[upper hazel]

hey, how is the sorting system in minecraft auction plugins? According to the material, it’s hardly because there are donated items, but they are somehow sorted separately

[abstract sorrel]

does anyone know how i would achieve something like this:

file = new ConfigFile("playerdata/world1", player.getUniqueID().toString())

Where it would create the folder path inside the default plugin folder and create a file inside named the player's id?

[river oracle]

does Command#register actually register the command to the command map I see no indication it does

its so weird

[quaint mantle]

Reflection call syncCommands method

Server class

[tender shard]

no. commands are registered in SimplePluginManager -> enablePlugin(Plugin). this gets a list of all commands of that plugins and then calls SimpleCommandMap.registerAll(...) on it, which just calls SimpleCommandMap.register(...)

i have no clue what Command#register is used for

[young knoll]

I think there was a brief discussion on exposing the register method

Since so many people use it anyway

[river oracle]

https://hub.spigotmc.org/stash/projects/SPIGOT/repos/bukkit/pull-requests/542/overview

I use it lol

fuck using the plugin.yml

[silver robin]

I wanted to give an answer to my own question here
the problem was in the line where i set nametag visibility of ScoreboardTeam, it happened to send the update to every player
the way i found out is by printing the stack trace in the packet listener
anyway, peace

[young knoll]

Ah yes that one

[river oracle]

What's a nice way to loop over a map and remove stuff without getting ConcurrentModificationExceptions

[young knoll]

Iterator

[river oracle]

alr

[tender shard]

or just simply removeIf

[young knoll]

True

[river oracle]

fuck I forgot about that

oh map doesn't have removeIf though

[eternal oxide]

it does

entrySet

[river oracle]

oh does the entry set modify the map itself

[eternal oxide]

yes

[river oracle]

ahhh makes sense

[tender shard]

        // Iterator
        Iterator<Map.Entry<Object,Object>> iterator = map.entrySet().iterator();
        while(iterator.hasNext()) {
            Map.Entry<Object,Object> entry = iterator.next();
            iterator.remove();
        }

        // removeIf
        map.entrySet().removeIf(entry -> entry.getKey().equals(entry.getValue()));

        // Second collection
        Collection<Object> keysToRemove = new ArrayList<>();
        for(Map.Entry<Object,Object> entry : map.entrySet()) {
            keysToRemove.add(entry.getKey());
        }
        map.keySet().removeAll(keysToRemove);

these are the first 3 methods that came to my mind, there's probably at least 5 more ways lol

[desert loom]

pretty sure keySet() and values() reflect changes too

so you can also use those with removeIf/iterator

[shadow night]

Is there a way to register a command during the runtime? Maybe by like modifying the tab completion event and the command handle event or whatever to make a custom command handling thing?

[tender shard]

just add it to the command map

[river oracle]

yeah I'm working on that rn

its really easy

[young knoll]

Dang we were just talking about this

:p

[shadow night]

That shit exists?

[young knoll]

Yes

It’s just not exposed

[river oracle]

this is what I do

    public static void register(@NotNull final Plugin plugin, @NotNull final Command command) {
        final CommandLabel label = command.commandLabel();
        final PluginCommand pluginCommand = ReflectionUtils.newInstance(PluginCommand.class, new Object[]{label.name(), plugin});
        if (pluginCommand == null) {
            throw new RuntimeException("Creation of PluginCommand failed");
        }
        pluginCommand.setName(label.name());
        pluginCommand.setAliases(label.aliases());
        pluginCommand.setPermission(label.permission());
        pluginCommand.setUsage("/" + label.name());
        pluginCommand.setExecutor((s, c, l, a) -> command.execute(s, a));
        pluginCommand.setTabCompleter((s, c, l, a) -> command.complete(s, a));

        if (commandMap == null) {
            init();
        }

        if (!commandMap.register(plugin.getName(), pluginCommand)) {
            throw new IllegalStateException("Command with the name " + pluginCommand.getName() + " already exists");
        }
    }```

[shadow night]

Wow

[tender shard]

cast PluginManager to SimplePluginManager, get commandMap with reflection, done

[shadow night]

Just make it a lib or something

[cinder abyss]

Hello, how can I make a ServerPlayer (fake) join the server (I want to get the join message) in 1.20.1 with nms ?

[shadow night]

Maybe call the PlayerJoinEvent? Idk never made fake players

[cinder abyss]

with nms

[tender shard]

https://github.com/JEFF-Media-GbR/JeffLib/blob/master/core/src/main/java/com/jeff_media/jefflib/CommandUtils.java#L81C47-L81C47 to get the commandmap

[river oracle]

commandMap = ReflectionUtils.getField(Bukkit.getPluginManager(), "commandMap", CommandMap.class); one liner with reflection utils

[shadow night]

Well, I never knew you can without nms

[eternal oxide]

I've never seen it done as it's a completely different set of packets

I lie

[tender shard]

I sit

[river oracle]

I jump

[cinder abyss]

[eternal oxide]

Magma somethign was playing with it a few months back

[cinder abyss]

Well, maybe this ? But idk how to use it : https://mappings.cephx.dev/1.20.1/net/minecraft/network/protocol/game/ClientboundLoginPacket.html

[shadow night]

PlaceRecipePacket

[cinder abyss]

well

[shadow night]

I will never get packets tbf

[cinder abyss]

wrong link

[river oracle]

How should I check if two plugins are the same can you compare plugin with .equals?

[quaint mantle]

hi guys can i do bungeecord api ?
i mean i will api in bungeecord server and other servers will get data from this api

[cinder abyss]

(updated)

[shadow night]

Can't you like use the name or something?

[river oracle]

i thought you could have 2 plugins with the same name

[eternal oxide]

@torn shuttle Tell us of your wizardry in logging a fake player in.

[shadow night]

the name is kinda like an id afaik

Like, your plugin is identified by the name in your plugin.yml, usually

Bedrock plugins have an UUID system

[river oracle]

lord this looks horrible

        knownCommands.entrySet().removeIf((Map.Entry<String, org.bukkit.command.Command> entry) -> {
            final String label = entry.getKey();
            if (!(entry.getValue() instanceof PluginCommand pluginCommand)) {
                return false;
            }

            return plugin.getName().equals(pluginCommand.getPlugin().getName());
        });

[tender shard]

no

[river oracle]

bedrock is just bad though so who cares

[shadow night]

So, is the name like an identificator?

[cinder abyss]

thanks to his chat history, I found something that can also help me for another project 😄 https://github.com/MagmaGuy/FreeMinecraftModels

[tender shard]

if you have two plugins with the same name, this happens

[19:53:20] [Server thread/ERROR]: Ambiguous plugin name `Daytime' for files `plugins\Daytime-1.0.0.jar' and `plugins\Daytime-1.0.0 - Kopie.jar' in `plugins'

and then it only uses one of those

[shadow night]

Well, can't say it isn't, but I like both versions of the game, even for modding. Like, have you seen the inner-core? Broo that's soo cool.

[young knoll]

Can you not just fire a fake login event and then send the resulting message to everyone

Isn’t that basically all login is

[cinder abyss]

how ? 😅

[young knoll]

Idk what does a login event require

Player and join message?

[quaint mantle]

can i make api plugin ?...

• but this api plugin will be in bungeecord.
• and it will transfer data to the plugin inside a non bungeecord server

[cinder abyss]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/event/player/PlayerJoinEvent.html

something interesting

[river oracle]

When you do reflection on a field that is a collection is the field updated as things are appended to the collection

[cinder abyss]

if it works, nothing to do with nms

[river oracle]

I would assume yes I just feel like so scared it doesn't

[cinder abyss]

@young knoll I can really make an instance of a Event ?

[onyx fjord]

https://www.spigotmc.org/wiki/bukkit-bungee-plugin-messaging-channel/

[tender shard]

ofc not, the field stays the same

the field is just like a "pointer" to your collection

[young knoll]

Yes

[tender shard]

you can change the collection all you want, doesn't have anything to do with the field object

[young knoll]

Granted the event will only handle the join message

You still have to send the NPC to all the clients

[tender shard]

sure but it's not really allowed

[cinder abyss]

idk what to put in String joinMessage

[young knoll]

The join message

[tender shard]

well how aobut "mfnalex joined the game"

lol

[cinder abyss]

I want the default joinMessage or the join message set by a plugin

[young knoll]

I believe the default is just “X joined the game” in yellow

Yes plugins can then modify it when you call the event

[cinder abyss]

I can just put the default one and the plugin modify it laters normally

Event instantiation trigger the EventHandler ?

[tender shard]

no

you call PluginManager#callEvent

[cinder abyss]

so that's what I need to do

[river oracle]

so every time I run my method I'll have to update the reflected field value

that fucking sucks

[tender shard]

no

why would you

[river oracle]

idk I thought you said it didn't update

[tender shard]

I said the field object doesn't change

which is what you want

you want it to still point to the collection you got earlier

[cinder abyss]

main.getServer().getPluginManager().callEvent(new PlayerJoinEvent(craftPlayer.getPlayer(), "Herobrine joined the game"));```

[tender shard]

just because you're using reflection to get a field's value doesn't magically produce a clone of that value

[tender shard]

yeah but you're not really supposed to do this

[river oracle]

I'll explain better ig

private static List<String> reflectedList;

static {
  reflectedList = magicReflectedField.get(null);
}

so this would be synced up?

[echo basalt]

Yes

It's returnin the same object and not a copy of it

[tender shard]

I really don't know what you mean with "synced up"

[river oracle]

alr thanks

[echo basalt]

It's no different than calling a getter

[river oracle]

the pointers point to the same memory location

[echo basalt]

but if the reflected list is reassigned then it desyncs

[tender shard]

myList = OtherClass.myList;
myList = OtherClass.class.getDeclaredField("myList").get(null);
// the same

[cinder abyss]

I understood nothing 😢

[austere cove]

since the field is not final, if a new value gets assigned the reflected value needs to be manually updated too

[river oracle]

well if its in NMS its not a huge deal tbh, because you're updating every version anyways

[sterile breach]

Hello, inventory.getsize return the max slot or rows?

[echo basalt]

slot

[river oracle]

considering the field is final I'm working with doubt I'll need to worry about that then

[sterile breach]

thanks

[tender shard]

Getting a fields value through reflection is exactly like as if you‘d get it directly

[tender shard]

^

[austere cove]

in that case the value obtained from reflection and the field value are the same (i.e. ==)

[river oracle]

yeah idk why, I was just really worried that they wouldn't point towards the same memory location for some reason

[tender shard]

Think of the field as if it was a pointer

Kinda

[austere cove]

mutability and concurrency are headaches. I love rust

[tender shard]

Rust mc server when

That implements spigot api

[young knoll]

What does rust not let anything be mutable

Kek

[lilac dagger]

Wait actually?

Why?

[austere cove]

no but its safe so that it cant be modified concurrently by design

[young knoll]

Just use locks smh

Or synchronized

[lilac dagger]

What happens if you add an element in a collectiom in rust?

[proper notch]

Valence

[lilac dagger]

Are they all copyonwrite?

[hazy parrot]

That would make no sense lol

[river oracle]

I'd assume it depends how you define it, that'd be slow

[quaint mantle]

hey, how do I block creeper block damage without changing the overall explosion radius?

is there an event for this?

[river oracle]

rust is memory safe first and fast second, so I doubt they'd copy on write every single append

[hazy parrot]

I mean I don't know rust, but I doubt every list is copyonwrite

[river oracle]

?jd-s

[undone axle]

https://hub.spigotmc.org/javadocs/spigot

[river oracle]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/entity/EntityExplodeEvent.html

remove from the blockList

[young knoll]

^ it’s mutable

You can just clear it if you want no blocks broken

[quaint mantle]

oh thanks. because I had the problem, I changed explosion radius to 0 but then I noticed player damage is also blocked which I dont want

[river oracle]

real question are you even using paper API if this isn't at the top of your class?

[young knoll]

That’s why I’m simply not using paper api

[tender shard]

same

[cinder abyss]

Well, it isn't working...java main.getServer().getPluginManager().callEvent(new PlayerJoinEvent(craftPlayer.getPlayer(), ChatColor.YELLOW + "Herobrine joined the game"));@tender shard

it does nothing

[young knoll]

You need to take the result of the event and send it to all players

Well, the result message

[austere cove]

what are you trying to do

[cinder abyss]

oh okay thanks

[cinder abyss]

fake join message

[young knoll]

You can technically just skip the event and send the message

[quaint mantle]

someone know mysql ?
i got this error on exporting

[young knoll]

But then other plugins won’t be able to change it

[cinder abyss]

soooo ?java Bukkit.broadcastMessage(new PlayerJoinEvent(craftPlayer.getPlayer(), ChatColor.YELLOW + "Herobrine joined the game").getJoinMessage());

[young knoll]

You still need to call the event

[cinder abyss]

okay

[austere cove]

PlayerJoinEvent event = null;
Bukkit.getPluginManager().callEvent(event);
String message = event.getJoinMessage();
if (message != null) {
    Bukkit.broadcastMessage(message);
}

[cinder abyss]

and get the result inside ?

[austere cove]

(except don't use null obviously)

[young knoll]

^

[cinder abyss]

okay thanks

[tender shard]

ofc it does something, it calls all EventHandler methods that listen to PlayerJoinEvent

[cinder abyss]

I thought it was sending the message, but no

[young knoll]

Nah event calls are never responsible for actually performing the event

That comes after

[cinder abyss]

perfect thanks 😄

[quaint mantle]

yes i do

(sorry for necroposting)

How to code a PacketReader in a version higher than 1.19.4?

Does anyone have a ready class they would like to share

[quaint mantle]

Hi , how to connect to mysql in easy way and short code ?

[austere cove]

DriverManager#getConnection(String)

[austere cove]

inject a handler in the connection pipeline

[terse bough]

I know but how do I get this pipepline from a player since the 1.19.4 changed something

[quaint mantle]

and connect a event ?

i mean a connection event for mysql

[dawn plover]

why is everything givingan error for some reason, i littaraly build it a minut ago without even opening this file. so the code is correct

bruh this makes my brain hurt
it littaraly build succesfull with all these errors

[worldly ingot]

Most likely just an IDE cache issue or something

[dawn plover]

thats the .idea folder right

[terse bough]

Guys, how do I get this pipeline from a player since the 1.19.4 changed something

[young knoll]

pipeline?

[sterile breach]

Hello, in the inventory object, if i open the same inventory for two players, thes two inventory are considered like equals?

[young knoll]

Yes the inventories will be equal

But the views will not be

[dawn plover]

its like 2 players look inside the same chest, if one picks an item, its also gone for the other

[terse bough]

to inject an packetreader yk

[lilac dagger]

packet listener?

[sterile breach]

not really, i use the "modearn aproche for gui(exemple)" so its create 2 separate inventories i aimgine?

[worldly ingot]

I use Eclipse ¯_(ツ)_/¯

[dawn plover]

?, i have no idea what the "modern aproche" is, but an inventory is an invetentory. they are shared objects just like in vanilla
so that "modern aproche" then probably makes a new instance for eveyone or something

i just use the default inventory object, and if i make any changes, it will change for everyone

[sterile breach]

https://www.spigotmc.org/threads/a-modern-approach-to-inventory-guis.594005/

we have a manager (hashmap) inventory, menuclass

so , on action, the manager get the eventinventory and got menuclass in hashmap.

My question, if 2 players open the same inventory, in the hashmap, there will be a difference between the 2 inventory keys?

[quaint mantle]

What can I use instead of ChatColor, because it is deprecated? is there an easy method?

[young knoll]

It's not

Ur using the paper api

[river oracle]

paper user spotted

[young knoll]

Can we get a ?paperapi command

[river oracle]

?fork

[undone axle]

SpigotMC maintains the Spigot server. If you are using a fork of Spigot (such as Paper, Airplane, Purpur, or other derivative works), you should seek support in the appropriate Discord servers.

[dawn plover]

inventory key?!?

[worldly ingot]

If anything it's a dead giveaway now

[vast ledge]

If tree has been setup to torcher user, let me know when we should start

torture**

[sterile breach]

key of hashmap is inventory (instance)

[dawn plover]

(btw that thread is way to long so i am not reading that, also Cntr+f searching for "inventory key" gives nothing lol)
but its really simple
if you have a method simular to openInventory(...) and it creates a new instance of a inventroy every time, then yes, its a seperate inventory, and people wont see any changes appart from themselves
if instead you constantly open the same instance (created once, and then constantly reffered) then and people will see every change you make to it

because you are using hashmap i dont think its even posible to make the first senerio
so key X will always reffer to inventory X, and verse visa
(its because you made the inventory instance once, and saved it at the key. thatway the key has only 1, and always that same 1 instance)

[lost matrix]

If both open the same instance then there is no difference. They both retrieve the same handler from the map.

[river oracle]

How do I decide whether I should use a registry or enum

[quaint mantle]

idk I only use registries when I have like a item registry and a bunch of classes that extend item or smth and then use enum when its like Permission.XYZ

[eternal oxide]

registry if you have a LOT of entries or you need to be able to add/remove entries on the fly

[river oracle]

👍

[sterile breach]

oh so don't worry about that

[quaint mantle]

PaperAPI? More like ComponentAPI

[green plaza]

?

Help please

[quaint mantle]

The exception says literally what the problem is

[grand saffron]

lol

[quaint mantle]

You/your plugin is trying to create a team on a scoreboard, but that team already exists

[green plaza]

So tell me how to fix it

[quaint mantle]

Remove the team (if exists) from the scoreboard then create it

Or modify the existing one

[sweet sonnet]

Is there anyway to not show the users inventory at the bottom?

[echo basalt]

n o

[lilac dagger]

resource pack i think

[sweet sonnet]

Thought so

[quaint mantle]

Has anyone here implemented a grafana dashboard to moniter stuff in a spigot plugin before?

if so did u use prometheus or influxdb?

[quaint mantle]

Not even with resource packs, the inventory will still be there

You will need to create a mod or a modified client version (which will be most difficult to do than a mod)

[cinder abyss]

Hello, two questions :
how can I hide ServerPlayer (nms 1.20.1) nametag with spigot or nms ?
Is player PDC persistent after player disconnect ?

[quaint mantle]

Always remember, non server side controlled modifications requires client side modifications

[chrome beacon]

1. Use teams
2. Yes. The P in PDC stands for Persistent

[cinder abyss]

that was to be sure, thanks 😄

for nametag I found this https://www.spigotmc.org/threads/hide-player-nametags-all-time.356450/

[chrome beacon]

I made a plugin that hides player nametags when they're not visible

Like behind a wall for example

It's not that hard to do

[cinder abyss]

perfect

[cinder abyss]

good idea 👍

[quaint mantle]

Is it worth switching over to library loading instead of shading dependencies?

[young knoll]

I mean

It keeps the jar size down

[echo basalt]

apparently someone found my github project through youtube

the fuck

[young knoll]

TIL you can see that

[echo basalt]

I get all the google ones

because if you search skyblock core spigot my result's just below ssb2

[quaint mantle]

hi guys i have a question
i will do stats plugin but this plugin depends api
if i upload this api to bungeecord
my stats plugin will work ?

[hazy parrot]

💀

[quaint mantle]

what in the world

[bitter rune]

Instance a class, is it this? https://www.javatpoint.com/instantiation-in-java#:~:text=Java provides the new keyword to instantiate a class.&text=We can also instantiate the,we defining a reference variable.&text=We observe that when we,or object of that class.

[hazy parrot]

Yes, you make instance of class using new keyword

There are two ways to create instances:
Using the new Keyword
Using Static Factory Method
But tf is this

[bitter rune]

https://media.discordapp.net/attachments/513404018836504579/1133525467887046767/IMG-20230725-WA0019.jpg

I'll look up new keyword thanks

[hazy parrot]

You can't make new instance of your main class

You have to pass it, either using Di or static getter

?di

[undone axle]

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

[shadow night]

How do you make a static getter?

[bitter rune]

Main class = current class I'm in?

[hazy parrot]

Then just pass this

[bitter rune]

Okay

[hazy parrot]

First argument in runTaskLater should be instance of your main class

[shadow night]

Like, iirc this isn't a thing in static

[hazy parrot]

There is JavaPlugin.getPlugin(Class)

[shadow night]

Ohh that's what copilot suggested me

[hazy parrot]

So you can get instance of your class with getPlugin(YourClass.class)

[shadow night]

That's interesting

[green plaza]

Anyone know how to fix this error and can provide some simple solution?

[cinder abyss]

you create a team two times

(it is already created)

[green plaza]

How can i avoid that? Can you provide me some code that solve it?

[bitter rune]

Thanks, appreciated

[green plaza]

And where should i put that? Because the error occur only in BungeeCord

[cinder abyss]

just check if the team already exist

using Bukkit.getScoreboardManager().getMainScoreboard().getTeam("YOUR_TEAM_NAME");

[green plaza]

Can you show me how? I am fightning with this using SwiftBoard api tried several method and i start doubt my skill

[cinder abyss]

I don't know the SwiftBoard api and I don't know how to use BungeeCord

the only thing I can say to help is #help-development message

[green plaza]

Thats what i am asking for

[cinder abyss]

perfect

[worldly ingot]

Come on, man. Use at least a little bit of critical thinking ;p

The error says in plain English why it's being thrown. So you need to find some way to check if a team already exists on a scoreboard before you register it

Look at the Javadocs or use your IDE to see if there's any method whatsoever that might possibly give you some indication of whether or not a team exists

In this case PauLem is correct, getTeam()'s nullability will tell you if a team exists. But in the future, at least pretend to have put in a little bit of effort

[cinder abyss]

first result for "check team exist bungeecord" on google @green plaza https://www.spigotmc.org/threads/bungeecord-and-scoreboard-packets-illegalargumentex-team-already-exists-error.186994/

same answer

[worldly ingot]

Or, yeah, some simple Google-fu

[twin venture]

what event is triggered when i use a lava bucket?
it will turn it into a bucket??

[worldly ingot]

BucketEmptyEvent

D: What's with the "I don't want to use Javadocs" people today?

[twin venture]

that's not a real thing is it xd?

[worldly ingot]

Yes!

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/player/PlayerBucketEmptyEvent.html

[twin venture]

oh its real event , never heared of it

thanks :p

[worldly ingot]

Javadocs have a search bar, just fyi in the future

[pale hazel]

What is the difference between Enttity and EntityType is an EntityType more specific to an entity type?

[river oracle]

EntityType is just a list of all possible Entities

they don't really have anything in common

?jd-s

[undone axle]

https://hub.spigotmc.org/javadocs/spigot

[river oracle]

Represents a base entity in the world from Entity

[opal juniper]

javadocs are illegal don’t use them

[quaint mantle]

or like YourPlugin.getInstance()

[remote swallow]

public static class getClass

[worldly ingot]

Entity = in world
EntityType = a simple type of entity. Might provide stateless data about a type of entity (e.g. whether or not it's alive, or supported by experimental features, etc.)

How would i create a random number for a minecraft seed?

[wet breach]

Well i think the only limitations for the seed is character limit and alphanumeric

So you could just use a generator from online to make you a seed from those limits

generator from online?

[wet breach]

Yeah there is plenty of web generators to generate random strings with whatever limits you impose

And then you can plug that into the server.properties file for seed. Then delete or move old world and let it make a new one

Server only uses new seed when creating new worlds

[raven fern]

yeah im trying to create new worlds on the fly

just random seed mineecraft survival worlds

cant i just do Math.random() i just dont know what are the restrictions to Minecraft seeds

ig ill just try Math.Random idk

oh that gives a double

[warm light]

I want random float from 0.01 to 100
so what will be the bound?
I am doing new Random().nextFloat(101.0F); rn. but look like its choosing from 10-100

[wet breach]

I will tell you the limits

If you use any alphabet characters or the character limit exceeds 20 characters. The limit is a 32bit int. Negative and positive is allowed. If instead you use only numbers and dont exceed 20 characters the limit is a 64bit long negative or positive

Cant use doubles or floats. Has to be an int or long

[raven fern]

nvm they want to take in a string as the world seed idk how that works but ig i can generate 20 random letters for it

"seedString - The seed in the form of a string. If the seed is a Long, it will be interpreted as such."

[wet breach]

It works by getting the hashcode of the string which gives an int

[wet breach]

This doesnt mean you cant use purely numbers. It is treated as a string because alphabet characters are permitted not just numbers

If the string is nothing but numbers it will treat it as such

[raven fern]

i mean then i can creeatea random string of 20 letters that will bascailyl create a random number

[wet breach]

It should yes

[young knoll]

You can use any long value for the seed

[raven fern]

nah they need a seedstring

[young knoll]

Notice that it says if it’s a long it will be interpreted as such

[raven fern]

so create a random long in the form of a string?

[lost matrix]

You whould just use the random method that resolves a range

    ThreadLocalRandom random = ThreadLocalRandom.current();
    float number = random.nextFloat(0.01F, 100.0F);

[quaint mantle]

anyone know any good inventory api's for 1.18.2+?

[young knoll]

Looks like it

[quaint mantle]

cuz i found a few that imo are pretty good but some how are broken so im still on the hunt

[raven fern]

veri nice

[lost matrix]

Not sure if its still maintained but ive used Triumph a while ago.
But writing your own lib with GUI capabilities is also something you
might want to pursue at some point.

[quaint mantle]

alright thank you!

[raven fern]

long leftLimit = -2147483648;
        long rightLimit = 2147483647L;
        long seed = leftLimit + (long) (Math.random() * (rightLimit - leftLimit));

@young knoll i think i did it right

[young knoll]

Just use ThreadLocalRandom

[lost matrix]

ThreadLocalRandom random = ThreadLocalRandom.current();
long number = random.nextLong();

[young knoll]

^

[raven fern]

ty

[wet breach]

This doesnt really create a range.

There is methods to create a range to input in for picking a random value

[lost matrix]

Was just thinking about that. I would honestly just multiply the random by 2 and multiply with the long max value.
Then overflows will take care of the negatives.

[warm light]

still not getting 0.9 or less
tried 1300 times

it always start from 1

[lost matrix]

  public static void main(String[] args) {
    int belowOne = 0;
    for (int i = 0; i < 1_000_000; i++) {
      float random = randFloat();
      if (random < 0.9F) {
        belowOne++;
      }
    }
    System.out.printf("Generated %d numbers below 0.9%n", belowOne);
  }

  private static float randFloat() {
    ThreadLocalRandom random = ThreadLocalRandom.current();
    return random.nextFloat(0.01F, 100.0F);
  }

Out

Generated 9040 numbers below 0.9

Process finished with exit code 0

9000 is about 0.9% of 1_000_000 so this sums up

[young knoll]

Oh good the laws of math are still working

[wet breach]

So went and had a look and the random method has been updated. Dont know when and it automatically generates randoms in both directions from min negative to max positive if you dont specify a range. Which is what they want so they only need this code you provided lol

Time to keep that info tucked away for later now

I only remember it generating values from 0 to max positive

[spark lynx]

is there any ways to make npc(fake serverplayer) class instanceof Player?

[lost matrix]

Thats a weird question. NPC is an interface which extends Creature iirc.
What are you trying to do?

[spark lynx]

my fake player extends ServerPlayer , but it doesn't instanceof Player

[lost matrix]

It is

Its an instance of net.minecraft.world.entity.player but not org.bukkit.Player

[chrome beacon]

Gotta wrap it with CraftPlayer if you want a bukkit player

[lost matrix]

If you want to check for instanceof for the bukkit player then you need to get the bukkit player from your nms player.
So

if(nmsPlayer.getBukkitEntity() instanceof org.bukkit.Player) {

}

[tender shard]

huh, in which scenario would an NMS player (I assume we are talking about ServerPlayer) would not have a method getBukkitEntity() that does NOT return a bukkit Player?

ok tbh "nmsPlayer" could be anything

[lost matrix]

There is none

Unless the overwrite the getBukkitEntity method

Or yeah, nmsPlayer could be some nmsEntity

[tender shard]

yes and no

[lost matrix]

It wont look like a circle. Even with interpolation you are limited by the clients framerate

[tender shard]

1st: are you fine with a 20FPS spinning cube being considered a circle?

maybe you could show us a video

[lost matrix]

Hm i think a flying ice block that rotates slowly + a few of those particles in the end will look nice

Doesnt need to be a circle

[tender shard]

yes

[lost matrix]

[sterile breach]

hi, when I query the database, do I always have to do it in async?

[lost matrix]

You should never do any IO on the main thread. For example: If you query a database inside a
listener and the database is not reachable then your server just crashes. And IO is very slow.
So in most cases it produces a ton of lag, very quickly.

[lost matrix]

Paint me a picture. What do you want to get from the DB and when?
Ill give you the best approach to this.

[sterile breach]

when a player logs in, I retrieve his info from the db and store it in the cache, then when he leaves or when the server shuts down, I put the data back in the db

[lost matrix]

Use the AsyncPlayerPreLoginEvent to load the data.
You can do IO in this event and the player will see a loading... screen while you load his data.
It prevents the player from joining while you load his data.

When the player quits then you should save the data async.

When the server stops then you should save all data sync.

[chrome beacon]

Also do regular saves from time to time to prevent data loss during crashes

[sterile breach]

these are very small data, is it really necessary for when it connects?

[austere cove]

..yes

[sterile breach]

and just async at login?

[daring schooner]

This looks like Humble Vr in minecraft

Looks fun

[lost matrix]

Depending on where your DB is the connection allone could take upwards of 10ms.
Now imagine 10 players connecting quickly. Then it doesnt matter how small the data is, you will produce lag.
And if the DB is busy or not reachable then your server crashes as well. So its necessary.

[sterile breach]

and you say I can show a loading screen to keep them waiting?

[lost matrix]

And at logout.
But at login you should load the data before the player actually joins and
not in the PlayerJoinEvent

[sterile breach]

asyncPreQuitEvent exist?

[lost matrix]

This would delay a login from each player by 2s without affecting your game.

  @EventHandler
  public void preLogin(AsyncPlayerPreLoginEvent event) {
    Thread.sleep(2000);
  }

It will show the default login screen of the client.
Now replace that sleeping with any IO.

[lost matrix]

Nope. On quitting you need to properly handly the async requests.

[sterile breach]

what do you call io? so everyone would slow down by 2 sec? it's annoying

[lost matrix]

But make sure that your "cache" is thread safe or else you will get ConcurrentModificationExceptions

[sterile breach]

just simple async with schulder?

I have a hashmap, so instead I make a concurrenthashmap?

[lost matrix]

IO is short for Input/Output.
Some examples for IO are:

• Writing/Reading to/from a File
• Database access
• Requests to Websites

[lost matrix]

Should be fine

[sterile breach]

so in the event I just put my queries in the db? (I don't need to put any sleep?)

[lost matrix]

You can keep the sleeping in if you want to annoy your players

Let them wait in a limbo for minutes on end /s

[chrome beacon]

They will timeout

[sterile breach]

and in case of any problem with the db, I can refuse them the connection and display a message to them?

[lost matrix]

Correct. Look into the AsyncPlayerPreLoginEvent for this. You can kick them while logging in and
send them a message if something messes up in your DB.

[sterile breach]

passing my hashmap to concurrenthashmap can create probleme/errors?

[rotund ravine]

Huh?

Depends

[tame bay]

Yo. In the near past I saw a quite a lot of servers (1.20 etc.) which show an image of the players head in there scoreboard as an image. How does this works?

Is this also accomplished by texture packs or is there another way?

[lost matrix]

Screenshot?

[tame bay]

sec

currently not on my main pc so I had to screenshot it from a youtube video xD

[lost matrix]

Hmm. Do they appear somewhere else as well? Like in the chat or tab list?

[tame bay]

I´m not 100% sure since its been a while when I was on the server. But if I remember correct its only in the scoreboard

[lost matrix]

The only thing i could think of are resourcepacks. But that does scale horribly.

[tame bay]

They do have a custom server texturepack. But they cant probably replace everysone player head with a custom graphic and then automaticly reinstall the texture pack, I guess

[tame bay]

Yeah thats what I thought too

[wet breach]

Are you sure this is a scoreboard?

[eternal night]

@tame bay each pixel is its own char

negative space/back space magic is just enjoyable af

[wet breach]

Would still require resource pack right for the custom font?

[eternal night]

yea

[lost matrix]

I thought about that but then you would need a ton of chars for that.
Imagine a 256 bit color depth then you would need 256 x 8 images

[eternal night]

its 8bit iirc

[wet breach]

Well with 1.20 i think the easier way is display entities giving the appearance of a scoreboard

[lost matrix]

Thats what i mean. 8 bit is 256 colors

[wet breach]

This way you can use whatever images you want

[eternal night]

from the looks of it, they have 64 different colours ?

[lost matrix]

But wont this cause quite a bit of client side lag?
One image being 8x8 custom rendered chars...
10 head being 640 chars. And the network traffic as well if
you update this too often.

[eternal night]

eh ¯_(ツ)_/¯

[wet breach]

More of a reason to believe its a display entity and not an actual scoreboard

[eternal night]

Maybe its a fun shader

who knows

download the resource pack and check

[wet breach]

Assuming there is one lol

[eternal night]

I mean

server resource packs are still downloaded

there is a resource pack on that server

[wet breach]

I know they get downloaded but that is if the server specifies one

[eternal night]

that server does.

[wet breach]

Oh ok well i cant tell from the image lol

[eternal night]

just gotta know all servers in minecraft smh

[lost matrix]

Without a resourcepack this wont be really possible. They also removed the numbers from the scoreboard
and i think this requires a resourcepack as well

[wet breach]

Its possible with a display entity

And the missing numbers makes me think that as well

Just make the display entity move with the player at an offset and it gives the appearance of a scoreboard

[lost matrix]

Even with interpolation this could look whacky

Also writing on display entities is hard

[wet breach]

Why is it hard? No different then your typical hologram stuff

Just a new entity with a bit more features

[lost matrix]

The alignment and rotation is waay harder

[wet breach]

Well it may have more freedom in those regards that old holograms didnt have. But it shouldnt be an issue. But because it can rotate and align in more ways is nice because it does make for a better scoreboard replacement

But without more info or images though its hard to say one way or thr other but i believe its a display entity. Only makes sense because you dont need to bother with the resource pack for every player that joins

[lost matrix]

Ive tried writing UIs with the new display entities and i think its poopy

And it doesnt help that its resolution/FOV dependent

[wet breach]

Well that is how holograms always worked

[eternal night]

The scoreboard numbers are usually removed with core shaders these days

Thanks, I'll check it out rn, I'm reassured for my knowledge

[quiet ice]

Yeah thankfully it isn't as bad as 1.8 vs 1.20 in modding space

[shut mauve]

In 1.8 I couldn't do anything (e.g. custom villager, I had to use NMS, it was horrible), but now it sooooo easier

[tame bay]

@wet breach @lost matrix @eternal night thanks for your ideas. Im gonna try to hit up someone from there dev team. If I find something I let you know

[buoyant viper]

really comes down to modding (usually) being closer to bare metal (in this case, net.minecraft.* classes) tbh

bukkit is a pretty huge abstraction layer

[quiet ice]

thank god

[buoyant viper]

yeah

if someone had a mod engine that used an approach similar to craftbukkit itd defo be much less aids than dealing with stupid little things like mappings changed

some people did attempt that but not on the scale that bukkit did :v

[quaint mantle]

what do I use instead of the deprecated org.bukkit.ChatColor?

(paper, if that makes any difference)

is org.bukkit.ChatColor deprecated in spigot?

[wet breach]

one of these days I will make one of my implementations where basically I strip out the majority of Mojang code and implement the bukkit api

[buoyant viper]

im just talking about the abstraction of Minecraft to create a version-independent workspace

where stuff like Mappings dont play much of a part

they DO matter internally, but not for the actual development of plugins

[abstract sorrel]

is that a paper related error then?

[wet breach]

well that is because mappings are done already really

but yeah

my implementation will basically not be dependent on updates

[buoyant viper]

in a personal experience, client mappings played a key role in why a mod stopped working despite no significant changes to internals happening :P

on Forge

[wet breach]

in other words, the moment an update comes out I could in theory already be updated since it wouldn't rely on the mojang code

its not going to be a clean room implementation either

[buoyant viper]

meanwhile u can download a bukkit plugin thats 10+ years old n itll probably still work mostly as intended :p

[wet breach]

probably not unless its something that is simple and doesn't touch the player objects

player object stuff got moved around a little in the API

or the methods in the object

[buoyant viper]

true, it was an arguable example but mostly true for something like an MOTD plugin or announcer

[wet breach]

then you have that api version enforcement in the plugin.yml lol

which that is easy to add for your example

[quaint mantle]

hey anyone good with server optimazations

[buoyant viper]

the api-version tag is for like forward compat tho isnt it? like a "this plugin uses api of at LEAST this version"

[kind hatch]

It is.

[wet breach]

its so the server knows whether or not to use legacy api for it

which I am not a particular fan of

if a plugin has to use legacy api, already its unoptimal and cause your plugin to use more resources just because of it

or make the server work harder

since it has to translate

[golden turret]

whyyy

[buoyant viper]

skill issue, just dont use Lombok

[dull goblet]

I am using NMS, I want to create a custom glowstone dust, but make it so that the dust is not stackable. So I want to set the maxStacksize to 1. I'm new to NMS and have been looking through the code, but Item seems to be deprecated and I don't know what to do.

[wet breach]

you could just generate a random id to stick onto the item data

this would prevent it from stacking

[dull goblet]

Yeah but the item will be used in for example crates, so then it will always be the same copy of the item

Which will make it stack

[wet breach]

I don't follow

[quaint mantle]

Main plugin file: https://paste.gg/p/anonymous/71eae2a956264879952be933cbd39f42
Reload command: https://paste.gg/p/anonymous/fd5dd49e5dfd4fe690a0807363787986
My reloadConfigValues function doesn't seem to be working, in another file (my reload command) I'm using this function, the config variable doesn't seem to get updated even though I changed it a lot

[wet breach]

but you didn't change it

config never changed

[grizzled oasis]

Hi, i need to take randomly the x and z between two coordinate one min and max, i tried with random but it didn't go that well

[wet breach]

second assigning getConfig() to a variable makes little sense as it doesn't do anything different

I think you were wanting it to save?

if so, you need to call getConfig().save()

[quaint mantle]

nope, i'm trying to load the config again incase of a change

[wet breach]

then null it out

and then re-assign it

[quaint mantle]

alright

why would just straight up reassigning not work?

Alright, so just tested it out:

    public void reloadConfigValues() {
        config = null;
        config = getConfig();
    }

It's doing the same, not changing at all

[dull goblet]

So imagine if I create an Item with unique id 123, like by doing a command. I will have the unique glowstone dust. If i do the command again this time I will get glowstone 456 for example, these don't stack. Then when you want to use for exampmle a crate plugin or shop plugin (external), you input the item 123 into the rewards section. If someone wins that item it will also have unique id 123 which causes it to stack anyway.

[wet breach]

oh right, its the main config

[grizzled oasis]

you can use nbt and add a custom id to it

so in that way the wont stack but if the have the same nbt they works just fine

[quaint mantle]

so you have any idea?

[dull goblet]

but i want to prevent them ever having the same id, they can never stack

[wet breach]

reloadConfig()

forgot there is a method for reloading main config 🙂

[grizzled oasis]

then create your own crate plugin

or if you already made it

create a list that you keep track with the ids inside

[quaint mantle]

alright imma try it out

[grizzled oasis]

like 101, 102, 103, 104.2

etc

[wet breach]

most plugins don't copy the data of the item rather just track the item type

and for the not stacking part

it is what you asked, you said you didn't want them to stack

so now you do want them to stack?

[quaint mantle]

it finally works!

[dull goblet]

No i never want them to stack, no matter the situation

[quaint mantle]

thank you so much

[wet breach]

you are welcome

[grizzled oasis]

something to ask, really stupid and probably fast i need to take a X and Z and generate a number between the min and max of a region

[dull goblet]

Kind of like debug stick, it looks like a stick but it will never stack because the maxstacksize is 1 (because debug stick is a custom material, which you can't create i think). So I want to create an itemstack with a custom max stack size but idk if that's possible either

[wet breach]

ok, then test with whatever plugins you have for crate or shop and see if it actually cares about the data of the item or if it only cares about the type

if it only cares about the type then the custom data doesn't matter

and then all you have to do with your plugin that handles these custom items, is check if they have these things in their inventory

and if they do, apply random id

this takes care of the receiving part of the item from the shop

or crate or whatever

could you tell me, how i can spawn snowparticles in the whole world?

don't

Spawn them in a distance around each player.
But let the player only see their own particles.

Is that the full exception?

So you take damage once and it starts spamming your console with the damage event?

[sage patio]

it was because of canceling the event

using event.setDamage() fixes that

[lost matrix]

Btw you should give your InventoryHolder classes an onClick(InventoryClickEvent) method. Let it implement some interface HandledInventoryHolder.
Then you can do

InventoryHolder fromOpenInv = topInventory.getHolder();
if(fromOpenInv instanceof HandledInventoryHolder handled) {
  handled.onClick(event);
}

This way you wont have to touch your listener ever again.
Simply implement your interface and it works. Prevents you from
doing endless if-else clauses.

[sterile breach]

if I do it in async with a cancel event, there is no risk that the chat will be sent before the cancel?

[young knoll]

You shouldn't use holder in general

[abstract sorrel]

is it worth storing data from a config file into something like a hashmap so you don't need to access the config every time or is it just more efficient to access the config?

[lost matrix]

Try delaying by 2 or 3 ticks and see if that changes anything.

[eternal oxide]

using FileConfiguration its already in a Map

[lost matrix]

FileConfiguration is pretty much a Map<String, Object> internally

[abstract sorrel]

ok thanks

[lost matrix]

But you should def load everything into concrete classes when the server starts.
Dont randomly access configs within your code on runtime.

[young knoll]

You can't

You have to send a chat message

[lost matrix]

This is only possible through chat iirc

[sage patio]

is there anyway to get the saturation amount of a food?
from the itemstack/material

because canceling FoodLevelChangeEvent makes foods doesn't feed the player

[lost matrix]

❓

[sage patio]

well i don't want players hunger get changed by health regain

i'm making it -1 each minute

[lost matrix]

Alright, i think you found the GameRule for that already, right?

[sage patio]

yes

getServer().getWorlds().forEach(world -> world.setGameRule(GameRule.NATURAL_REGENERATION, false));

[lost matrix]

And whats the problem with your FoodLevelChangeEvent?

You want it to be cancelled, but not if the player eats something?

[sage patio]

I'm codding this plugin for my Roleplay server
if player gets damaged by guns or whatever they have to fill their health in medic, not by foods

and hunger doesn't affect by anything, for example health regain, because health regain event is already canceled

if i don't cancel FoodLevelChangeEvent somehow server does not understand the health regain event and rapidly takes hunger for health regain

and if i cancel the food level change, the Food items do not fill the hunger

so i want to fill the players hunger when they eat a food (using PlayerItemConsumeEvent)

[sage patio]

thats why i need this

[lost matrix]

One solution

@EventHandler
public void onFoodChange(FoodLevelChangeEvent event) {
  // Cancel every food lvl change which is not caused by food
  if(event.getItem() == null) {
    event.setCancelled(true);
  }
}

Another solution

  @EventHandler
  public void onFoodChange(FoodLevelChangeEvent event) {
    int before = event.getEntity().getFoodLevel();
    int after = event.getFoodLevel();
    int delta = after - before;
    // Only cancel event if the player loses food, but not when he gains some
    if(delta < 0) {
      event.setCancelled(true);
    }
  }

Or you can define custom food levels if you want to

  @EventHandler
  public void onConsume(PlayerItemConsumeEvent event) {
    Player player = event.getPlayer();
    ItemStack consumed = event.getItem();
    if(!this.isCustomFood(consumed)) {
      return;
    }
    int customFoodLevel = this.getCustomFoodLevel(consumed);
    player.setFoodLevel(player.getFoodLevel() + customFoodLevel);
  }

[river oracle]

https://paste.md-5.net/gipebenixe.cs so I'm a tad confused why... I can't add MineDown as a dependency. Gradle is complaining about missing repo, but I literally added the correct repo and double checked too

[remote swallow]

do you have minedown as a dep in other modules

[river oracle]

no

[sage patio]

thanks a lot, ig solution one takes the item from player's hands right?

so if he held a food in his hand everything changes

the second one is better, i'll use that, thanks again

[quaint mantle]

for to use hikaricp am i need spring boot ?

or hikaricp has maven for self

[remote swallow]

no, hikari has its own dep

[lost matrix]

To me it looks like you need reflections. Which can be tricky if you are using mappings because the
mapped class on runtime might as well be something completely different.

[quaint mantle]

btw for to use jpa or hibernate i need spring boot ?

[remote swallow]

doubt it

[quaint mantle]

I searched them, they all talk about spring boot

[remote swallow]

yeah you dont need spring for hiberante

[quaint mantle]

for jpa ?

[lost matrix]

You will find it as well when looking for tomcat, jetty, undertow etc
But you wont need spring boot for anything, ever

[quaint mantle]

jpa is for vanilla java ?

[remote swallow]

probably not

[quaint mantle]

alright

[lost matrix]

Hibernate implements the jpa standard

[quaint mantle]

but jpa is spring feature ?

[lost matrix]

No

[quaint mantle]

or vanilla java ?

[lost matrix]

Neither

[quaint mantle]

oh

so custom

[lost matrix]

Its a java enterprise standard like jcache

It simply defines a standardised approach to persistence

[daring schooner]

Yeah, i don't want to use it but i think i'll have to

I was hoping for some workaround 😂

[quaint mantle]

ah i was think jpa is maven depencency

[daring schooner]

aight, lets get to coding

🥲

In old spigot mappings it was accessible, wasn't it?

[quiet ice]

The chat message will only be sent after the events are fired

[lost matrix]

Well, there is a workaround. You can always read the bytebuf

[river oracle]

I think about to pull my hair out 😂

[quaint mantle]

now i will add hikari for connectionpool and i will add hibernate
wouldn't be a problem right?

[lost matrix]

Hibernate already includes hikari.
I wouldnt use hibernate for spigot plugins.
It requires quite a bit of experience to get right.

[quaint mantle]

spigot have a feature like hibernate ?

[lost matrix]

You should not check custom items by their name or lore.
Rather use the persistent data container of itemstacks and tag your items.

?pdc

[undone axle]

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

[quaint mantle]

i mean data object methods

nvm i got this

thx

[lost matrix]

Just write your data into files. Its the first step if you
want persitence. Databases can always be tackled later.

Sounds like a custom item to me...

Anyways.
EntityDamageByEntityEvent -> get attacker -> get item of attacker -> get ItemMeta of item -> check name, check lore

That is. So weird.

Wait are you on 1.8?
Because then i wouldnt be surprised.
Buggy ass, crumbling, ancient spigot version from last decade.

It changed a ton

[sage patio]

each public static method is access able from other plugins via Class.method?

[quaint mantle]

bro sry for my ping and i wonder this
im developing api plugin for my other plugins
this plugin will store some datas player_rank, player_money
but this plugin will be only for bungeecord
so could servers under bungeecord depend this api?

[lost matrix]

Every method is accessible from anywhere.
You just need them on the classpath.

[sage patio]

thanks

[lost matrix]

If i understand you correctly, then yes.

You can write your api platform independent

[timid hedge]

I am trying to check if the attackers held item is a stick with knockback 2 named §c§lSTICK but i dont know how to check the enchanted

if(((Player) attacker).getItemInHand().getItemMeta().equals("§c§lSTICk")

[lost matrix]

ItemMeta will never equal String

[quaint mantle]

api plugin will be in the bungeecord
but plugins depend to api, will be on servers under bungeecord

[lost matrix]

And how do you think this "connection" will be realised?

[quaint mantle]

sry i changed

google translate

😄

Thanks, I won't keep you busy

[lost matrix]

Take it slow. Split this into multiple lines.
Create one variable for each step.

[dawn plover]

hey, simple question

with the @EventHandler

if you have 2 of these with the same name, will they override eachother, or will they just live happy ever afhter
(inside the same or in different classes, with same or different events)

[lost matrix]

They can have the same name as long as they dont have the same event type (obvsly)

[dawn plover]

also when they are not in the same class

[lost matrix]

Thats fine. The Method objects are different.
In memory you will have the full path of your Method as identifier
com.beeme.kitpvp.listeners.CombatListener#onDamage(EntityDamageByEntityEvent)
So if you have another class or another parameter type, then the methods wont clash

[dawn plover]

oh wait, that is totally right, didnt think about it

aha, that makes it a lot more comfortable to work with lol, dont have to check the names anymore

[bitter rune]

If (memory.boolean > 0) this is under the block break event, it should fire if the boolean is greater than zero right?

[lost matrix]

lol

[icy beacon]

huh

[young knoll]

You can just do if (boolean) or if (!boolean)

[icy beacon]

can java booleans be compared to numerical values?

[eternal oxide]

yes

[bitter rune]

Sorry it's a double not boolean

[icy beacon]

for some reason i thought they couldn't lol

[icy beacon]

ok this makes much much more sense

[lost matrix]

Not directly

[bitter rune]

I'm learning... And very slow

[icy beacon]

title & subtitle

there are also fadeIn, stay and fadeOut values, but you don't have to change them

leave it blank

""

[lost matrix]

    if(Boolean.TRUE.equals(memory.bool) == true != !false) {

this is reminding me of the terrible-plugin

thought they were using a booleanfactory 😦

ok there is one

[bitter rune]

This currently doesn't fire, I feel like I'm missing calling the event itself but I'm not sure

[river oracle]

https://paste.md-5.net/gipebenixe.cs so I'm a tad confused why... I can't add MineDown as a dependency. Gradle is complaining about missing repo, but I literally added the correct repo and double checked too

[bitter rune]

Oh imgur link isn't even opening through discord anymore

[lost matrix]

The file just doesnt exist

[chrome beacon]

You need to be verified for embeds

[bitter rune]

I think I understand I need to put <= not just < trying it now

Yeah working now. I just guessed made sense in my head

[icy beacon]

is it a bad practice to use <version>LATEST</version> for a dependency? specifically it's a private api that i think i'll be updating frequently, but i will thus know exactly when and what is updated

[hazy parrot]

In general, yes

I mean if its private you would know when you make breaking change

But I wouldn't use latest anyway

[sterile breach]

Hi, to get the prefix for a player. The best method is using vault placeholder?

[young knoll]

In code you can use the vault api

[river oracle]

okay update turns out this is the cause of the issue removing this line from the publication fixes the error, but also doesn't push anything to the final jar

what is the event for a block being broken due to another block

like a torch or redstone

[onyx fjord]

physicsevent?

[small current]

can you show an example

[river oracle]

?jd-s

[undone axle]

https://hub.spigotmc.org/javadocs/spigot

[lost matrix]

Blocks cant really break other blocks. Maybe water and pistons. But those are covered by other events.

[river oracle]

yeah I can't find an even regardless

[young knoll]

BlockPhysicsEvent

[small current]

@lost matrix can i have a code

[lost matrix]

Sure

[small current]

tnx

[lost matrix]

    if(Boolean.TRUE.equals(memory.bool) == true != !false) {

    }

Here is "a code"

[small current]

tnx

fr give an example

[lost matrix]

You didnt even continue your question

[small current]

my friend needs it

the code

what is the event for a block being broken due to another block

the code for it

[lost matrix]

There is none. Blocks cant break other blocks.

[small current]

if i break a block

and redstone is on top

or water breaking it

[fervent prawn]

final String username="root";
        final String password="root";
        final String url = "jdbc:mysql://127.0.0.1:3306/?user=root";

        try {
            Connection connection = DriverManager.getConnection(url, username, password);
            PreparedStatement stmt1 = connection.prepareStatement("USE ladno");
            PreparedStatement stmt2 = connection.prepareStatement("SELECT * FROM points WHERE nickname LIKE '?'");
            stmt1.execute();
            stmt2.setString(1, player.getName());


            ResultSet results = stmt2.executeQuery();
            if (!results.next()) {
                Bukkit.getServer().getConsoleSender().sendMessage("Failed");
            } else {
                Bukkit.getServer().getConsoleSender().sendMessage("Success");
            }
        } catch (SQLException e) {
            Bukkit.getServer().getConsoleSender().sendMessage(e.getMessage());
        }```

This interrupts the work on the line "```stmt2.setString(1, player.getName());```" 
and I see in the console  ```Parameter index out of range (1 > number of parameters, which is 0)```.
What did I do wrong?

[icy beacon]

i don't think you should do '?' when escaping parameters in preparedstatements, just do ?

[young knoll]

^

[icy beacon]

i had a similar problem

[fervent prawn]

Oh, really. Thanks. I didn't think it was that easy

[icy beacon]

np

[lost matrix]

For the Water: BlockFromToEvent
For redstone on top of other Block: That should be covered by the BlockPhysicsEvent

can you give an example code

both of my hands are in cast

i cant search or try myself

i need the code for a friend who is not fluent in enlish

player.chat

[cinder abyss]

okay thanks

[icy beacon]

how exactly are you typing

left hand

is not broken, badly damaged

[icy beacon]

so you can just send the events to your friend and he can figure it out?

[small current]

why wont you helpp

ahhh

[icy beacon]

because i'm busy working on my own project and i don't know why i spend time distracting

[lost matrix]

Because thats not help, its spoon feeding

  @EventHandler
  public void onWaterFlow(BlockFromToEvent event) {
    if(event.getToBlock().getType() == Material.REDSTONE_WIRE) {

i need spoonfeed now

[icy beacon]

?spoon

[undone axle]

Spoonfeed a newbie for a day and they'll come back with more questions. Teach them to find their own answers and you'll both be better off: you won't get stuck answering the easy questions and they'll be much more productive than before.

also i need for block under breaking

[icy beacon]

looks like it's not your friend after all

[small current]

MY HANDS ARE IN CAST

[icy beacon]

you can still type quite fast it seems

so many flaws in these obvious lies

[small current]

left hand

[lost matrix]

Try BlockPhysicsEvent. Tell me if it works.

[icy beacon]

speaking as a professional liar ^^ (dark past)

[small current]

it calls a lot

[icy beacon]

limit the conditions

do you know the spoonfeed answer

[icy beacon]

olivo, can i ask you for some creative ideas? i'm trying to come up with the gui items for muting a player for: foul language, spam, and advertising

no idea what to use

[small current]

language use barrier

advertise use sign

spam idk

[icy beacon]

sign is a good one, foul language is i don't think so

[small current]

language use paper

or a map

[icy beacon]

good one

[small current]

spam use pork

as the food

[icy beacon]

i thought of it yeah

but idk

i want to resemble actually spamming

[small current]

hmm

arrow

sword

or rod

[vast ledge]

Snowball

[small current]

as in spamming it in pvp

[icy beacon]

i'll use a water bucket\

as in flooding

[small current]

snowball is a good one

[icy beacon]

i think water bucket works best for me, snowball is good too

[eternal oxide]

COme on Mojang, when do we get multi texture packs

[chrome beacon]

?

Like multiple server resource packs?

[eternal oxide]

yep

each plugin able to assign their own

Keyed resource pack system

[icy beacon]

ooo

[young knoll]

Someone really needs to make a auto merger

[eternal oxide]

7smile7 did

[young knoll]

Oh?

[eternal oxide]

sorry alex not smile

[young knoll]

Nah that's a program tho

[eternal oxide]

https://www.spigotmc.org/resources/resourcepackmerger.103875/

yep

we need support for multiple keyed packs

@tender shard Make your resource into a plugin

[young knoll]

And make it automatic at runtime

[eternal oxide]

it could even read a resource pack info from the plugin yml

[young knoll]

Just catch them as they are sent

And merge them then

[eternal oxide]

plugins would have to be compatible

perhaps a registry system for plugins

register their RP

[echo basalt]

plugins can register resource packs?
