[lyric gyro]

works! tysm

[signal grove]

bukkit vectors are dumb, why would they modify and return

spent a while trying to figure out an issue because the original vector was modified

i guess ill just call clone() on everything

[royal cypress]

I found the version that clip made and decompiled it, seems to be pretty straight forward. Are you limited to only string based placeholders? Also are the calls for placeholders thread safe? meaning if an API action is calling a database call it is done outside the main server thread? Or is that not possible?

[minor summit]

What thread the expansion is called on is the same as the plugin requiring the placeholder ran PlaceholderAPI.setPlaceholders on

And the thread safety of the setPlaceholders call depends on what the expansions do

[signal grove]

hmm. this is close, but im not sure 100%. When it's shot, i set the arrow to be 100 ticks old (should be long enough to damage the player, but it still doesn't). Teleporting it behind the player and shooting slowly, it hits me, while shooting fast passes through me. This implies that it is time based, but not based on ticksLived.

maybe i could spoof the projectile source to something else

or (everyone will hate this) have pre-spawned arrows take its place xD

i dont like either solution

[floral beacon]

hello there
does somebody know how to make TAB list empty ("broken") like this
https://prnt.sc/R4pFefC9Ooar

[floral beacon]

Any ideas how to cancel properly bungee's ServerConnectEvent event?

[minor summit]

just cancel it? the event is cancellable

[shell moon]

true

[floral beacon]

this is what i get when i cancel it

net.md_5.bungee.util.QuietException: A plugin cancelled ServerConnectEvent with no server or disconnect.

until timeout
[02:38:17 INFO]: [Test2] disconnected with: ReadTimeoutException : null

https://hastebin.com/exemejexat.php

i think i'm not doing anything special here, yet it just happens

[minor summit]

is this like an initial login connection? or server switching?

[floral beacon]

yes

initial

i just wanted to mention that like right while you were typing

[minor summit]

you should use the login event for that

[floral beacon]

but i need to check for specific server (target server)

[minor summit]

mm

[floral beacon]

how can i check the target server too

[minor summit]

i suppose you are meant to cancel the event and also disconnect the player (if you don't want them to join another server like a limbo or something)?

[floral beacon]

yes

maybe connection.disconnect(?)

i'll give it a try

works 😄

thanks @minor summit

[minor summit]

nice

[pure crater]

Just wondering, is there a gradle plugin that can clone repos from Github and build them into your local maven/gradle repo?

I tried using Grgit and making my own method in kts but i failed miserably

And no, I'm not using Jitpack 🤢

[dusty frost]

yeah so there's actually this concept called maven repositories who host compiled artifacts for people to use in their gradle builds so that they can utilize the api

it's a pretty cool system actually

[leaden sinew]

No! That doesn't exist!

[ashen lodge]

Basically, I made a custom mining system using packets. But if i mine with a pickaxe it will override and my canceling of block damage event doesnt work?

what shall i do

[pure crater]

if ur broke tho 😭

[dusty frost]

maven central

[leaden sinew]

Did you send a mining fatigue packet?

[ashen lodge]

yes

they have mining fatigue -1

should it be 1?

@EventHandler
    public void blockDamage(final BlockDamageEvent e) {
        e.getPlayer().addPotionEffect(new PotionEffect(PotionEffectType.SLOW_DIGGING, Integer.MAX_VALUE, -1, false, false), true);
        e.setCancelled(true);
    }```

[signal grove]

people arent allowed to break blocks at all?

[ashen lodge]

You talking to me?

[signal grove]

yes

[ashen lodge]

here ill make video

[signal grove]

just make sure that you also cancel a block break event. I'm not positive that cancelling all the damage events will stop a break event from happening with a laggy client

[ashen lodge]

https://gyazo.com/d258e0ff7d13a37cdc9136acc9350084

heres the problem

the pickaxe mining speed

is like faster that the speed i made

so they get a glitch where they "break the block" but its not supposed to be broken yet so they have to continue breaking again

[signal grove]

what do you want to happen

[ashen lodge]

look dms for videop

[signal grove]

yes i see, what is the intended behavior though

[ashen lodge]

Would you wish to see videos or anything? i think you know what its supposed to look like

[leaden sinew]

I’m pretty sure this doesn’t get called if you switch to another block after holding down the break button, or something like that happens

I’m not sure I understand your issue though

[edgy hearth]

how to get category name from path
example

PlayerLevels:
  3ffc17e8-e417-30ef-80ce-4f9b1da4f0f6:
    guilda:
      Test:
        name: test2
        dono: zThyPvpTK

how to get "test" category in yml
I tried

``` but it returns null value, help pls

[dark garnet]

Database or collection?

[dense drift]

I meant table, sorry, so if you are using mongo that would be a collection

[dark garnet]

guilda is not a string

[edgy hearth]

in this case the guild is just to get the value inside with getstring, in this case the Test value would not be a string, my question is what would it be? and how can i pull

[dusky wolf]

Any ideas on why that won't return anything?

    @Override
    public String onPlaceholderRequest(Player p, String identifier) {

        if (p == null) {
            return "";
        }
        // %townywild_cooldown%
        if (identifier.equals("cooldown")) {
            return plugin.getConfig().getString("protection_time_after_exiting_town_border", "Not protected");
        }```

```java
    PROTECTION_TIME_AFTER_EXITING_TOWN_BORDER(
            "protection_time_after_exiting_town_border",
            "20",
            "# This is the amount of time in seconds, the player exiting the town border will have PvP protection for, during that time, the player cannot hit or get hit by other players.")```
I have this in my ConfigNodes

[proud pebble]

your supposed to use onRequest afaik

not onPlaceholderRequest

[dense drift]

maybe player is null?

dont do null checks for player if you dont need a valid player

[proud pebble]

that could be true

[dusky wolf]

would that be right?

    @Override
    public String onPlaceholderRequest(Player player, @NotNull String identifier) {
        if (identifier.equals("cooldown")) {
            long remainingTime = Integer.parseInt(getConfig().getString("protection_time_after_exiting_town_border")) * 20L;
            return Long.toString(remainingTime);
        }
        return "";
    }
}```

[dusky wolf]

oh

protection_time_after_exiting_town_border is in ticks so it multiplies by 20 to get seconds

[sharp ibex]

is it possible and if how

[tight junco]

possible yes, how it entirely depends

most common way id think is a worldguard flag

but you could also define custom regions etc etc etc

[dusky wolf]

is there an easier way of doing a cooldown system?

    private HashMap<UUID, Long> scheduledRemovalTimes = new HashMap<>();

    public void scheduleRemoval(Player player, long time) {
        scheduledRemovalTimes.put(player.getUniqueId(), System.currentTimeMillis() + time);
    }

    public long getRemainingProtectionTime(Player player) {
        Long scheduledRemovalTime = scheduledRemovalTimes.get(player.getUniqueId());
        if (scheduledRemovalTime != null) {
            long remainingTime = (scheduledRemovalTime - System.currentTimeMillis()) / 1000;
            if (remainingTime > 0) {
                return remainingTime;
            }
        }
        return 0;
    }
.......................

    @Override
    public String onPlaceholderRequest(Player player, @NotNull String identifier) {
        if (identifier.equals("cooldown")) {
            return Long.toString(getRemainingProtectionTime(player));
        }
        return "";
    }
}```

this is what it looks like but it still doesn't seem to return anything

It takes it from a listener class I made before

    //create a map to store the scheduled removal time for each player
    private Map<UUID, Long> scheduledRemovalTime = new HashMap<>();

    @EventHandler
    public void on(PlayerExitsFromTownBorderEvent event) {
        UUID uuid = event.getPlayer().getUniqueId();
        protectedPlayers.add(event.getPlayer().getUniqueId());
        long scheduledRemovalTime = System.currentTimeMillis() + (Integer.parseInt(getConfig().getString("protection_time_after_exiting_town_border")) * 1000);
        scheduledRemovalTimes.put(uuid, scheduledRemovalTime);
        Bukkit.getScheduler().runTaskLater(plugin, new RemoveProtectedPlayerTask(uuid, protectedPlayers, scheduledRemovalTimes), Integer.parseInt(getConfig().getString("protection_time_after_exiting_town_border")) * 20L);```

[opal geyser]

Afaik, you can use PDC, adding a node like Cooldown: (EpoachTime)

Easier to get it and no need to worry on how to save on server shutdown.

[dusky wolf]

yeah but it isn't a cooldown for a command

basically when a player exits a town, his uuid is saved and he is protected from being attacked for a set amount of time

then after the timer, his uuid is deleted from the list

[opal geyser]

You can still use the PDC for it.
1 - you can have a task running to delete that from PDC. Though, here, y'd need to save which players still need to be checked due to server shutdowns.
2 - you said that the player is protected from being attacked for a set amount of time. You can check when the player get attacked and see if the "amout of time" have already passed. If so, remove the node from the PDC.

[dusky wolf]

Just a small question, what is PDC

it's my first plugin I'm doing so i'm still learning

Can someone tell me why this isn't working? There's no errors or anything but when i join the server it doesn't say anything

    Bukkit.getLogger().info("Player spawned at " + x + y + z);
}

}

[dense drift]

do you instantiate the class?

[cinder hare]

I don't know what that means

this is the first time i've ever tried doing anything with java/minecraft

[dense drift]

do you have new PlayerHandler(plugin); (or this instead of plugin) somewhere in your code?

[cinder hare]

uhh no

[dense drift]

ok, do that

[cinder hare]

where though

[dense drift]

in your onEnable method

[cinder hare]

oh

public final class BountyPlugin extends JavaPlugin {
@Override
public void onEnable() {
getLogger().info("Succesfully loaded");
new PlayerHandler(BountyPlugin);
}
}

It's giving me an error

[dense drift]

use this, not BountyPlugin.
this is an instance of the class where you use it - in this case, an instance of BountyPlugin - and BountyPlugin is a class.

[cinder hare]

thank you so much

[dense drift]

[shell moon]

If my plugin depends on adventure (which is available on paper only) but ofc i want it to work in spigot too

what would be the best way to do it?

[dusky harness]

would be so nice with kotlin extension functions 😌

[dusky harness]

If you have any features that you want to only work on paper, then the safest way would probably to have a spigot module and a paper module

besides that, you should just use spigot api and shade & relocate adventure

I think most, if not everything should still work if you use legacy serializer with hex and bungee component serializer (or you can use nms and gson serializer)

[shell moon]

i was thinking about the same, issue comes when new mc versions are released and adventure requires updates

additionally, the fact that not only 1 of my plugins will use it, but at least 3 (and probably more in the future)

[dusky harness]

besides the 1.19 chat update for example I don't think it should break each version

[shell moon]

maybe making a library (.jar) with adventure inside which can be updated when new versions of adventure appears without needing to shade it

and updating each plugin, would be a good idea?

[dusky harness]

yeah
they have the bukkit-platform which helps sending messages to players and console

wait what

I don't know about automatically updating adventure since it might have like breaking changes

[shell moon]

i mean, i doubt Component.of etc appendReplacements and other methods change in a future

probably internally, hence why updating just a .jar with the adventure inside

would be the better solution instead of updating every single plugin that has the library shaded

(saldy, making the plugin paper exclusive, is not an option, in case someone was going to say that)

[dusky harness]

is the plugin open source

a possibility is to setup github actions &/or repository-only bot to automatically update (the buildscript) and build the jar 💀

idk how easily slimjar/alternatives makes it easy to add custom libraries

might be really easy or hard

¯_(ツ)_/¯

[shell moon]

😮

i honestly have no idea how to do that tbh

i guess i'll just make a library .jar for now

until spigot shades adventure

[dusky harness]

so you know how to make library .jar? 🥲

[shell moon]

yeahhh, i think, at least maven and its relocation works for me :,v

[dusky harness]

🤔

ok

[shell moon]

[cinder hare]

nvm i found a solution

[ashen lodge]

Is it possible to change a block texture using a texturepack

[dark garnet]

i would hope so else they wouldnt rly be texturepacks 💀 (thats a yes)

[ashen lodge]

no

like some times its bedrock then some times it turns into redstone block

for say

didnt explain well

lol

@dark garnet

[dark garnet]

oh lmao i think u can use CustomModelData to achieve that but there might be an easier way
change the block's CustomModelData between 2 values and have resourcepack with those 2 values with the 2 textures

[ashen lodge]

do you know how i would do that?

[dusky wolf]

any idea for this?

        if (identifier.equals("countdown")) {
            return Long.toString(getRemainingProtectionTime((Player) player));```
this returns the seconds without anything, example: Protection time left: 5 (placeholder here)

But when I use this

    @Override
            public String onRequest(OfflinePlayer player, String identifier) {
                if (identifier.equals("countdown")) {
                    long remainingProtectionTime = getRemainingProtectionTime((Player) player);
                    long remainingProtectionTimeInSeconds = TimeUnit.MILLISECONDS.toSeconds(remainingProtectionTime);
                    if(remainingProtectionTimeInSeconds>60){
                        long remainingProtectionTimeInMinutes = TimeUnit.SECONDS.toMinutes(remainingProtectionTimeInSeconds);
                        return Long.toString(remainingProtectionTimeInMinutes) + " minutes";
                    }else{
                        return Long.toString(remainingProtectionTimeInSeconds) + " seconds";
                    }
                }
                return "";
            }
}```

It returns **0 seconds**

[dusty frost]

what are you asking

[dusky wolf]

I'm trying to make it countdown the placeholder

Basically I set up the protection time in the config file

protection_time_after_exiting_town_border: '20'```

But it only outputs 0 seconds instead of doing it like

20
19
18
...

[dusty frost]

okay so check if TimeUnit.MILLISECONDS.toSeconds(remainingProtectionTime); is what you think it is

just have it return that first

[dusky wolf]

https://imgur.com/a/b9DamfW

    @Override
    public String onRequest(OfflinePlayer player, String identifier) {
        if (identifier.equals("countdown")) {
            long remainingProtectionTime = getRemainingProtectionTime((Player) player);
            long remainingProtectionTimeInSeconds = getRemainingProtectionTime((Player) player);
            if (remainingProtectionTimeInSeconds > 60) {
                long remainingProtectionTimeInMinutes = TimeUnit.SECONDS.toMinutes(remainingProtectionTimeInSeconds);
                return Long.toString(remainingProtectionTimeInMinutes) + " minutes";
            } else {
                return Long.toString(remainingProtectionTimeInSeconds) + " seconds";
            }
            }
            return "";
        }
}```

this doesn't return 0

but the bossbar gets stuck for some reason

        public void startProgressUpdater() {
        progressUpdaterTask = Bukkit.getScheduler().runTaskTimer(this.plugin, new Runnable() {
                @Override
                public void run() {
                    Long scheduledRemovalTime = scheduledRemovalTimes.get(uuid);
                    if (scheduledRemovalTime == null) {
                        return;
                    }
                    long remainingTime = scheduledRemovalTime - System.currentTimeMillis();
                    if (remainingTime <= 0) {
                        run();
                        return;
                    }
                    BossBar bossBar = bossBars.get(uuid);
                    if (bossBar == null) {
                        return;
                    }
                    double totalProtectionTime = Integer.parseInt(Objects.requireNonNull(getConfig().getString("protection_time_after_exiting_town_border"))) * 1000L;
                    double progress = remainingTime / totalProtectionTime;
                    bossBar.setTitle(PlaceholderAPI.setPlaceholders(getPlayer(),bossBarText.replace("%townywild_countdown%", String.valueOf(remainingTime))));
                    bossBar.setProgress(progress);
                }
            }, 0L, 20L);
        }```

maybe my bossbar progress updater is wrong

[grim oasis]

y'all is it possible to find which .jar a plugin is coming from/loading from?

@true mountain has a plugin Custom Enchants that is loading and no idea where from

no .jar exists in the plugin directory

gah

we found it

any ideas?

[river solstice]

I haven't tested it but,

for (Player player : Bukkit.getOnlinePlayers()) {

maybe?

[tired olive]

A serialization stream header is read from the stream and verified.
From the jd
2
im guessing the file is empty and its trying to read the headdr

[river solstice]

well it's definitely not empty

even if I save default value before reading, I get the exception

[sterile hinge]

Don’t use the old file api, don’t close streams manually (use try-with-resources), probably don’t use java serialization

[icy shadow]

https://tenor.com/view/1984-gif-19260546

even better

[shell moon]

if my plugin needs to be configurable with custom GMT (yes, for date)
how would i make it exactly? was thinking about getting current machine time and then modify it to match specified GMT, any ideas?

[river solstice]

well, I found the issue.
and I'm not using this type of serialization for very important stuff

so I don't mind using it

just need some things to persist through restarts is all

[dense drift]

There's ZonedDateTime if you want to get the time at a certain time zone https://docs.oracle.com/javase/8/docs/api/java/time/ZonedDateTime.html @shell moon

[shell moon]

mmmm if i want owners to be able to set
Local-gmt: "-5" (for example, for my country)

so they dont need to worry about machine time in dedicated/hosting

[dense drift]

You can do that, but id recomment to allow them to write any type of time zone, e.g. Europe/Bucharest for Romania instead of GMT+2 and GMT+3 for summer time

[shell moon]

issue is that people might make errors when editing that

in my case (iirc) is Bogota/Lima for GMT -5

but many people dont know what to write there

so if they fail, system will fail too right?

[dense drift]

Google exists

[shell moon]

You know how people is

I wanna make it for spigotmc

and ppl in spigotmc is kinda

[dense drift]

https://mkyong.com/java8/java-display-all-zoneid-and-its-utc-offset/

is just a time zone, is not a big deal

put this link in config and tell them to look for Continent/Capital or City or whatever that's relevant to their local time

and if they enter an invalid value, just fallback to the time of the machine

[minor summit]

for ZonedDateTime (more specifically ZoneId/ZoneOffset) you can input both Continent/City and GMT±n

[dense drift]

yup, exactly

[spiral prairie]

Why exactly are people still using DeluxeMenus?

[broken elbow]

Why wouldn't they?

[dense drift]

wrong channel also

[spiral prairie]

Are there any special features? Cause I'm currently searching for a good menu plugin to use xD

[dense drift]

whether a plugin is good "good" depends on your needs

[proud pebble]

tbh i very much enjoyed using deluxemenus, it has very good documentation

[spiral prairie]

that's why I'm asking?

I'll try it out, thank you

[cinder hare]

I'm trying to activate a loop inside of a switch case without stopping the switch case, does java have coroutines or something that can help me do this?

[shell moon]

Best way to make it players cannot only play for 1 hour and reset it at 00:00?

so if they play from 21:00 they are kicked at 22:00

[stuck hearth]

Schedule a task

[shell moon]

but if they play at 23:30, they are not kicked at 00:00 but at 01:00

sync or async?

one per player or for the server to constantly check seconds left?

[stuck hearth]

I would probably have a global task. Probably synchronous

[shell moon]

so basically a timer with interval 20L

[fiery pollen]

For MySQL databases, would it be better to update the data every time there is a change to the value or only update it every 30s?

[minor summit]

on every change is fine, just make sure you run the queries off the server thread

[cunning geyser]

Would anyone happen to know about paginated guis using triumphguis (mf-gui)

[dusty frost]

A. Do you actually have 2 pages of things in it? It only generates the minimum number of pages and B. Did you setup both click listeners?

[cunning geyser]

I haven’t made 2 pages, i’m not sure how

[dusty frost]

you have to add items to it

                p.sendMessage(lores);
                }
            }
        }
    }
```  (when i first click on the item with the lore test123, it works and sends me the lores, but after i click it back to another slot, a stack trace pops up and i have no idea whats causing it)

using InventoryClickEvent fyi

[dusky harness]

in the future please paste the stacktrace
but in this case, IntelliJ at least should be giving a warning that getItemMeta is nullable
just like how you nullcheck item, you have to do the same for the meta (as it's null for air)

[unborn ivy]

my bad

[unborn ivy]

i use eclipse not intellij

ill put the stack on pastebin

[dusky harness]

nonono its ok

[unborn ivy]

https://pastebin.com/qf4wMiuY

[dusky harness]

barry did it for you

[dusky harness]

in here

[unborn ivy]

oh ok

[dusky harness]

but yeah as I suspected, it's a NullPointerException - likely due to the item meta

[unborn ivy]

wait so i need to check if the itemmeta is null aswell?

[dusky harness]

yep
it's null for air

idk if there are others

[unborn ivy]

wait

but if i already checked that the item is null

why do i still need to check for the itemmeta

[dusky harness]

ItemStacks can be air
however, ItemMetas cannot be air bc itemmeta stores stuff like lore, etc which air cannot have

[unborn ivy]

in my code im just checking if the item isnt an empty space, and if it has lore itemmeta

[unborn ivy]

i broadcasted e.getCursor()

on the first click it says that the itemstack is air

and when i put them item back it shows me my item with its meta

[dusky harness]

the item is not null; the meta is

the meta is not the item

technically multiple items can have the same itemmeta

I wouldn't recommend it but it's possible

you have to check if the itemmeta is null

[unborn ivy]

i was just debugging

        if (item != null && item.getItemMeta() == null) {
            p.sendMessage("test");
            return;

"test" seems to always send

even if the item has itemmeta

or no meta

https://i.gyazo.com/85f9f43fcc12d04788789b5c5f826f5c.png

[dusky harness]

show full code

🤔

[unborn ivy]

        Player p = (Player) e.getWhoClicked();
        ItemStack item = e.getCurrentItem();
        p.sendMessage("" + e.getCursor());
        if (item != null && item.getItemMeta() == null) {
            p.sendMessage("test");
            return;
``` this is what i have rn, i have commented out the other code

[dusky harness]

        ItemStack item = e.getCurrentItem();
        if (item != null && item.getItemMeta() != null && item.getItemMeta().hasLore()) {
            String lore = item.getItemMeta().getLore().get(0);
            if (ChatColor.stripColor(lore).equals("test123")) {
                for (String lores : item.getItemMeta().getLore()) {
                p.sendMessage(lores);
                }
            }
        }
    }
```this should work btw

[unborn ivy]

thats what you meant by checking if its null... i was gonna check if it had lores with !item.getItemMeta().hasLore()

[dusky harness]

getCursor and getCurrentItem are different

the sendMessage you're doing getCursor

but item is getCurrentItem

iirc getCursor is what was previously selected on your mouse/cursor, and getCurrentItem is what was previously in the slot

I might have it mixed up though

🥲

[unborn ivy]

i figured

minecraft is weird

thanks for the help

[dusky harness]

yeah I don't remember exactly what it is but I can tell you 100% that they are different

[dusky harness]

np

[dusky harness]

spigot*

🙃

[hoary scarab]

Pretty sure getItemMeta() doesn't return null because it's suppose to create it if it is.

[dusky harness]

for air it returns null

wow

bad @uneven lantern

[hoary scarab]

Ah. Isn't there hasItemMeta()?

[dusky harness]

I think so

I assume it does the same thing though like hasLore

[hoary scarab]

👍

[proud pebble]

HasItemMeta() checks if it has meta in general, hasLore is specifically if it has lore or not, so i wouldnt call it the same thing

but if it doesnt have meta, then it doesnt have lore

[dusky harness]

I mean like how the method works

they both check for null and in lore's case it checks if the lore is not empty and for meta it pretty much just checks if the meta is null or not

not exactly related but apparently for air, the nms item is null 🤔

I wonder how air looks like in internal minecraft code then (and if an air type exists in internal minecraft code? 🤷)

[proud pebble]

afaik air original was id 0

in most instances the itemstack is still AIR

even in nms

[proud pebble]

there is actually multiple versions of air

oop double ping

AIR,CAVE_AIR and VOID_AIR

[minor summit]

the internal inventory lists are specifically lists that disallow null elements, bukkit literally transforms air nms itemstacks into null bukkit itemstacks, it's so fucking stupid

[tired olive]

Im 0% sure but i think theyre different
https://wiki.vg/Slot_Data
Here null would mean present is false and material.air would mean air item id but honestly idk that could just be for the protoxol

[minor summit]

Yeah wiki.vg doesn't really represent how the game is actually structured, they only show you the raw byte streams for the packets when sent through the wire
Which doesn't even represent the packet Java classes structure but many people using ProtocolLib think they do and then wonder why some things don't work when "wiki.vg says this but ProtocolLib says that"

[proud pebble]

from my own testing virtual inventorys their slots that are empty are null, but with actual inventorys their slots that are empty are air.

[minor summit]

virtual and actual?

what

[broken elbow]

just like money

Virtually, they're like air, actually, they're missing

[minor summit]

vanilla/internals/nms does not use null for empty slots, it uses a NonNullList and it uses a constant ItemStack.EMPTY (air) item for empty slots
bukkit is the one that uses nulls for bukkit inventories most of the time, there are places where it actually uses air items which makes things even more confusing
the serialised packets use a boolean flag for empty/non-empty because writing an entire item stack for empty slots would be extremely wasteful

[worn jasper]

Is it possible to know which plugin logged something in the console? (if it didn't use it's own logger, but the server's logger)

[proud pebble]

virtual inventories that are created through bukkit.createinventory have null slots, inventories that are created from a opening it using a block have AIR itemstacks in their slots, so you are correct, bukkit is the reason slots can be null

[dusky harness]

btw
if bukkit made a copy of a bunch of things in nms, wouldn't it increase the memory usage by a whole bunch?

although I think the majority just calls to nms, but for things like inventories - would it increase the memory usage by a noticeable amount?

or are there too little cases where bukkit copies stuff that it doesn't impact memory by much

[minor summit]

yes

ok

[broken eagle]

its a web host dude

how can the ram get broken

oh my god

well that's why it isn't working lmao

you just said it

how can i parse 1y1mo1w1d1h1m1s into a long representing milliseconds

just gonna quickly ask chatgpt actually

chatgpt gave me a huge regex thing for it and then gave up at the end, it's last word was It's on a new line lmao

yoiiiiiiink

[dusky harness]

there's also piggy's timeapi

but luckperms >

[pulsar ferry]

Just copy Kotlin's Duration

[proud pebble]

imma suggest you use M instead of mo

like if your wanting to go down that path

[dark garnet]

has to be mo, this is for a discord bot and 99% of bots use mo

[proud pebble]

ic

[dusky harness]

m conflicts with minutes

[dusty frost]

capital M

[spiral prairie]

regex

[icy shadow]

wow so helpful

[shell moon]

Looks good, allowed to copy in our plugins?

[proud pebble]

my thoughts when i said that was by using single characters to find the unit, which M and m are different characters technically. wouldve thought it was faster or something to do exactly that

[stuck hearth]

Mit license

[shell moon]

that means? xd

[supple oar]

it means yes but if it makes ur pc blow up u cant sue them iirc

[shell moon]

[dusky harness]

u gotta copy and paste the header

thats it

[supple oar]

u dont even need a header it can be anywhere

[dusky harness]

wdym?
iirc it either has to be in like the project root or in the header

 *  The above copyright notice and this permission notice shall be included in all
 *  copies or substantial portions of the Software.

I might not be right tho idk 🤷

[shell moon]

what?

[supple oar]

just put the mit license in like a LICENSE file, hope it doesnt blow up ur pc and ull be good

[dusky harness]

ye

[shell moon]

what's that

xD

you mean the comments?

[supple oar]

a file

called LICENSE

[dusky harness]

https://github.com/LuckPerms/LuckPerms/blob/master/LICENSE.txt

[supple oar]

look up "MIT license" and paste it into that file

[dusky harness]

I'd assume you paste that in there

[supple oar]

ye

[dusky harness]

although shouldn't you put it as a header too?
so that it's known which files are taken from luckperms

I don't remember what projects do

[supple oar]

doesnt rly matter, both work

[dusky harness]

oh ok

[shell moon]

ahhhhh

too complicated

:,v

[dusky harness]

either just copy and paste https://github.com/LuckPerms/LuckPerms/blob/master/common/src/main/java/me/lucko/luckperms/common/util/DurationParser.java without the package line and I think you should be fine
Twisty mentioned putting the license file in the root project which I bet is probably also recommended but idk how the naming for that goes or anything

feel free to google it

or ask chatgpt

¯_(ツ)_/¯

[shell moon]

xD

[minor summit]

or a lawyer

ideally

[supple oar]

shouldnt matter tho if ur taking 1 file

lucko or whoever will just ask u to change it at worst

its too much effort to cry over it

and costs them money if they wanna cry and sue or smth and probably not win

it is posible progressbar in voteparty plugin?

[river solstice]

would be a good idea to add multiple-channel copy-paste protection to @neat pier

anyone know how to damage a player without affecting their velocity? I calculate what their velocity is supposed to be separately and set it, but the damaging sends them off randomly. https://paste.helpch.at/heyugejoso.java

[hazy summit]

Hey, Im trying to integrate vault into my plugin. This is what I tried so far: https://paste.md-5.net/uweyizurum.java

but the RegisteredServiceProvider is always null, so then I tried the ServiceRegisterEvent: https://paste.md-5.net/vipubafeda.cs

but the event is never called, even though I made sure to register it in the onEnable() method. Can anybody help me?

[dusky harness]

You're not shading vault, right?
And make sure u have it as depend

Or softdepend

[hazy summit]

I added the api to my pom like the github page says https://github.com/MilkBowl/VaultAPI

And I already set Vault as a depend in my plugin.yml

[river solstice]

well, do you have the classes that vault provides?

ex. net.milkbowl.vault.economy.Economy

[hazy summit]

yes, I can access that

[river solstice]

hm, that's weird. where do you call the setupEconomy?

[hazy summit]

I call it onEnable(), after initializing the plugins' files and registering commands

@Override
public void onEnable() {
  instance = this;

  FileManager.loadFiles();
  CommandManager.register();

  EconomyManager.setupEconomy();
}

for the event, I just implement Listener into the EconomyManager and replace the EconomyManager.setupEconomy(); with getServer().getPluginManager().registerEvents(new EconomyManager(), this);

[river solstice]

well, could you try making it non-static and moving the method from EconomyManager class to your main one?

[hazy summit]

https://paste.md-5.net/qomegaporu.java
the RegisteredServiceProvider is null

[river solstice]

could you paste the full class, with imports and what-not?

[hazy summit]

yea sure one second

[hazy summit]

https://paste.md-5.net/letibosuxu.java
Full Main class

[river solstice]

well, everything seems to be correct

are you sure vault is installed on the server?

[hazy summit]

https://imgur.com/a/zSKsuQT yes

its enabling and everything, only thing not working is my plugin

https://paste.md-5.net/ujagiqeniy.md my log

Maybe it would work if I had actually added an Economy plugin 🤦‍♂️

[river solstice]

true

[dusky harness]

¯_(ツ)_/¯

[proud pebble]

ah yes, that might help just a tad

[floral beacon]

is BukkitRunnable() looping over and over until it reaches cancel()?

[river solstice]

Basically, yes.

Or your plugin gets disabled

[floral beacon]

what can i use that is like BukkitRunnable() but to execute only once?

[river solstice]

Bukkit.getScheduler().runTask

Or .runTaskAsynchronously

Or .runTaskLater

[floral beacon]

thanks a lot

[river solstice]

Might not be the exact syntax, but use Bukkit.getScheduler instead of BukkitRunnable itself

[floral beacon]

That is recommended?

[dusky harness]

BukkitRunnable#runTask

it doesn't always loop

only if you do runTaskTimer or runTaskTimerAsynchronously

[floral beacon]

thanks

also related to this
how can i delay the first iteration?

[dusky harness]

yes

look into runTaskLater

runTask delays it by 1 tick

runTaskLater lets you cutomize it

same with runTaskTimer, etc

[floral beacon]

i want to do something on player join (talking about bukkit/spigot plugin)
how can i delay the task, but to delay it in such way that the first iteration that is ever done within that code will be delayed, so like

• player joins
• wait x ticks
• do first iteration/whatever
• ...

❌ not like:

• player joins
• do first iteration/whatever
• wait x ticks

i see that it has delay

but how to make delay apply for first iteration ever

ok finally

it worked with runTaskLater

thanks a lot @dusky harness

[dusky harness]

yes, runTaskTimer allows for that

it has 2 parameters

1 for the initial delay, then another for the delays after

[tight junco]

you're looking for taskLater

taskTimer is repeating

[floral beacon]

thanks

what's the best idea to remove all potion effects for the player (i want to do this on join)

should i first get user effects then loop and remove each or is there a way to remove them all at once (something like Player#clearEffects())

[tight junco]

there isnt a clear effects function from what I can see

probably just getActivePotionEffects forEach removePotionEffect

[dusky harness]

he wants to repeat I think
since he mentioned "first iteration"

but if it's not repeat then yeah tasklater works

[dusky wolf]

    @EventHandler
    public void on(PlayerEntersIntoTownBorderEvent event) {
        UUID uuid = event.getPlayer().getUniqueId();
        System.out.println("Player just entered the town border");
        if (protectedPlayers.contains(uuid)) {
            protectedPlayers.remove(uuid);
            System.out.println("player protection ended");
            Long scheduledRemovalTime = scheduledRemovalTimes.get(uuid);
            if (scheduledRemovalTime == 0) {
                return;
            }
            scheduledRemovalTimes.remove(uuid);
            if (bossBars.containsKey(uuid)) {
                BossBar existingBossBar = bossBars.get(uuid);
                existingBossBar.removeAll();
                bossBars.remove(uuid);
                // stop the running task if it exists
                if (bossBarTasks.containsKey(uuid)) {
                    Bukkit.getScheduler().cancelTask(bossBarTasks.get(uuid));
                    bossBarTasks.remove(uuid);
                }
            }
        }
    }```

The bossbar should actually be cancelled and not count the 5 seconds I spent inside my town then remove the bossbar when it says I have 10 seconds of protection left but I wonder if it's something to do with the HashMap for bossBars

Here is the whole class: https://paste.learnspigot.com/uhuhadacog.java (sorry for the bad code, it's my first plugin)

        if(item == null) return;
        e.getPlayer().sendMessage("Start!");

        }
    }

I want to get the value by the key.

[graceful juniper]

How did you test this? What is the current outcome with that code?

there isnt an "extra" field in what serialize returns

[signal grove]

Hey! This isn't solving your problem but the first thing you should do is come up with new names for your methods (right now, they are all called "on"). For example, your PlayerEntersIntoTownBorderEvent handler should be named something like "onPlayerEntersTown" or something similar, rather than just "on".

unless it's some convention ive not seen before

[broken elbow]

In your CMD execute java --version. What does it return?

When have you installed java? Was it today and it broke right after installation or did it work before?

If it broke after working before, any chance you messed with the environment variables?

I guess that is also a way to fix it. I was thinking you probably just need to edit an environment variable to fix it.

Well JAVA_HOME and PATH I guess.

Did reinstalling not fix it?

[bitter flint]

what handling event keyPressed in plugin java 11?

[broken elbow]

In your PATH variable, are you sure there is a path pointing towards your java.exe?

No, as in you're not sure?

[bitter flint]

Blitz help me pleasse

[broken elbow]

It won't actually end with java.exe. It is just going to point to the parent directory.

[broken elbow]

I'm afraid I do not know the answer

[bitter flint]

Shit...

[broken elbow]

Oh do not worry. I was brain dead long before I met you.

Can you open the PATH variable and send a screenshot from there?

No. That's not what I meant

There's a variable called Path

you can see it in the screenshot

Where did you install java? Is it C:/Program Files/Java/jdk-19/ ?

Then double click on Path (environment variables), click New and in the new filed it creates, type C:\Program Files\Java\jdk-19\bin

[minor summit]

after changing the path you need to close the open terminal/cmd line and open a new one

well maybe you don't

i don't know if you do or don't know

what are you running? powershell? that's the default on win11 i belive

[broken elbow]

Can you check both the user variables and the system variables? They both will probably have a variable PATH. Send a screenshot from both.

[river solstice]

is there a better way to store data instead of using a List if I only need to store exactly 2 values?

[dusky harness]

Map.Entry

Map.entry()

[dusky harness]

i dont think this method exists in java 8 though

so you'd have to make your own Pair class

or preferably a data class

the best way would be a data class

[sterile hinge]

java 8 💀

[dusky harness]

even for 2 values it's probably best

[river solstice]

yeah I don't use outdated software, no worries

[dusty frost]

The IP address, the server it's trying to connect to. Are you hosting it on Docker? It's very unlikely the ip is 127.18.0.1

I've been working on a custom block breaking speed implementation (what a mouthful) and it works completely fine, but one thing.
Usually after the client breaks a block, there is (unless instantly broken) a 6 tick delay before you can start mining the next block;
However with my implementation the server is the one breaking the block using Block.breakNaturally, which means the client does not get the intended delay and can immediately start breaking the next custom block.
My current workaround is setting the player to Adventure Mode for 6 ticks and setting them back to Survival Mode, which... works, but doesn't feel right at all;

Is there a packet or something I've missed that let's me tell the client they've broken a block to trigger the delay?
If there isn't and someone has a better idea, I'd appreciate it!

[leaden sinew]

I’m assuming you’re using mining fatigue, if you are then just don’t add progress to the block during the 6 ticks

[inland meadow]

I am using mining fatigue yes;
since I am trying to make it look as convincing as possible; the issue is that the client still hears the mining sound if I was to just block the progress

[static jewel]

is PlaceholderExpansion#canRegister() called before or after Configurable#getDefaults()? what I want to do is check on canRegister whether the values on the config are valid or not

[dense drift]

Uh, It should be before I guess

[static jewel]

https://github.com/PlaceholderAPI/PlaceholderAPI/blob/a2456c582d4381da68384011bcfa17462b357818/src/main/java/me/clip/placeholderapi/expansion/manager/LocalExpansionManager.java#L216-L221 oh you're right

maybe I should fallback to defaults or something since the values won't exist yet on canRegister

[dense drift]

Yup, I was looking for that but it takes time on mobile xD

[static jewel]

[floral beacon]

is there a way to use BukkitRunnable#runTaskLater at some method but while it is being counted down until its actual execution, to execute next part of the code that comes right after that BukkitRunnable?

[wheat carbon]

just.. put code after #runTaskLater?

not understanding the question

[floral beacon]

thanks for the answer, that will be it
i just thought that it will wait for #runTaskLater to finish and after it is executed fully, then execute code that comes after it

[wheat carbon]

nope

for future reference, maybe test it out before asking the question

[river solstice]

very true and real ^

[past ibex]

didn't liveoverflow purposefully leak his own ip?

yeah, looks like he did

[past ibex]

no, there shouldn't be a packet for this

[spiral prairie]

I am currently thinking about finnicking a solution to prevent PieRay (seeing tile entities in the F3 chart) and I am thinking about what I have to check for. Are tile entities sent via the chunk data packet or separately?

Looks like this: https://wiki.vg/Protocol#Block_Entity_Data

[floral beacon]

How can i execute one BukkitRunnable (#runTaskTimer) and after it is cancel(), to execute next one?

[river solstice]

 () -> {  
   cancel()
   .. create new runnable?
}

not sure if that's the way tbh

[dense drift]

you can create a class that extends bukkitrunnable and on the cancel method, start a new task

[floral beacon]

should i try #runTaskTimerAsynchronously?

[dense drift]

What do you want to do?

[floral beacon]

i want to repeatedly send bossbar for x seconds to user
when he does what i want, that task will cancel and i want to execute new one (when the first one has been cancelled)

[minor summit]

you don't need an asynchronous task for that

the only cases where you really want things to be asynchronous is when
a) you are performing IO calls (file read/write or network ops, like database queries or HTTP requests etc)
b) you are performing some really heavy number crunching

sending a bossbar update every few seconds is neither of those, if anything it is just ever so slightly worse (not that it's anything noticeable either, but it is)

[river solstice]

Why is it bad to run async?

[dusky harness]

probably to be on the safe side (as many things cannot be ran async)
And if it's not performance-intensive (emily mentioned 2 examples), there's little to no performance benefit

[icy shadow]

thread switching isnt free

and neither are threads themselves

the more work you do asynchronously the more work the scheduler has to do, which could require creating more threads for the pool (which has a very non-negligible performance impact)

plus yeah many issues can arise from doing lots of work async (race conditions, collection issues, etc)

[signal grove]

any idea why this actually heals armor durability?? im kinda baffled

public static void damageArmor(Player player)
    {
        Random random = new Random();
        for(ItemStack armor : player.getInventory().getArmorContents())
        {
            if(armor != null)
            {
                int unbreaking = armor.getEnchantmentLevel(Enchantment.DURABILITY);
                float chanceOfDamaging = 1.0F / (unbreaking + 1.0F);
                if(random.nextFloat() < chanceOfDamaging)
                {
                    armor.setDurability((short) (armor.getDurability() - 1));
                }
            }
        }
    }

also i know get and set durability are deprecated

but i doubt they would still be that wrong

[dense drift]

you need to increase the durability iirc

iirc durability is more like "health missing" not "health left"

[signal grove]

horrible naming

[dense drift]

nah horrible api xD

[signal grove]

yeah

especially when in game tool tips show durability as something that decreases over time

thanks that fixed it by making it +1

[minor summit]

what BM + plus you run the risk of things like thread exhausting, where there are more threads trying to actively run than the platform can handle, slowing things down further since now you have threads waiting for other threads to finish before they have a chance to run

async does not mean "performance"

deadlocks are quite a fun thing to run into and debug

[dusky wolf]

    public long getRemainingProtectionTime(Player player) {
        long remainingTime = 15;
        if (TownyWildTownEventListener.scheduledRemovalTimes.containsKey(player.getUniqueId())) {
            Plugin plugin = Bukkit.getPluginManager().getPlugin(getPlugin());
            assert plugin != null;
            new BukkitRunnable() {
                int remainingTime = 15;

                @Override
                public void run() {
                    this.remainingTime--;
                    if (remainingTime == 0) {
                        cancel();
                    } else {
                        player.sendMessage("You got " + remainingTime + "left");
                    }
                }
            }.runTaskTimer(plugin, 20, 20);
        }
            return remainingTime;
        }```

For some reason my bossbar doesn't update the remainingTime

        String bossBarText = PlaceholderAPI.setPlaceholders(player, String.valueOf(remainingTime));
        bossBarText = bossBarText.replace("%townywild_countdown%", String.valueOf(remainingTime));
        bossBarText = ChatColor.translateAlternateColorCodes('&', bossBarText);
        double timeDecrease =  (double) 0.1 / remainingTime;
        double progress = ((double) scheduledRemovalTime);
        System.out.println(progress + "%");
        if (progress < 0) {
            progress = 0;
        } else if (progress > 1) {
            progress = 1;
        }
        bossBar.setProgress((float) Math.max(0.0, bossBar.getProgress() - timeDecrease));
        bossBar.setTitle(bossBarText);
        if (remainingTime < 0) {
            bossBar.removePlayer(player);
            listener.remove(uuid);
            Bukkit.getScheduler().cancelTask(taskId);
            }```

https://imgur.com/a/mPEaY8G

text gives updates for player.sendMessage("You got " + remainingTime + "left"); but the bossbar stays at 15

[dark garnet]

anyone know of a java library for YAML that is similar (as close as can get) to bukkit/spigot's?

[dusty frost]

you can use snake yaml (the one bukkit uses) yourself lol

[dark garnet]

im trying but i miss the luxuries of simply using set(String, Object)

unless im just using snake yaml wrong

[dusky harness]

🤢

[dark garnet]

:(

[dusky harness]

Doesn't Configurate support that?

https://github.com/SpongePowered/Configurate/wiki/From-Bukkit-Configuration

@dark garnet

[dark garnet]

ooooo ty

[sterile hinge]

Well just don’t synchronize/lock 🤓

[icy shadow]

There’s some platform agnostic port for the bukkit yaml api

But also yeah consider just not doing that

Object mapping >>>

[supple oar]

so real

[sharp cove]

Hey, is it possible to make a GitHub repository with a password?

So some people can view it?

[dense drift]

yes, it is called a private repository

and then you give access to each person individually

[sharp cove]

Ah..

But it has to be a user?

Like not a password?

[dense drift]

hm?

[sharp cove]

Like is it not possible to set a password for a git?

[dense drift]

no

[sharp cove]

Ahh

Oke

Thank you

[proud pebble]

it kinda makes sense,
durability for items is hardcoded, damage is stored on the itemstack, quick comparison of itembasedurability - currentitemdamage.

[spiral prairie]

What

[proud pebble]

well theres no reason to store the true durability in the nbt data of the itemstack

since its the same every time

how much damage the item has taken does change

i can see why setDurability is deprecated since its misleading

setDamage is much more descriptive of what it does

[dusky harness]

Well
Technically can I thinj
Can make an acc for that repo only 🙃

But there's no built in way

[inland meadow]

I currently have an invisible, invulnerable baby rabbit that a player has to hit, but I cannot find any event that actually gets triggered by the player punching the rabbit.
I've tried various interact events but none seem to do anything as long as it's invulnerable/invisible.
Tried my best to find a solution, so asking here as a last resort

[dusky harness]

Try making it vulnerable and cancel entitydamagebyentityevent

[inland meadow]

I'll check that, but iirc when it was invisible it still didn't trigger the events

that worked

thank you a lot 👌

[dusky harness]

Np 👍

[inland meadow]

I misread the event, I thought this was EntityDamageEvent aswell, but this one is from the perspective of the hit entity

[sharp cove]

Hahaha yeah oke

[dense drift]

Is possible to detect when the social interaction screen is opened?

[spiral prairie]

the what?

did I miss a new MC feature or

[dense drift]

Press P

[spiral prairie]

that's client side afaik

although dont take my word for it

[weary delta]

can any1 help me i was making bal leaderboard with %vault_eco_top_player_1% %vault_eco_top_balance_1% and its not working can any1 tell me how to fix this

[broken elbow]

Umm. Wrong channel. #placeholder-api is the correct channel. Either way, those placeholders don't exist anymore. They were moved into the Essentials expansion.

[weary delta]

then can you pls tell me essential command to create bal leaderboard

[river solstice]

there's no essentials command to just 'create a leaderboard'

[weary delta]

then how can i create bal top leaderboard

[river solstice]

are you locked out from google

https://github.com/PlaceholderAPI/PlaceholderAPI/wiki/Placeholders#essentials

[weary delta]

alr thanks

got it

[river solstice]

took me like 15 seconds to open this up.
you really could've done that yourself instead of trying to ask someone to spoonfeed you this information.

[dusky harness]

harder if you don't know where to go

although

it is on the spigot page

[river solstice]

well blitz already said they were moved to essentials expansion

[dusky harness]

🙃

also for some reason it isn't listed here

🤔

[river solstice]

hardcoded?

[dusky harness]

should still be listed

ig they didn't update it

[lyric gyro]

im assuming to create a worldguard region i have to install the worldguard api?

[dusky harness]

not sure what you mean by install but you've got to import it into your project, yes

[lyric gyro]

ok lol was just wondering if the worldedit api handled that but no sadly

[dusky harness]

🤔

[proud pebble]

worldguard and worldedit are seperate plugins

https://github.com/HelpChat/ChatChat/

I have an error compiling the ChatChat plugin

[dusky harness]

But you can use dev builds - https://ci.extendedclip.com/job/chatchat/

[lyric gyro]

wait sorry

[dusky harness]

seems like dev build was last updated 15 days ago

¯_(ツ)_/¯

[lyric gyro]

The thing is that I want to have the src of the plugin to customize it but it gives me a compilation error

ooow

no

[dusky harness]

it seems like that's what Github Actions does so maybe it'll work?

[lyric gyro]

I'll see

[dusky harness]

or actually it seems like that build log also failed so probably not

what java version do you have installed?

and what program are you running the command in?

[mental cypress]

Do you only have Java 8 or something installed? It's complaining about the Java version you are using to compile it.

[lyric gyro]

Git bash and i have Java 8 but Gradle install jdk's

ooooow

ah no

what if you do javac -version

[lyric gyro]

javac 17.0.6

I'll go change it

[dusky harness]

no 17 is good

[wooden valley]

Hi, is this the help server for the Stronger diamond swords mod?

I made a diamond sword and typed the command /diamondsword 10 and it only gave me 3 diamond swords instead of 9

how do you craft the diamond swords together? It doesnt work for me

[shell moon]

i doubt it, this is HelpChat for PlaceholderAPI, and plugins from funnycube and clip

afaik this is not support of a mod like t hat

[wooden valley]

yeah, I crafted them

[shell moon]

[wooden valley]

what do you mean? 😂

[torpid raft]

very common mistake here

[wooden valley]

what is

[torpid raft]

the author of that mod is actually maranthi so the plugin only recognizes item ids written in maranthi

so instead of diamond sword you'd write "हिरा तलवार"

[wooden valley]

yeah thats real funny man, minecraft is english not a chinese server 🤣

and why would i write in chinese if my game is made english Lol

[torpid raft]

actually minecraft is multicultural

people from all areas of the world can enjoy it

[wooden valley]

yeah but my diamond sword is english

and this mod is english im pretty sure

[torpid raft]

yes that's why it is not working

[wooden valley]

what do you mean XD

[torpid raft]

i'm telling ya you need to call it हिरा तलवार

[north robin]

I try running the command /papi ecloud download skript and it says theres no skript expansion found anybody have an idea on this?

1.19.2 papi version 2.11.2

[wooden valley]

what do I need to call that

and why

[torpid raft]

you need to replace diamond sword in your command with that

[wooden valley]

the mod is supposed to give you diamond swords or make your one holded stronger

if you write /diamondsword 10 it gives 10-amount of swords in inventory

[torpid raft]

10 diamond swords is a lot of diamond swords

what are you doing with 10 diamond swords

[wooden valley]

if you add a my word at the end it will add strength to the current one

i need this to make stronger kits for my server

but its not working

[torpid raft]

i think 10 is too strong

maybe 7 or 8 at most

be reasonable

[wooden valley]

sure but why will it not work

[torpid raft]

beats me this isn't the help discord for that mod

i suspect that not a single person here has heard of it

considering it doesnt even come up in a google search

[wooden valley]

Lol it is the most popular mod on forge

first result https://www.curseforge.com/minecraft/mc-mods/mo-creatures#:~:text=Mo'%20Creatures%20is%20a%20mod,clicking%20the%20wiki%20link%20above.

over 7 mill downloads

[torpid raft]

that looks a lot like a mod that has nothing to do with diamond swords

[wooden valley]

uhh, have you ever used the mo creatures mod?

it is everything

yesterday it all worked fine and things are good now i switch to cauldron things break I need to use plugins on my server because there is no other way to make my players use things like fly and kit

and i need kit

[torpid raft]

if it had everything it should have a feature to teach you how to use the command correctly

[wooden valley]

thats why they created this server

[torpid raft]

well i guess if it did have everything it would also have this server

[wooden valley]

there are to many things in the mod lol

[torpid raft]

that adds up

[wooden valley]

what adds up

the command is subtraction

[torpid raft]

what is subtraction if not addition but backwards

[wooden valley]

wut

🤔

[torpid raft]

did you know the word addition reversed makes subtraction

[wooden valley]

lets not change the sentence

im in need of help very urgently

[torpid raft]

will you pay me for my time

[wooden valley]

why?

[torpid raft]

because i want money

i think it's only fair

[wooden valley]

yee take 💰

🤑

[torpid raft]

nah i'll take some btc or xmr tho

[wooden valley]

wut are those words

oh, bitcoin LOL.

[torpid raft]

i'll take $10 for my time

[wooden valley]

you didnt even do anytihng

[torpid raft]

i will

[wooden valley]

haha you are just trying to mess around with me right

[torpid raft]

nono

i would never

[wooden valley]

I got news I dealt with you are not different

[torpid raft]

feel free to send the money and i can make you as many diamond swords as you'd like

837qe5doGT1QLnr16qVD5jNx72HFX5LU7LAaFw46Tjj2QstzbSHrUGBfvWFVFjmPf19EYN8b3ULtRZxWe49BVHeQ7G1ayGB

[wooden valley]

spamming ^

[torpid raft]

yes spam that address with money

[wooden valley]

im good 😄

[torpid raft]

then no diamond sword for u

[wooden valley]

that was never my problem

Lol

[torpid raft]

what was your problem

[warm steppe]

Bruh some dude uses not-paper server software and wonders why nothing works

Uhh im using fabric, why is my server lagging and not being able to hold 20 players

Get real

[shell moon]

rain particles are client side right?

I mean, i cannot use protocol lib for example to interecept rain particles and change it for other particle

(dumb question, but still)

[spiral prairie]

yes

[proud pebble]

no, this server has no association with that mod

also thats not chinese

thats goan konkani according to google translate, i thought it was hindi at first

[signal grove]

rain particles are clientside, yes, but the server tells the client that it is raining

so you have the option to not send that, and instead send your own custom particles

[proud pebble]

afaik rain isnt particles, they are a cascading texture or something

[signal grove]

that seems right because they dont move like normal particles

actually i dont think youll need protocollib at all

you can use a WeatherChangeEvent, then use player.setWeather

 @EventHandler
    public void onRain(WeatherChangeEvent event)
    {
        for(Player player: Bukkit.getOnlinePlayers())
        {
            //if event is rain
            //    player.setPlayerWeather(WeatherType.CLEAR);
            //    add them to a list of people to send particles to
            // else if event is clear
            //    remove from list
        }
    }

bad code but you get the idea

[proud pebble]

rain is a texture, but there are particles that spawn on the floor but im not sure if they are hardcoded or not

[spiral prairie]

yeah they are

i mean maybe the texture isnt

but the server isn't sending thousands of particle packets

[signal grove]

when in the desert, you can't see anything happening in other biomes

so it must make those particles clientside

[minor summit]

they are client sided

the server only sends if it's raining or not

[shell moon]

but making it look like other particle would require getting player location and spawning the particles randomly around the player right?

[signal grove]

yes

[hoary scarab]

Any reason windows command prompt shouldn't be displaying colors?
System.out.println("\033[36mcyan\033[0m"); -> ←[36mcyan←[0m
I've also tried "\u001b[36mcyan\u001b[0m", "\u033[36mcyan\u033[0m"

[minor summit]

what does the second one look like when printed?

[hoary scarab]

System.out.println("\033[36mcyan\033[0m"); -> ←[36mcyan←[0m
System.out.println("\u001b[36mcyan\u001b[0m"); -> ←[36mcyan←[0m
System.out.println("\\u033[36mcyan\\u033[0m"); -> \u033[36mcyan\u033[0m

[hoary scarab]

Out of ideas lol

[proud pebble]

that looks like its printing out unicode characters rather then colors

[dusky harness]

uhhhhh
fabric is a well known and used mod loader

think forge but better

[forest jay]

I want to track to know if a player has accepted a provided resource pack. Is there a way to do this through code? I want to display a GUI after they have accepted the pack.

[upper jasper]

https://jd.papermc.io/paper/1.19/org/bukkit/event/player/PlayerResourcePackStatusEvent.html

[forest jay]

thanks

[forest jay]

how can I tell if they have accepted it on a prior join, and it automatically loaded?

[dusky wolf]

I'm confused on what needs to be done here:

    @EventHandler
    public void ExitTownBorder(PlayerExitsFromTownBorderEvent event) {
        // Gets a player's UUID.
        UUID uuid = event.getPlayer().getUniqueId();
        System.out.println("Player just exited the town border");

        // Adds a player's UUID to the protectedPlayers list when exiting a town.
        protectedPlayers.add(event.getPlayer().getUniqueId());
        Bukkit.getScheduler().runTaskTimer(plugin, (Runnable) protectionTimeLeft, 0, 20);

        System.out.println(protectionTimeLeft + " seconds left of protection");
        System.out.println("protectedPlayers after adding player: " + protectedPlayers);
    }```

This part specifically:
```java
        protectedPlayers.add(event.getPlayer().getUniqueId());
        Bukkit.getScheduler().runTaskTimer(plugin, (Runnable) protectionTimeLeft, 0, 20);```

This is what I did:
```java
package com.agaloth.townywild.tasks;

import org.bukkit.Bukkit;
import org.bukkit.plugin.Plugin;
import org.bukkit.scheduler.BukkitRunnable;

import java.util.UUID;

import static com.agaloth.townywild.listeners.TownyWildTownEventListener.protectedPlayers;
import static com.agaloth.townywild.listeners.TownyWildTownEventListener.protectionTimeLeft;

public class RemoveProtectedPlayerTask implements Runnable {
    private final UUID uuid;

    public RemoveProtectedPlayerTask(UUID uuid) {

        this.uuid = uuid;
    }

    public void protectionTimeLeft() {
        if (protectionTimeLeft.containsKey(uuid)) {
            Plugin plugin = Bukkit.getPluginManager().getPlugin(this.toString());
            assert plugin != null;
            new BukkitRunnable() {

                int remainingTime = 15;

                public void updateProtectionTime() {
                    protectedPlayers.add(uuid);
                    this.remainingTime--;
                    if (remainingTime < 0) {
                        protectedPlayers.remove(uuid);
                        cancel();
                    }
                }
                @Override
                public void run() {
                    updateProtectionTime();
                }
            }.runTaskTimer(plugin, 20, 20);
        }
        protectionTimeLeft.getOrDefault(uuid, 0);
    }

    @Override
    public void run() {
        protectionTimeLeft();
    }
}```

Adding protectionTimeLeft would cause a ClassCastException since protectionTimeLeft is a HashMap in TownyWildTownEventListener but I want to take the protectionTimeLeft from RemoveProtectedPlayerTask and adding updateProtectionTime won't work (since it can't find it?) (Players never end up getting deleted from the protectedPlayers map after the countdown is over)

For information:         ``if (protectionTimeLeft.containsKey(uuid)) {`` uses ``public static Map<UUID, Integer> protectionTimeLeft = new HashMap<>();`` from TownyWildTownEventListener

[upper jasper]

Maybe by checking if the state changes to accepted through the process? Depends on if it also changes to that without redownloading

[hoary scarab]

Tried everything. Any ideas?

[signal grove]

does anyone know off hand - if calling player.damage(dmg, null) will invoke the EntityDamageEvent with event.getCause() == null?

no, apparently its not nullable

then my question is what happens to the damage cause

[lyric gyro]

would it be possible to create something with worldguard where if the player lands on a block outside of their region they're teleported back to their region?

[signal grove]

you mean, if theyre flying, or jumping in the air? then land on solid ground outside the region, they get teleported back?

you'd need to store a history of their last touched spot using onGround (probably deprecated) and then when they touch again, see if theyre within the desired region. If not, teleport them back to their last touched spot inside the region

[river solstice]

Everything is possible if you are brave enough

[signal grove]

figured it out - DamageCause.CUSTOM

[lyric gyro]

is player.getLocation().getBlock().getRelative(BlockFace.DOWN).getType() != Material.AIR) the best way to check if the player is on the ground since the isOnGround() method is deprecated.

[minor summit]

uh no that would be the worst tbh

[dusky harness]

idk the context but I'd consider it safe to use isOnGround

assuming the server has an anticheat

[minor summit]

in the vast majority of cases it'll probably be fine

[dusky harness]

and plus the first check would fail 10000x more than isOnGround anyways

afaik

[minor summit]

yeah you can stand on the edge of a block and the block beneath you will be air lol

or like standing on a bottom slab that's got nothing underneath it etc

[forest jay]

if you didnt want to use isOnGround couldnt you also just use a raycast that is the width of the player? that would account for the standing on edge.

and then you would just make the raycast a length of 1 block

idk, just a thought. not sure how isOnGround works, for all I know it could use a raycast

[spark skiff]

Sorry if this is a stupid question but i'm trying to create an inventory gui item that when clicked cycles through different selections in the lore:

Toggle Scoreboard Color (Red)
 » Red
 Blue
 Orange

I'm not sure how to get this working so if anyone can help that would be greatly appreciated (ping ok)

[past ibex]

no

please dont

All the ways this will fail:

• A player can stand on the edge of a block
• The player can stand on a shulker entity
• The player can stand on a boat entity
• The player is in cave air
• onGround occurs with YXZ movement order, so a player can be in midair while still being on the ground for one tick

and much more but it's a terrible idea

[past ibex]

yeah, standing on a slab

on a 1.8 client, hitting the ground while activating stepping movement so you hit the ground but stop mid-air vertically above the ground

allowing onGround stuff while in water, lava, non-full blocks, etc.

[fading stag]

I update a variable outside of a Runnable but I can't use new value of the variable at runnable :/

[dense drift]

I work on a KeyVault plugin and I've previously stored the amount of keys using NBT inside the vault item, now I was thinking to use sqlite for storage and the schema looks like this

CREATE TABLE IF NOT EXISTS `vault`
(
    id   INTEGER PRIMARY KEY,
    uuid VARCHAR(36) NOT NULL
);

CREATE TABLE IF NOT EXISTS `key`
(
    id       INTEGER PRIMARY KEY,
    vault_id INTEGER     NOT NULL,
    name     VARCHAR(32) NOT NULL,
    amount   INTEGER     NOT NULL,
    FOREIGN KEY (vault_id) REFERENCES vault (id)
);```
The players might get certain type of keys quite often (maybe 1 every second for the low level ones), is it ok if I update the data on database every time?

I will keep an in-memory cache as well for online players, so I won't constantly query the database for the data to update the key vault item visually (to display how many keys are stored inside).

[icy shadow]

Probably fine

Databases are designed for high throughput

[minor summit]

yeah it's fine

[little summit]

i've got a problem with my plugin, i can't find any errors or anything bad in my plugin atm but for some reason every time the plugin tries to load it fails. no errors other than [14:44:11 ERROR]: Could not load 'plugins/KitEditor-1.0.4.jar' in folder 'plugins'
or sometimes it just enables and then immedaitely disables.

i'm about to send the code.

[river solstice]

cool, why not just send in the whole project at this point

(weird how there are no error messages though, usually there's an obvious error message telling why it did not enable)

[minor summit]

lol

[little summit]

^

[little summit]

that's literally all of the classes.

[river solstice]

I'm joking obviously

you could at least put it all in one paste, not 30 different ones

[little summit]

oh i thought there was a char limit

anyways, any ideas on why this is happening?

any NPE's?

[river solstice]

well, remove everything from onEnable and go from there

though

what's this

      @Override
        public void onEnable() {
            Bukkit.getPluginManager().registerEvents((Listener) this, this);
            getCommand("editkits").setExecutor(new KitSelectGUI());
            getCommand("adddefaultkit").setExecutor(new KitEditorCommand());
            kitSelectGUI = new KitSelectGUI();
            kitSelectGUI.createInventories();

        }

Bukkit.getPluginManager().registerEvents((Listener) this, this);

you're casting main class which is not a listener and registering it

that's your issue

[little summit]

oh yeah

alr ty

[hoary scarab]

Huh.... So https://wiki.vg/Protocol says the Login Start packet should be Name, Has Player UUID, Player UUID
But I am getting an output that contains the server IP then my username as well as some other data.

The packetsize alone should be more then 16... UUID -> 16, String -> 16, Boolean -> 1

And if I attempt login again the data past the username is removed

[icy shadow]

the only packet that sends the IP is the handshaking start

so you must not be reading it properly

[little summit]

nevermind, same error
doesn't load at all.

the version is correct (i double checked like three times already)

[little summit]

package me.defusemc.kiteditor;

import org.bukkit.Bukkit;
import org.bukkit.event.Listener;
import org.bukkit.plugin.java.JavaPlugin;

public class Main extends JavaPlugin implements Listener {
    KitSelectGUI kitSelectGUI;
    @Override
    public void onEnable() {
        Bukkit.getPluginManager().registerEvents(this, this);
        getCommand("editkits").setExecutor(new KitSelectGUI());
        getCommand("adddefaultkit").setExecutor(new KitEditorCommand());
        kitSelectGUI = new KitSelectGUI();
        kitSelectGUI.createInventories();

    }
}

[hoary scarab]

sigh It sends the Handshake and the LoginResponse in the same packet.

[icy shadow]

🤨

i dont think it does

[river solstice]

why are you registering the Main class as a Listener if it does not have any handlers

also try to use something different than Main, ex. KitsPlugin or something like that

does your plugin.yml have editkits and adddefaultkit defined as commands?

[hoary scarab]

It does.

Now its just the UUID giving me problems lol

[little summit]

yeah, they are defined there

[little summit]

you said it's not a listener so i made it a listener lol

when I remove the listener implementation then it gives me a error:

'registerEvents(org.bukkit.event.Listener, org.bukkit.plugin.Plugin)' in 'org.bukkit.plugin.PluginManager' cannot be applied to '(me.defusemc.kiteditor.Main, me.defusemc.kiteditor.Main)'

[icy shadow]

it quite literally does not

you're decoding something wrong

they are 100% sent as distinct packets

[hoary scarab]

Yes they are separate. I didn't explain it right. I can read both of there data in succession is what I meant. I thought it would have something between the packets.

Also the way I read the packets was a factor in this. So all data comes in at once.

Anyway I got it to work 😄

[edgy lintel]

developerden.net/discord does not work

💯

[icy shadow]

Uh yeah no that’s not how sockets work lol

[edgy lintel]

looking forward to your standalone packet framework

[past ibex]

technically speaking, the size of second packet is between the packets

[icy shadow]

now it does

[hoary scarab]

Let me explain it like this then...
When you click login, on DataInputStream I can read both the handshake and the loginstart.

[past ibex]

so you can do real fun stuff like sending one packet but it actually having two packets

[edgy lintel]

nice server set up

[icy shadow]

indeed you can

thanks

[past ibex]

maybe, the splitter might get angry at you

[hoary scarab]

Yeah I thought originally it would be separated by something lol

[edgy lintel]

now that you mentioned it,
im gonna look at the legacy code of mc for the third time

might as well make my own packet framework to mess with

[past ibex]

the best packet framework would be to copy packetevents 2.0 and rewrite everything except the injector (Injectors suck.) and wrappers

what the fuck is the Varint21FrameDecoder decoder doing

https://pastebin.com/w7KSUXgs

wouldn't this only loop once

oh wait nevermind, i'm stupid

It's letting you send a 21 bit number

so max packet size is 2097152 bytes

yep

[little summit]

any ideas?

package me.defusemc.kiteditor;

import org.bukkit.Bukkit;
import org.bukkit.event.Listener;
import org.bukkit.plugin.java.JavaPlugin;

public class Main extends JavaPlugin implements Listener {
    KitSelectGUI kitSelectGUI;
    @Override
    public void onEnable() {
        Bukkit.getPluginManager().registerEvents(this, this);
        getCommand("editkits").setExecutor(new KitSelectGUI());
        getCommand("adddefaultkit").setExecutor(new KitEditorCommand());
        kitSelectGUI = new KitSelectGUI();
        kitSelectGUI.createInventories();

    }
}```

[edgy lintel]

give that full error
probably something wrong with your plugin.yml

[little summit]

that's literally the only error LOL

[edgy lintel]

normally there are descriptions ensuing the "could not load plugin in folder"
and we need that to check the issue

[little summit]

normally, however in my case there is none. let me try checking agai

n

[edgy lintel]

right not descriptions but error stack trace
still kind of descriptions i guess

[edgy lintel]

thats very weird

[shell moon]

just wondering, whats the issue here

[edgy lintel]

probably paper loads plugin async and error gets covered

[little summit]

Is it because I should have it implementing listener and then changing the @override to a eventhandler or something by any chance?

[edgy lintel]

try adding pair of ' '
for all the descrptions

[little summit]

i doubt that would change anything

[edgy lintel]

nvm valid yaml

[little summit]

?
