[young knoll]

If you want them to be broken in a certain time like normal blocks, that’s a bit more advanced

[quaint mantle]

You can do Block#getBreakingSpeed and add the total progress and check if it's over one

[hybrid spoke]

change the texture to wood to make it breakable

[quaint mantle]

But I think that always returns 0 when the block is unbreakable

God

[ancient plank]

Send a fake block and when they break the fake block break the bedrock

[echo basalt]

[young knoll]

Just don’t have bedrock in the world

Problem solved

[ancient plank]

True

[hybrid spoke]

dont have blocks in the world

[quaint mantle]

[torn shuttle]

lmao seriously

[delicate lynx]

don't run a server

[young knoll]

Don’t have world

[hybrid spoke]

or break every block a player looks at

[lost matrix]

Have fun. Took me a while to figure out

[haughty storm]

What do i have to put as the second argument for the World#spawnFallingBlock(Location, Blockdata) for it to spawn a Magma Block?

[delicate lynx]

BlockData

[young knoll]

Material.MAGMA_BLOCK.createBlockData

[hybrid spoke]

thought its free rotatable

[haughty storm]

thx

[torn shuttle]

did you figure it out in the end?

[lost matrix]

Kind of. Im still trying to figure out why you need two linear transformations.
Because there is no imaginary space we can work with. Only a real one.

[native gale]

How do I get the second part of the bed when BlockMultiPlaceEvent is fired?

Ok, you can obtain it via getReplacedBlockStates

[torn shuttle]

is there even a reason to avoid doing the interpolation yourself?

this seems like a lot of effort for something that seems hard to justify

[young knoll]

But smooth on client

[hushed pawn]

i know in hypixel duels there is few arenas in one server. whats a good way to create same structure and manage such arenas (specially load/unload worlds)?

[bitter steeple]

NBTTagCompound not existing anymore?

[lost matrix]

Dont bother with loading/unloading worlds.
Spigot will lag and there is no way around that.

[torn shuttle]

that's another thing too, if I have a transform and change the transform halfway into it to reflect a new state and do that a bunch of times but clients are running slow, how do they catch up?

[sacred wyvern]

With the Spigot Config Is it better to using a String index for a lists or should I use an ArrayList and parse?

[wet breach]

are you sure they are in one server?

[young knoll]

Yeah they run a few of several games on one server

[wet breach]

but how can you be certain of that o.O

[sacred wyvern]

I'm trying to make the autocomplete dynamic and simple to generate but the ArrayList was requiring a lot of parsing. I tried looking around on forums and got both being recommended.

[torn shuttle]

hasn't their shit been leaked a few times?

[wet breach]

not that I am aware of, if it has nothing that wasn't like important

but I have a general idea in how hypixel does their stuff

[young knoll]

In the past there have been bugs to leak chat and game messages between games on the same server

You can also get watchdog removal messages when it’s no one in your specific game

[wet breach]

chat isn't an indicator that you are on the same server

[young knoll]

Well sure

But it’s way more likely they let chat slip from another game on the same server than another sever entirely

[wet breach]

doubt it

[young knoll]

Plus some of their games are very small, it would be a waste to use 1 server per game

[wet breach]

it would be far more optimal to leverage the single threaded nature of mc then it would be to stuff a single server with several games

[wet breach]

how so?

[torn shuttle]

assuming that a minigame is going to max your thread out is a fun assumption

[wet breach]

you are also assuming the OS wouldn't use the freed up space either

[torn shuttle]

I have no clue why this uses two quaternions

[hushed pawn]

its around 8 arenas on one server

as far as i know

hosting 500 servers each for every duel game would be not that cheap

[young knoll]

Yeah duels is a good one to have multiple on 1 server

Since they are tiny games

[lost matrix]

How scalable do you need this to be?
I would suggest simply having one world with 8 Arenas in them.

[hushed pawn]

yes, but how to manage worlds, im trying to find best way

ah

i mean

[lost matrix]

Then create an Arena class with a BoundingBox and a Set<UUID> for participants
And an ArenaManager which manages those arenas. Maybe in a Map<String, Arena> where the key is the name of the Arena.

[hushed pawn]

one world with arenas? but none of big servers done it by this way

[lost matrix]

You wouldnt know if they did.

[hushed pawn]

cords on hypixel are the same on every map

same thing in mineman

[lost matrix]

Not an argument. Also: You are not Hypixel.
If you want to "do it like Hypixel" then start writing your own server
software. Dont use Spigot. Fork it and create a dedicated jar just for
minigame instances.

[hushed pawn]

why not?

an argument

[lost matrix]

Because in theory you can have multiple players have the same coordinates on the same world
but perceive completely different game states. *Assuming you have a highly modified jar like Hypixel.

[wet breach]

yes they have and they do. When you start becoming a large network, you have to do things differently. Its not the same as a small network where you are restricted to only the limited resources you have.

[quaint mantle]

Whenever calling the following, if the hidden player eats, does the eating sound gets passed to the other player? https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/Player.html#hidePlayer(org.bukkit.plugin.Plugin,org.bukkit.entity.Player)

is there any plugin which automatically rekit a player when a player kills another player?
if anyone have it please give me ill apricate it

[hushed pawn]

btw there is no good ways to manage worlds in this way?

[lost matrix]

But again: You dont need to scale that way. They are using a fk ton of technology
for load balancing. They dynamically start servers, load worlds etc depending on
how many players are trying to play something.

[wet breach]

you are under the assumption that every server would need to have 10gb of ram or something, when this is not the case, the amount of ram you would need to allocate if it was just per server for a small minigame tends to be lower then if you tried to stuff a single server with many games

[quaint mantle]

I am not asking about what's the behavior, but the expected behavior instead. Like, should we expect the API to hide the eating sounds as well or is this feature not intended?

[wet breach]

and 7smile7 is correct in what hypixel does, as well as they have their own fork for servers

[lost matrix]

Only if you load a ton of worlds when the server starts. Loading and enabling worlds on runtime
lags out a Spigot server because all of this is done on the main thread.

[young knoll]

I wonder how that instanced dungeon plugin handles it

[wet breach]

the main problem with having multiple worlds for games, is the fact you can't fully unload them without modifying the server code to cleanly do it

[quaint mantle]

This is my assumption of how Hypixel bedwars work. So each server runs multiple worlds which are exact duplicates of a file and then splits players between worlds. So each arena has a world dedicated to it. Whenever the arena is done, I think it marks the world as dirty (which means that changes have been made, like it's no longer clean). At some point, it will no longer be viable so it marks the server instance to removal and will no longer accept new players for arenas and will just request a new server instance to the cloud provider.

It's simple even when it doesn't. So Hypixel still makes use of multiple worlds per server. This has been demonstrated in their Skyblock gamemode. Don't lie yourself!

hello.

how do i make an async function sleep?

um

[smoky oak]

on async you can just call sleep

[quaint mantle]

is it just Thread.sleep();?

[wet breach]

no

[tardy delta]

schedule a task in a task

[smoky oak]

why cant u make an async task sleep

i mean isnt it async

[quaint mantle]

what?

[wet breach]

doesn't mean it gets its very own thread

[young knoll]

It uses a thread pool

[wet breach]

there could be other tasks on the same thread

[ivory sleet]

ye that works

[quaint mantle]

players might be able to break stuff while stuff gets processed (there is disk io going on) if they spam stuff, so i need to put the thread to sleep until stuff gets processed.

[smoky oak]

if you say it works, does sleep just suspend the thread from the pool for that long?

[tardy delta]

while (true) Thread.yield() :)

[smoky oak]

cant you use a lock then?

[ivory sleet]

it just sleeps the thread lol

[lost matrix]

Why do you want to do that?

[torn shuttle]

was mojang smoking some kind of crack when they came up with the way these display entities rotate?

[ivory sleet]

if the thread is in a pool too bad

[quaint mantle]

private HashSet<Player> playersBeingProcessed = new HashSet<Player>();
while (playersBeingProcessed.contains(player)) {
                    Thread.sleep(50);
                }```

[young knoll]

I mean it would only be a problem if you sleep every thread in the pool, no?

[quaint mantle]

this is how i am trying to do it.

[lost matrix]

Dont do that

[quaint mantle]

I think it's just JOML

[quaint mantle]

why not?

[ivory sleet]

that's ehm not a good design

[wet breach]

its a problem if you have other tasks that are part of that thread

[ivory sleet]

smile tell em

[quaint mantle]

i need to stop the player from spamming stuff.

[young knoll]

Do tasks get assigned to a thread for their entire lifetime

[hazy parrot]

So check it when they try to spam

[ivory sleet]

maybe use a cyclicbarrier or semaphore

[quaint mantle]

a what?

[lost matrix]

You are burning valuable processing power. This is just a glorified room heater in code form.
Use a CountdownLatch or Mutex to notify when the processing is done.

[young knoll]

Or does a thread just get picked from the pool whenever a tasks executed

[wet breach]

a worker thread can process multiple tasks

[quaint mantle]

its async?

[torn shuttle]

why require the initial rotation at all? Why do we have to calculate it ourselves?

[quaint mantle]

why does it matter? stuff just runs asynchronously, right?

when the thread sleeps, the cpu processes other stuff though, right?

[torn shuttle]

oh is it because it doesn't strictly have to be its actual starting point? I think I see what's going on

ok

[quaint mantle]

why?

does not that mean it is blocking or something like that?

[wet breach]

what do you mean why?

[quaint mantle]

nvm.

[torn shuttle]

alright now I get why this is like this

[quaint mantle]

Are you writing a wrapper for it?

[torn shuttle]

not sure if I will use it at all, I was going to just implement my own thing

[wet breach]

threads are not created for every task that gets scheduled this isn't feasible. Hence there being a thread pool

[torn shuttle]

smooth animation is cool but I don't know what will happen when things start getting desynced

[quaint mantle]

If someone's doing a wrapper for doing easy transformation and such without needing to do complex math ops I will star their project 🦾

private HashSet<Player> playersBeingProcessed = new HashSet<Player>();
if (playersBeingProcessed.contains(player)) {
    return;
}```

is this okay?

[tardy delta]

what are you even doing

[torn shuttle]

the only wrapper you need is for the singular value decomposition

[quaint mantle]

            Bukkit.getScheduler().runTaskAsynchronously(ChunkClaimsPlugin.getThisPlugin(), () -> {
                Player player = (Player) event.getWhoClicked();

                if (playersBeingProcessed.contains(player)) {
                    return;
                }

                playersBeingProcessed.add(player);

                // some code runs here probably.

                playersBeingProcessed.remove(player);
            });```

is that okay?

[wet breach]

What would be better to do, would simply make your code just exit the code block if a condition hasn't been met for it to run

[tardy delta]

if (!remove)

wait you are checking contains, adding and removing there 😵‍💫

[lost matrix]

public class AsyncPlayerProcessor {

  public AsyncPlayerProcessor() {
    playerQueue = new ArrayDeque<>();
    notification = new CompletableFuture<>();
  }

  private Queue<Player> playerQueue = new ArrayDeque<>();
  private final CompletableFuture<Void> notification;

  // Is called from one thread
  public void processNext() {
    Player nextPlayer = playerQueue.poll();
    if(nextPlayer == null) {
      notification.complete(null);
    }
  }

  // Anyone can get this and wait for the process to finish
  public CompletableFuture<Void> getNotification() {
    return notification;
  }

}

Example one

[quaint mantle]

i am implementing a spam protection.

while stuff gets processed.

spamming the command might break stuff.

[wet breach]

you could just implement a command delay based off how long ago they used it

[quaint mantle]

is this not just that?

[lost matrix]

public class AsyncPlayerProcessor {

  public AsyncPlayerProcessor(Collection<Player> players) {
    playerQueue = new ArrayDeque<>(players);
    notification = new CountDownLatch(players.size());
  }

  private final Queue<Player> playerQueue;
  private final CountDownLatch notification;

  // Is called from one thread
  public void processNext() {
    Player nextPlayer = playerQueue.poll();
    if(nextPlayer != null) {
      notification.countDown();
    }
  }

  // Anyone can get this and wait for the process to finish
  public CountDownLatch getNotification() {
    return notification;
  }

}

With this you even have a counter on how many players are left for processing

[ivory sleet]

mapping timestamps :o

[quaint mantle]

plus, i cant just have an arbitrary delay, i need the task to finish first.

[wet breach]

you don't need to iterate anything if you are only dealing with timestamps

[wet breach]

what task might that be?

[quaint mantle]

there is disk io going on, i am fetching stuff from a database and it takes a while and between delays, if the thing is triggered again, it seems to be causing issues.

[torn shuttle]

fyi I just checked and apache commons 3 does that for you

[wet breach]

your DB is consuming disk IO? o.O

[lost matrix]

Then use a CompletableFuture. Its the easiest way to wait for one task to finish and work with the result

[wet breach]

what are you doing using sqlite?

[quaint mantle]

yep, sqlite.

[lost matrix]

Every DB uses Disk IO...

[quaint mantle]

oh yeah, right, most dbs use network io, if they are not on the same machine probably.

[wet breach]

use mysql or mariadb if you are having this much of an issue with IO

sqlite is not scalable

[torn shuttle]

cool kids put their db on ram

[wet breach]

nor was it meant to be

[lost matrix]

sqlite for me is just a fallback DB for when someone doesnt have a proper DB installed

[wet breach]

this is true, but I am fairly certain mysql uses less then sqlite does

[quaint mantle]

yep, those can also be probably, probably can just use the same sqlite code for mysql/mariadb.

[fresh timber]

how do I give a player a permission?

[quaint mantle]

just have to change the jdbc url to do that perhaps?

[wet breach]

most of the sql stuff is the same with only some minor differences for a few things

[quaint mantle]

problem for later probably.

[wet breach]

jdbc url would indeed need to be changed

[quiet ice]

I believe there are DBs (such as hazelcast) that are meant to minimise the impact of Disk I/O to be a non-issue

[wet breach]

but sqlite is not designed to be used on a large scale or storing massive amounts of information

[quaint mantle]

i would probably just have compatibility for sqlite and mysql, that is probably it.

somebody told me sqlite can handle like 2 million transactions or something.

[lost matrix]

Hazelcast is just memory clustering really... Wouldnt even call it a DB

[quaint mantle]

its probably not meant for multiple connections.

[lost matrix]

But yeah there are in memory DBs

[quiet ice]

Wasn't too aware of what it is

[wet breach]

its not possible to have multiple connections for sqlite

[quaint mantle]

since you may not be able to use more than one application to access the file.

[quiet ice]

I just know that maven can use it for file locking for whatever reason

[quaint mantle]

yep.

[wet breach]

the reason its not possible is because sqlite requires a file handle

[lost matrix]

🤨 I didnt

[wet breach]

how large is your sqlite DB?

[quaint mantle]

so i just queue players to be processed, but how do i check if the player triggers the event again, they are being processed currently or not?

[wet breach]

size on disk that is

[quaint mantle]

probably a few thousand records in some tables, idk.

[wet breach]

no I mean actual file size

[quaint mantle]

probably not that bad.

[quaint mantle]

its not deployed yet.

i mean it might have a few thousand rows.

[wet breach]

if you want to make IO on disk a non-issue mount the file into a ramdisk

same the ramdisk periodically to hard disk every so often

[quaint mantle]

i feel like this xy problem.

disk io is not my problem.

i need to prevent players from spamming sutff, which seems to be no longer a problem nvm.

[wet breach]

you are the one using a system not designed to be scaled in this way, all I am doing is providing you a bandaide solution that will work for the time being

[quaint mantle]

uh...?????

[wet breach]

ramdisk is in memory only, and having the file in memory at all times means fast access and virtually no IO on the hard drive except every so often to save it back to hard drive

since your sqlite file is most likely going to be small, odds are you only need at most like 100-200mb ramdisk

[quaint mantle]

i am probably going to providing mysql compatibility.

[tender shard]

Add a PermissionAttachment

[young knoll]

Or hook the vault api

[quaint mantle]

but i still dont have disk io problems, at least none i have discerned yet.

[quaint mantle]

How that?

[tender shard]

But that‘d require vault :p

[lost matrix]

When using a latch: Check if the latch is at 0
When using a CF: Check if the CF is done

[wet breach]

you are the one that said you needed to pause stuff because of IO

so...now IO is not an issue?

if IO is not an issue, I don't see a reason to pause stuff since that was the premise of the whole problem

[young knoll]

I mean if you use an attachment

You have to save it don’t you

[tender shard]

Yeah sure, i thought they wanted to do a permissions plugin or sth

[quaint mantle]

ok it seems to be working fine now for the most part.

java should probably consider some functional programming like some of the web development libraries like react.

[lost matrix]

do you even pay for college in germany? is it free like healthcare despite being so much better than america perhaps?

Yes but I might switch to 1.16.5 or smt

[lost matrix]

Well step one would be to update. Not many people remember how to do stuff for legacy versions.

[young knoll]

1.12 doesn’t have looms

[torn shuttle]

its seems like you haven't tried anything yet so I would recommend you start with step 0 by trying to visualize the loom for the next 10 hours with your eyes closed and away from discord

[lost matrix]

This segment does nothing. We have no idea what you are doing.

[twilit roost]

turning long into timestamp

[lost matrix]

Yes, looks ok. But make SimpleDateFormat a field

Wait does DateFormat also format time?

[twilit roost]

¯_(ツ)_/¯

[lost matrix]

You might need a DataTimeFormatter

String timeColonPattern = "HH:mm:ss";
DateTimeFormatter timeColonFormatter = DateTimeFormatter.ofPattern(timeColonPattern);

[fresh timber]

so if u store info in a player entity PDC and the player leaves the server afterwards and rejoins, does the data get wiped or does it stay?

[lost matrix]

Wouldnt be a very persistent PersistentDataContainer if it would just vanish, would it

[fresh timber]

hmmm

so it vanishes

[quaint mantle]

how do i delete a world?

since world.getWorldFolder().delete() just gives me an error

[lost matrix]

[lost matrix]

[lost matrix]

1. First unload the world
2. What error

[bold gorge]

Just saying, your performance guide is nice

[quaint mantle]

thats a very good question what error it is

[wet breach]

Just because we are here in this discord doesn't mean we don't have jobs and other things

some are going to school in regards to programming as well

also

not everyone is young either lol

[quaint mantle]

ok so no error it just doesnt delete the folder, it does unload it but no delete

[sage patio]

How can i replace something in a string in a string builder?

[wet breach]

by using replace

[lost matrix]

You need to wait for some time after unloading. Spigot doesnt notify when world unloading is done.

[ancient plank]

Frostalf is the old one

[sage patio]

int start, int end, string?
i can't understand

[twilit roost]

aight tysm

[quaint mantle]

do i just wait like 100 ticks

[lost matrix]

Yeah should be fine

[torn shuttle]

the main issue I see with the client-side interpolation is that I have no clue of how I'm going to reconcile it with what is at its basis a moving entity

[grizzled oasis]

Im trying making a gui with an Open and Close system, for updating the gui when someone runs the command and update it for everyone in the server, but only the people who have open it how can i do that?

[quaint mantle]

Bukkit.unloadWorld(world, true);

            Bukkit.getScheduler().runTaskLater(plugin, () -> {
                world.getWorldFolder().delete();
            }, 100);

is this the correct way to delete a world?

[sage patio]

inventory.getViewers?

[quaint mantle]

cus i couldnt find anything else on it

[grizzled oasis]

and loop them and reopen the inventory

[lost matrix]

Your gui system should have a Map<Inventory, InventoryHandler> or something similar for your GUIs.
So iterate over all players, get their open inventory, check if its your GUI through the map and update it.

[young knoll]

There is sadly no callback for when a world successfully unloads

[lost matrix]

Does everyone have the same Inventory instance open?

Well... then just change the content of the inventory.

[wet breach]

this implies that there can be an unsuccessful unload

[young knoll]

Probably

[sage patio]

for (HumanEntity entity : inventory.getViewers) {

}

[young knoll]

Actually, yes

You can't unload the main world

[lost matrix]

Hm? A Future<Void> would be enough

[lost matrix]

No need to reopen anything imo

Just edit the Inventory

[sage patio]

^

[sage patio]

?

[wet breach]

they were saying there is no callback for a successful unload, was just stating that would mean there is a such thing as an unsuccessful unload as something being normal

[wet breach]

which it isnt lol

the exception being the main world

[young knoll]

I mean the current method returns a boolean already

[tender shard]

why the heck is this not enabled by default ><

[wet breach]

makes it easier to do some action after it unloads

[young knoll]

How does the current method even return a boolean instantly

If unloading isn't instant

[quaint mantle]

doesnt seem to work

[worldly ingot]

StringBuilders aren't really meant to replace things. If you really absolutely need to do it, you can call indexOf("the string you want to replace"), then replace(index, sizeOfString, "the thing you want to replace with")

[wet breach]

because it will unload, we don't need to wait till it is done doing that to return the boolean. As I said what you are implying is that it would be normal to have an unsuccessful unload lol

[sage patio]

i was doing that wrongly, i was replacing the builder not the String inside it

[worldly ingot]

StringBuilder builder = new StringBuilder("foo bar baz");
int index = builder.indexOf("bar");
builder.replace(index, index + 3, "blah");```

Arrays.asList("hello", "world")

[young knoll]

If you want to keep the current stuff you need to get it and then append

List<String> current = config.getStringList(key)
current.add("poop")
config.set(key, current)

[tender shard]

List<String> message = getConfig().getStringList("message");
message.add("test");

[young knoll]

Okay well alex's is more accurate

But mine says poop so

[lost matrix]

Coming back to this...

Thats a list of lists

Coderino pls

Arrays.asList now creates a List<List<String>>

just pass nicknames

[wet breach]

nicknames is already an array

[lost matrix]

List<String> nicknames = configuration.getStringList("message.nicknames");
nicknames.add(player);
configuration.set("message.nicknames", nicknames);

[wet breach]

since you obtained it as a stringlist

Any ideas why this error occurs?

[lost matrix]

This code does not relate to your error.
Also: What are you doing? What are you tinkering with the PlayerConnection?

[rough drift]

you need to recursively loop over the file structure and delete files first, then folders from the bottom up

[quaint mantle]

ahh okay

[quaint mantle]

PlayerConnection#NetworkManager is private in 1.19.4, and there is no getter for it

[rough drift]

public void deleteFolder(File folder) {
for(File file : folder.listFiles()) {
  if(file.isDirectory()) {
    deleteFolder(file);
    return;
  }

  file.delete();
}
}
``` @quaint mantle Something like this (really simple code, you should do error checking, and safety checks if the files are null)

[small timber]

did it

still throws the same error

[lost matrix]

No idea what those classes are supposed to be. Are you using Spigot mappings?

I don't think he's actually using the maven panel.

Your run configuration is botched

[lost matrix]

Just compile by using package

This compiles your plugin

ok thx

To fix your "run" button your would need to edit this:

Why not just set a default goal in your pom and use the maven run button?

I find a protocol lib but it's old on spigot web

And the via version same thing

[torn shuttle]

so is it possible in theory for fireworks to get stuck inside of blocks?

it seems like someone reported to me that they have over 1k lingering fireworks

[lost matrix]

Shouldnt they explode after a certain amount of ticks alive?

[torn shuttle]

see that's what I thought

it's like I'm spawning them in unloaded chunks or something but that doesn't make any sense

oh

[eternal oxide]

do you spawn them with a velocity?

[torn shuttle]

are they getting shot into unloaded chunks maybe?

that could do it

yeah some of these are angled

[eternal oxide]

that could do it

[torn shuttle]

so fun question

if I set it to not be persistent, will it be smart enough to remove itself if it goes into an unloaded chunk?

[lost matrix]

Yes

Wait

Probably

[torn shuttle]

I've been up for way too long, that's good enough for me

[honest relic]

@remote swallow @kind hatch I get the same problem

[hasty prawn]

WorldGuard does polygon regions though, doesn't it?

It doesn't look nearly as cool but I'm fairly certain it's capable of them

[lost matrix]

Since when

[kind hatch]

At least 1.12, but I don't think it was capable of triangle regions.

Not sure if it is even now

[hasty prawn]

Maybe not, but if you make a polygon selection with WorldEdit and just define a region with that, it works (iirc anyways)

[kind hatch]

They are a pain in the ass to setup though.

[hasty prawn]

They absolutely are yes

[lost matrix]

Oh yeah you can do elipsoids etc. But can you define N points and an arbitrary polygon within that?

[hasty prawn]

Yes

[kind hatch]

There was some command that you could bind to the selection tool that would set the points.

[lost matrix]

Eh mine is still cooler 🤷

[honest relic]

Solve my problem What is the use of you if you can not solve a simple problem like this problem

[lost matrix]

AAAHAHAHA XD

[hasty prawn]

Yeah I don't remember the command but you definitely can do it. It takes forever though and afaik there's no way to have a visual aspect to it.

[kind hatch]

Damn, he's coming on to me.

[hasty prawn]

So... still really epic looks cool af👍

[lost matrix]

Update your server and plugin versions and then come back if it still doesnt work.

[honest relic]

I've already done everything but it keeps giving me the same problem

[lost matrix]

What server version?

[kind hatch]

Have you tried a different client?

[honest relic]

@lost matrix
1.19.4 spigot

[honest relic]

Yes

[kind hatch]

Keep in mind that 1.19.4 only came out like 2 days ago. It'll take time for plugins to update. ProtocolLib might still be usable up to 1.19.3

[honest relic]

good thank you

[lost matrix]

Then go to ProtocolLib and ViaVersion and look at the supported versions.
1.19.4 is not production ready and should only be used for test versions.
Many plugins dont have updated their code for that version.

A bit clownish calling us useless when he simply refuses to read plugin descriptions

[sage patio]

how i can calculate this (i know i described badly)
50 / 10 = 5
51 / 10 = 6
59 / 10 = 6
60 / 10 = 6
61 / 10 = 7

[lost matrix]

flooring the number

[kind hatch]

Modulus?

[sage patio]

what is that

[kind hatch]

Flooring the number is like rounding down.

But on the decimal scale

[honest relic]

I need a solution to the problem. I have a Minecraft server, and now it does not work, and it must be on the latest version, because the members of the Minecraft server have a new version.

[kind hatch]

So 5.1 - 5.4 would floor to 5

[sage patio]

but my numbers are Integer

[quiet ice]

Math.ceil(number / 10.0D)

[sage patio]

thanks

[quiet ice]

Make sure to have either double or float division

That being said beware of floating point shenanigans

[lost matrix]

  public static void main(String[] args) {
    for(int i = 0; i < 50; i++) {
      int floored = (int) Math.ceil(i / 10.0);
      System.out.println("Number: " + i + " Floored / 10: " + floored);
    }
  }

Number: 26 Floored / 10: 3
Number: 27 Floored / 10: 3
Number: 28 Floored / 10: 3
Number: 29 Floored / 10: 3
Number: 30 Floored / 10: 3
Number: 31 Floored / 10: 4
Number: 32 Floored / 10: 4
Number: 33 Floored / 10: 4
Number: 34 Floored / 10: 4
Number: 35 Floored / 10: 4
Number: 36 Floored / 10: 4
Number: 37 Floored / 10: 4
Number: 38 Floored / 10: 4
Number: 39 Floored / 10: 4

[kind hatch]

Why must it be on the latest version? Again, it only came out 2 days ago, so updating immediately is kinda foolish since not everything has updated.
If you want a solution, just use ViaVersion on 1.19.3 so 1.19.4 clients can connect.

[quiet ice]

one can't really call that flooring if you are ceiling

[lost matrix]

Well thats not floored its ceiled...

Yeah language barrier kicks in

ceiling is up, floor is down ^^

[young knoll]

Shoutout to worldguard for having a nice easy API for what I need

[kind hatch]

What's the process for setting the points? Curious to see if it's similar to how worldedit handles it or if it's simpler.

[young knoll]

Most protection plugins don't let you query an entire area easily :c

[lost matrix]

One moment

[lost matrix]

For me its just

public AbstractRegion getRegionWithHighestPriorityAt(Location location) { ... }

[young knoll]

Nah I want to query a cube

Without iterating every single location ideally

Worldguard lets me do

public boolean canBuild(Player player, BoundingBox bounds) {
        LocalPlayer localPlayer = worldguard.wrapPlayer(player);

        if (WorldGuard.getInstance().getPlatform().getSessionManager().hasBypass(localPlayer, localPlayer.getWorld())) {
            return true;
        }

        RegionManager regions = CONTAINER.get(BukkitAdapter.adapt(player.getWorld()));
        BlockVector3 min = BlockVector3.at(bounds.getMinX(), bounds.getMinY(), bounds.getMinZ());
        BlockVector3 max = BlockVector3.at(bounds.getMaxX(), bounds.getMaxY(), bounds.getMaxZ());
        ProtectedRegion dummy = new ProtectedCuboidRegion("dummy", min, max);

        ApplicableRegionSet set = regions.getApplicableRegions(dummy);

        return set.testState(localPlayer, Flags.BUILD);
    }

[flint coyote]

Is there a way to disable this warning (in the serverlog)?

Loaded class <classpath> from <Plugin> v1.0.0 which is not a depend or softdepend of this plugin.

I'm trying to dynamically (based on a config) load classes from other plugins so I can not depend or softdepend on those plugins.

[lost matrix]

public Set<AbstractRegion> getIntersectingRegions(AbstractShape shape) {}

😄

[young knoll]

I approve

[lost matrix]

Why cant you softdepend on them then?

[flint coyote]

Because I will not know all of the plugins.
Basically I want to enable other developers to create plugins based on an interface that my plugin can use

[lost matrix]

RegisteredServiceProvider

[lost matrix]

Wait...

Why do you need to load their classes then?
Its their responsibility to add your plugin to their dependencies in this case.

Ok lets take a step back. To understand this correctly:

• You are defining an Interface
• Another plugin can implement this Interface
• You will use their implementation

[flint coyote]

I'm working on a Plugin to configure and run "Events" (basically just code) at certain times, in certain areas etc.

So basically any developer will be able to create an own event while depending on my plugin. But my plugin will have to instatiate those events with the right values (from it's configuration)

Therefore I need the classes of the other plugin. And I might need to have multiple instances of a class so handing me one instance would not be enough (unless I keep deepcopying it)

[kind hatch]

Oh, I think you have the same issue that PlaceholderAPI had.

[flint coyote]

Sounds about right that they would run into that aswell

[lost matrix]

This is commonly solved by using Factory classes.
And you need a system for others to register their factories.
This means you should not load anything from their plugin
but rather provide an API for registering their Factories.
They need to depend on your plugin.
So your plugin loads first.
Then their plugins load and register their factories.

[flint coyote]

Yeah that sounds possible. Might be able to create those Factories via Reflection aswell in order to keep the API as simple as possible.

Thanks, I'll figure something out based on the factory pattern

[pseudo hazel]

you wouldnt need reflection though

[lost matrix]

No reflections. You just let them create one instance of those Factories

[flint coyote]

But they'd have to implement an extra factory for each event (sure it wouldn't be much code) but the fields to configure in each event are already filled using annotations. So might aswell use those annotations for an automatically created factory

[lost matrix]

Sounds dirty and slow

[flint coyote]

Well that's what a lot of frameworks are based on. Spring Framework also adds Beans to classes via annotations

Therefore the implementation of an event is extremely simple

[ivory sleet]

Spring... hehe

[lost matrix]

You cant compare that because of multiple reasons.
First of all Spring is used in web environments where a few millis more or less dont matter.
In Spigot it does matter a lot. 10 Events á 2ms and you got almost 50% of your ticks time wasted with reflections.
Also Spring is a contained Framework. You have no idea what they do during compile time.

[lost matrix]

I hope you at least use a CDI framework like guice then

[flint coyote]

Well I can collect all the annotated variables during startup time and then I just set the values via reflection and don't have to fetch them each time.

I might think about skipping on reflection but the Factory-Method implementation increases the complexity for other devs

I'm not injecting depencies as in complex objects. I only inject simple values like Strings, ints that are read from a config

[lost matrix]

Meta programming via annotations is much more complicated and implicit than actually implementing a simple class
and calling registry.register(new CoolFactory())

But ok. You will find your way

[flint coyote]

Is that more complicated than creating a Factory for those 3 values?

I mean sure you have to know what an annotation is but besides that?

[pseudo hazel]

i would rather just implement an interface because its clear in what it does

but this seems just as good though

[lost matrix]

You would not create factories for those. This looks nothing like what you described...

[flint coyote]

Ok lets deep dive a bit then

[lost matrix]

And also: What if someone just wants to have other objects in there?
Do you have a dedicated Codec where they can register context resolvers?

[flint coyote]

They will get complex objects as configurationSections

Or MemorySection to be exact

[lost matrix]

[flint coyote]

Isn't it the same? Either I do the conversion by calling a context resolver or they do it themselves

But yeah to keep the "Eventpack" Plugins cleaner I might add that in aswell. Good point

[lost matrix]

If you are working with ConfigurationSections then you can just utilize
ConfigurationSerializable from Spigot

[kind hatch]

?paste those please

[undone axle]

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

[flint coyote]

So to kinda explain what I want to achieve:

We have this abstract class
https://paste.md-5.net/revacimisa.java
And for a command Block event I'd plan to implement it like this:
https://paste.md-5.net/peyeyagosa.java

The config would look kinda like this:

Events:
  commandblocker:
    engine_classpath: me.fabsi23.basicEventPack.events.restricting.BlockCommand
    engine_name: '&bCommand blocker'
    engine_description: 'Blocks commands'
    commandBlockedMessage: 'Command not allowed in this region'
    blockedCommands:
      - /tp

[tardy delta]

👀

[flint coyote]

That's the reason someone was added to the event, not a placeholder name

[lost matrix]

Im seeing a bunch of problems right from the get go

This alone is really dangerous

[tardy delta]

exposing players hehe

[flint coyote]

Because of the public getter or because Player objects can change?

[lost matrix]

Public getter

Also why are those abstract? Arent they supposed to mutate the participatingPlayers?

[young knoll]

Also player objects can change

[flint coyote]

No those are called and based on the return value it either adds the player to the event or does not

[young knoll]

If the player relogs

[flint coyote]

Players are removed from all events on logout

[tardy delta]

weak hashset kek

[young knoll]

Fair

I don't use anything weak because I am not weak

[tardy delta]

💪

[young knoll]

Is there a StrongHashSet or maybe an AlphaHashSet

[lost matrix]

SigmaHashSet

[pseudo hazel]

im more of an OmegaSet user myself

[lost matrix]

This is incredibly fragile design

[flint coyote]

So basically the event can decide whether a player can be added by entering a region while event is running.

The engine would try to add him but if the event says no it won't.
This is especially useful if you have to meet a goal before a timed event ends and the timer is about to run out

[lost matrix]

I can assure you that other devs will introduce massive problems here

[flint coyote]

I'm open for feedback since this is supposed to end up as an open api.

• I love to learn

And yes I will document all those methods and write guides obviously. It's just not done yet

[lost matrix]

Ok so step one would be: Rename your enums

[flint coyote]

Alright what names would recommend?

[tardy delta]

yes

[lost matrix]

AddReason RemoveReason etc

[tardy delta]

what

[lost matrix]

Next up: Find a way to strongly encapsulate your participatingPlayers.

No getter no setter

[flint coyote]

Wish it was kotlin and I could use internal lol

[tardy delta]

i saw students in my class not using access modifiers for collections at all 🥵

[lost matrix]

To be honest. I dont think this collection should be inside your event

Or at least not together with your abstract methods

[kind hatch]

Wdym? If you want to access a variable in another class, make a getter method. Doesn't matter if it's primitive or a "normal" object.

[jagged briar]

hi

[flint coyote]

Well I want it to be accessible inside the event. I might add it to the EventController where it's still accessible from inside the event

[lost matrix]

In what context do you use "Event" here?

[quaint mantle]

why cant i check this? it worked on another project on a dif java version. this one is java 8

[lost matrix]

?nohello

[undone axle]

https://nohello.net/en/

[flint coyote]

What do you mean?
It's basically all kinds of things.

Can be "spawn mobs" "tp player" "block command", "kick player" - any code, really

Wasn't sure what fits better/is more generic than "event"

[tardy delta]

show the declaration

[quaint mantle]

i know why nvm

[lost matrix]

And why does every event have participants?

[flint coyote]

Because it is regionbased. Not in the region = not participating.

Regions can be worlds, cuboids or spheres

[patent socket]

How can I make my while statement loop every 4 ticks until the statement inside is true? ```public class DialogueCommand implements CommandExecutor{
@Override
public boolean onCommand(CommandSender sender, Command command, String label, String [] args) {
if (args.length == 0 || args[0].length() > 0 && args[1].length() == 0) {
sender.sendMessage(ChatColor.RED.toString() + "You need to provide both a selector and text.");
return false;
} else {
Player player = Bukkit.getPlayerExact(args[0]);
int idx = 1;
String word = "";
int counter = 0;
while (counter < args[1].length()) {
word = word + args[1].charAt(idx);
player.spigot().sendMessage(ChatMessageType.ACTION_BAR, new TextComponent(word));
idx = idx + 1;
counter = counter + 1;
}
}

    return true;
}

}```

[kind hatch]

Use the bukkit scheduler.

?scheduling

[undone axle]

https://www.spigotmc.org/wiki/scheduler-programming/

https://www.spigotmc.org/wiki/scheduler-programming/

[lost matrix]

Ok but then those players should be inside the regions and not inside the events.
Or can one event be present in multiple regions?
This honestly looks like an implementation detail which should not be in the abstract class.

[flint coyote]

A region can have multiple events running but one event (instance) can only be in one region

But by being in the region you aren't forced to be in every event in that region

Could be that you reached the goal (e.g. find a certain block) and therefore you are removed from one event but are still in another (e.g. one that gives you a slowness effect or whatever)

[lost matrix]

My guy you need more classes

You are creating an uber class

[flint coyote]

It has 4 methods lol

everything else is up to the actual implementation of that class

[quaint mantle]

i lied, 1s

[lost matrix]

It tracks its participants, it listens to bukkit events, it provides registrations for itself
it contains all mutators and accessors.
This is an uber class

[quaint mantle]

the currentStats thing is:

    public HashMap<StatType, Double> currentStats = new HashMap<>();

thats it

but for some reason i cant check .containsKey since it wants an object and not StatType

[flint coyote]

Hmm. I can move the participants to the controller but I feel like the Listeners should be registered inside the event that is consuming them, no?

[lost matrix]

?paste

[undone axle]

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

[flint coyote]

The reason I put the players in there is that nothing would break if someone (for whatever reason) called removePlayer themselfes/actually removed a player. And to have one abstract "Api-Class". Basically to keep it as simple and quick to implement as possible.

[lost matrix]

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

I would start with this

Separate your configuration

[quaint mantle]

to clarify:
Here im checking some stuff etc.

for (ItemStack itemStack : stacksToCheck) {
                ItemBase.getStatsOfStack(itemStack).forEach((statType, aDouble) -> {
                    if(currentStats.containsKey(statType)) {
                        currentStats.merge(statType, aDouble, Double::sum);
                    } else {
                        currentStats.put(statType, baseStats.get(statType) + aDouble);
                    }
                });
            }

but it gives me this error

[flint coyote]

I can see where you are going with this. As in reusable configurations for multiple events

[quaint mantle]

the currentStats map is this

public HashMap<StatType, Double> currentStats = new HashMap<>();

[lost matrix]

If you are trying to simplify the API usage then you can not use those classes within your internals.
You might need to generate or create new Objects which can handle those simple implementations
in a more general and robust way.

[flint coyote]

Something like a "RunningEvent"-Class that holds an instance of "Event" and keeps the players within?

[lost matrix]

This would be something i could get behind.
When an event starts then you create an ActiveEvent which holds your general description of the Event functionality
and the participants.

[flint coyote]

I could delegate all calls from RunningEvent to the internal event.
Just like I did for the CompositeEvent.
https://paste.md-5.net/sududowawo.java

[lost matrix]

The only problem would be delegating or exposing participants to your Event implementations

Dont tell me EventController is a Singleton you use to manage your Events

[flint coyote]

I could create a copy of the list each time they query them. Or I just copy it once and if they mess with it in the wrong way it's their fault 😅

It's not a singleton but there is only one instance

Actually wait a sec let me push the whole project to a git repo. But it's not done yet so there's some things I still have to clean up

[lost matrix]

Im hungry and this system looks like it is written to mock SOLID in every way possible.

[flint coyote]

Well each region does have it's own Handler

But the EventController creates the regions and handlers (on startup) and keeps track of them (cleanup on shutdown etc)

[lost matrix]

Give the S and D a good look

[river oracle]

I always forget what solid is I just kinda code lmao

[flint coyote]

I'll do that and rethink the current structure I guess

[lost matrix]

Its a cool idea with the annotations and all but this will wreak havoc on devs and servers

[river oracle]

Also make sure you stick with naming conventions too this may have already been said thougj

[patent socket]

Ok so this is my code: ```public class DialogueCommand implements CommandExecutor{
@Override
public boolean onCommand(CommandSender sender, Command command, String label, String [] args) {
if (args.length == 0 || args[0].length() > 0 && args[1].length() == 0) {
sender.sendMessage(ChatColor.RED.toString() + "You need to provide both a selector and text.");
return false;
} else {
Player player = Bukkit.getPlayerExact(args[0]);
final int[] idx = {1};
final String[] word = {""};
final int[] counter = {0};
BukkitScheduler scheduler = Bukkit.getScheduler();
scheduler.runTaskTimer(plugin, () -> {
while (counter[0] != args[1].length()) {
word[0] = word[0] + args[1].charAt(idx[0]);
player.spigot().sendMessage(ChatMessageType.ACTION_BAR, new TextComponent(word[0]));
idx[0] = idx[0] + 1;
counter[0]++;
}
}, 4l, 4L
}

    return true;
}

}

class Other {
private final Dialogue plugin = Dialogue.getPlugin(Dialogue.class);
}```
And here are my errors:

[flint coyote]

Yeah I like the concept which is why I got behind this project.
I will definitly do some improvements before publishing it tho

[quaint mantle]

u forgot a )

at the end of the run task tmer

[flint coyote]

Especially chunk based region activation (for now all regions are active at once).
But I'll start with improving what you already mentioned!
Thanks a lot ❤️

[jagged briar]

we cant really help you from just that

well does the variable get edited at some point? where do you use it?

[olive sparrow]

Guys I'm at my wits end. What am I doing wrong ?

[kind hatch]

Are you trying to connect the torch to the block?

[olive sparrow]

Yeah. First to place cobble and then the torch and connect it to previous block.

[terse ore]

[kind hatch]

Use a WALL_TORCH and set the orientation using the BlockState

nope

[kind hatch]

Yes?

[rough drift]

That maps it to the nearest chat color

No it doesn't.

It returns the exact color

Maybe the bukkit one does

Because so far im using, to get the packet id while being registered, but what if i dont to oblise you to have an empty constructor. Cuz right now, if none default empty constructor while throw an InstantiationException

First if you want to learn how to code plugins, you should learn the lang where you coding
Not wondering to be rude ofc, just a recommendations of someone who have had bad experiences with it

[livid dove]

Hi there are plenty of great youtube channels out there to help

https://www.youtube.com/watch?v=eJkwnS5ZkAI This guys entire channel

[sterile token]

Totally agree with you

Its just people that just want things easy, and they expecting to code a bigger plugins in weeks without even knowing the lang where they coding

[livid dove]

yes

[rotund ravine]

Hello

[kindred valley]

That skin 🥴🥴

[rotund ravine]

Why is your head an old tv-screen

Wait what

How can you use a textured head on a blockdisplay

[rotund ravine]

Magic

[young knoll]

It only has nbt to store states

[tender shard]

my 16 inch laptop's screen's resolution is 44 times larger than the resolution of that pic lol

[echo basalt]

what's the res

[flint coyote]

I mean that was kinda the point

[tender shard]

3456x2234

[echo basalt]

ok

[young knoll]

Ah okay

[echo basalt]

bet you paid like 5 grand for it

[tender shard]

yeah but, 44 times is much more than I would have expected

[young knoll]

Item display not block display

[tender shard]

[echo basalt]

paid 1k for my 17" 2k 16:10 laptop

[sacred wyvern]

Is there a way to prevent a entity Villager from moving?

[tender shard]

remove their AI goals

[sacred wyvern]

Do you want an AI uprising?

🙂

[tender shard]

no, that's why we remove the goals 😛

[sacred wyvern]

Cheers

[tender shard]

requires NMS though

[young knoll]

setAi false

[tender shard]

that also prevents gravity etc

or being pushed by water or stuff like that

[echo basalt]

villagers are more complex than that

[young knoll]

Well gravity is moving

[echo basalt]

removing goals won't do much

they use the MemorySenses system

[tender shard]

I thought with moving, they meant the villager moving itself

[echo basalt]

I know

I tried

like

a year ago

[young knoll]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/entity/Mob.html#setAware(boolean)

Sets whether this mob is aware of its surroundings. Unaware mobs will still move if pushed, attacked, etc. but will not move or perform any actions on their own. Unaware mobs may also have other unspecified behaviours disabled, such as drowning.

[sacred wyvern]

That will work thank you

[tender shard]

ah nice, that looks useful

didnt know that existed

[young knoll]

Oh yeah custom crops with player heads and item displays

Now we are talking

[terse ore]

is there a way to fill an area of nether portals without them breaking?

            for (int x = 1; x < width - 1; x++) {
                System.out.println(block.getX() + x + " " + block.getY() + y + " " + block.getZ());
                block.getWorld().setType(block.getX() + x, block.getY() + y, block.getZ(), Material.NETHER_PORTAL);
            }
        }

mb guys

[young knoll]

Alright idk how interpolation on these things works

[kind hatch]

The display entities?

[young knoll]

Alright I got it

[sacred wyvern]

Does this require any special Mods the end player has to install? It looks like a new Subclass of entity called Mob

[young knoll]

no?

Represents a Mob. Mobs are living entities with simple AI.

[sacred wyvern]

Gotcha thank you. Was trying to find examples of spawning it. Found it on YouTube.

[kind hatch]

Hey @young knoll, do you know if the text display entities still use the ARGB color space for the background color?

[patent socket]

I already have this line in my onEnable() in Dialogue.jar. DialogueCommand.jar contains the files for the command: getCommand("dialogue").setExecutor(new DialogueCommand());

[young knoll]

yes

[hazy parrot]

,

[rough ibex]

put them in different files misread

[young knoll]

Class X implements A, B

[hazy parrot]

You can implement two interfaces, also there is TabExecutor which implements both

?

Oh it's Listener

[fluid river]

only in case you have

[hazy parrot]

I trough its CommandExecutor lol

[fluid river]

extends JavaPlugin implements Listener, CommandExecutor {}

[hazy parrot]

Forget about TabExecutor thingy then

[young knoll]

JavaPlugin already implements CommandExecutor

[young knoll]

It grow

[rotund ravine]

Cute

[onyx fjord]

nice

finally we will be able to grow weed

realistically

[young knoll]

The annoying part would be keeping track of them all, and ticking them

[onyx fjord]

u can tick those loaded

and unloaded keep track of unload time

[young knoll]

You could be jank about it and recreate vanilla ticking

[onyx fjord]

that too

[young knoll]

Pick 3 ranom blocks per loaded chunk every tick, and see if there is a itemdisplay with a certain tag on that block

Then grow it

[patent socket]

I have already, these are just the parts I don't know.

[eternal oxide]

its an entity? so grab all entities in the chunk on chunk load

[young knoll]

Yeah

[patent socket]

Yeah I did this and it didn't work. I don't know if you would like me to put it in the Dialogue.jar or the DialogueCommand.jar.

[young knoll]

Grab them on load and load them into a map of some kind

[undone axle]

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

[eternal oxide]

entities will not be loaded when the chunk loads, so delay your search

[young knoll]

Right right

There is a new event for that

Is this the right way to spawn a mob?

        try {
            this.entity = this.location.getWorld().spawn(this.location, Mob.class);
        } catch( IllegalArgumentException e ) {
            LOG(LogType.Info, e.getMessage());
        }

I keep getting

IllegalArgumentException: Cannot spawn an entity for org.bukkit.entity.Mob

This is almost similar to the spawnEntity command which worked for a regular villager.

[olive sparrow]

Guys am I doing this directional wrong. Could you point me in the right direction please ?

[static ingot]

You can't spawn a mob, you need to spawn a subclass of mob that actually represents a specific entity in-game

[onyx fjord]

U can cast directly in the if statement

[sacred wyvern]

Gotcha thank you

[olive sparrow]

Hmm no luck there

[echo basalt]

Yeah wall torch.

[echo basalt]

It's directional for sure

[young knoll]

Torch is always on the ground

Rotating one torch got me stuck for couple of hours lol 😄

[young knoll]

Wall torch is the one that can be rotated

[hybrid spoke]

e.setCancelled(true)

[weak meteor]

i have it in the second line

[pseudo hazel]

cancelling the inventory event outright prevents you from moving any items in the whole inventory

you need to only cancel it if the player tries to move items that shouldnt be able to be picked up

[weak meteor]

damn

but if (inventoryView.getTitle().equals("Main Menu"))

isnt preventing cancelling the normal inventory?

[pseudo hazel]

thats the whole view

the player inventory is always part of the same view

[weak meteor]

Hmm

[pseudo hazel]

you need to check the slot numbers

[weak meteor]

so can i change it so i can move in my inv but not in the artificial inv

[pseudo hazel]

yes

cancel it if the slit number is invalid

[weak meteor]

Wdym

[young knoll]

You can check if the clicked inventory equals the top inventory

Or the bottom inventory

[weak meteor]

How to?

[pseudo hazel]

probably some method

of the event

[young knoll]

event.getClickedInventory.equals(view.getTopInventory())

Iirc

[weak meteor]

if (e.getClickedInventory().equals(inventoryView.getTopInventory()))

okay

ill try

Thanks, it worked.

Is there any other type of passing enchants from a book to a item other than: ```java

                        ItemMeta bookMeta = book.getItemMeta();

                        Map< Enchantment, Integer> enchants = bookMeta.getEnchants();
                        for (Map.Entry<Enchantment, Integer> entry : enchants.entrySet()){
                            Enchantment enchantment = entry.getKey();
                            int level = entry.getValue();
                            swordMeta.addEnchant(enchantment, level, false);
                        }

You have to check only for top inventory, because if you use getClickedInventory() will return the inventory you are clicking

Nope.

Unless the getAddress() provided there would be the host, but I doubt that.

[modest tartan]

Could anybody provide an example of how to set the transition of a block display so that the block is just rotated 45 degrees or standing on one corner? I've been goofing off with the numbers in the setTransformation method the entity goes somewhere in my world and I've tried teleporting to it but I don't see the entity. Heres the code I'm currently using.

public void omPlace(BlockPlaceEvent event) {
        event.setCancelled(true);
        BlockDisplay nameTag = (BlockDisplay) event.getPlayer().getWorld().spawnEntity(event.getBlock().getLocation(), EntityType.BLOCK_DISPLAY);
        nameTag.setBlock(event.getBlock().getBlockData());
        nameTag.setDisplayWidth(1);
        nameTag.setDisplayHeight(1);
        nameTag.setTransformation(new Transformation(new Vector3f(0, 2, 0), new AxisAngle4f(45, 0, 2, 0), new Vector3f(0, 1, 0), new AxisAngle4f(12, 9, 3, 4)));
        nameTag.setInterpolationDelay(0);
    }```

Idk what AxisAngle4f or Vector3f really is either so the numbers I'm using are just to fill the requirements

I figured I'd learn what they are once I filled them in and saw the effect but my effect is no entity display lmao

[young knoll]

Vector3f is just a vector

X Y Z

[modest tartan]

Yeah I noticed that

[young knoll]

The other one is a quaternion

[modest tartan]

Its optionally AxisAngle4f I think

No

hmmm

[brave sparrow]

it's not immutable but you can't get a mutable copy of an item in an inventory

you make a copy of it, modify the copy, and set it back into the slot

[young knoll]

Items in hand are mutable tho
