[tardy delta]

maybe if you move the datapack to the datapacks folder and restart the server

[grim ice]

Hey

so uh

anyone has an idea of what to start with if I wanna learn AI

ik thats too generalized but im not sure with what to start

[harsh totem]

Does anyone know why it crashes my server?

    public void DeadlyLava(PlayerMoveEvent event){
        Player player = event.getPlayer();
        if (player.getLocation().getBlock().getRelative(BlockFace.DOWN).getType() == Material.LAVA){
            while (player.getHealth() > 0){
                player.damage(1);
            }
        }
    }```

[terse raven]

if you know how to use js, then i think brain js would be easy to start with https://brain.js.org/#/

[terse raven]

just set his health to 0 wtf

[grim ice]

cant i do it with java lol

im most comfortable with java

[terse raven]

just found this library to be really easy

[grim ice]

hmm

i wnna t ry deeplearning4j

but i dont really get how to use it

[terse raven]

then do it

look at the examples

and docs

[harsh totem]

I wat the player to get damage very fast and not instantly die

[terse raven]

if you just while loop

without delay

he will insta die too

[tardy delta]

why is it crashing

[terse raven]

damage with a value of one

is probably cancelled

[harsh totem]

how do I delay it?

[terse raven]

so his health never reaches 0

or something and gives an infinite loop

[harsh totem]

?

[tardy delta]

?scheduling

[undone axle]

https://www.spigotmc.org/wiki/scheduler-programming/

[grim ice]

ok i dont get it

[terse raven]

then use an easier library, will probably not be able to make ai that advanced, but you should start small

[grim ice]

i literally

just wanna make

a rock paper scissors

ai

lmfao

nothing can get simpler than this

[terse raven]

https://github.com/arifikhsan/batu-gunting-kertas-nuxt

literally a brain js example

[tardy delta]

why doing ai in java btw?

[terse raven]

probably wants it in his plugin or something

[terse raven]

https://github.com/josephmisiti/awesome-machine-learning#java

this seems like a good resource

it lists a bunch of good and free machine learning frameworks for java

[astral shard]

although I hate python I have to admit that it has one of the best libraries providing exactly what you're looking for

For example numpy which is written in C making it faster than it would've been if it was written in python

[harsh totem]

How do I get the plugin?

                scheduler.runTaskLater(plugin, () -> {
                    player.damage(1);
                }, 20L * 30L);```

[quaint mantle]

I have a question, i use on my server tree twerk and its just enabled with op on the server, please say me how to fix

[green prism]

Hi guys, I created a plug-in with the use of placeholderapi. I used JAVA 8 in 1.16.5 but unfortunately placeholders are not registered in 1.18 with java 17, what could I do in your opinion to create a multicompatibility?

[harsh totem]

@quaint mantle The problem was that I need a delay in the while loop. can you help me here please?

[tardy delta]

?di to get the plugin

[undone axle]

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

https://www.spigotmc.org/wiki/scheduler-programming/

[green prism]

Help me pls

[harsh totem]

So I get the plugin like this? Main plugin = new Main();

wdym

what is "yaw"

[tardy delta]

get the plugin instance via the constructor

class MyPlugin extends JavaPlugin {
  void onEnable() {
    new ClassThatNeedsPlugin(this);
  }
}

class ClassThatNeedsPlugin {
  private final MyPlugin plugin;
  ClassThatNeedsPlugin(MyPlugin plugin) {
    this.plugin = plugin;
  }
}```

[harsh totem]

Cannot assign a value to final variable 'plugin'

shouldn't it not be final?

[tardy delta]

are you doing it in the constructor?

[harsh totem]

yes

[tardy delta]

show code

[harsh totem]

oh nvm

i fixed it

[peak jetty]

hi so i would like to tp the command sender to the target but player.teleport is not working for me, this is my code:

    @Override
    public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
        if (command.getName().equalsIgnoreCase("spectate")) {
            Player target = sender.getServer().getPlayer(args[0]);
            if (target == null) {
                sender.sendMessage(ChatColor.GOLD + args[0] + ChatColor.AQUA + " is not currently online.");
                return true;
            }
            player.teleport(target, PlayerTeleportEvent.TeleportCause.COMMAND);
        }
        return false;
    }```

[tardy delta]

uhm sir youre not checking the length of the args

[quaint mantle]

I keep getting this error, trying to add citizensnpc dependency
Could not find artifact net.citizensnpcs:citizens-main:pom:2.0.29 in everything (https://repo.citizensnpcs.co/net/citizensnpcs/citizens-main/2.0.29-SNAPSHOT/)
the pom.xml code has been pasted below

?paste

[undone axle]

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

[tardy delta]

do player.teleport(target.getLocation())

[peak jetty]

i get this error: Cannot resolve symbol 'player'

[quaint mantle]

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

here is the pom file

anyone can help me?

or do I need to ask the citizen server thing

[eternal night]

I mean you never define a variable called player ?

[tardy delta]

bruh

i see

[peak jetty]

im new to this, how do i do that

?

[eternal night]

Follow whatever tutorial you are following

You need to instanceOf check the sender

And then cast

But your tutorial should show you that

[tardy delta]

if (sender instanceof Player) { Player player = (Player) sender }```

🥣

[eternal night]

🥄

[tardy delta]

🍴

smh

[harsh totem]

I have this code but it only works in the first time it is executed since the plugin is reloaded

    public void DeadlyLava(PlayerMoveEvent event){
        Player player = event.getPlayer();
        if (player.getLocation().getBlock().getRelative(BlockFace.DOWN).getType() == Material.LAVA){
            while (player.getHealth() > 0){
                BukkitScheduler scheduler = Bukkit.getScheduler();
                Main plugin = new Main();
                scheduler.runTaskLater(plugin, () -> {
                    player.damage(1);
                }, 10L /*<-- the delay */);
            }
        }
    }```

[harsh totem]

Player player = (Player) sender;

[eternal night]

You are blocking the main thread

[tardy delta]

please

please

read what i sent

are you?

[harsh totem]

?

[peak jetty]

THANK YOU

[tardy delta]

doing things like while(true) {} will block the whole server so thats why you need to use the scheduler

[eternal night]

No

[harsh totem]

but first check if the sender is an instance of a player because the command could be executed from the console

[harsh totem]

** I use it**

[eternal night]

Fourteen literally already posted that

😭

[tardy delta]

🥲

im really sad now

[harsh totem]

.

[eternal night]

You are using the while look outside the scheduler

Mate

[tardy delta]

someone has to hug me now

[eternal night]

It isn’t rocket science here

[harsh totem]

im not

[eternal night]

I’d give you a hug fourteen but this is too depressing

Also generally speaking a while loop is never the answer

You want to run a task timer

[harsh totem]

I just want it to execute every 0.5s

[eternal night]

Run a task timer that ja a Delay of 10 ticks

[tardy delta]

read the docs about scheduling

[eternal oxide]

while loops are for iterating. Scheduling is for repeating tasks

[eternal night]

Roughly 500 ms

[tardy delta]

still depends on the tps but ye

[harsh totem]

I says I can do .runTaskTimer(plugin, 20L * 10L /*<-- the initial delay */, 20L * 5L /*<-- the interval */);
but my IDE says Cannot resolve method 'runTaskLater(Main, <lambda expression>, long, long)'

[eternal night]

Carefully read the method name

You got this

[quaint mantle]

anyone?

quack quack

[ivory sleet]

?ask

[undone axle]

If you have a question, please just ask it. Don't look for staff or topic experts. Don't ask to ask or ask if people are awake or available. Just ask the question to the channel straight out, and wait patiently for a reply. Make sure you use the right channel regarding the topic of your question. Create a thread in case the channel is already in use!

[mellow edge]

is there any way to use something like "PlayerChangeBlockEvent" instead of player move event

[eternal night]

No

[mellow edge]

can I do it somehow with PlayerMoveEvent

[harsh totem]

I get Plugin already initialized!

in the console

[peak jetty]

hey how can i hide player from target's tab?

[eternal night]

Don’t create a new instance of your plugin

[eternal oxide]

You can not create a new instance of your main class. There is only one and it is created by Spigot

[harsh totem]

I haven't created an instance tho

    public DeadlyLava(Main plugin) {
        this.plugin = plugin;
    }```

it's what he sent

[eternal oxide]

Somewhere else you have

[eternal night]

Most likely where you create the class

[harsh totem]

oh

[eternal night]

DeadlyLava

[harsh totem]

i got it

[ivory sleet]

remove any new Main()

[harsh totem]

yes yes

i found one

thx

[dark arrow]

public class StrengthZombie extends EntityZombie {
public StrengthZombie(Location location){
super(EntityTypes.be,((CraftWorld)location.getWorld()).getHandle());

}

I unable to use this code and it give me error"x()' in 'net.minecraft.world.entity.EntityInsentient' clashes with 'x()' in 'net.minecraft.world.entity.EntityLiving'; attempting to use incompatible return type"

[eternal oxide]

1.18 I assume?

@dark arrow ^

[flint coyote]

yes. You can check whether .getBlockX() changed (same for y and z obviously)

[dark arrow]

yup

[eternal oxide]

You should be using the mojang mappings if you're using NMS on 1.17+

[dark arrow]

i am

[harsh totem]

for some reason the scheduler repeats every seconds instead of 1/10 of a second

[eternal oxide]

?bootstrap read the 1.18 nms section AND the 1.17 post it links to

[undone axle]

Bootstrap Jar
The main spigot-1.18.jar is now a bootstrap jar which contains all libraries. You cannot directly depend on this jar. You should depend on Spigot/Spigot-API/target/spigot-api-1.18-R0.1-SNAPSHOT-shaded.jar, or the entire contents of the bundler directory from your server, or use a dependency manager such as Maven or Gradle to handle this automatically.

[eternal oxide]

EntityTypes.be is NOT a mojang mapping

Your exact error https://www.spigotmc.org/threads/nms-entity-problem.542187/

[wind tulip]

Does the Inventory#remove method remove all items? Or is it just Inventory#removeItem under a different name

I checked the docs and it looks like the latter but I'm just making sure

[quaint mantle]

remove removes every item that is equal to that item

?jd-s

[undone axle]

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

[quaint mantle]

the code

[wind tulip]

I'm asking if the amount matters 🤦‍♂️

[quaint mantle]

yes

like i said

[wind tulip]

ok

[quaint mantle]

.

it says that in the docs

[wind tulip]

and like I said

I checked the docs

[river oracle]

Nice just test it then

[quaint mantle]

if the docs says the amount matters, then it matters?

[spiral hinge]

Hey if I have a string in my messages configuration file and someone uses a formatting or color code like &7, how do I get it so that it will actually show the format or color with the sendMessage method?

[crimson terrace]

you should get that as an extra value

and then call ChatColor.of()

[river oracle]

Translate color codes method from CharColor class should do you well

[eternal oxide]

a repeat of 2 = 2 ticks. Its running 10 times a secoond

20 = once per second

[harsh totem]

that's what I want but it repeats every 1s instead of 1/10s

[spiral hinge]

Wdym by this?

[crimson terrace]

save the nameColor as one value in the config and the actual name string as another

then you can do ChatColor.Of(config.getString())

[crisp steeple]

pretty sure .damage() has a cooldown on it

or at least it doesn’t update properly client side, i remember having issues trying to damage very quickly

[harsh totem]

how do i bypass this

[quaint mantle]

what

it repeats 10 times every second

[quaint mantle]

^ I tried to ask the question in citizens server, and I keep getting muted for exsisiting

exsisting

[quaint mantle]

here is the error

can anyone help?

[eternal oxide]

You are probably being muted as you are not using the repo correctly

I'm guessing they already linked you to some wiki

https://wiki.citizensnpcs.co/API

[peak jetty]

hello im trying to add a player to onlineplayerlist that has been removed from the list

[tardy delta]

i guess thats the tab

[peak jetty]

this is my code:

target.getServer().getOnlinePlayers().add(player);```

[peak jetty]

yes

but i get this error: 'add(capture<? extends org.bukkit.entity.Player>)' in 'java.util.Collection' cannot be applied to '(org.bukkit.entity.Player)'

[eternal night]

What are you doing

[tardy delta]

uh thats the online player list that bukkit is keeping

[eternal night]

The list is immutable

Don’t even try to add a player

[tardy delta]

which i just wanted to say

[eternal oxide]

Um, adding to teh OnlinePlayers. You can not do

[tardy delta]

what are you tryin to do?

[peak jetty]

i have already removed a player tho and i want to add him back is there any way i can do so?

[eternal oxide]

You can;t manually remove an online player

[tardy delta]

^

[peak jetty]

i did tho target.getServer().getOnlinePlayers().remove(player);

[eternal oxide]

that did nothing

[tardy delta]

and did it give an error?

[peak jetty]

nope

if i cant remove the player or add the player is there a way i can hide and show it?

[tardy delta]

wHaT aRe YoU dOiNg?

[eternal oxide]

you are talking about tab lists?

[peak jetty]

yes

[tardy delta]

packets probs

[quaint mantle]

no I got muted for pining a staff

and then got banned

I tried

everything in the repo

[peak jetty]

how?

[quaint mantle]

I mean the wiki

[eternal oxide]

I just linked you the wiki. look at the very first section about accessing the API. Compare it to your pom entries

[jagged badge]

When you right-click on a fake block, it disappears. I'd like to disable that.
The only packet I found that blocked this is PacketPlayOutChangeBlock. The problem is that this packet not only blocks what I want, but also blocks the sendblockchange etc. Someone would know how to just block the right click (cancel interact event etc doesn't work)

[quaint mantle]

and those staff emmbers

dont give a shit about u

[quaint mantle]

I TRIED BOTH OF IT

[peak jetty]

how do it do my tab list show and hide?

[eternal oxide]

Look at your repository entry in your pom, and then look at what the wiki says to use

[quaint mantle]

dont press at the tab putton

[granite owl]

am i dumb why dont i find the durability flag under item meta?

xD

[quaint mantle]

Could not find artifact net.citizensnpcs:citizens-main:pom:2.0.29-SNAPSHOT in ess-repo (https://ci.ender.zone/plugin/repository/everything/)

U GUYS ARE THE BEST

[tardy delta]

[quaint mantle]

but im still getting a few erros

tho

[quaint mantle]

dont close ur ide pls

[eternal oxide]

What errors?

[harsh totem]

It crashes my client

    public void DeadlyLava(PlayerMoveEvent event){
        Player player = event.getPlayer();
        if (player.getLocation().getBlock().getType() == Material.LAVA || player.getLocation().getBlock().getRelative(BlockFace.UP).getType() == Material.LAVA){

                }, 0, 2);
        }
    }```

[eternal oxide]

oh my that is going to kill your server

you are creating a NEW task every move packet you are in or on Lava

there are Thousands of move packets

[harsh totem]

how do I not create a new task?

[eternal oxide]

You create a single task, outside the event, then either activate it or deactivate it in the move event

[harsh totem]

ok

[harsh totem]

what is the command that you run

what did you type

[peak jetty]

./unspectate Gizmo0o

[harsh totem]

idk

[crisp steeple]

i would assume they don’t have a spawn location

[peak jetty]

its a prob with this i think:
player.teleport(getServer().getPlayer(player.getName()).getBedSpawnLocation());

[peak jetty]

how do i make it so if they dont have a spawn location it would tp them to the worldspawn?

[harsh totem]

check if player.getbedspawn returns null

if it's null it not a location

[tardy delta]

why are you casting to sender three times?

[harsh totem]

How do I make it execute also when im standing still in lava?

    public void DeadlyLavaKill(PlayerMoveEvent event){
        Player player = event.getPlayer();
        if (player.getLocation().getBlock().getType() == Material.LAVA || player.getLocation().getBlock().getRelative(BlockFace.UP).getType() == Material.LAVA){
                scheduler.runTaskTimer(plugin, task -> {
                    player.setNoDamageTicks(0);
                    player.damage(1);
                    if (player.getHealth() <= 0 || player.getLocation().getBlock().getType() != Material.LAVA || player.getLocation().getBlock().getRelative(BlockFace.UP).getType() != Material.LAVA){
                        player.setNoDamageTicks(20);
                        task.cancel();
                    }
                }, 0, 2);
        }
    }```

[peak jetty]

what would the code be?

[harsh totem]

if (player.getBedSpawnLocation() != null){

}

[harsh totem]

I guess i'll switch to a different event

[tardy delta]

early returns aaa

look at your code

does it look like a pyramid

[harsh totem]

@tardy delta does player.getLocation() return the xyz of the head block or the leg block?

[tardy delta]

feet

[crisp steeple]

this seems like its gonna crash the server

[harsh totem]

why would it

[crisp steeple]

creating a repeating runnable every playermoveevent that runs every 2 ticks

[tardy delta]

elgarl explained

this looks like im typing 'egirl' lol

[harsh totem]

💀

[harsh totem]

will it work if I set the damageTicks of the player to 2 when he's in lava?

[crisp steeple]

idk

try it

[harsh totem]

ok

[peak jetty]

would this work or did i do it wrong?

            player.teleport(getServer().getPlayer(player.getName()).getBedSpawnLocation()); {
                if (player.getBedSpawnLocation() != null){
                    player.teleport(getServer().getWorld(player.getName()).getSpawnLocation());
                }
            }```

[crisp steeple]

its just youre effectively creating 20 repeating runnables every second a player is in lava

and each one of those is running 10 times a second

[tardy delta]

nullcheck the player you got from the server

[crisp steeple]

and theyre performing fairly expensive operations as well

[tardy delta]

and dont request it twice

it does a map lookup

[crisp steeple]

overtime that is gonna break the server

[quiet ice]

Why the heck should one use getServer().getPlayer(player.getName())

[peak jetty]

what does this mean?

[river oracle]

Null points error

[eternal night]

Ah yes I love the world that is named after my player name

[tardy delta]

having a personal world

[eternal night]

It’s a good flex

[peak jetty]

how can i change my code to fix the error?
player.teleport(getServer().getWorld(player.getName()).getSpawnLocation());

[eternal night]

Well what world do you want

[eternal oxide]

player.getWorld().getSpawnLocation()

[tardy delta]

only for premium users

[eternal oxide]

What world?

[peak jetty]

the default one

[eternal oxide]

Is it a world named the same as the player?

[peak jetty]

yes

[eternal oxide]

I don't understand noyes

[peak jetty]

yes

yes

[eternal oxide]

Is the player alreadyin that world?

[peak jetty]

i want it to tp the player to the spawn of the world wich the player is in

[eternal oxide]

then player.teleport(player.getWorld().getSpawnLocation())

no

[peak jetty]

oh ok

yes

thanks

👍

[tardy delta]

if i do heavy stuff in the async prelogin, that wont block the user from logging in right?

[eternal oxide]

They will not join until the async event finishes. but you are safe to delay a few seconds in it

[crisp steeple]

it would suck if i changed my name and lost my entire world

[tardy delta]

ah so it will block the user

then i probably confused it with smth else

owh ye i forgot

[harsh totem]

The player.damage(1) just kills the player instantly (it doesn't do it every 1/4 of a second, it just instantly kills me). I tried to remove it but then the lava didn't do the damage fast like I wanted.

    public void DeadlyLavaKill(EntityDamageEvent event){
        if (event.getEntity() instanceof Player){
            Player player = (Player) event.getEntity();
            if (player.getLocation().getBlock().getType() == Material.LAVA || player.getLocation().getBlock().getRelative(BlockFace.UP).getType() == Material.LAVA){
                scheduler.runTaskTimer(plugin, task -> {
                    player.setNoDamageTicks(0);
                    player.damage(1);
                    if (player.getHealth() <= 0 || player.getLocation().getBlock().getType() != Material.LAVA || player.getLocation().getBlock().getRelative(BlockFace.UP).getType() != Material.LAVA){
                        player.setNoDamageTicks(20);
                        task.cancel();
                    }
                }, 0, 5);
            }
        }
    }```

[eternal oxide]

It will kill you instantly because you are spawning (possibly) hundreds of tasks, each doing 1 damage 4 times a second

oh you are in teh damage event, even worse

[harsh totem]

how do I make it execute only 1 task?

[eternal oxide]

hundreds

[golden kelp]

id use a hashmap for each <player,boolean> and check if i already did the task

[eternal oxide]

one sec

[harsh totem]

so I need a hashmap of all the players in the server? how do i do that

[golden kelp]

Just make one in your main class

Next time a player kills entity,
check if they are in the hashmap. If they are, check if they already damage (by getting their key which is true or false).

If they are not in the hashmap, just add them into the hashmap

[eternal oxide]

?paste

[undone axle]

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

[eternal oxide]

https://paste.md-5.net/tirizewugo.cs If this throws a ConcurrentModificationException let me know

[golden kelp]

yea it will

wait

it wont

where is the set used

[eternal oxide]

I couldn;t remember if the forEach was iterated

[golden kelp]

nvm found it

so you shouldnt remove it while iteratiing

use removeIf method

[eternal oxide]

ah yep, forgot about that

[golden kelp]

inLava.removeif(x -> x == id);

iirc

[eternal oxide]

https://paste.md-5.net/usiweliyev.cs Not tested though

@harsh totem

[harsh totem]

it does like 3-5 hearts of damage every time

[eternal oxide]

actually 4 per second. Thats the speed you have the task set to run

[harsh totem]

yes but it does it a once instead of every 1/4 of a second

it does it every second

[eternal oxide]

no, it does it every 1/4 a second. your client just isn;t updating that fast

if you want to slow the damage down, increase teh timer delay from 5 ticks to 10

so twice a second

[harsh totem]

no there's no way. it does damage every second and it's not 1 hp

i just checked

[eternal oxide]

It does 4 damage per second, as I just told you

it runs 4 times every second (5 ticks) doing 1 damage every time

1 damage = half a heart

so it will be taking 2 hearts per second

[harsh totem]

that's what it should do but it activates every seconds and not 1/4

[harsh totem]

it takes more

[eternal oxide]

no it doesn't

not unless you are creating more than one listener

[harsh totem]

im not

[eternal oxide]

then that code I gave you will do 2 hearts per second, assumign you have not got any health scaling on

[harsh totem]

ok

[eternal oxide]

and assuming your server is not lagging to be able to run at 20 ticks per second

oh, fix this line, as currently your code will allow you to pop your head above the lava and stop taking damage java if (player.getHealth() <= 0 || (player.getLocation().getBlock().getType() != Material.LAVA && player.getLocation().getBlock().getRelative(BlockFace.UP).getType() != Material.LAVA)){

[tardy delta]

can i just add another <relocation></relocation> to shade something else?

ah noclassdef found

entire pom looks like this now

ay

what do we call indentation overuse

i forgot that term

[tardy delta]

too much indents or smth?

[grim ice]

nah it has a nam

e

[peak depot]

someone got ideas what to code?

[grim ice]

ok its name is pyramid of doom

[eternal oxide]

We'd be writing it if we did

[tardy delta]

what scope do i need again for shading something?

compile?

[eternal oxide]

yep

[tardy delta]

still noclassdef found brr

[sage dragon]

Make a plugin where Herobrine spawns in front of you and you die of a heart attack when you're too long in the dark

I'm sure it's fun to play with

Or make a Gravity Gun plugin, that one is definitely fun

[peak depot]

im trying the herobrine one thats sounds good thanks for your idea

[sage dragon]

You're welcome 🙂

[tardy delta]

aight it seemed to work now

nice file extension tbh

[opal juniper]

[golden turret]

how could i make it possible for the player to cross the worldborder?

[tardy delta]

i probably shouldnt use the extension

[coarse shadow]

when we place jigsaw block through code, can we change its direction?

[tardy delta]

isnt that some old block

[quaint mantle]

make your line shorter 😠

[coarse shadow]

it came in 1.14 it allows u to generate structures randomly

[tardy delta]

kekw

[crisp steeple]

you mean just walk through it?

[golden turret]

yes

[crisp steeple]

you cant do that

its prevented client side as well

[wind tulip]

Anyone know how to clear crafting slots? (The ones in the player inventory)

[golden turret]

alright so which packet is the one who sents the world border?

[echo granite]

any android developers?

[ivory sleet]

Ye

[echo granite]

I do not have a specific question, I need to talk to one in PMs.

[ivory sleet]

I did Android with Java tho

So might not be able to help (was some time since)

[echo granite]

I'm basically stuck with the entire topic of making responsive layout

what I was taught in school is to use DP for everything, and now in the real world where I want to release my app, it looks more than horrible on other devices

ConstraintLayout is a big headache

I'm lost

[ivory sleet]

I mean using dp is wise

[echo granite]

how is it wise? it's a constant size

you should never use dp lol

[quaint mantle]

Is there a way to set the priority of world initialization event to low, so it doesn't hit the performance as much?

[ivory sleet]

Myeah there are probably better ones in practice now

But it can be favored in certain scenarios to some other size types

[naive bolt]

whats the event that happens when someone uses this

[dusk flicker]

highly doubt there is an event for it

but I could be wrong

[ivory sleet]

Creative mode is duct taped

Really abhorrent to work with

[naive bolt]

im trying to make it so when an item is removed either mannualy or with that button it adds it back

[ivory sleet]

InventoryCreativeEvent or whatever it’s called might be of help

[naive bolt]

ah yea

[echo granite]

Everyone says to use ConstraintLayout now

but nobody shows a real example

I'm so lost

[ivory sleet]

Let me take a look at what that is

[echo granite]

I don't even understand how people made responsive layout prior to constraintlayout(which was released at 2016)

[ivory sleet]

Yeah well, I kinda “hard coded” it

[quaint mantle]

^

[golden turret]

wait

does it means that i can cross any border if the client wants to??????????

[left swift]

When I use my library in the multiple project (only for personal use) should I implement it manually adding library to the project structure or create maven artifact dependency using jitpack or smth like this?

[ivory sleet]

If you can put it on jitpack or sth

Since then it’s basically accessible from everywhere

[left swift]

Yeah, but when I use it in about 3 - 4 projects, personal use etc, putting it on the jitpack is better way than doing it manually?

[ivory sleet]

Maybe just put it in your local maven repository

[wary harness]

So got problem with softdpendcy
my plugin wont load after MythicMobs

my plugin soft depend

[golden turret]

how can i get the location based on the world border like this

[eternal oxide]

last I looked only Depend affects the actual load order

[wary harness]

really

[eternal oxide]

softdepend only makes sure they exist

[wary harness]

didn't know that

what can I do about it

[eternal oxide]

What issue are you having?

[wary harness]

because I got class which loads types of mythic mobs

so my plugin loads before Mmobs

and fires constructor which should store types of Mmobs to map

but they are not there yet because thing is null

[eternal oxide]

You are doing your loading in your onEnable?

[wary harness]

yes

[eternal oxide]

and does your plugin actually work without MM?

it it truly a soft depend

[wary harness]

yes it hooks as an option

it is soft depend it can work without it

[eternal oxide]

then detect MM in your onEnable, but schedule your init of your MM code 1 tick later

[wary harness]

it is token plugin which allows token drops

for mobs farmin etc

and mmobs are one of things

[wary harness]

well I thouht of that

[eternal oxide]

with softdepend you can never guarantee load order so you should never expect other plugins to be loaded before yours

[wary harness]

but was confused didn't knew that soft depend only check if plugin is there

[wary harness]

thanks for that info

I am lazy reader so probably slipped thru my eyes 🍻

[eternal oxide]

I don;t believe its actually written anywhere. I remember it from having this issue myself long ago in Towny.

[golden turret]

you guys

how can i draw lines based on the player location and world border

i will give an example

[quaint mantle]

@EventHandler(priority = EventPriority.LOW)
    void disableWorldLag(WorldInitEvent e){
        e.getWorld().setKeepSpawnInMemory(false);
    }```

Would this reduce lag when loading a world ?

The big lag spike that you get, when loading it.

[golden turret]

i would like to get the shortest line

[wary harness]

1 tick was not good or even 1 sec

so I made repeat task

which checks if plugin is loaded once a sec

and then loads thing and cancel task

[fallow violet]

maybe?

board.getTeam("RedTeam").setColor(ChatColor.RED);```

[fossil lily]

Is there an alternative for .isItem() on the 1.8.8 API?

[fallow violet]

oh, mmmh

[eternal oxide]

That seems like overkill. MM should be enabled by the time their onEnable finishes. 1 tick past that and all plugins are assumed enabled.

[fallow violet]

is there something like setGlowColor? @kind patrol

[wary harness]

thing which I said up still not working xd

looks like there is some other problem with Mythic api

[eternal oxide]

are you defining yoru reference to a static reference too early?

or is all access via Bukkit getPlugin?

[wary harness]

u were right

I was defining instance in class where I register event MythicMobDeathEvent

this helps

            @Override
            public void run() {
                if (pl.getServer().getPluginManager().isPluginEnabled("MythicMobs")){
                    mythicOn = true;
                    mythicMobs = MythicBukkit.inst();
                }

            }
        }.runTaskLater(pl,1);```

forgot I got it there

[quaint mantle]

So i currently havd a problem where when someone moves it doesnt cancel the command and there is no errors for this

[mortal hare]

Is it possible to instanciate generic array or generic fixed sized list?

new Foo<Baz>[50]; doesnt work, but Arrays.asList(new Foo<Baz>[50]; doesnt work either as you can see

there's a workaround to wrap interfaces inside subinterfaces with types already defined

but that would be a hassle to maintain in the long term, especially if there's no new functionality inside those interfaces

[ivory sleet]

class Sub derives Foo<Bar>{}

Sub[] could work altho it’s probably not what you’re looking for

[mortal hare]

that's what I currently do

but imagine many classes

and for each you have to create a new class or extend interface

smelly

[ivory sleet]

But else since types passed to type parameters aren’t necessarily retained during runtime it then becomes an issue for arrays hence why it isn’t possible

Yeah it’s smelly

[mortal hare]

well

wildcard type declaration works tho

new Foo<?>[50]

[ivory sleet]

Yes because then it accepts Foo<T> where T can be anything

So it effectively doesn’t impact anything in other words

[proper lark]

Anyone know a tnt tag plugin

[crisp steeple]

Generic<String>[] arr = (Generic<String>[]) new Generic[5]; ?

[proper lark]

Do you?

[uneven fiber]

Yo. I'm trying to create a command where it saves a message from the player, for example: /savemessage Hello my name is Steve. Any idea how to do this?

i tried this but it doesn't seem to work

[eternal oxide]

are you trying to store one message per player?

[uneven fiber]

yes

if they call the command again it resets to the new message

[eternal oxide]

then use a Map<UUID, String>

[uneven fiber]

Got it

[eternal oxide]

no need to loop over an array then

[uneven fiber]

ah so the for loop would be uneeded

[eternal oxide]

correct

[uneven fiber]

Ok

just wanted to clarify, the enderse array is for player and the msg array was used to store the players message

[humble tulip]

Hashmaps are also far more efficient

[uneven fiber]

I will try the map

never used one before so I was trying to do a different approach lol

[high ridge]

So has anyone gotten mojang mappings to work in gradle?

[eternal oxide]

Map<UUID, String> messages = new HashMap<>();

onCommand...
messages.put(event.getPlayer().getUniqueId(), event.getMessage());```

However, you would be better creating an actual command and not using the preprocess event

[uneven fiber]

let me send you a picture of my whole class

[eternal oxide]

?paste

[undone axle]

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

[uneven fiber]

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

[eternal oxide]

yep, don;t use the preprocess event at all

[uneven fiber]

what would you suggest then?

[eternal oxide]

so the code would be something like```java
Map<UUID, String> messages = new HashMap<>();

onCommand...
if (sender instanceof Player player) {
if (args.length > 0) {
messages.put(player.getUniqueId(), String.join(" ", args));
return true;
}
sysout(player.getName() + " : " + messages.getOrDefault(player.getUniqueId(), "No message stored!")
return true;
}```

[uneven fiber]

what does .put do?

[eternal oxide]

that would allow you to use the same command to store or retrieve a message

put adds am entry in the Map

[uneven fiber]

so thats essentially what stores the messages into the hash map

[eternal oxide]

So it stores teh message under teh players UUID

[uneven fiber]

kind of like .add for an arraylist

[uneven fiber]

Ok

So I would'nt even need to use an event handler!

interesting

[eternal oxide]

no

just the command

if you enter teh command with no text after it will show you the stored message

[uneven fiber]

awesome

thats what .getorDefault does

[uneven fiber]

sorry not directed towards this message

[eternal oxide]

If there is a message stored for that player it will fetch it, or if none it will add the no message message

[uneven fiber]

saying that if nothing was stored and nothing was put in then default is called

[uneven fiber]

yeah

[eternal oxide]

getOrDefault is nice to prevent null errors

[uneven fiber]

what does String.join do?

[humble tulip]

Have a guess

[uneven fiber]

lol fair

[eternal oxide]

builds a single string of all the args with a space between each

[uneven fiber]

yah

[naive loom]

would any know how to fix when you teleport two players a world the one player can't see one and the other one can see the other one? (i don't know how to explain it one, but it's like as one of the players have invisiblity in one of the mc window but the other mc window sees the other play perfectly fine.)

[eternal oxide]

Is the world loaded before you teleport?

[humble tulip]

Player.setVisible()?

[uneven fiber]

I'm getting an error for the String.join part

its asking for character sequences.

[eternal oxide]

google it, I may have got it slightly wrong

[uneven fiber]

Ok got it

thank you for your help!

[eternal oxide]

yep I got it in reverse

[uneven fiber]

yeah just checked

space should go in the first param

[eternal oxide]

String.join(" ", args)

[uneven fiber]

👍

Hashmaps are useful lol

Need to learn more about them

[dusk flicker]

maps arrays sets

very useful indeed

[uneven fiber]

Is there a way I could have done this with arraylists

[eternal oxide]

yes, but not as easily

[uneven fiber]

Ok

[eternal oxide]

It would have been a nightmare to replace a message

and lots of looping to find the right entries

[uneven fiber]

I see

Hypothetically how would I go about storing the message tho?

would I need to use an event?

[eternal oxide]

this Map you can put straight into a FileConfiguration (config)

[uneven fiber]

Cool

yeah the whole reason I want to store this message is because i’m creating another command where when you call it it will display the saved message

and imma just extend the saved message class to it

[eternal oxide]

That code currently allows you to use just the command to see the message

[uneven fiber]

What do you mean by see

[eternal oxide]

the sysout line System.out.println

[uneven fiber]

oh ok

i changed that line so that it sends a message in the world

[eternal oxide]

if you just type the command with no message after it, it will show you whatever message is already stored

[uneven fiber]

oh awesome

well i slightly changed it so that it is player.sendMessafe instead of sysout

[eternal oxide]

yep, thats fine

[uneven fiber]

I guess it isn’t technically the world sending the message but whatever

[steep cove]

[steep cove]

In my build.gradle I have org.spigotmc:spigot-api:1.18.2-R0.1-SNAPSHOT and in my plugin.yml I have 1.18.2-R0.1-SNAPSHOT however my server says that's an unsupported API version, what exactly do I put here?

[eternal oxide]

1.18 api version

[steep cove]

So just 1.18

[eternal oxide]

yes

[steep cove]

ah

does the main have to be accurate too

[eternal oxide]

very much so

[steep cove]

then I have quite the nooby question to ask you

I don't know the whole me.x.x I keep seeing on forums. What is the pattern for that because I only know the directory of the main file

[eternal oxide]

it will be the package name + your main class name

whatever package you have at teh top of your main class

[steep cove]

So I have SpigotGradleProject > src > main > java > Main.java

So the java folder

[eternal oxide]

no

[steep cove]

Oh?

[ivory sleet]

you use packages to structure your classes, like directories with normal files

[eternal oxide]

look in your actual class file, at teh top, the very first line will say package me.

[ivory sleet]

There’s one main class in spigot, the one that extends JavaPlugin as you are aware of

[steep cove]

Oh then I've done something wrong because I don't have a package

I thought package was synonomous with folder

I may have had a contextual misunderstanding then

[eternal oxide]

it is, kind of

[ivory sleet]

They’re to some extent

Packages do have a deeper meaning than just being directories in Java, but for your sake that deeper meaning isn’t substantially important

[steep cove]

Oh I mean I'll probably end up learning about them soon

[ivory sleet]

Yeah

But anyway you usually have to create the package yourself

or well, packages

[steep cove]

I have more of a C-background and some python, not a huge Java background besides some small projects

[ivory sleet]

Right

[steep cove]

Would it be acceptable structure to create a package underneath that java folder then?

[ivory sleet]

Java introduces several principles that advocate splitting the code up into different packages with different classes

yes

Usually (assuming you still use gradle) you got the src/main/java

Your packages should be under that directory

[steep cove]

Yup in gradle

And all the .java classes will go in that package I presume

[ivory sleet]

Correct

there are of course classes with no package (in other words they are located directly under src/main/java) but for most part you wanna avoid doing that

[naive loom]

yeah, how can i make sure though? it says the world is loaded in the console

[dusk flicker]

you could just load it yourself

[naive loom]

it says it's being loaded

im loading it through a db and the world is actually here when im teleported

[eternal oxide]

loading through a db?

[steep cove]

I believe my plugin.yml is correct - but my server is still spitting out "Unsupported API version 1.18.2-R0.1" and I just updated it with BuildTools to latest. Again for reference my project directory looks like SpigotGradleProject > src > main > java > me.goodvibes > Main.java and the plugin.yml main reads as me.goodvibes.Main. For version, in my build.gradle I have org.spigotmc:spigot-api:1.18.2-R0.1-SNAPSHOT and my plugin.yml is api-version: 1.18

[eternal oxide]

you can;t have updated teh jar or you did not update teh plugin.yml

[steep cove]

I rebuilt the artifact & rebooted server to make sure but I will do that again

[ivory sleet]

Wait

Hold on

You use gradle + artifacts?

[eternal oxide]

open your plugin jar with any (7zip) and view its plugin.yml

um, yes gradle + artifacts spells boom

[ivory sleet]

[steep cove]

I take it that's improper. After reviewing the spigot page real quick yeah it looks like those are separate methods of doing things, I must have bled one page to another

[ivory sleet]

https://www.spigotmc.org/wiki/build-you-spigot-plugin-with-gradle-groovy/

I wrote this a while back

That shows you how to properly use gradle

[uneven fiber]

respect 💯

[steep cove]

I'm just built different, thank you for pointing that out. This just shows how unfamiliar I am with java & IntelliJ

[uneven fiber]

yo

question

why whenever I call this is always just defaults

[ivory sleet]

defaults?

[wise hill]

gradle? icky

[ivory sleet]

the defaultValue?

[uneven fiber]

like it always print the No message stores

yea

I think it has to do with my main method

[ivory sleet]

Oh that’s iirc called inlay hints or sth

It comes up whenever you pass a magic value to a function

A magic value is either this, or a number/boolean/string

[wise hill]

it's a null check iirc

[uneven fiber]

^

this is my save message class which im extending

[eternal oxide]

This doesn;t have any of the code to store the message

[ivory sleet]

oh that thing ye

You miss @NotNull for the parameters probably

[eternal oxide]

ah you seperated it to two commands

[uneven fiber]

yeah

[uneven fiber]

what i meant by this

[eternal oxide]

You are using different maps for storing and retrieving

[uneven fiber]

Am I?

[eternal oxide]

store is in yoru SaveMessage class

what store are you using when you broadcast?

[uneven fiber]

the same store from the savemessage class

i extended it

broadcast is subclass

[wise hill]

don't extend it just make the store static

[eternal oxide]

then make store static

[uneven fiber]

💯

oh duh lol my bad

otherwise that shit wont store !

[eternal oxide]

a static object only has one instance

[quaint mantle]

does the jvm pass this into methods even if they dont require it?

or are they just accessed through a load istore or something

[eternal oxide]

Not sure what you are asking

[steep cove]

Where does gradle make the .jar

[eternal oxide]

target folder

[steep cove]

I can't say I know where that is but after searching the entire directory there is no jar file being created

But I definitely followed that article to a T

[eternal oxide]

the target folder will be at teh same level as the src folder

[steep cove]

yeah there's nothing there

[ivory sleet]

It should be created in build/libs

[steep cove]

there is no libs folder, I'm definitely lost here I might revert back to the artifact method on a non-gradle project tbh

[ivory sleet]

Nonono

So did you follow the wiki I sent you?

[steep cove]

Yeah all the way

If it makes you feel better I'd rather stay on gradle but I definitely am drawing a blank here haha

If your DM's are open I could send screenshots of my stuff since I can't send them here, but like I'm lost lost

[ivory sleet]

Sure

[maiden acorn]

using a YamlConfiguration option to read a config file... is it not possible to .get("list.0.subkey") where 0 is the index of the list you want to pull?

[flat olive]

anybody know how to rewrite velocity of enderpearls whenever they are thrown - event?

basically what I mean is

when they touch a open fence gate, make it so people can pearl through open fence gates

basically tali pearls plugin

and like make it so people cant pearl glitch

refund pearl

[flat olive]

nvm ill figure it out myself

will be a journey

[humble tulip]

hm

[iron palm]

Hey everyone, im trying to extend EntityZombie but i can't since im getting an error

'x()' in 'net.minecraft.world.entity.EntityInsentient' clashes with 'x()' in 'net.minecraft.world.entity.EntityLiving'; attempting to use incompatible return type```
Im using spigot mapping 
https://paste.md-5.net/padobumofo.java

[lone flint]

I'm trying to add a metadata "role" to the player (runner, hunter, etc.) and im getting a null error which seems to be caused by this line from some debugging

        metadata = (MetadataValue) player.getMetadata("role");
```and i set it here ```java
        player.setMetadata("role", new FixedMetadataValue(plugin, role));
```and i have been unable to find any good resources regarding how to use and retrieve metadata

"role" is an enum btw

[manic furnace]

When I create a nbttagcompound, do have to set the uuid range? Or is there a chance that it is overwritten by another item?

[harsh totem]

How do I make an enderman be angry at players?

should I just use enderman.attack()?

[summer scroll]

I don't know much about metadata but you can take a look at pdc, it might be helpful.

[undone axle]

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

[summer scroll]

I think you need to use NMS for that.

[harsh totem]

what is NMS

[summer scroll]

https://www.spigotmc.org/threads/nms-tutorials-1-introduction-to-nms.204127/

[harsh totem]

i got it without nms

[summer scroll]

May I know how? I'm curious also.

I thought you need to actually modify the PathFinderGoals.

[harsh totem]

    public void MobAngry(EntitySpawnEvent event){
        if (event.getEntityType() == EntityType.ENDERMAN){
            Enderman enderman = (Enderman) event.getEntity();
            for (Player player: Bukkit.getOnlinePlayers()){
                enderman.setTarget(player);
            }
        }else if(event.getEntityType() == EntityType.ZOMBIFIED_PIGLIN){
            PigZombie pigman = (PigZombie) event.getEntity();
            for (Player player: Bukkit.getOnlinePlayers()){
                pigman.setTarget(player);
            }
        }
    }```

[summer scroll]

Ah, that's very useful, I wonder when it was added.

[harsh totem]

idk im kinda new

@summer scroll do you know how to make the enderman and piglin be angry even when the player dies?

because it works until the player dies and then they stop hunting him

[summer scroll]

Maybe you need to keep track of the Enderman and Piglin reference and set the target whenever player respawn.

[harsh totem]

so another event when player respawns?

[summer scroll]

Yeah, listen to that event and since you keep the reference of the Mob, you can just loop through the mobs and then set the target to the player.

[harsh totem]

ok

[maiden briar]

UPDATE scores s1 INNER JOIN (SELECT *, FIND_IN_SET(score, (SELECT GROUP_CONCAT(DISTINCT score ORDER BY score DESC) FROM scores WHERE ranked = 1)) AS rank FROM scores WHERE ranked = 1) s2 SET s1.previous_place = s2.rank"

This does nothing to my table? No error, just no value is changed

[manic furnace]

is ther a post player join event?

[maiden briar]

PlayerLoginEvent

[manic furnace]

Is there a event that is called after the join msg?

[maiden briar]

You want to change the joinmessage?

[manic furnace]

No i want to send something after the join msg

[maiden briar]

Then send it 1 tick after PlayerJoinEvent

[manic furnace]

ok thanks

[iron palm]

how can i run buildtools with mojang mappings?

[chrome beacon]

--remapped

[iron palm]

oh

thanks

[maiden briar]

SELECT *, FIND_IN_SET(score, (SELECT GROUP_CONCAT(DISTINCT score ORDER BY score DESC) FROM scores WHERE ranked = 1)) AS rank FROM scores WHERE ranked = 1

This works, but I can't manage to save the rank result in a column named previous_place

[iron palm]

doesnt works...

java -jar BuildTools.jar --rev 1.18.2 --remapped 
pause```

oh worked

thanks

[harsh totem]

it there a way in InventoryClickEvent to get the inventory after the click?

because event.getClickedInventory() returns the inventory before the click

[summer scroll]

All cancellable event will occur before the actual event happen.

[harsh totem]

ok so is there a way to get the inventory after the click?

[summer scroll]

I feel like this is an xy problem, can you tell us what you are trying to achieve?

[harsh totem]

check if a player equips armor

This is what I have @EventHandler public void ArmorChange(InventoryClickEvent event){ if (event.getClickedInventory() instanceof PlayerInventory){ Player player = (Player) event.getWhoClicked(); if (IsArmor(player)){ for (Entity entity: player.getWorld().getEntities()){ if (entity.getType() == EntityType.ZOMBIFIED_PIGLIN){ PigZombie pigman = (PigZombie) entity; pigman.setTarget(player); } else if (entity.getType() == EntityType.ENDERMAN) { Enderman enderman = (Enderman) entity; enderman.setTarget(player); } } } } }

IsArmor(player) returns if the player wears armor

[earnest forum]

just check if the player clicked on an armour slot?

[summer scroll]

You can either delay it by 2-3 ticks, or you can check If player is about to wear the armor by getting the item on the cursor.

[harsh totem]

and if he unequipped the armor?

[earnest forum]

check if the slot isnt null after

[harsh totem]

so I need to schedule a delay of 2 ticks?

[terse ore]

How can I get the "targeted" block of a player

How could I get the location of that spruce log?

[chrome beacon]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/LivingEntity.html#getTargetBlockExact(int,org.bukkit.FluidCollisionMode)

[iron palm]

what should i add after that in pom.xml?
Currently i have xml <dependency> <groupId>org.spigotmc</groupId> <artifactId>spigot</artifactId> <version>1.18.2-R0.1-SNAPSHOT</version> </dependency>
should i add something else too that applies the mojang mappings?

Nevermind I think I found it

[peak jetty]

hi how can i add cooldowns to my playermoveevent? i want it so when a player walks on COAL_ORE it gives the player RABBIT_FOOT but i want there to be a cooldown or 30 seconds so before the 30 seconds end, if the player wanks on the block again they wont get the RABBIT_FOOT

    @EventHandler
    public void onPlayerMove(PlayerMoveEvent event) {
        if(event.getTo().getBlock().getRelative(BlockFace.DOWN).getType() == Material.COAL_ORE) {
            Player player = (Player) event;
            player.getInventory().addItem(new ItemStack(Material.RABBIT_FOOT));
        }
    }
}```

[earnest forum]

use UUID if you want it to work while the player's offline

[terse raven]

https://www.spigotmc.org/wiki/feature-command-cooldowns/

[peak jetty]

how would i use that with my playermoveevent?

[terse raven]

just read the wiki entry first and ask if you have anymore questions after that

[peak jetty]

alright thanks

@terse raven i have imported and created all i needed but now how can i implement this:

    @Override
    public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
        //Player only command
        if(sender instanceof Player){
            Player p = (Player) sender;
            int timeLeft = cooldownManager.getCooldown(p.getUniqueId());
            //If the cooldown has expired
            if(timeLeft == 0){
                //Use the feature
                p.sendMessage(ChatColor.GREEN + "Feature used!");
                //Start the countdown task
                cooldownManager.setCooldown(p.getUniqueId(), CooldownManager.DEFAULT_COOLDOWN);
                new BukkitRunnable() {
                    @Override
                    public void run() {
                        int timeLeft = cooldownManager.getCooldown(p.getUniqueId());
                        cooldownManager.setCooldown(p.getUniqueId(), --timeLeft);
                        if(timeLeft == 0){
                            this.cancel();
                        }
                    }
                }.runTaskTimer(this.plugin, 20, 20);

            }else{
                //Hasn't expired yet, shows how many seconds left until it does
                p.sendMessage(ChatColor.RED.toString() + timeLeft + " seconds before you can use this feature again.");
            }
        }else{
            sender.sendMessage("Player-only command");
        }

        return true;
    }

}```
into my code:
```java
    @EventHandler
    public void onPlayerMove(PlayerMoveEvent event) {
        if(event.getTo().getBlock().getRelative(BlockFace.DOWN).getType() == Material.COAL_ORE) {
            Player player = (Player) event;
            player.getInventory().addItem(new ItemStack(Material.RABBIT_FOOT));
        }
    }
}```

[terse ore]

Why I am duping the sponge?

When I place a sponge I get 1 extra

Before placing it, after placing it

[kindred valley]

What is your purpose

[terse ore]

Infinite sponge

[kindred valley]

Check if slot is not null

[terse ore]

Why that?

[kindred valley]

Are you getting another copy of sponge after placing it again?

[terse ore]

yeah

[kindred valley]

Because if slot has one than it wont be added again

[terse ore]

but the player can have more than 1 sponge

[kindred valley]

Umm i did not get the problem here

[terse ore]

x2

I am really confused

[kindred valley]

Can u explain your whole purpose

Physically

[terse ore]

wdym by physically

[kindred valley]

I mean what do you expect after placing a block

[terse ore]

I just want to make an infinite sponge, that when you place it you re-obtain it for using it again

[kindred valley]

So the problem is it is giving a copy of it right?

[terse ore]

yeah

[kindred valley]

If you check that if the slot is null, cant you control adding a new one?

Or check if its "Air"

[terse ore]

let me try smt

[peak jetty]

hello, would this code work?

    @EventHandler
    public void onPlayerMove(PlayerMoveEvent event) {
        Player player = (Player) event;
        int timeLeft = cooldownManager.getCooldown(player.getUniqueId());
        if(timeLeft == 0) {
            if(event.getTo().getBlock().getRelative(BlockFace.DOWN).getType() == Material.COAL_ORE) {
                player.getInventory().addItem(new ItemStack(Material.RABBIT_FOOT));
                player.sendMessage(ChatColor.GOLD + "10 Coins Earned!");
                cooldownManager.setCooldown(player.getUniqueId(), CooldownManager.DEFAULT_COOLDOWN);
                new BukkitRunnable() {
                    @Override
                    public void run() {
                        int timeLeft = cooldownManager.getCooldown(player.getUniqueId());
                        cooldownManager.setCooldown(player.getUniqueId(), --timeLeft);
                        if(timeLeft == 0){
                            this.cancel();
                        }
                    }
                }.runTaskTimer(this.plugin, 20, 20);
            }
        } else {
            player.sendMessage(ChatColor.GREEN + "You can get coins again in " + ChatColor.GOLD + ChatColor.GREEN + " seconds!");
        }
    }
}```

[kindred valley]

try?

[peak jetty]

💀

[terse ore]

Fixed it @kindred valley

[terse raven]

It probably fires twice once for main hand and once for offhand or something

[terse ore]

    @EventHandler
    public void blockPlaceEvent(BlockPlaceEvent event) {
        ItemStack item = event.getItemInHand();

        if (item.getType() == Material.SPONGE) {
            if (item.getItemMeta().getCustomModelData() == 302) {
                Player player = event.getPlayer();
                BukkitScheduler scheduler = Bukkit.getScheduler();
                scheduler.runTaskLater(Neo.getInstance(), () -> {
                    event.getBlock().getLocation().getBlock().setType(Material.AIR);
                    ItemStack sponge = new ItemStack(Material.SPONGE, 1);
                    ItemMeta itemMeta = sponge.getItemMeta();

                    itemMeta.setDisplayName(Data.color("&eEsponja Infinita"));
                    itemMeta.setCustomModelData(302);
                    sponge.setItemMeta(itemMeta);

                    player.getInventory().addItem(sponge);
                }, 1L);
            }

you are calling a method that does not exist

could you send us the corresponding lines?

give em flying

[hardy raven]

Is there any way to listen for packets with NMS?

[terse raven]

could you send us the PlutoCraftParkourRun class?

[peak jetty]

here:

        }
    }

thats everything in my class

[quiet ice]

You must have a no-args constructor

[terse raven]

            @Override
            public void channelRead(ChannelHandlerContext ctx, Object msg) throws Exception {
                super.channelRead(ctx, msg);
            }

            @Override
            public void write(ChannelHandlerContext ctx, Object object, ChannelPromise promise) throws Exception {
                if (object instanceof ClientboundBlockDestructionPacket) {
                    ClientboundBlockDestructionPacket packet = (ClientboundBlockDestructionPacket) object;
                    //if (packet.getId() != player.getEntityId()) return;
                    player.sendMessage("§a§l[BananaPrison] §f§lProgress: §e§l" + packet.getProgress()*10 + "%");
                    //if (packet.getProgress() == 0) return;
                }
                super.write(ctx, object, promise);
            }

        });


((CraftPlayer) player).getHandle().connection.connection.channel.pipeline().remove(player.getName());```

[peak jetty]

@terse raven

[quiet ice]

You must have a no-args constructor

[terse raven]

^

[peak jetty]

how do i do that?

[hardy raven]

Thanks

[quiet ice]

Remove your constructor?

[terse raven]

remove the public PlutoCraftParkourRun () function

[quiet ice]

The plugin instance is going to be this anyways

[kindred valley]

🥴 sorry

[terse raven]

and add a this.plugin = this in onEnable

[kindred valley]

There is much ways i guess

[terse raven]

but I'ma go now

[peak jetty]

wait so like this?

    @Override
    public void onEnable() {
        getLogger().info("PlutoCraftParkourRun Enabled");
        this.plugin = this;
    }```

[quiet ice]

remove your plugin variable, it is completely nonsense

[kindred valley]

Instance named plugin?

[quiet ice]

You PlutoCraftParkourRun instance is going to be your plugin instance, what you have here is a useless GETFIELD operation

[peak jetty]

private final Plugin plugin; <---- do i remove that?

sorry im new to this

[quiet ice]

Yeah

And any references to this field are replaced with this and any assignments need to be dropped

[terse ore]

How do I check if a player is not holding any item?

[quiet ice]

?jd.s

?jd-s smh

[undone axle]

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

[peak jetty]

@quiet ice i cant remove it tho because it caused a ton of errors

[quiet ice]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/inventory/PlayerInventory.html#getItemInMainHand()
https://hub.spigotmc.org/javadocs/spigot/org/bukkit/inventory/ItemStack.html#getType()
https://hub.spigotmc.org/javadocs/spigot/org/bukkit/Material.html#isAir()

[quiet ice]

You can

[peak jetty]

but it causes a lot of errors

[quiet ice]

As I say, you need to replace any this.plugin or plugin references with this

[iron palm]

Whats wrong with this code for spawning a npc?

        MinecraftServer minecraftServer = ((CraftServer) Bukkit.getServer()).getServer();
        Level level = ((CraftWorld) Objects.requireNonNull(e.getPlayer().getWorld())).getHandle();
        ServerPlayer player = new ServerPlayer(minecraftServer,level.getMinecraftWorld(),new GameProfile(UUID.randomUUID(),"Martin"));
        ServerPlayerConnection connection = ((CraftPlayer)e.getPlayer()).getHandle().connection;
        connection.send(new ClientboundPlayerInfoPacket(ClientboundPlayerInfoPacket.Action.ADD_PLAYER,player));
        connection.send(new ClientboundPlayerInfoPacket(ClientboundPlayerInfoPacket.Action.UPDATE_DISPLAY_NAME,player));

[peak jetty]

so like this?:
@quiet ice

public PlutoCraftParkourRun(Plugin plugin) {
    this = plugin;
}

[glossy venture]

its a problem in bukkit trying to initialize your plugin i think

[quiet ice]

DROP THE FUCKING ASSIGNMENTS

[glossy venture]

do you have a constructor defined with no arguments?

[peak jetty]

i dont know what that is im new

[quiet ice]

this cannot be assigned anyways

[glossy venture]

bro

[quiet ice]

JavaPlugin implements Plugin

[glossy venture]

the instance this is your plugin

bukkit cant create your plugin if you dont have a 0 args constructor\

[quiet ice]

as such any plugin is going to be this anyways

[glossy venture]

you need to have either no constructor or a 0 arg constructor

[quiet ice]

What idiotic tutorial did you read to come to the conclusion that you need such a constructor

[peak jetty]

ok done

[peak jetty]

the wiki that mja send me lol

[glossy venture]

tf

[peak jetty]

@quiet ice so my code should be ok now?

[glossy venture]

NO

drop the constructor

you dont need the constructor

[iron palm]

what are you trying to create?

[peak jetty]

what is the constructer?

[glossy venture]

only use a constructor if you need custom behaviour on instianiaton

[iron palm]

public PlutoCraftParkourRun() {
}
