[quaint mantle]

thanks!

[shadow night]

Then if you have a config variable with the FileConfiguration don't forget to set it

[sterile token]

if your settings value into config don't you have to save it and then reload? Maybe i have done it all time wrongly

[tender shard]

if you want to load a changed file, then saving what you have in memory is pointless because you'd only load what you have just saved.

[shadow night]

What if I made an implementation of configuration or whatever you implement that uses nbt

[tender shard]

you NEVER want to load a file that you have just saved half a second ago

it never makes any sense

[kindred sentinel]

Is there a way to turn off the light of redstone?

[shadow night]

Isn't light client sided

[young knoll]

No

[kindred sentinel]

I don't think so

[sterile token]

Oh weird i have had problems with data not being saved if i just reload the file. Instead of first saving and them reload

[shadow night]

It isn't? Damn

[young knoll]

Only certain components emit light

Like repeaters

[tender shard]

yes ofc data isn't saved if you load the file

[kindred sentinel]

I just want to make something like optimization, when redstone is turned on it has light so with a lot of mechanisms it overload the server

[tender shard]

if you first save and then load it again, then why do you load it at all? if you just saved it anyway, you already have all the data you need

[kindred sentinel]

So is there a way to turn off the redstone light?

[sterile token]

right, thanks mfalex

[young knoll]

You’d have to do some crazy stuff with internals me thinks

[kindred sentinel]

In addition, it is quite possible that this will not optimize but will only worsen the situation...

[tulip phoenix]

Algum brasileiro aqui pode me ajudar ?

[tender shard]

what?

[kindred sentinel]

He is brasilian and he needs help from brasilians

I think

[tulip phoenix]

I need some help, when I try to add one of my plugins inside my external library and try to call some method of that plugin that I added, it ends up causing this error: package com.yorkans.factions does not exist

I dont understand so much english xD

[tender shard]

are you using maven or gradle?

[tulip phoenix]

maven

[tender shard]

did you add the other plugin as <dependency> to your pom?

[tulip phoenix]

that plugin is one that i created, and i cannot do a dependency, or i dont know how

[tender shard]

Imagine this is your first plugin: group de.jeff_media, artifactId Drop2InventoryPlus.

Now you run mvn install on that project in the maven tab. Now, you can add it as dependency to your other project:

<dependency>
  <groupId>de.jeff_media</groupId>
  <artifactId>Drop2InventoryPlus</groupid>
  <version>4.0.0</version>
  <scope>provided</scope>
</dependency>

mvn install basically just makes your project available to other projects

[tulip phoenix]

really ?

[tender shard]

yes

[tulip phoenix]

i'll try

[kindred sentinel]

I just wonder what would he do if you have replied "no"

[tender shard]

lol

it's not april 1st yet

@full ridge are you using maven or gradle?

[full ridge]

Hi, I'm very new to learning to make plugins (even tho I have a bit of experience with Java) and tried for quite some time now to create a simple 'Hello World' Plugin for a Bukkit server (I know this here is a Spigot Discord, but I couldn't find a bukkit Discord and really have no clue to solve my issue). This is the Code:

import org.bukkit.plugin.java.JavaPlugin;

public class HalloWeltPlugin extends JavaPlugin {
public void onEnable() {
this.getLogger().info("Hallo Welt");
}

public void onDisable() {
}

}

According to the Compiler there are Symbols he can't decipher in line 1 (It points at the dot between java.JavaPlugin), in line 3 (there it points at the J in JavaPlugin) and in line 5 (there it points at the dot between this.getLogger() ). I tried a bunch of stuff but I just can't figure out how to solve it. I hoped someone here could give me a hint in the right direction.

[tender shard]

are oyu using maven or gradle?

[full ridge]

I think maven, at least there are maven jars in my servers library, and no gradle jars

[tender shard]

ok do you have a pom.xml file?

if yes, paste it please:

?paste

[undone axle]

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

[kindred sentinel]

So... Does it really work?! I always use System.out.println instead of "this.getLogger().info"...

😂

[dry hazel]

sout is bad because it doesn't identify your plugin

[full ridge]

I don't think so

[quiet ice]

Just FYI Bukkit died years ago. Bukkit will celebrate it's 10th death-year in august

[tender shard]

ok I suggest you to read my basic tutorial on how to setup IJ and maven for a simple plugin: https://blog.jeff-media.com/how-to-create-your-first-minecraft-plugin-using-the-spigot-api-and-maven/

[full ridge]

Thank you : )

[quiet ice]

You should use some logger function. Although I personally prefer the SLF4J logger over the JUL logger, but that [the JUL logger] is about as good

[tender shard]

np! if you follow that step by step, you should basically end up with a working hello world plugin, then you can just expand that.

[kindred sentinel]

Maybe it's better just to use minecraft plugin to intelij idea for people who is new to plugins?

[dry hazel]

using IJ's build system will just hinder you when you need anything more than building a jar

[tender shard]

i dont think so, the pom it generates is cursed and you won't understand what those options do

for example it adds the shade plugin in a totally outdated version, and even sets createDependencyReducedPom to false, why?

imho it's better to copy/paste my example plugin and read all the comments to understand what those options do

[quiet ice]

createDependencyReducedPom is only really useful for APIs that have the shaded jar uploaded as a separate artifact

[kindred sentinel]

Ok, you're right

[tender shard]

ofc once one knows those options, sure the IJ plugin is quicker. but to get started I'd rather write it from scratch once

[solid cargo]

back to the eclipse days

[tender shard]

that is true but there also is 0 advantage in diabling the reduced pom

it's just an additional setting that might cause problems later and doesnt give any advantage now

[quiet ice]

Actually there is in this very specific case

Outside of the specific case that I just mentioned, there is no real use

[tender shard]

what's the advantage of disabling it?

[quiet ice]

I do it in order to compile https://stianloader.org/maven/de/geolykt/starloader/launcher-sponge/4.0.0-a20240110/ for example

[tender shard]

why wouldnt it compile with dependency reduced enabled?

just saw, mc-dev merged my PR to remove disabling dep reduced by default https://github.com/minecraft-dev/MinecraftDev/pull/2116

[quiet ice]

Because then you'd no be able to consume transitive artifacts by default.

[tender shard]

It only removes dependencied that are included in the artifact. Why would someone need them twice?

[quiet ice]

So either you depend on the shaded artifact (which would make a great time for version conflicts) or depend on all the transitive deps manually - not great either.

[tender shard]

Exactly. The dependenc reduced pom also only is for the shaded artifact. If you upload both, the normal pom is still there for the unshaded artifact

[quiet ice]

There is only really a single pom regardless of the classifier of the shaded artifact

You seem to be confused with what an artifact is in maven - frankly, it can be anything. In this case the shaded artifact is just a file and shouldn't be confused with being a separate addressable project. The shaded classifier is identical to the sources or javadoc jars (in function from the eyes of a maven resolver).

Also the dependency-reduced pom is much more than a simple file. For as long as it is uploaded it will be an additional file (for whatever reason), but once installed on a maven repository it will replace the original pom

[tulip phoenix]

That worked, thank you so much!

[tender shard]

np

[tender shard]

yeah I got that wrong, but still when I deploy both the shaded and unshaded artifact and have dependencyReducedPom enabled, the deployed pom still includes all the dependencies, so I don't really understand how not disabling dependency reduced should create any issues?

[quiet ice]

uh I'll look it up in a sec but I don't actually think that it will

[cursive kite]

How do I check if a "MOVE_TO_OTHER_INVENTORY" moved the item or if the inventory was full and no action happened

[young knoll]

You’d probably have to check if the other inventory can accept it

[tender shard]

https://repo.jeff-media.com/#/public/com/jeff-media/example-dependency-reduced/1.0

the pom includes snakeyaml with the original compile scope even though createDependencyReduced is true

[young knoll]

Via looking for matching stacks that are not full or empty slots

[cursive kite]

Dang it

[tender shard]

although if the dependency reduced pom isn't getting deployed (which it isnt) then I really don't understand what its purpose is lol

[quiet ice]

I'll test it in a bit, don't worry. I have botched a few releases lately I just realized so there is a good reason to reupload jars regardless :)

[tender shard]

i always thought that when deploying both the shaded and unshaded artifact, there'd be the reduced pom for the shaded artifact and the original pom for the unshaded artifact, but it seems like the reduced pom isn't deployed at all, so I really wonder what it's purpose is supposed to be then

from what I just found out though, the deployed pom is always the original pom, no matter whether dependencyReduced is enabled or not

[quiet ice]

https://stianloader.org/maven/org/stianloader/launcher-micromixin/4.0.0-a20240113/launcher-micromixin-4.0.0-a20240113.pom that is not the case for me, strangely enough. I wonder why that is the case?

[tender shard]

huh

?paste

[undone axle]

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

[tender shard]

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

this is m ypom

and it's exactly what ended up in the repo

very weird

[split lichen]

Does anyone have a recommendation for an NPC api/library which supports 1.20.4?

[tender shard]

citizens

[wet breach]

depends which light. The redstone itself changing is client side as that is just a change in the state of the redstone itself. As for the light it illuminates however that is server sided

[tender shard]

and here's the deployed version (the same, viewable in browser) https://repo.jeff-media.com/public/com/jeff-media/example-dependency-reduced/1.0/example-dependency-reduced-1.0.pom

[quiet ice]

Could it be my <shadedClassifierName>shaded</shadedClassifierName>?

[tender shard]

maybe, i added that so that it deploys both .jars

without that it'd only upload the shaded .jar

oh wait

yours

[quiet ice]

Yeah we both have the attached thingy

[tender shard]

I also used a shadedClassifierName before (i used with-dependencies) and it was the same result

really weird lol

[quiet ice]

23:52:37 [INFO] Installing /var/lib/jenkins/workspace/launcher-micromixin/dependency-reduced-pom.xml to /var/lib/jenkins/.m2/repository/org/stianloader/launcher-micromixin/4.0.0/launcher-micromixin-4.0.0.pom

The maven-install-plugin deploys the dependency-reduced-pom for me (see https://stianloader.org/jenkins/job/launcher-micromixin/13/console)

[tender shard]

that also happens when you set a shaded classifier name?

https://repo.jeff-media.com/#/public/com/jeff-media/example-dependency-reduced/1.1 i just deployed it again with a shadedClassifierName and it still only deploys the normal pom

[quiet ice]

have only tested with it

[tender shard]

for me it installs the normal pom???

this is so weird lol

[quiet ice]

Yeah I was about to say - what even is the point of the dependency-reduced pom if it doesn't show up in your repo?

[tender shard]

yeah that's what I'm also wondering

let me check sth quickly

[quiet ice]

Hm, I use maven-install-plugin 2.4 which is like age-old. Could be the issue? I'll see if I can update it

[tender shard]

https://repo.jeff-media.com/public/com/jeff-media/jefflib/jefflib/13.0.4/jefflib-13.0.4.pom
it also seems to upload the normal pom for all my other stuff (that all ahve dependencyReduced enabled). not just for this example project

but then, yeah, what's the point of that file if it's neither installed nor deployed

i'm using the default maven-install-plugin, 3.1.1 as of my mvn version

[quiet ice]

Me too, but I'd assume fedora is a bit outdated

Or well for some reason my CI server uses maven 3.8.6 which comes with version 2.4 while my system uses maven 3.9.1 which comes wtih version 3.1.0

Ah, that is because my CI server is on fedora 38 for whatever reason. Time to look how to update that.

well that starts of great

[tender shard]

🥲

[quiet ice]

Well for some reason I both have Adoptium and Zulu as installed repositories. I guess I'll just ditch the former (which I don't even remember having downloaded).

[tender shard]

since debian finally added adopt 17 in the official repo, I didnt have to mess with any repos for java anymore

[quiet ice]

I believe I have the azul zulu repo for Java 6

[inner mulch]

Hey I'm currently trying to track a whether a player is afk or not, that works fine so far, but when a player is afk and another player moves the player via pushing him, the playermoveevent triggers and tells the server the player isnt afk anymore, any suggestions?

[tender shard]

💀

[young knoll]

You could mess with disabling pushing for the afk player

[kindred sentinel]

Is there a boat move event?

[young knoll]

Or look for camera movement to consider them not afk

[quiet ice]

Yeah, for whatever ungodly reason people wanted a Java 6 port for one of my projects. Later on they wanted Java 5 but I said no until they can provide me an adequate JDK for that

[tender shard]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/vehicle/VehicleMoveEvent.html

[kindred sentinel]

Oh thanks

[inner mulch]

how do i track a cameramovement?

is there a specific event?

[young knoll]

The move event

Compare the pitch/yaw of the from and to locations

[inner mulch]

okay

thanks

[tender shard]

most reliable way is to listen to incoming ServerboundPlayerInputPacket and cnosider everything else to not be an actual movement

[inner mulch]

does this packet only register a players input?

[young knoll]

Yes

[sullen marlin]

Lol wat

[young knoll]

Please tell me the project is from 10 years ago

[quiet ice]

Well guess twice: It's the legacy modding community

[sullen marlin]

Pretty sure you can get literally anything to run java 8

[tender shard]

yeah it's what the client sends when a player moves (or jumps)

[sullen marlin]

Java 9 is where the issues start

[young knoll]

And people weren’t requesting java 6 support in modern times

[inner mulch]

there is probably no nice and easy event for this and i need protocollib right?

[quiet ice]

Nah, my project is from two years ago

[tender shard]

yeah protocollib would be easiest

[inner mulch]

okay

[quiet ice]

It's my wonderful micromixin library

[tender shard]

java 6 = 2006 = i was in 6th grade :X

[young knoll]

Project from 2022, java version from 2006

https://cdn.discordapp.com/emojis/1017515898870956154.gif?size=48&name=pepe_laugh&quality=lossless

[quiet ice]

At least I was born at that point in time

Also don't worry, it uses MRJ to make use of newer Java features where appropriate (why the hell did Java 6 not have Throwable#addSuppressed?)

[robust helm]

Regenerating griefed chunks after specific period of time

[sullen marlin]

Cause it is used from try with resources which java 6 didn't have

[quiet ice]

Ah, makes sense though

In the end I made my own very horrifying version of addSuppressed

[sullen marlin]

It's really just cosmetic ain't it?

[quiet ice]

Yeah, thankfully

[sullen marlin]

You could just throw the original exception without it?

[quiet ice]

It also includes a line telling the user to update their java - twice for good measure

[young knoll]

Man why doesn’t the Bukkit api work with java 6

[quiet ice]

I could also do a netty and say No further information. Update your java lol

[young knoll]

Encounter an unexpected error: It is not 2006

[tender shard]

and then craftbukkit even has the audacity to require java 17! what a shitty software!

[young knoll]

Ikr

[quiet ice]

@tender shard yep, same thing even with an updated version of maven. Wonders of technology - you don't even understand them

I'd hesitate a guess that it isn't me, it's you somehow.

[tender shard]

that's so cursed. I'm on maven 3.9.5 btw on mac. -but I doubt that makes a difference - would be very weird

[remote swallow]

that would be hilarious if it uses a different file for linux andm ac

[tender shard]

but then why does this happen for all my other libraries as well, both on mac and windows and over at least 3 different maven versions? o0

[sullen marlin]

Ye new maven broke / changed behaviour with dependency reduced pom and shaded artifact attached

That's why bukkit also has dependency reduced pom false now

It uses the dependency reduced pom for the main artifact, which makes no sense given the main artifact isn't shaded

[young knoll]

Should have used gradle

[remote swallow]

alex will convert to gradle

[sullen marlin]

I assume it's a bug but I'm not sure

[tender shard]

how can the maven version itself even have sth to do with this, it's the shade plugin that's solely reponsible for it, isnt it?

[quiet ice]

It isn't a bug from what I'd say

[sullen marlin]

I mean shade plugin I think

[quiet ice]

But it is behaviour that isn't great

[sullen marlin]

I think it is a bug cause it makes no sense otherwise

[remote swallow]

md if i were to learn gradle plugins properly would you make a special source plugin remapper offical

[quiet ice]

It has something to do with how default settings are set up under maven's XML ast

[sullen marlin]

I won't make it, you can

[remote swallow]

thats what i mean

if i made it would you make it offical

[tender shard]

gradle isn't even able to produce a proper pom.xml at all though

[sullen marlin]

Sure

[young knoll]

Shhh

[quiet ice]

No conditional setting defaults exist under maven that I am aware of

[young knoll]

No pom means no issues with pom

Big brain

[quiet ice]

How come so? I haven't seen any grave issues with it yet as long as you know what you are doing

[tender shard]

gradle's publish-maven plugin sets all dependencies that it decides to include in the pom to runtime scope iirc

[quiet ice]

Counter-example: https://stianloader.org/maven/de/geolykt/starloader-api/2.0.0-a20240108/

[quiet ice]

Well it uses compile for everything

[inner mulch]

im using protocollib and i'm listening to for a packet, depending on the packet call a custom event. Why do i get an error saying that i may only call my custom event synchronously even tho im not explicitly calling it async? Does calling an event in a packetlistener make it async or something?

[sullen marlin]

Probably

[young knoll]

Yes

[quiet ice]

However it does make sense once you know how a maven resolver works and these are the correct scopes

[remote swallow]

compile only is provided

[tender shard]

implementation -> runtime makes little sense imho

[sullen marlin]

You need to make your event Async (true to super constructor)

[young knoll]

By default packet listeners are async

[tender shard]

not for me. I have added those comments after I tested all those scopes

[quiet ice]

Well you wouldn't want it on the compile-time classpath of API consumers?

[inner mulch]

is there a detailed tutorial for the use of the event api, so i can look into this further?

[quiet ice]

Maven 3X sadly doesn't have a whole lot of scopes - but thankfully maven 4 will change that

[tender shard]

if it's implementation and I publish the shaded artifact, I don't want it to appear in the pom at all

[remote swallow]

?nms for me

[undone axle]

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

[tender shard]

and if I use api shouldn't it be provided?

[quiet ice]

oh yeah, it doesn't know about dependency-reduced poms or stuff

[quiet ice]

api stuff is still on the runtime classpath

[tender shard]

it uses some gradle-only file for this stuff IIRC, but ignores it for the pom

[tender shard]

well when I tried it, all api dependencies ended up as compile in the generated pom

on the other hand, gradle changes with every version, so I guess it might be different between gradle 8.3 and 9 and 7.X

i dont remember on which version I tested it but probably 9.0 or 8.3

[quiet ice]

Yeah - I have to agree that it isn't great, but I cannot really blame gradle for that as it just uses the best equivalent it can find

[tender shard]

yeah there's probably a gradle plugin that lets one specify what it should use for the pom for each dependency

[wet breach]

why would it need to produce one?

ultimately dependencies only need to be in the manifest

pom is handy I suppose if you want transitive dependencies

[tender shard]

yes, for this

anyway, i guess the proper way to get a working dependency-reduced pom for the shaded artifact, and a proper original pom for the unshaded artifact, is to set shadedArtifactId in the shade plugin instead of using a classifier

then one'd just have one artifact for the shaded version and one for the original one with their respective poms

[inner mulch]

im currently trying to find the packet do you know where i can find the protocollib's name?

[tender shard]

I can only tell you the proper (NMS) name: ServerboundPlayerInputPacket

the name on wiki.vg is Set Player Position

[inner mulch]

okay

i will look for it

[tender shard]

protocollib will be Play.Client.Something

Play.Client.POSITION

and Play.Client.POSITION_LOOK

POSITION is actually moving around and POSITION_LOOK is moving the head

@inner mulch

[wet breach]

Alex must be in a good mood

should consider yourself lucky 🙂

[tender shard]

why can't protocollib just use the mojang package names 🥲

[inner mulch]

thanks

[young knoll]

Yeah plib has weird names

[tender shard]

and wiki.vg also uses some made up names

[young knoll]

Probably because they are super old

[tender shard]

guess I'll have to create a list that maps mojang, wiki.vg and plib names

[young knoll]

I guess before mojmap you just had to make it up

[tender shard]

yeah true

but I wonder why there's no page that links all those names together

Set Player Position vs Play.Client.POSITION vs ServerboundPlayerInputPacket

totally different

[inner mulch]

im currently listening to Play.Client.POSITION and it is fired without the player moving?

[rare rover]

is this a good way to handle nms packet (to improve readability with your project):

i feel like its really nice

literally just this to send a hologram:

[dawn plover]

Hey everyone. I am trying to create a library with some cool functions so i dont have to copy them over everytime i am creating a new plugin
I currently did everything, (but then how i normally create a library) but it gives big time errors
So i was wondering. is there anyone here who created a library themselvs or knows of a library which i can see the source code of just so i can see how the gradle stuff is done for it
That would greatly help me if that was possible :)

[inner mulch]

                new PacketAdapter(CityBuildCore.getInstance(), ListenerPriority.NORMAL, PacketType.Play.Client.POSITION) {
                    @Override
                    public void onPacketReceiving(PacketEvent event) {
                        if (event.getPacketType() == PacketType.Play.Client.POSITION) {
                            //code
                        }
                    }
                }
        );```

[tender shard]

hm maybe it's not the right one? what I used to do to find out the protocollib name is to just print out ALL received packets's classes

[inner mulch]

oh thats smart

[tender shard]

you could e.g. listen to PlayerMoveEvent and print "player moved", then also print out all incoming packet class names, then check your log which packets appear shortly before "player moved"

and that should be the correct one

might also be that the POSITION packet is sent from time to time without them moving, in those cases the xxA and zzA fields probably both will be 0

[inner mulch]

oh that could be the reason

i guess i would need to check for changes too

[tender shard]

seems like both packets use the absolute coords and not just the moved distance

[inner mulch]

im currently checking and it seems like the POSITION packet is called every now and then

[tender shard]

yeah probably. you can probably just check whether the packet's X and Z (should always be getDoubles().get(0) and .get(2)) are the same as the player#s current X and Z, if yes they didnt move

[inner mulch]

if will try that

[tender shard]

although I'm only guessing all of this, I have no idea if any of this is true lol

[inner mulch]

its okay, i guess its time to find out

(for me)

[alpine urchin]

just as general info on wiki vg

in this case the data types have to align with the protocollib ones

but wiki vg is based on the data type in the actual buffer

so in some cases wiki vg might claim something to be a byte whilst minecraft inside nms represents it with an int

so sometimes people run into issues and get confused, just know wiki vg isn’t exactly documenting NMS

[limber mantle]

hi, i have kinda a complex problem with packets. idk where else to turn to. i run a server with a magic plugin that creates a good amount of particles. this used to be manageable, but at some point they got unmanageable at higher player counts. the type of lag i see is not one that spark can easily track; the tps doesn't go down and the server thread seems to be in good health (see example). instead what happens is the ping gets very high, people start 'teleporting' around, and eventually some of them are kicked due to timeout (but not all) and the server never crashes, but other plugins like discordsrv get bogged down and miss their scheduled tasks that are on different threads. someone called this network overload, and after some testing, i confirmed it is worsened by more of these particles. however this wasn't always a problem, and the magic plugin hasn't changed. i think another plugin is duplicating/copying packets or something and overloading the network, but i'm at a loss for how to track these particle packets to find the source of the problem. i was wondering if there's a way to track them. i have protocollib and i figured another plugin is messing with that, but when i debugged all the packet listeners, none of them had to do with particles. any help would be appreciated

[alpine urchin]

tldr

since it has packets ill give it a look XD

[limber mantle]

is there a good way to track all packets

specifically worldparticles packets

bc i think there's a plugin doing weird shit with them and overloading my network

[alpine urchin]

yeah im not reading ur wssay

i dont want to self advertise

so

but there’s alternatives to protoxollib

just so you know

[limber mantle]

the 'essay' is there so ppl would respond with things i didn't already know, no offense

[alpine urchin]

you were talkijg about load

and etc

so i said there’s alternatives

[limber mantle]

this was my tldr

[alpine urchin]

yes

do you mean in protocollib specifically?

[limber mantle]

in general

[alpine urchin]

yes? theres libraries that do that

[limber mantle]

such as?

[alpine urchin]

can’t say

or else its self advertising

[remote swallow]

anyone know any decent jda modal util thing

[hazy parrot]

jda ktx only

but its kotlin

everything other is outdated afaik

[limber mantle]

how would i track packets with packetevents

like if a plugin were somehow manipulating packets

would i be able to determine which

[tender shard]

you mean those "forms" in discord?

[hazy parrot]

yeah those are modals

[remote swallow]

ya

[tender shard]

what's wrong with JDA's builtin stuff?

[remote swallow]

its long

i have 15 lines for a 4 entry modal

and thats with it going through a small util method

[tender shard]

hm idk I always only use JDA 5

[remote swallow]

im also using jda 5

[tender shard]

the example in their javadocs doesn't look too bad though?

[alpine urchin]

okay that’s a different question than the tldr

[remote swallow]

its long and i dont want like 10 lines for a 2 entry modal

[limber mantle]

it was in the 'essay' you didn't want to read

[alpine urchin]

if they’re not using packetevents then you can’t specifically check what changes they made

[limber mantle]

the reason i want to track packets is bc i think a plugin is manipulating them and causing overload

[alpine urchin]

find out

which plugin itnis

and then we can move on and look intobwhy

thats the best approach

this is kind of an

?xy

[undone axle]

http://xyproblem.info/

[limber mantle]

it's kinda more complicated than that

anyway

ty for the help

not rly tho

[alpine urchin]

if you find out which packet plugin

is causing this load

we can look intonit

and move on

but if you want to do it your own way go ahead

[quiet ice]

@aztl in the worst case you could use ignite and mixin into the relevant packet classes and see if there is suspicious activity from there. Injecting into the netty pipeline would be another way to go about this. Regardless this is a rather complicated problem as you stated earlier and I suppose I am of not much better help (especially given that such diagnostics will probably take a while), but those would be the ideas I'd have from the first go.

Ah bruh they seriously left

Well - their loss

[river oracle]

So right now I have a map that does something and uses a class as a key. However I ran into a bit of an issue. Because the craft classes aren't in this map all of the keys will return null. e.g. org.bukkit.craftbukkit.v1_20_R3.inventory.CraftShapedRecipe inherits, but isn't org.bukkit.inventory.ShapedRecipe

[kind hatch]

Isn't that where generics can come in?

[river oracle]

is there any way to get around this or should I just make my own data structure for this

[river oracle]

not super useful here

it's the key so how would I express that type in the key

        this.functions = new HashMap<>();
        functions.put(ShapedRecipe.class, new ShapedUncrafter());
        functions.put(ShapelessRecipe.class, new ShapelessUncrafter());

[young knoll]

It’s possible to extract the Bukkit interface from the impl class

[river oracle]

guh that's annoying my own data structure it is ig I wonder if I can actually get O(1) probably not huh

[young knoll]

¯_(ツ)_/¯

[river oracle]

prolly just an ArrayList with a loop then of Class#isAssignable

[quiet ice]

You might get away getting the interfaces that a class implements but that is hacky his grandfather (as some Germans would say 😉)

[young knoll]

You don’t want to use Class.getInterfaces?

[river oracle]

I mean I could

but then I have to loop over every interface anyway

isAssignable is probably just as effective here

[young knoll]

There shouldn’t be many

But yeah

[quiet ice]

Or just assume it is the length of 1

[river oracle]

that's dangerous with CB

[quiet ice]

Pft

[young knoll]

Me omw to add more interfaces to the recipe impls

[quiet ice]

But why?

[young knoll]

Fun

[tender shard]

ShapedRecipe already extends CraftingRecipe

[river oracle]

I mean I just realized this wouldn't even be very good because I'd need to do a map#get call on every interface

[young knoll]

Yes but that isn’t the impl

CraftShapedRecipe or whatever should only implement ShapedRecipe

[quiet ice]

Yeah, but it shouldn't get the super-interfaces

[tender shard]

oh wait, I thought ShapedRecipe and CraftingRecipe would be interfaces

they're not

[river oracle]

mmmmmm

well not every recipe is guarenteed to be Craft though

that's the thing

so either way its to map calls ig

[young knoll]

Oh wait

Is it like itemstack

[river oracle]

I could actually cheat here

and insert them into the map

after one run

[tender shard]

is hacky his grandfather
erm what? 😄

[quiet ice]

"X sein Großvater" - never heard that?

[young knoll]

Ugh it is kinda like ItemStack

Where there is a Bukkit and CraftBukkit version

Blah

[tender shard]

never lol

[quiet ice]

Well now you did

[tender shard]

thanks!

[quiet ice]

Probably is an Odenwald thing then

[river oracle]

@young knoll I've decided I'm kinda gonna use your idea. On the first run I'm going to iterate and find it's bukkit type and then cheat and add it to the map after it's run once so it never has to do a calculation for that type again

[young knoll]

Fair

Or you could add the Bukkit types manually :p

[quiet ice]

Anyways use my genius "ClassWrapper" API to cache isAssignableFrom on the fly for maximum performance!

Well probably a bit overkill since you don't want to compute the frames of classes

[young knoll]

Ah wait you do do that

Yeah I see

Convert Pitch and Yaw to Quaternion

[tribal quarry]

Sorry, I might be wrong, but I haven't found weakhashset that acts like queues, but there might be some weak queues or weak arraylists in java or other utils.

[hoary light]

Oh tysm! It work!

[sterile token]

Suppose you are planning the design of a command framework system. And you have to think about how to structure the classes taking into account that there may be commands that have no arguments and commands that contain sub-commands. But arriving at a final result where you would have to be able to support commands in tree format, how would you design it?

[quaint mantle]

Similar to bukkit's ConfigurationSection

Make it so we could create an instance of a VeranoCommand (or whatever name you wish), then we could call getArg(String arg)

[sterile token]

oh allright, something like a Command class with common things and 2 implementations, one for commands which dont have any direct association like a health command and compose one, like /faction which has many arguments and sub commands as childs

Like how a n tree works

[quaint mantle]

Inside getArg, it would check if String[] args length is enough

If not, it returns null

[sterile token]

yes i know all how to design it. But i have some issues withing childs of childs

[quaint mantle]

Else it would return a CommandSection (or whatever you wish to name)

[sterile token]

Are you current free? Maybe i can ask specific questions

[quaint mantle]

That CommandSection would also track the length of String[] args in case the dev wishes to do getArg(String arg) again

[quaint mantle]

As of passing it on constructor

[undone moon]

HI
how to send data from plugin to plugin

[tame wolf]

?xy

[undone axle]

http://xyproblem.info/

[mighty crane]

Hello!
Is there a way to 'convert' a set of commands into plugin code?
(I want to 'convert' these for example: /summon armor_stand -227.50 74.00 -15.50 {Silent:1b,Small:1b,Invisible:1b,NoBasePlate:1b,Motion:[-4.5,2.0,0.15],Tags:["travel"]} and after that /ride {player} mount {the armor stand})

[minor junco]

No idea what you mean with converting commands to plugin code

[wet breach]

this is easy to do

[undone moon]

ok how

[wet breach]

Well there is numerous ways you can do this

from the intuitive to the very archaic of ways

[lost matrix]

There is not really a special way of "sending data from plugin to plugin" because all plugins
are loaded by the same classloader in the same jvm, meaning you have access to all the data of all plugins.
However, if you want to notify other plugins about special functionality being executed, then you can simply
implement a new Event and fire it. Other plugins can subscribe to them.

[shadow night]

I've recently tried using javalin in a spigot plugin and I had some error, I found out from a gh issue it's due to the modified classloader or whatever. Can somebody explain what that means and why that could possibly break a library

[minor junco]

💀

[lost matrix]

I mean, you can write some code that achieves exactly the same.
But there is no way to automatically convert a command to code. There are thousands of different ways
to write code that results in the same functionality.

[minor junco]

Have your receiver be the dependency of the sender and interact with a common interface

[wet breach]

thre isn't a single class loader in the JVM, while it is true there is a singular classloader that all others derive from, this doesn't mean two classloaders below it are equal

so something in one classloader doesn't automatically mean it is discoverable by another

unless its a parent or a child then most times it is

[shadow night]

Hmm

[wet breach]

the only thing that is important is as long as the JVM can find it, not that other things in the JVM can find it

there are methods however to find something in another classloader, its just not automatic is all

[lost matrix]

Are you sure that this is a javelin problem?
Because this problem usually occurs for CDI frameworks which use classpath scanning
for its dependency injection.

[shadow night]

No idea, but I found some description of that issue on their github. It's something about classloaders and the solution is just switching the classloader to the classes one and then switching it back

[wet breach]

how exactly is javalin obtained?

are you shading it?

[shadow night]

Yeah

Or more like shadowing it because for some reason I decided to go with gradle

[wet breach]

then there is a dependency it needs access to that for whatever reason isn't being accessible from the plugin loader

[wet breach]

idk what javalin does, but what error are you getting though?

[dry hazel]

it just seems that javalin/jetty uses the current thread's context class loader to search for something and that doesn't have the dep, so you temporarily have to swap it with your plugin's one for instantiation

[shadow night]

The one that the github issue shows in that codeblock, something about a websocket thingy class missing or something

[wet breach]

it doesn't show the error

not sure how you are expect me to know what java.lang.run refers to when its not complete

[shadow night]

I don't remember if I had the exact same error, but I think yes

[ERROR] java.lang.RuntimeException: javax.servlet.ServletException: java.lang.RuntimeException: Unable to load org.eclipse.jetty.websocket.server.WebSocketServerFactory
        ...
Caused by: java.lang.ClassNotFoundException: org.eclipse.jetty.websocket.server.WebSocketServerFactory```

[wet breach]

and this class is present in your project?

[upper hazel]

what is the best event option to choose to impose an effect on a player if there is a certain item in his main hand?

[shadow night]

No idea, didn't try looking it up, but it worked fine in a standalone app

[shadow night]

But ig this sounds like an explanation

[dry hazel]

the javalin people blogged about it https://javalin.io/tutorials/javalin-and-minecraft-servers

not sure why it uses the context class loader in the first place though

[wet breach]

Which seems unnecessary though if its a library. Why would it need to search for something that is supposed to be contained in the project already? Only thing I can think of is if its trying to find a JVM lib instead

which also makes sense

the easy solution if its a JVM lib, is to see if said lib can just be included as well 🙂

sometimes jvm libs have alternative libs to be used in projects instead

since you can't guarantee the JVM environment your application will run in

[shadow night]

Reminds me of doing C, you have to make fifty different same functions that work on different platforms

[wet breach]

well at least with java its just that not all JDK's are equal

[shadow night]

Luckily

[wet breach]

even if they are, not everyone sets up their environments the same

[shadow night]

You can set it up differently?

[dry hazel]

to me it seems like it's just searching for implementations of a class using ServiceLoader or something similar

[wet breach]

you can exclude JVM libs arbitrarily

or you can add

just because there is default ones doesn't mean these are concrete

There is System Libs and User libs too

system libs are included in the JVM regardless of the user, where as user ones depends which user invoked java

[shadow night]

I love java for not forcing me to make three different implementations of the same function because of os differences

[wet breach]

lol

anyways, probably worth though figuring out what is its trying to find

seems a bit short sighted on the developers part that they make use of the class loader to do some kind of searching

knowing its error prone

[shadow night]

But it has probably been patched in newer javalin versions, I just need to support java8 lol

[wet breach]

oh that could be

[dry hazel]

well searching for services is common for example, but it's on them or one of their dependencies that it uses the context class loader for whatever reason

[wet breach]

Don't you just love this discord

can always learn something new 🙂

[shadow night]

Yeah, especially when I can't work on a plugin I enjoy...

[dry hazel]

never read a timings report if you're asking that

[wet breach]

if you had paid attention to the conversation or just scroll up, the solution(s) should be fairly obvious

[proper cosmos]

Hello, guys. I have this code for getting EntityType from String. java EntityType mob = Arrays.stream(EntityType.values()) .filter(EntityType::isSpawnable) .filter(e -> e.name().equalsIgnoreCase(item.getMessage().replaceAll(" ", "_"))).findAny().orElse(null);

And I only want to get passive mobs

[sullen marlin]

Probably then filter EntityType#getEntityClass isAssignableFrom(Mob.class)?

Or Creature.class

[proper cosmos]

Ye, already got it. But thanks

[tribal valve]

i want to make so that the player can't destroy map blocks, and idk if i should like get all of the blocks on start and check if desteoyed block is inside a list of map blocks or if i should make a list at the start of the game that contains all of the blocks player placed

[proper cosmos]

I don't know if there's method in SpigotAPI, but if there wouldn't be I would just listen for playerPlacedBlock and add it to list then listen to playerDestroyBlock and check if list contains this block if not cancel. Idk if searching through list with huge amount of objects would cause performance issues but ye

or adding nbt data to block

[shadow night]

I had a plugin like that

[tribal valve]

im just wondering about performace, if like 8/16 players would just crash the server by placing blocks so much and destroying them real fast, the list would probably store about 2k blocks

so yea im just wondering about performace

[proper cosmos]

ye that's the problem

so you can add nbt data/ persistant data (depends if you want to remeber blocks after restart)

[shadow night]

hmm

[tribal valve]

wouldnt that be removed on block place?

[proper cosmos]

wdym

[tribal valve]

nah i dont, im making bedwars like plugin

[proper cosmos]

so setting metaData to block would be good

or just check how other popular bedwars plugins do it

[tribal valve]

okay ill check thanks

He's using LinkedList of bukkit.Vectors

[upper hazel]

What is the best way to save hash data to a file when the plugin is turned off or immediately ?

or do autosave

[proper cosmos]

As far as i know there's no way to save if server crashed or force closed

but if you want to save on normal stop

[shadow night]

that looks like you need to use a database

[upper hazel]

what is the safest option

[proper cosmos]

just saveConfig onDisable

[proper cosmos]

^

[upper hazel]

i not can i need file

[shadow night]

what

[proper cosmos]

just saveConfig onDisable, and if you are aware of crashes, just save your config every 30 seconds smth like that using bukkit scheduler

[upper hazel]

I was told to put it in a file.

[proper cosmos]

but as RaydanOMG said you should use database

[upper hazel]

ok

i gess autosave this best option

[proper cosmos]

And why you using String as money

Just use Integer

[shadow night]

or in case your economy is a bit fucked a long

this was scheme

i use double 👍

hi, I would like to add a store system to my plugin (with inventories) with submenus for individual categories ecc. What would be my options to implement this, or is there a library that can help me?

[chrome beacon]

There are plenty of inventory libraries to choose from

IF, InventoryGui and InvUI just to name a few

[hazy parrot]

sqlite is file based

[proud badge]

if I have some objects with strings that should be empty/not exist, would it be better to use "" or just null?

[next plume]

Empty and not exist are two different things.
In general, use "" for empty and null for non-existent.

[wet breach]

this is redundant

statistics track this

just pull the info from there

or I at least I am pretty sure it does

[tender shard]

you probably have to set back the item into the inventory

[ornate heart]

This has probably been asked a lot but does World#hasStorm guarantee that it's raining if it returns true?

and if not, how could I figure out if it's raining?

[agile hollow]

if i want make a public method for an item how i have to do it?

[tender shard]

whether it's raining or not depends on the biome

[tender shard]

?

[agile hollow]

i want to get an item everytime with the same name etc and for that i put it in a method but what method?

[tender shard]

public ItemStack getMyItem() {
  return myItemStack;
}

??

[agile hollow]

smth like that u mean?

      ItemStack freeze = getItem(new ItemStack(Material.ICE), "&aFreeze", "&aQuesto Item ti permettera' di freezare la persuna su cui farai tasto destro!");
      return freeze;
    }```?

[shadow night]

If I get an instance of an itemstack and put it in two different inventories, will it still be considered the same itemstack and be linked like using an update suppressor or does bukkit do something against

[tender shard]

no, you should store that itemstack in a field instead of recreating it everytime

[agile hollow]

how that's my problem

because you add 0.1 to the rotation every tick

But that is'nt the width and height right?

[tender shard]

https://misode.github.io/transformation/ click the "unlock" button for leftRotation, then you can see what you're doing

Hello, quick question, I want to create a plugin on minecraft in java, and I ask myself the following question, how to communicate with my database?
Is there an ORM like EF in C#?
Should I do my sql queries manually and convert them to java obj?
Is there a lib that allows me to map my SQL requests directly to my objs?

What do you advice me ?

[upper hazel]

multimap work with "for" correct?

[tender shard]

ORMLite maybe?

[tender shard]

Multimap itself is not Iterable but you can get a Collection<Entry<K,V>> with Multimap#entries()

[minor ivy]

If you had to make a plugin that uses a database, would you use it?

[upper hazel]

so this will not work?

[eternal night]

forEach != for-each loop

[tender shard]

i never used it but I also avoid sql as much as possible

[upper hazel]

really?

[eternal night]

yes

.forEach will work as you'd expect

for(Entry<String, String> entry : multiMap) will not compile

[upper hazel]

how will it work in this case? what is it like - key->value, key-value2, key2-value, key2-value2 ?

in 1 step

[eternal night]

Performs the given action for all key-value pairs contained in this multimap. If an ordering is specified by the Multimap implementation, actions will be performed in the order of iteration of entries(). Exceptions thrown by the action are relayed to the caller.
To loop over all keys and their associated value collections, write Multimaps.asMap(multimap).forEach((key, valueCollection) -> action()).#

[agile hollow]

i done smth like that

    public static ItemStack getFreezeItem() {
        return freezeItem;
    }

    private static ItemStack createFreezeItem() {
        return getItem(new ItemStack(Material.ICE), "&aFreeze", "&aQuesto Item ti permettera' di freezare la persona su cui farai tasto destro!");
    }```
but i'm getting nothing when i do smth like that:
```            if(player.getInventory().contains(Inventories.getFreezeItem())) {
                player.getInventory().remove(Inventories.getFreezeItem());
               
            }```

[shadow night]

I think you don't need to check contains when removing stuff

[agile hollow]

but if the player doesn't have that stuff?

[shadow night]

remove should check that, atleast that's what ij always tells me

[ornate heart]

Any easy way to decipher whether it's a rainable biome?

[elder harness]

Is it a known issue that from time to time plugins throw a "NoSuchMethodException" on some types? A reload "fixes" the issue, but I have never known what is causing it to happen

[eternal night]

don't replace your jar at runtime. Reloads are a pretty nasty concept.

[elder harness]

Thank you. That is probably it :p

[elder harness]

Yea, but if I would reboot rather than restart, it would have taken hours of my life at this point 💀

[eternal night]

you can look into hot-swapping

[shadow night]

I just run older versions cuz they load fast 💀

[elder harness]

Hot swapping, meaning only building files with detected changes?

That wouldn't make much sense when you build a .jar that is a single file on itself

[shadow night]

Hot swapping is when you replace class files afaik

[eternal night]

there are certain jvms out there that you can hot-swap class in

lemme see if I can find you the article

[hushed spindle]

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

[wary harness]

this just looks beautiful

[hushed spindle]

so i often get an exception like this
https://paste.md-5.net/ajonoxejil.bash
which happens in a consistent but strange way. i have custom guis in my plugin and the error occurs when i join a server, open a gui, leave and rejoin the server, and then open up a gui again
as far as I can tell CancelledPacketHandleException occurs when a packet is sent to the player asynchronously, but as far as i know i'm not doing that. a couple guis are building items asynchronously and then inserting them into the menu with a callback, but it happens to any gui and not just those
any idea how i could go about finding out where i'm apparently sending a packet async?

[minor junco]

You could also just create placeholder line(s) that automatically are aggregated and populated with each descriptive command node there is. And additionally (programmatically) create key / value pairs in your configuration being the description of each command

That makes things a lot better but so do you

[inner mulch]

is a base64 decoder the best for saving inventory contents in a db, or is there another approach?

[eternal night]

I mean, most DBs should just support plain binary ?

[inner mulch]

so i should convert the inventory into binary?

[eternal night]

Well depends on how you serialise your inventory

[inner mulch]

im currently not really doing anything with the inventory

[echo basalt]

The popular approach is to just use the bkkit object output stream

[minor junco]

you can serialize it to an object output stream and push that to the database no? If your database doesn't support that you could add some kind of adapter that handles the underlying conversion / queries

[echo basalt]

Which is nice in my case because I just wrote a system to convert between multiple inventory sync projects

[inner mulch]

so, whats the bkkit object output stream, can you provide an example or a ressource so i can get more into this?

[chrome beacon]

You call setSize on it

[chrome beacon]

That's not how you cast and call a method on one line

[spare hazel]

oh i fixed it

[plucky skiff]

I have this code:

    @EventHandler
    public void onItemSwap(PlayerItemHeldEvent event) {

        Player player = event.getPlayer();

        if (!isActivated.contains(player.getUniqueId())) return;

        event.setCancelled(true);

        for(Player onlinePlayer : Bukkit.getOnlinePlayers()) {

            if (onlinePlayer.getUniqueId() == player.getUniqueId()) continue;
            onlinePlayer.sendEquipmentChange(player, EquipmentSlot.HAND, event.getPlayer().getInventory().getItemInMainHand());

        }

        player.getInventory().setHeldItemSlot(event.getNewSlot());

        for(Player onlinePlayer : Bukkit.getOnlinePlayers()) {

            if (onlinePlayer.getUniqueId() == player.getUniqueId()) continue;
            onlinePlayer.sendEquipmentChange(player, EquipmentSlot.HAND, new ItemStack(Material.AIR))

        }
}

And it's supposed to make the item invisible on item swap if it is activate. But for some reason, it does activate, it does get the players, but it doesn't send the equipment change packet...
I cancel the event because I need to make that happen after the slot has been changed, so I change it myself, since the PlayerItemHeldEvent happens before you switch an item.

Does anyone know why it doesn't work?

    }

am i doing this right? i want it to be an effect that moves and then dies

[chrome beacon]

If you want to modify a spawned entity used the spawn method that accepts a consumer

That way it can be spawned with the settings you want instead of spawned and then modified

[spare hazel]

how can i kill an entity

[chrome beacon]

Call remove on it

[chrome beacon]

so what exactly is the goal here

[lost matrix]

Killing -> set its health to 0
Removing from the game -> call .remove() on it

[spare hazel]

alr thanks

how can i check to see if the entity is removed or not

[chrome beacon]

Try isDead or isValid

[spare hazel]

i spawned a magmacube with 10K health but it spawns with 50 health

why

[echo basalt]

Attribute modifiers or something idk I'm not a magma cube

[hushed spindle]

did you heal it yet

[spare hazel]

hmmm

how

[hushed spindle]

setting max health to 10k doesnt set current health to 10k

LivingEntity#setHealth() lol

[spare hazel]

public void setEntityStats(LivingEntity entity){
        entity.getAttribute(Attribute.GENERIC_ARMOR).setBaseValue(sDefense);
        entity.getAttribute(Attribute.GENERIC_MAX_HEALTH).setBaseValue(sHealth);
        entity.getAttribute(Attribute.GENERIC_MAX_HEALTH).setBaseValue(sHealth);
        entity.setHealth(sHealth);
        try{entity.getAttribute(Attribute.GENERIC_ATTACK_DAMAGE).setBaseValue(sDamage);}catch(Exception ignore){}
        entity.getAttribute(Attribute.GENERIC_MOVEMENT_SPEED).setBaseValue(sSpeed);
    }

heres what i did

[hushed spindle]

why are you setting generic max health twice

[spare hazel]

was an accident

before a hit

[echo basalt]

yet another hypixel skyblock copy

[eternal night]

[hushed spindle]

classic

and what are you using to display their health like that

[echo basalt]

setDisplayName

[hushed spindle]

ok no shit lol

what about their health

are you doing getHealth or their health attribute

and are you updating it after it takes damage

[mighty crane]

Is it possible to execute a piece of code when a player enters a defined space?

if yes, how?

[eternal night]

Well, if you have stuff like world guard, there are events for that

if you don't you end up basically having to check either on PlayerMove or every tick if a player is in the area you defined

[mighty crane]

oh rip

[hushed spindle]

seems overkill

i often get this error
https://paste.md-5.net/ajonoxejil.bash
and it indicates the player is sent a packet asynchronously, but how can i figure out where that's happening?

[eternal night]

is that the entire stacktrace ?

[hushed spindle]

yup

theres no reference to my code

hence why its hard to find

it specifically happens with custom inventories if that matters

[eternal night]

Well I expected it to at least have some context on where the "CancelledPacketHandleException" is thrown but rip

[gritty lake]

Hi

How can i reforward command from bungee to server? for 1.19+ clients?
Like sc.unsafe().sendPacket((DefinedPacket) new Chat(e.getMessage())); no longer work it kicks the player but works fine for below 1.19

So now i tried
sc.unsafe().sendPacket( new SystemChat(e.getMessage(), ChatMessageType.SYSTEM.ordinal() ) ); but that does not work either :S i see bungeecord use systemchat

[hushed spindle]

ive been pondering this bug for a week now lol

[eternal night]

Well I mean, ValhallaMMO seems closed source so I guess not much to look at ?

[hushed spindle]

its open

[eternal night]

link pls

[hushed spindle]

https://github.com/Athlaeos/ValhallaMMO

[eternal night]

not linked on their spigot page

merci

[hushed spindle]

oh i didnt? fuck

[plucky skiff]

ah yes, I explained it there but alr. It's supposed to make the item the player is currently holding invisible by fake packets to all the players every time a player changes item in the hand

[mighty crane]

How would I do that with worldguard?

[hushed spindle]

also my apologies in advance for the horror you will face in this repo

[eternal night]

is this replicable ?

like, can I replicate that by just downloading the plugin and running /skills

the stacktrace indeed does not give much

[hushed spindle]

its very replicable, though the version on spigot isnt whats on github

its a rewrite

[eternal night]

oh

well

[hushed spindle]

but it specifically only happens when someone joins, opens a gui, leaves and joins, and opens a gui again

which is like ???????????

so you're basically not allowed to relog

thought that maybe its because some guis build their items asynchronously and populate the menu with a callback but making it all sync again didnt resolve it

[eternal night]

👀

[hushed spindle]

thought that it might also be with some packet listening which is also async, but removing that also didnt work

[quaint mantle]

so I am very new but am just trying to make a simple plugin that will send me to my hub server, I have a test command which works but I am just confused on why my server is saying that i am using a legacy plugin.
[09:34:26 WARN]: [org.bukkit.craftbukkit.v1_20_R1.legacy.CraftLegacy] Initializing Legacy Material Support. Unless you have legacy plugins and/or data this is a bug!
[09:34:27 WARN]: Legacy plugin first_plugin v0.0.6 does not specify an api-version.
it says I do not specify a api-version but I do https://pastebin.com/7unzGrW8 any ideas on the stupid mistake I made?

[echo basalt]

gui population can be done async iirc

[hushed spindle]

could it be because im using InventoryHolder for the custom guis

because i know thats a sin lol

[echo basalt]

ew

I looked into it

Basically all vanilla inventories copy the entire holder when you call getHolder

And that in turn copies the entire inv

There is no problem when the check passes, it's when it fails that's the problem

[hushed spindle]

i understand why its a sin but its like a relic of the past when i didnt know any better and i just havent gotten around to improving that

still shouldnt be throwing CancelledPacketHandleException though right

[eternal night]

I mean, probably easiest for you would be to just attach a debugger and go for it

[iron cave]

Should be api-version not api

[hushed spindle]

debug how

[eternal night]

like, intellij debugger

[hushed spindle]

ive already checked if the gui is being opened async and its not

[quaint mantle]

tysm

[eternal night]

throw a breakpoint

[hushed spindle]

wait you can do that with plugins?

[eternal night]

yea ?

o.O

[hushed spindle]

how do you do that, you cant run plugins just like that can you

[eternal night]

the thing that is basically fucking you is PacketUtils.ensureRunningOnSameThread(packet, this, this.player.serverLevel())

well you start the server with the flags

that IJ provides

and then you just attach

like, you add -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:5005 to the start script

and then you can do a normal remote jvm debug configuration

¯_(ツ)_/¯

[hushed spindle]

oh shit

how's nobody told me that in 4 years

[eternal night]

issue is, server mappings will fuck you

[quaint mantle]

woah

[eternal night]

so like, you cannot jump into the server code to see what happens

https://docs.papermc.io/paper/dev/debugging#setting-up-the-debugger

if you want a tutorial to forllow

additionally, add -Ddisable.watchdog to your startup to disable the watchdog

otherwise your server will kill itself after like 10 seconds of the main thread being stuck at your break point

[hushed spindle]

thats rad

now the question is where the hell do i put my break point lol

my code wasnt referenced at all

[quaint mantle]

when i change it to api-version it throws this error in the server console https://pastebin.com/rFzeCw1w
and in vscode it also give an error saying this, but it says the error is at 1:1
Missing property "api".yaml-schema: PocketMine plugin.yml
Bukkit plugin.yml
The unique name of plugin.
Source: plugin.yml

[eternal night]

I'd just smack it on top of your skills command and then step over

[hushed spindle]

ill see if that does anything

[iron cave]

should only be the major version, so use '1.15'

You don't need the extra 0

[quaint mantle]

that worked, ty

i did a test and it seems like the entity's health is 43 when it spawns

[mighty crane]

I'm guessing this will create a lot of lag?

public class PlayerMoveEventListener implements Listener {

    @EventHandler
    public void onPlayerMoveEvent(PlayerMoveEvent event) {
        if (event.hasChangedBlock()) {
            Player player = event.getPlayer();
            Location to = event.getTo();
            if (to.getBlockX() >= -225 && to.getBlockX() <= -223 && to.getBlockY() >= 73 && to.getBlockY() <= 77 && to.getBlockZ() >= -16 && to.getBlockZ() <= -14) {
                //code
            }
        }
    }
}

[lunar wigeon]

no

[mighty crane]

oh ok

[hushed spindle]

it literally jumps straight to the error the moment it gets to the menu creation part, like it doesnt even step through the gui constructor or the open() method

do you know what i can do with that lol

straight to this

[minor junco]

Why should this? You're basically just performing value comparisons

[shadow night]

Isn't gonna do a lot

[hushed spindle]

ah actually i just had to put break points in those methods too, didnt realize that

exception is thrown at Player#openInventory() it seems

which i guess would be the packet thats apparently sent async

[mighty crane]

because it checs every single time i (or another player) move

[minor junco]

I mean on a nanosecond scale (maybe even millisecond) it will definitely have a performance "impact", but that just counts to premature optimization

Build the thing first and test your performance after with whatever you're doing there

[mighty crane]

oh alr

[plucky skiff]

I have this code (not full):

    @EventHandler
    public void onItemInteract(PlayerInteractEvent event) {
    
        Player player = event.getPlayer();

        ProtocolLibrary.getProtocolManager()
            .addPacketListener(new PacketAdapter(ShardPlugin.getPlugin(), PacketType.Play.Server.ENTITY_EQUIPMENT) {
                @Override
                public void onPacketSending(PacketEvent event) {
                    if (!isActivated.contains(player.getUniqueId())) return;

                    for(Player onlinePlayer : Bukkit.getOnlinePlayers()) {

                        if (onlinePlayer.getUniqueId() == player.getUniqueId()) continue;
                        onlinePlayer.sendEquipmentChange(player, EquipmentSlot.HAND, new ItemStack(Material.AIR));
                        onlinePlayer.sendEquipmentChange(player, EquipmentSlot.HEAD, new ItemStack(Material.AIR));
                        onlinePlayer.sendEquipmentChange(player, EquipmentSlot.CHEST, new ItemStack(Material.AIR));
                        onlinePlayer.sendEquipmentChange(player, EquipmentSlot.LEGS, new ItemStack(Material.AIR));
                        onlinePlayer.sendEquipmentChange(player, EquipmentSlot.FEET, new ItemStack(Material.AIR));

                    }
                }
            });

    }

And that creates a java.lang.StackOverflowError.

onlinePlayer.sendEquipmentChange(player, EquipmentSlot.HAND, new ItemStack(Material.AIR));
And it get's generated in this line ↑

Any idea why?

[mighty crane]

please add java after ```

(makes it easier to read)

[plucky skiff]

ah ok

[minor junco]

Erm you shouldn't add packet listeners in (such) an event to begin with

[plucky skiff]

yeah though that, but where should I put it then

[minor junco]

Do it on plugin load up

[hushed spindle]

you only want to register one of those listeners

[plucky skiff]

and create a method to get the isActivated method?

[hushed spindle]

doing it on every interact event is gonna blow that the fuck up

[minor junco]

is activated doesn't seem to be a method

[plucky skiff]

I mean variable

private List<UUID> isActivated = new ArrayList<>();

[minor junco]

I guess so, if you want to stick to this desigm

[plucky skiff]

what other options are there then?

[minor junco]

Use a set please, instead of a list unless you allow duplicates. Your lookup will be O(n) in worst case whereas a hash set has constant lookup

But you have other issues with sets so

[minor junco]

I mean I can't type them out rn I'm on my phone

But you can do it like that yeah, if you want to stick to this make it static or use a static getter or whatever, but I recommend anything else but that

[plucky skiff]

ah ok

[hoary light]

How I'm can use 5 size like hopper? But minimal it 9.
Someone know how do it?

Inventory inventory = ((Hopper) block.getState()).getInventory();
Inventory ui = Bukkit.createInventory(null, 9, UIname);
ui.setContents(inventory.getContents());

[echo basalt]

InventoryType.HOPPER

[plucky skiff]

even if I put it in an onEnable() method, it still throws a java.lang.StackOverflowError

does anyone have an idea here ↑

[hoary light]

Oh tysm!

[minor junco]

I mean what is happening is that you receive the entity equipment packet and then send another one, triggering this method to be executed again

you could fix this by putting every player that you send it to in a Set (for example your isActivated) and do not send any more equipment changes when a player is within that set

@plucky skiff

[plucky skiff]

well what I want is to make the player items invis if it is activated, now I'm actually getting this weird error for some reason: java.lang.NullPointerException: plugin cannot be NULL. which doesn't make sense since it shouldn't be null

[minor junco]

well debug when your plugin is null and when it is updated

whereever this exception is thrown

[plucky skiff]

can I send my code?

[tender shard]

is the file saved as UTF8, did you set maen/gradle to compile as UTF8, and did you also load the file using UTF8?

[wary harness]

is this not loaded as utf-8

[tender shard]

it is

so is the file saved as UTF8?

and did you set the compiler options?

[tender shard]

it's great though

[agile hollow]

how can i disable the pick up from the groun?

[tender shard]

EntityPickupItemEvent

[agile hollow]

thx ❤️

[tender shard]

you need to set project.build.sourceEncoding to UTF-8

[wary harness]

can I do that in my main parent pom

[tender shard]

idk, I always set it in every pom to be sure

<properties>
  <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>```

[wary harness]

👍

[tender shard]

and then check if the file is actually saved as UTF8 in your IDE too

after that run mvn clean on the parent pom, then try again

ok thanks

using the commit button

[tender shard]

which git exectable is selected here?

[chrome beacon]

or the commit command

[chrome beacon]

Probably need to add the files you want

[tender shard]

i thought it said "git not installed"?

i said it in my last message, it ended up working after i launched intelij again

[steel swan]

how? do i drag and drop them?

I'd just remove the .git folder, then create a new git repo with with Git -> Create Git Repo (or however it's called) and then try again

[steel swan]

the.gitignore?

[tender shard]

but just for fun, you could try right-clicking the src folder and check if you see Git -> Add

[tender shard]

no

.git is a folder

probably IJ hides it

[steel swan]

yeah i dont see it

i see that button but when i click it nothing happenes

[tender shard]

if you now go the git tab again, do you now see some files you can commit?

[steel swan]

inside intelij idea?

[tender shard]

yes

here

[steel swan]

stil nothing

[tender shard]

open your project in file explorer and remove the .git directory, then run git init manually (or use Git -> Create repo in IJ)

[steel swan]

where is the .git file

[chrome beacon]

It's a folder in the root of your project

Windows will hide it by default, you need to enable hidden folders

[steel swan]

and how do i do that

[tender shard]

google

"<name of my operating system> show hidden files"

[steel swan]

Ok ill try that if other things dont work, but why cant i commit my files tho?

Boat doesn't have damage method

So I don't know

[quiet ice]

You might set the fire ticks, but that is beyond hacky

[kindred sentinel]

nice way

[quiet ice]

not sure if that would drop anything though. And might not be what you want visually

[kindred sentinel]

I think boat doesn't have animation of fire

it would just drop

even with 1 tick

[quiet ice]

Ah then it is a decent method

[full laurel]

Use VehicleDestroyEvent, check if the vehicle is a boat, if yes then create the item stack for the boat, & drop it naturally in the location where the boat was "broken"

[quiet ice]

I don't think that is what they want

[full laurel]

Ah, they want the items that drop when you actually break the boat? Like the sticks and stuff?
