i return a custom variable using a getter and modifing it like this, the main variable gets modified too?

List<Gang> gangs = new ArrayList ...

public static List<Gang> getGangs() {
  return gangs;
}

public static Gang getGang(String name) {
  for (Gang gang : getGangs()) if (gang.getName().equals(name)) return gang;
  return null;
}

Gang test = getGang("someGangWhichExistsAndItsNotNull");
test.setName("newName");

#

is the name of the gang from gangs array list gets updated?

young knoll Sep 22, 2023, 3:42 PM

#

Yes

#

Also if you want to get the gang by name, use a map

sage patio Sep 22, 2023, 3:43 PM

#

what is the gangs are final?

#

private static final List<Gang> gangs = new ArrayList<>();

young knoll Sep 22, 2023, 3:44 PM

#

They will still change

#

That makes the list final, not the contents of it

sage patio Sep 22, 2023, 3:44 PM

#

and if that Gang changes somewhere else, the test gets updated too?

young knoll Sep 22, 2023, 3:45 PM

#

Most likley, yes

#

Everything is just a refrence to the actual gang object stored somewhere in memory

what about you?

#

do you shade the Citizens into your plugin?

timid hedge Sep 22, 2023, 3:53 PM

#

No, i dont know how to. Can you show me?

sage patio Sep 22, 2023, 3:53 PM

#

how much is the size of your plugins .jar file?

young knoll Sep 22, 2023, 3:54 PM

#

You shouldn't shade citizens

#

It's meant to be run standalone

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.

#

EntityInsentient (and derivate types) should have a setPersistenceRequired() method

#

Not really sure why you're using NMS for this though

#

That'd be because armour stands are not EntityInsentients

#

So ArmorStand#setRemoveWhenFarAway() doesn't work either

#

Because we have no direct mapping to EntityInsentient, so it's on LivingEntity instead

#

In reality it does nothing for non-insentients

as far as i know, you can't give ai to armor stands without serious work

young knoll Sep 22, 2023, 4:54 PM

#

Nah the event is probably the best way

lilac dagger Sep 22, 2023, 4:55 PM

#

but if the chunks get unloaded then that's the best way

young knoll Sep 22, 2023, 4:56 PM

#

I mean

#

You could make a custom NMS entity that doesn't get saved

#

But yknow, that's just a mess of NMS

Then request it be exposed by the API

and they don't provide getts and setters

you can do so?

the playerconnection shouldn't be private

or at least a getter

you 1st need to learn java, and make ur variable Player and make it the result of Bukkit.getPlayer(args[0])

Download and read mappings in your plugin

its why the mojmap server isnt designed for prod servers

lilac dagger Sep 22, 2023, 5:23 PM

#

well, it does make sense

young knoll Sep 22, 2023, 5:24 PM

Like libraries but mappings

hiya, when i have a basic command made, how do i change the default permissions of it?
so like lets say i want a command thatd be allowed to be used by all players, but lets say an admin decided to make it not allowed for all with luckperms for example , they could change it.
my problem is, that when i add player.haspermission, then the permission will be false by default unless the player has op. how do i make the permission true?

I ran buildtools and selected the new jar file: "Spigot\Spigot-API\target\spigot-api-1.20.1-R0.1-SNAPSHOT-shaded.jar"
But its not working (error at every org.bukkit import) , if i switch back to "Spigot\Spigot-API\target\spigot-api-1.19.2-R0.1-SNAPSHOT-shaded.jar" everything is working fine.
Can anyone tell me what im missing?

young knoll Add the perm in your plugin.yml

this should work right? the names are obv placeholders but if i just set the permissions correctly it will work?

Bootstrap Jar
The main spigot-1.18.jar is now a bootstrap jar which contains all libraries. You cannot directly depend on this jar. You should depend on Spigot/Spigot-API/target/spigot-api-1.18-R0.1-SNAPSHOT-shaded.jar, or the entire contents of the bundler directory from your server, or use a dependency manager such as Maven or Gradle to handle this automatically.

Please read the release notes for further information: https://www.spigotmc.org/threads/9-years-of-spigotmc-spigot-bungeecord-1-18-1-18-1-release.534760/#post-4305163

not all lists are backed by an array either, fwiw; and even if they are, they array length might be larger than the list size etc

Are you running your DB query on the main thread?

lime moat Sep 22, 2023, 7:08 PM

#

I believe so

zealous osprey Sep 22, 2023, 7:10 PM

#

Queries to a DB should (almost?) always be run on a seperate thread, otherwise the server has too wait for a response before continueing to the next game tick.
And for such Multi-threaded applications you can use something called a CompleteableFuture. This is an object which will run some code, after some async task has been completed.

zealous osprey Sep 22, 2023, 7:15 PM

#

So:

I'd recommend to try and untangle your onEnable method. You have alot in there; Mainly creating seperate classes for your command logic.
Then, as I suspected, you are running your DB in the same thread as your normal code. Use the Scheduler from the spigot API to run the DB queries in a seperate thread. As I mentioned, you should then use CompleteableFuture too handle data coming from your DB and what should be done with it.

public CompletableFuture<Boolean> isPlayerRegistered(final OfflinePlayer player) {
    final CompletableFuture<Boolean> complete = new CompletableFuture<>();

     plugin.getServer().getScheduler().runTaskAsynchronously(plugin, () -> {
            boolean exists = false;
            try (Connection con = this.connectionPool.getConnection()) {
                PreparedStatement pstmt = con.prepareStatement("SELECT DiscordId FROM staff WHERE DisplayName=?");
                pstmt.setString(1, player.getName());
                ResultSet rs = pstmt.executeQuery();
                exists  = rs.next();
                pstmt.close();
                rs.close();
                con.close();
            }
        } catch (SQLException var9) {
            // handle error
        }

        complete.complete(exists);
     });

  return complete;
}

Something like this ig

You could also create a ConcurrentLinkedList and cache incoming query requests and then have just a single thread for querying, instead of creating a new one every time you query something.

Btw, what do you think is the preferable approach too querying?
Caching queries and then getting them from a queue; So you only have one seperate thread for interacting with the DB
OR
Just using the scheduler too create a new task every time you query from the DB?

It uses a thread pool

zealous osprey Sep 22, 2023, 7:37 PM

#

So you let the query block the main thread while the DB responds?
Or is there a way too not do that in a single threaded app?

slender elbow Sep 22, 2023, 7:37 PM

#

single thread doesn't necessarily mean the server thread

you just run the queries in a single thread, just, separate, but it's its own

Hey there, i want to know are there any ways to place a lot of blocks using 1.8 without getting lighting issues? sometimes it makes some very dark places which will be fixed by placing a block, but it takes a lot of time in order to manually place/break blocks around in order to get it fixed. i tried getting far away from it, but the lighting issue remains.
(Again, its 1.8 and yea, Its up to you for the answer, thanks!)

very unspecific.
What data do you WANT and NEED to save? How do these relate, etc.

short pilot Sep 22, 2023, 8:14 PM

#

ooh good question! Let me write it down real quick

#

The plugin I'm aiming to develop is a factions-esque type, just out of self interest. I have my objects made and commands work in the test server, but naturally nothing saves to file yet. The questions I have follow:

How can I implement saving to file, and what is the best practice to?

Should data be saved at regular intervals for a "faction" and then loaded in on plugin start?

For more large amounts of data such as chunks claimed for a "faction", should this be saved somewhere else other than the main faction file?

Finally, for each player, should I only save their data on logout or at certain intervals?

I really appreciate the help, thanks!

zealous osprey Sep 22, 2023, 8:19 PM

#

You will almost always have to load some data into your plugin when starting it.
You could save some data in regular interavals, will surely be benefitial if the server ever crashes unexpectedly.
Saving and writing data is fine, aslong as you don't save and load multiple times a second. Then I would recommend caching the data temporarily and creating regular backups/updates.
I would save player data, factions data (including their settings) and claimed chunks in seperate files/tables and identify them via a certain ID.

Any objections from someone?

maybe it was like 'if this exists'

#

iunno

#

uuuh did i mess up my reflection?
java.lang.NoSuchMethodException: net.minecraft.server.level.EntityPlayer.attack(net.minecraft.world.entity.Entity)

#

the craftbukkit project says the method exists

it's the md mapping

#

mojmap has it as Player and ServerPlayer

smoky oak Sep 22, 2023, 9:28 PM

#

...sooo?

#

i do not recall that the mappings matter after building

#

is this because im using reflection?

#

?mappings

undone axleBOT Sep 22, 2023, 9:29 PM

#

Compare different mappings with this website: https://mappings.cephx.dev

smoky oak Sep 22, 2023, 9:31 PM

#

and how do i call a spigot method using reflection then?

#

also it's saying its not finding the method, not that its not finding the class

rough harness Sep 22, 2023, 9:34 PM

#

any one know A claim plug in that works multiverse that can be per world

smoky oak Sep 22, 2023, 9:36 PM

#

side note, I'm using the getHandle method, iirc that spits back out the md5 mappings

rough harness Sep 22, 2023, 9:36 PM

#

ok

smoky oak Sep 22, 2023, 9:39 PM

#

Bukkit.broadcastMessage("Player class: "+ nmsPlayer.getClass().getName()); -> net.minecraft.server.level.EntityPlayer

i think i found the issue

#

can i somehow get the spigot EntityPlayer class without the monajg obfuscated methods?

young knoll Sep 22, 2023, 9:45 PM

#

wut

echo basalt Sep 22, 2023, 9:45 PM

#

you're running a remapped server

#

somehow

smoky oak Sep 22, 2023, 9:45 PM

#

say what now

#

is this a result of using --remapped with buildtools to get the remapped jars in .m2?

remote swallow Sep 22, 2023, 9:48 PM

#

are you also running that jar as the server jar

smoky oak Sep 22, 2023, 9:48 PM

#

yes? i wasnt aware it was an issue

#

why should i build twice

#

im just running buildtools --rev latest right now

#

if that fixes it thanks illusion, i would have NEVER figured that out

#

annoying that buildtools is so slow tho

young knoll Sep 22, 2023, 9:50 PM

#

The jar you get from buildtools is always the obfuscated one

smoky oak Sep 22, 2023, 9:51 PM

#

youre saying thats not the issue?

smoky oak Sep 22, 2023, 9:52 PM

#

smoky oak im just running buildtools --rev latest right now

Success! Everything completed successfully. Copying final .jar files now.
Copying spigot-1.20.1-R0.1-SNAPSHOT-bootstrap.jar to D:\Creation\Minecraft\.\spigot-1.20.1.jar
  - Saved as .\spigot-1.20.1.jar

Okay why is latest still 1.20.1 instead of 1.20.2?

young knoll Sep 22, 2023, 9:53 PM

#

Because latest is latest stable

smoky oak Sep 22, 2023, 9:53 PM

#

ah i see

#

anyways ive rebulit with no args except --latest, so lets see if that helped. you said it wont, illusion said i fucked up my pc

remote swallow Sep 22, 2023, 9:55 PM

#

yep pc dead

#

throw it away

smoky oak Sep 22, 2023, 9:55 PM

#

echo basalt you're running a remapped server

how do i fix this? its still spitting out the obfuscated methods after using a server jar that resulted from just using --latest

#

I'd like to use the md mappings because they're so stable and cannot understand why it would return those methods

#

getMethods and getDeclaredMethods return completely different sets of methods but neither is the set of methods i want urgh

young knoll Sep 22, 2023, 9:58 PM

#

wut

smoky oak Sep 22, 2023, 10:00 PM

#

tldr NMS stupid
i probably could just use the obfuscated method but that feels like giving up
also i checked, getCanonicalName returns the md mapping EntityPlayer

#

im out of ideas

young knoll Sep 22, 2023, 10:02 PM

#

What are you trying to do

smoky oak Sep 22, 2023, 10:03 PM

#

get a class instance (EntityPlayer) from spigot mappings and call a spigot mappings method in it

#

methods are obfuscated for some reason

#

like it spits out a EntityPlayer instance, but the fields in it are this

young knoll Sep 22, 2023, 10:06 PM

#

Yes?

#

What did you expect

smoky oak Sep 22, 2023, 10:06 PM

#

that if i get a spigot mappings object it has spigot mappings methods

young knoll Sep 22, 2023, 10:07 PM

#

Spigot mappings are mostly gone now

smoky oak Sep 22, 2023, 10:07 PM

#

can i get an answer thats not a 'you're doing it wrong' for once? please?

young knoll Sep 22, 2023, 10:08 PM

#

Spigot mappings only exist for classes afaik

#

Methods and fields are all obfuscated

chrome beacon Sep 22, 2023, 10:08 PM

hm in that case

this is what displays on the mappings page

remote swallow Sep 22, 2023, 10:09 PM

for method and variables its obsfucated

the only spigot mapping is class name

Question
if getHandle is supposed to return the mojmap why do i get the spigot mappings class

you cant use mojmaps if you use want reflection

young knoll Sep 22, 2023, 10:13 PM

#

Yes reflection does not get remapped

remote swallow Sep 22, 2023, 10:13 PM

because you have to compile to obsfucated, and special source doesnt remap reflection

young knoll Sep 22, 2023, 10:14 PM

Then it might be that the input you have is somehow incorrect.
#get() expects a key and will use what you provide to look up that value.
If the key doesn't match or doesn't exist in the map, then it will return null.

Using the WorldCreator.copy(World) -> Copies the generator settings and not the builds inside.

Didn't work but in the process I found another fix:

// OLD
return Bukkit.getServer().createWorld(new WorldCreator(target));

// NEW
WorldCreator defaultIsland = new WorldCreator(target);
defaultIsland.environment(World.Environment.NORMAL);

return defaultIsland.createWorld();

In the Copy function ^

not really a spigot-related question, but... if mojang were to remove a method (non-replacable by myself without huge hassle) i'm using in a lib, what is the "best" way of removing it? straight up removing everything, commenting & deprecating?

It’s because null is ambiguous

Try casting the null to Instant

Try BanList<PlayerProfile> banList = Bukkit.getBanList…

And then use addBan with that object

Yeah it would have to take a Class as a param

echo basalt Sep 22, 2023, 11:59 PM

make a weird generic enum

public class BanType<T> {

  public static final BanType<PlayerProfile> PROFILE = new BanType<>();
  ...

  private BanType() {

  }

bit of a weird pattern

change which mob is displayed in the spawner to make it look like a custom entity

    @EventHandler
    public void onSpawnerSpawn(SpawnerSpawnEvent event) {

        CreatureSpawner creatureSpawner = event.getSpawner();
        if (!creatureSpawner.hasMetadata("mythicMob")) return;

        event.setCancelled(true);
        String name = (String) creatureSpawner.getMetadata("mythicMob").get(0).value();
        Spawner spawner = spawnerManager.getSpawner(name);
        if (spawner != null) spawner.spawn(event.getEntity().getLocation());

    }```
This way I made it generate a custom entity, I would like to change the visible entity of the block

I just poke fun at messing with the internals

halcyon hemlock Sep 23, 2023, 11:01 AM

#

if you know that much about the internals, can you tell me how the first play packet works

torn shuttle Sep 23, 2023, 11:01 AM

I think I might've been working a bit too much, I can feel my wrist starting to strain again

echo basalt Sep 23, 2023, 11:01 AM

if someone asks me a spigot question I just see how it works

uhh

#

it's been a couple years

#

but it went like this iirc

halcyon hemlock Sep 23, 2023, 11:02 AM

#

after the player joins the server, and the server sends back the login success packet

Is it possible to write a plugin using only craftbukkit?

remote swallow Sep 23, 2023, 11:02 AM

#

no

shadow night Sep 23, 2023, 11:02 AM

#

why no

halcyon hemlock Sep 23, 2023, 11:02 AM

#

shadow night Is it possible to write a plugin using only craftbukkit?

you can probably modify the original minecraft source and literally integrate your plugin

echo basalt Sep 23, 2023, 11:02 AM

#

There are multiple phases

Handshake
Login
Configuration (1.20.2)
Play

With handshake the client opens a connection and sends either a "status" or "login" packet

mcp

echo basalt Sep 23, 2023, 11:03 AM

#

If it's a status packet the server replies with motd

remote swallow Sep 23, 2023, 11:03 AM

#

remote swallow no

unless you want to use reflection **

echo basalt Sep 23, 2023, 11:03 AM

#

If it's a login packet the server replies with something else and goes into the login phase

#

something like that

#

encryption happens after etc etc

#

might be getting phase names wrong

#

I haven't touched this since uhh

#

early 2021

shadow night Sep 23, 2023, 11:03 AM

#

I remember I had issues getting the handshake packet to work while making bots

Hello, i dont find any event to check if a playere started a raid so I'm wondering, is there an event for it ?

halcyon hemlock Sep 23, 2023, 11:04 AM

I've completed motd and stuff

jagged thicket Sep 23, 2023, 11:04 AM

jagged thicket what is the best way to make a team chat

figured it out 💀

halcyon hemlock Sep 23, 2023, 11:04 AM

echo basalt Sep 23, 2023, 11:05 AM

#

Yeah so

halcyon hemlock Sep 23, 2023, 11:05 AM

#

I've done this much

#

and you can join server and it gets to the "Joining world..." screen

#

but you have to send back some play packet with a lot of registry and nbt stuff

shadow night Sep 23, 2023, 11:05 AM

halcyon hemlock

There was this cool thing called eaglercraft and it relied on websockets, so I made a similar thing for it before

echo basalt Sep 23, 2023, 11:06 AM

#

Client sends handshake (0x00)
VarInt - Client protocol version
String - Address used to connect
UShort - Port used to connect
VarInt (1/2) - Next state

1 - Status (send motd)
2 - Login

#

It can also send a legacy handhake (0xFE) which is just a 0x01 byte

#

make sure you don't catch your server on fire

halcyon hemlock Sep 23, 2023, 11:07 AM

#

echo basalt make sure you don't catch your server on fire

yeah I ignore packets if packet len < 2

#

doesn't seem to affect anything

echo basalt Sep 23, 2023, 11:07 AM

#

Anyways if it's login

#

The client sends a Login Start packet in the new phase, so packet ids reset

halcyon hemlock Sep 23, 2023, 11:08 AM

#

echo basalt Sep 23, 2023, 11:08 AM

#

0x00 - packet id
String (16 chars) - Player username
uuid - Player Id

halcyon hemlock Sep 23, 2023, 11:08 AM

#

for the login success

echo basalt Sep 23, 2023, 11:09 AM

#

The configuration phase is where plugin channels are enabled

halcyon hemlock Sep 23, 2023, 11:09 AM

#

write the

total len
packet id
uuid
username len
username

halcyon hemlock Sep 23, 2023, 11:10 AM

#

echo basalt The configuration phase is where plugin channels are enabled

heh

echo basalt Sep 23, 2023, 11:10 AM

#

#

So you sent login success

#

Now we need login acknowledged which is just an empty packet telling the client to switch to the Configuration phase

#

just a 0x03

halcyon hemlock Sep 23, 2023, 11:11 AM

#

oh

#

when receive 0x03 on what state

echo basalt Sep 23, 2023, 11:12 AM

#

You send a 0x03 on Login

#

and we switch to Configuration

#

the configuration phase is a bit icky

#

But it's basically just where you send all your registries and stuff

#

in nbt

#

You have pre-made json versions for the default registry data

#

But this is where you send your custom biomes and stuff

halcyon hemlock Sep 23, 2023, 11:15 AM

#

im using 1.17.1

#

lul

#

what version should I even build the server for

#

latest = easier?

echo basalt Sep 23, 2023, 11:15 AM

#

uhh no

halcyon hemlock Sep 23, 2023, 11:15 AM

#

right now its neutral

echo basalt Sep 23, 2023, 11:15 AM

#

let's see for 1.17

#

all the info I was giving is for latest rip

halcyon hemlock Sep 23, 2023, 11:16 AM

#

i thin 0x03 login is same

echo basalt Sep 23, 2023, 11:16 AM

#

Okay there's no configuration phase in 1.17

halcyon hemlock Sep 23, 2023, 11:16 AM

#

when login is acknoledged then what

echo basalt Sep 23, 2023, 11:16 AM

#

So you go straight into Play

halcyon hemlock Sep 23, 2023, 11:16 AM

#

oh that'd make sense why it says joining world

echo basalt Sep 23, 2023, 11:16 AM

#

Because there's still some data that needs to be sent so that the client can render the world

halcyon hemlock Sep 23, 2023, 11:16 AM

#

its a very big packet

#

also can I add u

echo basalt Sep 23, 2023, 11:17 AM

#

you already did

#

I don't remember the exact packets you needed to send

#

but I'm pretty sure it was uhh

#

chunk packets

halcyon hemlock Sep 23, 2023, 11:17 AM

#

directly?

echo basalt Sep 23, 2023, 11:17 AM

#

well you're in the play phase now

halcyon hemlock Sep 23, 2023, 11:17 AM

#

yes

#

dont u need to send anvil stuff

echo basalt Sep 23, 2023, 11:18 AM

#

anvil is just a storage format

#

chunk packets are picky

#

#

send a chunk packet and a teleport player packet iirc

#

or a respawn packet

#

might be both

halcyon hemlock Sep 23, 2023, 11:19 AM

#

wait

#

what

#

whats the order

#

I sent the login succes

echo basalt Sep 23, 2023, 11:19 AM

#

uhh

halcyon hemlock Sep 23, 2023, 11:20 AM

#

then send chunk packets?

echo basalt Sep 23, 2023, 11:20 AM

#

Login success -> Join game

#

starting to remember

halcyon hemlock Sep 23, 2023, 11:20 AM

#

echo basalt Login success -> Join game
