upper hazel
#

listen, if i read the entire backkit documentation in full, will i be able to write good plugins?

flint coyote
#

No

#

There's more to it

#

Knowing every engine and car type won't make you a good driver

upper hazel
#

I have 2 years of practice if that's what you mean

remote swallow
#

no

#

hes saying by knowing the entire bukkit api wont make you a better plugin developer

#

time making plugins and using the features and learning them as you need will

lilac dagger
#

which one is more readable?

image.png
#

to me they both look the same

flint coyote
#

ticks and 20 is pretty known, I'd say second

upper hazel
#

hell if I read the documentation I would make a plugin for spawning structures 2 times faster

mortal hare
#

first one if i was new to bukkit

flint coyote
#

faster != better

sterile breach
#

i think

flint coyote
#

Usually you learn a lot while coding. It's not like I got all my knowledge about best practices by constantly reading documentation and guides

upper hazel
#

but if there is practice, then it will definitely become better because you already know 50 percent how everything works

#

I spent a week on the plugin due to ignorance of damn 1 event like so

sterile breach
#

the most important thing for me is to acquire a certain programming logic, which I think you develop by coding.

upper hazel
#

But how do you like the idea of ​​​​taking 1st class at the docks and using it for practice, and so every time until the end?

#

teach class - practice - teach class - practice

sterile breach
#

yes, but I'm still a beginner in programming. I'm saying what I think I understand, but maybe that's not it.

tender shard
#

Nobody reads the docs, they are not a book lol

flint coyote
#

Also they are huge. If you think something you currently need could be part of the api, you google and find the docs (or not)

#

If still unsure you can always ask here

sterile breach
#

yes, we often understand better when we find forums with people who have already had our questions

flint coyote
#

I mean most of the time we even answer questions that could be answered if the person typed their question into google.

sterile breach
#

yeah

is the same

#

i have a quesition with serverinfo.senddata. I've been looking for 3 days but I don't understand. serverinfo.senddata() sends a message plugin to all players on the server in question? or a random player on the server?

sullen marlin
#

random

#

can easily check the source to confirm

hushed spindle
#

im trying to use Class#getResourceAsStream but i seem to be unable to actually get to a resource in my jar file. I use this method on my main class which is located in Plugin/src/main/me.athlaeos.plugin. If I want to get a file in my resources folder which is in Plugin/src/main/resources. When I use getResourceAsStream I understand it attempts to find a file within the module the class is located in, and this would be Plugin I understand right? so the path to enter to go to that file in resources should be src/main/resources?

#

or would the modile in this case be me.athlaeos.plugin in which case i need to go up a folder first

remote swallow
#

getResourceAsStream("plugin.yml") for src/main/resources/plugin.yml

hushed spindle
#

yeah idk then it keeps saying it cant find the file

#

sec lemme try again

remote swallow
#

check the spelling

#

and run a clean build

sterile breach
hushed spindle
#

what do you mean with clean build? like remove targets?

image.png image.png
remote swallow
#

mvn clean package

#

gradlew clean build

hushed spindle
#

still nothing

#

ill try something else

tender shard
#

getResourceAsStream("/skills/smithing.yml")

hushed spindle
#

god damn it

#

thank you alex ily

#

or jeff

remote swallow
#

any reason for not using JavaPlugin#getResource also

sullen marlin
tender shard

twilit creek
#

Is it possible to send a Packet to the player that only plays the effect of an explosion but not the sound? (1.20)

tender shard
#

isn't the effect just a particle?

twilit creek
tender shard
#

there's spawnParticles for that

hushed spindle
#

Player#spawnParticle will display particles to only that player yeah

#

or do you want it to do damage and do knockback also

#

so just an explosion minus the sound

twilit creek
#

Oh i must think more simple. xD I try it.

kindred sentinel
#

how to clear player's server resourcepack?

sterile breach
tender shard
#

the NMS Explosion class has a method finalizeExplosion(boolean) that, when the boolean is false, does not play any sound

#

but bukkit doesn't seem to have a method for that

#

nvm I am stupid

#

what the heck is Level.isClientSide

image.png
twilit creek
echo basalt
#

when you're running a singleplayer world it creates an internal server

#

and sets that to true for some special special checks

tender shard
#

just spawn particles with either EXPLOSION_HUGE or EXPLOSION_LARGE or EXPLOSION_NORMAL.

tender shard
tender shard
echo basalt
#

I think there's some client-sided preditions that the client does

#

Like this for shears

tender shard
#

funny

#

why doesn't it just let the builtin server do that job lol

echo basalt
#

weird optimizations or it'd look clunky with predictions

#

There's also a class for debugging that's just left empty on the server

tender shard
#

yeah well but if the client "predicts" the explosion on a normal server, why not just also let the client "predict" it for the builtin server

echo basalt
#

network latency perhaps?

twilit creek
tender shard
#

vanilla uses HUGE for explosions greater than 2.0, otherwise it uses LARGE btw

echo basalt
twilit creek
tender shard
#

or when an entity steps on turtle eggs lol

twilit creek
tender shard
#

that's from PathfinderGoalRemoveBLock

image.png
#

idk where the "eggs" part comes from, I only read that in the craftbukkit comment

twilit creek
tender shard
#

found it - the zombie is the only entity that uses this goal, and they are having TURTLE_EGG in the constructor for that pathfinder goal

image.png
#

so it seems like zombies walk to turtle eggs on purpose and destroy them lol

#

i didnt know that

slender elbow
#

yeah they attract zombies

twilit creek
slender elbow
#

or, well, the other way around I guess lol

tender shard
#

what do zombies have against turtles

twilit creek
#

Ah i see, but it is a very low chance that this effect appears. I think only by the last egg.

remote swallow
twilit creek
#

They are both green haha

tender shard
#

true

twilit creek
#

This effect seams that they have a 10% chance to spawn this particles.

tender shard
#

Is it fine to name a main class Main (standalone application) lol

twilit creek
#

But they only hate the eggs not the turtle self.

slender elbow
#

sure

lilac dagger
#

i'm looking for a public repository to host my apis, which one is the best?

tender shard
slender elbow

how is a bone a block dispaly

im trying to make procedural animations

and the block displays will be legs

remote swallow

ah

i getit

tender shard
#

so your math is weird

near mason
#

oof

#

i hate math 😭

unreal quartz
#

Probably a divide by zero somewhere

near mason

the only math is here```java

public Vector direction(){
    return end.subtract(start);

#

are you not extending JavaPlugin?

unreal quartz
#

I heard Fleet's diagnostic is a bit scuffed

tender shard
#

fleet was completely useless garbage when I last tried it, but that was months ago

unreal quartz
#

Such as showing errors where there shouldn't be

orchid trout
#

it compiles just fine lol

round finch
#

are you using maven or just a jar?

near mason
#

than IJ cant decompile the dependency

How to hide or remove command like /plugin-name:command
And leave only /command?

orchid trout
#

ill probably test out vs

near mason
#

did u reload pom?

tender shard
orchid trout
#

the ui is a lot like eclipse

round finch
#

hehe use notepad++

#

wait are we joking?

tender shard
kindred sentinel
#

Oh ok thanks

orchid trout
#

the player will still be able to execute them right?

#

you would have to listen for commands if you want to disable that as well

kindred sentinel
#

I just want to disable tab completion of commands like /pluginname:command

orchid trout
#

ok

tender shard
orchid trout
#

ahhh time to go back to eclipse

#

and burn my eyes out

kindred sentinel
#

What's wrong with intelij idea?

tender shard
#

try IntelliJ without the minecraft development plugin

orchid trout
#

i like having multiple projects on in the same window and intellij bsods me sometimes

#

i uninstalled it

#

pretty sure i was still crashing

tender shard
#

huh but IJ can do that

remote swallow
#

I would love fle eclipses file system in intellij

orchid trout
#

idk im just tired of ij a bit

tender shard
#

but weridly only when it's on fullscreen

kindred sentinel
#

When i was trying to do something with Eclipse it was too uncomfortable..

orchid trout
#

eclipse's ui is ass

tender shard
#

yeah but IJ's new UI is also shit

kindred sentinel
#

But we don't have any replacement except intelij idea & eclipse

orchid trout
#

ij is a grey spot in my mind so i cant comment

i wonder right now, does java prehash records so that hashcode() would return the same hash code internally without having it to compute everytime

you went from seeing 70 classes to 60 or something right?

i prefer new ui since you could easily more focus on the code

near mason
#

new ui better

tender shard
mortal hare
orchid trout
#

i dont know what any of those buttons do

mortal hare
#

that were provided there

#

i prefer context menus, at least they tell me what they briefly do

tender shard
mortal hare
#

not all of them

tender shard
#

all this is useless. I mean, why don't they at least get rid of this bar completely then

image.png
#

the editor window could at least be bigger then

#

now it just displays a completely empty thing

mortal hare
#

well that's correct

#

maybe they will change it

tender shard
#

the git buttons are also all gone

#

push, pull, ...

mortal hare
#

version control button exists

#

where you access everything

tender shard
#

where is that?

mortal hare
tender shard
#

there is neither a push nor a pull button in that menu

image.png
#

they have moved it into the menu at the top so you now need an extra click. and it's also the only useful button in that whole unused bar at the top

image.png
mortal hare
tender shard
#

why are you not using maven or gradle?

tender shard
orchid trout
#

i hate eclipse mostly because i just click a random button and my project explorer, problems or something else just disappears and i have to spend a few minutes clicking random buttons for it to reappear

unreal quartz
tender shard
#

you should use maven, otherwise nobody can clone your project without manually setting up a thousand things

tender shard
orchid trout
#

what does jeff-media do

unreal quartz
#

oh

mortal hare
#

yea you should use either maven or gradle, since those can store your build setup for the next contributor or cloner

tender shard

#

trust me its better than what i've saw here before 😄

orchid trout

i will apply to work at jeff-media when i turn 18

tender shard

we're already full

will you still be full in 3 years?

yeah well but I didnt do the website

mortal hare
tender shard
#

the blog uses a bought theme

orchid trout
#

those are fine

mortal hare
#

on my monitor they're like flashbangs

#

at night

tender shard
#

idk if the main website theme is also bought or whether one of the other dudes made it

mortal hare
#

it just not comfortable to focus

tender shard
#

all I remember is that the blog theme costed like 100€

mortal hare
#

grayish borders would be better imo

tender shard
#

if I could decide, the blog wouldn't even use dark mode

#

visit the blog again now

#

this is how I'd make it look

#

i never understood why everyone is so obsessed with dark mode lol

if your brightness is at 100 and you hate the sun then dark mode is fantastic

pseudo hazel

doesnt really sound like something you can do easily if at all

tender shard
#

the player info packet includes the skin

#

it won't work for yourself, ofc

#

and you'll need signed texture data

#

so yeah ClientboundPlayerInfoPacket is what you'll need I guess

Good morning chat

is playerconnectionvar.a() the correct syntax for sending packets

the correct way is Connection#send(Packet<?>)

hi

#

any idea why when I serialize a item stack to byte array and then deserialized it back to a itemstack it changes the lore?

orchid trout
orchid trout
#

code

hardy shell
#

sec

#

byte[] serialized = player.getInventory().getItemInMainHand().serializeAsBytes();

#

just adds it sqlite db for later use

orchid trout
#

uh

#

i serialize it differently

young knoll
#

I think that’s a paper method

#

👀

orchid trout
#

uh oh

hardy shell
#

yea

orchid trout

anyways

how do you do it?

how do I get a prepared statement from a connection?

does anyone know how i would create an effect similar to how the treecapitator works on hypixel skyblock: where if i mine a block it will iterate over the connected blocks of the same type and break them

try (PreparedStatement preparedStatement = connection.prepareStatement("USE Players; SELECT Lang FROM 'PlayerData' WHERE UUID = '?';")) {

use java 17 first off

its just a nickpick, but you should be using java 17 with later minecraft versions

also you sohuld beable to just reload your project and it should work

Is there an event that triggers when a player loads in a chunk already loaded? What I mean is, for example, if player B was in a loaded chunk, and player A just got the chunk in their render distance. Is there a way to efficiently detect when a player gets a new chunk sent to the client?

the listener itself

#

the startlistener, stoplistener, and the packetlistener is the important stuff

#

sorry for text wall

wary topaz
opal carbon
#

it means that multiple jars have a manifest.mf

#

and its only gonna use one

#

for spigot plugins it basically means nothing

wary topaz
#

how can I remove the warning though? its annoying

opal carbon
#

well the manifest.mf

#

means nothing

#

the other stuff could possibly be more concerning

opaque scarab
opal carbon
#

you should relocate your dependencies

#

so that they dont overlap

opal carbon
#

not sure if that helps you but overall again the main thing you really need to understand is the ChannelDuplexHandler and the start/stop listener code

#

i will say my handler only uses "write" so only when a packet is sent does it detect it

#

for incoming packets use the "channelRead" method

#

similar overall concept in that case where you can use instanceof to differenciate and act on it

#

the reason i call super.write before returning in all the spots where i return is if you return WITHOUT calling that it wont actually write the packet

#

same thing for super.channelRead if you are reading packets, the server will basically not know the packets exist if you return without calling super.channelRead

buildtools puts a jar in a maven repository

i think it's the right repository

#

thenAccept() just won't run if an exception is thrown and nothing will be shown to console. I suggest using whenComplete() if you want to handle the error

Message.getMessage(player.getUniqueId()).whenComplete((language, e) -> {
    if (e != null) {

How can I convert a chunk to a LevelChunk?

whether they are exposed or not

Chunk -> CraftChunk which has a handle for LevelChunk

usually the handle is in a #getHandle method

there are some weird cases where some bukkit classes don't always have to be their Craft equivalent, this is common with ItemStacks so just be aware

ChunkStatus.BIOMES, ChunkStatus.STRUCTURES

PacketEvents is real nice

Can I use ChannelDuplexHandler?

Just use some sort of wrapper

you will save yourself so much time

#

Wdym

like use protocollib or packet events if u are trying to ujse packets

#

trying to set the player's skin with playerprofiles. when i execute this, the first time i got. there are no errors but i can visibily see on tab i was removed, but i don't get added back.

ServerPlayer plyr = ((CraftPlayer)player).getHandle();

plyr.connection.send(new ClientboundPlayerInfoRemovePacket(List.of(((CraftPlayer)player).getUniqueId())));
profile.getTextures().setSkin(new URL("http://textures.minecraft.net/texture/b3fbd454b599df593f57101bfca34e67d292a8861213d2202bb575da7fd091ac"));
plyr.connection.send(new ClientboundPlayerInfoUpdatePacket(ClientboundPlayerInfoUpdatePacket.Action.ADD_PLAYER, plyr));```
opaque scarab
#

This is a really weird way, but what if I get the X and Y of the chunk in the packet to be sent. Then I get the chunk from the world, provided the coordinates, and copy it, then edit the contents. Afterwards, I create a new packet with the updated chunk. Does this seem like a good way?

i have to send both of the packets to all players?

river oracle
#

anything can be a command sender right?

#

pretty sure that's how entities work internally

quaint mantle
eternal oxide
#

yes they can

#

you have to send a respawn packet to the player for their own skin

#

you have to do a few things to perform a skin change

#

things like inventory and op break

how do i work hibernate with hikaricp ?

I store a map of the Players UUID and then a map of Location Block

is Bukkit.getworld case sensitive?

eternal oxide

all worlds are indexed to lowercase

orchid trout

why

quaint mantle

i put "World" inside bukkit.getworld not "world" is that my problem

eternal oxide
#

probably not

drowsy helm
eternal oxide

it shoudl lower case for searching

Or you forgot to compile

orchid trout
#

i didnt

#

i saved

clean then build again

Decompile it and see what the code looks like

how long is 180000l?

I assume that's in ticks. So: 180_000 ticks / 20 = 9_000 seconds

what api can be used for mysql to make it convenient? Is there a popular optimized api?

eternal night
#

jooq is pretty nice

upper hazel
#

i can use this in bukkit api?

#

i mean not will crush server?

placid moss
#

database access shouldnt be on server thread anyways

#

so it shouldnt affect the server speed that much

upper hazel
#

pool connection

eternal night
#

well yea

#

hikari is a very common sql pooling lib

upper hazel
#

jood end hikari hah

#

it just infuriates me to write requests on a bare JBDC

opal carbon
#

damn

#

what did jbdc do to you

upper hazel
#

need to spend a lot of time

opal carbon
#

never had issues with jdbc personally but to each their own ig

upper hazel
#

the problem is not in the JBDC itself, but in the fact that it takes a long time to write requests and is cumbersome

#

cumbersome

#

I have 1 database class takes an hour while writing code

opal carbon
#

oh well could just be that im not exactly a sql magician anyways so havent done any crazy fancy requests

upper hazel
#

all this optimization and so on

#

so jood or hakari is better

eternal night
#

two different things

#

one is a connection pool

opal carbon
#

(hikari)

upper hazel
#

pool?

eternal night
#

hikari is responsible for pooling SQL connections

#

so you don't open and close them all the time

#

but properly reuse them

#

JOOQ is a helper utility for writing the SQL

This code is used for checking a pickaxe and giving it the correct EXP so like a leveling system but showing on the bar for checking i used the PlayerLevelChangeEvent, the problem comes when I'm switching when i switch from something i have my EXP (40LVL) but in the pickaxe, i have 2 levels so my plugin gives the reward and everything to the other user

if you need to modify the creeper use the consumer method

yup
Creeper creeper = world.spawn(location, Creeper.class, creeper -> {
creeper.doStuffHere();
});

it'll set before it is spawned

i'm using it to cancel the snowball particles if it hits the wall

can i check there if the snowball hit an entity and cancel it appropriately?

there may not inventory, you may need to use player.getEquipment

#

iam on old version

hybrid turret
#

Isn't

if (!(sender instanceof Player player)) {
  return;
}
UUID uuid = player.getUniqueId();

supposed to be working? Someone said it would work but my IDE is screaming at me that I can't access player since it's not in the if-block.

and said this
player.getInventory().getArmorContents()

it's about accessing player outside of the if block

noobdogs code was just wrong

what are u trying ?

long story.. wait let me get my original code lmao

quaint mantle
#

aight

hybrid turret
#

basically my code was one big arrow

#

and that was a problem

#

wait i can just send a different command bc i gotta refactor all of them anyway

quaint mantle
#

can you briefly explain, what is your problem?

hybrid turret
hybrid turret
#

a bit hard to explain bc i myself still have to wrap my head around that bc it's new structure for me

hybrid turret

#

in my opinion u need do this code with early returns

#

your code will be more readable

hybrid turret
#

yes, that's what i'm trying to achieve

#

i know

#

ah

#

aight

#

i will give example for u

example for permission if

if (!sender instanceof Player) return;
if (!p.hasPermission("serversystem.activate.norain")) {

    return;
}
if (args.length == 0) {
    sout("usage message")
    return;
}

#

the instanceof needs double brackets

#

yeah i get that. the problem is now: there's different stuff happening depending on if a player uses the command and if a console does that

      GlobalBooleanUtils.setDeathEnabled(false);
      sender.sendMessage(ServerSystem.getPluginPrefix() + "You successfully §aactivated §3noDeath§7.");
      for (Player onlinePlayer : Bukkit.getOnlinePlayers()) {
        if (onlinePlayer != sender) {
          onlinePlayer.sendMessage(ServerSystem.getPluginPrefix() + ((sender instanceof Player) ? ("§b" + sender.getName()) : "An §4administrator") + " §7has §aactivated §3noDeath§7.");
        }
      }
    } else {

        }
      }
    }
  }

for the bottom method

#

wait this can be shortened even more

i checked that event

#

but it doesn't say anything there

#

oh, no clue for that

hybrid turret
#
