[quaint mantle]

rearrange code i think actually

something like that

I recommend to read a book called “clean code”

[onyx fjord]

?

[quaint mantle]

just learn how to format it properly and then you don't have to use something to do it for you

¯_(ツ)_/¯

?

[onyx fjord]

if you have non standard formatting add .vscode folder and put your formatter changes in the settings there

[quaint mantle]

You can also use eslint and prettier for that

[sturdy reef]

stop dirt turning to grass?

@EventHandler
    public void onBlockChange(BlockPhysicsEvent event){
        if(event.getSourceBlock().getType()==Material.DIRT&&event.getChangedType()==Material.GRASS_BLOCK)
            event.setCancelled(true);
    }```

tried this and it didn't help

[idle sparrow]

event.getSourceBlock().getType()==Material.DIRT&&event.getChangedType()==Material.GRASS_BLOCK that formmating is wild

[placid moss]

are you sure blockphysics event is trggered

[smoky anchor]

what formatting, you see any formatting ?

[idle sparrow]

zero spaces lol

[smoky anchor]

exactly

[idle sparrow]

y muh code not wurk bruh

[smoky anchor]

Are you registering the event ?

[sturdy reef]

ye

[smoky anchor]

one thing you can do is: put debug messages with the sourceBlock.type and changedType and go to an empty world to try and see what it prints

[shadow night]

is there an event for when a player has a new item in his inventory? Like, in any way, taken from a chest, picked up, crafted, given through commands, etc.

[eternal oxide]

no

[shadow night]

so, I will have to listen to all kind of events where the player can get an item through?

please tell me somebody has a library that does that

[vivid cave]

when does PrepareAnvilResult trigger ?
does it trigger following a client request to server ?
or does server find out by itself that the inventory has changed in the anvil ? and therefore prepare a new result
(i need a specific answer)

[vivid cave]

tbh, it's not THAT much.
How can a player get an item ?

• EntityPickupItemEvent
• InventoryClickEvent (transfering stuff from an inventory to another)
• commands / plugin interferance

Can't think of anything else

[shadow night]

Hmm

Either I listen to event or I check every tick for inventory changes

[vivid cave]

it depends on what tracking level you want to be honest
If you agree to occasional misses/untracked items (for whatever reasons, like commands/plugin interferance), then prolly listen to events
Otherwise if it's of UPMOST importance that you don't miss a single one, go with the task ticking at every tick thinggie.
If you're going to do the task, I would advise to do it ASYNC.

[lament plank]

How do i launch a player Forward

Because it just keeps highlighting .setVelocity on red

[eternal oxide]

what are you passing to setVelocity?

[eternal oxide]

setVelocity takes a vector

[lament plank]

vector is in red as well

[eternal oxide]

?nocode

[undone axle]

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

[eternal oxide]

V not v on Vector

[lament plank]

the set velocity is till red

[eternal oxide]

Seriously?

[lament plank]

yh

[lament plank]

woops

forgor

ty for pointing it out

ty for help

[shadow night]

Why

[shadow night]

I need to add the player into a list while they have that item and remove them once they don't anymore

[vast ledge]

use an if statment

n inventory change or smth

on*

[shadow night]

yeah that's understandable but there is no event that is fired on any change of inventory, I need to listen to like 3 events

[vast ledge]

yea and?

the listen to 3 events

then*

[shadow night]

I will

[vast ledge]

ok

[shadow night]

I know how to do it, just that 3 events seems a lil too much

[vast ledge]

is there not an inventory change event?

[shadow night]

Seems like not

[spare hazel]

how to get the player location as a block location?

[vast ledge]

player get location. getblo k

[shadow night]

InventoryAction is not an event

[spare hazel]

okay thanks

[vast ledge]

it's an enum, look to what Event it belongs

[sterile breach]

HI, its possible to set the tab completion for command of another plugin?

[shadow night]

Hmm, I think it is, but I don't know how

[hazy parrot]

Get it's JavaPlugin instance, getCommand and setTabCompleter on it

[young knoll]

There’s only 2 inventory events

Click and drag

[eternal oxide]

inventory can also change when interacting with armor stands

[shadow night]

So, player interact event?

[young knoll]

Oh are we talking any change?

Have fun then

[vivid cave]

No

[shadow night]

Maybe I should just t i c k

[young knoll]

PlayerInteractEntity

PlayerPickupItemEvent

[eternal oxide]

can't detect dropping items with Q either

[shadow night]

I'm just checking every tick, okay?

[eternal oxide]

I'd check slower

[shadow night]

Because I'm not listening twenty events

[eternal oxide]

every 5 ticks or every second

[shadow night]

That can not capture something, in theory

[eternal oxide]

you don;t need to detect a change faster than every second for your purposes

[shadow night]

Ok

[pseudo hazel]

listening to a few events is still better though

[eternal oxide]

just using events will miss changes

[pseudo hazel]

like what ones

[eternal oxide]

pressing Q

[pseudo hazel]

I mean maybe the give command

there are events for that

[eternal oxide]

nope

not unless it was added in teh p[ast month or so

[pseudo hazel]

PlayerDropItemEvent?

I have been using it for the past few years in 1.18+

so idk when it was added

but it exists 120% sure

[eternal oxide]

I can't test at the moment, but last time I tried tracking inventories Q was completely missed

[pseudo hazel]

maybe save for the /give command spawning items in your inv you can detect any other change in the player inventory

well I am actively using it in my plugin

[young knoll]

Internally minecraft has an event for inventory change

It’s used for advancements

It’d be nice to expose it one day

[hushed spindle]

is it fine to loop through the values() of an enum in a static method within said enum called on a static variable also in said enum or will that cause some initialization error

sorta like this

or would it be better to do that elsewhere

[quaint mantle]

What theme is that

[pseudo hazel]

I think thats fine

[hushed spindle]

one that i unfortunately got used to

eclipse dark theme

[pseudo hazel]

that theme is called eclipse im pretty sure

or not?

[hushed spindle]

yeah its eclipse

[pseudo hazel]

nice, my memory does not deceive me

[hushed spindle]

i like how varied the colors are because it somehow helps with dyslexia lol

[opal juniper]

i mean it should be fine

[pseudo hazel]

I like colors too

[hushed spindle]

epic

[opal juniper]

it would be nicer if it was just like a lookup but, meh

[quaint mantle]

The colors are great

[hushed spindle]

a lot of people have been calling it an eyesore lol

which i sorta get

[quaint mantle]

I use light themes

[spare hazel]

Ur crazy

[quaint mantle]

Why

[charred blaze]

hey can anyone share correct way to add players tab completion on bungeecord commands? Im currently listening to TabCompleteEvent and returning online players names

[shadow night]

Where, how, where do I do??

[pseudo hazel]

well internally means you cant use it

only if you work at mojang

[hazy parrot]

return just player names which name startsWith with that argument

[tribal valve]

so i have this:

if (args[1] != "*") {
  sender.sendMessage(FCore.prefix + ChatColor.RED + "Player is not online");
  return true;
}
``` and when i type * it still prints that the player is not on server

[quiet ice]

Always use .equals for strings

[tribal valve]

why

[quiet ice]

Trust me bro

I ain't going to explain OOP to you

[tribal valve]

i heard that when you use .equals it checks for the memory slot if its the same and not for the string itself

[young knoll]

You’ve got that backwards

== checks memory location

[tribal valve]

ohhh

but i use == and it works

if (args.length == 1) {}
``` this works

i used equals and still doesn't work

[urban mauve]

does GenericSpeed attribute change player's speed while he jumping? like slowness potion and jumping? is it will be same or player's speed will be same like he walkin'?

[smoky anchor]

well here you're not comparing String
you will probably want to do !args[1].equals("*")
Note the negation at the start

[tribal valve]

ohh i forgot about the negation, now it works thanks

[spare hazel]

how can i create a temp Minecart and make it invincible and invisible?

[smoky anchor]

invisible possible only with a resourcepack
invincible - probably cancel event on your "custom" minecart
But.. why do you need a minecart ?

[urban mauve]

remember cords, delete it and if u need it - spawn new on this cords

[quiet ice]

Aren't minecarts entities?

[smoky anchor]

well yes

[quiet ice]

This seems really straightforward to me as you can just use the two bukkit methods for that

[upper hazel]

hi boys end gers

[quiet ice]

So ... What is the catch?

[spare hazel]

to make the player ride it and apply the velocity to the minecart to prevent the player from changing the direction and velocity

[upper hazel]

i bad speak english but i will use translate

[smoky anchor]

minecarts can not be given invisibility

[quiet ice]

That's stupid

[smoky anchor]

you can use a different entity

that can be invisible

[upper hazel]

Who knows what entity is used to create a plugin for the ball in the bukkit api?

[spare hazel]

but pigs can. great idea i will give the pig invincibility and invisibility

[smoky anchor]

usually you would use an armor stand I believe

[spare hazel]

can u ride an armor stand?

[smoky anchor]

or snowball if you need a different trajectory

[spare hazel]

but wait

[smoky anchor]

with plugins, yes

[spare hazel]

gravity affects different enitities differently

[quiet ice]

I'd use bats but it all boils down to the same thing

[upper hazel]

can i spin the snall ball if i want? I just saw that when you hit the ball, it was spinning or is it such a texture pack?

[quiet ice]

You can disable gravity to my knowledge

[spare hazel]

but then i cant move the entity bcz im adding force with velocities

[quiet ice]

Won't change anything, right?

[spare hazel]

it will

no gravity no velocity

[quiet ice]

Really?
God mc is dum

?jd-s

[undone axle]

https://hub.spigotmc.org/javadocs/spigot

[spare hazel]

lemme just check how hypixel did it

[quiet ice]

So https://hub.spigotmc.org/javadocs/spigot/org/bukkit/entity/Entity.html#setGravity(boolean) really prevents any movement?

[smoky anchor]

it does not

[spare hazel]

public static Vector getVelocity(Location start, Location end){
        double flatDistance = Math.sqrt(Math.pow(end.getX() - start.getX(), 2) + Math.pow(end.getZ() - start.getZ(), 2));
        double Y = (flatDistance * 32) / 2;
        return end.clone().toVector().subtract(start.toVector()).add(new Vector(0, Y, 0));
    }

and the calculations here are broken can anyone take a look at them? they throw the player a few blocks off

and when i say a few i mean 20 blocks

[spare hazel]

you can still move with getLocation().setZ(69); but thats laggy

[eternal oxide]

you can not throw a player beyond a certain distance. You have to do it incrementally

[urban mauve]

any solution like PlayerJumpEvent?

[spare hazel]

no it throws more than what i defined

[quiet ice]

PME velocity Y > 0 AND player touches ground

[urban mauve]

GOOD(WORKING) solution?

[smoky anchor]

player stat event > Jumps ?

[urban mauve]

i will try it, thanks!

[quiet ice]

Under what scenario does that not work?

[spare hazel]

when the player falls of an edge

[smoky anchor]

when they take damage ?

[quiet ice]

Okay yeah

[smoky anchor]

also, don't trust player.isOnGround()
Controlled by client, can be spoofed

?image

?img

[undone axle]

Not verified? Upload screenshots here: https://prnt.sc/

[quiet ice]

Yeah you'd need to get the block below the player and check the Y coord of the player feet

[sterile breach]

hello, I am trying to recover the face of a block (like south, op, down etc...) (when it is broken) how to do?

[smoky anchor]

player has base 1 damage

[spare hazel]

is there a way to change the hardness of a block withouth using protocollib and mining fatigue?

[smoky anchor]

no

[smoky anchor]

This is the third time this is being answered this month

[urban mauve]

it worked, thanks!

[smoky anchor]

Don't tag me to ask "do I know"

If I did I would answer

[shadow night]

is having a for loop in a for loop in a for loop and doing that every second gonna impact performance heavily enough to be notable?

[smoky anchor]

depends on how often you do this, how much you iterate, what you do

[shadow night]

uh

every 20 ticks, loop through all players, loop through all their inventory items and loop through a list and do stuff

[shadow night]

it does sound very bad to me

[smoky anchor]

well if you have to do this, then you can split the inventory interating for different players on different ticks

but yeah.. it does sound bad

[shadow night]

I need an event to know when the player has a new item

[eternal oxide]

no need to iterate the inventory, just use .contains

[smoky anchor]

create an advancement for every item

[smoky anchor]

guess what contains does

[eternal oxide]

yes, but he was about to get teh contents and loop every item

[urban mauve]

another problem is double jump:
it counts as 1 jump when u press two times jump button
is there any ideas?

[smoky anchor]

minecraft does not have double jumps ?

[shadow night]

wouldn't that like take an itemstack?

[eternal oxide]

yes

[shadow night]

won't work for me

[eternal oxide]

why?

[shadow night]

diamond sword with custom model data with a shit ton of stuff that I'm not checking

[urban mauve]

i mean when u press jump button once - it works, yeah
but when u press jump button two times - its not working

[smoky anchor]

cause you can't jump if you're not touching ground ?

what are you trying to do

mid-air jumps are usually checked with "player wants to fly" thingie

[urban mauve]

i wanna disallow player to jump

[shadow night]

atleast it works tho

[brave lynx]

you can add a jump boost potion effect with a level of 250 which just disables jumping on land

[shadow night]

I wonder how many players are enough to make that cause any lag

[eternal oxide]

what effects are you applying with these items

[upper hazel]

how add image here

[urban mauve]

i won't use potions

[shadow night]

it's hard to explain, basically
person wears leggings -> Everybody else#hidePlayer(..., Player wearing leggings);
person that has sword -> show that player but make them invisible and hide their armor and item in hand so that they are hitable

I think I'm gonna do it in a different way

[eternal oxide]

you could tie these to enchants

so when x enchant is applied you do your thing

[upper hazel]

<dependency>
<groupId>com.sk89q.worldguard</groupId>
<artifactId>worldguard-bukkit</artifactId>
<version>7.0.5</version>
<scope>provided</scope>
</dependency>

so many vulnerabilities

[shadow night]

if I knew how, I would, but I'm gonna do it in a different way ig

[eternal oxide]

as ItemStack enchants can be set to only activate when worn in a specific slot

[shadow night]

I have an idea how I can do it

[upper hazel]

wth maven trush?

[tender shard]

latest is 7.1.0-SNAPSHOT or 7.0.8

[remote swallow]

you can ignore most of them

[shadow night]

yep

[tender shard]

why don't you update your worldguard dependency to latest

[upper hazel]

lol but this say this very bad

i use for 1.16.5

[tender shard]

7.0.8 and 7.1.0-SNAPSHOT both work on 1.16

also you're not shading any of those dependencies so transitive vulnabirilities don't matter at all for you

[urban mauve]

i made a custom PlayerJumpEvent, it works based on statistics
when the player presses the jump button 1 time, it works, but when he presses it twice in a row, it skips the jump. any ideas about this?

[remote swallow]

because they're already in the air

[tender shard]

I use this to detect jumps
spigot: https://github.com/JEFF-Media-GbR/JeffLib/blob/master/core/src/main/java/com/jeff_media/jefflib/events/PlayerJumpEvent.java#L98
paper: https://github.com/JEFF-Media-GbR/JeffLib/blob/master/paper-hacks/src/main/java/com/jeff_media/jefflib/events/PaperPlayerJumpEventListener.java
works fine iirc

[upper hazel]

thenks warning gone

[urban mauve]

oof i will look at it thanks
i need just figure out it

[shadow night]

somebody please create an inventory change event which is fired on any change of the player inventory, because wow this is fucked up

[pseudo hazel]

cancel the player move event

will kick players when in mid air though

atleast for me it did

[upper hazel]

guys, gentlemen, I would like to ask you something. I make my "good" plugin for the hologram, but the problem is (because the hologram is an armourstand) the hologram gets stuck and shifts to the side if it is in some kind of block (I make the plugin for airdrop and the hologram shifts because of the chest)

[tribal valve]

Is there a way to connect a discord bot to Minecraft plugin? Like a verification, you need to enter a "password" that bot sent you into a Minecraft command. So bot sent u a password, and you need to enter a /verify command on Minecraft server with the password as argument, and then the bot gives you roles etc.

[upper hazel]

i think you can but dont know how

[shadow night]

sounds like something you'd need the JDA for

[tribal valve]

Make armor stand no gravity

[tribal valve]

I thought of storing the password inside bot database and checking with the plugin for the password in the passwords database

[quaint mantle]

bro what the hell

[shadow night]

I had the same issue

[quaint mantle]

how did u fix it

[shadow night]

apparently it was the mc dev plugin

[upper hazel]

i try this not help

[shadow night]

or addon

whatever you call it

[quaint mantle]

dont i need that tho? or am i crazy

[shadow night]

you can work without it

[tribal valve]

Crazy? I was crazy once

[quaint mantle]

no

[tribal valve]

They locked me in a room, a rubber room, a rubber room with rats, and rats make me crazy.

[shadow night]

well, this is not the channel to be discussing that

[tribal valve]

Okay sr

[remote swallow]

Crazy? i was crazy once. They locked me in a room. A rubber room. A rubber room with rats. and rats make me crazy.

[quaint mantle]

Crazy? i was crazy once. They locked me in a room. A rubber room. A rubber room with rats. and rats make me crazy.

[stray trench]

can someone help me i am trying to add 3 absoption hearts to an player but i can find any information online on how to do it

[upper hazel]

the entity is moving anyway

[quaint mantle]

what event do i use to prevent this from happening?

[upper hazel]

wth how you add vidio ii not can

[quaint mantle]

verified

[upper hazel]

oh good

[brave lynx]

Hey, does anyone have any ways I can disable moving completely? I have managed to disable jumping & moving on land but if the place is in water or is submerged, the player moves freely

[upper hazel]

???

[quaint mantle]

what ???

i dont want you to be able to take out the items

from the other inventory

but u still can with double clicking the item on your own inventory

[upper hazel]

what this do

ah i see

[quaint mantle]

|| event.getClick() == ClickType.DOUBLE_CLICK || event.isShiftClick() i think this should help

[shadow night]

incase of event.getAction() == InventoryAction.COLLECT_TO_CURSOR, how do I know what slot it has been taken away?

[quaint mantle]

thanks i wanted that

[shadow night]

lol

I answered somebodies question with my question

[quaint mantle]

nvm it didnt work

[shadow night]

wait, can you collect a stack?

[timid hedge]

How do i make so if you write "test" on the first line of the a sign all the lines will be set to example "123"?

[tender shard]

ugh how am I uspposed to add the BSD license to my pom.xml and where do I even find the original text of it o0

[worldly ingot]

Depends on which one you want. There are multiple BSD licenses

https://en.wikipedia.org/wiki/BSD_licenses

[tender shard]

the one buildtools uses

bsd clause 3 IIRC

[worldly ingot]

Yeah, that's in that wiki page there

Verbatim text you can copy/paste and replace placeholders

[tender shard]

?paste

[undone axle]

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

[tender shard]

error when running mvn license:update-file-header -> https://paste.md-5.net/epowijamot.sql
pom: https://paste.md-5.net/capijulofe.xml

i alöso don't really understand how someone is supposed to know that buildtools is BSD 3 when it's nowhere mentioned

[timid hedge]

?

[tender shard]

there also doesn't seem to be any official link to the bsd 3 license, at least I couldn't find any

[stray trench]

does anyone know how to set absorption hearts in 1.8

[tender shard]

guess I'll just go back to GPL3, at least they mention in their license text that it's GPL 3, unlike BSD3 which just mentions some things but doesn't even give its own license a name

[shadow night]

what inventory action could be when a player picks up an item in any way?

if the player shift clicks, what action is it?

[worldly ingot]

Well the idea is that the actions are all distinct lol

So you'll have to account for multiple actions

Or rather, probably more appropriately, you can check whether the current item is null and the clicked item is not (the first condition being optional if you want to include swaps)

[pseudo hazel]

shift click is inventory click event

pick up from the ground is entityPickupItemEvent or something

[shadow night]

Yeah something like that

I just have a shit ton of events rn just for simple shit

[cinder abyss]

Hello, my armor stand I don't have the text of the armor stand displayed, how can I fix this ?java ArmorStand stand = Objects.requireNonNull(location.getWorld()).spawn(location, ArmorStand.class); stand.setInvisible(true); stand.setInvulnerable(true); stand.setGravity(false); stand.setMarker(true); stand.setCustomNameVisible(true); stand.setCustomName(text);

I made an instance in my main class, yet its still showing an error. However, this error doesnt appear when I use a command to spawn it.

Only when triggered by an event

I assume it has something to do with the instance, Ill try moving it into the main class

}.runTaskTimer(plugin,500L,100L);

it has something to do with the instance

I dont get the error when I call the event in the main class

[river oracle]

stop abusing static

just pass a reference into the constructor

[tender shard]

Then „plugin“ is null

[upbeat fog]

Yeah It worked, I dont get the error anymore. Thank you

I just used Main.getInstance()

owo when was this added or has it always been a thing and I've never seen it because I don't ever have a use for spawning an entity

How can I detect a player attempting to break or take out the item from an item frame that is set as fixed? (You cant break fixed itemframes / take items out of them, and it doesnt trigger the EntityDamageEntity event when hit)

why in realmines it says you could write placeholder "%realmines_secondsleft_MINE%" and it doesn't work

Hi,
I'm trying to modify a Block Display Entity to make its size or block displayed change. but I don't know how to do it. Can somebody help me ?

[tribal valve]

@EventHandler

        if (e.getEntity() instanceof Player) {
            Player player = (Player) e.getEntity();
            //may add only add if damager is a player too (later/vote)
            this.cooldown.put(player.getUniqueId(), System.currentTimeMillis());
            Bukkit.getScheduler().runTask(FCore.GetInstance(), new Runnable() {

``` how i can stop the task on some other event??

[autumn cave]

Hey, so Sign block state now has two sides (FRONT and BACK), so getLines() is deprecated in favor of getSide(...).getLines(). But Player::sendSignChange still sends only lines, not sides. Is this because lines should be in a certain order? Or its because it was forgotten in the update or is there now another way to send Sign Change update packet to the player? Thx

[urban mauve]

put this task on hashmap and then get it and cancel

u ask me as if I have done anything with packets

[green prism]

How can I spy which Plugin is changing my GENERIC_MAX_HEALTH Attribute?

(On join)

[young knoll]

You aren't the packet god?

[restive mango]

It's not entity_action, not use_item, not client_command, not window_clickk, not use_entity, not struct, not close_window

[young knoll]

It's Player Command on wiki.vg

[restive mango]

that's not an option for me...

@young knoll

[young knoll]

5.0 of what

[restive mango]

com.comphenix.protocol

[young knoll]

Okay so protocollib

Idk what their name for it is

[restive mango]

maybe CLIENT_COMMAND

i'll try that

wait

i already tried it

FUCK

[quaint mantle]

i have a client side block and I cancel the event for when they do it

Is there a packet I need to send back to the client because when they break it, it disappears

            Bukkit.broadcastMessage("Received a packet digging.")

            // TODO: we may need to send a block Ack packet (Agnowledge)
            if (BlockTracker.isPacketBlock((event.player as Player).uniqueId, wrappedPacket.blockPosition, (event.player as Player).world.name)) {

I am creating a custom creature using a resource pack and display entities. I need to give it a pathfinding algorithm. Should I run the pathfinder asynchronously?

[young knoll]

But it's not easy

https://github.com/patheloper/pathetic it is with pathetic

[remote swallow]

coll is pathetic

[hybrid spoke]

i dont doubt that

[zenith gate]

how can I set a bee's flying speed? setting the attribute flying speed does nothing, should I use vectors instead?

[quaint mantle]

https://streamable.com/j7b50q

This is what happens

[young knoll]

Why do you need to listen to packets for this anyway

[opaque scarab]

If I did do the heavy weight piece of the algorithm async, I was thinking of having a synchronous runnable check the locations of blocks and store it, then have the async algorithm review the stored blocks and their locations, then pathfind around them. Does this seem like a good idea to keep things less intensive on the server?

[hybrid spoke]

you really dont want to dive into that pool

also to switch to sync, then fetch the blocks and locations aka. the chunksnapshot, on which you can operate async btw, then go back to async to use that information is inefficient as hell

[hybrid spoke]

take a look at this. exactly what you need and if you still want to do it yourself, we did all of this already, you could take inspiration of it

[opaque scarab]

So I should just pathfind entirely sync? Should I have the pathfinder run every tick, or have it run periodically, updating the path every few ticks?

[hybrid spoke]

what? no

[opaque scarab]

Then what seems like a good solution to minimize lag?

[hybrid spoke]

to do it right and async lol

[opaque scarab]

You just said going back in forward between async and non-async is isn’t efficient LOL

[hybrid spoke]

because it isnt

[opaque scarab]

But it’s still the best solution?

[hybrid spoke]

never said that

[hybrid spoke]

once again, you could take a look at pathetic, the currently best open source spigot pathfinder lib, which already did what you want

especially at our snapshotmanagers which do the magic to go fully async

Is it possible to set a block in your inventory to be completely unplacable?

I know you can use the PlayerInteractEvent and cancel the event but is it possible to just remove the ability of getting that little animation before the block gets removed in full?

[opaque scarab]

If I was to pathfind async, won’t I need to check the surroundings sync?

[fluid river]

isn't blockplace stoppin your hand from moving

[hybrid spoke]

?learntoread should be a command at this point

[fluid river]

hehe

[hybrid spoke]

nah it still "places" the block but it instantly vanishes

[fluid river]

you can try PlayerAnimationEvent tho

[quaint mantle]

will look into it

[hybrid spoke]

could be a packets thing

[fluid river]

maybe you can cancel it from anim event

[quaint mantle]

would BlockPlaceEvent stop the animation

[hybrid spoke]

https://tryitands.ee/

[fluid river]

you need to catch both

[fresh timber]

Is there an event for when a player's main hand item changes. Not like JUST when they swap with offhand but ANY time that the main hand of the player changes to a different item?

[fluid river]

try looking through javadocs

i don't remember event like this

[dull goblet]

you probably will have to check it yourself, i think that's too specific

[zenith gate]

if there isnt one. its not hard to get around it. you could just run a runnable and constantly check through all online players inventoriies and handle what you want that way.

[quaint mantle]

Can I update to jdk +16 using spigot 1.8?

[remote swallow]

1.8 has to use java 8

[opaque scarab]

Player PlayerItemHeldEvent triggers when a player holds a new item. If it does trigger when the player holds a new item in the offhand, do event#getNewSlot If the slot int isn’t the offhand slot, it’s the main hand

[quaint mantle]

i wanted to use patters on instanceof

[remote swallow]

cast it

[river oracle]

then don't use 1..8

[quaint mantle]

already done xd

[quaint mantle]

I need 1.8

[remote swallow]

if (something instanceof somethingelse) {
    somethingelse else = (somethingelse) something

[quaint mantle]

so I just cast and done

[quaint mantle]

ye ye I know

[river oracle]

I forget how taskTimer always works. does delay mean it delays the timer for x amount of ticks every x period

[remote swallow]

delay is before it runs, period is how long between runs

[river oracle]

ok

so setting delay at 0L is just fine

since I don't really need a inital delay

[restive mango]

/lay plugin

I would like to listen to that packet so when a player is /lay ing

They can click the leave bed button

And actually stand up

Rn they just have to use the command again

[remote swallow]

look at how gsit does it

[river oracle]

so this code would just run the task every tick right?
task.runTaskTimer(plugin, 1L, 1L);

[remote swallow]

yeah

[river oracle]

ugh the wording in the docs always confuse the shit out of me

[remote swallow]

im pretty sure they make you ride something so you press shift to get out

?paste

[undone axle]

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

[fresh timber]

those methods dont fire at all

[quaint mantle]

if anyone has an idea for this please lmk. BlockBreakEvent also and it gives the same effect as cancelling the PlayerInteractEvent

[fresh timber]

paste is bad

[hybrid spoke]

you are

[fresh timber]

nah

[hybrid spoke]

probably not possible

[fresh timber]

yea

i think the tick that the block is there has to happen

[opaque scarab]

It shouldn’t be static I don’t think

[fresh timber]

yea thats what they all say

[remote swallow]

use naming conventions

[fresh timber]

so event shouldnt

oh yea ur right

[hardy minnow]

I fixed it btw

[fresh timber]

its a static event

which normally works

fine

idk why i did that tho

[remote swallow]

u aboos static

what did static do to you

[amber vale]

What event gets called when an item frame breaks from being inside a block?

[opaque scarab]

What do you mean by inside a block?

[pseudo hazel]

you can place a block against a blockface that has an itemframe

then the itemframe will break

[opaque scarab]

Huh, didn’t know that

[amber vale]

Yeah

The only way to cancel that I have found is to make it unbreakable by players in survival, which makes it so I can't get an EntityDamageEntity of it when a player hits it to do the functionality I want to, so that isn't really an option.

[opaque scarab]

This is just a guess, but since item frames are entities, you can do EntityDeathEvent. If the entity is an item frame, check the coordinates of the entity’s death. Get the material of the block at those coordinates, and if it isn’t air, trigger whatever you want

[river oracle]

Is there any way when translation back to the chunk I can get the opposite edge I'm getting right now? basically I'm getting these to points, but I really want the ones on the opposite side of the chunk

[fluid river]

catch Event and print which event class got fired

[echo basalt]

HangingBreakEvent

[amber vale]

I'd just wanna cancel the death event from running, but it isn't cancellable

[amber vale]

That's for when a player breaks it

[amber vale]

Tbh I have no clue how to do that

[echo basalt]

pretty sure there was a way

think it was just adding 16 in each direction and %= 15

or adding 15 and %= 16

something like that

[amber vale]

I feel dumb now

I have been at this for hours and tried to work with that event and it was that simple

Or I hope it works now atleast

[orchid gazelle]

Isn't that one comma too much?

[echo basalt]

Doesn't matter for enums

[amber vale]

I feel very dumb

lol

[orchid gazelle]

Bad practice, looks ugly

[amber vale]

Thanks

[echo basalt]

Your name literally means "beginner" in portuguese

Don't stress it 😛

[orchid gazelle]

Yes

[amber vale]

I'm aware, it comes from when I was like "hmm, what would be a good username... I'm really dumb sometimes, let's throw "Noob" into google translate and see if something nice sounding comes out... Ooh Novato that sounds smooth"

[pseudo hazel]

that extra comma is good actually

mostly for version control reasons

since then you only have to edit 1 line to add a new constant

[echo basalt]

So.. redundant

[pseudo hazel]

yes

but in a good way

I think its either a comma or a semicolon

unless its not needed

[echo basalt]

I'd expect it on the material enum not in some obscure event

[restive mango]

This plugin doesn’t actually make you lay down when you /lay

Though

It doesn’t put you in a bed view

Like in an MC bed

With the leave bed button

[remote swallow]

type /lay on a bed

[wispy jasper]

hey I have a question!
I want to make a command, which is only accessable for players with a specific tag. is that possible?
Or what else do I do?

[restive mango]

So it doesn’t handle that

[remote swallow]

doing that is just extra unneeded work

[echo basalt]

Break it down

[restive mango]

Yes…

[flint coyote]

Wdym by tag? Aren't permissions sufficient?

[restive mango]

I want to listen to the leave bed button packet

…

[wispy jasper]

its a server where you have different classes. I want to make a command for Fairys so they can fly and only players with the tag fairy can use it

[echo basalt]

Yeah so break it down

[flint coyote]

Make a fairy permission group and add them to the group when they chose the class. That would be the easiest.
You can however use the PlayerCommandPreProcessEvent to cancel command executions if you prefer that

[echo basalt]

That's just overcomplicated

make a command, couple checks to see the player's tag

if it's not fairy, throw an error message

[flint coyote]

that still makes the command show up for autocompletion since they have the permission

[wispy jasper]

yeah but idk how i do that xD you see i just started with this haha

[flint coyote]

Not that hard to run a command that adds them to a permission group once they pick the class

oh so the class plugin is not yours then?

[wispy jasper]

there are no commands to add me to the class yet. i just have some datapacks that give me custom team name and stuff if my ingame tag is like fairy

[opaque scarab]

Is running this asynchronously safe? world.getChunkAt(0,0).getChunkSnapshot()

[flint coyote]

yes

[orchid gazelle]

What does #getChunkSnapshot even do

[flint coyote]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/ChunkSnapshot.html

[orchid gazelle]

Huh can I just access it async and then process things with Chunk-Data?

[flint coyote]

Well in that case you have to work with that. I thought you made the datapack before.
You use the https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/event/player/PlayerCommandPreprocessEvent.html
and inside of it call #getPlayer() and check the tags. If they match you cancel the event

[flint coyote]

It basically creates a copy of the chunk, yes

[wispy jasper]

k thx

[orchid gazelle]

But completely async?

[opaque scarab]

If I’m creating an async pathfinding algorithm, should I use this to iterate through the blocks to determine pathfinding? Would that be a good method?

[flint coyote]

I think read operations are fine to be done async

So you don't need the snapshot

[flint coyote]

I never used it but I'd assume so

[orchid gazelle]

Thats great

[echo basalt]

nope

Snapshot's read only

snapshot's a read-only copy that's fine with async

[flint coyote]

I meant that you can do async checks on world.getBlockAt() as long as you don't modify it

[echo basalt]

pretty sure you can't

[opaque scarab]

How would I check block materials async then?

[echo basalt]

create a snapshot

for each chunk you're processing

And then you can check that snapshot's blocks async

[opaque scarab]

Oh sorry I misread what @flint coyote said

Thanks

[slow dagger]

Does anybody know how I can get a TrimMaterial/Pattern by inputting a String?

Example:
I have the String AMETHYST and want to get the corresponding TrimMaterial. How would I do it?

[orchid gazelle]

Imma do that with all important chunks on boot, thats great

[shadow night]

why does the event not fire

    @EventHandler
    public void onPlayerPickupItem(EntityPickupItemEvent event) {
        if(!(event.getEntity() instanceof Player player)) return;
        Bukkit.getPluginManager().callEvent(new PlayerItemAcquireEvent(player,
                event.getItem().getItemStack(),
                player.getInventory().first(event.getItem().getItemStack()),
                event.isCancelled()));
    }```

[flint coyote]

I just checked. It does work

[echo basalt]

ehh

icky then

SEARCH INDEX - Flood Fill code
https://sourceb.in/jVXf7tu3vr

[flint coyote]

Bukkit.getScheduler().runTaskAsynchronously(plugin, () -> System.out.println(Bukkit.getWorld("world").getBlockAt(0, 60 ,0).getType()));

this does work

and it even updates (I run it in the BlockBreakEvent)

[echo basalt]

something tells me you're running a funky paper fork

[flint coyote]

oh true, the server is based on paper since it boots up faster. Lemme check spigot

[opaque scarab]

Still might not be the best idea to work on something actively changing. Creating a snapshot allows you to work with a copy, without tampering with the original chunk itself.

[flint coyote]

Well if he just wants to create a path it probably won't change too much. But yes it comes with a little risk.
Creating a chunksnapshot is a pretty heavy operation though

[echo basalt]

Shouldn't be that heavy

[flint coyote]

did you register it? Does it implement listener?

[echo basalt]

That flood-fill code I posted managed to do like 300k blocks per second

single-thread was like 20k

[shadow night]

it is registered and it does implement Listener

wait, the event does not fire for some reason and I dunno why

[echo basalt]

Are both listeners registered

[opaque scarab]

In a pathfinding refresh, I only check a few hundred blocks, so would it be damaging to performance?

[echo basalt]

snapshots might be wasteful at a certain point

It's the kind of thing where you do both and make a graph

[shadow night]

here the other listener

being registered

[echo basalt]

mm I really hate this but it should work

[shadow night]

it should but it does not

[opaque scarab]

Wdym

[dim shell]

I really know nothing about coding plugins, but I have a little experience with datapacks, and I'm wondering if anybody can help me figure out how to make a custom plugin?

[echo basalt]

Let's say your distance between A and B is like 4 blocks

Making a whole snapshot can be wasteful

if at the end you only need to pathfind those 4 blocks

[shadow night]

I swear, spigot events are cursed

[echo basalt]

Might come across as arrogant but ?learnjava

b o t pls

?learnjava

[undone axle]

Here are some links to get you started on learning Java:

• https://www.codecademy.com/learn/learn-java
• https://www.sololearn.com/learning/1068
• https://www.learnjavaonline.org/
• https://programmingbydoing.com/
• https://docs.oracle.com/javase/tutorial/java/index.html

The last one is the only official one, however some of those concepts assume that you already know a bit about programming.

[echo basalt]

There ya go

[flint coyote]

something must be missing I guess

[shadow night]

what could be missing

[dim shell]

I know how to code java lmao, that doesn't tell me anything about integrating it with minecraft and plugins

[echo basalt]

Ah

[opaque scarab]

Ah makes sense. So should I just check the blocks directly then, without the snapshot copy?

Keep in mind, the pathfinder is running async

[echo basalt]

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

I'd start by reading the wiki

[dim shell]

and it doesn't help most plugin tutorials on youtube barely show anything more in depth past just responding to a certain phrase in chat

[echo basalt]

Well

That's.. the event system which is a good starting point

[flint coyote]

can't decide on building vehicles and start with a spaceship I guess

[echo basalt]

There are tons of events and the chat one is quite intuitive

So we start with the chat one

You can then just pick another event and play with it

Maybe get multiple listeners working together.. That's why youtubers make entire series

[flint coyote]

lemme just check the async thing on spigot then we can hop in a voicechat and check if you want to. Probably has to be a private call since no screenshare is allowed on spigot (for whatever reason)

[opaque scarab]

IDK if these are any good anymore, as I watched them a while ago. But this is what got me started https://youtube.com/playlist?list=PLDhiRTZ_vnoUvdrkTnaWP_hPmbj2JfPAF

[echo basalt]

Maybe some kind of config where it picks between async and sync

[dim shell]

Yeah that's fair, I'm trying to make one that I can't imagine not being fairly simple

[echo basalt]

Start slow and work your way up

I did try to make minigames at the 1 year mark and it just went poorly

And then again at the 3 year mark, slightly less worse

[dim shell]

Fair, I'm trying to make one that bares resemblence to the lifesteal plugin, but is pretty different

[flint coyote]

hearing "years" must really make people feel unmotivated but it's kinda true. Programming is a looong process

[echo basalt]

I've been coding for 12 years and making plugins for the past 6

[zenith gate]

i think hearing decades is worse lol

[shadow night]

oh gosh, spigot is cursed

[flint coyote]

Yeah I'm coding for 8-9 years now. Started with plugins like a year after. I did have breaks from spigot and coded other stuff though

[echo basalt]

Only now I decided to start touching minigames and making really really fancy particle effects

But once you have a good structure, things will flow smoothly

I made TNT tag in like an hour last night :p

[flint coyote]

did u find it?

[shadow night]

nope

just events not working for me like casual stuff

[echo basalt]

Add souts everywhere

[shadow night]

I'm doing that rn

[flint coyote]

boo

it does work on spigot, too @echo basalt

[echo basalt]

odd

[shadow night]

everything after registerListener isn't working

[flint coyote]

Why wouldn't it? It's a read-only operation

[shadow night]

maybe I should try it in a different

way

[echo basalt]

try reading at an unloaded chunk

[quaint mantle]

https://streamable.com/j7b50q

im working with just packets do I need to send a block back to the player when they break it?

(those blocks im right clciking and mining are packet based and client side)

[flint coyote]

Just like with files you can also have infinity threads reading it but only one can write

[opaque scarab]

I originally wanted to do the pathfinding async because if it took a while to process it wouldn’t delay vanilla server updates. What benefit would running it sync have?

[flint coyote]

that won't work. At least that's what I'd expect. Or just return air

[echo basalt]

less memory footprint

And maybe less spiking

[echo basalt]

When a player breaks a block, it sends a packet saying it has "finished digging" with the block position

And sets the block as air internally

[opaque scarab]

Good point

[echo basalt]

You can send the block back if you want, or just do whatever

[quaint mantle]

I cancel that https://pastebin.com/c7Vt7Eza

Don't I so spigopt never gets any packets related to those blocks

[flint coyote]

does work and seems to load the chunk (synchronously)

[shadow night]

this worked ._.

cursed stuff

[flint coyote]

I mean ofc you have to register both

[echo basalt]

You can't cancel the packet like that

It's a packet sent from the client -> server

cancelling it just means the server won't process it

[quaint mantle]

Yeah so spigot should never set it to air in theory?

[echo basalt]

When you cancel an event, it sends packets reverting the action

[quaint mantle]

yeah what packet do I need to send to revert them breaking a block?

[echo basalt]

This is what we did at work

[shadow night]

I just registered them the normal way instead of static register function and it worked

[remote swallow]

fourteen will scream at you for the static instance

[flint coyote]

a static function should work as long as it's called from the onEnable

[echo basalt]

the pixelated stuff?

[remote swallow]

yeah

[echo basalt]

Not my fault

[cinder abyss]

Hello, when I want to use BuildTools for 1.16.5, I get this errors :
https://pastebin.com/S9b1e5J4

[shadow night]

as you can see, it didn't

[echo basalt]

I only wrote the packet stuff, everything else was made by someone else and I didn't have time to DI everything

but honestly I already had an instance so idk

[flint coyote]

Weird thing that an asynchronous operation does a synchronous chunk load to access data. Still better than an error I suppose

[echo basalt]

maybe I'm just dumb

[shadow night]

what funny thing can I do in my onDisable

[remote swallow]

print out random millis that stuff take

[flint coyote]

wdym by funny?

[remote swallow]

eg, how long it took to register listeners, how long startup too, how long an event lasts, literally just a random amount of millus

[shadow night]

like, something to entertain me when I enter stop in the console and something confuse people who use my plugin

[echo basalt]

"You telling me that this server is stopping without a crash?"

[shadow night]

I should probably not say what is what and try guessing stuff

[flint coyote]

"You dare to shut me down?!"

[echo basalt]

or just generate some random numbers and claim it's a memory leak

[shadow night]

and also print it in a random sequence

[shadow night]

lol

[echo basalt]

"Data sent to the chinese government: 28.4TB"

[shadow night]

LMAO

I should do that

[remote swallow]

throw an exception every second on a new thread for the entire shutdown

[echo basalt]

just do new Throwable().printStackTrace

[shadow night]

that's cursed

I should make an error which will basically be "Server is shutting down, Error code: 0"

[remote swallow]

for (int i = 0; i < Integer.MAX_VALUE; i++) {
    new Throwable().printStackTrace();
}

[flint coyote]

Or you just add a random "common password list" and do some interesting fact aka "Did you know that McDonalds123 is a pretty common password?"

Gotta teach safety on disable

[cinder abyss]

can someone help me please ?

[shadow night]

uhh

[twilit roost]

okay so I have a center location
I want to find every block (EMERALD) with underlaying block (DIAMONDBL) connected to the center

what algorithm should I use to make it the most efficient?
Flood Fill?>

[flint coyote]

what command did you use to launch? It just builds latest for me when launching it without parameters

[flint coyote]

well start millis is less than current

[flint coyote]

Does 1.16.5 even support java 8?

[shadow night]

it does afaik

[flint coyote]

yup seems so

[cinder abyss]

yes 1.17 needs java 16 and 1.17.1+ needs java 17

[flint coyote]

did that script work before? Did you try calling
C:\Program Files\Zulu\zulu-8\bin\java -jar BuildTools.jar --rev 1.16.5 directly?

might need the quotes around the path, not sure.
In that case
"C:\Program Files\Zulu\zulu-8\bin\java" -jar BuildTools.jar --rev 1.16.5

[shadow night]

hehehe

[cinder abyss]

I'll try

[opaque scarab]

Next question of the day. How can I make an entity pathfind to a specific location?

[cinder abyss]

Same...

[flint coyote]

hmm did you try using another network? E.g. mobile data?

Also make sure to not use any VPN

[cinder abyss]

I'll try disconnecting my Eternet cable

(and using wifi)

[flint coyote]

That probably won't change anything. Try using your phones data, if you have that

[cinder abyss]

it's working

well

strange

[flint coyote]

weird, good for your though xD

[cinder abyss]

my pc is ethernitically not compatible I think

[flint coyote]

maybe an ant inside your ethernet cable is eating all the packets

[shadow night]

interesting theory

[remote swallow]

sorry it just tastes so godo

[cinder abyss]

Imagine

[shadow night]

yummy packets

[twilit roost]

what is the most efficient way to check if player stepped on a block of some type?

[flint coyote]

Probably an early return PlayerMoveEvent

Just make sure to use e.getTo() instead of player.getLocation()

[twilit roost]

oh right
tysm

[mellow pebble]

Hi guys so im making TablistManager which will just be used to put on header and footer to players tablist and most likely just put prefix to the players tablist so yeah i need ChatComponent type which comes with net.minecraft.server... so i had to add my server.jar as dependency to my project right and im using intellij and i went in project structure i found where my module is and i went in dependencies tab and added my server.jar as dependency but it seems not to be working for some reason i mean it is not loading as dependency so i cant use it in my project any help maybe if someone is familiar ?

[quaint mantle]

Well I changed it to also send a ClientboundBlockUpdatePacket to the player no still disappears

[fluid river]

newer versions use maven/gradle dependency

not a .jar dependency

also isn't component part of api already

oh it's paper shit

https://docs.advntr.dev/getting-started.html

you can use adventure then

[spare hazel]

Just looking for the javadocs

?jd-s

[undone axle]

https://hub.spigotmc.org/javadocs/spigot

[mellow pebble]

what is maven dependency for that

[fluid river]

?nms

[undone axle]

https://blog.jeff-media.com/nms-use-mojang-mappings-for-your-spigot-plugins/

[fluid river]

chatcomponents

part of adventure

[fluid river]

if you need nms, follow this guide

[quaint mantle]

Does anyone know what this packet is called ?

[mellow pebble]

PlayerAction myb

[quaint mantle]

I already tried that

Which is why I am asking

[mellow pebble]

you want to send that packet ?

[buoyant viper]

its Serverbound i think

unless ur trying to send it to other players uhhh idr

[quaint mantle]

oh shit u right it is Serverbound

[mellow pebble]

silly

[quaint mantle]

Do you know what the name is on packet events?

[tender shard]

mojang name is ServerboundPlayerActionPacket

does packet events not use the proper names?

[quaint mantle]

When you call the updateIniduvually how did you get that to work?

        (player as CraftPlayer).handle.connection.send(
            ClientboundBlockUpdatePacket(BlockPos(blockPosition.x, blockPosition.y, blockPosition.z), block!!)
        )

            Play.Client.PLAYER_DIGGING -> {
                val wrappedPacket = WrapperPlayClientPlayerDigging(event)

                if (!wrappedPacket.action.name.contains("DIG")) return

                Bukkit.broadcastMessage("Received a packet digging.")

                // TODO: we may need to send a block Ack packet (Agnowledge)
                if (BlockTracker.isPacketBlock((event.player as Player).uniqueId, wrappedPacket.blockPosition, (event.player as Player).world.name)) {
                    event.isCancelled = true

                    RenderHandler.updateSingle(event.player as Player, wrappedPacket.blockPosition, (event.player as Player).world.name)
                }
            }

[wet breach]

BlockDamageEvent

[quaint mantle]

On packet events? What

[wet breach]

not sure what you mean on packet events then, assumed maybe you wanted to know what it was in the api

[tender shard]

packetevents is a lib like protocollib

[quaint mantle]

using a bukkit like event system for packets

Im just tryna figure out why it is not stopping a block from being mined client side and not reppearing

[wet breach]

well there isn't much that can be done on the client side as the client still has predictive code

so it really depends

[quaint mantle]

but I send a block update to the client when they try and break the block?

do I need to be delaying by a tick or smth?

[wet breach]

if you don't want to deal with code for stopping a block from being mined

you could always set the NBT tag for it

[quaint mantle]

No I would like to deal with stopping a block from being mined

[wet breach]

but there is api methods though in spigot to stop such things, which is the blockbreakevent

[onyx fjord]

is there an event for new day in the world?

[quaint mantle]

yes but my blocks arent real

[wet breach]

so not sure why you are attempting to do this from the NMS at the packet level

[quaint mantle]

they are per player packet blocks

so spigot doesn't know that the blocks exist

[quaint mantle]

hmm thats the exact same thing im doing for the most part

[wet breach]

ah

I know your issue then

there is like 5 or so packets you are going to need to deal with then

[quaint mantle]

I deal with block place and dig

[wet breach]

any updates to the chunk or blocks need to be intercepted

[quaint mantle]

yes

Im gonna do that later im tryna get this issue fixed rn

[wet breach]

if any of these packets makes it to the client, the client will realize your blocks are fake and remove them

[wet breach]

nope, this is your issue

[quaint mantle]

it is not

oh

actually it might be

[wet breach]

chunk updates for example

there is 2 packets for that

[quaint mantle]

minecraft sends the whole chunk? when u break block/

[wet breach]

yes

but not only that

[quaint mantle]

i see

[wet breach]

the server sends neighboring chunk updates too

so if you break a block in 1 chunk, it could send updates for 4 other chunks too

but chunk packets are not the only things that cause the client to update either

there is a few other packets which I don't remember them all

[quaint mantle]

ty for that I will skim wiki.vg for the others

I didnt even think that this would break this exact issue

[quaint mantle]

Wait this shouldn't break this tho since minecraft never would update the chunk when I break a block

since only I know this block exists

[wet breach]

the client sometimes requests

so you have to listen to both inbound and outbound

[river oracle]

I'm still trying to figure this out. How the hell do I correct for the coordinates being off from what I want at chunks in a predictable manner.

(1215, -895) reduces into (75, -56) [this is intended]
(75, -56) expands into (1200, -880) [this is not intended]
I need to find a solution to get (1200, -880) to become (1215, -895)

(1168, -848) reduces into (73, -54) [this is intended]
(73, -54) expands into (1168, -863) [this is not intended]
I need to find a solution to get (1168, -863) to become (1168, -848)

this is the code I'm using to get into a bounding box

    public BoundingBox asBoundingBox() {
        final World world = Bukkit.getWorld(this.corner1.getWorld());
        if (world == null) {
            throw new IllegalStateException("The world of this area is not loaded");
        }

        Location lc1 = corner1.asLocation(world.getMaxHeight());
        Location lc2 = corner2.asLocation(world.getMinHeight());
        return BoundingBox.of(lc1, lc2);
    }```
```java
    public Location asLocation(final int y) {
        final World world = Bukkit.getWorld(this.world);
        if (world == null) {
            throw new IllegalStateException("World of location is not present");
        }

        return new Location(world, this.x << 4, y, this.z << 4);
    }

[echo basalt]

probably something to do with lowest possible corner

[upper hazel]

who know c++ help me

[river oracle]

I don't think so

wait

[river oracle]

yeah its def that

before there was a bug in my code causing it to be off even more, so I just noticed

[upper hazel]

how to scammer cpp folder through visualStudio cpp files it doesn't see

[river oracle]

the hard part here then would be how do I preserve the lossy operation of blockX >> 4 because I don't technically know where my post is. All I know is they form a square

[echo basalt]

add 15

[river oracle]

works in some cases and not others no?

I mean in one of my examples its only off by 15, the other one is off by 15 in each direction

wait

yeah no I'm still stumped

I mean if its different in each scenario idk what to do

[echo basalt]

wait so is it still that opposing corners thing

[river oracle]

yeah I need to get the points where the 2 corner chunks are furthest apart

[echo basalt]

just add 15 in the relative X and Z axis and %= that by 16

Basically just

int relX = x - chunkX * 16
int relZ = z - chunkZ * 16

int oppositeX = chunkX * 16 + ((relX + 15) % 16);
int oppositeZ = chunkZ * 16 + ((relZ + 15) % 16);

don't ask why it works

might cause weird issues actually

[river oracle]

I would do this with both corners right

[twilit roost]

I start where the red block is
I want to get blocks that connected in someway to the main location and are Emerald blocks

this is my current run on the Flood-Fill, but it results in absurt big results:

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

[echo basalt]

yeah sure

[river oracle]

lest hope it works

[echo basalt]

Here's code for a flood fill

[twilit roost]

oh my
tysm

[echo basalt]

It's optimized for large areas

pretty sure I ran it on areas that were a few million blocks in volume

You'll also need a main thread executor

[twilit roost]

ye thats not a problem

since u know the code better
how could I adapt it to also check the block below the upper block and only add if it's Diamond Block?

[wet breach]

this works because chunk coords are only divisible by 16

[timid hedge]

Why am i getting so many errors with this?
It dosent understand: e.getAction(), e.getClickedBlock(), b.getType(), b.getType and b.getState

[tender shard]

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

because none of those methods exist

(for the event, that is)

[timid hedge]

Im using 1.8

[tender shard]

they also don't exist in 1.8

[river oracle]

is x and z the x and z I want it to be on?

[echo basalt]

ye

[river oracle]

I don't know that kind of but, the code you gave does have a side affect which is beneficial an idea

[upbeat fog]

I have an issue again with this plugin, so what I wanted to do was when a player has a certain helmet on, it gives a 10 percent change to give double drops. But it doesnt recognize that I have the helmet on or doesnt run the code thru.

[tender shard]

identify your custom items through PDC tags

[upbeat fog]

PDC tags?

[tender shard]

https://blog.jeff-media.com/persistent-data-container-the-better-alternative-to-nbt-tags/

you could just store a boolean in your item, e.g. "is-my-custom-helmet"

private isMyHelmetKey = new NamespacedKey(myPlugin, "is-my-custom-helmet");

// Save tag on item
ItemMeta myItemMeta = myHelmetItemStack.getItemMeta();
myItemMeta.getPersistentDataContainer().set(isMyHelmetKey, PersistentDataType.BOOLEAN, true);
myHelmetItemStack.setItemMeta(myItemMeta);

// Check if its your custom helmet
if(myItemMeta.getPersistentDataContainer().has(isMyHelmetKey, PersistentDataType.BOOLEAN)) {
  // It is my helmet!
}

nobody there uses "getAction()" or "getClickedBLock()" on a SignChangeEvent

[timid hedge]

There is
Of you scrool down on the code at onInteract you can see if (e.getAction() == Action.RIGHT_CLICK_BLOCK)

[twilit roost]

im dumb af
I adapted it a bit to also check for bottom block if it matches another material

but I can't seem to get it to work at all
it just created CFs and does nothing

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

[echo basalt]

modifying is at your own discretion ¯_(ツ)_/¯

[upbeat fog]

@tender shard still nothing lmao

[tender shard]

show your code
