Its loginsecurity

And via plugins

And chatsentry

He using

Bruh i dont want illegal stuff i just wanted to give their old password

[round basin]

@fathom dirge

[mortal vortex]

and for what purpose?

[round basin]

I have my public lifesteal server

[mortal vortex]

Whats the purpose of needing to give someone their password? Have they forgotten it?

[round basin]

Not random people first i verify them

[mortal vortex]

Huh

Why do you want / need to see their password?

[round basin]

Like from when they join it show ip address of wifi or internet

[round basin]

To give them back their pass

[fathom dirge]

I just looked through their code and i can tell you with 100% certainty that the passwords aren't stored, only their hash value. So no way to get that old value unless you look through old logs where they logged in/ registered their password

[round basin]

How to see logs

[mortal vortex]

Why do you need to give them their password?

Did they forget their password?

[fathom dirge]

ServerFolder/logs

[mortal vortex]

If they forgot their password, then you can just change it for them?

[round basin]

There is not showing

[round basin]

But how i verify

[mortal vortex]

Why do you need to verify?

[fathom dirge]

The logs folder should be in the same folder your server.jar file is located

[round basin]

Bro if someone hack their account get try to change from us

[fathom dirge]

?

[mortal vortex]

So, reset the password

You're completely making some bullshit up right now

there is no genuine excuse to need to retrieve someone's password

[fathom dirge]

Yeah true

[mortal vortex]

Has someone forgetten their password? you reset it.

You're clearly up to something if you cant provide a decent answer

[round basin]

@mortal vortex are you idiot

Some randoms guys come to say reset my password without confirmation that doesn't his account

[mortal vortex]

And a random guy asking for someones password without confirmation isnt bad either

"idiot"

[young knoll]

Yo

Gimme your password

:D

[round basin]

@mortal vortex

Give him

[mortal vortex]

k

[round basin]

Give him password

Or die tmr

[glossy laurel]

any good, free dependencies for making npcs in order to avoid nms?

[sly topaz]

depends

if you just want NPCs that don't move, Lib's Disguises is usually a good option

[glossy laurel]

i want npcs that move

[sly topaz]

otherwise, you could meddle with Lib's Disguises + MobChipLite or Citizens

neither option is fun to work with

[glossy laurel]

😭

is nms easier?

[grand flint]

Why don't you use mythic mobs

[glossy laurel]

it supports human npcs?

[grand flint]

Yeah it supports everything

Mythicmobs + libs disguises is good

You can also use model engine for custom NPCs

Like custom models with texturepack npcs

[glossy laurel]

i just need players w skins

[sly topaz]

not really, no

[sly topaz]

would mythicmobs just be for the movement

if so, how easy it is to move entities in comparison to say, MobChipLite

seems like they just wrap a ton of the pathfinding stuff as well

[grand flint]

idk i just know mythiccraft has the best plugins

i mean from their wiki alone

ull see the quality

[thorn isle]

mythic is trash

but libsdisguises is definitely a good fit

you can use mythic for the mob ai if you don't want to do anything complicated with it, like just have it wander or stand still

[sly topaz]

I looked at its API the other day and I was expecting something more given the praise you gave it tbh

it isn't bad, but definitely could be in better shape

[thorn isle]

for anything more complicated you most likely want to control the entity yourself with the goals or pathfinder api

[sly topaz]

there's no pathfinder API in spigot 😛

gotta use MobChipLite

[thorn isle]

it's the least polished and most error-prone "large" public plugin i've ever used

and this includes slimefun

almost everything is broken or finicky in some way and the api documentation is in chinese

[chrome beacon]

I recommend just using Citizens

[sly topaz]

Citizens API is just painful

[chrome beacon]

🤷‍♂️ Haven't found it that painful to work with

[thorn isle]

i've never used it because i begrudgingly use mythic for my npcs

since all they do is stand around

[sly topaz]

Inventivetalent's NPC API was nice

too bad they aren't around anymore 😔

[thorn isle]

one of these days i will switch to something else however because even at this mythic sucks ass; the npcs randomly duplicate as mythic loses track of them and spawns new ones

[chrome beacon]

Time for Citizens

which many servers already have installed

[worthy yarrow]

That’s their fallback?? Just spawn new ones

[sly topaz]

I can't blame them too much for it, dealing with NPCs is just annoying

[thorn isle]

well it's not exactly intended for npcs or half of the other things people use it for, but you can get something similar by creating a spawner with a spawn limit of 1

[sly topaz]

but I do understand the frustration

[worthy yarrow]

Interesting

[thorn isle]

unfortunately in the area it is meant for, that is custom mobs, it basically has a monopoly

i say unfortunately because it's ass to work with api wise

[sly topaz]

https://github.com/InventivetalentDev/CompactNPCLib someone wants to give a go updating this, I'll forever be thankful

[thorn isle]

i've written a few addons and it's like having sex with a cheesegrater

[worthy yarrow]

Well now why do you know what that feels like o_O

[thorn isle]

obfuscated-nms tier "what does this do" "what is this" -> decompile and look around aimlessly until it starts making sense

[worthy yarrow]

I started working on wind mechanics for the frisbee physics, attached a vector to every chunk of the “arena” issue is that without a legit wind system, every chunk has a wildly different vector… should I just suck it up and make a proper system?

[thorn isle]

something something layered perlin noise

[worthy yarrow]

Eek

I was trying to avoid perlin for now until I felt like rewriting the generation

[thorn isle]

it's fairly simple in principle, you're already doing one layer of perlin noise (without interpolation) basically

what you do is you look at the 4 nearest chunks, get their random vectors, weigh them so the closest one has the highest weight, take a weighted average them

[worthy yarrow]

Ah yeah that would work

[thorn isle]

that gets you 1 layer of noise

you'll want to add a few more layers

[worthy yarrow]

I mean as far as I can tell, just a simple vector applies some nice looking wind effects

[thorn isle]

i.e. you add a second wind vector to say every 8th chunk. and then you take the nearest 4 of those, weigh them again, and add average with the 4 from the first layer

[worthy yarrow]

In terms of the frisbees flight anyway

I need to do bounce mechanics too smh

Well “skip” mechanics

[thorn isle]

just averaging the nearby vectors doesn't solve the problem that adjacent chunks will have wildly different vectors, it just makes the transition smoother

adding more layers means that the vectors are more locally coherent, i.e. the vectors in adjacent chunks are more similar

[worthy yarrow]

As it stands right now, you can throw about 6-8 chunks max so that actually sounds perfect

[thorn isle]

mmm i guess it depends on how noticeable the wind is

if the wind has a large effect and every chunk the frisbee goes through tosses it wildly in random directions, hitting anything is probably going to be impossible

[worthy yarrow]

Well when I turn up the impact, the disc gets crazy to say the least lol

I found a nice number for the outcome of the effect, being like .2-.7 multiplied by the frisbees initial vector every tick

Well not multiplied, rather applied based on initial throw direction against the wind direction

Skip physics though… I have a couple parts to this, based on the hyzer (angle) of the disc you’ll have more chance of the disc skipping off the ground on its first impact, basically have to write something like

Angle X * Velocity = skip power
Skip power * impact vector = final skip power
ApplySkip(finalSkipPower)

Still have to implement the angle modifier in the throw mechanic though

[pure dagger]

uhm, im doing black holes but its kicking players because flying is not enabled, i disabled gravity for them, is there somethin i can do or does the user have to enable flying on the server?

[worthy yarrow]

Attach the player as a passenger to a display entity and then just move the display

[thorn isle]

iirc that's a vanilla server feature that can be disabled in server.props or something

[worthy yarrow]

I assume it’s intentionally disabled

[thorn isle]

all it does i think is check if the player is not grounded for x seconds and not falling and kicks them

i think quite a few servers have it disabled because proper anticheat plugins exist and it has had odd false positives of players getting kicked when they stand on beds

that said the proper anticheat plugins will also most likely kick the players for flying or at least rubberband them back

[worthy yarrow]

Then yeah just put the player on a display entity

[thorn isle]

this'll add a bit of latency to the player controls (and you'll have to listen to the player input event to move the display around) but i suppose that does work

[worthy yarrow]

Visually will probably be smoother as well

I figure if you’re in a black hole you’re not doing much moving anyway lol

[thorn isle]

mmm i'm not sure

you're not in it yet, you're just getting attracted to it

[worthy yarrow]

Guess it depends what black hole is to kmys

[thorn isle]

there's the option of uh adding the levitation effect, but you can't really control how fast the player ascends with all that much granularity

[young knoll]

How did you disable gravity

I don’t know if the normal setGravity method works for players

But the attribute does

[pure dagger]

it worked

oh

yeah it owrked

idk how to do the mob riding thing, seems complicatd

[worthy yarrow]

Given that the player could move, I guess you could just let them do what they can until a point where you then attach to a display to visually display them getting sucked in lol

[worthy yarrow]

It’s not, how do you modify the players movement when they’re in the field of the black hole?

Cuz it’d be the same thing just to a different entity

But the player is a passenger so they also are moved with it

[young knoll]

But then they can’t fight it

[worthy yarrow]

.

There’s probably a point where you can’t

[pure dagger]

yeah, using vectors is better cause player can move in the opposite way to slow it down

[thorn isle]

you can listen to player input and move the display accordingly manually

[young knoll]

True

[thorn isle]

but this adds a little bit of latency and has other issues, like disabling knockback

[worthy yarrow]

That would be the complex part

[young knoll]

But it probably wouldn’t feel as natural

[worthy yarrow]

You know what a natural black hole feels like jish?

[thorn isle]

i think slightly trudgy movements inside the field of a black hole is probably fine, but the knockback is an issue if the minigame includes pvp

[young knoll]

Yeah

I visit them all the time

[worthy yarrow]

I’ll have to take your word for it lol

[young knoll]

Go decompile the old thaumcraft code and see what they did

Kek

[thorn isle]

alternatively, don't disable gravity but add the levitation effect with a level proportional to the Y component of the movement vector you want to add

[pure dagger]

also how to make entity unpushable?

do i have to use the event?

[pure dagger]

but gravity only works upwards

[young knoll]

Teams should work

[pure dagger]

oh.. i never used teams idk how that works

[thorn isle]

if you want the player to go down faster you can just apply a negative y velocity to them

[pure dagger]

/team modify lalala collisionRule never
thsi thingy? what do i do

[thorn isle]

if you want the player to go up you apply a levitation effect to them

[pure dagger]

but you were talkin about gravity effect

[thorn isle]

levitation

[pure dagger]

oh

[thorn isle]

as an alternative to setGravity(false)

[pure dagger]

can you add 0 levitation effect so player just levitates in place?

[young knoll]

I still recommend the attribute

[thorn isle]

i don't think so, but you can remove and add it every tick or every few ticks so the player approximately stays in place

[young knoll]

Assuming you are in modern version

[thorn isle]

that said the attribute/actually allowing flight for the player (with a slow movement speed) might be better at that point

that's basically zero-gravity and you can move in 3d

[pure dagger]

whats the difference between that and Player.setGravity

[young knoll]

I don't think the second one does anything

Idk though

[pure dagger]

but why doesnt the anti-fly system check if a player has gravity turned on

[pure dagger]

i used that and it works

i can show you my code

[young knoll]

Because it's bad

Maybe it checks the attribute

[pure dagger]

what about anti-cheat plugins

are they usually also 'bad'

and kick players when they gave gravity disabled

[young knoll]

One would hope not

[pure dagger]

ill test the attribute waittt

if (closestEntity == null) {
                onlinePlayer.setGravity(true);
            } else {
                Location entityLoc = closestEntity.getLocation();
                Vector vector = entityLoc.toVector().subtract(playerLoc.toVector());
                vector.normalize().multiply(0.1);

                onlinePlayer.setVelocity(vector);
                onlinePlayer.setGravity(false);
            }

also thats the code

it happens every 5 ticks

[young knoll]

Isn't that going to be the same strength regardless of distance

Because you normalize the vector

[pure dagger]

yeah

i guess thats what its supposted to be

[thorn isle]

i assume closestEntity only refers to the closest black hole rather than any arbitrary entity

[pure dagger]

yep

it only works if theres a black hole in 6 blocks distance

so its just sucking the same speed i guess

small black hole

[pure dagger]

it kicks me when i use the attribute too

[young knoll]

rip

[pure dagger]

so should i use the attribute over setGravity?

[thorn isle]

if it doesn't help, no

[pure dagger]

yay

[thorn isle]

you can try allowing and enabling flight for the player and setting their flight speed to something small

[pure dagger]

wait you could do that 😭?

[pure dagger]

oh i didnt understand .

[slate tinsel]

Is it normal that Bukkit#getEntity(uuid), returns null when doing that in the cosnumer that world#spawn() offers?

        return world.spawn(location, TextDisplay.class, textDisplay -> {
            textDisplay.setBillboard(Display.Billboard.CENTER);

            System.out.println("Is entity null? " + Bukkit.getEntity(textDisplay.getUniqueId()));
        });```

[sly topaz]

yes, the entity isn't spawned yet

[eternal oxide]

the consumer runs before the entity is added to the world

[sly topaz]

why would you use Bukkit#getEntity there though

[eternal oxide]

its purpose is to allow modification before spawning the entity

[thorn isle]

its purpose is for me to throw an exception in it and then catch it with a try-catch wrapping the spawn call, as a hack by which I can instantiate an entity without adding it into the world, without depending on nms

this is what it was added for

[slate tinsel]

Just for debugging this time, but I had an other method that I did call after this consumer, that used the entity instance from the class, but might just use the entity instance from the consumer then

[eternal oxide]

lol

[slate tinsel]

no wait, the uuid

the method did then use Bukkit#getEntity

I hated that method

So I will change it, it just looks better also

[eternal oxide]

wilmer, your textDisplay IS the Entity which will be added to the world. Its not there yet so you can;t fetch it

[sly topaz]

I can't imagine that actually works

[thorn isle]

it does

for now

just don't tell the paper nerds or they will patch it

[sly topaz]

someone should probably open a bug report about that lol

[thorn isle]

i will burn your house down

[sly topaz]

I couldn't care enough to open it myself, so you're safe

[slate tinsel]

Yeah, I believed it was something like that. But its fine if I change text and things for it in the consumer right (With the instance from the consumer)?

[sly topaz]

that said, isn't it easier to just spawn the entity through nms, it should just be an addEntity call

[thorn isle]

if i'm already depending on nms, yeah

but that has its own baggage

[eternal oxide]

Yes modify in the consumer

[slate tinsel]

Thanks 🙂

[thorn isle]

anything that doesn't involve world state is safe, like i don't think you can teleport it in the consumer; but anything that only changes the entity itself is fine

[young knoll]

That's what EntitySnapshot is for :c

[thorn isle]

did that pr finally go through?

i remember the paper nerds fighting it super hard

[young knoll]

It went through a while ago

[thorn isle]

or is that the one that doesn't let me get an actual entity instance that i can modify and pass on to protocollib to send entity update packets

[young knoll]

You can

[thorn isle]

neat

[scarlet shard]

Hey, I'm trying to load a world with only certain biomes for a gamemode I'm developing, how would you do that? I also don't want to generate any oceans, but they are generated despite removing the ocean biomes.

[pure dagger]

but can you even add players to many teams at the same time ?

[young knoll]

No

Only 1

[pure dagger]

doesnt seem a good aproach then

i just did vehicleMoveEvent

and teleported it bakc lol

[pure dagger]

can falling block chests contain items ?

saved

?

[chrome beacon]

yes

[pure dagger]

how

[smoky anchor]

My guess would be https://hub.spigotmc.org/javadocs/spigot/org/bukkit/World.html#spawnFallingBlock(org.bukkit.Location,org.bukkit.block.data.BlockData)

[chrome beacon]

No that doesn't contain the state

[pure dagger]

Location location = block.getLocation();
World world = block.getWorld();
BlockData blockData = block.getBlockData();
block.breakNaturally();
world.spawnFallingBlock(location, blockData);

i did this

doesnt work

[chrome beacon]

You might need to use NMS

[pure dagger]

oh

[chrome beacon]

I don't really see an API method for it

[pure dagger]

then i dont want

then

how to break it exacly like in creative, so the items from chest drop, but the chest itself doesnt?

[sly topaz]

You can do it with spawnFallingBlock no?

[chrome beacon]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/block/Block.html#breakNaturally(org.bukkit.inventory.ItemStack)

[chrome beacon]

I don't see a method that takes the block state

Looks like Paper has a method to set the block state though

Spigot does not

[sly topaz]

You can just listen to the EntityChangeBlockEvent or whatever it was called

[chrome beacon]

Yeah

you can do that

[smoky anchor]

just do /summon smh

[pure dagger]

but this also drops the chest??

[smoky anchor]

tfw commands can sometimes do more than the API

[chrome beacon]

it does?

oh well 🤷‍♂️

[chrome beacon]

true

[pure dagger]

yeah it just destroys it like in survival

i dont want to dupe the chest so it has not to drop

has to not drop

[smoky anchor]

I believe you could store the broken block pos temporarily in some set and then listen to the block drop event thing
there may be better way

[pure dagger]

i think ignoring it and just breaking entire chest will be better (not spawning the fallin block) cause the falling chest blocks are invisilble anyway

thatll be easiest

[chrome beacon]

falling chest blocks weren't invisible last I checked

[smoky anchor]

ye that was fixed I believe

[chrome beacon]

could be wrong though

[pure dagger]

i dont see it lol

im on 1.21

[smoky anchor]

wait, version ?

[sly topaz]

Does it? I can’t find it lol

[chrome beacon]

https://jd.papermc.io/paper/1.21.5/org/bukkit/entity/FallingBlock.html#setBlockState(org.bukkit.block.BlockState)

[sly topaz]

Ah, on the falling block

I was looking at the BlockData

[chrome beacon]

.0?

[pure dagger]

yes

[chrome beacon]

or what version exactly

[pure dagger]

oh

[chrome beacon]

but why would you be on .0 💀

[pure dagger]

the server is on 1.21.5

but plugin is for 1.21

[pure dagger]

i dont know

is there a list of blocks that can contain some items inside ?

[chrome beacon]

if it's a client rendering issue the client version matters

[pure dagger]

then 21.5

[chrome beacon]

• usually, assuming no protocol hacks

[chrome beacon]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/block/Container.html

[pure dagger]

oh thats an interface

[pure dagger]

do i just block.getState() instanceof Container?

[chrome beacon]

yeah

Do note that getState can be a bit intensive to run since it has to copy a bunch of data

[pure dagger]

so what

i shouldnt do taht?

or shouldnt i do that a lot

[chrome beacon]

closed as Working as intended on the bug tracker 💀

[pure dagger]

why do you send sad octopus emote

💀

[chrome beacon]

just try to minimize the usage of it

[pure dagger]

okay

does getBlockData return a clone?

[sly topaz]

You could say so, yes

[pure dagger]

why

[sly topaz]

BlockData is kind of a Block snapshot

[gentle inlet]

how can I cancel the book and quil gui opening when clicking a book as I did canceled the interaction event but it didnt work? I found closing the inventory worked but then there was a flash of the book gui

[chrome beacon]

You cannot

as you've been told before that menu is clientside

[gentle inlet]

but i was able the close it? so there isnt a way to remove the flash?

[chrome beacon]

The client accepts the close inventory packet for all inventoryies and menus

even the pause menu

[gentle inlet]

wait thats actly usefull

[smoky anchor]

if you don't want openable book & quill then you can use the item_model component on some useless item
assuming you're on some latest version

[smoky anchor]

literally how

I don't see any actual use case besides malicious

[gentle inlet]

what versions support that if you know?

[hidden wolf]

Does anyone use paper here?

[gentle inlet]

this is a spigot discord server if you want to talk about paper join the paper discord server

[hidden wolf]

Didn't know they had one 💀 thanks

[gentle inlet]

thank you

[dusky rivet]

How can I disable players from hitting if they have a bow in their hand? They can still shoot the arrow, they just can't hit a player with a bow in their hand.

[mortal hare]

did i broke type checking in intellij or smth

im using guava's loading cache and i want to cache null values also so i use Optional<> wrapper around objects just to cache null values, but i dont want to fire up cache loading mechanism for the first check since there might be already cached value

[remote swallow]

is the optional null or its contents null

[mortal hare]

optional

getIfPresent returns @Nullable T and T is Optional<Password>

this sounds counter intuitive from optional perspective to return null instead of empty optional

but its just how guava is laid out

basically i want to fire up cache loading mechanism only and only when optional doesnt even exist, otherwise read the value from the cache

if the cached optional is empty i want to invalidate the cache key to refetch the value

i want:

• Invalidate Optional.empty() (of typeOptional<Password>) if cache.getIfPresent(id) is not null
• If cache.getIfPresent(id) is null, fetch that value.
• If cache.getIfPresent(id) is notnull and fetched value is not Optional.empty() use that cached value in the method instead

i guess i can evade this warning by calling calling cache.get(), instead of cache.getIfPresent() twice by praying that implementation is not dumb enough to not notice reoccurring calls

but i guess it wouldnt work because if i call it twice i need to invalidate the cache somehow and that would call back the database twice for the same null value, if for the first time values wasn't cached

performance

[buoyant viper]

i think the issue is ur checking if the optional is null, which should always be false

u need if optional.isPresent

or ifPresent whatever

[mortal hare]

no you dont get it the returned value from cache.getIfPresent is nullable, and i've set the cache's generic parameter as optional

intellij just freaks out because it looks weird to do comparison with optional

but its completely legal in this case since i need to check whether optional object itself is null, i.e if the cache even held any value before

[buoyant viper]

ah

seems a bit odd to use an optional here instead of the actual type, but if u see the vision go ahead

[mortal hare]

    @Override
    public boolean login(UUID id, String password) {
        Optional<Password> optional;
        try {
            optional = cache.getIfPresent(id);

            // This is needed since Optional itself is nullable from cache.
            //noinspection OptionalAssignedToNull
            if (optional == null) {
                optional = cache.get(id);
            } else if (optional.isEmpty()) {
                cache.invalidate(id);
                optional = cache.get(id);
            }
        } catch (ExecutionException exception) {
            throw new AuthenticationException("Failed to check existence of authentication entry with id: " + id, exception);
        }

        Password validator = optional.orElseThrow(() -> new AuthenticationDoesNotExistException(id));
        return validator.validate(password);
    }

this seems to do what i need i guess

i love caches

right now

until i won't

🥲

but do i even actually need these checks? i mean login is not an write operation it shouldnt invalidate cache

cache.get() is more than enough imho

[slender elbow]

what even is the purpose of using an optional here

[mortal hare]

to represent non existant user authentication state

i lazy load whole user object on isRegistered() method call via the guava's cache

and then i reuse that cached object inside login method

saves sql bandwidth

[slender elbow]

i fail to see the usefulness of an optional here, you aren't really considering optional being a valid value so, why make it one in the first place?

or the usefulness of using getIfPresent either

[mortal hare]

look, i do have isRegistered() method which checks inside the database if user is registered or not by grabbing whole user object and putting it into cache, then inside login() i dont need to call database again since the object which was retreived via isRegistered() is already in the memory, thus i use Optional<> here. isRegistered() might result in empty optional if the user is not registered

[plush sluice]

hey. im pretty new to NMS and im getting that error when compiling, does anyone have answer to this? "cannot access net.minecraft.network.protocol.", im using

<dependency>
            <groupId>org.spigotmc</groupId>
            <artifactId>spigot</artifactId>
            <version>1.21.5-R0.1-SNAPSHOT</version>
            <classifier>remapped-mojang</classifier>
            <scope>provided</scope>
        </dependency>

[slender elbow]

but in either case, if it isn't in the cache or if it's empty, you're just recalculating the value, and if that returns empty, you're throwing an exception

i am not asking what isRegistered does or how it works for optimization purposes, i'm just questioning the use of an optional in a cache

[mortal hare]

that code example i've provided is kinda incorrect i've simplified it in to this:

    @Override
    public boolean login(UUID id, String password) {
        Optional<Password> optional;
        try {
            optional = cache.get(id);
        } catch (ExecutionException exception) {
            throw new AuthenticationException("Failed to check existence of authentication entry with id: " + id, exception);
        }

        Password validator = optional.orElseThrow(() -> new AuthenticationDoesNotExistException(id));
        return validator.validate(password);
    }

since login is readonly operation it shouldnt invalidate cache for no reason

cache is guava's LoadingCache

[slender elbow]

that looks slightly better, although I would throw the exception in the cacheloader and simply return the Password value when it's valid

[mortal hare]

that's low level repository class im handling the exceptions within AuthenticationManager class

[slender elbow]

what i'm saying is that you can make the CacheLoader for that specific cache throw the exception

[mortal hare]

yes but then it wraps into UncheckedExecutionException

[slender elbow]

unwrap it?

[mortal hare]

i want to maintain initial exception type for interface contract

[mortal hare]

why tho, that might incur instanceof checks for getCause() for no reason you can just place it outside cache scope

[slender elbow]

sure

you do it that way i suppose

i just wouldn't

if i know only one kind of unchecked exception can be thrown, then it's gonna be that

i don't see the benefit in using an optional

but if it tickles your braincells, go ahead

[mortal hare]

👀

[pure dagger]

can i just do this
Entity entity = world.spawnEntity(location, EntityType.FALLING_BLOCK);

instead of world.spawnFalling block?

like whats the difference

oh cause the falling block can have some data

, material

??

[sly topaz]

Yes

[pure dagger]

can i make furnace minecart invisible ?

[sly topaz]

Not sure, try it

[pure dagger]

but how

it not living entity

[sly topaz]

You can definitely hide it with the hide/show entity api

[pure dagger]

what is that

[sly topaz]

Player#hideEntity

[winter jungle]

Is there a way to change the title of a player's inventory?

[echo basalt]

The only way you can do this is by removing the inventory title on the user's lang

also your gui's a pixel off

[winter jungle]

yee i know xd

[winter jungle]

Sounds easy, thank you

[echo basalt]

Set it to " "

lang.container.title or something

[sly topaz]

now I can't unsee it

[winter jungle]

well its obvious xd

[echo basalt]

it's so noticeable fym

[winter jungle]

much better

[sly topaz]

I thought it was just a rounded corner from the preview

[young knoll]

Actually it was 2 pixels off

[sly topaz]

sorry had to do it

[chilly swallow]

When I open a chests inventory manually (using block state) it triggers the animation- is there any way to open inventory (not a snapshot!) without the animation?

[sly topaz]

you could get the BlockState's Inventory and just do Player#openInventory directly

[chilly swallow]

Thats what Im doing

[young knoll]

Isn’t that what they just said they did

[chilly swallow]

yeah it triggers the animation for some reason

[sly topaz]

didn't think that would trigger the animation

does just calling Lidded#close cause the animation to bug out?

I don't think there's any way to open the inventory without triggering the animation other than cloning the inventory view or something

[chilly swallow]

I did try that but it didnt seem to have any effect

[sly topaz]

what about a tick after

[chilly swallow]

I will give it a shot

Would the only other way be to intercept packets?

[sly topaz]

that's one way to do it, but if you're willing to intercept packets then maybe there's a NMS method you could call for it

[chilly swallow]

Well, I would use packet events to deal with packets, but I’ll have a gander into nms as well

[pastel nova]

Guys how do I set up worldguard properly? It seems like a bunch of plugins do the same thing and I cant figure out how to assign people in each plugin etc… i use LuckPerms for perms, WorldGuard for spawn protection and essentialX for commands

[mortal vortex]

What exactly are you asking?

You mean with the API?

[pastel nova]

nono

i mean I have to set up the permissions for each group but it seems like every plugin overlaps with each other someway

[mortal vortex]

This is #help-development

[pastel nova]

plus luckperms doesnt allow me to remove minecraft vanilla commands

[remote swallow]

if you want to remove a default allowed command give them the permission set to false

[pastel nova]

so i need to go to help-server

[pastel nova]

and i did, through the web editor

but that doesnt work, i set permission minecraft: false which logically should set all childs to false

[remote swallow]

thats not how permissions are formatted

[pastel nova]

but i still can use /tellraw, and vanilla commands

[mortal vortex]

https://cdn.discordapp.com/attachments/1376495143997145098/1376495198292414464/spigot-help-server.gif

[remote swallow]

you would want minecraft.command and set the field to false next to it not using a colon

[pastel nova]

it was just to set a point, I did do it through gui

[remote swallow]

there is also a chance that minecraft perms dont get auto expanded with a star

ex it should look like this on the gui

[pastel nova]

yeah i know, i tried both minecraft.* and minecraft

[remote swallow]

and make sure you saved/applied it too

[pastel nova]

mh lemme try again then

yeah that too, since im w bungee i had to set up a mysql container to share permissions, i though that was a problem but the connection worka

And i am part of the default group

[remote swallow]

do you have op by chance

[pastel nova]

yeah that was gonna be my next question

if op overrides any of this

[remote swallow]

in most cases op will override it

[pastel nova]

would it be "smart" to remove op from everyone and handle everything through lp?

[paper viper]

#help-server

Everyone has op??

[pastel nova]

ye sorry ill move there

[pastel nova]

ill answer u there

[buoyant viper]

yes, always work with the least amount of privileges required for any given role

ie. no one should have more permission than they will need, u can always modify it later of needed

[pastel nova]

yeah i figured, i just made default get rid of all permissions, and member will just use the one he needs

[buoyant viper]

intellij im gonna be honest i dont give a shit that im for (int i = 0; i < list.size(); i++)-ing instead of for (Type name : collection)-ing

[remote swallow]

im too kotlin'd

that java just looks weird to me now

[remote swallow]

maven smh

[buoyant viper]

i am workin on the shittiest algorithm known to man rn

[buoyant viper]

i tried making a project with Gradle Kt DSL and i couldnt get the Application plugin to work properly

[remote swallow]

bosh

[buoyant viper]

yeah i couldnt get workingDir to work

tried executableDir

[remote swallow]

smh

[buoyant viper]

didnt seem to launch in the right spot still

About to start a game design project for class, before I pick libGDX, does anyone have any personal issues with it? Like reasons I should avoid it?

I'm trying to disable logging of two of my plugin's commands. The command is logged in the console... {PLAYER} issued server command: /{COMMAND}.

I tried setting up a filter in the plugin's logger, but the command gets logged anyway. I want to disable it ONLY for my plugin, ONLY for '/register' and '/login' commands.

My current attempt:

private void setupCommandLoggingFilter() {
        getLogger().setFilter(new Filter() {
            @Override
            public boolean isLoggable(LogRecord record) {
                String message = record.getMessage();
                return !message.contains("issued server command: /register") ||
                        !message.contains("issued server command: /login");
            }
        });
    }

[sullen marlin]

Youd need to filter the whole server log4j logger

[empty heart]

How do i get the whole server log4j logger?

Bukkit.getLogger()

'getLogger()' is marked unstable with @ApiStatus. Internal

I'll try this

[warm mica]

Creating uis is painful af otherwise ots fun

[vital sandal]

I got this error when running Build tool

seemed that it cannot accthat the maven installation :l

although mvn already exit

[sullen marlin]

Looks like they deleted old maven from the server

I'll change the url, but you can set M2_HOME

[vital sandal]

I wonder why you just get the latest version automatically 🤔
LATEST_VERSION=$(curl -s https://maven.apache.org/download.cgi | grep -oP 'apache-maven-\K[0-9]+\.[0-9]+\.[0-9]+' | head -1) echo "Latest Maven version: $LATEST_VERSION"

[chilly swallow]

Just tried a tick after, and many ticks after and no luck. Thanks for your help!

[wet breach]

https://minecraft.wiki/w/Java_Edition_protocol/Block_actions

https://minecraft.wiki/w/Java_Edition_protocol/Block_actions#Chest

[chilly swallow]

Thank you 🙏

[wet breach]

would need to send that packet and set the number to 0

and then every 4-5 ticks

you would need to listen for that packet going out

and just modify it

as long as it is 0 the animation will not happen

the number represents the number of players looking in the chest

[chilly swallow]

Ahhhh okay

thanks so much

[wet breach]

[fallow storm]

So PersistentDataContainers you get directly from PersistentDataHolders can hold PersistentDataContainers. Is there a way for me to instantiate one of these containers? The actual PDC class is an interface and I don't know how to find what proper class the one I'm looking for is.

I want to store a new sub-container on an existing one

[young knoll]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/persistence/PersistentDataAdapterContext.html#newPersistentDataContainer()

[fallow storm]

Big thanks!

[sly topaz]

if you're making a PersistentDataType, you can use the adapter context from the method params of the fromPrimitive/toComplex methods

if not, then you can just take it from an existing PersistentDataContainer, however I'd encourage to make a custom PersistentDataType if you're trying to represent a class as a PDC

@fallow storm ^

reason is that a custom PDT encapsulates the serialization logic into a single class, which makes it easier to handle

[torn shuttle]

itch.io has a temporary outage

I get 4 support tickets

damn

[mortal hare]

oh wow intellij's terminal rendering had improved in recent versions

no more flickerry mess

nice

its as fast as native conhost

wow

now that i think off. isnt shading like a bad practice in terms of java development. i mean you can just load the libraries externally, by supplying .jar files and executing jar file by using runtime class path flag inside CLI: java -cp "libraries/* -jar app.jar

paper imho already does something like this where you declare dependencies inside plugin.yml and then it'll autodownload the dependency for you and put it inside libraries folder, that way you can reuse the same lib across different plugins, not sure if spigot does it

kinda cool

[young knoll]

You can do it with spigot

If it’s on maven central

[mortal hare]

why do people shade libs then?!

https://tenor.com/view/why-just-why-but-why-monkey-gif-13237413898749931576

[young knoll]

Not everything is on maven central

Also some plugins like to work on versions before 1.17

[mortal hare]

does spigot itself allow to specify custom maven repos?

[young knoll]

No

[mortal hare]

🤔

[torn shuttle]

if you don't package it then you can't be sure it will be in there one way or another

or that it will be in there with the version you want

shading guarantees you have the things you depend on in there in your own terms, unmodified

[mortal hare]

just run distJar inside gradle project and it will autozip everything under lib/ structure

you dont even need to have headache with launch scripts gradle autogenerates that for you

[true cosmos]

windows

[mortal hare]

i've tried to not use it

i cant escape it

sharex is too good

[paper viper]

Jars are meant to be portable and I don’t know if having to download a separate libs folder is really easy

[mortal hare]

you just .zip it

what's so special about it

[paper viper]

And then what would you do if it’s like a plugin

[mortal hare]

let the server software load the dependencies from repository online

just like spigot does

[paper viper]

If anything, downloading and loading dependencies is an anti pattern

[mortal hare]

how is that anti pattern

[paper viper]

Not only is it discouraged, but it’s actually against Maven TOS

[sly topaz]

shading isn't a bad practice at all

[mortal hare]

you can reuse the same lib across different plugins

[sly topaz]

it is just a form of distribution, the more well-known term is fat jars or uber jars

[mortal hare]

shading is kind of waste of space

[paper viper]

What if you have many versions?

What do you do

[sly topaz]

that's the static vs dynamic linking dilemma

[paper viper]

Yeah

[mortal hare]

you specify specific version

[paper viper]

And then… what?

[mortal hare]

i'tll load that specific version if it didnt had it it will fetch it

[sly topaz]

now, that is an anti-pattern

[paper viper]

yeah lmao

[mortal hare]

if two plugins use same version apache commons why does it have to shade the same shit

[paper viper]

the issue isn't that... it's if they are different versions

you should never ever be loading deps at runtime if anything

[sly topaz]

well, never say ever

[mortal hare]

lol, then bukkit plugins are antipattern

[paper viper]

they are

[sly topaz]

it is discouraged however people do it since it is convenient enough for the end user that one can deem it worth the hassle

[paper viper]

Yeah

[sly topaz]

the reason runtime dependency resolution is frowned upon is simply because it obscures what is required for your program to actually run at its full capabilities

[mortal hare]

that's what build systems are for. to declare runtime and compile time dependencies and build the packages which depend on them

[sly topaz]

declaring them at the build level isn't runtime dependency resolution anymore

[mortal hare]

this discussion tbh is worthless, there wont be any definite answer anyways. it it was we wouldnt have .exe installers, different package managers on linux and .AppImages or snaps or flatpaks

[sly topaz]

unless you do something like gremlin does which makes uses of the build script to declare them, but even that is more or less questionable design-wise

[mortal hare]

.dll/.so vs .lib/.a debate

[sly topaz]

I personally don't see worth on trying to save space just for the sake of it, nowadays it is free so unless you are in a constrained space or a dumb runtime that will attempt to load everything at initialization, it isn't worth the hassle

[young knoll]

Well you are constrained on space with spigotmc

[sly topaz]

I mean, define constrained

isn't the plugin size limit like 20mbs

[paper viper]

you arent constrained by spigotmc

just dont host it on there

or provide your own url

[young knoll]

No it’s like

4

[young knoll]

Well yeah

But shh

[sly topaz]

wow they really upped the bar for that huh

[paper viper]

or just like

host the releases on GitHub releases

lol

[sly topaz]

ig that's partly why md introduced the libraries block

[sly topaz]

eh, it's bad UX

most end-users don't know how to use github

[paper viper]

i have an actions that autobuilds so i'd prefer if ppl just downloaded there

[sly topaz]

even if you direct them to the releases page, they get confused as to why there's a zip on the download options

[paper viper]

i hate uploading JARs

[paper viper]

thats true lmao

[mortal hare]

if people dont know how to use github they shouldnt host their own servers

unless they're private

[young knoll]

Can’t you link the download directly

[paper viper]

you can't, i've tried

Even if you get the link to the direct JAR

It just redirects to the release page of that JAR

some proxy things

[sly topaz]

most people using spigot are hosting servers for their friends

anyone hosting a server seriously starts from somewhere, not necessarily by knowing how to use github

[paper viper]

you don't need any GitHub experience to host a server

[sly topaz]

if you have actions artifacts then you probably could link them with https://nightly.link/ for better UX

[mortal hare]

i wonder what file format should i use for my custom minestom server

im thinking of toml

but yaml and json seems fine too

[paper viper]

wait holy shit

that's really useful lol

[sly topaz]

it's better than trying to find the artifact on the actions tab, if anything

I know how to use github and I get lost myself there lol

[paper viper]

Actaully i cant use nightly link because I don't use upload-artifact in my workflow

[sly topaz]

well, use it 😛

otherwise your actions won't have any linked artifacts

I've seen some setups which use semantic-release-bot instead which is fine if you want all your builds to be permanent but it kind of clutters the release tab if you don't do semantic commit messages properly

[paper viper]

I use some random plugin https://github.com/PulseBeat02/mcav/blob/master/.github/workflows/tagged-release.yml

i just checked the repo and its unmaintained lmao

[sly topaz]

so that's essentially just the semantic-release action but worse

[paper viper]

Yeah

[sly topaz]

well, it at least doesn't clutter the releases tab by allowing you to just make all your releases the latest one

hey, as people say, if it works ¯_(ツ)_/¯

[paper viper]

thing is it doesnt provide a direct link

maybe i should just use a separate ci platform

to do everything lol

ive used circleci in the past but its ass

i should selfhost a jenkins instance

[sly topaz]

just use github actions upload-artifact + nightly.link

[fluid goblet]

i require help

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

;-; idk y but the setPermission no work

[sly topaz]

setPermission doesn't exist

[young knoll]

Now that’s a godclass

[sly topaz]

I can't imagine writting that much code without trying to abstract it out

not that they wrote it all, but still

anyhow, if you want to check for permissions, you have to check if the player has the permission at the call site

in this case, you'd have to listen to the item craft event and check if the player has the permission for your recipe, if they don't then you can just cancel it

Does not having a recipe discovered disallow you from being able to craft it? If so you could listen to the recipe discover event and then cancel that instead. However I am unsure of whether that's actually the case

[thorn isle]

https://github.com/Slimefun/Slimefun4/blob/experimental/src/main/java/io/github/thebusybiscuit/slimefun4/implementation/setup/SlimefunItemSetup.java

[sly topaz]

ah yes, hardcoding data in source code, so fun

what is SlimeFun even about

I know it has some kind of custom storage format which is a bit lighter than the normal one for minigames but that's about as far as my knowledge of it goes

[thorn isle]

you're thinking about the slime world format which is unrelated

[echo basalt]

think of industrialcraft but as a plugin

[thorn isle]

slimefun is more like an attempt at replicating some popular tech modpacks as a bukkit plugin

[echo basalt]

iirc they used armorstands to store data and it'd corrupt every othre day

[thorn isle]

to varying degrees of success

[echo basalt]

and it's all hardcoded

[sly topaz]

it isn't too bad that it is hardcoded to be honest

[echo basalt]

unacceptable

[sly topaz]

it means that it can be machine processed if someone gets annoyed enough about it

like, you could just parse the java code and convert it to a file format and then just modify the code to read that file instead, wouldn't be particularly hard to write a tool for

I assume that after you get all the hardcoded data out of the way, the rest of the code is way more digestable, though I haven't really looked at it

[thorn isle]

personally i don't mind the recipes being hardcoded since doing them in a non-source file wouldn't benefit for linting or autocomplete or anything else nice

but imo the recipes shouldn't all be hardcoded into the same class

[sly topaz]

I mean, you can defintely get all those benefits with the right format, but you'd have to create a scheme and the such so yeah, I get it

[sly topaz]

eh, if it is hardcoded, it hardly matters

[thorn isle]

it definitely matters, locality is important

[sly topaz]

they could use some help of indentation and comments to make separation clearer, but other than that

[torn shuttle]

if you have a finite amount of recipes it doesn't matter

[sly topaz]

I assume they allow you to add your own, but yeah

also having it as a format allows one to keep adding them fast as well, while having them in code means recompiling which can be annoying for something so huge

[thorn isle]

currently the item definition, i.e. the recipe, item stack, and behavior are spread in three different places; this class, the SlimefunItems god class, and then the SlimefunItem subclass for that item, respectively

this is ass

if it were up to me, it'd all be in the latter

[sly topaz]

Ig that's where locality would indeed matter, the fact that the class is so huge means that the code takes longer to compile lol

[thorn isle]

not just compile but to find or do anything with it

[torn shuttle]

if it were me it wouldn't be anywhere because it'd be getting anonymously initialized from config files but that's just down to how you want to scope things

[echo basalt]

not a fan of god classes

[sly topaz]

all of this said, I can't really shit on it

[thorn isle]

i can and i will and i have done so and will continue to do so

[torn shuttle]

they're fine if you have a finite project that does X thing and will never need to do anything more

[sly topaz]

it is very straight-forward code, even if not up to my standards

[true cosmos]

some1 mentioned god code and im piqued

[sly topaz]

I prefer straight-forward code rather than heavily abstracted code that takes me making diagrams on paper to understand

[torn shuttle]

I have some AI projects that just do one very linear task, basically a glorified script

it's just a dump with a single java class doing the entire thing

[sly topaz]

this would probably be a case where AI could help massively, though I doubt any current model has big enough context window to handle it lol

[torn shuttle]

gemini has a context size of 2 millin

more than enough for most spigot plugins

[echo basalt]

I remember seeing rumors that siri would be able to take user inputs and make shortcuts out of it

[ivory sleet]

no more AbstractFactoryFactory?

[thorn isle]

more input tokens means more money spent

[echo basalt]

effectively vibe coding

this feels like that

[torn shuttle]

gemini is free but yeah it costs google more

and boy

[sly topaz]

Inversion of control is my enemy

[torn shuttle]

I just get the biggest smile on my face every time I make a 1 mil token request to google

I love spending their money

[sly topaz]

I will never understand the obsession with that pattern

[thorn isle]

i'm a bit doubtful as to how long these free services will last but we'll see

[torn shuttle]

oh I'm sure they won't

[thorn isle]

doesn't seem like a very good business model

[torn shuttle]

I'm maximizing their costs as much as I can right now

[true cosmos]

local llms dont seem fast enough to code yet

[thorn isle]

throw more gpus at them and they'll become faster

[torn shuttle]

tbf though

give is what

20 years?

and everyone might have a top of the line model enterprise gpu in their desktop

[thorn isle]

but at that point you're better off just leasing compute

[true cosmos]

less accessible to low end computer use of like students and stuff who really deserve the ai

[torn shuttle]

plus 20 years of ai improvements

[thorn isle]

i'm looking forward to the asic's

[true cosmos]

On a desktop local is doable 96GB or 128GB RAM

[torn shuttle]

imo, fast forward 10 years and a lot of people will be able to run claude 4.0 thinking on their desktop

which would already be enough for a lot of things

[thorn isle]

prooobably

[torn shuttle]

(i'm talking in terms of equivalencies)

[young knoll]

Do not mention slimefun around me ever again

I will have an aneurism

[torn shuttle]

no joke claude 4.0 is already smart enough to make for some really interesting games if you just had free tokens

[thorn isle]

har har har

[torn shuttle]

but it's also insanely expensive

I think I have over $100 in api costs using it over the past 3 or so months

[thorn isle]

you've just got to optimize your usage and not send it 1 million token requests

[torn shuttle]

already have

[thorn isle]

not enough

[young knoll]

Optimize your usage to 0

[torn shuttle]

sure, judge something you know nothing about

[thorn isle]

try harder

[torn shuttle]

that seems reasonable

[true cosmos]

Idk how to get my agent to do a task for x time

[torn shuttle]

that's not how LLMs work, you give it a query and it replies, one time

you can make it chain in on itself if you want to

[true cosmos]

ive got it to chain enough to make a README of a codebase

[torn shuttle]

but that's just basically getting it to talk to itself and then putting an arbitrary end point

[thorn isle]

that's one thing i think inference providers should work on more, better integration of function/tool calls

[true cosmos]

it was accurate but pretty short

[thorn isle]

i think the openai realtime models did something like this but they were far too expensive at base for it to be useful

[torn shuttle]

most models only get 8k output tokens

even gemini which has 2 mil in

which is a major weakness

for a lot of stuff it simply is not enough

[true cosmos]

Yeah individual files never seem to get up to production size from prompting

[thorn isle]

i think this is mostly a limitation of the infrastructure the models run on rather than the models themselves

[torn shuttle]

I think it's both, models don't like it when they can talk for too long

that said some frontends clearly have workarounds for this already

claude can write 5 full classes of code with each more than 8k tokens in a single reply while the api can't

[true cosmos]

you're referring to claude code?

[torn shuttle]

claude 4.0 sonnet or opus

or 3.7 thinking

[thorn isle]

the thing is that this isn't really intrinsically any different from what we already do with them

[torn shuttle]

sure, mildly

[thorn isle]

take for example an openai function call

all it really does is append some new tokens at the end of the context and then resume inference

[torn shuttle]

there's the disadvantage that if it goes in the wrong direction you're just going to waste more time

but that's about it

I mean it's basically how deep research works and that's usually kinda fine

I wouldn't say it's faster at finding what I was looking for than I am, but I can just be working on something else while it's digging

also reminder we might already be in one of the best eras of AI because we don't have built-in ads in them yet

that's going to be something else when every platform has built in ads and you AI girlfriend really wants you to go out and buy a verification can of dr pepper

[true cosmos]

can't wait for NPCs

i noticed copilot has an npc vibe

[worthy yarrow]

💀

[true cosmos]

watching an npc just cleaning up streets

watching an npc play video games

[torn shuttle]

I mean

autonomous street cleaners already exist

and you can watch gemini, claude and uh

grok?

playing pokemon right now

[true cosmos]

yeah super fascinating to me

[torn shuttle]

o3 not grok

who knows maybe grok is also doing it somewhere

[true cosmos]

my test for them is to see which chemical compound is their favorite

chatgpt is the only one which wasnt a duplicate of the others but anyway the cool thing is them making creative decisions

[flat lark]

What would be the best way to receive one way inputs from a player. I was thinking of using conversations as all I need may be a input, int or such like that? but unsure of how retrieving the information after the conversation ended or timedout

[true cosmos]

i guess they're mostly utilitarian

[thorn isle]

what's your favorite chemical compound

[true cosmos]

myrcene

[thorn isle]

personally i'm quite partial to water

[torn shuttle]

caffeine

[true cosmos]

i would have said that 5 years ago

caffeine probably 4 y ago

[thorn isle]

after all i'm 80% water

[true cosmos]

today myrcene, tomorrow morphine

[thorn isle]

and i'm the best thing i know

[true cosmos]

i know them all i love chemistry

[thorn isle]

so water is at least 80% good

[torn shuttle]

you like chemical compounds? name every chemical compound

            @Override
            public String getPromptText(ConversationContext context) {
                return question;
            }

            @Override
            public Prompt acceptInput(ConversationContext context, String input) {

    }

[sly topaz]

sounds a lot like the Bukkit conversation API

too bad that doesn't work anymore

[flat lark]

Yes it is

IT DOESNT

Well dam.

[young knoll]

Since when?

[flat lark]

I'm using a GUI libary its just a lot of passing classes back and fourth and its a lot more work rather just asking for a simple int or input.

[sly topaz]

it's been broken for a while now, something something signed messages

[young knoll]

I swear I’ve used it post 1.19

[sly topaz]

or that's what I've heard to be fair, I haven't actually tested whether it actually works or not, maybe it just implodes under certain conditions

[young knoll]

Idk maybe I just made my own

Pretty easy to do

[sly topaz]

yeah, not particularly hard to be honest, it is one of these novel APIs from Bukkit which just didn't receive much love with the time

[sly topaz]

GUI libraries absolutely suck for this kind of model, yeah

most GUI libraries expect you to make an immutable GUI, so once it goes out of that then you're shit out of luck

if you want just text input, anvil GUIs usually are fine

[young knoll]

Or just wait for 1.21.6

Any day now

[sly topaz]

would also have to wait for spigot release

Sign GUIs too but they're kinda annoying in that they have to be within range of the player otherwise the sign GUI doesn't show

[flat lark]

Issue is with the one I'm working for has an issue with anvil stuff so I just decide to have one main ui. it passes new values to it and updates it

[young knoll]

I can smell that being very fast

Don’t quote me on that when it isn’t though

[flat lark]

Would you perhaps have the code for that and is it local to each player?

[sly topaz]

I mean, just listen to the chat event

[young knoll]

^

[sly topaz]

then build up your abstractions as you see fit

[young knoll]

I basically just use a map

UUID -> Conversation instance or whatever you want

[sly topaz]

the issue with using chat for input is that it breaks the chat chain so ideally you'd use commands but welp

[young knoll]

Chat chain?

[paper viper]

Oh yeah that…

Sends an error

[sly topaz]

it is a thing internally, whenever you report a message it sends the whole chat chain

[young knoll]

Ah

[sly topaz]

then again, I think that stuff doesn't work quite well on spigot? Or so I've heard so it is more or less a non-issue, for better or worse

[young knoll]

Idk I’ve never seen any issues in my test server

I don’t even know if anything is signed

[flat lark]

Couldn't I just use a command

[sly topaz]

you could indeed

[flat lark]

to trigger it

[sly topaz]

/reply whatever you may desire

[flat lark]

When they click on the GUI item it uses /triggerinput Int then have it use a timer to receieve an int input

[sly topaz]

usually going from GUI to chat is quite unergonomic

choose one or the other

what is it that you're actually trying to do anyway, we're discussing the solution without knowing the problem

what is that you have to input

[flat lark]

Stuff like name, interger related information, etc. I only need and input and int as the anvil gui for this library is not made very well and the creator documentation is a big vague on how to use it

[sly topaz]

couldn't you just use Spigot's API for the anvil gui

nowadays it just works with MenuType API I believe

[thorn isle]

i don't recall having issues with the conversation api, though i'm on paper and in offline mode

[paper viper]

You probably shouldn’t use the conversation API either way

[thorn isle]

is there something wrong with it?

[sly topaz]

I remember helping people having issues with it, however I don't remember what the issue actually was so it might just have been people using it wrong or whatever

it's been a while since anyone has asked anything about it

[sly topaz]

there's nothing particularly wrong with it, just hasn't received much love

[echo basalt]

uh

[sly topaz]

i.e. you can't really parse components with it and the like

but for basic stuff it is fine

[thorn isle]

it is a bit awkward to use but it's still marginally better than listening to the chat event or something manually

can the client even send components in chat?

i thought it was a plaintext string in the protocol

[sly topaz]

they can't send components directly, but usually people allow that by parsing format

[thorn isle]

i can just toss it into the minimessage parser or whatever if i need to, i think i already do that for player-placeable holograms

or no i think i use books for those

[sly topaz]

the one way they're allowed to send components is via tellraw but that is just awful for users lol

[thorn isle]

mmmm

[fluid goblet]

seems like set group works

[fluid goblet]

.

[mortal hare]

im thinking rn. aren't plugin config files with sensitive database credentials are kind of security hazard?

sure you can say nobody will reach plugins directory and steal that info

but you're storing passwords and other connection details in plain sight, hoping that some plugin exploit wouldnt allow you to read specific text files

one exploit to the plugins folder and bam your server data is completely leaked

[thorn isle]

filesystem access isn't any less difficult to get than e.g. being able to get the environment variables/system properties

you could maybe serve credentials from a microservice or something but all that really adds is security by obscurity

[sly topaz]

I already answered with what you have to do

[sly topaz]

.

[echo basalt]

if you can access the plugins folder you pretty much have an RCE waiting to happen

[mortal hare]

well dumping memory is harder to read than persistent credentials

[echo basalt]

ppl can upload a plugin and load it

then access the credentials in memory

or make a heapdump and upload to some server for later analysis

[thorn isle]

i guess you could set up a tunnel or a virtual private network in addition to the database credentials, and/or set up the firewall on the machine running the database so that only the minecraft server/plugin can connect to it

making the credentials useless

but yeah, by the time you get someone with filesystem access you are already fucked

[echo basalt]

even if you use environment variables nothing's stopping someone from loading maliious code and reading those

there's legit nothing you can do if someone acesses your file system

[thorn isle]

to be fair there is a difference between read and write access

read access could be much easier to get through some exploit in a plugin

[sly topaz]

I mean, just serve credentials through ephemeral methods then encrypt it like any authentication service would do

[thorn isle]

but my gut tells me it'd be just as easy to get read access to system properties

[sly topaz]

Ephemeral methods as in commands or console input if you can manage to do that in spigot console

[echo basalt]

only alternative is to run everything in memory straight off a image and dispose the VM after execution

still vulnerable to heapdump analysis

[sly topaz]

Heapdump analysis would be useless since it’d be encrypted

[echo basalt]

ppl are gonna reverse the encryption at some point

[thorn isle]

i mean ideally the credentials aren't the only line of defence to the database; you'd have a private network, or have it on the same physical machine with all ports closed, and a firewall

[sly topaz]

Just use a strong encryption algorithm and you’re good

[echo basalt]

smh

just do the AWS approach

[thorn isle]

muh quantum computers

[sly topaz]

Otherwise we’d be all fucked with all the database leaks that have happened over the years

[echo basalt]

crazy ass firewall and user management system

[sly topaz]

I believe following the standards web sets for auth is good enough

[echo basalt]

even if you have S3 creds you'll likely get blocked because it isn't coming from a specific IP

or domain or whatever app

[sly topaz]

Makes me wonder if one could make something like Clerk or Auth0 work with Minecraft plugins

Without having to interface it through some bs middleware REST API or something along these lines

Though I guess all these services offer is in fact just a glorified REST API with their SDKs so no way around that

[mortal hare]

but it reduces the risk of getting it exposed for example accidentally or through read excploit. RCE's require more knowledge about the server overall. Its just good practice to not save such things in .env or config files in either case since then you can easily revoke access or centralize management of credentials by external means, like through secrets manager

[flat lark]

Is there a way to do an instant callback with a method?

[sly topaz]

what does that mean

callback into what

[mortal hare]

maybe he wants CompletableFuture which is completed instantly

[sly topaz]

a completablefuture is completed instantly if you do it in the same thread

though at that point you just want a Consumer

[mortal hare]

CompletableFuture#completedFuture(U value)

sometimes you need glue code for async calls

[sly topaz]

fair enough

[flat lark]

https://gist.github.com/AvocadoVR/be52e91b223779eafc53c64e17a922b9

Using the CreateConversation method. I'd wanted to callback the value if of course they responded.

[sly topaz]

just use a CompletableFuture

I was extremely confused by your naming convention by the way

[flat lark]

Yeah, I was about to change it lol.

[mortal hare]

i bet he's c# dev lol 😄

[flat lark]

Yep

Lowercase methods drive me nuts

[inner mulch]

not really about minecraft, but what frameworks do modern java applications use for their ui?

[mortal hare]

its the opposite for me

D:

if i see pascal case i know its class/interface/record

in c# you have no idea

[mortal hare]

Swing, JavaFX

afaik Intellij uses Swing

JavaFX is kind of a bootleg react MVC but with OOP approach

[sly topaz]

@flat lark I feel like you're just recreating Brigadier

[mortal hare]

AWT -> Swing -> JavaFX. AWT is the most low level lib which Swing builds on top, and JavaFX build on swing on top

iirc

[inner mulch]

okay, thanks :)

[sly topaz]

is there a reason you couldn't just use commands, I feel like you could wrap the conversation around commands so you could take advantage of brigadier validation

although you couldn't take advantage of the client-side auto-completion that way but alas

[mortal hare]

AWT is basically "return me native UI, pls" kind of low level lib in java, meanwhile swing exploits that lib to render its own controls to make it look in OS independent way

[sly topaz]

JavaFX doesn't build on top of Swing

[flat lark]

I'm not entirely sure what you mean I'm not too versed in spigot functionality and networking is another ball game I haven't even understand yet lol

[sly topaz]

not for the most part, anyway

it is supposed to be a replacement for Swing

[sly topaz]

it doesn't really matter then

[mortal hare]

iirc implementation wraps around swing but i may be incorrect

[sly topaz]

there's some parts of it that has compatibility with Swing but that's about it

reason is that people were too used to Swing at the time so they had to provide some level of "backwards compatibility"

[mortal hare]

i guess you're right gpt tells me it wraps around AWT and not swing

https://tenor.com/view/primeagen-theprimeagen-gippity-chat-gpt-gpt-gif-10694526301644687231

nope

still wrong

found correct info on oracle site

[sly topaz]

@flat lark this is just a way to do it, so you don't necessarily have to do it this way but it keeps it simple enough:

public <T> void createConversation(
        Player player,
        String question,
        Function<String, T> parser,
        Consumer<T> action
    ) {
        UUID uuid = player.getUniqueId();

        if (awaitingInput.containsKey(uuid)) {
            awaitingInput.remove(uuid);
            player.sendMessage(ChatColor.RED + "You had an unfinished input, it has been cancelled.");
        }

        player.sendMessage(ChatColor.WHITE + question);

        awaitingInput.put(uuid, input -> {
            try {
                T value = parser.apply(input);
                action.accept(value);
            } catch (Exception e) {
                player.sendMessage(ChatColor.RED + "Invalid input. Please try again.");
            } finally {
                awaitingInput.remove(uuid);
            }
        });
    }

then you can do:

createConversation(
    player,
    "Enter a number:",
    Integer::parseInt,
    number -> {
        player.sendMessage("You entered: " + number);
    }
);

[mortal hare]

javafx has its own abstraction layer for OS controls called Glass

it doesnt use AWT for low level stuff

basically just shade javafx if you need to render stuff

[flat lark]

is this java or kolin?

[sly topaz]

java

[mortal hare]

java

[flat lark]

I was so confused by the :: making me seem to diff to me

[mortal hare]

its just static method reference

like passing function delegate through parameter in c#

[sly topaz]

method reference, stuff java 8 introduced to make the language a bit more functional

the other one is a lambda, but you probably already know that

[flat lark]

yeah

[flat lark]

Yeah, I'm going to use your method as its very better than mines!

[sly topaz]

weird, it should be able to infer there

[mortal hare]

just do (String input) -> {}

[sly topaz]

try replacing the input parameter with String input

yeah

[flat lark]

(uuid, String input -> {})

?

[sly topaz]

no, uuid, (String input) -> {})

probably doesn't need the parenthesis around the parameter but eh

@EventHandler
public void onPlayerChat(AsyncPlayerChatEvent event) {
    var player = event.getPlayer();
    var uuid = player.getUniqueId();

    var callback = manager.getCallback(uuid);
    if (callback != null) {
        event.setCancelled(true);
        // Run on main thread
        Bukkit.getScheduler().runTask(plugin, () -> callback.accept(event.getMessage()));
    }
}

this is how you'd integrate it to the chat event, you'd have to make a getCallback method in the ConversationManager which is just a getter for the map

you may also want to add a parameter to that method for timeouts and what not

[mortal hare]

i wonder if there's any attempt to try to provide bukkit api support in minestom lol
