[mortal hare]

this feels so cursed

[wet breach]

right, that means remove the argument from there

since its not required lol

[waxen hound]

you should make another static function that constructs the object or use JavaPlugin.getPlugin instead of taking it as an argument

[timid hedge]

if you mean from getConfigFIle i have removed them
public static FileManager getConfigFile(){ if (instance == null){ instance = new FileManager(); } return instance; }

and i have the error

[waxen hound]

the second is a lazy singleton pattern but i’m not sure if u can use it before the plugin is enabled

[wet breach]

the api provides both a static and non static method to get the plugin instance 😉

[kindred valley]

man stop static abusing 👺

[waxen hound]

ah i see

i’ll stop interfering 😅

[kindred valley]

Static is very dangeous and can cause various problems just use it in your main method okey 👍🏿

[wet breach]

import java.io.File;
import java.io.IOException;

public class FileManager {
    
    private static Main plugin = Main.getInstance();

    private static FileManager instance;

    public void createConfigFile(String fileName){
        File file = new File(plugin.getDataFolder(), fileName);

        if (!file.exists()){
            try {
                file.createNewFile();
            }catch (IOException e){
                e.printStackTrace();
            }
        }
    }

    public void loadConfigFile(String fileName){
        File file = new File(plugin.getDataFolder(), fileName);

        if (!file.exists()){
            try {
                file.createNewFile();
            }catch (IOException e){
                e.printStackTrace();
            }
        }
    }

    public static FileManager getConfigFile(){
        if (instance == null){
            instance = new FileManager();
        }
        return instance;
    }
}

public class Main extends JavaPlugin {

   private static Main instance;

    private FileManager fileManager;

    @Override
    public void onEnable() {
        instance = this;
        fileManager = FileManager.getConfigFile();
        fileManager.createConfigFile("config.yml");
    }

    @Override
    public void onDisable() {
    }
    public static Main getInstance() {
        return instance;
    }
}

@timid hedge

fixed it for you

[waxen hound]

what problems specifically

[wet breach]

oh right, I see the problem you were having

[kindred valley]

you can go in prison

[wet breach]

give me a second to fix it lmao

[waxen hound]

oh, it’s probably a good idea to not use static then 😁

[hollow falcon]

#general Is anyone a mod of this discord server?

[worthy yarrow]

Static calls and methods are perfectly fine so long as you know how to use them

[timid hedge]

i still have the errror here
instance = new FileManager();

and i need
` public final Main plugin;

public FileManager(Main plugin){
    this.plugin = plugin;
}`

for
File file = new File(plugin.getDataFolder(), fileName);

[wet breach]

yeah give me a second

I am fixing it 😛

[timid hedge]

alr mb i didnt see your first message

[wet breach]

ok I updated it above

maybe you will notice the changes, however I will note that you shouldn't rely too much on static or abuse it, but for these purposes its perfectly fine

[timid hedge]

i still have the error here tho..
instance = new FileManager();

[wet breach]

you shouldn't have an error there o.O

oh I see

nvm yeah you shouldn't have an error there

[alpine solar]

why uhh

[timid hedge]

Why is is static abuse so bad tho?

[wet breach]

first, anything static does not get Garbaged collected once created (GC'ed) and second static can not be changed

[timid hedge]

if i remove Main plugin from here
public FileManager(){ this.plugin = plugin; }
It works fine now

[wet breach]

well what I showed above doesn't contain this

so yeah you shouldn't have that

If you can't get rid of stuff you can not free up memory so you should be careful in what you decide to be static. There is some objects that are inherently static for example your main plugin class is static because if it that class/object goes away so does the rest of your plugin effectively being unloaded. So main plugin class is fine to reference as static. Second, because static does not change this means it loses on being dynamic and thus will always reference the same stuff and not change.

[timid hedge]

or wait mb i didnt see that

[wet breach]

Over time hopefully you learn from this to make your stuff better 🙂

but small steps first I suppose, this is just the beginning to making what you are wanting and I will say its hardly from being the best, but just remember it does not always need to be best as long as it works 😉

[timid hedge]

idk if this is a dumb questin but what was this exactly used for?`
public static FileManager getConfigFile(){
if (instance == null){
instance = new FileManager();
}
return instance;
}

Because it checks if FIleManager is null and it if it is it creates a new filemanager? (or am i completly wrong)?
because i need a method to get the config path

[wet breach]

FileManager being the class/object. If it has not been initialized before, it will be null and if it is null it creates the object. If it is not null, it skips to the bottom and returns the instance that already exists. This is part of Singleton's and ensures only a single instance of that class exists in memory

Also, this allows the class to be GC'ed if it isn't being used and not worry about getting Nullpointer exceptions when referencing the class as that method takes care of loading 😄

[timid hedge]

gc meaning?

[wet breach]

garbage collected. Java's way of removing stuff in memory not being used to free up memory

[alpine solar]

why are you checking if instance is null

[wet breach]

because it will be null if the class is not loaded

[alpine solar]

Ah

[wet breach]

I suppose I should clarify how it works and why it is important to have instance at the top in that class

[timid hedge]

Is this completly wrong for getting the value from a config file?
public File getConfig(String fileName, String value){ return new File(plugin.getDataFolder(), fileName); }

File config = FileManager.initConfig().getConfig("config.yml", "a"); player.sendMessage(String.valueOf(config));

[wet breach]

So the purpose of a singleton class is to not have the ability to be initialized by normal means. Hence this class has no constructor. You could also use a private constructor (lazy loading). In this case we just have no constructor so you can't simply call new FileManager() outside of the class since its constructor is effectively private (in java no constructor is kind of the same as private but more protected since its not actually there on the surface with private on it). Anyways, since the class is not supposed to be initialized by normal means we can use an unassigned instance variable at the top, which makes it null and prevents our method at the bottom from throwing a nullpointer exception since the variable exists at the top just empty (null). The method at the bottom then takes care of assigning a value to it so now it is no longer null, until the class goes away and gets re-initialized and the process starts again.

[alpine solar]

lazy loading

that's so me

[wet breach]

lol

[wet breach]

(getData() here references YamlConfiguration which your filemanager class ideally should have)

String something = FileManager.getInstance.getData().getString("a");

import java.io.File;
import java.io.IOException;
import org.bukkit.configuration.ConfigurationSection;
import org.bukkit.configuration.file.YamlConfiguration;

public class FileManager {
    private File file;
    private YamlConfiguration data;
    private static Main plugin = Main.getInstance();

    private static FileManager instance;

    public void createConfigFile(String fileName){
        file = new File(plugin.getDataFolder(), fileName);

        if (!file.exists()){
            try {
                file.createNewFile();
            }catch (IOException e){
                e.printStackTrace();
            }
        }
    
    }

    public void loadConfigFile(String fileName){
        file = new File(plugin.getDataFolder(), fileName);

        if (!file.exists()){
            try {
                file.createNewFile();
            }catch (IOException e){
                e.printStackTrace();
            }
        }
    data = YamlConfiguration.loadConfiguration(file);
    }

    public YamlConfiguration getData() {
        return this.data;
    }

    

    public static FileManager getConfigFile(){
        if (instance == null){
            instance = new FileManager();
        }
        return instance;
    }
}

[ivory sleet]

Hows it so dangerous 🤔

[wet breach]

there we go @timid hedge added more to your filemanager class 🙂

placed the getData() method so now you can use it to pull yaml related stuff from a file you load 😉

however, this is not an ideal setup because at the moment you need to ensure you call loadConfigFile() first before you call getData()

otherwise you end up with nullpointers 😛

[alpine solar]

health problems

[ivory sleet]

Sounds severe

[alpine solar]

very

[ivory sleet]

I use static so much i was scared id be half a man after reading that statement

[wet breach]

one would say its better then a quarter of one

[ivory sleet]

Lol yea

[timid hedge]

but at the moment i cant only get files right? i need to add the path i want to pull out

[ivory sleet]

Icl you definitely have shot urself in the foot a couple of times when you need to use powermocks to unit test ur application

[wet breach]

if you want to use paths that is easy enough and you would just use the paths in the yaml file you have loaded in that string

String something = FileManager.getInstance.getData().getString("a");
String something = FileManager.getInstance.getData().getString("path.to.a");

but yeah you would need to ensure you load the appropriate yaml file first before using getData()

[rotund ravine]

Ew static

[wet breach]

indeed, I was about to make a comment in how this slowly shows how using static may not always be best but good news is that you can use this singleton class to initialize appropriate objects which I am hoping they progress to learn to do instead 🙂

[timid hedge]

ohh wait yeah i forgot that "path.to.a" existed...

idk how else im going to call loadconfigfile before getdata else than this
public YamlConfiguration getData() { if (data == null){ loadConfigFile(file.getName()); } return this.data; }

idk how im going to do it, so that is just my best guess for now...

[kindred valley]

youll end up in prison

ais

[wet breach]

maybe you should provide some of your wisdom 😛

[wet breach]

simply calling the method is sufficient

in another class you would do, loadConfigFile() somewhere in the top, then below that in the class you can do getData()

it doesn't have to occur in the same class lol

[ivory sleet]

Wonder how many developers would go to prison if that were the case

[kindred valley]

many

my father in jail for using that word in main method

[ivory sleet]

Good thing static isnt so dangerous then truth be told

[rotund ravine]

I did for a few years now i only do whenever i feel like it 👌🏻👌🏻

[thorn isle]

tan juck

[ivory sleet]

i thought jan tuck only wrote in kotlin

[timid hedge]

so like this?
` @Override
public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
if (!(sender instanceof Player)){
return false;
}
FileManager.instance.loadConfigFile("config.yml");

    Player player = (Player) sender;

    player.setHealth(0);


    String my_message = FileManager.instance.getData().getString("test path");
    player.sendMessage(my_message);


    return false;
}

}
`

I just want to know where FileManager.instance.loadConfigFile("config.yml"); should be placed

[waxen hound]

can you use three ticks when u wrap

```

[wet breach]

they probably didn't know that

[thorn isle]

off with their heads

[waxen hound]

i didnt mean anythig by it mb 😭

its just easier to read

[wet breach]

ideally you would just place it before you need to extract data from a particular yaml file

the way you have it above is acceptable and works

[thorn isle]

disk io on main thread is grounds for capital punishment

[wet breach]

now to teach you what was said earlier in regards to discord

if you use three back ticks " ` " and then put java you can create a code block that is styled

oops t hat didn't work

[thorn isle]

escape it with \ i think

```
java
```

[wet breach]

hmm seems I forgotten how to escape with discord

[waxen hound]

```java
test
```

[thorn isle]

myeah

\`

[wet breach]

perfect
@timid hedge

what turtle did, and then place everything below the java part/your code and it will make a single code block and style it in java format

[timid hedge]

alr thx

[eternal oxide]

?codeblock

[undone axle]

You can use the discord code block format to display code or just text in a more pleasing way:
```java
public class MyPlugin extends JavaPlugin {
@Override
public void onEnable() {

}

}```
Becomes:

public class MyPlugin extends JavaPlugin {
    @Override
    public void onEnable() {

    }
}```

[waxen hound]

does anyone have working code to send a entity metadata packet with protocollib

mine doesnt work

    private void updatePlayerLine(Player ply, Entity entity) {
        if(entity == null) {
            return;
        }

        PacketContainer packet = ProtocolLibrary.getProtocolManager()
                .createPacket(PacketType.Play.Server.ENTITY_METADATA);
        StructureModifier<List<WrappedDataValue>> watchableAccessor = packet.getDataValueCollectionModifier();

        packet.getIntegers().write(0, entity.getEntityId());

        final WrappedDataWatcher.Serializer chatSerializer = WrappedDataWatcher.Registry.getChatComponentSerializer(true);
        Component component = this.generateLine(ply, entity);
        String json = GsonComponentSerializer.gson().serialize(component);

        watchableAccessor.write(0, List.of(new WrappedDataValue(2, chatSerializer, Optional.of(WrappedChatComponent.fromJson(json)))));
        ProtocolLibrary.getProtocolManager().sendServerPacket(ply, packet);
    }

[timid hedge]

IS this the best way to make a config tho?

[wet breach]

no it is not

I believe I said that earlier

[timid hedge]

oh...

because i just want to make something that is good so i can keep using it without having to remake a config every time

[wet breach]

however, it works though and is easy enough to use for someone still learning. There is far better ways to do this, but some of those better ways require more understanding of java

as I said I am not fond at just giving someone the answers and would rather they learn and understand what it is they are making and using otherwise when you do encounter those better ways you will better know how it works as well as when you encounter problems understand what that problem is and fix it.

you can just easily google around for code and just copy paste it all day long if that is what you truly want but that doesn't guarantee you understanding it or know how it works

[timid hedge]

yea i understand that, but the thing i dont understand is just it dosent create a folder with my config file...

[wet breach]

ah you want to create a directory

well just like you can have paths when calling data in yaml when you specify the config file you can make paths with that too

and the method should create the directories and file at the same time

[timid hedge]

oh wait i forgot, i havent made anything that can add things to the config.yml

[timid hedge]

do you talk about this one

    public void createConfigFile(String fileName){
        file = new File(plugin.getDataFolder(), fileName);

        if (!file.exists()){
            try {
                file.createNewFile();
            }catch (IOException e){
                e.printStackTrace();
            }
        }
    }```

or this one

public void loadConfigFile(String fileName){
    file = new File(plugin.getDataFolder(), fileName);

    if (!file.exists()){
        try {
            file.createNewFile();
        }catch (IOException e){
            e.printStackTrace();
        }
    }
    data = YamlConfiguration.loadConfiguration(file);
}```

[wet breach]

well there both essentially the same, but we will stick with the current one which is the second one lol

so where it has fileName

[thorn isle]

always remember to print the message along with the exception's stack trace

[wet breach]

your variable in the method constructor would be this "file/path/file"

[thorn isle]

without the exception message, things can be very hard to nail down

[timid hedge]

should i just delete createconfigfile and use laodconfigfile instead? because data = YamlConfiguration.loadConfiguration(file); this line dosent do anything right now?

[wet breach]

well data does do something as it is used for getData();

technically could remove it, and just do YamlConfiguration.loadConfiguration(file); elsewhere if you really wanted to

[timid hedge]

but isnt that line only for that method??

[wet breach]

yeah, as I said you could remove it change it to your liking etc

you don't have to strictly do things as I say, just what I say are examples

[timid hedge]

yea i just misunderstood what you said beofre

[timid hedge]

wdym? where do i set that location

[wet breach]

it would be what you supply into fileName

it is a string after all

it is very interesting though that no one else is providing input 🤔

normally many people end up doing so, kind of a first that has not happened yet

[timid hedge]

i dont really understand, its in onEnable right?

    @Override
    public void onEnable() {
        instance = this;
        fileManager = FileManager.initConfig();
        fileManager.ymlFile("config.yml");
        getCommand("suicide").setExecutor(new SuicideCommand());
    }```

sorry if im too bad for this...

[wet breach]

you are not bad, just not understanding that your class is a bit dynamic. But we will go with your example for the time being

[wet breach]

ok using this , where you have config.yml specified you would just instead do "./config/config.yml" I think this should create the necessary directory, worse case scenario it creates a file named that way lmao.

if that happens, I have alternative ways to creating directories 😛

cool part is there is many ways to do this XD

[timid hedge]

but some time ago (probably 1,5 years ago) i made this myself but i have resat my pc since... but i remember the plugin making the folder and the file itself tho

is it because i havent made a file called config.yml under "resources"?

[wet breach]

well in spigot/bukkit config.yml gets created on its own with using the api methods or if you include config.yml inside of the plugin jar. The methods I have shown so far should be used for yaml files other then config.yml because all you are doing otherwise is just being redundant lol

[timid hedge]

i just found this in the console
java.io.IOException: Den angivne sti blev ikke fundet translated to english it is:

i think its because you have 3 dependencies that is the same

[wet breach]

oh right I see our problem now

[faint meadow]

Which one should I use then, I have tried each one separately

[timid hedge]

the one for the version your making a plugin for

[waxen hound]

does getEntityId return the id you need to feed into a packet with protocollib

believe this should work

forgot that the first part of our File() method was the path and the second was the file name

[thorn isle]

iirc yes

[wet breach]

changes I made, makes it so that if you didn't want to use a path, and instead just want the plugin folder it is possible with a boolean option

[timid hedge]

thx, idk last time i made a config file i didnt have to locate the location and all this... but wdym if i dont want to use a path but the plugin folder?

at filePath = this.Path im getting an error, should i just make; private String path; and at filePath = plugin.getDataFolder().toString; it dosent give any fixes for that, the error is at .toString;

[waxen hound]

I have this code as a packet listener:

    public void onPacketSending(PacketEvent event) {
        PacketContainer packet = event.getPacket();

        UtilLogger.getLogger().info("Sending EntityMetadata to " + event.getPlayer().getUniqueId() + " (ent id = " + packet.getIntegers().read(0));
        Entity target = packet.getEntityModifier(event.getPlayer().getWorld()).read(0);
        Player ply = event.getPlayer(); 
        if(target == null) {
            return;
        }

        UtilLogger.getLogger().info("Found armorstand");

        LeaderboardHologram holo = this.leaderboardManager.getHologram(target);
        if(holo == null) {

        }
 
        UtilLogger.getLogger().info("Found holo");
...

[thorn isle]

honestly if you're targeting paper, just use the userdev gradle plugin and build against nms

everything is much easier and you can see the nms sources to investigate problems like these

and ever since the runtime remapping and mojmapped servers, it's fairly stable across versions as well

in this case, looking at nms, yes, that should return the network id for the entity

it returns nms.Entity#id which is also passed to the packet constructors by the entity, e.g.

[waxen hound]

i can only assume that im writing the packet wrong then?

[thorn isle]

or you have the wrong entity, i suppose

[waxen hound]

maybe its losing reference to the entity somewhere

[thorn isle]

looking at the packet record, the first int is indeed the eid, so that part should be right

[waxen hound]

they should be in spawn chunks

yeah i think the problem is the entities being different

im spawning them on startup

i guess its before spawn chunks are loaded

[thorn isle]

that'd make sense for the very low ids you have vs the much higher ids the server sends

best always hold a reference to the entity and check if it's isValid

[waxen hound]

is that spigot provided functionality?

i just added a chunk ticket when i create the entities and that fixed it, so our hypothesis is correct

[thorn isle]

i think isValid has existed ever since craftbukkit and the dawn of time

[waxen hound]

ah, is it just Entity#isValid

[thorn isle]

any time you hold a reference to an Entity for longer than a tick you should in principle check that before next using it, as it could have become invalid in the meanwhile

or strictly speaking any time flow control leaves your local code, as it could be e.g. killed by other plugin code

[timid hedge]

idk if you can answer this i asked earlier
idk last time i made a config file i didnt have to locate the location and all this... but wdym if i dont want to use a path but the plugin folder?
at filePath = this.Path im getting an error, should i just make; private String path; and at filePath = plugin.getDataFolder().toString; it dosent give any fixes for that, the error is at .toString;

[wet breach]

well, I guess you could remove the toString part

so far all of my help I been giving I have not been using an IDE 😛

I just wasnt sure if plugin.getDataFolder() is already a string or whatever

can't remember everything, despite I been doing alright for the most part lmao

[timid hedge]

... yea, thx for your helping me but i guess ill try get this done and then learn how to use java or just do that now

[echo basalt]

getDataFolder returns a File object

if you're on paper there's getDataPath which returns the nio Path

File configFile = new File(plugin.getDataFolder(), "settings.yml");

...

Path configPath = plugin.getDataFolder().toPath().resolve("settings.yml");

if (!Files.exists(configPath)) {
  Files.create(configPath);
}

type deal

[wet breach]

just keep in mind they are relatively new and still learning lol

[echo basalt]

That's no excuse to not give a good quality answer

[wet breach]

never said that lol

just to keep it in mind

[wild mulch]

I'm trying to develop a plugin with ProtocolLib, How do I get the ItemStack in the SET_CREATIVE_SLOT packet?

[chrome beacon]

You get the item modifier

[wild mulch]

Ok

how do i change the NBT or components of a item

[chrome beacon]

Depends on what you're trying to do

[wild mulch]

I just wanna view nbt and run some checks then change it

[thorn isle]

items don't really work with nbt anymore

i think paper has a method to serialize it into snbt

alternatively you can serialize to bytes and then parse the bytes as a compound tag

[chrome beacon]

You're going to have to be more specific

[wild mulch]

Im developing a anticrash and am running some checks on the nbt to make sure it cannot overflow

[thorn isle]

it might be too late at that point

[wild mulch]

doubt it

[thorn isle]

but assuming it isn't, you can serialize it to bytes with paper, parse it as a compound tag with nms, and then run your inspections on the compound tag

[wild mulch]

but i dont wanna switch my stuff over to paper

[thorn isle]

you can do the same with nms then but dunno where you want to hook into exactly

ItemStack codec something something

[chrome beacon]

If you're going to use nms anyway you might as well use the bukkit helper method to convert the spigot item stack to an nms one

[wild mulch]

Is there any way without using NMS or Paper

[thorn isle]

no

nbt has never been an api feature

there are libraries that will use nms for you, iirc itemnbt or something, but your mileage may vary

[chrome beacon]

Parsing the data yourself is also an option

[wild mulch]

tr7zw
Item-NBT-API?

[thorn isle]

probably

[wild mulch]

kk ill try

[wet breach]

overflow?

if that is your goal you are better off looing at vanilla source code to determine that

[wild mulch]

alright i got it working

How do i Make a nbt list using ITEM-NBT-API

[wraith dragon]

@echo basalt sorry for the ping, any project idea recommendations for learning the abstraction stuff we discussed yesterday? Like a quests plugin?

[echo basalt]

Rewards are the best example

Quests not so much

It could work but quests are more about abstraction

[wraith dragon]

Gotcha

I think I'll start with quests then implement rewards

my knowledge with abstraction currently isn't too good

[quaint mantle]

Same

[timid hedge]

How long should i be learning java for before making plugins? if it makes sense?, like 2 hours a day for over a year or two?

[chrome beacon]

Until you feel ready

Everyone learns at a different pace and have their own way of learning

I can recommend Y. Daniel Liang - Introduction to Java Programming and Data Structures if you want a book to read with exercises to do

but there are ofcourse many online tutorials as well if you prefer

[timid hedge]

this one?

i cant send photos...

https://www.linkedin.com/posts/y-daniel-liang-00763b3a_introduce-liang-java-revel-with-codegrade-activity-7211100591828135936-yKyS

idk if you can see it here

[chrome beacon]

Yeah that looks like a video made by the author

[timid hedge]

Does it teach some things that codeacedemy dosent or teches it more in depth? right now im just using codeacademy idk if its good or not

[chrome beacon]

I've never tried codeacademy so I can't say

You can check your local libraries for the book

since it's quite common in universities it's likely there are a couple copies you can borrow

or find a pdf somewhere online

[timid hedge]

is it this one? https://dpvipracollege.ac.in/wp-content/uploads/2023/01/Introduction.to_.Java_.Programming.8th.Edition.pdf

[chrome beacon]

That looks like quite an old copy

but yes that is it

[timid hedge]

alr, do you know where to buy the new version of the book?

amazon?

[chrome beacon]

I got mine from Amazon since it was the cheapest option

[timid hedge]

what edition is the new one?

the link is i sent is the 8th

[chrome beacon]

13th

I believe I have the 12th since that's what I needed for my course

[timid hedge]

thats the one i want right, its not something like i should read from 10th edition up to the newest to understand everything right?

[chrome beacon]

No he just updates them with new content

You do not need the older versions

[timid hedge]

there is so many thats shows up..
https://www.amazon.com/s?k=y+daniel+liang+java
and i dont hope its the 1st one that costs 188 USD

[chrome beacon]

yeah that's the 11th edition

The book is quite expensive since it's quite long

mine is over 1000 pages

but as I said take a look at your local libraries and see if they have a copy

if you feel like it's useful you can buy it or keep borrowing it

[timid hedge]

alr thx, but from what i can see the 13th edition is only online

[thorn isle]

You definitely don't need a 200usd 1000 page book to write bukkit plugins

[chrome beacon]

^ this is true

[timid hedge]

i wouldnt ever use that much on it, it was just because it was the first the showed up

[chrome beacon]

188USD is like twice the amount I spent on my copy

and that's (amazon one not mine) an older edition as well

[ivory sleet]

I wouldn’t say it’s worth the hassle to prepare yourself, just code some plugins and apply what you learn in them, when you learn more and teach urself new beliefs just make sure ur code reflects those changes

[thorn isle]

only preparation you really need is maybe a couple of beginner tutorials on codeacademy or whatever so you know the language syntax

the language syntax is very simple, there are only really a few symbols and a few rules that govern how you can put them together, far easier than english for example

beyond that, it's all about problem solving, which you won't necessarily learn from any number of tutorials or "preparation"

[timid hedge]

yeah but its just diffucuelt to find out how i make examlple config files and make the code for it without it being too basic and idk where to learn that..

[thorn isle]

you look it up

[timid hedge]

i have tried

[thorn isle]

looking up things is a big part of problem solving

[timid hedge]

yesterday i used like 3 hours trying to figure it out

and i ended up with nothing

and afterwards i asked in here

[thorn isle]

you're having difficulty with it because you're unfamiliar with the language syntax

[timid hedge]

and where do i learn the language syntax

[thorn isle]

codeacademy or whatever, the basic tutorials will do fine

[timid hedge]

alr thx

[thorn isle]

but again like i said that's only the very first thing and there isn't that much to learn or "prepare" there; you just need to know what certain words mean so you can effectively look things up

[pseudo hazel]

also whats wrong with it being basic

[timid hedge]

i mean i dont want to make a config file buy making a new file in resources and do it that way but make the config file inside a class si it makes more sense when i have more than 1 config

[thorn isle]

there's nothing basic or wrong about having the config as a file in your resources

some plugins don't do it that way, but it is by far the most established and common way of doing it

[pseudo hazel]

how else would you even do it

[timid hedge]

yea but i just feel like if i have them all at the same place is makes mroe sense

[thorn isle]

generating it from sources, like towny does

i kind of prefer it personally because it allows the config keys to be linted and checked at compile time against typo's, but it isn't as flexible and has its own problems

[thorn isle]

if you want them all in one place, put them all in config.yml

[pseudo hazel]

wdym sources

[thorn isle]

as in you have say a class with public final fields holding objects, each object representing a config key-value

[timid hedge]

but can i then still do all the things like, if a value dosent exist it adds it (if someone removes a value by mistake) and it dosent override on server start and i can get the values out of the configs (if i have config.yml and permissions.yml and messages.yml) ?

[pseudo hazel]

thats how my configs work, but I have a general config file that I can still edit by hand for the comments etc

[thorn isle]

public final TimeValue TELEPORT_COOLDOWN = new TimeValue().withDefault(10_000L);

[pseudo hazel]

but then it just gets updated with the correct default values for new options that get added in updates

[thorn isle]

having separate configs doesn't have anything to do with being able to update them

[pseudo hazel]

the way my config works is it loads the version in the plugin folder, then it loads the version in the jar and puts the jar version into the plugin folder with values found in the existing file from the plugin folder

[thorn isle]

my advice here would be to learn to walk before you try to run; don't try to homebrew your own configuration framework with versioning and updates and all those things, that's complicated

[timid hedge]

but how do i do it when im having more? because i need to use the .saveDefaultConfig right? and as i understand thats for 1 config but how do i do it with 3 configs?

[thorn isle]

just stick with having a configuration file that you read things from

if something is wrong in the config, print a warning in the console; don't try to "fix" it for the user

e.g. if something is missing, print "X is missing in config"

[ivory sleet]

There is another method to do it for other files not named config.yml

saveDefaultConfig is a convenience method

[pseudo hazel]

you have to save it more manually using saveResource because saveDefaultConfig is specifially for config.yml

[thorn isle]

https://bukkit.org/threads/how-to-reload-custom-configs.263595/

this is acceptable

[ivory sleet]

mfw bukkit forums

[timid hedge]

i dont understand what you mean..

[thorn isle]

first search result

[ivory sleet]

the method saveDefaultConfig() is a convenience for saving the config file named config.yml specifically

if you don't know what convenience means u might wna google that word :>

[timid hedge]

yea and thats what i meant and thats why i wanted to make a clas that can manage the config files because savedefaultconfig is for 1 file

[thorn isle]

remember how i told you to go learn the basics so you know what words mean

[timid hedge]

thats what i have been trying to say...

[thorn isle]

    public void saveDefaultConfig() {
        if (!this.configFile.exists()) {
            this.saveResource("config.yml", false);
        }
    }

this is saveDefaultConfig

[timid hedge]

i havent used it like that before...

[pseudo hazel]

thats the implementation

[thorn isle]

this.configFile is a File representing the config file

this.saveResource extracts the file from your jar into the plugin directory

passing false to it means it won't overwrite it if it already exists

now do this but with a File and a path representing your custom config file

[timid hedge]

but is there a way to make it overwrite some values if some values dosent exist

[thorn isle]

no

again, updating and versioning configs is complicated

do the basics first

get into the complicated things later

[timid hedge]

should i do it the same way as the person the the bukkit forum you sent

[thorn isle]

if you want sure but i'd advise against trying to "fix" a broken config

[ivory sleet]

usually when you wanna update from one format version to a newer format version the classic way of doing it is

• read the old format from disk
• update it in memory for the time being (like fixing and filling in missing values etc)
• write the new format when needed todisk

[pseudo hazel]

you can fix a broken config perfectly fine

[thorn isle]

you can but he can't even figure out how to save it or to load it on his own, so let's leave that for later

[timid hedge]

i can

[pseudo hazel]

I load in the old file, then create a new file, and then put the old options back into the new file

[timid hedge]

lol

[thorn isle]

clearly not

[timid hedge]

i dont think you know what i want to do...

[pseudo hazel]

then the new file will have the old options + the new ones

[thorn isle]

you spent 3 hours last night with frostalf trying to load a config

[timid hedge]

because i wanted to do it on another way

and you clearly dont understand it...

[ivory sleet]

if you want god tier versioning

[thorn isle]

just use configurate

[ivory sleet]

you could throw urself at DataFixerUpper

[pseudo hazel]

thats usually overkill for a general config

atlesst in my case

options rarely change, they either get removed or added

[ivory sleet]

i mean its more for data

not configing but yea

[thorn isle]

i think he meant configurate probably

[pseudo hazel]

yeah ig other config files it could be a different story

[thorn isle]

configurate is definitely overkill for basic things

[pseudo hazel]

no I meant datafixer is overkill for what we are trying to do now

[thorn isle]

but properly updating configs while retaining correct formatting and comments isn't basic

[sly topaz]

I would believe the other way around

[thorn isle]

oh for sure, DFU is a nightmare

[ivory sleet]

idk about nightmare

[sly topaz]

configure is fine for simple things, it gets annoying when you have anything mildly complex in a config

[pseudo hazel]

configurate is overkill too but that just depends on your workflow

[thorn isle]

yes my convenience class of 1,500 transformation registrations

[pseudo hazel]

I usually dont like to use too many deps but its fine if you do

[ivory sleet]

I mean configurate does one thing good

it fixes broken libraries like snakeyaml and represent them with a good node structure

[sly topaz]

it goes against OOP so it kinda is for what the standard of a Java library is

[ivory sleet]

yea but java left strict OOP long time ago

[pseudo hazel]

oop is overcooked anyways

[ivory sleet]

just look at what they're doing for generics, lambdas, data orientation etc

[sly topaz]

I'd say they took the functional approach a bit too much for what they wanted to do

[ivory sleet]

Well my take on DFU is that its a perfectly engineered library given the goals of it

for ur average config maybe not the library ud use

but as soon as u wna scale with lets say a dsl language a large set of instances in that dsl, or more so just data formats in general

[thorn isle]

the readme is like 50% by length links to 1000-page phd papers that were used in and written on it

[ivory sleet]

dont get me wrong, u couldve written the data transformation optimizations in an imperative way, but then u lose the ability to pick up on certain traits and properties

[thorn isle]

i don't know if that's good or bad but it's definitely something

[ivory sleet]

yea, but in practicality u rarely every need to type out any of their functional constructs

[sly topaz]

they did cook a bit too hard with the justifactions, probably because mojang wouldn't let whatever team was in charge of it go ahead without doing that much lol

[ivory sleet]

u only ever use like their dynamic operations, codecs and data fixers

and their dsl to navigate and rewrite data types

[sly topaz]

I'd want to try and use it outside of Minecraft to have a more clear picture of it, tbh

I just haven't had the opportunity to

[ivory sleet]

thats the theory thats backing up what the implementation allows DFU to be as powerful as it is

u dont need to touch the impl

meaning u dont need to read the 1k pdfs

[slender elbow]

and to think that codecs weren't part of DFU originally

it was just data fixing

[ivory sleet]

true

[ivory sleet]

yea I mean i think the library still needs to be a bit more engineered since its still kinda strongly engineered towards the satisfaction of minecraft itself

[slender elbow]

you can totally use it outside of minecraft, it's not as bad as many make it seem, it just has a couple of methods in the Schema that are specific to Minecraft that you need to implement or the whole thing blows up

[ivory sleet]

yea I mean i think it lacks a bit of qol, for example shipping more codecs for std types, and also that, but there's also some undocumented invariants

which u just run into and have to deal w on the spot (maybe not that big of an issue)

[slender elbow]

for the data fixers, at least for me, it did take quite a bit to wrap my head around the whole type shape thing, there is some level of schema repetition depending on what kind of transformation you need to do, and i don't really understand why minor schema versions even exist lol

codecs are the easy part i reckon

[ivory sleet]

my assumption is that subversioning is to just fix like smallers patches or bugfixes for a major version, since u wna be able to update from any old version?

instead of creating a new major schema maybe?

[slender elbow]

it would be nice if the serialization part was separated from the data fixing into a separate library tbh

[sly topaz]

that kinda defeats the point of it, no? DFU always seemed to try encompass the idea of "serialization with migration in mind"

you could separate the two but still use them together ig

[slender elbow]

serialization was added separately, originally it was only data fixing

they aren't strictly tied together from what I know, they do share, like, a couple of classes in common but besides that they really aren't

[ivory sleet]

yea like pretty sure dynops is pretty necessary for rewrite rules

[sly topaz]

yeah but without serialization it'd mean plugin their data fixing system on an existing serialization library which would probably be kind of awkward in the end

I assume that's why they ended up implementing serialization on the library

[ivory sleet]

u still likely need to depend on another serialization lib, like if u wna have anything else than json and java ops

[slender elbow]

all i'm saying is there have been times where i just wanted to write basic codecs usage without caring about data migration, that's all

but at that point i would just use jackson

[sly topaz]

can someone please think about the migrations!!

[slender elbow]

yeah it doesn't handle serialization itself, just mapping data between domains and then you can shove that into a record

but that's not what i'm saying lol

[sly topaz]

https://tenor.com/bv57H.gif

[ivory sleet]

oh ye no that was to javier

but def could a separate dfu lib that depends on the serialization lib

[hard socket]

is BuildTools still the best way to get NMS source code?

[chrome beacon]

yes

if you're talking spigot

if you just want to dig around and see how things work I recommend a Fabric workspace since it attaches sources better

though you'd be missing spigot specific stuff

[hard socket]

hmm good to know thanks a lot!

what about paper tho? if I may ask

[chrome beacon]

if you're making a Paper plugin you can use Paperweight

[sly topaz]

paperweight is fine, I usually still just clone the paper repo because IntelliJ isn't as good at searching usage/implementations of a given method/field of compiled classes (the API classes are in source form but the internals ones aren't)

[hard socket]

will work around that thanks guys

[chrome beacon]

So the main paper repo attaches all decompiled sources but paperweight does not?

guess I'll have to give the main repo a try

[thorn isle]

i do seem to have the sources for nms internals attached from the paperweight dev bundle

[sly topaz]

every time I have a plugin with paperweight it asks me to attach sources when it comes to internals

but since internals don't ship a -sources jar, there's nothing to attach

or at least there isn't on my local maven repo lol

[thorn isle]

maybe i've attached them manually at some point, i can't remember

[slender elbow]

unless you have some CI flag/envvar that i can't remember, userdev will automagically attach to the intellij sync task and decompile & apply source patches to make them available

[thorn isle]

i think i probably just attached the userdev cache directory as sources directly

yeah i can't remember having to deal with finding sources to attach manually for a long time

[sly topaz]

I've never had that happen to me and I don't have any special envvars on my system

but I guess this is way out of scope for #help-development, I'll ask in Paper dc later

[slender elbow]

[chrome beacon]

I do remember messing with their api a couple years ago

But it's been a while

[weak wasp]

I have like a dozen+ events I want to subscribe to. I have to make a data class for the sub itself, the subs condition, a method to send the request, make sure that all works, then test with CLI tool to see what the response JSON looks like then make a data class for that, then finally I can actually process the event

I wish there was a better way

[timid hedge]

Im trying to learn some java but i have a question, why dont you always use double instead of switching between double and int

[young knoll]

double stores floating point values (numbers with decimals) and int stores integers (no decimals)

Sometimes you don’t want/need decimals, and math on floating point values isn’t perfect

[timid hedge]

alr thx, because i just feel like i cant find a time where i woudlnt use double instead of int (i know int is the right way but i just though about it)

[thorn isle]

for anything that can't be fractional

for example, in minecraft, you can't have 1.5 dirt blocks in your hand

you can have 1 or 2 or any whole number up to 64, but you can't have partial items in a stack

therefore it is represented with an int, and not a double

[timid hedge]

yeah but i mean you can do double amount = 2; and you can also do int amount = 2;

[thorn isle]

yes

but you can do double amount = 2.5

which would be wrong

you can't do int amount = 2.5

so it forces you to be right

[timid hedge]

yeah i know but what i meant is just why not always use double? when double can be both integer and . numbers

[thorn isle]

because, like i said, sometimes you don't want it to be possible to use .

an itemstack can't have .

so you use int, which stops you from having .

[weak wasp]

Also int takes up less memory than double so int processes faster.

[timid hedge]

alr thx

[young knoll]

Well yeah the equivalent to int would be float

Both 32 bits

But either way you don’t want decimal values for stack size to even be possible

[buoyant viper]

1.0 + 2.0 = 2.999999999998

https://tenor.com/view/omegalul-lul-lulw-twitch-emote-gif-13523263

not rly bc i think its a bit more reliable adding whole numbers with no trailing decimals but

[remote swallow]

i think you mean 0.1 + 0.2 = 0.30000000000000004

[buoyant viper]

yes

[remote swallow]

https://0.30000000000000004.com/

[buoyant viper]

just store everything using BigDecimal

ezpz

[chrome beacon]

👀 that's a real website

[remote swallow]

yup

[buoyant viper]

True

something i had to consider while working on an eco system

ended up storing balances as longs LOL

decimals will only be visual flair, transactions will act only in whole numbers

[worthy yarrow]

Love when my formatting fucks up and still displays the .12000000000002

[young knoll]

Clearly you gotta used fixed point numbers

$2.99 = 299

[worthy yarrow]

Gross

[waxen hound]

this is how a lot of financial infrastructure does it

its called fixed point arithmetic

i believe

[buoyant viper]

yes

[buoyant viper]

pretty much

just dont ask me how a % of the value works (it just doesnt)

[waxen hound]

wdym

[buoyant viper]

oh i guess i could explode the value

[young knoll]

Some languages have built in types designed for currency

Like C#s decimal

[slender elbow]

Java has BigDecimal for that 👵

yeah because I just added the paper mehtod through reflections lmao

but it wont' do anything for spigot

am I meant to interface with that via spigot api or by injecting json into players?

idk

seems like it's just a bunch of json if I don't want to use a rsp right

[worldly ingot]

There is a Dialog type provided by Bungee Chat

Then Player#openDialog() iirc

[torn shuttle]

is it possible to do it in base spigot?

[worldly ingot]

Bungee Chat is base spigot?

[torn shuttle]

is it?

the methods I'm trying to use are giving me a class not found thing

like

Dialog notice = new NoticeDialog( new DialogBase( new ComponentBuilder( "Hello" ).color( ChatColor.RED ).build() ) );
        player.showDialog( notice );

dialog gives class not found

am I looking in the wrong place?

[mortal vortex]

Are you using bungee chat?

[torn shuttle]

I am not which is definitely the problem here

I guess I'm maybe confused, is bungee chat a discrete system from base spigot that also needs to be installed? I thought it would be

hence me not having the class when running

[echo basalt]

It's a separate module for convenience but it's bundled with spig

[torn shuttle]

ok so should my code not be giving a class not found or what am I missing here

[echo basalt]

it doesn't exist on paper

[mortal vortex]

https://javadoc.io/doc/net.md-5/bungeecord-dialog/latest/index.html

[torn shuttle]

oh if it doesn't exist on paper I'm kinda fucked, too many of my users use it

[echo basalt]

time to make a spig and paper module thingy

[torn shuttle]

I think this env might be paper, idk I have htem thrown in at random

[echo basalt]

adventure for paper, bungee chat for spig

[mortal vortex]

can’t you just use bungeechat?

[echo basalt]

or you can shade adventure

[torn shuttle]

I'm not going to do that

that's way too much effort

[mortal vortex]

if bungeechat is serializing, you could just shade bungeechat-dialogue because it’s WAYYY smaller than adventure.

The dialogue package is hardly that many classes.

[torn shuttle]

I don't know if i'd rather just deal with raw json

hm shading bungeechat-dialogue isn't a bad idea

it is tiny yeah

[mortal vortex]

Say W abb3v rn

[torn shuttle]

checking the size before I comming to a w

[mortal vortex]

thank you sir

[sly topaz]

I don't think you have to shade it, do you?

[worldly ingot]

Does it not? I was under the impression they had a fork that just added @Deprecated to everything lol

If they just straight up removed the module, that would be the first major API break

[quaint mantle]

Hi, help pls. I want to set up a command (for example /spawn) so that it has a 5-second delay before execution and a 30-second cooldown, but the teleport should only cancel if the player takes or deals damage, not if they move. Currently, the command executes instantly. Are there any plugins or solutions that can handle this behavior?

[thorn isle]

schedule a repeating task that checks the position periodically and cancels itself in 5 seconds, teleporting the player if they haven't moved

and cancels itself if the player moves

a self-cancelling BukkitRunnable is useful for this

for the cooldown, keep a UUID -> Long map of timestamps of last usage; check the map when the command is run and insert into the map when the player teleports successfully

uuid being the player's unique id

[quaint mantle]

It’s unlikely that such a plugin doesn’t exist; I’ve seen it on several servers, apparently not configured, but completely identical. Also, I need it so that different ranks or permissions can have different times.

[hybrid spoke]

#help-server

[thorn isle]

this is dev-help

we make plugins here

if you want an existing plugin, go to ^

[slender elbow]

it just stopped getting updated

[worldly ingot]

Oh, well then, there ya go

Figured the API break would happen eventually

[slender elbow]

I mean

bungee chat is just a subset of the spigot api

it isn't the first bit that stopped getting updated.. like, the whole of spigot

[worldly ingot]

There haven't been many large API additions to Bukkit or Spigot for the last little while

Dialogs feel like the most significant because people actually want to use them

[slender elbow]

i guess

[worldly ingot]

Yeah. Yeah you should guess

[quaint mantle]

Hey, I wanted to ask, how Plugins detect the Client etc. like "... joined with fabric" or "... joined with feather-fabric" or "... joined with lunarclient- 218293-dev". Someone already told me that this will most likely not be uncertain and not reliable. But I dont really mind about that, I just didnt understand how back when the person told me, so I'd appreciate an example!

[chrome beacon]

The client tells the server what they are

[glass zealot]

So how do I detect it?

[slender elbow]

didn't you get an answer in the paper discord, like, last week when you asked?

[glass zealot]

Wait I did?

I only remember that everyone told me its not reliable and stuff

[slender elbow]

yeah, because it isn't

[chrome beacon]

It's not reliable since it can be changed to anything the user wants

[slender elbow]

and after that you were given the method that tells you what you want

How would i make the warden attack a certain player instead of the one who just hit it? it seems vanilla forces the warden to chase a player no matter how many times they die, it will never follow a new player

but i need it to chase a new player for a custom system

[wraith dragon]

The Warden class implements the class Mob, which has a method #setTarget(LivingEntity target), perhaps you can use that

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/Mob.html#setTarget(org.bukkit.entity.LivingEntity)

[torn shuttle]

somehow wiht each passing day intellij gets worse

how is this happening

do they just want to lay down and let cursor walk over them or something

this is the second time today it has hard gotten stuck

when opening a project

like 100% unresponsive

and it's the 4th time I have to force quit it

it also broke my git again

[summer scroll]

On top of that @wraith delta you could listen to EntityTargetEvent, just to make sure it doesn't target players that you do not want to be a target https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/entity/EntityTargetEvent.html

[wraith delta]

I tried that, but the thing is minecraft has that aggression internally hardcoded which somehow wont budge. the target event works for other mobs, its just not working for warden.

[wraith dragon]

I thought it was just me lol! Same happened to me this morning

[wraith dragon]

You might have to do it the NMS way then, if those solutions didn't work

Hi guys!
I'm trying to set a config section to null to erase it but when I check the file everything is still there. Can someone look at my code to see if I'm doing it right? (Yes I am saving the file after editing)
I set up a loop to tell me every key under the node and it successfully printed them in console but still did not erase them from the file.
There are no errors in console.
Here are the methods involved. Let me know if you need to see more.
https://pastes.dev/cwMTh1ZOki

[summer scroll]

Maybe you're using different cached FileConfiguration?

Can't tell much from your code, loading and saving looks okay to me.

[potent atlas]

Adding to the file works fine, it's just removing that is the problem. Setting to null is how it's done, right?

[summer scroll]

Yes, setting to null then save.

Damn my bad

I have been trying to make a custom model in block bench and place it into model engine so I can run it on my server and later connect it to mythic mobs, I've tried everything, but everytime I make a model and put it in the folder it dont work. However after playing around I could confirm the bbmodel is working with a different file called herobrine. However I cant figure out why I keep getting this long error talking about naming issues...

What am I doing wrong?

Heya! Does anyone know if there were any changes to bossbars? There's a ghost bossbar that won't go away no matter what I do.. Even trying to remove it using /bossbar just removes the actual bossbar my plugins creates

[sly topaz]

does it stay even if you log out

[tame wolf]

Yep, if I log out and back in it's still there

[sly topaz]

did you register a persistent bossbar perhaps?

if so, you can remove it with Bukkit::removeBossBar

[tame wolf]

🤨 A few months ago I had an issue where the bossbar wouldn't work unless I used a persistent bossbar

[sly topaz]

there shouldn't be anything that requires persistent bossbars for them to work

that being said, I don't know why it is getting duplicated there

[tame wolf]

Alright, I'll try making it non-persistent 😁

Now it won't show at all once I relog

[hybrid spoke]

possibly show us the code so we don't have to search the needle in the hay

The method I use to show the bossbar to the player:

    public void showEnergyBar(RunePlayer player) {
        if (!Runecraft.getInstance().getRegistry().getInitiated().containsKey(player.getUUID()) || !Runecraft.getInstance().getConfig().getBoolean("RunecraftEnergyBar.Enabled"))
            return;
        EnergyBar bar = Runecraft.getInstance().getRegistry().getPlayerEnergyBar(player.getUUID());
        BossBar bossBar;
        int energy = Runecraft.getInstance().getRegistry().getEnergyReservoir(player.getUUID()).getEnergy();
        if (playerEnergyBars.containsKey(player.getUUID())) {
            bossBar = playerEnergyBars.get(player.getUUID());
            bossBar.setTitle(GOLD + "Runic Energy: " + String.format("%,d", energy));
        } else {
            bossBar = Bukkit.createBossBar(GOLD + "Runic Energy: " + String.format("%,d", energy), BarColor.valueOf(bar.getColor().name()), BarStyle.valueOf(bar.getStyle().getSpigot()));
            playerEnergyBars.put(player.getUUID(), bossBar);
        }
        bossBar.setProgress((float) energy / Initiation.TierCapMapping[Runecraft.getInstance().getRegistry().getInitiated().getOrDefault(player.getUUID(), 0)]);
        bossBar.setVisible(true);
//        Logger.fine("Bossbar is " + bossBar.isVisible() );
        if (!bossBar.getPlayers().contains(Bukkit.getPlayer(player.getUUID())))
            bossBar.addPlayer(Bukkit.getPlayer(player.getUUID()));
        if (Runecraft.getInstance().getConfig().getInt("RunecraftEnergyBar.Timer") != -1) {
            if (playerEnergyBarsTaskIDs.containsKey(player.getUUID())) {
                Bukkit.getScheduler().cancelTask(playerEnergyBarsTaskIDs.get(player.getUUID()));
            }
            playerEnergyBarsTaskIDs.put(player.getUUID(), scheduleDelayedTask(() -> {
                bossBar.setVisible(false);
                playerEnergyBarsTaskIDs.remove(player.getUUID());
            }, 20 * Runecraft.getInstance().getConfig().getInt("RunecraftEnergyBar.Timer")));
        }
    }

Which I also call in the OnPlayerJoin event

[hybrid spoke]

you should really use variables instead of calling the same methods all over again

would make it more readable

[tame wolf]

Pretty readable to me, I think it's just the discord formatting making it harder for you...

[hybrid spoke]

no, it's the code duplication by always calling getInstance().method1().method2().method3(), which could be much shorter with

var descriptiveVariable = getInstance().method1().method2();
var energyResult = descriptiveVariable.method3();

but that's not the problem here - it's hard to tell where the duplicate bossbar is coming from. i would guess it's either a failed cleanup or the code is executed twice somewhere

[tame wolf]

Anyways, I uncommented the debug line for whether the bossbar is visible

It says the bossbar's visibility is true

But that's not the case, as there's no bossbar 🤷

[tame wolf]

It's definitely not being executed twice, but after I made the bossbar non persistent it's definitely acting strangely

There are only five places where I call the method for the bossbar, and neither of them work for making it re-appear

Unlikely that it's being executed twice, as this is the only place in my codebase where I create a bossbar

I'll try making it persistent again 🤔

Alright... So after making it persistent on my dev server, it functions fine, however, the production server, where I originally noticed the double bossbar issue, now has zero bossbars! :D lol

[autumn cave]

In https://hub.spigotmc.org/versions/ is it safe to assume that builds between version X (inclusive) and version X+1 (exclusive) are all builds for version X?

For example: 1.21.1.json is at Build #4344, and 1.21.2.json is at Build #4398, so:
Builds 4344 till 4397 are builds for version 1.21.1.

Is this correct, and is this the only/best way to know the build versions per minecraft versions?

[nocturne pollen]

Hey can anyone help me?

i need to use player.performcommand but this dosnt work with 1.21.8... i need to trigger a proxy (velocity) command

do i really just need to have like 5 <script src=file.js> tags?

[mortal vortex]

r u using ES6 Modules?

[buoyant viper]

nah im rawdoggin this shit (truth)

just a folder with index.html and a js file

[mortal vortex]

me and ur mom

so just split the JS into files, export the functions, and then inport them in the main js

[buoyant viper]

guh

gotta learn how exporting works :(

[mortal vortex]

// js/somefile.js
export function boykisser(xyz) { /* ... */ }
export function fortnite(fn, delay) { /* ... */ }

// js/otherfile.js
export async function skibidi(id) { /* ... */ }

// js/main.js
import { boykisser, fortnite } from './somefile.js';
import { skibidi } from './otherfile.js';

[young knoll]

I think you literally just do export function Ligma()

[buoyant viper]

what about a js class

does a browser understand the import and export keywords?

[mortal vortex]

just use typescript

its acronym is that of our Queen

[torn shuttle]

what causes a teleport of a player to return false? just cancelling the event?

I'm having a weird problem with it

[rotund ravine]

Probably invalid too?

[torn shuttle]

that's kind of the thing, best I can tell it's valid

it's very weird

[echo basalt]

dead entity?

[torn shuttle]

def not

[echo basalt]

riding something and that something not teleporting

[torn shuttle]

it's my player entity

also not riding

waiiiiiiiiiit

wait

[echo basalt]

having a passenger

[torn shuttle]

yeah

I have a display passenger

that does it?

[echo basalt]

Yup

not sure if it's valid on spigot but ik on paper you have teleport flags you can use

it once took me like 2 hours to figure out why tps werent working

[torn shuttle]

holy shit

let me check but I def have one

why on earth why on earth would you do this

[echo basalt]

something something position desync or whatever

[torn shuttle]

yeah that was it

[echo basalt]

not as fun as folia killing itself the moment you schedule something onPlayerQuit

[torn shuttle]

that's crazy stupid

[echo basalt]

legit just hard crashes

[torn shuttle]

seems reasonable

huh? is there a proper way around the "player can't teleport with passengers" issue on paper now?

can i finally put my hacky clientside passenger on passenger bandaid to rest?

hey y'all 😌 I was wondering if anybody was knowledgeable on Custom Model Data to get custom textures working in-game? I've got the resourcepack set up, however I'm struggling to get the textures to actually apply in-game. I know that the CustomModelData was deprecated in favour of CustomModelDataComponent, however neither of the two are working for me 😅 I'm not really sure what's wrong with my json files and why it's struggling to be mapped unfortunately :/ I've attached the zip of my pack directory, which in-game says has loaded successfully, however no texture seems to be getting applied. I'm on 1.21.7 (running Paper but my plugin is off of Spigot)

public ItemStack getItem() {
    ItemStack item = new ItemStack(Material.ARROW, 1);
    ItemMeta meta = item.getItemMeta();
    if (Objects.nonNull(meta)) {
        ArrayList<String> lore = new ArrayList<>();
//        CustomModelDataComponent cmdc = meta.getCustomModelDataComponent();
//        cmdc.setFloats(List.of((float) 5));
//        meta.setCustomModelDataComponent(cmdc);
        meta.setCustomModelData(1);

        meta.getPersistentDataContainer().set(ARROW, PersistentDataType.STRING, "diamond");
        meta.setDisplayName(ChatUtils.translateToColor(getName()));
        meta.setLore(lore);
        item.setItemMeta(meta);
    }
    return item;
}

[smoky anchor]

Yep you're using outdated RP
now you need to create an item model definition, there you can check for the custom model data and then apply a specific model
OR you can instead use the itemModel component for itmestack to apply an item model directly without the use of CMD (which is preferred for custom items) This still requires creating a new item model definition tho

You can look at the vanilla RP for inspiration

Also, "which in-game says has loaded successfully" take a look into your client logs instead, I think those might show some error. Maybe, I'm not sure what it would do for nonexisting field.

Additinally, I'd like to suggest using setItemName instead. This will replace the base name an item has instead of using the "anvil name".

• if possible, use translatable (with fallback to your custom name) and create a translation file, en_us is enough to start.

Smh it's en_us

thank you for the info!! Regarding the translatable, it’s in the plans hahaha, I have had all text hardcoded as of now, since my plugin has been just for a little survival server with some friends and I, but I’m planning to open up publicly and I’m stepping it up a notch😎

Just a question regarding the itemModel component… How do I get access to it, and how does the json get linked? I’m still veeeeery new to model data and all, so it’s all foreign to me 😅 If you happen to be aware of a tutorial that I could follow and learn from, that would be awesome! All I’ve been able to find as of now has been on CMD 🙁

I’m assuming it’s just via the getItemModel() method from the ItemMeta, however I’m not sure how it gets mapped to the json

[smoky anchor]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/inventory/meta/ItemMeta.html#setItemModel(org.bukkit.NamespacedKey)
It takes in namespaced key - a resource location of the item model definition file

as test you can simply use a "minecraft:stick" on a stone item

[ancient plank]

Olden days of Minecraft there were some nasty bugs with entities and passengers in chunks unloaded to you, where a player would be floating somewhere across the world for you and a horse would be moving around you. Probably something related to that tbh

i.e. You teleport both the entity and the passenger and it desyncs because of load orders

and now it's broken for someone somewhere

[wooden relic]

amazing, I’ll look into it!! thank you so much c:

@smoky anchor progress!! Thank you so much 🙂 I'll try to figure out how to integrate it to my custom models later on today

Feel free to tag me (with context of our conversation 'cause I might forget)

@smoky anchor hi

[visual zealot]

Hello,
I try to update my old bukkit plugin to spigot. I had this code that would work previously, but unfortunately ItemMeta does not survive to Inventory#setItem().

The output should be 1true, 2true, but it is 1true, 2false. Could you tell me what is wrong here?

    mystack = new ItemStack(Material.WRITTEN_BOOK);
    final BookMeta mybook = (BookMeta) mystack.getItemMeta();
    mystack.setItemMeta(mybook);
    log.info("1"+mystack.hasItemMeta());
    inventory.setItem(index, mystack);
    log.info("2"+inventory.getItem(index).hasItemMeta());

[pseudo hazel]

yes

thats definitely minecraft code

[slender elbow]

I'm not sure

[quaint mantle]

Should be.

[full breach]

need someone whos good at compiling plugins dm me youll be compensated aswell

[slender elbow]

how will i be compensated

!!!

[quaint mantle]

[sullen marlin]

You've done nothing to the book meta though

[visual zealot]

In fact I stripped the part where I set an author before. The full code is here:
if (mystack == null || ! mystack.getType().equals(Material.WRITTEN_BOOK)) { mystack = new ItemStack(Material.WRITTEN_BOOK); } //final BookMeta mybook = (BookMeta) Bukkit.getServer().getItemFactory().getItemMeta(Material.WRITTEN_BOOK); final BookMeta mybook = (BookMeta) mystack.getItemMeta(); if (name != null) { final String myauthor = prefix + "." + name; mybook.setAuthor(myauthor); } else { mybook.setAuthor(prefix); } mystack.setItemMeta(mybook); ByteCart.log.info("1"+mystack.hasItemMeta()); ByteCart.log.info("2"+mystack.getType().isItem()); ByteCart.log.info("3"+index); ByteCart.log.info("4"+mybook.getAsString()); ByteCart.log.info("4"+((BookMeta)mystack.getItemMeta()).getAuthor()); inventory.setItem(index, mystack); ByteCart.log.info("5"+inventory.getItem(index).hasItemMeta()); inventory.getItem(index).setItemMeta(mybook); ByteCart.log.info("6"+inventory.getItem(index).hasItemMeta()); BookMeta meta = (BookMeta) inventory.getItem(index).getItemMeta(); ByteCart.log.info("7"+(meta.getAuthor()));

and the output is:
[21:36:02] [Server thread/INFO]: 1true
[21:36:02] [Server thread/INFO]: 2true
[21:36:02] [Server thread/INFO]: 310

[21:36:02] [Server thread/INFO]: 5false
[21:36:02] [Server thread/INFO]: 6false
[21:36:02] [Server thread/INFO]: 7null

I expect 5 and 6 to be true

[chrome beacon]

What version are you on?

(send the output from /version)

[visual zealot]

The last : 1.21.10-R0.1-SNAPSHOT

I tried on older 1.20.1 and it works with this version

discord pls

[wild mulch]

how do i parse a entity selector with the spigot api? (Selectors such as '@e[type=pig,distance=..3]'

while being local to the executor

or a entity put in

[echo basalt]

Bukkit.selectEntities(sender, selector)

[wild mulch]

ok

what happens if its invalid

[visual zealot]

My plugin still works on 1.20.4, but starting with 1.20.6 it has the same issue

[weak wasp]

Well guys I'm finally done my plugin which I'm happy about, but now I'm super bored that I have nothing to work on.

[buoyant viper]

port it to Fabric

[weak wasp]

Hmm, never worked with fabric before... Maybe

[daring light]

What would be the best way to share data with two plugins? I'm working on plugin 1 which needs to find out if a player is AFK, and I want to connect plugin 2 which handles that. Ideally I want plugin 1 to not depend on anything, rather plugin 2 having the capability to connect with plugin 1. Is this possible?

[gaunt tangle]

Pinata plugin

Do you know the pinata plugin which is free?

[mortal vortex]

anything u make is free gng

[mortal vortex]

API interface?

and https://hub.spigotmc.org/javadocs/spigot/org/bukkit/plugin/ServicesManager.html

Then hook into it

[visual zealot]

I suppose this is linked to this change: https://hub.spigotmc.org/stash/projects/SPIGOT/repos/craftbukkit/commits/735b2d0d7f10bc3b3a816e103cc86af8cb1ec645#src%2Fmain%2Fjava%2Forg%2Fbukkit%2Fcraftbukkit%2Finventory%2FCraftItemStack.java?f=709

[ripe depot]

when i cancel an InventoryClickEvent, does it still get passed to PrepareAnvilEvent? or does that happen after?

[worldly ingot]

Yeah this is the way to go about it. And to be clear, plugin 1 is the one that would be providing the interface and calling its methods. Plugin 2 would be the one implementing and registering it.

Think of it like this. You want your plugin 1 to know about AFK players. You don't care who or what tells you whether or not a player is AFK, you just want to know if that is the case. The plugin 2 comes in and provides that data for you.

[echo basalt]

make a module that provides API interfaces

make a module that implements them

uh

[worldly ingot]

He said he wants no dependencies on plugin 1. But yes ideally you would have some sort of service providing plugin that both plugins depended on

[echo basalt]

hasMetadata("AFK") be like

[worldly ingot]

That is also certainly an option

and a valid use case for the metadata API

[onyx fjord]

Honestly I'm afraid noone uses it except of vault

[thorn isle]

i use it quite a bit

it's very convenient if a bit verbose

many cases that would typically be handled through events are better handled through a service provider

[quaint mantle]

Hardcoded string 💔 😨

[thorn isle]

can't really do anything better without api between the plugins and cross-dependencies

or i suppose you could have it be configurable in both plugins but that doesn't seem that much better

[onyx fjord]

How do you not hardcode such text

Do you want your metadata keys translatable in config

npc is also very common

[echo basalt]

uh

public final class MetadataKeys {

  public static final String AFK_KEY = "AFK"; 
  public static final String IS_NPC_KEY = "NPC";

  private MetadataKeys() {
    throw new IllegalStateException("buddy are you really initializing this via reflection");
  }
}

[smoky anchor]

damn you're fast

[echo basalt]

I'm used to typing in discord

no need for an IDE

[slender elbow]

yeah but that requires adding a dependency just for a stupid simple "NPC" string

[outer ember]

can somone explain me to how to save a hashmap to my world?

[thorn isle]

depends on what's in the hashmap

not all data types are trivially serializable

[outer ember]

uh

[outer ember]

UUID Intenger

[thorn isle]

are you sure you want to save it directly on the world? instead of, say, a file on disk associated with that world?

if you want to save it directly on the world, you'll need to use the world's PDC; for a flatfile, things can be easier

[outer ember]

Oh my wifi just broke

[outer ember]

the world is better i think

[onyx fjord]

For what purpose

[outer ember]

it not visible by owners

u know what i mean

feels better

[thorn isle]

better access to the data by admins is generally better

[worldly ingot]

I assure you it's still visible to server owners if they have an NBT editor program :p

All data is readable

[outer ember]

I know

[thorn isle]

"it just works" style shoving of things under the hood is usually not the best way to go

[outer ember]

it's not that important

[thorn isle]

either way, i'd probably serialize it into a json string with maybe gson and shove it in the world PDC

[outer ember]

but i dont like it being visible easily
i don't know why

[thorn isle]

or if you want flatfile, in a <world-uid>.json

[outer ember]

it just feels better

[thorn isle]

someone linked you the pdc docs last time you asked

[outer ember]

can somone just tell me how to

[thorn isle]

for gson you can find tutorials online i'm sure

i'm not writing it for you

[outer ember]

it was for item stack

[thorn isle]

world.getPersistentDataContainer()

the API is the same

[outer ember]

no explanation for hashmap

[thorn isle]

serialize it with gson

[outer ember]

i did

[thorn isle]

then put the String in the PDC

gson turns things into strings

you turn your hashmap into a string

then put the string in the PDC

[outer ember]

PersistentDataContainer data = world.getPersistantDataContainer

data. -> no tab complete

[thorn isle]

what

look at the api docs

[outer ember]

i cant use data.set

[slender elbow]

you don't need tab completion when you have the javadocs and other usage documentation :D

[thorn isle]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/persistence/PersistentDataContainer.html

what version are you building against?

don't tell me 1.8

[outer ember]

1.20.1

[thorn isle]

PDC should be on 1.20

let's see your class with full imports

[slender elbow]

should be = is

[outer ember]

it gives me errors

Oh my pcccc

[thorn isle]

let's also see your build script

[smoky anchor]

assuming you typed exactly this into the IDE, ofc this would give you errors

[outer ember]

HashMap<UUID,Intenger> wanted = new HashMap<>();
NamespacedKey key = new NamespacedKey(NovaPolice.getInstance(),"wanteds_info");
World world = Bukkit.getWorlds.get(0);
PersistantDataContainer data = world.getPersistantDataContiner();
String json = new Gson().toJson(wanted);
data.```

if i put .set
after world.getPersistantDataContainer()
it works
but does not works after
data

[slender elbow]

did you just type that out on discord or did you copy/paste from your ide?
