Is there a simple way to check if an enchantment is illegal (above vanilla value)

[dawn flower]

how do i make replenish and make it take 1 of the drops?

i cant find a way to remove drops and make it work with external auto pickup plugins

Hello, I'm using com. github. Anon8281.universalScheduler. UniversalRunnable and with this code:```java
FallingLeaves.getScheduler().runTaskTimer(new UniversalRunnable() {
@Override
public void run() {
Location previousLocation = leaf.getLocation().clone();
Location nextLocation = previousLocation.clone().add(nextx, FALL_SPEED, nextz);

            if(nextLocation.getBlock().getType().isSolid()){
                leaf.remove();
                cancel();
            } else {
                leaf.teleport(nextLocation);
            }
        }
    }, 1L, 1L);```

I get this error: [22:30:33 WARN]: [FallingLeaves] Global task for FallingLeaves v1.0 generated an exception java.lang.IllegalStateException: Not scheduled yet at io.github.paulem.universalScheduler.UniversalRunnable.checkScheduled(UniversalRunnable.java:138) ~[dist-1.0.jar:?] at io.github.paulem.universalScheduler.UniversalRunnable.isCancelled(UniversalRunnable.java:23) ~[dist-1.0.jar:?] at io.github.paulem.fallingleaves.leaves.Leaf$1.run(Leaf.java:56) ~[dist-1.0.jar:?] at io.github.paulem.universalScheduler.foliaScheduler.FoliaScheduler.lambda$runTaskTimer$2(FoliaScheduler.java:65) ~[dist-1.0.jar:?] at io.papermc.paper.threadedregions.scheduler.FoliaGlobalRegionScheduler$GlobalScheduledTask.run(FoliaGlobalRegionScheduler.java:179) ~[paper-1.20.4.jar:?] at io.papermc.paper.threadedregions.scheduler.FoliaGlobalRegionScheduler.tick(FoliaGlobalRegionScheduler.java:37) ~[paper-1.20.4.jar:?] ...
I tried checking with isCancelled, but I can't find something to avoid this error

[dawn flower]

why not BukkitRunnable?

[remote swallow]

so it supports spigot, paper and folia

[cinder abyss]

exact

so, any idea?

I have searched everywhere but nothing helped me...

[dawn flower]

where is that code located?

[remote swallow]

im guessing its the cancel

[cinder abyss]

in a method to create an textdisplay and manipulating it with this scheduler after

TextDisplay leaf = spawnLocation.getWorld().spawn(spawnLocation, TextDisplay.class, (display) -> {
    display.setBillboard(Display.Billboard.CENTER);

    display.setBackgroundColor(Color.fromARGB(0, 0, 0, 0));
    display.setText(finalColor + "🍂");
    display.setBrightness(new Display.Brightness(5, 5));
});

double nextx = SafeRandom.generateDouble();
double nextz = SafeRandom.generateDouble();

FallingLeaves.getScheduler().runTaskTimer(new UniversalRunnable() {
    @Override
    public void run() {
        Location previousLocation = leaf.getLocation().clone();
        Location nextLocation = previousLocation.clone().add(nextx, FALL_SPEED, nextz);

        if(nextLocation.getBlock().getType().isSolid()){
            leaf.remove();
            cancel();
        } else {
            leaf.teleport(nextLocation);
        }
    }
}, 1L, 1L);```

[lost matrix]

Dont create a runnable for each leaf. Just start a runnable when the server starts, and add leafes to the runnable.

[cinder abyss]

humm good idea

so it'll solve this?

[dawn flower]

Task#isScheduled

try adding that condition

[cinder abyss]

I already tried x)

[cinder abyss]

I'll follow that, you're the magician x)

I'm trying to make my plugin the most optimized possible so it's perfect, thanks

[dawn flower]

you could also check try to run the code once before actually creating the timer, so it doesnt instantly cancel if it passes the condition

[young knoll]

Better write it in ASM then

[cinder abyss]

💀

[dawn flower]

so run this

Location previousLocation = leaf.getLocation().clone();
Location nextLocation = previousLocation.clone().add(nextx, FALL_SPEED, nextz);
if(nextLocation.getBlock().getType().isSolid()){``` before creating the task

[cinder abyss]

yeah good idea

I have something similar but not the same code

Humm, I'll have to do some PDC

[eternal oxide]

no need to clone the location as its already a clone

[cinder abyss]

Location are confusing, some method returns a location and some others return void and clone is not really required...

[ocean hollow]

itemmeta from itemstack can be null?

[cinder abyss]

you're doesn't have itemmeta...

[lost matrix]

Yes, for Air

[young knoll]

Only for air

[ocean hollow]

oh, thanks

java.util.ConcurrentModificationException: ???

[young knoll]

Trying to remove from a collection while looping over it most likely

[cinder abyss]

ooh

[young knoll]

Use an iterator

[cinder abyss]

humm

in type or List#iterator ?

[echo basalt]

removeIf

[cinder abyss]

wow wow wo

what should I do? x)

Here is my code```java
getScheduler().runTaskTimer(new UniversalRunnable() {
@Override
public void run() {
for(Player player : getServer().getOnlinePlayers()){
if(!player.isFlying() &&
!player.isSleeping() &&
!player.isDead() &&
!player.isInWater() &&
!player.isInvisible()) {

                List<Block> leavesBlocks = LeavesUtil.getSomeLeaves(player.getLocation(), 10);
                if (leavesBlocks == null) return;
                for (Block block : leavesBlocks) {
                    Location spawnLocation = block.getLocation().add(0, Leaf.FALL_SPEED, 0);
                    if(!spawnLocation.getBlock().getType().isSolid()){
                        Leaf.createLeaf(spawnLocation);
                    }
                }
            }
        }
    }
}, 20L, 40L);

getScheduler().runTaskTimer(new UniversalRunnable() {
    @Override
    public void run() {
        for(TextDisplay leaf : registeredLeaves){
            double nextx = SafeRandom.generateDouble();
            double nextz = SafeRandom.generateDouble();

            Location previousLocation = leaf.getLocation();
            Location nextLocation = previousLocation.add(nextx, Leaf.FALL_SPEED, nextz);

            if(nextLocation.getBlock().getType().isSolid()){
                registeredLeaves.remove(leaf);
                leaf.remove();
            } else {
                leaf.teleport(nextLocation);
            }
        }
    }
}, 1L, 1L);```

(I removed Location#clone)

[lost matrix]

Make registeredLeaves a LinkedList and call removeIf instead of iterating

[cinder abyss]

oh okay thanks

[lost matrix]

registeredLeaves.removeIf(leaf -> {
  if(isInvalid(leaf)) {
    return true;
  }
  // Do something with valid leaf
  return false;
});

[cinder abyss]

oh thanks

I replace is invalid by my condition?

Hummm```java
getScheduler().runTaskTimer(new UniversalRunnable() {
@Override
public void run() {
for (TextDisplay leaf : registeredLeaves) {
double nextx = SafeRandom.generateDouble();
double nextz = SafeRandom.generateDouble();

            Location previousLocation = leaf.getLocation();
            Location nextLocation = previousLocation.add(nextx, Leaf.FALL_SPEED, nextz);

            registeredLeaves.removeIf(leafToRemove -> {
                if(nextLocation.getBlock().getType().isSolid()) {
                    leaf.remove();
                    return true;
                }

                // Valid leaf
                leaf.teleport(nextLocation);
                return false;
            });
        }
    }
}, 1L, 1L);```

thanks, I'm going to try

[lost matrix]

This doesnt work

[cinder abyss]

yeah

It's stopping the other leaves

[lost matrix]

removeIf iterates over all leafs

[cinder abyss]

hummm

so I replace for (TextDisplay leaf : registeredLeaves) by removeIf ?

[lost matrix]

Yeag

[cinder abyss]

okay thanks

Really interesting LinkedList

it seems powerful

Here we go again```java
registeredLeaves.removeIf(leaf -> {
// PDC enregistrer variables nextx et nexty + PDC spécifique pour dire que c'est une feuille, supprimer toutes les feuilles existantes au démarrage du serveur
double nextx = SafeRandom.generateDouble();
double nextz = SafeRandom.generateDouble();

                Location previousLocation = leaf.getLocation();
                Location nextLocation = previousLocation.add(nextx, Leaf.FALL_SPEED, nextz);


                if(nextLocation.getBlock().getType().isSolid()) {
                    leaf.remove();
                    return true;
                }

                // Valid leaf
                leaf.teleport(nextLocation);
                return false;
            });```

it's working! Thanks 😄

I learned a new java skill x)

[twin venture]

anyone can give me some advices or ways to improve it? about my plugin code base iam working on? iam gonna screen share if anyone interested :-:

[twin venture]

someone told me programming is never ending learning process :0

[young knoll]

It is

Honestly most things are

[twin venture]

iam trying to push my self to learn more advanced stuff

like better ways for data handling , data strcuture

etc

[rapid vigil]

read Effective Java book :p

[twin venture]

did

[rapid vigil]

nice

[cinder abyss]

I'll also add a code where if the player doesn't see the leaf, then I'll not make it spawn

I could then make more leaves in front of him and getting better performances

[eternal oxide]

not simple to do as you have to account for 1st/3rd person view

[echo basalt]

oops was reaching out for my phone

[dusky wigeon]

how spawn entity in spigot ?

[eternal oxide]

World#spawn

[umbral ridge]

why does my entire os freeze for like half a second, or a quarter, when i click start.cmd for my minecraft server

even my audio freezes XD

[young knoll]

The server likes to use as much resources as possible when starting

[drowsy helm]

have you set a max heap size?

[umbral ridge]

How do you do that

[drowsy helm]

the -Xmx flag

[umbral ridge]

Yea I have it at 6GB

That's for startup, right?

[drowsy helm]

its just max heap allocation

[umbral ridge]

I think I've fixed it

Now it doesn't freeze my system anymore

[drowsy helm]

monitor the jar on startup, is it cpu or memory

[umbral ridge]

I've got 32gb of ram

[young knoll]

Is it dedodated ram

[umbral ridge]

dedicated?

It's a separate server I have at home yea XD

[wet breach]

Make sure to set minimum heap

-Xms6G -Xmx6G

Starting the server like this gives the server all the resources upfront and prevents some other issues with the heap when it starts out less then the max and then needs to increase its allocation

https://tenor.com/view/dedicated-ram-wam-super-kai64-gif-14754106

[remote swallow]

How many dedicated wams do i need to run doom

[vernal basalt]

is there a better way to make something that applies to the player for x amount of time they are ONLINE?

my solution was log the amount of time they have played and check if it's been more than x time since

is that the best way to do it?

[agile anvil]

How do you log your player time? Do you have a loop that runs every tick or so and increase a counter ?

[rough ibex]

Can you further elaborate what should happen

[vernal basalt]

let's say I give a "curse" to a player and for x time they try to do cirtain things other things happen

like they can't eat or something

and yeah would I have to have a repeating task that checks if player curses are over?

[agile anvil]

Are the curse time limited or "numbers of actions" limited?

[young knoll]

Store a timestamp of when the curse ends

Then check that when needed

[vernal basalt]

good idea

[wet breach]

Use pdc and store it in the player pdc

[vernal basalt]

1.12.2 😭

[wet breach]

No need for external saving of this data

[wet breach]

A good reason to update lol. Well just use a yaml file i guess. Should be sufficient.

[vernal basalt]

yeah

[ancient jackal]

Is there a recommended inv gui library out of the many out there

[native nexus]

InventoryFramework

https://github.com/stefvanschie/IF

[ancient jackal]

That XML looks powerful

[blazing ocean]

https://github.com/Noxcrew/interfaces-kotlin also exists

[upper hazel]

Is it possible to change the required level to receive enchantments from the enchantment table for a specific player by lowering it, for example, from level 30 to 15?

[warm mica]

I already wouldn't use it because it calls itself a framework

[native ruin]

There is a Enchantprepareevent or smth maybe you can have a look at that

[rotund ravine]

Seems like a you issue

[round solar]

the cpu is going to 107%/100%, just wanted to ask why is the cpu load so much and what can i do to reduce it?

[drowsy helm]

100% isnt really much, depends what cpu the server is using

[pseudo hazel]

100% means the cpu is fully utilized

if you dont get lag its perfect

[lost matrix]

If you want to find out which part of your server draws the most resources then i would recommend profiling with spark.
And make sure your CPU is utilized by the MC server and not another application. (Check with htop)

[drowsy helm]

they're most likely using a panel like ptero, which would be fully dockerized

doubt they would have other apps running on the container

[round solar]

alr

[round solar]

what about memory

any idea?

[lost matrix]

https://www.spigotmc.org/threads/guide-server-optimization⚡.283181/

@round solar

Decrease view distance, entities etc

[clever lantern]

how can i make a wall of barrier blocks to make player not enter certain area?
currently i am doing Location blockLocation = playerLocation.clone().add(playerLocation.getDirection()); but idk how to make a wall out of it

[lost matrix]

What do you know about the geometry of the wall?

[drowsy helm]

if its just a square use a bounding box and iterate the axis

[clever lantern]

currently i am taking move event and if its in area (rectangle) i am placing a block in front of a player

[lost matrix]

Do you want to actually place wall blocks or do you want only one player blocked.
Because placing a barrier block will prevent any player from going through.

[clever lantern]

i am using send block change

to block only one player

[lost matrix]

A hacked client can just walk right through fake blocks

Because they dont exist on the server

[clever lantern]

so just cancel player move event?

[drowsy helm]

would be glitchy

you could apply a velocity in the other diretion to shove them

[lost matrix]

I would just double up. Place barrier blocks and create a smaller area which throws the player back when he tries to enter (as a backup)

Tricky part is deciding when to place the wall.
Do you just send the entire wall to the player?

[clever lantern]

currently i wanted to place like 9 blocks in front of a player when he tries to enter the area

every time he tries to enter using player move event

[wet breach]

since cpus typically have multiple cores these days, 100% means 1 core is being used, but even then this isn't necessarily accurate

you could have 2 cores at 50% and that is still 100%

[warm mica]

Ok

Didn't know it's my issue if things are called wrong

[umbral ridge]

If I do that my system freezes for like 250ms when starting up

my entire windows freezes

Did you ai generate this..

no wonder it doesn't work

[eternal night]

statically importing a field named placedBlocks is crazy

[slate surge]

nah its in the main class of the plugin

now it works i thought that cancelling the event would work but it didnt xD

updated scripts XD

[smoky anchor]

this will not work, what
it has to throw concurrent modification exception

[slate surge]

works!

btw i am on 1.8.8

[smoky anchor]

doesn't matter, you can't remove/add stuff to a list if you're iterating over it like that
(also, you don't have to if the removableBlocks list is within the event method)

[slate surge]

uh oh

missed on that

[smoky anchor]

how the fuck can that run

[slate surge]

yeah forgot i am everytime creating that list

it works like a charm

[smoky anchor]

and it does not throw a single error ?
am I the one who is wrong here ?

guys pls help, I'm questioning my whole existance over this

[slate surge]

lol

[valid burrow]

whats the problem

[slate surge]

nope doesn't throw a single error

[slate surge]

@valid burrow u see anything wrong here?

[smoky anchor]

my problem is that the code this guy wrote should be throwing an exception at the last line

[valid burrow]

show the whole code where are the other lists

[valid burrow]

only if it actually contains anything

it’s probably empty

[round solar]

what plugin can i use to spawn players at the same place they left at?

[smoky anchor]

-> #help-server

[valid burrow]

that is default minecraft

[valid burrow]

oh god

[slate surge]

ok nvm

i didnt saw console

[valid burrow]

xd

[valid burrow]

this code wont work and even if it would theres a lot of improvment

dw though we can help you

[slate surge]

nah

[smoky anchor]

ok, good, I am not crazy

[slate surge]

XD

[valid burrow]

wdum nah xd

what exactly are u trying to do broski

remove certain blocks from the explosion?

[slate surge]

when i not added the removableBlocks.remove(location); it worked and when i added it i didnt tested it

so i tested it with and without it

with it throws error

and without no errors

[slate surge]

like the blocks placed by a PLAYER and in SURVIVAL can only be broken or destroyed with an exlosion

[valid burrow]

oh thats simple

but

[smoky anchor]

can't wait for players to place water and lava to make (cobble)stone

[slate surge]

they wont be able to

[valid burrow]

you should definitely use OOP cause u are making a gamemode

[slate surge]

cuz its a fireballfight

[slate surge]

huh?

[valid burrow]

you should have Instances of a game class

to seperate each session

[slate surge]

hmm

when the game finishes i made so the server would restart

[valid burrow]

well anyways jusr make a list IN THE EVENT CLASS

[slate surge]

and on one server

[umbral ridge]

you can use PDC on blocks that are placed by players and add a NamespacedKey...

[slate surge]

only one game can run

[valid burrow]

thats kinda pointless he can just cache

[umbral ridge]

in explosion, enumarate though the list, check PDC, etc..

[slate surge]

too complicated for me :D

[smoky anchor]

only for tile entities (unless you use alex's library)
But not needed

[slate surge]

plus when game shuts down i will loop thru the list and remove all blocks

[valid burrow]

dont do it

just make a Arraylist in the evnt class @slate surge

[umbral ridge]

who is alex and yeah PDC works only on tile entities

[valid burrow]

and make 2 listeners

one for placing

one for explosion

oh and one for manual breaking

[slate surge]

yeah

i have that

[valid burrow]

no

[umbral ridge]

what if server shuts down or reloads during the game

[valid burrow]

your lists are in your main class

[slate surge]

@EventHandler
    public void onBlockPlace(BlockPlaceEvent event)
    {
        if (event.getPlayer().getGameMode() == GameMode.SURVIVAL)
        {
            Location location = event.getBlock().getLocation();
            placedBlocks.add(location);
        }

    }

    @EventHandler
    public void onBlockBreak(BlockBreakEvent event)
    {

        if (event.getPlayer().getGameMode() == GameMode.CREATIVE)
        {
            return;
        }

        Location location = event.getBlock().getLocation();
        if (!placedBlocks.contains(location))
        {
            event.setCancelled(true);
            placedBlocks.remove(location);
            event.getPlayer().sendMessage(getFormattedMessage("&4 You can only break blocks placed during the game!"));
        }
    }```

[slate surge]

umm

ok so ig i will move the session based configuartion to a seprate class

[valid burrow]

just make ur lists of breakable blocks in the event class

and then make it private

and static

[slate surge]

i want to access the class thru multiple classes

[valid burrow]

then make a getter

[slate surge]

nah

its not gonna be a public plugin its gonna be only on my server

and nowhere else

[valid burrow]

so you just wanna do stuff wrong on purpose

ig so

[slate surge]

no

idc if its shit coded or not

if it works

it works

[valid burrow]

and it wont work if its shit coded

[slate surge]

it will

[valid burrow]

or it will be very inefficient

[slate surge]

the amount of shit coding is too much

in my plugis

[valid burrow]

all of your code is possible in like 40 lines in 1 class

[slate surge]

thats what i hav to account for

[umbral ridge]

for a starter any code is good DrVosss

[slate surge]

the entire plugin 💀

[slate surge]

my second plugin is this

[valid burrow]

yeah but thats no reason to not fix known mistakes

but so it be

[umbral ridge]

yeah that's ok, you'll learn through mistakes like we all do

[valid burrow]

its your plugin

[umbral ridge]

no its my plugin

XD

[valid burrow]

whut

[umbral ridge]

https://tenor.com/view/finding-nemo-mine-gif-3543068

[slate surge]

not your

XD

[slate surge]

yes

i making it from scratch

[valid burrow]

the part u showed me yes ofc not an entire gamemode

[slate surge]

XD

[smoky anchor]

If you do plan on making more stuff, you better start learning good practices early
It might be hard to re-learn how to do stuff the right way

[valid burrow]

event class:
placed blocks
3 listeners for modifying everything
public shutdown method to remove all blocks <- called from main on disable
getter for blocks if still necessary

thats it

Hello, If I want to make a system that does a specific thing when you for example kill a certain amount of zombies, am I forced to manage zombie kills for each player in order to do that? (Getting kills, setting kills and saving kills of zombies ofc)

[young knoll]

Yes

Well, I think statistics keep track of kills for each mob type, but it’s probably better to manage it yourself

[wet breach]

need to use aikar flags

[rapid vigil]

Well sort of, it saves statistics for all mob kills not a specific mob as far as I am aware. I need it only for 1 type and wanted to make sure I am forced to manage them myself because if there's already a way to access them then I don't need to bother managing it

[umbral ridge]

I am

[smoky anchor]

Mob kill statistics exist

[wet breach]

weird

[rapid vigil]

do you mean the Statistic enum?

[smoky anchor]

No, I mean the minecraft feature, idk how to access those from the API

[rapid vigil]

Yeah I am talking about an API feature

[young knoll]

It's in the api

[rapid vigil]

how do I access it

[young knoll]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/OfflinePlayer.html#getStatistic(org.bukkit.Statistic,org.bukkit.entity.EntityType)

[worldly ingot]

Yeah you want Player#getStatistic(Statistic, EntityType)

[young knoll]

The statistic would be KILL_ENTITY

[rapid vigil]

ooh I didnt know you can provide an entity, tysm :D

[calm lichen]

hello hello

[smoky anchor]

[calm lichen]

i have a quick question regarding the VaultAPI. basically i found a plugin project that one of my close friends had sent me years ago that had implemented the VaultAPI, and i spent pretty much all night just looking over all the code, reformatting, cleaning it up, etc, but for whatever reason the pom.xml file was missing so I made a new one and tried to implement the API myself however I am getting an error that basically says the 1.7 API isnt found. I cant seem to figure it out on my own whether it be due to exhaustion from staying up, just being dumb, or if it has something to do with the API itself.

[umbral ridge]

Does this statistics reset on player death?

[smoky anchor]

no

[lost matrix]

Sounds like he didnt have a maven project but you are trying to use it as one.
How do you compile your project?

[young knoll]

Isn't 1.7 gone

Since DMCA

[worldly ingot]

CraftBukkit is, yes

[worldly ingot]

No statistics are reset on death

[umbral ridge]

Ahh I see

that sucks

[calm lichen]

I'm using IntelliJ, made sure that I have maven installed and fully setup and everything before I started, it's been a hot minute since I've worked on anything so I just hopped onto this as a sort of refresher.

[young knoll]

Statistics are persistent

You can manually reset them tho

[umbral ridge]

So what now... do they reset on death or no

[calm lichen]

that would be unfortunate lol

[umbral ridge]

what do you mean by persistent

[young knoll]

no

Like PDC

[umbral ridge]

Then that's perfect

[lost matrix]

Alright, now how do you compile the project?

[young knoll]

They persist restarts and all that

[lost matrix]

*He is speaking about Vault v 1.7 not spigot 1.7

[umbral ridge]

too bad it doesn't have PLACED_BLOCK xD If it already has MINE_BLOCK ..

[smoky anchor]

it does im sure, probably used instead of placed ?

[calm lichen]

I was just running the main package that has all the files in it

and then taking the result out of the target folder

once its generated

[young knoll]

Yeah block placement is handled by USE_ITEM

[rapid vigil]

Just save blocks placed in a map :p

[worldly ingot]

Maybe my phrasing was a bit confusing because a single comma changes the whole meaning of the sentence lol. What I meant (and correctly wrote) was "There are no statistics that get reset on death"

[smoky anchor]

"time since last death"
that would "reset" upon death :D

[rapid vigil]

Well it would change not reset :p

[lost matrix]

If you want to use maven, then you should never manually add any jars to your project.
Every dependency should only be added to your pom.
After that you can only compile with the maven goals and not by "running the project" because this builds artifacts
on default, which ignores the pom.xml

so

1. Make sure to not have any dependencies added to the project
2. Check if your pom has all dependencies
3. Run the maven goals clean and then package (IJ has buttons on the top right for that)

[umbral ridge]

I could deal with that by saving it in per-player config but I was looking for a more... convenient solution lol

[molten hearth]

has anyone seen some packet visualizer like pakkit thats updated for 1.20.4

[rapid vigil]

Statistics are literally that but just already setup for you to use so you don't bother managing it

[umbral ridge]

Yeah so find placed block statistics for me

all about the BLOCK I can find is:

[rapid vigil]

Coll said it gets handled by USE_ITEM

[umbral ridge]

Ohhh

so it's all combined?

drinking, eating, blah blah blah

"USE"

[smoky anchor]

look it up on wiki, but yes

[calm lichen]

thanks, i thought some of the errors were related to the API but now it seems there are 16 completely unrelated errors that seem to be because the code is just old, so I'll have to figure those out before I'll be able to test it all out

[umbral ridge]

Well that sucks even more XD

[smoky anchor]

I mean, you can only place blocks, you can't eat them

[rapid vigil]

p.getStatistic(Statistic.USE_ITEM, Material.BONE_BLOCK); maybe something like this

[umbral ridge]

I mean I didn't know you could USE blocks, like eat them and stuff... As far as I know, you can PLACE them

[rapid vigil]

Not sure tho, i havent actually used it before iirc

[calm lichen]

nevermind, a lot more than 16... fml lol

[smoky anchor]

ye, my point is that for blocks, the only thing that will ever increase the stat is placing them

[rapid vigil]

USE is using something from your inventory, and when you place a block you are interacting with it which is also using it

[smoky anchor]

so effectively, it is "BLOCK_PLACE" stat

[twin venture]

Hi uhh , i have a problem i use CompletableFeature for my user loading

but its not loaded..

becuase when i try to grab the user :

it tells me null

[smoky anchor]

race condition ?
the loading completes after the PlayerJoinEvent gets fired would be my guess
but idk how completablefeature works

[lost matrix]

In the AsyncPlayerPreLoginEvent you should not start CompletableFutures.
Load your data blocking there

[twin venture]

ok so i should not use CompletableFeature in AsyncPlayerPreLoginEvent

[lost matrix]

Correct

But if you have a CF, then you should .join() it on the current thread

[rapid vigil]

its okay to use CompletableFeature in AsyncPlayerPreLoginEvent but dont use CompletableFuture :p

[shadow night]

Lol

[twin venture]

didn't understand you??

[shadow night]

Re-read your message and his message

[young knoll]

Yeah it's fine to use if you just .join it

[twin venture]

i removed the CompletableFeature

i think if i join it , there will be more bugs?

and some users won'e be loaded?

[young knoll]

Nah should be fine

Join just blocks until it's done

[twin venture]

what if 30 or 40 player's joining at the same time

would'nt that make it lagging a bit?

[lost matrix]

The AsyncPlayerPreLoinEvent is async. It doesnt run on the main thread.
You could just Thread.sleep() for a second there and the server wouldnt notice.

[shadow night]

On what thread does it run tho

[umbral ridge]

On a separate thread

[shadow night]

What about we sleep the netty thread

[umbral ridge]

Not recommended

[twin venture]

yeah iam not doing that

now it works

it load the user

[wet breach]

ah yes, lets disconnect the networking

[young knoll]

Pretty sure it runs on the netty thread

[lost matrix]

On one of the netty threads

[young knoll]

mhm

[umbral ridge]

Yeah but using a netty thread... not a good idea... unless if you need to do some weird shit XD Just use the spigots AsyncPlayerPreLoginEvent as it also runs on the same thread as netty so..

[eternal night]

[lost matrix]

[eternal night]

The login events run in the auth thread pool

[lost matrix]

Dont want to use the netty thread? Use the netty thread in the AsyncPlayerPreLoginEvent

[lost matrix]

Proof or didnt happen

[shadow owl]

Does anyone know of a good tutorial or library for creating packet-based holograms? I’m used to armorstand entities but heard packets are more efficient

how do i get these to work ^? im pretty sure once i get these working all the errors will be gone

[echo basalt]

It's not that hard

Let's start by doing it ourselves so we can learn a little

[echo basalt]

Import spigot, not spigot-api

You might need to run buildtools

[umbral ridge]

https://tenor.com/view/no-way-angry-shake-head-not-happening-upset-gif-14656457

[calm lichen]

i am dumb struggling to figure this out, i changed it to remove API in the dependancies, cleaned, and packaged, cleaned and compiled, and cleaned and built but no dice

[echo basalt]

Are you using maven/gradle or are you importing the dependency directly?

[calm lichen]

maven 🙂

[echo basalt]

Show me your pom.xml

[calm lichen]

i cannot verify my spigot account because i dont have access too the email I used and it wont let me use my other account so I cannot post images unfortunately, what would be the best way to send it your way

[echo basalt]

?paste

[undone axle]

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

[echo basalt]

If that doesn't work you can use other bins

I like sourceb.in

[calm lichen]

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

[echo basalt]

Yeah you're importing spigot 1.20.4 and you're trying to use 1.8 nms

[calm lichen]

yea this code is really old, i attempted to update to "import org.bukkit.craftbukkit.v1_17_R1.entity.CraftPlayer;" instead

[echo basalt]

That's still 1.17

You want 1_20_R3

For craftbukkit

And the rest is obfuscated

?mappings

[undone axle]

Compare different mappings with this website: https://mappings.cephx.dev

[echo basalt]

You can search the mojang equivalent here

Or map your pom.xml to use mojang mappings if you want to write NMS without a hassle

[sterile flicker]

Is anyone familiar with ocelot entity tracker? https://www.spigotmc.org/resources/ocelot.73853/

[echo basalt]

No, I've worked with that author before

Yeah that one

[dawn flower]

how do u get all configuration sections in a FileConfiguration

[echo basalt]

Loop through every key, get object, see if is section

And maybe recurse if needed

[dawn flower]

how do i loop through every key

[echo basalt]

getKeys

[dawn flower]

true or false for param

[eternal oxide]

pass each through https://hub.spigotmc.org/javadocs/spigot/org/bukkit/configuration/ConfigurationSection.html#isConfigurationSection(java.lang.String) to see if it's a section

[sterile flicker]

The fact is that I have such a problem custom NMS entity sometimes, if you go far away, appears in a suspended state at the player's position and then disappears when moving somewhere (that is, loading another chunk)? the fact is that I spawn a zombie and replace it with an id for an id npc while the player receives the PacketPlayOutSpawnEntityLiving packet. this way I get an NPC with AI, but if I move away, I sometimes see afterimages of the NPC, it strangely changes its position, maybe I should add handling of the npc unloading event this line java if (controller.isVisible(event.getSource(), getTrackerFor(zombie)) == BooleanResult.TRUE) { that uses Ocelot api did not fix the problem java @EventHandler public void onPlayerChunkLoad(PlayerChunkLoadEvent event) { for (CraftHusk zombie : manager.getZombiesInWorldChunk(event.getSource().getWorld(), event.getX(), event.getZ())) { if (controller.isVisible(event.getSource(), getTrackerFor(zombie)) == BooleanResult.TRUE) { System.out.println("zombie"); FakePlayer fakePlayer; try { fakePlayer = FakePlayer.create("", "", event.getSource().getWorld(), event.getSource().getLocation()); } catch (IOException e) { throw new RuntimeException(e); } event.getManager().showTo(event.getSource(), fakePlayer.getBukkitEntity(), zombie.getEntityId()); } } }

[dawn flower]

isConfigurationSection isn't static so i'm not sure where to get an instance

[sterile flicker]

code

[dawn flower]

nvm it's in FileConfiguration as well

👍

[echo basalt]

Are you sending a destroy packet when the chunk is unloaded?

[sterile flicker]

no

[echo basalt]

That can cause issues

Try it out

[echo basalt]

FileConfiguration implements ConfigurationSection

As it's a sort of root section

[sterile flicker]

I have the code for this, but the position of the NPC is changing. and the code will work to get static npcs in a chunk

Well, I'm confused about the positions

here's what I'm doing, how do I get the npcs to be destroyed?

[calm lichen]

Define api-version as 1.19

[lost matrix]

You go study

[eternal night]

I am waiting on the printer to print my three paragraphs of the hgb

[lost matrix]

lol

[peak jetty]

will that make it work with 1.20 as well?

[lost matrix]

Yes

[dawn flower]

raytrace or getTargetBlock?

?

[peak jetty]

why is this happening?

it happened when i changed from 1.20 to 1.19

[chrome beacon]

Trying to run 1.20 nms code on 1.19

that won't work

[lost matrix]

Because you are using nms. NMS and Craftbukkit are not compatible for multiple versions.
Thats why Spigot exists in the first place. Its compatible with multiple versions.

[peak jetty]

the error is happening in this meathod at EntityPlayer watcher = (EntityPlayer) ((CraftPlayer) target).getHandle();

[lost matrix]

You can only use spigot-api if you want your code to run on multiple versions.
Not net.minecraft.server (nms) imports and no CraftBukkit imports (like CraftPlayer)

[sterile flicker]

?

[peak jetty]

oh, is there a way to do the same thing using only spigot-api then?

[rough drift]

stop reposting the question

[peak jetty]

(i just forgot to ping so he probs didnt see it thats all)

[rough drift]

valid.

[lost matrix]

With ProtocolLib probably

[sterile flicker]

how do I get NPCs in an unloaded chunk through manager or tracker(ocelot) in 1.16.5 if an NPC with the same ID as a zombie was spawned to display zombies as an npc with AI?

I can't figure out how to send the destroy packet

[lost matrix]

I hope you have a manager that keeps track of that. Didnt i recommend you weeks ago to use libraries like citizens and LibsDisguises?

[sterile flicker]

yes, but my manager only tracks static NPCs and does not work on 1.16.5 with moving npcs or rather zombies, but something does not work

[peak jetty]

i have protocollib, i just dont know how to get the same function as EntityPlayer watcher = (EntityPlayer) ((CraftPlayer) target).getHandle(); without using craftbukkit

[sterile flicker]

I can't get zombies in a chunk

which is unloaded, and accordingly I cannot get the ID of the NPC

[sterile flicker]

my manager: https://pastes.dev/IdTzKrFKc5

can you look at getZombiesInWorldChunk method?

[lost matrix]

That class is not even close to a manager

[sterile flicker]

what can I do to improve it?

[dawn flower]

(item.hasItemMeta() && item.getItemMeta().hasDisplayName()) ? item.getItemMeta().getDisplayName() : item.getType().toString().replace("_", " ");

is this the best way to get the name of an item even if it's not named like Oak Planks? or is there a way to get the capitilizations correctly as well?

[wind blaze]

yo guys. Does anyone know if there’s an easy way to make an old plugin (1.7) usable for higher versions? 1.12 and up

[lost matrix]

The default name is a translatable component. The client decides how it is named.

[inner mulch]

I'd personally first of all remove all methods not related to the manager

you have some math operations in there that shouldnt be there

[dawn flower]

so that's the best way?

[inner mulch]

or some reflection utils which also shouldnt be there

[lost matrix]

In many cases a 1.7 plugin should work for 1.12

[wind blaze]

Oh sorry mistake on my side I meant mod like zip for own mod folder

[sterile flicker]

I still haven't figured out what to add to track of the NPCs and what should I do to make my class called "manager"?

[inner mulch]

i told you a few messages ago

[peak jetty]

?

[sterile flicker]

you told me what to delete, not what to add

[inner mulch]

btw remove the inner class as well

it doesnt make sense there

[sterile flicker]

without it, it cannot correctly compare the coordinates of the chunk

[inner mulch]

you can make it an outer class

i shouldnt be in your manager

[sterile flicker]

should I also move the hideFrom and showTo methods?

[glad prawn]

If it is used in another class, you should separate it

[inner mulch]

i wasnt quite there when the conversation started, what is ur manager managing?

npcs, right?

[sterile flicker]

custom zombies

[summer scroll]

How can I check if a player can has access to (break blocks, interact, etc) in specific location with PlayerInteractEvent respecting other plugins?

I found Player#breakBlock(boolean) but, it will actually break the block.

[inner mulch]

I'd make a custom entity class add the show, hide methods into the custom entity (if you want to make them packet based) then you can extend to make a custom zombie and you create a customentitymanager managing whatever you need to manage there

[peak jetty]

i saw online that i should create a different class for each version i want to support, how would i do that?

[lost matrix]

Sumeru why do you insist on writing this from scratch? I feel like you simply need more experience with writing spigot plugins
as well as general programming experience to pull this off. You are running against a wall for months now while continuing to
run into similar issues every day. There are libraries you can use which solved the hardest part for you already and let you focus
on writing content instead of building a system like that. Im 99% sure that what im seeing here will not work properly in the end
and will cause massive lags and instabilities for any server that tries to run this code.

Thats why im not answering to your "what can I do to improve it" questions anymore because ive tried giving you the fundamentals
weeks ago.

[shadow owl]

Is there a quick maven shade filter I can setup to exclude all other dependency plugin's plugin.yml's but still keep mine? I tried this but it removes my plugin.yml as well:

<filter>
    <artifact>*:*</artifact>
    <excludes>
        <exclude>module-info.class</exclude>
        <exclude>META-INF/MANIFEST.MF</exclude>
        <exclude>plugin.yml</exclude>
    </excludes>
</filter>

[wet breach]

create an include but set the artifact as your plugin

[lost matrix]

You should never shade a dependency which has a plugin.yml

[summer scroll]

Oh okay, thank you 🙂

[wet breach]

its valid to do so, it just depends whether or not the plugin relies on its main class or not

but even if it does, doesn't mean everything in it doesn't work

[shadow owl]

why not? doesn't it make it easier for the end user if they don't have to download and install another plugin?

[wet breach]

not necessarily

[shadow owl]

especially if the JAR im adding is a marketed as a shadable API?

[wet breach]

some plugins are not designed to run without their main class lol

[lost matrix]

In >95% of cases you will make the plugin you are shading completely useless

[wet breach]

not sure if its that great, I mean most of the time the plugin instance being passed in plugins doesn't need to be specific to which plugin

[dawn flower]

wouldn't shading a plugin cause issues since you're loading the plugin twice if there's 2 shaded plugins?

[wet breach]

since they are not making use of plugin specific things

[shadow owl]

This is the plugin im shading: https://www.spigotmc.org/resources/decentholograms-1-8-1-20-4-papi-support-no-dependencies.96927/

Does it not imply that I'm able to do this?

[wet breach]

this only happens if its main class is invoked

[dawn flower]

ah

[lost matrix]

Probably more like 98% honestly. I cant imagine a single plugin which works without their onEnable

[dawn flower]

you can add it as a provided dependency

[shadow owl]

But in that case you still have to have the plugin JAR installed on the server right?

[lost matrix]

Yeah this will 100% break

[wet breach]

I probably wouldn't say that much, as I said, most of the DI isn't specific to the plugin itself just that it needs a plugin instance. Unless it does a lot in its main class, you can easily work around the main class issue

[young knoll]

Yeah idk why it says that

[dawn flower]

better than causing issues in the future

[young knoll]

You aren't meant to shade it

https://wiki.decentholograms.eu/api/get-started/

[lost matrix]

If your dependency is another plugin, then the user has to download and install that plugin

[shadow owl]

Hi, I have a question with protocollib. So i search a way to force player to dl a texture pack with a custom prompt (for now i found only this to do what I need). I found a packet named "SEND_RESOURCE_PACK" with no infomation on the wiki.vg and on internet. Did you have information on this packet ???

[lost matrix]

A similar packet can be sent during configuration stage:

[lost matrix]

Why not?

Why do you want to use a packet in the first place?

Spigot has an API for this

Spigot has no API for intercepting packets. You need to use ProtocolLib for that.

[analog mantle]

This method looks really ugly.
What should I do to make it look more clean?

private List<String> getStrings(DangerUpdateEvent event, ItemMeta m) {
    final List<String> lore = new ArrayList<>(m.getLore() != null ? m.getLore() : List.of());
    if(m.getLore() == null) {
        lore.add(0, "Dangerous Item! Danger level: " + event.getNewDanger());
    } else {
        if (m.getLore().get(0).contains("Dangerous Item!")) {
            lore.set(0, "Dangerous Item! Danger level: " + event.getNewDanger());
        } else {
            lore.add(0, "Dangerous Item! Danger level: " + event.getNewDanger());
        }
    }
    return lore;
}

[rough drift]

use guard clauses

invert if statements and return instead of using else

[analog mantle]

To be clear, Intellij automatically generated that method because it was along the lines of 'extract thing from long surrounding method'

[inner mulch]

im pretty sure intellij doesnt change the method and just extracts it

[analog mantle]

alright

[inner mulch]

use guard cluases

it makes it more readable

[analog mantle]

I know what you mean but how can i apply it in that method

[inner mulch]

a

[analog mantle]

is this good?

private List<String> getStrings(DangerUpdateEvent event, ItemMeta m) {
    final List<String> lore = new ArrayList<>(m.getLore() != null ? m.getLore() : List.of());
    
    if (m.getLore() != null) {
        if (!m.getLore().get(0).contains("Dangerous Item!") && !m.getLore().get(0).contains("\uD83D\uDDE1")) {
            lore.add(0, "\uD83D\uDDE1 " + event.getNewDanger());
            return lore;
        }
        lore.set(0, "\uD83D\uDDE1 " + event.getNewDanger());
        return lore;
    }
    
    lore.add(0, "\uD83D\uDDE1 " + event.getNewDanger());
    return lore;
}

(I refactored the string to a simpler one)

[icy beacon]

For readability rename m to meta, that's my two cents

[eternal night]

If only one could store information in a form that wasn't lore on items

[icy beacon]

Valid

[analog mantle]

Besides that, it's good?

[inner mulch]

guard clauses

[icy beacon]

I'd probably need more context and try to do something else because it does kinda look ugly I agree

But I'll leave that to somebody else

[inner mulch]

and you probably want pdc

[icy beacon]

Wait true though

[analog mantle]

pdc?

[icy beacon]

Not good for storing data

[inner mulch]

?pdc

[undone axle]

[inner mulch]

dont compare strings, use pdc

[icy beacon]

And especially don't compare inventories by titles btw lol

[analog mantle]

I already use it

[icy beacon]

Why do you check for info with lore then

[icy beacon]

"i", "m", "j" PLEASE don't do that

I feel like I'm reading decompiled code

Invert this statement

if (m != null) {
    // do
}

Into this

if (m == null) {
    return;
}
// do

You'll have less intended code if you use these guard clauses in your code and it'll become more readable

[quiet ice]

it is a code style really

[icy beacon]

https://www.youtube.com/watch?v=CFRhGnuXG-4&pp=ygUgd2h5IHlvdSBzaG91bGRuJ3QgbmVzdCB5b3VyIGNvZGU%3D Cool video on this topic

[icy beacon]

Is it a code style to not have 10 levels of indentation?

I mean kinda yes you're right but like

[quiet ice]

E.g. at my school I am kinda banned from using break, continue and return unless there is no other way out. So you generally get a stupid amount of useless helper vars and stuff

[icy beacon]

Wtf

[quiet ice]

Mind you that most of my peers haven't programmed a lot of java. Hell, they wouldn't even know that hashmaps exist

[icy beacon]

That's on them lol

[quiet ice]

Yeah, but by extension teachers won't be able to understand more advanced programming paradigms because a person programming java in their free time for more than a year is a once in a lifetime event

[acoustic pendant]

How can i show a number like this: 3b, instead of the whole number?

[icy beacon]

Why wouldn't the teacher teach those who are not versed in Java yet

And be the experienced ones be

[quiet ice]

Integer.toHexString or something

[acoustic pendant]

but the number could be higher than integer limit

[quiet ice]

Though when there are no style rules that apply I do use continue, break and return rather frequently; but I wouldn't discourage from people using nesting.
More often than not, nesting is not a problem. These days we do not write code on paper, nor print it out on paper. With IDEs being able to scroll (I surmise that eclipse is even able of automatically scrolling), there really isn't a readability concern outside of reading github code or screenshots - but with code being generally a "write once, read never" affair, fanatic style guidelines are not necessarily a requirement.

[acoustic pendant]

nvm just Double.toHexString

i'll try that

[quiet ice]

What is your "number" defined as?

[acoustic pendant]

double

[quiet ice]

That exists?

[acoustic pendant]

it does

[icy beacon]

write once, read never
Sorry but I have to disagree with this mindset in regards of any maintained code.

You are right in the manner that IDEs do a lot of heavylifting for us, they allow us to see the start/end of a block, thus mitigating the problem of nesting for the most part

[quiet ice]

The only maintained code I really write are APIs, where there are more stringent rules - yes.

[acoustic pendant]

It is shown like this xd

[icy beacon]

But I also like reading my code with eyes, sometimes not using a mouse or anything

[acoustic pendant]

Double.toHexString didn't work

[icy beacon]

And when there's zero, one or, well, two indents in a function, it is much easier to read than if it is 10

[quiet ice]

Oh, you didn't want hexadecimal strings

[acoustic pendant]

Like, 500k, 5m or 10b

is that posible?

[quiet ice]

Should've specified it a bit further.
But no, there is no method that does it in java ready-made

[acoustic pendant]

I can do it checking the value I guess

[quiet ice]

You'll probably end up using a method such as

    public static String formatNumber(int number) {
        if (number < 1000) {
            return String.valueOf(number);
        }

        int exp = (int) (Math.log(number) / Math.log(1000));
        char unit = "kMBT".charAt(exp - 1);
        return String.format("%.2f%c", number / Math.pow(1000, exp), unit);
    }

(though this one is for ints [but easily portable to doubles] and not really efficent [e.g. constants could be cached], but at least it was an example I had easily at hand)

is there any plugin that add dinosorus and dragons like rlcraft ???/

[short plover]

I think you're in the wrong channel but yes MythicMobs and ModelEngine4 with Oraxen

how to set block

just get the block at that location and execute setType?

[empty temple]

noooo this is development channel . so i ask here ... if there isn't any plugin ... i will create one

[short plover]

Block#setType(Material)

[dawn flower]

ok

[twin venture]

i can show you the code i have rn .

getTime is : enum for diffrent types

the one i have is daily , so it should be 24h

[dawn flower]

what's the difference between getX and getBlockX?

[icy beacon]

I suggest you just run getMapList("nether_effects") and print the results (do the same with getConfigurationSection(..)) just to see what you get when running these and to know how to work with them

[icy beacon]

getX is not necessarily a whole number, e.g. 42.2348

[ocean hollow]

that works

[dawn flower]

ah

[icy beacon]

getBlockX is a whole number specifically denoting the X of the block

[twin venture]

this is the time i get :

[quiet ice]

and what is the problem here? Same as last time?

[twin venture]

yes the time is incorrect , and it dose not decrease

[golden turret]

how do i make intellij not generate .iml files?

[quiet ice]

Does it at least decrease each time you refresh the view? And how incorrect is it?

[twin venture]

no it does not do that , i was thinking about making a runnable for all online / offline players and it will decrease 1 second from it ..

but that's bad

[icy beacon]

I think you should save the timestamp of then the time should end and compare against it instead of saving its duration

the idea is that you write docs under another doc system like Sphinx

[dawn flower]

?

[rough ibex]

look at https://optifine.rtfd.io

[lost matrix]

I usually go for just-the-docs

[rough ibex]

this is written in rST for Sphinx

[dawn flower]

wait

so i have to read the docs to make docs

[rough ibex]

yes

[dawn flower]

then what did the person that made the docs that ill read to make the docs read

[lost matrix]

For just-the-docs you just have to write markdown.
Sphinx is built with python iirc

[dawn flower]

how do i even setup one before doing anything

[rough ibex]

sphinx uses python but is agnostic

for example linux uses it

[rough ibex]

it's an amalgamation

[young knoll]

If only we had a way to confirm

[dawn flower]

hypixel uses a fork of spigot at least

they have spigot-like stuff

[young knoll]

Well yeah

[echo basalt]

Was it spigot at the time?

[rough ibex]

a heavily modified fork of spigot

[shadow night]

They probably have rewritten minecraft already

packetevents may be helpful

https://github.com/retrooper/packetevents/

[blazing ocean]

https://github.com/retrooper/packetevents-example/blob/2.0/npc-tracker/src/main/java/main/PacketEventsPacketListener.java you can do stuff like this

[young knoll]

Does the event not fire before its sent to others

[sullen canyon]

I don't think there is a big difference between what I am trying to do with protocollib and packetevents lib

[lost matrix]

What are you trying to do?

[sullen canyon]

so, when a player texts something to a chat, it's checked and if the message is not appropriate it's not shown to other players who marked some words they don't want to see in the chat

[blazing ocean]

AsyncPlayerChatEvent

[lost matrix]

Sounds like you should just use the chat event

[sullen canyon]

ah yes I used it before, forgot to switch

tbh does not make any difference

[blazing ocean]

a lot simpler

[sullen canyon]

doesn't work for me if there is installed a chat plugin like essentials chat

[peak jetty]

does this only save config.yml?

[blazing ocean]

yep

[peak jetty]

how do i save messages.yml as well?

[blazing ocean]

pretty sure theres a save method

[lost matrix]

saveResource

[sullen canyon]

yea, this is what I get when I try the code above

[lost matrix]

The packet doesnt contain any String fileds

[blazing ocean]

is this plib

[worldly ingot]

I'm unsure why you're using a packet listener for this at all

The chat event's recipients list is mutable. You can remove recipients

You may completely destroy chat signing if that's the case, but I can't imagine you care much if you're hiding chat from specific users anyways

[peak jetty]

what does the replace true do?

[blazing ocean]

if it should replace the current file

[worldly ingot]

It will always overwrite the existing file on disk, yes

[lost matrix]

It replaces when its true

[peak jetty]

so if a player makes a change it wont let them?

[worldly ingot]

Pretty much

[blazing ocean]

on plugin load , yeah

[peak jetty]

oh so its gotta be false right?

[worldly ingot]

It will copy whatever values you have set in your plugin's binary

[blazing ocean]

usually yeah

[sullen canyon]

each user has his own list of words he does not want to see in the chat, so I actually have to account for all of them

[worldly ingot]

Yeah, that's fine. You can still adjust the recipients list

[blazing ocean]

in my case (very inefficient) i just cancel the event and broadcast the message to the players that can see it

[peak jetty]

how do i get the value of this from my messages.yml file?

[blazing ocean]

get()

[worldly ingot]

getString("prefix") :p

Does nobody have access to Javadocs or an IDE today?

[blazing ocean]

oh lmao

i tried that

[blazing ocean]

static in java is not very fun

[inner mulch]

dependency injection is better than static

[lost matrix]

Placeholders should have a unique symbol to determine their content.
Example:
#placeholder#
After that you parse all placeholders in a text. In this case the result would be placeholder.
This content can then be used for a hash lookup.

[sterile flicker]

https://imgur.com/a/cyACWNK what could be the reason for this result, as can be seen in the screenshot, the chunk in which the entity was spawned at certain coordinates was not loaded at the start of the plugin, but everything works fine when I call through the command

[inner mulch]

Thanks, one question do you know what O(?) means and some numbers? I heard hashmaps are fast because some O formula

[young knoll]

Smile is now writing an essay on big O notation

[blazing ocean]

im scared

[lost matrix]

The big O notation is used to describe time complexity of algorithms and data structures.
Its not a total description about how long something takes, but how well it scales with n (the number of elements).

For example a .contains() check on an ArrayList is O(n)
Meaning if
n = 1 -> 2ms
then
n = 20 -> 40ms
n = 100 -> 200ms
and so on.
So the time linearly scales with the number of elements in the list.

Hash structures usually have an average of O(1) meaning constant time.
n = 1 -> 2ms
n = 20 -> 2ms
n = 100 -> 2ms
This means it doesnt matter how many elements you have in the structure.

[young knoll]

Deprecated has runtime retention

So it should be visible

[shadow night]

What Big O does this have

[inner mulch]

Thanks, so hashmaps are extremely fast

[blazing ocean]

jesus reflection looks painful
