depend: [NameTagAPI] # or however it's spelt

[stiff knot]

how do i check exactly how it's spelled?

i keep getting errors in console because i dont have the right plugin apparently

[tender shard]

/plugins

[stiff knot]

oh nvm i was messing with the formatting its loading now

im still getting the same error though

[hazy parrot]

And you added it in plugin yml

[stiff knot]

yeah

[hazy parrot]

And that namtagedit or whatever is loaded when you do /plugins

[stiff knot]

ya

this is just causing errors for some reason

[hazy parrot]

It's probably because it was not able to find plugin

[eternal oxide]

You are probably shading the plugin into yours

?paste your pom

[undone axle]

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

[stiff knot]

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

[eternal oxide]

yep add a provided scope

[stiff knot]

i do not know what that is

[eternal oxide]

<scope>provided</scope>

add to the nametagedit in your pom, the same as you have on spigot-api

[stiff knot]

alright

oh it works now

thanks ❤️

[river oracle]

does gradle support nested multi module projects yet

[remote swallow]

maybe?

[tender shard]

it would be very disappointing and surprising if it would NOT support that

[vivid skiff]

What is CraftPlayer#getHandle().b.a.k in the remapped mojang nms version?

[eternal oxide]

It should. It's mainly down to teh IDE if it supports nested

[river oracle]

ahh ok

[tender shard]

if you know from which version you took that "b.a.k" part, you should be able to check it yourself on the mappings website btw

I checked, but is a Bukkit class

[tender shard]

no

[remote swallow]

set it to spigot mappings

[tender shard]

CraftPlayer#getHandle() returns a ServerPlayer

[remote swallow]

intellij has been dying for random reasons recently

like multiple times this week its opened and then said "String isnt String" or other classes

yeah

[tender shard]

did you also start it through toolbox?

uninstall the manually installed version

then start the 2023 version

but yeah IJ starts to suck more every day

I also noticed that

e.g. CVS -> Share on Github -> all files are empty on github until you push stuff again

it's funny that the files are not completely empty though

[remote swallow]

cvs pharmacy?!?!?

[tender shard]

public class MyClass {
  private String something;
}

then after VCS -> Share on GitHub, on gh it looks like this

public class MyClass { }

like wtf lol

[vivid skiff]

Found it

[remote swallow]

have you had ij start to say a class isnt a class

[tender shard]

do you still ahve it open lol

[earnest lark]

im using a Listiner in my command and when i try to give it my main class for the plugin it says that it is not a enclosing class

[somber night]

im trying to add custom items that get consumed when used, but they get consumed in bulks of 5 instead of 1 by 1, why could that be? code (line 170 is where the onUse is): https://paste.md-5.net/bizezivude.java

[remote swallow]

i would deffo delete the mc dev plugin if someway to create a gradle project with specific build.gradle existed

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

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

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

[earnest lark]

yea thats what im doin

[hazy parrot]

Also why creating new anonymous listener every time command is executed

[earnest lark]

Pluggg is my main class

[hazy parrot]

Don't do that

[hazy parrot]

Pluggg.this doesn't mean anything

[earnest lark]

wait i got it

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

[earnest lark]

i thinl

[hazy parrot]

But don't register listeners like that dynamicly

[vivid skiff]

It isn't spawning the corpse, CODE https://pastebin.com/J4mh7kt9

[earnest lark]

how would you reccomend to do it

[hazy parrot]

Have 1 listener for all players and when player execute cmd put him in set or whatever

And if player is in set, execute logic

[earnest lark]

wait what

so like just have a thing of all the players then only they get through the Event

[hazy parrot]

What

[dawn spire]

What's a good way of storing worlds/groups of chunks to be persisted for skyblock-type worlds?

[hazy parrot]

I'm just saying you should have 1 onMove listener

Not add new one every time command is executed

As it can be really slow

[earnest lark]

yea i can understand that

but i want there to be a specified y lkevel that will teleport the player

and i dont know how else to do that

[remote swallow]

anyone know of an ij plugin that lets you create a gradle project with customiazble params? or just something that allows me to create a gradle project with a custom build.gradle

[echo basalt]

ah lovely

[tender shard]

you mean like maven archetypes?

[echo basalt]

schematics or .slime

you basically want something like my Cosmos project (WIP)

[remote swallow]

similar

[tender shard]

gradle only has gradle init but that only lets you choose project type (application, etc) and group id etc

[somber night]

how would i do that, i tried something and didnt work

[weak meteor]

Helpoooo

Code: ```java
@EventHandler
public void PlayerScoreboardEvent(PlayerJoinEvent event){
ScoreHelper helper = ScoreHelper.createScore(event.getPlayer());
YamlConfiguration config = new Scoreboard().getConfig();
ReplacePH placeholder = new ReplacePH();
if (event.getPlayer().hasPermission("naohcf.scoreboard.staff")){

        helper.setTitle(title);
        List<String>slots = PlaceholderAPI.setPlaceholders(event.getPlayer(), config.getStringList("staffScoreboard"));
        for (int i = 0; i < slots.size(); i++){
            String slot = slots.get(i);
            slot = placeholder.replaceAllPlaceholders(slot, event.getPlayer().getUniqueId(), event.getPlayer().toString());
            slots.set(i, slot);
        }
        helper.setSlotsFromList(slots);
    } else {

            slots.set(i, slot);
        }
        helper.setSlotsFromList(slots);
    }

}```

Config: ```yml

Default scoreboard

no permission needed

scoreboardTitle: "&b&lNaoHCF &7(Map I)"
scoreboard:

Staff scoreboard

Use naohcf.scoreboard.staff permission.

• "&7TPS: &b%tps%"
• "&7Vanish: %vanish%"
• "&7Gamemode: %gamemode%"
• "&7Players: %players%"
• ""
• "&7dsc.gg/voidciroo"

There's no Placeholder in the title btw...

Maybe its that?

[tender shard]

what's onJoinEvent line 64?

[weak meteor]

title = PlaceholderAPI.setPlaceholders(event.getPlayer(), title); // 64

[tender shard]

title is null

[weak meteor]

scoreboardTitle: "&b&lNaoHCF &7(Map I)"

it isnt

String title = config.getString("scoreboardTitle");

[tender shard]

print out the value of title

[weak meteor]

k

[small timber]

how can I listen to an anvil breaking? (running out of uses, not broken by a player)

[weak meteor]

never appears

maybe it is null

[tender shard]

so what was the value of "title" when you printed it out?

[weak meteor]

null

[tender shard]

there you go

[tender shard]

BlockChangeEvent

[weak meteor]

but what can i do then

[tender shard]

or sth like that

erm

[hollow birch]

Im still working on my block breaking thing and ive got here so far

            Pickaxe pickaxe = Utils.getPickaxeFromItemStack(player.getInventory().getItemInMainHand());
            Ore ore = main.getMiningEvent().getOreLocations().get(e.getBlock().getLocation());

            long speed = (long) pickaxe.getMiningSpeed() * ore.getHardness();
            @Override
            public void run() {
                e.getPlayer().sendMessage(String.valueOf(speed));
                if (!blockProgress.containsKey(e.getBlock())) {
                    blockProgress.put(e.getBlock(), 0L);
                }
                blockProgress.replace(e.getBlock(), blockProgress.get(e.getBlock()) + (speed / 10));
                player.sendBlockDamage(e.getBlock().getLocation(), blockProgress.get(e.getBlock()) / 10f);


                if (blockProgress.get(e.getBlock()) < 0L || blockProgress.get(e.getBlock()) >= 9) {
                    Bukkit.getPluginManager().callEvent(new BlockBreakEvent(e.getBlock(), player));
                    blockProgress.remove(e.getBlock());
                    this.cancel();
                }
            }
        }.runTaskTimer(main, 0L, 1L);```

I dont know why it only works when speed is 10 and not when its 5

[small timber]

that isn't a thing

entitychangeblockevent?

[mortal hare]

what a great addon

[tender shard]

lemme check craftbukkit's code

[mortal hare]

HighlightBracketPair for Intellij highlights brackets of the selected scope

so you can tell easily if your code is within the scope you're looking to have

[hazy parrot]

Doesn't intellij do that by default?

[mortal hare]

Sublime had something like this

[weak meteor]

now it prints out

[mortal hare]

kinda it does, but you need to select the bracket

[weak meteor]

but:

[mortal hare]

with this you can click anywhere in the scope block

and it will highlight

[weak meteor]

now the error is mine

k

[mortal hare]

the brackets

[hazy parrot]

Oh cool

[mortal hare]

it even works for function arguments

and array init lists too

[tender shard]

i guess the only proper solution is to listen to ClientboundLevelEventPackets being sent

[tender shard]

what's replaceph line 59?

[weak meteor]

nah

[small timber]

nah 💀

[weak meteor]

just fixed

it was a replace thing i removed from config

lol

[tender shard]

there is no normal event called

I checked the NMS source code

[weak meteor]

Now

the join event

doesnt give a error

but now i dont see scoreboard

im using this resource

https://www.spigotmc.org/threads/create-scoreboards-in-a-simple-way.272337/

and im creating the scoreboard

[small timber]

well fuck that

if there's one thing im not in the mood for it's packets

[weak meteor]

nvm

it worked

[tender shard]

you could ofc also just listen to InventoryClickEvent, check if the clicked slot is the result thing of an anvil, then wait a tick and check if the anvil is now gone

[mortal hare]

such a shame this doesnt work on Clion

[tender shard]

although ofc it might also be that a player has broke the anvil in the same tick as someone used it

but I guess that's pretty rare. and to prevent that you could also listn to BlockBraekEvent

[mortal hare]

well it kinda does work on clion but not exactly like on intellij i showed in this picture

[earnest lark]

im using Bukkit.getScheduler().runTaskTimer but i cant seem to throw the main class for the first paramater

[remote swallow]

you have to pass an instance

[earnest lark]

how bc i am stumped

[remote swallow]

?learnjava

[undone axle]

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

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

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

[earnest lark]

i have passed the instance and it just issnt working

[remote swallow]

so give the code

[earnest lark]

oh forgot new

my b

i like going to bed and instantly falling into a dream

[hollow birch]

can someone help me out with this

[orchid trout]

print the block progress

[hollow birch]

counts up 0-9 for regular

stays at 0 for enchanted one

[wise mesa]

in acf how do I specify a player name as an argument

right now I have this

but when I run it the invitee is just the player who ran the command

[tender shard]

use String, and then @Completion("@players") or sth like that

[wise mesa]

ah

so are there certain types that can be passed in as an argument

or is it all only strings

[tender shard]

well String, int, etc ofc works. If you want to directly get actual class instances passed, you have to setup erm

whats it called again

[remote swallow]

you can pass most things, if its a custom class you have to setup a context handler iirc

[tender shard]

it's called a COmmand Context

https://github.com/aikar/commands/wiki/Command-Contexts

[remote swallow]

close enough

[tender shard]

https://github.com/aikar/commands/blob/master/bukkit/src/main/java/co/aikar/commands/BukkitCommandContexts.java here you can see the builtin ones for bukkit

Player should definitely work btw

[remote swallow]

it is a context handler

[tender shard]

for players you gotta use a flag

public void onCommand(Player sender, @Flag("other") Player target)

https://github.com/aikar/commands/wiki/Frequently-Asked-Questions#how-do-i-use-my-custom-sender-class

[wise mesa]

ah thank you

[tender shard]

Or just use OnlinePlayer

Player sender, OnlinePlayer theOtherPlayer

Easiest way ^

@wise mesa just use OnlinePlayer

[wise mesa]

thanks

[hollow birch]

could it maybe be since it isnt a multiple of 10?

[tender shard]

did you use 5, or 5f?

[hollow birch]

5

but the 10 isnt set to f either

its good practice to set them as floats but that wouldnt be the difference in one working vs another

[hollow birch]

ok so i kinda fixed it

only thing now is im using .runTaskTimer(main, 0L, Math.round(100f / speed));

that to calculate speed

and it looks really weird

[hollow birch]

it doesnt show the damage always

only when it updates

[hollow birch]

fixed it by sending the packet instead of sendBlockDamage(

[weak meteor]

Im developing a mini staff mode, how tf when you use /staff and disable it continue with the same inventory you had when you activate it?

i really dont know how to

[hollow birch]

save the inventory when they activate

and when they disable set their inventory to the saved one

[weak meteor]

thx

worked

theres no way w/o listening to packets see if a player has text displayed in their actionbar right?

[sullen marlin]

Compiling against new API running on old server

[dark arrow]

why i get an error here

        if(sender instanceof Player){
            Player player = (Player) sender;

        }
        return true;

    }
``` i remember is was a method

it says getLocation is not defined

[quaint mantle]

Lol , md_5 is here that cool ! xD

[river oracle]

💟 omg its md_5 please give me head pats!!!

[river oracle]

1. Please follow naming conventions for your classes
2. Player#getLocation() does exist make sure you have the proper imports etc you may need to restart your ide

[quaint mantle]

i use intellij idea and i use plugin but IDE is not give a error to me

[river oracle]

as md said compiling against new API running on an older server

so your API version isn't targeting 1.12.2

[quaint mantle]

i use java 1.12.2 because my java version is 8 xD

[river oracle]

update java

[quaint mantle]

i know but i not have time to update

xD

[river oracle]

it doesn't take that long

surely you have time to update java if you have time to code a plugin as well

[quaint mantle]

Lol , because is end of my project and i will to sleeping ...

[river oracle]

if you are too lazy just change your api version in your plugin

warning a bit of your code will probably break

I reccomend updating however

[quaint mantle]

ok , no problem so in new version is have this ? what version ?

[river oracle]

You should know your own server version...

1.12.2 is your server version 1.19.4 is latest

[quaint mantle]

1.19.1 is ok ?

[river oracle]

No just use 1.19.4

There's no reason not to

i am unable to know what went wrong

on chat it just says internal error

[quaint mantle]

hm

maybe send full class

and not half?

the command wont work

because u didnt do a constractur

between the main class and the testCommand class

so a singleton between them would solve the problem

as well register the command in plugin.yml , if you want u can either make commands work using asyncchatevent and change first char for example commands on .

[dark arrow]

i did register it

public class ScaredZombie extends Zombie {
    public ScaredZombie(Location location){
        super(EntityType.ZOMBIE , ((CraftWorld) location.getWorld()).getHandle());
        this.setPos(location.getX(),location.getY(),location.getZ());

    }

}
``` full class of the zombie

i dont think anything is wrong with command as when i changed it to send a message 'hello' it worked

there must be smething wrong with my zombie class

Create a thread in case the channel is already in use!

[quaint mantle]

i see

[slim wigeon]

I creating a farming rod like EpicFarming but more realistic that does not multiply items. I try to place/remove a item to/from its inventory, it does not do anything? Most of the time and I think my code is broke

[quaint mantle]

line 14 is ScaredZombie?

[dark arrow]

yah

[quaint mantle]

try it like this

[slim wigeon]

Wait, I see what is happening. Its nothing wrong with these 2 functions. Just forget about the gui, its more for player.getTargetBlock(). How do I get the end rod I use for the farming rod thru plants like WHEAT, CARROTS and all that you farm?

[quaint mantle]

public class ScaredZombie extends Zombie {
    public ScaredZombie(Location location){
        super(location.getWorld().spawnEntity(location, EntityType.ZOMBIE));
}
}

tell me if it works now

[slim wigeon]

I have this code``` Set<Material> farmSet = new HashSet<Material>(); farmSet.add(Material.AIR);
for( Material material : farmBlocks ) { farmSet.add(material); }

    Player player = (Player) event.getWhoClicked(); Block block = player.getTargetBlock(farmSet,10); FarmLib farmLib = new FarmLib();```

[quaint mantle]

x y problem please describe whats wrong..

about the api go thru docs

?docs

[quaint mantle]

does it work?

[slim wigeon]

It does not always detect the end rod (Farming Rod) when my cursor is right on it

[quaint mantle]

describe Farming Rod == ?

is this a new itemstack or something?

'spawnEntity(org.bukkit.Location, org.bukkit.entity.EntityType)' in 'org.bukkit.RegionAccessor' cannot be applied to '(org.bukkit.Location, net.minecraft.world.entity.EntityType<net.minecraft.world.entity.monster.Zombie>)'

[slim wigeon]

But its using the official API, player.getTargetBlock() is apart of the API. I searched everywhere for hours

[quaint mantle]

u just try to spawn custom mob?

thats your goal?

[dark arrow]

yah

[quaint mantle]

make the class abstract to not implement all the not nessacery shit

extend it as zombie

and make summon method in it

and later just call the method

later you can make a bit more advanced like modifing things for example depending on int level set hp * lvl..

[quaint mantle]

what IDE do u use?

[dark arrow]

intelliji diea

*idea

[quaint mantle]

weird it didnt force to implement all the methods the way you did it before

i tried rn and i didnt even let me compile lol without adding 3k lines of that shit

[dark arrow]

hm

nms packages always change so much , i tried using my last code but it due to so many changes it does not work

now i have to find more way to do the code , idk why do they make things so complicated

[rugged gust]

thats not my question it is players should able to execute command B when an admin executes command B. before admin executes command B players cannot access command A

[quaint mantle]

mojang 😆

[quaint mantle]

use a boolean

..

public field

[dark arrow]

oh , then you can set a public flag and when admin executes it it should set true

[quaint mantle]

an check if admin executed change it

[rugged gust]

yeah i got it thanks guys!

[quaint mantle]

and learn java at least... dont try to fly straight forwards those things are simple to do i see you can use your imagenattion

there so many ways to do it

for something static use yaml config to make it static so restarts wont affect it

else if its liike condom used only once per restart then keep it that way using an boolean

[dark arrow]

lol abuot to say that

[dark arrow]

almost done ,i forgot the method to add an entity to the world , what was that?

yah fresh entity

[slim wigeon]

Ok, I looked at the whole source code of EpicFarming. I cannot even find where they use InventoryClickEvent like how they get the end rod. I also joined their server and noticed I not allowed to ping anyone there or send PMs so its only here it seems. While I not trying to make the exect copy of EpicFarming, I like to access the farming rod (End Rod) from any angle. I had to disable access to farming rod while sneaking due to this issue

[quaint mantle]

its not related here

we wont help you with someone else resource API

[slim wigeon]

I can look at the farming rod (End Rod) and player.getTargetBlock() returns Material.AIR or Material.WATER while the bounding box of the farming rod is shown

[quaint mantle]

imma just ignore u legit x y problem

[severe folio]

for (int i = 0; i > gui.getSize(); i++) {

Shouldn't that be i < gui.getSize()

[quaint mantle]

true

since it never starts the loop

lmao thanks i wasnt able to notice that ;/

thanks alot KonijkiNoYami you cant imagine how much time i was staring thru it and not finding a realistic reason why it works like that

[slim wigeon]

So there is no way to get any block in view using spigot?

[quaint mantle]

wdym any block in view

there many ways

from player cross?

you can getDirection and do some math and check if block is air

till u hit non air

and then return the block

while loop

and do max distance so wont be infinity loop

[spare radish]

I am now trying to add a custom block. I have created these codes for that purpose.

CustomBlock class

import net.minecraft.world.level.block.Block;
import net.minecraft.world.level.block.state.BlockBehaviour;
import net.minecraft.world.level.material.Material;

public class CustomBlock extends Block {
    public CustomBlock() {

        super(BlockBehaviour.Properties.of(Material.STONE).strength(1.5F, 6.0F));

    }
}

CustomBlockRegistry class

package ponme.nonameplugin.blocks;

import net.minecraft.core.Holder;
import net.minecraft.core.MappedRegistry;
import net.minecraft.core.Registry;
import net.minecraft.core.registries.Registries;
import net.minecraft.resources.ResourceKey;
import net.minecraft.resources.ResourceLocation;
import net.minecraft.server.MinecraftServer;
import net.minecraft.world.level.biome.Biome;
import net.minecraft.world.level.block.Block;
import net.minecraft.world.level.block.state.BlockBehaviour;
import net.minecraft.world.level.material.Material;
import ponme.nonameplugin.biomes.OriginalBiomeBase;

import java.lang.reflect.Field;

public class CustomBlockRegistry {
    public static Holder<Block> addBlockTest() {

        ResourceKey<Block> newKey = ResourceKey.create(Registries.BLOCK, new ResourceLocation("ponme", "test_block"));

        MappedRegistry<Block> registry = OriginalBiomeBase.getRegistry(Registries.BLOCK);

        Holder<Block> holder = null;
        try {
            Class<?> registryMaterialsClass = Class.forName("net.minecraft.core.RegistryMaterials");
            for (Field field : registryMaterialsClass.getDeclaredFields()) {
                if (field.getType() == boolean.class) {
                    field.setAccessible(true);
                    field.setBoolean(registry, false);
                }
            }

            holder = registry.register(newKey,new CustomBlock(),com.mojang.serialization.Lifecycle.experimental());

            registry.freeze();

        } catch (ClassNotFoundException | IllegalAccessException e) {
            e.printStackTrace();
        }

        return holder;

    }
}

I used this CustomBlockRegistry and tried to add it with the onEnable method.
Then I get this error on startup.

java.lang.IllegalStateException: This registry can't create intrusive holders

[chrome beacon]

Why are you trying to register a block

The client will have no idea what it is

[spare radish]

I see.
When I added the custom biome, I thought I could do it because it worked the same way as this. Thank you.

[somber night]

im trying to add custom items that get consumed when used, but they get consumed in bulks of 5 instead of 1 by 1, why could that be? code (line 170 is where the consume code is): https://paste.md-5.net/orulaxojug.java
for whatever reason the item with the namespaced key "kick" only consumes one

[wet breach]

your math is flawed

nvm, your math is fine read it wrong, but your issue is actually quite simple

you have 5 if statements to check for custom items, if all 5 match, then it will reduce by 5 since all 5 statements reduce by 1

so to fix that, add a return statement

[somber night]

where would i add it?

[wet breach]

at the end of the block of code that did something, or re-organize your code in such a way where if it enters one of the if blocks and it doesn't exit out to move to another one

so, using if else for example

[somber night]

but it shouldnt move to another one, the namespaced keys are different on each if statement

[wet breach]

well, you have 5 if statements that remove items

and you said that items are being reduced in 5's

so seems like you need to check your items out then

or you didn't account if an item could have all 5

[wet breach]

items can have more then one namespaced key in their metadata

otherwise we wouldn't need a namespaced key 😉

but at least now you know why the problem is happening and can now work on resolving the issue or figuring out why more then one key is being assigned to the item if that isn't what is meant to happen

[somber night]

yeah, thanks

[icy beacon]

evidently, checking instanceof on a generic is not possible. what workaround could i use? or should i abolish the default method overall and let the dev do it?

[tardy delta]

pass in a class

or do T extends EntityEvent if it really can only be that

or make it a method to implement yes

[icy beacon]

i want to allow EntityEvent and PlayerEvent, because for some reason PlayerEvent doesn't extend EntityEvent

probably will just make it a method to implement

[tardy delta]

we learnt about interfaces in college this week

i nearly fell asleep 💀

[icy beacon]

bruh what college is that

[tardy delta]

idk learning basic java

still got 14/17 on my test 😳

[kind hatch]

I'm finding out the more and more I work on this interchangeable database storage system, the more complicated it gets. Is it normal for monolithic interfaces to have unused methods in some implementations?

[tardy delta]

wondering what i was doing again 😳

[grizzled oasis]

Class: https://sourceb.in/5NbTcSzGE4
Error: java.lang.ClassNotFoundException: javax.activation.UnsupportedDataTypeException

Runner:

BlendCameraAnimation animation = null;
                try {
                    animation = BlendCameraAnimation.parse(new File(AlixAPI.getInstance().getDataFolder(), "test.animation")); //Line where's the error is
                } catch (IOException e) {
                    throw new RuntimeException(e);
                }

                BlendCutscene cutscene = new BlendCutscene(animation, player.getLocation());
                cutscene.play(player);

[grizzled oasis]

im not sure where the error is, google reports the error only for sending emails

[tardy delta]

why are you throwing a UnsupportedDataTypeException

[grizzled oasis]

where?

[tardy delta]

line 84 in the code you sent

[grizzled oasis]

because the file is not a .animation and doesn't have a string at the start

but the file that i made im sure is the one who supports it

[tardy delta]

looks like you made it wrongly then

[tender shard]

just use a proper exception, e.g. IllegalArgumentException

[grizzled oasis]

but how can i fix this?

[tender shard]

just use a proper exception, e.g. IllegalArgumentException

[grizzled oasis]

ok, but thats not the main cause

[tender shard]

then send the full stacktrace, and it'll reveal what the cause is

[grizzled oasis]

i just send it, the full stack trace return to a section in https://sourceb.in/5NbTcSzGE4 line 83

[tender shard]

Where did you send the stacktrace?

[compact haven]

maybe instead of writing those ridiculous instructions, use a real programming language like our beloved Java

then you can’t forget what you’re doing because it’s verbose :)

[tardy delta]

you dare to challenge me hmm?

[compact haven]

dare

[grizzled oasis]

bro its not needed the stack trace litteraly the problem is there, in the stacktrace is not needed because it sends you there

[grizzled oasis]

with this error

[tender shard]

Ok good luck fixing it then

[kind hatch]

A NEW CHALLENGER APPROACHES!!!

[tardy delta]

me trying to figure out why i cant iterate over 0..2 💀

counter is supposed to go -2 -1 0 but it goes -1 0 -1 1 0 💀

[icy beacon]

feeling stupid today, how do I get the type of the generic?

[compact haven]

you can’t throw an UnsupportedDataTypeEzception because javax isn’t included by default in the jar, only at compile time. Same reason why you can’t use Pair and have to make your own

@grizzled oasis

[tardy delta]

you dont

[icy beacon]

ah, cool

[compact haven]

so instead of being lazy and just finding some random exception that’s named like what you want, make your own

[icy beacon]

perhaps i should review my approach and not use a generic

[compact haven]

like I do that myself sometimes, but seriously ? javax?

[tardy delta]

or maybe instanceof RegisterableTrigger<Whatever>?

[icy beacon]

what do you mean?

i should probably elaborate

[icy beacon]

i want to see if in this list there's already a RegistrableTrigger with its type matching the type of this new registrable trigger

so i don't know the generic type of neither

[tardy delta]

ah you dont

[icy beacon]

yep

i'll just not use a generic

[tardy delta]

or you have a class field

[icy beacon]

i don't really have a need for it tbh (generic)

not sure why i went with it lol

[compact haven]

you can do plenty of hacky shit

the answers to this question will do basically what you wanted for T instanceof : https://stackoverflow.com/questions/1901164/get-type-of-a-generic-parameter-in-java-with-reflection

kind of ironic that the answers to that SO post have literally nothing to do with the question though

[tardy delta]

damn my program was working but it was just me outputting twice

[compact haven]

what were you evrn coding, and in what

[tardy delta]

printing an array

[compact haven]

Were they JVM opcodes or something else?

[tardy delta]

made smth custom

[compact haven]

ah okay

[icy beacon]

design question: should I return silently or throw an exception?

[tardy delta]

but i thought why not implement the parsing and runtime in java 💀

it gotta be c++

[compact haven]

First mistake, but yk who cares

[tardy delta]

my c++ knowledge is shit so thats why

[compact haven]

good design is to throw an exception

[icy beacon]

or maybe even make a RegisterResponse enum

would that be better?

[compact haven]

definitely not that, an enum lmao

[tender shard]

is it supposed to happen that it gets tried to register it more than once? if no, throw an exception

[tardy delta]

streams 🥰

[compact haven]

throw an exception, it’s fine

just annoying to catch

[icy beacon]

i want to prevent the dev from registering it twice

[icy beacon]

alright

[compact haven]

since it’s not checked though I’ll be the first to ignore coding the catch ngl

[icy beacon]

wdym?

[compact haven]

it’s not a checked exception so you don’t need to code the catch, it’s not forced

[icy beacon]

oh like, do you mean that I should put it in the signature

[compact haven]

no definitely don’t

[icy beacon]

not sure what you mean by checked exception haha

[compact haven]

yeah that’s okay just ignore me

[icy beacon]

well you got me curious now

[compact haven]

a checked exception is something that’s in the method signature like: public void ignore() throws IOException. You NEED to use a throw/catch since IOException is a checked exception. IllegalArgumentException is not a checked exception, so you don’t need to write the throw catch, instead if it’s thrown then the program will exit

[icy beacon]

oh I see

yeah i got it ty

would it be a better practice to use a checked exception in this case?

[compact haven]

I don’t even know that you can

can you even put IllegalArgumentException in the throws line

[icy beacon]

i mean you probably can but is it useful

one ssec

yeah it's possible

[compact haven]

ah okay, yeah just don’t

no one enjoys writing try catch in Java

[icy beacon]

true haha

[compact haven]

just realized I’ve been saying throw catch, I’m so fucking tired

I’m going sleep

[icy beacon]

though i also wonder why you suggested to not use an enum

wouldn't that be easier to handle

just a switch

[compact haven]

that’s like returning an Integer where 0 is success and 1 is fail, it’s just not right

[icy beacon]

not sure i'm following, integers are magic values and enums are named

[compact haven]

the proper way to handle this problem is an exception, every API with registration uses exceptions to prevent double registries

What I’m saying is that it’s equally silly

[icy beacon]

alrighty, thanks a lot, i'll take your help into account and code my api with it in mind

[compact haven]

take inspiration from other libraries, just not ones predating dinosaurs, when doing that

gl

[icy beacon]

ty 🙂

[tardy delta]

hmm ye sql

[icy beacon]

lmao

dumb code language detector

it's clearly haskell

[tardy delta]

hmm my parser doesnt really want to work

trying to read from memory indexed by a register value but its like nah ill give you the register value instead

[rough drift]

nah that's python 💀

[tardy delta]

i thought it was javascript but it seems to be sql

hmm time to really not copy the c preprocessor

i somehow want to write this in rust but i dont know much rust 🤔

[onyx fjord]

hey lets say green chunk is the chunk im in, how can i get chunks marked as red?

[quiet ice]

Chunk X +/- 1
and
Chunk Z +/- 1

[night verge]

I'm trying to make the tool in player's hand change its value of "tooldurability" tag whenever the player break a block.
But nothing change eventually.
Take a item having 300 as its "tooldurability" at first for an example.
output test1 is 299
but output test2 is 300
Is there any wrong with my code?

@EventHandler
    public void ToolEffect(BlockBreakEvent event) {
        ItemStack tool = event.getPlayer().getInventory().getItemInMainHand();
        if (tool != null && tool.hasItemMeta() && tool.getItemMeta().getPersistentDataContainer().has(new NamespacedKey(plugin, "tooldurability"), PersistentDataType.INTEGER)) {
            ItemMeta item_meta = tool.getItemMeta();
            int durability = tool.getItemMeta().getPersistentDataContainer().get(new NamespacedKey(plugin, "tooldurability"), PersistentDataType.INTEGER) - 1;
            tool.getItemMeta().getPersistentDataContainer().remove(new NamespacedKey(plugin, "tooldurability"));
            tool.getItemMeta().getPersistentDataContainer().set(new NamespacedKey(plugin, "tooldurability"), PersistentDataType.INTEGER, durability);
            System.out.println(durability + "test1");
            System.out.println(tool.getItemMeta().getPersistentDataContainer().get(new NamespacedKey(plugin, "tooldurability" + "test2"), PersistentDataType.INTEGER));
            tool.setItemMeta(item_meta);
            event.getPlayer().getInventory().setItem(event.getPlayer().getInventory().getHeldItemSlot(), tool);
        }
    }

[tardy delta]

ever heard of variables

[tender shard]

you never change the itemmeta

all you do is change a clone of the itemmeta, then you set it back to the original, unchanged meta

instead of calling getItemMeta() all the item, use your already stored item_meta

[night verge]

It worked! Thank you so much.

[dark arrow]

i have created an entity class using nms , how can i spawn it ? by a command or event

[quaint mantle]

Using the prepare smithing event how can i make it so the current recipe yields no result

[chrome beacon]

set result to null

[tardy delta]

thats what she said

[chrome beacon]

You sure

[echo basalt]

lmao

[chrome beacon]

Why are you throwing out of memory error 💀

[echo basalt]

I wonder if I can make my scripting engine overflow somehow

I already handle stack overflows by copying over variables to a temp cache and dumping the stack

[tardy delta]

ofc they hide all the nice utility methods in some jdk.util package

not my code btw

[tardy delta]

just put your stack offheap

[echo basalt]

well

[tardy delta]

no more overflows

[echo basalt]

stackoverflows happened when I had a recursive script play for too long

so when I play a script, I copy the variables from this script to the other

and dump the stack

and then play it

[tardy delta]

lol

[tardy delta]

since when does an arraylist have an empty array by default

i dont see any ten

[tardy delta]

hmm

[wet breach]

minimum size of arrays to store anything is 2n-1

[zinc lintel]

i got a problem with my plugin,
If i join i can not take anything out of any inventory while only it needs to be turn off for the bangui

This is the code i used for it

[chrome beacon]

Don't compare inventories by their name

[zinc lintel]

this is how i learned it with kody simpson

how i betther do it then?

[wet breach]

compare the inventory objects

[zinc lintel]

how i do that?

[wet breach]

reason for not using the name is because someone could send a packet with the inventory name

do you not know what an object is?

[zinc lintel]

im in my learning fase

[grave sparrow]

the way I did it back in like 1.12 was I created a custom invholder and then I could just compare the invholder w that

[wet breach]

inventory inventory = new inventory ideally your custom inventory AKA gui

now hold a reference to it, maybe in your main class

anytime you come across an inventory compare the inventory objects

if its not yours they won't match

[zinc lintel]

i don't get it

[grave sparrow]

personally I’d say storing a reference to each inv is pretty taxing, take a look at this small plugin I made while I was learning: https://github.com/poilet66/BannerEdit

[wet breach]

then you really need to learn more about java

[grave sparrow]

obv you don’t need a custom class for each gui tho

[chrome beacon]

Storing a reference is fine

[wet breach]

while true, it is probably advised as it keeps it organized

[grave sparrow]

tomato tomato I guess, if you’re tryna improve performance though there’s no way that’s advantageous

[wet breach]

in what way?

I don't see how it wouldn't be optimal other then taking up a few more bytes of memory

otherwise it would be fine

[grave sparrow]

well it just doesn’t scale very well at all

[wet breach]

yes it does scale if you use classes to organize your stuff

in what way does it not scale?

[chrome beacon]

^

[grave sparrow]

what happens when you’re running like a 400 person server with each of them trying to interact with different inventories

[chrome beacon]

That's 400 things in a list or set

[wet breach]

there shouldn't be 400 copies of your inventory

[grave sparrow]

why wouldnt you try minimise the memory you’re consuming?

[chrome beacon]

Depends on the type of inventory

[wet breach]

because memory is cheap first off, and the amount of memory consumed is not as much as you think it is

[grave sparrow]

oh do you mean storing an instance of each type of gui rather than each open one?

[wet breach]

true, but since we are talking in general for gui's typically only need 1 copy

[wet breach]

yes

[grave sparrow]

that’s better, but does vary with the type of inventory

what if it’s like a randomised mini game or something

[wet breach]

as I said it isn't going to take up as much memory as you think it would

at most with 400 copies of an inventory, you are looking at anywhere between 100-200mb of memory

[chrome beacon]

Probably less

[wet breach]

probably

I was estimating at the extreme 😛

[grave sparrow]

wasted memory nonetheless no?

why wouldnt you try engineer it the best you can

[wet breach]

because that is a waste of time

if you want the best might as well just drop to asm only

nothing else

[grave sparrow]

lmao

[chrome beacon]

Keeping things in a set isn't going to take hundreds of mb

[wet breach]

but then your time for making something exponentially increases. So its a trade off. You shouldn't waste your time on micro-optimizations unless that is all you have left to do and it is needed.

[tardy delta]

lets just do that java stuff in c++ lol

[wet breach]

mmm yes with some opcodes as well

just wait till you learn how to utilize extensions

[tardy delta]

kinda sucks that you cant store values in c++ enums

[compact lily]

i want to summon lightning couple block in front of me, how do i do that?

there's ^ ^ ^ symbol in minecraft command whenever i want to summon thing on my eye level, but i dont know how in here

sry bad english 😭

[terse ore]

you could strike the lightning at the block the player is targeting

[young knoll]

Get the players look vector, normalize it so it has a length of one, then multiple it by how far you want the lightning to be in front

You can then add said vector to the players location

[tardy delta]

always fun when creating a new project and you dont know how you're gonna call it

[frail gale]

Does someone know how to get a superclass instance from a class?

For now I have gotten only the class, but without the instance

[hazy parrot]

With reflection?

[frail gale]

yes

[hazy parrot]

.newInstance or whatever

[frail gale]

yeah, but I need the instance of the superclass

I already have the instance of the base class, but I need the superclass instance

if I do that then I just get an empty new instance

I need the one from the base class provided

[hazy parrot]

Oh you have base

Just call getSuperclass lol

And call newInstance on it

[frail gale]

wouldn't this just make an empty new instance? Or use the one which is provided from the base class?

I need to just get one field from the super class

which field is declared on the base class

[hazy parrot]

Well it will create new instance

[hazy parrot]

Just get field from superclass

And call field.get(baseObject)

It should work

[frail gale]

I tried it

[somber night]

whats wrong with those lines

[frail gale]

No it throws a java.lang.NoSuchFieldException

[eternal oxide]

you are registering 5 listeners

you have ONE listener, register once

[somber night]

oooh

5 listeneres makes 5 items consume

im stupid

[hazy parrot]

can you show your code

[frail gale]

Sure

[stiff knot]

Does anyone have any information on how to create custom configuration files? I ideally want to have a file that saves a list of player warp locations which I can read and write to

[frail gale]

I can dm on how you can do this and explain it you?

[stiff knot]

yeah sounds good

[hazy parrot]

https://www.spigotmc.org/wiki/config-files/#using-custom-configurations

[frail gale]

Field[] anvilContainerFields = ReflectiveUtils.getPrivateFields(container.getClass().getSuperclass()); for(Field field : anvilContainerFields) { System.out.println(""); System.out.println("Field: " + field.getName()); System.out.println(ReflectiveUtils.getPrivateField(container, field.getName())); }

[hazy parrot]

dk what is ReflectiveUtils

Container obj = ...;
Class<?> superclass = obj.getClass().getSuperclass();
Field field = superclass.getDeclaredField("foo");
field.setAccessable(true);
Object bar = field.get(obj);

this should work

[frail gale]

my own util class for faster Reflection

[frail gale]

will try it in 1 second

[tardy delta]

varhandles 🥰

[frail gale]

aren't you some type of magician? I literally tried that before and it didn't work, but right now it just worked, WHAT?

[hazy parrot]

idk what your utils are, but it looks like according to this line ReflectiveUtils.getPrivateField(container, field.getName()) that you are just trying to get field from subclass again by name

and that wouldn't really work

[frail gale]

yes you're right I need to do some tweaking a little bit. They work perfectly for normal classes and instances, but not for subclasses

[hazy parrot]

glad it worked 👍

[tender shard]

IJ drunk again

(and yes, I know the method calls itself, it's still bullshit to say that it's unused)

[eternal oxide]

not surprised its confused with an infinite loop.

[frail gale]

Yeah thank you very much! Right now I can do some NMS stuff

[wet breach]

intellisense can only do so much

[somber night]

how can i add explosion power to a fireball?

[rare rover]

Um, what would I put as the contracts with getPlayer() and all that ik that's wrong but it's not new nor fail? Would it be this? But it ain't returning the interface class https://github.com/Outspending/MobCore/blob/main/mobcore-api/src/main/java/org/mobgens/PlayerGenerator.java

Ig I could just remove the contract

how to get an EventPriority from a String in bungeecordApi?

[obsidian plinth]

whos a nerd who can help me rq?

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.

[steady wasp]

how i can set ItemStack nbt?

[inner mauve]

Im having trouble with external inventories/commands. Im getting these errors, the first is the /ec command(not opening) and the second is a different plugin for a vault plugin(null inventory screen/no gui access)

[quaint mantle]

Depend NBT API

[ivory sleet]

or use nms

or even better, pdc :)

[hasty prawn]

I mean it tells you that inventory is null, so whatever you're trying to open is null

Hard to really point you to a direct problem without seeing the code

[inner mauve]

where do i see the code for it, ive looked and I have no idea where im looking

[hasty prawn]

./ec command as in the /enderchest command from EssentialsX?

[inner mauve]

yes

[hasty prawn]

You might just have to take that up with them specifically

Just make sure your version is right

[obsidian plinth]

ok i really need help lol who can vc with me semi soon.

[inner mauve]

im sorry im dumb, is the other one something that is a spigot

[hasty prawn]

The second one just looks like the name of the inventory is "nul"

[inner mauve]

it also just has me take things out of it, instead of opening a new gui

its a player vault plugin

[hasty prawn]

Same thing then, try the plugin author, they'll have a way better idea what's going wrong.

[inner mauve]

alright thank you

im horrible at this stuff

[steady wasp]

player.getInventory().setItem(itemSlot, CraftItemStack.asBukkitCopy(net.minecraft.server.v1_7_R4.ItemStack.createStack((NBTTagCompound) MojangsonParser.parse(tag))));
why this not works?

item... immediately removes from inventory after changing nbt

[tardy delta]

this is fun

not cry when i have more than 16 of them

[worldly ingot]

If I'm not mistaken (and honestly I might be), you can do this

enum OpCode : uint8_t {
    HLT = 0x00,
    MOV,
    ADD,
    SUB,
    MUL,
    DIV,
    INC,
    IN,
    OUT,
    JMP,
    JP, // 0x0A
    JPZ = 0x0A,
    JNE,
    PD
}

[tardy delta]

hmm?

[worldly ingot]

The following constants will just increment

[quiet ice]

Two opcodes have the same value

[tardy delta]

ye

[worldly ingot]

Yeah, that's why I set JPZ to 0x0A

[tardy delta]

ah bruh cant even count in hex

[worldly ingot]

I'm like 40% sure you can do it twice

[quiet ice]

I completely disregarded that autoincrement thing

[tardy delta]

what have i been doing in college

kinda intresting approach to go from java to c++

cant even store data in an enum here so no idea how ill get a functional interface in there

a class ig

[worldly ingot]

You don't, yeah

enums are very primitive in C++

[quiet ice]

How do you have two projects opened at the same time in IntelliJ?

[worldly ingot]

What you're doing with an enum in C++ is nothing more than restricting a set of numerical values

[worldly ingot]

Two instances of IJ I think

[quiet ice]

Oh my god...

[tardy delta]

ij and clion

[worldly ingot]

[quiet ice]

Yep I'm out of there.

[tardy delta]

dont ask me why bruh

you should've seen alex' taskbar

[worldly ingot]

fwiw I suppose IJ can dedicate more resources to just a single project as opposed to Eclipse's workspace, but even still, I close like most of my projects if I'm not actively working on them

[tardy delta]

weak

saying i wouldve spent all the ram on my old pc already 💀

[quiet ice]

I upgraded to 32 Gb a year ago.
It was much needed - no idea how I survived with 16 Gb

[worldly ingot]

I need an upgrade bad

[tardy delta]

16 gigs

uhh

[round finch]

16 weak

[tardy delta]

its a laptop though

it already costed enough

[round finch]

oh shet laptop hardware expensive thb

[tardy delta]

and my battery somehow broke

[chrome beacon]

I'm starting to need more ram since everything is chrome in disguise

[quiet ice]

I mainly need ram to counteract the memory leaks present in large minecraft modpacks

[tardy delta]

ye firefox is chrome in disguise

idk why i even switched, probably because of the crashes

[tardy delta]

that too basically

[quiet ice]

I have no idea how people manage to make java use 20 Gb of RAM even with -Xmx9G in the first place to be entirely honest

Though the last few days I've spent on just fixing bugs on a single medium-sized mod and sometimes I question the sanity of mod devs

[tardy delta]

hmm lets just make my enum a struct and put some constants of it in a cpp file

[quiet ice]

You don't you use a function pointer array?

[tardy delta]

chatgpt told me about that, i was using a std::function before

[quiet ice]

So you map each opcode to an index on that array and here you have your "functional interfaces" (completely disregarding that those are not functional interfaces)

[tardy delta]

well it said smth like: have a struct with your data and a function pointer, then have a map to map a hex value to that struct

[quiet ice]

I'd just use a global array

[tardy delta]

actually lets use a simple array

[obsidian plinth]

anyone wanna hop in a vc rq and help me debug something

[quiet ice]

Chances are we don't need to be in VC for that

[obsidian plinth]

100% do

[tardy delta]

debug what

say that first

[obsidian plinth]

my turn switching method is broken for armourstands only but it says its working with the debug

so it calls the mthod right but doesnt allow the other player to do their move/turn

[quiet ice]

Then just paste the method

Also what is "the debug"

[obsidian plinth]

the method works for other moves

just not this one

all call it the same

    public void switchTurns(UUID playerUniqueId, UUID opponentUniqueId) {
        if (playerExtraTurns.getOrDefault(playerUniqueId, 0) > 0) {
            playerExtraTurns.put(playerUniqueId, playerExtraTurns.get(playerUniqueId) - 1);
            Bukkit.getLogger().log(Level.INFO, "Player " + playerUniqueId + " has extra turns. Not switching turns.");
        } else if (playerSkippedTurns.getOrDefault(opponentUniqueId, 0) > 0) {
            playerSkippedTurns.put(opponentUniqueId, playerSkippedTurns.get(opponentUniqueId) - 1);
            Bukkit.getLogger().log(Level.INFO, "Opponent " + opponentUniqueId + " has skipped turns. Not switching turns.");
        } else {
            currentTurn = opponentUniqueId;
            Bukkit.getLogger().log(Level.INFO, "Switched turn from player " + playerUniqueId + " to player " + opponentUniqueId);
        }
        playerUsedFireworks.put(playerUniqueId, 0);
        playerMoves.put(playerUniqueId, null);
        playerMoves.put(opponentUniqueId, null);

        // Inform players about the turn switch
        Player currentPlayer = Bukkit.getPlayer(playerUniqueId);
        Player opponentPlayer = Bukkit.getPlayer(opponentUniqueId);
        if (currentPlayer != null && opponentPlayer != null) {
            currentPlayer.sendMessage(ChatColor.YELLOW + "It's now " + opponentPlayer.getName() + "'s turn.");
            opponentPlayer.sendMessage(ChatColor.GREEN + "It's your turn!");
        }
    }

[tardy delta]

thats a lot of puts bruh

[obsidian plinth]

as i said vc would be 1000% easier

this isnt some simple thing

[tardy delta]

nah just clean up your code

[obsidian plinth]

this is clean for what it does

[tardy delta]

have a gameloop which handles everything

[obsidian plinth]

i remove one line and it breaks

[obsidian plinth]

breaks it

[quiet ice]

what line is it?

that breaks it?

[obsidian plinth]

Ok its either yes i can help or no i can not help

[quiet ice]

I mean I can help but I'd like to avoid vc

I've never seen a problem where I had to use vc to be entirely honest

[tardy delta]

german music on the background

that would be perfect

[obsidian plinth]

it only breaks for this move

it works for the rest

[quiet ice]

Nah, just https://www.youtube.com/watch?v=YEHyHQcYf-c

[obsidian plinth]

bc the rest rely on block places not entity place/spawn

[quiet ice]

Chances are some preconditions are not set

[tardy delta]

https://tenor.com/view/pepe-the-frog-dance-happy-meme-pixel-gif-17428498

coding music

[quiet ice]

You are missing return;s in your two if statements

[obsidian plinth]

that block works for every other move

[quiet ice]

actually, it's more complicated than that

[obsidian plinth]

imma just be lazy and make it think its a block im placeing when i place a armor stand.

[quiet ice]

regardless playerExtraTurns and playerSkippedTurns is a bit flawed

[obsidian plinth]

how so?

    public void addExtraTurn(UUID playerId) {
        int currentExtraTurns = playerExtraTurns.getOrDefault(playerId, 0);
        playerExtraTurns.put(playerId, currentExtraTurns + 1);
    }

    public void skipTurn(UUID playerId) {
        int currentSkippedTurns = playerSkippedTurns.getOrDefault(playerId, 0);
        playerSkippedTurns.put(playerId, currentSkippedTurns + 1);
    }

i mean that also works lol

the move that skips the opps next move works

[quiet ice]

if any of the two values are > 0 then the players are still reminded of the turn switch

Actually wtf how can this method work in the first place

[obsidian plinth]

Ok i go in i place a cake it goes to my opp i cant place summion drop anything my opp can. and it just works

so either u dont know what you are talking about or sum

bc it works lol

just having a problem with the entity swaping turns

[quiet ice]

The message that is sent always remains the same

Unless you swap out playerUniqueId and opponentUniqueId somewhere else

but at that point you could just not make use of currentTurn

[obsidian plinth]

ok explain to me how my code works for everything else but u are saying it doesnt?

i can go in and play a whole game only use block moves and it works

[quiet ice]

ugh fine.
I'll go to vc and see if you can explain it that way

[obsidian plinth]

Naw u clearly dont know tf ur talking about.

"doesnt work at all"

i just did the lazy thing and trick it into thinking the Armor stand was a block.

[quiet ice]

I am just talking with the info I know at the very moment

[obsidian plinth]

works the same

[quiet ice]

But if your switchTurns method ends up to be broken you'll remember me

No whining on that front

[tardy delta]

hmm smth like this ig

[obsidian plinth]

hasnt broke in 4 months

[quartz gull]

e

[obsidian plinth]

works fine for blocks.

[quiet ice]

AH I get it

but then you are using a very nonstandard form of flow-control

And the method name is called misleadingly

Should be onSwitchTurns

Or full enterprise-style name: informPlayerOnChangedTurnsOnPostSwitchTurns

[unborn sigil]

What?

[quiet ice]

Basically that enterprise-style name signifies three things

• Players are informed that their turns have changed
• Only called after turns have changed
• The method does not act a form of flow-control but rather purely informational

[crude cobalt]

Hi everybody, does anyone know why when I click on a block, the event happens twice
Code:

@EventHandler
    private void PlayerInteractEvent(PlayerInteractEvent playerInteractEvent){
        if(playerInteractEvent.getAction() == Action.RIGHT_CLICK_BLOCK){
            if(Objects.requireNonNull(playerInteractEvent.getClickedBlock()).getBlockData().getMaterial() == Material.CAMPFIRE){
                playerInteractEvent.getPlayer().sendMessage(ChatColor.GREEN + "campfire");
            }
        }
    }

[quiet ice]

?playerInteractEvent

smh

[remote swallow]

?interactevent

[undone axle]

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

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

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

[quiet ice]

really people

[remote swallow]

yeah

were too lazy

[crude cobalt]

Thanks

[idle iron]

I am having problems with this code because it runs for the attacker and for the victim, so it runs twice and causes bugs. I tried using the EntityDamageEvent but I couldn't find a way to check if the attacker is a player.

   public void onEntityDamageByEntity(EntityDamageByEntityEvent event) {
       if (event.getEntity() instanceof Player) {
           Player victim = (Player) event.getEntity();
           
           startCombat(victim);
           Bukkit.getLogger().info("victim " + victim);

       }
       if (event.getDamager() instanceof Player) {
           Player attacker = (Player) event.getDamager();
           
           startCombat(attacker);
           Bukkit.getLogger().info("attacker "+ attacker);
       }
   }```

[junior geyser]

I dont really understand what you mean. But if you want to check if the player, and the attacker are both players do

        if (event.getEntity() instanceof Player && event.getDamager() instanceof Player) {
            // Here the victim, and attacker are both players
        }

[tardy delta]

lol

[idle iron]

That's not my problem The problem is that when I hit something, this function gets run twice.

Or when I get hit

[junior geyser]

What function?

the startCombat fucntuion?

Yeah you are running it for the victim , and the attacker in your code

so thats twice

[idle iron]

My bad I meant the event happening twice.

one time because I hit the entity and one time because the entity got hit, I think I am not sure

[junior geyser]

Are you rgersting the event class twice?

[junior geyser]

Oh yeah that might happen

[unborn sigil]

Who are you and who invited me here?

[worldly ingot]

¯_(ツ)_/¯

You're on SpigotMC. Minecraft server modding

[unborn sigil]

Thanks

Who invited me here?

[quiet ice]

You should know

[idle iron]

Thanks for the help. I solved it I registered theEventHandler on my main class so it ran twice 😄

[quiet ice]

We do not know

[tardy delta]

does this looks good @quiet ice

[junior geyser]

Amazing!

[quiet ice]

oh god

[worldly ingot]

I mean this is like your 4th time asking this question

[tardy delta]

lets just say im new to c++

that doesnt count as an excuse but whatever

[quiet ice]

To be honest I have 0 experience with C++

But I wouldn't even dare to use C++ in any way similar to java

Well I'd probably just write plain C code at that point

[tardy delta]

hmm manually memory allocation, fun

[quiet ice]

Just don't use the new keyword

[worldly ingot]

Or if you do, delete it

[jagged bobcat]

Why write c when cpp is extension to c

[tardy delta]

last time i tried to delete a string literal

didnt really went that good

[jagged bobcat]

• cpp compiles to machine code still

[quiet ice]

CPP is OOP. That being said writing procedural code is back in fashion at the moment

Basically OOP is not seen as a bonus but rather as a detriment to some. I share that opinion when it comes to working at such a low level

[tardy delta]

classes dont feel low level at all

[hazy parrot]

Why would you use extern in cpp

It's basically considered bad pratcice

And not object oriented

[tardy delta]

idk im still figuring out stuff

[orchid trout]

when i tried to learn cpp i got bored after 3 days

[hazy parrot]

/shrug I have to learn it for uni

Player#hideEntity is deprecated, is there a different way?

[main barn]

i think my server has a memory leak, i have used spark to create a heap dump, and looked at it, but i have no clue what could be causing it? can anone help me?

[tardy delta]

hideEntity(Player, Plugin)

[sage dragon]

This method is also deprecated.

I don't want to hide players, but entities

[tardy delta]

wdym deprecated

[late sonnet]

the deprecated are hidePlayer but also i think the hidePlayer now use the hideEntity then its the same..

[tardy delta]

hmm

[sage dragon]

Weird, my IDE is complaining about it being depecrated 🤷

[late sonnet]

XD

[tardy delta]

what version u on?

[hazy parrot]

if i would have to guess i would say paper xd

[sage dragon]

I don't depend on paper though 🤔

[late sonnet]

oh i remember in what case is deprecated.. in olds build Deprecated was for "you dont need use this" and also "this method is draft-api or experimental then we advise"
in a few PR i make this use Experimental for make the difference

[worldly ingot]

hideEntity() was deprecated as draft API up until recently when we started using @Experimental instead

You can either update your API version or suppress the deprecation. That method isn't going anywhere

[remote swallow]

component pr when

[late sonnet]

for who manage how rebase things in spigot? xd

[worldly ingot]

I'll see if I can get the motivation to do it in May after my gf goes home

[frail gale]

Does someone know how I can change the holder of the inventory?

[remote swallow]

is she not canadian?

[sage dragon]

Okay, perfect. Now I just need to figure out why it doesn't hide the entity 🤔

[worldly ingot]

No

American

[remote swallow]

damn

chocos dating an outsider

[frail gale]

bump

[quiet ice]

bump what?

[frail gale]

How can I change the holder of an inventory?

[quiet ice]

in normal circumstances you can just open the inventory with the new owner

But it depends on what exactly you wish to accomplish

[frail gale]

the inventory is already created

so I can't create a new one

it's for Anvil

[quiet ice]

Just do player.openInventory(inv) or something

[frail gale]

this is not gonna change the holder

I need to change the holder

InventoryHolder

[remote swallow]

most likely need to create a new inv with that holder

[frail gale]

But I can't create a new one

[remote swallow]

why not

[quiet ice]

won't that change the holder?

?jd-s it's been ages since I touched that part of spigot though

[undone axle]

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

[frail gale]

because the inventory is created through NMS and then converted to Bukkit with a method which seems to not change the holder

[quiet ice]

Well I guess you can't change the holder

You shouldn't need a holder anyways - consider it an implementation detail

[frail gale]

Yeah, but it makes my event handlers much easier

[quaint mantle]

how can i open a bookpage in my gui and save the contents as a string when they click save thingy

[quiet ice]

I mean the extra logic that would be needed is only like 50 lines of code at the very most

[frail gale]

As far as I know it's possible.

[fluid finch]
