Did you read the page?

I can tell not

There's a fat paragraph explaining exactly what you asked

[vital sandal]

just read it and still no idea why use injection :l

any example with the same case?

[true perch]

Is there a list of valid API-Versions? My server is running 1.19.4-R0.1-SNAPSHOT, unsure what the format looks like in the server.yml file.

[chrome beacon]

The API version would be 1.19

[true perch]

Thank you

how do i set the durability of an item?

cuz u cannot with itemmeta

[fluid river]

setDamage()

ig

[serene sigil]

cannot

[fluid river]

version?

[serene sigil]

1.16

[chrome beacon]

^^

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/inventory/meta/Damageable.html

[serene sigil]

tried that

[chrome beacon]

It does work

[serene sigil]

does nothing

[chrome beacon]

Make sure you have the right import

[fluid river]

isn't it calculated other way tho

[chrome beacon]

You shouldn't have to cast it back to item meta

[fluid river]

with +

[fluid river]

instead of -

[serene sigil]

why?

[chrome beacon]

ah wait old version

Ignore me

Was looking at 1.19 Javadoc

[regal scaffold]

If I want to make a logger file for every chat message that is sent

Do I make my ChatListener write every single log into a LogManager which saves it into a file?

[fluid river]

file for every message?

oh

mb

[regal scaffold]

Like, how can I constantly append onto a file without removing current contents

[fluid river]

ChatListener should get the data and call a Writer to write to a file

[chrome beacon]

Because you want to increase the damage to the item not decrease it?

[regal scaffold]

Yes yes ok same page, cool

[serene sigil]

ohhhhhh

alr

ill try

[fluid river]

the javadocs description might be a bit hard to understand

[serene sigil]

yes lmao

[fluid river]

why xor mojang

you can learn by coding with somebody who already has some knowledge

and by just asking questions too

for async you need to add other stuff into the event

[tawny pine]

guys this is a basic java question but how can i break from an if statement?

and continue to the rest of the code

:/

[left depot]

Put your new code on the same line as the if statement

[eternal oxide]

or move yrou code into a method so you can return when you are finished

[left depot]

Like

if {}
else {}

New Code

if i am ight

[tardy delta]

is that just an alias?

[young knoll]

Use a command framework that can register them at runtime

[tardy delta]

id just parse them myself and do some reflection with the commandmap

[echo basalt]

[left depot]

oops

[echo basalt]

get sniped

[tardy delta]

half hour now 💀

[echo basalt]

so

YML is organized in "sections" and all

[tawny pine]

Guys I'm using the code:
if (getNearestEntityInSight(p, 100).equals(null)) { Bukkit.broadcastMessage("null"); } else { org.bukkit.entity.Damageable Shot = (org.bukkit.entity.Damageable) getNearestEntityInSight(p, 100); Shot.damage(10, p);
If getNearestIntityInSight returns null it is meant to broadcast null to the server.
It still damages the entity if it is in sight and carries on with the code afterwards, but if the output is null, it doesn't carry on with the code, or output null to the server like is written.

[echo basalt]

And you can call getKeys for any given section

to get all the keys for that section

yes skull me

so if you call

config.getKeys(false) -> ["Menus"]

[mighty pier]

guys type +:skull:

[echo basalt]

but if you call

getConfigurationSection("Menus").getKeys(false) -> ["menu1", "menu2"]

So what if

You do something like

[tawny pine]

if i want to see if something returns null do i just do .equals(null) or what?

[icy beacon]

== null should be fine

[echo basalt]

ConfigurationSection menusSection = config.getConfigurationSection("Menus");

for(String key : menusSection.getKeys(false)) {
  if(!menusSection.isConfigurationSection(key)) {
    // incorrectly formatted config
    continue;
  }

  ConfigurationSection submenuSection = menusSection.getConfigurationSection(key);
  ...
}

[icy beacon]

to check for nullability

[echo basalt]

.equals() is a method that is defined on the Object class

and it's an instance menu

so it'll throw a NPE

[icy beacon]

oh true

so == null it is all the way

[echo basalt]

use ==

yeah

[tawny pine]

ah ok ty 🙂

working now

// You can open the inventory with this

Found this code on the internet just for looking, but the cmd is then ./inv?

[echo basalt]

registering commands dynamically is a whole other process

you can still make it

you're learning

[left depot]

Same, i started few days ago with Spigotdev

[echo basalt]

registering commands dynamically is a bit annoying

but it boils down to simple concepts

• access the command manager
• inject new commands into it

and maybe optionally refresh all the commands for all players

[pseudo hazel]

why do you need to register new commands dnamically?

[left depot]

atm i dont know how to link a cmd to a eventhandler

[pseudo hazel]

no , thats why i am asking

guessing is the root of all mistakes

[vocal cloud]

There should almost never be a reason to reg dynamic commands. At least the core /xyz. Sub commands are a lot easier to make dynamic

[echo basalt]

ehh

my command engine does shit dynamically

[pseudo hazel]

I see

[echo basalt]

the main thing is skipping the plugin.yml

[vocal cloud]

Dynamic as in when the server loads?

[echo basalt]

uhh

[vocal cloud]

I thought we were talking about on the fly

[echo basalt]

the server loads, I do some database stuff

and then it loads after the first tick

on the fly is a bit icky but I don't do it immediately on startup

The frog has a gun!

[novel oxide]

So, I want to optimize a plugin I am making that will only apply to a specific location. I have thought of two ways but I am wondering if there are any other ways. 1st, doing a simple check if the world or location is within the sought area of effect. 2nd (which I don't know how to do but I am thinking it would be possible) activating the event checks and commands for whenever a specified command is run and stopped at another specified command. Any ideas?

[echo basalt]

micro optimization

[novel oxide]

I feel like after a certain amount of event checkers it'd start to build up. Plus the code itself in the checkers is not opimized whatsoever ¯_(ツ)_/¯

[left depot]

3sec

[novel oxide]

Besides, any small optimization is a good optimization

[echo basalt]

not really no

[left depot]

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

[echo basalt]

premature optimization is the root of all evil

[novel oxide]

It's already made

[echo basalt]

https://stackify.com/premature-optimization-evil/

[pseudo hazel]

I would rather focus on actual optimizations rather than small baby things

[left depot]

How to link a cmd to this one

[novel oxide]

As of right now, it is implementing the 1st type I mentioned

[pseudo hazel]

what do you mean by link a command to it

[fluid river]

sheeeit

[left depot]

atm their is no way to open the menu

[pseudo hazel]

oh

create a command executor and just create the menu in there

[paper venture]

What does entity target block mean? I want to get the first block on the player sight with 15 blocks limitation, I'm using player.getTargetBlockExact(15), is it fine?

[novel oxide]

Alright well thanks I guess for the... suggestion

[echo basalt]

yes

[pseudo hazel]

but honestly, option 2 sounds like it would be worse for performance

[novel oxide]

Really? I'd think the opposite. You'd use a plugin like world guard or something to run the initial command and only apply to that specific player initiator.

[smoky adder]

how do i execute a command when the player clicks on slot 0 position? I tried with event.getSlot() == 0 but it works only if I open the inventory and click with the mouse arrow..

[novel oxide]

Actually wait, can you attach event handlers to specific players outside of running them on every player and doing a check for UUID, username, or any check in general?

[tall dragon]

uhhh no

[eternal oxide]

bad idea

[tall dragon]

i mean u can. but u'd have to make ur own system and you would still just be filtering for which players to trigger an event

[novel oxide]

Damn, that'd suck. Guess I'll just stick with what I have now. I'm already doing short-circuit with the first if statement being the world check

[pseudo hazel]

how else can a player click on the slot if not with the mouse cursor?

[tall dragon]

but did u even do any benchmarks?, is ur code really performing that poorly?

[novel oxide]

It's not, but I have only tested it on my dev server and not the actual server yet

[tall dragon]

shoulnt you create some timings reports while using your plugin then?

[young knoll]

Pov of their servers:

https://tenor.com/view/sparks-electrical-electricity-equipment-radio-amateur-fire-gif-24123123

[tall dragon]

or run some spark profilers

[novel oxide]

Oh my god, I never knew that was a thing

[smoky adder]

I mean when the player right clicks on whatever item is in inventory position 0

[novel oxide]

The more you know

[pseudo hazel]

and why didnt your approach work?

[smoky adder]

like when you enter the hub and click on the compass in your inventory to open the menu

[rotund lotus]

Hey Guys. Looking for a bit of advice on the best way of going about developing a custom world generation system. I'm looking to emulate similiarly what origin realms do, where users can create a 'realm' and build in a 1000x1000 area that is generated. I'm fine with that, however what would be the best way of doing this? I see on origin realms, they have created a world with a UUID for each realm, I would have thought it made more sense to have a world with multiple 'realms' on it. Is this efficient? loading, unloading worlds as players teleport to their own.

[true perch]

What's a quick way to add color to text?

[pseudo hazel]

ChatColor.GREEN + "text"

[jagged bobcat]

I'm getting error java.lang.IllegalArgumentException: Unsupported class file major version 63 when trying to shade my plugin. Is there a reason why I am getting it?

[smoky adder]

why should i use a getItemInHand but i want whatever item is in slot 0 when i right click execute a command

[tall dragon]

depends on how big ur playerbase is tbh

[pseudo hazel]

I never said anything about a hand, I said why didnt youir approach work, event.getSlot() == 0?

[quiet ice]

There is greater potential of better ticking performance when using different worlds

[kind hatch]

Depends on setup. If they use SlimeWorlds, then yes, it's far better for each of them to be loaded individually. Otherwise, you could probably load a "cluster" of realms at a time.

[rotund lotus]

well, origin realms seem to be able to do with 400~ players. Guessing they have some way of storing a world in a database, as I don't think flat file with that many worlds makes sense

[tall dragon]

if its pretty big best course of action would probably be to have an automatically scaling networks that starts up mini servers as they are needed acting as the players realm

similar to hypixel handles their islands

[true perch]

How do you give text a color based on a hex value?

[kind hatch]

ChatColor#of()

[true perch]

Thank you

[rotund lotus]

I thought this also, but it seems they run it all on one instance which is impressive

or maybe I'm wrong

[tall dragon]

they probably have some very impressive hardware then. but i dont have any knowledge of their actual hardware

[kind hatch]

Their islands are probably on a separate network with some scaling infrastructure.

[tall dragon]

probably yea

using slimeworlds might not be viable

if 400 worlds are to be loaded into memory

even if they are only 1k by 1k

[echo basalt]

hypixel has a proprietary very shitty scaling system

[kind hatch]

It's better than 400 normal worlds though

[tall dragon]

thats alot of data

yea, very true

[echo basalt]

from what I've understood from my interviews

they run a mini server with all the plugins and just toggle them off depending on what's being played

[kind hatch]

Their slime world tech is pretty cool though.

[echo basalt]

slime worlds are cool but it's more of a fancy proprietary system to save a lot of disk space

[smoky adder]

because event.getSlot() == 0 it works only if your inventory is open, it doesn't work when it's closed, btw I was trying to make a plugin similar to ItemJoin and in the config file I put a config part for each slot so slot1: name,material,lore,command But I can't execute a command when player click on that slot

[echo basalt]

they also have this thing where you can paste a structure anywhere n shit

and spin up tons of new worlds

[young knoll]

💀

[kind hatch]

Well it's not really proprietary anymore. :p

[tall dragon]

i loved reading about their replay system

very interesting read

[young knoll]

Why don't they just deploy the plugins they need when the spin up a server

[echo basalt]

because it's legacy code

that they can't bother maintaining

[kind hatch]

Their process for things is pretty cool. So I find it hard to believe that they would just disable certain plugins instead of just using a template or selecting the plugins they need.

[young knoll]

My favorite

[tall dragon]

find that pretty weird too

[echo basalt]

it's a very old legacy system

[pseudo hazel]

cannot execute command when player clicks on item

[echo basalt]

made back in like 2014 iirc

[young knoll]

I'm willing to bet hypixel has a large amount of jank going on behind the scenes

[true perch]

ChatColor#of(), I can't find the of method anywhere

[echo basalt]

there is some jank

[kind hatch]

Probably, but what company doesn't? lol

[tall dragon]

i mean to be honest, what big network doesnt

[echo basalt]

there is also a bunch of cool shit

[kind hatch]

Are you using the bungee import?

[young knoll]

Something can be both cool and jank

[true perch]

I am not.

[kind hatch]

That would be why

[true perch]

I plan to implement bungeecord though

Same thing?

[young knoll]

You pretty much always want the bungee ChatColor now

[kind hatch]

Sort of. The ChatColor api is just available in the spigot api.

[rotund lotus]

https://www.spigotmc.org/resources/slimeworldmanager.69974/ is this what you guys are talking about?

[kind hatch]

So there's no downside to using it.

[young knoll]

I'm surprised the bukkit one isn't deprecated

[true perch]

😅

[kind hatch]

Yes, but that is someone's implementation of the underlying tech. You could probably use that though.

[young knoll]

That's not the spigot API

[kind hatch]

Do you know why we don't use the bukkit one anymore? Why did everything except #stripColor() get added to the bungee one?

[true perch]

import net.md_5.bungee.api.ChatColor; fixed the import

[rotund lotus]

i'll look into it and see what it's doing before that, thanks for advice guys

[rotund ravine]

Hexxxx

[kind hatch]

Yea, but why does all the new stuff get added to the bungee import instead of the bukkit one?

[young knoll]

Yeah hex isn't in the bukkit one

[kind hatch]

I just don't fully understand the rationale behind it.

[young knoll]

Idk

Spigot also still maintains separate patches

¯_(ツ)_/¯

[pseudo hazel]

because the bungee one is just more up to date

[kind hatch]

It just seems inconsistent is all. I mean, we use the Spigot API to develop but most of the imports are from Bukkit and the only time we need to use chatcolor, we now have to use the BungeeCord API to do so. It's just weird to me.

[pseudo hazel]

thats true

idk either

[smoky adder]

I have a configuration for each slot in the config file: slot1: name, material,lore slot2: ... How do I add a command: example command to execute a command when I right click on a certain slot?..

[kind hatch]

Add a section for commands?

[smoky adder]

yes, but how do I understand the item I'm holding? this can change according to the configuration as i assign the command ??

[kind hatch]

Configurations are held in memory so once it's set, you'd have to either restart or reload the configuration for anything to be changed.
Secondly, clarify something. Are you talking about an item in a GUI or an item the player is holding in their hand?

[smoky adder]

an item the player is holding, such as itemjoin

[kind hatch]

I'm assuming that you already have item checks in place to determine that the item the player is holding is the one that matches in the config,
You'd only have to add some code to execute the commands if the item matches.

[smoky adder]

and just what you said i can't do...

[kind hatch]

So you want to know how to do the item checks?

That message is in the spigot.yml

[smoky adder]

yes, I'll send you the code so you can see how I did it, each slot has a piece of code that takes the content of the strings in the yml file

would you know how to do it?

[kind hatch]

Manual file read? I don't think there is an api method available to change it. So you're left with the yaml file import.

File spigotYML = new File(<Server Directory>, "spigot.yml");
FileConfiguration spigotYMLConfig = YamlConfiguration.loadConfiguration(spigotYML);

spigotYMLConfig.getString("messages.unknown-command");

[weak meteor]

i think this is good

for me, at least 🙂

[kind hatch]

You just need some simple checks then. You already have your criteria, you just need to verify it.
ItemMeta#hasDisplayName()
ItemMeta#getDisplayName()
ItemMeta#hasLore()
ItemMeta#getLore()

You'll need to check if the item has those properties first, then you can compare with the getter methods.

[haughty storm]

I want to add an item to a chest once it gets generated. I have this code
https://paste.md-5.net/powirahuco.cs

But I get a ClassCastException
https://paste.md-5.net/inifojemuk.pl

Line 45 is

Chest chest = (Chest) state.getBlock();

[smoky adder]

the problem is that i can't match because the name of the object can be changed at any time as well as the lore ecc from the config file

[kind hatch]

Well, that's to be expected. Are you wanting the item to persist even if the data changes?

[smoky adder]

if in the code I put the object in the first slot has the name "hello" and then change the name to game it will give an error

[kind hatch]

?paste your code

[undone axle]

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

[eternal oxide]

you cast the state not the block

[smoky adder]

Yes wait 10 minutes pla

[haughty storm]

Sorry, I don't understand what you mean. I am getting the block from the BlockState and cast that Block to a Chest

[kind hatch]

You don't cast to a block though. You cast to the state. So just Chest chest = (Chest) state;

[haughty storm]

ah ok, I'll try that Thank you

[serene sigil]

how to manually make an item break?

[paper venture]

The question is not about minecraft but about the java. Today I learned about Function Consumer and Supplier, so is there any need in custom functional interfaces when you can always use existing ones?

[haughty storm]

I don't get an error anymore but the Item isn't put into the chest

[obsidian plinth]

i need to detect what painting a played based is that a thing

[paper venture]

Maybe if the method should take a lot of parameters it's okay. But if the method takes only one parameter...

[kind hatch]

I could be wrong, but I don't think chests generate with loot anymore. The loot should now be generated upon first open using LootTables.

[haughty storm]

And do you know if there is an event for when the loot generates?

[true perch]

How do I pass in the main class to an enum class without storing the main class as a static instance?

[kind hatch]

There is a LootGenerateEvent.

[haughty storm]

ah, thank you

[ivory sleet]

yes

[true perch]

Is it possible?

[twin crater]

what do you wanna do?

[smoky adder]

@kind hatch https://paste.md-5.net/ikulivodes.pl this is the code

[true perch]

Store NamespacedKeys as enum objects

which requires a reference to the main class

[sterile token]

I have exactly the same question, when you are you doing DI, how do you pass Main class instance into utilities? So far utilities musnt be initialized

[true perch]

Yeah basically the same

[kind hatch]

Now why do that when you can instead make them public static final in a util class?

[eternal oxide]

utilities should not be an intialized class

[sterile token]

Yes but what if you need a main class reference?

[kind hatch]

The keys will never change anyways

[eternal oxide]

not unless it's a static singleton

[true perch]

That could work. I could store the keys in a Util class as public static final

I like that

[sterile token]

Let me type an example what i mean

[obsidian plinth]

i need to detect what painting a played based is that a thing

[sterile token]

How would you get the config instance from main class ? without doing a shity static getter for the instance

public enum Messages {
  
  private Config config; 

  PREFIX(config.getString("General.Prefix")),
  INVALID_USER(config.getString("Messages.Invalid.Sender"));

  @Getter private final String text;
  
  Messages(String text) {
    this.text = text;
  }
}

[smoky adder]

.

[twin crater]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/Painting.html probably somthing with art

[kind hatch]

Painting#getArt()
You'll have to get cast the blockstate, but you can def get the painting value.

[serene sigil]

?

[tender shard]

Paintings are entities, not blocks

[sterile token]

All mc thing are entities ¿

[true perch]

Is there a way to do this without making the main class a static reference?

[tender shard]

No

Blocks are not

Neither are chunks nor worlds or particles

[eternal oxide]

you could try using JavaPlugins getPlugin

Entity is every object which represents a model?

[kind hatch]

Dependency Injection if you wanted to go that route.

[tender shard]

Entities are everything that extends the Entity class

[sterile token]

But what about if its not the default config, custom class let say?

[sterile token]

Oh you are talking about mc entities, because entities in programming doesnt mean that

[tender shard]

Yeah i just wanted to say that BlockPlaceEvent won‘t work for paintings lol

[true perch]

Seems I can't quite get it right 🤔

[sterile token]

I always have that confuse tho my bad alex

[kind hatch]

Well, if you use DI, then your variables can't be static.

[twin crater]

yea dont instantiate a util class

[tender shard]

Make the key not static, but create it in the constructor

[sterile token]

But how you pass the main class instance? If you cant initialize it?

See my example for asking

[sterile token]

this

[tender shard]

A utils class shouldnt need an instance. Just store the keys in the main class

[kind hatch]

Then it has to be a static instance. There's really no way around that.

[serene sigil]

can some 1 help?

[young knoll]

Set it to null and play the break effect

[sterile token]

Isnt not good doing static getters for instances?

[serene sigil]

yes, but isnt there a method for it?

[kind hatch]

As with everything, it depends.

[sterile token]

I mean i just wanna learn because i dont like that ugly getter

When ever i need to code over a code they provide and it contain a static getter for instance i prefer to reject it

[weak meteor]

I have this abstract class and i wanna call it in another class, the purpose of this is: if i extend this class just make the getFileName method and bc it is extended i dont need to make more methods, right?

the other class:

[tender shard]

Correct

[kind hatch]

yes

[weak meteor]

so

i wanna call it in main

error

[sterile token]

UsersConfig should be better naming and also following the naming convention

[weak meteor]

yes i know

[twin crater]

well, since you shouldn't instantiate a util class, theres no other way

[weak meteor]

srry

[tender shard]

You didnt declare any load() method

[kind hatch]

Either you think it's static, (which it's not) or that method isn't public.

[weak meteor]

yes, i thought that, so what happens if i make it static

[terse ore]

u changed your pfp

[tender shard]

Also why is that class name in lower case

[sterile token]

load() is a method provided from YamlConfiguration

[weak meteor]

error

[tawny pine]

guys im using this code:
}.runTaskTimer(MinecraftPluginJava, 5, 1);
it says to reference your plugin as the first parameter, should i just put my plugin name? for some reason it doesnt accept this

[kind hatch]

What class is that in?

[weak meteor]

thats in the abstract

[terse ore]

the instance

[weak meteor]

class

extending YamlConfig

[tender shard]

You still confuse class names wirh instances

[tawny pine]

oh so i have to make it an instance before i do?

[tawny pine]

ah ok no dw i gotcha

[terse ore]

for example

[tawny pine]

ty 🙂

[tawny pine]

wait no it didnt work whats the example sorry?

:/

🙂

[terse ore]

you can make a getInstance() method in your main plugin class

that returns the plugin instance

[smoky adder]

Plscan you help me?

[terse ore]

and then do YourMainPlugin.getInstance() to access the instnace

[twin crater]

your Main class is extending JavaPlugin. You must pass an instance of this

[tawny pine]

what would that method entail?

[terse ore]

wdym

[kind hatch]

What part of this isn't working? Because although hard to read, it looks like everything is working as intented.

[tawny pine]

i mean how would i make that method?

[weak meteor]

So?

what to do

[terse ore]

public class Main extends Java {
private static Main instance;

public void onEnable() {
isntance = this;
}
public static Main getInstance() {
return instance;
}```

[tender shard]

https://blog.jeff-media.com/getting-your-main-classes-instance-in-another-class/

[smoky adder]

@kind hatch do you remember the speech from before??

[kind hatch]

You should be able to access that method so long as you are extending it in another class. How are you creating the users class? (Which should be uppercase btw)

[weak meteor]

normal class

like New Java Class

Class

[smoky adder]

.

[kind hatch]

I don't fully understand then. If someone changes the name, then that's the user's fault. If you want to make it so that the item works regardless of name changes, then you need to put special data in the PDC of the item and compare against that.

[eternal oxide]

?paste

[undone axle]

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

[eternal oxide]

@sterile token if you really desire an enum wrap it in a class, like so https://paste.md-5.net/udigecadog.java

[tall dragon]

any1 know what this is?

"new fast maven import"

[eternal oxide]

that allows you to initialize your class while keeping the enum

[kind hatch]

You can also use the JavaPlugin#getPlugin in an enum if you really needed to.

[eternal oxide]

yep.

[kind hatch]

Are you giving the player items when they join?

[smoky adder]

when i in slot1 configuration then slot1: name:"test" material:"test" i also want to add command: "kill test" for example. So I want to connect the content of the command string with the object which is in slot 1 so that when the player clicks the object which is defined in slot one he executes the command which is assigned in the slot. at least i can't find a way to merge these yml files and code

[eternal oxide]

The above evample you can fetch keys with RecipeManager.RECIPIES.ZOMBIE.getKey();

[smoky adder]

yes

[sterile token]

I wil ltake a look

[kind hatch]

Ok, then forego the item name and lore checks and instead use the PDC to assign custom data. That way, you won't have to worry about players changing the item name.

[smoky adder]

can you give me an example of how to do it?

[kind hatch]

@tender shard I forget, do you have a PDC tutorial on your blog?

[tall dragon]

https://blog.jeff-media.com/persistent-data-container-the-better-alternative-to-nbt-tags/ prolly this

i guess?

[kind hatch]

@smoky adder Use that link ^

[smoky adder]

ok thanks

im in 1.12.2

and the server is in 1.8.9 it works

[kind hatch]

Then you'll have to use NBT instead.

[tall dragon]

why would u program on 1.12.2 if the server runs on 1.8.9 tho

[kind hatch]

Otherwise, tell your players not to rename those items.

[tall dragon]

u only risk shit not working for no reason

[rough ibex]

moreover why are you on 1.8 at all

[smoky adder]

I don't know since the plugin works in server 1.8.9 even if and 1.12.2 I think up to that version it is compatible

[obsidian plinth]

thank u i couldnt find that doc on google

idk why

[twin crater]

ehm well, it will work it 1.12.2 but if you use anything from 1.12 and try it on your 1.8. server it will stop working. there are ways to make it compatible for multiple "major" versions but i am not the right contact for that 😄

[sterile token]

Dont critize people using legacy versions we are all free to use the versions we want. But then we cant complain about issues or bugs that must be solved on own

[cunning pendant]

word.

[sterile token]

?

[kindred valley]

Why are you this angry

[sterile token]

I have the perfect answer and well explained, let me translate it

Sorry if i sound rude on the text but is the truth

[kindred valley]

You needda calm down

[sterile token]

I mean i have seen this situation related to legacy since i join this community

Its really bad that people oblise you to use ewer versions

[cunning pendant]

it means I agree with you

[tall dragon]

what are u talking about, there is nothing wrong with his message

[round finch]

salty?

[twin crater]

wrong chat guys ❤️

[round finch]

yes #general

[kindred valley]

Extraordinary stuff going on.

[sterile token]

It is really annoying this situation of the versioning issue, since they are there to use them and everyone is free to choose the one they want. But then I would not have the right to come to complain because certain things do not work or ask for support itself. Maybe someone will help you, that's the good thing. Basically it is supply and demand, if there were still no people requiring legacy plugins there would be no developers programming them.

Translated with www.DeepL.com/Translator (free version)

[kindred valley]

What if i come this server for help regarding minecraft version 1.5.2. Is it usual?

[granite owl]

why would ppl fight over using different versions of an api exactly?

xD

[tall dragon]

u could try

probably wont get much response

but i woulnt be angry at you for trying.

[sterile token]

Im trying to find that answer haha, i dont understand why people get mad when using legacy versions because there is nothing wrong with them

.

For me it is something related to consumerism. Because I have seen 1.8 programmers making over $100 (usd) in really simple commissions. But in 1.19 on the contrary they pay you less, because supposedly the api is better

[kindred valley]

I get you mate yeah

[kind hatch]

I think there's a stigma around using legacy code. As developers, we are drawn towards using the latest and greatest. The same applies to minecraft. People usually want what's in the newest updates and developers have to follow with them. So when the majority is using the latest, it gets annoying to try and backport features that clearly can't work on older versions.

[eternal oxide]

They are paying 1.8 devs more because it's harder to find a 1.8 dev. You can demand more money.

[granite owl]

id just ignore hate tbh xD

[sterile token]

I totally agree with your point, but there is no need for being rude with those using legacy versions

[granite owl]

just my suggestion i learned to absorb criticism and filter/+ ignore toxcicity

unless its towards beginners xD

then i dont ignore it

[kindred valley]

Hello elgar

[sterile token]

As when they go around annoying, the one who gets angry loses. It's something you learn a long time ago, you have to ignore simply because it's worse if you play along.

[granite owl]

u know what ppl hated me on for?

[sterile token]

Im not really sure if you can explai nit

[granite owl]

im translating my native c++ library to work with different languages ```csharp
public string GetFileExtension()
{
if (IniParser.m_pIniParser_getFileExtension != nullptr)
{
unsafe
{
string? str = Marshal.PtrToStringAnsi(((delegate* unmanaged[Stdcall]<IntPtr, IntPtr>)IniParser.m_pIniParser_getFileExtension.ToPointer())(this.m_pIniParser));

            if (str != null)
            {
                return str;
            }
        }
    }
    
    return "";
}

why are you using unsafe contexts, why are you using pointers, this is c#, why are you using delegates, just scrap your project its useless blablabla

when i literally explained this before ```txt
im translating my native c++ library to work with different languages

once i finished this, ill make my lib work for java and to that extend spigot

[granite owl]

so yea^ xD

[sterile token]

For me is still being consumism

[kind hatch]

You mean consumerism?

[regal scaffold]

Hey, I was directed to AsyncPlayerChatEvent to see how a event could be called Async

[sterile token]

yes my bad* its diff world for me

[granite owl]

wdym

[regal scaffold]

But I can't seem to figure out how to mirror the implementation or what part allows it to be async

I want my custom event to be able to be called async

https://hub.spigotmc.org/stash/projects/SPIGOT/repos/bukkit/browse/src/main/java/org/bukkit/event/player/AsyncPlayerChatEvent.java#26,40

[granite owl]

isnt player chat running on a different thread altogether?

as such being async

or wdym

[regal scaffold]

Yes

[twin crater]

yea

[regal scaffold]

And calling a event that's sync from a async thread isn't possible

So I need to make my event support async

[granite owl]

write an interface

that is thread safe

let ur async event populate it

and let ur sync thread fetch it

basically uni or bidirectional populating with commands and fetching

[rotund ravine]

It’s just calling super(whatever, true) in the constructor

[granite owl]

but im still not entirely sure if i got ur question right

[regal scaffold]

Oh yeah lol I just looked at Event class

[granite owl]

kekw ```txt
(process 1776) exited with code -1

[regal scaffold]

I'm trying to use FileHandler to be able to write log-type messages to a file but getting some weird errors

[granite owl]

great now my minecraft launcher keeps crashing with the error msg failed to update launcher all of a sudden

[regal scaffold]

.txt.lck

        FileHandler fileHandler = new FileHandler(file.getPath());

This line says a file with whatever.txt.lck does not exist:

1. The line above makes a new file called whatever.txt not whatever.txt.lck and I checked that the path wasn't wrong
2. I think maybe using FileHandler is not the correct approach

[kind hatch]

Is that a lock file?

[regal scaffold]

Uhhh asuming I don't know what a lock file is I'm gonna say no

        file = new File(plugin.getDataFolder(), "logs/" + uuid + ".txt");
        FileHandler fileHandler = new FileHandler(file.getPath());

I think indeed FileHandler is not the right thing for this

Maybe BufferedWriter

[rotund ravine]

Why are you even using s filehandler

Why use .txt files too

[regal scaffold]

I looked online and said it was a decent option

[ivory sleet]

a file lock is a mechanic to ensure one process at a time can write/read to the file

[regal scaffold]

But they tend to use it with a logger

[regal scaffold]

Interesting

Ok ok I'm gonna switch to bufferedWriter since it's a log-system it should constantly write

[kind hatch]

Isn't BufferedWriter the default recommendation for that?

[rotund ravine]

Prolly

[regal scaffold]

Wasn't when I searched but now I will use it

[ivory sleet]

buffered writer is buffed at writing ye

[ivory sleet]

lmao

[kind hatch]

lmao

[regal scaffold]

I mean does the extension of the file really matter?

I could just call it .log

[ivory sleet]

well

[granite owl]

is anyone else having problems with their mc launcher rn?

[regal scaffold]

Doesn't make much of a different right? I could literally make it .thisisalogfile

[kind hatch]

It would be better if you had a standard extension though.

[ivory sleet]

.log is for informative purposes

[rotund ravine]

Well what sort of logs are you storing?

[regal scaffold]

Yes that is of course correct

Lets say I'm storing

Chat messages

Called by an event inside my plugin

So obviously I think .log is the right way

[rotund ravine]

Why not use a database or some cool format like json

[regal scaffold]

I could but

Logs are specific to a object

[kind hatch]

.log will work just fine.

[regal scaffold]

I feel like having 1 long log file is worse

Than being able to straight up separate it by objects

[kind hatch]

File extensions are mostly arbitrary. On UNIX systems, it doesn't matter what the file extension is. The file contents determines the type

[regal scaffold]

So you can straight up see the logs for a individual object

Thought so, thanks for the help guys

[rotund ravine]

You can have more json files.

[regal scaffold]

Why would I chose json over just... text tho

Is there a specific?

Besides maybe future readability

[kind hatch]

I guess parsing for statstics.

[rotund ravine]

Why not? Easy to decode and encode.

[regal scaffold]

It's an extra step tho for something that might be writing into the file 2-3 times per second

I guess making a cache is also smart

But yeah, i got the idea now

[rotund ravine]

JSON is a lightweight data interchange format that is easy for humans to read and write and easy for machines to parse and generate. JSON is a text format that is completely language-independent but uses conventions that are familiar to programmers of the C family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and many others. JSON is a better choice than plain text because it provides a standardized format for structuring data and almost every programming language can parse it

[regal scaffold]

Chatgpt but yes, I do agree with that

I will probably end up doing it with json

Now I have one last qustion

[kind hatch]

Unless you plan on doing anything with the logs, like statistics, then it doesn't matter how you store it.

[regal scaffold]

Using FileHandler like before, you could set a formatter

[rotund ravine]

Shush. Json superior

Formatter as in?

[regal scaffold]

Like for example

SimpleFormatter formatter = new SimpleFormatter(); 

Instead of that I assume I make my own format for the message before it's written

[rotund ravine]

Yah. Just setup your json encoder and decoder

You can tell it how to store as well as how to read.

[regal scaffold]

👍

Thanks

...

        file = new File(plugin.getDataFolder(), "logs/" + uuid + ".log");

Since when does this not create the file

If it isn't there

[rotund ravine]

Forever.

[regal scaffold]

tf

[kind hatch]

You have to call #createFile()

[regal scaffold]

What

        File phoneDataFile = new File(plugin.getDataFolder(), "phoneData/" + phone.getPhoneUUID() + ".yml");

I'm using this literally 1 class above and it creates the file if it isn't there

[kind hatch]

Could you imagine what would happen if it created a file every time you initialized the class?

[regal scaffold]

I could've swore it was

Load if exists, create if not

[rotund ravine]

Are you saving a yaml later?

[kind hatch]

It's just the former.

[regal scaffold]

        File phoneDataFile = new File(plugin.getDataFolder(), "phoneData/" + phone.getPhoneUUID() + ".yml");
        phoneData = YamlConfiguration.loadConfiguration(phoneDataFile);
        phoneData.save(phoneDataFile);

Yes

Is that why?

Damn, interesting

[rotund ravine]

Yes

[kind hatch]

The Yaml implementation that spigot has is all loaded into memory. You have to write it if you want it to persist.

[regal scaffold]

Learn something new every hour, good philosophy

[rotund ravine]

A file is just a pointer

[kind hatch]

Is that why it's never null?

[rotund ravine]

What’s never null?

[kind hatch]

The File object

[regal scaffold]

It says it's nullable

When you read "Then the new file is created" instead of "then the new file instance is created"

Makes sense now

[rotund ravine]

I mens ur literally creating an object

Why would it be null

[kind hatch]

Because there's a difference between declaration and initialization.

[regal scaffold]

So wait let me understand something about File then

        file = new File(plugin.getDataFolder(), "logs/" + uuid + ".log"); <--- Path to the file, can exist or not
        if (!file.exists()) { <--- Check if there is a actual file here
            file.createNewFile(); <----- Create the file
                                  <----- I still need to load the file again  like the first line?
        }

[rotund ravine]

It’ll just be a file instance representing nothing. It won’t be null

[rotund ravine]

It’s a pinter

Pointer

It doesn’t load shit

[kind hatch]

#createNewFile returns a boolean. It won't create anything if it already exists.

[regal scaffold]

Yeah but IJ said

Result of file.createNewFile() is ignored

[kind hatch]

That's because it returns a boolean.

It's not a void method.

[regal scaffold]

Oh... bruh

[kind hatch]

It returns whether or not it was actually able to create the file.

[regal scaffold]

Yes yes you're right, I just understood what it said

According to Google's Java Style Guide, you should use the prefix form of the increment operator (++i) in preference to the postfix form (i++)¹.

The reason for this is that the prefix version (++i) can be more efficient than the postfix version (i++) because it avoids the overhead of creating a temporary variable.

[quiet ice]

If I had to guess it is more of an error-avoidance mechanism. A loop like

int x = 0;
while (x < 10) {
    x = x++;
}

will loop ad infinitum.
But

int x = 0;
while (x < 10) {
    x = ++x;
}

not.

[fluid river]

does i++ really create a temp variable?

[tardy delta]

bing gives weird answers

[fluid river]

i thought processor/ASM just uses some command for incrementation

[quiet ice]

On a bytecode level probably. On a JIT level? Unlikely.

[round finch]

create folder

[quiet ice]

And with temporary variable I mean like pushing an element to the operand stack

[rotund ravine]

Not what the styling guide says 🤷🏽‍♂️

[quiet ice]

Not a fully-fledged LVT var

[rotund ravine]

Go yell at google

[fluid river]

oh it might be
LOAD_FAST i
LOAD_FAST a
and
TRUE_ADD a

or smth similar

that's python dis, not real instruction

[rotund ravine]

Yes, it does matter if the JIT optimizes the bytecode. The JIT compiler can optimize code by removing unnecessary operations and simplifying expressions. In some cases, this can result in the postfix form of the increment operator being optimized to the prefix form². However, it is still generally recommended to use the prefix form of the increment operator (++i) instead of the postfix form (i++) because it can be more efficient than the postfix version as it avoids the overhead of creating a temporary variable².

Source?

Chat GPT seems to have made that up

[rotund ravine]

It links to the ibm post

[round finch]

file.getParentFile().mkdirs();
file.createNewFile();

[quiet ice]

You know what? Let's test it for ourselves

[regal scaffold]

In python one can make a string using

 whatever_string = f'This string has {variable_number} numbers'

What's the alternative for something easy to build strings in java

String builder and just have 10 appends?

[tardy delta]

String.format or String#formatted

"this string has %s numbers".formatted(num) or whatever placeholder

[regal scaffold]

String format is annoying a bit

Yeah

[tardy delta]

we are getting string templates or smth (forgot what its called)

[regal scaffold]

?!/

Finally

[rotund ravine]

Eh str substitutor is similar from some library

[regal scaffold]

String.format it is

cba

[tardy delta]

but the syntax is weird

[rotund ravine]

But well, it’s not the same at sll.

[quiet ice]

Prefix:

         0: iconst_0
         1: istore_1
         2: iload_1
         3: ldc           #7                  // int 1000000
         5: if_icmpge     26
         8: getstatic     #8                  // Field java/lang/System.out:Ljava/io/PrintStream;
        11: iload_1
        12: invokedynamic #14,  0             // InvokeDynamic #0:makeConcatWithConstants:(I)Ljava/lang/String;
        17: invokevirtual #18                 // Method java/io/PrintStream.println:(Ljava/lang/String;)V
        20: iinc          1, 1
        23: goto          2
        26: return

Postfix is exactly the same. For

class TestPostfix {
    public static void main(String[] args) {
        for (int postfix = 0; postfix < 1_000_000; postfix++) {
            System.out.println("postfix: " + postfix);
        }
     }
}

[regal scaffold]

Gonna be honest I don't like python

[rotund ravine]

Use kotlin 💪🏻

[tardy delta]

https://openjdk.org/jeps/430

[regal scaffold]

But jesus the python one is clean

Being able to do functions/variables inside { }

Is so nice

[quiet ice]

If I had to guess javac will optimize any postfix operation that can be compiled down to iinc to use iinc (which basically is the prefix variant)

[hard socket]

how do I make this file be in plugins folder when plugin starts

[scarlet kelp]

Hi guys, Im trying to make server like bhop or surf servers in cs, I mean passing maps and be able to vote for the next one. So the problem is that one map using command blocks can affect another map. So I think it's a good idea to just unload rest of maps (Server.unloadWorld) when map changing, but the problem is that for some reason bukkit won't allow to unload maps which have dimension = 0 (Overworld), I found out it from source code. Have you any ideas how to solve that?

[tardy delta]

put it in your jar

[rotund ravine]

Include in the jar

[quiet ice]

So whatever but it seems that ChatGPT clearly does not know what it is saying

[rotund ravine]

Then just do saveResource(whatever, false)

[tardy delta]

chatgpt didnt know what it was saying when i let it wrote assembly either

[rotund ravine]

It used what some other noobs said in other places haha.

[quiet ice]

No - it made up it's own sources

[misty current]

i'm making a multi module project to make a plugin compatible with different nms versions and i'm getting some compilation errors because of different java versions of the spigot dependency when compiling. Can anyone help me?

  bad class file: C:\Users\kill05\.m2\repository\org\spigotmc\spigot\1.19.4-R0.1-SNAPSHOT\spigot-1.19.4-R0.1-SNAPSHOT.jar(net/minecraft/network/NetworkManager.class)
    class file has wrong version 61.0, should be 52.0

[quiet ice]

I grepped it's referenced sources and it does not mention it

[rotund ravine]

Oh well tiip

[quiet ice]

The issue with ChatGPT is that it will make up it's own sources once you ask for verification.

[rotund ravine]

Riip

[quiet ice]

Or rather said it will use unrelated sources

[hard socket]

its not loading

[rotund ravine]

Bing was supposed to be better 🥲 Well it’s good for some things.

[rotund ravine]

Did you use saveResource?

[quiet ice]

That IBM document has nothing to do with prefix/postfix incrememnt but rather JIT optimisation (and deoptimisation) in general

[tardy delta]

bing is just, here you have some small info and here are the sources, go figure it out yourself

it doesnt really get deep

[hard socket]

wdym

[rotund ravine]

🥲 I am going to bed

Someone else will explain it to you

[tardy delta]

gn

[tardy delta]

plugin.saveResource("file.png")

[quiet ice]

(or this instead of plugin if you are within your JavaPlugin class)

[tardy delta]

or no this :)

[quiet ice]

(and not using static methods)

[young knoll]

this.getPlugin(MainClass.class).saveResource
:D

[tardy delta]

we arent the first of april anymore

[regal scaffold]

Uhhh

        BufferedWriter writer = new BufferedWriter(new java.io.FileWriter(file, true));
        writer.write(message);

I see this doesn't include a next line character every time

[misty current]

can anyone help me with that

[tardy delta]

Files.newBufferedWriter

[regal scaffold]

Do I really need to add the endLine each?

[regal scaffold]

Oh will change that too

[misty current]

i don't know how i'm supposed to make a plugin compatible through versions 1.8 to 1.19 by using the same java version

[young knoll]

I think you have to compile for java 8

[tardy delta]

musnt you use the lowest java version, not sure if you can set java version per module

[regal scaffold]

        writer.write(message);
        writer.newLine();

[young knoll]

no writeln?

Sadge

[misty current]

i'm compiling for java 8, but maven doesn't like me compiling to java 8 with a dependency from java 17

  bad class file: C:\Users\kill05\.m2\repository\org\spigotmc\spigot\1.19.4-R0.1-SNAPSHOT\spigot-1.19.4-R0.1-SNAPSHOT.jar(net/minecraft/network/NetworkManager.class)
    class file has wrong version 61.0, should be 52.0

[rotund ravine]

@tender shard ^

[tardy delta]

what are you doing?

[regal scaffold]

If you don't add a newLine

It will all go to the side

And I saw it had a writer.newLine() method

[fluid river]

writer needs a special character to understand there is a new line

otherwise it doesn't know where to stop

[regal scaffold]

Fair

[young knoll]

Just stick it all on one line

[fluid river]

and it doesn't provide line writing

[young knoll]

New lines are a waste of bytes

[fluid river]

you can use a newLine() or

• "\n"

would probably work

also writer has subclasses

[regal scaffold]

It does

Which is nice too

[fluid river]

https://docs.oracle.com/en/java/javase/17/docs/api/java.base/java/io/PrintWriter.html

https://docs.oracle.com/en/java/javase/17/docs/api/java.base/java/io/FileWriter.html

in there you can use the same thing

[misty current]

so can anyone help me?

[tender shard]

set your jdk to 17

[misty current]

on the 1.19 module only?

would that compile

[tender shard]

are you using IJ?

you simply have to start maven through java 17

that's all

File -> Project Settings -> JDK

you can keep target/source level at 8

[misty current]

you mean project structure

i don't have project settings

[tardy delta]

yes

[tender shard]

erm yes

[misty current]

and that would still run on 1.8 servers wouldn't it

[tender shard]

yes

[misty current]

aight lemme try

[tender shard]

this lets you compile against java 17 dependencies, while keeping your actual .jar compatible with java 8

[misty current]

that worked, thanks

[tender shard]

np

[misty current]

also when building a multi module project, am I supposed to build the parent project?

[tender shard]

yes

but the parent doesn't have any .jar itself

usually you have a distribution module that shades in all your other modules

[earnest plinth]

[22:41:52 ERROR]: Could not load 'plugins/worldedit-bukkit-7.2.14.jar' in folder 'plugins'
org.bukkit.plugin.InvalidPluginException: java.lang.IllegalArgumentException: Plugin already initialized!

who can help me

[misty current]

yeah that's what i did, i have a plugin module that shades the core and the core shades all the nms implementations

[misty current]

#help-server

[tender shard]

You did „new MyMainClass()“ somewhere

Dont do that

[earnest plinth]

??

[tender shard]

Oh its worldedit

[earnest plinth]

yes lol

[tender shard]

Wrong channel

[tardy delta]

Yeah I got that, I'm asking if you got an idea what to do to fix xd

[eternal oxide]

if the array is empty there is no get(0)

[regal scaffold]

Are ACF tryhards online?

I want to make a command like:

    @Subcommand("text")
    @Description("Text a contact.")
    @CommandCompletion("@contacts")
    public void onTextCommand(Player sender, @Single String phoneNickname, String... message) {}

But currently the autocomplete goes for all parameters after phoneNickname which is actually the only one it should apply to, then I want to allow the user to be able to enter any amount of arguments since it's a message

@lost matrix Only acf tryhard I remember

[regal scaffold]

I just managed to StackOverflow my plugin... oh no

Infinite event loop gang

[tardy mist]

Please don't use @CommandCompletion on this method, so no autocomplete suggestions are shown after the first arg. Users will have to manually enter the full message

@Subcommand("text")
@Description("Text a contact.")
@CommandCompletion("@contacts")
public void onTextCommand(Player sender, @Single String phoneNickname, @VarArgs String... message) {}``` Here, I am using an `@VarArgs` on the method, to allow any number of args

And here, I am using an `StringBuilder` to concatenate all further args into the message:
```java
public void onTextCommand(Player sender, @Single String phoneNickname, String... messageParts) {
StringBuilder message = new StringBuilder(phoneNickname);
for (String part : messageParts) {
message.append(" ").append(part);
}
// Use message...
}``` 

Generally, to avoid autocomplete applying to all further `args`, you have two options:
1. Don't use `@CommandCompletion`
2. Use `@VarArgs` to allow an arbitrary count of args, and concatenate them yourself

[regal scaffold]

You are a G

Thanks for the insanely detailed answer

[tardy mist]

No problem, If have time, I will answer everywhere 😄

[regal scaffold]

❤️

I have another question unrelated then

[tardy mist]

Ask away

[regal scaffold]

I have a logger method that is supposed to write to 2 different files at the same time

For that I created 2 File instances, 2 BufferedWriter instances, 2 String builders

But I'm getting a very sexy StackOverflow error

It's so long I can't even read it

[tardy mist]

show the code please

[regal scaffold]

?paste

[undone axle]

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

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

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

If you want to look at a 1.1k staroverflow error

[tardy mist]

synchronize your access to the files, to avoid write conflicts

you can synchronize the whole method

[regal scaffold]

Wait but

Even if my files are completely separate?

[tardy mist]

or just use the File/BufferedWriter operations

[regal scaffold]

There is no chance both files would be the same

[tardy mist]

wait, let me rewrite it

[regal scaffold]

If you feel like it sure, otherwise just do a mockup

Thanks!

[tardy mist]

One thing I can tell you is, the synchronized keyword will ensure only a single thread can execute the method at a time

that will avoid conflicts

properly closing the resources ensures no leaks

checking for and handling IOException is always a good idea

[regal scaffold]

Wait but

What is the actual issue

Like I understand about synchronized

But if the method is just called once

Why does it matter

[tardy mist]

🤔

Hmm, then the error is because recursion

[regal scaffold]

That could be

[tardy mist]

your method is calling itself repeatedly

you have a recursive call to writeMessageLock() inside the method

you're accidentally creating and closing the File, BufferedWriter etc

[regal scaffold]

You saw the entire method tho

[tardy mist]

resources in a loop, causing repeated re-opening

[regal scaffold]

Let me log how many times it's called

Nope

Just once

I am big confusion

Slowly commenting 1 by 1 here we go

[tardy mist]

https://paste.md-5.net/iredafilih.java
https://paste.md-5.net/emiyexomup.java

[regal scaffold]

Will do your alternative if I can't find the reason why

[brave sparrow]

You don’t need to make that synchronized

It’s not being called from multiple threads

That’s unnecessary overhead

[tardy mist]

That is true.

Its just an example, but it was clarified

[regal scaffold]

Uhm ok

hold on

This is bad

So, commenting out line by line

And eventually reaching the bottom

Now... no stackoverflow

[brave sparrow]

Ya

Lol

[regal scaffold]

Without a single code change

How tf am I gonna recreate that so I can prevent

[tardy mist]

Simplify

[brave sparrow]

//me.tomisanhues2.rpphones.phone.abs.APhone.receiveText(APhone.java:314)

[regal scaffold]

Oh wait

[young knoll]

It’s very hard to cause a stack overflow with no code

:)

[regal scaffold]

I found something

[brave sparrow]

What’s on that line

[tardy mist]

He sent it

[regal scaffold]

Internal logic

?paste

[undone axle]

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

[regal scaffold]

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

Maybe it's not directly related with that

But another question

So in my logs, I'm openning and closing the files

Can't remove this file cause it says in use O.o

But it should've been closed

[tardy mist]

logic error, thats not valid

[regal scaffold]

That could be the error

I think it's time to implement a buffer to write stuff to files

Doing it on every log seems really inefficient

[tardy mist]

tbh, dssd is not a valid class or method name

wait i fix it for you

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

[regal scaffold]

I gtg rn so please tag me and I will see it. Thanks a lot

Wait what did you even change

The send message line

[quaint mantle]

hi, my default config file isn't being saved to my plugin folder

i have a config.yml file in the resources folder

[regal scaffold]

#saveDefaultConfig()

[quaint mantle]

and this.saveDefaultConfig(); was placed into the onEnable event

no errors are being thrown in the console

[tardy mist]

Objects.requireNonNull(Bukkit.getPlayer(this.phoneOwner)) should be Objects.requireNonNull(Bukkit.getPlayer(phoneOwner)).

no opening { before public void receiveText(Text text)
no closing } at the end of the method
color should be Color
event should be new ClickEvent()
append should .append()

this is what caught my eye at first glance

am i wrong, please correct, maybe i sleep with open eyes too

[desert spade]

On enable Event? Or the overriding method in your main class?

[quaint mantle]

the latter

[hazy parrot]

Why are you overriding it

[quaint mantle]

uhh

because that's what i saw when i opened my project

[hazy parrot]

?

[desert spade]

?

[hazy parrot]

You shouldnt override it lmao

[young knoll]

What?

[desert spade]

It's the method inherited from javaplugin

[quaint mantle]

when i first created the plugin it made this file automatically with an onEnable method and onDisable method

[hazy parrot]

OK?

[young knoll]

It’s normal to override onEnable

[hazy parrot]

saveDefaultConfig

Not onEnable

Or I misunderstand lol

[desert spade]

Is there already a different config file in your plugins folder @quaint mantle

[quaint mantle]

nope

[young knoll]

Actually there is a simple solution to this

?nocode

[undone axle]

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

[alpine swan]

sometimes I need to add spigot instead of spigot-api as a dependency in my maven for a plugin due to needing NMS. when I do this, I don’t get javadoc descriptions when doing ctrl q on a method. how can I fix this / add javadoc descriptions back since it’s not in spigot jar

[quaint mantle]

this is my first ever java project if code is spaghetti that is why

    public void onEnable() {
        MyDeathEventListener deathEventListener = new MyDeathEventListener(this);
        getServer().getPluginManager().registerEvents(deathEventListener, this);

        this.saveDefaultConfig();
        Logger logger = getLogger();
        File f = new File(getDataFolder() + "/");
        if(!f.exists())
            f.mkdir();
        File myFile = new File(f,"playerdata.yml");
        try {
            myFile.createNewFile();
            logger.info("Created playerdata file.");
        } catch (IOException e) {
            logger.severe("Failed to create playerdata file: " + e.getMessage());
        }
        getServer().getPluginManager().registerEvents(new MyJoinEventListener(this, myFile), this);
        logger.info("Exponential Bans is now started");
    }

[young knoll]

Does your jar have a config.yml file in it

And I’m the correct place

[quaint mantle]

i put it in the resources folder

startingTime: 4
increaseAmt: 4
maximumBanTime: 48

[young knoll]

Are you building with maven or gradle

[quaint mantle]

maven

[young knoll]

Alright

That all seems good

Hi guys, Im trying to make server like bhop or surf servers in cs, I mean passing maps and be able to vote for the next one. So the problem is that one map using command blocks can affect another map. So I think it's a good idea to just unload rest of maps (Server.unloadWorld) when map changing, but the problem is that for some reason bukkit won't allow to unload maps which have dimension = 0 (Overworld), I found out it from source code. Have you any ideas how to solve that?

[young knoll]

You can’t unload the main world

[quaint mantle]

well it can't be

[scarlet kelp]

it's not "main"

[quaint mantle]

because there's no config.yml file

[scarlet kelp]

it's just an overworld

and i have not only one world of this type

[young knoll]

Check the exported jar with something like 7zip

Make sure the config is in there in the right spot

[quaint mantle]

where should i be looking

[young knoll]

It should be in the same place as plugin.yml

[remote swallow]

it should be in the base jar

[quaint mantle]

nope

not there

oh wait

hello, does anyo0ne know of a way i could make it possible to place end crystals when there are light blocks in the way? i havent been able tot figure this out and i dont want to have to remov ethe light blovcks from my maps, cuz they dont look the best without light. please let me know if its possible

[quaint mantle]

i'm really silly

wrong file

yeah that was my mistake
