[wet breach]

Yeah well its a private hospital so they get to make the rules lmao

Public hospital would not even be able to charge that much

[icy beacon]

Let's say you were to suffer a cardiac emergency suddenly (e.g. cardiac arrest). How much would you be billed and how much would you end up paying? Just an approximate number

Particularly in your case with your insurance etc

[wet breach]

Depends, but you could easily expect $2k-$5k on the low end and no more then $10k

For me its free since i have the VA

If i used my jobs insurance i would probably only pay $500

[icy beacon]

And that's covered by insurance, right?

[wet breach]

A good majority yes. So as i said just before you replied i would probanly have to cover $500

General rule is your insurance will cover something like 70%-80% of the bill. The rest would be on you. Lowest you could expect or most is you are covering half but thats like dirt cheap insurance lmao

[icy beacon]

I see. That's kind of a relief then

Though I was browsing my brain and a topic of housing prices came up 😬😬

They are an atrocity across the entire world rn

[wet breach]

Most people are not ending up in the hospital either. So medical stuff is only a worry if you are a frequent flyer

[icy beacon]

But from what I know it's really prevalent in the US

[icy beacon]

Gotcha

[wet breach]

Housing prices vary wildly on state and where in that state lmao

[icy beacon]

How about yours?

[lilac dagger]

but not by much

[wet breach]

I currently pay $1,500 for a one bedroom apartment. Its like almost 900sq ft

And my utility bill is usually no more then $140

[lilac dagger]

that's nice

but buying is a different case

[icy beacon]

I'm struggling to visualize 900sq ft lol

[icy beacon]

Yeahhh

[tender shard]

83m^2

[lilac dagger]

the houses start at like 500k

[icy beacon]

Yeah I ran the converter but still didn't imagine much

[wet breach]

83.6 sq meter

Oh alex beat me

[tender shard]

just imagine a 83 meter long hallway that's 1 meter wide lol

[wet breach]

Lmao

[icy beacon]

Well that's long lmao

Well would 83sq meters be sustainable for, for example, a small party? Like idk 7 people celebrating new year and goofing

[tender shard]

sure

[lilac dagger]

of course

[icy beacon]

For some reason I find it hard to visualize 83 sq m sorry lol

[wet breach]

My apartment is almost a perfect square. 30ft x30ft

[icy beacon]

That's true

Well frostalf you have succeeded in breaking a thick layer of my bias xD

[wet breach]

9.1m x 9.1m

[lilac dagger]

i assume it has walls

[tender shard]

i just googled "80m^2 apartments" and this eg is one

[icy beacon]

Yo that's plenty of space

Nice

[wet breach]

Square footage in the US is measured by usable space not the overall dimensions of the four outer walls

[lilac dagger]

yes i know, we do the same here

i'm talking if your perfect square is separated by walls

[wet breach]

What does kind mean?

[lilac dagger]

like here

[wet breach]

Bedroom?

[lilac dagger]

bedroom has to of course

[tender shard]

child

[icy beacon]

Alex do you enjoy your life in Germany?

[wet breach]

Oh interesting

[tender shard]

it's pretty great imho lol

I'm just upset that carlos doesnt show up

[icy beacon]

Yeah I've heard some good things about life in Germany

[icy beacon]

Carlos?

[wet breach]

To be fair alex is rich like me

[icy beacon]

Flexing on us peasants xD

[tender shard]

some dude who shall fix my wall

[icy beacon]

Ah

That's very punctual of him

[wet breach]

Well better then you breaking doors in random hotels

[tender shard]

i was told "carlos shows up at 8am" and it's 8.15 now

[icy beacon]

Where is d o o r

[wet breach]

It broke

[tender shard]

there is no door

there used to be a normal wall

[icy beacon]

Ah yes, the most convenient door. No door

[wet breach]

But alex didnt break it this time.

[icy beacon]

European walls are no shit

They will not break at a punch of a fist xD

[tender shard]

the idea is to have a "walk through" kitchen with no walls

erm

no doors

[icy beacon]

Same actually

Living room to kitchen

[tall dragon]

your fist will ;d

[upper hazel]

ArrayDeque is it synchronized by bakkit?

or cannot be combined with bukkit task and asynchrony

I'm deleting the chunk if necessary

[gentle nexus]

if i want to start plugin dev
where should i start from ?

[lilac dagger]

write a simple plugin

[upper hazel]

for example rtp plugin

[lilac dagger]

you can see all forms of tutorials by search on youtube google duckduckgo

i don't know if rtp is the best

he'll end up tp into some chunk

[upper hazel]

simple rtp plugin

not one that uses a lot of math, but just a teleport

[minor junco]

Learning programming. In this case Java and/or Kotlin. You can learn while doing tutorials, but first you should learn the basics of Java. How to print something, what types are and how to initialize them, what inheritance is etc.

[gentle nexus]

ik a decent bit of java

i dont know kotlin tho

[minor junco]

Okay, then start reading docs and tutorials on how to create plugins and what there's to it

[minor junco]

U don't need Kotlin

[gentle nexus]

any useful links ?

[minor junco]

It's just another language that compiles to the JVM

[minor junco]

Let me search rq, I used a specific tutorial series back in the day but I don't think I'll find that

https://www.spigotmc.org/wiki/spigot-plugin-development/

Maybe this helps

[tender shard]

here's a small guide on how to setup a project with IJ + maven https://blog.jeff-media.com/how-to-create-your-first-minecraft-plugin-using-the-spigot-api-and-maven/

it doesnt explain the API though, only the project setup

[minor junco]

I mean we can assume when someone knows how to program on an intermediate level they'll understand the rough procedure on how to setup things. But this might be helpful in case you don't know. Tho, I think OP wanted to know the API specifics

[minor junco]

So may wanna try dis

[gentle nexus]

k ima look into it

i should use maven over gradle right ?

[fallen lily]

Well, preferably you would use gradle but since you don’t know the difference between the two, I would stick to maven lol

[chrome beacon]

Use what you're most comfortable with

if you've never worked with neither of them then start with maven

[tender shard]

i don't think so. many people know basic java but never heard of maven for example

[fallen lily]

javac go crazy

[wet breach]

That is because they dont bother learning build systems. One of the disadvantages of not having formal education in such things

[fallen lily]

Hey, minecraft didnt use a build system

[wet breach]

But now they know so hopefully they will take time to learn and research things

[wet breach]

Pretty sure it did

The common build system that most IDE's default to is the ant build system

Exception is eclipse they always done their own thing lol

[fallen lily]

Na he just yeeted jars in a libs folder and called it a day

[gentle nexus]

jdk version 17 for mc 1.20.4 ??

[fallen lily]

Manually added to compilation classpath

[fallen lily]

The same structure has remained to this day

.minecraft/libs

except they have been flattened down to include group, name & version sub-folders

[wet breach]

Java 17 is the minimum requirement for that version

[gentle nexus]

ill have to create a server to test my plugin right ?
is there any place where i can run a server for a short period of time for free ?

[remote swallow]

your own computer

[gentle nexus]

my pc isnt very strong

[glad prawn]

dont worry

[agile berry]

gguyys how to properly exclude meta-inf from jar in maven?

I believe

[icy beacon]

Sniped

[upper hazel]

what is the name of the antivirus jar plugins that 1 person created and posted on spigotmc

we talk with him

long time ago

[remote swallow]

optic?

[glad prawn]

cats

[upper hazel]

this name start with A

Ad... Aw somentihg like this

[remote swallow]

no clue then

the only antiviris i know of on spiot is made by optic

[upper hazel]

person say what this plugin should have been paid

[glad prawn]

bro are u ask the owner name or the plugin name

[upper hazel]

both

for find name

[remote swallow]

this? https://www.spigotmc.org/resources/spigot-anti-malware.64982/

[upper hazel]

like yes

[gentle nexus]

how strong does my server have to be ?

[chrome beacon]

A (mid range) CPU from the last 10 years is fine

I used to run Intellij + 2 clients + server on my i5 3470

[upper hazel]

how to put head in tab with skins in the license server

[lost matrix]

Send a player tab packet with a skin

[upper hazel]

why do some plugins overlap the heads on the tab?

without tab plugin heads exists

[lost matrix]

I dont know what that is supposed to mean even

[upper hazel]

why do some plugins remove the heads on the tab when enabled?

[chrome beacon]

If you're talking about flickering extra heads that could be because of plugins like Citizens

That's due to a limitation of Minecraft

The packets required to spawn an NPC with skins is the same as adding it to the tab

so what they do is add it and then remove it again

[upper hazel]

for example premium tab not show heads in tab in license server

[lost matrix]

In newer versions this doesnt happen anymore becuase you can make a client aware of another player without adding him to the tablist

[upper hazel]

you mean heads removed or tab plugin remove this

[lost matrix]

You gonna end up accidentally summoning a demon if you dont stop with that gibberish...

[upper hazel]

sorry I don't understand English well

[upper hazel]

What do you mean that now the tab plugin does not remove heads from the tab sheet?

[lost matrix]

I think i get what you mean.
What they do is fill the tablist with empty profiles.
No skin, no tab name.
After that you can simply update the tab entries.

You want to know how those empty slots are made, right?

[upper hazel]

I want to know how to make a plugin on a tab so as not to remove the head from the tab

[lost matrix]

https://tenor.com/view/bunny-wth-confused-huh-what-gif-17289999

[upper hazel]

soryy

like NOT premium tab

[lost matrix]

Idk what premim tab is

[chrome beacon]

Probably talking about an online mode server

still no idea what they're trying to do though

[upper hazel]

premium tab removes heads from the tab when using the plugin and I want to create my own so that it does not remove heads from the tab

[chrome beacon]

??

[upper hazel]

in online mode premiun tab plugin delete heads too

[chrome beacon]

so it's not online mode

No idea what premium tab is then

[upper hazel]

https://www.spigotmc.org/resources/tab-1-5-x-1-16-4-premium.83967/

or tabs plugins not remove heads?

[chrome beacon]

It shouldn't do that

if you're having issues ask their support

[upper hazel]

oh this mean someone lie me

[chrome beacon]

I mean it could be a setting

It's been a while since I last used it

[upper hazel]

how to make own plugin not affect the head in the list of tabs

[chrome beacon]

ask the tab support

[minor junco]

fairs

[ocean hollow]

        RayTraceResult rayTraceResult = player.getWorld().rayTraceEntities(getLocationInFront(player, 1.2), player.getLocation().getDirection().multiply(1), Bukkit.getViewDistance(), 1f);
        if(rayTraceResult == null) {
            Bukkit.broadcast(Component.text("RTR = null"));
            return;
        }

        Entity entity = rayTraceResult.getHitEntity();
        if(rayTraceResult.getHitEntity() == null) {
            Bukkit.broadcast(Component.text("entity = null"));
            return;
        }
        if(entity == player){
            Bukkit.broadcast(Component.text("entity = player"));
            return;
        }

        if(!(entity instanceof LivingEntity)){
            Bukkit.broadcast(Component.text("entity is not living"));
            return;
        }

        Bukkit.broadcast(Component.text(entity.getType().toString()));
        ((LivingEntity) entity).damage(damage);
    }```

```     private Location getLocationInFront(Player player, double distance) {
        Vector direction = player.getLocation().getDirection().normalize();
        Vector offset = direction.multiply(distance);

        Location locationInFront = player.getLocation().add(offset);

        return locationInFront;
    }``` i wrote this, but it doesn't work. the result of raytrace is player.  but player is looking on sheep, i was trying to add to location distance, so as not to count the player, but it didn't help

[eternal night]

You'll want the eye location

Additional, you also can just pass a predicate to the raytrace method and filter out the source player

[quaint mantle]

can u send packets async?

erm i will j test it

[eternal oxide]

yes

[gentle nexus]

do i need to make my command class in the same folder as my plugin class
or somewhere else ?

[chrome beacon]

it's up to you

[lost matrix]

Everything is arbitrary. You could write everything into a single file. Heck you could even write your entire project into a single line of code.
Its all a matter on how organized you want your code to be. And using multiple packages and classes will help a great deal with that.

[echo basalt]

In short I'd make a package for commands

[ocean hollow]

    public void fire(Player player, ItemStack item){
        playFireSound(player.getLocation());

        damageUsingRayTrace(player);

        if(item == null) return;
        if(item.getType() == Material.AIR) return;
        if(item.getType() != material) return;

        ItemMeta itemMeta = item.getItemMeta();
        itemMeta.setCustomModelData(fire[0]);
        int nowBullets = item.getItemMeta().getPersistentDataContainer().get(MoreBullets.WEAPON_BULLETS, PersistentDataType.INTEGER);
        item.getItemMeta().getPersistentDataContainer().set(MoreBullets.WEAPON_BULLETS, PersistentDataType.INTEGER, nowBullets-1);
        item.setItemMeta(itemMeta);

        Bukkit.broadcast(Component.text(item.getItemMeta().getPersistentDataContainer().get(MoreBullets.WEAPON_BULLETS, PersistentDataType.INTEGER)));
    }
``` why pdc is not updating

[young knoll]

Because you are calling item.getItemMeta each time

Which returns a copy

Use the ItemMeta instance you already have

[ocean hollow]

ohh, okay

[upper hazel]

in bukkit api exists event which check in which location or block the dropped item fell?

oh wait i find

[gentle nexus]

ok so like https://www.spigotmc.org/wiki/create-a-simple-command/ is this outdated ?

[lost matrix]

Nope, not outdated.

[twin venture]

Hi i have a question , how i can make it so when player do /link , it will give him the rank he have in game to the discord server the bot in?

i don't want to use extra 3rd plugin

[gentle nexus]

what have i done wrong then ?

[lost matrix]

There is honestly no ItemStack which cant be directly instantiated...
What ItemStack did you import?

[twin venture]

for now iam using JDA library

[gentle nexus]

whatever my ide told me
which is org.bukkit.inventory.ItemStack;

[lost matrix]

If you dont want JDA then you can use discords web api.
JDA is just a wrapper for a bunch of rest requests.

[lost matrix]

Show more code pls

[echo basalt]

itemtype rework maybe?

[lost matrix]

Wait, is that merged?

?stash

[undone axle]

https://hub.spigotmc.org/stash/

[echo basalt]

no but ppl keep coming up with development builds

[echo basalt]

Ah I see

Generics

Remove the generic on your CommandKit class

[lost matrix]

🤨

[gentle nexus]

oh

my ide added it there idk how

no errors now thx

[twin venture]

i already have JDA installed in my project

[lost matrix]

Well then use it 🙂

When the player types /link then you can just send him a code he has to enter on discord.
In the backend you store <TheKey : MinecraftUUID>.
Then you wait for the player to use a command on discord with the same key.

There are more sophisticated ways, but this is a trivial approach.

[echo basalt]

muh time limit

[lost matrix]

You could also send the player a link with metadata attached. This way he only has to click on the discord link and is attached automatically

[echo basalt]

send a button

or sumn

on discord

tell him to press it at the same time

[lost matrix]

Within 500ms or he is not human

[echo basalt]

same tick

[twin venture]

i already did that , i am asking about how i can get the player rank from minecraft server , and then send it to the discord bot? so he will assign it to the discord user

who linked

[lost matrix]

So you are asking how to send data from one application to another?

[twin venture]

possible?

for example i use luckperms , get the rank player have and assign it in discord

[lost matrix]

Yes, ofc. That how the entire internet works...

[twin venture]

after he do /link

[lost matrix]

There is a million different ways you can do that.
Just use whatever you are familiar with. RPCs are an option. I think discord has those.

[twin venture]

alright thanks , gonna see how i can do it

[lost matrix]

Webhooks work.
Opening a rest endpoint on your bot works. (It uses those anyways).
Sockets work.
Redis or RabbitMQ works.
RPCs (as mentioned before)
SQL update hooks are also ok

[lost matrix]

https://discord.com/developers/docs/intro
Here are all endpoints you can use on your bot

[twin venture]

i decided not to make the fake armorstand with protocollib , i will use a lib for that ..

to much work to support 1.8 - 1.13.2 , 1.16.5 , 1.19.4 , 1.20.4

[river oracle]

Lol bro what is that version support xD

You need mental help?

[tardy delta]

no 1.19.2?

[slender elbow]

why would you lol

[quiet ice]

1.13.2 is a rather interesting one. And why no 1.12.2?

so yes, mental help may be needed

[smoky anchor]

I believe 1.12 is within the range 1.8 - 1.13

[slender elbow]

1.8 ≤ 1.12 ≤ 1.13

1.2.5 ≤ 1.20.4

[quiet ice]

okay randomly using ranges it unfair

[tired star]

Im experiencing weird issue thats related to BukkitTask. I want to execute a task after a delay. However my code seems to run only when the delay is set to 0.

            logger.info("Now inside BukkitTask Task");
            new TridentHandler(player, trident, logger).runTask(plugin);
            cooldowns.put(player.getUniqueId(), System.currentTimeMillis() + cooldown);
        }, cooldown);```

is there something im missing here? 'plugin' variable is defined before task and pointed to my main class that extends JavaPlugin

[tawdry echo]

You using ticks or seconds?

[smoky anchor]

You should not be using Player in tasks iirc
Always use UUID and get the player when the task is run
For your actual problem, idk sadly

[tawdry echo]

I gues seconds

[kind hatch]

Bukkit stuff uses ticks

[smoky anchor]

good point, you have mismatch of time with the cooldown (adding millis to ticks) and using ticks in the task

[blazing ocean]

why is that

[smoky anchor]

I'll let someone smarter explain that, I am not even sure you are supposed to do that here
But I believe it was something with keeping the Player in memory if player already left

[tired star]

i actually have the cooldown calculations in different function that returns the value in milliseconds

[blazing ocean]

i guess that would be a NPE

[meager hollow]

true

[blazing ocean]

yeah you should use ticks

[tired star]

yea gonna do that :D thanks

[smoky anchor]

well no
But it would not do what you want it to do
I think

[blazing ocean]

havent experienced UB in spigot yet, ill test it

[meager hollow]

but why stores Player 🤔

[blazing ocean]

ok i actually cant test it bc im not on my computer nor have friends :D

[tired star]

ive been a fool. thank you guys for help

do you wanna look at a utility i made 10 minutes ago

[valid burrow]

i can send u a project i used to teach fresh beginners java/spigot

dont ask

it came to my head and i was like oh that's brillinnt!

then i made it

and like

xdd i told you i used it to teach people java and spigot

i let them have their freedom

[icy beacon]

double is done for up to 1E303

long exists too

short and float eh

[valid burrow]

i never continued working on this now that i think about it loo

[valid burrow]

stop acting like its MY code 😭😭

[blazing ocean]

wait guys

i have an even better one

not open source

I've seen those team names before

somewhere

[blazing ocean]

hmmmmm

[valid burrow]

enums are overrated

anyways

[blazing ocean]

listen

i was really shit back then

[valid burrow]

too bad

ive seen so much shity code now

that every time i see that fish

[echo basalt]

you probably still are mcci hasn't been a thing for that long

[valid burrow]

i will think of it

[blazing ocean]

😭

that was actually an mcc recreation

before mcci was a thing

🤓

[echo basalt]

same shit

[blazing ocean]

so were just ignoring the fact that it exists for like 5 years or so

[echo basalt]

yeah that's not long

[blazing ocean]

true i havent been doing plugin dev for long

i just wanted to check the first commit and then realised there was no git repo in there 😭

my plugin.yml can time travel

[tardy delta]

player is obviously null then

[glad prawn]

null check then

[tardy delta]

probably followed some npc tutorial

[gentle nexus]

i mean i figured that part out
why tho

[tardy delta]

because one doesnt exist with that name?

print out all player names or smth

[gentle nexus]

do i need to add my player name or somin ?

[tardy delta]

no just make sure its valid, idk where you got that name from

[gentle nexus]

i need my player name
iv made some baisic code that broadcasts stuff when the player joins the server

public void onPlayerJoin(PlayerJoinEvent event) { event.setJoinMessage("Welcome to this server!"+ event.getPlayer().getName()); }

[glad prawn]

yeah?

[gentle nexus]

ye
so then im getting this error in console

Error occurred while enabling pluginname v${project.version} (Is it up to date?)
java.lang.NullPointerException: Cannot invoke "org.bukkit.entity.Player.sendMessage(String)" because the return value of "org.bukkit.Bukkit.getPlayer(String)" is null

[tardy delta]

show surrounding code

[gentle nexus]

its in this class
public class MyListener implements Listener {the methord}

nd some imports thats it

[valid burrow]

event.getPlayer(str) isnt used in that code

thats doesnt really make sense

[valid burrow]

also this is while enabling

how did you setup your main?

i think you didn’t register the listener properly

[scarlet gate]

I'm trying to boost a player's fortune enchantment on their tool by 1 when breaking certain blocks if possible (eg. Fortune 1 gives the drops of Fortune 2)
I currently have tried cancelling the drops and then using Block#getDrops(ItemStack) to spawn new drops but am realising that this would break compatibility with custom drop plugins
Any ideas?

[valid burrow]

u can edit drops on blockbreak

u dont need to cancel and replace

u can edit existing ones

and by making your listener get called last you can make sure that other plugins apply their custom drops first

(event priority)

[scarlet gate]

That solution is definitely possible but I'm not sure how I would calculate the enchantment increases for this

[valid burrow]

get the drops and do x2

or what ever your multiplier is

[scarlet gate]

So manually calculating the fortune for any extra drops is the best way?

[gentle nexus]

public void onEnable(){getServer().getPluginManager().registerEvents(new MyListener(), this);}

[valid burrow]

probably yh

i wouldnt know any other way

[near crypt]

how can i check if the player has no inventory opened

[valid burrow]

csnt

cant

at least for their own inventory

you can only check chests and stuff like that

[near crypt]

i want to check a custom inv

[valid burrow]

p.getInventory

is null

[near crypt]

oh get inventory, ok

[valid burrow]

wait no

one sec

[near crypt]

its never null tho

[valid burrow]

that would get the contents of their imv

yh wait

1 sec

im slow

getOpenInventory @near crypt

[near crypt]

its also never null

[valid burrow]

uhh

i mean

u can cache when ever they open and close their inv ig

[near crypt]

thats what i want to do, but how can i check when the inventory is closed.. this is my problem

[valid burrow]

InventoryCloseEvent

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/event/inventory/InventoryCloseEvent.html

[near crypt]

hmm ok

the thing i want to do is just to stop a runnable when the inventory is closed by the player

[gentle nexus]

wait ima reask my question
It was completely wrong
so my code is
` public void onPlayerJoin(PlayerJoinEvent event) {
event.setJoinMessage("Welcome to this server!"+ event.getPlayer().getName());
Bukkit.broadcastMessage("Welcome to the server!");

}` 

and in my main class
public void onEnable() { getServer().getPluginManager().registerEvents(new MyListener(), this);}

im my chat nothin shows

same as the console

[dry hazel]

you need an EventHandler annotation on the listener method

@EventHandler

[gentle nexus]

oh

so for every event methord i need that annotation ?

[dry hazel]

yes

[scarlet gate]

At what point should I be modifying the drops - I was looking at BlockDropItemEvent and saw that I shouldn't be adding drops through it
"It is not legal however to add new items to the list"

[gentle nexus]

ok it works now
but it says the welcome to the server
and then the welcome to the server ! playername

even tho my code is in the other way

im just wondering whats the reason behind that

[hazy parrot]

I would assume event is called before player actually join

And join message is sent later

While your broadcast fires instantly

[inner mulch]

why cant they just let me do it 😔
java.lang.IllegalStateException: Asynchronous player kick!

[lost matrix]

BlockDropItemEvent is the correct method to modify the drops of blocks.

[lost matrix]

Because that would mess up the entire game state...
Just run the kick method sync

[young knoll]

Why do you need to run a kick method async anyway

[inner mulch]

the player isnt sync after the kick either way, so?

[chrome beacon]

It still needs to be done sync

what happens after it's done has nothing to do with the problem?

[lost matrix]

He is registered in lists, he has an attached entity in the world that needs to be removed sync, the PlayerQuitEvent needs to be called sync.
There are just so many parts that could cause the current tick to throw an exception if you where to force an async kick.

[inner mulch]

ok

[icy beacon]

one can say that

calling it async will violate ocp

iykiyk

[inner mulch]

how do i establish a ManyToOne relationship in hibernate, with just the uuid (primary key for the OneToMany object)

[rough drift]

please separate many to one I did not understand 😭

[scarlet gate]

How would I modify them with that event though?
Also, does Block#breakNaturally trigger the BlockDropItemEvent?

[rough drift]

that was everything I'll say

[lost matrix]

You... put them in a collection and annotate it with ManyToOne?
Idk if i understand the question

[solemn meteor]

how does player.getInventory.getItem(int i) work, like what number do I have to put to get the item of a specific spot

is it 0-35 or 1-36, and does it start the count on hotbar or the top

[inner mulch]

all the tutorials show it with a object reference in the many object

i only have the uuid

[lost matrix]

You need to check the hard coded slots online.
But if you want to get armor or the main/offhand, then there are better ways.

[lost matrix]

!?

[solemn meteor]

where can I get the hard coded slots list? Also yes, theres better ways for armor or offhand but thats not what I need lol

[lost matrix]

Somewhere online 🙂

[echo basalt]

0-8 is hotbar

and then it does 9-35 top left -> bottom right

36 is boots iirc

40 is offhand

[urban kernel]

for required args should i use [] or <>

in my usage

[solemn meteor]

thank you

[lost matrix]

Relationships can exclusively be define between two entity classes.
UUID is not an Entity class so you cant define a relationship with it.

[inner mulch]

i could do it before hibernate 😔

the UUID is referenced in both entities

[lost matrix]

I mean you can just create a table for your UUIDs. And let them be stored for your objects without a relation contract:

    @ElementCollection
    @CollectionTable(name = "entity_uuids", joinColumns = @JoinColumn(name = "entity_id"))
    @Column(name = "playerIds")
    private List<UUID> playerIds = new ArrayList<>();

[inner mulch]

i have 10 items. i have a cart. all the items have a uuid pointing to the carts uuid. why cant i just use the uuid and why do i need the carts object reference when i can just have the uuid?

[blazing ocean]

<>

[solemn meteor]

btw i kinda forgot this part, if you get a slot's item and its empty, does it return null or an itemstack of air?

[urban kernel]

ty

[lost matrix]

Because you are now trying to manually handle relations between objects through implicit references.
This is simply not how relational data works.

[lost matrix]

Also the Items should not know in which cart they are in

[solemn meteor]

if (offHandItem.getType() == Material.AIR) ?

[inner mulch]

in my case the items should as they are bans of a player

[lost matrix]

And what are they relating to?

[inner mulch]

to the bandata so i have all of them in a set

i dont know if there is a getall method in hibernate

i dont know how to get alle references of a uuid

so i just tried it like that

[thick oracle]

Hey,
I'm spawning some Mobs with my plugin, but when I spawn a Mob with EntityType.ZOMBIE it catches on fire.
I know so far this sounds like the normal behaviour, however I have disabled visual fire, so I'm unsure of what to do

Mob mob = (Mob) player.getWorld().spawnEntity(player.getLocation(), EntityType.ZOMBIE);
mob.setInvulnerable(true);
mob.setVisualFire(false);
mob.setSilent(true);

[chrome beacon]

I assume visual fire doesn't override the regular fire

Just give it fire res or smth

[valid burrow]

set fire ticks to 0

[chrome beacon]

Won't help

[valid burrow]

it should if you do it after visual fire is turned of

[chrome beacon]

When spawning an entity and modifying it do use the spawn method that takes a consumer

It makes sure the changes to the mob are applied before it's spawned

instead of after

Could change the result assuming what DrVosss said is true

[lost matrix]

You should maybe draw an ERD.

1. Identify/Create a list of all entities
2. Define all attributes for the entities
3. Map the relationships
4. Minimize common relationships

Then just implement it in code.

[thick oracle]

All the other methods apply apart from the fire (unless I'm misunderstanding the method)
I'd honestly assume that the consumer just passes the created mob, I wouldn't see any reason for it not to

Edit: yea the method seems to just toggle whether visual fire should be always visible, so I'm using the method wrong

[tardy delta]

not even an erd, or a very shitty one

[inner mulch]

thanks, but i dont think my hibernate skill issue is resolved as i dont know how to even set up such relations properly

[dawn flower]

can u custom color a potion while still having a specific effect

[inner mulch]

i havent gotten one to work

[chrome beacon]

Still do use the consumer

[blazing ocean]

might be possible with shaders or resource packs

[dawn flower]

nvm i found setColor in potionmeta

[lost matrix]

Yes

[dawn flower]

^

[thick oracle]

Sadly doesn't work
neither does applying fire resistance

[chrome beacon]

?

Fire resistance should stop zombies from burning

Show your code

[thick oracle]

fire resistance only makes them not take damage tho, no?

[chrome beacon]

should also stop them from starting to burn

if they aren't burning

or so I remember it at least

can check

[thick oracle]

Same code as before essentially. I tried fireResistance before using the method that takes a Consumer<Entity>

Mob mob = (Mob) player.getWorld().spawnEntity(player.getLocation(), EntityType.ZOMBIE);
mob.setInvulnerable(true);
mob.setSilent(true);

PotionEffect fireResistance = new PotionEffect(
        PotionEffectType.FIRE_RESISTANCE,
        Integer.MAX_VALUE,
        1,
        true,
        false
);
mob.addPotionEffect(fireResistance);

[chrome beacon]

interesting it doesn't stop them from starting to burn

Does your code require it to be a zombie

[thick oracle]

I need to work with all hostile mobs pretty much

[chrome beacon]

oh well ig you could use nms

[wary harness]

So I got a problem with one of my plugins is getting flagged as trojan

[wary harness]

there is many people comming asking me why is your plugin tagged as virus

[lean pumice]

generally if you use straight Java with no reflection/tricks you will not be flagged

[undone axle]

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

[lilac dagger]

do you mean concurrent modificationexception?

[lean pumice]

i get error in Team team = arena...

[lean pumice]

yes

[lilac dagger]

you can't remove elements from a collection without traveling

[quaint mantle]

it.type == material.Copper_Blcok doesn't work

[lilac dagger]

however there is the iterator form that allows you that

[lean pumice]

public Team getTeam(Player player) {
return teams.stream()
.filter(team -> team.getPlayers().contains(player))
.findFirst()
.orElse(null);
}

is a simple steam

idk why get error

i mean get error team.getPlayers()

but idk how resolve

[minor junco]

what's the error?

[lilac dagger]

it might be your team.getPlayers, what do you do inside?

[lean pumice]

is a @Getter

is a list

[eternal oxide]

?paste a stacktrace

[undone axle]

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

[minor junco]

btw consider using a Map for O(1), doesn't make much difference for O(n) where n < 100 but still

nobody?

[lean pumice]

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

i really think the bug is elsewhere

[undone axle]

"Does not working" is a useless statement. Please describe what exactly is not working, what you expect it to do, and what actually happens. If you get any console errors, also ?paste the entire stacktrace.

[eternal oxide]

yeah CME

[lost matrix]

For ~100 its already a factor of 10x
So maybe more like less than a dozen

[minor junco]

what kind of list is your .getPlayers() returning

[quaint mantle]

yes but it is obviously wrong and this is a common function

[lean pumice]

Players

[minor junco]

yeah but like noticable

[minor junco]

what list instance

implementation

[chrome beacon]

oh well if it's obvious then you can fix it

[minor junco]

WeakList?

[quaint mantle]

Moron.

[lean pumice]

ArrayList

[minor junco]

well u have to mutate it somewhere while iterating

maybe asynchronously

[lean pumice]

i have try async and not but give always problem

[thick oracle]

that, or the built in EntityCombustEvent 🤦 Man I forgot that exists

[chrome beacon]

ngl I forgot that existed too

[lean pumice]

it give problem when i remove it on death

(the victim)

[lost matrix]

Quite a few things.
I would write it like this:

playerInventory.first { it != null && it.type == Material.COPPER_BLOCK }

In which case you might as well use spigots method for this

[minor junco]

nah I mean you may mutate it at some point asynchronously

not iterate over it asynchronously, tho that also can give issues

[lost matrix]

Here is the method spigot already provides:
https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/inventory/Inventory.html#first(org.bukkit.Material)

[lean pumice]

nope, i have try now

[chrome beacon]

Are you making a plugin?

[eternal oxide]

check for startup errors

[urban spire]

no, i miss the channel. I am just trying to connect plugins to mysql

[scarlet gate]

Does Block#breakNaturally call BlockDropItemEvent

[chrome beacon]

I believe so

[lost matrix]

Probably not

[scarlet gate]

Ahh ok, I was just trying to use it but couldn't work out why it wasn't calling

I had assumed I made a mistake with my listener, what would be the best way to replicate a player breaking a block?

[chrome beacon]

right it requires a player

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/entity/Player.html#breakBlock(org.bukkit.block.Block)

try this

Additionally, a BlockDropItemEvent is called for the items dropped by this method (if successful).

in javadoc note

[scarlet gate]

Ooh very handy

[acoustic pendant]

is there any way to make so entities (armor stands for example) does not interact when placing blocks or hitting?

[chrome beacon]

armor stands have the marker flag

[acoustic pendant]

oooh, true

thanks

[onyx fjord]

how do sound categories work, do they change anything related to the sound name when trying to play it?

[kind hatch]

Sound categories are tied to the user sound settings.
They are basically sound channels.

[onyx fjord]

i see

[kind hatch]

Select the channel you want to play the sound on and then it’ll go through the user filters for volume.

[scarlet gate]

Is there a way to do #getDrops on a block state / material?

[chrome beacon]

Not recommended

use the BlockDropItemEvent

[scarlet gate]

I'm unsure how that would help?

[chrome beacon]

It depends on what you're trying to do

[urban kernel]

i use Java 22, selected in my project settings.

When I compile I get this error.

Unsupported class file major version 64

(I use Maven)

How do I fix this error?

[chrome beacon]

Use Java 17

[urban kernel]

I did before, but I got an error with classfile major 65

[scarlet gate]

I am trying to give the player the equivalent of +1 fortune drops. So if they have Fortune 3 on their pickaxe then they'll receive some extra drops for the difference between Fortune 3 and 4

[chrome beacon]

65 is Java 21

Something you're depending on requires it

[urban kernel]

I'm using 22, which should backport 65?

[dapper flower]

is there an event that gets called when an anvil operation happens?

[chrome beacon]

Are you sure you're using 22

uuuh, do you maybe know how to for older versions? I'm looking to support 1.8+ (in that page there is another method, but supports 1.16+)

[tender shard]

in 1.17 and older you'll need to use reflections.

this method gives you an itemstack for a base64 skin: https://github.com/mfnalex/JeffLib/blob/master/core/src/main/java/com/jeff_media/jefflib/SkullUtils.java#L138
and this method does the same for a placed head: https://github.com/mfnalex/JeffLib/blob/master/core/src/main/java/com/jeff_media/jefflib/SkullUtils.java#L97

k ty

oh lol

[lost matrix]

Man the new snapshot is wild...
Any Item can be anything now. You can make gunpowder consumable and red dye a tool for breaking wood.
And anything can have durability now. And we finally have custom durability values and stack sizes (up to 99 i think).

[eternal oxide]

nice

[lost matrix]

But one thing that caught my eye was this: Completely data driven item predicates

This would allow for recipe choices like *[damage~{durability:{min:3}}]
=> any item which has at least 3 uses left
and even for custom data predicates (since that also just a component now).

If we where to add an API layer for it

[quaint mantle]

MMORPG servers gonna glow up with this one 🗣️

[tall dragon]

the best thing is. that u can now make anything eatable :d

[lilac dagger]

how does that work?

or is it a flag?

[lost matrix]

Customizing items will be actually wild now.
Just a random idea: Creaft a ton of bonemeal together, get a Bonemeal ItemStack thats not stackable and has a durability of 100 or so,
on use it loses durability and you actually see the green bar on the item going down

[tall dragon]

components

[tall dragon]

yea there are so many nice opportunies with this

[lost matrix]

Or a "Deep water bucket" where you can actually store dozens of source water blocks

With a bar filling up

[tall dragon]

& custom food will be alot easier as well

[lost matrix]

This enables so much...

[lost matrix]

Yes...

Custom expensive combat food that can be instantly eaten

[tall dragon]

yea this choice is actually really nice by minecraft

[lost matrix]

I love all of this data driven stuff. We gonna have a blast with it.

[sand spire]

does that mean i can finally have an item of choice with bundle preview

[inner mulch]

is this gonna be in 1.21?

[orchid trout]

dont people still use versions like 1.17

i feel like this is gonna take like 5 years for people to start using

i will use it :)

[tender shard]

yeah i like that

[sand spire]

where is 1.8.9 i thought that was the version most 1.8 pvpers played

[tender shard]

IIRC latest server version is 1.8.8

[wet breach]

that is a client update

not a server update

one of the few instances where the client version didn't match the server version or didn't need to anyways

[young knoll]

1.20.5

[silent slate]

Hey, i am coding a plugin rn that lets players switch between inventories per world. Now i get errors that an item does exist.

My codes does this:

1. Take inventory and encode to base64
2. save that string using yaml.
3. Get the string and decode it and set it into the players inventory

My yaml looks something like this:

uuid + "." + world + "." + "buildinventory" has the string of the "buildinventory" stored in it

uuid + "." + world + "." + "normalinventory" has the string of the "normalinventory" stored in it

and 

uuid + "." + world + "." + "buildmode" has a boolean wheater or not the player is in the buildmode, true meaning he is in the buildmode, false meaning he is in normal mode

This is my code:
https://pastebin.com/1sfCPx6S

If you need more details im open to vc or tell u more, its very "complicated"

[tender shard]

stacktrace?

[lost matrix]

1.20.5 i believe

custom stuff is gonna be so easy now

[tender shard]

send the stacktrace pls

[silent slate]

ok gute nacht

im working on it tomorrow

[lilac dagger]

10% on legacy stuff nice

[orchid trout]

1.8 pvp is superior

[lilac dagger]

not really

you just jitter spam and that's it

what a mouse killer strategy

[orchid trout]

knockback items

w tapping

bow boosting

it just doesnt feel the same

youre forced to play slow

[sand spire]

I prefer 1.9+ pvp with a sword but items like shields, end crystals and now the mace kinda ruin it for me

good thing as a programmer I can bend pvp to how I like it 👍

[orchid trout]

even without shields you just end up trading hits

[sand spire]

trust me combos exist in 1.9 pvp

Hello everyone!
I've a problem on my proxy/spigot server and chat validation message.

lost connection: Chat message validation failure

Do you know how to desactivate it?

[silent slate]

Are you using nms/packets?

[sullen wharf]

Is there any way to forcibly render an entity when it is high up?

[rough ibex]

Pretty sure thats client side

The client decides what to render

[tall dragon]

well there is this https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/LivingEntity.html#setRemoveWhenFarAway(boolean)

[rough ibex]

That despawns

But I don't think you can force the client to render anything

[young knoll]

Only an option for display entities

[torn shuttle]

whoever said chatgpt will outright replace programmers is smoking some fine crack

had a long day today that consisted of looking at chatgpt output and shaking my head

[vocal cloud]

It's also making people dumber
Exhibit A: https://hackerone.com/reports/2199174

[young knoll]

Ah man can’t wait to make up vulnerabilities to claim bug bounties

[quiet ice]

the curl guy posted a rant about that

[rough ibex]

I remember reading that

[ember dew]

I'm losing braincells doing this, I've spent an unreasonable amount of time troubleshooting and give up.

I'm trying to add this a user into a hashmap and it simply won't output the the user I've just added to the hashmap and instead returns it null

HashMap<String, Boolean> map = new HashMap<>();

            Player p = (Player) commandSender;
            map.put(p.getName(), false);
            System.out.println(map.get(p.getName()));

[eternal oxide]

nothing wrong with that tiny section of code you posted.

[ember dew]

Give me a moment

I'll just post the entire thing

    @Override
    public boolean onCommand(CommandSender commandSender, Command command, String s, String[] strings) {

        if (commandSender instanceof Player) {
            Player p = (Player) commandSender;
            Boolean active = false;
            try {
                active = QillaPlugin.godMode.get(p.getName());
            } catch (NullPointerException exception) {
                QillaPlugin.godMode.put(p.getName(), false);
            }
            if (!active) {
                QillaPlugin.godMode.put(p.getName(), true);
                p.sendMessage(ChatColor.GREEN + "You have been made invincible.");
            } else {
                QillaPlugin.godMode.put(p.getName(), false);
                p.sendMessage(ChatColor.RED + "You are no longer invincible.");
            }
        } else if (commandSender instanceof ConsoleCommandSender) {
            System.out.println(currentCommand + " cannot be run by console.");
        } else {
            System.out.println("There was an error running " + currentCommand);
        }
        return true;
    }

This is in a different directory

    @EventHandler
    public void OnDamage(EntityDamageEvent e) {
        Entity entity = e.getEntity();
        if(entity instanceof Player && QillaPlugin.godMode.get(entity.getName())) {
            e.setCancelled(true);
        }
    }

And this is the hashmap setup in the main directory

public static HashMap<String, Boolean> godMode = new HashMap<>();

It gives me null at the first if statement "if (!active) {"

[ember dew]

This works just fine

[eternal oxide]

active is a Boolean so can be null

it will never throw an NPE at the get

[echo basalt]

Isn't a set a better data structure for this?

And shouldn't we use player ids instead of their username?

[ember dew]

Yeah

This is just a proof of concept for myself

I just got into java a week ago

[eternal oxide]

use boolean not Boolean

[echo basalt]

Still good to learn good habits from the beginning

[ember dew]

If you're talking about the hasmap, it can't be primitive

[eternal oxide]

no

the active variable

[ember dew]

Jesus christ

[ember dew]

That's it

Appreciate it, I would've overlooked that a million times

[ember dew]

Why's that?

[eternal oxide]

a Set can't have duplicates.
You only add a players UUID to the Set if they are in god mode.

[young knoll]

Mapping something to a Boolean -> just checking if a set contains that something

[eternal oxide]

if (godMode.contains(p.getUniqueId()))...

[ember dew]

Yeah that totally makes sense

[eternal oxide]

names can change, The Player object can change. UUID is unique.

[ember dew]

I'm fully aware, I was just too lazy to find a way to pull a uuid from the Player object rn

[agile anvil]

HashSet internal uses a HashMap iirc

[agile anvil]

As the #getName there is a #getUUID

[eternal oxide]

it does, and just uses the KeySet

[ember dew]

Oh cool

[agile anvil]

Ah yeah true true

[agile anvil]

So Set is still better ahah sorry

[young knoll]

When you plug the guava concurrent map with weak keys into Collections.newSetFromMap

Massive brain

[ember dew]

I'll assume it's getUniqueId

Idk how I overlooked that

[eternal oxide]

easy to do as everyoen talks about UUID not UniqueId

[ember dew]

Would it be better to put lists inside of the main file, inside the listener for godmode or a completely separate file

[eternal oxide]

depends where you need to access it

[ember dew]

But in this case, for performance

[eternal oxide]

if multiple listeners need it then it has to be at a higher level in yrou design

performance makes no difference

[ember dew]

Alright

Should I be converting the uuid to a string before putting it into the set?

[eternal oxide]

no need

its a comparable object

Set<UUID>

[ember dew]

Oh, I tried to put a uuid into a string and it gave me an error

[eternal oxide]

you could rotate around Y

[young knoll]

It’s also probably in radians

[eternal oxide]

ah yeah it's not goign to account for a non 45

just calculate teh pitch +90

does CB cap pitch at 0?

in location

CraftBukkit

here http://www.java2s.com/example/java/java.lang/generates-a-vector-that-forms-an-angle-of-90-degrees-with-the-given-ve.html

thats 2d, but not hard to 3d it

[echo basalt]

isn't that the cross product?

[agile anvil]

Rotate of 90 degrees in a 3D space doesn't mean anything. What you want is the orthogonal (in 2D orthogonal = perpendicular) of a plan

So you need two vector defining your plan. You already have one (the direction)

[eternal oxide]

you need the blue line

[echo basalt]

Problem is that you're dealing in 3 axis

[eternal oxide]

from the existing white one

nah not hard.

take a look at this. it will draw a half circle based upon the players eyeLocation

apply it to your stand, and you'll be able to work out what step you need

    public static void halfVertical(Player player) {

        double radius = 3;
        double every = Math.PI / 30;
        Location loc = player.getEyeLocation();

        for (double rad = 0; rad <= Math.PI; rad += every) {
            double x = radius * Math.cos(rad);
            double y = radius * Math.sin(rad);

            double rotateZ = Math.toRadians(loc.getPitch() + 90);
            double rotateY = Math.toRadians(-loc.getYaw() + 90);

            Vector rotate = new Vector(x, y, 0);
            rotate.rotateAroundZ(rotateZ);
            rotate.rotateAroundY(rotateY);

            Location finalLoc = loc.clone().add(rotate);
            player.spawnParticle(Particle.FLAME, finalLoc, 1, 0, 0, 0, 0);
        }
    }```

you just need to find the rad to plugin in

[agile anvil]

So there is actually an easier method

To define the "plan of your direction" you can just use two vectors:

• The direction vector that you have
• An arbitrary vector like (1, 0, 0)

Once you have those two vectors you can do the cross product between those two

You should get the resultant orthogonal vector

(don't forget to normalise)

Vector direction = yourDirection;
Vector plan = new Vector(1, 0, 0);

if (Math.abs(direction.dot(plan)) > 0.999) {
    plan = new Vector(0, 0, 1);
}

Vector orthogonal = direction.getCrossProduct(plan).normalize();

There is maybe a shorter way but I'm on my phone

You have to use Vector#getCrossProduct

Because Vector#crossProduct changes the original vector

[young knoll]

Is that even a thing

[agile anvil]

Yes, vec = orthogonalVector in that case

[young knoll]

Pretty sure all the methods mutate

So you should clone

[agile anvil]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/util/Vector.html#getCrossProduct(org.bukkit.util.Vector)

[eternal oxide]

getCrossProduct returns a new vector. where crossProduct mutates

[agile anvil]

Don't forget to check the dot product between your arbitraryVector and the direction vector. If those two vectors are colinear it will not work

[minor garnet]

https://hub.spigotmc.org/stash/projects/SPIGOT/repos/bukkit/browse/src/main/java/org/bukkit/util/Vector.java

[young knoll]

Huh

Like the only method that has a non mutating version

Man vectors are my biggest annoyance atm

There’s so many different ones to convert between

You’ve got vector, then joml’s vector, minecrafts vec3, minecrafts blockpos

[agile anvil]

Yeah this is a pain

[young knoll]

And they are basically all the same, but not directly interchangeable

😩

[agile anvil]

Yeayy

That's why I love maths

I said I love maths, not physics 🥲

[young knoll]

Just steal sethblings datapack :p

And javaify it

This is why display entities are better

Boo

I refuse to acknowledge anything before 1.19.4 anymore

[agile anvil]

You have to account the head base to do some projections I'm afraid

And this

is a real pain

bro wants to get unreal engine cars into mc

This is a really interesting project indeed. But I'm very scared of high ping players lmao

[rough ibex]

vectorile dysfunction

[young knoll]

I feel like I should ban you just for that

[obsidian plinth]

Do it

[agile anvil]

Does it get you a vector pointing down?

[rough ibex]

hah

wish I knew the answer

[obsidian plinth]

If (vector == dysfunctional) {
Make not dysfunctional
}

[agile anvil]

what the

[minor garnet]

boy

[agile anvil]

(0, 1, 0) coul'nt work end that's normal

But the others are acting weird

Let met think about it

[astral scroll]

can i get help? My BlockBreakEvent isnt being executed

it has @EventHandler

and the listener is registered

and SpawnManager is being used

[remote swallow]

double check the init function is called

[astral scroll]

im checking that

im opting for smth better

[rough ibex]

better? such as?

[astral scroll]

i was doing something really wrong

i was storing the whole SpawnManager lol

so id just

created a data class

with the data i needed

world, region and spawnpoint

and stored it apart

from the spawn manager

so i assure init is being called

and yet still not working the way i want lol

but yeah

i think that it is my adapters

lol

there it is

[rough ibex]

Is there a reason you escape < >

[astral scroll]

wdym?

[rough ibex]

you write \u003c

[astral scroll]

idk

is gson

lol

[wintry lynx]

Anyone know how i'd get the "charged-projectiles" from this item. This item being written as item.
I tried metadata but I got no clue how to grab it from there.

[remote swallow]

cast meta to crossbot meta
