[ivory sleet]

Just expose setters of the field?

[analog ore]

but it adds OOP messiness

oh

[ivory sleet]

No need to have that container thing?

[drowsy helm]

would be a bit faster, but you are saving so much space not attributing all the variables just for one field

[ivory sleet]

anyways avoid reflection if you can, it can complexify your code very easily

[analog ore]

I'm basically doing that, just.. with a bit extra OOP.

I could ditch the field wrappers

[drowsy helm]

key, value, defaultVal, timeToLive,loaded, loader, client, connection

all just for one variable

[analog ore]

yup

[drowsy helm]

you're saving time but imagine that with like 10k fields

[analog ore]

hm.

[ivory sleet]

Thing is wertik right now your entire memory model is tightly coupled to redis

[analog ore]

sacrificing memory

[ivory sleet]

Maybe you want that but it looks a bit fragile from my pov

[analog ore]

it does

i'll rethink the structure

but it was intended to run purely with redis

[drowsy helm]

also is the AdderTaker field just a incrementation interface?

[ivory sleet]

Fair Wertik I guess in that case

[analog ore]

it is, but it's there for more complex fields that require more (de)serialization

[drowsy helm]

gotcha

[analog ore]

it's true that I could use a setter

but that would make the "driver" less general

I planned on removing the User class from it and using it as a library for more model structures

depending on a setter would remove that possibility wouldn't it

[ivory sleet]

Wertik I’d recommend handling the invalidatation of fields of the user externally rather than as an implementation detail of the user

So maybe some sort of UserHousekeeper

Then just have pure fields

No generic containers or that

[analog ore]

yh

that feels smoother and more solid

[ivory sleet]

Yeah but I haven’t read your code thoroughly so only you can determine what’s best 😄

[pastel stag]

@idle grotto are you meaning something like this? tbh im completely lost and this also breaks my Main class LOL ```package com.n0grief.WatchBlock.EventHandler;

import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerJoinEvent;
import com.n0grief.WatchBlock.SQL.FriendsHandler;

public class Join implements Listener {
private final FriendsHandler friendshandler;
public Join(FriendsHandler friendshandler) {
this.friendshandler = friendshandler;
}
@EventHandler
public void onJoin(PlayerJoinEvent event) {
Player player = event.getPlayer();
friendshandler.createPlayer(player);
}

}

[analog ore]

it definitely made my think about my approach

I knew the OOP was memory inneficient and overkill

[drowsy helm]

also definitely make an interface for your objects you want to be serialized

[analog ore]

yup.

didn't need it yet

[drowsy helm]

yeah you're sorta just relying on the person to implement what is needed

[ivory sleet]

But back to your original question, if you have enough ram, definitely directly cache in the jvm short term at least (:

[drowsy helm]

looks good otherwise though

[analog ore]

yeah

thanks for you time guys

[idle grotto]

Exactly. Now in the main class pass the friendshandler in the constructor call

[drowsy helm]

all good lol

[drowsy helm]

try using a different class name like "JoinEventListener" or "JoinListener" etc

[pastel stag]

so this is the line that is broken in the main class getServer().getPluginManager().registerEvents(new Join(), this);

[drowsy helm]

new Join(this)

[analog ore]

you need to pass a FriendsHandler instance into the constructor

[analog ore]

it's probably not the main class

based on the naming

[drowsy helm]

ah yeah

[pastel stag]

soooo if im not a complete idiot then in Main im adding public FriendsHandler friendshandler; and changing the above line to getServer().getPluginManager().registerEvents(new Join(friendshandler), this); ?

[tardy delta]

should i save locations into Json?

[pastel stag]

then the ide just tells me that constructor Join() is undefined

[drowsy helm]

locations are serializable by default

no need

[pastel stag]

so also add public Join join; ?

[drowsy helm]

or you can just make your own serializer into a single string

[ivory sleet]

Just invoke serialize() and then Gson most likely will know how to handle it

[drowsy helm]

in most cases you don't need to declare the listener itself

unless you plan on acessing it later

[pastel stag]

well with doing all the above changes ive still got the same error "this.friendshandler" is null in EventHandler.Join.onJoin(Join.java:17) which is this line friendshandler.createPlayer(player); in join.java

[drowsy helm]

can i see all your code in Join

[pastel stag]

ive been stumped for like 3 days on this tbh even tho its probably dumbass simple to solve lol

yeah

this is what it was originally b4 i asked for help ```package com.n0grief.WatchBlock.EventHandler;

import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerJoinEvent;
import com.n0grief.WatchBlock.SQL.FriendsHandler;

public class Join implements Listener {
public FriendsHandler friendshandler;
@EventHandler
public void onJoin(PlayerJoinEvent event) {
Player player = event.getPlayer();
friendshandler.createPlayer(player);
}

}

[analog ore]

there's an issue with the world reference, will prob have to do a (de)serializer

[drowsy helm]

yep

[pastel stag]

this is what it is now ```package com.n0grief.WatchBlock.EventHandler;

import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerJoinEvent;
import com.n0grief.WatchBlock.SQL.FriendsHandler;

public class Join implements Listener {
private final FriendsHandler friendshandler;
public Join(FriendsHandler friendshandler) {
this.friendshandler = friendshandler;
}
@EventHandler
public void onJoin(PlayerJoinEvent event) {
Player player = event.getPlayer();
friendshandler.createPlayer(player);
}

}

[drowsy helm]

looks fine to me

also lower camel case

so "friendsHandler"

oh i see

you aren't declaring a new friendHandler in your main

[ivory sleet]

Oh yeah

Will probably have to create a delegating World -> CraftWorld serializer

[pastel stag]

sooooo this.friendshandler = new FriendsHandler(this);

added to main?

[drowsy helm]

yep

[pastel stag]

ok. that works

[analog ore]

I always did World <-> name

[pastel stag]

but i also have no fucking idea what i did or why it works now

lmao

[drowsy helm]

Try and structure your main like this

public class MyPlugin extends JavaPlugin{
  public void onEnable(){
    initializeManagers();
    initalizeListeners();
  }

  private void initializeManagers(){
    //create managers and handlers
  }

  private void initializeListeners(){
    //create listeners
  }
}

okay what bit don't you get?

[pastel stag]

so like the main thing i don't understand is, i have other methods in another class right, and i can call on those methods in that original Join.java onJoin event that i had without any issues

[drowsy helm]

right

[pastel stag]

but pulling my createPlayer method from friendshandler didnt work in the same way

aaaand i dont understand why even tho its fixed now, and id like to understand it so next time it happens i can fix it myself lol

[drowsy helm]

ah okay

so you don't understand the null exception it was giving you right

[pastel stag]

yeah like the method is there and its accessible so i totally dont get why it didnt work when, with no other changes i could just change friendshandler.createPlayer(player); to call let's say flatlogcreator.createLog(); and it would work fine

[drowsy helm]

so say I had a two classes:

public class MyClass1{
  public void myFunction(){

  }
}

public class MyClass2{
  private MyClass1 myClass1;
  public void onEnable(){
    myClass1.myFunction();
  }
}```

your problem is similar to this: say friendsHandler was myClass1

you were declaring the variable in the

private MyClass1 myClass1

but not assigning an instance of the class to it

if you think of it as a physical object, you were saying "Here is my machine" but not actually giving a machine to work on

Java is an Object Oriented PRogramming language

so every class/object needs to actually have an instance

[analog ore]

class is basically a blueprint on how the object/instance should look like and what properties it should hold

then you construct the object from the class using a constructor

[drowsy helm]

^ thus it allows you to have multiple classes of the same type, with different values

i could have a human class, and 10 different instances of it with different name etc

[pastel stag]

so in Join.java in my case the this.friendshandler = friendshandler; creates an 'instance' of the FriendsHandler class?

[drowsy helm]

well the new FriendsHandler(this); creates the instance

you are just passing that instance through the constructor

[pastel stag]

if i say something really dumb it's cause in all honesty my knowledge of java in general is limited to like the last 2 weeks of youtube videos and wiki docs ive been able to look at lol

[drowsy helm]

we all start somewhere man

[analog ore]

we've all been there, it's alright

this.friendsHandler = new FriendsHandler(this); // <-- creates an instance from the class and assigns it to the friendsHandler variable

[drowsy helm]

yes exactly

public class Dog{
  private String name;
  private int age;

  public Dog(String name, int age){
    this.name = name;
    this.age = age;
  }
}

Dog dog1 = new Dog("Fido", 10);
Dog dog2 = new Dog("Bob", 2);

so thats an example of how i can use a class multiple times with different values

if i just do

Dog dog;
``` how is my computer supposed to know which dog im referencing

you have to tell it which dog you are referring to

[pastel stag]

So do the instances of classes always need to be created in the Main class as well?

[drowsy helm]

it doesn't have to be in the main, but for listeners and manager classes yes

Once you learn that Object Oriented Programming is LITERALLY objects, it becomes a whole lot easier lol

[pastel stag]

ok the listener thing is part of the reason i think why i wasn't able to troubleshoot this issue myself, this is the first time i've used a listener to do anything like this in the plugin

[drowsy helm]

yeah it can be confusing lol

but you only really ever want one instance of a single listener class

like if you have 10 instances of Join classes, it will repeat the code 10 times

[pastel stag]

Yeah so i mean how i'm structuring the plugin is that everything that is done on join will be in Join.java, probably all inside of that same constructor unless i see there's a reason to split stuff up, although not much is going to be done on join, just a few checks more or less

[drowsy helm]

you can always have multiple listeners of the same type

say i want something to broadcast a message on join, then say spawn a sheep on join

i would usually split that up into separate listeners

[pastel stag]

Idk if anyone is familiar with this plugin: https://dev.bukkit.org/projects/watchblock-refired - but i am basically attempting to code a plugin from scratch that does the same thing, but in a clean way, and without any prior coding knowledge lol

[drowsy helm]

never seen it but its a good project

[pastel stag]

i've learned a lot but it feels like a bottomless pit of knowledge sometimes lol, i've managed to get my plugin to create some flatlog files, utilize a config for mysql details, create a method for connecting to and checking connection status of a mysql server, and also creating 2 separate tables w/ formatting in that sql database when it first connects, other than that that's about it though

[drowsy helm]

yo thats actually really impressive for 2 weeks of java lmao

database stuff is hard

[pastel stag]

oh and i've set up a listener for block events like place and remove events that right now just sends a message to the player that did the thing w/ the coords and blocktype, which i plan to later tweak to send it to the mysql server 'blocks' table instead

[drowsy helm]

and yeah programming is just something that you can never know everything about

theres always something to learn

[pastel stag]

yeah i had a week of vacation off from work and i've found this project kinda fun, was going great, good progress every night till i hit that nullpointerexception problem lmao

[steady rapids]

is there anyone who used serialization that can help me for about 10 mins?

[drowsy helm]

yeah you start to learn how to read error codes with time, null pointer just means a value is empty

[drowsy helm]

ask away

[pastel stag]

@drowsy helm well homie thanks so much for the help w/ my side-project homie i really do appreciate it, i'm going to fix a formatting problem w/ that createPlayer() method and then i'm gunna go to bed hope you have a good night

[drowsy helm]

all good dude, gn

[steady rapids]

how do i make a class serializable? I mean, I know I have to implement ConfigurationSerializable, this makes me add a new method: public Map<String, Object> serialize(){return null} and I should be replacing this return null with a populated map of my serialized class values (i think) like the List of items, the name, posX, posY and posZ. Then what do I do with my class? how do I save its content to a file so I can load it back when needed?

public class RecipeSign implements ConfigurationSerializable {

    //list of 10 items: 1-9 are the recipes, 10 is the crafting result
    private List<ItemStack> items = new ArrayList<>();

    private String name;

    private int posX;
    private int posY;
    private int posZ;

    public RecipeSign(int posX, int posY, int posZ) {
        this.posX = posX;
        this.posY = posY;
        this.posZ = posZ;
    }

    public List<ItemStack> getItems() {
        return items;
    }

    public void setItems(List<ItemStack> items) {
        this.items = items;
    }

    public BlockVector getBlockPost(){
        return new BlockVector(posX,posY,posZ);
    }

    public int getPosX() {
        return posX;
    }

    public void setPosX(int posX) {
        this.posX = posX;
    }

    public int getPosY() {
        return posY;
    }

    public void setPosY(int posY) {
        this.posY = posY;
    }

    public int getPosZ() {
        return posZ;
    }

    public void setPosZ(int posZ) {
        this.posZ = posZ;
    }

    public String getName() {
        return name;
    }

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

    @Override
    public Map<String, Object> serialize() {
        return null;
    }
}

[quaint mantle]

how can i respawn an entity by its uuid (i saved)?

[drowsy helm]

you can just use FileConfiguration.set(path, yourObject)

[steady rapids]

I tried, and it broke when I tried to load it back :(

[drowsy helm]

oh you have to map your serialize method

to the actual fields

[steady rapids]

do u have an example?

[drowsy helm]

just create a map and for each variable set it as name, value

[steady rapids]

oh and then FileConfiguration.set and the load will work?

[sour fog]

sus

[drowsy helm]

a lot of people just make a manual methjod that serializes to a string instead

can be easier

yeah

[steady rapids]

thx

[quaint mantle]

can i somehow serialize and unserialize an entity class? to/from config

[drowsy helm]

also unrelated but if you want to reduce getter/setter methods oyu can use lombok

[steady rapids]

yeah never really used it tho

[drowsy helm]

changes```java
public class Class{
private int number;

public void setNumber(int val){
this.number = val;
}

public void getNumber(){
return this.number;
}
}

to
```java
public class Class{
  @Getter
  @Setter
  private int number;

}```

also has other annotations

[quaint mantle]

Can i somehow save a whole NBTTagCompound from entity class?

[eternal night]

There are respective methods on the internal entity representation

[mystic terrace]

How I can add Subcommands to the plugin.yml?

[eternal night]

Sub commands are not added to the plugin.yml

[mystic terrace]

I alredy did a Command manager and that stuff for subcommands, in Itellij it doesn't give me an error, but when I put it on the server it gives me this error

[hasty jackal]

you're calling getCommand() on a command that does not exist in the plugin.yml - which IDEs obviously don't check. if you're doing getCommand("mycommand") mycommand needs to be registered in the plugin.yml

this is also not a subcommand

[mystic terrace]

it is alredy

[hasty jackal]

are you sure and I mean 100% sure you're passing the right string into the getCommand() call?

given what I just glanced over in your forum post

[mystic terrace]

can I send you a paste bin?

[trail flume]

Is there a way to stop Spigot deleting empty config paths?

[eternal night]

?paste

[undone axle]

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

[hasty jackal]

I saw your forum post, I've already seen your code. Again, are you sure you're passing in the right string?

[mystic terrace]

I dunno, I'm new coding

I'm just followingn forums, posts and tutorials

[quaint mantle]

wdym

[mystic terrace]

And doing exactly what they said and I'm the only one who has this problem 🤷‍♂️

[mystic terrace]

btw, in the forum you have the plugin.yml and the code, so you can see it.

because I don't know what I'm doing bad

[hasty jackal]

I know what the issue is, I'm trying to get you to see it yourself

check what you're passing into the getCommand call and compare it with the commands you've set up in the plugin.yml

[quaint mantle]

null

it was null

i used if and else if

same problem

is there any other way to check the server's version ?

[mystic terrace]

alredy saw it

omg

reload command doesn't works :c

this one works

but /login title reload doesn't

    @Override
    public void onCommand(Player player, String [] args) {
        if(args.length == 0) {
            if (player.hasPermission("logintitle.reload")) {
                plugin.reloadConfig();
                player.sendMessage(ChatColor.GREEN + "[LoginTitle] " + ChatColor.WHITE + "Plugin reloaded succesfully");
            }
        }

    }```

[drowsy helm]

do you ever check for the reload arg

[mystic terrace]

eh?

[drowsy helm]

you are only checking perm

where do you check if its the correct argument

[mystic terrace]

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

[eternal oxide]

that is only going to do anythign if you issue the command with no arguments

From what I've read you seem to be confused over defining and registering commands

[mystic terrace]

how I can fix it then?

[eternal oxide]

what command are you typing and what do you expect it to do?

[mystic terrace]

It's a subcommand (/logintitle reload) and basically it realoads the congif.yml file.

[eternal oxide]

ok

[quaint mantle]

should just put those above the class declaration in this case

[eternal oxide]

so the actual command is logintitle the sub command (args) is reload

[mystic terrace]

yup

I have help command tho, and it works

[eternal oxide]

so in your executor for logintitle you need to see if args > 0 then check "reload".equalsIgnoreCase(args[0])

[mystic terrace]

the reload one it's the one that doesn't work

[eternal oxide]

is yoru help command /logintitle help ?

[mystic terrace]

yup

[eternal oxide]

then show us your logintitle command executor code

[mystic terrace]

?paste

[undone axle]

[mystic terrace]

My bad

[eternal oxide]

k, onme sec while I read

ok do you get an Invalid subCommand message when you try reload?

or teh command just doesn;t run?

[mystic terrace]

it doesn't run

[eternal oxide]

directly?

[mystic terrace]

mb

It doesn't run, thts all

[eternal oxide]

ok, there can only be one possible cause. You do not have the permission logintitle.reload,

[mystic terrace]

Lemme check

[eternal oxide]

your code has no issues. Its oddly designed but there are no bugs

[mystic terrace]

Im learning, so it's normal if it has an oddly design

Btw, theres a way to put that you need only op in the permission?

[eternal oxide]

yes

in plugin.yml you can add a permissions section

not a direct command permission, but a full permissions section

[mystic terrace]

doesn't works, I added the permission in Luckperms

I think the problem it's this part of the command

[eternal oxide]

there is no other issue with your code. The only possible thing is you are setting your plugin instance in your reload command to read your command name. You don;t do that for help

[eternal oxide]

Nope, nothign wrong with that

well spacing

String[] args

change the name() method to just return a String in the reload command

[mystic terrace]

imagine that was the mistake

[eternal oxide]

that will eliminate any issue with yoru plugin instance

[mystic terrace]

this?

[eternal oxide]

you have the same space issue in yoru SubCommmand class

[eternal oxide]

yes

[mystic terrace]

oke, let's test

[halcyon mica]

So, MC uses a enum to define what a block surface is for pathfinding

So I'll need to extend it

How would I do that

[eternal oxide]

Why extend it? it has every BlockFace you could need

[mystic terrace]

still without working :c

[eternal oxide]

Did you change the name() method to return a string?

[eternal oxide]

ok

and you fixed the spacing in SubCommand and reload?

[eternal oxide]

ok

then the only thing it can be is a permission issue. add a sysout in your reload command to say if there is no permission

[mystic terrace]

Like this?

[eternal oxide]

just check the permission. Don't care about op

[mystic terrace]

nope

nothing

doesn't works

[eternal oxide]

you get no output at all using /logintitle reload ?

[mystic terrace]

yup

[eternal oxide]

?paste your new reload class with the permission debug in it

[undone axle]

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

[mystic terrace]

Oke, i think now I know why it's not working

[wide coyote]

delete the first if statement and see

[mystic terrace]

basically, for no readon the plugin its not creating the config.yml file

when i didn't touched that part of the code

[halcyon mica]

I am not talking about that

I am talking about the BlockPathType

Which defines what kind of surface a block is

i.e. water border, danger, damage, trapdoor etc

[mystic terrace]

ElgarL i think I found the error

[eternal oxide]

you only need call saveDefaultConfig() in yoru onEnable. It will create the folders and copy the config from yoru jar

[mystic terrace]

 createFiles();
 instance=this;

[eternal oxide]

createFiles() is not in the paste you showed of yoru LoginTitle class

delete that method

just add saveDefaultConfig()

[mystic terrace]

where exactly?

[eternal oxide]

at teh top of your onEnable

[mystic terrace]

with this works actually, but the command still without working

[serene narwhal]

hi I'm looking for a Minecraft developer whom can program a custom plugin:

I have an issue with Mcmmo and Jobs Reborn... in the server i run i would like to remove the ablity for farms to pay out any xp or currency. (my moderators have stated this is to stop people unfairly grinding levels or inflating market prices)

the issue started with an ender mite ender man farm. and is the primary fix i would like covering but i would like this to cover all living mobs. both good and bad. (and config to change if possible)

this could be best done by targeting mobs that are close together for example mob groups of up to 5. in close proximity.

Of course commission is included and negotiable

PM me

[eternal oxide]

Paste your new reload class

[mystic terrace]

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

[eternal oxide]

Yep, delete line 12 and 21

its the only thing left it can possibly be

[mystic terrace]

finally omg

thank you so much ^^

[eternal oxide]

now you have to work out why your args is not empty is all

[mystic terrace]

it works 100%

[halcyon mica]

Here's a question, is it even possible to make a entity pathfind with ladders

[ivory sleet]

Hmm doesn’t spiders do that?

Or well

I guess not ladders

[quaint mantle]

spiders start climbing as soon as they touch one or more blocks on any side

[echo basalt]

write your custom pathfinder

[halcyon mica]

Spiders can climb any surface

Pathfinding is unable to mark certain blocks as climbable

Which would need to be necessairy to pathfind accordingly

Since block node definitions are a enum

Spiders just straight up keep going foward when targeting a position above them

But a climbable pathfinder would need to actively look for nodes marked as climbable

But that is not possible, because nodes cannot be marked as climbable

[solar sable]

how to fix?

[hollow haven]

Hello, I try to load custom blocks from a json and when the plugin load it send an error
The logs: https://hastebin.de/sisaworibe.log
The function: https://hastebin.de/ajugozulaf.java

[sick portal]

Hey everyone, how do you handle players count in a multi-velocity / multi-bungee env ?

[tardy delta]

how the heck can player.getLocation() be null?

[hasty prawn]

If player is null

[tardy delta]

well i'm there

it started when i was sitting on a horse

[hasty prawn]

Wdym

[tardy delta]

well maybe then my location changes i dunno

from that point i requested my location

lemme just restart the server

[ivory sleet]

@quaint mantle

[quaint mantle]

so

[ivory sleet]

create a thread

btw

😄

[quaint mantle]

ok

[ember crag]

https://prnt.sc/1tu9g7a
hey so im making a plugin which lets you sit on stairs using armor stands, and when i spawn the armor stand and let the player ride it, the legs render off to the side rather than straight down the middle like i want, how do i fix this?

is this a minecraft bug or something to do with the way i set up the entity to ride the armor stand?

[solar sable]

bump

guys how to use json text format in plugin?

[tardy delta]

gson?

[vernal pier]

Text components u talking about ?

[quaint mantle]

adventure api

[eternal oxide]

https://www.spigotmc.org/wiki/the-chat-component-api/

[quaint mantle]

I'd personally recommend the adventure api over the bungeecord components ^

[eternal oxide]

This is Spigot not Paper

[quaint mantle]

adventure works on spigot too

[eternal oxide]

Its not in Spigot though. So recommending it (a competing product) is not appropriate.

[quaint mantle]

you can shade it into your plugin ¯_(ツ)_/¯

[solar sable]

i mean paper is just basically spigot, but runs smoother

[eternal oxide]

This is spigot though. He asked in a spigot discord about json in chat so I recommend the spigot chat API.

[solar sable]

paper is literally nothing but just to make the server run smooth lol

[solar sable]

i already figured it out lol

[quaint mantle]

plus extra API

[quaint mantle]

adventure works on spigot ;)

[opal juniper]

shill

whilst paper has some cool api additions and speed increases, please refrain from talking about paper(or any of its sub-apis) in spigot

yours truely

oli

lol

[quaint mantle]

it's not "sub api" 🙃

[opal juniper]

meh im gonna call it that

its made by the same people

[quaint mantle]

eh

[opal juniper]

i was expecting a longer message lol

[tardy delta]

isnt it possible to call the super-super class sonstructor?

[opal juniper]

mmm idk

probably not

[tardy delta]

it doesnt work

sadly

[quaint mantle]

was going to say something about how the kyori team isn't exclusively made up of people in the paper team

[opal juniper]

I mean that is a fair point

but im seeing some uncanny similarities lmao

[quaint mantle]

how to use IChatBaseComponent in 1_16_R3 ?

in 1.17.1 was IChatBaseComponent.a(String)

but there is no method in 1.16.5

[tardy delta]

does anyone knows when static {} is called?

[tall dragon]

when the class is loaded by JVM

[solar sable]

do anyone know how to do a hover event on onPlayerJoin event?

[quaint mantle]

is that the append method?

[tardy delta]

oh

[solar sable]

like player.sendMessage("Test") but with a hover event?

[quaint mantle]

this thing

[tardy delta]

something like this but not with show command

[quaint mantle]

You probably have to cancel the event and broadcast the component if you're using the spigot api

[solar sable]

aah okay

[tardy delta]

anyways whats the best way to make a countdown timer that says something every minute and when it reaches 1 minute it says somethginh every 10 sec?

[solar sable]

maybe

scheduler?

[tardy delta]

yea that

[solar sable]

oh

[eternal oxide]

?scheduling

[undone axle]

https://www.spigotmc.org/wiki/scheduler-programming/

[solar sable]

then use scheduler

theres a specific command to start and stop a countdown

lemme give it to you

ah wait my net is bad rn

[trail flume]

Is there a way to stop Spigot deleting empty config paths?

[quaint mantle]

so in 1_17_R1 the IChatBaseComponent was easy. a simple IChatBaseComponent.a(String)
but there is no such method in 1_16_R3. what should i do ?

[glass sparrow]

Has anyone ever used Jython inside a Java program? If you have please let me know

[vague oracle]

new ChatMessage(chatMessage) ?

[paper viper]

Yes

However, you cant actually really run like a whole actual python program really inside. It's like the python interpreterer

like the terminal python thing you get

you can call python functions however from your java code

[glass sparrow]

Yeah, I was wondering how to compile a python function and then run it later in my java code

[glass sparrow]

I'm trying to use it as a mini scripting method

[quaint mantle]

thanks

[vague oracle]

[hollow haven]

Saving custom block to a json

[quaint mantle]

public static HashMap<Player, List<Integer>> hololist = new HashMap<>(); 

will this work if i get the list, modify it and set it ?

[young knoll]

You don't need to set it

[quaint mantle]

for example i want to add an id to the list of integer

so could i get the integer list

add for example 6 to it

and set it ?

[young knoll]

You don't even need to set it

[quaint mantle]

so what

[young knoll]

Just get the list and modify it

[gritty urchin]

What is the maximum amount of block updates I can send to a client a second

[eternal oxide]

depends on many factors. Their PC horse power, your server horse power, the bandwidth of your connection

There is no way to put an actual number on it

[gritty urchin]

So would 20 - 30 block updates be possible for one block position?

[hollow bluff]

I'm currently having an issue with my plugin. When I start up the server for the first time, some stuff don't work but when I do /rl, it all works fine, why would that even happen?

[gritty urchin]

If sent async

[gritty urchin]

What stuff doesn't work

What is the plugin

[hollow bluff]

?paste

[undone axle]

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

[hollow bluff]

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

That's the error that comes for when I start the server for the first time, but it all works fine after /rl?

[eternal oxide]

WorldLocationUtility.java:166

[hollow bluff]

Location loc = (Location) arenaConfiguration.getArenaConfig().get(getSelected() + ".traitorTester.testerSpawn");```

[eternal oxide]

one of those is null

[hollow bluff]

But why would it work fine after /rl and not other?

[eternal oxide]

arenaConfiguration or getArenaConfig() or there is no entry in that config for getSelected() + ".traitorTester.testerSpawn"

you initialize it at some point

what is getSelected()?

[hollow bluff]

the getSelected() thing is used in a method that is in the enable thing

[eternal oxide]

lots of things, tells me nothing

[hollow bluff]

gameHandler.IN_LOBBY(); is used in the enable, java public void IN_LOBBY() { StateUtility.setState(StateUtility.IN_LOBBY); new Thread(new EnoughPlayersHandler(this, playerHandler)).start(); worldLocationUtility.run(); } this one is what it is

and run selectes one world from the arenalist in the worldLocationUtility.run()

and then it loads it with java private void load() { String world = arenaConfiguration.getArenaConfig().getConfigurationSection(getSelected()).getString("worldName"); Bukkit.unloadWorld(world, false); Bukkit.createWorld(WorldCreator.name(world)); }

all that is done in the enable basically

[eternal oxide]

yeah none of that tells me specifically what getSelected() does

[hollow bluff]

public String getSelected() {
        String result = "";
        return result = String.join("", selectedMap);
    }```

[eternal oxide]

ok

[hollow bluff]

like everything does work after /rl but not when first started

doesnt really make sense to me

[eternal oxide]

what is selectedMap?

[hollow bluff]

public List<String> selectedMap = new ArrayList<>();

[eternal oxide]

k

can eliminate that as null then

The simplest way to to add some sysouts to see what is null

sysout "arenaConfiguration: " + arenaConfiguration == null

etc

do it for each element of that line, to see what precisely is null

[hollow bluff]

I would imagine this is the issue https://paste.md-5.net/unazifudac.sql

not sure how to fix that tho

[eternal oxide]

that means the world is not yet loaded

[quaint mantle]

can we edit an entity by the id ?

for example EntityArmorStand

[opal juniper]

I meean you can use the UUID

World#getEntity(UUID) iirc

[quaint mantle]

i done it with packets

[opal juniper]

oh

[quaint mantle]

nms

modify

an existing entity

[opal juniper]

Modify what

[quaint mantle]

for example updating it's display name

armorstand

[hollow bluff]

it should load with this tho? java private void load() { String world = arenaConfiguration.getArenaConfig().getConfigurationSection(getSelected()).getString("worldName"); Bukkit.unloadWorld(world, false); Bukkit.createWorld(WorldCreator.name(world)); }

[eternal oxide]

it takes time for a world to load

its not instant

[quaint mantle]

i have the id of the armorstand, should i send the meta data again ?

[pallid tiger]

Hi, have a small problem :/ So, maven cannot resolve spigot dependency for 1.17.1, any thoughts?

[hollow bluff]

its 1.17 I think

[eternal oxide]

spigot or spigot-api?

[pallid tiger]

spigot-api

[eternal oxide]

show your pom

?paste

[undone axle]

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

[pallid tiger]

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

[eternal oxide]

looks fine, other than your source/target

1.7?

[opal juniper]

bit weird

old

[pallid tiger]

lemme check

[opal juniper]

and random

[eternal oxide]

InteliJ or eclipse?

[pallid tiger]

vscode

[eternal oxide]

ah

good luck

[pallid tiger]

hah, thanks ❤️

[eternal oxide]

However, nothing wrong with your pom. Can't help you with vs though

[pallid tiger]

np

[quaint mantle]

I'd recommend using a proper IDE like IntellIJ or Eclipse

[quaint mantle]

i also would like to say that IntelliJ is superior for features, customization and syntax highlighting

but eclipse is faster if you care

[dire marsh]

so on 1.17 you can get a "this server requires a custom resourcepack" screen from the normal "recommends" if you set that in the server.properties. How can I achieve this via spigot API? Doesn't seem to be any new setResourcePack methods.

[shadow pulsar]

What to Use Instead of Static

[young knoll]

What about this one? https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/Player.html#setResourcePack(java.lang.String)

[dire marsh]

that just sets the url

and brings up the "recommends" screen

[young knoll]

Correct

You can’t force them to accept it

[dire marsh]

you can tho

if you monitor the resourcepack status event

I want to show this from the API

[young knoll]

Not sure if you can do that without setting the option in server.properties

[dire marsh]

sad

[quaint mantle]

Paper has API for this

[dire marsh]

kekw

[quaint mantle]

Pretty sure you can't do it with API in Spigot

[dire marsh]

paper strikes again

guess I'll have to add a paper check and only enable it on paper servers (otherwise fallback to spigot api)

[grand bronze]

I'm really having trouble creating 3 nested loops over X,Y, and Z any tips?

[dire marsh]

you trying to get blocks in a radius?

[grand bronze]

yes

[quaint mantle]

Why doesn't this work?

// If the entity isn't a allowed entity, cancel event!
        boolean isAllowedEntity = false;

        for (EntityType allowedEntities : pokeballMain.getConfigHandler().AllowedEntities) {
            if (entity.getType() == allowedEntities) {
                System.out.println("&aEntity Type: " + entity.getType() + "&e, AllowedEntity: " + allowedEntities + "&4, Result: true");
                isAllowedEntity = true;
                break;
            } else {
                System.out.println("&aEntity Type: " + entity.getType() + "&e, AllowedEntity: " + allowedEntities + "&4, Result: false");

            }
        }

        System.out.println("result:" +isAllowedEntity);
        if (isAllowedEntity == false) {
            System.out.println("1");
            return;
        } else {
            System.out.println("2");
        }

Config:

AllowedEntities:
  - COW
  - ZOMBIE

Debug:

&aEntity Type: COW&e, AllowedEntity: COW&4, Result: true
[22:05:30] [Server thread/INFO]: result:true
[22:05:30] [Server thread/INFO]: 2
[22:05:30] [Server thread/INFO]: 3

[grand bronze]

trying to make neighboring blocks do the same thing as the first block

[quaint mantle]

should be pokeballMain.getConfigHandler().AllowedEntities.contains(entity.getType())

also should be allowedEntities according to naming conventions

also should be a getter

[dire marsh]

@grand bronze for (double x = start.getX() - radius; x <= start.getX() + radius; x++) { for (double y = start.getY() - radius; y <= start.getY() + radius; y++) { for (double z = start.getZ() - radius; z <= start.getZ() + radius; z++) { // do whatever, get location etc } } }

[grand bronze]

Okay i'll read over this and see if I can make any sense of it I'm very new to java and coding in general so I'm really just here to learn

thank you

[quaint mantle]

add +

between the ChatColors

[opal juniper]

ChatColor1 + "" + ChatColor2

[quaint mantle]

Or you could you do ChatColor.translateAlternateColorCodes('&', "Message")

[opal juniper]

ITs this

you need to add a whitespace

[digital kettle]

i suggest you to use translateAlternateColorCodes or §

"§cHello"

[opal juniper]

NOOOO

DONT USE THIS

[quaint mantle]

I have this code now, but it doesn't stop the code in the !isAllowedEntity

boolean isAllowedEntity = pokeballMain.getConfigHandler().AllowedEntities.contains(entity.getType());

        System.out.println("result:" +isAllowedEntity);
        if (!isAllowedEntity) {
            System.out.println("Stop");
            return;
        } else {
            System.out.println("pass");
        }

[hasty prawn]

Definitely use translateAlternateColorCodes

[young knoll]

I mean you should be using the enum constants

[hasty prawn]

I'd use them if they weren't so terrible to work with

[quaint mantle]

or proper chat components ¯_(ツ)_/¯

in plugin.yml, add aliases: [ youraliashere ] to the command

Add a aliases: [aliasCommand] to the command in plugin.yml

[robust jolt]

Hello, how i can check if block placed is a tnt?

I use this event: BlockMultiPlaceEvent

[young knoll]

BlockPlaceEvent

[formal dome]

hey guys, what is a commandsender?

[young knoll]

A sender of a command

[glossy barn]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/block/BlockPlaceEvent.html#getBlockPlaced()

Since MultiBlockPlaceEvent inherits from BlockPlaceEvent, you can call getBlockPlaced() without having to modify your existing code

[young knoll]

I don't think the multiplace event will fire for tnt

[robust jolt]

how i can check if block is tnt?

[young knoll]

Get the material and compare it to Material.TNT

[formal dome]

when does BroadcastMessageEvent trigger?

nvm nvm

i'm not dumb i can read docs xD

[quaint mantle]

Hey. In mysql, if I try to update a value in a row but if the value in that row is equal to the value I've write in the query, will it still be updated? I mean, will the method executeUpdate() return 0 or 1?

[carmine nacelle]

How would I use one of my plugins as a dependency for another? like.. I need to be able to get methods from the dependency inside the dependent plugin

[burnt rapids]

How can I get text input from a player using the edit message sign gui (also how can I show the sign gui to the player)

[unreal quartz]

i believe it checks so the changed count should return 0

[quaint mantle]

Ty

[unreal quartz]

mysql docs https://dev.mysql.com/doc/refman/8.0/en/update.html

If you set a column to the value it currently has, MySQL notices this and does not update it.

[quaint mantle]

Thanks man, I ly ❤️

[carmine nacelle]

Would I need to make all of my methods static in my dependency plugin?

[ivory sleet]

No dont do that

[carmine nacelle]

alright...well

it's telling me it can't resolve a method from it

not sure why.

    private boolean setupHoloPlugin() {
        if(getServer().getPluginManager().getPlugin("CadiaHolos") == null) {
            return false;
        }

        cadiaHolos = (CadiaHolos) getServer().getPluginManager().getPlugin("CadiaHolos");

        return false;
    }

Got this in the main class of my 2nd plugin, registering the instance of the main one

and trying to get the methods from it

cadiaCore.cadiaHolos.setupHolo(player, hologram);

[unreal quartz]

not.. entirely sure what you're trying to do?

[carmine nacelle]

I need to use Plugin A as a dependency for plugin B

and be able to get the methods from A in B

[unreal quartz]

okay, well if your dependency is called CadiaHolos then you're good to access its methods in the above method since you assigned an instance of it to cadiaHolos

in other words cadiaHolos.XXXXXX will work

[carmine nacelle]

right thats what I was thinking but

If I add a new method to plugin A, how would I refresh project B so it'll show up?

(intellij)

[unreal quartz]

compile it and add that as a dependency

[carmine nacelle]

Yeah, it already is one

do I gotta remove and readd?

using it as a jar dependency right now

[unreal quartz]

if you've used the exact name then yes, intellij will need to rebuild its indexes of it

otherwise it doesn't know it has changed

[sullen marlin]

lame

[carmine nacelle]

So, I'm using the CadiaHolos as just a way to display the information, then I want to be able to use it in 2 separate plugins so I plan on adding the interact methods for each dependent plugin inside the dependent plugin itself.

Good idea or naw

then I plan on saving the holograms in files for each plugin, so they would be saved in plugin B's folder instead of plugin A's

idk if thats a smart move or not.

[grand bronze]

how would I specify what blocks I want to affect within a loop

[quaint mantle]

add them to an enumset

[grand bronze]

alright time to figure out what the fuck that is

[quaint mantle]

Set<Material> allowBlocks = EnumSet.of(Material$1, Material$2...);

for (...) {
    if (!allowBlocks.contains(block.getType()) {
        continue;
    }
    // ...
}

[formal dome]

when creating a new event what should i think about when trying to define my set of <CommandSender>'s

[quaint mantle]

?

[ivory sleet]

Why CommandSender

[formal dome]

i think i got my thought process wrong.

let me try to explain

i was initially going to create a new broadcastmessagevent that triggers when a broadcast message is sent

[ivory sleet]

😬

[formal dome]

so i could have my discord bot listen for that event and post a message in discord when it comes.

but, i figured there has to be a current broadcastmessage event already in existence that the server throws

is there a way to access that?

[ivory sleet]

Idk

Only if an event callback fails Ig?

But then you’d be prompted with a stacktrace

[formal dome]

hmmm

time to dive deeper into the docs

[ivory sleet]

Anyways

If you just wanna send a message to every player online

Don’t use broadcastMessage lol

[formal dome]

nah that's not my goal

my goal is to take broadcasted messages and post them to my discord channel for my server

[ivory sleet]

Oh

Well in that case

Then just listen for the event and send to the discord message channel?

[formal dome]

precisley! i just think i'm struggling with understanding the exact syntax of that. i'm using the jda-java api for discord and i've registered a generic eventlistener.

[ivory sleet]

Why

[formal dome]

i don't know how to connect the event to the eventlistener

[ivory sleet]

You don’t need any jda event listeners if your only goal is to send a message to a channel with JDA

[lost matrix]

You dont want a jda listener. You want a bukkit listener. The bot itself just sends messages in a channel.

[ivory sleet]

^

[formal dome]

.ohhh

yeah that makes sense i think

[hollow bluff]

I can get org.bukkit.block.Chest in 1.8.8 but I cant get org.bukkit.block.EnderChest?

How may I get the clicked block?

[lost matrix]

1.8 support was dropped almost half a decade ago. It has a bunch of bugs that will never get fixed and lacks a ton of API features.
You should move on.

[hollow bluff]

nah

1.8 is kinda better tbh

for what I need

[lost matrix]

Well... then you have to live with the handicaps an very outdated piece of software comes with 🤷

[hollow bluff]

figured it out, I can just do this and it worked java if (event.getClickedBlock().getType().equals(Material.ENDER_CHEST)) {

Do anyone know how to make redstone lamps stay on?

[young knoll]

Use == for enums

[grand bronze]

this enum shit got me re-thinking my life

[trail remnant]

does anyone know how to set someone balance with the vault api?

[lost matrix]

Check how much the player has and then add/subtract the delta.

[austere bone]

hey! might be a simple question, but, how do you create a repeated task to run every hour?

[trail remnant]

but i want to set it, not add it

[lost matrix]

Right. Then check how much a player currently has and add/subtract the delta

[lost matrix]

There are several ways of approaching this. How precise do you need this to be?

[trail remnant]

sorry, i dont know how i would do that 😅 is there a documentation or something?

[lost matrix]

http://milkbowl.github.io/VaultAPI/

[austere bone]

as precise as can be

[lost matrix]

So a binary interpolation polling approach

[trail remnant]

i dont see any way to set a balance on there though?

[lost matrix]

Yeah. You need to get the current balance and then add/subtract the delta. As stated before.

[lost matrix]

Ill show you a quick example

[trail remnant]

yes i know, but then i said i dont know how id do that so is there a documentation or something?

i know how to get the balance but not the delta thing

[austere bone]

thank youu!

[lost matrix]

So you want to basically half the time interval every poll until you reached the atomos of your timestep.

[austere bone]

ahhh okk tyy

[lost matrix]

Btw you can also use an external library called Quartz to schedule tasks at specific points in time.

Example:

Trigger trigger = TriggerBuilder.newTrigger()
  .withIdentity("myTrigger", "group1")
  .startNow()
  .withSchedule(SimpleScheduleBuilder.simpleSchedule()
    .withIntervalInSeconds(40)
    .repeatForever())
  .build();

[lost matrix]

You should def use a Map<String, Arena> here

[native nexus]

I did before but changed it

ill revert it back

It is because I wanted to have the name inside the arena class

[lost matrix]

Arena.class

[lost matrix]

You can still do that

But also use it as a key mapping

[native nexus]

Yeah

[lost matrix]

Nice to see proper manager classes for once

[native nexus]

public class ArenaManager {

    private Map<String, Arena> arenas = new HashMap<>();

    public Arena getArena(Player player) {
        return arenas.values().stream().filter(arena -> arena.getPlayers().contains(player.getUniqueId())).findFirst().orElse(null);
    }

    public Arena getArena(String name) {
        return arenas.get(name);
    }

    public boolean remove(Player player) {
        Arena arena = getArena(player);
        if(arena != null) {
            arena.remove(player);
            return true;
        }
        return false;
    }

    public void add(String name, Arena arena) {
        arenas.put(name, arena);
    }

    public void remove(String name) {
        arenas.remove(name);
    }

    public boolean add(Arena arena, Player player) {
        Arena playerArena = getArena(player);
        if(playerArena != null) return false;
        arena.add(player);
        return true;
    }

    public void serialize(Plugin plugin) {
        Json.write(plugin, "arenas", arenas);
    }

    public void deserialize(Plugin plugin) {
        arenas = Json.read(plugin, "arenas", new TypeToken<Map<UUID, Arena>>(){}.getType());
        if(arenas == null) arenas = new HashMap<>();
    }
}``` Ok literally changing it back to a map fixed it

Does it not support sets?

This is weird

[lost matrix]

It does. Could you pls show your Arena.class or at least the fields

[native nexus]

private transient final Set<UUID> players = new HashSet<>();
private final String name;
private ArenaState state;
private Point one, two;
private int minPlayers, maxPlayers;

I don't want it to store a set of players (uuids)

[lost matrix]

Ok looks fine. I just suspected that you have a non transient ArenaManager class in there which would cause a StackOverflow

[native nexus]

Oh haha no way

Changing it from a Set to a Map fixed it

Really bizarre...

[lost matrix]

Ok nice. Btw take a second look at your TypeToken

[native nexus]

Yes (UUID)

Should be name 😛

(string)

Thank you!

Actually I am getting the same error again hmm

[lost matrix]

Eh... how does the full stack trace look like?

[native nexus]

Wait no this is a new error

This is in the SpleefManager class

[lost matrix]

Btw you could try and serialize/deserialize the whole ArenaManager without a TypeToken for the map. Let gson do the hard lifting.
Json.write(plugin, "arenas", this);
and
this.arenas = Json.read(plugin, "arenas", ArenaManager.class).arenas;

[native nexus]

Didn't think of that

lobby = Json.read(plugin, "lobby", Location.class); Let me guess I can't serialize a bukkit location

[lost matrix]

It holds a reference to a World i think.

[native nexus]

Yeah it does

Are references transient?

It doesn't look like it.

[lost matrix]

Not sure how Gson handles this

[native nexus]

I might have to create my own encapsulation class...

[lost matrix]

Or just write a custom Serializer and register it with Gson

[native nexus]

I haven't written one before any documentation on that?

[lost matrix]

One moment ill give you an example

public class LocationSerializer implements JsonSerializer<Location>, JsonDeserializer<Location> {

  @Override
  public Location deserialize(
      final JsonElement jsonElement,
      final Type type,
      final JsonDeserializationContext jsonDeserializationContext
  ) throws JsonParseException {
    
    final JsonObject jsonObject = jsonElement.getAsJsonObject();
    final double x = jsonObject.get("x").getAsDouble();
    final double y = jsonObject.get("y").getAsDouble();
    final double z = jsonObject.get("z").getAsDouble();
    final float pitch = jsonObject.get("pitch").getAsFloat();
    final float yaw = jsonObject.get("yaw").getAsFloat();
    final UUID worldID = UUID.fromString(jsonObject.get("world").getAsString());
    final World world = Bukkit.getWorld(worldID);

    return world == null ? null : new Location(world, x, y, z, pitch, yaw);
  }

  @Override
  public JsonElement serialize(
      final Location location,
      final Type type,
      final JsonSerializationContext jsonSerializationContext
  ) {
    
    final JsonObject jsonObject = new JsonObject();
    jsonObject.addProperty("x", location.getX());
    jsonObject.addProperty("y", location.getY());
    jsonObject.addProperty("z", location.getZ());
    jsonObject.addProperty("pitch", location.getPitch());
    jsonObject.addProperty("yaw", location.getYaw());
    jsonObject.addProperty("world", location.getWorld().getUID().toString());

    return jsonObject;
  }

}

Then later for registration:

    final Gson gson = new GsonBuilder()
        .disableHtmlEscaping()
        .setPrettyPrinting()
        .registerTypeAdapter(Location.class, new LocationSerializer())
        .create();

[golden turret]

use the service manager from bukkit

json

[native nexus]

Awesome thank you do much!

Good to see that you are using UUID instead of name

I hardly ever use final keywords like that. Is it a good practice to do so?

[worldly ingot]

When local scoped, it's preference. I never do it personally because I dislike the look of it, but if you're concerned about ever reassigning your variables when you don't expect to, you can do it. It's unlike C++ where you can declare your parameters are constant

[formal dome]

how do i register a plugin with spigot?

oops

i mean eventlistener

[lost matrix]

Its preference. I always set my IDE up so that it uses them in a bountiful manner.
It makes every variable thread safe by default, qualifies them for usage in lambdas and makes the intention clear that they should not be changed.
Some think its a bit cluttering but i personally prefer it this way.

[formal dome]

with the current instance of spigot

or would it be an instance of bukkit

[native nexus]

Alright thank you for the feedback!

[golden turret]

using variables in lambda: AtomicReference

or something with a name like this that i forgot

[lost matrix]

You need an instance of your JavaPlugin class and the PluginManager.
Step by step:

    JavaPlugin plugin = ...;
    Listener yourListener = new YourListener();
    PluginManager pluginManager = Bukkit.getPluginManager();
    pluginManager.registerEvents(yourListener, plugin);

Often used like this:

  @Override
  public void onEnable() {
    Bukkit.getPluginManager().registerEvents(new SomeListener(), this);
  }

[formal dome]

oh

okay

was about to say do i need to create an instance of my plugin within the plugin

[lost matrix]

Nope. This will cause an Exception to be thrown.

You get one single instance of your JavaPlugin class and you need to distribute it to the places which need it.

Is something wrong with this query?

INSERT INTO acash (name, cash) VALUES (?, ?) ON CONFLICT(name) DO UPDATE SET cash=?

I'm getting this error:

[01:17:35 WARN]: java.sql.SQLException: [SQLITE_ERROR] SQL error or missing database (near "ON": syntax error)

[native nexus]

I tried this but it seems to throw an exception. Might just use TypeToken

[golden turret]

sqlite does not have this

[quaint mantle]

Oh 😦

Is there another way to do it?

[golden turret]

until you get a real solution, try REPLACE INTO

[worldly ingot]

Or ON DUPLICATE KEY if your name is a unique key

[quaint mantle]

It's

I'll try both

Ty

[golden turret]

replace into is not performatic

but works

[lost matrix]

Google SQL Upsert. There are many patterns explained.

[quaint mantle]

I did

Tried ignore and on conflict

[golden turret]

but

you want to update their cash, right?

[quaint mantle]

I want to do upsert

Insert if not exists

[golden turret]

ok

[quaint mantle]

If it does update it

[golden turret]

got it

i personally use a simple system

where i call the methods

[quaint mantle]

2 statements, right?

[golden turret]

isDirty isDeleted and isInDatabase

and their respective setters

when i load a user from the database

i mark the user as inDatabase

and not dirty

so when i want to update them

i check if they are dirty and if in database

[lost matrix]

I just let Gson create some Json data and then throw it into mongodb. Since i moved to document based DBs im actually not sure why SQL
is so popular with the spigot community. At the very least i would want to heavily abstract away all those String queries by using something
like QueryDSL.

[golden turret]

if (!isDirty() && isInDatabase())
  return; //nothing happened

setDirty(false); //they will be clean after that
if (isInDatabase()) {
  //update in the database
  return;
}

//insert into the database
setInDatabase(true); //in database now :D```

[lost matrix]

This sounds like you do a bunch of queries which are not necessary. (If isInDatabase() queries the DB for example)

[golden turret]

no

i will send you an example

[quaint mantle]

I want to do it in one statement

[golden turret]

ok

and you will

only 1 of the 3 queries will be used

[lost matrix]

Ah i see what you mean

Yeah that looks fine. Can also help with batching.

[golden turret]

i think that it is beautiful :3

[lost matrix]

Btw you should check this out:

[formal dome]

@lost matrix so now that i have my event listener registered. where do i put my code to handle that event?

[native nexus]

try {

    commandMapField.setAccessible(true);

    CommandMap commandMap = (CommandMap) commandMapField.get(server);
    commandMap.register(getName(), this);

} catch (NoSuchFieldException | IllegalAccessException e) {
    e.printStackTrace();
}
``` For those who can't be ***ed adding commands to the plugin.yml

[lost matrix]

https://www.spigotmc.org/wiki/using-the-event-api/

[golden turret]

i personally like to add the commands in the plugin.yml

[lost matrix]

Or just use an established command framework like ACF

[worldly ingot]

Not to mention plugin command attribution

[native nexus]

I don't like ACF that much

[golden turret]

just an addition

i never heard about acf

i use the command system of wlib 😎

[native nexus]

Eh annotations...

[lost matrix]

Its not everyones cup of tea. It took me forever to learn every little feature and now
i dont feel like switching to anything else.

[native nexus]

I just use my own command class.

[golden turret]

or

CommandExecutor

[native nexus]

public abstract class CommandBase extends Command implements Registry {

    protected CommandBase(String name, String... aliases) {
        super(name);
        setAliases(Arrays.asList(aliases));
        setPermission("command." + getName());
    }

    @Override
    public boolean execute(@NotNull CommandSender commandSender, String s, String[] strings) {
        if (commandSender instanceof Player player) {
            if (!player.hasPermission(Objects.requireNonNull(getPermission()))) {
                player.sendMessage("You do not seem to have permissions.");
                return true;
            }

            return run(player, strings);
        }
        return false;
    }

    public abstract boolean run(Player player, String[] strings);

        } catch (NoSuchFieldException | IllegalAccessException e) {
            e.printStackTrace();
        }
    }
}
``` I use string arrays for arguments but put them in different functions like ACF has the subcommand methods

[quaint mantle]

níhao, wondering how to de-obfusicate classes such as net.minecraft.server, org.craftbukkit, etc.

[quaint mantle]

💀

[lost matrix]

I just like having full control over aliases, completions, context resolvers, permissions etc in just a few lines of code:

@CommandPermission("admin")
@CommandAlias("weapons")
public class WeaponCommand extends BaseCommand {

  @HelpCommand
  public void onDefault(final CommandSender sender) {
    Msg.sendInfo(sender, "/weapons melee <Type>");
    Msg.sendInfo(sender, "/weapons ranged <Type>");
  }

  @Subcommand("melee")
  @CommandCompletion("@MeleeWeapon")
  public void onMelee(final Player player, @Values("@MeleeWeapon") final MeleeWeapon weapon) {
    player.getInventory().addItem(weapon.getItem());
    Msg.sendInfo(player, "Du hast {} erhalten.", weapon);
  }

  @Subcommand("ranged")
  @CommandCompletion("@RangedWeapon")
  public void onRanged(final Player player, @Values("@RangedWeapon") final RangedWeapon weapon) {
    player.getInventory().addItem(weapon.getItem());
    Msg.sendInfo(player, "Du hast {} erhalten.", weapon);
  }

}

[golden turret]

wlib:

@Command(execution = "command <hello> [world]")
public void command(Player player, String hello, String[] world) {
  player.sendMessage(hello);
  if (world != null)
    player.sendMessage(world);
}

//onEnable
new CommandManager(plugin).registerCommands(commandClass);```

[native nexus]

The command completion/context resolvers is quite nice.

[lost matrix]

You can use mojang mappings. You can read about it here:
https://www.spigotmc.org/threads/spigot-bungeecord-1-17-1-17-1.510208/

[paper viper]

I prefer builders over annotations xD

like each class is like a subcommand and stuff

doesn't matter tho

[native nexus]

Me too!

[grand bronze]

  for (double x = start.getX() - 5; x <= start.getX() + 10; x++)

how would I actually set a radius with this

[lost matrix]

First of all: Dont use doubles for that.

[grand bronze]

int?

[paper viper]

doubles in a loop 🤡

[grand bronze]

😦

I'm new I apologize

[lost matrix]

Example:

  public List<Block> getBlocksAround(final Block center, final int radius) {
    final List<Block> blockList = new ArrayList<>();

    for (int x = -radius; x <= radius; x++) {
      for (int y = -radius; y <= radius; y++) {
        for (int z = -radius; z <= radius; z++) {
          blockList.add(center.getRelative(x, y, z));
        }
      }
    }

    return blockList;
  }

[formal dome]

@lost matrix does my plugin have to implement listener or do i have to implement listener in a separate class

[lost matrix]

Btw just for fun. This does the same thing:

  public List<Block> getBlocksAround(final Block center, final int radius) {
    return IntStream.rangeClosed(-radius, radius)
        .mapToObj(x -> IntStream.rangeClosed(-radius, radius)
            .mapToObj(y -> IntStream.rangeClosed(-radius, radius)
                .mapToObj(z -> center.getRelative(x, y, z))))
        .flatMap(Function.identity())
        .flatMap(Function.identity())
        .collect(Collectors.toList());
  }

[native nexus]

You implement listener in the same class as where you have your eventhandler method

[paper viper]

let me copy that

xD

[young knoll]

That is horrible

[lost matrix]

Yes. And it performs like that too.

[paper viper]

i just realized there are two .flatMap calls lmao

[lost matrix]

Yeah because i first have a stream of stream of streams of blocks that need to be mapped to a stream of stream of blocks which then needs to be mapped to a stream of blocks

[paper viper]

seems super inefficient kek

[lost matrix]

But its technically a one liner. 😄 which is much more important than performance.

[golden turret]

yes!

[golden turret]

@Override public void onEnable() { getLooger.info("Hello!"); Bukkit.getPluginManager().registerEvents(this, this); }```

any idea for how to auto scaling backend spigot servers for balancing available maps?

I don‘t want to use docker or anykind of containerd for latency/performance issue. (if you have any resources for using kubernetes without containerizing it, please tell me.)

[pastel stag]

anyone familiar with mysql and can clue me into what command i would have to use to attach a rowid to each new row into a database table ive got

prepareStatement("INSERT INTO wb_blocks" + "(NAME,UUID,WORLD,X,Y,Z) VALUES(?,?,?,?,?,?)");

and i would like to have something like

where ROWID is just whatever row number that new data will be on and it just counts upwards by itself never repeating as new data is entered

[quaint mantle]

getLooger

[pastel stag]

@quaint mantle instructions unclear, dick stuck in blender

[quaint mantle]

please turn on blender for maximum enjoymen. :)

[pastel stag]

i know it has something to do with @row_number but not sure how to implement it tbh if i have to set the variable when the table is created or what

[quaint mantle]

use insert or set row id to x
or use hashtables and create table named rowid and index it from there.

[pastel stag]

im using insert already to put new data into the table, but idk how to add in a 'counting' rowid that increases by 1 automatically w/ every new entry if that makes sense

[quaint mantle]

idk or you can use mongoDB, hypixel uses mongoDB.

[quaint mantle]

what are you tring to do?

[pastel stag]

have you ever seen how coreprotect numbers their block data with a row id?

[quaint mantle]

LMAO i give up

[pastel stag]

like so

[quaint mantle]

im new

[pastel stag]

https://gyazo.com/426329c56bdfec576236653996138056

[quaint mantle]

i dont know

[pastel stag]

im basically trying to do the rowid part of that

[quaint mantle]

um the row id seems to be working alright

[pastel stag]

the rowid that i linked, i'm trying to accomplish that w/ my own plugin

it just counts, idk if that makes sense lol

[quaint mantle]

before adding row to database, get last lowID. add 1 and insert to DB.

rowid counting?

[pastel stag]

yeah thats basically wht im needing to do

get the last rowid add 1 to it and insert that number into the preparedstatement w/ the rest of my command i just dont know what sql query commands do that stuff lol

[quaint mantle]

lol we are all new

LOL

goodbye

[young knoll]

You can set your ID to auto increment

[formal dome]

alright. so how close is this to sending my desired message to my discord channel

public class broadcastReader extends JavaPlugin implements Listener {

    public JDA jda;
    public BroadcastMessageEvent onMessageBroadcast;

    @Override
    public void onEnable() {

    @EventHandler
    public void onMessageBroadcast (BroadcastMessageEvent event) {

        jda.getGuildById("758813062848708670").getTextChannelById("758813063448363011").sendMessage(event.getMessage());

    }
}

[lost matrix]

Containers would be the way to go here.
But you can also just write java code which copies prototype folders and starts new jvm instances.

[lost matrix]

getServer().getPluginManager().registerEvents(new broadcastReader(), this);
to
getServer().getPluginManager().registerEvents(this, this);

You are not allowed to create an instance of JavaPlugin classes.
Also right click -> refactor your class and rename it to BroadcastReader

[lost matrix]

And you def dont want to fetch the guild and channel every time a message is broadcasted. Use fields to store them instead.

[formal dome]

alright before compiling and testing.. i already know i'm gonna have some library shading issues... where can i find the syntax for shading in the libraries in plugin.yml

[lost matrix]

https://www.spigotmc.org/wiki/plugin-yml/

[golden turret]

it could have something like

• url: url
  somethingiforgot: com.examble:example:1.0.0

[quaint mantle]

making it change map based on how many map are available and balance it to x available maps?

[lost matrix]

What do you mean by "map"? I thought you wanted server instance load balancing.

[quaint mantle]

map, server, the same thing.

[ancient plank]

maps and servers are not the same thing but u do u bro

[paper viper]

lol

[quaint mantle]

same point, just balancing for availabilit.

[lost matrix]

The implementation depends on your server model and use case.
Do you need a bunch of smaller servers that host minigames for examples or do you have one
large core which should be instanced but provide effectively the same experience on each instance?

[quaint mantle]

a bunch of big separated machines.

200 8Core backend, 5 proxy

example *

[lost matrix]

Sure but what is your server model?

[quaint mantle]

each server run around 4 to 8 servers.

[lost matrix]

Do you host your servers in the cloud (AWS for example)

[quaint mantle]

bare metal, or so called home host.

[lost matrix]

I dont think bare metal means what you think it means.
Anyways then you dont need dynamic scaling by any means. Kubernetes or not.
You have fixed constraints.

[quaint mantle]

i have fixed hardware, and i want it to balance for available software.

[lost matrix]

Ok then you probably want nginx with a reverse proxy setup that leverages the load
between your bungee proxies using a round robin distribution.

[quaint mantle]

wwwwwWWwwW???????????

im confused

wh

[lost matrix]

One moment

[quaint mantle]

i know what you mean, but is not why i came here for.

i have reverse proxy setup.

[quaint mantle]

two moment…

[quaint mantle]

three moment…

[lost matrix]

In this scenario the bungee proxies have the responsibility of distributing the load between the running mc instances.

Based on the player count.

The Nginx proxy has the responsibility to distribute the connection load between the bungee proxies because one instance can handle ~200 players at once max
(If you do a lot of packet magic then even as low as 150)

[quaint mantle]

ok, you come to hypixel and play bedwars. the server available for bedwars games are 100 servers at 16 per. and skywars have 50 server/16. there are 1600 players playing bedwars while 400 playing skywars, the unused skywars server how wants to change it self to bedwars so more players can join.

balancing players and queue are not the same…

[lost matrix]

Thats why i asked for a server model...

[quaint mantle]

pretty much the same.

[lost matrix]

This above would work for something like Wynncraft

[quaint mantle]

there is a mastercontrol that handles queue, party, /msg…

[spare marsh]

Quick question
So
If I have a YAML File then I save it, will it continue to be loaded after I have saved it or would I have to load it again?

[lost matrix]

Then go for Kubernetes and Containers.

[quaint mantle]

docker or other container have 5% to 15% performance decreas. and adds 20ms of ping to database requests or client.

[lost matrix]

It stays in memory. So as long as you have a reference to your YamlConfiguration it will be kept in memory.

[spare marsh]

Thank you so much, I thought I was gonna get a rude response.

I dont know where you get those numbers from but they are not true. I wrote a whitepaper last year about the performance overhead of docker.
If you are on a Linux machine then there is almost no performance overhead (Unless you are on Windows)

IBM Research Report
https://course.ece.cmu.edu/~ece845/sp18/docs/containers.pdf

and a lot of other resources i found.

[native nexus]

This report is from 2014

[lost matrix]

Yeah i know this paper. Its from 2014 and pretty much proves my point. Docker is even faster than kvms.

[native nexus]

Technology has changed a lot since then

[quaint mantle]

what is your whitepaper’s link?

[lost matrix]

I cant publicly share it because it contains confidential information but i can give you a truncated version.

[quaint mantle]

dm me

First of all this is the repository for the JMH benchmarks:
https://github.com/Flo0/JMHSandbox/tree/master/src/main/java/com/gestankbratwurst/jmhbenchmark

[quaint mantle]

404

[lost matrix]

Should be public now

[quaint mantle]

hmm

.java files?

[native nexus]

clone it and run it

easy peasy

[quaint mantle]

alright

[native nexus]

Also mandelbrot 👀

[lost matrix]

Oh right... its in german. 🤦‍♂️

Anyways the conclusion is that a jvm ran in docker has practically no overhead.
If you use generated native code (GraalVM, Quarkus) then it even outperforms a normally run JVM

[quaint mantle]

:D

[lost matrix]

Yeah i use mandelbrot whenever i learn a new language as its a pretty good measurement for
how well a lang handles nested loops and math in the imaginary number space.
Btw listed from slowest to fastest so far:
Ruby, Python, Lua, JavaScript, C#, Java, Rust, C++, C
If Python uses C libraries for the math then its on par with JavaScript.

[native nexus]

I have done mandelbrot in C++ before with using SDL2

And ooooh interesting!

I remember when I made windows applications with C and I had to write so many switch statements 😆

[lost matrix]

Ah i have yet to write a mandelbrot evaluation which utilizes the GPU.

[native nexus]

Yes I recommend utilizing the GPU omg

[lost matrix]

But i got a curse for KUDA and Shader programming coming up 😍

[native nexus]

My friend and I while we were at university made procedural terrain generation with compute shaders for our game.

Shader Programming is 👉 👌

Open simplex noise?

wait what ?

a it's something with my plugin.yml. b: its something with the way i passed strings to my JDA

[lost matrix]

Show your plugin.yml

[native nexus]

No we did Perlin noise

[formal dome]

main: com.craftinc747.discord.logReader
name: LogReader
version: 1.0.0
libraries:
  -net.dv8tion:JDA:4.3.0_324
  -
database: true```

i didn't actually finish it lol

[lost matrix]

Almost the same 😄

[formal dome]

wasn't sure which libs i needed in there tbh

[native nexus]

Yeah pretty much 😛

[lost matrix]

Anyways im out for now. BB

[native nexus]

Cya

[formal dome]

peace

[carmine nacelle]

im so confused right now..I moved some stuff around in my plugin and now my gui clicks are registering twice. sending two messages, etc.

its not registered twice

[native nexus]

It might be because it is registering left and right click/

There is a fix for that but I can't remember

[carmine nacelle]

I have it checking if its left only, still fires twice

[young knoll]

Have you restarted the server

[carmine nacelle]

it shouldnt fire twice though cause left/right is separate in that

yes

what's super weird is.. the green message sends twice while the yellow only sends once

https://i.gyazo.com/8b4996483f528c48121e9ae4f1725743.png

I would expect both to send twice if that was the issue

oh..

ok im just retarded.
