help-development

[torn shuttle]

and not like 6 laid back relaxed days, no, 6 days just grinding away at it

[humble tulip]

Typically you develop on the lowest version you wish to support

If you wanna support 1.16+ develop on 1.16

[torpid sapphire]

so forwards compatibility is easy

backwards not so much

or how should i understand that

[quaint mantle]

hey! ive been learning kotlin for plugin development, but im not really sure how to start making one in the language. i want to make a basic plugin that i can use to build other plugins out of, but i dont really know where to begin with making one! any help would be appreciated :D

[torpid sapphire]

https://www.spigotmc.org/wiki/how-to-use-kotlin-in-your-plugins/ found this on the wiki

all other guides on the wiki should still work, api is the same

[quaint mantle]

thank you :D

[torpid sapphire]

youd just have to rewrite the actual code snippets

but that should be simple enough

[sleek island]

how should i apply upwards knockback

[young knoll]

positive Y velocity

[stuck oar]

how do i register a command that is like in my main class

getCommand("levelup").setExecutor(this); i have this but it doesnt work

[echo basalt]

wtf bukkit

it's 4am and I gotta release this shit in like 4 hours

[sly topaz]

why are you doing reference equality on entities

[echo basalt]

Testing for weird parity issues

(we have like 2 different custom entity systems at work and they're tripping up)

In specific, I spawn an entity -> convert it to a "component entity" (tracks with entity ids) and apply a model (converts back to the real entity) and that's throwing errors

Solution is to load the chunk. Fairly dumb imo

[restive sierra]

hi guys

i really need help

there's a command somewhere for that

in short you gotta verify

[restive sierra]

oh

il do it rn

this is the dir for my files

[quaint mantle]

Just split jars for each platform 💀

[dawn flower]

TurboPlaceholder<?> placeholderSyntax = syntaxParser.parse(parsedPlaceholder, TurboPlaceholder.class);

Object result = placeholderSyntax == null ? "<" + placeholder + ">" : placeholderSyntax.get(parsedElement);

if (string && placeholderSyntax != null && result != null)
  return placeholderSyntax.toString(result);

is there a way to cast it? because i know for a fact that result is an instance of TurboPlaceholder's generic

String toString(T object)
T get(ParsedElement element)
these are the methods

[acoustic shuttle]

use intelliJ'

[near furnace]

let ma man use vscode 😭

[acoustic shuttle]

Skript ahh text editor 🙏

[near furnace]

guys, which is better? using minecraft development kit or doing it manually with gradle and using artifacts

[pseudo hazel]

?img

[undone axle]

Can't send images? That's because you're not verified! Use !verify to complete verification.
Alternatively, you can upload screenshots to any image hosting site and share the link.

Here's some screenshot utilities that you can use to upload images.
Lightshot: https://prnt.sc
Imgur: https://imgur.com/upload
Flameshot: https://flameshot.org

[pseudo hazel]

use the plugin

dont use artifacts in any case

build using gradle or maven

[near furnace]

some people say to do it manually

some say use the plugin

which one is better if you are going to create a full fledge plugin to sell

[pseudo hazel]

do what manually

create build.gradle?

[near furnace]

like not use the plugin

[eternal oxide]

MDC really should not be used by beginners. Its for more advanced users to skip mundane tasks.

[acoustic shuttle]

Use the plugin lol

Whats the point of setting it up manually?

[eternal oxide]

to learn

[acoustic shuttle]

ig

[pseudo hazel]

but who likes learning anyways

[eternal night]

the plugin also has to create a not too optimal build.gradle.kts as it supports like everything

[eternal oxide]

yeah, lets get a room, fill it with monkeys at keyboards.

[eternal night]

if you are just going to compile against spigot 1.21.1, you can create a much neater build.gradle.kts than the plugin can

[near furnace]

yay i can send pictures now! :)

[pseudo hazel]

I just create the project using the plugin and then edit it to what I need

but I guess that requires you to know what you need

[eternal night]

or that xD yea. But I mean, a plain build.gradle.kts for spigot is like, 6 lines after gradle --init -dsl kotlin

[quaint mantle]

hey guys. does anyone know good tutorials that explain how serialization to a yaml file works? I understand but it's just confusing how come there is a map of Strings and Objects - how does an object get stored to config as a readable value?

(spigot configurationserializable)

like i dont get how itemmeta saves in the serialize method of ItemStack

[sly topaz]

ItemMeta is a snapshot of an item stack

all it does when serializing is taking all of its fields, and putting them in a Map where the keys are the field names and the values are well, the values of these fields

some encoding might be done in the process to obtain a a more compact serialiazed form and whatnot, but that's the gist of it

[eternal oxide]

?stash if you want to see the source

[undone axle]

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

[astral pilot]

how do you clone GameMode

[eternal night]

why would you clone GameMode

[quaint mantle]

oh interesting. i just dont understand how like its just "result.put("meta", meta);" to serialize it when it has so many variables. sorry im a bit dumb XD

[astral pilot]

to store previous gamemode of player

previousGameMode() doesn't seem to work

[eternal night]

I mean, you just store the returned GameMode in a variable

it is an enum

[astral pilot]

wouldn't that store a reference

[eternal night]

a reference to an immutable enum constant yes

[shadow night]

Bro has no idea what an enum is

[astral pilot]

so ig when the gamemode changes, it wont be reflected to that variable right?

[eternal night]

It would not no

calling getGameMode would simply return a different value

but the referenced enum instance itself is immutable

[astral pilot]

ok thanks

[sly topaz]

that's because it delegates the serialization to the implementation of the ItemMeta (CraftMetaItem)

this is the serialize method for default ItemMeta impl

though since meta has various subclasses, each sub-class has its own serialize method where they put their own data into the map builder and pass it along to the parent

[shadow night]

why not link the original source

[sly topaz]

that's generally how serialization of complex object graphs is done, albeit the one bukkit uses is pretty barebones to say the least

[sly topaz]

making an account and accepting the CLA just to show a piece of code is eh

[eternal night]

you don't need to sign the CLA to view the code

[shadow night]

You don't need an account either kek

[sly topaz]

I might be remembering things wrong but wasn't it the case that you couldn't see the craftbukkit source unless you created an account and agreed to something first?

[eternal night]

that is for PRs

[quaint mantle]

dang so complicated

[sly topaz]

ah, makes sense

[shadow night]

If that was the case buildtools wouldn't work

[sly topaz]

it looks daunting but all it is doing is serializing each field the ItemMeta to a format the YAML specification supports

there are fancier serialization frameworks out there such as the one GSON uses which scale much better for this kind of complex object graph

[quaint mantle]

    @NotNull
    @Utility
    public Map<String, Object> serialize() {
        Map<String, Object> result = new LinkedHashMap<String, Object>();

        result.put("v", Bukkit.getUnsafe().getDataVersion()); // Include version to indicate we are using modern material names (or LEGACY prefix)
        result.put("type", getType().name());

        if (getAmount() != 1) {
            result.put("amount", getAmount());
        }

        ItemMeta meta = getItemMeta();
        if (!Bukkit.getItemFactory().equals(meta, null)) {
            result.put("meta", meta);
        }

        return result;
    }```

wait so where here does it delegate to the implementation of itemmeta?

[pseudo hazel]

by putting in the meta

and the meta will serialize itself

similar to the itemstack

[quaint mantle]

interesting

so thats like a requirement of maps?

or smthn?

[eternal oxide]

Maps take whatever you tell them to accept

basic java

[sly topaz]

somewhere along the call chain, that Map will be iterated in order to create the yaml structure, and when setting the value corresponding the meta key, it'll call serialize on the Object (or rather, the ConfigurationSerializable)

[quaint mantle]

oh interesting!

sorry lol i appreciate your help. i always like to understand as much as i can about what im doing haha

[tawdry echo]

\

[sly topaz]

it's fine, we're all here to help

[quaint mantle]

🔥 yeah i understand like basic OOP and inheritance and stuff but all this nitty-gritty is pretty confusing for me haha

i wonder how painful it would be to serialize to a sql database 🤣

[shadow night]

pretty easy actually

[sly topaz]

I mean, you don't really have to think of all of this when serializing stuff, often times you can just let the serialization framework do most of the work for you

[upper hazel]

question to those who know is there any sense to create class loading in runtime api plugins together with the build system or is it of no use?

[sly topaz]

and since things like items are actually serializable in multiple ways (you can serialize them as binary data by calling ItemStack#serializeAsBytes for example), all you have to do is pass that along in your query as a VARBINARY or a Blob

u hm

a h m

is there anything wrong with my code that spigot dislikes?

[sly topaz]

did you define the command in your plugin.yml?

[eternal oxide]

no command in plugin.yml

[sly topaz]

then that's your issue

[near furnace]

owh

... my bad

how do you guys read this goobledy gock

this stacktrace

[sly topaz]

you just have to read the first line

[eternal oxide]

its easy once you understand it.

[sly topaz]

the rest is just the call stack

[near furnace]

which line gave you guys that something was wrong with the plugin.yml

[sly topaz]

it says me.lolnypop.myplugin.myplugin.getCommand(String)" is null

getCommand is a method from JavaPlugin

[near furnace]

mhm

i get it

[eternal oxide]

a stack trace is just a list of all calls currently on the call stack (in order). There is always an error and usually an explanation.

[near furnace]

spigot was unable to get the getCommand() since plugin.yml was not initialized

[sly topaz]

and the getCommand documentation says

[ivory sleet]

when you read stacktraces, usually reading the lines that involve your code (the classes and packages) will give away what went wrong

[sly topaz]

usually, you'll see the exceptions the method throws listed in the method documentation too

[near furnace]

correct?

[sly topaz]

yes, basically

[ivory sleet]

I think plugin.yml was initialized for you still?

[sly topaz]

sometimes, due to there being too much abstraction going on, the cause might be buried deep into the call stack, but often times it's enough to check the first few lines of the stack trace to know

[near furnace]

im slowly learning to understand these stuff :)

[ivory sleet]

its just the command declaration in plugin.yml is missing

[near furnace]

i didnt register the command in the plugin.yml at first, now i did lets see if it works

[quaint mantle]

oh interesting, how would you deserialize?

[eternal oxide]

its a common error here so easily recognised.

[ivory sleet]

Your plugin would still run fine if you didn’t call getCommand(…).setExecutor(…) even if the command is missing in plugin.yml

[pseudo hazel]

deserializeFromBytes or something

[sly topaz]

Spigot already has a way to dynamically load libraries at runtime, see the libraries section described here: https://www.spigotmc.org/wiki/plugin-yml/#wikiPage

[eternal oxide]

so long as you caught the error and didn;t allow it to propogate through the onEnable the plugin would still run

[sly topaz]

just calling ItemStack#deserializeBytes(byte[] data) (though now that I look at it, this is Paper-only API, woops)

[quaint mantle]

i was about to say i cant find it hahaha

[upper hazel]

What do you think if we make some api plugin and add a system of its loading in runtime and update api maintaining old versions of the plugin (package names, methods, etc.) and change only the logic, then it turns out it will not be necessary to update the version of api in the build system at the first loading of classes?

[near furnace]

Hey there, why wont there be a auto fill suggestion? (true/false)

package me.lolnypop.myplugin.commands;

import me.lolnypop.myplugin.myplugin;
import org.bukkit.ChatColor;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;

            plugin.getConfig().set("feed-player", true);
        } else if (args[0].equals("false")) {

            return true;
        } else sender.sendMessage(ChatColor.translateAlternateColorCodes('&', "&c" + "Please select between true or false"));

        return true;
    }
}``` 
My code

[ivory sleet]

You mean like an extension system?

[quaint mantle]

do you have a tabcompleter

[near furnace]

is that a spigot interface?

[pseudo hazel]

implement TabExecutor

then you have onCommand and onTabComplete

[upper hazel]

Well, if you can call it that, yeah.

[quaint mantle]

dont u also have to register it

[pseudo hazel]

yes

[ivory sleet]

Like are we talking placeholder api expansion/luckperms extension stuff?

I mean papi is a bad example since their classloaders are leaking iirc

[upper hazel]

yes addons etc

[near furnace]

ok, the tabexecute implements both commandexecutor and tab executor?

[pseudo hazel]

yes

[near furnace]

good to know that ;)

[upper hazel]

runtime class loading for auto update

[pseudo hazel]

iirc its just an interface that literally just extends commandexecutor and tab complete

[upper hazel]

no change maven version

[ivory sleet]

I mean that’s fine, its completely doable and valid to implement such a feature

[near furnace]

i was thinking, if there isnt any tab completion how would people know its a true or false answer haha

[quaint mantle]

tab completion is so cool

[upper hazel]

As a result, the person just adds the necessary classes to the project via maven, but the logic of these classes is changed in runtime.

[ivory sleet]

You describe it a bit odd for being an addon system

[near furnace]

I've recently heard about command frameworks, could you quickly explain what they actually do or if they help or not

[quaint mantle]

im ngl im not the one to ask

im a noob

[ivory sleet]

It’s code people wrote to make writing commands easier

[upper hazel]

maybe but it wasn't my idea

my friend create this system and now we think how use it

[ivory sleet]

That includes parsing arguments, structuring literals and argument and deal with tab completion automatically and thread execution coordination

[sly topaz]

there's a whole lot of cruft when it comes to commands, these frameworks help with that

[ivory sleet]

There are a lot of command frameworks that utterly suck so its far from pure good

[quaint mantle]

yo @sly topaz do you know any good serialization tuts for bukkit / spigot or whatever that i can watch? its hard to know what info is reliable

[near furnace]

woah niceeee

[ivory sleet]

The spigot wiki has some info about it relly, not sure how “updated” it is

[quaint mantle]

i think i found one from 2016

https://www.spigotmc.org/wiki/introduction-to-serialization-section-2/

[sly topaz]

main ones are dealing with cross-platform and cross-version abstractions as well as integrating with brigadier to support client-side suggestions, among a bunch of other stuff

[upper hazel]

The fun thing is that we make an api plugin with addons system and then we only realized at the end of the work that addons are not needed because the api user interacts with the code and in any case the classes will have to be loaded through the build system and the only benefit I saw in this is the ability to automatically change the logic of classes in runtime.

[sly topaz]

if you want to utilize commands to their fullest, it's better to go with a command framework like cloud or CommandAPI

[ivory sleet]

or just brigadier

you don’t have to use a third party framework for the sake of it

[sly topaz]

Spigot doesn't have support for it yet

[ivory sleet]

you can invoke on nms

[sly topaz]

yeah but that's just messy

[ivory sleet]

a little bit

[sly topaz]

just use the framework at that point

[rotund orchid]

there is a problem with playerkits every time I try to move the kit to another slot it appears 2 times in the position I inserted and in the previous position how do I solve this Bug?

[ivory sleet]

Eh, depends I mean its like some extra casting and one or two extra method calls

Only argument against brig is that it doesnt support annotations

[sly topaz]

yeah, for one version, then when updating it'll cause issues or when you want to support more versions and what not, it is just not a good choice if you consider the future scaling of your project

[ivory sleet]

Which seems to be a huge deal breaker to most

[near furnace]

Ahhhh, even though there are more than 1 arguments, the game still sets the value to true! Idk why I made sure in the code that if args.length > 1 then it should say Invalid Syntax and return true;

[rotund orchid]

there is a problem with playerkits every time I try to move the kit to another slot it appears 2 times in the position I inserted and in the previous position how do I solve this Bug??????

[ivory sleet]

its stayed quite consistent for the time being, if it changes in the future I reckon you just update accordingly and it would imply support for the future

But sure, spigot does prioritize ver compat

so its maybe not aligned with their core values

[sly topaz]

only recently has the version been removed from nms packages, if you want to support older versions then you have to do the whole thing with reflections or creating interfaces which have an impl per version, it is just messy

[pliant topaz]

thats cause you dont check any other value so they're just completely ignored

[ivory sleet]

Even better is paper w its little abstraction on top

[sly topaz]

then when you want to move to another platform, you have to do all your ccommands again

[rotund orchid]

there is a problem with playerkits every time I try to move the kit to another slot it appears 2 times in the position I inserted and in the previous position how do I solve this Bug?

[near furnace]

} else if (args.length > 1) {
            sender.sendMessage(ChatColor.translateAlternateColorCodes('&', "&c" + "Invalid syntax!"));
            return true;
        }```

This is the part of the code

[pliant topaz]

but why should it say invalid syntax?

[sly topaz]

in paper it is fine since they got support for it, but if it comes to touching internals, I can't recommend it to beginners in good conscience

[ivory sleet]

I mean most people here don’t account to write platform agnostic in the first place

[rotund orchid]

there is a problem with playerkits every time I try to move the kit to another slot it appears 2 times in the position I inserted and in the previous position how do I solve this Bug?

[near furnace]

I want it that, if the player provides more than 1 arguments, no matter what it is, it should provide a "Invalid Syntax"

Even if somebody writes /setfeed true oaijeoaij, There are two arguments here and i want to say Invalid Syntax here

[sly topaz]

I mean, it does already no?

[near furnace]

but instead the game sets it to true

[rotund orchid]

there is a problem with playerkits every time I try to move the kit to another slot it appears 2 times in the position I inserted and in the previous position how do I solve this Bug?

there is a problem with playerkits every time I try to move the kit to another slot it appears 2 times in the position I inserted and in the previous position how do I solve this Bug?

[pliant topaz]

but the second one is just ignored

so it doesnt matter

[sly topaz]

you have to return false if the command failed

[pliant topaz]

its only a restriction to the player

[near furnace]

owhhhh

[sly topaz]

but still, that part of the code shouldn't be executed, make sure your if statement is in the right place

[sly topaz]

why are you spamming your message

[ivory sleet]

but returning false prompts the sender with an ugly message, a lot of devs just return true regardless and send messages to the sender themselves

[near furnace]

i mean i just wanted if the player says two arguments "/setfeed true aoijoiaej" or even gibberish "/setfeed oiajeo oijse", as long as there are two arguments, i want it to send an invalid sytax message and cancel the code yk

ok ill try it with return false;

[rotund orchid]

Because don't you answer

[sly topaz]

the channel is run by volunteers, people will answer when they want to answer

[pseudo hazel]

you check in your command if there are too many arguments

[sly topaz]

being obnoxious about it doesn't help

[near furnace]

Hey there, i know its a bit frustrating but please don't spam. Sometimes i have to wait to get a proper reply too :)

[ivory sleet]

Do u have any code to showcase?

[near furnace]

idk if i should say this, but i think people would appreciate if you would share the code, and shared the stacktrace before asking for help repeatedly

[pseudo hazel]

?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.

[rotund orchid]

there is no error code I get the kit in the slot where the moved is in the previous slot and I cannot send test videos

[pseudo hazel]

but you have written code to do this behavior right?

are you a developer or a server owner?

[near furnace]

Hey there i changed it to return false, still doesn't behave like the way I want it to. I also mentioned that

    plugin.getConfig().set("feed-player", true)
}```

I mentioned only the at arguments index 0, if its "true" then set it to true, but how do I make it that if there are multiple arguments even if the "true" is at index 0, it should cancel everything and provide invalid syntax :)

[pseudo hazel]

check the command on amount of arguments

if its more than you expected, return the error

[near furnace]

 if (args[0].equals("true")) {
            plugin.getConfig().set("feed-player", true);
        } else if (args[0].equals("false")) {
            plugin.getConfig().set("feed-player", false);
        } else if (args.length > 1) {
            sender.sendMessage(ChatColor.translateAlternateColorCodes('&', "&c" + "Invalid syntax!"));
            return true;
        } else sender.sendMessage(ChatColor.translateAlternateColorCodes('&', "&c" + "Please select between true or false"));```

here is my if statements

[hushed scaffold]

#help-server seems like the better place since I'm 90% sure you're using an existing plugin

[pseudo hazel]

well you would have to return before you change the config

like perform all your checks that prevent it from working first, and then do stuff with whats left

in this case

args[0] has nothing to do with the overall size

so if you check that first, it will skip the size check

@pseudo hazel thanks, idk why it didnt came into my mind earlier but will this work? im now checking for the argument length

if (args[0].equals("true")) {
            if (args.length > 1) return false;
            {
                plugin.getConfig().set("feed-player", true);
                sender.sendMessage(ChatColor.GREEN + "Set the value to true");
            }```

[pseudo hazel]

yeah

[ivory sleet]

2 things, check args.length before invoking args[n]

don’t forget to save the changes to the config

(there’s a plugin.saveConfig() method)

[pseudo hazel]

if this command only supports 1 argument I would check it even before seeing if args[0] is true

[near furnace]

yippee lemme try it and see, idk sometimes these simple java stuff dont come into my mind and i go asking dumb questions

[pseudo hazel]

like if args.length != 1, you done messed up

[near furnace]

okie

[upper hazel]

How to add a separate module to the repository in a common project. I have several plugins

[ivory sleet]

maven?

[upper hazel]

i mean add to repository for use in build system

[eternal oxide]

?modules

there is a command but its odd

[upper hazel]

how i remember exists site where the project is added to the repository via a github link but there are several plugins in the github repository

[near furnace]

hey there im very sorry to bother you, but my brain is not braining right now. If you feel like doing it could you show me how i could do that?

[pseudo hazel]

if (args.length != 1) {
// your failed
return true;
}
// everything else

[near furnace]

thanks

do i use return true;?

or return false?

whats the difference tbh :)

[ivory sleet]

true

false is generally a no go

[near furnace]

sometimes false returns the command you executed idk why

[ivory sleet]

false sends the command sender an ugly message

so people tend to return true

[near furnace]

i see

[eternal oxide]

return false if you want it to show an error/usage for the command. return true if you want a clean exit

[pseudo hazel]

or return true if you already show your own error

[eternal oxide]

yup

[stuck oar]

anyoen know?

[eternal oxide]

what?

[pseudo hazel]

your plugin class implements commandexecutor?

[eternal oxide]

default JavaPlugin is already a CommandExecutor. IF the command is in your plugin.yml it will fire via JavaPlugin

so long as you add an override onCommand

[pseudo hazel]

oh nice I didnt know

[near furnace]

Whenever i set (args.length != 1) return true;, all the else if statements turn red

[pseudo hazel]

yes because your syntax is broke

[near furnace]

whats broken :(

[upper hazel]

what best module system?

[eternal oxide]

doing the same check three times means only the first ever runs

[pseudo hazel]

looks like a basic java syntax error

[upper hazel]

first version using build system

[pseudo hazel]

if () return whater; is already the whole statement and result, you cant use {} after that

[near furnace]

oh i see

[pseudo hazel]

thats why I never type if statements all on a single line

its just confusing

[quiet ice]

Assuming we are talking about maven/gradle multi-module builds, I personally prefer the first approach, but either one would be decent.

Although the second approach might be more difficult to represent as a maven project, if not straight-up impossible

[gleaming grove]

For me such structure working well project.api (interfaces) <- project
.core (impl) <- project.spigot

[stuck oar]

            Player p = (Player) sender;
            PlayerLevelManager playerLevelManager = this.levelManagerHashMap.get(p.getUniqueId());
            int level = playerLevelManager.getLevel();
            Double moneyneeded = getConfig().getDouble("levels." + level + ".moneyreq");

            if (playerLevelManager.getXp() >= getConfig().getInt("levels." + level + ".xpneeded")) {
                if (econ.getBalance(p) >= moneyneeded) {
                    econ.withdrawPlayer(p, moneyneeded);
                    p.sendMessage("§d§l(!) §dYou just leveled up from §d§nLevel " + playerLevelManager.getLevel() + " §d to §d§nLevel " + (playerLevelManager.getLevel() + 1));
                    playerLevelManager.setLevel(playerLevelManager.getLevel() + 1);
                    playerLevelManager.setXp(0);
                    setscore(p, playerLevelManager.getLevel(), playerLevelManager.getXp());
                } else {
                    p.sendMessage("§c§l(!) §cYou don't have enough §c§lMoney§c to §c§lLevel Up");
                    p.sendMessage("§c§l* §7Level up Cost: §7§n$" + moneyneeded);
                    p.sendMessage("§c§l* §7Your Balance: §7§n$" + econ.getBalance(p));
                }
            }

        }```

anyone know why this isnt doing anything the command runs but doesnt do anything all i did was add the ```playerLevelManager.setXp(0);```

[near furnace]

public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {

        Plugin plugin = myplugin.getPlugin();

        if (args.length == 0 || args.length < 0) {

            sender.sendMessage(ChatColor.translateAlternateColorCodes('&', "&c" + "Incomplete Syntax: Choose true or false"));
            return true;

        }

        if (args.length > 1) {

            sender.sendMessage(ChatColor.translateAlternateColorCodes('&', "&c" + "Invalid Syntax: Choose true or false"));
            return true;

        }

        if (args[0].equals("true")) {

            plugin.getConfig().set("feed-player", true);
            sender.sendMessage(ChatColor.GREEN + "Set the value to true");
            plugin.saveConfig();

        } else if (args[0].equals("false")) {

            plugin.getConfig().set("feed-player", false);
            sender.sendMessage(ChatColor.GREEN + "Set the value to false");
            plugin.saveConfig();

        } else {

            sender.sendMessage(ChatColor.translateAlternateColorCodes('&', "&c" + "Please select either true or false"));
            return true;

        }

        return true;

    }```

YIPPEEEE!!, Thanks Steaf and all the others for helping me! This code functions just the way I want it to :)

[tardy delta]

now realize ChatColor.translateAlternateColorCodes can be a utility function

[pseudo hazel]

using translatealternatecolorcodes on your hardcoded strings is beyond criminal

i didnt even notice before

just use the chatcolor constants

like you are doing for green funnily enough

[tardy delta]

use a string processor 🤓

[pseudo hazel]

nah write the string in a databse and then use an enum to get the hardcoded value anyways, but now from a database instead

[quaint mantle]

use mm :/

[tardy delta]

no

[stuck oar]

anyone know

[pseudo hazel]

maybe add some prints or something

so you can see where it gets stuck

[peak depot]

why even bother doing ChatColor translate in hardcoded messages if you can simply use §

[tardy delta]

cuz i dont have that thing on my keyboard ;-;

[peak depot]

what keyboard lang you got

[eternal oxide]

UK/EU don't have that character on a key

[peak depot]

I got German layout and shift + 3 is it

[eternal oxide]

£ is UK Shift + 3

its literally not on a UK keyboard

[tardy delta]

tbf idk

reminds me of one of those memes

[eternal oxide]

a Dvorak and QWERTZ key layout has it on Shift + 3

[peak depot]

Dvorak is the worst layout I ever saw

why did you make me google that

[eternal oxide]

oh no , its only QWERTZ

so German and Nordic

Hey does anyone know how to install the latest build of ProtocolLib so I can use their APIs?

All they provide is a jar file but there's no instruction on how to use this API in my code and load it into my spigot server

[peak depot]

use maven or gradle i suppose

[eternal oxide]

oh German, Nordic and Swedish. I don;t see it on any other key layout

[mild flume]

I tried adding it as a local maven dependency but I just got "plugin not found"

[peak depot]

https://github.com/dmulloy2/ProtocolLib

scroll the readme

[mild flume]

that's outdated for my version 1.20.6

[mild flume]

and just gives the same error

there is no repository after 5.1.0 sadly

although https://repo.dmulloy2.net/repository/public/ is down im wondering if it's literally just a server issue

[peak depot]

they got 5.2 in their releases on the github

[mild flume]

yeah that's what i mean here

you can't just change that version to your pom.xml afaik

like if you enter <version>5.2.0</version> is errors out

they only provide a jar file

but im unsure how you would link that to your project

because i tried it locally and it gave the same error weirdly

[peak depot]

5.1 also throws an error so prob server issues

[mild flume]

ah alr, ill wait out and hope that's the case 🤞

thanks

a lot of people when searching the issue just said to update it from 5.1.0

but weird they don't have a server for that

[peak depot]

Hey, I'm trying to make this system that serializes inventory as itemstack array in form of bytes to save it in database however there seems to be an EOFException happening and i have no idea what causes it.

My code: https://paste.md-5.net/otaxaronav.cs

[tardy delta]

no need to write bools

[wintry dagger]

What line?

[eternal oxide]

you are writing a bool only when its null, but on read you always read a bool

[tardy delta]

he always writes bools

[eternal oxide]

ah yeah I didn;t see that

[tardy delta]

i dont get the decodeItem() , just call is.readObj

dunno why youre creating a new input stream on the existing byte array

[quaint mantle]

ahhhh the wiki on serialization doesnt cover sql yet

:(((

anyone know any good tuts on serializing itemstackz to sql

[mossy flume]

theyre having an outage at the moment

[grim hound]

can you open a url for a player in a gui for example?

so not in a chat message

[tardy delta]

write them to a BukkitObjectOutputStream and optionally convert the byte array to base64

im wondering if that conversion would use more bytes or less

[quaint mantle]

interesting

[quaint mantle]

sick! any good tuts on that on the interwebs u know of?

[tardy delta]

paste site above ur head

[grim hound]

does anyone know?

[tardy delta]

just write the size of the inventory and all items to the stream

dont bother using booleans

[onyx fjord]

items[i] = item;

i believe

[onyx fjord]

ill have cases where i need to load a singular item

[tardy delta]

hmm?

[grim hound]

so it's not possible?

[peak depot]

no I think you cant force them only when they click on chat links / TextCompontents

[grim hound]

that's sad

thanks

[quaint mantle]

is storing vaults in yaml a dumb idea? like would that be excessively laggy?

[grim hound]

what is a vault?

[quaint mantle]

its just an inventory of items

[sullen wharf]

How to properly colorize note particles?

[quaint mantle]

but each player might have like 10

[peak depot]

prob least laggy if yaml then would be base64 encode the inv

[quaint mantle]

like base64 is least laggy?

[hot walrus]

Guys, not about this conversation, but is there a plugin + mod combo that allows sending client side code from the server to the client that the mod then runs to avoid latency?

[peak depot]

its just making it to a string witch stores all of the data and then you can decode it using spiot natives

[onyx fjord]

but how do i write a null item

if i dont save the null ones inventory slots are messed up

[tardy delta]

dataOut.writeObj(null)

[onyx fjord]

and inv must be a multiplir of 9

[peak depot]

I think therse a way bc therse a way to block eg LabyMod features using a plugin

but no clue how

[hot walrus]

Yeah but that just sends a couple of packets, not full code with a vm on client

But what im asking about is not like something widely known in the plugin community, right?

[smoky anchor]

Are you talking about arbitary code execution with code sent from the server to the client ?
Noone in their right mind would ever create that without ill intent or just plain stupidity.

[mild flume]

yeah just saw your reply to the issue haha

[quaint mantle]

are there any good tutorials anywhere on this? this sounds like what i want to do

[tardy delta]

i just told you what to do

[quaint mantle]

oh i thought you were talking to the other guy

xD

[onyx fjord]

doesnt writing null just write nothing

[tardy delta]

always worked for me, ig it just writes some placeholder

[onyx fjord]

ij tells me to write the itemstack, since it can be null anyway

so same thing

[wet breach]

how would this avoid latency?

[hot walrus]

If you send over code that does for example a cool particle animation, that code could run on the client for multiple seconds and no lag because particles arent send over to the client

[peak depot]

https://www.youtube.com/watch?v=xIl5v9Iyb08

[wet breach]

client still has to render said particles which can be achieved via a packet the same way

[quaint mantle]

🔥

[wet breach]

now that we know that a packet can achieve the same result, the question is back at, where did it avoid latency?

[hot walrus]

sending packets takes 50 - 100ms based on serverlocation, but running the code on client could render the particles next tick

[wet breach]

you still have to send the code via network

[hot walrus]

but you send that once

at server join

[onyx fjord]

okay i fixed the issue now

[wet breach]

I am guessing you have shitty internet and this is why it is an issue for you?

[onyx fjord]

most likely this line

whatever, it works, im happy, and no booleans 😄

[hot walrus]

no im just thinking about if you could make a gamemode with this on a server https://www.youtube.com/watch?v=r70xJytj0sw

[onyx fjord]

yall know how big an SQLITE blob is?

[quaint mantle]

LOL how big

[onyx fjord]

or can be*

no im asking how big it can be

[quaint mantle]

oh

xD

[hot walrus]

and if you can offload work to the client, less packets send + less processing server side = more fancy things you can do on servers

[wet breach]

with a mod sure, but not sure why RCE is needed for this o.O

[wet breach]

servers are not hurting via networking related stuff by any means

[smoky anchor]

It could be done without RCE, just send "animation files" instead of code.
But I know of no mod that does this

[hazy parrot]

1gb afaik

By default

[hot walrus]

So you only need one mod for all servers, and every server can add their own functionality

[wet breach]

this is what I was going to say

[wet breach]

seems you have no understanding in how servers work

[smoky anchor]

My guess is that this will become possible once we get custom entities with custom models.
But that can take anywhere from next monday snapshot to few years.
(in vanilla)

[hot walrus]

but can you do this with animation files? https://www.youtube.com/watch?v=r70xJytj0sw

[hot walrus]

wdym

[onyx fjord]

oh thats enough then

a single item is 1kb

[wet breach]

so you want to use RCE which is notorious for being a security risk however there is ways to use such things in a safe manner that wouldn't compromise someones system. But RCE so far isn't needed to achieve what you are wanting.

[onyx fjord]

but thats with nulls included

[wet breach]

your excuse for wanting the mod, is because "reduce network load" Which is not even an issue unless you just have a shitty system and internet and shitty hosting provider

then I could see networking being an issue for you

[hot walrus]

RCE is not insecure if you do it with a vm, limited api and a certificate system so only checked code is allowed

[hot walrus]

stfu

[wet breach]

I am not about to take security advice from a random on discord

[hot walrus]

no its about latency

[smoky anchor]

This much complexity is not needed even if you have this "security"

[wet breach]

yes shitty internet

[hot walrus]

the things shown would not be very smooth even with good internet

[wet breach]

and your proof of that is?

[quaint mantle]

thanks for linking me to that vid @peak depot 🫡

[hot walrus]

and what do you if a server is in location like japan

[wet breach]

because I have plenty of experience that says otherwise

and plenty of games

[hot walrus]

asked the guys who made the second demo

[wet breach]

most of your latency isssue is with rendering and not networking

[peak depot]

np

[wet breach]

also have to take into consideration that the vanilla client isn't super well made either

[hot walrus]

Also, with such a mod you can hotswap textures, you can technically implement some shader api for servers, you could do a lot

[wet breach]

you can do all that without RCE

[eternal night]

resource packs ✨

[wet breach]

there is a place for RCE but so far what you are wanting it for isn't a reason to use such things and would only compromise people's systems if anything else

[hot walrus]

why would it be unsafe if its based on a certificate system

[eternal night]

"certificate system"

[wet breach]

not sure what you are talking about certificate system?

[eternal night]

lemme just have mojang review this plugin

[peak depot]

nah for that you gotta need artis skills to much for a dev

[hot walrus]

no the dev the reviews this client pack and then adds a certificate the client checks for when receiving this code

[eternal night]

"the mod"

[hot walrus]

the dev

[wet breach]

the client adds a certificate to a mod the client is going to run?

[eternal night]

what dev??

[wet breach]

so....how does the client know its good?

[peak depot]

let bro dream

[hot walrus]

the mod dev

stfu

[eternal night]

so the mod dev needs to review every consumer of their mod API

every single version release

[hazy parrot]

Seems okay to me

[eternal night]

sounds easy

[wet breach]

evil is a necessity sometimes you know

[hot walrus]

for big servers, maybe, but even if you do it without certificates, theres safe way to make java scriptable and whats even stopping me from using lua, which is op for scripting

[eternal night]

what

"safe ways to make java scriptable" LOL

[hazy parrot]

You are trying to solve a problem which doesn't exist

[wet breach]

maybe they will make another javascript 🙂

[hot walrus]

yeah true

but i have ideas sometimes

[eternal night]

facts, scriptable java is just javascript

[hot walrus]

but you dont need to use java, just run lua an client

[hazy parrot]

Well I know java,I just need to learn the script part

[quaint mantle]

this entire conversation has gone completely over my head

[hot walrus]

cant blame you

[eternal night]

"just use lua"

[hot walrus]

tf is wrong with that then

[eternal night]

so now you also have to develop a minecraft modding api in lua

[wet breach]

we already have mods and plugins that allow you to use other languages if you want, however doing so adds latency which is what you were trying to reduce or remove, as the language now needs to be interpreted in order to interact with java

[hot walrus]

the thing is the api is not going to be big, as big apis are bad for security

[eternal night]

?

big apis are bad for security?

[wet breach]

oh no lynx your api is a security risk now

[hot walrus]

rather powerful apis

[eternal night]

yea damn, spigot-api is ded

[eternal night]

True, like APIs that allow sending lua code to run on clients

[onyx fjord]

❌

[hot walrus]

lua goes fast af bro

[onyx fjord]

paper shill detected

[peak depot]

you are programming for hypixel or why are you so hard concerned about security

[eternal night]

what does speed have to do with security

[onyx fjord]

😠

[wet breach]

people should always be concerned with security

[hot walrus]

guy before was concerned, but bitcoin mining on clients could otherwise happen

[wet breach]

to be fair, security does at times get in the way of speed. It is a known thing that if you want to be fast as possible you also have to do away with security

[eternal night]

Well yea, but that is a general vibe, not specific to lua

[wet breach]

but you know gaining that extra 1kb/s isn't necessarily worth it either

[rotund orchid]

what?

[hot walrus]

not the point, but if i cant imaging running something like this https://cdn.discordapp.com/attachments/1041278575145402448/1041278575380267008/mcvideo.mp4?ex=66c068be&is=66bf173e&hm=0eaa0bcfc90f811c03784aa159ce99620391c35e7f93ba43a49d4f57d8ba8808&
would be smooth for the client, or good for servers to process

[wet breach]

then you haven't experienced a decent server hardware it seems

or a decent pc

[eternal night]

I mean, the video of the spider you sent earlier is literally a spigot plugin

[wet breach]

maybe bad internet too

[wet breach]

shhhh

[hot walrus]

nope valence local server

rust goes brrrr

[wet breach]

I was wanting to see how long it would have gone on for before they noticed that XD

[eternal night]

???

https://www.youtube.com/watch?v=r70xJytj0sw

literally a spigot plugin

[hot walrus]

thats spigot yeah

but thats also locally

i dont think that would be nearly as cool on a server

[wet breach]

ok, lets take a minute to process that

so....the server is running on the pc and the client is also running on the pc, two things that are notorious in needing resources

and they even recorded it at the same time in HD

[hot walrus]

thats not resource intensive, but its bad with latency

[wet breach]

this is before any packets flying around the internet

packets are quicker then you think

[hot walrus]

how fast

[eternal oxide]

over 9000!

[wet breach]

as long as you have 100ms in average latency to the server you wouldn't notice any lag

[hot walrus]

Quick question, can you simulate latency on local server

[wet breach]

yes

[eternal night]

tc

[smoky anchor]

@hot walrus Try joining Wynncraft.
They got shitload of custom mobs with animations like this.
It does not lag in the latency meaning.
(Any lag you would see is most likely a server dying due to new update and many players)

[hot walrus]

Oh true

fair point

[smoky anchor]

🤦‍♂️

[wet breach]

I love they accepted your input without hesitating guess I should have just gave some random network name next time

[hot walrus]

To be fair, wynncraft guess was quite lucky

[wet breach]

not sure what that has to do with anything or why you believe I am interested in some random network

[hot walrus]

Ig what im asking for is a on server join modloader, with an api for the server

[near furnace]

is this a mod?

[eternal night]

no that is a spigot plugin

[near furnace]

i refuse to believe this is a plugin, it has super cool custom models

Does he use a resourcepack?

[pine crest]

probably

[eternal night]

might just be block displays with a transformation?

[pine crest]

or that

[near furnace]

so no resource pack?

[sly topaz]

200ms more than enough for minecraft, I play every day with that latency just fine

[eternal oxide]

whats equivalent to <scope>provided</scope> in gradle?

[blazing ocean]

Hey, I want to use this small library uploaded on https://jitpack.io.

[shadow night]

I thought it can be any number, just looping

it is 0 to 360, but the sun is odd

Don't quote me but if I remoeber it was messed up when they changed the sun direction

it used to

[tardy delta]

only read the "so notch changed it" when i hit enter

[eternal oxide]

Notch changed it and now its 90 degrees

it won't get deleted unless the git repo gets deleted

you can just make a fork and use the coordinates of your fork if you're concerned about that

Illegal char <"> at index 0: "C:\Users\domino\IdeaProjects\VoxelTeamsZ\target\VoxelTeamsZ-1.0.jar"

There is literally no illegal char

and that is not the path I'm using either

is intellij actually fucked?

[tawdry echo]

https://blog.jeff-media.com/manually-installing-jar-files-to-your-local-maven-repository/

[grim ice]

Yes

That answers about 0% of what I asked

im doing the bad way, sure

it is still a way, there's no reason for why It's screaming at the air

Ok, now it's doing this even after I removed the dependency

I love Intellij.

[eternal oxide]

it loves its broken caches

[grim ice]

I invalidated caches and restarted multiple times, still is broken

bro...

[eternal oxide]

Have to reinstall OS then 🙂

[grim ice]

lmao

OK so

I can legit

have an empty pom.xml

and it would still do this

[near furnace]

Is it possible to choose the order of the tab completion, like i wanna show true first then false? But in game it shows false first

do i use array? and add the array to the arraylist

[blazing ocean]

[grim ice]

im legit using the paid version

[eternal oxide]

You can't. Client will display alphabetically

[grim ice]

although for free since im a student

but if i paid $100 for this

I'd kms

um what?

it costs $600?

LOL

THIS SHIT COSTS 600???

[eternal oxide]

per year

[eternal night]

that is also the company plan

not the personal one

[grim ice]

oh true

it costs $170

for the individual plan

[eternal night]

in the first year

[young knoll]

Hey it gets cheaper in later years!

[grim ice]

which is still ridiculous

[young knoll]

Which is kinda weird

[eternal night]

if you were a student, you can insta skip the first two years iirc

[eternal oxide]

you can super charge it for an additional $200

[young knoll]

Normally it’s the opposite

[eternal night]

what

[remote swallow]

basically

[young knoll]

Well for domains at least

[eternal night]

oh xD

[remote swallow]

you buy the more expensive ones then you cant ever leave because if you come back it means you have to pay it again

[eternal night]

I mean most subscriptions reward staying with them for long

[young knoll]

They offer you like 99¢ the first year and then $20 after

[eternal night]

Yea because domains you cannot really afford to loose xD

[grim ice]

I can compile with maven

but intellij

cries about literally nothing

wth dude

this is taking too long

LOOOL

THE COMMUNITY EDITION WORKS

THATS RIDICULOUS BRO

[near furnace]

i see, so not possible. Only way to do that would be intercept packets and change them or make a mod changing the game code lul

[shadow night]

I even have a method for that somewhere in my Util class

[young knoll]

StringUtil.copyPartialMatches

[glass inlet]

How to prevent LivingEntity from colliding with a player? The LivingEntity.setCollidable(false) doesn't work for me.

[chrome beacon]

You need to use teams

[shadow night]

imagine if we had mixins...

[glass inlet]

team.setOption(Team.Option.COLLISION_RULE, Team.OptionStatus.NEVER);

Yeah did that

[chrome beacon]

Can't mixin the client from the server

[shadow night]

ah it's a client thing?

[chrome beacon]

Show your code

Yes

That entity isn't colliding with the player

It's the other way around now

And is controlled by client as all player movement is

[glass inlet]

public void setNoCollision(Player player) {
    Scoreboard scoreboard = player.getScoreboard();
    String teamName = "noCollide_" + player.getName();
    Team team = scoreboard.getTeam(teamName);
    if (team == null) {
        team = scoreboard.registerNewTeam(teamName);
        team.setOption(Team.Option.COLLISION_RULE, Team.OptionStatus.NEVER);
    }
    team.addEntry(player.getName());
}

[chrome beacon]

You're never adding the other entity to the team

[grim hound]

I uh

would need some help with images

I'm trying to render an image bigger than 128x128

on 4 maps

and uh

and I'm not sure what I'm doing wrong

https://paste.md-5.net/elavisowuy.java tis the code

[paper viper]

You checked if the buffered image split works correctly right

When you get the sub images

Also don’t name your class Main

[grim hound]

how else would you want to name a main class?

[grim hound]

yeah

[grim hound]

I replaced Location::add with Location::subtract

and somehow everything works now

I have no idea why

[paper viper]

Read my guide

[grim hound]

but I'm just gonna leave it at that

[paper viper]

?main

[undone axle]

https://www.spigotmc.org/threads/why-you-shouldnt-name-your-main-plugin-class-main.493289/

[grim hound]

I didn't pick up the name from anything

One big origin comes from those many horrible Spigot plugin tutorials on Youtube, where they do not explain anything and force new people to copy and paste code

[grim hound]

I learned java from one guy

and got the naming from him

[paper viper]

Ok I don’t care just don’t do it

Anyways

[grim hound]

that is so stupid

[paper viper]

Give me a second

[grim hound]

"Oh no, don't dooo itttt"

"It'll give you nightmaressss"

"And I said so"

[paper viper]

Idc, change it or not

Your choice

[grim hound]

what

is this nonsense

I swear some people are just real life twitter

just spread misinformation instead of cancelling people

it is, just for this particular framework

why would somebody think that?

[quaint mantle]

how are we spigot gang

[grim hound]

good

ain't nobody gonna be using my class

I have another main class that's of a different name

I use Main in the spigot boostrap because the name is short and perfect for debugging

[grim hound]

while if I tried to type this, then damn, would many Bukkit- classes be suggested

[paper viper]

It was just a suggestion but fine

You can choose what you want to do

[grim hound]

I'm explaining my reasoning

[grim hound]

and why I think that this doesn't bear much sense

[paper viper]

And I don’t care because many people do and I don’t wanna argue abt it the thousandth time

[earnest girder]

if I have a Vector that I want to apply to a player's launched projectile's direction (I want it to add a horizontal and vertical "recoil" to the projectile), how would I do that?

[grim hound]

like we ain't arguing about including underscores in class names

[grim hound]

this stuff straight up illegal

[grim hound]

depends

[paper viper]

Ok 👍🏻

[grim hound]

I love you brother

[quaint mantle]

does anyone know good a good tutorial on use of .class in java?

[grim hound]

🤝

[quaint mantle]

im trying to expand my tiny brian

[grim hound]

usually listen to ProjectileLaunchEvent and just Entity::setVelocity

[grim hound]

uh

.class is a compiled .java file

I think

[quaint mantle]

truer but like you know in code how sometimes there are references to class objects like ItemStack.class

or whatevers

[grim hound]

that references the Class<T> object

[quaint mantle]

oh okay

whats that called

[grim hound]

so Class<ItemStack> clazz = ItemStack.class

[quaint mantle]

dang interesting

[grim hound]

the T?

[quaint mantle]

ye!

[earnest girder]

right but how do I add a vector to the projectile's velocity? and how do I make it relative to the direction the player is facing, not the X, Y, and Z axis

[grim hound]

generic type

[quaint mantle]

dang okay ill goggle this

thanks!

[earnest girder]

do I use vector multiply or vector add or something else?

[grim hound]

Entity::getVelocity
Vector::add
Entity::setVelocity

[grim hound]

np 👍

[grim hound]

yeah that just

messed up the QR code

it's now invalid

xD

damn

wait no

it was background noise that made it invalid

[covert ember]

Hello, a friend of mine made this Plugin called "Commandbinder". There youcan bind Commands on a certain item. It's still pretty buggy and there are placeholders that should work but don't. The one I'd need is "%lookingAt%. It displays the coordinates of a block, that the player's looking at, that's not air, but it doesn't work. I have almost no idea how to code, sadly, so I'm asking you, to maybe tell me what the problem is.

      if (cmd.contains("%lookingAt%") && this.p.getEyeLocation().getBlock().getType() != Material.AIR) {
         Location loc = this.p.getTargetBlock((Set)null, 128).getLocation();
         cmd = cmd.replace("%lookingAt%", loc.getX() + " " + loc.getY() + " " + loc.getZ());
      }

[young knoll]

Why would you check if the block on the players eye location is not air

Unless they are suffocating in a wall it should always be air (or a liquid)

[covert ember]

Yes, but I need it to detect for example if you want to break a tree, you're looking at a log, I need exactly that, that it would display the coordinates of the log

[young knoll]

Then remove the air check and just use the getTargetBlock

[covert ember]

Wouldn't it be just air then?

[young knoll]

No

It looks for the first solid block the player is looking

Within range

[covert ember]

Ah okay thanks

[earnest girder]

how do servers have scoreboards without the red line numbers?

https://imgur.com/a/kXMDfH5

[young knoll]

It’s a new feature in 1.20.5 (iirc)

In older versions you could use shaders

[earnest girder]

what is the feature?

[young knoll]

It’s like objective number format or something

I don’t think the api pr for it ever got merged

[earnest girder]

so it isn't possible with spigot?

[young knoll]

Not without NMS

[earnest girder]

how can it be done with NMS?

I cant find anything online. everything just says it isnt possible

[young knoll]

Uhh

@worldly ingot you wrote the PR :)

[slender elbow]

it sure is possible

vanilla does it lol

[pseudo hazel]

I think paper also has it xD

[earnest girder]

is paper a different API?

like if Ive been coding a spigot plugin would switching to paper be a pain in the ass

or is it the same code?

[slender elbow]

it's a fork of spigot, meaning it has the same APIs and more

but if you use paper api in your plugin, it will not work on a spigot server

[earnest girder]

will I have to change anything in my code when I switch over?

if I plan on completely switching to paper?

[carmine mica]

there are a few methods which have been changed, but nothing significant

generally the only methods which are API-incompatible are ones where Paper had a method named smth, and spigot later added a method that did smth else with a conflicting signature

there are lots of deprecations Paper adds for broken/outdated/legacy functionality that suggests alternatives to use

but the deprecated methods usually function the same as before

[wraith delta]

even if your server runs paper, its better to use spigot api, unless there is a very specific method you need that only paper has.

[dark jolt]

Whats the best way to write a file

[wraith delta]

Depends on what you are writing. what do you plan to save/read?

[dark jolt]

So im making a audio client plugin that when you do /createregion <wgname> <audioname>

That it would in the yaml file fill out underneath the Regions:
It will read and write it

Regions:
Epcot:
main.mp3

[wraith delta]

such audio info, is that just a string you need saved?

[dark jolt]

Yea so they would do that command then it would write in a config file called regionlist and then a listener would read that config file for all the regions to see if a player is in a region then play the audio through a websocket

[wraith delta]

Well then to save it like that you can do it with yaml, the line to write that is dataConfig.set("Regions." + region, name);

public String getName(String region) {
  return dataConfig.getString("Regions." + region);
}
```then grab it like this i believe

[dark jolt]

Is that just the reading part it seems?

[wraith delta]

which parts do you need? do you know how to have a custom config?

[dark jolt]

Yea I have that made already

[wraith delta]

ok ill write a little bigger example of just the set and get one sec

    public void saveDataConfig() {
        try {
            dataConfig.save(dataConfigFile);
        } catch (IOException e) { }
    }
    
    public void setRegionInfo(String region, String filename) {
        dataConfig.set("Regions." + region + ".filename", filename);
        saveDataConfig();
    }
    
    public String getRegionInfo(String region) {
        return dataConfig.getString("Regions." + region + ".filename");
    }

[dark jolt]

Ah alr

Easy enough

[wraith delta]

Right. String something = MainClass...getRegionInfo(region); then something like this would be used elsewhere you have the region name to request with

[dark jolt]

Ok

Thank you

[quaint mantle]

if (!event.getAddress().getHostAddress().equals(event.getRealAddress().getHostAddress())){} would something like this work in playerlogin event

[river oracle]

what are you checking for?

[quaint mantle]

to see if its a vpn

[river oracle]

lol yeah no that's not how that works

[quaint mantle]

yeah just making sure

cuz idrk what getrealaddres means

[river oracle]

found a forums post

Spigot spoofs the IP address when running under bungeecord mode; getAddress() should return the spoofed address (e.g. the clients IP address) if one has been set, while getRealAddress() in those instances should return the IP of the bungeecord instance

[quaint mantle]

ohh

if they arent using a spoofed ip would itstill work

for getrealadderess

[river oracle]

as far as blocking VPNs I thnk the best way to do that is dig up some way to find which IPs are associated with a specific service

you might need to pay for that

[quaint mantle]

no ik, im just asking to see if they was an easier way

[river oracle]

not really

[quaint mantle]

cuz i saw that while looking through playerlogineventr

[river oracle]

the client wouldn't know your real IP anyways if you were under a VPN

it would only know the VPN IP

[quaint mantle]

^

[river oracle]

blocking VPNs is fairly hard

I'd say damn near impossible to be completely honest

[quaint mantle]

hey

[viscid carbon]

Hey @river oracle, Should i have stuff like setHome() in Playerdata or should i be doing all of this in playerDataManager?

and in playerData i should make methods like java public void setConfigurationSection(String name) { this.getFileHandler().getConfig().createSection(name); }
instead of calling the fileHandler

[river oracle]

idk if this is completely "ideal" but usually I'll have a setup like

public interface StorageHandle {
  // usually I abstract this for different databases and such but you really don't have to
}

public class PlayerData {
  public void save(StorageHandle handle)

  public static void load(UUID uuid, StorageHandle handle)
}

[viscid carbon]

Currently im doing it like this, and i dont feel like its the correct way. yK?

    public void setPlayerRank(String rank) {
        this.playerRank = rank;
        getFileHandler().getConfig().set("Settings.Rank", rank);
    }

    public void setHome(String name, Location location) {
        getFileHandler().getConfig().set(String.format("Homes.%s", name), location);
    }```

[river oracle]

I mean its not horrible, but at the same time its not great

Personally I think this structure is only fine because you're using configs

if this were a database or any other file type I'd say this structure would be unacceptable

however, because Configs are 100% in memory doing stuff like this really isn't an issue

[echo tangle]

thinking of making a website & plugin where, for example, clicking a button on the website runs a command in the game. what would be the best approach towards this? websockets with something like jetty?

[river oracle]

don't even need WebSockets if you're on the same server you could just use regular Sockets

really any communication protocol will work as long as youre comfortable with it

[viscid carbon]

Okay i see, so doing it the way im doing it is called structure.

[river oracle]

what no?

[echo tangle]

oh alright, i'm not very used to using sockets

[viscid carbon]

But would it be better if i just did something like

public void set(String path, String value) {
fileHandler().getConfig.set(path, value);
}```
instead of making multiple things to set?

[river oracle]

I mean an abstraction like that is one way to go about things but if you're saving using 1 method I'd honestly go for the methods I stated above

I doubt everyone would agree with such design, but to me its most clean and keeps saving and loading logic in one place

you could even dump the StorageHandler and just use whatever FileHandler you're using

there is no reason to make abstractions at that level unless you're planning to support like 5 different databases

[viscid carbon]

Yeah, i dont plan on that unless needed but YML files arent that big. it would be if there was 1k+ players but databases sound out of my reach atm lol.

[river oracle]

honestly for you my reccomendation
Detach the FileHandler object from the player and instead use it in save and load methods. That way each PlayerData object is blissfully unaware of its FileHandler, but when the server stops or the player leaves you can get then and run the according save method

that way if you ever add a database like SQLite it'll be much less time to add it in than if you were to do that now

[viscid carbon]

Okay, thank you for that and your time with teaching a newbie

❤️

[river oracle]

NP I was a newbie myself not to long ago

[viscid carbon]

I just dont wanna base everything off it again and it all be wrong like the first plugin xD

[river oracle]

I still have one of my first plugins
https://github.com/Y2Kwastaken/SimpleHoes

[echo tangle]

wait so what would be the recommended way to do this if i wasnt hosting the website on the server.

[river oracle]

probably Websockets

but you need to be careful

make sure there is proper auth in place

[viscid carbon]

public static void cSend(CommandSender sender, String string) {
sender.sendMessage(clr(string));
}```

is this just a newbie thing to do?

xD

[wicked sinew]

Everything reminds me of her

[river oracle]

meh I dislike such a pattern

but its personal opinion

[wicked sinew]

eh, sometimes a quick utility function is nice

[viscid carbon]

Ik, its in your SimpleHoes xD you said ew

[river oracle]

My opinion have changed a lot in 3 years I guess

[echo tangle]

ohh, so would having them on the same server be better due to privacy reasons?

[viscid carbon]

A programmer is constantly changing the way they do stuff, a once wise one once told me 😉

[river oracle]

not if you make good authentication

[echo tangle]

i doubt i will

[river oracle]

I mean there are libraries and also payed services

to ensure your auth is great

wrong reply

[river oracle]

Well honestly if you don't look at the code you wrote even a few weeks ago and think man I could improve this you've started to plateau

[viscid carbon]

I do it after a day xD

[river oracle]

if you look at the code you wrote 1 year ago and don't go what the fuck is this mess you are trash 💪 🔥 💯

[viscid carbon]

i could make you throw up if you want xD

[river oracle]

I have a compiled jar of my oldest project ever still

it can't be much worse than that

[echo tangle]

something like jetty?

[viscid carbon]

https://github.com/MrArcane/CrispyCore

Idk take a gander

xD

[river oracle]

the out and .idea folders

great start

did you quit coding?

[viscid carbon]

Everything is static

life got busy

[river oracle]

makes sense

I started coding in 2020 I rage quit for nearly a year and a half with java

I'd code for a few weeks and go I fucking hate this why do I keep doing this

then come back after a few months

[viscid carbon]

never learned properly though, i had someone that knew a lot and he thought me the basics and then somebody that was in uni but he would just spoon feed certain problems. I made this plugin for his server.

[viscid carbon]

Coding is addicting 🤷‍♂️

[river oracle]

I had a mentor too

he did not abandon me 🙏 and was good

the one person I follow on github kekw

I'm better than him in java, but he's got my beat in pretty much every other department

[viscid carbon]

Lol these stories are nice to hear coming from somebody experienced. He never really abandoned me he kinda just got bored with java/minecraft and started learning py and other things lol

[river oracle]

first thing I ever wrote was AHK

idk if you've ever heard of that

[urban escarp]

Hello, im sorr but why event doesn't ececute when i eat food

[humble tulip]

Did you register your listener?

And what event are you listening to?

[urban escarp]

@EventHandler
    public void onEat(PlayerItemConsumeEvent e) {
        Player p = e.getPlayer();
        Material food = p.getInventory().getItemInMainHand().getType();
        p.sendMessage("§8(§c!§8)§7Tavoevent");

i cant get debug message

not sure if its right event anymore

[viscid carbon]

Wasnt that auto hot key or something?

[viscid carbon]

its not doing anything?

make sure you're registering it in your main class

[urban escarp]

it just didn't compile somehow lmao, sorrry

[viscid carbon]

xD

okay

[fading beacon]

is there any event that listens for lighting levels when spawning hostile mobs?

[humble tulip]

You might be able to listen to entity spawn even and check the light level of the block where it's being spawned

[tawdry stone]

Is there a way to fade out a sound with a plugin (or mod)?

[echo basalt]

You could play it with an emitter entity and move it around

[echo basalt]

Is your listener registered

[torn shuttle]

or make a custom sound with a resource pack that fades natively

[echo basalt]

That can also work

Keep in mind sounds have to be in mono to have attenuation

[tawdry stone]

how can i make that?

[torn shuttle]

yell hard at your mic, then fade to a softer voice, convert the audio file to ogg then put it into a valid resource pack format and call it using the normal play sound methods (or even commands, minecraft is even nice enough to autosuggest custom sound files from your resource pack)

[tawdry stone]

oh, but what i'm trying to make is ambient music, like, play a sound (obviously a song) and when needed, fade it out

[wraith delta]

Q: Is it better to generate a new yaml file for each player uuid to save their data in. or is it better to make one data file and store each player in that one file with their data? yaml config

the concern is if one file would lag searching for the tree of data, but would it actually?

[summer scroll]

It's better to have one yaml file each player, but if the data is small then it doesn't matter for me at least.

[wraith delta]

maybe so. so in one file there would for example be 10k player uuid list and under each stores a few ints

but, the other method would be to have 10k yaml files that were generated and each stores those ints

this is to store crate key amounts

[summer scroll]

Personally I would just go for one file, just don't save/load the file everytime there are some changes.

Just save and load on server stop and server start.

[wraith delta]

if you dont save it, how would you read the updated int

[summer scroll]

You create like a hashmap to store the user data, basically like caching it.

You do the update there and only save on server stop

If you want to make the map size smaller, consider saving and loading on player quit and player join

[wraith delta]

but they can earn keys from gameplay

[summer scroll]

Yes, create User object that stores the keys data for each player

[wraith delta]

possibly

just seems concerning for if the player client crashes or server crashes that it may not save

[summer scroll]

You can create an auto-save system every 5 minutes or so.
