iam downloading all ver i need

#

the problem is with

#

maven / intellij idea

eternal oxide
#

what problem?

twin venture
#

before you tell why i use old ver , i dont this is only for test .. :
i tried all version

unknown.png
#

same problem

#

the api is working and recognized my maven

#

but the spigot is not

eternal oxide
#

You can;t import both in the same pom. Theres no way for Intelij to know which API you want to use

#

oh api and spigot

#

did you run buildtools for 1.8.8?

twin venture
#

well its 1.8.8 isn't it ?

#

or 1.8.9?

quiet ice
#

188, 189 is clientside only

twin venture
#

i downloaded 1.12.2 , 1.13.2 , 1.16.5

eternal oxide
#

spigot 1.8.8 you get by running buildtools

twin venture
#

and i can't seems to use them ..

#

inside intellij idea

eternal oxide
#

api gets downloaded from spigot

twin venture
#

yes but sometime i need to use some nms

#

or packets

eternal oxide
#

run buildtools and build 1.8.8

quiet ice
#

In that case you need to build the package via buildtools

#

hi did someone know a good tablist plugin?

#

for my smo server

twin venture
quiet ice
eternal oxide
#

oh my, are you ignoring me?

fringe latch
#

Distinguish 1.17 and 1.18 NMS (Maven)

quiet ice
undone axleBOT
twin venture
#

thank you anyway ..

quiet ice
#

Well you also need to run buildtools

twin venture
#

wait i have a question

quiet ice
#

With --rev 1.8.8

eternal oxide
quiet ice
#

^

twin venture
#

files are in

#

users

#

not in m2

#

not in here :

unknown.png
quiet ice
#

bt should also install the artifacts to maven local

twin venture
quiet ice
#

Are you sure that they are not there

twin venture
#

2 minutes ago

#

wait let me try ..

quiet ice
#

I don't see what the issue is - you know what you are doing so ???

twin venture
#

that seems to fix the issue thanks 😄

junior briar
#

would getHighestBlockYAt(x, z, HeightMap.WORLD_SURFACE) be out of ceiling of the nether?

rough basin
#

How to use .yml for saving data?

vale ember
#

how do i do that with maven?

red sedge
eternal oxide
quiet ice
#

If that is possible on maven it is def. possible on gradle

eternal oxide
#

maven uses teh specialsource plugin to remap

quaint mantle
#

Use paperweight...

red sedge
vale ember
quaint mantle
#

what error

peak granite
#

is it possible to have a timespan like "5 minutes", "3 seconds", "2 hours" for a command arg

quaint mantle
#

Yes, but you'd need a parser

vale ember
#

"There was a failure while executing work items
A failure occurred while executing io.papermc.paperweight.tasks.FixJar$FixJarAction
Cannot invoke "String.charAt(int)" because "internalName" is null"

quaint mantle
vale ember
quaint mantle
#

Aha

vale ember
#

but how can i make sure that api features on 1.18 will work on older versions?

quiet ice
#

I'd say it's an issue with the java version of 1.18

quaint mantle
#

Try using older paperweight version

#

Like 1.2.0

vale ember
#

i use 1.2.0

#

and it gives the error

#
  • in paper chat they said that it have no support for versions like 1.13
quiet ice
#

Yeah, mojmap is only there since 1.14

peak granite
vale ember
quaint mantle
#

yes, but spigot does not support it neither

#

special source works only on 1.17, right?

chrome beacon
#

1.16.5? (maybe) and 1.18.(1) should have it too

quiet ice
noble lantern
quiet ice
#

either way mojmap is rather new

junior briar
#

oof. is there any detail of HeightMap?

noble lantern
#

What do you mean and what are you trying to achieve?

eternal oxide
vale ember
#

i'd like to have support for 1.13-1.18 or at least 1.16-1.18

#

how can i do that with gradle?

quiet ice
#

1.13-1.18 is impossible, that far is clear

quaint mantle
#

only nms right? use module man

#

module

vale ember
#

yes

quaint mantle
#

pom.xm- wait you use gradle idk

vale ember
#

yes

junior briar
quaint mantle
#

maven have each pom.xml for each module if you want lol

#

Well, you Just use spigot mappings on modules for 1.13,1.14.4 and mojang mappings on 1.17+

quiet ice
#

unless you'd go with spigot -> official -> searge -> mcp, but I don't know anything that exists for this

vale ember
quiet ice
#

Well, perhaps minimappingsviewer has something for that

quaint mantle
#

Gradle has build.gradle for every module as well

#

well, spigot mappings arent too bad on > 1.17

junior briar
#

it's like, would there be more blocks above a WORLD_SURFACE?

vale ember
#

do i need to shadowJar nms?

#

or just include it as dependency?

quiet ice
#

nms should be compileOnly

peak granite
#

@quaint mantle

#

if i'm making a function

#

to convert it to a timespan

#

what would the returning type be

#

TimeSpan doesn't work

quaint mantle
#

Duration

peak granite
#

oh

drowsy sapphire
#

Is there a PersistentDataStorage for 1.8.8 plugins?

quaint mantle
#

No

#

Do not use 1.8.8

drowsy sapphire
quaint mantle
#

update

quiet ice
#

especially with the log4j bug people should not use that version

drowsy sapphire
#

can i run a 1.18 plugin on a 1.8 server

peak granite
#

obviously not

drowsy sapphire
#

bruh

quaint mantle
#

do you have a reason to keep the server on 1.8

#

You miss so much cool stuff

young knoll
#

Muh PvP

hoary pawn
#

how can i make autocomplete work for second args?

drowsy sapphire
twin venture
#

.. help?

unknown.png
young knoll
#

Streams moment

quiet ice
#

I'd avoid using custom data structures

twin venture
#

you mean use stream insted?

quiet ice
#

No, they imply that this issue is caused by the streams api

young knoll
#

Why have you made your own bimap

quiet ice
#

Which may very well be the case, but I would say that it is a programmer error on whoever coded #getEntry

twin venture
#

its working 100%

#

but

#

its make some lag after 1-2 day's of server running ..

quiet ice
#

You see, there is a difference between

Object o = map.get(key);

and

Object o = null;
for (Map.Entry<Object, Object> e : map.entrySet()) {
    if (e.getKey().equals(key)) {
        o = e.getValue();
    }
}
assert o != null;
#

this is my favourite example because I closely work with a codebase that uses latter approach far too often

twin venture
#

iam using the code above to check y , yaw and rotate an entity

#

armorstand in this case

young knoll
#

I’m still wondering why you’ve made your own bimap

quiet ice
#

Well, the important thing is what the bimap does

#

the impl of the bimap is at fault, not the caller code

twin venture
young knoll
#

Use the bimap from guava

quiet ice
#

^

#

It is baked in into minecraft so no issue using it

twin venture
#

or should i change the whole code?

#

the Bimap i use have 3 values

quiet ice
#

Also, I'd get rid of the asserts, that'd improve the performance by the factor 2

twin venture
#

ok

young knoll
#

You want a map with 1 key and 2 values?

#

Just use a normal map and make a class that holds the 2 values

quiet ice
#

Then use Map<K, Map.Entry<V1,V2>> instead

young knoll
#

That also works

quiet ice
#

I overuse the Map.Entry interface tbh

twin venture
#

for testing puprose like this : ?

unknown.png
quiet ice
#

Could I take a look at your Bimap class? I want to be sure that we are actually suggesting the right thing

twin venture
#

can i screenshare?

#

or?

quiet ice
#

?paste

undone axleBOT
twin venture
quiet ice
#

Otherwise you'd have 200 screenshots, those fellas can be enormous

twin venture
quiet ice
#

private List<Entry<K, V, V1>> data = new ArrayList<>();, well that explains the shoddy performance

quaint mantle
young knoll
#

map.get doesn’t use a loop?

#

Lul

quaint mantle
#

lul

twin venture
#

can you explain a little bit why its bad?

quiet ice
# 
    public void replace(K key, V value1, V1 value2) {
        if (!getEntry(key).isPresent())
            return;

        Entry<K, V, V1> entry = getEntry(key).get();
        entry.setValue1(value1);
        entry.setValue2(value2);

        this.data.set(getDataIndex(key), entry);

the this.data.set[...] is useless here

twin venture
#

i didnt make that class , a friend i know did make it and he told me that i can use it .

vale ember
#

anyone here worked with spigradle? if yes, how to change debugSpigot mc version?

young knoll
quiet ice
#

I'd avoid using that class, it is an optimisation nightmare

#

There are major cardinal sins that were committed here

twin venture
young knoll
#

We already told you

quiet ice
#

Anything with a complexity of O(1)

twin venture
#

Map<K, Map.Entry<V1,V2>>

#

i tried that

#

gave me more errors xd

#

more i tried to fix more new errors apear

quiet ice
#

The other solution would be to rewrite the bimap class to have a runtime complexity of close to O(1), should be rather straightforward

young knoll
#

The name is weird

#

It’s not a bimap

quaint mantle
#

Damn why not just Multimap

young knoll
#

Don’t those require the values to be of the same type

quaint mantle
#

oh right

quiet ice
#

public interface Multimap<K, V> { yep

young knoll
#

Just make a class to hold the two values

quaint mantle
#

^^

young knoll
#

Or use something that already exists to hold 2 values

#

Like a pair

quiet ice
#

Or map.entry

quaint mantle
#

generics are ugly so

quiet ice
#

Ah yes, using highly specialised records

arctic moth
#

any way to change the damage ticks

#

ive seen it before

#

on those pvp servers

#

they have it so like every damage registers

#

no invincibility period

young knoll
#

Sounds horrible

#

.setNoDamageTicks and .setMaxNoDamageTicks

twin venture
#

what is the best way that won't cause any lag ?

#

i tried to use packets / to spawn / rotate entity but it didn't work out well for me ..

young knoll
#

We already told you to fix your data structure

quiet ice
#

The importance of the proper data structures are underrated by many for some reason

arctic moth
twin venture
#

thanks will do

arctic moth
#

ik this is more an intellij thing, and ik its simple, but why does it remove the ability to add a class when the pom.xml is added? its super annoying. also, it doesnt highlight text in those classes

fading lake
#

thats odd

arctic moth
fading lake
#

full screenshot, i.e where you're clicking

#

the entire explorer window

arctic moth
#

its just right clicking package

fading lake
#

can you show me your project window?

#

if you wanna keep it private, DM me it

#

seems like a maven loading error

arctic moth
fading lake
#

yeah thats a maven loading error

arctic moth
#

wait

#

why is there 2 imls

#

xD

fading lake
arctic moth
#

il

#

its never happened before

#

i did it exactly the same

fading lake
#

yours doesnt have the main or java directories 🤔

arctic moth
#

o

fading lake
#

try forcing them in and see if it fixes itself

#

yeah because there's supposed to be a resources folder for your pluginyml too, it might be better just making a new project with maven from the start so it creates the directories properly

arctic moth
#

normally i dont need a main or java folder

fading lake
#

thats... not good

arctic moth
#

wait so how would the whole thing look if it was set up correctly

#

ik about the blue classes

#

but like whats the structure

fading lake
arctic moth
#

o

#

k

#

ill try that

fading lake
#

eagerly awaiting sirionblatt's essay

noble lantern
#

how have you survived without a main or java folder

Hey, I have a question!
I use IntelliJ to make a plugin and now I'm trying to make one using Spigot 1.18.1. The problem is, that somehow IntelliJ does not recognize it or something, because none of the Classes and methods can be used (like JavaPlugin or Player and so on), it just says that this does not exist.
Any help?

fading lake
arctic moth

noble lantern
#

imagine having to use build tools

fading lake
#

imagine

rich inlet
#

No buildtools and my SDK is Java 17

noble lantern
#

ive only ever used it for NMS, other than that my ide auto imports it from the repo

#

weird

#

invalidate caches?

young knoll
#

What are you depending on

#

Inb4 bootstrap jar

fading lake
#

spigot or spigot-api

rich inlet
#

spigot

fading lake
#

aight you need buildtools for that

solar plinth
#

Extract resources from unknown directory structure

rich inlet
#

but with spigot 1.17 it works

noble lantern
#

^

#

iirc spigot is the NMS jar and api is the actual api

#

i could be wrong

young knoll
#

Correct

fading lake
#

does anyone know off the top of their heads what the intarray is for on 1.8 PacketPlayOutEntityDestroy? It takes an int..., is that for multiple entity ids or something else?

arctic moth
#

btw would the path in plugin.yml be any different with the main and java

#

im assuming it would be the same

noble lantern
rich inlet
# noble lantern

Uhm I am not really that advanced in Plugin developing, what should I do with this?

noble lantern
#

just follows package path

noble lantern
fading lake
#

maven best

hoary pawn
#

how would i convert collection<players> to arraylist?

rich inlet
#

Currently not but I heard it is really useful

noble lantern
#

or

#

new ArrayList<>(Arrays.asList(thatCollection));

hoary pawn
#

ahh lol

fading lake
#

you could do it via iteration, but people who do that are psychopaths

Hello I have a problem with my plugin. So I want create one file for each arena if in the config the multi arena is allow. But when the file default.yml is created I want add a defaults config with a arena.yml files the ressources of the plugin. I have a Null pointer exeption why ? Can u help me plz...

My main class EBuild:
https://www.toptal.com/developers/hastebin/disuveroya.typescript

noble lantern
#

so you can pass a List of soemthough through it

rich inlet
#

Is there a way without maven? Just use spigot-api for the library?

noble lantern
#

gradle?

#

You know what

#

imma hook you up with something

#

its gonna save you life

#

File -> Settings

rich inlet
#

okay?

noble lantern
#

look for this plugin

#

and just remake your project, you can just put your old class files into that new project

fading lake
# hoary pawn feel kinda dumb know

dw I spent literally 5 mins yesterday being confused why the following was throwing an error, and ive been using java for 2 years
byte = 5 >>> 1

arctic moth
#

whats one dark theme lol

hoary pawn
#

lol

noble lantern
#

that plugin automtically import spigot-api in gradle or maven

noble lantern
rich inlet
#

Thats cool, ill try it, thanks

arctic moth
#

whats the difference

#

is it darker

#

lol

fading lake

what the fuck is that link

@noble lantern so with this plugin do I have to have the extern spigot library or should I just leave it?

would it be possible to code plugins / mods in python?

arctic moth
#

lol

hoary pawn
#

WHY NOT

hoary pawn
sharp saffron
#

ok thanks

rich inlet
noble lantern
rich inlet
#

oh ok

noble lantern
#

and then choose "Minecraft"

#

it will be on the right

#

and then just transfer all your class files to that new project

hoary pawn
noble lantern
#

and from now on use that plugin when you create then

noble lantern
#

you first need to convert the Collection of player to a List of Strings

#

Cause List<String> isnt List<Player>

hoary pawn
#

is there a way to do that without a loop?

noble lantern
#

you can use lambdas and use method referances (::)

#

thats about as short as you can get

hoary pawn
#

then i just need to learn da fuk that is

#

maybe it is better to use a loopå

noble lantern
#

idk if theres a built in way but thats how i always convert my Lists

arctic moth
#

i feel bad for anyone that joins this server lol

# rich inlet okay thanks!!

You can also just fill in jibberish and then edit the packages and main class yourself i do that because its naming is a little weird

arctic moth

rip people that dont have autoclickers

rich inlet
noble lantern
#

i dont like com.burchard36.plugin.Plugin as my package class which is what it does normally

#

fun fact

#

My IGN is buchard36, but i made a typo when signing up on spigotmc

#

so im buchard37 to the spigot community lmfao

getName?

hoary pawn

not sure if that was mc related

noble lantern

last week i tried out a class extending YamlConfiguration and i think im in love

so damn awesome to just this.getString

instead of having to referance a YamlConfiguration object

Iirc setTypeAndData

young knoll
#

Or null if you want

noble lantern
#

or just return players

#

^

#

Initialize
process
return

#

You should make a static getter in your main class to

getOnlinePlayerNames

#

why do i feel like thats a default method but ik its not

young knoll

It’s not

Bukkit.getOnlinePlayers is

ide assume probably some type of packet manipulation

hoary pawn

lol

arctic moth
#

how do you make entities hit faster

#

cuz if i have 0 max damage ticks

#

they kind of just hit slowly anyways

red sedge
young knoll
#

There’s a method for it in modern versions

red sedge
#

it was p.setCooldown

hoary pawn
noble lantern
#

^

#

fr

#

just use packets with reflection and machine code scripts

red sedge
#

thats no fun

#

just remake minecraft in machine code

hoary pawn
#

even better, just rewrite minecraft with the changes you want

noble lantern
#

i wanna make my own server jar so bad

but im so bad

:sadge:

hoary pawn

it cant be that hard can it?

no ones made one yet written from raw java with mc protocol

so, its kinda hard

not that hard

whats the spigot 1.8.9 maven import btw

noble lantern

1.8.9 is a client only version

arctic moth

which isnt possible to do iirc (flow enchants transfered to sword)

The most they could get from it is a small amount of xp with a grindstone

noble lantern

ah i forgot about grindstones

arctic moth
stone sinew

k

#

would group be spigotmc or bukkit lol

#

on the website its bukkit

Not sure on that. Might just have to go look at the pom

hoary pawn

uhmmhmmmm

it always fumbles me

i thought it was something usefull

im used to looking at the top for my error not near the bottom

red sedge

i hate that when getting an item air is null

like yeah it makes sense

but why

or how there can be null InventoryClickEvents

# glossy scroll Where is that function and what are you trying to do

Im trying to create a circle out of particles in the direction the player is looking in with a certain radius and distance from the player.
And I've been delving in the realm of matrices and such, then I found #rotateAroundNonUnitAxis, but instead of that Im now using #rotateAroundAxis(Vector, Angle)
But the issue is still there that it rotates around ~0,0,0 cause Im using the direction the player is looking in, gotta set it differently

Well that was my original idea, to have a line, take a point from it, create a normal vector and rotate it, while always taking the tip of the vector as a point to spawn a particle, yet that doesnt seem to work in any way.

Hi! How are you?

I want to know why im having the error "Unhandled exception: MalformedURLException" on the throws of my method? When im throwing a custom exception that extends "MalformedURLException"


**Method where error its shown**
  
  public void load(File file) throws LoadException {
    ClassLoader loader = URLClassLoader.newInstance(new URL[] { plugin.toURI().toURL() });
  }

Exception class:

public class LoadException extends MalformedURLException {

    public LoadException() { }

    public LoadException(String text) { super(text); }
}

Any ideas why happen?

glossy scroll
#

And put it into the wolfram player

zealous osprey
#

cause I was looking trough the sphagetti of it

glossy scroll
#

Idk why they use that notation for zenith and azimuth angles

#

Should be phi for zenith and theta for azimuth

zealous osprey
#

Well if I figure it out or not, thx for being so helpful <3

quiet ice
glossy scroll
#

You need to catch the MalformedURLException and throw your LoadException

quiet ice
#

This is because MalformedURLException does not extend RuntimeException, which is why you need to explicitly catch it

#

(or just pass the exception along with a throws)

sterile token
glossy scroll
#

I think they want their own exception to appear instead of MalformedURLException but i cant be sure haha

sterile token
quiet ice
#

Then you need a try-catch block

glossy scroll
sterile token
#

I want to use the throws and then when you use the library you try catch the method

quiet ice
# 
try {
abc
} catch (Exception e) {
     throw new MyException(e);
}
sterile token
#

Thats why i didnt use that

quiet ice
#

Always use the ctor that accepts an exception/a throwable. Do NOT invoke toString on the exception

glossy scroll
sterile token
#

So its not possible to extend an exception, to then using it with "thorws ExceptionClass"?

glossy scroll
#

correct

sterile token
#

Omg thats why i prefer cs

glossy scroll
#

Because the JVM doesnt know how to convert the exception to your type

#

Its a very simple OOP

sterile token
#

OOP?

glossy scroll
#

Object oriented programming

sterile token
#

Ahh ok

glossy scroll
#

You cannot convert from Class A to Class B without providing instructions

#

Unless Class B is super class A

sterile token
#

Are u sure there is no way to do that?

#

Like change an exception name?

glossy scroll
#

There is, we’ve told you

glossy scroll
sterile token
#

Because i want to throw that exception but with diff name

glossy scroll
#

Right, we literally told you

glossy scroll
sterile token
#

Yeah but i cant use try catch

glossy scroll
#

Yea you can?

sterile token
#

Because its a library

glossy scroll
#

try catch isnt a library?

#

Theyre keywords in the jdk

sterile token
#

In my library people should try catch the methods themselves

glossy scroll
#

They still will

#

Because youre throwing an exception

sterile token
#

The message you cant change it

quiet ice
#

and your exception does not extend RuntimeException

glossy scroll
#

You can still use “throws MyException”

sterile token
#

Because the same error occur

quiet ice
#

Your exception cannot extend RuntimeException if it extends MalformedURLException

glossy scroll
# 
public void myMethod() throws MyException {
try {
abc
} catch (Exception e) {
     throw new MyException(e);

@zealous osprey i got it working but geogebra is dumb so i just used mathematica again

#

it doesnt know how to interpret vector multiplication which gives a parametric curve

zealous osprey
#

So the maths provided from the link should work as intended?
If I may ask, since I am somewhat confused, im assuming that the angles define the vector which then creates a normal vector of length r, right?

#

So it's using pitch and yaw

#

But in radians

Hey folks, I'm looking to decrease the amount of NMS code in my plugins. The 1.17 and 1.18 posts mentioning opening PRs to add to the Bukkit API where one would currently need NMS. Are there situations where it definitely would not make sense to put things in the API, but rather keep them NMS only, or is everything welcome? Currently using NMS to spawn particles for only one player, spawn invisible magma cubes for only one player and to modify a player's GameProfile.

glossy scroll
#

Correct, so the azimuth angle will be the yaw and the zenith angle will be the pitch

#

if im not mistaken

#

just whatever pitch and yaw correlate to this

#

also be careful because minecraft's angles are slightly different from real world angles

#

AND that minecraft is Y-up, not Z-up

so you'll need to swap the Y and Z values in the functions provided

@zealous osprey if you need to know the cross product with respect to the zenith and azimuth angles, here you go

Hello guys, I'm looking for a way to disable the built-in vanilla night skipping mechanism (the message "1/2 players sleeping"). Does anyone know if this is possible?

btw what's t, Im assuming it's the change in time, but it cant be

glossy scroll
zealous osprey

#

t is "time"

#

really

#

its just the step size

#

so at each t you get one point

#

depending how many points you want, you have a different amount of ts and you increase t by increments

#

t goes from 0 to 2pi

#

if you want 12 equally distributed points

#

you would make a for loop

#

t increments by 1/6 pi each time

#

and you would do that 12 times

ignore the phi

I have a plugin for skipping night when not everyone is sleeping, only a percentage have to be in bed to skip. However when I change the time with the plugin it causes the day cycle to get stuck. This is code im using to set time, is there a different I should be doing this?

i have this class which i use with custom event:

# 
package com.aregcraft.customstevechaos.event;

import com.aregcraft.customstevechaos.CustomSteveChaos;
import lombok.NonNull;
import org.bukkit.Bukkit;
import org.bukkit.event.Event;
import org.bukkit.event.EventHandler;
import org.bukkit.event.HandlerList;
import org.bukkit.event.Listener;

import java.util.function.Consumer;

public class EventListener<T extends Event> {
    @NonNull private final Listener listener;

    private EventListener(@NonNull Consumer<T> handler) {
        listener = new Listener() {
            @EventHandler
            public void on(T event) {
                handler.accept(event);
            }
        };
    }

    public static <T extends Event> EventListener<T> create(@NonNull Consumer<T> handler) {
        return new EventListener<>(handler);
    }

    public void register() {
        Bukkit.getPluginManager().registerEvents(listener, CustomSteveChaos.getPlugin());
    }

    public void unregister() {
        HandlerList.unregisterAll(listener);
    }
}
