[proud pebble]

then i just modify the item's lore to have all enchantments on it

its not the best solution probably but it works

having to check for the enchantment manually is also kinda a pain

[hoary scarab]

It's just for adding the glow so I would just add unbreaking or something if I can't get it to work.

[proud pebble]

i add the glow enchant by using protection 0

protection's effect calculation is (4*level)%

so if its level 0 it doesnt boost it

[hoary scarab]

It's not for useable items so it won't affect anything.

[proud pebble]

fair enough

[fading stag]

Is it not possible to give potion effect higher than duration 32767 ticks (2^15-1)
I can't give more than that, using 1.8 (I know, it is outdated, but not my preference) looks like a ViaVersion issue

[rigid mountain]

Question, Im just getting back into making some plugins in my free time. And iv always wondered about this. So is it not static abuse to use singleton to construct an instance of a class and do ThatClass.getInstance()? Or is that fine to use static for something like this? The previous ways iv done this is having a instance in the Main class and refrencing that, but then i have to pass in the main class to every class I want to use it in

if that makes any sense at all..

[dusky harness]

I mean technically bukkit does this already with JavaPlugin.getPlugin, Bukkit.getPluginManager(), and JavaPlugin.getProvidingPlugin, so I guess in the end it technically doesn't really matter, but I think that it would be considered static abuse, yes
edit: had some other info/explanation here but it kinda doesn't make sense for this case so
for why it's bad, feel free to google that part :))

Dependency Injection
Dependency Injection is a way of providing objects with the objects they need ("dependencies"). This is usually done with a constructor, but can also be done for individual methods

[rigid mountain]

Alright thanks, I juse DI for most things I was just curious

[merry knoll]

static and singleton pattern are mainly an issue due to unit testability

DI allows you to mock modules while testing

[graceful hedge]

It can also be a design issue long term, and you do have powermocks to mock static stuff (though if you actually need powermocks, jokes on you)

Ye why not

[fading stag]

tried using PotionMeta but it just didn't work

Do you mean splash or lingering?

[fading stag]

splash

[rigid mountain]

Anyone have a good guide for unit testings?

[graceful hedge]

There are some really good books about it I can give you

But yea ru just aiming to learn how to unit test (like using Junit in java with mockito etc?) or do you want to learn unit tests in the industry as well as test practices such as tdd?

[signal grove]

does anyone know an instance where a tameable can be owned by a non entity?

or why does this even require a cast

[torpid raft]

looking at the docs, an offline player can be an animal tamer

so yeah if the owner is an offline player that wont be an entity

[signal grove]

ahh i see, thanks

[proud pebble]

a player can be an entity but an offline player isnt

[sonic nebula]

Owner can be only player

check the interface wtf

u can cast / manipulate do something tricky

[signal grove]

thanks team

[proud pebble]

yes, but it doesnt mean the owner is online

and since offline player isnt an entity ,thats why its not set as entity

[river solstice]

i assume spawners spawn and seeds grow and are regulated by main thread. if so, is it possible, without folia, to move them to separate thread? even if it involves some sketchy methods

[dusky harness]

for seeds, you can modify spigot.yml and set the wheat modifier to a negative number
for spawners, you can modify the paper config for the world and set the mob spawner tick rate to -1

if you want to edit it using a plugin, you'd have to modify the server jar or edit the config via reflection

[river solstice]

but they are still being ticked on the main thread? Im not looking for a way to disable growing or spawning, just move it to a separate thread. Though my understanding of how it works might be a bit wrong, or if it was possible then it would of probably be already done.

[hoary scarab]

Nothing like that would be possible without heavly modifying the server jar.

[river solstice]

oof

might start looking into modifying paper

[hoary scarab]

You might beable to disable the ticking then make your own threads and run the NMS methods.

[dusky harness]

ohhh

then yeah you need to modify the server jar

sorry i completely misunderstood/misread lol

[river solstice]

on a scale of 1-10, how difficult would it be to modify the paper jar? assuming someone with fairly good java knowledge

[river solstice]

all good, I might have not been clear enough of my intention

[dusky harness]

i think paper gives a guide and so you just edit it and then ij makes a diff file (at least I'm assuming/hoping that the devs aren't manually typing out diffs?)

[dusky harness]

nono I was digging through the server code and forgot what the intention was 💀 but I can tell you where the code that you probably want is

at least as of paper 1.20.1
net.minecraft.world.level.BaseSpawner line 82 (serverTick)
net.minecraft.world.level.block.CropBlock line 72 (randomTick)

[river solstice]

Might just hire someone to do that since I dont have much time to do so lol

[dusky harness]

🥲

[river solstice]

is what i'm trying to do would even do any good in terms of performance?

cuz I assume if it was it probably would have been done already in some shape or form

[hoary scarab]

If you have the source it really shouldn't be that hard just remove the code from the worlds tick method. Then have your own thread running the methods you want multi threaded.

[sterile hinge]

I doubt there would be much benefit, especially considering there is no way to do that without at least breaking plugins

[hoary scarab]

It has... Folia lol

[river solstice]

yeah, but folia isnt really an option for me lol

[sterile hinge]

Folia doesn't do specific things off the main thread, it splits the world into multiple regions

[hoary scarab]

Whats your server type?

[river solstice]

cant check rn but we have around 40 plugins

a lot of them rely on events

[hoary scarab]

Gamemode* Skyblock, survival, factions?

[river solstice]

survival

mostly relies on spawners and farms, hence the idea

[hoary scarab]

Then your server is what folia was made for lol

[sterile hinge]

I mean, just think about how many plugins are written in a way that they support what you're trying to do

[river solstice]

hmm. i guess ill try running folia on a testserver and check the damages

[dusky harness]

oh if this is for your server then you can run spark to see if its actually needed

[river solstice]

funnily enough folia if translated letter by letter would sound like folija in my language which means tinfoil

[river solstice]

eh, well, been doing a lot of profiling as of lately, found some minor issues but thats about it

[hoary scarab]

Yeah definitely gonna be a challenge finding which plugins support folia since its not even fully supported itself lol.
You could ask @spare marsh though as I see him requesting plugins to be modified for folia alot.

[river solstice]

recently upgraded from 5900x to 7950x3d and ddr5 but have only seen a slight degrade in performance

been wondering why is that the case

[hoary scarab]

Bottleneck from your motherboard?

[river solstice]

also the server owner insists on running the server on 30gb+ ram, though from what I know it's not ideal, plus I've noticed on grafana that we only use about 14-15 lol

[sterile hinge]

that's definitely too much for G1GC

[river solstice]

thats with 180+ players

[hoary scarab]

Survival with a big online playerbase, I can see the need for 30gb.

[river solstice]

yeah I will check the jvm flags, I remember tinkering around with it, not sure if they are the most optimal though

[dusky harness]

more memory can lead to longer GC times though afaik
Don't know the specifics but I think that's what SirYwell meant

[sterile hinge]

yes

[hoary scarab]

Ah true

[dusky harness]

i think you can view gc times in spark though

[sterile hinge]

GenZGC won't have a problem with that though

[merry knoll]

depends on which gc you use

[river solstice]

uh im not even sure what we are using, since we are renting a DS

[dusky harness]

g1gc
don't know much about other gcs 🥲

[merry knoll]

zgc can handle terabytes of heap no issue

[river solstice]

oddly enough I can't even check the manufacturer of the RAM, all the ubuntu commands show it as undefined lol

[hoary scarab]

I assumed you upgraded the parts. Yeah might be something you should ask your host about. If you can prove it ofcourse.

[river solstice]

I mean 5900x uses AM4 and 7950x3d AM5, so cant be due to using an old MB, though they could have cheaped out on it

[torpid raft]

could be that it's too new

no decent software support yet, maybe

[spare marsh]

Depending on the plugin I may or may not lol. All the plugins I have been using have been ported.

[torpid raft]

although the 7000 series came out in 2022 according to google so that doesnt seem that recent any more

[spare marsh]

Even if I don’t most plugins have alternatives you can use.

Hello, I was wondering how do I build DeluxeMenus on Ubuntu? I tried ./gradlew build, but it doesn't work? It just says permission denied.

[dusky harness]

try running chmod +x gradlew

that should give permission

[spare marsh]

Huh now it says " -bash: ./gradlew: /bin/sh^M: bad interpreter: No such file or directory " despite me cloaning and such. Here is the log ( https://mclo.gs/B0h9zHp )

[dusky harness]

is this on a Windows pc?

or an actual linux computer

[spare marsh]

Yes I am on windows, but I am using ubuntu

[dusky harness]

try doing it without the ubuntu
you'd just run gradlew.bat shadowJar in command prompt after cloning the git repository

then it should be in build/libs/DeluxeMenus-1.41.1-DEV-null.jar

alternatively you can try the solution this solution in ubuntu: https://askubuntu.com/a/305001

but note that you probably need gradlew(.bat) shadowJar

not build

[spare marsh]

Oh okay. I don't have gradlw on my terminal, so I'd have to install it. In the meanwhile I was wondering if it wasn't possible to build it using Ubuntu? Alternatively, shouldn't intellj work too?

[dusky harness]

you don't need gradle installed, that's the wonderful thing about gradle 🤩 (since its all in the project files)

and yes intellij and ubuntu should both work

[spare marsh]

Thanks!

Does constructing an armorstand (or any entity) using new EntityArmorStand(world, x, y, z) cache the object anywhere?
I brought this up before when I was showing how physics aren't applied to these entities but pistons are somehow able to push them.

I looked through all the constructors and super classes and can't find anywhere that it would cache this object so I don't see how a piston is able to move it while everything else is negated.

[icy shadow]

it's impossible for constructors to perform caching, they always make a brand new object

[atomic trail]

What is the reason for not being able to change variables in lambda functions?

Is smth like this bad?

[hoary scarab]

Not what I meant.
I'm looking for where the entity is stored after its constructed... but just based off the constructors I'm not seeing anywhere the object is cached (added to a list, map etc...)

So how is a piston getting the entity to push after its constructed?

[icy shadow]

not bad, but you might as well just use a for loop - also AtomicDouble is a thing

FAQ Answer:

Online Courses:
Online courses are also great for learning java. Some websites that offer them are:

• Coursera - Free unless you want a certificate
• PluralSight - Great courses from what I've seen. Mostly Paid
• Udemy - Never used them myself but they seem to all or at least most be paid.
  My first ever course was one from Coursera. - I can say it was pretty good at introducing me to the programming world as a whole not just java.

Oracle Docs:
Oracle docs can help a lot at learning and understanding java:

• Start with this,
• Breeze through this (skipping stuff that doesn't seem relevant like bitwise operators),
• Hit this.
  They're the first three from this larger thing which you should definitely go through overall. But those three should be enough for slightly better understanding of what is happening here without feeling like a huge time sink.
  That one is a small part of this larger site wherein "Essential Java Classes" and "Collections" also have good useful stuff

Other services:
Some other cool services that will help you learn java are:

• SoloLearn
• W3Schools
• JetBrains Academy

As you can see there are plenty of good ways to learn as long as you're willing to invest the time. Have fun learning!

Requested by: bristermitten • learn-java

[icy shadow]

focus on having a good knowledge of java first, then the spigot stuff will be easy

other way around is very hard

[edgy pelican]

I know a bit of python

how long would it take me to learn?

[hoary scarab]

Read javadocs, open source plugins, tutorials etc...

[icy shadow]

anywhere from a few days to a few years, depends on the person

[icy shadow]

thats a good start, though theyre fairly different languages. it might help you get the basics down

[atomic trail]

Yeah makes sense, it's because the function works like functional programming right? Immutable variables or whatever

[icy shadow]

that's not the reason why

but kind of

there are 2 good explanations that i like

the first is that it's because java is pass by value, not pass by reference

which is the actual reason why

the second is that suppose you could do something like this, this code would be legal: ```java
void blah() {
int x = 0
Runnable r = () -> {
x = 1;
}
runTaskLater(r, 1000);
}

by the time that `r` runs, the method has finished, and so `x` doesn't exist anymore

it's already been cleaned up

[atomic trail]

Ohhh yeah well that makes sense, but does lambda work the same way? I thought it would still run in sync with everything else

[icy shadow]

well no, the whole point of lambdas is to capture a computation that you can run at arbitrary points

how would it sync? would blah() not finish until r runs?

[atomic trail]

So this wouldn't necessarily get the final amount?

            AtomicReference<Double> autosellMoney = new AtomicReference<>((double) 0);
            event.getItems().forEach(item -> {
                autosellMoney.updateAndGet(v -> /* update blah*/);
            });

            double finalAutosell = autosellMoney.get();

Just imagine its atomic double

Changing it now lol

[icy shadow]

sure, in this case it's fine

because you know that forEach will actually run the function every time

but the compiler doesn't

just to be clear, this isn't the actual reason why this isn't allowed

[icy shadow]

this is

[icy shadow]

but i think this reason is more intuitive because it shows how even if it was possible it would cause weird behaviour

[atomic trail]

Oh I thought what you meant was that the code under the foreach function would potentially run after, like it was async

But yeah I just changed to a regular foreach

[icy shadow]

nah its cuz the lambda might try and change a variable that doesnt exist anymore

maybe this isnt the best explanation since it relies on you knowing about the java memory model a bit

[atomic trail]

Yeah not sure I understand why lol

Because wouldn't the variable always exist if the code still runs in order from top to bottom?

Or well obviously not but yeah

I don't understand why

[icy shadow]

it doesn't run in order

you create the lambda without running it, the method finishes, and then the last line jumps back to the lambda body 1000ms later

thats the important bit, the 1000ms

[dark garnet]

I'm working on a plugin and want SQL support. Since I've change some major things I need to rewrite my sql code and need some help with how to do it. Currently I have a proxy that saves in local java.io.File objects or in a MySQL db depending on settings. I realised that this is kinda annoying and would like to just save them all in a db so that I don't need implementation for both Files and SQL. So, is it possible to store the data in a local MySQL file or smth? If so, can someone give me an idea where to start looking, internet is useless and I can't find anything helpful on the topic.

[torpid raft]

you can use SQLite if you want a local database

Currently learning java using w3schls, finished everything in the tutorial, now will be learning java methods. any tips/ advice?

Keep it simple, there is usually more than one way to solve a problem, your code is fine - you don’t always have to correct yourself after every opinion or programmer meta you hear of :) gl

Also, no lombok

[river solstice]

yes lombok

🦅

stop writing 100s of getters and setters, builders manually, use a single annotation

🦅🦅🇺🇸🇺🇸

[warm steppe]

use records

[worn jasper]

they are good but not mutable lol

also, lombok is good and bad at the same time tbh

Records are suppose to not be edited.

[dusky harness]

You mentioned you were learning methods next - that's fine

[edgy pelican]

Java seems easy so far, does it increase in difficulty?

[dusky harness]

Oh that's very good lol

But if you are just learning methods, there's still a bit more to learn

I'd also recommend learning gradle
Its an unofficial build tool used to manage projects (ex if you want to add spigot to your project, you'd tell gradle that) and to actually create the jar file
Another build tool is maven, but gradle is preferred

But depending on your stage, it might be too early to learn gradle (since it won't be necessary)

Then after that, just Google like "spigot gradle" and probably follow spigot tutorials from there

There's no set path to follow so don't take my words or anyone's too seriously for how to progress

What's the best way to handle open-ended text as variables within placeholders?

For example, example_<text>_var1_var2 where <text> could potentially include underscores, what's the best way to handle that? Quotes?

I haven't used PlaceholderAPI before, so I don't know how other developers tend to do that, but I'd like to keep the syntax consistent

Try surrounding the type.build line with try/catch since it throws an exception

uhh
threads, inner classes, user input, date, linkedlist, iterator, regex
can also skip abstraction since you're probably not going to use that anytime soon

oh okay that's good

[edgy pelican]

can someone explain encapsulation ?

i dont understand the concept behind get and set

and this too

[proud pebble]

if you had your variables a public then one piece of code could modify it at any time with any value, getters and setters exist so you can put limits on what that value can be and to exit before its changed

[edgy pelican]

oh

are getters and setters located in the private class?

or outside of it

[proud pebble]

inside the class

[edgy pelican]

and are private classes read only? or no read

[proud pebble]

the class is public, the getter and setter methods are public, but the variables are private

[edgy pelican]

the public class?

[proud pebble]

private classes cannot be accessed afaik from anywhere, its unlikely you would make a class private unless its an inner class

[edgy pelican]

public class Main {
  public static void main(String[] args) {
    Person myObj = new Person();
    myObj.name = "John";
    System.out.println(myObj.name);
  }
}

   private String name;

   // Getter
   public String getName() {
     return name;
   }

   // Setter
   public void setName(String newName) {
     this.name = newName;
   }
}

code i find confusing

the get and set are inside of the private class, so what are they doing?

are they moving data (to the main class)? or

[proud pebble]

in the main() attempting to call myObj.name would throw an error

[brazen elm]

^

you can't get the values that are private

you can ONLY get the private value from the parent class itself

minus reflection but that's too advanced rn

[edgy pelican]

  public static void main(String[] args) {
    Person myObj = new Person();
    myObj.setName("John");
    System.out.println(myObj.getName());
  }
}```

```public class Person {
   private String name;

   // Getter
   public String getName() {
     return name;
   }

   // Setter
   public void setName(String newName) {
     this.name = newName;
   }
}

what about this?

[brazen elm]

that would work

since the method is public

[proud pebble]

that wouldnt error, because those functions/methods are public

[edgy pelican]

so things can be public in a private class

[proud pebble]

public, private and protected are all access modifiers

thats not a private class

[edgy pelican]

oh

was reading the wrong thing

[brazen elm]

private = only the parent class can access it
protected = only the classes inside the parent PACKAGE can access it
public = every class can access it (theoretically)

[proud pebble]

nearly all classes you have inside of a project will be public

[edgy pelican]

oh this makes sense, the name variable is private, but since it's in the same class it can access it, so the getter get's the variable and stores it, and sets it to newName which can be accessed by another class

[brazen elm]

yeah

the method is public therefore that would work. But if the method was private that would throw an error since the main method doesn't have access to it

[edgy pelican]

so you would make another public methodd in the class getting and setting the private method so it can be used by the main class

[brazen elm]

yeah

basically

[edgy pelican]

oh, rad

[brazen elm]

and non-static variables are stored inside the object whenever you create a class object

static variables are stored inside the class which isn't created everytime you create an object of the class

to my understanding, idk how it works under the hood but ik when to use them 💀

[proud pebble]

static variables are created when it registers that the class exists

you dont even have to call new for those variables to register

[edgy pelican]

anything i should know about any of this going forward?

[proud pebble]

if you want to call static variables, then you have to do ClassName.variable

[edgy pelican]

i think i'm gonna call it a day, currently im using w3schools https://www.w3schools.com/java/, i finished the tutorial yesterday, now i'm moving onto Packages / API

[proud pebble]

or if you are using a getter/setter, they have to be declared as static aswell

[edgy pelican]

i need to familiarise myself more with keywords

hopefully after time my memory an understanding will increase

[brazen elm]

also be careful about static abuse, here's a link for better understanding: https://stackoverflow.com/questions/11906913/java-static-vs-instance

[edgy pelican]

what's instance?

[dusky harness]

not sure if you figured it out already but basically, getters and setters allow you to control the data being set and get as Lunaiskey mentioned
But even if you're not doing anything with the data (other than setting and getting), if you didn't have getters/setters but wanted to add them later, you'd have to change all of the code from person.name -> person.getName()/person.setName()
So having getters/setters from the start avoids that

[proud pebble]

when you call for example, Person person = new Person(), the person variable is now holding an instance of Person

its basically just a copy

[edgy pelican]

what's an alternative, instead of opening the same instance, it opens like a cloned instance basically so that both can have and edit the same value but differently

[proud pebble]

just make another variable

[brazen elm]

and looks way better sometimes

[dusky harness]

https://i.imgur.com/z00fqmT.png
😌 Lunaiskey you should take the java quiz

[edgy pelican]

   public static int x = 5;

 }

Test t1 = new Test();   
Test t2 = new Test();```

would it turn into 

public class Test{

public instance int x = 5;

}

Test t1 = new Test();
Test t2 = new Test();

[dusky harness]

no, you'd just remove the static keyword (public int x = 5;) - note that it should be private though because encapsulation

[edgy pelican]

oh, just get and set it

yeah that seems cool

[edgy pelican]

anyways, @dusky harness , @brazen elm and @proud pebble , nice discussion we've had lol. I'll be going offline now. Thanks for all of your help to broaden my understanding about Java.

[brazen elm]

lmao

[proud pebble]

thought it was yaml for a hot second, also for the array i was thinking when you declare the contents of an array like {1,2,3} unless im completely dense and it is [1,2,3]

[brazen elm]

nope

that's a char

single quotes

🙂

[dusky harness]

mixing java and yaml 🥲

[brazen elm]

xD

it happens!

[proud pebble]

well in yaml you can just do 'easports'

i think its the same in json aswell

[dusky harness]

no json is strictly "

😌

[proud pebble]

then how i fucked that up idk

im too used to ide telling me im shit change that

[prisma vault]

If it doesn't matter what type of player I need to use, should I use the onRequest(OfflinePlayer, String) method or the onPlaceholderRequest(Player, String) method?

[brazen elm]

I dont think it matters too much, personally I'd use the Player one

[dusky harness]

the first one just calls the second one if you don't override it, so use whichever you need

just note that because of that, the second one won't work if you use the first one

[forest jay]

ok github copilot, I didnt need to be reminded

[brazen elm]

Lmao

[merry knoll]

might want to take a look into what instances are (and what static is) in the future once you are familiar with the basics

Hello there, I am trying to hide player x name tag from player y, by sending a armor stand spawn packet to player y, that is attached to player x. I'm stuck on attaching the armor stand as a passenger. I noticed the Mount packet only takes one argument and that confuses me, couldn't really find anything online.

[hoary scarab]

... If you want to hide players from each other you can use Player.hidePlayer(Player)

[edgy flume]

I want to hide the name tag, my bad

[hoary scarab]

Ah

[cloud panther]

just want some advice, currently working on a plugin and every friday at 00:00:00, i want the plugin to run a certain method, is there an event i can use ?

[dusky harness]

I would just run a bukkit scheduler for every second or something and check the time using https://stackoverflow.com/a/26097080/14105665 and https://www.geeksforgeeks.org/localdate-getdayofweek-method-in-java/ (both use LocalDate)

[cloud panther]

ah thank you

[dark garnet]

should i do that for a discord bot too (except not a bukkit scheduler obv...)? been trying to use some library but it just dont work

[dusky harness]

you can use ScheduledExecutorService

tbh that's probably the best solution for Walter as well, but I didn't feel like doing research 🥲

[dark garnet]

yeye, i tried using something called Quartz, just never worked

[dusky harness]

uhh

[dense drift]

Quartz is a lib for cronjobs iirc

Question regarding GitHub and Verified Domains. I've followed the steps to verify a domain and it did verify it but after a while it sent me an email to reverify. This has happened twice now. I can't see this specified anywhere but I've removed the TXT Record after verification. Anyone know if this might be the issue or if this is just normal?

[broken elbow]

I went ahead and reverified and didn't remove the TXT Record. We'll see if it happens again or not.

[light pendant]

Can I somehow get rid of this unchecked cast warning? I know that in java I can't check the generic type, I guess in kotlin I cannot do it either, right?

[dusky harness]

there's reified but it won't work here, so nope - type erasure 🙃

[light pendant]

stupid compiler, doesn't see that I check isSUperclassOf 🥲

[sterile hinge]

use asSubclass

don't know if that works with Kotlin

in your YourClass.java

import something.else.thing

public class YourClass { //<== outer/main bit of the class
    
  public int doSomething() {
    return (new YourInnerClass()).getVar();
  }

  public class YourInnerClass { 
    //inner class, these can be nested classes if
    //you wish to do that.
    public int variable = 0;

    public int getVar() {
      return variable;
    }
  }
    
}

basically an example

[river solstice]

https://tenor.com/view/outraygeous-shrimple-outrageous-eagle-ray-gif-27253586

non static inner class !!!

[sterile hinge]

an inner class is always non-static, otherwise it would be a nested class

if(enemydistance > 5){
Shoot(entity);
} else {
StabInTheHead(entity)
}
} else {
RunAway
}

something like that can i do with custom entity pathfinder goal

like writing on pathfindergoal ofc

and also cast abilites how would u do it by a task or there some sort of priority in entity goals?

like there is i know i have checked the net.minecraft default mobs

i mean vanilla but yeah

it has like goal(intger,jerk around); and etc etc

hello, i want to store simple integer to acces it throught placeholderapi

What's the best way to handle it? and prevent losing the data on server crash and make it optimized so it doesnt read and lookup every second the data.yml file?

[tame jungle]

Just load from file on startup and save periodically. @ripe gull

[merry knoll]

or save on change and keep a cache for papi

[ripe gull]

can i see somewhere an example of the implementation

[edgy pelican]

ok, i did the w3schools guide, now what do i do to make my java skills the best/learn how to develop in spigot

[dusky harness]

practice

hold on

[edgy pelican]

alr, msg when your here

[dusky harness]

https://www.spigotmc.org/threads/challenges.235525/#post-2378547

piggy is an admin in this server btw

i dont think hes really active recently tho

[edgy pelican]

what api do i use?

how do i even create the plugin thing in intelij?

[dusky harness]

oh wait oops yeah I forgot to mention that lol

[edgy pelican]

thx

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

found this

[dusky harness]

spigot should have a wiki tho

[edgy pelican]

couldn't see it

[dusky harness]

hold on kinda busy atm ill link more soon

https://www.spigotmc.org/wiki/build-you-spigot-plugin-with-gradle-groovy/ @edgy pelican

https://www.spigotmc.org/wiki/spigot-plugin-development/

[dusky harness]

look at this url, then these

oh and this

[dusky harness]

(from this url)

[edgy pelican]

any difference between making it in paper? or in spigot

@dusky harness

[dusky harness]

best is paper, but for simplicity, I'd stick to spigot for now

or actually tbh

yeah just stick to spigot for now

[edgy pelican]

what's the difference?

[dusky harness]

paper has a lot of additions

but also "removes"/unrecommends/deprecates some spigot stuff that you should probably know

[dark garnet]

"some" is an understatement

[dusky harness]

I originally wrote "many" but edited it 🥲 because idk how to english that

[dark garnet]

it deprecates anything that doesnt use adventure 😭

[dusky harness]

🥲
adventure better tho

[edgy pelican]

i love adventure

such a cool lib

[dusky harness]

oh if you know adventure already

then

you know this would be a great time to advertise galaxy gradle

[edgy pelican]

ill learn the developmental side too

[dusky harness]

but for the sake of knowing the behind the scenes

[edgy pelican]

spigot?

sure

[dark garnet]

oh right i added adventure support to that i forgot

[dusky harness]

😮

[dark garnet]

COUGH https://gradle-galaxy.srnyx.com

[dusky harness]

hey that was stolen inspired by DkimGradle

[dark garnet]

sorry i had something stuck in my throat

[dark garnet]

never heard of it

[dark garnet]

btw i recommend spigot

as it just widens userbase, but if u need paper-specific stuff then use paper

[edgy pelican]

paper is much more efficient

but sure ill develop in spigot

which build system?

[dusky harness]

GRAdle

Gradle

Gradle

GraADle

[dark garnet]

up to u tbh, a majority of ppl use paper already anyways; https://bstats.org/plugin/bukkit/EssentialsX/858#serverSoftware

[dark garnet]

GRADLE

[edgy pelican]

paper-plugin.yml

ill start with paper i guess

[dark garnet]

yeah paper (sorta) recently made its entirely own plugin registration/loader thingy

[dusky harness]

uh

i would advise using spigot first

[edgy pelican]

oh

[dusky harness]

paper server

[dark garnet]

oh right this is first-time sorry

[dark garnet]

wdym efficient btw?

[edgy pelican]

like,compared to spigot as a server .jar

[dark garnet]

u can use paper server jar even if u develop with spigot

[edgy pelican]

group.id?

[dusky harness]

ur domain

if u have one

[dark garnet]

ex: xyz.srnyx or com.srnyx

[edgy pelican]

does it have to be?

[dusky harness]

i do me.dkim19375

¯_(ツ)_/¯

it doesn't have to be official

[dark garnet]

u can just make it up

[dusky harness]

i used me.dkim19375 then like 2 years later bought dkim19375.me

[dark garnet]

💀

[dusky harness]

¯_(ツ)_/¯

[dark garnet]

yeah thats the only thing u gotta keep in mind

its used to identify ur code

so its best to use something u can acquire later yknow (or already have)

[edgy pelican]

ye true

[dark garnet]

wish i had used com.srnyx :(

[dusky harness]

tbh i like xyz more

[edgy pelican]

fr

xyz good

artifact id?

[dusky harness]

project name lowercase no space no underscore no dash

no symbol

actually are there supposed to be dashes?

idk i dont use dashes tho

[dark garnet]

yeah i dont either

[edgy pelican]

what??

[dusky harness]

like coolplugin

for example

or bedwars

[edgy pelican]

just named it first

version?

[dusky harness]

btw to recap: https://www.spigotmc.org/wiki/spigot-plugin-development/
do these: https://i.imgur.com/jnGKUYG.png
and you can also try out https://www.spigotmc.org/threads/challenges.235525/#post-2378547 later

[dusky harness]

0.0.1

¯_(ツ)_/¯

[dark garnet]

0.0.1 for dev builds smh u should know this

[dusky harness]

oh uh

[dark garnet]

wait i dont even use group.id i dont think

[dusky harness]

?

:)

[dark garnet]

omg

[dark garnet]

i just set rootProject.name in settings.gradle.kts

(and not lowercase, ex: LaserTag)

[dusky harness]

thats supposed to be in settings.gradle.kts

well thats what intellij does so

¯_(ツ)_/¯

[dark garnet]

?

:)

[dusky harness]

SMh

[dark garnet]

so what the heck is artifact id

[dusky harness]

like in maven dependencies

you know

theres the groupid:artifactid:version

[ripe gull]

    public static void loadData() {
        FileConfiguration config = YamlConfiguration.loadConfiguration(new File(PlayerGreetRewards.plugin.getDataFolder(), "data.yml"));
        for (String key : config.getKeys(false)) {
            UUID uuid = UUID.fromString(key);
            int greetings = config.getInt(key);
            greetData.put(uuid, greetings);
        }
    }

    public static void saveData() {
        FileConfiguration config = YamlConfiguration.loadConfiguration(new File(PlayerGreetRewards.plugin.getDataFolder(), "data.yml"));
        for (UUID uuid : greetData.keySet()) {
            config.set(uuid.toString(), greetData.get(uuid));
        }
        try {
            config.save(new File(PlayerGreetRewards.plugin.getDataFolder(), "data.yml"));
        } catch (IOException e) {
            e.printStackTrace();
        }
    }```

is this the correct way of caching my data?

[dark garnet]

oh, isnt it not needed for spigot plugins? like it dont do anything

[dusky harness]

ig not but intellij auto adds it so i just have it 🤷

[dark garnet]

oh lmao

[dusky harness]

although i don't use intellij project maker for java anymore 😌

should make ur own project generator

[dark garnet]

i just have a template lmao

how would project generator even work

[dark garnet]

i assume greetData is a map?

if so, it looks good, but i usually store/cache the YamlConfiguration too (or whatever YamlConfiguration#loadConfiguration(File) outputs i forget)

[ripe gull]

hashmap

[dark garnet]

yeye

[ripe gull]

So now, every 5 minutes i saveData() and loadData()?

or what

[dark garnet]

u should just be able to save every 5 mins, not have to load

[dusky harness]

well it uses some templates but it also automatically fetches latest versions, automatically configures based off what you say, etc

tried finding a video but couldn't find :(

[dark garnet]

but like what language

[dusky harness]

kotlin

[dark garnet]

so is it like a script/program?

separate? or is a gradle plugin

[dusky harness]

whole program

then i do java -jar

[ripe gull]

so my loadData() is useless then?

[dark garnet]

no u run that when plugin starts

(and/or in ur plugin's reload cmd if u have one)

[dusky harness]

and i have a bunch of templates that it uses

[dark garnet]

send me the program.

[dusky harness]

um

well you see

its kinda personalized 🥲

so its closed source

BUT

it could be a fun project to code

[dark garnet]

WDYM?!

[dark garnet]

i dont wanna!!!!111!!!11!!!1 i just wanna steal ur code1!1!111!!!!!!

[dusky harness]

its in kotlin 💀

also its kinda broken rn

the placeholder system isn't working

[dark garnet]

so?! i can learn kotlin!!

[dusky harness]

uh

[ripe gull]

Sooo, now it will be cached for my PlaceholderAPI?

[dark garnet]

i dont understand

[dusky harness]

it can be a fun first kotlin project 😃

[ripe gull]

i want my data to be stored to use it in PlaceholderAPI

[dark garnet]

imma cry

[ripe gull]

and i dont want the PlaceholderAPI to look for the user every second in data.yml file, i want it to be cached in map

[dark garnet]

alr yea if u use ur greetData map to get the data for the placeholder it should be good 👍

[ripe gull]

okay thanks

[ripe gull]

so now when i change values, i do it only on the map, and saveData() every like 5 minutes?

this approach is okay?

[dark garnet]

yes, only risk is if server crashes, data wont be saved (unless it was saved recently yknow)

[ripe gull]

so maximally can be lost data from up to 5 minutes

awesome

[merry knoll]

public class CacheExample {


    private final HashMap<UUID, Integer> cache = new HashMap<UUID, Integer>();

    public void setGreeting(UUID uuid, int greeting) {
        cache.put(uuid, greeting);
        // save to file, ideally async idk what you are using as "file"
    }

    public int getGreeting(UUID uuid) {
        return cache.get(uuid);
    }
}

or you can do a file save every x amount of changes if these change constantly

[ripe gull]

so i save to file every time i change the value?

[ripe gull]

    public static void saveData() {
        FileConfiguration config = YamlConfiguration.loadConfiguration(new File(PlayerGreetRewards.plugin.getDataFolder(), "data.yml"));
        for (UUID uuid : greetData.keySet()) {
            config.set(uuid.toString(), greetData.get(uuid));
        }
        try {
            config.save(new File(PlayerGreetRewards.plugin.getDataFolder(), "data.yml"));
        } catch (IOException e) {
            e.printStackTrace();
        }
    }```

im using a file data.yml

[merry knoll]

it depends on how often its changed

[ripe gull]

rarily

i wrote a plugin to reward players on greeting a new player on chat

and i want to store how many players you have greeted

[merry knoll]

on change should be fine then, also if you are using ymlconfiguration

cache the instance and use that

[ripe gull]

what does that mean

[merry knoll]

one sec

[ripe gull]

i had an idea of storing it in PDC

but what about offline players?

[merry knoll]

public class CacheExample {


    private final HashMap<UUID, Integer> cache = new HashMap<>();
    private final Set<UUID> changes = new HashSet<>();
    private final FileConfiguration config;
    private final int saveDelay;


    public CacheExample(YamlConfiguration config, int saveDelay) {
        this.config = config;
        this.saveDelay = saveDelay;
    }

    public void setGreeting(UUID uuid, int greeting) {
        cache.put(uuid, greeting);
        changes.add(uuid);

        if(changes.size() >= saveDelay) saveToFile();
    }

    public int getGreeting(UUID uuid) {
        return cache.get(uuid);
    }

    private void saveToFile() {
        try {
            for (UUID changed : changes) {
                config.set(changed.toString(), cache.get(changed));
            }

            config.save();
            changes.clear();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

something like this

[merry knoll]

you probably have a database running

ideally you would just store there

[ripe gull]

maybe then sqlite?

[merry knoll]

if you use it already would work fine

just a basic table

with uuid - smallint

uuid as primary key

[ripe gull]

which is easier to implement

[merry knoll]

both are simple but the issue with yml is that

you load all of the file

whenever you do yamlconfiguration

[brazen elm]

sqlite

[merry knoll]

so its not exactly scalable if your player count that greet increase

[brazen elm]

its faster

and ain't that hard to code a complete database

[merry knoll]

its not like you code anything

just gotta add sqlite jdbc driver

so jar size goes up

[brazen elm]

uh no?

java has the jdbc driver for one

and two, you still need to add a connection and sql strings

[merry knoll]

since when jvm has jdbc driver by default

[brazen elm]

since like ever

[merry knoll]

huh lemme try

[brazen elm]

import java.io.File
import java.sql.Connection
import java.sql.DriverManager
import java.sql.SQLException```

prob not the BEST way to do it but idc

https://pastes.dev/BxxUD9G5v6

and its kotlin so

[merry knoll]

ya but you need the driver itself no?

[brazen elm]

not for sqlite

for mysql you do

and you dont need to close the connection in sqlite which is nice

[merry knoll]

ah, i probably just assumed its not in there

and just added through maven

never tried honestly

[brazen elm]

all the other databases you need to close the connection everytime

idk i like sqlite but people like other things

[merry knoll]

@ripe gull a basic example for you

[brazen elm]

mongodb, mysql, ect

[merry knoll]

i mean if you are doing relational

you would probably do postgres

instead of mysql regardless

[brazen elm]

fair enough

i've honestly never touched postgres yet

wanting too

or surrealdb

i wanna try both of them

cuz sqlite doesn't support arrays 😦

[merry knoll]

if you can use mysql you can use postgres

[brazen elm]

gotta make your own serialization with it

you need to edit the params as needed

[merry knoll]

this is more of a database design smell

[brazen elm]

yeah 😓

[merry knoll]

what you can do instead is have another table

[brazen elm]

yeah that is true but i'd still personally perfer arrays but its whatever

i usually just use another table cuz im lazy to setup another database

since sqlite is automatically setup for ya

[merry knoll]

what do you need exactly?

just uuid to int?

[brazen elm]

mehh

not rlly

yml is slowest of all of them

json MAYBE, but i'd still recommend a database

[merry knoll]

it really doesnt matter at 50 - 100 total players

barely any data

[brazen elm]

i mean as long as you aren't writing to the file constantly you should be fine ig

[merry knoll]

write every 5 - 10 changes

and do it async and you good

on another thread

[brazen elm]

running on a different thread

use a BukkitRunnable or CompletableFuture imo

although a CompletableFuture is a thread pool so

i'd do every 5 minutes and everytime they join / leave

i usually set it up like that

[merry knoll]

saving every x time is wasteful

[brazen elm]

could also do a little bonus thing and make it so it doesn't unload from memory until like 5 minutes after the player leaves incase they relog

[brazen elm]

not rlly imo, just helps if the server does crash

i wouldn't do every minute but

but i get what you're saying

dont write to the file everytime a value changes

do it like every 5 minutes and when they leave / join then you should be fine

[merry knoll]

https://paste.helpch.at/enujetetal.java

here

[brazen elm]

i wonder if you could write a batch system for yaml

never tried

[merry knoll]

you end up editing the whole file regardless i think

unless you do your own yaml handler from scratch

https://paste.helpch.at/yicibopixo.java here use this instead did a small oopsie on the set

with mutable state

[brazen elm]

i mean when i started learning java i used simplexstorage

it has a batch system and everything you really need

https://github.com/Simplix-Softworks/SimplixStorage

i use it sometimes cuz spigot's api for yaml configuration is actually doodoo

[merry knoll]

i barely do yml anyway

[brazen elm]

i mean i only use it when i make a public plugin with a config ofc

that's it

[merry knoll]

altho i stopped writing anything minecraft for couple of years now

[brazen elm]

oh that's fair

mc development has really gotten boring recently

ik other languages just idk what to make in them so i just stuck with java

and decided to learn kotlin like a week ago

[merry knoll]

kotlin is fun

especially coroutines

[brazen elm]

kotlin is epic

it has nice syntax imo and has an expanded stdlib from java

kotlin's methods in collections are great, really saves some time. And their kt extentions are epic too

[merry knoll]

it just doesnt force oop down your throat

and allow you to write functionally if needed

[brazen elm]

fr

https://pastes.dev/cBhTAfbFAk

simple leaderboard system in kotlin

would be a bit more complex in java

[merry knoll]

with streams it should be similar

[brazen elm]

i mean prob i was looking at the sortedByDescending and its just a comparable so

[merry knoll]

later java versions are really not that bad anymore

unless you are forced to work with j8

[brazen elm]

yeah

java has improved, especially in 21 with new collections and such

but most of the good things that were announced are in preview

[merry knoll]

@ripe gull you good now?

[brazen elm]

and honestly, idk who tf decided to do string templates like they did in java but i really dont like how they did it

[merry knoll]

virtual threads etc are the main hype

honestly

[brazen elm]

its like swift and meh

STR."\{firstName} \{lastName}"``` this looks dogwater imo

i'd much rather ${}

[brazen elm]

yeah those will be nice

[merry knoll]

ya, the way effectively every new language does it

is the way to go

my only issue with java atm is null safety

Optionals are way too verbose

dont forget to call the saveData() method on server shutdown if you are using the code i sent

[brazen elm]

erm

anyone know of a better way of doing this?: https://pastes.dev/dyHTqH2cBp

trying to rotate a vector depending on the living entities yaw

that works just wondering how i could improve it

[royal hedge]

Id vector ur own type

Cuz if it is make it a data class and u can destructure it woth val (vx, ...) = vector or smth lile that

[sterile hinge]

You can simply look that up, but it’s mostly people who are working on the language for decades, and they typically have even more experience in that field. The choices they make aren’t just for fun, they are based on many reasons, trying to get a compromise that integrates well with rhetoric language in general

And "I don’t like the syntax" is like the weakest form of complaint, and it was also discussed and considered, and the decision was made because the facts are in favor of it

[brazen elm]

still dislike it but not my language really. And swift does the same thing

i moved to kotlin recently anyways so it doesn't really impact me that much

[sterile hinge]

Yeah Kotlin only has basic string interpolation anyway, so that’s not comparable at all

[turbid hornet]

how fix getMaximumAge?

   @EventHandler
    public void Farm(BlockBreakEvent event) {

        World world = Bukkit.getWorld("world");

        if (event.getBlock().getWorld() == world) {

           Block block = event.getBlock();
           Player player = event.getPlayer();

           Material cropBlockType = null;

           if (block.getType() == Material.WHEAT) {

            Inventory inv = player.getInventory();
            cropBlockType = Material.WHEAT;

            Ageable age = (Ageable) block.getBlockData();
            int getMaximumAge = age.getMaximumAge();


           }
        }
    }

age.getMaximumAge

don`t worlk

[dusky harness]

what part about it doesn't work?

like what's the issue with getMaximumAge?

[terse osprey]

I think I remember running into this issue awhile ago, im not at my pc so can’t double check, but what you’re after is Material.CROPS not WHEAT

Edit: This was a fix for older versions of MC, in recent versions WHEAT is correct.

[proud pebble]

did you make sure to import the correct ageable as there is 2

cropBlockType seems redundant

you could get hte world and just check if the name is equal to "world" instead of using getworld and checking if they are equal since afaik its possible that both world objects might not be

[turbid hornet]

No, this variable is so that I can configure the world in which it is spent, so that I don't want to change the entire code.

[turbid hornet]

I know

My version is 1.19 Paper

[turbid hornet]

didn`t work

[terse osprey]

Can we see your imports as well. And “didn’t work” isn’t all that descriptive, is it producing an error?

[turbid hornet]

import org.bukkit.Bukkit;
import org.bukkit.Material;
import org.bukkit.World;
import org.bukkit.block.Block;
import org.bukkit.entity.Ageable;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.block.BlockBreakEvent;
import org.bukkit.inventory.Inventory;

[turbid hornet]

It doesn't give an error in IntelIj Ethla, its color is red, as if it doesn't exist

[terse osprey]

As #development message said, you imported the wrong Ageable, what you're after is import org.bukkit.block.data.Ageable; NOT import org.bukkit.entity.Ageable;

[turbid hornet]

oh thank you

[merry knoll]

you can only do thread safe stuff async

[sonic nebula]

helllo

dears

i cant do trial and error from diff reasons

but scoreboard packets once sent it stays till new update? same Tab list?

or u need to update schedulerly or everytick

thanks to the answers.

[pulsar ferry]

It stays

[sonic nebula]

so for performance for player side , i would need to send packet only on update correct?

ill think about how to manange performance better thanks Matt.

[pulsar ferry]

Sounds like premature optimization, but yes it makes more sense to only send when it needs to update

[quartz briar]

I've generated jars for this project with BuildTools with the --remapped flag, then loaded them in the individual version directories with mvn install:install-file, but still face an error along the lines of what is below for every NMS version. I have no idea what do, help please.

found the right ones under Spigot-API

nevermind, that did not help

[stuck canopy]

Is there a way to implement a class on CraftingRecipe or RecipeChoice and have that recipe registered.
I tried implementing upon RecipeChoice but that did not work. There are two RecipeChoice. ExactChoice which allows you to add multiple ItemStacks for detection (assuming it uses ItemStack#isSimilar or ItemStack#equals to detect). MaterialChoice which allows you to add multiple Materials for detection.
I am trying to add a Custom ItemStack detecting system (e.g if I only want to check for the ItemStack's (in the matrix) name or persistentdata, etc). Do I have to create my own recipe manager to check for recipes and their results using PrepareItemCraftEvent
OR is there any better way to do this?

[dusky harness]

I don't use maven, but I think you should be using the maven dependency

edit: below, plus you can just buy the plugin too :))

[light pendant]

when using maven + spigot I'd highly suggest to use mojang maps + the specialsource plugin for remapping https://blog.jeff-media.com/nms-use-mojang-mappings-for-your-spigot-plugins/

gradle question: I have declared a libs versioncatalog in settings.gradle.kts like this:

dependencyResolutionManagement {
    versionCatalogs {
        create("libs") {
            plugin("shadow", "com.github.johnrengelman.shadow").version("8.1.1")
        }
    }
}

However I cannot access that in my buildSrc/build.gradle.kts - anyone got any idea?

I however can access "libs" in all other build.gradle.kts files, just not in buildSrc - am I doing sth wrong or sth?

[pulsar ferry]

buildSrc is a separate project and currently it doesn't have access to anything from the root project, not even the gradle.properties
You need to declare the version catalog in the buildSrc's gradle.settings.kts
Also you can't make it a plugin if you want it to be accessible in the buildSrc's build.gradle.kts's dependencies block, you'd need to make it a library

[light pendant]

oh ok that's sad. I thought I could avoid having to declare things twice using the version catalog, but then it won't work. Well I'll just keep the version hardcoded then, thanks

[pulsar ferry]

If you have a version catalog file, then you can get away from declaring it twice then on the buildSrc's settings you can do

 versionCatalogs {
    register("libs") {
        from(files("../gradle/libs.versions.toml"))
    }
}

To import the catalog from the file

[flint kernel]

why register the catalog manually? gradle recognises that one by default

[minor summit]

read up

[flint kernel]

i see

yeah i ran into that issue too

when trying that

really annoying

[light pendant]

oh yeah that's a good idea. thanks

[light pendant]

alrighty that works fine except for in actual scripts in buildSrc/.../kotlin/bla.gradle.kts files. It still cannot find the "libs" thing there, so I currently use this:

dependencies {
    api(project.versionCatalogs.named("libs").findLibrary("acf-paper").get())
}

that can't be the correct way I guess?

as you can see, it works in my buildSrc/build.gradle.kts file, but not in actual buildSrc scripts

[royal hedge]

libs isnt availabke in precompiled scripts theres an issue for it but doesnt look like its gonna get resolved

[light pendant]

oh alright, thanks! Then I'll just use my workaround from above, but good to know that there's an issue for it open 👍

[queen plank]

I'm adding SQL support for one of my plugins and have found a problem I can't find a good solution to. My plugin allows users to, among other things, edit custom items. I want these items to be saved in the SQL db.
So, say I start my server and it loads all items from the db and I then proceed to edit the item. When the item is edited it of course has to be saved so the changes are pushed to the SQL db. However, right as my changes were saved to the db another server auto-saved all items to the db, and so my work was overwritten? What would be the best way of solving this? I've thought about adding like an "updates" column to the row and compare those, would this be a good way of doing it?
Also, how would I do for other players editing the item? Should I just not update the SQL db if someone else has updated it while I was editing it? That will again ruin my work. Should I just don't care and let it be a problem for the servers owners or should I "lock" the items, and if so what would be the best way of doing so?

Please ping me if you respond :)

[hoary scarab]

Could also save the time it was saved and if it was edited in the last 30 seconds or so take both items and merge the edits from the original.

[quartz briar]

not trying to avoid buying the plugin, im adding support for a pets plugin

[dusky harness]

see what mfnalex posted below; I don't have maven experience, but mvn install:install-file doesn't seem like it should be used here

[quartz briar]

thanks for that article, I used NMS a while ago, and forgot that BuildTools automatically adds it to your .m2 repo. thx!!

[light pendant]

np!

[light pendant]

install:install-file is basically the manual version - it's used to install arbitrary .jars to the local repo, while the regular mvn install while install whatever the current project has produced. so yeah, you use install-file if you downloaded a random .jar file that you wanna install, and you use mvn install to install whatever your currenct project has "produced"

buildtools simply runs mvn install on the spigot-api and spigot project

[dusty frost]

Yeah locking the row in the DB would be your best bet imo. Then it eliminates any race conditions. Hard part is actually doing it, depending on how many SQL distributions you support. I know Postgres has some very good row-level locking stuff, iirc MySQL/MariaDB have something that can do that? something like sql SELECT item FROM `items` WHERE id = 3 FOR UPDATE or similar

[queen plank]

Well I can’t really merge them. Say the original is a diamond sword with sharpness 1. One player changes it to an iron pickaxe with efficiency 1 and another player changes it to an iron axe with sharpness 1 and unbreaking 1. How do I merge that? I can’t really?

[flint kernel]

thinkin what's "FOR UPDATE do

[queen plank]

I thought about this and how to do it. But I have a few problems. Say a player starts editing the item, and then the server gets shutdown incorrectly and the server does not have time to unlock it again, them what? Do I make the owner unlock them all manually? Is there a good way of reliably locking/unlocking rows like this?

[dusty frost]

iirc it locks the rows "for update"

then once you do update the rows later it removes the lock

[flint kernel]

hmm, cool

[dusty frost]

Some sort of timeout system maybe? Honestly not sure lol

[queen plank]

Yeah that’s the problem I keep coming back to lol. My current best idea is having a ”updates” column, then telling a player wanting to save data that ”the item has been updated x amount of times since you started editing, do you really want to undo the previous changes?” or smth?

How’d I do the timeout as well lol? If the server is offline it can’t do it it self. Do I make a new column or table for it?

[dusty frost]

Could do something like a cache table, then when you're done editing it can check the timestamp of when you started and see if it has been updated since, then give players a "This item has been updated since you started editing, would you like to overwrite?", and if they say yes, you flush the changes to the table

[queen plank]

Yeah exactly. That’s where I’m at rn, just think an updates field to show ”it has been updated x amount of times” instead of ”it has been updated” seems nicer

[dusty frost]

I mean, what's the timeframe on this kind of stuff?

are people editing items for like, hours? how many times is a single item going to be updated while you're editing?

[hoary scarab]

Is this per server? Maybe update the item to the player live.

[queen plank]

Not very often I’d imagine. Very rarely I think. Though I will probably get some angry users complaining abt it. Though the major thing is other servers backing up data and replaceing new data. Maybe I can flag the items or compare update timestamps etc?

[queen plank]

What do you mean, dont really understand?

Like fetch the new data with each update?

[dusty frost]

Why would other servers completely erase all item data?

Surely you just touch it once and then that's how it is until the next time someone updates it

[queen plank]

I currently have the servers auto saving data. But now that I think abt it I really don’t need that lmao. If I just saves the changes when they are made all is fine lol. Smort

Ig I’ll just compare timestaps and ask users if they wanna make the changes. Seems like the best idea so far?

[dusty frost]

yea

[queen plank]

Oki then, thanks for your help :)

[pulsar ferry]

There is a hack you can use to get libs working in the precompiled scripts
On the build.gradle.kts add implementation(files(libs.javaClass.superclass.protectionDomain.codeSource.location)) in the dependencies
Then on the precompiled script you can do val libs = the<LibrariesForLibs>() and libs will be available

[light pendant]

interesting, I'll try that, thanks

[light pendant]

uughm wdym with "the" at "the<LibrariesForLibs>" part?

[pulsar ferry]

It's a gradle function

[light pendant]

oh wow you're right lol

yay! thanks

[pulsar ferry]

Yw ;p

[light pendant]

only downside is I gotta use the<...> in every script right? I cannot move this into an extension function or sth?

[pulsar ferry]

Yeah you have to use it on every script
There might be something you can do about it though, give me a sec let me try something

[light pendant]

// Libs.kt
fun Project.libs(): LibrariesForLibs {
    return the<LibrariesForLibs>()
}

// Any other buildSrc script
dependencies {
    api(libs().acf.paper)
}

Got it to work like this now! Thanks for the idea, works great :3

[pulsar ferry]

Yeah, or

val Project.libs: LibrariesForLibs
    get() = the<LibrariesForLibs>()

I saw this somewhere I am curious how they did it. Supposedly by manipulating a TextDisplay you can move the text up and down. This was used so that if the entity had a name already, the plugin could shift the text display upwards. the only way I can see this working would be by setting a line width and having an empty character wrap over to the next line, shifting the previous line up, just not sure how to achieve that as the documentation on TextDisplays is terrible.

Does anyone know how to achieve this?

      .a(...)
      .b(Optional.ofNullable(obj)
               .map(List::stream)
               .map(stream -> stream.filter(Objects::nonNull))
      ...
}

idk I prefer using something like this

[royal hedge]

huh? you prefer that instead of

return Struc.builder()
     .a(...)
    .b(obj
        .stream()
        .filter(Objects::nonNull))
    ...

?

oh wait nvm

but why u got a nullable list

thats an anti pattern

i mean i get when doing nested chaining stuff itll look kinda ugly so i get that, but if its like just Optional.ofNullable(foo.bar()).orElse("") then its a little unnecessary

I have a message that runs when the player leaves the server but the placeholders in the message just get replaced with nothing. I assume the player needs to be online for them. specifically with luckperms placeholder. wasnt sure if its something with the plugin i made or placeholderapi

@EventHandler(priority = EventPriority.LOWEST)
    public void quitEvent(PlayerQuitEvent event) {
        // other code

        player.sendMessage(PlaceholderAPI.setPlaceholders(player, message));
}

[topaz gust]

You may need to preprocess the message when they are online and give it back yourself when you need it aka a map memory storage or something similar.

As them being offline will likely be the issue depends on the placeholder though

thought so, thanks

I have a bunch of ”Component” classes that include multiple ”Parameter” fields each. I need to show this data (component name and description + parameter name and description) on my GitBook wiki. Is there a good way of converting this automatically? If not it will be a nightmare to do by hand, and near impossible to keep up to date and maintain.

Please ping me if you respond :)

[sterile hinge]

there are many ways I guess

one would be annotation processing directly

another would be using a library that understands java and can extract the data you want

@queen plank

[queen plank]

The data itself isn’t too hard to extract. The problem I can’t solve is how to get said data to the gitbook wiki. I need to create tables, bold text etc..

[sterile hinge]

you could probably make use of some sort of templating framework

[queen plank]

Do you know any that could be of help?

[sterile hinge]

I don't have any experience with a specific template engine, but e.g. https://www.baeldung.com/mustache looks like it could do what you want

[queen plank]

Looks useful, thank you!
