[slender elbow]

sure

[grim hound]

but still, how does it work?

[dawn flower]

hold up

[next plume]

April 22-26

[slender elbow]

it generates a class that implements the interfaces

[dawn flower]

does /transfer require bungeecord

[remote swallow]

no

[slender elbow]

and the method calls will call your IH

that's all

there is no magic

[remote swallow]

it just requires the packet to be accepted by the other server

[slender elbow]

if you want to delegate those calls to another object sure you can do that

[dawn flower]

so minehut wont be able to mask ur ip no more

[remote swallow]

bungeecord will still work

minehut can do whatever they like

[grim hound]

what if it ain't an interface?

[slender elbow]

then you can't use Proxy

[grim hound]

but rather just a class

[remote swallow]

if md decides to make bungee work of transfer packets he can do that, if he doesnt he doesnt

[grim hound]

then what do I do?

[remote swallow]

if minehut dont/do they can do that

[slender elbow]

then don't use Proxy?

extend the class or something

[grim hound]

can't

nms shit

[slender elbow]

Proxy is more for dynamically generating an impl of an interface, e.g. you don't know what the interfaces are

surely you can extend a class

unless it's final

gg

[grim hound]

it ain't final

but

stuff like this

and I won't do it for each version separately

[remote swallow]

so get it from the craftbukkit package

or if you wanna support future back Bukkit.getVersion

[slender elbow]

I mean then you go ahead and spin up your own bytecode gen

using asm or something

to extend the class and do w/e you want

like if it was source code, but without the source code

[grim hound]

I'm decently sure libraries exist for that

[slender elbow]

yes it's called asm

or bytebuddy

which uses asm

or you can have a java source code template

that you then compile at runtime

the world is your oyster

[dawn flower]

what in the world is a bogged

this doesnt look minecrafty

[worldly ingot]

It has to look Minecrafty

It's in Minecraft

[astral pilot]

how?

[dawn flower]

well not yet

[astral pilot]

also I don't think so since that other plugin is also made by me

[dawn flower]

that looks like something straight from hytale or minecraft dungeons / legends

[worldly ingot]

Well now it's in Minecraft so it looks like it's straight from Minecraft

I don't know what you want us to tell you lol

[lost matrix]

Then you might just overwrite it by yourself using the same keys

[dawn flower]

anyways can u store a map in a pdc

[remote swallow]

looks like a mossy skeleton

[remote swallow]

sure

[dawn flower]

how

[remote swallow]

serialize to byte array

[dawn flower]

what if my thingi isnt serializable

[worldly ingot]

Or you can use the data container itself

PersistentDataType.TAG_CONTAINER is just a map

[dawn flower]

it's an enchants plugin and idk if storing a tag for each enchant is efficient

[dawn flower]

aight thanks

[neon shoal]

Usefully likes for plugin Dev?

[blazing ocean]

?morepdc IIRC

[undone axle]

You can create custom persistent data types on your own, or use one of the many libraries available which have implemented those which match your needs. Learn about more persistent data types here: https://www.spigotmc.org/threads/more-persistent-data-types-collections-maps-and-arrays-for-pdc.520677/

[worldly ingot]

How do you think vanilla stores enchantments? :p

[neon shoal]

Links

[dawn flower]

in a map in pdc

[worldly ingot]

Enchantments: [{id:"", level:0}, {id:"", level:0}, {id:"", level:0}]

It's a list of objects

[dawn flower]

map ^

o h

[worldly ingot]

In which case you're looking for PersistentDataType.TAG_CONTAINER_ARRAY

[dawn flower]

and just store my custom enchant object?

[worldly ingot]

Well you'd have to serialize it to a PersistentDataContainer, but yeah

[remote swallow]

Can i make a list of a tag container array

[dawn flower]

all primitives are serializable right?

[worldly ingot]

Yes

[dawn flower]

aight

[worldly ingot]

Primitives, strings, and arrays of some primitives

[river oracle]

Why would you

That's an abuse of the system

But in short no absolutely not a arrays are meant to be replaced by lists

[astral pilot]

isn't this impossible because using the same key will make the plugin throw an error

[dawn flower]

wait what happens if i create an array of an array

eyo it works

[worldly ingot]

There's no type for arrays of arrays, but no reason it wouldn't work if you added one yourself

[dawn flower]

String[][][][][][][][][][][][][][][][][][] strings; this works fine

[worldly ingot]

Oh, yeah, that's fine

[dawn flower]

why would anyone need this

[worldly ingot]

You're discovering the existence of multi-dimensional arrays :p

They're usually only useful up to like 3 dimensions, and even then you probably just want a better collection for that

[river oracle]

CabernetMC does everything into the 4th dimension because of our extremely complex nature but for the normies going past 3d arrays is unneeded

[blazing ocean]

i don't remember ever using an actual array in java/kotlin

[dawn flower]

why doesnt spigot add a world particles event, kinda annoying to use protocollib for such a simple thing

[blazing ocean]

always lists

[river oracle]

?contribute

[undone axle]

https://hub.spigotmc.org/stash/projects/SPIGOT/repos/craftbukkit/browse/CONTRIBUTING.md

[river oracle]

They're very useful if you know you have a specific amount of things

Which tbh isn't mant use cases you'd see at this level :P

[icy beacon]

I guess what arrays have got is speed

[dawn flower]

and static lists

u wouldnt need to create a whole list for something like "apple" and "orange"

[glad prawn]

List<? extends Fruit> xd

[astral pilot]

anyone?

[lost matrix]

No. It doesnt unless two plugins register a recipe for exactly the same key.

[icy beacon]

What about identical recipes

[dawn flower]

which isn't possible

something keys require a plugin instance

[astral pilot]

hows that even possible since registering 2 recipes with the exact same key makes the plugin throw an error

[icy beacon]

Identical ingredients, different results

What if that happens

[dawn flower]

Fruit[] array = {Fruit.APPLE, Fruit.ORANGE}

List<Fruit> list = new ArrayList<>();
list.add(Fruit.APPLE)
list.add(Fruit.ORANGE)```

idk abt u but the array seems way more efficient

[icy beacon]

You can create a NamespacedKey without a plugin instance using fromString. Or get a plugin instance from PluginManager

[dawn flower]

why in the world would u do that

[lost matrix]

List<Fruit> list = List.of(Fruit.APPLE, Fruit.ORANGE);

[icy beacon]

Why not

[icy beacon]

Any idea?

[dawn flower]

:-:

[icy beacon]

I'm curious now

[dawn flower]

array initialization takes less chars than list initialization

[lost matrix]

Show your code and how you determined that recipes are conflicting. The probability of a user error is very high.

?paste

[undone axle]

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

[dawn flower]

who's md5

(hopefully he isn't here or im screwed)

[glad prawn]

[dawn flower]

ik their skin

is he a contributor, owner, discord owner, discord staff, staff or what exactly

[remote swallow]

no

i want a PersistentDataType.LIST.TAG_CONTAINER_ARRAY

[river oracle]

no

does not exist

[remote swallow]

i would like it

pls add

[dawn flower]

PersistentDataType.LIST.LIST.TAG_CONTAINER_ARRAY

list of a list of a tag container array

[worldly ingot]

Wouldn't you be able to do PersistentDataType.LIST.listTypeFrom(PersistentDataType.TAG_CONTAINER_ARRAY)?

[astral pilot]

Plugin1
https://paste.md-5.net/gofekefami.cs

Plugin2 (The one which the recipe disappears when Plugin1 is running along with it)
https://paste.md-5.net/ofukecuser.cpp

[dawn flower]

how are you expecting to have 2 exact recipes and both work

[remote swallow]

idk

@eternal night can i do that

[dawn flower]

i believe there's a priority system or something for recipes

[remote swallow]

@river oracle what this

[lost matrix]

Nope, the first registered recipe is the one thats being used

[dawn flower]

why..

just make plugin1 loadBefore plugin2

the opposite*

plugin2 loadBefore plugin1

[astral pilot]

no its not 2 exact recipes

[lost matrix]

Check with /pl if both plugins are properly enabled

[astral pilot]

its 2 distinct recipes

[river oracle]

you finding out I'm lying because I'm trying to stop you from doing something stupid 😭

[remote swallow]

oh i dont plan to do anything

i just want a list array

[dawn flower]

List<String[]>

[remote swallow]

i want like 9 d array

[blazing ocean]

why

[remote swallow]

fun

[dawn flower]

String[][][][][][][][][]

[astral pilot]

i did, they're both enabled

[eternal oxide]

errors in startup log?

[zealous osprey]

._.

[astral pilot]

nope no errors

[dawn flower]

r ucalling the methods

[astral pilot]

wdym by this

[dawn flower]

the methods to register them

craftingInitializer

setCrafting

[astral pilot]

yea im calling those

whenever i remove Plugin1

plugin2's recipe works

[vast ledge]

How can i prevent the Swapping of an Item with hotkeys in a Player Inventory, Currently im checking both the cursor and current item if its an custom item, this stops the item being moved around normally, but doesnt prevent hotkeying.

[dawn flower]

it should work for hotkeying

try InventoryInteractEvent

[vast ledge]

That event doesnt provide any Itemstacks tho, how would i go about detecting it there?

[astral pilot]

does spigot have debug console or something?

[vast ledge]

wdym debug console?

[astral pilot]

something like verbose

[remote swallow]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/player/PlayerSwapHandItemsEvent.html

[lost matrix]

Do you tinker with the ItemCraftPrepareEvent?

[vast ledge]

I needed that to, but i mean if i m hovering over slot 6, and then press 1, the item from slot one moves to 6, how would i prevent this?

[remote swallow]

listen to inv click and inv drag and print whats gets ran

[vast ledge]

The Inventory drag event doesnt get fired tho afaik

[astral pilot]

ohhhhh

ok i see where the error comes in

[vast ledge]

Yea the Inventory Drag event isn't getting fired

[astral pilot]

public class PlayerCraftingEvent implements Listener {
    @EventHandler
    public void onPlayerCraft(PrepareItemCraftEvent e) {
        CraftingInventory inv = e.getInventory();
        ItemStack result = inv.getResult();

        // Now this code may conflict with other plugin
        if (!getCraftingResults().contains(result)) {
            inv.setResult(null);
        }
    }
}

yea i guess this is what causes it

thanks for the help

[lost matrix]

[polar forge]

Hey guys

[vast ledge]

Hello Egitto

You were the one with the hoverable messages right?

[polar forge]

Yea

[vast ledge]

What do you need today?

[polar forge]

I got helped yesterday, but it doesn’t work yet

So I changed some stuff

I now when I load the hoverable message plugin, I can’t see my prefixes from LuckPerms

[high arrow]

Hello, I have the following problem: I can't join my server because of this error:

I tried removing one plugin, and it solved the issue. The problem is that I haven't really changed something in it, it came itself, I don't really do much in the join event except giving items...

[vast ledge]

The normal ones in chat or?

[vast ledge]

Packet to large

[polar forge]

Yea, permissions work, but prefixes don’t

[high arrow]

ik, but which one ?

[vast ledge]

32

[polar forge]

So I implemented the dependencies of LuckPerms, I did some coding

But it still doesn’t show the prefixes

Should I send the code?

[vast ledge]

Sure

?paste

[undone axle]

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

[high arrow]

there's no sign tho

[vast ledge]

You sure none of your plugins has custom signs or the sorts?

[high arrow]

none

but i have this part of code that do stuff about location

[polar forge]

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

[vast ledge]

Teleporting into unloaded chunks and then sending an oversized packet?

But that shouldnt happen

[vast ledge]

sec i brb

[polar forge]

Sure take ur time

[granite owl]

is there a way to take a bunch of primitives and serialize them as byte array like in C?

[worldly ingot]

Packet 32 is not packet 0x32

It's packet 0x20. And what 0x20 is will depend on your client version

[granite owl]

or better say, should it not be done?

[eternal oxide]

You are using teh player name not display name TextComponent comp = new TextComponent("" + player.getName() + ": ");

[vast ledge]

Why is it x20 and not x32?

[worldly ingot]

Packet 32 is the decimal value (base 10). In hex, 32 is 0x20

[vast ledge]

ah

Thanks

[high arrow]

the 0x20 for wiki.vg is that

[worldly ingot]

Again, will depend on your client/server version

[vast ledge]

Depends on the version :D

[high arrow]

ah

[vast ledge]

So what exactly isnt working?

[polar forge]

LuckPerms Prefixes

[eternal oxide]

I already gave him his answer

[vast ledge]

Oh

[vast ledge]

@polar forge

[eternal oxide]

he's using player name not display name in his text

[polar forge]

Oh thanks

Ill try it out and see if it works

[vast ledge]

Thank Elgar, he found it!

[vast ledge]

Anybody got an Idea?

I take the dead silence as a no...

[high arrow]

it's the same with a newer version tho

[golden turret]

?? why is this happening?

[eternal oxide]

check the ClickType

[vast ledge]

I know when its a hotkey, but what do i do differently when its a hotkey?

[polar forge]

So it should be: TextComponent comp = new TextComponent("" + player.getDisplayName() + ": ");

[vast ledge]

Yea

[polar forge]

Oh ok

[eternal oxide]

if the slot you want to protect is clicked then cancel

[vast ledge]

If feel so stupid not thinking of that

[polar forge]

Silly

[vast ledge]

Wtf

Why is slot 2, 37???

Oh

its a raw slot

Makes sense

[eternal oxide]

This is what I did to test locking a slot```java
@EventHandler
public void onClick(InventoryClickEvent event) {

    if ((event.getSlot() == slotToLock && event.getSlotType() == SlotType.QUICKBAR)
            || (event.getHotbarButton() != -1 && event.getHotbarButton() + slotToLock == slotToLock))
        event.setCancelled(true);
}
@EventHandler
public void onSwap(PlayerSwapHandItemsEvent event) {

    if (event.getPlayer().getInventory().getHeldItemSlot() == slotToLock)
        event.setCancelled(true);
}```

you'd also have to check in teh drop event

[polar forge]

This is pretty strange, even if I’m not op, I always have this colored name

And that prefix

[eternal oxide]

you only modify the name in the join event

anything you do after will not alter teh prefix

[polar forge]

Why do I see the &c then?

[valid burrow]

its not &

you need to use paragraph

not and

[eternal oxide]

you see &c because you didn;t translate color codes

[valid burrow]

…

then translate color codes?

[polar forge]

What do u mean?

[valid burrow]

either u start using § or u translate color codes xd

[polar forge]

They are already translated in the code

[eternal oxide]

ChatColor.TranslateAlternatColorCodces("&", message) or something

[valid burrow]

i honestly dont know what you are askin rn

player names are modified onPlayerJoinEvent in your code

[eternal oxide]

you don;t translate color in any code you have shown

[polar forge]

1. Why do I see &c
2. Why do I still have the red name and &c if I’m not op and I’m in the default group

[inner mulch]

Is toggle shift called when in an inventory?

[eternal oxide]

what prefix are you getting from LP?

[polar forge]

My prefix is &c

[eternal oxide]

then

[polar forge]

To make my name red

[eternal oxide]

translate it

[polar forge]

But why is my name red if I’m not op?

Ill translate it now

[valid burrow]

Cause its set onjoin

for gods sake

[eternal oxide]

because you have the hoverinfo.admin permission I guess

[valid burrow]

it only updates when you join

cause thats how your code works

changing the permissions doesnt trigger a playerjoinevent

[polar forge]

What’s the solution then?

[valid burrow]

„the solution“ doesnt exist

[eternal oxide]

you have to work out the display when they chat

not when they join

[valid burrow]

theres a million ways to habdle this

[valid burrow]

you wanna change the username on every chat message?

what

is the displayname

[eternal oxide]

there might be minutes between chats, so anything can happen

also permission expiry can affect it

and changing worlds

so he needs to check each time the player chats

its not a heavy query

[polar forge]

Ok I rejoined and I indeed see my name white

But I see null next to my name

[eternal oxide]

Just create a methodjava public String getFormattedName(Player player) {

then do in there what you currently do in in teh PlayerJoinEvent

except don;t set the display name, just return a string

[polar forge]

I think I’ll just keep it on join event

[valid burrow]

but thats a stupid solution

[remote swallow]

no it isnt

[valid burrow]

yes it is

imagine you change someones rank

[eternal oxide]

Far from it

[remote swallow]

thats exactly how almost every single chat plugin works

[valid burrow]

and they need to send a chaz message for it to apply

OMG YALL

[remote swallow]

voss

[valid burrow]

PLS READ

[remote swallow]

use ur brain

[valid burrow]

DISPLAY NAME

DISPLAY NAME

[remote swallow]

you DONT modify display name

[valid burrow]

DISPLAY NAME

DISPLAY NAME

[remote swallow]

DONT MODIFY IT

[polar forge]

Don’t spam

Smh

[valid burrow]

BUT THATS WHAT HIS CODE DOES

[remote swallow]

good for him

we've given the solution to fix

[eternal oxide]

and I'm telling him NOT to do that

[valid burrow]

youre telling him to update it on every chat message

[eternal oxide]

I literally just told him to create a method to return a formatted String

[remote swallow]

no

read this again for me

[valid burrow]

yh he said that after i send my messages

smh

[remote swallow]

no he didnt

he sent it before

[valid burrow]

?

[remote swallow]

restart ur discord

elgarl was first

[valid burrow]

im on phone

[remote swallow]

close discord, close the app

[remote swallow]

and then open it agaim

[polar forge]

I also see what Siea sees

So

[remote swallow]

i just reloaded my discord

elgarl was first

[valid burrow]

kk

[eternal oxide]

I win, you suck 😛

[polar forge]

But guys no need to have beef with each other

[blazing ocean]

nuh uh

[eternal oxide]

We just playing 🙂

[blazing ocean]

this is spigotcord

[polar forge]

But guys, I think I’ll just keep it on join event

So 1 problem is actually resolved

[valid burrow]

yh we love each other

[eternal oxide]

it will nto work in join

[polar forge]

But I have now the problem with the null and &c

[eternal oxide]

yes you do

[polar forge]

So u guys told me to translate it right?

[eternal oxide]

yes

all &code have to be translated

[polar forge]

I never coded for a translate so it’s my first time

[eternal oxide]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/ChatColor.html#translateAlternateColorCodes(char,java.lang.String)

("&", stringYouNeedToParse);

[polar forge]

I hate when sites don’t show an example

[valid burrow]

thats how documentation works

[polar forge]

Could I just use

[unborn breach]

Hey my server got griefed is ther a way to rollback my server for 3 hours

[polar forge]

prefix.replace(‘&’, ‘§’)

[polar forge]

Do u have coreprotect?

[eternal oxide]

don't

[unborn breach]

i do but i also need inventory's rollbacked

[eternal oxide]

you could do that, but don't. Use the provided method

[polar forge]

Inventories wont work

[polar forge]

Ok I will

[unborn breach]

cant i rollback the server for 3hours by changing a file?

[polar forge]

Do

[eternal oxide]

if you have backups, yes

[polar forge]

/co rollback time:2h radius:30000

[unborn breach]

but that wont change inventory's

[polar forge]

No

[unborn breach]

where can i see my backups?

[remote swallow]

what makes your backups

[unborn breach]

cuz i didnt make the big back up thing.
but i think i got something called auto backup so i just have to rename a file i just dont know where to find the file

[remote swallow]

is it a plugin

[unborn breach]

no

i mean i got coreprotect but i also need inventory's

[polar forge]

Like this?

[eternal oxide]

prefix = ChatColor.Translate...

as Strings are not Mutable

[polar forge]

ChatColor.Translate doesn’t exist

[eternal oxide]

... means theres more

use the method you are but put prefix = before it

[polar forge]

Ok

[eternal oxide]

the methods returns a modified String as Strings are immutable (can not be edited)

[quaint mantle]

Crazy

[polar forge]

But I already have a prefix = is it ok if I make another one?

[eternal oxide]

you are not making another

just reassigning it

[polar forge]

But I still can’t find what comes after the dot

ChatColor.

[eternal oxide]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/ChatColor.html#translateAlternateColorCodes(char,java.lang.String)

[dawn flower]

when trying to use TAG_CONTAINER

[eternal night]

int

[polar forge]

Like this?

I know it’s wrong

But in that file it doesn’t explain what u told me to do

[dawn flower]

do i need to input map or what

[eternal night]

no, you input a PersistentDataContainer

[dawn flower]

how do i create one

[upper hazel]

how i can set for living entity path to location

[polar forge]

No wait

It’s actually

prefix = ChatColor.translateAlternateColorCodes( altColorChar: '&', prefix);

Is that right Elgar?

[eternal night]

you can get the context of a PDC and ask it to create one for you

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/persistence/PersistentDataContainer.html#getAdapterContext()

[polar forge]

But is it correct?

[cinder abyss]

you should learn java to know that

[polar forge]

Ok then it’s correct

But how do u translate null?

I now translated every code that started with &

[rapid vigil]

I've told you countless times yesterday to take a java fundamentals course and come back to spigot. Even if you were spoonfed this entire project (as it is right now) you will not be able to create more projects freely later on, you'll have to depend on others to spoonfeed you code while you don't know what you're doing

[polar forge]

I understand what I code

[cinder abyss]

...

[polar forge]

That’s what I receive in my console

[cinder abyss]

you don't know java.

null represent something that don't exist

you can't manipulate it

[rapid vigil]

Yeah yeah, that's quite obvious 😅

[cinder abyss]

so

[cinder abyss]

PLEASE.

[tardy delta]

bruh

[polar forge]

Then why does it show as a prefix?

If it’s nothing?

Explain

[cinder abyss]

because you translate null to "null"

basically

so it's working, but you can't use it to translate a color

[polar forge]

Then why does it show?

I never used null in my code

Should I send the code

(message deleted, because my stupid ass couldnt differenciate the files "buildData" and "buildModeData" )

[solar pier]

Is possible to disable or modify minecraft recipe book?

[silent slate]

the crafting is client side, you could use a resource pack to hide the crafting/recipe book icons, still it could be accidentally clicked on and used.

Use a mod if u want to disable it, or get a plugin that cancels the event when a player puts an item in the crafting menu

[worthy yarrow]

Anyone know of a solid lockable chests plugin?

[rapid vigil]

make one 😜

[remote swallow]

lockette pro

[worthy yarrow]

True, but why do that when one already exists

[worthy yarrow]

How difficult to update that to 1.20+ compatibility? If you know

[remote swallow]

does it not work?

[tranquil beacon]

when I used to run a server (a few years back), I used LWC (I think that's what it was called?) and it was pretty good, although I'm not sure if it still gets updates

[worthy yarrow]

It just says 1.14-1.19, wasn't sure if that might cause issues with a 1.20+ server

[remote swallow]

try it

im guessing it will work

[worthy yarrow]

Me too, just in case

[worthy yarrow]

We'll have to check on that if lockette doesn't work

Hmm

[tranquil beacon]

sure, I just checked out of curiosity, and it looks like someone else has taken it over. It still receives updates, with the latest one being in february, and it's available for versions 1.8 to 1.20
https://www.spigotmc.org/resources/lwc-extended.69551/

[worthy yarrow]

Lockette is kinda goofy

[worthy yarrow]

Def like this more than lockette, seems lockette has become quite outdated

Thank you both either way, @remote swallow ,xellon

[junior cradle]

How to make an inter-server auction, can you explain the principle of operation, what should it be with the help of the data?

[wet breach]

how so?

and in what way is it outdated?

[worthy yarrow]

I figured out how to break it within the first 30 seconds of loading it up lol

[high arrow]

pls

[wet breach]

what broke with it?

[worthy yarrow]

When I placed a sign on the chest, entered the editor of the sign then exited and it switched from [private] -> [error]

[wet breach]

are signs re-editable now?

[worthy yarrow]

It said something about adding people to the chest, “right click the sign and then type /(I forgot the command) but it just enters the sign editor

[wet breach]

only two things come to mind, either you didn't setup configs properly or you gave yourself all perms

[pseudo hazel]

yeah pretty sure 1.20 added editable signs

[worthy yarrow]

Well I put it into a local host, cuz I’m not sure any conflicts with the server that needs it

And I least need to figure how to use it to test it, but then I broke it haha

[wet breach]

quite possible then if lockette hasn't been updated that this will indeed break it since it isn't designed to handle this

I am quite familiar with lockettes code, well up to a point anyways 🙂

[peak depot]

BungeeCord related question: java player.connect(info, ServerConnectEvent.Reason.COMMAND); what does the Reason do

[worthy yarrow]

Lockette is 1.14-1.19 on the spigot page, didn’t check the last update

[wet breach]

well lockette strictly uses API only methods

hence why it has worked for as long as it has without much needing to be done with it lol

also because it uses signs, no DB is needed either unlike LWC for example

but, the editable signs thing should be actually easy to incorprorate into lockette though

[worthy yarrow]

Right yeah, well lwc has more quality of life so I’m just gonna stick with that or perhaps just fix lockette if lwc has conflicts

[wet breach]

not hard to fix lockette

really its just adding an additional listener

cancelling if the sign doesn't belong to the person trying to edit

[worthy yarrow]

Yeah not saying the fix would be hard, rather just if lwc works then there’s no need as lwc is updated + maintained as well as quality of life features

[wet breach]

if quality of life features are something you need sure

[worthy yarrow]

Idk I gave the server owner both of the options so it’s up to them at this point

I’d assume they’d rather quality of life, it’s a survival server and they’ve got some semi large teams

Still, Lockette works perfectly for this, lwc just has the qol benefits

[wet breach]

if you think so

[dawn flower]

what's a good formula to get the middle of lore of an item to put custom enchants lore

[dawn flower]

high quality english

[tardy delta]

would reserve capacity

also why is everything object

and cant you reuse the context?

[lilac dagger]

i'm working with Field class

i could reserve capacity yeah

but it's just a one time serialization

and the context can change look

[tardy delta]

can i see inferCollection?

[polar forge]

Guys any solutions for this problem?

[polar forge]

Im basically implementing LuckPerms prefix to my Hoverplugin

[remote swallow]

dont modify the display name and only change what they see on player chat event

[lilac dagger]

^

[polar forge]

Could u tell me where in this code I should change the player chat event? Which line? https://paste.md-5.net/xonuguzipu.java

[tardy delta]

whats getClassFromType?, im sorry im thinking about intrinsical optimizations

[remote swallow]

remove this

[lilac dagger]

it's just a type converter

[remote swallow]

and in async chat event called event.setFormat

[lilac dagger]

there's nothing fancy in there

[tardy delta]

Field::getGenericParameters a thing?

[lilac dagger]

ah no

[tardy delta]

also whats a generic param on a field even supposed to mean

[lilac dagger]

it's Object<Type>

the generic is the Type

[remote swallow]

i love type erasure

[lilac dagger]

i can do this which is nice

[polar forge]

This whole code?

[remote swallow]

dont modify the display name, so remove that listener

i get around my generics with https://github.com/PineappleDevelopmentGroup/Pineapple/blob/dev/pineapple-core/src/main/java/sh/miles/pineapple/config/ConfigType.java

[tardy delta]

you can ask the jvm for the rtti

[lilac dagger]

you could simplify it

https://github.com/google/gson/blob/main/gson/src/main/java/com/google/gson/internal/%24Gson%24Types.java

[remote swallow]

what if i have Map<List<String>>

[lilac dagger]

this class is the nicest

[remote swallow]

what then

[lilac dagger]

it's not supported by yaml

actually nvm it is

it works

[remote swallow]

mine supports that

[lilac dagger]

one sec

[polar forge]

So like this?

[rapid vigil]

LMAO

[lilac dagger]

it supports it

[orchid trout]

dude

[polar forge]

They told me to remove my listener

But keep the display name

[lilac dagger]

this is also why i clone the type context ^

[tardy delta]

i hope you know what youre doing

[lilac dagger]

i mean the code works, it took me some time to optimize

it's pretty safe

i hope i did a good job with it

[polar forge]

`public void setPlayerDisplayName(Player player) {
User user = plugin.getLuckPerms().getUserManager().getUser(player.getUniqueId());
String prefix = "";
if (user != null) {
prefix = user.getCachedData().getMetaData().getPrefix();
}

if (player.hasPermission("hoverinfo.admin")) {
    player.setDisplayName(prefix + ChatColor.RED + player.getName());
} else if (player.hasPermission("hoverinfo.moderator")) {
    player.setDisplayName(prefix + ChatColor.AQUA + player.getName());
} else if (player.hasPermission("hoverinfo.default")) {
    player.setDisplayName(prefix + ChatColor.WHITE + player.getName());

} else if (player.hasPermission("hoverinfo.stone-mod")) {
    player.setDisplayName(prefix + ChatColor.WHITE + player.getName());
}
player.setPlayerListName(prefix + player.getName());

}
`

Like this?

[tardy delta]

sounds like a list of pairs but java doesnt have first class support for pairs smh

[sullen canyon]

is it an open source project?

[lilac dagger]

nope

it's part of my game engine

[civic sluice]

Just use a record.

[tardy delta]

would probably put all those types in one file if they're short

i forgot records were a thing

records have ~overhead~ tho if you wanna be very pessimestic

how you even write that word

[rough drift]

@polar forge

private final Map<String, ChatColor> permissionColors = new LinkedHashMap();

// Fill the colors from highest perm to lowest perm

public void setPlayerDisplayName(Player player) {
    User user = plugin.getLuckPerms().getUserManager().getUser(player.getUniqueId());
    String prefix = "";
    if (user != null) {
        prefix = user.getCachedData().getMetaData().getPrefix();
    }

    for(var entry : permissionColors.entrySet()) {
      if(player.hasPermission(entry.getKey())) {
        player.setDisplayName(prefix + entry.getValue() + player.getName());
        break;
      }
    }
}
```fyi you can do it like this

[tardy delta]

no point to a map if youre only iterating it

iterating entryset is even slower than iterating a list

[rough drift]

You can use a LinkedList

[polar forge]

Where u put the // should I paste my whole else if statement?

[rough drift]

no

just telling you that you need to do that

but use a LinkedList with a record or something

[polar forge]

I don’t understand

Was this an example?

[hybrid quartz]

How can I prevent player from putting items into gui? I have tried many ways, but all don't work

public class GUIEvents implements Listener {

    @EventHandler
    public void onClick(InventoryClickEvent e) {
        if (e.getClickedInventory() != null) {
            Menu menu = Menu.getMenuBy(e.getClickedInventory());

            if (menu != null) {
                Button button = menu.getButtonBy(e.getSlot());

                if (button != null) {
                    button.onClick();
                    e.setCancelled(true);
                }
            }
        }
    }

[rough drift]

yes

[rapid vigil]

Don't bother. He knows absolutely nothing about java, even after our countless attempts to get him to learn java basics

[orchid trout]

Event#setCancelled()

[polar forge]

I just need this small help

For this

[rough drift]

@polar forge are you perchance Italian

[polar forge]

Yep

[rough drift]

Oh okay that can make it easier to explain in DMs if you want?

you may be more comfortable in Italian ig

[polar forge]

Sure

Certo

[hybrid quartz]

I understand, but don't understand how to check if player is dragging something into gui.

[orchid trout]

Event#setCancelled()

also if you want to make guis https://www.spigotmc.org/threads/a-modern-approach-to-inventory-guis.594005/

[orchid trout]

youre only cancelling the event if its a button

[peak depot]

what do you guys think makes more sense I have a list with commands and I want to check if a message starts with /<command> should I loop through the list and check if String#startWith or should I split the message and check the first segment and do List#contains

[tardy delta]

why do you have a list of commands in the first place, why not a map

like subcommand -> instance

[young knoll]

Yay maps

[tardy delta]

did i summon you?

oh almighty

[peak depot]

I want to have a bungee system that always says "This command is not registred / you have no perms" no matter if you perms to execute or not but I want to have a whitelist that bypasses this and thats why the list

[tardy delta]

how does that bring you to the list?

[peak depot]

I need to decide on either one of those for allow/disallowing a command

[young knoll]

I would use a set

And then contains with the split

[tardy delta]

looks like whitelist checking or smth, idk im not really following atm

[peak depot]

look you do /plugins (I dont want that) so I dont add it to the whitelist and then the player gets a message "This command is invalid or you dont have perms"

and it doesnt get excecuted

[young knoll]

On spigot commands will be hidden if they don’t have the perms

Idk if bungee works the same

[peak depot]

nah you can still tab them also there are basic commands you have perms for and still I dont want the users to use them

[young knoll]

Rip

Bungee isn’t as cool as spigot

[peak depot]

you know if I can get the player from a connection

[sullen marlin]

Nah I think it is the same, probably just didn't set permissions

[quaint mantle]

[vernal cobalt]

you need to use lang level 8

pretty sure.

[remote swallow]

your compiling with 21, you need to run with 21

[vernal cobalt]

or that

[lilac dagger]

I think with maven you can use java 21 source and compile to java 8

[quaint mantle]

how I do that whit intellij

[quaint mantle]

I'm using gradle

[lilac dagger]

I think it's similar on gradle

[quaint mantle]

Now I compiled it with java 21 but still having the same problem

sourceCompatibility = 21
targetCompatibility = 21

[remote swallow]

your running with a lower java version

your running on 18 i think

[quaint mantle]

I'm trying to fix that, but no idea xd

[quiet ice]

Does anyone know whether java.lang.ref.Cleaner is thread-safe?

I don't really want to start up a bazillion demon threads just to clean up some resources in the background (these resources being soft references)

[tardy delta]

cant iirc

[quaint mantle]

when doing java -version appears 1.8

[tardy delta]

when did record appear?

java 14 or smth?

[quiet ice]

Why that?

I am pretty sure you can.

[tardy delta]

wait my thought process was that, if records were introduced in java 14 and you compiled to 8 that it wouldnt have the right ObjectMethods bootstrap methods, but thats just a descriptor, nvm

every time i wanted to compile to lower version, it didnt allow me to

[civic sluice]

Just compile with Java 21 and run with Java 21. In 1.20.5 you need anyways.

[tardy delta]

Each cleaner operates independently, managing the pending cleaning actions and handling threading and termination when the cleaner is no longer in use.
would assume so?

[quiet ice]

The question more lies in whether multiple threads would be able to register cleaners simultaneously

[tardy delta]

havent used that api but what method are you referring to?

[quaint mantle]

I changed the JAVA_HOME and path to 21 but still appears java 1.8 kek

[quiet ice]

https://docs.oracle.com/en/java/javase/17/docs/api/java.base/java/lang/ref/Cleaner.html#register(java.lang.Object,java.lang.Runnable)

Try to compile it from the CLI?

[tardy delta]

i mean

[quiet ice]

Doesn't forbid one from having logic in the constructor of that class.

[sullen marlin]

It just won't let you use any featured above java 8

[tardy delta]

thought so

[quiet ice]

I'll guess it isn't thread safe, as I'd doubt that the reference queue is thread-safe, but idk

[tardy delta]

CleanerImpl::getCleanerImpl assumes a static cleanerImplAccess has been set

[sullen marlin]

I'm confused what you're doing

[tardy delta]

anyways

[sullen marlin]

I don't think you need a cleaner or anything for this

[native gale]

How do I run some code after all plugins are done loading?

[remote swallow]

run it in a scheduler

schedulers dont start till after startup

[sullen marlin]

There's an initialise/load event, or just scheduler

[young knoll]

There’s also the ServerLoadEvent

Iirc

[sullen marlin]

Scheduler supports more versions

[quaint mantle]

This is getting so rare

java.lang.NoClassDefFoundError: java/net/http/HttpClient

[sullen marlin]

But also

?xy

[undone axle]

https://xyproblem.info/

[tardy delta]

alr goodnight

[quiet ice]

Well it isn't really spigot-related but for a webserver and I have a few open files being stored as SoftReferences (It's not bad to have them open 24/7 per-se, but after some long-term inactivity it'd be nice to just close them - and I can't be bothered to write actual caching for this - so SoftReference it is)

[native gale]

Eh, okay, I'll just describe my problem. Currently my plugin sends a notification to players whenever the server starts, so I put it into onEnabled. But there are some quick guys who are able to react to that notification and join before the last plugin manages to enable itself causing some plugins to behave weird afterwards. So I want the notification to be sent after all plugins are done enabling

[tardy delta]

destructor moment 🥺

[rotund ravine]

Iirc there is an event in newer versions

Otherwise just schedule a task, the first task will run only after a full init

[native gale]

Okay, good to know, thank you

[rotund ravine]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/event/server/ServerLoadEvent.html

[native gale]

I'll probably stick with scheduler, it sonds like a more flexible approach

[rotund ravine]

Oh he already said it haha

[ionic thicket]

is there a way to check if an entity is in water?

[young knoll]

[young knoll]

Javadocs? What are those

[remote swallow]

can a non living entity be in water

[worldly ingot]

Yeah. Why not? :p

Actually any entity can just be in water

[quaint mantle]

how to compile spigot 1.8 with java 21? I can't find a good solution

[sullen marlin]

doubt you can

[civic sluice]

I would assume that Java 11 is the max without hassle.

[sullen marlin]

When was 1.8 released

And when was java 21 released

You do the math

[civic sluice]

mc 1.8 was release around 2014 in the same year Java 8 got released. 😄

[nova notch]

goddamn 1.8 was nearly a decade ago

[quaint mantle]

so max java version for 1.8 is 11?

this shit aint working

[indigo axle]

I am trying to make a plugin that creates a light trail behind the player. Currently I have it place light blocks at the player's location and schedules a BukkitRunnable runTaskLater to set the light block back to normal air afterwards to get rid of the trail. My concern currently is on server disable, these delayed tasks are cancelled rather than ran, causing light blocks to remain in random places upon server restart.

Is there a good way to force these queued runTaskLater tasks to fire rather than to be cancelled? Doing a List of locations is definately an option but I feel like there's probably a more elegant way to go about it?

[kind hatch]

Packets would probably be your best bet.

That way the server doesn't ever actually have to update the world.

[young knoll]

Oh true

[kind hatch]

Covers the crash state too since saving a list of block locations isn't guaranteed.

[young knoll]

And you can then send another one to convert it back to air

Player#sendBlockChange

[kind hatch]

Who ever added that method to the api is goated btw.

[indigo axle]

I see, thank you! If I want to emulate it not being client-sided, I should just search for nearby players and send the method for anyone that's close, right?

[kind hatch]

Basically, yes.

[wraith dragon]

Does anyone know how to obfuscate with yGuard? Need help with setting it up and running

[rough ibex]

may I ask why you are obfuscating anyway

[wraith dragon]

prevent people from copy pasting my code

[rough ibex]

obfuscating doesn't do that

it can easily be bypassed

you already own copyright over your code

[wraith dragon]

perhaps

but to a normal person who doesnt have any experiene at all

would be effective

[worthy yarrow]

plugin ideas?

[tame wolf]

Toilets.

Dragons?

T&D!

[blazing ocean]

that's mods...

[tame wolf]

Its possible with a plugin

[blazing ocean]

eh

very hard tho

[tame wolf]

They wanted plugin ideas 🤷 didn't say what difficulty

[blazing ocean]

would need a custom model, ai, movements, etc

[tame wolf]

These are rookie issues, real professionals struggle with making the poop physics

[blazing ocean]

custom entities is very hard with plugins

[blazing ocean]

wha-

[nova notch]

its a good challenge

[blazing ocean]

i mean yeah

[nova notch]

here you go have fun

[quaint mantle]

Random dungeon generator ❤️

You can never have too many on the market

You can make a LOT of money with those

Pick a unique algorithm tho

[nova notch]

people buy that shit?

also thats a really good idea sounds like a fun project

[grim hound]

Are all PlayerEvents invoked in the packet handler?

[rough drift]

I could make one, been a while since I did anything with proc gen, ty for the reminder

[quaint mantle]

Some people pay 60$ a month for alienDungeons

So

Its a fucking gold mine

[shadow night]

a month?

[nova notch]

what the fuck

[shadow night]

Paying monthly for a plugin sounds like the most irrational thing a human with a working brain can do

[nova notch]

you might as well just pay a dev to make one for you

[shadow night]

True

A one-time payment is always better than paying 60 monthly lol

[nova notch]

making it yourself is more fun anyway even if it sucks

[quaint mantle]

A month.

[rough drift]

what's the difference between PICKUP_ALL and PICKUP_ONE

is PICKUP_ONE just whenever there is one item in the slot?

[sullen marlin]

I'm not actually sure how to get pick_one anymore

I think if you have an item on your cursor and then click the same item in a slot you might be able to under some circumstances

[eternal oxide]

Does scroll wheel allow you to add/remove one?

once an item is on your cursoe

[rough drift]

nope

[eternal oxide]

I must be remembering soem other game

[shadow night]

Nah

You are remembering the mouse tweaks mod or whatever it's called

[eternal oxide]

could be

[shadow night]

It adds exactly what you described

[rough drift]

left click -> PICKUP/PLACE ALL
left click on a slot with already some of the same type present, so the cursor can't empty -> PLACE_SOME

right click to place an item -> PLACE_ONE
right click to halve a stack -> PICKUP_HALF

collect all -> COLLECT_TO_CURSOR
swap a different type of items -> SWAP_WITH_CURSOR
drop items off the side of the screen with left click -> DROP_ALL_CURSOR
same with right click -> DROP_ONE_CURSOR


ctrl+q -> DROP_ALL_SLOT
q -> DROP_ONE_SLOT


shift+click -> MOVE_TO_OTHER_INVENTORY


number key or F with no item in destination -> HOTBAR_SWAP
with an item in destination -> HOTBAR_MOVE_AND_READD


middle click in creative -> CLONE STACK


clicking outside the inventory, clicking on an empty slot with left, right or middle click, or trying to hotbar swap with two empty slots -> NOTHING
```this is what I found so far

[sullen marlin]

Nice

If the docs are bad you could open a PR improving them

[alpine urchin]

Balderdash! All the docs are superb!

The docs shall never deplete in value. They are splendid and shall never stultify anybody that encounters them.

[blazing ocean]

PLEASE speak normally

[alpine urchin]

Have thee no genteel upbringing?

[polar forge]

Hi guys good morning

[rough drift]

I might, currently working on my own docs so it may take some time for me to PR

[charred blaze]

why is my plugin detected as virus?

[blazing ocean]

false positives

https://www.spigotmc.org/threads/windows-defender-false-positives.639507/

[charred blaze]

i mean

how can i fix it

already have seen that

[blazing ocean]

report it as not a virus

only thing you can do ¯_(ツ)_/¯

[charred blaze]

bruh

i have seen some plugin owners releasing an update for it

is there some kind of fix?

[pliant topaz]

It seems that PersistenData is bound to some other data, not only the item itself (atleast that's what I experienced)
Is it bound to the localizedName? as that would make the most sense to me

[vernal vessel]

Hi, I need help with debugging my plugin. I am debugging my plugin with intellij idea's remote debug, I added start flags to my start.sh, debugging works correctly but I dont know how can I apply changes to the code realtime to the server.

[rough drift]

nope

it's bound to the same stack instance

[rough drift]

iirc you need to build?

[charred blaze]

you dont?

[blazing ocean]

they're talking about hot reloading

[rough drift]

https://www.jetbrains.com/help/rider/Hot_Reload.html

that's rider

wait

[blazing ocean]

afaik you need a local dev server

[rough drift]

https://stackoverflow.com/questions/6402162/how-to-enable-intellij-hot-code-swap

[vocal dew]

ok waıt

[blazing ocean]

you don't need to rewrite it-

just read teh link I posted

[vocal dew]

I will read now

https://jd.papermc.io/paper/1.20/org/bukkit/event/server/TabCompleteEvent.html

[warm mica]

That tutorial tells you to you use java 1.7 (not 17) with 1.16.5🫨

[eternal oxide]

yeah its old, but everything is still relevant.

mostly the Eclipse and maven part

[vernal vessel]

restart what ?

[warm mica]

Do you realize what I said? It suggests to use a Java version that is 10 year olders than the minimum requirements of the spigot version. That tutorial sucks and shouldn't be used by beginners

[vocal dew]

Its a good tutorial and covers everything he needs

update that to 17 not 1.7

[paper crest]

Thanks

[warm mica]

Everything else may be good if it doesn't get the important things straight. It sucks if it causes more problems than it solves

[vocal dew]

hey i have spigot.jar Idk whats version i forgot lmao

[eternal oxide]

Not at all. Its a perfectly working tutorial, even if outdated everything in it works

[vocal dew]

help

[eternal oxide]

and its very simple to update

[warm mica]

"It sucks if it causes more problems than it solves"

[eternal oxide]

literally just changing java and spigot version

[warm mica]

What is the purpose of a tutorial if the person reading it has to figure it out after it causes problems?

[eternal oxide]

it doesn;t cause problems, it does exactly what a tutorial is supposed to do

Delivering wrong information is not what a tutorial should do

[eternal oxide]

its not wrong informations

[vocal dew]

please don't ignore me

[eternal oxide]

follow the tutorial, you have not added a repository

[warm mica]

That you are supposed to use 1.7 with 1.16.5 is not wrong information? Are you high?

[eternal oxide]

try reading a little past where it says 1.7

[warm mica]

That is even worse

1.16.5 minimum java is 17 if I remember correctly

[eternal oxide]

Dude, seriously?

[vocal dew]

ty fixed

but I forgot the spigot version xd how to find it

spigot.jar version

[eternal oxide]

you don;t need the version as a jar

you type the version you want in your pom

[vocal dew]

<version>1.16.5-R0.1-SNAPSHOT</version><!--change this value depending on the version or use LATEST-->

[eternal oxide]

follow the tutorial, its all explained

[vocal dew]

ok

[warm mica]

Ya, it is. It just shows that the person who wrote it doesn't really know himself what he is doing. "You really should use this extremely outdated version, but you might use this one that is outdated as well".

[vocal dew]

thanksss worked ❤️

ty for tutorial @eternal oxide

love u dude

[eternal oxide]

I'm suprised you got it to work so fast, but have fun.

[vocal dew]

I didn't read anything just followed the pictures LOL

[oak mica]

How would I get the warden entity

    @EventHandler
    public static void onPlayerPotion(EntityPotionEffectEvent e) {
        if (e.getEntity() instanceof Player p) {
            if(e.getCause() == EntityPotionEffectEvent.Cause.WARDEN) {
                
            }
        }
    }

[eternal oxide]

there is no warden entity in a potion effect

[oak mica]

?

[eternal oxide]

the player or entity, not the warden

[oak mica]

so theres no way to get the entity who gave the potion effect

[eternal oxide]

you'd have to listen to another event to get the attacking entity

[oak mica]

also how could I make a zombie attack other zombies

how to import the plugin to plugins folder?

how to make it jar

[blazing ocean]

show your code

[blazing ocean]

run the maven package thing or click on the build button

[oak mica]

gradle build

you can create yoru own and set it to clean package
