I'm just trying to run a spigot plugin in a development enviroment to test a few things. I have zero plugin dev, but copious modding experience. There has gotta be a thing where I can run the plugin in the development enviroment without having to compile it each time right?

[river oracle]

servers aren't friendly with hot reloading if you need you can just set this up yourself

spigot nor paper comes with any utilities to just start a server from your IDE out of the box afaik

[eternal night]

....

[river oracle]

I'm still trying to wrap my monkey brain around this!! How ta fuq do I go about making a api module for my plugin . I want to depend on some libraries I relocate but if I add them as a compileOnly dependency SHIT EXPLODES and all hell breaks loose.

[eternal night]

https://github.com/jpenilla/run-task

[analog mantle]

I just wanna test this plugin without having to compile it each time.

[eternal night]

fantastic gradle plugin to start a server straight from your IDE for your plugin ^

should support hot reloading fine when started in debug mode

[young knoll]

Yeah but it can’t start a spigot server

👀

[eternal night]

indeed

personal issue I think

[young knoll]

[eternal night]

See @river oracle when coll sends the gif its more threatening

[river oracle]

yeah see this is what I mean

I need staff now

[young knoll]

That’s cuz I actually have a hammer

[eternal night]

and you look more like yoshi yea

[young knoll]

Y2K has one of those novelty foam hammers

[river oracle]

I should have never turned down the offer of reccomendation from Conclure. I mean I could have threateningly sent the gif!!!

giving off miles vibes

[river oracle]

actually

my name is Y2K_ to you buddy

only the real ones call me miles

I hate to be that guy perpetuating the very serious paper spigot beef, but how could a paper contributer ever be a real one

on the bright side I will send you a video of my cat as a peace offering

@eternal night I sent the peace offering

[eternal night]

wait

[eternal night]

this you ?

with the shitty little 8 there

[river oracle]

yeah :P wait till I get inventory PR going

[eternal night]

I am more of a spigot contributor than you are

[river oracle]

I can separate that into atleast 10

[eternal night]

how can you be the real one

[river oracle]

😨 listen man we can talk this out

[eternal night]

@young knoll this guy hasn't even managed double digits yet

who is this guy

[river oracle]

@young knoll ban him bro ban him

he has too many valid poitns

I CANT TAKE IT

lay off bro I just sent you a video of my cat couldn't you be a bit nicer to me

[river oracle]

ayo check under Y2K_ or something I think I have like 1 or 2 commits under than too

[eternal night]

I am a dog person 💔

[river oracle]

dude

literally L

fuck you

[eternal night]

1 commit

[river oracle]

okay we are beefing now

[eternal night]

under Y2Kwastaken

[river oracle]

beast I'm at 9

once MD merges my next I will finally be in the "double digit club"

[eternal night]

[inner mulch]

yo guys do you like the open closed principle

[river oracle]

you do a lot of talk for someone who hasn't contributed to Inventory PR

[river oracle]

wrong crowd man I'm not a nerd I just code shit

who tf cares about OOP princples

[eternal night]

I have other projects to maintain

and no time

damn you uni

[river oracle]

I have UNI too??

your point!!??!?!

[eternal night]

Pleb uni I presume

[river oracle]

I'm actually in highschool I'm just dual enrolled full time at my local accreddited university

[eternal night]

I see

[river oracle]

whose is that

what gradle version do i need to use

[eternal night]

what gradle version are you on

I'd try with latest

[analog mantle]

8.6-all isn't latest?

[eternal night]

should be

is this in a module or something

[analog mantle]

uh

idk

[eternal night]

do you use a root build.gradle.kts and then modules inside of its settings.gradle.kts

[analog mantle]

Yes i use a kotlin gradle

[eternal night]

not really what I was asking sorry 😅 can you share your build.gradle.kts

?paste

[undone axle]

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

[quaint mantle]

huh

[eternal night]

Enjoy

[quaint mantle]

isn't byte final anyway

[eternal night]

final?

oh

[quaint mantle]

ye its a final class ion need super

[eternal night]

yea but generics don't care

[analog mantle]

It's not my plugin like I explained, however here's the source
https://github.com/GrimAnticheat/Grim/blob/2.0/build.gradle.kts

[eternal night]

that project is using gradle 7.4

in its wrapper

I presume those are not compatible

[analog mantle]

I just changed the version to 8.6-all

[eternal night]

works perfectly fine for me

[analog mantle]

with the plugin added?

[eternal night]

yea

[young knoll]

Paper tax

[eternal night]

https://pastes.dev/rBtNYcu2n5

the diff in question ^

(emitted changes to gradlew and gradlew.bat)

[analog mantle]

send me your whole build.gradle please

[eternal night]

https://pastes.dev/I6RdOW48Iy

make absolutely sure your gradle wrapper is running 8.6

[analog mantle]

yea idk why but your impl works fine

[eternal night]

nice 😅

idk how well it does hot re-loading, I think partially depends on IJ quirks

like

it does hot-reloading

it might not do deletion instructions

[young knoll]

Is that more or less jank than /reload

[eternal night]

less

hot swapping things vs the fucked classloader close and re-open bs

[analog mantle]

Not a issue

[eternal night]

Well, best of luck with it

[young knoll]

Idk replacing bytecode live sounds pretty janky

[eternal night]

I mean, the JVM at least properly supports it

[young knoll]

It’s been a while but last I remember trying it I could only edit stuff

Trying to add or remove anything just imploded

[buoyant viper]

there's a replacement for hotswap that supports it i think

started with a d

[young knoll]

Is this a deez nuts setup

[eternal night]

DCEVM

but its kinda dead

most stuff is part of JetBrainsRuntime tho

but yea, for removal you need a custom flag too

[young knoll]

Smh IntelliJ isn’t the only ide

[eternal night]

Their runtime is packaged separately

[remote swallow]

i love jbr

its so useful

[eternal night]

[young knoll]

So just never delete things

Got it, best programming strategy

[cedar flint]

This is my anvil listener code. Btw no outside classes with InventoryClick affect it, but for some reason when I for example combine a pickaxe and a custom enchanted book with Protection and a compatible custom enchantment the output slot does show the item with the correct lore and custom enchantment, but I cant take it out. and it doesnt get past: if (event.getSlotType() == InventoryType.SlotType.RESULT && event.getRawSlot() == 2) { so it is not like the methods get activated again.
Here is my code:

Thank you for helping in advance

[young knoll]

On you’re using inventory click event

Use PrepareAnvilEvent

[eternal night]

Ah it was -XX:+AllowEnhancedClassRedefinition

[remote swallow]

-XX:+AllowEnhancedClassRedefinition -XX:+AllowRedefinitionToAddDeleteMethods -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:5005 -Xlog:redefine+class*=info -XX:HotswapAgent=fatjar

[eternal night]

right downloading the fucking hotswap

did they merge t hat into JBR

I recall they had it in DCEVM 11

it does not

fucking sadge

[remote swallow]

i didnt know about it till like a month ago and got annoyed when my lambdas wouldnt hotswap

[young knoll]

Those are some wild startup args

[eternal night]

hotswap agend is wild

[young knoll]

So you just what

Run that and then attach from your ide

[eternal night]

Yea

attach from IDE in remote JVM debug

[young knoll]

What’s fatjar

[eternal night]

a flag for the hotswap agend

[young knoll]

Is it meant to point to something tho

[eternal night]

no

did you download JBR and place the hotswap agend release in the folder it belongs to?

das the important part

[young knoll]

No I’m not even on my pc :p

[remote swallow]

put it in libs/hotswap iirc

[eternal night]

yea

oh

why you asking then

[remote swallow]

i wasnt

[eternal night]

not you

coll

[remote swallow]

oh

its lib not libs

but same thing

[young knoll]

Idk incase I wanted to try it tomorrow

Google is for nerds

[eternal night]

facts

[rare rover]

got a question for y'all, since metadata is hella slow compared to other things, and currrently i am accessing the player's pickaxe's metadata every block which a no no, on my part

how else would i approach this

store the data i need in memory? Or what

[young knoll]

You can do that, yeah

[rare rover]

okay.. So how would i do this?

should i store it in the player's metadata instead then grab it everytime they join?

then store it in memory, ect

[young knoll]

You can, yeah

What exactly are you storing

[cedar flint]

I recoded it now using PrepareAnvilEvent, but still I cant take the item out of the output slot.

[young knoll]

Hmm, I’ve never had issue when doing it that way

Oh wait wait

I think you need to set a non-zero cost

[cedar flint]

Il try

omg thank you. You are a god. It works!

[rare rover]

oop, sorry lmao. Just some integer values and such for the pickaxe enchants

which im grabbing every block broken and is hella slow (as shown in the profiler)

which is a no no

[young knoll]

I didn’t think cloning ItemMeta was that slow

But I guess it makes sense

[remote swallow]

store the data urself and just track the slot location

[rare rover]

it was 100% the bottleneck of my system

~70ms for the PDC alone

was 140ms in total

[rare rover]

👍

i could also lock the pickaxe in slow 1

[remote swallow]

people dont like that

[echo basalt]

sounds like you had way too much pdc

[remote swallow]

some people have it in there 7th slot witha keybind

[rare rover]

i'm creating it only once but im grabbing each enchant value everytime

[buoyant viper]

ah yeah that

[rare rover]

alr, wouldn't it just be easier to store it in the player's PDC?

instead of the item and i can grab it when the join and unload it when they leave

[remote swallow]

depends what data it is

context?

[rare rover]

its literally just integers

one sec

[remote swallow]

might be fine to do that then

just do periodic saving for modification and crash protection

[balmy jacinth]

sorry

[rare rover]

all im storing

[rare rover]

👍 ty

will do

[young knoll]

I mean if it’s in the players pdc it’ll already be periodically saved

Assuming you update directly to the pdc

But putting it in a map is probably better

[rare rover]

that's what im doing rn and its slow, i'm wanting to use a map instead

alr

[slender elbow]

something something getting the itemmeta is expensive

[plucky rock]

            if (attacker instanceof Spider) {
                if (AttackerName.contains("§5King of Spider's Servant")) {
                    new BukkitRunnable() {
                        @Override
                        public void run() {
                            Vector up = player.getVelocity().setY(0).setX(0).setZ(0);
                            player.setVelocity(up);
                            player.sendMessage("Debug3333");
                        }
                    }.runTaskLater(this, 20L * 1L);

                }

            }```
any1 know why the bukkitrunnable doesn't run

ill swap to PDHs later

[drowsy helm]

pretty sure Bukkit.getScheduler() is the more accepted way of doing it

AttackerName.contains("§5King of Spider's Servant") wont match

[plucky rock]

oh

[drowsy helm]

use PDC

[plucky rock]

the name thing worked tho?

also yea ill swap to PDCs

[drowsy helm]

dont see why that owuldnt run otherwise

[plucky rock]

huh

ok

[drowsy helm]

is it inside the main class?

[plucky rock]

ill try swapping to PDC

no

ill send the full

code

[drowsy helm]

'this' should be plugin instance

[young knoll]

Then you can’t use this for the runnable

That shouldn’t even compile

[plucky rock]

ohh

ok

huh

i thought this was the plugin not the class

i mea this not this

[young knoll]

this is always the current instance of whatever class you use it in

[plucky rock]

ah

ok

[plucky rock]

cool

ty

didnt know thats a thin

thing

[plucky rock]

that was the error

however

            if (attacker instanceof Spider) {
                if (AttackerName.contains("§5King of Spider's Servant")) {
                    new BukkitRunnable() {

                }

            }```
this doesnt cancel momentum

soo

no clue why

[young knoll]

Did you try running it after 1 tick

Rather than 20

[plucky rock]

yea

i just tested that

ot worked tysm

ur awsome

[shut field]

how do you deserialize a HashSet<>?

more specifically

 Set<String> set = memorySection.getKeys(false);
        for(String path : set){
            String rawPath = path;
            path = memorySection.getCurrentPath() + "." + path;
            if(rawPath.equals("chunks")){
                HashSet<Long> chunks;
                chunks = (HashSet<Long>) Sylv.data.getConfig().get(path);
                result.setChunks(chunks);
            }
}

what do I use instead of .get() which returns a MemorySection, because there is stuff like, "getList()" but no "getSet()"

do i have to turn the HashSet to a list before serializing

[echo basalt]

a set and a list are really similar

You could just load it as a stringlist and convert?

[young knoll]

Yeah you’ll have to convert it to a list

Spigot can’t serialize sets

[shut field]

I see

not very difficult ig

Arrays#asList(HashSet#toArray)

[young knoll]

Can’t you do new ArrayList(set)

[echo basalt]

you can

p sure

[worldly ingot]

Yeah it takes a Collection

[slender elbow]

no u

[rare ridge]

Hello, I need to implement a cooldown on my custom item, but for some reason the cooldown applies to the vanilla item, how can I fix this? (cooldown is implemented in the form of logic like end pearls)

[young knoll]

Cooldown is for the entire material

Not much you can do

[rare ridge]

Is it possible to distribute it only to your subject?

[young knoll]

What

[worldly ingot]

If you mean to only apply it to a specific item, no, you cannot do that

That's not how Minecraft's cooldown system works. It applies to the whole item type, not a specific item stack

[young knoll]

Sadly

Mojang plz?

[echo basalt]

I feel like it'd be a pain in the ass to track that

[worldly ingot]

otherwise you'd just be able to switch to a new ender pearl and use it instead

[worldly ingot]

It would just have to be timestamped in the NBT, not too bad all things considered

[echo basalt]

or like

timestamp the meta hash?

[worldly ingot]

idek what that means

[echo basalt]

like

put the meta on cooldown not the item type entirely

[worldly ingot]

Oh, hash the meta and assign a value to it lol

[echo basalt]

yeah

[worldly ingot]

but then if its meta changes

[echo basalt]

no cooldown

ezpz

[worldly ingot]

suddenly, no more cooldown

😎

[young knoll]

What if it just has empty meta

[echo basalt]

0

you aren't gonna be expecting ppl to /rename their enderpearls in 0.1ms

help im sleepy

[young knoll]

You never know

[remote swallow]

keybind

some servers give irename from essx

[echo basalt]

bro fuckin make it configurable n fuck off

ezpz

[rare ridge]

oh ok, thanks

[young knoll]

You could probably jank it with some resource pack magic

[rough ibex]

or you could track the cooldown yourself

and just cancel the applicable event

[echo basalt]

prob

just like

actionbar an overlay

bunch of offsets n stuff

it'd look a bit janky

but if you fine tune it all

[rare ridge]

But if you create an item with the NBT tag and put a cooldown on it, is this even feasible?

[river oracle]

you can't really implement this yourself without a mod the real strategy here is to timestamp your PDC with bukkit. The downside is you don't get that cooldown effect you likely desire.

I'd suggest maybe doing something with the item/meta to make it look different when its cooling down. If you're already using a texture pack applying different model data is the obvious solution here

[rare ridge]

got it, thanks for the answer

[quaint mantle]

a question nms is for a server version right?

if i want to make plugin work on all versions i would have to do extra coding right?

[remote swallow]

if it requires nms yeah

if you only need api you just use the lowest api you wanna support

[quaint mantle]

wym?

[remote swallow]

do you use nms currently

[mighty gazelle]

How can I send "you are swear1 "?
Code:

        }
        return word.substring(0, 2) + "*".repeat(word.length() - 2);
    }
    private static final String[] knownMessage = {
            "swear1",
            "swear2"
    };
    @EventHandler
    public void onPlayerSendMessage(AsyncPlayerChatEvent event) {
        Player player = event.getPlayer();
        String message = event.getMessage();
        String blocketmessage = "Swear Word";

        for (String knownMessage : knownMessage) {
            if (message.contains(knownMessage)) {
                player.sendMessage(blocketmessage);
                String maskedMessage = message.replace(knownMessage, maskSwearWord(knownMessage));
                event.setMessage(maskedMessage);
                for (Player allplayer : Bukkit.getOnlinePlayers()) {
                    if (allplayer.hasPermission("group.admin")) {
                        allplayer.sendMessage("Der Spieler " + player.getName() + " hat versucht " + message + " zu sagen");
                    }
                }
            }
        }
    }
}

[sullen marlin]

You want to use a loop with an int counter not enhanced for loop and then print counter value

[sterile flicker]

Is there no getClientViewDistance in 1.12.2?

[sullen marlin]

I doubt the client had that in 1.12.2

[sterile flicker]

        int chunkDistanceX = Math.abs(playerChunk.getX() - npcChunk.getX());
        int chunkDistanceZ = Math.abs(playerChunk.getZ() - npcChunk.getZ());

        return chunkDistanceX <= viewDistance && chunkDistanceZ <= viewDistance;
    }``` I need to process the player's approach to the NPC in playermovevent, or more precisely the moment when the player sees the npc in order to send packets

I am currently sending packets for fake nms npc only when logging into the game

[sullen marlin]

Just pick a distance or use view distance

There's no reason it has to match

[sterile flicker]

view-distance=10 that is, can I use the default value from server.properties?

[rotund ravine]

Sure

[sterile flicker]

it is too big, I have moved to a very large value and it is still being executed

that is, I will move 100-200 blocks away and only then will it stop

[terse ore]

would it be possible to replace a player with a zombie? So instead of displaying a player to other players it displays a zombie

[shadow night]

I thought of that before, I'd like to know the answer too

[rotund ravine]

I mean there was that diguise plugin that did it

Sadly you can’t do it for the player hidden

[terse ore]

player hidden?

you mean the one who disguises

[sterile flicker]

what is the difference between CLIENTBOUND and SERVERBOUND nms fake entity

[fierce whale]

Is there a way to get blockface of bed?
this code doesn't works 😦

            Bed bed = (Bed) block.getBlockData();
            System.out.println(bed.getPart());
            Location loc = block.getLocation();
            bed.getFacing();

[lost matrix]

Well this code has a lot of dead code in it. What do you expect it to do?

[fierce whale]

I wanna get another location of bed block

[lost matrix]

Then get the block in the facing direction

[fierce whale]

how can I get the facing direction of block?

[lost matrix]

Bed bed = (Bed) block.getBlockData();
BlockFace facing = bed.getFacing();

[fierce whale]

I did

but (Bed) casting doesn't work

[lost matrix]

Then show your code

[lost matrix]

Wrong import

[fierce whale]

is org.bukkit.block.data.type.Bed wrong?

[lost matrix]

Thats the right import

Explain "doesn't work"

[minor junco]

try as any

¯_(ツ)_/¯

[fierce whale]

It throws ClassCastException

[minor junco]

Get the type of the block

[lost matrix]

Did you check if the Block is actually a Bed first?

[minor junco]

And print it out, doesn't seem like the block is actually a Bed

[fierce whale]

yeah I checked 😓

[minor junco]

Well, check again 😆

[lost matrix]

Ok before anyone gives any more advice:
Show your whole code and any exception you encountered.

This could have been solved minutes ago

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.

Thanks so much

WTF

[fierce whale]

my eye is gone because of lot of code :🥲

[minor junco]

That's why you should separate things out a bit imo

But that's for a different topic

[sterile flicker]

?

[fierce whale]

anyways, thanks 🙂

[lost matrix]

Btw... what am i seeing here?

[fierce whale]

Does it have any problems?

[lost matrix]

that looks like

pdc.clear();

But with a lot of unnecessary code

[fierce whale]

OMG

[sterile flicker]

please tell me someone)

[fierce whale]

there is no clear method in pdc

[lost matrix]

ClientBound means its heading is bound to the client (The packet will be sent to the client from the server)
ServerBound means the heading is bound to the server (The packet will be sent to the server from the client)

Those have nothing to do with nms fake entities. Those are only prefixes for packets so you know where they will be sent to.

[lost matrix]

Why dont you just create a new empty pdc? (I assumed it was a map)

[fierce whale]

cause it's final field

[sterile flicker]

can you take a look at my current code of my nms npc entity?

[lost matrix]

What version? I was honestly about to prepare breakfast and coffee...

[sterile flicker]

now it looks much better, but there are questionable points that make something not work as expected

[sterile flicker]

1.12.2 it shouldn't take you long, you can come back to it when you have free time) I appreciate your help

[lost matrix]

Sure, send it

[sterile flicker]

The NPC entity spawns well only when the player enters the sevrer.

[11:50:51 INFO]: visible```

after deleting the entity and when I go back to it, it only shows up in the tab but does not spawn

[lost matrix]

Those two lines should be removed.
You dont want a fake entity to be added to the world.

[sterile flicker]

I'm also worried that the entity will disappear for other players and not just for 1 player who has moved away from the entity.

[lost matrix]

Btw in 1.12 you can just listen to the ChunkLoadEvent and send All NPCs in that chunk to all players.
Then in the ChunkUnloadEvent you simply hide them from all player.
The client decides himself when to display them.

No need to listen for all that PlayerMove stuff

[sterile flicker]

thanks

[lost matrix]

Hm. Honestly if you want a proper fake entity, then you dont need to extend EntityPlayer.
Just create a new class with all the needed properties (GameProfile etc) and then send packets to players.
Here is how that looks for one of my implementations:

The sendTo simply looks like this

[sterile flicker]

how do I hide a fake player?

Player#hidePlayer?

ChunkUnloadEvent

[lost matrix]

Send the despawn and remove info packet

[sterile flicker]

1.12.2)

[lost matrix]

Yes in 1.12 it should be the same. Despawn packet or its called entity destroy i think, and after that you send the info hide packet
or its called info update with the enum action REMOVE

[sterile flicker]

PacketPlayOutEntityDestroy

?

[lost matrix]

This one hides the entity, right

Cant remember 1.12 protocol by heart. That came out before i started developing

[sterile flicker]

should I send packets to all players or should I send packets to all players in the chunk?

ChunkLoadEvent

[lost matrix]

To all players

[sterile flicker]

the entity stopped spawning after deleting those two lines

[lost matrix]

Good. This means almost all of your code was flawed.

Now make sure to send those packets and debug it.

[sterile flicker]

exactly, I did not send the PlayOutNamedEntitySpawn packet before, it kicked me with errors

Maybe it will work now

[lost matrix]

Well... sending an empty packet confuses the client ofc.

[sterile flicker]

Show me your method setupSpawnPacket please

[sterile flicker]

so connection.sendPacket(new PacketPlayOutNamedEntitySpawn(entity.getBukkitEntity().getHandle()));

[lost matrix]

entity.getBukkitEntity().getHandle() is the same as just entity

unfortunately, I see the entity only in the tab ```java

[lost matrix]

Stop filtering your spawns by distance or if they are in the same chunk.
Also: You need to send the player info before you can send the named entity.

Bc otherwise you are trying to spawn a player with completely unknown properties.

[lost matrix]

You never add the entity to the world, so the server has no idea that it exists so you cant rely on the
server to know if its in a chunk or not. Thats something you have to track yourself.

[sterile flicker]

i can add entity id argument to the packetconnection.sendPacket(new PacketPlayOutEntityDestroy(ep.getEntityId()));

Hi, I am writing a plugin for minecraft and I have a question. How to make a file with localization correctly. So that plug-in users can change any plug-in text into their own language in the config. I would also like the localization file to be uploaded only 1 time.

[sterile flicker]

Why not just add an entity to the world?

[lost matrix]

Anyways you should take two steps back and maybe create a few more classes.
This is currently so patched up and messy.
Create an NPCManager which tracks all your NPCs and in which chunks they are.

[lost matrix]

1. Create a config file
2. Load its values when the server starts
3. Use the values in your code

[sterile flicker]

?

[sterile flicker]

does your npc plugin have a github?

I want to see it

when I added the entity to the world, minecraft crashed)

[proud badge]

Do all bukkit async tasks run on the same seperate thread, or does each async task create its own thread?

[lost matrix]

Was a while back when i looked into this but i think they use some sort of thread pool or factory.
So not the same thread for all tasks.

[lost matrix]

Nope thats closed source.

[lost matrix]

Dont add them to the world

This makes them not virtual anymore

[proud badge]

So if my server has only 3 threads (one for the main) does that mean I can only have two async tasks running at the same time? Or how many can I have?

[umbral ridge]

🤓

nerd question

[sterile flicker]

I don't quite understand how I can track entities in a separate class and how to use this class.

[umbral ridge]

no.. threads are a separate thing. you can run a lot more async tasks

[sterile flicker]

and how to interact with entity?

playerinteractentityevent

not working

[lost matrix]

You should def use an NPC library like citizens then and write a few more plugins.
Because this approach (Having a manager class and tracking stuff) is something you will need for every plugin.

[echo haven]

hey gang just wondering if there's a way to create an itemstack of a item frames that have their visibility toggled off?

[tender shard]

you can add a custom PDC tag to the itemstack and then in HangingPlaceEvent, check the itemstack and if it has that tag too, then make the placed itemframe invisible

[icy beacon]

Alex what time is it

[tender shard]

11:44

[icy beacon]

Thx

[echo haven]

crud ok a little messier than I was hoping but ok ok, thank you 🙂

[ivory sleet]

Pretty much yes

but u can have a lot more than 3 threads

[drowsy helm]

3 threads is not realistic

[ivory sleet]

when a thread is blocked (lets say it awaits some io stuff) its then suspended

[tender shard]

he's probably talking about some mc hosting company that sells "4gb 2 vcores (threads)" or sth similar and the answer is, he can still schedule 100+ async tasks

[drowsy helm]

yeah the whole physical/virtual/OS thread thing can be confusing

[ivory sleet]

Myea, tho its not always practical

The amount of available processors is usually a good number to base ur thread pools and other mechanisms on (well ofc doesnt rly apply to virtual threads)

[inner mulch]

When i create more threads than my PC has and let them do tasks at the same time will it crash?

[tender shard]

ofc not - open your task manager

[rotund ravine]

Probably not

Depends on the tasks ur making the jvm do memory limit is a thing

[tender shard]

I only have 8 cores and not 1500

[rotund ravine]

I think ur lying

[inner mulch]

Threads are infinite?

[rotund ravine]

No

Obviously limits but yeh

[inner mulch]

I thought there where always 8 cores and then 16 Thresds so always double

[drowsy helm]

physical threads =/= virtual threads

[inner mulch]

Okay

[drowsy helm]

there is a limit to how many threads you can address in java but it's pretty high

high enough to the point where if you are hitting that limit you are doing something very wrong

[ivory sleet]

You have os threads then jvm threads getting mapped to those, and then virtual threads and coroutines getting mapped to the jvm ones more or less

a mapping can usually even be surjective

[inner mulch]

What if i have a thread for each method will i have the fastest program ever?

[ivory sleet]

depends

[drowsy helm]

https://www.quora.com/What-are-the-differences-between-threads-and-cores-from-a-programming-language-perspective

However, you can't just creat a 100 threads and say I have 100x performance. This is where the cores come into picture.

[ivory sleet]

Usually you either wanna minimize waiting time (that is doing something async like downloading a file), or u wanna distribute a computation that takes long time

when distributing a computation, its rarely ever worth to allocate a billion threads or so, as its still only gonna use what cpu hardware resources u have available, so limiting it to the amount of available processors is usually reasonable

[inner mulch]

Ok

[upper hazel]

Packet based NPC's don;t exist on the server

Only your plugin knows about them, and the client you told

then how to implement what 7smile7 was talking about

Then in the ChunkUnloadEvent you simply hide them from all player.
The client decides himself when to display them.```

here's an example. The API is just some interfaces that doesn't do anything: https://github.com/JEFF-Media-GbR/AngelChestAPI

Show your manager class.
Without that you have exactly a 0% chance getting this to work

    }

}```

I do not know what to add to the manager

[inner mulch]

What do you want it to do?

[chrome beacon]

you really should stop adding static to everything

[sterile flicker]

but in this case, it shouldn't cause any problems.

[shadow night]

static is almost always a problem.

[lost matrix]

Start by making all your fields private and and remove the static keyword from everything.
After that you should create a class called ChunkPosition which holds x and z ints.
Then expand your class with a Map<ChunkPosition, List<NPC>>

[shadow night]

the few cases where it's okay is like constants or the singleton pattern

[inner mulch]

Static managers are fine arent they?

[chrome beacon]

They're using static on a lot more than just that

pretty much all of their code is static

[inner mulch]

Really?

[hazy parrot]

i wouldn't make my manager classes static

[chrome beacon]

^ this too

[inner mulch]

If there is only one?

Why wouldnt you make it stqtic

[ivory sleet]

Sometimes its appropriate to make your managers singletons, but they shouldn’t inherently be static, only if there is good reason to do so

[cursive loom]

Hello i have a problem with VaultAPI, I try to do an economy plugin with the vault API, I have add the depedencies in my plugin ans I have install vault in the server but when I start the server the plugin was disabled for "No vault plugin foud", do you know how I can fix that ?

[ivory sleet]

Your vision is quite narrow if this is the only reason for u to make something static, you have to consider eventual consumers of your class, maintainability in the long run, does it incorporate statefulness - in such case what about thread safety, is your manager going to be testable, etc

[zinc moat]

but like what does the chatmanager do?

[tender shard]

why do you print "No Vault dependency found" when you're actually checking for an economy provider?

well it looks like you don't have any economy plugin installed

[inner mulch]

Maybe Filter Bad words

[eternal oxide]

You likely don;t have an Economy plugin

[cursive loom]

Yes but I try to do a economy plugin but I need the api from vault to do it

[tender shard]

then why are you disabling your own plugin?

you are supposed to register the economy provider yourself

[icy beacon]

that's just the vault api docs copypaste

[cursive loom]

idk that a good question xD

[cursive loom]

yep

[tender shard]

you have to implement the Economy class yourself and then register it

[shadow night]

or install essentialsx...

[sterile flicker]

I said earlier that the problem is not static abusing, although yes, the code looks better this way

[cursive loom]

Sry for the question I think I just tired xD Have a good day lmao

[shadow night]

then depends on what kinda economy plugin yk

[icy beacon]

i presume an econ provider

when are we getting an ACTUAL economy plugin?

[shadow night]

economy plugin can extend in twenty million branches

[icy beacon]

like, inflation, corruption etc

[shadow night]

damn

[icy beacon]

not just i give money you get money monke

here is top bal

i want my money to depreciate

[shadow night]

that plugin would need to also be a shop plugin and stuff yk

[icy beacon]

let it be so then

i am talking an actual economy plugin

[shadow night]

economy 2000

[icy beacon]

2024*

[shadow night]

lol

let's call our plugin Rubleconomy

what better way to represent a plugin with inflation and corruption than the ruble

[icy beacon]

trueee

actually let it be just an "ActualEconomy" and then there are modes like "ruble", "usd", "yen", etc

that define the rate of inflation, corruption and pricing of goods

[zinc moat]

alrigth

[icy beacon]

and i guess like

pull actual data from some rest

for accurate currency conversion and pricing

[mighty gazelle]

How can I make it so that you can write everything in but only the word is filtered?
e.g. "you are swear1 "
Code:

public class AntiSwear implements Listener {
    public static String maskSwearWord(String word) {
        if (word.length() <= 2) {
            return word;
        }
        return word.substring(0, 2) + "*".repeat(word.length() - 2);
    }
    private static final String[] knownMessage = {
            "swear1",
            "swear2"
    };
    @EventHandler
    public void onPlayerSendMessage(AsyncPlayerChatEvent event) {
        Player player = event.getPlayer();
        String message = event.getMessage();
        String blocketmessage = "Swear Word";

        for (String knownMessage : knownMessage) {
            if (message.contains(knownMessage)) {
                player.sendMessage(blocketmessage);
                String maskedMessage = message.replace(knownMessage, maskSwearWord(knownMessage));
                event.setMessage(maskedMessage);
                for (Player allplayer : Bukkit.getOnlinePlayers()) {
                    if (allplayer.hasPermission("group.admin")) {
                        allplayer.sendMessage("Der Spieler " + player.getName() + " hat versucht " + message + " zu sagen");
                    }
                }
            }
        }

Im trying to make it so composter gets filled instantly after the composter level gets above 1. This code works but updates the composter to filled only if I left click or right click with a non compostable item. I think when I right click with a compostable item in hand, instead of my code running and instantly setting the level to filled, minecraft overwrites it with it's code of progressing the level of composter normally. any way to fix it?

there was a folia fork somewhere that added synchronized to everything to "improve plugin compat"

We need more of such revolutionary thinking

[lost matrix]

I would recommend you to tackle something a bit easier. NPCs are already really hard.
Have you written a lot of other plugins before?

[upper hazel]

I don’t understand how to separate the api and its implementation from each other so that another plugin can connect and use the api and its implementation through maven, but so that the implementation itself in the form of source code or a Jar file is not available

[young knoll]

Basically like bukkit does

Bukkit is the API, cb is the impl

[upper hazel]

i mean how create repository for this

[lost matrix]

You provide two jars. One with only the api (and can be shaded).
And one with the api and its implementation (this will be deployed on the server)

[upper hazel]

but if I connect only the API, I will have access to the implementation

[lost matrix]

The jar with only the API doesnt have an implementation

[sterile flicker]

very little. about 6

[upper hazel]

Sorry, I misspoke, I mean I won’t get it

[lost matrix]

Oh yeah. You dont want that. The api doesnt need to know the implementation.

[sterile flicker]

I handed over my code. can you take one last look at it, now it should meet requirements?

[lost matrix]

?paste

[undone axle]

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

[lost matrix]

🙂

[upper hazel]

and how to access 1 API implementation created for its interface?

[acoustic pendant]

Hey, was wondering if there was a fastest way to do this checks?

[lost matrix]

Use a map

[sterile flicker]

https://paste.md-5.net/amezonitaj.java the only problem is the playerinteractentity event doesn't work and chunkloadevent isn't called all the time when I'm near the entity

[young knoll]

iirc there is Block#getDrops

[sterile flicker]

but overall it works better.

[upper hazel]

I just don’t understand how the api will understand that I am accessing 1 of its implementations through the api

[acoustic pendant]

oh, ok thanks

[upper hazel]

if I connect only api

[sterile flicker]

I had to use the block position because the regular one didn't work in chunkloadevent(*16)

[lost matrix]

You need a gateway where the api user can request the implementation at runtime

[lost matrix]

The manager looks good so far

[upper hazel]

what the gateway

wdym

[tardy delta]

seeing the word nurse over and over is starting to scare me

[lost matrix]

chunk.getX()*16, chunk.getZ()*16 this makes no sense.
Just use the chunkX and Z

isNPCVisible remove this method

[sterile flicker]

but it doesn't work without multiply by 16 in chunkloadevent

[lost matrix]

What exactly doesnt work?

[sterile flicker]

it just throws different coordinates of chunks when I am in the npc chunk, but not the coordinates of the npc chunk themselves.

playerjoinevent is working but chunkloadevent is not

without blockposition

[lost matrix]

Remove this method

    public static boolean isNPCVisible(int chunkX, int chunkZ) {

        int chunkDistanceX = Math.abs(chunkX - Npc.nurseChunk.getX()*16);
        int chunkDistanceZ = Math.abs(chunkZ - Npc.nurseChunk.getZ()*16);

        return chunkDistanceX <= 1.0F && chunkDistanceZ <= 1.0F;
    }

And then use the chunk X and Z.
To get the chunk X and Z from your entity you have to divide its location X and Z by 16

Here as well

[sterile flicker]

and there manager.addNpc(EntityNurse.create("Медсестра", Npc.plugin.getServer().getWorld(Npc.plugin.getConfig().get("world").toString()), nurseLocation).getBukkitEntity(), nurseChunk.getX() * 16, nurseChunk.getZ() * 16);

I need to remove the multiplication by 16 everywhere?

[lost matrix]

Yes. Multiplying by 16 everywhere is kind of pointless. The only thing you need to do is divide the location by 16

[sterile flicker]

if I divide the coordinates of the chunk by 16, do I get the absolute coordinates?

I just need to compare the distance between the npc and the unloaded chunk

[lost matrix]

No it gives you a useless value

[lost matrix]

Why?

[sterile flicker]

if the distance, for example, is more than 10, i need to send remove entity packets

ChunkUnloadEvent

Oh I'm confused

[lost matrix]

ChunkLoadEvent:

1. Get all NPCs in this chunk from your manager
2. Send all players the spawn packets for the NPCs

ChunkUnloadEvent:

1. Get all NPCs in this chunk from your manager
2. Send all players the despawn packets for the NPCs

You never need to check any distance to anything

[sterile flicker]

@EventHandler
    public void onChunkLoad(ChunkLoadEvent event) {
        Chunk chunk = event.getChunk();

        for (CraftPlayer npc : manager.getNpcsInChunk(chunk.getX(), chunk.getZ())) {
                System.out.println("visible");
                for (Player p : Bukkit.getOnlinePlayers()) {
                    PlayerConnection connection = ((CraftPlayer) p).getHandle().playerConnection;
                    PacketPlayOutPlayerInfo info = new PacketPlayOutPlayerInfo(PacketPlayOutPlayerInfo.EnumPlayerInfoAction.ADD_PLAYER, npc.getHandle());
                    connection.sendPacket(info);
                    connection.sendPacket(new PacketPlayOutNamedEntitySpawn(npc.getHandle()));

                    npcSpawned.put(p, true);
                }
        }
    }
    @EventHandler
    public void onChunkUnload(ChunkUnloadEvent event) throws IOException {
        for (CraftPlayer npc : manager.getNpcsInChunk(Npc.nurseChunk.getX() , Npc.nurseChunk.getZ() )) {
                if (npc != null) {
                    for (Player p : Bukkit.getOnlinePlayers()) {
                        if (npcSpawned.containsKey(p) && npcSpawned.get(p)) {
                            PlayerConnection connection = ((CraftPlayer) p).getHandle().playerConnection;
                            connection.sendPacket(new PacketPlayOutEntityDestroy(npc.getEntityId()));
                            PacketPlayOutPlayerInfo info = new PacketPlayOutPlayerInfo(PacketPlayOutPlayerInfo.EnumPlayerInfoAction.REMOVE_PLAYER, npc.getHandle());
                            connection.sendPacket(info);

                            npcSpawned.put(p, false);
                            System.out.println("invisible");
                        }
                    }
                }
        }
    }```can you tell me where I should apply the division by 16

[lost matrix]

First you are going to remove your "npcSpawned" collection because you are not using it in any meaningful way.
Next you should clean up those methods there is too much nesting going on.

Inside your NPC class add the following methods:

public void showTo(Player player) {
}
public void hideFrom(Player player) {
}

After that you simply apply those methods for chunk loads and unloads.

@EventHandler
public void onChunkLoad(ChunkLoadEvent event) {
  Chunk chunk = event.getChunk();
  for (CraftPlayer npc : manager.getNpcsInChunk(chunk.getX(), chunk.getZ())) {
    for (Player player : Bukkit.getOnlinePlayers()) {
      npc.showTo(player);
    }
  }
}

@EventHandler
public void onChunkUnload(ChunkUnloadEvent event) throws IOException {
  Chunk chunk = event.getChunk();
  for (CraftPlayer npc : manager.getNpcsInChunk(chunk.getX(), chunk.getZ() )) {
    for (Player player : Bukkit.getOnlinePlayers()) {
      npc.hideFrom(player);
    }
  }
}

The division comes into play for your NPC manager:

public void addNpc(CraftPlayer npc) {
  int chunkX = npc.getX() / 16; // Something like that. Location X / 16
  int chunkZ = npc.getZ() / 16; // Same here
  npcMap.computeIfAbsent(new ChunkPosition(chunkX, chunkZ), key -> new ArrayList<>()).add(npc);
}

@sterile flicker I changed the unload method again, because your nurse chunk in there is also weird

[sterile flicker]

I can't believe my eyes, what a detailed answer

thanks

[quaint mantle]

Hi , i am writing a plugin about ip but is there a question on my mind that can Player spoof ip and use other Player's ip?

[lost matrix]

Also: You wont be able to use CraftPlayer in your manager. It needs to be your custom NPC or else they dont have your custom methods.

[lost matrix]

The packets going back wouldnt reach the sender again. Spoofing can only be done with a man in the middle attack.
So its very rare to have that happen.

[quaint mantle]

so do you mean only in the middle attack or when server is attacking is possible ?

[lost matrix]

The IP address is taken from the TCP packet (Which builds on the IP packet containing the IP address).
All packets will be sent back to the sender listed in the packet. If you dont actually have that IP address, then the routing
will send those answer packets back to the original owner of that IP address, making your "spoof" practically useless.

You would have to own the entire route or a critical choke point between the attacker and the server.

So right at your servers host location, or right at the house of the spoofed player.

[acoustic pendant]

if (player.getItemInUse().containsEnchantment(Enchantment.SILK_TOUCH))
block.getWorld().dropItemNaturally(block.getLocation(), brokenBlock);

Why is this returning null?

[lost matrix]

*But keep in mind that ISPs can distribute dynamic IPs

[lost matrix]

This doesnt return anything

[acoustic pendant]

The value of #getItemInUse()

[lost matrix]

Well, because it can be null.
This will only return something if the player is actually using an item right now.
(eating food, drawing back a bow, blocking, etc.)

[acoustic pendant]

Using this on BreakBlockEvent and trying to get if the pickaxe has an specific enchantment, doesn't that method return that?
It is returning null using a pickaxe

[quaint mantle]

but in summary do you mean at all is rare to happen and anybody can't do it ?
do i right understand ?

event.getPlayer().getInventory().getItemInMainHand()

but not in the api

[young knoll]

wacky

[icy monolith]

I have this case opening thing and now i want to add it so that there is a large list of items that can spawn from it, but each item has its own rarity. The chest takes 4 random items based on rarity and spits them out. How do i go about making such system?

[young knoll]

I would look into a weighted random system

[icy monolith]

Are there examples of that algorithm i could look at. Preferably java or kotlin

[young knoll]

https://stackoverflow.com/a/6409791

I still use this old example

[lost matrix]

Yeah i have that as well. Just modified it a little bit.

[icy monolith]

Oh so you have a string of items and a string of weights

Then you sum up all the weights

Then pick a random number between 0 and weight sum

And then the part i dont get is you some how take that and turn it back into the item

[lost matrix]

By a binary tree search. But thats hidden in the TreeMap

[chrome beacon]

oh smile can you check #verified

Im currently using the RangeMap from guava for this instead of a TeeMap

when i have attempted to save itemStack data to the mongodb it was working partially the nbt data didn't go through though, and whenever i searched on google the information to me was irrelevant.

yeah the proper name is Objective. I'd just pass in an instance of one of the existing formats and see what happens lol

just throw in a BlankFormat

[ancient marsh]

i current using: NumberFormat numberFormat = BlankFormat.a;, you mean this?

[tender shard]

idk, you should use mojang mappings instead of the obfuscated names

either StyledFormat.SIDEBAR_DEFAULT or new BlankFormat()

[ancient marsh]

i try

[tender shard]

ofc it depends on how you want it to get displayed. do you even want to show the score number?

or do you just want to use the scores to sort some arbitrary lines of text?

[ancient marsh]

its not importent, that it have numbers

[tender shard]

if you want to show the numbers, use StyledFormat.SIDEBAR_DEFAULT (or create a custom one with new StyledFormat(Component)), otherwise BlankFormat.INSTANCE

[ancient marsh]

i try, but i dont know what i make wronge. I use not the mapped Src.

`` PacketPlayOutScoreboardObjective removePacket = new PacketPlayOutScoreboardObjective(objective, 1);
PacketPlayOutScoreboardObjective createPacket = new PacketPlayOutScoreboardObjective(objective, 0);
PacketPlayOutScoreboardDisplayObjective display = new PacketPlayOutScoreboardDisplayObjective(DisplaySlot.b, objective);

    sendPacket(player, removePacket);
    sendPacket(player, createPacket);
    sendPacket(player, display);``

i dont know what i make here wrong lol

[tender shard]

what's the issue exactly?

and why don't you use remapped 🥲

[ancient marsh]

that i dont see any of the Scoreboard. i used the same code in 1.20.1 but there is any changes of the NMS

[ancient marsh]

mag ich nicht xD

bringt mir auch nichts

lol

[tender shard]

Show the code where you're creating the objective

[ancient marsh]

`` NumberFormat numberFormat = StyledFormat.c;

    ScoreboardObjective objective = scoreboard.a(displayName,
            IScoreboardCriteria.a, IChatBaseComponent.a(chatData.message("%1%§lLobby")),
            IScoreboardCriteria.EnumScoreboardHealthDisplay.a, true, numberFormat);

    PacketPlayOutScoreboardObjective removePacket = new PacketPlayOutScoreboardObjective(objective, 1);
    PacketPlayOutScoreboardObjective createPacket = new PacketPlayOutScoreboardObjective(objective, 0);
    PacketPlayOutScoreboardDisplayObjective display = new PacketPlayOutScoreboardDisplayObjective(DisplaySlot.b, objective);

    sendPacket(player, removePacket);
    sendPacket(player, createPacket);
    sendPacket(player, display);``

public void sendPacket(Player player, Packet<?> packet) { ((CraftPlayer) player).getHandle().c.a(packet); }

Just came here. Why are we using nms for scoreboards?

[tender shard]

no clue

[dry hazel]

so you'd rather use obfuscated names and make your life and lives of the people helping you harder

😵‍💫

[lost matrix]

I think whatever he is doing should be done via the spigot api and not nms in the first place

[ancient marsh]

i know.. But im only using the nms for my Scoreboard. i think its okey for this small packets

[dry hazel]

any particular reason against using the api?

[ancient marsh]

i know what you mean. But im only want using the Tab-Prefixes with the Spigot-API Scoreboard

[ancient marsh]

here, i do the remapped https://i.imgur.com/J9irrTN.png

[sterile flicker]

    public void onPlayerJoin(PlayerJoinEvent event) throws Exception {
        Player p = event.getPlayer();
        for (CraftPlayer ep : manager.getNpcsInChunk(p.getLocation().getChunk().getX(), p.getLocation().getChunk().getZ())) {
            if (ep != null) {
                System.out.println("sended packets");
                manager.showTo(p, ep);
                npcSpawned.put(p, true);
            }
        }
        Npc.injectNetty(p, manager);
    }``` unfortunately, the length of the array manager.getNpcsInChunk is now zero and ```System.out.println("sended packets");
                manager.showTo(p, ep);
                npcSpawned.put(p, true);``` is not executed

by the way, I have implemented the decoder injector, "npc_interact" into the code

he works

but when 2 player join, the NPC disappears

[lost matrix]

You are only sending the NPCs which are currently in the chunk the player is logging in. That makes no sense.
The player needs to receive every loaded npc on the server when he joins.

[frank flicker]

Could anyone check this out if you get the chance? I am trying to change nametag colors in this plugin and I have still not been able to find a solution. The server uses paper 1.18 https://jd.papermc.io/paper/1.18/index.html , and I cant seem to get the nametag color to change no matter what, is it possible? Any help would be greatly appreciated.

[ancient marsh]

[sterile flicker]

it looks like I did something wrong with the injector to process a click on the NPC or sent packets wrong, but now I log on to the server my messages are only visible in the console, I can't open the menu and I get kicked off timed out after a couple of seconds

[inner mulch]

Can i set someones glow effect color without changing any scoreboard stuff?

[young knoll]

no

Glow color is based on team

[echo basalt]

If you're using neznamy's tab you can set it with a placeholder

[inner mulch]

😔

[torn shuttle]

@echo basalt have you actually used the rotation methods you have on your blockdisplaypacketentity class?

[echo basalt]

I believe I used the scaling ones, but not rotation

[torn shuttle]

how the hell are these even meant to work man

I am making a quaternion based on a eulerangle rotation and it just disappears

[echo basalt]

lmfao

you might need interpolation idfk

just look at how craftblockdisplay wraps it

brb buying chicken

[tender shard]

get one for me too

pls

[torn shuttle]

ok I'm getting trolled, no way

[20:14:24 INFO]: INITIALIZATION Left rotation: ( 0.000E+0 0.000E+0 0.000E+0 1.000E+0)
[20:14:24 INFO]: INITIALIZATION Right rotation: ( 0.000E+0 0.000E+0 0.000E+0 1.000E+0)

works

[20:14:24 INFO]: Left rotation: ( 0.000E+0 0.000E+0 0.000E+0 1.000E+0)
[20:14:24 INFO]: Right rotation: ( 0.000E+0 0.000E+0 0.000E+0 1.000E+0)

made the model disappear

am I on drugs

[echo basalt]

Lmao

[tardy delta]

make it NaN

[torn shuttle]

actually it flips to 0 0 0 0 a couple of ticks later so that might be it?

[dusky pollen]

I've come with another question. Is there some type of registry for namespaced keys? I'm currently just using the values from the Material enum, but that feels wrong.

[young knoll]

hmm?

Material has a getKey

[dusky pollen]

I'll look into it, thanks.

That works perfectly, thanks @young knoll ❤️

[ancient marsh]

do any know what i put in in PacketPlayOutScoreboardScore?

the last 3, i know what i know what i put it in

[lost matrix]

Use mojang mappings pls

[ancient marsh]

can you make me a picture what i must have in them?

[cedar flint]

What is the best way to add a fake enchantment glint to items without effecting the item in any other way?

[zinc moat]

can someone explain nms like really simple?

[lost matrix]

nms is short for a package name net.minecraft.server
Its basically the code mojang wrote for creating a minecraft server.

Thats all.

[zinc moat]

oh

that is really simple

[lost matrix]

But people didnt want to use mojangs code (as it changes a lot)
So they created bukkit (which keeps the same code "visible" for developers)
Bukkit/Spigot makes sure that what you are writing once, will work for all the nms versions.
nms -> Changes every version
spigot -> Should rarely change

The idea was to write code once and make it work for the future without updating

[zinc moat]

oh

Alrigth thanks

Didnt know that

[lost matrix]

Thats why if you write a 1.8 plugin, it will work all the way to 1.20 (mostly)

[zinc moat]

does that also work backwards?

[lost matrix]

Not really because Spigot constantly adds new features to their api, and we cant really add those features to older versions

[zinc moat]

Makes sense

[lost matrix]

But we encourage you to use the latest version for your development and server

[zinc moat]

also whats the difference between jdk 1.8 and jdk 17 some people say to use 1.8 jdk

[next plume]

Unless you're writing plugins for old versions of Minecraft, you should use 17.

[lost matrix]

1.8 is really old at this point

[lost matrix]

^

[zinc moat]

oh alrigth

Thanks

[echo basalt]

I gotta make a friend system

p sure past conversations here recommended using some sort of graph

[inner mulch]

yes

conclube recommended it to me

[echo basalt]

how am I gonna do this to not completely break cross-proxy

gotta add a bunch of packet wizardry

[lost matrix]

[inner mulch]

wait was it you ?

im sorry

[inner mulch]

redis?

[echo basalt]

hm

that's one of the solutions

store all the online player friend data on redis

but then if a guy accepts a friend request from an offline player I gotta load it from the db

eh whatever not that complex

[inner mulch]

yes, but you could also just add the friend to the offline player to the db and add the friend in memory to the other one?

[echo basalt]

my original idea was that each proxy would have data for their online players and I'd add a bunch of packets so the proxies talk to each other

be like "ayo this the new data"

and do like 5 trillion checks

[inner mulch]

wasnt this what we talked about 1 week ago?

[echo basalt]

not exactly no

But then imma have friend menus and only the proxies have data context

hm

Should I make a friend service 🤔

[inner mulch]

i think redis is the best solution if you have that many servers, smile told me about having 1 master server with the data and the rest are relying on the master

[echo basalt]

I think the solution is just redis & persistence

bunch of interface magic

Maybe I toss it all on the spigot module and call it a day

[lost matrix]

Or you simply only edit your data in the Database/Redis and keep a read-only view.
I have an auto synchronized collection for that.

Write:

1. Write <K, V> to local map
2. Write <K, V> to redis
3. Send <K> on a redis topic to notify update
4. Every subscriber loads <K, V> into local map from redis

Read:

1. Read from local map

Synchronized Compute (for currency etc):

1. Ack lock from Redis
2. Read <K, V> from Redis
3. Predicate -> Compute on <V>
4. Write modified <V> to Redis
5. Release lock
6. Send <K> on a redis topic to notify update
7. Every subscriber loads <K, V> into local map from redis

This way im assuring a 100% consistent data state with an eventually-consistent read-only cache on multiple instances.

[echo basalt]

Hm

I'm still thinking of using redis but I also gotta fetch friend data from mysql

don't think mongo's set up

[inner mulch]

mongo < sql

[lost matrix]

*>

[inner mulch]

?

[echo basalt]

mongo's nicer

[inner mulch]

why's that?

[echo basalt]

but I can't use it here

[lost matrix]

I like mongo because i will never have to write a schema or any queries ever.
Back the Codec with Gson and boom, store everything without having to write a serializer.

[echo basalt]

I also don't need the "local caching" as it adds a bunch weird complexity given I'll also need proxy logic for like

getting what server your friends are on type deal

[lost matrix]

I literally wrote this

[echo basalt]

so I don't mind just like

having 2 redis caches and fetching a read only snapshot every time I mess with the data

[lost matrix]

Use MongoDB like a Map for anything

[echo basalt]

This has always bitten me in the ass

[inner mulch]

schema's are nice because they ensure you dont put anything where it doesnt belong

[echo basalt]

sometimes your data doesn't have a fixed schema

But yeah as for gson in mongo the problem is like

weird generics

For example at a server I worked for I made a settings system that supported complex types

And I couldn't just yeet generic setting values because I needed context of how I'd read it

And adding the class name to every value just adds overhead

It also gave me weird issues if I were to change the class spec

So I just went back to the classy ways and wrote codecs
