[proud badge]

or maybe hmm, how would I check if the area exists?

[shadow night]

maybe has("password") or something

[proud badge]

is jObject.get("password").getAsString() exists

[shadow night]

idk

[proud badge]

ye its has

thx

[hazy parrot]

There is getOrDefault

Or smth along those lines

Or just get(key, defaultValue)

[slate tinsel]

How can I check if a path belonging to a yml file is a config section or not

[glad prawn]

isConfigurationSection

[slate tinsel]

Thanks 🙂

[inner mulch]

singleton abstract classes aren't possible, right?

[minor junco]

they are*

kinda

[inner mulch]

how?

[minor junco]

public abstract class Test {
  
  public static final Test INSTANCE = new Test() {
    //...
  };
  
  private Test(){}
  
}

[inner mulch]

yeah but the new Test() will create a new object?

[minor junco]

I mean yeah, that's a singleton. Having at maximum one instance

[hazy parrot]

There is no point in abstract singleton

[minor junco]

idk what you're trying to achieve

[quaint mantle]

Hi , can others use ( login ) my uuid if they have my uuid ?

[hazy parrot]

Every uuid is public

[minor junco]

the point of abstraction is the disconnection between declaration and definition

if you're making an abstract singleton it basically is declaration & definition

thus it doesn't make much sense

[inner mulch]

i have classes that are the same that are singleton and i dont want to write the code for each one, therefore i was thinking to inherit the code

[quaint mantle]

i knew but can they login with my uuid ?

[hazy parrot]

No?

How would that make sense if uuid is public

[hazy parrot]

Then make child classes singleton, not abstract one

[shadow night]

You can instantiate an abstract class?

[minor junco]

well if you think about OOP you can just inherit a parent that has all the commonalities and make the constructor of your subclasses private and deny any more inhertiance

[minor junco]

yeah

in fact you can overload any object

[hazy parrot]

Yes, same as interface

[quaint mantle]

what do you mean ? because you said if get uuid can login with my uuid

[shadow night]

Damn

[inner mulch]

i guess i could make the child classes singleton but then i would have to write 4 lines of code each time :/

[hazy parrot]

I mean it's not really abstract class object

[minor junco]

  Object object = new Object() {
    @Override
    public int hashCode() {
      return 31;
    }
  };

[hazy parrot]

But a anonymous class which extends abstract one

[shadow night]

Damn

[hazy parrot]

When I said that

[minor junco]

well that's the pain of java

boilerplate and verbose code

[shadow night]

Wait, anonymous classes and functions are just those without a name?

[hazy parrot]

Hence ANONYMOUS xd

[minor junco]

lmao

[hazy parrot]

Lambdas are syntax sugar for making anonymous class

[shadow night]

Lambdas are generally pretty sugary

I based everything on top of lambdas lol

[minor junco]

as long as you don't end up in callback hell ig

[shadow night]

Lol

I was never in callback hell yet, besides javascript

[remote swallow]

Thats paper api

[shadow night]

It is?

[remote swallow]

Cancellation states like that are

[minor junco]

if you check out the new minecraft source code, it is full of lambdas and callbacks

the legacy code wasn't like this, but the new are since it got into fashion

[slender elbow]

no they aren't

[ivory sleet]

But thats fine, we have computation builders like monad patterns to avoid that pretty much

[inner mulch]

how do i make sure there are aliases, there is not hasAliases method? (yellow because of NPE)

[tender shard]

well the NPE is possible because getCommand might be null

[inner mulch]

oh

i guess

thats my problem if i dont register it

[tender shard]

you can safely use Objects.requireNonNull(getCommand(label), "Do not edit plugin.yml manually oyu imbecile!")

[inner mulch]

wait what ?

why shouldnt i edit my plugin.yml?

[tender shard]

no, its a message for admins

sometimes they think it's a good idea to change command names and aliases by editing the plugin.yml in the .jar

this might work fine if they only change the aliases and stuff like permissions, but if they change the actual command name, then ofc getCommand("mycommand") will return null

so you can tell them to not do it if getCommand returns null

[inner mulch]

oh

[tender shard]

alternatively just use an empty Objects.requireNonNull but I like to leave this warning for stupid admins lol

[river oracle]

Thats why you register through the command map :P

[inner mulch]

oh yeah thats nice

thank you guys

[opal juniper]

Is this exposed on spigot??

[river oracle]

No but it's like one method handle

[opal juniper]

Tut tut tut

[river oracle]

Actually 2 cuz you gotta reflect plugin command

But like still

[inner mulch]

can you use #getCommand(command) also with one of the main command's aliases to get the command?

[tender shard]

i doubt it

[steel swan]

hey so, i have this scoreboard code that makes certain player able to see life, which works perfectly, but now, i want certain other players to see a certain value on the below name slot. For instance, every player has a value assigned to him (a string value) and what i want is to display the players value on top of his head.

[inner mulch]

basically more nametag lines?

or do i understand wrong

[steel swan]

there is a below_name slot. here this code displays the health value.
i want to code it so that it doenst display the health value, but a custom String assigned to each player

[inner mulch]

yeah basically you want more nametag lines?

[steel swan]

?no?

im using the Below_name thing with scoreboard, i wanna use that

[inner mulch]

you want a string below the player's name

that's a nametag line

[steel swan]

oh mb so yeah

[inner mulch]

yeah, so i might be wrong, but as far as i know you can display stuff there but with the compromise of there always being a score a heart or whatever minecraft display type you use

i think if you want to freely create nametag lines with all the stuff that you want to type there, you would need to create fake nametags with armor stands or textdisplay

[inner mulch]

you still here?

[steel swan]

yeah i read what u wrote

ok so

what if i want it to be like this for instance :

PlayerName
1 stone

1 being the custom int i get from each players assigned value

and stone being the custom String value each player has

[inner mulch]

i think that is possible

Criteria.DUMMY

there is a string i think, and the number 0 next to it as the score

i would recommend creating your own nametags, its more customizable and less of a headache than this, but you could try the criteria

[steel swan]

ok so, for instance would this code to show the X coordonate of each player work?

[inner mulch]

i dont know you can try, if it doesnt work, im here to help :)

[steel swan]

ok so i achieved to show the player each players coordonate, by modifying the score.
But i have NO IDEA how to modify the displayName of the objectif for each player

cuz if i juste do setDisplayName it will change it for everyone

[inner mulch]

tbh just code your own nametags its much less of a headache, if you still want to stay with scoreboards, im not really able to help you as iam not super experienced (with scoreboards)

[steel swan]

the problem with nametags is that all players can see it right?

[inner mulch]

no im talking about your own custom nametags, if you would do that and design a proper system you can have as many nametags as you want

and code everything as you like

[steel swan]

OK so with ur name tags could i do that ONLY 1 player sees every other player with the name tag PlayerName and a custom string that is different for every player?

[inner mulch]

you can do everything, you can let one player see not nametags at all another see different nametags and one see everything normal

[steel swan]

OK so then, i d need to use packets correct?

[inner mulch]

packets are safer, as if your server crashes these nametags would be gone too

if crashing is no issue and you dont care having millions of armorstands after a crash floating in the air you could use the api too

[steel swan]

ok so one other question. TO use packets like PacketPlayOutPlayerInfo what do i need to import?
Cuz when just importing PorotocolLib API i cant access it

what else do i need to import

[inner mulch]

i dont know all the imports it depends on what you are doing with the packets

what exactly happens when you are trying to use protocllib

[steel swan]

but i think i saw somewhere i had to import smth like CraftBukkit or smth

[inner mulch]

i wouldnt recommend using nms

[steel swan]

why?

[inner mulch]

you should use protocollib

[tender shard]

?nms

[undone axle]

https://blog.jeff-media.com/nms-use-mojang-mappings-for-your-spigot-plugins/

[inner mulch]

it changes every verison

it will make you insane

[tender shard]

what do you even need that packet for?

[steel swan]

idk he told me to use packets

[inner mulch]

i didnt tell you to

[tender shard]

for what?

[inner mulch]

i told you what happens if you dont

[inner mulch]

.

[steel swan]

i want just 1 player to see everyone name tag like :

PLayerName and next to it a String that is specific to each player ( that i get from a hashmap )

[tender shard]

i'd use a displayentity that has a custom PDC tag so you can delete them if they're accidentally leftover

[steel swan]

like i create an entity displaying it?

i want to alter the display name, not just show smth next to it

[tender shard]

yes, just spawn a TextDisplay

[tender shard]

oh then I misread

[steel swan]

i want to alter the players display name, no way of doing that?

wait

[tender shard]

i only saw that you were talking about "leftover entities" or sth so I thought you wanted to use packets instead of creating normal entities for holograms

[tender shard]

idk

[steel swan]

Player#setdisplayName() is a thing would it work?

[tender shard]

it only changes the name in chat and tablist iirc

but not over the player model

[steel swan]

OK

so i d need to use Packets for that correct?

[shadow night]

Does it change it in chat?

[steel swan]

cuz i want just 1 player to see those custom names

so were back to my old question, what do i need to import to use

[tender shard]

Not in vanilla but chat plugins would use it i guess

[tender shard]

?nms

[undone axle]

https://blog.jeff-media.com/nms-use-mojang-mappings-for-your-spigot-plugins/

[tender shard]

And then use the proper name

?switchmappings

[undone axle]

https://blog.jeff-media.com/switching-from-spigot-mappings-to-mojang-mappings/

[steel swan]

imma be honnest , i dont really understand how to import nms

[tender shard]

or are you using gradle?

[steel swan]

nah maven

[tender shard]

did you read the blog post?

[steel swan]

but usually i just modify repistory and dependency and thats all

[quaint mantle]

yeah

[steel swan]

yeah but the whole maven part i dont really get

[quaint mantle]

that's what you do

Im pretty sure you first install the NMS code locally

[tender shard]

which part exactly don't you understand? I mean it tells you to run buildtools, then it tells you what to add to your pom, and that's it basically

[steel swan]

ok then, to start, where do i run the buildtool

[tender shard]

1. Run BuildTools with --remapped flag
2. Add the specialsource plugin (the <plugin> thing) into your <build><plugins> including that config
3. Add the dependency for remapped-mojang

[quaint mantle]

im kinda confused tho how does buildtools register the nms into your local repository

[tender shard]

doesnt matter. anywhere on your PC

btw: latest buildtools has a GUI now

[steel swan]

what do you mean anywhere , in my cmd for instance?

[tender shard]

1. download latest buildtools
2. run it with double click
3. select version, and select remapped in the settings
4. click compile, wait until it's done
5. now you can move to the stuff where you change your pom

be sure to check this

[steel swan]

like ok when i click it, i have this? no download or anything

[tender shard]

yeah tbh the download link is quite hidden in the text

[steel swan]

found it

[tender shard]

I said thousand times that the whole article needs to get yeeted and replaced with a simple
"Download BuildTools here: <link>"

[steel swan]

ok so its compiling

[tender shard]

did you check the remapped flag?

[tender shard]

this?

[steel swan]

yes

[tender shard]

ok good

[steel swan]

i enabled it in the potions

options*

[river oracle]

yeah :P you can see their args at the top of the console

[tender shard]

then you can now wait 3 minutes

[steel swan]

ok while its doing that should i start modifying my pom?

?paste

[undone axle]

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

[tender shard]

yes

[steel swan]

i dont have to wait until the end?

https://paste.md-5.net/iyilewoquf.xml here is my current pom

[tender shard]

well you can't use it until buildtools is done but ofc you can already start changing your pom

[steel swan]

what do i need to add

[tender shard]

read the blog post pls

you need to add the specialsource-maven-plugin into your <build><plugins> section

and then you have to change your spigot dependency to use artifactId "spigot" with classifier "remapped-mojang"

[steel swan]

the whole

thing?

[tender shard]

yes

[steel swan]

i get this error : org.spigotmc:spigot-api🫙remapped-mojang:1.20.2-R0.1-SNAPSHOT was not found in https://repo.dmulloy2.net/repository/public/ during a previous attempt. This failure was cached in the local repository and resolution is not reattempted until the update interval of dmulloy2-repo has elapsed or updates are forced

[tender shard]

as I said, the artifactId is spigot and not spigot-api

[steel swan]

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

i did this and now have those errors :

Could not find artifact org.spigotmc:spigot🫙remapped-mojang:1.20.2-R0.1-SNAPSHOT in dmulloy2-repo (https://repo.dmulloy2.net/repository/public/)

[tender shard]

has buildtools finished?

[steel swan]

no, is that why?

[tender shard]

yes

[steel swan]

ok ill get to u when its over

[quaint mantle]

wtf

[tender shard]

the purpose of buildtools is to create that dependency and install it on your computer

[quaint mantle]

i dont remember having to do all that

for nms lol

[tender shard]

then you probably used one of those "illegal repos" that host the spigot dependency

[tender shard]

or you've been using paper's gradle plugin that basically does more or less the same as buildtools

[tender shard]

now you can reload your pom

and then you're done

although I see that you still haven't properly read the blog post because your pom is still incorrect

[steel swan]

oh mb the version

[tender shard]

yep 😛

now if you reload the pom, it should find the dependency

[tender shard]

I see. you have added the whole remapping part into the maven-shade-plugin

that's wrong

[steel swan]

i copied what was on the site

i dont get what i did wrong here..

[tender shard]

this is one <plugin> section

you have only copied the executions part and pasted it into another plugin

[quaint mantle]

i just installed it locally

thats all i remember

then included it in dependneis

[tender shard]

yeah well installing locally = running buildtools

[steel swan]

oh i see

[tender shard]

all of the selected text is one plugin. do not just copy parts of it and put it into another plugin - copy/paste the whole thing

[quaint mantle]

oh wait

ur re obfuscating

thats why

[tender shard]

yes sure, mojang maps

[steel swan]

ok it ran

[tender shard]

aint nobody wanna deal with a() b() c()

[quaint mantle]

thats what i worked with 💀

[tender shard]

RIP

mojang maps give you proper method names, and they will be consistent over updates

[steel swan]

Ok now its installed

[quaint mantle]

but I wasn't that knowledgably prepared anyway

like

the most I did was send an action bar

since 1.8 doesn't have that

[tender shard]

yeah 1.8 api lacks many things

and mojang maps are only available in spigot 1.17 and newer

[steel swan]

so now , if i wanna send custom packets to a certain player to change other players nametag, what do i do?

[tender shard]

no clue

well i can tell you how to send packets

[steel swan]

cuz what i see online tells me to use PacketPlayOutPlayerInfo

do u know how to send PacketPlayOutPlayerInfo ?

[tender shard]

Okay so PacketPlayOutPlayerInfo is the old name

check out this tutorial, it will explain how you can find out the correct name:

?switchmappings

[undone axle]

https://blog.jeff-media.com/switching-from-spigot-mappings-to-mojang-mappings/

[tender shard]

dw it's short and easy lol

[steel swan]

dont see anything tho

[tender shard]

dude you really need to learn to properly read

you always just read 30% and then wonder why you missed certain steps

[steel swan]

bro i just did what i saw here

[tender shard]

then why is your search bar in your screenshot set to Mojang and not Spigot?

[slender elbow]

cap

[steel swan]

ok mb i didnt see it

[tender shard]

if you would just read my tutorials (read EVERY sentence in the correct order), then there will be no questions left lol

if however you just take quick glances at the code snippets or the screenshots, then ofc you'll miss all the important information

[steel swan]

ok what am i dont wrong then..

[tender shard]

hm seems like PacketPlayOutPlayerInfo isnt the correct spigot-mapped name

where did you get that packet name from?

[steel swan]

from a spigot forum

[dry hazel]

it's for <1.19.3

[steel swan]

Ohh yeah ok i found the packet i need to use

[steel swan]

do u know how to send them ?

[tender shard]

you can try to use ClientboundPlayerInfoUpdatePacket, maybe that's the correct one

(that's already the mojang mapped name)

[steel swan]

yeah i figures

figured*

Like for instance, if i wanna try smth simple, like putting everyones name to red

[tender shard]

as I said, i dont know which packet you need for that, I haven't messed with changing player's names. I can only tell you how to setup mojang maps (which we did now) and how you can use that website to translate the PacketPlayOut... names into the proper names

[manic delta]

Java or spigot has some limitation in the JAR? I am making a POST request in my plugin and testing the jar in a Test class everything works fine but inside the server (localhost) no, I don't have a cloud server at the moment so I can't test it there.

[tender shard]

probably windows firewall?

spigot doesnt mess with outgoing http requests or anything

[steel swan]

ok.

i might

have done a lot for nothing

@tender shard if i wanted to add a prefix to a player name (or suffix) would that require packets?

[tender shard]

i think you can do that with scoreboard teams

[steel swan]

so i put all players in teams and create a prefix for each team?

[kind hatch]

Yea

[steel swan]

wont that have any repercution on the game?

[tender shard]

no

[steel swan]

ok and that will change it also on top of the players head? or just in tab

[tender shard]

just create one team per player, set each team's prefix/suffix to whatever you like, then set each team's Option.NAMETAG_VISIBILITY to "for everyone" https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/scoreboard/Team.html#setOption(org.bukkit.scoreboard.Team.Option,org.bukkit.scoreboard.Team.OptionStatus)

[steel swan]

oh wait

[tender shard]

i think it should work for the name above the head too

[steel swan]

but then i have a problem

i want only 1 player to be able to see this prefix

or suffix

[tender shard]

then add these 2 players to one team and set the visibility to "only same team"

[steel swan]

yeah but i cant put 1 player in different teams right? cuz i want to make this 1 player see everyones teams

[tender shard]

players can be in multiple teams

[steel swan]

wait ok that would help me a lot

[tender shard]

you would create one team per player and set all their visibility to "same team", then you take the special player and add them to all teams you created

[steel swan]

i need to create 1 variable per player or how

[elder harness]

Quick question: Adding to a location does NOT give you a copy, right? It gives the original one?

[sterile token]

How do You get a player instance, if the one using the name is deprecated. And since that, you can't get the uuid

[rotund ravine]

Yes

[rotund ravine]

It’s deprecated cause names cna change

Not because you shouldn’t use it if you absolutely need to

[sterile token]

I perfecto understamd, buts is clown that. Becuase how do You get uuid if You can't player object with his name? 🤔🤔

[elder harness]

You have to get it by UUID. If anything you can't, and the player has been on the server before, you can loop over the offline players on the server and filter by name. Then grab the first from the filter. Note that this is unsafe, since (as mentioned before) names can change

What are you trying to do? It seems like your design has a flaw or your approach is bad practice

[tender shard]

why?

[tender shard]

correct

[rotund ravine]

Again

[steel swan]

u told me to create one team per player

[rotund ravine]

If you do not have the uuid

Use the name

[sterile token]

Nope, i havent seen any plugin where You ban players by taking his uuid as an argument for banning. Have You? I mean i don't see that really good approch

[tender shard]

yes. I would use a Map<UUID,Team> to store the teams you created

[sterile token]

Most of time i ask why spigot does weird things on their api

[elder harness]

Use the Mojang API to get the UUID by a current player's username --> https://wiki.vg/Mojang_API#Username_to_UUID

[rotund ravine]

Again

[chrome beacon]

Spigot already has API for this

[rotund ravine]

It was deprecated cause names can be changed now

Not because you shouldn’t use it

[sterile token]

Right thanks. Why isnt already implemented on api? More reasons for not using public apis

[steel swan]

so doing just this wont work?

[rotund ravine]

But you should prefer uuid when possible

[elder harness]

Oh really? I was unaware

[rotund ravine]

It is

[sterile token]

i'm lost Jan sorry

[rotund ravine]

I mean getOfflinePlayer has always done this as well as the new PlayerProfile stuff

[sterile token]

So i use get player vía name without any issue. Thanks

[steel swan]

oh and also, there would be 1 problem with what u told me to do. I want just 1 player to see teams, but then everyone would see His team too

[sterile token]

thanks to spigot i have yo disable the shity deprecated warning

[rotund ravine]

Yes, if there is no other way sure

[elder harness]

Does "Bukkit.getPlayer(String s)" provide this?

[rotund ravine]

You’ll encounter that a lot more

[rotund ravine]

No

getOfflinePlayer or smth

[sterile token]

SO for getting player what do i use

[rotund ravine]

Use PlayerProfiles though, there you can control it a bit more

[rotund ravine]

Depends

[sterile token]

Offline or Player

[rotund ravine]

What makes sense in your application

[sterile token]

For example a banning plugin, they use Offlineaplayer right?

[rotund ravine]

Well, it could do

[elder harness]

Damn, I have been making http requests to that endpoint on the Mojang API my whole life and there is a method for it? Damn...

[rotund ravine]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/Bukkit.html#createPlayerProfile(java.lang.String)

[sterile token]

But You have told me that getPlayer name is deprecated. How i would it be a "could be"

[rotund ravine]

Again, you should prefer ways in which you do not attempt to ban with a name of an offlineplayer. In most cases it will be just fine though

[sterile token]

So i can just vía name get offline player and ban it. Isnt that ok?

[rotund ravine]

In most cases that is just fine

[sterile token]

Right thanks i was asking about that.

[manic delta]

yea prob is that

[kind hatch]

What does that last line say?

[remote swallow]

windows by default makes you use ondrive

[young knoll]

Move it outside of onedrive

Like the C folder or somethin

[rotund ravine]

Desktop is onedrive by default

[young knoll]

Or do what I do and yeet onedrive

[grim hound]

Can I somehow create a Proxy class that'd have it's methods invoked without using an actual class instance? For example I just input "Map.class" and every method invocation of that class of any instance is delegated there

[rotund ravine]

?

[grim hound]

So that I don't need to input an actual instance to the Proxy

[grim hound]

I explained it

Have the Proxy class have it's methods invoked

On any instance of the given class

[rotund ravine]

Why

[grim hound]

Without passing in the class' instance

[grim hound]

Is it possible?

[young knoll]

Probably?

[rotund ravine]

A lot of things are possible

[young knoll]

With a lot of dark magic

[kind hatch]

Next on the todo list. More obvious error messages.

[grim hound]

Then how?

[rotund ravine]

Give us a good reason

[grim hound]

No

I just need it

I have no idea how I'll use it yet

[orchid gazelle]

make it red and fat

and put a fat ERROR!!!!!!!!!!!!!!!!!!!:

[grim hound]

Because I haven't tested how it works

But for now it's absolutely necessary

[kind hatch]

I had a screenshot of a potential error message format in the GUI thread.

[grim hound]

For example any method on any Map class will be invoked on that proxy instance

Without giving any map instances to the proxy's creation

[young knoll]

So it has to find all map instances

[rotund ravine]

Seems like ur trying to do something useless

[young knoll]

That’s probably a lot

[grim hound]

It was just an example

[grim hound]

That's disrespectful

[rotund ravine]

No

[young knoll]

I mean I’m sure you could find all instances of a given object at runtime

But like

[hazy parrot]

Why not just... Extend HashMap

[young knoll]

😩

[hazy parrot]

If you want to do some nasty things

And override methods

[grim hound]

Because it was just an example

[grim hound]

Dynamic classes

[hazy parrot]

¿

[grim hound]

What do you not understand?

Okay, does any of you know how to do this?

[hazy parrot]

I'm unfamiliar with term dynamic class

[grim hound]

Does anyone know?

[rotund ravine]

Give us an example on how it would work with some pseudocode it seems weird

[hazy parrot]

Thing you explained earlier is basically done by extending HashMap

[grim hound]

I literally explained exactly what I wanna do

[hazy parrot]

Then you have solution

[grim hound]

I'm asking you for the advice

[rotund ravine]

Shadow you gotta remember not everyone lives inside your brain

[grim hound]

Why the fuck would I be asking that question if I could do that?

[young knoll]

Are we like

[hazy parrot]

Why ask me that

[young knoll]

Generating classes at runtime via asm

Am confusion

[quaint mantle]

How can I get offline players from all servers with bungeecord?

[hazy parrot]

That is only thing I can think of when I hear term dynamic class

[grim hound]

Well no, I just wanted to implicate that the classes are not the same so nms stuff

Different names

[young knoll]

plugin messages

But that requires a player on each server

Otherwise something like redis

[quaint mantle]

messages?

[young knoll]

?pmc

[undone axle]

https://www.spigotmc.org/wiki/bukkit-bungee-plugin-messaging-channel/

[quaint mantle]

I have connected the pl to a mongodb

to ban him also if is offline

in bungee

[grim hound]

You could send a list of player nicknames

[grim hound]

Through this

Seperate them with like ";"

[young knoll]

Can’t you just handle the bans on the proxy

[grim hound]

And then find the one you wanna ban

[young knoll]

^

You can even handle the ban checking on the proxy

[quaint mantle]

yeah

Thats the idea

[young knoll]

Idk

But you can just connect to a database

Don’t really need messaging

[proper cosmos]

But why? It's pretty non sense. You would need to go through every object in memory and get them.

[quiet ice]

You people really have no idea how this dark magic works

[young knoll]

Google probably does!

[quiet ice]

Yes, it's completely possible - what the hell even is the point of using a Proxy class then? Just beware that if you wrap an HashMap, it will be proxied as a Map - not as a HashMap

If you are really unsure chances are you can easily generate the needed code via ASM (or comparable) - the code can then be dynamically loaded via MethodHandles.Lookup#defineClass

Did you forget to reobfuscate your jar file?

If so, you are out of luck - this is spigot, not paper. In paper world you need to use paperweight and as such the procedures differ.

how can that even compile?

Please don't say you are using reflection in this day and age

[slender elbow]

eclipse compiler will give you the option in a silver platter to compile even if there are errors

[quiet ice]

That would throw an assertion error iirc

Well you're wasting your own time and that is basically all

Making use of Mojmap will allow you to develop like everything else without risking any typos and having to wrangle with obfuscated names

?mojmap I don't know if there is a command for that though, but does not hurt to try

[river oracle]

https://blog.jeff-media.com/nms-use-mojang-mappings-for-your-spigot-plugins/

[quiet ice]

Yeah

oh god, don't tell me you are using your IDE to build your stuff

Sadly we do not have AW/AT/whatever access in runtime.
Would be cursed anyways

mojang's official deobfuscation mappings

it breaks with every update

[undone axle]

Compare different mappings with this website: https://mappings.cephx.dev

[young knoll]

Technically you can get away with not updating sometimes

But I guess that also applies to reflection

[unkempt burrow]

how to change player skin using packets?

ty

[grim hound]

The objects would all be created after the interceptor

[young knoll]

So it’s not every object in memory

[grim hound]

Well it is

[grim hound]

All of the given instances of a class would only be created after the interceptor

[vapid grove]

Im having an issue:
My vein mine code for a pickaxe isnt taking away the tools durability. Any reason why?
https://paste.md-5.net/ojizobuzip.cs

Notes: There is no error, but it just doesnt account for durability when breaking a tree.
I thought that breakNaturally would break it naturally, and account for the tool used, but It doesnt seem to be.

[kind hatch]

The tool parameter is used for calculations with enchantments. It won't change the durability as the parent method #breakNaturally() just breaks the block and spawns the item.

[vapid grove]

I see, how would I simulate durability then, that is also affected by the factors of:

• The tools durability enchantment level
• If the tool has the unbreakable stat

[kind hatch]

You could try using Player#breakBlock()

[vapid grove]

Ill try that right now

[vapid grove]

This works, thank you!

[remote swallow]

wrong dependency

?nms

[undone axle]

https://blog.jeff-media.com/nms-use-mojang-mappings-for-your-spigot-plugins/

[remote swallow]

you dont need the minecraft-server dep

you need a spigot dep

read the blog page again

you dont need it

all you need is the spigot dep and the special source plugin

have you ran buildtools

with --remapped?

?paste your pom

[undone axle]

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

[remote swallow]

no

craft server is the craft bukkit impl

for the actual entity EntitiyPlayer is the spigot mapping, ServerPlayer is the mojmap

[vapid grove]

And now im even more confused.
After doing the change, I then made slight improvements to my code.
https://paste.md-5.net/afeziracej.cs

Now, sometimes only 3 pieces of wood get broken, sometimes it only goes up to where the leaves come, its not breaking all the wood.
Any idea why?

Notes: EnchantmentManager is just the handler ive created for custom enchants in the plugin, that code works and the main issue is in veinMineWood.

[young knoll]

Keep in mind Player.breakBlock will fire another block break event

[vapid grove]

Hm. okay.

[minor junco]

Location is mutable. You need to create a copy of the location when performing arithmetic operations through the clone method

[young knoll]

Depends on how you get it

[minor junco]

I swear 95% of all location related issues stem from location being mutable

[vapid grove]

So I need to clone the location first?

Then add onto it

[minor junco]

Try if that fixes your issue

[young knoll]

Block.getLocation.add should be fine

Since getLocation returns a clone

[minor junco]

Player.getLocation doesn't or didn't in legacy versions at least

Idk why the code would be inconsistent

[young knoll]

Hmm

[minor junco]

But I'd say just give it a try

[vapid grove]

That worked I think, imma try it a couple more times.

[minor junco]

Alright

[vapid grove]

Yeah it seems to randomly not work, it stops randomly thru it.

Ill send my updated code.

[minor junco]

That's seems like a separate issue then

[vapid grove]

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

[minor junco]

If there's a change in behaviour the block location is definitely backed

So what's the issue now

[vapid grove]

Its doing the same thing.

I cant send screenshots however

[young knoll]

?img

[undone axle]

Can't send images? That's because you're not verified! Use !verify to complete verification.
Alternatively, you can upload screenshots to any image hosting site and share the link.

Here's some screenshot utilities that you can use to upload images.

[inner mulch]

if two objects are exactly the same (same class and same data in them) will the hashcode be the same?

[vapid grove]

It said my accounts already verified

But I never verified it

[minor junco]

Depends on their hashcode definition

By default, no

Unless it's a record

[vapid grove]

Ohhh thats why, I verified on an older account that ended up being thrown away.

[inner mulch]

okay

[vapid grove]

@young knoll Is there any way I can reverify for this new discord account?

My old one was deleted and that one was the one I verified one back in march 2020

[young knoll]

You’ll have to contact higher up staff

Or

?support

[undone axle]

[e-mail]

[vapid grove]

Ah okay

[minor junco]

The hashcode is just the object's VM memory address by default I think

Used for referential equality

[vapid grove]

Smae issue as before, its just not breaking all the blocks.

It seems to end randomly.

And now for some reason its not dropping blocks for #breakBlock() either

[minor junco]

What does that mean end randomly?

What's your goal here?

To break an entire tree?

[vapid grove]

My goal is to vein mine any blocks that are wood

Its a vein mine for logs

I realize why its doing that now and I feel very stupid.

order of operations.

Nope that didnt fix it either

[young knoll]

Remind me to yoink Chocos vein mining code at some point

[vapid grove]

Thought maybe it was because i was breaking the block first but now tis not working at all

[minor junco]

So it just stops working?

[vapid grove]

Yeah.

[minor junco]

Try to debug your startBlock and is wood function

[remote swallow]

@young knoll reminder to yoink chocos vein miner code

[young knoll]

Lol

Cheers

[minor junco]

Might be that the types differentiate without you realizing

[placid quartz]

This was in the past the case. No longer do they do this.

[vapid grove]

Alright

[young knoll]

What’s the default hashcode impl now then

[minor junco]

What are they using now?

[remote swallow]

Objects.hashCode

[placid quartz]

In Java 8 you could check with some flags and by default it was an XOR-Shift algorithm

[minor junco]

That was using the memory address as a baseline no?

[placid quartz]

No it was a seed

If you started a new VM it was always the same

[minor junco]

Ah alright

Then I've been mistaught

[young knoll]

I like to use the current system time in my hashcode

[minor junco]

Or misunderstood

[young knoll]

Make it nice and unpredictable

Kek

[placid quartz]

But yes it was memory based

[minor junco]

Used to be, alright

I understand

[ivory sleet]

Its the same as System::identityHashCode in principle

[placid quartz]

Also you could make your own VM and change the implementation if you wanted to

So I wouldn’t rely on it

[vapid grove]

@minor junco Print statements are only returning grass blocks and such, no logs whatsoever.

Which is odd.

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

Note to self: Become a script kiddie and steal someone elses vein mine code lmao

[heavy void]

Someone knows why BoostedYAML removes String?

Ex: Transforms "stringexample" into stringexample

[ivory sleet]

But thats in general a very bad argument as vms should aim to be consistent with the api

[river oracle]

Because It's redundant in yaml

[young knoll]

Usually*

[ivory sleet]

If a vm impl changes general api behavior then thats a bad vm

[young knoll]

Sometimes SnakeYaml adds quotes

I think it does when the string has a :

[heavy void]

I mean values

[river oracle]

Yes

Exactly what I said

[heavy void]

Theres any way to disable this change?

[river oracle]

Ask the author

[minor junco]

Very odd indeed

[heavy void]

Ok

[vapid grove]

Whats even odder:

While the drops arent being made, durability is still affected.

I pissed off the api 💀

thats my conclusion

[young knoll]

Sounds like you are breaking air or something weird

[minor junco]

Erm

[vapid grove]

Thing is my code checks to see if the object is a log or not

So how would I get the ability to break air

 public static boolean isWood(Material material) {
        return switch (material) {
            case OAK_LOG, SPRUCE_LOG, BIRCH_LOG, JUNGLE_LOG, ACACIA_LOG, DARK_OAK_LOG, STRIPPED_OAK_LOG,
                    STRIPPED_SPRUCE_LOG, STRIPPED_BIRCH_LOG, STRIPPED_JUNGLE_LOG, STRIPPED_ACACIA_LOG, STRIPPED_DARK_OAK_LOG ->
                    true;
            default -> false;
        };
    }

[minor junco]

A wild solution: break the block after interating over your range

[vapid grove]

Tried that and then it just

didnt work at all

[minor junco]

What?

[vapid grove]

Yeah

ill try again but

it broke it when i did

[minor junco]

Have you tried to debug the outcome of isFuncs.isWood? Maybe the types are different

For some reason

Try printing the type and the result of that invocation

[vapid grove]

I have not I will try right now

@minor junco https://paste.md-5.net/dogivitipe.cs
The prints are returning, and it is attempting top find blocks to vein mine, but it just doesnt do so.

Ill reword:

• Its able to find blocks to mine
• It does invoke the function to attempt to mine

[minor junco]

So it finds all the blocks but it doesn't break them all?

[vapid grove]

Hold on

Imma try something

[minor junco]

@vapid grove imma sleep now but please feel free to keep me updated, quite interesting

[vapid grove]

So.. I realized it might be going into an infinite back and forth loop.

[minor junco]

Oh erm

[vapid grove]

Of finding the same wood

And I tried making a table of wood that has been located already

[minor junco]

yeah but it is getting broken

[vapid grove]

And not letting it attempt to vein mine it.

And my server crashed...

[minor junco]

So it shouldn't

[vapid grove]

private void veinMineWood(Block startBlock, Player player, HashMap<Location, Boolean> veinMines) {
        Material woodType = startBlock.getType();
        veinMines.put(startBlock.getLocation(), true);

        if (isFuncs.isWood(woodType)) {
            for (int x = -1; x <= 1; x++) {
                for (int y = -1; y <= 1; y++) {
                    for (int z = -1; z <= 1; z++) {
                        Block currentBlock = startBlock.getLocation().clone().add(x, y, z).getBlock();

                        if((x + y + z != 0) && veinMines.get(currentBlock.getLocation()) == null && currentBlock.getType() != Material.AIR && isFuncs.isWood(currentBlock.getType())){
                            veinMineWood(currentBlock, player, veinMines);
                        }
                    }
                }
            }
        }

[minor junco]

If you break it before iterating

[vapid grove]

Ah

Ill give you updates as I figure out why its doing this lol

[minor junco]

Yeah please

[young knoll]

Wait why is it a map instead of a set

[vapid grove]

honestly

i do not know

just decided to use a map idk lol

Im going to try recoding this from scratch

[spare mason]

how can i freeze the player?

[young knoll]

Like stop them from moving?

[quaint mantle]

wtf

[young knoll]

Set walk speed to 0 and give jump boost > 128

[vapid grove]

?

[young knoll]

Or jump boost -1, don’t remember which of those work

[quaint mantle]

just a tip but try to make your code not so nested

if (!isFuncs.isWood(woodType)) {
return;
}

called gaurd clauses im pretty sure

[remote swallow]

thats early returns

[vapid grove]

Oh I see

Thank you, ill try doing that instead

[quaint mantle]

i think they're basically the same

@vapid grove

[vapid grove]

Ohhh

[vapid grove]

@minor junco My last update on this:
Coll called it, the reason it wasnt working was because player.breakblock calls the blockbreak event, and caused an infinite loop breaking the code.
After switching back to breakNaturally and instead just manally lowering durability for the item, it works fine.

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

[young knoll]

You could also just use a Boolean to ignore the break event

[vapid grove]

How so?

[young knoll]

set Boolean
Player.breakBlock
un set Boolean

And then ignore event while Boolean is set

[vapid grove]

thanks lol

Few questions:

Should I work with shorter names or keep these long names

Is this a factory method? I'm asking this because you can register your own session/persistent data factories before initialization

is this a good system or nah

[rare rover]

Max 🤨

[quaint mantle]

What

[rare rover]

Hi

[quaint mantle]

Hi

[rare rover]

See you in minehut discord every once and a while

I would help but I'm on my phone and cant see anything

[quaint mantle]

lmao

I can explain you the system

PitPlayer:
DataContainer persistentData
DataContainer sessionData

yeah then you can add your own data to the player's data containers, but you should register them to their factories

So when the player joins all the data loads

[rare rover]

Ah

Let me hop on my laptop rq

I'll be more useful

[quaint mantle]

The data container api follow these 3 classes

DataFactory
DataContainer
DataContainerProvider (might rename to factory who knows)

So it might look like this

interface PersistentData
class PlayerStats impl PersistentData
class PlayerStatsFactory impl DataFactory<PlayerStats>

DataContainer<PersistentData>
DataContainerProvider<PersistentData>
dataContainerProvider.registerFactory(PlayerStats.class, new PlayerStatsFactory())

And so on

[inner mulch]

Set<Object> randomSet = randomSetHashMap.containsKey(uuid) ? randomSetHashMap.get(uuid) : new HashSet<>();```

Is there a cleaner way to do this?

[river oracle]

what are you trying to do

[inner mulch]

i need to get a the set from the hashmap, but i dont know if there is one

i want to know if this is the cleanest approach

[river oracle]

randomSetHashMap.getOrDefault(uuid, new HashSet<>());

[inner mulch]

oh

thanks

didnt know that existed

[river oracle]

depending on what you want to you could probably use Map#putIfAbsent and then Map#get after

[inner mulch]

okay, i will be going to implement these cleaner methods

[river oracle]

generally though getOrDefault works best if you aren't going to edit the sets at all

if the sets are mutable and you plan to mutate their state I'd reccomend the second approach

[inner mulch]

oh

[river oracle]

otherwise getOrDefault is perfect since it prevents non null values

[inner mulch]

i was going to mutate them actually

final ubuntu setup

what yall think abt it

[river oracle]

L distro choice

https://cdn.discordapp.com/emojis/730775621780635690.webp?size=48&name=CH_KekLaugh&quality=lossless

in all realness though looks good

[astral scroll]

tbh i like ubuntu cuz is user friendly

[river oracle]

I'm not used to default gnome xD it looks so polarizing

[astral scroll]

i don't really need something so hacker or idk

[remote swallow]

Ew ubuntu desktop

[astral scroll]

:(

[river oracle]

I mean for reference this is the same display environment

like we are both using gnome

I just customized mine a bit

[astral scroll]

yeah

well idk

i'll just stay with what i have until i get tired

[river oracle]

are you fully on linux?

[astral scroll]

ig i could get a windows-ish look with some apps? don't really know about customizing ubuntu

[astral scroll]

nope, i have win11 for fortnite and gta lol

[river oracle]

kek I dual boot for Siege and Some other games

[astral scroll]

lol

that's only thing good abt windows

[river oracle]

I acutally got genshin impact working on linux at one point

[astral scroll]

its compatibility

[river oracle]

https://cdn.discordapp.com/emojis/705059720007909377.webp?size=48&name=CH_PepeShhh&quality=lossless

[astral scroll]

insane

but well

it runs on phones

[river oracle]

but it's not supposed to beable to run on linux

[astral scroll]

put genshin on a freezer lol

[astral scroll]

its not but yeah

you got it

HAHAHA

[river oracle]

I stopped playing though since It got boring after 300-400 hours

[river oracle]

yeah and it only really even has that because of its monpollistically large market share

[astral scroll]

BRO

THAT'S A SHITLOAD OF HOURS

[astral scroll]

yeah ig

but yeah

dualbooting is really good

but now i gotta reinstall epic games and rockstar

on windows

cuz i formated from win10

[river oracle]

do you do it on separate drives? because otherwise it can get fucky

[astral scroll]

nope

same 500gb drive

and it works pretty well

[river oracle]

I'd actually reccomend going to get a new drive if possible eventually

beacuse windows likes to override grub sometimes

[astral scroll]

yeah i want to get an 1tb nvme

other than the 500gb nvme i have

but they're expensive

im saving for it

[river oracle]

you can get a pretty nice one from Western Digital for like $60

which isn 't bad tbh

[astral scroll]

yeah that's the same price i have here on colombia

but i'll check it out

but im on laptop

don't really now if i can add one

never opened it before

[river oracle]

might be saudered

I'd reccomend just saving for a desktop

it'll take longer but def be worth

[astral scroll]

nah

im entering college 2025

[river oracle]

or buy a Thinkpad

[astral scroll]

damn a thinkpad

never thought of it

[river oracle]

they are good because you can replace parts

most laptops sauder parts

[remote swallow]

Framework

[river oracle]

thinkpoads generally don't

[astral scroll]

bro ive seen

that laptop

of modules

don't know the name

but they got a pretty good idea

imagine being in class

[river oracle]

Thinkpads are used in business so you can guarentee the parts won't dissapear either

[remote swallow]

Thats framework

[astral scroll]

and just start disassembling your laptop mid class

[astral scroll]

oh

i'd like to have one of them

[river oracle]

Blegh making that your whole shtick is annoying. I'm assuming you can only buy parts from them though

[remote swallow]

Probably

[river oracle]

yeah see ThinkPad is better in that sense because I could just buy parts from elsewhere. Though I'd prob just buy from lenovo till they stop selling the parts

[remote swallow]

If you move a lot framework is good because it will last and when stiff breaks you can just replace it and upgrade

[astral scroll]

i think a full laptop without extra parts

its

$9000 usd

but yk

you can dissasemble it on starbucks

lol

[river oracle]

@remote swallow actually doesn't seem bad tbh

looks like you can use whatever parts you get your hands on

[remote swallow]

Id hope so bc ltt invested like 100k or smth in it

[river oracle]

I think I'll buy one of these next. Maybe I'll save up and get one for my GF

[remote swallow]

Is this a pineapple dev promotion

I ought to try and get kubuntu or fedora on my chromebook again

[young knoll]

Im sorry why are we disassembling a laptop on top of Starbucks

[remote swallow]

Why not

[astral scroll]

HAHAHAH

cuz we can

Not related to coding but I was curious if there was a way to make a quest book look better?
ItemStack is an enchanted book named "Quest Book" with green text.

Lore is:

Quest Difficulty: (easy medium or hard recolored to be fitting)
Quest Info: Mine Iron Ore
Progress: 50% complete. (5/10) (recolored based on the percentage of completion)

I cant send images cause I gotta get my verification fixed lol

[round finch]

Thank you!

i totally forgor
about searching it up before asking
lol that what happens after long time of non coding

[peak moth]

Hello, looking for some guidance here so bear with me. I have a chat channels plugin that I am looking to add Bungeecord support to, previously, I had used the plugin messaging channel which worked relatively ok but not sure if it scales well. Essentially, any time an update occurs to a global channel, I simply want to propogate that update to all servers (such as new member joining channel etc.). I've seen some people have a project that is able to load into Spigot and Bungeecord servers with seperate build paths for both. However, I am not sure if I really would need a proxy plugin to achieve this or if it would be better performance since I am just unfamilar with proxy plugins. Any advice is appreciated

[proper cosmos]

Idk what exactly interprecetor is 💀 but you could just add Annonnation and at initiation of your code you add them to list

[wet breach]

ideally you should avoid adding plugins to the proxy server

the proxy is only there to do one job, and you shouldn't add to it if its not needed

to accomplish your goal you just need a DB server

[grim hound]

You don't know what an interceptor is?

[dry hazel]

no

no idea what it means in this context

[quiet ice]

It's what is on the tin: It intercepts the call of a method

https://github.com/Starloader-project/smatterDI/blob/main/src/main/java/org/stianloader/smatterdi/CDObjectAllocator.java would be another of my numerous examples of a generated interceptor

Although that one achieves it via subclassing, not by proxying or wrapping

[dry hazel]

knowing the use case would probably help

a proxy with an invocationhandler that calls the original methods would be the most straightforward if you control the instantiation, otherwise read the class file and pop your code where you want it and redefine - bytebuddy can do it easily if you're not familiar with bytecode

[minor junco]

Ahhh I see

[fluid cypress]

i made a plugin bc i needed to change the biome of large areas based on an image. i used Block#setBiome, but for some reason, even after reconnecting or restarting the server, the biomes dont change unless i make a change to the chunk (i assume), like placing a block (or something like that, i didnt test it too much tbh, i just set min Y to bedrock just to try stuff out). any idea why does that happen? any idea how to apply the biomes without placing blocks? placing blocks makes like 2 or 3 times slower, not a problem but idk, id like to know why that happens

Uhh with the spigot api you mean? How is it different to restarting the server?

[chrome beacon]

Reconnecting or restarting should fix it

Make sure you're running Spigot and that you're up to date

also you can always share your code so we can try to recreate the issue

[fluid cypress]

Well, actually its not spigot

It is a purpur server

[fluid cypress]

Not on my pc rn

[chrome beacon]

try recreating the issue on Spigot

[fluid cypress]

But its just a simple for loop with block.setBiome depending on some conditions and thats it

[fluid cypress]

Ok, ill do it later just to be sure

[rough drift]

I keep forgetting, but how do you rotate a vector around itself? Imagine this is a top-down view, and the black line is where the vector is currently pointing towards, how could I rotate it such that it goes in the direction of the red line?

[chrome beacon]

Add the vector between the two points

[rough drift]

I don't have the 2nd point, I only have the black line and an angle

I should've explained better lmao

[chrome beacon]

point refering to the tip of the arrows

[eternal oxide]

Spigot has helper methods for this

RotateAroundY

[rough drift]

oh

Thanks lmao

[rare rover]

Wtf

Is this new???

I've literally never seen this

[eternal oxide]

not new

[eternal night]

feb 2019

that is after 1.8 release so, thats new, basically an infant of a method

[river oracle]

Yeah its good :P

[halcyon hemlock]

hello humans*

[sage dragon]

How would I go about changing a tool's speed and breakable materials?

(For example, a wooden pickaxe that acts like an Iron Shovel)

[umbral ridge]

Modify the item attributes

[astral scroll]

hello :)

[smoky anchor]

You don't
Best you could probably do is a resourcepack that adds a custom model data for the items to make them look like different ones.
But this item property is client side and not modifiable
If you do change it for the server, there will be desyncs

[chrome beacon]

You can give mining fatigue and then calculate breaking on the server

It works quite well

[smoky anchor]

Or this painful solution
Which is lag dependant tho

(has noone made a library/api (dunno correct term) for this ?)

[chrome beacon]

I would rather have delay for break start than block desync

[chrome beacon]

I've seen it done in Minestom

[sage dragon]

All hail Minestom

[sage dragon]

Hmmmm, that's bad :/

[sage dragon]

Painful... But I'll try it, I guess

[proud badge]

what do yall think would be better, if I need 33% chance on something should I get a random number between 1-100 and check if its below 33, or just get a number between 1 and 3 and check if its 1?

[echo basalt]

just make 1 in 100

and move on

that's how percentages work

[proud badge]

Ok

[young knoll]

Or use nextDouble and .33 :p

[quiet ice]

That is if you want to be really precise

[solid cargo]

Or just gen 1 to 3

If its any of those numbers (choose one) then boom

[minor junco]

The higher your upper bound the more "true" your random will seem, so I'd go 1-100

[glossy venture]

Math.random() <= 0.3333333333333333333333D

simplest

[young knoll]

Gotta go all out

0.33333333333333333

[glossy venture]

oh true

[proud badge]

Does this return a boolean?

[glossy venture]

yeah

its compares it

[proud badge]

ok so true if the 33% chance happens?

[glossy venture]

yes

<= always returns a boolean

[glossy venture]

no we need full precision Math.random() <= 1.0/3.0

[young knoll]

oh yeah

[minor junco]

IEEE hates this trick

[quaint mantle]

0.1 + 0.2 = 0.3000000004

[minor junco]

Gotta love floating point issues

[quaint mantle]

I tried this trick on banks

/j

[minor junco]

well banks usually use two integers to define a decimal value

[rough drift]

How can I get the block before a raytrace hits?

[raven jolt]

How do you register custom enchantments in spigot 1.20.4?
I used to do it like this:

public static void registerEnchantment(Enchantment enchantment) {
        
        boolean registerd = true;
        
        try {
            
            Field f = Enchantment.class.getDeclaredField("acceptingNew");
            f.setAccessible(true);
            f.set(null, true);
            Enchantment.registerEnchantment(enchantment);
            
        } catch(Exception e) {
            registerd = false;
            e.printStackTrace();
        }
        
        if(registerd) {
            // send message to console
        }
    }

However Enchantment.registerEnchantment doesn't exist anymore

[eternal night]

you don't

you can try to hack your way there via NMS

[young knoll]

Or use PDC

[tender shard]

i think i got too many projects open

[tender shard]

the only valid reason to register your own enchantment is to create a "dummy" enchantment to apply the glow effect to items that contain your other custom enchantments, which should be using PDC instead

[shadow night]

Doesn't using nms for enchants break every version

Because of relocation

[tender shard]

you were able to register enchantments just fine using spigot-api and one line of reflection, until 1.20.3 came

NMS is not relocated btw

only craftbukkit is

[shadow night]

Wasn't it tho

[tender shard]

i think it was until 1.17

[eternal night]

"register"

[tender shard]

create, whatever

[eternal night]

I mean yea, API "registration" was scuffed af anyway

[tender shard]

is there a better way to check if a file is a jarfile, except by creating a JarFile and checking for exceptions?

[eternal night]

not really

the logic to read the zip header is not exposed elsewhere I think

[minor junco]

You can add method declaration and definition to classes outside their class scope in Kotlin?

[tender shard]

alrighty thx

[tender shard]

yes

[minor junco]

Oh that's cool

Similar to Rust

[tender shard]

for example, here I declared String.placeholders(...)

and here's how one can use it:

[minor junco]

But I unfortunately hate the rest of Kotlin so not gonna program in that unless im forced to by my workplace

[tender shard]

iirc the compiled code is just a static function that takes in "this" as first parameter, e.g. String.doSth() would become public static void doSomething(String $$this)

[minor junco]

Ah okay, makes sense

If you'd use Kotlin and java interchangeably it might be a mess no?

Since the Kotlin compiler is doing so much bytecode magic

[chrome beacon]

Yeah using Kotlin stuff from java is pain

[minor junco]

Yeah no thank you, I'm staying with my old java 😂

[tender shard]

Using java classes in kotlin is fine, other way around is probably not so great lol

[wet breach]

it depends. Since the java spec is already outlined in what is to become what in terms of java bytecode, for the most part it only needs to worry about transcribing kotlin specific stuff

[dry hazel]

it's possible to design idiomatic java apis with kotlin as well

[eternal night]

Extension methods surely are a great concept

[dry hazel]

e.g. minestom's Hephaistos (NBT library)

[tender shard]

what's wrong with them?

[eternal night]

I find the concept of object methods outside of the scope of the object concerning given nothing guarantees you the score of the extensionmethods is imported

You end up with nice syntax sugar sure

but they just become messy as fuck imo when overused

[tender shard]

there isn't really a difference between these two:

class FileUtils {
  public static boolean isJar(File file) { ... }

and this

fun File.isJar(): Boolean { ... }

You'd either import FileUtils and use FileUtils.isJar, or you import your extensions class and use myFile.isJar()

and ofc the IDE will tell you it's a method declared in another file

[eternal night]

Yea but the name of say extension class is completely unknown

like, from my end as a consumer

[tender shard]

how is it unknown? You import it like you'd import any other class

[eternal night]

if a documentation references new File().isJar() i have 0 idea that I have to import FileUtils so I can use said extension function

that problem does not exist if I use a proper static method

I always know exactly what type that function is part of

[tender shard]

then you'd have to blame the documentation that advises you to use random extension function sthough. Kotlin's builtin extension functions don't need to be imported, and your own ones also don't need importing if they're declared in the same package

[eternal night]

I mean sure ?

its just more hassle for little to no gain imo

[tender shard]

idk i never had issues with not knowing where my own extension functions come from

[eternal night]

Yea because its your own codebase lol

I also don't have issues knowing where my stuff is

[river oracle]

I mean its fine if you organize them in utility classes still

you probably shouldn't just throw them around in random classes

than you can direct to Utility classes you can use as both Extension functions and used normally as regular functions

[eternal night]

guess so. ¯_(ツ)_/¯

in the end it just hijacks the syntax of object methods for a static method

[river oracle]

yes and It's fucking great

[eternal night]

as great as inventory PR

[river oracle]

speaking of Inventory PR

the only place I really wish I had this was actually with NMS

cuz then you can just slap extension functions on the related classes

[river oracle]

Inventory PR will be the greatest thing in Bukkit history though stupid question nothing is as great as Inventory PR

[eternal night]

[tender shard]

biggest PR of history was goat horn api

[eternal night]

fastes merge of a lifetime

[river oracle]

well I figured goat horn API was a given

that API was very important its the foundation of modern spigot

[tender shard]

all those stupid 1.8 players cant use goat horns lol

they dont even know what theyre missing

[river oracle]

lol idiots and their goat hornless version

[tender shard]

yeah stupid plebs kek

[eternal night]

pfft, 1.8 players don't even have PDC or sendTitle

[river oracle]

yeah but like who tf cares about that s hit

[eternal night]

Well, you could also have ItemStack#removeEnchantments

[tender shard]

i wonder if this works - can I really just turn a file from resources into a file object?

[dry hazel]

resources can be turned into a File only if they are an actual file

[river oracle]

I wanna know how a resource can't be a file wtf are you people storing in the resources directory!!

[dry hazel]

well you can have resources in JARs or outside

you can't reference it as a file if it's in a JAR

[tender shard]

sad, that would be very handy

can't i do it with a JarFileSystem or however its called

[dry hazel]

yea

[wraith dagger]

Hi

how to get location list in config.yml

?
