[tidal kettle]

dafuq is CraftItemStack

and NBTTagCompound

is this in 1.20.6?

[chrome beacon]

CraftItemStack is the implementation of ItemStack

NBTTagCompound is the nms class for NBT

And no it's not 1.20.6

Most likely something old like 1.8

[tidal kettle]

how can i get it in 1.20.4?

yes

[chrome beacon]

1.20.6 still isn't the default stable version

[tidal kettle]

i think i'm gonnai wait the stable 1.20.6 version and after do the display name thing

[golden ember]

how to fix this

[eternal night]

object is not an instance of declaring class

you are passing the wrong instance

[golden ember]

what bro 😄

[undone axle]

If you have a question, please just ask it. Don't look for staff or topic experts. Don't ask to ask or ask if people are awake or available. Just ask the question to the channel straight out, and wait patiently for a reply. Make sure you use the right channel regarding the topic of your question. Create a thread in case the channel is already in use!

[golden ember]

i dont know how to fix it

[vast ledge]

?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.

[vast ledge]

There

[eternal night]

ah

[eternal night]

I mean, share your code

[golden ember]

oh this is plugin code

[eternal night]

I mean, you are in #help-development

This is a channel for plugin developers having trouble

[golden ember]

https://github.com/haydenred/LevelTools

oh sorry bro...

[vast ledge]

Last commit was 1y ago

What version are you trying to use

[golden ember]

1.20

[eternal night]

plain 1.20?

[vast ledge]

1.20.?

The latest commit says added 1.20 support

[golden ember]

yes

[vast ledge]

Fun fact, that doesnt include 1.20.6, 1.20.5 or any of those

[golden ember]

maybe why my server its 1.20.4

[vast ledge]

1.20.4 isnt 1.20 thats why

[tawdry echo]

I want to create daily and weekly player kills tops and idk how do this, I mean reset at every day and week

[vast ledge]

Save starting time stamp in system nano

[river oracle]

Time usually

[river oracle]

Why nano

[vast ledge]

Why not

you could use millis aswell

[river oracle]

Use Unix time

[vast ledge]

true

@golden ember Is this your Plugin?

[vast ledge]

(LevelTools)

[tawdry echo]

Thats doesnt tell me much

[golden ember]

no

[vast ledge]

Save the timestamp in the unix time

[river oracle]

Well you need to save time

[vast ledge]

Do you know how to code?

[golden ember]

maybe yes i check

[vast ledge]

Where are you going to check if you can code?

[golden ember]

I don't know

[vast ledge]

Do you know Java, the programming language, that is commonly used, when developing with the spigot/bukkit api?

[golden ember]

no

[vast ledge]

Then you can hope that theres a newer version, this channel, is for users, that are having a problem, with there code, and want to fix it!

[golden ember]

okey bro chill

dont wory be hapy

[vast ledge]

?

[golden ember]

nah

didnt

[hollow vessel]

how can I change item's durability in 1.19.3?

[carmine mica]

not a good way. YOu just have to track it yourself pretty much in the PDC

[gaunt vapor]

https://www.spigotmc.org/resources/admibotintegration.116586/

Can anyone please test my plugin and tell me if it has any issues to you?

[fluid cypress]

i created a vault economy provider, bc i want to be able to add details to transactions. im checking the stack trace to get info about it, like what plugin did it, what command, etc. but, since im the author, i want to be able to extend it for my own plugins that also use the server economy, so i dont have to check the stack trace for my own plugins. so i need a way to communicate between two of my own plugins, but, without interfering with its economy provider ability, meaning, without modifying the withdraw or deposit methods with a details parameter or something

im not a java developer so i have no idea whats the proper way of doing that, i guess getting the plugin by name and then calling methods on it is not the best way, right?

[hollow vessel]

whta is pdc?

[chrome beacon]

?pdc

[undone axle]

https://www.spigotmc.org/threads/a-guide-to-1-14-persistentdataholder-api.371200/

[quaint mantle]

Insert own logger into provider

[fluid cypress]

umm thats what im doing, but i need the plugin that initiates the transaction to specify the details of it, not the provider itself

i mean, i wont modify quickshop, plotsquared, and all of those plugins, just to add details to when they use the economy provider, i will do some weird stuff with the stack trace and thats it. but, for my own plugins that use the economy, i would like to be able to optionally call some method in the provider to give more details or something

and im guessing there is a better way than this, but im not a java developer so i have no idea tbh

if (Bukkit.getPluginManager().getPlugin("MyProvider") != null) {
    Bukkit.getPluginManager().getPlugin("MyProvider").setupDetails("i will do something something")
    provider.withdraw(x)
}

idek if that would work tho

[quaint mantle]

There’s no way. Plug-ins should have their hook for custom economy

In vault you can’t really track which plugin doing the transaction

[fluid cypress]

well thats what im trying to solve, i already have a way of doing it by checking the call stack trace for all existing plugins, but i wanna do it the proper way with my own plugins

[charred blaze]

does the Bukkit.getEntity(uuid) load the chunk the entity is in?

[young knoll]

no

it has to be loaded

[patent coyote]

how can i check when the player does a command and the command failed or they didnt have perms

and not just for commands in my own plugin but when commands for other plugins also dont work

[vast ledge]

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

[hushed scaffold]

imo itd be better if the plugin self hosted the bot for its own instance ( so u just input the bot token in config ) , but thats just my opinion
having a centralized one could lead to some potential security issues, but 🤷

[gaunt vapor]

The whole purpose of the plugin is to make it easier for the user to integrate their Minecraft server to discord by just having an unique key like I did another project with just self hosting

Okay ty

[teal oracle]

how do i detect block right clicks?

is it the action event?

or maybe player interact event

[remote swallow]

player interact event

[teal oracle]

thanks

[inner mulch]

is there a way to make a nametag grayish dark, like when a player sneaks?

[teal oracle]

is this the correct way of doing it?

public void playerClick(PlayerInteractEvent e) {
        if (e.getMaterial() == Material.NETHER_STAR) {

        }

[inner mulch]

did you register it?

[teal oracle]

what does that mean

[inner mulch]

you need to register your listeners

for them to be called

[teal oracle]

oh yes i did

[inner mulch]

okay

[patent coyote]

how would i use this to check if the command sender was able to successfully send the command or not?

[royal heath]

Should I dependency inject my plugin instance or make it a singleton? I ask because I have a singleton storage class that stores references to objects needed throughout the program, and its messy to dependency inject into a singleton

I ask because I've been using it as a singleton and tons of people on the forums say to inject it

[young knoll]

Neither is necessarily “more correct” but you will find some people that are die hards against having it as a singleton

[royal heath]

Ah okay. I just find it makes the code more messy, especially if you're dealing with another singleton already

I could inject my storage class, but I'd like to prevent the ability to make a new instance of the storage class

[worthy yarrow]

I will use di considering there’s more than one call the to the main, otherwise I just get it statically

The reason for people arguing against your main being a singleton is because iirc bukkit offers a static method of getting your main instance

Bukkit#getPlugin(plugin.class) ith if my brain is braining right now

[royal heath]

Right, but I remember having issues with that in the past. I can't exactly remember why as it was well over 4 years ago but I haven't ran into it since because I have been using singleton method since

[worthy yarrow]

It kinda depends on your impl as well, I personally only put startup functions in the main

[royal heath]

I haven't touched spigot as well since about 2021 so I'm still a little rusty on it

[worthy yarrow]

If I had to guess those issues came from premature initialization of some class before the main was actually loaded

[royal heath]

That makes sense. I'll see about using getPlugin, however getInstance looks a lot cleaner than the big Bukkit#getPluginManager(plugin.class) way

[young knoll]

Yeah iirc that also might involve some stacktrace jank

Not sure I’ve not looked at the impl

[royal heath]

How would you recommend getting instances of a Bots storage class?

In my plugin I instantiate bots from the config yml, and then store it in a class to manage them. I use it as a singleton. I could dependency inject, but it allows people to make new instances of the bots class

[worthy yarrow]

The only reason I use Bukkit.getPlugin is to define a constant of the main for whatever class I need it in otherwise di imo is just simpler

[royal heath]

I would like to use DI, and I could use it if I also DI the bots class, but I'm not sure if I want to use the bots storage class as a singleton or not

[worthy yarrow]

I’d need more context to give an opinion on that tbf

Is bots a rather globally used class?

[royal heath]

Well, it's used in main, an event handler, and a command handler to close and open the pools, as well as reload them. This kinda points me towards utilizing dependency injection, however I'd like to avoid making new instances of the Bots class for obvious reasons

I know I could still use bots as a singleton but in implementation it is gross because I'd need to lazy initialize it and pass in the plugin class into the getInstance

[worthy yarrow]

It is possible to only ever have a single instance of said class with di, however the structure has to be solid and initialization has to be precise

[worthy yarrow]

This leads me to say just play with di a bit, that just sounds like a mess waiting to happen considering you change the structure in any way

[royal heath]

Yeah I agree. I guess its not the end of the world if its possible to make a new Bots() class anyways.

[worthy yarrow]

Coming from my Java bible “no impl should be considered “good” until it’s been rewritten a couple times”

That’s just to say in the experimentation, you’ll start to find / see different and possibly better approaches

[royal heath]

I like that "proverb"

[worthy yarrow]

You want the actual quote?

[royal heath]

Lol sure

[slender elbow]

di and singleton aren't mutually exclusive patterns

but people too often mix and confuse singleton with statically accessible

[worthy yarrow]

Eh I can’t find it, but that was the gist of it

[worthy yarrow]

That was the point of the argument earlier, there’s already a provided method of getting your main class so a lot like to argue against the use of a singleton main

[slender elbow]

that's not what I'm saying

I'm saying singleton and di can be used together perfectly fine

without any kind of static getter

[worthy yarrow]

Sure, but in relation to your main being a singleton

[slender elbow]

your plugin is already a singleton, and that's nothing to do with the getter spigot offers you

[royal heath]

I get the difference to an extent. I usually use it to cache certain data such as, in my case, bots loaded in from a config, and that will only be used once

Which from my interpretation was the use of a singleton

[worthy yarrow]

Extends javaPlugin induces the fact it’s a singleton correct?

[young knoll]

21 is the version the game uses and is also LTS

So it’s best to stick with

[broken nacelle]

dont forget the @EventHandler annotation

[royal heath]

I think it just induces the fact that its abstract no?

[slender elbow]

I mean the fact that there is a single instance makes it a singleton

and that instance is created by the server

[worthy yarrow]

Idek I ish I had a spigot api book 😦

[slender elbow]

the server injects stuff like the respective Server instance

[worthy yarrow]

Ah yeas sorry I’m being cooked

I’ve had 3 flights today man I’m tired

[worthy yarrow]

Yes you are correct, like I said I’m just being cooked… without actually being cooked

[royal heath]

Ha no worries I feel ya. I fly for work across the country and it wears you down

[worthy yarrow]

Well when it’s a triple connecting flight to get to your destination… that shit sucks lol

[royal heath]

Lol yep, thats almost always the case for me

sitting in airport for 2 hrs

[slender elbow]

wth

[royal heath]

huh?

[worthy yarrow]

Travel jobs man, my father used to make about 250k miles a year and that’s not even like bad

[slender elbow]

that's crazy

mentally draining

[royal heath]

It's usually just for meetings. It sucks lol bc it could be an email, but its also cool because you get to leave where you live for a bit to a lot nicer place

Usually for team building

[worthy yarrow]

Yeah you definitely get the benefit of traveling… but there is quite a cost to doing so as often as most people in that position do

[royal heath]

I also have to front it which sucks

and expense it

[worthy yarrow]

Eeeeeeeeek really?

[royal heath]

Yeah lol, credit card helps for that though

[worthy yarrow]

At least they reimburse ya but still for mandatory meetings as most of them are, company should be taking those expenses

[royal heath]

I agree lol.

Atleast I get free credit card rewards

Don't gotta spend a penny

[worthy yarrow]

It was odd, for my fathers work they had him pay for local trips, but paid for international ones

[worthy yarrow]

Free credit building as well

(Hopefully)

[royal heath]

Yes lol

[royal heath]

Would they reimburse him??

[worthy yarrow]

Ofc

Just odd how they finance the international trips and not domestic

[patent coyote]

.

[eternal oxide]

You can't. The best you can do is check if the command is valid and they have permissions to use it.

[royal heath]

ahh lol i was gonna say

[patent coyote]

how do i check if its valid?

[north jetty]

there lib for detect hold right click?

[eternal oxide]

You check it exists. Thats bout it

[patent coyote]

how do do that

[worthy yarrow]

If (sender != null)

[eternal oxide]

I have a feeling we are in an xy situation here

[patent coyote]

?

[worthy yarrow]

Probably

?xy

[undone axle]

https://xyproblem.info/

[eternal oxide]

Why do you want to know if a command ran?

[patent coyote]

I want to log every command ran

but i dont wanna keep track of commands that dont exist

[worthy yarrow]

Well you can’t keep track of something that doesn’t exist so

[patent coyote]

0-0

[worthy yarrow]

If it does exist then log the usage otherwise there’s no issue

[patent coyote]

im confused?

if i do a command like /afauijfbaoijbf obiosly noty a command

it still gets logged

[worthy yarrow]

Right

Mmm we prolly need some code then

[eternal oxide]

pass the command (no args) in here and see if you get a command back or null.

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/Bukkit.html#getPluginCommand(java.lang.String)

[patent coyote]

@EventHandler
    public void onPlayerCommand(@Nonnull PlayerCommandPreprocessEvent event) {
        String playerName = event.getPlayer().getName();
        String command = event.getMessage();
        String timestamp = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date());
        sendEmbeddedMessage(playerName, command, timestamp);
    }```

im logging the commands in a discord server

using a discord bot thats included in the plugin

lol isnt a command

[eternal oxide]

getMessage, split the command then if (Bukkit.getPluginCommand(command) != null) logMessage

[worthy yarrow]

Elgarl just faster than I

[patent coyote]

ok why does the /msg not work?

[eternal oxide]

msg is a base command, not a plugin

[patent coyote]

ah right

how do i tack it for base commands aswell

wait

can i get what plaugin the command is from

cuz thats would be pretty cool

[eternal oxide]

it should be in the returnd command

[patent coyote]

?

[eternal oxide]

the returned PluginCommand https://hub.spigotmc.org/javadocs/spigot/org/bukkit/command/PluginCommand.html

has a getPlugin() method

[patent coyote]

ok but hoe do i also check if the command is from minecraft instead of jus plugin commands

omg

my spelling

0-0

[eternal oxide]

Not ideal but you could use https://hub.spigotmc.org/javadocs/spigot/org/bukkit/Bukkit.html#getCommandAliases() and see if the command is a bukkit command

not as simple to process though

[patent coyote]

seriously no method to just get minecraft commands?

intresting

[young knoll]

You could make a list of them

Obviously not ideal tho

[patent coyote]

hmm

[ember dew]

How do people typically develop recipes that allow the items to be swapped out for others(in 1.8), for example, if a recipe has a diamond, coal, and iron, allow the coal to be swapped out for a second iron

I understand it's not possible through a recipe, but how would you get around this using a crafting table

[royal heath]

Can't you just make two recipes

[ember dew]

The problem is, I don't have to have hundreds of recipes for larger combos

[royal heath]

What if you make a wrapper for the recipes

well, I guess it still runs into the same issue

Actually make a class that internally has shapedrecipe, then maybe pass in an array of recipe shapes?

[ember dew]

That was what I tried first

I just don't think using the vanilla recipe manager would be worth the effort

But I'm clueless on where to go to next

[royal heath]

for example, you could do

recipes = new MultipleRecipe([['I','C','I'], ['I','I','I']], item));
recipes.addRecipes();

or something along those lines

[ember dew]

But this would still be adding a lot of recipes, in theory

[royal heath]

Yeah, however you wouldn't have to write out the create recipe logic more than once

[ember dew]

Well yeah

There's a collections library that does something like this

I tried checking for click events, checking for items in the crafting matrix, and setting the the output, but it causes an invisible output and didn't set the output until the player interacted with the inventory once more

[young knoll]

Have you tried using updateInventory

[ember dew]

That causes a visible flash

Hypixel does this exact thing, perfectly

[royal heath]

Ah yeah. You honestly could do it this way too it will be a little messier though:

recipes = new MultipleRecipe(['I/C','I/D/G','I/C'], item));
recipes.addRecipes();

You'd have to map each character to a material though

[ember dew]

And I doubt they're creating hundreds of recipes

[ember dew]

If I don't find an efficient alternative, I'll have to

[royal heath]

It would be easier for mkaing recipe where maybe you could use a wood plank instead of a log

[ember dew]

Currently, I'm doing 5 items

[royal heath]

recipes = new MultipleRecipe(['I','P/L','I'], item));
recipes.addRecipes();

so like Iron, Plank/Log, Iron

[ember dew]

So it's messy

[ember dew]

Is MultipleRecipes a class?

[royal heath]

Ah yeah. I'm not too sure then, this is the only way I could think of.

No, I meant make it yourself

you'd just iterate through the array

[ember dew]

Thought I overlooked something

[royal heath]

Ah no haha

[ember dew]

Got excited

[royal heath]

Lmaoo, didn't mean to get your hopes up

[ember dew]

I hate working on 1.8

[royal heath]

wait does this work on >1.8?

[ember dew]

I'm pretty sure there's a class for something like this

or method

Idk

[young knoll]

Where does hypixel have a ton of recipes with swappable items

[ember dew]

I'd have to check to be certain, I just remember one rn

I'm referring to UHC in specific

[young knoll]

Hmm

It’s been so long I don’t remember anything about uhc

[royal heath]

My way with the slashes is probably the better way at it, however you could run into issues where you want it to be coal iron coal, diamond diamond coal or diamond diamond diamond but not coal diamond diamond

[ember dew]

mhm

Also, modern versions have the RecipeChoice class

🙏

[royal heath]

lol wtf

[ember dew]

Huh?

[royal heath]

nvm thats the interface

[ember dew]

Oh

[royal heath]

I think ExactChoice is just for using itemstacks in your inventory

It's an interesting idea, maybe tomorrow I might see if I can rip something up and make a library or something

However, might I ask why you are using 1.8?

[ember dew]

For a friend

I love 1.8, just not for development

[buoyant viper]

https://tenor.com/bl2al.gif

https://tenor.com/4TCy.gif

sorry had to do a two parter bc none of the gifs have the full interaction

[royal heath]

hahaha

[ember dew]

lmfao

[royal heath]

I might see if I can rip something up and make it cross version platform. It seems like a good problem to solve

[ember dew]

I wonder if there's downsides of implementing a few thousand recipes

[royal heath]

MC has more than 1000 recipes if I recall

Yeah online all they say is to use multiple recipes

[hybrid seal]

So need some help here. First time plugin developing, I figured out how to set up the package structure, but not the code. I'm set up in plugin.yml to call main: com.gmail.nikitis.maximumbuildheight.maximumbuildheight

However, I have no code in the trailing maximumbuildheight class, but it's in my BlockPlaceListener class, but if I call that in plugin.yml main: It complains that I don't have "extends JavaPlugin" in the class line for BlockPlaceListener. How do I fix this? Code below:

import org.bukkit.plugin.java.JavaPlugin;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.block.BlockPlaceEvent;
public final class maximumbuildheight extends JavaPlugin {

}

public class BlockPlaceListener implements Listener {

    @EventHandler
    public void onBlockPlace(BlockPlaceEvent event) {
        double maxY = 256.0; // Set your desired Y-coordinate threshold here

        if (event.getBlock().getLocation().getY() > maxY) {
            event.setCancelled(true);
            // Optionally, you can send a message to the player:
            event.getPlayer().sendMessage("You cannot place blocks above Y " + maxY);
        }
    }
}```

[ember dew]

Make a new class for the listener

Or make a method for the listener in the main class, and run it from onEnable

[hybrid seal]

I'd rather keep it as clean as possible, how would I do the latter?

[ember dew]

Keeping it clean would be keeping everything in one file?

[hybrid seal]

I want the plugin to load and always be on.

[ember dew]

Make a method inside of your main class for the event handler

Then simply run that method on plugin start

Which would be inside of the onEable method, which you don't currently have

[hybrid seal]

So like? ```package com.gmail.nikitis.maximumbuildheight;
import org.bukkit.plugin.java.JavaPlugin;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.block.BlockPlaceEvent;
public final class maximumbuildheight extends JavaPlugin {

public class BlockPlaceListener implements Listener {

  @EventHandler
  public void onBlockPlace(BlockPlaceEvent event) {
      double maxY = 256.0; // Set your desired Y-coordinate threshold here

      if (event.getBlock().getLocation().getY() > maxY) {
          event.setCancelled(true);
          // Optionally, you can send a message to the player:
          event.getPlayer().sendMessage("You cannot place blocks above Y " + maxY);
      }
  }

}
}```

[reef turret]

since spigot 1.20.6 is compiled on java 16, is there a way of keeping a plugin backwards compatible to java 8 or should I just make to different versions; one for 1.20.6> and one for 1.20.6<

[ember dew]

Remove the inner class

PlacePlaceListener

[hybrid seal]

Could you format it for me?

I really have no clue

i've never seen a working example

[ember dew]

I'd recommended reading documentation, or watching a video tutorial on plugin creation

[hybrid seal]

i have

so many

they are all different

i need an expert here

[sullen marlin]

The only way you will ever get compatibility is by compiling against the earliest version you want to support

[ember dew]

I'd recommended getting the Minecraft Development extension, if you're using IntilliJ

It just makes starting your plugin easier

[hybrid seal]

just using eclipse and maven

Linux

I get the compiling part of it, and the .jar structure

I don't understand how the code is called. or the classes are called

[ember dew]

public final class PluginName extends JavaPlugin {

    @Override
    public void onEnable() {
        
    }

    @Override
    public void onDisable() {

    }

[reef turret]

the server sends you to a game instance which runs on limited resources

[glad prawn]

onReload when

[ember dew]

oop

[sullen marlin]

It's called by the onEnable method and then you calling registerListeners

[hybrid seal]

So paste my blockplaceevent code in the onEnable section?

[ember dew]

The event should be outside of onEnable

You then call the event from onEnable

[sullen marlin]

No your code is fine you just need to register it as a listener in onEnable

[ember dew]

oh wait, it is

Not how I personally do it

[hybrid seal]

So like?

import org.bukkit.plugin.java.JavaPlugin;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.block.BlockPlaceEvent;
public final class maximumbuildheight extends JavaPlugin {

  @Override
      public void onEnable() {
        public class BlockPlaceListener implements Listener {

        @EventHandler
        public void onBlockPlace(BlockPlaceEvent event) {
            double maxY = 256.0; // Set your desired Y-coordinate threshold here

            if (event.getBlock().getLocation().getY() > maxY) {
                event.setCancelled(true);
                // Optionally, you can send a message to the player:
                event.getPlayer().sendMessage("You cannot place blocks above Y " + maxY);
            }
          }
        }
      }

      @Override
      public void onDisable() {

      }
 
}```

[hybrid seal]

I really just want the max-build-height value for server.properties to be honored again with spigot.

[glad prawn]

it's possible but yeah no one writes like that

[hybrid seal]

i have a map that I can't allow building over height 256.

and when minecraft allowed 320 Y height, it seems to have broken max-build-height variable.

Can this be fixed in spigot?

I was attempting to learn to make a simple plugin to just cancel the block place event if Y is over 256, but apparently it's too complex for me

I feel the code is solid, but I don't know how to arrange it in classes and methods

[ember dew]

You don't have to register your main class for listners, right?

[hybrid seal]

Hell if I know

[ember dew]

I don't remember but

public final class Temp extends JavaPlugin implements Listener {


 @Override
    public void onEnable() {
        getServer().getPluginManager().registerEvents(this, this);
    }

    @EventHandler
    public void onBlockPlace(BlockPlaceEvent event) {
        double maxY = 256.0; // Set your desired Y-coordinate threshold here

        if (event.getBlock().getLocation().getY() > maxY) {
            event.setCancelled(true);
            // Optionally, you can send a message to the player:
            event.getPlayer().sendMessage("You cannot place blocks above Y " + maxY);
        }

    }

    @Override
    public void onDisable() {

    }

}

[hybrid seal]

if that can work i'll take it

[ember dew]

I don't personally put event handlers in my main

[quaint mantle]

might want to add

 @Override
    public void onEnable() {
        getServer().getPluginManager().registerEvents(this, this);
    }```

[ember dew]

OH

Yeah

[hybrid seal]

Do i wanna change class Temp to class BlockPlaceListener?

[ember dew]

Yeah

My bad

Or whatever your main class name is

Which appeared to be
maximumbuildheight

[glad prawn]

your plugin name rly is BlockPlaceListener, dam-

[ember dew]

Innovation

[hybrid seal]

maximumbuildheight

[ember dew]

You can remove onDisable since you have no use for it

Since you wanted it "clean"

[hybrid seal]

oh snap it works!

[ember dew]

Congrats

You're now a plugin developer

[glad prawn]

[reef turret]

!!!!

[hybrid seal]

Sweet! And thanks for the example. I can learn and play around with that

next i'll work on adding perms for bypass.

but I think I can learn that from the tutorials

[ember dew]

Perms are really easy

Just add an if statement to the top of the event handler

if(event.getPlayer().hasPermission("maximumbuildheight.bypass")) return;

[hybrid seal]

Cool

I'll play around with it

[ember dew]

But seriously, if you don't already know some java, I'd spend a few days learning

[hybrid seal]

Yeah, I learned it like back in Java 6 days, Forever ago. I haven't used it in probably 18 years

A lot has changed

[ember dew]

Oh shit

Well, welcome back!

[spice burrow]

is this correct for Player#spawnParticle()?
e.getPlayer().spawnParticle(Particle.EXPLOSION, eventLocation.getX(), eventLocation.getY(), eventLocation.getZ(), 2)

[hybrid seal]

Like my code worked first time. I just didn't know how to structure it

never dealt with groupid's archetypes, etc

The IDE is new to me

and I didn't know what minecraft required for jars

like package structuring

[ember dew]

event.getPlayer().spawnParticle(Particle.BLOCK_CRACK, event.getPlayer.getLocation(), 1);

[spice burrow]

yea im a webdev but recently started learning java & spigot, im used to vscode

[hybrid seal]

I used to code web pages back in the netscape days using only notepad

Stopped about when dreamweaver came out

[spice burrow]

oh ty, i couldn't find a location arg in the docs prob just an oversight. when i was spawning it manually with x,y,z it wasn't showing but ill give that a shot

[ember dew]

Well, you can specify x y z, it's just simpler if you just get the players location

[spice burrow]

im stupid

i called it after i cancelled the event 😂

[ember dew]

Actually, idk why that didn't work

[hybrid seal]

Well I won't tie up the dev channel with chitchat, Thanks again! I'll likely be back as I practice adding commands, and perms.

[ember dew]

Yeah, you kind of get used to minor oversights that cause you to troubleshoot for an hour 😭

[spice burrow]

you and i both ha, everyones been super helpful and patient for me though

[spice burrow]

happened to me when i was making some custom enchants yesterday

i had a spelling error that wasn't showing in intellij for some reason and i spent 3 hours trying to find out what was going on

[wraith delta]

Q: I see several resources for playing specific sounds, but they are all out of date. How would you play a enum sound like cave18 in 1.20?

[eternal oxide]

playing sounds has not changed

[wraith delta]

The packet for playing specific sounds is out of date. is there a list of them somewhere

PacketPlayOutNamedSoundEffect no longer seems to work in 1.20

[eternal oxide]

use teh API not packets

No point in packets for sound. Thats literally all the API does

Player#playSound and World#playSound

[wraith delta]

you have to, to play specific sounds cave18

[eternal oxide]

I very much doubt thats the case https://hub.spigotmc.org/javadocs/spigot/org/bukkit/Sound.html

[wraith delta]

Where do you see cave18 there

[eternal oxide]

you will not find the MC naming there

[wraith delta]

the sound comes from the resource pack. the api only has AMBIENT_CAVE which plays cave 1-19 at random. if you use packets you can play a specific cave

[eternal oxide]

You can play any resource pack sound using its defined name

literally the name of the ogg files in your resource pack

[wraith delta]

I tried "ambient.cave.cave18" does not work, the resource pack is the default minecraft not custom, doesnt seem to be located in the resourcepacks folder

[eternal oxide]

you shoudl not need the path

[wraith delta]

What would i need

If you dont mind showing such example would be awesome. im not sure where that sound comes from besides random from AMBIENT_CAVE

[eternal oxide]

No clue I've not done anything with resource packs

um which sound?

[wraith delta]

cave18

ambient_cave plays cave# at random choice from 1-19. I want to play cave18

[eternal oxide]

IDE slow to open this morning

[wraith delta]

No worries. I’ve been researching for a while and everything is about 1.8 for playing sounds, which is a bit outdated

[eternal oxide]

seems I've not built remapped for 1.20.6 yet

[wraith delta]

I’m using 1.20.2

But it may be similar in 1.20.6 idk

[chrome beacon]

yeah you really don't need nms

[eternal oxide]

yeah no, that is just a requirement of my test plugin so I can use anything 😉

I don;t see any way to access individual ambient sounds though

Registry only gives the predefined enum values

[chrome beacon]

You can give play sound a string

Which should work the same way as the play sound command

iirc

[wraith delta]

I saw on spigot on forums someone posted how to play it with packets, that’s all I know. But it was 1.9

[wraith delta]

Could you try to play cave18?

[chrome beacon]

Would probably be faster for you to try it

[wraith delta]

I’ve tested “cave.ambient.cave18” not working

[eternal oxide]

one sec

[wraith delta]

I don’t know if it’s the right directory, but it seems right

Unless I forgot to add the category or something. Maybe one of you are smarter with this and find a way

[eternal oxide]

I will in a few, but I seem to have broken my tesst plugin 😛

[wraith delta]

Ah np. Take your time. If it’s a bit then ping reply me lol

[eternal oxide]

Um, this one has me stumped

that makes no sense at all

[ivory sleet]

why not

[eternal oxide]

I can not use player as a variable

am I just not awake

it says player is undefined in the player. bit

[ivory sleet]

ugh yea, maybe the static analyzer is a bit goofy, did u try to just call a method on the player, like typing it all out

[eternal oxide]

yep it's not accepting it

[spice burrow]

is it preferred to use the string version of player's uuids in my db, or is it okay for them to be stored like this
Binary.createFromBase64('C0+TsPGfbl9ttGqWfULLiQ==', 3)

[ivory sleet]

hmm and you got the right java version?

[wraith delta]

You could use “sender”

It’s the same thing

[eternal oxide]

yep, one I used fo ra logn time 16 with 1.19.4

[ivory sleet]

sender is of type CommandSender tho

[wraith delta]

You could convert sender to player

[eternal oxide]

This is strange as it works as a variable to pass/use IN a method call

[ivory sleet]

that’s what elgar is doing

with negated pattern matching

[wraith delta]

Player player = (Player) commandSender;

[eternal oxide]

This works fine

[wraith delta]

Why do you need a item display for sound?

[eternal oxide]

ok now it magically fixed itself

No, this is an old test plugin I was just modifying to test sounds

panic avoided, the magical pixies of IDEs fixed itself

[valid burrow]

id say your compiler is goofy

[eternal oxide]

yeah I restarted it and cleared caches but it just magically started working

[valid burrow]

mhm

[eternal oxide]

um, perhaps not

[valid burrow]

intellij had a lot if these recently

no clue what they did to it

[eternal oxide]

super wierd its not fixed, but it does not see it as a variable

[pseudo hazel]

the funny part is it seems to work when passing it into a function xD

[eternal oxide]

yeah, I can use it AS a variable in a method call, but can;t use it as a local variable

[pseudo hazel]

what if you use proper {} around the if

might be a weird parsing thing

[eternal oxide]

it would not be available outside the scope I bet

works in the scope of {}

[pseudo hazel]

but how, it should be the inverse

[eternal oxide]

if I change to if (sender instanceof Player player) { it works in scope

[pseudo hazel]

right

[eternal oxide]

but early exit its not seen as a local variable UNLESS being passeed as an arg

methodCall(player.xxx works fine, but player.xxx does not.

wierdest issue I've ever seen

[ivory sleet]

Maybe eclipse is just a bit goofy like that

Messing with you

[valid burrow]

did you set your language level in eclipse?

[eternal oxide]

um good point I believe I changed it to 21 recently when testing

nope, this is set to 16

ah well a problem for future me

[wraith delta]

17 is good

[eternal oxide]

This IDE is out of dsate so I guess it could be a bug

[ivory sleet]

does this mean you finally gonna try out intellij?

[eternal oxide]

lol no, I have other installs of Eclipse 🙂

[ivory sleet]

😭

[molten hearth]

most enjoyable eclipse experience

[eternal oxide]

I did "try" Ij once. Did not like it

[ivory sleet]

really?

i believe there is even an eclipse theme for intellij

in case u wna make it look like eclipse

[eternal oxide]

I like to have multiple projects open in one view

[ivory sleet]

ah, right, intellij cant do that

[wraith delta]

eclipse is great, feels more lightweight

[eternal oxide]

um this is worrying. I just opened my MC 1.19.4 and it has a wierd server I've never accessed

[chrome beacon]

So I did a bit of research on the sound effect

Looks like you can't play a specific variation without a resourcepack

[charred blaze]

?bootstrap

[undone axle]

Bootstrap Jar
The main spigot-1.18.jar is now a bootstrap jar which contains all libraries. You cannot directly depend on this jar. You should depend on Spigot/Spigot-API/target/spigot-api-1.18-R0.1-SNAPSHOT-shaded.jar, or the entire contents of the bundler directory from your server, or use a dependency manager such as Maven or Gradle to handle this automatically.

Please read the release notes for further information: https://www.spigotmc.org/threads/9-years-of-spigotmc-spigot-bungeecord-1-18-1-18-1-release.534760/#post-4305163

[wraith delta]

i hear that for 1.8 but for 1.9 no

with packets

[chrome beacon]

I don't think that's the case

also the audio id you have is wrong

At least for 1.20.4 which I was testing on

[wraith delta]

whats the id?

maybe protocollib could - last resort

[eternal oxide]

oh I broke playSound 😛

[spice burrow]

Anyone know whatever work around hypixel uses on their scoreboards to prevent the score #s from displaying?
mine vs their comparison below

[dry hazel]

it can (on macos)

[eternal oxide]

player.playSound(player, args[0], 1, 1); passing "AMBIENT_SOUND"

I guess you have to pass an invalid/valid MC sound name

Caused by: net.minecraft.ResourceKeyInvalidException: Non [a-z0-9/._-] character in path of location: minecraft:AMBIENT_CAVE

[chrome beacon]

minecraft:ambient.cave

same as the /playsound command

which I mentioned earlier

[eternal oxide]

yep I'm just not reading

[wraith delta]

looks like ima have to use protocollib. https://pokechu22.github.io/Burger/1.20.4.html#sounds:ambient.cave

they have cave18

[chrome beacon]

No

[wraith delta]

?

[chrome beacon]

That only shows one key

which is ambient.cave

You cannot target the specific cave sound

[wraith delta]

Its not here? https://www.wiki.vg/Protocol#Entity_Sound_Effect

[eternal oxide]

no

[chrome beacon]

I already told you

it's not possible

without a resourcepack

[eternal oxide]

https://pokechu22.github.io/Burger/1.20.4.html#sounds:ambient.cave

notice they are all under Id 7

no individual id

[wraith delta]

it worked, by using a string " " with 1.8 jar 😭

i need 1.20

[eternal oxide]

not possible

[wraith delta]

i had to test cuz i keep seeing more forums with the answer

works fine but not in 1.20

because it is a resource pack

can try and see what protocollib reads

[eternal oxide]

wiki.vg

you can not go outside the protocol

the only variation in the protocol for playing sounds is using an id of zero. then you can pass a name

for resource pack sounds

[smoky anchor]

number format
Should be in the API too iirc

only 1.20.3 and up

[quaint mantle]

It might be some client hiding the numbers.

[spice burrow]

ah ty, im in 1.20.4 which makes sense

[wraith delta]

Is it possible to add the resource pack sounds without the user having to download a pack on join?

[eternal oxide]

no

um sec, seems its possible

[wraith delta]

if its gonna popup, id rather go without. kind of annoying to have those downloads.

[eternal oxide]

oh my playing a sound from a set is possible btu it's VERY difficult. It requires working out what random seed is needed to play each

so you would still use teh ambient.cave but you specify the seed

[wraith delta]

silly stuff. its weird they wouldnt allow simply adding cave.ambient.#

[wraith delta]

if its universal could find the seed online maybe?

unless you mean a seed that has that location where you are running the code

[eternal oxide]

no, it's literally a weighted seed

sounds are loaded on the client from sounds.json

[valid burrow]

only works in newest versions

[eternal oxide]

the client pulls a random using the seed you pass

if you pass the same seed everytime you should get teh same sound of the set

[wraith delta]

clients are running vanilla pack which should have the sound

[eternal oxide]

you have to work out what seed will play the specific sound you want

[wraith delta]

how to input that variable in the playSound seems trouble to fit tho aye

[wraith delta]

just cave 18 lol

[spice burrow]

yea shouldn't be an issue, ill just add support for older clients with the numbers there

[valid burrow]

mhm

[eternal oxide]

you have to use packets, this is not supported in the API

[wraith delta]

that was my original question. how to play sounds in 1.20 through packets because everything online is for 1.8 lol

its ok tho can probably mix some other sounds to make similar

[eternal oxide]

ClientboundSoundPacket

[acoustic pendant]

Hey, so i have a command manager class that uses an arraylist to register commands: ```cs
public CommandManager(NexusCore plugin) {
this.plugin = plugin;
//add subcommand
subCommands.add(new CreateCommand());
subCommands.add(new DeleteCommand());
subCommands.add(new SpawnCommand());
subCommands.add(new NexoCommand());

```cs
 else if (args.length > 0) {
                for (int i = 0; i < getSubCommands().size(); i++) {
                    if (args[0].equalsIgnoreCase(getSubCommands().get(i).getName())) {
                        getSubCommands().get(i).perform(player, args, plugin);
                    }
                }```

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

but for some reason SpawnCommand and NexoCommand

when i use them, it says that they are out of bounds

[rapid vigil]

You are using an argument that doesn't exist

[acoustic pendant]

No, if i do that it just doesn't do anything

because of the if

[rapid vigil]

send these classes

[acoustic pendant]

if I use an argument that do exist is when i get that error (only with spawn and nexo )

okay

[acoustic pendant]

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

[eternal oxide]

new ClientboundSoundPacket(?, SoundSource.AMBIENT, volume, pitch, seed, x, y, z);No idea what the ? arg is though

[smoky anchor]

size() - 1 I think
'cause for 7 elements you will have size of 7 but indices of 0-6

[eternal oxide]

just says Holder<SoundEvent>

[acoustic pendant]

I'm starting the loop in 0 because of that

and that would be the problem if only the last added wasn't working

[smoky anchor]

oh ye, ignore what I said

[acoustic pendant]

np xd

[rapid vigil]

what is in line 44?

in your NexoCommand class

[acoustic pendant]

nothing xd

ooh wait

could be args[1]?

don't think so

yesterday was working actually

[eternal oxide]

in 1.19.4 probablyjava SoundEvent event = SoundEvent.createVariableRangeEvent(ResourceLocation.tryParse("minecraft:ambient.cave")); packet = new ClientboundSoundPacket(event , SoundSource.AMBIENT, volume, pitch, seed, x, y, z);

[rapid vigil]

try adding

if(args.length < 2) {
    return;
}
``` below the permission check

[acoustic pendant]

oh

that makes a lot of sense

i'm doing the args check after that

[rapid vigil]

yeah you're getting the argument without checking if it exists

[acoustic pendant]

thanks!

yea yea

just realized

[rapid vigil]

which is what I said from the very beginning ^^

[glad prawn]

ill create something like maxArgs to check before doing anything to prevent missing args

[acoustic pendant]

yea, but thought it was the first argument

my bad sorry

[scarlet gate]

How would I go about handling the items in regards to calling a BlockDropItemEvent?

I currently spawn the item entities and then pass a list of those entities into the event but I don't think this it is respecting the modifying of the list

[sullen marlin]

why are you calling the event?

[sullen marlin]

shouldn't need packets for sounds :\

[eternal oxide]

Its to play a specific ambient from a set

not a randome one

Need to be able to define teh random Long

[wraith delta]

to play cave18

[eternal oxide]

I'm about to test some code

[short drift]

Since permissions can be registered from code as an alternative to registering them from plugin.yml - can the same be done with commands or is it mandatory to define the commands in plugin.yml?

[dapper flower]

btw my account can't be verified and #verification gives me errors when i open the channel, what can i do?

[glad prawn]

Verified 🤔

[dapper flower]

it is fighting back tho, LOL

I see the rank coming and getting removed and the name changing too

no idea what happened

[glad prawn]

at least ur verified lol

[dapper flower]

why can't i send images tho

couldn't verified people send images?

[glad prawn]

bruh

[molten hearth]

LMAO

why do i keep seeing it verify and unverify you AHAHA

[glad prawn]

yes lol

[dapper flower]

MAN I AM TELLING YOU

I BECAME A BLUE LIGHTBULB

[molten hearth]

you gotta make sure you upload images in the available time frame

[dapper flower]

why does this stuff happen to me

even if i unbind the account (idk if can do that even) i still can' load the verify channel

oh i can do it everywhere wait lemme test it out

[glad prawn]

rejoin this server bro

[dapper flower]

lets give it a shot

[chrome beacon]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/World.html#playSound(org.bukkit.entity.Entity,java.lang.String,org.bukkit.SoundCategory,float,float,long)

[dapper flower]

test

[glad prawn]

yay

[dapper flower]

fixed

[glad prawn]

🤑🤑

[chrome beacon]

@wraith delta API method with seed

[eternal oxide]

oh

[chrome beacon]

No need for packets

[eternal oxide]

yeah

[dapper flower]

still 0 idea why that happened tho lmao

[eternal oxide]

is that new?

[echo basalt]

Prob not

[wraith delta]

nice! will have to give it a try tomorrow. thanks for the find

[eternal oxide]

Doesn;t seem to be on Player in 1.19.4

[chrome beacon]

🤷‍♂️ could be

[scarlet gate]

I have an interactive harvest plugin (player right clicks crop and then the crop breaks and automatically plants seeds)

So I am handling the dropping of the items

[eternal oxide]

@wraith delta what does cave18 sound like?

[wraith delta]

https://youtu.be/JiIpml55jgA?t=108

copied the video at the time of 18 - its for dungeon door. ima remove the embed

I modeled a dungeon using bdengine, and used code to grab the entities and animate it as a open/close lifting door

[eternal oxide]

ok, for older versions this seems to play it```java
long seed = 17;
float volume = 1;
float pitch = 0.5f;

        Location location = player.getLocation();
        double x = location.getX();
        double y = location.getY();
        double z = location.getZ();
        
        SoundEvent event = SoundEvent.createVariableRangeEvent(ResourceLocation.tryParse("minecraft:ambient.cave"));
        ClientboundSoundPacket packet = new ClientboundSoundPacket(Holder.direct(event) , SoundSource.AMBIENT, x, y, z, volume, pitch, seed);
        
        ServerGamePacketListenerImpl connection = ((ServerPlayer) NMSUtils.getServerPlayer(player)).connection;
        connection.send(packet);```

newer API has teh seed value so you don;t need nms for that

[chrome beacon]

Did you brute force the seed

[eternal oxide]

yes

[wraith delta]

found a github with the seed https://raw.githubusercontent.com/Owen1212055/mc-sound-seeds/main/sound_seeds.json

CTRL+F cave18 - {"id":"minecraft:ambient/cave/cave18","seed":-4481247781671450987}

[eternal oxide]

17 works for me

[wraith delta]

Does this work for 1.20?

[eternal oxide]

no idea

I wrote it on 1.19.4

[wraith delta]

Where did SoundEvent come from, im not seeing that in jdk17, 1.20.2

[eternal oxide]

a seed of 17 works perfectly on 1.19.4

its NMS

[wraith delta]

ive never used NMS. i avoided it for any risk of version complications

[eternal oxide]

then you need to use protocolLib if you can;t do nms

[wraith delta]

but wait, the api method the other guy sent, we have the seed..

[eternal oxide]

on newer spigot, yes

[wraith delta]

ah maybe not 1.20.2

[wraith delta]

Heres the door open/close WIP using warden sound since i couldnt get the cave yet lol. using display entities so no r packs

[glad prawn]

dam

[scarlet gate]

Or PacketEvents is also a good option, I find it a fair bit easier to understand too personally

[smoky anchor]

Small suggestions that could maybe help
You can make all the display entities ride a single display entity and move just that one -> that will make all of them move at once and the weird jump, just like the one at the end, will not happen
Since idk what 1.20.x we have teleportation interpolation too, you could probably use 1 or 2 ticks to make it a bit smoother, your video seems a bit jittery

[eternal oxide]

?nms

[undone axle]

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

[eternal oxide]

that was for me to get teh currnet specialsourcce version

[wraith delta]

its a work in progress, but just to inform idk if the suggestion still applies, the door is spawned at multiple locations using a console command run from code. The code then has to retrieve those locations to read your key to unlock it and animate them even after the server restarts.

[eternal oxide]

Just to note, 17 as a seed also works on 1.20.6 as well as 1.19.4

I just tested it using my code and API

In current APIjava player.playSound(player, "minecraft:ambient.cave", SoundCategory.AMBIENT,1f, 1f, 17L);

[wraith delta]

wdym by ticks? I grab the entities and put them into a list, then foreach the list in a runnable. im not able to check for the main one since its created by command

[smoky anchor]

You can set how long the interpolation should last
You can either just teleport the root entity, that would hold all the entities, to the "open" position and set the interpolation to the amount of ticks you want the door opening animation
or move it bit by bit and have low amount of ticks for smooth movement, you can use different curves in this case, not only linear one

Also, doing anything by calling a command from code is just terrible, there has to be a better way to do that

[wraith delta]

bd.setInterpolationDuration(60);
bd.setInterpolationDelay(1);
bd.setTransformation(transformation);
```Yea i use this

[wraith delta]

the only time the command is run is when I choose the locations that the doors will exist

[smoky anchor]

Aaah ok, then it's probably just my eyes playing tricks

[smoky anchor]

oh I see, then I misunderstood what you meant

[wraith delta]

i modeled the door in bdengine and used the exported command in the code, inputting the location variables that saves it to config etc

trying to read those entites after being spawned isnt the easiest lol

[spice burrow]

anyone here know what they're doing when it comes to logarithmic functions 💀

[frail pilot]

?

[spice burrow]

I'm working on a leveling system right now and I'm trying to understand them but I am not exactly your math professor

[smoky anchor]

?ask but idk if this is best place for math

[undone axle]

If you have a question, please just ask it. Don't look for staff or topic experts. Don't ask to ask or ask if people are awake or available. Just ask the question to the channel straight out, and wait patiently for a reply. Make sure you use the right channel regarding the topic of your question. Create a thread in case the channel is already in use!

[wraith delta]

thanks for this ill have to try it on 1.20.6 sometime, but in 1.20.2 it wants me to remove the last arg (seed)

[eternal oxide]

yep its a new addition to the API

older version you will have to use ProtocolLib or NMS

[spice burrow]

ya I figured 😂

anyways, I'm trying to create logarithmic function that dictates player level/xp. leveling up fast at the beginning, and plateauing at the end. I'd like xp values for the max level to be around 80,000,000

[frail pilot]

Ln is a function. Basically, it allows you to transform a product into a sum

It's derivative is 1/x

Which means that when you have hight value of x it increase slower

That's why it's quite convenient for leveling functions

[spice burrow]

interesting, ill probably try to play with desmos until i understand it.. my issue is finding xp/level conversions from said function

[frail pilot]

Well you probably have something like level=ln(XP)

Ln being the logarithm

Note that level=ln(experience) means that experience=exp(level)

Exp being the exponential function

[spice burrow]

hmm interesting

i keep forgetting log is the inverse of exp

[frail pilot]

But if you want specific value of experience for each level you might need something a bit more complex

Nothing very hard but it involves to do some maths

[spice burrow]

maths i shall attempt to do then, i could just hardcode values but what's the fun in that

[lilac dagger]

you can look at different growth rates using a graphing calculator

really useful stuff

[short drift]

In 2024, what are my options for displaying texts and graphics to the players?
8 years ago there was titles and chat and inventory menus .. and .. I think that was about it.

[frail pilot]

Menu can display things

I mean inventories

Resources packs can do the job

[short drift]

Well, I did mention that. There's nothing, no new techniques?

[frail pilot]

Otherwise using a map

Or

You go the hard way

With display entity

[short drift]

Yeah, like holograms?

[frail pilot]

Basically

But you might be able to do better

If you lock the player camera

[echo basalt]

display entities and some raycasting

[frail pilot]

And his movements

[short drift]

Do you know anything particularly impressive you could link me as an example?

[frail pilot]

You can display whatever you want

[echo basalt]

Maps and item frames

7smile7 once sent a gif here hold on

[short drift]

Right. But those would be stationary.

Unless you mean like the map UI when looking at a map.

[echo basalt]

https://media.discordapp.net/attachments/995870168230137907/1011194899896475728/select3.gif

[short drift]

Right. So basically there's nothing new and ground breaking in UI since the last time I've been meddling with MC 8 years ago.

[echo basalt]

Inventories changed a bunch

[short drift]

What's up with those?

[echo basalt]

Well

You can set custom backgrounds and such

[short drift]

What would that look like?

[echo basalt]

Pair that with hiding the player's inventory and you end up with some nice menus

[short drift]

Would you still be constrained to display the things in grids?

[echo basalt]

This but the inventory is hidden

[short drift]

Right. That's pretty nice.

https://cdn.discordapp.com/attachments/1232644083655114812/1232644083823153162/seasons_calendar.gif

[echo basalt]

Yep

[short drift]

I also saw something like this.

[echo basalt]

That's just the same principle but you change the title a bunch

[short drift]

So that's like ... resource pack + data pack + code or something?

[echo basalt]

With some packet magic

Resourcepack + code

[short drift]

I might look into that.

[echo basalt]

I've also managed to make individual slot background colors

[short drift]

Thank you.

[echo basalt]

:)

You can pair that with the others to, for example, highlight / lock an item

[shadow night]

Can you draw like that

[echo basalt]

You can

It's really low res

[shadow night]

Make a buffered image to this type of inventory converter

[echo basalt]

(it was a poop emoji)

[shadow night]

Could've guessed that

[eternal oxide]

?stash

[undone axle]

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

[shadow night]

Make 4 colors per slot fr fr

[echo basalt]

I used it for this

[echo basalt]

it's possible but annoying as shit

[shadow night]

Open source when

[spice burrow]

what are your thoughts on something like this? Level = Math.max( Math.floor( constA * Math.log( XP + constC ) + constB ), 1 )

[echo basalt]

tbh the guy that paid for this did exit scam me so I'm morally obligated to release this

[quaint mantle]

Can I know how did you made this?

[echo basalt]

What part

Ah

That one

That's 7smile7's thing but I've worked on a really similar system

Basically maps on invisible itemframes

Everything packet-based

[quaint mantle]

How do you do the overlay thing?

[echo basalt]

Do a little raycasting, modify the image

[frail pilot]

That does the job, with the three constants you can adjust it it's quite nice

[shadow night]

I only need the colorful squares in inventory thing

[quaint mantle]

Thanks

[echo basalt]

It's a single pixel scaled up to 15*15 and some negative spacing stuff to make it all space evenly

For height I'm pretty sure I used multiple fonts that just had different ascents

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

[quaint mantle]

Isn't that what a plugin used to display player heads on chat?

[echo basalt]

no clue

I wrote this myself

[spice burrow]

cant take all credit i had my buddy from uni help but im quite proud of the constants i proposed and he created for me 😂

[acoustic pendant]

What should i be using? I mean, what is more efficient

storing the name of the world or the world it self

[echo basalt]

.

[acoustic pendant]

I'm loading the world

[sullen canyon]

uuid

[lilac dagger]

the uuid of the world is the best

[acoustic pendant]

okay, i'll do that

thanks

[royal heath]

wtf is this spigot

[young knoll]

Yeah

Just some resource pack magic

[royal heath]

I just started getting back into spigot since around 2020

I did not know you could do that that is very cool

[eternal oxide]

@young knoll When was this merged? https://hub.spigotmc.org/stash/projects/SPIGOT/repos/craftbukkit/commits/8e162d0083aa05bd3b4ec8972093fe7e9e9b53b0

[young knoll]

It says on the PR if you can see it

Nov 17

[eternal oxide]

really? Odd it didn;t show up in 1.20.2 for SoSparkly

he must just be mistaken

[worldly ingot]

I got 100 stars on VeinMiner on GitHub

[young knoll]

34 forks

[royal heath]

You made VeinMiner? You're a blessing to us all

[young knoll]

Now he just needs to port the client mod to all the other modloaders

Kek

[worldly ingot]

On the todo list!

[young knoll]

What about quilt!

[eternal night]

what about lynxloader

[worldly ingot]

is quilt different from fabric? I thought it was a fork with just some extra methods

[young knoll]

I think so

Isn’t that also the case with neoforge

[worldly ingot]

For now it is, yeah

They plan on breaking relatively soon afaik

[young knoll]

Idk if you need different metadata files for each tho

[eternal night]

Hate it when forks break away from their upstream

didn't quilt want to do the same tho?

[young knoll]

They really should have picked more unique names then

Especially neoforge

[eternal night]

Quilt is a hard fork of Fabric

Yea looks like it lol

[valid burrow]

woah

[molten hearth]

not a problem

they will die shortly after 😭 🙏

[young knoll]

Ooooh shots fired

[eternal night]

[vast ledge]

If i didnt know what you were talking about, that would sound like you're a psychopath

[eternal night]

Who knows, maybe I am

[molten hearth]

technically

the bottom part of a fork could snap from the handle

[vast ledge]

probably

[devout kite]

I saw that there is a methode on player where u can show the DemoScreen, and can edit it with resource pack. My question is if u can edit the buttons on what they do?

[young knoll]

Sadly no

[devout kite]

Not eaven on invclick event?

[young knoll]

Nope, it’s not an inventory

[devout kite]

Sad 😦

[orchid hinge]

which fuction changes the name above someones head? i forgor

[valid burrow]

the name above someones head?

there is no such thing directly you can either use a scoreboard or armorstand

[young knoll]

(display entities better)

[alpine urchin]

congratulations

next up is 200

[pseudo hazel]

well technically next up would be 101 🤓

[lilac dagger]

not if github implements doubles for stars in a future update

[pseudo hazel]

wtf are doubles

[lilac dagger]

i'd love to be able to give 0.99 stars

[alpine urchin]

i only count in hundreds

[lilac dagger]

double?

[pseudo hazel]

oh

[worldly ingot]

me when I'm learning java for the first time

[alpine urchin]

honestly

[orchid hinge]

if i use scoreboard will i still be able to have a scoreboard on the sidebar?

like these ones?

[valid burrow]

yea

if you do it propperlly

[orchid hinge]

im bad at doing it properly but ill try thanks

[quaint mantle]

Spigorge++

[pseudo hazel]

yes you can have multiple scoreboards and display them all diffently

[fathom hazel]

Hi

[quaint mantle]

Doesn't it overwrite the current one if they are on the same display?

[pseudo hazel]

yes

you can only have one scoreboard (or objective i dont remember) per display at any one time

for example my plugin has multiple scoreboards that all use the sidebar, but only one of them can be visible at a time

[warm galleon]

hello i need help with the redprotect plugin

[fair rock]

Is there a option to run a method after all plugins got enabled?

Why?
I want to make a core plugin where i can register services and managers for some stuff like database, particle, whatever
Now im trying to learn Hibernate for work. When i have a core plugin that means i have to add the "AnnotatedClasses" to Hibernate and create then a session factory

Like:
Core enabled -> other plugins can register annotated classes to hibernate -> builds sessionfactory (After every plugin got enabled)

[pseudo hazel]

you can set your plugin priority to be lower so more plugins load before yours

there may be an event or something, idk

[young knoll]

ServerLoadEvent

Or schedule a task in onEnable

[chrome beacon]

ServerLoadEvent should work

[scarlet gate]

Is there an event that gets called when harvesting honeycomb from a beehive?

I assumed BlockDropItemEvent might cover it but it appears not

[eternal oxide]

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

[scarlet gate]

Ooh

perfect

thanks

Doesn't seem to work for some reason

[eternal oxide]

?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.

[scarlet gate]

Well, it's just not triggering when I harvest the honeycomb

[eternal oxide]

?paste code for the event

[undone axle]

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

[scarlet gate]

It's not even running the code, I have a breakpoint on the first line of both BlockDropItemEvent and PlayerHarvestBlockEvent, when harvesting honeycomb from a beehive neither are triggered, when harvesting a sweet berry bush both are triggered

[pseudo hazel]

did you register the event listener

[tall dragon]

well it got called when they did it on a sweet berry bush

so yea they did

[pseudo hazel]

oh mb

i cant read

[tall dragon]

i suspect the beehive just doesnt use any of those events. might just have to just InteractEvent and make your own checks

though it is odd that it does not call PlayerHarvestBlockEvent. i would think that it would

on the other hand. they can also be harvested by dispensers so that event woulnt rlly cover everything

[scarlet gate]

What gets called when using a bottle on a cauldron, could it be the same event as that? (Thinking along the lines of water in cauldrons)

[tall dragon]

well there is a CauldronLevelChangeEvent

[scarlet gate]

Ahh probably not that then haha

[eternal oxide]

if I knew how bee hives worked I'd test it

[scarlet gate]

Is there some sort of plugin that just logs to console events being triggered

[eternal oxide]

yep harvest event never fired for Beehive

[short drift]

What is the go-to method for checking whether the player has their hat layer visible or not on the player's skin?

[dawn flower]

why is the inventory name of the event inventory in InventoryOpenEvent always Crafting?

oh wait im dumb

[pseudo hazel]

dont compare inventory names to check if you have the right menu reference

[dawn flower]

i'm not doing that

[pseudo hazel]

okay good

just so you know xD

[dawn flower]

well i kinda am but if it conflicts with another inventory, it wouldnt really do anything

[pseudo hazel]

seems to be a very common mistake

wdym by kinda

[dawn flower]

im basically closing the player's current gui when they open another gui so it resets their mouse position to the middle but i don't want it to do that for some guis

like the ah gui

[pseudo hazel]

so you checking the inventory based on the name

[blazing ocean]

i genuinely don't get how people can make GUis without libs such as incendo/interfaces

(or, well, the kotlin version)

[shadow night]

Did you say kotlin

[blazing ocean]

bro actually stfu

[short drift]

Anyone know anything about using ProtocolLib?

I can't get any packets detected.

Oh, wait.

Wrong file.

https://pastebin.com/u3JyWuj2

And registering:

    private void registerHatDetector() {
        System.out.println("CriticalFixes: Loading HatDetector.");
        var hatDetector = new HatDetector(this, protocolManager);
        protocolManager.addPacketListener(hatDetector);
    }

[tardy delta]

we still using pastebin in 2024?

[short drift]

Yes. I have lifetime pro account.

[tardy delta]

you what

[short drift]

They were selling those at one point so I jumped at the chance.

[blazing ocean]

https://pastes.dev my beloved

[short drift]

But if anyone can tell me what I might be doing wrong with ProtocolLib, I would appreciate it.

Constructor runs. Whitelists run.

But that's it.

[tardy delta]

paste.rs/web my beloved

ngl its a piece of shit

ah they updated it and its even worse now

[ivory sleet]

legit n1 thing people confront you with

[blazing ocean]

why does nothing of that sentence make sense

[ivory sleet]

whaa

[worthy yarrow]

I think he meant legit anything people confront you with?

Idk I’m just enjoying this view

[pseudo hazel]

number 1

[worthy yarrow]

Con check general, bet you’d like to wake up to this everyday (so would I)

[pseudo hazel]

cuz I made my own framework for menus 😛

[ivory sleet]

ooo

yea i use nms

best gui framework out there (not really but really)

[worthy yarrow]

Ew

[pseudo hazel]

best framework for making frameworks

but no(t) really

[remote swallow]

pineapple has best gui

[ivory sleet]

no but its nice cuz like, well I do use fabric so i got mixins but yea
