Memory is cheap \s

[brave sparrow]

Storage is cheap

Memory is pricey

But getting cheaper

[brave sparrow]

That’s VSCode, you have to install a bunch of extra stuff if you want a “create project” type thing

[quiet ice]

Honestly, I always found vscode more like a generic text editor than anything usefull for development

[grim ice]

how do i do that then

[brave sparrow]

That’s basically what it is

[quiet ice]

At that point you might as well use vim or emacs

[brave sparrow]

It’s a slightly more powerful text editor more than an IDE

Realistically

[buoyant viper]

pretty much

[native bluff]

Anyone knows if there's a way to color the players names above head with hex colors?
Team.setColor doesn't support Hex unfortunately

I even tried looking up some packets but nothing seems to do the trick

[sacred mountain]

is anyone here good at art and can make me a pfp

i made mine in ms paint

[tall crystal]

who can help me with a plugin

[sacred mountain]

wrong channel sorry lol

[brave sparrow]

Are you sure the game supports it?

[grim ice]

so uh what do i do

[brave sparrow]

Google it

[sacred mountain]

just create a hologram

with rgb

[grim ice]

didnt work out

[sacred mountain]

above the player

[native bluff]

Nop. Couldn't really find any source

[native bluff]

Yeah, that's a bad idea .-.

[quiet ice]

I personally use Geany for C dev, but that is another pretty generic text editor

[sacred mountain]

welp then im not sure

[brave sparrow]

You googled visual studio, not vs code. You need to Google for your setup

[grim ice]

no

[sacred mountain]

i dont know if you can do it in player names/tags

[grim ice]

i was googling vscode

i didnt know visual studio even existed

[brave sparrow]

Ok one sec I’ll look for you

[quiet ice]

Do you have the C++ extension installed?

[grim ice]

yes

C/C++ thing?

[quiet ice]

Well, then you are on-par with my knowledge

[ivory sleet]

iirc yes

[sacred mountain]

listen to the orange guy

[grim ice]

thats why i hate anything other than jetbrains

[ivory sleet]

like you can probably pass an int

[grim ice]

too confusing

but CLion is moni

and i dont have that student shit they want

[tardy delta]

orange guy :kekw:

[sacred mountain]

well im not wrong

[ivory sleet]

might be byte even

[native bluff]

seems like it doesn't support hex colors

Tried running the /team command and it didn't work with HEX

[brave sparrow]

I’m looking at the renderer to see

[tardy delta]

amplifier is int

[ivory sleet]

yes but in minecraft you cant have any higher than 255

[mortal hare]

have anyone used NIO V2 before?? hello??

[ivory sleet]

additionally its interesting since 129-255 iirc uses negative integers (when stored in nbt)

yes in api

tho thats not how game treats it

[quiet ice]

https://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/2021-12/R/eclipse-cpp-2021-12-R-win32-x86_64.zip try this I guess, it is a portable install so you can just delete the folder if eclipse turned out too confusing either

[quiet ice]

Yes

Though what is NIO v2?

[ivory sleet]

well yeah they're capped to the limit of shorts also in modern versions

used to be 35k or 36k or sth

[quiet ice]

35k

[brave sparrow]

@native bluff doesn’t appear to be supported

[mortal hare]

its java.nio since java 7

there were some packages of nio before that

[native bluff]

yups, that's what I thought. Thank you! 🙂

[ivory sleet]

I mean there's just nio and nio channels?

not sth like nio revamp afaik

[quiet ice]

Why would be use pre-java7 java?

[mortal hare]

Im not

im just calling that

ffs

Java I/O, NIO, and NIO.2

its a standard name

[ivory sleet]

interesting

[quiet ice]

yes, but specifing this is a bit strange, given that nowadays we all understand the same thing

[mortal hare]

i have such a question

lets say i want to serialize some data to files

ingame

should i use AsynchronoushFileChannel

[quiet ice]

At least in the progressive java world

[mortal hare]

to do operations async

and not to block main thread

[ivory sleet]

depends

[mortal hare]

also does Files interface blocks

[ivory sleet]

usually a ReentrantReadWriteLock is enough

myes

[mortal hare]

lets say i want to serialize data per player

not the init data

[quiet ice]

I'd use a simple FileOutputStream (you can dump the data off-thread and I do not think that there is a global FIO lock)

[mortal hare]

its binary type of data

i need to create binary file per player

[brave sparrow]

That’s fine

[sacred mountain]

I have 2 listeners, one is EntityDamageByEntityEvent (for the fireball hitting the player and setting the damage) and one is the PlayerInteractEvent (for throwing a fireball)
both of them currently work as intended, but im trying to add a message like this :

"Your fireball hit %count% entities for %damage% damage."
and
"You were hit by %playername% for %damage% damage with fireball"

How would i get the shooter and the player hit and use the message like that? i have a few options that i thought of:
i could put them both in the same class, but then i would need to let the damage event know who threw the fireball if multiple different players were throwing them at once

i feel like im overcomplicatnig my thought process

and its really simple

[mortal hare]

i don't want to use java.io specifically, since we have new apis since java7 to handle that

but im not sure about that actually

[brave sparrow]

Projectile#getShooter

[ivory sleet]

well

not everything in java.io is straight up trash

[mortal hare]

ik

Streams aren't for example

?paste

[undone axle]

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

[ivory sleet]

myes

[mortal hare]

if i dont specify ExecutorService inside AsynchronousFileChannel

what thread pool will it use

[ivory sleet]

I mean I'd say its the exception rather than the rule that sth is obsolete and should not be used when its contained in that package

iirc fjp common

[mortal hare]

i mean my binary files are quite small (1-5KB) uncompressed

so im thinking if i could use separate thread pool

[ivory sleet]

yes

calculate the blocking coefficient (if you have one) and maybe a fjp

[sacred mountain]

should i put them in the same class

i like it neater

[ivory sleet]

actually dovidas, it might not be the common pool

wouldnt make sense

[blazing scarab]

wdym i just use FileWriter and BukkitScheduler#runTaskAsync

[sacred mountain]

to have different evnthandlers in differnet classes

[mortal hare]

?paste

[undone axle]

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

[tardy delta]

doesnt matter

[mortal hare]

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

this is my current method of saving data

[tardy delta]

i like to put them per category

[mortal hare]

any ideas how to improve this

[ivory sleet]

depends on what you want to improve

[quiet ice]

why filewriter?

[ivory sleet]

but maybe write a unittest for it dovidas

[brave sparrow]

Like the listeners?

[ivory sleet]

to check that it works fine asynchronously

[blazing scarab]

Idk

[mortal hare]

well it does write it just fine

what should i test

[ivory sleet]

yeah file writer or buffered writer both cool stuff

[blazing scarab]

I havent worked with io by myself too much

[mortal hare]

same

[quiet ice]

does it have advantages over FileOutputStream?

[ivory sleet]

well

[quiet ice]

(other than the fact that you can write raw strings with it)

[mortal hare]

Writer is usually meant for text based streams

[blazing scarab]

At least it worked

[ivory sleet]

I mean FileOutputStream and FileWriter are kinda for different things

[blazing scarab]

oh

[ivory sleet]

(not entirely)

[blazing scarab]

I used writer for gson

[mortal hare]

Yea one's for byte transport

[ivory sleet]

^

[mortal hare]

and another for text based transport

[blazing scarab]

I wanted to use outpur streams, but that didnt work

[quiet ice]

okay, so I am not misusing it

[midnight shore]

Guys how can i get a random entry in an enum?

this is my method rn, and it is a little broekn

[young knoll]

Enum.values[random.nextInt(Enum.values.size)]

[ivory sleet]

I mean most common approach is to cache the enum values by Enum::values and then access a random index with sth like RandomGenerator::nextInt where you pass the length of the collection

[young knoll]

Except yknow, less ugly

[manic furnace]

I want to make my plugin use MySQL. It has to save a lot of data several times. How should i do that?

[quiet ice]

Just beware that .values() clones the returned array

[midnight shore]

omg i forgot that arrays have that option of getting an entry by [entry]

[lavish hemlock]

I'd personally recommend storing the array to a local variable and then using that

[young knoll]

Hence the less ugly

[blazing scarab]

Elaborate

[lavish hemlock]

Enum[] values = Enum.values();
Enum value = values[random.nextInt(values.length)];

[blazing scarab]

yes

[young knoll]

Looks too clean

To the void with it

[quiet ice]

I mean, the issue with this is that the .values() call is not fully cached

[midnight shore]

I already fixed it! ty

[blazing scarab]

i cant sleep if i know that my code does unnecessary computations

[midnight shore]

finally this is what i'm using

[quiet ice]

JIT might solve a few concerns but nothign is 100% sure

[midnight shore]

is it ok for you ProDevs?

[ivory sleet]

yeah altho iirc uses System methods to copy the array so should be kinda fast

but ye for enums like material

better cache it

[young knoll]

If your code isn't held together by toothpicks then it isn't worthy of spigot

:p

[ivory sleet]

🥲

[quiet ice]

I think it just calls Enum[].clone() (so it could be using jvm internals shenanigans to reduce ops)

[manic furnace]

What do you mean?

[quiet ice]

why use CustomItems#valueOf?

[ivory sleet]

oo ye good point

[young knoll]

Yeah why do you convert the enum entry to a string and then back to an enum entry

[blazing scarab]

We cant help yoy without knowing the context

[manic furnace]

OK. I create something, store the data. Later on i would delete/change the data. This Data has do bei persistant.

[blazing scarab]

ok

Whats the problem

[manic furnace]

I don't know how to make that with dbs. Should i keep the connection live? How should i do that?

[blazing scarab]

Go and learn sql and jdbc

[quiet ice]

(i. e. just yolo it)

There is nothing better than jumping head-first into the cold waters and then to come out screaming in pain

[manic furnace]

Ok i come when i am screaming 🤣

[tardy delta]

hikaricp

[midnight shore]

Because then I’m sending a message that says what item they added

So i need it as a string

[quiet ice]

but can't you just invoke .toString() later on?

[midnight shore]

Just wanted to make it simpler after

Because I’m actually using it like 10 times

[quaint mantle]

hey, so this is my first time making a plugin, and i have used gson to make a json file to store a class's contents in an array list, but when this function runs, it doesnt update the json

(it does create the file, though)

[hybrid spoke]

do you really want to create a new GSON and File object everytime the method runs?

[quaint mantle]

yeah so it overrides the current file (sorry if i sound stupid im coming into java from haxe)

basically i want to know why the file stays blank even when the method runs

and the arraylist does have contents

[blazing scarab]

that's nothing anyways

[hybrid spoke]

still unnecessary

boilerplate should be avoided

[blazing scarab]

what boilerplate

[drifting bridge]

How I can clear list of recipesUsed from furnace?
https://hub.spigotmc.org/javadocs/spigot/org/bukkit/block/Furnace.html#getRecipesUsed()

[hybrid spoke]

#clear?

[hybrid spoke]

but seems like there is nothing wrong. what if you use the writer to actually send the data, instead of gson?

[drifting bridge]

I testing it but i get this error

[22:36:07 ERROR]: Could not pass event PlayerInteractEvent to wiktorm v1.0.0
java.lang.UnsupportedOperationException: null
at com.google.common.collect.ImmutableMap.clear(ImmutableMap.java:877) ~[guava-31.0.1-jre.jar:?]

[quaint mantle]

i'll try that

[hybrid spoke]

otherwise it could be the file location. if that doesn't work, try to use this constructor instead https://docs.oracle.com/javase/8/docs/api/java/io/FileWriter.html#FileWriter-java.lang.String-

[hybrid spoke]

ah, an immutablemap. well, then i guess you can't except with some NMS stuff, but idrk.

[mortal hare]

is there any way to declare generic type inside the class like this?

public class Foo<Bar[]> {}

[blazing scarab]

Whats the point lol

[tardy delta]

record 👀

[mortal hare]

i have an interface with generics

[blazing scarab]

aaand?

[mortal hare]

and i need to have array as a generic type

[blazing scarab]

what's the problem

[mortal hare]

this doesnt work

[blazing scarab]

What

[hybrid spoke]

just use a list or any other collection

java doesn't support array generics

[mortal hare]

But its an Object

Array is technically an object

[hybrid spoke]

array generics

as you say, technically

[blazing scarab]

but it does?

[hybrid spoke]

internally its just a fixed order of objects, or primitives

[blazing scarab]

I dont understand your issue dovidas

[mortal hare]

lets say i want to create a class which already declares a generic type

with primitive type array

as a generic type

what you don't understand

[blazing scarab]

Thst doesnt make any sense

[hybrid spoke]

it do. java doesn't allow it.

you literally can't do that

[mortal hare]

it does make sense

[blazing scarab]

Why do yoy need a class wirh defined generic

it doesnt

[mortal hare]

because i have class implementation which doesnt need generic type anymore externally

[quaint mantle]

use c+

[blazing scarab]

please provide a context

[hybrid spoke]

doesn't matter. just use a list or any other collection impl you might need

[mortal hare]

ok this is weird

if it doesnt support primitive types as generic types

then why Class<byte[]> is legal

https://tenor.com/view/sxv-wtf-gif-23560064

[hybrid spoke]

java.lang.Class<**T**>

[blazing scarab]

cuz arrays are objects

[mortal hare]

You can provide byte[] as an object generic type inside variable declarations while you cant declare them inside the classes

weird.

Foo<byte[]> foo = new Foo<>(); // Legal

class Bar implements Baz<byte[]> {} // legal

class Foo<T> implements Baz<T> {} // legal

class Foo<Integer> {} // legal

class Foo<byte[]> {} // not legal

[blazing scarab]

Latter works as well

Because the last doesnt make sense

[mortal hare]

so does Integer

[hybrid spoke]

why doesn't Integer make sense?

[blazing scarab]

class Foo<UUID> {} woudlnt work i'm pretty sure

wtf

[hybrid spoke]

it does

[mortal hare]

it does

[hybrid spoke]

since its a class

[mortal hare]

byte[].class is also a class

its just weird handling

[hybrid spoke]

not explicit

[mortal hare]

im gonna just close this thought for myself

as weird syntax

[blazing scarab]

okay

Can you explain to me why do you need to define generics in classes

[mortal hare]

that was just me experimenting

[blazing scarab]

Doesnt that makes an UUID... A generic type?

Liks, not the actual java.util.UUID

or Integer

[mortal hare]

Could be

[blazing scarab]

And you cant have arrays since []

[mortal hare]

yea

its true

[blazing scarab]

That's it

[mortal hare]

solved

case closed 😄

[hybrid spoke]

welcome to generics

[mortal hare]

How evil would that be if someone named generic type as an existing class name

great for obfuscation i guess ( not much, but harder to read i guess)

[ivory sleet]

yeah, its an easy refactor

[neon minnow]

How to get an offline player in bukkit from an uuid?

[ivory sleet]

Bukkit::getOfflinePlayer

[neon minnow]

?? i am using the mojang api to get their uuid

you can't get an offline player if they haven't joined yet

[young knoll]

Sure you can

getOfflinePlayer(uuid) always returns an OfflinePlayer

[neon minnow]

Bukkit.getPlayer(UUID.fromString); im going to use this?

[young knoll]

No

That’s for online players

[neon minnow]

Explain

[young knoll]

And has to use their name

[neon minnow]

Oh

[young knoll]

Explain what

[neon minnow]

Wait

[young knoll]

GetPlayer requires the player to be online

GetOfflinePlayer does not

[neon minnow]

getOfflinePlayer is unresolved reference

[young knoll]

Bukkit#getOfflinePlayer

Oh wait you use stupid outdated versions

No idea if it existed then

[neon minnow]

Gets the player by the given name, regardless if they are offline or online.
This method may involve a blocking web request to get the UUID for the given name.
This will return an object even if the player does not exist. To this method, all players will exist.

'getOfflinePlayer(String!): OfflinePlayer!' is deprecated. Deprecated in Java

[young knoll]

Yes there are two methods

[neon minnow]

So this would probably slow down the main thread as it sends a request to mojang api?

[young knoll]

One for uuid one for string

Only the string one can be blocking

[neon minnow]

So, in that case, wouldn't an async function made by me be better that way that gets their uuid

[young knoll]

I mean

You’d just be doing exactly what the function does

[neon minnow]

some guy on spigot forums said that it would stop the main thread for a bit

[young knoll]

Yes

[neon minnow]

and slow the entire server, but if you do it asyncly?

[young knoll]

So do it async

[neon minnow]

Okay

was gonna us ethis

https://www.spigotmc.org/threads/getting-uuid-from-player-name-using-mojang-api.492896/

but ill just do the already existing bukkit one u said

Bukkit.getOfflinePlayer()

[mortal hare]

its thread safe?

[young knoll]

Sure

[neon minnow]

java.lang.ClassCastException: class java.lang.String cannot be cast to class org.bukkit.entity.Player (java.lang.String is in module java.base of loader 'bootstrap'; org.bukkit.entity.Player is in unnamed module of loader 'app')

var playerfromargs = args[0]
playerfromargs = Bukkit.getOfflinePlayer(playerfromargs).toString()
playerfromargs as Player

[mortal hare]

https://tenor.com/view/thumbs-thumbs-up-kid-thumbs-up-meme-brent-ramobjust-gif-19399510

[ivory sleet]

its probs thread safe, but not atomically safe (just a guess)

[neon minnow]

what am i doing wrong ?

[young knoll]

Trying to cast a string to a player

[mortal hare]

doesnt getOfflinePlayer() cache data?

[neon minnow]

my ide is telling me to

Bukkit.getOfflinePlayer(playerfromargs)

Type mismatch.
Required:
String
Found:
OfflinePlayer!

[ivory sleet]

yes which is why it might not be atomically safe

[mortal hare]

meh, i'd probably would've made http request by myself just to be sure im not screwing up something

[ivory sleet]

yeah, the entire disadvantage of abstraction is mainly concurrency

[mortal hare]

cache boolean or separate method would be enough for me to not to

[ivory sleet]

since its an "implementation detail"

but still needs to be concrete in apis (since hiding implementation causes concurrency update oblivion)

[neon minnow]

I still dont get how to to turn a uuid into a player

I got the uuid as string

now what

[mortal hare]

if you dont mind looking up data online on the main thread use the getOfflinePlayer()

[young knoll]

You already have a uuid?

[neon minnow]

I got the uuid

[young knoll]

Then just do getOfflinePlayer(uuid)

That one isn’t even blocking

[mortal hare]

but what if that player haven't played on the server

[ivory sleet]

still instantiates an object

tho name is null (along other things iirc)

[young knoll]

Mhm

[spare patio]

@Override
    public OfflinePlayer getOfflinePlayer(UUID id) {
        Validate.notNull(id, "UUID cannot be null");

        OfflinePlayer result = getPlayer(id);
        if (result == null) {
            result = offlinePlayers.get(id);
            if (result == null) {
                result = new CraftOfflinePlayer(this, new GameProfile(id, null));
                offlinePlayers.put(id, result);
            }
        } else {
            offlinePlayers.remove(id);
        }

        return result;
    }

1.8.4 implementation

[neon minnow]

java.lang.ClassCastException: class org.bukkit.craftbukkit.v1_8_R3.CraftOfflinePlayer cannot be cast to class org.bukkit.entity.Player (org.bukkit.craftbukkit.v1_8_R3.CraftOfflinePlayer and org.bukkit.entity.Player are in unnamed module of loader 'app')
myFunction.initializestuffs(sender as Player, finalOfflinePlayer as Player)

Dont get it

[mortal hare]

what version of minecraft do you use

[neon minnow]

1_8_R3

[ivory sleet]

ah nice then its not thread safe by the looks

[neon minnow]

1.8.8

[mortal hare]

I havent been using 1.8 for ages

sorry

[young knoll]

You can cast an OfflinePlayer to a player

[ivory sleet]

the other way around?

[lavish hemlock]

Nah

Player extends OfflinePlayer

[young knoll]

Player is always an OfflinePlayer

[lavish hemlock]

So, chances are, an OfflinePlayer could be a Player

[ivory sleet]

You cant cast OfflinePlayer to Player

[lavish hemlock]

Best to instanceof first

[ivory sleet]

yes exactly

[young knoll]

Or use isOnline

[lavish hemlock]

Ye

[lavish hemlock]

If you're saying you can't cast without doing a type check first

That's just untrue of the language

[neon minnow]

i did OfflinePlayer

instead

[ivory sleet]

Well, you know what I meant, anyhow point is as said there's no guarantee an instance of OfflinePlayer is an instance of Player

[lavish hemlock]

I didn't know what you meant until you said "yes exactly."

Say "You can't just cast"

[neon minnow]

How many requests can be sent to the mojang api

[young knoll]

Shh

[lavish hemlock]

Well, not infinite I know.

[young knoll]

This is why you use the built in method

It caches and such for you

[ivory sleet]

well usually you get your hands on a OfflinePlayer object so then it will objectively yield a ClassCastException if you cast it to Player

or

wwait

what am I even saying

its the reverse

I just said what you said before

[neon minnow]

can u get offline player name

like

.name.toString()

[ivory sleet]

myes

[neon minnow]

Thanks

[ivory sleet]

well using Bukkit::getOfflinePlayer by passing a uuid would yield an instance where the name might be null

[young knoll]

Don’t need the toString

[ivory sleet]

but else, sure if its cached

[lavish hemlock]

when you .toString().toString()

[neon minnow]

xD

lol

[ivory sleet]

might be using sth like components

[neon minnow]

I got

e.getRightClicked() as Player as a player

but how can i get their uuid

from this

[ivory sleet]

.uniqueId

[neon minnow]

thanks

[ivory sleet]

?jd-s btw

[undone axle]

https://hub.spigotmc.org/javadocs/spigot

[ivory sleet]

getters and setters become properties

[summer scroll]

Is this the same?

if(player.isFlying()){
  // code here
} else {
  if(player.isInWater()){
    // code here
  }
}

if(player.isFlying()){
  // code here
} else if(player.isInWater()){
  // code here
}

[lavish hemlock]

Yeah

[summer scroll]

Ah, intereseting

[lavish hemlock]

I mean they are effectively the same

[opal juniper]

elif 🤩🤩🤩

[lavish hemlock]

But there is one difference

You can put some code after that if in the else

And it will only run on else, no matter if the if was triggered

[summer scroll]

I want to do something If player is flying and in the water in this case.

[neon minnow]

sender.name.toString() returns uuid???
sender = OfflinePlayer

[summer scroll]

I always thought you need to put !player.isFlying() in the else if statement.

[lavish hemlock]

Well if the player is both flying and in water

Then use a logical and

&&

[summer scroll]

else if(player.isInWater()){ this mean the condition will be success if the player is not flying and is in water right?

[young knoll]

Yes

[summer scroll]

Alright, thanks guys

[golden turret]

that broke me 💀

[quaint mantle]

how do i save an arraylist to a .json, i have literally been trying to do this all day and the file stays blank

so can someone give me a snippet or something

[waxen plinth]

What is it a list of?

[golden turret]

an arraylist would be equivalent to a normal json list

[waxen plinth]

Depending on what's in there you might not need a json library at all

[quaint mantle]

a class

[willow stream]

can someone please give #942934911432687656 a look?

[waxen plinth]

Could you be more specific

Like do you literally mean it is a List<Class<?>>?

[quaint mantle]

ArrayList<Menu>

the class is called menu

which opens the inventory and handles the customizations

[waxen plinth]

Okay then that's really important information that you left out

You're gonna need a way to serialize the Menu instances

[quaint mantle]

how would i do that (sorry i am new to java)

[waxen plinth]

You need some way to convert it to a string, basically

[quaint mantle]

alright

[waxen plinth]

And then back

[quaint mantle]

this is what i came up with

String menu = new Menu(name, size, new Menu.OptionClickEventHandler() {

        public void onOptionClick(Menu.OptionClickEvent event) {
            event.setWillClose(true);
        }
    }, this).toString();

right now i am just saving it

so i will worry about destringing it later

[waxen plinth]

Not like that you won't

You can't just call toString() and expect something deserializable to come out

The standard toString() implementation just gives the name of the class and its location in memory

Which is useless for persistence

You need a way to actually convert all of the relevant data to a string

And you have an anonymous class definition in there so that's gonna be quite hard

[quaint mantle]

oh so not the whole class

just the variables that need to be read

[waxen plinth]

Why are you trying to save this to a json file exactly?

[quaint mantle]

well it doesnt really matter i could do yml but i tried that earlier

[waxen plinth]

It does matter

Why are you trying to save this

It's very strange to try to save something like this to a file

[quaint mantle]

it doesnt really matter what file it is

not why

[waxen plinth]

That's not what I'm asking

Why are you trying to save this

[quaint mantle]

so when the server shuts down people don't lose the menus they have created

they need to be stored somewhere

as well as the name, items, etc.

[waxen plinth]

And how are the menus created?

How does a player create a Menu?

[quaint mantle]

/menu create

[waxen plinth]

In the code

[lost matrix]

Thats not a trivial problem. Designing classes to be serializable is an art in itself.

[waxen plinth]

What variations are there

[worldly ingot]

I just wouldn't expect that ever under any circumstance, even if docs say it is ;p There really should be a designated serialization method and toString() should be reserved for human readability

Just a random aside I wanted to throw in there

[waxen plinth]

They can overlap considerably

My serialization methods tend to be human-readable

But yeah it often does make sense to separate them

[worldly ingot]

It's rare. Few cases for that are things like enums

[waxen plinth]

A Menu takes an event handler of some kind

That's what's going to make serialization difficult here

If there are a preset number of possible values then you can just assign names to them and be done with it

Otherwise it's going to be a lot more complicated

[lost matrix]

He would need to define a fixed set of actions with serializable context.

[waxen plinth]

Yeah I guess "assign names to them and be done with it" is a bit simplistic

But it really is much much simpler if that's how this works

[quaint mantle]

when a player runs /menu create {size} {name} it is SUPPOSED to add the size and name, items, and commands items do when clicked to an array, which would be stored in either a yml or json depending on which works

[waxen plinth]

But what other properties does a menu have?

Size and name are clearly not the only ones

It's probably the items in there, right?

The behavior of the menu - can each item have a different handler that is run when it's clicked?

[quaint mantle]

yes

edited above

[waxen plinth]

Right, that's where it gets complicated

So does each item have only one command attached to it?

Are there any other things an item can do when it's clicked other than just run a command?

[quaint mantle]

yes, you cannot add more than one to an item

[quaint mantle]

no, just run a command

[waxen plinth]

Okay

Then that's doable

Now you have a few choices

You could do all of this yourself

Handle serialization of everything, including the items, which is gonna be very annoying

Or you can use a pre-existing library that will handle the serialization for you as long as you tell it how

[quaint mantle]

any good ones

?

[waxen plinth]

I've made one that you could use for serialization to yaml

For json there's gson which I believe works similarly

[quaint mantle]

i tried gson earlier but it did not work

[waxen plinth]

You can also use ConfigurationSerializable which is built into bukkit

[quaint mantle]

file would create but not update

[waxen plinth]

Yeah most likely you were using it wrong

is

[grand venture]

This does not make sens right?

`@EventHandler
public void onPlayerRespawn (PlayerRespawnEvent event) {
Player player = event.getPlayer();
player.teleport(new Location(player.getWorld(),97, 242, -143));
if(!player.isOnGround()) player.setGliding(true);

}`

[waxen plinth]

Make sense how

It's valid code

I don't know why you would do such a thing but it would work

[grand venture]

But it doesnt work 🥲

[low temple]

Hey, does ```
FileOutputStream output = new FileOutputStream(file);
ObjectOutputStream stream = new ObjectOutputStream(output);
stream.writeObject(object);

Allocate the same amount of memory as 

new ObjectOutputStream(new FileOutputStream(targetFile)).writeObject(object);

?

[waxen plinth]

Why would it not

It will take the same amount of heap space

It will use very slightly less stack space, but that barely matters at all

Take readability over that micro-optimization

[low temple]

So no reason to use one or the other? Just impacts readability?

[waxen plinth]

Readability is more important here

The stack allocations of a few variables uses such a negligible amount of memory that doesn't even need to be garbage collected

[low temple]

gotcha thanks

[grand venture]

The player will just be spawned at the World Spawn Point. But player.setGliding(true); works, why does the teleport not work?

[worldly ingot]

because the teleported location will be overridden by the actual respawn

Use https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/player/PlayerRespawnEvent.html#setRespawnLocation(org.bukkit.Location) instead

[grand venture]

[quaint mantle]

I'm querying db "mysql/SQLite" for each online player every 5 min. Would I just use a for each loop on online players and inject playerdata into db ? Or do something like hashmaps ? Im not sure if db can handle a loop like this or what is most commonly used to do this.

[muted sand]

how do i change a large area of blocks?
I use a for loop, and theres just a small visual lag of the for loop working, and it just bothers me :}

[sharp flare]

loop

[lost matrix]

https://www.spigotmc.org/threads/guide-on-workload-distribution-or-how-to-handle-heavy-splittable-tasks.409003/

[muted sand]

oh

okay!

i go learn more java

[lost matrix]

You keep your data in memory while the players are online and store the data when a player disconnects.
Additionally you can also backup the data every 5minutes. But this should not be done with a loop but a single query that delivers all data.

[quaint mantle]

Makes more sense thanks!

[muted sand]

Additionally you can also backup the data every 5minutes. But this should not be done with a loop but a single query that delivers all data.
so it'll cause less strain on the database?

[drowsy helm]

yeah one single data dump every so often is better than constant r+w

but also runs the risk of data loss if the server goes off line, the cache of data will be lost

[muted sand]

how would one go about doing that?
a for loop that just appends to some sort of an Object?

[drowsy helm]

well personally i used to cache to redis then dump that every so often

[muted sand]

oh that sounds smarter

[drowsy helm]

but if you are only using 1 db just have a db manager that stores objects then writes later on

[muted sand]

wdym by a db manager-?

[drowsy helm]

just a class that manages the db IO

[muted sand]

oh

[drowsy helm]

or just create your statement, save it to some sort of array

or queue

then dump all those statements

[muted sand]

ooh okay!

and would redis be better opposed to using variables for a caching? (or does this just matter on usage cases?)

[drowsy helm]

yeah depends on usecase tbh. Only reason i used redis is for redundancy

if your mc server goes offline, redis will still have the data

whereas if you didn't have redis you would just lose the data

[young knoll]

I just write every change :p

[muted sand]

unless your entire host were to magically poof 🤡

[young knoll]

Reads are heavily cached though

[drowsy helm]

separate servers pog

yeah depends on what you are read/writing

[hybrid spoke]

because of that large networks do have many servers

[muted sand]

aight

[hybrid spoke]

with many backups

[drowsy helm]

if its not super taxing i wouldn't bother even caching it

[hybrid spoke]

at different locations

[muted sand]

yea i suppose

[drowsy helm]

theres some nms methods that are far faster

[sullen marlin]

World#setType or whatever will be very slightly faster (on 1.18.1 anyway)

the 'fast' nms methods are a scam

setType without physics is as fast as you'll get without breaking things

[neon minnow]

Is it possible to have an on click that would then open the player's chat and write a command in for them, for example when they click their inventory item it would open the chat and write "/help" but not actually execute it (just show it)

[young knoll]

No

Only chat components can do that

[worldly ingot]

I mean, kind of

Could reflect into the CommandMap, #get() the command and invoke its execute() method

That's ugly and hacky as hell, and I seriously don't advise it

but you can do it lol

[young knoll]

But that doesn’t just show it

Besides, why not just performCommand

[worldly ingot]

but not actually execute it
led me to believe they want to avoid that lol

[young knoll]

Isn’t that what the execute method does

[worldly ingot]

afaik it does still perform and log the command

[neon minnow]

I want it to be like how JSON does it, it sends a player a reccomended command.

[worldly ingot]

oh you want command suggestions

yeah that's only done with components. You can't do that any other way

I misunderstood the original question I guess lol

[neon minnow]

No you understood right first time

Not a suggestion where it shows possible commands in a black box in chat, but actually write it in the player's chat box so then they can finish it by writing the arguments in

but i guess that cant be done.

[worldly ingot]

Yeah that's a command suggestion done with components

[neon minnow]

Only with the json chat component

Ok thanks

[low temple]

Does anyone know the proper way of getting a player’s DisplayName as a String in 1.18.1? The Player#getDisplayName() is deprecated. Still works but is there a better way to get someone’s display name?

Im working with EntityPlayers right now to create NPC's, how can I make an Entity sit on another one? Do i have to use packets for this? Im in 1.8

[storm crescent]

How would I update a player's gameprofile to have a different uuid? I'm trying to make a custom profile plugin where players can have different profiles. When I change the gameprofile uuid, the getUniqueId method still returns the original uuid.

[lost matrix]

1.8 is half a decade old and lost support years ago... Go search in old forum posts.

[neon minnow]

Lmao, im literally looking on youtube right now. im just talking about entities and how to make them sit on other ones?

because i cant find much about that

like

[lost matrix]

This will break a lot of plugins. Im not even sure if this is possible on an online server.

[neon minnow]

riding a pig

how would you code that

[lost matrix]

Depends on the version you are using

[neon minnow]

does it really though

[lost matrix]

If you use nms then it matters a LOT.

[neon minnow]

Not using it??

[storm crescent]

Yeah I'm trying to make this plugin work with most plugins, essentially giving the player an entirely new account. I've seen client-side uuid change but I'm not sure about server-side.

[young knoll]

EntityPlayer

[lost matrix]

EntityPlayer is a nms class

[neon minnow]

oh yea nvm

[lost matrix]

You will have to reconnect the player for that because his UUID will be used for internal mappings. Example Bukkit.getPlayer(UUID) accesses a Map<UUID, Player>
If you just change the GameProfile then this map wont be changed and the old UUID mapping will remain. And thats just one place.

So you will have to hook early into the handshake.

[lost matrix]

Would be worth looking at the protocol to see where a good place for injection would be.
Im actually not sure if thats even possible.

[hardy swan]

you mean you wanna regenerate the entire world?

[lost matrix]

Talking about just setting the block type at a location. Dont bother with nms.
If you want to change huge areas of blocks then you should do it async.

Async does not mean from a different thread. If you split the task over several ticks then thats an async action.

Example: You have a million blocks that need regeneration.
Doing this in one tick will crash the server. But placing 20k blocks every tick for 50 ticks will probably be fine.
It wont lag and only take about 3 seconds.

You can also just place 1k and wait for 30 seconds and dont even lose 0,1 TPS. Shouldnt really matter.

[ancient jackal]

I'm trying to navigate to latest.log in the logs folder but getting the parent file beyond /plugins is returning null
earlier it was said spigot doesn't prevent it but... does it?

        System.out.println(f.getAbsolutePath());
        System.out.println(f.getParentFile().getAbsolutePath());

spigot cant do anything like that

[ancient jackal]

is there a way for me to reach latest.log?

[lost matrix]

Sure. You have java at your disposal. You can do anything. As long as the os allows it.

[ancient jackal]

Thank you, I will try that

[lost matrix]

  public File getLogsFolder() throws URISyntaxException {
    File spigotFolder = new File(Bukkit.class.getProtectionDomain().getCodeSource().getLocation().toURI());
    return new File(spigotFolder + File.separator + "logs");
  }

In most cases this will also work:

  public File getLogsFolder() {
    File spigotFolder = Bukkit.getWorldContainer();
    return new File(spigotFolder + File.separator + "logs");
  }

[ancient jackal]

oh shoot I just raw dogged it, didn't know those methods existed

        LinkedList<String> oldPath = (LinkedList<String>) Arrays.asList(f.getAbsolutePath().split("\\"));
        oldPath.removeLast();
        oldPath.removeLast();
        oldPath.addLast("logs");
        oldPath.addLast("latest.log");

        String newPath = oldPath.getFirst();
        for (int i = 1; i < oldPath.size(); i++) {
            String s = oldPath.get(i);
            newPath = newPath + "/" + s;
        }```

Eh let them choose what they want for a private project

Just do understand that working with 1.8 will be harder than newer versions

[gritty urchin]

not really

if anything its easier

cuz it doesnt have the extra shit

[eternal night]

👀👀 a wild take

1.8 is missing a lot of API that can be pretty helpful even outside of the API that represents gameplay additions

[neon minnow]

What are you talking about? If youre going to say something at least explain it or give actual examples

[neon minnow]

1.18 is so bloated + servers require like 2Gig ram each, now tell me, how are you supposed to launch a big network based on 1.18? You can't, each instance of a lobby / minigame will be like 2 gig each, with 1.8, what? its like 400mb. usage, or smaller plus, its so simple, and the fact that i have to learn packets and shit, just better for me as i can get even more understanding and learn more

[lost matrix]

bollocks

[neon minnow]

haha, youre funny, i went onto the papermc server, got laughed at for using 1.8, so i tried out 1.18, my entire pc nearly crashed, 100% cpu usage, and i had to put at least 1 gig ram. whilst 1.8 can easily just fine with 400mb using 200mb currently, on my server

1.8 is simple, yes old, but simple

[eternal night]

You are still using outdated software. If neither spigot nor paper were kind enough to supply you with a fix for log4j, you'd be stranded.

[neon minnow]

for most people new versions are recommended -- yes. but let people choose what they want to play with

[neon minnow]

True but they did, because a lot of people are still using 1.8

[eternal night]

In terms of API, PDC, NoAI, MaterialTags, all that good stuff

[lost matrix]

1. You dont need to support thousands of concurrent users. You are not Mineplex.
2. 1.18 is more than capable to handle a metric ton of users if you know what you are doing
3. Its all a matter of setup. If you know what you are doing then 1.18 is as capable as 1.8 when it comes to minimalist setups

[eternal night]

idk where people get the "a lot of people are using 1.8" from

bstats screams otherwise

[neon minnow]

most 1.8 users turn bstats off anyways

I am using scoreboards to set the scoreboard of the player, but i dont really know how to set the player to more teams (because nametags with prefixes) interfere with scoreboards and then one gets removed, so in my current implementation both cant be running at the same time? do i have to make fake scoreboards or something

[lost matrix]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/LivingEntity.html#setAI(boolean)

no that breaks the "move around and in water" afaik

Is that decided by the entities AI?

Eeeh IIRC

might be wrong

[woven phoenix]

So is there no simple way?

[eternal night]

I might be thinking of no gravity

Well try the NoAI flag

[lost matrix]

^

Might work. If not then you need to clear their AI goals.

[woven phoenix]

Alright ima try

How do I even do that NaAi flag 💀shi look confusing

[eternal night]

Eh I mean, if you just want suffix/prefix then have either one scoreboard globally or (if neeeded) every player gets their own scoreboard and you have to maintain all players teams across all scoreboards

Well with that method o.O

[lost matrix]

You literally call the method with a boolean ^^

[eternal night]

final LivingEntity e = world.spawn(loc, Zombie.class);
e.setAI(false);

No idea what a Boolean is

you are coding a plugin right ?

[woven phoenix]

Oh this is for coding plugins 💀

[eternal night]

yeeaaa

[lost matrix]

...

[woven phoenix]

🤣🤣

Whooops

[eternal night]

if you just want to spawn one in game you do

/summon sheep ~ ~ ~ {NoAI:1b}

as a very basic example

[woven phoenix]

But is that permanent

[eternal night]

yea

that is persisted through restarts

however, again, you'll have to see if that is actually what you want to happen

[woven phoenix]

Say like I have blaze spawners and I do that with blazes will they still spawn fall flow in water and not attack me

[eternal night]

?tryandsee

[undone axle]

https://tryitands.ee

[woven phoenix]

Alright

[eternal night]

tho for blaze spawners to all spawn blazes with that tag

[lost matrix]

If you let the spawner spawn an entity with that flag

[eternal night]

you'd either need a plugin or some active command blocks

or yea, custom spawners

[lost matrix]

Cant you specify a nbt String for custom spawner? Or did he mean naturally generated ones.

[woven phoenix]

I have silkspawners

I think it works

So they don’t attack me but they can still walk

[eternal night]

Are you talking about a connection pool ?

like hikaricp

[blazing scarab]

You always should

[lost matrix]

Meh. Not sure i

f it makes sense with sqlite

Probably good practice still

[blazing scarab]

supporting Sqlite only is meh

[neon minnow]

Postgres?

Is it good?

[drowsy helm]

yep

[neon minnow]

nice

[tender shard]

why do people always confuse this channel with help-server

[dusk flicker]

no idea

It happened so often

[mortal hare]

i never realised that you can do something like this:

for (ItemStack itemStack : player.getInventory()) {
                
}

Inventory interface extends Iterable

you don't need .getContents() to iterate through the items

but sadly InventoryView doesnt implement iterable interface

[lost matrix]

Would be a bit weird because it doesnt contain ItemStacks itself. It just represents the view of 2 inventories.

[mortal hare]

it could still be iterable

it could iterate all of the items (including player's)

[dire marsh]

ah yes, im a developer, i can edit config.yml

[neon minnow]

Guys, anyone know how to send a title with subtitle? Thanks

[opal juniper]

does changing an enum that other plugins have already compiled with cause issues? like do they rely on the ordinal under the hood

[chrome beacon]

You need NMS and packet in 1.8 iirc

[neon minnow]

Thanks ill do that

[lost matrix]

In 1.18? Just call sendTitle() 😄

[neon minnow]

in 1.8

im using NMS

[lost matrix]

You can even specify fade in fade out time

[neon minnow]

yah thats cool

[eternal night]

Damn I never knew newer API has those cool feaures smile!

But yeah, Google once and you should find the respective Packets

[lost matrix]

Astounding, right? Its like people improved the API in the last half decade.

[neon minnow]

lol

[dire marsh]

b-b-but old versions are so much simpler to use!

No complex API additions like that dum PDC!

[lost matrix]

Sometimes i which that old versions would have been left out from CVE-2021-44228 patches.
Was an opportunity for a big cleansing.

[dire marsh]

people would have just downloaded a plugin to fix it

[lost matrix]

How would you fix this with a plugin? This was a vulnerability with the logger internals.

I guess with some regex...

Still

[dire marsh]

there were plugins made that intercepted it using packets

[neon minnow]

It is literally so simple, i added 5 lines of code for packets, and made it into my own function so i can easily do SendTItle(player)

Whilst having the efficiency and speed of the server with only 200mb memory usage

something a 1.18 server will never be able to achieve.

[opal juniper]

you could fix it with packet catching like Sam said

but eh, i mean whatever

200mb ram, zero features

https://tenor.com/view/srg-bülach-weighing-things-gif-13323220

[lost matrix]

You are making the wrong design choices, but ok...
Do you even have a playerbase worth sacrificing that much API and features for?

Increasing your development time by years just to have 20 players on an outdated piece of software

[dire marsh]

@neon minnow what server type

[lost matrix]

Its 1.8 so it has to be PvP/Minigame stuff

[blazing scarab]

Or factions with laggy cannons

[young knoll]

You gotta use a cannon fork 🤡

[buoyant viper]

i mean as far as the jndi part goes mojang themselves had released a fix

[warped panther]

Config get differnt value in a while loop

[buoyant viper]

the regex filter

[willow stream]

can someone please check out #942934911432687656 ? I'm trying to make it so the cube goes behind the player if it goes over his head

[elfin atlas]

Does someone know what this effects are?

[chrome beacon]

Guardian rays

[elfin atlas]

All 3 of them?

[chrome beacon]

Probably

[drowsy helm]

2nd is just a bunch of music notes

3rd is guardian ray

[chrome beacon]

Ah

[drowsy helm]

No clue what 1st is

[elfin atlas]

Okay

Hmm still thinking about what the 1st is

[chrome beacon]

Looks like the ender dragon death beam

But this one is fully white

[neon minnow]

This ^

[elfin atlas]

Is there a way to make it full white?

[chrome beacon]

Try killing an ender dragon in the overworld

See if it's white

I'll check back later

[elfin atlas]

Okay

But how would I’ll spawn effects like this?

[gritty mist]

hello I missed the method for creating a formated text like "&1H&2E&3Y" instead of doing ChatColor.BLUE + "H" + etc...

[quaint mantle]

does this db query cause heavy load to db ?

[blazing scarab]

Use batches

Also object oriented programming is a thing

[buoyant viper]

ChatColor.translateAlternateColorCode

or something like that

[quaint mantle]

why dont just reuse the queryhashmap thing for the first method?

instead of copying the codes over

just call the method with 5 mins

prob more readable code?

phwwww just realized they are two different codes

ah yea 😄 np

[neon minnow]

I got player.location, how can i add +5 to it at Y coords?

Thanks

[hollow bluff]

player.location.getY

create a new location and add thst for the y

Location location = new Location();

[neon minnow]

ty

[spiral light]

or just location.setY(location.getY + 5) ? thats simple stuff you should know

[neon minnow]

dude, chill, i was wondering because im new to locations and shit. anyways, i figured it out, and yes, in the end i did use your method.. but im trying to get a whole location so i just did new loc with location.getx, location.gety + (variable), location.getz

just a question, how can i do async in a function?

trying to do object : BukkitRunnable() { } but it doesnt let me

[spiral light]

?schedular

?schedule

?scheduling

[undone axle]

https://www.spigotmc.org/wiki/scheduler-programming/

[spiral light]

^^

[neon minnow]

Yep

i read

it says to do new BukkitRunnable() {
/* the usual code */
}.runTask(plugin);

but i cant do that in function

[spiral light]

what do you want to do and show code of what you want to do

[tardy delta]

just use lambda expression instead of new BukkitRunnable

[neon minnow]

I have a function. I want to thread sleep inside of it, but to do that i need to make it async. I cant make it async inside of the function, because bukkitrunabble turns into object: BukkitRunnable in Kotlin, and object cant be used inside function.

[neon minnow]

? sorry what u mean

[spiral light]

sounds like

?xy

[undone axle]

http://xyproblem.info/

[tardy delta]

stupid kotlin

[spiral light]

i believe he is doing it wrong anyway

[tardy delta]

there should be a way, shouldnt make sense otherwise

[neon minnow]

Do you understand what i am trying to say

[tardy delta]

yes

[tender shard]

wdym object can't be used inside function?

although I don't like kotlin, I gotta add that this statement is not true

[neon minnow]

its not letting me for some reason

[tender shard]

show your code pls

[neon minnow]

nvm fixed

So its safe to do

thread.sleep

in an async bukkit ?

[tender shard]

yes

[tardy delta]

uhm kinda but why would youN

[young knoll]

I mean

I guess you could easily delay stuff further inside an already delayed task

[neon minnow]

delaying

in for loop

[young knoll]

Afaik async tasks use a thread pool

So sleeping them may still be a bad idea

[tender shard]

as long as you don't have thousand threads, I don't see any problems in putting one of them to sleep

just be sure to include a nice catchy lullaby before doing so

[vocal cloud]

Just schedule the task instead of sleeping the thread
