[eternal oxide]

use the spawn method which takes a Consumer

[hushed spindle]

you dont need to use nms to break blocks in an area yeah but for the breaking animation you do

[eternal oxide]

in the consumer you sety invisible and it's never seen

[eternal oxide]

nope you just send fake block damage

[dry forum]

ok thanks

[hushed spindle]

yeah so you either use nms or like protocollib

[smoky oak]

theres a particle now

[eternal oxide]

fake block damage is API

[hushed spindle]

oh is there

ah i see

seems some support was added in 1.19 and a bit more specific implementations in 1.20

if you want your plugin to be compatible with older versions than that you'll still need to do stuff with packets though i reckon

[smoky oak]

well im certainly not gonna end up in a

?1.8.8

situation

[eternal oxide]

lol

[smoky oak]

welp i tried spamming it but forgot it is 1.8

not 1.8.8

[cyan void]

anyone know how i can make a custom mob system were mobs spawn in a rigon with custom names and all that

[hushed spindle]

i mean anytime you spawn an entity you get it returned and so you can edit it with equipment or custom names or whatever

so thats not an issue

spawning them within a region means you gotta hook into worldguard and go through a region to get its valid spawning spaces

spawning mechanics themselves you gotta figure out in what way you wanna do that

or the easy method would be to listen to mob spawn events and edit those mobs if they spawned within that region, if you dont mind using vanilla spawn mechanics

depends on what you want to do

@cyan void

[slow light]

guys

Non-static method 'getInventory()' cannot be referenced from a static context

So

im trying to make

a command

that gives players

a item like /give

when the command is run

but the problem is

that

getInventory() isnt static

i mean

im kinda confused

[chrome beacon]

You need an instance

of whatever you're getting the inventory from

[slow light]

so a instance of bukkit api?

[chrome beacon]

An instance of the object you're getting the inventory from

Could be a chest, furnace anything really

[slow light]

so i have to instance

getInventory?

[chrome beacon]

??

[slow light]

im trying to use getInventory

to add a item

to a players inventory

so i have to instance

getInventory

right

[chrome beacon]

no

If you want the players inventory

you need the players instance

to get the inventory from

[slow light]

k

[chrome beacon]

How else would it know what player you're referencing?

[slow light]

hm k

[chrome beacon]

Might be a good idea

[slow light]

i am

learning java

i started 2 weeks ago

have some chill

[chrome beacon]

You're supposed to do that before starting with Spigot

[cyan void]

event.getPlayer().getInventory()....

[ivory sleet]

🥲

[cyan void]

i thnk

[ivory sleet]

yeah thats valid

[hushed spindle]

also

please

stop talking

like this

[quaint mantle]

does anyone know how i can make my plugin work with old versions?

[chrome beacon]

Write code for the oldest version you want to support

If you want 1.8-1.20 write the plugin code for 1.8

[quaint mantle]

so if i write it for 1.8?
it'll work till 1.20?

[chrome beacon]

and then if you want to specifically support newer features you'll need a version check and only run code supported

[quaint mantle]

is there a wiki for this or like a page that can help with examples?

[chrome beacon]

Example for what part?

[quaint mantle]

like these two only
Location location = player.getLocation();
player.playSound(location, sound.ENTITY_ENDER_DRAGON_DEATH, 1f, 1f);
Player player = e.getPlayer();
player.sendMessage("Welcome to RomanMc!");

[atomic niche]

Here's an example of a relatively easy way to only use new features if they are available.
https://raw.githubusercontent.com/stargate-rewritten/Stargate-Bukkit/nightly/src/main/java/org/sgrewritten/stargate/property/NonLegacyMethod.java

[warm light]

what is the slot number of head?

in player inv

[eternal oxide]

just use teh helper methods

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/inventory/PlayerInventory.html#getHelmet()

and set of course

[atomic niche]

then just do something like

        if (!NonLegacyMethod.NAME.isImplemented()) {
            //Fallback
            return;
        }
        //use of the new method

[warm light]

I need the slot number

[eternal oxide]

for?

[warm light]

I want to check if player clicked on helmet slot

[eternal oxide]

https://www.spigotmc.org/wiki/raw-slot-ids/

note they are raw slots

[warm light]

[next stratus]

I was updating one of my friends old projects what uses nms and I forgot.... nms is all obfuscated ;-;

[shadow night]

Lol

Old times

[next stratus]

I'm not too bothered about doing it though, he's helped me a lot by making this project so it's the least I could offer

[hushed spindle]

is there any item persistence method that saves all details of an item but not including some version

i would like spigot to not care if an item made in higher versions is deserialized on older versions

[shadow night]

I was recently deving for (craft)bukkit b1.7.3 and it's so shitty, for custom inventories you need nms because there was no api at all for invs it seems lol

[next stratus]

1.7.3 ?

[shadow night]

Whats wrong

[next stratus]

No no, I'm just asking if you meant 1.7.3 or if I was reading wrong

[shadow night]

The beta 1.7.3, yes

[next stratus]

Ah wow, long time since I heard those numbers!

[shadow night]

Very nice version, very not nice bukkit and even worse mcp

[raw epoch]

1.7.3 is july 8, 2011.

[next stratus]

Is it sad I can remember the exact patch version I started mc on?

[raw epoch]

:kappa:

[shadow night]

No, that's cool

[next stratus]

1.6.4 🥲

[shadow night]

Time flies fast

[next stratus]

yeah man

Actually idk if it was 1.6.4 now

[shadow night]

Well, oof

[next stratus]

https://tenor.com/view/reading-gif-8290134

lemme just check the version history

I remember the date exactly so would be easy

1.7.4 oof

I was on xbox for a lot longer though

[wet breach]

yes

[shadow night]

Lol, I started playing on a friends playstation. Bought minecraft java right before 1.12.2 released

[next stratus]

I was defo before 1.12

I am starting to look at retiring my mc account soon, gonna suck to do it but gotta grow up :/

[shadow night]

Whaa

[rotund ravine]

Haven't actually played for ages 👀

[eternal oxide]

lol I'm way into my 50's and I've never grown up

[rotund ravine]

anyone know any good and populated modded minecraft servers?

[next stratus]

Is there a list of v1_19_R1 numbers anywhere so I don't go wasting my time making code what won't be used?

[eternal oxide]

numbers?

as in servers running it?

[next stratus]

Thank you very much

[atomic niche]

Does anyone else have an irrational hatred of nms?
Sure, it's powerful, but it's a pain to maintain, makes more work for oneself, and means that every time someone else wants to do the same sort of thing, they basically need to duplicate your implementation or reimplement it themselves.
Every time that nms is needed, it's easier in the long term just to pr it into or downstream of spigot.

[eternal oxide]

NMS should be a last resort.

[atomic niche]

Making a pr every time we need nms is a pain, but it's saved us a lot of long term maintenance work

[pseudo hazel]

im glad to have never needed nms

[minor junco]

just make it easy for yourself so you barely have to use nms lmao, makes things future proof

[atomic niche]

We are currently nns free. But it's taken a lot of paper and spigot PRS to get to that point

[minor junco]

or through a bridge like protocollib

[eternal oxide]

Thats what PR's are for. Add functionallity to the API

[atomic niche]

The only thing worse than nms is nmc, but I just hate reflection in general.

[eternal oxide]

nmc?

[atomic niche]

net.minecraft.client as opposed to net.minecraft.server

[eternal oxide]

ah

[atomic niche]

They are both a nuisance, but nmc is slightly worse

The one negative of this approach is that our releases for past versions are comparatively limited since it's only logical to pr to the recent version.

But a degraded legacy experience is still better than needing to maintain a load of reflection throughout every version of MC.

Also, there's really no need for legacy esrs to be fully featured

If the people on our ancient esrs want modern features, they should just update to 1.20.x

[knotty aspen]

Opposite, I barely use the API anymore. Its way too dated in a lot of areas

[eternal oxide]

oh god no

[knotty aspen]

Maybe I just have an irrational hatred of enums

[knotty aspen]

Tbf I don't make public plugins, so its mostly own server fork + internal plugins

[hushed spindle]

building the 1.20.3 jar saves it as 1.20.4

is that a bug lol

[dry hazel]

using 1.20.3 is pretty pointless

[hushed spindle]

alright

however

i didnt ask

need it just as dependency just to have that version covered

not using it

[dry hazel]

I'm pretty sure it's done intentionally

[river oracle]

its done intentionally

1.20.3 = 1.20.4 there was one line of code changed

and it was a item deletion bug

any servers on 1.20.3 should be 100% compatable with 1.20.4

vise versa unlses a plugin's NMS interacts with the 1 line of code changed there should be no discrepencies @hushed spindle

[hushed spindle]

ah i see

it refused to work with 1.20.3 anyway so that makes sense

[river oracle]

BuildTools 1.20.3 builds 1.20.4

[hushed spindle]

as spigot-version i mean

[atomic niche]

But therein lies the problem;

The dated sections encourage more people to use NMS instead of making prs for publicly beneficial changes. This leads to those sections becoming even more dated, resulting in more people using NMS.

Even though making changes into public prs is more work, in the long term, it's better for everyone. Without that, everyone is just working on reimplementing things others have already privately done.

[hushed spindle]

is there any way i can tell bukkit to not care if serialized items have a higher version than the server they're deserialized on

[river oracle]

no

[hushed spindle]

darn

do you then happen to know of an itemstack (de)serialization method that covers all metadata and custom nbt

so that it doesnt include a version at all

[rotund ravine]

Realistically that would break a lot

It's backwards compatible, but not forwards compatible

[rotund ravine]

btw i think paper stopped relocating nms in more recent ones

[eternal night]

not yet ™️

[rotund ravine]

ahh alright, just saw it mentioned somewhere and thought you were starting to do it. my bad

[eternal night]

Yea we just warned a bit ago

as that might happen ™️

[river oracle]

This won't break Bukkit#getServerVersion or whatever right

I use that for my NMS and manually map into the release versions

[eternal night]

nah

that is fine

the thing that basically breaks is parsing the thing from like Bukkit.getServer().getClass()

[river oracle]

oh why would you do it like that? seems kinda weird

[eternal night]

String craftBukkitPackage = Bukkit.getServer().getClass().getPackage().getName();
// This is the *bad* part, including any other parsing of the version
String version = craftBukkitPackage.substring(craftBukkitPackage.lastIndexOf('.') + 1);
if (version.equals("v1_20_R1")) {
    // ...
} else {
  // Unsupported
}

like, that would explode

but like, idk why you'd do that

[river oracle]

weirds

[eternal night]

yea, weird nms people

[river oracle]

i have a python script to auto update my NMS :P

maximum lazy

[eternal night]

[river oracle]

still need to script mappings changes though

this is how the real ones do it

[molten hearth]

is it possible to use components or smth with inventory names? because i'd like to change the font of an inventory name

[orchid gazelle]

does this somehow fix those version-dependent imports?

via reflection?

[chrome beacon]

nms is always an option

you just do what you always have done? Each version is a different module

you use the Versions to get which module you should load with reflection

minecraft totally

We would need much more information to atleast try to guess.

Like what are you trying to click out

which spot is it in

[naive loom]

the result item?

[rotund ravine]

Congrats, the result item is what when you are trying to click it out?

[naive loom]

?

[rotund ravine]

I give up

[river oracle]

are you working with an anvil in the physical world

if not expect trouble

you will recieve no help regarding such issues as well. This is already a well known issue and it has a PR to address it if you want virtual Anvil Inventories you'll have to use NMS

[naive loom]

Physical anvils,

[half arrow]

Can anyone suggest the best way to get mob heads for 1.20?

[naive loom]

i'm manually setting the result item because im making a certain item enchantable

there are no restrictions on Physical Anvils or issues

I'm not sure how to explain the issue.

[rotund ravine]

Requote in #general

[river oracle]

/give

its pretty great

[rotund ravine]

Oh i got that guy blocked

[river oracle]

if you wanna use code you can always add items ot the player's Inventory

[half arrow]

Helpful

as always

[river oracle]

if you aren't going to be more specific don't expect a better answer

[naive loom]

It's just the item in the result slot is not able to be moved, the item is being set manually when paper and a enchant book and then it puts the enchantments on the piece of paper and sets it to a cloned item stack in the result slot.

My issue or?

[lost matrix]

Listen to the InventoryClickEvent on priority MONITOR and make sure the event is not cancelled.

[jagged quail]

ok hopefully this works

[naive loom]

I should of thought of that, thank you will look into it real quick. Other than that would anything else that you know of prevent the item from being able to be dragged?

A issue where the result item can't be pulled out of a physical anvil.

[rotund ravine]

I mean.

Is your plugin the only one on the server?

[jagged quail]

if it works it works

[rotund ravine]

What does your plugin do?

[naive loom]

yes

which is why it doesn't make sense

[jagged quail]

yes

[naive loom]

i know my plugin isn't cancelling it

[rotund ravine]

steamworks

I still want to know

what ur plugin does.

?paste

it's a hat plugin

you can equip hats with custom model data

is having a lot of static methods bad? People seem to hate them

[river oracle]

Static is great

[jagged quail]

its only 21 versions out of date

[shadow night]

In util classes, probably not. But otherwise, burn it.

[river oracle]

It's not great when used in properly

[proud badge]

Ok cause I have like 20 static methods in my whole plugin

[rotund ravine]

?static

alexxx

where is it

[quaint mantle]

It ruins encapsulation and it can be called everywere.

[river oracle]

Well there are other use cases too like singletons for example

[lost matrix]

Static is dangerous. They are only fine when completely stateless.
They should not exist in any other context.

[shadow night]

Yeha that's fine

[rotund ravine]

https://blog.jeff-media.com/static-methods-and-fields-when-to-use-them-and-when-to-avoid-them/

[quaint mantle]

Only use it for util classes

[rotund ravine]

@lost matrix I feel like that question warrants a macro

I have felt the need to throw that out a lot

[shadow night]

Maybe static can be used to share a value across instances of the same class or something

[lost matrix]

Hmm

[shadow night]

I wonder when that could be the case though

[eternal night]

never

[quaint mantle]

Singleton

[proud badge]

Most of my static methods are private static

[naive loom]

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

The question is: Are they stateless

By looking at them 🙂
If they modify data outside their scope, then they are not stateless.

[proud badge]

heres an example of one

[rotund ravine]

Modifies itemstack 👀 🎋

[quiet ice]

Hello everyone! It's me - geolykt - and I have another highly specific query: Is a object that is stored in a local variable but isn't actively being referenced anywhere considered strongly reachable? Aside from asking why the hell geolykt would do this sort of thing, would I need to do

void myMethod(Object o) {
  someReference = new WeakReference<>(o);
  someOperation();
  Reference.reachabilityFence(o);
}

or is that plainly superfluous?

[rotund ravine]

geol

What is this

Are you really asking or?

[quiet ice]

Yes, because I have no true idea what classifies as "it can be reached by some thread without traversing any reference objects"

[lost matrix]

Yes. Imagine getting your objects collected while executing a method.
A method scope strongly binds Objects.

[quiet ice]

Without JIT this question is nonsensical, but with JIT one might think there is no real difference between discarding some object and keeping it in the local variables

[lost matrix]

But you can easily test this by starting a thread and keeping the object hostage in a while loop 🙂

[quiet ice]

Nah, I just wanted to check whether I could do a quick and dirty check whether someone was actually calling my method with an autocloseable that was properly wrapped in a try-with-resources. But in that case I'll just drop that idea

[lost matrix]

I would say that this should not be a static method.
If you pass a String to it in addition to the ItemStack, it could be considered a utility method.

[sullen marlin]

A try with resources is just a try finally

You can't detect that

[proud badge]

A lot of my static methods are just methods to obtain which items I should put in a GUI menu

[quiet ice]

Yeah, though I assumed if the reference goes poof that there is great evidence that something was highly wrong with the caller. But as smile says it isn't that easy.

[late sonnet]

[tribal cypress]

Hey, is there anyway to modify the console output for chat logging? I'm currently making a plugin which gives the ability to change a player's name, which utilizes the Player#setDisplayName method, which changes the player's name in the chat, but also in the console.

This makes the server admin (or others with console access) unable to determine who the player is/was at the time. I was hoping to see a way to modify the console output, so that I can put their real name infront of their fake name.

Yes, I know I can do this via printing a message right under the original, but that'd just clutter up console imo

[rotund ravine]

Make you won chatplugin @tribal cypress

[tribal cypress]

That won't change console logging tho.. ?

[rotund ravine]

It will depending on how you do it.

[tribal cypress]

Cancel the message and send it using bukkit broadcast?

I guess I answered myself, but I'm still open to other suggestions, as I don't want to override the messaging just cuz of a nickname plugin, y'know

[rotund ravine]

Other solutions will result in a lot of crap.

[tribal cypress]

Ah, alright, thank you then for you advice

[proud badge]

Ok so how I understand it - if I have the Bukkit.runTaskAsyncronously whilst another async task is already running it will wait until that async task is done and only then run the new one?

[echo basalt]

It will schedule for next tick

iirc

[quiet ice]

yeah, but that next tick could be in a few µs

[proud badge]

What if the async task takes longer than a tick (the original one)

Or are async tasks usually fast

[quiet ice]

Well it depends on your code and how other tasks look like

[echo basalt]

I feel like the async executor should have multiple threads

[quiet ice]

Generally you wouldn't need that precision though - if you do, you should think about your design a bit

[young knoll]

it does

[quiet ice]

Though, hardware limitations still apply

[young knoll]

Eventually

I managed to have like 150 craft worker threads running once

[proud badge]

What would be the best way to check if a block is natural or not without having to make an async task on blockbreakevent to the coreprotect database

[clear elm]

Have I use Java oder Java script for plugins ?

[orchid gazelle]

java

[clear elm]

Thx

[ivory sleet]

Yeah isn’t it just a cached thread pool underneath?

[young knoll]

Yes

With no upper bound apparently :p

[ivory sleet]

Yeah iirc it just uses a default configured thread pool

[opal juniper]

sounds fun

[ivory sleet]

And I mean I think that’s fine, like if you use it for longer surviving tasks then thats on u, kinda goofy

[young knoll]

It wasn’t my fault my loop never ended

Okay maybe it was

[dry forum]

would running location.distance every tick cause lag?

[quiet ice]

but you didn't mean it, right?

[young knoll]

Oops didn’t mean to

[quiet ice]

if you only do it once, not really - it is just some rather basic math

The only semi-serious thing is that it does a squareroot which is why you should prefer distanceSquared when comparing it with a hardcoded value. But even that is not a serious issue

[dry forum]

alright thanks, also im asuming it returns the amount of blocks between 2 locations or?

[young knoll]

Kinda

If the points are lined up on an axis then yes

[quaint mantle]

so uhh having an issue where the config file no matter what i do keeps showing this even if i delete it or make a new one
https://paste.md-5.net/iwikijajez.php

can some help me

[quiet ice]

It just does dist = sqrt(distSq) and distSq = (this.x - x)² + (this.y - y)² + (this.z - z)²

[dry forum]

oh k thanks

[young knoll]

Yay triangles

Well, 3D triangles but yeah

[quaint mantle]

I'm more of circles

They are just awesome

Not on a computer

It's impossible, as the computer draws pixels

The monitor*

You don't see a circle on a monitor, never

Just a set of pixels very close to each other making the shape of a circle

[echo basalt]

just cos, sin

except you're downscaling a vectorized shape to a bitmap

[wet breach]

Depends on the screen being used

Crt's for example can draw circles

[torn shuttle]

god I hate the cold

[quaint mantle]

Do those still being used?

[torn shuttle]

it's miserable to work in

[quaint mantle]

I love the cold

[torn shuttle]

does it hurt?

[wet breach]

Of course

[quaint mantle]

It's better than being all wet with sweat

You take out clotes and you still being hot

Cold is better

You put a little bit more of clotes

And done

[quaint mantle]

Interesting

Where?

[torn shuttle]

I go to the gym even during winter time, I pay to get sweaty

and it's still miserably cold

[wet breach]

Probably better if i list the advantages so you can gauge where they might still be used

[quaint mantle]

Ye

[torn shuttle]

high refresh rate is one, other displays have caught up

[wet breach]

Crts have better color representation especially when it comes to gradients. They are more responsive and handle multiple resolutions better and with ease

[torn shuttle]

to be fair you can buy specialized monitors that beat them in pretty much every aspect

they're just more expensive than a $90 lcd monitor

[wet breach]

Also because its an electron beam and not little crystals they can display shapes far better and accurately

[wet breach]

In theory assuming crt's are no longer produced this would be the case but electricity doesnt beat light or electrons in a vacuum

Downsides of crt is size and basically difficult to repair

[torn shuttle]

I don't think crts have any single aspect that they still hold over modern display tech unless you are looking for a balance that is struck only specifically by crts

[wet breach]

Now if you wanted to compare like a crt from the 90's with something modern sure we probably have some lcd that could beat it

[wet breach]

Modern crt displays can represent colors accurately as i said also their refresh rates are far higher then what lcd can do. Again comparing modern crt with modern lcd

[torn shuttle]

I mean, you can buy 8k monitors, you can buy 360hz monitors, you can buy monitors made specifically for color accuracy...

[wet breach]

Yes

Oh thought you asked a question lol

Anyways my point is. There is advantages to having a crt. Does that mean you should switch to one? Probably not lmao

[quaint mantle]

I though those still were drawing pixels

Of less colors

[torn shuttle]

no, I'm just saying there's not much of a market for them outside of retro / vintage right now, at least I've never heard of any other group purchasing new crts

[wet breach]

Medical, government, aero, space etc

[torn shuttle]

let's be real everything under gvt is not doing it because crts are good, they are often doing it to fix old systems which used crts and they are not about to update them

[wet breach]

Probably wont find much in the pure civilian consumer area except what you listed

[wet breach]

Uh no this far from the case. Old tech is sometimes better because new tech isnt needed nor provides any significant advantage

[torn shuttle]

yeah, that's called if it ain't broke don't fix it

you know what uses that logic? legacy systems

[wet breach]

Me being from military side i know plent of areas you could use newer tech but it wouldnt improve anything.

[torn shuttle]

if you're designing something new in 2023 you're not doing it with crts, least of which because they are getting harder to source by the year

[wet breach]

They are harder to source for civilian consumers

Not everyone else

[torn shuttle]

yeah for everyone else they're just more expensive

[wet breach]

Cheaper

[torn shuttle]

then you're getting scammed

[quaint mantle]

hey guys how do i make an action bar lasts forever?

[torn shuttle]

you'd pretty much have to reapply it even if it's just once in a while

[quaint mantle]

so make it return to itself over and over?

[wet breach]

Maybe outside the US. But us market this isnt true

[torn shuttle]

if that's a bad way of saying using a repeating task then yes

[quaint mantle]

okie then thanks ^^

[quaint mantle]

Create a task which repeats every 40 ticks (2 seconds)

[wet breach]

Anyways i am not trying to debate the market on them. Point i was making is they still have uses, they are still produced, and places still use them

[torn shuttle]

what economic sense does it make that a piece of tech that is used by an absolutely tiny proportion of the total global market is cheaper against one of the most mass produced things humanity is currently dishing out

[wet breach]

Well its only tiny to one area not the others

[quaint mantle]

is this correct?
https://paste.md-5.net/guyisacovu.css

[quaint mantle]

Nest your code

But yes

[wet breach]

Because one area doesnt need it as much all it did was increase supply for the others and thus keeps them cheap

They just dont need to mass produce them anymore

[torn shuttle]

I randomly opened aliexpress and I can buy 8inch lcd screens for 16 euros as a replacement for a samsung tab a 8.0 which should have a resolution of 1280x800 pixels which is an absolutely shockingly cheap price for display tech, and you're saying that you can source a crt for cheaper than these random sellers

[quaint mantle]

nest?

[wet breach]

Probably wouldnt be accurate to use tablets as a comparison

[torn shuttle]

it's just the display

which is just an led screen

[wet breach]

Yes but crts that small are niche and have been since the late 80's

[quaint mantle]

You have everything in one line

[torn shuttle]

sure, give me a size

[quaint mantle]

Nesting a code is splitting it in lines

Bukkit.getScheduler().runTaskTimer(plugin, () -> 
  e.getPlayer().spigot().sendMessage(ChatMessageType.ACTION_BAR, TextComponent.fromLegacyText("§aRoman§5MC!")), 
0, 40);

So it's a bit more readable

ohhh didn't know that nesting meaned that xd

Yeah, just avoid nesting it too much

cause errors don't worry

but thanks

[torn shuttle]

15.6 inches, random laptop monitor, 61 euros including european tax and it's 1080p

and I'm sure you could find cheaper if you weren't just opening a random link

[wet breach]

Well i am at work on mobile. If you dont mind i would prefer to use my computer lol. I will be home in like 7 hours

[torn shuttle]

I'll be long gone by then, it's 1 am

[wet breach]

Thats fine. I will just ping you

And you can read it whenever

[torn shuttle]

this man is out here pinging me awake to win an argument about how crts are cheaper

[wet breach]

Uh no not to wake you lmao

[torn shuttle]

I'll believe you that it is cheaper if it's leftover stuff the US looted from countries it had military theaters in post ww2

that's how the english got a lot of cool stuff for cheap

portugal too

[quaint mantle]

so luch has it the server had to many errors from that you know another way i can set it up?

[quaint mantle]

Which error?

it just caused issues with the sound i was running from it and just made both not work with just a huge error line so i made it into the first one i made and they both worked fine now

[quaint mantle]

question is getPluginDirectory remaned to getPluginLoader now?

[worldly ingot]

no

You probably are looking for getDataFolder()

It's always been named that though

[subtle folio]

How do I remove the message that gets sent whenever a player dies?

similar to changing the playerJoinEvent message to null, is there something like that for player death event?

[quaint mantle]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/entity/PlayerDeathEvent.html#setDeathMessage(java.lang.String)

Please read javadocs before asking

[subtle folio]

oh oops i forgot to cast the event thats why

thanks karmadev

[quaint mantle]

Np

[river oracle]

anyone have an idea on how I could unify these regex statements
<(.*?[\"])>|<(.*?)>
Basically goal is to match everything inside the tags unless they're in quotes e.g.

With just <(.*?)> this would match out
<example:tag:"<example>text"> -> example:tag:"<example

With my first statement though it correctly matches
<example:tag:"<example>text"> -> example:tag:"<example>text"

[echo basalt]

couldn't you just add a ? after your []

[river oracle]

no doing that puts me back to square one

[echo basalt]

this?

[river oracle]

yeah, but unfortunately that doesn't match tags with non quotes

which is why I needed the ore

[echo basalt]

why doesn't * work

[echo basalt]

I wonder if writing a string parser is more efficient tha nregex

[carmine mica]

you making a minimessage clone?

[slender elbow]

megamessage

[river oracle]

just need to adapt an implementation for BungeeChat

MineDown is nice and all but prefer the syntax of MiniMessage tbh

[slender elbow]

Keep in mind that MM is not regular so regex won't take you too far

[carmine mica]

🤮

[river oracle]

sure theirs more parsing to be done

was going to do it to grab the tags, but I guess I'll manually parse 🥲.

[river oracle]

granted I'm realizing since I'm simply adopting its syntax I don't need to reimpl all of MiniMessages features. Specifically some of the extra NBT stuff can definitely be left to a later date

[slender elbow]

I mean

"all of minimessage" is just mc components

[river oracle]

true, but for most use cases you really don't need all MC compoents in reality I really just need to focus down on colors, hover and some click events

[quaint mantle]

Does JUnit have an "assertNotThrows"?

[river oracle]

assertDoesNotThrow

[quaint mantle]

Don't exist

[river oracle]

it should

[quaint mantle]

My bad, I'm using JUnit 4.13.1

I'll try with 5

[river oracle]

https://cdn.discordapp.com/emojis/513348729110134785.webp?size=48&name=Shrug&quality=lossless

idk with 4

but it does on 5

[quaint mantle]

Yes, JUnit 5 has it

[river oracle]

🥲 my tokenizer works so far brings joy to my heart

legit so cursed thoguh 💪 but we ball idk how to fucking make a parser

[quaint mantle]

wdym?

[river oracle]

I'm making a MiniMessage syntax parser for BungeeChat

idk how tf to make a sophisticated parser I've never made one outside of some basic stuff like string splitting and a little regex

[quaint mantle]

Oh

[river oracle]

so I'm basically going from no knowledge to rocket science 🚀 but I have a feeling just like every crypto currency to ever exist I'm going to the moon babyyyy 🌕

[quaint mantle]

You might want to take a look at this?

https://github.com/KarmaDeb/KarmaAPI2/tree/master/KarmaAPI-Minecraft/src/main/java/es/karmadev/api/minecraft/text

Completely not sponsored

[river oracle]

why did you make your own chat components 💀

[quaint mantle]

I was bored

🗿

And phonk playlist started to play

[river oracle]

unfortunately my problem is a tad more complex than that

[quaint mantle]

My brain went brrrr

[quaint mantle]

Which is it?

Like, where are you stuck at?

[river oracle]

not stuck atm just balling. I'm tokenizing that shit up rn

e.g. you gotta put in your input string than tokenize the shit out of it

[quaint mantle]

I don't get what you mean

Kinda late, you better talk to me as a 2yo kid

[river oracle]

well when you tokenize a string you're essentially pulling shit out

[echo basalt]

Hmm should I make a reflection based packet system

So I don't have to do the BS writeUUID writeString stuff

[river oracle]

e.g.
<red>hi</red>
is extracted into 2 tokens
[<red>, </red>]

[echo basalt]

I just make a mapper function and scan classes

[river oracle]

on each token you store a bit more info e.g. 2 ints start and end location

[quaint mantle]

You could make it a regex

[river oracle]

sure but regex is slower

why do multiple loop when 1 loop work fine

[quaint mantle]

Multiple loops?

No

Loop once, replace and go

Let me explain

[astral pilot]

is there a way to have bukkit runnable executed at random tick intervals?

[river oracle]

even if you use regex you still are required to parse your tokens

I don't get how regex is any faster here

I could do a benchmark but its 11:05pm

whatever fuck it

[astral pilot]

anyone

[quaint mantle]

You are thinking about it as <red>hello</red> in red and <red>red</red> in red
The regex doesn't necessariliy need to go through all the match instances.

Make your regex like this:
\\<?<color>(red|blue|cyan|...)\\>\w+\\</red\\>

You parse that regex once, replace all the occurrences, and parse again, until you don't have matches/finds

[river oracle]

no

you'll have to wrap something that runs every tick and use Random

[river oracle]

cool but that regex gets crazy quick

[quaint mantle]

Create an scheduler, as a "main scheduler" which runs repeatedly, for instance every tick. Inside that scheduler, run another task which tick is a random number

[astral pilot]

ok i see thanks

[quaint mantle]

Not really
private final static Pattern COLOR_PATTERN = Pattern.compile("<(?<color>black|dark_blue|dark_green|dark_aqua|dark_red|dark_purple|gold|gray|dark_gray|blue|green|aqua|red|purple|yellow|white|reset)>", Pattern.CASE_INSENSITIVE);
🗿

[river oracle]

that's very legacy of you

are you forgetting everything components can support

gradients etc, hover and click events

[quaint mantle]

private final static Pattern CHAT_PATTERN = Pattern.compile("(?<container><chat\\s*(?<click>click=\"(?<clickAction>OPEN_URL|COPY_TEXT|WRITE_TEXT|EXECUTE)\"\\s*content=\"(?<clickContent>\\bhttps?://[-a-zA-Z0-9+&@#/%?=~_|!:,.;]*[-a-zA-Z0-9+&@#/%=~_|]|[\\w\\s&§]*)\")?\\s*(?<hover>hover=\"(?<hoverAction>SHOW_TEXT)\"\\s*content=\"(?<hoverText>[a-zA-Z0-9~@#$^*()_+=\\[\\]{}|\\\\,.?: -&§]*)\")?>(?<message>[a-zA-Z0-9~@#$^*()_+=\\[\\]{}|\\\\,.?: -&§]*)</chat>)", Pattern.CASE_INSENSITIVE + Pattern.MULTILINE);

Hover and click support 🗿

I said I went crazy

For gradients is eazy

private final static Pattern COLOR_PATTERN = Pattern.compile("<(?<color>black|dark_blue|dark_green|dark_aqua|dark_red|dark_purple|gold|gray|dark_gray|blue|green|aqua|red|purple|yellow|white|reset)|(?<gradient>#[0-9]{3,6}\:[0-9]{3,6})>", Pattern.CASE_INSENSITIVE);

I think this would work

[river oracle]

holy fucking regex

wonder how much slower that is than a simple if statement xD

[quaint mantle]

This takes <red>Hello I'm a <#fff:ff2fff>gradient

[quaint mantle]

It depends on how you use them

But what do you prefer?

Have like 50 if statements?

Or a single statement?

[river oracle]

Reminds me I need to turn my tokenizer into an iterator of sorts for true O(n) performance!

cuz rn It requires O(n^2) since I would parse my string twice

[quaint mantle]

Why would it?

[river oracle]

poor design I suppose?

ik I'm kinda doing it as I go here

?paste

[undone axle]

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

[quaint mantle]

cani see? 🥺

Holy, you read my mind?

[river oracle]

I mean for example here
https://paste.md-5.net/viboyicopa.java
You can just turn this into an iterator like system and only iterate through once parsing tokens as you go with a next method

as of now its a queue, but I'm going to switch that

switches generally compile into a lookup table so that option is still pretty good

[quaint mantle]

I guess OPEN is < and CLOSE is >

[river oracle]

yea

[quaint mantle]

Explain what would this code do to a string

[river oracle]

I could also use a map, but then I'd have to deal with hashing

[river oracle]

well it takes an input string and separates out every token. Ofc with this implementation than you would need to parse everything again

its about the same as this regex
((?<start><)(?<token>([^<>]+)|([^<>]+"(?<inner>[^"]+)"))(?<end>>))+?

[quaint mantle]

So it takes
<red>Hello</red> into
Token@red - Hello?

[river oracle]

major difference is its not separated into groups, however it can be done so pretty easily using iteration over separators :

[river oracle]

example

        String message = "<red>\"<Now>\"</red>";
        Queue<Token> queue = Tokenizer.tokenize(message);
        for (final Token token : queue) {
            System.out.println(token);
            System.out.println(token.details(message));
        }

Output:
Token[start=0, end=5, type=OPEN]
red
Token[start=12, end=18, type=CLOSE]
red

[quaint mantle]

Why is the text content between < >?

[river oracle]

I'm testing my escaping

as you can see its inside quotes

however, my current approach for that in of itself is flawed so it needs a little rework

[quaint mantle]

The problem with that is that you don't really know what that token is for. Like, it could be a color, an hover element etc, you will require tons of if statements for them

[river oracle]

I need to ensure the tag has been opened inorder for my quote escape to work

[river oracle]

sure but that's why I'm switching to a more Iterative design vs the current return of a Queue

so you can recieve a token and parse it and apply it to the next between it and the next token

[quaint mantle]

You will also need to add an error control. We all know the user does the possible to break the application, he might write <i love cats>Hello world!</what?>

What will you do in this case?

[river oracle]

nothing

[quaint mantle]

I mean, what will you do in your application to manage that case?

[river oracle]

String#startsWith

for the interior tag caluse

[quaint mantle]

For each case?

[river oracle]

there aren't many cases

you have to remember regex does the same exact thing

the only difference is its not frontword facing

[quaint mantle]

colors, hover components, click componentes (you can have both in one), gradients (as you mentioned before), title times, actionbars, contents of the hover and clicks

There're a lot of cases actually

[river oracle]

at the end of the day that's how many cases? like 30. If i wanted to hyper optimize I could use a Trie to filter out all non-keys

this would give a considerable advantage

seeing as Trie's refuse an input as soon as it doesn't match with the 30 or so inputs it would have

[quaint mantle]

so i am having an issue where the config yml keeps making this and not what i make in the code for it anyone know how to fix this?
https://paste.md-5.net/piwiqoyibi.makefile

[river oracle]

the downside is it slows down an actual match which is why IMHO it'd be better to just use the if statements and chance it on the bad syntax having to run through all of them

[quaint mantle]

I would use regex (as I did)

Seems simpler for me

[river oracle]

actually I had an idea with this

[quaint mantle]

?nocode

[undone axle]

It’s hard to answer a programming question without code
Oh no! You ran into a problem. But no worries, people are willing to help, but first they need to see your code. This is because otherwise, they would be providing help based on guesses instead of concrete knowledge. Whether it be a compile error, runtime error, or an unexpected output, I'm sure that if you were to provide code, you'd receive a quick solution.

[river oracle]

a Trie would be perfect here I would simply need to modify it to support proccessig the tag as soon as we know its valid rather tahn doing it again

[river oracle]

I couldn't be fucked tbh. We should benchmark our methods against eachother once I'm done :P might take a couple weeks though I'm a bit distracted of an individual

I also wanted to benchmark against MiniMessage cough my bad adventuretoo to see where I'm at

[quaint mantle]

Fuck yeah, let's do it

I didn't benchmark mine

Probably will get a surprise

[river oracle]

its pretty easy to do stuff with JMH

granted benchmarks take a long time

can be like 30 minutes xD

[quaint mantle]

Yeah, but I'm toooooooooooo lazy for doing things like benchmarks

[river oracle]

and you get to hear your computer die as JMH warms up the JVM

[quaint mantle]

No, I simply ignore it 🗿

As long as my code runs

[slate tinsel]

If I want to use "Bukkit.getServer().getOnlinePlayers()" but for all entities what is the easiest, do I have to first loop through all worlds and then loop through each world's entities?

[eternal oxide]

yes

but you will only be seeing entities that are loaded

[slate tinsel]

okey

[waxen plinth]

Bukkit.getWorlds().stream().flatMap(World::getEntities)

a nested loop works but I'm a streams addict

[slate tinsel]

I have made a code where I save entities in a list. If I check if this entity tries to damage another entity by checking that damager is this entity in "EntityDamageByEntityEvent" should this make it so that no entity can take damage from that entity?

[eternal oxide]

?tas

[undone axle]

https://tryitands.ee/

[quaint mantle]

hey, how does redstone work on spigot? So I have heard it skips ticks to optimise it for performance. So like, if i had a 0-tick pulse generator, could it like not activate every single time?

I know this is not a discord server for paper but, i am currently running a paper server. I have heard paper servers do TPS catchup to compensate for the skipped ticks, how does it differ from spigot? So like do they move updates to the next game tick or something?

[eternal oxide]

?fork

[undone axle]

SpigotMC maintains the Spigot server. If you are using a fork of Spigot (such as Paper, Airplane, Purpur, or other derivative works), you should seek support in the appropriate Discord servers.

[slate tinsel]

What I have experienced is that it has not worked, stupid of me not to say so in the question.

For example, I have entity as "FireRocket" but the player can still take damage from the explosion

[quaint mantle]

oh ok.

that is fine, but regarding the first question, can i know more about how it skips ticks?

[eternal oxide]

did you cancel the explosion event?

[slate tinsel]

yes

[eternal oxide]

as far as I know it doesn;t skip ticks

however I doubt you can have a zero tick pulse

[quaint mantle]

i have heard literally everyone say it breaks redstone probably.

[eternal oxide]

a pulse requires a down pulse

you can;t pulse up if you never pulse down

ie a zero tick pulse of power level 8 is just going ot give a constant level 8 signal

[eternal oxide]

explosion not damage

[slate tinsel]

or not explosion event just EntityDamageByEntityEvent

[quaint mantle]

this is the 0-tick pulse generator i am currently using.

[eternal oxide]

they are different damage events

[quaint mantle]

whats a pulse up and pulse down??

[eternal oxide]

if you have a pulse every tick there will never be a down time

[slate tinsel]

Can you retrieve the one that damaged or caused the explosion and make it so that no one is harmed by it even though it should still happen as well as the animaiton should be shown as well

[eternal oxide]

it will be a constant signal

[quaint mantle]

ah okay.

[eternal oxide]

yes, set the yield to zero

[quaint mantle]

0-tick pulses are actually one gametick perhaps, but they are called 0-ticks because of it being almost 0 redstone ticks perhaps.

dont entirely remember how they named this mechanic in redstone but is sometimes used for certain contraptions.

[smoky oak]

0 ticks are used to do stuff in one gametick that shouldnt be done in one game tick
like opening a 5x5 piston door

[valid burrow]

cancel damage and set yield to 0

and why would you need to retrieve the damager

but yeah with .getDamager i believe you get the exploding entity and with that you can get the cause

[slate tinsel]

Guess I should use the "FireworkExplodeEvent"?

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/entity/FireworkExplodeEvent.html

Or will it not work as I imagine?

[valid burrow]

are you only trying to cancel damage?

[slate tinsel]

Here's what I thought 🙂

[valid burrow]

@slate tinsel

[slate tinsel]

yes

[valid burrow]

cause in that case EntityDamageByEntityEvent

or something along those lines

[slate tinsel]

From a FireRocket entity contained in a list

[valid burrow]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/entity/EntityDamageByEntityEvent.html

[valid burrow]

yeah

[valid burrow]

use this

do

event#getDamager

and if its the rocket

e.setDamage(0)

[slate tinsel]

Okey

[umbral ridge]

hey so I forgot the most basic thing, when I do /setspawn, what could be the reasons that player isn't teleporting to the set spawn? Instead they teleport to a default world spawn?

Should I do setSpawnLocation() on a world? And if that's the case, what if player tries /spawn from the end or the nether, then I can't use setSpawnLocation()?

Should I teleport the player to spawn on PlayerRespawnEvent?

nvm 😣 https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/player/PlayerRespawnEvent.html#setRespawnLocation(org.bukkit.Location)

[valid burrow]

/setspawn is only for the player performing the command isnt it

[umbral ridge]

It's a custom plugin command

[valid burrow]

oh

okay

[umbral ridge]

is this supposed to be used?

[valid burrow]

from what plugin

[umbral ridge]

my plugin

[valid burrow]

well what is your current method that doesnt work

[valid burrow]

yeah sure

would work

no issues

[inner mulch]

is it possible to get the number that a player has set is fov to?

or even force the fov

[torn badge]

No

Purely clientside

[valid burrow]

no thats client stuff

[inner mulch]

ok

[valid burrow]

if you lucky you can give them slowness or speed to change their fov if they didnt disable that ig

thats about it

[umbral ridge]

is it possible to get the death reason (last harm reason) in PlayerRespawnEvent

[valid burrow]

i dont think so

just log it

hashmap

cache it until player respawns

then remove

[hushed spindle]

im trying to put a text placeholder on an item but annoyingly every time i rename an item or use /give to give myself an item with said placeholder as name it injects some color code on the 2nd character thats interrupting the placeholder

how does that work

[umbral ridge]

I can't do that. player could log out before clicking the respawn button, and on top of that, I could shut down the server and start it up again xD

so hashMap would be gone

[hushed spindle]

like i used the command /give @p diamond_sword{display:{Name:'[{"text":"<lang.material-diamond-dagger>","italic":false}]'}} 1 for example and still it puts that color code

same happens if i do it with code

[valid burrow]

well in case you need to put it in a database

but

cmon

its only respawn messages isnt it?

like

[hushed spindle]

or just put it in their persistent data container for the time being

remove it on respawn

[umbral ridge]

you can use that on a Player object?

[hushed spindle]

yeah

[valid burrow]

yeag

[umbral ridge]

how

[hushed spindle]

Player#getPersistentDataContainer()

[valid burrow]

the same as on any other entity

[umbral ridge]

damn thats easy solution then

tnx

[valid burrow]

player is a entity

[umbral ridge]

I though it was only possible for itemstacks

[hushed spindle]

nope entities got em too

tile entities too like chests

i think

[valid burrow]

yea

Items, entities, block entities, chunks, and worlds all have pdc

:p

Oh and structures

[umbral ridge]

So on PlayerDeathEvent, how do you get the reason why player died

[upper hazel]

hey why logic from inventory gui click does it apply to the player's inventory??

[young knoll]

You can get the last damage cause

[upper hazel]

how get slot from open inventory

[umbral ridge]

👌

[rapid trout]

I want to create customs GUI linked to a plugin, for that I will use shader but I'm finding 0 documentation or tutorial, someone know how that works ?

[umbral ridge]

what

[slate tinsel]

e.setDamage(0) and e.setCancelled(true)?

[eternal oxide]

if you cancel you don;t need to alter damage

[slate tinsel]

but if I didn't get it to work with cancel, then setDamage won't work?

[umbral ridge]

did you register the event

[slate tinsel]

ofc

[eternal oxide]

?nocode <-

[undone axle]

It’s hard to answer a programming question without code
Oh no! You ran into a problem. But no worries, people are willing to help, but first they need to see your code. This is because otherwise, they would be providing help based on guesses instead of concrete knowledge. Whether it be a compile error, runtime error, or an unexpected output, I'm sure that if you were to provide code, you'd receive a quick solution.

[slate tinsel]

will test once more if it doesn't work, you can see my code 🙂

[valid burrow]

i mean technically u can also cancel the whole event

doesnt make a difference ih

[valid burrow]

just add some print statements

maybe the problem is the way you check the damager

[molten hearth]

what is the best way to change a final field via reflection

FieldUtils.removeFinalModifier isnt available in java 12+ so idrk

do I downgrade to java 8 💀 🙏

[dry hazel]

none of them are good

your best bet is Unsafe

[slender elbow]

i mean

just setAccessible true should work on instance fields

[molten hearth]

yeah but i cant modify them if they're final

oh wait

sorry i misread

well

its a static final

[dry hazel]

theUnsafe.putObject(theUnsafe.staticFieldBase(field), theUnsafe.staticFieldOffset(field), value);

[half arrow]

Can anyone advise on how to get a paticualr head from https://minecraft-heads.com/scripts/api.php?cat= api? I can only seem to get a whole category back? for example I want a pig head?

[young knoll]

You can only get full categories

[dry hazel]

or more preferably, don't have a final field that you want to change

[molten hearth]

yea im using that rn

i think i changed the wrong field rofl

[half arrow]

Ah okay, is there another provider who does supply direct method to a head?

[dry hazel]

the supported solution would be stripping the modifier off in a transformer with a premain agent

[molten hearth]

nah its good it worked with unsafe

allat to change a char 💀 🙏

[dry hazel]

wouldn't the jvm just inline that since it's a constant

[half arrow]

Ok so on initial plugin load, call category GET if local storage doesn't exist already , store locally then when entity type is killed lookup in the stored data for that entity - sound about right?

[young knoll]

Sure

Or you could hardcode them all

[half arrow]

Ok might be the way to go

[umbral ridge]

how do you make a player lay down on the floor after they die? for a few seconds? what packets do i have to use or how do achieve this

[half arrow]

some of the default heads are way off the native mc ones for example pig isn't a regular pig head

[young knoll]

Well there is no "regular" pig head

[distant wave]

what does this mean?

[half arrow]

you know what I mean, the standard

[shadow night]

You could maybe send a player sleeping packet or something

[umbral ridge]

Do you know how to send a packet? I haven't done that before

[shadow night]

I haven't either

[umbral ridge]

😿

[dry hazel]

why not just asBungee().getColor()

[distant wave]

it returns java.awt.Color

not the bukkit one

[dry hazel]

likely that the awt color returns different values than the bukkit one expects then

[half arrow]

has anyone already done this? thats public - just thinking of time saving

[eternal oxide]

asBungee().getRGB() pass into Color

or something close

[distant wave]

just looked at docs and getRGB returns argb actually

[young knoll]

Vanilla Tweaks datapack has all the mob heads

[remote swallow]

is this not you coll https://github.com/Jishuna/JishLib/blob/master/jishlib-core/src/main/java/me/jishuna/jishlib/item/MobHeads.java

[umbral ridge]

aren't these basically textures?

nvm its an url part 👍

[half arrow]

Thanks guys

[young knoll]

Yes that is me

But those are only a few of the mobs

[half arrow]

Found something - Just need to go through and add textures i guess,

[slate tinsel]

Firework is an entity right?

[slender elbow]

not the JVM but javac lol

[eternal oxide]

yes

[slate tinsel]

ElgarL is "yes" to me? or is it to Emily

[slender elbow]

to you

[slate tinsel]

    @EventHandler
    public void onEntityDamageByEntity(EntityDamageByEntityEvent event) {
        DamageBlockedEntity damageBlockedEntity = getDamageBlockedEntity(event.getDamager());
        if (damageBlockedEntity == null) return;
        if (damageBlockedEntity.getEntity().equals(event.getDamager())) {
            event.setCancelled(true);
        }
    }

[eternal oxide]

do some sysouts to see where it fails

does it get a DamageBlockEntity?

[slate tinsel]

So it succeeds in running "event.setCancelled(true);" but the players still take damage

[brisk estuary]

is it possible to create a world that is just a cube and a structure inside it? I just need a structure in another dimension, but I don't want to create a whole flat world to do that

private void createBarooWorld() {
        World world = WorldCreator.name(WORLD_NAME)
                .generateStructures(false)
                .type(WorldType.FLAT)
                .createWorld();


    }
``` that's what I have right now

[eternal oxide]

put a sysout at the beginning of the event to see if it is firing more than once

[eternal oxide]

not in launch, sysout at top of damage event

[slate tinsel]

No, it doesn't run in the Launch event, it's just another event I have somewhere else in my code

[eternal oxide]

Do as I said

[slate tinsel]

i print in EntityDamageByEntityEvent

but i also have this i mine code:

[eternal oxide]

I can't help if you ignore me

[slate tinsel]

sorry, what should I do?

[eternal oxide]

put a sysout at teh top of the damage event so we can see how many times it fires

[slate tinsel]

okey, sorry :/

[slate tinsel]

i added "Log.info("DamageBlockedManager");"

[eternal oxide]

your logs look fine

[slate tinsel]

should I try with another event or something?

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/entity/FireworkExplodeEvent.html

[eternal oxide]

you can't get teh target with that event though 😦

[slate tinsel]

In this case, I only want to retrieve the entity that is "Firerocket" therefore no entity should be able to take damage from it

[eternal oxide]

your code is perfect, there has to be something else messing with it

another plugin uncancelling the damage event?

or somewhere else in your code you uncancel

EntityDamageByEntity is the correct event

[slate tinsel]

I only have my own plugin on the server, but can review my code and see if I've done something wrong elsewhere

[smoky oak]

unrelated question but i think i can interject here for a second
I've a small set of UUIDs that get adjusted when it's told to be adjusted (or gets regenerated), but potentially reads that set out much more often than its written to.
Is it better to use LinkedHashSets for very small (<200 entries) sets?

[eternal oxide]

Do you need it ordered?

[brisk estuary]

bump

[smoky oak]

no, i just need .contains

[smoky oak]

pretty sure you can tell flat worlds to generate with 'air' as its only layer

[eternal oxide]

just a basic hashset then

[smoky oak]

when should i switch in that case?

[slate tinsel]

This code checks that the projectile fired by the player does not damage other players, but does not see anything about it that could cause the problem. That is the only EntityDamageByEntityEvent I and the one in my DamageBlockedManager that we are trying to resolve now then

[eternal oxide]

switch?

[eternal oxide]

do you use any other damage event listeners?

[smoky oak]

use linkedhash instead of hash

[eternal oxide]

no point in Linked

[smoky oak]

thats for iteration then?

[eternal oxide]

uh?

Set has an iterator

[shadow night]

What is an "Iterator" object? Recently stumbled upon that in mcp

[smoky oak]

lemme find the conversation

guess this asnwers that question

some people might want to iterate over it though

whats the overhead of a LinkedHashSet compared to a HashSet? anything relevant?

[slate tinsel]

The ParachuteListener checks if a chicken is damaged

[eternal oxide]

Both are teh same (ish) speed but Linked uses more memory. So unless you need it ordered you shoudl use the simpler HashSet

[eternal oxide]

do any of your listeners setCancelled false?

[smoky oak]

like i probably dont, but this is for an api (would be accessible in classes extending it)
is iteration on HashSet not slower than iteration on LinkedHashSet? IkeVodoo said it is

[slate tinsel]

I've only used setCanceled true so far when coding with events

[eternal oxide]

no both are o(1)

[smoky oak]

I'm about 95% sure the best you can get for iteration is O(n)

[eternal oxide]

then I have no clue why you can;t cancel the damage from teh firework, unless fireworks are bugged

[smoky oak]

or do you mean the time to obtain the iterator

[eternal oxide]

in performance HashSet is slightly better as it only maintains one backing hashtable

[slender elbow]

"iteration speed" really does not matter

whatever you do inside the iterations is gonna be more costly

[eternal oxide]

^

[smoky oak]

thats a fair point, i just like keeping things like that in mind

[slate tinsel]

            this.fireworkEntity = this.victim.getWorld().spawn(this.victim.getLocation(), Firework.class, firework -> {
                FireworkMeta meta = firework.getFireworkMeta();
                meta.addEffect(EFFECT);
                firework.setFireworkMeta(meta);
                firework.detonate();
            });

            DamageBlockedManager.getInstance().addBlockedDamageEntity(this.fireworkEntity);

    private final FireworkEffect EFFECT = FireworkEffect.builder()
            .flicker(false)
            .trail(false)
            .withColor(Color.RED)
            .with(FireworkEffect.Type.BALL)
            .build();

    private Firework fireworkEntity;

[eternal oxide]

um you detonate before you add to your manager

MAY be ok as it won;t actually detonate until the next tick (probably)

[slate tinsel]

Regardless, something good to change, didn't think of it

[young knoll]

Wonder if you could just add pdc to it

or metadata

[eternal oxide]

it would be simpler to PDC

[slate tinsel]

That sounds interesting, actually thought about it before

[eternal oxide]

no manager then

[slate tinsel]

I made a utility for it which I then removed :/

[smoky oak]

how does suppress warnings work?

[young knoll]

It gets rid of the yellow

[smoky oak]

but not the warning?

so its useless then

[young knoll]

The yellow is the warning

[smoky oak]

it still is in the analysis

[quaint mantle]

The naming for them is so strange

It might be a capital D @smoky oak

[young knoll]

Could also just not use the deprecated event :p
