[quaint mantle]

?kick!!!

[mortal hare]

In my country we have January 13th, February 16th and March 11th as our national days

[river oracle]

Yo can we get a pr to fix that

Imajin

Do it

[quaint mantle]

Fuck that

[eternal night]

Did Imajin contribute anything yet ?

have never seen them on the spigot stash

[quaint mantle]

not to spigot

[mortal hare]

send a packet

[eternal night]

ah

[mortal hare]

packette

[river oracle]

Packette

[quaint mantle]

packete

[eternal night]

Yea, packet might be the only real solution here outside of repeatably setting it

[mortal hare]

https://tenor.com/view/baguette-baguette-cat-nom-nom-french-cat-frenchy-gif-20649123

[eternal night]

|| or switching to paper and using better API ||

[mortal hare]

garlic bread is the best

[eternal night]

a universally true statement

[river oracle]

What do you have to do to beable to contribute to spigot

[eternal night]

sign the CLA

[river oracle]

CLA?

[pliant oyster]

WorldGuardPlugin#getRegionManager no longer exists, what should I use now?

[eternal night]

?contributing

aww

?contribute

[undone axle]

You can find information about contributing to Spigot at the following links:
https://www.spigotmc.org/wiki/cla/
https://www.spigotmc.org/wiki/guide-contributing-to-spigot/

[eternal night]

eyy

[river oracle]

Is it a gov document cuz then I can't not 18 moment

[eternal night]

no

[mortal hare]

EnumMap vs switch case

guys

what's better

[eternal night]

but you have to provide your full legal name and address and shit

[mortal hare]

https://tenor.com/view/decisions-homer-simpson-homer-the-simpsons-simpsons-gif-5987891

[river oracle]

Uhm is that public?

[eternal night]

no

if you'd have to dox yourself to contribute, spigot would have less than the 2 contributors rn

[maiden thicket]

💀

[river oracle]

Why would I give my address hell nah ill just fork it and make changes I want lol

[eternal night]

I presume switch case ? By like 3-4 instructions

fork it != contributing to it

[river oracle]

Yea ik but 🤷‍♂️

[eternal night]

and like, have fun forking spigot

[pliant oyster]

yo\

[eternal night]

it is pain

[mortal hare]

forking paper isnt 😉

[eternal night]

it isn't 🙂

[river oracle]

Ə

[river oracle]

Do you gave to copy paste everything lol

[eternal night]

no

but like

spigot toolchain is just painful

[river oracle]

Figures

[mortal hare]

Finally IE is DEAD

imagine how much relief web devs have after this

[river oracle]

I'm curious why you gotta send that info to contribute

[brave sparrow]

Because it’s a legally binding contract giving spigot the right to your contribution

[eternal night]

Well you are signing a contract

yea

[mortal hare]

they can finally remove those activeX shitty polyfills

[river oracle]

I can't sign contracts lol

[brave sparrow]

Then you can’t contribute

[river oracle]

F

[eternal night]

how young are you o.O

if you can use discord you can sign that contract

[brave sparrow]

It’s to protect spigot from some idiot like Wolverness contributing and then DMCA the codebase years later

Like he did to bukkit

[river oracle]

I thought you had to be 18 to sign any contracts

[pliant oyster]

WorldGuardPlugin#getRegionManager no longer exists, what should I use now?

[river oracle]

Atleast in America

[brave sparrow]

You need parental consent under 18

[river oracle]

Ye fuck nah

[eternal night]

Do you ? dunno about the US, but like

you should not have to

[brave sparrow]

You definitely should

[eternal night]

but ehhh, this is not legal advise and I am not a lawyer 🙂

[brave sparrow]

As a minor you legally can’t enter into any kind of contractual agreement

It’s not enforceable

That’s why parents have to co-sign

Kids aren’t expected to know better

[pliant oyster]

fuck sake can someone answer my question

[brave sparrow]

I’m sure worldguard has a discord for their API

Ask there

[eternal night]

https://worldguard.enginehub.org/en/latest/developer/regions/managers/

as well

[twilit nimbus]

I'm trying to add tab completion to my command which supports multi-word arguments in quotes, and everything's working except if you manually type the first word along with the space, the visual moves to the next word, and if you then press tab it inserts the whole string. Is there a way to stop that? A specific example of the command I'm trying to get to work is /war start "Team One".

[kind hatch]

You can't have spaces in your arguments because a space denotes the next argument. Even if it's in quotes. You'd end up with args[0] = "Team and args[1] = One"

[glass sage]

Hello does anyone know how i could send a pure packet without going through the netty thread? and therefore send it whenever I want without being dependent on the 20 tick limit

[dusk flicker]

I mean, you CAN. Its just more work

[kind hatch]

Yea, but you wouldn't get good tab completions from it.

Not without a lot of potential jank.

[twilit nimbus]

I have it all working except when I actually press tab in the second word it inserts the whole string instead of just the missing part.

[buoyant viper]

interact probably fires for right click, i just want left

[glossy venture]

i think for left too

but idk

oh no nvm

maybe not

[paper viper]

Actually, arguments such as greedy arguments can contain spaces

And also you can use quotations for arguments to define a String

If you use brigadier, a greedy string will take anything after

[quaint mantle]

pulsebeat

fix my buildtools problem

[pliant oyster]

How would I change a players name tag, not using scoreboard or setDisplayName

Basically lets say you want a prefix for the player, only the nametag above his head, not in tab or chat or anything

Custom name wont work btw, "This value has no effect on players, they will always use their real name."

[mortal hare]

armorstands

[crude loom]

Correct me if I'm wrong, but I think you will need to use packets
I used packets to alter what armor do players see (to hide weared armor)

[pliant oyster]

any example?

[crude loom]

I'm actually new to packets
But here you can find all the packets and their descriptions: https://wiki.vg/Protocol

[pliant oyster]

I cant use CraftPlayer for some reason

[lost wolf]

How can I access and modify an Entity's data similarly to the /data command?

[pliant oyster]

attributes?

idk what u mean

[lost wolf]

I'm trying to access a ZombieVillager's level, in a Villager you can access this value with the method getVillagerLevel(), but ZombieVillagers lack that specific method

In game you can use the command /data get entity <entityid> VillagerData.level to read this value

I haven't tried that, I'm currently unfamiliar with that concept

Is this the only way to access this information?

[river oracle]

Ye

Reflection I'd op

[lost wolf]

But the villager level doesn't seem to be accessible through a ZombieVillager object 🤔

[crude loom]

is it possible to check a player's title?

[lost wolf]

Which public method?

[crude loom]

I mean the title displayed by player.sendTitle

thinking about it there is a simpler solution for what I tried to do

but thanks for the help!

[golden turret]

can i pass a null ItemStack in the array of PlayerInventory#setArmorContents?

[glass mauve]

yea

its @Nullable ItemStack[] items

[twilit elbow]

Hi, where can I contact support on spigotmc page / open a ticket?

[tender robin]

why does this not work?

@EventHandler
    public void onJoin(PlayerJoinEvent e) {
        Player p = (Player) e.getPlayer();

        Bukkit.getScheduler().runTaskLater(plugin, new Runnable() {
            @Override
            public void run() {
                if(p.hasPermission("fthme.join.gm")) {
                    p.setGameMode(GameMode.CREATIVE);
                    p.sendMessage(SP + "§5KREATIV");
                }else{
                    p.setGameMode(GameMode.ADVENTURE);
                }
            }
        }, 20L);

    }

"Does not working" is a useless statement. Please describe what exactly is not working, what you expect it to do, and what actually happens. If you get any console errors, also ?paste the entire stacktrace.

so your plugin variable is null

[tender robin]

y

[buoyant viper]

fuk if we know

[tender robin]

    public static Plugin plugin;

    public joingm() {
        this.plugin = plugin;
    }

[quaint mantle]

ew

[tender robin]

lmao

what else can I do so it works?

[crude loom]

where do you initialize this class?

[buoyant viper]

this.plugin = plugin

what

• 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.

[quaint mantle]

this.nullVariableFromStaticContext = null;

[crude loom]

oh i didnt notice you dont pass a variable there

[trim creek]

Aight what kind of problem a plugin can get, that a unused code (basically just two slashes) are detected as errors?
(ex.: line 40 is //, and nothing more, but yet is still an error)

[quaint mantle]

Its not an error

show a screenshot of your code

[crude loom]

try to recompile your code

[trim creek]

Well, the console prints for line 40 which is just two slashes, so now what?

[dawn plover]

what event do i need to check for if someone is standing on a block

or is it even a event

[buoyant viper]

isOnGround? idk

or get the block below them

and if its solid then yeah its a block

[trim creek]

(I am actually trying to import the player data into MySQL, but it just messes with me)

[tender robin]

try BlockEvent

[buoyant viper]

?jd-s for me self

[undone axle]

https://hub.spigotmc.org/javadocs/spigot

[buoyant viper]

oh pog theres an Tameable interface

[dawn plover]

thats an abstract, you cant check for that

or at least not that i know of

but i will try to find the block below player, i think thats a good idea

[tender robin]

so guys what can I do with my code?

[crude loom]

your constructor needs to receive a variable
without that you are setting a variable to itself (null to null)

[buoyant viper]

dont need the constructor since the field is static

but itd be better to use di probably

so add the parameter to constructor and then make the field non static

?di

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

[loud junco]

    private Plugin plugin;

    public joingm(Plugin plugin) {
        this.plugin = plugin;
    }

Initialize the class in your main class i guess and pass the plugin there - dunno, this looks like you're passing the bukkit's Plugin class which you should not unless your main class is called Plugin. Change it to your main class (that should extend JavaPlugin).

as of now, you were passing the variable to itself

[river oracle]

Player move event

[dawn plover]

i saw that, but isnt that when a player is moving only

so when a block get changed while a playing is standing still

it wont react

[river oracle]

When you change a block maybe you can check I'd there are entities above it and apply logic there

[dawn plover]

oh, right

thats actually good idea

[trim creek]

Nevermind got the fix. I just had to export the plugin with another jar name.

[tender robin]

I made a new Plugin with the same code now it works without doing this

[loud junco]

without doing what?

i expect you did everything static, which is a way but a ugly way

[tender robin]

I just wrote this again in the main class

[tender robin]

it is

[loud junco]

yeah, i would split your events into a Listener class

[tender robin]

but I just wanted to know if I did it right or not

[loud junco]

and register them - getServer().getPluginManager().registerEvents(new YourListenerClass(), pluginInstance);

[fallen steeple]

Packet armorstand not working anymore ?

because i dont have suggestion like "setCustomDisplayName" or something like that

[ebon topaz]

if (event.getEntityType().toString().equals("ENDERMAN")) {}
```how would I make this like a if not return

[fallen steeple]

else ?

[modest garnet]

if your in intellij type .not after ("ENDERMAN")

??

[fallen steeple]

if(){
// Code
} else {
// Code
}

[ebon topaz]

What about return?

[modest garnet]

wdym return?

[ebon topaz]

Like cancel if it’s not enderman

[fallen steeple]

its a event ?

[modest garnet]

return <what u want to return>; <--- if not void

if void just put return

[slim brook]

Hello guys

Do you know an API or anything for use custom_model_data or similar in 1.8 ?

I'm searching since 2 days but i didn't found anythings work

It's for add an texture to a custom item

[spare heron]

custom model data doesn't exist in 1.8

And i dont think they are alternative

[slim brook]

Yeah I know that why i'm asking if someone have alternative

[slim brook]

That exist

I saw that in youtube video

[spare heron]

https://tenor.com/view/pings-off-reply-pings-off-reply-ping-discord-reply-ping-gif-22087396

[modest garnet]

or just deal with a ping and stop crying

[slim brook]

https://tenor.com/view/what-are-you-talking-about-huh-what-what-are-you-saying-stirring-gif-17820207

Lewi you have an idea ?

[river oracle]

What

[slim brook]

Maybe cause i ping back him but he did first X)

[river oracle]

I always ping on reply

[slim brook]

Yeah that logic

But not for all that i see

[modest garnet]

nah sorry

[slim brook]

F**k

If someone have an idea or alternative if you can send me a mp :3

[river oracle]

Iirc this isn't even possible in 1.8 may be wrong If it is you'll have to dig around nms

[slim brook]

Yeah maybe

[lost matrix]

Its not possible in 1.8
Not even with nms. The game simply had no such features back then.
1.9 introduced custom textures based on the damage of an ItemStack.

Thats what you have to live with if you decide to use outdated, ancient, broken software.

[buoyant viper]

pov the person ur talking to doesn't know how to silence notifications

[river oracle]

Wow too far man stop being honest

[slim brook]

Cause Ex Pvp mechanic ^^

[fallen steeple]

why nms methods are hidden

[river oracle]

They aren't

Depending on what you want to call

[fallen steeple]

For armor stand

[lost matrix]

Stop complaining about the adhd pvp and invent a new exciting custom pvp mechanic.

[lost matrix]

Did you add nms to your classpath?

[fallen steeple]

I want to do NMS armostand to make armorstand display the name of player in 1.16 it work but in 1.19 i cant see the methods

[fallen steeple]

yes

i used buildtools and replace spigot api with spigot in maven

[lost matrix]

In 1.19 the method names are completely different. They use the official mojang names now.

[fallen steeple]

oh okay

[lost matrix]

Thats not how you do nms in 1.19
Since 1.17 the process of how to get nms to work has changed

[fallen steeple]

ah yeah I'm damn late

there is a tutorial to learn how to use nms in 1.19 ? because i searched about 2 hours and i cant found nothing

[lost matrix]

https://www.spigotmc.org/threads/spigot-bungeecord-1-19.559742/
Scroll down to "NMS"

[fallen steeple]

Thx!

oh yeah i didnt see 1.17 is clickable

[fossil eagle]

[vocal cloud]

99% of people use intellij so

[modest garnet]

maybe dont use vscode lol

[viral pike]

Hello, i have question
I just want to change a value and it doesn’t change anything

main.getConfig().set("whitelist.work",false);
main.saveConfig();```
Config.yml
```yml
whitelist:
  work: true 

Thank you in advance 😄

[fossil eagle]

I prefer VSCode to Eclipse.

[river oracle]

Vscode is nice lol I like it but I don't use the bloatware called windoes

[fossil eagle]

How do you build your Maven projects?

[river oracle]

Use the buttons they provide

Otherwise for command line I'll use mvn clean install

[fossil eagle]

What button are you pressing? I've tried the "package" and "install" ones and they don't work.

[river oracle]

You also have a command not found compiler errorr lolI

[fossil eagle]

Yeah it's running this command when I try "install" the project.

[river oracle]

Try just mvn clean install in the proper directory including the pom

[fossil eagle]

Not sure how to get it so that I can use maven from the command line tbh

[timber lodge]

Plugin antiRedstoneClock

[modest garnet]

how to remove the "no API version" method in the console
as i want my plugin to work on any version.
is this the wrong way to do it and if so how do u do it

[fossil eagle]

So after you mvn clean install, is that making the jar file that can be put in the plugins folder?

[river oracle]

Yea

[fossil eagle]

Finally got everything working on VSCode only took me 5 hours lmao

Thanks for the help

[river oracle]

Np nerd

Get good next time

[river oracle]

Null points error

[fallow crescent]

and that means?

How do i fix

[river oracle]

Idk 🤷‍♂️ theree a null point error I have 0 other information from you other than that I'll help yoh here and send a few useful links

[fallow crescent]

wait

that's the line

https://stackoverflow.com/questions/3988788/what-is-a-stack-trace-and-how-can-i-use-it-to-debug-my-application-errors

?npe

[undone axle]

The NullPointerException, (commonly referred to as NPE), is thrown in the following cases, but not sealed to: 1. null is passed into a method or constructor which does not allow it; 2. When trying to access a field on an object pointing to null; 3. Casting null to a primitive. See https://stackoverflow.com/a/3988794/17047120 for information on how to debug NPEs.

[fallow crescent]

I want to fix the error, not to know what the error is.

[river oracle]

Don't you have to know what it I'd to fix it

If I spoon feed you here you'll come back if you learn you'll beable to do it yourself in the future

[river oracle]

Now what command did you send to your server

[fallow crescent]

/awc

[river oracle]

Ok now when you do args[0] that's an array of arguments you send.

You can't check for something that could exist without checking if it exists first

[fallow crescent]

yes i know that, but I don't know how to change that.

[river oracle]

For example your assuming every time someone runs aws they will have an argument such as enable or disable attached

[fallow crescent]

I'm very new in java

[river oracle]

So your assuming they will add an argument like so

/aws enable
/aws disable

So if someone were to run
/aws
and you check if an argument exists null a synonym of nil or nothing will return because there Is no argument

[fallow crescent]

Ok and how do I add the argument for aws?

[river oracle]

Now how do you combat null pointer errors or npe so it's fairly simple

Pretty simple

You can do something like

If object == null or in the case of an array of arguments you check for length so if length == 1 the following things can happen

Command arguments are structured like most list indexes in programming for example you can think of it like do
/aws arg0 arg1 arg2 arg3 arg4
And so in

If you were to run
/aws it's obvious that arg0 doesn't exist so therefore when you go looking for it it won't return anything and be out of index

Indexes always start at 0

[fallow crescent]

okay hmm

then enable args1

and disable args2

or what

[river oracle]

No so you want your commands to look like this right?

/aws enable
/aws disable

[fallow crescent]

yes

and /aws for an info about the plugin

[river oracle]

So enable and disable in the examples above are at the index 0

So when you do args[0] it'll get enable and disable

[fallow crescent]

ok

[river oracle]

But with the current way your code is structured it's automatically assuming your command will always have 1 argument

So you need to check if that array (think of it as a list) is 1 item long

Before you can check if the argument is enable or disable

[fossil eagle]

A null pointer error is when you try and dereference something that doesn't exist.

[fallow crescent]

damn

[fossil eagle]

So you have a pointer that's not working properly.

[fallow crescent]

and what do i must change that /aws works?

not only /aws enable / disable

[river oracle]

You need to check array length to see if it contains 1 argument before checking if its enabled or disable

so the sudo code would be
If array is length of atleast one continue to logic

or alternatively

If array isn't length of 1 return true

[fallow crescent]

ok

use the lowest version api u need to support

[lime moat]

I'm almost certain the components aren't new that I'm using since it's very basic stuff :P

Where can I change my api version, sorry?

[buoyant viper]

change ur paper version in there to be 1.16 instead of 1.19 too

and then in plugin.yml make api-version: 1.16

[lime moat]

<version>1.16-R0.1-SNAPSHOT</version> like this?

how do you edit the code in a plugin?

Open compiled class in the jar files

And edit them with your unmatched knowledge of the compiled language

[still light]

got it thanks all

[hardy swan]

If you meant to debug your plugin and find it troublesome to restart every time you make a change, there are some debugging tools out there able to connect to the server

But every time I use it my server will just crash after some time being stuck on the same tick lolol

[ivory sleet]

You can use hotswapping with for instance dcevm, plugins like PlugWoman can also be nice to use for quick reloads though should definitely not be used on production.

[rough basin]

how to change attack speed of item without NMS?

[lost matrix]

Just set the attack speed attribute of the item,

[rough basin]

is it affects all of item?

i can't code now so i cant test

[lost matrix]

No. If you want to increase the attack speed of all items then you should just increase the base attack speed of the player.

[rough basin]

I was asking if items like 'apple' could modify the attack speed, not only tools.

Bruh said it too hard.
Can I make the dragon with a speed of 2?

[quaint mantle]

Cus pom was selected as module?

[lime moat]

I have 0 other options https://fwoostyhub.com/🎤🌖🏠🚐

[quaint mantle]

You should just use build in maven. "Mvn clean install"

[sleek dragon]

can I append a ComponentBuilder to another ComponentBuilder?

How could I run a function that returns several Components that I want to append to a ComponentBuilder?

[lime moat]

Where would I find that? I see an install or compile

[vocal cloud]

You can append components to each other no?

[sleek dragon]

You can make a new ComponentBuilder and append stuff to it like TranslatableComponents or TextComponents but I have a function that creates a long list of Translatable/Text components appended together and i want to append those to the main ComponentBuilder in a different function

[quaint mantle]

I think you can use the search bar and just enter maven clean install, the option will show then.

[vocal cloud]

Then pass the builder into those functions?

[sleek dragon]

idk why i didnt think of that

thanks

[lime moat]

There's a search bar? https://fwoostyhub.com/🍜🍵🪐🤎

That’s the maven life cycle interface if I am not mistaken

[lime moat]

https://fwoostyhub.com/👄🍧👀💗

[ivory sleet]

Same

You usually use BukkitAudiences.create(plugin)

And well… first check if the class is loaded during runtime if you’re not providing a classload of it yourself

[lost matrix]

Download the minecraft dev plugin for intellij and let it generate a clean project for you.

[humble tulip]

in your pom

maven compiler source and target to 16

[lime moat]

[quiet ice]

Add the maven-compiler-plugin and set source and target OR relese

[lime moat]

[quiet ice]

Alternatively use the properties to set target+source

[lime moat]

    <properties>
        <maven.compiler.source>16</maven.compiler.source>
        <maven.compiler.target>16</maven.compiler.target>

May be an Adventure error, but not 100% sure

[ivory sleet]

Adventure wasnt a part of paper in 1.16.5

You might have to shade and relocate

[lost matrix]

You cant just build a maven project like that.

[ashen quest]

this looks so cool ngl

the embed and the picture

[lost matrix]

Why do you have "outputDirectory" configured? Do you even have this path on your pc? D:\AntiWeather\Plugins

[lime moat]

[lime moat]

It appears to have a build success now, what...

[lost matrix]

[lime moat]

Yes

Thank you for the maven help, I don't understand why that directory was doing that...

Now, to the console error: https://docs.adventure.kyori.net/platform/bukkit.html isn't this adventure?

[lost matrix]

yes. After compiling with maven the error should be gone.

[ivory sleet]

Not entirely

[lime moat]

I do also have this one: https://docs.adventure.kyori.net/minimessage/api

[ivory sleet]

That’s just the Bukkit platform

[lime moat]

    <groupId>net.kyori</groupId>
    <artifactId>adventure-text-minimessage</artifactId>
    <version>4.11.0</version>
 </dependency>```

[ivory sleet]

You probably want to add just adventure as well

the base dependency

[lime moat]

Where would I do so?

(Also, would it work on 1.16.5-1.19)?

[ivory sleet]

It would but it’s a little bit special

You see…

In 1.16.5 adventure isn’t a part of paper

But in newer versions adventure is a part of paper (the classes get shipped with the paper jar)

[lime moat]

Yeah, that's also another thing, I need it to work with default spigot :P

[ivory sleet]

Why depend on adventure at all then?

[lime moat]

sender.sendMessage(MiniMessage.miniMessage().deserialize(prefix_message + ' ' + no_permission_message, Placeholder.component("permission", Component.text("rtm.fly"))));``` This is the only way that I'm aware of to replace something in my config file with something else

(replace <permission> with rtm.fly)

[ivory sleet]

Oh you use mini message

[lime moat]

Yes

[ivory sleet]

I mean why not just MiniMessage.miniMessage().deserialize(message.replace("<permission>","rtm.fly")) and then take the component and just convert it to text and send it

Suboptimal but that’s that

[lime moat]

So, something like java sender.sendMessage(MiniMessage.miniMessage().deserialize(message.replace("<permission>","rtm.fly"))); would send it?

[ivory sleet]

Not with spigot

Since deserialize yields an adventure component

[young vine]

Don't suggest text replacements when a full placeholder system exists

What's wrong with placeholders?

[ivory sleet]

Oh yeah don’t mind me on that one… but anyway you (froosty) probably have to shade both mini message and adventure to make that work on spigot 1.16.5

[lime moat]

How shall I shade? (I'm very new to Java if you couldn't tell heh)

[young vine]

To use MiniMessage on legacy systems you need to shade MiniMessage, adventure and adventure platform so that you can actually send components

But why support legacy when the majority moved on? :/

[ivory sleet]

            for(int x= 2000; x> 0; x--){
                 //setting stuff
            }
}```

Server will crash 100%
You need to distribute this over several ticks.

[glossy venture]

you can do it async

if you get the nms chunk

its block palette is synchronized

and yeah distribute it over multiple ticks

[hybrid spoke]

its not

[glossy venture]

yeah it is

im pretty sure

[hybrid spoke]

but you can manually clock the semaphore behind it

its not, not in spigot

[kindred valley]

Is there any tutorial? I dont know what is nms

[hybrid spoke]

paper made it synchronized

[glossy venture]

oh

bruh

[hybrid spoke]

spigot will throw exceptions at you

[glossy venture]

sucks

[chrome beacon]

Bad idea

[glossy venture]

cant you synchronize it yourself

[kindred valley]

Can this fill between 2000x2000?

[glossy venture]

the data is volatile tho

[hybrid spoke]

you could, but have to inject your own threaddetector

[glossy venture]

BRUH does spigot have that async thread detector built into nms

thought only bukkit api

[chrome beacon]

There is a reason why that exists

You shouldn't modify the world on another thread

[glossy venture]

if its synchronized

you could

and the data itself is volatile

so it wouldnt cause any concurrency errors

[hybrid spoke]

but at some point that would block the main thread

[glossy venture]

you can do it per chunk sections

and if you subdivide the process into different threads, you can speed it up even more

if you make sure they all do different parts

and never conflict

[ivory sleet]

Sure you can just put everything behind reentrant-able locks, but that will make your application suboptimal in terms of performance, if you wanna do things faster you’d have to java 9+ memory ordering effects along with compare and swap stuff, but that is hard to test and not at all trivial, as you probably know just setting everything to volatile isn’t very optimized either as you’d essentially be forcing local registries to flush too frequently if every non final variable would be put under memory effects of volatile (and as I hope you’re aware… volatile doesn’t solve all problems with concurrency inherently, especially when you need to invoke a set of operations in one go, where proper atomicity is needed)

[humble tulip]

words ^

[glossy venture]

dont think it would take too big of a performance hit, at least better than blocking the whole main thread with the operation

[ivory sleet]

I mean you can just distribute the operation over several ticks

As I believe smile even wrote a guide for that

[humble tulip]

people need to learn how to use repeating tasks as do{} while() loops

so many people sturggle to understand that

[ivory sleet]

Yup

i think i have something that can paste blocks tho

i'll paste it in a sec

[dense crow]

heyho, i have a question. i wanna make a door permission lock, what means that only permissions what i set to them can open the doors.. how do i do that? im trying since 2 months and found no working soloution

[humble tulip]

        Iterator<Block> iterator = cuboid.iterator();

        Bukkit.getServer().getScheduler().scheduleSyncRepeatingTask(plugin, () -> {
            for (int i = 0; i < BLOCKS_PER_TICK; i++) {
                if (!iterator.hasNext())
                    return;
                iterator.next().setType(blockTypes.generateRandom());
            }
        }, 0L, 1L);

@kindred valley

[humble tulip]

are you new to java?

[dense crow]

not that new, but still in learning

[humble tulip]

tbh, if you're trying something like this for 2 months and havent found a solution, something is wrong with how you research stuff

what have you tried?

[dim palm]

do an InteractEvent and if the block is door and the player has the specified permission allow the event but if the player doesnt have permission cancel the event

[dense crow]

yeah

but got the problem

how do i set the permissions to the doors

[humble tulip]

huh?

what do u want the permission nodes to look like?

[dim palm]

if (player.hasPermission("door.perm")

[lost matrix]

Problem here is that the task will keep running even when the iterator is empty.

[dense crow]

i thought its like u click it with a tool, the position of the door getting saved and when the players tries to click the door the locations getting checked and if he got the permission then he can open if not its getting cancelled

[humble tulip]

oops

[dim palm]

what

[humble tulip]

just need to add a cancel if it doesnt have a next

[dense crow]

my english isnt the best so sorry when u cant understand it very well

yeah but how do i register them

[dense crow]

hmmm but how do i store them to different doors? like i want that one door i can open the other door only other player can open...

[earnest forum]

this unobfuscates nms

search the class and then the method

tells u moj mapping, obfuscated and spigot mapping

is it possible to cancel jumping entirely? with or without nms?

[kindred valley]

[brave sparrow]

Very high jump boost

[lost matrix]

put a very high jump boost on someone

[subtle folio]

That’s buggy

[dim palm]

PlayerToggleFlightEvent?

[subtle folio]

i tried calculating and canceling it

[brave sparrow]

Does not get called every jump

[subtle folio]

That could work

[brave sparrow]

The high jump boost is the best strategy

[kindred valley]

Yeah i had many problems with move event too

[subtle folio]

i see

is it possible to replicate or fire the wardens sonic boom?

[lost matrix]

Im not even sure how the sonic boom is implemented.
Its not an entity so im assuming that its just a particle effect.

[subtle folio]

hmph i’ll do some digging and maybe some ray tracing then

[cunning shard]

what is the "prefix" thing and how do i use it

nvm

[dense crow]

okay im back, got it to save the location and owner, but now, how do i save multiple locations for one player?

[lost matrix]

I have no context but: Save a list or set of locations.

[subtle folio]

Map<UUID, List<Location>>

[lost matrix]

Nested collections is a bad code smell. I would advise against this. Encapsulate the List in a data object.

[subtle folio]

Not really..

For his use case it’s perfectly fine, no?

[lost matrix]

Referring to?

Its not perfectly fine. Its unclean.

It exposes data structures.

[subtle folio]

Unclean, how would you store it then?

[lost matrix]

Map<UUID, SomePlayerData>

[subtle folio]

In an object..

[lost matrix]

And SomePlayerData strongly encapsulates a List<Location>

[subtle folio]

Sure, kinda is the same thing though?

I guess not really.

i take that back

Object is better bc you can have multiple fields other than the said list if you wanted.

Alright

[dense crow]

zx

ty

[subtle folio]

Don’t use that,

[dense crow]

okay

[subtle folio]

use what 7smile7 said instead

[lost matrix]

That is just a nice effect. But the real benefit is that the list is no longer exposed which makes your code
just so much more robust.

[subtle folio]

Robustion

[glossy venture]

i wouldnt care about the list being exposed but it is nice to have the flexibility to add new fields

[lost matrix]

I would care very much if the list was exposed... It makes working with this data faster and cleaner.

Why would you write fragile code if you could just not?

[glossy venture]

yeah using a player data object is better

[lost matrix]

*And you could let the data object implement ConfigurationSerializable which means you can just put .set("some.player.path", playerData) it in a FileConfiguration.

[dense crow]

like that?

[lost matrix]

Sure, kind of like that

how can i get the ender dragon's fireball target ?

i could get the ghast target

[dawn plover]

how do i give players permisions tags
only thing i can find is player.hasPermission("blabla")

other thing, how do i check for multiple events at once

so like, something happens when i shift and right after that

[echo basalt]

Pretty sure it just fires in a general player direction, with no tracking of who it was meant for

Ghast#getTarget returns the ghast's target because a ghast is a single-target "simple" entity

The dragon has phases

[small current]

so can i get the direction ?

[echo basalt]

Uhh yeah

DragonFireball#getDirection / Fireball#getDirection

[quartz basalt]

if i have a plugin thats made for 1.18 but a player uses it on 1.19 how can i make it so the player can use 1.19 blocks if they are on 1.19 even though the plugin is in 1.18?

[echo basalt]

Material#valueOf should consider that

[dawn plover]

how would i add permision to players

or check for multiple events that happen right afther eachother

[tender shard]

you just listen to all of those events?

Hello, did anyone know how to get vector from some location (x,y,z) to some player?

[frosty tinsel]

I think you can just subtract the two locations and that's the resulting vector

[hushed pawn]

thank you

[tender shard]

just subtract the destination from the origin

[hushed pawn]

okay, now how to make hit from this direction looks like actual hit from player? xd

[tender shard]

normalize the vector and you should be fine

to normalize a vector, just divide it through it's length. there's probably a normalize() method too

should be

[tender shard]

You gotta normalize the resulting vector lol

[hushed pawn]

its not even get better

i can still fly into the sky

[eternal oxide]

what? that is a unit vector from the player to the destination

[hushed pawn]

i also tried swap it

[lost matrix]

What are you trying to achieve?

[hushed pawn]

emulate hit by player

i am trying to do a thing called reduce bot

[mortal hare]

Bukkit.createInventory(InventoryType.BEACON) is broken

beacon functionality is completely broken

it could be on purpose tho because there's no range

[eternal oxide]

Why are you creating an inventory instead of getting teh beacons inventory?

[mortal hare]

because i want to use Beacon's ui

as a GUI

[eternal oxide]

ah

[mortal hare]

Bukkit.createInventory() implementation is very hacky in spigot

but it works

it creates a Class CraftInventoryCustom which creates spoofed container class for NMS to delegate NMS container classes

the problem is that packet handling do not check if craft inventory is custom

basically packets gets handled only if container type is derived from the NMS container type

which is not the case with wrapped MinecraftInventory class since it directly implements Container interface

i bet enchantment table is broken too unless its patched inside delegation class

lemme check

[visual tide]

iirc yes

anvil, etable and beacon were all broken af when i last checked

[mortal hare]

anvil works fine

at least on paper

[visual tide]

*on spigot

[mortal hare]

it has a patch inside CraftContainer

class to fix the anvil and crafting table

but not the enchanting table and the beacon afaik

oh man

Enchanting table is even more broken LOL

lemme record it

[tardy delta]

hmm buggy asf

[mortal hare]

Beacon GUI dont even provide default name when opened

beacon name is displayed by hovering the buttons normally

but instead i get container.beacon there

[river oracle]

Are you building everything from ground up with containers or using bukkot createInventory

[mortal hare]

I am patching this from ground up for myself but what im showing is the functionality of Bukkit.createInventory()

[paper viper]

Nah

Yeah

[river oracle]

Do you think you could write to the registry for custom inventory sizes it's something I've looked at in the past but was unsure about

I tried but one interface I needed to use as a parameter was private and nested

[mortal hare]

this could be fixed easily by adding instanceof CraftInventoryCustom.MinecraftInventory minecraftInventory && minecraftInventory.getType() == InventoryType.INVENTORY_TYPE_OF_PACKET into each guard clauses of ServerGamePacketListener class

[tardy delta]

i'm currently having a KingdomsPlayer class, which is basically a wrapper for a player which provides some extra stuff etc. in my opinion, it would be better to store a WeakReference<Player> internally instead of callin Bukkit.getPlayerExact every time
so is this a good way to set the player object when its actually available, (async pre login event doesnt have a ::getPlayer)

[mortal hare]

since packet handling except for slot handling are being ignored for the most past

[mortal hare]

Inventory sizes are not being stored in registries

InventoryTypes are

[river oracle]

Ahhh

So even if you create another type there's no point since it can't be displayed by the client

[glossy venture]

yeah but make sure to make it weak

[mortal hare]

NMS Container class and in some places Menu with SimpleContainer inside store the size data

[tardy delta]

yee

i also have a logout method which stops sending an actionbar and stuff and clears the reference

[river oracle]

It'd be impossible to have like a 5 slot inventory right?

[glossy venture]

hopper yeah

[river oracle]

Eh bad example

Like 6 or something that's not pre existing

[mortal hare]

you could but it would desync from the player's client

unless there's menu type which provides 5 slots

[river oracle]

Hmmm interesting

[mortal hare]

closest i can think of is hopper

[river oracle]

Would you think it'd look fucky or just break

[mortal hare]

just use Bukkit.createInventory(InventoryType.Hopper)

and you're fine

[river oracle]

I'm just talking about non-conventional inventory sizes

[mortal hare]

for slot operations this method is not broken

[mortal hare]

there's no way to make those, unless you use some kind of resource pack to hide the other slots

and make implement a new class

in order to desync other slots

[river oracle]

I've been curious about that for a long time when overlaying a resource pack title on an inventory what stops the other slots from ruining tje effect via shift clicking etc

Do you have to send packets on click to make it seem like there's no free slof

[tardy delta]

myes
