1 of 5 enchants

[gloomy thunder]

help

[tardy delta]

import it

[celest sonnet]

Did you try to make an event listener at the bottom? @errant shale

[eternal oxide]

you should not extend Enchantment

[errant shale]

no

[gloomy thunder]

help

[eternal oxide]

yes

[quaint mantle]

    @EventHandler
    public void mushroom(BlockSpreadEvent e) {
        if (e.getSource().getType() == Material.BROWN_MUSHROOM) {
            e.setCancelled(true);
        }
    }```
is that code true ? i tried but not working

i need getblock ?

[errant shale]

so is someone gonna help?

[celest sonnet]

What even are the errors tho

[hazy parrot]

you havent imported

[errant shale]

idk

[hazy parrot]

if you are not using notepad for programming, your ide should scream that you havent imported those classes

[errant shale]

this is what i got

[hazy parrot]

have you used chatgpt or smth ?

[errant shale]

im using IntelJI IDEA

no

• https://www.learnjavaonline.org/
• https://programmingbydoing.com/
• https://docs.oracle.com/javase/tutorial/java/index.html

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

[hazy parrot]

just put mouse on it -> alt + enter -> import class

[celest sonnet]

Or if that doesn’t work just click import class

[errant shale]

did

thx

but i have 1 more script

actually 2

[quaint mantle]

i tried getSource and getBlock event still not working is something wrong on my code ?

i cancelled all blockspreadevents and worked

i try with debug

[errant shale]

how to i send code again?

[quaint mantle]

😮

someone more annoying than me

[tardy delta]

?codeblocks

?codeblock

[undone axle]

You can use the discord code block format to display code or just text in a more pleasing way:
```java
public class MyPlugin extends JavaPlugin {
@Override
public void onEnable() {

}

}```
Becomes:

public class MyPlugin extends JavaPlugin {
    @Override
    public void onEnable() {

    }
}```

[quaint mantle]

i added debug and not working

[errant shale]

here

[young knoll]

Oh god <1.13

Pain

[quaint mantle]

getTypeid

is 1.13 method ?

[young knoll]

getTypeId is very old

Don't use it

[quaint mantle]

i changed

[young knoll]

you should still have access to getType in 1.12

[quaint mantle]

what u think for my code ?

i wanna cancel the mushroom spread

but didnt worked debug and event

    @EventHandler
    public void onBlockSpread(BlockSpreadEvent event) {
        if (event.getBlock().getType() == Material.BROWN_MUSHROOM) {
            event.setCancelled(true);
        }
    }```

looking

[mellow edge]

can I put TextComponent inside a book?

(and then make actions....)

[worldly ingot]

Yes. BookMeta#spigot()

[quaint mantle]

guys i wanna add cooldown to some events
event will not be available within 5 hours after running
for do this i need scheduler ?
if server close or crash tihs cooldown will work after restart ?

[eternal night]

it would not

[quaint mantle]

i need save cooldowns to some file ?
have a guide for this ?

i mean add cooldown to evets

[static cave]

Do you mean like. For Example: PlayerChatEvent can only be run every 5 hours?

[quaint mantle]

yes

or my method

[eternal night]

I mean

spigot has a config api

to read and write from config

could abuse that

[static cave]

you could save the Unix time of when you last ran it and then check if it has been 5 hours since then

[eternal night]

or just, simple java file read/write api

^

load on startup

write after use (if you can only use it every 5 hours, if its faster, maye only write on shutdown)

[quaint mantle]

alright

[halcyon temple]

just create the data and instad of creating scheduler just check the cooldown when the event is fired if it's important data you can write the data to file every 5min or something like that

[quiet ice]

String.format?

prettier in terms of what?

JSON formatting?

[static cave]

depends on what IDE you are using?

[tardy delta]

String#formatted

or wait for those new string templates

[static cave]

You can change that directly in Intellij

[quiet ice]

Ctrl + A & Ctrl + Shift + F on eclipse. Should also similarly work in IJ

[tardy delta]

ctrl alt l for ij on windows

[quiet ice]

I don't use auto-format these days though as it often does things that I'd rather not have in a very special usecase

[static cave]

Settings > Editor > Code Style > Java

you can change a bunch of stuff ther

[static cave]

@EventHandler
    public void onChat(PlayerChatEvent e) {
        FileConfiguration config = Main.getPlugin().getConfig();
        if(System.currentTimeMillis() <= config.getLong("lastrun") + 18000000) {
            e.setCancelled(true);
            return;
        }
        config.set("lastrun", System.currentTimeMillis());
        Main.getPlugin().saveConfig();
        // do stuff
    }

This should only allow the event to be run once every 5 hours. Haven't actually tested if it works though lmao

[marsh burrow]

yo, fellers, anyone know of a way to reigster a command on the fly? Im using commandMap, but only the console can execute the command, not players

[young knoll]

Can they not use it

Or does it just not show in tabcomplete

[marsh burrow]

neither

console on the left, player on the right

[young knoll]

Update their commands

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

[still adder]

when a player interacts with an "enchanted anvil", it is supposed to consume a certain item and perform a logic, but the player cannot do that. someone earlier said that the issue was that the event is cancelled immediately, but the issue is still there after fixing that. (or i fixed it wrong)

realized that the second image is barely readable, here's a pastebin. (https://pastebin.com/chV4hA6y)

[marsh burrow]

appreciate this, but still nothing, I even delayed it by 5 seconds when a player joins, and nothing

[quaint mantle]

yes learned unix

i wasnt know

Anyone got an idea what event to use when i want to convert concrete poweder once it hits water (as a item)

[young knoll]

You need a timer to keep checking if it's in water

[strong parcel]

Is there a way to listen for a block being destroyed by fire?

[young knoll]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/event/block/BlockBurnEvent.html

[quaint mantle]

well that sucks

isnt a droped item some kind of entity?

cant i listen to entity move event?

[young knoll]

That does not exist

[quaint mantle]

oh

there is no entity move event??ß

[young knoll]

Because it would be insanely laggy calling an event for every entity movement

[quaint mantle]

oh

okay

[quaint mantle]

so should i start a timer on player drop and after that check all the time durin the timer

[young knoll]

Pretty much

[strong parcel]

Thanks!

[young knoll]

Keep in mind that will not catch items that are not directly dropped by the player

[quaint mantle]

oh true..

[young knoll]

There is however an item spawn event

[quaint mantle]

alright

thx

[quaint mantle]

i asked chat gpt the same question and it told me BlockPhysicsEvent hes just dumb right?

[young knoll]

It’s not a block

[quaint mantle]

water is not a block?

[young knoll]

Dropped items aren’t a block

[quaint mantle]

i know that

[calm robin]

anyone have any sample code that i could look at where you used to update a players display name on tab, above their player and in chat with protocollib packet stuff?

im trying to add a prefix to player names and color their names

but it is different color depending on who is looking at them so im using packets

[celest sonnet]

Will checking every single player interact event cause lag?

like it only will work if you click a slime on to a piston, checking with if statement

[young knoll]

No

[celest sonnet]

oh ok

[young knoll]

Tons of plugins listen for that event

[marsh burrow]

Any idea why commands registered via CommandMap only console can execute?

[unique bay]

will using a plugin cause lag

[quiet ice]

haha, very funny

[young knoll]

I mean

Technically every plugin causes lag

[flint coyote]

Well not really. As long as everything stays below 50ms/tick it's technically not lag

[young knoll]

I guess it requires you to define lag as “an increase in load on the server”

[eternal oxide]

long

until 2035 or something

[flint coyote]

?scheduler

dang what was the command

[eternal oxide]

if (Instant.now().isAfter(timeStamp, ChronoUnit.MILLIS);

[young knoll]

You could do a repeating task

Or a delayed task

Yes

But it won’t be super accurate as it’s dependant on tps

Use an async task and then sync back to the main thread when doing the kick

runTaskLater is sync

You want runTaskLaterAsyncronously

[lavish robin]

How computationally expensive is a raytrace?

[young knoll]

It’s nothing that bad, the game does them all the time

[quaint mantle]

can someone link a guide on how to use yml files

[frail gale]

guys

IntellIJ Idea showing only blank screen, what can I do

[quaint mantle]

screenshot

[vocal cloud]

Restart or reinstall it?

[frail gale]

Hmmm, I fixed it

Deleted the entire data folder.

But, right now everything is like new haha, time to find the actual folder which is causing this issue

[quaint mantle]

there must be a better way to do this....

[young knoll]

Milliseconds to ticks should be fairly easy

1 tick is 50 milliseconds

[young knoll]

There’s probably a tag for concrete powder

Isn’t a Unix difference already in milliseconds

[obsidian plinth]

you around

[river oracle]

average day in Java Development

do you have UUID or player object?

if you have a player object they're likely online, but you can always check Player#isOnline

[young knoll]

If you have a uuid Bukkit.getPlayer(uuid) != null

[river oracle]

if you have a UUID you can use Bukkit.getOfflinePlayer(UUID) OfflinePlayer#isOnline

getPlayer is easier I suppose

[young knoll]

Either works tbh

[river oracle]

Player inherits OfflinePlayer so Player#isOnline is an what you could do

though its very unlikely they'll be offline unless you're doing heavy tasks

[quaint mantle]

am i missing something?

 private final VoidCrates main;
    public CrateRegister(VoidCrates main) {
        this.main=main;
    }
    File crateConfigFile = new File(main.getDataFolder(), "crates.yml");

"Variable 'main' might not have been initialized"

[young knoll]

If it’s an event though they are likely online

[young knoll]

Yes

[quaint mantle]

what

[halcyon temple]

just get name as a string and check if contains CONCERETE_POWDER

[young knoll]

Main isn’t set when instance variables are initialized inline like that

[quaint mantle]

it used to work before i swear

[eternal oxide]

you should not have a Player object if they are not online

[young knoll]

Initialize the file inside your constructor

[chrome beacon]

Switch or tag

[young knoll]

Or compile a set at startup

You can stream it

You should be careful holding reference to a player object

It’ll stop it from getting garbage collected when the player disconnects

Generally it’s better to hold the uuid instead

[halcyon temple]

yes you can

[eternal oxide]

yes you can

[halcyon temple]

player object has so much unnessarcy fields

so it's expensive to keeping it on memory

[fluid river]

yes rn

[young knoll]

Bukkit.getPlayer(uuid)

Check if not null, then kick

[obsidian plinth]

ur were the bungee guy right

[fluid river]

yeah but

i lost my old code sources

can you call/stream rn?

[obsidian plinth]

give me like 5 i broke sum lol

[fluid river]

?

[obsidian plinth]

yea where

here or private

[fluid river]

private ig

cuz stream

[obsidian plinth]

call me whenever

[quaint mantle]

did it with ends with now works too

[celest sonnet]

                    event.getPlayer().getInventory().remove(shear);
                    ((org.bukkit.inventory.meta.Damageable) shearMeta).setDamage(damage);
                    shear.setItemMeta(shearMeta);
                    event.getPlayer().getInventory().addItem(shear);```

oh fuck i do it wrong every time oml

anyone know whats wrong with this code?

[fluid river]

it doesn't work like this

you need to get meta, change it and apply back to itemstack

[celest sonnet]

oh

[fluid river]

Damageable shearMeta = shear.getItemMeta();
shearMeta.setDamage(damage);
shear.setItemMeta(shearMeta);

[celest sonnet]

also do you know why it wont let me just put Damageable?

[young knoll]

You’ve likely imported another damagable

[celest sonnet]

oh ur right i did the entity one im such a dumbass

[young knoll]

Make sure you import the right one

[marsh burrow]

I dont understand, this code should work, but only console can execute this new command

[young knoll]

Why are you registering a fake command

[river oracle]

Wtf is a fake command

[flint coyote]

a command that is fake smh

[river oracle]

CommandMap direct insertion make very real commands

Not fake ones

[young knoll]

Yeah but like

Why

[celest sonnet]

is it in the plugin file

[young knoll]

Are we too cool to register them the normal way :p

[river oracle]

https://github.com/Y2K-Media-Creations/ErisCL/blob/master/src/main/java/sh/miles/eriscl/simple/ErisBukkitBridge.java

[marsh burrow]

im adding the ability to get addons you can just drop into an expansions folder, but these addons need a command to work, cant just drop in into the plugin.yml file

[river oracle]

Nah it's just annoying and east to forget

[young knoll]

Then use a proper framework

Like ACF or cloud

[river oracle]

I'm too lazy atm to write a program that auto-generates the plugin commands on compile but I will eventually

[eternal oxide]

there are already command annotations

[flint coyote]

I do the same because I hate the plugin.yml

[remote swallow]

Gradle plug

[eternal oxide]

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

[flint coyote]

doesn't look that bad actually

[river oracle]

Wouldn't work for me as I need to update my command lib but I'll update it to work better

[marsh burrow]

oh sick, I will give this a try

[river oracle]

I'd just use acf lol

[quaint mantle]

how do i do colors in the console

[river oracle]

You don't

Unless you make your own console

[young knoll]

I believe you can with consoleSender

But why

[quaint mantle]

theres this plugin that makes colors in my console

[young knoll]

The console doesn’t need colors

[quaint mantle]

mine does

[flint coyote]

will it sudoku if it doesn't get colors?

[celest sonnet]

can an item not have meta? intellij keeps telling me to assert than item meta is not null....

[flint coyote]

well there is an @Nullable on it

Idk when it would be null though

[young knoll]

Air

[celest sonnet]

oh i see what it is thinking

[flint coyote]

It's not thinking anything.
IDE sees @coral knotable -> ide wants you to check for null

oh lol

[celest sonnet]

no i meant not what it was thinking but why it was happening sorry

[flint coyote]

Sorry for the ping, whoever null is

[celest sonnet]

i was confused cause the item meta being referred to was already shears like it had to be to get to that point in the code

so i wasnt understanding how it couldnt have meta but i realized that it doesnt like examine my entire code to figure it out

[flint coyote]

The IDE never has any logic to check whether it can actually be null. It's only driven by those annotations. Even after calling "hasItemMeta()" it will tell you that you should do a null check

You can savely ignore it

[noble lantern]

alternatively you can suppress warnings only reccomend that if you generally know what can be null though

sometimes intellij wants to warn me because i null checked something that was nested in another class and im not checking it in another, mad annoying

[eager jacinth]

Hello. I have a possibly strange question. I want to add caching to my plugin, but as you may know, maps return reference, which means I can **modify ** retrieved values as I please. This leads to the following problem: I retrieve a value from the cache, modify it, but forget to save it. What should I do in this situation? Should I always return a copy (clone) of the cached value?

[noble lantern]

If you edit an object in a HashMap (Say Player, and you set theyre health)

The object itself is changed inside the map, you dont need to "modify" or "save" anything

[river oracle]

Mmm you should probably be caching a data object tbh not a map that way you define how its edited much more clearly

I mean caching a map is fine but IMHO data object just makes more sense

[noble lantern]

Looked at it, never used that before but seems pretty cool, complicated as hell it seems from this javadoc

Looks overly complicated for something like an MC server 😛

Whats the benefits of JDO vs just shoving it to some type of map (for smaller datasets like mc servers)?

[river oracle]

Oh I just mean like getter setters etc

[noble lantern]

ohhh

Like a wrapper for the map essentially, i see

[river oracle]

Those are called Data Objects since they just contain data and provide 0 other purposes

Well no

I think we think the question asker means different things

I'm pretty sure he has a cache storing maps

Which works but I'd think is less functional than just using a Data Object

[zenith gate]

is there an event for when a trident comes back to the player?

i cant find anything on google

[noble lantern]

yeah then he said this; I retrieve a value from the cache, modify it, but forget to save it.

Which led me to belive he took the object in a map and replaced it redundantly, i did this for like my first 4 months of java cause i didnt know how OOP entirely worked 😛

[river oracle]

Maybe he is using a database and calling it a cache??

Too many questions

[noble lantern]

Maybe, need more info tbf

I just assume the most simplest thing most of the time

[river oracle]

So many buzzwords my brain is hurting

[noble lantern]

typically works

Remember

MC Plugins, not enterprise coding 😛

thouuugh

unit tests for plugins do be fire

[river oracle]

I unit test my plugins :P

[noble lantern]

i havent touched an ide in sooo long

[river oracle]

What do you do for work?

[noble lantern]

I do IHSS (in home supportive services) basically a in home nurse

[river oracle]

I seriously just code commissions while doing school

Cuz that's all I can

[noble lantern]

i get too bored of coding mc stuff and end up just playing games for long stretches of time

ik its been a fat minute since ive helped someone in here lol

[remote swallow]

hes so dedicated to the plugin grind he codes comissions while his gf is laying in his bed

[noble lantern]

someone on minehut showed me some insane new stuff with block displays on 1.19, had elevators and stuff it was so dope i wanna learn how to do that

[eager jacinth]

Maybe I didn't express myself correctly, but... that's exactly what I'm talking about! I add a player to the cache like this:

    public CompletableFuture<Optional<Profile>> getProfile(UUID uuid) {
        Profile cached = cache.get(uuid);
        if (cached != null) return CompletableFuture.completedFuture(Optional.of(cached));

        CompletableFuture<Optional<Profile>> fromDatabase = getFromDatabase(uuid);
        if (Bukkit.getPlayer(uuid) != null)
            fromDatabase.thenAccept(optionalProfile ->
                    optionalProfile.ifPresent(profile -> cache.put(uuid, profile)));

        return fromDatabase;
    }

And simply remove them from the map when they leave. After every change to the player, I save them to the database. But! If I retrieve a value from the cache (map), make some changes, and FORGET to save the changes to the database, then it's THE END

[noble lantern]

every change your saving to the database?

Why not run an async task, that flashes your cache into your database every x minutes (Even better, sync it with Minecrafts auto-save time that way you dont have data loss) This way whenever you retrieve a value from the cache, you know that if its modified its gonna get saved and you do not have to do anything extra (eg another line of code calling "saveToDatabase")

Also, why remove the player when they leave? What if they are relogging? You'll have to spend all that computing power loading they're data back again, just let they're data sit until a server reboot :p Im sure you arent gonna have gigabytes of cache laying around for some player data or similar

[wary topaz]

Bukkit.dispatchCommand(Bukkit.getConsoleSender(), "papi ecloud download Player");

[18:44:28] [Server thread/INFO]: Unknown command. Type "/help" for help.

Why is this happening? I've even tried it with a /

and since the place holder api says it will be removing registerExpansion in it i cant use that

[mortal hare]

could be that the command is handled not via bukkit api

but by brigadier dispatcher

or it could be that its the bungee command

[wary topaz]

so how could I manage to dispatch it?, and its a spigot server

[mortal hare]

are you running this server under bungee

[wary topaz]

no

[mortal hare]

you should look for developer api notes from placeholder api creators how to do this instead of relying on commands

[wary topaz]

well they dont say to use commands to register it in plugins

and you cant cause they removed the api feature for it

[noble lantern]

i would so use requireNonNull if it didnt look so god damn ugly in my code

[wary topaz]

just turn the null inspection off

[mortal hare]

you can always do reflections

[halcyon temple]

this will throw exception if the player is null

[noble lantern]

== null is essentially the same

[wary topaz]

ima just ask in the PAPI discord server

[mortal hare]

it will throw nullpointer exception anyways

[halcyon temple]

you can do something like that Optional.ofNullable(Bukkit.getPlayer(uuid)).ifPresent(p -> p.kick());

[mortal hare]

null.kick() will throw nullpointerexception

but it would be delayed by jvm

[marsh burrow]

@river oracle tried this api, but still, seems like commands cant be execute by players when making commands like this

[noble lantern]

good ol optionals

look into optionals, theyre godsend

[halcyon temple]

actually optionals are good

[mortal hare]

I believe optionals are good but overusing it isnt correct

for example i dont use optionals inside internal classes

[noble lantern]

i like using them for database libary purposes, null check hell goes crazy with mongodb

[halcyon temple]

i'm only using them for database methods

[mortal hare]

I've spammed optionals so hard back in the days

everywhere

constructors

methods

you name it

but each of that optional costs

a bit

so i've decided to not use it inside internal classes

[halcyon temple]

yeah i agree but i think it's better than Objects#requireNonNull for null check

[mortal hare]

1000%

[ivory sleet]

optionals suck

they're good when u return

[mortal hare]

unpopular opinion

[ivory sleet]

no

[eternal oxide]

I dislike Optionals too

[ivory sleet]

they suck because they dont have yes and no derivatives

so it fucks with overloading

[mortal hare]

is null and not null not enough for you?

[ivory sleet]

and type inheritance

null is fucked

but Optional is scarcely better

(just for returning)

[noble lantern]

you can use a Map.Entry

[mortal hare]

well in cpp you dont have null at all for objects

[halcyon temple]

wtf

[mortal hare]

but nullptr for pointers

[noble lantern]

i used a map.entry before one time to have 2 answers at one time, was whack but also cool at the same time

wtf

[ivory sleet]

u should have a

sealed interface Maybe<V> permits Yes, No {

}

this way u can subtype optional

[remote swallow]

please dont do that

null check first, then use an instance

[ivory sleet]

thats bad

dont do thty ithundxr

[mortal hare]

i still dont understand the usage of sealed classes

[halcyon temple]

just go for if (player !=null)

[noble lantern]

hear me out

Sometimes one liners are bad

[eager jacinth]

Hmm... I really hadn't thought about Async Task for cache saving. I've always seen separate methods for retrieving and saving in different APIs. I don't think there is such a "automatic" save as far as I understand.

As for removing on leave, I've seen many projects where developers use this practice. And keeping unnecessary values in the cache... I don't know, it doesn't seem right to me

[mortal hare]

they literally couple classes together

[ivory sleet]

now u're just creating throw away objects

[mortal hare]

^

[ivory sleet]

which is against effective java (unless certain stuff like builders)

compile time awareness of subtypes @mortal hare

[remote swallow]

save an instance

[mortal hare]

yea but it you need to define class name at the sealed class

which seems counter intuitive

in oop

[remote swallow]

Player player = Bukkit.getPlayer(uuid)
if (player != null) {
// that future but without optionals

[ivory sleet]

its not oop like yea

but java is multiparadigm

just look at optional that u were preaching about

[mortal hare]

yea statics

[remote swallow]

do that

check if its nullable, if it is isnt just get stuff from that, if it is just null check

what event is it

[ivory sleet]

just dont do this lol

like Optional... ofNullable... ifPresentOrElse...

[remote swallow]

yeah you can just use the event.getPlayer or Player player = ...

Hello, can anyone help me with this code? I need to modify this to spigotmc api. Couldn't find a solution for that.

[halcyon temple]

they are same

[noble lantern]

Yeah you would have to make the auto-save task, you can likely just shove it into a BukkitRunnable

Well, in order to avoid unnecessary caching you can just have different cache pools

IE, for some of my plugins I have the hard player data (money, levels, etc) that gets loaded on player join and STAYS loaded until a server restart, its just not worth the resources to keep loading/unloading it, and the size of the data is often time negligable

Then, for things like my KOTH events or auctions, etc I will clear that cache out every so often, as yeah it would get messy, I guess it just entirely depends on how your data is structured and how viable it is to leave stuff cached, in most cases as long as you aren't caching stuff in some type of loop without clearing it, your gonna be fine (from a memory leak standpoint)

Just remember, unused memory is free memory

[mortal hare]

i prefer declaring variable and then using it across the code

that way i can change the variable at any time

[ivory sleet]

^

cleaner also

[mortal hare]

it easier to refactor variable than bunch of function calls

[hazy parrot]

you have to define nonogram::Table<unsigned int>::Table<unsigned int> in cpp

had that problem few days ago

[mortal hare]

it doesnt work

[ivory sleet]

its also more readable

[mortal hare]

it complains

[hazy parrot]

literally had same error for three classes, i just added this

[mortal hare]

ooh

another clion user

what a rare find

[noble lantern]

wtf language is this

[mortal hare]

cpp

[hazy parrot]

its shit, i just like jetbrains products

[mortal hare]

eh better than visual studio for me

it runs faster

[hazy parrot]

had thrown std::bad_alloc and was debugging for two hours, i ran it in vs and error popped "you cant pop empty queue"

and that was reason of std::bad_alloc lol

phpstorm is superior for webdev

[mortal hare]

some people love apple products, i love jetbrains ones

[hazy parrot]

webstorm is specialized for js/ts, but if doing full stack app phpstorm is the way

[mortal hare]

literally everything that jetbrains made seems high quality

[thick gust]

😢

[livid dove]

Have ya'll not seen in line decleration in if statements before? Where it won't declare it if it comes back false? My brothers in christ lol

[remote swallow]

you didnt understand a word of what i said

check the javadocs say the event.getPlayer() is nullable, if it is null check it with an early return OR if it isnt just get it directly from the event.getPlayer

[livid dove]

Aye i did infact

misread

lol

mb

[thick gust]

This seems to work just fine:

    public static void removeNpc(EntityPlayer npc) {
        try {
            PacketPlayOutEntityDestroy packet = new PacketPlayOutEntityDestroy(npc.getBukkitEntity().getEntityId());
            for (Player all : Bukkit.getOnlinePlayers()){
                ((CraftPlayer)all).getHandle().playerConnection.sendPacket(packet);
            }
            npc.getBukkitEntity().remove();
            npcs.remove(npc);
        } catch(Exception ignored) {}
    }

[fierce salmon]

I made it so when players click items in their inventory, the event is cancelled. The problem is that when a player is in a random slot in their inventory and press a key corresponding to one of the slots in their hotbar, the item can still move there. What can I do to stop this from happening?

[livid dove]

What's the code?

[fierce salmon]

if (event.getClickedInventory().equals(event.getView().getBottomInventory())){
            if (event.getCurrentItem().getType() == Material.OAK_BOAT || event.getCurrentItem().getType() == Material.WATER_BUCKET || event.getCurrentItem().getType() == Material.WHITE_WOOL || event.getCurrentItem().getType() == Material.TNT){
                event.setCancelled(true);
            }
        }

[livid dove]

Well for one wacking all those items into a array or something and doing one check for if the array contains the item would be big brain.

2, ur better off looking up the click type method and working with those in ur checks too

[echo basalt]

I dare you to repeat getCurrentItem once more

[fierce salmon]

event.getCurrentItem() :p

[fierce salmon]

ty

[livid dove]

Also imullsion is right

If u need to call something 4 times in a row, uve screwed up

Imagine what that'd look like if u had 10 different menus with 9 items each.

That'd be one long ass if chain

[fierce salmon]

facts

but how do I check the click type?

[rare ether]

Hello, everyone. After extensive contemplation, I find myself on the verge of surrender. As a server owner, I am seeking a solution for a specific biome world generation. My objective is to create small, compact plains islands scattered throughout a Warm Ocean biome. These islands should maintain a distance of approximately 300-1000 blocks from one another. Despite my attempts to develop a custom data pack, progress has been limited due to complications with the worldgen folder. Additionally, I have experimented with plugins such as OTG and Islandcraft. However, OTG proved unsuccessful, and while Islandcraft functioned adequately, it lacked the desired biome compatibility and was only compatible up to version 1.12, whereas Warm Oceans were introduced in version 1.16. I would greatly appreciate any assistance or guidance in finding an alternative solution to this quandary. The accompanying image, created by myself, is provided solely to illustrate the envisioned aesthetic.

I cant upload the photo so DM if you want to see

[echo basalt]

What if (and hear me out).. you grab all the warm ocean world generation logic

and slap in the island generation present on the ocean biome

with a little programming magic

[brave sparrow]

slaps roof this bad boy can fit so many islands

[rare ether]

Ok you need to understand, you are probbaly gonna laugh at what ive tried. I downloaded visual code amd told ChatGPT to make me the code. it didn't work 😦 , Ive watched hours of datapack creation and i learned not much 😦

legit ive been making servers for a really long time and and mostly comprehead lots of code and copy paste types of things however this has been a challenge and i have no idea where to start

Other than my failure to create this type of world, what do you think about the idea of this type of generation?

[brave sparrow]

?learnjava

[undone axle]

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

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

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

If you want to find someone to do it for you

[rare ether]

how much would you say a project like this will cost?

give or take?

[brave sparrow]

I’ve never really done individual projects for hire, not sure

[rare ether]

Btw, ive gotten ban from Spigot I never understood why I filled out a ban appeal and i really dont understand why i gotten banned. Ive never broken any rules or did sus stuff you know anyone that could help with that

just asking because its kinda annoying how the site is blocking me so i need to delete cookies and make another account to see information

[echo basalt]

vpn

[rare ether]

will that do it?

[echo basalt]

no

spigot has a few rules

duplicate accounts aren't allowed

[rare ether]

Interesting.. so my home IP been blocked?

because i made alt accounts?

[echo basalt]

no clue lmao

but it's the most common

[rare ether]

thats wack

[echo basalt]

anyways a coupel basic notes

if you want services go on the official stuff and ask for them, never here

[rare ether]

by any chance could you give me more information on the island generation present? and how i could find it

[echo basalt]

uhh

[rare ether]

if possible you dont need to

[echo basalt]

Looking at the code

making a biome isn't that hard

trying to find where the nms code for islands on an ocean is

[rare ether]

ty

my journey continues 🥲

[echo basalt]

well

You'll need to make a plugin that uses nms to register a new biome that has your fancy generation

but

it's not THAT hard

[rare ether]

So making a plugin would be eaiser than a datapack

so java

[echo basalt]

P much

[rare ether]

ty for that

a better heading

[echo basalt]

yeah world generation is quite convoluted

apparently you want a warm beach biome with a climate that has a lot of "continentalness"

with a not-too-high temperature otherwise it only generates deserts

[rare ether]

Wish me luck im going to learn JDK and Eclipse

https://tenor.com/view/madagascar-private-its-no-good-i-dont-know-the-codes-codes-gif-23546774

[fierce salmon]

how do I make it so players can't use the F key to switch items to their off hand

[white root]

Could you just cancel the PlayerSwapHandItemsEvent?

[fierce salmon]

ty

[dire jewel]

where i can get gens plugin?

[quiet ice]

Hopefully it'll be easier in 1.20 and the enum refractor

[wet breach]

doubt it since its part of world generation unless 1.20 cleans that up

[quiet ice]

Well at least making it not an enum would allow for the possibility of future improvements

[wet breach]

maybe, just need to hope mojang doesn't do any weird or crazy things in regards to it

[oblique kettle]

is there a way to turn off the server-sided anticheat?

[wet breach]

sounds like you want to do some shady things

[oblique kettle]

how's that shady

[wet breach]

because if you are the server owner this isn't a question you would ask as you would simply do it

not sure why you think such a community as this would help you do shady things

or wouldn't point it out

[oblique kettle]

how can my question be related with anything shady

[wet breach]

I already told you

we are not dumb here o.O

[oblique kettle]

how is my question shady

[brave sparrow]

@wet breach I think they mean the vanilla anticheat lol

[oblique kettle]

I'm just looking for the programically way to do that since I received no response in #help-server

I just assumed that it was something that can be done with plugins

[brave sparrow]

It’s in your server.properties

[wet breach]

Lol, well this could be then

[brave sparrow]

It’s the allow-flight option

[wet breach]

Lol, sorry. Your question the way you have it phrased makes it sound like you want to obtain more knowledge to do something nefarious on servers

every once in a blue moon we get people like this

[oblique kettle]

it's ok, i understand lol

[oblique kettle]

what about the speed checks

[brave sparrow]

As far as I know it’s all bundled into allow-flight

If not, there’s not much you can do about it short of actually modifying the server afaik

[hybrid spoke]

there is an option for that

[brave sparrow]

Is there? Good to know

[hybrid spoke]

not sure if its named after the console spam "moving too quickly"

just know there is

[oblique kettle]

yeah that

[wet breach]

as far as programmatically goes, yes there is plugins that alter this stuff as well

I just don't know of any off top my head except NCP which allowed you to alter some things to your liking

[hybrid spoke]

ah its the elytra check as it seems

at least reddit says that

[oblique kettle]

yeah i was playing around with tridents with high riptide levels

wanted to get rid of the rubberbanding lol

[oblique kettle]

thanks, I'll look into that

[wet breach]

NCP = NoCheatPlus

not sure if has been updated at all to take in new things, but it did give you options to modify the values of some things like I said

        return false;
    }

[tardy delta]

you're blocking the main thread for too long

[sage patio]

very nice

and why?

[tardy delta]

cuz database calls take x hundred millis, one tick is max 50ms

do it async or block the async pre login event (async already so doesnt matter)

[sage patio]

i can't understand

connecting to the database tooks so long?

[tardy delta]

no executing the query

[sage patio]

it was fine on Java Connection

i switched to the HikariCP and this happens when someone joins

[sage patio]

also there are only 3 or 4 players, why does it have to take so long?

in the database

[tardy delta]

cuz databases are slow

especially sql ones

[sage patio]

^

my problem with Connection was that it kept dropping out all the time

[tardy delta]

probably still lagged, configure your connection pool better

[remote swallow]

do the sql async

and fuck you too discord

@sage patio do the sql async with completablefutures

[sage patio]

well to be honest i'm so mad today, i've deleted my custom plugin and decided to install one which its already made (GangPlus)

[remote swallow]

💀

[sage patio]

why should a fucking sql be fine with Connection and fucked up with Hikari

[remote swallow]

bc hikari uses connection pools

[sage patio]

well its not important any more

thanks for all help

[hybrid spoke]

[eternal oxide]

also use try with resources, as you are not closing your RS

[rapid trout]

Hi is there a way to make a player's item and armor invisible? I tried hidePlayer() but the problem is that the player couldn't be hit by other players anymore

[wet breach]

it sounds like a misconfiguration on your part in regards to hikari

[blissful pawn]

im not a modder, but I'd expect one can reuse elements from the Potion of Invisibility

[drowsy helm]

invisibility does the inverse of that

just use packets

[sullen marlin]

Entity#sendEquipmentChange

or something like that

[rapid trout]

and which package i can use for the item in main ?

[warm mica]

Not Hikari's fault if your code is trash

Do not execute blocking code on the main thread. Do not execute blocking code on the main thread. Do not ...

[hybrid spoke]

who?

[quiet ice]

stop the main thread

[flint coyote]

Exactly. Stop the main thread to execute blocking code on another thread

[round finch]

I love using the main thread and freeze the entire server

Good plugin idea

[hybrid spoke]

oh thats the /freeze command everyone always talks about

[flint coyote]

everytime someone mines a diamond you freeze the server for 5 seconds - just so everybody knows

A lot more visible than a chat message anyway

[round finch]

Exactly it is perfect

5 sec for each diamond

Couldn't be better

[flint coyote]

The question is: is a plugin considered harmful and deleted from spigot if it did exactly that?
But obviously mentions exactly that behaviour in the description?

In short: Is it harmful if it says it's harmful?

[wet breach]

there is a difference between harmful and malicious

[flint coyote]

Well I think freezing the server on purpose might aswell be malicious

As it's considered DOS

[wet breach]

well its not malicious if its made known that is what it does

[flint coyote]

By using a seperate thread. Or simply use Schedulers

[wet breach]

you can't unless you are making another thread that is not the main one sleep

[flint coyote]

Depends on your usecase. You rarely need your own thread

What do you want to achieve?

In that case you would use a repeating Task
https://www.spigotmc.org/wiki/scheduler-programming/

[quiet ice]

I got a plugin deleted off of spigot for being harmful even though it was advertised as such

So there is probably not much of a difference

[flint coyote]

The initial delay and the delay between runs. It's in the guide

[flint coyote]

what did it do?

[quiet ice]

Generic trolling plugin iirc

[hybrid spoke]

"hah i will troll the user by giving him op"

[quiet ice]

Yeah it was that sort of stuff

[flint coyote]

And troll the whole server by shutting down 12 times a day

[quiet ice]

It was more of a backdoor

[young knoll]

Can’t imagine why a backdoor would be removed

[tardy delta]

scary

[quiet ice]

Open source backdoor????
Impossible.

[flint coyote]

Lmao

Like people watch open source code before installing

That's not open source, you are lucky

If it was community edition however...

https://github.com/MilkBowl/VaultAPI & follow the instructions

[muted dirge]

bruh im saying

RegisteredServiceProvider<Economy> rsp = getServer().getServicesManager().getRegistration(Economy.class);

Is null

[young knoll]

Also make sure you have an economy plugin installed

[muted dirge]

oh

[river oracle]

Essentials is one

[muted dirge]

thanks for reminding me

[flint coyote]

it does, what else would be the reason for it?

[muted dirge]

trash

[hybrid spoke]

you yes

[muted dirge]

like u

[flint coyote]

Softdepend is just "load when it's there or ignore it" while depend is "if it's not there don't load this plugin"

[muted dirge]

thanks for your help guys ❤️

[hybrid spoke]

i at least know how to install a plugin

take the L

yeah okay i auto deploy

[river oracle]

There are weird edge cases where it wouldn't, but yeah it almost always works like that. I think I was just thinking about circular dependency which would just break regular depend too

Frrr

[flint coyote]

reversedepend: this

[hybrid spoke]

if i depend on them and mine loads first i will spam your github with issues

[flint coyote]

Time to delete the repo

[young knoll]

loadbefore: spigot

[hybrid spoke]

then the spigot 1 star reviews fly in

[flint coyote]

this is the way

[muted dirge]

what time is it

[flint coyote]

Well if it does its job and never mentions a developer api you are out of luck

[river oracle]

Idk you tell me

[flint coyote]

isn't time relative? who knows what time it is

[hybrid spoke]

its my good right to review any plugin i want with 1 star and make up some facts

[muted dirge]

3:15 PM

[flint coyote]

Saying "The non-existing developer api does not work" will look weird though.

[hybrid spoke]

and?

[vocal cloud]

<t:1685965506>

[flint coyote]

Idk that's just rude. That's like buying a car without wheels and then writing a review that the car does not drive

[hybrid spoke]

sounds about right

[flint coyote]

It's not like you knew it probably won't drive

[hybrid spoke]

but it doesnt

so i can review that

[flint coyote]

I mean you would tell the truth. But the 1 star rating would be kinda weird

[hybrid spoke]

i can live with that

[flint coyote]

Well then

[hybrid spoke]

now i will look for fabsi on spigot and begin my journey

[flint coyote]

If that's what makes you happy

[river oracle]

No its not

[hybrid spoke]

i will never be

[muted dirge]

yes it is

[flint coyote]

You have to write more code

Coding is love

[muted dirge]

where are you from

[hybrid spoke]

coding is depression

[flint coyote]

only if it doesn't work

As soon as you fixed that annoying bug that you searched 2 hours for it's big yay

[hybrid spoke]

if it works its a "won, but at what cost" since its work related

[flint coyote]

I'm not talking about coding for work

I don't enjoy coding for my work either

mostly because of all that shitty legacy support I have to deal with though

[dire marsh]

Don't deal with it then

[hybrid spoke]

the only thing that makes me at least a bit happy is a fancy UI

[flint coyote]

customers will be mad

[hybrid spoke]

since im a backend guy

but coding for every day for a decade now also has its downsides

[flint coyote]

I hate building UIs

[hybrid spoke]

me too

thats why im happy if its fancy

[dire marsh]

unfortunately the only way we're gonna make people stop using legacy versions is if all developers refuse to support them

[flint coyote]

oh yeah as long as I don't have to build it, that's great

[hybrid spoke]

thats not how it works

[dire marsh]

but it is

[hybrid spoke]

not in a business environment

[dire marsh]

if plugins keep supporting 1.8 then people feel like they have a right to plugins supporting legacy versions

[flint coyote]

Well if you distribute software you kinda have to support it for a few versions/years

I won't support 1.8 or any legacy minecraft version - ever.
I was talking about commercial/business development

[hybrid spoke]

if we would drop our legacy shit 70% of the software wouldnt work anymore

[flint coyote]

sadly that's true

[hybrid spoke]

and rewrite it would cost too much

so we just stumble over it with both eyes closed

[flint coyote]

Everybody loves technical debt

except the developers ofc

[river oracle]

Cant wait to get a job and be writing 20 year old backend in nodejs while wanting to die the whole time

[flint coyote]

You should work with banks

They pay well

and are always 10 years behind in technology

(or more)

[eternal night]

can also recommend ^

[hybrid spoke]

dont they use assembler

[flint coyote]

cobol mostly

[eternal night]

you are thinking of cobol yea

[river oracle]

Guys the decimal number are longn

Cobol is awesome

[eternal night]

I mean, its free money with cobols decimal math

[river oracle]

Is their even a language with that much precision besides cobol

[echo basalt]

tfw the tech debt is older than you

[wise mesa]

is a player object safe to use after a respawn

[flint coyote]

The player object does not change after death afaik

[eternal oxide]

do not hold references to Player objects

[flint coyote]

You can if you wipe the data on disconnect

[eternal oxide]

bad practice

use UUID and you have no cleanup to do

[flint coyote]

I would argue with that statement. It's perfectly fine to hold a player object if you wipe the data on a disconnect anyway.

Not cleaning on disconnect is bad pratice

[eternal oxide]

No

[flint coyote]

why keep data in memory when it's no longer required

[undone axle]

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

[eternal oxide]

Holding a reference to a Object that is in a WeakHashMap is bad practice, you prevent GC and have to manage cleanup. Use UUID, you don;t prevent GC, you don;t have ANY cleanup to do. You respect the contract

[flint coyote]

How do I not have any cleanup when I store a UUID in a hashmap/list/whatever? How else would it get removed?

that just keeps uuids laying around that are then checked in loops or whatever the list/map is used for

[eternal oxide]

UUID is persistent, Player is not

[flint coyote]

I know but you have to wipe it anyway

[eternal oxide]

what you do with yoru UUID storage is upto you, but using UUIDs will not break GC in Bukkit

Holding Players means you MUST cleanup or you prevent Bukkit properly releasing that Player and nstp GC on it

[flint coyote]

Cleaning it up on disconnect (which you have to do anyway) will not break it either

or should do

[eternal oxide]

You really are not understanding

In Bukkit Players are stored in a WeakHashmap. They do so for a reason. When a Player object is dropped it's free for GC to clean it up, without any outside inteference.
You holding a Player reference breaks that cleanup.

[flint coyote]

Well it's only dropped on disconnect

[eternal night]

Keeping an entity reference across tick is a pretty meh practice

[flint coyote]

if they start to change player objects in between ticks a lot of things will break

[eternal oxide]

When it's dropped makes no difference, Holding a reference is bad practice

[eternal night]

Doesn't mean you have to abuse it xD

[eternal oxide]

reference by UUD and you'll never have an issue

[eternal night]

already doesn't work for any other entity with chunk unloading etc

giving player instances special treatment because the server happens to maintain a single player instance for you

is a bit meh

[hybrid spoke]

you should always clean up your resources no matter in what context

[eternal oxide]

True

[flint coyote]

ugh fine I'll adapt it.
I hope there's a UUID to Player map and it's not some weird loop in the back to determine the player based on UUID.

[eternal night]

yea its backed by a map

[hybrid spoke]

just cast player to humanentity and tada

problem solved

[eternal night]

plain hashmap impl I think

concerning that java's uuid only shift some bits for their hashcode , that should be pretty fast if it doesn't collide too much

[river oracle]

Legacy versions just need to be dropped at this point

[eternal night]

I really hope whenever material registry stuff drops it does at least break some old things xD

just so people update

[vocal cloud]

inb4 someone brings up 1.8 combat

[river oracle]

Same here

[dire marsh]

when new combat snapshot, jeb?

[river oracle]

The current combat isn't bad tbh lol

I didn't like it at first but I've warmed up to it

[dire marsh]

I like both, and pretty good at both, but generally lean towards 1.9 combat because clicking just hurts after a while. (referring to 1.8 v 1.9)

[eternal night]

I did like his combat snapshots tho

the "hold down to spam" thing

was kinda nice

[dire marsh]

I believe that got some hate because it was too lenient in its timing

[eternal night]

I mean, everything in regards to combat is gonna get hate xD

[hybrid spoke]

pvp scene is toxic anyways

they will always find something to hate

[eternal oxide]

I like being able to rapid click (1.8) but I'm not willing to lose API functionality to keep it.

I don;t PVP but I do panic click when mobbed

[hybrid spoke]

how does a pensioner rapid click

[pseudo hazel]

I think its a different discussion with pve compared to pvp

[eternal oxide]

The problem is not how do we rapid click, it's how do we stop once we start.

[hybrid spoke]

when the parkinsonian kicks in

[eternal oxide]

exactly. very common behavior in the elderly

[hybrid spoke]

gets banned for autoclicker

[vocal cloud]

Honestly, when people started making guides on how to add tape to your mouse to click faster I think 1.8 PvP fell off https://www.youtube.com/watch?v=AWDBDZp3Y14

[hybrid spoke]

oh yeah and all the clicking techniques

butterfly, jitter, mouse abuse

and so on

[dire marsh]

These days it's a lot of: "where do you draw the line at cheating"

[agile anvil]

You have to show who has the biggest (click)

[eternal oxide]

My view it's cheating when you spawn items instead of earning, or you use ANY assistance when competing against others.

[dire marsh]

ANY assistance
rip all those fancy mouses

[eternal oxide]

if its just PVE there is no competition so anything goes

[hybrid spoke]

rip my double click mouse

[hybrid spoke]

dont say that

if i want to play survival its like 10 mins farming wood

then cheating some diamonds

[eternal oxide]

Thats fine

[hybrid spoke]

prebuilding my house in creative to have a better start

and never find a stop

[eternal oxide]

You are only cheating yourself out of enjoyment

you may as well have a play end credits button 🙂

[lyric turtle]

Hi, im using ProtocolLib, i want to clear nodes in ClientboundCommandsPacket, problem is that there is nothing like getNodes method in PacketContainer, what can i do about that?? is there any work-around??? maybe there is easy way that i dont see. problem is that there is no ProtocolLib's discord server or anything so i cant ask them.

[eternal oxide]

why are you messing with packets for commands?

[lyric turtle]

i have just made my own implementation of command system but on lower level, i was using packetevents for that but now i want to do that with ProtocolLib

[eternal oxide]

Not really anything to do with Spigot then

[lyric turtle]

hmm so where should i even ask?? like there is no ProtocolLib's discord server or anything

[echo basalt]

prolly this

nvm its not

[eternal night]

Concerning that that packet exposed brigadier types I'd be surprised if pl has abstractions for it

Unless it reimplemented those types or exposes brigadier

[lyric turtle]

i did wrapper for that in packetevents, its not that hard
https://github.com/retrooper/packetevents/blob/2.0/api/src/main/java/com/github/retrooper/packetevents/protocol/chat/Parsers.java

[livid dove]

Big truth.

Met a player who used an audio mod to use the raw coordinates data of the blocks producing ambient sounds, and fhen slipping an ambient sound in to gold ore blocks.

How was the sweat caught? Cause he Mined 9k Ore I 3 days lmao

[lyric turtle]

but if they wont do that, i still want to be able to modify this packet here, is there any work-around? can i somehow still get nodes list and modify it???

i was trying to use getModifier() but still i cant figure out

[vital ridge]

I'm trying to create custom persistentdatacontainer and then store it in my custom spawner. But I get an error at a serialization method in my custom persistent datatype class.
Error: https://paste.md-5.net/oxekubejey.cs

And that is my class: https://paste.md-5.net/mimawanono.cpp

[quaint mantle]

i have this on the top of my command

File crateLocationFile = new File(main.getDataFolder(), "locations.yml");
        YamlConfiguration locationFile = YamlConfiguration.loadConfiguration(crateLocationFile);
        ConfigurationSection locations = locationFile.getConfigurationSection("locations");

and when i try do this later on

ConfigurationSection crateEntry = locations.createSection(args[1]);

it says

Cannot invoke "org.bukkit.configuration.ConfigurationSection.createSection(String)" because "locations" is null

[eternal oxide]

you have to set to place a section, and it can't be empty

[quaint mantle]

what

i have to set to place a section?

[eternal oxide]

you have no locations section

[quaint mantle]

i do

[eternal oxide]

not in the file you are reading

[quaint mantle]

...

[eternal oxide]

that section is empty, it will do nothing

[quaint mantle]

its still a section?

[eternal oxide]

it will return null

[quaint mantle]

so what do i do to it to make my code work

how do i make it not return null

[eternal oxide]

if locations == null then set

when you want to add a location

is it a list?

[quaint mantle]

thanks

no

it stores coordinates

[eternal oxide]

in what?

a list?

a map?

[quaint mantle]

string

so like this @eternal oxide

if (locations == null) {
ConfigurationSection crateEntry = locations.createSection(args[1]);
crateEntry.set(args[1], targetCrate.getLocation().getX() + "," + targetCrate.getLocation().getY() + "," + targetCrate.getLocation().getZ());
}

or what

[fluid river]

what's this lol

[eternal oxide]

no

creATE YOUR SETRING, THEN CONFIG.SET(LOCATIONS", STRING)

err caps

I'm not retyping it

[quaint mantle]

ok

[quaint mantle]

GM BRO 🙂
can u help me for idea ?
if u help: i wanna give cooldown to cow milking
and i think this: when players right click the cow with bucket i added cows to hashmap key and i add unix time to data and
i control with if like this if(unixtime > cowtime ++ 30k) do somehing; else(cancel event;

is this good idea ?

[vocal cloud]

Don't cow's have PDC? You could just read/write from the PDC and it'd give it a level of persistence as well

[quaint mantle]

oh this good idea PDC is like uuid ?

[candid plover]

Can someone help me? I put reloadConfig but my configuration is not saved, just in case I restart the server

[flint coyote]

Reload does not save it

reload would re-read it if you changed it manually

you have to call save

[candid plover]

How do I save the configuration so that it updates in-game?

[flint coyote]

wdym by updates in game?

You change it on the file system by hand and then want the changes to be effective in game?

[candid plover]

For example, I changed the name of the item in the configuration, but it receives the old

[candid plover]

yes

[flint coyote]

in that case reload should be fine since you did the saving manually

[candid plover]

reloadConfig()?

[flint coyote]

yes

[candid plover]

does not work.

😭

 try {
      MainKits.getPlugin().reloadConfig();
      sender.sendMessage("§aConfigurações reiniciadas com sucesso.");
    } catch (Exception error) {
      sender.sendMessage("§cOcorreu um erro ao reiniciar as configurações.");
    }```

[vocal cloud]

The config you're writing to is the getConfig()?

[flint coyote]

I noticed that my reload method looks like this:

private FileConfiguration cfg;
//.....
public void reload() {
        plugin.reloadConfig();
        cfg = plugin.getConfig();
    }

I'm not sure if it is required. You can however try to do the same and see if that changes anything

[candid plover]

Configuration config = MainKits.getPlugin().getConfig();

[eternal oxide]

you have to update your config reference if you reload it

[flint coyote]

in that case it is actually required :)

[eternal oxide]

or stop storing your config in a temp variable and access it directly with getConfig()

[candid plover]

ohh, ok

I am going to try, thanks.

[fierce salmon]

Whenever I try and clear everything from my custom config file, it just reappears. How can I fix this?

nvm i figured it out

I just need to disable my plugin to be able to edit it

[rare ether]

anyone got the dependency for FastAsyncWorldEdit?

[tawdry echo]

https://intellectualsites.github.io/fastasyncworldedit-documentation/api/api-usage.html

[wise mesa]

random generation is working

i mean idk i haven't actually made it randomly generate

it just makes little squares that pretend to be rooms

to visualize

now i gotta port the code over

but that'll be easy

sometimes it doesn't work thouhg and idk why

oh well

[fierce salmon]

I am trying to make my plugin tell the player how long it takes them to complete the parkour. After completing the parkour, instead of giving me a normal number, it gave me 1.685975912549001E12 for some reason. Here is my code: https://paste.md-5.net/ucupeceyef.cs

[eternal oxide]

your timing is in milliseconds

[fierce salmon]

but like

why is it displaying that many milliseconds

Like i dont want 12 digits

[eternal oxide]

convert it to minutes and seconds

[fierce salmon]

the parkour takes 8 seconds to do

so the milliseconds should be 8000

and I divide it by 1000 to make it 8

but it still shows as a huge number

[warm mica]

Possibly because you never set a start time

Current time millis is 1685976882702

and you should store/get them as long and not as double

[fierce salmon]

oh ok

[fierce salmon]

No but I am trying to get a decimal point for the time in seconds

[eternal oxide]

there is no decimal point in these values

you are talking about formatting the display of the result

[warm mica]

in that case you'd cast it into a double after you calculated the difference as you only need it to be a double at that point

[fierce salmon]

ok

so when grabbing the values of parkourstarttime and parkourendtime, what variable type would i grab?

[warm mica]

Note that your server will heavily lag because of that plugin, there is likely no need to store these values within a config file

and to save/reload it each time

[fierce salmon]

should I just store it in HashMaps?

[warm mica]

Yes, unless you actually need that information permanently

[fierce salmon]

Only some of it I need permanently

[warm mica]

Then only store that permanently. And try to reduce the usage of config.save(), that can heavily decrease your TPS. One option would be e.g. an async scheduler that stores it each minute or something

and config.reload() shouldn't be used at all there, you already have everything loaded

[fierce salmon]

ok ty

[river oracle]

What would be the best way to go about a event happening 24 hours in the future. Should I just have a sync timer running and checking the time every tick?

[eternal oxide]

use a scheduledExecutor

[river oracle]

Can you send docs I don't think I've ever used one, sorry I'm on phone now just thinking of design lol

[mortal hare]

man clion's warnings are so sometimes annoying

Clang-Tidy: Overloaded 'operator++' returns a non-constant object instead of a constant object type

i add const as a return type

Clang-Tidy: Return type 'const typename nonogram::Table<t_element>::Row::RowIterator<t_finalElement>' is 'const'-qualified at the top level, which may reduce code readability without improving const correctness

[eternal oxide]

egjava LocalDate nextDate = LocalDate.now().with(TemporalAdjusters.next(DayOfWeek.MONDAY)); Long midnight = LocalDateTime.now().until(nextDate.atStartOfDay(), ChronoUnit.MINUTES); ScheduledExecutorService scheduler = Executors.newScheduledThreadPool(1); scheduler.scheduleAtFixedRate(()-> { /* Code here */ }, midnight, TimeUnit.DAYS.toMinutes(7), TimeUnit.MINUTES);

[mortal hare]

like wtf you suppose for me to do

[eternal oxide]

that schedules to run every monday

[mortal hare]

i add rvalue modifier, it still complains

[river oracle]

Thanks

[river oracle]

This isn't like 1 task per thread right I could run like 20 or so schedulers right

[eternal oxide]

yes, just increase the pool

[river oracle]

Does spigot have a default pool I could use / is there one I could just use

[eternal oxide]

not a real world time one

its all based on ticks in Bukkit

[river oracle]

Hmmm well all I'd be doing is someone enters a command for my plugin and a task is scheduled for a day later

I'd assume bukkit would be fine

[eternal oxide]

what do you need to do 1 day later?

[river oracle]

It's a start of an event

It notifies a group of players and starts the event after a day

The code for starting the event would be similar for each group I'd ideally save the time stamps, save relevant data and restart the tasks on server restart

[mortal hare]

people say java is bunch of boiler plate, wait till they see cpp's boiler plate in order to implement an iterator method:

typename nonogram::Table<t_element>::Row::template RowIterator<t_finalElement> nonogram::Table<t_element>::Row::template RowIterator<t_finalElement>::operator++(int) const & {

}

[hazy parrot]

Til you can override increment

Also what ampersand after const means lol

[mortal hare]

it means that rvalues cannot use this

basically you increment lvalue
