[fallow hearth]

just increment the ID bei 10_000 or something and check if it spawns

And check if there is a player-entry in the tab-list for that player

[tepid cargo]

Spigot breaks a vanilla mechanic where explosions push invulnerable mobs. Any idea how to fix?

[proud basin]

How could I make this lighter than what it's already ababab hex color

[stiff ember]

How light?

[proud basin]

like a decent amount

I want to still be able to see the white but like not too much

[stiff ember]

Did you try a color picker?

[quaint mantle]

what

[echo basalt]

What is the error?

are you saving it as a .bat file?

yeah

save it as a .bat file

Save as

All files

start.bat

ug

save

and run the file

all files

same thing

[paper viper]

is it private or something?

oh

you need to verify

[echo basalt]

you didn't use the all types option

yea

uh

rename your spigot.jar to just spigot

as you have it as spigot.jar.jar atm

means you got no ram

[quaint mantle]

how much ram do you have installed?

[gaunt hatch]

What was world.setGameRuleValue replaced with?

[quaint mantle]

on your system

[worldly ingot]

Just setGameRule(), Doc

[vague oracle]

world.setGameRule(GameRule.DO_PATROL_SPAWNING, false);

[worldly ingot]

as is noted in the deprecation notice ;p

[gaunt hatch]

Sweet thx

[vague oracle]

try 4

also aren't you meant to have a min value or is that not required?

[gaunt hatch]

Would be cool if when they are deprecated they tell you why and what to use. I guess I am asking for to much.

[eternal oxide]

They do, you just can't read

[worldly ingot]

It does

Literally right there lol

[quaint mantle]

😮

[gaunt hatch]

i mean in code not on the online javadocs

[worldly ingot]

Download the docs

Spigot's done their part, do yours lol

[unreal quartz]

ye u lazy

[eternal oxide]

I can assume you are using Eclipse if you don;t see teh javadocs in your IDE

[gaunt hatch]

Can you import them?

[worldly ingot]

Eclipse shows docs just fine Elgar

[unreal quartz]

click button

[eternal oxide]

Only if you add them.

[paper viper]

if you use intellij you get nice formatting

[gaunt hatch]

This is what i see

I dont use maven

Need to how i can do this i did not know i could import them

[unreal quartz]

it is automatic for gradle

[gaunt hatch]

well i guess not cause what i posted it what i see for that method

[unreal quartz]

google is your friend

[gaunt hatch]

Yup doing that now

[unreal quartz]

might be bc u are using the spigot artifact

[gaunt hatch]

What should i use the spigotapi?

[unreal quartz]

this is from spigot-api (see bottom line)

[gaunt hatch]

yea that looks way better

nope still the same

implementation "org.spigotmc:spigot-api:$MINECRAFT_VERSION-$SPIGOT_API_VERSION-SNAPSHOT"

[unreal quartz]

is there a sources jar in ur dependencies

[gaunt hatch]

yes

[unreal quartz]

just add the documentation manually

[gaunt hatch]

how? is the question

[gaunt hatch]

That i found, but the issue is that file path i have nothing in.

[vague oracle]

you change 6 to 4 and save the file

[young knoll]

Do you have 64bit java

Mhm

[paper viper]

yes

[young knoll]

You can’t see your file extensions

So it’s technically named start.bat.txt

Iirc it’s an option in the view tab

Google can probably help

[quaint mantle]

why you askin me

you're in notepad

its just text

if you open a .java file its just text

code is just txt until its turned into machine code

[quaint mantle]

how do i modify the text of an existing hologram

[paper viper]

do you have any info about the hologram?

like entity uuid?

[quaint mantle]

ArmorStand hologram3 = (ArmorStand)

i think i could edit it inside the if statement but i want hologram3 to be public to all if statements

[young knoll]

Do you have any control over the namespace when you register a command with brigadier, or will it always be minecraft:command

[paper viper]

store the hologram outside the if statement then

or like define the variable at least

if that makes sense

[quaint mantle]

yeah i was thinking of doing that

[paper viper]

then do it

lol

[quaint mantle]

ok but

how do i replace p.getLocation with player cords

[paper viper]

asign p.getLocation to a variable and reasign it?

[prime reef]

wait...can you have custom sounds without replacing any?

I've been under the impression that you can't

[young knoll]

You can

[quaint mantle]

ok it worked :DDD

[quaint mantle]

so i guess im confused

how exactly do i use AttributeModifier to increase health

i know the URLs, i know the GENERIC_MAX_HEALTH

im just wondering like... how?

[quaint mantle]

ykw nvm

[summer scroll]

I'm trying to create a multi-module project with Maven, can someone guide me with it? Right now I have a project but I want to implement a feature with NMS.

[ivory sleet]

I could if it was gradle

[summer scroll]

Ah, is it complicated to switch from Maven to Gradle?

[ivory sleet]

I wouldn’t say

But some assert it is

It’s like 1 command in the cmd line

[summer scroll]

I can try maybe

Let me open up a thread real quick

Converting Maven project to Gradle in IntelliJ

[ivory sleet]

Alright download https://gradle.org/releases

Then put it into the directory
C:\Gradle

Then add an environment variable under Path called, C:\Gradle\gradle-7.2\bin

Assuming u use Windows

Anyways here’s the thread

https://docs.gradle.org/current/userguide/installation.html#installation

Or doc

Once you’ve done that, you can basically open up the IntelliJ terminal and run gradle init

[summer scroll]

Let's move to the thread. #887580251432030228

[ivory sleet]

I mean there aren’t really anything else going on rn

[summer scroll]

For the multi module too

[ivory sleet]

But sure Ig

how to make a livingentity not drop items

cancel the drops in ondeath ? (if it is possible)

[quasi flint]

or just clear em

but yeah that will work

[quaint mantle]

ok thanks

and anyway to spawn a livingentity naturaly ?

like how zombies spawn

give the entity spawn chance

[quasi flint]

https://www.spigotmc.org/threads/natural-spawn-for-custom-entity.422292/

[quaint mantle]

that could not help cause im not using nms for the mob

[quasi flint]

?

[quaint mantle]

and the thread did not explained

[quasi flint]

packets?

[quaint mantle]

[burnt current]

Hey! short question:
I try to connect my Spigot plugin with a MySQL Database. For this purpose I have created the following class:
https://hastebin.com/qinejabexa.java
My config for this looks like this:
https://hastebin.com/juxirokuni.yaml
This is what my Main Class looks like:
https://hastebin.com/nulupijaha.java

Then when i start the plugin i get the following error:
https://hastebin.com/zowajuwipu.sql

where the most important places would be the following:

at de.straussfalke.straussfalkeserverplugin.MySQL.DataSourceProvider.testDataSource(DataSourceProvider.java:32) ~[?:?]
        at de.straussfalke.straussfalkeserverplugin.MySQL.DataSourceProvider.initMySQLDataSource(DataSourceProvider.java:27) ~[?:?]
        at de.straussfalke.straussfalkeserverplugin.Main.onEnable(Main.java:41) ~[?:?]```

These all lead to the line `try (Connection conn = dataSource.getConnection()) {`
Which can be found in the first link / class I sent in the `testDataSource` method.

Unfortunately, I don't know what I could have done wrong and therefore wanted to ask for help here.

[eternal oxide]

You use static everywhere so you never initialize your Main instance in yoru DataSource

English

[burnt current]

oh sorry 😅

so i should make my Methods in my MySQL Class unstatic?

[eternal oxide]

yes, call them via your dataSource instance not static

[burnt current]

so wait...
I just need to make this unstatic?:

public static DataSource initMySQLDataSource() throws SQLException {
        MysqlDataSource dataSource = new MysqlConnectionPoolDataSource();

                dataSource.setServerName(Main.instance.getConfig().getString("host"));
                dataSource.setPortNumber(Main.instance.getConfig().getInt("port"));
                dataSource.setDatabaseName(Main.instance.getConfig().getString("database"));
                dataSource.setUser(Main.instance.getConfig().getString("user"));
                dataSource.setPassword(Main.instance.getConfig().getString("password"));

                testDataSource(dataSource);
                return dataSource;
    }

    private static void testDataSource(DataSource dataSource) throws SQLException {
        try (Connection conn = dataSource.getConnection()) {
            if(!conn.isValid(1000)) {
                throw new SQLException("Database not connected");
            }
        }
    }```

[eternal oxide]

and fix your main

dataSource = new DataSource(this)

[burnt current]

so I should remove private DataSource dataSource;.
and replace dataSource = DataSourceProvider.initMySQLDataSource(); from my try cathc block in the main method with your example?

[eternal oxide]

no

teh Field is fine

but you are never instancing your DataSource

[burnt current]

I do that in my try catch block in my on enable method.

try{
            dataSource = DataSourceProvider.initMySQLDataSource();
            if(dataSource.getConnection() != null)
                Bukkit.getLogger().info("MySQL Database connected!");
            else {
                getLogger().log(Level.SEVERE, "MySQL database connection is null");
                return;
            }

        } catch(SQLException e) {
            getLogger().log(Level.SEVERE, "Could not establish MySQL Database Connection ", e );
            return;
        }```

[eternal oxide]

No you don't you never pass an instance of main to the constructor. You static access

[burnt current]

Sorry, I don't quite understand what you mean.

[eternal oxide]

You only ever access your DataSource via static methods. The class requires a reference to Main, which you never pass it as you never instance call the class.

You never call its constructor

[burnt current]

ok and where and how can i do this right?

[eternal oxide]

I told you. Remove all your static methods and instance your class in your main with dataSource = new DataSource(this);

[burnt current]

ok so i made public static DataSource initMySQLDataSource() to public DataSource initMySQLDataSource()
and private static void testDataSource(DataSource dataSource) to private void testDataSource(DataSource dataSource)
and i edited my onEnable method so it looks like this:

@Override
    public void onEnable() {
        String s;
        instance = this;
        this.saveDefaultConfig();
        dataSource = new DataSource(this);
        try{
            dataSource = DataSourceProvider.initMySQLDataSource();
            if(dataSource.getConnection() != null)
                Bukkit.getLogger().info("MySQL Database connected!");
            else {
                getLogger().log(Level.SEVERE, "MySQL database connection is null");
                return;
            }

        } catch(SQLException e) {
            getLogger().log(Level.SEVERE, "Could not establish MySQL Database Connection ", e );
            return;
        }
    }```

[eternal oxide]

DataSourceProvider?

if thats teh name you need to instance that. dataSource = new DataSourceProvider(this);

your init method doesn;t need to return anything

dataSource = new DataSourceProvider(this);
try {
   dataSource.initMySQLDataSource();```

[burnt current]

ok i have done that. but new DataSourceProvider(this) gives me an error in my IDE: expexted 0 arguments but found 1. then when I remove this it tells me that it needs a DataSource type and I have provided it with a DataSoruceProvider. I guess because I created the variable before with private DataSource dataSource;.

so should I then also change private DataSource dataSource; to private DataSourceProvider dataSource;?

[eternal oxide]

in your main yes

[burnt current]

okay

now the line if(dataSource.getConnection() != null) gives an error: cannot resolve 'getConnection' in 'DataSourceProvider'

[eternal oxide]

Your DataSourceProvider is a wrapper, so you need to expose methods in that to access your database

you should not expose the database connection directly

also MysqlDataSource dataSource needs to be a field in the class as you are accessing it from other methods.

[calm whale]

hey guys does anyone know what is this error ? Invalid entity rotation: NaN, discarding

i do not rotate any entity except a guardian laser from this resource: https://www.spigotmc.org/threads/laser-guardian-and-crystal-beams-1-9-1-17.348901/

[opal juniper]

it just means you cannot pass a NaN to the method

[eternal oxide]

NaN = Not a Number

[opal juniper]

idk where you are getting it tho

[calm whale]

I'm not sure but I think I get it when I disconnect my account during this code which is executed in a repeating task

for(Player p : WORLD.getPlayers()){

  if(!lasers.containsKey(p.getUniqueId()) /*&& p.getGameMode() == GameMode.SURVIVAL*/){
    createBeam(p, WORLD, lasers);
  }

  try {
    if(p.isOnline())
      lasers.get(p.getUniqueId()).moveEnd(p.getLocation());
    else
      lasers.get(p.getUniqueId()).stop();
  } catch (ReflectiveOperationException e) {
    e.printStackTrace();
  }

}```

[opal juniper]

what is the whole error- is there a stack trace?

[calm whale]

well I get nothing else that a huge spam of Invalid entity rotation: NaN, discarding even when I have no more laser beam

I thought it was because I was disconnected so I added the isOnline check

[opal juniper]

hmm doubt

[calm whale]

but it didn't fix it

[eternal oxide]

That online check is pointless

[calm whale]

yup I sure about that now

the world.getPlayers already does it

[eternal oxide]

you also know that when no one is online the for loop will never enter so you can;t stop any lasers

[calm whale]

ok I'm gonna edit this to loop through the hashmap keys

[opal juniper]

i imagine the error is coming from the method

*class

[eternal oxide]

You'd probably be better looping your lasers rather than players

[burnt current]

ok so now i created a MySQLDataSource Variable in my main. but what should my getConnection method look like?

[eternal oxide]

Not in main, in your DataSourceProvider

[burnt current]

there i already have this Variable

[eternal oxide]

You need it as a Field not a variable

[burnt current]

how should that looks like?

[eternal oxide]

a variable is inside a method. A Field is a class level variable.

you have it as a variable in a method at the moment. It needs to be a Field

[burnt current]

does i understand that right that i just should put the Variable outside of the Method?

[eternal oxide]

yes

https://www.java-made-easy.com/variable-scope.html

https://www.w3schools.com/java/java_scope.asp

[calm whale]

ok

so

here is my new code: https://hastebin.com/pezoyirune.kotlin

it works

but

the the problem was not what I expected

the error occurs when I have a laser beam running and I call this code

Random r = new Random();
        int max = r.nextInt(10 - 5) + 5;
        count = 0;

        fireballTask = new BukkitRunnable(){

            @Override
            public void run(){

                if(count >= max)
                    cancel();

                for(int i = 0; i < GameSettings.FIREBALLS_COUNT; i++){

                    int x = r.nextInt(50 + 50) + -50;
                    int z = r.nextInt(50 + 50) + -50;

                    Location loc = new Location(WORLD, x, 90, z);
                    Fireball ball = loc.getWorld().spawn(loc, Fireball.class);
                    ball.setIsIncendiary(false);
                    ball.setDirection(WORLD.getHighestBlockAt(x, z).getLocation().toVector().subtract(loc.toVector()).normalize().multiply(2f));

                }

                ++count;

            }
        }.runTaskTimer(RushToTheBeacon.getInstance(), 0, 15);```

[burnt current]

ok and then i have created a getConnection method which looks like this:

 public DataSource getConnection() {
        try {
            dataSource.getConnection();
        } catch (SQLException throwables) {
            throwables.printStackTrace();
        }
        
    }```
so there is missing a return statement and im not sure what i should return there

[quaint mantle]

Hello , does i can check if "beacon" word is exist in config file?

i have tried to use getStringList().contains

but not works for me

example

[eternal oxide]

you return dataSource.getConnection(); or null

[quaint mantle]

Location:
 spawn: x, y, z
 pvp: x,y,z```

so i want to check if pvp is exist

okay @eternal oxide

[eternal oxide]

that is not a list its a map

[tardy delta]

file.getString("Location.pvp") != null?

[quaint mantle]

@tardy delta not works

bcz

Location.pvp is not exist

i just want to check

if it's exist or not

[quasi flint]

well that deos excstcky that

excactly

[tardy delta]

doesnt it return null when not exist?

[quasi flint]

when its null it just stops

if it ecusts it continues

exists

[tardy delta]

oh :/

[quasi flint]

u can prob add a !

[fading pulsar]

Hi I want write a double xp plugin
But my plugin doesn't trigger PlayerExpChangeEvent(Console don't have "test: (Amout)" Who can teach or help me answer the question

@EventHandler
    public void expchange(PlayerExpChangeEvent event) {
        Player player = event.getPlayer();
        int getexp = event.getAmount();
        int int_val = Integer.parseInt(getConfig().getString("default.expdouble"));
        int TotalAmout = (getexp * int_val);
        player.setExp(TotalAmout);
        Bukkit.getConsoleSender().sendMessage(ChatColor.DARK_GRAY + "test: " + int_val);
    }

[quasi flint]

if u want to do smth when its null

registered it in the main?

[fading pulsar]

me?

[quasi flint]

yes

[fading pulsar]

public class Main extends JavaPlugin implements Listener {

[quasi flint]

no in ur onEnable

[quaint mantle]

try {
        if (LocationManager.Config.getString("Spawns.pvp") != null) {
            // code
        } 
} catch (NullPointerException nullPointerException) {
    nullPointerException.printStackTrace();
}```
like this ? @quasi flint @tardy delta

[tardy delta]

FileConfiguration#contains(String)?

[fading pulsar]

public void onEnable() {
        Bukkit.getConsoleSender().sendMessage(ChatColor.DARK_GRAY + "=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=");
        Bukkit.getConsoleSender().sendMessage(ChatColor.GREEN + "DoubleExpPlugin" + ChatColor.BLUE + "Enabled");
        Bukkit.getConsoleSender().sendMessage(ChatColor.RED + "Author: Dainner#2085" + ChatColor.WHITE + " | "

        this.saveDefaultConfig();
        this.getServer().getPluginManager().registerEvents(this, this);
    }

this?

[tardy delta]

dont catch npr

[quaint mantle]

i tried that , not works

[tardy delta]

heh

[quasi flint]

do smth when it hullpoints

[quasi flint]

interresting. should work

u @override the method

remove this.

only getServer.blablabla

[fading pulsar]

remove what

getPluginManager()?

[tardy delta]

work with \n

[quasi flint]

change this.getServer to getServer.getPluginManager etc

just remove the this.

[fading pulsar]

getServer.getPluginManager().registerEvents(this, this);
this?

[tardy delta]

doesnt really matter

yea

[quasi flint]

yea

wont change a thing

its just lookin better

[fading pulsar]

no it just look error

[quasi flint]

that shouldnt happen

whats the error?

[fading pulsar]

getServer cannot be resolved

[quasi flint]

send ur whole class

?paste

[quaint mantle]

[fading pulsar]

Oh

[quasi flint]

oh i did not notice that

[quaint mantle]

why this method is deprecated
why things like potioneffettype or entitytype getbyname method is not

[quasi flint]

whats jt saying?

[fading pulsar]

But same no't trigger

[quaint mantle]

send the class

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

[quasi flint]

@quaint mantle Its an old method

[quaint mantle]

is there any other way for it ?

[quasi flint]

new one is getByKey

[quaint mantle]

and how to get it with a namespacedkey ?

[quasi flint]

Enchantment.getByKey(NamespacedKey key);

[fading pulsar]

1.    public void expchange(PlayerExpChangeEvent event) {
2.      Player player = event.getPlayer();
3.      int getexp = event.getAmount();
4.      int int_val = Integer.parseInt(getConfig().getString("default.expdouble"));
5.      int TotalAmout = (getexp * int_val);
6.      player.setExp(TotalAmout);
7.      Bukkit.getConsoleSender().sendMessage(ChatColor.DARK_GRAY + "test: " + int_val);
8.    }

line 7 edit to line 2
line 2 edit to line 7
Console have send( "test: " + int_val) But now no't send ("test: " + int_val)

[mossy laurel]

Is there a way to load dependency in-runtime with 'libraries' section, while dependency isn't in maven central? Specifing repository or something.

[quasi flint]

Enchantment.getByKey(NamespacedKey.minecraft(name));
}

[quasi flint]

dont think so

not sure tho

[quaint mantle]

new NamespacedKey(instance, "enchant") ?

like this ?

oh

wait

[quasi flint]

no u did not

[fading pulsar]

！？

[quasi flint]

look at my link

[quaint mantle]

what could be null here should i ignore it ?

[quasi flint]

there it explains now

his hand could be null

prob ignore it

or maybe try catch

i dunno

[quaint mantle]

ok thx

[quasi flint]

i would ignore it

[fading pulsar]

Emm i just write all in Main

[quaint mantle]

You didn't register a command in onEnable()

[fading pulsar]

But it can use

this project is All code in one file

[quaint mantle]

You still need to register the command

[fading pulsar]

Error。

[quaint mantle]

iirc you have to to use this

[paper viper]

just saying, you should really at least learn basics like importing

[paper viper]

no..

this is already referring to the plugin

you cant set the command executor to the same plugin

you have to define a new instance of the command executing class

he just isnt importing it

or the class name is wrong

[quaint mantle]

Mhh idk, i never put all code in one file. :^)

[fading pulsar]

I never put the code in more than two files :^)
because my plugin all just have reload command
no't other command

[quasi flint]

which is a bad waynof doing java shit

of

i test the event

i thought i saw dutch

[fading pulsar]

@EventHandler
    public void expchange(PlayerExpChangeEvent event) {
        Player player = event.getPlayer();
        int getexp = event.getAmount();
        int int_val = Integer.parseInt(getConfig().getString("default.expdouble"));
        int TotalAmout = (getexp * int_val);
        player.setExp(TotalAmout);
    }

this ( player.setExp(TotalAmout); ) no't trigger but... why?

[quasi flint]

german geo io hitting different

[tardy delta]

learning german verbs rn 😢

[quasi flint]

because the event is not executed

in dont know what u made wrong

[quasi flint]

Hallo Freund

[tardy delta]

Guten Tag

maybe one word smh

[quasi flint]

well morning is the first step

but german is hard af

how long u learned it for now?

[tardy delta]

uhh 2 years in school

[quasi flint]

i see

[fading pulsar]

https://paste.md-5.net/uwesapuduv.cs
test over。

[tardy delta]

still dont get the A2 on my level test 😳

[quasi flint]

it worked so whats wrong?

[quasi flint]

ouch

[fading pulsar]

just no't trigger "f" ( no trigger player.setExp )

[tardy delta]

or maybe just

[quasi flint]

setExp uses doubles

if i recall coreectly

[fading pulsar]

Oh！

let me edit and try

[quasi flint]

but i dont know for certain

[tardy delta]

doesnt matter calling an int where it expects a double

[quasi flint]

rounding be gone tho

[fading pulsar]

is float

[quasi flint]

then di what u have to do

[fading pulsar]

but same no't trigger xD

[ancient plank]

no't

[quasi flint]

🍞

[fading pulsar]

@EventHandler
    public void ExpChange(PlayerExpChangeEvent event) {
        Player player = event.getPlayer();
        int getexp = event.getAmount();
        int int_val = Integer.parseInt(getConfig().getString("default.expdouble"));
        int TotalAmout = (getexp * int_val);
        float d=(float) TotalAmout;
        player.setExp(d);     <<this no't trigger
    }

[tardy delta]

making three ints and a float inside a method 🤔

[quasi flint]

castjng an int to an float

ouch

[ancient plank]

🤔

double to int to float

[tardy delta]

@EventHandler
public void onExpChange(PlayerExpChangeEvent event) {
  Player player = event.getPlayer();
  player.setExp(event.getAmount() * Double.parseDouble(getConfig().getString("default.expdouble")))
}

?

[fading pulsar]

player.setExp(event.getAmount() * Integer.parseInt(getConfig().getString("default.expdouble"))); <<< this doesn't trigger
😦

[ancient plank]

doesn't

[tardy delta]

set the amount to a very high and check if it works

[fading pulsar]

default:
  expdouble: "10.0"

Emmm my check is

@EventHandler
    public void onExpChange(PlayerExpChangeEvent event) {
      Bukkit.getConsoleSender().sendMessage(ChatColor.DARK_GRAY + "a");
      Player player = event.getPlayer();
      Bukkit.getConsoleSender().sendMessage(ChatColor.DARK_GRAY + "b");
      player.setExp(event.getAmount() * Integer.parseInt(getConfig().getString("default.expdouble")));
      Bukkit.getConsoleSender().sendMessage(ChatColor.DARK_GRAY + "c");
    }

www (Console doesn't send "c")

[young knoll]

There is a getInt for config you know

[eternal oxide]

you can't getInt on a double

[echo basalt]

and I'm pretty sure you're coming into floor(num) issues when casting to int

[fading pulsar]

i very sure is

player.setExp(event.getAmount() * Integer.parseInt(getConfig().getString("default.expdouble")));

dosen't trigger

[eternal oxide]

that line is probably throwing an exception so C never prints

[fading pulsar]

But i don't know what's is the problem

[eternal oxide]

show your config that has the default.expdouble

[fading pulsar]

default:
  expdouble: "10.0"

[eternal oxide]

why are you using a string/double?

[paper viper]

Double.parseDouble

that's a decimal btw

i dont think the parseInt supports .0

[fading pulsar]

The method setExp(float) in the type Player is not applicable for the arguments (double)

[paper viper]

then do Float.parseFloat

[quasi flint]

that says what u have to do

[paper viper]

i dont see a point of actually using float

maybe you should use double if you wanted to lol

for precision

Anyone managed to have different textures to same armor in 1.12.2 or lower?

I tried durablity but minecraft forces the normal texture when equipping so im really curious if there is a solution for this in version under 1.14

[tardy delta]

weewoo

[ancient plank]

a server I used to dev for made use of NBT tags and optifine, idk any other solution

you can set nbt tags with a name, and optifine / mods can read the nbt tags on an item and apply different textures to them

[quasi flint]

it says

woops

wrong channel

[quaint mantle]

Hello so i'm asking for does i can make a cooldown
but when the server restarts it's saving the cooldown with out reset it

[gaunt hatch]

hmm is it just me or does it seem in 1.17(+) the world chunk(s) don't seem to want to unload at all.

[tardy delta]

the timestamps part gives you a base
https://www.spigotmc.org/wiki/feature-command-cooldowns/

but it needs some changes

[stoic ravine]

@ancient plank doesnt everyone need to have optifine then?

[ancient plank]

yes.

that's why I said its a solution

[stoic ravine]

Yeee thanks, you cant force palyers to auto download optifine like you can force them to download a texture pack if they allow it?

[ancient plank]

na you can't force them

its one of those things where you have to coerce them like "If you download optifine with our resource pack you can see these awesome textures"

[stoic ravine]

ye true i guess

[robust forge]

What would be the best way to register multiple listener classes?
Normally I would do:
Bukkit.getPluginManager().registerEvents(new Class_Name(), this);
But is there a better method to do that for bigger core plugins? For example if I have 30 classes that implements listener can I somehow loop trough all of them and register them? The code looks pretty bad with one big chunky method that has 30 rows of the example code.

[stoic ravine]

sad only that there is no real solution. but ye that sounds good cuz ill just have decent textures for those who dont use optifine

[tardy delta]

PluginManager pm = Bukkit.getPluginManager();
pm.registerEvents(new Listener, this);
...

or put them into an array and loop over them idk

[robust forge]

Yeah but I dont want to have 30 rows of
pm.registerEvents(new Listener, this);

[gaunt hatch]

you could use reflection

[tardy delta]

^^

[robust forge]

Any example?

[gaunt hatch]

that is some advance stuff man, might want to learn refection before you start playing with it, you can do so bad damage with it

[tardy delta]

[gaunt hatch]

that works lol

[tiny wolf]

Hey anyone know why when I save my bungee config it completely removes comments and reformats it ?

[tardy delta]

thats just the api

you could create a new one but that goes brr

[tiny wolf]

oof really

why did they make the spigot one way better lmao

[tardy delta]

🤷

its just the same with spigot

[tiny wolf]

with spigot it keeps it the same when you save it

[gaunt hatch]

Anyone know what is up with chunks and not wanting to unload in 1.17(+)

[solid cargo]

any way a custom entity can drop an item while its still alive

[burnt current]

ok. i have done that... but the same error still comes

[hasty prawn]

Just spawn an item at it's location

[solid cargo]

may i ask whats the method

[hasty prawn]

World#dropItem or World#dropItemNaturally, depending on if you want the item to have a velocity or not.

[golden turret]

how could i detect when a method is being called? using reflection

[solid cargo]

thanks <3

[eternal oxide]

what same error?

[burnt current]

[hasty prawn]

What's in the config

Don't send the password, just the other fields

[burnt current]

MySQL:
  host: localhost
  port: 3306
  database: straussfalkeplugins
  user: Server
  password: <password>```

[eternal oxide]

you are setting all your dataSource values to null

getString("host") will return null as its "MySQL.host"

[burnt current]

oh yeah sure. i will fix that

okay the error is gone but now comes [StraussfalkeServerPlugin] MySQL database connection is null What was created by the user and should come exactly when the database connection corresponds to zero.

[shy wedge]

Hey, is there something like Location.distance() but it ignores Y coordinate?

[ivory sleet]

Just manipulate y?

[burnt current]

try{
            dataSource.initMySQLDataSource();
            if(dataSource.getConnection() != null)
                Bukkit.getLogger().info("MySQL Database connected!");
            else {
                getLogger().log(Level.SEVERE, "MySQL database connection is null");
                return;
            }

        } catch(SQLException e) {
            getLogger().log(Level.SEVERE, "Could not establish MySQL Database Connection ", e );
            return;
        }

is the corresponding code

[ivory sleet]

You can set one’s y to the other’s y value

[chrome beacon]

You can always calculate the distance yourself or set the location y so they match

Why did that take 20 seconds to send

Discord u good

[shy wedge]

lol

Indeed, very smart thanks

[eternal oxide]

are you returning the correct type from getConnection() ?

it should be returning a Connection, not a DataSource

[burnt current]

I had now specified null as the return type, since you said earlier that I can return either dataSource.getConnection or null.

public DataSource getConnection() {
        try {
            dataSource.getConnection();
        } catch (SQLException throwables) {
            throwables.printStackTrace();
        }
        return null;
    }

thats the Method

[eternal oxide]

no you return the result of getConnection, or null

return dataSource.getConnection();

[burnt current]

ok

[quaint mantle]

saddest moments in Java

[burnt current]

now it looks like that:

public DataSource getConnection() throws SQLException {
        try {
            dataSource.getConnection();
        } catch (SQLException throwables) {
            throwables.printStackTrace();
        }
        return (DataSource) dataSource.getConnection();
    }
}```

[eternal oxide]

remove the cast and make the method return a Connection

[quaint mantle]

why did you cast it

what is happening right now

[burnt current]

It was a suggestion from the IDE so I thought it would be useful.

[quaint mantle]

weird

[eternal oxide]

you are returning a Connection not a DataSource

[burnt current]

yes i changed it

[eternal oxide]

your IDE is too dumb to tell whats wrong

[burnt current]

yeah the Database now has connected

[old cloud]

Hello. I want to store an area of blocks so I made a wrapper class to serialize BlockState Objects. The problem is that it obviously doesn't save the content of a chest or of a sign. How can I store those values as well?

[burnt current]

Thank you so much for your help and sorry for the trouble I have caused

[eternal oxide]

Your code but cleaned up a little https://paste.md-5.net/usudobasup.java

[old cloud]

Is there a general type storing such values or do I need to check for those specific Blocks and then get the data manually?

[hasty prawn]

BlockState I think is what you want.

[old cloud]

Okay but how can I serialize that and how would I set any Block into that specific BlockState?

[burnt current]

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

[vernal pier]

You can save the nbt of the tile data

[eternal oxide]

dataSource = new DataSourceProvider();

needs to be dataSource = new DataSourceProvider(this);

[old cloud]

How does that work?

[slim kernel]

would be really nice if anyone could help me pls

[burnt current]

i tried that. But then the IDE says Expected 0 arguments but found 1

[eternal oxide]

then your DataSourceProvider is wrong. Its constructor shoudl be public DataSourceProvider(JavaPlugin plugin) {

[old cloud]

At the end

after .build()

[slim kernel]

yeah I know but how exactly I dont get it to work somehow pls give me an Example

[old cloud]

You could do it with Arrays.asList(...)

[burnt current]

I also just noticed that this line also doesn't throw an error when I remove the method from my DataSourceProvider class

[pastel coyote]

    public static String f(String s) {
            return ChatColor.translateAlternateColorCodes('&', "{prefix}" + s);

[solid cargo]

ayo can someone tell me on how to declare a world. im asking cause im tired asf and not functioning

[slim kernel]

and what do I put in the brackets?

[old cloud]

all the Elements you want in the list

[tardy delta]

why is this redundant? i just check if the player already executed that command and increase the teller if thats true
if (uses.get(uuid) < 2) uses.put(uuid, uses.get(uuid) + 1);

[hasty prawn]

You're not doing anything in it

[tardy delta]

well i check if its smaller than 2 and then teleport them

[hasty prawn]

Oh wait nvm

[slim kernel]

But I want arrayLists for each element so I can put players in each of them, not putting elements in Lists

[hasty prawn]

I read it wrong

[tardy delta]

oh

[old cloud]

Then do new ArrayList<UUID>();

or <Player> depending on what you want to store

[slim kernel]

oh yes thank you alot

[old cloud]

np

[tardy delta]

and what does inlining mean?

[pastel coyote]

https://lmgtfy.app/?q=inlining+java

[hasty prawn]

You don't need to assign getLocation(p, name) to a variable since you only use it once.

Just put getLocation(p, name) where you use loc.

[old cloud]

Dont you also just serialize the BlockData?

[tardy delta]

but if its null i want to return

[pastel coyote]

remove the void from your public void? is that what you want?

[tardy delta]

?

[pastel coyote]

is there a class you want to return?

[tardy delta]

just return in a void smh

[pastel coyote]

what do need help with? 🤔

[toxic mesa]

I got a packet listener and stuff and got this

            PacketPlayInPosition posPacket = (PacketPlayInPosition) packet;
            Bukkit.broadcastMessage("x: " + posPacket.a);
            Bukkit.broadcastMessage("y: " + posPacket.b);
            Bukkit.broadcastMessage("z: " + posPacket.c);
            Bukkit.broadcastMessage("possible ground boolean: " + posPacket.g);
            Bukkit.broadcastMessage("possible ground boolean2: " + posPacket.h);

x y and z are correct and stuff but there are 2 booleans which are g and h. I was expecting one of them to be the onGround boolean and yet 1 is a constant true and the second is a constant false. Any way I can get the onGround value from the packet?

[old cloud]

(seconds / 60) + ":" + (seconds % 60)

[eternal oxide]

if its just a standard block, yes

https://github.com/ElgarL/Regen/blob/ad1259a42d81f9fd47a6411afcc697321a6c3a9b/src/com/palmergames/spigot/regen/serialize/SerializedBlock.java#L155

[old cloud]

But I think there is actually a better way, not sure atm

[eternal oxide]

quite possibly

[hasty prawn]

@tardy delta https://paste.md-5.net/nukofufode.cs that's how I would do it. I didn't really check your time messages. I don't really know why you're converting it to days, but I assume you have your reasons?

[upper vale]

Use %02d for the minutes if you want it like 03 instead of 4

*3

[old cloud]

Yes and where do you store the other stuff?

[eternal oxide]

other stuff?

[old cloud]

Like the text of a sign, content of a commandblock or chest, etc...

[eternal oxide]

These are extensions for special blocks. Look at teh serialize method https://github.com/ElgarL/Regen/tree/master/src/com/palmergames/spigot/regen/serialize/extensions

@eternal oxide I have another question regarding MySQL. How should I create my methods to insert something into my table?

[late dove]

How to place a player in a worldguard group? I need this for a different number of private players. I'm sorry for the question.

[slim kernel]

Just one last question: do I need to register the arrayList somehow?

[old cloud]

No

[slim kernel]

okay thank you

[eternal oxide]

create a utility class with prepared statement constructors or Builders.

[burnt current]

do you have an example?

[eternal oxide]

no

[old cloud]

But these are not all?

Because command block for example isnt there

[eternal oxide]

I never tested on a command block

[burnt current]

that is a pity

[eternal oxide]

mainly because a command block should not be anywhere near TNT

[old cloud]

Yea

[eternal oxide]

I didn;t think about it honestly

[old cloud]

Can't I just get all the NBT data or something and store that?

[eternal oxide]

No clue, I only use the API

[burnt current]

I had already found an example:

public boolean someMethod(Object obj1, Object obj2) {
    try (Connection conn = conn(); PreparedStatement stmt = conn.prepareStatement(
            "INSERT INTO player_coins(uuid, coins) VALUES(?, ?);"
    )) {
        stmt.setSomething(1, obj1);
        stmt.setSomething(2, obj2);
        stmt.execute();
        return true;
    } catch (SQLException e) {
        logSQLError("Something went wrong.", e);
    }
    return false;
}```
but I don't know what the conn() method should look like in that case

[eternal oxide]

thats a connection you get from your provider

[burnt current]

like this?:

public Connection getConnection() {
        try {
            return dataSource.getConnection();
        } catch (SQLException throwables) {
            throwables.printStackTrace();
        }
        return null;
    }```

[hasty prawn]

Couldn't you technically use reflection to get all the values and serialize those?

Not sure how it would know what to save and what not to save, but it would atleast be able to be generalized over all the special block cases

[ivory sleet]

Ye

You could just include a strategy pattern for the exclusion

[hasty prawn]

True. I assume most the stuff you'd want excluded is in the main BlockState class anyways. All the stuff within the subclasses are probably pretty important

[ivory sleet]

[tardy delta]

worldguard hates me, i've set some neccesary flags up and when i leave a horse worldguard says that i may not leave because i cant re enter, i overrid that event so you can leave them but now i cant enter horser :/

and worlguard thinks i'm still on that horse while i'm not

[crimson terrace]

is there a way to keep a creeper from despawning when it explodes?

[ivory sleet]

I believe not

Unless you’d fake the explosion

[chrome beacon]

I'd just spawn an explosion

[crimson terrace]

totally related question: can I spawn an entity into the world which I made before? aka spawn the creeper into the world after it disappears

[tardy delta]

event priority highest is executed the last right?

[ivory sleet]

iirc no

Monitor is last

[chrome beacon]

^

[hasty prawn]

It is

[tardy delta]

but monitor cant cancel the event?

[ivory sleet]

It can

Just by convention shouldn’t

[tardy delta]

that

[chrome beacon]

Don't cancel in Monitor

[ivory sleet]

Altho plugins like LuckPerms do it

[hasty prawn]

smh

[tardy delta]

i want to decide as last whether or not to cancel the event

to override worldguard smh

[burnt current]

like this?:

public Connection getConnection() {
        try {
            return dataSource.getConnection();
        } catch (SQLException throwables) {
            throwables.printStackTrace();
        }
        return null;
    }```

[ivory sleet]

Or well, they disallow login at monitor state so idk it’s exactly the same thing but yeah

[hasty prawn]

I'm sure they have somewhat good reasoning behind doing it that way.

[ivory sleet]

Idk

Some of the design in luckperms is questionable, not because I write the most godly code myself

[hasty prawn]

[ivory sleet]

But they pass the plugin instance in so many classes

[hasty prawn]

Ah, instead of doing Singleton?

[tardy delta]

but which priority is executed last now?

[ivory sleet]

No dessie

[hasty prawn]

[crimson terrace]

if I do this, will the UUID of creeper be the same as the UUID of creeperNew?

[ivory sleet]

Thing is,they should pass their higher level components like their data managers and such instead of passing the plugin instance and then invoking blah.getDataManager()

imo

[hasty prawn]

Ahhh okay I'm with you now

[old cloud]

If you do this, then creeperNew will be the same object as creeper

[crimson terrace]

perfect

[old cloud]

Which is useless

because if you change something in "creeperNew" it will also be changed in "creeper" and visa versa because they are the same objects

[crimson terrace]

hm

ok got it. complicated fix it is

[toxic mesa]

Bump

[old cloud]

Anyone knows how to get and set the NBT (?) data of a block?

[tardy delta]

every time when a command is called, does that makes a new command instance?

[old cloud]

No, it just exectues "onCommand" of the registered "CommandExecutor" instance

[tardy delta]

so no new instance

ok

why cant i combine Item item = item blah blah blah with Bukkit.getScheduler

[solid cargo]

i dont have to make it drop?

i can just

do the drop in the runnable?

[old cloud]

ofc

[solid cargo]

how tho?
item.dropItem(new ItemStack(Material.MATERIAL)) ?

and also location and shiz ofc

but in general like that right?

[old cloud]

Just like that in your case: e.getDamager().getWorld().dropItem(e.getDamager().getLocation(), new ItemStack(Material.BOOK, 1))

[solid cargo]

yeah but what if i want to set the velocity

[old cloud]

just do

() -> {

}
```and you have infinite lines

[solid cargo]

thats why i need to like

ahh

[proud basin]

Why do custom fonts look stupid when your screen is full screened in minecraft

[old cloud]

Thats the general usage of a lambda expressions. Its just a short variant of creating a new instance of an interface with 1 method.

interface MyInterface {

    T method(A a, B b, C c, ...);

}

// First (standard) variant:

MyInterface k = new MyInterface() {
    
    @Override
    T method(A a, B b, C c, ...) {
          // do your stuff here
    }

};

// Second (lambda) variant:

MyInterface l = (a, b, c, ...) -> {
      // do your stuff here
};

And since Runnable's method "run" doesnt have any arguments, you leave it empty like that () -> {

[young knoll]

It actually does, you just don't use it often

[old cloud]

No?

[young knoll]

        Bukkit.getScheduler().runTaskTimerAsynchronously(this, (task) -> {
            task.cancel();
        }, 10, 10);

[old cloud]

Then that is not a java.lang.Runnable

[burnt current]

short question: I have connected my plugin to a MySQL database and have the following class for it: https://paste.md-5.net/novulovevu.java
now I would also like to insert data into my tables and ask how exactly I can do that? (I have already dealt with MySQL - I am only interested in the JDBC part). can anyone help me with this?

[young knoll]

Ah, though we were talking about the bukkit runnables

[floral pewter]

Hey, there seems to be a problem with creating stonecutter GUIs. Adding items to them via spigot seems to have no effect whatsoever. I've found this two-year-old issue on the forums which still seems relevant https://www.spigotmc.org/threads/unable-to-set-itemstack-in-stonecutter-inventory.389400/.

The code I'm using:

Inventory inventory = Bukkit.createInventory(player, InventoryType.STONECUTTER);
inventory.setItem(0, new ItemStack(Material.STONE));
player.openInventory(inventory);

The result

Switching out the inventorytype to chest, shulker et al. works fine, but the stonecutter is problematic

Calling Player::updateInventory after a tick or so does not work either

[lost matrix]

1. Try first opening then setting the ItemStack
2. Try updating the players view

[floral pewter]

Adding the itemstack afterwards gives the same result. Inventory::getContents shows the itemstack regardless if I add it before or after showing it

[lost matrix]

Also:

    StonecutterInventory cutterInv = (StonecutterInventory) inventory;
    cutterInv.setInputItem(item);

[floral pewter]

I'll try that

setInputItem does not seem to be a method of the StonecutterInventory class. Running ```java
StonecutterInventory inventory = (StonecutterInventory) Bukkit.createInventory(player, InventoryType.STONECUTTER);
inventory.setItem(0, new ItemStack(Material.COAL));

    player.openInventory(inventory);

gives `java.lang.ClassCastException: class org.bukkit.craftbukkit.v1_17_R1.inventory.CraftInventoryCustom cannot be cast to class org.bukkit.inventory.StonecutterInventory (org.bukkit.craftbukkit.v1_17_R1.inventory.CraftInventoryCustom and org.bukkit.inventory.StonecutterInventory are in unnamed module of loader 'app')`

[lost matrix]

Thats weird...

[floral pewter]

Very...

Perhaps I should try importing version-specific craftbukkit

[crimson terrace]

can I cancel the EntityTargetEvent without it costing too many resources?

[floral pewter]

CraftInventoryStonecutter inventory = (CraftInventoryStonecutter) Bukkit.createInventory(player, InventoryType.STONECUTTER);

inventory.setItem(0, new ItemStack(Material.COAL));
player.openInventory(inventory);

Gives java.lang.ClassCastException: class org.bukkit.craftbukkit.v1_17_R1.inventory.CraftInventoryCustom cannot be cast to class org.bukkit.craftbukkit.v1_17_R1.inventory.CraftInventoryStonecutter (org.bukkit.craftbukkit.v1_17_R1.inventory.CraftInventoryCustom and org.bukkit.craftbukkit.v1_17_R1.inventory.CraftInventoryStonecutter are in unnamed module of loader 'app'), which to me is even stranger

[lost matrix]

Try this workaround.

  private final Map<HumanEntity, Consumer<StonecutterInventory>> cutterPrepMap = new HashMap<>();

  public void openStoneCutterFor(final Player player, final Consumer<StonecutterInventory> prepConsumer) {
    final Inventory inventory = Bukkit.createInventory(null, InventoryType.STONECUTTER);
    this.cutterPrepMap.put(player, prepConsumer);
    player.openInventory(inventory);
  }

  @EventHandler
  public void onOpen(final InventoryOpenEvent event) {
    final Consumer<StonecutterInventory> consumer = this.cutterPrepMap.remove(event.getPlayer());
    if (consumer != null) {
      consumer.accept((StonecutterInventory) event.getInventory());
    }
  }

...

  openStoneCutterFor(player, cutterInv -> cutterInv.setInputItem(item));

[lost matrix]

It all depends on how you implement it.

[crimson terrace]

its not too heavy

I guess my question is "How many times does it get called"

[lost matrix]

Why do you have the same check twice?

Ah wait

[crimson terrace]

I want the enderman not to target the mite and the other way around

[worldly ingot]

getTarget().getType() vs getEntityType() ;p

[floral pewter]

Sadly, this doesn't do the trick either

Still getting an empty stonecutter

[lost matrix]

Do you get the same cast exception?

[floral pewter]

I do not

But nothing is showing in the stonecutter

[lost matrix]

Show your code pls

[crimson terrace]

that is the type of the entity that is targetting...

[worldly ingot]

No I know I was clarifying to smile's question there

[crimson terrace]

I specifically want the targetted type tho

[lost matrix]

Add a sysout to the consumer and check if it actually ran

[crimson terrace]

oh ok

thought you were saying "replace this with that"

my bad

[lost matrix]

You can have a little performance enhancement by returning after the first event.setCancelled()

[crimson terrace]

cats can have a little salami.

programmers can have a little performance enhancement

😄 good tip. will do

[floral pewter]

Aha! The event handler fires, but the consumer does not

[minor garnet]

who is best to use, reflection or interface ?

[ivory sleet]

For what?

[minor garnet]

for nms classes

[ivory sleet]

I go with both

[minor garnet]

:

[ivory sleet]

I use some sort of abstraction, but if I have no concrete implementation for the interface I fallback to some good old nms

[lost matrix]

Interfaces perform better.
If you know how to properly cache your reflections then they get also really performant with enough time on the JIT

[floral pewter]

I am worried about not finding the setInputItem method

[ivory sleet]

Yeah well sadly Java 8 doesn’t have all those reflection optimizations I believe newer versions have in case you’re a legacy fan

[minor garnet]

sure

[lost matrix]

What version are you on?

[floral pewter]

1.17.1

Spigot, remapped

[lost matrix]

Ah sry its not a spigot method

[floral pewter]

CraftBukkit?

Because that should be bundled through buildtools

[hasty prawn]

Is it setItem(int, ItemStack)?

[floral pewter]

That's what I see

[hasty prawn]

Is that not the same thing as setInputItem

Just named differently

[floral pewter]

setInputItem seems stonecutter-specific

Which in turn may run some stonecutter-specific update logic

[hasty prawn]

Hm, I don't know why they would've removed that method... I assume setItem(0, ItemStack) would effectively just be the same thing.

[floral pewter]

I would as well. I'm going to try capturing some packets to see if a specific slot is being used

[hasty prawn]

I mean I know Input is 0 and Result is 1 if that's what you're wondering.

[floral pewter]

ah

Perhaps an update packet is not sent

[hasty prawn]

There's static variables for them if you prefer to use those instead of 0 and 1

[floral pewter]

ah StonecutterMenu.INPUT_SLOT

[hasty prawn]

Yes

[floral pewter]

I'll use that, a nice alias :)

[young knoll]

So SmithingRecipes doesn't preserve the meta of the output, and if I use PrepareSmithingEvent#setResult I can't take the item out...

[floral pewter]

I solved it using NMS

StonecutterMenu stonecutterMenu = new StonecutterMenu(1, ((CraftPlayer) player).getHandle().getInventory());
stonecutterMenu.setTitle(new TextComponent("something"));

stonecutterMenu.setItem(StonecutterMenu.INPUT_SLOT, 0,CraftItemStack.asNMSCopy(new ItemStack(Material.COAL)));
player.openInventory(stonecutterMenu.getBukkitView());

For anyone interested

[young knoll]

I don't understand why I can't remove this item

[waxen plinth]

Try setting it in the InventoryClickEvent

[young knoll]

Hmm, good idea

Nope

[quaint mantle]

i have a question
if i changed integer value every 1 seconds using runnables
that will give low tps and high cpu usage or will it not affect?

[opal juniper]

every one second is not that much

it would have a negligible effect on the server

And if the task is as easy as you said it is, just simply setting an int var it would be such a fast operation

[quaint mantle]

i wanna try to make cooldown using runnables and config that why i asked

so the integer will change for so many players

i wan't to make a cooldown using config because if i want to save secondsleft

if there another way to save integer value when server restart can someone tell me about it?

[young knoll]

You could attach it to the players pdc I guess

[quaint mantle]

what is that xd

[young knoll]

?pdc

[undone axle]

https://www.spigotmc.org/threads/a-guide-to-1-14-persistentdataholder-api.371200/

[lost matrix]

You should not actively count down cooldowns.
Use a timestamp instead and calculate the time delta when the action is called again.

[quaint mantle]

good idea. so i just need to save the timestamp in config file and then check if the cooldown has expired right?

[lost matrix]

yes

[young knoll]

The problem with that is time continues when the server is offline

You could save the time left, and then recalculate the timestamp when it starts again

[lost matrix]

You mean the benefit

😄

[young knoll]

Depends if you want that I guess

[quaint mantle]

        Date date = new Date();
        SimpleDateFormat format = new SimpleDateFormat("HH:mm:ss");
        Main.getInstance().getConfig().set("Player.time", format.format(date));
        if (date > Main.getInstance().getConfig().get("Player.time")) {
            //code
        }```
it's should be like this?
but how to check if the new date bigger than  old date with 1hours?

and i have a error here xD if (date > Main.getInstance().getConfig().get("Player.time")) {

@lost matrix if you are not busy, can you help please?

[eternal night]

dates are not compared using the > operator

the > is for numeric primitive types

e.g. int,double

[quaint mantle]

mm so how to check if new date bigger than old date with 1hour ? @eternal night

[eternal night]

there is Date#before and Date#after

[quaint mantle]

well, how to use it with cooldown?
how i can set the Data before

date*

[eternal night]

final Date dateOneHourInTheFuture = new Date(System.currentTimeMillis() + TimeUnit.HOURS.toMillis(1));

[quaint mantle]

this will be saved if server has been restarted ? @eternal night

[eternal night]

what ?

no

pretty much on you how you are saving things

this just creates a date object that points to a time on hour in the future from when your code executed that created it

[quaint mantle]

oh

well thx dude

[rigid wyvern]

anyone familiar with how entities work on chunk load? I'm trying to prevent the pickup of certain items. when a player logs in, they have items in their inventory from the ground, but the code prevents pickup on items that weren't close enough to get picked up initially.

More info: https://www.spigotmc.org/threads/deleting-entities-before-a-player-can-pick-it-up.525979/

[toxic mesa]

So i'm used protocollib, I got this up and running and returning the correct value
player.sendMessage(PlaceholderAPI.setPlaceholders(player, "%PvpToggle_status%"));
What do I need to do for other plugins to be able to use this?

[rigid wyvern]

https://www.spigotmc.org/threads/how-to-make-a-placeholder-with-placeholderapi.91004/ this might help

[toxic mesa]

ty

[young knoll]

Why not set the pickup delay on the items

Let the game handle it

[rigid wyvern]

I tried using the delay, but then it never runs the pickup event to delete the entities

[young knoll]

Delete them on shutdown?

[rigid wyvern]

the issue comes from items being dropped for an effect, and then the server closing before the timer from that effect deletes them

wouldn't help with crashes tho no?

[young knoll]

No

Add a pdc tag to the item, delete nearby ones when a player logs in

[rigid wyvern]

atm I'm using item lore, which also helps me keep them from stacking with eachother, but it's not loading that before the pickup happens

I might do the pickup delay and delete on close. if they aren't deleted on server stop, they'll never be able to get picked up and someone will just need to burn them

[young knoll]

Like I said, pdc

[rigid wyvern]

would that work when the lore doesnt?

I figure all the data would get loaded at once

[young knoll]

It can be attached to the entity itself

Not the itemstack

[rigid wyvern]

oh hmm, I'll try that out then. thanks! 😄

[burnt current]

Hey Quick question: I would like to be able to insert values into the database via my database connection and have already created the following:

private DataSourceProvider dataSource;


    public Connection conn() {
        dataSource = new DataSourceProvider(Main.getPlugin());
        return dataSource;
    }

    public boolean addPlayer(UUID uuid, String playername, int coins) {
        try (Connection conn = conn(); PreparedStatement stmt = conn.prepareStatement("INSERT INTO playerdata (UUID, playername, coins) VALUES (?,?),")) {
        } catch (SQLException throwables) {
            throwables.printStackTrace();
        }
    }

However, return dataSource; returns an error because a connection is expected there.
I don't know what I have to change. Can anyone help me to correct this?

btw I have a related class that might be important: https://paste.md-5.net/novulovevu.java

[young knoll]

You gotta return dataSource.getConnection

Or change the return type

my load data method for player

but it could be runned again for example from place holder

asking for player data and running method again to load data but there could be one instance already in action

could I use here some how sync

or maybe I could made hashset like loading list

and put player uuid on start

in

and when finished remove it out

or on exception

[quaint mantle]

is there a reason why the PlayerCommandPreprocessEvent aint functioning ? its still doing the normal help

also check event sout isnt called

[vague oracle]

First use the plugins logger

as system out doens't really work (Idk why I Just know not to use it)

[hasty prawn]

System out works fine?

[quaint mantle]

weird since the sout on join works ( testing if events where working)

[hasty prawn]

Are you sure that your JAR is being updated @quaint mantle? That's really the only reason I can think that wouldn't be called at all.

[quaint mantle]

i manually overwrite it but ill check that one

works thanks

[dense shoal]

I have a Set of what are essentially chunks in a square and I want to get them into a WorldEdit region and copied with a ForwardExtentCopy

            ForwardExtentCopy forwardExtentCopy = new ForwardExtentCopy(
                editSession, region, clipboard, region.getMinimumPoint()
            );```
My thought process is to get the corner chunks of the Set. But I need to get the min/max coords of a chunk. Anyone know of a way to do that?

Please don't spoonfeed me, but a nudge in the right direction would be appreciated.

[regal dew]

find smallest chunk coordinates & biggest chunk coords

since its a square to get the min pos its just smallest chunk XYZ coordX * 16, 0, coordZ * 16

and for the max XYZ u do it with the max chunk but add 15 to the X and Z

[dense shoal]

smallest needed (-287,0,64)
{
"w": "world",
"cx": -18,
"cz": 4
}
X (-18 * 16) + 1 = -287
Z (4 * 16) = 64

largest needed (-240,4,255)
{
"w": "world",
"cx": -16,
"cz": 6
}
X (-16 * 16) - 16 = 240
Z 6 * 16 + 15 = 111

These are my calculations, this isn't completely adding up

https://i.imgur.com/QQh0rJr.png where smallest is blue and largest is red

[regal dew]

umm why would you think largest needed is (-240,4,255) ?

that coordinate lies in chunk -15,15 @dense shoal

[dense shoal]

I forgot how coordinates worked. Lemme work this out and try again.

[regal dew]

I think the X,Z you showed are correct

but im not sure why you are adding 1 to the X

and subtracting 16 for the X with largest chunk coord

[dense shoal]

OK, so math aside, I'm doing this
16 * CHUNK + 15 for the larger number chunk
16 * CHUNK for the smaller chunk

Where chunk is the chunk coords

[regal dew]

yea

thats fine

[fallen sparrow]

I'm creating a custom crafting plugin with a custom inventory, but I need to check when an item is added to the crafting menu. What Inventory event triggers when an item is moved into an inventory, not clicked?

[quaint mantle]

InventoryDragEvent

or something like thattt

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/event/inventory/InventoryDragEvent.html

[fallen sparrow]

I already tried that

[quaint mantle]

appearently not correctly

[fallen sparrow]

that calls when the item is clicked not when it is placed

[quaint mantle]

what does that even mean

just scan for this https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/event/inventory/InventoryEvent.html

and run whatever check ur looking for

and broadcast what event it was

[fallen sparrow]

It calls when you pick the item out of your inventory, but not when you place it in the crafting inventory

[quaint mantle]

its just 4 lines of code

@EventHandler
public void inventoryEvent(InventoryEvent e){
    Bukkit.getServer().broadcastMessage(e.getEventName());
}

[fallen sparrow]

im pretty sure i already did that, but ill retry

Doesn't work

[quaint mantle]

then the event isnt handled by Spigot

because thats literally an InventoryEvent

so if it was, it'd had done something

[unkempt peak]

Deos your class implement Listener and is your event registered onEnable

[fallen sparrow]

ya, every thing works, except it doesnt update the recipe output when an item is taken out of the inventory or moved into it

[unkempt peak]

What are you trying to do

[fallen sparrow]

i think i got it.

nevermind don't got it

I want to run the function checkRecipeCompleted() when an item is moved into the inventory or out

Got it, i just had to schdule it a tick later, so i could get where it moved to

[quaint mantle]

explain to me how this is a development issue @sweet cradle

[nova grove]

How can I make a config.yml file for my plugin?

[quaint mantle]

by learning how to make spigot plugins

[frosty tinsel]

Or learn to google

[frosty tinsel]

https://lmgtfy.app/?q=creating+config+spigot

[stone sinew]

public void onEnable() {
    if(getConfig().getKeys(false).isEmpty())
        saveDefaultConfig();
    reloadConfig();

    getLogger().info(getConfig.getString("Path"));
}

[quaint mantle]

No just

public void onEnable() {
    saveDefaultConfig();
    reloadConfig();
    getLogger().info(getConfig.getString("Path"));
}

[stone sinew]

Does saveDefaultConfig() check the data now?

[safe flower]

Does org.bukkit.conversations.Conversation#begin() block until the conversation is over?

[quaint mantle]

inventory events can be tricky

as far as i know yeah you can do custom crafting and recipes

maybe its worthwhile on crafting events to listen to the itemstacks in the craft inventory

im fairly certain thats how it works (if thats what your goal is)

better than doing a scheduler imo ^

[tribal sparrow]

is there a way to get players to see skins without an issue on first join?
if you open minecraft, join the server all skins are default steve, but when moving away and back again sending the packets again when in range the skins show. Then if i disconnect again and connect (without closing mc) the skins load to the player perfectly using the same packets? i've tried with a delay on login, i've tried showing and hiding then showing again after 60 ticks nothing seems to work.

[solid cargo]

Hey how can i make the customly dropped item unpickable up

[opal juniper]

cancel the pickup event

[solid cargo]

Doesnt it cancel all books?

[opal juniper]

just check to see if the item is yours

using teh pdc or sommin

then cancel it

[solid cargo]

Make the item a meta?

[opal juniper]

mmm no i would use the pdc

?pdc

[undone axle]

https://www.spigotmc.org/threads/a-guide-to-1-14-persistentdataholder-api.371200/

[solid cargo]

If item.hasMeta blah blah blah

Ah ok

[waxen plinth]

You don't need to cancel pickup events

That's a waste of processor time

20 times per second per player nearby

Just set the pickup delay to int max

[solid cargo]

Its ror a friend showcase anyways

[solid cargo]

Ah ok

[waxen plinth]

Yeah this is still easier

Doesn't involve handling events to do it

[solid cargo]

Ok thanks!

[waxen plinth]

👍

[solid cargo]

And is there a way to make the item not like uh

Going in one chonk?

[opal juniper]

hmm i didn’t think of that

[opal juniper]

what’s a chonk lol

[solid cargo]

You know when you drop multiple of the same items

[opal juniper]

oh

[solid cargo]

It looks like 1 item

[opal juniper]

the stacking?

[solid cargo]

Ye

Lesson starting. Will answer in 40 minutes!

[opal juniper]

uh i mean idrk on this one

there is probably an event but there may also be another way

[waxen plinth]

It's not super simple to do

[waxen plinth]

If players drop a stack of an item you will have to manually sort them out into individual items

[tribal sparrow]

        ItemMeta meta = item.getItemMeta();
        meta.setDisplayName(new Random().nextInt(Integer.MAX_VALUE) + "");
        meta.setLore(Arrays.asList("COIN_ITEM", new Random().nextInt(Integer.MAX_VALUE) + ""));
        item.setItemMeta(meta);
        return item;
    }```
having a different display name or lore for the item will make it not go into one item

[waxen plinth]

To prevent them from merging you give them each a random UUID in their lore or PDC

I mean, a random number also works but is more likely to collide

You have to do this after the items are dropped

[tribal sparrow]

and on entityitempickup you could see if it has a display name and change it so when it's picked up it doesn't show the random number

[waxen plinth]

Yep, remove it on pickup

[tribal sparrow]

using pdc

[waxen plinth]

And if you want it to not despawn

Set age to int min

[copper dove]
