Movement is client side and trying to stop the velocity that way on the server will just cause problems

[rotund ravine]

Do some math

[twin venture]

hi , question what would be the best way to handle multi profile system for each user so for example :

• Solo , doubles , Ranked , insane , this is 4 diffrent type of the same Mode [skywars]
  what would be the best way to handle the user data for each type ?

i was thinking about making a profile for each type

and just load them all

when user join , and edit it when it required

[grand flint]

just save it all under the same user's stats in the databae

like
username
> ranked

kills
deaths
> solo
kills
deaths

[acoustic stag]

how can i clear banner patterns from a shield? if i have a shield with a banner applied to it, how to get a clean shield?

[rotund ravine]

I mean you can just give them a new shield with the same durability

[acoustic stag]

isn't there a better way?

[rotund ravine]

Probably

[grim hound]

the Info packet on older versions InfoAction.ADD_PLAYER and on newer wersions EnumSet.of(ADD_PLAYER , UPDATE_LIST)

[acoustic stag]

yeah i know how to set a pattern but i want to remove it

[rotund ravine]

Just remove them instead of adding

[acoustic stag]

how

[young knoll]

Oh shields use blockstatemeta

Interesting

[rotund ravine]

[rotund ravine]

It’s a very simple method

[cold pawn]

Did that, and im assuming that setting the PlayerInfoData is still the same, but I get an error saying cannot cast List to EnumSet. And it points to when I’m setting the PlayerInfoData

[grim hound]

???

Whatchu asking?

like

a List is a different structure to an EnumSet

I even told you to do

[grim hound]

so ofc you get an error

[lost matrix]

static import

[grim hound]

variable

[icy beacon]

Is listening to PlayerStatisticIncrementEvent for JUMP increase the best way to detect jumps? Or is there some API I don't know about?

[young knoll]

Pretty much

[icy beacon]

Kk ty

[grim hound]

wait

TabCompleteEvent

is command only?

[grim hound]

yeah I saw that

[icy beacon]

Kk

[grim hound]

but then

is there no event for when someone checks the TAB?

[rotund ravine]

Clientside

[icy beacon]

Do you mean the tablist?

[grim hound]

ohhh that's why the packets are one-time

[grim hound]

yeah

[icy beacon]

Yeah I think that's not sent to the server

Unless there's some peculiar packet

[rotund ravine]

There would be little reason for it to be sent

[grim hound]

is there any event

for tablist manipulation?

[cold pawn]

Yeah I know, I set the EnumSet then the PlayerInfoData but it gives me an error saying cannot cast ArrayList to EnumSet. Heres what I have.

[grim hound]

Enum

Set

Not

Set

and

not

luist

list

just

EnumSet

I have no idea how ProtocolLib works

[glad prawn]

spam 😡

[cold pawn]

😅

[grim hound]

shut up

[icy beacon]

This has never happened before 😮

[cold pawn]

ngl feel kinda slow rn

[icy beacon]

Take a tea break

Stretch a bit

[grim hound]

but 100% Set is not the correct one

either input only the action or only the EnumSet

try both

[cold pawn]

Ok gotcha

[grim hound]

so if I want to hide some players in the tab I have to send the remove packets to everyone?

[icy beacon]

I think so

[grim hound]

mmmm

is there a way to stop the server from sending it in the first place?

except for constant ChannelDuplexHandler monitoring

[young knoll]

ProtocolLib

You can listen for and cancel packets

[grim hound]

so constant monitoring

[young knoll]

yes

[grim hound]

fine

[brazen badge]

Can anyone help me? I would like to create a command that accepts 3 args, player_name time number. I want these args to be passed in an event, and everything I write in the event is executed for a certain amount of time (I use a database). how can I do?

[rotund ravine]

That’s a lot of stuff

That doesn’t really pair together

What is the outcome you want it to do?

[brazen badge]

The important thing is that I understand how to pass the args

[rotund ravine]

Nope

[eternal oxide]

The important thing is you properly explain your end goal. It sounds like you have everything else wrong

[brazen badge]

a mmocore booster

with PlayerExpGainEvent

[eternal oxide]

Explain your end goal. What is it supposed to achieve?

[brazen badge]

I want the exp to be multiplied by the value I wrote in the command and the time I said in the command

[eternal oxide]

all exp?

[brazen badge]

yep

[eternal oxide]

not difficult

[slim gate]

hi

[eternal oxide]

first you need some kind of database (HashMap) to hold the player multiplier data.

then in the exp gain event you read from that database for the player multiplier and do Math

[brazen badge]

but the time?

[eternal oxide]

you create an object which holds the multiplier adn the time

so your Map<UUID, Data>

data can just be a simple Record

public record Data (float multiplier, long time) {}```

[brazen badge]

my problem now, it's not how to save the data. It's how to check the time, if it's done or if it's started

[eternal oxide]

just use System.currentTime

mills, it's a long

using that you can compare teh stored value against the current and see which is larger

[quaint mantle]

Learn about unix timestamps

and math

[twin venture]

Hi iam facing a weird problem

again

what iam doing wrong ,-,?

[eternal oxide]

sw.null

[twin venture]

well its already there in the mysql

why it say its null

[eternal oxide]

null isn;t a table

[twin venture]

i dont have a null anywhere

[hazy parrot]

Show where you make your query

[twin venture]

didn't set any null vlaues

this is where its acctully buged

the bug is from here

mySQLManager.executeUpdate(query, parameters.toArray(new Object[0]));

this line

[twin venture]

wait ik whats wrong

the name was ..

uhhh

oky thanks

[river oracle]

I'm attempting to store a Multiblock structure within a chunk's PDC, I'm questioning what type of key I should use though, the issue with sometihng like a BoundingBox would be the need to reconstruct a bounding box to grab the MultiBlock, I'm hestitant to use a Location because you'd need to store many locations that conforms to the size of the multiblock

[eternal oxide]

if you are storing in a Chunk you don;t need the location, only the x/y/z

[lost matrix]

How do you handle multiblocks which cross chunk borders?

[river oracle]

good point I didn't quite think about, unfortunately I'm still trying to figure out how to store the data at all within PDC

[lost matrix]

They key would be "multi-block-structures" and the value would be a List<MultiblockStructure>
Each structure has a base block and a list of x, y and z values, pointing at Blocks, relative to the base block.

[river oracle]

how effective would it to be to check if an interaction occurred on such a structure though wouldn't that be a fairly large operation to check every time. If i'm understanding this right it'd kind of be like a Linked type structure in which every node only knows about the nodes surrounding it and so on

[sacred mountain]

i know that this isn't the place for specific api support, but the discord is somewhat inactive, so i was wondering if theres a way to create a bukkit advancement object and then when i use Bukkit.advancementIterator() it would be included

not sure if that's possible but lmk

[worldly ingot]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/UnsafeValues.html#loadAdvancement(org.bukkit.NamespacedKey,java.lang.String)

[river oracle]

this is exactly the place for specific API support btw

[worldly ingot]

Although that's in JSON format. There's no pretty API way to do it

[lost matrix]

When the chunk loads then you load all multiblocks into memory ofc. pdc is only accessed on chunk load/unload

[worldly ingot]

Some people did make APIs around it though https://github.com/Roxeez/AdvancementAPI

[sacred mountain]

oh i see

https://github.com/frengor/UltimateAdvancementAPI

this thing then

i was trying to convert a BaseAdvancement class into the bukkit Advancement

but it seems like their entire framework is custom

[river oracle]

oh by specific API I thought you meant like bukkit API

[worldly ingot]

Yeah they're using some reflection insanity in that

No clue why

[sacred mountain]

and only accesses minecraft stuff at a lower level than im willing to look at

i saw some classes and just kinda

brain closed

[worldly ingot]

I'd opt for the one I sent, personally

[sacred mountain]

i'm not great with reflection, i've dabbled a bit in the simple stuff but not really this

[worldly ingot]

The one I sent above at least makes use of API. Unstable API, but it uses API

[river oracle]

ahhh okay. So even when loaded into memory though how would I obtain what multiblock has been has been interacted with etc would I use something like a Map<Location, MultiBlockStructure>? within memory seems like it'd be fairly decent to me

[sacred mountain]

hmm since i've already got quite a few custom advancements already built in and working, would it be worth it to just make a converter for the plugin that is using the iterator?

like just have them as extras

so currently i have an advancement display gui

and it should just display all the advancements in the game, i could just add the custom ones on at the end

[tall dragon]

tell em to click their mouse

[sacred mountain]

💀

install killaura idk

[fading dirge]

why i cant use znpcs on aternos

[sacred mountain]

aternos servers run on outdated potatoes

[quaint mantle]

why does it only flag it if I add the @NotNull in the generic spot

but it doesn't flag the other ones

[river oracle]

because @NotNull on the list side technically means the contents could be null

but the list will never be null

[river oracle]

however conventional wisdom will tell you that @NotNull on the list probably indicates that the contents shouldn't be null

I'm aware

that means the contents shouldn't be null

having the notnull only on the list part means the contents COULD be null, extremely stupid, but whatever

[quaint mantle]

Do I just ignore it then

[eternal oxide]

Those annotations are only advisories.

[river oracle]

^ I would ignore it

[dull goblet]

What would be a good way to add websockets to a spigot plugin?

[lost matrix]

Start a new thread and open a socket on it

[dull goblet]

Any recommended library that works well with it?

[slender elbow]

client or server?

[eternal oxide]

Java

[dull goblet]

Server

I've used vertx before

but not with spigot

[chrome beacon]

I've you're familiar with it then you can just use that in a different thread

[dull goblet]

I haven't done much with threads except for small things, any things i need to watch out for?

[chrome beacon]

Many things in the Spigot API are not thread safe

So you want to jump back to the main thread when doing stuff

and an easy way to do that is using the scheduler

[river oracle]

I'd say most things aren't very few exceptions. ChunkSnapshots is the only things I can think of off the top of my head

[chrome beacon]

Yeah

[river oracle]

Most read operations are semi-safe on another thread

though under specific circumstances they most likely can cause errors

[dull goblet]

That seems difficult, any guide somewhere that talks about going back to the main thread?

[chrome beacon]

?scheduling

[undone axle]

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

[chrome beacon]

Schedule a task to run next tick

That will run on the main thread

[river oracle]

BukkitScheduler#runTask(Runnable)

Bukkit.getScheduler().runTask(() -> System.out.println("I'm on the main thread now mom"));

[dull goblet]

So then i for example send something through the socket every one tick?

[river oracle]

in what world would you need to send something through a Web socket every tick?

sounds extremely heavy

[dull goblet]

its like a plugin where people can race and there is a live leaderboard on a web app for it

[river oracle]

ahhhh

just remember don't do spigot tasks on the asynchronous therad

[quaint mantle]

is there a way to make it so intellij doesn't put the @NotNull here

[river oracle]

you'll get errors most likely

[quaint mantle]

cause whenever I auto implement the methods

it puts it there

[chrome beacon]

is characterInformation marked as not null?

[quaint mantle]

yeah

[chrome beacon]

That would be why

[quaint mantle]

but I want it like

@Override
@NotNull
public void ...

unless that's not the convention

[river oracle]

they probably want the annotation on top of the method like a normal person

[quaint mantle]

honestly idek

cause if I have a list

it would be weird

[chrome beacon]

Different people want it in different places. You can configure it in the settings

[quaint mantle]

@Override
@NotNull
public List<@NotNull String>

compared to

@Override
public @NotNull List<@NotNull String>

[quaint mantle]

I think it's a bug

cause it's like this

instead of that

[river oracle]

I don't think its a bug

[chrome beacon]

^^

[river oracle]

just need to change your format settings

[chrome beacon]

Check your code style settings

[quaint mantle]

I'll just keep it next to the return type

[river oracle]

do you use the annotations on the arrays and list

I hate that which is why I just use the java 5 annotations

[quaint mantle]

wdym

[river oracle]

the @NotNull List<@NotNull Object>

[chrome beacon]

I usually don't do that

[river oracle]

I thought it was like a common inferance that a returned collection of any type shouldn't ever really be null

[chrome beacon]

Yeah I always assume it's NotNull by default

If there for some reason would be a null value I would mark it as such

[south mason]

[lost matrix]

You need to shade spring into your plugin or else the classes wont be on the server when it starts

[south mason]

Sorry, I'm new to programming, could you suggest resources on which to study this topic

[lost matrix]

If you are new to programming then spring is not something you should touch to be honest.
They have a ton of concepts that make no sense if you dont know meta programming.

[lost matrix]

What is your goal with this spring server running on spigot?

[south mason]

I just want to run the site from a plugin

[lost matrix]

    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>

                </executions>
            </plugin>
            ... etc

This is how you setup the shade plugin in your pom.xml

[lost matrix]

Ok but why

[south mason]

I would like to create a plugin for the bank

[river oracle]

don't run the entire website off the plugin, just interact with the website from a plugin

[dull goblet]

I have a websocket server through vertx in my spigot plugin. What port do i use? Can i use a custom port or does it need to go through the minecraft server port?

[river oracle]

this can easily be done with WebSockets or some form of Rest API

[river oracle]

you probably shouldn't use Minecrafts port or your code will error since the port will have already been bound

[south mason]

Okay, thank you all for your help. I'm going to try

[lost matrix]

How would you imagine running two applications through the same port should work?
Imagine if spigot gets some http packets. It would be confused as hell and just throw it away.

[dull goblet]

Yeah i got confused because my client couldn't connect but the ports were right.

I found the problem tho, its CORS

[rotund ravine]

Funny question

@last temple I suppose if you hold a strong reference to the player var and they leave that might be set to null hmm

[river oracle]

or fake players

sus

what's the IP for 👀

that's much less fun than timezones

guh no one is gonna do player based time detection based on their timezone!

[soft tendon]

Hey, quick question - does this take into account that 1.20.2's ClienboundLoginDisconect packet can be both a raw string or a component?
According to a decompiled 1.20.2 client, the client tries to read the received string leniently & deserialize accordingly to what was received (raw string, or component)

[slender elbow]

the reason field in the packet is a Component and is serialized as such

the server can only send a component

[soft tendon]

For the normal disconnect packet yeah, but isn't the login disconnect one a special case for backwards compat?

[slender elbow]

the 1.20.2 login disconnect packet is also just a component

https://mappings.cephx.dev/1.20.2/net/minecraft/network/protocol/login/ClientboundLoginDisconnectPacket.html

[soft tendon]

Sure, that's what it is internally, but the reason is deserialized differently with the login disconnect packet vs the normal disconnect packet - atleast affording to a decompiled jar with e.g. yarn mappings

Not sure if allowed here, ill delete if it isnt - but see here how the serialization happens

[alpine swan]

does getNearbyEntities (world class) only get entities where the center of their hitbox is within the getnearbyentities hitbox or can any part of the hitbox of the entity be within the getNearbyEntities hitbox
also, is entity.getnerabyentities more optimised than world.getnearbyentities?

[lost matrix]

iirc it creates a BoundingBox and checks for any overlapping box to its own

[alpine swan]

alr, do you know if entity.getnearbyentities is more optimised than world.getnearbyentities?

[lost matrix]

The former delegates to the same method as the latter

[river oracle]

smile beat me too it 😦

[lost matrix]

[alpine swan]

alr thank u

[slender elbow]

i mean, i can't tell you why the client does that, but the server can only send a component and that's been the case for the better part of the last decade

[pine forge]

Does anyone know how this protocolllib code would work in 1.19.3 and higher where you have to use the getDataValueCollectionModifier. Not sure what would be the equivalent to this setEntity of the datawatcher

WrappedDataWatcher watcher = new WrappedDataWatcher();
watcher.setEntity(player);
watcher.setObject(DW_ARROW_INDEX, WrappedDataWatcher.Registry.get(Integer.class), arrowCount);

packet.getWatchableCollectionModifier().write(0, watcher.getWatchableObjects());

[lost matrix]

Snippet from my Hologram tutorial

[pine forge]

Okay thanks ill try that out

are the indexes equivalent to the ones specified in wiki.vg?

Number 12 would be the correct one if i want to control the number of arrows in an entity right?

[dull goblet]

I am currently hosting a websocket server through vertx in my spigot plugin. When i connect it works, but when i try to send a message from client to server, I get INVALID_STATE_ERR in vertx-eventbus. Now normally when this happens, it's because an error happened on the server side. But for some reason vertx server side isn't throwing any errors in the spigot console. How can I make it so that happens, or is vertx just not throwing any errors?

[alpine swan]

you cant add chatcolors?

or do you need to put an empty string first if you want to add multiple at the start of a string

[dry hazel]

correct

[sterile token]

Just asking, why using your own program for sending data thru servers? You can barelly use Redis, you skip all this problems, you wont get something as fast as redis

[dry hazel]

redis requires you to have an instance of it, a (web)socket goes point to point

[echo basalt]

A websocket needs to be secured but it's slightly faster

[lost matrix]

websockets can get really messy really quick with multiple conversation participants

[shadow night]

websockets are a mess by themselves

[quaint mantle]

Websockets just transfer json?

[lost matrix]

You can also just tranfer binary data *if you have the right protocol to deserialize it on the other side

[shadow night]

binary data is kinda ass

[dry hazel]

protobuf is alright

[echo basalt]

A <-> B is whatever

[eternal oxide]

binary data is great when you have to pay for the amount of data transfered

[echo basalt]

But messaging systems are purpose built for a reason

[quaint mantle]

Everyone(mostly) have unlimited internet access plan

[eternal oxide]

many businesses dont

in fact many people don;t

[lost matrix]

Lets use the foreign memory api to transfer data directly through memory

[alpine swan]

when would this have not been initialised? how else can i cancel a task inside a task or achieve the same thing

[eternal oxide]

Business contracts pay by quantity of data in most cases

[lost matrix]

You cant reference this variable from the inner scope in a call stack like that.

[twin venture]

How i can get a Chest block from a location instance?

[alpine swan]

what else can I do?

[lost matrix]

Let me write an example

[alpine swan]

World.getBlockAt(Location)

[twin venture]

so for example :
-GameStartEvent -> get save location for the specfic Chest and just fill it when game start

[lost matrix]

    new BukkitRunnable() {
      @Override
      public void run() {
        if(player == null || !player.isValid()) {
          this.cancel();
        }
      }
    }.runTaskTimer(plugin, 0, 10);

[alpine swan]

is there any difference between using a bukkitrunnable and a runnable?

[lost matrix]

    Location location = ...;
    Block block = location.getBlock();

[lost matrix]

Yes. The BukkitRunnable has methods like cancel()
Runnable only has a run method and nothing else.

[alpine swan]

just wondering, why not?

[lost matrix]

    Location location = ...;
    Block block = location.getBlock();
    Chest chest = (Chest) block.getState();
    Inventory inventory = chest.getInventory();
    inventory.addItem(...);
    chest.update(true);

[lost matrix]

Runnable is a plain old java class. It is very commonly used outside of Spigot to simply represent an action that can be ran.

[sterile token]

I just recommended Redis because managing multiple conversations at the same time with Sockets is a mess, even when need performance

[lost matrix]

Runnable is simply just this

[glad prawn]

lol just replace your () -> to task ->

[alpine swan]

i should have thought of that

either way, the error message that it might have not been initialised yet made no sense

[lost matrix]

I really dont like this approach because you can get caught up in confusing scopes like that

[alpine swan]

nvm that does not work

[lost matrix]

It made perfect sense to me. If the lambda would execute instantly, then your variable wouldnt be initialized

[glad prawn]

choose other name your variable name is task

[lost matrix]

Remove the variable declaration from the start

[alpine swan]

oops

[alpine swan]

in what case would it execute instantly though?

i guess it isnt gonna go though the entire bukkit source to figure out if its gonna execute instantly

[alpine swan]

didnt work either

[lost matrix]

Because this is not deterministically analyzable. Its a specification of spigot.

[lost matrix]

Show your code

[glad prawn]

ig u doesnt know how to use lambda

[lost matrix]

I really dont like the excessive use of lambdas. Creating a concrete implementation is the safest way for newer devs to get a hang of it.

[glad prawn]

yes but i talk to him

[shadow night]

Lambdas are weird

[alpine swan]

• part of a serverside autoclicker

i mean yea i havnt tried to do something like this with a lambda before so idk what id run into

[lost matrix]

Remove the variable declaration

[alpine swan]

i need to save the bukkittask somewhere else though to be able to stop it from a different part of my code

it gets dumped into a hashmap

[lost matrix]

That sounds like an absolute mess.
In that case you cant use this lambda.

Im giving you a task now: Create a new class, name it appropriately after your task, and let it extend BukkitRunnable.

[alpine swan]

any reason not to just use an anonymous bukkitrunnable?

it works fine

[chrome beacon]

Deprecated (in the scheduler) also not very clean

[alpine swan]

actually this is a mess im making my own class

[lost matrix]

Yes, plenty of reasons. Making you pass variables through the constructor shows you the scope in which you enslave them.
You will see that having a player reference in there is a bad idea.

[zealous osprey]

Eyyy, even more bit stuff, here I go again:)
I have a mask, so I can get some data back from a long:
X_ONE_MASK = 0xFF00000000000000L
And I have a long of data: 0000110100001011000010010000000000000111000000000000010100000011
I want too get the first 8 bits of the data long, the ones that overlap with the mask. No probleme, a simple & Operator. But now I have this long as a return value:
0000110100000000000000000000000000000000000000000000000000000000 But I want that as a byte? So how can I move the bits too the right? Ik I can use >> but how would I get the amount of shift form the mask?
In the worst case, I'll just create hardcoded values.

[chrome beacon]

Shift and cast?

or am i missing smth

[lost matrix]

You need to predefine the size of your masks. This also determines the amount of shiftes you need.
So hardcoding it is

[zealous osprey]

kk

[alpine swan]

what is wrong with the player reference?

[lost matrix]

You shouldnt keep references to game objects like entities, worlds, chunks and players because you can easily
create memory leaks if you are not careful. Its better practice to use an indirect reference like their UUID and
request them from Bukkit. This has almost no performance impact.

[alpine swan]

how would a memory leak be caused if its constantly checking if the player is valid and killing itself if it isnt? is that not enough of a check?

i understand your point but i dont see why its valid in my specific use case

i might just do it to be safe tho

[zealous osprey]

You could also do the following:

private static byte getFirstOne(final long bits) {
  if (bits == 0) return 0;
  return (byte) ((Math.log(Long.lowestOneBit(bits)) / Math.log(2)));
}

Returns the first occurence of a "1" in the long, so you can just shift by that amount

[lost matrix]

Its simply a good practice which i would enforce for consistency. Imagine having methods in your other classes that take a UUID
and then you have other parts which take a Player. Its just inconsistent converting them around constantly.
In this specific case it wouldnt cause a memory leak.

[lost matrix]

    public static byte getFirstByte(long value) {
        return (byte) ((value >> 56) & 0xFF);
    }

After that you simply need to shift by 8 less every step.

*This gives you the left most byte in this long

[zealous osprey]

In my case I can't really do that, I'm mixing sizes. So my long is split into 2x8 Bits, 4x4 Bits and 2x16 Bits

[lost matrix]

Hm. So the hard part is probably the 4x4 Bits...

The rest are done like the method above

[storm crystal]

should I make separate utility handling class for PDC tags?

[lost matrix]

If you feel like it makes your code simpler and reduces repetitive tasks for you, then sure

[storm crystal]

ill be using PDC tags for pretty much all custom items, enemies and such

so I thought about making a method for both entities and items

[lost matrix]

Ok so lets start slowly extracting your data from left to right. Im just gonna put everything into ints for now.

[storm crystal]

like set, read etc.

[zealous osprey]

Don't worry about it, I'll just hard code it, since the masks are hard coded aswell

[lost matrix]

int firstSegment = (int) ((value >> 56) & 0xFF);
int secondSegment = (int) ((value >> 48) & 0xFF);

Ok so those are the first 2x8 bits

int fifthSegment = (int) ((value >> 32) & 0xFFFF);
int sixthSegment = (int) (value & 0xFFFF);

Those are the right most bits.
The middle can probably be extracted with a loop. Let me test something real quick

[lost matrix]

int[] segments = new int[4];
for (int i = 0; i < 4; i++) {
  segments[i] = (int) ((value >> (44 - 4 * i)) & 0x0F);
}

Ok i think this should do it. So it skips the first 16 bit (bc of the 2x8 before them).
Then it shifts the long 4 times with each shift being 4 greater than the previous.
This should result in the 4x4 values after the first 16 bit.

I mean... you could also just hard code the values and not use a loop.

Thats probably easier

Just make sure to use a 0x0F mask for your 4 bits

[zealous osprey]

ye

[wet breach]

you could just split the long first into the appropriate sizes

[zealous osprey]

I love how you were a "man on a mission".

[dull goblet]

A while ago i found a spigot resource where you made 2 maven profiles one build and one dev, and in the dev you put outputpath as your plugin folder, but i don't seem to find that resource back

[chrome beacon]

https://blog.jeff-media.com/how-to-make-maven-automatically-put-your-plugins-jar-into-your-test-servers-plugins-folder/

[dull goblet]

yes that one thanks

[weak meteor]

So, im working on cooldown and stuff, and i wanna know if using long as ticks is the best option:

and i know 20 ticks is a second

so i can make if (Long % 20) {
seconds = seconds-1
} or smth like that

[lost matrix]

I would suggest using a Long but as a unix timestamp. (ms)

[rotund ravine]

Keeping track via ticks is a bad idea

[chrome beacon]

You can use a tick timestamp instead if you want the cooldown to match the game time

[weak meteor]

how should i do it?

cause it was smth like this:

or that i was thinking

[sterile breach]

Hello, I have a question
When I Register a command using plugin.yml. spigot register the command in the global command map is that correcte ? So the command will be registered like if we register it without plugin.yml?

[dull goblet]

How to structure a controller that is bidirectional? For example, i have a controller with function broadcast, which broadcast to my website, but the website can also broadcast to my spigot plugin. Do I make a seperate controller for that?

[weak meteor]

if you doesnt register the command in plugin.yml it will not work

dont register*

[sterile breach]

We can using the commandMap directly

[onyx fjord]

yes you can forcefully register with reflection

make the map accessible and add your command

[sterile breach]

Spigot just add the command from plugin.yml in command map or its another system ?

[onyx fjord]

idk, what you wanna do?

[sterile breach]

No I am just asking about handling of commands

[young knoll]

Yes spigot adds them to the command map

[sterile breach]

So a command added with plugin.yml will work just as well as a command added directly in commandmap?

Or will there be a few differences?

[young knoll]

yes

[onyx fjord]

#1170412914428084375 thanks jetbrains

[sterile breach]

What are they?

[onyx fjord]

it will work just as well @sterile breach

[sterile breach]

Ups srry

I've noticed that commands are added directly to the command map. If I make them a permission set for example. And low the permissions will not apply and at the time of executing the command spigot will not check if the user has permission and it will trigger the handler directly. Is this correct?

[timid hedge]

I know it isnt the right place but i dont know where else to get help

But does anyone know why i cant use keyBindForward.isPressed? (mcp 1.8.8)
if(mc.gameSettings.keyBindForward.isPressed){

[ocean hollow]

Is it possible to play sound from a resource pack in a plugin?

[young knoll]

Yes

You can play a sound by name

[ocean hollow]

that is, you can launch a custom sound without replacing the vanilla ones?

[young knoll]

Yes

[timid hedge]

.?

[young knoll]

No idea

[timid hedge]

Okay fair

[pseudo hazel]

mcp is ancient

[chrome beacon]

and so is 1.8.8

also you can't distribute what you make with MCP

[weak meteor]

String#isEmpty refers to if its null?

cause, im making a cmd where 'arg' is the first element in the array of strings on the command

[pseudo hazel]

no

[eternal oxide]

if String is null it has no #isEmpty

[pseudo hazel]

== null refers to if its null

[weak meteor]

okay

thanks

still the same error

where strings is the array of subcommands in onCommand method

what should i do?

[eternal oxide]

does element 0 exist?

[weak meteor]

well, no

[eternal oxide]

then you can;t read it can you

[weak meteor]

i cant

but idk how to manage that

[eternal oxide]

of course you can;t, it doesn;t exist

[weak meteor]

thought with == null its okay

[eternal oxide]

arg = string{0} is impossible

[weak meteor]

it is

but then how can i identify if it has a arg or not

[eternal oxide]

as 0 does not exist, it's not null, it does not exist at all

length

[weak meteor]

oh

so

strings.lenght > 0?

[eternal oxide]

if args.length >0

yes

[weak meteor]

k

thanks

[eternal oxide]

if it's 1 you have an element 0

[weak meteor]

im using Duration#toString but PT is like weird

[river oracle]

you could use Duration#toSeconds()

if you want to format, more perfectly you'll need to make something yourself

[eternal oxide]

Yeah don;t use toString https://www.baeldung.com/java-period-duration

[weak meteor]

k thanks

[weak meteor]

i tried

didnt work

[ornate patio]

Hello, I have a question. When I import spigot 1.20.1, it doesn't find the JavaPlugin class ?

[hazy parrot]

how do you "import" it ?

[ornate patio]

import org.bukkit.plugin.java.JavaPlugin; but it can't find the plugin folder

[hazy parrot]

and how do you include api in your project...

[ornate patio]

https://imgur.com/a/q3IIG2d

Maybe because it doesn't display the source line, but I don't see how to fix it.

[smoky anchor]

Do not depend on this jar with IJ, use maven to manage the dependency instead

(or the other one, forgot name)

[ornate patio]

Do you know of any documentation for adding it?

[remote swallow]

?bootstrap

[undone axle]

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

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

[ornate patio]

it works the same way for version 1.20.1 ?

[remote swallow]

yep

[ornate patio]

okay thanks, I'll take a look at it

[storm crystal]

how can I make a zombie wear custom player head?

[young knoll]

get their equipment and use setHelmet

[storm crystal]

oh yeah I get that part but idk how to set up custom player head

[young knoll]

From a player name or what

[alpine swan]

is there any way to detect when a player opens their own inventory

using packets is fine, i just want to know if there is any possible way of detecing it, ive found conflicting stuff online

[worldly ingot]

There is not, no. No packet is sent to the server for that because it doesn't really need to be

Server doesn't particularly care whether or not that screen is open, just if a slot in the player's inventory changes, for which there is a packet :p

[hazy parrot]

What would be most convenient way to pass logged user from spring to react frontend. I don't like the idea of having separate endpoint (/user/me for example). Is passing trough thymeleaf actually alright ?

[olive vault]

I've been using nms for a while now but all of the sudden it just breaks on me, i've tried restarting, reinstalling buildtools and more but nothing? anyone help

[alpine swan]

oh thanks

i think there was conflicting information because it was possible in older versions

[worldly ingot]

I don't recall that being the case

[chrome beacon]

You're calling methods that don't exist in the api on what appears to be api objects

[olive vault]

oh

[chrome beacon]

That code has nothing to do with nms as far as I can tell

[storm crystal]

I asked here earlier if its possible to make several plugins use same custom config but it's not really the best practice, what could I do to make them use same source of information such as custom enemy, weapons etc. data that was initially stored in plugin's custom configs?

since now I basically stuff everything into one plugin but that doesnt sound optimal at all

[river oracle]

make an API

[storm crystal]

do you have any resources on that?

[hollow lagoon]

Hello, I have a problem with the placement of my structures, I can get them from the StructureManagaer but not do the .place, I have no console error and the code which is after is executed correctly, could someone help me ?

System.out.println(Main.getInstance().getServer().getStructureManager().getStructure(new NamespacedKey(Main.getInstance(), "tir-a-arc-1")).getSize());
            Main.getInstance().getServer().getStructureManager().getStructure(new NamespacedKey(Main.getInstance(), "tir-a-arc-1")).place(player.getLocation(), false, StructureRotation.NONE, Mirror.NONE, 0, 0f, new Random());

and I am also sure that the structure exists and that the rental does too

[smoky oak]

not sure on this one but i assume Main is your JavaPlugin instance. The structure would need to be registered to PluginName/StructName if i remember this correctly

[hollow lagoon]

yes the Main is where I extend my JavaPlugin

and my structure is indeed registered because otherwise I would not be able to get the size of it

[shadow night]

(don't ever name your plugins main class Main, might cause issues from what I know)

[hollow lagoon]

In this case it is useful and does not pose any problems

[shadow night]

It might not cause any issues right now, but it's bad practice to name your main class Main in a plugin. Just saying. It's up to you what to name your main class ¯_(ツ)_/¯

[smoky oak]

might be an idea to store the structure and check with a debugger what's stored in it

do you have ur debugger setup yet?

[hollow lagoon]

no

[smoky oak]

https://www.spigotmc.org/wiki/intellij-debug-your-plugin/

should be pretty similar with other IDEs

[hollow lagoon]

i never try this

But in fact what I did worked yesterday that's why I don't understand

[shadow night]

Another thing, might not fix your issue, but you are making a lot of Main.getInstance() calls. Instead, you should call Main.getInstance() once and save it to a variable and then use that variable everywhere.

[hollow lagoon]

yes but this is for testing and it doesn't really pose a problem to call it 3/4 times

[shadow night]

Makes sense, but saving it to a variable saves some time.

[desert tinsel]

Is there a difference by using JavaPlugin with dependency injection by constructors, / using it with static methods like that from above: Main.getInstance();?

[candid galleon]

I find that using the singleton pattern (static) is more convenient

technically there's a difference

[hollow lagoon]

System.out.println(plugin.getServer().getStructureManager().getStructure(new NamespacedKey(plugin, "tir-a-arc-1")).getPalettes());
            plugin.getServer().getStructureManager().getStructure(new NamespacedKey(plugin, "tir-a-arc-1")).place(player.getLocation(), false, StructureRotation.NONE, Mirror.NONE, 0, 0f, new Random());

[candid galleon]

but for spigot plugins i wouldn't worry abou tit

[shadow night]

I prefer dependency injecting my instances just because yes

[candid galleon]

I try to stick to DI

but sometimes you get stuck in a corner

[hollow lagoon]

i dont hacve constructor on this, it's command and i juste have onCommand

[shadow night]

you can add a constructor with no issues

[candid galleon]

getInstance can't be that performance impactive

[ivory sleet]

yes, from a design point of view

[shadow night]

If you do it only once per a class, then it's basically nothing

[hollow lagoon]

But that's not the question, I just came for the place() Structure at the base, can you help me with that?

[ivory sleet]

I mean there are some cases where its like, let's use static instead of instances, for instance why AtomicFieldUpdater exists

[desert tinsel]

sometimes I just use for example in a command / listener class something like this:

public CommandClass(Main plugin){
  this.plugin = plugin;
  plugin.getCommand("command").setExecutor(this);
}``` and then just call ```java
new CommandClass(this);``` in onEnable()

[ivory sleet]

u should move the setExecutor part to below

[desert tinsel]

but Bukkit.getPlugin(); or something like this should work too

[shadow night]

Or you can have another class with the plugin instance injected into it to call the new class instance thingy

[hollow lagoon]

^

[candid galleon]

What do you mean by but not do the .place, ?

does the method not show up?

[ivory sleet]

Anyway, the point of passing the instance instead is that you don't tightly couple your code to rely on specific instances. Since a singleton binds a class to a specific instance. Avoiding that may be resourceful if you care about not making your code spaghetti long term, now that doesn't mean singleton is inherently bad since it definitely has its use-cases. We get more re-usability, flexibility and testability when we avoiding design patterns that tightly couple our code, on the other hand we may have to compromise the simplicity of the code architecture or other properties at times. @desert tinsel

[hollow lagoon]

I hear that the function is executed but nothing has been done in the world

[desert tinsel]

at the moment I pass the instance, but I used to work with static values too

[ivory sleet]

yes as said, both works

but just because a design works doesn't really imply its the best one to use in that said context

sometimes not using the most suitable design is fine ofc

[echo basalt]

mr lube you never answered me

[ivory sleet]

sorry, what did I miss? ,:)

[echo basalt]

.

[desert tinsel]

but sometimes I just need to have a util method that needs a JavaPlugin instance once, and I need to pass the dependency through 2-3 methods

[upper hazel]

This is probably going to be a complicated topic, but I'll still ask how I can make a chunk generator that will ADD to the vanilla generator, and NOT CHANGE it.

use minecraft code?

[ivory sleet]

A common mistake is to use short names for variables, such as "p" for player, or "i" for index. This is a bad practice, as it makes your code harder to read and understand. Instead, use descriptive names, such as "player" or "index".
Yeah well that's partly true, the industry convention is to name variables proportionally to the scope they're declared within. For instance a for loop that doesn't do much and isn't exposed to much doesn't need its increment variable named "index", just "i" is fine there.

Re-use variables when possible:, Avoid repeating collections calls:, Perform the most performant checks first, Don't expose mutable collections, the principles etc are all good, I suppose you could just try to use wrapped types when u want primitives with nullability else yeah good stuff, some but not all is basically effective java items 😅

[echo basalt]

i for index is a weird edge case

[shadow night]

[echo basalt]

Hi guys, could you guide me on how to improve messages in my plugin to minimize redundancy? https://github.com/SzinDzeks/ChunkyPlots/

[ivory sleet]

thats a pretty bad utility method

[desert tinsel]

wdym

[ivory sleet]

well actually, do u mind sending the utility method?

[echo basalt]

Also added a block for premature optimization

ow that command manager

[desert tinsel]

public static void openInventory(Player p, BossEvents plugin) {
        Inventory voteInventory = Bukkit.createInventory(null, 27, "Buy an item");
        voteInventory.setMaxStackSize(3);
        for (Item item : plugin.getItemsManager().getItems()) {
            ItemStack is = new ItemStack(item.getMaterial());
            ItemMeta meta = is.getItemMeta();
            meta.setDisplayName(item.getName());
            meta.setLore(Arrays.asList("Price: " + item.getCost()));
            is.setItemMeta(meta);
            voteInventory.setItem(item.getSlot(), is);
        }
        p.openInventory(voteInventory);
    }```

[ivory sleet]

so well, I wouldnt call that a utility method

its more a clumsy static helper method

[desert tinsel]

idk these names

[ivory sleet]

well, a utility method is pure and stateless, meaning that it wont ever return void

[echo basalt]

Also added guard clauses at the top

[ivory sleet]

a static helper method just does a bunch of stuff, in principle

[echo basalt]

got a solid 10 characters to spare

should be good now

Files (yml) have to be created/saved as utf-8 too

[pure stag]

For tests I changed displayName in code

[eternal oxide]

Then you can't be compiling in utf-8, or your IDE is not set to utf-8

[upper hazel]

I'm trying to learn how to create custom chunk generators but I don't understand the point of these methods - https://paste.md-5.net/aqitunevul.java - for what they need??

[smoky oak]

aint utf8 default for both IDEs and file IO?

[eternal oxide]

no

not always

[lost matrix]

setBlock is not a method of ChunkGenerator (anymore?)

getDefaultWorldGenerator can be overridden to let your generator be used by the default world

[upper hazel]

in tutorial i was see setBlock in Impl ChunkGeneration

[eternal oxide]

probably old

[upper hazel]

damn I didn't find more recent tutorials

Did I understand correctly that the successor of chunkGeneration is the chunk itself in Minecraft and all its methods are overridden to fill the chunk with their own systems?

if so can I override the vanilla generator and change it a little?

[sullen marlin]

Sorry don't understand the first part

But yes you can override vanilla with the should methods

[icy beacon]

Exception ex ☝️

[ivory sleet]

e is fine

[icy beacon]

Idk looks a bit ugly

I have a habit of naming Exceptions at least ex because I used to do stuff like Player p back in the day, and so exceptions would clash with entities lmao

[shadow night]

lol

[rotund ravine]

Laughs in kotlin

[icy beacon]

I do use kotlin now

Primarily

The habit has stuck though

Wasn't spigotcraft pfp yellow

[rotund ravine]

Never

[icy beacon]

Shit. Solo Mandela effect

[shadow night]

not solo

duo

[icy beacon]

yOU ALSO THINK IT WAS YELLOW??

We gotta find some old screenshots of this server

Like year-old ones

It was gray. Welp

[eternal oxide]

Ouchie

[echo basalt]

bro sending finger pics

[quaint mantle]

Its6am

[smoky oak]

its 12 am

[rotund ravine]

Gray

Some post from alex ages aho

Ago

[lost matrix]

Yeah that looks about right...

[echo basalt]

wait this is not general

explains why 7smile is here

[lost matrix]

[smoky oak]

this is general what are you on about

[inner mulch]

Is there an event for when a player middle clicks a block in survival?

[rotund ravine]

What does that even do

[inner mulch]

Nothing, but it works in creative

[shadow night]

in survival it'll take the same block from your inventory into your main hand if you have it, obvioulsy

[grim hound]

is there somewhere a general method where the server sends the packets to all the channel handlers?

[rotund ravine]

What

[ivory sleet]

i mean u can inject each player when they join, think thats what most devs do

but to answer ur question, prob not (speculation only)

[grim hound]

that's what I also do

what if there's a like a player list update packet it's sent to everyone equally

[ivory sleet]

hmm, iirc there are some helper methods to dispatch a packet to a certain chunk or level etc, and then that level/chunk will just delegate those packets to the players contained within them

something like that at least

[upper hazel]

is the vanilla chunk generator registered in the same way as in the plugin through the abstract class chunkgeneration?

[rotund ravine]

Probably not

[upper hazel]

As I understand it, you need to convert the Minecraft code to bukkit api methods?

[echo basalt]

You just described craftbukkit

[upper hazel]

ah?

oh yea

craftBukkit load

this all

[ember estuary]

What are the most common mistakes when making a plugin, in regards to server performance?

(For example (atleast I think that‘s bad): creating a scheduler for each player instead of having a single scheduler in which i loop over all players)

[rotund ravine]

There’s so many

[ember estuary]

My MSPT is at ~48 and i wanna get it down a bit, so I‘d like to check my plugin for such mistakes.

[ember estuary]

Hmm, but like most common or highest impact?

Is using PlayerMoveEvent a lot bad?

[hybrid spoke]

dont do unnecessary shit, dont do shit twice, dont do expensive shit in high frequency events

[ember estuary]

Say i want to detect when a player is in a certain area. Should i have a 1 second repeating scheduler that checks all players, or should I just check it in the MoveEvent

[hybrid spoke]

not having common sense is the biggest mistake

[deft thistle]

obv the movevent as you won't toggle it for afk players.

(i believe)

[ember estuary]

Hmm yea that makes sense

But on the other hand, the moveevent is triggered like 20 times per second per moving player, whereas the loop will only run once per second

[rotund ravine]

Usually you’d go with the scheduler

PlayerMoveEvent is very expensive due to it being called an absurd amount

[hybrid spoke]

the moveevent is triggered even more often

multiple times per tick

[rotund ravine]

Generally just avoid moveevent

If you really really need it make sure it’s cheap logic

[young knoll]

If you really want to know what’s going on

Make a spark report

[grim hound]

PlayerMoveEvent, the performance graveyard

[grim hound]

do they need to be moving?

[eternal oxide]

early exit unless to and from blocks are different

[rotund ravine]

Hm?

[hybrid spoke]

to avoid evaluating jumping, movings inside the same block or crosshair movement

[rotund ravine]

Oh yeah i get what he meant now

[grim hound]

which one should I go for?

the second one executes the tasks always a tick late but there is no need for synchronization at task addition

both work

(probably)

[rotund ravine]

ahaha

[valid burrow]

keep both and try around when youre done with everything switch to the other one and test the difference

[grim hound]

I mean the second one is faster but introduces a 1 tick must-delay

but the first one is how you should properly handle multi-threading

[valid burrow]

multi threading? minecraft is entirely single threaded though isn’t it

[young knoll]

no?

It hasn't been for a long time

Netty has threads, chat is another thread, worker threads are used for worldgen

[valid burrow]

damn

when did tht change

what did i miss

[rotund ravine]

Ages ago

[valid burrow]

damn

[grim hound]

when they first introduced servers

[slender elbow]

the tick loop is single threaded, that's about it

[grim hound]

so like

2011

or 12

[slender elbow]

i mean, chat is another thread on (craft)bukkit (+ forks), it's sync on vanilla lol

[valid burrow]

i believe yall over reddit and google but all sources i find say its still single threaded xd

[young knoll]

Wait the chat thread is a bukkit thing?

[grim hound]

just look at the source code

[young knoll]

huh

[slender elbow]

again, the tick loop is single threaded

but the entirety of minecraft does not run on a single thread

that would be horrible

[grim hound]

single-threaded is used here for the meaning that the main server logic is synced

[valid burrow]

yh but that is about 99% of the usage isnt it

[young knoll]

I think the main benefit that could be introduced is threaded entity ticking

[grim hound]

unlike Folia for example

[young knoll]

Look out for my new fork

[grim hound]

no

[young knoll]

DeluxeAsyncEntityTickingSpigot™️

[wet breach]

most of the information you are finding on google is outdated information that no one has bothered to update

[grim hound]

the entire netty communication is async

[valid burrow]

look at the screenshots ut holds dates too

2023, 2021 etc

[wet breach]

idk what those dates mean

[grim hound]

.

[grim hound]

/\

[grim hound]

.

[valid burrow]

im not saying i disagree

its just that i cant find anything about it and i wanna read about it xd

[young knoll]

Not really much to read

Communication is handled by the netty threads

Worldgen does some wacky passing between worker threads

And chat is just chat

[quaint mantle]

Just imagine what would be if netty channels are synced

[shadow night]

sounds crap

[rotund ravine]

what is this code lol https://puu.sh/JTSHN/f0cb9192c2.png

[river oracle]

New spigot fork dropping soon SyncChatSpigot

[wet breach]

not sure if you will find some third party that has covered the changes, but you can see the changes in the source code though 🙂

[rotund ravine]

How would it accept new packets?

[river oracle]

Sync it

[shadow night]

you don't need to

[rotund ravine]

Poor chat

Lol

This plugin right https://www.spigotmc.org/resources/nest.113419/

It's such shit ahaha

[river oracle]

Just freeze the sever until we get the next chat packet

[young knoll]

Might be fun to try and make entity AI async tbh

[rotund ravine]

Yatopia

anyone

[grim hound]

tis

[young knoll]

Did they do that?

[grim hound]

from tis'?

[young knoll]

I never used it

[rotund ravine]

nono

[rotund ravine]

The Nest thing is just this https://puu.sh/JTSIe/11fb2b333a.png

[grim hound]

wtf is this

[rotund ravine]

Nothing

[river oracle]

Very optimized 10/10

[young knoll]

Placebo effect

[grim hound]

what does this even do?

[young knoll]

Very stronk

[rotund ravine]

Nothing other than printing messages

[young knoll]

Nah man Nest uses a custom chunk loader called Nester, which improves chunk loading by determining where players spend the most time.

[rotund ravine]

Suure

[river oracle]

I hate all these performance plugins I'm about to make AsyncMemoryLeakPremium

[rotund ravine]

Kofi builds confidnece https://puu.sh/JTSIA/c923a22848.png

[river oracle]

Make memory leaks on a whim

You can leak a certain amount of memory on a timer

Omg I'm going to be rich

[grim hound]

I once made a ServerSabotager plugin

[young knoll]

New server shutdown timer

[river oracle]

Is it async?

[young knoll]

Slowly leaks memory until OOM

Yes we will leak the memory async

[river oracle]

Thank god

[grim hound]

Behold

my newest creation

ServerOptimizerPremium 1.0 BETA

[wet breach]

You could always do the opposite and randomly remove a pointer lol

[remote swallow]

You dont run it

[river oracle]

Genius

[shadow night]

oh my gosh

[young knoll]

How many threads is that

Someone do the math

[shadow night]

like a fuck ton

[remote swallow]

Ur a helper help us by doing the math

[grim hound]

you mean

[grim hound]

this

?

[wet breach]

Threads are largely dependent on current memory in system

[young knoll]

Okay well, how many does it try to make

[rotund ravine]

Coroutines go stonks

[wet breach]

Will probably try to make an infinite amount lol. But at 64gb of memory and the system using 2gb of it you could have like 200k threads if my math is correct

[grim hound]

Yes, it approaches infinity

[pine forge]

Hey, im trying to hide a player's equipment with protocolllib and im getting this exception:
This is my code:

PacketContainer packetContainer = new PacketContainer(PacketType.Play.Server.ENTITY_EQUIPMENT);
packetContainer.getIntegers().write(0, player.getEntityId());
packetContainer.getItemSlots().write(0, slot); <- error

[worldly ingot]

There’s api for this in modern versions

Player#sendEquipmentChange()

[pine forge]

ah okay thanks

[lost matrix]

Doesnt this have like a List<Pair<Slot, Item>> field now?

[worldly ingot]

Also, yeah, for future reference, ProtocolLib operates off of fields in the packet class, not the actual protocol data

[pine forge]

okay what would be the correct field for this then?

[worldly ingot]

Not sure off memory. Probably getItemSlotPairs() or something

[pine forge]

getSlotStackPairLists?

[worldly ingot]

That's the one

You are best to use API though because it does all this for you and faster

[pine forge]

Yea, ill use that one

Thanks for the help

[lost matrix]

Which translates to something like

    PacketContainer container = new PacketContainer(PacketType.Play.Server.ENTITY_EQUIPMENT);
    container.getIntegers().write(0, someId);
    
    List<Pair<EnumItemSlot, ItemStack>> slotStackPairs = new ArrayList<>();
    slotStackPairs.add(new Pair<>(EnumItemSlot.MAINHAND, new ItemStack(Material.DIAMOND_SWORD)));
    
    container.getSlotStackPairLists().write(0, slotStackPairs);

[pine forge]

yea

ill use the api though

[rough drift]

Can you stop chunks from being sent to a player without using ProtocolLib/NMS

[weak meteor]

so, im trying to do a restAPI but idk if thats the right software to use

[upper hazel]

By the way, why is interacting with the chunkLoadEvent chunk more expensive than creating your own chunk generator?

[rotund ravine]

Think about it

[grim hound]

You can also use PacketEvents. Otherwise no

[wet breach]

yes

you would have to stop the server from reading the chunk in the region file

if the server can't read that information or its incomplete, it doesn't get sent

[rough drift]

can I also just cancel ChunkLoadEvent

[wet breach]

sure

[rough drift]

ohk

[wet breach]

just not sure what you were wanting was all 😛

I was under the impression without using the api, what other ways could you stop a chunk from being sent lol

[slender elbow]

i mean you can still make the player load the chunk on the server and get it ticking normally without sending the chunk info to the client, but that does require nms or {packets library of choice}

which falls outside of the presented constraints

[rough drift]

Thanks ya'll

[rotund ravine]

Ur welcome

[twin venture]

Hi i have a question about something iam working on so i have been working on a Default kit for Each user and it will be saved in the mysql database .

so i started by making a PlayerKit class it hold :

• PlayerData class
• String kit name
• ItemStack[] contents
• ItemStack[] armors
  ..
  what would be the best way to serlize the itemstacks and desrlize?

playerData class hold 2 methods :

• void setPlayerKit(PlayerKit playerKit);
  and a PlayerKit playerKit();

with other methods and stats ofc

[lost matrix]

Serialize them to a single String and store them as Varchar

[twin venture]

what if a user changed kit ? how would it remove only that kit items and add the new one?

[chrome beacon]

or as a blob

[twin venture]

i do have a tag on kit items its called : Kit

[lost matrix]

You just overwrite the entry

[twin venture]

can you give an example?

[lost matrix]

Are kits unique to players or can multiple players have the same kit?

[twin venture]

the latter one

[lost matrix]

Where are kits loaded from?

[twin venture]

each kit have its own .yml file

[lost matrix]

In that case, you should not store all items in your DB but only the name of your kit

[glad prawn]

ay Key

[lost matrix]

Why are KitItems addressable via an UUID?

[twin venture]

each item have its own uuid

[twin venture]

json sorry*

[lost matrix]

Ok but why?

[twin venture]

so i can just do that

or other stuff

but its not important i can remove it anywhy

[rotund ravine]

UUID seems overkill

Unless ur doing some duplicate protection

[glad prawn]

yeah name is enough

[pine forge]

System.out.println(event.getAction() + " " + event.getModifiedType());
System.out.println((event.getAction() == EntityPotionEffectEvent.Action.ADDED) + " " + (event.getModifiedType() == PotionEffectType.POISON));

Why doess this comparison of potioneffecttypes not work

[rotund ravine]

?jd-s

[undone axle]

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

[rotund ravine]

Use equals

try that? Not sure

[dry hazel]

reference equality works just fine on enums

[lost matrix]

PotionEffectType is not an enum

[dry hazel]

if it is one that is

[lost matrix]

^^

[dry hazel]

yeah

[rotund ravine]

Seems to be a constant though

So it shooould work

[dry hazel]

not necessarily

[lost matrix]

But i feel like spigot should make sure to reuse those instances instead of creating new ones...

[rotund ravine]

Agreed. Guess not?

[pine forge]

okay thats weird

why is it not an enum

[lost matrix]

Most enums will be replaced by constants in the future because it is needed to reflect the underlying structure mojang is going for.
Everything aims to be data driven, and enums are simply too rigid for that.

[pine forge]

okay hopefully theyll make sure this still works then

[weak meteor]

what

why

-.-

[rotund ravine]

Do it

[pseudo hazel]

can I show images of a minecraft item in chat or on like the scoreboard (using resourcepacks)

[hybrid spoke]

with resource packs you can basically show everything. but you could also use the placeholder api

[pseudo hazel]

so I can also show vanilla items that change texture if you apply another resource pack? like I know you can just create images but I wonder how I would use existing images

idk if what I said makes any sense but I may have solved my problem xD

[river oracle]

I don't think minecraft would natively support this behavior. e.g. if the player changes their resource pack a server would have no clue about this

if you were to create another font, however if YOU as a server were to apply a resource pack something like this could be achieved you'd just need to change the relevant chat textures within your pack

[pseudo hazel]

well yeah but I meant if I can reference a vanilla texture location

[hybrid spoke]

well yes but you dont want to do that. placeholderapi got your back there

[hybrid spoke]

wait what now

[pseudo hazel]

well the items have a model and stuff

which is also what the custom items get

[icy beacon]

Anybody experienced with programming for Android? I'm trying to set sdk level to 30 because that's what my phone is at (Android 11) but apparently Google Play requires that apps target API level 31 or higher. Does this mean that the app will not work on my phone? My minSdk is set to 26, and compileSdk & targetSdk are at 30 (presumably I'll have to set them to 31)

[hybrid spoke]

it will work on your phone and you can deploy it, but to have your app be in play store it requires level 31

[icy beacon]

Yeah so if I set compileSdk and targetSdk to 31, will I still be able to run it on my phone?

I'm asking primarily because my app is currently crashing on start and I'm trying to see whether that could be the reason

[hybrid spoke]

if you dont use newer api yes

[icy beacon]

Interesting, guess I'll have to look out for that

Tyty

[hybrid spoke]

its backward compatible

[hazy parrot]

you dont have webserver to proccess php files

[weak meteor]

ya

maybe

[slate tinsel]

Is it possible to retrieve how high a block is somehow?

[rotund ravine]

Yes

[candid galleon]

getY() ?

[slate tinsel]

How?

[slate tinsel]

Meaned how high the block is

[candid galleon]

:nanithefuck:

what do you mean

how high

like get what drugs its taken?

i dont think blocks have a BAC

[slate tinsel]

sorry if i'm unclear you know blocks have pixels like i want to somehow be able to measure how many pixels a block has or somehow get the height of a block

[rotund ravine]

It’s fairly simple he is just asking how high it is

Like a slab is 0.5 and a full block is 1
