Hi! I am making a team system and I noticed that when I join, I can only see that I am on red team. But others can only see that they are on blue team. Turns out that this is because it creates a new scoreboard everytime someone joins the server. I decided to check this with the last if statement in the function and sure enough, it printed out the statement. Any suggestions for a fix? Thank you.

[arctic jetty]

i wonder why syncCommands() isn't called after a command is registered

any particular reason?

[ivory sleet]

I mean if it was called more frequently eventual lag spikes could occur if there’s a lot of players online and if it’s called on the server thread

[arctic jetty]

tru

[opal juniper]

laggy as shit but it kinda works

doing it in the worst way possible

[ivory sleet]

Holy

[opal juniper]

wait

[ivory sleet]

That’s cool

[opal juniper]

wrong vid

thats the right one ^^

[eternal oxide]

nice

[opal juniper]

what is the best way of moving the entity do you reckon elgarl

[quaint mantle]

how do i set an item's durability
i tried googling but theres nothing that shows an example

[round pelican]

Hello, is it normal that the only spigot maven dependency available for 1.17 is just "spigot-api" and not "spigot" ?

[ivory sleet]

Yeah

[opal juniper]

cause i am doing it in a really hacky and stupid way:

public void moveEntityToPlayer(Player player) {
    Location location = player.getLocation().clone();
    location.setY(location.getY() + 3);
    location.setX(location.getX() + 3);
    this.entity.teleport(location);
}

[round pelican]

oh okay, is it temporary?

and it'll be added later?

[ivory sleet]

Cast ItemMeta to Damageable

[quaint mantle]

uhhh how

[ivory sleet]

?learnjava

[undone axle]

Here are some links to get you started on learning Java:

• https://www.codecademy.com/learn/learn-java
• https://www.sololearn.com/learning/1068
• https://www.learnjavaonline.org/
• https://programmingbydoing.com/
• https://docs.oracle.com/javase/tutorial/java/index.html

The last one is the only official one, however some of those concepts assume that you already know a bit about programming.

[ivory sleet]

Well it’s available right now, no?

[eternal oxide]

Thats not bad as its probably the simplest. teleport will slide the entity

[quaint mantle]

ye i know how to cast but do u have an example

[opal juniper]

its the simplest for sure - i thought it would jerk it not slide hence the weird jumps

[eternal oxide]

I noticed a couple

[ivory sleet]

ItemStack stack = ...;
Damageable meta = (Damageable) stack.getItemMeta();

[round pelican]

wdym ? i was using the whole spigot dependency in 1.16, but then if I just use spigot-api in 1.17 i've got unresolved imports

[quaint mantle]

ahh like that

[opal juniper]

its just that the STEER_VEHICLE gives this data:

[ivory sleet]

Oh yeah it might not be stable enough to be published yet Mega my bad

[round pelican]

its fine np

is there an ETA for it being published?

[opal juniper]

i hoped it would be a dx, dz sorta thing

[ivory sleet]

Nope

[opal juniper]

but it is like the accelleration

[round pelican]

or an alternative fix ? like installing all the included dependencies by myself ?

[ivory sleet]

Hmm just use the spigot one which you got with build tools

[eternal oxide]

You could try applying velocities but at some point you would have to perform a location correction due to drift.

[round pelican]

okay so i just have to build a spigot jar and add it to my dependencies manually until the whole package is published on maven, right?

[ivory sleet]

Myeah

[opal juniper]

Hmmm - true

[round pelican]

okay well thanks for your help 🙂

[ivory sleet]

[quaint mantle]

HELP NEEDED: im using an essentials plugin for 1.17 and im trying to get it where regular players can use basic commands such as tpa and sethome and such and I cannot figure it out, gone to google and everything else and still nothing

[ivory sleet]

#help-server

[opal juniper]

@wraith rapids u around?

[lament bronze]

i mean you're not really supposed to register commands after the plugin was enabled

But I don't see why there isn't a way to do it without the server jar or reflection

[quasi flint]

Ur supposed to do it while it's being enabled

[lament bronze]

yes

[quasi flint]

luckperms

[granite stirrup]

does CommandMap.clearCommands()? clear all the commands that your plugin made?

or is it every command

[lament bronze]

every command

[granite stirrup]

f i just want to remove 1 command xd

[quasi flint]

A trolly thing. I see

[lament bronze]

access the knownCommands field

using reflection

and then remove it

its a hashmap

[quasi flint]

reflectiona

[quaint mantle]

um

[lament bronze]

xD

[quaint mantle]

luckperms?

[quasi flint]

Permissions plugin

So u can easily give permissions to groups of players like the default group

[granite stirrup]

where is that?

[lament bronze]

1 sec

[quasi flint]

https://luckperms.net/wiki/Home

[granite stirrup]

is it in CraftServer?

[quaint mantle]

thank you

[quasi flint]

Np

[lament bronze]

its in the SimpleCommandMap class

            final Field knownCmds = SimpleCommandMap.class.getDeclaredField("knownCommands");
            knownCmds.setAccessible(true);

            final HashMap<String, Command> knownCommands = (HashMap<String, Command>) knownCmds.get(commandMap);

this will give you an unchecked cast warning

but you can suppress it

commandMap would be your SimpleCommandMap instance

[quasi flint]

Why would u even want to remove a command?

[granite stirrup]

¯_(ツ)_/¯

just making something so i can

lol

[quasi flint]

;V

[lament bronze]

I'm working on a little plugin

Allows scripting

So I needed it

[quasi flint]

Just a trollplugin that removes all commands

And u register every listener

Can't go that wrong

[lament bronze]

ya know basically

[granite stirrup]

wait how would i get the commandmap for my plugin?

[lament bronze]

define some commands

[lament bronze]

1 sec

            final Field f = Bukkit.getPluginManager().getClass().getDeclaredField("commandMap");
            f.setAccessible(true);
            final SimpleCommandMap commandMap = (SimpleCommandMap) f.get(Bukkit.getPluginManager());

[sharp bough]

is it possible to create a
hashmap<UUID, hashmap<Integer,Long> = kits and kit = 3 (just an example)
take the player UUID, use
kits.containsKey(playerUUID)
and then check if kit is in the second hashmap?

[lament bronze]

the commandmap contains all commands

so you get the commandmap, then the knownCommands field from the commandmap

and then you can remove commands that are related to your plugin

or any other command if you really want to

[granite stirrup]

I've got an invisible armorstand that I want hovering over the player's head, but directly over their head while they move. As of right now, it more or less follows the player (about a 1/2 block behind) rather than sticking directly above them.

Is there a simple way to keep the armorstand directly above the player's head while they move?

[opal juniper]

i mean

are you listening to the moveEvent

[granite stirrup]

theres no knownCmds.remove

[lament bronze]

knownCommands.remove

knownCmds is a Field instance

[granite stirrup]

i have this knownCmds = SimpleCommandMap.class.getDeclaredField("knownCommands"); knownCmds.setAccessible(true);

[lament bronze]

look at the code again

there's an another line after those two

[granite stirrup]

?

[lament bronze]

in my code i sent

[granite stirrup]

but isnt that not gonna work

[lament bronze]

it is?

[granite stirrup]

its just gonna create a local variable?

[lament bronze]

wut?

final SimpleCommandMap commandMap = (SimpleCommandMap) f.get(Bukkit.getPluginManager());

its making a hashmap

its just getting the knownCommands field

wait wrong

one

this one

this line

final HashMap<String, Command> knownCommands = (HashMap<String, Command>) knownCmds.get(commandMap);

[waxen barn]

btw, i tried to make every vanilla command require at least op level 2, but it does nothing

                if (command instanceof VanillaCommandWrapper) {
                    CommandNode<CommandListenerWrapper> cmd = ((VanillaCommandWrapper) command).vanillaCommand;
                    LiteralArgumentBuilder<CommandListenerWrapper> builder = (LiteralArgumentBuilder<CommandListenerWrapper>) cmd.createBuilder().requires((p) -> p.hasPermission(2, "minecraft.commands.give") && cmd.getRequirement().test(p));
                    AddNodeChildR(cmd, builder);
                    VanillaCommandWrapper VanillaCMD = new VanillaCommandWrapper(server.getServer().commandDispatcher, cmd);
                    VanillaCMD.register(server.getCommandMap());
                    return VanillaCMD;
                }
                System.out.println(name);
                return command;
            });```

[quaint mantle]

yes

The problem is, it is about a 1/2 block behind the player

[waxen barn]

AddNodeChildR is btw

private static void AddNodeChildR (CommandNode<CommandListenerWrapper> cmd, ArgumentBuilder<CommandListenerWrapper, ?> builder) {
        for (CommandNode<CommandListenerWrapper> child: cmd.getChildren()) {
            ArgumentBuilder<CommandListenerWrapper, ?> childBuilder = child.createBuilder();
            AddNodeChildR(child, childBuilder);
            builder.then(childBuilder);
        }
    }

[granite stirrup]

but wouldnt that not effect the actual hash map or whatever it is?

[lament bronze]

...

but you want to remove a command?

[granite stirrup]

i want to remove a command

[lament bronze]

yes?

well then

[opal juniper]

show code

[lament bronze]

what's confusing you

I can try explaining it

All we're doing here is getting the commandMap which is an instance of SimpleCommandMap

then getting the knownCommands field of the commandMap which is a HashMap<String, Command>

the knownCommands hashmap is what actually holds the commands

[quaint mantle]

@opal juniper

        if (location.getX() == p.getLocation().getX()
                && location.getZ() == p.getLocation().getZ()) {
            return;
        } else {
            
            bounty.teleportBountyText(this);
            checkAndUpdateState(p);// Updates the state based on the player's position.
        }

^ Method that checks if the player has moved at all (I don't want to run this code when the player simply moves their screen)

    public void teleportBountyText(final NationPlayer nPlayer) {
        
        if(stand == null)
            return;

    }

^Code that teleports the armorstand

[lament bronze]

since it's a hashmap you can just remove/add stuff from/to it

[regal lake]

Is it possible that the buildtools don't work right now ?

Attempting to build version: 'java' use --rev <version> to override
Could not get version java does it exist? Try another version or use 'latest'

[granite stirrup]

so the hashmap there is a reference to the actual hashmap?

[waxen barn]

it would change also the original hash map, because in, java variables, that aren't primitive are just pointers to the data on ram

[lament bronze]

yeah that's how objects work

objects are always passed by reference

[opal juniper]

is it behind them when they stand still?

[quaint mantle]

no

only while moving

[granite stirrup]

they are i thought they weren't

[lament bronze]

👍

[opal juniper]

yeah

there is nothing you can do

unless u want to try and predict where they are gonna move

it is just it is only called 20 times per second max

which causes the delay

[quaint mantle]

I see

[calm whale]

Can anyone help me please ? #help-development message

[cold tartan]

how do you set motion in the direction you are facing? like i want an armor stand to move in a line in the direction it is looking, how would i do that?

[sharp bough]

is it possible to get the value of the key which is linked to another Key in a hashmap?
hashmap<Key, hashmap<Key, Value <-- what im trying to get>>

[quaint mantle]

Is there a way to make an armorstand "unhittable"?

[chilly compass]

hi! I want to teleport people from an Async task. I know that this isnt possible but is there a way to make it possible?

In my plugin the calculation of the location is kinda complicated and using this in a sync context it brings down my server to 18 tps. So it would be great if there is a way to do it

[quaint mantle]

I don't mean invulnerable.

[opal juniper]

call it in the scheduler

[quaint mantle]

Don’t use playermoveevent probably

[quaint mantle]

Wdym? If you have the first key then you have that hashmap

[chilly compass]

gonna try it, thanks

[quaint mantle]

Then same concept applies for the next hashmap

[opal juniper]

just bare in mind it wont be called until the next tick

[cold tartan]

stand.setMarker(true);

[quaint mantle]

No

setMarker - i'

I'

I'll give it a ttry

[cold tartan]

it just makes it so you can't interact with it

or u could check entitydamageevent

[quaint mantle]

Nope I think this is what I want

Thanks Defiant!

[chilly compass]

I dont care about that. But what does the scheduler do different than just putting it in my code? I saw that the tps were okay so there is a difference in some way

[opal juniper]

It will call it on the main thread the next tick

[sharp bough]

like that?

usign a buffer hashmap

that hold the value of the key

[chilly compass]

But isnt my event called in the main thread anyway?

[opal juniper]

U just said that u are doing stuff async right?

which means that it will not be on the main thread

[chilly compass]

Okay now I see

[cold tartan]

np

[sharp bough]

xd

saw it

[quaint mantle]

I mean yea that works

[granite stirrup]

i read it wrong

lmao

[sharp bough]

wait does this work
kitsUsed.get(playerId).get(kitID)

like is it a thing?

i cant test it

[granite stirrup]

maybe if you had a hashmap inside a hashmap HashMap<UUID,HashMap<Integer,Long>>

[sharp bough]

yea

[quaint mantle]

It should be

[waxen barn]

?

[quasi flint]

Dumb Question: Registered ze Code?

/ called it

[waxen barn]

yep, it is called 100 ticks after the plugin gets enabled

(originally it was 1 tick after it, but i tried to increase this number, but same result)

[dusk flicker]

You do know you need op lvl 2 to do commands arleady right?

The default commands atleast

Lvl 1 is just bypass spawn protection

[waxen barn]

nope, some commands as /me do't require op at all

[dusk flicker]

Well that's because it's a default permission

If you use a perm plugin just remove the perm for it if you dont want it to be run

[eternal oxide]

oddly you can't remove base MC command permissions

Well you can remove the perm but the command will still show in tab-complete and will be usable.

[dusk flicker]

Odd

[eternal oxide]

Bukkit commands you can, just not base MC commands

[waxen barn]

the code for modifieng the command is 100% working, because what i edit the command in command dispatcher, it works for the tab complete

but the registration isn't working

for (CommandNode<CommandListenerWrapper> cmd: ((CraftServer) Bukkit.getServer()).getServer().vanillaCommandDispatcher.a().getRoot().getChildren()) {
                 root.removeCommand(cmd.getName());
                 LiteralArgumentBuilder<CommandListenerWrapper> builder = (LiteralArgumentBuilder<CommandListenerWrapper>) cmd.createBuilder().requires((p) -> p.hasPermission(2, "minecraft.commands.give") && cmd.getRequirement().test(p));
                 AddNodeChildR(cmd, builder);
                 cd.a().register(builder);
             }

(^^^^ this works, but only for the tab complete, bec it doesn't affect the map)

[chrome beacon]

If you're doing this for a private server creating a patch could be easier

[waxen barn]

maybe, but it is usefull to learn how to learn how to register vanilla like commands, because many times before, i needed the better tab complete

[ivory sleet]

🥲

[cinder timber]

can you edit the server jar and fuck about with stuff

[earnest sonnet]

if you're brave enough

[opal juniper]

I mean - yeah sure you can

[granite stirrup]

i love this https://github.com/BepInEx/BepInEx

[arctic jetty]

which IDE is best suited for plugin development?

[cinder timber]

notepad++

[granite stirrup]

intellij or eclipse

[silk hamlet]

notepad++ gang wya

[arctic jetty]

i'm currently using eclipse but i wanna know the pros and cons of each ide

i also rarely see netbeans being used for plugin dev, any particular reason why?

[granite stirrup]

eclipse cons is shit ui and sometimes buggy
intellij cons is you have to really get used to that ui and its kinda hard to

[ivory sleet]

I use IntelliJ

Mainly because of UI

[silk hamlet]

Yeah

[arctic jetty]

i've used intellij before but it was kinda slow

[ivory sleet]

As slow as eclipse for me

[silk hamlet]

its performance heavy

intellij

for me eclipse is fater

[granite stirrup]

i think intellij uses electron

[silk hamlet]

faster

[arctic jetty]

lol that explains it

[ivory sleet]

I don’t think so

Why would it

Maybe webstorm does

[unreal quartz]

lol what? it's a native java app

[arctic jetty]

o

[unreal quartz]

intellij's performance depends on your disk speed mainly, otherwise you're gonna be sat there for 5 minutes waiting for it to index

[ivory sleet]

IntelliJ probably caches a lot more stuff like the indexing it does for instance

[waxen barn]

intellij idea

[arctic jetty]

lol since i've heard intellij so much i'll try using that instead of eclipse and see if it's better or not

[unreal quartz]

because most people here use IJ

[ivory sleet]

Better is very subjective

[arctic jetty]

better for my purposes*

[ivory sleet]

Mye

[opal juniper]

Looks nicer - IntelliJ

Imo

[ivory sleet]

Handles kotlin better - IntelliJ

[arctic jetty]

holy damn it's pretty slow

[ivory sleet]

You can set a higher max ram allocation limit

[opal juniper]

I mean they made the Lang didn’t they?

So I would expect it

[waxen barn]

yep, they did

[ivory sleet]

That’s why it’s so good /s

[waxen barn]

even it was made for them to make it easier to develop intellij idea

but personally, i don't like kotlin so much

[ivory sleet]

I will convert if it gets union types

[sharp bough]

is there a better way to do this: https://paste.md-5.net/ikuheyicix.m
i already tried https://paste.md-5.net/yinihoweki.m but i get a few errors

HashMap<UUID, HashMap<Integer, Long>> kitsUsed = new HashMap<>();

im trying to add values to the second hashmap inside that hashmap

[ivory sleet]

You might wanna adjust the load factor

[sharp bough]

whats a load factor

[ivory sleet]

Also for the record Tables would help you abstract away the awkwardness of nested maps

[waxen barn]

you can create own class and store there the kitID and the time

[ivory sleet]

Lucas a
Table<UUID,Integer,Long> is equivalent to Map<UUID,Map<Integer,Long>>

Only difference is that it automate creations and destruction

Myeah I guess it’s good if you need type erasure

[sharp bough]

tf is a table and why cant i find docs about it

[ivory sleet]

Guava

Table<R,C,V> table = HashBasedTable.create();

[grand coral]

How can I get the fields in Crafting Table (items in fields)

[ivory sleet]

Probably through CraftingInventory

[whole stag]

Is just generally better - vscode

🙃

[hexed hatch]

Is there any way to inject a basecomponent into a chat message?

I know I could cancel the event and create my own chat system but that's a last resort since there are other plugins at work

[ivory sleet]

[hexed hatch]

That'll work? I thought that only supported strings

Nope

Not working

[granite stirrup]

i thought it uses electron

[hexed hatch]

I tried converting it to legacy but that doesn't preserve the hover or click events

[granite stirrup]

some dickhead dmed me a scam discord

pretty sure its a scam

[hexed hatch]

How do I even get the message as components?

I'm just using the AsyncChatEvent

Oh, I think you're thinking of the Paper chat event

Man, that looks a hell of a lot better

Time to use the paper api instead

[arctic jetty]

isn't the paper api pretty much the same as the spigot api?

[untold gazelle]

^^

[hexed hatch]

Not the AsyncChatEvent

[arctic jetty]

ah ok

[untold gazelle]

ah ok

[hexed hatch]

Paper API adds a lot of shit and adds a lot of events

[digital plinth]

are datapacks just a bunch of in-game vanilla commands?

i dont see how commands like /summon zombie can be packed into a java class

[maiden thicket]

why not

[digital plinth]

okay then lol

[obtuse basin]

Is there a way doing custom textures for own blocks and items?

[waxen barn]

yep, resource pack

but for blocks, you must use some block, that already exists

for item, you still must use some existing item, but you can set its custom model data nbt tag, so this texture won't be obtainable ingame

[young knoll]

Noteblocks and mushroom block are good choices

As they have a ton of unused states

[waxen barn]

or logs if you need to make it rotateable

[obtuse basin]

Hmm, cant I just use some NBT and make that the texture only gets applied with that NBT Tag?

[waxen barn]

yep, but blocks can't have custom nbt tags

some have, but you can't define your own including custom model data

[obtuse basin]

there was some funiture plugin used spawn eggs for placing funiture, it doesn't needed the textures installed on client

[waxen barn]

this uses invisible armorstands with blocks on heads

it can't use custom models, bec op saied, that there were no texture packs on the client

[waxen barn]

for example this plugin https://www.spigotmc.org/resources/✈️vehicles-no-resourcepacks-needed.12446/ uses the same thing

[opal juniper]

They are armour stands iirc

And yes

The big models were laggy

[waxen barn]

and problem is, that minecraft doesn't have any link between entities that supports offset in all directions

so you must send packet for each armor stand when you want to move them

oh, i didn't know this, thx for correcting me

[compact haven]

wait what the hell?

that literally makes no sense kekw

[whole stag]

Makes sense to me

[waxen barn]

why?

[whole stag]

You need to keep the state of the server and client in state

[winged ridge]

Hello, I am making a plugin in Java for my minecraft server, basically it spawns a custom sword inside a chest and when a player opens it, it gives him effect, I'm having some issues with trying to prevent players from re-having effects when opening the chest multiples times, I've tried putting player names into a HashMap which worked but I needed to make the HashMap permanent so I tried converting its data to a JSON then getting it back after a reload, but that didn't work.
Is there any other way I can let a user have effect only one time when they open a chest and then no effects when they re-open it?

btw I already set the plugin to check if the chest contains the custom item, so that not all chests get the effect.

[waxen barn]

but any packet loss (and this will probably not happen) will be corrected on net entity movement, so there won't be any serious difference anyways

[whole stag]

Kinda, but not really

There's no foolproof way of detecting package loss

[waxen barn]

based on if it is private server or public plugin

for private server, I'd go with MySQL, for public plugin, save it to binary file

[clear galleon]

persistentdatacontainer?

[winged ridge]

It’s a private server, so you’re saying I need to store players name in a MySQL database ?

[winged ridge]

What is that?

[clear galleon]

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

idk if its the right use case but i think it can get the job done

[waxen barn]

I recommend more storing UUIDs, because when premium player change his name, the data will still be there

[winged ridge]

So if I understand, this is like a HashMap or a List, that can store data permanently

[waxen barn]

thats also option to use nbt tags, but idk if they reset when the player reconnects

[clear galleon]

does not reset upon anything im pretty sure

[dusty sphinx]

Is there a place to read the BungeeCord javadocs?

[ivory sleet]

Yeah a map like structure

[dusty sphinx]

Thanks

[waxen barn]

it is simply object, that allows plugin to edit nbt tags

[glass sparrow]

How come?

[dusty sphinx]

Is there a list of Bungeecord API versions?

[ivory sleet]

Check the repo

[winged ridge]

I’ve never used MySQL so I might try persistentdatacontainer first

[clear galleon]

yeah i dont see whats wrong with using it

[winged ridge]

But MySQL can work for only stocking UUIDS?

I thought it was for bigger things

[ivory sleet]

I mean use pdc if needed, it’s very context dependent whether it’s a bad or good solution to a problem

[waxen barn]

it is database, so you can store there almost anything you want, you need to create a table there, that contains columns, each column has some datatype and then each row is some players data in this case

[waxen barn]

so it has a pro, that you can also add money, ....... there

con is, that you must setup the database server

[ivory sleet]

If you can, use something like mariadb or postgre

Reinventing the wheel without any significant justification is probably somewhat naive yeah

[compact haven]

uhm you're saying I shouldnt recode minecraft because I dont like how it works?

[ivory sleet]

🥲

[compact haven]

ignorant fellow

[ivory sleet]

[winged ridge]

Hmm I think I will try persistent data containers then

Seems easier to set up

[ivory sleet]

I am sorry but I haven’t joined kkk yet and will probably not do that unless I get a zillion dollars or something

[compact haven]

yet and probably not

im not very satisfied with your answers

[dusk flicker]

yet

[compact haven]

dig a hole and bury yourself please

[dire marsh]

dig a whole

[compact haven]

yes a whole hole

i only fixed it because I thought it was too wordy

sorry but I know the CEO

and COO

and CFO

anll the CO's

and you arent oen

oh

oh

[dusk flicker]

NNY how many NNY accounts for you have

[dire marsh]

md banned like 6

[ivory sleet]

Did he? Lol

[dusk flicker]

Lmao

[dire marsh]

or kicked, not sure

[ivory sleet]

He hasn’t been banned on a single nny account

[compact haven]

every combination of NNY with 17 characters after is owned by him

[ivory sleet]

lol

[dire marsh]

but why

[compact haven]

including every discriminator, so NNYaKNpGms0eUVpiSdHx#5618, NNYaKNpGms0eUVpiSdHx#5619, NNYaKNpGms0eUVpiSdHx#5620, etc

[ivory sleet]

Lmfao

[compact haven]

lmfao

[shut field]

how can I cast an Inventory to an InventoryView?

[clear galleon]

inventoryview contains inventory

[ivory sleet]

You don’t cast it

[clear galleon]

for example #getInventory or #getBottomInventory

[shut field]

I have an Inventory but I am trying to get it's title/name

and to my knowledge you need an InventoryView to get it's name?

[ivory sleet]

Yes

Legacies have the title attached to the inventory itself

[shut field]

Legacies?

[ivory sleet]

1.8

For instance

Legacy version

[granite stirrup]

Wait pretty sure on 1.16 you can get the title by the inventory

[shut field]

okay but I am not using 1.8 I am using 1.17

[ivory sleet]

Then InventoryView

[shut field]

how to turn the Inventory to an InventoryView was my question

[clear galleon]

Did you create the inventory>

?

[shut field]

InventoryCloseEvent -> getInventory()

oh your right, thank you

[cold tartan]

could someone help me with this?

[cold tartan]

this

[granite stirrup]

setVelocity I think

[next stratus]

There should be a way to hire devs here ngl

[tired dagger]

I believe you can use PlayerVelocityEvent then setVelocity()

[cold tartan]

the way i set motion for the player:

player.setVelocity(player.getVelocity().add(player.getLocation().getDirection()).multiply(5));

isnt working for an armor stand , but im not sure why

[next stratus]

I mean, there should be a channel for it

[cold tartan]

but there could be like a role

like "Up for Hire"

[next stratus]

Like I gotta find someone else to help me fix some things

[cold tartan]

what do u need help with?

[next stratus]

I am rewriting a mines plugin I paid for

[cold tartan]

this one? https://www.spigotmc.org/resources/mines-»-1-7-1-17-•-unique-features-•-api.63552/, or something similar?

[next stratus]

And I am struggling with some things like the upgrading part

Nah another, want me to grab link?

[cold tartan]

is it similar in complexity tho?

[next stratus]

You can say that yes

Yes

I think it's 2mb

[cold tartan]

3 - 4 mb

[tired dagger]

What is your code for the armor stand?

[cold tartan]

the exact same, just for an armor stand

[next stratus]

Wait, there's a limit on file size?!

Oh crap.

[cold tartan]

according to this:
https://www.spigotmc.org/threads/spigot-max-file-size.309075/

but u can link like a dropbox

[next stratus]

I'll sit on it and squash it down

[cold tartan]

🧠

[cold tartan]

u r big brain

[tired dagger]

Hmm. Maybe try launchProjectile? https://hub.spigotmc.org/javadocs/spigot/org/bukkit/projectiles/ProjectileSource.html#launchProjectile(java.lang.Class)

[granite stirrup]

F well hope my plugin doesn't go over 3mb

Rn it's like 20 something kB or idk something like that

[cold tartan]

that will just launch a projectile from the armor stand

[tired dagger]

Ah, nvm then

[dusty sphinx]

This is probably way, way beyond the scope of this channel, but can anybody point to some good resources on learning SQL commands? Trying to get into SQL messaging but I'm not quite sure where to start.

[quaint mantle]

Any events for when a player changes the item in their hand?

PlayerItemHeldEvent

Found it 🙂 thanks

Or is that only when they change slots? Guess I'll have to test it to find out. I'll reply if it works or not.

Ah it only seems to fire when changing slot

Would you say the only way to do it is to make my own events for InventoryClickEvent, PlayerDropItemEvent, etc

not own events but check inside of them events

[tired dagger]

I'll do some testing when I get back; I'm going to eat dinner atm

[cold tartan]

np, i messed arround with it a bunch and couldn't get it to work so i decided to use an arrow instead

now that im thinking about it the arrow was better for what i needed anyway

[candid galleon]

hey guys

is there any way to generate a book from json, like with the /give command?

eg: {pages:['{"text":"Minecraft Tools book"}'],title:Book,author:"http://minecraft.tools/"}

[whole stag]

Yup

[idle tulip]

?

[hollow pasture]

A question, I have this code from version 1.16 but when I move it to version 1.8.8 the code comes out with an error. Bukkit.getServer().getScheduler().runTaskLater(plugin, (bukkitTask) ->

[glossy scroll]

That API did not exist in 1.8.8

[shut field]

what is List<?> def

(I use it after a getConfig() )

[compact haven]

its just the default parameter

u dont need it pretty sure

[waxen barn]

where did you find the source of this function, I am trying to find it, because I need to look at what it is doing, but I don't see it anywhere

[shut field]

correct, it is optional, but I was wondering if anyone knew what it's use is

I am also wondering how you can get an ItemStack[] from a config file

[hollow pasture]

and What is the best way to do it? Can you help me?

[glossy scroll]

I cant help

[tired dagger]

https://minecraft.tools/en/book.php

[candid galleon]

i want to do it in source

i have the json, i need to convert it to a book without the give command

[glossy scroll]

bookmeta.spigot()

[candid galleon]

the only method I see is deprecated

[candid galleon]

right? that supports basecomponents

[glossy scroll]

yes

[candid galleon]

how would i convert json to basecomponents then?

[glossy scroll]

https://javadoc.io/static/net.md-5/bungeecord-chat/1.16-R0.4/net/md_5/bungee/chat/TextComponentSerializer.html#deserialize-com.google.gson.JsonElement-java.lang.reflect.Type-com.google.gson.JsonDeserializationContext-

@candid galleon actually

Use this

https://javadoc.io/static/net.md-5/bungeecord-chat/1.16-R0.4/net/md_5/bungee/chat/ComponentSerializer.html#parse-java.lang.String-

ComponentSerializer.parse

[candid galleon]

interesting

so I'd have to manually support the author/description/title

[glossy scroll]

Which json exactly do you refer to?

[candid galleon]

both

since BookMeta.Spigot only supports component page

[glossy scroll]

nono

The text of the book

Or the book itself

Because there is a way to deserialize items, i just forgot where the method is

[candid galleon]

i want the book itself

which includes the text

[glossy scroll]

This is the closest i could get

https://www.spigotmc.org/threads/deserializing-itemmeta-from-json.69760/#post-771247

[candid galleon]

gross

i think i'll just use the deprecated method

ty for the help

[glossy scroll]

?

Whats that

[candid galleon]

Bukkit.getUnsafe().modifyItemStack(book, json);

[glossy scroll]

Its only deprecated because it may not be safe in the future

[compact haven]

oh my

getUnsafe and deprecated

[tired dagger]

Ah, well I did some testing anyway and it worked for me. Here's what I used. entityPlaceEvent.getEntity().setVelocity(entityPlaceEvent.getEntity().getLocation().getDirection().multiply(1.5));

[cursive glen]

Hello1

Need help with getting a player by number with Bukkit

So basically

Player p = Bukkit.getOnlinePlayers()[player_num];

doing something like this

[tired dagger]

I don't understand your question. Are you trying to assign all the online players individual numbers?

[shut field]

how do I get an ItemStack[] from a config file

[tired dagger]

https://bukkit.fandom.com/wiki/Configuration_API_Reference#Getting_Values

[shut field]

but

there is no getItemStackList

[tired dagger]

Show me the values you want from the config

[shut field]

it is just a list of items

[tired dagger]

getItemStack()

ohh, but as a list

[shut field]

ye

[tired dagger]

Mmm, one sec

You may just have to use a loop and add them to a List of type ItemStack

[compact haven]

ok so say I have a custom library, and 2 plugins on the server shade it, would they both have separate instances of it or would it be 1 instance

[cold tartan]

ty!

[compact haven]

if I dont relocate ^^

[tired dagger]

YW!

[tired dagger]

No idea but I assume separate instances

[shut field]

how do I loop through those values

[tired dagger]

a for loop

or for each

[shut field]

well yes that

[tired dagger]

Haha

[shut field]

do I just set an ItemStack to the "getItemStack" and then loop through that?

[tired dagger]

I believe you so

Just make sure you're adding the values to a list so you can iterate through them later

[tired dagger]

Mm

That's unfortunate

Let me think

[shut field]

also don't ItemStacks usually only contain 1 value?

how can it also store a list of them?

[shut field]

what should I do with that

[quaint mantle]

how can I also store a list of them?

[tired dagger]

That's the list you will add the values to. Now just gotta figure out how to grab the values

[quaint mantle]

@shut field what are you trying to do

[shut field]

and this is the config file

I am trying to make a backpack system using a config file

[shut field]

but I don't know how to grab (and use) the info saved in this

[quaint mantle]

get the list of itemstacks from the config

[shut field]

how? there is no getItemStackList

[quaint mantle]

FileConfiguration config;
String path;
// ...

List<ItemStack> itemStackList = (List<ItemStack>) config.getList(path);

[tired dagger]

Ah, so that's how you grab the path list. That's what I was trying to do

[shut field]

what is "(List<ItemStack>)"

[quaint mantle]

?learnjava

[undone axle]

Here are some links to get you started on learning Java:

• https://www.codecademy.com/learn/learn-java
• https://www.sololearn.com/learning/1068
• https://www.learnjavaonline.org/
• https://programmingbydoing.com/
• https://docs.oracle.com/javase/tutorial/java/index.html

The last one is the only official one, however some of those concepts assume that you already know a bit about programming.

[shut field]

well less of "what is it" and more of why would you use it there

[quaint mantle]

to cast it

[tired dagger]

It's an List of the ItemStack type

[shut field]

but isn't it just set before that, why does it need to be casted right after decleration?

[quaint mantle]

because it's a wildcard <?>

[shut field]

ohhhhhhhhh

I get it now, I was confused by the indentation

List<ItemStack> itemStackList = (List<ItemStack>) config.getList(path);

that is all 1 line!

[quaint mantle]

it wasnt indented?

[shut field]

I thought these were two diffrent lines:

List<ItemStack> itemStackList = (List<ItemStack>)

config.getList(path);

[quaint mantle]

no

[shut field]

cause I see this:

[quaint mantle]

what client are you on

[shut field]

non-fullscreened discord

I know how to cast stuff, I just was confused by the indentation (that my minimised discord caused)

[cursive glen]

something like that

Basically I would like to add all the players to a listr

list**

and get the player by doing list_name.get(1)

and then having that be a player object

[silk mirage]

Hm

How about you store serialized data

[quaint mantle]

Any other events to do with items which I can check the changing of an item in a players hand?
https://paste.md-5.net/upowevezum.java

whats your original problem @quaint mantle

Nothing, just asking if theres any more events I need to check for an ItemChangeEvent

when do you want it to be called

When a player swaps items the event ItemChangeEvent will be called

And I checked, no event for that so may as well just make it

[tired dagger]

So, you can get a list of all players like this and go through one using a for each loop. Or you could just use the .get(0) if you only wanted the first entry

List<Player> onlinePlayers = new ArrayList<>(ERInstance.getServer().getOnlinePlayers());

for (Player player : onlinePlayers)
    player.sendMessage("Hey");

@quaint mantle That would work too. I'm not familiar/comfortable with lambdas yet so my code is a little more expanded

[quaint mantle]

Isn't it .get(0) for the first entry?

@tired dagger

[tired dagger]

True

[quaint mantle]

true != true

[tired dagger]

You caught me

!false

[quaint mantle]

!true

!!!!!!!!!!!!!!!!!!false

ezW

[tired dagger]

!(0)

[quaint mantle]

oh no

[tired dagger]

xD

[quaint mantle]

lmao

[tired dagger]

Gotta love programming language

[fair island]

how do i compile a jar (Im trying to get PlotSquared V6)

[quaint mantle]

add the extension .jar to the file

[fair island]

to the ZIP? @quaint mantle

[quaint mantle]

yes

no

instead of .zip make it .jar

thats not how it works

[fair island]

uh

[quaint mantle]

@dusty herald enlighten this man

download the zip, then compile the contents using gradle (since its a gradle project)

[summer scroll]

Does Citizens NPC count as Player object? Like If I cast (Player) onto the entity will it cause errors?

[fair island]

I have gradle downloaded, its a zip and idk how to use it

may have figured it out on the gradle thing

hold on

[dusk flicker]

Use Spigot

[fair island]

ok so i got gradle, Now how do i use it

[candid galleon]

EntityDropItemEvent is very poorly named

makes me think it's a more up to date version of PlayerDropItemEvent

[fair island]

when i click the Gradle.bat it says build failed

[fair island]

I can't get gradle to work :/

im trying to compile it

[tired dagger]

@ivory sleet @opal juniper @jade perch @summer scroll I have absolutely no idea what happened but after trying to figure out the ACF Command API for an hour I gave up and deleted it. I literally typed the same code from last night and decided to test it for the hell of it and it worked...

[forest path]

Is it possible to increase the time it takes for copper to weather?

[tired dagger]

Probably

I'm going to assume it has an NBT tag named "Age" or something that gradually increases and once it gets to a certain age the block state changes (similar to how a baby entity transforms into an adult as it gets to a certain age). This is just a guess though.

Actually, a block is not an entity so probably scratch that

[summer scroll]

Maybe you can start by debugging what event is being called when copper is weathered?

Although i'm not really sure how that works because it's new.

[compact haven]

"debugging what event is being called when copper is weathered"

do you exactly know how many events are called a tick

[summer scroll]

lots of event

[torn frost]

Hi when i set soft dependency of multiverse for my plugin?
do i set it like this :
softdepend: [MultiVerse]

I mean the name...

[compact haven]

go onto your server

do /plugins

find multiverse and copy the exact characters of the plugin name from /plugins

to the softdepend array

[summer scroll]

I believe it's Multiverse-Core iirc, you can check them using /pl command.

[torn frost]

ohh its same as in pl list ok

ty....but sometimes it runs before multiverse finishes the loading custom worlds

[deep tiger]

Do you know if it is possible to change this message ?

[summer scroll]

There is one way that I found how to increase the speed, it's by increasing the randomTickSpeed but I don't recommend it, since it will affect other things aswell.

[tired dagger]

I think that is hard-coded into the game but I may be wrong

[deep tiger]

it is very possible as it comes from brigadier i believe 🤔

[mystic tundra]

So I have the value and signature of a player’s minecraft skin, how would I overlay part of another skin .png texture over that? For example, if I want everyone’s skin to wear a hat on my server, I have the hat as the skin texture file with evertything but the hat erased

[quaint mantle]

Trying to recreate some of hypixel's uhc things but rn im trying to make a recipe book? is there any way its easier than to give ALL the materials even the air ones? this is my code rn:

public class RecipeInventory {
    public static Inventory newInv(Material[] mats, ItemStack result) {
        ItemStack clearGlass = new ItemStack(Material.GRAY_STAINED_GLASS);
        clearGlass.getItemMeta().setDisplayName("");

        Inventory inv = Bukkit.createInventory(null, 53);
        inv.all(clearGlass);
        // ROW 1
        inv.setItem(11, new ItemStack(mats[0]));
        inv.setItem(12, new ItemStack(mats[1]));
        inv.setItem(13, new ItemStack(mats[2]));
        // ROW 2
        inv.setItem(20, new ItemStack(mats[3]));
        inv.setItem(21, new ItemStack(mats[4]));
        inv.setItem(22, new ItemStack(mats[5]));
        // ROW 3
        inv.setItem(29, new ItemStack(mats[6]));
        inv.setItem(30, new ItemStack(mats[7]));
        inv.setItem(31, new ItemStack(mats[8]));
        // RESULT
        inv.setItem(24, result);

        return inv;
    }
}

[mystic tundra]

Is tgere a way to get a .png from a value and signature, overlay two .pngs and then get the value and signature of the final .png?

[mystic tundra]

This us the first part of my message

[tired dagger]

Actually. I just joined a semi-big server to do some testing and you might not be able to necessarily replace the message itself but it seems you suggest a tab completion.

So in a way, you can

[mystic tundra]

So if anyone could help me I would appreciate it

[deep tiger]

Yes but I believe that you can suggest a tab completion only after typing the command name

[tired dagger]

Yeah, you could loop through the materials list

[quaint mantle]

idk how lmao

[tired dagger]

Right, but that message only shows up when you type something invalid. What I typed was invalid

[quaint mantle]

Would be nice if u could just Turn a shaped recipe into an inventory

[deep tiger]

I know but i would like to show it even if the sender didn't add any argument

[tired dagger]

Like?

/command

[deep tiger]

yes but without any argument

just the command name

[quaint mantle]

you can

[deep tiger]

so that when he started to type the command name he receive a custom tooltip

[quaint mantle]

like this?

[deep tiger]

I know but i would like to do the same without any argument

[quaint mantle]

i didnt type anything and it just shows that

[quaint mantle]

Oh for commands?

[deep tiger]

yes

[quaint mantle]

just press tab

and find ur command

[deep tiger]

No but what if i type an unknown command ?

I would like to change this message

[quaint mantle]

wdym?

[deep tiger]

I would like something like that

[quaint mantle]

what do u want after that?

[tired dagger]

Literally what I sent xD

[deep tiger]

Oh sorryy but i don't know how to that x)

i already dit it with arguments but it doesn't work when you just type the command name

[lament bronze]

https://hub.spigotmc.org/stash/projects/SPIGOT/repos/craftbukkit/browse/src/main/java/org/bukkit/craftbukkit/CraftServer.java

Line 436

[tired dagger]

Use PlayerCommandPreprocessEvent

[quaint mantle]

but then i would have to make my recipe abcdefghi

is there an easier way

[opal juniper]

😄

[quaint mantle]

so i can just get the letters

[deep tiger]

This event fires only when the player hit the enter button

[tired dagger]

Oh yeah, that's right

[fair island]

I can't get gradle setup and I need to compile a plugin, someone help

[opal juniper]

What are you trying to do

[deep tiger]

I'm trying to remove this message

I'm trying to change or to remove this message when a player starts typing an unknown command

[opal juniper]

Can you? Afaik you would need to register it or do some packet fucknuggetry

[lament bronze]

pretty sure that's clientside

[opal juniper]

What makes you say that?

[lament bronze]

you gotta sync commands

the client doesn't know about any command until you sync

why would it do a packet to get a command on every keystroke

[opal juniper]

Right - well I imagine that there are packets sent about it yes

Idk if it stores a registry of commands

@deep tiger do you know what a directed graph is?

[deep tiger]

Nop :/

[opal juniper]

Clientbound packet ^^

[deep tiger]

Yes i've seen this too !

[lament bronze]

well thats what sync does i'd imagine

[quaint mantle]

// ROW 1
        inv.setItem(11, recipe.getIngredientMap().get('A'));
        inv.setItem(12, recipe.getIngredientMap().get('B'));
        inv.setItem(13, recipe.getIngredientMap().get('C'));
        // ROW 2
        inv.setItem(20, recipe.getIngredientMap().get('D'));
        inv.setItem(21, recipe.getIngredientMap().get('E'));
        inv.setItem(22, recipe.getIngredientMap().get('F'));
        // ROW 3
        inv.setItem(29, recipe.getIngredientMap().get('G'));
        inv.setItem(30, recipe.getIngredientMap().get('H'));
        inv.setItem(31, recipe.getIngredientMap().get('I'));
        // RESULT
        inv.setItem(24, recipe.getResult());

made it like this but then i would have to make the recipe each slot an different key
how would i do that

how to fix*

[deep tiger]

Means we can't do anything right ?

[opal juniper]

U could send it urself

[lament bronze]

but how does that achieve the result of removing the error message?

removing/editing

[opal juniper]

Cause if he registers the command - it isn’t invalid

Thats my thought process anyways

[lament bronze]

but how do you know what command the user is currently typing out

i'm 99% sure its client side

[deep tiger]

The idea is : when he started typing, we sent him a custom packet with the command he is typing ?

[lament bronze]

because something like that doesn't really make sense to be server side

[lament bronze]

But how do you detect the typing

[deep tiger]

No idea x)

[lament bronze]

Well yeah

You can't

that's the problem

[deep tiger]

But some servers can do that

[lament bronze]

<args> is a default thing

after you type a command it shows <args> if you haven't declared what each argument is

[deep tiger]

mmh

[tired dagger]

@deep tiger I think I'm onto something here 🤣

[hardy swan]

That's honestly the best thing to see while debugging

[tired dagger]

Fax

[lament bronze]

that's tab complete

he's asking for the popup help thing

[tardy delta]

huh

[tired dagger]

Yeah, since the pop-up message can't technically be replaced, you could override it with tab complete

[lament bronze]

don't think how that works

but if you can do it then gg ig

[tired dagger]

Like so:

[deep tiger]

How did you come to this result ? x)

[opal juniper]

he said

Yeah, since the pop-up message can't technically be replaced, you could override it with tab complete

[tired dagger]

I haven't yet

I went on a semi-big server (bc they usually have good devs that know how to block things) and did some testing to see if they were able to do it

[lament bronze]

but that's not the wanted result

:/

<args> cannot be changed

[tired dagger]

Why you say that?

[lament bronze]

because it can't be removed?

[tired dagger]

[patent spoke]

I want to spawn a Villager at predifined cordinates, but i dont know how to set them in code. Can someone help me?

[tired dagger]

How do you want the Villager to spawn? Command?

[patent spoke]

No when the server starts the Villager should spawn

[tired dagger]

I mean like for initial setup

But ig you could just do that

Well, @deep tiger I tried but am not sure it is possible. This is the closest I could get. The errors suggest both packets and brigadier are in use so yeah... 😦

[hybrid spoke]

"playerAvailableCommands" is null

[tired dagger]

I know but the error still suggests aspects that are out of my control so it seems pointless to keep pursuing it

[subtle kite]

fix the null part

and then if it doesn't work

¯_(ツ)_/¯

[hybrid spoke]

¯_(ツ)_/¯

giving up: the best solution for your problems

[tired dagger]

Didn't give up, I ran out of options.

[mystic tundra]

Whats the mojang website which has all the player skins, that you can search by the skin signature?

[lament bronze]

btw i just wanna add a thought on this

if the base server is 1.8 and you can join with a 1.13 or later then the auto complete won't exist at all

and will only show <args> for every command

[deep tiger]

Thanks to thank you very much for trying 😉

[lament bronze]

because the base version is under 1.13

[tired dagger]

You're welcome 😉

[deep tiger]

Very true

[lament bronze]

if that's not the case then they just don't have auto complete on the commands

[mystic tundra]

There should be a textures.minecraft.net/textures/enter signature here and it should give you the skin

Anyone know where minecraft stores the skin files? I have a player’s skin’s signature and value and I’d like to download their skin

For a plugin I’m making

[quaint mantle]

still dont know how :(

[waxen plaza]

Can someone explain what owner means and what it does?

[chrome beacon]

Who's holding the inventory. For example if it's a player inventory

[waxen plaza]

Does it behave different if I make it either null or a player?

[chrome beacon]

Not sure but you can just set it to null

[summer scroll]

It's basically an inventory holder, it will return that object if you try to get the holder by using Inventory#getHolder

[waxen plaza]

ohh, I store the inventories in a database and I set owner to null but I use the player uuid's to find them later

I quess it doesn't matter then

[summer scroll]

yup, it doesn't really matter

[tardy delta]

should this play a timer for the player?

    private void startReadyCounter() {
        Bukkit.getScheduler().runTaskTimer(plugin, new Runnable() {
            int time = 5;
            @Override
            public void run() {
                if (time == 0) {
                    return;
                }
                for (Player p : getTraders().values()) {
                    p.playSound(p.getLocation(), Sound.ENTITY_TNT_PRIMED, 2, 2);
                }
            }
        }, 0L, 5L);

[summer scroll]

yes, use lambda by the way

[tardy delta]

never used it : )

[summer scroll]

Just replaced new Runnable() with () ->

[tardy delta]

i got an error now

[waxen plaza]

I think you need to remove run

[granite stirrup]

It's 69%

[tardy delta]

ah yea

never worked with it before so ugh

[granite stirrup]

If you use BukkitRunnable I think it would work

[ivory sleet]

You can’t declare it with both the anonymous class instantiation syntax and lambda body expression

[granite stirrup]

Wait is that saying every 0 ticks ??

Or is it 5 ticks ?

[tardy delta]

ah yes i think 🤔

[granite stirrup]

I think you should give your server some time to breathe lmao

Probs wouldn't want to do 0 ticks

[summer scroll]

It's every 5 ticks, the delay is 0

[tardy delta]

i want every second

so that would be 20 right?

[ivory sleet]

It will still be scheduled the next tick, mye 1 tick = 0.05 seconds

Best case

[waxen plaza]

Is the bukkit runnable better??

[ivory sleet]

Depends

[waxen plaza]

I have a scheduler to save data in my database every 20minutes

[granite stirrup]

You know I don't get why they can't just be a delay and that's how much ticks untill it runs

[ivory sleet]

Not like using the BukkitRunnable over BukkitScheduler or vice versa is a performance win. Only reason you would choose the one or the other is cause of lambdas being syntactically cleaner or the fact that BukkitRunnable is impure.

[summer scroll]

isn't that the delay function? wait x ticks before the scheduler runs for the first time.

[granite stirrup]

Idk

[ivory sleet]

The parameter names are really bad

First one is initial delay in ticks, second one is interval in ticks

[granite stirrup]

Lol

Is that mojangs fault?

Or spigot/bukkit

[ivory sleet]

Probably spigots

[rugged topaz]

derives from the bukkit class, so.

[ivory sleet]

Normal java scheduledexecutorservices actually have it that way (initialDelay and interval)

[granite stirrup]

Lol

Md_5 fix it

[rugged topaz]

if (p.getInventory().firstEmpty() == -1 || p.getInventory().addItem(item2) != null) {
    p.getLocation().getWorld().dropItem(p.getLocation(), item2);
}

is this how you check to see if addItem successfully added an item and that their inventory isn't full?

[summer scroll]

addItem is annotated @NotNull

[granite stirrup]

:/

[rugged topaz]

oh then

.isEmpty instead of null

but with a ! so

if (p.getInventory().firstEmpty() == -1 || !p.getInventory().addItem(item2).isEmpty) {
    p.getLocation().getWorld().dropItem(p.getLocation(), item2);
}

yea?

[granite stirrup]

What if it returned null with the @NotNull 🤔

[rugged topaz]

if it's annotated @notnull by the dev, it'll never return null.

[eternal oxide]

it can't

[rugged topaz]

isn't that how it is?

rather in my case, it returns an empty hashmap

but always returns a hashmap, empty, or filled

[granite stirrup]

Will it throw a error?

[ivory sleet]

Bad software

[eternal oxide]

It would not compile

[ivory sleet]

It certainly would

[granite stirrup]

Oh lol

[rugged topaz]

does no one know whether or not this's the solution?

[ivory sleet]

Annotations are just annotations

[eternal oxide]

I thought those annotations implemented compile checks?

[ivory sleet]

Hmm maybe certain ones like ides supporting checkerquals or something

[summer scroll]

lombok 🥶

[ivory sleet]

Mye lombok is annotation processing I think

Probably throws if you try anything impossible with it

[summer scroll]

You can try it

[eternal oxide]

Just did some reading and it does seem the annotions are blind

[rugged topaz]

okay

[eternal oxide]

It will give warnings at compile time.

[waxen plaza]

Is it possible to show like in the picture [<level>] without being a tab completion?

[eternal oxide]

no

completions are simple string lists

[rugged topaz]

crashing with OutOfMemoryError: GC Overhead Limit Exceeded is the result of a memory leak right?

[ivory sleet]

Yup

[rugged topaz]

okay and is there a way to like, see the memory values of a java program?

[ivory sleet]

Or u have some bad gc jvm flags

[rugged topaz]

ill send them

[ivory sleet]

Profiler

[eternal oxide]

my guess is an unending loop

[ivory sleet]

Yanlol

Why is ur min allocated ram set to ur max allocated ram

[rugged topaz]

is that an issue?

always used that

[rugged topaz]

it's actually paperspigot :)

[ivory sleet]

It’s immensely stupid, kinda defeats the point

[rugged topaz]

what's a recommended value?

like, 200MB less than the max

or

[ivory sleet]

Well how much ram do u have available

[rugged topaz]

well uh, 16gb on the system

running a bungeecord server, and 2 other paperspigot

[hybrid spoke]

why do you want to keep your ram that high if you don't need it

[ivory sleet]

1G, 3G maybe then

[rugged topaz]

theoretically, the higher the ram the easier it was to deal with the memory leak as it'd take longer to crash

immensely stupid of me but

i couldn't get to the bottom of it at all

[hybrid spoke]

with what memory leak?

[ivory sleet]

Also send the memory errors full stacktrace

[rugged topaz]

that's if i can get it, i made a plugin to auto restart the server to prevent data loss when memory is less than 700 off the max. so i'll have to check logs or whatnot

[calm whale]

Can anyone please take a look at my problem ?
https://www.spigotmc.org/threads/create-maven-repo-from-github-repo.514307/

[rugged topaz]

so setting the minimum flag isn't gonna be the answer to my solution?

[ivory sleet]

Probably not if it’s a memory leak you’re dealing with

But optimizing jvm flags isn’t a bad idea nonetheless

[hybrid spoke]

doesn't seem like a memory leak. more like that you are creating new instances of an object frequently

[rugged topaz]

instantiating an object isn't collected by the garbage collector inside a function?

[ivory sleet]

It is

[rugged topaz]

or do you mean i'm looping it

okay

[rugged topaz]

-Xms1G -Xmx3G?

[ivory sleet]

Sure

[rugged topaz]

well for some reason that caps it at a gig

[ivory sleet]

Yes because it has only allocated that 1G

[rugged topaz]

so what's the meaning of the xmx3G?

[ivory sleet]

Max allocation

[granite stirrup]

When is it gonna be the future where spigot uses like 1mb of ram on its own

Probs not possible

[ivory sleet]

Technically possible with a lot of sacrifice like not caching stuff etc

[eternal night]

maybe instead of abusing github repos as maven repositories, use github packages ? https://docs.github.com/en/actions/guides/publishing-java-packages-with-maven

[calm whale]

I didn't know that github offers it's own maven host

[tribal sparrow]

does anyone know if it's possible to spawn a beacon beam? can't see anything on the docs (https://hub.spigotmc.org/javadocs/spigot/org/bukkit/block/Beacon.html) and a google search comes up with mostly people saying its client side however those posts are years ago so maybe something could have changed?

[hybrid spoke]

it's clientside

[young knoll]

You might be able to do something with packets

I think wynncraft does it with the end gateway beam

[hybrid spoke]

should also be clientside iirc

[quiet ice]

Could evt.getEntity().getNearbyEntities(1, 1, 1) also include dead/removed entities?

[calm whale]

I don't think so

[young knoll]

Well they do it ¯_(ツ)_/¯

[hybrid spoke]

are you sure that its THAT beam? not the guardian one with a custom texuture? not particles?

[hybrid spoke]

nope

[quiet ice]

not even if the method is called in the same tick?

[hybrid spoke]

not if you remove it before

if you remove it after getting nearby entities, its not dead or removed yet

just afterwards

[young knoll]

Mhm

[quiet ice]

I am performing a #remove before and after (the method may be called multiple times). Yet, I am getting some form of exploit that could only be caused if the entity is still considered alive but was already killed by my plugin

[hybrid spoke]

could it be that they just set gateway-blocks?

[quiet ice]

wiki.vg does not mention anything of beacon beams - so protocol side they aren't anything special (if they exist)

[young knoll]

Could be

[hybrid spoke]

those beams are clientside, so it have to be

[hybrid spoke]

debug it

and what type of "exploit" is it?

[quiet ice]

can't - I cannot reproduce the issue so I have just to go by words

[wild marten]

is there a way to add a new update checker to my plugin

[opal juniper]

Sure there is

[weary geyser]

There is a tutorial on spigot

[hybrid spoke]

why shouldn't there be a way

[weary geyser]

For it

[opal juniper]

I think Choco has made one

[quiet ice]

XP being added far more than usual. The only code that would explain this would be

                    evt.getEntity().teleport(Grab.grabLocs.get(grabLoc));
                    evt.getEntity().setPickupDelay(0);
                    for (Entity e : evt.getEntity().getNearbyEntities(1, 1, 1)) {
                        if (e instanceof ExperienceOrb) {
                            // Grab.grabLocs is a Map<Location, Player> map 
                            Grab.grabLocs.get(grabLoc).giveExp(((ExperienceOrb) e).getExperience());
                            e.remove();
                        }
                    }

[weary geyser]

[umbral pagoda]

hi all ihave proplem with my skypvp plugin when i hit any one with bow it give me error in consol and when i hit with rod the same error
