So, ive ran into a bit of an issue, im trying to utilise Vaults Economy API, Ive copied the default setup from Vaults APIs github https://pastebin.com/c0FfnpFm,

#

Ive also set the Plugin to print the running services, in which i only get the Metrics and Permission

Yeah looks like rubbish to me. No idea, i dont use external libraries.

Does that not come shipped with the default?

lost matrix
# vast ledge Does that not come shipped with the default?

No Vault is just an empty communication pipeline for plugins. You need a plugin which actually implements the Economy interface.
You could also create your own Economy. Its only a few lines. The biggest part is storing and loading the data.

Thanks anyways 😄

# quaint mantle Perhaps you have a clear example? 
EnumSet<ClientboundPlayerInfoUpdatePacket.Action> actions = EnumSet.of(ClientboundPlayerInfoUpdatePacket.Action.ADD_PLAYER);
List<ServerPlayer> players = List.of(this);
ClientboundPlayerInfoUpdatePacket packet = new ClientboundPlayerInfoUpdatePacket(actions, players);
serverPlayer.connection.send(packet);

ignore the dumbness of this but is my brain correct in saying to see if its been like 20 min since an instant, i do thatInstant + 20 min is after now instant

lost matrix
#

You mean.... Instant?

remote swallow
#

yeah

lost matrix
#

Yeah an Instant is a point in time. So if you look at it after 20min then it will be 20min in the past.
If you add 20 min then it will be in the present. If you create a new Instant and add 20 min then it will be in the future.

idk if caffiene is worth it here because there isnt really much data being handled

You can opt for guava’s cache

#

Since guava is shipped w spigot

lost matrix
# remote swallow yeah

That could be one approach

if(lastGiven.isBefore(Instant.now().minus(20, ChronoUnit.MINUTES))) {

}

Or you can use Duration for this. Its maybe more clear to read:

Duration duration = Duration.between(lastGiven, Instant.now());
if(duration.compareTo(Duration.ofMinutes(20)) >= 0) {

}
remote swallow
#

i completely forgot about duration

lost matrix
#

The comparator of Duration is maybe a bit weird to read. I often fall back to millis because of that.

remote swallow
#

nothing on its time senitive and shouldnt cause bugs if its late a minute or so

lost matrix
# 
    Duration duration = Duration.between(lastGiven, Instant.now());
    long durationMillis = duration.toMillis();
    long twentyMinutesInMillis = Duration.ofMinutes(20).toMillis();
    if(durationMillis >= twentyMinutesInMillis) {

How do I transform a block display to rotate around the y axis but pivot the translation at the center of the block?

I currenty have this, but I can't seem to get the right rotation matrix to get the translation to account for the rotation offset

display.setInterpolationDelay(0);
display.setInterpolationDuration(tickInterval);
display.setTransformation(new Transformation(
  translation,
  new AxisAngle4f(angle, 0, 1, 0),
  display.getTransformation().getScale(),
  new AxisAngle4f()
));

LuckPerms has a data structure that revokes entries lazily

#

But caffeine can do it eagerly if you ask it to

lost matrix
# ivory sleet No not really

On a Caffeine cache? Im almost certain that entires are only updated on access unless you specify an Executor in the builder.

Idk if it always (as in by default) update eagerly or lazily, but I know you can configure it to your likings at least (:

remote swallow

ivory sleet
#

Anyway smile the reason iirc they do it eagerly is because of RemovalListeners

since those need to be accurately invoked when an entry should be removed

This seems to mess up the rotation pivot once again

The rotation seems to work fine until I make the final translation

#

hmm

zealous scroll
#

I want to make the block rotate around its axis (which I've achieved thanks to your matrix solution) but I also need to keep the original translation because it's needed in the interpolations made when the block follows the parabola

lost matrix
#

Ah and one more thing for the translation. I made a mistake for the pivot point.
first translate to -px -py -pz instead. And then with positive values back ofc.

#

Wait...

Nvm, just try composing of the matrices first

I actually tried that but it made the translation exacerbate the rotation by a bunch

            final Vector3f scale = transformation.getScale();
            final Matrix4f translationMatrix = new Matrix4f();
            translationMatrix.m03(translation.x);
            translationMatrix.m13(translation.y);
            translationMatrix.m23(translation.z);

            // Apply rotations
            Quaternionf rotation = new Quaternionf();
            transformation.getLeftRotation().mul(transformation.getRightRotation(), rotation);

            Matrix4f transformationMatrix = new Matrix4f();
            transformationMatrix.translate(scale.x / 2, scale.y / 2, scale.z / 2);
            transformationMatrix.rotate(rotation);

i need this commands for my plugin:

  • Useful commands (which I can write in more detail)
  • A system of currencies and ranks (ranks can be upgraded for currency and receive goodies for this, such as prefixes or increased income at work)
  • Works system
  • System of cases for currency
  • Donation privilege system
  • Authorization and protection system against bots
  • Regions system
  • Chat filter system

How many years do you think it will take to write such a plugin?

Alright then lets apply each operation using a full composition
t being our translation
p being our pivot point

| 1 0 0 tx |   | 1 0 0 px |   | R1 R2 R3 0 |   | 1 0 0 -px |
| 0 1 0 ty |   | 0 1 0 py |   | R4 R5 R6 0 |   | 1 0 0 -px |
| 0 0 1 tz | x | 0 0 1 pz | x | R7 R8 R9 0 | x | 0 0 1 -pz |
| 0 0 0 1  |   | 0 0 0 1  |   | 0  0  0  1 |   | 0 0 0  1  |

The main problem is finding the RX values because you would need to apply the Rodrigues rotation and
i dont remember how to calculate it. You need some sort of skewing for that...
Try to simply rotate the identity matrix instead of calculating the R values.

            translationMatrix.m13(translation.y);
            translationMatrix.m23(translation.z);

            final Matrix4f pivot = new Matrix4f().translate(scale.x / 2, scale.y / 2, scale.z / 2);
            final Matrix4f pivotN = new Matrix4f().translate(-scale.x / 2, -scale.y / 2, -scale.z / 2);

            // Apply rotations

            transformation.getLeftRotation().mul(transformation.getRightRotation(), rotation);
            Matrix4f rotationMatrix = new Matrix4f().rotate(rotation);

            Matrix4f transformationMatrix = translationMatrix.mul(pivot);

Class#isAssignableFrom in shambles

quiet ice
#

Meh, the amount of performance I gain from doing that is much less than the time I need to spend to figure out in which order I need to call it again

slender elbow
#

when was this about performance again?

quiet ice
#

Is it parent.isAssignableFrom(child) or child.isAssignableFrom(parent)? I keep forgetting, so I wouldn't risk going that route and forgetting it.

#

Obviously, passing Class<T> instances is a flawed design anyways.

Hello, I wanted to know if the player's head could be obtained with the skin he has.

If so, how do I do it?

Does somebody know how I can make commands disappear from the tab complete, if a player doesnt have the permission to use/see them?

quiet ice

it is not

#

congratulations

or, well, depends on how you see it

#

So AbstractMap.class.isAssignableFrom(HashMap.class) yields false? See, that is why I am afraid of using that method call.

Imma ask here this time. I am trying to set a command's permission message. The issue is that it will just give me "unknown or incomplete command" even though I registered the message

# left pine ok 
        ItemStack playerHead = new ItemStack(Material.PLAYER_HEAD);
        SkullMeta meta = (SkullMeta) playerHead.getItemMeta();

        OfflinePlayer player = Bukkit.getOfflinePlayer(playerName);
        if (player.hasPlayedBefore()) {
            meta.setOwningPlayer(player);
        } else {
            meta.setOwner(playerName);
        }

        playerHead.setItemMeta(meta);

        return playerHead;

This should probably work

Does somebody know how I can make commands disappear from the tab complete, if a player doesnt have the permission to use/see them?

quiet ice
#

But that doesn't make much sense anyways.

HashMap x = new HashMap();
AbstractMap y = x;

works. Hence, AbstractMap should be assignable from HashMap?

slender elbow
#

if by parent you mean superclass then yes

orchid gazelle
#

if you just use #setPermission on your Command

quiet ice
slender elbow
#

sure then

#

so?

orchid gazelle
inner mulch
orchid gazelle
#

Sure thing ;)

quiet ice
slender elbow
#

okay lol

inner mulch
orchid gazelle
#

You can call #setPermissionMessage on a Command

#

Which should define the failure message you get

quiet ice
slender elbow
#

:WeirdChamp:

inner mulch
orchid gazelle
#

Well yes but then it won't hide the command and so on

#

And the API thing should just work

quiet ice
#

Though I wonder if using an instanceof on an Unsafe#allocateInstance is much worse performance-wise than straight-up using isAsssignableFrom

inner mulch
#

wait, why cant u hide it if you do it like that

quiet ice
#

Given that evidently the only difference of note is the performance impact as Unsafe#allocateInstance doesn't run the constructor.
And perhaps JPMS

orchid gazelle
#

Idk why but it does lol

#

I do not understand why setPermissionMessage is implemented even though it seems to not work

ivory sleet
#

geol are you sure you mean isAssignableFrom and not just isInstance (iirc the name)

quiet ice
#

isAssignableFrom for sure exists. isInstance would be new to me

ivory sleet
#

cuz Class#isAssignableFrom checks the class relation, while Class#isInstance is just iirc a glorified instanceof

orchid gazelle
quiet ice
#

I am basically asking how much slower it would be to run unsafe.allocateInstance(clazz) instanceof MyClass versus MyClass.class.isAssignableFrom(clazz)

quiet ice
ivory sleet
#

Oh

#

May I ask why do this?

quiet ice
#

Which uses Class#newInstance instead

orchid gazelle
# quiet ice Hm?

This project mentions that it's a reimpl with the reason listed that mixins badly support usecases that are not "intended"

ivory sleet
#

I can say for sure allocateInstance is faster than newInstance

orchid gazelle
#

So does this micromixin contain a loader for spigot or sth?

ivory sleet
#

But then you could prob identify the type of the instance by a switch or Map<Class,V> where u pass the class

quiet ice
orchid gazelle
#

Yes I know part 2

#

Damn sad I almost had some hope that someone wrote some Agent for that

quiet ice
#

However Starloader's classloading architecture is very similar to bukkit's classloading so as a fork of cb/bukkit it would work.

orchid gazelle
#

I am not talking about forking

#

I am talking about dynamic agents reloading classes to apply mixins

#

So basically no fork or startup args or anything, just a plugin lifting the work

#

/hotswapping

quiet ice
#

Given that I haven't encountered that problem while modding galimulator I haven't looked at it.

orchid gazelle
#

Hm sad

#

I have been thinking and asking about that stuff for 2 years now

#

I know it's possible but I know I would not be able to do it lol

chrome beacon
#

You'd need startup args

orchid gazelle
#

No

#

Dynamic Java Agent

#

You inject your agent at runtime

#

Which reloads/hotswaps classes

quiet ice
#

When using agents it is actually better to use the spongeian implementation than the micromixin impl as latter was explicitly coded for classloader-based systems.

chrome beacon
quiet ice
#

So the only two areas where micromixin shines at is Java 6 (perhaps even Java 5 since people requested that in the past) and classloader-first architectures

orchid gazelle
quiet ice
#

Yeah, but it won't last forever

#

Alternativly look at where the loot table is used

wet breach
#

it depends what you are trying to accomplish. If you are trying to change what is dropped when a block is broken with random drops, then the loot table may be ideal

#

otherwise just use the drop method of blocks

should I make a new class to set all the gamerules

spark osprey
wet breach
#

is this class only just setting up the stuff?

quaint mantle
#

nah the world will be like a bukkit world

it's basically a wrapper

#

imo

#

so it might have stuff like

wet breach
#

in that case I would probably make it an inner class

quaint mantle
#

sendToSpawn

#

sendToSpawn(Player player)

#

etc

spark osprey
#

nooonie i thought u were smart

wet breach
#

well those are commands

#

which commands I would keep separated

quaint mantle
#

like to what

#

In theory it's all part of the gameworld tho

#

ah but yeah nah wait

wet breach
#

in theory but not even the bukkit api has it setup like that

quaint mantle
wet breach
#

that is to spawn an entity

quaint mantle
#

it's a command

wet breach
#

yes but no

quaint mantle
#

if I branch

#

off to another class

#

how would that work

wet breach
#

easily because the api lets you listen for commands already and you just only need to check the world someone is in

#

unless you also want to support console stuff

#

then it may be a bit more involved

#

but do remember, just because myself and others may say different things

#

it is your plugin after all 😉

quaint mantle
#

ok but here

#

let's say

#

the Location spawn object needs to be passed around everywhere

#

cause player death

#

out of bounds

#

etc

#

I would rather dependency inject the entire world with all the data

#

than just a single object

wet breach
#

well it should be the other way around

#

also the world object should mostly be static unless there is time it will be removed?

river oracle
wet breach
#

that is why I added the question mark

quaint mantle
#

ok

#

im tryna stay awya from static

#

like what if I want two game worlds

spark osprey
#

smae

wet breach
#

it does have its advantages

quaint mantle
#

yes ik

#

but im saying is that

#

imo

#

this is better for future dev

wet breach
#

if you think so, as I said it is your plugin so whatever you decide goes and really it is you who has to work on it. So not everything has to be about efficiency or best ideals, but also easy for you to maintain lol

#

but this project is perfect for you to learn how to use statics though

spark osprey
quaint mantle
#

bro

#

@wet breach why would I use static for this

#

cause ik my server gonna be VERY popular ima need

#

multiple game worlds

river oracle
#

Multiple game worlds? IMHO you should really only use one

#

Setup bungee

wet breach
#

there is other rules, but they are dependent on the scenario

quaint mantle
quaint mantle
#

idk u might be right

#

actually now that I think of it

wet breach
#

you just have to learn to not use a bunch of statics is all 😛

#

but some occasional ones are fine

quaint mantle
#

i just avoid static when it comes to abstraction

wet breach
#

but then you have stuff like enums which are static

#

so if you want to use an enum, then you can't avoid the staticness XD

river oracle
#

Enums are great and so is static

#

The reaction of someone who doesn't know how to use enums and static

quaint mantle
#

ima make this implement GameWorld

#

and make it all abstract

#

so i cant use static

Anyone know why i'm getting this problem when compiling with intelij and Maven? [ERROR] Malformed \uxxxx encoding.

#

I have checked my POM xml extensively, and it SHOULD work

#

May something be corrupted?

wet breach
#

where statics don't do good is in dynamic scenarios usually

quaint mantle
wet breach
#

only way I dealt with file encoding issues reliably is to delete the file and remake it, or use some option to ignore encodings

wet breach
#

they usually don't do good in those situations lol

quaint mantle
#

why

wet breach
#

because they are static and don't change, where as in a loop you are wanting change usually. It just depends on what it is that is static really

spark osprey
quaint mantle
#

what if i just make this class static

#

bruh

#

@wet breach

#

ok so i might just get rid of this whole class

but if I want to set the gamerules

#

And u have to use a requirenonnull or directly check if it's not null something like that

#

while true, an empty lore is null

I don't get it

drowsy cosmos
drowsy cosmos
# lethal coral I don't get it

You should probably be best with changing your structure. Instead of adding lore like that. You should add lore using parameters. Not sure whether it is lore() or setLore().

You can also do itemMeta.lore() == null instead in the if checks, iirc. That should negate the warning from IDE.

lethal coral
#

ended up doing this

    public ItemBuilder withLore(@NotNull String... text) {
        Objects.requireNonNull(text);
        itemMeta.lore(Arrays.stream(text).map(miniMessage::deserialize).toList());
        return this;
    }

will still look fine

Hi, I am in need of assistance please. I'm making a plugin where it changes mob attributes on spawn, and when I try spawning them in game, they don't. It makes the sound of them spawning in, just doesn't actually spawn them. I am trying to update this plugin, as I started working on it during 1.19.3, and it was working fine in that version. The version I'm trying this in is 1.20.1 on a 1.20 client w/ fabric mods (if that somehow matters). Here's an example case for Creepers:

Please let me know if any other details are needed, as I am relatively new to plugin coding.

How does dependencies via maven and bukkit even work I'm so confused

Does bukkit load all the projects into like one jar during runtime

#

like theoretically

#

a jar with a bunch if modules

#

Idk the analogy for ot

#

It

echo basalt
#

Y'know how each plugin has its own classloader

#

P sure that's involved

#

Basically it scans the yml file, downloads the deps into a cache folder and loads them accordingly

quaint mantle
#

Spigot does download deps from original jar?

#

@echo basalt so if I depend on something like luck perms how does that all work

#

and honestly what even happens when I depend in a regular maven project now that I think of it

#

like does it, during compilation, it compiles the dependency in the project

aw man

fallen lily
#

You can track combat with attack events

ivory sleet
#

would have to rely entirely on some api

fallen lily
#

It should be in mc

ivory sleet
#

there isn't really a way of telling whether someone is in combat or not, I mean you can define your own restrictions on what being in combat means

fallen lily
#

The game needs to know how you were killed to show the appropriate death message

#

Including player & entity combat

ivory sleet
fallen lily
#

fall damage, fire, void

#

Etc

ivory sleet
#

death message has nothing to do with whether a player is in combat or not

#

its just how they died

fallen lily
#

Well you obviously haven’t read far enough

ivory sleet
#

?

#

are you trolling or what?

fallen lily
#

I’m not…

ivory sleet
#

there is literally no such thing as being in combat

fallen lily
#

I can solemnly swear there is a combat tracker in NMS right now

ivory sleet
#

show me

tall dragon
#

so how does knowing my ass dropped in the void help in knowing wether i am in combat

fallen lily
# ivory sleet show me

If you can wait about 12 hours for me to finish work and wind down that would be bless

#

To further prove my point, combat tracking is also essential in the entity AI subsystem

#

So yes it is “tracked”

#

How far, that isn’t known to me right now

tall dragon
#

which does not extend to players?

#

yea entities can be " targeting" something sure

ivory sleet
#

you are straight up lying

#

the ai system just caches targets and entities during runtime

#

has nothing to do with combat

#

and has never been

#

there is something called a targetSelector and a goalSelector, these two have a set of goals that constantly tick to check where the entity may move and what the entity may target

#

nothing to do with combat

#

But chunks get regularly unloaded* If thats what you are asking

hybrid turret
#

nono, i just read in the readme for the api, that upon chunks being deleted no more data remains

Because it changes the classpath of the loaded classes. Meaning you will use your version of the lib

How do I fix the problem with the PlayerInteractEvent being fired twice when there is no item in their hand?

#

The PlayerInteractEvent may be called once per hand. If you only want code to be executed once, you can check the result of https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/player/PlayerInteractEvent.html#getHand(), then decide functionality.

For example, only executing code if the main hand was used:

@EventHandler
public void onPlayerInteract(PlayerInteractEvent event) {
    if (event.getHand() != EquipmentSlot.HAND) { // * if the hand used is NOT the main hand:
        return; // do not progress past this point  |
    }
    // provide functionality
}

Thanks

So this will just ignore the offhand completly right?

ehm ok?

lost matrix
#

Nvm everything is

#

What is the purpose of your lista

mellow snow
#

check how many block break a player

#

lista is italian, is list in english

lost matrix
#

Why do you merge the player into the map when he joins?
This will cause the value to shoot up when a player connects several times

tall dragon
#

pretty bold to assume someone is using xray if they break >= 6 blocks of diamond within the span of 500 seconds too

lost matrix
#

Just add him

lista.put(p.getUniqueId(), 0);
mellow snow
#

in console spam: lista is null

lost matrix
#

cooldowns is null. lista isnt.

mellow snow
#

i try lista.put before insert the cooldown

tall dragon
#

also show where ur registering it

#

prolly creating 2 instances too

mellow snow
#

First I try without cooldown, and then I add it

lost matrix
#

And here is the problem.
Every time a player breaks a block you delete the old map and create an empty one.

        //Commands
        getCommand("log").setExecutor(new logGroups(this));

        //Drop
        getServer().getPluginManager().registerEvents(new dropEvents(this), this);
        //Kill
        getServer().getPluginManager().registerEvents(new killEvents(this), this);

        //xray
        getServer().getPluginManager().registerEvents(new xrayEvents(this), this);

        this.saveDefaultConfig();
        config = this.getConfig();
    }
tall dragon
#

right thats fine

mellow snow
#

I remove it now

#

but It still not work

lost matrix
# 
    private final Map<UUID, Long> cooldowns = new HashMap<>();

And then remove the map creation out of your listener.
If you create an empty map every time, anyone breaks any block, then you dont
have to wonder why your code doesnt work. You just delete all your data constantly.

tall dragon
#

because cooldowns is null ;d

mellow snow
#

and now the cooldown is infite

#

:D

lilac dagger
#

the cooldown doesn't change, you have to make it work

#

Sys currenttimemilis - cooldowns.get uuid >= 1500

#

do stuff

mellow snow
#

how many seconds are 1500?

lilac dagger
#

a second and a half

#

1000ms = 1 s

mellow snow
#

doesn't work

lilac dagger
#

but if the server is laggy, you might wanna consider a sync task

mellow snow
#

now the plugin doesn't send the message

mellow snow
lilac dagger
#

it's definitely something wrong with the code still

#

do some prints

#

it's a good learning advice, you'll end up understanding how debugging works

mellow snow
#

thank

#

but if I'm writing here it's because I didn't found help on forum discusses or google

granite owl
#

when i pass a string to a C api via the jni, can and if so should i explicitly null terminate the string or does jni handle it for me?

tall dragon
mellow snow
#

and it's useless for you to tell me that I have to learn java or tell me other things that have nothing to do with the help on the cooldown. Or even worse I would say that insults can be avoided. I'm here to learn and have fun, I just asked for help.

Hi, what's the best way to prevent placing an Item into the Offhand? I already have a handler that cancels the PlayerSwapHandItemsEvent but it seems like there is no easy way to do it in the inventory

smoky anchor
granite owl
sick edge
smoky anchor
#

wouldn't you just do
if (slot == offhand)
dont();

granite owl
#

because theres lots of different events

#

pickup, swap, drag, placing

#

well pickup only when an item already is in the offhand

#

still

#

🤷‍♀️ gotta catch em all

#

also

#

u cant just say inventory this event

sick edge
#

Alright thx guys and one other question does TextColor not work in gui names and only NamedTextColor s?

granite owl
#

u first gotta check if its actually a player inv

#

not an anvil chest or whatever

#

cause theyre all inventories

#

not every inventory has an offhand item tho

sick edge
granite owl
#

unless u want nullptr exceptions

#

im sorry, null exceptions

remote swallow
#

Dont recommended stuff that wont work

eternal oxide
#

everyone should be on at least Java 11 now

#

8 is not a good version to use these days

#

I'd also never recommend Oracle, but thats personal due to their attempt to copyright an API.

tall dragon

and your cooldowns.put should replace your cooldowns.remove

Im on 17 xD
I want to get a start area in a world i generate? What is the best/most efficient method to do this? Should I create a structure file and somehow load it?

eternal oxide
#

it depends on teh size of your start area

sick edge
#

Not very big only like a 20x20 Glass Area

#

I could place the blocks directly I guess

eternal oxide
#

a couple of chunks, yeah create a Structure

sick edge
#

ok

#

And how would I load it do I like have to spawn a structure block and use it to place the structure or are there better ways?

eternal oxide
#

no, you can save it and it will create an nbt file for you. Include that in yoru jar

#

then load/place as you need

sick edge
#

With Spigot StructureManager?

eternal oxide
#

yes

can you obtain the server time in ticks without relying on the overworld?

tall dragon
#

is there such a thing as server time?

#

don't all worlds have their own time?

smoky oak
#

ye thats why im asking

real palm
#

Well, just start counting away from server start and when stopping (or reloading) save it, after "boot up" load from config and continue counting and so on. And by the seconds going by you can see the server time (not really good when implemented later on tho)

There you go. Remove your dependency and import json-simple.
What are you doing in the first place. Gson is the better lib for most things you would want to do with json.

i had it with highest priority before but it didnt change much, its not even showing "test works" when i send something in chat

use try catch
