us of a

[quaint mantle]

um.

how do i compile something?

[tender shard]

by running javac

or the eclipse compiler

or by telling maven to do that for you

or gradle's java plugin

or intellij's build system

[quaint mantle]

well the maven task does not appear to work properly.

i just got this error.

[plucky pasture]

I am trying to get user data from the config.yml file, and I am loading it in a config class by passing the constructor a plugin object to the config class then calling getConfig(), but when I try to get the config from a commandexecutor class I get an error where the plugin has already been instantiated.

[quaint mantle]

i just used that thing to create a project and i created the project twice and it still does that.

for 1.19.4.

[orchid trout]

        database.fetchStats(uuid).thenAccept(stats -> {
            UserManager.addUser(uuid, stats);
        }).thenCompose(data -> database.storeUser(uuid, thisherehastobestatshelp).thenAccept(data -> {

        }));``` any way to use stats in the other lambda expression?

[chrome beacon]

Try recreating on spigot

[lost matrix]

You are not allowed to create instances of JavaPlugin

[tender shard]

report it to paper

[quaint mantle]

is it my code or paper?

[tender shard]

idk, I haven't seen your code, nor do I know what shitty things paper has again invented with their new plugin loading stuff

[plucky pasture]

how can I let them edit the plugin with the config yml file then?

[tender shard]

?paste the full stacktrace

https://papermc.io/downloads/paper

[remote swallow]

you use di not new MainClassName()

[quaint mantle]

the latest one for download.

[orchid trout]

this is spigotmc

[quaint mantle]

ok fine.

where do you download a spigot server?

[remote swallow]

you cant

run buildtools

[plucky pasture]

I created have tried creating the config in the main class then passing it to the other classes but when I call the main class it still has that same 2 plugin instance issue

[remote swallow]

?di

[undone axle]

Guide to dependency injection: https://www.spigotmc.org/wiki/using-dependency-injection/

[quaint mantle]

yeah this is why i never downloaded spigot and just used paper instead.

how do i use buildtools lol, ik it is kind of late to be asking this.

[undone axle]

https://www.spigotmc.org/wiki/buildtools/

[remote swallow]

use saveDefaultConfig on onEnable in ur main class, pass the main class instance and you can use getConfig

[remote swallow]

download the jar, create a new folder, drag the jar in, open cmd/powershell there run java -jar BuildTools.jar --rev 1.19.4

[quaint mantle]

wait

why does it say current: 1.19.3?

[remote swallow]

hasnt been updated yet

latest rev isnt updated in buildtools either

prob will be next buildtools update

[tender shard]

If paper version X exists, spigot version X exists since days

[quaint mantle]

ok.

[grizzled oasis]

meta.setMapView(view); works on older versions? like 1.12.2 or how can i make it work with it?

[plucky pasture]

Do i need to getConfig in the onEnable? also just pass the main class and call methods on it after?

or am I running getConfig in the other classes?

[quaint mantle]

hm, it appears to be taking some time.

[tender shard]

you pass the main instance to your other classes, as explained in "method #2" here: https://blog.jeff-media.com/getting-your-main-classes-instance-in-another-class/

[quaint mantle]

wait is it downloading the entire source code lol?

[tender shard]

yes

[tender shard]

yes

well

[round finch]

?id

[tender shard]

it downloads mojang's jar, then decompiles it, then applies the spigot changes

then compiles it again

basically that

[round finch]

java depency injection (this is for other class) tip

it needs the instance of the plugin class

ak main

[quaint mantle]

pain.

[dusky hinge]

Yep, it was.

[remote swallow]

di not id

[round finch]

i know typo

[dusky hinge]

and now I need to wait for them to fix it lol

[plucky pasture]

So I can just pass my main class that extends JavaPlugin to another class? I thought I was trying that last night and anytime I was using that object it had the 2 instance error

[quaint mantle]

what are you doing?

[tender shard]

you pass your main class' "instance"

not the class itself

[plucky pasture]

is the new Class(); syntax when trying to get the instance what is messing me up? I see right here I should be using the getInstance method is it different

[tender shard]

yes

[plucky pasture]

AHHH

ok thanks

[remote swallow]

yeah, you create a new instance

[tender shard]

new Class() creates a new INSTANCE of the class

you wanna use your existing instance

which is called "this" in your main class

[round finch]

di or static Main instance

[tender shard]

as I already said, here it's explained: https://blog.jeff-media.com/getting-your-main-classes-instance-in-another-class/

both DI and static getter

[plucky pasture]

yeah I saw it in that

[tender shard]

choose whatever you prefer

[quaint mantle]

just create a static variable and store your instance on the onEnable(); method being called and use a static getter to get the instance.

[tender shard]

if it's a public variable, it should be final, hence be set in the constructor already. But then it cannot be static, so pointless lol

[remote swallow]

di if you can is prefered, if not then the static getter

[round finch]

public static PluginClassNameHere instance;

@Override
public  void onEnable(){

instance = this;

}

this is 1 way of doing it

[tender shard]

and even if it's not public (has a getter), I wouldn't wait until onEnable() to store the instance, but rather directly in the init block

[quaint mantle]

why is the first letter of the variable name uppercase?

[tender shard]

yeah that is confusing

[remote swallow]

smh vollx

[tender shard]

Instance looks like it's a class

[round finch]

that ain't a real class name

LMAo

[mortal hare]

are java bean classes just a class reflection convention

?

[round finch]

but i agree with you guys

[tender shard]

it should be called "instance", not "Instance"

[round finch]

shet

typo

[quaint mantle]

i already said that.

[tender shard]

java beans are one of the most weird constructs I ever heard and never found any proper definition for what it's supposed to be. from what I know, it can be basically anything

[mortal hare]

?? As far I can see Java Bean classes are being used to with reflection to retrieve fields and methods by using the same naming conventions

for example you have a String field named employee

you create getter getEmployee() to retrieve that field

they literally look like structs in c/c++

[tender shard]

yeah but that's usually a "convention" for basically everything

[hazy parrot]

Bean should basically be object that encapsulates other objects

[tender shard]

but yeah here's the docs about what it's supposed to be https://www.oracle.com/java/technologies/javase/javabeans-spec.html

[quaint mantle]

speaking of c/c++, java is kind of annoying.

[tender shard]

I disagree and find the opposite is true

[hazy parrot]

And also must be seriazable or however is that spelled

[tender shard]

seriziazale

S8e

[quaint mantle]

you have to declare and define your methods in the same file in the case of java, while for c/c++, you can just declare the method name for a class member and define it in another file, much easier to manage code structure.

[mortal hare]

I cant believe that they've made an 100 page spec about a class convention

[quaint mantle]

i find it really annoying to have my file sizes just be all over the place.

oh.

but you still have to define it all in the same file though, dont you?

[hazy parrot]

there is no real declaration of method in java as in cpp. Unless it's interface you always inline implementation

[tender shard]

I wouldn#t see any reason why one would want to split the code. Like, MyClass1.java, MyClass2.java and both contain half the code of that class? huh

[tender shard]

or an abstract method

[quaint mantle]

its much easier to manage.

[tender shard]

or a native method

[hazy parrot]

Yeah that too

[quaint mantle]

i find that kind of annoying.

[hazy parrot]

But you inline impl in most cases

[mortal hare]

I mean JavaBean class looks like the struct in Java or Record

but with the same naming conventions

to support reflection

to all sorts of data

headers do not split code

in headers you define like in interfaces

in cpp files you declare the implementation

wdym you cant define a header method

well yes

you cant include the same function declaration twice

[hazy parrot]

What is even header method lol

[mortal hare]

if that's what you meant by it

[tender shard]

yeah but having a separate header file wouldnt even make their implementation file smaller as it ofc would also have to tell again "for which method" every impl is for lol

[mortal hare]

but for that we have ifn define guards

[tender shard]

so I still don't understand how splitting it up into different files would have ANY benefit

[hazy parrot]

Method definition

[mortal hare]

you can swap implementations

[tender shard]

that's what interfaces are for

[mortal hare]

headers are equivalent but not identical to interfaces practically in c/cpp

the main reason to use headers is that you can provide the client the header file, and nothing more, and he can use shared library (like .dll or .so) to switch the implementations without recompiling the code

so basically the compiler just compiles the header file with client code and links the implementation, but at runtime, client can swap the implementations by switching files

[tender shard]

you could easily just share your interfaces in a .jar, and the implementation in another. e.g. bukkit vs craftbukkit

[mortal hare]

yea but you need to recompile your bytecode

while with headers you dont need to recompile the client at all

if you only change the implementation you only need to recompile the .dll or .so file

[tender shard]

or in this case, only recompile the craftbukkit .jar

[mortal hare]

well you can do it in java aswell with reflections i guess, because bukkit api uses classloaders to load plugins

thus you can access bukkit implementation by only accessing interfaces from maven repo api

very disappointing to find out the actual name is so boring

[round finch]

can java lambda sort by smaller or bigger number?

[ivory sleet]

i mean ye

[tender shard]

wdym? you mean whether you can write a Comparator<MyCustomObject> using a lambda? If so, sure

[chrome beacon]

?nocode

[undone axle]

It’s hard to answer a programming question without code
Oh no! You ran into a problem. But no worries, people are willing to help, but first they need to see your code. This is because otherwise, they would be providing help based on guesses instead of concrete knowledge. Whether it be a compile error, runtime error, or an unexpected output, I'm sure that if you were to provide code, you'd receive a quick solution.

[round finch]

i honestly got no clue

i havn't used it before

[tender shard]

public class MyCustomClass {
    private int value;
    public int getValue() {
        return value;
    }
}

now you can use a lambda:

    public static void main(String[] args) {
        List<MyCustomClass> myList = new ArrayList<>();
        myList.sort((o1, o2) -> Integer.compare(o1.getValue(), o2.getValue()));
    }

or even a method reference:

myList.sort(Comparator.comparing(MyCustomClass::getValue));

[round finch]

Integer.compare(o1.getValue(), o2.getValue()));
cool!

that is pretty neat

you gotta remap your .jar

[regal scaffold]

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

I'm using nms on 100 other things

Just this 1 is giving an error

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

[tender shard]

idk how remapping works in gradle, but you're definitely not doing it properly, otherwise the class "nms...Pig" wouldnt aven appear in your source code

it would be EntityPig instead

how did you run gradle? shadowJar?

or build?

rn you set the remap plugin to run on shadowJar, so you gotta use shadowJar to compile

[chrome beacon]

Repo username and pass 😳

[tender shard]

lol

who the heck embeds the password in the build script

[quiet ice]

Hopefully it is read-only

(I have no idea how github maven repos work tbh)

[tawny remnant]

how can I save and load a HashMap<Integer, ServerPlayer> from a config file?

[tender shard]

wtf

you can't

nms players are not serializable

well at least not in the usual way

I doubt that reading the player data from their .dat file is what you want to do

[tawny remnant]

so how can i do it

[tender shard]

@regal scaffold you still haven't changed your github package repo password

[tender shard]

?xy

[undone axle]

http://xyproblem.info/

[plucky pasture]

Should I also create instances of other classes for these plugins? Or can I call other classes than main with a new instance of that class

[quaint mantle]

My maven profile for changing the out dir isnt working it just wont build there

[tender shard]

?paste your pom

Can someone dm a backslot plugin please

[tender shard]

no

[quaint mantle]

https://pastebin.com/yFMQd3Jv

There

[tender shard]

looks good. did you even enable the profile?

[tawny remnant]

i got it now

Is there any way to save a HashMap of Integer and ServerPlayer to config.yml?

[tender shard]

still, no

you asked that 2 minutes ago, remember?

[round finch]

Not Sure what you're talking about exactly

[tender shard]

?xy

[undone axle]

http://xyproblem.info/

[round finch]

do you want to access the other classes from other plugins?

[tawny remnant]

sir i read that already

[tender shard]

and then you asked the same question again

instead of explaining what you're actually trying to do

[granite owl]

i think ill program a backpack plugin in which u can store filled backpacks in backpacks🤔

[regal scaffold]

Oh lol

The original dev

Is dumb

[tawny remnant]

Im trying to save a hashmap of Integer and ServerPlayer to config file

[tender shard]

and why

[regal scaffold]

Considering there is literally secret keys in gh

[tawny remnant]

so they dont disappear

[round finch]

@tawny remnant question what you want?
cus you could just use UUID in a list

[tender shard]

Map<Integer,ServerPlayer> myMap = new HashMap<>();
getConfig().set("myUselessMap", myMap);

ez

[regal scaffold]

@tender shard It's not even my credentials how do I change them

[tender shard]

totally useless though

[chrome beacon]

Watch people ban themselves

[tender shard]

idk lol

never used github packages

[granite owl]

exactly, natural selection

either that or the server dies

[quaint mantle]

Just enabled it and still not workin

[tawny remnant]

This will save the whole map correct?

[tender shard]

sure

[tender shard]

?paste the ENTIRE maven output

[undone axle]

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

[quaint mantle]

(Also yes i did reload maven)

[granite owl]

isnt a map serializable?

[tawny remnant]

sure meaning sarcasm or "yes"?

[tender shard]

it means yes

[tawny remnant]

okay thank you

[tender shard]

it won't be of any use though

[quaint mantle]

There is no output

Thats the concerning part

[tawny remnant]

cus im not loading it am i

[tender shard]

how did you even compile it then?

[quaint mantle]

I pressed the build button

[tender shard]

which one?

[quaint mantle]

Build > Build Project

At the top

[tender shard]

that's not maven

you have to use maven to compile

Upper right, maven tab -> Lifecycle -> package (double click)

[vocal cloud]

ctrl + ctrl -> mvn package

[granite owl]

btw is it possible to have different jetbrains ides linked to different git accounts? i use intellij for private projects but i need to use clion for a university project xD

and in order to not get kicked out i need to commit using my university mail

but it seems they use the same global settings

[vocal cloud]

https://www.jetbrains.com/help/idea/github.html#register-account

[quaint mantle]

Just built and tried running and it errored out
https://pastebin.com/3cFfC8A0

Not code related from looks of it

[tender shard]

go complain at paper

[vocal cloud]

Caused by: java.lang.IllegalArgumentException: File 'plugins\SynMC-1.0-SNAPSHOT.jar' is not a valid plugin file, cannot load a plugin from it!

Gotta read your errors lol

[tender shard]

that's a paper bug

[quaint mantle]

I dont get how its not a valid plugin file

[tender shard]

it's a paper bug

[quaint mantle]

Ah

[vocal cloud]

Ask on le paper

[tender shard]

someone earlier had the same issue

then paper confirmed their shitty new plugin loader is shitty

[quaint mantle]

🥲

[tender shard]

at least that's what they reported back

[quaint mantle]

There possibly an issue with my directories?

It goes src > main > java > com.kunosyn.synmc > SynMC.java

[granite owl]

recursive answers require altered conditions to have a definitive end

[tender shard]

no, otherwise it would complain about missing main class or missing plugin.yml

it's a paper bug

?paperbug

[vocal cloud]

?paper

[granite owl]

its a spigot bug

🐒

[quaint mantle]

I just wanna know how to fix it tbh lmao

It was working perfectly fine before i switched to maven as a dep manager

[tender shard]

yes, because spigot is known to throw custom plugin loading logic into classes called io-papermc.paper" lol

[granite owl]

no that the bot is ded

[tender shard]

wait until paper fixed their plugin loader

[granite owl]

or stop using paper

[tender shard]

yeah just run spigot

[granite owl]

i found 2 functions i wanted to use that paper has that spigot doesnt

and i worked around them

other than that idk what the advantage is supposed to be

the "advanced" api has like 10 functions more xD

[quaint mantle]

Idk how to run a server using just spigot and not paper

[granite owl]

?

[quaint mantle]

Like as in i have a testing server

Stored locally

[granite owl]

paper is a spigot fork wym u dont know how to run a spigot server

[quaint mantle]

I mean as in idk how to stop using paper

Like how I would setup a test server with spigot

[granite owl]

like u replace the jar?

im baffled

[tender shard]

Does your plugin’s .jar even contain a plugin.yml file?

[granite owl]

are u asking how to use the buildtools?

[granite owl]

doesnt the plugin.yml need to be in the resources directory?

[tender shard]

DM me your .jar file, then I can check whether its correct. However if it werent, papers error message should look different

Yes

[granite owl]

to be included in the jar

maybe its not

in his plugin

[quaint mantle]

It should unless it was excluded by the dep managers build

[tender shard]

If its missing from the jar, paper should say „missing plugin.yml“

Instead of the error you got

At least thats how spigot does it and how paper used to do it

[granite owl]

i actually had problems with the plugin.yml so i manually added it to the jar to figure what went wrong. then i figured it wasnt included in the first place cause i didnt put it into the resources dir

🤣

[quaint mantle]

Ill send it to u

[eternal night]

damn that is crazy too, but how do you set no ai on entities in 1.8 ?

[tender shard]

Slughorn, ofc

[vocal cloud]

Damn that's crazy but where do I find spigot for beta 1.2

[eternal night]

but yea, the error is no plugin.yml

the message is a bit bleh, but since paper has paper-plugin.yml as well

its a bit more complex than "Missing plugin.yml"

I'll bring it up for fixing tho 👍

[vocal cloud]

if(both missing) error

[tender shard]

It could say „missing plugin.yml or paper-plugin.yml“

[eternal night]

yea both are missing, the error just needs to be more descriptive

[granite owl]

i get ptsd from those bot comments

[quaint mantle]

Sent the jar to u

[vocal cloud]

just need to write a simple webapp that checks for it

[tender shard]

yeah you don't have any plugin.yml

it belongs into src/main/resources/

[granite owl]

xD

[tender shard]

Didnt you say you added it manually?

Then why is it still not there lol

[quaint mantle]

It wasnt in the resources dir that was the issue

it was just in the proj dir

[granite owl]

i daid

i said

i did it once

[tender shard]

Someone earlier had the same error message and claimed the paper guys said its a paper buf

Bug

So apparently the bug just is the bad error msg

Idk loo

Lol*

[granite owl]

so i presume his plugin worked before maven cause there was no resources dir

🤔

[quaint mantle]

Yea

[tender shard]

Probably

[quaint mantle]

Paper did say theres an issue tho

They said their error should be more descriptivie

[tender shard]

Which is true, the current message is useless

[quaint mantle]

descriptive however u spell that

They said its an extremely common issue

i have a problem with multiverse core it load the flat map but not the buildings which i have built on the map whats happening ?

[tender shard]

#help-server

[granite owl]

throw new NullPointerException("u have error");

[quaint mantle]

Thats exactly why

[granite owl]

just put the plugin.yml there

[quaint mantle]

I downloaded 1.19.4 from the spigot site directly and set my own dependency using a module

I did

Its all g now

[tender shard]

You cannot download spigot from the spigot website

[quaint mantle]

Then how did i do it lol

[tender shard]

You can only download it ilegally from illegal websites

[granite owl]

u downloaded it from another site

and id be careful with viruses

[quaint mantle]

Oh 🤷 i just followed a yt tutorial

[eternal night]

[quaint mantle]

Yea i checked the jar n all that

And scanned the download

It was all good

[tender shard]

Wouldnt surprise me if „illegal bukkit download website“ would add shady stuff to the jars

[granite owl]

lol the bot deleted my msg

[quaint mantle]

https://hub.spigotmc.org/nexus/content/repositories/snapshots/org/spigotmc/spigot-api/

[tender shard]

Well i could easily write a jar that doesnt get detected by any website but still sends me all your home folder sooo uh

[tender shard]

But that is just the API

not the actual server software

[quaint mantle]

Thats exactly where i downloaded it from

The jar file

For the dep

[tender shard]

Yeah but you needed NMS

[quaint mantle]

Mhm

[tender shard]

So you needed the actual jar

[quaint mantle]

Which is why i switched to maven

Yea

[tender shard]

Yeah fair

I thought you said you downloaded spigot, not spigot apu

Api*

[quaint mantle]

Oh yeah naw just the api file

Then when to like modules and added it as a dependency

[granite owl]

even worse, since its a server u need to let it trough ur firewall

so

u wouldnt even notice it

cause i mean its a server xD

[quaint mantle]

Is there any way i can configure my inellij so when i press run it just runs the bat file that starts the server for me?

So i dont gotta like go to file explorer n all that

[granite owl]

why

[echo basalt]

you'd probably be configuring gradle / maven instead

[quaint mantle]

Ah

[granite owl]

am i the only one just using /reload?

xD

[echo basalt]

yes, ew

[granite owl]

🤔

[tender shard]

you can add another maven profile with the maven-exec-plugin

[quaint mantle]

Ah alright

Do u happen to have an article on that as well? lmao

[tender shard]

here, I wrote you an unfinished blog post. "running the server" is the same thing as earlier, just enable the profile https://blog.jeff-media.com/start-a-test-server-using-maven/

oh wait

that's missing the maven-exec part

[quaint mantle]

Damn

[tender shard]

now I remember why I didnt publish it yet

[quaint mantle]

Lol

or gradle java toolchains

[tender shard]

depends

[mortal hare]

ik they do different things

like toolchains download jdk builds and etc

[tender shard]

do you wanna use the same JDK as the one you set your target/source to? if so, toolchains

[quaint mantle]

Plugin 'org.codehaus.mojo:exec-maven-plugin:3.0.0' not found

[tender shard]

reload maven

[quaint mantle]

Same thing

Is it supposed to be a profile?

Instead of a plugin

[tender shard]

it's supposed to be a plugin declared in a profile

[mortal hare]

wdym by "do you wanna use the same JDK as the one you set your target/source to?" are you saying i should combine them

what's the purpose of combining compatibility fields

with toolchains

[tender shard]

can't really be, it's on maven central:

[mortal hare]

i cant see any benefits when toolchains literally download builds of jdk to compile

unless you want to deploy it on older versions of jre

[tender shard]

well I for example use jdk 17 to compile, but with a source/target set to java 8

[quiet ice]

Some JDKs don't support the release flags

[tender shard]

that way I can access dependencies that use java 17, but still make my stuff work on java 8

[quiet ice]

Or have other whacky behaviour

[tender shard]

gradle toolchains do not allow this

[mortal hare]

how tf does that work

you have java 17 class bytecode

[tender shard]

no, I have java 8 class bytecode

that's what the source/target thing is for

[mortal hare]

do you mean when you shade them?

[tender shard]

no, I mean when accessing other plugins

[orchid gazelle]

Hello

[tender shard]

e.g. imagine I have worldedit as optional dependency. imagine worldedit requires java 17. That's why I need java 17 to compile, otherwise it would complain "cannot access class com.worldedit.whatever"

I still want my stuff to work on java 8. So I set target/source to java 8

that works just fine

[mortal hare]

i kinda get it but kinda not

if depedency is a jar file

lets say

its compiled to bytecode .class files

[quaint mantle]

Set it up and it errored out

Error: Unable to access jarfile server.jar

[mortal hare]

with jdk 17

[orchid gazelle]

Maven ftw

[tender shard]

then change your start.sh file to use the proper server.jar name

[mortal hare]

and you're compiling your plugin with the same ver of jdk

what happens when you access jar plugin files

which is compiled with older jdk

[tender shard]

jdk 17 can access java 17 .jars but still compile your own code for java 8

[tender shard]

then everything works fine because java is backwards compatible

[mortal hare]

lets say i compile with java 8

[orchid gazelle]

Okay hi guys so I want to know in which 45deg direction the player is looking and turn that by 90 or -90 degrees to get left/right of it, how would I do that?

[mortal hare]

and i access jdk 17 compiled plugin

class instances

[orchid gazelle]

Take the direction, ignore y, somehow clamp to 45deg?

[quiet ice]

Asking again since other people are on right now:
What is the best way of adding your own dependencies that are generated at compile-time? Preferably without using maven - but sources MUST be attached to the dependency (using a file collection with the sources and the "real" jar does not work as-is)

Implementing SelfResolvingDependencyInternal on my custom AbstractDependency instance doesn't seem to do the trick when running ./gradlew dependencies

[tender shard]

can't you justt add/remove 90 from the location's yaw?

[quaint mantle]

The thing is it only does that when running in intellij

[orchid gazelle]

Well I wanna know in which direction I gotta move my coordinate

When hitting left/right in my ui, it should move the coordinate on the actual left/right relative to the player

[tender shard]

ah ok. Add this to your exec-amven-plugin's <configuration> (where you also got the <executable> part)

<workingDirectory>/Users/mfnalex/mctest</workingDirectory>

like this

[mortal hare]

is there any way to make optional toolchains?

[quaint mantle]

Alr

[mortal hare]

like if there's targetcompatibility version

of jdk

then jump to the toolchain declaration as a fallback

[orchid gazelle]

I mean then I do know the angle, but not in which direction I gotta move

So basicly I need translation between coordinates and rotation

[tender shard]

hm maybe you need some sinus/cosinus/etc math shit for this

[quaint mantle]

Works ty

[orchid gazelle]

Im fine with that

I love maths

But well.. I don't know how that would be useful here

[tender shard]

https://bukkit.org/threads/getting-a-block-to-a-players-right-left.180411/#post-1889660

[orchid gazelle]

Ty imma take a look at it tomorrow for sure, but it does not clamp to 45degs

[quaint mantle]

How could I get a recipe's matrix? Basically Im trynna make a listener so people cant use my plugins custom ingot "Enderite" to like craft something like anything that you would craft with normal iron since its just an iron ingot with metadata

[tender shard]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/inventory/ShapedRecipe.html#getShape()

that returns the string as it's defined, e.g. {{"#"},{"#"}} or

#
#

for sticks, where # is wood planks

however are there actually any vanilla recipes that do NOT use material choices?

because materialchoices also work with metadata

or am I confusing sth

[worldly ingot]

You're way better off comparing the recipe's key

[tender shard]

wdym with comparing the key?

[worldly ingot]

ShapedRecipe#getKey()

[tender shard]

how would that help?

[worldly ingot]

Oh they want to disallow the use of a custom item in other recipes

Disregard

[quaint mantle]

I could just use the recipe ingredient map

[tender shard]

I thought the opposite was true, I thought they wanted to allow it lol

i misread

[quaint mantle]

There any better way of doing that? Other than using an event to set result to air under circumstances?

[worldly ingot]

Yeah I was going to suggest the ingredient map as well. The shape won't matter

[tender shard]

just cancel every craft prepare event whenever one of your custom items is inside the matrix

[worldly ingot]

Nah, recipe prepare event is your only bet there

[quaint mantle]

But you're able to craft things with the custom ingredient

I just dont want them persay using enderite bars to craft an iron pickaxe

[tender shard]

then just check whether the matrix contains your custom item, and if yes, if the recipe that's being completed is NOT your custom recipe, then cancel it

[mortal hare]

hmm i didnt knew you can embed cpp code inside jvm

JNI allows you to write c/cpp code

and execute it through jvm

imagine the potential for large scale networks

for this

[tender shard]

ofc, native methods

and stuff

[mortal hare]

i wonder if hypixel utilizes this to balance network load

[worldly ingot]

It really doesn't

[tender shard]

that's e.g. how getClass() works

[worldly ingot]

Its primary use is to get access to some functionality at a lower level than Java

[mortal hare]

i mean there's not much potential since most of the minecraft code is in java

[worldly ingot]

e.g. some OS-exclusive API

[mortal hare]

but still

[worldly ingot]

Trust me. It's not as useful as you might think to Minecraft servers lol

[quiet ice]

Before you get excited: JNI may not be with us for long

The JVM devs plan to eventually lock down JNI

[vocal cloud]

Isn't it because they're adding the ability to interface directly with c/c++ libs

https://openjdk.org/projects/panama/

[wet breach]

it does more then just this

however it has a downside though

the downside is that it is only handy for some heavy weight code stuff that can be done better in CPP or long running code because context switching kills the performance gains/benefits

[wet breach]

there is more then JNI. JNI is just one part of a suite of utilities

JNA and JNR exist

[wet breach]

it isn't the JVM that executes the native code fyi, but it should make sense why you are able to use such things with Java given the JVM is built from c/cpp 😉

[quaint mantle]

Is there any way to add multiple recipes at once?

Instead of individual addRecipe?

[young knoll]

No, you’ll have to call addRecipe for each

[quaint mantle]

Damn

[young knoll]

If you want to add a bunch quickly, throw them in a collection of some kind and loop over it

[mortal hare]

but JNA will exist though right?

[livid dove]

I know this sounds stupid but surely if ur doing it every 45 degrees.

Get ur current angle.

Divide by 45 and get the remainder.

If the remainder is less than 22.5, it's the 45 degrees closest to the left, if it's more, it's it's 45 degrees to the right.

Snap to the appropriate 45 degrees and then rotate 90 degrees in the way you need

• other way around

Bungeecoord,

I'm trying to send a player to another server using the bungeecoordapi. The error messages above are precicely what i'm having trouble with.

[quaint mantle]

So I wanna make custom pickaxes so as a basis for the custom stuff I make it wooden then modify its meta, i was wondering if theres a way to make a wooden pickaxe as efficient as a netherite pickaxe or like just generally change efficiency of pickaxes?

Like through use of nbt tags or so on

[wary topaz]

you can probably modify packets and increase the mining rate taht way

as I know that is how hypixel skyblock does it

[quaint mantle]

I havent been able to find anything on modifying packets but seen it mentioned on the spigot website

[echo basalt]

ehh

it's a pain

[mortal hare]

tbh im surprised is how easy to make JNI compatible shared libraries

compared to how pain in the ass is to setup php extensions

[echo basalt]

you can send mining fatigue packets and do some funky stuff for arm swings

and then emulate the block crack packets

to basically make custom block breaking

[wary topaz]

oh hi illusion youre good with apis could you help me with my bungeecoord problom?

[quaint mantle]

How do I include craftbukkit as a maven dep

I wanna be able to run ItemStack.asNMSCopy but I think its a craft bukkit thing

use this if you want to access NMS or craft bukkit classes

[rigid otter]

Can we store custom data in an item in 1.12.2? I don't see PersistentDataContainer there.

[young knoll]

Not with the api

[rigid otter]

So, how?

[young knoll]

NMS

Add NBT data to the items

Or use NBTApi

[rigid otter]

Ohh I see, the keyword is NBT, thank you!

[full saddle]

I tried to set the item in hoppers when hoppers move items by doing either removeItem or setItem, but neither of them affected the hopper despite being executed and no errors showed, what could be the issue?
Code of the listenner that has this issue:

@SuppressWarnings("depracation")
@EventHandler
public static void HopperEvent(InventoryMoveItemEvent e){
  if(e.getSource().getType() == InventoryType.HOPPER || e.getDestination().getType() == InventoryType.HOPPER){
  e.setCancelled(true);
  int empty = 0;
  int limit = 10;
  int loop = e.getSource().getSize();
  while(empty < loop && limit > 0){
    ItemStack item;
    int amount;
    if(e.getSource().getItem(empty) != null){
      item = e.getSource().getItem(empty).clone();
      if(item.getAmount() > limit){
        amount = item.getAmount();
        item.setAmount(limit);
        e.getDestination().addItem(item);
        item.setAmount((amount-limit));
        limit = 0;
        
        } else{
            limit = limit - item.getAmount();
            e.getDestination().addItem(item);
            item = new ItemStack(Material.AIR, 1);
            }
       e.getSource().setItem(empty, item);
    } else{
        empty++;
        }
   }
}

[orchid gazelle]

Well I want all 45deg rotations to be possible, not only check for slight-left/slight-right

[rigid otter]

Can I remove all Mojang provided commands?

[rigid otter]

How does this work?

PluginManager#registerEvent(Class<? extends Event> event, Listener listener, EventPriority priority, EventExecutor executor, Plugin plugin);

What about Listener and EventExecutor?

[undone axle]

https://blog.jeff-media.com/nms-use-mojang-mappings-for-your-spigot-plugins/

[abstract sorrel]

have you registered the event in your main class?

ok

[wet breach]

Not sure why you have to check for player

This assumes that something that isnt a player could drag items in an inventory

Maybe gettype is only set if you hold shift?

[ornate patio]

Is it possible in any way for a user to be in survival mode but have access to the creative inventory

[wet breach]

No

But you could simulate it

[ornate patio]

How so

I guess i could create a GUI

to replicate it

[wet breach]

The look of the inventory is controlled by the client when it knows its in creative. And both client and server behave differently in regards to creative. So it isnt possible to use some kind of hack to have a player in survival mode but have access to the creative mode inventory. So as you said you would have to create some kind of gui to simulate it.

Interesting. But isnt your matrix like 2 slots away?

If so i dont see that being a particular issue

[ornate patio]

Yeah I thought so. just wanted to make sure it wasn't possible before i commited to the gui

[remote swallow]

its registerEvents for a class, thats registering a new e vent

[brave shadow]

What means this Error? Pls Help!

[pulsar flicker]

gotta show the entire error message. Usually the type of error is displayed at the top of the error message, not where it says the location of the error.

[brave shadow]

this?

[sullen canyon]

show the code

[quasi flint]

#help-server

[pulsar flicker]

That is not the entire error message. But I'd assume from what you've sent so far that you are trying to do something async that you maybe shouldn't. Can't really say as we don't have any idea on what your code looks like or where in the code you are experiencing the problem.

[brave shadow]

ok but thx you!

[misty ingot]

so yk how we have persistent data containers for players and items
do we have anything like that for mobs?

[remote swallow]

if you can see it on this list it does

[fluid river]

Entity is always PD holder

same as ItemMeta and Chunk

[misty ingot]

i zee

[green prism]

Do you think it's better to customize the plugin language based on the specific player's locale or to create a universal language that is the same for everyone?

[rotund ravine]

I just go with english

Or make some locale files

[green prism]

So in your opinion, should I avoid using per-player locale?

[remote swallow]

i'd say it depends on how much your plugn interacts with the player

[rotund ravine]

Depends on what you ^

[green prism]

tysm

[fluid river]

well for russian servers you only need ru_RU

but for europe and USA just english would be fine

[remote swallow]

make sure to always include lolcat

[fluid river]

you can just create locale folder with en_EN.yml, ru_RU.yml and so on, and when sending a message just use Player#getLocale to determine which file should be used

if there is no file for the locale use default servers language stated in config.yml for example

like default-language: en_EN

[remote swallow]

^^

[fluid river]

i went to smoke for a bit

now i want to make own library for random shit

like the one i already made for namespaced keys

public static final NamespacedKey key(String s) {
    return new NamespacedKey(instance, s);
}

[flint coyote]

Impressive lib lol

[fluid river]

import static me.carefall.lib.Key.key;
...
void method(Object... args) {
    // code    
    key("myKey");
    // code
}```

why not

relatively new feature

[flint coyote]

There's nothing wrong with it. Saves you some extra characters on usage

Also Key.key("myKey"); would look weird

[fluid river]

yup

[remote swallow]

NamespacedKey.fromString("coolKey:KEY") be like

[fluid river]

sheeit

how does this method get your instance tho

[remote swallow]

it doesnt

[fluid river]

can anybody provide the code

oh

?stash

[undone axle]

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

[remote swallow]

you either use that orNamespacedKey.fromString("coolKey:KEY", instance)

[fluid river]

isn't the thing deprecated without instance

i forgor how is the pattern called

[flint coyote]

Not according to documentation

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/NamespacedKey.html

[fluid river]

deprecated

[flint coyote]

That's not the fromString method tho

[fluid river]

oh

still

looks kinda weird

why arent they tagged as deprecated

cuz they might be for internal use too

[flint coyote]

I dunno

[fluid river]

what to code

i have nothin' to do atm

[chrome beacon]

This is for internal use

[flint coyote]

I got way too much to do to complete my current project. Both ain't cool

[fluid river]

..

the ony which constructs you an instance to your exact purpose

like one instance for working with Items and one for Entities

Is that a Factory?

yeah ig

[flint coyote]

Yes a factory creates an instance of an interface

Obviously that interface should have implementations but in a factory you just put parameters and get any implementation

[fluid river]

public class PDCBuilderFactory {
    public static PDCBuilder newInstance(Object holder) {
        if (holder instanceof ItemStack) return new ItemStackPDCBuilder();
        if (holder instanceof PersistentDataHolder) return new HolderPDCBuilder();
        return null;
    }
}

public abstract class PDCBuilder {

}

public class ItemStackPDCBuilder extends PDCBuilder {

}

public class HolderPDCBuilder extends PDCBuilder {

}

like this

where both itemstack and holder builders are extending PDCBuilder

[flint coyote]

The factory itself could be instantiated. Although it doesn't have to be if there's only one

But besides that, yes

[fluid river]

should that be interface only tho

abstract classes are not under factory pattern?

[flint coyote]

You want a factory for a builder?

[fluid river]

i want factory for builders xD

i mean builders are empty

[flint coyote]

That would only make sense if you cache those builders because a builder is usually not created to be used a single time

[fluid river]

hmm

idk

arent u creating a new StringBuilder to be used just once

[flint coyote]

If you create an instance of a builder to create a single object using the builder then your factory might aswell create that single object for you instead

[flint coyote]

I sometimes reuse those, too

[fluid river]

but still

[flint coyote]

Well the reason for a string builder is that constructing a string from multiple strings is more expensive than using a single object builder

For other objects that's not the case

[fluid river]

and for example if you have an ItemStack builder

which would need PDC, name, lore and other stuff

cant u just inst a builder from material

and then use .method().method().toItemStack() to make it as you want it

and then forget about the builder

that's just turning this long process into like one-liner

and instead of working with meta yourself you just let the builder do everyting under the hood for you

[flint coyote]

I usually create a single function that takes those parameters (or null) for that but if you like the builder pattern that much you can obviously take that route, too

Or you swap to kotlin and never need a builder for such things ever again 😛

[fluid river]

i mean that's just the thing i once saw in somebody's code

they had an ItemStackBuilder

[flint coyote]

There's nothing wrong with it. But why would you want to create a Factory for all those Builders instead of just instantiating them on demand?

[fluid river]

which basically had the methods like .withName(String).withLore(StringList).withPDC(key, Type, Value).toItemStack();

if you have a pdc support, then you need one builder for Entity and Chunk and one builder for ItemStack

cuz sadly ItemStack is not PD holder

only the ItemMeta is

i mean you can just have one builder where you pass Entity, Chunk and ItemMeta

but then you need to get the meta and set it back after your builder finished working

[flint coyote]

But if you create those Builders as seperate classes anyway then instead of Factory.newInstance(ITEMSTACK);. You could just go with new ItemStackPDCBuilder(); aswell

[fluid river]

yeah the enum was cringe for that purpose

i have another idea

[fluid river]

.

like this

you can pass like anything

but if you passed an item you get itemstack builder

and if entity or chunk you get just pdc holder builder

and for everything else you get null hehe

this looks super cringe i know

[flint coyote]

It would make sense but only if you don't know what you are working with - because otherwise you can still just call new WhateverBuilder() anyway.

[fluid river]

lol the "Builder Factory" pattern is actually a real thing

[flint coyote]

If you do know what you are working with it's just getting the same builder with extra steps

[fluid river]

i guess i just had to google it

thanks anyways lol

[flint coyote]

I mean you can do it and I wouldn't consider it bad practice. I just don't think it's reasonable^^

[fluid river]

yeah probably

i want to find like any case when Builder Factory might be useful in bukkit

[quaint mantle]

Hello

[flint coyote]

For nms custom entities

[fluid river]

hi

[flint coyote]

oh bukkit, then no xD

[fluid river]

what about multi-version support

when you just return the correct instance of something depending on the mc version target plugin has

[flint coyote]

The version of the plugin won't help you unless the factory ain't part of the plugin. But it would make sense for the server version when things significantly changed

[fluid river]

i guess you fuck up patterns and just send the version of your plugin as a string to the library

and setup a static util class with one inst() method lol

[flint coyote]

Yeah that sounds reasonable. Just keep in mind that for completely new features you'd still run into an issue.

[fluid river]

yup

[flint coyote]

Like a version where itemmetas don't have a pdc, your builder would still have a pdc method that would result in an error

[fluid river]

you just set up the corners of your library

like the lowest supported and highest supported versions

and you loop through all javadocs of all versions

finding what can be wrong if you run X on version Y

what a mess

[flint coyote]

Sounds like a lot of effort but yeah, that way you could even fix the builder implementation

[fluid river]

💩

i mean someday i might try

but meh

too much work

gonna smoke brb

[tender shard]

smoking is healthy

[fluid river]

cool

[tender shard]

i'll join

[fluid river]

send a picture

if your husband wouldn't kill me for that

[flint coyote]

It would have a usecase atleast.
But your builders would still have to check whether the current version supports whatever thing you wanna add (like a pdc). And the in the function just skip the "add pdc" part

[fluid river]

how is he doing tho, you said he had a medical operation

i guess that's not for help-dev tho

tbh it's not really very good rated

[eternal oxide]

yeah thats critics

they are paid to hate on it because its not woke

[tender shard]

yeah idk just watch it yourself, I found it extremely boring and childish and counted down the minutes until it would hopefully end again

and I even had a few beers before, it was still boring

[eternal oxide]

yeah I can imagine that happening if you've not played the games

[tender shard]

lol

[tribal quarry]

why? pay to hate on a movie like that?

[eternal oxide]

I doubt it deserved such a high audience score.

[tribal quarry]

well its not bad, & not too good

[tender shard]

it's not the worst movie ever but I would not want to watch it again

[tribal quarry]

yea sure thing

xd

[tender shard]

[tribal quarry]

lmao

[eternal oxide]

yep, however politics is expressly banned.

Those discussions never end well

[tender shard]

where does it say that?

[eternal oxide]

Not sure if it is written down but it's been stated by all mods and md5

I'd not know where to even find the rules 😛

?rules

[undone axle]

Please read the rules: http://j.md-5.net/1ikUQuU

[tender shard]

weird, I've seen MANY political discussions here, and nobody ever cared

[tender shard]

thats the IRC rules and it doesnt mention politics at all

the discord rules also dont mention it

which are in the channel description in #general

and the general spigotmc rules also don't mention it

[eternal oxide]

No clue, I've definitely seen md5 ban politics and giving legal advise

[tender shard]

and I've also seen many discussions about politics where staff members discussed, too lol

[eternal oxide]

it does happen but I think it's just a general ban so they can shut down any that go bad.

[tender shard]

hm all I've seen is mods saying to drop "this specific" discussion, but never said it's generally not allowed

[remote swallow]

md avoids the legal advice giving at all occurances

[eternal oxide]

he has to as it's a can of liability worms

[tender shard]

i like worms

slimy, yet nutricious

[eternal oxide]

Gahg - Klingon worms

[tender shard]

how those worms called again that live in mudflats? i remember we went to the sea in netherlands with our school once and people at those worms

alive

[eternal oxide]

live? heck no. We used them as fishing bait was all. Lug worms

Lug worms and rag worms

[lost matrix]

wattwurm. So kenn ichs von der Nordsee

No idea whats it called in english

[tender shard]

ah yes

that's what I meant

[eternal oxide]

Thats a Lug worm

[lost matrix]

You are a lug worm

[eternal oxide]

or it looks to be

yep it's a lug worm (Arenicola marina)

[orchid trout]

[tender shard]

lug worm sounds like slughorn, the new fancy term for "nms"

I think elgatto is fixed now though

[jagged quail]

is haswell affected

[eternal oxide]

no recording Netflix though

[eternal oxide]

probably not

Nope too old.

[jagged quail]

time to check netflix

hmm

[eternal oxide]

it came in close to that though, so you'll have to check

[jagged quail]

it goes black when i pressed screenshot

[eternal oxide]

yep drm'd

[eternal oxide]

I think the 3700 series was the last before they added drm

[lost matrix]

Just need the right tools i guess

[sullen marlin]

Might not be 1080p or greater, 720p often is less drm

[jagged quail]

we have 1080p plan

?notworking

[undone axle]

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

[lost matrix]

Does spigot have an API for that in 1.12?

I know in 1.8 its absent

Shouldnt be too bad then

[tender shard]

?paste it pls

[undone axle]

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

[eternal oxide]

what is the difference between your "works fine" and doesn't work"?

?paste your stacktrace

[undone axle]

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

[eternal oxide]

my bet is you get null when your hand is empty

?paste the full error

[undone axle]

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

[eternal oxide]

We can do nothing without seeing the FULL error

[remote swallow]

im guessing your trying to use a newer api version than the server

[eternal oxide]

just post the error

yep method does not exist, use one of the others

you are using 1.12

[remote swallow]

still 1.12

the website docs are 1.19

[eternal oxide]

1.12 will not have the same methods as other vesions

When I broadcast playerPlacedBlocks in the onBlockPlace function it sends the right list but if I broadcast it on the Mapclear function it sends an empty list. I think it is a problem with the scoop I will really appreciate any help.

    private List<Location> playerPlacedBlocks = new ArrayList<>();

    public MapClear(Plugin PluginMain) {
        plugin = PluginMain;
    }

    public void onDisable_MapClear() {
        playerPlacedBlocks.clear();
    }

    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        if (cmd.getName().equalsIgnoreCase("mapclear")) {
            if (!(sender instanceof Player) || sender.hasPermission("server.mapclear")) {
                Mapclear();
                Bukkit.broadcastMessage("§3Map clear!");
                Bukkit.getOnlinePlayers().forEach(player -> {
                    player.sendTitle(ChatColor.BLUE + "MapClear!!!", " ", 5, 40, 5);
                });
                return true;
            } else {
                sender.sendMessage("§cYou don't have permission to use this command.");
                return true;
            }
        }
        return false;
    }

    @EventHandler
    public void onBlockPlace(BlockPlaceEvent event) {
        Player player = event.getPlayer();
        if (player.getGameMode().name().equalsIgnoreCase("SURVIVAL")) {
            playerPlacedBlocks.add(event.getBlock().getLocation());
            Bukkit.broadcastMessage("Place block "+ playerPlacedBlocks);
        }
    }

    private void Mapclear() {
        for (Location loc : playerPlacedBlocks) {
            if (loc.getBlock().getType() != Material.AIR) {
                loc.getBlock().setType(Material.AIR);
            }
        }
        playerPlacedBlocks.clear();
    }
}```

[eternal oxide]

there is no equipment slot in 1.12

[remote swallow]

are you reusing the same instance

[tender shard]

that's because you create two instances of this class

one for the command, and one for the event stuff

why do you mix command handling and event handling in the first place?

[idle iron]

I am pretty new to programming should I create different classes?

[eternal oxide]

different

[crude cobalt]

Hello there, somebody know how to make it so that arrows can pass through certain blocks that the player cannot pass through?

[mortal hare]

task failed successfully

[lost matrix]

Difficult. Especially because there is a lot of client interpolation happening with arrows.

[eternal oxide]

I don;t see any method in 1.12 for applying attributes to ItemMeta. It was probasbly not implemented in 1.12

Yep looks like attribute in 1.12 is only for entities not Items

https://helpch.at/docs/1.12/org/bukkit/attribute/Attributable.html

probably not in 1.12

[tender shard]

why does IJ suck so hard? VCS -> Share on GitHub does commit all files, BUT ONLY EMPTY VERSIONS!!! like, wtf?

Hey is there a way to remove the half gray seethrough background of a TextDisplayEntity? Previously this was done with setBackgroundColor(), but that seemed to be a bug that has been fixed now.

[chrome beacon]

?paste

[undone axle]

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

[crude cobalt]

Okay, so is there any way to make certain mobs visible only to certain players?

Maybe there's some guide

[tender shard]

Player#hideEntity

[tender shard]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/Player.html#hideEntity(org.bukkit.plugin.Plugin,org.bukkit.entity.Entity)

[crude cobalt]

Thanks

[crude cobalt]

Is there a similar way for blocks?

[young knoll]

Player#sendBlockChange

[tender shard]

as coll said there's only sendBlockChange, but then you manually have to send that periodically, in case they unload the chunk, then come back, etc

[chrome beacon]

It can also cause issues if the blocks hitbox doesn't match what's actually there

[tender shard]

yo spigot finally stopped using @ Deprecated for draft API

[orchid gazelle]

draft api?

[young knoll]

Api that may not be finished

[tender shard]

e.g. Player#hideEntity(Plugin, Entity)

[young knoll]

We changed to ApiStatus.Experimental right?

[remote swallow]

yeah

[tender shard]

yowza

[crude cobalt]

Thanks, you really help me

I created a class in Spigot-api that extends BlockPopulator. Then I added the class I created with getDefaultPopulators in CustomChunkGenerator.

I created this code to get an idea of how it works. I had assumed that all chunks would generate a diamond block.
But only some chunks were generated.
Can someone please help me?

public class OriginalPopulator extends BlockPopulator {

    World w;
    OriginalPopulator(World world){
        w=world;
    }

    @Override
    public void populate(@NotNull WorldInfo worldInfo, @NotNull Random random, int chunkX, int chunkZ, @NotNull LimitedRegion limitedRegion) {

        Location loc = new Location(w, chunkX * 16, 150, chunkX * 16);

        if(limitedRegion.isInRegion(loc)) {// limitedRegion.generateTree(loc, random, TreeType.MANGROVE);
            Bukkit.broadcastMessage(chunkX+","+chunkZ+","+limitedRegion.isInRegion(loc));
            limitedRegion.setBlockData(loc, Material.DIAMOND_BLOCK.createBlockData());
        }
    }
}

https://gyazo.com/9749b95021d431b26cfda0cec6fd3794

[tender shard]

does "isInRegion" ever return false?

[eternal oxide]

? Location loc = new Location(w, chunkX * 16, 150, chunkX * 16);

chunkX twice?

[orchid gazelle]

Yo alex any idea? Do I just look to what the number is nearest, a nth of 45deg?

[tender shard]

tbh I haven't fully understand what exactly you're trying to do. can you make a quick&dirty drawing or sth maybe?

[orchid gazelle]

On my smartphone rn

[tender shard]

to me, making an ugly drawing always gives me ideas on what the possible solution would be, if it's about geometry and stuff

[orchid gazelle]

Imma send you once im on my pc and ping you ok?

[spare radish]

I didn't notice!
Thank you

[orchid gazelle]

Keep in mind that my drawings are REALLY ugly

[remote swallow]

so im gonna have a player data class and a user data, 1st for mc, 2nd for discord but they both need to end up in 1 list, would it better to make an empty interface that both impl with some generic getter in it or do i do 2 lists or just 1 class for both data

[tender shard]

sure

[tender shard]

is every discord user always linked to one MC user?

[remote swallow]

not always

[tender shard]

then I'd keep it as two separate lists I guess. hard to say without more detail

[orchid gazelle]

sorry, replace Y with Z actually lol), its only in 2d space

[remote swallow]

im just thinking and i somehow have to have them link together so if something changes on the discord side its reflected for the player, but idk how i can have stand alone discord, standalone mc and mc + linked discord

[tender shard]

hm maybe you could turn the current yaw into a cardinal direction ( https://github.com/JEFF-Media-GbR/JeffLib/blob/master/core/src/main/java/com/jeff_media/jefflib/data/CardinalDirection.java ), and then decide with a simple switch/case whether to +x, -x, +z or -z ?

that's at least the easiest thing I can think of rn

[orchid gazelle]

well thats 22,5deg, but yeah thanks ill look at it

[tender shard]

yeah just adjust it for 45 and remove the inbetween things like NORTH_NORTH_EAST

but you need the inbetween things to make it accurate IIRC

I'D just do sth like this
switch(direction)
case NORTH, NORTH_NORTH_WEST, NORTH_NORTH_EAST: // it's north, so do -x (or whatever)
case SOUTH, SOUTH_SOUTH_WEST, SOUTH_SOUTH_EAST: // it's south, so do +x (or wahtever)
etc

[remote swallow]

im thinking i do 2 data classes + a wrapper. What could i call a class for user/player data that isnt just UserData or PlayerData

[orchid gazelle]

that sounds easier yeah

[tender shard]

I'd just do UserData, then it has getSpigotUserData() and getDiscordUserData() or sth

idk

[remote swallow]

what could i use for discord data class

currently ive got the PlayerData class for mc

[young knoll]

DiscorderData

[dark arrow]

hey , did minecraft development plugin stopped working ?does it work for anyone?

[young knoll]

Discorder is a word, trust me

[remote swallow]

https://tenor.com/view/mr-bean-wink-trust-me-funny-gif-12503093

ill just use DiscordUserData

[tender shard]

wdym with "not working"?

[dark arrow]

i used to use a plugin called minecraft development which automatically installs all the files and classes (around 7-8 year ago) , now when i try it gives error and i cant create a project until i have disabled the plugin , i can't even open my old projects

[weak meteor]

wdym

Is working perfectly fine

[remote swallow]

check intellij is updated and the plugin is updated

[dark arrow]

i updated my intelliji also

let me send a ss

[flint coyote]

Also it works better with IJ-ultimate from what I heard. I never used the plugin so I cannot confirm or deny that

[tender shard]

to me it causes IJ to crash like every other week

it also is pretty useless, it doesn't really add anything when doing spigot plugins

[remote swallow]

but gradle

[dark arrow]

i get this error on creating a new project

all wierd things happen to me 😦

[tender shard]

looks like the plugin is outdated, or IJ is outdated

[remote swallow]

im pretty sure thats outdated

[tender shard]

you are using some 2022 version, I got 2023.1

[dark arrow]

i downloaded the plugin along with intelligi in my new pc

[tender shard]

show a screenshot of Help -> About

in IJ

[weak meteor]

odk

[tender shard]

that version is a year old

latest is 2023.1

[dark arrow]

oh

[tender shard]

use Jetbrains Toolbox to update IJ

then update to latest mc-dev plugin
