since technically the main command is just a single command 😛

Well yeah, but forget abt that lol.

Probably startup

Idk how trying to create a world at shutdown would go

young knoll Idk how trying to create a world at shutdown would go

true

young knoll Jul 31, 2023, 12:24 AM

#

Generally one per command

#

All the main class has to do is setExecutor

wet breach Jul 31, 2023, 12:26 AM

#

this is how I usually do my commands. I only have main commands where it makes sense, and then anything fitting in those main commands are sub commands

is it generally better to use color codes rather than ChatColor?

young knoll Jul 31, 2023, 12:27 AM

#

No

#

ChatColor is meant to abstract magic values

wet breach Jul 31, 2023, 12:27 AM

#

but magic values are fun 🙂

young knoll Jul 31, 2023, 12:27 AM

I'm not able to get NMS to work. I ran buildtools and copied the exact pom <plugin> and <dependency> the NMS tutorial showed, but when I put the dependency in my pom.xml, it compiles with an error telling me

On start can easily be done by a plugin and you can even roll back to a certain state if you saved it (even for the main world)

With the Mojang remapped version you do use :jar: iirc

It’s hard to say what you require for X players

2 cores isn’t a lot though

i think you'll be fine. you might have some hiccups along the way. mine runs fairly well.

#

less

#

6gb of ram, 2 cores. but I have like 30 people instead. I have my world size capped to help as well.

#

maybe not as many plugins as you, but there are a lot.

young knoll Jul 31, 2023, 12:41 AM

#

Plugin count doesn’t mean much

#

You could have 100 plugins that do basically nothing

#

Or 5 that are very heavy

#

?

#

Paper/spigot are apis

zenith gate Jul 31, 2023, 12:45 AM

#

they are APIs

young knoll Jul 31, 2023, 12:45 AM

#

If you use the paper api you have to use a paper server

#

If you use the spigot api you can use spigot or paper

zenith gate Jul 31, 2023, 12:45 AM

#

You can also use spigot plugins on paper server.

I tried unloading the gameworld, but its literally just not continuing beyond Bukkit.unloadWorld(worldName, false);

#

There are no players on the world

wet breach Jul 31, 2023, 12:46 AM

#

did you unload all the chunks?

young knoll Jul 31, 2023, 12:47 AM

#

^ you should do that first as well

#

Even then I believe unloadWorld may not be instant

#

Not sure

rain night Jul 31, 2023, 12:48 AM

#

wet breach did you unload all the chunks?

Like that?

World world = Bukkit.getWorld(worldName);
            if (world == null) continue;
            for (Chunk chunk : world.getLoadedChunks()) {
                chunk.unload();

why would you continue if world is null?

rain night Jul 31, 2023, 12:52 AM

its not returning

wet breach Jul 31, 2023, 12:52 AM

#

typically wouldn't want to continue if that condition is met, you would want to break out of the loop

#

what is the purpose of the int? lol

#

this code is more better to use btw

#

just not sure of the int there is all

rain night Jul 31, 2023, 12:54 AM

wet breach typically wouldn't want to continue if that condition is met, you would want to ...

Should continue with the next world tho

wet breach Jul 31, 2023, 12:54 AM

#

well as we stated you can't unload the main worlds

rain night Jul 31, 2023, 12:55 AM

#

im not

wet breach Jul 31, 2023, 12:55 AM

#

so you have multiple worlds needing to be unloaded?

#

o.O

#

thought it was just a single world lol

rain night Jul 31, 2023, 12:55 AM

#

Its actually currently only one world, but could handle multiple

wet breach Jul 31, 2023, 12:56 AM

#

yeah but if we unloading chunks because we want to unload the world, not sure why we care how many are unloaded?

#

as I said was just curious more then anything lmao

young knoll Jul 31, 2023, 12:57 AM

they clarified on it was for multiple worlds, where as I was under the impression for a single world. In which case if the world is null you wouldn't want to continue

it doesnt even seem like its unloading any chunks.. https://paste.md-5.net/ixemohotog.cs

Then i could also jsut delete the files

flint coyote Jul 31, 2023, 1:08 AM

I think he wants to create a new world without restarting the server

rain night Jul 31, 2023, 1:08 AM

This Bukkit.unloadWorld(worldName, false) doesnt returns. Therefore nothing behind it in the code is getting executed

young knoll Jul 31, 2023, 1:08 AM

Probably no easy way to find out sadly

rain night Jul 31, 2023, 1:09 AM

Actually not. I just want to delete the world. I was told that i have to unload it first.

young knoll I’m curious what it gets stuck on

same

young knoll Jul 31, 2023, 1:09 AM

You’d have to attach a remote debugger

flint coyote Jul 31, 2023, 1:09 AM

#

Is restarting the server an option? Or does that take too long?

rain night Jul 31, 2023, 1:10 AM

#

Im shuting down the server after deleting the world, if the function would return anything

flint coyote Jul 31, 2023, 1:10 AM

#

Why don't you delete the world on startup?

#

Wouldn't have to deal with unloading then

rain night Jul 31, 2023, 1:10 AM

Thats true...

zenith gate Jul 31, 2023, 1:10 AM

Set the plugin to run before world loading using the plugin.yml

WAIT!!!

flint coyote Jul 31, 2023, 1:12 AM

young knoll Jul 31, 2023, 1:12 AM

#

Turns out that’s a bit misleading

#

It controls when the plugin enables, not when it loads

rain night Jul 31, 2023, 1:13 AM

#

Maybe the world is getting unloaded beforehand so there is nothing to unload. Also the unloading of chunks hasnt worked. Is there a way to check if a world is loaded?

peak storm Any advice I have been stuck on this all weekend

You could try unloading the world in onDisable to prevent the server autosaving it. If it's the main world you are probably out of luck on that route.

#

Dunno if the main world can be unloaded in onDisable but I doubt it

peak storm Jul 31, 2023, 1:42 AM

#

flint coyote You could try unloading the world in onDisable to prevent the server autosaving ...

I'm unloading the arena world when the game ends

unkempt peak Jul 31, 2023, 1:42 AM

#

Does player#sendBlockChange cause a block update on the cleint?

peak storm Jul 31, 2023, 1:42 AM

#

You can see the code here

#

unkempt peak Does player#sendBlockChange cause a block update on the cleint?

Yes, but it's only for the client. The server will not see that change.

flint coyote Jul 31, 2023, 1:43 AM

#

Is that unloading and then loading it again?

#

I thought you restarted in between

#

Because in that case the restart save obviously isn't the problem

peak storm Jul 31, 2023, 1:43 AM

#

flint coyote Is that unloading and then loading it again?

No this is done after the game ends

#

Then once the loading is done the map can be played again

flint coyote Jul 31, 2023, 1:44 AM

#

So no restarts

peak storm Jul 31, 2023, 1:44 AM

#

nope

flint coyote Jul 31, 2023, 1:44 AM

#

Alright

peak storm Jul 31, 2023, 1:44 AM

#

How it works it should work we no server restarts

flint coyote Jul 31, 2023, 1:45 AM

#

I mean I would know a workaround but there has to be a better way

#

So you tried the listener, too?

peak storm Jul 31, 2023, 1:45 AM

#

yup

#

flint coyote Jul 31, 2023, 1:45 AM

#

Does it fire?

#

Just to make sure it's registered

peak storm Jul 31, 2023, 1:46 AM

#

I can check

quaint mantle Jul 31, 2023, 1:46 AM

#

i add my command to pluginyml

#

why i got this ?

#

ah wait

flint coyote Jul 31, 2023, 1:47 AM

#

This warning does not correlate to your plugin.yml

#

The IDE does not check your plugin.yml in order to fire code-related warnings

young knoll Jul 31, 2023, 1:49 AM

#

You can just suppress it

#

Or add a requireNonNull

#

To appease the ide overlords

rain night Jul 31, 2023, 1:50 AM

#

Okay Fabsi...

#

It kinda works

flint coyote Jul 31, 2023, 1:50 AM

#

Alright, what's not working then?

rain night Jul 31, 2023, 1:51 AM

#

BUT it takes ages to join the world

quaint mantle Jul 31, 2023, 1:51 AM

#

i got this why ?

#

young knoll Jul 31, 2023, 1:51 AM

#

Yeah making a world isn’t exactly fast

peak storm Jul 31, 2023, 1:51 AM

#

flint coyote Alright, what's not working then?

rain night Jul 31, 2023, 1:51 AM

#

Is there a way to preload a world?

flint coyote Jul 31, 2023, 1:51 AM

#

rain night Is there a way to preload a world?

sadly no

rain night Jul 31, 2023, 1:51 AM

#

shit

young knoll Jul 31, 2023, 1:52 AM

#

Not unless you have a copy of the premade world somewhere

flint coyote Jul 31, 2023, 1:52 AM

#

And can't be done asynchronous either

rain night Jul 31, 2023, 1:52 AM

#

Oh no

rain night Jul 31, 2023, 1:52 AM

#

young knoll Not unless you have a copy of the premade world somewhere

Its a random world..

young knoll Jul 31, 2023, 1:52 AM

#

Yeah then no

#

You need a server to generate it

flint coyote Jul 31, 2023, 1:53 AM

#

You could go overkill.
Have another server create the world for you and transfer the files.
You would still have to load it which does cause lag though

rain night Jul 31, 2023, 1:53 AM

#

flint coyote You could go overkill. Have another server create the world for you and transfer...

Seems like a normalw workaround hahah

flint coyote Jul 31, 2023, 1:53 AM

#

Definitly not normal in terms of resources used xD

#

So the current problem is that the world generation takes too long?

rain night Jul 31, 2023, 1:54 AM

#

But i could await the world loading... Is it the WorldLoadEvent?

rain night Jul 31, 2023, 1:54 AM

#

flint coyote So the current problem is that the world generation takes too long?

Countdown starts in loadscreen.. So yeah

flint coyote Jul 31, 2023, 1:55 AM

#

Countdown of?

#

Aren't you restarting the server? Your plugin should not load before the world got fully generated and loaded

#

The countdown one I mean

rain night Jul 31, 2023, 1:55 AM

#

Its a little game im doing for friends, we spawn in a new world and can move after 5seconds

flint coyote Jul 31, 2023, 1:56 AM

#

Yeah then either start the countdown on WorldLoadEvent or even better: PlayerJoinEvent

rain night Jul 31, 2023, 1:56 AM

#

Nah bro... When i teleport the players to "world" the loading screen is taking ages

flint coyote Jul 31, 2023, 1:57 AM

#

peak storm

Hmm I don't know about more methods of denying save either

flint coyote Jul 31, 2023, 1:57 AM

#

rain night Nah bro... When i teleport the players to "world" the loading screen is taking ...

Oh that's probably because you are teleporting them to unloaded chunks that then have to be generated

#

Preload them

rain night Jul 31, 2023, 1:57 AM

#

YES

#

I WANT TO DO THAT 🙂

#

But how??

flint coyote Jul 31, 2023, 2:01 AM

You are accessing index 1 when your size is 1

Therefore the maximum index you can access is 0

#

Ignore me

flint coyote Jul 31, 2023, 2:02 AM

But since it says "for length 1" it should be 1

young knoll Jul 31, 2023, 2:02 AM

Yes a size of 1 does not mean array[1] exists

Since array indexes start at 0

How would you do the awaiting of the level loading? WorldLoadEvent isnt the way to go i think, because it seems like its firing on inital load only

flint coyote Jul 31, 2023, 2:22 AM

#

The world loading or the chunk loading?

rain night Jul 31, 2023, 2:23 AM

#

I think its the chunks....

#

Or can i just preload the chunks with the range of the render distance?

flint coyote Jul 31, 2023, 2:24 AM

#

Just load them before teleportation. Chunk loading is blocking

rain night Jul 31, 2023, 2:25 AM

#

flint coyote Just load them before teleportation. Chunk loading is blocking

Do you know how i can read the chunk render distance ?

flint coyote Jul 31, 2023, 2:27 AM

#

Would have to check the docs aswell

#

But you don't have to load all chunks. Just load a 3x3 and then tp

#

the rest will load in those few seconds or until you leave the 3x3

rain night Jul 31, 2023, 2:28 AM

#

I'll do that

flint coyote Jul 31, 2023, 2:28 AM

Unless it's important to instantly have full view on the map after teleportation

Hey so I have been trying to optimize changing large amounts of blocks and have run into alot of trouble. I tried using nms because people have said it's alot faster than setType so I tried using the PacketPlayOutBlockChange to send a block change to the player but it is significantly slower than setType and even overwhelms the cleint after a while forcing the client to time out. After looking through nms code I found PacketPlayOutMultiBlockChange but I have no idea how it works. Could I somehow use that to send an entire batch of block changes at once and would it be faster than the other methods?

#

For context I'm working on a video player project and need to optimize 1.1m block changes per second

#

I also can't seem to figure out how to stop block and lightning updates from happening

chrome beacon Jul 31, 2023, 4:29 AM

#

Paper has api for the multiblock change and Spigot has API for block change

#

You don't need to touch the packets manually

unkempt peak Jul 31, 2023, 4:30 AM

I know about Player#sendBlockChange but won't that effectively do the same thing?

chrome beacon Jul 31, 2023, 4:30 AM

Yes but without the nms

Essentially yes but I need it to be as optimized as possible. setType isn't fast enough

How would I update the player after using something like method 2?

There is an nms method in the nms world class that can update blocks, if you don't want reinvent the wheel: https://github.com/TheGaming999/BlockChanger

setSectionBlock is for the third method, setChunkBlock for the second

Idk @lean widget gave me the github

they made it

tender shard Jul 31, 2023, 6:00 AM

#

ah ok. yeah it uses hardcoded "obfuscated" method and field names so it'll only work on one specific 1.19 version. the proper way would be to use mojang maps, then you have the same code for all versions, and then run it through the maven specialsource plugin with the respective mappings for the version you want it to work on

#

basically, these two blog posts are about using mojang maps + how to switch from obfuscated/spigot mappings to mojang maps:

Yes, players cant have null in their main hand. Only in the offhand.
If a player holds nothing then he actually has air in his hand.

It I put air in the offhand using the replaceitem command or using my plugin will it return air then?

quaint mantle so only check air?

And while you are at it: Make it a utility method:

public static void dropHandItem(Player player) {

}

And if you want to make this even more useful you can implement it
for everything a player can hold:

public static void dropItem(Player player, EquipmentSlot slot) {

}

Will teach you a bit.

I got another problem and maybe you guys can see it. I created a command called WorldTeleporter and it basicly loops through all worlds on the server, sets it on a menu and the player can click on the items to teleport to the world. For example if i have a world in my server folder called "World_end" it will see the folder, create a grass_block called "world_end" and if the person clicks on it, the plugin will read out the name of the block (in this case "world_end") and teleport the player too it. But for some reason i got 10 worlds and all worlds work correctly except one. This world generates a NULL error and it says

[13:21:33 ERROR]: Could not pass event InventoryClickEvent to VTDPlugin v1.0-SNAPSHOT

Inside your world folder there is a file which stores the UUID of the world.
If you use a world as template you need to remove this UUID file from it.

Because two worlds with e same UUID won't work

I see the problem. You are probably not checking if the chunk you are trying to spawn an entity in is loaded.
If you try to spawn an entity at an unloaded position then the chunk gets loaded first. This can be very expensive.

Just like I said, this only differs in the location and the mob

this is the only thing I can think of that causes all that lag

lost matrix Jul 31, 2023, 1:48 PM

If you see yourself copy/pasting code then its time to take a step back and write something that can be
applied to all 3 cases with just one method.
Otherwise you going to have to fix the same code 3 times if you see a problem or want to make a change.

#

Anyways all of those tasks produce lag in the same way i described.

#

All 3 produce lag

upbeat fog Jul 31, 2023, 1:49 PM

I'll fix them first and maybe increse the spawn time and lower the mob cap

lost matrix Jul 31, 2023, 1:49 PM

How about you dont spawn mobs in unloaded chunks?

lost matrix How about you dont spawn mobs in unloaded chunks?

Yeah, that's what I was thinking.

lost matrix Jul 31, 2023, 1:51 PM

Youll figure it out. Spawning mobs is a pretty hard task to get right.
And keeping track of mobs is as well.

upbeat fog Jul 31, 2023, 1:52 PM

#

Yes I've noticed that. Before this one I was using an armor stand to spawn the mobs, and used an int to keep track of them 💀

lost matrix Jul 31, 2023, 1:52 PM

Using a scheduler is also a very questionable approach

upbeat fog Jul 31, 2023, 1:53 PM

What would you use to spawn custom mobs and keep track of them?

lost matrix Jul 31, 2023, 1:53 PM

Events to keep track and scheduling to spawn

tame wolf Jul 31, 2023, 1:54 PM

#

You could use NBT data to keep track of them no?

upbeat fog Jul 31, 2023, 1:54 PM

All I need is the amount of mobs alive.

Not really

chrome beacon Jul 31, 2023, 1:59 PM

#

ah yes manual method obfuscation 💀

#

Your method names are a b and c

#

That's not how you're supposed to name things

#

Also when spawning an entity and you'd like to modify it you should use the spawn method that takes a consumer

#

This will ensure the entity is modified before it's spawned

lost matrix Jul 31, 2023, 2:24 PM

#

sterile breach But if i need to keep the old instance ?

A gui is just a view of data. You should be able to view this data with a new instance without any problems.
So there is no need to keep an instance. But you can design a system to keep track of nested guis if you want.
There is an endless amount of approaches to this.

Yes but if i have a page system i need to keep the var index.

lost matrix Jul 31, 2023, 2:26 PM

#

sterile breach Yes but if i have a page system i need to keep the var index.

Then implement the decorate method in a way that incorporates this index.

#

This way you dont have to open a new inventory. Simply use the same inventory and update the icons.

sterile breach Jul 31, 2023, 2:26 PM

#

The index is in the old instance

echo basalt Jul 31, 2023, 2:27 PM

#

are you opening a new gui for each page?

lost matrix Jul 31, 2023, 2:27 PM

#

I dont know what you are doing... pass the index to the "new" instance then?
Why do you need multiple instances for pagination?

#

Just use one Inventory and re-decorate it.

sterile breach Jul 31, 2023, 2:28 PM

#

echo basalt are you opening a new gui for each page?

I haven't done the system yet, but I think I will, because I prefer to do it myself. It avoids the player to see the items changing little by little.

echo basalt Jul 31, 2023, 2:28 PM

#

little by little

#

hah

sterile breach Jul 31, 2023, 2:28 PM

yes, but when I click on a new page, I open a new inventory.

echo basalt Jul 31, 2023, 2:28 PM

What will happen in reality is that your cursor keeps resetting to the middle and the screen flashes for each page

#

which is very annoying

sterile breach Jul 31, 2023, 2:29 PM

#

its true

echo basalt Jul 31, 2023, 2:29 PM

#

If you're really concerned about items refreshing little by little just populate the item array instead

sterile breach Jul 31, 2023, 2:29 PM

#

you have reason

echo basalt Jul 31, 2023, 2:29 PM

#

But you shouldn't need to because bukkit doesn't send a packet for each setItem call iirc, just marks it as dirty and updates it at the end of the tick

Not much you can do to fix that. It's up to md and Bungee contributors to update dependencies

Keep your project up to date with the latest dependencies. Not much more you can do.

Just run mvn install on your other project.
This way its installed in your local maven repo and you can use
