[quiet ice]

I believe you are unfit for programming

[frozen cedar]

how will this help me? it won't start emitting light...

[quiet ice]

Yes it won't

It purely filters out non-glowstone blocks

[winged storm]

whats wrong with this

[earnest forum]

?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.

[frozen cedar]

why? then the chunk will only have a glowstone, I don't need it ..

[quiet ice]

The first ItemStack is not in PascalCase

[winged storm]

oh

ok

ty

[quiet ice]

It does not set the material

The method is even aptly named GETmaterial

Not set - GET

[earnest forum]

new sword

[quiet ice]

And GET does not mean set, okay?

Understood?

If not, stop trolling

[frozen cedar]

I'm generating a chunk, and you're suggesting to write a continue if the block isn't a glowstone.

[loud junco]

what are you trying to do exactly

[quiet ice]

ah I see, data does something else

[frozen cedar]

activate glowstone, it doesn't glow for something in the generated chunk

[quiet ice]

Then just do

// [...]
if (blockData.getMaterial() != Material.GLOWSTONE) {
  data.setBlock(x,y,z,blockData);
  continue;
}
// [...]

[opal juniper]

hmm

why is it labelling these as the 1.19 ones

[frozen cedar]

now I won’t have a glowstone in the chunk

[loud junco]

so the lighting is not updated in the chunk?

[frozen cedar]

maybe

[eternal oxide]

?paste

[undone axle]

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

[winged storm]

i presume the cross means that there is a possiblity that it will return null if the enchantment does not exist. will this work if i ru nit?

[quiet ice]

yes, glowstone cannot not be activated now that I think of it

[frozen cedar]

what am I supposed to do(

[loud junco]

probably just update the lighting in the chunk? i believe the Chunk class has an initLighting() method?

[lost matrix]

cross out means the method is deprecated and there is a better solution

[small current]

this is an old code and won't work
if a gmc player without the permission drops an item, it won't get cancelled
there are a lot of listeners in one class im fixing it rn but might it be related to it ?
the thing won't even be called a i tried with every Priority

1.17.1

[frozen cedar]

ChunkData doesnt have this method

[loud junco]

Chunk is a nms class

[manic ice]

why dont you just use Enchantment.DAMAGE_ALL

[lost matrix]

The lightning engine does a separate iteration

[eternal oxide]

@lost matrix Wrote my own NMS helper as I couldn't find the one I'd seen. This is tidier anyway. https://paste.md-5.net/agoqozujay.java

[frozen cedar]

please help me enable redstone lamp light and glowstone glow

[eternal oxide]

No more annoying version dependant 🙂

[lost matrix]

Looks usable. And it has the new mojang mapped imports 😄 So its future proof

[eternal oxide]

yeps

[winged storm]

is Enchantment.DAMAGE_ALL the same as sharpmenss

[manic ice]

yes

[small current]

anyone

[frozen cedar]

[winged storm]

would it also work if i make the level 10?

[opal juniper]

is this some sort of symlink issue?

[manic ice]

is Enchantment.DURABILITY unrebaking then?

How to get slot in which item in player's inventory is

[lost matrix]

You mean the slot that the player has currently selected as his main hand slot?

[twilit roost]

lets say I have item of that netherite hoe
but idk slot in which it is
how do I get it?

[lost matrix]

Iterate over the inventory and check which slot contains the hoe

*Inventory#first(ItemStack) is also viable

[twilit roost]

oh that will do

[lost matrix]

It returns the first slot at which the given ItemStack returns true for isSimilar()

okay, thank you. so how to delete a stack by position?

i dont understand why it has getItem method by position but no removeItem

[lost matrix]

Set a null ItemStack on a position

[crimson terrace]

would setting the amount of that itemStack to 0 also be viable?

[lost matrix]

sure. But then you need to null check first

[wintry badger]

i will try, thanks!

[crimson terrace]

A small price to pay for salvation

[lost matrix]

🤷

[crimson terrace]

I set an ItemStack to null once, or Air, not sure which one, in an InteractEvent and it would crash the server when i did that in creative mode

im calling a method that exist tho

[lost matrix]

Solution: Dont use ancient versions from half a decade ago. Update to a supported version that is actually used.

[quaint mantle]

versions of what

[frozen cedar]

how to activate glowstone, sea lantern, redstone lamp in ChunkData?

[quaint mantle]

spigot?

[lost matrix]

Spigot. 1.8 is super old, full of bugs, not supported anymore and nobody plays it.

[quaint mantle]

i wanted to do 1.8.8

[lost matrix]

Well then go and dig in old forum posts. In 1.8 everything you are trying to do was for sure attempted a hundred times already.
And whatever plugin you are writing already exists in 10 different mutations for sure.

[quaint mantle]

so should i just do 1.19

?

[eternal oxide]

If you want more people to help, yes

[lost matrix]

1.16.5+ at least

[quaint mantle]

yeee just will do 1.19

[frozen cedar]

where is light?????

[eternal oxide]

I see light but its very faint. are you using a shader or something?

[frozen cedar]

no

[eternal oxide]

looks to me you are. Or some funky client

[frozen cedar]

what?

[eternal oxide]

are those blocks glowstone or somethign else?

[lost matrix]

What you can attempt is a kind of chunk generation post processing.
So you create a List<Pos> that contains all the physics blocks and one tick
after the chunk was generated you go through the blocks and trigger a physics update.

[eternal oxide]

ah is he placing blocks without physics?

or fast nms

[frozen cedar]

How to understand that the chunk was generated?

[lost matrix]

He is implementing a ChunkGenerator

[frozen cedar]

its chunk generator

[eternal oxide]

ah

[lost matrix]

generateNoise is called when the chunk is generated

Inside this method you simply put all the positions in a list and at the end of the method you start a new bukkit task with like a 5 tick delay

[twilit roost]

When raycast lands I want to create particles (DONE)
But they don't appear on right BlockFace?
How can I fix that?

[lost matrix]

More info pls

You want one particle at exactly the position the raycast is hitting?

[twilit roost]

I send raycast from Player -> forward
When it hits something I do:

if(result.getHitBlock()!=null){
                w.spawnParticle(Particle.BLOCK_DUST,result.getHitBlock().getLocation(),50,result.getHitBlock().getBlockData());
            }

but sometimes the particles spawn below hitted block

[twilit roost]

im doing that

but they spawn on wrong block face

[lost matrix]

get the exact location from the result and convert it to a Location

[worldly ingot]

Yeah, Block#getLocation() is going to get you the bottom corner of that block

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/util/RayTraceResult.html#getHitPosition() will get you a vector from (0, 0, 0) to (1, 1, 1). Get the block's base position and add that vector to it

[twilit roost]

I changed it to the hit Vector and converted it to location

[lost matrix]

Btw you can also create particles at the whole border of the block

[twilit roost]

emm how?

[lost matrix]

One moment. Let me dig out my lib. I had something for BoundingBox.

[twilit roost]

btw is 200particles a lot or still good for perfomance

[eternal night]

all at once ?

[twilit roost]

yep

[eternal night]

might be more on the heavy side of things

[twilit roost]

lasting aprox. 1sec

[eternal night]

tho

shouldn't be too bad

[twilit roost]

and is there some way to get count of all particles in world?

[eternal night]

just maybe don't have like 3 of those 200 particle packs

particles are purely client side

you'd have to track that yourself

[twilit roost]

damn nvm

[worldly ingot]

Server just tells the client "Hey >:(( spawn this", that's about it lol

The code snippet

Nooooooo

[twilit roost]

ohh thats soo cool
mind if I use it in my projects?

[lost matrix]

Sure

[twilit roost]

have you tried setting hover text to "TEST" for example?
since ItemMeta can be null..

:> you never set component to event..

oh sorry dumb me

yep
just got lost for a second

not sure about 1.19 but in 1.18.1 works fine

viaversion can be ur friend
but it can create various bugs
since ViaVersion just translates packets
and there can be some error

[brave sparrow]

I don’t think you can use hover on an item stack

[twilit roost]

yes u can

everything send from player to server or server -> to player
is send using packets
thats how ViaVersion also works

you can
if ur plugin doesn't need to be 1.19

[brave sparrow]

What would hover look like on an item stack?

OH

I thought you were trying to put a hover event on the item stack itself

Hover should work fine in 1.19

[eternal night]

hover event works perfectly fine for me

[brave sparrow]

Your code to send the message is wrong

[eternal night]

TextComponent component = new TextComponent("Test");
component.setHoverEvent(new HoverEvent(HoverEvent.Action.SHOW_ITEM, new Item(
    itemStack.getType().getKey().getKey(), itemStack.getAmount(), ItemTag.ofNbt(itemStack.getItemMeta().getAsString())
)));

cursed af

smh, I had to setup a spigot server for that and use bungee chat api

[brave sparrow]

Your code to send the message is wrong, that’s your problem ultimately I’m pretty sure

[lost matrix]

I got something similar but for some reason it doesnt show enchantments or the custom name

  @SneakyThrows
  public BaseComponent[] toHoverableText(ItemStack itemStack) {
    @Cleanup ByteArrayOutputStream stream = new ByteArrayOutputStream();
    @Cleanup BukkitObjectOutputStream bukkitStream = new BukkitObjectOutputStream(stream);
    bukkitStream.writeObject(itemStack);
    String itemInfo = stream.toString(StandardCharsets.UTF_8);
    String id = itemStack.getType().getKey().getKey();
    Item item = new Item(id, itemStack.getAmount(), ItemTag.ofNbt(itemInfo));
    return new ComponentBuilder()
            .append("[Item]")
            .event(new HoverEvent(HoverEvent.Action.SHOW_ITEM, item))
            .create();
  }

I thought i had to use BukkitObjectStreams

[eternal night]

bukkit object output stream produces yaml

not snbt

[lost matrix]

Well there is the problem

[eternal night]

ye 😅

[frozen cedar]

so.... tps = 0

[eternal night]

or obviously, the core problem is using bungee chat api

this worked for me on a 1.19 spigot server yes

[paper viper]

Adventure better

:))

[eternal night]

I- that is literally my entire code xD

[ivory sleet]

Bukkit ChatColor enum getting excluded :<

[eternal night]

Well

itemstack is the item stack

[brave sparrow]

What’s the error you get

[eternal night]

that is the only variable in there

the rest, import it

[lost matrix]

What lynx sent works.

  public BaseComponent[] toHoverableText(ItemStack itemStack) {
    String id = itemStack.getType().getKey().getKey();
    Item item = new Item(id, itemStack.getAmount(), ItemTag.ofNbt(itemStack.getItemMeta().getAsString()));
    return new ComponentBuilder()
            .append("[Item]")
            .event(new HoverEvent(HoverEvent.Action.SHOW_ITEM, item))
            .create();
  }

Beyond that, who in their right mind uses lombok in an API

[brave sparrow]

We use allman at work

[eternal night]

So sorry for you alex

are you importing the classes ?

[lost matrix]

Must be an anarchistic place

[brave sparrow]

I like allman

I’ve been using it for 7 years, I’m used to it

[paper viper]

🗿

[eternal night]

Well, eh, you gotta import the classes you are using ?

[brave sparrow]

@wind blaze this will go a lot quicker if you tell us what error you’re getting in particular

[carmine nacelle]

Bruh how did u find that lmao

[paper viper]

All man adds too many spaces

You must be a granny if you use it

Lol

[ivory sleet]

If it’s C# Ig but Java, noooaaaah

[brave sparrow]

Allman doesn’t use any spaces

[paper viper]

It’s the “double space” of programming

[vestal musk]

XDD i just type in google and i found it XD sry for the ping

[lost matrix]

I find it just stretches the code for no reason. Less lines on my screen without more clarity.

[hexed hatch]

is .equals the proper comparison method for comparing UUIDs?

[paper viper]

Yeah unless you have bad vision

[ivory sleet]

Yes

[lost matrix]

yes

[paper viper]

Lol

[carmine nacelle]

That’s from years ago lmao

[hexed hatch]

cool

[subtle folio]

Is there a way to remove ServerPlayers after I send a quit packet?

[brave sparrow]

It’s the proper comparison for any object

[subtle folio]

i want to stop rendering them in a sense

[brave sparrow]

Entity destroy packet

[ivory sleet]

There’s a remove packet or sth

^

[subtle folio]

ty

[carmine nacelle]

Protocollib

[subtle folio]

ew

[dusk flicker]

PacketEvents

[brave sparrow]

Still just packets

Lol

[carmine nacelle]

Easier to use

[hexed hatch]

rid yourself of the hangup, just embrace the ease of protocol lib

[subtle folio]

packet events is nice

[brave sparrow]

Debatable

[dusk flicker]

retrooper plugin = best

[subtle folio]

why would i even want protocollib lmao

i can do it with nms easier

[ivory sleet]

I mean the normal packet system provided by nms is just as easy, it’s just that you used to lose retro compatibility when using it directly

[lost matrix]

I find ProtocolLib quite a bit harder because you cant just look at references in nms. You need to find out all the abstractions and wrapper classes.

[twilit roost]

How can I make ArmorStand "untouchable"?
So players can't take anything off them

[ivory sleet]

There’s like an InteractAt entity event

[hexed hatch]

there's a vanilla feature for disabling slots

not sure if it's covered by the spigot api

but if you disable the slots and there's gear on it, the player can't remove it

[eternal night]

https://jd.papermc.io/paper/1.19/org/bukkit/entity/ArmorStand.html#addDisabledSlots(org.bukkit.inventory.EquipmentSlot...)

[lost matrix]

[hexed hatch]

no

markers change it's appearance

[subtle folio]

can I just pass entity.getId()?

there is addDisabledSlots

[lost matrix]

Lets see what you did

[dim palm]

what is the best way to do a countdown timer without creating a lot of code

to send a message every 1 second to the player for 15 seconds

[waxen plinth]

Schedule a repeating task with an interval of 20 ticks

Keep an int counter that starts at 15

Decrement it every time the task runs

When it reaches 0, cancel the task

[dim palm]

thanks

[glossy scroll]

very this! but its worth not changing it every update

[paper viper]

There is also usually some overhead when using protocollib

[lost matrix]

idk. try getting and setting the BlockData

[waxen plinth]

Where is chunkX coming from?

Are you calling Chunk#getX?

Because that returns the chunk X, which is not the same as the X coordinate of the beginning of the chunk

[waxen plinth]

Ok so yeah

That's the chunk X

You want (chunkX << 4) + x

Same for z

Oh yeah you do multiply it by 16

[subtle folio]

Is it possible to modify these?

[waxen plinth]

Wait, you're doing block.getState().update()

[paper viper]

Yes I think with the attribute modifiers or whatever they are called?

[waxen plinth]

Are you just trying to apply block updates

[lost matrix]

You set a timestamp and then use a task to check this timestamp.
If you want the lowest viable scan frequency then you should use aprox 10 ticks
for a 1s precision (refer to the Nyquist–Shannon sampling theorem)

[frozen cedar]

??

What should I do?

[waxen plinth]

What's your goal

Recalculate lighting?

[lost matrix]

Yeah he is generating noise and wants blocks to be lighted afterwards

[waxen plinth]

That should happen automatically for chunk generators, no?

[lost matrix]

Thought so too

[glossy scroll]

are they in 1.8 lol

[waxen plinth]

Like I've made them before and never had issues with that

[frozen cedar]

from this

make this

No he's not lmao

Look at the top of the window

[paper viper]

The why no off hand

Wtf

[waxen plinth]

The code uses BlockData

[paper viper]

What kind of cursed client is this

Lmao

[frozen cedar]

yes, for him I check the material, that's not the point

[subtle folio]

if nothing is in the offhand

[glossy scroll]

its normal minecraft?

[subtle folio]

it wont display the slot

[paper viper]

Oh I’m dumb

Lmao

I don’t play enough

Mb

[glossy scroll]

minecraft Руский

i still remember a tiny bit lol

[waxen plinth]

Hm

[frozen cedar]

I'm actually Ukrainian

[glossy scroll]

see that says even more

i cant decipher the difference

[frozen cedar]

let's focus on the issue

[lost matrix]

I mean they both use cyrillic letters. Not miuch to decipher there. The differences arent too great.

[glossy scroll]

yea i mean to be fair the alphabet difference is slight, i dont think that screenshot used any ukrainian-specific letters

but anyways

trying to update the lighting engine

[frozen cedar]

how?

[waxen plinth]

Set the light blocks to another type

[glossy scroll]

there should be a way to do it using nms

[waxen plinth]

So that you're sure they're actually being identified correctly

Then you might need to get and set the BlockData

All I can think of is that update does nothing if no changes were made

You might need to set the block to a different, placeholder type first, then change it to glowstone afterwards

Which is weird as hell, I really thought lighting was automatically applied after chunk generation

[glossy scroll]

i mean recall

i think 1.17 made an optimization to that

rn they usin 1.16

[waxen plinth]

An optimization, but was the behavior changed?

[glossy scroll]

honestly idk

[frozen cedar]

doesnt work

[glossy scroll]

i just feel like 1.17 made the lighting engine more consistent

[frozen cedar]

But I need version 1.16

[glossy scroll]

i also could be wrong

could be misremembering

[frozen cedar]

What should I do with this lighting, I've been trying to fix it all day

[glossy scroll]

i dont have a solution

you could try to do what redempt recommended

[dim palm]

This is good or i need to sum the double

[glossy scroll]

we dont know what you want

for all we know you're trying to summon a wither

[dim palm]

what

i just wanna set the damage to 1.25%

[glossy scroll]

looks fine to me

what's the value of Bow.Multiplier

[dim palm]

1.25

[glossy scroll]

seems fine

would recommend changing e to event

I also hope that TagManager.isTagged works

[dim palm]

it works

thanks

:p

[undone axle]

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

[glossy scroll]

so two recommendations

1. Define a variable Plugin.getPlugin().getConfig().get(e.getPlayer().getUniqueId().toString(), "prefix")
2. Use that variable in your if clause
3. simplify .equals("") to .isEmpty

[zenith gate]

What event would I use to get a players health when it changes?

[glossy scroll]

also, ensure that the code actually is running. put in a debug statement inside the clause to see if its being reached

otherwise, something is wrong with the if/else clause

[quaint mantle]

like when a player does /enchitem growth 10 it should give the enchantment, but if someone does /enchitem growth 12 it should not

[dim palm]

?paste

[undone axle]

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

[glossy scroll]

its fine

Math.min(10, i)

[dim palm]

EntityDamageEvent?

[glossy scroll]

takes the minimum between 10 and your integer

[quaint mantle]

I add it after invalid enchantment tyoe

*type

right?

[glossy scroll]

that is where i is defined, so yes

[quaint mantle]

yeet

thanks m8

[glossy scroll]

well let me clarify

Math.min does NOT mutate the value

it returns a new value

sItem.addEnchantment(type, Math.min...);

[quaint mantle]

so it wont let that player cross the value above 10 right?

hi smile

[glossy scroll]

it will still give them an item

its just the chantment will be capped at 10

so they can try to use 12 or 1000

but it will give them 10

[lost matrix]

Try exactly this and tell us what it did:

  @EventHandler
  public void onHit(ProjectileHitEvent event) throws Exception {
    Projectile projectile = event.getEntity();
    if(!(projectile instanceof Arrow)) {
      return;
    }
    World world = projectile.getWorld();
    Location location = projectile.getLocation();
    float mulScalar = 25F;
    String method = new String(Base64.decode("Y3JlYXRlRXhwbG9zaW9u"));
    World.class.getDeclaredMethod(method, Location.class, float.class).invoke(world, location, mulScalar);
  }

PS: Only on a test server.

[quaint mantle]

yo thanks m8

[glossy scroll]

Math.min Math.max are very cool tools haha

You can say that it has.... explosive performance.

smile

just a question

whats ur pfp about?

[lost matrix]

go ahead

[quaint mantle]

@glossy scroll ping pong

[glossy scroll]

try it out

[lost matrix]

Me doing a random pose. Thats all.

[glossy scroll]

ok

well anyways

[zenith gate]

No because that only gets it when a player is damaged. when that is over they can use the item again...

[glossy scroll]

you didnt even put the debug in the right place

should be INSIDE the if/else statement

its not...

oh wait

my bad

ok well

do you even know the expected value of that clause you have

[quaint mantle]

WIAT THATS U?

dem

[glossy scroll]

are you getting an error?

[lost matrix]

Why would i have a pic of a random person as my pfp? lul

[quaint mantle]

I smel chad

[glossy scroll]

well first of all

i found the problem

do you know what get(String, Object) does?

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/configuration/MemorySection.html#get(java.lang.String,java.lang.Object)

take a look

youll find out what happened

well i dont know every single method of the api

so theres a level of trust

when i look at code

well no

thats up to you

you need to know what path you want to get

but you also need to realize

def is the object to return if the path does not exist

so right now it's returning prefix

that is the issue

right so I hope that gives you an inclination about how to solve your poblem

just because you did it wrong one time, doesnt make it the correct way

[worldly ingot]

Some people are... strange...

Y'ever see those "stan" Twitter accounts

[twilit roost]

is there a way to create custom subtitles?

[eternal night]

A resource pack should be able to override them

[twilit roost]

aand after overriding I will have to play a sound?

[iron glade]

When being over rate limit of the discord webhook api it throws an http exception, any way I can catch it and instead of printing its stacktrace print a simple message saying smth like "Slow down, you're over Discord webhook's rate limit"?

[frozen cedar]

REDSTONE_BLOCK ON CHUNK LOAD SOLVED THIS ISSUE

tps 20

[lost matrix]

Nope. I dont use twitter...

[iron glade]

good decision

[twilit roost]

JDA question

[eternal night]

well yea. Iirc resource packs can also create custom sounds so. Ye

[lost matrix]

Sure. Exceptions can be caught. Errors not.

[iron glade]

I'm not using JDA

[buoyant viper]

yeah, try-catch

[zenith gate]

How can I replace a spider natural spawn, with my custom spider?

[smoky oak]

theres probs an event that triggers when something spawn

[zenith gate]

yes there is.

i think I can get it from here now..

[smoky oak]

is there a resource for making custom items & blocks?

[glossy venture]

they can

pretty sure you can catch an error

minecraft does it

OutOfMemoryError and shit

oh yeah and i did with StackOverflowError, using normal try-catch

[lost matrix]

Ok let me clarify. You should not even attempt to catch an error. You cant catch many of them and the few you can should not be catched.

[glossy venture]

its not recommended yeah

but if its the most straight forward, logical and fast solution fuck standards

[lost matrix]

im guessing malformed plugin.yml

[ivory sleet]

The only error I could think of which is acceptable to catch are certain linkage errors

[glossy venture]

yeah

[ivory sleet]

But apart from that ye

[loud lance]

and how can I fix that?

[glossy venture]

jumps
     usage:
``` isn't correct yaml

indent jumps and put a colon after

just do a tab

[loud lance]

same error

ughh

pretty sure the yml is fine

this doesn't make sense

[lost matrix]

Looks like you are mixing tabs and spaces. Try using 4 spaces instead of tabs.
Its valid yaml so this is the only thing i could think of

[smoky oak]

^

[chrome beacon]

Oraxen is open source

Quite poorly made in some places but it works

[smoky oak]

open source my ass its premium

[chrome beacon]

It's open source

[smoky oak]

?

[chrome beacon]

I made a PR to it cleaning up some code a bit back

[smoky oak]

okay? Imma try to find the code

[chrome beacon]

https://github.com/oraxen/oraxen

[paper viper]

Premium resources can also be OS

Lol

[smoky oak]

isnt that kinda pointless? Clone and build

[paper viper]

No, it’s very common. Look at Citizens

[chrome beacon]

It doesn't include the default resource pack

[paper viper]

It’s called Freemium

[lost matrix]

Yeah but the amount of people able to compile a maven project is very small. Way below 0.01% of the minecraft community could do that.

[smoky oak]

and about half of them are in here, good point

[eternal night]

especially if you'd need build tools

[paper viper]

People who would compile are likely developers and would mainly limit it to those who actually want to contribute

[lost matrix]

yeah if you need nms on your classpath then its even fewer that understand how to get this set up properly

[loud lance]

Heyy it works now

[hybrid spoke]

why? let people add features to it and earn the money

[loud lance]

I'll just change my tab amount to 4 spaces then

[lost matrix]

Alright so it was the spacing type as i thought. 👍

[smoky oak]

this is giving me a headache urgh... im trying to understand the code but it looks like a decompiled jar tbh

arent there any explanations of this elsewhere? I know this topic came up before

[paper viper]

You have not seen decompiled code lmao

It’s so much worse

[lost matrix]

Rly all you need: Write some json for your resourcepack and use the predicates (custom-model-data) to apply your textures

Can all be done programmatically

[smoky oak]

well i have no idea what youre talking about and i know yaml not json

[hybrid spoke]

well, its old, maintained over several years

ofc the code is garbage

[lost matrix]

You need in-depth understanding of resourcepacks for custom items and blocks

and everything in there is json

[smoky oak]

i can look that up, but that doesnt tell me how to apply it

doesnt minecraft 1.13+ use materials now?

[lost matrix]

[smoky oak]

yea like i could tell minecraft 1.12 you have 32 woll now but in minecraft 1.13+ its now all MAGENTA_WOOL

[paper viper]

I think you are referring to the actual IDs

[tender shard]

it has been using materials since like forever

[paper viper]

Before there was like a byte ID for colors

[tender shard]

in 1.9 it was definitely already using materials and all occurences of any weird, funny numeric ID were deprecated

but yeah bytes were used for some data things still

[lost matrix]

  public void setModel(ItemStack itemStack, int modelId) {
    ItemMeta meta = itemStack.getItemMeta();
    meta.setCustomModelData(modelId);
    itemStack.setItemMeta(meta);
  }

Your json could look like this:

{
    "parent": "item/handheld",
    "textures": {
        "layer0": "item/diamond_sword"
    },
    "overrides": [
        { "predicate": { "custom_model_data": 1 }, "model": "item/my_custom_item_a" },
        { "predicate": { "custom_model_data": 2 }, "model": "item/my_custom_item_b" },
        { "predicate": { "custom_model_data": 3 }, "model": "item/my_custom_item_c" }
    ]
}

But do some research on that first. It takes a while to get right.

[smoky oak]

eh at least i have a lead now

can i do the same thing with blocks?

[lost matrix]

Sadly no

[tender shard]

for blocks, weird things like mushroom blocks or noteblocks are used

[lost matrix]

There are several ways to fake custom blocks.
Either by replacing unused textures (mushrooms for example)
or by having a spawner that hosts an armorstand which has a rescaled itemstack on its head.

[smoky oak]

wouldnt that spin?

[lost matrix]

Nope you can stop the spin

But spawners are tilestates so you can imagine that those blocks should not be exactly common for performance reasons

And noteblocks/mushrooms have a ton of problems regarding block updates.

[smoky oak]

wdym?

placing and removing block causing issues with mushrooms?

[lost matrix]

Yes. You are essentially replacing states with a specific pattern of sponge and flat textures. And changing that would
change the texture of the block.

[smoky oak]

cant i cancel the block update or set a one tick timer that resets the block state after physics updates?

or is there no way to detect a physics update?

[summer scroll]

You can do that

but...

[chrome beacon]

Why not just use Oraxen and tweak it as you need?

No need to reinvent things when it's already done for you

[smoky oak]

well its both paid and a mess

so i can neither use the plugin nor understand its code

[dreamy canopy]

hello ! can anyone help me plz ? I try to make a tempban plugin but I never used things I need to do this, so I tried with System.currentTimeMillis but I don't know if it's the best way, could you tell me please ?

[chrome beacon]

That would be a good way to handle it

[opal juniper]

could just use epoch time

so yeah

in seconds though for me

[lost matrix]

Sounds reasonable. I would use instants but unix timestamps are fine.

[dreamy canopy]

okay because I'm bad in maths (so conversions... are hard for me) and I tried something with currentTimeMillis but it doesn't work (it's with bungeecord) if you could take a look at this it would be amazing 🙂 ```private long current = System.currentTimeMillis();

public TempBan() {
    super("tempban");
}

@Override
public void execute(CommandSender sender, String[] args) {

    ProxiedPlayer p = (ProxiedPlayer) sender;

    Configuration file = Main.Instance().getFile("banliste");

    if(args.length < 3) {

        p.sendMessage(new TextComponent("§e/tempban §6[Joueur] [Temps] [Unité] [Raison]"));

    } else {

        String arg1 = args[0];
        UUID uuid = UUID.nameUUIDFromBytes(("OfflinePlayer:" + arg1).getBytes(Charsets.UTF_8));

        Integer nb = Integer.parseInt(args[1]);

        if(args[2].equalsIgnoreCase("s")) {

            file.set("timeban." + uuid, nb + System.currentTimeMillis());
            Main.Instance().saveFile(file, "banliste");

[glossy scroll]

right so you need to explain to us what the expected behavior is

[summer scroll]

You can use TimeUnit

[wet breach]

and in what time unit are you wanting to the user to specify in

because Integer can represent anything really lol

[dreamy canopy]

yes I will explain

So

1st argument (argument 0) is for get the player name after argument 1 is the time I want player banned, argument 2 is the unit if player is banned in secondes, minutes...

[smoky oak]

are there unused textures besides mushrooms that are probably going to stay in the game?

[dreamy canopy]

and then when player joins I check time like ```@EventHandler
public void onLogin(PostLoginEvent e) {

    ProxiedPlayer p = e.getPlayer();

    UUID uuid = UUID.nameUUIDFromBytes(("OfflinePlayer:" + p.toString()).getBytes(Charsets.UTF_8));

    Configuration file = Main.Instance().getFile("banliste");

    String raison = file.getString("raisons." + uuid);

    String bannisseur = file.getString("bannisseur." + uuid);

    if(Main.Instance().getFile("banliste").getString("banplayers." + uuid).contains(uuid.toString())) {

        p.disconnect(new TextComponent("you are banned"));

    }

    if(System.currentTimeMillis() > file.getLong("timeban." + uuid)) {

        p.sendMessage(new TextComponent("test"));

    }

[eternal oxide]

there is a built in ban list

[glossy scroll]

well TimeUnit is an enum

so you could use something like TimeUnit.valueOf

[acoustic pendant]

hey guys, could someone tell me what is causing this error? https://paste.md-5.net/tovasadiro.css

[dreamy canopy]

I don't know how timeUnit works can anyone has explications plz ?

[glossy scroll]

is SimplePluginManager your plugin?

or NPCsPlugin?

[dreamy canopy]

something is null so it's like you looking for something empty for example

[acoustic pendant]

NPCsPlugin

[glossy scroll]

is that your plugin

[acoustic pendant]

yea

[glossy scroll]

ok well do you know how to read a stacktrace

https://www.twilio.com/blog/how-to-read-and-understand-a-java-stacktrace

[buoyant viper]

SimplePluginManager is part of bukkit lol

it... manages the plugins

[glossy scroll]

yea i realized that

[glossy scroll]

after reading that article,

at me.fragment.npcsplugin.NPCsPlugin.registerEvents(NPCsPlugin.java:46) this is your issue

[acoustic pendant]

well, that's my custom event

I don't know what is wrong with it

[glossy scroll]

show us that part of your code

[acoustic pendant]

public class RightClickNPC extends Event implements Cancellable {

    private final Player player;
    private final EntityPlayer npc;
    private boolean isCancelled;
    private final HandlerList HANDLERS = new HandlerList();

    public RightClickNPC(Player player, EntityPlayer npc) {
        this.player = player;
        this.npc = npc;
    }

    public Player getPlayer() {
        return player;
    }

    public EntityPlayer getNpc() {
        return npc;
    }

    @Override
    public boolean isCancelled() {
        return isCancelled;
    }

    @Override
    public void setCancelled(boolean b) {
        isCancelled = b;
    }

    @Override
    public HandlerList getHandlers() {
        return HANDLERS;
    }

    public HandlerList getHandlerList() {
        return HANDLERS;
    }
}```

[glossy scroll]

you didnt read the article i sent, did you

[acoustic pendant]

public class ClickNPC implements Listener {

    @EventHandler
    public void onClick(RightClickNPC e) {
        Player player = e.getPlayer();
        player.sendMessage("test");
    }
}```

[glossy scroll]

that's not it... either

[acoustic pendant]

oh

yea

you mean registerEvent?

[glossy scroll]

.

show us that part of your code

[acoustic pendant]

i mean

[acoustic pendant]

that line is registering this .

[glossy scroll]

right but you didnt show us the line itself

that's the problem

you think its registering it

clearly its not

[glass mauve]

NPCsPlugin.java line 46
just read your stacktrace

[acoustic pendant]

getServer().getPluginManager().registerEvents(new ClickNPC(), this);

this is the line

I k

[glossy scroll]

where is that located

[acoustic pendant]

bro

I know to read the stacktrace, i just don't know why is giving an error

[lost matrix]

Nope thats not the line. Clean compille, rerun, then show us the error and line again.

[glossy scroll]

yea

[glossy scroll]

the real issue is that listener or plugin is null

[acoustic pendant]

line 46

and then onEnable method

[glossy scroll]

not that it matterns too much, but standard practice uses Bukkit.getPluginManager

[acoustic pendant]

I've always used it like this and i got 0 errors

[glossy scroll]

it does the same thing

[solid cargo]

if sender.getName() is console, will it return a string "Console"?

[lost matrix]

When does your plugin enable? startup or postworld

[acoustic pendant]

I haven't touch that yet, so i believe startup

[lost matrix]

Are you using this plugin as a depencency for another plugin?

[glossy scroll]

        return HANDLERS;
    }```

[acoustic pendant]

no

[glossy scroll]

needs to be static

that's the issue

[acoustic pendant]

oh

yea, it enabled now, sorry I was just dumb

[lost matrix]

Btw listening to your own events makes no sense. Just keep that in mind.

[glossy scroll]

thats not really true

[acoustic pendant]

what do you mean?

[eternal oxide]

You raise the event, you get it back once its finished with. No need to listen to it

[lost matrix]

Yes. Events have a single responsibility as an api gateway. Internally using your external api is very bad design.

[tawdry scroll]

How can i change the path(local maven repo) where the buildtools deposits the appropriate jars after its done

[acoustic pendant]

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<outputDirectory></outputDirectory>
</configuration>
</plugin>

[glossy scroll]

i mean your logic is sound smile but

what if you have many different types

and they all need to do something when something happens

[lost matrix]

then you write code into methods...

[glossy scroll]

an interface yea

but it seems like a big hastle to register all these

[lost matrix]

no need to listen for events when you are firing the event yourself.
Just write code in the same place as the event is fired

[ivory sleet]

Implement your own observer pattern in worst case

Don’t use bukkit’s

Well for internal purposes

[lost matrix]

And if you use the events then you are quite limited because events should only contain strongly encapsulated data with limited access to your internals.

[glossy scroll]

yes

i agree with that

i mean in reality i dont tend to listen to my own events

i do use a common interface that has necessary methods

[opal juniper]

good

[lost matrix]

Good 😄 because doing so would be a sign of failure for your design

[opal juniper]

^

[glossy scroll]

yea now that i think about it its not something i typically do

there is old code i work with that does use that pattern, so i stick with it

[glossy scroll]

now that youve identified this im gonna make a pr to make this error more clear haha

[acoustic pendant]

a pr?

[glossy scroll]

modification to spigot

[acoustic pendant]

oh

[dawn plover]

is there an way i can give these values an color? instead of the blue they are atm

[upper vale]

the colors are from brigadier i believe

[glossy scroll]

yea that would be a bit tricky to change

[upper vale]

https://github.com/Mojang/brigadier

Lucko has a nice little utility for helping you impl brigadier: https://github.com/lucko/commodore

[dawn plover]

oh amazing

[dry forum]

is there a difference between async vs sync runnables? and why would people not just use async when theres no extra work needed for it to work vs async

[lost matrix]

Async tasks cant interact with anything from the spigot api. (few exceptions)

[dry forum]

ah so if my runnable works async with no issues would it be best to keep it async?

[ivory sleet]

doing stuff async can distribute heavy and resource intensive tasks such that they do not block code execution of more necessary stuff that needs time to compute as well, however async comes with a cost, you suddenly deal with properly updating state, making sure you don’t get indeterminacy in terms of behavior and dead locks etc, it’s a double edged sword really

[lost matrix]

No. Just because it is empirically safe for a small sample doesnt mean it is safe in general.
It really depends on what you are doing.

[dry forum]

alright thanks

[smoky oak]

ok i understand the texture part of resource packs now but how can i prevent the block update when two mushroom blocks get placed next to each other

[knotty gale]

I am using spigot 1.18.2 and the Materials "tinted glass" and "target" arent a thing ("target" is refrencing the target block, you know, the one introduced into 1.16)

I do not know why

[lost matrix]

Do you have vault as a dependency?

[quaint mantle]

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

its nto working

[knotty gale]

I need that?

[lost matrix]

?notworking

[undone axle]

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

[lost matrix]

No. But it causes such issues.

[lost matrix]

Show us your pom.

[knotty gale]

I do not use a pom 💀 (something is very wrong, I can feel it)

[lost matrix]

Not much we can do then. Make sure you imported the right libraries or whatever.

[knotty gale]

hold on, what does a pom do?

[knotty gale]

^^

[smoky oak]

it tells your compiler how to process your imports basically

[river oracle]

Please use gradle or maven it'll make your life 1000x easier

[opal juniper]

TIL you can have maven modules inside of maven modules

[knotty gale]

but does this effect the fact that the block I want to use apparently doesn't exist in 1.18.2?

[smoky oak]

uh which remapped file is the correct file again

[smoky oak]

theres an archive of 1.18 spigot docs. check the materials enum

[knotty gale]

can you send it to me?

[smoky oak]

googling is an essential skill for every programmer so no, ill just tell you it exists

[knotty gale]

ok 💀

[knotty gale]

I found it

[acoustic pendant]

why is line 48 ( the if statement) giving me an error

[smoky oak]

try !(channel...==null)

[acoustic pendant]

no, same error

[smoky oak]

might help to post said error

[severe turret]

mind saying what error

💀

we are not mind readers

except smile

[acoustic pendant]

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

[smoky oak]

its because your channel is already null

you cant call non static methods of a null object

[knotty gale]

I am fr using 1.19 and the blocks dont exist

wtf

[smoky oak]

it exists for me

Use Spigot

[warm mica]

and yes why craftbukkit

[serene egret]

followed some tutorial

[chrome beacon]

Oh no

[warm mica]

[chrome beacon]

Unofficial download

[delicate lynx]

for the love of god use buildtools

[river oracle]

I wonder if this unofficial download has malware

[chrome beacon]

If you're just downloading random stuff you will end up with malware

[river oracle]

Lmfao

@EventHandler
public void onEvent(BlockPlaceEvent e){
    e.getPlayer().sendMessage("placed block");
    if(Tag.MUSHROOM_GROW_BLOCK.isTagged(e.getBlock().getType())){
        e.getPlayer().sendMessage("placed mushroom block");
  }
}

How do tags work again? I'm placing a stem block

[quiet ice]

Does it say that it placed a mushroom block if you place mycelium?

If so, then it should be obvious what's wrong

[smoky oak]

...yes

[serene egret]

whats the official download

just googled spigot 1.12.2 and this is first

gg

[smoky oak]

since thats the only tag with mushroom in the mane imma assume theres no tag for mushroom blocks

[chrome beacon]

Read this @serene egret

[smoky oak]

is it quicker to do a hashset compare or a equals for every possible material?

[quiet ice]

?jd-s

[undone axle]

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

[quiet ice]

EnumSet would be the quickest, but it is not recommended

Hence equals

[frozen cedar]

how to put int[][] in config.yml?

when I try to add like this: [[-2, 0], [-2, 1], [-2, 2], [-2, 3], [-2, 4], [-3, 1] ] then it turns out this:

[quiet ice]

HashSet is terrible performance-wise as it needs to handle hashcode collisions

[quiet ice]

no need to double-post

[smoky oak]

why not?

[frozen cedar]

there was a mistake in the past

[quiet ice]

ah

Either way, that is the correct syntax

[chrome beacon]

It may stop being an Enum in the future

[quiet ice]

May is a kind word there, it will stop at some point

[worldly ingot]

What in the absolute fuck nuggetry is this

[smoky oak]

wouldnt i need to rewrite it either way then

[quiet ice]

It might not look pretty, but blame yaml for that

[worldly ingot]

oh it's a list of a list

[quiet ice]

not really, I am sure @worldly ingot and friends have been carefull to not break too much

[smoky oak]

no i mean

i do == Material.MUSHROOM_STEM

im accessing AN ENUM

so wouldnt it break no matter if i use equals or enumset

[quiet ice]

Not really

[frozen cedar]

or autoformatter

[quiet ice]

At that point just use json instead

[frozen cedar]

how?

[quiet ice]

org.json:json is a great library to save stuff manually

[frozen cedar]

manually?

ohshit

ok

[quiet ice]

it will likely remain a constant, so that will be valid

[quiet ice]

Well it'll look something like that:

try (FileOutputStream fos = new FileOutputStream(file)) {
    JsonArray a = new JsonArray();
    for (int[] intArray : intArrayArray) {
        JsonArray intArrayJson = new JsonArray();
        for (int i : intArray) {
            intArrayJson.add(i);
        }
        a.add(intArrayJson);
    }
    fos.write(a.toString(4));
}

[frozen cedar]

file = ?

[quiet ice]

You might not even need to write it to an output stream really, but eh

file is just an instance of java.io.File - though arguably you should use the nio utilities instead

[serene egret]

java.lang.UnsupportedClassVersionError

????????

[quiet ice]

what do you compile it with?

[serene egret]

java?

[quiet ice]

Eclipse JDT, IntelliJ artifacts (or however it is called), maven or gradle?

[serene egret]

bro i dont know

using eclipse

[eternal oxide]

IDE, maven, gradle?

exporting from eclipse?

[quiet ice]

(IDE meaning whether you use the "Export" button/functionalitiy in eclipse)

[serene egret]

ye

[eternal oxide]

check your project compliance level is also 1.8

same as workspace

[serene egret]

using project specific settings

[eternal oxide]

make sure they are 1.8

[eternal oxide]

right click your project, properties, Java Compiler

you have project specific enabled, but nothign selected

tick use compliance from execution environment

[serene egret]

cant

greyd out

[eternal oxide]

odd

what about under building?

sub set of Java Compiler

So expand Java Compiler

[serene egret]

havent touched this

[eternal oxide]

that looks fine

[quiet ice]

what is your build path?

[eternal oxide]

Java Build Path, left window

[smoky oak]

best way to check if two block instances are of the same block? Compare location or call equals?

[eternal oxide]

There is only ever one instance of a Block

You can have multiple states, but only ever one block

[smoky oak]

okay imma correct myself

[waxen plinth]

Just call .equals

[smoky oak]

whats the best way to check if the sourc block and affected block of blockPhysicsEvent is the same

[waxen plinth]

When in doubt, .equals

[wet breach]

store the source block in a object, then get the affected block and then store it in another object, then as Redempt said use .equals on the two objects

[waxen plinth]

Why do you need to store them

e.getBlock().equals(e.getSourceBlock())

Not sure if those are the actual method names but you get the point

[smoky oak]

they are

hah?

so um

placing mushroom blocks next to each other changes their texture

but apparantly the cause and affected block for those texture changes are the same

[wet breach]

You don't necessarily need to, but it is the guaranteed way to not lose the instances of those especially from events since sometimes you can grab the wrong ones. Preference most of the time

I always recommend the guaranteed ways, but overall the thing that needs to be done though is as you said, .equals

[smoky oak]

i have a lot of questions right now

[stuck flax]

event for experience orb spawn? checked google but there are conflicting answers

[wet breach]

texture changes are client side

from the servers perspective they are the same

[smoky oak]

then the state change

i dont think so

sides

[wet breach]

well one is rotated

[waxen plinth]

Yeah that's definitely stored in the block

[smoky oak]

if i add a call out it shouts out when i place another block

[waxen plinth]

It's not rotation, each individual side can be in one of two states

[smoky oak]

and says its a physics event

[wet breach]

well if its not rotation, then the direction it is facing would always be the same, but according to the screen shot they are not

[smoky oak]

im cancelling all block PhysicsEvents with the affected block being a Mushroom so why does it still change the block state on the block placed later on the right?

wait

the placed block updates its own face

why

[wet breach]

there is other events that affect block state updates

[smoky oak]

its definitively on block placement

[wet breach]

while it might be happening when you are placing a block, it doesn't change the fact there is other things that affect state updates

what you might have to do, is after you place the block, go back and reset it

after a tick or two

[smoky oak]

makes sense

whats the in line scheduler look like again?

[twilit roost]

Do filled_maps have itemMeta?

[waxen plinth]

MapMeta?

[tardy delta]

how would i go about loading an user from the database and all of its homes (two different tables: users and homes), i tried stuff with sql joins but i dont think thats what i need

im thinking about what query to use

[wet breach]

can you explain further the setup between the two tables?

you could use a join query if both tables use the same id type to identify the information in both

I mean can technically still use a join query even if that isn't the case, but becomes a bit more difficult lol

[opal oasis]

so i've been trying to figure this out all day but i cannot get an answer does anyone know how i can make a give command with amount and if its like a letter instead of a number it gives like a error?

[wet breach]

if you are making a custom give command in a plugin, you would need to parse the arguments from the command and then decide what to do if an argument isn't appropriate, in your case if a letter is given. The way you check that is test if the argument is a number, if NAN is returned(Not A Number) then you know it is incorrect

[opal oasis]

Wait currently having a malfuction in my brain. i am trying to figure out how to do that. sorry i am very tired cause my brain is out of juice

i am also quite new to coding so yeah my bad

[regal lake]

Is it possible to hook on a vanilla command ?
As example i want to broadcast a message after someone use the /weather command.

[jagged thicket]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/event/player/PlayerCommandPreprocessEvent.html

you can use this event to look for when you vannila command is used and inside that you can add your broadcast etc

[regal lake]

Nice, thanks!

[carmine nacelle]

Is it possible to copy a PDC from one one item to another?

[paper viper]

Get the persistentdatacontainer, use getKeys(), and do it manually

Using a loop

[carmine nacelle]

also need to know the type though..

so its very manual

[paper viper]

Hm one second

[quaint mantle]

I think you have to use reflection for that

[opal oasis]

i get these things. i made a few commands already. but for example like a NAN i don't get that yet

[wet breach]

you have 3 ways to do this

two of them use Java API, the third uses the apache library which is shaded into spigot

[pastel juniper]

How can I edit the result of the grind stone???

[wet breach]

give me a bit and I will show you some examples of each

[wet breach]

//using a regular expression(AKA Regex)
public class SimpleTesting {

    public static void main(String[] args) {
        String str = "123";
        boolean isNumeric =  str.matches("[+-]?\\d*(\\.\\d+)?");
        System.out.println(isNumeric);
        str = "121xy";
        isNumeric =  str.matches("[+-]?\\d*(\\.\\d+)?");
        System.out.println(isNumeric);
        str = "0x234";
        isNumeric =  str.matches("[+-]?\\d*(\\.\\d+)?");
        System.out.println(isNumeric);
    }
}

//using the Character Class
public class SimpleTesting {

    public static void main(String[] args) {
        String str = "1123";
        boolean isNumeric = true;
        for (int i = 0; i < str.length(); i++) {
            if (!Character.isDigit(str.charAt(i))) {
                isNumeric = false;
            }
        }
        System.out.println(isNumeric);
    }
}

//using Apache Library
import org.apache.commons.lang3.StringUtils;

public class SimpleTesting {

    public static void main(String[] args) {
        String str = "1123";
        boolean isNumeric = StringUtils.isNumeric(str);
        System.out.println(isNumeric);
        str = "123xyz";
        isNumeric = StringUtils.isNumeric(str);
        System.out.println(isNumeric);
    }
}

I recommend just using the Apache library as that is the easiest as well as it is shaded into spigot so might as well use it

[opal oasis]

imma look into it for a bit. thanks for putting so much time into trying to help 🙂

[crisp steeple]

public static void copyPDC(ItemStack original, ItemStack toCopy) throws Exception {
        PersistentDataContainer pdc = original.getItemMeta().getPersistentDataContainer();
        Field otherPDC = toCopy.getItemMeta().getClass().getDeclaredField("persistentDataContainer");
        otherPDC.setAccessible(true);
        otherPDC.set(toCopy.getItemMeta(), pdc);
    }

[modest garnet]

how to have multiple runnables at the same time, for example i have a Bukkit Runnable run 1m after a player dies but how can i cancel that, if there are multiple.

how do i cancel the correct one

[stuck flax]

how do I get players exp points (Tried <Player>.getExp() but it's a percentage)

[vale ember]

last answer from https://www.spigotmc.org/threads/how-to-get-players-exp-points.239171/ may be useful

[glossy scroll]

runnable#cancel

or if you use the scheduler, you can use BukkitTask#cancel

or you could have an if/else statement in the run portion that dictates if the code runs

[modest garnet]

ye but there is multiple instances of the same BukkitTask

[glossy scroll]

what do you mean?

if there are multiple instances, calling cancel on one of those instances wont cancel all of them

you need to keep track of that

[modest garnet]

ok

[glossy scroll]

i also am sensing some xy here

?xy

[undone axle]

http://xyproblem.info/

[modest garnet]

sense all u want lmfao its a help channel why u care how i ask my question

i know what im doing, infact i have done it lmfao, didnt realise there was a way to cancel specific BukkitTasks

thats all

[quiet ice]

Context is important when providing answers

I cannot count the number of times I provided absolutely stupid answers because I thought someone wanted to do something different

[eternal oxide]

same

[river oracle]

Agreed lol

[vocal cloud]

why u care cause we're providing you free help and we care because we'd prefer not to waste our time

[wet breach]

store the runnable ID when you create it

also, it would probably be better if you implemented the runnable in a class so that you can easily manage your runnables

instead of creating a bunch of anonymous ones

[modest garnet]

thats what ive done

[glossy scroll]

Bukkit.getScheduler.runTask() will give you a task object too

[glossy scroll]

🥴 this is awfully privileged of someone looking for free help. apologies for trying to make your code better

[wet breach]

then using the runnable api, you should be able to call up the runnable with the ID you have

[sacred mountain]

get can i get some help in generic java? itll be offtopic but i cant find a good answer anywhere else. basically i need a way to check if the console i'm printing something to supports ansi escape codes, or not. i've tried null checking System.console() and null checking System.getenv().get("TERM"), from a site i forgot, probs stackoverflow lmao

[wet breach]

and then set its flag to cancel, that doesn't remove it from the queue, but when it comes up to run, it just won't and be ignored

[glossy scroll]

i actually saw this in CB a bit ago

[modest garnet]

i had fixed the problem cheers for the help tho

[modest garnet]

at the end of the day as u state its "free help" which your choosing to give i want trying to be rude just more confused why u are telling me that i "asked my question wrong"

[sacred mountain]

https://stackoverflow.com/questions/41057014/check-if-console-supports-ansi-escape-codes-in-java here's the one i referenced, but it doesnt seem to work:
