I don't see it

[formal dome]

where can i find the syntax for shading libraries into my plugin.yml

[lavish hemlock]

He registers listeners twice.

[carmine nacelle]

So likee...has anyone here ever worked with custom beehive stuff before..?

or know how they work

like when one is placed, do the bees automatically look for the nearest flowers or

[quaint mantle]

https://www.spigotmc.org/wiki/plugin-yml/

[quaint mantle]

Yiu can just Bukkit.getOnlinePlayers()

Don't need Bukkit.getServer().getOnlinePlayers()

[native nexus]

or use dependency injection

[carmine nacelle]

Well, trying to make a custom entity and already stuck.

    public CustomBee(Location location) {
        super(EntityTypes.BEE, ((CraftWorld)location.getWorld()).getHandle());
    }

EntityTypes is only giving me the option for EntityTypes.g, b...

have they changed that again too?

[ivory sleet]

Yes

            e.printStackTrace();
        }
        return false;
    }```

anyone familiar w/ using sql in java have any idea what i am doing wrong here? getting hung up on while (results4.next()) { appears like the code never executed but everything above it does...

the query 'should' be returning this array from the database

[tardy delta]

any way to make this shorter?

[ivory sleet]

Extract smaller methods

The fundamental rule of a function is that it should only do one thing

And one thing is usually defined by when you cannot meaningfully extract another function from it

As the function becomes more and more specific it’s also natural that the name of the function becomes longer because it does something more specific

[tardy delta]

if it would do one thing i need to have three methods :/

[ivory sleet]

Yes and that’s a lot cleaner

It allows the reader to exit early

[tardy delta]

so i should make a method that handles the cooldown and one for the teleport?

[vernal pier]

Can you spawn an item frame without a block next to

[pastel stag]

@ivory sleet any insight on the issue im having above w/ the sql nonsense?

[opal juniper]

maybe if you disable the physics update

[pastel stag]

or nawww lol im stumped

[carmine nacelle]

Why can't I cast CustomBee to Bee? it extends EntityBee

I can't add my CustomBee to the hive 😦

and can't use the bee methods from it

[solar sable]

how to set a hover event on a onPlayerJoin listener?

[opal juniper]

uh well it doesn’t extend Bee

[carmine nacelle]

Then how do I make a custom one and use the methods from Bee?

[vernal pier]

Don’t think that’s the problem, when I spawn it using world.spawnEntity it throws illegal argument exception. But i can spawn it just fine with the minecraft summon command

It doesn’t throw when there’s a block nearby tho*

[carmine nacelle]

I know I could implement Bee but that adds like 1000 methods

[opal juniper]

oh yeah i forgot it was an entity

idk then sorry

[opal juniper]

yeah true, 🤷‍♂️

[carmine nacelle]

do I have to do it anyway..?

like that's the only way?

[vernal pier]

Can’t u use getBukkitEntity()

[carmine nacelle]

omg i love u so much

homo intended

[solar sable]

bump

[hard fractal]

Anyone here have api for messages title subtitle actionbar etc 1.8-1.17?

[carmine nacelle]

other than ActionBarAPI...?

[hard fractal]

Yes

I know only mf-msg

[deft patrol]

im making a plugin with abilities per class atm and was wondering if i split event listener classes into like one for each class would listening to the same event once for each class be worse than just having it all in one?

[torn shuttle]

public class SpigotMessage {
    public static TextComponent simpleMessage(String message) {
        return new TextComponent(message);
    }

    public static TextComponent hoverMessage(String message, String hoverMessage) {
        TextComponent textComponent = simpleMessage(message);
        textComponent.setHoverEvent(new HoverEvent(HoverEvent.Action.SHOW_TEXT, new Text(hoverMessage)));
        return textComponent;
    }

    public static TextComponent commandHoverMessage(String message, String hoverMessage, String commandString) {
        TextComponent textComponent = hoverMessage(message, hoverMessage);
        textComponent.setClickEvent(new ClickEvent(ClickEvent.Action.RUN_COMMAND, commandString));
        return textComponent;
    }
}

Rate how sexy my utility class is out of 10

I keep forgetting the syntax for these and I'm clearly going to be using it very frequently so here we go

[lavish hemlock]

Pretty alright

Although you are missing 2 things that would make that a pure utility class

final on the class declaration (prevents inheritance)
private constructor (prevents instantiation)

• you can also avoid reflection via throwing an exception within the constructor

[torn shuttle]

private constructor?

[lavish hemlock]

It's like a private method

it can only be called by the class it belongs to

[torn shuttle]

why would I do that?

[lavish hemlock]

to stop people unnecessarily instantiating your utility class? (which is important for an API)
plus it provides a bit more context as to what the class is for

[ivory sleet]

Yeah

Even the class Objects do that

[lavish hemlock]

ye

[ivory sleet]

even throws an AssertionError in its init

[lavish hemlock]

I tend to throw UnsupportedOperationException myself

[ivory sleet]

I always throw AssertionError

but both works

[torn shuttle]

I guess I don't really see the point in doing that when this is for a solo project lol

[ivory sleet]

yeah its not necessary ofc

[lavish hemlock]

fair? I typically do it all the time tho just as a personal thing tho

[ivory sleet]

But I like to write my code defensively Ig

[lavish hemlock]

but uhhh that's coming from a person who uses final on 99% of his local variables

[torn shuttle]

I used to use final quite a bit more

[ivory sleet]

same

[torn shuttle]

but then I did a 250 class refactor

and uh

I changed my mind on that one

[lavish hemlock]

man I used to use it on fuckinnnnn

[native nexus]

im lazy

[lavish hemlock]

ARM resources and parameters

[ivory sleet]

I used final because it occasionally would spare some bytecode instructions

but its negligible

[lavish hemlock]

just kotlin it

[ivory sleet]

so stopped with the final clutter

[lavish hemlock]

ez

[torn shuttle]

it makes sense if you're working on a project with a lot of people but the opening statement of my project says I don't take pull requests lol

[ivory sleet]

hehe

[lavish hemlock]

why not?

[torn shuttle]

just want this to be a project I wrote from end to end

[native nexus]

"code is mine, no touchy"

[torn shuttle]

it's open source and gplv3, I just also want it to be something I made

[ivory sleet]

ye thats totally fine

[lavish hemlock]

I mean GPL isn't as open as it could be, but yeah I understand

[torn shuttle]

gplv3 is exactly what I want it to be

[lavish hemlock]

I'm an MIT License guy myself

[ivory sleet]

wtfpl 😄

[lavish hemlock]

...
if you look at any of my projects they're all under MIT

[tardy delta]

Why would People make objects of An utility class of it has no purpose?

[lavish hemlock]

because people are idiots

[ivory sleet]

I use mit mostly but yeah sometimes something else

[tardy delta]

Smh

[torn shuttle]

by mistake

[lavish hemlock]

that too ^

you can also use it if you want to force your class to use a builder

since nested classes are able to instantiate their parent classes if they have private constructors

[ivory sleet]

yea

parent classes constructors can be public also

[lavish hemlock]

ye I know

I was just stating that private works

[ivory sleet]

ah alr

[lavish hemlock]

I know everything about Java

don't test me, or you die

[ivory sleet]

Name every possible variable

🤡

[lavish hemlock]

what does that even mean

[native nexus]

hold your horses

[lavish hemlock]

oh fuck

[tardy delta]

Oh

[lavish hemlock]

well technically

every possible variable depends on the size of the call stack

[torn shuttle]

you know java? name every exception that I have triggered today

[carmine nacelle]

Is it a bad idea to save a list of custom objects? or should I just loop through the list and save the values I want

[lavish hemlock]

as you said "variable" and not "field"

[ivory sleet]

fields are variables in a sense

[lavish hemlock]

ehhhhh it's kinda like squares and rectangles

a field is a variable, but a variable isn't a field

[ivory sleet]

yeah

[tardy delta]

A rectangle is a square?

🤠

[lavish hemlock]

yeah

[wide flicker]

[a-zA-Z$_][a-zA-Z0-9_]{0,65534}

[ivory sleet]

square isnt a rectangle

[ivory sleet]

🌞

[lavish hemlock]

a rectangle is a square, it's a 4-sided, closed shape

the difference is l e n g t h

[tardy delta]

Ow i was thinking about the work Triangle smh

😔

[ivory sleet]

maow have u messed with jigsaw and serviceloader

[native nexus]

Can we take this to #general You guys are ignoring someones question

[ivory sleet]

I thought it was going to be tricky but it was quite simple despite going under one of the more advanced java topics

[lavish hemlock]

this goes too far above the maximum name limit

[ivory sleet]

Indeed, good point

[torn shuttle]

ah feels good to use text components like this

should've done this ages ago

                TextComponent bossTrace = SpigotMessage.commandHoverMessage(ChatColor.BLUE + "Boss trace!",
                        "Remember, it requires debug mode to be on! This is used for advanced debugging, ask on discord if you want to know more about it.",
                        "/elitemobs trace " + customBossEntity.getEliteUUID().toString());

c o m f y

[lost matrix]

Lets see.
What does this code print out:

  public static void main(String[] args) {
    Integer a = 10;
    Integer b = new Integer(10);
    Integer c = Integer.valueOf(10);
    System.out.println(a == b);
    System.out.println(b == c);
    System.out.println(a == c);
  }

[lavish hemlock]

welllll

valueOf likely returns a cached version of the Integer

[ivory sleet]

ye

[lavish hemlock]

I wonder if the autoboxing would use valueOf or the constructor?

[ivory sleet]

former I presume

[lost matrix]

valueOf and implicit creation does

[lavish hemlock]

oh so then

false
false
true

?

[lost matrix]

Yeah. How big is the default Integer cache of the jvm?

[eternal night]

:>

[ivory sleet]

<:

[lavish hemlock]

hmm

[hasty jackal]

I think somewhere around 100-200 values iirc

[ivory sleet]

I'd guess 512

[lost matrix]

One byte in size
-127 to 128

[ivory sleet]

oh nvm

[eternal night]

2⁸

yea

[vernal pier]

How do I summon an item frame without a block next to

[eternal night]

tho can't you like, expand the integer cache ?

[lost matrix]

Yeah there is a jvm flag for that

[eternal night]

yea ha

[ivory sleet]

Does Long also have a cache?

(by default)

[lavish hemlock]

all primitive wrappers do

[lost matrix]

Did you try just summoning one?

[ivory sleet]

Even Float and Double?

[vernal pier]

Whenever I do world.spawnEntity for item frames it throws illegal argument exception when there’s no nearby block

[lost matrix]

Ive never seen a floating item frame to be honest.

[vernal pier]

It’s possible

[eternal night]

They die after a while don't they ?

[vernal pier]

When I use the minecraft summon command it works just fine

[lost matrix]

Some more 😄
LinkedList is utter garbage. What is the only use case where it excels.

[lavish hemlock]

Hard question

I know from StackOverflow it's not very quick compared to ArrayList and it's very memory inefficient (as it uses linked nodes)

[ivory sleet]

What's the parallelism for the common pool?

[lavish hemlock]

aight well I don't even work with concurrency lol so

good job calling that out

[lost matrix]

For the LinkedList: Removal of elements while iterating is O(1) and the only thing its good at.

[ivory sleet]

oh lets skip that also

adding is also O(1) innit?

[lost matrix]

parallelism i would suspect the number of cores of the cpu?

[carmine nacelle]

    public boolean setupCore() {
        if (getServer().getPluginManager().getPlugin("CadiaCore") == null) {
            return false;
        } else {
            this.cadiaCore = (CadiaCore) getServer().getPluginManager().getPlugin("CadiaCore");
            return true;
        }
    }

Soooo..my core plugin is saying it's null, even though the return for this is "true" (meaning it successfully found the core dependency plugin)

[lavish hemlock]

Ooh, that's actually cool.

[carmine nacelle]

whats up with that

[lost matrix]

Yeah insert and remove while iterating.

[ivory sleet]

Yeah iirc something like that although changeable with a jvm flag

[carmine nacelle]

but if I try to reference the core, it says it's null

[lost matrix]

Do you make sure to call setupCore() before referencing cadiaCore and that you only use one instance of the class that contains this field?

[carmine nacelle]

Yeah,

    public void onEnable() {
        if (!(registerDependencies())) {
            getServer().getPluginManager().disablePlugin(this);
            return;
        }

        registerClassInstances();
        configManager.loadHiveConfig();
        configManager.loadHives();

        registerListeners();
    }

I'm not referencing it until my listener, which is the last thing called.

[lost matrix]

Let us see how you obtain your cadiaCore instance. A stack trace would be nice too 😄

[carmine nacelle]

Error: https://pastebin.com/raw/Yx4zRVns

[carmine nacelle]

and..

[lost matrix]

And registerDependencies() calls setupCore()

[carmine nacelle]

So this:

this.cadiaCore = (CadiaCore) getServer().getPluginManager().getPlugin("CadiaCore");

it's null, otherwise it would return false, then disable the plugin

yeah

    public boolean registerDependencies() {
        if (!(setupEconomy() || !(setupCore()))) {
            return false;
        } else {
            return true;
        }
    }

[native nexus]

You can make nicer return statements

[lost matrix]

just

    public boolean registerDependencies() {
        return setupEconomy() && setupCore();
    }

[carmine nacelle]

done

but thats not my issue lol

[native nexus]

We are aware but looks cleaner 😛

[carmine nacelle]

true

i like clean

[lost matrix]

Could be. Your statement looks a bit off

[carmine nacelle]

hence grouping everything together and having my onenable just calling other methods to do the dirty work

Still have the error

[lost matrix]

Show us how your PlaceHiveListener class looks like.

[carmine nacelle]

actually, another error: https://pastebin.com/raw/pf4Xq3kp

[lost matrix]

Ah i know the problem. You shade your CadiaCore plugin in.

Set the

<scope>provided</scope>

in your pom.xml

Or do you use Gradle?

[carmine nacelle]

I'm using it as a jar dependency

[lost matrix]

Ah. F i guess.

[native nexus]

Highly recommend looking into maven or gradle

[carmine nacelle]

I use maven for stuff like spigot

[regal dew]

just gradle

no maven

gradle kotlin dsl

[native nexus]

Why not maven?

[lavish hemlock]

beautiful

[carmine nacelle]

but I dont really feel like pushing every change I make to the core plugin to github and stuff

[native nexus]

You don't have too

You can include the core via a dependency in maven

[carmine nacelle]

How?

they are both maven projects..so..

[regal dew]

do u really like writing xml

[native nexus]

Yeah floats my boat

[lavish hemlock]

I fucking hate XML

[regal dew]

or cartesian product lookup of dependencies in repos

[native nexus]

I write XML daily

<repository>
  <id>project.local</id>
  <name>project</name>
  <url>file:${project.basedir}/repo</url>
</repository>
``` `mvn clean` `mvn install` Then you can include it as a dependency in any of your projects. Just make sure to shade it in ofc.

If there is a better way todo it lemme know lol

[carmine nacelle]

That goes in core?

[native nexus]

Yes

[carmine nacelle]

Does that go with my other repos or up towards the top?

[native nexus]

Yep with your other repo's

[carmine nacelle]

and would the id be the same as my groupID?

[native nexus]

Yeah

[native nexus]

why is your group id for the dependency project.local? that is where you define the actual proper group id for the core

<repository>
  <id>project.local</id>
  <name>project</name>
  <url>file:${project.basedir}/repo</url>
</repository>
``` This goes in your core POM

``` This goes into your other projects POM

It's not hard

[carmine nacelle]

😮

works

[native nexus]

Yay!

[carmine nacelle]

wild

[native nexus]

There yah go!

[carmine nacelle]

so every time I update the core I have to run the mvn commands again..?

[native nexus]

Yep otherwise it won't know the changes

The best approach is to honestly use modules when utilizing a core

[carmine nacelle]

alright

but

[native nexus]

https://www.youtube.com/watch?v=XqC1zeFdxMs

[carmine nacelle]

still getting the cast error..

[native nexus]

Could you show me that error?

and source

            return true;
        }
    }

63 is

this.cadiaCore = (CadiaCore) getServer().getPluginManager().getPlugin("CadiaCore");

[native nexus]

What is the Declaration for cadiaCore variable?

[carmine nacelle]

Isn't that what I sent?

[native nexus]

What is the type for CadiaCore, did you make it Plugin or JavaPlugin?

[carmine nacelle]

public CadiaCore cadiaCore;

extends JavaPlugin ofc

[native nexus]

I have never casted to a JavaPlugin before

What happens when you create a static instance of your core class and get it that way?

[carmine nacelle]

No I just mean in the core:
public class CadiaCore extends JavaPlugin {

I always use dependency injection across classes instead of a static instance method

[native nexus]

public class CadiaCore extends JavaPlugin {

  private static CadiaCore instance;

  @Override
  public void onEnable() {
    instance = this;
  }  

  public static CadiaCore getInstance() {
    return instance;
  }
}
``` Try this and see if getting the static instance works.

[carmine nacelle]

Yes

[wide flicker]

Do you have CadiaCore set as a dependency for CadiaBees in the plugin.yml?

[carmine nacelle]

yes

https://hastebin.com/detavugaku.properties

now im getting this tf

[wide flicker]

@carmine nacelle Did you put this in your CadiaBees plugin? You're missing the CadiaBees class now

[white thicket]

How to create bungeecord config file?

[native nexus]

com.squallz.CadiaBees.CadiaBees seems incorrect

[white thicket]

this.getConfig() doesn't seem to work for bungeecord

[carmine nacelle]

How?

[wide flicker]

package names should be lowercase

[carmine nacelle]

ok but..

minor details

Idk why it suddenly can't find the main class of that plugin

[native nexus]

Yeah but that is important to run your plugin 😛

[carmine nacelle]

Well, the last build on it failed with this

Double check your CadiaBees class definition

[carmine nacelle]

pretty sure its cause it didnt build correctly

wot

I dont get why its just now throwing this error

[white thicket]

anyone?

[carmine nacelle]

@native nexus Seems to have compiled fine but still not letting me cast it

java.lang.NullPointerException: Cannot read field "hologramManager" because the return value of "com.squallz.CadiaCore.CadiaCore.getInstance()" is null

this is so annoying holy shit.

[pastel stag]

@lost matrix yo do you know anything about java + sql?

like getting data from an sql database and using it in a method as a string or otherwise

[deft patrol]

why are there so many blockface directions? from what i can tell i only need north, south, east, west, up and down

[quaint mantle]

is there anyway to modify a sent packet ?

for example an armorstand's metadata

it's displayname forexample

[wide flicker]

Because some 'blocks' can face more than just north/south/east/west/up/down

[deft patrol]

which blocks does that apply to?

[lost matrix]

Yes. You can listen for outgoing packets using ProtocolLib

[quaint mantle]

please not that trash plugin

[wide flicker]

If it already was sent, no. Pretty sure there's stuff out there for listening for when packets are sent so you can modify them though.

[quaint mantle]

a sent packet that i have it's id

[wide flicker]

Signs come to mind

[lost matrix]

Then inject your own netty pipeline handler

[deft patrol]

ah i see, alright thanks for the info

[quaint mantle]

if i send the metadata packet again, will it change ?

[quaint mantle]

i dont know how to use netty.
so if i use it, it will cause performance issues

[carmine nacelle]

Protocollib? Trash plugin?? LOL WHAT

[quaint mantle]

best performance ngl

[carmine nacelle]

Then how is it trash.

[quaint mantle]

the performance is trash

[lost matrix]

Yes. Its a bit of overhead but i suppose you can just overwrite the metadata by sending a second packet.
And ProtocolLib is a well established and battle hardened plugin.

[carmine nacelle]

I've never had a single issue with it.

[lost matrix]

https://tenor.com/view/huh-rabbit-cute-gif-15676652

[carmine nacelle]

Still having my issue with getting the core plugins instance btw..

[quaint mantle]

the other plugins might be causing it so ?
plugins using plib

[wide flicker]

Still the casting issue?

[carmine nacelle]

Can't blame procollib for that one

Yep.

Even using static instance

[wide flicker]

Version of core the same as the one being used on the server? (No changes to that class?)

[carmine nacelle]

Well with static instance it's just null.

It's all up to date, restarted server

Re exported both.

[lost matrix]

My servers only ever have 3 plugins:
My core library
The server logic
ProtocolLib

[wide flicker]

RegisteredServiceProvider<CadiaCore> provider = Bukkit.getServicesManager().getRegistration(CadiaCore.class);
if (provider != null) {
  this.cadiaCore = provider.getProvider();
}```Try this

[lost matrix]

You need to make sure that you dont export your core lib with your plugin

[lost matrix]

And dont try this

[wide flicker]

Why not?

[carmine nacelle]

It's set to provided.

[lost matrix]

Because this is not the root of his problem.

[lost matrix]

How do you compile your plugin?

[carmine nacelle]

Build > build artifacts

[lost matrix]

Do you use maven?

[carmine nacelle]

Yeah but to make the jar I build artifacts

[lost matrix]

Then you can throw your pom.xml in the trash because it doesnt get used anyways.

[carmine nacelle]

Uhhh it does for my dependencies

[lost matrix]

No it doesnt.

If you dont know what all the maven lifecycles do then just use
mvn clean install

[quaint mantle]

how to get the datawatcher

[carmine nacelle]

If I delete my pom then I lose all my spigot API references, protocollib, it's 110% needed

[lost matrix]

The nms entity has a getter method for that

[carmine nacelle]

Tried it anyway. Provider is null. :D

[quaint mantle]

as.getDataWatcher for example
but aren't they different for each armor stand ?

or it is the datawatcher of entityarmorstand

[lost matrix]

What you need to do is simply build your plugin with maven. What IDE do you use?

[carmine nacelle]

IntelliJ.

That's still not my issue though.

[lost matrix]

Every Entity instance has its own DataWatcher

[carmine nacelle]

Once the plugins are in the server, how they're compiled changed nothing

[lost matrix]

Yes it is.

[carmine nacelle]

Why is it just now an issue once I try using my own dependency

[quaint mantle]

you mean armorstand 1 datawatcher is not the same as armorstand 2 ?
or entityarmorstand and entityzombie

[carmine nacelle]

Every entity has it's own.

[quaint mantle]

what do you mean by entity!!!

[lost matrix]

The class

[quaint mantle]

you mean armorstand 1 and armorstand 2

[quaint mantle]

ok

means if i do as.getDataWatcher()

it works with another armorstand right ?

[carmine nacelle]

"no valid maven installation found" excuse me what

[lost matrix]

https://mkyong.com/maven/how-to-install-maven-in-windows/

[carmine nacelle]

I don't get how my maven home directory is inside

Invalid*

Already did that

And it's in my path

[carmine nacelle]

Got it

Shows a version now

https://i.gyazo.com/2d90092ccd4f9b425a5eb5c0052b17e0.png

its been showing this for a while but still works fine

idk what thats about.

[lost matrix]

Then type mvn clean install into the terminal window or use IJs helper buttons

[carmine nacelle]

It does that all the time idk why

But

I did the clean install thing again

Now what?

[lost matrix]

Did you build the plugin?

[carmine nacelle]

I clicked clean and install

If that builds it then yeah lol

It gave me a jar

[lost matrix]

In your "target" folder?

[carmine nacelle]

It's named very inconveniently

Yes

[lost matrix]

Try it out 😄

[carmine nacelle]

Ok...explain

and how can I make the mvn build export directly to my plugins folder instead of some random folder

[lost matrix]

Building artifacts doesnt use your pom.
Building with maven does.
So if you build an artifact then you copy your dependencies into your jar
if you use the pom then you can define the scope.
PS: There is also a way of not shading the dependencies without using maven

[carmine nacelle]

https://i.gyazo.com/183729a8e1bcda4fd86b24589e65d701.png well my artifact isnt set to include the other one

[white thicket]

Is there any event for when a falling block lands? Tag me if replying me pls ty

[carmine nacelle]

@lost matrix any idea...? it keeps exporting to the target folder in the project, I need it to export to my plugins folder like it was with the artifacts

[fading lake]

I detect falling block changes like this, it's probably not the best way, but the best way I can think of at this moment

@EventHandler
private void onBlockChange(EntityChangeBlockEvent event) {
    if (event.getBlock().getType() == Material.AIR || !event.getBlock().getType().isBlock()) {
        Bukkit.getScheduler().runTask(Main.getInstance(), () -> {
            if (event.getBlock().getType() == Material.SAND || event.getBlock().getType() == Material.GRAVEL) {
                event.getBlock().getWorld().playEffect(event.getBlock().getLocation(), Effect.STEP_SOUND, event.getBlock().getType(), 20);
                event.getBlock().getWorld().getBlockAt(event.getBlock().getLocation()).setType(Material.AIR);
            }
        });
    }
}

its just a simple thing that kills gravel and sand falls regardless of what they land on

[lost matrix]

Uhm thats probably not what you should do

Get the entitiy and cast it to FallingBlock. Then get the BlockData/Material from it.

[fading lake]

it works, somewhat

[lost matrix]

One moment

[frank steeple]

Is there maybe event.getentity.remove, it may prevent lag on large amounts of blocks

[fading lake]

oh so right start, wrong exit

[frank steeple]

Also why are u running it in scheduler?

[lost matrix]

  private static final Set<Material> CLEANED_TYPES = EnumSet.of(Material.GRAVEL, Material.SAND);

  public void onFallingBlockHit(final EntityChangeBlockEvent event) {
    final Entity entity = event.getEntity();
    if (entity instanceof FallingBlock fallingBlock) {
      final Material material = fallingBlock.getBlockData().getMaterial();
      if (CLEANED_TYPES.contains(material)) {
        // Play sound here
        event.setCancelled(true);
      }
    }
  }

[carmine nacelle]

this mans a legend

[white thicket]

Why scheduler?

[carmine nacelle]

Output path is... C:\Users\jflee\Desktop\Test Server\plugins
maven outputs to... C:\Users\jflee\IdeaProjects\CadiaCore

why.

[lost matrix]

The Block is changed after this event was fired. So he checks the type in the next tick.

[fading lake]

to destroy the block after if I remember, since most events are pre-it-happening

[lost matrix]

You need to define the output dir in your pom somehow.
From now on everything compilation related is done in your pom.

[white thicket]

oh so we have to do that to wait a tick and stuff?

I am actually trying to make it so when any falling block is dropping and if block below it is something then it will break

[carmine nacelle]

I found this page https://intellij-support.jetbrains.com/hc/en-us/community/posts/360010717260--SOLVED-Maven-Set-target-output-directory but version 2.3.1 isnt showing, how do I get the latest version..?

ok got that but I dont want my output jar to have SNAPSHOT on the end it looks dumb & is unnecessary

[lost matrix]

Then change your artifact version...

[lost matrix]

No you should not do that as it leads to quite a bit of overhead. Rather use the method i just proposed

[white thicket]

Which one?

[carmine nacelle]

I didn't want a version on it at all. I just wanted the plugin name but I figured it out, thx for the help guys

[lost matrix]

#help-development message

[white thicket]

What happens with you cancel the event?

[lost matrix]

I think the block just vanishes.

[white thicket]

can I break it instead?

like drop it in item form?

[lost matrix]

Sure

[white thicket]

How so?

[lost matrix]

Either dont cancel the event and break the block one tick later
or
Cancel the event and manually drop an ItemStack at the Location

[white thicket]

hmm I will actually just remove it

[halcyon mica]

So it looks like entities are unable to actually leave 2 block deep water

As in, jumping out

Did anyone figure out how to let them leave deep water yet

[slim kernel]

What ItemStack do I get when doing getCursor() in the InventoryClickEvent?

[floral panther]

hey can anyone help m

i am developing a server

but i can't make a void mutiverse

can anyone help?

[solid cargo]

why do i always misread "pom" to something else..

[maiden briar]

Why can't I update the scoreboard async? The timings told me it is 600% of a tick

[tall dragon]

The itemstack that the cursor is holding. If any

[slim kernel]

thank you

[hollow bluff]

How may I go on about fixing this issue https://paste.md-5.net/yoyejiceke.sql ? I tried adding a delay for the method that loads a selected world but I don't think that one was the problem and I'm just not sure how to go on about this

[maiden briar]

The world does not exist @hollow bluff

[hollow bluff]

The world exists, it just doesn't load when the server first starts

Everything works after when doing /rl but when first starting the server, it doesn't load

[maiden briar]

Then idk what is wrong here

[quasi flint]

do i smell 1.8?

[hollow bluff]

It doesn't matter what version, have the same issue in later versions as well

[quasi flint]

still,1.8 long depricated and abandoned by paper and shit

[hollow bluff]

The answer I got yesterday when I asked was that it takes time for a world to load, so I don't know how to even fix it

[quasi flint]

delay the execution of ur code

[hollow bluff]

I tried adding a delay but the error still came

[quasi flint]

long enough delay?

like 5 min after the world loaded

to make sure

[hollow bluff]

._. It's a minigame, for sure I dont need to wait 5min

[quasi flint]

just for testing my guy

[hollow bluff]

ah ye

[quasi flint]

to see if ur code works properly at all

[hollow bluff]

Added a delay, the error just comes regardless

Can't be the method I use to load them at all

[quasi flint]

then bad code

[hollow bluff]

thanks for the kind help 👍

[quasi flint]

wouldnt make sense if it wasnt faulty code

could i see the piece of code that errors?

[hollow bluff]

for sure! Gimme a second

[quasi flint]

and the onEnable line 38

thats one linethat throws an error

[crude sleet]

Hey guys, i have a Problem: I created an entityarmorstand and put it on the player's head, the only problem is if I move over 31 blocks away from the player and then come back again, he is no longer on the head of the other player. I could of course send the packet again in the move event, but I think that's a bad solution.

[hollow bluff]

https://paste.md-5.net/okaqaseluc.java this includes the config and the onEnable line

[quasi flint]

config existing?

[hollow bluff]

yes

[quasi flint]

as a yml?

[hollow bluff]

in the server files? yes

[quasi flint]

because there has to be smth bad going on there

[quasi flint]

does it get created in the plugin folder?

[hollow bluff]

https://paste.md-5.net/ihozoruheq.java maybe the full onEnable might be relevant after all?

[quasi flint]

sure u called the config creation thingy?

[hollow bluff]

It should be called

[quasi flint]

should

[hollow bluff]

haha yeah... the config.yml is called at the top, the arena.yml is called right under?

[quasi flint]

well now i am completly bamboozeled

u readin the right config

i dunno if i can help

maybe someone else

[deft patrol]

is a block iterator or block raytrace faster?

[true perch]

I have been studying java for the last 8 months and working on a spigot plugin for the last 2 months. I've already invested about 300 hours developing the plugin and nearly everything is running smoothly. I'd love to show my code to an experienced developer to get feedback; I was thinking it would be amazing to have a one on one in a voice call to go through the code and discuss what could be improved. I have some ideas for how I can improve on the areas that aren't as fast, but I would really like to talk to someone about it. If you're interested please dm me!

[unreal quartz]

stick it on github and let the masses rip into it

[true perch]

I'm afraid if I put it on github people will steal the code

[maiden briar]

net.minecraft.server.v1_16_R3.PacketPlayOutScoreboardDisplayObjective

Can somebody tell me what the fields of these constructors mean?

[eternal oxide]

Theres nothing you have written thats not been written a hundred times before.

[hollow bluff]

It should be reading the file yeah but it's fine if you can't help, thanks anyways

[quasi flint]

there are a thousand different languages, but he chose to speak facts

[crisp arch]

If i did /foo bar baz, what would the args variable contain?

[unreal quartz]

[bar, baz]

[crisp arch]

would it contain ["foo", "bar", "baz"]
or
would it contain ["bar", "baz"] -

oh

[crisp arch]

thanks

[quaint mantle]

what is a task id and how to get it

[eternal oxide]

you get teh task id when you schedule it

[hasty prawn]

Aren't task ids deprecated

Supposed to be using BukkitTask now

[opal juniper]

yeah but it didn’t get removed

[quaint mantle]

what is a datawatcher

i used as.getDataWatcher() for example

but now i dont have an armorstand

[opal juniper]

data watcher handles sending packets iirc

as in

[quaint mantle]

how to get one

[vernal pier]

Hello I am trying to allow users to input a image that my plugin will read in the config, how should I do this. Ik I can let them put in a url or file path but how do I allow both to work

exampleimage: imgur.com/... or image: plugins/image.png

[opal juniper]

when a packet needs to be sent the data watcher detects it

[quaint mantle]

what should i set here

[opal juniper]

there is a method under one of the entity class

[quaint mantle]

bruh

what should i set

please tell

i dont have armorstand

but i have id

of the armorstand

[opal juniper]

idk how to get the data watcher of an entity that doesn’t exist lol

[solid cargo]

how can i get the servers' tps

[quaint mantle]

they said datawatcher is for the class

[opal juniper]

on spigot the only way is to crudely calculate it yourself or reflect into a private field- on paper there are tick start / finish events as well as making the last tps accessible

[maiden thicket]

table doesnt exist

[golden mortar]

How can I get the orientation of an dispenser? (or, to ask the question more broadly, how can I retrieve metadata of a block)

[tribal sparrow]

does anyone know why when i spawn a boat and add the player as a passenger it add the player but you're looking the opposite way to which you I it?

                Boat boat = (Boat) player.getWorld().spawnEntity(event.getClickedBlock().getLocation(), EntityType.BOAT);
                boat.addPassenger(player);

[eternal oxide]

you are spawning your boat inside a block

[tribal sparrow]

Boat boat = (Boat) player.getWorld().spawnEntity(event.getClickedBlock().getLocation().add(0, 1, 0), EntityType.BOAT);
                boat.addPassenger(player);
``` no its spawned 1 block above i just removed that part to post here

[eternal oxide]

Not tyhe code you showed, but ok

[tribal sparrow]

and also is checked to see if on water etc... but im just wanting to know if there is a way to add the player facing the correct way

[eternal oxide]

You are getting the location from the block so your boat will use the facing of the block, if it has one.

[tribal sparrow]

is there a way to set it to the way the player is facing?

[eternal oxide]

yes, get the direction of the player and set it to the boat

[tribal sparrow]

i'm doing it by the clicked block as i'm detecting if a player has right clicked a block from the interact event, cancelling then spawning the boat and entering the boat.

maybe i should do it from the players loc and enter the boat?

player.getDirection?

[quaint mantle]

what kind of black magic have hypixel used, so the player's can't even break the blocks ?

[dense remnant]

Adventure Mode

[quaint mantle]

um that doesn't make sense

it shows u that u r mining the block

[eternal night]

Don't they give you mining fatigue or smth

[quaint mantle]

true

but doesn't ur hand move slowly if u have mining fatigue ?

[stone sinew]

You can set items to not be able to break blocks.

Without adventure mode I think.

[slim kernel]

How can I check in the InventoryClickEvent if a Player clickes on a blank space? I tried both of these:

event.getCurrentItem().getType == Material.AIR
event.getCurrentItem() == null

but somehow it doesnt work

[wild reef]

Hey quick question. I want to deny a player to interact with everything like chests aso. But when I am opening the chest from a minecart it won't get blocked. Is there a special event for these cases?

[quaint mantle]

opening chest from lore?

wdym

[wild reef]

interacting with a Minecart which has a chest inside it

[quaint mantle]

you can just cancel playerinteract event

InventoryOpenEvent?

you keep in mind everything that is a container

inventoryOpenEvent

[wild reef]

Okay I will try that, but shouldn't be the interact event like superior?

just wondering

[mystic tartan]

is there a character limit to the player list header?

Does the InventoryClickEvent even get fired if you click on an empty space

[solid cargo]

ugh... this does not work. porque?

also no errors in the console

[quaint mantle]

hello i have a problem with ubuntu 20.04.3, gradle and adoptopenjdk 16
when i compile my gradle project in intellij with adoptjdk 16
it is weird.
some listeners doesn't get registered
error line 113
my class is 90 lines
when i switched to windows 10 (im using grub dualboot) the problem was solved
and i opened a project created in intellij 2020 and gradle 5
what could be the problem ? if i compile with a newer version of gradle or create the project IN ubuntu will it be fixed ?

[slim kernel]

you mean the number of slot that is clicked?

And how can I check when someone clicks on an empty slot?

[golden turret]

how do i do something like this:

i have this regex: test (\S+) (\S+)?

[slim kernel]

like this:

event.getCurrentItem().getType() == Material.AIR

[golden turret]

as you can see, the 2nd group is optional

[golden turret]

i want that when im getting the groups, if that group is not specified it becomes null

[solid cargo]

@last temple ok i added this. the Score score1 = blah blah blah thing

so i need more?

for it to work?

[slim kernel]

so its right how I did it?

[solid cargo]

but @last temple , when i watched kody Simpson, i believe he didnt add criteria

[gritty urchin]

yeah but they lag behind, even when teleporting every tick

[solid cargo]

like, i did manage to make a sidebear, but im struggling with the player_list

ok

[slim kernel]

Whats the problem?
Error:
https://gist.github.com/ItzJustNico/e1e05ba26452fe0811f031d12783ccc0
Line 131:

if (event.getCurrentItem().getType() == Material.PLAYER_HEAD && event.isLeftClick()) {

[young knoll]

Item is null

[tardy delta]

can someone explain me what a CompletableFuture<T> is?

[quasi flint]

a little bump

[solar sable]

what are you trying to achieve? explain it more

[slim kernel]

@solar sable wait i think i got it

[ivory sleet]

What do you need explained?

[solar sable]

is it citizens? or its your own plugin

[quasi flint]

Own

[solar sable]

well how are we supposed to know if its your own?

show the info or something to let us see how to remove it

[quasi flint]

Gimme a quick sec

[solar sable]

good

[quasi flint]

this is how i send the packets to the player

[solar sable]

this is like the carpet mod lmao but anyways

so maybe

wait

you havent made anything to remove it yet right?

like a command to remove it or something

[quasi flint]

Yea i Made it

Just acouple lines below it

Sende the PacketPlayOutDestroyEntity

Or what ITS called

Not in PC rn

[solar sable]

hmm

[quasi flint]

And the EnumPlayerInfo.Remove_Player

[solar sable]

well have you tried /kill @e yet?

because if the command doesnt work then idk what does

[quasi flint]

Not completly remove it

Just hide it in the tablidt

The removing Part already works

[solar sable]

aah

[quasi flint]

But it completly

Without the way of only deleting it out of the tablist

[solar sable]

well most of plugins online like citizens and such, do have that type of stuff when you are far away from the npc and then goes back to it, it loads in the name in the tablist and then dissapear

well im not an expert in this, so i will let an expert take handle of this situation

[ivory sleet]

Imagine if minecraft just would add native npc support

[quasi flint]

So they do it somehow

[quasi flint]

Too good to be true

[solar sable]

bedrock edition that already has npc

cries in java

[ivory sleet]

🥲

[quasi flint]

So nobody knows the answer for it?

[solar sable]

well i wouldnt say "nobody"

just wait until an expert of this type to respind

respond*

[ivory sleet]

Yeah, create a thread maybe

[solar sable]

yuh

[quasi flint]

Ok will do

[solar sable]

how to detect when a player chat in mc?

[quasi flint]

Delete Packet NPC only out of Tablist

First thread I ever made ;7

[solar sable]

or much specifically, how to detect when a player say a specific word/text in chat

[ivory sleet]

AsyncPlayerChatEvent then filter the message

[quasi flint]

.contains and so on

[solar sable]

aah

okie doke

also i asked this before but it didnt work so imma ask it again, how to set a hover event using just basic java language and not json format

[quasi flint]

What in god's name is a hover event

[solar sable]

cause i want to make it when i join it just puts a hover event saying something like "hello"

[solar sable]

you do not know what a hover event is?

what about click event?

[quasi flint]

Well that sounds more familiar

[solar sable]

hover event is just basically

shows a text above a text

so like "hello" and then when you put your mouse over it, it shows a text

[quasi flint]

No clue tho sorry :c

[ivory sleet]

Oh yeah

ComponentBuilder

[solar sable]

component builder?

[ivory sleet]

Yessir

?bc-c

1 sec

[solar sable]

whats that?

[ivory sleet]

?bcc

A command

Supposed to work

[solar sable]

i mean like whats a component builder lol

[ivory sleet]

?jd

[undone axle]

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

[ivory sleet]

Oh

[quasi flint]

But no workin

[ivory sleet]

https://javadoc.io/doc/net.md-5/bungeecord-chat/latest/index.html

Here

Find the ComponentBuilder

It’s basically a class to concatenate components

[solar sable]

uh okay

does it have anything to do with hover event?

[ivory sleet]

Indeed

[solar sable]

GOT IT!

time to leaarn

[golden turret]

https://docs.oracle.com/javase/8/docs/api/java/util/concurrent/CompletableFuture.html

[ivory sleet]

Well easiest way to do what u want is something like
BaseComponent b = new TextComponent("text");
b.setHoverEvent(HoverEvent(HoverEvent.Action.SHOW_ITEXT, new Text("hover text")));
player.spigot().sendMessage(b);

I think

[golden turret]

https://www.baeldung.com/java-completablefuture

[ivory sleet]

Typed on phone so yeah

[tardy delta]

aha a thing that will be completed at some time

[solar sable]

ah okay

[ivory sleet]

Well

[solar sable]

ill check on intellij and see if it understands it lol

[ivory sleet]

More specifically a CompletableFuture is just a helper class to pass callbacks to said threads once they’re done with their work (they’ll run the callbacks)

[tardy delta]

mmmmh

sounds difficult

[ivory sleet]

Not at all

Have you messed with streams?

[tardy delta]

uhh no?

[ivory sleet]

Stream<T>

no?

[tardy delta]

wdym messed?

[ivory sleet]

Used them

In your code that is

[tardy delta]

well just .stream()

[ivory sleet]

Because streams also have a lot of similar methods to completablefuture

Main difference is that streams are for processing a sequence, whilst completablefuture process a single value with the help of your callbacks (usually on another thread)

[tardy delta]

mmh

and what is a callback?

i heard of it but i dunno exactly what it is

[solar sable]

damn theres so many error in this just hurts my brain tryna think

[ivory sleet]

Technically every method you declare is a callback

It’s a function which at some point later gets called back when some event happens

In async context it could be when a large computation is done

Or when a file is downloaded

Etc

[solar sable]

well this is a mess because i dont get this

[ivory sleet]

You sure don’t

new HoverEvent(...)

Forgot the new before HoverEvent(

And

That needs to be inside a method most likely

[solar sable]

hmm

by method you mean like?

[ivory sleet]

No

A method as the term in Java

?learnjava

[undone axle]

Here are some links to get you started on learning Java:

• https://www.codecademy.com/learn/learn-java
• https://www.sololearn.com/learning/1068
• https://www.learnjavaonline.org/
• https://programmingbydoing.com/
• https://docs.oracle.com/javase/tutorial/java/index.html

The last one is the only official one, however some of those concepts assume that you already know a bit about programming.

[ivory sleet]

I believe one of those sites cover it

Or in fact all of them

[hasty jackal]

I think you'd be hard pressed to find a resource for learning java that doesn't cover methods

[ivory sleet]

Yeah lol

[solar sable]

oh i managed to fix it a bit

but

there still an error in the player.spigot() and i changed from player to "e"

managed to do this

[ivory sleet]

I’m confused that it works

[solar sable]

im confused on what to change .spigot to

[ivory sleet]

e.getPlayer().spigot()

[solar sable]

fixed now?

wait i made it e.getPlayer().spigot().sendMessage(b);
will that work or no?

[quiet ice]

Does some random gradle fanboy know how to fix

[ivory sleet]

Send ur build script (:

[quiet ice]

https://github.com/cjburkey01/ClaimChunk/blob/main/build.gradle.kts
Just note that it was not written by me, otherwise I wouldn't be using gradle in the first place

[ivory sleet]

Understandable

[astral imp]

how do you hide the "No Effects" on a potion?

Is that an item flag?

[solar sable]

@ivory sleet

[hasty jackal]

unable to find valid certification path to requested target
that sounds more like a cert issue than a gradle issue. but the root cert I get should definitely be in the root store

[solar sable]

holy sh- @ivory sleet it works aaahh im screaming inside my self conscious!!

aaaahhh

[ivory sleet]

It’s so weird because the error seems to claim you’re trying to get annotations from some Apache repo when it’s on maven central

[quiet ice]

It is not a cert issue otherwise the java ecosystem would instantly break

[hasty jackal]

well it could also just be that one of the certs in your personal cert store got removed (for whatever reason), though obviously very unlikely

[quiet ice]

Firefox is able to download it without much issues directly, is gradle using a seperate cert store or something?

[hasty jackal]

most browsers have their own cert store, yes

[quiet ice]

RIP, in that case porting that mess over to maven would be my only solution

[hasty jackal]

the other alternative I could think of is that some caching issue was present and the wrong cert got served (like an ad-hoc self signed one)

I don't think that maven will make any difference; if it requests the same location of the library using the same java version, it would result in the same problem

unless it's a temporary issue

[quiet ice]

it could help that I'm using IntelliJ to build it - perhaps that is the issue

[solar sable]

anyone know how to put a player's name at the end of the line?

[quiet ice]

trying it out standalone, perhaps the most obvious thing is the thing to break

[hasty jackal]

I mean it does often run using it's own bundled JRE which might have that pooped cert store

[quiet ice]

yep, it's IntelliJ being broken. Guess a reinstall is all I can do

[ivory sleet]

oh rip lol

weird that issue never happened to me

[hasty jackal]

I guess it wasn't so unlikely after all heh

[ivory sleet]

geol using IntelliJ 😮

[quaint mantle]

Eclipse pfp
Uses intellij

eclipse is shit in everything

[quiet ice]

I'm kinda forced to when it comes to using kotlin gradle.

[ivory sleet]

fair

[quaint mantle]

it has like no good themes, the code completion is non existent

[solar sable]

someone?

[quiet ice]

Minimal code completion is best

[solar sable]

oh wait nvm

[quaint mantle]

you're high

[solar sable]

i think i already figured it out

[ivory sleet]

talking about code gen or code inspections?

[quiet ice]

Wat

[carmine nacelle]

are entity IDs persistent through reload/restart?

[ivory sleet]

nope

[carmine nacelle]

F

ok i have another way

[quaint mantle]

just use the UUID

[quiet ice]

Could not download commons-lang-2.6.jar (commons-lang:commons-lang:2.6)
Could not get resource 'https://papermc.io/repo/repository/maven-public/commons-lang/commons-lang/2.6/commons-lang-2.6.jar'.

papermc.io: Name or service not known

yep, IntelliJ is def. broken

[quaint mantle]

no gradle is that shit

[ivory sleet]

oh like
code inspections - finds issues in your code, for instance "turn anonymous functional interface instantiation into lambda"
code gen - when you press enter at the end of { it'd gen a }

[carmine nacelle]

is there a way I could like..."inject" data into a beehive's custom data? like if I wanted to keep track of how many bees the hive had and stuff

[ivory sleet]

oof

[quiet ice]

I mean, eclipse supports both :), and I quite like how it's done there

[ivory sleet]

havent used eclipse since the last blue moon so cant tell which one excels here

[quiet ice]

I was talking about stuff like auto-completing entire sections of code, i. e. "machine learning"

[ivory sleet]

oh

yeah those are often somewhat too aggressive imo

[quiet ice]

Okay, Imma try using raw ip addresses, let's see if intelliJ can handle that at least

[ivory sleet]

will be interesting

[native nexus]

It's hard to convince a person who has their pfp as the eclipse logo to switch to IntelliJ

[hasty jackal]

I mean you could try changing the boot runtime of intellij idea to fix it 🙃

[quiet ice]

At least some success there

declared mavenLocal, now it's down to a single depend that I'll likely have to build myself

[trail remnant]

am i doing something wrong? i followed the directions on the vault api page, i did https://pastebin.com/ZzKS75fz in my main class and in another class im doing main.getEconomy().depositPlayer(p, Double.parseDouble(args[1])); and im getting this error Caused by: java.lang.NullPointerException at com.abk.commands.economy.ecogive.onCommand(ecogive.java:119) ~[?:?] at org.bukkit.command.PluginCommand.execute(PluginCommand.java:45) ~[patched_1.16.5.jar:git-Paper-786]

[quiet ice]

main or main.getEconomy() is null. Please use Java 15 or higher for extended troubleshooting

[trail remnant]

.... i cant...

and how could they be null with my code?

[quiet ice]

they have to be

If you were using J15 it would be openly yelling at you what's null

Did you call #setupEconomy anyways?

[trail remnant]

yeah in the code i sent? thats everything that involves vault

[quiet ice]

You declare that method, yes, but you don't call it from the code you sent

[trail remnant]

wdym by "call"?

[eternal oxide]

line 3 you are returning true, it should be false

[quiet ice]

Invoke, run, whatever you call it

[carmine nacelle]

Whats the right way to stop the player interact event firing twice? if(event.getHand().equals(EnumWrappers.Hand.OFF_HAND)) return; doesnt seem to be working

[trail remnant]

invoke run...? what

[quiet ice]

Do you have something like myPluginInstance.setupEconomy()?

[trail remnant]

uh no

[quaint mantle]

thats why

its never called

hence its null

[quiet ice]

well, it's needed otherwise econ will stay uninitalized

[trail remnant]

but dont i just call it from my command? main.getEconomy().depositPlayer(p, Double.parseDouble(args[1]));

[quiet ice]

no, you call getEconomy() with will just return econ

as such you can just short-circuit it with main.econ.depositPlayer(p, Double.parseDouble(args[1]));

if econ is never set to a value, it will be null, thus throwing a NullPointerException

[trail remnant]

i did what you sent and in intellij it just shows up in red with no context

[quiet ice]

That's because it's likely not valid code and I just made it to simplify it for you

You should be doing it the way you did it before, but initalize econ properly

[ashen flicker]

Make sure you either A have a static instance of main that you’re using, or B, you’re properly passing around the main instance. If you do that, and the economy is already set up. You should be fine.

[trail remnant]

i already do if this is what you mean private static Economy econ = null;

[quiet ice]

I'm assuming it is the private modifier

Sigh

[wicked fulcrum]

guys can i use always static or its bad?

[ashen flicker]

That doesn’t need to be static if your main instance is

[quaint mantle]

its bad to use all the time

[quiet ice]

Just add setupEconomy(); at the top of your onEnable()

[solar sable]

i need help

[quaint mantle]

print the name

player.getName()

[quiet ice]

don't invoke .toString() use .getName()

[quaint mantle]

use == for enums!!

[ashen flicker]

Static isn’t always bad, it had a purpose other wise it wouldn’t exist. It’s good for functional programming, not everything has to be OO.

[quaint mantle]

idk what you're on about imma simplify this
in main @trail remnant

// onEnable method
this.setupEconomy();

Command

private final MyPlugin plugin;

public MyCommand(MyPlugin plugin) {
    this.plugin = plugin;
}

// Command method
plugin.getEconomy().// whatever

[quiet ice]

^

[trail remnant]

ok ill try it thanks

[ivory sleet]

we got the singleton pattern also and true constant 😄

[quaint mantle]

Why transfer the plugin every time? better convey the Economy right away

[carmine nacelle]

lol cannot be applied to equipment slot.

[quaint mantle]

what if you wanna reload the config

[quiet ice]

because you'll use the plugin instance for other reasons

[quaint mantle]

also that

[quaint mantle]

if (event.getHand() == EquipmentSlot.OFF_HAND)

[solar sable]

it only gives me e.getPlayer()

[quaint mantle]

e.getPlayer().getName()

[quaint mantle]

I'm using custom config class for that

[solar sable]

oh wow that was easy to fix

Thanks to all of you! <3

[ashen flicker]

Yea I use the singleton pattern in my plugins. I like it

[quaint mantle]

I transfer the Config||.java|| to the class, and then I work with this class, it already has a built-in method for reloading the config, as well as receiving messages from it

[trail remnant]

all i did was add what you said this.setupEconomy(); and i tried to use plugin.getEconomy() but intellij auto corrected back to what i originally had, main.getEconomy() and it still isnt working, same errors
