[young knoll]

Yeah pretty sure that’s how it goes

Methods are similar but letters often get reused

Which is annoying

[tender shard]

yeah if there's no signature conflict, it will use a as often as possible

[young knoll]

Who tf runs .3

Buildtools doesn’t even build it anymore

[mellow edge]

How would I cancel player walking particles without events, is player walking a server-side packet or not?

[young knoll]

Other players particles probably send a packet

But your own are probably client side

[hybrid spoke]

could also be that its hardcoded in the client, that player characters have walking particles by default

[mellow edge]

If they are server-side would I have to intercept a packet before sent and not send it?

[hybrid spoke]

that would block it, if you want to achieve that

[mellow edge]

Yeah there are no events afaik

[hybrid spoke]

but looks like its clientside

[mellow edge]

I mean even if they are clientside for the player itself, I just need others to not see it

[hybrid spoke]

which you cant do if its clientside

you could try some hacky way like intercepting the player position packet and set on ground to false

maybe that removes the particles

[tender shard]

yes, that's always a good idea. I usually use sth like this to do it:
https://github.com/mfnalex/JeffLib/blob/master/core/src/main/java/com/jeff_media/jefflib/ReflUtils.java

[mellow edge]

Do you mean it is clientside for all players not just the player itseld?

[hybrid spoke]

yeah

[mellow edge]

Then I will just leave it

[tender shard]

ofc that only works if you know the field name. So you'd wanna rewrite this to get a field by type if you wanna do it like that.

If you only need to cache one field, then I'd just do it like you already did

sth like this for example:

    private Map<Class<?>, Field> fieldsByReturnType = new HashMap<>();
    
    public Field getFieldByReturnType(Class<?> clazz, Class<?> returnType) {
        return fieldsByReturnType.computeIfAbsent(clazz, c -> {
            for (Field field : c.getDeclaredFields()) {
                if (field.getType() == returnType) {
                    field.setAccessible(true);
                    return field;
                }
            }
            return null;
        });
    }

then you can just do getFieldByReturnType(ServerGamePacketListenerImpl.class, Connection.class)

and it also caches it automatically

yeah that's what you need now, what about tomorrow? 😛 I'd just throw that code above into a ReflectionUtils class and then use it. even if you only use it once, it'll declutter your actual class

[mint nova]

    @EventHandler
    public void onBlockBreakDrop(BlockDropItemEvent e){

        if(e.getBlock().getType() == Material.COAL_ORE) {
            e.getBlock().getDrops().clear();
        }

        if(e.getBlock().getType() == Material.IRON_ORE){
            e.getBlock().getDrops().clear();
        }

Can anyone can help me?

So i trying to check the material in the one if with array or || but dont work

[chrome beacon]

Show what you tried

[lost matrix]

Im still trying to understand the last sentence..

[mint nova]

i dont know english very well

[mint nova]

sec

[chrome beacon]

They want to combine the two if statements to prevent duplicate code

[lost matrix]

Ah ok. Then lets see what he tried so far.

[mint nova]

this array is ngl bad i think but yea i forgot how to do it

[hybrid spoke]

you would have to loop over the list and check each

and for the OR you have to write an actual condition

not just the material

[lost matrix]

[chrome beacon]

Just use contains with a material list?

[lost matrix]

List is a collection which means you can just call contains(Object) on it

[hybrid spoke]

true tho

could even use a EnumSet

[chrome beacon]

Don't do that

Material is not guaranteed to stay an enum in the future

[hybrid spoke]

mimimi material will be gone mimimi

[lost matrix]

A normal HashSet is preferred now over an EnumSet because material wont be an Enum for very long

Ah

[hybrid spoke]

in the current state of spigot an EnumSet would be the best option

but yeah use a hashset then

[lost matrix]

So your solution is:
Create a List<Material> or Set<Material> as a field (not as a variable in your method)
and then call contains(Object) on this List or Set. I think in your case it doesnt really matter if you use a List or Set.

[worldly ingot]

Yeah you probably won't get a noticeable performance benefit either which way, but a HashSet is technically the correct implementation to use here given you're using it exclusively for #contains() operations

Lucky for you, there are factory methods in Java 17 😎

private static final Set<Material> ORES = Set.of(Material.COAL_ORE, Material.IRON_ORE);

[young knoll]

Im pretty sure material is going to stay an enum

Just be deprecated

[worldly ingot]

Correct, but you still won't reap all that much benefit from an EnumSet because the Material's universe is so large

[mint nova]

Ok

[minor junco]

yeah that would just lead to you creating an enormous array from which you may only need 2 indexes

[worldly ingot]

[mint nova]

whyyyy

[worldly ingot]

Outside the method

[mint nova]

oh

mb

[mint nova]

can i just do loop for contains(Object)?

idk how to say it

[minor junco]

if you want to check if a material is contained in your collection, use contains

advantage from using a set is your lookup being O(1), meaning it doesn't grow in complexity with the amount of elements there are added to it

[chrome beacon]

No need to loop

[mint nova]

so i just like would put one?

[minor junco]

for example:

public boolean isOre(Material material) {
  return ores.contains(material);
}

and, depending on what you want to achieve with this, you can for example test against a block broken, or clicked, or whatever by using Block#getType() which returns the material

[mint nova]

ohh

[minor junco]

so basically, if you inline your method:

if (ores.contains(event.getBlock().getType()))
  // ... do something with ore

[tender shard]

anyone know how I can fix this?

[river oracle]

Remove the suppression

Or switch it to all 😎

[tender shard]

the issue is that getMainHandItem is annotated with NotNull but I've seen cases where that's just not true

[slender elbow]

i'd like to see that being the case because it is never null

@Override
public ItemStack getItemInMainHand() {
    return CraftItemStack.asCraftMirror(this.getInventory().getSelected());
}

public static CraftItemStack asCraftMirror(net.minecraft.world.item.ItemStack original) {
    return new CraftItemStack((original == null || original.isEmpty()) ? null : original);
}

[tender shard]

not in spigot, but in stupid spigot/forge hybrids

[slender elbow]

why do you care about supporting those

[tender shard]

because if it's just a simple additional null check, then why not

[rough ibex]

You can either do a null check or say spigot/forge is out of scope and not supported

or ignore the warnings

I can't think of any other options.

[young knoll]

You could tell the hybrids to get their shit together

[tender shard]

alright alright I'll just ignore it kek

[deep herald]

anyone know how to set the attack speed of a hit?

[spare hazel]

is there a way to increase a fireball's damage using the spigot api?

[white mountain]

    @EventHandler
    public void onEntityDamageByEntity(EntityDamageByEntityEvent event) {
        if(event.getDamager().getType() == EntityType.FIREBALL) {
            event.setDamage(200.0D);
        }
    }

maybe?

[white mountain]

You will maybe need to change the attribute of the item u are using to change that

[spare hazel]

btw do Fireballs have PDC?

[white mountain]

PDC ?

[agile anvil]

Doesn't all entityhave PDC?

(but what the point of using pdc for a fireball since it's lifetime is really small?)

[spare hazel]

then how can i tag a fireball to modify its damage

[agile anvil]

Just save the reference to this fireball in a variable

[spare hazel]

its not 1 fireball

[agile anvil]

In a list then

[spare hazel]

@Override
   public void onRightClick(PlayerInteractEvent e) {
      HypixelPlayer playerAccount = HypixelCustomItems.getSkillCore().getPlayer(e.getPlayer().getUniqueId());

      if(playerAccount.getMana() < getManaCost()){
         e.getPlayer().sendMessage(ChatColor.RED + "Not Enough Mana");
         return;
      }

      playerAccount.setMana(playerAccount.getMana() - getManaCost());

      Player player = e.getPlayer();
      Location spawnAt = player.getEyeLocation().toVector().add(player.getEyeLocation().getDirection()).toLocation(player.getWorld());
      Fireball fireball = (Fireball) player.getWorld().spawnEntity(spawnAt, EntityType.FIREBALL);

      fireball.setIsIncendiary(true);
      fireball.setBounce(false);
      fireball.setShooter(player);
      fireball.setDirection(player.getEyeLocation().getDirection());
      fireball.setVisualFire(false);
   }```

[agile anvil]

I don't know how is your architecture but you have multiple choices.

1. Use PDC to Tag this fireball
2. Use a list of fireballs in somewhere
3. Use a list inside your player object
4. Other

There are plenty possibilities. Take the one that fits the better for your structure

The easiest one and most understandable one would be to use PDC

[spare hazel]

alright thanks

[agile anvil]

And this Fireball is an entity, it implements a PersistantDataHolder interface

from which you can Fireball#getPersistentDataContainer

[trim quest]

hello does anyone know how to make multi version support project with maven multi module. like that ?

[white mountain]

Hi how to draw text on the screen ? like this https://imgur.com/a/MbNPZWc

[smoky anchor]

Font magic

[white mountain]

https://www.spigotmc.org/threads/maven-nms-tutorial.347254/ maybe

[agile anvil]

Those "HUD" are drawn using custom fonts that can "move" the text. They're displayed through titles, action bars, chat or even bossbar/scoreboard

It's quite tricky to get it correctly but once you did that in place it's quite straightforward

[trim quest]

i saw this but is it looks like to my project?

i mean hierarchy of modules

[white mountain]

and for image drawing ?

[agile anvil]

For reference of the negative chars : https://github.com/AmberWat/NegativeSpaceFont

[agile anvil]

Those are also fonts. You can put pretty much anything in the font

[white mountain]

okay thx !

[agile anvil]

The idea is the following : draw gray background chars, input negative chars to move to the left, right text you want (can include custom chars). (you can also adapt along up/down and right/left)

[white mountain]

And so on we need the player download a ressource pack with the font in it

[agile anvil]

Right

Only drawback. But I truly enjoy all the possibilities the resource packs bring nowadays and encourage you to use them

(You can also take advantage of it by adding new items, etc)

[remote swallow]

https://blog.jeff-media.com/maven-multi-module-setup-for-supporting-different-nms-versions/

[trim quest]

that was very helpful thanks

[smoky anchor]

Heyo guys
How would one go about creating a resourcepack server-side and then sending that to the player
without the need of uploading it somewhere and then putting the link to server properties
A link to some resource would be appreciated

[sullen marlin]

You need to upload it somewhere

[agile anvil]

Never saw a public plugin doing so. you can decompose it in three steps:

1. Generating the resource pack
2. Expose this resource to the internet : you can wether create an HTTP server, or push the resource pack to some hosting content
3. Make a plugin that send the corresponding resource pack to the player when it joins

[smoky anchor]

Well that sounds hella complicated
Thank you for this guide tho

[agile anvil]

What do you want that for ?

[smoky anchor]

Nothing specific really
Just in case I ever want to use resourcepacks, I don't want to bother updating it on some host manually
Was hoping some easy way (an existing plugin or something) already exists to handle that for me

[agile anvil]

Then you'll maybe find some more help in #help-server -> People often share plugins or existing tools!

[smoky anchor]

Actually, I remember homosexualdemon's MusePulse plugin does this
Looked through sorce, he used SparkJava and it is literally just 4 lines of code for the host
So that's great! :D

[misty garden]

Hi everyone,

I want to create an economy, and this one you earn when you kill players, break a culture, with a kind of percentage

How can I do it?

[wet breach]

By being dedicated, vigilant and tenacious

[misty garden]

It's not what I'm looking for, but rather your advice on how to create this plugin.

[wet breach]

my advice would probably be the same

this isn't a place to be spoonfed

[native ruin]

Vault had an economy api maybe use that

[misty garden]

But I already have an economy that uses Vault, (essentials)

[fringe spruce]

hi guys,can someone help me out with a listener? So,i am creating a sort of handcuffs custom item and the last thing that I need to do is the listener that listens when a player right clicks on another player,can someone tell me what is the best event that I could use to create that?

[eternal oxide]

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

[smoky anchor]

Mind you, it can (probably) fire twice for each hand, so handle that too somehow.

[eternal oxide]

?interact

there is a helper for this 🙂

?interactevent

[undone axle]

The PlayerInteractEvent may be called once per hand. If you only want code to be executed once, you can check the result of https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/player/PlayerInteractEvent.html#getHand(), then decide functionality.

For example, only executing code if the main hand was used:

@EventHandler
public void onPlayerInteract(PlayerInteractEvent event) {
    if (event.getHand() != EquipmentSlot.HAND) { // * if the hand used is NOT the main hand:
        return; // do not progress past this point  |
    }
    // provide functionality
}

[fringe spruce]

i need to create a "on right click with that item " event

listener*

[native ruin]

Why does item frame have server operator interface?

And is it usefull for anything

[shadow night]

probably because it's an entity and you can execute stuff as an entity using the execute command

[smoky anchor]

Ok, use the events then
There is no PlayerRightClickedWithItemCalledCuffs, you have to make checks for that yourself

[shadow night]

event.getItem(): 😑

[tepid ore]

You can just proxy it otherwise, that's what I do. Works equally fine 🤷‍♂️

[clear elm]

i need help i have a little problem... I have an velocity network and me or the 2 nd owner uploaded an plugin with an cryptominer exedently and now every plugin on every server has an javassist package , the javassist package is the cryptominer . can i just replace all plugin jar file or have i reinstall every server

[eternal oxide]

replace all jars

[clear elm]

only in pluggin folder?

or all jar

[eternal oxide]

and don;t get plugins from bad places

[clear elm]

so only plugin jar casue server.jar hasnt the javassist folder

[eternal oxide]

They can't easily infect teh server jar as that is active when their injection happens

[clear elm]

i shut the server down and only the plugins are infected should i send one infected plugin?

[chrome beacon]

We don't need your infected plugin

Delete all jars on the server

plugins, libraries, servar jar etc

[clear elm]

damn

so i can basicly reinstall it?

[hushed scaffold]

if you dont mind the playerdata and worlds then sure

but you could just delete all the jars

[clear elm]

umm i put very much effor in the server

[hushed scaffold]

then replace just the jars

[clear elm]

can i keep the folders from the plugin?

[quiet ice]

Generally yes

[clear elm]

ALL jar files?

[hushed scaffold]

All

[icy beacon]

Hey, probably a simple question but I know next to nothing about this topic. Is it possible to buy a domain and attach it to my VPS? I want to get a domain and then an SSL certificate for it and before I actually go ahead and buy a domain I was wondering if that's possible at all. If there are any articles on the matter I'd appreciate

[quiet ice]

Only rarely will plugins be smart enough to also inject stuff there

[hushed scaffold]

except for the server jar

[quiet ice]

Including the server jar

[clear elm]

mojang_1.20.1.jar like even this in cache folder?

[hushed scaffold]

isnt it running during injection?

[quiet ice]

The cache dir can be nuked no problem

[quiet ice]

You can still alter the contents of it

[hushed scaffold]

ah

[clear elm]

how im suposed to get all the new jar files

[quiet ice]

Just how you got them in the first place?

[eternal oxide]

ONLY download from reputable sites, like Spigot

[hushed scaffold]

^

[clear elm]

many jar files were there before i became the server

[hushed scaffold]

especially dont download cracked paid plugins

[quiet ice]

Uh, via DNS it should easily be possible

[hushed scaffold]

a lot of stuff can be autogenerated on server run

[icy beacon]

Can you briefly outline the steps I should take?

[quiet ice]

As long as you have a stable IP address there is no issue at all

[clear elm]

ig i download all plugin folder and reinstal server than i upload new good plugin and upload the folders

[hushed scaffold]

pretty much yeah

[quiet ice]

Get the VPS and Domain (from the same provider is usually the simplest) and see from there

[icy beacon]

I already have a VPS but they do not sell domains

I have just an IP address and a subdomain of theirs

I mean I will most likely be moving away from that vps soon

[quiet ice]

Then go with any reputable domain provider

[eternal oxide]

thats all you need

[icy beacon]

Because it fucking sucks

[wet breach]

it would help if server owners learned about security

[quiet ice]

Hertzner should provide that alongside DNS

But CF and anything else works too

[chrome beacon]

Cloudflare is nice

[spare prism]

?paste

[undone axle]

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

[clear elm]

how can i download folders?

[chrome beacon]

From where

[quiet ice]

Tarball them?

[clear elm]

plugin folder

[wet breach]

here is a service script that lets you launch as many server jars as you want, modify to your needs but be mindful of the security settings in it. This service script is designed to prevent processes from doing anything outside of its directory its running in. This means if you get an infected jar again it only affects the server and plugins for that server and not everything outside of that. Also prevents the process from being able to see outside of its directory as well along with it can't modify its perms it started with

https://gist.github.com/frostalf/74d662a4bf381ad4ba2679bc537c4595

[chrome beacon]

zip them

[quiet ice]

Id be surprised if they knew anything about systemd

[chrome beacon]

They're probably just using a Minecraft host

So pterodactyl

[clear elm]

yea

[quiet ice]

Perhaps they even have a negative opinion of systemd

[spare prism]

why doesnt my custom event get called?

listener: https://paste.md-5.net/ovukisidiw.java
the event itself: https://paste.md-5.net/hocakivunu.java
calling the event: https://paste.md-5.net/bucaguzefa.coffeescript

[wet breach]

not sure why unless they just don't know how to use it?

[wet breach]

makes sense I suppose on the lack of security

[hushed scaffold]

ooh thats neat

[wet breach]

also restarts the process if it dies 🙂

[hushed scaffold]

:o

does it allow to also force close all processes of that directory?

[wet breach]

well since its a service, the script can kill the process at will

the odds of it ghosting is minimal

[hushed scaffold]

seems like the perfect tool to install pirated jars ( joke )

[wet breach]

well systemd is just a service handler

all processes started under systemd isn't above it

so this means if systemd wants a process to die that it has control over, it will most surely die but it does require a user still to have the appropriate permissions depending on the type of service

[quiet ice]

Well a lot of Linux "influencers" are bound to not like systemd (like X11). And if that is the only source of information they may have (given no hands-on experience exists) that is the opinion they could have

[hushed scaffold]

so if systemd is run as admin and the user is admin it should kill any process under it?

[wet breach]

Well systemd already runs as admin well kind of

it has two different sides to it

it has system services, and then there is user services

I suppose also network services

anyways, the root user can always kill systemd if they wanted to I guess but to do that you would need to install another system handler

but any processes started from systemd, is killable by systemd if it needs to do that. A user can always force kill processes especially root, just use the nice command

as long as you respect the categories for the services and use them appropriately you shouldn't have issues with a process becoming a ghost. Always a pain dealing with them ghosts >>

[eternal oxide]

I aint afraid of no ghosts.

[wet breach]

maybe not, doesn't mean getting rid of them isn't a hassle though

typically ends up you need to reboot the system to just get rid of them XD

so typically what you do if you can't get rid of the ghost process is you just ignore it

pretend its not there, consuming the small bit of resources and you keep doing that until you need to reboot to free up those resources if it starts consuming too much 🙂

[eternal oxide]

Silly, you call teh ghost busters. Have you not seen the advert?

[wet breach]

Yeah, but not sure if I want to risk them destroying stuff >>

maybe if like something important depended on the server not rebooting then maybe

[raven vessel]

@vagrant stratus how do i set up a premiumconnector bungeecord plugin in minehut

[wet breach]

instead of pinging random staff members that are not here

why don't you ask minehut?

or the author of whatever plugin you are trying to use

[raven vessel]

ok

[kindred valley]

How can i grt the itemstack of the placed block in blockplaceevent

[smoky anchor]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/event/block/BlockPlaceEvent.html#getItemInHand()
probably

Try reading the docs a little too

[kindred valley]

i use 1.7.10

Ah wait there actuslly is the method there too

[wet breach]

could use material?

getType()

[kindred valley]

Ah yes i just remembered it.

[smoky anchor]

https://howoldisminecraft1710.today/

[kindred valley]

How do i do uhc pvp plugin without using 1.7

I have to do

[wet breach]

why do you need 1.7 for it?

[smoky anchor]

no you don't
they didn't remove the pvp past 1.7

[kindred valley]

its not the same

[smoky anchor]

you can still fight people

[kindred valley]

The rod is literally 2x thicker

[wet breach]

yeah obviously that is the point of updates, to not be the same as the previous otherwise what point was there to provide updates?

[kindred valley]

They probably didnt even make 1.7 version for pvp but that version is the best of the best of pvp

[main juniper]

Who’s spending 3 dollars a year on that domain

[dire marsh]

there is also https://howoldisminecraft188.today/

[slender elbow]

a wise person

[wet breach]

pvp wasn't really a thought out mechanic, hence being able to just spam click. However it makes sense when the game isn't designed centrally around pvp to begin with and rather just a fun feature added that was is not meant to be some hardcore pvp thing XD

[wet breach]

people who like owning domains

[main juniper]

Ok

[umbral ridge]

hi frosted elf are you in cali yet

[wet breach]

why would I be in Cali?

[kindred valley]

If everybody spam clicks then its no longer spam click but mechanic of the game. Thats what makes the 1.7 a pvp game.

[umbral ridge]

why would you not be in cali

[wet breach]

because Cali sucks

[umbral ridge]

XD

[kindred valley]

Isnt there colorful wools on 1.7

?

[wet breach]

fuel prices are high because the citizens of the state decided to vote for a stupid tax that increases every year for 10 years. Cali is trying to outlaw the combustion engine even though there is no public transport to get from one end of the state to the other and its power producing abilities sucks right now and they make it nearly impossible for gas stations to setup EV stations so even if you wanted to go EV you won't get far due to lack of power and ev stations lol

[wet breach]

you have your basic rainbow colors

[icy beacon]

I'm trying to get an SSL certificate with Certbot and install it to the domain provided by my vps. I now have a certificate (fullchain.pem) and a private key (privkey.pem). I have no idea what to do next. Certbot gives this instruction but seeing as I have absolutely no idea what I'm doing, I'm failing to understand where I can find this file

[kindred valley]

Wdym there is wools on the game but not in spigot

[wet breach]

should be in ./certs

[smoky anchor]

you need to use the magic meta number thing irrc

[wet breach]

1.7 uses damage values to distinguish the variants

[dire marsh]

oh the joys of legacy api

[icy beacon]

Where is that, like the absolute path?

Or is that the absolute path

[wet breach]

that is the path

[icy beacon]

Yeah I don't have that..

[wet breach]

what about certificates?

[icy beacon]

Nope

What is the file supposed to be, at least the name or the extension

[wet breach]

hmmm.....check the directory you ran the command for certbot

[wet breach]

you should have the pem files

[icy beacon]

I am talking about the instruction prvided by certbot

[wet breach]

there should be 2 pem files and a key file

[icy beacon]

I know where my pem files are

[kindred valley]

Do.you mean flattening after 1.13?

[icy beacon]

But struggling to understand step 7 (screenshot)

[young knoll]

Yes

[wet breach]

you need the 2 pem files and in the webserver configuration you input the path to them

[young knoll]

We love the flattening

[icy beacon]

Yes.. that's what I'm asking. WHat is the webserver configuration? Is it a file or something supposed to be provided by the hosting?

[wet breach]

depends on what webserver you are using

[quiet ice]

Do you even have a webserver?

[icy beacon]

Probably not. Just a VPS

The tech support fucking sucks ass

[wet breach]

then you need to install a webserver

[icy beacon]

I was like "How can I install an SSL certificate on a domain of your vps"

[quiet ice]

A webserver is something that runs on port 80/8080

[icy beacon]

They were like "go install it"

[spare prism]

my custom events doesn't get called

[icy beacon]

Like bitch yeah thanks for the help

[icy beacon]

I do have a REST API running on port 8080

[wet breach]

oh so they gave you the answer and you just ignored it >>

[icy beacon]

"Install it" is not an answer to "how to intsall it"

[wet breach]

you don't really install certificates per-say, you just tell the various things that need certs where the certs are located to use

literally anything that can use SSL or HTTPs

[quiet ice]

But nothing like apache's httpd, lighttpd or anything else

[icy beacon]

I doubt it

1 sec

They aren't intsalled

[quiet ice]

Then why do you want SSL?

[icy beacon]

For my REST API to be able to use HTTPS

Am I understanding what I'm doing? Again no

[quiet ice]

Then point your rest API to those certs

[icy beacon]

That's why I've come here. trying to comprehend this

[icy beacon]

It.. was that simple?

[quiet ice]

Ye?

[wet breach]

it was never difficult to begin with?

[icy beacon]

I'll reiterate that I have 0 understanding of ssl, certificates, and other shit. I thought it was wired to the domain itself in some way

[quiet ice]

Alternatively proxy the REST API with something like httpd or lighttpd and install the certs for httpd or lighttpd

[icy beacon]

I'll take a look at the docs of ktor now

[wet breach]

well it is tied to the domain in a way yes

that is what the pem files are for

the pem files outlines information in regards to the cert

then it provides the cert

[quiet ice]

(there are more options out there, but I use those two as an example that I can think from the top of my head)

[icy beacon]

Not exactly what I mean, my initial understanding of how SSL would work is that the provider of the domain would somehow attach the SSL certificates to the domain. Very scuffed but now I think it is somewhat more clear

Ty for the help and helping me clear my misconceptions

I'll scout the ktor docs

[quiet ice]

The SSL certs are pretty much just a public/private key pair signed by a CA

At least that is how I understand it

[shadow night]

aren't SSL certs also somewhat client sided? Like, I could make my own SSL cert, the only limit is that most browsers don't know of it so they just won't accept it as a secure connection

[wet breach]

https://www.cloudns.net/wiki/article/378/

technically you could use DNS to hold certs

however, it won't work for https though as that must be provided by the webserver because it needs the fullchain pem file

the fullchain is how a visitor can verify your certificate is legitimate because it can follow the chain to verify

[inner mulch]

if there is an object held in memory, and I hold on to the same object in another class as well, does the object exist twice now, or do both reference the same one that existed in the first place?

[shadow night]

well, depends

[inner mulch]

i save the object in the other class, not with a getter of where it was, i save it in the constructor, so its probably a second instance?

[shadow night]

uhh what?

if you have made it in one class and passed it through the constructor or another method into another class, then it's the same object. If you have specifically recreated (copied) the class, then you will have two identical classes

[inner mulch]

okay, so in the first case that you mentioned, if i now change one in one or the other class, do both receiver the changes, as they are supposed to be the same object?

[minor junco]

They reference the same, if I understood your question right

[inner mulch]

okay

[minor junco]

new Object () allocates a consecutive amount of memory in the heap, which represents the data (attributes) of that object. The returned value is just the memory address (pointer) to that object referenced in memory. If you share the same pointer, the memory is still the same place

[inner mulch]

okay nice

i was worried I'd be using double the memory

if i refer to the "same" object twice

and it seems like it is really the same

[minor junco]

Thats pass by reference and pass by value are different. Java is pass by reference for non primitive data types, and pass by value for primitives. So if you pass a primitive, such as an int, it's copied, since it's a different stack frame in memory, that is "allocated"

[inner mulch]

oh thats good to know

[slender elbow]

java is all pass by value

[minor junco]

Strictly speaking, yes

[inner mulch]

so you kinda lied?

or what does this now mean?

[slender elbow]

it means you don't have to worry about it

when you pass a List around, unless explicitly done, the list is not copied as a whole

it is "shared"

[inner mulch]

ok

[slender elbow]

for example, if you add an element to the list in one class, and the same list was passed to another class, since it's the same list then the other class will also see the new element

but it's a single list

[inner mulch]

okay

[eternal oxide]

Did you shade Vault into your plugin by mistake?

[spare prism]

any help pls #1205131013613948939

[upper hazel]

Is there a way to bypass the restrictions on the form of a final value in a yadda expression?
i try create confortable argument checker

[eternal oxide]

final int toDisplay = hourFrom;

[upper hazel]

this not confortable

[eternal oxide]

just make hourFrom final as you are not re-assining it

[small current]

no its compileOnly

[eternal oxide]

What is the import for your Economy.class?

Do you even have an Economy plugin?

[tender shard]

why are you printing "Vault service not found" when you're clearly already interacting with Vault successfully?

you should rather print "Economy provider not found"

[tender shard]

you don't have any economy plugin installed

[icy beacon]

i am going to go crazy

[rough ibex]

Rats? I was crazy once

[icy beacon]

i;'ve finally configured my rest api to run on an ssl certificate that i generated with let's encrypt and spent way too long turning into a jks keystore, launched it on the vps and it launched over https, then i test how it runs and it fucking errors with invalid certificate

im going to give up on life

[icy beacon]

rubber room

[icy beacon]

i have no fucking idea how to debug this shit and the only idea i have is to regen the certificate again again again

[rough ibex]

What errors specifically?

[icy beacon]

netty

if that gives you any intel

[rough ibex]

Well, that's a big library.

[icy beacon]

no shit

what did you expect to hear

had i seen my lines of code in the stacktrace i'd at least have a general idea of what might be wrong

[rough ibex]

Well, you do get a stacktrace

May I see it

[icy beacon]

i mean sure

1 sec

?paste

[undone axle]

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

[icy beacon]

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

it's omst likely because i have misconfigured something

[twin venture]

Hi , been a while .. trying to save a location [world name , x , y , z ] into .json settings file

[tender shard]

I usually just create a wrapper class that only has the information I need

public class SimpleLocation {
  private String world;
  private double x, y, z;

  public SimpleLocation(String world, double x, double y, double z) {
    this.world = world;
    // ...
  }

  public static SimpleLocation fromLocation(Location loc) {
    return new SimpleLocation(loc.getWorld().getName(), loc.getX(), loc.getY(), loc.getZ());
  }
}

then I throw the SimpleLocation into gson

alternatively you can create a custom TypeAdapter

[icy beacon]

do you have any idea what's going on or should i just go regen

[rough ibex]

Well, it seems youre trying to use an HTTP response as a SSL/TLS record

[icy beacon]

yes googling the error mentiioned there miht be plaintex t or some shit

[tender shard]

why even bother with https? just make your API run only http and then use a reverse proxy

[icy beacon]

what do i do with that info

[icy beacon]

because ktor supports ssl so why not

do you reckon it'd be easier

[rough ibex]

HTTPS also adds a bit of encryption overhead

although thats a bit of a microoptimization

[tender shard]

reverse proxy would be much easier. your application doesn't have to care about https at all then

[icy beacon]

ok my second question is what is a reverse proxy or more specifically how can i set it up

[quaint mantle]

Hi , how to set permission in command sender ?

[rough ibex]

Test for or set?

ensure you know what you wanna do

do you want the command to test for the sender's permission

[tender shard]

1. Make your API run only on localhost (HTTP)
2. In your webserver, create a reverse proxy config for the vhost - it accepts HTTPS requests from anywhere, redirects it to http://localhost:12345 (your API), and returns the results through HTTPS again

<VirtualHost *:443>
  ServerName myapi.mydomain.com

  ProxyPass / http://127.0.0.1:12345/
  ProxyPassReverse / http://127.0.0.1:12345/

  # Configure SSL certificate here like you'd always do on your webserver
</VirtualHost>

[icy beacon]

i have to spin up a webserver 😭

like you'd always do
more like for the fisrt timem

[rough ibex]

it isnt very hard to do

you're running locally

and it's good exposure into networking

[tender shard]

well for apache, HTTPS is as easy as giving it the path to your certificate

        SSLCertificateFile /etc/letsencrypt/live/jeff-media.com/fullchain.pem
        SSLCertificateKeyFile /etc/letsencrypt/live/jeff-media.com/privkey.pem

[icy beacon]

i mso fucking tiredof this bullshit with ssl i'm going to have ptsd

i'll figure it out tomorrow

thanks for the lead alex

[twin venture]

i used this :
but it throw errors

[rough ibex]

and see https://nginx.org/en/docs/http/configuring_https_servers.html for nginx

if you want to use nginx instead of apache

[icy beacon]

i known't the difference

[tender shard]

location is null

[icy beacon]

but i guess i will be enlightened tomorrow

[icy beacon]

holy shit an actual type adapter

i use jsondeserializer/jsonserializer imo much easier

abstracts a bit of stuff out

[twin venture]

should i do new Location ... ?

[tender shard]

no, you should not pass null into your write method

[rough ibex]

the problem is that when you ask if (location.getWorld()) , location itself might be null, so null.getWorld() is an error.

[tender shard]

btw you can't just write beginObject() and then return without having written endObject()

[twin venture]

i got it working :p

[tender shard]

the issue with that though is that you will never get a normal location again if you just register your type adapter globally

[twin venture]

i see

its only 1 location

[tender shard]

that's why I'd just create a separate data class for SimpleLocation, that just has 4 fields; name, x,y,z

then gson can also handle it automatically and you dont even need a type adapter

[orchid brook]

I have this config:

reset:
  # Can be daily / weekly / monthly
  frequency: daily
  reset-hour: 23:59

Is it better to use scheduleAtFixedRate() or runTaskTimer() with a 20 tick repeatDelay ?

[ivory sleet]

runTaskTimer imo

I assume if you use scheduleAtFixedRate, you mean ScheduledExecutorService, which on its own is fine, but first of all, you’re doing this in ticks (according to what u seem to be using) so BukkitScheduler is a more intrinsically intuitive choice, additionally whenever you carry a ScheduledExecutorService you most likely want to carry a dispatcher/execution ExecutorService as well to not put too much load on the ScheduledExecutorService, this can increase overhead due to underhood thread scheduling etc

[tender shard]

I would probably just use cron-utils https://github.com/jmrozanec/cron-utils

[ivory sleet]

That’s only for parsing, no?

[orchid brook]

and if i remove the reset-hour configuration, is it more easy to do right ?

[fringe spruce]

hi guys! how can i set in a gui a custom head from the minecraft heads website

[ivory sleet]

I assume you wanna support routines and exact dates? (Dates= run on a specific time and date) (Routines= run every week/day/month/interval at a specific time)

[fringe spruce]

is there someone who can help me?

[ivory sleet]

Which website exactly? And are you coding this?

[fringe spruce]

do you know the website from which you can give you custom heads in game

https://minecraft-heads.com/

[tender shard]

IIRC it's able to give one a date object and then one could just use a TimerTask + Timer?

[ivory sleet]

Ah, well TimerTask + Timer kinda sucks

I havent ever used cron so I wouldnt know

[tender shard]

hm no clue then 🥲

[fringe spruce]

i guess there is an api but idkj how to use that

[ivory sleet]

I assume its some sort of rest api

[fringe spruce]

anyway,can i insert custom heads in a created inventory?

[river oracle]

Inventory#setItem

[fringe spruce]

but the problem is that i need to create the itemstack

[river oracle]

SkullMeta

[orchid brook]

Alright i got it i think

private void scheduleResetTask() {
        long initialDelay = calculateInitialDelay();

        Bukkit.getScheduler().runTaskTimer(this, () -> {
            // TODO
        }, initialDelay, calculateRepeatDelay());
    }

    private long calculateInitialDelay() {
        LocalDateTime now = LocalDateTime.now();
        LocalDateTime nextReset = LocalDateTime.of(now.toLocalDate(), resetTime);

        if (now.isAfter(nextReset)) {
            switch (resetType.toLowerCase()) {
                case "daily":
                    nextReset = nextReset.plusDays(1);
                    break;
                case "weekly":
                    nextReset = nextReset.plusWeeks(1);
                    break;
                case "monthly":
                    nextReset = nextReset.plusMonths(1);
                    break;
            }
        }

        return ChronoUnit.MILLIS.between(now, nextReset.atZone(ZoneId.systemDefault()));
    }

    private long calculateRepeatDelay() {
        switch (resetType.toLowerCase()) {
            case "daily":
                return TimeUnit.DAYS.toMillis(1);
            case "weekly":
                return TimeUnit.DAYS.toMillis(7);
            case "monthly":
                return TimeUnit.DAYS.toMillis(30); 
            default:
                return TimeUnit.HOURS.toMillis(24);
        }
    }

I hope this will not use to much resources to my server.

[ivory sleet]

Prob not

I mean your implementation looks a bit under engineered

but its fine

[orchid brook]

oh realy ? hmm

[ivory sleet]

well

[fringe spruce]

Yes, how can I set the head to be like the custom head

[ivory sleet]

Error handling, and tps loss, and availability and persistence may not be fully supported, but I think you don’t need to care about all that

[river oracle]

Provide it a player profile with the skin url

Bukkit#createPlayerProfile

?jd-s

[undone axle]

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

[river oracle]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/profile/PlayerProfile.html

Btw UUID doesn't matter

Just use UUID.randomUUID

[fringe spruce]

i want a head on a gui to look like a custom head

how can i do that without the uuid

[hasty oyster]

I'm trying to make items non-stackable, is there a good way to do that, my first thought was just giving it a random uuid tag, but I'm not sure how to do that, is there a better way?

[hazy parrot]

random tag seems good enough for me

[orchid brook]

I see and what is persistence ?

[ivory sleet]

If the app is closed and it starts again (such as a reboot), then no loss of tasks that have been executed or were going to be executed etc

[hasty oyster]

Is there somewhere which does this simply that I can just use? :)

[hazy parrot]

?pdc

[undone axle]

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

[hasty oyster]

Works great, thanks!

[orchid brook]

ok good i have add a tps checker and delay the task if tps are not good 🙂

[ivory sleet]

yeah, well at least u're using runTaskTimer() and not scheduleAtFixedRate() which would impose additional care regarding synchronization, visibility etc

hello. can we add player leash to player with NMS ?

I want both players to withdraw while they are connected to each other with the lead item.

[chrome beacon]

Yes

[chrome beacon]

No idea what you mean by this

[trim quest]

i mean there is event like PlayerToEntityLeadEvent

can we implement PlayerToPlayerLeadEvent with NMS

[chrome beacon]

You can

[trim quest]

after changed HumanEntity or Player interfaces

i want to add bidirectional leashing

i can but how i still wonder

if there is good resource can you link me

[chrome beacon]

I don't see why you need to

You don't need to use NMS?

also when you're working with NMS you're mostly on your own

the best documentation is the code itself

[lethal knoll]

Hi, what is the new supported method to parse a string to a potion effect type?

it's all deprecated

[pseudo hazel]

which one is deprecated?

[lethal knoll]

static methods, getByKey, getByName, getById

[chrome beacon]

Read the deprecation note

[pseudo hazel]

it says to use Register.get(NameSpacedKey) instead

right in the docs

[chrome beacon]

^^

[pseudo hazel]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/potion/PotionEffectType.html

[lethal knoll]

yeah, trying that

Might be me but I don't see how to use this method

[chrome beacon]

Registry.EFFECT.get(key)

[lethal knoll]

ah ait

wait

yes I see

thnx

I am still not getting what I need here, I just need to fetch a PotionEffectType, not a potion, and also not a list of effects from a potion

Goal is that I can store the type of the effect in a config, and use it afterwards to change it back to an effect

[pseudo hazel]

so what step are you still missing

[lethal knoll]

I'm not sure, I can't believe I have to get a potion first to get a PotionEffectType

Especially not because there is still a depcrated version to get it by the key

[pseudo hazel]

didnt you already have the string?

[lethal knoll]

Yes I do, the string I have

I just need to get the PotionEffectType

not the potion

okay nevermind

I was stupid -_-

I'm just not remaining up to date enough with the API's

Thank you both

[quiet ice]

Does Hashmap have decent iteration performance or is it more or less "required" to have it be a LinkedHashMap if you forsee the possibility of iteration?

I'm expecting up to about 200-ish elements for reference - but more are not impossible

[pseudo hazel]

no thats still fine

idk what you consider decent

[quiet ice]

Well, anything that wouldn't kill performance a-la #getItemMeta

[ivory sleet]

I mean yea, LinkedHashMap carries what u seem to be looking for in ur latter question

[rotund ravine]

Probably fine unsorted

[ivory sleet]

However, HashMap is fine

And there is less overhead iterating over a HM iirc

Tho its negligible unless u fly to the moon

[rotund ravine]

Thanks. What about my Mars java space software?

[quiet ice]

I was asking because LinkedList vs ArrayList is not much of a performance difference (at least on modern computers)

[ivory sleet]

Oh that one? Well delegate it to… Geol!

[rotund ravine]

Not really comparable to a HashMap and LinkedHashMap

[quiet ice]

I'm not going to read through the hashmap impl

[quiet ice]

Sorry, but I am not the person to use eclipse mars in the year of 2024. Though I do know a few people that do it anyways

[ivory sleet]

But if we’re speaking at max n = 200 I don’t think you need to care about overhead that much between Linked vs non-Linked

for the average jvm

[pliant topaz]

I was just wondering why these two objects aren't the same? (The rightclicked item is just Dice.get() in the furthest right hotbar slot, but it still prints 'no')

            System.out.println("Rightlicked dice");
            DiceMechanic.rollDice(player);
        } else {
            System.out.println("no");
        }```
Anyone knows what could be the problem? (I also compared the ItemStack object in console and they were the same if I didn't overlook something)

[orchid gazelle]

try .equals

instead of == comparison

[rotund ravine]

Compare with equals or isSimilar

[pliant topaz]

I'll try that thx

Okay, it works, but I've got another error ;-;
I used Bukkit.getScheduler().wait(100) to create a small delay but the thread isn't owner, so yeaaaa. Is there anything else I could try (that i can put right into my code without enclosing it or something)?

[inner mulch]

Is there any way to have two constructors with the same parameters, that do different things tho?

[rough ibex]

How are you going to tell them apart

do you want to use a factory

[ivory sleet]

thats not how u use the scheduler

[quiet ice]

Schedule a task which is delayed instead

[pliant topaz]

So like I did it here?

                    },2);```

can I do these empty?

[quiet ice]

You cannot use Thread.sleep() or similar in a minecraft setting - (exception is the synchronized keyword, but that should only be used in relation to thread safety and nothing else)

[quiet ice]

Yes, but inside the brackets (also called lambda) you put in the logic that should be delayed

[pliant topaz]

well, there's nothing that really has to be delayed, that's the thing. I need code to be executed instantly, then a 2 tick delay

[quiet ice]

For example if you wish to call the method this.runDelayed() every 2 ticks you do Bukkit.getScheduler().scheduleSyncDelayedTask(Catan.plugin, () -> {this.runDelayed();}, 2); or (short form, but is likely to be more confusing for you) Bukkit.getScheduler().scheduleSyncDelayedTask(Catan.plugin, this::runDelayed, 2);

[quiet ice]

Then what do you need the delay for exactly?

[pliant topaz]

I'm making a dice, and I want it to 'roll' every 2 ticks

after 2 seconds it's finished and gives the final result

[quiet ice]

Repeatedly every 2 ticks or just a single delay of two ticks?

[pliant topaz]

just a single delay

[quiet ice]

Then you put anything that needs to be executed after two ticks inside your lambda

[pliant topaz]

Okay, ty

[quiet ice]

Just beware that the lambda will only execute after two ticks while the rest of your method should (ideally speaking) be instantly finished - so two ticks prior your lambda

[orchid gazelle]

Does anybody here know how I can check if my Location is colliding with any block? Needs to be really fast from a processing time pov

          if(material != Material.AIR && material != Material.WATER && material != Material.LAVA) {
              return new RayCastResult(RCType.block, current, null, null);
                  }
          }``` got this shit, needs to be about 100-1000x faster tho lmao

running this for every 0.0625 blocks in my ray

and is also inaccurate

[quiet ice]

What is this for? I suppose bukkit's raytracing is too slow for your purposes?

Because depending on the usecase you might be able to do dumb hacks instead of properly raytracing

[orchid gazelle]

it cannot do everything I want to do

[quiet ice]

The trick when it comes to doing things fast is to do as little as possible

[orchid gazelle]

yeah

[orchid gazelle]

well, but how do I make this little lmao?

[inner mulch]

how is it that targetplayer is already defined in scope, even tho i call break?

[quiet ice]

Just add a {}

[inner mulch]

okay thank

s

[quiet ice]

This plainly has to do with the fact that java local variables are valid until the corresponding closing bracket (}), even if it would be impossible to use these vars otherwise (which is the case in switch statements)

[celest notch]

I currently have an auction house on my rpg server but it is really inconvinient for buying large amounts of items as it is limited to a stack per auction, how would i code something similar to hypixel's bazaar maybe?

[quiet ice]

Well, I cannot tell given that I have next to no information.

The code you provided cannot be improved further though, at least not as-is. (I guess you could make use of Material.ordinal() but that is too negligible of an improvement, if it even is an improvement. And even then it is too brittle)

The libGDX guys are quite fond of object pooling so I suppose you could use that, but it won't make much of a difference on modern hardware with modern software.
You could also use NMS instead of the bukkit equivalent (however I suppose that is not what you want) and perhaps even cache the world (or if using NMS - chunk section? I haven't used any NMS though, if you cannot tell already so take this with a grain of salt) if the code is called in a loop

I'd just use spark and work on eliminating or reimplementing the hot code in NMS if this was really required

Depending on the usecase you can use stupid amounts of caching too (especially if you expect to do basically the same action multiple times)

[hazy parrot]

why not just get player before switch

[shadow gazelle]

Having two constructors of the same class with the same parameters is not possible

[inner mulch]

because not all cases get a player

[slender elbow]

how would you specify which one to invoke

[shadow gazelle]

Magic

[slender elbow]

cmarco with the real answers here

[spare mason]

anyone knows any tool to visualize a group of block entities?

[worldly ingot]

Constructor(A a, B b, C c) {}
Constructor(A a, B b, C c) {}

new Constructor(a, b, c)[0]; // Call the first one

😎

[inner mulch]

which language is this?

[worldly ingot]

Some severely fucked up Java that doesn't exist

[inner mulch]

okay

[worldly ingot]

Generally speaking your constructor shouldn't have any side effects - it should affect pretty much only the object instance itself. If still you need two different ways to instantiate an object, pass a boolean to the constructor

[inner mulch]

what does side effects mean?

oh

it shouldnt do something to other objects?

[worldly ingot]

Correct

More of a general thing to keep in mind than a strict rule though

There will always be exceptions to said rule lol

[inner mulch]

what if my constructor does that :(? is this a bad design?

[worldly ingot]

Depends on your object, depends on what it's doing ¯_(ツ)_/¯

[inner mulch]

im creating it, and save it instantly to the place it belongs once created

i save it in memory

[spare mason]

hi, i am trying to use display blocks but it uses matrix, I haven't seen anything about a matrix even on school, there's any good tutorial to start learning about that? I have been browsing for some hours but most of it was of matrix of 2x3 but display blocks need a matrix of 4x4 and a value from -1 to 1. I would really appreciate if someone send a link to learn about this

[ivory sleet]

its actually sometimes considered an antipattern in terms of concurrency because u may without intention publish this reference outside of its scope before the object has finished its construction

[worldly ingot]

Spigot abstracts away a lot of the matrix math for you. You can use setTransformation() with a Transformation object which lets you specify individual components

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/util/Transformation.html

[spare mason]

What does translation value does on that method?

[worldly ingot]

Translation is movement on the x, y, and z axis

[spare mason]

And left and right rotation? Why the 2 of them are needed

[worldly ingot]

Right rotation is applied first, then scale, then left rotation

You can just use right rotation if you'd like and set the left rotation to a unit quaternion (new Quaternionf())

[grave vigil]

Does a bukkitrunnable scheduler reset on server restarts? I want to have a timer that activates once every month.

[worldly ingot]

Yes. It's only valid for the current runtime

You'll have to schedule a task that runs every hour or something that checks the current day

[grave vigil]

thanks

[spare mason]

Ohhhh, thanks choco, I really had no idea how this worked

[quaint mantle]

LMAO

[manic delta]

Someone who knows about reflection, I have a plugin that I made in 1.20 and I want to make it compatible with 1.13+, the plugin is already finished but I was looking for reflection and the truth is I didn't understand anything lol, so I would like someone to help me understand how to do it, this is the repository, obviously I will give credits and contributions to anyone who can help with this problem
https://github.com/system32developer/Kit-Renamer

[quaint mantle]

@minor otter

is this a ghost item or real item

[remote swallow]

You dont use nms so lower the spigot dependency version in pom and api-version in plugin.yml

[manic delta]

i need to use spigot 1.13 as base then?

[lost matrix]

Cancelling the InventoryClickEvent will completely prevent items from being moved between inventories.
Does this only occur in creative mode?

[quaint mantle]

why does the moderator rank have the admin prefixes even though the one
own has this is my config

useChatFormat: true
useColorTranslate: true
chatFormat: '%chatPrefix%%playerName%&8: &7%message%'
autoUpdate: true
Prefixes:

• owner;&4Owner &7» &4;&4Owner &7- &4
• 'default;&7Player&7: ;&7Player&7 ➜ '
• 'Supporter;&2Supporter&7: ;&2Supporter&7 ➜ '
• 'Admin;&eAdmin&7: ;&eAdminstrator&7 ➜ '
• 'Moderartor;&aModerartor&7: ;&aModerartor&7 ➜ '

in the lucktab plugin

[lost matrix]

#help-server

[raw sky]

is it beneficial to any way to use a lib like skedule or mccoroutine over the bukkit scheduler?

i have to use some suspend methods to download files and make http requests

[quaint mantle]

Creative mode inventories are like broken

[lost matrix]

I would not use a library for some simple IO

[quaint mantle]

HttpRequests you can use the httpclient and pair it up with an executor service

[wild roost]

how do I open an inventory which is created by command and then should be opened in the other class?

I cant make Inventory public or smth, so idk how

[glad prawn]

use something to contain it?

[manic delta]

Wym exactly

[wild roost]

so, im tryin to make a simple item-based backpack, when player executes command /getbag, he gets an item, which when u right click on it opens a small inventory

[manic delta]

You can save the inventory for the player

[wild roost]

to the variable?

[manic delta]

Or you can save the inventory contents on the item, using nbt

[manic delta]

You could save it in a hashmap for example

[wild roost]

so, ill try, thnx

[manic delta]

Good luck

[wild roost]

and one more thing: when i set inventory's owner as player, can I get an inventory using player.getInventory?
code:
Inventory bagInv = Bukkit.createInventory(player, 9 "Small Bag")

[eternal oxide]

no

[wild roost]

🥲

[upper hazel]

Is buildTools needed to add NMS to a project?

and is it necessary to add all subversions from the main version for the plugin to work from 1.17.x to 1.20.1?

[rotund ravine]

Skedule is a nice QOL

[eternal oxide]

First answer, yes. Second, is it depends

[shadow night]

Why does that sound like a scheduler for skript lol

[upper hazel]

but how can I create a dependency if the location where the server jar comes from is not specified?

[eternal oxide]

Maven modules

[upper hazel]

then why i need use buildTools for this

[eternal oxide]

pretty sure alex will have something on his site about multi module by now

buildtools gives you the source

?nms

[undone axle]

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

[eternal oxide]

https://blog.jeff-media.com/maven-multi-module-setup-for-supporting-different-nms-versions/

[upper hazel]

why i need this source if dapandancy exists in maven repository

[eternal oxide]

it doesn;t

NMS is Mojang code and not on any repo

[upper hazel]

but how then intelji can know where source exists???

[rotund ravine]

Local repo 👌🏻

[eternal oxide]

NMS = net.minecraft.server, or shoudl really be called native minecraft code, as it now also contains other packages like org.mojang

[eternal oxide]

Buildtools puts it in your local repo, as Jan said

[upper hazel]

For all dependencies located locally on the PC, you have to specify the location from where they are located, don't you?

[upper hazel]

oh

[eternal oxide]

no

its a local maven repository

generally it's always searched first

[upper hazel]

So intelji is looking for dependencies in all folders?

like antivirus??

[eternal oxide]

no

if you specify net.minecraft.server, it looks in your net\minecraft\server folder in your local repo

local repo is usually somewhere like C:\users\name\appdata\.m2 or something like

[upper hazel]

That's the thing, I didn't specify anything.

[eternal oxide]

you don;t specify a path, it's your imports

Just go read alexs' page

You specify the dependency just like all

spigot not spigot-api

[native ruin]

I have yet to have the courage to learn nms

[rotund ravine]

There is nothing “to learn”

[eternal oxide]

don;t. Its a last resort

[upper hazel]

So it turns out that BooildTools automatically loads dependencies into the local repository ?

[eternal oxide]

yes

Buildtools should already be the way you are getting your Spigot server jar

[rotund ravine]

You won’t wrap ur head around all of it. You might be able to wrap ur head around the current issue ur facing and then it all changes mext version and u start again. All you gotta learn is to navigate and figure shitz out

[native ruin]

So being a 1.8 dev has atleast 1 advantage

[shadow night]

Being a 1.8 dev has too many disadvantages to look at advantages lol

[native ruin]

if it pays it pays

[tropic saddle]

its same shit, okaeri tasker implements bukkit scheduler xD

dude okaeri tasker is literally bukkit scheduler but simplified

[grim hound]

what the fuq

This mfo acts like spamming the message will help in any way

[tender shard]

how are you creating your skulls?

[grim hound]

reflection

cuz multiversion

[tender shard]

why?

[grim hound]

and it works

[tender shard]

as you can see, it works subpar

on 1.18.1+ you must use rather use the API

[quaint mantle]

Spigot have api for skulls

[tender shard]

fallback to reflection only for extremely outdated versions

like 1.17

[grim hound]

only in the very newest

[tender shard]

no, since 1.18

[quaint mantle]

Bruh I thought it existed since 1.12.x

[grim hound]

so these ffers

[tender shard]

API to get an offline player's skull exists since forever

[grim hound]

didn

't have any api until now

[tender shard]

but API to get a specific "base64" skull is 1.18+

[grim hound]

and when people found a solution they just said "nah, we adding it now and telling you all that you're doing it wrong"

[tender shard]

the way you've been using reflection has been wrong all the time

you will have to set all fields properly and then the warning won't appear

but why not just use the API on versions where it's available?

[grim hound]

I just found it on the web

[grim hound]

cuz

it

works

only the texture is necessary

for me

so why spam messages?

[tender shard]

well you have two options, either

1. You use the intended way, or
2. you keep using your outdated way, but then you gotta stop complaining about that message

https://blog.jeff-media.com/creating-custom-heads-in-spigot-1-18-1/

[grim hound]

can you at least tell me how

oh, thanks

[tender shard]

You can do sth like this:

[grim hound]

wait, it has to be a web url?

what if I already have just the skull's value?

isn'

t that what's necessary?

[tender shard]

if(isMc1_18orNewer()) {
  // Do it like in the blog post
} else {
  // Use your old reflection way
}

public static boolean isMc1_18orNewer()) {
  try { Class.forName("org.bukkit.profile.PlayerProfile"); return true; }
  catch (ReflectiveOperionException e) { return false; }
}

[tender shard]

it's explained in the blog post

just keep reading

[tropic saddle]

its same while making fake players for tablist?

[tender shard]

idk I never made fake players

[ivory sleet]

You can probably just spoof some packets

Ofc might need to switch up depending on version

[grim hound]

player info packets

[ivory sleet]

Yep

[tropic saddle]

whaat im asking about setting custom heads on gameprofile

/ serverplayer

[grim hound]

bruh

[tender shard]

it's not deprecated

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/profile/PlayerProfile.html

you must be using some other API besides spigot

[grim hound]

paper

but paper is really great at making things harder

for no reason

[valid burrow]

not for no reason lol

[tender shard]

you can still use PlayerProfile, even though paper claims it's deprecated. As you see in the spigot docs, it is not deprecated in spigot

[valid burrow]

paper has its reasons

[grim hound]

no

it changes cosmetic things

[valid burrow]

every seconds method is depricated in paper. Best to just ignore it

[grim hound]

and makes them worse

for no reason

[drowsy helm]

paper deprecations are more of a suggestion

[valid burrow]

like what

[grim hound]

player quit console message

[tropic saddle]

paper uses kyori instead of normal strings

[grim hound]

console plugin logging

[tender shard]

Just use the Spigot API if you want your stuff to be compatible with spigot.

For paper-specific features or adventure, you can still shade adventure manually, and use PaperLib

[tropic saddle]

i personally thing that kyorii components are easier to use than basecomponents

use purpur api, paper is legacy :tf:

[tender shard]

if you use paper-api, then you can expect your plugins to not work on spigot anymore

[valid burrow]

who gives a shit about that

[tender shard]

yeah

[valid burrow]

true

[tender shard]

i also use adventure / minimessage for everything but I still use Spigot API instead of paper api

[tropic saddle]

paperweight is the best option if u want to use nms btw

[upper hazel]

plugin will work with this maven? https://paste.md-5.net/

[tender shard]

i don't think so, it again forces you to use paper-api which might lead to you accidentally using paper-only features

[tropic saddle]

?

[tender shard]

that's an empty paste

[upper hazel]

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

[tropic saddle]

u can use buildtools but it forces u to use maven again

[valid burrow]

who WANTS to use nms though x) i usually only use it when im forced to

[native ruin]

the awnser would be no then xD

[tender shard]

no, there's a lot of remapping plugins for gradle available

e.g. this https://github.com/patrick-choe/mojang-spigot-remapper

[tropic saddle]

use multi modules dude for each version

[tender shard]

no, this will not work

all those spigot versions provide the same classes, hence you'll always only see them from one version

[tropic saddle]

idk, i found paperweight working so used it it also gives u ability to run test server in a second

[tender shard]

@upper hazel https://blog.jeff-media.com/maven-multi-module-setup-for-supporting-different-nms-versions/ This is the proper way to use different NMS versions

[tender shard]

yeah it would be a great plugin if it wouldn't automatically add paper-api to the classpath

[tropic saddle]

u can use purpur api 😉

[upper hazel]

i shold create should I create multiple plugins in 1?

[tender shard]

people who care about being compatible with spigot will not use anything except spigot-api :p

[tender shard]

no, you'll only have different modules for NMS-specific code

[tropic saddle]

who uses clean spigot server jar

[tender shard]

over 20% of people

[tropic saddle]

non sense

[tender shard]

I also use spigot

[valid burrow]

many actually

[tropic saddle]

for what reason u wont use purpur for example

[tender shard]

and there's another reason to support spigot: paper-only plugins aren't allowed to be uploaded on spigotmc

[tender shard]

because

1. it breaks vanilla mechanics
   and
2. doesn't add anything that'd be useful to me

so why would I use sth that only makes my life harder

I don't have 385 players, I don't profit from purpur

I only have one player

[valid burrow]

why so specific lmao

[tropic saddle]

purpur makes ur server more optimized i guess

[eternal oxide]

buggier is the word

[tropic saddle]

has some things in api that also makes ur life easier

[ivory sleet]

What exactly?

Ik it had like one new event or sth

Wouldn’t say that was lifesaving in any meaningful way

[tender shard]

well you're free to use it ofc. I won't, I want to be able to upload my stuff to spigotmc

[tropic saddle]

is it worth selling stuff on spigotmc?

oh i just saw ur profile, no questions

[valid burrow]

well if you make things that are highly configurable and have many use cases then i think you can make a pretty penny with em

but that’s complicated as all of that stuff already exists

its easier to make custom plugins imo

[tropic saddle]

ik, got skills but hard to come up with an idea

[ivory sleet]

I mean if you have a spigot compatible plugin you want to sell, its probably not a useless idea to just put it on spigotmc, but I’d assume u have it on other platforms ntl

[tropic saddle]

i think that creating minigames server and selling it would be worth more to put time in

[ivory sleet]

Eh, well, if you really wanna earn cash I don’t think server sided mc dev is the hustle for you

[tender shard]

scrooge mcduck made his first million with 1.8 plugins

is -1 allowed as custom model data?

[ivory sleet]

yea, well I don’t believe your average purpor enjoyer will pull a scrooge mcduck, but perhaps

[ivory sleet]

I believe so

[tender shard]

oh no that's annoying

[ivory sleet]

I’m actually unsure

[native ruin]

let's fuck around and find out

[ivory sleet]

💯

[tender shard]

if -1 is allowed then my blackliast is broken 🥲

[ivory sleet]

lol why?

[tender shard]

because I'm using -1 to identify items without custom model data

[ivory sleet]

Well items w/o CMD has a null value, no?

[grim hound]

I didn't find it

how I could set the value directly

"eyJ0ZXh0dXJlcyI6eyJTS0lOIjp7InVybCI6Imh0dHA6Ly90ZXh0dXJlcy5taW5lY3JhZnQubmV0L3RleHR1cmUvOThiNWU5ZDVhZmFjMTgzZjFmNTcwYzFiNmVmNTE1NmMxMjFjMWVmYmQ4NTUyN2Q4ZDc5ZDBhZGVlYjY3MjQ4NSJ9fX0"

this is an example of a skull value

it contains the texture within

[sullen marlin]

No it doesn’t, decode it

[tender shard]

no, but my blog post explains how to turn that into a URL

this part

https://blog.jeff-media.com/creating-custom-heads-in-spigot-1-18-1/

[grim hound]

oh

[hushed spindle]

did we change the flash particle recently for some reason

i used to be able to pass a size to the flash particle but now it throws an error when done so

saying the expected data is void

[tender shard]

in which version were you able to pass a size?

[hushed spindle]

like uh, 1.16 or something i dont quite remember

i guess i shouldnt say recently then lol

[tender shard]

can you show some code that worked in 1.16? Because usually the data is a class like BlockData or ItemStack or MaterialData or DustOptions etc

[upper hazel]

hey must be created as a regular module "core" and not through bukkit plugin ?

[tender shard]

wdym?

your "core" module will usually contain the plugin

unless you want to abstract it even further, then you'd have a separate plugin module

if you only want to have multi version NMS, then core/plugin can be one module

[upper hazel]

in the tutorial you create the base of the plugin using the usual method and not through plugin bukkit and then configure everything manually

[tender shard]

no clue what you mean with "usual method" or "through plugin bukkit"

do you mean that I'm not using IJ's "Create Spigot plugin" project wizard?

[upper hazel]

i can create module like this?

core module

[rotund ravine]

Minecraft dev plugin

[upper hazel]

with automatic configuration rather than doing everything manually

[tender shard]

yes but there isn't really any benefit from using that

I mean all it does is to add the maven-shade-plugin which you don't need

but sure, you can use that

[upper hazel]

ok

[upper hazel]

he creates a lot more. The differences between maven and a regular project with the main class are very different

"Main class"

[rotund ravine]

Not that much difference

[tender shard]

doesn't it only create a main class with an empty onDisable and empty onEnable method?

[rotund ravine]

Yeah

[tender shard]

// Plugin startup logic

kek

[rotund ravine]

Plus a package structure

[tender shard]

https://github.com/mfnalex/Spigot-Plugin-Generator > mcdev plugin (at least for spigot) :p

[rotund ravine]

I use a github template for my kotlin plugins

[tender shard]

oh btw that IJ dev plugin will mess up your parent/child project structure

be sure to add the parent section to your core pom if you use the weird MC DEv wizard

[upper hazel]

https://paste.md-5.net/ziyuxeyifo.xml - this all need for maven apache?

[tender shard]

no

[upper hazel]

it is generally needed for the plugin
?

[tender shard]

it would be much easier if you'd just follow the blog post exactly

[rotund ravine]

Gl alex

[tender shard]

for example what even is your question?

whether you can use that as complete pom? no

[tender shard]

D:

[upper hazel]

I was responding to your answer
"I mean all it does is to add the maven-shade-plugin which you don't need"

[tender shard]

you only need the maven-shade-plugin if you want to shade any dependencies. and even if you do, you would want to use a more up-2-date version instead of maven-shade 3.2.4

[upper hazel]

but maven created through bukkit configuration and through the regular one are different

[tender shard]

yes, it includes some useless stuff

as said

[upper hazel]

so i gess i not need this lines for plugin in here? - https://paste.md-5.net/ziyuxeyifo.xml

[tender shard]

you're sending 3 things at once

1. the maven-compiler-plugin - you need that to change the java version. You currently set it to 10, which is pretty weird. You normally either use 8 or 17
2. the shade plugin - as said, only needed when you wanna shade dependencies. You also have set "createDependencyReducedPom" to false, which is very bad. And 3.2.4 is hella outdated
3. resource filtering - usually you want to keep that

and I bet that your MC Dev plugin has not properly added the <parent> section to your pom

[upper hazel]

such lines were created automatically when I created the plugin using "bukkit builder"

I didn't change anything there

but apparently, as I understand it, some people like to create a template for the plugin manually

in any case, I think all these lines are not needed

[tender shard]

Yes, I told you that

[tender shard]

Yes, because then you don't end up with a bloated, broken pom

[tender shard]

exactly, hence I said "the mc dev plugin adds useless stuff to your pom"

and I also bet that the mc dev plugin broke your pom by getting rid of the <parent> section

[native ruin]

Would it be practical to convert pdc into a class to edit it and then push it back in or edit it all one at a time?

[tender shard]

would be so much easier if you simply followed my blog post

[tender shard]

I don't really understand what you mean. Do you have a bunch of PDC tags and want to turn them into an object? Like a custom serializer/deserializer?

[upper hazel]

I understand, I'm just not well versed in the maven system

[tender shard]

that's another reason to just blindly follow the blog post instead of using the mc dev plugin, because then you end up with a different pom and have to understand why things are different and which of those changes are correct and which aren't

[native ruin]

No, I just want to edit the pdc a bunch of times and it would be easier to convert it first in a class so it's easier to code.
because of the many keys idk if that would be efficient

[tender shard]

what exactly do you want to convert to a class?

I don#t really understand what you're trying to do

[native ruin]

map the pdc to a class so i can do var + 1 instead of getpdc().get(new namespacekey(plugin, key),int) + 1

[tender shard]

ofc you could do that, but I don't think it matters. the PDC not much different to a HashMap kept in memory

[native ruin]

so it would just be a waste of resources?

[tender shard]

No, it‘d just be waste of time (premature optimization)

And you‘d have to remember to update the PDC itself

I would just use the PDC directly

[raw sky]

it’s the entire plugin tbf

Bungeecord is just the proxy, im pretty sure you cant interact with spigot stuff in Bungeecord

Yes, spigot can interact with bungee but bungee not with spigot
