[torn oyster]

Is there a way to hide an npc from the player list without removing its skin?

[iron glade]

I solved it thanks to his input

[haughty idol]

            p.spawnParticle(Particle.ASH, p.getLocation(), 50);
        }, 1L, 100L);``` so this would run every tick for 100 ticks

right?

[iron glade]

This would start after 50ms and run every 5 seconds

[haughty idol]

it doesn't work

oh

[haughty idol]

ohh

[eternal night]

timers don't stop unless explicitly cancelled

[haughty idol]

ah

okay

[eternal night]

1L

[iron glade]

1L = 50ms

[eternal night]

is a tick

^

so I guess ~50ms

[haughty idol]

how do i get the taskId?

[eternal night]

preferably don't and use the returned bukkit task instance

which has a cancel method on it

[haughty idol]

ah

[eternal night]

if you just wanna execute something 100 times you could just:

final AtomicInteger counter = new AtomicInteger(0);
scheduler.runTaskTimer(plugin, task -> {
  if (counter.getAndIncrement() > 100) {
    task.cancel();
    return;
  }
  ... do your thing
}, 1L, 1L)

not, I just wrote this off the top of my head

so

[torn oyster]

what packet would i use to remove an NMS player from someone's view

[eternal night]

that might not be valid java code xD

[hasty prawn]

20 ticks/second, 1000ms = 1 second, so 1 tick is about 50ms.

[iron glade]

yes

[torn oyster]

it's an nms player

not a real player

[eternal night]

send an entities destroy package

[torn oyster]

ClientboundRemoveEntitiesPacket?

[eternal night]

ClientboundRemoveEntitiesPacket

yea

notably don't ever send that to the player itself xD

that will completely fuck the client up

[dawn hazel]

pretty sure you dont need to use atomicinteger for that

[eternal night]

a normal int won't work

as you are using it inside a lambda, which requires captured variables to be effectively final

[torn oyster]

is it ClientboundRemoveEntitiesPacket(EntityId)

[eternal night]

yea

[torn oyster]

okay cool

[iron glade]

can use a one size int array

that's my goto

[eternal night]

there is a constructor that takes an int varargs

[quaint mantle]

Hey, how can I set up NMS?

HashMap?

[wise leaf]

Could you not just use an array?

Like an array of tuples

[quaint mantle]

So a hashmap

[wise leaf]

Well then if you need that a hash map is probably the best option

[quaint mantle]

Then a hashmap inside a hashmap

no

[wise leaf]

Sounds like you are trying to implement an ORM

Why not just use an ORM lib

[quaint mantle]

An ORM basically helps you do stuff with a database

[wise leaf]

Object Relational Mapping, its what you are trying to do

Links data from a database to objects

so that you can interact with data on your database progmatically without having to handle all the queries yourself

[quaint mantle]

Yea

[wise leaf]

Java has millions of them

Hibernate seems to be the most popular one, not sure if its any good though haven't touched java in quite some time

[haughty idol]

it keeps saying that it can't delete this createdfiles.lst file

and if i delete it normally its fine

but its really annoying

[lost matrix]

Are you trying to delete it programmatically?

[ivory sleet]

Its convenient thats all

there is a kt one which is much better iirc

but thats for kt

[snow lava]

someone knows how to add an id to a block? it's because i created a custom block and i need to identify it to create some functionalities.

[lost matrix]

You cant have custom blocks in minecraft yet

[snow lava]

i created one with mob spawners and armorstands

[lost matrix]

Only through some hackery

[paper viper]

You could create a "fake" ID by using PDC

[lost matrix]

Ah

Spawners are persistent data holders. So just use the pdc.

[snow lava]

yeah, but that works as an nbt tag?

[haughty idol]

uh no

[lost matrix]

Yes the pdc is stored in the nbt tag

[snow lava]

but i tryied to use it and i check if the tag was added to the block and it wasn't there

[lost matrix]

You need to update the BlockState after editing the pdc

[snow lava]

can i add a tag directly like: tiledata.setBoolean("Customblock", true);?

[lost matrix]

Sure. You can also just add an id. data.set(someKey, PersistentDataType.INTEGER, 20)

[reef brook]

How can I relocate the dependencies of my dependencies without writing them all? Because it's endless. Or is there an option to relocate everything? With maven

[lost matrix]

If you relocate your dependencies then the relocation is transitive.

*If the relocated dependency shades its content

[reef brook]

I have relocated a dependency but its dependencies are not

                        <relocation>
                            <pattern>net.kyori</pattern>
                            <shadedPattern>${project.groupId}.${project.artifactId}.dependencies</shadedPattern>
                        </relocation>

        <dependency>
            <groupId>net.kyori</groupId>
            <artifactId>adventure-platform-bukkit</artifactId>
            <version>4.1.2</version>
        </dependency>

maybe I relocated it wrong

[lost matrix]

You have the maven shade plugin set up, right?

[snow lava]

i'm asking because the tag is added but when i tryied to check it, it's not there

[lost matrix]

#help-development message

[reef brook]

yes

[opal juniper]

maybe show the whole pom

[lost matrix]

Well your pattern only shades net.kyori
Look into the kyori dependency and see under which path it shades its own dependencies

Maybe its different

[reef brook]

it's gradle and i don't know how shade work on it
https://github.com/KyoriPowered/adventure

[lost matrix]

Its done with the shadow plugin. Let me take a quick look.

[reef brook]

https://github.com/KyoriPowered/adventure-platform
maybe it's here idk

[lost matrix]

What problem do you have anyways? Because you should not need worry about this in the first place. Its a really weird issue.

[reef brook]

my plugin interferes with another one because of a kyori adventure dependency that is not relocated

[reef brook]

should i write net.kyori.* ?

[thin delta]

Alright boys... I fixed my eclipse and now I have my project as a Maven project. I need in export the jar and include this in it as a dependency. Can someone walk me through it?

[snow lava]

this didn't work

[lost matrix]

update(true)

[snow lava]

i made it work but it overrides all my nbt tags

[glossy venture]

pdc is goofy

use nms 😎

nbt

[snow lava]

yeah

but i tryied that but i couldn't

[snow lava]

how would you do it

[eternal oxide]

Keys may only contain lowercase alphanumeric characters, periods, underscores, hyphens, and forward slashes.```

[glossy venture]

get the nms world with like reflection, get the tile entity at the blocks position and get the nbt tag

[eternal oxide]

Your Key is invalid

[glossy venture]

nbt can have anything as a key i think 😎

[eternal oxide]

PDC works just fine and shoudl be used over NBT

[snow lava]

but i made it work but all my tags were override

[torn oyster]

hey elgar, how do I remove the NPC from the tab list without removing its skin?

[reef brook]

shade net.kyori

[torn oyster]

i believe you told me yesterday how to remove them from tablist but it removes their skin

[eternal oxide]

Skins shouold be maintained so long as they have been spawned on the client

[glossy venture]

no 😎 you can create nbt tags which reference objects at runtime but convert to compounds when saved 😎 i did that 😎

[torn oyster]

that isn't the case unfortunately

should I try delaying the remove thingy a few ticks?

[eternal oxide]

you could try it. I've played with skins/names and updating packets but I've not tested in depth

[torn oyster]

okay

[snow lava]

here i tryied with nms and here is the result:

[glossy venture]

looks good right

[snow lava]

at first the tag exist but when i check the block the tag disapears

[glossy venture]

wait

im pretty sure tile entities dont store tags

at runtime

so use pdc

the chunk pdc

or a map at runtime and save it when the chunk is unloaded

[snow lava]

with pdc the tag is stored

but all my other tags disapear

[eternal oxide]

a TileEntity retains its PDC data between sessions. Can you explain your issue again as I've not read that far back.

what other tags? Other PDC tags?

[snow lava]

here is the code:

[snow lava]

nms tags

[glossy venture]

those dont work with tile entities

they dont store NBT for performance and memory reasons

[eternal oxide]

you are trying to use NMS tags and PDC at the same time?

[glossy venture]

they only save to and load from nbt

just like other entities

right?

[glossy venture]

did it work without using the pdc?

[snow lava]

yeah

[eternal oxide]

first, change your PDC key to a valid key

you can;t use upper case letters

[snow lava]

all my nms tags store as spected

[eternal oxide]

that is a PDC tag you are adding. Lower case only

[snow lava]

yes

but i have more tags, if you want i can show all the code

[eternal oxide]

That tag will not work correctly as your key is invalid

Read teh javadoc on how to format a NamespacedKey correctly https://hub.spigotmc.org/javadocs/spigot/org/bukkit/NamespacedKey.html

[haughty idol]

how would i make the player disappear along with their armor, but still be able to be hit (with packets)

[snow lava]

i can't understand why is not a valid key

[eternal oxide]

a key must be ALL lower case. No upper case characters

[snow lava]

ahh ok

but can i use nms tags an pdc at the same time?

[eternal oxide]

It should be possible, but not sure why you would want to.

[snow lava]

here works the pdc

but all the other tags were gone

[haughty idol]

bump

[snow lava]

My code: https://paste.md-5.net/afoquzoban.cs

[haughty idol]

how the hidePlayer works is that it makes the player invincible too

:/

because i tried it and nobody can hit me :/

[eternal oxide]

all of those NBT values you are setting and available via the API

[haughty idol]

they used aoe attacks :/

one even autoclicked and couldn't hit me

[eternal oxide]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/block/CreatureSpawner.html

[haughty idol]

i heard that i have to do it with packets

[snow lava]

yes, but you can't modify the entity inside

[eternal oxide]

You don;t seem to be setting anythign which is not exposed by the API

I'll be away for 15 mins

[balmy valve]

Anyone know how to summon a firework that doesn't have any of the white firework particles in it?

will give more context in a second when I have the information easily showable

the 2 important things in that photo are the firework in the background and the chat showing the firework meta

in the firework you can see that there are white particles mixed with the reds

but in the meta no such explosion exists

[haughty idol]

i think you have to edit the meta of the fireworks

[balmy valve]

Anyone know how I can remove those particles?

[haughty idol]

oh

my bad

[balmy valve]

lol np, Im manually setting the firework meta alr

[torn oyster]

how come my NMS fake player's skin isn't double layered?

[eternal oxide]

You didn;t send the player meta packet

if you are just using packets you send java new ClientboundSetEntityDataPacket(npc.getId(), npc.getEntityData(), true)If they exist in the World you instead wrap the ServerPlayer in yoru own class and set java this.getEntityData().set(Player.DATA_PLAYER_MODE_CUSTOMISATION, (byte) 0xFF)

[iron glade]

Someone's got an idea on how to exctract chat color from a string?

Like if the string is &6Some string I only wanna have the &6

[delicate lynx]

probably regex is your best bet

[thin delta]

Alright boys... I fixed my eclipse and now I have my project as a Maven project. I need in build the jar and include this in it as a dependency. Can someone walk me through it?

[lost matrix]

Why?

[fervent gate]

Is there a way to create a mob with a nametag that has multiple lines? I've tried working with scoreboards but that doesn't work on mobs apparently.
Cannot resolve method 'setScoreboard' in 'LivingEntity'

[iron glade]

I thought about it and I actually need the last used color in a string (if there's any)

e.g. &6Some fance &4String should return &4

[strong parcel]

Hey, I am trying to give a Player_Head a custom texture, but I am having issues with the dependencies. The tutorial I am watching told me to replace "spigot-api" with "spigot" in the pom file, but I get an error saying it can't find that dependency. Does anybody know what I am missing?

[opal frigate]

Install that version with BuildTools

[balmy valve]

bump ^

[opal frigate]

Probably just 1

[strong parcel]

Oh, I had the wrong version specified. Thanks!

[opal frigate]

Well it all depends what you want to do

If it’s basic then why use 2 listeners?

[lost matrix]

    @EventHandler
    public void onEvent(SameEvent event) {
        checkA(event);
        checkB(event);
    }

    private void checkA(SameEvent event) {}
    private void checkB(SameEvent event) {}

[strong parcel]

So Intellij is letting me import GameProfile now, but when I compile I get an error saying "cannot access com.mojang.authlib.GameProfile"

[eternal oxide]

Using Maven?

[strong parcel]

Yes

[eternal oxide]

Then build using Lifecycles Package, not artifacts

[strong parcel]

I used install from Lifecycle

[eternal oxide]

?paste teh full error then

[undone axle]

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

[strong parcel]

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

[eternal oxide]

You are using the wrong version for your target java version

what spigot version are you building against?

[strong parcel]

I think I was building against 1.18.2. Is there a way I can confirm?

[eternal oxide]

In that case you don;t need GameProfile at all

[strong parcel]

Oh, what would I use instead?

[eternal oxide]

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

All spigot now, no Mojang

[strong parcel]

Thanks!

[quaint mantle]

how can i make a different thread every chunk?

for prison enchants

[eternal oxide]

why would you want a new thread for every chunk?

In PlayerMoveEvent, compare chunk in getFrom and getTo. If not the same, remove old chunk enchants and apply new chunk enchants.

[main dew]

I can get block data after click in PlayerInteractEvent?

[quaint mantle]

because better performance

since its looping hundreds of blocks

[eternal oxide]

It won't be "better performance"

[main dew]

For blocks like trapdoor flower_pot etc.

[quaint mantle]

but it would be tho :/

[eternal oxide]

why are you looping hundreds of blocks?

[quaint mantle]

looping the blocks on 1 thread would cause lag

because prison enchants :/

[eternal oxide]

Yeah, no clue what a "prison enchant" is and no clue why you need to loop hundreds of blocks

Spigot is a state change system. you don;t do anything unless you are triggered

[quaint mantle]

like this

its looping alot of blocks, which give you money

[eternal oxide]

No clue what that is

[quaint mantle]

;-;

[eternal oxide]

its a screenshot but tells me nothing

do the blocks change?

[quaint mantle]

yes

they would change to air and give money / tokens

but if i do it on 1 thread

it'll lag

[eternal oxide]

take a snapshot and process it async

jump back sync to make any changes

[quaint mantle]

a ChunkSnapshot?

alr

wait, so how would i make a thread per chunk?

im a little confused

[eternal oxide]

You don't. That would be crazy

[quaint mantle]

so what would you recommend?

just a snapshot

[eternal oxide]

yes

generally reading blocks Async will not cause issues, but you must be Sync to make changes

[quaint mantle]

yeah

[eternal oxide]

so you do all your processing Async, then jump back sync to make changes

[quaint mantle]

👍

[tender shard]

I got banned from paper now too

[eternal oxide]

lol

[iron glade]

why

[tender shard]

wait

[main dew]

I can get block data after click in PlayerInteractEvent?
For blocks like trapdoor, door, flower pot etc

[tender shard]

sorry, only kicked

but I dont wanna "shame anyone" so yeah

there was some disagreement with a person who had kick perms and me, and then I got kicked

lets not go into details

[iron glade]

bruh

[humble tulip]

You do you

Di is cleaner tho

[echo granite]

singleton is cleaner lol

Always use DI except for one case which is passing the plugin's instance, Use a singleton for that.

Bukkit doesn't allow you to create an instance of your main class, so there is only one - therefore using DI for that is just stupid and takes more code.

[ivory sleet]

testability

reusability

robustness

maintainability

modularity

logger is fine for instance

(since you test loggers by appending them anyway)

and no singleton is not cleaner

singleton is less verbose probably

but it is definitely by all means less cleaner

yeah

maintainable refers to the future work you have to put in

modular refers to how isolated different functionalities of your plugin is

robustness refers to how resistant your code is towards changes

testability refers to how easy your components are to test, in terms of unit tests, integration tests, sys tests and acceptance tests

reusability refers to how easy a component of your system is to reuse

DI means your components depend on dependencies at type level, for instance a constructor is just a function that takes a set of types and returns a type

this allows us to depend on high level types, interfaces that is

and then they can be mocked for testing

when we have classes that depend on abstraction we gain dependency inversion for instance

and is a SOLID principle

anyway Pvbble

we can look at it from the other perspective

what are the disadvantages of mono/poly state

oh poly state is just the term for static state

mono state refers to when you have like a single static state within bounds of a class

in other words, the disadvantage of static and singletons

first you typically conclude a design where a class depends on your singleton

[shadow zinc]

If runtime.maxMemory() represents the Xmx value, then what is the runtime.totalMemory() method represent?

[ivory sleet]

that leads to that every instance of said class depends on that singleton

which in other words make the design tightly coupled

iirc current memory allocated kytdk

no i mean the classic way

[shadow zinc]

yeah im confused

[ivory sleet]

//inside class
var instanceField = Singleton.instance();

[shadow zinc]

I found this but I still don't understand it

[ivory sleet]

no not really

if you have it through the constructor then first of all half of the meaning concerning singleton disappears as you cant have them lazily

and secondly the class becomes mockable through mockito

we also see what the class depends on more explicitly

no

the point of a singleton is to provide a single instance of a class as well as a global access point to that instance

by definition

[lost matrix]

What exactly do you not understand?

[shadow zinc]

whats the difference between max and total?

[lost matrix]

total is used + reserved

max is the max allowed for this jvm instance

But the jvm does not reserve all its memory from the beginning.

[ivory sleet]

no

[lost matrix]

You can do that with jvm args (Xms) and you also should do that if you run a mc server.
In this case total == max

[ivory sleet]

used in static context has inherently nothing to do with singleton

but it does extend its usecase sure

[balmy valve]

bump cause still lost on this, (see messages below replied one for the rest of the context)

[tidal yacht]

there is have an event to check if player is walking or not?

[shadow zinc]

so if I wanted to get the memory to player ratio I would use max memory since it includes all the possible memory that could be used by the jvm?

[lost matrix]

What are you trying to do?

[ivory sleet]

the entire point of static singleton was to have them lazy because they may not actually be called at all thus saving some memory etc

that was back in the days when we didnt have obscene amounts of memory

[lost matrix]

What do you mean "memory to player ratio"

[shadow zinc]

memory/playercount

[tidal yacht]

I want if player is walking, some method will called

[lost matrix]

Used or max

[drowsy helm]

PlayerMoveEvent

[shadow zinc]

yeah probably max

[lost matrix]

There is no method for when a player starts/stops walking because movement is done stateless.
Whats the overall idea?

[lost matrix]

I still dont understand your plan. Do you want to know how much memory you can "use" per player currently?

[shadow zinc]

yes

[lost matrix]

Well then its max.

[tidal yacht]

i don't understand with "done stateless"

[lost matrix]

What do you want to achieve?

[tidal yacht]

I want if player start/stop walking, something happened

[lost matrix]

https://tenor.com/view/frodo-keep-your-secrets-alright-then-lotr-gif-12907121

[drowsy helm]

yeah what though

[tidal yacht]

but, can someone tell me about PlayerMoveEvent?

[drowsy helm]

what is something

[ivory sleet]

lyey basically, the whenever the player moves just a little bit that event gets called

[drowsy helm]

even head movement

[ivory sleet]

during the time player moves from x to y the event is called continuously in principle

[tidal yacht]

oh, I understand

will it working to check if player is sprinting with isSprinting() in during the player moves?

[drowsy helm]

yep

[tidal yacht]

ok, thanks

[ivory sleet]

oh yeah pvbble ping me when u're done with ur little essay

:]

(hopefully I can answer it satisfyingly)

myes

first and foremost, you rarely do use singletons in static context (if you have a robust design)

then just because a single instance of the class is what fits your system as of the present moment does not mean you should allude towards the singleton design pattern

the issue is that static singletons are usually used like this (which they should be):

class CassandraDatabase {
  static CassandraDatabase instance;

  static CassandraDatabse instance() {
    if (instance == null) {
      synchronized (CassandraDatabase.class) {
        if (instance == null) instance = new CassandraDatabase();
      }
    }
    return instance;
  }
}

class SomeFunctionality {
  void performWork(DatabaseType dbType, Query query) {
    switch (dbType) {
      case DatabaseType.CASSANDRA -> {
        CassandraDatabase.instance().fetch(query);
      }
    }
  }
}```

now ofc we can use it like:

record SomeFunctionality(CassandraDatabase database) {

}

//or lazy
record SomeFunctionality(Supplier<? extends CassandraDatabase> database) {

}

the last one is just unnecessarily complicated but is sometimes needed, the former gets rid of lazy initialization

alr good luck

but like I hope you see, if we use SomeFunctionality(CassandraDatabase database), the dependency becomes transparent through out the class

and we depend on a type rather than a single unit

which makes it a bit more robust if we want to reuse it

lets say with another instance of that database class which is configured differently

it does sound a bit nerdy and useless, but much about good software practices has turned into writing code that is extendable to the degree that we can change it without causing the entire system to fall apart

[reef lagoon]

?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!

[quaint mantle]

Hello everyone, I have a question regarding packets

The "minecraft:register" and the corresponding "unregister" channel
Do they actually have an effect inside the server?
Or are they for me to query?

[lost matrix]

https://wiki.vg/Plugin_channels#minecraft:register

Its only used to register custom channels if both parties support it

[quaint mantle]

Yeah I read every single source I could gather
Several forum entries, this entire Wiki and even the Dinnerbone posr
But it's still quite unclear to me what's actually happening

So is this some sort of handshake?

[lost matrix]

Nope. Just a normal channel where you can send packets which tell the other party that you want to register a new channel
and that it should listen to this new channel for packets.

But this has to be supported by the receiving side. Which is not the case for the notchian client.

Wait let me double check on that last part

[worldly ingot]

It's basically custom packets

It's just an arbitrary stream of byte data

[quaint mantle]

Yes of course, if either doesn't support it, packet sending would be useless to begin with 😅
I am just checking on the semantics
If my client sends the registration with the channel name I want
How do I respond on the server
Do listeners listen on the register channel so I can act upon it and send a corresponding registration packet back?

[ornate patio]

What do you guys think the best approach for this is:

I need to generate a randomized 6 character code (made from numbers and letters) often, but I also need to make sure it's unique. How do I ensure that the code is unique in the most efficient way possible?

I was thinking of just generating a code normally and if already exists in a giant list of used codes, generate another. But this doesn't sound like a good idea in my head

(When a code is generated, it'll expire after 2 minutes, in case you're about to say that I'll run out of possible codes eventually)

[lost matrix]

Yeah but the client has no logic for them. So it doesnt matter if the notchian client acks the registration because its useless information to him anyways.

[worldly ingot]

There has to be a mod that does something with it on the client

This is where Fabric or Forge comes in

[quaint mantle]

That doesn't matter
I am asking in a mod context, obviously the client won't care (if nothing tells it about a new channel)

[worldly ingot]

Either one of two has to send the register message

[quaint mantle]

All I was wondering is if I send this registration packet, how do I recognise this?
Do I add a listener to the register channel?

[worldly ingot]

If one sends a register, they both understand it exists and can send outgoing or receive incoming messages

[lost matrix]

Calculate the collision probability and multiply by the severity of the collision to make a decision on that.

[ornate patio]

huh

[worldly ingot]

For Bukkit, we have a messenger class that can register an incoming channel

[ornate patio]

collisions?

[lost matrix]

http://apppm.man.dtu.dk/index.php/Impact_and_Probability_in_Risk_Assessment

[quaint mantle]

Ah, so either sends it and it's automatically open for both

[worldly ingot]

Yes

[quaint mantle]

Ah, that's where the Dinnerbone post confused me with "one sends it, the other does the same"

So I just need to do it one way

[ornate patio]

oh boy

[lost matrix]

Do you allow only small letters?

[ornate patio]

Doesn't matter

I could do small letters only too

It doesn't even have to be 6 characters- I just don't want it to be a UUID, I need the code to be easily copy/pasted or legible to any user if you know what I mean

[lost matrix]

Ok so then a-z A-Z 0-9
= 62 variations per slot.

Your word is 6 slots long meaning there are a total of 62^6 cominations

[ornate patio]

mhm

56800235584 possibilties

maybe i shouldnt worry about it?

[lost matrix]

Which means you can safely generate them for hours without a collision

[ornate patio]

okay

so i have a reasonable way to say that i'm too lazy to add some protection for that

thanks

[lost matrix]

Thats also what UUIDs do btw. They are so unique that once generated are very safe

So i would just use UUIDs...

[ornate patio]

mhm i figured

I dont wanna use UUIDs in this case though

[ornate patio]

its a code someone is gonna copy paste somewhere

[lost matrix]

Which code isnt?

[ornate patio]

I mean like

UUIDs just look ugly

and not very professional (to see in an application)

[lost matrix]

What...

[ornate patio]

i dont mean using them

im saying like

[lost matrix]

UUIDs are used in enterprise applications all the time

[ornate patio]

i know i use them all the time

what i mean is

[lost matrix]

its the gold standard for ids

[ornate patio]

it looks very ugly to non-programmers i could say

[lost matrix]

Its as professional as it gets

[ornate patio]

💀 i know

I use it all the time for the internals of my app

but

[quaint mantle]

Oh and, now when I send this from the client
Will the server register the channel for me or will I still have to use registerXPluginChannel?

[lost matrix]

Ah i see what you mean

[ornate patio]

what I'm working on right now is supposed to be a code

that end users will see

and use

[lost matrix]

You dont want ids you want something exposed to the user

[ornate patio]

mhm

[worldly ingot]

You'll have to register an incoming plugin channel from Bukkit

That's more or less a Bukkit thing though

[quaint mantle]

Hmm ok, that begs the question why I even need to send a register packet then if I register the channel myself

[worldly ingot]

Right, you don't. What modding framework are you using on the client?

Fabric and Forge handle those both for you

Here's an example of how I handle client-server communication for VeinMiner:
https://github.com/2008Choco/VeinMiner/blob/master/veinminer-bukkit/src/main/java/wtf/choco/veinminer/network/BukkitChannelHandler.java
https://github.com/2008Choco/VeinMiner/blob/master/veinminer-fabric/src/main/java/wtf/choco/veinminer/network/FabricChannelRegistrar.java

(this being Bukkit and Fabric)

[quaint mantle]

I am planning to target both of them
So I guess I will just ignore the register/unregister packets altogether

[worldly ingot]

Yeah. With Fabric they use the ClientPlayNetworking class to register incoming listeners, and you can use that same class to send outgoing messages

Forge has a whole network protocol API around it as well

(I actually really like and prefer Forge's API)

[quaint mantle]

So I guess the way I will do this
Is trying to send a packet from the client to ensure the Plugin is installed and if not, the mod is internally disabled
And the other way around, it's probably simpler
I don't know though, the server will still send a packet though to the client?
And be it into the void of a notchian client?

I guess I could send an ACK from the client to queue available clients so the server knows to where it cam send messages

[scarlet creek]

How can you spawn a villager with a profession but not allow trading with the villager?

[long zephyr]

cancel the interact event

[scarlet creek]

Ah ok

[knotty meteor]

How do i let my armorstand float on water?
Because if i put gravity on false i cant ride it anymore..

[tall dragon]

put it in an invisable boat 😄

[knotty meteor]

How can i do that?

[tall dragon]

spawn the boat

[reef brook]

How can I relocate the dependencies of my dependencies? With maven

[tall dragon]

then call EntityBoat#setInvisable(true);

[knotty meteor]

Thank you! :D

[reef brook]

currently I put in my project the dependencies of my dependencies and relocate them but it is endless because they all have dependencies

[chrome beacon]

https://maven.apache.org/plugins/maven-shade-plugin/examples/class-relocation.html

[reef brook]

I already have this link open but it doesn't help me

[chrome beacon]

What part do you need help with?

[reef brook]

I would like to know how to relocate an entire depencency

i have this

        <dependency>
            <groupId>net.kyori</groupId>
            <artifactId>adventure-platform-bukkit</artifactId>
            <version>4.1.2</version>
        </dependency>

and this

                        <relocation>
                            <pattern>net.kyori</pattern>
                            <shadedPattern>${project.groupId}.${project.artifactId}.dependencies</shadedPattern>
                        </relocation>

but adventure dependencies like kotlin are not relocated

i've been looking for days and I can't find a solution

[chrome beacon]

Simply add the other relocations

[reef brook]

lol, adventure has multiple dependencies
and each dependency of adventure has a lot of dependencies

it's endless

[chrome beacon]

Yeah

[reef brook]

manually it takes me 2 seconds to move the dependencies into the jar

there must be an option or something I did wrong in the pom

[reef brook]

i'm not sure about the pattern here

[tall jewel]

How to check if a player put a block on the grass or in the water?

[chrome beacon]

Listen to the block place event and check where it was placed

[tall jewel]

Yes, but, System.out.println(world.getBlockAt(loc).getType().name()); send me a block type, I placed, not water or grass

where Location loc = e.getBlockPlaced().getLocation();

[chrome beacon]

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

[tall jewel]

thanks a lot

[kindred valley]

Players put it from out of water or player puts it in water

[tall jewel]

I just want to prevent players from destroying water and grass by placing a block.

[eternal oxide]

and the getRelative(BlockFace.DOWN) to see if its placing on grass

[main dew]

I can get block data after click in PlayerInteractEvent?
For blocks like trapdoor, door, flower pot etc

[lost matrix]

One tick delay

Its always one tick delay...

[main dew]

It is good but I must check it instant and this is my problem

[lost matrix]

Instant means the block has not been used yet

[chrome beacon]

So what are you trying to do with the block data?

Why do you need it

[main dew]

Yea I know but I must check it

[main dew]

For Speed Builders

[brittle lily]

?paste

[undone axle]

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

[heavy swan]

Hi folks, does anyone know any code for an ItemStack I've made, I need to make it so that when I change the item's lore, name, or attribute, it also updates it in the player's inventory without having to have it again. Does any of you know how to do it?

[chrome beacon]

Then just check:
if pot empty -> right click with flower -> see if it's the flower you want

[main dew]

Speed builders check if buildings is perfect copy after BlockPlaceEvent and BlockBreakEvent but should check building is perfect after PlayerInteractEvent

[main dew]

So for all other blocks I must use other implementation? Trapdoor, door, flower pot etc?

[kindred valley]

Use pdc to contain all stacks. Then check if the item has that pdc if it is change all the qualifications. And reload

[errant narwhal]

hey

[chrome beacon]

Yeah or do what smile said

[errant narwhal]

is everyone know how to spawn Entity player using bukkit api??

[heavy swan]

Thank you!

[chrome beacon]

World#spawn

[errant narwhal]

impossiable

[chrome beacon]

Not really

[errant narwhal]

worldspawn can't spawn player/humanentity class

i have try

[chrome beacon]

Well for that you need NMS

Which means not using the api

[errant narwhal]

hmm how to make nms entity have mob AI?

[lost matrix]

Nope. Minecraft has no "Player" entity which is disconnected from a client.

[chrome beacon]

You use goals

[errant narwhal]

like it has player model but it is chicken

[lost matrix]

This will be really hard because you cant just spawn a player with ai goals.

[chrome beacon]

Yeah add all chicken goals to the player entity

[errant narwhal]

ok thank you

let my find about that

[chrome beacon]

There is ofc more work than that

Since you need to detach the entity from the player connection

[lost matrix]

Its way easier to just use LibsDisguises and disguise a custom entity

[chrome beacon]

Or just use Citizens

[kindred valley]

Yes it can fix all stuff

[errant narwhal]

bruh citizens api?

[chrome beacon]

Well yeah

And a good one

[kindred valley]

I found znpcs api better

[errant narwhal]

hmmm

i just want to make my npc can attack player and can be attack it look so hard

[chrome beacon]

If you want the NPC to attack

Use Sentinel

[lost matrix]

Just realized. hashCode actually uses the jvm memory address if no implementation is given.
So my take was still technically correct.

[reef brook]

manually it takes me 2 seconds to move

[cedar yoke]

how do i do 2 things in one case ->

here is what i want to do

case "up_right" -> worldY -= speed, worldX += speed;

i can only change the world y or world x but i need do to them both at once and making 2 case statements for "up_right" doesnt work

[eternal oxide]

not using lambdas case statements fall through

[quaint mantle]

Hey, what are InventoryView properties?

Alright, so, I need a way to differentiate between inventories. I was thinking of using some sort of id. What would be the best way to do this?

[cedar yoke]

like inventory you created with your code ?

[quaint mantle]

Yes

I create an inventory per player, so

[cedar yoke]

add inventory [name] = before the inventory code part

[flint coyote]

how can players do that? Rename an anvil?

I didn't know :o

That's actually cool. I might use it as a hidden easteregg name then. Thanks

[cedar yoke]

i see so you can make a inventory with the same properties use p.getname and save the inventory data for that player and load it every time the player uses /inv or something

[odd wedge]

Why?

That’s not what it’s used for

[west scarab]

hi. Is there any way to disable when interating with redstone ore it hngs to a glowing stae? it messages up my erver.

[cedar yoke]

p is nice and short, you can change it easily as well

[odd wedge]

Compare the inventories yourself

[odd wedge]

No

It’s not nice

We should be able to know what the variables are without looking at the code

Same goes for methods etc

[west scarab]

help lease..

[odd wedge]

E could be anything

[cedar yoke]

well if you read the code p is means player and its just shortened

[odd wedge]

Exception event etc

[odd wedge]

You shouldn’t need to read the code to know

[cedar yoke]

well if I do Object obj = .... then it isn't a problem

[odd wedge]

What if you have a huge method and you use p as a variable

[west scarab]

help

[odd wedge]

Should we read through that whole block just to know

[cedar yoke]

i think that's being too specific i mean how many people dont think Obj is short for object

[west scarab]

Yes I mean like in Java

I’ve tried disabling player interact event for red stone ore

But doesn’t fix it. At all

[odd wedge]

There should be a state for the block

[long zephyr]

hello ^^
Does anyone know how to avoid the shaking of the
ArmorStand when being teleported?
https://www.youtube.com/watch?v=M1rERVWm2Oo

[fervent gate]

Is there a way to create a mob with a nametag that has multiple lines? I've tried working with scoreboards but that doesn't work on mobs apparently.
Cannot resolve method 'setScoreboard' in 'LivingEntity'

[cedar yoke]

have you tried using array's ?

[fervent gate]

Arrays? How would that work in this case?

[west scarab]

⬆️

[odd wedge]

@cedar yoke

public void someMethod(final Plugin p, final Player p2) {

do something...


/* 300 lines of code
Hey this isn't working.
do smth with p and p2
*/
}```

How would anyone know what those are

Without looking at the whole method

[cedar yoke]

can you send me you code

[fervent gate]

sure

[west scarab]

any idea how to do it? I just need the block to stay the same. It fucks with my plug-in when it updates

[fervent gate]

It's basically the scoreboard copied from some spigot thread that explains them but swapped the player with my custom mob, which is a Zombie.

ScoreboardManager manager = Bukkit.getScoreboardManager();
Scoreboard board = manager.getNewScoreboard();
Objective objective = board.registerNewObjective("showhealth", "health");
objective.setDisplaySlot(DisplaySlot.BELOW_NAME);
objective.setDisplayName("/ 20");
yeti.setScoreboard(board);

I'll need to display a custom variable but I'll figure that out with the thread if the displaying works

[odd wedge]

Not sure. You could probably have a scheduler that sets the state when someone clicks on the block?

Something like that

[west scarab]

I tried but like

Every time that the block updated at all to a new block it fucks it.

[quaint mantle]

Well, what do I return in getInventory() then?

[cedar yoke]

List<String> name= new ArrayList<>();
name.add(" ");

[small current]

Arrays.asList

[odd wedge]

What are you trying to achieve? Checking your own custom inventories?

[quaint mantle]

Yep

Oh, thanks

[odd wedge]

public abstract class InventoryBase {
   //define your inventory

   private final Player player;
   //getter etc
}

public class InventoryData {
  private static Map<Player, InventoryBase> INVENTORIES = ...;
}

Something like this

I prefer doing it like this

Doesn’t matter in this case

[quaint mantle]

Yeah, don't store the whole player object in a map

[odd wedge]

Not really

[quaint mantle]

Just store the UUID instead of the whole player, you can get the player later on with the UUID anyway

Yep

[odd wedge]

It’s removed when they close the inventory

[quaint mantle]

How were we supposed to know that

It's still better to store the UUID instead of the Player object though

[odd wedge]

Sure

Anyways that how custom inventories should be stored instead of using inventoryholder

You might prefer them but it’s still not intended for that

You may use whatever you like

[odd wedge]

Because why would you store a reference when it doesn’t exist?

[quaint mantle]

"Anyways thats how you re-invent the wheel"

[quaint mantle]

You can still get an offline player object

[odd wedge]

I’m not reinventing anything

[quaint mantle]

with an UUID

[odd wedge]

But the inventory doesn’t exist anymore

[quaint mantle]

???

Just make a custom holder, It's that basic

[odd wedge]

But it’s still not intended for that

[quaint mantle]

It still works without any problems though ¯_(ツ)_/¯

[long zephyr]

may someone help me? :(

[quaint mantle]

Packets. Use packets.

I have seen that armor stand lag so many times now

Heck, I've even once made a gravity gun mod, and I had to use packets because of the lag that the normal teleport method has

[long zephyr]

i need an idea, i dont need a code, btw i just teleporting the armorstand to player location with an asynchTimer :c

[long zephyr]

i do it

[quaint mantle]

Hmm, yeah, maybe

Bukkit api isn't thread-safe IIRC

[long zephyr]

 new BukkitRunnable() {
            @Override
            public void run() {
                teleportArmorStand();
            }
        }.runTaskTimerAsynchronously(armorStandNMS.getPlugin(),0,1).getTaskId();

public void teleportArmorStand() {
        double y = maxY - teleportValue();
        Location entity_location = entity.getLocation();

        Location location = entity_location.add(0,y ,0);
        clientbound.teleport(location);
        teleportEntity(clientbound.getHandle());
    }

private void teleportEntity(Entity craft){
        ClientboundTeleportEntityPacket teleportEntityPacket = new ClientboundTeleportEntityPacket(craft);
        sendPacket(teleportEntityPacket,clientbound.getPlayer());
    }

clienctbound.teleport(location) =>

public void teleport(Location aum){

        try{

            armorStand.getClass().getMethod("teleport",Location.class).invoke(armorStand,aum);
        }catch (Exception e){
            e.printStackTrace();
        }

    }

[ivory sleet]

Well you have to manage it completely, that is on restart, as well as spoofing

Hence why UUID is almost always better

Though I suppose a WeakHashMap might be a fair choice

[tender shard]

wtf

reflection? for this? is this a joke? 😄

[long zephyr]

all versions :')

[tender shard]

all versions 1.16 and below*

wont work on 1.17+

[long zephyr]

its working xd

1.14 - 1.19.2

[tender shard]

what class is "armorStand"?

[ivory sleet]

Also MethodHandles

[tender shard]

NMS armorstand?

[long zephyr]

Object

[tender shard]

but what class is it actually?

[long zephyr]

CraftArmorStand

[tender shard]

CraftArmorStand? NMS Armor stand?

oh okay

yeah but

erm

why do you need a CRAFT ArmorStand to teleport it?

teleport is exposed in the Entity interface

[long zephyr]

bad named xD

[tender shard]

org.bukkit.entity.Entity#teleport

works in all versions

without reflection

[long zephyr]

mmmm

so, craftArmorStand.getHandle().getBukkitEntity().teleport(location) ?

[tender shard]

no

you dont need a CRAFTArmorStand

just use the bukkit armorstand directly

[long zephyr]

.-. i'm using NMS

[tender shard]

Entity myArmorStand = ...;
myArmorStand.teleport(...)

[tender shard]

no, you use craftbukkit code

org.bukkit.craftbukkit is not NMS

[long zephyr]

no xDD

[tender shard]

this is also a joke right?

[long zephyr]

org.bukkit.craftbukkit.VERSION.CraftArmorStand

[tender shard]

you have a CraftArmorStand, get the NMS entity with getHandle(), then get the BUkkit Entity again with getBUkkitEntity()?

[long zephyr]

lol

[tender shard]

Yeah you're trolling lol

sorry I didnt realize

just joined this chat a minute ago 😄

sometimes people actually do stuff like this so I wasnt sure lol

[long zephyr]

do you know about "org.bukkit.craftbukkit.v1_19_R1.entity.CraftArmorStand " ?

[tender shard]

ofc

OBC still contains the package names, yes

[long zephyr]

and "net.minecraft.world.entity.decoration.ArmorStand"

?

[tender shard]

sure

[long zephyr]

craftArmorStand.getHandle() its

xd

its not the org.bukkit.entity.Entity

[odd wedge]

Sure, comparing uuids might be more viable but that’s not what I was talking about

[tender shard]

yes, org.bukkit.craftbukkit.v1_19_R1.entity.CraftArmorStand#getHandle returns net.minecraft.world.entity.decoration.ArmorStand. But org.bukkit.craftbukkit.v1_19_R1.entity.CraftArmorStand implements org.bukkit.entity.Entity and that exposes the teleport method, so you can treat any CraftArmorStand like a normal bukkit entity

[ivory sleet]

Yes, but I was just trying to imply the additional complexity Player as K type will provide

[long zephyr]

now i understand you

[odd wedge]

I mean it doesn’t really

[tender shard]

both works fine

[ivory sleet]

It does

[tender shard]

no need to use CraftArmorStand when you only use interface methods

[long zephyr]

btw i'm doing that here armorStand.getClass().getMethod("teleport",Location.class).invoke(armorStand,aum);

[ivory sleet]

Because Player objects are much more fragile due to the state they need to encapsulate

[tender shard]

yes, that's totally unneeded

you can just do armorStand.teleport(aum)

[long zephyr]

armorStand is an Object

:c

private Object armorStand;

[tender shard]

then cast it to org.bukkit.entity.Entity

[eternal oxide]

Stop instancing it as an Object then

[tender shard]

if you want to go "for all versions", then using org.bukkit.craftbukkit... is the opposite of what you want lol

[long zephyr]

but org.bukkit.entity.Entity ? or net.minecraft.world.entity.Entity;

?

[tender shard]

bukkit

why do you have a CraftArmorStand in the first place?

[long zephyr]

so net.minecraft.world.entity.decoration.ArmorStand. But org.bukkit.craftbukkit.v1_19_R1.entity.CraftArmorStand into org.bukkit.entity.Entity ?

[tender shard]

the teleport method on org.bukkit.entity.Entity has been around since FOREVER

[tender shard]

I will try to explain:

EVERY org.bukkit.craftbukkit.v1_19_R1.entity.CraftArmorStand is also a org.bukkit.entity..ArmorStand

[long zephyr]

i didn't know it was possible

[tender shard]

I still think you're trolling, or maybe you watched a tutorial on youtube that's trolling

[eternal oxide]

too many tutorials and code suggestion from the IDE

[long zephyr]

noup, just think was different lol

[tender shard]

?paste your whole class pls

[undone axle]

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

[tender shard]

You should always use the interface classes

they will work in all versions

no need for reflections and stuff

and an armorstand should (almost) never be stored as plain Object

but simply as bukkit (not craftbukkit) Entity or as bukkit ArmorStand

everything else is just making stuff overly complicated and/or slower

[long zephyr]

but then i should do for all versions to get compile well

[tender shard]

holy shit

I made a plugin for myself that has a player death event listener. It has a config.yml file but i want to add a "❤️" emoji to show how much health the killer had left. But the plugin's default encoding cannot show that and shows some other random thing. How can i fix this?

[eternal oxide]

be sure you created/saved the config.yml with utf8 encoding

[kindred valley]

Everyone trolling you alex

This is some code for a mob I'm working on but line 70 and 77 are just not doing anything. The variable sh is fine when I print it but it doesn't change the nametag.

[eternal oxide]

Early returns are best practice, however they are odd to get your head around. You are instinctively thinking "under what conditions SHOULD my code run" not "when should my code NOT run".

[tardy delta]

-Infinity 🤡

me trying to get rid of a field and fucking up other stuff

[eternal oxide]

yeah math hard there 🙂

[glossy venture]

what does the divisor do

[tardy delta]

?

[glossy venture]

why dont u just store the value

[tardy delta]

too many if else statements to parse a double by iterating over the chars

so made a dedicated class

with some validation too

[glossy venture]

oh alr

so its for parsing?

[tardy delta]

kinda

[glossy venture]

u could do smth like

StringReader reader = new StringReader(source, 0);
String dstr = reader.collect(/* condition */ c -> isDigit(c) || c == '.', /* skip */ c -> c == '_');
double d = Double.parseDouble(dstr);

does anyone know how to like give something if a player kills someone else

cuz apparently playerDeathEvent doesn't work

"doesn't work"

code?

[limber owl]

how do I add a server resourcepack to custom gui

[tardy delta]

items with a custom model data

meh had to change it

[iron glade]

This channel now called Development showcase

[echo basalt]

we do that sometimes

[iron glade]

What's that math project thing about ur working on? @tardy delta

[limber owl]

can I create custom gui, with custom model data and custom slots? it should look like your own inventory, but of another player

[tardy delta]

https://github.com/FourteenBrush/MathExpressionParser

havent pushed a while tho

[limber owl]

.

I don't know, I know it should look something like this, but with cobblestone background and on the right shield and sword I think? (can I send pic in DMS?)

[quaint mantle]

u can send here

[limber owl]

I can't, I'm not verified because no staff wants to unverify my account on spigot

sent

[shadow night]

what packet is sent to the server when the client gets info about it and how do I modify the info it sends from the plugin?

[limber owl]

it should look like this

yea, knew it would be something like this

[agile anvil]

You can do it using resource pack

but this one is tricky

[limber owl]

wait, can't I just retexture the chest gui?

[tardy delta]

yes

[agile anvil]

those are just hidden slots

[agile anvil]

Is it from Origin Realm?

[eternal night]

mcc

[quaint mantle]

making these with mods are possible

[shadow night]

uhh?

[limber owl]

I think if I use normal chest, retexture it using resourcepack, an put the head as head item, and on the right the shield and on leaft armor

[agile anvil]

With resource pack too

[agile anvil]

Info about about ?

[shadow night]

it refers to server

[agile anvil]

So what info ?

The server sends a lot of info

[shadow night]

motd, player list, player count... info you can see on the server in the server list

[agile anvil]

https://wiki.vg/Server_List_Ping

Yes you can change it, use a packet wrapper like ProtocolLIB and change those fields

[shadow night]

and how do I change it without a wrapper?

[limber owl]

so?

[agile anvil]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/event/server/ServerListPingEvent.html

[agile anvil]

Yes you can do it

But you'll need to do some InventoryClickEvent listening to avoid them using some slots

[limber owl]

thats no problem

[shadow night]

hmm and is there a way to add extra info for non-clients?

[eternal night]

why would you use the ping format for non minecraft clients 🤔

[shadow night]

a discord bot for example?

[eternal night]

yea but why not just expose a proper API for that from the server

instead of hijacking the minecraft port

[shadow night]

idk I thought I'm too lazy to make something by myself so I'll just modify the existing

[agile anvil]

Making that will break the minecraft protocol

[shadow night]

uh why?

[agile anvil]

As you read, it's strict

The client reads specific fields

Adding a field or removing one will consider the server as broken

[shadow night]

break-your-server plugin

[long zephyr]

hello ^^
Does anyone know how to avoid the shaking of the
ArmorStand when being teleported?

new BukkitRunnable() {
            @Override
            public void run() {
                teleportArmorStand();
            }
        }.runTaskTimerAsynchronously(plugin,0,1).getTaskId();

public void teleportArmorStand() {
        double y = maxY - teleportValue();
        Location location = entity.getLocation().add(0,y ,0);
        teleport(location);
        teleportEntity(((CraftArmorStand)armorStand).getHandle());
    }

private void teleportEntity(Entity handle){
        ClientboundTeleportEntityPacket teleportEntityPacket = new ClientboundTeleportEntityPacket(handle);
        sendPacket(teleportEntityPacket,player);
    }
public void teleport(Location aum){
        armorStand.teleport(aum);
    }

[agile anvil]

If you're still lazy which is great but not too great, just encode some message using chatcolors in the motd would do the trick

[quaint mantle]

finally free from chat reporting

just don't have servers

[agile anvil]

Can't you make the armorstand sitting on the player ?

[eternal oxide]

why are you teleporting AND sending a teleport packet?

[long zephyr]

nameTag get bugged into the player :(

[long zephyr]

NMS

[eternal oxide]

Doesn;t matter. you don;t need the packets at all

you are calling Bukkits teleport, you don;t need any NMS

[long zephyr]

yep if i dont send the packet the armorStand dont change the position in the client

:(

[eternal oxide]

yes it will

[long zephyr]

i did it and it doesn't :C

[eternal oxide]

It will unless you did something wrong. It can;t fail to update the client.

I will test

[molten hearth]

uh does anyone have experience using git, say I changed 5 files from a repo from my knowledge I should create a pull request and not just commit them right?

[quaint mantle]

uhm do I have to wait for his problem to be solved to post my problem?

[molten hearth]

but dont I need to make a whole branch on their repo to create a pull request? 🤔

[long zephyr]

ArmorStand entity_armorstand =  new ArmorStand(EntityType.ARMOR_STAND, (Level) worldServer);
            armorStand = (org.bukkit.entity.ArmorStand) entity_armorstand.getBukkitEntity();

//so i send this packets
private void packetsCraftItem(Entity craft, int id) {
        ClientboundAddEntityPacket clientboundAddEntityPacket = new ClientboundAddEntityPacket(craft);

        packetMetaData(craft,id);
        sendPacket(clientboundAddEntityPacket);


    }

[agile anvil]

If it's not your repo, you have to fork the repository and commit push to your fork. All the changes made from a branch can be converted into a PR to the original repo (so it's recommended to create a branch in your fork per PR)

[agile anvil]

Do you want the armorstand to be visible only by one player ?

[long zephyr]

yep

[quaint mantle]

public class HandlerOfEvents implements Listener {

    @EventHandler
    public void death(PlayerDeathEvent event) {
        if(event.getEntity().getLastDamageCause().getCause().toString().equals("end_crystal")) {
            event.getEntity().sendMessage(event.getEntity().getKiller() + " Killed you with an end crystal");
        }
    }

}

I'm trying to detect whenever you die from an end crystal and get whoever killed them

[molten hearth]

oh thanks ill give that a try

is there any way to do that after I just git cloned the repo and edited it

[agile anvil]

You should not create a Bukkit Entity then. Use directly a NMS ArmorStand

[agile anvil]

And ?

[quaint mantle]

idk

i tried other things would nothing works

[agile anvil]

I recommend finding tutorials online. There are plenty of them that provide step by step solutions

[quaint mantle]

i know

i accidently forgot to save code from last night

[agile anvil]

First, debug the death cause and die from an ender crystal

Then when you find the cause name

[quaint mantle]

k

i'll do that

k

[agile anvil]

What context ?

[quaint mantle]

but how do I get the killer?

[molten hearth]

eh nothing is easy with git 😂

[agile anvil]

You'll have to destroy few repositories before starting to understand x)

[quaint mantle]

^

should I do this?

@EventHandler
    public void death(PlayerDeathEvent event) {
        event.getEntity().sendMessage(event.getEntity().getPlayer().getKiller().toString() + " & " + event.getEntity().getLastDamageCause().getCause());
    }

[tardy delta]

smh

[agile anvil]

getKiller returns a Player and can be null

[long zephyr]

now i'm working directly with NMS but still teleporting with dealy :(

[quaint mantle]

brb

[agile anvil]

there is no way to improve it, except sitting the entity

[quaint mantle]

back

[agile anvil]

or maybe teleporting the armorstand on the playermoveevent but I'm not sure about that

[long zephyr]

but name tag display bad, also if the player go into the water the armorstand is disassembled

[quaint mantle]

then how do I get the killer

[cobalt tinsel]

hi

which is the number for the healing potion?

[eternal night]

number ?

[cobalt tinsel]

yeah like

[quaint mantle]

i think they mean the id

[cobalt tinsel]

to make the Material.POTION

a healing one

[eternal night]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/inventory/meta/PotionMeta.html#setBasePotionData(org.bukkit.potion.PotionData)

you'd use this method

[cobalt tinsel]

api 1.8 😅

[eternal night]

bruh

[swift dew]

is there any way to use a plugin coded in the deobfuscated spigot(nms)?

[cobalt tinsel]

yeahhhhhh :p

[eternal oxide]

?paste

[undone axle]

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

[eternal night]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/inventory/meta/PotionMeta.html#setMainEffect(org.bukkit.potion.PotionEffectType)

I presume

[eternal oxide]

@long zephyr The stand teleports and moves just fine using only Bukkit teleport. It will only update location 20 times a second as thats the max tick rate. https://paste.md-5.net/ofejiwozod.java

[cobalt tinsel]

pot.setMainEffect(PotionEffectType.HEAL);

[heavy swan]

What version of spigot do I need for my plugin to work for all versions of minecraft?

[eternal oxide]

You build against the oldest version of Spigot you want your plugin to work on

and set the API version in the plugin.yml if you are going back a long way so it can understand legacy Materials

[heavy swan]

I want the plugin to work from 1.8 to 1.18 which api should I use more recommended for a 1.8 server?

[eternal oxide]

if you want it to work on 1.8 then 1.8

[tardy delta]

ah a switch doesnt work on a null value :/

[eternal oxide]

not at all or will it fall through to default?

[eternal oxide]

java 18 supports it

[eternal night]

by not using inheritance

[tardy delta]

on java 17 smh

[eternal night]

well that makes no sense xD

an object is an object

[onyx fjord]

can i do something more with actionbar than just sending it without any params?

(i mean stuff like title that has fade times)

[eternal night]

Well what you want is composition

if you want to pass Test2 to Test as a form of "parent"

[eternal oxide]

or implement cloneable

[quiet ice]

no

Unless you mean something really differently, the sematics of such code cannot be replicated at all

Yeah, then make super have a constructor that takes in an instance of itself to copy the values

how would it not work?

[tardy delta]

public SuperClass(SuperClass other) {
  this.smth = other.smth;
  // etc
}```

ez

[quiet ice]

If you are a fan of reflections you could use that, but I'd not use that

And I am sure that lombok has an annotation for that, but similarly I'd not do that

[safe hatch]

how can I display text above players head. Like how much hearts this player has or something like that

[quiet ice]

its not about liking but also performance along other things

[quiet ice]

I assume through scoreboards but I never tested that

not slow, just slower

[long zephyr]

:o

ty i'll check what you did, ty <3

[wet breach]

use invisible entities 🙂

[quaint mantle]

Does TextComponent exist in 1.8.8 spigot?
Should I import it through net.md_5.bungee.api.chat.TextComponent or java.awt.TextComponent?

ohh wait i can't show action bars in 1.8?

[quiet ice]

no it does not

java.awt.TextComponent is in the awt package - which like the JFX and swing packages is strictly forbidden to use in spigot

While you can use it, it is likely that you shouldn't

[untold monolith]

good, by any chance can you change the name of the spigot website?
if so, how would it be?

[quaint mantle]

Hmm. So, how do I show action bars in 1.8.8?

[tardy delta]

meh i thought you could do Node::token but no thats a method reference

ugly

[iron glade]

not really

[tall dragon]

with reflection

[tardy delta]

good ol' reflection

[torpid sapphire]

does anyone have a clue why Inventory#setItem doesnt remove the item from a slot? java if (event.getClickedInventory() instanceof AnvilInventory inv) { ItemStack clickedItem = event.getCurrentItem(); if (clickedItem != null && clickedItem.getType() == Material.DIAMOND && event.getSlot() == 2) { event.getView().setCursor(clickedItem); inv.setItem(2, null); } }

[untold monolith]

Or am I supposed to donate for the name change? If so, where did you donate and to whom did you inform?

[low condor]

Hi, im having trouble with my teams/scoreboard
can anyone help

https://pastebin.com/pDsTRDjC

[tall dragon]

yea i believe for 10 bucks you will get permission to change your name. its on the homepage of spigot

donations are processed manually, might take a few days

[iron glade]

set it to air

[torpid sapphire]

tried that

didnt work either

[iron glade]

that's weird

[torpid sapphire]

i mean its the output slot of an anvil i dont think it really likes that

[iron glade]

use #remove

maybe this works

[iron glade]

Ahh anvils can be tricky

[torpid sapphire]

so remove(clickedItem)

[iron glade]

ye

[torpid sapphire]

same thing

doesnt wanna remove it

[tall dragon]

idk what ur tryna do but i think you need to use AnvilPrepareEvent

and use #setResult

[torpid sapphire]

cant

[iron glade]

Might have to remove it every tick

[tall dragon]

well wat u tryna do

[iron glade]

Or you can't, idk

[torpid sapphire]

im adding a second item to the output slot after you take the first one out

[iron glade]

Anvils are weird

[torpid sapphire]

its janky ik but i need it to work

[tall dragon]

you might as well create a custom anvil then..

would work much cleaner

[iron glade]

I think u have to also replace the input slot then

[torpid sapphire]

thats what i thought too but how am i supposed to do the text input

[iron glade]

could use chat

[torpid sapphire]

or make a completely custom anvil block and use that for repairs, and the default one for combining and renaming

cause i just need this for repairs

[grizzled owl]

can i implement vault economy without downloading external plugins like essentials?

[quaint mantle]

yes

[humble tulip]

Yes

It doesn't update

[grizzled owl]

i added vault api and it still throws Disabled due to no Vault dependency found! (i have depend vault in plugin yml and vault installed), how can i fix that

[humble tulip]

Objects aren't stored in the hashmap

Just a reference to it

It does
