maven is great

[coarse finch]

gradle 💪

[tender shard]

gradle is weird 😛

both are great tools

[coarse finch]

gradle is easier to me tho

maven uses xml 😨

[tender shard]

gradle is just way too complicated and sooo bloated although it has no features

I prefer maven

gradle cannot even shade stuff 🥲

[coarse finch]

wdym

[tender shard]

(unless you use a plugin made by some random github guy)

(also gradle thinks that it needs to run a daemon the whole time)

[coarse finch]

shadowJar {
    relocate 'dev.dejvokep.boostedyaml', 'me.kidneybean.generalutils.shaded.boostedyaml'
    relocate 'org.bstats', 'me.kidneybean.generalutils.shaded.bstats'
}```

boom

shading

[tender shard]

(and it needs to download itself first, and it's like 150mb from a slow server)

[tender shard]

haha no

[chrome beacon]

.

[tender shard]

you need a plugin for this to work

[coarse finch]

its like 1 line to add that plugin tho

[tender shard]

but again, I dont hate gradle. it's awesome. but maven is just better 😛

[tender shard]

yeah sure, if you like to depend on random people's plugins, go for it

maven however has an official shade plugin

[coarse finch]

i just tried to do a : after an if 🤣

my brain is pythonified

[tender shard]

IIRC gradle cannot even use your local maven repo without an explicit declaration

gradle is just overly verbose

people claim maven is verobse because of XML

but thats kinda bs

[coarse finch]

i gtg

[tender shard]

I mean which one is more readable?

compileOnly org.spigotmc:spigot:remapped-mojang:1.19.2-R0.2-SNAPSHOT

or a nicely formatted xml file

[tender shard]

aight, have a nice day ❤️

[quaint mantle]

I have a plugin Im getting help building, and I cant get it to drop the item. d:

[ancient plank]

Drop this item instead

[shy rock]

    static VillagerVault plugin;

    public villager (VillagerVault plugin) {
        this.plugin = plugin;
    }

    public static void init() {
    }

    public void createdvvilager(Location location) {
        Villager vvilager = location.getWorld().spawn(location, Villager.class);
        vvilager.setCustomName(ChatColor.GOLD + "Item Safe");    //Color and name of mob//
        vvilager.setCustomNameVisible(true);
    }
        @EventHandler

    public void onInteractEntity(PlayerInteractEntityEvent event) {


            if(event.getEntity().getType() == EntityType.SILVERFISH) {
        if (event.getRightClicked().getType() == EntityType.VILLAGER) {
            if (event.getEntity() instanceof Villager && event.getEntity().getCustomName().equals((ChatColor.GOLD + "Item Safe"))) {

            } }
        }
    }
}```
on eventhandler, theres an error on getEntity..
'Cannot resolve method 'getEntity' in 'PlayerInteractEntityEvent''
But its PlayerInteractEntityEvent ??

I've compiled my plugin using 3 different JRE's (18,17,16) and every time it's telling me the same error
has been compiled by a more recent version of the Java Runtime (class file version 62.0), this version of the Java Runtime only recognizes class file versions up to 61.0
I have no idea how it's still building in runtime 62

[dim bronze]

version 61 correlates to jdk 17, so compiling with 16 or 17 should work

[digital basin]

I'm using intellij, I've updated the pom, I've updated the maven run config, I've updated the project settings source language level and dependency, I've updated the project SDK settings and language level...

[dim bronze]

are you sure you have been using different jdks to compile?

[eternal oxide]

you need to set the source/target not the JDK you use

[dim bronze]

^

[digital basin]

I set that in the pom

[dim bronze]

how

[eternal oxide]

?paste pom

[undone axle]

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

[digital basin]

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

compiler source and target are set to 16

[eternal oxide]

InteliJ or Eclipse?

[digital basin]

InteliJ

[eternal oxide]

Artifacts or lifecycle to build?

[digital basin]

I'm using lifecycle

[eternal oxide]

package?

[digital basin]

yes

[eternal oxide]

add teh compile plugin to your pom as thats the only reason it would be broken

[digital basin]

The compile plugin?

[eternal oxide]

if everything is as you specified above

[strong parcel]

I didn't understand what you meant yesterday, but I think I do now. Because the Flood class is registered as both an event and a command, it opens one instance of Flood when the command is triggered and a new instance of flood every time the event is triggered, right?

[eternal oxide]

        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.8.1</version>
            </plugin>```

[digital basin]

Ahh, plugins is getting a red line under it when I use that

[eternal oxide]

it goes in the <build> section

[strong parcel]

How can I target an instance of a class to make sure they both use the same one?

[digital basin]

ah perfect, I'll reload maven and try building again

Just gotta restart my server to see if it works

[tender shard]

porn.xml

Whut?

[eternal oxide]

not sure that would be good porn

I remember it back in the day

[digital basin]

Jeeze, still reporting the same error,
io/github/klaustrix/greentext/GreenText has been compiled by a more recent version of the Java Runtime (class file version 62.0), this version of the Java Runtime only recognizes class file versions up to 61.0

[dim bronze]

#help-development message

[tender shard]

update your java

[tender shard]

you are trying to compile/whatever something that uses a newer java version than you do. where does this message come from? maven?

[digital basin]

From the minecraft server on load up

[dim bronze]

#help-development message @tender shard is their pom which looks correct

[eternal oxide]

You can;t be correctly updatign yrou jar on the server

[tender shard]

then you're in the wrong channel. go to #help-server. and update xour java

[eternal oxide]

My guess is you have the server running and fail to update

[dim bronze]

make sure you haven't got multiple jars in your server for the same plugin

[eternal oxide]

PC crashed so catching up

[digital basin]

Update the server java?

[eternal oxide]

no your plugin

you copy it from yoru target folder to your server?

[digital basin]

I started on Java 18, I stop the server, delete the old file, upload the new one, start the server again

[tender shard]

are you using maven @digital basin ?

[digital basin]

yes

[tender shard]

https://blog.jeff-media.com/common-maven-questions/

[eternal oxide]

he is, lifecyles package to build

[tender shard]

read this pls

[eternal oxide]

Your pom is now fine. you are either failing to build or not uploading the correct jar

[dim bronze]

when in doubt invalidate caches and restart

[tender shard]

yeah that's usually a good hint but not if the problem is the java version

[digital basin]

https://imgur.com/a/rkuJGLk
This is everything I've updated

[tender shard]

SO MUCH TO DO, SO MUCH TO SEE

[tender shard]

?paste your pom.xml file

[undone axle]

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

[dim bronze]

they have

scroll up questions hae been asked and answered

[tender shard]

are you using intellij?

[digital basin]

yes

[tender shard]

File -> Project Settings -> set the java version to 17 or above

[digital basin]

https://paste.md-5.net/ivevoyenin.xml
here's an update

Already did that

[tender shard]

set java to 17 instead of 16

[dim bronze]

do you have maven installed on your computer separate to intellij? you could try build using mvn package to see if intellij is messing anything up

java 17 is fine, it's what the server is running on

[eternal oxide]

Confirm, you are using the menu on the right, Maven and package in the lifecycle section? Not building via artifacts

[digital basin]

I tried 18, 17, and 16 but I can bump everything back up to 17

https://i.imgur.com/T1lmVfk.png
The highlighted option

[eternal oxide]

k

[digital basin]

Maven is part of intellij I think

[tender shard]

okay lets start from scratch. send the FULL maven log pls

[digital basin]

Where do I get that

[tender shard]

not just the error message. please ?paste the WHOLE maven log

ok wait

i'll explain, lemme start IJ

[dim bronze]

the error message he sent isn't from maven

its from the server

[digital basin]

the error is coming from the minecraft server, not maven

[eternal oxide]

we need the maven log to see if its even building

everythign you changed shoudl have altered the target version and its not

[tender shard]

oh

[eternal oxide]

So we are guessing there is a build error

[dim bronze]

when it builds, the bottom pane should show a maven window with the build logs in

[tender shard]

then your server is running java 16 or older

[dim bronze]

its running 17, bytecode v61 is jdk17

[tender shard]

huh

that is weiiiird

[digital basin]

https://paste.md-5.net/ayidajevor.cs
This is the build output?

[tender shard]

then I also cannot help

[digital basin]

I'm running Spigot 1.19

[tender shard]

I am like 1000% sure that your server runs java 16 or older

[digital basin]

on an apex host

Is there a way to verify the java version?

Maybe a console command?

[tender shard]

yeah, looks good

[tender shard]

sure

java -version

[dim bronze]

confirm there is only 1 GreenText.jar plugin in your plugins folder

versioning sometimes messes that up

you move the file over and it doesn't overwrite the old one because they are different versions

[tender shard]

(usually spigot uses the latest file if 2 .jars have the same "plugin" name)

but yeah cant hurt to double check this

[dim bronze]

not in my experience

[digital basin]

Each time I delete the old file, a new one generates, I delete the one on the server and upload the new one, even changing the version number to make sure it's different each time

There's only ever one file in existence at a time

[tender shard]

do java -version or paste your whole latest.log

?paste

[undone axle]

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

[tender shard]

just paste your whole latest.log there ^

[digital basin]

java -version produces a unknown command error

I'll post the log

[tender shard]

oki

[river oracle]

you need to set a java home environment variable if thats the case

[dusk flicker]

?javahome

[tender shard]

fuck that, just let them paste the log

[dusk flicker]

we need a command for it tbh

[dim bronze]

dont think thats the problem, intellij finds the jdk fine

[tender shard]

I am like 99.9% sure that they run java 16 instead of 17

[dim bronze]

its path is manually specified in intellij

[tender shard]

intelliJ has nothing(!) to do with your server

[river oracle]

just because intellij found the jdk doesn't mean your computer has

[dim bronze]

the server is running externally

on apex

[tender shard]

just paste your latest.log pls

[digital basin]

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

here you go it's a biggen

[tender shard]

thats not the full log

restart your server, then open latest.log again and paste the full file pls

[digital basin]

Okay one sec

[tender shard]

the log gets rotated automatically at 0 or 1 in the night

so yeah pls restart it and send it again

[iron glade]

Do you guys know that feeling when you're facing a problem while programming and eventually you come up with a 3 line solution xd

[tender shard]

yep

[iron glade]

It's so relieving

[tender shard]

mostly the 3 line solution involves NMS though lol

[iron glade]

:(

[digital basin]

I just have to dc my players to restart so I gotta explain whats up

[dim bronze]

the server isn't the problem here

[tender shard]

take your time. but we can't help you until you posted it

[dim bronze]

its intellij/maven not compiling with the right target

[tender shard]

huh

[digital basin]

I thought that was the problem

[tender shard]

I thought it compiles fine

[dim bronze]

class file version 62 is java 18

yes it compiles fine

just not with the correct target

[tender shard]

does your plugin compile fine, or does it not?!

[dim bronze]

that's whats important

no error doesn't mean correct

[digital basin]

It compiles but the compile version is always too high even when set lower

[tender shard]

does maven say "BUILD SUCCESS" or does it say "BUILD FAILURE" when you compile?

[dim bronze]

success you've read the output

that doesn't matter

[tender shard]

ok ok good

[tender shard]

it DOES matter?

if it says "build success" then its obvious that the only problem is the server running java 16 🙂

[wet breach]

show your pom

[dim bronze]

the fact its successfully built doesnt matter if the target is still incorrect

the srever

[digital basin]

The problem is that the server only wants java 17 or lower, but the plugin is always being built in version 18 for some reason even when I set the settings lower

[dim bronze]

is not

[tender shard]

it compiles fine

[dim bronze]

running 16

[tender shard]

their only problem is the server runing java 16 instead of 17

[eternal oxide]

can you try this...double click on Package, not using any of yoru other bits.

[dim bronze]

the problem is that maven isn't targetting java 17

[wet breach]

compiling isn't their issue, their issue is compiling for the wrong java version

[tender shard]

no

[tender shard]

no

oh wait

kinda true

[wet breach]

in order to fix that, I need to see their pom

[dim bronze]

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

think the version has been bumped since

that's the only difference

[tender shard]

they compiled a plugin for java 17 but their server runs java 16. that's the problem. so either update the server's java or downgrade the compiler target in your pom

[digital basin]

https://paste.md-5.net/ivevoyenin.xml
This is the latest pom

[dim bronze]

they haven't compiled for java 17

[tender shard]

^

[dim bronze]

they've compiled for 18

thats the problem

[tender shard]

oh yeah

[digital basin]

Yeah it's compiling through java 18 despite changing all the settings

[tender shard]

youre right

[eternal oxide]

The problem is teh pom says its compiling for 16 but its not

which means he can;t be using the pom

[dim bronze]

personally, i would download maven separately

and run it in the command line

remove intelij from the equation

[eternal oxide]

he has to be building using artifacts

[dim bronze]

or intellij is using some other weird option in its maven settings

[eternal oxide]

possible

[dim bronze]

ctrl ctrl and type mvn package

[worldly ice]

seems like you're missing something in your compiler plugin

should have a config section like that

[river oracle]

not necessarily required :s

[wet breach]

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

fixed it

[eternal oxide]

doesn;t need it, its in the pom properties

[worldly ice]

ah, mb

[wet breach]

pom properties isn't used anymore

[river oracle]

really O.o

oh boi

[wet breach]

at least not for targeting java versions

[eternal oxide]

? it is in Eclipse

[dim bronze]

used to work in intellij with me?

[wet breach]

eclipse does its own thing

[tender shard]

yo guys it's not christmas today, so enjoy my latest christmas song https://soundcloud.com/le-crochet/kunsumgellschaft-ich-konsumier-auch-wahrend-der-heiligen-zeit

[dim bronze]

but this is why i haven't used maven in a long time

[wet breach]

Well I fixed it for you, should work now for the version you are wanting

[dim bronze]

multiple places to define everything

[digital basin]

I'll try these pom changes

[dim bronze]

btw Klaustrix is the one with the issue, not me

[wet breach]

ah

[digital basin]

👋

[wet breach]

well either way

[digital basin]

Uploading and testing now

[dim bronze]

so

<properties>
    <maven.compiler.release>17</maven.compiler.release>
</properties>

standalone doesn't work anymore?

[outer river]

hello, why i have this signs pls ?

[wet breach]

maven stopped using the properties for java version targeting because it was getting too confusing when the compiler plugin already accepts a tag for it

eclipse has its own compiler and they do their own thing

[river oracle]

something with your ide seriously can't expect anyone to help you with so little info given

[eternal oxide]

when did maven drop that?

[dim bronze]

when did this happen?

[eternal oxide]

do you know the version?

[outer river]

is that just because i have an error in my code ?

[river oracle]

I don't fucking know

you have provided 0 info on your IDE or anything

how am I supposed to help you

[wet breach]

around java 11 I think @eternal oxide

[dim bronze]

shouldn't matter what java version

[outer river]

i mean, i was expecting for a misclick combination of keyboard

[eternal oxide]

I guess I never noticed as I use Eclipse

[river oracle]

dude I ain't got a clue what your going on about are you messing with me or something

[desert frigate]

how would i remove just 1 item from a players inventory?

[wet breach]

for the most part, eclipse compiler works the same as the maven one, but they have some minor differences here and there lol

[desert frigate]

instead of the whole stack

[river oracle]

get hte item set the amount to the amount -1

[dusk flicker]

set an amount to the itemstack iirc

[digital basin]

Wow still getting the error I'm just genuinely cursed

[dim bronze]

looks like you have whitespace characters turned on

which ide?

[dusk flicker]

looks like eclipse

[dim bronze]

okay, i would suggest installing maven separately

[wet breach]

you shouldn't o.O try doing a clean build

[dim bronze]

https://maven.apache.org/download.cgi

[outer river]

yup, eclipse

[dim bronze]

Window >> Preferences >> General >> Editors >> Text Editors:
[x] Show whitespace characters

[wet breach]

the only other thing I can think of is that you are making IntelliJ build it and not maven

[dim bronze]

staight from stack overflow

[digital basin]

I can try downloading and installing maven, while I try that, how do I clean build?

[dim bronze]

my thoughts

[drowsy helm]

Mvn clean

[dim bronze]

double tap ctrl and type mvn clean package

[desert frigate]

i have a item stack but how would i set it?

setting it needs the index

[river oracle]

ItemStack#setAmount

[dapper pond]

my server is paper 1.19.2, and i keep getting that chat message validation failure so i decided to try and go back to a later version like 1.19. Except now it makes my server crash because its trying to load chunks from 1.19.2, is there anyway to go back a version and not have it crash like this?

[river oracle]

loop

[drowsy helm]

You dont need to package if you’re just cleaning

[river oracle]

they are pretty fucking awesome

[dapper pond]

should that be in help server

[wet breach]

while that is true, they still need to compile

[dim bronze]

but they'll need to package afterwards

[drowsy helm]

Ah

[drowsy helm]

Yes

[dapper pond]

ok mv

[quaint mantle]

I want a solution

[dim bronze]

😄

[river oracle]

bedrock

use java

[outer river]

@dim bronze in wich section ?

[quaint mantle]

Gyser

[dim bronze]

the response was quite old so might have changed

[drowsy helm]

We have 0 context from this video

[river oracle]

;/ have you tried fixing your problem yet

[dim bronze]

can you search the settings for the term 'whitespace characters'

[desert frigate]

thanks

[river oracle]

np 👍

[quaint mantle]

yes

I use GeyserMC In Java server but It does not work

[river oracle]

well not sure what to do then

so what you must had been doing was using IntelliJ's ant build instead of maven

[dim bronze]

no way was a clean package the solution 😑

thats annoying

[digital basin]

Frostalf's pom + clean package

[shy rock]

could anyone help me with some playerInteractionEntityEvents ?

[outer river]

@dim bronze thx, i foud it

[river oracle]

just ask

[quaint mantle]

I want a solution

[sharp heart]

do someone know how to calculate the angle (-180 to 180) between player direction and a location ?

[digital basin]

Well I super appreciate all the help guys

[quaint mantle]

🥲

[river oracle]

you never even stated your problem buddy

[digital basin]

Thanks for sticking with me ❤️

[river oracle]

you just sent a video

[dim bronze]

i mean it makes sense. no code changes so maven doesn't recompile

so class version never changes

should have seen that coming

[river oracle]

?paste

[sharp heart]

do someone know how to calculate the angle (-180 to 180) between player direction and a location ?

oh

[shy rock]

errors on all events at bottom

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

[river oracle]

can I get the stack trace

[worldly ice]

you have a syntax error

[sharp heart]

👉 do someone know how to calculate the angle (-180 to 180) between player direction and a location ? 👈

[worldly ice]

remove getClickedEntity after event

[shy rock]

still wont work

[worldly ice]

what's your new code

[river oracle]

bruh don't know how to fix a syntax error 💀 please see what your IDE is telling you and fix it its very descriptive

[dim bronze]

take the location as vector, subtract the players location as a vector

and get the direction of the vector

[quaint mantle]

my problem is in plugin znpcs

When I write command

/znpcs create

And write the requirements, the red letter appears to me, and it does not spawn the npc

[shy rock]

What it tells me doesnt fix it

[river oracle]

is it your plugin?

[drowsy helm]

organise your code dude

[quaint mantle]

Nooo

[river oracle]

bruh this aint the right channel

plus go bug gyser / plugin creator

[sharp heart]

yes but with this method it's always positive

I need to know if the location is at the left or the right of the player

so -90 or 90 in example

[quaint mantle]

The problem is not with them, I have already asked them

[river oracle]

then ask the plugin creator

if its not an issue with them ask geyser

if geyser says not our problem than figure it out yourself someone is lying spigot isn't the issue here

[quaint mantle]

I don't have the server discrod

[river oracle]

then find it

[quaint mantle]

How 🤔

[wet breach]

generally located on most plugin resources these days

for the authors discord

[river oracle]

don't ask me I don't own the plugin If its not on their plugin page dm them on spigot

[wet breach]

or how to get a hold of them

[quaint mantle]

😂

Ok sorry

[iron glade]

Anyone knows if there is a plugin that makes inventories "stackable", e.g. you open a chest, and there is a chest inside, if you idk, right click? that chest it opens that chest's inventory, etc

[quaint mantle]

I'm go here #help-server

[drowsy helm]

so a chest in a chest?

[river oracle]

I mean equally speaking no one in help server will also beable to help you

[drowsy helm]

that would cause so many issues

[wet breach]

oh you mean like shulkers

[iron glade]

yeah something like that

[dim bronze]

just checked the javadocs, you can probably just use the angle method which gives it in radians. If > pi rads then to the left?

[drowsy helm]

shulkers dont stakc inside of eachother

[river oracle]

he could just prevent the items from being nested

[iron glade]

Do you guys think it would be even possible to do smth like that?

[river oracle]

yea probably very easily

[drowsy helm]

yes, with nbt easily

[iron glade]

and when you close that inventory, the previous inventory opens (if there was any)

idk, was just something that came to my mind :d

[drowsy helm]

are you talking about a physical chest

or just a gui

[river oracle]

just a gui I'm assuming

[drowsy helm]

because if its a physical chest you're asking for a bookban chunk

[river oracle]

didn't mojang fix book banning

[wet breach]

https://www.spigotmc.org/threads/vaults.30815/

[drowsy helm]

did they?

[river oracle]

iirc they now allow chunks to store more than 1mb of data

[iron glade]

Well, let's say you have a chest with items inside, you destroy that chest and have it in your inventory, if you place that chest into another chest now and right click on the chest that you just put inside another chest it opens a gui with the stuff stored in that chest

[drowsy helm]

ah

what does it do, throw an error?

or just cut off data

[river oracle]

a half assed fix but a fix none the less

I'm not sure tbh

[wet breach]

this is surely to cause a lot of problems and potential duping

better to use something like vaults

[sharp heart]

What do u mean, I don't understand

[wet breach]

where there isn't a physical chest required

[iron glade]

hm true

[drowsy helm]

just sounds like a vault with extra steps

[stuck flax]

is there a way to get the player's client brand using the Spigot API? If not, how else could I do it?

[dim bronze]

depends on if the client mimics the notchian client or if it sends its own information like i assume lunar and badlion does

what this information is, however, i have no idea

i don't think its intended to be public knowledge because it can be faked but its probably been reverse engineered

[river oracle]

Client signatures can indeed be faked very easily

[stuck flax]

Many plugins like an anticheat I know will show you the client brand, I wanna know how to get that

[river oracle]

if your using it to prevent hackers don't bother

[stuck flax]

I know it can be faked, I just want to be able to get it

[dim bronze]

which is why intended to be public

[dusk flicker]

I dont think you can easily with the spigot api

[dim bronze]

it probably is

[dusk flicker]

but Paper has a method for it

[river oracle]

no point of this in an anti cheat clients won't identify themselves and someone on forge isn't that much more likely to be hacking than on a client not identifying itself as forge

[dim bronze]

but you just have to find it online

[dusk flicker]

I would recommend you dig into their implementation and see how they did it

[dim bronze]

really? hmm

[dusk flicker]

https://jd.papermc.io/paper/1.19/org/bukkit/entity/Player.html#getClientBrandName()

[dim bronze]

i don't think most alter this?

[stuck flax]

I saw on a thread that it's possible to do it with ProtocolLib, is this true?

[dim bronze]

iirc its sent in the handshake packet

i didn't realise you meant this information

so yes, possible with protocol lib

[stuck flax]

👍 thanks

[dim bronze]

i may be incorrect on this

can't see it mentioned in https://wiki.vg/Protocol

[dusk flicker]

it might be through messaging channels now that im thinking of it

Check this out https://github.com/PaperMC/Paper/blob/master/patches/server/0474-Brand-support.patch

[dim bronze]

hard to read the patch without surrounding code

[dim bronze]

not something i can confidently speak about without testing

seems like a common enough question, had any luck with google?

[sharp heart]

bro I just searched like while 3hours

nobody have a solution

something that work

[dim bronze]

what do you need this angle for

I remember trying to do this before I actually got taught vectors and resolving in school so if that's not something you're comfortable with then maybe read up but this looks helpful https://www.spigotmc.org/threads/calculate-angle-between-two-players.282430/

    public void onPlayerWearsItem(PlayerInteractEvent event)
    {
        Player player = event.getPlayer();
        player.sendMessage("Checking for helmet on player " + player.getDisplayName());
        if(player.getInventory().getHelmet().getItemMeta().getLore().get(0) == "§2These goggles grant you the")
        {
            player.addPotionEffect(new PotionEffect(PotionEffectType.NIGHT_VISION, 300, 1, false, false));
            Bukkit.broadcastMessage("PotionEffects!");
        }
    }```
I'm trying to make it so when you wear a specific helmet (custom ItemStack) you get night vision, but this code doesn't work. Any suggestions?

right now im checking if the lore on the helmet being worn matches the custom helmet i made

and i tried checking to see if ItemMetas matched and if they were the same ItemStack

but its not working

[dusk flicker]

?notworking

[undone axle]

"Does not working" is a useless statement. Please describe what exactly is not working, what you expect it to do, and what actually happens. If you get any console errors, also ?paste the entire stacktrace.

[sharp heart]

ok ty

[worldly ingot]

Don't compare strings with ==. Use .equals()

Surely we have a command for that, no?

[dusk flicker]

?comparestrings

not that im aware of

You should make one Choco :p

[night torrent]

ok well thats not the problem because i tried by checking if itemmetas matched

[eternal oxide]

?strings

[night torrent]

        {
            player.addPotionEffect(new PotionEffect(PotionEffectType.NIGHT_VISION, 300, 1, false, false));
            Bukkit.broadcastMessage("PotionEffects!");
        }```

ItemManager is a seprate class and Goggles is the static ItemStack

[dusk flicker]

You would probably not want to compare itemmeta

Rather use something like PDC

[night torrent]

?

[eternal oxide]

why not just ItemManager.Goggles.isSimilar(player.getInventory().getHelmet())

[topaz patio]

hi

[eternal oxide]

it will compare meta too

[dusk flicker]

Doesn't isSimilar only check the amount tho

[eternal oxide]

everything except amount

[dusk flicker]

ye

im just concerned if this helmet can take dura/have diff enchantments

[night torrent]

I'll give that a shot! I'm somewhat new to java, I mainly do C#

@dim bronze hi can you do a voicechat real quick? i'm in hokib's team and we've been trying to figure this out for 3-4 hours

[night torrent]

do you study the cmds

[dusk flicker]

ive been in here for a long ass time

at some point they just come naturally

I have 32k+ messages lol

[topaz patio]

@worldly ingot can i get some helps please its very urgent

[dusk flicker]

?ask

[undone axle]

If you have a question, please just ask it. Don't look for staff or topic experts. Don't ask to ask or ask if people are awake or available. Just ask the question to the channel straight out, and wait patiently for a reply. Make sure you use the right channel regarding the topic of your question. Create a thread in case the channel is already in use!

[dusk flicker]

you havent even asked a question

[night torrent]

It worked! Thanks a lot

also, is their anyway to tint the screen a color?

[drowsy helm]

finally figured it out

[spiral birch]

Hey guys, i'm trying to show to players an arrow in their actionbar pointing them to a block location, according to the direction their looking at
i'm struggling a lot with vectors and I would like to know if someone could help me doing this
by the way, as I need to convert angle to arrows, a basic angle will not be enough since I need to tell to the players which way they need to turn

[drowsy helm]

use the generic look at method

                loc.setDirection(entity.getLocation().subtract(loc).toVector());```

and get the pitch which you convert into an arrow

[glossy scroll]

what

that is

not true

First: get the displacement vector

blockDir = blockLoc - playerLoc

then get the facing director

playerLoc.getDirection

[spiral birch]

yeah but then how can i get the angle ?

[glossy scroll]

Vector.angle

[spiral birch]

since I need to know like if the player needs to turn to the left or the right i would need something negative or positive

[glossy scroll]

yes exactly

[spiral birch]

and vector.angle is always positive

[glossy scroll]

you can use blockDir.dot(playerDir)

that will give you a vector that is positive (to the right) or negative (to the left)

[spiral birch]

can I use > / < on a vector tho ?

[glossy scroll]

huh?

[spiral birch]

how can i check if the vector is positive or not

[glossy scroll]

oh

the y value

of the dot product

will be positive/negative

or you could just use a compass

i should also mention

[outer river]

hello, what should i put here to target a method pls ?

[glossy scroll]

the y values of these vectors need to be set to 0

[glossy scroll]

what are you trying to do?

@spiral birch see above btw

[worldly ingot]

This depends heavily on whether or not you're using reflection, or if you just want to invoke some method with a given signature

[outer river]

trying to get a list of command from a category of my config and link him to my categor'ys name

[drowsy helm]

use a functional interface

[glossy scroll]

not even

just use the list as the value of the hashmap

and then do Dispatcher(map.get(key)) or whatever

and also lowercase Dispatcher

[outer river]

i'll try

thx

[sinful rapids]

  loc.getBlock().setTypeId(31:2);

I can't put this id, can I how to solve?

[outer river]

setTypeIdAndData

[silent wave]

hi i have issues with a plugin
i had a tab list plugin and when i delete this plugin the tab list dont disappear
what can i do to fix it?

[slate mortar]

wdym

[sinful rapids]

loc.getBlock().setTypeIdAndData(31, 2);

So it doesn't work the same, what did I do wrong?

[outer river]

loc.getBlock().setTypeIdAndData(31, 2, false);

[coarse finch]

what would be the best way to save boolean data about the player

[dry forum]

how can i create a fallingblock using nms? using new FallingBlock it asks for a properties object, what is that and how do i make it

[eternal night]

Why

Nms should be the last answer

[dry forum]

because only 1 person see it

[gaunt relic]

You should use World spawnFallingBlock

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/World.html#spawnFallingBlock(org.bukkit.Location,org.bukkit.block.data.BlockData)

[eternal night]

That spawns them for everyone tho

[dry forum]

that isnt nms

[gaunt relic]

oh, you want just one person to see it?

[dry forum]

also am i missing smthn why does Material. in NMS only have like 15 materials

yhes

[gaunt relic]

you need to send the spawn packet to just that person

[eternal night]

Well, generally falling block entity is what you wanna base your stuff on

[dry forum]

this is the issue

[gaunt relic]

i would look up how this method works and send it to just that player

[dry forum]

umm it doesnt work like that

im using nms

[gaunt relic]

yea, what I mean is you should look in the source code how it is done

and instead of sending to everyone in the world, just send to the player you want to see

[dry forum]

theres hundreds of files in the source code idk what 1 its in

[gaunt relic]

look in CraftWorld class

[quaint mantle]

Just a yes or no, should I run database "preparedStatements" async?

[eternal night]

Yes

[drowsy helm]

yes

most database stuff should be done async

[eternal night]

Technically not too needed

[gaunt relic]

looks like it is done in EntityFallingBlock#fall

[eternal night]

But like

Shove all dB interactions onto their own tbrssd

[dry forum]

alright thanks ill look at it

[eternal night]

Thread

[quaint mantle]

I see then, thanks! =)

[dry forum]

is this 1.19.2 do you know?

[gaunt relic]

yea i looked up on latest source code of spigot

?stash

[undone axle]

https://hub.spigotmc.org/stash/

[gaunt relic]

that is a nms class, you gonna have to decompile it

[dry forum]

that didnt work on 1.19.2 BlockPosition doesnt exist but i fixed that but the method is completely different and i dont rly understand it FallingBlockEntity entity = FallingBlockEntity.fall(s, new BlockPositionSource(loc.getX(), loc.getY(), loc.getZ()), CraftMagicNumbers.getBlock(material).defaultBlockState(), CreatureSpawnEvent.SpawnReason.CUSTOM); the loc.getX() y and z and all of that says its unrecognized

[river oracle]

is there any way to put a player in a sort of spectator state in survival. The main issue I'm theorizing is the restriction of hitting another player if the player in "spectator" is in the way. There are a couple ways I could think of doing this, but I'm not positive

1. Player#hidePlayer(Plugin plugin, Player, Player) hide the player for all online players
2. Player#setInvisible() my note on this one is the possibility they can still be interacted with.
3. Packets (I would like to not do this), but I know its possible

Now this is one of those things I wish i could try and see, but I don't have enough resources to run 3 minecraft clients and a server on my pc

[gaunt relic]

that is FallingBlockEntity not EntityFallingBlock, plus that method sends to everyone on the world, you should look in it to see how the packet is sent and the fallingblock object is constructed, so you can send it to just one person

[dry forum]

EntityFallingBlock doesnt exist

[gaunt relic]

that class is in net.minecraft.world.entity.item.EntityFallingBlock

[dry forum]

huh?

[gaunt relic]

you gonna have to decompile the nms and look on it

[hushed pawn]

You need to store player state and cancel specified events for specified players

[river oracle]

yep fully aware of this I am more affraid of them being a blocker for players in hte game e.g. you can stand infront of a block to prevent another player from breaking it as a spectator

or cause collision to a player running across a bridge and throwing them off into the void

hmmm I actually should beable to pull off tests with another mob and 2 clients I should be fine catually for trying and seeing this

[hushed pawn]

Then i guess you have to hide player with protocol lib, not sure how tho

[coarse finch]

i have a few questions about persistent data storage.

• does it save when the server reboots?
• can i store data on offline players?
• are there better methods?

[drowsy helm]

wdym by "better" methods

but yes it does save over reboots

[worldly ingot]

NMS' Material isn't the same as Bukkit's Material enum. Blocks and Items are the two corresponding classes

[drowsy helm]

and no, i dont think you can set pdc on offline players. I may be wrong

[glossy scroll]

to confirm, is tehre something like EntityShootBowEvent but for all projectile items?

[novel kite]

Is there any way to find if there are any data packs installed?

[drowsy helm]

i mean theres ProjectileLaunchEvent but thats as far as it goes iirc

can make your own custom event out of it

[river oracle]

just a note don't use persistent data to replace a database

Use it to store small bits of data on things like items players etc

[coarse finch]

im using it to store mute data

[vocal cloud]

Well if you want to be able to mute offline players you will absolutely want to use a db

[coarse finch]

eh it doesnt matter much

also can someone reset my nickname, its set to my old username

hos something in java changed where if you do like if (null) it throws an error?

because im getting all sorts of errors i didnt used to get

[outer river]

You're never progressing your iterator.
Add list.iterator().next() to the end of your while loop

[lost matrix]

Well its clearly a permission problem. Properly remove the permission requirement from your plugin.yml and make sure to compile and copy the jar afterwards

[quaint mantle]

yes but I want there to be a permission?

like if the player doesn't have x permission then u cant do x command so you get the "You don't have permission for this command!"

[lost matrix]

Then whats the problem?

[quaint mantle]

it doesnt work

it doesn't give me the no permission message

Hey what's a good example of getting the horn type from a item stack is?

does actionbar not send in adventure mode?

[frank compass]

does anyone know how to code flying boots basicly when you put on boots that are named "Flying boots" you are able to fly like in creative mode can anyone help?

[lost matrix]

Sure. There are several approaches. I would listen for when the player equips the boots and give him fly.
When he unequips the boots then you revoke it. Thats the simplest one if you know how to listen for armor equips.

[sturdy frigate]

Easy way to setup a navigator through diff worlds with a compass?

[lost matrix]

What exactly does a "navigator" do?

[sturdy frigate]

Teleport across different worlds like a lobby and whatnot

[lost matrix]

And whats the point of the compass?

[sturdy frigate]

No point, just as an item that'd be immediately noticible

Since a lot of servers use that

You know how you can right click on it and it displays a GUI that you can select different worlds from

[lost matrix]

Well then you give the compass some pdc data, prevent people from dropping it,
listen for the interact event and open a GUI that lets you click on different worlds...

[sturdy frigate]

Okay will check those out thanks

[drowsy helm]

anyone know what the clientbound message packet is called for protocol lib

Hey guys is there a good API/Lib for scoreboards?

[boreal sparrow]

Hey, my friend has this minigame that has three maps in three seperate world. Is there a better way than constantly going:
switch(args[0]){
case "World1":
//teleport to world 1
break;

case "World2" etc.
}

I could have a seperate command for each map/world, but is there a streamlined way of doing this?

[lost matrix]

Yes.

World world = Bukkit.getWorld(args[0]);
if(world != null) {
  player.teleport(world.getSpawnLocation());
}

[boreal sparrow]

this is brilliant

[buoyant viper]

idk probably both CHAT and SYSTEM_CHAT

system chat? cant see that anywhere

i think chat is supposed to work, just doesnt look like it does on latest version of protoocl lib

whats the best way to separate different worlds/maps for a minigame?

Separate in which context?

[frosty tinsel]

Hi, I wanted to ask. You know how many people use Pterodactyl, to run their networks, which uses Docker to run each minecraft server in a docker container. Isn't it kinda ineffective, when there are running multiple JVM instances along each other? (when there are 2+ servers on one machine)

[boreal sparrow]

for example: lets say I have an enum that has game states like IN_GAME, WON etc.
I really dont want to go IN_GAME_MAP_1, WON_MAP_1, IN_GAME_MAP_2...
So is there a way to handle every world on it's own?

[frosty tinsel]

have a Game class, which handles it

and a GameManager

for example

[lost matrix]

You will have to run a different jvm instance for every server anyways. And yes you are sacrificing about 10% of your CPU and memory
when using Pterodactyl. But you also get the benefit of modularity.

[drowsy helm]

how is it ineffective?

[frosty tinsel]

aha, I didn't know there's a JVM instance for each process

that makes sense now

[rough basin]

What should I do to remove off hand and else?
I just want only Main hand

[drowsy helm]

the jvms for two servers are separate anyway, yeah theres the headroom for the container but its really not much

[lost matrix]

Sure. There are a lot of ways. Just do some object oriented programming with what Tomasan suggested

[lost matrix]

Set the EquipmentSlot for the AttributeModifier

[boreal sparrow]

ok ty

[frosty tinsel]

The worst thing in making minigames is handling Events

with Bukkits imo bad event API

[lost matrix]

Whats so bad about that? Sounds quite simple to me...

[frosty tinsel]

it breaks oop

you don't really have much control over it

[lost matrix]

It does not break any oop concept. And you have full control over it.
What more control do you need?

[glass mauve]

hey :D
I used ProtocolLib to spawn Item Frames (entities) for a specific player
and I stored the entityID, how can I remove these Item Frames later with the entitiyID

[lost matrix]

By sending a destroy packet

[rough basin]

can you show me example?
I can see getSlot only, where is setSlot on AttrubuteModifier?

[lost matrix]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/attribute/AttributeModifier.html#<init>(java.util.UUID,java.lang.String,double,org.bukkit.attribute.AttributeModifier.Operation,org.bukkit.inventory.EquipmentSlot)

[rough basin]

oh bruh why i'm seeing methods

Sorry

[glass mauve]

where can I fiind it in wiki.vg/Protocol? or do I just use spawn entity packet and configure some stuff to destroy it?

anyone else available to pull the 5.0.0 snapshot?

https://repo.dmulloy2.net/#browse/browse:public:com%2Fcomphenix%2Fprotocol%2FProtocolLib%2F5.0.0-SNAPSHOT%2F5.0.0-20220727.143709-4

idk if im typing it wrong

[lost matrix]

For me it worked yesterday

[drowsy helm]

        <dependency>
            <groupId>com.comphenix.protocol</groupId>
            <artifactId>ProtocolLib</artifactId>

            <scope>provided</scope>
        </dependency>```
does this look correct?

i tried with every combination of version and public/releases/snapshots on repo

[glass mauve]

btw someone know when protocolLib comes to 1.19?

[drowsy helm]

snapshots are out

thats whawt im talking about rn

[glass mauve]

oh lol xDDDD

didn't saw it

but how can I download it for my server?

[lost matrix]

Doesnt break any oop concept but the constant rebaking of the handler list is a garbage approach. Thats for sure.

[lost matrix]

Any reason why you need this super specific snapshot version??

[drowsy helm]

i tried with 5.0.0-SNAPSHOT aswell

[lost matrix]

Just use 5.0.0-SNAPSHOT

[drowsy helm]

was just throwing stuff at it to see if it works

[lost matrix]

Ah i see

[drowsy helm]

omg

smile

im dumb

i was in offline mode

[lost matrix]

[rough basin]

How much is player's default movement speed

nasusQMeta.addAttributeModifier(Attribute.GENERIC_MOVEMENT_SPEED,new AttributeModifier(UUID.randomUUID(), "MovementSpeed", -0.5, AttributeModifier.Operation.ADD_NUMBER, EquipmentSlot.HAND));

-0.5 just stops player

[glass mauve]

where can I download that for my server as jar

[river oracle]

.2 by default

[rough basin]

thanks :)

[drowsy helm]

in maven

just change the version

[glass mauve]

yea but I also need it in my plugin folder

[drowsy helm]

hold up i gotchu

https://ci.dmulloy2.net/job/ProtocolLib/lastSuccessfulBuild/

[glass mauve]

ty

[rough basin]

still not working, i changed -0.5 to -0.1 but still stops

[glass mauve]

hm with 5.0.0 I get problems using WrapperPlayServerSpawnEntity
cause it imports com.comphenix.protocol.reflect.IntEnum;
what is the equivalent?

[glass mauve]

just removed that part dont need it

You can't move. A negative speed xD

That's a new one

Im trying to add 1 persistentData named Q-Stacks,
but this commands always return 1 and Q-stacks is still 0, what is wrong?

[crude charm]

Is 1.19 spigot working and stable to large scale development? Or would it be worth using something like purpur for newer versions as I have in the past?

[lost matrix]

purpur builds on paper and paper builds on spigot.
So if spigot isnt ready then purpur isnt as well.

[drowsy helm]

anyone ever tried converting a string with chat color to grayscale

[crude charm]

I'm aware of that but they make slight changes, is spigot 1.19 released? As far as I'm aware it is

[lost matrix]

spigot 1.19.2 is stable and released

[crude charm]

Tbh idek when 1.19 or even 18 released, don't usually use / work on newer version, but for this project it makes sense to

[crude charm]

Aight thanks

[glass mauve]

OOF the plib wrapper dont work for 1.19

[crude charm]

Last update I followed was 1.10, know nothing about everything after that

[lost matrix]

They do. Just look at the nms packet. I think its an IntList instead of an int[] now

[glass mauve]

I get this
FieldAccessException

[lost matrix]

Oh you mean the wrapper classes... yeah they are outdated for years now

[glass mauve]

yea

so I need to do everything manually?

[glass mauve]

how? only worked with wrappers before

[hushed pawn]

How to check if some players from List are close enough to some locations? (every tick)

[lost matrix]

Go to wiki.vg and look at the fields

[hushed pawn]

What is the best way?

[crude charm]

Do newer versions of spigot have a way to set the defense value of armour without giving it protection 1000000?

[rough basin]

How to add values in persistentData?

[glass mauve]

yea and then? I have:

PacketContainer packet = PROTOCOL_MANAGER.createPacket(PacketType.Play.Server.SPAWN_ENTITY);

which methods do I need?
for these:

        WrapperPlayServerSpawnEntity entity = new WrapperPlayServerSpawnEntity(packet);

        entity.setType(EntityType.ITEM_FRAME);
        entity.setUniqueId(UUID.randomUUID());
        entity.setEntityID(ID_GENERATOR.getAndIncrement());

        entity.setX(x);
        entity.setY(y);
        entity.setZ(z);

        entity.setObjectData(direction);
        entity.setYaw(YAW[direction]);
        entity.setPitch(PITCH[direction]);

how do I know which fieldIndex for example Type -> VarInt is?
is it 2? or 3?

or can I use packet.setMeta method?

[drowsy helm]

should just use mojang mappings

[glass mauve]

nah

[glass mauve]

this correct for setting Type = ItemFrame
packet.getIntegers().write(1, ...);

[crude charm]

Do newer versions of spigot have a way to set the defense value of armour without giving it protection 1000000?

[glass mauve]

I can't find the method for Angles tho

[boreal sparrow]

I still can't warp my head around how to seperate worlds efficiently, should I create a new object for each world?

Like if I have an enum of gamestates, could I create a gameMap object that has it's own gamestate? I'm really confused

[crude charm]

What are you separating worlds for?

[boreal sparrow]

for minigame maps

[crude charm]

Could take the hypixel approach and have minigame servers

[hushed pawn]

Bungeecord is the most effective way i believe

[boreal sparrow]

yea i know servers are way easier, but is there a way to do this with worlds?

[crude charm]

ofc there is a way to do it all in one world as well

Just depends what u wanna make and stuff

if its like uhc or smth then u kinda need multiple servers for performance

if its tnt tag then u can do it on one

assuming ur code isn't shit

[boreal sparrow]

Yes, all I want to do is handle all the events/game states for the worlds seperatly. But I also want to minimize duped code, what's the best way of doing this?

[crude charm]

For gamestates, enums

what is the minigame?

[boreal sparrow]

a simple minigame that has parkour, and two players with bows trying to shoot them off, I already got that mostly sorted, but now I need to add more maps so the whole thing kinda breaks down

there is only one world, (ie. one game at a time, dumb, I know, but it's a really small server)

[crude charm]

It's probs because you hardcoded alot of it around one map

I can't see your whole project so idk how to help you but you should be able to figure it out yourself, just use enums for gamestates and you can have a var in the enum for the world or smth and use that

[boreal sparrow]

that might work

thanks for your help

[crude charm]

All good

[echo basalt]

you want to make a fake itemframe map?

[glass mauve]

yea but I think I got it

[echo basalt]

you gotta send like 3 different packets

[glass mauve]

nah 2

SPAWN_ENTITY + ENTITY_METADATA

[echo basalt]

MapItemData too

to render the map

[glass mauve]

and for destroying:
ENTITY_DESTROY

[glass mauve]

player.sendMap(view)

[echo basalt]

otherwise you'll have an empty itemframe

I guess that can work

[glass mauve]

I alr. got it to work for 1.18 but 1.19 packet wrapper doesn't work anymore

[echo basalt]

https://sourceb.in/fFnf4LhuJB

Mine's funky

[glass mauve]

you send the mapPacket yourself?

can't I get the Array of VarInt EntityID's using
packet.getIntegerArrays().write(0, ...);

or is it IntLists?

[hushed pawn]

Automatic creation of different runnables for every player, and deleting it when they leave, is it good idea?

[lost matrix]

The nms packet contains an IntList

[lost matrix]

No. Create one runnable and add/remove players to/from it.

Version?

And you are using ExactChoice for ingredients?

[glass mauve]

ok i tried intarray ._.

[lost matrix]

Well then its a simple ingredient missmatch. Make sure to never reload your server because it almost always breaks something

[hushed pawn]

Okay, i have list of uuids of players that should be added to some runnable, how exactly i have to do it?

[lost matrix]

Why do you need a hashmap for this??

[boreal sparrow]

Ok this is a really dumb question, but I've gone to StackOverflow at least 6 times now, why can't I call this?

public class WorldManager {
    public List<String> worlds = new ArrayList<String>();

    public void setWorlds(List<String> worlds) {
        this.worlds = worlds;
    }
    
    setWorlds() //Can't call? Invalid method declaration return type required??
}

[lost matrix]

And i hope that you are always cloning the item and never use the original, right?

[lost matrix]

You are trying to run code in your class again...

[echo basalt]

1 - you're not calling the method inside of any code block
2 - your method has params which you are not filling

this isn't python

[boreal sparrow]

damn thanks

[lost matrix]

An i hope that this "item" is never given to a player. Only a clone of it.

[echo basalt]

bruh hypixel wannabe hackers are forking my skyblock core thinking it's the real shit

mutability

[lost matrix]

What are you trying to do?

[echo basalt]

well you gotta save your recipes

it adds to the recipe iterator thing

the server doesn't save recipes

it just has a registry that fills up with contents during startup

[lost matrix]

No. You are adding it on every restart no reason to save them.

[echo basalt]

make your own config or something yeah

[hushed pawn]

I have option to hit player from certain location
I need to hit certain players when they get close enough to that location so i have to check player location every tick

[glass mauve]

huh idk why but my packet spawns a mob (ally if thats the name of the one new mob) instead of item frames ._.

[lost matrix]

Thats quite expensive but you will see.
Well then just create a runnable that has access to all players and all locations that need to be checked.
No need to add players to the runnable because you can just iterate over Bukkit.getPlayers()

[echo basalt]

entity type id

calling EntityType.WHATEVER.getTypeId returns the wrong id when it comes to protocol

you either mess with the registry or hardcode it

[glass mauve]

45

[echo basalt]

hm

You're using protocollib right

[glass mauve]

yep

[echo basalt]

show code

[glass mauve]

    private static void setItemFrameData(@NotNull PacketContainer packet, int entityID, double x, double y, double z, int direction) {
        packet.getIntegers().write(0, entityID);
        packet.getIntegers().write(1, 45);
        // packet -> set unique id

        packet.getDoubles().write(0, x);
        packet.getDoubles().write(1, y);
        packet.getDoubles().write(2, z);

        packet.getIntegers().write(4, direction);
        packet.getIntegers().write(3, (int) (YAW[direction] * 256.0F / 360.0F));
        packet.getIntegers().write(2, (int) (PITCH[direction] * 256.0F / 360.0F));
    }

[echo basalt]

yeah that's not gonna awork

[glass mauve]

whats wrong

[echo basalt]

are you using SPAWN_ENTITY or are you using SPAWN_ENTITY_LIVING?

[glass mauve]

SPAWN_ENTITY

[echo basalt]

pass an entitytype

and not the type id

[echo basalt]

the entitytype gets converted to type id when writing

packet.getEntityTypes() ...

[glass mauve]

like this?

[echo basalt]

Yeah

[glass mauve]

is it field index 0?

[echo basalt]

yeah

[glass mauve]

ty let me test

[echo basalt]

you only need to pass a type id for SPAWN_ENTITY_LIVING

type thing

[glass mauve]

but wait are my indexes messed up cause entityID

[echo basalt]

somewhat

0 -> id
1 -> xVel
2 -> yVel
3 -> zVel
4 -> pitch?
5 -> yaw
6 -> data (entity type specific)

[fiery prairie]

in PlayerQuitEvent, if i set the player's health to 0 using setHealth, will it actually kill him? well since he logged out already

[echo basalt]

yes

[glass mauve]

why xVel etc arent these short?

[echo basalt]

well

the packet stores it as ints internally

but serializes it as shorts

xRot and yRot are serialized as bytes

still stored as int

[fiery prairie]

okay, and if someone was during combat (more like the built-in system of minecraft) would the death message still be like the person died because the other guy killed him or is it just gonna be "Player died."?

[echo basalt]

Try it and see

[glass mauve]

and how do you found out this indexing?

[fiery prairie]

alright, thanks

[echo basalt]

decompile the nms packet

[glass mauve]

🤡

[echo basalt]

protocollib just writes the fields

I have a guide that does a basic demo on how it worky

https://www.spigotmc.org/threads/understanding-protocollib-packets.529392/

wrote it a while ago when 1.17 was the latest ver

[glass mauve]

but when I use getIntegers.write(); which index do I need? the same as nms stuff

[echo basalt]

starts from 0

and it's the order where it's declared in the class

[glass mauve]

with class you mean this? from top to bottom? thats what I did

[echo basalt]

wiki.vg doesn't reflect the nms format

but it's useful for cross-referencing unknown variables

wiki.vg matches this part

[glass mauve]

this shit so confusing

[echo basalt]

wiki.vg reflects the true protocol, and not how nms handles it

ProtocolLib just grabs the objects you're writing and uses reflections to write it to the internal nms packet "handle"

Let's take a basic example

and make our own bootleg packet

in pseudocode because I can't bother

[glass mauve]

np thanks :D

[echo basalt]

ClientboundWhateverPacket {

  x : int
  y : int
  z : float

  write(buffer) {
    writeLong(x)
    writeInt(y)
    writeFloat(z)
  }
}

wiki.vg will say:

• x is a long
• y is an int
• z is a float

ProtocolLib will say:

• x is int id 0
• y is int id 1
• z is float id 0

[glass mauve]

ok so if I want to know index I need to decomp and look myself

[echo basalt]

yeah

[glass mauve]

there is no list online?

why not?

[echo basalt]

wiki.vg is the list

but it reflects the contents that are serialized and not the fields in the packet class

It's also quicker to decompile

you can just middle-click on intellij

or Ctrl+B iirc

[glass mauve]

but wiki doesn't give me index

[echo basalt]

wiki.vg's index is top-to-bottom

I honestly just use wiki.vg to see what packets I can mess with

There is a way to create packets the wiki.vg way

and it's to like

create a bytebuf

write the contents with the wiki.vg format

and use the bytebuf constructor

Example

ByteBuf byteBuf = Unpooled.buffer();
FriendlyByteBuf buffer = new FriendlyByteBuf(byteBuf);

buffer.writeVarInt(123);

PacketWhatever packet = new PacketWhatever(buffer);
sendPacket

tho it's hacky

and I've only seen it use in a plugin once

[glass mauve]

ok thank you very much, let me try to

[fiery prairie]

in EntityDamageByEntityEvent, e.getEntity is the entity who attacked and e.getDamager() will be the one who got attacked, right?

or is it the exact opposite

[echo basalt]

getDamager is the damager

getEntity is the victim

[fiery prairie]

thanks

[glass mauve]

this is kinda wrong I think

this should work if yours would be true but I get this error:

uhh it's version specific

just check the nms packet

[glass mauve]

oh ok

where can I find it in my ide?

nvm found

nvm I found the spigot api but where can I find this nms stuff

[echo basalt]

yeah you importing spigot-api

[glass mauve]

spigot-api

[echo basalt]

change it to spigot

if it doesn't recognize, run buildtools

or you can just run mojmappings

[glass mauve]

ok ty

[echo basalt]

https://sourceb.in/5ZLgfu6UyK

mojmappings build.gradle

add

pluginManagement {
    repositories {
        gradlePluginPortal()
        maven { url = "https://repo.papermc.io/repository/maven-public/" }
    }
}

to your settings.gradle to access it

and change the version as well

[glass mauve]

should I copy this?

[echo basalt]

if you want to

it uses paper tho

[glass mauve]

no I want to stay with spigot,
I actually started with PaperMC for this project but I wasn't sure if spigot server could use paper plugins

[echo basalt]

they can for the most part

if you want to stay with spigot, change spigot-api to spigot

and maybe run buildtools

you'll have obfuscated nms

which is a pain but I'm used to it

Then the packets will be like PacketPlayOutWhatever

[glass mauve]

ok and where can I find it in nms

nvm it's in net.minecraft.network.protocol?

[opal juniper]

network

yes

[glass mauve]

and why is it called nms?

[opal juniper]

its the package, net.minecraft.server - initials are n.m.s
