[quaint mantle]

from?

but java not help i know the baisics of programing

[tender shard]

iirc no

[glossy venture]

shit

its with constants

shti

shit

from stackoverflow

hopefully they implemented that by now

[tender shard]

well if you do sth like

static final int SIXTEEN = 16;
static final int EIGHT = 16 / 2;

then obviously it uses 8 directly.

If you do stuff like this however

static final int SIXTEEN = 16;

static int half(int num) { return num / 2; }

static final int EIGHT = half(SIXTEEN);

then it definitely can't optimize it to bitshifts because it wouldn't work for negative "num"s

[glossy venture]

but there are signed and unsigned bitshifts

i think signed works for both negative and positive

[tender shard]

hm no idea. but I wouldn't worry about it anyway. I mean how often are you ging to divide something? it's probably totally irrelevant for the overall performance in 99.999% of cases

[glossy venture]

well its every time for a chunk access

block access

[tender shard]

then it's totally unnecessary to worry about it at all imho

[glossy venture]

what

how

[rapid goblet]

Hello can anyone help me I have a server of spigot but after i updated the server to 1.19 it always shows (incomplete sets of tags received from the server) but my friends can join but I cant

[glossy venture]

it might happen a load per tick

[tender shard]

#help-server

[glossy venture]

i mean div is fast but id like to keep highest performance possible

yeah

[rapid goblet]

No one replies over there

[glossy venture]

bitshift works on negative numbers

[tender shard]

but in the wrong channel (this one) noone will reply as well

[rapid goblet]

😔

[glossy venture]

and its not that hard to implement in javac

whatever i might change laer

later

[tender shard]

normally your CPU will use bit shifting anyway if possible

[glossy venture]

that wold be greta

wodl

i tried to type my typo but i mistyped the typo

[tender shard]

I have just tried it a few hundred times for one million divions and one million bitshifts and it's basically the same time for bitshifting or division

[glossy venture]

ok

[tender shard]

sometimes bitshifting is a bit faster, sometimes division is a bit faster

[glossy venture]

nice

thanks

[tender shard]

np

[glossy venture]

i need to code chunk system to not have horrible performance

for custom blocks

[proper pawn]

anyone?

[humble tulip]

It's cuz of the new chat thing

[pastel juniper]

If I install a custom resource pack with custom fonts, I can for example use this command /tellraw ANFFGaming {"text":"\uE000"} to show the fonts in the chat. How can I do the same with the plugin???

[quaint mantle]

you can check tellraw's source code

and recreate it in your plugin

`

`
is there way to get string in string like f-string in python
python example:

avar = "some content"
print(f"> {avar}") 

output:

> some content

thanks ash

https://xperti.io/blogs/formatting-with-printf-in-java/

[quaint mantle]

thx i'll check it out

[tender shard]

        Player player = null;
        ComponentBuilder builder = new ComponentBuilder();
        TextComponent component = new TextComponent("My text");
        component.setFont("fontname");
        builder.append(component);
        player.spigot().sendMessage(builder.create());

[pastel juniper]

Ty, I ll go to try it now

[native falcon]

hi, how do I make it so my plugin loads after every world has been loaded?

[sterile token]

Doesnt apply PostWorld?

[native falcon]

Doesn't work nope

[sterile token]

load: POSTWORLD

Like that it was cold

[native falcon]

yeah I tried that, doesn't work..

[covert karma]

how do i check if a player is inside lava? similar to player.isInWater()
the problem with checking the block at player position is that the player can stand mostly on one block but still touch the lava to the side

[native falcon]

yeah I already tested it, it's actually always POSTWORLD when you don't specify anything

[vast raven]

If I declare a variable, will it be deleted after the execution of the last line of code of a class, or until the server restarts?

[tender shard]

well if you censor the most important part, noone can help

[tender shard]

?learnjava

[undone axle]

Here are some links to get you started on learning Java:

• https://www.codecademy.com/learn/learn-java
• https://www.sololearn.com/learning/1068
• https://www.learnjavaonline.org/
• https://programmingbydoing.com/
• https://docs.oracle.com/javase/tutorial/java/index.html

The last one is the only official one, however some of those concepts assume that you already know a bit about programming.

[tender shard]

you should learn about "variable scope" and the difference between instance, class and local variables

[vast raven]

Actually, I know the concept, I don't know if in Spigot, will be the same, in theory if the var. isn't stored in the a persistent data place, you loose that after the restart.

[river oracle]

Java's Garbage Collector managers what vars stay around and which ones are cleaned up

You don't have to worry about manually managing that

When the plugin disables you lose all vars the same as any other program. If you close the program its nolonger going to be holding onto any memory. So again like any other java program if the plugin is disabled ofcourse the variables will be gone. If you want stuff to stick around use a database or if its small identifiers use PersistentDataContainers

[late sonnet]

i think only need the warden turn...

[echo basalt]

I heard that the warden is a pain to modify

let's hope it's not ender dragon levels of pain

[late sonnet]

not sure.. i mean i dont usually work with BehaviorController and this things...

[echo basalt]

mm behaviorcontroller I see

imma run buildtools and have a look

[late sonnet]

yeah im try to make a method to force the attack for my PR for methods in Warden

[echo basalt]

I feel like mojang will make all new mobs just use BehaviorController instead of pathfindergoals

might just be a new dev tasked with all of this tbh

[vital trout]

Hi guys, I want to make a team system in which players on the same team can see each other with a glowing effect, but I don't want the other teams to see this effect. After some research it seems that I need to use packets but I do not handle them very well actually, anyone got a hint/a piece of code/a link to help me out ? mc version : 1.18.2

[echo basalt]

glowing is done via entity metadata

or the glowing potion effect but that's kinda meh

you can use GlowAPI if you really need to

[vital trout]

Yeah but GlowAPI relies on PacketListenerAPI and it's not updated for 1.18 yet :(

[echo basalt]

I have a version that works for ProtocolLib

doesn't handle colors tho

[vital trout]

Just a white glowing ?

[echo basalt]

yep

[vital trout]

Well a solution with all the colors would be better if someone else know a way to do it

[echo basalt]

uhhh

you can do the bukkit team stuff and it should work on top

[latent heron]

anyone know what plugin could possibly be adding $100 to everyone's account every 100 seconds because it's so annoying and we can't figure it out?

[echo basalt]

TimeIsMoney?

[latent heron]

thats the thing I don't have that installed lol so idk what it could possibly be

[echo basalt]

or anything that runs commands on a timer

[clever musk]

What was FriendlyByteBuf called in 1.16.5?

[vital trout]

oh that would do the trick

[echo basalt]

welp here's the uh

unpleasant code I wrote like a year ago

[vital trout]

thanks c:

I just need to import protocollib to my project ?

[golden kelp]

why are you using Object

[echo basalt]

it accepts both NMS and bukkit entities and I can't bother making the same method twice

or couldn't, at the time

[golden kelp]

generics cry in the corner

[echo basalt]

yessir

[golden kelp]

xd

[echo basalt]

also it allows multiple data types and handles them separately

so yeah

[golden kelp]

oh thats sad

[echo basalt]

metadata packets are pain

this was the simplest way

[golden kelp]

i dont even know what those are 😂

[vital trout]

ok i'll try that later and I'll let you know ^^

[echo basalt]

TL;DR - it would suck to make an individual method for each data type

[golden kelp]

fr

[whole elbow]

How can i use colored arguments in a command with bridadier?
https://i.imgur.com/O7cTEtw.png

[lavish folio]

event.getEntity().getWorld().createExplosion(event.getEntity().getLocation(), 6f, false, false, event.getEntity());

6f is power and power is explosion strenght?

[echo basalt]

yes

it handles block damage and entity damage

6f is wither explosion iirc

tnt is a 4

[lavish folio]

https://minecraft.fandom.com/wiki/Explosion#Explosion_strength - wither is 8?

[echo basalt]

welp ig I'm an idiot then

[coarse finch]

what does this mean and how do i fix it

its for Player not block btw

[lavish folio]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/player/PlayerBedLeaveEvent.html use this as argument

public void functionName(PlayerBedLeaveEvent event) {}

[coarse finch]

oh thanks

[mellow edge]

working with minecraft client is defenetly harder than with server

[lavish folio]

yes

[compact cape]

Huh, why Statistic.PLAY_ONE_MINUTE returns ticks???

[tall dragon]

because someone in the development team forgot to take their brain with them that day

[tender shard]

what is that even supposed to return

[tall dragon]

playtime

[tender shard]

like why is it called ONE minute

why isn't it just called PLAYTIME

[tall dragon]

^

[tender shard]

yeah but

[compact cape]

EXACTLY 🤷

[tender shard]

even if it would return minutes

why would it be called ONE minute

[tall dragon]

yea idk

[proper notch]

fun tidbit, it used to be called play_one_tick, not play_one_minute

[tall dragon]

but it returns playtime in ticks

[tender shard]

all those statistics have those shitty names

FLY_ONE_CM instead of FLY_CM or FLY_CENTIMETERS

[tall dragon]

yea its very weird

[tender shard]

like noone would store the amount of TWO minutes played

[compact cape]

I don't mind the shitty name, At least put the ****ing right messure

[tender shard]

int playtimeInMinutes = getStatistic(PLAY_TWO_MINUTES) * 2
lmao wtf

so stupid

[warm light]

I want to make a logger plugin for all events. is there any easy way or I have to right all events?

[tall dragon]

you want to listen to all events?

[warm light]

Yes

[tall dragon]

well the only way to do that is to do some reflection magic

https://www.spigotmc.org/threads/listening-to-all-events-listing-all-events.337466/ heres some information about that

[warm light]

Alright. thanks

[tender shard]

logging ALL events? oh boy you're gonna have a bad time

[flint coyote]

because you completed "play one minute" for x times. So it kinda would make sense. But not in ticks

[tender shard]

BlockPhysicsEvent, RedstoneEvent, ...

[tall dragon]

PlayerMoveEvent 😄

those logs are going to be spammed hard

[tender shard]

yeah

you should definitely have a blacklist for certain events

[warm light]

umm, I just found it

[golden kelp]

YES, I remember how big of a pain forge was

[mellow edge]

I don't use forge

[humble tulip]

BlockPhysicsEvent

[mellow edge]

I have optifine

[humble tulip]

That's even worse

[mellow edge]

so bassiclly decompiled minecraft client

[quaint mantle]

Im thinking of disabling some of the particle affects done by the warden when sonic booming, however i've never dived this deep into the spigot api so any suggestions on where to start? I've heard it may be something to do with packets

[dark arrow]

I know I have asked the question the 100th time but I think I have to ask again ,How to remove a goal from an entity

[pastel juniper]

How can I send to different clickable messages in one chat line???

[dark arrow]

you can use bungee chat api

[dark arrow]

so what do you wanna know?

[humble tulip]

Sammu I'm not at my computer rn but is there a way to get the goals?

[tender shard]

I told you to use a ComponentBuilder

[dark arrow]

?

I cant you new goals and edit it

[dark arrow]

this.targetSelector.addGoal(3, new NearestAttackableTargetGoal(this, Pig.class, true));

I saw a method to get list but it was 5 years old and not working

[humble tulip]

U need tognet the goals by reflection or if there is a method

U can't remove a "new" goal since you're creating a goal that the enitity doesn't have

[coarse finch]

can i block the player from executing any commands?

[dark arrow]

what's togent?

[pastel juniper]

It worked, I forgot to add sth

[humble tulip]

Get the goal that you want to remove from the entity then remove it

[humble tulip]

To get *

[polar pagoda]

HidePlayer

[dark arrow]

ohk

[dark arrow]

thats was the main reason why i asked

i was getting confused on how can i get it

[humble tulip]

Look in the entity class and see if there's a method that returns the goals

Or if there's a feild with the goals

Or whatever targetselector is

[dark arrow]

there are many methos but i suspect addBehaviourGoals

[humble tulip]

This is to register the initial goals im pretty sure

[dark arrow]

here all the goals are added

[dark arrow]

yah

i cant find any reutrn

[coarse finch]

can i block the player from executing any commands?

[dark arrow]

i think i need to check more properly

[humble tulip]

See where the goals are stored from adding

[humble tulip]

Playercommandpreprocessevent

[coarse finch]

thanks

[dark arrow]

there is a register goal but i dont think it gonna work

[humble tulip]

See how goals are registered and u can figure how to unregister

What is targetselector?

[dark arrow]

the this.addBehaviourGoals

and some other goals are registered like that to

[humble tulip]

Yes i know but look deeper than that

See what that method does and the methods inside that method as well

Playing around with nms requires alot of digging around since it's undocumented

[dark arrow]

this.goalSelector.removeGoal(this.breakDoorGoal);

[humble tulip]

Wait it's a custom entity?

Just store the goals and remove it

[tender shard]

don't give the player the permission, remove the command from the command map, or cancel the CommandPreprocessEvent

[humble tulip]

U don't even need to look thru a list of goals then

[dark arrow]

Thats what i am saying form the starting

[tardy delta]

Van you write lambdas for abstract classes?

Can

[dark arrow]

.

[humble tulip]

I didn't know it was a custom entity

[dark arrow]

oh

i think i forgot to mention

[humble tulip]

Just store the goals in your customentity class

So u can remove them anytime

[tender shard]

wdym?

[tardy delta]

Overriding abstract method of abstract class

[tender shard]

you can use lambdas for functional interfaces

public interface MyInterface {

    void apply();

    MyInterface SOME_IMPLEMENTATION = () -> System.out.println("Nothing");
}

[tardy delta]

It has only one

[tender shard]

okay than you have to annotate it with FunctionalInterface

one sec let me check my update checker, it uses sth similar

[dark arrow]

I already found a mthod to do it but it gives out an internal error

[tardy delta]

Trying to use the java.util.logging.Formatter as lambda

[tender shard]

ah no it must be an interface @tardy delta

[tardy delta]

Ah sad

[humble tulip]

Can't help then

I'll be able to when I'm home tonight

[dark arrow]

ok

[coarse finch]

can i have multiple commands in the same class

[tall dragon]

yes

but i cant advize it

[coarse finch]

ok well then how can i access a hashmap from one command class in another

[tall dragon]

?di

[undone axle]

Guide to dependency injection: https://www.spigotmc.org/wiki/using-dependency-injection/

[tardy delta]

what was i doing lol

[polar pagoda]

can someone help me in my thread?

[tardy delta]

else try {} 😢

[mighty pier]

what does just static{} mean?

friend gave me this code

[tardy delta]

that it is doing those things when the class gets initialized

[tall dragon]

static means its constant through instances of the class

[tardy delta]

so same time when static variables are instialized

[mighty pier]

https://media.discordapp.net/attachments/718804796412264508/930441959963787294/709996427048124446.gif

[tender shard]

yeah as others said it's run when the class gets initialized. you can do it to run code related to your static fields like this

public class WhatEver {

    private static final Set<Material> ALL_SHOVELS = new HashSet<>();
    
    static {
        Arrays.stream(Material.values())
                .filter(mat -> mat.name().endsWith("_SHOVEL"))
                .forEach(ALL_SHOVELS::add);
    }
}

[ivory sleet]

static { } is a constructor but for static stuff only runs once

[humble tulip]

Have a class just to handle the hashmap

?di

[undone axle]

Guide to dependency injection: https://www.spigotmc.org/wiki/using-dependency-injection/

[humble tulip]

And have a getter for an instace of that class in your main class

And use dependency injection to pass your plugin to the command classes

[tardy delta]

wut

cant they be abstract?

[glass mauve]

It’s a record

[tender shard]

no, records are final

[tardy delta]

smh

[tender shard]

why do you need an abstract record?

[tardy delta]

i could just transform 20 lines to 3 lines but java was like no

[humble tulip]

Isn't a record a data class

Why u wanna use a record for a command?

[glass mauve]

Yea

[misty current]

can anyone help me with a design choice? I'm making a plugin and I am making wrapper classes for different types of items (enchantable items, ability items, consumables, etc.) and i want each one of them to have a static method to check if the itemstack you provide is that type of item (example, if the item has a certain nbt tag it will be a consumable). Any suggestions for a design i could use?

[ivory sleet]

What have you got so far?

[coarse finch]

i think i messed up the di ```java
private final HashMap<UUID, Boolean> frozenDict;

public UnfreezeCommand(HashMap<UUID, Boolean> frozenDict) {
this.frozenDict = frozenDict;
}```

[misty current]

i have an abstract class with a basic validator (checks if the item is not null or air) and i was making a registry class with all the wrapper classes in a list

[misty current]

something i thought of is making the constructor throw exceptions if the item argument is invalid and making a method in the registry class that tries to construct with reflections the class and catches exceptions to tell if the item is valid or not

[humble tulip]

Ah

Put the map in your main class

[coarse finch]

oh ok

[humble tulip]

And then inbthe brackets of ()

Put the map variable

So u give the map to your command

Don't change anything you had already

[coarse finch]

ok

[humble tulip]

Why does the method have to be static, won't you have one instace of the item class for each item?

[ivory sleet]

Sounds good kill05

[humble tulip]

Just makenit abstract

[ivory sleet]

Remember the direct values of your registries can always be facades providing access to your factories, observers and what not

[misty current]

what do you mean?

[ivory sleet]

Ugh, do you know any design patterns? 😅

[misty current]

kind of, yea

what do you mean with facades

[tender shard]

https://www.baeldung.com/java-facade-pattern

[ivory sleet]

^

[misty current]

i should've googled it, right :p

[coarse finch]

umm Caused by: java.lang.ArrayIndexOutOfBoundsException: Index 1 out of bounds for length 1

[tender shard]

array indexes start at 0

[coarse finch]

oh yeh

[tender shard]

your array has only one element so only array[0] exists

[coarse finch]

my brain is not functioning lol

[humble tulip]

I used this without even knowing it had a name

[misty current]

oh so that's called a facade

i kind of do it all the time

[humble tulip]

Same lol

[tender shard]

yeah it's probably the most vague of all design patterns lol

[ivory sleet]

Yes kill05 the most generic design pattern in Java in principle but it’s good to have formal names for all of these patterns, makes it easier to talk about design on a higher level

[tender shard]

one could say "it's an object that combines other objects and how they work together" lol

[crude cobalt]

Can I pass a global variable from one plugin to another?

[humble tulip]

U can

[misty current]

yup i agree

i often find naming classes problematic

[crude cobalt]

How?

[golden turret]

is Player#setWalkSpeed thread safe?

[coarse finch]

i missed one of the args[1] >:(

[humble tulip]

Well it depends

But u can

[misty current]

because i don't know how to express what does the class do

[golden turret]

also, is Inventory#getItem thread safe?

[humble tulip]

No

Bukkit stuff aren't thread safe

[torn shuttle]

quick question, does the player persistent data container survive restarts?

[humble tulip]

Yes

[torn shuttle]

thanks

[misty current]

why do you need to access an inventory from another thread

[river oracle]

There is no reason to multi-thread inventory access

[misty current]

it's not an expensive operation

[river oracle]

The rule generally is bukkit stuff isn't going to be thread-safe\

[crude cobalt]

I want to pass Hashmap. Any ideas how?

[misty current]

dependency injection

[river oracle]

Pass it as a parameter in a consturctor or method

[humble tulip]

Yeah innthe constructor

?di

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

[coarse finch]

what is vanilla walkspeed

[misty current]

anyways back to what i was saying, this is the abstract wrapper class https://paste.md-5.net/beromunuhu.java

[frozen star]

1

[coarse finch]

thanks

[misty current]

and the child classes will implement the isValid method

if the isValid method returns false for an item, the constructor will throw an exception

[ivory sleet]

Read access more or less so

But frequent read writes will not be thread safe by any means

kill05 why does it need to throw an exception?

[frozen star]

i'm trying to figure out how to make a player look at an entity (trying to make a diologue thing) and i am having trouble with vectors. here is my code https://paste.md-5.net/kekuyovoco.cs
and i think the main problem is the error on line 6

idk how to get the .subtract to work

[coarse finch]

woah, 1 is way too fast

[frozen star]

try 0.1 then

it might be 10% of what i said

1 might be 10 to essentials

[coarse finch]

its .2

[misty current]

so if i ever try to wrap the wrong item i will know before i start getting exceptions later on

[frozen star]

interesting

[coarse finch]

well according to google its .2

[misty current]

and also so i don't write illegal data to an item's nbt

because let's say i try to wrap a consumable as an enchanted item by mistake and i don't notice

and then i try to enchant the item, the consumable will have illegal data on it

[misty current]

iirc yep that's the value

[ivory sleet]

Hmm okay I would null return or use Optional upon invalid conversion

[midnight quarry]

I am trying to use Fast Async World Edit API in my code, but when I try to install it through maven and write some code, upon compilation it says it cannot access some classes?

cannot access com.sk89q.worldedit.bukkit.BukkitAdapter

[nova sparrow]

How would you start a raid wave through spigot?

[tardy delta]

should i use DateTimeFormatter or is there a newer class?

[misty current]

I'm directly using the constructors to create the wrappers, but if I made a factory class i could do that

[ivory sleet]

Yes almost always use factory methods or classes

It’s a so easy yet powerful way to decouple creation and instantiation

[misty current]

can I make the factory into a singleton or is that bad design?

i'm pretty sure i would start getting annoyed by having to dependency inject my factory instance everywhere

[humble tulip]

Why wpuld you need the factory everywhere?

[crisp steeple]

static/singleton is usually fine for a factory

[humble tulip]

But ye

Esp if u want other plugins to hook

[misty current]

because i would need the wrappers very often

[humble tulip]

Ah ok

[misty current]

anything i do related to items/entities will be done trough the wrappers

tryna experiment different designs to see what i am comfortable with

[opal carbon]

is there somewhere online with some sorta javadocs for Mojang mappings

so I can actually find classes and methods for stuff yaknow

and also I assume that if I want to use Mojang mappings I will have to use that maven plugin that has been included in the dev section of update logs since 1.17

[ivory sleet]

Or paperweight

[iron glade]

Does anyone know a sound that sounds like turning a page or some sort of short "clicky" sound?

[ivory sleet]

(Gradle)

[opal carbon]

I mean isnt there book and quills/ lectern sounds for pages

[tardy delta]

i guess there is a better way lol

[tall dragon]

UI_BUTTON_CLICK is a pretty nice one

[humble tulip]

Book turn page sound

[vocal pine]

how do i retrieve an actual entitytype from the registry (my custom entity) to use in it's constructor for an item spawn

[humble tulip]

ITEM_BOOK_PAGE_TURN

[vocal pine]

Registry.ENTITY_TYPE.get(keyThing) returns capture but i need the entitytype itself and i'm not smart enough for that

[humble tulip]

@iron glade ^^

[fringe hemlock]

Hi y’all, is there anyway to modify a particle packet to make the particle stay visible longer? From what I read it’s hard coded but I just want to make sure

[misty current]

i'm pretty sure the client handles the duration of particles

[fringe hemlock]

That sucks, thank you though! :)

[opal carbon]

you could just try making another particle

            e.printStackTrace();

            return o;
        }


        return o;
    }

This code is suppose to get the list of the goals of my custom entity and clear it but instead it gives internal error

[tardy delta]

returning o in any case /shrug

How do i parse urls in java? I need to parse mongo and redis url

[humble tulip]

It's final

[sacred mountain]

hey

im finally alive

[sterile token]

Light furry nice to see you again

How are you?

[dark arrow]

what final?

[humble tulip]

U can't set it cuz it's final

https://stackoverflow.com/questions/3301635/change-private-static-final-field-using-java-reflection

[dark arrow]

so that means there is no hope now?

[humble tulip]

I feel like you're going about this the wrong way

You can set a field to no longer be final

[dark arrow]

i mean the file is read-only

oh

got it

[sterile token]

Minion, do you know how i can parse url like does mongo or redis?

[upper vale]

What?

[sterile token]

Yeah let say i have the url: "mongodb://username:password@host:port/route"

[upper vale]

I don’t understand what you mean by “parse” it?

I mean Mongo and redis allows you to connect via a URI directly afaik

You don’t need to parse it and extract the credentials yourself

[sterile token]

Im needing to find a way of reading let say the hot, port, etc

I know i just want to design my own url that why

[royal grove]

hi i have a question i wanna make soemthing when you shoot an arrw the console sends a message tot that player with the cordinates of that arrow

[upper vale]

This would be helpful https://docs.oracle.com/javase/7/docs/api/java/net/URI.html

[sterile token]

Oh thanks, im using that but i cannot find the method for parsing the password

[quaint mantle]

//dont actually use
int separator = input.indexOf("://");
String dbProvider = input.subString(separator);

int colon = input.indexOf(":");
String username = input.subString(separator, colon);

int at = input.indexOf(...)

[sterile token]

Ohh ok

Thanks imagin i will try

[quaint mantle]

but you should use

https://docs.oracle.com/javase/7/docs/api/java/net/URI.html

new URI(input)

[sterile token]

Allright

[quaint mantle]

does all of it for you

[sterile token]

Thi should be for parsing password and username rigt?

Thanks to the too of you

[quaint mantle]

no dont

it does it for you

[scheme:][//authority][path][?query][#fragment]

[sterile token]

Ohh ok

I just catch it

[tender shard]

listen to ProjectileHitEvent, get the shooter of the arrow, then send a message

[sterile token]

mfalex, is open source your http client?

[royal grove]

can you maybe send a ittle bit of a beginning code becouse im not new but wanna learn more about java

[tender shard]

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

[royal grove]

thx

[sterile token]

Imagin so:

URI bla = URI.create("custom://username:password@host:port");

String[] auth = bla.getUserInfo().split(":");
String user = auth[0];
String pass = auth[1];

[quaint mantle]

do you ever listen to what i say

like not even being mean

i dont even think you need the username:password

well

i think authority takes that in

so you dont have to worry about that

no need to split anything

[sterile token]

Hmn i dont know tho

There is no URi getter which returns a the password

[quaint mantle]

kms

[sterile token]

"user:pass@localhost:6379" that what return getAuthority()

[quaint mantle]

weird

[sterile token]

Yes

I was listening to you, but the method doesnt return what i expect

[vocal pine]

How do I change network ID of an entity ideally without ProtocolLib? I just want to make my custom entity a different entity to clients but I can't find anything on this specific topic

[tender shard]

the "authority" is the full string

[vocal pine]

Nor can I find anything in NMS itself about it

[tender shard]

without the path

[vocal pine]

Probably just bad at looking but if someone can point me at where to look in NMS to learn I'd appreciate it

[tender shard]

        URI uri = URI.create("custom://username:[e-mail]:25565/location");
        System.out.println("Authority: " + uri.getAuthority());
        System.out.println("Path: " + uri.getPath());
        System.out.println("Host: " + uri.getHost());
        System.out.println("Port: " + uri.getPort());
        System.out.println("UserInfo: " + uri.getUserInfo());

this prints out this:

Authority: username:[e-mail]:25565
Path: /location
Fragment: null
Host: jeff-media.com
Port: 25565
UserInfo: username:password

[sterile token]

Allright

[tender shard]

you'd have to listen to outgoing packets. why do you want to change the ID in the first place?

[sterile token]

mfalex, also client can display non minecraft entity?

[vocal pine]

because i'm stupid is probably the main reason

i was able to register my entity so I thought hey, why not just pass that to superconstructor

means it saves, reloads, loads, etc. all perfectly fine without janky workarounds like changing the ID on save

i know the normal way to do things is pass a different entitytype to superconstructor (matching the class it extends) so it shows like that to clients

but i didn't like the janky workarounds purely subjectively so i thought i'd make things harder for myself

👍

[tender shard]

idk probably you'll get an error message like "unknown entity type" on the client

[vocal pine]

just shows as a pig

[tender shard]

oh or that

[vocal pine]

yup

[tender shard]

it's weird that pig is the default entity lol

[tender pond]

Hey guys! Was just wondering if anyone could help me with this...

So I'm using the InventoryClickEvent alongside a InventoryType.ANVIL Inventory Menu.

The inventory is opening all fine, but I'm basically struggling with getting the Display Name of the item in the 3rd Slot, e.g. the final slot. However when trying to print out the DisplayName value it is returning the original name of the item in that slot. Also to clarify, I am setting a NameTag to both Slot 0 and Slot 2 with the name "Rename Me" and when printing out the value even after changing it in the Anvil GUI it is returning "Rename Me".

if (i.getView().getTitle().equalsIgnoreCase("Alliance Creation")) {
            if (i.getSlotType() == InventoryType.SlotType.RESULT) {
                Bukkit.broadcastMessage(i.getCurrentItem().getItemMeta().getDisplayName());
                i.setCancelled(true);
                player.closeInventory();
                gui.add(player);
            }else{
                i.setCancelled(true);
            }
        }
``` here's the code alongside a few screenshots

[vocal pine]

it's pretty cool imo

riding pigs around railways

[vocal pine]

im assuming for specifically a minecart from the packet list i'm reading - i need to modify Entity Spawn and Passenger packets but everything else should be fine?

[tender shard]

I have no idea, as said I never really did any custom entities

[tender shard]

I don't really understand the problem you're having

pls try again to explain

1. what you want to do
2. what happens instead

[tender pond]

So as you can see in the screenshot. I basically want to get the DisplayName of the item after I click the 3rd slot, however, it is instead just returning the default name which is just "rename me"

[sterile token]

I endup with this code, if someone want to do something similar in the future then you can use it

URI uri = URI.create("scheme://user:pass@localhost:6379/db-name");

System.out.println("Scheme: " + uri.getScheme());
System.out.println("Host: " + uri.getHost());
System.out.println("Port: " + uri.getPort());
System.out.println("Username: " + uri.getUserInfo().split(":")[0]);
System.out.println("Password: " + uri.getUserInfo().split(":")[1]);
System.out.println("Database: " + uri.getPath().split("/")[1]);

[tender pond]

1. I want to retrieve the DisplayName of the item in the 3rd Slot after changing it via the Anvil GUI.
2. When retrieving the DisplayName of the item in the 3rd Slot it is receiving the DisplayName "Rename Me" rather than the Display Name "Rename Medasd" as seen in the Screenshot. So basically it appears the event isn't updating the item meta as I'm changing it simultaneously in the GUI

Hopefully that makes sense

[tender shard]

yeah that makes sense. Hm can you send your current code? Because that should work fine from what I guess

the full code of your listener

[vocal pine]

ah ty sorry

[tender pond]

Inventory inv = Bukkit.createInventory(null, InventoryType.ANVIL, "Alliance Creation");
                            ItemStack invitem = new ItemStack(Material.NAME_TAG);
                            ItemMeta meta = invitem.getItemMeta();
                            meta.setDisplayName("Rename Me");
                            invitem.setItemMeta(meta);
                            inv.setItem(0, invitem);
                            inv.setItem(2, invitem);
                            player.openInventory(inv);
``` here's the command to open the GUI

if (i.getView().getTitle().equalsIgnoreCase("Alliance Creation")) {
            if (i.getSlotType() == InventoryType.SlotType.RESULT) {
                Bukkit.broadcastMessage(i.getCurrentItem().getItemMeta().getDisplayName());
                i.setCancelled(true);
                player.closeInventory();
                gui.add(player);
            }else{
                i.setCancelled(true);
            }
        }

Here's the InventoryClickEvent

[tender shard]

what is "i"?

oh

the event

that's a weird name for an event lol

[tender pond]

Yeah lol 😄 Usually I do 'E' instead of 'I' but because it's to-do with Inventory I did 'I' lol

[tardy delta]

not even e

[tender shard]

no idea, from what I see it should be working fine. might have something to do with the fact that you set both slots to the same item. try to do

inv.setItem(2, invitem.clone());

[sterile token]

Also, when asking for support always send full code

[tardy delta]

why having to clone the item again?

[tender pond]

Unfortunately the same thing

[tender shard]

okay let me try sth

[tender pond]

Because if I only set it to the first slot, when clicking the 3rd Slot it returns the item as null

So something funky is happening 😄

[prisma steeple]

hi there

I'm very new to this and i'm trying to understand how things work, and i encountered my first "issue"

I'm pretty sure it's a logical error

 Integer XCoord = event.getBlock().getX();
            if(XCoord < 50){
                Player player = event.getPlayer();
                player.sendMessage("X = " + XCoord);

The intent = if a block is places when the x coordinate is above 50 it sends a message specifically to the player which states the X coordinate

however it won't seem to work, no errors

[sterile token]

Also dont use Integer, use int

[prisma steeple]

makes a difference ?

[tender pond]

Silly question, but have you registered the command/event

[sterile token]

its an event

[prisma steeple]

one moment

here

public void BlockPlaces(BlockPlaceEvent event){
        int XCoord = event.getBlock().getX();
            if(XCoord < 50){
                Player player = event.getPlayer();
                player.sendMessage("X = " + XCoord);
                
            }


    }

pretty much the full code

[sterile token]

That wrong

[prisma steeple]

except the class

[sterile token]

You are missing the annotation @EventHandler

[tender pond]

Do you have @EventHandler above that?

[prisma steeple]

No I do not

thank you

[sterile token]

That the reason

[prisma steeple]

I do that just by write @eventhandler ?

[sterile token]

@EventHandler

[prisma steeple]

thanks

[sterile token]

Like that using capitalls

[prisma steeple]

also if you don't mind me asking

whats the difference if I write Integer or Int

Honestly wrote it bc it was the thing that came up, not because I write integer

but nonetheless thanks :)

[sterile token]

int*

[prisma steeple]

int yes my bad

[tender shard]

you need an AnvilInventory. Unfortunately you cannot cast a custom inventory to an AnvilInventory. I'll look through some CraftBukkit classes to see if I find something

[tender pond]

Hmm interesting, thank you! All I basically wanted was the player to be able to name something via this GUI, as I'm pretty sure I've seen it in other plugins before. I really appreciate you for helping with this, let me know if you get it to work 🙂

[tender shard]

you can definitely do it with NMS but it's messy. I'm sure there must be another way

[tardy delta]

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

[tender pond]

https://github.com/WesJD/AnvilGUI

I found this, but couldn't figure out how to do it

[prisma steeple]

Thanks :)

[tender shard]

yeah that's simply using NMS

[tender shard]

are you using maven?

[orchid pollen]

does anybody know a good spigot tutorial for intelij for begginers

[flint coyote]

int is a primitive datatype and can only hold numbers
Integer is the corresponding class that can also hold null (not 0) values

That's also why you use it in maps and lists

[tender shard]

and for generics

[tender pond]

Yep I believe so. I managed to link into the API of AnvilGUI but couldn't figure out how to use it properly

[tender shard]

do you have a pom.xml file?

[tender pond]

Yep

[iron glade]

If you need help with AnvilGUI hit me up

[tender pond]

Oooh 👀

[tender pond]

.

[tender shard]

then you can add the the stuff mentioned in "Usage -> As a dependency" to your pom.xml, click the maven reload button, and then mess around with the AnvilGUI.Builder to build your custom anvil inv

[prisma steeple]

eh- my code still seems to not be working

[tender pond]

I should use the AnvilGUI.Builder in my Command Class right?

[tender shard]

yeah

[prisma steeple]

just like before, nothing happens

[tender shard]

and then you can provide a BiFunction to the onComplete method

[prisma steeple]

full code

oh

oh

wait

nevermind

[iron glade]

why is the @EventHandler so far away from the Event xD

[sterile token]

 @EventHandler
    public void BlockPlaces(BlockPlaceEvent event){
        int XCoord = event.getBlock().getX();
            if(XCoord < 50){
                Player player = event.getPlayer();
                player.sendMessage("X = " + XCoord);
            }
    }

[prisma steeple]

i have no idea, i will arrange it

[iron glade]

not that it would change anything

but looked funny

[sterile token]

Out what the issue?

[crisp steeple]

did you register the event

[sterile token]

Alo outlet did you learn how works the api?

I think the main issue

[prisma steeple]

the main issue is me not exactly knowing how it works if anything

However i don't see anything wrong with this code

[iron glade]

Which code?

[prisma steeple]

I feel not enough

package com.outletserver;

import org.bukkit.Bukkit;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;

import org.bukkit.event.block.BlockPlaceEvent;



public class ChunkLoad implements Listener {
    @EventHandler
    public void BlockPlaces(BlockPlaceEvent event){
        int XCoord = event.getBlock().getX();
            if(XCoord < 50){
                Player player = event.getPlayer();
                player.sendMessage("X = " + XCoord);
                
            }


    }
}

this code

this is not working

it should work

[tender shard]

oh wait, it seems like the AnvilGUI doesn't even have a method to set the result item lol

[prisma steeple]

I am at X27 placing a grass block

[iron glade]

show your onEnable in your main class

[iron glade]

yes

[tardy delta]

method names start with a lowercase letter smh

[tender shard]

yeah that's unfortunate

[iron glade]

that's the one thing that annoyed me like hell

[sterile token]

I know

Jut copy-paste what he ent

[tardy delta]

then do it >-<

[sterile token]

Its not my event

[tender pond]

Oh... ermmm

[sterile token]

Its him/her even t

[iron glade]

his/her*

[crisp steeple]

did you register the listener in your onEnable

[sterile token]

Yes sir, soy español that the problem

[iron glade]

pas de probleme mon ami

[sterile token]

Haha no problem

[tender shard]

I think sth like this should work

    @Override
    public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
        ItemStack myNametag = new ItemStack(Material.NAME_TAG);
        ItemMeta meta = myNametag.getItemMeta();
        meta.setDisplayName("Rename me");
        myNametag.setItemMeta(meta);
        new AnvilGUI.Builder()
                .itemLeft(myNametag)
                .plugin(this)
                .onComplete((player, name) -> {
                    Bukkit.broadcastMessage(name);
                    return AnvilGUI.Response.close();
                }).open((Player) sender);
        return true;
    }

[prisma steeple]

yes, i think i did it well

hold on

        public void onEnable() {
            System.out.println("hi!");

            Bukkit.getPluginManager().registerEvents(new ChunkLoad(), this);

        }
        public void onDisable(){
            System.out.println("Server off");

        }
}

[iron glade]

@Override

should be above onEnable and onDisable

[tender shard]

(although not needed for it to work)

[iron glade]

yes

[prisma steeple]

what does override do

[crisp steeple]

is your plugin.yml setup properly?

[tender shard]

nothing, besides throwing a compile time error if you misspelt onEnable or whatever method you wanna override

[prisma steeple]

i mean, there isn't necessarily much supposed to be in there right?

main: com.outletserver.myfirstplugin
name: Plugin1

this is what is in there

[iron glade]

api version

api-version: *

[prisma steeple]

ahh okay

[iron glade]

what's your main class called?

[prisma steeple]

[iron glade]

okay

[tender shard]

that's a weird class name

[iron glade]

which version are you coding against?

[prisma steeple]

it's my first plugin

so i called it myfirstplugin

[prisma steeple]

wdym?

[tender shard]

you did not shade the anvil gui. it's explained on the github page in the "as dependency" section

or you didnt use maven to build your plugin

[iron glade]

API version.. like.. 1.18?

[prisma steeple]

OHH

my bad

1.17

[crisp steeple]

try just sending a message without any of the conditions just to make sure the listener is registered properly

[iron glade]

then add
api-version: 1.17

to your plugin.yml

[prisma steeple]

alright

i will do that too

[iron glade]

anything in the console when loading the plugin?

[prisma steeple]

it literallytold me what you told me to do

"did not specify API version"

should've read the console

[tender shard]

that's no problem

it would still work

that's just a warning to inform you that your plugin is the reason for legacy material support being enabled

[tender pond]

Just tried to shade it, still didn't work unfortunately. I'm pretty sure I'm using maven to build it? How do I check just to make sure

[prisma steeple]

m, makes sense

[tender shard]

what do you do to compile the plugin?

[prisma steeple]

so if i specify it won't need to enable it

[iron glade]

anything else in the console @prisma steeple

[prisma steeple]

uh

[tender pond]

Build -> Build Artifacts -> Build

[prisma steeple]

The

[iron glade]

iirc it enables it if your plugin is < 1.13

[prisma steeple]

@tender pond

[cerulean charm]

Hello there! Im kinda new in the spigot plugin development.
I have a problem with detecting a player right clicked another player with a specific item.

I know the two events PlayerInteractEvent, PlayerInteractEntityEvent but i dont know how to link them each other.

public void onPlayerSelect(PlayerInteractEvent event, PlayerInteractEntityEvent e) {
        if (event.getAction().equals(Action.PHYSICAL) && event.getItem() != null && event.getItem().getItemMeta().equals(ItemManager.telegem.getItemMeta())) {...}

I tried this but I got an error
[22:06:13 ERROR]: [Hg-Core] Hg-Core vBeta-1.0.1 attempted to register an invalid EventHandler method signature "public void hu.hugaming.hgcore.events.teleportGem.onPlayerSelect(org.bukkit.event.player.PlayerInteractEvent,org.bukkit.event.player.PlayerInteractEntityEvent)" in class hu.hugaming.hgcore.events.teleportGem

[tender pond]

I actually did this initially but it's red, and it doesn't go away

[tender shard]

you cannot declare two events to listen to in one method

[tender shard]

maven-jar-plugin(!!)

[tender pond]

Even after Loading Maven Changes

[cerulean charm]

I know...

[tender shard]

now maven-compiler-plugin

[tender shard]

just create your own method where you pass the required arguments to

[iron glade]

Do I have to worry that I don't have a maven jar plugin in my pom?

[sterile token]

?learn-spigot-api momment!

[iron glade]

remove the 2nd

[sterile token]

On listener, 1 method listen to 1 event

[tender pond]

Ahh, I don't seem to have that in my Pom do I have to custom add it?

Nvm it says that on the Blog post

My bad

[tender shard]

public void myMethod(ItemStack item) {
...
}

@EventHandler
public void onFirstEvent(SomeEvent event) { myMethod(event.getItemStack()); }

@EventHandler
public void onAnotherEvent(AnotherEvent event) { myMethod(event.getItemStack()); }

you just add it to your <plugins> section

there's a thing called loadafter

[lean osprey]

no, thats loadbefore

explanation of softdepend: A list of plugins that are required for your plugin to have full functionality.

Your plugin will load after any plugins listed here.

But I dont really know why it doesnt work

this.blue = meta.getColor().getBlue();
```from a valid Potion ItemStack, why does this result in a nullptr error in the console log?

[delicate lynx]

which part

[humble tulip]

Does it have a color?

[granite owl]

PotionMeta.getColor() returns null

for some reason

[delicate lynx]

Plugins should check that hasColor() returns true before calling this method.

[granite owl]

but potions always have colors dont they

[delicate lynx]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/inventory/meta/PotionMeta.html#getColor()

apparently not

[granite owl]

where do vanilla potions get their color from then?

okayive just used hasColor

apparently vanilla potions have no color?

why not lol

[glossy venture]

how can i do something async, and then when its done doing the task have all data in the class be synchronized immediately

imagine if i have a class

class Data {
    boolean loadComplete;

    int x, y, z;

    void loadAsync() {
          threadPool.execute(() -> {
               // do some expensive loading task
               // now i want to synchronize all the data
               loadComplete ();
          });
    }

    synchronized void loadComplete() {
         loadComplete = true;
    }
}

[patent horizon]

how do i cast an integer to a double? blind casting isn't working

[tardy delta]

(double)

[patent horizon]

yea i tried that

[granite owl]

(double) urint

double d = (double) whatever

[patent horizon]

oh oops

i wasnt using primative

[granite owl]

u need to use the constructor if ur using complex classes

[tardy delta]

set the fields in the loadcomplete method i guess

[cerulean charm]

And what if i want to check them both? The player holding the item and right clicking onto the other player?

[glossy venture]

bruh but then the data is gone

i dont want to synchronize all accesses

[tardy delta]

what ¯_(ツ)_/¯

anyways if i wanted to get some annotation with #getAnnotation what retentionpolicy does it need to have?

CLASS i think

[prisma steeple]

 public void BlockPlaces(BlockPlaceEvent event) {
        Player player = event.getPlayer();

if i have this

and 2 people place a block

what happens

[tardy delta]

nothin

[prisma steeple]

oh

they are local to the player?

[tardy delta]

two different events are fired

[prisma steeple]

Ahh when you explain it like that it makes much more sense

[tardy delta]

that player variable refers to the player who played the block

[tender shard]

is that even annotated with EventHandler?

[tardy delta]

and will be executed for each blockplace

[prisma steeple]

Yes

[humble tulip]

It's also single threaded so 2 ppl can't place a block at once

[prisma steeple]

no i mean it when that variable is taken up

[humble tulip]

Ohhh

[prisma steeple]

and someone else places a block

[sterile token]

That what makes the game really laggy

[tender shard]

you can get the annotation from classes, methods and fields. The retentionpolicy has nothing to do with whether you can get it via reflection or not, or am I misunderstanding your question?

[prisma steeple]

yes

mojang noob

[tardy delta]

no i just started with this and im noob

[tender shard]

if a class is annotated, you can use Class#getAnnotations(). If a field is annotated, you can use Field#getAnnotations(), etc

[tardy delta]

ye but whats the retentionpolicy then?

[tender shard]

oh that's what you mean

[tardy delta]

"how long the annotations are to be retained" doesnt tell me much

[tender shard]

erm tbh not sure. SOURCE is definitely not visible anymore, I think for CLASS it's kinda unspecified. It simply says "need not be retained by the VM" but not that it will definitely discarded

[tender pond]

Hey guys can anyone help with this? I'm very confused... So I'm basically getting a string and sending it through this system, and just to confirm I'm posting the string to make sure it's 100% correct before this if statement.

So for some reason this is entering the if statement even when only using Letters and no numbers for some weird reason, and I have no clue why as I'm pretty sure the regex works

[tender shard]

I think to access them with reflection you definitely need RUNTIME

[sterile token]

Why using Bungeecord chat color?

[tardy delta]

lets find out

[tender pond]

Honestly not sure, it just tab completed into that 😄 I'll change now

[mighty pier]

is it possible to send the player turning red death animation when the player hasnt died?

[sterile token]

Allright, because that can cause issue

[prisma steeple]

how to get player XYZ levels

[tender pond]

Yep still not working unfortunately

[tardy delta]

i think i need runtime ye

[tender shard]

just use [a-zA-Z]

then it'll work

[tender pond]

Does that block special characters too though? Cause I need to block special characters

[tender shard]

it will only return true if the string consists of NOTHING besides normal a-z and A-Z

[tender pond]

Hmm... still nothing 😄

[tender shard]

        "2asd".matches("[a-zA-Z]+") -> false
        "öäü".matches("[a-zA-Z]+") -> false
        "asd".matches("[a-zA-Z]+") -> true

I just tested this

[tender pond]

Would including it in the AnvilGUI.Builder thing affect it?

Cause I'm basically including it under the .onComplete() thing

[sterile token]

Any simple code for genereting random codes with numbers and letters?

[tender shard]

it might contain color codes. print out the string or run it through ChatColor.stripColors

[tardy delta]

cast the return type of the random next int to a char and concatenate them or smth

[tender pond]

Yep I already am, it's coming out White

Will strip colors just to make sure though

[mighty pier]

bump

[tender pond]

Still not working

Omg I've just realised what caused it... spaces 😄

why do you use protocollib for that

RIP

https://helpch.at/docs/1.12.2/org/bukkit/event/server/ServerListPingEvent.html

it also exists in 1.12.2

you can

I know

that's from the 1.12.2 javadocs

ugh well this is from 1.19, I wonder why it exists if it's always just throwing an exception

very weird lol

[naive bolt]

its jeff media im in your server

Nice

[tardy delta]

all the Player.Spigot methods are throwing an unsupportedexception too arent they?

[tender shard]

me too lol

[tender shard]

nooo

Player.spigot() is for example to send basecomponent msgs

[late sonnet]

that method is overriden when is called in NMS

[tardy delta]

but they are implemented i guess

mmh

[late sonnet]

i remember when make the PR for support the hide player info for ping things...

[tender shard]

huh why so complicated

[late sonnet]

not sure why...
sounds confuse but that is how works..

[tender shard]

lmao that's really... weird

I'm sure there is SOME reason for this

[quaint mantle]

hey guys I've been struggling at finding a working answer on how to do tool durability

[tardy delta]

creating a class in a method brr

[tender shard]

cast the ItemMeta to Damageable, set the damage, then set back the itemmeta

[quaint mantle]

I tried

I don't know why it's red

[tender shard]

then hover over it and read it

[quaint mantle]

it cannot resolve the method

[tender shard]

which method?

[quaint mantle]

setDamage

[tender shard]

wrong import

you imported org.bukkit.entity.Damageable

but you have to import org.bukkit.inventory.meta.Damageable

[quaint mantle]

is this done correctly?

            ItemMeta tempPick = inHand.getItemMeta();
            (Damageable) tempPick.setDamage(tempPick.getDamage() - 1);
            inHand.setItemMeta(tempPick);```

[tender shard]

no, that's not even valid syntax

[tardy delta]

((Damageable)meta).setDamage

wait no

wait yes

its too late for me

[tender shard]

Damageable meta = (org.bukkit.inventory.meta.Damageable) inHand.getItemMeta();
meta.setDamage(meta.getDamage() - 1);
inHand.setItemMeta(meta);

[tardy delta]

i wanted to say that but my brain was like meh you need sleep

🤤

[quaint mantle]

when casting do I have to put the whole import?

[tardy delta]

na

[quaint mantle]

I imported it at the top

[tardy delta]

only make sure you got yhe right one

[quaint mantle]

it's this one :)

maybe I'm doing something wrong

instead of taking damage it just repairs the item?

[eternal oxide]

damage goes up not down. 0 = no damage

[quaint mantle]

so should I add instead of subtract?

[tardy delta]

setting a negative damage wouldnt make much sense for me

idk if it works like that but ye

[quaint mantle]

I want it to just be as if the pickaxe mined a block

but I have to cancel the event so it's not taking damage

ok it works

thank you guys

I just tested and it kind of works

it bypasses unbreaking enchants

[tender shard]

then you have to do sth more complicated

[quaint mantle]

how would I go about doing it?

[tender shard]

https://github.com/JEFF-Media-GbR/JeffLib/blob/860d7154df73d848840915e9e7cef765a403f5f0/core/src/main/java/de/jeff_media/jefflib/ItemStackUtils.java#L173

otherwise you'd be ignoring vanilla and/or custom enchantments, etc bla bla

[quaint mantle]

where is JeffLib.getRandom() defined?

[tender shard]

https://github.com/JEFF-Media-GbR/JeffLib/blob/860d7154df73d848840915e9e7cef765a403f5f0/core/src/main/java/de/jeff_media/jefflib/JeffLib.java#L84

it's just an instance of Random

just do ```java
private static final Random random = new Random();

[quaint mantle]

alright it works great

thanks again

[tender shard]

[quaint mantle]

[eternal oxide]

implement ConfigurationSerializable

and do everything its Javadoc says to do

[native nexus]

Or simple use gson

[eternal oxide]

gson will not serialize a Location

Both require additional steps to serialize

So just use teh one thats already coded for you in Bukkit

yes

[vocal pine]

was able to figure out stuff from earlier :) custom entity using its own id that client sees as a minecart 👍

just feels a bit less janky than the workarounds to respawn a custom entity
no idea if it's more practical or can do anything the ones using another's ID/EntityType cant

[eternal oxide]

if you correctly implemented CS and did as teh Javadoc says and register your Class.

In addition to implementing this interface, you must register the class with ConfigurationSerialization.registerClass(Class).

in your onEnable, or anywhere before you attempt to read from yrou config

nope

[tender shard]

better in onLoad. otherwise you'll get problems when the config gets loaded, because that happens before onEnable IIRC?

[eternal oxide]

that is the data you are going to build your object with

[eternal oxide]

yep

no

[tender shard]

public class Person implements ConfigurationSerializable {
    
    private final String name;
    private final int age;

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

    @Override
    public Map<String, Object> serialize() {
        Map<String,Object> map = new HashMap<>();
        map.put("name",name);
        map.put("age",age);
        return map;
    }
    
    public static Person deserialize(Map<String,Object> map) {
        String name = (String) map.get("name");
        int age = (int) map.get("age");
        return new Person(name, age);
    }
}

and in your onLoad:

ConfigurationSerialization.registerClass(Person.class);

[eternal oxide]

Location is already serializable so you can use map.put("location", location.serialize())

[tender shard]

you can also just put in the location directly

no need to call serialize

[eternal oxide]

um, true, it will be retained as an object and serialized when needed

[tender shard]

actually if you use serialize() yourself then it will be stored as map so you won't know what to deserialize it to again

because it will be missing the "==" field in the yaml or whereever it is stored

[eternal oxide]

oh yeah

[ivory sleet]

So quick question, does anyone here use sth like
(++i)++ as opposed to i+=2
