thanks!!

[valid burrow]

wtf is gpt dong

it doesnt make sense

its stupid

[sterile token]

4.5 works perfect

[sterile token]

getOptions()

wait wait

[valid burrow]

where

[sterile token]

that not a serializer

[valid burrow]

i know

[sterile token]

serializers looks like

[valid burrow]

serializer is in a differnt class

i just told it to make my class work with the sirializer and it gave me this

[sterile token]

// example in pseudo code
class CustomItem implements ConfigurationSerialization {

  public CustomItem(Map<String, Object> data) {

  }

  public Map<String, Object> serialize() {
    Map<String, Object> data = Maps.newHashMap<>();
    
    return data;
  }

}

List<CustomItem> items = Lists.newArrayList<>(); // Items repository, can you either Lists or Maps
// pd: If you working with map, you should either saves the keySet() or values() 

void reload() {
  for (CustomItem item : (CustomItem) getConfig().getList("any-path", new ArrayList<>())) items.add(items);
}

void save() {
  getConfig().set("any-path", this.items);
  getConfig().save8);
}

Thats what i use i have implemented in my kit preview

If you dont add the default in the getList(), them if your any-path list is empty will be an NPE

@valid burrow i hope it helps you, if need something let me know please

[storm crystal]

whats the main difference in:
make db connection -> do stuff once -> close connection <= and repeat for each one thing/action
make db connection on start -> do stuff continuously -> close connection on disable <= only once per plugin disable/enable

[young knoll]

You don’t make and open a new connection constantly

[sterile token]

yeah

you just maintain the connetion opened

Because connection re-opening is an intensive operation

[storm crystal]

https://cdn.discordapp.com/emojis/588072223529631763.webp?size=48&name=think_FB&quality=lossless

interesting

so guy from yt tutorial made huge mistake then

[sterile token]

yeah seems weird but has its fundaments

[storm crystal]

cuz he told to keep making new connections and closing them

[sterile token]

most video coding doesnt have good programming things

[storm crystal]

so if I want to open and close it on server enable/disable i dont really need to make any utility methods for disabling / enabling in db manager utility class, yeah?

[sterile token]

atleast minecraft ones

[sterile token]

what?

[storm crystal]

lets say I want to make utility class for db management

I dont really need to make methods for making and closing connection if Im gonna do it just once on plugin enable or disable

[sterile token]

well, in my case i do a class manager for the db where i declare my mongo collections, opening and closing connection. And also catching exceptions

[storm crystal]

do I get that right?

declare mongo collections is what? making dbs?

[sterile token]

Then each repository manager which hand a specific data collection

[sterile token]

oh you use SQL right?

[storm crystal]

I will most likely

[sterile token]

Collections is the same as tables from sql

they are for agrouping data things, they allow to separate the things

[storm crystal]

well at first I want to add them by hand for stuff like custom items

[sterile token]

because you dont mess player data with mini game data for example, there you use different tables or collections depending the db engine you use

[storm crystal]

stuff like player stats would be changed or created on player's first join automatically

[sterile token]

yeay what i do is the next

For big problems i use a mix of persistent db (Mongo or Mysql) + cache database (Most of time, i use Redis here), because each data loading all time is recursively intesive too

But for smalls plugins, you can catch data using caffeine for exampke

[storm crystal]

https://cdn.discordapp.com/emojis/1100416057426059315.webp?size=48&name=PeepoDented&quality=lossless

may I ask what catching data is

[sterile token]

Player joins:

Ask to cache if the data exists, if not exists in cache ask to database. If database, doesnt have any data you create the player data in the cache and finally inser the player data to database

[wet breach]

if you have mysql why use redis for cache when mysql can cache also?

[sterile token]

no ide, i didnt experiment huge things with Mysql im not fan of SQL dbs

[wet breach]

ah

[sterile token]

sorry if i sound inexpert there

[storm crystal]

why should I do cache

like cant I just read stuff from db

[sterile token]

cache allows to keep data in memory, not asking all time the db

[storm crystal]

I assume you need to make your own cache maker methods by hand?

[sterile token]

because each data asked and returned from db is more than intensive than a connection opening or closing at the same time

[eternal oxide]

db access is VERY slow

[sterile token]

you either play around simple things a maps, arrays

But proper caches is for example Caffeine and there some more

[storm crystal]

okay what if I want to edit db

do I just edit cache

[eternal oxide]

cache is anything that holds the data in memory, a Map

[sterile token]

You dont directly work over the db, you update cache

also when always using db every data fetch must be done async. Because mc has only 1 thread, so it blokcs the server operations until the data is retuned from db

[storm crystal]

okay im confused

about

db and cache relation

[sterile token]

were you confused i can help you

right give 1m i explain

[eternal oxide]

Any data you have in memory is "cached data"

[sterile token]

Cache is temporal data in memory, what ever you store tho

A variable is cached data, because its keep inside the memory (RAM talking about pcs)

So what a cache does, is mantain data in memory, but what happen if server goes down? Well data is losted

[wet breach]

if its on some other host, possibly, but if its on the same host no its not slow at all especially if you are using unix sockets

[eternal oxide]

yes it is

[sterile token]

dont all use unix sockets for dbs connection?

[wet breach]

no most use TCP

[eternal oxide]

even if on the same host it's a magnitude slower than accessing memory

[wet breach]

yes but redis is not memory only

[storm crystal]

okay so cache is like screenshot of current data state yeah?

[wet breach]

you still have to communicate with redis

also mysql just like redis can store in pure memory too

[slender elbow]

oh my god frostalf is actually speaking truths this time around

so good

[eternal oxide]

mostly

[storm crystal]

okay so I have cached data and db, how do I edit stuff now?

since I get how to read it, from cache

[eternal oxide]

you edit cache

[wet breach]

so, to say DB access is slow is not true especially when MySQL is quite capable of handling literally millions of accesses without you noticing any slow downs. Most people who notice issues is because they actually don't know how to setup a DB like mysql IE, their configs are not using ideal values

[storm crystal]

and when I close server cache gets updated to database?

I mean I should make it like that?

[sterile token]

@storm crystal

Basically to summarize:

Cached data refers to any type of data that is stored in memory to be used at some point in time. This cached data is of a non-persistent type, that is to say that if you close your program it will be lost.

On the other hand, databases are known to be persistent storage. That is to say, they always store the data that you send or delete, if you ask them to do so.

Is it more or less clear?

sorry, it didnt copy paste

[eternal oxide]

you push your cache data to your db

[storm crystal]

it is

okay lets say

[wet breach]

it is probably more accurate to say cache data is readily accessible data. Doesn't have to be in memory only although this is the most common type people refer too

[storm crystal]

that I want to store this into a database

how would I cache this?

Map of arraylists that would have maps?

[wet breach]

easiest way in Java without external applications, is to create an objectt map

you would turn that data there, into an object

and keep that object in a map

ideally it would at some point save back to the persistent storage if there is changes to it

[storm crystal]

is it very bad of an idea to make method that would save cache into db during server uptime?

[wet breach]

there is various ways of implementing when you want to save the ddata

you can save it only when it changes, you can do periodically

or even at shutdown

or do all of those

[sterile token]

@storm crystal

What is done is to do the following, when a user connects, his information is searched in cache.

If it exists in cache, it proceeds with the rest of the logic. For example show a message in the chat that such a player with x rank entered the server.

Otherwise (if it does not exist in cache), it will query the database to see if its record exists. If it exists, it will put it in the cache until he disconnects or is kicked.

If it does not exist in any of the sides, it proceeds to create its cache and proceeds with the other actions. Asynchronously, its insertion in the database is generated.

Once the player is disconnected or expelled, the cache sends this information to the database. And leave that information a while longer in case he reconnects.

In case of updating, it works on the cache information in case it is a very important change, it sends it to the db immediately. Of course, from time to time the cache requests to the database the information to keep the information updated.

I think i more or less explained the base i could be wrong ofc. If someone else disagrees let me know please so we all learn more 💪 💪

[storm crystal]

so I could make a method that would take into input wanted variable (like let's say Player's rank) in cache, and if it doesnt exist it would make query to database to find such variable and return the value?

[sterile token]

yeah!! exactly

in case it doesnt exists in the db, the rank or player data will be created in the cache

But yeah you more or less getting the idea

[storm crystal]

like taken from standard template of a newly joined player?

[sterile token]

i cant understand that last message

i cant translate it sorry tho

[storm crystal]

like if I had formatting style in chat of "[Lvl] <Player>: Message" and if player joins and there is no Lvl of that player in both cache and db query then it would just create default equivalent which would be Lvl.1 under that player's UUID to use

[sterile token]

sorry for not answering fast but im wrriting an essay while helping for school hhehe

[storm crystal]

fair im patient

[sterile token]

more or less esactly that

Let me explain as a user and custom options right?

DuskTaler conenct the server for firs ttime, data is asked to cache doesnt exists? true, will ask to database. Exists? no well so create a custom object for the player in the cache

Player chats, does he has on join chat disabled by default? We check it in his object created before, so far it will be true because its a new player. In case he has already played before it wont be true, it will be the value returned from cached data

Do you understand more or less?

[storm crystal]

so that how would an example method to grab data look like?

[sterile token]

seen from the top yes

will have some modifications more fully accurate

[storm crystal]

well yeah operations on Maps and Objects but that's kinda semantics

[sterile token]

Data will be first returned to cache, then grabbed from there data you will use

But fully accurate your example you fullly understand it hehehe

[storm crystal]

to ensure that it would be kept up to date?

[sterile token]

practice makes you better

[sterile token]

in my case for ensuring that right? I just load and save data on db when player joins, left or get kicked from server
And every some amoutn of time in case server goes down, you will have less data losses

[storm crystal]

so on player leave I'd take this player and return his currently edited data to main cache that'd get saved to plugin to ensure that it wouldnt be lost?

like in case of heavy traffic or something

[sterile token]

1m i wil ltranslate that

[storm crystal]

okay

is English not your primary language?

[sterile token]

yeah, i talk spanish nativly in case you dont understand me thats the reason

I try to do my best for getting understand haha

[storm crystal]

No problemo xd

[sterile token]

Not sure what you tried to asked on top, but what i understand. Is that if the user disconenct the cached data is saved to the db and stays in the cache for some time. Why still in cache? Because player can reconnect usually went your conenction goes down for some seconds

[storm crystal]

well save player data to cache when they leave to ensure that less data will be lost ye?

[sterile token]

not in the cache itself, mainly in the database

[storm crystal]

oh okay

[sterile token]

because cache contains temporal data

database is what persist them, for not loosing them when the mc server or app goes down

[storm crystal]

so it would be:
player leaves -> his cache is added to database -> cache is reloaded

?

[storm crystal]

temporary

temporal is something else

[sterile token]

oh right

yeah im no the best but you get it heheh

also the cached data is saved to database every x time

[storm crystal]

well they are kinda synonyms I get what you mean

Id use temporary when I want to say that something is not permament

because temporal is in relation to eternity which is kinda abstract

and not many people know temporal

[sterile token]

perfect, i had to go but more or less you understand the logic

If you want them i can help you more about this

[storm crystal]

like Scheduler?

[sterile token]

yeah exactly

Remember this

always when working with dbs calls ASYNC operations

[storm crystal]

ill work with it tommorow cuz its 2 am rn

but ill make notes on theory

[storm crystal]

yeah cuz mc works in 1 thread so it could clog server operations

[sterile token]

its perfect best wishes and good night my mate. Just tag me for any other help

[sterile token]

exactly you already get it hehe

[molten hearth]

mhh im having a bit of an issue, i need a custom block placement system but of course if i just set a block at a location it might include the player, but this has many variables so is there like idk a utility method that checks if a player shouldnt be able to place a block at a location because it intersects with the player

[young knoll]

You can easily check if the bounds of a block intersect the player

Or any entity for that matter

Create a bounding box for the block and then check if it intersects the players bounding box

[molten hearth]

yeah im doing that

but its returning false

lol

when the player is standing right in it

Block block = event.getClickedBlock();
BlockFace clickedDirection = event.getBlockFace();


Location newBlockLocation = block.getLocation().clone().add(clickedDirection.getDirection());
Block newBlock = block.getWorld().getBlockAt(newBlockLocation);
BoundingBox blockBoundingBox = newBlock.getBoundingBox();
if(blockBoundingBox.overlaps(event.getPlayer().getBoundingBox()) || event.getPlayer().getBoundingBox().overlaps(blockBoundingBox)) { // always false
                    return;
}```

[quaint mantle]

someone help me

[remote swallow]

?ask

[undone axle]

If you have a question, please just ask it. Don't look for staff or topic experts. Don't ask to ask or ask if people are awake or available. Just ask the question to the channel straight out, and wait patiently for a reply. Make sure you use the right channel regarding the topic of your question. Create a thread in case the channel is already in use!

[quaint mantle]

i need help with setting up a server setup

[young knoll]

Block#getBoundingBox depends on the type of the block

Air probably returns a box with 0 size

Use BoundingBox.of(block)

[crimson mason]

can someone rq just help with a custom recipie plugin, i got the code but i dont know how to actually give the player the custom item.

[quaint mantle]

can someone help me with luck perms

[drowsy helm]

wdym by give?

if its registered they should be able to craft it without any additional code

[quaint mantle]

What is mirroring my console output? So many commands they duplicate, a player types one command it duplicates in the console and is very hard to keep up with.

[warm pine]

How do i make my plugin support multiple minecraft versions?

[quaint mantle]

What is mirroring my console?

[grand flint]

#help-server

[grand flint]

using methods that all versions u want support

[grand flint]

maybe u have 2 processes running somehow?

did u restart

[quaint mantle]

What processes exist is it a plugin?

[rotund ravine]

Try removing plugins

[quaint mantle]

What processes exist on a server

ok

I will

[grand flint]

ur server

is a process

[quaint mantle]

Even BuycraftX fetches twice.

[grand flint]

ok?

delete ur plugins till it doesnt happen

[quaint mantle]

Delete em?!

[grand flint]

u literally just said ok to that

[quaint mantle]

oh and messages send twice

what plugin would do that

[grand flint]

BRO

HOW CAN WE KNOW??

did u restart ur server

remove ur plugins one by one till it stops

[quaint mantle]

oh you were talking restart my server?

[grand flint]

???????????

[quaint mantle]

no you just use plugmanx

you disable them slowly

[grand flint]

ok

if u know

why are u asking

[warm pine]

I have methods that support most, but I think it is with the API version or Java version

[quaint mantle]

So i deleted all my plugins and the problem still continues

[grand flint]

java is backward compatible

[grand flint]

thats ur problem

so ur telling me u have 0 plugins?

go ask minehut idk

did you restart ur server yet?

probs some minehut misconfiguration shit

[quaint mantle]

I t hoguht it was only frontward compatable

wtf

jk

[warm pine]

What about the API?

[grand flint]

idek what the api version is for lmao wait for someone else

[bitter rune]

whats a better program than vs code for c sharp?

im having a lot of issues; after an hour messing with chocolatey, then finding out i need to patch it to have old commands back to install scriptcs ... now its just bad

[near night]

just base vs

vs code is pain for c#

vs code is pain for java

vs code is pain.

[bitter rune]

just c worked great

[near night]

yeah for c, c++, js/ts, and go it works

[quiet ice]

What even is forwards compatibility?

Isn't that just future-proofing?

[wet breach]

Bukkit/spigot plugins are a good example of being forward compatible

[shadow night]

Isn't that what python doesn't have

[wet breach]

It just means to an extent it should work in later versions

[quiet ice]

So future-proofing basically

[molten hearth]

what is the modern fancy way of achieving custom breaking times for blocks in 1.20+

[quiet ice]

But that basically also implies backwards compatibility

So basically either term in nonsense

[molten hearth]

(disregarding compatibility for older clients)

[shadow night]

Backwards compatibility for the future

[wet breach]

Well backwards compatibility means a plugin built for a new version should also work for a old version

Which is obviously not the case

[quiet ice]

Yup

[shadow night]

I personally support versions down to beta 1.7.3!

Jk

[wet breach]

That would be impressive

[quiet ice]

Whatever

[shadow night]

And impossible, unless seperate jars for versions or some magic

[wet breach]

It isnt impossible per say, just your jar size would be a bit hefty with mostly compatibility code more then anything lol

[shadow night]

Beta 1.7.3 bukkit even does events differently than modern bukkit

The classic class with empty methods

[wet breach]

Doesnt mean you cant have two different classes for events depending on version

[shadow night]

Yeah

I never did that so idk how

You'd also have to register them in seperate ways, soo

[wet breach]

Easiest way is with an enum manager

[shadow night]

A what

[wet breach]

You use enums to invoke the appropriate class needed. You can make enums hold the value of classes

So its called an enum manager

[shadow night]

Hmm

[wet breach]

I used to have a good example of it

Maybe i can create a new one

[shadow night]

Bukkit changed so much

[wet breach]

    Y_TYPE(1) {
        @Override
        public X createInstance() {
            return new Y();
        }
    }, Z_TYPE(2) {
        @Override
        public X createInstance() {
            return new Z();
        }
    };```

[shadow night]

Hmm

[wet breach]

That is one way here is another

   Y_TYPE(1, Y.class), Z_TYPE(2, Z.class);
   int id;
   Class c;
   public Type(int id, Class c) { this.id = id; this.c = c; }
   public static X createInstance() throws Exception {
      return c.newInstance();
   }```

The first way is more ideal as no exceptions

But as you can see enums can hold classes as a value lol

[shadow night]

I did not know that lol

That's actually pretty promising

[molten hearth]

right so actually another issue im having is detecting when a client is breaking a block during a PlayerInteractEvent

[wet breach]

There is a break event

Or start break animation thing

[molten hearth]

cancelling PlayerInteractEvent leads to the break event not firing

[wet breach]

Ah

[molten hearth]

which is where im having an issue lol, I need to cancel the interact because i implement custom logic when the block is left clicked (which conflicts with vanilla mechanics), but also i need to keep vanilla breaking mechanics

[wet breach]

Might have to use reflection

To get the data that isnt given via api

[molten hearth]

could be but im not sure what data im exactly looking for or from which classes tbh

[wet breach]

Well the client reports when player starts breaking a block

So that means where interact is called the data for such should also be present

[wet breach]

Now you know something new enum manager lol have fun with that

[wet breach]

Also an enum can have more then one class for value too

So you could just have enum of version, each version contains the appropriate class values

[shadow night]

I gotta do that fr

[tacit thistle]

you can also just use a Supplier instead of overriding a method for each entry

[wet breach]

Depends which way you want to do it but yeah. Here is example of using supplier method

enum Type {
    Y_TYPE(1, X::new), Z_TYPE(2, Y::new);

    private int id;
    private Supplier<X> supplier;

    private Type(int id, Supplier<X> supplier) {
        this.id = id;
        this.supplier = supplier;
    }

    public X createInstance() {
        return supplier.get();
    }
}```

[ivory sleet]

Its a shame we can’t have generic type params on enums

[wet breach]

What do you mean?

[ivory sleet]

enum SomeEnum<T>

T would be illegal

[wet breach]

Oh right would have to change it to have a normal class for that

Instead of enum it would be
public Type(int id, Class<? extends X> c) { this.id = id; this.c = c; }

[ivory sleet]

Yeah, I suppose one could use a sealed class or sth right, to make it enumish

But yeaa :)

[slate tinsel]

Can I make a spigotmc resource private? So I can only see it?

[candid galleon]

why would you post it then

[wet breach]

Sure, report it to have it removed lol

[slate tinsel]

So meant like making a "tiktok" private. In this case I want to delete a resource but I also want to save it for myself in case I want to build on it in the future or something instead of deleting it completely

[wary harness]

is it possible to save whole HashSet to yml file

I got HashSet which contanis few locations per chunk

and now trying to save it but file ends up empty

[wet breach]

What is the problem with just leaving it as it is?

I have a defunct resource currently that i havent touched for a few years now

[chrome beacon]

same

[wet breach]

I am free to update it at anytime and for the mc versions it still works for those people can still download it if they want

There is no advantage or different features you obtain if it could be private

Just ignore the resource and leave it there. Come back to it when ever

[slate tinsel]

okey

[wet breach]

You have no obligation to respond to comments on it either lol

[slate tinsel]

sorry 😔

[bitter rune]

You're trying to save every single block in every single chunk in a .yml file? If that's the intention I suggest a database that's way to much information for a .yml

[drowsy helm]

Doesnt that defeat the purpose of an enum

[ivory sleet]

Probably yeah lol

I mean there are enum semantics where its allowed in other languages

[drowsy helm]

Well ig an enum is just a fancy class lol cant see many usecases where a generic would be useful though?

[ivory sleet]

I mean it depends on the approach u’re taking

Like in the case of rust’s Option and Result enum, having type constructors is absolutely life saving

[inner mulch]

Is it possible to change the nametag of a player to a color gradient via packets?

(or other methods?)

[ivory sleet]

Nametag?

Like the name above their head?

Or in tab?

(Or both?)

[inner mulch]

Above head

@ivory sleet sorry for my late response

[drowsy helm]

Dont think overhead nametag can be coloured

You can do a team name though

Definitely ways to spoof it

[inner mulch]

Ive Seen Other servers with this Feature, but i dont know how they do it

[wet breach]

Have you tried display entities?

Could also use an armor stand as well

[opal saffron]

Hi
I want to display several unicode characters, but some of them (those whose charcount is 2) are displayed separately.
e.g. \u26CF which is pick emoji displays correct, as ⛏ but
\uD83D\uDD25 which is fire emoji displays as ��.
How could I make it display as 🔥?

[knotty aspen]

they simply might not be part of the font the client uses

so you would need a resourcepack with your own font that includes them

[opal saffron]

no, minecraft displays it correclty

but not from plugin

[wet breach]

Try \u1F525 instead

[opal saffron]

intellij says its wrong, but ill try anyway

[wet breach]

Not sure why intellij will report anything with unicode characters lmao

There isnt really a wrong character code except if you go outside the bounds

[opal saffron]

yup

[slender elbow]

yeah that is not a single character as far as the jls sees it

[opal saffron]

ὒ is \u1F52 and 5 just stays

[slender elbow]

it'll be \u1f52 as a single escape and separately the character '5'

[wet breach]

Weird it does that since that is the official unicode point

[slender elbow]

what happens if you just.. stick the fire emoji in there

[slender elbow]

¯_(ツ)_/¯

jls only allows up to 4 hex digits after \u

[opal saffron]

intellij translates it to \uD83D\uDD25

[wet breach]

Hmm wonder if you just shoved the raw byte in there instead

[hazy parrot]

Is your encoding set correctly?

[opal saffron]

i have utf-8

[slender elbow]

it should give you the option to "replace unicode escape with character"

alt enter

not that it should be any different but, you never know i suppose

[wet breach]

UTF-8 Encoding:
0xF0 0x9F 0x94 0xA5

The raw encoding of that emoji if you want to try some other methods

[young knoll]

Read it from a txt file

https://cdn.discordapp.com/emojis/1017515898870956154.gif?size=48&name=pepe_laugh&quality=lossless

[wet breach]

Well the other way i was thinking would be to reference the character code point directly

And then have that method just stick in the string its needed in

[slender elbow]

StringBuilder.appendCodePoint(int) :^)

[wet breach]

Try this Character.toString(0x1F525)

@opal saffron

[opal saffron]

same output :(

[wet breach]

Ok i have another

new String(Character.toChars(0x0001F525))

[opal saffron]

still... the same

[wet breach]

Java sure is being stubborn -.-

Character.toString(0xF09F94A5)

If that dont work i will be home in an hour and can find more solutions lol

[opal saffron]

java.lang.IllegalArgumentException: Not a valid Unicode code point: 0xF09F94A5

-_-

[wet breach]

Lol

[slender elbow]

i dunno, just doing sendMessage("\uD83D\uDD25") seems to work fine for me https://i.imgur.com/7zNKwr9.png

make sure you are compiling with utf-8 encoding, in gradle it's options.encoding = "UTF-8" in the compileJava task, idk where you'd specify that on maven

[opal saffron]

i am

[slender elbow]

proof or it didn't happen

[slender elbow]

compile with utf-8

not the running server vm

[slender elbow]

i mean the server should run with that too, that's great, but that's only half the story

[opal saffron]

everywhere i have utf-8

[slender elbow]

how are you compiling your project exactly? what do you click or run to build?

[opal saffron]

running maven package

[slender elbow]

you need to tell maven in the pom.xml about the encoding

google "maven compile with utf-8"

[slender elbow]

no

no

please google

[opal saffron]

i have all of that

[opal saffron]

as i said literally

[slender elbow]

do you have the compiler and resources plugins applied?

[opal saffron]

yes

[slender elbow]

yeah so

i believe the kids these days call this a skill issue

runs

[opal saffron]

ehhh

[arctic shuttle]

how would I disable putting an item in ANY CONTAINERS AT ALL? like I know how to disable from taking out but not putting in

[young knoll]

Cancel click event if clicked inventory is a container inv

[arctic shuttle]

isn't that taking it out tho? I want to stop from putting it in

[young knoll]

Click event is fired for both

[arctic shuttle]

is there any way to apply it to ally inventories except the players main one?

[eternal oxide]

you will never account for every way to prevent transfering

[young knoll]

If the clicked inventory is not a player inventory, cancel it

[eternal oxide]

so many ways, hotkey presses, mouse click, item on cursor clicks, pressing q

[young knoll]

Also if the event is a shift click and the top inventory is not a player inventory, cancel it

[river oracle]

Hoppers too

[young knoll]

True

You would have to prevent dropping or hopper pickup for the item

[eternal oxide]

if you mouse over an empty slot in an inventory and press a hotkey for one of your item slot it will swop the slots but you won;t get an item click for your protected item

[river oracle]

Minecart hoppers io

Which are also weird

[young knoll]

There should be a pickup event for both

[eternal oxide]

The click event will fire in my example, but it's really hard to recognize it's trying to move your specific item

you would also have to detect in the drag event too

[native bramble]

should this events in class work:

[smoky anchor]

Don't use snake_case for your constructor arguments
Why is everything static, when you have constructor.
If you were to create two different objects, with different variables, the second one would override the first one.

im new in programming so i dont really now all what im doing

why is your main class called Main?

it is important?

[undone axle]

https://www.spigotmc.org/threads/why-you-shouldnt-name-your-main-plugin-class-main.493289/

[smoky anchor]

I am struggling to understand what you tried to do

Do you just want to overrite all skeletons ?

[native bramble]

i want to make class or interface or maybe smth else, which will be have and events handlers and my custom mob class

because i will have at least 5 more skeletions, so i dont want to write 5 different classes for every skeleton

where event handlers will be different only in one parameter

so i want to create class which will be have event handler

like i have biomeList, which is biomes in which skeleton will spawn

[dull mango]

don’t make ur spawnSkeleton method static

[smoky anchor]

There's much more wrong with what they tried to do

[native bramble]

now i have interface

[dull mango]

Auf cause

[native bramble]

SkeletonHandler

which extend Listener

[smoky anchor]

I don't see why you'd need interface

[rotund ravine]

To interface duuh

[dull mango]

Do u know what an interface is

[native bramble]

interface is like template

smth like this

public interface SkeletonHandler extends Listener {

    void spawnSkeleton(Location location);

    boolean isSkeleton(Entity entity);

    @EventHandler
    void onArrowHit(EntityShootBowEvent e);

    @EventHandler
    void onEntitySpawn(EntitySpawnEvent e);
}

[rotund ravine]

Lol

[dull mango]

Thats false

[smoky anchor]

Don't think this is how you would do the events.

[dull mango]

And ur code is also not working

Why does ur interface extends Listener

[native bramble]

ohh

[smoky anchor]

so they have access to the events

[rotund ravine]

But

[native bramble]

listen pls

[rotund ravine]

No

[native bramble]

i have two skeletons: desert and overgrown(only for now, in future it will be more than 5 skeletons)

and i want to create the same events for first and for second, which will be different only in one List<>

[dull mango]

Use abstracts

[native bramble]

abstract class?

[smoky anchor]

I think what you would want is: have a map of your abstract skeletons - the skeleton type in PDC -> AbstractSkeleton instance
then have one listener class and you would delegate the events to each skeleton based on the type
So you register the listeners only once and can actually use the variables in the skeleton classes

[rotund ravine]

Default interface methods

[native bramble]

yeah

not registering million of classes in main class

[smoky anchor]

No need to use static anywhere too

Also, rename your Main class

[native bramble]

okay, i will read about what is static and when use it

ok

its ok to rename in project name?

[rotund ravine]

?static

[rotund ravine]

Depends

[smoky anchor]

#help-development message

[smoky anchor]

Probably good resource for the static

[native bramble]

ty

so i need to create abstract class?

[dull mango]

Yes

[smoky anchor]

But anyways, I think you're doing good job already, seeing you have guard clauses
Def. better than some ppl who come here and

[river oracle]

Arrow pattern best pattern

[dull mango]

abstract class CustomSkeleton
class Skeleton1 extends CustomSkeleton
…

[native bramble]

but then i will have two classes: OvergrownSkeleton and DesertSkeleton, yes?

[dull mango]

yes, that was just an example

[native bramble]

and i need to register this two classes?

[rotund ravine]

What did bing change

[smoky anchor]

If you do this, the no

[native bramble]

ohh, really

[rotund ravine]

Illusion Search Index - Static (aboose)

Static is a keyword in Java that modifies the behavior of variables and methods. To understand static, we need to review some basic concepts of object-oriented programming.

Classes and Objects

A class is a blueprint that defines the structure and behavior of an object. A class specifies what fields (variables) and methods (functions) an object will have, and how they will interact with each other.

An object is an instance of a class, created with the new keyword and a constructor. A constructor is a special method that initializes the object with some initial values or logic. For example, we can use a constructor to inject some dependencies into the object.

An object is a bundle of data and behavior that follows the structure defined by the class. We can think of an object as a box or a package that contains some information and actions. The information is stored in the fields, and the actions are performed by the methods.

When we pass an object as a parameter to a method, we are actually passing a reference to the object, not the object itself. A reference is a pointer that indicates where the object is located in memory. This way, we can avoid copying the whole object, which would be inefficient and wasteful. This is also known as "pass by reference".

Static Variables and Methods

Static is a keyword that indicates that a variable or a method belongs to the class, not to a specific object. A static variable or method is allocated in memory only once, and can be accessed by any object of the class, or even without an object.

A static variable is also known as a class variable, because it is shared by all instances of the class. A static variable is initialized when the class is loaded, and remains in memory until the program ends. A static variable is not affected by the garbage collector, which is a mechanism that frees up memory by deleting unused objects.

A static method is also known as a class method, because it can be invoked by the class name, without creating an object. A static method can only access static variables and other static methods, because it does not have a reference to a specific object. A static method is useful for performing general operations that do not depend on the state of an object.

Static variables and methods are designed for constants and utility classes, which are classes that provide some common functionality without creating objects. Static variables and methods should be used sparingly, because they can cause problems such as memory leaks, concurrency issues, and tight coupling.

The only exception to this rule is the singleton pattern, which is a way of ensuring that only one instance of a class exists in the program. A singleton class uses a private constructor and a static variable to store the unique instance, and a static method to return it. A singleton class is useful for managing global resources or state, but it should be used with caution, because it can introduce hidden dependencies and make testing difficult.

TL;DR - Valid usage of static in:

• Constants
• Utility classes
• Singletons (when dependency injection is impossible)

Examples

Here is an example of a utility class, with a constant:

public final class MyUtilityClass { // final to prevent inheritance

    private static final int NUMBER_OFFSET = 100; // constant value, permanent
    
    private MyUtilityClass() { // Private constructor to prevent initialization
    
    }
    
    public static int offsetNumber(int original) {
        return NUMBER_OFFSET + original; // static method accessing static variable
    }
}

Here is an example of a lazy singleton (lazy means it is only initialized when needed):

public class MySingleton {

    private static MySingleton INSTANCE = null; // static variable to store the instance
    
    public static MySingleton getInstance() { // static method to return the instance
        if(INSTANCE == null) { // check if the instance is null
            INSTANCE = new MySingleton(); // create a new instance if null
        }
        
        return INSTANCE; // return the existing or new instance
    }
    
    private MySingleton() { // private constructor to prevent external initialization
        // optional: check for duplicate instances
        if(INSTANCE != null) {
            throw new IllegalStateException("Duplicate instance");
        }
    }
    
    private int currentNumber = 0; // non-static variable to store some state
    
    public int getOffsetNumber() {
        return MyUtilityClass.offsetNumber(currentNumber++); // non-static method accessing static method and non-static variable
    }
}

Here is what NOT to do (unless you're a clown):

public class Circus {

    private static PlayerManager playerManager; // static variable to store a non-constant object
    private static SomeOtherManager someOtherManager; // static variable to store another non-constant object
    private static String status = "broke"; // static variable to store a mutable state
    private static int money = -1; // static variable to store another mutable state
    
    public static PlayerManager getPlayerManager() { // static method to return a non-static object
        return playerManager;
    }
    
    public static int getMoney() { // static method to return a non-static state
        return money;
    }
    
    public static String getStatus() { // static method to return another non-static state
        return status;
    }
    
    public static SomeOtherManager getSomeOtherManager() { // static method to return another non-static object
        return someOtherManager;
    }
}

[smoky anchor]

Ye, you would register just one listener
And create your 5 skeleton instances, each with different parameters

WHY are you reposting this

I think Illusion will be mad

[rotund ravine]

It’s not a repost

[proud badge]

How do I like save a variable of a block, like so the variable wont change even after the block changes

[rotund ravine]

Why?

And what variable?

[proud badge]

Because my event is delayed and sometimes it shows wrong info

[rotund ravine]

??

[smoky anchor]

what is it then

[proud badge]

For example if someone quickly breaks and placed a block it will show the placed block (onblockbreak event)

[rotund ravine]

I told bing to refine and extend it

[rotund ravine]

No?

Get the stuff from the event

[proud badge]

Ok my friend is tripping then idk, ill check logs when im home

[slender elbow]

ur singleton creation is not thread safe :kappa:

[rotund ravine]

Is illusions?

[slender elbow]

where

[rotund ravine]

Z

[rotund ravine]

Here u go. - Bing:

One possible way to make a singleton in Java is to use a static nested class that holds the instance of the singleton class. This way, the instance is created only when the nested class is loaded, which is lazy initialization. The nested class is also thread-safe because the class loading mechanism ensures that only one thread can load a class at a time. Here is an example of how to implement this approach:

public class Singleton {

    // private constructor to prevent instantiation
    private Singleton() {}

    // static nested class that holds the instance
    private static class SingletonHolder {
        // create the instance as a final static field
        private static final Singleton INSTANCE = new Singleton();
    }

    // public static method to get the instance
    public static Singleton getInstance() {
        // return the instance from the nested class
        return SingletonHolder.INSTANCE;
    }
}

This is one of the shortest and thread-safe ways to make a singleton in Java. There are other ways as

[slender elbow]

that is thread safe yeah

[rotund ravine]

Even better

[rotund ravine]

One of the shortest possible and thread-safe ways to make a singleton in Java is to use an enum. This approach has serialization and thread-safety guaranteed by the enum implementation itself, which ensures internally that only the single instance is available, correcting the problems pointed out in the class-based implementation¹. Here is an example of how to use an enum to create a singleton:

public enum Singleton {
    INSTANCE;
    // other fields and methods
}

To access the singleton instance, you can simply use Singleton.INSTANCE. This is also the recommended way of implementing singletons by Joshua Bloch, the author of Effective Java².

for extra points you can do

public class Singleton {

    public static Singleton getInstance() {
        class SingletonHolder {
            static final Singleton INSTANCE = new Singleton();

your phone is weird then lmao

you are not zoomed in are you?

that happened once on my phone where it zoomed in slightly

[rotund ravine]

I am not

Blame ios easy

[wet breach]

ah iphone

[glad prawn]

why does it look so pale?

[wet breach]

figures

[smoky anchor]

if(!isInBiome(skeleton, e.getLocation().getBlock().getBiome())) return;
won't work, gotta continue instead.

[wet breach]

its an iphone

that is why

[native bramble]

oh ty

[smoky anchor]

same for the other loop onArrowHit

[rotund ravine]

Does spawn entity trigger the Spawn Event?

[smoky anchor]

I beleive it does

[native bramble]

i will check

[smoky anchor]

just put a check to see if what is spawning is not your custom skeleton

Anyways, this won't work 'cause you ignore the skeleton types.
Best would be a map "string" -> "type insatnce"
For every event, you'd just get the skeleton type from the entity, get the skeleton instance from the map and use that to do your custom thingies

wait, that is what you're doing

it will work, just can be more efficient

[shadow night]

I had the same issue before, but instead of closing that menu it closed the keyboard making me unable to type

[grim hound]

class in a method

damn

never used those I have no idea on how they behave

anyway, how can I make a gif show itself on a spigot resource that's hosted by imgur?

[rotund ravine]

Try really hard

[shadow night]

100% success rate

[grim hound]

brah

how do others do it then?

[rotund ravine]

Just insert image and put in the direct link?

[grim hound]

it's a gif

[rotund ravine]

What is the link?

[worldly ingot]

Thread safety is for weirdos

[grim hound]

https://i.imgur.com/3U7f7zg.gifv

[rotund ravine]

Yes

Just gotta end in gif which imgur doesn’t

[grim hound]

why the fuq is this so loud

[rotund ravine]

Idk i am not at full volume haha

[grim hound]

then

what do I do?

bruh

why the v tho

oh wait

[wet breach]

its probably to combat their own unique identifier generator

[grim hound]

This imgur stuff is sickkkk

[wet breach]

just remember to check on your images like once a year

[grim hound]

do they auto-delete them?

[wet breach]

at some point yes

its really inconsistent on how long they will last XD

[grim hound]

it

ain't playing

[wet breach]

does spigot even allow gifs?

[grim hound]

they do

I've seen other plugins do it

[grim hound]

also look here

[rotund ravine]

Just cause u can doesn’t mean ur allowed to 🤪

[grim hound]

what the fuq

how did you

[rotund ravine]

Image

[grim hound]

insert it as media?

[rotund ravine]

A gif is an image

[grim hound]

both don't work

[wet breach]

you are using the correct editor in spigot right?

[grim hound]

the gif doesn't play

[grim hound]

what does that even mean?

[rotund ravine]

Wha tlink shadow?

[grim hound]

https://i.imgur.com/x5o8oleb.gif

[wet breach]

there is two different editors for creating the resource page

one is the fancy one

[grim hound]

wait wat

[wet breach]

the other is the manual one

[grim hound]

it ain't playing normally as well

[rotund ravine]

Blame imgur

[wet breach]

https://imgur.com/x5o8oleb.gif

[rotund ravine]

No frostalf

That won’t give him the gif

[wet breach]

I was just testing it

[rotund ravine]

Ahh k

[native bramble]

it working in event

[grim hound]

https://i.imgur.com/x5o8olet.gif

hmm

[rotund ravine]

Use smth else

[grim hound]

bruuuh

[wet breach]

so I went to the link

and imgur is giving it to me as a jpg

[grim hound]

https://i.imgur.com/x5o8ole.gif

I just removed the v at the end

[rotund ravine]

Shouldn’t supply the gif huh

[grim hound]

bruh it works

[wet breach]

I see the issue

[grim hound]

XD

[wet breach]

or the issue before

there was an extra character in the url

[grim hound]

aaaand it stopped working

[wet breach]

https://imgur.com/x5o8ole

[grim hound]

I don't get it

[wet breach]

remove the character just before the extension

not sure why the extra character gets added

[grim hound]

it works in the spigot

edit page

but not on the website itself

[wet breach]

did you clear caches? or tried to

[grim hound]

and the page just crashed

[wet breach]

do a force refresh

[grim hound]

what the fuck

spigot

you son of a-

[wet breach]

just use the manual editor

[grim hound]

you literally work in the editor

[wet breach]

probably because the preview is javascript

which works from your system and not the server

[grim hound]

what manual editor?

ain't tis

a manual editor?

[young knoll]

There is a rich editor and a bb code editor

[grim hound]

how do I access it?

[young knoll]

Wrench in the top right of the input box

[grim hound]

uhh

[worldly ingot]

There's a size limit of like 4.5MB for attachments iirc

gifs tend to exceed that limit very often

[grim hound]

but it's hosted externally

[wet breach]

if you use no compression XD

[worldly ingot]

Doesn't matter. Content is proxied

[grim hound]

mine is 157

[worldly ingot]

Just a tad large

[wet breach]

157mb?

[grim hound]

yep

[wet breach]

compress it -.-

also reduce some of the images in it

[grim hound]

blasphemy

amma be real with you

I have no idea how to compress a gif

[young knoll]

Oh external stuff is proxied

F

[rotund ravine]

Makes sense

[arctic shuttle]

does anyone know how to send action bars my method isn't working

[rotund ravine]

Show

[grim hound]

Player#spigot#sendMessage

and ACTION_BAR for the type

or smthg like that

[arctic shuttle]

yeah thats what I was doing

but I have another idea

[rotund ravine]

Don’t

[wet breach]

how do you not know how to compress it?

o.o

[rotund ravine]

Show code

[grim hound]

I found some websites online

[wet breach]

[grim hound]

I was thinking about the video editor

[grim hound]

what the f-

[rotund ravine]

Looks fine

[grim hound]

needless to say, the video editor wasn't very helpful

I selected a lower frame rate bruh

[wet breach]

something tells me this is larger

[grim hound]

it is

5 times

[whole lintel]

Hello

I have a PlayerInteractEntityEvent listener

[grim hound]

for losing frames

[whole lintel]

that prints out "Entity captured"

and a playerinteract event

[grim hound]

ah wait, it converted it into a mp4 for some reason

[whole lintel]

( if (!event.getAction().equals(Action.RIGHT_CLICK_BLOCK)) return;)

with that

that prints "Entity spawned"

But when i right click an entity

i get both

messages

How is the PlayerInteractEvent running

(with a check for the action) as i said)

[rotund ravine]

?interactevent

[undone axle]

The PlayerInteractEvent may be called once per hand. If you only want code to be executed once, you can check the result of https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/player/PlayerInteractEvent.html#getHand(), then decide functionality.

For example, only executing code if the main hand was used:

@EventHandler
public void onPlayerInteract(PlayerInteractEvent event) {
    if (event.getHand() != EquipmentSlot.HAND) { // * if the hand used is NOT the main hand:
        return; // do not progress past this point  |
    }
    // provide functionality
}

[whole lintel]

Ok? @rotund ravine

[wet breach]

try adding a check if they right clicked air

for the block

if they did, don't do anything

[whole lintel]

I did

oh wait

OH

lemme try that

[wet breach]

I guess that fixed their problem

[rotund ravine]

Yes i suppose so

[wet breach]

they should have been checking for air to begin with

newb mistake

[quaint mantle]

like if a program onjava 16 it could run on virtual threads

😄
'

[whole lintel]

That only fixes it for when there's no solid block behind the entity

[rotund ravine]

?paste

[undone axle]

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

[wet breach]

so check for an entity in front of the block

[whole lintel]

the entity disappears

[wet breach]

o.O

[whole lintel]

in the other PlayerInteractEntity event

that i have

so maybe i know the issue

it's probably because playerinteractevent is called after playerinteractentity

in spigot's code

Not sure though, just a guess

[glossy venture]

nah im pretty sure the threads are backwards compatible, so like new Thread() just creates a new OS thread

which is the old behavior

[ivory sleet]

Yeah or well “platform thread”, u’re completely right

[glossy venture]

ig thats a more appropriate name

is that the official

name in java

official terminology

[ivory sleet]

I wanna say yes cuz I touched those 2 days ago, but unsure lol

[glossy venture]

lmao

native thread also works

[ivory sleet]

Yea

[arctic shuttle]

does anyone know why this isn't working?

[eternal oxide]

The event is cancellable so the item has likely not yet moved

Fetch it from the getPreviousSlot()

[arctic shuttle]

alr

[rotund ravine]

Also don’t do requirenonnull

[upper hazel]

i try create custom block with armorstand but why does it darken if it is inside blocks, how can I change this?

[eternal oxide]

Lastly identify items via PDC tags not their name

[arctic shuttle]

hmm weird still doesn't work

[upper hazel]

don't pay attention to the lack of texture I was too lazy to make 3d textures for testing

Disable gravity and turn em upside down or smth

[upper hazel]

this will not be possible everywhere

i will generate in world

this blocks

[rotund ravine]

Well gl then

[upper hazel]

Is it true that you can make model 3d ItemStack?

i mean like this

but with "textures"

to make it look like a real block

not player head lol

[quiet ice]

Yeah at that point no software is forwards compatible unless it literally does not change

[arctic shuttle]

hey if someone could help it would be epic, it still doesn't work

[rotund ravine]

?notworking

[undone axle]

"Does not working" is a useless statement. Please describe what exactly is not working, what you expect it to do, and what actually happens. If you get any console errors, also ?paste the entire stacktrace.

[rotund ravine]

Post new code too

[clever lantern]

how do i disable animals spawn

through a command

[sterile token]

lmao i just realize this chat turned into a discussion. Why people dont like to first learn java?? instead of trying to code without any knowledge and then getting mad because they are told to learn java first

[clever lantern]

bcs its the hard part

but you have to do it

[upper hazel]

The problem here is not even in java. Before creating any programs, people need to develop the mindset to “easily” switch from java to api

otherwise the api will become "language 2"

[sterile token]

yeah thats totally true too

its what happen to me, i dont have huge knownlgedges about the api itself. But i have more knowledges in plain Java, like good practices, organization, conventions and many others things

[upper hazel]

I personally studied both Java and bukkit api
although I later regretted the decision to make the rtp plugin for half a year🥶

I did it for 5 months

after 2 years refactoring

and now again

[sterile token]

Im in a point where i dont regret about learnt to code plugins. Because i was forced to learnt a coding language, so there i seen i was capable for creatings things on my own. And now im working hard on personal proyects not even related to minecraft itself, mainly market place products. Which they are sell in the real economy of programming and software

[whole lintel]

i think i found a bug

PlayerInteractEvent runs with PlayerInteractEntityEvent if i remove the entity on PlayerInteractEntityEvent

[upper hazel]

demm this tranlation

not can do normal

[sterile token]

what?

[upper hazel]

The translator mistranslated it, I meant I wish I had learned Java first and then only the bukkit api. That's the reason why it took me 6 months to make my first plugin.

[sterile token]

yeah lmao, i was what happened to me. I made the same mistake try to code without first learning Java itself or dedicating more time to plain Java

@whole lintel forget wha ti have said, i was wrongly

can you re-explain what issue you are experimenting?

[whole lintel]

Well

i basically

remove an entity

when a player clicks it

then i print something when the player right clicks a block

and something gets printed when a player right clicks an entity and also when they right click a block

[sterile token]

well, i would have to check the docs

Give me 5 i will check those events and we will realize if its a bug or not

[river oracle]

can you explain what isn't working exactly

[arctic shuttle]

no console errors

[river oracle]

wait

[arctic shuttle]

the action bar

[river oracle]

there is a space in your class name

[arctic shuttle]

no way

[river oracle]

how did that compile

[onyx fjord]

@arctic shuttle what editor are you using

[arctic shuttle]

inteillj

Idea

community

[onyx fjord]

lol

[river oracle]

how did that compile

[arctic shuttle]

how

[river oracle]

the space in the clsas name

[onyx fjord]

it should give you like million warnings

[arctic shuttle]

loll

[river oracle]

it shouldn't compile either

idk what black magic you used to turn that into a jar

[rotund ravine]

He probably didn’t

[arctic shuttle]

ok lemme try now

this time no space

[onyx fjord]

btw avoid nesting

just return early

[arctic shuttle]

ok

[onyx fjord]

by reversing your if statements

[slender elbow]

it makes your code 99% faster if you return early

aye, little white lies never hurt anyone

[young knoll]

It's actualy 100%

[arctic shuttle]

hmm still isn't working

[smoky anchor]

You somehow seemingly managed to compile with a space in a class name, I think your problem is somewhere else tbh

[unkempt peak]

Hey guys, so I've been working on a video player project and I have come up with an optimized block placing method with the help of this blog: https://www.spigotmc.org/threads/methods-for-changing-a-massive-amount-of-blocks-up-to-14m-blocks-s.395868/

The only problem I'm having now is the client can't seem to render the blocks fast enough. When playing the video it only renders the center of the screen most of the time and the rest is just a mess of squares of outdated blocks.

I am using the second method from the blog by updating the block directly from the chunk. I am using nmsWorld.sendBlockUpdated(blockPos, blockState, blockState, 2); to send block updates to the player. Is there a way to send all the blocks at once? Or is there something I can do with the client to get it to render the blocks faster?

Here is the full method for reference: https://paste.md-5.net/bojejisacu.cpp

[smoky anchor]

you can't manipulate how fast the client updates the chunks

[quaint mantle]

public BukkitTask playAnimation(List<TeleportData> teleportDataList, Entity entity) {
        currentIndex = 0;
        int delay = 50;

        BukkitRunnable runnable = new BukkitRunnable() {
            @Override
            public void run() {
                if (currentIndex < teleportDataList.size()) {
                    TeleportData teleportData = teleportDataList.get(currentIndex);
                    entity.teleport(teleportData.toLocation());
                    currentIndex++;

                    // Check if more iterations are needed
                    if (currentIndex >= teleportDataList.size()) {
                        // Animation is complete, cancel the task
                        this.cancel();
                    }
                }
            }
        };

    // Schedule the BukkitRunnable to run repeatedly at the specified interval, then return the runnable
    return runnable.runTaskTimer(FabledCore, delay, 1);
    }```

This playAnimation function sstarts a bukkit runnable, and in another class i need to run the playAnimation method a number of times in a for loop. How can i ensure the for loops awaits for the bukkit runnable to end before proceeding with the next iteration ?

[unkempt peak]

Is it possible to optimize the block updates so the server doesn't have to send every single block individually?

[celest venture]

Hey all, I'm dipping my toes for the first time into plugin development. I'm trying to upgrade an existing abandoned package. However, when I try to run the plugin, the console gives back the following error: JavaPlugin requires org.bukkit.plugin.java.PluginClassLoader

I've been Googling all over, and it seems there can be multiple causes for it. I'm using IntelliJ IDEA with Maven to package the .jar file.

[slender elbow]

OOSAKAAAA

[quaint mantle]

OMGGGGG :333

[unkempt peak]

Can you send your pom?

[smoky anchor]

I am not sure if spigot has a method, but there is a packet for multi-block change

[celest venture]

[unkempt peak]

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

[river oracle]

if you need help with paper should prob use their discord

https://discord.gg/papermc

further paper plugins tend to be incompatable with spigot so running a paper plugin on spigot may cause issues

[pseudo hazel]

you should prefer just creating plugins for paper, perhaps using like the paper lib that some person made

[unkempt peak]

Why are you making a paper plugin instead of spigot?

[pseudo hazel]

so it would still work on spigot servers, but you can get some of teh paper features

[celest venture]

I'm not sure yet if that is the cause, AFAIK I don't even see the dependency being used.

[river oracle]

certain org.bukkit things may be exclusive to paper

[pseudo hazel]

see if its fixed if you switch to spigot

[celest venture]

Thanks all!

[quaint mantle]

can someone help me ? qwq

[pseudo hazel]

why not just use a timer task

[quaint mantle]

would that make the for loop await for the timertask to be over ?

[pseudo hazel]

well you could just have some kinda timer task that stops after some amount of iterations

[quaint mantle]

how could i implement that ?

public void playCinematic(Player p, String cinematicName) {
        ArmorStand armorStand = p.getWorld().spawn(p.getLocation(), ArmorStand.class);
        armorStand.setVisible(false);
        armorStand.setGravity(false);

        p.setGameMode(GameMode.SPECTATOR);

        List<TeleportData>[] cinematicMotionDefinition = cinematicsBundler.getCinematicMotionDefinition(cinematicName);
        if (cinematicMotionDefinition != null) {
            for (int i = 0; i < cinematicMotionDefinition.length; i++) {
                List<TeleportData> keyframeMotions = cinematicMotionDefinition[i];

                if (i == 0) {
                    if (!keyframeMotions.isEmpty()) {
                        TeleportData firstTeleportData = keyframeMotions.get(0);
                        Location firstLocation = firstTeleportData.toLocation();
                        armorStand.teleport(firstLocation);
                        p.teleport(firstLocation);
                        p.setSpectatorTarget(armorStand);
                    }
                }

                // Play the animation for the current keyframe motion
                BukkitTask animationTask = motionProcessor.playAnimation(keyframeMotions, armorStand);

                try {
                    animationTask.getTaskId();
                } catch (InterruptedException | ExecutionException e) {
                    e.printStackTrace();
                }
            }
        }
    }```

this is the method with said for loop

[left pine]

Hello, I wanted to know how I could create a custom block

[dull mango]

what do you mean with custom block?

[left pine]

that you can put as a title above the block or that when interacting with it it does certain things, etc...

[dull mango]

u create a listener for the PlayerInteractEvent. Check if the player is interacting with a block, then check if the player is interacting with your custom block -> add your custom code

[grim hound]

is this how you get the newly held item?

[rotund ravine]

No

?jd-s

[undone axle]

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

[rotund ravine]

Wait yes

Sry i thought about the other event

[grim hound]

good to know

thanks

[dull mango]

for example like this:

    @EventHandler
    public void onPlayerInteract(final PlayerInteractEvent event){
        final Player player = event.getPlayer();
        if(event.getClickedBlock() == null) return;
        final Block block = event.getClickedBlock();
        if(block.hasMetadata("your custom metadata")){
            // ...
        }
    }

[rotund ravine]

Hmm

[grim hound]

mmmmmmmmmmm

[rotund ravine]

Won’t persist btw and i am not sure normal blocks have metadata?

[grim hound]

why is the limit a mere 4.5 mb

[rotund ravine]

Cause

[river oracle]

they have metadata

just not PDC

though metadata doesn't persist

[dull mango]

you can set a custom metadata

[river oracle]

?blockdata

[rotund ravine]

Huh i never knew

[river oracle]

where is mfnalex's library

[rotund ravine]

?custombloxks

[river oracle]

do you want the data to persist?

[rotund ravine]

Not sure

?customblocks

?blockpdc

[undone axle]

Learn about CustomBlockData here:
https://www.spigotmc.org/threads/custom-block-data-persistentdatacontainer-for-blocks.512422/

[river oracle]

if so ^

[dull mango]

the block metadata persist

[rotund ravine]

No

[dull mango]

with FixedMetadataValue

[rotund ravine]

No

[dull mango]

The metadata is only deleted when the block is placed and destroyed again

[rotund ravine]

Or the server reloads or restarts

Or the chunk unloads and loads probably

[grim hound]

Fuck you spigot

it's 1.5 mb

and it's already shit

[lost matrix]

Use an external source 🙂

[grim hound]

Doesn't work 👍

[rotund ravine]

Proxydoxy

[knotty aspen]

I recall the metadata API having some memory leak issues, at least with entity metadata. Would just stick to PDC tbh

[lost matrix]

Not with that attitude

[grim hound]

I'm mad because I've been trying for way too long to do something so easy

[young knoll]

Just use a video

[lost matrix]

Yeah it do be like that sometimes

Just make multiple posts and tell the user to flip between tabs

[serene sigil]

how do i get the import com.mojang.authlib.GameProfile;

is it in nms

[rotund ravine]

Use PlayerProfile
