[eternal oxide]

because you will only have Monsters

just loop over teh returned entities

probably just array

[crimson scarab]

cant cast lambda parameter to monster

[lunar schooner]

I need to get the class of java.lang.Byte[], so I thought lets invoke java.lang.Class#arrayType() on java.lang.Byte, it did not like that 🤣

[valid crag]

doesn't know what predicate is so doesn't use it in the getEntities call
uses a predicate in the stream filter call

[eternal oxide]

show the code you are actually trying

[valid crag]

byte[].class

[lunar schooner]

and now in C :/

Thats kindof where I was at lol

[cold tartan]

does anyone know how to load a preset world with a build? like create a new world and put a specific build in it

[crimson scarab]

for (Entity entity : event.getPlayer().getNearbyEntities(32, 32, 32, e -> { e instanceof Monster })) {
                BukkitTask task = new BukkitRunnable() {
                    public void run() {
                        if ((entity instanceof Monster || entity instanceof Player) && !entity.isDead()) {
                            entity.getWorld().strikeLightning(entity.getLocation());
                        }
                    }
                }.runTaskTimer(plugin, 20L, 20L);
            }

sorry once again

[eternal oxide]

why are you using a runnable?

[crimson scarab]

i want a delay

vetween strikes

and you cant freeze the thread

[eternal oxide]

you are creating a runnable for each entity 1 second later, but they all run in the same tick

you are also running a repeating task to fire a single lightning

[valid crag]

don't overload the scheduler

[crimson scarab]

how do you think i implement a delay then?

[valid crag]

instead of scheduling 100 tasks, 1 for each entity, schedule 1 task that processes all 100 entities

it will still be delayed, but less dumb

[eternal oxide]

they get damage by teh trident being dropped do them all at teh same time 1 second delayed

[valid crag]

i think this is the part where i say learn java

[eternal oxide]

you also check for player which will not be a monster

in the predicate you need to do all teh tests you need

a Predicate is simply a boolean test

[crimson scarab]

damn

[lunar schooner]

Ah, seems arrayType is implemented on java.lang.invoke.TypeDescriptor.OfField, darn

[eternal oxide]

so { e instanceof Monster || e instanceof Player}

[lunar schooner]

so err, where would one go about finding the actuall .class files of the java standard library? 🤔 i

[crimson scarab]

so if i want to do 1 task to process all the entites do i need a for loop inside the runnable

[eternal oxide]

final Collection<entity> entities = event.getPlayer().getNearbyEntities(32, 32, 32, e -> { e instanceof Monster || e instanceof Player });
    BukkitTask task = new BukkitRunnable() {
                    public void run() {
                        for (Entity entity : entities) {
                            entity.getWorld().strikeLightning(entity.getLocation());
                        }
                    }
                }.runTask(plugin, 20L);```

or something close

[crimson scarab]

thanks for all your help but im still getting an error here 32, 32, 32, e -> { e instanceof Monster || e instanceof Player });

[eternal oxide]

I've not got an ide up to check it

[crimson scarab]

inconvertible types

[eternal oxide]

a full error might be helpful

[crimson scarab]

Inconvertible types; cannot cast '<lambda parameter>' to 'org.bukkit.entity.Player'

[paper viper]

Just a quick question here. Is it fine to store your library instance as a singleton? (Like passing the instance around inside the framework). Currently i am using dependency injection to pass the instance around my library, but I have seen some people use singletons so that they don't have pass it in when using one of the library classes.

[prime mountain]

so i tried but I really do not like java and kotlin while a lot better, the entire ecosystem is more fragmented than ancient china

[paper viper]

how so

[prime mountain]

can i use mycommands to read and write from files and do math?

so i can cobble together functions and stuff

kinda like bash

[lunar schooner]

I'd say java has a great ecosystem tbh

Much, much better than the likes of C

[lunar schooner]

Yup, you can read files and do match :"D

[prime mountain]

mavan and grandle, java not having a builtin package manager, there being no consistent basic gradle project details that dont assume you've worked with java before

[tulip sky]

how to open the book gui

[prime mountain]

thats just the tip of the iceberg

[lunar schooner]

Maven and Gradle work pretty much interchangeably in terms of dependencies

[paper viper]

Yeah

the Maven central is compatible in Gradle

[lunar schooner]

Sure, it's not as good as say Rust, but, its pretty decent still

[paper viper]

And also a built in package manager isnt necessary if gradle/maven already exists tbh

[tulip sky]

?

[prime mountain]

Ok so where do when im learning about compiling projects, does anyone even bother to tell me what Maven central is and what is from the stock marval, why would i ever choose gradle over mavel, why do the gradle build stuff end in a different suffix, etc

[paper viper]

thats what you have to learn.?

[lunar schooner]

so simply put

mavenCentral is a dependency repository

[prime mountain]

im not asking you

im just saying

[lunar schooner]

Seems pretty straightforward to me though

[prime mountain]

this is very obviously something made to makeup for oracles lack of care for java, and neither of them do a particularly good job at filling the void

[paper viper]

Oracle didnt create gradle or maven

lol

[prime mountain]

........

[paper viper]

Oh wait

yeah nvm

i read that sentence wrong

but yeah I think Oracle didnt bother to do anything about that

[eager tusk]

Hey guys, im searching for a "book gui" when a player joins it opens and theres a text, yk. does anyone know how i do it?

[lunar schooner]

I mean, they dont have the obligation to, so I dont blame them

[paper viper]

Also I feel like Gradle and Maven are very good anyways

we should be glad they exist

and use them

[lunar schooner]

I havent worked with Maven before, but Gradle is amazing

[paper viper]

Mhm

I used both

[lunar schooner]

Going further than Java too, works with CLang too if you want it to

[paper viper]

Gradle is pretty much like its own language

like almost

it tries to act as one

[prime mountain]

Maybe it was because i was diving through a bunch of weird Kotlin API spigot adaptions

[paper viper]

which is what makes it nice

[lunar schooner]

Groovy still scares me, but it works 🤣

[paper viper]

(i mean technically it is cause groovy but you know what i mean)

lol

also the kotlin dsl too is cool

[prime mountain]

well

when i look up dsl

it tells me that a DSL is a

"Digital subscriber line"

[paper viper]

No

[eager tusk]

    broadcast "Welcome to Skript!"```

[prime mountain]

which isn't what that is

[lunar schooner]

:"D

[paper viper]

https://www.google.com/search?q=kotlin+dsl+gradle

take some more effort googling lol

[lunar schooner]

So quick question, again JNI. Why the hell would JNIEnv#new_string() fail? I really cant figure it out, and the error is not at all usefull 🤣

[eager tusk]

how the fuck can you all talk so long about fucking gradle and maven?

[lunar schooner]

too much time lol ¯_(ツ)_/¯

compiling Rust takes a bit, so I've got plenty time in between

[lunar schooner]

...and now it is not failing, T_T what

[eager tusk]

Ok

Can you answer me a question @lunar schooner

[lunar schooner]

sure

[crimson scarab]

how can i check if the player has no blocks above them

[paper viper]

get the location of the player

then loop Y value

get the Block from the location of Y value

if it isnt Air

and etc

[eager tusk]

@How to open a book GUI in the game (that there is information or text)?

[lunar schooner]

or getHighestBlockAt.getY() > playerLoc.getY()

[paper viper]

Completely forgot about that lol

Use that

[lunar schooner]

You'd want to open an Inventory or something like that I'd think

[eager tusk]

no a book

[lunar schooner]

It's been a while since I've toyed with the GUI stuff in Spigot

[bright jasper]

How would i check if a user is between two opposite location objects

[eager tusk]

https://static.wikia.nocookie.net/minecraft_gamepedia/images/e/ed/Book_and_Quill_Writing.png

like this

[bright jasper]

like two locations are points and it makes a box between those points like rise/run and i need to check between that box

[lunar schooner]

Math! Check their X and Z coords compared to the two locations

[eager tusk]

@lunar schooner this

[lunar schooner]

My tip, draw it out

Thatll help you enormously to figure out the steps you need to take to get your result

[tulip sky]

C++ is better than Java, right?

[lunar schooner]

Disagreed

[eager tusk]

https://prnt.sc/1iiwvyw

[bright jasper]

i know about this lmao lemme explain actually

[eager tusk]

TheDutchMC

https://prnt.sc/1iiwvyw

[lunar schooner]

C++ is better at certain things

but Java is better at other things

[quaint mantle]

how do i remove players from the online players counter with the ServerListPingEvent

[eager tusk]

kick them

[bright jasper]

C++ is what you write becomes code, which is better in many scenarios but it leaves room for memory leaks whereas in java its more difficult. A lot of code benefits from the way java does things. If you dont know what you are doing or are not fully attentive to your own code Java code will end up being more performant

[quaint mantle]

not my intention, thanks for the halfassed answer

[bright jasper]

Also extending upon programs is more difficult in C++ since you need dynamic linking whereas in java you simply load classes into the JVM

[eager tusk]

if you need it : p.kickPlayer(""); : d

[lunar schooner]

And this is why I love Rust, it's the best of both worlds! What you write is what you get, but out with the unsafety!

[quaint mantle]

i know how to kick people, stop giving terrible answers

[bright jasper]

Yep i too am a Rust advocate (dynamic linking is also even harder there). But rust does take longer to write a lot of the time

[eager tusk]

Ok my guy

[bright jasper]

and learn, but once you do its way worth

[keen acorn]

        Villager villager = (Villager) e.getPlayer().getWorld().spawnEntity(e.getPlayer().getLocation().add(0, 100, 0), EntityType.VILLAGER);
        villager.setCustomName("Ender Dragon");
        List<MerchantRecipe> merchantRecipeList = new ArrayList<>();
        MerchantRecipe recipe = new MerchantRecipe(new ItemStack(Material.DIAMOND_SWORD), 1);
        recipe.setIngredients(Arrays.asList(new ItemStack(Material.ENDER_EYE, 6)));
        merchantRecipeList.add(recipe);
        villager.setProfession(Villager.Profession.ARMORER);
        villager.setVillagerLevel(1);
        villager.setVillagerType(Villager.Type.SNOW);
        villager.setRecipes(merchantRecipeList);
        villager.setGravity(false);
        villager.setInvisible(true);
        e.getPlayer().openMerchant(villager, true);
``` when this code runs, the villager gui opens for a split second then closes. regular vanilla vilagers work fine. clicking on this summoned villager also makes the GUi close

[lunar schooner]

🤔 I find dynamic linking rather easy actually

using it right now actually! :"D

[bright jasper]

Its a bit harder in the sense that you cant just create a program that dynamically reads a "plugin" and just finds its entry function and injects itself in

[lunar schooner]

oh but you can ^_^

look into the libloading crate

[bright jasper]

🙏 i need to recheck that then

[quaint mantle]

how do i remove players from the online players counter with the ServerListPingEvent, while keeping them online

[lunar schooner]

let me dig through my repos real quick and shoot you an example

[bright jasper]

For video games though i find Rust is a little lacking in terms of libraries. Atm making a 2d platformer in C++. Base engine is written in C++ but a lot of the game functionality in terms of world generators and weapon interactions are done in Lua

[eternal oxide]

Sorry I had to leave for a bit. If you didn;t get it fixed...

final Collection<Entity> entities = event.getPlayer().getWorld().getNearbyEntities(player.getLocation(), 32D, 32D, 32D, (e) -> { return (e instanceof Monster || e instanceof Player); });
        
    BukkitTask task = new BukkitRunnable() {
        public void run() {
            for (Entity entity : entities) {
                entity.getWorld().strikeLightning(entity.getLocation());
            }
        }
    }.runTaskLater(plugin, 20L);```

[bright jasper]

Tried to do it in rust but it was a bit more locking/restrictive and opengl binding crates suck ass

so C++ is still king in gamedev

[tulip sky]

Im a Game dev 😇 😌

[bright jasper]

actually i didnt even use opengl i used BGFX which includes vulkan as well with a platform agnostic api

its really cool

[quaint mantle]

how do i remove players from the online players counter with the ServerListPingEvent, while keeping them online

[lunar schooner]

unsafe {
  let lib = match Library::new(filename.as_ref()) {
    Ok(lib) => lib,
    Err(e) => return Err(e.to_string())
  };

  //We need to stash it in a Vec due to lifetimes, libr MUST outlive plugin
  self.libs.push(lib);
  let lib = self.libs.last().unwrap();

  //Get the _plugin_create function from the library
  let constructor: Symbol<'_, *mut dyn Plugin> = match lib.get(b"_plugin_create") {

  let boxed_raw: *mut dyn Plugin = constructor();

This is all you need to do plugins

on the other side it's an extern C function

[bright jasper]

thats quite a bit easier than i thought actually

ill have to look into that

[crimson scarab]

how to get a delay between loops

[bright jasper]

So here, I need a function that checks in between two opposite locations like a box and it either returns true or false (hence the colors of User(meant to write player but oh well already saved it)). What would be the equation for this

[eternal oxide]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/util/BoundingBox.html

it has a contains method

[bright jasper]

... did not know boundingbox was a thing

thanks

[keen acorn]

for (int i = 0; i < 25; i++) {
  new BukkitRunnable() {
    @Override
    public void run() {
      code
    }
  }.runTaskLater(plugin, delayamount * i);
}

or smth like that

[eternal oxide]

you create a repeating task and process one item per execution

[keen acorn]

shhh its fine

[bright jasper]

how would i make boundingbox ignore height

Y coord

[eternal oxide]

set its Y in both corners to the same

[keen acorn]

if you help me i will send you an emoji of your choice :)

[bright jasper]

ah

so just 0 for both would work

[crimson scarab]

            BukkitTask task = new BukkitRunnable() {

                        if (entity instanceof Monster && (world.getHighestBlockYAt(entity.getLocation()) < entity.getLocation().getY()) && !entity.isDead())
                            entity.getWorld().strikeLightning(entity.getLocation());
                            cancel();
                    }
                }
            }.runTaskTimer(plugin, 50L, 20L);

my issue is that the lightning lags the server

[eternal oxide]

no, has to be the same Y as yoru target location you want to test contains on

[crimson scarab]

and strikes all enemeis at once

[eternal oxide]

not difficult

[keen acorn]

please someone help 🥺

[eternal oxide]

Something like...

        final Entity[] entities = (Entity[]) event.getPlayer().getWorld().getNearbyEntities(player.getLocation(), 32D, 32D, 32D, (e) -> { return (e instanceof Monster || e instanceof Player); }).toArray();
        
        BukkitTask task = new BukkitRunnable() {
            int i = 0;
            public void run() {
                if (i >= entities.length) {
                    cancel();
                    return;
                }

                entities[i].getWorld().strikeLightning(entities[i].getLocation());
                i++
            }
        }.runTaskTimer(plugin, 20L, 20L);```

[bright jasper]

        // Event gets called on flag changes for some reason
        // Do not act on event if player is still on the plot when this happens
        Location location = ((Player) e.getPlotPlayer().getPlatformPlayer()).getLocation();
        if (BoundingBox.of(new Vector(plot.getTopAbs().getX(), plot.getTopAbs().getY(), plot.getTopAbs().getZ()),
                new Vector(plot.getBottomAbs().getX(), plot.getBottomAbs().getY(), plot.getBottomAbs().getZ()))
                .contains(location.getX(), location.getY(), location.getZ())) return;

[wild reef]

Hey is there anyone who could help me with using a Service from an other Plugin I've made? I did the same approach as always but doesn't work anymore, did that changed in 1.17? Just tell me if you need the code

[eternal oxide]

Nothing changed in teh service manager

[wild reef]

well that's how I am doing it rn:
Registering the service in onEnable

Bukkit.getServer().getServicesManager().register(PlayerRegisterService.class, this.registerService, this,
                    ServicePriority.Normal);

And here recieving the service in the other plugin (code also from onEnable)

RegisteredServiceProvider<PlayerRegisterService> provider = Bukkit.getServicesManager()
                .getRegistration(de.schmidi.playerRegistration.services.PlayerRegisterService.class);
        if (provider != null) {
            this.playerRegisterService = provider.getProvider();
        }

But the provider seems always to be null

[crimson scarab]

new error popping up

[wild reef]

The plugin is also running on the server

[crimson scarab]

java.lang.ClassCastException: class [Ljava.lang.Object; cannot be cast to class [Lorg.bukkit.entity.Entity; ([Ljava.lang.Object; is in module java.base of loader 'bootstrap'; [Lorg.bukkit.entity.Entity; is in unnamed module of loader 'app')

[eternal oxide]

yeah I thought it might do that due ot teh cast

its a simple fix. See if you can figure it out 🙂

[wild reef]

do u have any idea about my issue?

[eternal oxide]

remove the cast for starters

[crimson scarab]

ok

now is the toarry and issue

[eternal oxide]

is you second plugin depend on the first?

[quaint mantle]

how can i change the playercount on the ServerListPingEvent, i.e; hiding vanished/hidden players from the server list & playercount

[wild reef]

yea, that's from the plugin.yml:

depend: [PlayerRegistration, Vault]

[eternal oxide]

change the variable to Object[], then cast to Entity in the runnable

[crimson scarab]

ok i;ve got it working a slightly different way

[eternal oxide]

Then IF both plugins are actually on the server and your provider is in fact running, no I see no reason for your issue.

[crimson scarab]

but it is detecting the user me as a entity so can that be removed with predicate

[eternal oxide]

yes

add to the code in the Predicate to test if its you

[wild reef]

that's really bad I also can't find anything :/ also double checked with working examples but couldn't find anything

[crimson scarab]

alright i've got it working but i don't know if it will detect other players

does anyone know how to test another play

[eternal oxide]

what code did you put in teh Predicate to test?

[crimson scarab]

return ((e instanceof Monster || e instanceof Player) && e != event.getPlayer());

[eternal oxide]

ok

then yes it will pick up other players. Only the one dropping the staff will be ignored

[crimson scarab]

ah great

[crude charm]

This is really basic and I'm being dumb rn but how would I get the player I entered into a command e.g /punish bobby would make that say make a new punishment for bobby

[eternal oxide]

I use identical code in my plugins and they all work fine

[wild reef]

I am really confused about this

[eternal oxide]

If you only have name you have to use a name lookup.

with getPlayer or getOfflinePlayer

[crude charm]

ok

[eternal oxide]

You have to be doing something wrong. Like not actually registering

[crude charm]

Can't I just parse it through a constructor?

[bright jasper]

I make do when PlotSquared API breaks and calls events when they shouldnt be

        // Event gets called on flag changes for some reason
        // Do not act on event if player is still on the plot when this happens
        Location location = ((Player) e.getPlotPlayer().getPlatformPlayer()).getLocation();
        if (BoundingBox.of(new Vector(plot.getTopAbs().getX() - 0.5, plot.getTopAbs().getY(), plot.getTopAbs().getZ() - 0.5),
                new Vector(plot.getBottomAbs().getX() + 0.5, plot.getBottomAbs().getY(), plot.getBottomAbs().getZ() + 0.5))
                .contains(location.getX(), location.getY(), location.getZ())) return;

had to do some weird shit like

[eternal oxide]

parse what? you said you have a name and needed a player

[bright jasper]

adding/subtracting 0.5 to a lot of the coords

[crude charm]

An instance of the target it better put

[wild reef]

fun thing is when it seems to be registered, cause when I print all avaible services it is shown as well, but the get doesn't work for some reason

[eternal oxide]

is there a reason you use the fully qualified name in getRegistration?

as you use it in the diamond before.

[wild reef]

just for playing arround, didn't worked before so I thought let's just do something which shouldn't change the outcome

[eternal oxide]

ah

yep, there should only be one class so it should make no difference

[wild reef]

yep, but u know sometimes strange things fix it

[eternal oxide]

yep

[wild reef]

System.out.println("known services: " + Bukkit.getServicesManager().getKnownServices());

this also shows the service

it is contained there, bruh

[eternal oxide]

Is your this.registerService actually an instance of PlayerRegisterService?

[wild reef]

yea

private PlayerRegisterService playerRegisterService;

[eternal oxide]

Then I see no reason for your issue 😦

um, thats different

[wild reef]

RegisteredServiceProvider<PlayerRegisterService> provider = Bukkit.getServicesManager()
                .getRegistration(PlayerRegisterService.class);
        if (provider != null) {
            this.playerRegisterService = provider.getProvider();
        }

just a different variable name in the plugins

its the same var name in each plugin

[eternal oxide]

ok, but just so long as the instance you are registering this.registerService is the correct class

[crude charm]

How can I get the first argument (or zero) from outside the command?

[wild reef]

ye it is

[eternal oxide]

k

[eternal oxide]

dependency injection. you pass it to whatever method needs it

[wild reef]

@eternal oxide

I really don't get it

[eternal oxide]

um, null?

[lusty cipher]

How can I get a list of all resources in my plugin?

[wild reef]

null comes from:

System.out.println(Bukkit.getServicesManager()
                .getRegistration(PlayerRegisterService.class));

[lusty cipher]

Oh I just thought of a genius idea to get a list of resources

[eternal oxide]

You must have some instancing issue. like dodgy imports or something

do both of your plugins use different packages?

you have no overlap?

[wild reef]

import de.schmidi.playerRegistration.services.PlayerRegisterService;
----
package de.schmidi.playerRegistration.services;

packages also match

[crude charm]

How would I go about this? I need these fields in the method.

they cant be declared outside it

[eternal oxide]

yep, I was just wondering if you have (by mistake) created a duplicate package/class locally in yoru plugin

[bright quartz]

any idea how i could replicate the spectator mode flight but without the noclip part?

[sullen dome]

is it possible to disable only THIS error when running an application? there's no way to prevent it, and imo it's annoying that it always opens a new tab, where it jumps to

[bright quartz]

just a way to make a player instantly transferred into flight and locked in flight (unable to double press spacebar to go out)

[sullen dome]

isn't the spectator flight the same as creative?

ah nvm, i see

[bright quartz]

spectators cannot double press space to get out of flight

they get locked in flight

[sullen dome]

yeah i see

you could set them flight again, when they stop flying

if thats possible with #setFlying

[lusty cipher]

I assume the top half of a door is placed 1 tick after the other?

[sullen dome]

probably

notexture cool cool cool

[bright quartz]

also, i feel i should not

player.setFlying(); does not actually set them into the fly mode

it will most definitely stop you from flying if you are flying

but if you're on the ground it will not transfer you into flight mode immediately

it will only do that if you jump

wait what if i just teleport the player like one block up i think that would work

[unique halo]

how do i hit a entity through spigot code, i have the entity , and player
i tried

( (CraftEntity) e ).getHandle().damageEntity( DamageSource.playerAttack( (EntityHuman) p ), 1.0f);

but i just get errors

spigot 1.8.8 btw

[digital plinth]

never seen this error

wierd

this kind of error dont show up even when i frgot the command section in plugin yml

[eternal oxide]

Your command is not in your plugin.yml

[digital plinth]

but it is in it

[eternal oxide]

nope

[eternal oxide]

that error says the command you tried to retrieve is not there

[digital plinth]

id i palce the yml in the wrong place?

[sullen dome]

then i guess there is no serverside way

but idk exactly

[digital plinth]

ik but i have no idea what is causing it

[eternal oxide]

plugin.yml goes in resources

[digital plinth]

i dont remember such error show up when i forget stuff in yml

oh

okay thx

[digital plinth]

i think the flying animation is like a packet thing

dream did make the minecrfat but always flying plugin

try cracking them open i suppose

[mellow beacon]

Can anyone help me figure out why this is red and why no essentials commands or chat prefixes are working?

[bright quartz]

if(player.getInventory().getItemInMainHand().getItemMeta().equals(ItemData.SPIRIT_STAFF.getItemMeta())) any idea why this isn't working? if i have my code right, the item meta of the item in the main hand should be identical to the itemmeta for the spirit staff because they are the exact same item

okay looking at my console i get the error Caused by: java.lang.NoSuchMethodError: 'org.bukkit.inventory.ItemStack org.bukkit.inventory.PlayerInventory.getItemInMainHand()'

[lusty cipher]

@mellow beacon Essentials failed to enable. Look into your console, there's probably some error message there.

my bad in java

[crude charm]

can someone plz help me

[quaint mantle]

just make plugin final

private final Plugin plugin;

    final Plugin p = this.plugin;
    new Lambda() -> {
        //p.method()
    }.run();
}

[proud basin]

I think it's something like Bukkit.getServer().getWorld("world").setThundering();

[lusty cipher]

yes it is ^

[proud basin]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/World.html#setThundering(boolean)

yea

[crude charm]

I cant

[quaint mantle]

?

[crude charm]

1 sec let me find the bloody class out of 500 lmfao

[lusty cipher]

final Plugin p = this.plugin; this is the relevant line

not the field above

you just have to create a copy of all variables as final variables before running the lambda method

[crude charm]

unless im blind I believe I dont have to get an instance of main, my util does that

[quaint mantle]

then why are you complaining

[lusty cipher]

The same applies for player and args btw

[lusty cipher]

It's just basically you should do this with all variables that you use in lambdas

[quaint mantle]

what are you trying to do?

we've already said everything you need to know

[crude charm]

parse an instance of the "target" to another class

but idk how to get an instance of the argument as I need stuff inside the method to define it

[quaint mantle]

[compact wigeon]

Is there any good way (non-janky) to get around PlayerInteractEvent firing twice in 1.8.8 when right clicking certain intractable blocks such as cobble walls, fences, and crafting tables?

[quaint mantle]

Try using System.currentTimeMillis

you can compare them, if its under the cooldown time you ignore the event

[compact wigeon]

Thanks!

[lusty cipher]

why would one use 1.8.8 over 1.8.9 wtf

[unique halo]

why is there like a cooldown or something for e.damage?, when i e.damage someone, e.damage wont work again if i do it like 0.1 seconds later

Hey i was wondering if this is possible with Pterodactyl?

Start a server in minecraft and a batch file will run to create that server on pterodactyl panel and then assign the ip and port(be a port from before so i don't got to open up tons of ports so for instance i log on my port is 25566 then quit and you login and take that port). Then all the files will go to the server that you just created. After everyone is off the server which ill just check that with bungeecord. Shut down and save the files then remove them. For someone else to use.

or the best way to just do it

[fading lake]

If you try to set a player flying to true before they're loaded in, does it have a chance of not setting flight ingame, but spigot thinking it is?

cause spigots giving me the wrong value for if a player is flying and I'm really confused

[fading lake]

nope, even after 10 seconds it still doesn't activate

[lost matrix]

PlayerLoginEvent is a bit strange. You should delay any action that uses the logging in Player by one or two ticks.

[fading lake]

I tried delaying it by 200 ticks just to be sure, and it lead to the same issue, it just seems like the players flight and the spigot variable are unlinked for some reason

Printing isFlying returns true which is whats stumping me, even when the player isn't flying (allowflight is on), but fall dmg is still negated

[lost matrix]

Show some code pls. If you delayed it by 10 secs and it still doesnt work then your logic might be faulty.

Or spigot is acting weird.

[fading lake]

@EventHandler
private void onPlayerJoin(PlayerJoinEvent event) {
    Player player = event.getPlayer();
    Bukkit.getLogger().severe("1");
    if (player.hasPermission("hub.flight.auto")) {
        Bukkit.getLogger().severe("2");
        new BukkitRunnable() {
            @Override
            public void run() {
                player.setAllowFlight(true);
                player.setFlying(true);
                Bukkit.getLogger().severe("attempted change");
            }
        }.runTaskLater(HubCore.getCore(), 200);
    }    
}

Prints:
1
2
attempted change (after 10 secs)

printing isFlying on a timer loop is true until the player double jumps into flight, then disables it

[young knoll]

Are they on the ground

[fading lake]

Yes

[lost matrix]

What exactly doesnt work. What do you expect to happen and what is actually happening

[fading lake]

what I want it to do, is check if the player has that permission, and if they do, immediately launch them into flight when they join (not making them turn it on themselves by jumping into it, it already being on etc)

[young knoll]

Send them into the air first

[fading lake]

oh is it that simple lol

[young knoll]

The game disables flight when you touch the ground

And spigot may not notice that, might be a client side thing

[lost matrix]

If they stand on the ground then flying is disabled

[fading lake]

oh that makes sense, let me try it

[lost matrix]

Are you willing to use NMS? Because if its client side you can try and send a PacketPlayOutAbilities packet

But its most likely the fact that they are grounded

[fading lake]

yeah I'm fine using NMS, sorry give me a sec, servers acting weird

[lost matrix]

((CraftPlayer) player).getHandle().updateAbilities();
Try calling this manually

[young knoll]

It seems weird spigot thinks they are flying and the client doesn’t

Unless something client side is going on

[fading lake]

calling this seemed to fix it, as for changing the Y level on its own, it didn't seem to affect it, thank you ❤️

[fading lake]

I know, considering thats the method that worked and is called straight after the handles flight is changed in CraftPlayer

[young knoll]

Might be because you are calling setAllowFlight too

[torn shuttle]

finally, my rewrite is stable

boys, it feels good

[digital plinth]

Do you know how many ms are between the two events? Player can also click really quickly twice

[digital plinth]

its u

...

[lost matrix]

Which two events?
Usually about 50m if the user manages to send two packets fast enough

[young knoll]

Print out the current time and compare

It probably varies

[digital plinth]

roger

[digital plinth]

main and off hand player interact

[lost matrix]

Just use the next line char \n

[young knoll]

Can’t you just check which hand is being used in that case

[lost matrix]

They are fired on the same tick.

If no events hook into them then it way under 0.01ms but if some Listeners tinker with the event then the discrepancy rises.

But you can get the hand that is related to the event from within it.

[digital plinth]

oh so 50ms

[lost matrix]

Only if you speak of spam clicking.

[digital plinth]

so this is how datapacks work

kinda weird

XD i think you are better off learning java and making plugins tbh

[lost matrix]

  @EventHandler
  public void onInteract(final PlayerInteractEvent event) {
    final Player player = event.getPlayer();
    final EquipmentSlot hand = event.getHand();
    if (hand == EquipmentSlot.HAND) {
      player.sendMessage("This is your main hand event.");
    } else {
      player.sendMessage("This is your off hand event.");
    }
  }

[digital plinth]

thx

[lost matrix]

I also went ahead and measured the delta of those two events

so around 50us - 80us on my machine

[summer scroll]

idk if this is helpful but the main hand will be called first, i remember do some testing before

just a fun fact ig

@raw coral https://github.com/CodedRed-Spigot/DenyTravel/blob/main/DenyTravel/src/dev/codedred/denytravel/events/EntityTravelEvent.java

isnt it !=?

or are you talking about something else

Hello, it is possible to make a Miencraft plugin as a web server?
Like, if someone dies, to be placed on a webpage that is created by the plugin?
Sorry if I sound dumb, I'm very new with those things xD
You guys here are the experts.

[hybrid spoke]

of course its possible

but your plugin wouldnt be a web server, it would just communicate with a web server

[tribal holly]

is it possible to summon an trident and apply it a vector like arrow ?

[hybrid spoke]

why shouldnt that be possible

[tribal holly]

i know that's possible cause it extending arrow

but can't find doc for doing it

[hybrid spoke]

so you just wanna push the trident, right?

[tribal holly]

i wanna summon it at a location and apply it a custom vector

to make like a "trident rain"

and there's not attached to a plyer and cannot be pickable

[hybrid spoke]

spawning them already forces them to fall down

[formal warren]

How is the Dynmap working?

[tribal holly]

how do you spawn them ?

[hybrid spoke]

and how would you like to apply a vector? do you mean setting the velocity?

[hybrid spoke]

World#spawnEntity

[tribal holly]

well kinda dump i'm

[hybrid spoke]

A Google Maps-like map for your Minecraft server that can be viewed in a browser. Easy to set up when making use of Dynmap's integrated webserver which works out-of-the-box, while also available to be integrated into existing websites running on Apache and the like. Dynmap can render your worlds using different renderers, some suitable for performance, some for high detail.

since i didn't looked at the source code, if there is any public, i can't tell you what it does exactly. probably just doing some magical stuff and sending it to the webserver so it can display it

[lost matrix]

Dynmap loads every chunk one by one and makes a snapshot of it.
The 2D view is easily rendered by just getting the highest block on every x/z point in the chunk and then using the minecraft texture to render
a simple top down view.

The orthographic view on the other hand is a bit more complex to display as you need a proper 3D framework. A lot of it is just html, css and JavaScript.

[formal warren]

But Dynmap is working as a server, right? I mean, after I activate the plugin I can see the map in browser. So it doesn't communicate with someone externally, only itself and the server

[opal juniper]

myeah

it hosts the server in a new thread or whatever

as to not affect the mc server too much

[lost matrix]

Dynmap starts a web server

[formal warren]

I see, thanks you for the time and the informations.
Programming is so haard.

[lost matrix]

Just looked at github. They start a simple jetty server to provide the website.

[quaint mantle]

Hello! I am trying to cancel item frames rotations on right click. Do you have idea?

This is what I tried:

    @EventHandler(ignoreCancelled = true)
    public void onPlayerRotateFurniture(PlayerInteractAtEntityEvent event) {
        Bukkit.broadcastMessage("OKAY");
        Bukkit.broadcastMessage("OKAYa: " + event.getRightClicked().getPersistentDataContainer().has(FURNITURE_KEY, PersistentDataType.STRING));
        if (event.getRightClicked() instanceof ItemFrame
                && event.getRightClicked().getPersistentDataContainer().has(FURNITURE_KEY, PersistentDataType.STRING)) {
            Bukkit.broadcastMessage("OKAY2");
            event.setCancelled(true);
        }
    }```

[opal juniper]

PlayerInteractEvent

[quaint mantle]

it is triggered, I get the 3 logs, but it is not cancelled

[quaint mantle]

with ray tracing ?

[opal juniper]

mmm lemme see what you have done

Are you sure it is ItemFrame

[quaint mantle]

yes since it is detected

[dense goblet]

I didn't need raytracing to achieve it, it was a side-effect of cancelling interact events in general

[quaint mantle]

I mean, I get the logs when I right click on it

[opal juniper]

no i mean instanceof ItemFrame

sometimes things have stupid names

[quaint mantle]

yeah but I don't want to cancel all interact events

just the one that target item frames

[quaint mantle]

I don't understand

I get my "OKAY2" when I right click the item frame

so the right click on the item frame is detected

[opal juniper]

Remove the instanceof ItemFrame thing

cause

[quaint mantle]

why?

it won't change anything

[opal juniper]

only ur itemframes will have the data anyways

and it may be the issue

[quaint mantle]

No it can't be the issue

[dense goblet]

@quaint mantle

public void onItemUsedOnEntity(PlayerInteractEntityEvent e) {
        if(e.getRightClicked() instanceof ItemFrame)
            <code>
}

[quaint mantle]

since I get the "OKAY2" log

[opal juniper]

oh right

sorry

[quaint mantle]

no problems

https://www.spigotmc.org/resources/disable-item-frame-rotation.33134/

I don't understand, they also use that event

bruh

I'll try with spigot instead of paper

[dense goblet]

What is not working for you?

You're using PlayerInteractAtEntityEvent but I used PlayerInteractEntityEvent

Idk the difference but might be the reason

Docs say it's the same but with the location, though they advise to listen to the other version (without At)

[quaint mantle]

good idea

Great job @dense goblet , that was the issue!

[dense goblet]

Nice!

[waxen plaza]

how is it called when a player is asked to say something in chat and the plugin gets the input without it being sent to chat?

[chrome beacon]

Listen to the chat event and cancel it

[waxen plaza]

thanks. 🙂

[grim ice]

is Developing in paper better, or worse? I use JDK 8

[dense goblet]

If you need features of paper (like an AI api) then use paper

Otherwise just develop for spigot api as all spigot plugins work on paper

But not all paper plugins work on spigot

[grim ice]

Oh okay

[dense goblet]

There is I think PaperAPI which allows you to use paper features if the server is running on paper, and otherwise it uses the spigot version

Like async chunkloading

With paper it will do async, with spigot it will do sync

Small help around one thing
Is it good idead to block player i asyncpreloginevent
And load there data from mysql

So they are stuck in loading screen

Until data is retrived from mysql

[undone axle]

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

[chrome beacon]

No

[valid crag]

yes

if the alternative is to block the join event

or if the alternative is to not have the player's data ready for when it's needed

[hybrid spoke]

or just let them join and freeze them until their data has been loaded

[valid crag]

and the server, too, if someone still wants to read the data

by the time the player is in the game their data should all be loaded and proper

anything else will run into issues when multiple plugins are at play

imagine for example an economy plugin that reported 0 for player's balances for the first 3 seconds they're online

when this code runs, the villager gui opens for a split second then closes. regular vanilla vilagers work fine. clicking on this summoned villager also makes the GUi close

(please ping on response)

[wary harness]

so my best options will be

[hybrid spoke]

for(entityType) {

  if(type.equals(entityType.name)) { yes }
}

[wary harness]

to save on every transaction

so if player switches server

data is already saved

and loaded

proparly on async pre login event

[hybrid spoke]

save it in an interval of X minutes and if they leave

[wary harness]

mysql know to be slow on some people machines

and then u get in problems like A server didn't save yet and player switched to server B

and loaded old balance before saving was finished on Server A

and that happens for many people because there servers are on different machines

[hybrid spoke]

and because of that you are saving the players data when he leaves the server

is anyone going to help me

[quaint mantle]

hey how do i download a bukkit development build for making plugins

[keen acorn]

bukkit is outdated

use paper instead

papermc.io/downloads

[quaint mantle]

what if i want to update a bukkit plugin?

[keen acorn]

you can compile it with spigot

[topaz moon]

bukkit can run with spigot and paper

[hybrid spoke]

you either have to delay it for a second so the server can recognize the villager first or it is opening the inventory twice

[quaint mantle]

alright thanks ill try

[wary harness]

well that is problem with saving on leave

event

mysql will not manage to save in time

[keen acorn]

opening the inventory twice? hmm

[wary harness]

and server b will load old amount

[hybrid spoke]

yeah if you click on him it will open his and your inventory

[keen acorn]

its running the event twice because i am in creative mode i think

[hybrid spoke]

it should unless you are not doing any expensive operations to save it. otherwise, if they switch the server, support bungee

[hybrid spoke]

what event

[keen acorn]

interactatentity

[hybrid spoke]

there we have the issue

cancel the event

ofc its not working

[wary harness]

what would u do by supporting bungee

[summer scroll]

Probably because you have two hands now.

[wary harness]

send amount of tokens from server a to b

thru messaging chanel

[hybrid spoke]

oh yeah and the second hand

[keen acorn]

@hybrid spoke i am not checking if they are clicking a villager, I am checking if they are clicking an ender dragon

[wary harness]

what is your problem

interect event goes 2 times

[hybrid spoke]

we cant see that from your code

listen for the hand

just like aglerr said

[summer scroll]

The event fires twice because you have two hands, so check If the hand is off hand, return.

[severe marsh]

Am I supposed to enter a name of plugin here? https://prnt.sc/1io6oh0

[keen acorn]

ah thanks

[hybrid spoke]

the instance of your plugin

[summer scroll]

the reference of your main class

[hybrid spoke]

either getting it by singleton or DI

[severe marsh]

How?

[hardy swan]

||Bukkit.getPluginManager().getPlugin("lmao");||

[severe marsh]

thanks

[hardy swan]

no don't quote me

that's not what they meant

although I also don't see a problem with doing that

[summer scroll]

cmon xd

[opal juniper]

smh no dont use this

[summer scroll]

bad guy

[hybrid spoke]

or go this way

public static final String plugin-name;

public void onEnable() {

  plugin-name = "YOUR_PLUGIN_NAME";
}

public void getPlugin-Name() {
  return plugin-name;
}

[hardy swan]

ok, I don't see a reason for dependency injection if the class doesn't even need any aspect of the instance instead of just passing it around like volleyball (e.g. using it for BukkitScheduler#runTask). But I also object having a singleton because it is illogical design-wise.

oh, he just needed the name?

[summer scroll]

no xd

he needs the instance of the main class to use scheduler

[hardy swan]

oh okk lol

[hybrid spoke]

i thought imma getting shittalked

because everything was wrong about this

but okay nvm

[indigo crypt]

Back to my problem:

    Zombie ent = (Zombie) mob;
}else if(type.equals("SKELETON")) {
    Skeleton ent = (Skeleton) mob;
}
// Looping to make variable
ent.justCallIt(true);```
I don't know how to explain it, I want loop condition to make some variable, and call it

like this code

[hybrid spoke]

didnt i just

gave you the solution?

[hardy swan]

type.equals("ZOMBIE") looks wrong

it should be around the lines of mob instanceof Zombie

[indigo crypt]

its not what i mean

[hybrid spoke]

you wanted to have a loop for your type.equals thing

to avoid calling it for every entity

[indigo crypt]

maybe yes

[hybrid spoke]

otherwise EntityType#valueOf(type) is also a solution

and checking with instanceof afterwards

instead of an equal check

[ancient plank]

sorry chief, I sleep at 9pm my time and it was 11pm my time when u pinged me

[indigo crypt]

nononono, its not i mean

ohh god, i dont know how to explain it

[hybrid spoke]

visualize it

[keen acorn]

ok i got it fixed with the double event thing ty bye

[indigo crypt]

normal code to use
Zombie entity = (Zombie) someEntity
and
Skeleton entity = (Skeleton) someEntity
and i want to make loop like this

  // make entity as Zombie
  Zombie entity = (Zombie) someEntity;
} else if(SomeString.equals("skele")){
  // make entity as Skeleton
  Skeleton entity = (Skeleton) someEntity;
}
// example output SomeString is jombie
entity.execute();```
are you understand

[valid crag]

for (entitytype et : entitytype.values()) if et.getentityclass().isinstance(mob) et.getentityclass().cast(mob)

literally no point in that though, that's not how java works

[indigo crypt]

wait

[maiden briar]

Does anyone know what (int) aInteger %2 does?

[valid crag]

takes mod 2 of ainteger

[maiden briar]

I don't understand

Will it take 50%?

[hybrid spoke]

but thats

not what he meant

[valid crag]

that takes mod 50 of ainteger

[indigo crypt]

yes, i just try

[maiden briar]

So if it is 100 it returns 50?

[valid crag]

x % 2 divides x by 2 and returns the remainder

100 % 50 returns 0

because 100 is divided by 50 evenly to 2

with no remainder

[maiden briar]

Ah thx

[valid crag]

google modulus

this is basic math

[maiden briar]

Ok

[tacit drift]

can i get rid of

"Unknown map"?

[valid crag]

probably not

[tacit drift]

f

[indigo crypt]

maybe if spigot have like

String some = "Zombie";
// make variable as entity
Entity.valueOf("Zombie") ent = (Entity.valueOf("Zombie")) someEntity;
// i mean output like
Zombie ent = (Zombie) someEntity

// and if string is "Skeleton"
// output is
Skeleton ent = (Skeleton) someEntity;```
Are you understand?

[valid crag]

literally what

[severe marsh]

I do understand what's the issue, but I don't know how to fix it.. https://prnt.sc/1iog9yd

[hybrid spoke]

what

Entity.valueOf("Zombie") ent = (Entity.valueOf("Zombie")) someEntity; ?

[valid crag]

learn java'

[chrome beacon]

You can't change that timer inside the runnable

[valid crag]

java is strongly typed

[severe marsh]

How can I make countdown then?

[hybrid spoke]

AtomicInteger

[valid crag]

which means that you cannot dynamically define the type of a variable

[hybrid spoke]

or dont make it a local var

[valid crag]

you can only directly declare it as a Zombie or a Skeleton or whatever

[severe marsh]

hmmm alright ty

[valid crag]

the best you can do is generic type parameters and shit but that is far from what you want

[indigo crypt]

i dont know how to explain it. i want make some LivingEntity variable as Zombie or Skeleton
LivingEntity mob = (LivingEntity) mlocs.getWorld().spawnEntity(someLocation, EntityType.ZOMBIE);
and i want to make living entity as Zombie
normaly i use
Zombie ent = (Zombie) mob;
and use ent variable

and how to i make it to i check if mob type is skeleton and make mob as skeleton like this:
Skeleton ent = (Skeleton) mob;
someone understand it?

[valid crag]

use World::spawn

instead of spawnEntity

and pass the entity class instead of entity type

and it'll return an instance of that class and you don't need to cast or think about anything

[indigo crypt]

hmmm, wait. i will try it

[indigo crypt]

nah, i mean. how to i pass entity class according condition

[quaint mantle]

wtf, use switch/case everywhere

why if, when variants more than 1?

[valid crag]

it would be helpful if you mentioned what the fuck you were doing

[indigo crypt]

yes

[valid crag]

so far all we've heard has been incomprehensible babbling about loops and skeletons

what are you doing

[indigo crypt]

i want to pass entity class to some mob according condition, if string == jombie
pass entity class Zombie, and if string == some mob, pass entity class someMob

[indigo crypt]

i think you understand what i mean

[valid crag]

that is your attempted solution

but what are you actually doing

what are you trying to achieve

[indigo crypt]

?paste

[undone axle]

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

[hybrid spoke]

couldnt get an answer either

[dense goblet]

Why do you need that

[indigo crypt]

okay, ihave some code
https://paste.md-5.net/ulecojiqez.cs

i want shorten or make it effective with loop

how to do that

[hybrid spoke]

it seems to me

that you don't even have to cast

[dense goblet]

You want different behaviour for every mob right

[hybrid spoke]

just use the superclass LivingEntity

[valid crag]

learn oop

a for loop will not help you here

[hybrid spoke]

it will make it cleaner for sure

but he should also split it in several methods

[valid crag]

instead of passing a string to this function, you should pass an object that defines the behavior you're stacking in here

this is a textbook example of oop being done wrong

[indigo crypt]

what i have to use

[indigo crypt]

yes

[quaint mantle]

how do i check for errors in eclipse

[indigo crypt]

maybe you can give a little example. my brain has exploded after explaining

[dense goblet]

Then you should use a hashmap between whatever you use to identify a mob and an object which applies the desired changes

[indigo crypt]

oh yeah, makes sense

[dense goblet]

Also try to re-use code where possible

Instead of having lots of similar lines

[indigo crypt]

ohh yeah, i can't figure it

[indigo crypt]

give me a little example

[dense goblet]

For example you are using very similar code for setting the name of the mob

Just have one function for that and make them all use it

[quaint mantle]

hey if im updating a plugin and if i just add the latest spigot in the build path do i need to add the previous spigots the plugin was built with

No

Take a look at how we do it

[grim ice]

can someone give me an example instead of psuedocode?

[hybrid spoke]

example of what

the

That's real code they have just it's a cleaner format for return statements that depend on conditions

[chrome beacon]

That's not psuedocode

[grim ice]

whatever

i dont get it tho

[summer scroll]

it's basically simplify the code

condition is boolean

[dusk flicker]

Do you understand the top if statement?

[hybrid spoke]

public SpawnTask createAFuckingSpawnTask() {
  return (spawnTaskList.hasSpace() ? new SpawnTask() : null);
}
``` or whatever

can be understood as

return a new SpawnTask if the list has space and if not return nothing (null (null isnt really nothing))

[severe marsh]

How do I cancel Runnable task?

[dusk flicker]

Basically a condition followed by a ? Operator is the same thing as an if statement, and the following param will be sent if it is true and the operator after : is what to return if it is false

boolean ? true : false;

If you use IntelliJ it will auto suggest improvements to your code that use those statements

How do I safely get the UUID of a player (who has to have connected to the server atleast once in the past, but may or may not be currently online) from their playername in Bungeecord? I'm trying to write an economy plugin when players are stored in a database by their UUID and I'm wanting commands such as /bal [player] meaning I'd need to convert the entered playername to the respective UUID (or find tat no such player exists in which case I would return an error to the player)

[proud basin]

what if the player wants to type in their uuid instead

[high pewter]

I could make that an option I suppose but I highly, highly doubt all players (or even a few) will want to do that

[gleaming grove]

Guys i found that since 1.17 version all of packets class are in "net.minecraft.network.protocol.game" instead of "net.minecraft.server.[verision].[className] . Does it mean we no longer need to care about NMS reflections?

[dusk flicker]

they no longer include version's

[gleaming grove]

yea 😄

[dusk flicker]

Some classes may be in other packages so just know that, if I recall it follows Mojang's packages now

[gleaming grove]

what about bukkit, it as well remove verions from packet path?

[dusk flicker]

Like if a user is running bukkit?

Should be the same due to it being maintained by Spigot

[gleaming grove]

this is my old code to get bukkit class, so now i not longer need to include version?

[dusk flicker]

Im not sure on that, id check but I dont got a jar right now

I tried making an event that cancels BlockPlaceEvent when you place a player head, tried this and whenever i put heads on the side of a block, it doesnt work the block gets placed. Any way to fix this? Heres my code

public class block_place implements Listener {

    @EventHandler
    public void onItemPlace(BlockPlaceEvent event) {
        Player player = event.getPlayer();
        if (event.getBlockPlaced().getType() == Material.PLAYER_HEAD) {
            event.setCancelled(true);
        }
    }
}

[hybrid spoke]

because then its a PLAYER_WALL_HEAD
also make sure to follow the java naming conventions

        locations.add(start.clone().add(line));
        line.normalize();
    }
    return locations;
}

Anyone know why this doesn't work - i am trying to get a list of locations on a line

you out here roasting him

[quaint mantle]

😢

it's okay its a weird way to name classes ik

[opal juniper]

thats how python names stuff and i hate it

before you judge this is godciphers code

so

blame him

ye

i forget, is it:
line.normalize();
or
line = line.normalize();

the former right?

oke

okk

    private List<Location> line(Location start, Location end, double distanceBetweenLocations) {

        List<Location> locations = new ArrayList<>();
        Vector line = end.toVector().subtract(start.toVector());
        line.normalize();
        line.multiply(distanceBetweenLocations);
        for(int i = 0; i < 50; i++) {
            locations.add(start.add(line.multiply(i)));
        }
        return locations;
    }

or have i misunderstood

[gleaming grove]

guys do you know some good launcher? i need to test plugin on 2 accounts

[opal juniper]

ok

i want a size of 50

myeah ok

thanks

mhm

[lost matrix]

Location is mutable right? So you need to clone it if you want to have multiple ones.
You can also try 2 approaches to determine the end condition.

1. Calculate the number of iterations need beforehand
2. Check the current lenght.squared against the full distance.squared
   The first one is faster.

[opal juniper]

turn it to offline mode and then get something like https://mc-launcher.com/special/minecraft.html

obviously i never said that...

[gleaming grove]

it could be in online mode i have mutiple accounts

[opal juniper]

oh well it works anyways with actual accounts

ok

[gleaming grove]

lets see if my account will be stolen

[opal juniper]

myeah i always just use a fake one

sorry i got sidetracked by the venom trailer

im back

[lost matrix]

This would be my approach:

  private List<Location> line(final Location start, final Location end, final double distanceBetweenLocations) {
    final List<Location> locations = new ArrayList<>();
    final Vector fullLine = end.toVector().subtract(start.toVector());
    final double fullLength = fullLine.length();
    final Vector deltaLine = fullLine.clone().normalize().multiply(distanceBetweenLocations);
    final int increments = (int) (fullLength / distanceBetweenLocations);
    locations.add(start);
    for (int i = 0; i < increments; i++) {
      final Location nextLocation = locations.get(locations.size() - 1).clone().add(deltaLine);
      locations.add(nextLocation);
    }
    locations.add(end);
    return locations;
  }

[opal juniper]

Hmm

yeah that looks good

thanks

[lost matrix]

.

[opal juniper]

let me test it

hehhehe

[hybrid spoke]

another discord server in my list for just one emoji

[opal juniper]

same

uhh

[lost matrix]

No. It gives you N locations depending on the delta you specified

[opal juniper]

Yeah that should be good

[lost matrix]

Yeah this works too

  private List<Location> line(final Location start, final Location end, final double distanceBetweenLocations) {
    final Vector fullLine = end.toVector().subtract(start.toVector());
    final double fullLength = fullLine.length();
    final Vector deltaLine = fullLine.clone().normalize().multiply(distanceBetweenLocations);
    final int increments = (int) (fullLength / distanceBetweenLocations);
    final List<Location> locations = new ArrayList<>(increments);
    locations.add(start);
    for (int i = 0; i < increments; i++) {
      final Location nextLocation = locations.get(locations.size() - 1).clone().add(deltaLine);
      locations.add(nextLocation);
    }
    locations.add(end);
    return locations;
  }

But it doesnt make a huge dif

Wait. Does an ArrayList with initial size have null entries?

Hi, i'm trying create packetplayoutentitymetadata using reflections, so i have one question, it is ok?

        Class c = Class.forName("net.minecraft.network.protocol.game.PacketPlayOutEntityMetadata");
        Class types[] = new Class[3];
        types[0] = Class.forName("java.lang.Integer");
        types[1] = Class.forName("net.minecraft.network.syncher.DataWatcher");
        types[2] = Class.forName("java.lang.Boolean");

        Constructor constructor = c.getConstructor(types);

        Object argList[] = new Object[3];
        argList[0] = armorStand.getId();
        argList[1] = armorStand.getDataWatcher();
        argList[2] = true;

        Object object = constructor.newInstance(argList);```

[lost matrix]

Ofc because the backing array is copied with System.arrayCopy. Just was confused if giving an initial size would change the element count. Btw can you specify a custom growth function in default java lists? Never checked

Really? So changes on the list are reflected in the array?

Ew

Nice. Naming is on point.

[lost matrix]

Yes this looks right. Didnt check the argument types but the reflection part looks right.
Make sure you cache reflection Objects as they can get really costly.

Ah interesting

[left swift]

ok, then if that's okay, I'd like to send this as a packet, ie should I cast object to a packet?

[gleaming grove]

@left swift What code do you use to send a packet to player?

[left swift]

((CraftPlayer) p).getHandle().b.sendPacket(packet);

[lost matrix]

If you use reflections like that then you probably want to go the full mile instead of using NMS directly after using it via reflections.

[lost matrix]

Why do you use reflections then anyways if you use NMS on your classpath like that?

[gleaming grove]

Guys do you know what am i doing wrong?

[lost matrix]

Server and development versions dont match

[left swift]

I wanted to use reflection because when I used the normal PacketPlayOutEntityMetadata nms class I was getting this error

is there any other way to fix this?

ugh, I generally get the same error with these nms classes :/ what to do about it?

import net.minecraft.network.protocol.game.PacketPlayOutEntityMetadata;
import net.minecraft.network.protocol.game.PacketPlayOutMount;
import net.minecraft.network.protocol.game.PacketPlayOutSpawnEntity;```

[lost matrix]

This doesnt work?

  public void sendNMSDataWatcherPacket(final Entity bukkitEntity, final Player receivingPlayer, final boolean forceUpdate) {
    final net.minecraft.world.entity.Entity nmsEntity = ((CraftEntity) bukkitEntity).getHandle();
    final PacketPlayOutEntityMetadata packet = new PacketPlayOutEntityMetadata(nmsEntity.getId(), nmsEntity.getDataWatcher(), forceUpdate);
    ((CraftPlayer) receivingPlayer).getHandle().b.sendPacket(packet);
  }

thx i used spigot1_17.jar dependency instead of 1_17_1 that sever uses
