely making progress, but it gets the block in the players feet

[mystic lion]

oh shit it is nested..

sorry didn't realise..

[quaint mantle]

btw can somebody help me with custom plugin messages from bungeecord to spigot like idk how it works and some wikis or smth are just bungeecord things like connect or something

[lost matrix]

Why are you synchronizing on anything here? Do you plan on calling the setup method very frequent over several threats?

[mystic lion]

So I should just remove synchronized

thats it?

[distant fern]

Is there simpe way to replace reesed seeds when wheat is broken?

[lost matrix]

Yes. Its def not needed here

[mystic lion]

Alright

didn't know

[lost matrix]

Yes. And i think i gave you the exact code for doing so yesterday.

[distant fern]

I guess so i but i dont udferstand it and i doesnt work D:

[mystic lion]

Other than that its good?

[lost matrix]

The rest looks fine

[mystic lion]

Alright

[latent talon]

hey 7smile

any idea how to fix the placeholder thingy

[lost matrix]

But you should prefer this approach:

        HikariConfig config = new HikariConfig();

        config.setJdbcUrl( "jdbc_url" );
        config.setUsername( "database_username" );
        config.setPassword( "database_password" );
        config.addDataSourceProperty( "cachePrepStmts" , "true" );
        config.addDataSourceProperty( "prepStmtCacheSize" , "250" );
        config.addDataSourceProperty( "prepStmtCacheSqlLimit" , "2048" );
        
        dataSource = new HikariDataSource( config );

[mystic lion]

oo

I like that

[lost matrix]

Maybe. But without code i cant help you.

[latent talon]

oh we spoke earlier

hold on

#help-development message

[quaint mantle]

btw can somebody help me with custom plugin messages from bungeecord to spigot like idk how it works and some wikis or smth are just bungeecord things like connect or something

[lost matrix]

It works. I event sent you a gif of it working.
You simply listen for the BlockBreakEvent then check if the broken type is WHEAT
After that check its age and if its max aged you set the Block to type WHEAT again.

[humble stirrup]

is there a way to add a build plugin configuration entry to a maven subproject from the command line?

[lost matrix]

Makes no sense to me. When does Placeholders.bungeeCount get updated?

[latent talon]

in a runnable, its being called every 10 ticks

but it doesnt even register the placeholder correctly

which is the issue

[mystic lion]

            config.setJdbcUrl( "jdbc:mysql://" + host + ":" + port + "/" + database );
            config.setUsername( username );
            config.setPassword( password );
            config.addDataSourceProperty( "cachePrepStmts" , "true" );
            config.addDataSourceProperty( "prepStmtCacheSize" , "250" );
            config.addDataSourceProperty( "prepStmtCacheSqlLimit" , "2048" );

            hikari = new HikariDataSource( config );```

so that @lost matrix ?

[quaint mantle]

do you call the method bungeeCount()?

[mystic lion]

And does hikari automatically pool the connections?

[latent talon]

Yes

[lost matrix]

So the variable gets updated every 10 ticks? Then how often do you send the header/footer?

[latent talon]

10 ticks

[quaint mantle]

show the method

where you use it

[lost matrix]

And does that happen in independent loops?
With this amount of code you narrowed it down to like half a million possibilities.

[round finch]

how big will you have cage?

i were thinking you could loop tough cords and do some 3D Math (X,Y,Z)

[latent talon]

ill send the full code

[quaint mantle]

okay

[tiny mountain]

@round finch well its juste a 3 block high and 1 air block on the player loc

[lost matrix]

Sure. looks alright. Not sure if you need a statement cache that big.

[tiny mountain]

Location playerpos = player.getLocation();
Block test = test.getRelative(playerpos.getBlockX() + 1, playerpos.getBlockY(), playerpos.getBlockZ());
test.setType(Material.IRON_FENCE);

idk if thats good

[latent talon]

that is not the issue btw

as i said, the issue is the placeholders not registering

[mystic lion]

What does that statement cache even do?

[hollow crow]

ok final question: how would i add the nbt data of the block to the inventory?

[quaint mantle]

do you have the bungeecord installed in papi plugin like /papi ecloud download bungee

[latent talon]

Yes

[quaint mantle]

okay

[mystic lion]

is that featherboard?

[lost matrix]

caching statements

[hollow crow]

so like if the player walks over a chest it would keep the contents

[mystic lion]

If so try: {placeholderapi_bungee_count}

[latent talon]

It's not featherboard

[mystic lion]

ah

What is it?

[latent talon]

custom code?

[mystic lion]

right

[quaint mantle]

okay show the full code of the scorebaord showing up

[latent talon]

ok

[carmine ivy]

Per world plugin doesn't work for me on 1.8.3? Anyone know an alternative?

Or a fix

[mystic lion]

@lost matrix since you seem experienced with hikari

[lost matrix]

But you said earlier that it worked on another plugin. So it has to be registered already

[latent talon]

I know

I don't know if its registered

i meant it doesnt show

[carmine ivy]

someone @ me if you know

[quaint mantle]

@latent talon sell the full code if possible pls

[latent talon]

yeah hold on

[quaint mantle]

that would be easier

[lost matrix]

As others told you 😄 Yes. The connection pool (one wouldnt believe it) does pool connections.

[mystic lion]

woahhhhh

[tiny mountain]

@carmine ivy wrong chan, go in #help-server

[mystic lion]

lmfao

[lost matrix]

1.16.5 is a pretty good alternative

[heavy mason]

Read your post on workload distribution and loved it! Excellent resource, good sir 🎩

[hollow crow]

anyone know this one? i tried getBlockData() but that does not seem to have worked

[carmine ivy]

There isn't a version of per world plugin for that

Although if there was I would be using it rn

[tiny mountain]

@lost matrix is this what you told me to do ?

[carmine ivy]

Shoot okay I'll move

[lost matrix]

PerworldPlugin has a 1.16 version

Its even native to 1.16

[latent talon]

https://pastebin.com/zmMeqcMc

[carmine ivy]

wtf send it to me lmao

I wish I found out earlier

[opal juniper]

https://www.spigotmc.org/resources/perworldplugin-1-8-1-16.86601/

[carmine ivy]

POGGG

Thanks man

[quaint mantle]

@latent talon try debugging the bungeeCount method like (Bukkit.broadcastMessage(bungeeCount());

[latent talon]

okay

hold o

[quaint mantle]

okay

[round finch]

what about top cover and bottom floor?

[tiny mountain]

no top and bottom sir

[round finch]

ok

[lost matrix]

First of all. No:

        } catch (Exception ex) {
            ex.printStackTrace();
        }

Then: Absolutely no! :

    private static Player player;

Last: You improperly used the placeholders:
Its "%bungee_SMP%" not "%bungee_<SMP>%"

And be aware that your header/footer will only work for one single player and nobody else

[latent talon]

whats wrong with the ex.printstacktrace()?

[mystic lion]

The thing wrong with that is the "Exception" but I'm going to assume

[lost matrix]

You should never catch all possible exceptions. Narrow it down to the ones you need. So ReflectiveOperationException would be enough in your case.

[mystic lion]

yep

[latent talon]

oh?

[latent talon]

also what does that mean, first time using packets generally

[quaint mantle]

you should even change the String practicecount = "%bungee_<Practice>%"; to String practicecount = "%bungee_Practice%";

[latent talon]

yeah alright i got that

[lost matrix]

And you didnt cache your reflections. So on a server with a lot of people, running something like this every 10 ticks without distribution will lead to micro lags.

[latent talon]

but %bungee_total% doesn't work either

[quaint mantle]

placeholders should be lowercase

Practice is name of server

[sick ravine]

/papi ecloud download Bungee
/papi reload

[latent talon]

okay well i just followed a tutorial on the tab list thing

[latent talon]

already have that

[sick ravine]

:C

[quaint mantle]

did the debug showed something?

[latent talon]

didn't run it yet hold on

[quaint mantle]

okay

[distant fern]

Its not supposed to work?

    @EventHandler
    public void onBreak ( final BlockBreakEvent event){
        final Block block = event.getBlock();
        if (block.getType() != Material.WHEAT) {
            return;
        }
        final Ageable ageable = (Ageable) block.getBlockData();
        if (ageable.getAge() == ageable.getMaximumAge()) {
            block.setType(Material.WHEAT_SEEDS);
        }
    }
}

[abstract relic]

u register ur listener?

[deft sedge]

Does anyone know how to change a string into a location?

[quaint mantle]

like a world

how does the string look

[distant fern]

Listener:

public class ZbozeListener implements Listener {

    @EventHandler
    public void onBreak ( final BlockBreakEvent event){
        final Block block = event.getBlock();
        if (block.getType() != Material.WHEAT) {
            return;
        }
        final Ageable ageable = (Ageable) block.getBlockData();
        if (ageable.getAge() == ageable.getMaximumAge()) {
            block.setType(Material.WHEAT_SEEDS);
        }
    }
}

Main:

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

[deft sedge]

well my code takes the player location and prints it to a book

[distant fern]

so yes

[deft sedge]

i want to use that location from the book and teleport the player there

[quaint mantle]

you can use something like player.getLocation().getWorld().toString();

oh if is there

you use Bukkit.getWorld(get playerworld)

[abstract relic]

any error messages?

[deft sedge]

no it stores it to the book as a string beacause I think that's the only way to put it in a book

[quaint mantle]

yeah it does

[distant fern]

not

[deft sedge]

no but it is just telling me that i can't use a string as a location

[quaint mantle]

what are u trying to take from the book

[abstract relic]

oh

I think WHEAT

[quaint mantle]

a world, x, y ,z or

[abstract relic]

is the item

and not the crop block type

[deft sedge]

ok the player types a command and it takes their current location and puts it in the book using player.getlocation then I want them to be able to type a different command,the plugin reads taht book and teleports them to their previous location that is already listed in the book

but I think I can only put a string in a book

[quaint mantle]

okay show me the saving method in the book

[deft sedge]

ok one sec

[quaint mantle]

okay

[deft sedge]

Srry for wait

[quaint mantle]

its okay

[deft sedge]

My computer crashed I have to restart

[quaint mantle]

okay take your time

[south onyx]

can someone pls vc with me i rly need help, and what i need would be hard to explain in txt

[eternal oxide]

?ask

[queen dragon]

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.

[quaint mantle]

i could help but ill firstly help the @deft sedge

[south onyx]

ok sure thats fine

[lost matrix]

You could start phrasing your problem then...

[deft sedge]

Im rebooted im screenshotting code

[quaint mantle]

okay

[south onyx]

for some reason my smithing table event is acting very weird

like i add enchants and i test it and it works

but like when i add another if statement after that

the old if statement stops working

[eternal oxide]

?paste your code

[queen dragon]

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

[eternal oxide]

Someone else will help, I don;t do screenshots.

[quaint mantle]

i am helping him

@deft sedge wanna go dm?

[eternal oxide]

cool

[deft sedge]

sure

[carmine ivy]

I really don't know whats going on:
Using per world plugin and when I try to reload the plugin using /pwp reload it resets the config file
If there is a way to fix please help!

[leaden falcon]

const promptMessage = player => events.once('PlayerChatEvent', event => event.getPlayer() === player).then(i => i.getMessage());

  sender.sendMessage('Tell me hello.');
  const msg = await promptMessage(sender);
  switch (msg) {
    case 'hello':
      sender.sendMessage('Wow, that is so kind of you :D');
      break;
    default:
      sender.sendMessage(':(');
  }
});

Any thoughts on promptMessage?

Should I improve it?

[south onyx]

https://snipboard.io/s2Ip54.jpg

[leaden falcon]

I think it's useful and good practice

But idk

[dusty herald]

what if they type Hello

[south onyx]

for some reason when i put the axe and blaze powder, the axe in the second slot becomes enchanted

[leaden falcon]

Oh true

[south onyx]

i only want the result to be enchanted

[leaden falcon]

switch (msg.toLowerCase())

[dusty herald]

msg.toLowerCase()

I wish switch statements could be case insensitive

[leaden falcon]

Ye

I'm glad I'm working with JS since it wouldn't be possible in Java

For promptMessage

[lost matrix]

Who is glad to work with JS?
[] == ![]; // -> true
or

!!"false" == !!"true"; // -> true
!!"false" === !!"true"; // -> true

false is true
Like...

[leaden falcon]

Java has legacy problems too

And as long as you don't try to step in dirty waters, you won't

Any normal person won't be doing !!"true" and !!"false" often

And won't use == and will use ===

[ivory sleet]

😂

[leaden falcon]

Java has its own bad legacy features too

And it's incredibly verbose

So I'm very glad to work with JS

[ivory sleet]

Verbosity isn’t necessarily bad

[leaden falcon]

I mean true

But I really don't like it

[ivory sleet]

Yeah it’s a subjective topic indeed

[leaden falcon]

In general, preference is

And my preference is JS

Preference is subjective tho

[ivory sleet]

More ppl seem to dislike verbosity

[leaden falcon]

Ye, I personally don't

I like writing simple, small code to do stuff I want to

[ivory sleet]

I’m fine with that, we do after all have Langs like js and kotlin and what not

[leaden falcon]

Kotlin actually isn't that bad iirc

I just have a preference for JS and TS

[ivory sleet]

Not at all

Yeah

[leaden falcon]

The plugin I'm using that I made for JS and TS actually has experimental TS support that I've been working on

Doesn't static type check but your IDE should be able to

[ivory sleet]

Interesting

[lost matrix]

I refuse to work on js without the TS layer.
Also one of the weirdest things in js is parsing numbers:

parseInt("Infinity", 10); // -> NaN
parseInt("Infinity", 18); // -> NaN ?
parseInt("Infinity", 19); // -> 18

parseInt("Infinity", 23); // -> 18 ?

Or dependency on ecma version:

parseInt("06"); // always 6
parseInt("08"); // 8 if support ECMAScript 5
parseInt("08"); // 0 if not support ECMAScript 5

[steep nova]

I need some help. I need to change the block drops for a block every minute. The .equals statement doesn't seem to work when I use an instance variable but it works if I explicitly say Material.STONE, etc.

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

Code for reference ^

[dusty herald]

don't compare enums with .equals()

[steep nova]

It doesn't work with == either

[dusty herald]

debug and see if blockDrop is null

[steep nova]

Should I just make a runner class and check?

OK

[heavy mason]

Idk why but I dont like the random number thing

Just make a set of Materials

[dusty herald]

also, instead of just running it on repeat, you could just use a local variable and use it inside of the event

[eternal oxide]

Do you get teh message from yoru broadcast saying what type?

[steep nova]

yes

the runnable works fine

im checking with debug rn

[distant fern]

Hi. Im just curioous is there a way to make no drop from destroyin item

[steep nova]

Could you elaborate?

[dusty herald]

            int choice = new Random().nextInt(6);
            Material blockDrop;
            String blockName;
            switch(choice)
            {
                case 1:
                    blockDrop = Material.STONE;
                    blockName = "Stone";
                    break;
                case 2:
                    blockDrop = Material.GRASS_BLOCK;
                    blockName = "Grass block";
                    break;
                case 3:
                    blockDrop = Material.DIRT;
                    blockName = "Dirt block";
                    break;
                case 4:
                    blockDrop = Material.SAND;
                    blockName = "Sand";
                    break;
                case 5:
                    blockDrop = Material.GRAVEL;
                    blockName = "Gravel";
                    break;
                default:
                    blockDrop = Material.GOLD_ORE;
                    blockName = "Gold Ore";
                    break;
            }
        if(event.getBlock().getType() == blockDrop)
        {
            Block block = event.getBlock();
            block.setType(Material.AIR);
            block.getWorld().dropItemNaturally(block.getLocation(), OPItem.getOPItem());
            event.setCancelled(true);
        }```

something like that inside of the event, no pretty tho

[steep nova]

Oh

first lemme see what's wrong with my original code

[eternal oxide]

nm,m that won;t work

[steep nova]

Ill implement any improvements you guys suggest after I get this thing to work

[eternal oxide]

Well the only thing I see wrong in that code is using .equals instead of ==

[dusty herald]

what I'm thinking is the Event doesn't know that blockDrop or blockName is set

[quaint mantle]

Hello everyone, does someone here have experience with BouncyCastle lib? More specifically with performing ECDH

[dusty herald]

who knows

[eternal oxide]

or the OPItem is not what you are expcting

[steep nova]

I believe OPItem works

[eternal oxide]

sysout on it to be certain

[dusty herald]

yeah it is a static method 👀

[steep nova]

Because the plugin works as intended if I change blockDrops to something explicit like Material.STONE

[steep nova]

k

[heavy mason]

Would using a Set<Material> then picking a random element make any signficant difference?

[steep nova]

Sorry, I'm not familiar with Sets atm

[eternal oxide]

If that works then yoru switch is failign to set/access the blockDrop variable

[heavy mason]

Its fine, just curious

[steep nova]

True, but blockName is getting initialized just fine

[heavy mason]

Send a paste link of your current code

[wet breach]

what do you need help with?

[steep nova]

Like everything?

I already pasted the relevant parts

[wet breach]

I mean nothing special in how BouncyCastle does it vs say another crypto lib except efficiency

[steep nova]

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

[eternal oxide]

an easy test, add a setter for teh blockDrop in the class

[steep nova]

Public key is being encoded into Base64 and then sent using Socket to client from server. Client should decode Base64 and use decoded bytes to get PublicKey object

btw, it's also possible to use `

3 times

test

As I can see, bytes are correct, so I don't really know what's wrong

@quaint mantle

[steep nova]

I'm gonna try this next

[heavy mason]

Did you add the check for a null block?

[eternal oxide]

Well from the code you have shown I see no reason for it to not work.

[steep nova]

no

[quaint mantle]

@heavy mason If you mean for the code, I will push server code to GitHub and will send link. For client, code is the same

[steep nova]

should I?

[heavy mason]

No, I'm saying use a paste link instead of pasting large amounts of text that flood chat

[wet breach]

@quaint mantle Is client and server both something you made?

[heavy mason]

You should

[quaint mantle]

@wet breach Yes and no, some parts are from github xdd
https://github.com/inao-cz/bufferBot/blob/bouncycastle/src/main/java/me/inao/discordbot/server/KeyExchange.java

[wet breach]

The only thing I could see that could possibly be throwing it off, is that sometimes you have to specify which spec you are using, which there is two names for it.
prime256v1 and secp256r1. The second one is the more accepted name for it, while some are just fine with the former.

[quaint mantle]

Exception is being generated on line 31, decodePoint(raw)

[steep nova]

maybe you should cook it

its raw

[quaint mantle]

yes yes, bake it for 3 hours

[wet breach]

public org.bouncycastle.jce.interfaces.ECPublicKey loadECPublicKeyBC(String encodedPublicKey) throws NoSuchProviderException, NoSuchAlgorithmException, InvalidKeySpecException, IOException {

im trying to make a while loop for the player y being 256, i havent done a while true before but this is what ive got and its not working while (player.getLocation().getY() >= "264" (true) {

[mystic lion]

Do I have to close preparedstatements/statements after using them?

well not "have to"

but should I

[wet breach]

@quaint mantle Did you check that the public key value you have obtained is actually correct?

that would be the only other thing I could see going wrong, is that you are generating a key, and then from said key extracting the wrong public key using incorrect values from the private key

[quaint mantle]

@wet breach what pastebin do you use

[wet breach]

?paste

[queen dragon]

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

[quaint mantle]

thanks

[wet breach]

the last 6 values of the generated key is what is used to derive the public key if that better helps you @quaint mantle not entirely sure how well versed you are in crypto lol

[viscid cave]

Any one has an example of plugin that uses a websocket?

[quaint mantle]

Well, for getting the key, I'm using https://github.com/inao-cz/bufferBot/blob/bouncycastle/src/main/java/me/inao/discordbot/server/Connection.java#L34

And since key should be generated correctly (hopefully, it's in init function of KeyExchange.java)

    }

that is my event

but

here is what happens:

https://snipboard.io/OB5Uyh.jpg

it sets the lore

but its not enchanted

[wet breach]

@quaint mantle so the line you linked is for getting the public key from a key. So now the question is, the key being provided, is it a valid ECDH key? And is said key actually being used to encrypt the session or is it just the public key?

Never mind, I finally found the solution

[lost matrix]

What are you trying to do?

[distant fern]

Join:

import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerJoinEvent;

public class Join implements Listener {

        NPc.addJoinPackets(event.getPlayer());

    }


}

[quaint mantle]

which plugin like yours or other?

[molten hearth]

Other

[dusty herald]

aaa why is your class name NPc?

it's messing with my head

[steep nova]

I accidentally made two objects

[dusty herald]

its gonna explode

[steep nova]

That's why it was null

[quaint mantle]

xD

[paper viper]

plase dont use Main :0

[crisp iron]

@7smile7 how does that help? It only returns the world

the file for the world

[quaint mantle]

try this
if (getServer().getPluginManager().getPlugin("PluginName") != null) { getServer().getPluginManager().disablePlugin(getServer().getPluginManager().getPlugin("PluginName")); }
@molten hearth

[lost matrix]

Btw. Never throw a NullPointer yourself

[dusty herald]

is there an event for when a chunk is being generated for the first time never really put much mind to it

I know there's ChunkLoadEvent

[distant fern]

Anything else that might be wrong?

[dusty herald]

would that be called whenever a player loads a chunk?

[young knoll]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/world/ChunkLoadEvent.html#isNewChunk()

[dusty herald]

thanks bb

[lost matrix]

Yes. ChunkLoadEvent#isNewChunk()

[quaint mantle]

// Using an API
if (obj == null) return null;

// This IS an API
if (obj == null) throw new NPE

[dusty herald]

wow, such wisdom

[lost matrix]

What exactly does not work in your code? Do you always get your random NullPointer?

[crisp iron]

no, it just never loads the world

i wasn't receiving the null pointer at all

when i run /worldmng load test it says it loaded, but it never actually does

[lost matrix]

Throw some sysouts in there and see what lines get actually called.

[sharp mason]

Hi, I wish my plugin could search for players by coordinates, e.g. / examplecommand @a [x = 10, y = 20, z = 20], does anyone have any idea how to do this?

[molten hearth]

Well I don't want to disable it i want to cancel it ever calling onEnable

[paper viper]

use @urban grotto instead lol

wait what the fuck

change your name

lmao

[quaint mantle]

of course

but still, newbie programmers

[heavy mason]

Ironic

[rapid vigil]

Guys I need help with my code:

Location spawn = new Location(Bukkit.getWorld("ffa"), -1074, 80, 96, 175.5, -2.9); Why does it give me error on paw and pitch?

[quaint mantle]

g

[paper viper]

or you can use @Contract

[quaint mantle]

no

[paper viper]

@Contract also works

[lost matrix]

Yes. But most approaches are pretty slow. Why do you want to do that?

[paper viper]

you can also define purity with that as well

[quaint mantle]

an error message would be nice

[heavy mason]

Would be hilarious if that pinged someone

[rapid vigil]

I can't send here

[paper viper]

ikr lol

[rapid vigil]

I guess

[quaint mantle]

?paste

[queen dragon]

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

[quaint mantle]

send the error

[rapid vigil]

!paste

[molten hearth]

I might be able to use loadBefore and have the same plugin name so that it errors due to a duplicate name entry but I'd rather do it programmatically

[rapid vigil]

How do I upload a picture

[molten hearth]

Wait how am I gonna loadbefore the same plugin name pain

[sharp mason]

I'm creating a plugin that will work based on a Yes or No game and I need to detect a player from the given coordinates and would like to use @a, @r, @p etc.

[heavy mason]

Change the plugin name

[rapid vigil]

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

[heavy mason]

Ez

[rapid vigil]

This is the error: https://paste.md-5.net/equdoxakeb.bash

[fathom timber]

bro

[quaint mantle]

@rapid vigil you have to change x y z to double and yaw and pitch to float

[fathom timber]

^

[molten hearth]

But then it won't error due to a duplicate plugin name

Or can i dynamically change the plugin name

[heavy mason]

Arent you trying to avoid the error?

[heavy mason]

I dont think thats possible

[molten hearth]

No I'm trying to cause the error so that the 2nd plugin doesn't enable

[quaint mantle]

then do what i told u to do

[molten hearth]

You told me to disable it

[quaint mantle]

or just remove the plugin

[heavy mason]

Yes

That works too

[quaint mantle]

xd

[molten hearth]

I can't that's the problem lul

[quaint mantle]

then do what i told u to

[rapid vigil]

Location spawn = new Location(Bukkit.getWorld("ffa"), (double) -1074, (double) 80, (double) 96, (float) 175.5, (float) -2.9);

Like that?

[quaint mantle]

when its disabled it wont do anything

yes @rapid vigil

[molten hearth]

But it messes stuff up within it's onEnable

[lost matrix]

  public Optional<Player> getPlayerNear(final Location location, final double range) {
    return location.getWorld().getNearbyEntities(location, range, range, range, entity -> entity instanceof Player)
        .stream()
        .sorted((ent1, ent2) -> (int) (ent1.getLocation().distanceSquared(location) - ent2.getLocation().distanceSquared(location)))
        .map(Player.class::cast)
        .findAny();
  }

Get all players near a location
Sort them by distance from that location
Get nearest player if present

[rapid vigil]

That actually works, No errors but there's 3 warnings

[quaint mantle]

what warnings

[rapid vigil]

Casting '-1074' to 'double' is redundant
Casting '-80' to 'double' is redundant
Casting '-96' to 'double' is redundant

[sharp mason]

Thank you ❤️

[quaint mantle]

try just changing all the double to int

and leave the float as is ig

[rapid vigil]

Changed, but still same warnings

now it says:
Casting '-1074' to 'int' is redundant
Casting '-80' to 'int' is redundant
Casting '-96' to 'int' is redundant

[quaint mantle]

show the code like the method

[crisp iron]

i got it to work @7smile7 thanks

[young knoll]

IF you want them as doubles just append a d

[quaint mantle]

oh maybe try ((int) the number)

[young knoll]

For floats, f

[rapid vigil]

    public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
        if (sender instanceof Player) {
            Player p = (Player) sender;
            Location spawn = new Location(Bukkit.getWorld("world"), (int) -1074, (int) 80, (int) 96, (float) 175.5, (float) -2.9);
            if(label.equalsIgnoreCase("spawn"))
            p.teleport(spawn);
            p.setHealth(20);
            p.setFoodLevel(20);
            p.getInventory().clear();
            p.removePotionEffect(PotionEffectType.STRENGTH);
        }
    return false;}
}```

[fathom timber]

Does an or ```
|| work in a catch statement? like catch(IOExeception e || MalformedUrlException mue)

Would that be possible to attempt something like that?

[young knoll]

    @Override
    public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
        if (sender instanceof Player) {
            Player p = (Player) sender;
            Location spawn = new Location(Bukkit.getWorld("world"), -1074d, 80d, 96d, 175.5f, -2.9f);
            if(label.equalsIgnoreCase("spawn"))
            p.teleport(spawn);
            p.setHealth(20);
            p.setFoodLevel(20);
            p.getInventory().clear();
            p.removePotionEffect(PotionEffectType.STRENGTH);

Also don't catch generic exception

You shouldn't throw it either

[eternal oxide]

Be specific when adding them

[fathom timber]

aight

I was doing a discord webhook

[quaint mantle]

okay

[paper viper]

isn't it just 1 pipe

instead of two

[fathom timber]

no an or statement is 2

[paper viper]

but exceptions

you can chain them using |

[fathom timber]

u think?

[paper viper]

?

[fathom timber]

operator*

[quaint mantle]

yeah i think it is too only 2 exceptions

[fathom timber]

ye it is

i just checked on stackoverflow

[paper viper]

http://tutorials.jenkov.com/java-exception-handling/catching-multiple-exceptions.html#:~:text=In Java 7 it was,also known as multi catch.&text=As you can see%2C the,individual catch blocks for them.

[fathom timber]

How do I disable this?

https://gyazo.com/cfffc9bea14e3186b64c7811d25363f1

The Y/N prompt

[abstract relic]

u dont

just press ctrl + c twice

[fathom timber]

It wasn't like that before smh

[abstract relic]

how are you launching your server?

[fathom timber]

run.bat

[abstract relic]

start script?

[fathom timber]

Ye

[abstract relic]

i mean

u could just run a jar manually

[fathom timber]

true

I just prefer to do --nogui

[abstract relic]

no i mean

[quaint mantle]

yeah

[abstract relic]

java -jar <options> spigot.jar

[quaint mantle]

but like running a jar doesnt give u an console

[abstract relic]

it does?

[quaint mantle]

never did to me

[paper viper]

it gives you the console if you run it in command prompt. However, --nogui will not let the gui thing pop up

[fathom timber]

https://gyazo.com/688a1b5284e76fec4cca8001f0df1474

^

[quaint mantle]

yeah

[abstract relic]

well yea

[quaint mantle]

@wet breach I've solved it 😄 Problem was at sending whole key when I actually don't need it 😄

just runned the an 1.8.8 spigot jar didnt open anything

[abstract relic]

yea

[fathom timber]

i thought 1.8 was extremely buggy

[abstract relic]

they added console later

[fathom timber]

Ah

[abstract relic]

like i mean

the actual gui

[lost matrix]

Only if you start it from withing a terminal. stdout does not have to be piped into your terminal.
On linux you can just do java -jar <options> spigot.jar >> some.txt and pipe the console directly into a File.

[abstract relic]

i mean

thats what I meant the whole time

like manually launching the jar

is through terminal imo

ive always done it like that I guess but new spigot is cooler I guess

[sage swift]

but 1.8 is best!

wtfff

[abstract relic]

you are smoking crack

[quaint mantle]

yea

mana.containsKey(player)

[paper viper]

Couple things. The <String,Integer> part at the end isn't necessary and you should be using Map<String, Integer> mana = new HashMap<>(); instead because it allows your code to be more flexible

[quaint mantle]

yes it does

[sage swift]

storing players as strings very good

[wet breach]

@quaint mantle see I knew it had to be something with the key lol

glad you resolved it though

[paper viper]

and store players using UUID

not String

[quaint mantle]

@wet breach I had to do this: ((ECPublicKey)session.getKeyExchange().getPair().getPublic()).getQ().getEncoded(true));
Instead of: (session.getKeyExchange().getPair().getPublic().getEncoded());

😄

Ah that makes sense

[paper viper]

just do Map#get()?

[abstract relic]

it's better practice to define a map like this: ```java
public Map<String, Integer> mana = new HashMap<>();

[paper viper]

and check the value

[abstract relic]

Ideally you wouldnt even make it public

[paper viper]

i said that above 🥲

[abstract relic]

OH

IM SORRY

[paper viper]

nah all g

no

mana.get(player.getUniqueId()); to get the value right

then compare than to 100

[wet breach]

You only really need to do it that way if you expect others to be using your code. IE making an API. In which case you let the user decide what they want instead of forcing them to use a certain collection. Otherwise just stating it as a hashmap instead of a map is perfectly fine and acceptable.

🧐

no it wouldn't

that doesn't make sense lol

[abstract relic]

you're trying to use a uuid object as key in a map that requires a string

[sage swift]

then do Bukkit.shutdown()

[abstract relic]

ooh ok

i mean that could work yea

i'd probably go with mana.getDefault(player.getUUID(), 0) + 5 as value
