protected final synchronized sealed record A<T>(T t) {}

lavish hemlock Oct 10, 2021, 2:49 PM

#

I don't think you can synchronize a record

#

I also don't think you can make a protected class

#

I also don't think you can make a sealed record when it's also final and also records can't be inherited (also final is redundant since records are final by default)

#

so there are many things wrong with this

lets make a programming language that compiles english

at least it doesnt complain and compiles fine

lavish hemlock Oct 10, 2021, 2:51 PM

it's possible

alpine urchin Oct 10, 2021, 2:51 PM

#

And sue people for distributing our code

lavish hemlock Oct 10, 2021, 2:52 PM

#

but you probably can't use the record

#

unless you A<?> or A it

alpine urchin Oct 10, 2021, 2:52 PM

#

whenever they mention our words

lavish hemlock Oct 10, 2021, 2:52 PM

#

bc nothing can extend so A so nothing besides a raw type or wildcard can be placed there

#

so your IDE would probably warn you about doing that

yeah indeed

anyone know how I can add javadocs to the lombok constructors, builder methods and getters setters?

I know I can just write javadocs for the fields but that would require to always add the param and return things manually because IntelliJ doesnt generate them automatically for lombok annotated fields 😦

ivory sleet Oct 10, 2021, 2:58 PM

#

just dont use lombok

tender shard Oct 10, 2021, 2:58 PM

I have to support MC 1.16 too 😦

lavish hemlock Oct 10, 2021, 2:59 PM

#

record classes probably have internal JVM optimizations as they are immutable

eternal night Oct 10, 2021, 2:59 PM

#

1.16.5 latest supports java 16

lavish hemlock Oct 10, 2021, 2:59 PM

so Lombok would be the one crying

tender shard Oct 10, 2021, 2:59 PM

#

eternal night 1.16.5 latest supports java 16

but most 1.16 users are still on 1.8

#

and they won't upgrade just for one or three plugins

#

at least some of them won't

#

at least not today

#

so does anyone have a real idea instead of not using lombok? 😄

ivory sleet Oct 10, 2021, 3:01 PM

lavish hemlock Oct 10, 2021, 4:17 PM

#

perhaps if Spigot was easier to implement lol

tender shard Oct 10, 2021, 4:17 PM

maybe I'm confusing the PlayerDeathEvent bug with another hybrid thing though

Uhh, just a minor question that I should know before even starting java, but do you guys think 2 years is the needed time to learn all of the basic of java? Maybe less if you already know how coding work

tender shard Oct 10, 2021, 4:18 PM

#

quaint mantle Uhh, just a minor question that I should know before even starting java, but do ...

that highly depends. I'm sure you can learn it pretty decently in a few months when you have much time and also know other languages well. Other people however do java for years and still don't understand what they're doing

#

soooo

#

that can't be answered generally

quaint mantle Oct 10, 2021, 4:18 PM

#

Yep

#

Oh btw

#

Coding like what you love the most is better than just follow some tutorials about how you should code (clean code) right?

eternal night Oct 10, 2021, 4:21 PM

#

no

quaint mantle Oct 10, 2021, 4:21 PM

#

Depends i think

eternal night Oct 10, 2021, 4:21 PM

#

there is a line yea. Obviously on some high level you can argue about how to code and should just use your own style.

#

but "I like how my public static mutable global state variable is available everywhere" isn't too much help

quaint mantle Oct 10, 2021, 4:22 PM

I don’t even use static

That is a joke tho, but i really don’t use static

lavish hemlock Oct 10, 2021, 4:23 PM

if Java had top-level functions and namespaces

quaint mantle Oct 10, 2021, 4:23 PM

I used constructor for everything

then I wouldn't need to use static at all, really

How can I get a direction from two locations so one faces the other?

#

Lets say I have one object at 0, 0, 0 and another at 10, 10, 10. What direction does 0, 0, 0 need to face to be looking at 10, 10, 10?

#

Idk how else to explain it

tender shard Oct 10, 2021, 5:50 PM

#

stiff ember How can I get a direction from two locations so one faces the other?

you can convert both locations to a Vector

#

and then use Vector#angle(Vector) which returns the angle between both vectors in radians

#

is that what you need?

stiff ember Oct 10, 2021, 5:51 PM

#

Uh

#

yes

#

Sounds like it

#

tthanks

tender shard Oct 10, 2021, 5:52 PM

#

np

stiff ember Oct 10, 2021, 5:53 PM

#

Wait what uh

#

it says Vector.angle returns a float?

tender shard Oct 10, 2021, 5:53 PM

#

yes

stiff ember Oct 10, 2021, 5:53 PM

#

uh

tender shard Oct 10, 2021, 5:53 PM

#

I have no idea about vectors and stuff, it's just what I found by looking through the javadocs, no idea if that's anyhow related to what you need lol

stiff ember Oct 10, 2021, 5:54 PM

#

oh

#

i mean

#

it seems like it work work but I need a vector

tender shard Oct 10, 2021, 5:54 PM

#

ah I think I know what you need

stiff ember Oct 10, 2021, 5:55 PM

#

Probably something with normalize?

#

idk

tender shard Oct 10, 2021, 5:55 PM

#

subtract one vector from the other and normalize the result

stiff ember Oct 10, 2021, 5:55 PM

#

Oh

tender shard Oct 10, 2021, 5:55 PM

#

then you should have a vector pointing in the right direction

stiff ember Oct 10, 2021, 5:55 PM

#

uh wait so lets say its 10, 10, 10 and 5, 5, 5

#

would give 5, 5, 5

#

then normalize gets

#

uh

#

how does one normalize

tender shard Oct 10, 2021, 5:55 PM

#

normalize()

stiff ember Oct 10, 2021, 5:56 PM

#

oh i mean

#

outside of code

#

lol

hasty prawn Oct 10, 2021, 5:56 PM

stiff ember How can I get a direction from two locations so one faces the other?

e

tender shard Oct 10, 2021, 5:56 PM

he has two locations and wants to get the direction that you have to look from loc1 to look to loc2

stiff ember Oct 10, 2021, 5:56 PM

#

yes

hasty prawn Oct 10, 2021, 5:56 PM

#

I think you can just subtract one vector from the other and it'll give you a vector that starts at one and points to the other

tender shard Oct 10, 2021, 5:56 PM

#

yep

#

and then normalize it

hasty prawn Oct 10, 2021, 5:56 PM

#

^

#

Well depending on what you wanna do with it I guess

tender shard Oct 10, 2021, 5:57 PM

#

yeah true

hasty prawn Oct 10, 2021, 5:57 PM

#

If you're setting Velocity, yeah, normalize it KEKW

stiff ember Oct 10, 2021, 5:57 PM

#

ok ill try it

tender shard Oct 10, 2021, 5:57 PM

#

to get pitch / yaw you probably have to do this ugly sin/cos things on the nomalized vector I assume? 😄

stiff ember Oct 10, 2021, 5:58 PM

#

yeah im trying to make a turret

#

uh

#

oh

#

wait you cant cast location to vector?

Location.toVector

https://bukkit.org/threads/lookat-and-move-functions.26768/

LookAt and Move functions | Bukkit Forums

I already wrote these functions for my own Java game before, but it could be useful to lots of other people

lookAt
What it does is make a Location...

#

this is probably what you're looking for?

stiff ember Oct 10, 2021, 6:00 PM

#

Oh

#

I need all of that?

tender shard Oct 10, 2021, 6:01 PM

#

the first code

#

you provide two locations

#

your current location

#

the location you want to look at

#

then it returns location number 1 with adjusted pitch/yaw

#

so that you are still standing at loc1 but you are looking at exactly loc2

#

isn't that what you need?

stiff ember Oct 10, 2021, 6:02 PM

#

uhhhh

#

I think I need a vector

tender shard Oct 10, 2021, 6:02 PM

#

what exactly are you trying to achieve?

stiff ember Oct 10, 2021, 6:02 PM

#

trying to make a turret that shoots at nearby players with arrows

#

I already got nearby players

#

just need to shoot them

tender shard Oct 10, 2021, 6:03 PM

#

is your turrent an entity?

#

or what exactly is it?

stiff ember Oct 10, 2021, 6:03 PM

#

block

#

its end rod

tender shard Oct 10, 2021, 6:03 PM

#

so you only need a vector where it should at

#

shoot at*

stiff ember Oct 10, 2021, 6:03 PM

#

uh

#

Im using the

#

World.spawnArrow(Location, Vector (rotation), speed, somethingelse)

tender shard Oct 10, 2021, 6:04 PM

#

Location turretLocation = ...;
Location whereToShootAt = ...;

Vector direction = turretLocation.toVector().substract(whereToShootAt.toVector()).normalize();

stiff ember Oct 10, 2021, 6:05 PM

#

Its that short?

tender shard Oct 10, 2021, 6:05 PM

#

you can then then use turretLocation as Location in the spawnArrorMethod, and direction as your Vector (rotation) thing

#

(I THINK)

#

just try it

#

if it shoots in the opposite direction, you have to switch the turretLocation and whereToShootAt location of course in the vector calculations

stiff ember Oct 10, 2021, 6:06 PM

#

subtract or substract?

#

Apparently both exist

#

in the context

tender shard Oct 10, 2021, 6:06 PM

#

hugh? both exist?

#

only subtract exist, I just made a typo

stiff ember Oct 10, 2021, 6:06 PM

#

on an object

#

oh

tender shard Oct 10, 2021, 6:06 PM

#

I just typed it into discord

stiff ember Oct 10, 2021, 6:06 PM

#

Object.substract works

tender shard Oct 10, 2021, 6:07 PM

#

stiff ember Object.substract works

?

stiff ember Oct 10, 2021, 6:07 PM

#

Well

#

it was happy with .substract once I casted the vector to an object

tender shard Oct 10, 2021, 6:09 PM

#

stop blindly casting everything

#

also

#

everything in java is an object

stiff ember Oct 10, 2021, 6:09 PM

#

yeah ik

tender shard Oct 10, 2021, 6:09 PM

#

and Object also doesnt have any "substract" method

stiff ember Oct 10, 2021, 6:09 PM

#

it was a suggested thing

#

nvm

#

i was wrong

#

it was something else

stiff ember Oct 10, 2021, 6:14 PM

#

lol its shooting backwards

#

and from the corner of the block

#

just multiply by -1 i guess and subtract 0.5 from x and y

#

or is it add 0.5?

tender shard Oct 10, 2021, 6:16 PM

#

tender shard if it shoots in the opposite direction, you have to switch the turretLocation an...

multiply by -1 or as said here:

stiff ember Oct 10, 2021, 6:16 PM

#

oh

#

didnt see that

tender shard Oct 10, 2021, 6:16 PM

#

multiplying by -1 should work fine

stiff ember Oct 10, 2021, 6:21 PM

#

I just switched them

#

looks cleaner I think

tender shard Oct 10, 2021, 6:26 PM

is it working?

ivory sleet Oct 10, 2021, 7:41 PM

#

The interact event maybe?

tender shard Oct 10, 2021, 7:41 PM

#

Currently I'm simply calling PlayerInteractEvent and check if it gets cancelled, buuut that leads to WorldGuard messages when they are not allowed, and sometimes opens GUIs for some plugins

tender shard Oct 10, 2021, 7:41 PM

#

ivory sleet The interact event maybe?

yeah but that has some side effects for some plugins :/

ivory sleet Oct 10, 2021, 7:41 PM

#

What priority?

#

Might wanna try and lower/higher one

tender shard Oct 10, 2021, 7:42 PM

well I'm just calling the event and then check if it was cancelled

I'm not listening to it

ivory sleet Oct 10, 2021, 7:42 PM

Wait wat

#

Oh

tender shard Oct 10, 2021, 7:42 PM

#

yeah imagine I have to know whether a player is allowed to open a chest at x100 y64 z100

#

so I call a PlayerInteractEvent with "player XY right clicked the block at x100 y64 z100"

#

and if that get's cancelled, i know a player isn't allowed to open that chest

ivory sleet Oct 10, 2021, 7:43 PM

#

Ah

tender shard Oct 10, 2021, 7:43 PM

#

I haven't found a better way so far

ivory sleet Oct 10, 2021, 7:43 PM

Most plugins should have some sort of api for you to hook into

well I cannot hook into 100 APIs 😄

ivory sleet Oct 10, 2021, 7:44 PM

for my ChestSort plugin, players can sort a chest by leftclicking it

stiff ember Oct 10, 2021, 7:44 PM

#

What about nms?

tender shard Oct 10, 2021, 7:44 PM

#

the alternative would be the player to open the chest (so they would actually do a playerinteractevent anyway) and then sort it with the inventory open

stiff ember Oct 10, 2021, 7:44 PM

#

packets

tender shard Oct 10, 2021, 7:45 PM

you mean regardless of whether it was placed left/right/up/down of a block?

stiff ember Oct 10, 2021, 7:52 PM

#

yeah

#

Is there an easy way to do it?

#

Without a bunch of ifs

tender shard Oct 10, 2021, 7:53 PM

#

Block has a method getBoundingBox

#

but you'd still have to do some calculations based on the rotation of the rod etc

stiff ember Oct 10, 2021, 7:54 PM

#

Well if I know the rotation I can just add or subtract one to the right axis

#

e

#

Ill have to do that i guess

tender shard Oct 10, 2021, 7:54 PM

#

End rod's blockdata implements Directional

#

so cast the Block#getBlockData to Directional and you can get the BlockFace / "rotation"

#

import org.bukkit.block.data.Directional;
Block block = e.getBlockPlaced();
Directional blockData = (Directional) block.getBlockData();
blockData.getFacing()

unkempt peak Oct 10, 2021, 8:05 PM

Bukkit.getOfflinePlayer?

clear blade Oct 10, 2021, 8:05 PM

#

seriously lmao is that it

olive valve Oct 10, 2021, 8:05 PM

#

it output 2

hasty jackal Oct 10, 2021, 8:05 PM

#

neither length nor printing out the array will help

#

you need to print out the actual object at the index

#

which will be null

#

otherwise it wouldn't error

unkempt peak Oct 10, 2021, 8:05 PM

#

clear blade seriously lmao is that it

Yes but also don't use names. Use UUIDs

clear blade Oct 10, 2021, 8:06 PM

#

see that's the thing- i need to use usernames here because it's a hassle for players to grab their uuid

#

is there some API i can poll?

unkempt peak Oct 10, 2021, 8:06 PM

#

Why can't you get the uuid?

clear blade Oct 10, 2021, 8:07 PM

#

because this is a command that's being run from discord 😛

unkempt peak Oct 10, 2021, 8:08 PM

#

What does the bot command do in discord?

clear blade Oct 10, 2021, 8:09 PM

#

whitelists a user if they have a given role

#

then links their discord ID to their minecraft UUID

olive valve Oct 10, 2021, 8:09 PM

#

hasty jackal otherwise it wouldn't error

it outputs the item i put in slot1 only when i put in slot1 if i put it in slot2 it only outputs the NullPointerException

unkempt peak Oct 10, 2021, 8:09 PM

#

Ah ok

hasty jackal Oct 10, 2021, 8:10 PM

#

which makes complete sense

#

because if there's no item in the first slot it will be null

#

and you're calling a method on it

unkempt peak Oct 10, 2021, 8:10 PM

#

Just do a null check @olive valve

olive valve Oct 10, 2021, 8:11 PM

#

unkempt peak Just do a null check <@719227090993414196>

oh ive tried that

it doesnt work

Show code

olive valve Oct 10, 2021, 8:13 PM

#

if(slot1 == null) return;, if (slot2 == null) return;

unkempt peak Oct 10, 2021, 8:13 PM

#

It's throwing an npe because slot1 is null. You need to check if slot1 is null before doing anything with it

#

What line is the npe being thrown at?

unkempt peak Oct 10, 2021, 8:19 PM

ok then check if slot2 is null first

#

if you don't want do anything when slot 2 is empty return if it's null

clear blade Oct 10, 2021, 8:20 PM

#

eternal night just make sure to throw those calls onto another thread

https://www.twilio.com/blog/5-ways-to-make-http-requests-in-java it seems there are ways to make asynchronous HTTP calls that won't block the main thread- as a mostly javascript developer, async means it doesn't block the main thread and allows other things to execute. is this not the case for java? do i still need to run the call on another thread?

olive valve Oct 10, 2021, 8:21 PM

#

unkempt peak ok then check if slot2 is null first

it changed the NullPointerException to line ItemStack result = new ItemStack(slot1.getType());

unkempt peak Oct 10, 2021, 8:21 PM

#

then do the same for slot1

#

you always need to null check stuff like that before using it

hasty prawn Oct 10, 2021, 8:22 PM

#

noble knot Hi how do i add content to a book? When I try i get this

Did you give it an author?

#

Books require some specific type of data, else they do that

#

Author is one of them, I think there's another but not 100% sure.

olive valve Oct 10, 2021, 8:23 PM

unkempt peak then do the same for slot1

it worked!!

ohhh

i was doing e.getInventory().getView()

that explains it

I'm making a thing where you right click a block and it opens a gui, and then you click different items to change that block. How can I get the block they right clicked in the inventory click event?

eternal night Oct 10, 2021, 8:45 PM

store it in some form of map ?

you could also use a custom InventoryHolder

I tried to make the command directly on the sql db and it does return a table with the values I want

#

So, I don't understand why 🥲

tiny wolf Hold up, and how is my gui var ever being changed! its final

wym?

tiny wolf Oct 10, 2021, 9:29 PM

#

so what is intended is for it to get the items from a config once

#

but for some reason every time I open the gui it decides to add another item to it

young knoll Oct 10, 2021, 9:30 PM

#

The inventory may be final

#

But the contents aren't

#

Similar to how you can add to a final ArrayList

tiny wolf Oct 10, 2021, 9:31 PM

#

isnt that the whole point of final..

#

that it cant be changed

hasty jackal Oct 10, 2021, 9:31 PM

#

no, the point is that you cannot re-assign a variable

young knoll Oct 10, 2021, 9:32 PM

#

^

tiny wolf Oct 10, 2021, 9:32 PM

#

anyways, it anyways is never setting that main variable as far as im aware to add items

ivory sleet Oct 10, 2021, 9:32 PM

#

final is mostly a compile time feature to write code defensively

#

yeah but that shit does it on runtime

#

and it actually overrides final, yes ikr hacky

young knoll Oct 10, 2021, 9:33 PM

#

But not static final

tiny wolf Oct 10, 2021, 9:33 PM

#

I only set the local variable to the inv, never set the items in the main gui

ivory sleet Oct 10, 2021, 9:33 PM

#

I believe only true constants cannot be changed with reflection due to inlining

young knoll Oct 10, 2021, 9:34 PM

#

Well you can't change static final fields anymore with just reflection

ivory sleet Oct 10, 2021, 9:34 PM

pretty sure you can?

young knoll Oct 10, 2021, 9:34 PM

Nah you need Unsafe

ivory sleet Oct 10, 2021, 9:34 PM

if its just static final MyCustomObject o = new MyCustomObject(); or smtng

young knoll Oct 10, 2021, 9:34 PM

#

Private static final to be exact

#

Try it

tiny wolf Oct 10, 2021, 9:35 PM

#

ok

young knoll Oct 10, 2021, 9:35 PM

#

In java 16

ivory sleet Oct 10, 2021, 9:35 PM

#

you'd ofc need to set the field accessible but else than that afaik only constants are what dont work

#

(true constants)

young knoll Oct 10, 2021, 9:35 PM

#

The problem is you can't do this anymore

 Field modifiersField = Field.class.getDeclaredField("modifiers");
      modifiersField.setAccessible(true);
      modifiersField.setInt(field, field.getModifiers() & ~Modifier.FINAL);

hushed spindle Oct 10, 2021, 9:36 PM

#

hey guys, i was wondering if there's any particular reason why you can't edit the drops of a blockbreakevent directly. the only way that you can currently edit item drops is if you set the event to not drop items and to then drop them manually, but i feel this to be kind of hacky and makes it harder to make your plugins compatible with others in certain situations. i dont need to know how to do it, i just wonder about the reason why there isn't a BlockBreakEvent#setDrops(collection of item) method to make it more straightforward

young knoll Oct 10, 2021, 9:36 PM

No idea why it's immutable

Spigot moment I guess

oh yeah but just
AccssibleObject::setAccessible should be enough on the actual field

young knoll Oct 10, 2021, 9:37 PM

#

Newer java blocks it afaik

eternal night Oct 10, 2021, 9:37 PM

#

because you are reflecting into jdk internals

#

which are now locked in their module

young knoll Oct 10, 2021, 9:37 PM

#

Because Field is a protected class

eternal night Oct 10, 2021, 9:37 PM

and no longer exposed

same reason you can no longer call URLClassLoader#addUrl anymore

quaint mantle Oct 10, 2021, 10:12 PM

#

I used constructor, but someone said that a constructor only need 3 classes, if it more than only 3 class then use something else, what it call, uhhh builder pattern or something

ivory sleet Oct 10, 2021, 10:17 PM

#

no no no thats definitely not what you want to follow

#

Sure it might be convenient

#

but if you have an intermediate component which just requires other intermediate components it'd be perfectly fine just doing smtng like

Configuration config = new JsonConfiguration(
  new JsonLoader(),
  new ConfigurationSerializer(serializerContext),
  this.plugin,
  path -> Files.newBufferedReader(path),
  path -> Files.newBufferedWriter(path)
);

#

here all the components passed are significantly distinctive

#

so we dont need a builder really

#

even tho it surpasses 3 arguments

#

okay maybe not the last two

#

but yeah you get the point

in a uuid

opal juniper Oct 10, 2021, 10:31 PM

and probably use location instead of block

opal juniper Oct 10, 2021, 10:32 PM

stiff ember Oct 10, 2021, 10:33 PM

would that save to file?

opal juniper Oct 10, 2021, 10:33 PM

uuids can go to string easily

Does spigot already handle serilization for UUIDs?

young knoll Oct 10, 2021, 10:34 PM

Either way you have toString and UUID.fromString

opal juniper Oct 10, 2021, 10:34 PM

uuid is just a java thing tho right?

young knoll Oct 10, 2021, 10:34 PM

Yes

So are a lot of things you can serialize

quaint mantle Oct 10, 2021, 10:34 PM

UUIDs normally give the string representation

they serialize perfectly

Ik it's a dumb question, but what is the best way to innit a list? I am doing it like this rn:

    List<String> bannedWords = new ArrayList<>(){{
        add("word 1");
        add("word 2");
        add("word 3");
        add("word 4");
        add("word 5");
    }};

sullen marlin Oct 10, 2021, 11:22 PM

Arrays.asList("word 1", "word 2" ....)

if you're looking for banned words consider using a set though

where does the path start?

wide flicker Oct 10, 2021, 11:46 PM

for config.set("path", "value");, the path is inside the config file. Like if you wanted to set name to whatever value, you'd put name for the path.

If you're talking about new File(getDataFolder() + File.separator + "your_config.yml");, that's gonna be in your plugin's folder

Just a minor question, how would this (default reloadConfig by spigot (or paper idk if they changed those))

    @Override
    public void reloadConfig() {
        newConfig = YamlConfiguration.loadConfiguration(configFile);

        final InputStream defConfigStream = getResource("config.yml");
        if (defConfigStream == null) {
            return;
        }

        newConfig.setDefaults(YamlConfiguration.loadConfiguration(new InputStreamReader(defConfigStream, Charsets.UTF_8)));
    }```
different than this
```java
    public void reloadConfig() {
        customConfig = new YamlConfiguration();
        try {
            customConfig.load(customConfigFile);
        } catch (IOException | InvalidConfigurationException e) {
            e.printStackTrace();
        }
    }```
I read through the first one, but still havent found out the different between 2 of them

Using the Annotation Command Framework, is it possible to add command aliases loaded from the config file? Or do the aliases HAVE to be defined using an annotation?

tender shard Using the Annotation Command Framework, is it possible to add command aliases lo...

I saw that in the example on GitHub (the EmpireRoleManagementComand), the CommandAlias annotation has "%empirecommand" as value, but I have no idea on how to define this %empirecommand in ACF :/

got another ACF question:

    @Default
    public static void onDefault(CommandSender sender, @Optional Player player) {

How can I make ACF print something like "Player asdasd not found" when an argument is given but the player isn't online? I want to the command to only work when people enter no player name, or a valid one, but not when they enter an invalid player name
