Can you explain more about the end goal

I smell xy problem

lyric gyro Mar 25, 2022, 6:34 PM

the root component of each line can have a valid run_command action, and the server checks for that when you right click a sign

forest jay Mar 25, 2022, 6:35 PM

icy shadow Can you explain more about the end goal

I have a texture that shows on the sign. and the sign has a invisible texture, so only the image shows. But when the player hovers over the image they see the sign hitbox

Does this AtomicBoolean look good for you?

public boolean unlinkContainer(@NotNull Container container) {
    Location containerLocation = container.getLocation();
    AtomicBoolean isAnyRemoved = new AtomicBoolean(false);

    _hopperRepository
        .findByContainerLocation(containerLocation)
        .forEach(hopper ->{
            boolean isRemoved = hopper.removeContainer(containerLocation);
            isAnyRemoved.set(isAnyRemoved.get() | isRemoved);
        });

    return isAnyRemoved.get();
}

IntelliJ recommended this over using a local variable which obviously did not compile. Does this do what I want?

lyric gyro Mar 26, 2022, 1:54 AM

because it builds on top of it?

robust flower Mar 26, 2022, 1:54 AM

#

I think it is because Spigot depends on CraftBukkit which depends on Bukkit

#

Bukkit is the API (lots of interfaces), CraftBukkit is the implemention of these interfaces (for the most part), and Spigot just adds some things to it

#

Though I have no idea why does CraftBukkit jar doesn't come with Bukkit shaded in it

lyric gyro Mar 26, 2022, 1:56 AM

#

presumably for a clean dependency tree

#

like the actual project depends on the other actual project

robust flower Mar 26, 2022, 1:57 AM

#

hmmm, but the buildtools actually built the final jar, correct? Shouldn't craftbukkit shade bukkit for it to work?

hoary scarab Mar 26, 2022, 1:57 AM

#

Bukkit is the api so doesn't it shade craftbukkit?

lyric gyro Mar 26, 2022, 1:58 AM

they can coexist as separate jar files and so long as both are in the runtime classpath they will work fine

I am bad at vector math
I am trying to create a function that will duplicate custom regions. I get the cardinal direction the player is facing and taking an input I multiply the direction vector by the distance (in this case 20) and then apply that vector to the region points.

But it seems that I'm getting the wrong number after the first region is moved.

First teleport is an original region, the second is the first cloned and the third is meant to be a clone of the first but it has a Z of 8014 instead of 34
(20 blocks away)

Clone Command: https://paste.helpch.at/awicosiqoz.java
Region: https://paste.helpch.at/oralezuhap.java

edit: The clone of the second teleport would be at origin 16.5, 65, 14.5

So there is a 2 tall sugarcane, I break the bottom one: bottom will fire BlockBreakEvent and BlockDropItemEvent, but what will fire for others?
I found that BlockDestroyEvent is actually fired, but there are no list of items to be dropped, but I want to manipulate the items to be dropped. How can I do that?

Well you could just check if above blocks match the block you're breaking and remove them manually.

Is there a fast way to apply new versions of a plugin while developing? currently I do:
gradle clean build, then copy jar file manually to plugins folder**, stop server, start server again, wait until reloads.**
the bolded part takes a lot, can I help on that?

dense drift Mar 26, 2022, 5:27 PM

Theres a thing called hotswap, but for some things you still have to restart the server

#

I usually click on the restart button from IJ and it waits for the server to stop and then start it again

https://github.com/ArtFect/BlockHighlight

This person created a way to highlight blocks for players using debug/game_test_add_marker without making any modifications to the client. My understanding of coding plugins is to basic to able able to try and understand how the things work?

#

I simply want to use this idea, and make a command that highlights a blocks.
For example

/highlight x y z

#

.

Ive been starring at this plugin for hours and cant seem to understand how on earth this person was able to do this

dusky harness Mar 26, 2022, 5:53 PM

tidal canopy . Ive been starring at this plugin for hours and cant seem to understand how on...

#

this is the actual highlight code

#

https://github.com/ArtFect/BlockHighlight/blob/master/src/main/java/ru/fiw/blockhighlight/PacketUtil.java here are the PacketUtil methods

#

and highlight.getColor() is Color.RED.getRGB() for ex

#

this also uses ProtocolLib

#

what it does is it sends a Custom Payload packet with the channel debug/game_test_add_marker, and it serializes the marker (aka the block highlights) into bytes (ByteBuf) and sends it to the client

yes, thats part of the info that gets sent to the client

instead of 3 integers, it just sends 1 long

it seems to be under MIT license

well

are you going to use ProtocolLib?

For now im not planning on it

dusky harness Mar 26, 2022, 6:07 PM

I mean sure, although a disadvantage with having some sort of general observer implementation is that in the long term it can become a bit hard to figure out what units depend on which event. (Of course you could ensure a single method registers possible observers (which is easy to do as long as the code base hasn’t grown colossally large))

org.bukkit.entity.Player#sendTitle

void sendTitle(@Nullable String title, @Nullable String subtitle, int fadeIn, int stay, int fadeOut)```

Description:

Sends a title and a subtitle message to the player. If either of these values are null, they will not be sent and the display will remain unchanged. If they are empty strings, the display will be updated as such. If the strings contain a new line, only the first line will be sent. All timings values may take a value of -1 to indicate that they will use the last value sent (or the defaults if no title has been displayed).

Parameters:

title - Title text
subtitle - Subtitle text
fadeIn - time in ticks for titles to fade in. Defaults to 10.
stay - time in ticks for titles to stay. Defaults to 70.
fadeOut - time in ticks for titles to fade out. Defaults to 20.

Make your time variable an int, and use getInt for the config, then just use the valueOf in the method

quasi kraken It doesn't show up when I do /plugins

Can you provide your console log for the error via the paste slash command?

quasi kraken Mar 29, 2022, 5:49 AM

#

Wdym

#

I don't exactly understand.

winged pebble Mar 29, 2022, 5:49 AM

#

If it doesn't show up in /plugins then it's either not in the plugins folder or there is an error when it tried to load

quasi kraken Mar 29, 2022, 5:50 AM

#

So my custom join/leave and staffchat plugin are loading, but the custom items are not

winged pebble Mar 29, 2022, 5:51 AM

#

The console will show the error that caused it to not load

quasi kraken Mar 29, 2022, 5:52 AM

#

No error at all

winged pebble Mar 29, 2022, 5:52 AM

#

Is it in the plugins folder?

quasi kraken Mar 29, 2022, 5:52 AM

#

Yeah

winged pebble Mar 29, 2022, 5:53 AM

#

Find in the console where it tries to load in the plugin and find the error there

#

ctrl + f in the latest.log is a quick and easy way to find it too

quasi kraken It should work.

I'm telling you, you must have a error, and if not you are writing or compiling incorrectly.

pearl topaz Mar 29, 2022, 5:52 PM

#

but i can't work out how to do this with generics

#

it's just public void setValue(ArrayList<T> value) {}

#

i've tried adding

    public Class<T> getType() {
        return this.type;
    }
```to the `ArrayMonitor` class

#

so you set the type when you make it

lyric gyro Mar 29, 2022, 5:53 PM

#

generics ugh

pearl topaz Mar 29, 2022, 5:53 PM

#

but i can't seem to substitute that in for TYPE here new ArrayList<TYPE>(List.of(value.split(","))))

icy shadow Mar 29, 2022, 5:54 PM

#

what in the hell

#

Um

#

can you show the code for ArrayMonitor

#

Because I have no idea what this is supposed to do

pearl topaz Mar 29, 2022, 5:56 PM

#

arraymonitor basically just sets a redis value every time there's a set operation

#

so i'm overriding ArrayList<T>

icy shadow Mar 29, 2022, 5:56 PM

#

😵‍💫

#

please show the full class

pearl topaz Mar 29, 2022, 5:57 PM

#

there's nothing else relevant

icy shadow Mar 29, 2022, 5:57 PM

#

kinda is

#

Are you overriding every single arraylist method?

pearl topaz Mar 29, 2022, 5:58 PM

#

no, i actually only override public T set(int index, T element) {} and then i have my ownsetValue method i showed above

icy shadow Mar 29, 2022, 5:59 PM

#

Ok

#

Well first off consider implementing List rather than forcing it to a specific implementation

#

I still don't really get what the problem is though

#

If you have an ArrayMonitor<Integer> then T = Integer and so setValues must take an ArrayList<T>

pearl topaz Mar 29, 2022, 6:00 PM

#

yes but how do i get java to know it's an ArrayMonitor<Integer>

icy shadow Mar 29, 2022, 6:01 PM

#

where?

#

it'll know as soon as it's created

#

ArrayMonitor<Integer> blah = new ArrayMonitor<Integer>();

pearl topaz Mar 29, 2022, 6:02 PM

#

as i said above

#

i'm retrieving it from a hashmap

#

of type HashMap<String, Monitor>

#

where Monitor is an interface that ArrayMonitor implements

icy shadow Mar 29, 2022, 6:03 PM

#

Then there's no way of knowing at compile time

#

Unless you as the developer know from the context

pearl topaz Mar 29, 2022, 6:04 PM

#

again

#

as ive said i did

public Class<T> getType() {
        return this.type;
    }

#

in the arraymonitor class

icy shadow Mar 29, 2022, 6:04 PM

#

Yeah that doesn't change anything

#

Not at build time anyway

#

Generics only exist for the compiler

#

At runtime, they don't exist

#

And so <arrayMonitorType> won't work

pearl topaz Mar 29, 2022, 6:06 PM

#

well then i need a switch statement

icy shadow Mar 29, 2022, 6:06 PM

#

something like

#

oh dear lord

#

You're gonna do that for every single class?

pearl topaz Mar 29, 2022, 6:12 PM

lyric gyro Mar 29, 2022, 6:12 PM

#

scala 😩

sterile hinge Mar 29, 2022, 6:12 PM

#

but the arraylist will neither contain booleans nor bytes?

icy shadow Mar 29, 2022, 6:12 PM

#

just keep it unchecked, there's really no better way

pearl topaz Mar 29, 2022, 6:12 PM

#

i mean yeah this gives me many errors

pearl topaz Mar 29, 2022, 6:12 PM

#

icy shadow just keep it unchecked, there's really no better way

wdym

sterile hinge Mar 29, 2022, 6:13 PM

#

you cannot cast strings in a list to any other type randomly

icy shadow Mar 29, 2022, 6:13 PM

#

pearl topaz i mean yeah this gives me many errors

Mainly because .split() is returning a String[] and you're expecting that to magically turn into any other type

#

ArrayMonitor or ArrayMonitor<?>

#

Unbound not unchecked*

#

If you're looking for a way to arbitrarily parse Strings into different types that's a whole different issue without a great solution

pearl topaz Mar 29, 2022, 6:15 PM

#

so it's not easy to reverse this.value.toString() for private ArrayList<T> value;?

#

even if i know the T

icy shadow Mar 29, 2022, 6:15 PM

#

not trivial, no

pearl topaz Mar 29, 2022, 6:15 PM

#

well i need to do that

icy shadow Mar 29, 2022, 6:16 PM

#

I mean if you know all the types then sure, write the parsing logic manually

#

Boolean.valueOf, Integer.parseInt, etc

#

But for any arbitrary type this is pretty much impossible

sterile hinge Mar 29, 2022, 6:17 PM

#

toString might not be enough then either

icy shadow Mar 29, 2022, 6:18 PM

#

toString is not designed for serialisation so yeah

#

literally anything else would be better

pearl topaz Mar 29, 2022, 6:18 PM

#

what would you recommend for serialising more complex types like this?

#

the reason it's a pain is im forced to use redis

#

which stores strings

icy shadow Mar 29, 2022, 6:19 PM

#

JSON if you want user friendly formatting, otherwise Java persistence API might actually be the easiest option

#

it's not human readable but it just works

#

in most cases

pearl topaz Mar 29, 2022, 6:22 PM

#

can't say anything i've read so far about JPA makes any sense

icy shadow Mar 29, 2022, 6:22 PM

#

oh wait sorry not jpa

#

Java serialization api

#

Got them confused

lyric gyro Mar 29, 2022, 6:24 PM

#

java.io.Serializable 😵‍💫

icy shadow Mar 29, 2022, 6:25 PM

#

Problem?

pearl topaz Mar 29, 2022, 6:25 PM

#

still can't really find any examples that make sense to me, for doing it easily with multiple types like ArrayList<Boolean>, Char, ArrayList<Float> etc

lyric gyro Mar 29, 2022, 6:25 PM

#

If anything take an ObjectMapper type or w/e and let the client provide a (de)serialization function

icy shadow Mar 29, 2022, 6:26 PM

#

look I'm pretty much having to guess the context

#

But afaik the types will always be known

icy shadow Mar 29, 2022, 6:26 PM

#

pearl topaz still can't really find any examples that make sense to me, for doing it easily ...

ObjectInput/Output stream can input or output an arbitrary Serializable object, which all the JDK types like Boolean and Char are

pearl topaz Mar 29, 2022, 6:27 PM

#

icy shadow ObjectInput/Output stream can input or output an arbitrary Serializable object, ...

yeah im seeing that in examples like https://www.geeksforgeeks.org/serialization-in-java/ but it's really not making any sense in a practical way

icy shadow Mar 29, 2022, 6:28 PM

#

ObjectInputStream whatever = whatever
Serializable value = whatever.readObject()
ArrayMonitor<?> monitor = map.get(idk)
List<?> valueList = (List<?>) value;
monitor.setValues(valueList);

#

Roughly what needs doing

#

It's not pretty but should work

#

Or the ObjectMapper thing or JSON, the end result is the same

lyric gyro Mar 29, 2022, 6:30 PM

#

Just to make it clear: I don't think there is a "safe" way to know the (unknown) types at compile-time, so you're going to have to cast unsafely eventually

icy shadow Mar 29, 2022, 6:31 PM

#

Yeah I'm 99% sure there's no "proper" way of doing it

pearl topaz Mar 29, 2022, 6:31 PM

#

lyric gyro Just to make it clear: I don't think there is a "safe" way to know the (unknown)...

what's wrong with

        return this.type;
    }```

icy shadow Mar 29, 2022, 6:31 PM

#

that does not help at compile-time

lyric gyro Mar 29, 2022, 6:31 PM

#

^

icy shadow Mar 29, 2022, 6:32 PM

#

Storing the class is useful if you need to know the type at runtime, which you may need to

#

But it won't stop the fact that you need to do unsafe casts sooner or later

they may be different types, that can't be known at compile-time, that's why you ought to "unsafely" cast eventually

pearl topaz Mar 29, 2022, 6:47 PM

icy shadow public method takes List<T>, internal method takes List<?>

right i see

i don't really get the advantage of passing it to a private method

icy shadow Mar 29, 2022, 6:47 PM

#

Aside from the extremely unhelpful error message, looks fine

icy shadow Mar 29, 2022, 6:48 PM

#

pearl topaz i don't really get the advantage of passing it to a private method

If your public method takes <?> then you (or someone else) could accidentally pass a List<String> when you have an ArrayMonitor<Integer>

#

It's not a necessity but the private public thing means you only bypass the safety when it's necessary, making it harder for accidental bugs

pearl topaz Mar 29, 2022, 6:49 PM

#

ohh i see

#

that makes sense now

#

wait but then if i do something like

public void setValue(ArrayList<T> value) {
    setValueInner(value);
}

then i still get the error

#

icy shadow Mar 29, 2022, 6:51 PM

#

that's the safe method

#

For the deserialization you use the unsafe method

#

i.e setValueInner

pearl topaz Mar 29, 2022, 6:52 PM

#

oh so in general i use setValue

#

just here i use the unsafe one

there is one bad way which sorta abuses java's type erasure and that's to make the map Monitor<Object> and just cast everything to Monitor<Object> and suppress IJ's warnings

but

dusky harness Mar 29, 2022, 10:36 PM

dusky harness https://pastes.dev/Kf5XORofDe https://pastes.dev/QeNFar618E

but i'd prefer this, as it should only take about a minute for each

#

or less

#

why do u have 20 tho

#

🤔

pearl topaz Mar 29, 2022, 10:37 PM

#

that wouldn't fix 'setValue(Object)' in 'monitors.BooleanMonitor' clashes with 'setValue(T)' in 'org.apache.commons.lang3.mutable.Mutable'; both methods have same erasure, yet neither overrides the other anyways

dusky harness Mar 29, 2022, 10:37 PM

#

pearl topaz that wouldn't fix `'setValue(Object)' in 'monitors.BooleanMonitor' clashes with ...

which one?

#

since the one i linked i tested

pearl topaz Mar 29, 2022, 10:37 PM

#

Monitor<Object>

dusky harness Mar 29, 2022, 10:37 PM

#

oh 🤔

#

no i mean

#

in the map

#

and only in the map

#

so you'd keep this

pearl topaz Mar 29, 2022, 10:41 PM

#

i'm trying to actually test any of this

#

but it keeps running classes im not using

#

so i have a package monitors with the interface and all the classes

#

and on all the classes i've written @Ignore except ArrayMonitor and Monitor

#

and it just gives me errors from the ByteMonitor class???

#

it's running code not even inside that package

#

wtffff

IDE? and provide what you are running

pearl topaz Mar 29, 2022, 10:48 PM

#

pearl topaz and on all the classes i've written `@Ignore` except `ArrayMonitor` and `Monitor...

realised this isnt what you are actually meant to do to ignore classes, but dont see why it's running everything

pearl topaz Mar 29, 2022, 10:48 PM

#

neon wren IDE? and provide what you are running

intellij, and that code is the test

#

it's doing :test --tests "MiscTests"

neon wren Mar 29, 2022, 10:48 PM

#

So did you tell it to run the tests or run the projects.

pearl topaz Mar 29, 2022, 10:48 PM

it's running misctests

neon wren Mar 29, 2022, 10:48 PM

#

What library are you using for the Tests.

pearl topaz Mar 29, 2022, 10:49 PM

#

Junit

neon wren Mar 29, 2022, 10:50 PM

#

Next to the line number click to the right and it should offer a message to run tests that way

#

Give me a moment, as I am on my phone but that should work to run individual tests for methods

idk why it's running the task compileJava

#

which presumable tries to compile everything

neon wren Mar 29, 2022, 10:52 PM

Because the project name is MiscTests? I’d presume it is running the project which is everything.

pearl topaz Mar 29, 2022, 10:52 PM

just copy & paste it to a different project

even if i literally make

yes

thats what tests do

it builds your project and tests it

Alright, anyways if you really wanna avoid a recompile of your entire system, you might wanna divide your system into smaller subprojects/modules

pearl topaz Mar 29, 2022, 11:03 PM

i think you're misunderstanding what i'm saying or dont know how to use junit (i dont either)

orrrr this

pearl topaz Mar 29, 2022, 11:03 PM

dusky harness orrrr this

bro im not doing some dumb workaround for a standard test

#

no offense it's just

#

i want to do it the proper way

#

going forward

dusky harness Mar 29, 2022, 11:04 PM

#

proper way of using junit = testing production code

#

or

graceful hedge Mar 29, 2022, 11:04 PM

#

I mean you literally shouldn’t avoid compileJava

#

It’s crucially necessary for you

pearl topaz Mar 29, 2022, 11:04 PM

#

if you're actually telling me i can't run tests on any part of my project because i have a missing { in one file in one package, then you clearly dont know how to use junit

dusky harness Mar 29, 2022, 11:04 PM

#

dusky harness or

or delete the other files (or comment them out and delete all their usages)

graceful hedge Mar 29, 2022, 11:05 PM

Like if you wanna test your code, obv ti needs to be compile-able

dusky harness Mar 29, 2022, 11:05 PM

#

pearl topaz if you're actually telling me i can't run tests on any part of my project becaus...

junit isn't the cause here

pearl topaz Mar 29, 2022, 11:05 PM

#

graceful hedge Like if you wanna test your code, obv ti needs to be compile-able

i'm not testing the code that i cant compile lmao

#

that's the whole point

#

there is no reference to any of that code

#

in my tests

#

or the classes used in my tests

graceful hedge Mar 29, 2022, 11:05 PM

#

And?

#

You don’t seem to know how this test procedure goes exactly

pearl topaz Mar 29, 2022, 11:05 PM

#

bruh can literally anyone else respond

dusky harness Mar 29, 2022, 11:05 PM

#

if you run gradle build, just because spigot might not use some of your code doesn't mean that it can have errors

pearl topaz Mar 29, 2022, 11:05 PM

#

you are clearly misunderstanding

dusky harness Mar 29, 2022, 11:06 PM

#

same thing here, except that instead of spigot it's junit

graceful hedge Mar 29, 2022, 11:06 PM

#

No, like even if you have the class com.dkim.FinalizableAbstractFactory which does not compile, but is still in source, then of course you won’t be able to run tests for the source

#

because junit isn’t some magical wizard that can figure out every little interdependence of every unit you have

#

The task compileJava is fundamentally integral to pass in order for the tests to run, that’s just how it works, even though your test might not depend on the entire code base, but only the compiling parts

#

If some parts still don’t compile, it won’t run the tests as it can’t for sure know whether the failing parts are crucial to the actual compiling parts that you’re essentially testing

#

And yes this is ofc caused by IntelliJ (possibly gradle) in principle, altho for good reasons, you could in principle go and compile the test src for yourself and then run the tests but that’s just masochistic

u have to OS code generated by copilot?

hoary scarab Mar 30, 2022, 12:49 AM

Not currently. But it's not your code if it's generated by ai lol

dusky harness Mar 30, 2022, 12:50 AM

but that also means it's not someone else's code fingerguns

hoary scarab Mar 30, 2022, 12:51 AM

Technically it would mean it's github's code

lyric gyro Mar 30, 2022, 12:51 AM

#

The training samples are from OS repos, but the generated code isn't necessarily generated from them, depending on context and what you do exactly it can come up with something that is not out there

#

It can stitch things together or, yes, copy code from existing repos

pulsar ferry Mar 30, 2022, 12:51 AM

It also generates from samples from your own code

lyric gyro Mar 30, 2022, 12:54 AM

It's scary sometimes

I just want them to add function to do suggestion with a shortcut similar to ctrl + space

As far as I know, only open that side bar

Disable live completion suggestions and use the "Open Copilot" thingy

pulsar ferry Mar 30, 2022, 12:55 AM

#

Yeah that's not what I mean though, I mean like the current way it suggests but manual

lyric gyro Mar 30, 2022, 12:56 AM

#

It definitely needs more configuration on the plugin side of things

#

Which should be trivial!

pulsar ferry Mar 30, 2022, 12:56 AM

#

Yeah, then I would turn it back on

pearl topaz Mar 30, 2022, 1:14 PM

#

i have a class i'm extending from with a method i want to override

override fun addAndGet(operand: Int): Int {
    this.value?.add(operand)
    logValue()
    return this.value?.toInt() ?: 0
}
```however, `this.value` is nullable as the class needs to be able to be instantiated without a value, then set one later. i can't change the return type to `Int?` as the method i'm overriding returns `Int`

#

what's good practice for this? ?: 0 is a temp fix

kind granite Mar 30, 2022, 1:16 PM

#

give it a default value

pearl topaz Mar 30, 2022, 1:16 PM

#

ah yes

#

smart

#

or else i could do return this.value?.toInt() ?: throw NullPointerException("Value is not set")

sterile hinge Mar 30, 2022, 1:17 PM

#

well what happens if the method is called before the value is set initially?

pearl topaz Mar 30, 2022, 1:17 PM

#

somethin like that

pearl topaz Mar 30, 2022, 1:17 PM

#

sterile hinge well what happens if the method is called before the value is set initially?

well right now it just returns 0 and does nothing

sterile hinge Mar 30, 2022, 1:18 PM

#

and what would you like it to do?

kind granite Mar 30, 2022, 1:18 PM

#

or define it as lateinit and just make sure you set it

pearl topaz Mar 30, 2022, 1:18 PM

#

feel like a default value is the easiest way to go

sterile hinge Mar 30, 2022, 1:19 PM

#

like, if you don't want someone to call the method before the value was set, you should throw an exception

#

lateinit sounds like a good approach ig

kind granite Mar 30, 2022, 1:20 PM

#

it's literally what lateinit is designed for

pearl topaz Mar 30, 2022, 1:23 PM

#

kind granite it's literally what lateinit is designed for

is it? i can't guarantee that the value will be set though

#

so i'm a bit confused

#

as to what it actually achieves

#

like sure i hope it's set before they try and do operations on the value

#

but how is that different

kind granite Mar 30, 2022, 1:24 PM

#

how come you need to be able to instantiate it without a value?

pearl topaz Mar 30, 2022, 1:25 PM

#

it's in the spec i was given, not certain tbf

#

maybe i'll just remove that

#

unless you can explain the lateinit thing or why it helps

pulsar ferry Mar 30, 2022, 1:26 PM

#

Only difference would be that lateinit will throw an error if you access it without initializing it

pearl topaz Mar 30, 2022, 1:35 PM

#

what's the appropriate way of accepting a parameter when i want to immediately change its type? i have a parameter to my class value: Int that i run MutableInt(value) on

#

right now i'm doing

class IntLogger(private val intValue: Int) {
    var value : MutableInt = MutableInt(intValue)
}```

#

i never use intValue again

#

i just want to be able to instantiate with a regular int

kind granite Mar 30, 2022, 1:42 PM

#

what youve got there is fine

pearl topaz Mar 30, 2022, 1:46 PM

#

ok thanks

#

i'm really confused about extending actually

#

class IntLogger(private val intValue: Int) : MutableInt(), Logger {

#

i'm trying to extend from the class MutableInt

#

but it's making me initialise it

#

then whenever i try use methods from MutableInt, it just thinks the value of my IntLogger is 0

#

if i initialise it with MutableInt(intValue) then it just wont change when i change the value of IntLogger

#

this seems bizarre, why would i want two "versions" of my object here? i just want one IntLogger instance that can access the methods from MutableInt

kind granite Mar 30, 2022, 1:53 PM

#

there you're creating a logger that is a mutable int

#

mutableint is a class itself

#

logger is just an interface

#

which is quite a strange way of doing what you're trying to achieve

#

what is the end goal?

pearl topaz Mar 30, 2022, 1:55 PM

#

i'm trying to make my own MutableInt, where i override all the setter methods to log the value change

kind granite Mar 30, 2022, 1:55 PM

#

ah

#

that is not what a Logger does

pearl topaz Mar 30, 2022, 1:55 PM

#

the way it's working now, there's one value returned by logger.getValue() (defined in IntLogger) and another returned from logger.intValue() (not defined in IntLogger)

#

i know 🙂 this is a trivial explanation, i'm confident of that though

#

i just need to get this extend working

kind granite Mar 30, 2022, 1:56 PM

#

are you familiar with calling methods on super

pearl topaz Mar 30, 2022, 1:56 PM

#

yes

kind granite Mar 30, 2022, 1:56 PM

#

do that

#

inject a logger in the constructor

#

shim each method and log to that logger

pearl topaz Mar 30, 2022, 2:01 PM

#

this is v confusing

kind granite Mar 30, 2022, 2:01 PM

#

yes

#

except you don't need to override methods that just call the super

#

    override fun serialise(): String {
        return super.toString()
    }``` does basically nothing

#

and you don't need the value variable, that's defined in super too

pearl topaz Mar 30, 2022, 2:02 PM

#

but the value in super is Int, my value is MutableInt

kind granite Mar 30, 2022, 2:03 PM

#

your value doesn't exist

#

the class itself is a mutableint

#

we're only shimming the mutableint class, we don't care about what's happening in the class itself

pearl topaz Mar 30, 2022, 2:05 PM

#

ok i think i get it

kind granite Mar 30, 2022, 2:05 PM

#

also don't implement logger

pearl topaz Mar 30, 2022, 2:06 PM

#

kind granite also don't implement logger

wdym?

kind granite Mar 30, 2022, 2:07 PM

#

your class implements logger

#

don't do that

pearl topaz Mar 30, 2022, 2:07 PM

#

logger is my own interface

kind granite Mar 30, 2022, 2:07 PM

#

it should write to a logger, it is not a logger itself

#

oh

#

be aware that can be very easily confused for java.util.Logger which does something slighly different

wheat carbon Mar 30, 2022, 2:07 PM

#

however, i can't seem to get it to work since ArrayList has no getValue() method

#

val targetStream = ByteArrayOutputStream()
val out = ObjectOutputStream(targetStream)
out.writeObject(super.getValue()) // write our serialised object to the output stream
val serialisedValue = targetStream.toByteArray() // get serialised byte array
out.close()
targetStream.close()
Base64.getEncoder().encodeToString(serialisedValue) // encode byte array to String with B64
```like i just want to do this

dense drift Mar 30, 2022, 3:26 PM

#

what even is an ArrayLogger?

pearl topaz Mar 30, 2022, 3:27 PM

#

dense drift what even is an ArrayLogger?

just a class i've made which writes to a logger everytime a set operation is made

#

so i'm overloading set, add etc in ArrayList

kind granite Mar 30, 2022, 3:28 PM

#

why are you serialising for logging

#

that seems like a bad idea

#

in fact why do you even need that, it sounds like a very backwards debugging technique

dense drift Mar 30, 2022, 3:28 PM

#

info(x.toString()) ?

pearl topaz Mar 30, 2022, 3:29 PM

#

i was trying to abstract some details but maybe not helpful

#

the logging is using redis

#

which only stores strings

#

so i need a serialise and a deserialiseAndSet method for ArrayLogger

pearl topaz Mar 30, 2022, 3:30 PM

#

dense drift info(x.toString()) ?

dont think this is consistent

kind granite Mar 30, 2022, 3:30 PM

#

serialisation is not human readable

#

which is pointless for logging

pearl topaz Mar 30, 2022, 3:31 PM

#

sorry i have complicated it

#

i know that it needs to be serialised

#

this method works except for when i switched to super

#

when i was just storing the value in ArrayLogger, it worked fine

#

but i can't do super.getValue()

#

so i have no idea how to serialise/deserialise it

kind granite Mar 30, 2022, 3:32 PM

#

explain what you're trying to do from a high level

pearl topaz Mar 30, 2022, 3:33 PM

#

i'm trying to create a class (let's call it ArrayLogger) that overloads any method inside ArrayList that updates any of its value

kind granite Mar 30, 2022, 3:33 PM

#

to do what?

pearl topaz Mar 30, 2022, 3:33 PM

#

and if that happens, i write the new value to a Redis DB

#

which has to be serialised to a string as that's all redis takes

kind granite Mar 30, 2022, 3:33 PM

#

so a redis-backed array?

#

sounds like you need an orm

Oh alr

kind granite Mar 30, 2022, 3:46 PM

#

what

#

have you ever considered just returning this

pearl topaz Mar 30, 2022, 3:46 PM

#

no idea what you mean tbf

kind granite Mar 30, 2022, 3:47 PM

#

fun getValue() = this

pearl topaz Mar 30, 2022, 3:47 PM

#

that wont return the value of super though will it?

#

as an ArrayList<T>

kind granite Mar 30, 2022, 3:47 PM

#

this and super are the same object

pearl topaz Mar 30, 2022, 3:47 PM

#

that will give me an ArrayLogger<T>

kind granite Mar 30, 2022, 3:48 PM

#

super is used to access methods defined in the superclass, but still refers to itself

lyric gyro Mar 30, 2022, 3:48 PM

#

ArrayLogger is an ArrayList

kind granite Mar 30, 2022, 3:48 PM

#

good old liskov substitution principle

lyric gyro Mar 30, 2022, 3:48 PM

#

if you really want to be pedantic about the return type being an ArrayList then fun getValue(): ArrayList<T> = this

kind granite Mar 30, 2022, 3:49 PM

#

i believe its from a generic interface

pearl topaz Mar 30, 2022, 3:49 PM

#

i replaced your getValue() with mine and it broke the serialisation

#

so it must not be equivalent

#

i mean

#

replaced mine with yours

kind granite Mar 30, 2022, 3:49 PM

#

i have so many questions

#

why are you trying to serialise stuff

#

what is the purpose of putting all this stuff in redis

lyric gyro Mar 30, 2022, 3:50 PM

#

to start with I don't think extending the types you're supposed to store is good design

pearl topaz Mar 30, 2022, 3:51 PM

#

lyric gyro to start with I don't think extending the types you're supposed to store is good...

how would you approach overloading the methods?

kind granite Mar 30, 2022, 3:51 PM

#

dont do that

lyric gyro Mar 30, 2022, 3:51 PM

#

either don't do it at all or make use of kotlin's by delegation/proxying

#

inclined towards the first option

How could i disable taking out items, putting in items, dragging items from my gui?

Current code(Not Working):

    @EventHandler
    public void onInventoryClick(final InventoryClickEvent e) {
        if (!e.getInventory().equals(inv)) return;
            if(e.getCurrentItem() == null) return;
                if(e.getCurrentItem().getItemMeta() == null) return;
                    if(e.getCurrentItem().getItemMeta().getDisplayName() == null) return;
                        e.setCancelled(true);
                            Player player = (Player) e.getWhoClicked();
                            if(e.getSlot() == 22) {
                                player.sendMessage("test");
        }
    }

no. them

👍

broken elbow Mar 30, 2022, 6:02 PM

#

why the indentation xD

pearl topaz Mar 30, 2022, 8:06 PM

#

lyric gyro either don't do it at all or make use of kotlin's `by` delegation/proxying

i'm still quite confused by what you mean here

#

i looked into it but couldnt figure out why it's applicable

kind granite Mar 30, 2022, 8:07 PM

#

as in the delegation bit?

pearl topaz Mar 30, 2022, 8:07 PM

#

yeah

#

or any other way to approach it

#

i have an API that updates the value of this class

#

so surely i need a setValue method

#

since arraylist doesn't provide one

kind granite Mar 30, 2022, 8:08 PM

#

setting an arrays value to another array doesn't make sense

#

like when would you ever do that

#

why do you need that method

pearl topaz Mar 30, 2022, 8:08 PM

#

when i have a wrapper class that's monitoring something, and that instance starts monitoring something else

kind granite Mar 30, 2022, 8:09 PM

#

setting a list's value to another list is not a list

#

at that point its more of a list container

pearl topaz Mar 30, 2022, 8:09 PM

#

that's what it is

kind granite Mar 30, 2022, 8:11 PM

#

then it's not a list

#

so don't override ArrayList

pearl topaz Mar 30, 2022, 8:12 PM

#

so just write it all myself? or what

#

what's the difference there though

kind granite Mar 30, 2022, 8:12 PM

#

what you have there is effectively a mutable reference

#

for primitives, that works

#

for lists that does not

#

which is why the approach youre taking is not suitable

pearl topaz Mar 30, 2022, 8:14 PM

#

i dont see another approach

kind granite Mar 30, 2022, 8:15 PM

#

what is the end goal

#

what are you trying to achieve by logging mutations and storing them on a redis server

pearl topaz Mar 30, 2022, 8:16 PM

#

it's just for fun mostly, like a telemetry service

#

everything else works just stuck on arraylist

lyric gyro Mar 30, 2022, 8:17 PM

#

having fun much? 🥲

pearl topaz Mar 30, 2022, 8:18 PM

#

yeah mostly tbf

Have you tried using print statements/logging to find if the function is returning when it shouldn't be? that's where i'd look first

if (!e.getInventory().equals(inv)) return;

Check for the name of the inv

#

Cause i think he can't find the inventory to cancel the items dragging etc

pearl topaz Mar 31, 2022, 12:37 AM

#

what's the correct way to implement a global variable that's used between multiple classes? i have a single map accessed in my main loop but also in the Ktor REST API

#

i was planning on making the methods @Synchronized

#

companion object?

#

is it just as simple as

#

and when i update it in either, they both change?
