No spaces

Recommended

[wary topaz]

NamespacedKey key = new NamespacedKey(this, "Revive Token")
ShapedRecipe recipe = new ShapedRecipe(key, reviveToken());

oh

[lost matrix]

The namespace is your plugin and the key is something you imagined.
It has to be all lower case and can not contain spaces

[regal scaffold]

But close

[wary topaz]

ReviveToken

revivetoken

[quasi flint]

Doesnt it replace spaces?

[regal scaffold]

I'm actually not sure if it does

[wary topaz]

i think it errors

[regal scaffold]

bUT

[lost matrix]

NamespacedKey key = new NamespacedKey(yourPluginInstance, "revive-token");

[regal scaffold]

There's a correct case for it

There

fk u smile

0-2

[wet breach]

Possibly but better to not rely on it

[wary topaz]

Cannot resolve constructor 'NamespacedKey(everything, String)'

[regal scaffold]

Impor

[lost matrix]

[wary topaz]

        ShapedRecipe recipe = new ShapedRecipe(key,reviveToken());```

[regal scaffold]

t

[wary topaz]

the reviveToken is the itemstack

dw bout htat

[regal scaffold]

Did you import?

[lost matrix]

This would only work while you are inside your JavaPlugin class.

[wary topaz]

Ah

[quasi flint]

It needs the instance

Of your plugin

[lost matrix]

But dont just put this in your JavaPlugin class pls

[quasi flint]

To Register the namespace to

[regal scaffold]

xd

[wet breach]

Keyword this refers to the class the method is currently in

[wary topaz]

NamespacedKey key = new NamespacedKey(plugin,"revivetoken");

plugin is standed for the main class

[regal scaffold]

There you go

[wary topaz]

injection

[regal scaffold]

Except for

revive-token

[wary topaz]

yay me learning

[quasi flint]

I will do it and i will fucking so it again

[regal scaffold]

wat

[wary topaz]

ill load it

[regal scaffold]

smile

I'm gonna buy this 9 buck course lol for the memes

You wanna take a look at it?

[wet breach]

No

[wary topaz]

no errors

[regal scaffold]

Check console

[wary topaz]

ill show full file

[regal scaffold]

remember when we specifically said

[wary topaz]

not 45

44

[regal scaffold]

"don't just put this in your main class plz"

xd

[wary topaz]

its not my main class

[regal scaffold]

Oh yeah

[wary topaz]

import SpeedSMP.everything.everything;
import org.bukkit.event.Listener;
import org.bukkit.plugin.java.JavaPlugin;

public final class Main extends JavaPlugin implements Listener{

    @Override
    public void onEnable() {

        saveDefaultConfig();
        new everything(this);

        // Plugin shutdown logic
    }
}

this is my main class

and dw about main name

[regal scaffold]

lol

[wary topaz]

ill fix later

[regal scaffold]

Ok I want to clarify ethan

When people say

Don't put eveything in your main class

They mean, split stuff into different files

Not make a new file and put everything there

[wary topaz]

this plugin is made for 1 person

[lost matrix]

This section would be interesting as im planning on releasing my first premium resource soon

[regal scaffold]

Just for the future

[wary topaz]

it doesnt matter

but koay

thanks for the advice lol

[wet breach]

I mean really depends on how large plugin is. If its just only for a custom item or recipe then it wont hurt anything as plugin isnt large amyways lol

[wary topaz]

its like a lifesteal plugin but instead of hearts its speed

[regal scaffold]

Where is that one from

What category

[lost matrix]

Final Advice

[regal scaffold]

Oh the last one

It's lit 9 bucks I got you

[wary topaz]

and yes for the authors im putting #help-development

lmfao

[lost matrix]

dont fret

[regal scaffold]

I wanna give it a look too

[wary topaz]

but any idea why it aint working?

[regal scaffold]

I have a plugin that does that 1 sec ethan

[wet breach]

Best advice for managing sales. Dont ignore your clients and learn paypal policies in regards to chargebacks which will help you to respond to them and not have paypal side with consumer

[wary topaz]

alr (no ping)

also i know this may be basic java but everything i tried aint fixing this

[regal scaffold]

    private void unregisterCrafting() {
        Iterator<Recipe> iter = Bukkit.recipeIterator();
        while (iter.hasNext()) {
            Recipe recipe = iter.next();
            if (recipe.getResult().getType() == Material.COPPER_BLOCK) {
                NamespacedKey key = new NamespacedKey(this, "copper_block");
                ItemStack copperBlock = new ItemStack(Material.WAXED_COPPER_BLOCK);
                ShapedRecipe copperBlockRecipe = new ShapedRecipe(key, copperBlock);
                copperBlockRecipe.shape("CCC", "CCC", "CCC");
                copperBlockRecipe.setIngredient('C', Material.COPPER_INGOT);
                Bukkit.addRecipe(copperBlockRecipe);
                iter.remove();
            }
            if (recipe.getResult().getType().name().contains("BED")) {
                iter.remove();
            }
        }
    }

[wary topaz]

i only want 1 decimal point

oo ill look at that

[regal scaffold]

I did that when I wanted to remove some recipes

And add a new one

                NamespacedKey key = new NamespacedKey(this, "copper_block");
                ItemStack copperBlock = new ItemStack(Material.WAXED_COPPER_BLOCK);
                ShapedRecipe copperBlockRecipe = new ShapedRecipe(key, copperBlock);
                copperBlockRecipe.shape("CCC", "CCC", "CCC");
                copperBlockRecipe.setIngredient('C', Material.COPPER_INGOT);
                Bukkit.addRecipe(copperBlockRecipe);

[wary topaz]

I dont see anything different to this than mine

[regal scaffold]

new RecipeChoice.ExactChoice(speedCapsule())

What is that

[wary topaz]

ill get the line number

113

[regal scaffold]

I know what the line is. What is it

[wary topaz]

when drank

gives

0.05 speed

[regal scaffold]

That a custom item?

[wary topaz]

yse

kindof

[regal scaffold]

You're gonna need someone with more experience to help you then

[wary topaz]

line 130

[regal scaffold]

Wait for smile or frost

[wary topaz]

okay

hope i dont have to use nms lol

[wet breach]

What we doing?

[lost matrix]

Was about to ask

[regal scaffold]

Crafting recipe with custom item

        NamespacedKey key = new NamespacedKey(plugin,"revivetoken");
        ShapedRecipe recipe = new ShapedRecipe(key,reviveToken());
        recipe.shape("ABA","B B","ABA");

        recipe.setIngredient('A',new RecipeChoice.ExactChoice(speedCapsule()));
        recipe.setIngredient('B',Material.DIAMOND);

line 5

[wet breach]

Nothing to it other then replacing output with custom item instead

[lost matrix]

No you dont

[regal scaffold]

That didn't work tho

[wary topaz]

the output is also a custom item

and one of the inputs is

they are all itemstacks besides the diamond

[lost matrix]

Some more code pls

[wary topaz]

thats all the code

[lost matrix]

The code on top looks right

[regal scaffold]

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

That's his class

[lost matrix]

Ah i see

[regal scaffold]

Smile do you only want the plugin licensing

Or the entire final advice

[wet breach]

Pretty sure they know plugin licensing lol

[regal scaffold]

Forst we understand. We're just evaluating how it looks

If you don't need it I won't send it to you

[wet breach]

I would be surprised with someone like 7smile7 knowing what they do and not know licensing lmao

[regal scaffold]

But there's about 19 hours of videos

In this course

[vocal cloud]

Most of it is self evident stuff

[lost matrix]

Alright the registering looks fine. Do you have any exceptions in your console (When the plugin enables for example)

[wet breach]

Except the stuff that comes out of nowhere

[wary topaz]

I'll reload again.

[lost matrix]

Never reload

[wary topaz]

Nope.

[lost matrix]

Never

[regal scaffold]

.

[wary topaz]

?

[vocal cloud]

Like how to use JSON

[wary topaz]

i'll restart;-;

[lost matrix]

always restart

[wary topaz]

takes a while loll

no errors

[lost matrix]

Uhm ive watched the preview. Nothing too interesting there

[regal scaffold]

Alright boys I'm heading to bed. 4am. Have a good one see you tomororw

[lost matrix]

ok so when you check if your plugin is enabled /pl its there and its green

[wary topaz]

green

[wet breach]

Maybe i should make my own udemy course for jvm intricacies and how it can relate to your code

[regal scaffold]

Make an advanced one

[vocal cloud]

Ikr look how many sales that one has

It's just teaching you basic java under the guise of Spigot

[regal scaffold]

Making a course that big is still very time consming

It's over 18 hours of 1080p video

[vocal cloud]

Quality > Quantity

[wary topaz]

Quandaledingle

[vocal cloud]

I 100% bet you I could make a wiki that would have less quantity but 100% more quality. It's of course easier and better to just sell this stuff

[lost matrix]

Use sticks instead of your custom items and try the recipe again

[wary topaz]

aight

[wet breach]

Like for instance the amount of objects in a class or the size of objects cab cause your class to not be inside heap space and instead fragmented between heap and some other slower memory space and this be the source of your lag or why your code isnt performing as expected. There is only two ways to fix this. From user side increase object space per thread which means more ram consumed on thread generation or restructure your code to not have this happen

[wary topaz]

recipe.setIngredient('A',Material.STICK);
recipe.setIngredient('B',Material.DIAMOND);

[lost matrix]

Question is: What is the target group for such a course

[halcyon hemlock]

wsg guys

[vocal cloud]

I'm listening

[wet breach]

Ideally someone like you really

[lost matrix]

You sure

[wet breach]

Where you already pretty versed but just not might be aware of some things like that

[wary topaz]

no errors

ill try changing the recipe

[halcyon hemlock]

Custom recipes huh

[wary topaz]

yep

[halcyon hemlock]

123
456
789

[lost matrix]

Did you actually compile and copy your newly compiled plugin in your plugins folder?

[wary topaz]

yes

[lost matrix]

Change the result item to a simple vanilla item as well then

[wary topaz]

alr

let me make a vanilla itemstack

[halcyon hemlock]

try logging someone on onEnable()

make sure

[lost matrix]

My guy the sticks need to be in the corner

[wary topaz]

@halcyon hemlock wdym

[wet breach]

You seem pretty well versed in regards to java coding wise then most. And only thing i could recommend for such people is learning jvm things that adversely affects your code but isnt really widely known or isnt really a easily searchable thing to learn unless you knew something beforw hand

[regal scaffold]

XD

[wary topaz]

omg

[halcyon hemlock]

LMAO

[wary topaz]

it worked

[regal scaffold]

XD

[wary topaz]

but it didnt owkr for the otehr one

[vocal cloud]

Drunk science over here

[wary topaz]

the other custom item

[halcyon hemlock]

ABA
B B
ABA

[halcyon hemlock]

fr

[wary topaz]

new RecipeChoice.ExactChoice(speedCapsule()) seems to not work

and yes i did the right placement

[lost matrix]

Clear your inventory and give yourself a new clean capsule

[wary topaz]

yes sir

[wet breach]

What i explained is one example of a niche thing most wont really know. The other thing is, is nulling out objects you dont need anymore

[lost matrix]

Do they stack?

[wet breach]

While in general everhthing says it isnt required they are correct but it doesnt mean you shouldnt do it either

[wary topaz]

they odnt

but i dont check the nbt

i check if unbreakable

soany food thats unbreakable

is yk

[wet breach]

The main reason for nulling out objects you know you wont use again or are just done with is it lets the gc work faster

[lost matrix]

?

[wary topaz]

cause i add the number every time

its set in config.yml

because

i dont want it to stack

[lost matrix]

RecipeChoice.ExactChoice checks the whole nbt component

[wary topaz]

and theres no .setStackable

wait

WAIT

let me try something

[wet breach]

Instead of the gc trying to figure if it should or shouldnt gc something nulling out your objects just saves time on the gc doing that

[wary topaz]

how can I make a item not stackable than?

[wet breach]

Make it unique

[wary topaz]

yes

but it checks

for exact nbt

[lost matrix]

If the nbt data does not match 100% then the recipe doesnt work

[wary topaz]

^

so how can I detect

with my settings

or should I just figure out how to make it unstackable

and revert my progresws

and someone said to do that I need nms

wait what?

[wet breach]

You might be progressing into the area where you have to implement your own recipe stuff. Like instead of the server validating the recipe for you. You would do that yourself. Which requires more work on your part

[wary topaz]

wdym

[lost matrix]

This is a very intricate problem.
You have 2 choices:

1. Write a custom crafting system which checks for specific item
   properties. (Pretty complicated)
2. Fetch the outgoing ItemStack packets and add lore lines in them (Very complicated)

[wary topaz]

@quaint mantle you say I can make it unstackable easily?

which could solve everything?

[lost matrix]

Remove the lore line and check if the recipe works (it should)

[wet breach]

You can listen for crafting inputs and validate yourself if what was put in is correct. You dont have to use the api for that. The advantage is you can basically use any item even if they dont match exactly because you said it is allowed

[wary topaz]

The problom with it being stackable is it takes the entire thing when consumed

[wet breach]

The disasvantage is a lot more code lol

[wary topaz]

I tried that

it just didnt do anything

[lost matrix]

Try harder 😄

[wary topaz]

yes sir

[wet breach]

Manually place back in their inventory the amounts that were unnecessary

[lost matrix]

That one is not too complicated actually. You just need to find out when to cancel the event and when to manually subtract items.

[wet breach]

If you can obtain the count and item, then you know how many needs to go back in their invebtory

[lost matrix]

Cancelling the consume event and decrementing the consumed item should work as well

[wary topaz]

i cancelled it before

[wet breach]

Yeah that works too

[wary topaz]

but icant subtract

[wet breach]

The way i explained doesnt require cancelling anything

So use which ever way you prefer

[wary topaz]

p.getinventory().remove(speedcapsule, (event.getItem().getAmount() -1))

[wet breach]

Instead of removing add

[wary topaz]

add

whoa

[lost matrix]

ItemStack item = event.getItem()
item.setAmount(item.getAmount() - 1)

something like that

[wary topaz]

ill be back when I finish

[wet breach]

Let the items get consumed keep track of what they had or what was required and instead you add to the onventory

For the way i am talking about

[wary topaz]

you cant add or remove a specific amount?

[lost matrix]

Well this could result in the item being added at the beginning of the Inventory

[lost matrix]

You just want to remove 1 of the consumed item, right?

[wary topaz]

yse

[wet breach]

You can add however many items you want to their inventory given they have space for it

I am aware

[wary topaz]

hehe

yes but the add doesnt have a int?

[lost matrix]

Then i would strongly recommend this:

  @EventHandler
  public void onConsumer(PlayerItemConsumeEvent event) {
    event.setCancelled(true);
    ItemStack consumedItem = event.getItem();
    consumedItem.setAmount(consumedItem.getAmount() - 1);
  }

[wary topaz]

setamount!

thats what I needed!

loading the plugin

0 warnings

[wet breach]

My way i explained to use an analogy is if you owe me $10. But instead you gave me $20. All i have to do is give you $10 back. I didnt subtract anything because you gave me all what you had. If that makes sense. So in regards to what i was saying. If all the items are being consumed just allow it, but you return however many was too much. This isnt really subtraction per say lol

[wary topaz]

uhh it did not take the item

[lost matrix]

This one is also viable but you cant target a specific ItemStack in your inv. Besides that, the result is the same

  @EventHandler
  public void onConsumer(PlayerItemConsumeEvent event) {
    event.setCancelled(true);
    ItemStack consumedItem = event.getItem();
    ItemStack removalItem = consumedItem.clone();
    removalItem.setAmount(1);
    event.getPlayer().getInventory().remove(removalItem);
  }

[lost matrix]

Im getting memory mapped files vibes from you... Are you the mem mapped files guy?

[wary topaz]

https://paste.md-5.net/ojeterafan.java no errors just not taking item

[wet breach]

Yes i am

[lost matrix]

😄

[lost matrix]

Didnt work?

[wary topaz]

nope

[wary topaz]

e

and yes ill remove the % after this

[lost matrix]

What version are you on? This only works for 1.14+ iirc

[wary topaz]

latest

[wet breach]

Add some debug messages

[wary topaz]

alr

[wet breach]

So you know what is or isnt being executed

Peecisely

[wary topaz]

 event.setCancelled(true);
            event.getItem().setAmount(event.getItem().getAmount() - 1);
            p.sendMessage("u hungy?");

[lost matrix]

Well the message after the removal line gets sent so something is weird here

[wary topaz]

im guessing he aint hungy

[wet breach]

Lol

[lost matrix]

Hm... Delay it by one tick

[quaint mantle]

hi

[wary topaz]

uhh you mean like scheduler?

[quaint mantle]

im beginner programmer

[wary topaz]

hi

welcome to paridise

no errors ever

[wet breach]

You could also just manually consume the item too

[wary topaz]

the problom with taht

the glass

glass bottle

[lost matrix]

Spigot is not an incredibly good place to learn java

[wet breach]

You dont want the glass bottle or yoy do?

[quaint mantle]

good place to fix errors

[wary topaz]

I dont

[lost matrix]

Bukkit.getScheduler().runTask(plugin, () -> consumedItem.setAmount(consumedItem.getAmount() - 1));

[wary topaz]

precious we dnot spoonfeed

[wet breach]

You cancel the event then and then remove item and apply effects

[wary topaz]

7smile did you delay?

doesnt look like you did

[lost matrix]

Yes this delays by one tick

[wary topaz]

oh

[quaint mantle]

what's spoonfeed?

[wary topaz]

default?

[wet breach]

?spoon

[undone axle]

Spoonfeed a newbie for a day and they'll come back with more questions. Teach them to find their own answers and you'll both be better off: you won't get stuck answering the easy questions and they'll be much more productive than before.

[lost matrix]

Yes tasks run earliest at the next tick

[wary topaz]

nope

[wet breach]

Couldnt you just manually do it? Lol

[lost matrix]

Let me try it out myself...

[wary topaz]

frost but what if the player has glass bottles already in their inv?

7smile need the main class again?

[wet breach]

Cancelling the event stops it

[wary topaz]

but wdym manually than?

[wet breach]

So what you do is cancel the event when they drink potion. It doesnt stop the animation but it does stop the glass bottle problem

[wary topaz]

but than they dont drink it?

it just loops

its like lag but intentional

[wet breach]

After cancelling you remove potion from inventory and then you apply the effects it is suppose to have

[wary topaz]

what if it's in their offhand?

how would I know what to remove?

[wet breach]

You can detect that because its still inventory

[wary topaz]

what if they have multible :hehe:

[wet breach]

Just because you cancel the event doesnt mean you cant use the event to get what is in their hand

Event doesnt stop being useful just because you invoked cancel

[wary topaz]

But how would the event know what to remove if we cancel?

7smile you almost done with that test?

[wet breach]

Because you use it to get where item is at and then you use inventory api or player api to remove the item from the proper slot

[wary topaz]

And the exact amount?

[wet breach]

Sure

[wary topaz]

What api should I use

or they same

[wet breach]

Probably inventory api as it would have the methods you are in need of including subtracting and removinf

[wary topaz]

^

[lost matrix]

This works

  @EventHandler
  public void onConsumer(PlayerItemConsumeEvent event) {
    event.setCancelled(true);
    ItemStack equippedItem = event.getPlayer().getInventory().getItem(event.getHand());
    equippedItem.setAmount(equippedItem.getAmount() - 1);
  }

[wary topaz]

alr gimmie a min

wait

try honey bottles

or did you edit the code

[lost matrix]

Honey works as well

[wet breach]

7smile7 gave you the code

[wary topaz]

😮

[wet breach]

I am at work currently and on a phone lol

So hard to just do up some code

[lost matrix]

What are you working and why do you have so much spigot time 😄

[wary topaz]

Method invocation 'setAmount' may produce 'NullPointerException'
would you be mad if I put not null 🙂

[wet breach]

I am a tire technician

[lost matrix]

Do a null check

[wary topaz]

its just nullable

[wet breach]

And i work for jbhunt and i dont habe much work tonight lmao

[wary topaz]

It worked!

[wet breach]

Dont use notnull for things that can become null outside of your control

[wary topaz]

Ah

yeah I hate memory leaks

[wet breach]

Its not a memory leak

[wary topaz]

wait what?

[wet breach]

It will throw errors if it is bull but hide that it is because something else made it null

[wary topaz]

but a player can just spam it and it could clog the server/

ohh

[lost matrix]

Noice. But thats pretty far away from programming, right? Did you consider getting a software dev job
or do you not want to mix hobby and work.

[wary topaz]

ima try to find some bugs

[wet breach]

Notnull is for if you ensured it cant be null and if it is something very terrible happened in the jvm and we should just stop anyways

[wary topaz]

like assert?

i feel they are the same thing lol

assert & not null

[wet breach]

Assert is kind of the same but slightly different. Both have differing uses where they are supposed to be used

[wary topaz]

ah

well tysm for the help!

you deserve discord helper role

you too 7smile7'

its 2 41 here so i'm gonna call it a day

have a good one

[wet breach]

I dont want to lose my hobby. Also i dont like the idea of working in a place where i dont have freedom or working under some leadership that fails to understand

So i stick to freelancing

I have had some decent freelance jobs before. I at one point sub contracted with phoenixNAP

For their customers where their contract prevented them from providing support

[lost matrix]

oof

[wet breach]

So like ovh for example. Servers are cheap because no software support

[wary topaz]

ah shoot we back at it again I was doing a bug check and

[wet breach]

Many dont know os is still software so it includes that too

[lost matrix]

Thats the normal minecraft behavior. Fixing this can be a bit complicated.

[regal scaffold]

Bro you guys are still going with the crafting stuff

[wet breach]

Well phoenixnap had contracts like that, and where i came in is instead of their customer support saying we cant help they referred their customers to me instead

[wary topaz]

tomisan spigot is for nolifers only

[wet breach]

And i got to charge my own rates

[lost matrix]

well im off to the gym now, see ya guys

[wary topaz]

cya

[wet breach]

Cya later

[wary topaz]

yk what i dont care if theres glass bottles in the crafting grid

no plugin is perfect

[wet breach]

Lol

I will be home in like 5 hours 🙂

[wary topaz]

AND IM BACK AGAIN 😉

the the revive token

it can craft becaons

beacons

how can I make it specificly NOT craft beacons

(im addicted to spigot)

the way you can tell this is a revive token is because of the unbreakable tag

ping me while im sleeping

idc

[tall dragon]

cancel CraftItemEvent when the crafting inventory contains ur custom item i guess

[tender shard]

intelliJ drunk? how does List<T> clash with List<T>

[tall dragon]

u gotta make it return List<Invention>

[tender shard]

yeah

what is the difference between List<Invention> and List<Invention>

[wet breach]

Its most complaining of your return type

[hybrid spoke]

type erasure

[tender shard]

guys

[hybrid spoke]

so you gotta be explicit

[tender shard]

I got an interface that declares getInventions() returns List<Invention>

so how can the above thing be wrong lol

[wet breach]

I cant see what you are returning

Its hidden by that big message

[hybrid spoke]

List.of doesnt return List<Invention>

at least not in the first place

type erasure fucks things up just like this

so your return has to be explicit or your class generic

[wet breach]

In order for a method to be a valid overiddeb method you have to return the same kind of object as well

Otherwise if you dont you get a method clash from your inplements

Godcipher knows what they are talking about and my phone is just hating me with all these spelling mistakes

Think i need to recalibrate the touch lmao

[tender shard]

You are both confused, if the method body would be the problem, intellij wouldn place the red underlinings there instead of under the method return type

Btw File -> Invalidate Caches fixed it

[wet breach]

Well i couldnt see what you were returning

I stated as such

A big box over your method isnt helpful sometimes lol

[hybrid spoke]

and still is that one of the annoying issues with generics

[tender shard]

but why would it matter

[hybrid spoke]

you were asking why it complains if both are the same

we couldnt see it

"trust me bro"

[tender shard]

if intellij already complains about the red part, the green part is completely irrelevant

it complained that "List<Invention>" is not the same as "List<Invention>" declared in the "Inventor" interface, although it was

[hybrid spoke]

then i understood that wrong

[regal scaffold]

If I have an event that's getting called twice each time when it shouldn't

[hybrid spoke]

but what kind of plugin will this be

InventorOfTheWalkieTalkie

[regal scaffold]

How can I make my eventlistener pause for less than a second so the second one doesn't do anything

[hybrid spoke]

what event is it

[regal scaffold]

Dumb third party event

DonationReceivedEvent1

From crafting store

Getting called twice identically each time

[jagged monolith]

https://github.com/dmulloy2/ProtocolLib/#using-protocollib

[hybrid spoke]

you could take a look at https://github.com/GodCipher/Anti-AutoClicker/blob/master/src/main/java/dev/luzifer/antiac/listener/Listeners.java#L280

had the same problem there

that fixed it

[tender shard]

it's not a plugin, I tried to turn a simpsons episode into some code lol. and they were talking about the inventor of the walkie talkie and were confused because he attended a convention with a girl who's not his wife

[regal scaffold]

Not a player tho

I mean I guess I can attach it to a player

Aren't events processed async?

[tender shard]

just cancel the CraftItemEvent if any of the items in your crafting matrix is your custom item.

    public boolean isMyItem(@Nullable ItemStack item) {
        if(item == null) return false;
        if(item.getType() != Material.NETHER_STAR);
        if(!item.hasItemMeta()) return false;
        ItemMeta meta = item.getItemMeta();
        return meta.isUnbreakable();
    }
    
    @EventHandler
    public void onCraft(CraftItemEvent event) {
        for(ItemStack item : event.getInventory().getMatrix()) {
            if(isMyItem(item)) {
                event.setCancelled(true);
                return;
            }
        }
    }

[hybrid spoke]

not your exact solution, just an example

[regal scaffold]

Yeah I just noticed for a second I thought it was a spigot method

[wet breach]

Because you have to return same object type as the super does otherwise its not a method you are overriding. I was going based on what godcipher said as i assumed they knew what it was you were returning. Sometimes not important in what exactly the message says but what the code looks like and i just couldnt see that because of you big message box

[hybrid spoke]

only those which are supposed to be

[tender shard]

by giving the correct groupid, artifactid and version

[regal scaffold]

What if I make this event run in a separate thread and pause it for 10 ticks

[wet breach]

Not all of them

[tender shard]

and List<Invention> is not the same as List<Invention> or what

[regal scaffold]

Whatever I'll just use the `triggeredRecently

[tender shard]

obviously it is the same as the super class, that is even written in the message I sent

[wet breach]

I couldnt see the return type specifically. Just because the ide tells you something doesnt mean it wont compile

[tender shard]

the quick fix suggests me to use "List<Invention>" instead of "List<Invention>", so it's quite obvious that it's the correct return type

[wet breach]

Ides are not always smart

[tender shard]

yeah

intellij actually seems to be stupid quite often

[hybrid spoke]

couldve also been an import issue ¯_(ツ)_/¯

[tender shard]

but it wasnt

[wet breach]

All i am saying is i just couldnt see your code exactly is all. I trust what i see from the code not what the ide wants to tell me lmao

[hybrid spoke]

anyways guys topic is over

next

[wet breach]

Indeed

In other news its boring tonight at my work

Like 2 trucks out of 200 needed tires

Still have 3.5 hours left of work

[tall dragon]

so ur out of work? haha

[wet breach]

Well no, there is trailers but trailers are not todays schedule

Those are tomorrow

[tall dragon]

cant u just work ahead then?

[wet breach]

In a way i guess this js true. Ironic really

[wet breach]

Yes but tomorrow the trailers out there may not be the same ones for tomorrow

[tall dragon]

ah right

[wet breach]

And i rather not bring a trailer in for tires and then turns out it needs 10 other things done

[tall dragon]

yea where i work we dont get that haha

there is always work

at least i have not yet found a day where i had nothing to do in the 3 years ive worked here

[wet breach]

Doesnt help i have a crap ton of truck tires right now with no trucks to put them on lmao

Tire container is full so i have like 5 stacks of tires just sitting in the tire bay because no where to put them

[tender shard]

time to annoy myself again:

[wet breach]

I have approximately 200 truck tires and 100 or so trailer tires

[tall dragon]

Thatsss alot of tires

[wet breach]

Trailer tires will get used up quick bit with no trucks needing tires its going to take like a week of waiting for trucks needing tires

[tender shard]

fuck obs

[regal scaffold]

btw yes I'm aware this is spigot but how does this look

https://docs.papermc.io/paper/dev/getting-started/paper-plugins

[remote swallow]

Its dumb

[regal scaffold]

Isn't that like if you "forked" paper but easier?

[remote swallow]

It broke q load of spigot plugins

[tender shard]

is it normal that the "update dependencies" button in intellij doesn't do anything when using gradle?

[regal scaffold]

Alex it's like day 3 of these gradle issues

I think gradle knows you're the maven master and doesn't want to work with you

[tender shard]

I convert a different project every day

none of which has properly worked so far, though

[regal scaffold]

Somehow gradle gives you issues every day lol

And somehow, different issues. which is crazy

[tender shard]

not only me, everyone got the same stupid issues. however this is an intellij problem

[regal scaffold]

this why maven good

[tender shard]

obviously maven is better

[regal scaffold]

ebic would disagree

[tender shard]

oh he actually knows it's true, after all he probably knows how much hours he wasted converting maven projects to gradle, probably taken him 5 hours of his time, while saving 37 seconds

[regal scaffold]

It'll pay off in around...

2 years

[tender shard]

not even then, gradle has meanwhile received an upgrade and now your build.gradle isn't compatible anymore

[regal scaffold]

What project you working on rn alex

[tender shard]

MorePersistentDataTypes

[regal scaffold]

What you adding to it

[tender shard]

a build.gradle lol

[regal scaffold]

bruh lol

[tender shard]

unfortunately gradle init always gets rid of the proper repo to publish to

[remote swallow]

Give me like 6 days and ill pr it

[tender shard]

I have added it like in their docs, but the task doesnt even exist

https://docs.gradle.org/current/dsl/org.gradle.api.publish.maven.tasks.PublishToMavenRepository.html

[remote swallow]

Your missing the other publication stuff, and login

[tender shard]

what other publication stuff? that's exactly how the docs describe it, see here: https://docs.gradle.org/current/userguide/publishing_maven.html

[remote swallow]

Look at epic spigot lib or better item config

[tender shard]

EpicPluginLib doesnt declare any publishing stuff

but it also wouldnt be needed since it uses maven

and EpicSpigotLib, i didnt find anywhere

what the fucking hell

ALL OF THIS is required to make gradle upload a tiny .jar?

lol

[remote swallow]

That is for 2 repos

[tender shard]

however how is this different from what I sent? except that you also declared the username / password

[remote swallow]

It has the shadow(MavenPublush)...

[tender shard]

I do not want to publish any shadow stuff

just the normal .jar that gradle outputs

[remote swallow]

So get the non shadow stuff from maven publish

[tender shard]

I did

[tender shard]

here

just like the docs say

[tender shard]

here

[remote swallow]

You need the publish stuff

Ill go find

[tender shard]

it is here

the publishing { } section

[remote swallow]

Dont need version, groupid or artifact id

Then put the maven section under the from components.java

[tender shard]

where is that from?

[remote swallow]

Googling maven publish and opening the first pink

Link

[tender shard]

cant you just send the actual link pls lol

[tender shard]

because when I google "maven publish" it obviously doesnt show any gradle stuff

[remote swallow]

https://docs.gradle.org/current/userguide/publishing_maven.html

[tender shard]

but according to the docs, the exact you send is only there to override group id, artifact id etc

which I don't want to

[remote swallow]

You dont need that

Like I said

YOu need the rest of the stuff

[tender shard]

still doesnt work

[remote swallow]

Just call punlish

Publish

[tender shard]

I get it that I could get it to work by using random other task names, but why can't I use the names that are explained in the docs? https://docs.gradle.org/current/dsl/org.gradle.api.publish.maven.tasks.PublishToMavenRepository.html

[remote swallow]

Use publish and see if it works

[tender shard]

like, if the docs call it "PublishToMavenRepository" and the actual name is "publish", then "build" could as well be "eatDogShit"

nope:

[remote swallow]

If it doesnt leave gradle alone and ill pr it when im home

[tender shard]

Execution failed for task ':publishMavenPublicationToJeff-media-publicRepository'.
> Cannot convert URL 'https://hub.jeff-media.com/nexus/repository/jeff-media-public/' to a file.

* Try:

> Run with --scan to get full insights.

that's when I do "gradlew publish"

[remote swallow]

Ill pr it when im home, in the mean time stop trying to convert gradle

[tender shard]

why? I am doing everything exactly as explained in the docs

[remote swallow]

The docs are wrong most of the time

[tender shard]

lmao

what a great piece of software 👍

[wet breach]

I understand what alex is saying lol

Basically they dont like the semantics of it

[tender shard]

i dont like the general idea of "you always just gotta copy/paste from someone else because the official docs are always wrong"

[wet breach]

Which i can agree. But both me and alex though are accustomed to mave and love the verbosity of it that makes it clear

[tender shard]

like, how is one supposed to know that it has to look like this:

while the docs state sth completely different

[rocky tree]

ItemStack item = new ItemStack(Material.BOOK);
ItemMeta oM = item.getItemMeta();
ItemStack iM = new ItemStack(player.getItemInHand());
if (iM.getItemMeta().getDisplayName().equals(oM.getDisplayName())) {
...
} else {
....
}

It is always false, anyone?

[tender shard]

it's only false if the display names don't match

o0

[rocky tree]

Yeah, but the name is the same

[tender shard]

btw you should not use weird variable names like iM or oM

[wet breach]

Probably if you are not accounting that displayname can have colorcodes

[tender shard]

print out the name

[rocky tree]

K, I try

[wet breach]

There is another method you can use to get the name that doesnt include color codes

[regal scaffold]

There aren't that many good ways to compare if the item is a custom item

It's a bit annoying tbh

[hybrid spoke]

pdc

simply the best way

[regal scaffold]

Well yeah I know but not that many more options

Names, pdc, what else

[tender shard]

yeah, comparing items by name is always a bad idea

[hybrid spoke]

lores, nbt tags

[rocky tree]

Ok work, I'd fix.
Ty

[tender shard]

PDC is the only proper solution

[wet breach]

Or just compare item objects and not strings

[hybrid spoke]

#isSimilar also an option

[regal scaffold]

That'll apply to any item of the same no?

[wet breach]

No

[tall dragon]

if (iM.getItemMeta().getDisplayName().equals("Hi")) {
...
} else {
....
}

why create another itemstack only to use its name.. just input a string like above

[tender shard]

why check the name of the item in the first place?

[wet breach]

That wasnt what i meant lol and i was going to say it does matter what it is you are doing that dictates which might be more ideal

[tall dragon]

yea debatable. but just tryna help on the issue he is having :S

[rocky tree]

Yeah, I'd fix.
My error was very easy to fix xD

Thanks

[tall dragon]

ok. but again, you shoulnt use the name of an item to make it unique or a "custom item"

should be using pdc tags

[rocky tree]

Okk, thanks

[regal scaffold]

Alex when's the intelliJ gui plugin coming

[tender shard]

when intellij fixes their docs that explain how to write intellij plugins

i once tried, the docs were of a totally outdated version

so obviously everything was wrong and I didnt understand anything

@regal scaffold maybe I found a workaround to their shitty docs

[regal scaffold]

I'm blind

[tender shard]

RIP, that's outdated too

[regal scaffold]

2. chatgtp does know the way

[tender shard]

worldguard 6?!?!

isn't that like 10 years old?

[regal scaffold]

XD

[tall dragon]

well yea its learned from the shitty docs no? haha

[regal scaffold]

Yeah

How does it not work tho alex

Like wut

[tender shard]

just update to a still supported version of worldguard that's available in their repo

[tender shard]

wdym?

[regal scaffold]

IntellIj is massive and actively developed

Plguins are made daily

[tender shard]

no clue how people do it

I at least am not smart enough to understand it

[regal scaffold]

What's broke about their docs?

[tender shard]

using the current docs, that is

well, the first thing is how to even add a new wizard type. Couldnt find that in their docs

[regal scaffold]

Did you follow their getting started?

https://plugins.jetbrains.com/docs/intellij/plugins-quick-start.html

[tender shard]

not right now, right now I only used the builtin "IDE plugin" project template

[regal scaffold]

I read somewhere that was deprecated

They

"removed" it a while ago

[tender shard]

however I dont see ANY tutorial in this "quick start guide"

[regal scaffold]

https://plugins.jetbrains.com/docs/intellij/developing-plugins.html

[tender shard]

it tells about the general structure about a plugin etc, but not really any example on how to setup the workspace

[tender shard]

the class that chatgpt mentioned definitely doesnt exist anymore

i could ofc check the source code of the minecraft development plugin but I would rather see it explained in the official docs

also why the heck do people call it a "requirement" when it's optional

I am now trying to extend "ModuleType" as per the IJ docs but already stuck there.

[tall dragon]

also why mention something required that installs automatically 😄

[tender shard]

all they say is I should "derive" my custom module type from the existing class, giving no information about where I should obtain e.g. the builder from that I am supposed to return from that class. do I write that myself? can I use any existing one?

[tender shard]

yeah it's a pretty weird page

from what is explained in the docs, this should be enough for a IJ ModuleType. I highly doubt it's true

fun fact: intellij plugins must not contain the name "plugin"

which is a bit weird because this plugin's only purpose is to create spigot plugins, so obviously it wants to have "plugin" in its name

[tall dragon]

plug-in

[tender shard]

@regal scaffold if you know anything about IJ plugins, pls enlighten me. I have added exactly what the docs say, which is I created a custom ModuleType as seen above, and I added my moduletype to my plugin.xml. Still, when doing "new project", nothing's there

another funny thing is: their official example plugin ( linked here: https://github.com/bulenkov/RedlineSmalltalk/blob/master/src/st/redline/smalltalk/module/RsModuleBuilder.java) extends JavaModuleBuilder, but this class also does not exist anymore

[regal scaffold]

https://github.com/JetBrains/intellij-plugins here are up to date examples

I know a bit but I can't right now cause I'm trying to do something odd

I'm trying to fork CraftingStore to add an event that I need but I reached a point where if I add my method to their interface I need to create the methods for all 4 of their versions cause they have them separated....

So idk what to do

[tender shard]

I don't really find anything about "how to add a new project wizard" there

most plugins from that list don't even have a plugin.xml file o0

for real, how does one learn to do intellij plugins when every existing information about it is outdated

I just wanna know how other people managed to learn it without proper sources of documentation

[twin cliff]

Hi all, It's been years since I was doing any kind of plugin development.

Does anyone know a good template I can pull to start?

wtf is wrong with kotlin

the arrayOf method seems to be one of the funniest things ever, wtf is that

[vocal cloud]

Kotlin was a mess made to fix a mess

[hazy parrot]

Doest sponge inherit module wizard thingy

[tender shard]

obviously, otherwise the second screenshot wouldnt work

[hazy parrot]

I assume so, you can probably just cast that

Dk why it's erroring in ide, fully valid code lol

[tender shard]

nope

it's kotlin

e.g. this:

e: file:///Users/mfnalex/IdeaProjects/MinecraftDev/src/main/kotlin/creator/MinecraftModuleBuilder.kt:123:17 Type mismatch: inferred type is Array<BuildSystemWizardStep> but Array<ModuleWizardStep> was expected

it's just kotlin being stupid again

and that's what happens everyone when you think "consiseness" is more important than declaring the proper types lmao

[twin cliff]

Thank you, I've got something sorted and compiling now. Do you know the best place for where I can find the docs on different events? Specifically I'm looking for some kind of ContainerChange event to listen to all changes to a chest.

[hazy parrot]

working for me

well, if you do it like you do its not, you have to cast

lmao funny

[eternal oxide]

?jd-s

[undone axle]

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

[wet breach]

You can look at compiler source or plugin sources

[wet breach]

Not saying that is easy or even ideal

[tender shard]

see, isn't that a huge joke lmao

typical kotlin bullshit

[wet breach]

Love the infinite screens

[hazy parrot]

alright, i admit this is stupid

[tender shard]

weirdest thing I've seen today lol

I also still don't understand how to create a new intellij project wizard

I followed their tutorial 1:1 and it just shows this instead of my custom label.

[hazy parrot]

well, its same in java

[twin cliff]

InventoryMoveEvent seems good, does anyone know if this also handles things like,

• Player add Item
• Player remove Item
• Player break Chest (Moves to world)
• Player drags item out of chest (Moves to world)

[hazy parrot]

in kotlin you could just do, val array: Array<ModuleWizardThingy> = arrayOf(...)

to silent cast it

[tender shard]

works fine for me

[hazy parrot]

its generic type issue

[tender shard]

if that'd be the problem, then why does it get fixed by adding more objects to arrayOf

[hazy parrot]

because kotlin decides type under the hood if you didn't specify it explicitly

[tender shard]

funny lol

[hazy parrot]

if you have just 1 type, it will assume that supertype

[tender shard]

yeah explains it, typical kotlin bullshittery

also thanks for this totally useful error message intellij

yay, only took like 3 hours

another nice error message

Today I really hate IJ + gradle

another reason why IJ is a bad joke

anybode knows the awt equivalent of swing's JFrame?

oh I'm stupid, I meant a JPanel

[tender shard]

only been 29 hours so far lol

[chrome beacon]

Gradle speed

[analog thicket]

Hey, how would i go about making animated armorstands?

[eternal oxide]

Do you know Java?

[halcyon hemlock]

runnables

I'm not sure

[analog thicket]

Yeah mostly

[eternal oxide]

then you need to decide what type of animation you want

just the stand itself, or a set of stands

[analog thicket]

Probally more than one

But ill start off with one

[eternal oxide]

what kind of animation do you want? just move teh stand around? or move it's arms etc?

[analog thicket]

Move stand around, wanna make a crate animation when opening it.

But probally gonna move arms too

I know how to move the body parts, but not the whole armorstand

[eternal oxide]

ok, well moving is not hard, it's simply a case of deciding where you are moving to and progressively teleport teh stand in small increments over time

If you are using the normal scheduler and teleporting you can do 20 animations per second.

if you need a higher rate than that it's a little more complex as you need to use packets

[analog thicket]

All this works for 1.8.9?

[eternal oxide]

probably but you'll not get 1.8 specific support here

[small hawk]

Anyone have nice Color Util for Components, to easily transform HEX colors and more?

[analog thicket]

Hmm fair

finally

[final monolith]

Hey guys, trying to install a dependency on my pom.xml but gets an error.

mvn install:install-file –Dfile=Downloads\FILE.jar -DgroupId=group -DartifactId=artifact -Dversion=version -Dpackaging=jar

Error:
The parameters 'file' for goal org.apache.maven.plugins:maven-install-plugin:2.4:install-file are missing or invalid

[eternal oxide]

you didn't fill in any of the required parameters to install a jar to your local repo

file name, group, artifact, version

[final monolith]

i filled, i just changed the values to give an example

[spare prism]

?paste

[undone axle]

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

[eternal oxide]

can't help you with "examples"

[final monolith]

sorry

i tried with mvn install:install-file –Dfile=Downloads\oraxen-1.152.0.jar -DgroupId=com.oraxen -DartifactId=oraxen -Dversion=1.152.0 -Dpackaging=jar -X

[tender shard]

another person who has to install oraxen manually because their uploading to repo is still broken :X

[final monolith]

xD

[spare prism]

Code: https://paste.md-5.net/emiduvufeb.java
Exception: https://paste.md-5.net/owutuxizey.sql

Why would it give me this exception? I don't even use this method in my code and also it refers to a weird line:
} catch (FlagConflictException e) {

[tender shard]

the command looks correct

[tender shard]

your .jar doesnt match the source code. compile it again, do a full server restart, then check the exception again

[final monolith]

this

[tender shard]

or are you using an obfuscator or anything

[spare prism]

it's automatically compiled by IntelliJ every time I run it

[spare prism]

no

[final monolith]

delete the .jar before compiling it

and try again

[tender shard]

are you not using maven? o0

[spare prism]

I do

[tender shard]

then make IJ run mvn clean before package

[spare prism]

how? xd

[tender shard]

where it says "mvn package", change it to "mvn clean package"

[chrome beacon]

You're not using maven 💀

You're building an artifact rather than using maven to build the jar

Which probably means the new plugin jar isn't placed in the plugins folder

[spare prism]

it does

[chrome beacon]

Use maven to build your jar rather than that artifact

[final monolith]

ChatGPT solved my problem.

xD

[tender shard]

what was the issue

[final monolith]

it gives me a fixed command mvn install:install-file -Dfile=libraries/oraxen-1.152.0.jar -DgroupId=com.oraxen -DartifactId=oraxen -Dversion=1.152.0 -Dpackaging=jar -X

apparently its the \, needs to change to /

[tender shard]

oh I see the problem

you used the wrong hyphen

[final monolith]

xD

[tender shard]

see how it's not highlightig the "-" in front of -Dfile

[spare prism]

tried that now

nothing changed

I get the same stacktrace

[chrome beacon]

Don't use that run config to start the server

[spare prism]

I don't

[chrome beacon]

and delete the old plugin jar and make sure the server is stopped

when building with maven

[spare prism]

I did it

[tender shard]

yeah try again, see if the stacktrace changed

btw how do you copy the file to the server dir?

did you do that in your maven-jar-plugin declaration?

[spare prism]

tried that, nothing changed

[spare prism]

CTRL + C / V

[tender shard]

you let intelliJ run the spigot server but you manually copy the file? o0

that's a weird workflow

[spare prism]

no

when I tried to do that using Maven Build directly

I copied it manually

but normally I just let IntelliJ build the artifact directly there

and run the server

automatically

[tender shard]

?paste your pom pls

[undone axle]

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

[spare prism]

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

[tender shard]

looks good. if you manually stop the server, then copy over the file, then start the server again, and if this is actually your source code, then it should be impossible to receive this stacktrace

btw you can also make maven save the file in your plugins folder

[chrome beacon]

tbh I still think he's copy pasting the same old jar every time

[tender shard]

I also think that

[spare prism]

I can even try decompiling the plugin that is currently on the server

lol

[tender shard]

sure

or just add some debug message to your onenable

[chrome beacon]

also make sure you don't have two jars of your plugin in the plugins folder

[spare prism]

decompiler output: https://paste.md-5.net/zuhumucimi.http

[spare prism]

I don't

[spare prism]

it's exactly the same as the code that I've sent

[chrome beacon]

Send the new stacktrace

also add a debug message like mfnalex said

[spare prism]

it doesn't change

[chrome beacon]

Send it

anyway

[spare prism]

k

[tender shard]

and do this

I mean, the line number MUST change if you add a new line to the code

[spare prism]

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

[spare prism]

ok

[chrome beacon]

So the error is comming from ChunkBlockPlaceRestrict

[tender shard]

oh right lol

[spare prism]

oh

nvm

im retarted

XDDD

[tender shard]

it happens

[spare prism]

ty

guys

lmao

[tender shard]

definitely the most advanced CSV parser out there, EVER, lol

[icy beacon]

oh you solved the intellij plugins

last time I checked this channel you were throwing hands at it because of bad docs

[tender shard]

yeah the documentation was, as always, outdated or just plain wrong

[icy beacon]

yeah I had a similar experience recently

[tender shard]

I had to look into other plugins to see how it actually works

[icy beacon]

that really sucks

[tender shard]

although I still wonder, how anyone is supposed to know how it actually works

[icy beacon]

good code doesn't need documentation
© nobody

[tender shard]

🥲

[icy beacon]

I remember working with a scuffed API where params would sometimes be called var1, var2 and shit

some methods had random names like a8M3shit

and it was an actual api

not like nms or smth

[tender shard]

fancy

anyone knows a good XML library for me to read custom XML files and deserialize them into my custom objects?

I do NOT want any "automatic serialization/deserialization" such as XStream, I wanna have control about how it works myself

the main thing why XStream sucks because it doesn't support any lists or anything, or at least their docs don't say anything about it

[spare prism]

Is there a way to fix that? I'm trying to convert an Object (it's a list) to a List:

                    List<String> blocks = Arrays.stream((Object[]) value)
                            .map(element -> (String) element)
                            .collect(Collectors.toList());

java.lang.ClassCastException: class java.util.HashSet cannot be cast to class [Ljava.lang.Object; (java.util.HashSet and [Ljava.lang.Object; are in module java.base of loader 'bootstrap')

Before that I have this check:

value.getClass().isArray() || value instanceof Collection

[tender shard]

if it's a list, why do you cast it to an array?

[spare prism]

cause I can't use streams

otherwise

[tender shard]

you cannot cast a List to an array

[spare prism]

how do I use streams if I have an Object?

[tender shard]

please explain again which type "value" actually has

[spare prism]

Object

[tender shard]

no, what it actually is

not what it's declared to be

[tender shard]

you don't

[spare prism]

region.getFlags().get(flag): [dirt, grass_block]

[tender shard]

do .getClass() on it and show the result

(print it out or sth)

[spare prism]

ok

[spare prism]

class: class java.util.HashSet

[tender shard]

just cast your object to HashSet, then you can call stream on it

[spare prism]

like that?

                    List<String> blocks = ((HashSet<?>) value).stream()
                            .map(element -> (String) element)
                            .collect(Collectors.toList());

[tender shard]

yeah, although you could also just directly cast it to HashSet<String> instead of casting each element

List<String> blockTypes = ((HashSet<String> value).stream().collect(...)

[spare prism]

IntelliJ tells me that it's not recommended

[tender shard]

doing .map(...), then casting every element is doing the same thing, just more complicated

why do you need a List anyway? Can't you just use it as Set<String>?

[spare prism]

I can

ty

It works

Hello I have a problem:

Object worldname = main.getConfig().get("warps."+message+".world");
World world = main.getServer().getWorld((String) worldname);

config.yml :

warps:
  box:
    ==: org.bukkit.Location
    world: world
    x: 9.703408588152502
    y: 65.0
    z: 10.69579578168919
    pitch: 3.3000607
    yaw: -44.550293

[tender shard]

and what's the issue?

also why are you saving the worldname as "Object"?

[hazy parrot]

also not sure u are using correct path

[tender shard]

your config does not contain any value called "warps.<message>.world"

[feral bear]

what

[hazy parrot]

if you serialized that as location, get it as location

[feral bear]

yes

[tender shard]

I said that your config doesn't contain any value at the given path

hence it returns null

[feral bear]

@Override
    public boolean onCommand(CommandSender sender, Command cmd, String msg, String[] args) {
        
        if (sender instanceof Player) {
            
            Player player = (Player)sender;
            if (args.length == 0) {
                player.sendMessage("§6[§eYttrium§6]§4Oups...La commande est §6/warp §e{nom}");
            }
            if (args.length > 1) {
                player.sendMessage("§6[§eYttrium§6]§4Oups...Le nom du warp ne peut contenir que 1 éléments.");
            }
            if (args.length == 1) {
                
                StringBuilder message = new StringBuilder();
                for(String part : args) {
                    message.append(part);
                }
                Object worldname = main.getConfig().get("warps."+message+".world");
                World world = main.getServer().getWorld((String) worldname);
                player.sendMessage(main.getConfig().getInt("warps."+message+".y")+"");
                Location location = new Location(world, main.getConfig().getDouble("warps."+message+".x"), main.getConfig().getDouble("warps."+message+".y"), main.getConfig().getDouble("warps."+message+".z"), main.getConfig().getInt("warps."+message+".pitch"), main.getConfig().getInt("warps."+message+".yaw"));
                player.sendMessage("§6[§eYttrium§6]§e Téléportation en cours...");
                player.teleport(location);
                player.playSound(player.getLocation(), Sound.ENTITY_EXPERIENCE_ORB_PICKUP, 1.0f, 1.0f);
                        
                
            }
            
        }
        
        return false;
    }

[tender shard]

then you throw null into "Server#getWorld(String)" so it throws an NPE

[hazy parrot]

this code is so wrong

[tender shard]

also why do you have two arguments that are both called msg/message ?

[hazy parrot]

also string builder for array lenght 1

[tender shard]

yeah that also makes little sense

[feral bear]

I am a beginner

[hazy parrot]

plus you already saved location in config

[tender shard]

the "msg" variable should be called "label"

[hazy parrot]

you can just use get() and cast it to location

[tender shard]

what's the purpose of using a StringBuilder if you already checked that your "args" has a length of 1?

or use getLocation()

[feral bear]

okay

[tender shard]

but that'll error out if the world is not loaded

[feral bear]

I try

[hazy parrot]

ah didn't know that exist

[tender shard]

final Location myLocationFromConfig = myPlugin.getConfig().getLocation("path.under.which.i.saved.the.location");

[feral bear]

Tanks It work

[tender shard]

np

what the heck is wrong with baeldung's method naming scheme, wtf

[mortal hare]

that's a test method

[tender shard]

obviously

[opal juniper]

new Constructor

[tender shard]

is there any rule that I missed which states that test method names must both be misleading, way too long and also violate existing naming schemes?

[mortal hare]

who cares

[echo granite]

Ok I noticed the method name lol

[final monolith]

lmao

[mortal hare]

they dont want to make a comment that's a sentence long

i guess

[tender shard]

idk I just feel that this method name hurts

[mortal hare]

you

are right

it really does

[tender shard]

I would have called it "testYamlParsingWithNestedObjects()" or sth lol

or "üüaaagh()"

[final monolith]

You're wrong. just remove the _ and the method name gots perfection 😎

[tender shard]

I don't think so, for example the weird "when" prefix, or the fact they mention it's about a "JavaObject" when basically everything in java is about java objects

what else would it be if not a java object

I mean, what else would it be? a C(++) template/struct?

makes little to no sense to mention this specifically

is it normal that gradle gives no useful output even when running gradle test --full-stacktrace? o0

anyway, found the proper stacktrace in the html file. anybody know how to fix this?
Stacktrace: https://paste.md-5.net/yepahisudi.cs
build.gradle.kts: https://paste.md-5.net/adiyevanez.cs
Test class: https://paste.md-5.net/oteyimirav.java

I followed this tutorial on how to add tests in gradle: https://docs.gradle.org/current/userguide/java_testing.html

are their docs outdated on that too o0

is there actually ANYTHING correct in gradle's docs?

note: it also fails to run when my @Test method is completely empty

I cant figure out to get the item in the main hand. How do i do this?

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.

you already know how to get the item in main hand, it's Player#getInventory()#getItemInMainHand()
