How can I copy item's nbt using nms on newer version (1.21.x), previously on 1.20.x I could just do net.minecraft.world.item.ItemStack#setTag(CompountTag)?

eternal night
#

you can't

#

items in 1.21.4 do not have NBT anymore

#

outside of the custom_data component

summer scroll
#

So I just need to transfer the components instead of the nbt?

#

So basically I'm trying to sync inventories but I found a problem if the server version are different, on 1.20.x I serialized the item to base64 then deserialize it, it will work when I switch from older version to newer version, but not the other way around because downgrading item is not possible, because of that I decide to make my own serializer.

eternal night
#

How would that ever work

#

"your own serializer"

dense falcon
#

Alright.

eternal night
#

like, if you are just doing NBT instead of Base64, that won't fix it

summer scroll
lost matrix
#

I would just check out the nms ItemStack.copy() method

eternal night
#

what do you mean "the nbt too"

#

that is all the item is

#

its nbt

summer scroll
#

Sorry I meant like basically storing the nbt and then applying that nbt to the new item.

eternal night
#

That will not work when downgrading

summer scroll
#

But it works, was testing it on 1.20.4 and 1.20.1 server

eternal night
#

yea

#

because those versions have little to no difference

thorn isle
#

something something transmute

eternal night
#

it will absolutely not work when going from 1.21.4 to e.g. 1.20.4

summer scroll
thorn isle
#

ItemStack::transmuteCopy

eternal night
#

I think your entire approach is just flawed

thorn isle
#

applies the components of the item it's called on onto the item its passed

eternal night
#

1.20.4 to 1.20.5 will also e.g. not work

#

the only remotely sane approach here would be to write, what is basically a "reverse data fixer upper" implementation

thorn isle
#

what is he even trying to do

summer scroll
eternal night
#

I'm trying to sync inventories but I found a problem if the server version are different, on 1.20.x I serialized the item to base64 then deserialize it, it will work when I switch from older version to newer version, but not the other way around because downgrading item is not possible, because of that I decide to make my own serializer.

#

but not the other way around because downgrading item is not possible

thorn isle
#

yeah that's uh

#

well

#

you can look into whatever viaversion/viabackwards does

#

which is like driving the dfu in reverse somehow

#

beyond that, you're basically shit out of luck

#

if you only need lore/name/enchants + "nbt" as in the persistent data container, you can do the (de)serialization manually

summer scroll
#

damn, this is a tough one

thorn isle
#

why are the servers on different versions?

summer scroll
thorn isle
#

unless they are stupid they will have that in the persistent data container

summer scroll
thorn isle
#

skill issue

summer scroll
thorn isle
#

that stuff is now on the CUSTOM_DATA component iirc, which holds a nbt compound

eternal night
#

Via basically implements the DFU in reverse yes

#

well, on ViaBackwards

thorn isle
#

unfortunately from what i remember they don't have a convenient or even usable api to arbitrarily translate things back and forth

#

i had this magnificent idea at one point to write a very simple wire packets based plugin and then offload version compatibility to via

#

i would just write like 1.20 packets and via would update them to whatever the current version is, so it'd be maintenance free

#

but from what i remember trying to get it to work was like having sex with a cheesegrater

summer scroll
#

anyways, thanks for the help guys. from now on i'll make sure to use same version

``` I would like to disable interactions with Armorstand but the event is not called... Why?
eternal oxide
#

an Event not firing means you either didn;t register it or you are watching the wrong event

thorn isle
#

consider getting worldguard

dense falcon
#

It works, thanks!

quartz sorrel
#

I noticed that the CrafterCraftEvent does not have a method to obtain any remaining item from a craft. Like the empty buckets from a cake (which the Crafter ejects too btw).
Is this intentional? Technical limitation? Just an oversight? If intentional, what's the intended way of detecting any remaining items from a Crafter craft?

thorn isle
#

i'm not sure where that might be available on spigot, in nms it's Item::getCraftingRemainder, paper exposes it through the experimental ItemType class

eternal night
#

the recipe has remaining items

#

it would have to be exposed on the event

dense falcon
#

Bungee Class: https://hastebin.com/share/yofitehojo.java
LobbyCommand: https://hastebin.com/share/cocadufeyo.java

I would like that when I do /lobby it connects me to the first lobby server that has less than 20 players which is the maximum number of players on these servers, except that it connects me to all the servers that have less than 20 players, I have two lobby servers for testing and it connects me to the first, then to the second, except that I would like it to connect me only to the first one that finds, and not to the following ones, because if I have 50 servers it will connect to 50... and besides sometimes it refuses the connection, it times me out.

eternal oxide
#

Break out of the for loop if the count is less thn 20 in sendPlayerToAvailableLobby

dense falcon
#

But how I know back that's the count is less than 20?

eternal oxide
#

ah I see

dense falcon
#

I mean, I ask the info but get the result in another class, and now how I get back to my command class the result.

eternal oxide
#

where are you doing the actual connect?

#

ok its in teh bungee class

dense falcon
#

Yeah.

eternal oxide
#

because you are requesting ALL server counts you keep triggering the onPluginMessageReceived even after you found a free server

dense falcon
#

So what can I do to stop requests when the player can be tped?

eternal oxide
#

do a single request and process it on bungee

#

you can query player counts on bungee

dense falcon
#

Uh how?

eternal oxide
#

or

#

delete all your bungee listener and process it when the response is returned to Spigot

#

teh Player count is a built in bungee response

#

basically you can;t fire/forget your player count

#

well you could query ALL servers

#

that way you are not sending multiple queries

quartz sorrel

So at most could I probs get the Crafter Block and go through its slots, checking if any item returns a remaining item.... fun

hey,
i am currently trying to make a ability wich spawns multiple lines in front of the player like this example -> https://imgur.com/a/HXgb1kK not sure if i am allowed to paste those links but i think imgur.com should be safe
it should spawn always in the direction of the player and at the height of the crosshair but i cannot figure a way out how to make this properly
not very good at vector and location stuff but i tried it over the past days and i couldn't get it to work so here i am

thanks for any help its much appreciated

warm mica
#

That's your start point. Then have a simple for loop that adds a constant value to both x and z values, and draw a particle

#

For constant height, set the y of the direction vector 0 (or something) and call #normalize() afterwards. Do that before multplying the vector

eternal oxide

Guys i want to load a lot of heads into an inventory, like this, but the server lags when opening the menu, for obvious reasons, is there any way to optimize it? I can't think of anything

don't block the main thread for profile lookups

i feel like it might still be doing them

alternatively getYaw and use that

#

i don't think getOfflinePlayer loads anything

manic delta
#

any ideas how I can do this in an optimized way?

blazing ocean
thorn isle
#

iirc it's when you call on properties of the offlineplayer, like name, that loading happens from the usercache or wherever

manic delta
thorn isle
#

the texture/profile lookups

#

createprofile just creates a blank profile with uuid and possible name

#

its properties like name and skin then possibly need to be looked up from mojang/disk

blazing ocean
#

also #setPlayerProfile is paper API so yeah

manic delta
#

yea using paper

blazing ocean
#

?whereami

Hi rad

yeah spigot is super passive aggressive because of its shrinking (single-digit) market share so if they smell paper on your person they tell you to go ask them

what confuses me is why paper people even come here in the first place

undone axleBOT
#

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

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

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

Alternatively, and preferably, make use of PlayerInteractEvent#getItem() or #getMaterial() and compare against that so you could support off hand clicking of the item too

#

While the hand check is useful, it also unnecessarily blocks functionality from the off hand, which might actually be useful

slender elbow
#

that bot message really needs a facelift

worldly ingot
#

It kinda does, yeah

#

Also, smh, public event handles

How does spigot handle circular dependency?

#

like in which order are the dependencies loaded if two different plugins want different orders

long ocean
#

Why was the event.getSpawnReason() in CreatureSpawnEvent for fish out of buckets changed to SpawnReason.DEFAULT? Is this purposeful or a glitch in the current version?

#

IMO this is bad, because now the plugin can't distinguish the difference between a natural spawning mob at night and a player action. I don't think they should all be grouped together as SpawnReason.DEFAULT.

valid burrow
jagged thicket
#

makes sense

sullen marlin
#

none of the reasons look obviously related to buckets to me, so I would love to know what it used to be. Also NATURAL and DEFAULT are two different reasons

lime pulsar
#

You know how when you type a command and it says in red your messing up? Is that possible in a plugin like with onTabComplete?

long ocean
long ocean
sullen marlin
#

Not sure I'd believe chat gpt

long ocean
#

Me either, just providing all i know.

#

But logically, i guess a fish bucket in concept is like a spawn egg from the creative menu.

sullen marlin
#

I'd be interested in knowing what it actually was, if you can show what it actually was and it's different then it's very easy to change (same with the natural spawning)

jagged thicket
#

md5 md_5

long ocean
# sullen marlin I'd be interested in knowing what it actually was, if you can show what it actua...

There is no current SpawnReason. that i can see which would fit fish from bucket. If i had to pick one that was the closest i would go with SPAWNER_EGG. And i agree that vanilla mob spawning in the wild because its dark should be NATURAL instead of the current DEFAULT. I can't show you what it used to be, as i have in my plugin the allowed methods of EGG, SPAWNER, and SPAWNER_EGG and can't remember which one of those was for fish in a bucket.

sullen marlin
#

could test an old version

long ocean
#

I don't know when it changed, might have to go really old. I just noticed today my fish weren't being spawned from a bucket so debugged the spawn reason.

jagged thicket
#

even in 1.12

#

there was no such thing

#

nvm i might be wrong sorry

sullen marlin
#

code on its face does look like it uses SpawnReason.NATURAL for spawning at night

long ocean
#

Okay, i made a mistake, testing again i see that mobs in the wild are showing SpawnReason.NATURAL.

main dew
#

I remember in 1.12.2 ocelot spawn egg sometimes spawn small ocelot from reason OCELOT_BABY

long ocean
#

But you can see, bucket fish are DEFAULT

lime pulsar
#

so default means by a standard game mechanic other than natural?

#

whats it say when you bread 2 animals?

#

err breed

long ocean
sullen marlin
long ocean
#

I dont have an old version, i just run buildtools all the time. Is there somewhere to download old jars? Or do i set something in buildtools to make it do an old version? And what version should i try? And what about client? How far back will MS let you roll back your client version to connect to an old server version?

sullen marlin
#

Forever

#

--rev (version)

#

Maybe try 1.19 or something to start? Whenever you think it was different

#

wait lemme try

im gonna try 1.16

Here it is spawner egg in 1.16

# jagged thicket from blockstate?

#

Inventory is part of the block state

lime pulsar
#

in = block.getState().getInventory()

chrome beacon
#

Do note that it (get state) returns a copy

#

And therefor needs to be manually updated
EDIT: turns out getInventory doesn't require this if the state belongs to a valid block. It's only required for getSnapshotInventory

slim wigeon
#

Wait, that is not working either. What in the f***?!

lime pulsar
#

show the line as you have it now?

chrome beacon
#

Did you do what I told you to

slim wigeon
#

This is the lineInventory inv = ((Container) block.getState()).getInventory();

lime pulsar
#

Inventory inv = this.block.getState().getInventory();

chrome beacon
#

That won't work

lime pulsar
#

what class is block?

slim wigeon
#

Its just the block in the world as shownthis.block.getRelative(0, -2, 0).getRelative(0, -(this.mineTrailPlaced-1), 0).equals(Material.BEDROCK)So if its suppose to work like you saying, there is no reason that the IDE should be throwing errors but it is

warm mica
#

== is fine for enums

slim wigeon
warm mica
warm mica
lime pulsar
#

how is block defined? is it Dispenser block or Block block?

slim wigeon

Block block

warm mica
#

Alternatively you may cast it to InventoryHolder

lime pulsar
#

if(block.getType() == Material.DISPENSER) Dispenser dispenser = (Dispencer) block.getState();

blazing ocean
chrome beacon
#

Not ideal

#

getState is an expensive operation so do keep the type check

blazing ocean
#

oh right the snapshots yea

#

Yeah

#

check out this nightnmare:

#

` static Chest getChest(Sign sign) {

if (signBlock.getBlockData() instanceof WallSign) {
WallSign signData = (WallSign) signBlock.getState().getBlockData();
Block attachedTo = signBlock.getRelative(signData.getFacing().getOppositeFace());

        if (attachedTo != null && attachedTo.getType().equals(Material.CHEST)) {
            Chest chest = (Chest) attachedTo.getState();
            return chest;
        }
    }
    return null;

#

trying to help them is just useless since they ignore any kind of input

#

wow my discord really crashed after saying that

if its a dispenser from the get go why is it stored as a block?

#

Its still not working

lime pulsar
#

is inventory null?

#

or just empty?

slim wigeon
#

This is what its doing

#

This is the code where the block destroy occurs``` if( block.getType().isSolid() && !block.getType().equals(Material.BEDROCK) ) {
inv.addItem(new ItemStack(Material.STONE,1));

            block.getWorld().playEffect(block.getLocation().add(0.5, 0.5, 0.5),Effect.STEP_SOUND, block.getType());
            block.getWorld().spawnParticle(Particle.FLAME,block.getLocation().add(0.5, 0.5, 0.5), 10, 0.2, 0.2, 0.2, 0.1);
            block.setType(Material.AIR);
        }```

^^

#

I was talking about the getState being a copy operation

#

It snapshots the state

slim wigeon
chrome beacon
#

It means that the changes to the block state won't apply until you call update on it

#

since it's a copy

#

Anyways I'm not a fan of how you're keeping a reference to the Block instance

#

You're probably better of holding the Location

#

and then getting the block if you need it

sullen marlin
jagged thicket
#

thx bro!!

slim wigeon
chrome beacon
#

hm?

#

That could still be done with the Location

#

You can get the block at the location if you want to check it

slim wigeon
#

If you saying I have to change how I program, you going to be blocked. I did what you asked when it comes to the dispenser check. You got my methods

chrome beacon
#

There's no need to be offended

pliant topaz
chrome beacon
#

Yeah

#

If you don't you can keep an old outdated reference to it

#

Also if you don't clean up you can leak much more memory by mistake

blazing ocean
lime pulsar
#

what if someone uses something liek worldedit to remove the dispenser?

#

then your still chugging away with your saved block and ...

chrome beacon
lime pulsar
#

I tend to use records when dealing with blocks so the block is always coming from an event or a location

Hey guys! I am developing a plugin and I need to get materials from the player inventory.

This plugin should work on 1.8 to 1.21

My problem: If I dont set api version, it uses legacy materials. If I set api-version to 1.21, it doesnt work on 1.13, If i set api-version to 1.13, bundle stripped logs are took as normal logs.

How can I have 1.21 api-version behaviour while supporting 1.13?

#

I just want plain materials as they are

eternal night
#

you can't

#

like, the only solution would be two modules using pre/post 1.12 API

bright spire
#

Are you 100% sure? The problem is I am comparing 1.21 packets with the inventories, and if i set api-version to 1.13 the packets material's differ from the spigot's

eternal night
#

if you want to support 1.8, you need pre flattening material BS

bright spire
#

The problem is 1.21 and 1.18

eternal night
#

1.8 is fine if you set the API version

bright spire
#

Yeah the problem basically is the packet sent by player has a stripped log and if i set api version to 1.13 that stripped log in the spigot inventory is shown as normal log

eternal night
#

1.8 would not be fine if you set the api version to 1.21 and compile against 1.21 spigot

bright spire
#

No thats fine, the problem is another one

#

When comparing packet's material to server materials, if the api version is 1.13, the spigot's inventory materials differ

#

If the api version is 1.21 it works fine, but it doesnt run on 1.18

eternal night
#

so you have a plugin with api-version: 1.21
You run it on a server with spigot 1.18
And your difference is what?

bright spire
#

No bro

#

api-version 1.21 doesnt run in 1.18
api version 1.13 runs in 1.18 but stripped log is converted to normal log (this causes issues)

eternal night
#

mhm

bright spire
#

Is there a way to bypass conversion?

#

My other plan is to change api-version based on the server version... not sure if its possible

#

I think not

eternal night
#

only with a jar in jar approach

bright spire
#

Hmm

#

Is there a way to apply a conversion to a specific material?

eternal night
#

no the plugin does not have any say in the bytecode rewriting

#

could look into something like xmaterials

bright spire
eternal night
#

Material#valueOf iirc is rewritten too?
Tho only for pre 1.13 plugins

bright spire
#

I have to test

#

but i think not thx

#

are you sure there is no way to completely disable this api version behaviour?

eternal night
#

logic for that certainly exists

bright spire
#

i dont use materials at all, i just compare ones sent and received by clients

#

so they are fine, and do not need any touching

#

but spigot touches them for some reason

I am honestly surprised it even explodes then when you specifc 1.13 as an API version

bright spire
#

stripped log is changed to normal log

eternal night
#

Well yea, thats what I meant with explosion kekwhyper

bright spire
#

ah okay

#

yeah I am basically making an antiexploit feature that compares materials sent by clients and the ones actually in the server

#

so you cannot just send any item

#

but the ones whitelisted

#

problem is when api-version is specificed to 1.13, they get converted and differ, causing a client kick

lime pulsar
#

so bots like ServerOverflow can't place bedrock everywhere?

eternal night
#

How are you getting the material

#

like, converting internals Item type to Material

bright spire
#

I think this was the culprit...

#

Using toString instead of name... gets the non-converted value, and using name to compare, gives a converted value

#

I will use toString always

eternal night
lime pulsar
#

1.13 is when they stopped using numeric IDs and started using names

#

you had to add --forceUpgrade to your startup flags so you could use an existing world

Hi guys, im trying to make an rpg game (Economy oriented) so I need to create a mining system.

The way I would like it is like on Hypixel Skyblock.

The animation should match the current phase and it should be compatible with a Mining Speed stat (a double) from my PlayerManager

If anyone could help me I would highly appreciate it.

young knoll
#

You have to redo mining server side

#

Or make use of the new mining speed attribute

finite path
#

Im on 1.18.2 so I dont think that attribute is an option for me

finite path
chrome beacon
#

Give mining fatigue to stop the clientside block break animation

#

and then send the packet for it yourself

finite path
chrome beacon
#

I forget what you need to set it to

#

Might have been a negative value

#

Mining fatigue 255 should work

finite path
#

Ahh, alright and how should I get into packets? (Possibbly trying to be using as least unnecesarry libraries as possible)

blazing ocean
#

?nms

undone axleBOT
chrome beacon
#

I do recommend PacketEvents or ProtocolLib

blazing ocean
#

#

Ohh hack, thanks guys

# blazing ocean ?nms 
public final class Packets {
    private Packets() {}

    public static void send(Player player, Packet<ClientboundPacketListener> packet) {
        var vanillaPlayer = ((CraftPlayer) player).getHandle();
        vanillaPlayer.connection.send(packet);
    }
}
young knoll
#

Yeah negative mining fatigue is the way

#

The only problem with the attribute is ideally you set it before they start breaking the block

#

Which means constant ray tracing to see what they are looking at :/

finite path
#

Meh, I dont even know what to do, how to even start it...

chrome beacon
#

Start by giving the mining fatigue to the player

#

Then detect that the player is trying to break a block

#

I don't think 1.18 has the BlockDamageEvent

young knoll
#

There’s a BlockDamageEvent for the start breaking

finite path
#

It has

chrome beacon
#

so might need packets for that

young knoll
#

Idk if BlockDamageAbortEvent is in 1.18 tho for stop breaking

finite path
#

It is

young knoll
#

Well there ya go

finite path
#

And what is the packet for the animation?

young knoll
#

Is Player#sendEffectChange in 1.18?

young knoll
chrome beacon
#

Yeah that exists in 1.18.2

#

Just checked

#

Neat might not need packets after all

young knoll
#

If you have all of those methods you won’t need any packets

#

SendEffectChange for client side mining fatigue
SendBlockDamage for damage
BlockDamageEvent for start breaking
BlockDamageAbortEvent for stop breaking

finite path
finite path
#

Thanks imma try these

chrome beacon
#

hm sendEffectChange seems to be missing

#

Also does the effect need to be on client only?

young knoll
#

It makes it easier to calculate the progress on the server

#

Since you can use getBreakSpeed

#

But otherwise no

finite path
finite path
chrome beacon
#

yeah block damage is what you're looking for

#

block change is used for fake blocks

finite path
#

And yea effect change is just missing

young knoll
#

You might not have the one that allows you to specify the entity id for the damager tho

finite path
#

And which file should I use? remapped or remappd-obf

chrome beacon
#

Use the regular one

#

Don't use the jars with an extra prefix or suffix

finite path
#

Then why are they there?

chrome beacon
#

They're used during the build step

#

Some of the tooling uses the jar during the remapping process

finite path
#

But the main jar gets out first so it couldnt use it so im confused

hushed spindle
#

why the fuck is the quantity changing

chrome beacon
#

From Javadoc

slender elbow
#

because what it couldn't add, it mutates the item to have the remaining amount

hushed spindle
#

this happens even with an empty inventory

#

both spigot and paper

lusty wolf
quaint mantle
hushed spindle
#

this game is trolling me

vast ledge
#

Maybe you have to update the itemstack in the inventory?

worldly ingot
#

I don't really understand what the problem is, but it's worth mentioning that addItem() will mutate the ItemStack you pass into it

#

If you pass in itemStack with stack size 64 but it could only fit 10 items into the inventory, that itemStack instance you passed will now have a stack size of 54

#

I wish it didn't mutate the stack but that's a whole other issue

#

If your problem is that you're expecting addItem() to keep reference to the item in the inventory and expect changes to it to automatically apply to the item stack, that won't work either. When you add an ItemStack to the inventory, what's being added is a copy of that item as an NMS ItemStack, not a Bukkit ItemStack. The only time where updating an ItemStack will reflect its changes in the inventory is if you have a CraftItemStack that is mirroring an NMS ItemStack, which usually you get from Inventory#getItem() or an event or something

I already own a server of the highest caliber specifications. Budget is not a problem for me. With all this being said, I still do not want to enjoy this journey alone.

you'd typically do that with javascript rather than java

forest hedge
silver robin
# forest hedge Execute bukkit code which is sent in a discord channel

the overcomplicated way:
fetch whatever values you need from the discord channel
and then call the hard-coded method with those values
for example you make java public void iLikeThisFunction(Player player, float a, float b, int x, ...); and then java var data = fetchDataFromChannel(); iLikeThisFunction(data.getPlayer(), data.getA(), )

# forest hedge Wdym?

i mean that it's not related to particle beams at all, it could be any other functionality....
for particle beams if you want to hide the maths then pre-calculate all coordinates and particles which should be spawned there at specific tick then just iterate through that list

talking about the author

silver robin
#

creative mode is weird

#

it allows clients to just spawn any kind of item

#

with any nbt data

#

so it's actually a desync problem

#

but the server "accepted" that item you pulled out of the inventory, if you were in survival it would disappear

#

using a specific cheat client on creative servers to spawn heads, barriers, dragon eggs and command blocks was cool back in 2015

#

or a minecart with command block which was a force OP exploit 😄

off the top of my head i could maybe name 3-4 finicky bits about the api for which you need or want to copy paste an impl from someone who's already spent 10 hours fiddling with it

one of them would be to get scoreboard sidebars updating correctly without flickering

but that isn't really the api's fault; it's a client problem

How may I remove the cd between hits like in the old pvp (in 1.8) in recent versions?

worldly ingot
#

You'll want to add an AttributeModifier either to the player or to the item they're using for the ATTACK_SPEED attribute

#

Higher the number, faster the player can attack. I believe it's full strength attacks per second or something, so if you just do an ADD_NUMBER operation with a value of like 100, it will work fine

young knoll
#

Yeah it’s attacks per second

Is there a method for a plugin to retrieve a path to itself in the filesystem?

JavaPlugin#getFile()? Is that what you're looking for?

mortal vortex

worldly ingot
#

The constructor is a bit simpler now. Should be able to use (NamespacedKey, double, Operation, EquipmentSlotGroup)

# 
new AttributeModifier(
    new NamespacedKey(pluginInstance, "attack_speed_1_8"),
    4.0, // Might want to make this a bit higher. Up to you though
    AttributeModifier.Operation.ADD_NUMBER,
    EquipmentSlotGroup.ANY
);
worldly ingot
#

Can use toPath() if you want an NIO path

'getFile()' has protected access in 'org. bukkit. plugin. java. JavaPlugin'

worldly ingot
#

Mhmm. It's protected :p

mortal vortex
#

Reflection time?

worldly ingot
#

You can only use it from within JavaPlugin. If you want to use it externally, I guess a hacky workaround would be to make your own method in your plugin class called something like getPluginFile() and just return getFile() lol

No no, just a wrapper method

I'm confused.

ivory sleet
#

abbev is it ur own JavaPlugin subclass?

mortal vortex
#

All I'm doing is this right now:

private String generatePluginHash(JavaPlugin plugin) {
        try {
            File pluginFile = plugin.getFile();
            if (pluginFile == null || !pluginFile.exists()) {
                return "UNKNOWN";
            }

            MessageDigest digest = MessageDigest.getInstance("SHA-256");
            try (FileInputStream fis = new FileInputStream(pluginFile)) {
                byte[] buffer = new byte[8192];
                int bytesRead;
                while ((bytesRead = fis.read(buffer)) != -1) {
                    digest.update(buffer, 0, bytesRead);
                }
            }

            byte[] hashBytes = digest.digest();
            StringBuilder hexString = new StringBuilder();
            for (byte hashByte : hashBytes) {
                hexString.append(String.format("%02x", hashByte));
            }
            return hexString.toString();
        } catch (Exception e) {
            return "ERROR";
        }
    }

Yeah it will have to be your own instance instead of just JavaPlugin

#

If you're wanting to do this generally for other plugins, then yes, you will have to use reflection

mortal vortex
#

In my plugin, I have:

this.plugin = plugin;
``` in the constructor already.

Yeah, note I'm defining it as MyPlugin though instead of JavaPlugin

Likely using the wrong ChatColor. You want the one from net.md_5.bungee.api

#

Or whatever the package is :p

mortal vortex
#

"or whatever"?? chud. do you not respect the work of our good lord md5?

small kestrel
#

im very new to coding so i wont understand much

worldly ingot

Are you using any other ChatColors in that class?

#

Like ChatColor.RED, etc.?

#

yes

can i just use &4 or some other formatting code from minecraft

ivory sleet
#

im pretty sure if u have a non-final protected (maybe pack priv also) method, subclassing will allow u to override and open access

worldly ingot
#

The #of() method in the bungee package is for RGB colours

mortal vortex
#

I dont like the name translateAlternateColorCodes.

#

I just have a method called "bob" which is a wrapper for translateAlternateColorCodes. Bob is more pleasant.

this goes back to the whole "the programmer is supposed to put the things together" thing; what you have here is a cube and a circular hole, and you need to do something with the cube to make it fit

Hey does anyone know how I might be able to go about building my own world generator that just makes changes to the world generation that is already made? I've been looking at the ChunkGenerator and BlockPopulator classes; I may be wrong, but it looks like BlockPopulator only works with blocks added in after chunk generation, and any overrided ChunkGenerator seems to default to a void generator, and so I am unable to work with the default generation using it as I know how to. Anyone have any advice?

sullen marlin
#

But otherwise a populator should be fine, not sure what the concern you have is

Hey guys, I wanna create a detection system to detect if you're inside a certain zone or not, but these zones will be very small as its for detecting if you're on top of very small structures generally, is there anything you think i could look into to help with this implementation? It needs to be a bit optimized since there can be a lot of these in the world at once

mortal vortex
#

And maybe define your small zones as axis-aligned bounding boxes

Hello someone has alreeady done custom world generation and know how to handle biome transition regarding noise values (e.g terrain height) ?
I'm using LERP with smoothstep for the step of the lerp, for the X and Z axis on biome edges with a blendfactor of 10 and then I average them but I have an artefact problem where I have werid spikes comming out

mortal vortex
old stone
#

perhaps I can do it another way ?

mortal vortex
#

No, thats the right way. sometimes people do it incorrectly.

#

What operations are you already doing?

old stone
# mortal vortex What operations are you already doing?

Basically, I have a loop that checks 10 blocks ahead if there is a biome change, if it finds one it uses smoothstep & LERP to redefine the height if the noise at this location, and then breaks the cycle. Since the generateNoise function is called for each block. It works well with only X, when I put Z, I have as I said artifacts

#

I've also try weighted average like so

        for (int i = 0; i < k ; i++) {
            Biome biX = baseBiomeProvider.getBiome(worldInfo, worldX + i, worldInfo.getMaxHeight() / 2, worldZ);
            Biome biZ = baseBiomeProvider.getBiome(worldInfo, worldX, worldInfo.getMaxHeight() / 2, worldZ + i);

            if(biX != currentBiome || biZ != currentBiome) {
                float t = WorldUtil.smoothstep(0.0f, 1.0f, (float) i / (float) k);

                int caveTopX = biomeServiceFactory.getBiomeService(biX).getCaveTop(worldX, worldZ);
                int caveTopZ = biomeServiceFactory.getBiomeService(biZ).getCaveTop(worldX, worldZ);

                double smoothCaveTopX = WorldUtil.lerp(caveTopX, caveTop, t);
                double smoothCaveTopZ = WorldUtil.lerp(caveTopZ, caveTop, t);

                double deltaX = Math.abs(caveTopX - caveTop);
                double deltaZ = Math.abs(caveTopZ - caveTop);

                double totalDifference = deltaX + deltaZ;
                double weightX = totalDifference > 0 ? deltaX / totalDifference : 0.5f;
                double weightZ = 1.0f - weightX;

                caveTop = (int) (smoothCaveTopX * weightX + smoothCaveTopZ * weightZ);

                break;
            }
        }

But it doesn't work quite well, I still have artifacts

#

and with the normal arithmetic average I have

mortal vortex
#

do you also notice like incosistent blending when it comes to diagonals?

old stone
# 
        for (int i = 0; i < k ; i++) {
            Biome biX = baseBiomeProvider.getBiome(worldInfo, worldX + i, worldInfo.getMaxHeight() / 2, worldZ);
            Biome biZ = baseBiomeProvider.getBiome(worldInfo, worldX, worldInfo.getMaxHeight() / 2, worldZ + i);

            if(biX != currentBiome || biZ != currentBiome) {
                float t = WorldUtil.smoothstep(0.0f, 1.0f, (float) i / (float) k);

                int caveTopX = biomeServiceFactory.getBiomeService(biX).getCaveTop(worldX, worldZ);
                int caveTopZ = biomeServiceFactory.getBiomeService(biZ).getCaveTop(worldX, worldZ);

                double smoothCaveTopX = WorldUtil.lerp(caveTopX, caveTop, t);
                double smoothCaveTopZ = WorldUtil.lerp(caveTopZ, caveTop, t);


                caveTop = (int) (smoothCaveTopX + smoothCaveTopZ) / 2;

                break;
            }
        }
mortal vortex
#

Have you tried a cubic or quintic interpolation?

old stone
#

i'm gonna show you

old stone
#

Because I have the feeling that the problem here comes from the way smoothCaveTopX and Z are handled together

mortal vortex
#

Weighting should have worked.

old stone
#

I'll send you images in DM because I cannot send here

#

note that k = 10

#

and int caveTop = biomeService.getCaveTop(worldX, worldZ);

#

with BiomeService biomeService = biomeServiceFactory.getBiomeService(currentBiome);

#

just gives me basic settings for each biomes, (here just a number which is the caveTop)

according to the wiki beacons only care about horizontal distance, limited by simulation distance
according to mojanks code as in spigot, this doesnt work downwards

i do not have the beacon effect if im below it

thats just how vanilla works, no?

isnt it supposed to give the effect down too?

nova notch
#

im pretty sure i researched it and it looked like it doesnt cus i was gonna put a beacon above my base and realized it wouldnt work

#

let me double check

#

oh ok i was partially right

#

so it actually goes infinitely upward but only like 20 blocks below

smoky oak
#

thats such nonsense bruh

nova notch
#

yeah it honestly makes no fucking sense but it is what it is

can you turn the beacon beam invisible

probably with a texture pack

#

or just like manually apply the effect

You shouldn't be mixing legacy colour codes with components. You're at least using fromLegacy() but still not ideal. Something like this would work

BaseComponent message = new ComponentBuilder("")
    .append(new ComponentBuilder("[Accept]")
        .event(new ClickEvent(ClickEvent.Action.RUN_COMMAND, "/duel accept " + from.getName()))
        .event(new HoverEvent(HoverEvent.Action.SHOW_TEXT, new Text("/duel accept " + from.getName())))
        .color(net.md_5.bungee.api.ChatColor.GREEN)
        .bold(true)
        .build()
    )
    .append(" ")
    .append(new ComponentBuilder("[Reject]")
        .event(new ClickEvent(ClickEvent.Action.RUN_COMMAND, "/duel reject " + from.getName()))
        .event(new HoverEvent(HoverEvent.Action.SHOW_TEXT, new Text("/duel reject " + from.getName())))
        .color(net.md_5.bungee.api.ChatColor.RED)
        .bold(true)
        .build()
    )
    .build();
to.spigot().sendMessage(message);
#

I also don't remember if the run command action requires a forward slash or not in its value. I don't think it does but I could be wrong

#

(the ISException is possibly the use of the deprecated HoverEvent constructor, note I used Text instead of passing in a component)

Since they are being run from chat, commands must be prefixed with the usual "/" slash, and player must have the required permissions. In signs, the command is run by the server at the sign's location, with the player who used the sign as the command executor (that is, the entity selected by @s).

You could pull a StableDiffusion model straight from HuggingFace. No need to distribute it with your plugin.

#

How are you planning on loading the model?

#

I honestly think it might be better to simply define a standardized endpoint in your config. The user then has to select if he wants to start a model locally in api mode, or if he simply
pays for an online service. There are two standard api implementations for rest endpoints afaik.

#

But maybe you can find a Quantized StableDiffusion 1.5 Model that is around a GB

grim hound
grim hound
#

How much memory does it consume?

lost matrix
#

Inference will always consume a couple of GBs. And generating an image on your CPU will also take several minutes.

#

Ive seen it run on a raspberry pi, consuming around 6GB of ram for a single generation.

#

This is probably the lowest you can get with the base model:

from diffusers import StableDiffusionPipeline
from PIL import Image

pipe = StableDiffusionPipeline.from_pretrained("../stable-diffusion-v1-5", low_cpu_mem_usage=True)
pipe = pipe.to("cpu")

prompt = "a black tree with golden leaves painted by Monet, autumn"
image = pipe(prompt, num_inference_steps=30, width=512, height=512).images[0]

image.save("output.png")

Requires the user to have Pyhton, Diffusers and Torch installed.

#

Honestly, you can probably quantize an SD 1.5 model. But this requires quite a bit of tinkering and knowledge about quantization.

thorn isle
# grim hound How much memory does it consume?

depends a bit but typically the size of the model itself, could be a little bit less because there's metadata in the file and could be a bit more if the weights don't align with native data structures

#

because at the end of the day inference is just crunching the weight numbers with a smaller set of transient numbers

#

if you have 250mb of weights, then it'll use 250mb of memory

#

all that said huggingface also offers free-to-use endpoints so it probably doesn't make much sense to bundle it into your plugin

blazing ocean
thorn isle
#

just call their api (and probably let the user specify an api token in case they want to get the paid-for rate limits) and use that

blazing ocean
#

or just use the openai api

#

or just don't use ai

thorn isle
#

that costs money

blazing ocean
#

right, models aren't free to train and run either

thorn isle
#

huggingface requires an account and an api token, but usage is free

#

of course you're competing with 5 billion other free users so it can be quite slow

#

and if you use some fringe model nobody else uses it'll take like a minute for it to get loaded from the void realm

blazing ocean
#

i love having 5 billion api consumers
