[ivory sleet]

what if u set Xmx and Xms

[slender elbow]

[acoustic pendant]

what

[acoustic pendant]

did that already

[slender elbow]

care to share the output of mvn dependency:tree ?

[shy zinc]

Im sorry, where to generate that?

[slender elbow]

this is very weird

in a command line/console/terminal of your choice

standing on the project dir

[sacred mountain]

i mean

[shy zinc]

I will!

[sacred mountain]

it doesnt help you forgot a semicolon

[slender elbow]

it should still show up correctly

[shy zinc]

yeah ahah i know

but it auto optimizing imports

[sacred mountain]

whats ur pom xml look lke

or build gradle

[drowsy helm]

You downloaded 32 bit java instead of 64

[shy zinc]

Emily can i send the tree dm it wont here

[shy zinc]

2 sec

[drowsy helm]

32 bit only supports like 2gb mem

[slender elbow]

sure

[acoustic pendant]

it seems like that lol

[shy zinc]

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

[slender elbow]

hmm

this is odd, spigot is not resolving its transitive deps

[shy zinc]

Im sorry, that means?

[slender elbow]

does it compile fine when you run the package goal?

[shy zinc]

Yeah perfect, ive been developing on this plugin for months now. Its the fkn java 21 fucking it up

btw

idk about if its giving more to the solution but

] The metadata C:\Users\Mathias S\.m2\repository\org\spigotmc\spigot-api\1.20.6-R0.1-SNAPSHOT\maven-metadata-repo.xml is invalid: unexpected markup <!d (position: START_DOCUMENT seen <!d... @1:4) 

i get warnings like these

when compiling

[slender elbow]

oh

yeah that doesn't look good

[shy zinc]

fuck

ahah

it also says similar but with 1.17 and thats very wierd. Havent touched that version

[slender elbow]

can you try running uhh

personally

i'd just go and nuke the C:\Users\Mathias S\.m2\repository\org\spigotmc\spigot-api\1.20.6-R0.1-SNAPSHOT\ directory

then refresh maven from within intellij

[shy zinc]

are you crazy

that sounds risky

[slender elbow]

nah it's fine

[shy zinc]

ahah what

[eternal oxide]

its safe

[slender elbow]

it'll trip maven to redownload it

[shy zinc]

i really trust you on this one

[ivory sleet]

you can trust her

[shy zinc]

okay okay fine chat

ahah

[river oracle]

deleting anything in your .m2/repository is fine and won't cause issues outside of the time it takes to redownload lo

[slender elbow]

maven-metadata-repo.xml, can't say i've seen that file before but i don't use maven so sure

[shy zinc]

its gone for sure now

[shy zinc]

what about that

[sacred mountain]

bro i just got 3 sigsegvs

[slender elbow]

nothing really

nice

[shy zinc]

now nothing in my code should work right

ive just deleted spigot?

[sacred mountain]

🔥

[slender elbow]

did you refresh maven?

[shy zinc]

what is it about your fire dude ahaha

[shy zinc]

ec

2 sec

[slender elbow]

at worst you need to restart intellij to trip it to refresh maven lol

[shy zinc]

is this like sum manipulating my idea or what

btw its still here in here

i refreshed maven

[slender elbow]

it looks like some file was incorrectly downloaded or something so, best shot is to go nuclear and get rid of it for maven to redownload it

[shy zinc]

i cDUDE

OR MISS

ITS FKN WORKING

[slender elbow]

let's goooo

[shy zinc]

MD_5 IS ON

LETS GO

[slender elbow]

[shy zinc]

i fkn love all of you

[drowsy helm]

i love you too matheis

[shy zinc]

thank you so much and for your patient

[slender elbow]

preach

[shy zinc]

like this is actually revolutionary for my development

[slender elbow]

pizza time

[shy zinc]

your lol emily

[sacred mountain]

i have lost several brain cells

someone write me an api to convert an item tooltip to an image

thanks

im gonna do something productive

[shy zinc]

hope youll get same luck as me ;)

[acoustic pendant]

Now when I try to compile with buildtools anything even appears

It doesn't make sense for me

[drowsy helm]

have you tried running it fomr cmd line

[acoustic pendant]

yeah

I believe

[drowsy helm]

and no output on that either?

[acoustic pendant]

wait no

I haven't

[drowsy helm]

give that a try

might just be a ui thing

[shy zinc]

okay, actually havent figured it out 100% yet. my buildtools version of spigot-api doesnt have this net.md_5 would you just recommend me to reinstall the buildtools, like build it over again or any tips?

[river oracle]

it won't

that's intended its a different dependency that is provided transitively

[shy zinc]

Yeah i figured, my mistakes. all seems to work now

[acoustic pendant]

For some reason it is unable to access jarfile

[river oracle]

you need to cd into the correct directory my mans

[acoustic pendant]

it is in the correct directory

[drowsy helm]

run dir

show the output

[acoustic pendant]

Uuh, it says the dir is BuildTools.exe but i'm opening the Git Bash clicking on the folder, not in the app

[river oracle]

you need to downloar the jar to run it from the command line

[drowsy helm]

no i mean in cmd

[river oracle]

he has the exe

[river oracle]

it won't run from the command line

[drowsy helm]

ah yeah

[acoustic pendant]

wdym?

[royal heath]

I think they mean Windows cmd, you need to run the jar

[wet breach]

If you want to run from command line grab the buildtools jar instead

The exe you are supposed to double click

[wet breach]

It technically could be made to launch from command line just fyi. Maybe someone didnt think of it? Lol

[slender elbow]

yeah and that's what happens

i think they mean detecting whether it's being ran on the terminal and doing the regular process without the ui?

[hasty prawn]

@tender shard any chance you merge this and update your repo 🥺 https://github.com/mfnalex/ArmorEquipEvent/pull/5

[alpine swan]

in https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/event/player/PlayerLoginEvent.html, getRealAddress() states that the difference between it and getaddress is that it can't be spoofed

is it talking about being spoofed by the client or by the server?

im just making sure because onlyproxyjoin uses getAddress() and it would be a bit worrying if it could be spoofed by the client

[wet breach]

This.

[fossil wigeon]

I wanted to mess around with packets (viewing/editing incoming/outgoing packets or something along those lines) mostly for the sake of just snooping around and learning a bit, does spigot itself have any "straightforward" way to interact with packets or would I be better off just using something like protocollib?

[stoic tapir]

protocollib dabest

[river oracle]

I'd use PacketEvents

spigot api will never expose a generic packet API

[vast ledge]

?paste

[undone axle]

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

[vast ledge]

Im trying to "hide" the player, im using protocol LIB, and sending the following packet, yet i can still see the player
https://paste.md-5.net/xohicerero.cpp

[eternal oxide]

the API has hidePlayer(Entity)

[vast ledge]

That seemed to have "delay", it would take about 20s and moving around, for the player to actually disappear after hiding them with #hidePlayer()

[eternal oxide]

I've seen no complaints using hidePlayer

[vast ledge]

Ah okay, the destruct packet works, when i run it, but Ig i have to delay it so it doesnt get sent at the same time as the player spawn

[vast ledge]

Not sure, I'm finding the destruct packet more effective, im gna try the delay, and see if it fixes it!

Is there a player "spawn" packet?

[eternal oxide]

yes

[vast ledge]

Would it be NAMED_ENTITY_SPAWN?

[eternal oxide]

I don;t know current

[vast ledge]

What was it?

[eternal oxide]

I couldn;t tell without opening my ide

add player or something

[ivory sleet]

there's a respawn packet

clientbound if thats what u looking for

[vast ledge]

I'm stuck on the old version ,_,

Its probably Play.Server.NAMED_ENTITY_SPAWN

imma just find out :D

It seems to get sent twice ._.

[torn shuttle]

has anyone here ever tried to reverse proxy ssl certs

kinda lost with apache2, got the redirect to work but it's complaining that my cert hostname doesn't match

I'm not even sure it's using the right cert

[slender elbow]

i just let certbot figure it out

[torn shuttle]

oh I kinda figured it out, partly, part of the problem was using wildcard for the ip

[wet breach]

If you still have problems i will need to see to your apache config to see what you have

[torn shuttle]

uh sure

?paste

[undone axle]

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

[torn shuttle]

https://paste.md-5.net/acoyizecuh.apache trying to figure out why magmaguy.com now also redirects to repo.magmaguy.com

I'm sure it's something simple

[wet breach]

You probably didnt setup default host in apache

[torn shuttle]

uh

[wet breach]

However you want to use in vhosts name based and not ip based

[wet breach]

You have two magmaguy.com:443 vhosts

Delete the bottom one

[torn shuttle]

do I just pick one and put everything from the 443 in there?

[wet breach]

You need to add for SSLProxyEngine on
ProxyRequests off

[wet breach]

The top one is already have the cert file specified so i would keep the top one and remove the bottom one

[torn shuttle]

it was two different certs though I am entirely unsure as to whether that was necessary or ever desirable

[wet breach]

<Proxy *> Order deny, allow Allow from all </Proxy>

[wet breach]

There should me a cert file and chain file and full chain

You want to specify cert and full chain

Then for the backend use a self signed cert the front will not see backend cert

Apache is being the man in the middle

So connection terminates at apache and then reencrypts at apache.

[torn shuttle]

ok so progress I guess, teh website doesn't redirect incorrectly anymore

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

so turn off proxy requests

where does that proxy thing go

[wet breach]

All those settings are for the 443 vhost put them at top inside that vhost

[torn shuttle]

(to be clear the stuff after # reposilite is listening on magmaguy.com:50001 is its own conf

well damn it I just realized that the repo redirect was causing the other website on this machine to redirect to the repo

so now I named the config 007-repo.magmaguy.com and now it doesn't redirect correctly

it goes to the default

[wet breach]

SSLProxyEngine On ProxyPreserveHost On ProxyRequests Off <Proxy *> Order deny, allow Allow from all </Proxy> ProxyPass / <url of backend web server> ProxyPassReverse / <url of backend web server>

[torn shuttle]

do I even need more than one conf file?

[wet breach]

Technically no just as long in the master apache conf file vhosts file is specified

But using more then one conf file can help keep things organized as well as not duplicating settings

If more then one thing requires same settings

You can also technically run back end without cert too and just leave the encryption terminating at apache

Just make sure you configure backend to not have https

[torn shuttle]

well

now nothing works

[wet breach]

What do you have for your config now?

[torn shuttle]

also if I try to add that proxy xml thing apache just errors

[wet breach]

The settings i specified need to be inside the vhost bracket for 443

[torn shuttle]

is that not what I did?

[wet breach]

The left one shows it being above and the right doesnt show it inside the brackets lol

[torn shuttle]

uh

proxypass is at the bottom of the right one

I guess maybe I'm passing the wrong one though

[wet breach]

I see that but the proxy tags need to be in there too

[torn shuttle]

<Proxy *>
  Order deny, allow
  Allow from all
</Proxy>

that?

[wet breach]

Yes

[torn shuttle]

I kinda tried

it wasn't happy

seems like the stuff in proxy isn't correct

[wet breach]

Remove the space for deny,allow

[wet breach]

Hmm. Not sure why its freaking out about this setting lol. Uh try creating a new line for allow all? It really shouldnt be complaining about this

[torn shuttle]

oh ok got it

cool now nothing works but at least apache boots

[wet breach]

Lmao

[torn shuttle]

so this isn't correct for trying to access magmaguy.com/wiki.html

[wet breach]

Are you trying to accesss repo?

[torn shuttle]

and repo.magmaguy.com goes to my mc server's page which is the machine's default since it's all hosted from the same machine

[wet breach]

And your url in that error is missing a slash

[torn shuttle]

I'm trying to make repo.magmaguy.com go to magmaguy.com:50001 which is the reposility repo I have and make it give an ssl cert

[wet breach]

Oh ok

[torn shuttle]

cool

I think it's circular now

[wet breach]

Lmao. So why are we trying to go from repo to main domain?

[torn shuttle]

we aren't

magmaguy.com is a website, magmaguy.com:50001 is a reposilite repo running off of docker

[wet breach]

Ok. Does it have an internal ip that the host can reach it from?

[torn shuttle]

I mean it seemed to be working earlier so I assume yes

[wet breach]

So when we redirect dont specify the domain. Just use the internal ip instead for the reverse

We dont want the proxy doing any lookups on the hostname

[torn shuttle]

would that be the proxypass?

[wet breach]

Yes reverse and pass

Set those to the ip address instead

So http://ipaddress

The docker should not try to serve an ssl cert if connection comes from the host

Apache is going to handle the ssl cert to the client

[torn shuttle]

I don't think I'm even doing this in the right place

this is modifying the redirect for magmaguy.com and not the one for repo.magmaguy.com

now I'm redirecting magmaguy.com to repo.magmaguy.com

[wet breach]

Well you didnt tell apache to respond to repo domain

[torn shuttle]

I did in the current settings

[wet breach]

So change the vhost to repo.magmaguy.com lol

[torn shuttle]

well I think I did

do I need it elsewhere as well?

[wet breach]

In the vhost bracket where you specify the domain

Add your subdomain to that

And then apache will start responding to repo

[torn shuttle]

ok well then shouldn't that go on the repo.magmaguy.com.conf instead of the magmaguy.com.conf file then?

I thought we were merging them but it sounds like they maybe should be separate after all

[wet breach]

So it should be repo.magmaguy.com in the vhost bracket

Well is apache also handling your magmaguy.com domain?

[torn shuttle]

yes

it's handling all of my domains

[wet breach]

Ok....so we need to specify all the domains in their respective vhost brackets then lol

I will probably need to get at my computer to create an appropriate conf file

I have some saved

[torn shuttle]

I got it

same file, two different vhosts for 443

one for magmaguy.com one for repo.magmaguy.com

all seems to be working now thanks

[wet breach]

Yes, but for repo we are not going to use magmaguy.com for where we are proxying too

Unless you got it working in which case i guess leave it be lol

[torn shuttle]

yeah I got it working, let's not mess up a winning formula

all domains are correctly certified and directing to the right places

[wet breach]

Yep. Glad i am super familiar with apache that i can provide help using my phone lmao

[torn shuttle]

thanks for helping I absolutely loathe this kind of work

it takes a few hours to understand how things work every time and then the next time I touch it again is 5 years from now and I'll not remember anything I've learned

[wet breach]

Lol odds are i will probably still be here

[torn shuttle]

at least this time around I pruned a lot of dead code

[wet breach]

[torn shuttle]

aight bet ping you in 5 years then

[wet breach]

https://tenor.com/view/the-simpsons-homer-simpson-its-a-date-date-youve-got-a-date-gif-24425106

[wet breach]

If you are using reposilite why are we using apache to reverse proxy? Last i recalled reposilite can serve pages on its own

Is it because of the docker?

[torn shuttle]

ssl

also it was doing an ugly ip for the page where a subdomain would be much nicer

also also it's what they recommend on their docs so

who am I to contest that

oh boy now I get to look at the hundred or so support tickets I got in the time I spent sleeping and setting this up

[pale hazel]

I have never worked the Spigot API before. Do I need tutorials in order to get started?

[torn shuttle]

oh yeah @wet breach since you like websites any clue why a server in taiwan is hitting me with a no route error when trying to get a resource pack from my server in canada

[floral drum]

Have you done java/kotlin programming before?

[pale hazel]

Yes I have programmed in Java before.

[torn shuttle]

honestly if it wasn't for the fact that it seems to be an intermittent error I would almost think it's due to some ip blacklist at a national level or something

[floral drum]

Okay, I would recommend googling some tutorials to get into the spigot api. Unless you want to experiment

[torn shuttle]

don't do that

[floral drum]

hi magma

[torn shuttle]

https://www.spigotmc.org/wiki/spigot/ do it the correct way

https://www.spigotmc.org/wiki/spigot-plugin-development/ this to get started, the other page for the resources

well guess the latter page also has a link to the resources

whoever capitalized this one is a troll

[floral drum]

real

honestly never knew that page existed

[pale hazel]

I'll give this a try

[torn shuttle]

that's because people with brainrot go straight to watching 5 year old tutorials on youtube where you just copy along with your brain off

[floral drum]

well I learnt from tutorials around 7 years ago

[torn shuttle]

case in point

[floral drum]

not tutorials from 7 years ago... well right now they are around that

but yknow what I mean

[wet breach]

I would have to look at connection log to determine cause. It could be a DOS attack where the ip was swapped out for the return. There is settings you can enable networking wise to prevent your server from trying to acknowledge such packets

[torn shuttle]

no like it's a client who gets a no route to my server in canada, he isn't attacking me or anything

just a guy trying to use my service

[wet breach]

Oh. Then its most likely their isp

The probably have border gateway that is dead or has bad routes in its list

Best they can do is use a proxy to try and get connection to route around the bad gateway

[blazing robin]

hey guys can I make a new custom enchant? (like, super pickaxe 3x3 breakable enchant) ,, etc (Im using 1.20.1)

[worthy yarrow]

yeah? lol this has been done since 1.8 and prior even

[blazing robin]

public abstract class TestCustomEnchant extends Enchantment {

    private final String name;
    private final int maxLevel;
    private final EnchantmentTarget target;

    public TestCustomEnchant(String name, int maxLevel, EnchantmentTarget target) {
        super(NamespacedKey.minecraft(""));
        this.name = name;
        this.maxLevel = maxLevel;
        this.target = target;
    }

    @NotNull
    @Override
    public String getName() {
        return name;
    }

    @Override
    public int getMaxLevel() {
        return maxLevel;
    }

    @NotNull
    @Override
    public EnchantmentTarget getItemTarget() {
        return target;
    }

    @Override
    public boolean canEnchantItem(@NotNull ItemStack itemStack) {
        return true;
    }
}

like this?

[worthy yarrow]

uh idk if you have to override all the methods but it looks fine to me

[blazing robin]

hmm but idk how to registry my custom enchantment

[paper viper]

You should use a proper namespaced key instead of just an empty one

[worthy yarrow]

I don't remember if we still have to unfreeze the registries

[blazing robin]

unfreeze? thank you i'll search it

[ancient forge]

how can i remove the ai from a mob causing it to not attack and not move around

is it possible to do without nms

[eternal oxide]

:0aste

?paste

[undone axle]

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

[torn shuttle]

am I being dumb? https://paste.md-5.net/axosikaqim.cs how am I supposed to run the private field "d" in the Display class? I think I am skipping a step or something

it's been a hot minute since I've tried something like this

at least I thought it was "d"

it still tries to run from ItemDisplay instead of Display

[eternal oxide]

why reflection when the API has the method?

[torn shuttle]

uuuh

does it

[eternal oxide]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/entity/Display.html

[hybrid turret]

I want to have async background saving to a db.

Could I just register one ChachedThreadPool singleton and keep submitting stuff to it throughout my plugin?

[torn shuttle]

huh how come...

it's not appearing on this project, remind me wasn't there a trick dumb to this for 1.21

[worthy yarrow]

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

I'm not really sure what else should be done lol, any ideas?

[torn shuttle]

ok wait I think I'm being dumb on multiple levels with this

[eternal oxide]

I've not heard of any tricks for methods not showing up, other than really recent and not using latest

updates IJ to

[torn shuttle]

right because this entire entity is nms is why

which is because this entity is packet only, which

hm

[eternal oxide]

ah

[torn shuttle]

I'm honstly kind of lost but iirc either spigot doesn't let us do packet only entities or something about what i was doing here couldn't be done via spigot

is it possible to do packet only entities via spigot at this stage?

[eternal oxide]

no

[torn shuttle]

ok well i guess that's why

any idea how I'm doing the access there incorrectly?

[eternal oxide]

Should you not get teh method of Display not the instance?

[torn shuttle]

that's kind of what I was trying to do with casting but clearly not correctly

            Display display = itemDisplay;
            Class<?> entityClass = display.getClass();

            // Get the private method
            Method setPosRotInterpolationDuration = entityClass.getDeclaredMethod("d", int.class);

            // Make the method accessible
            setPosRotInterpolationDuration.setAccessible(true);

            // Invoke the method with an argument of 1
            setPosRotInterpolationDuration.invoke(display, 1);

            System.out.println("Method invoked successfully");

[pseudo hazel]

whats the point of the interface if you are just using aregistry to inherit from anyways

[worthy yarrow]

Concrete design

[eternal oxide]

Display.class.getDeclaredMethod probably

[pseudo hazel]

nothing concrete about an interface

idk what you mean by that

[worthy yarrow]

I read it wrong

dude i am so tired

[blazing robin]

Hey guys, I'm trying to create new enchant but

public class TouchOftheFurance extends TestCustomEnchant {

I mean

            // Get the private method
            Method setPosRotInterpolationDuration = display.getClass().getDeclaredMethod("d", int.class);

            // Make the method accessible
            setPosRotInterpolationDuration.setAccessible(true);

            // Invoke the method with an argument of 1
            setPosRotInterpolationDuration.invoke(display, 1);

basically the same as before, still the same error

am I not getting the display class from that?

well, I am not, the real question is why am I not

Caused by: java.lang.RuntimeException: java.lang.NoSuchMethodException: net.minecraft.world.entity.Display$ItemDisplay.d(int) still seems to access ItemDisplay

[eternal oxide]

which is why you shoudl just use Display.class

[worthy yarrow]

I'm using the interface for the base methods, then using the abstract to define standard implantations, also at this point I don't even need to do anything with the implementing classes except define the generics, so I just feel it's kinda nice lol

[pseudo hazel]

right but do to this you need an abstract class and interface, as just a class would be sufficient

or abstract class I guess

[worthy yarrow]

You're missing the point

[pseudo hazel]

and then create your inv registry from that

yeah

i probably am

[worthy yarrow]

I don't have to do anything with the actual implentations is basically what I was going for

just define the generics for each registry

[torn shuttle]

ah yeah you were right

[pseudo hazel]

I know why you used generics

[torn shuttle]

I thought that was the first thing I tried

[smoky anchor]

I would probably advice you to update to 1.21 and use a datapack to register an "empty" enchantment.

[torn shuttle]

but I guess I got lost in the shuffle of debugging maven

[pseudo hazel]

but like there is no difference between IRegistry and ARegistry

[torn shuttle]

my poor wolf what did I do to it

[pseudo hazel]

when would you use something that implements IRegistry that isn't ARegistry?

[blazing robin]

no I have to use 1.20.1 'cause my client using that version

[smoky anchor]

Tell them to update then smh

[blazing robin]

I think they would not update

'cause it's not enough time to open day

[pseudo hazel]

rn it just looks like a C header and implementation

[worthy yarrow]

The interface says this is what all registries have, the abstraction provides partial implementation but also allows you to modify what you want (if you wanted to anyway)

I have to sleep

[pseudo hazel]

yes

[worthy yarrow]

I am almost gonna fall on my computer

[pseudo hazel]

then you should have gone multiple hours ago xD

[smoky anchor]

Check how vanilla registers new enchantments
Find the registry
Unfreeze it, I'll try to find something that will help you with this step
Register your enchantment and the freeze it again

[hybrid turret]

Anyone a take on this? ^

[blazing robin]

I already registed my enchantment

    @SneakyThrows
    private void registerEnchantment(Enchantment enchantment) {
        Field field = Enchantment.class.getDeclaredField("acceptingNew");
        field.setAccessible(true);
        field.set(null, true);
        Enchantment.registerEnchantment(enchantment);
    }

[worthy yarrow]

Idk what to tell ya man I just like to code all day

til I literally cannot think anymore

I wanna try to explain one last time

[pseudo hazel]

yeah I guess that's how you end up with over engineered code.. xD

I get why you did it because most people think its the best way

but in this case especially I dont see a reason to implement IRegistry instead of extending ARegistry

like realistically

so I guess unless you wanna release this as some API the interface doesnt really have a good use

[worthy yarrow]

I have the interface to define the concrete methods right? The abstraction is there to provide partial implementation if you want it, you don't need to but it's there for the benefit of reusable code, it depends on the use case but I feel having a partial implementation is nice when a lot of logic is common

[smoky anchor]

That does not seem right
You're changing Enchantment class, that has nothing to do with Registries

[worthy yarrow]

especially when it comes to registries

[pseudo hazel]

right, im just saying that the partial implementation in this case looks like the ideal final implementation for how you would wanna interact with the interface

I mean maybe thats because you are planning to add more stuff to ARegistry but on its own looks complete

[worthy yarrow]

It just depends if you'd want to do something different from the implementation of aregistry

[pseudo hazel]

like use a different backing map?

i guess but I would be hardpressed to find anything that would work better than what aregistry provides

[smoky anchor]

@blazing robin I found the method that can give you a hint
#help-development message

[pseudo hazel]

but like this is a small thing anyways

[blazing robin]

then what should I use method?

[pseudo hazel]

the code itself looks fine

[worthy yarrow]

I just think it's nice to at least provide the option

You never know what crazy stuff someone might do

[pseudo hazel]

thats why youd not wanna give them the option

[worthy yarrow]

My use case probably wouldn't differ from aregistry

[worthy yarrow]

it's on them if they want to break stuff kek

[pseudo hazel]

when I program I dont wanna accidentally write poor code because my interfaces just allowed me to

[worthy yarrow]

Again I just feel the option is nice to provide

[smoky anchor]

See the message where I tagged you

[worthy yarrow]

welp now you made me wanna put it in the mega thread kek

[pseudo hazel]

lmao

[blazing robin]

but Idk what is getField method

[pseudo hazel]

for what you were asking at the start it would be a good fit there anyways

[worthy yarrow]

yeah fair

itll just get backlogged here

[pseudo hazel]

anyways I also have to go now

[worthy yarrow]

alright take care man

[smoky anchor]

An excercise left to the reader :)
It's just some simple reflection, you can do that yourself

I think the first argument is the class you want to get the field from
Second is its type
Third is its order number (idk how to explain that)

[torn shuttle]

I seem to recall it was possible in intellij to add custom buttons here no? Kinda want to add a button for installing and one for deploying

[rough drift]

Chat, opinion:

Do I move away from things like NamespacedKey and make my own? I am slowly moving my framework to be cross-platform, most of it already should work on Fabric too however there are some bukkit things still, such as the aforementioned

[rough ibex]

just click ... and edit

but you can't add buttons; only change the options in the dropdown

[pseudo hazel]

sounds like you already have an answer, if you know you need to change it to be multi-platform, whats stopping you?

[rough drift]

The main issue I have is, how do I make it still work properly across both? All bukkit methods take in NamespacedKey, and I can't add a conversion function in my own key because then it would defeat the purpose

and MC takes in it's own key

granted I can just convert it in the impl

so that wouldn't be an issue

nvm

[torn shuttle]

I swear I added a button once

hmmm

am I losing it

[rough ibex]

menus and toolbars?

it's not very obvious

[blazing robin]

public static Enchantment enchantment = new TouchOftheFurance();

    private void register() {
        boolean registered = Arrays.stream(Enchantment.values()).toList().contains(enchantment);

        System.out.println(registered);
        if (!registered) {
            registerEnchantment(enchantment);
        }
    }

    @SneakyThrows
    private void registerEnchantment(Enchantment enchantment) {
        Enchantment.registerEnchantment(enchantment);
    }

when I logged it it returned true but the name doesn't appear

[smoky anchor]

What is Enchantment.registerEnchantment
Show me the method

And where do you expect the name to be

[blazing robin]

that's just spigot source code it's on package org.bukkit.enchantments.Enchantment;

[smoky anchor]

Do not do that

Did you use any resource or tutorial while doing this ?

[blazing robin]

https://www.youtube.com/watch?v=wd1FUOT-BJY

I followed this tutorial

[wraith delta]

What might you use in alternative to actually help the user?

[blazing robin]

indeed

[smoky anchor]

Follow what NMS does. Register custom enchant in that way.
It should work until 1.21

[wraith delta]

which would be a risk of incompatibility of the next minecraft versions

[smoky anchor]

I do not believe they care about that, they use only 1.20.1

[blazing robin]

so should I use NMS ?

[blazing robin]

correct

[smoky anchor]

I believe this is outdated

Or at least half outdated.
The lore part is probably still in place, you gotta do that.
But if you want to make a custom vanilla like enchant, probably do what NMS does.

[blazing robin]

hmm 'cause it's 1.15 version?

[smoky anchor]

'cause mojank changed how enchantments are registered probably

[blazing robin]

so for now, 1.20.1 how can I make a new custom enchantment?

[smoky anchor]

One user stated that this method no longer works on 1.20.3

[smoky anchor]

Let me ask you this, do you need this enchant to show up in enchanting table, be usable in anvil as book and stuff ?

[blazing robin]

yeah I have to show up in enchanting table and be usable in anvil as book and stuff

[smoky anchor]

Again, updating would make this infinitely much easier but.
As I said before, unfreeze registry, register enchantment as vanilla does, freeze registry.
On spigot side you will have to add the lore when items get enchanted with your enchant.
Not sure how to handle enchanting table, that one is a bit special I believe.

Try to find more guides for this, not ones 4 years old tho.

[blazing robin]

So, I have to use freeze registry but again,

public static void unfreezeRegistry(Registry<?> registry) {
        try {
            Field intrusiveHolderCache = getField(MappedRegistry.class, Map.class, 5);
            intrusiveHolderCache.set(registry, new HashMap<>());

            Field frozen = getField(MappedRegistry.class, boolean.class, 0);
            frozen.set(registry, false);
        } catch (ReflectiveOperationException e) {
            e.printStackTrace();
        }
    }

in this code, I don't what is MappedRegistry class, and getField

[smoky anchor]

MappedRegistry is NMS class
getField is a custom method, I already described it, scroll up

[blazing robin]

https://www.spigotmc.org/threads/1-20-2-how-do-you-register-enchantments-now.629029/

or what if this? it's only works 1.20.2+ literally?

[smoky anchor]

That is probably just their tested version
I do believe it will work for 1.20.1 as well

[blazing robin]

thank you I'll try it

[torn shuttle]

anyone remember off the top of their heads what mc version 1.20 R2 maps to?

1.20.2 right?

[karmic falcon]

hi, is there a way to work with worlds without having them saved in the server folder, maybe inside my plugins data folder

[eternal oxide]

you can move the location of a world by extending its name with path.

like \..\myWorld

[karmic falcon]

i still dont get it, i have to move myWorld from the plugins folder to the main server folder?

[pseudo hazel]

my plugin just creates new worlds

they are stored in the plugin folder

[karmic falcon]

how do u load them?

[pseudo hazel]

PluginFolder/worlds/world for example

well using the path as the name

[karmic falcon]

WorldCreate worldCreator = new WorldCreator(path of the world?);

[karmic falcon]

ohhh

i tried it tho

[pseudo hazel]

a world name is just the path it takes to get there

[karmic falcon]

but it doesnt work

if i palce it in the main server folder i just write its name yeah?

[pseudo hazel]

this is how I do it https://github.com/Steaf23/BingoReloaded/blob/main/BingoReloaded%2Fsrc%2Fmain%2Fjava%2Fio%2Fgithub%2Fsteaf23%2Fbingoreloaded%2Fdata%2Fworld%2FWorldData.java

specifically createWorld

[royal heath]

Weird question, but what are the cons of uploading a library to github packages and having users use the maven.pkg.github.com repo rather than using jitpack? Are there any?

[blazing ocean]

you have to provide your github credentials

[blazing ocean]

not only to publish but also to use public packages

it's fine for internal stuff just sucks for public libs

[royal heath]

Oh wow really? Okay sounds good. I'll look into using jitpack then

[onyx fjord]

I'm using the conversation API for the first time, is there any way to prevent showing the players string input in chat?

Every time player inputs something the input value is sent raw in chat

Fixed 🙂 it's called local echo

[astral pilot]

how do u run task on main thread from an asynchronous task

[rough drift]

Bukkit.getScheduler().runTask

[quaint mantle]

just use the async chat event

cancel the event if the player is in a conversation

[quaint mantle]

if you plan on publishing on modrinth, they offer maven hosting for every artifact you upload

[acoustic pendant]

Hey, I was trying to use multiple nms versions and made some modules...
But I had a question to use libs such as adventure in spigot, do I have to relocate it in the dist pom.xml or in the core pom.xml??

[quaint mantle]

why relocate ?

[acoustic pendant]

Wdym

[slender elbow]

you relocate the final jar

so, whichever maven module you get the final jar from

[onyx fjord]

Isn't that more problematic with chat color plugins?

[acoustic pendant]

So the dist pom.xml I guess

Thanks

[slender elbow]

kacper just use the echo thing, that's the intended way

[smoky anchor]

#help-server

[silent ridge]

Oi

Ok*

[grim ice]

is it possible to let a crafting recipe include many choices?

e.g you can use spruce logs instead of oak logs

[smoky anchor]

Use tags instead of singular item type

[grim ice]

I don't think that's possible to do with a ShapedRecipe

I'd need to listen to the crafting event

[remote swallow]

use MaterialChoice

with a tag

[vague topaz]

I'm trying to change the direction of a chest using this code in Spigot 1.8.8

Block centerBlock = location.getBlock();
centerBlock.setType(Material.TRAPPED_CHEST);
centerBlock.getState().setData(new Chest(BlockFace.WEST));
centerBlock.getState().update();

But it always spawns in north direction

[chrome beacon]

getState returns a copy

[vague topaz]

but there is no setState

[chrome beacon]

you use the update method

[vague topaz]

I do?

[chrome beacon]

getState -> copy
update -> set said copy back without changes

see the issue?

[vague topaz]

no, sorry

[chrome beacon]

You're never setting the facing before updating

since you have two different block states

you're setting direction on the first one

[vague topaz]

alright I understand now

So it should be?

Block centerBlock = location.getBlock();
centerBlock.setType(Material.TRAPPED_CHEST);
BlockState state = centerBlock.getState();
state.setData(new Chest(BlockFace.WEST));
state.update();

[chrome beacon]

yes

[vague topaz]

yeah, it works now, thanks

[chrome beacon]

though I've never used the chest class like that 🤷‍♂️

since it's been deprecated for so long

[knotty swan]

Hey I have an question how could I implement the canplaceon/canbreakblcok tags in 1.21 since those got changed

[chrome beacon]

I don't think there's API for that atm

[blazing ocean]

PDC no?

[chrome beacon]

Might have to use NMS

[chrome beacon]

Those are vanilla tags

PDC won't help here

[blazing ocean]

I thought PDC was able to change those

[chrome beacon]

It's not

[slender elbow]

pdc isn't raw nbt access

[chrome beacon]

All PDC values are stored in the BukkitValues nbt tag

[slender elbow]

it's scoped

[tender shard]

yes, one second

[tender shard]

done (version 1.0.3-SNAPSHOT)

[hasty prawn]

thank you good sir

[karmic falcon]

hi, i was wondering what is the best way to make a temporary world, currently i copy it and place it somewhere else and load that copy then delete it, and another thing is how do you load a world specifically for this case, do u delete all the folders containing data

[lethal dune]

Can somebody help me made some commands but if i execute them nothing happens even if they should do smth

[tender shard]

show your command executor and how you're registering them

[lethal dune]

public class TestInterfaceCommand implements CommandExecutor {
public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
if (command.getName().equalsIgnoreCase("duel")) {
if (sender instanceof Player player) {
Inventory inventory = Bukkit.createInventory(player, 1, "Test Interface");
ItemStack wool = new ItemStack(Material.BROWN_WOOL);
}
else{
sender.sendMessage("Only Player Commands do not use");
}
}
return true;
}
}

--
getCommand("tic").setExecutor(new TestInterfaceCommand());

[undone axle]

You can use the discord code block format to display code or just text in a more pleasing way:
```java
public class MyPlugin extends JavaPlugin {
@Override
public void onEnable() {

}

}```
Becomes:

public class MyPlugin extends JavaPlugin {
    @Override
    public void onEnable() {

    }
}```

[smoky anchor]

Your command is "tic" not "duel"
this will always fail like this.

And for completeness sake, don't forget to register your commands in the plugin.yml

[smoky anchor]

By this I mean the command.getName().equalsIgnoreCase("duel") will always fail as the command name is "tic"

[lethal dune]

yes i understand and i changed it but its still the same and yes i have it in the plugin.yml

[tender shard]

why are you checking the command's name in your executor?

remove the part where you're checking the command's name

[lethal dune]

do you mean like this

public class TestInterfaceCommand implements CommandExecutor {
    public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
        if (sender instanceof Player player) {
            Inventory inventory = Bukkit.createInventory(player, 1, "Test Interface");
            ItemStack wool = new ItemStack(Material.BROWN_WOOL);
        }
        else{
            sender.sendMessage("Only Player Commands do not use");
        }
        return true;
    }
}```

[tender shard]

yes

however your command still won't do anything

you only create an empty inventory and then don't do anything with it

[lethal dune]

or for example this command
it doesnt work too

public class duelCommand implements CommandExecutor {
    public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
        if(sender instanceof Player)
        {
            Player p = (Player) sender;
            if(args.length == 0)
            {
                p.sendMessage("Not enough arguments");
                p.sendMessage("Format: /duel <player>");
            }
            else{
                String DuelPlayer = args[0];
                Player target = Bukkit.getServer().getPlayerExact(DuelPlayer);
                if (target != null)
                {
                    p.sendRawMessage("well... it looks like you wanted to duel " + target + " But i was too lazy to code this so yea. yea");
                    target.sendRawMessage("well... it looks like" + target + " wanted to duel you but i was too lazy to code this so yea. yea");
                }
                else
                {
                    p.sendMessage("Player is not online!");
                }
            }
        }
        return true;
    }
}

[lethal dune]

.

[pseudo hazel]

does it get suggested in mc?

did you put the commands in plugin.yml?

[lethal dune]

yes it does get suggested

[eternal oxide]

then you didn;t register an executor

By default commands in teh plugin.yml fire an onCommand in the JavaPlugin

unless you register an executor

[lethal dune]

i did

getCommand("duel").setExecutor(new duelCommand());

[eternal oxide]

is that in your onEnable?

[lethal dune]

yes

package me.Antares.uHCraftPlugin;

import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.plugin.java.JavaPlugin;

public final class UHCraftPlugin extends JavaPlugin {


    @Override
    public void onEnable() {
        boolean IsGod = false;
        getServer().getPluginManager().registerEvents(new JoinLeaveListener(), this);
        getCommand("god").setExecutor(new GodCommand());
        getCommand("duel").setExecutor(new duelCommand());
        getCommand("tic").setExecutor(new TestInterfaceCommand());
    }

    @Override
    public void onDisable() {
        // Plugin shutdown logic
    }

}

[eternal oxide]

also add an @Override to your onCommand method

[lethal dune]

i did now still nothin

[eternal oxide]

Check yoru server latest.log for any startup errors

and DO NOT replace the plugin jar on a running server. Stop the server, replace jar, start server.

[lethal dune]

Oh well thanks it think that fixes it

[rough hinge]

https://paste.md-5.net/kucovozoqi.cs why this happens?

https://imgur.com/a/WRvpD9r

[hard socket]

what happens?

[rough hinge]

it was supposed to be -1 and not -3

[rough hinge]

see the debug too

[hard socket]

you are setting it to -3?? clickedItem.setAmount(-3);

[eternal oxide]

then you are settign to AIR so once teh inventory updates there is no stack

[hard socket]

https://paste.md-5.net/xelacurute.cs
this is duplicating the chestplate

[rough hinge]

see after

i setted -1 after

[eternal oxide]

you can't set -1 to AIR

[rough hinge]

then how i remove the item ?

[eternal oxide]

you set to AIR and update

[rough hinge]

update the inv?

[hard socket]

PlayerInventory#removeItem

[rough hinge]

why not playerinventory#remove(itemstack)?

[hard socket]

well I dont memorize methods

use that

[eternal oxide]

Modifications to slots that are modified by the results of this InventoryClickEvent can be overwritten. To change these slots, this event should be cancelled and all desired changes to the inventory applied. Alternatively, scheduling a task using BukkitScheduler.runTask(Plugin, Runnable), which would execute the task on the next tick, would work as well.

[safe furnace]

Hi, so. I was trying to make a command that shows statistic of other player, ex: /check @safe furnace and then the stats..
How can I make this with DispatchCommand?

[eternal oxide]

why would you DispatchCommand?

[rough hinge]

whats the differnece?

[hard socket]

bro just use yours

[rough hinge]

if have many itens with same lore and amnount, will remove the first

and i dont want this

i want remove the clicked item

[safe furnace]

Oh yeah, you're right. I can use PlaceHolders..

[pliant topaz]

get the clicked slot and only remove one from that or directly set material to air as someone alr said

[hard socket]

https://paste.md-5.net/uyomoviquc.cs doesnt work

[safe furnace]

What should be problem?

[blazing ocean]

papi not being there

idk what else people are supposed to tell you as you have provided zero information

[lost matrix]

Show your pom

[safe furnace]

First ^^

Second, the placeholderapi it stays red at pom.xml

[blazing ocean]

add their repo

and show the whole pom and not just a small snippet

[safe furnace]

I added.

Make sure to reload the maven project so that the dependencies are resolved properly

And java version 1.8 for minecraft 1.21 is wild

[safe furnace]

Ik

[safe furnace]

Yeah, ty.. thats fixed the problem.

but this doesn't

Ignore bukkit.dispatchcommand

Oh, i forgot to import the class.. i fixed it.

[earnest girder]

    public TextDisplay getDisplay(Location location) {
        World world = location.getWorld();

        double radius = 5;

        Collection<Entity> nearbyEntities = world.getNearbyEntities(location, radius, radius, radius);
        System.out.println(nearbyEntities);

        for(Entity entity: nearbyEntities) {
            if(entity instanceof TextDisplay) {
                return (TextDisplay) entity;
            }
        }

        return null;
    }

This method keeps returning null and printing an empty list no matter the radius. The location I'm inputting is the exact location of a TextDisplay.

It is being called in onEnable

[chrome beacon]

If you're storing the location why not store the uuid

and get the entity by that

[rough hinge]

if i set type with burning_furnace, the furnace if not have ores, will be disabled?

[chrome beacon]

try it and see

[lost matrix]

Locations are extremely unreliable as references. Use any other means to get your Objects.

Hey, I am trying to spawn a player like npc with nms 1.21 but I only got this error. Does anybody know a solution?

https://paste.md-5.net/jofirejaho.java (Code + Error on the bottom)

~ @uncut grove

[rough hinge]

then disable

[chrome beacon]

You need to give your npcs a dummy connection to void packets

[uncut grove]

How can I do this?

[chrome beacon]

Try the discord search

[rough hinge]

org.bukkit.block.Furnace block = (org.bukkit.block.Furnace) furnace.getLocation().getBlock().getState();

        block.setBurnTime(); have infinite burn time?

[chrome beacon]

This is being asked at a minimum once a week

[rough hinge]

setburntime is on ticks?

[chrome beacon]

yes

[echo basalt]

.

and here's elgar's spoonfeed

[hard socket]

https://paste.md-5.net/akujeloqoz.cs
the item is being duplicated and not null

[rough hinge]

for (Furnace furnace : furnaceService.getAll()) {

        org.bukkit.block.Furnace block = (org.bukkit.block.Furnace) furnace.getLocation().getBlock().getState();
        
        if (!FurnaceController.hasCoal(furnace) || FurnaceController.getSmeltTime(furnace) == 0) {
            block.setBurnTime((short) 0);
            continue;
        }

        block.setBurnTime((short) 1000);

    }

setburntime update block type?

[safe furnace]

Anyways. Can I make them together. Args[0] and papi to one string?

[tardy delta]

what

[safe furnace]

Are u talking to me?

[tardy delta]

yes

[safe furnace]

I was trying to make a command that shows statistic of other player, ex: /check @safe furnace and then the stats..

[tardy delta]

hmm

[safe furnace]

So, If i type /check ...

[chrome beacon]

if you want to get placeholders for the targetPlayer than provide that as the first argument in the setPlaceholders method

[safe furnace]

it says .... and then @safe furnace

so the %player_name% is using that who using the command

[echo basalt]

fairly simple workflow

[tardy delta]

i cant understand anything

[echo basalt]

our boy wants a hardcoded placeholder + parsing stuff for a target player

public void check(Player sender, Player target) {

}

start with this

sender can be the target, up to you

On your command executor, see if a target is specified, if it is, validate it

If it's not, assume it's the sender

[earnest girder]

should I instead store the text display's UUID?

[echo basalt]

I'd store location + uuid and maybe name

In case the text display is gone and you need to respawn it

[hard socket]

why cancelling InventoryClickEvent doesn't work when players are in creative??

[eternal oxide]

creative is boss

[hard socket]

bruh makes no sense

[slender elbow]

creative mode is a disaster

[eternal oxide]

If you have access to creative the server accepts whatever the client tells it

[slender elbow]

it has basically complete authority over the inventory

although it isn't quite like that, it makes it very awkward to write server code for

[hard socket]

well there is a reason no one made a plugin for creative use

but that just sucks

[slender elbow]

the solution is to just not give real creative mode to players

a great example i've seen to that case is hypixel housing

you don't have real creative mode but you have all the thingies you would normally expect from creative mode

[hard socket]

yeah that's true

they have a whole menu just to not use creative

[slender elbow]

uwu

wrong chat

[tardy delta]

wtf

[ornate mantle]

im trying to make a custom nms iron golem that uses the zombie pathfinders, but it still uses the iron golem pathfinder goals

is there a way to clear all pathfinder goals?

[chrome beacon]

You can use the removeGoal method or stop the goals from registering in the first place

[ornate mantle]

the method registerGoals() in the IronGolem class registers them

but i can't find any place where it is called

and somehow it still follows each goal in the method

like being passive and attacking zombies

[chrome beacon]

You can just override registerGoals

and put your own goals

[ornate mantle]

legit just did that

you can call methods, but the server will not tick until the task ends

ok thx

int firstOresIndex = FurnaceController.getFirstOresIndex(furnace);
int firstSmeltedOresIndex = FurnaceController.getFirstSmeltedOresIndex(furnace);

            furnace.setCounter(0);
            continue;
        } Does Java only create the 2nd variable if the 1st condition is false?

[ivory sleet]

both are created

but ofc only the first one may get evaluated yk

like if firstOresIndex == -1 then there's no point in checking the second one

anyway, had u just passed some mere ints to the variables like
int a = 1
int b = 2
or so then it may actually optimize it further, but those method calls getFirstOresIndex and getFirstSmeltedOresIndex cannot be ignored

[tardy delta]

both functions get called

[ivory sleet]

yep

[tardy delta]

sounded like you were saying the opposite

[ivory sleet]

i mean for the if statement itself, the compound boolean logic may not have to be fully evaluated if the first formula is true

[rough hinge]

I will create the 2 variables even in some cases just creating one. I will opt for legbiility and not performance.

[ivory sleet]

myea sure

[rough hinge]

I don't just do a boolean because the index is useful later to avoid going through more lists

[ivory sleet]

mye

[tardy delta]

dont bother doing that kind of optimizations

sure every tick (50 ms so)

all loop should be espaced by 1 tick

[torn badge]

Well yeah then you have all of these tasks accessing the list from different threads

[sterile breach]

because I call thread.sleep you mean?

[torn badge]

No, because you have a for loop

[sterile breach]

loop is inside the thread so all looping are in the same thread no?

Yeah, then you run a new task, while the old one is still running

And you are probably modifying the list somewhere

That's what‘s throwing the exception then

sure but I copy it here so if my list at records.get... is modifed r is not no?

ArrayList<Action> r = records.get(player.getUniqueId());

new ArrayList<>(r) would be a copy

Hey guys i am coding in nms right now and i get an Exeption "Caused by: java.lang.NullPointerException: Cannot invoke "net.minecraft.server.network.PlayerConnection.k()" because "var0.c" is null" But so far i know is there no more PlayerConnection class in 1.20.6 / 1.20.4

does anyone know which could cause this Exeption?

[mellow edge]

I need help. I made a minigame and I want it to support bungee-like servers, and I don't know what I should do when the game ends. Maybe redirect the players to another server on the network?

Because I want the servers owners to be able to manage that, because the plugin will be public.

[tardy delta]

well c is null 🗿

show code

[zenith bobcat]

yeah in PlayerConnection class

[zenith bobcat]

but PlayerConnection class doesnt exist in the minecraft code

[tardy delta]

remapped ig

[pseudo hazel]

why does IJ ask if I wanna make a resorc instead when I have a final List?

like isnt it kinda icky

cuz you can still just mangle around in the list

even though its a record..

[rough hinge]

https://paste.md-5.net/ubixopesoy.rb any sugegstion to improve?

[pseudo hazel]

I guess that goes for any non primitive object...

[tardy delta]

cuz java records are stupid

[tardy delta]

switch

[pseudo hazel]

yeah fair I guess

[peak depot]

any one got that chars?

like the small minecraft font

[pseudo hazel]

seem to be some base value and each following value adds 16, that sounds like it can easily be a simple if statement

probably using modulo or somthing

[pseudo hazel]

https://small-caps-font-generator.pages.dev/ this one works pretty well imo

[tardy delta]

uh sure

[peak depot]

thx

[rough hinge]

It's even worse. I wanted to find some formula

[tardy delta]

what steaf said probably, check bounds and do a modulo

[rough hinge]

isnt possible

i tried

[tardy delta]

counter % 16 == 0 && counter in 16..=144

[dense falcon]

Redis is the best one as "database" for mc plugin? 🤔

[rough hinge]

depend lol

[pseudo hazel]

yeah the first check is just if (furnace.getCounter() <= 144 && furnace.getCounter() % 16 == 0)

[tardy delta]

redis isnt a db

but whats your arch

[pseudo hazel]

but the second check isnt linear smh

[rough hinge]

thanks

[echo basalt]

what the fuck

itemtype go brr

[pseudo hazel]

wait did I make a mistake?

[echo basalt]

no it's just uh

magic numbr

[pseudo hazel]

well yeah

the source is even more magical

[pseudo hazel]

.

[tardy delta]

just use a switch and the compiler will make it a jump table

dont try to be smarter than the compiler

[pseudo hazel]

yeah true

a switch is good too

but this is just faster to write out too

[onyx fjord]

how do we parse the minecraft version starting from spigot 1.21?

[pseudo hazel]

i;d like to know as well haha

rn I just have expirimental warnings

or wait thats for plugin version

and im on the wrong server...

on paper its just Bukkit.getMinecraftversion()

[eternal night]

hm?

[pseudo hazel]

and I think for spigot it didnt change from before

[onyx fjord]

im tryna understand how to deal with Bukkit.getServer().getClass().getPackage().getName() working differently on paper

[pseudo hazel]

oh

on paper use Bukkit.getMinecraftVersion() xD

[eternal night]

Basically, don't.

not that you even need to just for reflection access

[onyx fjord]

how else am i getting the mc version string

[eternal night]

if you want to load different modules based on the version, then yea, there is ehh

[onyx fjord]

^ thats what i want yeah

[eternal night]

https://forums.papermc.io/threads/important-dev-psa-future-removal-of-cb-package-relocation.1106/

So just Bukkit.getServer().getBukkitVersion();

but for reflective lookup of like CraftEntity you'd just store the Bukkit.getServer().getClass().getPackage().getName() and append to that. Maybe that has the relocation, maybe it doesnt, either way its fine

[pseudo hazel]

I know this code is only slightly cursed, but how would I check the cast in this case?

or suggest a better way to make this method I guess xD

[eternal night]

you can't

[pseudo hazel]

hmm okay

so I guess I gotta trust my code that its correct?

or is it an intellij thing

[eternal night]

Yea, generics are erased at java runtime

[pseudo hazel]

ah

so it would spontaneously combust if I messed it up on testing?

thats good

[eternal night]

Welcome to generics at runtime the usual goal is to just not leak this kind of insecurity out of the owning code

e.g. don't make anything else do these checks

[pseudo hazel]

yeah I will only have a static amount of these data types and they are all made by this part of the codebase

but good to know 👍

[tardy delta]

no

would require asking the type of T at the runtime

getParameterizedTypes()

sec

might be Class::getTypeParameters but i see no point in knowing the type of T at runtime

[quiet ice]

I mean by providing a Class<T> you can do that

[tardy delta]

i mean if that ListNode<T> is always storing values of type T and that class is internal, why bother knowing the runtime type, the cast will always succeed

[ivory sleet]

there is a way

but its hella cursed

u can do sth like (Class<SomeClass<T>>) (Type) SomeClass.class

Type meaning the java.lang.reflect.Type one

[echo basalt]

kotlin reified T be like

[ivory sleet]

mye

[tardy delta]

reified works only on inline functions

[eternal night]

Phew thank god spigot doesn't have to do that anywhere

[blazing ocean]

reified is still great

[ivory sleet]

got the type token hackery as well :P

Hello everyone. Im currently trying to implement an API i created into one of my plugins but keep getting errors and right now im stuck on this one and wondered if anyone with more knowledge then me could help.

This is the Main class where i try to get the api and make a getter for it.

    private static Main instance;
    private final API rankAPI = (API) Bukkit.getServer().getPluginManager().getPlugin("rank-core"); <- The API plugin "rank-core"

    @Override
    public void onEnable() {
        instance = this;

        // listeners
        PluginManager pm = Bukkit.getPluginManager();
        pm.registerEvents(new OnChatEvent(), this);

        // commands
        getCommand("getrank").setExecutor(new GetRankCommand());
        getCommand("setrank").setExecutor(new SetRankCommand());
        getCommand("setcolor").setExecutor(new SetColorCommand());
    }

    @Override
    public void onDisable() {}

    public static Main getInstance() {
        return instance;
    }

    public API getRankAPI() {
        return rankAPI;
    }
}```

and when i try to load the plugin i get this error(Anyone knows how to make that shit not null?)
```java.lang.NullPointerException: Cannot read field "getSQL" because the return value of "net.snakkze.rankutils.Main.getRankAPI()" is null
        at net.snakkze.rankutils.listeners.OnChatEvent.<init>(OnChatEvent.java:15) ~[?:?]```

This is the class that causes the error
```public class OnChatEvent implements Listener {

    private final GetSQL sql = Main.getInstance().getRankAPI().getSQL;

    @EventHandler
    public void onChat(AsyncPlayerChatEvent e) {
        Player p = e.getPlayer();
        UUID uuid = p.getUniqueId();
        Rank rank = sql.getRank(uuid);
        
        String format = Main.getInstance().getRankAPI().getCosmeticRankName(rank, uuid) + " " + p.getDisplayName() + rank.getChatColor() + ": " + e.getMessage();
        e.setFormat(format);
    }
}```

hey, I have a question: how can I write a tablist with many columns on version 1.18.2?

[lost matrix]

You basically send packets to your users, which contain playerdata. This data is then resolved to display the username, ping, and head icon in your tablist.

[lost matrix]

initialize your rankAPI field in your onEnable.
And make sure you have defined your rank API plugin in your plugin.yml as a dependency

[peak zealot]

Sorry for bothering but i did what you said and now i get this error because i have both the api plugin and the plugin that uses the api inside of my plugins folder?
java.lang.ClassCastException: class net.snakkze.rankcore.API cannot be cast to class net.snakkze.rankcore.API (net.snakkze.rankcore.API is in unnamed module of loader org.bukkit.plugin.java.PluginClassLoader @3fd30f2f; net.snakkze.rankcore.API is in unnamed module of loader org.bukkit.plugin.java.PluginClassLoader @31cbe119)

[lost matrix]

Are you using the reload command?

Also show your pom

[peak zealot]

yes

[peak zealot]

https://pastebin.com/j4uGbMJ3

[lost matrix]

Did you read the warning in the reload command? Its not supported and will inevitably cause horrific problems.

[peak zealot]

Oh

[lost matrix]

The system scope results in your API being shaded into your plugin. This will result in classloader problems because the same classes are
present multiple times. Im quite sure that this is your problem here.

[peak zealot]

so what do i change it to? provided?

[lost matrix]

Is rank-core your own plugin?

[peak zealot]

yes

[lost matrix]

Alright then here is how to properly handle this:

[lost matrix]

1. Go into your rank-core project
2. Run mvn clean and then mvn install
   install will result in your project being installed into your local maven repository, so that it can be found by all your other projects
3. Go into your rank-utils project
4. Open the pom and change your rank-core dependency to

        <dependency>
            <groupId>net.snakkze</groupId>
            <artifactId>rank-core</artifactId>
            <version>1.0-SNAPSHOT</version>
            <scope>provided</scope>
        </dependency>

Or whatever you defined at the top of your rank-core pom
5) Now mvn clean and mvn package or mvn install your rank-utils project

The scope is either
provided -> This means the classes are provided by someone else on runtime
compile -> This means the classes are not provided on runtime, and will be copied into your project
You always want to use provided when the dependency is another plugin, because other plugins already
exist on the server. The same goes for the spigot-api. Its score is provided because the spigot classes
obviously exist on the server already.

[peak zealot]

Ok thank you. So after i do this i just export both plugins into my plugins folder and run the server and the error should be gone?

[lost matrix]

What do you mean by export?

I mean

[peak zealot]

Like build the artifacts so i get the jars

[lost matrix]

No, you never build artifacts when using maven or gradle

And you never add any artifacts to your project either

[peak zealot]

Ok, so how do i get my jars?

[lost matrix]

You run the proper maven goals

install will run package first, meaning you will end up with your compiled jars

[peak zealot]

Ah ok

[lost matrix]

So after this you have everything you need.
And for the future: When using maven, dont add any dependencies or compile any other way than via your pom.

[peak zealot]

Ok thank you very very much 🙏

Pre-1.21, using this code I could hide the attributes on an item, but using the same code on 1.21 has no effect, did something change that means I have to do it a different way now?

ItemMeta meta = item.getItemMeta();
meta.addItemFlags(ItemFlag.HIDE_ATTRIBUTES);
item.setItemMeta(meta);

[drowsy helm]

You have to change the attribute values now

You can just change them to the default, they just have to be changed

[lavish scarab]

How would I do that?

[drowsy helm]

    meta.setAttributeModifiers(this.item.getType().getDefaultAttributeModifiers());

this might seem weird, but how would i extend snakeyaml's parsing to prefix all sections that are inside a section called "actions" with (ignored=random text)

i don't mean if the parent section is called "actions", i mean if it's in any section called "actions", like this

actions:
  idk:
    idk2:
      "test"```
would be
```yaml
actions:
  (ignored=random text) idk:
    (ignored=random text) idk2:
      "test"

if that makes sense

(during the parsing process, not after)

java.lang.IllegalArgumentException: The embedded resource 'plugins/Minigame/schematics/lobby/lobby.schem' cannot be found in WorkingDirectory\build\libs\Minigame-1.0-dev-all.jar

[quiet ice]

Use the path of separator + "schematics" + separator + "lobby" + separator + "lobby.schem" instead

that is, omit the data folder

[muted otter]

ah, ok\

does it automatically look in the data folder?

[quiet ice]

well - only for the saveResource call that is

[muted otter]

yea i know

[quiet ice]

It won't automatically look into the data folder in that case - that would be silly

saveResource copies to the data folder - provided the file does not already exist

[muted otter]

oh ok

[red onyx]

Moin, ich suche derzeit einen Hauptprogrammierer für einen Minecraft server falls ihr darauf lust habt meldet euch, natürlich springt dabei was rum.

[muted otter]

String separator = File.separator;

saveResource(separator + "schematics" + separator + "lobby" + separator + "lobby.schem", false);

This is what I have now, is this correct?

I am still getting the exception

[quiet ice]

Leute, es ist zwei Uhr

?services Jokes aside, this is the wrong place

[undone axle]

If you wish to request or offer development/art/building/administration services, please do so at https://www.spigotmc.org/forums/services-recruitment-v2.54/

[quiet ice]

what exactly is the warning?

Also, I'm not entirely sure whether File.separator is appropriate here - I'd rather use / unconditionally in this case due to how zip files work

[blazing ocean]

haha

imagine sleeping

[muted otter]

saveResource("/schematics/lobby/lobby.schem", false);

java.lang.IllegalArgumentException: The embedded resource '/schematics/lobby/lobby.schem' cannot be found in WorkingDirectory\build\libs\Minigame-1.0-dev-all.jar

[quiet ice]

[pine crest]

[viscid carbon]

Why's that?

[lost matrix]

I have a

public static void send(CommandSender sender, String message, MessageFormat format, Object... elements)
...
public static void sendInfo(CommandSender sender, String message, Object... elements) {
  send(sender, message, infoFormat, elements);
}

method for default decorations.
All i do is call

Msg.sendInfo(player, "You have {} coins.", 200);

And im done. Automatic object insertion and decoration via MiniMessage.
