yeah you're right, first problem was probably mismatching name

#

but then they fixed the name but removed the "extend JavaPlugin" part lol

bro im using a forge instance and its still not logging shit

#

at least the error is mapped

tender shard May 12, 2022, 4:54 PM

#

they probably don't even know basic java so, if I was you, I'd send them ?learnjava instead, otherwise you're probably just wasting your time lol

#

yep

#

well

#

in 90% of cases

#

erm yeah sure

#

you mean for stuff like command completion or what?

glossy venture May 12, 2022, 4:57 PM

#

do something like

tender shard May 12, 2022, 4:57 PM

so you want the actual command executor to do async stuff?

Is it possible to cancel all the scheduled tasks that were scheduled by my plugin? (without having to save the id)

tender shard May 12, 2022, 4:57 PM

#

crude loom Is it possible to cancel all the scheduled tasks that were scheduled by my plugi...

yes, sure

#

BukkitScheduler#cancelTasks(YourPlugin)

#

are you sure you didn't change anything else? show your code pls

glossy venture May 12, 2022, 4:58 PM

#

final Player player = ...;

CompletableFuture<V> future = ...;
future.whenComplete(value -> {
  Bukkit.getScheduler().runTask(() -> {
    player.sendMessage(value);
  });
});

tender shard May 12, 2022, 4:58 PM

#

?

glossy venture May 12, 2022, 4:58 PM

#

and have whatever async shit ur doing return a completable future

crude loom May 12, 2022, 4:58 PM

#

tender shard BukkitScheduler#cancelTasks(YourPlugin)

Oh that's very simple haha
Thanks !

tardy delta May 12, 2022, 4:58 PM

#

i was just going to say that you could work with futures or callbacks x)

tender shard May 12, 2022, 4:58 PM

#

crude loom Oh that's very simple haha Thanks !

np 🙂

glossy venture May 12, 2022, 4:58 PM

#

?

#

whats the issue

#

your async thread or the server thread

tardy delta May 12, 2022, 4:59 PM

#

the main thread dies?

#

then youre probably doing it sync on the main thread

glossy venture May 12, 2022, 4:59 PM

#

use a thread pool

#

and do the completable future shit i sent

tardy delta May 12, 2022, 5:00 PM

#

completablefuture uses a threadpool internally x)

glossy venture May 12, 2022, 5:01 PM

oh yeah

    });
}

    getValueAsync(/* ... */).whenComplete((val, err) -> {
        if (err != null) {
            // handle any error which occurred
            System.out.println("Error while retrieving value");
            err.printStackTrace();
            return;
        }

        // run synchronously (on the server thread)
        // required to use most of the bukkit api
        Bukkit.getScheduler().runTask(/* plugin */ this, () -> {
            // do whatever you want with the value
            player.sendMessage("Here is your value: " + val);

because you try to access "generator" when generator is still being initialized

crude loom May 12, 2022, 5:16 PM

Am I not doing the same outside the method though?

tender shard May 12, 2022, 5:16 PM

crude loom May 12, 2022, 5:16 PM

I mean, it works with 'ironGenerator', why is that?

tender shard May 12, 2022, 5:16 PM

#

no that too won't work

#

if you move the ironGenerators thing above, it will probably be angry at that part instead

crude loom May 12, 2022, 5:17 PM

#

It's only for the task inside the method, I have used the task outside the method and it works

#

For some reason it's a problem only inside a method

#

Wait nevermind I can just schedule a repeating task I don't know why am I overcomplicating things😅

quaint mantle It was just a question

want an answer ?
WELL first, highlight depens on :
the what app ur using
what theme ur using
how ur writing
and a lot.
Like if u have an error, send the error, check the line, and try finding out whats wrong

crisp steeple May 12, 2022, 5:57 PM

#

also like

#

no reason to come to a help channel just because something’s gray

#

just look it up or hover over it and it’ll probably say

#

i am pretty sure it’s just because it’s an unused field

steel swan May 12, 2022, 5:58 PM

#

crisp steeple projectilehitevent?

and check the sender? well then it would do it for every snowball that this player sends

crisp steeple May 12, 2022, 5:58 PM

#

well

#

you could add a metadata to the snowball with the player

#

then check entitydamageevent see if it’s a snowball and has the player metadata

#

i think getShooter works as well

river oracle May 12, 2022, 6:00 PM

#

idk why but getShoiter is a funny method name

steel swan May 12, 2022, 6:02 PM

crisp steeple i think getShooter works as well

when i do setMetadata, what is the "key" vallue

Ayo! How would I get a object list with the configuration api?

things:

    b: 2
  - a: 3
    b: 4

Is it getMapList?

#

Or does getConfigurationSection work somehow?

compact haven May 12, 2022, 6:06 PM

you use getList

then cast it to a list of ConfigurationSection

Hey, I was making a command for downloading files in mc to the servers directory (weird reason dont ask why)
I got it working, but basically every website gets mad at its Java useragent and all the ways i could find to fix it used different methods to what i wanted, for example openConnection and not openStream, and i didn't really understand to how to actually implement it in my code, can someone explain how I would set a useragent in this scenario, or how to edit the code so I can set a useragent for it?

else if (args.length == 2){
            String fileurl = args[0];
            String filename = args[1];
            try (BufferedInputStream in = new BufferedInputStream(new URL(fileurl).openStream());
                 FileOutputStream fileOutputStream = new FileOutputStream(filename)) {
                byte[] dataBuffer = new byte[1024];
                int bytesRead;
                while ((bytesRead = in.read(dataBuffer, 0, 1024)) != -1) {
                    fileOutputStream.write(dataBuffer, 0, bytesRead);
                }
            } catch (IOException ex) {
                plr.sendMessage(Utils.chat("&aioexception"));
                ex.printStackTrace();
            }
        }

eternal oxide May 12, 2022, 6:14 PM

#

a user agent is simply a text field in the header of your request

#

it tells the website what browser you are using

manic ice May 12, 2022, 6:15 PM

#

yes i know, how do i specify it here though?
websites see that a useragent with just "Java/1.8.0_301" as its useragent is very weird so they just respond with a 403 forbidden

eternal oxide May 12, 2022, 6:16 PM

#

manic ice yes i know, how do i specify it here though? websites see that a useragent with ...

        try {
            URL url = new URL("http://sessionserver.mojang.com/session/minecraft/profile/2643e076-2434-4994-bd91-cb076d57f941?unsigned=false");

quiet ice May 12, 2022, 7:00 PM

#

I don't see why people block stuff based on user agents, they are easily spoofable

eternal oxide May 12, 2022, 7:01 PM

#

mainly because they have to send slightly different responses depending on the agent

undone axleBOT May 12, 2022, 8:00 PM

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.

Introduction - Minecraft Plugin Development Ep. 1 (2021)

Ever wanted to know how to make Minecraft plugins for Java edition? In this new series we'll be starting with the basics and eventually diving into the advanced details of plugin development.

I've been developing plugins and running my own servers since 2013, so expect to see step-by-step tutorials with plain English explanations.

How do I use a particle without it flying away? I have a way to make shapes out of particles and am trying different particle effects. However, some particles (like flame) just fuqs off in mach 2.

#

I've seen stuff online where the particles stay where they are spawned

eternal oxide May 12, 2022, 8:38 PM

#

It depends on teh particle, but you can spawn stationary particles using teh correct method/data

tepid ore May 12, 2022, 8:39 PM

Then flame for example, how do I make it stay?

ur right

tepid ore May 12, 2022, 8:51 PM

#

Also, this does not work as you want it to e.getClickedInventory() == e.getInventory()

#

You can't do == or .equals with inventories

#

You need to either save an NBT tag in an item and read that to identify your inventory, or just compare the items one by one (would not recommend the last option)

tardy delta May 12, 2022, 8:53 PM

best thing is to compare the holder and then check items or something

either use some complicated unnecessary math

yes but you dont have to deal with offsets manually

you can actually just get the opposite block to face X

crisp steeple May 12, 2022, 9:51 PM

get players direction -> add it to their location -> use the new location as the base point for your shape

i’m not sure what happens if you try to get a block at a non-whole number so you might need to round if it doesn’t already

thjank you

#

:d

:D

earnest forum May 12, 2022, 10:07 PM

#

there's an instance of a block for every location in the world

#

the ones that don't have anything are just of type AIR

that's why you can't create a new block

but another question sorry for being anoyoying but how do i like make the shape thjoughj lmao

crisp steeple May 12, 2022, 10:10 PM

#

in your case, the shape is small enough to where you can probably just hardcode the values on

#

ex: Location pos1 = new Location(world, loc.getX() + 1, loc.getY() + 2, loc.getZ() + 3)

etc

Yeah, in my case if have a spherical border that I initiate with a command, and then use the timer scheduler thing to execute a display() and changesize() method within the border object I created with the command.

Currently the only way I have to cancel the border is by letting it shrink to a radius of 0 then it'll cancel, but is there a way I could implement a command which just cancels these timers?

ig it is spoonfeeding but that is how I learn personally. Seeing this example will help me for future interpretations aswell. Also, this code isn't made for 1.14 spigot so it doesn't function so there is still some figuring out to do.

You can use ItemStack#containsAtleast too and then remove item

hi, do you mind explaining what this does?

                    ItemStack currentItem = thePlayerInventory.getItem(slot);

creates an itemstack which is the "slot" withint he players inventory. but slot is only defined as an int so it wouldnt create anything? orrr am I dumbdumb

oh wait getmaterial DOES work for 1.14. why do I see it as depreciated

worldly ingot May 13, 2022, 2:16 AM

#

It never was deprecated as far as I'm aware.

#

Though you should be using matchMaterial() anyways

valid bay May 13, 2022, 2:22 AM

#

not sure what matchMaterial does but probably worth a try bc

                    if (currentItem.getType() == Material.DIRT && currentItem.getAmount() == mustHaveThisAmount) {

throws a hissy fit error

worldly ingot May 13, 2022, 2:27 AM

#

oh, you're doing a different thing

#

No reason for that not to work unless you're importing the wrong Material

valid bay May 13, 2022, 2:29 AM

#

I dont think the for loop is working correctly

#

bc it will only count if it is a continuous line of dirt blocks

#

player.sendMessage(String.valueOf(slot)); i used this to test

#

and yeah idk how weird

#

It only counts if the slot is occupied by something

make a class and store it into a hashmap Map<UUID, YourInventoryClass>
then everytime you open an inventory for someone then "put" the inventory instance with the player associate in to the map

or u can do a dirty trick by implement by the InventoryHolder interface then listen for it in the event

no, in the IDE you see the "original" package name

it will only change it once you actually compile your stuff

the relocation thing will always, ever, only change the package names of the shaded classes when you actually compile stuff

everything else would also make no sense tbh

I think it's because I use the libs on a modular project.

#

So I have a core module, basically it contains all of the code and another module for the cross-version support that depend on the core module , the core module has relocated the libs but not on the another module part.

Um, how can I make armor stand follow player's cursor location and it should maintain the distance. This is my attempt and the distance is not maintained when player is looking up or down.

Vector vector = data.player().getEyeLocation().getDirection().multiply(3);
Location location = data.player().getLocation().add(vector.getX(), 0, vector.getZ());

tender shard May 13, 2022, 12:37 PM

#

obviously not since you use 0 for the height

#

use vector.getY() instead of 0

summer scroll May 13, 2022, 12:39 PM

#

Since it's multiplied, I thought the Y will be multiplied too so when I look straight the armor stand will be up several blocks.

summer scroll May 13, 2022, 12:41 PM

#

tender shard use vector.getY() instead of 0

Okay that works, thanks!

Your plugins. To prevent piracy

If you intend on cancelling the task you'll have to either use the consumer, or make use of a BukkitRunnable

Bukkit.getScheduler().runTaskTimer(plugin, task -> {
    task.cancel(); // This will cancel the task
}, 0, 20);```

imagine if i have 2 ItemMetas and both of them are casted to compassmeta, i use .setlodestone on of them and then compare it with the other one using .equals, it will return false but how can i make it ignore that .setlodestone, i can check for lore, enchantments, flags, displayname, etc but i dont think its the best way

i hope you get what i mean from "ignore .setlodestone"

Call update(true, false) instead of just update()

Or it's not a banner

agile marsh May 13, 2022, 3:33 PM

#

but if you want .equals to only look at specific aspects of an item you have to override the function

#

when i say item i mean an object

eternal oxide May 13, 2022, 3:34 PM

he didn;t call update() before getting a new state, so he's still getting the old block the second time

@agile marsh just get a copy from both of them and then .setlodestone(null)

agile marsh May 13, 2022, 3:35 PM

they're just never going to be equal to eachother

civic dagger May 13, 2022, 3:35 PM

why?

agile marsh May 13, 2022, 3:35 PM

#

bc you've changed one

civic dagger May 13, 2022, 3:35 PM

#

well im changing both of them to null now

#

now they're same

agile marsh May 13, 2022, 3:36 PM

i mean changing both to null and then comparing should send a null pointer?

#

I think?

#

but yea i mean if they're both null they're obv the same

waxen plinth May 13, 2022, 3:36 PM

no the objects it self

waxen plinth May 13, 2022, 3:36 PM

You're setting the lodestone location to null

Then comparing the items

yea

This won't work if the block isn't already a banner

Need to make sure to do that first

eternal oxide May 13, 2022, 3:38 PM

#

yep I missed the setType on teh state

#

set type before

waxen plinth May 13, 2022, 3:38 PM

#

Setting type on BlockState and then casting won't work either

#

You have to set it on the block before getting the BlockState

#

An object cannot change its type

eternal oxide May 13, 2022, 3:39 PM

#

if you are working on a State it should work

waxen plinth May 13, 2022, 3:39 PM

#

BlockState s;
s.setType(Material.BANNER);
Banner b = (Banner) s;```

#

This will not work

eternal oxide May 13, 2022, 3:39 PM

#

a State is a snapshot so long as you keep that state it will work

waxen plinth May 13, 2022, 3:39 PM

#

That's not the point

#

The point is that a BlockState is an object like any other

#

It has a type, and that type cannot change

#

A type in java

#

The class it is an instance of

#

Changing the material type will not change the class of the object

#

You have to change the material of the block and THEN get and cast the BlockState to Banner

eternal oxide May 13, 2022, 3:41 PM

#

yep

tardy delta May 13, 2022, 3:41 PM

Block#setState or something?

tardy delta May 13, 2022, 3:41 PM

#

ah

waxen plinth May 13, 2022, 3:42 PM

#

And ensure that you pass (true, false) to update

#

That will prevent physics checks, allowing you to set a banner midair

Which one of these is called first?

the static block is evaluated on class load

{} is called no matter the constructor iirc

So none really

yes, static is at class load, {} is at class instantiation
