[echo basalt]

But you can also inline it if there's no point in keeping it separate

[tawny osprey]

Yes

Okay

[remote swallow]

@worldly ingot do you need help

[worldly ingot]

?softban @shrewd dome Compromised account

[undone axle]

Done. Enough chaos.

idk if that was a comp account or just a very literal child trying to make money

Either way, it probably won't come back

[potent atlas]

Hi guys! I'm stuck on cancelling particle packets using packetevents. Can I share my code?

[violet blade]

sure

[potent atlas]

ok here is my main class https://pastes.dev/RfZdcM4VOc
and the listener https://pastes.dev/7UizooQKOK

The console doesn't show anything

No error, and no "Large smoke detected"

When I do /pl I can see both packetevents and my plugin, and there are no other plugins installed

[violet blade]

try maybe loading packetevents first then registering the class

[potent atlas]

k

No luck 🙁

[violet blade]

I've modified your code a little so that it simply gives me a packet dump, and I think the reason it doesn't work is because the smoke particles surrounding the blaze are only being displayed clientside. I'm only seeing particle packets listed in the console when I run the /particle command manually

-# This is just my speculation, I’m not entirely sure if this is 100% accurate

[potent atlas]

Ok, thank you very much for your help!

[acoustic shuttle]

Does anyone know how to make any block output a redstone signal?

I have only done some google searching and a few searches in the docs and didn't find much, most was from years ago where it apparently wasn't possible, anyway before I go on and probably end up spending a while trying to figure this out I just wanted to know if anyone here has the answer?

[thorn isle]

Yes, many particles are spawned clientside, the same applies to many other effects like sounds

[outer ember]

how to execute a command as a player BYPASSING their permissions?
(mention me im blind)

[chrome beacon]

You basically need to give them op or a * perm and then remove it again

Keep in mind that is quite risky

[outer ember]

it will be too broken

[thorn isle]

that's how it's done

it's not good but it is what it is

[chrome beacon]

Do use a try with finally block to ensure the perm is removed in case of errors etc

[thorn isle]

i don't think even luckperms allows for you to do anything smart with it

[outer ember]

I need to execute it as player

cause betterjails will send
masiha2ez jailed by CONSOLE
and yeah thats very annoying

[thorn isle]

smells very xy

[chrome beacon]

So this isn't a development question?

[outer ember]

Yeah it is

[chrome beacon]

But a betterjails question on how to get rid of that message

Move to #help-server or their discord if they have one

[outer ember]

i have to do one of this :
1.Make console name senders name
2.Execute as player bypassing their perms

[outer ember]

They doesnt have API

[outer ember]

How to at least do one of this

[chrome beacon]

Already told you what you need to do

If you want to write it in code

[thorn isle]

even if they don't have explicit api, you can build directly against their plugin to call whatever jailing logic they have

[outer ember]

giving them op makes plugin unsecure

[thorn isle]

well, you don't really have any alternative

[eternal oxide]

Looks like an API to me https://github.com/emilyy-dev/BetterJails/blob/v1/api/src/main/java/com/github/fefo/betterjails/api/BetterJails.java

[outer ember]

Wait WHAT

let me check

[chrome beacon]

Now the question is why are you running the command as console in the first place

[smoky anchor]

oh wait Emily made that one ? :D
Just ask her haha

[chrome beacon]

If you want to run it as a player just let the player run it?

She does lurk around here sometimes

[outer ember]

Ugh...
I was working a project to interact with betterjails and do some things but I found there was a easier way to do this
Now

[thorn isle]

does betterjails let me define jail sentences in terms of coal mined rather than time online

[slender elbow]

i should at least add support for indefinite sentence times rather than requiring a duration, that way at least one could hook up to it and do whatever other releasing requirements

my free time:

my time spent on discord: 💯

[young knoll]

Pfft, just set the duration to MAX_INT

Or long or whatever it is

[mortal vortex]

MAX_INT + 1 just incase

[alpine solar]

HUH

that's possible?

[worldly ingot]

I mean, it would just give you MIN_VALUE but yeah lol

[alpine solar]

o.O

[worldly ingot]

Numbers overflow if they run out of bits

What's 0111111111 + 0000000001? (Demonstrative, integers have 32 bits). It's 10000000000

[alpine solar]

📓 ✏️

okay, I have noted this

[worldly ingot]

Fixed my explanation. Negative bit is flipped, all other bits are flipped

Wait no I'm stupid

Give up

I know what I want to say

TRUST ME IT WORKS

[alpine solar]

I'm gonna give it a try

[misty ingot]

if choco says it works then it works
(it does work)

[alpine solar]

Oh, right

Hypixel dev, forgor

[misty ingot]

not just that
hes also an expensive bitch

so you KNOW hes smart

jokes aside i am pretty sure that explanation is infact how it works

[worldly ingot]

Definitely expensive

[alpine solar]

Wait

It's INTEGER.MAX_INT

right?

[worldly ingot]

Integer.MAX_VALUE and Integer.MIN_VALUE

[alpine solar]

Ah

Thought so and I changed it 😭

[hybrid spoke]

i always use MIN_VALUE as debug when only positive values are possible to be extra dramatic

[worldly ingot]

Which, by the way, in-and-of-itself proves that it's true lol

    @Native public static final int   MIN_VALUE = 0x80000000;
    @Native public static final int   MAX_VALUE = 0x7fffffff;

MIN_VALUE is 1 more than MAX_VALUE

[misty ingot]

i had to deal with an integer overflow very recently because one of our devs (me) was dumb enough to multiply two player-entered numbers without any checks
and that caused people to be debited negative money

[alpine solar]

-2.14, that's the output o.O

[worldly ingot]

Well, e31 probably, but yes

[alpine solar]

Which is MIN_VALUE, im guessing?

[worldly ingot]

Correct

[alpine solar]

oh yes

Alright Hypixel

I'm working for you next

With my string concat skills 😭

[misty ingot]

man i love bases
mostly due to their amazing uses

[alpine solar]

GENIUENLY, uni comp classes are so boring

[misty ingot]

i love competitive programming because those people find the best ways to do stuff
i just love looking into and understanding that stuff and seeing just how unintuitive or intuitive some solutions can be

[alpine solar]

Apparently, they dont teach you Java until you're 2~3 years in cause it's too "advanced"

[misty ingot]

sounds a lot like my high school experience

[alpine solar]

Which means, you'll have JUST 1 year to get completely familiar with it, before placements

😭

[hybrid spoke]

thats what LTS 25 is for

[worldly ingot]

For people that haven't touched a programming language, that makes sense. Python or Lua is usually the starting language

If they're insane, sometimes they start you out with C++

[alpine solar]

I started with C++

[worldly ingot]

My university's first programming course was C++ lol

[alpine solar]

And now they're teaching python

[misty ingot]

nah but in my high school we started python in 11th fuckin grade
and from my high school i mean every single school in the country that follows the same teaching board

[hybrid spoke]

c++ makes sense to get you close to the principles programming languages like java already cover

[alpine solar]

atp, ill be happy if I get placed in mcdonalds 😭

[worldly ingot]

And it's kinda like a scripting language until it's not

[misty ingot]

back when my brother was in high school it used to be cpp instead of python

[alpine solar]

Isn't python uhh

scripting language

[worldly ingot]

It's just the std:: in front of everything that confuses beginners with C++, which is fair. Modern C++ actually has an std::print() now though which helps a bit, but that would also require universities to catch up and teach modern C++

[alpine solar]

cpp isnt as boring as python

let's be honest

[thorn isle]

python makes me angry

[worldly ingot]

Python is an interpreted language, which yes you could describe as a "scripting" language

[alpine solar]

+1

[hybrid spoke]

no python no ai

[misty ingot]

i ignored everything tho and just kinda went my way

iirc I went python -> cpp(started competitive programming stuff) -> java(around the same time as cpp) -> lua

[alpine solar]

= no vibe coders?

which is nice

[thorn isle]

more like no python = ai that doesn't require the power consumption of 25 nuclear plants to operate

[hybrid spoke]

it's cool if you know what you're doing

[misty ingot]

cuz i learnt cpp to do competitive programming and not cpp itself i started out with std/bits so i didn't have to deal with that bs

[hybrid spoke]

like i can just be the architect and tell the ai what exactly i need in what way

[alpine solar]

can someone please save me from these python classes

please

😭

[thorn isle]

if the people working on ai didn't have the crutch that is python, someone would've done it in a real programming language instead

we probably would've sequenced the human genome thrice faster as well

[violet blade]

The thing of vibe coders is that most of them don't know what they are doing

[alpine solar]

They just type shi into chatgpt

[misty ingot]

this

[hybrid spoke]

that's the problem - not vibe coders per-se

[misty ingot]

and all of them think they can conquer the world
THAT part is the actual problem

[hybrid spoke]

i really hate the term vibe coders actually

[alpine solar]

"please develop me an anticheat similar to hypixel" 😭

it's funny how chatgpt interprets action events as uhh

for those

holdon, any anticheat nerds here

does it actually work through action events? or?

[hybrid spoke]

packets

[alpine solar]

yes but

is it like

[misty ingot]

i just realised this entire convo was in #help-development and not #general

[thorn isle]

it depends on the actual anticheat, but almost all of them listen to packets on the protocol layer at least to some extent

most also have at least some bukkit api listeners as well

[alpine solar]

ACTION.LEFT_CLICK_BLOCK, no right?

[hybrid spoke]

back in the days this was the general chat

[violet blade]

I'll spend 4 nights tweaking a promp in notepad just for the AI to hallucinate a complete monster instead of learning to code

And you will pay me 4000$ for it

[alpine solar]

I have $4 in my bank rn

[hybrid spoke]

oddly specific - it really depends. most of the times you just read the packets data and feed them into your algorithms

[misty ingot]

it still is

[hybrid spoke]

or as vcs2 said listen to bukkit listeners and interpret that data

[alpine solar]

oh, I didnt read his message

SORRY 😭

[hybrid spoke]

most of the time the chat looks dead ngl

[alpine solar]

nerd 🤓

[misty ingot]

if there is no item in hand it returns air right

because the item cant be null and the type cant be null so it has to be air right

[thorn isle]

depends a bit on the specific api method

many inventory api methods will return null for empty slots, many others will return air

you can generally trust the nullability annotations to figure out which is which

[misty ingot]

#getInventory()#getItemInMainHand()

[round finch]

how do you use non spigot plugin libs?
in your plugin?

https://tenor.com/view/calculating-puzzled-math-confused-confused-look-gif-14677181

i saw something about maven shading and ClassLoader too

[remote swallow]

shade it or add it to libraries field field in plugin.yml

[round finch]

is that the only right way?

[remote swallow]

unless its provided in the api or from mojang you have to provide it somehow

[round finch]

oh hold up what about the lib.jar?

where do i put it?

[remote swallow]

ideally you dont even reference a dependency from a jar, you should publish it to a repo or maven local and depend on it through your build system

[round finch]

then i build the jar
it just takes the lib source and put it into the plugin?

with shading right?

[remote swallow]

you should use the maven shade plugin and the right classifier to shade or use the gradle shadow plugin with the right scope

if its your own java lib you publish it to a repo or maven local and then reference it that way

[round finch]

alright
so shading is the way?

[remote swallow]

up to you, if its on maven central you can use the plugin.yml libraries field

[round finch]

thank you for trying to clearify it

[graceful laurel]

guys i need help ShadowJar doesnt work i dont if i did everything right 😭
https://github.com/ZoneXzzz/BeyonderX/tree/master

i dont see shadow jar or any shaded dependencies on that

or a valid plugin.yml for that matter

[mortal vortex]

group = 'org.example' (build.gradle)
actual package is src/main/java/com/jake/beyonder
lowercase class name (main.java)
two entry points
no spigot or paper in the build.gradle
massive amounts of code, with imports. That could not be written if no dependencies were given.

[remote swallow]

i did take a wild guess when i looked at the rest of the code

[mortal vortex]

obviously AI. no human writes that amount of code without having dependencies... Like how the fuck do you have import if you dont even have the dependencies to reference.

[alpine solar]

what's that 😭

[violet blade]

why is there a random empty main class lol

that’s what I mean 😭

It’s lowercase too

[azure zealot]

Does someone know the reason why in bungeecord plugin.getExecutorService is deprecated?

its deprecated since it was added

[chrome beacon]

Probably an internal, you should use the Bungee Scheduler API instead

[azure zealot]

Sadly its not documented

[chrome beacon]

the scheduler api?

[azure zealot]

no the getExceutorService method

[chrome beacon]

I see

[azure zealot]

every other method in the plugin class is

i was thinking about making the executor service a virtual thread executor service, its way better if you on java 21

[sullen marlin]

Ye should use scheduler

[azure zealot]

do you think we should check the java version an utilize a VirtualThread based ExecutorService for the scheduler if possible, should be much more efficient

[sullen marlin]

No idea

I am using this code to create a particle sphere that is shot from the player, but the problem i am facing is that there is a large delay, and then all the particles appear at once, instead of there being small delays in between. for (Location loc : locs){ Block b = loc.getBlock(); if (!b.isPassable() && !b.isLiquid() && b.isCollidable() && b.isSolid()) { if (b.getType() == Material.FARMLAND){ Farmland farm = (Farmland) b; farm.setMoisture(farm.getMaximumMoisture()); } break; } List<Location> sphereLocs = ParticleUtils.fibonacciSphere(loc, 0.75, 24); for (Location loc3 : sphereLocs){ loc3.getWorld().spawnParticle(Particle.WATER_DROP, loc3, 10); } for (Entity entity : loc.getNearbyEntities(0.75, 0.75, 0.75)){ if (!entity.isDead() && entity != p){ LivingEntity le = (LivingEntity) entity; double wandPower = NBT.get(wand, nbt -> (Double) nbt.getDouble("power")); le.damage(wandPower * baseDamage); Vector unitVector = entity.getLocation().toVector().subtract(p.getLocation().toVector()).normalize(); entity.setVelocity(unitVector.multiply(1)); } } try { Thread.sleep(50); } catch (InterruptedException e) { throw new RuntimeException(e); } }

[sullen marlin]

You cannot use thread.sleep in a plugin

You need to use the bukkit scheduler (google it)

The problem is you are pausing the server for 50 ms over and over and no packets can be sent

Each loc from locs should be a new task scheduled 1 tick later than the last, or 1 repeating task that steps through locs

[wide cipher]

ok, thanks

how can i stop the for loop from within the BukkitScheduler? I can't use break, nor can i create a boolean within or edit one within the lambda

nvm,

[wind timber]

Hi! Looking for advice on timing/ordering.

Goal
In a specific world, when a player breaks a crop we cancel BlockBreakEvent and send a client-side AIR update for X ticks (via a third-party networking layer, conceptually similar to Player#sendBlockChange). The real block is never changed server-side.

Observed
Immediately after the break is canceled, the client briefly renders the vanilla crop before our AIR takes effect. After that, AIR holds correctly.

What we already tried

• Listener at LOWEST with gating → cancel.
• Sending the client update in the same tick (scheduled on main) and also next tick.
• A short “suppress window” on our side so any immediate paint in the next few ticks should be treated as AIR for that index.
• No /reload, main-thread only.

Questions

1. Is there a Spigot-side pattern to guarantee that the very first render after a canceled left-click break uses our client-side state (AIR), so the vanilla crop isn’t shown first?
2. Would you recommend hooking an earlier event than BlockBreakEvent (e.g., PlayerInteractEvent with LEFT_CLICK_BLOCK) to push the client update sooner?
3. Is there any supported way within Spigot to veto/override a same-tick block update the server might send, even though the break is canceled?

Happy to provide a minimal repro if helpful.

[sullen marlin]

Why you cancelling the event then sending air anyway?

[wind timber]

Thanks for the quick reply!

In this world we don’t want the block to actually break (no world mutation, no drops/physics, multiple players can “farm” the same crop concurrently). Showing AIR is purely per-player feedback for a short window; later we re-spoof the player’s view back to the crop state. In other words: cancel prevents the real change, AIR is only a visual overlay for the breaking player.

The only wrinkle we’re trying to solve is that right after cancel the client briefly renders the vanilla crop before our client-side AIR takes effect. We already tried sending the client update in the same tick and next tick, listener at LOWEST, and a small suppression window on our side.

Any guidance on hook/priority/timing you’d suggest?

[wide cipher]

I'm using this repeating task now ``` int i = Bukkit.getServer().getScheduler().scheduleSyncRepeatingTask(Alkatraz.getInstance(), () -> {
List<Location> locs = ParticleUtils.fibonacciSphere(a.getLocation(), 0.75, 12);
for (Location loc : locs){
loc.getWorld().spawnParticle(Particle.WATER_DROP, loc, 2);

            }
            for (Entity entity : a.getNearbyEntities(1, 1, 1)){
                if (!entity.isDead() && entity != p){
                    LivingEntity le = (LivingEntity) entity;
                    double wandPower = NBT.get(wand, nbt -> (Double) nbt.getDouble("power"));
                    le.damage(wandPower * baseDamage);
                    Vector unitVector = entity.getLocation().toVector().subtract(p.getLocation().toVector()).normalize();
                    entity.setVelocity(unitVector.multiply(1));
                }
            }
        }, 0L, 1L);```

but am not sure how to stop the task if the arrow (a) hits the ground, any ideas?

[sullen marlin]

You can try a different event (ie interact like you suggest) or block the packet with a packet library. There's no API way to cancel the event but leave the client in the wrong state

[sullen marlin]

You can cancel task by the task id (i) as for the ground, you can use a projectile event

[wide cipher]

oh yea, thanks for the quick reply

[wind timber]

Hi guys , im new to this world...so i was thinking if some incredibly good person would like to help me get into the spigotAPI programing world with minecraft ? ( in vc or dm ) 👉 👈

[mortal vortex]

Do you want someone to hold your hand or do you have specific questions?

Do you know Java first? Probably learn that.

[dusk jetty]

how to hide the applies to: and ingredients: fields?

[worldly ingot]

I believe this is what you're looking for? https://hub.spigotmc.org/javadocs/spigot/org/bukkit/inventory/ItemFlag.html#HIDE_TRIM

[smoky anchor]

I think this one hides the trim from armor

I don't think the lore from Smithinkg Template can be hidden tho

[rotund ravine]

Not in latest atleast

[worldly ingot]

No, there's HIDE_ARMOR_TRIM that does that

HIDE_TRIM is for trims

[violet blade]

not really, since not so long ago that lore has become hardcoded

what you can do is hide the tooltip entirely but that wont even show the name or lore at all

[winter jungle]

Is the bungeecord repo dead?

[remote swallow]

still exists on the public repo not the snapshots repo https://hub.spigotmc.org/nexus/#browse/browse:public:net%2Fmd-5%2Fbungeecord-api%2F1.12-SNAPSHOT

[plush current]

I want to know how to add suggestion argument

for command arguments

[violet blade]

do you mean something like this?

[plush current]

yes

like when using that /give command it give suggestions like minecrft:diamond, minecraft:iron_ore

[violet blade]

That’s possible with brigadier, which spigot doesn’t expose directly, I’d suggest using an external command framework if you want to do that

[remote swallow]

you can have non colored ones, which would be always blue afaik from the bukkit tab complete methods

[plush current]

oh

[violet blade]

unless you want the simple List<String> that onTabComplete provides

[plush current]

ok

[winter jungle]

Thank you

[pseudo hazel]

yeah there is no way to hide it, since like you said its hardcoded in the client, so the only way around it is to set the trim as an item model for another item, especially if your application is for in a menu

[pseudo hazel]

so in short, you cant unless you dont use that item directly

but, like I said another item that you give this model to

[dusk jetty]

I got my answers in paperspigot discord

[tawny osprey]

I have a java related question. With lambda expressions, I know you have to declare the parameter(s) if an abstract method requires them, but do you have to use those parameters somewhere in the code block you provide as an implementation of that abstract method?

[graceful laurel]

how to i test my plugin aternos doesnt let me put my plugin in the plugin folder

[tawny osprey]

Local host

[graceful laurel]

how do u do that?

[tawny osprey]

Just search on youtube, local host minecraft server setup

Very convenient as well

[graceful laurel]

is ther papermc 1.21.5? i can only find 1.21.8

yall know how I can make directional particles with the cloud effect

nothing i am nothing is working; i'd them like to move upwards

[thorn isle]

not all particles support setting a velocity

what have you tried so far

iirc to set the velocity of a particle, you have to spawn them one at a time with count set to either 1 or maybe 0, and then the particle spread parameters are treated as a velocity vector

it would be very nice if it was documented somewhere in the javadocs, but i think the api method has parity with the ingame /particle command so you can check the mc wiki documentation for it

[timber eagle]

Yeah I've tried setting the offset Y to 1 and everything else is basically 0, speed and count. Also tried changing the speed but it didn't work

The cloud effect direction can be changed since other servers have figured it out somehow

[thorn isle]

how did damage events work with modifying the final damage again? i want to put a hard cap on damage per attack, but i want it to apply after armor, resistance, and other damage reductions have been applied

[rotund ravine]

What does the javadocs say

[thorn isle]

i don't know, the papermc javadocs are down

joking aside i can see that there's a getter for the final damage, but i don't see any way to set the final damage, only the raw damage

[timber eagle]

that is the final damage

setDamage sets the final damage to something. internally it has modifiers that it will go throuhg and reduce the damage

Here is the impl. for 1.8 (probably the same throughout most version)

public void setDamage(double damage) {
        double remaining = damage;
        double oldRemaining = this.getDamage(EntityDamageEvent.DamageModifier.BASE);

        for(DamageModifier modifier : MODIFIERS) {
            if (this.isApplicable(modifier)) {
                Function<? super Double, Double> modifierFunction = (Function)this.modifierFunctions.get(modifier);
                double newVanilla = (Double)modifierFunction.apply(remaining);
                double oldVanilla = (Double)modifierFunction.apply(oldRemaining);
                double difference = oldVanilla - newVanilla;
                double old = this.getDamage(modifier);
                if (old > (double)0.0F) {
                    this.setDamage(modifier, Math.max((double)0.0F, old - difference));
                } else {
                    this.setDamage(modifier, Math.min((double)0.0F, old - difference));
                }

                remaining += newVanilla;
                oldRemaining += oldVanilla;
            }
        }

        this.setDamage(EntityDamageEvent.DamageModifier.BASE, damage);
    }

[thorn isle]

right, i guess that makes some kind of sense, ty

[timber eagle]

yall know how I can make directional particles with the cloud effect
nothing i am nothing is working; i'd them like to move upwards

[thorn isle]

does what you tried work with other particles?

if all else fails you can use a network debugger on the client to dump the particle packets that other server you mentioned, and see what values they have

[timber eagle]

https://www.spigotmc.org/threads/comprehensive-particle-spawning-guide-1-13-1-19.343001/

its not working however

[sullen marlin]

Code?

[timber eagle]

One second im trying something

ParticleEffect particleEffect = new ParticleEffect(
                EnumParticle.CLOUD,
                player.getLocation(),
                0f,
                1.0f,
                0f,
                0f,
                0,
                1
        );

        PlayerUtils.EffectProcedures.sendEffect(player.getWorld(), particleEffect);

i have my own custom class

public ParticleEffect(EnumParticle particle, Location location, float xOffset, float yOffset, float zOffset, float speed, int count, int... data) {
        super(new PacketPlayOutWorldParticles(particle,
                true,
                (float) location.getX(),
                (float) location.getY(),
                (float) location.getZ(),
                xOffset,
                yOffset,
                zOffset,
                speed,
                count,
                data));
    }

the count is 0 and the thread says the extra data is the speed

which is 1

Alright so i managed to fix the speed, but it's colliding with the player

specifically the head

[sullen marlin]

Wdym colliding

[timber eagle]

So it's going upwards now but when the particle reaches the player's head its going back down

If I run it'll go straight up forever

I think if I just add some xz offsets it will fix

Okay nvm I don't know how the hell this works at all

but setting the y offset to 2 instead of 1 moves it all the way up

i dont think it was colliding i just think it was only going up 1 unit

but 2 makes it go up forever so.

Its fixed atleast

nvm idk what's going on

[plush sluice]

it has defeated me, i cannot teleport player to desired location somehow,
the location that im trying to teleport player to is good
Location{world=CraftWorld{name=world},x=0.5,y=90.0,z=0.5,pitch=0.0,yaw=180.0}

[eternal oxide]

reverse your guard clause. player is likely out of scope

[plush sluice]

code after teleport gets executed

normally

there was message after it but i removed it for screenshot

[hybrid spoke]

we need more context than this

[plush sluice]

Thats the problem

ITS THE WHOLE COMMAND

Nothing more

nothing less

just teleports player to spawn

its supposed to teleport player to spawn*

but doesnt do it

[eternal oxide]

change the guard clause.l Its failing on an invalid player field.

[smoky anchor]

no I think that works just fine

[violet blade]

Why final

[eternal oxide]

depends on teh IDE

I have had an out of scope field like that with it out of scope

its a simple change to test. So not like he has to jump through hoops to try it

[smoky anchor]

ye, fair

[chrome beacon]

that should be perfectly fine

[eternal oxide]

It "should"

[plush sluice]

it always does

[eternal oxide]

Eclipse will actually error on teh player field if you attempt that

[chrome beacon]

Eclipse moment

[plush sluice]

im using intellij

[chrome beacon]

That's fine then

[plush sluice]

i did it just for you
it sent me a message but didnt teleport me

before you ask

why player is underlined

[chrome beacon]

Why are you teleporting the player to itself?

[eternal oxide]

well yeah, you teleport to the players own location there

[plush sluice]

wait

wrong

even tho it was wrong and i changed it to this.getSpawnLocation it still didnt teleport me

[eternal oxide]

check your spawnlocation

sysout before it teleports

[plush sluice]

.

[eternal oxide]

sysout the actual spawn location you are trying to tp to. Before teh teleport happens

[plush sluice]

does it even matter if new location doesnt work?

funny thing is that in join event it works perfectly fine

[echo basalt]

Probably a bad command

Or it's running async

[plush sluice]

even if i do it in task it doesnt work

[eternal oxide]

you fixed your guard clause so there is nothing wrong with any of the code you have shown us

[plush sluice]

and thats why i came here, somehow it doesnt work

[eternal oxide]

you'll have to show more for us to see

[plush sluice]

theres nothing more

[eternal oxide]

There is no issue with spigot teleport so the issue is you

also, yeah why is player underlined?

[smoky anchor]

this apparently

[plush sluice]

yeah

[eternal oxide]

ah IJ being an ass

[plush sluice]

i always use finals wherever i can

[smoky anchor]

What you can do next is to just remove as much as you can - create minimal plugin where the issue happens
And share all the code

[plush sluice]

so i cannot overwrite crucial variables

[violet blade]

What commnd framework is that

[plush sluice]

my own, i just create command class and everything is being registered in spigot using reflections

[smoky anchor]

oh-

[plush sluice]

but still

everything works

and even if i teleport player in task it doesnt work

[young knoll]

Does the player have a passenger

[plush sluice]

nope

[young knoll]

Or is the player riding something

[plush sluice]

nope

[violet blade]

Try if it's working with commandexecutor first

[plush sluice]

or maybe

waaait

[young knoll]

[violet blade]

[smoky anchor]

Don't tell me that spigot can't TP that...
Why would that be a problem

[young knoll]

Spigot teleport doesn’t like passengers

[smoky anchor]

Why is this so outdated
It works fine in vanilla now
This is dumb

[young knoll]

https://hub.spigotmc.org/stash/projects/SPIGOT/repos/craftbukkit/browse/src/main/java/org/bukkit/craftbukkit/entity/CraftEntity.java#200

PRs welcome

[plush sluice]

thats the passenger of player

[young knoll]

Well there’s your problem

[plush sluice]

I spent WAY too much time on these few lines...

[violet blade]

Create your own tp logic by dismounting the passengers, teleporting all of them and mounting again

https://tenor.com/view/thinking-think-think-of-it-gif-12729650

[smoky anchor]

or call NMS teleport function
or dispatch /teleport

[plush sluice]

i just had to remove all passengers from player, they automatically respawn

[bitter spear]

Hey, I’m trying to create something similar to the bar mini-game from the CustomFishing plugin, but I ran into an issue:

my pointer is always being rendered under the bar instead of over it. I’m moving the pointer by adjusting the textures offsets. and I'm using a action bar.

Any ideas for a workaround?

[ancient plank]

this is what I did...

[echo basalt]

render the pointer after the bar instead of before

[fair igloo]

AnvilInventory.setRepairCost is deprecated. what do i use now?

[thorn isle]

there's a method for that on the anvil inventory view now iirc

[buoyant viper]

ye

[timber eagle]

Hey so I managed to figure out why it was acting so strangly

after looking in the MCP code

In the onUpdate method in the EntityCloudFX (cloud particle effect) it contains this logic

EntityPlayer entityplayer = this.worldObj.getClosestPlayerToEntity(this, 2.0D);

        if (entityplayer != null && this.posY > entityplayer.getEntityBoundingBox().minY)
        {
            this.posY += (entityplayer.getEntityBoundingBox().minY - this.posY) * 0.2D;
            this.motionY += (entityplayer.motionY - this.motionY) * 0.2D;
            this.setPosition(this.posX, this.posY, this.posZ);
        }

        if (this.onGround)
        {
            this.motionX *= 0.699999988079071D;
            this.motionZ *= 0.699999988079071D;
        }

[thorn isle]

that, uh

i'm not sure what that's supposed to achieve

[timber eagle]

thats why when i was jumping the cloud particles were like snapping towards me

downwards

i dont know why thats even a thing

[thorn isle]

i guess to send smoke signals with campfires...

stand on the campfire to back up the smoke and then step off to release it, or something

[timber eagle]

This is 1.8

but yeah

I don't understand still why there isn't an option to disable this (there probably is. i just dont know how)

this.posY > entityplayer.getEntityBoundingBox().minY

this is the line that causes me issues

because if the particle is above the feet it just falls back down

so annoying man

I finally figured it out; they use the explosion_normal enumparticle to produce the effects similar to clouds

[unkempt turtle]

Hello guys ! I'm trying to create circular borders like with custom textures like in that clip, do someone know how to do it ? I did not find anything : https://www.twitch.tv/sowolis/clip/HappyBreakableChickenMoreCowbell-dJ3Jei6t0ikO9CM_
Probably a block/item model inside a block/item display at the center which is then scaled (if the border is resizable)

Do I need to use BlockBench ?
I can do the model etc, I extracted it and tried but I still have rendering error ingame with black and purple block
I canno't find anything on the internet, not a single code anything
It is a circular border, with a custom design

[rough quartz]

🤣

[unkempt turtle]

?

[rough quartz]

funny name block bench

[unkempt turtle]

it is a software

[young knoll]

Might be some shader magic

[chrome beacon]

doubt it

probably just an item model

[rough quartz]

dows not sound like Minecraft name and another thing sounds like a windows program

anyway cya

[young knoll]

Item models can’t be circles

[slender elbow]

[young knoll]

Wait is it a circle

[chrome beacon]

it's not a perfect circle

[young knoll]

Or is it 22.5° angles

I can’t tell, too much movement

[chrome beacon]

yeah 22.5 angles is what it looks like to me

but true that there is a lot of movement

actually hmm maybe not 🤷‍♂️

[young knoll]

Wait can’t you do any angle from -45 to +45 now

Or -90 to +90, idk something like that

[chrome beacon]

haven't really kept up with that so no idea

[unkempt turtle]

[tall plinth]

Can we make this kind of gui in which gui elements changes using spigot coding if yes then how like which methods or what things to be used to make it

[sullen marlin]

Unless Minecraft has changed a lot in ways I'm unaware, that must be a resource pack

Possibly with villager trades, although that could be a bedrock screenshot

[tall plinth]

well its a screenshot from origin realms server

i just want to know how does the color of the trades changes according to the balance

[echo basalt]

Yeah that's doable with custom GUIs

I do this kind of menu at work

Let's say you have a fancy abstraction that involves "layers"

You have 6 layers for the 6 trades, a layer for the up button, a layer for the down button, and a background layer

You can use chat colors to tint the trade layer glyphs and/or hide them when you reach the bottom

and just change the glyph of the up/down layers based on if you can scroll in that direction

I also used that principle to do this kind of stuff

and I used a layer system for these guild uis

[unique linden]

Buenas nececito contactar con soporte

[tall plinth]

The up and down thing I can do that so is it even possible to set the requirements for the change of glyphs like hiding one and make another appear

[tall plinth]

Do you use any external plugin for it or you coded the plugin for gui

[echo basalt]

I made the layer system myself and I just tossed some placeholders at it

[tall plinth]

I see so you made a config.yml for it ?

or used a plugin like deluxemenu or Nexo or ItemsAdder

[echo basalt]

I'm using nexo for managing glyphs

everything else is custom made

[tall plinth]

I see got it

[echo basalt]

TIL that Map.copyOf doesn't copy the order of LinkedHashMaps

spent an hour tryna figure out why things weren't ordered

[tall plinth]

Damn

It took me literally hours to understand that it's fonts , glyphs and resourcepacks

[echo basalt]

and chat colors!

or for tinted items it can be anything but usually it's leather horse armor

with the attribute component hidden

[tall plinth]

Yeh bro that was a pain I was mad why the gui looked dark

It was literally white color code

which made the gui appear as it is

It took me literally 15-20 mins figuring it out

[echo basalt]

you could in theory take the dummy approach and make like 48 glyphs or whatever

[tall plinth]

Aaaaa nvm

Will go the smart way rather

[tall plinth]

There must be a tutorial about this and it will help many developers

[winter jungle]

I still dont know how the calculation works, i mean everything is at the title. But if my title gets longer the other stuff is moving to other directions, so i need to shift again yk?

[wet breach]

if someone was nice enough to make one

otherwise not really

[tall plinth]

If I guess it correctly then the layers work upon conditions like claim-1% , claim-2% so ig the title changes as per the conditions

that's why it's called title layers

It changes accordingly

That's my guess

[tall plinth]

Hm right

[worn tundra]

Welll, there kinda is here but its a little outdated http://resourcepack.wiki/

most of the font stuff still applies tho

[tall plinth]

I see

This failure was cached in the local repository and resolution is not reattempted until the update interval of spigotmc-repo has elapsed or updates are forced

it no longer exists as a 1.8 binary

build it yourself

There are alternate maven hosts supporting it. But nothing official

[outer elk]

how can i block this warn ?

Method invocation 'setExecutor' may produce 'NullPointerException'

        this.getCommand("icon").setExecutor(new IconCommand(this));```

[smoky anchor]

define the "icon" command in plugin.yml

[outer elk]

i did

wait

i will check again

ye

i define

like this

[smoky anchor]

oh wait it's just warning

[outer elk]

yep

[smoky anchor]

well either do nullcheck or just have the IDE ignore it

Objects.requireNonNull I think could work too

[outer elk]

what need i nullcheck ?

[smoky anchor]

this.getCommand("icon") is what is giving the warning

'cause it can return null

[outer elk]

    if (this.getCommand("icon") != null) {
        this.getCommand("icon").setExecutor(new me.vasir.commands.IconCommand(this));
    }```

[smoky anchor]

well no

make a var from this.getCommand("icon") and test that variable

[outer elk]

aah oke

[outer elk]

well im still getting warn

[smoky anchor]

show code

[outer elk]

maybe i need ignore

        Command iconCommand = this.getCommand("icon");
        if (iconCommand == null) return;
        this.getCommand("icon").setExecutor(new me.vasir.command.IconCommand(this));```

btw

tried var

[smoky anchor]

well you gotta use that variable

[outer elk]

wdym for "var"?

[smoky anchor]

Command iconCommand = this.getCommand("icon");
if (iconCommand == null) return;
**iconCommand **.setExecutor(new me.vasir.command.IconCommand(this));

[thorn isle]

the ide doesn't consider the getter to have a stable return value, so just checking that it didn't return null before isn't enough to assure it won't return null in the future

[outer elk]

ah

ahh xddxdxdxd

mbmbmb

[smoky anchor]

and don't return, do the if

[outer elk]

btw

there is no setExecutor method

after iconCommand

[smoky anchor]

sure there is
what did you do

[outer elk]

1m

[young knoll]

That's on PluginCommand

[smoky anchor]

oh bru

[young knoll]

and yes getCommand does return a PluginCommand

[outer elk]

        iconManager = new IconManager(getDataFolder());
        
        Command iconCommand = this.getCommand("icon");
        if (iconCommand == null) {
            getLogger().severe("error");
            return;
        }
        
        iconCommand.setExecutor(new IconCommand(this));```

is this right?

[smoky anchor]

Command iconCommand -> PluginCommand iconCommand

[outer elk]

ah

so you're talking about this

ookey

ty

[smoky anchor]

Also, I suggest learning java

[outer elk]

chatgpt helps

[smoky anchor]

no

man

[young knoll]

I mean the null check is really just to appease the IntelliJ gods

I usually ignore it

[smoky oak]

chatgpt can be used as an error checker a la 'list all errors you see'
for anything else its a bad idea to use imo

[smoky anchor]

        iconManager = new IconManager(getDataFolder());
        
        PluginCommand iconCommand = this.getCommand("icon");
        if (iconCommand != null) {
            iconCommand.setExecutor(new IconCommand(this));
        } else 
            getLogger().severe("error");
        ```

[outer elk]

i have an obsession

[smoky anchor]

again, do not return in that way

[outer elk]

avtually i think do this

w8

        PluginCommand iconCommand = this.getCommand("icon");
        if (iconCommand == null) return;
        iconCommand.setExecutor(new IconCommand(this));```

[thorn isle]

i'd just wrap it in requireNonNull since it's kind of a compile time/packaging error for that to return null

[smoky anchor]

omg return again
i'm done

[outer elk]

bro i really

[thorn isle]

no action other than exploding should be taken

[outer elk]

don't like

else if

[thorn isle]

chatgpt has melted your brain

[smoky anchor]

"don't like else if" wtf man

[thorn isle]

nobody is telling you to use else if, you're being told not to use return

[smoky anchor]

you'll suffer if you don't like the most basic flow control

[outer elk]

yes i don't wanna use else

the else statement after } is bothering me.

[smoky anchor]

then do this

[thorn isle]

are you getting triggered by a curly bracket

wait till you learn about anonymous constructors and instance initializers

[molten hearth]

wait till you hear about java syntax

[smoky anchor]

if (something)
doAThing()
else
doOtherThing()

Is also possible

no {}

(works only for one statement)

[thorn isle]

or god forbid if (something) doAThing(); else doOtherThing();

[outer elk]

why is this so important?

if you explain i won't do this again

[thorn isle]

((Runnable) something ? this::doAThing : this::doOtherThing).run()

[smoky anchor]

[smoky anchor]

Do you know what return does ?

[outer elk]

waaaitt

i understand now

how will it work if I add something else below?

xd

[smoky anchor]

yes

[outer elk]

i haven't been coding for 6 months.

this is the onEnable method

[thorn isle]

don't return prematurely from the onEnable method

[outer elk]

okey okey sry

ty guys sry again

[thorn isle]

if you do want to abort your onEnable midway, do so by throwing an exception, or disabling the plugin before returning

otherwise the plugin will remain in the enabled state despite being partially or completely nonfunctional

[smoky anchor]

thank you for putting my thoughts into words
it's hard when I'm in a work meeting :D

[outer elk]

ookey

[outer elk]

:((((((((( sryyy xddd

[echo basalt]

it returns null if it's not specified on the plugin.yml

I've had it error randomly as well

[plush current]

I usually use Maven to build my projects. Now I cloned a popular plugin, and I was wondering how to turn that plugin into a JAR file.

[vast ledge]

Does it not have build.gradle or a pom.xml?

[plush current]

yes

build.gradle

[vast ledge]

Send gh link

[plush current]

gh?

[vast ledge]

Then when you open the project in an ide it should say importing project

[vast ledge]

Github

[plush current]

Its a private repo

[vast ledge]

._.

https://docs.gradle.org/current/userguide/command_line_interface.html

[plush current]

@vast ledge i can send u the gradle code?

[thorn isle]

yeah and that's a packaging error, not really a "runtime" error in any real sense

[vast ledge]

Take a look at this, it's the docs for the Gradle cli

[plush current]

the files are correct, i just wanted to know how to convert it into jar file

[vast ledge]

You run the Gradle task

Usually clean build

[plush current]

on the terminal?

@vast ledge .\gradlew clean build
like this?

[vast ledge]

Try it

[plush current]

where will be the jar file generated?

[vast ledge]

It shouldve create a folder called build and a few folders inside that, look in there

Unsure of the direct path

[thorn isle]

by default in build/libs or something, but it depends on the script

[plush current]

👍🏻

its stuck in 18% execution

for 7m

[vast ledge]

Stacktrace?

[plush current]

but it didnt fail?

[vast ledge]

There should still be a log

[plush current]

no?

[thorn isle]

gradle is ass

[vast ledge]

If not it might just be that the project is large and takes a while to build. On Gradle the first build always takes longer, after the first build it's cached and goes faster

[plush current]

<==-----------> 18% EXECUTING [10m 20s]

Just shitty Internet then if it's been downloading 16mb for 7min

[thorn isle]

i've had it sometimes shit the bed waiting indefinitely on a repo that doesn't answer

[vast ledge]

xD

[thorn isle]

knowing how terrible mythicmobs is at making anything work properly, their repo could be doing something fucked

[vast ledge]

True

[plush current]

its the plugin Quests

[thorn isle]

sure but it's downloading mythicmobs

[vast ledge]

Yea, ur Plugin depends on the mythic mobs library

[plush current]

yes

[vast ledge]

So either ur network is slower then my brain or mythic mobs broke something again

[plush current]

😢

Its been 18m and it doesn't even moved from 18%

[tawny osprey]

is it really that bad?

genuine question

[slender elbow]

i mean, if it has to download a dependency to build, it can't just skip it lol

[thorn isle]

yes, their codebase is dogshit and everything they touch turns into shit

they do zero argument/parameter validation for anything, so things frequently explode with random npe's and undetailed illegal argument exceptions

and when they do, they never fail to swallow the exception message, and sometimes even the stack trace

half of their error messages are completely useless, like [MythicMobs] EntityType {0} does not support resetting AI selectors (they forgot to format it)

[plush current]

I’m new to server hosting and I want to create a Minecraft server hosting setup. Could someone please explain the process to me? Also, I’d like to know how much it typically costs when starting out. Any guidance would be really appreciated!

[smoky oak]

depends

do u have a spare PC? if yes, $12/year

also, lets move this conversation into #help-server

[nova notch]

get a raspberry pi for a small server

[slow leaf]

heck no

don't get a raspberry pi for your server unless your gonna daisy chain like 12 of them together to make them run as if they are one pi

[nova notch]

small server

cheaper than an extra pc

[slow leaf]

i mean for a small server

raspberry pi's aren't meant for regular minecraft servers, let alone a spigot or papermc server

[nova notch]

works fine for me with up to like 10 people

[slow leaf]

last time i tried to make a minecraft server one, it won't even get to world creation stage without just shutting off

[nova notch]

skill issue

[slow leaf]

not a skill issue when it was a 8gb raspberry pi 4 using an OS without an interface, just a command terminal, setup with a papermc 1.12 server jar without any plugins, set to 15 players limit and given 5GB of ram

as soon as it tried to generate the overworld, it would go black and i would have to turn it off and back on again to get any response from it

[lucid trellis]

Hi i've seen on a server the death message display only on death screen but not in chat and can't find how they did anyone have an idea ?? (might be packets but idk)
1.21.8 if you wonder

[young knoll]

[lucid trellis]

didn't work my event is setting the death message but its not displayed on death screen

Looking for help: eliminating a 1-frame vanilla crop flicker after canceling BlockBreakEvent (Paper 1.21.8 + PacketEvents 2.9.5)

TL;DR
Even after canceling the break, forcing client-side AIR immediately, and filtering/canceling outgoing block state packets, we still see an occasional 1-frame vanilla crop render on the target block. Has anyone fully eliminated this and can explain why that frame still appears?

Environment

• Server: Paper 1.21.8, Java 21
• Network hook: PacketEvents 2.9.5, PacketSendEvent outbound
• Goal: Virtual “farm” → the real world never changes; clients see per-player AIR for a short TTL on the clicked crop.

What we’re doing now (outbound order)

• Instant Air injection on LEFT_CLICK/BREAK cancel: send WrapperPlayServerBlockChange(AIR) to the player in the same tick.

• First-Frame Latch (per (player, section, index)): in PacketSendEvent we do Latch → Cancel/Filter → Overlay → Veto → Mask.

  • Cancel BLOCK_CHANGE when it targets the latched index.
  • Filter MULTI_BLOCK_CHANGE (remove only the target entries; cancel if empty).
  • Rewrite CHUNK_DATA per index (never cancel).

• Catch-up gating: defer sectionReady/overlay-expire a few ticks; overlay/veto TTLs increased.

Diagnostics (consistent across runs)
On the same (section, index) as the click:

[VF-INJECT] air-now … world=(x,y,z)         // same tick as click
[VF-LATCH] consume … index=…                // first Netty event on that index
// (only after this) RETINT-PE rewrite … on that index (if any)

We never see a vanilla BLOCK_CHANGE/MULTI_BLOCK_CHANGE landing before the latch; sometimes there’s still a visible frame on the client.

What I’d love to know

1. Is there any other server→client packet (besides the three above) that can cause an immediate repaint of the target block on LEFT_CLICK even when break is canceled? (e.g., some client-side effect tied to input, particles/animation, neighbor updates side-effect, or anything in 1.21.x?)
2. Is there a known client rendering quirk where the first frame is drawn from client predictions before any outbound packet, making a same-tick server fix insufficient unless we inject AIR even earlier/elsewhere?
3. Any proven recipe to guarantee the very first frame is AIR on cancel (Spigot pattern or caveat we’re missing)?

Any deep insight is appreciated!

[young knoll]

Doesn’t cancelling the break event send a block change to the client telling it to change the block back to whatever it was

[chrome beacon]

I believe so

The breaking is client predicted

[young knoll]

Yeah, if you listen for the packet that tells the server “Hey I broke this block” you can just throw it out

Otherwise cancelling the event is always going to try and correct the client

[wind timber]

Hey there! For crops (instant-break blocks), when we cancel BlockBreakEvent the server never sets the block to air so there’s no “revert” ClientboundBlockUpdate/BLOCK_CHANGE emitted by vanilla. In our traces the target block sees:

1. our nstant AIR (sendBlockChange/PacketEvents WrapperPlayServerBlockChange(AIR)) on the same tick,
2. then the first outbound on that index is our latch consume (we clamp SINGLE/MULTI/CHUNK),
3. only after that, any other rewrites.

We never observe a vanilla BLOCK_CHANGE or MULTI_BLOCK_CHANGE landing before the clamp on the target index, and we also don’t see BLOCK_BREAK_ANIMATION on the target (we log it).

Yet a 1-frame vanilla crop sometimes flashes client-side before any outbound is processed.

Questions:

• Is the client doing a left-click prediction that can render one frame on the previous state before it processes the first server packet—even if break is canceled?
• Is there any other server→client packet tied to the click (not state updates) that can force a block redraw on that position?
• Is there a known pattern to guarantee “first frame = AIR” on cancel (e.g., a recommended timing/earlier hook than BlockBreakEvent, or a specific order for sendBlockChange relative to Paper’s event lifecycle)?

[young knoll]

There should still be at revert

The server may never see air, but the client does

https://hub.spigotmc.org/stash/projects/SPIGOT/repos/craftbukkit/browse/nms-patches/net/minecraft/server/level/PlayerInteractManager.patch#218

[chrome beacon]

^ you cannot let it break on the client

[young knoll]

I think they want it to break

So they need to not let canceling the event send the “put this back” packet

[chrome beacon]

Ah I see

[young knoll]

There’s also the ClientBoundBlockChangeAckowledge packet

[chrome beacon]

Why'd you cancel the event then?

[young knoll]

Not entirely sure how that one works

[chrome beacon]

Nvm

I see

[young knoll]

They don’t want it to break on the server

[chrome beacon]

Yeah I saw their second message now

[young knoll]

Imo it would be better to intercept the break request from the client and discard it, and then do whatever you need from there

[chrome beacon]

Yeah just handle it on a packet level 🤷‍♂️

[young knoll]

Or rather, acknowledge the request but don’t let the server process it

(I’m guessing if the client doesn’t get the acknowledge packet it’ll revert the block itself? Not sure)

[wind timber]

Thanks guys, that clears it up. We’ll try handling it inbound so Bukkit never starts the break path:

Plan (PacketEvents 2.9.5, 1.21.8)

• Hook Play.Client.PLAYER_DIGGING.

• If action == START_DESTROY_BLOCK (and for instant-break crops also STOP_DESTROY_BLOCK?), in our VF world:

  • event.setCancelled(true) (don’t enter BlockBreakEvent at all).
  • Send immediate AIR to that player for the hit (x,y,z) (client spoof).
  • Seed our clamp (so any later outbound on that index is still forced to AIR).

Quick questions to sanity-check:

1. On 1.21.8, for instant-break blocks do you cancel only START_DESTROY_BLOCK, or both START and STOP (and maybe ABORT) to be safe?
2. Do you send anyting back after dropping the dig? e.g. a resync of the current block state, or ClientboundBlockChangeAcknowledge with the expected sequence or is no ACK the right choice so the client simply keeps our spoofed state?

[young knoll]

Not sure about acknowledging it

You could try both

[tawny osprey]

Do you guys use multiple threads often when you make plugins or nah

[ivory sleet]

Yes

Web api calls, databas calls, file io calls, sometimes even to do general work in the background like processing large sets of data

[vapid badger]

hi beggniner here,
when you register your commands and listeners do you do it in the main onEnable or you put it in a seperate class?

[drowsy helm]

usually just another method in your main class file

Try to limit onEnable to just invoking helper methids

[vapid badger]

great thanks

[vapid badger]

so leave it as bare as possible and mainly call other methods?

[drowsy helm]

Yeah, thats how I do it. Tends to be cleaner

initialiseManagers, initialiseCommands, etc etc

[vapid badger]

great thx

[wind timber]

Following up on my earlier question about handling inbound dig packets to prevent Bukkit from starting the break path. Thanks again for the clarifications, that part is working as expected.

Current setup (Spigot 1.21.8, PacketEvents 2.9.5):

• On Play.Client.PLAYER_DIGGING for crops in a specific world, I cancel the event so the server never starts the break logic.
• I spoof AIR immediately to the player, seed a clamp, and after ttl+1 ticks I send the original block state back using a MULTI_BLOCK_CHANGE (per-player only).
• Outbound, while the clamp is active, I force that index to AIR on SINGLE/MULTI/CHUNK packets.

Problem:
The restore packet is definitely sent (logs confirm correct spoof/vanilla state, sent via MULTI_BLOCK_CHANGE), but the client does not visually update the block until the player interacts with the world (right-clicking a block, placing, etc.). As soon as there’s an interaction, the block instantly appears as expected.

So it looks like the client ignores the update until it gets another trigger.

Has anyone run into this behavior? Is there a known packet or sequence that reliably forces the client to repaint a block in this situation? Would something like a section update, neighbor update, or block update flag be required instead of a plain multi-block change?

Any insights would be super helpful.

[wet breach]

could try sending this packet https://minecraft.wiki/w/Java_Edition_protocol/Packets#Chunk_Biomes

but yeah, its an old bug that persists in different ways between versions where you need to do something to cause the visual to update

[wind timber]

I was wondering if this could make sense https://javadocs.packetevents.com/com/github/retrooper/packetevents/wrapper/play/server/WrapperPlayServerAcknowledgeBlockChanges.html

[wet breach]

in older versions, you needed to send a chunk packet to make the client update the chunk

idk what that does

I don't use that stuff

[wind timber]

Why?

[wet breach]

most times, I have no need for it and second I don't mess with packets all that often either

[wind timber]

The system has to spoof thousands of farm crops per player (entire sections changing rapidly), so spawning and managing the same amount of block/item display entities per player would be too heavy on both server and client. With the current PacketEvents approach I can just mask indices inside section packets, which is lightweight and scales well.

[wet breach]

while true, the api you are using just makes use of what is present in the server

and a lot of times I don't need these large api's to do things

its fine if you want to use it, just I have no idea in relation to what you are asking since I don't use it

[wind timber]

No worries, appreciate it!

[wind timber]

This actually works btw!

what is mean by compile Folia to version 1.21.8

[smoky anchor]

Don't understand what you're asking & Folia is not Spigot, you're at the wrong place

[pseudo hazel]

to use buildtools to create spigot 1.21.8?

[timid mango]

How do I read the nbt of a player’s ender chest

And how do I write to it

[thorn isle]

paper supports this iirc

i don't remember if you can write to it

nevermind it was just for statistics and pdc

[violet blade]

modifying raw nbt?

[slender elbow]

why'd you need to do that?

just use player.getEnderChest() ?

[violet blade]

probably for an /invsee for offline player

[thorn isle]

i assume he wants it for offline players

[slender elbow]

i guess we'll never know

[thorn isle]

in fact i'm sure i read him saying he wanted it for offline players but maybe i'm going crazy since i don't see it now

i would maybe uh

depend on OpenInv

it has commands for viewing/editing the inventory and ender chest of offline players, i don't know if it has an api, but even if it doesn't you can probably hook into the internals to do what you need to do

i really would rather avoid trying to homebrew that on your own, there are many ways it can go wrong with e.g. player data being cached in memory even if the player is offline for a short period

[violet blade]

there is no safe way of doing it anyways

[thorn isle]

with enough hooking into nms you can make it safe enough i think, but i'm not sure if openinv does that

basically you'll want to call whatever logic loads the player data into memory normally, subject to whatever cache eviction logic is in place, then edit that and let autosaving deal with it

[violet blade]

yeah, well, its enderchest tho, even if the player gets on while you are accessing the data, he wont be rushing to open his enderchest

[thorn isle]

it's just that once the player logs on the data is duplicated from disk to memory, and that opens an avenue for items themselves to get duplicated

or lost altogether, for that matter

since the ender chest is part of the player data and gets loaded along with their inventory on join

[outer pond]

Not sure when this was changed, does anyone know how I can get my Spigot stuff deployed to Maven Central now?

[reef peak]

Hello

I unfortunately uploaded a wrong jar into my resource, can I replace it?

[rotund ravine]

Upload a new one with a higher version? And then report the resource letting them know of the issue. I haven’t used the resource system enough to know of how to remove one

[reef peak]

alright, getting issues with my update checker :
Versions depending link :
https://api.spigotmc.org/legacy/update.php?resource=127633 : v1.0.1

waiting

[reef peak]

Alright thank you

[graceful laurel]

can someone help me my plugin is 1.21.5 is there a way to change to version to the new 1.21.9 without redoing everything?

[smoky anchor]

just change the version in pom and fix compile issues if any exist and test it for bugs

why do you think you'd have to redo everything ?
The point of the API is that old plugins work for as long as possible (I think, it sure looks like it)

[graceful laurel]

where the pom?

[smoky anchor]

I assume you made your plugin with maven so it would be in the root directory of the project
if you used gradle.. I don't know gradle :D

[graceful laurel]

gradle

oh

😔

[smoky anchor]

ok apparently you go to build.gradle and change the dependencies

[graceful laurel]

oh okay tyty

Hey guys just curious, is it wise to use BukkitRunnable to set cooldown for plugins, or is there a "better" way?

[plush current]

how to generate a bundler jar?

of spigot

[sullen marlin]

?bt

[undone axle]

https://www.spigotmc.org/wiki/buildtools/

[sullen marlin]

java -jar BuildTools.jar ?

[sullen marlin]

Depends what sort of cool down. A hashmap could do

[plush current]

I correctly merged the Spigot repository into my branch. After that, I built the .jar file using the Gradle command: ./gradlew build -x test. I then placed the resulting .jar into my server folder. However, when I try to start the server, I get the following error: no main manifest attribute, in server.jar.

some one said that i need to have a bundler jar

[chrome beacon]

but why are you doing that manually

Just use BuildTools

[plush current]

I merge changes from another version of spigot from our server patches

[chrome beacon]

Spigot doesn't even use Gradle?

[sullen marlin]

Spigot doesn't use gradle, it uses maven

[worldly ingot]

Sounds like a slip up

THEY'RE USING PAPER! GETTEM!

[chrome beacon]

I do remember them mentioning Folia earlier

but then said Spigot when we said wouldn't give support

[chrome beacon]

[hushed spindle]

did the nms version of 1.21.9 change compared to 1.21.8?

or is it still R5

[eternal night]

Iirc it was bunped

[violet blade]

bunped

[hushed spindle]

it seems that it wasnt and we're still on R5

i think at least

[iron cave]

I thought nms version changes any time the protocol version changes

1.21.9 should be R7

[hushed spindle]

nms version has stayed the same since 1.21.6

being R5

[slender elbow]

it's completely arbitrary

[onyx fjord]

ConsumableComponent.Animation SPEAR is just a draft right?

[slender elbow]

draft?

it's the animation used for the trident item, for example

[young vine]

no its a coin flip

[tawny osprey]

Lets say a cooldown until you get teleported for example

[pseudo hazel]

yeah thats good

[hybrid spoke]

a hashmap with uuid-timestamp would be your best option

[tawny osprey]

thank you :))

[unborn hollow]

I'm getting "package org.bukkit.craftbukkit.v1_21_R5.entity does not exist" after updating my pom.xml to 1.21.9, did i do something wrong?

[hybrid spoke]

do you have spigot or spigot-api as a dependency

[unborn hollow]

spigot

[slender elbow]

it was changed to R6

welcome to nms

[hybrid spoke]

thats your problem, the package changes every 1-2 versions

[unborn hollow]

ty for the warm welcome, i'm definitely new to it haha

[unborn hollow]

good to know ty

[buoyant viper]

spigot

[unborn hollow]

mannequin.setPlayerProfile(player.getPlayerProfile()); didn't texture the mannequin with the player's skin. is this a bug?

[chrome beacon]

Is the player online?

[unborn hollow]

yes

[sullen marlin]

did you resolve the profile?

(.update())

there's a note in the release notes, but probably what needs to happen is that certain methods need to use dynamic rather than static profiles

or maybe profiles with no textures should just default to dynamic, not sure

[unborn hollow]

still didn't work

if by resolving the profile you meant

PlayerProfile playerProfile = player.getPlayerProfile();
playerProfile.update();
mannequin.setPlayerProfile(playerProfile);

[sullen marlin]

It's a future callback, you need a when complete or .then or whatever

And I'm almost certain it works because I tested it

[violet blade]

yeah this is working for me sorry i tried this with an already fetched profile, it wont work with a new player

[unborn hollow]

i'll try it again then, thanks

[unborn hollow]

when i run this exactly it just displays the default alex skin for me

[sullen marlin]

Because you're not passing a complete profile with textures

As I said you need to use a callback in the future, it's asynchronous

[worldly ingot]

update().thenAccept(profile -> mannequin.setPlayerProfile(profile))

Or I guess thenAccept(mannequin::setPlayerProfile)

[unborn hollow]

i'll try that choco thanks for explaining

[worldly ingot]

Futures and asynchronousy are hard
