[cerulean birch]

is there any simple to remove x amount of items of a specific material from a player's inventory, without iterating through the whole list? the api has a pretty easy method to figure out if the player has x much of a material, but not for removing .-.

[inner jolt]

PlayerInventory#removeItem(itemStack, items) should work

[cerulean birch]

hm i'll try it out, ty

[inner jolt]

no problem 👍

d;spigot PlayerInventory#removeItem(itemStack, items)

[uneven lantern]

org.bukkit.inventory.Inventory#removeItem

@NotNull
HashMap<Integer,ItemStack> removeItem(@NotNull ItemStack... items)
throws IllegalArgumentException```

Description:

Removes the given ItemStacks from the inventory.

It will try to remove 'as much as possible' from the types and amounts you give as arguments.

The returned HashMap contains what it couldn't remove, where the key is the index of the parameter, and the value is the ItemStack at that index of the varargs parameter. If all the given ItemStacks are removed, it will return an empty HashMap.

It is known that in some implementations this method will also set the inputted argument amount to the number of that item not removed from slots.

Parameters:

items - The ItemStacks to remove

Throws:

IllegalArgumentException - if items is null

Returns:

A HashMap containing items that couldn't be removed.

Does anyone know how to make a right click event where someone right clicks there sword and teleports x amount of blocks?

[neon wren]

Use the interaction event? check if the item right clicked is a sword, grab the location and randomly change the location by offsetting it from the original?

[lyric gyro]

Could you make that a little more in code language sorry haha!

[neon wren]

I'm not trying to spoonfeed you the code.
Use PlayerInteractEvent -> check if player#getItem().getType() is the sword -> Use player#getLocation() to get the current location and randomly determine if you are simply going to change the x, or will do the others -> Set the player's location to the clone of the player's original location and add the offset to it.

[lyric gyro]

ohhh okay cheers that makes sense

[neon wren]

It's based on the latest library by the way, but you'd also need to check if they have a item that isn't air.

[lyric gyro]

okay cool

[pearl topaz]

when using a factory, what is the proper way to deal with enums where you have "subtypes"? for example i have:

is there a better way to do the ARRAY_X enums

i don't want to have to write a new line for every ARRAY_X type if possible, and my ArrayLogger is a generic class parameterised by this X

[kind granite]

thats not really an appropriate time to use an enum

[pearl topaz]

how come?

[kind granite]

because you have generics

are you still trying to do that mutable container thing

[pearl topaz]

is this a bad idea then

[high edge]

Probably

[kind granite]

yes

we told you this yesterday

[pearl topaz]

which part? this is new

[high edge]

I'd assume the entire thing from what I've been reading :3

[pearl topaz]

i dont really mind that part

im just experimenting with factories

[kind granite]

do you really need a factory here

[pearl topaz]

well it's a cleaner way of wrapping all the loggers together i guess

[kind granite]

no

[pearl topaz]

and im initialising them from a config file

so i can do something like

MyEnum.valueOf("Foo")

[kind granite]

do you know the shape of the data from the config file

[pearl topaz]

yes

but for the type of logger

i'm not sure a better way to do it

[kind granite]

use a dao

[pearl topaz]

ok but even if have a data class like

data class loggerValue(type: LoggerType, name: String, sampleRate: Long)
```how does that make it easier to actually instantiate the loggers

unless i have some factory that can accept type and return an object of the type of logger i want

[pearl topaz]

or did you mean something different

[kind granite]

the whole idea of what you're doing

use a dao

[hard wigeon]

How does one get a list of ConfigurationSections in spigot's config API?

eg.

- test: 1
  test2: 2
- test: 3
  test4: 4

I'd want to serialize that into a list of test and test2

ConfigurationSection#getList doesn't allow for a custom object

[fiery pollen]

What if you use ConfigurationSection#getKeys(false) and then just get the configurationsection using ConfigurationSection#getConfigurationSection() and add the configurationsection to a list?

[hard wigeon]

but it's a list, not a object
I could be wrong here, but I assumed getKeys would get me the keys of an object

[fiery pollen]

ow yeah sorry

That example

is that even valid yaml?

[hard wigeon]

should be, yeah?

it's a list of objects

[fiery pollen]

ow yeah

[fiery pollen]

and what about getValues()?

nvm

but if you do getKeys()

What would you get?

[hard wigeon]

let me find out

[broken elbow]

idk if its possible with spigot's yaml stuff. I know its possible with libs like ConfigMe tho

wait

@hard wigeon don't you just use getList?

oh you said it doesn't allow custom objects?

you sure?

[hard wigeon]

not that I can figure out

does spigot's have object deserialization?

[broken elbow]

yeah.

see md's answer

[hard wigeon]

ah

[pearl topaz]

for what?

i appreciate the help but im not understanding what you are suggesting

[wintry shadow]

hello ! How can i save data with my plugin ?

whats is the best method ?

[slim vortex]

An easy method is by using YAML or JSON

SnakeYAML is built inside of the Spigot API, so that's a straightforward option.

[wintry shadow]

okok

[wintry shadow]

ok did you have a good tutorial for JSon ? I can't find something simple :/ for me to understand

[slim vortex]

Google's GSON library is nice.

https://howtodoinjava.com/gson/google-gson-tutorial/ Here's one

[wintry shadow]

ok ok i go test

ty

[wintry shadow]

just last question, mysql is easy ?

[winged pebble]

I recommend just trying it out

and seeing what you think

[slim vortex]

It's neither easy nor hard. It's a good option in some circumstances.

[wintry shadow]

public class Main extends JavaPlugin {

    private Connection connection;

    @Override
    public void onEnable() {
        System.out.println("ON");

        try {
            Connection con = getConnection();
            assert con != null;
            PreparedStatement posted = con.prepareStatement("INSERT INTO users (first_name, last_name, num_points) " + "VALUES ('Théo', 'test', 1)");
            posted.executeUpdate();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public static Connection getConnection() throws Exception {
        try {
            String driver = "com.mysql.jdbc.Driver";
            String url = "jdbc:mysql://localhost:3306/server_test";
            String username = "root";
            String pasword = "";
            Class.forName(driver);

            Connection conn = (Connection) DriverManager.getConnection(url,username,pasword);
            System.out.println("Connected");

            Statement st = conn.createStatement();

            return conn;


        }catch (Exception e){System.out.println(e);}

        return null;
    }


}

ok its work

fiouf

it's not very clean but it works

[lyric gyro]

I'm no Kotlin expert but I'm fairly sure all default parameters must go at the end, after mandatory ones

alternatively you could do blah("blah", sampleRate = 123)

not sure if that would work

[pearl topaz]

thanks, i just fixed it with that example

but i'll put it at the end anyways

[limber lagoon]

Can somebody pls help me kill my bot that's running through a raspberry pi?

I forgot the command 🥲

[winged pebble]

🔨

That should do it

[limber lagoon]

Hammer?

Oh

[winged pebble]

slam slam, then no more bot

[limber lagoon]

Right

[winged pebble]

Or pi 😛

[limber lagoon]

I guess I'm just slow in the head

[neon wren]

still experiencing the issue?

[limber lagoon]

Unfortunately 😦

I also can't get my bot to start

[neon wren]

EDITED: So you can't stop the task, nor start your bot now*

Discord bot?

[limber lagoon]

Sorry I should've clarified, I wanted to end the screen for my bot

But the bot never actually started

The command I'm using to try and start the bot is screen java -jar **BotName**.jar

[neon wren]

To end a terminal instance, have you tried CTRL + D, there will be no warnings attached.

[limber lagoon]

Oh alright, thanks

Let me try that now

[hoary scarab]

screen -r id

[neon wren]

I'm pretty positive, it's not running is because you provided the screen argument in front of java command.

as usually on a screen you'd run for example: java --version to see what sdk you are running.

[limber lagoon]

Hm that's weird, I remember using this exact command a few months back and it worked fine. I'll try that also, thanks again!

[limber lagoon]

How do I find the id?

[hoary scarab]

screen -list

[dusky harness]

screen -S screen_name -X quit to kill it

[limber lagoon]

Ok that's a lot of information lol let me write this down somewhere

[dusky harness]

and ctrl A -> D (without ctrl) to exit without terminating screen

[neon wren]

Possibly you meant sudo instead of screen to run it?

[limber lagoon]

Possibly...

Sorry, give me a second to try all these new commands and give feedback 😅

[neon wren]

For example, you cd into the folder with the jar, and then run sudo java -jar BotName.jar

[limber lagoon]

How do I cd into a specific folder?

I tried cd home/pi as well as cd home\pi which is my bot's folder

Ah

Nevermind

Alright so far I should be good, thanks all!

Ah wait a minute, it seems I'm unable to type any further commands after starting my bot

It just sends me to an empty line

Which means I can't exit the terminal without terminating

[pearl topaz]

anyone know why gradle might be giving me

Error: Could not find or load main class telemetryapp.TelAppKt
Caused by: java.lang.ClassNotFoundException: telemetryapp.TelAppKt
```i literally have `src/main/java/telemetryapp/TelApp.kt`

[lyric gyro]

. is not a valid class/package identifier afaik

[pearl topaz]

mistype

[lyric gyro]

a

[pearl topaz]

i tried adding

sourceSets {
    main.java.srcDirs = []
    main.kotlin.srcDirs = ['src/main/java', 'src/main/kotlin']
    main.resources.srcDirs = ['src/main/resources']
}
```to `build.gradle.` but doesnt work still

[dusky harness]

ctrl a -> d (without ctrl)

thats how you exit a screen without terminating

not sure if theres another way to exit

how would I send someone to jail when coding a plugin

I'm trying to edit this plugin so it send a player to jail rather then setting their gamemode to spectator when they get killed

    eliminate(Player player, Player killer) {
        player.setGameMode(GameMode.SPECTATOR);
        player.sendMessage(ChatColor.RED + "You have been eliminated!");

        InventoryUtils.giveHeadItem(killer, player);

        addElimination(player);
    }

[icy thistle]

edit: how do I ban someone

[dense drift]

d;spigot BanList#addEntry

[uneven lantern]

org.bukkit.BanList#addBan

@Nullable
BanEntry addBan(@NotNull String target, @Nullable String reason, @Nullable Date expires, @Nullable String source)```

Description:

Adds a ban to the this list. If a previous ban exists, this will update the previous entry.

Parameters:

target - the target of the ban
reason - reason for the ban, null indicates implementation default
expires - date for the ban's expiration (unban), or null to imply forever
source - source of the ban, null indicates implementation default

Returns:

the entry for the newly created ban, or the entry for the (updated) previous ban

@icy thistle

[icy thistle]

I'm using IntelliJ IDEA how do I compile a plugin into a .jar file its been a while since I've done this

[dense drift]

Use a build tool like maven / gradle

[icy thistle]

I have plugin running the command jail playername
however the server says Player not found. when I use player.getDisplayName()
but it works when I manually run the commands

Bukkit.dispatchCommand(Bukkit.getConsoleSender(), "jail " + player.getDisplayName() + " dead");
Bukkit.dispatchCommand(Bukkit.getConsoleSender(), "unjail " + player.getDisplayName());

[20:51:30 INFO]: CONSOLE issued server command: /jail TCubed3 dead

[20:51:38 INFO]: Error: Player not found.
[20:51:44 INFO]: jaredy00 issued server command: /unjail TCubed3

[dense drift]

player.getName()

[icy thistle]

whats the difference

[dense drift]

Thats the proper method

And, is there a player named TCubed3 on your server?

[icy thistle]

yes

[dense drift]

Ah

Are you running the SAME command in-game?

[icy thistle]

misread

TCubed3

with the d

[dense drift]

Yeah, typo

[icy thistle]

ok then yes

[dense drift]

Hm

[icy thistle]

I was running the command ingame manually as well to test

and it worked ingame

[dense drift]

/jail TCubed3 dead?

[icy thistle]

I'm using essentials jail command

[dense drift]

The command syntax is /jail <jail> <player> <duration> (reason) afaik

[icy thistle]

duration and reason are both optional

for whatever reason changing it to player.getName() worked

[dense drift]

Good

displayName might contain formatting, like colors

Hi, so I want to make a GUI Inventory, I have the inventory made, but not sure how to remove the players from moving items in it/adding commands to a head that teleports you to a gamemode.

[bitter basin]

would highly suggest using a library for this sort of thing
https://mf.mattstudios.me/triumph-gui/introduction

makes things 100 times easier

To answer your question otherwise, you would wanna look for InventoryClickEvent, check if its the right inventory by name or smth and then handle your options

it will get complex quite quick which is why i would just use the library

[spiral prairie]

sus

[prisma briar]

Umm, I have installed XAMPP with PHP 8.1.4 but when I check my php version using php -v the version is still 8.0.3, it should be 8.1.4. I uninstalled XAMPP that were using PHP 8.0.3 and I install it again with the newest PHP version.

[shell moon]

i installed xampp 4 or 5 years ago, never updated it. still working

[prisma briar]

Some of my project require newest version of PHP and I have tried to only update the php but I ran into some errors and then I decided to reinstall the xampp.

my understanding of suspend fun was that it would wait, but intellij is telling me i dont need suspend

[brittle thunder]

It waits with both suspend and without

What suspend does it lets kotlin break down the method call to call the continuation from its result rather than blocking the current thread

Reduces chances of task starvation

[pearl topaz]

i read that i'm not meant to mark it as suspend unless forced to, so best to remove that and keep the rest as is?

i wasn't sure if it's a good idea to have a coroutine inside each of these that deals with the redis

probably not necessary right

[brittle thunder]

suspend ussually means you are performing some operation with idle time such as IO

[leaden sinew]

That’s unnecessary. I would go with try {} catch (Exception whoCares) {}

[pearl topaz]

it's too granular and descriptive?

[leaden sinew]

My way?

[pearl topaz]

no what i did

[leaden sinew]

How are messages valued?

[lyric gyro]

so true

[limber lagoon]

So I'm looking through the jda docs right

[lyric gyro]

so true

[hushed badge]

right

[lyric gyro]

left

[limber lagoon]

And I'm trying to get some slash commands running, and I see that you need to add jda.upsertCommand("ping", "Calculate ping of the bot").queue(); in your main method for it to work. So I'm wondering if the method was changed or smth

My bad I was caught up in a convo didn't get to finish

Since I can't use that method

Doesn't seem to be recognized

[dusky harness]

🤔 interesting, are you sure jda is a JDA instance (and other JDA methods show)? and that you're using the latest version? (4.4.0_352 or 5.0.0-alpha.9 if you're on v5)

[limber lagoon]

Ah, you know that would explain it. I'd need to create a JDA instance, but what should I initialize it to?

I already have a JDABuilder atm

[dusky harness]

wdym?

[limber lagoon]

I don't have a JDA instance atm, the code I pasted above was right from the docs

[dusky harness]

JDABuilder#build

[limber lagoon]

I mistaked their jda for a JDABuilder

[limber lagoon]

wym?

[dusky harness]

JDA jda = JDABuilder.createDefault("token").build();

[lyric gyro]

smh dkim

[dusky harness]

no i didn't forget

😃

[limber lagoon]

So I don't need a JDABuilder?

[dusky harness]

well

not a JDABuilder variable, no

[dusky harness]

u need to build it

as seen here

[limber lagoon]

Oh I didn't think it mattered

The order of building it, I mean

[dusky harness]

JDA jda = JDABuilder.createDefault(Constant.token) // should be TOKEN btw
              .setActivity(etc)
              .setStatus(etc)
              .build();
 ``` 😌

[limber lagoon]

Why should it be TOKEN

[dusky harness]

naming conventions

constants = UPPERCASE_WITH_UNDERSCORES

[limber lagoon]

Oh okay

I'll change that

Seems like there isn't a setActivity() method though

Wait

I spoke too soon

How can I find the name of the screen I'm on atm?

For termius

[dusky harness]

screen -ls - it should say Attached

[limber lagoon]

It says detached 🥲

I suppose it doesn't matter right? I was only trying to kill it

Well, how do I reattach the screen?

[dusky harness]

screen -R NAME -> Creates a new screen
screen -r NAME -> Resumes screen
screen -X -S NAME kill -> Delete screen
ctrl + a -> d -> Close screen

[limber lagoon]

I appreciate it, lemme copy paste this to the notepad 😎

This way, I won't ask the same question twice anymore

[lyric gyro]

ya bet

[limber lagoon]

Is killing a screen the same as deleting a screen?

[dusky harness]

yes

[limber lagoon]

If so, why did you recommend I use screen -S screen_name -X quit to kill a screen earlier?

[dusky harness]

uhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh

google 🥲

[limber lagoon]

🥲

So which one should I use? 😳

[dusky harness]

kill

[dusky harness]

this was from piggy

i think

[limber lagoon]

ah

well ok I'll use the kill one

It seems the kill one worked

[dusky harness]

nice

[limber lagoon]

[somber gale]

I'm quite inexperienced with Gson, so excuse if this is a stupid question, but how would a Java class need to look like if I want to deserialize this JSON input to one?

{
  "file_version": 1,
  "entry_1": {
    "major": "1.x",
    "version": "1.0.0"
  },
  "entry_2": {
    "major": "1.x",
    "version": "1.1.0"
  },
  "entry_3": {
    "major": "2.x",
    "version": "2.0.0"
  }
}

Some notes:

• entry_n can be any String, not just entry_n
• There can be any amount of entry_n entries in the JSON.
• file_version will always be named like that and always has a whole number (no decimals).
• major and version will always return String and will always be named like this.

So... Does Gson allow this kind of deserialization?

[dusty frost]

probably need to add an array for the entries

you have to know the schema you want to deserialize

so it would look like json { "file_version": 1, "entries": [ "entry_1": { "major": "1.x", "version": "1.0.0" }, "entry_2": { "major": "1.x", "version": "1.1.0" }, "entry_3": { "major": "2.x", "version": "2.0.0" } ] }

then you would need an object for entries

[lyric gyro]

err, for the entries just

"entries": [
  {
    "major": "...",
    "version": "..."
  },
  {
    ...
  }
]

otherwise it would need to be an object

[hoary scarab]

I think he wants the class structure to convert from gson to a class (and back).

[lyric gyro]

yeah but if you have each entry separately rather than in an array then you would need

class Thing {
  int fileVersion;
  Version entry1;
  Version entry2;
  Version entry3;
  Version entry3;
  ...
}

one class for each # of entries

[hoary scarab]

Or a map

[lyric gyro]

Yeah, bottom line is they need to be in a collection of sorts

[hoary scarab]

public class <class> {
    int fileVersion;
    Map<String, ObjectClass> entries;
}

public class ObjectClass {
    String major;
    String version;
}
``` or something.

I want to rotate a shape made from particles, in this case a double helix. I have the list of vectors representing the helix, and it works fine. However, I want it to point in the direction the player is looking. I do this by getting the players yaw and pitch and feed it into this rotate function. All input values are correct, however my math is so off, I tried following a guide but it did not go any better. The only thing that actually works is the pitch while facing south. I spawn the particles like this:

World w = player.getWorld();
for (Vector v : shape.getVectors()) {
w.spawnParticle(Particle.SCRAPE, location.add(v.getX(), v.getY(), v.getZ()), 10);
  //Revert back to the original location values
  location.subtract(v.getX(), v.getY(), v.getZ());
}

Here is my code for rotating the helix: https://paste.helpch.at/terepasufu.cpp
The helix is pre-calculated and stored in HELIX.getShape()

I copied parts of my actual code to the paste as I have a lot more and only need help with this part and want to keep the code here to a minimum. So if there are any misspelled variable names or missing parenthesis, that is why. The other code does not interfere with this in any way and only handles other shapes and their parameters.

hello ! how do I run a MySql query to find if a column contains a character string.

Like this:

If Swaford_ exist in column "Owner" in table "Town"

I tried that :
"SELECT * FROM town WHERE owner LIKE '"+ sender.getName()+ "'", "owner"

public void readData(String sqlRequest, String getResultString){
        try {

            Connection con = getConnection();

            assert con != null;
            PreparedStatement statement = con.prepareStatement(sqlRequest);

            ResultSet result = statement.executeQuery();

            while (result.next()){
                System.out.println(result.getString(getResultString));
            }

        }catch (Exception e){System.out.println(e);}
    }

I tried

dosen't work

hey so im currently working on creating a prefix plugin for my server i have textComponents working however i cant seem to workout how to remove the default username from the chat messages, how would i do this?

[brave swan]

Thanks, i look at your code and i think it's good but i've got an error

" foreach not applicable to type '[e-mail] Map<java.lang.Character,org.bukkit.inventory.ItemStack>' "

[hoary scarab]

I don't have an IDE open adjust the code accordingly.

Also add a null check before setting the item.

[icy shadow]

.entrySet()

[hoary scarab]

^^^

[brave swan]

Owww that work but i've got an another problem now items are not in order

[hoary scarab]

Also let me see your code

[brave swan]

https://imgur.com/OlMDNIL.png

[hoary scarab]

if slot++; is in the null check take it out.

Debug the ingredientmap. I thought it had a char for every slot.

[brave swan]

Sorry but i don't know how can i debug the ingredientmap...

[hoary scarab]

just add a message output in the for loop and as the string put the key and value.

[brave swan]

player.sendMessage(entry + " : " + shaped.getIngredientMap().entrySet());

Like this ?

[hoary scarab]

nope entry.getKey() + " | " + entry.getValue()

[brave swan]

Ok sorry to take your time

https://imgur.com/a/7qOOyNA.png

[hoary scarab]

Let me see the code with the debug

[brave swan]

https://imgur.com/MD7IUQJ.png

[hoary scarab]

add slot to the debug

[brave swan]

https://imgur.com/2kLRHAw.png

[hoary scarab]

put the debug before slot++

[brave swan]

https://imgur.com/cs6GOT6.png

[hoary scarab]

change int slot = 0 to 1

slot 0 is result mybad

[brave swan]

OWWWWW YES

Thanks

it work

You're the king

I love you

[hoary scarab]

Also there can be multiple recipes for the same itemstack so when you want you can animate the recipe. (I think essentials does this with /recipe)

[brave swan]

Yes good idea but normally i just use this GUI to see my item's craft, enchanting table was for example.

[brave swan]

I've got a problem

I've got multiple craft for cobblestone but with itemeta different

Cobblestone Tier I, Tier II, Tier III,... like compressed cobblestone

But

I think when i use Recipe recipe : Bukkit.getServer().getRecipesFor(item) , it's return the bad recipe

[hoary scarab]

You gotta account for that.

Modify your code anc check if its the recipe you want to display

[brave swan]

Sorry but i don't know how...

I've got an idea, can i just get the recipe with the Namespacedkey of the craft
https://imgur.com/h7J7JrI.png

[hoary scarab]

yeap but like I said the items can still have multiple recipes.

[brave swan]

Yes i know but that's not my actually problem, my problem is that when i want to see the craft of my cobblestone tier 1, the gui show me the craft of my cobblestone tier 4 because it is the last in my init method of craft.
https://imgur.com/oWXqA8Y.png

[hoary scarab]

Well then again... you have to code accordingly lol. Especially for custom items you have to check the recipe.

[brave swan]

Okay, big thanks

[hoary scarab]

hey, i am trying to detect a packet with protocollib but i get the following error: https://paste.razerstorm.be/iduwigopof.sql
(protocolLib is installed)
(this error pops up at startup/reload)
This is the code i tried (in the onEnable):

        ProtocolManager manager = ProtocolLibrary.getProtocolManager();

        if(getServer().getPluginManager().getPlugin("ProtocolLib") != null ){
            manager.addPacketListener(new PacketAdapter(this, ListenerPriority.NORMAL, PacketType.Play.Client.POSITION) {
                @Override
                public void onPacketReceiving(PacketEvent e) {
                   //handlePing(e.getPacket().getServerPings().read(0));
                }
            });
        }else{
            getLogger().severe("ProtocolLib is niet geinstalleerd op deze server!");
        }```
And this is my gradle import:
```gradle
    maven {
        url = "https://repo.dmulloy2.net/repository/public/"
    }```
```gradle
    compileOnly 'com.comphenix.protocol:ProtocolLib:4.7.0'

anyone that knows how to solve the error?

[dense drift]

Is the plugin version 4.7.0?

[formal crane]

its was at 4.8.0 but after changing it its still the same error

Hi, I wanted to code a plugin which gives every player a random item which he has to collect to get a reward. So I made a hashmap<UUID, Material> but every time I get to the point if(forceItem.containsKey(uuid)) it doesn´t do the rest of the event though it has my UUID with a random material Saved in the hashmap

https://paste.helpch.at/ohixifolez.java

[grim oasis]

Have you tried any debug messages?

[quaint skiff]

Yes because of that I know which line of code the problem is

[grim oasis]

so let's add some more

logger forceItem.containsKey(uuid)
loop map and log each uuid
log uuid

Does it proceed to if(item != null)?

[quaint skiff]

no it only goes till if(forceItem.containsKey(uuid))

[grim oasis]

okay, so try logging those 3 things i listed

see what they're saying

[quaint skiff]

what do you mean with logger forceItem.containsKey(uuid)? like after the if?

[grim oasis]

log it

log all those values

Bukkit.getLogger().info(forceItem.containsKey(uuid)+"");

or however you want to do your debug message

[grim oasis]

should be false based on previous debugging, but always good to see your values

[quaint skiff]

that is false the other 2 didnt send anything

[grim oasis]

wym

like, blank like?

null?

[quaint skiff]

no there just wasnt a message

[grim oasis]

where did you put them

[grim oasis]

Try logging the uuid instead

and maybe log the player

p.sendMessage(uuid); not even this sent to the player?

[quaint skiff]

it didnt but now it worked

[grim oasis]

ah

and are you sure you set the item in the map

how did you do that?

oh i see the command, did you debug that?

[quaint skiff]

Yes Java public void setForceItem(Player p) { setForbidden(forbidden); List<Material> items = new ArrayList(Arrays.asList(Material.values())); items.removeIf((material) -> {return !material.isItem();}); items.removeIf((material) -> {return forbidden.contains(material);}); int randomNumber = random.nextInt(items.size()); Material mat = items.get(randomNumber); forceItem.put(p.getUniqueId(), mat); p.sendMessage("§4Manhunt §8| §7" + mat); p.sendMessage(forceItem.toString()); if(p.getInventory().contains(mat)) { giveReward(p); }

[grim oasis]

try debugging the command and/or the setForceItem method

[quaint skiff]

setForceItem is already debugged because of p.sendMessage("§4Manhunt §8| §7" + mat); right?

[grim oasis]

and you get that message when you run the command?

[quaint skiff]

yes

[grim oasis]

instead of the forceitem.tostring try looping the keyset

log that and see

because that would be right after adding it...

[quaint skiff]

I am the only one added so its only one uuid

[grim oasis]

ok wait

we're missing a message here I realize

we should have player uuid:
forceitems uuids:
player:
contains:

[grim oasis]

so either forceitem is empty here

or we missed somethin

[quaint skiff]

yeah because i only wrote the command and not did the event

[grim oasis]

no, here

[grim oasis]

What is the code for this

is command just the label?

[quaint skiff]

            Bukkit.getLogger().info(uuid + "");
        }```

[quaint skiff]

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

            Bukkit.getLogger().info("command");

brother

wot

somebody explain this witchcraft?

[queen plank]

Wait, this public void setForceItem(Player p) and public HashMap<UUID, Material> forceItem = new HashMap<>(); are both non static. Are you making a new object every time you add a player?

Might that be why?

[grim oasis]

he never makes a new map though that I see

[queen plank]

Adding to the Sensaicraft discussion

[grim oasis]

and in the command you can see the value(s)

[queen plank]

Well i creates a new one with every object

and if they make one every time they add a player

it wont add

to the same map as the listener one

try making them static

[grim oasis]

i might be missing something, but ya give that a go

see what happens

[queen plank]

I cant come up with anything better

[quaint skiff]

ok i will try it

[hoary scarab]

actually it doesn't output when I type the aliases

[grim oasis]

I don't get why you see the values in the onCommand method though

[grim oasis]

aha

does it run at all

the executor

[hoary scarab]

nope

[grim oasis]

hmm, I wonder if you have to update something else after setting aliases. commands are confusing to me

[hoary scarab]

If I add the aliases directly to the plugin.yml they work.

[quaint skiff]

if(forceItem.containsKey(uuid)) worked now but it still didn´t gave a reward so if (inv != null && inv.contains(getForceItem)) { giveReward(p); p.sendMessage("reward"); } didn´t work

[queen plank]

Hold on, I'll try re-write it. spoon feed :>

[grim oasis]

ok well that's progress

still confused sadly

[hoary scarab]

try containsAtleast(getForceItem, 1); Otherwise debug the item and the if statement

[icy thistle]

when I download source code for a plugin project how do I know how to compile it so it works the way intended

same for java version used

[hoary scarab]

So it looks like I need to mess with the command map because setAliases doesn't do anything after registering the command🤦

[grim oasis]

ya... figured it was something weird like that

[queen plank]

Try this, I have not tested it so unsure if it works as you want it to, also I don't have your other classes like OpLoot. But give it a go https://paste.helpch.at/vorikelaye.java

Error:

Line of the issue:
```JAVA
public boolean isOwnerOfClan(UUID uuid, @Nullable String clanId) {
  return db.getString("clans." + clanId + ".owner").equals(uuid.toString());
}

specifically, the issue seems to be uuid.toString()?

like, is it normal that I can't cast it to a string?

[queen plank]

UUID.toString() works fine. There should be no problems with it. I can't see anything wrong

You can't cast it though

This UUID.toString() is fine, (String) UUID is not

[broken elbow]

aby chance your db stores it as a UUID instead of a String?

[worn jasper]

that's a quite big change yes.

okay no

it's a string

String.valueOf(uuid) that's how I store it

unless... okay found the issue

[tight junco]

why do you seperate the string

i assume just for code formatting

[hoary citrus]

yea

[tight junco]

Your issue is likely that IGNORE INFO part

You could likely just do INSERT INTO linkedaccounts

[sand ermine]

Do you mean INSERT INFO in the

Instead of INSERT INTO

[tight junco]

this is what i do to recreate your table and it works

so INSERT INTO linkedaccounts (name, uuid, token) VALUES (?, ?, ?)

[hoary citrus]

oh im an idiot

this is my first time using SQL and I read INTO as INFO

my bad xd

[sand ermine]

Also how did you uh get to see the table like that

[hoary citrus]

yea what app is that

[tight junco]

when testing SQL stuff i use https://sqliteonline.com

my dark mode extension is making the colours kinda wonk but yeah i use it a ton

[sand ermine]

Looks great, ty

[twilit delta]

Okay;

im learning NMS and I found this example on the web, and I changed some stuff.

        this.r(false);
        this.n(true);
        this.a(new ChatComponentText(ChatColor.GREEN + "MyEntity"));
    }
}

First, what do I return?
Second, when I call it up, do I do this?

connection.a(new PacketPlayOutSpawnEntity(BigWither));

[hoary citrus]

again with the SQL nonsense

"PreparedStatement ps = plugin.sql.getConnection().prepareStatement("SELECT name FROM linkedaccounts where token=?");"

this line is producing a nullpointerexception. I already checked, and the argument I giving for token isn't null.

[hoary citrus]

where wasnt capital

xd

wawit nvm

Either plugin, sql, or connection is null

ah I think plugin is null

yea it is but idk how to make it not null

You're passing Array<MyObject>::class.java, testFunction expects a T instance, not a Class<T>

[formal crane]

Okay so i tried adding an nbt tag to a entity with this code:

            Entity huisdier = p.getWorld().spawnEntity(p.getLocation(), EntityType.WOLF);
            huisdier.setCustomNameVisible(true);
            huisdier.setCustomName(Util.chat("&cGerda"));
            NBTEditor.set( huisdier, "hond", "ddgpets" );```
but it won't work, this is the code where i check for the nbt:
```java
        if(NBTEditor.contains(e.getEntity(), "ddgpets")) {
            Bukkit.broadcastMessage("Test 2");
            e.setCancelled(true);
        }

So how would I pass it a T instancE? I /havent used generics before lol

testFunction(arrayOf<MyObject>()) or however you create arrays in kotlin

i need help with some batch, for some reason setlocal EnableDelayedExpansion is making it so that when the 2nd call command is ran, it goes back to the directory where the called file is:
Specific Export.bat:bat call backend\specific.bat call "%~dp0backend\export.bat" false
specific.bat: https://paste.srnyx.xyz/acojemavol.bat

example: specific.bat makes it go to modpack/OO/1.18.2. then, when it does call "%~dp0backend\export.bat" false, it goes back to modpack/Tools (which is where Specific Export.bat is)

when i remove setlocal EnableDelayedExpansion in specific.bat it works, but i need it in order for other parts of the script to work

ok i think i fixed it
i had to put setlocal EnableDelayedExpansion in Specifix Export.bat (before call backend\specific.bat) for some reason

Could anyone help me so im Using Deluxechat premium But i use it in a faction server but now the ranks dont have the right color and YOu cant see the faction name anymore?

[spiral prairie]

spigot

yes

[restive isle]

how?

[spiral prairie]

get the item

change item meta

set item

[restive isle]

thanks can i ask you questions if i cant figure it out?

[spiral prairie]

sure

[restive isle]

do you have code where you did this?

[spiral prairie]

player.getInventory.getItem or something like this

[restive isle]

im really stuck this is what I got rn i dont know what to do and i cant find good info on internet

Item meta = player.getInventory().getItem(Material.GOLD_BLOCK);

[spiral prairie]

that wont work on every end lol

you might just want to take a look at the documentation

[restive isle]

ItemStack itemStack = new ItemStack(Material.IRON_SWORD); this doesnt give me a iron sword? what did i do wrong

[lyric gyro]

not sharing the rest of the code

[restive isle]

lol

its on player movement

@EventHandler
public void onMove(PlayerMoveEvent e) {
ItemStack itemStack = new ItemStack(Material.IRON_SWORD);
}

[lyric gyro]

Well, you are creating an iron sword item, but you aren't doing anything with it

[restive isle]

so how would i do that?

giving the player that item\

[lyric gyro]

If you want to add it to the player's inventory, get the player from the event, get their inventory and add the item, should be something like so event. getPlayer().getInventory().addItem(item)
Be aware that the move event is called on every single tiny movement so you're going to fill that quickly

[restive isle]

@EventHandler
    public void onMove(PlayerMoveEvent e) {
        

        ItemStack itemStack = new ItemStack(Material.GOLD_BLOCK);


        ItemMeta meta = itemStack.getItemMeta();

        meta.setDisplayName(MyFirstPlugin.balance.toString());
        meta.setLore(Arrays.asList("line 1", "line2"));

        itemStack.setItemMeta(meta);
        if (balance_int == 1) {
            e.getPlayer().getInventory().addItem(itemStack);
            balance_int = balance_int-1;
        }


    }

can you run the server again to get the updated error

ooh, but I see your issue actually

It looks like you get the item meta of a fresh itemstack

Which, the item stack probably won't have

[restive isle]

so what should i do?

[grim oasis]

fs do this

and then we can go from there

cause I could be right, could be wrong

could be this MyFirstPlugin.balance.toString()

im a beginer

ye 😁

meta.setDisplayName(MyFirstPlugin.balance.toString());
it allready is

[grim oasis]

what is?

[restive isle]

oh nvm

MyFirstPlugin.balance.toString() what should this be?

then?

[grim oasis]

Well you never initialized balance

[proud pebble]

looks like balance is uninitalized, no value is ever set.

[grim oasis]

if balance was an int it would initialize as 0 (instead of Integer)

[proud pebble]

balance is set as the object form of integer instead of the keyword

weird

[grim oasis]

ya, it's a bit odd

[proud pebble]

also static abuse very much

[grim oasis]

but, beginner code

[restive isle]

what do you mean by intialize

[grim oasis]

public static Integer amount = 1;

you initialized amount here to 1

public static Integer balance;

balance is never initialized

[restive isle]

oh

[proud pebble]

same with playerWhoBoughtTheShop

[grim oasis]

basically, you defined balance as an Integer type, but never initialized the value

[restive isle]

oh i understand

yes it works!

[proud pebble]

also balance is global

is that intensional?

[restive isle]

what do you mean with global?

[proud pebble]

your balance variable in your main class

[restive isle]

oh ye

idrk what im doing tbh

[proud pebble]

i can see that

[restive isle]

but its fine rigth?

[proud pebble]

¯_(ツ)_/¯

[round sail]

If you’re happy with any outcome then it’s fine 😝

[restive isle]

so now i wanna change the meta of the item while your holding it

how do i do that>

[warm steppe]

ItemStack#getItemMeta()

iirc

[proud pebble]

ItemMeta meta = item.getItemMeta();
meta.whatever
meta.somethingelse
item.setItemMeta(meta);

[kind granite]

null check it first

bukkit is special like that

[restive isle]

what should be on whatever or on something else

like should i deifine the meta

[proud pebble]

the meta is already defined since you are doing item.getItemMeta()

whatever and somethingelse is just placeholders for whatever meta you want to modify

[restive isle]

ItemStack itemStack = new ItemStack(Material.GOLD_BLOCK);

    ItemMeta meta = itemStack.getItemMeta();

    meta.setDisplayName(MyFirstPlugin.balance.toString());
    meta.setLore(Arrays.asList("line 1", "line2"));

    itemStack.setItemMeta(meta);
    if (balance_int == 1) {
        e.getPlayer().getInventory().addItem(itemStack);
        balance_int = balance_int-1;
    }

where should i put it? after the player got the item?

i really dont understand this could you just put it in for me?

[proud pebble]

i dont know where you even want this

[restive isle]

uhg

idk?

so i want that the name of the item changes in your inveroty

and I firstly did it by clearing the item and then replacing it

but thats not clean cz you will see the item popping out and in to your invertory first of all

[proud pebble]

then just set the slot

instead of removing it first

you dont have to remove it

[restive isle]

how do i do that>

[proud pebble]

p.getinventory.setitem(slot,itemstack);

[restive isle]

ty

what is slot 1 etc?

[proud pebble]

[kind granite]

are you using the java plugin

[worn jasper]

uhm is this params supposed to be the identifier?

[pulsar ferry]

I'm assuming it's because of that project block down there, what are you even doing there?
I have never seen that being used like that, but anyways, the project would be considered differently, so the plugin you're applying above doesn't apply to the specific project

That is very cursed

[dense drift]

yes

[wintry grove]

I think I forgot the java plugin lmao

[pulsar ferry]

For real though, what are you doing with that project block down there?

[wintry grove]

I dont know much of the kotlin DSL, but my mind thought that would make the module depend on that

probably wrong

[pulsar ferry]

Well if you want a module to depend on those you'd create the module and put that inside its own build.gradle

[wintry grove]

yeah ty

[cerulean birch]

does the BukkitScheduler run asynchronous tasks in order, or is it unpredictable?
i.e if I run task A async, then run task B async, can I expect A to run and finish before B is started? or should I make my own single thread executor instead

[kind granite]

are they not unpredictable by their asynchronous nature

[cerulean birch]

i guess i'm asking if it uses a single thread to execute tasks async or several

[dense drift]

Yes

[cerulean birch]

you can still have tasks run in order asynchronously, if they're all run on the same separate thread

[vestal forge]

you can look at implementation

but its probably using some threadpool

or just do

runAsync{
//sometask

//someothertaskthatneedstobecalledasync()




}

[vestal forge]

where thread pool is equivalent to your cpu cores number

Damn. The project owner is using maven so I can't use it

[01:38:32] [Server thread/ERROR]: Could not load 'plugins/Core.jar' in folder 'plugins'
org.bukkit.plugin.InvalidPluginException: java.lang.UnsupportedClassVersionError: me/fiftyone/core/Main has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 55.0```
Tried doing what people said online about changing compiler compliance level but still nothing changes throws the same error

[prisma briar]

Change the java version of your server to at least the same version as the plugin or above.

[barren ore]

Issue is when I change java version of my Linux server from 11 to 17 so it can run the "file version 61.0" my server no longer wants to start no logs or anything

I am running 1.16.5

[prisma briar]

Are you on shared hosting?

[barren ore]

Don't think so I have a VPS server bought from OVH

I have Java 11 and Java 17 installed onto it

And I can change the versions using sudo update-alternatives --config java

If i change the version to 11 the server starts up perfectly fine but throws that error that I showed above

If I switch to 17 to try make that error go away my server doesnt start at all

[prisma briar]

Well I don't know the details on configuring java version on linux, but usually you only want to change the java version on the startup parameters of the minecraft server.

[barren ore]

How do i change those?

Whats the parameters

You mean something like : "C:\Program Files\Java\jre1.8.0_311\bin\javaw.exe" -Xmx2048M -Xms2048M -jar forge-1.16.5-36.2.20.jar
pause

?

[prisma briar]

To start the minecraft server do you have to run something like java -jar server.jar or something.

Yeah that part

Change this "C:\Program Files\Java\jre1.8.0_311\bin\javaw.exe" to your java 17 path

And use java.exe, not javaw.exe

[barren ore]

Could it be because the Java 17 isnt a jdk?

I have just noticed my Java 11 is like this /usr/lib/jvm/java-11-openjdk-amd64/bin/java

The Java 17 appears to be like this /usr/lib/jvm/java-17-oracle/bin/java

Says oracle

[prisma briar]

Well that depends on your installation folder.

I download my java 17 from this site https://adoptium.net/

[barren ore]

Yes it's different on linux however, im not running my server locally unfortunately :/

Hmm ok 1.16.5 will not even run on java 17 so now i'm completely confused how to run this plugin now :/

[dusty frost]

yes it will lol

[barren ore]

idk then it just won't let me start my server using Java 17 is there any other way to just make the plugin use the class version 55.0

[winged pebble]

55 is java 11 iirc

You could set the target of your project to 11

But for future reference, you have to run buildtools with the version of java that you are wanting

That will give you the server jar in the versino that you need

[barren ore]

Ah my issue might be that I didnt use BuildTools

[dusty frost]

or just use Paper lmao

[prisma briar]

Is running a minecraft server on linux vps are the same as running minecraft server on your computer, or am I mistaken?

[winged pebble]

For a vps you're usually ssh'ing in

Which means you don't have a gui besides the terminal

[torpid raft]

fundamentally it's the same

but yeah ^ managing it is very different on windows vs linux

you will also want to expose your server to the public when it's on your vps while you might not need to on your pc if you only want to run it locally

[prisma briar]

Ah okay, but to transfer file you usually use ftp client right?

And to start the minecraft server you'll run the command just like in Windows localhost

[hoary citrus]

so I've created a discord bot inside of my plugin, and I need to get the plugin instance for my sql instance.

However, whenever I do the usual MainClass plugin;

blah blah
it returns null

DiscordLinkRoles plugin;
    public DiscordLinkCommand(DiscordLinkRoles plugin) {
        this.plugin = plugin;
    }```

I need to access "plugin.sql"
that being public MySQL sql;

[winged pebble]

What returns null?

The plugin arg?

[hoary citrus]

indeed

[winged pebble]

How are you initializing it

[hoary citrus]

initializing the "plugin" arg?

I showed it above

[winged pebble]

No, the class

Show me where you're instatiating it

[hoary citrus]

wdym. sorry if I seem dumb, its cuz I am but its also 5am

[winged pebble]

Where are you calling the constructor for DiscordLinkCommand

[hoary citrus]

ohh

in my Bot.java class

bot = JDABuilder.createDefault(token)
                .addEventListeners(new DiscordLinkCommand(plugin))
                .build();```

the error says its occuring on this line

PreparedStatement ps = plugin.sql.getConnection().prepareStatement("SELECT name FROM linkedaccounts WHERE token=?");```

and so I checked if plugin was null with a simple if(plugin == null) {
print that its null }

and it said it was null

[winged pebble]

Show me where that plugin var gets initialized

[sand ermine]

@hoary citrus

getCommand("worldinfo").setExecutor(new WorldCommand(this));

like this bit i think he means

[hoary citrus]

well thats what I showed, I also showed where plugin gets initialized in the event listener

[winged pebble]

No, that's a different plugin variable

You should me inside the DiscordLinkCommand class

[hoary citrus]

I showed you the one inside the discordlinkcommand class

[winged pebble]

But where in the class that does this is plugin initialized

[hoary citrus]

DiscordLinkRoles plugin;
    public DiscordLinkCommand(DiscordLinkRoles plugin) {
        this.plugin = plugin;
    }```

and my bot class, whcih is the one with the code you just replied too,

initializes it like so

public Bot(DiscordLinkRoles plugin) {
        Bot.plugin = plugin;
    }```

[winged pebble]

Show your Bot class

The whole thing

[hoary citrus]

public static JDA bot;
    public static DiscordLinkRoles plugin;

    public Bot(DiscordLinkRoles plugin) {
        Bot.plugin = plugin;
    }

    

    public static void discordBot() throws LoginException {
        
        bot = JDABuilder.createDefault(token)
                .addEventListeners(new DiscordLinkCommand(plugin))
                .build();

    }```

[winged pebble]

And where is Bot.discordBot() called?

[hoary citrus]

in my main class

[winged pebble]

Show it

[hoary citrus]

ry {
            Bot.discordBot();
        } catch (LoginException e) {
            e.printStackTrace();
        }```

[winged pebble]

Show more

[hoary citrus]

apparently I cant

public static MySQL sql;
    public SQLGetter data;

    @Override
    public void onEnable() {



        sql = new MySQL();
        this.data = new SQLGetter(this);

        try {
            sql.connect();
        } catch(ClassNotFoundException | SQLException e) {
            Bukkit.getLogger().info("DB ISNT CONNECTED idiot!");
        }

        if(sql.isConnected()) {
            Bukkit.getLogger().info("DB IS CONNECTED. GOOD JOB");
            data.createTable();
        }


        getCommand("test").setExecutor(new TestCommand());
        getCommand("linkaccount").setExecutor(new DiscordLink());


        try {
            Bot.discordBot();
        } catch (LoginException e) {
            e.printStackTrace();
        }

    }```

[winged pebble]

You're never calling the constructor of Bot

So Bot.plugin is never initialized

[hoary citrus]

but it isnt needed inside bot

its needed inside discordlinkcommand

[winged pebble]

Yeah I know

But you're never passing the plugin instance through

[hoary citrus]

where do I need to pass it through?

[winged pebble]

So Bot.plugin never receives an instance of your plugin

[hoary citrus]

I just made the sql instance in my main class static

and made a local variable in the event listener

fixes the issue :p

[winged pebble]

You could have just passed the plugin instance through Bot's static method too

Would have been better probably

Too much static going on

Online Courses:
Online courses are also great for learning java. Some websites that offer them are:

• Coursera - Free unless you want a certificate
• PluralSight - Great courses from what I've seen. Mostly Paid
• Udemy - Never used them myself but they seem to all or at least most be paid.
  My first ever course was one from Coursera. - I can say it was pretty good at introducing me to the programming world as a whole not just java.

Oracle Docs:
Oracle docs can help a lot at learning and understanding java:

• Start with this,
• Breeze through this (skipping stuff that doesn't seem relevant like bitwise operators),
• Hit this.
  They're the first three from this larger thing which you should definitely go through overall. But those three should be enough for slightly better understanding of what is happening here without feeling like a huge time sink.
  That one is a small part of this larger site wherein "Essential Java Classes" and "Collections" also have good useful stuff

Other services:
Some other cool services that will help you learn java are:

• SoloLearn
• W3Schools
• JetBrains Academy

As you can see there are plenty of good ways to learn as long as you're willing to invest the time. Have fun learning!

[graceful juniper]

How does someone create a new itemmeta for an item if getItemMeta() returns null

[neon wren]

Can you explain what you are doing in code or put it in a paste?

[graceful juniper]

Essentially, when the player picks up an item, i want to edit the itemmeta. However, trying to do so will spit out a nullpointer, halting the entire process of editting the itemmeta and giving the item to the player.

[neon wren]

@graceful juniper So I presume you are using 1.18, and using the event EntityPickUpItemEvent (https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/entity/EntityPickupItemEvent.html#getItem()).

I can't really write up a example right now, so hopefully someone else can help but that event should work fine for getting a item's meta but you'd just need to make sure it's the correct item and entity.

[inner jolt]

ItemMeta meta = new ItemStack(Material.IRON_SWORD).getItemMeta()```
and then from there you can edit meta to whatever you want it to be, and then set the desired item's ItemMeta to the variable.

not sure if this is what you're looking for

[graceful juniper]

Sorry I didnt specify, I am using 1.16.5 (im comfortable with this and most of my personal projects are on this version).
I am indeed using EntityPickUpItemEvent which allows me to grab the material and use my own extension of ItemStack.

Currently my personal extension of ItemStack is just exactly what ItemStack does but does it's own code to add information into the item via the ItemMeta.

This is what my extension does. It only does this.

  private void init() {

        ItemMeta meta = getItemMeta();

        meta.setDisplayName(material.getRarity().getColour() + material.getName());

        List<String> lore = new ArrayList<>();

        lore.add(" ");
        lore.add(material.getRarity().getColour() + material.getRarity().getName());

        meta.setLore(lore);

        meta.getPersistentDataContainer().set(material.getKey(), PersistentDataType.STRING, material.getKey().getKey());
        meta.getPersistentDataContainer().set(material.getRarity().getKey(), PersistentDataType.STRING, material.getRarity().getKey().getKey());

        setItemMeta(meta);

    }

Removing this piece of code makes it work perfectly. It's just the ItemMeta which isn't correct

[inner jolt]

replace ItemMeta meta = getItemMeta(); with

if (this.hasItemMeta()) {
  ItemMeta meta = getItemMeta();
} else {
  ItemMeta meta = new ItemStack(Material.IRON_SWORD).getItemMeta();
}

this way you're checking if the item has meta, and if it doesn't then you're creating a new one

[graceful juniper]

I will have a go, I will reply further if I have more issues. Thank you :D

[inner jolt]

no problem!

[graceful juniper]

@inner jolt
Quick question
Would this essentially work as the same:

ItemMeta meta = hasItemMeta() ? getItemMeta() : new ItemStack(this.material.getMaterial()).getItemMeta();

[inner jolt]

Yeah pretty much

i don't think that a new itemstack with the material is guaranteed to have an itemmeta though

which is why i normally generate it using an iron sword

[graceful juniper]

Are you able to use itemmeta from another type of material?

[inner jolt]

I've done it in the past without any issues, but I'm not sure if it's the best solution

[graceful juniper]

Alright

All works now, tysm @inner jolt

[inner jolt]

Awesome! Good luck on your code 👍

[graceful juniper]

You too!

how important is the single responsibility principle? for example I have a method deserialiseAndSet(value: String) which takes a serialised value for the object and then updates the value of the object to that value

if it's important, this is a guaranteed method provided by the interface that all objects of this type implement

there's no real application for just a deserialise() method outside of this, and it would also mean I'd need to parameterise my interface w generics since the return value would have to be different for each class

[icy shadow]

the design certainly won't scale very well

and it is a bad practice to be bundling that much logic together

However if it's not public code then you can take the risk of later suffering if you're feeling lazy

If you intend to publish / share the code you should absolutely be following the design principles more strictly

[lyric gyro]

daarom boys

inshallah

[pearl topaz]

in what way?

I'm struggling to figure out a cleaner way of doing it

imo it feels better to couple the logic rather than parameterise the interface

especially when a lot of the time that parameter will just be *

[icy shadow]

you're coupling deserialization logic with object mapping, and whatever else the target class does - the better option imo would be a Deserializer interface that can generate a Map, then you do object mapping, and then all that logic is done somewhere away from the models in a service class or something

But I don't know the full context so that might be completely inapplicable

[lyric gyro]

yeah well I think you should consider using a reflective inverted bimap implementation as your current system should declare an interface with a more clearly defined contract and you should really be splitting your 4 line method into 8 different classes for the Single responsibility Liskov principle which you learn about in Section 7 of Advanced Java course

[icy shadow]

True!

[pearl topaz]

I'm confused what Map I would be generating?

[icy shadow]

To represent the deserialized output

Which can then be loaded into the object attributes

[sterile hinge]

This tbh

[icy shadow]

It is quite hard to give proper architectural advice when all the information I have is 1 method though

[pearl topaz]

I have classes that overload Mutable types like MutableLong, in order to set the value in a Redis DB whenever the underlying value of the mutable type is changed, e.g. I have a LongLogger.

these all implement the MyLogger interface which guarantees the deserialiseAndSet() method as well as serialise(). we're serialising to and from strings as that is what is stored in redis

I have an API that can update the value of any of these loggers by it's name. it accepts a serialised string. there's a map of them so I can just use the key to get the logger, and then since it's a map like Map<String, MyLogger> I can just do myLogger.deserialiseAndSet(value) without having to know what type of logger it is

the deserialised output is just of the type of the logger, e.g. Double for DoubleLogger

that's why I would have to parameterise the interface like MyLogger<T> so I can guarantee the method fun deserialise(value: String): T if I were to decouple the logic

Is it someone get memory leaks in IntelliJ IDEA 2021.3.2 when use suggestions with Material class (I have increasing ram several times)?

now it use 8Gb and it need even more (I have 55% more ram to use, but should not need all ram for it self).

[odd prawn]

lyam

no

[dense drift]

I know that you can make package private classes by declaring it without public, is there any way to make smth like "project private"? Meaning it can be accessed by classes from the current project but not other projects.

[lyric gyro]

Inshallah man, zeg je eerlijk

Wel firah 🔥

[hushed badge]

not in java no

[lyric gyro]

that's what java modules are for :)

[dense drift]

AH YES

[somber gale]

Oh how I HATE Gradle

this piece of shit seriously shouldn't be used at all

Never saw any software so bad with dependencies

[leaden sinew]

What the heck is that formatting

[dusky harness]

IntelliJ is the one that colors it tho

unless it's giving compilation errors

then u prob need to check build.gradle(.kts) 🙃

[lyric gyro]

fucking lmao

read guides and learn how to use tooling
ask for help with tooling
complain and blame tooling for user errors

[somber gale]

The build.gradle file is perfectly fine as I used that project like half a year ago and didn't change a thing

I never have those issues using maven, yet people always say Gradle is better

[lyric gyro]

guess what

because it is

ask for help, big boy

[somber gale]

I really don't care. The project is dead anyway

[winged pebble]

Apparently you do

[lyric gyro]

yeah it doesn't look like you don't care lol

[somber gale]

I just wanted to share my hate for Intelij + Gradle acting horrible

[lyric gyro]

gradle works perfectly fine if you know what you're doing

like, y'know, how everything is

[inner jolt]

@EventHandler
public void onInventoryClick(InventoryClickEvent e) {
    if (e.getView().getTitle().equals(ChatColor.AQUA + "Auction House")) e.setCancelled(true);
}

@EventHandler
public void onInventoryDrag(InventoryDragEvent e) {
    if (e.getView().getTitle().equals(ChatColor.AQUA + "Auction House")) e.setCancelled(true);
}

The player is able to use "F" in order to move the item from the inventory into their offhand. The item is duplicated, with one copy going into the Player's offhand and theo ther staying in the inventory. Is there a way to fix this?

[pulsar ferry]

If the player is in creative that is an issue, MC doesn't validate the inventory in creative, if they are in survival or adventure then the item is a ghost item and disappears after
And also, comparing inventory titles is not a good idea to verify if the inventory is the correct one

[inner jolt]

Ah alright, thank you

i've only been testing it in creative

What do you suggest for inventory verification?

[pulsar ferry]

Either comparing inventories directly or using a custom InventoryHolder

[inner jolt]

Got it, thank you

[dense drift]

from my understanding, the only broken part is the integration for groovy gradle, which sucks - but kts exist 😄

[hoary citrus]

do you learn all of this with practice or do you just read through the docs when you have time

[winged pebble]

Experience and practice

[warm steppe]

user problem

also tf is that formatting

[thorn cape]

Is there any way to get an item name like potion item names? Say like Potion of Swiftness etc.

Because I am trying to read potions from a file and don't know how I would set the name

ItemMeta#setDisplayname("§fPotion of Swiftness")

I belive thats client side

Iirc you can get it from the server, paper exposes it I think, spigot doesn't

[dense drift]

d;paper ItemMeta#getLocalizedName

[uneven lantern]

org.bukkit.inventory.meta.ItemMeta#getLocalizedName

@Deprecated @NotNull
@NotNull String getLocalizedName()```

Description:

Gets the localized display name that is set.

Plugins should check that hasLocalizedName() returns true before calling this method.

Deprecation Message:

Use displayName() and cast it to a TranslatableComponent. No longer used by the client.

Returns:

the localized name that is set

[pulsar ferry]

It could be

d;paper ItemStack#displayName

[uneven lantern]

org.bukkit.inventory.ItemStack#displayName

@NotNull
public Component displayName()```

Description:

Get the formatted display name of the ItemStack.

Returns:

display name of the ItemStack

Requested by: Matt • paper

[shell moon]

Wait, itemstack has setDisplayname?

wtf

wasnt it ItemMeta exclusive?

[somber gale]

I assume it's Paper

Tho, not a fan of the naming... ItemStack#displayName()

[lyric gyro]

ItemStack#displayName and ItemMeta#displayName return different components… whoever thought it was a good idea to name them the same thing needs to reevaluate their choices

[dense drift]

How come lol

[lyric gyro]

ItemMeta is basically the item's NBT, so that one returns the display.Name NBT path

[spiral prairie]

stoopid who did that

[lyric gyro]

ItemStack#displayName returns what the game uses for when like e.g. you kill someone with a renamed item, it puts it in [] (actually it puts the NBT display name as argument for a translation entry, that renders to []) and adds the item hover event

[lyric gyro]

The naming? Yes. The methods themselves? Not really

[spiral prairie]

who needs the ItemStack#displayName method?

[lyric gyro]

I've used it one time so there definitely is use for it

and that's the most useful alternative to "chat item" things like [i] or whatever

[spiral prairie]

ah

[lyric gyro]

it's quite niche still

[dense drift]

Lol

[lyric gyro]

"lol"?🤨

My IDE is telling me this new Random().nextDouble(someDouble); is not valid. Why?

[kind granite]

i dont know

whats it saying

[queen plank]

The method nextDouble() in the type Random is not applicable for the arguments (double)

[kind granite]

d;jdk Random#nextDouble

[uneven lantern]

java.util.random.RandomGenerator#nextDouble

default double nextDouble()```

Description:

Returns:

Requested by: __lucyy • jdk

[kind granite]

i mean

it doesn't take a parameter

[queen plank]

I find this tho double java.util.random.RandomGenerator.nextDouble(double bound). The description is: Returns a pseudorandomly chosen double value between zero(inclusive) and the specified bound (exclusive).

When I inspect it

[kind granite]

yeah that's what id expect

youre passing an argument that it's not expecting

[queen plank]

I meant that

I changed it

Sorry, did it wrong the first time

That is the reason I am confused. There is a function that takes in a double as a bound
