maybe something to make myself :kekw:

young knoll
#

I think that is his equals()

tardy delta
#

thats what im doing kekw

spiral light
#

wow xD

tardy delta
#

shall i count that?

# 
public static boolean equals(Object... args) {
        Validate.isTrue(args.length % 2 == 0);
        for (int i = 0; i < args.length - 1;) {
            if (!args[i].equals(args[i++])) return false;
        }
        return true;
    }```
spiral light
#

static equals O.o i would rename it

grim ice
#

wont u need to override it

tardy delta
#

i dont know if it would work

quiet ice
#

myeh, it's fine

#

You can call it via ClassName.equals

tardy delta
#

im making like an utility method instead of doing stuff like this

spiral light
#

its fine but the name is already used

quiet ice
#

See Objects.equals

spiral light
#

what about "isSame" ?

#

or "isEqaul"

quiet ice
#

equals is perfectly fine

tardy delta
quiet ice
#

I wanted to say that it is perfectly legal to name your method like that

tardy delta
#

lemme try to run that code

tender shard
tardy delta
#

it works i guess

#

yea im doing weird things sometimes even though i like it

young knoll
#

It’s a nice little convenience method

#

Even if it is jank

tardy delta
#

it works 👀

hasty prawn
#

Why does it only accept an even number of args

spiral light
#

why is that red omg

#

my eyes

tardy delta
#

because its supposed to work with pairs

hasty prawn
#

Ah

tardy delta
#

equals(loc1, loc2, world1, world2) like that

#

😔

ye

tender shard
#

press shift twice

#

and then

#

oh wait

#

I thought it's here but it isnt

#

one sec

smoky oak
#

pressing shift twice doesnt do that

tender shard
#

check this

#

go to any bukkit file (decompiled)

#

then at the top "Download Sources"

#

or just

#

pres sshift twice

#

enter "Download Sources"

#

then choose "Sources AND documentation"

#

idk if it works for spigot, but it should work for spigot-api

smoky oak
#

thanks that did it

tardy delta
#

i see alot of utils

smoky oak
#

i needed to click on 'edit sources' tho to get that bar at the top

tardy delta
#

cant you ctrl click it?

How can i build my plugin without maven or gradle?

#

i can but the bllue bar with 'download sources' doesnt show up that way

I could walk you down the complicated path of manually compiling shit with javac but you don't want to do that.

#

And I don't want to do that either.

pseudo shore
#

i didnt want to mean that

spiral light
#

well you can easy modify the result of creating it with that template O.o

visual tide
#

or just like

spiral light
#

you just need to know what the pom is if your using maven template

visual tide
#

modify one line in your pom.xml or build.gradle 😐

Because the newest version does support 1.18

hi!

#

so

#

if i have that:

#

just use SlimefunItems.class

#

Okay why did you want to do that

lime wave
#

i am editing slimefun items to be in portuguese brazil

#

this is in english, but when i traduce i want to know what to do

tardy delta
strange patrol
#

You need to download the entire slimefun peoject, then edit the file and compile it again I guess

vocal cloud
#

Are they not open source?

strange patrol
#

They are

vocal cloud
#

Lmfao

lime wave
#

ye

vocal cloud
#

Just change the source then compile the whole project

tardy delta
#

870 lines smh

vocal cloud
#

You can't compile 1 class file

lime wave
#

ohh

tardy delta
#

look at what's inside 😳

With all those depends

tardy delta

it scares me

what do vanish plugins do when the allow you to access chests? like your velocity is like in spectator and your hands dont show but you cant go thru walls

tardy delta
#

they actually put you in spectator

spiral light
#

or invisibility effect ^^

tardy delta
#

thats why most of them dont allow you to edit the chest

#

then you would have the chest open effect but yea

spiral light
#

you can cancel the normal open of a chest ^^

#

or dont allow sending those packets

visual tide
#

youre kinda in spectator but you cant actually go thru walls

#

which is weird af

spiral light
#

example ?

tardy delta
#

i should take a look at the sourcecode

spiral light
#

if you "bug" when trying to go in walls its mostly spectator mode but in a special way

visual tide
#

you dont like lag back

#

its like youre in creative or survuval

#

the wall's just solid

spiral light
#

do you can see your hearts ?

visual tide
#

no

#

the ui is like in gmsp

#

but you cant go through walls

#

its super weird

#

try it

tardy delta
#

not all vanish plugins tho

#

i made my own so i cant speak xd

visual tide
#

supervanish does it

quiet ice
#

I know this is a really stupid question, but what method works like #giveExp but also takes mending in account

spiral light
#

spawn exp-entity on player location 🤡

quiet ice
#

I know that there is a dedicated method for this, but I cannot seem to find it

But perhaps I was looking at the paper javadocs, that would explain it...

obsidian tree
#

I created a Multi-module Maven project, and I'm using remapped-mojang. When I try to invoke a method which includes remapped-mojang things from different module, I am getting error like:
cannot access net.minecraft.advancements.AdvancementFrameType

incompatible types: net.minecraft.advancements.FrameType cannot be converted to net.minecraft.advancements.AdvancementFrameType

quiet ice
tardy delta
#

it returns if youre in spectator so i guess you're not in spectator

#

same with some other things

#

however for some things it seems that you enter spectator

spiral light
#

maybe just packet to send player in spectator

tardy delta
#

i dont get any wiser of it lets just take a nap

Hello i Play in a spigot server and Many farms doesnt work how i can fix it

mortal hare
#

is there any way in spigot to load world folder without using external plugins

#

i can tp to other world via execute command but im searching for a way to load it

#

i just don't want to use multiverse

quiet ice
#

The bukkit API should have a way to do that

mortal hare
#

yeah but i don't want to create hardcoded plugin just for this

proven river
#

Inside an Inventory holder class how do I access the player, for example if I wanted to get their playtime in a lore?

quiet ice
#

Though datapacks might be able to do it, but that'd be the same as vanilla

quaint mantle
proven river
#

Yea I do already but from that I wouldnt be able to set the lore or not?

quaint mantle
#

what do you mean by "set the lore"?

proven river
#

well exactly what it is, setting the lore

#

the description bellow and item

quaint mantle
#

of an item

#

ok

proven river
#

but with their playtime

#

So an event wouldnt rlly work for it

quaint mantle
#

Do you mean a player inventory

#

I don't get what you are trying to do exactly

#

Maybe im just dumb :D

proven river
#

Okay okay,

#

So

#

In an event you can do
e.getPlayer

and from that get all of the players things for example their playtime
but in an InventoryHolder class you cant do that

#

hope that clears it up

#

I want to access the player

quaint mantle
#

when do you want to access the player

#

If you look at the inventory holder interface, is just has 1 method: "Inventory getInventory();"

#

there is no way of getting the player no

#

Construct a gui based on player stats, and then open it

proven river
quaint mantle
#

you need to pass the information of the player who opened the inventory somewhere.

#

how does one open that inventory

#

through a command?

proven river
#

yes

quaint mantle
#

cool

proven river
#

Everything are in separate classes

#

GUI's
Command's
Event Handler's

quaint mantle
#

You will have to create the items from the inventory when the player runs the command, not before. when the command happens, you pass the player who ran the command to the init function.

#

then you can do whatever you want with it

proven river
#

hm okay I have no idea how to go about it but I'll figure smthn out

quaint mantle
proven river
#

oki

quaint mantle
#

what I have:

@Override public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
openYourInventory((Player)sender);
}```
#

of course you need to check if its a player and that stuff

Hello, quick question, a HashMap like this: Map<String, ItemStack[]> map = new HashMap<>(); can possibly cause a memory leak?

ivory sleet
#

nope

#

not inherently

rapid vigil
ivory sleet
#

Though, with that being said, I still recommend encapsulating ItemStack[] into its own class as it gives you more control over the code 😛

rapid vigil
ivory sleet
#

well

#

generally

#

if an object allows mutability

#

which means the state of the object can be changed

#

for instance:

class Obj {
  int i = 1;
}
#

can be considered mutable

#

since we can change the value of i

#

in this case, it is generally not safe to use Obj as a key for a map such as Map<Obj,ItemStack[]>

#

now in this case it is, as you get yourself an identity hashmap implementation

#

this is why we always use Vector::clone, or Location::clone when putting it as a key into a map (namely, Map<Vector,V> or Map<Location,V>)

rapid vigil
#

Damn thanks for the great explaination

ivory sleet
#

anyways the general idea is that, once an object has been put into a map as a key, the hashCode() of that object must NOT change

#

and since String is immutable, they are fine as keys

rapid vigil
#

Now I know why Player in a HashMap causes memory leaks sometimes

ivory sleet
#

yeah

#

Well, using UUID as the key is better in every possible way

rapid vigil
#

So saving UUIDs instead of Player in a HashMap cannot cause memory leaks?

ivory sleet
#

I mean generally speaking

sullen marlin
ivory sleet
# rapid vigil So saving UUIDs instead of Player in a HashMap cannot cause memory leaks?

memory leaks mean that you have some object which:

  1. Cannot be enqueued to garbage collection since it has some strong reference to it
  2. However you cannot manage this strong reference on demand (for instance if some array contains this object in the HashMap but there is no way of fetching it from your side)

Edit: the object is simply unreachable for garbage collection, and is unreachable for you, thus it just floats around in memory purposelessly.

Hello Olivo

(:

chrome beacon
#

Hi :)

rapid vigil
rapid vigil
#

Long time no see

ivory sleet
#

Well conversely, Java is incredibly slick when it comes to figuring out what objects can be enqueued for garbage collection. Anyhow, use a profiler maybe (to detect memory leaks)?

question: how are CommandExecutors handled internally?

e.g. if I've got

Hello I am having a problem with skript. I am making a rank paper which when right clicked on gives you a rank but the rank papers name is &7&lIron Rank Paper so when I put:
on rightclick holding a "&7&lIron Rank Paper" as a event it says error even without the " so I don't know how to make it work. Here is all the code :
on rightclick holding a "&7&lIron Rank Paper":
if player doesn't have the permission "iron.rank":
execute console command "/lp user %player% parent add iron"
remove 1 "&7&lIron Rank Paper" from the inventory of the player
if player has the permission "iron.rank":
send "&4You already claimed this rank" to player

Hi, I want to edit the major positive gossip when opening a villager trade menu using Protocollib but I can't seem to work out how to do it/which packet to listen for. I made this work a few version ago with nms but wanted to use protocollib as it seemed to promise cleaner/more understandable code.
Does somebody know how I can do this?

Whats the best way to check if a sign is on a block?
And get the block that the sign is on

#

Bumping, would like to know if it's possible to have a full automatic release from GitHub

woeful crescent
#

Yes

#

It's called github actions

hot warren
#

yep but I havent seen any spigotmc github acitons

woeful crescent
#

?

#

Wait wdym by upload a spigot plugin jar

#

like to the spigot website?

hot warren
#

yep

woeful crescent
#

alr

#

so you'd have to make a github workflow that used upload-artifact

hot warren
#

If it doesn't exist, that'd be a nice project to do

woeful crescent
#

then set your spigot download to the link to that workflow (https://nightly.link is a good tool for this as users won't have to login to github)

#

bc you can refer to an external site I'm pretty sure

#

does that work?

young knoll
#

Yes

#

But it wouldn’t post a proper resource update

woeful crescent
#

You're right

#

hmmmmm

hot warren
#

Wow, thanks! I'll configure my GitHub Actions to upload there, didn't know people had to be logged in to download release/build artifacts!

woeful crescent
#

Idk

hot warren
woeful crescent
#

Spigot API maybe?

#

i mean web api

hot warren
#

I bet you the Spigot API doesn't allow you to make a release

woeful crescent
#

there's a web api im pretty sure

hot warren
#

and I've scanned this discord and most of it is basic GETs

not anything that'd let you change the data

woeful crescent
#

rip

#

you COULD just link to the github

#

as the download link

#

link to the github releases page?

young knoll
#

Put full releases on spigot manually

#

And then link to dev builds in the description

#

On Jenkins or whatever

#

Yeah

granite burrow
granite burrow
granite burrow
buoyant viper
#

oh then yeah block face

topaz sinew
granite burrow
#

says that it doesnt exist

topaz sinew
#

use org.bukkit.material.Sign instead of the org.bukkit.block.Sign interface (the Sign class is deprecated tho), or change it to Directional and use getFacing().getOppositeFace()

#

So it would be

org.bukkit.material.Sign s = (org.bukkit.material.Sign) block.getState().getData();
Block attachedBlock = block.getRelative(s.getAttachedFace());
// or
Directional s = (Directional) block.getState().getData();
Block attachedBlock = block.getRelative(s.getFacing().getOppositeFace());
granite burrow
#

org.bukkit.material.Sign is deperciated

alright, im a still a bit confused so ima do more research and stuff

but this all kinda helps

In resume good obfuscation or decent one = pay/buy a good obfuscator like Allatori premium. Someone told me that he uses it to ofuscate premium resources and they never get deobfuscate up to know

Premium resources from mcm cuz spigot doesnt allow obfuscation 🤡

```ERROR: cannot verify hub.spigotmc.org's certificate, issued by /C=US/O=Cloudflare, Inc./CN=Cloudflare Inc RSA CA-2': Unable to locally verify the issuer's authority. ERROR: certificate common name spigotmc.org' doesn't match requested host name hub.spigotmc.org'. To connect to hub.spigotmc.org insecurely, use --no-check-certificate'.

Will I be fine to just insecurely connect?

Is HikariCP supposed to take up about 250KB worth of space when compiled into a jar?

I’m using maven to import it and it just seems like a bit much. My jar goes from 432KB to 658KB.

quasi flint
#

Why that jar so massive

#

432 still huge boy

kind hatch
#

Oh shit sorry I meant KB not MB

quasi flint
kind hatch

Yea… but I want to keep it as low as possible. The limit for plugins is 4MB and even though I’m not even close to it right now (about 11%) I’d rather keep it low in the first place.

# quaint mantle Cant you post an external link to the plugin download?

Maybe, I’d have to find somewhere to host versions. It might also break how my plugin updater works. It also adds that extra step of having to leave the site in the first place, which some users don’t like.

I’m not close the the 4MB limit, its just that I could easily reach 1.5MB quickly with what I want to add.

Also, all I’m using with Hikari is the DataSource class which I would hope isn’t 250KB.

it's not possible to detect a right click on air without jumping through some weird hoops right?

zinc spire
#

How can i ride the ender dragon in overworld?

sullen marlin
#

the client literally does not tell the server about right click air unless youre holding an item

#

if youre holding an item the normal event is fired

#

spawn an ender dragon, add upirself as passenger

zinc spire
#

It didn't move

smoky oak
#

can you somehow get extra key presses? Or do all triggers have to be vanilla (for example right clicking with a stick as trigger?)

sullen marlin
#

you cannot get right click air without an item

smoky oak
#

hm

zinc spire
smoky oak
#

is there a list of what client actions get sent to the server? If i can use something like Hightlight Players (Spectrator Mode) as trigger, that would probably solve that problem too, but I'm not sure what the client actually does when that key's pressed

sullen marlin
#

Idk what that is but it sounds client side

smoky oak
#

thats why i asked if there's a list

#

also do you per chance know if the 'swap items with offhand' gets sent to the server if both main and off hand are empty?

sullen marlin
#

No, but there is a list of events in the javadoc

#

And try it and see, but doubtful

spiral light

is there an BlockDamageAbortEvent md5 ?

you can't use that for remapped-mojang the last i tried

Hi! How would I make a plugin that allows a player summon zombies that attack other players but not the summoner?

I don't think implementing collection types yourself is gonna help you learn the language.

#

If anything, it'll just make you more frustrated and give up trying to learn the language.

#

And even then, Java is tethered to the stdlib in a lot of ways.

#

You cannot use primitives in generics without the standard library (Integer, Float)

#

You can't even pass a value of any type without the standard library (Object)

So it isnt wrong to have this method on Interface:

T - Cuz for mongo I need to return Document and Mysql a ResultSet

K... - Cuz Mongo and Mysql requires different Arguments

Why?

hardy swan
#

What usefulness does K provide

sterile token
#

I need Arguments so i them do a conclusiok

lavish hemlock
#

Yeah you'd be better off with Object

ivory sleet
#

Verano usually you probably want to provide an even higher abstraction

lavish hemlock
#

There's no need to use generics if you only use them in one place

young knoll
#

I don't even expose queries atm

ivory sleet
#

Assuming you’re trying to create a polymorphic design of some sort

sterile token
lavish hemlock
#

e.g. This is pointless:

public <T> void uwu(T o) {
    if (o instanceof String s) {
        // ...
    }
}
#

Sorry wait no

ivory sleet
#

uwu

vocal cloud
#

Polymorphism uwu

lavish hemlock
#

Because you never re-use T

#

And it could just be replaced with Object

hardy swan
#

As far as polymorphism is concern, if you have a common interface such that you can declare K to be <K extends SomeSuperType> then K will be useful

#

But i assume you dont

dusk flicker

Pog abstraction

ivory sleet
#

I don’t believe we have super in generics

hardy swan
#

So Object it is

ivory sleet
#

except if it’s a wildcard
