[quaint mantle]

let's see

Also another thing to look into is try-with-resource

You can do try (PreparedStatement statement = connection.prepareStatement()) {
…
}

It will automatically close your statement

closing the statement didn't really solve my issue

Well it was needed anyways :p as for your issue. Not really sure why it’s lagging the main thread when it’s being called asynchronously thTs weird

[lost matrix]

Accessing a database or any other IO on the main thread naturally produces lag

[quaint mantle]

Yea that’s the thing tho he’s doing it asynchronously by the looks of it, unless I missed something. I’m reading his code on my phone so maybe I read it wrong but looks good to me

maybe it's happening in other places?

how can I pinpoint it

[lost matrix]

I just read the question at the beginning XD
If you want to load player specific data then your should use the AsyncPlayerPreLoginEvent. There you can just access your DB as long as you want.

[quaint mantle]

does it not let the player join until the task has finished?

Do you make other DB calls or mess around with any files anywhere?

Events don’t complete until what you’re doing inside of the listener is finished

I do, hence why I needed help pinpointing the location

is there a way to do so?

Yea you can’t really pinpoint it you just gotta look at all your db calls and file usage

And see if you’re doing anything on the main thread

I think I'm (theoretically) doing it in async in every call

If I am inside a callback, am I working in the main thread?

i.e here

        Database.someStuff(result -> {
            Database.doSomeStuff();
        });
``` where someStuff is wrapped in a .runAsync task

Yea if you’re inside the callback as long as you run the call as a sync task it will be on the main thread

so in other words doSomeStuff is on the main thread?

maybe that's why it was lagging

Yes that’s correct

in what way can I edit Map asynchronously?

via a mutex?

How about a ConcurrentHashMap?

[wide flicker]

Anyone know how to prevent an arrow from being sent to clients when fired? (to make it completely invisible)

Tried sending an entity destroy packet immediately after firing the arrow, but it still sometimes appears for a frame or so

[quaint mantle]

Maybe listen to spawn entity packets and cancel it if it’s the right one

[rugged topaz]

can't use player#launchProjectile to launch a bat in the player's front facing direction, what's a solution?

or more particularly, i want to launch a bat from the player's face always following the direction of their crosshair

[wide flicker]

Try this. Adjust the value in .multiply() to whatever you want their velocity to be.

    Location loc = player.getEyeLocation();
    Entity bat = loc.getWorld().spawnEntity(loc, EntityType.BAT);
    bat.setVelocity(loc.getDirection().multiply(10));

[tardy delta]

in this case, does it creates a new instances on every loop?

[unkempt peak]

Yeah, just create the itemstack before the loop

Also you could just set every slot to glass pane and then set your other items overwriting the glass

[tardy delta]

true but then i would have to fill air blocks back in

[paper viper]

dude just please store that in a variable regardless if its in a loop or not

thats not readable lmao

[tardy delta]

uhh i only need it once

[paper viper]

It doesnt matter

its a large ass array

[tardy delta]

variables that i dont need..

[swift spear]

Trying to update my old plugin to 1.17 coming up with those 2 issues. 1. RandomPositionGenerator isnt a thing anymore? 2. The operator < is undefined for the argument type(s) boolean, double any ideas? 1.16 worked fine

[paper viper]

Its for readability, and you really should do it

[tardy delta]

hmwoa ok

[paper viper]

if people were to look at your code, they would be disgusted from how tight it is

store it outside

[vague oracle]

Surely creating 1 array over idk 50 times is better

[tardy delta]

but whats better now when i have only one class instance? making a field static or not when it doesnt really belong to an instance?

you mean to the chat?

(only he's able to see it)

a title on the screen?

liek this?

player.sendTitle()

if you added the spigot api as an dependency

[quaint mantle]

sorted :D

[tardy delta]

is that lang given a value every time an enum value gets loaded?

[round gale]

Is there some way to execute my /version command before the paper one?
(I know about the loadbefore, but I can't load before paper lol)

[tardy delta]

plugin commands should override the vanilla ones by default

[ancient plank]

/pluginnamespace:command

like /essentials:kill for example

[golden turret]

you could use something i call shape system

String shape = "#########" +
               "#xxxxxxx#"
               "#########";

char[] chars = shape.toCharArray();

int currentItem = 0;
for (char c : chars) {
  if (c == '#')
    //put glass
  if (c == 'x') {
    //put the item based on the currentIndex
    currentIndex++;
  }
}```

[rugged topaz]

if i wanted to manipulate the speed of a bat, would that be with nms or possible thru the API?

[ancient whale]

Hi, Does anyone know how to get the event trigger from Player#damage ? feels like entitydamage doesn't trigger from what I tested

[opal juniper]

it should

[ancient whale]

Well it actually does trigger when I use the damage(double,entity) but not when I use damage(double)

And I am using a plugin which seems to be using the damage(double)

Which doesn't trigger properly my events

[hardy agate]

is there a built in method for getting players nbt? (preferably as a raw string or dictionary)

[ivory sleet]

Player extends PersistentDataHolder

And PDC API is a way to talk with nbt

[hardy agate]

what does that return?

[ivory sleet]

PersistentDataHolder has the method getPersistentDataContainer which returns a PersistentDataContainer instance

?jd-s

[undone axle]

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

[ivory sleet]

search for persistentdatacontainer

should give you the methods you need

[hardy agate]

hm

this is more or less giberish

[eternal oxide]

?pdc

[undone axle]

https://www.spigotmc.org/threads/a-guide-to-1-14-persistentdataholder-api.371200/

[hardy agate]

and will this give me raw nbt?

I'm not trying to edit a players nbt

I'm trying to save it as a string

[eternal oxide]

explain your goal

[hardy agate]

variables

in mcfunction

${variable name}

the idea being that I could say something along the lines of
/var <variable name> = <selector>.getNBT(<path>)

[eternal oxide]

ok, the PDC is persistent. You save your data to the PDC and its on the player object until you remove it or the player data gets wiped.

[ivory sleet]

We still assume you’re coding this in Java

[hardy agate]

yes

but it's essentially going to find and replace, and send the edited command

[eternal oxide]

then yes teh PDC is what you want to use

[hardy agate]

and I assume there's something in the docs about this?

[eternal oxide]

we just linked you to teh docs and a tutorial

[hardy agate]

this link is different tho right?

[eternal oxide]

try reading it?

[hardy agate]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/persistence/PersistentDataContainer.html

also: the game stops while spigot is running something right?

like while I'm running the code of my parser, the server will freeze

[eternal oxide]

if you run it on the main thread, yes

protocolib's tab completer events... i see no javadocs... how can i modify that list sent to client?

[vast shale]

Im having issues with opening a custom inventory. I printed out the player's current open inventory and it appears to be changing, but no GUI appears..

Before openInventory(): org.bukkit.craftbukkit.v1_17_R1.inventory.CraftInventoryView@3a2ab454
After : org.bukkit.craftbukkit.v1_17_R1.inventory.CraftContainer$1@686a2933

Heres my methods. The message "Opening Win Inventory!" does appear.

    public void WinBattleGUI() {
        WinInv = Bukkit.createInventory(null, 54, ChatColor.GOLD + "" + "Exp");
        initWinInvItems();
    }
    
    public void initWinInvItems() {
        WinInv.setItem(0, createGuiItem(Material.PURPLE_CONCRETE, ChatColor.DARK_PURPLE + "" + "Test"));
    }
    
    public void openWinInventory(final HumanEntity e) {
        WinBattleGUI();
        e.sendMessage("Opening Win Inventory!");
        Bukkit.getServer().broadcastMessage("1: " + e.getOpenInventory().toString());
        e.openInventory(WinInv);
        Bukkit.getServer().broadcastMessage("2: " + e.getOpenInventory().toString());
    }

[eternal oxide]

At what point are you trying to open this inventory? in an event?

[vast shale]

After a battle finishes. I have a method "finishBattle" that invokes openWinInventory(player)

[eternal oxide]

are these triggered through an event?

[vast shale]

Yes, the battle starts on an NPCInteract event

[eternal oxide]

Your debug says you already had a view open when you opened your Inventory

[vast shale]

I run player.closeInventory and print it out. The same

org.bukkit.craftbukkit.v1_17_R1.inventory.CraftInventoryView@3a2ab454
``` is printed

Is there another way to force close and possible guis?

[eternal oxide]

are you doing any of this from an InventoryClickEvent?

[vast shale]

Yes

[eternal oxide]

finally

You need to read teh Javadoc on InventoryClickEvent

Hmm okay. I'll take a look. Am I missing something specific?

yes, very

read its comments

[vestal moat]

https://paste.md-5.net/kifimimufe.rb i just did ```java

String[] completions = container.getStringArrays().read(0);

[tame elbow]

PigZombie.setAngry() has 2 inputs a boolean and arg0. what would go in the arg0 space if the boolean is true?

[ivory sleet]

?jd-s check the docs

[undone axle]

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

[vast shale]

I've glanced through, specifically at InventoryClickEvent and am not seeing something obvious...

[tame elbow]

I was looking here, is this the wrong spot? https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/PigZombie.html#setAngry(boolean)

[eternal oxide]

Because InventoryClickEvent occurs within a modification of the Inventory, not all Inventory related methods are safe to use.

The following should never be invoked by an EventHandler for InventoryClickEvent using the HumanEntity or InventoryView associated with this event:

    HumanEntity.closeInventory()
    HumanEntity.openInventory(Inventory)
    HumanEntity.openWorkbench(Location, boolean)
    HumanEntity.openEnchanting(Location, boolean)
    InventoryView.close() 

To invoke one of these methods, schedule a task using BukkitScheduler.runTask(Plugin, Runnable), which will run the task on the next tick. Also be aware that this is not an exhaustive list, and other methods could potentially create issues as well. ```

[ivory sleet]

Do you use paper or spigot?

[tame elbow]

paper, i think

[vast shale]

But im using the interface Player not HumanEntity, is this still an issue?

[ivory sleet]

Check their docs then

[eternal oxide]

yes

[tame elbow]

do you mean for server software?

[vast shale]

What other object could I use? If I can't use Player or HumanEntity

[eternal oxide]

Player is a sub interface of HumanEntity

[vestal moat]

why r u ignoring me

[eternal oxide]

You do as teh javadoc says and use a runnable

read teh javadoc, it tells you to use teh scheduler to run a task 1 tick later

[tame elbow]

i think im using the spigot api, but paper server software

[eternal oxide]

?scheduling

[undone axle]

https://www.spigotmc.org/wiki/scheduler-programming/

[vast shale]

Hmm okay. So I should make a runnable that is invoked to close the player's inventory after 1 tick?

[eternal oxide]

no, to open your new one

[vast shale]

Hmm. I have a battle GUI that opens fine first, but then opening the WinInventory doesn't work. Why would it work on its first interion?

[eternal oxide]

because you are not opening yoru battle inventory through the InventoryClickEvent

[vast shale]

I'm not directly using the InventoryClickEvent to open the inventory. Will the runnable still fix my issue?

[eternal oxide]

You are calling the open method from the InventoryClickEvent

[vast shale]

Not directly, but eventually

[eternal oxide]

it all branches FROM the event. Its an event based system

you are still IN the code path of the event when you call open

[golden turret]

?paste

Ahh gotcha, thank you for sticking with me!

Look right?

Could anyone help me in my thread? About setting zombified piglin agro.

[golden turret]

hello. im trying to do a simple registry system for an ArgsReader, but when i try to add a new reader to it intellij warns me about deadlock (see print). i dont like to see warnings so i would like to remove that
ArgsReader: https://paste.md-5.net/xexacoqiru.java
ArgsReaderRegistry: https://paste.md-5.net/retodakehi.java
StringReader: https://paste.md-5.net/qehayoruci.java

[eternal oxide]

Yeah thats probably not going to work

You are trying to create an instance of StringReader, which is a sub class of the class you are in., which has not yet finished being intitialized

your abstract class does not actually exist yet when you try to sub class it in StringReader

[golden turret]

hm

alright

what do you recommend

[eternal oxide]

separate it from your registry

[ivory sleet]

Also y static 😐

[eternal oxide]

Your registry should be autonomous and not depend upon anything

[tame elbow]

Zombiefied Piglin automatically attack players off spawn

[mint flare]

Hey !

I actually create an inventory like a backpack of 27 slots and i put 9 differents item in the first line, 9 red stained glass in the second, and the third is empty.

What event i have to use to see when a player put one item in one slot of this backpack ?

thanks in advance

[golden turret]

inventoru click

[mint flare]

this works if one player just shift+click on item ? 🤔

[golden turret]

yes but it will be called on the player inventory

[mint flare]

Arf :/

[golden turret]

so you need to check the top inventpry

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/inventory/InventoryDragEvent.html

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/inventory/InventoryClickEvent.html

the first is the normal click

you click and then click in the target inventory with the item in the cursor

so you just need to check the clicked inventory

the 2nd you need to see if it is a shift click

if so you need to verify if the top inventory is your backpack and if it is empty

[lost matrix]

You should not check every time a player adds something to his backpack. Just listen for the InventoryCloseEvent, then serialize the content.

[lost matrix]

Make your ArgsReaderRegistry a singleton which holds its own instance

[mint flare]

this does not seem to me very suitable for my functionality, since I will have to compare the item (put in 3rd line by the player) with the one on the first line to see if it is the right one and to grant the point

if so you need to verify if the top inventory is your backpack and if it is empt
it seems to be a good id i'll search this way, thanks

[round gale]

nope, unfortunately not working

[young knoll]

You can replace it using the PlayerCommandPreProcessEvent

[lost matrix]

Do you want to actually overwrite a fully namespaced command like
/minecraft:help
Otherwise just registering /help would override the default help command unless you used the full namespace

[young knoll]

Doesn't work with spigot commands, which may be the issue

Since spigot replaces /help afaik

I did this in the past

    @EventHandler
    public void onCommand(PlayerCommandPreprocessEvent event) {
        if (event.getMessage().equalsIgnoreCase("/plugins") || event.getMessage().equalsIgnoreCase("/pl")) {
            event.setMessage("/plugingui:plugins");
        }
    }

[round gale]

I'm using this code. so it should work, if paper cmds are replacable

public class VersionCommand implements CommandExecutor {
    @Override
    public boolean onCommand(@NotNull CommandSender sender, @NotNull Command command, @NotNull String label, @NotNull String[] args) {
        FileConfiguration config = CustomVersionSeedCommand.plugin.getConfig();
        if (sender.hasPermission("CustomVersionSeedCommand.original.versioncommand")) {
            Bukkit.dispatchCommand(sender, "bukkit:version");
        } else {
            Set<String> lines = config.getConfigurationSection(ConfigVariables.VERSION_SECTION).getKeys(false);
            for(String one_line : lines) {
                sender.sendMessage(one_line);
            }
        }
        return true;
    }
}

(I do not have OP Permissions)

[lost matrix]

Sysout which branch gets called

[round gale]

okeydokey

[round gale]

just /version

[lost matrix]

Also this can just be bypassed by a user if he just types /bukkit:version instead of /version

[round gale]

you can block that with permissions. What my "client" wanted, was a plugin that can output a funny message, when you type /version

[tacit mica]

There's no event for when tile entities are initialized, right?

[lost matrix]

Then just use the PlayerCommandPreprocessEvent

[round gale]

no branch's being called

[round gale]

okey, this isnt gamebreaking hopefully xd

[lost matrix]

Meh. Best you can do is this:

  private void initTileEntity(final BlockState entity) {
    // Init/Check your tiles here
  }

  private void initChunk(final Chunk chunk) {
    Arrays.stream(chunk.getTileEntities()).forEach(this::initTileEntity);
  }

  @EventHandler
  public void onWorldLoad(final WorldLoadEvent event) {
    Arrays.stream(event.getWorld().getLoadedChunks()).forEach(this::initChunk);
  }

  @EventHandler
  public void onChunkLoad(final ChunkLoadEvent event) {
    this.initChunk(event.getChunk());
  }

And dont forget to enable your plugin before the worlds load so that the default chunks in the default world are also affected.

[round gale]

okey thank you

[tacit mica]

Yeah that was what I had, quite messy

One thing though I just remembered

Actually nevermind

[round gale]

Still not working :/

public class VersionCommand implements Listener {

    public static final String BUKKIT_VERSION = "bukkit:version";

        String command = e.getMessage();
        Player player = e.getPlayer();

        player.sendMessage("I am being called!");
        player.sendMessage(command);

        if(command.equalsIgnoreCase("/version")) {
            if(player.hasPermission("CustomVersionSeedCommand.original.versioncommand")) {
                e.setMessage(BUKKIT_VERSION);
            } else {

[rotund patio]

So I have the standard plugin channel setup, where

player.sendPluginMessage(Plugin.getInstance(), Constants.API_CHANNEL_ID, out.toByteArray());

However, my forge client doesn't receive this. I'm sure that the forge client works for vanilla plugin channels (minecraft:register).

[ornate patio]

if I send chunks to a client outside of render distance using protocollib, will the client just throw it out or nah?

[fallow merlin]

the client wont care if its outside their own render distance right?

[arctic moth]

is there a way to change mob fire rate or does that require forge

[ornate patio]

im just trying to teleport someone millions of blocks away without having the couple seconds of unloaded chunks

[arctic moth]

like make things shoot really fast

[arctic moth]

theres probably a load chunks thing, just get the chunks at the tp coords and load them and then tp

[ornate patio]

yeahs that’s what I’m tryna ask, if pre-loading chunks would even work

[arctic moth]

idk

try

[ornate patio]

i have no idea how, and I’ll have to learn protocollib to try it

[dense geyser]

How do you get the offline UUID of a player?

[eternal night]

what is an offline uuid of a player o.O

[young knoll]

The UUID used in offline mode

It's somehow computed by their name

[dense geyser]

the UUID thats returned when you try to get that of a player in offlinemode

WAIT I worked it out

UUID.nameUUIDFromBytes(("OfflinePlayer:username").getBytes()) interestingly simple

[rancid pine]

for the attributemodifier, on the operation you can add numbers, but there is no method to set the attribute equal to a certain number

all you can do is add and subtract

does anyone have any ideas?

[brave trellis]

how would i use '' inside a yml configuration and get it as a string, for example

thing:
  - 'd''

and get it as d'

[sullen marlin]

"d'"

[brave trellis]

thank u

[sullen marlin]

Attribute base value? No modifiers needed

[rancid pine]

thanks bro

[brave trellis]

what if its something like d" ' d ' " to get the string

is it the same?

[sullen marlin]

Idk !!str or a text block maybe

Go check a yaml guide

Or just call .set in your code and see what spigot does

[brave trellis]

Hey ! Someone know how to know if the cursor have no Item (in inventory) with getCursor ?

[jade perch]

I assume the value of get cursor would be null

[mint flare]

Me too but getCursor().toString() return : ItemStack{AIR x 0}

[jade perch]

Then check if it's equal to air

[mint flare]

it not match with ItemStack(Material.AIR,0) or ItemStack(Material.AIR)

[jade perch]

Itemstack.getmaterial == Material.AIR

[quaint mantle]

getType

[jade perch]

Yea that

[quaint mantle]

if you didnt switch to web dev you would've known that

[jade perch]

Intellij remembers for me

[mint flare]

Owh good idea x)

Yes ! It works ! Thanks a lot 🙂

[jade perch]

Np

[mint flare]

And in 1.8.9 can we differentiate 2 wools ? (different colors)

[jade perch]

Easiest way would probably be XMaterial

[young knoll]

Or the legacy MaterialData

[mint flare]

it's not Deprecated ?

[jade perch]

I mean it's 1.8 so

[mint flare]

true

all in .getData() is Deprecated even in 1.8 =' (

[jade perch]

Just use XMaterial

[mint flare]

I don't know what it is, I'll get some information! Thanks

[young knoll]

I mean there is nothing stopping you using it

Don't think MD is going to go back to 1.8 to remove it

I'm trying to order and group player attacks based on a saved integer within objects attached via their UUID.

Does anyone have a clever way of doing this?

[quaint mantle]

Hey, I read you can't track when a player opens their own inventory (since it's client-sided.) what's the next best thing/event?

Wait for them to click something I guess

just InventoryClickEvent? do I need to do something to determine it's the players inventory and not another?

check out the forum link above^

and be ready to spend a pretty penny for a dev

[humble garnet]

Any roughy idea of a cost ?

[drowsy helm]

depends on the dev, some do per project, some per hour

starting from 15/hr for a decent dev

thats a rough estimate, idk some devs charge different

[humble garnet]

Ah ok I see

Sorry to sound like an idiot, but how do I write a post in the forum? ( I have an account)

[drowsy helm]

on the top right theres a blue "Post New Thread" button

[humble garnet]

I need atleast 20 posts and a week old account

[drowsy helm]

oh yeah for resources you need some posts

[rotund patio]

bump

[eternal oxide]

Have you ever programmed before?

[eternal oxide]

Have you ever programmed before?

[humble garnet]

No, I have no experience

I have coded on FIVEM

But never in Java

[drowsy helm]

what lang does FIVEM support

[young knoll]

The heck is fivem

[quaint mantle]

I think it's lua

[young knoll]

Oh no

[drowsy helm]

gta roleplay thingo

[young knoll]

[drowsy helm]

pog

[quaint mantle]

"FiveM supports the general purpose programming language Lua as one of its scripting languages. Lua is a very easy language to learn, simple to use and fast to write. To use Lua, just use . lua in your scripts file extensions."

[drowsy helm]

i learnt lua maybe 5 years ago

i hate it

[young knoll]

Skript but LUA

[fallow merlin]

Lua is a very easy language to learn if u hate urself

[young knoll]

Actually that could be kind of neat

[fallow merlin]

or play roblox

[drowsy helm]

i mean theres a lot of lua interpreters out there

[eternal oxide]

I'd suggest before you start trying to setup a server (if you want to learn), first learn the basics of java and write some hello world apps.

[drowsy helm]

a lua version of skript wouldn't be out of the picture

[young knoll]

Would be less cursed

[quaint mantle]

would take a long time to make an op prison server core because of the optimizations needed but I believe you could do it 😄

@humble garnet

[eternal oxide]

Theres a few people about who would teach, but not the real basics. You must at least know how to use an IDE and write a java program

[young knoll]

Is optimization that important for op prison

[humble garnet]

Ok thank you, I’ll have a look around, it would probably be a lot quicker and better done if I find a dev though, but I will make sure to have some skills prior! Thank you all for the help

[ancient plank]

fivem supports c# too iirc

I used to make fivem c# server addons

[humble garnet]

Ok cool! If anyone knows of any developers looking for work, please let me know! I’m trying to get this sorted as soon as possible!

[vocal cloud]

What kind of work

Prison work. Depends on what you need lol. It can cost a few bucks to hundreds depending on many factors

hey if I want to learn how to make custom plugins is visual studios a good software to do so? Im asking this as im already familiar with visual studios as I use it for python projects

[ivory sleet]

I’d suggest an actual ide

[chrome beacon]

It is one

[ivory sleet]

But you can make visual studio code to work like an ide with extensions

[chrome beacon]

He said visual studio not vs code

[ivory sleet]

Oh nvm

[chrome beacon]

Too be fair he might be talking about vs code

[ivory sleet]

Ye lol

[sharp saffron]

its da same thing

[chrome beacon]

It's really not

[sharp saffron]

well im an idiot xD

[chrome beacon]

VS code is a fancy text editor. VS is a full IDE

[sharp saffron]

oh

My plan is to make a custom crates plugin

but im gonna start with something more simple as im not that dumb

[chrome beacon]

I recommend using Intellij for plugins. And then you can use Pycharm for Python

[sharp saffron]

ill check them out

[ivory sleet]

Are you quite the new one to Java or just the spigot api?

[sharp saffron]

im a beginer so I know how to do website (html css) and ik the basics aswell hex and binary good enough to know what im doing but im relatively knew to Java and spigot api

[ivory sleet]

Ah okay yeah then initiate with something simpler

[sharp saffron]

im gonna just start with a simple ping pong command

[ivory sleet]

Sounds good

[chrome beacon]

I'd read through one of the Java tutorials too

[sharp saffron]

in terms of difficulty is do you guys know if java is harder or easier than python?

[chrome beacon]

Harder

[sharp saffron]

k

[chrome beacon]

Python is a quite easy language to learn

[sharp saffron]

yea

[chrome beacon]

Which is why many recommend it for beginners

[ivory sleet]

Igloo did you work with object orientation regarding python?

[sharp saffron]

nah i recommend scratch lmao

[sharp saffron]

more or less

well anyway ima get started thanks for the help

[chrome beacon]

True but when you want to start with a real language

[sharp saffron]

ya ik i was joking

last question is intellij free?

[chrome beacon]

Yes if you use the community edition

Same goes for pycharm

[sharp saffron]

right one?

[ornate spire]

yes

[summer scroll]

How can I achieve items rotation like this?
https://i.gyazo.com/2ca109065346384a25ea85dc435b37c7.gif

[tacit drift]

a rotating armorstand

[summer scroll]

Yeah but I don't know the math for the rotation

[tacit drift]

make a task with a infinite loop that changes setHeadPose constantly

i think

[ivory sleet]

Probably want to set the right arm to reach right out such that you get a right angle between the arm and the body, then manipulate the body pose

[summer scroll]

Done the arm

[ivory sleet]

You’ll have to use an EulerAngle for setting the body pose

[sharp saffron]

quick question so ive just downloaded intellij and minecarft developer but for the project SDK what do i select?

[tacit drift]

install a JDK

https://www.oracle.com/java/technologies/downloads/ https://openjdk.java.net/install/

[summer scroll]

What should I use to rotate the body?

to rotate it in a task

[tacit drift]

i think intellij can install a jdk by it self too idk

[onyx fjord]

@summer scroll i had a fucking weird dream...

[sharp saffron]

it tells me i can install version from 1.8 to 17 is there any in particular or does it not matter?

[summer scroll]

wut

[onyx fjord]

So I had a dream

About your backpack plugin becoming free

Yeah...

[summer scroll]

hahahah

[onyx fjord]

I swear to god

I thought it's real

That's how you end up

Being on spigot 24/7

[summer scroll]

you like it huh?

[tacit drift]

Too much minecraft in your life

😳

[sharp saffron]

im pretty sure that called insanity

[summer scroll]

um the ArmorStand#setRightArmPose doesn't seem to be working for me for some reason.

Still downwards like this

[acoustic widget]

Hello, do you guys use library or something else for easy database managment ? I would like to provide for my future plugin every type of database like h2, json, mysql, sqlite

[tacit drift]

Look at what LuckPerms does

https://github.com/LuckPerms/LuckPerms/tree/master/common/src/main/java/me/lucko/luckperms/common/storage

[quaint mantle]

guys

i wonder what if i remove the unsafe values in spigot?

[quaint mantle]

@hazy rose https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/EntityType.html#EXPERIENCE_ORB

Use World.spawnEntity() and pass this value as the entitytype

[valid solstice]

if(!(player.getInventory().getItemInMainHand().equals(BaowgsPick.baowg_pick))){
            player.getInventory().addItem(player.getInventory().getItemInMainHand());
            return;
        }

why is this if statement triggering but when it adds an item to my inventory, it is EQUALS to the item im holding

[little trail]

what database should i use

not too much data

like probably a row per player

[drowsy helm]

i dont understand the phrasing? You are adding the item in their hand if it matches

[hazy rose]

int expAmount = 100; ExperienceOrb orb = null; Location loc = /*someLocation*/; ((ExperienceOrb) loc.getWorld().spawn(loc, ExperienceOrb.class)).setExperience(expAmount);

[valid solstice]

its for debugging purposes...

[drowsy helm]

depends on your needs, sql or mongo should do the trick

[little trail]

yes, which sql db

i know how to do it in python but not java

[hazy rose]

How i can make it repeat

[drowsy helm]

mysql is easy to setup and use

[little trail]

alr ty

[drowsy helm]

make what repeat?

[little trail]

does postgres exist for java too?

[valid solstice]

i am adding the item in their hand IF their item is NOT equal to a certain itemstack, but the item given to me when i tried it is equal to that certain itemstack

[drowsy helm]

yeah it does

[valid solstice]

for/while loop

[drowsy helm]

postgres is just a database, its the library you are looking for

[hazy rose]

Exp bottle drown

[drowsy helm]

just use a for loop

[little trail]

would this be good? https://github.com/alaisi/postgres-async-driver

[drowsy helm]

is baowgs pick just a static itemstack?

[valid solstice]

yea it is

[drowsy helm]

just use jdbc

[drowsy helm]

if its a custom item you should make a handler class, you cant give the same itemstack to all players

[hazy rose]

Do u have plugin who make exp bottle drown from no where just by using command?

[ivory sleet]

Believe you could just use something like hikari

[valid solstice]

the "giving the itemstack to players" is a debugging line

my question is, why is the if statement getting satisfied?

when infact, it should not

[drowsy helm]

thats what im saying

[little trail]

a uh ping reply wouldve been cool so i wouldve seen it easier

[drowsy helm]

you are testing with the Baowgs pick in your hand right

but it is still being satisfied

[valid solstice]

yup

so how would i make it not satisfy

theoretically, it should not be satisfied

[drowsy helm]

dont use a static itemstack and make a proper handler

[valid solstice]

wdym by proper handler?

[drowsy helm]

like a wrapper class for custom items instead of a static variable

ill send through an example, give me a sec

[valid solstice]

mhm sure

[ivory sleet]

Uh I have it to toggled off by default and cba to turn it on😅

[drowsy helm]

https://gist.github.com/Lickymoo/708d81dd1da480718359bb859d97c6b4

something like that where you have a method to check whether an itemstack is actually a custom item

far better than using one static itemstack

think about it, if you give 10 players the same itemstack, it will share all the same data

[valid solstice]

why would i need to check whether an itemstack is actually a custom item

[drowsy helm]

stack size, enchant etc etc

so you can handle it properly

just checking whether item in hand = static itemstack is crude and won't work in many circumstances

[valid solstice]

so ill just create a getter that creates a new copy of the item stack and returns that item stack?

then in my listener ill run the getter method

thats what im understanding

[drowsy helm]

yeah, then to check whether it actually is a custom item have a method in the custom item class

[valid solstice]

alright ill try that out, thanks

[drowsy helm]

unless you want to check material, name and lore but that is a big workaround

and can be cheated easily

[valid solstice]

yea ill stick with itemstack

will if(!(player.getInventory().getItemInMainHand().equals(BaowgsPick.baowg_pick))){ get satisfied if the itemstack from getiteminmainhand has a different durability than the itemstack?

[drowsy helm]

well in an ideal setup you would just use

ItemStack hand = player.getInventory().getItemInMainHand();
if(itemManager.getHandler(hand) != CustomItem.BaowgsPick){
//do stuff
} ```

that getHandler method would return an enum

and the enum being a list of all your custom items

the struggle with comparing an itemstack to a static one is data will vary. durability, stack size, name etc

[summer scroll]

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

Will ignore the stack size.

Honestly you can just use PDC I guess, make things easier.

[drowsy helm]

yeah but theres many cases where custom items will vary with lore etc

^ my example uses nbt

[summer scroll]

Yeah true, nbt it is then.

[little trail]

so if im using postgres, do i just create the db with the postgres user with CREATE DATABASE then login to that db with the same postgres user?

i guess ill do that then

actually it wont even work for stuff like minehut as well i dont have access outside of the mc server and my folder so ig sqlite

[drowsy helm]

wdym stuff like minehut

[silver shuttle]

How do you register commands without reloading a plugin AND without adding the command to the plugin.yml?

for example, how do commandalias plugins do it

[drowsy helm]

checkout plugin.yml annotations

[eternal oxide]

a command alias plugin should not be registering any commands

its just providing aliases for existing ones

[silver shuttle]

okay but a plugin like ezcommands

makes own commands and registers them

how does one do that

[eternal oxide]

reflect into the command map

[silver shuttle]

aaah okayy

[eternal oxide]

https://github.com/TownyAdvanced/Towny/blob/3e87fa82b13a52b01e1afe2d2a6b10f42c557e67/src/com/palmergames/bukkit/towny/Towny.java#L1014

[silver shuttle]

thats cool

[summer scroll]

but you still need to register it in plugin.yml

[eternal oxide]

no you don't

[summer scroll]

really?

[eternal oxide]

not when reflecting

[silver shuttle]

would be useless if you did have to

is it even possible to change the plugin.yml by the plugin itself?

[eternal oxide]

no

[silver shuttle]

no right? since its compiled etc

[eternal oxide]

its not that its compiled, its that its in use

[silver shuttle]

ah ok

[silver shuttle]

why are methods like sendTitle deprecated and replaced over time?

[round gale]

I use it too in one of my Plugins, i don't know why they aren't deprecated in the SpigotMC API Website but in IntelliJ

[eternal oxide]

teh javadocs and Intelij are identical deprecations

sendTitle (if I remember) the two arg method was deprecated. You have to use the full 5 arg method

[round gale]

actually not. Like I looked twice or more, it had the same arguments, etc etc. but it was deprecated in IntelliJ but not on the docs

[eternal oxide]

just use -1 for all thre ints and it works identical to the deprecated method

[silver shuttle]

sendTitle can use 5 arguments

[round gale]

ye, in IntelliJ it is / was deprecated

[eternal oxide]

yes https://hub.spigotmc.org/javadocs/spigot/org/bukkit/entity/Player.html#sendTitle(java.lang.String,java.lang.String)

[silver shuttle]

showTitle uses 1 argument

[eternal oxide]

deprecated

inteliJ uses those exact same javadocs

[round gale]

this is deprecated in intellij.

[eternal oxide]

no

thats the 5 arg method

[round gale]

Ye, there you go

[tardy delta]

whats this?
java.lang.ExceptionInInitializerError: null

[silver shuttle]

that one is deprecated

[eternal oxide]

That is Paper not spigot

[silver shuttle]

oh kk

[round gale]

lol.

[eternal oxide]

well, theres a null in th error

[tardy delta]

ah i found it

[round gale]

wait how do you open this window?

hover over it long enough, okey okey

[silver shuttle]

very useful ^^

does anyone know how to remove the dependency of citizens for goldencrates I dont want to pay the 10$ and I generally dont need it as its described as an optional dependency here is the source codehttps://github.com/nulli0n/GoldenCrates

[summer scroll]

What happens when you run it without Citizens? It says that the Citizens is optional dependency, not required/mandatory.

[silver shuttle]

if its in the depend of the plugin.yml just remove it

[sharp saffron]

I get a few error messages

[silver shuttle]

its soft so you should be fine

I think the method this.getCitizens() on the GoldenCrates source code causes the error that you got. https://github.com/nulli0n/GoldenCrates/blob/master/GoldenCrates/src/su/nightexpress/goldencrates/GoldenCrates.java#L133

citizens is free

they have a jenkins

yeah

oh shoot its getLocation

nope i have no hope

[fallow merlin]

ook then

        }
        Location loc = Player.getLocation();
        TestNMS NMS1 = new MySuperZombie(((CraftWorld)world).getHandle());
        NMS1.setPositionRotation(loc.getX(), loc.getY(), loc.getZ(), loc.getYaw(), loc.getPitch());
        ((CraftWorld)loc.getWorld()).getHandle().addEntity(NMS1, CreatureSpawnEvent.SpawnReason.CUSTOM);

    }

Im trying to do the nms thing

oh god i forgot i need to put it inside commandexecutor

[little trail]

you know java // codeblocks exist so stop() { using = snippets; }.likeThat();

[tardy delta]

goldencrates hates me

[plucky crow]

This command can be executed only from the game!
Can I remove the error without changing the plugin?
There are some commands that don't need console and I want to run these commands through console.

which command?

[plucky crow]

digitalclock /dc runclock 1

http://dev.bukkit.org/bukkit-plugins/digitalclock/

probably not

never further

so no need to do > and <

[deep sail]

Does the file exist?

[acoustic pendant]

hmm

the error is this:

[glossy venture]

ur attempting to save your file before its loaded

or it doesnt exist at all

check if YamlConfiguration.loadConfiguration(file); returns null if it doesnt exist

[acoustic pendant]

when a player joins it creates a file

[deep sail]

Rather than file.getParentFile().mkdirs();

[deep sail]

Oh so it does exist already

Hm

[glossy venture]

nah that will create the file itself as a directory

[acoustic pendant]

wait

[acoustic pendant]

when i start the server, it returns this error

not when i join...

[acoustic pendant]

you mean something like this?

            if (!file.exists()) {
                customFile = YamlConfiguration.loadConfiguration(file);
            }

[summer scroll]

the file needs to be exist before you use it with loadConfiguration

[acoustic pendant]

so like that it should work ig?

i'm checking if the file exist

and if it does it creates

right?

@summer scroll?

[glossy venture]

other way around

[summer scroll]

you need to create the file first before using loadConfiguration

[glossy venture]

if (!file.exists()) {
  file.createNewFile();
}

customFile = YamlConfiguration.loadConfiguration(customFile);

[acoustic pendant]

i'm doing it already

[glossy venture]

or use

if (!file.exists()) {
  throw new IllegalArgumentException("file doesnt exist");
}

customFile = YamlConfiguration.loadConfiguration(customFile);

[glossy venture]

ur checking if the file doesnt exist

in the 2nd one

and also

u need to create the file itself

[acoustic pendant]

ye ye, that was now...

[glossy venture]

file.createNewFile();

[unique hamlet]

how do you enchant an item past its cap?

[summer scroll]

with spigot api or?

[acoustic pendant]

i have it already

[glossy venture]

ItemMeta#addUnsafeEnchantment();
``` i think

[unique hamlet]

lemme try that

[young knoll]

It’s just addEnchantment in the meta

[unique hamlet]

oh yteah that's literally a thing

nice

thanks :D

[glossy venture]

then you are trying to save the file before u have loaded it

as customFile is null

[acoustic pendant]

no?

save is after

[glossy venture]

you are creating an empty file

[acoustic pendant]

yes

[glossy venture]

i think it might return null

as it doesnt have anything to load

[acoustic pendant]

uh

[glossy venture]

but im not sure

(can anyone please help me, if this is optimized?)

[acoustic pendant]

hmm

[tardy delta]

wait what else return

[round gale]

isn't it so, when you make this, the event handler "aborts" so just ends his changes and things?

[tardy delta]

no

if no clause is found it just exits the method

[acoustic pendant]

i tried with dataStoreOnJoin.get().addDefault("hello", "yes");

java.lang.NullPointerException: Cannot invoke "org.bukkit.configuration.file.FileConfiguration.addDefault(String, Object)" because the return value of "me.fragment.minespaceskills.store.dataStoreOnJoin.get()" is null

this error

[round gale]

so i can just delete the else and return and it's fine?

[tardy delta]

yes

[plucky crow]

player.playSound(player.getLocation(), Sound.LAVA, 0.4f, 1.0f);
How do I get the sound to be heard everywhere, not just in one spot?

[eternal night]

You'll presumably want to sent the sound to every player ?

[plucky crow]

no just one player

[eternal night]

What do you mean with everywhere then ?

[plucky crow]

I changed the lava sound, it is a long sound but it is not heard from a certain block away.

[eternal night]

Concerning you are using the players location, it would always be heard

[plucky crow]

just my bad english

There is a sound of lava at the player's location, but when she moves away, the sound becomes muted and inaudible until she goes to the place where the sound started.

I just want to extend the reach of the sound.

i solved
just player.playSound(player.getLocation(), Sound.LAVA, 1000.0f, 1.0f);

[tardy delta]

how does inventory instanceof SomeClass works?

does the class needs to have an Inventory field?

like it worked before

[chrome beacon]

The inventory has to be an instance of SomeClass for that to work

[tardy delta]

cant i just check if inventory instanceof ParentClassOfCustomGui?

liek i have custom gui classes like TradeGui, ShopGui and in the inventory click event i'm checking if the inventories are instanceof GuiCreator (which is the parent class of all those mentioned before)

[humble garnet]

anyone know which plugin is used to make a pickaxe have custom enchants? play.wildprison.net ( the one use on there)

[tardy delta]

hello?

[acoustic widget]

What is the best way to use InventoryClickEvent ? I have created custom GUI menu and I have some codes on items in this custom menu but i would like to be sure I don't send my action to another gui menu ?
how do you guys do that ? I see many tutorial using itemname (if itemname = "blababla) do this, but I think it's a bad pratice because if two gui menu use same item name, my code will be run

[eternal oxide]

If all your classes extend/implement your parent and your parent is a sub of Inventory

[tardy delta]

but if that would be a subclass of inventory, i would have to define all those methods

idk why but instanceof worked everytime and now it doesnt

[eternal oxide]

it has to actually be an instanceof Inventory for it to be true

[tardy delta]

but how can i check then if the inventory is from one of my custom gui classes?

as instanceof doesnt work

[eternal oxide]

you compare the inventory instance,

[stone sinew]

InventoryHolder

[tardy delta]

to what?

[eternal oxide]

==

if (inventory == yourGUI.getInventory())

[tardy delta]

but the problem is that there are multiple instances

[eternal oxide]

and?

[tardy delta]

i cant check that for every instance

[eternal oxide]

why not?

[tardy delta]

because i'm not storing them somewhere and the amount of them could be big

[eternal oxide]

You have to be storing them at some point

[humble garnet]

anyone know where i can change the server listing name ?

its not in properties.yml

[stone sinew]

InventoryHolder Cough

[tardy delta]

hmm if i just let my super class implement inventoryholder, can i check then if the event.getInventory().getHolder() instanceof Superclass?

[stone sinew]

Not like I said it twice

[tardy delta]

there is no other easy way

[eternal oxide]

^ yes

[tardy delta]

lets try that

but its strange that this doesnt get logged

[eternal oxide]

GuiCreator is not an Inventory

it should trigger that

[tardy delta]

cringe

[eternal oxide]

I'd have to guess you forgot to register the listener?

[tardy delta]

no

[zinc spire]

Is there anyway to store Itemstack into mysql except serializing itemstack to base64?

[eternal oxide]

not simply, no

[zinc spire]

oh...

[tardy delta]

now this gets logged

[mint flare]

Hey, little fast question, when we spam click on an Inventory, InventoryClickEvent can't catch all click right ? 🤔

[humble garnet]

im using crateKey, and the createtier command isnt working ? any ideas ?

[eternal oxide]

you need #help-server

[humble garnet]

o thanks

[lean bone]

I am trying to load maps onto item frames on server start, but for some reason the item frame entities cannot be found. On server start there are 0 entities in the chunk where the item frame is supposed to be, but 30 seconds after server start there are, even though the chunk is loaded in both cases. Is there something I can do about this?

[crimson terrace]

you may be checking before the entities are loaded

[lean bone]

Is there any way to load the entities?

[tardy delta]

any explanation why it doesnt work?

[lean bone]

I tried using chunk#load() but that didn't seem to do anything

[stone sinew]

ChunkLoadEvent

Chunks aren't loaded instantly

[eternal night]

Eeeh, 1.17 separate chunk and entity loaded

loading*

[lean bone]

Is there any way to load the entities

[eternal night]

Use I believe it's EntitiesLoadEvent

It's called whenever the entities of a recently loaded chunk were finished loading

[lean bone]

I know, but my plugin uses POSTWORLD on load, and logging chunk#isLoaded was true

[eternal night]

Yeah, again a chunk being loaded does not guarantee its entities being loaded

[lean bone]

Yes I understand, I'll see if I can listen to the event

[mint flare]

It's weird, my InventoryClickEvent don't catch all click.. it's a problem of allowed RAM ? 🤔

[tardy delta]

which clicks doesnt it catch?

[mint flare]

about one left click out of 10

It isn't type click problem, just sometimes he ctach the click, and sometimes (more rarely) not

It's a problem cause at each click on a backpack inventory i have to compare the item with an other and if all click isn't catch i can't compare 😦

[acoustic widget]

@tardy delta i think this could be usefull https://www.spigotmc.org/threads/how-to-check-if-a-player-clicked-a-custom-inventory.486230/ (by comparing holder)

[tardy delta]

smh i forgot the this

now it seems to work

[rugged topaz]

hey, considering this returns a map ProxyServer.getInstance().getServers() am i suppose to grab the value of each element in the map or is there another way to get all the servers?

trying to loop through all the servers connected to bungee.

[eternal oxide]

ProxyServer.getInstance().getServers().getKeys()

[acoustic widget]

can you show me your code, it's intersting

[rugged topaz]

it's .keySet() right?

[eternal oxide]

probably

[rugged topaz]

yea, plus it's .values i'm looking for anyway but you pointed me towards the right path ty

[tardy delta]

uhh what do you want to see, its a big chunk of code

i just let all my classes extend a base class (GuiCreator) which implements InventoryHolder

[acoustic widget]

how you check if event is called by your gui

i had the same question when you was talking here

[tardy delta]

ah when making the inventory in the GuiCreator class, i pass this as InventoryHolder

[acoustic widget]

oh so you use holder too

ok ok thanks

[tardy delta]

and in the listener

[acoustic widget]

Nice thanks 😉

[tardy delta]

👍

only problem is my stupid navigation system which gave it up

[celest isle]

Anyone have any idea how to solve this error?

    public static class Dude extends EntityZombie {

        public Dude(World world, Player p)
        {
            super(((CraftWorld)world).getHandle());
            Location loc = p.getLocation();
            Dude dude = new Dude(((CraftWorld)world).getHandle());
            dude.setPositionRotation(loc.getX(), loc.getY(), loc.getZ(), loc.getYaw(), loc.getPitch());
            ((CraftWorld)loc.getWorld()).getHandle().addEntity(dude, CreatureSpawnEvent.SpawnReason.CUSTOM);
        }
    }

[tardy delta]

new Dude() :kekw:

[celest isle]

im talking about this lol

[tardy delta]

ah i see stackoverflow

[eternal oxide]

what is the error?

[onyx shale]

i see a bad casting

of asking a bukkit world

and giving it a craftworld

[celest isle]

its first time of me messing with nms and im confused

[eternal oxide]

yoru method wants a Bukkit world

[tardy delta]

Dude dude = new Dude()
-> Dude dude = new Dude()
-> Dude dude = new Dude()
...
you understand?

[onyx shale]

so only new Dude(world)

[tardy delta]

thats a stackoverflow no?

[celest isle]

I..

[tardy delta]

creating instances of itself in the constructor

[eternal oxide]

yes

[onyx shale]

thats alot of dudes

[tardy delta]

that's a whole army

[celest isle]

Jeez, never thought i need to write 10 lines of code to spawn a dude i can do from just 1 line

because its nms

[onyx shale]

well...

not rly..

[mint flare]

So, i don't find solution to left click who are not caught by the InventoryClickEvent
Do i have to search an other way to do what i need ?
Like verifying item when inventory is closed ?

[tardy delta]

whats even the point of making a new dude when making a new dude?

[onyx shale]

the dude needs another dude to have fun with

[tardy delta]

OOOOOHHH

[celest isle]

yep, i dont get it at all

[onyx shale]

well...

i would be honest and tell you that a java basic mistake but im too lazy rn

[celest isle]

yeah i know i gave the wrong world but

[onyx shale]

not that

the fact you created a infinite loop

[tardy delta]

Can't you just

public Dude(World world, Player player) {
  super(((CraftWorld)world).getHandle());
  setLocation(player.getLocation());
  ((CraftWorld)loc.getWorld()).getHandle().addEntity(this, CreatureSpawnEvent.SpawnReason.CUSTOM);
}```

Spoonfeed a newbie for a day and they'll come back with more questions. Teach them to find their own answers and you'll both be better off: you won't get stuck answering the easy questions and they'll be much more productive than before.

[quaint mantle]

Dude

[tardy delta]

smh that emoji sucks

[onyx shale]

but eh

[celest isle]

bruh

[onyx shale]

i guess when it comes to nms? we can close an eye

[tardy delta]

he probably doesnt know you can pass this as argument

[celest isle]

i legit dont

[tardy delta]

this is just the current instance with all methods and stuff

[onyx shale]

current instance wich is extending the entity hence why it accepts it btw...

[tardy delta]

true

ssh

[onyx shale]

just in case you think you can do this for everything😂

[celest isle]

oh i think i get it

[celest isle]

yeah i get this part

[tardy delta]

bug hunting for a week now...

[acoustic widget]

@tardy delta
I'm looking for add holders too,

e.getClickedInventory().getHolder()
return com.example.testmaven.gui.holders.MenuHolder

e.getClickedInventory().getHolder() instanceof MenuHolder
return false

here my holder

package com.example.testmaven.gui.holders;

import org.bukkit.inventory.Inventory;
import org.bukkit.inventory.InventoryHolder;

public class MenuHolder implements InventoryHolder {
    @Override
    public Inventory getInventory() {
        return null;
    }
}

Stange no ?

[gritty urchin]

How do I make a armorstand not lag behind when teleporting it every tick?

[onyx shale]

you dont do it through api

wich im sure your doin

you use packets

[gritty urchin]

How will that make any difference

[onyx shale]

whats the problem?

[celest isle]

when nothing is in /out 😔 🙏

[acoustic widget]

The problem is e.getClickedInventory().getHolder() instanceof MenuHolder return false even of true
When e.getClickedInventory().getHolder() = com.example.testmaven.gui.holders.MenuHolder

[onyx shale]

you mean teleporting a entity 20 times a second where the server has to keep track of replaced to non existing only for client?

[tardy delta]

cringe

[onyx shale]

are you passing a menuholder instance when creating hte inventory?

[acoustic widget]

Yes

[gritty urchin]

what so if I just send it to the client your saying it won't lag behind

[onyx shale]

and you are clicking the right inventory not the players one right?

[tardy delta]

oh french

[acoustic widget]

yes @onyx shale

🇫🇷

[tardy delta]

and if you try event.getInventory() instead of clickedinv

[onyx shale]

hmm whats with the specific package name?

[acoustic widget]

same

[acoustic widget]

import com.example.testmaven.gui.holders.MenuHolder;

[onyx shale]

is it the same as the one in create inventory?

check theyr definiton

[acoustic widget]

yes same

[onyx shale]

hmm should work

try putting a debug above the check

and see if it reaches the check

[acoustic widget]

Ok nevermind, i had to reload all entier server. I'm using biletool plugin for hot reload plugin when they are edited and seems to cause that bug

[onyx shale]

👍

[acoustic widget]

it works so

[little trail]

trying to understand concurrency with java and java CompletableFuture<String> future = CompletableFuture.supplyAsync(() -> { // some database connection return "Result of the asynchronous computation"; }).thenApply(result -> { System.out.println(result); return "Result of the then apply"; });
how would i get the result from this?

preferably not a blocking way to get it

[ivory sleet]

join

Then just use thenAccept

[little trail]

ah right

[ivory sleet]

Or if you want to chain it could use
thenApply where the function returns its argument

[little trail]

so do i not need thenapply?

[ivory sleet]

As said

thenAccept is viable

However it returns a CompletableFuture<Void>

Which does no longer contained the computed object

This if you want to chain more higher ordered functions after the future you might just use thenApply where the lambda passed return its argument

Since that’ll keep the computed object

[little trail]

oh so i cant get the object back out of it without blocking?

[ivory sleet]

Yes you can but you can’t await the result

Since that’ll block

So the only option would be a callback

[tardy delta]

should i cache inventory instances?

[ivory sleet]

Depends

[little trail]

i kinda want to extract the database connection, if its on the main thread and only occurs on startup i guess its fine?

[ivory sleet]

Extract the database connection?

[little trail]

well

i want the connection object stored in my class

wait what does thenapply do

[ivory sleet]

Pretty sure you can instantiate the connection pool and everything synchronous assuming it’s during bootstrap time. But then again queries, updates and retrievals from the database should be done async

it chains a Function<T,R> on to the future

Where the method returns CompletableFuture<R>

[little trail]

i honestly have no idea what R is

[ivory sleet]

R is the type parameter standing for resulting type

[little trail]

ah

so thenApplyAsync wouldnt let me get the connection from the future?

[ivory sleet]

Don’t use the async one

The future is already async

[rugged topaz]

are you able to grab the ProxyServer on a spigot plugin? ProxyServer.getInstance()

[ivory sleet]

If it’s from BungeeCord no

[little trail]

whats the difference between the async and non-async methods, do they do nothing in this context or are they just not different

[ivory sleet]

They’re very different

[tardy delta]

because they dont have an await, does that mean its a different thread?

[ivory sleet]

You often establish a CompletableFuture with CompletableFuture::runAsync or supplyAsync which will use a thread from the executor you pass along with the supplier or runnable (the executor is by default the common fork join pool). Assume you do call thenBlahAsync, basically it’ll just use another thread from the executor, so it’ll be async in relation to the already async task.

[ivory sleet]

Wym?

[little trail]

ah right

so the async one runs it again in a different task

[ivory sleet]

Await means you just wait for something to be done, in java we have Future::get or CompletableFuture::join for instance

[ivory sleet]

Yeah

Which in 99% of the times is unnecessary

[little trail]

tysm

wrapping my head around concurrency is hard

[ivory sleet]

Yeah it’s a bit weird at first

[mint flare]

I just don't understand why : https://youtu.be/8IIf9w0NWv0
why i can't put this lapis block in the backpack

Red message is in english : "Sorry, it's not the good item =("

normally, when i try to put an item in the backpack, the plugin will check if it's the same item that the item in first line and if not, the event is cancel

Inventory inv = event.getClickedInventory();
Player player =  (Player) event.getView().getPlayer();
ClickType type = event.getClick();
player.sendMessage(type.toString() + debug);
player.sendMessage(inv.getType().toString());
debug++;
if (type == ClickType.DOUBLE_CLICK) {event.setCancelled(true); return;}
        if (type == ClickType.LEFT && inv.getType() == InventoryType.CHEST && inv.getName().equals("§8Backpack")) {
            
            if (event.getSlot() < 18 || event.getCursor().getType() == Material.AIR) {
                event.setCancelled(true);
                return;
            }else {
                Team team = Team.getUserTeam(player.getDisplayName());
                Backpack backpack = team.getBackpack();
                int itemSlot = event.getSlot();
                System.out.println(inv.getItem(itemSlot-18));
                System.out.println(event.getCursor());
                              System.out.println(event.getCursor().isSimilar(inv.getItem(itemSlot-18)));
                if (!event.getCursor().equals(inv.getItem(itemSlot-18))) {
                    player.sendMessage("§cCe n'est pas le bon item... =(");
                    event.setCancelled(true);
                    player.updateInventory();
                    return;
                }else {
                    player.sendMessage("§a c'est le bon item, votre équipe marque un point !");
                    backpack.goalAchieved(itemSlot);
                    backpack.updateBackpack();
                    player.updateInventory();
                    team.addOnePoint();
                }
            }
        }

[hasty prawn]

Can you put anything in it?

I would imagine no

[mint flare]

Only (normally) the good item

[hasty prawn]

Whats the normally good item

[mint flare]

if you try to put an item in the first slot of the third line, the good item is the first item of the first line

[hasty prawn]

Oh I see

Change the if statement to use isSimilar instead of equals

[mint flare]

I didn't think it's the problem 'cause in the video, the click when i could put the labis block below the quartz block didn't catch by InventoryClickEvent 🤔

Otherwise, a message would have been send in the Minecraft chat

And i don't understand why this click is catch by the eventHandler
RAM problem maybe ? i put 2048 to max ram

[elfin talon]

 if (newlocation.getBlock().getState().getType() == Material.WALL_SIGN || newlocation.getBlock().getState().getType() == Material.SIGN_POST) {
                BlockState blockState = newlocation.getBlock().getState();
                Sign S = (Sign) blockState;
                
            }``` how can i set a line of the shield. It´s the version 1.12.2. S.setLine() doesn`t work with this code

[hasty prawn]

Nah, it was doing the right thing. It declined it because Lapis isn't Quartz. It only let you do it because the click type was probably wasn't Double Click or Left so it wasn't canceled.

[mint flare]

but in first instruction of the event there is :

ClickType type = event.getClick();
player.sendMessage(type.toString() + debug);
player.sendMessage(inv.getType().toString());

if this was an other click type, he should have displayed

[tardy delta]

if cancel becomes true, it should get cancelled no?

[hasty prawn]

Hm true that is a little weird

[mint flare]

the best solution, i think, is to change the way that the plugins works no ?
An idea is to let player put all he wants in the third line of backpack and when he close the inventory, i compare items
tell me if i'm wrong

[patent quarry]

Hey everyone ! I dont find the way to get the value of each pixel of a map. Is it possible to get them ?
I saw MapCanvas but idk how to get it

[rare minnow]

Hey, is there an event or way to detect vehicle collisions when ridden? e.g: Boat hits wall => action

Cause i've tried it (VehicleBlockCollisionEvent )and it only works if they do it by themselves

[opaque panther]

how to send images here

[ivory sleet]

verify

[opaque panther]

its not working

what should i type

when i tried it before it didnt send me any message in my soigot accoun

[rare minnow]

.?verify <Spigot.org username>

uh idk then

[opaque panther]

ok i verified

somehow it worked now

[ivory sleet]

pog

[ivory sleet]

unsure but this might require nms

[opaque panther]

anyway can someone help me, I can't select version in intellij spigot plugin settings

i saw other people do it

without error

why is it not working for me

[ivory sleet]

might have to re install the plugin

seems to be broken

[ivory sleet]

report thjat

but yeah

ensure u got the latest intellij version

and then reinstall that plugin

[opaque panther]

isnt 2021.2.3 the latest intellij

[ivory sleet]

idk

you can check urself I believe

[hasty prawn]

That's the latest version yeah

[opaque panther]

bruh i reinstalled the plugin and it still erro

[ivory sleet]

hmm you might wanna delete that spigot.json file

such that it can generate a new valid one

[opaque panther]

i cant find the location of the spigot.json

it says com.google.....

[ivory sleet]

Go and ask in their discord maybe

They should be knowledgeable about it tbf

[opaque panther]

i could only find the github. I posted an issue there a week ago

[ivory sleet]

no response?

[opaque panther]

the only way I could make a plugin was by asking another guy to give me a template

[opaque panther]

yea no response

[ivory sleet]

oof

[elfin talon]

hey i have an error java.lang.ClassCastException: class org.bukkit.craftbukkit.v1_12_R1.block.CraftBlockState cannot be cast to class org.bukkit.block.Skull (org.bukkit.craftbukkit.v1_12_R1.block.CraftBlockState and org.bukkit.block.Skull are in unnamed module of loader 'app') at tyko.de.haikobra.knockffa.De.HaiKobra.ranking.Ranking.set(Ranking.java:51) ~[?:?]

            skull.setOwningPlayer(Bukkit.getOfflinePlayer(UUID.fromString(rang.get(id))).getPlayer());
            skull.update();```

But when i import the material and the block i get the error: ```'org.bukkit.block.Skull' is already defined in a single-type import```

Who can help me with this error or has a suggestion?

[eternal oxide]

You setType on a BlockState, then you get a new BlockState and try to cast to Skull. It will not be a Skull as you never committed the change from the last state.

nm, ignore me, I was reading it wrong

However your LOC.get(i).getBlock().getState() seems to be returning a CraftBlockState, why?

it should be https://hub.spigotmc.org/javadocs/spigot/org/bukkit/block/BlockState.html

[young knoll]

CraftBlockState is the implementation

The bukkit one is only an interface

[eternal oxide]

yes, but that method shoudl return a BlockState not the implementation

[young knoll]

It does return a BlockState

CraftBlockState implements blockstate

[eternal oxide]

I wouldn;t expect to see his cast error on a BlockState

[eternal oxide]

Show us your imports

[elfin talon]

import org.bukkit.block.BlockFace;
import org.bukkit.block.Skull;
import org.bukkit.block.BlockState;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.UUID;```

[eternal oxide]

Yeah no clue, I'm tired and my heads not working.

[lavish hemlock]

who does this
tyko.de.haikobra.knockffa.De.HaiKobra.KnockFFA

[elfin talon]

its the main class

[lavish hemlock]

ye but don't you have to nest that in like two other fuckin' classes?

class De {
    static class HaiKobra {
        static class KnockFFA {

        }
    }
}

a new file is generated for every class ^

so that becomes De, De$HaiKobra, and De$HaiKobra$KnockFFA when compiled

which, I'm not entirely sure if this correct, but I believe De must be loaded if De$HaiKobra is

which means this approach causes two unnecessary problems:

• code size increase for redundant classes
• class load overhead for redundant classes

just like

[summer scroll]

what
