IDK IM STUPID OKAY 😭

[lost matrix]

You are not. Its not something you cant do because of intelligence but because of knowledge. Big difference.

[red sedge]

and well um... the unwillingness to learn that knowledge

[river oracle]

7smile7 out here with the wise words

[lost matrix]

For a circle its even simpler because spigot already has methods that let you rotate a vector around an axis.

[red sedge]

i feel like going from 2d to 3d i know absolutely nothing

[river oracle]

2d is like 3d but you multiply height for 3d

[grim ice]

stuff like this u just copy paste from google my friend

even if u know how to do it i cant be bothered to

[lost matrix]

  public List<Location> horizontalCircleAround(Location center, double radius, int points) {
    List<Location> locations = new ArrayList<>();

    Vector cursor = new Vector(radius, 0, 0);
    double deltaPhi = (2 * Math.PI) / points;
    for (int i = 0; i < points; i++) {
      locations.add(center.clone().add(cursor));
      cursor = cursor.rotateAroundY(deltaPhi);
    }

    return locations;
  }

[red sedge]

i mean yeah that is pretty 2d still

i can do thart

[lost sedge]

What do I use instead of ChatComponentText in 1.19

[lost matrix]

Look at this package:
https://nms.screamingsandals.org/1.19/net/minecraft/network/chat/index.html

[lost sedge]

Thanks

[lost matrix]

FormattedText.of()

[lost sedge]

yeah this doesn't work

[quaint mantle]

Okay so I'm making a plugin right now about Ranks, and I need help about the permission part.

I wanna use "parents", and the problem is idk how to loop thru the ranks untill the rank has no parent.

[chrome beacon]

Component.literal()
Is this what you want??

[simple silo]

java.util.UnknownFormatConversionException: Conversion = '%'
huh? it breaks my AsyncPlayerChatEvent listener

[viral pike]

Hello I have a question for the performances

Is looking at a player’s coordinates all the time really advisable ?

[chrome beacon]

Depends on what you're making

[viral pike]

I want to see if any players are approaching the coordinates on their teleport

[chrome beacon]

Then yeah you will have to track player movement

You can minimize lag by only tracking players in a specific world and using the scheduler instead of a movement listener

[viral pike]

But I should still put it in an event, right?

[chrome beacon]

No

Just use the scheduler to check every few ticks

?scheduling

[undone axle]

https://www.spigotmc.org/wiki/scheduler-programming/

[viral pike]

Okay thank u ❤️

[lost sedge]

im trying to find something to replace this from what I used in 1.18.2
new ChatComponentText(this.d().a())

[chrome beacon]

Yeah Component.literal would be that in 1.19 mojmaps

[lost sedge]

hmm because thats not showing up as like an option

[chrome beacon]

Are you using Mojmaps

You should be

[lost sedge]

no just spigot

[chrome beacon]

It's annoying to have method names like a()

Why make it hard for yourself

[lost sedge]

its more like im updating someone elses code

its an nms thing

[chrome beacon]

Then add mojmaps to the project

[lost sedge]

yeah whats the repo?

[chrome beacon]

https://blog.jeff-media.com/nms-use-mojang-mappings-for-your-spigot-plugins/

[lost sedge]

thanks

[chrome beacon]

Replace 1.18.2 with 1.19 and update special source to 1.2.4

[heavy marsh]

Hi, what is the updated way to check if an ItemStack is dye and get the DyeColor for that dye? Don't want a massive switch statement checking all 16 dyes

[worldly ingot]

You're gonna have to use the switch statement

Else you can create a Map but tbh, the switch statement might actually be faster lol

[lime moat]

Hello, how could I make my tab completer have online players? java public class GamemodeSurvival implements TabExecutor { private static final String[] COMMANDS = {"players"};

[heavy marsh]

is there no replacement for the MaterialData Dye?

[worldly ingot]

No because they're all separate materials now

[heavy marsh]

I saw..

[worldly ingot]

You can return null in the tab completer and it will default to player name tab completion

[lime moat]

How may I return null?

[worldly ingot]

public static DyeColor getDyeColor(ItemStack itemStack) {
    return switch (itemStack.getType()) {
        CASE RED_DYE -> DyeColor.RED;
        CASE BLACK_DYE -> DyeColor.BLACK;
        // etc.
        default -> return null;
    }
}```

Just a good ole static util method is good enough

[lime moat]

private static final String[] COMMANDS = null; just this?

[river oracle]

why is it static?

[worldly ingot]

No. In your onTabComplete()

[worldly ingot]

because it's a utility method

[river oracle]

mb thought it was public for a second

[heavy marsh]

and this'll be good for checking right? item.getType().toString().endsWith("_DYE")

[worldly ingot]

I mean... I'd avoid it

[heavy marsh]

ok, util it is

[worldly ingot]

It's like 20 lines of code ;p It's really not bad

[river oracle]

I'm surprised there is no DYE tag

[lime moat]

Sorry, I'm still very confused with the null thing. I currently have java @Override public List<String> onTabComplete(CommandSender sender, Command command, String alias, String[] args) { return null; }

[river oracle]

thats exactly how you do it lol

just return null

[lime moat]

Block block = event.getClickedBlock();
if (block == null || !block.getType().equals(Material.CAULDRON)) return;

Levelled cauldron = (Levelled)block.getBlockData();

getting CraftBlockData cannot be cast to class Levelled anyone know why?

Surely it should be able to be cast since Levelled extends BlockData

[quaint mantle]

If I did Mob mob = (Mob) event.getRightClicked(); How would I get the whole Mob type based off of event.getRightClicked() off of PlayerInteractEntityEvent instead of just that specifically clicked Mob

[lost matrix]

What do you mean by "whole Mob type"?
You can get the type of an entity by calling

EntityType type = entity.getType();

[lost matrix]

A cauldron has no level until it contains something.
At that point it is either of type WATER_CAULDRON or LAVA_CAULDRON

[heavy marsh]

oh

thanks

[quaint mantle]

Why won't my PlayerInteractEntityEvent ever fire

[lost matrix]

When do you expect the event to fire?

[quaint mantle]

When they right click an entity

[lost matrix]

Did you forget to register the listener?

[quaint mantle]

I'm going to kill myself

[lost matrix]

Dont. Thats a classic one.

[ancient plank]

[heavy marsh]

Looking for some advice, so: I have a resource web server that has all the resource packs that my plugins use, this server when requested will combine all of the resource packs needed for a server given the plugins that are installed. Each player has their resource pack set through Player#setResourcePack where the url is the one that will return the combined resource pack, however if I make changes to any of the packs it won't update without deleting server-resource-packs. How would I either: get the sha1 from the resource server to pass into the method, or, generate a sha1 within the plugin for the resource pack sent?

[lost matrix]

Been there. My solution was to create a folder with the current unix timestamp as a name (1656715872 for example) every time when the server starts.
And assemble the resourcepack in there.

This however means that the user will have to download a new resourcepack after each restart.

[heavy marsh]

this was the thing I didn't want to do

[lime moat]

How could I check a player's gamemode?

[lost matrix]

Me neither. But for some reason the hash just wouldnt be enough to force an invalidation....

[lost matrix]

Player#getGameMode()

[heavy marsh]

so even if I sent another web request to the web server to get the sha1 and pass that into the method it could still not be enough?

[lost matrix]

For me it wasnt.

[quaint mantle]

mobbystick.setDisplayName(ChatColor.translateAlternateColorCodes('&', "&6Mob Stick"));
            mobbystick.addEnchant(Enchantment.PROTECTION_FALL, 1, true);
            mobbystick.addItemFlags(ItemFlag.HIDE_ENCHANTS);
            mobstick.setItemMeta(mobbystick);
            player.getInventory().addItem(mobstick);

So I created an item meta for a Mob Stick that I need to use but whenever I check in my Listener, I use if (item == mobstick) and it never works even though that's the item I'm holding. (The variable item is the item in Player's main hand that's already working). How would I get it to work or how would I check to see if it's the mob stick?

[lost matrix]

But that was back then for 1.16

[quaint mantle]

Console prints this

ItemStack{BLAZE_ROD x 1, UNSPECIFIC_META:{meta-type=UNSPECIFIC, display-name=º6Mob Stick, enchants={PROTECTION_FALL=1}, ItemFlags=[HIDE_ENCHANTS]}}

[compact haven]

the hash should be generated on the resource server, then held in a file within the pack & available from the zip directory

so like packs/yourpack.zip & packs/yourpack.sha1

[lost matrix]

== checks for identity (if they have the exact same memory address)
You should never use it unless you are comparing primitives or Enums.

Also: For custom ItemStacks always use the PersistentDataContainer of the ItemStack

?pdc

[undone axle]

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

[compact haven]

and 7smile, are you positive the hashes were different?

if the hash is the same it'll use the old version

never tested it myself but just seems illogical

[lost matrix]

I just remember that for some reason the client wouldnt want the new resourcepack even when i made changes
and recalculated the hash. But that was 2 years ago and i only had like 6 months of programming experience so who knows.

[compact haven]

ah interesting

[echo basalt]

^ FYI, using == for enums is fine because their memory addresses are linked to their ordinal() position, so == automatically checks one.ordinal() == two.ordinal()

[heavy marsh]

storing the sha1 in the .zip, how would I access that sha1 without complicating the plugin side?
This is my current plugin-side:

String resources = ResourceManager.getResources();
player.setResourcePack("http://ADDRESS/spigot-resource-combine?resources=" + resources, null, true);

[echo basalt]

ZIP files are openeable via code, rar are not

[compact haven]

well no, I wouldn't advise unpacking the zip for the hash

that was just for the client incase they wanted to compare, but on second thought you can't really calculate a hash of the zip without adding the file, but then you can't ad dthe hash

[lost matrix]

I dont get why you would need a hash file... why cant you just lazily calculate it once on the first request?

[echo basalt]

I wonder if it's possible to make a function that predicts its own hash

[compact haven]

sure, but then the server needs to download the zip & calculate for each combination

[heavy marsh]

hashes are unpredictable, that is the whole point of a hash

[echo basalt]

Like I always imagined a class that could have unbreakable DRM because it would store its own hash and compare it

[compact haven]

Maybe it is the servers job to calculate the hash

and it’s only once on load

it’s really up to you how you want to design it

[lost matrix]

Only makes sense if you provide the web server yourself... thats what i did. The plugin had the resourcepack sources in it.
Then on startup it assembled a resourcepack, started a web server and provided it.

[heavy marsh]

interesting, not sure if putting the resource packs in the plugin is great since that means a new plugin version is needed for every resource pack change

[lost matrix]

That was not a real problem really. The resourcepack was tightly coupled with the code. We had compile time checks for the resourcepack.

[heavy marsh]

ic

[lost matrix]

This allowed for dynamic texture generation. We had every single texture as a font character as well.

[heavy marsh]

Not sure if I quite want to go that elaborate

But sounds very powerful

[lost matrix]

Man i miss some of the stuff i made back then. Was really pushing what you could do without mods...

[sand vector]

I have a hologram using armorstands, but I need to make a part change each second. Do I remove the hologram and then replace it or can I rename it?

Also 7smile7 thats sick

[spring minnow]

i have a boss plugin and i want to make player death message display boss name instead of entity name when boss kills him

in the player Death event i can't get the entity who killed the player that's the issue

[heavy marsh]

Ok, here is my solution. The resource web server keeps a cache of the combined resource pack buffers and another cache for the sha1's, a sha1 will be generated using the buffer if it is not in the cache. The manager plugin then makes a request to the web server, which sends the sha1 as base64, this then gets decoded and passed into the Player#setResourcePack method.

String resources = ResourceManager.getResources();
String packUrl = "http://ADDRESS/spigot-resource-combine?resources=" + resources;

byte[] sha1 = null;
try {
    URL url = new URL(packUrl + "&sha1=true");
    HttpURLConnection connection = (HttpURLConnection)url.openConnection();
    connection.setRequestMethod("GET");

    int status = connection.getResponseCode();
    if (status < 300) {
        BufferedReader receive = new BufferedReader(new InputStreamReader(connection.getInputStream()));
        sha1 = Base64Coder.decode(receive.readLine());
        receive.close();
    }
    connection.disconnect();
} catch (Exception err) {
    err.printStackTrace();
}
player.setResourcePack(packUrl, sha1, true);

It does work in getting the client to download a new version of the resourcepack, however it doesn't then load that new pack unless the player rejoins.

It sends this request for every player since the resourcepacks might have changed (though this does mean current players may have different packs but I don't think this matters since new content cannot be added without a server restart)

[sinful rapids]

how do i like:
if the player has cobblestones in his hand;

[mortal hare]

i had never realised anvils can be renamed

[spring minnow]

they extend to inventory soo

[mortal hare]

not all inventories are renameable

even if they extend inventory

[spring minnow]

really?

[mortal hare]

due to how client handles them

[spring minnow]

oh

[mortal hare]

for example cartography table cant be renamed iirc

[heavy marsh]

doesn't seem to work for me on 1.19

[mortal hare]

https://i.imgur.com/93zY3Iw.png

nvm

it works

oh boy

how this one thing

will change my api for good

i thought some GUIS are not renameable just because they are not renameable via the anvil

it seems all inventories are renameable except client ones (player, crafting player, etc.)

Man I was trying to build something which doesnt exist

but not in the anvils

If you have a question, please just ask it. Don't look for staff or topic experts. Don't ask to ask or ask if people are awake or available. Just ask the question to the channel straight out, and wait patiently for a reply. Make sure you use the right channel regarding the topic of your question. Create a thread in case the channel is already in use!

[nocturne cedar]

well I didn't know if it had to be explicitly spigot related

anyways

this is the line i'm having trouble with:

this.brokenBlocks = (Multimap<String, Location>)ArrayListMultimap.create();

and this is the error I'm getting:

Cannot cast from ArrayListMultimap<Object,Object> to Multimap<String,Location>

here's the whole java file if needed

[eternal oxide]

So this is decompiled code?

[nocturne cedar]

well it was open source at one point

the guy deleted his github though, and I couldn't find the source

the plugin's from 2014, but still works

so that's why I'm using it

[lime moat]

I'm quite new to java, how would I make java sender.sendMessage(MiniMessage.miniMessage().deserialize(prefix_message + ' ' + gms_other, Placeholder.component("player", Component.text(target)))); target work here?

It's supposed to be a string, but I just need target there.

[eternal oxide]

It has to be a decompiler error. I see no reason its trying to cast an ArrayListMultimap to a MultiMap

[nocturne cedar]

damn

[eternal oxide]

Just try java this.brokenBlocks = ArrayListMultimap.create();

it shoudl not need any cast

[nocturne cedar]

[minor otter]

is it possible to run particles along a raytrace

[analog whale]

the whole premise of this server is helping others which i see is quiet nice, but im still new so i've not seen the bad side :0

[lost matrix]

You can march the ray along by stacking up small vectors

[minor otter]

any public discussions about doing this you are aware of?

[lost matrix]

I can give you a kick start

[minor otter]

that'd help

[lost matrix]

  public List<Location> march(Location location, Vector direction, double distance, double delta) {
    List<Location> path = new ArrayList<>();
    direction.normalize().multiply(delta);
    int steps = (int) (distance / delta);
    for(int i = 0; i < steps; i++) {
      path.add(location.add(direction).clone());
    }
    return path;
  }

With this you can specify a location, a direction, how far you want to march and which distance
you want to have between each step.

[minor otter]

sick dude, thanks alot 😄

[lost matrix]

This however does not stop when a block or entity is hit.

Do you need that? Because then you would have to do small ray traces between each point.

[minor otter]

I do want that

[lost matrix]

To be honest i would actually just ray trace from A to B, get the distance and direction between those two points
and then use the method above to draw a line between them.

[minor otter]

alright that makes sense to me

thanks

[lost matrix]

This should actually do it

  public List<Location> march(Location location, Vector direction, double distance, double delta) {
    List<Location> path = new ArrayList<>();
    direction.normalize().multiply(delta);
    int steps = (int) (distance / delta);
    for(int i = 0; i < steps; i++) {
      path.add(location.add(direction).clone());
    }
    return path;
  }

  public List<Location> marchTrace(Location location, Vector direction, double maxDistance, double delta, RayTraceResult rayTrace) {
    if(rayTrace == null) {
      return march(location, direction, maxDistance, delta);
    }
    Vector hitVec = rayTrace.getHitPosition();
    double hitDistance = hitVec.subtract(location.toVector()).length();
    return march(location, direction, hitDistance, delta);
  }

You just need to decide what to do with null ray traces. Either march to max or do nothing.

[minor otter]

sick dude thanks so much for the help this makes things infinitely easier

[undone ruin]

How do I make a Vector "point/aim" to a location?

[lost matrix]

Assuming you have two locations A and B, then you can define a vector from A->B by
subtracting A from B.

So
B.subtract(A)

[lost matrix]

    Location base = ...;
    Location target = ...;
    Vector direction = target.toVector().subtract(base.toVector());

but I also quite didnt understand wym by this:

just without the coordinates bit

so like

you would be able to do

/rotation @p facing entity @r feet

like that

or /rotation @p 0 90

AAAAAAAAAAAAAAA

[glass mauve]

[river oracle]

cope

[ruby swift]

squid

[glass mauve]

didnt know this cmd exist

[ruby swift]

do you know "basic java"

[glass mauve]

yea

[river oracle]

do you know basic java?

[glass mauve]

yea thats the actual question

[river oracle]

Also I like how he said do it for free and donate you cash in the same sentence

like its not completely contrary

[glass mauve]

lmao

[lime moat]

How could I get a player's max health into a variable?

[lost matrix]

double maxHealth = player.getAttribute(Attribute.GENERIC_MAX_HEALTH).getValue();

[eternal oxide]

    public void setFacing(Player player, Location target) {
        
        Location loc = player.getLocation();
        Vector direction = target.toVector().subtract(loc.toVector());
        
        loc.setDirection(direction);
        player.teleport(loc);
    }```

[ruby swift]

you might as well be talking to me in italian

[eternal oxide]

give that to whoever you get to write your plugin

it will make a Player face teh location you provide

[ruby swift]

wait

i need it to work like

/rotation @p facing entity @e feet

like that

wait

[eternal oxide]

Yep, the command is the easy bit

The code I just gave you is where most devs will get stuck

[ruby swift]

oh

[ancient plank]

math is hard

[ruby swift]

hey @ancient plank

[lime moat]

How could use an if check to determine if a player's flight is enabled/disabled?

[summer scroll]

Player#getAllowFlight

[lime moat]

Thank you very much!

[boreal seal]

hey guys

[glass mauve]

hi :D

[boreal seal]

i run into an issue

an unique one

i read the docs and etc

but it just dont work

[glass mauve]

what are you trying to do

[boreal seal]

event.setFormat

from ASyncChatEvent

now i even went maniac mode after 2 hours and decomplied half of the plugins on spigot

and they didnt do anything different from mine

[glass mauve]

paper ig?

[boreal seal]

why when i do it just doesnt work?

ig.equals?

[glass mauve]

i guess

[boreal seal]

no i use normal spigot

not a fork out of spigot

i tested other plugin

and it worked

[glass mauve]

there is no ASyncChatEvent in spigot

only AsyncPlayerChatEvent

AsyncPlayerChatEvent is deprecated in Paper, bc you should use AsyncChatEvent

[boreal seal]

oh i cant send pictures

[glass mauve]

np I saw it

[boreal seal]

so

[glass mauve]

yeah you use Asyncplayerchatevent, but said AsyncChatEvent

[boreal seal]

i need to implement a library?

[glass mauve]

there is a difference

[boreal seal]

hm ll try to use them both

i have no idea what the other event does then

[glass mauve]

the other event doesnt exist in Spigot

so you dont need to care about it

but I thought that you use Paper instead of Spigot bc you said you use AsyncChatEvent which only exists in Paper

[boreal seal]

oh

i mean like what did i do wrong there?

[glass mauve]

whats happening and what should happen

[subtle folio]

?paste your code

[boreal seal]

it should be the format

[undone axle]

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

[boreal seal]

i realized

i think its all because i missed @EventHandler

lmao

[glass mauve]

💀 💀 💀 💀

[boreal seal]

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

[subtle folio]

gg

[boreal seal]

but ill test it now

i spend on it

so many hours

so many

i decomplie so many resources to see how they done it

and it was the saem

like

.

[subtle folio]

did you register i

it

[glass mauve]

oof that hurts

[boreal seal]

ofcourse Ntdi

[glass mauve]

"ofcourse"

[boreal seal]

the thing in the same class i have more 20 listeners + -

[glass mauve]

but forgot EventHandler 👀

[boreal seal]

the rest did work

[subtle folio]

lmao

imagine not diff class for each listener 🤓

[boreal seal]

it really depends on what i do sometimes i put all of them in a single class

some times in sperate

but i dont go all in into mainclass

lol

[glass mauve]

I always make a new class for each listener, but sometimes 2-3
never used 20 in one class

[boreal seal]

idk whats the problem of doing it

[subtle folio]

reminds me of using if else for each of ur commands in the same class

[subtle folio]

it’s just messy and hard to maintain

[glass mauve]

yea lmao

[boreal seal]

just do control+F

[subtle folio]

kinda frowned apon in spigot

[boreal seal]

and find quickly what i need

[subtle folio]

okay bro

[boreal seal]

like i know eyes will hurt

but all the 20 events have a common goal

beside the chat events

[stoic vigil]

commandexecutor --> gets called correctly but the item frame doesn't gets deleted

public class ConfirmDeletePosterCommand implements CommandExecutor {
    @Override
    public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
        World world = sender.getServer().getWorld(args[3]);
        Location location = new Location(world, Double.parseDouble(args[0]), Double.parseDouble(args[1]), Double.parseDouble(args[2]));
        Collection<Entity> entities = world.getNearbyEntities(location, 0,0,0);
        for (Entity entity : entities) {
            if (entity instanceof ItemFrame) {
                entity.remove();
            }
        }
        return true;
    }
}

itemframe break listener --> only possible problem

public class PosterBreake implements Listener {
    @EventHandler
    public void blockBreak(HangingBreakEvent e) {
        if (e.getCause() == HangingBreakEvent.RemoveCause.DEFAULT) { return; }
        e.setCancelled(true);

        Entity entity = e.getEntity();
        Location location = entity.getLocation();
        Collection<Entity> entities = location.getWorld().getNearbyEntities(location, 10, 10, 10);
        for (Entity nearbyEntity : entities) {
            if (nearbyEntity instanceof Player) {
                nearbyEntity.sendMessage("§cDo you really want do destroy this mapart?");
                TextComponent clickableYes = new TextComponent("[Yes]");
                clickableYes.setClickEvent(new ClickEvent(ClickEvent.Action.RUN_COMMAND, "/confirmdeleteposter %d %d %d %s".formatted(location.getBlockX(), location.getBlockY(), location.getBlockZ(), location.getWorld().getName())));
                nearbyEntity.spigot().sendMessage(clickableYes);
            }
        }
    }
}

thx already for helping!

[subtle folio]

?paste

[stoic vigil]

sry

[boreal seal]

i would say this format way better then the paste one

[subtle folio]

no

floods chat 😦

[stoic vigil]

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

[glass mauve]

not if you select correct programming language

[subtle folio]

whats the problem?

[stoic vigil]

it looks exactly the same, so flooding chat is the only argument

[glass mauve]

yea and makes sense

[stoic vigil]

read comments 😉 thats the reason i wrote it here

[subtle folio]

its a valid argument

[glass mauve]

also you need to scroll after a while to get back to your code/read messages

[stoic vigil]

yee, ik, just didn't remember the rule here 🙂 i'll remember next time

[subtle folio]

do you have a proper argument check?

like args[0-3] ?

[stoic vigil]

nope, but the arguments are correct

[07:59:54] [Server thread/INFO]: Schwerthecht issued server command: /confirmdeleteposter 112 66 -59 world

[subtle folio]

lickEvent.Action.RUN_COMMAND, "/confirmdeleteposter % no /

oh wait

its working?

oh wait i see

[stoic vigil]

yee, command is executed correctly

[subtle folio]

some weird way of doing it

ok

[stoic vigil]

how to do better? ^^

[subtle folio]

print out all the Collection<Entity> entities = world.getNearbyEntities(location, 0,0,0);

[subtle folio]

calling a command is kinda silly but im on a phone so I cant really write up a better way

ig for u its fine

i just didnt understand

[stoic vigil]

idk how to react in an other way to clickable text... so pls let me now, if you're at home

[stoic vigil]

so if i have 0,0,0 it finds none, but with 1,1,1 it also finds the ones around it xD maybe 0.5,0.5,0.5 works?

[subtle folio]

shrug idk man

locations are weird

u could try uping the radious

radius*

[stoic vigil]

okee ^^ so i'll try 0.5, thy! ❤️

[humble tulip]

Why u wanna do 0,0,0?

That's a volume of 0

You can't have anything in nothing

Ur removing itemframes?

[stoic vigil]

jee, that makes sense, but with 1 it deletes all around too

[humble tulip]

Why just around the player may i ask?

[stoic vigil]

correct

[stoic vigil]

it isn't around player, it's around a location

[subtle folio]

a command gets called from the event of breaking itemframes ^

confused me aswell

[stoic vigil]

i just want a clickable text confirmation and you just can react in code to this with a command (afaik)

[humble tulip]

Yeah

Makes sense

[stoic vigil]

just cant find the issue 😭

[undone temple]

Why PlayerItemConsumeEvent when using potion returns in the method "getReplacement()" null?

i need replace GLASS_BOTTLE when player use potion

@alpine urchin can u help me?

[chrome beacon]

Well that's a random ping

[vocal cloud]

That's why you don't put your GitHub in your bio /s

[alpine urchin]

@md5 can you help me

[vocal cloud]

Get pinged

[torn oyster]

how should i use OOP to get the most efficient sql connection and usage

[grand glade]

It’s impossible to contact him, that’s my experience 😀

[torn oyster]

rn i am creating one called "SQLSetup" and one called "SQLUtil" but i don't know if that is the best (SQLSetup is for establishing the connection and basic queries and SQLUtil is a class full of queries that i use often)

[grand glade]

Using singletons is always the best approach to minimize useless resource requirements

[subtle folio]

thats what I use

[subtle folio]

we've emailed before, not that impossible.

[grand glade]

Then you’re lucky or more than me 😀

I sent him a mail but didn’t get any reply

[subtle folio]

is it possible to get a method from a string

like rs.get + "kills"() or rs.get + "deaths"()

or is valueOf only an enum thingy

uses refliction https://stackoverflow.com/questions/160970/how-do-i-invoke-a-java-method-when-given-the-method-name-as-a-string

ig no easy way

[torn oyster]

i think you could do getStat(Enum)

[subtle folio]

its not an enum 😦

[torn oyster]

instead of getKills() and getDeaths() being separate

[torn oyster]

you could do strings as well

using a switch statement in getStat

[subtle folio]

its more of a getInt() and getFloat() that im tryna combine two functions into one

[torn oyster]

hm

you could make getStat return an object and use instanceof and casting

[subtle folio]

private static int getInt(String name, ResultSet rs) {
        try {
            int num = rs.getInt(name);
            rs.close();
            return num;
        } catch (SQLException e) {
            e.printStackTrace();
        }
        return 0;
    }

    private static float getFloat(String name, ResultSet rs) {
        try {
            float num = rs.getFloat(name);
            rs.close();
            return num;
        } catch (SQLException e) {
            e.printStackTrace();
        }
        return 0;
    }```

if you wanna see the code 😛

[torn oyster]

ah i see

[subtle folio]

ooo maybe

[subtle folio]

beautiful, ```java
private static int getInt(String name, ResultSet rs) {
return (int) getObject(name, rs)
}

private static float getFloat(String name, ResultSet rs) {
    return (float) getObject(name, rs);
}

private static Object getObject(String name, ResultSet rs) {
    try {
        Object obj = rs.getObject(name);
        rs.close();
        return obj;
    } catch (SQLException e) {
        e.printStackTrace();
    }
    return 0;
}```

[humble tulip]

Resultsets close with the statement iirc

[subtle folio]

Wdym?

like i dont need a rs.close()?

[humble tulip]

Nope

As long as the statement is closed

[subtle folio]

i read on a forum that it was better practice to keep it

[humble tulip]

No

[subtle folio]

but that brings down alott of the lines

so thank you ❤️

@humble tulip what are your thoughts on this code? java public static boolean isInDatabase(UUID uuid) { try { ResultSet rs = stmt.executeQuery("SELECT * FROM STATS WHERE ID='" + uuid.toString() + "';"); if (rs.next()) { return true; } } catch (SQLException e) { e.printStackTrace(); } return false; }

[humble tulip]

What's the point in checking if it exists?

Like specifically

It's fine tho

[grand glade]

What is the result if you run a query and there is not result for it? I think you get and exception or maybe null, so you could check for those

[humble tulip]

There will be no next so retun null

[grand glade]

Maybe some misunderstanding 🙂
You could also check that there is any existing result matching to the query, you check is the result null or maybe the size of the result also could help

Oh and one more trick, in most cases there isn’t required to use the semicolon on the end of the query

[subtle folio]

I shouldn't do mysql thingys on the main thread, right?

[humble tulip]

Nope

You should not

[subtle folio]

got it 😛

Should I make a new connection each time I want to update smt in the sql db or do I just keep one alive?

[humble tulip]

Do u use hikari?

If not, keep one connection

[subtle folio]

Postgres

[tardy delta]

Connectionpool like hikaricp ^^

[subtle folio]

what?

[flint coyote]

Hikari creates and handles a connection pool. It is not a database. It handles the pool and hands you an open connection when you need one

[subtle folio]

UUID uuid = UUID.fromString("e985173d-f10f-4bc0-95cc-613cd49e5573");

the bc0 is in the middle

[river spear]

Why do I get null entity with this one Entity entity = player.getTargetEntity(10); when this player of target is in creative mode?

[chrome beacon]

That's not Spigot API is it?

[summer scroll]

Also @subtle folio check out try-with-resources.

[opal juniper]

this is paper api and that just means there is no targeted entity within the range 10

[river spear]

oh okay thanks

[rotund pond]

Hey everyone !
I'm trying to check if a player is vanished (using Essentials, so using Player#hidePlayer method), but I can't find out how ...
Does anyone know something about it please ? 🙂

[next stratus]

It might be worth having a look in the com.earth2me.essentials.User class of essentials

[rotund pond]

I was wondering if I can do it without essentials API, so I won't depend on this plugin specially

[quaint mantle]

where did u guys learn coding?

[next stratus]

https://github.com/EssentialsX/Essentials/blob/2.x/Essentials/src/main/java/com/earth2me/essentials/User.java#L680?

[next stratus]

Self taught, practice and failing

[rotund pond]

I'm french so I used this at first: https://koor.fr/Java/Tutorial/Index.wp
For english speakers, there's things like this

[next stratus]

I'd advise learning object oriented programming aka OOP first before learning spigot big mistake me not learning that first

[quaint mantle]

public class TeleportBow implements Listener {
public void whatever(ProjectileHitEvent event) {
if (event.getEntity().getShooter() instanceof Player) {
Player player = (Player) event.getEntity().getShooter();
if (player.getInventory().getItemInMainHand().getType().equals(Material.BOW)) {
if (event.getHitBlock() == null) {
player.teleport(event.getHitEntity());
} else if (event.getHitEntity() == null) {
player .teleport(event.getHitBlock().getLocation().add(0,1,0));
}
}
}
}
}

how can i add recipe

[rotund pond]

Wdym ?
Recipe for what ?

[quaint mantle]

for the teleport bow

i made teleport bow but idk how can i make it craftable

[rotund pond]

This https://www.spigotmc.org/wiki/recipe-example/ ?

[quaint mantle]

wait

i know that

i know how to create recipes

[rotund pond]

😅

[quaint mantle]

but i want to add the recipe into this code

[quaint mantle]

its ok if you dont know

[rotund pond]

I don't understand you request tbh
Why would you add a recipe in this code ?
It's just a listener, there's no point in using a recipe
So I don't know how I could help you

[quaint mantle]

listen.

i want to make it craftable

[rotund pond]

Ah I know how I could: You should use early returns to make your code easer to maintain

[summer scroll]

Player#canSee

[quaint mantle]

so people can craft it

[rotund pond]

Thank you, that's what I was looking for 👍

[quaint mantle]

i want the teleport bow to be craftable so people can craft it but i dont know how to make it

[rotund pond]

Yeah so that's what I've sent to you : https://www.spigotmc.org/wiki/recipe-example/
By creating a custom recipe, players can craft your item

[quaint mantle]

yesssssssssssssssssssssssssssssssssssssssss

i know that

[rotund pond]

🤨

[quaint mantle]

but i want the way to make THIS code as recipe

public class TeleportBow implements Listener {
public void whatever(ProjectileHitEvent event) {
if (event.getEntity().getShooter() instanceof Player) {
Player player = (Player) event.getEntity().getShooter();
if (player.getInventory().getItemInMainHand().getType().equals(Material.BOW)) {
if (event.getHitBlock() == null) {
player.teleport(event.getHitEntity());
} else if (event.getHitEntity() == null) {
player .teleport(event.getHitBlock().getLocation().add(0,1,0));
}
}
}
}
}

please anser my qestion

[rotund pond]

But this code isn't a recipe

This code is a Listener

[quaint mantle]

extends JavaPlugin ?

[rotund pond]

You can't make a cat barking, as much as you can't transform a Listener in a recipe

[mortal hare]

🙃

[rotund pond]

Did you learn Java ?

[quaint mantle]

oh ok

hm

am new

idk

lol

[rotund pond]

Aaah

[quaint mantle]

just coding for my smp

[rotund pond]

So you should learn OOP first, before trying spigot

[mortal hare]

Composition or Inheritance hmm

[quaint mantle]

u have video tutorial

[rotund pond]

You will earn so much time

[quaint mantle]

i need a tutorial

[rotund pond]

If we could learn everything with videos, university wouldn't exist

[quaint mantle]

so how can i learn java

[glossy venture]

?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.

[glossy venture]

some good resources

[quaint mantle]

thx

i will check it out

[mortal hare]

well I learnt 80% of Java just from the internet sources. I am not even into university or college yet

rest of 20% is just still unknown for me

[rotund pond]

I did too, but we didn't learn from looking tutos or videos (or maybe 5/10%, not much)
Searching on the net is a powerful tool that somes ignore

[mortal hare]

Im wondering if I should use composition for NMS classes or do inheritance and implement NMS things as a subclass for the base class

and then use a Builder design pattern to build it without client using NMS class level constructors

both approaches seem logical

[rotund pond]

The second one sounds easier to maintain to me, especially if you need to handle a lot of versions 🤔

[hushed spindle]

i just realized that getting a living entity's eye location doesn't work properly when they're riding another entity

their eye location will be where they would be if they werent riding said entity

is there any workaround to where i can get the true eye location of a riding entity

[mighty pier]

is it possible to get entities when theyre unloaded?

[old sail]

How can I open a toolbox without opening any inventory?

[buoyant viper]

assuming getting an entities Y returns the correct pos, u could try entity Y + getEyeHeight

[hushed spindle]

what do you mean toolbox without opening inventory

[agile anvil]

Have a custom resource pack with custom chars. Then manage to align everything

[tardy delta]

But how does that box show up?

[hushed spindle]

what does toolbox mean here

do you mean just a custom gui

in which case yeah the custom char solution will work

[tardy delta]

The Oriental bench thing ^^

[agile anvil]

It's custom chars put in the action bar or in title

[hushed spindle]

i know but i still dont understand what hes asking

[agile anvil]

He's asking how to do it

[tardy delta]

How to show that thing i guess

[hushed spindle]

oh you mean the little indicator, yeah an action bar or title custom char will work

one character for the whole outline, and offset characters to bring the regular text into position

[agile anvil]

N.B: you have to be in 1.13+ (or 1.16+ i don't remeber)

[hushed spindle]

1.13 i believe works

if you want this indicator to be positioned relative to where you're looking at the block you'll have to do some complex math magic to get it to look nicely i think, thats probably possible, but i dont do enough mathamfetamine to know how to

[agile anvil]

I won't say complex ^^ It's just an offset so basically an addition

[tardy delta]

what do they mean with red-black?

[tardy delta]

uh oh i dont know any of that

[echo basalt]

it just means that it won't get too nested apparently

[tardy delta]

hmm ye

[keen star]

Hi

[echo basalt]

load balancing type of thing

[keen star]

i want to get distance between 2 location but i found in bukkit have Distance and Distance squared

[echo basalt]

distance returns the distance

distanceSquared is slightly faster, but returns distance*distance

[keen star]

oh

[echo basalt]

only difference is that distance(Location) calls sqrt(distanceSquared)

[keen star]

oh ok thank you so much

[tardy delta]

¯_(ツ)_/¯

[hushed spindle]

yeah you dont wanna call distance too much

[tardy delta]

any chance that someone wrote a valuesorted treemap impl lol

rewriting the whole thing myself scares me

[subtle folio]

I have a linked map one 😦

[tardy delta]

i guess thats not what i want

i mean wtf

[subtle folio]

yep nope

[golden turret]

is there a way to simulate the EntityDamageByEntityEvent to get the final damage?

[heavy marsh]

Anyone know what could be causing the client to throw a FAILED_DOWNLOAD status when the sha1 changes in the #setResourcePack method?

But then when they rejoin it downloads and loads fine?

[quiet ice]

It's not really possible

That is as long as the value is mutable

If the value is not mutable, then it is possible

[sterile token]

Mutable is that can be changed right?

[tardy delta]

yes

uh oh pain

[sterile token]

And why do you need that fourten?

[quiet ice]

Though at that point I prefer having something like TreeSet<Map.Entry<Key, Value>> with a custom comparator

[sterile token]

What do you want to do fourteek?

[quiet ice]

Probably leaderboard-like functionality

[sterile token]

Hmn

[quiet ice]

It's been far too often that I have needed something like this but I always came back to the TreeSet<Map.Entry>

[sterile token]

Is it a table for displaying player status?

[tardy delta]

uhh well uhh i was thinking about performance
so im currently having a HashMap<K, RemoveQuery<K>> where record RemoveQuery<K>(Consumer<K>, Instant) and i wanted to sort those entries based on the time of the instant

so when i want to execute all the queries in the map which instant is now in the past, i could just iterate thro it and break when those instants arent longer in the past

instead of looping thro a whole map

i guess it works with a normal map too but i was just thinking

[quiet ice]

How large is the map and how much retrieval needs to be done?

[river oracle]

Is your resource pack in a nested folder

[tardy delta]

its basically used as some internal stuff in a usermap so in my server that map wouldnt be large

but ye

[heavy marsh]

nope

[tardy delta]

retrieval is done like every five minutes with a runnable

[river oracle]

So when you open the zip you don't have to open another folder to get to the contents

[river oracle]

Invalid McMeta bad download link are the other two that come to mind

Looping or something else?

[heavy marsh]

download link works, I just used it

here is the generated mcmeta: {"pack":{"pack_format":9,"description":"Backpacks+Netherite Shield"}}

[quiet ice]

And how often do you expect to insert something to the map?

Right now it really seems like a TreeSet<Map.Entry> linked with a regular HashMap should suffice

[tardy delta]

this is the code
https://paste.md-5.net/qemozemero.java
and ye its looping thro it every five minutes
and in the stuff im currently using it for, it inserts an entry whenever an user joins the server

[river oracle]

I'm not an expert on packs I'd look at mojangs documents regarding the pack.mcmeta and creating valid packs

[dire marsh]

@heavy marsh check your .minecraft/latest.log

[heavy marsh]

I am not sure what the problem is tbh since the pack does work, but not on the first join, you rejoin and it loads fine

[quiet ice]

I would use a Deque

[tardy delta]

a deque is only <E> right, so no keys values?

[heavy marsh]

[tardy delta]

yep but i need keys values to be able to run the consumer

[dire marsh]

what's the line above it

[hybrid spoke]

just use a list of entries and sort it by the value

then put it into your map

[quiet ice]

I'll see if I can improve the performance and open up a PR if needed

[tardy delta]

whats a pr

[heavy marsh]

a pull request

[dire marsh]

well it's the wrong sha-1 hash

[hybrid spoke]

public relation

[tardy delta]

thats what google showed me smh

[dire marsh]

whatever hash you're telling the client it should be, the client is not receiving the same from the download

[quiet ice]

I can also mail in a regular git patch if needed

Doing it the good ol' way

[heavy marsh]

yes I know, because the resourcepack content has changed

[dire marsh]

yes

[heavy marsh]

should the hash be static?

[dire marsh]

no

[heavy marsh]

🤔

[river oracle]

Delete your server pack cache in .minecraft it should resolve your issues

[dire marsh]

what have you set the hash to

[tardy delta]

uhhh ok ig

[river oracle]

If it's incompatible hashes could be an issue with a cache

[quiet ice]

It would take too much time to explain my idea to you, you'll get what I mean when I'm done - sorry

[tardy delta]

👀

[heavy marsh]

What I am trying to solve is how to have the resource pack load when the client joins and the contents of the resoucepack have changed. Since currently the client joins, fails to load the pack since the hash is different, but then doesn't load the new pack?

[dire marsh]

what are you setting the hash to

and the url

[heavy marsh]

one sent by my server that handles resource packs, here is the code:

String resources = ResourceManager.getResources();
String packUrl = "http://ADDRESS/spigot-resource-combine?resources=" + resources;

byte[] sha1 = null;
try {
    URL url = new URL(packUrl + "&sha1=true");
    HttpURLConnection connection = (HttpURLConnection)url.openConnection();
    connection.setRequestMethod("GET");

    int status = connection.getResponseCode();
    if (status < 300) {
        BufferedReader receive = new BufferedReader(new InputStreamReader(connection.getInputStream()));
        String base64 = receive.readLine();
        receive.close();
        sha1 = Base64Coder.decode(base64);
    }
    connection.disconnect();
} catch (Exception err) {
    err.printStackTrace();
}
player.setResourcePack(packUrl, sha1, true);

[dire marsh]

well that complicates things

[heavy marsh]

I have confirmed through logging that the sha1 is received and properly decoded and is equal to the one on the web server

[bold solstice]

Can someone help me understand why it sends me this error in the console multiple times when I try to damage an entity for example
Could not pass event EntityDamageByEntityEvent to Races v1.0.0
org.bukkit.event.EventException: null

[dire marsh]

Have you tried manually downloading the zip and checking the hash yourself?

[heavy marsh]

yep

they match equally (to the one generated on the server)

[heavy marsh]

it just seems that the client is unhappy with the hash changing

[dire marsh]

and the hash is 622002d125fd3089142504df7b618526f6e3f8bf?

[heavy marsh]

yep

wait

no it is e8d528156403330d396ed70acf24b8327ce05f37

[golden turret]

is there a way to simulate the EntityDamageByEntityEvent to get the final damage?

[heavy marsh]

that is the old hash

[dire marsh]

according to the client, you're sending it 622002d125fd3089142504df7b618526f6e3f8bf whilst it's expecting what you said is the current hash e8d528156403330d396ed70acf24b8327ce05f37

[heavy marsh]

expected 622002d125fd3089142504df7b618526f6e3f8bf, found e8d528156403330d396ed70acf24b8327ce05f37?

[dire marsh]

yes

[heavy marsh]

well of course because the pack has changed

feels like we are going round in circles a little bit 😅

[dire marsh]

🤔

the found part is the file hash that it downloaded

the expected is what you sent it

[heavy marsh]

hmm

[dire marsh]

what if you delete your server-resource-packs folder like ysk said?

[heavy marsh]

then it downloads fine

it just doesn't initially work if a client has an old version of the pack (aka the sha1 changes)

[dire marsh]

what's your client version?

[heavy marsh]

1.19

[river oracle]

I've never had this issue when changing packs in the past

What fork are you on

[dire marsh]

and applying it works the 2nd time?

[heavy marsh]

and not passing a sha1 is obviously problematic since the client will not download the new version

[clever musk]

Can NamespacedKeys have dots? like a maven artifact

[heavy marsh]

yep

[dire marsh]

you could be right that it's a bug then

i've never been able to reproduce it myself but other people have mentioned it here https://bugs.mojang.com/browse/MC-164316

"I am having a similar issue, but it is not failing to delete the file, it just fails to apply the new pack. This seems to be new 1.17 behavior:"

[river oracle]

Hmmm MC bug hopefully they fix thag with 1.19.1 release

[heavy marsh]

probably not

[subtle folio]

1.19 chat bans

[river oracle]

Never know

[dire marsh]

it's been open since 2019 and is low priority

[river oracle]

That's an oof

[heavy marsh]

here is my janky solution for now then 😕

@EventHandler
public void onResourcePackStatus(PlayerResourcePackStatusEvent event) {
    Player player = event.getPlayer();
    if (event.getStatus().equals(PlayerResourcePackStatusEvent.Status.FAILED_DOWNLOAD)) {
        player.kickPlayer("Server resource pack has changed or resource pack failed to download.\nPlease rejoin.");
    }
}

[dire marsh]

you can try changing the url

as that will make it work

[heavy marsh]

that seems like a pain, unless I send the sha1 in the url?

[dire marsh]

Yeah

[heavy marsh]

ok let me try that

[subtle folio]

===

[dire marsh]

at least according to the bug report that should work

[heavy marsh]

give me like 15 minutes, gotta change the web server behaviour

[ivory sleet]

Myes… I haven’t coded that much lately

Mostly cause I was learning Rust :>

[tardy delta]

owo

[quiet ice]

Having a LinkedList that is only iterated partially is far more optimal than having a HashMap that has to be fully iterated upon or even sorted

[quaint mantle]

If the setting is set, how to get it?

[tardy delta]

hmm i understand what youre doing

[tepid thicket]

https://i.ibb.co/HXMD5HR/image.png

Reading blocks from unloaded chunks causes a massive lagspike.

Is there a way to perform the loading async and then react sync to the result?

[quiet ice]

You might even be okay with just having two collections, an DelayQueue and a Map but that system would be a lot more finicky to implement

[ivory sleet]

Yea

[tepid thicket]

How?

[ivory sleet]

Perform the task on another thread and then subsequently take the result and consume it with BukkitScheduler::runTask

(I assume by sync you mean server thread)

[tepid thicket]

So it is safe to load chunks from another thread?

[tardy delta]

dunno what a delayqueue is

[quiet ice]

Basically something that does what you want, but just for adding and not for removal iirc

[tardy delta]

hmm i seem to understand the principle

[ivory sleet]

Well you have chunk snapshot

[tardy delta]

An unbounded blocking queue of Delayed elements, in which an element can only be taken when its delay has expired.

[ivory sleet]

But iirc doesn’t have anything regarding loading chunks

[tepid thicket]

I want to get the chunk object to read the block states.

[ivory sleet]

Yeah

ChunkSnapshots are capable of doing that async iirc

Idk how up-to-date they are due to thread safety

But up-to-date enough unless you do stuff atomically etc

[tardy delta]

im bored anyways 😂

[quiet ice]

It is likely going to be less efficent anyways

DelayQueue is concurrent, which you seem not to care about

[tepid thicket]

A ChunkSnapshot seems to be able only capable of proving materials, not block states.

I'm looking for something like world#getChunkAt() but in an async fassion.

As I think, it's not safe to call this method from another thread, right?

[ivory sleet]

Oh yeah you’re right

[snow compass]

I´m confused abut this error https://pastebin.com/LmzLeV9M I know the error, but not way it print error. Look more like the method spigot/bukkit use ignore the if check I have and try load every class in the method i have.

[ivory sleet]

I would presume and say it’s not safe

Might even be caught

[tardy delta]

hmm true

[eternal oxide]

Does this happen on Spigot too?

[snow compass]

should not mater, but yeah I can look on spigot also

[subtle folio]

https://paste.md-5.net/tuyeqijusi.md I have a jar in my plugins files, but It wont build with it for some reason?

added it as a depencicy in project strucutre aswell

[eternal oxide]

you are building with maven. If maven doesn;t know about that jar it will not include it

[lost matrix]

Why do you have a jar in your plugins files???

[lost matrix]

Btw do you build artifacts? Or how do you compile?

[subtle folio]

[subtle folio]

does it need a repo?

[eternal oxide]

no

[subtle folio]

just a dependcy

ok

blood eko what are you doing

[tepid thicket]

Sorry, misstyped. Hold on.

[subtle folio]

editing exists ..

[tepid thicket]

Yeah. As in the new version the loading time became way worse. Minecraft even parks the loading call sync.

Eventually this would be up then to a feature request. As Paper seems to have a getChunkAtAsync() method.

Alright thanks guys.

[tardy delta]

CompletableFuture.supplyAsync(getChunkSync) kekw

[tepid thicket]

No, I think calling getChunk() async is still not safe.

[lost matrix]

Thtats what the "kekw" was for

[tardy delta]

doing your mom async isnt safe too

smh

[lost matrix]

I mean you can call it async. Just not from a different thread.

[tardy delta]

doesnt async mean another thread?

away from some main thread

[eternal oxide]

not always

[lost matrix]

Nope async just means out of sync. So if you want to request 100 chunks and do 10 chunks each tick for 10 ticks
then you computed this workload async.

[tardy delta]

aaah

[quiet ice]

For me async just means "not now"

[lost matrix]

First mistake im seeing:
Never compare objects with == unless you want to check for identity (exact memory address)
For primitives and enums its good but you dont want to use this for Objects like Strings.
So someString == "" will always be false.

[hybrid spoke]

it will load the chunk

if its unloaded

and you cant load the chunk async

[lost matrix]

Next mistake: You are using something else than the PDC to check for custom or tagged items.
You should always use the PDC to tag an ItemStack. Never use the name, lore or other properties.

  public void toggleLock(ItemStack itemStack) {

    PersistentDataContainer container = meta.getPersistentDataContainer();

}

[gritty urchin]

hey

how do I update a GUI Inventory's items

without closing it

tried Player#getInventory

but that gets their own inventory not the chest/gui inventory

[lost matrix]

A gui is just an inventory. You can place ItemStacks in there whenever you feel like it.

[snow compass]

on spigot https://pastebin.com/y2hhqLaK

[gritty urchin]

yes I know

but it does not update for the player

when I change it

[paper falcon]

How would I make an ItemStack have limited uses? E.g. I'm making a lightning Blaze rod and want to put 100 uses max.
The lore would also update itself with the uses left.

[gritty urchin]

register each use per player

[eternal oxide]

It looks like a serialization error. are you saving/loading Particles to a config?

[gritty urchin]

and when it reaches the maximum

remove from their inventory

e.g. playerinteractevent

check for the specific item

add player to a hashmap with player and uses

[snow compass]

Way I´m confused is I checking the server version and it still try load things I stop the java to read. I know the if checks works but seams it read whole class and ignoring my limit I set .

[gritty urchin]

and deduct each time

[lost matrix]

Use the persistent data container to store data like uses.
Then on interact you update the ItemStack.

[lost matrix]

This is dirty but it sounded like what you wanted.

    Player player = ...;
    Inventory guiInv = player.getOpenInventory().getTopInventory();
    guiInv.setItem(10, ...);
    player.updateInventory();

[gritty urchin]

ah thanks

this is what I was looking for

Inventory guiInv = player.getOpenInventory().getTopInventory()

[paper falcon]

Haven't worked with PDC yet so I think it will be a nice practice, thansk

[charred blaze]

itemmeta.setdisplayname("s");

maybe?

[lost matrix]

This is expected behavior. If you rename an ItemStack like that in minecraft then it becomes cursive. You need to specify a styling to change the appearance.

[eternal oxide]

If you are using Components in naming you are not using Spigot

[heavy marsh]

As 7smile7 said: #setDisplayName(ChatColor.RESET + name) or the component equivalent should work

[charred blaze]

most of times im ignoring deprecated things... just use it

thats same but with chatcolor

[lost matrix]

    ItemStack itemStack = new ItemStack(Material.IRON_AXE);
    ItemMeta meta = itemStack.getItemMeta();
    meta.displayName(Component.text("Mithril Axe").color(NamedTextColor.AQUA));
    itemStack.setItemMeta(meta);

This also works

meta.displayName(Component.text("§eMithril Axe"));

Or RGB:

meta.displayName(Component.text("§eMithril Axe").color(TextColor.color(240, 200, 90)));

[snow compass]

The class some is the problem https://pastebin.com/PKvKKnjR

[heavy marsh]

what adds that #displayName?

[lost matrix]

Wood based fork

[eternal oxide]

Have you registered this class?

[lost matrix]

Bleached wood for that matter

[heavy marsh]

interesting

[snow compass]

ofc it work fine with out Particle.DustTransition class added.

[eternal oxide]

Thats because DustOptions is not ConfigurationSerializable

[charred blaze]

wasnt are you talking about display name change? xd

[heavy marsh]

Can confirm that sending a different URL with the changed hash will make the client load the resource pack

[snow compass]

is no problem with DustOptions only DustTransition and no I not add that to config (needed to make my own ParticleDustOptions() class for that so that are not the issue).

[eternal oxide]

You have to do the same for DustTransitions

[hidden kestrel]

I'm attempting at a multi-world plugin - I have 2 separate worlds with each of their own nether & end dimensions.

I'm having some issues with the end.

1. I use PlayerPortalEvent#setTo() to teleport to the correct end world. Here I use #getSpawnLocation() of that world. The spawn location of said world appears to also be the spawn location of the fountain. How do I get the correct location where you would normally spawn after entering an end portal?

2. I use the same event for when leaving the end, making sure the player goes to the correct dimension, with the player's respawn point. I checked for the TeleportCause if it was == END_PORTAL, but it appears the fountain is actually an END_GATEWAY, as I ended up in the void upon entering it. How can differentiate the player from entering the fountain's portal, and using an actual gateway with enderpearls?

[eternal oxide]

Because extends Particle.DustOptions

[charred blaze]

does anyone know?

[snow compass]

Yea is how I done it, look inside serialize(). I then convert it back in deserialize. but seams it read deserialize and ignore if statements when bukkit/spigot use reflections.

[clever musk]

Are there plans to make org.bukkit.block.Biome abstract?

[lost matrix]

Advancements have to be known when the player joins. So you should be able to just create a bunch of advancements (in a resourcepack) and
change the description, icon, title and type however you please.

[charred blaze]

resourcepack?

[hidden kestrel]

Related to advancements, is there a way to list the player's advancements??

[charred blaze]

it needs resourcepack?

[somber sequoia]

is there any way to refresh the inventory in the InventoryClickEvent? I need to get what item has been put into the menu

[lost matrix]

Pretty sure biomes are already data driven in nms. So Spigot will follow that sooner or later.

[quiet ice]

Yes, it will be a registry eventually

[ornate heart]

I'm using this to set the player's max health. It's changing the attribute value in the code. I know this because I'm printing out the value right after I change it, but it's not changing my heart amount. Any reason for this?

[quiet ice]

However right now it still stays an enum due to backwards compat

[charred blaze]

cant i change title of it without resourcepack?

[lost matrix]

Did you fix the display for your hearts? Sounds like you pinned it to 10 hearts.

[lost matrix]

Let me check the protocol.

[ornate heart]

What do you mean by fix the display? How would you fix the display?

[lost matrix]

You can specify if the amount of hearts correlate with the players max health.
You can as well just pin it to 10, 20, 30 ... 1 heart.

[ornate heart]

Ok so how would I just have the player have 5 hearts. I thought doing

player.getAttribute(Attribute.GENERIC_MAX_HEALTH).setbaseValue(10);

would do that. Do I have to do something else?

[lost matrix]

setHealthScale(double)
setHealthScaled(boolean)

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/entity/Player.html#getHealthScale()

setHealthScaled(boolean) -> defines if the health should scale automatically

[ornate heart]

Is this new? I didn't even know this was a thing

[lost matrix]

Cant remember if it every wasnt a thing.

[lost matrix]

Actually im seeing some packets that let you update advancements on the fly.
I didnt find any api for this. Let me get ProtocolLib and play around with it a bit.

[charred blaze]

uhh

i think playing with packets is pretty hard

i dont know i can go on this

[lost matrix]

Because you set it to a fixed location. It doesnt follow the player.

[somber sequoia]

any ideas?

[rough drift]

How can I move a location forward based on it's direction?
