Ok thanks!

[quaint mantle]

You may need to create all combinations and register the recipe

[modest garnet]

Hey all,

this is probably a message you will skim over.
However me and my mate have an amazing idea for a project
however we are in need of a developer.

if this is something you are interested in then the idea can be
further explained in DM

there is a slight catch. me and this mate are both students.
money is not the easiest to come by. however we are devoted to this server
and would love to have someone join the team. and once the server has launched etc
money that we receive we will aim to provide you with money worth your time (dependent on server growth)

any questions or possible discuses the offer please DM me

im working on a crafting engine where you can configure it to work with any skull, but its sort of broken rn

[upper tendon]

There a reason my server would use 50% of my CPU just having a player run around?

[humble tulip]

Check timings

ope ya

[dark harness]

Where is the problem with my recipe?
I added 5 items with count 1 and the plugin disables with the message i cannot have more then 9 ingredients
https://paste.labymod.net/epibegejor.cs

[elfin tusk]

So I'm currently trying to get an advancement using this Bukkit.getAdvancement(NamespacedKey.fromString("advancement here")) and it only works with default minecraft advancements, not custom ones. Does anyone know a way to be able to make it work with custom ones as well?

[modest garnet]

your code is setting all the ingredients to be placed in slot 1 of the crafting table
you need to actually make the recipe

1, 2, 3
4, 5, 6
7, 8, 9

[dark harness]

So the first parameter is the slot?

[snow sluice]

How do you set durability of players item?

                    ItemStack item = player.getInventory().getItemInMainHand();
                    Damageable meta = (Damageable) item.getItemMeta();
                    meta.setDamage(500);```

doesnt work

[modest garnet]

i believe so i could be wrong just going of memory

[dark harness]

no, that's wrong too D:

[crisp steeple]

pass your plugin instance as the second paramater in NamespacedKey.fromString

[elfin tusk]

Would that make it work with both custom and default advancements, though?

[modest garnet]

show me line 89 of survival.jaca

java

[crisp steeple]

if you want to get a default advancement then you could use NamspacedKey.minecraft("advancement")

[elfin tusk]

okay

is there a way to make it work with both or no

[dark harness]

one of these two
`ShapelessRecipe recipe = new ShapelessRecipe(new NamespacedKey(this, "Chunkloader"), ChunkLoader);

recipe.addIngredient('1', Material.CREEPER_HEAD);`

[crisp steeple]

not really since thats the whole point of namespaced keys, you can just check both though

[brave sparrow]

The first parameter is an integer

It’s the “amount” of the item you need

So 1 creeper head

Since that’s a shapeless recipe there is no “slot”

Not ‘1’, 1

RankManager: https://paste.md-5.net/newujodoto.cs
RankEnum: https://paste.md-5.net/onasawuhac.java

Problem: I dont understnad why I cant do player.setDisplayName(Rank.prefix.get(rank) + player.getName());

[brave sparrow]

Because that’s not a method you made?

?learnjava

[undone axle]

Here are some links to get you started on learning Java:

• https://www.codecademy.com/learn/learn-java
• https://www.sololearn.com/learning/1068
• https://www.learnjavaonline.org/
• https://programmingbydoing.com/
• https://docs.oracle.com/javase/tutorial/java/index.html

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

[tardy delta]

Rank.prefix.get(rank) + player.getName() 😵

[ocean lion]

I did make it

[brave sparrow]

Rank.prefix isn’t a static variable it’s a local one

Lol

[brave sparrow]

No you didn’t

You need to learn Java before attempting this

[ocean lion]

Someones angry

[tardy delta]

lul

[brave sparrow]

I’m not angry 😂

[modest garnet]

Rank.getPrefix() not rank.prefix.get

[tardy delta]

calm down (╯°□°）╯︵ ┻━┻

[brave sparrow]

I’m just letting you know that you lack the required knowledge to make a plugin

And where to obtain said knowledge

[tardy delta]

running into a very weird compilation error "cannot find symbol" however at the line described there are no problems whatsoever

any1 any idea what could be causing this?

[brave sparrow]

Show us the line

[elfin tusk]

got it to work, thanks for the help, though :)

[lost matrix]

invalidate caches and restart

[tall dragon]

tried it. did not work

[lost matrix]

Wrong path or dependency is missing

[tall dragon]

shoulnt it say "does not exist" then?

[chrome beacon]

Did you import a dependency from the jar directly with your IDE and then try to build with maven

[lost matrix]

Make sure you have your jdk set up so "import" is recognised.

[tall dragon]

its a module

[kind hatch]

Did you install the module?

[tall dragon]

well it gets auto installed

[eternal oxide]

is it configured in your pom as a module. Does it correctly have its own pom?

[tall dragon]

as my other module needs it

[tall dragon]

it is

[cunning shard]

Hey for some reason when i added a cooldown thing to my taser plugin the cooldown doesn't work and the console goes nuts

[tardy delta]

show the code

and what does the console say?

[cunning shard]

import org.bukkit.entity.Player;

import java.util.HashMap;
import java.util.UUID;

public class Cooldown {

    public static HashMap<UUID, Double> cooldowns;

    public static void setCooldowns() {
        cooldowns = new HashMap<>();

    }

    //setCooldown
    public static void setCooldown(Player p, int seconds){
        double delay = System.currentTimeMillis() + (seconds*1000);
        cooldowns.put(p.getUniqueId(), delay);
    }
    //getCooldown
    public static int getCooldown(Player p){
        return Math.toIntExact(Math.round((cooldowns.get(p.getUniqueId()) - System.currentTimeMillis())/1000));
    }

    //checkCooldown
    public static boolean checkCooldown(Player p){
        if(!cooldowns.containsKey(p.getUniqueId()) || cooldowns.get(p.getUniqueId()) <= System.currentTimeMillis()){
            return true;
        }
        return false;
    }


}```

[lost matrix]

Only rule that matters for cooldowns:
Dont use runnables for decrementation. Always use timestamps.

[tardy delta]

uhh looks like making it more difficult with static

[cunning shard]

huh

[slim kernel]

what is the best way to store a date in json?

[tardy delta]

https://github.com/FourteenBrush/MagmaBuildNetworkReloaded/blob/ca3e3a118ba9089a50d569457a5d7a25709cb9eb/src/main/java/me/fourteendoggo/MagmaBuildNetworkReloaded/user/Cooldown.java
how i did my cooldowns

and then i stored them in the player data

[lost matrix]

1. Make the map private. You should never make any data structure (like maps, sets and lists) public and you should never have any getter or setter for them.
2. Combine setCooldowns and your field initialisation.
3. Use Longs for timestamps

private static final Map<UUID, Long> cooldowns = new HashMap<>();

[lost matrix]

There is no "best" way. If it doesnt need to be readable then you can just use a unix timestamp.

[tender shard]

Cooldowns are a thing you can write once and then reuse it everytime. https://github.com/JEFF-Media-GbR/JeffLib/blob/master/core/src/main/java/de/jeff_media/jefflib/cooldown/Cooldown.java

[slim kernel]

and how do I convert it into a readable date then?

[cunning shard]

I am so confused

so it has to be private?

[tender shard]

For example with a DateTimeFormatter

[cunning shard]

everything else is fine?

[tender shard]

it doesnt have to be but it doesnt make sense to not make it private

[cunning shard]

sounds about right

[lost matrix]

new Date(Long);

[cunning shard]

fuck how do i send images

[tender shard]

get verified

!verify

[undone axle]

Usage: !verify <forums username>

[cunning shard]

i literally dont have an account

[tender shard]

then create one

[cunning shard]

fair enough

[tender shard]

😄

[cunning shard]

ight now i can send the error

[tender shard]

your "cooldowns" object is null

[cunning shard]

y tho?

[tender shard]

probably you never assigned any object to that field

idk, send your code

[cunning shard]

im so stoopid tf

[dark harness]

How can i check if a recipe is already added?

[tardy delta]

https://tenor.com/view/javascript-hadouken-code-programming-gif-16271428

[lost matrix]

Iterate through all recipes and see if the NamespacedKey exists already

[covert karma]

dont make a setCooldowns method just initialize it right at the top

[cunning shard]

oh like before anything else?

in the interact thingy?

[eternal oxide]

or https://hub.spigotmc.org/javadocs/spigot/org/bukkit/Bukkit.html#getRecipe(org.bukkit.NamespacedKey) and check if its null

[glossy venture]

yay generics

god damn

[lost matrix]

This is one way to do it when you want to use a higher level approach than raw millis.

public class Cooldown {

  private static final Instant ZERO = Instant.ofEpochMilli(0);
  private static final Map<UUID, Map<Object, Instant>> CD_MAP = new HashMap<>();

  public static <T> void setCooldown(Player player, T key, Duration duration) {
    CD_MAP.computeIfAbsent(player.getUniqueId(), k -> new HashMap<>()).put(key, Instant.now().plus(duration));
  }

  public static <T> boolean isCooldownDone(Player player, T key) {
    return Instant.now().isAfter(CD_MAP.computeIfAbsent(player.getUniqueId(), k -> new HashMap<>()).getOrDefault(key, ZERO));
  }

  public static <T> Duration getCooldownLeft(Player player, T key) {
    return Duration.between(CD_MAP.computeIfAbsent(player.getUniqueId(), k -> new HashMap<>()).getOrDefault(key, ZERO), Instant.now());
  }

}

[cunning shard]

to be fair i dont wanna make it too intricate or complicated

[lost matrix]

Nested collections -> Create new classes

[tardy delta]

my EyEs kekw

[glossy venture]

oh thats a pretty good idea

im not very excited to implement all the methods tho

so i think ima leave it like this

[cunning shard]

is that code bad or good im so confused

[lost matrix]

Do it. Makes your code more robust and readable.

[tardy delta]

i should be working with durations too instead of separate timeunits and longs

[waxen plinth]

Who doesn't love a Map<List<String>, Function<Set<Predicate<Integer>>, IntUnaryOperator>>?

[glossy venture]

ah yes

classic

[lost matrix]

Yeah. Throw some Pairs and Tuples in there too...

[cunning shard]

i feel like an idiot for not understanding anything

[lost matrix]

But who in their right mind would use a List<String> as a primary key

[waxen plinth]

We all start somewhere

[waxen plinth]

I have done that before lol

[covert karma]

no just in the same line

[waxen plinth]

Well, it was String[] but still

[covert karma]

Map<UUID, Double> cooldowns = new Hashmap<>();

[lost matrix]

Dont. Thats like one of the later steps you take when learning oop. First you need to get amazed by inheritance. Later
you throw it out the window because you discover composition.

[tardy delta]

primitive generics 🥺 🙏

[cunning shard]

for line 10?

[tall dragon]

turned out it was not compiling because i had <finalName> in my pom with a space in it

no idea what that had to do with line 7

[covert karma]

ye

[tall dragon]

mystery to me

[cunning shard]

it creates errors i dont understand

[true perch]

Having an issue deleting a file using the java.io.File delete method. I'm able to read the contents of the File object, but when it comes to actually deleting that same object it does not work.

[tardy delta]

?notworking

[undone axle]

"Does not working" is a useless statement. Please describe what exactly is not working, what you expect it to do, and what actually happens. If you get any console errors, also ?paste the entire stacktrace.

[true perch]

The file does not get deleted and I'm not sure why.

[glossy venture]

lmao

need to cast it to the raw type

[lost matrix]

Use NIO instead.

     Path filePath = Paths.get("path/to/your/file.yml");
     try {
         Files.delete(filePath);
     } catch (IOException ioException) {
         ioException.printStackTrace();
     }

[true perch]

Thank you, will do

[glossy venture]

i always use Path.of(...) does that matter

[lost matrix]

I think it does the same

[glossy venture]

oh yeah lol

[tardy delta]

ye lol

[ornate patio]

https://hub.spigotmc.org/javadocs/spigot/org/spigotmc/event/entity/EntityDismountEvent.html is getDismounted() the entity that was being ridden, or the entity that is moving off the vehicle?

[humble tulip]

Javadocs don't say

I'd assume that get Dismounted would return the horse

[tardy delta]

im confused too

[humble tulip]

And getEntity returns player

[covert karma]

yea

wth are these names

[humble tulip]

For player and horse that is

[covert karma]

Entity what

[humble tulip]

There are other stuff

[ornate patio]

yeah lmao its confusing

thanks

[humble tulip]

They could've called it rider or something

[covert karma]

yeah like getVehicle and getRider

[humble tulip]

Or passenger

[covert karma]

ye

[humble tulip]

Since that's what it's called in spigot

event.getWhat

[humble tulip]

Thank god its getEntity and not this

[glossy venture]

bruh how th do i get rid of these 0% classes ...

[humble tulip]

Wdym?

[covert karma]

what editor is that

[glossy venture]

intellij

[west scarab]

[covert karma]

intellij theme?

[glossy venture]

like the stats on the right of each item

[humble tulip]

Did u register it?

[glossy venture]

i think material

idk

[west scarab]

how do i register a cmd?

[glossy venture]

with a background image

[tardy delta]

google it

[glossy venture]

with i believe either material or atom icons

[covert karma]

https://www.spigotmc.org/wiki/plugin-yml/

[west scarab]

i have that in the on enable but idk if that registers cmds

[glossy venture]

no

you need to define the command in the plugin.yml

[humble tulip]

in ur onEnable
this.getCommand("cmdhere").set Executor(command class instance here)

[tardy delta]

getCommand(name).setExecutor(new ClassThatExtendsCommandExecutor())

[golden turret]

Help

[glossy venture]

and then set the code to run with plugin.getCommand(name).setExecutor(commandExecutor);

[tardy delta]

smh

[glossy venture]

where plugin is this in your main class

[covert karma]

you can also just use the onCommand method but make sure that you command is specified in your plugin.yml

[tardy delta]

¯_(ツ)_/¯

[ornate patio]

its the other way around rip

[humble tulip]

Oh god

[ornate patio]

or wait

nvm its not

[humble tulip]

That's stupid

Oh great

[west scarab]

still not working

[covert karma]

i guess its "what entity have you just dismounted" or something idk

[tardy delta]

console errors?

[covert karma]

oh

[west scarab]

none

waitt i fixed

[limpid bronze]

Hey, how I can calculate the number of times a Shapeless recipe can be crafted in my custom crafting gui?

[cunning shard]

i still get the same Caused by: java.lang.NullPointerException: Cannot invoke "java.util.HashMap.containsKey(Object)" because "me.saeko.taser_plugin.Cooldown.cooldowns" is null error for my cooldown thing

[noble forge]

I am getting this error when I run my maven build

error: invalid target release: 17.0.2

Module HAES SDK 17 is not compatible with the source version 17.

Upgrade Module SDK in project settings to 17 or higher. Open project settings.

Does anyone know what it could be?

[covert karma]

why do you want to know this

[limpid bronze]

Because i want to implement shift click and i will do a loop for every time the craft is possible

[covert karma]

wdym

[tardy delta]

dont initialize your map in a static method, do a direct initialisation

[cunning shard]

I literally have no idea what that means im sorry

[covert karma]

i already sent the answer above

just do that

[covert karma]

here

[cunning shard]

literally what i did

[tardy delta]

instead of static void initMap() { map = new HashMap }
just do Map<bla, bla> map = new Hahsmap() directly

[glossy venture]

what in the world

[cunning shard]

i think i messed up

[limpid bronze]

Like if you can craft 5 netherite ingot with scrap and gold, when you shift click it give you all the 5 netherite ingot instead of clicking one by one

[covert karma]

thats just default behaviour

[covert karma]

why do you have two maps now

[limpid bronze]

it's a custom crafting gui

[cunning shard]

I have no idea

[covert karma]

remove the Cooldown map and instead initialize the cooldowns map

[tardy delta]

cuz you made them ¯_(ツ)_/¯

[covert karma]

i guess iterate over the items and count how many materials there are?

[glossy venture]

yeah and then take the minimum from that

[cunning shard]

sorry for being annoying but i gotta remove private static HashMap<UUID, Double> cooldowns;
?

[limpid bronze]

okay and?

[covert karma]

no lol

[cunning shard]

my fucking brain is on airplane mode

[covert karma]

private static Map<UUID, Double> cooldowns = new HashMap<>();

[tardy delta]

yes

and in my opinion you should make it a long, as youre using system.currentimemillis

[glossy venture]

then take amount items from every ingredient and set the result to the desired item with amount itemsPerCraft * amount

[limpid bronze]

okay thanks very much

[glossy venture]

np

[cunning shard]

holy shit that worked thank you and im sorry for being stupid

[glossy venture]

ah shit

worth a shot

[thick scarab]

Did u run buildtools?

Also do u use mojang mappings?

i don't get why im getting the error..?

[humble tulip]

World name is null

[west scarab]

this is my config

spawn:
    - player: # where /pve will take the player
        - x: 100
        - y: 100
        - z: 100
        - world: "world"```

[humble tulip]

That cuz that's a list

Not a valid config path

Remove the -

Also the spacing on that looks weird

[humble tulip]

https://www.spigotmc.org/wiki/config-files/

[west scarab]

this better?

spawn:

        x: 100
        y: 100
        z: 100

ok, worked

Are you sure that it is not fired for armorstands? Sysout the type to validate pls.

Im suspecting that the metadata packet afterwards just respawns the armorstand for the player.

[golden turret]

I will try that

[golden turret]

Yes I am. Even if I add a sysout, it will never be fired

[golden turret]

It did not work

[lost matrix]

And did you add a sysout for the other spawn packet?

[golden turret]

Yes, I tried for both PacketPlayOutSpawnEntityLiving and PacketPlayOutSpawnEntity but the PacketPlayOutSpawnEntityLiving is only fired for a creeper I have, the other is not even fired

Hey all,

this is probably a message you will skim over.
However me and my mate have an amazing idea for a project
however we are in need of a developer.

if this is something you are interested in then the idea can be
further explained in DM

there is a slight catch. me and this mate are both students.
money is not the easiest to come by. however we are devoted to this server
and would love to have someone join the team. and once the server has launched etc
money that we receive we will aim to provide you with money worth your time (dependent on server growth)

any questions or possible discuses the offer please DM me

[lost matrix]

Then you need to find out which packet is sent to tell the player that an armorstand was spawned.

Hello guru Spigot tell me how can I disable logging of some commands?

[humble tulip]

Playercommandpreprocessevent

Cancel it

Get the command from the commandmap

And pass the args to the execute method woth the sender as the player

You basically have to handle command execution yourself

Maybe there's a better way to do it but that's how i would

If it's your own command, you can use playercommandpreprocessevent as your command executor basically

what are you using it for actually?

https://www.spigotmc.org/wiki/connecting-to-databases-mysql/

[bold copper]

Thanks. I need to cancel the command and manually call the code that is being executed, right?

[tardy delta]

if you learn some basic sql it wont

[humble tulip]

Yep

[humble tulip]

Field commandMapField = Bukkit.getServer().getClass().getDeclaredField("commandMap"); commandMapField.setAccessible(true); commandMap = (CommandMap) commandMapField.get(Bukkit.getServer());

If it's for another plugin, u can get the commandmap and knowncommands with reflection to call the method manually

[echo basalt]

^ modifying the command map only works during onEnable for some reason

[humble tulip]

He doesn't need to modify it

[humble tulip]

That also makes sense since plugins are initialized very early on

Maybe even before bukkit does its commad stuff

[waxen plinth]

you sure?

because it's worked fine for me

[echo basalt]

I attempted to register a command after the first tick, and it simply didn't work

[waxen plinth]

how did you do that

because I have a plugin manager

it can load plugins at any time, and their commands register just fine

[echo basalt]

by accessing the commandmap and registering stuff after connecting to Db

[waxen plinth]

and they use my command framework which registers them through the command map

[echo basalt]

getCommand works, but messing with the commandmap is kinda icky

[waxen plinth]

the commands that will be sent as tab completions don't get updated automatically

you have to call something else, I forget what it is

but to my knowledge you can still register commands just fine after the first tick

[echo basalt]

Odd

[waxen plinth]

https://github.com/Redempt/PlugWoman/blob/master/src/redempt/plugwoman/PlugWoman.java#L236

[echo basalt]

it would just not do anything in my case

[waxen plinth]

It's a private method syncCommands in CraftServer

[echo basalt]

Could be that

[bold copper]

Maybe someone knows what the team's color change is related to? No matter how much I searched, I couldn't find it

[worldly ingot]

It's public

[bold copper]

For example, when there is an error in the vanilla command, it turns red

[humble tulip]

U have to call that to refresh tab completions?

[waxen plinth]

Yes

[humble tulip]

I was having a problem with tab completions being oresent after removing and unregistering commands

I assume this fixes it?

[waxen plinth]

In 1.13+ it should

ConfigurationSection#getKeys(false)

Or change it to true if you want the entire config tree

Excluding map lists sadly

Curse you map lists, you make writing config libraries so difficult 😩

https://github.com/Redempt/RedLib/blob/master/src/redempt/redlib/config/data/DataHolder.java

Look at the shit I had to do to get map lists working with my serialization lib

I had to make a wrapper that can wrap either a map, list, or config section to be able to read from and write to it from config

It's not like it was crazy difficult it's just that this shouldn't have been needed

All that's necessary is to make it possible to index lists with numbers

So:

thing:
- hi
- hello
- hey```

thing.0 = hi

thing.2 = hey

like it just makes sense

😢

Can you not just do getKeys(false) on the root?

YamlConfiguration is a ConfigurationSection

The hell

It 100% works

👍

[minor otter]

do persistent leaves still call any log check events?

[waxen plinth]

pretty sure

since a leaf that is player-placed and has a log placed or destroyed next to it will update observers

which is pretty funny lol

it's a form of instant redstone

a very powerful one actually

because it doesn't interact with any other redstone components except at the input and output

[dark harness]

Is the ´e.getChunk().setForceLoaded(true);´ function persistent after reload/restarts?

[waxen plinth]

reloads yes

restarts no

[minor otter]

so do you think I could use LeavesDecayEvent for persistent leaves?

[waxen plinth]

and it is instant, long range, and can go in any direction easily

[waxen plinth]

no

because player-placed leaves do not decay

[lost matrix]

I would only do this for the very first time and if you detect it once then you change the BlockData

*If you want to make generated leaves non-decayable

[minor otter]

that's not what i'm trying to do but thanks for the tip

[minor otter]

alright

[sage patio]

Hi, I've a custom sign shop works with Interact and SignChange event
When i made a shop with a sign like this
First line: [Buy]
My plugins gives that line a color
and when i'm cheking for that in InteractEvent is a switch case for sign's 1th line, does not work! (needs the chat color too for the check)
Buy, sell and many other type of shops have different colors, what should i do?

[eternal oxide]

use stripColor in teh switch statement

[lost matrix]

Sign is a PersistentDataHolder. Identify the customs signs not by their text but by their PDC

mca are nbt files
https://minecraft.fandom.com/wiki/NBT_format
You can take a look at apps like "NBT Explorer" and see how they read the files.

[sage patio]

so what should i do?

[sage patio]

how 😁

[lost matrix]

Identify the customs signs not by their text but by their PDC

[eternal oxide]

So as 7smile78 said. tag each sign with a flag in its PDC.

but if you can't/don't want to do that you switch (ChatColor.stripColor(signtext))

[sage patio]

thanks

[echo basalt]

sql

[eternal oxide]

If just on the local server sqlite

depends on the amount of data

[lost matrix]

Save it to a File or into a Database.

Its persisted independent from the host. Meaning multiple server instances/applications can access it.

[waxen plinth]

it can be indexed much more easily without loading it all into ram

[lost matrix]

Its easier to migrate your data. Queries are also a benefit. But all of that really only matters if you
expect thousands of players or several server instances.

[eternal oxide]

It all comes down to what data you want to store

[woeful crescent]

when my data plugin is disabled, it dumps records for all players.

when a player quits, their record is dumped.

many times when i stop the server, i get a concurrentmodificationexception.

any reason why?

[lost matrix]

because you concurrently modify a collection...

[woeful crescent]

?

[lost matrix]

Probably something like

for(Element element : elements) {
  elements.remove(element);
}

But we need more context.

[eternal oxide]

sqlite, just initialize teh driver

sql server, an installation

[tardy delta]

sqlite vs h2?

[lost matrix]

You mean programmatically interact with the DB or how to install a DB on your host.

[woeful crescent]

shooooot

*imagine a really hard facepalm, so earthshattering that the ground probably just shook in your country*

[lost matrix]

1. A running Database
2. The Driver for that DB

Just read through this:

[tardy delta]

Hey guys, could we somehow use the StructureType in order to remove something ? I'd like to make an event that moves the stronghold to another location 🤔

You can place a Structure, removing is unlikely

[shy shadow]

Do you have a tip on how to place it ? Can't seem to have a methode to create it ? 🤔
To remove it I could just look for certain blocs and remove them i guess

[eternal oxide]

Read teh Javadoc it tells you how to get the Manager and use structures https://hub.spigotmc.org/javadocs/spigot/org/bukkit/structure/Structure.html

what version of Spigot is your server running?

[formal bear]

api 1.18

[eternal oxide]

update it

PlayerProfile was added in 1.18.2 I think

[formal bear]

hm i want to use it on 1.18+ so, do i need to use deprecated setOwner or?

[eternal oxide]

You just need to have your server running a new enough jar

[formal bear]

i want to run this on 1.18.1 jar

[eternal oxide]

then You can;t use PlayerProfile

[humble tulip]

Gotta use reflection and gameprofile

[golden turret]

How can I make the spectator's name not have a low opacity and italic style?

Cuz a req has to be sent to mojangs servers to get the texturees

can i change api without any errors then? xDD

[humble tulip]

Wdym?

to 1.18.2 from 1.18.1 to get PlayerProfile

U can't

It depends on the server version

U can use this tho

To set the skull

It's version independent

Oroblem is it doesn't work with names

So u gotta get the texture code urself

[formal bear]

hm okay

tysm

[humble tulip]

That's pretty easy to do tbh just google it

Get texture async and set it sync

[dark harness]

How can i get mobs to spawn in a forceloaded chunk without a player?

[formal bear]

whole skin texture or only head?

wdym texture ;D

like this

[ornate patio]

bump 🪂

also quick java question

public class StatsMenu extends SubMenu {

    private ArrayList<Pane> panes = new ArrayList<Pane>();

If i do this will the panes array be the same for every object from this class or no

[eternal oxide]

only if you make it static

[ornate patio]

is it evaluated at run-time or every time when an object is created

[desert loom]

no it will be different for every instance of StatsMenu

[ornate patio]

ok good

because is python it does the opposite

[humble tulip]

maybe do getNavigation.moveTo(Path, double)

i think the double is the speed

[ornate patio]

ive tried that

[humble tulip]

what happens?

[ornate patio]

literally nothing

horse is still innocent

[uneven fiber]

anyone know how to get the top half slab of a oak block?

or just top half slab in general

[ornate patio]

my bad, it works now

there was something wrong with maven

thanks

[eternal oxide]

getBlockData cast to Slab

[ornate patio]

is it possible to check if the horse can make it to the target position? For example I've set this horse to walk 10 blocks in the positive x direction and it ends up walking around the wall and then gives up half way through

i wanna be able to check if it wont "give up"

also sometimes the horse will find a new target halfway through

how do i prevent that

[minor otter]

what event is called when leaves change their distance value?

i've tried blockphysicsevent but it didnt work

[ivory sleet]

@ornate patio you need to make sure no goal is overriding with the navigation, also check if its stuck, then you might wanna try to re-invoke move to or sth

[ornate patio]

how do i do all that

idk much about nms

[ivory sleet]

Explore it a little bit then? Read how mojang wrote their navigators, as well as goals

Smile gave you the hint, but in case you didn’t get it, ServerListPingEvent

[humble tulip]

Look thru the methods u can invoke when u getNavigation

[ivory sleet]

And look through the goals of said entity, there is a high plausibility they interfere with the navigation during normal occasions

Too bad

[ornate patio]

alright

thanks

[uneven fiber]

appreciate it

[minor otter]

bump

[ashen quest]

print the string and check if it is over 30

[eternal oxide]

Color codes take 2 each

do a .getBytes() on the string and see how long that is

[uneven fiber]

Is it possible to cast itemstack to Slab?

If so how does one do this

[ivory sleet]

Nope it’s not possible

[uneven fiber]

What about a material

[ivory sleet]

No

[uneven fiber]

damn

so only block?

[ivory sleet]

No

[uneven fiber]

..

[ivory sleet]

get the block data of a block

And cast that to Slab

[uneven fiber]

got it

[alpine coral]

Is there a way to automatically update the server? As I'm going to be using the new paper 1.19 release I'd like to have future fixes be added on their own

or would I need to make a script running alongside the server to do that for me

and restart the server periodically

[ivory sleet]

You would have to… yes

[alpine coral]

ic

[ivory sleet]

Myeah I mean that’s the safest way to do it Ig

And then, ofc create some back ups every once in a while

[waxen plinth]

you really should not have that sort of thing done automatically

there could always be zero day exploits or breaking changes

and you would blindly update (if you'd consider something like this, no doubt you'd forego proper logging) and potentially break things and not really be able to know why

[uneven fiber]

Im getting an error when I cast it,

Any ideas why?

[eternal oxide]

The block you are getting doesn;t seem to be a Slab

Perhaps is a sign?

[uneven fiber]

Hmm let me try something

Is there anyway to spawn/do the warden's attack

[ornate patio]

how do i get the goals of an entity

[ornate patio]

also how can i get the nms source code to use as a guide

[drowsy helm]

decompile server jar

[ornate patio]

how do i do that

[drowsy helm]

use something like jd gui

[desert loom]

IntelliJ/Eclipse have plugins (I think IntelliJ might have it built in?) to decompile code

I've used that in the past to look at nms and it worked pretty well

[ornate patio]

uh

i'm using vscode tho

[desert loom]

there's probably an extension for vscode as well somewhere

try searching in the extensions tab

[drowsy helm]

just use jd gui

its easy

[desert loom]

or that yeah

[ornate patio]

isnt that an eclipse plugin

[drowsy helm]

no

its just a standalone jar

run it, drop the server jar in

[ornate patio]

alright

um

this is all thats in it

[earnest forum]

yeah because the jar doesnt contain the classes for development anymore

?bootstrap

[undone axle]

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

[ornate patio]

where do i download this

[earnest forum]

build tools

[ornate patio]

i mean

I'm talking about original server jar

[earnest forum]

wait

you want nms classes?

[ornate patio]

yes

im trying to see the source code of nms

[earnest forum]

in the buildtools dir

there should be a jar that is generated which has nms and spigot api

it'll be under like spigot-server

[ornate patio]

oh wait

i figured it out

thanks

[sterile token]

Good nigh, im havin some troubles on my command api because on my custom Command class i need an instance of my plugin

But i cannot figure which is the best way to pass the instance

I need to pass an instance from a message api

[uneven fiber]

is there a way to get the relative face of the realtive face

^this is about blocks

[river oracle]

yea you can get the block connected to the face

[uneven fiber]

oh snap

how do you do this?

[sterile token]

Why the heck when im doing class#getMethodName() it showing the super class when the @Getter is set to some fields

Really weird

[uneven fiber]

hmmm i think im going insane

[humble tulip]

what do u mean?

the relative face of the relative face?

[uneven fiber]

actually i figured it out just now 💪

stupid mistake

[minor otter]

how could I stop leaves from changing distance blockstate

Does anyone know about registering and unregistering commands via the commandmap?
I'm having a problem where if i unregister a command from the commandmap that had overwritten a mc command, and i try to execute the command, it says that it's not a command. I printed the contents of knownCommands and I could not see any minecraft commands there by default. I'm confused as to why simply unregistering the command doesnt allow the vanilla functionality to return

[sterile token]

public void register() {
        try {
            for (Command command : this.commands) {
                if (!this.getCommandMap().register(this.plugin.getName(), command)) return;
                command.unregister(this.getCommandMap());
                this.getCommandMap().register(this.plugin.getName(), command);
                this.plugin.getLogger().info("[Core] Registered " + this.commands.size() + " commands");
            }
        } catch (Exception ex) {
            this.plugin.getLogger().severe("[Core] Failed to register commands. Reason: " + ex.getMessage());
        }
    }

    public void unregister() {
        try {
            for (Command command : this.commands) {
                if (!this.getCommandMap().register(this.plugin.getName(), command)) return;
                command.unregister(this.getCommandMap());
                this.plugin.getLogger().info("[Core] Unregistered " + this.commands.size() + " commands");
            }
        } catch (Exception ex) {
            this.plugin.getLogger().severe("[Core] Failed to unregister commands. Reason: " + ex.getMessage());
        }
    }


CommandMap getCommandMap() throws Exception {
        Field field = this.plugin.getServer().getClass().getDeclaredField("commandMap");
        field.setAccessible(true);
        return (CommandMap) field.get(this.plugin.getServer());```

[humble tulip]

yeah but let's say i register msg and then unregister, I dont get minecraft's msg command working again

[sterile token]

Oh minecraft command?

[humble tulip]

tried printing the contents of knownCommands but it's not there

[sterile token]

I never unregistered a minecraft command

[humble tulip]

you dont have to

it overwrites it iirc

[sterile token]

Oh ok

I didnt know

[alpine coral]

Is there a way to mass modify player NBT data?

I'd like to set all the players positions back to spawn

And so far

going through one by one

is gonna drive me mad

[humble tulip]

for loops?

are u doing it for a plugin or just wanna do it as a one time thing

[alpine coral]

One time thing

[humble tulip]

ah

are u a dev?

[alpine coral]

I can write up a script but if there's a tool already out there for it I'd rather do that

[humble tulip]

it's best u write a script

[alpine coral]

also I'm not sure how I would go about read/writing to it

[humble tulip]

might take as long as finding a plugin

it's pretty easy

[alpine coral]

as you can't even view it in visual studio code without an extension

[humble tulip]

want me to write something for u?

[sterile token]

Ima be wrong but intellij is shity today for me

[alpine coral]

that'd be gr8, but send source lol

thanks

[humble tulip]

dw i wont nuke ur server

[sterile token]

minion?

[humble tulip]

ye?

[sterile token]

Do you have any idea?

[alpine coral]

I mean its a fresh server atm so you'd be nuking a desert in equivalent

[humble tulip]

java version?

[alpine coral]

lol

[sterile token]

17

[humble tulip]

then idk

thought it was some weird thing

with java version in intellij being like version 7

that happens to me randomly

[sterile token]

Im uisng 17

Not Java 7

[humble tulip]

data is saved in world/playerdata right?

[alpine coral]

yea

[humble tulip]

finished it, just testing now

[alpine coral]

damn

[ornate patio]

more of a math question here

I'm looking at the NMS source code and I found the functions used to randomly generate horse speed, jump strength, and max health

why is this so weird though

and is it any different than what i have:

[sinful willow]

Is there a way to have custom blocks use custom textures kinda like how the wooden hoe trick works?

[river oracle]

yea just some texture pack finicky

it can take a bit to get everything going smoothly but its fun to screw around with that stuff

[ornate patio]

wtf is "RunAroundLikeCrazyGoal" lmao

[sinful willow]

would I just do the same trick as the wooden hoe or what? I'm not really sure how it'd work since blocks don't have durability in the way that tools do

[river oracle]

why would you use durrability

what version are you using

[loud junco]

probably when you hit a npc and it starts running around?

[sinful willow]

that's what's used for custom items. Not sure what the equivalent would be for blocks. I'm using 1.18.2

[ornate patio]

yeah its just a weird name

[loud junco]

🤷‍♂️

[river oracle]

no you don't have to use durability anymore thats pointless. I don['t think you've had to use durrability for a long while

Use ItemMeta#setCustomModelData

it takes in an integer and can be linked to resource packs

now you can have players use there tools like normal

instead of throwing away tools for an arbitrary purpose

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/inventory/meta/ItemMeta.html

[sinful willow]

I had been looking at this forum post:
https://www.spigotmc.org/wiki/custom-item-models-in-1-9-and-up/

[sinful willow]

Thx!

[crisp steeple]

lol

[humble tulip]

it is different

think of it like this

if u roll 2 6 sided die, the probability of outcomes is different to rolling one 12 sided

[ornate patio]

oh yeah i see

ima just copy paste the code from NMS then

[humble tulip]

they probably wanted some kinda variance

[ornate patio]

normal distribution?

[humble tulip]

where it's unlikely to get a fast or slow horse

that's not a normal distribution

[ornate patio]

roughly normal

i guess

[humble tulip]

yeah it's bell sahped for sure tho

doubt it's normal

[tawny otter]

for my Bungeecord Plugin
I got a purgatory list with many player uuids, any player that join the server whos on the list will be sent to the purgatory server
what would be the proper way of doing this

[humble tulip]

how large is the list?

[tawny otter]

should that matter?

[humble tulip]

well if it's a few players maybe store em in a file which you load on enable

and cache to a map/set

so u can check

if it's a lot of players, use a database and check the database when they join

[river oracle]

idk if its even necessary to cache if your immediatly redirecting them too be completely honest

[tawny otter]

Im more asking HOW I could send them to the purgatory server, not how I could check if they are in the list

[humble tulip]

so u dont load a file every time a player joins

[humble tulip]

https://www.spigotmc.org/wiki/sending-players-between-servers-in-bungeecord/

[tawny otter]

just player.connect?

[humble tulip]

yep

[tawny otter]

hmm, what join/login event can I use this in?

[humble tulip]

i think a few login events dont work

[tawny otter]

maybe the PostLoginEvent?

[humble tulip]

yeah try that

[harsh totem]

I have a JSONObject and when I write it to a json file it's all in one line.
is there a way to make each key and value in a separate line?

[humble tulip]

something with pretty

[tawny otter]

I was hoping I could re-route them before they joined the main lobby, like telling them to join the purgatory server in the first place

[humble tulip]

are u using gson?

[humble tulip]

postlogin is before they're connected to a server

[tawny otter]

I see

[humble tulip]

but after they login

[tawny otter]

alrighty, imma try that

[harsh totem]

json.simple

[humble tulip]

may i ask why not gson?

[river oracle]

GSON will have you covered with prettifying with Simple Json its all hacky methods

[harsh totem]

idk

[humble tulip]

isnt gson also in spigot by defualt?

[harsh totem]

it is

[river oracle]

alternatively if you're quirky you could use jackson

[river oracle]

https://stackoverflow.com/questions/4105795/pretty-print-json-in-java here is a resource on how to use the prettify from gson since I'm assuming your switching at this point

[harsh totem]

why switch?

[humble tulip]

Better json lib

No additional dependencies?

[harsh totem]

well i'll just backup my project and then try

[humble tulip]

Shouldn't be hard to swtich at all

[harsh totem]

wait but i have this private static JSONObject obj;.
what would it be in gson?

JSONObject is in json.simple

[river oracle]

in what world do you need a private static uninitialized JSONObject

do you have a static constructor?

[harsh totem]

it says 'JsonParser()' is deprecated

why?

what should i use instead?

[river oracle]

does it say why its deprecated

in the javadoc

[harsh totem]

No need to instantiate this class, use the static methods instead.

what does this mean

[river oracle]

Use JsonParser.parseString(java.lang.String)

found this in hte java doc

[humble tulip]

JsonObject convertedObject = new Gson().fromJson(json, JsonObject.class);

u can probably also do ^

[humble tulip]

this might be the ideal solution

[river oracle]

thats what Gson deprecated says to use instead of the deprecated JsonParser object

they changed to a static builder design

[harsh totem]

and in here file.write(obj.toJsonString());
how do I write this obj to the json file?
i have this also Gson gson = new GsonBuilder().setPrettyPrinting().create();

[humble tulip]

gson.toString maybe

I forgot

Haven't used anything with json in a while

Or maybe toJSonString

[harsh totem]

ok i got it

how do I get a JsonElement of an integer?

(the integer is not in the json file)

[minor otter]

anyone here know how I may be able to stop leaf blocks from updating the "Distance" blockstate?

[quaint mantle]

for what reason 🧐

[minor otter]

to stop the distance blockstate from updating 😂

nah but fr so I can add custom leaves

you can use blockstates to add models for specific distance blockstates on leaves

[quaint mantle]

makes sense

[minor otter]

sadly you can't just cancel blockphysics

[quaint mantle]

i guess whenever a leaves block decays

you can iterate the leaves attached

resetting them to their initial value

tho

i highly doubt this is efficient in large quanitites

[minor otter]

the value doesnt just change when a leaf block decays

and I feel it wouldn't be efficient to search through every leaf block everytime a player places any log near them

I tried searching online but I wasn't able to find anything

apparently not a common issue. 😅

[harsh totem]

it says I can't do JsonObject.add(String, int) because obj is null (has nothing in it).
how am I supposed to add anything to it?

[proper notch]

PostLogin is initialised before your instance variable is set.

You should avoid abusing static like this and follow a dependency injection structure.

[tawny otter]

just following a tutor

[river oracle]

?di

[undone axle]

Guide to dependency injection: https://www.spigotmc.org/wiki/using-dependency-injection/

[tawny otter]

so I pass the plugin in the registerListener?

getProxy().getPluginManager().registerListener(this, new PostLogin(this));

and

private Purgatory plugin;

public PostLogin(Purgatory plugin) {
    this.plugin = plugin;
}

like so?

[river oracle]

yes

[harsh totem]

any ideas?

[river oracle]

you should pass most things like this excluding utility classes

[tawny otter]

neat, thanks = )

works on the first time, nice

[river oracle]

little hint with DI is when making Util classes that require a JavaPlugin param you can actually pass in the generic JavaPlugin versus your instance Purgatory which will make your utils much more portable

this works because of polymorphism and is just a neat tip you should know

[harsh totem]

anyone?

[tawny otter]

thats gonna be helpful

[desert loom]

what is obj?

[harsh totem]

JsonObject

[proper notch]

Can you show your code please

[desert loom]

did you initialize the JsonObject?

[harsh totem]

    public void badOmen(RaidTriggerEvent event){
        JsonElement element = JsonParser.parseString(String.valueOf(event.getPlayer().getPotionEffect(PotionEffectType.BAD_OMEN).getAmplifier()));
        obj.add(event.getRaid().getLocation().toString(), element);```

[desert loom]

there's no initialization for obj in that code

are you sure you didn't forget to initialize obj

[harsh totem]

private static JsonObject obj;

it not in the function

[quaint mantle]

where is obj assigned a value

[harsh totem]

here

I want to add a key and a value

[quaint mantle]

hey, im gonna create a variable but assign no value to it

[harsh totem]

??????

[quaint mantle]

whats this? i cant use my variable because it has no value?!?!?

[harsh totem]

I WANT TO ADD VALUE
why are you being rude

[quaint mantle]

that's considered being rude?

[desert loom]

you need to set obj to a new JsonObject or however you create one of those.

Ny will probably be nice

[river oracle]

NY has lots of agriculture

I have this private static JsonObject obj = new JsonObject();
and this is where i add value: JsonElement element = JsonParser.parseString(String.valueOf(event.getPlayer().getPotionEffect(PotionEffectType.BAD_OMEN).getAmplifier())); obj.add(event.getRaid().getLocation().toString(), element);
and this is where i get the value: try (Reader reader = new FileReader(plugin.getDataFolder() + File.separator + "data.json")) { JsonObject jsonObject = (JsonObject) JsonParser.parseReader(reader); return jsonObject.get(key).getAsInt(); } catch (IOException e) { e.printStackTrace(); }
Why does it say java.lang.NullPointerException: Cannot invoke "com.google.gson.JsonElement.getAsInt()" because the return value of "com.google.gson.JsonObject.get(String)" is null?

Here are some links to get you started on learning Java:

• https://www.codecademy.com/learn/learn-java
• https://www.sololearn.com/learning/1068
• https://www.learnjavaonline.org/
• https://programmingbydoing.com/
• https://docs.oracle.com/javase/tutorial/java/index.html

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