[supple elk]

the api would contain this

[glossy venture]

yeah

but how would you make it an enum

[supple elk]

then whomever was implementing could then create an enum?

[restive tangle]

Either way should work

[supple elk]

wait

[restive tangle]

In an API? Probably not

[supple elk]

I think it's a good idea to try and build my foundation as an API

[restive tangle]

For sure

[supple elk]

keeps it modular

[ivory sleet]

Feels like enum here would be way too inflexible, especially since you work with some sort of game type hierarchy

[supple elk]

yeah

[glossy venture]

yeah but idk how you would implement an enum

here

because GameType is abstract

[supple elk]

mhm

[ivory sleet]

if its an interface

[supple elk]

I'll do the registery thing

though on this

if I say registered "skywars", SkywarsFactory

then I got the GameType by id

I'd then have to cast it back to SkywarsFactory wouldn't I?

[glossy venture]

yeah but its useful to have the id stored in the game type too

[glossy venture]

you can do generics trick

[supple elk]

oh?

[glossy venture]

@SupressWarnings("unchecked")
public <T extends GameType> getType(String id) {
  return (T) typesById.get(id);
}

[supple elk]

where does the T come from?

[ivory sleet]

Feels like you want a type token as well then

[glossy venture]

from what you need

the compiler decides it

SkywarsGameType skywars = manager.getType("skywars");

now T is SkywarsGameType

[ivory sleet]

^ altho it becomes a little bit hard to keep track of the casts that way as you don't have anything that confirms it

[restive tangle]

That's pretty cool

[supple elk]

?

[glossy venture]

you need to add T after iut

[ivory sleet]

returns T as well

[glossy venture]

you havent specified the return type yet

[supple elk]

ah

wait

show?

[glossy venture]

you can also do

<T extends GameType<?>> T getType(String id, Class<T> tClass)
``` for explicit type specification

[supple elk]

oh right

oh my god that is so cool

I never knew you could do that

[glossy venture]

then getType("skywars", SkywarsGameType.class) will return SkywarsGameType

[supple elk]

yeah

duddee

that is sick

[sacred mountain]

YESSS just spent 2 hours coding a plugin and it worked first time

[ivory sleet]

noice

[sacred mountain]

actually now i can revise for more important tings

[noble lantern]

the cursed class

[sacred mountain]

whats cursed about it

not extending javaplugin?

[noble lantern]

indeed, not sure how i like it tbh

[restive tangle]

BurchAPI

Alhamdurillah

[sacred mountain]

my death messages plugin works

[torn shuttle]

it's as fun as it is a pain in the ass to remember the syntax for

oh

that was about the generics thing

[glossy venture]

why

you mean at GameManager

its not my design

the game type class is meant to be extended

oh yeah forgot abstract

[ivory sleet]

why tho

[sacred prairie]

Is there any way to detect if a falling block with the tag "beacon" droped as item?

[glossy venture]

i honestly wouldnt care it makes more sense than a random registry

having a GameManager with running games and game types makes more sense to me than some random Registry<GameType<?>>

and then a List<Game>

yeah it depends per person

[ivory sleet]

Id actually disagree to some extent there

[torn shuttle]

only the sith deal in absolutes

[ivory sleet]

lol

[torn shuttle]

sometimes you need a manager

most times you should avoid it

[glossy venture]

well for things like services its useful

some kind of ServiceManager

[ivory sleet]

I mean the best part about managers is the fact that they are very abstract

so it can serve as high abstraction layer point

where it delegates to registries, observers etc

[torn shuttle]

tastes like my MatchInstance class

[ivory sleet]

so like

you want the projectile to go thru blocks?

like ghosting them?

[lean gull]

anyone?

[ivory sleet]

oh idk

not without looking at nms

[lean gull]

i wanna set the ObjectID of the _id of a document in mongodb to a player UUID, idk how to elaborate

i was told it's a little too much for my small knowledge

i barely know what i'm doing

[supple elk]

😰

👀

[sage patio]

For disabling hitbox of an armor stand, setMarker() should be true or false?

[willow mortar]

Definitely move to Morphia. I was just using plain old Mongo and Morphia was a massive help: halves the amount of boilerplate code you have to write, avoids a load of NPEs - what's not to love? To set the ObjectID you can just use the @Id annotation on one of the entity fields.

[lean gull]

you just said a lot of things that i do not understand

[willow mortar]

Haha sorry :P

There are definitely tutorials somewhere that'll help, lemme find one

[sage patio]

?

[willow mortar]

https://morphia.dev/morphia/2.2/quicktour.html will help - MAKE SURE YOU SHADE THE MORPHIA & MONGODB DEPENDENCIES CORRECTLY! If you don't you'll get a crapton of ClassNotFoundExceptions when you try to start the plugin.

[granite owl]

can using pdc on a player cause the playerfile to get corrupted?

[ivory sleet]

it shouldn't

idk if its safe to use off the server thread

[granite owl]

i had the following: i stored an extra inventory in the player file using pdc

and then i killed myself to test it

went to title screen instead of respawn

and when i went back in

i was in an infinite loading terrain loop

when i deleted my playerfile i was able to login again

however since then i wasnt able to replicate the issue

public static void onPlayerJoin(main plugin, Player p)
    {
        File invDir = new File(Utils.getOwnDir + "inv");
        
        if (invDir.exists())
        {
            if (new File(invDir.getPath() + '/' + p.getUniqueId().toString() + ".bin").exists())
            {
                @SuppressWarnings("unchecked")
                HashMap<String, ItemStack[]> invs = (HashMap<String, ItemStack[]>) NonReflectables.deserializeBukkitObjectFromFile(invDir.getPath() + '/' + p.getUniqueId().toString() + ".bin");
                
                p.getInventory().setContents(invs.get("inv_main"));
                p.getEnderChest().setContents(invs.get("inv_chest"));
                if (invs.containsKey("inv_admin")) p.getPersistentDataContainer().set(new NamespacedKey(plugin, "inv_admin"), PersistentDataType.BYTE_ARRAY, NonReflectables.serializeBukkitObjectToByteArray(invs.get("inv_admin")));
            }
        }
    }
    
    public static void onPlayerQuit(main plugin, Player p)
    {
        File invDir = new File(Utils.getOwnDir + "inv");
        if (!invDir.exists()) invDir.mkdir();
        
        HashMap<String, ItemStack[]> invs = new HashMap<String, ItemStack[]>();
        invs.put("inv_main", p.getInventory().getContents());
        invs.put("inv_chest", p.getEnderChest().getContents());
        if (p.getPersistentDataContainer().has(new NamespacedKey(plugin, "inv_admin"), PersistentDataType.BYTE_ARRAY)) invs.put("inv_admin", (ItemStack[]) NonReflectables.deserializeBukkitObjectFromByteArray(p.getPersistentDataContainer().get(new NamespacedKey(plugin, "inv_admin"), PersistentDataType.BYTE_ARRAY)));
        
        NonReflectables.serializeBukkitObjectToFile(invs, invDir.getPath() + '/' + p.getUniqueId().toString() + ".bin");
    }

mhm

just some basic pdc

using byte arrays

to store the invs

everything works fine

is there a vanilla bug regarding dying/+going to title screen?

[gritty basin]

Is there any way to get structures to spawn in custom worlds?
we have a earth server and want it to have villages, ruined portals etc

[solid cargo]

i wanna recreate the buildmart plugin from mcc with my friend. idk what to start with tho. teams?

[sacred mountain]

What does the doesbounce do to a projectile

[eternal oxide]

it tells you in the javadoc

[steel swan]

guys i have a problem.
so i m using this :

public void playersList(String UUID){
        try {
             BufferedWriter writer = new BufferedWriter(new FileWriter("playerlist.txt"));
                
            writer.write("\n" + UUID);
            writer.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

to write in a file.
The problem is, if there is already smth in the file, it will delete it andjust write what i tell it to

i want it to add what i tell him to

[eternal oxide]

new FileWriter("playerlist.txt", true)

[steel swan]

BufferedWriter writer = new BufferedWriter(new FileWriter("playerlist.txt", true));

like this?

[tardy delta]

try with resources is a thing 😂

[scarlet sun]

Hello, I use intellij and i need a lil bit help. Is this the right place?

[noble lantern]

Whats up?

[scarlet sun]

Is it possible to do item event (compass), where you right click and it opens a gui, and it shows online people heads who have specific /team from minecraft, and when you select that player, the compass tracks the player? I already have an item made.

[vocal mirage]

Hello!
I use getProxy().getPlayer(UUID.fromString(s)) method to get a ProxiedPlayer from my UUID that I stored in a database.
The plugin throws me even though my server is in online mode & string S isn't null.

Can you help?

Thanks

[sage patio]

hologram is an Armorstand

but does not take affect

[lost matrix]

Is gravity disabled or is the ArmorStand a marker?

[sage patio]

marker yes

[lost matrix]

Show the exception or we cant help

[vocal mirage]

NullPointerException sorry

[sage patio]

so what should i do ?

[vocal mirage]

so object is null

[lost matrix]

Marker dont get ticked. Have a runnable that teleports armorstands.

[vocal mirage]

But I don't know why

[scarlet sun]

^^

[lost matrix]

Show the exception or we cant help

[scarlet sun]

Is it even possible?

[lost matrix]

Sure. Just open an Inventory, loop over all online players, filter out the ones with a specific team, listen to the InventoryClickEvent and set the compass target.

but i need to armor stand be non hitable ( sorry for my bad English )

[scarlet sun]

Okay, thank you so muchh

[lost matrix]

Have a runnable that teleports armorstands.

[lost matrix]

getsupportBungee is a very bad name for a class...
Anyways whats line 82?

[vocal mirage]

getProxy().getPlayer(UUID.fromString(s)).getDisplayName();
It's this method.

[vocal mirage]

it's main class, for bungee part of the plugin

[restive tangle]

Top tier naming

[lost matrix]

Ok then find out which object in there is null. Im suspecting that getPlayer(...) returns null.

[grave kite]

Hi, does someone know ServerTickStartEvent alternative for 1.12.2?

[lost matrix]

Btw if you use the latest java version then NPEs are way easier to debug.

[lost matrix]

Thats a paper event.

[lost matrix]

What do you need it for? You shouldnt run any logic in there.

[grave kite]

yeah, I'm looking for an alternative

[grave kite]

just to have an action before a tick happens

[vocal mirage]

yeah it's that

[lost matrix]

Which action and why does it have to happen when the tick starts?

[small lynx]

it is possible to save two different economies with vault? i want it to be able to save xp and coins for my KP-PVP plugin

[vocal mirage]

I'm using java 8, i'm coding in MC 1.12.
Upgrading to java 17/18 will fix the bug & will not impact my code?

[worldly ingot]

and why does it have to be an event when the scheduler exists?

Run a task that runs every tick

Not to mention, that's a Paper-exclusive event

[lost matrix]

Because the order of runnables are not determined. Ive used it to track the exact timestamp when a tick starts so that i know how many milliseconds my runnables are allowed to take.
For example if my runnable starts 32.5 ms after the tick started and they are only allowed to take 40 ms max then i know i can run them at least 2.5 more ms.

[small lynx]

it is possible to save two different economies with vault? i want it to be able to save xp and coins for my KP-PVP plugin

[grave kite]

to check player's positions, make timers, etc.

[lost matrix]

Then use a runnable

[worldly ingot]

Right, yeah, you don't need the start of a tick for that

That's more or less what I was getting at. The use-case for calculating the start of a tick are far and few between

Only reasonable one I can think of is Spark's profiler

[small lynx]

actually i use playerpoints for XP
and vault for coins
but i want to use only vault for both

[grave kite]

if I have a lot of listener classes with ServerTickStartEvent and ServerTickEndEvent, should I just make a runnable in the constructor? But I'm not quite sure how I distinguish tick start from tick end

[lost matrix]

Do you need offline data?

[grave kite]

Anti cheat for example

[small lynx]

i think that the XP will only be used for levelling up. so i dont think that i need offline data

[lost matrix]

Just run the cleanup of the previous tick on the start of the next one.

[small lynx]

and coins for purchase kits in shop

[vocal mirage]

pls help

[grave kite]

ok, thanks

[small lynx]

java 17 is only for 1.18 not for 1.12. use java 8

[vocal mirage]

but i think i could use java 11, as plugins need java 11 in 1.12

[glossy venture]

well yeah then use java 11

[small lynx]

java 8 works too

[vocal mirage]

yeah but java 11 is newer

[worldly ingot]

Certainly not required and few plugins did actually compile against 11 then

But if you can run 11, go for it

[small lynx]

someone can awnser me

[lost matrix]

Something like this:

public class SomeTaskRunnable implements Runnable {

  @Override
  public void run() {
    Collection<? extends Player> players = Bukkit.getOnlinePlayers();
    players.forEach(this::cleanUp);
    players.forEach(this::execute);
  }

  private void execute(Player player) {

  }

  private void cleanUp(Player player) {

  }

}

[grave kite]

it should look something like this, right?

Bukkit.getScheduler().sheduleSyncRepeatingTask(this, new Runnable() {
  public void run() {
    // code from ServerTickEndEvent
    // code from ServerTickStartEvent
  }
}, 1L);

[grave kite]

got it, thanks

[worldly ingot]

Last I recall, Vault only supported one currency.

[small lynx]

actually i use playerpoints for XP
and vault for coins
but i want to use only vault for both

[small lynx]

how i put a second

i use playerpoints. but i dont want to force people to install it

[sage patio]

i think in 1.12.2 a code a long time ago, was not like this, u can use marker true and give potions for flying ...

[rough drift]

Can you register a command on a specific server using BungeeCord?

or do I have to make a separate plugin

[scarlet sun]

import com.ignelis.tracker.items.ItemManager;
import org.bukkit.Bukkit;
import org.bukkit.Material;
import org.bukkit.entity.HumanEntity;
import org.bukkit.entity.Player;

import org.bukkit.inventory.ItemStack;

public class events implements Listener {

    @EventHandler
    public static void onRightClick(PlayerInteractEvent event) {
        if (event.getItem().getItemMeta().equals(ItemManager.kompasas.getItemMeta())) {
            Inventory inv = Bukkit.createInventory(null, 6 * 9);
            inv.addItem(new ItemStack(Material.APPLE, 64));
            HumanEntity player = event.getPlayer();
            player.openInventory(inv);

        }
    }
}

i think im doing something really wrong

[crisp steeple]

you could just check the server the command was used at, but if it’s only for one server i don’t see why you would use a bungee plugin

[scarlet sun]

I found a documentation from 2014

[small lynx]

where is the inv title?

[rough drift]

its enabled/disable for a specific server

[scarlet sun]

ah, i forgot

[rough drift]

the thing is I am already doing everything, is there a way to HIDE a command on serverA but not serverB

[small lynx]

put it then

[lost matrix]

Dont check custom items like this. Rather use the PDC of the ItemStack.

[crisp steeple]

like in the tab executor? you could just manually just make it say “unknown command type /help” if not

[rough drift]

yeah when you do / and it shows commands

[scarlet sun]

im only 1 week in plugin create, i don't understand ;-;

            Inventory inv = Bukkit.createInventory(null, 6 * 9, "GUI" );

is this good?

[lost matrix]

Sure this works.

[scarlet sun]

so when i right click compass, it should open?

[crisp steeple]

keep forgetting how useful pdc is

1.8 plugin making is pain

[rough drift]

TabCompleteResponseEvent is a thing, how can I check which command? (Bungeecord)

[scarlet sun]

it doesn't work

package com.ignelis.tracker.events;

import com.ignelis.tracker.items.ItemManager;
import org.bukkit.Bukkit;

            Inventory inv = Bukkit.createInventory(null, 6 * 9, "GUI" );
            inv.addItem(new ItemStack(Material.APPLE, 64));
            HumanEntity player = event.getPlayer();
            player.openInventory(inv);

        }
    }
}

[lost matrix]

public class CompassItem {

  private static final NamespacedKey COMPASS_KEY = NamespacedKey.fromString("someplugin:custom-compass");

  public static ItemStack create() {
    ItemStack compass = new ItemStack(Material.COMPASS);
    ItemMeta meta = compass.getItemMeta();
    PersistentDataContainer container = meta.getPersistentDataContainer();
    container.set(COMPASS_KEY, PersistentDataType.BYTE, (byte) 0);
    compass.setItemMeta(meta);
    return compass;
  }

  public static boolean is(ItemStack itemStack) {
    if (itemStack == null || itemStack.getType() != Material.COMPASS) {
      return false;
    }
    return itemStack.getItemMeta().getPersistentDataContainer().has(COMPASS_KEY, PersistentDataType.BYTE);
  }

}

public class CompassEvents implements Listener {

  @EventHandler
  public void onClick(PlayerInteractEvent event) {
    if (CompassItem.is(event.getItem())) {
      openCompassInventory(event.getPlayer());
    }
  }

  private void openCompassInventory(Player player) {

  }

}

And giving a player the compass item is as easy as:

    player.getInventory().addItem(CompassItem.create());

🥄

You should take a look at this:

?pdc

[undone axle]

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

[lost matrix]

There are several ways. One would be to listen for the packet that tells the player the list of commands when he joins.

TabCompleteResponseEvent might also work

[rough drift]

I only need it to not show when you type / yk

That's really it

[crisp steeple]

just wondering, how does the pdc on itemstacks work? if i had 1 item without a container and another one with it then i stacked them together, do they both get the container?

[rough drift]

I don't believe you can stack two items that have value in their containers

[lost matrix]

They dont stack. The NBT data differs. You cant stack them like you couldnt stack items with lore or different names.

[crisp steeple]

ah i see

so it does come down to nbt in the end

just simpler

neat

[hexed hatch]

If the value they hold is the same, they can stack, right?

[lost matrix]

Yes

Its also one way to make an ItemStack unstackable: Just give them a PDC entry with a random UUID as value.

[small lynx]

how i put a second
i use playerpoints. but i dont want to force people to install it

[lost matrix]

If you want a quick approach: Use the PDC of the Player to store their XP

[small lynx]

what is PDC

[lost matrix]

?pdc

[undone axle]

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

[small lynx]

it only works for 1.14?

[lost matrix]

Yes. 1.14+ But everything else is ancient anyways.

[rough drift]

1.16.5 is ancient

older than my grandma

[lost matrix]

I mean 1.16.5 community is still decently big. Bigger than 1.8 and 1.12

[rough drift]

ofc

but like

still ancient

[jagged thicket]

not bigger than 1.8

[lost matrix]

lol yes

[jagged thicket]

u mean 1.18??

still no

[lost matrix]

1.12 1.16 1.17 1.18 are (on their own) all bigger than 1.8

[jagged thicket]

Howw

the pvp cliker bois

they are too big

[lost matrix]

Because 1.8 is a bubble where everybody thinks they are the biggest community while in fact they are vanishingly small.

[rough drift]

fair but like, they are only alive because of hyp

[hexed hatch]

I don’t even know if Hypixel can be considered 1.8

[rough drift]

eh

it is

[hexed hatch]

They’ve probably built their own server from the ground up

[small lynx]

what is the best? Vault or https://www.spigotmc.org/resources/treasury.99531/

[quaint mantle]

1.8 is increasingly getting smaller, only amplified from pvp montage and strictly hypixel YouTubers

[small lynx]

to plugin developement

[rough drift]

nah

probs use some spigot fork

[lost matrix]

doubt that it will be a replacement for vault. Vault (this old garbage) is just too sticky.

[rough drift]

One of the hyp admins was coding on a stream and it looked like spigot

[small lynx]

do you recommend switching to Treasury?

[jagged thicket]

is there a way to see vanish insta msgs on pc

[rough drift]

Treasury seems neat

[small lynx]

Treasury is compatible with vault plugins? Like EssentialsX

[dusty sphinx]

how does Container#getContents work? Does it return empty item stacks for empty slots

[quaint mantle]

Never heard of Treasury before, it actually looks really cool

[lost matrix]

It returns an ItemStack[] with null values on empty slots.

[dusty sphinx]

Ok. Will changes to the array be reflected or do I need to setContents

[dull whale]

how can I paste a schematic?

[hexed hatch]

It’s definitely built on bukkit/spigot, but I believe the base game has been altered a ton

[lost matrix]

Programmatically?

[dull whale]

of course

[dusty sphinx]

?

[lost matrix]

https://enginehub.org/documentation/

[dull whale]

I've been looking for the best way but web's full of deprecate methods n stuff I wanna know the current best method

[lost matrix]

What are you trying to do? You can do an index iteration and Inventory implements Iterable<ItemStack>.
You can do a lot without the getContents() overhead.

[lost matrix]

https://worldedit.enginehub.org/en/latest/api/examples/clipboard/#schematic-examples

[dusty sphinx]

I'm trying to filter out items with illegal enchantments, so I think I will just turn the result of getContents into a stream and then flatten it back down to an array and put it back into the container with setContents

Are ItemStacks mutable?

[lost matrix]

This is a lot faster than doing any stream fuckery:

  public void removeAll(Inventory inventory, Predicate<ItemStack> filter) {
    for (int index = 0; index < inventory.getSize(); index++) {
      if (filter.test(inventory.getItem(index))) {
        inventory.setItem(index, null);
      }
    }
  }

[dusty sphinx]

Are ItemStreams mutable?

*ItemStacks

[ivory sleet]

yep

[lost matrix]

Yes. The underlying truth is a bit more complicated but they are mutable.

[scarlet sun]

import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.inventory.Inventory;

public class komanda implements CommandExecutor{
    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        if (sender instanceof Player){
            Player player = (Player) sender;

            Inventory gui = Bukkit.createInventory(player, 9, ChatColor.RED + "Žmogžudžių gaudytojas");
            player.openInventory(gui);
        }

        return true;

    }
}

I made this as a command, how can I make it as a right click event?

[rough drift]

wait, so I could've just done itemStack.setAmount(itemStack.getAmount() - 1); and it would update in the inv?!

[ivory sleet]

not always

thats the "complication"

[lost matrix]

[ivory sleet]

because most of the times, the implementation copies your ItemStack instance to an identical CraftItemStack instance

[rough drift]

why can't it just be consistant.... le sad

[scarlet sun]

It opens inventory, how can i make inventory open when i right click a compass

[lost matrix]

Listen for the PlayerInteractEvent and open the inventory if the conditions are met

[dusty sphinx]

is the map returned by item.getEnchantments mutable

[severe oracle]

hi, for some reason when i try to add a component to JFrame outside the main function, it doesent get added.

[rough drift]

show your code

because otherwise, I ain't a fuckin magician

[lost matrix]

The javadocs are not conclusive on this one. I would just use a combination of
containsEnchantment(Enchantment ench) and removeEnchantment(Enchantment ench)

[dusty sphinx]

I want to modify enchantments. Not remove them

[lost matrix]

In which way? Reduce their level?

[dusty sphinx]

yes

[severe oracle]

it seems like i cant attach a file to this channel: https://www.mediafire.com/file/0cwgcq47841jtfz/code.txt/file

[dusty sphinx]

After I modify the ItemStack do I need to set it back into the Inventory or does it just update automatically

[rough drift]

or

you can

otherwise

code

[lost matrix]

getEnchantmentLevel(Enchantment ench) (returns 0 if not present)
addEnchantment(Enchantment ench, int level) <- replaces the level

But you can also try using the map. Tell me if it worked in that case.

[ivory sleet]

well you get an immutable copy

[rough drift]

addUnsafeEnchantment

ftw

[dusty sphinx]

so the map is immutable?

[ivory sleet]

nah

[rough drift]

n o

[ivory sleet]

but getEnchantments and ItemMeta::getEnchants will return immutable copies

[rough drift]

oh yeah

forgot maps can be imumtable

[dusty sphinx]

can you answer this

[ivory sleet]

you need to set it back

[dusty sphinx]

ok

[rough drift]

sometimes

[ivory sleet]

pretty much always

i wanna remake the buildmart minigame from mcc with my friend. what should i start with? I have already imported WG and WE api

[scarlet sun]

    @EventHandler
    public static void onRightClick(PlayerInteractEvent event) {
        if (event.getItem().getItemMeta().equals(ItemManager.kompasas.getItemMeta())) {
            Player player = event.getPlayer();
            Inventory gui = Bukkit.createInventory(player, 9, ChatColor.RED + "Žmogžudžių gaudytojas");
            player.openInventory(gui);

        }
    }
}

Should this work? Sorry for being dumb, as i said im only a week into a programming

[short raptor]

How can I set an item's durability? The whole damageable interface thing is very confusing to me and I can't find any examples online

[ivory sleet]

mind elaborating how that mingame of yours works

[ivory sleet]

?tas :3

[undone axle]

https://tryitands.ee

[ivory sleet]

well

get the itemmeta

[solid cargo]

so, you have a schematic that server tells you to remake, once it remade, you get points :)

[short raptor]

Yeah I've got that

[ivory sleet]

and check if it instanceof Damageable

if so, cast it to Damageable and set the durability

[steel swan]

so i have this code : ```java
public boolean containsPlayer(String name){
try {
BufferedReader reader = new BufferedReader(new FileReader("playerlist.txt"));
String line;
List<String> listToWrite = Collections.emptyList();
while((line = reader.readLine()) != null) {
listToWrite.add(line);
}
reader.close();
if (listToWrite.contains(name)){
return true;
}else{
return false;
}

    } catch (IOException e) {
        e.printStackTrace();
        return false;
    }
}

and
```java
@EventHandler
    public void onPlayerJoin(PlayerJoinEvent event){
        Player player = event.getPlayer();
        System.out.printf("0");

        if (!containsPlayer(player.getDisplayName())){
            playersList(player.getDisplayName());
            playersData(player.getDisplayName(), "CITOYEN", 0);
            setjobs(player, Job.CITOYEN);
            setmoneyInt(player, 0);
        }
}
``` but when i run it, i get an error : 
```[14:44:59] [Server thread/ERROR]: Could not pass event PlayerJoinEvent to LunaRpDev v1.0-SNAPSHOT
org.bukkit.event.EventException: null```
https://paste.md-5.net/lenoqusiqu.bash

[solid cargo]

@scarlet sun are you lithuanian?

[scarlet sun]

yea, why

    @EventHandler
    public static void onRightClick(PlayerInteractEvent event) {
        if (event.getItem().getItemMeta().equals(ItemManager.kompasas.getItemMeta())) {
            Player player = event.getPlayer();
            Inventory gui = Bukkit.createInventory(player, 9, ChatColor.RED + "Žmogžudžių gaudytojas");
            player.openInventory(gui);

        }
    }
}

Anyways, this is not working

What am I doing wrong

[short raptor]

Don't I need to save this back to the item meta?

[ivory sleet]

yes you do

set the item meta back after the setDamage call

[steel swan]

?paste

[undone axle]

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

[short raptor]

I don't think I am doing the right

[ivory sleet]

nope

definitely not

[solid cargo]

@ivory sleet so you gotta remake the schematic given on the left square on the square to the right

and so plugin checks if ur done it, if yes, give points, else, do nothing and wait

[ivory sleet]

var stack = ...;
if (stack.getItemMeta() instanceof Damageable damageable) {
damageable.setDamage(4);
stack.setItemMeta((ItemMeta)damageable);
}
or sth

[short raptor]

whaaaaaaaaaaaaaaaaaa

Okay I will try that ig

[lavish hemlock]

Only works on newer versions of Java :)

[lost matrix]

With a couple thousand unique players this will single-handedly lag out your server.

[steel swan]

the server isnt big

[short raptor]

How new? What's oldest version it works on

[lost matrix]

Even with a few hundred if people log in a bit more often.

[solid cargo]

sure it isnt. what if it explodes in popularity during the night?

[lavish hemlock]

Smthn like Java 16

[short raptor]

Ok thx

[lavish hemlock]

Besides, you should really only code in either Java 8 or Java 16 since those are the two versions Minecraft uses :p

[steel swan]

its a PRIVATE server

so anyone knows about the error?

[lost matrix]

Then dont write/read to/from a file that often. When the server starts -> Load every entry in a Set<UUID>
and only use this Set during runtime. Then when the server stops you simply write the whole Set to a File again.

[solid cargo]

https://tenor.com/view/ice-eating-ok-and-gif-19666657

[steel swan]

ik but thats just a test for smth else, but do you pls know the error?

[solid cargo]

still looking for where to start btw

reminder i have we and wg api already installed

[lost matrix]

Yes. Collections.emptyList() returns an immutable collection (like stated in the javadocs and the error)
Use new ArrayList<>() instead

[vocal mirage]

can someone help?

[steel swan]

oh yeah

[lost matrix]

Im suspecting that the UUID is simply not connected on the proxy.

[knotty gale]

how would I make a message send every time someone shoots a bow using EntityShootBowEvent

[lost matrix]

Use the EntityShootBowEvent and send a message... lol

[knotty gale]

but like how would I get the players name my b

[vocal mirage]

ah yeah.

[maiden thicket]

Entity by EntityShootBowEvent#getEntity

Name by Entity#getName

[vocal mirage]

So how can I store a "player identity" in a DB?

[lost matrix]

^ Like this. You can check if the shooter is a Player by using instanceof

[vocal mirage]

it's fetching data that was saved when the server closed

[lost matrix]

Use their UUID as primary key

[steel swan]

there si still an error
https://paste.md-5.net/wicodekozi.bash
the 2 lines are the same
the code changed a bit :

public boolean containsPlayer(String name){
        try {
            BufferedReader reader = new BufferedReader(new FileReader("playerlist.txt"));
            String line;
            String[] listArray = {};
            List<String> listToGet = Arrays.asList(listArray);
            while((line = reader.readLine()) != null) {
                listToGet.add(line);
            }
            reader.close();
            if (listToGet.contains(name)){

        } catch (IOException e) {
            e.printStackTrace();
            return false;
        }
    }

[vocal mirage]

it's what I do. But when the servers restarts, it "rebuilds" the data that was saved when it stopped. And I need to get the ProxiedPlayer object, so what can I do? And the player isn't online when it does that

[lost matrix]

Arrays.asList(listArray); returns an immutable List. As stated by the javadocs and the exception.

[steel swan]

and so what should i do?

[lost matrix]

Please. Just create a new instance of an ArrayList like its taught in java 101

[lost matrix]

The ProxiedPlayer is session scoped. It only exists if a user is connected to the proxy.

[steel swan]

like that
ArrayList<String> listToGet = new ArrayList<String>(Arrays.asList());

[lavish hemlock]

Wouldn't it be super fucking slow to re-read the player list per method call...?

[lavish hemlock]

Okay I feel like

You're just trolling

[steel swan]

no bro

i m just making what he told me to

[lavish hemlock]

He did not tell you to use the copy constructor of the list

[vocal mirage]

ah ok

[lavish hemlock]

He told you to make a new list

Learn how the fuck to make a list because it's one of the most common things in Java

[steel swan]

bro like why do you want me to create an other list one is created with that no?

[lavish hemlock]

Nah okay you're trolling

[steel swan]

BRO

if i m doing smth wrong just explain to me

i dont quite get what you want me to do

[lost matrix]

Im also getting troll vibes to be honest. The list is completely useless to begin with.

[lavish hemlock]

This is like legitimately the worst code you could write

[steel swan]

oh nvm i think i get it

[knotty gale]

wait why is there a hashtag?

[lavish hemlock]

Violates LSP, explicit righthand type parameter, empty Arrays.asList as the parameter of a collection's copy constructor.

[severe oracle]

hi, for some reason when i try to add components to a JFrame outside the main method it wont be added to the frame.

[maiden thicket]

it just means that getEntity is a member of EntityShootBowEvent

[steel swan]

i m stupid

i get it

so sry

[knotty gale]

so I would do

        Entity Shooter = EntityShootBowEvent#getEntity;

[steel swan]

i created an array but not a list

[lavish hemlock]

Okay listen lemme point the shit out for you

[steel swan]

calm down bro i created a list and it worked

[lavish hemlock]

1. You should declare your variable as List<String> listToGet instead of ArrayList<String> listToGet because of conventions that are semi-complicated to explain.
2. You do not need to declare the String in new ArrayList<String> because of the "diamond operator," you can refactor this to just new ArrayList<>.
3. It is pointless to create an empty Arrays.asList within the "copy constructor" of an ArrayList, the copy constructor copies the contents of another list into the list you're creating. You should remove this parameter to create a new empty ArrayList.

So

In other words

[short raptor]

Now this is setting the item durability to 0 🤔

[lavish hemlock]

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

That's all you need to do.

Uhh

Well the style comes from javadocs

Javadoc conventions state that you should declare parentheses if it is actually important

e.g. if you're differentiating between two overloads

[warm saddle]

how would i get the itemstack that is in a specific slot in an inventory from an inventoryclickevent?

[gritty basin]

What are some cool money making plugins?

[knotty gale]

essentialsX

what is a way to make a Listener that listens for if a bow was shot

[lost matrix]

listen to the EntityShootBowEvent

[knotty gale]

yeah but it wont work

[lost matrix]

Yes it will

[knotty gale]

public class ArrowShot implements Listener{
    @EventHandler
    public void EntityShootBowEvent(org.bukkit.event.entity.EntityShootBowEvent event2) {
        if(event2.getEntity() instanceof Player) {
            Bukkit.broadcastMessage(event2.getEntity().getName() + " threw the ball");
        }
    }
}

this wont work for some reason

[lost matrix]

Did you register the listener? Also import your packages instead of using them like this.

[knotty gale]

lemme check if i did it right though

ok how do I register a listener that is not the Main class?

because I do not need @Override right?

[tardy delta]

is Collections.emptyList() mutable? 👉👈

[gritty basin]

thats essentials, not a money making plugin like guishop

[lost matrix]

No

[knotty gale]

i beleive Essentials comes with a money thing

[tardy delta]

methods shouldnt start with a uppercase letter

[gritty basin]

They do but it suks, everyone uses vault

and thats just a currency holding thing

[lost matrix]

Write your own plugin then

[gritty basin]

Im not a femboy coder

[lost matrix]

Then move to #help-server

[knotty gale]

how do I register a listener that is not the main class?

[ivory sleet]

How does this at all relate to being a femboy?

[tardy delta]

Bukkit.getPluginManager().registerEvents(new ListenerClass(), plugin)

or plugin, listener idk

[warm saddle]

how would i set the time for a ban using target.getServer().getBanList(BanList.Type.NAME).addBan method, i know you need to do target.getServer().getBanList(BanList.Type.NAME).addBan(player, banReason, <time>, mod) how would i make the time 14 days, would i just put 14d otrrr

[lost matrix]

Create an instance of it and call PluginManager#registerEvents(...) with it

[tardy delta]

it requires a Data object or smth

so look at the methods in that class

[scarlet sun]

how can i filter out the ones with a specific team online players?

[craggy cosmos]

:dynoError: The AFK module is disabled in this server.

[sterile token]

Scoreboard team?

[scarlet sun]

no, like /team

[echo basalt]

Just use epoch seconds for that

[warm saddle]

it has to be a Date object

[sterile token]

ms can be directed converted into date object?

So then its posible to get the hours, seconds, etc from the date?

[warm saddle]

would this be an issue because this is 14 days in milliseconds: 1.21e+9

yeah it wants it to be a Long not a Date

yep that works, thank you :)

[flat olive]

he means he’s a femboy but not a femboy coder😉

[ivory sleet]

So? why would you say that? It's just so out of context

[sacred mountain]

lmao what

[flat olive]

[steel swan]

hey , i have this code to check if smth from a file is smth
:

if(containsPlayer(player.getDisplayName())){
            int index  = getIndexOfPlayer(player.getDisplayName());
            String text = readerFile("file.txt", index + 1);
            System.out.println(text);
            if (text == "CITOYEN"){
                System.out.printf("is");
                setjobs(player , Job.CITOYEN);
            }
            if (text == "STAFF"){
                System.out.printf("is");
                setjobs(player , Job.STAFF);
            }
            if (text == "VISITEUR"){
                System.out.printf("is");
                setjobs(player , Job.VISITEUR);
            }
            setmoneyInt(player , 0);
        }

The output in the console is CITOYEN, but the condition if (text == "CITOYEN"){ doesnt work

anyone knows why?

the output :

[flat olive]

yes

[ebon arrow]

How do you like that browser?

[flat olive]

use text.equals()

use equals() method

[steel swan]

the output : [16:26:32] [Server thread/INFO]: CITOYEN

[tardy delta]

i used opera gx a while ago 😳

its just slow

[steel swan]

yeah but i like the look of it

[kind hatch]

String comparisons should be done with .equals() not ==.

[lost matrix]

Dont compare Strings with ==
It checks for identity not equality.

[lost matrix]

Btw this is a very, very bad approach to whatever you are doing. And its also way more complicated than it needs to be.
Constantly reading and writing from/to files on the main thread is just super bad.

[lost matrix]

Same. Def not gonna shove more data down googles throat than i already do.

[sterile token]

I dont understand the shity schedules, because the methods args are named bad. So its said: runTaskLater(plugin, runnable, l, l1);

So i dont know what shity means l and l1

yes indeed it takes so much space up

now time to code again

[lost matrix]

Download sources and documentations in your maven project.

[sterile token]

sources?

[tardy delta]

<type>javadoc<type> is it that?

ah

[sterile token]

Isnt suppoused to be done once you run the build tools?

🤔

[kind hatch]

The first one is the delay, second one is the interval in which it will repeat.
Also, I thought that #runTaskLater() only had one parameter which was the delay. Are you sure you didn't mean #runTaskTimer()?

[tardy delta]

wondering the same thing

[sterile token]

Yes lmao im stressed to be using apis that doesnt contain good methods, arguments

[tardy delta]

so you there is your explaination :)

[sterile token]

Oh yeah, sorry my mistake. I mean runTaskTimer()

Oh nice getting an NPE when comparing item displayname with config displayname. Amazing hahahaa

😂

[kind hatch]

No worries. You just have to remember that both the delay and the interval period for the bukkit scheduler are in ticks instead of milliseconds. So 20 ticks is 1 second.

[sterile token]

Oh so they are in ms, ticks?

Because long can be anything hour, seconds, etc

[kind hatch]

No, they are just ticks. You would have to do the math if you wanted it to be something like seconds or minutes.

[sterile token]

That what i hate from the apis that are not good coumented

[kind hatch]

Yes, it takes a long as the parameter, but it's interpreted as game ticks.

[sterile token]

But its okay its not a paid api

If im paying for the api of course i will argue

But thanks Shadow and sorry for fucking you

[steel swan]

whats the other approach

[scarlet sun]

I can't find any of the working docs where how i should get all online players and add their skulls to gui

is there a way to do it?

[lost matrix]

Using classes and collections on runtime and only reading/writing data when the server starts/stops.

[sterile token]

You should catch the file data on memory and then yes do what ever

[tardy delta]

the item probably doesnt have a displayname so getDIsplayeName is returnin null? or it is annotated notnull?

[kind hatch]

That's one of the things that annoys me about item comparisons.
The method #hasDisplayName() can thrown an NPE instead of just returning false.

[lost matrix]

Split up the task into smaller sub-tasks. First problem you need to solve: How to create a Skull ItemStack from a Player.
Implement the following method:

public ItemStack createPlayerHeadItem(Player player)

[sterile token]

I have done a debug when player interact and the displays its there. So maybe my fault its when catching the data

[kind hatch]

If it's on the player interact event, then the item could be null in certain cases. Or the wrong one.

[lost matrix]

Thats because there is a single type of material that doesnt have an ItemMeta: air

[sterile token]

Allr i dint know that

[scarlet sun]

in eventhandler?

[sterile token]

I dont have another way to compare my items

[scarlet sun]

sorry for ping btw

[sterile token]

Or atleast i dont kno

[void shale]

@EventHandler
public void onBlockExplode(final BlockExplodeEvent event) {
    event.blockList().forEach(x -> {
        ...
    }
}

Would this be a good way to deal with blocks that are being destroyed by tnt or creeper?
I tried it but i think it did not fire up :/

[sterile token]

Do you decompile the method?

[kind hatch]

The PlayerInteractEvent is fine for comparisons, you just need a few more null checks in place to prevent errors from being thrown.

[void shale]

I just wrote it for my plugin, I need to do some special actions when blocks are exploded

[lost matrix]

No the class this method is in doesnt matter. You should decouple your concerns. Your first is: "How to convert a Player to a Skull ItemStack"
and this method tries to solve this task.

[flat olive]

does anyone know how to get all of the permissions of what a user has in a string format

String playerPermissions = Bukkit.getServer().getPluginManager().getPermissions();

getEffectivePermissions() only returned it in an object and someone told me to loop with getPermissions, however, I have no clue how to start

[kind hatch]

Did you register the listener?

[scarlet sun]

Ah, okay, i did it, what now? I should just add the item to gui?

[lost matrix]

First show your implementation

[sterile token]

Allr thanks, could you check this? Im not so good with sections maybe there its the issue:

ConfigurationSection section = getPlugin().getConfig().getConfigurationSection("Items");
section.getKeys(false).forEach(name -> {
  getPlugin().getLogger().info("Item " + name + " (Display: " + section.getString("Display") + ")" + " loaded");
});

[void shale]

I added @EventHandler anotation I think thats all I did for other events

I can share screen if that would help to show

[tardy delta]

take a look at https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/permissions/Permissible.html#getEffectivePermissions()

[sterile token]

You must use the @EventHandler annotation when listening to events

[flat olive]

I did that however, the output is always ```java
[org.bukkit.permissions.PermissionAttachmentInfo@333d287f, org.bukkit.permissions.PermissionAttachmentInfo@3c8e3f0d,

and its never in string format

[kind hatch]

That's not enough for the events to be registered. You need to register them with PluginManager#registerEvents().
You can get an instance of PluginManager in your main class through #getServer()#getPluginManager().

[void shale]

oh I have this on my main class:
this.getServer().getPluginManager().registerEvents(new Events(),this);

[lost matrix]

PermissionAttachmentInfo has a method called getPermission() which returns the String representation.

[scarlet sun]

should i just copy what you wrote?

public ItemStack createPlayerHeadItem(Player player)

[flat olive]

bruh thanks

[void shale]

wait would it print to console if i use regular System.out.println?

[tardy delta]

did you call getPermission on it?

[kind hatch]

Then put some output in the event to see if it's being fired. If it is, then it's a problem with the code for the event. Otherwise, it's not registering properly.

[lost matrix]

Sure. But that is only a method stub. You need to properly implement it. Thats your first task.

[sterile token]

The value should be true (if active) and false (f not active) right?

[kind hatch]

If you are looping though a configuration section, you need to make sure that you pay attention to the paths.

[lost matrix]

Nope. This is already solved.

[flat olive]

nope I was just using .toString()or wrapping it with String.ValueOf() or parsing it to json, or gson, etc. I tried for like 5 hours not knowing there was a method

[scarlet sun]

public class .... implements ....

something like this?
@lost matrix

[sterile token]

Oh i have this path:

# Custom items configuration
Items:
  test:
    Display: "&6Test"
    Material: Compass
    Lore:
      - "&7This is a test item."
      - "&7It has a lore line."
      - "&7It has another lore line."
    Slot: 1
    Command: ""

The last one is the only official one, however some of those concepts assume that you already know a bit about programming.

[sterile token]

Agree

[kind hatch]

Will there be more than one item that you can loop through?

[sterile token]

yes

Because im looping over each item and creating a memory object for each item

[kind hatch]

Ok, so you need to pay close attention to how you format your string.

You will want to loop through the config section Items using #getConfigurationSection("Items").getKeys(false) It will return the names of every sub item in the list. So in your case it would just return test.

If you had more, it would be part of the list.

You can use that to then build your string.

If you wanted to get the display name: "Items." + sectionName + ".Display"
If you wanted to get the slot: "Items." + sectionName + ".Slot"

[scarlet sun]

Im sorry if it will look funny, but should i just import import org.bukkit.inventory.ItemStack? I don't really understand..

oh nvm

nvm

sorry

[sterile token]

Ohh ok

[lost matrix]

Ive sent you a method stub. Meaning a method with a specific purpose but no implementation.
Your task is to write code that makes the method do what its supposed to do.

  getPlugin().getLogger().info("Item " + name + " (Display: " + section.getString("Display") + ")" + " loaded");
  Item item = new Item(name, getPlugin().getConfig().getString("Items." + name + ".Display"));
  item.setSlot(getPlugin().getConfig().getInt("Items." + name + ".Slot"));
  item.setCommand(getPlugin().getConfig().getString("Items." + name + ".Command"));
  ItemBuilder material = new ItemBuilder().of(Material.valueOf(getPlugin().getConfig().getString("Items." + name + ".Material")));
  material.name(getPlugin().getConfig().getString("Items." + name + ".Display"));
  material.lore(getPlugin().getConfig().getStringList("Items." + name + ".Lore"));
  item.setItem(material.build());
});

[kind hatch]

Your items would be created properly, but your console output wouldn't be what you expect.

[lost matrix]

This naming looks scuffed

[tardy delta]

my eyes

[tardy delta]

look at the docs

[void shale]

I am confused even if do this and exploded tnt nothing is being send to players:

@EventHandler
public void onBlockExplode(final BlockExplodeEvent event) {
        App.plugin.getServer().getOnlinePlayers().forEach(y -> y.sendMessage("Lasagna!"));
}

[lost matrix]

Did you register the Listener class?

[kind hatch]

Then it seems that your listener isn't properly registered.

What class is that method in?

[tardy delta]

main class 😟

[void shale]

In my Events class which implements Listener and on main class I have:

public void onEnable() {
        App.plugin = this;
        App.config = App.plugin.getConfig();
        this.getServer().getPluginManager().registerEvents(new Events(),this);
    }

[lost matrix]

I sure hope App.plugin and App.config are not, [public static non-final] variables...

[kind hatch]

Well, that looks right to me. How are you trying to trigger the event? TNT, Creeper?

[void shale]

TNT

[tardy delta]

why having a config field

[lost matrix]

Oh yeah. btw: BlockExplodeEvent only triggers when a Bed explodes

[void shale]

whole main class:

package lt.lucy.lucyutils;

import org.bukkit.block.Block;
import org.bukkit.configuration.file.FileConfiguration;
import org.bukkit.plugin.java.JavaPlugin;

public final class App extends JavaPlugin {
    public static FileConfiguration config;
    public static App plugin;

    public void onEnable() {
        App.plugin = this;
        App.config = App.plugin.getConfig();
        this.getServer().getPluginManager().registerEvents(new Events(),this);
    }

    public void onDisable() {}
}

[tardy delta]

do a sysout before the player looping

[void shale]

🥲

[lost matrix]

You need the EntityExplodeEvent for TNT and Creepers

@tardy delta
https://gyazo.com/94e2a240f616351d31a905c1fde02237
That is the output after using getPermission

[kind hatch]

Wouldn't the BlockExplodeEvent also apply to Respawn Anchors if it goes by that logic?

[lost matrix]

*For the respawn anchor it also fires now i suppose

[flat olive]

oh and permissions is a string field not a array

[lost matrix]

MongoDB. What do you use for serialization? Because this looks scuffed.

[kind hatch]

An individual permission node sure, but players will have more than one. So it will likely be that they have an array of permissions.

Hello guys, do you guys have any idea of how i could, possibly modify a line of a file?
Here is an exemple.
For instance, guys, if i have a file where the first line is x and the second one is y.
i want it so that, i can modify the second line by saying that it is the second line that i want to modify and , for instance , replace the y with a z

yes there is https://gyazo.com/94e2a240f616351d31a905c1fde02237

it only outputs my permissions as if it were an object surrounded with a string 🤣

[tardy delta]

depends on the signature of the asFuture method

This wont work. it would only save the last permission.

Have you tried outputting it to console? Just to see if it returns what you are looking for?

[tardy delta]

well could you show the asFuture method?

Because you clicked on an empty slot. What else do you expect to be in there?

else return isnt really a good practice writin that

[warm saddle]

i didn't i am clicking a book not an empty slot

so it shouldn't be null

just make a check for null and return

bruh

it doesnt really matter what it should be if it isnt that

just add a null check, it can be null and you dont want exceptions

you aren't clicking anywhere else on the screen? not even to make the mc window your active window?

thats one thing I'm not getting rid of 😛 doesn't hurt to leave out the brackets for easily readable statements and stuff

Honestly this looks a bit like bad API design because you can enforce type safety for stuff like that by keeping the casts internal.

i only leave my brackets out for returns

is 32kb for a database good enough to hold 10,000+ players in it?

player data related

uuid, name, permissions

[tardy delta]

no

[flat olive]

how much space would I need then

[tardy delta]

lol what question is that

[flat olive]

im dead serious I mean you need a big database to hold player data

gotta be prepared

[crimson terrace]

see it like this, if you wanted to have 10000 players in a 32kb database you would have 3.2 bytes for each player. I dont think thats enough

[kind hatch]

Potentially Infinite? It all depends on how the data is stored.

How it's converted and accessed via memory.

[eternal oxide]

I'm going to guess your NPE happens when you go to drop an item in to a slot

[flat olive]

Hm I guess so

[kind hatch]

A uuid might be stored as a string, or a binary blob, or maybe it could be encoded. Resulting in different sizes of data.

[flat olive]

yeah

[kind hatch]

Names will likely be strings, so they will be relatively large.

Same with permission nodes.

You'd probably want at minimum 10GB of storage for a large database.

[flat olive]

https://gyazo.com/8697805907b22d2063007e286c4c464b

Yeah I wonder how much those cores cost

im gonna check

[kind hatch]

I mean, I did the math a while ago for YAML storage and holy shit can it grow to absurd numbers quickly.

I'm talking about Gigabyte range in storage and ram usage.

[flat olive]

Yeah I think its best to have some code to delete some rows of users who haven't played in months, unless they donated or have special perms

[kind hatch]

Databases will obviously be smaller in size, but you could be working with a gigabyte of data if the database is large enough.

[crimson terrace]

how many lines?

[flat olive]

https://gyazo.com/badf92d645437074412f708ce7cbfd03 not bad tbh

[kind hatch]

Lines didn't matter that much. The file sizes were about 1-5KB so assuming the worst at 5KB per player, it gets large quickly.

But, that's really due to how YAML stores its data.

It's all one big string.

[crimson terrace]

5kb for one player is a lot damn

one byte per char, was it?

[flat olive]

dude what the heck

mongdb pays by the hour

[kind hatch]

Yea, the base player file is ~1KB and I wanted to keep track of unique stats. So I needed to log several interactions with the player. Resulting in an ever growing file.

[flat olive]

jesus

[crimson terrace]

god I'm glad for my plugins I dont have to save player data

[mortal hare]

5MB for 1000 player data

its nothing in today's world

[kind hatch]

Maybe so, but that shouldn't be an excuse to ignore the benefits of smaller file sizes.

[crimson terrace]

5MB is 5MB and could be used in other places if youre able to make the files smaller

[kind hatch]

It's a real challenge to make small programs. Just take a look at the really old school programs/games that had to be made with less than 5KB of storage.

[crimson terrace]

this is the error

cant cast the getOnlinePlayers to an ArrayList I believe

instead you should make a new ArrayList<>(p.getServer().getOnlinePlayers())

[kind hatch]

That's because #getOnlinePlayers() returns a Collection.

You need to make a new arraylist instead of casting.

[tardy delta]

which is immutable

[sick ermine]

In minigame addons such as bedwars, skywars, can a map be in only one game?

Probably. They likely use copies of a map and remove them once the game is over.

If you only had one map, then you could only have one game running at a time.

Got a bit of a design question. As of right now I have an interface called PlayerDataManager. It's currently responsible for handling everything related to the player. Data, preferences, etc.

My question is should I split the interface up into multiple different interfaces? Something like, PlayerDataManager, PlayerPreferencesManager, etc.
As of right now, it's a bit annoying having to update implementations with the new methods even though they don't really apply to them. However, it's real simple to work with as everything is consistent in the one class.

[supple elk]

How can I check this cast?

What's the theme?

You could use unsafe casts and keep them internal.

[supple elk]

I could yeah, though I'd prefer to make it safe if possible

can I not do a try catch?

It really depends on how you structure your data. For player related data i have a single class: PlayerData that has a ton of sub-data fields like LevelData etc.

[lost matrix]

Nope

wow I don't have to pay for mongodb storage if im only keeping track of this data because this data is just a few bytes and I have about 282 bytes on free cluster

[flat olive]

(500 megabytes) / (300 bytes) =1,666,666 users/w/userdata

Its safe if you strongly encapsulate the casts.

[eager knoll]

ItemBuilder b = new ItemBuilder(item).setName(name).setLore(description + ChatColor.GOLD + "\nCost: " + ChatColor.GRAY + "$" + price);
The "setLore" class only gets the first element of what I gave it (description) to output, any way I can fix this?

if the max stack size allows it

[ornate mantle]

what

[quaint mantle]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/inventory/Inventory.html#setMaxStackSize(int)

idk how this works

[ornate mantle]

alr lets say the max stack size is default

[quaint mantle]

but it exists 🤷🏿‍♂️

[ornate mantle]

and i set an item amount to 65 and give it to a player

will the player get a stack and one item

[quaint mantle]

no

probably just throws an exception

[ornate mantle]

well that sucks

[kind hatch]

No. I think the method has a safeguard that puts it to the max size. Either that or it throws an exception.

[ornate mantle]

the docs dont mention an exception

[quaint mantle]

weird

?stash

[undone axle]

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

[ornate mantle]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/inventory/ItemStack.html#setAmount(int)

oh

"in this stack"

probably throws an error

[quaint mantle]

no

it doesnt on stash

try it and see

maybe an internal error instead

[ornate mantle]

wjat

what am i meant to do with the stash

[quaint mantle]

i was looking at the code

    /**
     * Sets the amount of items in this stack
     *
     * @param amount New amount of items in this stack
     */
    public void setAmount(int amount) {
        this.amount = amount;
    }

try it

[ornate mantle]

imma just make a loop and fill all the required spaces

[quaint mantle]

its probably an internal error

[ornate mantle]

If you pass in ItemStacks which exceed the maximum stack size for the Material, first they will be added to partial stacks where Material.getMaxStackSize() is not exceeded, up to Material.getMaxStackSize(). When there are no partial stacks left stacks will be split on Inventory.getMaxStackSize() allowing you to exceed the maximum stack size for that material.

alright

Example for a registry using the class as key for internal type safety.
First some product class:

  public abstract class Game {

  }

Then a factory class for this product:

  public abstract class GameFactory<T extends Game> {
    public abstract Class<T> getGameClass();
    public abstract Game createGame();
  }

Now we want to have a registry for centralised access to those factories:

public class GameRegistry {

  private static final Map<Class<? extends Game>, GameFactory<? extends Game>> gameFactoryMap = new HashMap<>();

  @SuppressWarnings("unchecked")
  public static <T extends Game> GameFactory<T> getFactoryForGame(Class<T> gameClass) {
    return (GameFactory<T>) gameFactoryMap.get(gameClass);
  }

  public static <T extends Game> void registerGameFactory(GameFactory<T> gameFactory) {
    gameFactoryMap.put(gameFactory.getGameClass(), gameFactory);
  }

}

You can see here that i suppressed the warnings for unchecked casts because the only way to add elements to the internal
map is my calling the registerGameFactory method which assures type safety. This is called strong encapsulation. All the casts happen internally
and you assure type safety by that.
Example for registering factories:

  public static void registerGames() {
    GameRegistry.registerGameFactory(new SkyWarsFactory());
    GameRegistry.registerGameFactory(new OneBlockFactory());
  }

And here you can see the type safe usage with everyone outside this class not having to do any unsafe casts:

  public static void createSomeGames() {
    SkyWars skyWars = GameRegistry.getFactoryForGame(SkyWars.class).createGame();
    OneBlock oneBlock = GameRegistry.getFactoryForGame(OneBlock.class).createGame();
  }

[supple elk]

aaah

kk

so I'd done all that expect I was using an id as the key not the class

so there could theoretically be duplicates

or they pass in a string which isn't registered

but yeah by using the class itself there will never be an error

[lost matrix]

The problem with your approach is that the String doesnt provide any type context...

[spring current]

I tried to make it so that blocking your sword Will make you take 0 damage instead of 0.5 but it didnt work. Can someone help me?

[lost matrix]

Im guessing you are using a spigot version that is half a decade old?

[supple elk]

yeah

[spring current]

No its just i'm not good at coding

[supple elk]

well, it would to the user

[lost matrix]

What spigot version are you using?

[supple elk]

cause if I had a game called skywars the id would be "skywars" or similar

[spring current]

1.8.8

[supple elk]

but that's a very different thing

[lost matrix]

Well... this is half a decade old. Anyways: Listen to the EntityDamageEvent and check if the defender is of type Player, then cast, then check if the player is blocking.
If so -> set the damage to 0.

[kind hatch]

7smile7: Are you using 1.8?
Fawwazpow3145: No
7smile7: Then what are you using?
Fawwazpow3145: 1.8

lmao

[spring current]

He said what version i'm using

[supple elk]

he was referring to 1.8 here

[spring current]

Oh

Yea i'm just really stupid

[supple elk]

lol dw

[lost matrix]

Should be something in the lines of

  @EventHandler
  public void onDamage(EntityDamageEvent event) {
    if (event.getEntity() instanceof Player player && player.isBlocking()) {
      event.setDamage(0);
    }
  }

[spring current]

THANKS

[feral socket]

java 16 in 1.8, yeah right

[lost matrix]

Just with old java and the isBlocking() might not exists

[spring current]

I just learn coding 2 days ago lol

[spring current]

Yea i tried that before

[feral socket]

what exactly did you try?

[spring current]

Who, me?

[feral socket]

no, not you

[supple elk]

also had you seen what I was doing earlier?

cause this is eerily similar lol

which is probably a good sign

[knotty gale]

I am rying to detect if a arrow hits a block

and I am wondering how to check if it hits a certain block

[supple elk]

also @lost matrix can I register with the GameFactory class instead?

[feral socket]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/entity/ProjectileHitEvent.html#getHitBlock()

[supple elk]

though I'm guessing not considering this..?

[knotty gale]

I already checked here it does not answer the question

[lost matrix]

This looks weird. Why is GameType not an enum? Does it need to be dynamic?

[supple elk]

GameType is equivalent to GameFactory

[feral socket]

what do you mean? seems to me like it's perfectly apt to check the block that's been hit?

[lost matrix]

gameType.getClass() is not what you want here.

  public static abstract class GameFactory<T extends Game> {
    public abstract Class<T> getGameClass(); // <- This is the extra method that returns the Class<T>
    public abstract Game createGame();
  }

[supple elk]

why not?

[knotty gale]

it checks if a block that has been hit not if a certain block has been hit

like how do I check WHICH block is hit
