sullen dome
#

so it's definitely a reload-side issue

#

said already

#

one sec

lost matrix
#

I mean help, give, tp etc are also not blocked

sullen dome
#

^

vocal cloud
#

Wait you want to change the default one?

lost matrix
#

Just... use the preprocess event then. That even prevents /bukkit:reload

sullen dome
#

basically

sullen dome
#

what would be the message for /reload? does it include the /?

#

no they don't. next time i shall read first

#

even tho... now i have to remember not to reload with console :o

vocal cloud
lost matrix
sullen dome
#

i see. thanks blobDance

vocal cloud
sullen dome
#

to both of you :3

hehe

Why using Bukkit Command class?

#

Just use CommandExecutor

sullen dome
#

we had reasons

#

scroll up

#

just trying to figure stuff out rn

lost matrix
sullen dome
#

for example why the PlayerCommandPreprocessEvent doesnt work, while the ServerCommandEvent does?

vocal cloud
#

I'm doing something incredibly stupid rn but super fun if it works

sullen dome
#

development in a nutshell

#

okay

#

guys

#

WHY TF

#

does the PlayerCommandPreprocessEvent include the / but the ServerCommandEvent does not?!? god

#

that's fucking confusing

lost matrix
sullen dome
#

i do yes

#

even tho i know it's my panel which makes it work

lost matrix
#

Wh... how? That wouldnt work.

sullen dome
#

still... confusing

sterile token
#

Still confusing...

sullen marlin
#

gee its pink in here

sullen dome
#

because good people pay for spigat blobDance

sullen marlin
#

PlayerCommandPreprocessEvent is a subclass of the chat event, so that's probably why

sullen dome
#

kind of

#

i mean... you may make it more red in here? meowpwettyplease

sullen dome
#

yea, message says what you have to do

inner anvil
#

ik, i made it that way?

#

lol

sullen dome
#

oh my bad

#

didnt read the name lol

inner anvil
#

lol all g

celest isle
inner anvil
#

made it to where if the server isnt in the whitelisted ips for the plugin then it auto disables

sullen dome
#

idk if it's a "private" plugin, but... servers may change ip's

inner anvil
#

ik

#

thats why my contact info is there

#

:)

quaint mantle
#

Kinda easy to decompile then remove that line then use the pl again

sullen dome
#

true

inner anvil
#

true, though i plan obfuscation, and even then its buried

#

not just one line

#

no beginner would be able to just find and remove it

sullen dome
#

afaik, obfuscation isnt allowed with spigot

#

but dont take my word on it

sullen dome
#

ctrl+f entered the chat

quaint mantle
inner anvil
#

plus i could make it rely on that list with a webserver

#

and if the plugin wasnt on the webserver it dont funtion

#

nah

#

that can be removed too

#

all code

sullen dome
#

as a newbie

i'd open a decompiler of my choice, search for This plugin was not made for this server and bum, i most likely found it

inner anvil
#

if i used plain text

sullen dome
#

if you are sneaky and try to hide it with ```java
"this plugin " + "was not " + etc

i can easily search for single words
inner anvil
#

tru

#

what abt fonts? would that work?

sullen dome
#

wdym

inner anvil
#

ik there truly is no way to hide it completely, but there are roadblocks

inner anvil
sullen dome
#

well

#

as someone who wants to re-compile a decompiled plugin

#

i need to know how my ide of choice works

#

and if i know that

#

i can easily search through classes

#

assuming you don't use 100+ classes

inner anvil
#

external cmd handler

sullen dome
#

in case you do, i can still search for package names that seem to contain that shit

inner anvil
#

package names?

#

its in a random class

sullen dome
#

yea assumed that

#

so in that case... i'd go to the onEnable, and search all methods that are called, and methods that are called by called methods

#

and so on

#

until i find it

#

and finding the main-class takes me 10 seconds

inner anvil
#

main class is a smart way togo

next stratus
#

How can I have different textures on the same item?

sullen dome
#

so

#

no flex, but i'm an experienced dev
but i'm 99% sure that everyone who knows what methods do, would do exactly the same

#

hiding such stuff without obfuscation is bascially not possible

inner anvil
#

obv

next stratus
sullen dome
#

without making your code spaghetti-like for yourself

next stratus
#

Just don't share it without anyone 🥲

inner anvil
sullen dome
next stratus
#

If you don't share it with anyone they can't read your stuff

sage patio
sullen dome
#

i can hack your server blobDance

inner anvil
#

i also want to try anti cheat development

#

but i got no clue how to

#

lmao

sullen dome
#

obv i won't do that, because i have no idea how hacking works

#

and it's dumb shit

#

but i could

#

theoretically

next stratus
sage patio
#

but its possible with item name too

next stratus
#

Hm

sage patio
#

a block can have 2 texures with 2 names

#

like
barrier item, name : "Diamond1" = a texure
barrier item, name : "Diamond2" = another texure

inner anvil
# next stratus Hm

is your name a reference to or perhaps directly connected to DevBuckette?

sullen dome
#

wt

#

f

inner anvil
sullen dome
#

i would never even try to create a real anticheat

next stratus
next stratus
sullen dome
#

anticheats are always bypassable. so i'd never even try it

inner anvil
proud basin
inner anvil
#

and its def not

#

lol

next stratus
proud basin
#

I enjoy doing it

next stratus
#

"Please stop cheating, thanks!"

sullen dome
#

^

proud basin
#

I enjoy the part of trying to figure how I could detect a type

inner anvil
proud basin
#

Well what do you want to learn

inner anvil
#

Anti fly, kill aura, stuff like that

#

Auto clicker

#

Obv wanna start with the simple stuff

proud basin
#

Okay well first off don't use events for checking

#

packets are your friend

sullen dome
#

and there it starts... good luck

proud basin
#

lmao

#

Rivex join

sullen dome
#

god no please let me alone

#

i need to make my own server plugin rn

proud basin
#

What kind of kill aura check do you want to find?

#

There is different things you can look for when checking for kill aura

inner anvil
#

I have no idea, don't know anything about ac

sullen dome
#

btw always a good idea to tell how you make an anticheat in public chats

agile sinew
#

how to spawn particle at raytrace

proud basin
#

I recommend learning packets before you go into this

inner anvil
#

lol

inner anvil

neon minnow
#

why is this error coming upo

#

Type mismatch: inferred type is Boolean? but Boolean was expected

#

e.setCancelled(true) //Cancel the damages taken

golden turret
#

which packet is sent when a player starts pulling a bow?

#

PacketPlayInBlockDig isnt this one

If anyone has a fix for this or any suggestions I would really appreciate it, it's one of 3 last known bugs to my plugin.

sly trout
#

InventoryClickEvent how do you get the item that you had on your cursor and the item that you picked up with ur cursor?

delicate lynx
#

it's like getCurrentItem() or whatever

sly trout
#

ye i just want to know if those are after you clicked or not

#

if the getCursor is the cursor before you clicked or after

delicate lynx
#

after

#

I would assume

#

since when you click, the event fires, you are holding the item

#

maybe just output to the player to test it

agile sinew
#

Can I keep having events happen when I click left continuously?

golden turret
#

is there a packet sent when the player opens his inventory?

delicate lynx
#

I believe it's client sided

vocal cloud
#

@lost matrix @sullen dome I did it lmfao. Took a while to patch it but it works. 🤡. Unstable? Yes. Works? Also yes.

sullen dome
#

wait... you didn't just modified the server-jar, right?

vocal cloud
#

and no I didn't build a custom one this was done as bad as you think it was

sullen dome
#

this is boaring

#

:(

vocal cloud
sullen dome
#

i thought you did some really cool stuff

#

but you just replaced a line :/

lethal coral

I mean changing one line is better than doing nothing right? 🚎

First I modified the file and extracted it. Then I inserted it into the spigot jar

#

If md_5 is here I'm sorry your eyes have to witness this

sullen dome
#

you're a weirdo

vocal cloud
#

shrug1 I wanted to do it the worst way possible but hey it works. Reload command no longer works on my server

sullen dome
#

well, you did it tbh

#

so yea, not bad

#

noo, my mouse battery is empty

#

nahhhhhhh

All modern OS's can function with just tab

fuck you razer.. not with me

sullen dome
#

Does Bukkit#getWorld(name) get already created but unloaded worlds too, or only loaded worlds?

quaint mantle
#

Loaded worlds

#

iirc

sullen dome
#

aight

agile sinew
#

can i make animal attack player?

quaint mantle
#

Why can’t you?

#

Zombies can, so you can do it too

sullen dome
#

no idea tho "how long" it keeps attacking

I'm making a plugin where people can make kits, save them and use them. I think I'm going to use a database to store the kits and when they join load it the player's kits into memory, then if they create a kit add a new Kit instance to their map which is added to database once the player leaves. Is there a better way for me to do this?

sullen dome
#

correct me if i'm wrong

torn shuttle
#

hello fellow kids, I come once again asking how I can set the final damage of an entity damaged by entity event

sullen dome
torn shuttle
# 
       for (EntityDamageEvent.DamageModifier modifier : EntityDamageByEntityEvent.DamageModifier.values())
            if (event.getEntityDamageByEntityEvent().isApplicable(modifier))
                event.getEntityDamageByEntityEvent().setDamage(modifier, 0);

doesn't work

restive tangle
#

It's just a fun project I'm doing, I need a way to store the data permanently somewhere

sullen dome
torn shuttle
#

this is a bit of a maddening issue for how simple it sounds like it should be

restive tangle
#

/kit create (name), /kit (name), /kit save (name), /kit delete (name)

#

A yml?

sullen dome
#

EntityDamageEvent#setDamage(int)?

torn shuttle
#

that doesn't set the final damage

sullen dome
#

should be the final damage

torn shuttle
#

nope

sullen dome
#

what is it then?

torn shuttle
#

pre-modified damage

restive tangle
#

That'd work too

torn shuttle
#

actually I wonder if the sequence is messing me up

sullen dome
#

e.setDamage(EntityDamageEvent.DamageModifier.ABSORPTION, 1);
you could use this to set modifier-related damage

torn shuttle
#

that is what I did

sullen dome
#

which definitely isnt your case

restive tangle
#

I know that, Just don't really love yml files since using it as data storage like this is generally not liked by people

sullen dome
#

i personally always hated databases

#

and try to refrain from them

torn shuttle
#

the more you avoid them the more you will hate them because the worse you'll be at them

#

embrace them

#

they're pretty cool

sullen dome
#

yea

#

"cool"

restive tangle
#

I think I'll create new yml files when a player first joins and then store their data there

torn shuttle
#

fml alright I finally hit the right sequence

#

I need to do the thing I did then readd the damage by adding it with the BASE damage modifier

quasi flint
sullen dome
#

st.executeQuery("select * from a where b ="+ c);

torn shuttle
#

please just give us a final damage method...

sullen dome
#

couldn't tell why i think it's awful

#

no idea

restive tangle
#

Not a fan on of that idea, though I think that'd be faster

restive tangle
sullen dome
#

except it's your gpu

restive tangle
#

I like it

sullen dome
#

i like yml

#

let's keep liking what we like

restive tangle
#

It's the mongo database api

#

It has a legacy version too I think

sullen dome
#

i have no idea what mongo is

#

i dont want to tbh

torn shuttle
#

sql is fine

#

really after you make a handful of methods you probably don't have to do much else with sql directly

#

or use a lib I guess, I'm sure there's good ones out there for this

restive tangle
#

It is a databse, but unlike tables in mySQL it uses documents

sullen dome
#

i stay with my lovely yaml 💟

#

imagine people use toml Pepega

torn shuttle
#

I'm still using sqlite, I like the portability

#

will probably add mysql later but tbh I'll probably always prefer sqlite

sullen dome
#

or even worse, xml ahhhhhhhh

Can I ask here general java questions?

Completely unrelated to spigot

young knoll
#

I mean you can

#

But google probably has the answer

short raptor
#

Hey guys, I'm creating an inventory which has something like 20 itemstacks in it

#

Is there a more efficient way than having to write 20 times,
itemstack item = new itemstack
itemmeta meta = item.getitemmeta()
meta.setdisplayname()
etc, etc, etc

young knoll
#

Consider a util method to assemble the stacks

#

Or an ItemBuilder

surreal valve
quaint mantle
#

the command you registered in main class is heal

#

but in plugin.yml is 2 things

#

and ffs please make 2 different classes for 2 different commands and not in one class

surreal valve
#

I fixed that but it still comes

quaint mantle
#

i never registered 2 commands in one class so idk how it works

#

make 2 class for 2 commands

#

and setexecutor it

surreal valve
#

I already did that earlier but, the result is same

#

the error comes

short raptor
#

@surreal valve have you added your command to plugin.yml

surreal valve
#

Yes

#

I check the plugin.yml is in src also

short raptor
#

Strange

surreal valve
#

Yes, very strange

hollow bluff
#

API version has to be 1.16

#

not 1.16.5

surreal valve
#

wait, i'll try and tell you

#

Still comes

#

I'll try the whole code in eclispe

#

and tell you

hollow bluff
#

oh wait, why do you use a string inside of the setExecutor?

young knoll
#

They don’t

hollow bluff
#

Ah ye i see

surreal valve
hollow bluff
#

yeah I didnt see the commands thing above

surreal valve
#

Ok

hollow bluff
#

Have you tried making seperate classes for each command?

quaint mantle
#

without that you cant make commands !

quasi flint
#

He has an extra class ig 😂

quaint mantle
#

JavaPlugin implements command executor

quasi flint
#

The greetings class has to extend command executor

quaint mantle

surreal valve
surreal valve
surreal valve
quasi flint

It has to implement there

surreal valve
#

i have extra class

quaint mantle

ohh

#

Is it a bad idea to use a log4j logger from LogManager rather than the jul logger from JavaPlugin?

surreal valve
#

I seriously doubt what happened i think my intellij broke 😂

young knoll
#

JavaPlugin already implements command executor

hollow bluff
#

Remove label.equals and make bye and hello have two different classes and register them in ur main

#

Try that, works for me just fine

surreal valve
#

I have tried that

hollow bluff
#

Show

surreal valve
#

Wait

quasi flint
oblique blade
#

because log4j gives me format strings and jul does not

ivory sleet
#

jul delegates to log4j or whatever logging framework is used anyway

oblique blade
#

I figured as such, I wasn't sure if there was some magic bukkit does that bypassing it would break

ivory sleet
oblique blade
#

like plugin specific log targets or something idk

ivory sleet
#

Actually Idk, haven’t bothered looking into how deep the rabbit hole goes here

onyx fjord
#

damn, people used to be toxic on dev forums

surreal valve
#

Done

quasi flint
#

YOUR MAIN CLASS DOES NOT EXTEND COMMAND EXECUTOR

#

woops caps lock

#

sorry

#

shall nit extend

#

not

ivory sleet
#

I mean it does either way?

surreal valve
#

i have implemented it?

#

command excutor

quasi flint
#

only the classes where command logic is has to implement that

surreal valve
#

Then what do i do in main class

#

extend ot implement?

quasi flint
#

only extend javaplugin

surreal valve
#

ok

quasi flint
#

nothing more

surreal valve
#

ok cooli'll try and tell

hollow bluff
#

You dont need label.equals and when you register, do new Class()

quasi flint
#

i highly recommend this guide

surreal valve
#

I EXACTLY COPIED this

#

sor caps

#

but it wasn't kit

#

just a hello cmd

surreal valve
#

i mean

#

what do i have to do

hollow bluff
#

label.equals inside ur cmd class

#

remove it, you are already setting it when you register

#

Dont implement commandexecutor in main class

surreal valve
#

Remove this which i underlined?

or something else

#

It works now

#

thanks

#

no it works

onyx fjord
#

how do u stop command from sending the command name on execution

#

to chat

charred echo
#

return true

#

onCommand

sullen dome
#

or removing the usage from the plugin.yml

#

if onCommand returns false, it prints out the usage from the plugin.yml

charred echo
#

^ but the usage is useful no?

sullen dome
#

well

#

i always use custom syntax messages

charred echo
#

It's used in more places than just returning it from the CommandExecutor#onCommand

onyx fjord
# 
            if (sender instanceof Player) {
                try {
                    Player player = (Player) sender;
                    saveKit(player);
                    player.sendMessage("[HUBPVP] Kit saved.");
                    logger.info("kit saved");
                    return true;
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
        ```
so for some reason this returns false
sullen dome
#

i always do like ```java
if(args are right){
//do stuff
} else p.sendMessage("Syntax: /whatever <whatever>");

#

probably just my preference

#

does it catch an error? @onyx fjord

charred echo
onyx fjord
#

it doesnt send any errors no

#

yeah

sullen dome
#

well

onyx fjord
# 
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        if (cmd.getName().equalsIgnoreCase("hubpvp") && args[0].equals("savekit")) {
            if (sender instanceof Player) {
                try {
                    Player player = (Player) sender;
                    saveKit(player);
                    player.sendMessage("[HUBPVP] Kit saved.");
                    logger.info("kit saved");
                    return true;
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
        return false;
    }```
charred echo
#

return false;

#

then

onyx fjord
#

intellij told me to do it o.o

charred echo
#

it would throw the exception

sullen dome
#

weird

charred echo
#

are you sure it's not throwing an IOE

sullen dome
#

i mean

red sedge
sullen dome
#

try a sysout for the return value :o

red sedge
#

or did you just implement the method

onyx fjord
charred echo
#

what is it sending in chat

#

you sure you reloaded the server lmao

onyx fjord
#

/hubpvp

#

i restart when i modify the jar

sullen dome
#

yea the usage... from the yml

charred echo
#

if (cmd.getName().equalsIgnoreCase("hubpvp") && args[0].equals("savekit")

sullen dome
#

first of all, why would you check the commandname

charred echo
#

it needs to equal /hubpvp savekit

#

if only

#

/hubpvp

#

it return false

#

that's ur problem

onyx fjord
#

/hubpvp createkit sends hubpvp on chat

charred echo
#

yes

#

but

#

you are checking if

#

ubgfh

onyx fjord
#

lemme guess

#

args[1] ?

#

o.o

sullen dome
#

does it log the Kit saved?

onyx fjord
#

no at all

well

charred echo
#

you are doing that

sullen dome
#

if (cmd.getName().equalsIgnoreCase("hubpvp") && args[0].equals("savekit")) {
why

#

if your command is equal to /hubpvp, your arg[0] can't be savekit

#

cmd is basically the whole command

#

so these two checks can't both be true at the same time

charred echo
#

if the command is /hubpvp savekit it will return true, else if anything else it will return false. And in your case not even run the command logic at all

onyx fjord
#

oooh

#

so cmd.getName() is hubpvp savekit

#

when i do /hubpvp savekit

#

?

sullen dome
#

first of all, please refrain from checking the commandname

#

why do you do that at all

charred echo
#

^

onyx fjord
#

label

#

or what

charred echo
#

String label

#

is your hubpvp

#

then check args

onyx fjord
#

gotcha

#

now

#

how how do i stop error when i send /hubpvp

sullen dome
#

here's a small bit of help how it's supposed to look like

    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        if (sender instanceof Player) {
            Player p = (Player) sender;
            if (args.length == 1) {
                p.sendMessage(login.login(p.getUniqueId(), args[0]));
            } else p.sendMessage("§cWrong Syntax. Please use §7/login <password>");
        }
        return false;
    }```
#

just took my smallest command

onyx fjord
#

okay

#

thanks

sullen dome
#

there's never a need of checking command names.
in your onEnable you use getCommand("commandname").setExecutor(executor)
your Executor is ALWAYS using that "commandname" as cmd.getName()

charred echo
# 
@Override
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        switch(args[0]) {
          case "savekit" -> savekitlogic
          case "deletekit" -> etc... etc...
        }
        return true;
    }

not use an event

so my event checks for stuff

and i want for me to be able to do smth liek dis

red sedge
#

maybe check for packets

grim ice
#

public void onCustomAction(CustomActionEvent ev){}

red sedge
#

and call your own event

grim ice
#

i want my onCustomEvent to be called after the checks on the actual spigot event

red sedge
grim ice
#

is it that simple

red sedge
#

ye?

grim ice
#

oh ok then

#

is there a way to check for methods in a class

#

i want to make it so u can implement EventListener

#

(a class i make)

#

and add ur methods

#

which r ur events

vocal cloud
#

You want your event to fire after an event?

grim ice
#

yes

#

in a good way

vocal cloud
#

You can just set an event prio to monitor(?) and run your code there

grim ice
#

i have a ton of code

#

its gonna be extremely huge

#

so i just wanna make my own custom event

#

that i can listen to

#

isnt there a nice way to make it

vocal cloud
#

The only reason you really want a custom event is if other people are firing it

#

You can just create other classes to handle stuff as well

#

Onevent{subclass.dosomething}

hardy swan
#

I second that

ivory sleet
#

2Hex are you familiar with the observer design and strategy design pattern?

grim ice
#

not but i will learn that if i have to

hardy swan
#

You have to

ivory sleet
#

oh you already know those

#

Just that the names are to formalize the design

grim ice
#

oh

ivory sleet
#

Anyhow, doing something like that seems to be what you want to achieve tho tldr

grim ice
#

yes

#

im actually making a forge mod but its the same thing

#

same logic

vocal cloud
#

Forge the breakfast of champions

grim ice
#

anyways

#

conclure do u know how to make that

ivory sleet
#

Forge is special

grim ice
#

in a fancy way

#

how so

ivory sleet
#

iirc they use classloaders and other stuff to find the annotated event callbacks

grim ice
#

the use of the api is t he same

ivory sleet
#

Yeah almost

hardy swan
#

I personally think firing custom events by yourself using bukkit's plugin manager is fine (Maybe not for forge)

grim ice
#

u make an event u register it

#

same thing for spigot

ivory sleet
#

Tho for instance you can annotate a class with sth like @ModEventBus and then all methods will automatically be registered callbacks if they’re annotated

#

However in Bukkit you have to manually register

vocal cloud
#

I mean with a little reflection you can fix that

grim ice
#

i usually manually register

#

im on 1.8 forge

vocal cloud
#

Ouch

grim ice
#

that thing isnt there yet i think

#

however that crap is irrelevant to me rn

#

i need to know the logic

#

to make it

ivory sleet
#

Well Mike, you’d still have to tell somewhere what class holds the callbacks

#

In forge there’s just that annotation

#

I mean basically 2hex you have a collection of strategy objects (like consumer or runnable)

#

Then on given event you just run each one of them

grim ice
#

hm

#

im thinking about making all classes extending Listener (a class i make)

#

have their methods regarded as events

ivory sleet
#

Why use a marker super type?

#

hmm

#

I know JDA had a method onEvent(Event e) where you basically had to check instanceof

#

And that was just horrible

grim ice
#

i was about to do that LMAO

#

It seemed simple

ivory sleet
grim ice
#

there is gonna be like

#

7 events

#

that i would need

ivory sleet
grim ice
#

actually ill just use normal events

#

what im doing is checking when a message is sent in chat

#

then checking its content

#

and depending on the content i wanna do some code

#

i would prob name them smth like

#

DungeonFinishEvent

#

DungeonStartEvent

ivory sleet
#

Ah

#

Nice

#

Sure

#

Btw if you’re in forge

#

They do provide an event bus you could use

grim ice
#

yes thats how u register ur events

ivory sleet
#

Well you can use it for custom events also

grim ice
#

o

#

how is that possible

ivory sleet
#

Or well, might have to instantiate your own event bus instance

#

Idk

#

I mean

#

Their event bus is good Ig

grim ice
#

idk

vocal cloud
ivory sleet
#

Sure but that’s a rigorous solution

grim ice
#

ill jsut do

ivory sleet
#

At that point you’re better of with custom classloading (or maybe not, depends on what experience you got)

grim ice
#

Events events = new Events()
if(stuff) and other checks {
events.thatCertainMethod;
} else if (that certain thing and other checks) {
events.otherCertainMethod;
} else if (..etc

#

it would be a switch statement or smth

#

thats the stupidest

#

and simplest way i can do it

vocal cloud
grim ice
#

ill prob not do that

grim ice
ivory sleet
#

they’re not static sadly

vocal cloud
#

You use annotations to mark them same way spigot does it. I had an example somewhere but I think it used googles old reflection stuff

grim ice
#

so

#

what do u think is the best way to do it

ivory sleet
#

Yeah, but that requires manual registration

#

Not that manual registration is a big deal

ivory sleet
vocal cloud
ivory sleet
vocal cloud
grim ice
#

so is there a conclusion

#

is there a good method to do this
