[dawn flower]

the Block one is getState tho

[chrome beacon]

you don't need the block you can get it directly from the world

[dawn flower]

wait why do people fork spigot for certain servers, wouldn't you have the same stuff as using NMS

[shadow night]

yeah, why

[dawn flower]

i mean you can do some extra stuff like crash detection unlike spigot but that's pretty much all that i can think of

nvm u prob cant do crash detection\

[shadow night]

why

tyr {}

sec

[nova bolt]

it worked in the past

[dawn flower]

add it as a dependency

[shadow night]

try {
    new MinecraftServer().run();
} catch(Exception err) {
    LOGGER.error("Crash detected!", e);
}
``` looks like a bad idea but it's a crash detection lol

[lost matrix]

[shadow night]

what

[dawn flower]

smartest person in the world

[shadow night]

bukkit is an API, craftbukkit is the implementation of bukkit, spigot is a fork of bukkit, paper is a fork of spigot

[dawn flower]

paper = bukkit + spigot

[lost matrix]

WorldGuard was primarily written for Spigot. It 100% works.

[dawn flower]

wait what?

i mean i know worldguard is pretty old but it was written for spigot?

[lost matrix]

I mean originally it was written for bukkit. They made it platform agnostic after a while.

[peak jetty]

why does this not work?

[shadow night]

mm, hardcoding locations

[lost matrix]

Because you didnt get the BlockState.
Also getting a World like that is dangerous

[shadow night]

everything in this screenshot is dangerous

[worldly ingot]

It's not the Block that's a Chest, it's its state

[peak jetty]

oh so like this? Chest chest1Level1 = (Chest) l.getBlock().getState();

[nova bolt]

ye but with /plugins appears with red and cant seem to find the ploblem

problem*

[lost matrix]

Think about Block just describing a position in the World.
It has no actual properties.

[lost matrix]

Did you install WorldEdit?

[remote swallow]

check startup logs

[peak jetty]

i changed it to this but it still didnt work:

Location l = new Location(getWorld("poi"), 67, 137, 79);
Chest chest1Level1 = (Chest) l.getBlock().getState();
chest1Level1.getInventory().setItem(1, new ItemStack(Material.DIRT));```

[lost matrix]

?notworking

[undone axle]

"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.

[peak jetty]

like it doesnt make the item in the chest dirt

[shadow night]

have you tried the magical thing called debugging

[lost matrix]

You need to call update(true) on the Chest after changing the state

[shadow night]

as well as googling

[lost matrix]

Any exceptions in console?

[peak jetty]

nope

[scenic sigil]

thanks

[peak jetty]

wait ima try use some loggers

[lost matrix]

Add a debug statement and check if your code is actually executed

[dawn flower]

u have to update

[worldly ingot]

Not when editing a state's inventory

Inventories are a bit special :p

[lost matrix]

Yea realized as well

[nova bolt]

yep

[remote swallow]

check startup logs

[lost matrix]

Then check the logs. If the plugin is red then there is a stack trace.

[peak jetty]

 else if (cmd.getName().equalsIgnoreCase("reloadpoiloot")) {
            getLogger().info("reload poi loot command called");
            // If it's a player and has plutotools.reloadpoiloot or if it's console
            Player p = ((Player) sender).getPlayer();
            if ((sender instanceof Player && p.hasPermission("plutotools.reloadpoiloot")) || sender instanceof ConsoleCommandSender) {

                getLogger().info("player has all permissions");

                Location l = new Location(getWorld("poi"), 67, 137, 79);
                Chest chest1Level1 = (Chest) l.getBlock().getState();
                chest1Level1.getInventory().setItem(1, new ItemStack(Material.DIRT));
                chest1Level1.update(true);

                getLogger().info("works");

            }
            return true;
        }```

still doesnt work for some reason

[lost matrix]

Are the debug statements being printed?

[peak jetty]

yeah

[lost matrix]

try l.getBlock().setType(Material.DIAMOND_BLOCK) and check if your chest is replaced by a dia block

[dawn flower]

does getInventory return a copy

[peak jetty]

yep the chest becomes a dia block

[dawn flower]

CraftInventory inventory = new CraftInventory(chest);

and

// The logic here is basically identical to the logic in BlockChest.interact

in CraftChest

[lost matrix]

Try addItem instead of setItem

[peak jetty]

if i do that it wont let me replace the existing item tho

and it doesnt let me set the slot number

[lost matrix]

Try it out pls

[dawn flower]

try Chest#getBlockInventory

instead of getInventory

[peak jetty]

tried it, didnt work

[peak jetty]

still doesnt work

[dawn flower]

and update

[lost matrix]

What version are you on?

[peak jetty]

1.20.1

[peak jetty]

yeah im doing that

Location l = new Location(getWorld("poi"), 67, 137, 79);
Chest chest1Level1 = (Chest) l.getBlock().getState();
chest1Level1.getBlockInventory().addItem(new ItemStack(Material.DIRT));
chest1Level1.update(true);```

[lost matrix]

Do you have any Listeners for the InventoryOpenEvent?

[dawn flower]

try to print a filled slot from the chest's inventory to make sure you have the correct instance

[peak jetty]

no i dont

[lost matrix]

What does your PlayerInteractListener do?

[peak jetty]

like this for example? getLogger().info(chest1Level1.toString());

[peak jetty]

just makes a new inventory when a player clicks on a compass

[worldly ingot]

I'm not 100% certain but wouldn't the update() override the inventory change?

[lost matrix]

That might be possible

[worldly ingot]

It's really the only thing I can think of causing issues

[peak jetty]

YES that was it thanks

[worldly ingot]

block states are a bit finnicky

[nova bolt]

it says this

[lost matrix]

There you go

[nova bolt]

do i need to change the server version

[chrome beacon]

yes

[lost matrix]

Or use an older version of wg

[chrome beacon]

^^

[nova bolt]

where can i find those?

[lost matrix]

Why are we giving server help in the development channel btw?

[chrome beacon]

no idea

[lost matrix]

#help-server

[nova bolt]

k

[worldly ingot]

You're also using Paper 😛

So in the future, even if it's not specifically server software dependent, it's best you ask for support in the Discord server of the server software you're actually using

[agile hollow]

how can i brodcast all the args after the 0?

[lost matrix]

By index iterating but starting at 1 instead of 0.
Or by creating a sub-array from 1 to end and then joining the Strings.
Probably a dozen more approaches for this

[agile hollow]

like a done a command that work like /brodcast alert - - - - i want all the args after the "alert" then after the args[0] to show up in the brodcast

[peak jetty]

how should i make a list of contenents (multiple items) to go into a chest?

[lost matrix]

Are the slots important or do you just want to add them to the chest?

[peak jetty]

the slots are important

[lost matrix]

In that case you should probably just use setItem().

Alterantive would be setContent() by passing an ItemStack[] to the Inventory.
But this expects an array of the exact size as the inv

[lost matrix]

By index iterating but starting at 1 instead of 0.
Or by creating a sub-array from 1 to end and then joining the Strings.
Probably a dozen more approaches for this

[peak jetty]

well i want to have multiple chests with the same contents so i dont really want to repeat setItem() for all of them

[lost matrix]

Write a method then...

[lilac dagger]

have a method that takes an inventory as parameter

[lost matrix]

Writing reusable code is key. Nobody wants DRY code.
DRY=
Dont
Repeat
Yourself

If you find yourself copy pasting code, then its time to think about how
to write reusable code.

You could for example create a method

public void fillInventoryWithGarbage(Inventory inventory) {

}

which fills an inventory, and then call it for as many different invs as you want.

[lilac dagger]

we all like WET code around here

||I hope nobody's offended haha||

[lost matrix]

[twin venture]

[peak jetty]

alright thanks

ill try it out

[quiet ice]

= Will eat tables

[lilac dagger]

lol, chatgpt found the best answer 'Write Everything Twice'

[peak jetty]

do i need to specificy how big the inventory is?

[lilac dagger]

it can't be bigger than 54

but the inventories have to be the same since the content is?

[peak jetty]

so if this is my content say:

public void contents1Level1(Inventory i) {
        i.setItem(1, new ItemStack(Material.ENDER_PEARL));
    }```

how do i set it to be in the chest? `chest1Level1.getBlockInventory().setContents();`

[lost matrix]

You pass the chests inventory to the method...

[lilac dagger]

exactly ^

now it depends if that's the correct inventory, blockstate usually works differently than you'd assume

[peak jetty]

like this? contents1Level1(chest1Level1.getBlockInventory());

[lilac dagger]

yeah

[peak jetty]

alr

[worthy star]

whats best way to check when player enters a region with worldguard api?

[rough ibex]

I suppose you should ask enginehub people.

[worthy star]

whats that?

[rough ibex]

The people who make worldedit and worldguard

[worthy star]

oh you mean the creators of it

[rough ibex]

Yes; they would know their API more than us collectively.

[worthy star]

ok

[rough ibex]

good luck

Running 1.8 means you have to init your driver Class.forName(...

wdym?

i do it

        this.connection = DriverManager.getConnection("jdbc:sqlite:"+file);
        Class.forName("org.sqlite.JDBC");
        createTable();
    }

1.8....

please

[agile hollow]

what?

[rough ibex]

1.8 is what, 8 years old

why are you still targeting it

[agile hollow]

best version for me :D

[rough ibex]

not for anything else lol

[agile hollow]

September 2, 2014 the release of the 1.8 XD

10y ago

[rough ibex]

yeah legacy

[agile hollow]

what is the better the 1.20?

[rough ibex]

yes

1.20 is latest and updated

[agile hollow]

i use both

[remote swallow]

what is it even meant to do

[spare hazel]

a list of blocks with their data so we can see if a player has the right requirements to break that block or no

and their custom drops

[remote swallow]

a) dont use new BlockData but Material.VALUE.createBlockData() and b) why do you even need block data here, just use a material to material map for drops

[bleak moth]

Hi, my plugin has a big problem, i write to a file to get information about a score, the score is binded to a player and saved to the file. I have a command to set the score of the player, but when i do that or edit the file myselfe it doesnt change on save or it seeems to get it old value back after some time. I use a .yml file

[echo basalt]

Show code

solid chance you aren't saving the file

[spare hazel]

no its not just that

and the BlockData is class of my plugin

[bleak moth]

its multiple files so not easy to post all here, is a github link ok?

[echo basalt]

Go for it

[lost matrix]

Just editing a file wont change the values in memory.
If you edit a file, and save your memory values back later, then your edited file obviously gets overridden.

[spare hazel]

question:

private static

which one is better

[lost matrix]

latter

better?

[bleak moth]

oh sry wair

[bleak moth]

now its public

[inner mulch]

when i want to have placeholders, but they all can have completely different parameters. How would I implement that, an interface doesnt work as the placeholders all have different params?

[echo basalt]

Cool, I'd like to suggest we do some restructuring so this code makes a bit more sense

[lost matrix]

Do what PAPI does.
Use a separation character (like a dot) and then split the placeholder.

[echo basalt]

if you want a good data structure for placeholders keep in mind they're basically like a little scripting lang

[inner mulch]

yes i thought about this, but then, when for example using it in a config file you cannot fill it out correctly?

[astral scroll]

i need the actual durability of a picaxe, but ItemStack#getDurability is deprecated, whats the new method to get that?

[lost matrix]

Hm?

[echo basalt]

Casting to the ITEMMETA Damageable if possible

[inner mulch]

you cant %myplaceholder.<playersuuid>%?

in code it would work

but not in a config

[bleak moth]

I know that this isnt good written code its not really made to be easy to understand. Iam still learning. But I apreaciat every help

[lost matrix]

Example:
Your separation char is #
Your placeholder key is chance
It has one parameter:
%chance#<value>%
Then a placeholder in a config could be:
"%chance#15.25%"

In your implementation your simply parse for all Strings between two %. Then you split it at #.
The first entry is your placeholder key, the other entries are your String[] args like you would have in a command.

[inner mulch]

yes this would work, but think about a config file about a playerscoreboard then i want to implement %money#playersuuid% i cannot get the player uuid from the config, this system is great for devs, but not for configs

[lost matrix]

[inner mulch]

what?

placeholder needs player specific input, how am i gonna get player specific details

[astral scroll]

so cast the ItemMeta do Damageable and then do .damage()?

[echo basalt]

getDamage on the itemmeta damageable yeah

[inner mulch]

Damageable idk = (Damageable) itemmeta;

[echo basalt]

.damage is probably a method from the entity damageable

[astral scroll]

ohh

inventory.meta

cool

[lost matrix]

Please give another example. Yours doesnt make sense in the first place.
Nobody would write the score of a single specific UUID in their scoreboard...

[astral scroll]

do people like kt around here?

[inner mulch]

thats why this system is flawed

[alpine urchin]

i dont

but im closed minded

[inner mulch]

you can only have the data of a single specific uuid with this kinda approach

[lost matrix]

Remember that your placeholder always has the viewer as its first context:

public String evaluate(Player viewer, String placeholder, String[] args)

And then you simply treat it the same way as bukkit commands

[river oracle]

Anyone know how to fix MockBukkit just like not running 🥲

[astral scroll]

whats MockBukkit for?

[slender elbow]

mocking bukkit

[inner mulch]

ok

[slender elbow]

you're welcome

[river oracle]

wow you are a real intellectual

someone should give you an award

[slender elbow]

I am aware

[lost matrix]

Ok but that is simply not a viable example.
If you wanted to have a toplist in your scoreboard, then your placeholder would look like this:
%topkills#<rank>%
With a config which might look like this:

score:
  - "%topkills#1%"
  - "%topkills#2%"
  - "%topkills#3%"

Its all up to the developer to provide usable placeholders

[inner mulch]

this would work, but i was thinking about not having the player as a forced param, that why i was asking how the system is gonna work

[remote swallow]

[lost matrix]

Ah ok. Yeah without a viewer context it wont work.
Its like trying to let someone send a command, but you dont have the command sender in your method.
Try getting the command sender now for context. Cant really pull him out of thin air ^^

[inner mulch]

ok

what does a entity with no ai does in its tick method, and how expensive is it compared to a entity created with packets?

[astral scroll]

to set durability what can i do?

[lost matrix]

There is def a difference between a purely virtual entity and a physical one without ai

[lost matrix]

Cast ItemMeta to Damageable and call setDamage()

[inner mulch]

So a big performance difference?

[astral scroll]

k

[lost matrix]

Depends a bit on what you are doing
Salvatíoné

[astral scroll]

i just wanna

subtract

10 from the actual durability

so i can do

setDamage(getDamage+10)

I want to create entities which are only seen by certain players and ther dont do anything except exist, packets afe perfect but i dont want to use them, bevause they are not maintainable

[radiant vessel]

I am trying to rework a plugin called "FactionMobs" which is deprecated, and the point of it is to allow players to spawn mobs are allied with their Nation in Towny, now I have no problem with any of that except one part, and it is how do I make mobs attack a specific player yet be friendly to another? Does anybody know of a Library made for controlling mobs and their behaviors? If not, then I would appreciate if I was given a simple Idea from one developer to another on how to do something like

I can know who is the enemy, and I can know who is supposed to be friendly, and I know how to do everything else it's just the mob control part I can't get

[young knoll]

EntityTargetLivingEntityEvent

Iirc

[radiant vessel]

But wouldn't this make it so the mob would still attack the ally of it?

Like this seems like it just readjusts the pathfinding

ahh whatever I will try it

Thanks for the idea

I appreciate it

[young knoll]

You can cancel it under certain conditions

[short pilot]

Intellectuals, i require your help once again
how can you get generic attack damage attribute from an entity? I want to get the total damage a player can deal with their main hand plus effects and enchants, but i'm not sure if generic attack damage alone gets this

[young knoll]

It does not

There is no api to get that easily

[short pilot]

ok so getattribute works

and i'm grabbing GENERIC_ATTACK_DAMAGE

[astral scroll]

can i send kt code or i will not receive support

[short pilot]

from here, how can I check for sharpness enchant and add that to the damage?

[young knoll]

Get the held item and get the level of sharpness

Then do the maths

btw

item.durability = (amount you want to subtract)

[topaz cape]

player.launchProjectile(ThrownPotion.class, new Vector(0, 0, 0)).setItem(this.healItem);

anybody know a way that makes it look if i threw the actual potion not a water bottle

[remote swallow]

that damageable varable can be defined as just item.itemMeta s Damageable

without any parenthesis

[drowsy helm]

launchProjectile will return ThrownPotion instance which you can change the metadata iirc

[lilac dagger]

probably the healitem wasn't properly defined

[drowsy helm]

yeah what is healItem

[topaz cape]

it is defined, and its a heal potion whenever it hits the ground

however when its shot its visually is still a water bottle

[topaz cape]

its the heal potion found in the inventory xd

[drowsy helm]

can you show the whole code snippet

[topaz cape]

        if (this.shouldHeal()) {
            if (NPCUtil.consumeItem(npc, this.healItem)) {
                if (healItem.getType() == Material.POTION) {
                    final int heal = healItem.getDurability() == 16453 ? 2 : 4;
                    bot.setHealth(Math.min(bot.getMaxHealth() + heal, bot.getMaxHealth()));
                    bot.launchProjectile(ThrownPotion.class, new Vector(0, 0, 0)).setItem(this.healItem);
                }
            }
        }

[lilac dagger]

i remember the colors of the potions were off for me

i had to do something weird to make them work

[topaz cape]

I think creating the NMS entity would fix it

but im asking if there is a bukkit api for it

maybe somehow convert the potion to an entity

nah i think its just creating an NMS entity

no need to get to packets

alright

[spare hazel]

how can i get the friendly name of a material

[drowsy helm]

the friendly name?

[spare hazel]

and if your hand is empty, will player.getInventory().getItemInMainHand().getType() return null

[spare hazel]

DIAMOND_SWORD: Diamond Sword

[remote swallow]

split on _ get first char, uppercase and replace

[drowsy helm]

getItemInMainHand will be null, yes

and yeah, no method for it, either use the itemstack to get displayName from meta or do waht Epic say on material

[remote swallow]

display name wont exist for un renamed items

[spare hazel]

guess its time to get googling

or use chatgpt that might be a better aproach

[remote swallow]

make something using what i said

using chatgpt for everything wont help learning

[drowsy helm]

you didnt google before you asked on here?

[spare hazel]

i barely know how to format text in java

[spare hazel]

nah its just easier

[remote swallow]

you really should be googling before coming here

[echo basalt]

blocked.

[remote swallow]

because thers a solid chance sometimes the answer you are looking for takes 1 second to find

[spare hazel]

 public static String getFriendlyText(String text){
        //Credits To My Bro ChatGpt
        String[] words = text.toLowerCase().split("_");
        StringBuilder result = new StringBuilder();

        for (String word : words) {
            if (!word.isEmpty()) {
                result.append(word.substring(0, 1).toUpperCase())
                        .append(word.substring(1))
                        .append(" ");
            }
        }

        String finalText = result.toString().trim();
        return finalText;
    }```

[glad prawn]

just return then, why temp var

[spare hazel]

alr

[final wharf]

how can i get the block under the player and set it to a random block?

[sand spire]

        Block blockUnderFeet = blockAtFeet.getRelative(BlockFace.DOWN);```

[final wharf]

thanks

[obsidian wolf]

anyone know how to code on java? need help with a simple custom item

[tawdry echo]

https://github.com/Xemuain/testing what do you think about this GUI system?

[drowsy helm]

everyone on this channel knows how to code in java, whats your question exactly

[obsidian wolf]

great, so basically

im trying to make a custom item and I coded everything for it using a tutorial

however for some reason when i load into minecraft the actual texture doesn't load.

[drowsy helm]

    static {
        Bukkit.getPluginManager().registerEvents(new Listener() {
``` this is a big no-no

[remote swallow]

im very sad to tell you no one here knows how to code in java and were all fake

[obsidian wolf]

can I send you my code and show you what i mean?

[drowsy helm]

?paste

[undone axle]

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

[drowsy helm]

put it on that

[obsidian wolf]

Alright

then what

[final wharf]

send it lol?

[obsidian wolf]

like.. how

lmfao

{
"parent": "minecraft:item/handheld",
"textures": {
"layer0": "minecraft:item/diamond_sword"
},
"overrides": [
{"predicate": {"custom_model_data": 40000}, "model": "minecraft:item/kingsword"}
]
}

and

{
"parent": "minecraft:item/handheld",
"textures": {
"layer0": "minecraft:item/kingsword"
}
}

separeted into 2 files ofc

[tawdry echo]

i mainly care about the fact that a new inventory is created for each player and the example of using Menu.class will be a burden for about 200 players

[lost ledge]

Is there some better way of checking if the server runs raw bukkit, spigot or any other fork than doing Class#forName?

[obsidian wolf]

i made the texture for it as well if you need me to send that

[drowsy helm]

@tawdry echo

                inv.getListeners().stream()
                        .filter(listener -> listener.getEvent() == InventoryDragEvent.class)
                        .forEach(listener -> ((GuiListener<InventoryDragEvent>) listener).run(e));

could be replaced with a for loop and if statement, will be a lot more performant

The use of the gui map is good

but yeah, move that static listener bs elsewhere

[drowsy helm]

That is a non negotiable, a static registration of listeners WILL break

and it breaks bukkit conventions

[obsidian wolf]

[drowsy helm]

so you want to know how to apply custom model data?

[final wharf]

but now how do i set the block to a random block

[obsidian wolf]

mm.. I guess so? is there anything wrong with the code because it just doesn't work... I have a custom texture pack for it aswell.

[remote swallow]

by a wild chance, are you using plug man or /reload confirm

[obsidian wolf]

supposed to show a png of a sword i made

[tawdry echo]

but after change registering listener it its will all ok?

[spare hazel]

nope

[obsidian wolf]

but its just a normal diamond sword

[remote swallow]

print the map before you call line 53 block break handler

[spare hazel]

how to print a map in a human readable format?

[drowsy helm]

just an fyi this has nothing to do with java, it's minecraft resourcepack stuff.

but you're 100% the custom model data is applied to the item?

[remote swallow]

calling println will tostring it for you

[drowsy helm]

and is kingsword in the item directory

[final wharf]

found out how thanks 🙂

lets move to #help-server @obsidian wolf

[obsidian wolf]

alright

[spare hazel]

wird

weird*

its {}

how would that be

[remote swallow]

double check you are actually registering the join event

and make sure your restarting

[spare hazel]

oh

[final wharf]

also forgot a ;

so i did that

but

i dont know what else to put

[spare hazel]

//Register Stuff
        getServer().getPluginManager().registerEvents(new BlockBreakHandler(), this);```

Proof That Im Blind:

```java
public void registerHandlers() {
        getServer().getPluginManager().registerEvents(new BlockBreakHandler(), this);
        getServer().getPluginManager().registerEvents(new PlayerConnectionHandler(), this);
    }```

thanks btw Epic

[final wharf]

@sand spire sorry for ping

nvm

i think i did it

    @EventHandler
    private void onPlayerMove(PlayerMoveEvent event){

        List<Material> blocks = new ArrayList<Material>();
        for (Material block : Material.values()) {
            if (block.isBlock()) {
                blocks.add(block);
            }
        }
        Material randomBlock = blocks.get(new Random().nextInt(blocks.size()));

    }```

[drowsy helm]

you'll have to get an array of block materials and get inbetween 0 and the length

pre-bake the list/array

orelse you are calling that each time ap layer moves

[sand spire]

I never tried to get a random block but I guess you can add every block or material to an arraylist and use Random to get a random index

[spare hazel]

and this code changes the block every time the player moves, not moves to a different block so this can cause huge lag

[final wharf]

eh

its just for fun

and it also doesnt work

do i have to register the event even if its in the main class?

[glad prawn]

private method 🤔

[drowsy helm]

you have to register the main class itself

[final wharf]

well its in the main class

[drowsy helm]

even if it is JavaPlugin

[spare hazel]

when i read this: Minecraft But Random Blocks Spawn Under Me Every Time I Move -Shorts Youtuber

[final wharf]

oh

[final wharf]

No

[drowsy helm]

but that code is gonna lag your server

[final wharf]

im a begineer and a friend of mine who knows java told me to try and do this

to learn

[spare hazel]

alright

but make sure to prebake the list and change the block only if he switched to a new rounded xyz location

[sand spire]

Maybe something like this will work

List<Material> list = List.of(Material.values());
            Material material = list.get(0); //random logic
            location.getBlock().setType(material);```

[final wharf]

that works

i just didnt register it

[drowsy helm]

.

[final wharf]

its for testing purposes

still not working

lol

[spare hazel]

if you are learning you need to also learn to optimize your code @final wharf

[glad prawn]

?notworking btw

[undone axle]

"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.

[final wharf]

well yeah

but for a few minutes it doesnt hurt

[sand spire]

theres nothing in the arraylist

[final wharf]

"of" is underlined

[lilac dagger]

java 8 i assume?

[spare hazel]

old java version

[final wharf]

java 21

[spare hazel]

bump it up

[final wharf]

im using java 21

[glad prawn]

Point to it and see what it says?

[spare hazel]

check the problems tab of your editor

[lilac dagger]

then you imported the wrong List

[spare hazel]

and right click on it

[spare hazel]

yeah that

[lilac dagger]

it is the wrong version

[final wharf]

How?

[spare hazel]

click on it

[final wharf]

i created the plugin with java 21

[final wharf]

i did

[spare hazel]

reload maven

[sand spire]

You can try List<Material> blocks = Material.values(); then check the error and see what intellij suggests, for me it suggested List.of

[glad prawn]

can use Arrays.asList

[final wharf]

still not working

what

[sand spire]

List<Material> blocks = Arrays.asList(Material.values());

[remote swallow]

thats some spoonfeeding and a half

[final wharf]

yeah lol

i kinda understand better from spoonfeeding(personally)

[sand spire]

xdd

[final wharf]

so like this?java Location location = event.getPlayer().getLocation(); List<Material> blocks = Arrays.asList(Material.values()); Material material = blocks.get(0); //random logic location.getBlock().setType(material);

[astral scroll]

how can i destroy an itemstack?

like just

disappear it?

[pseudo hazel]

I mean sure, you understand just this very specific usecase and way to do this very thing, but its not really applicable to find your own solutions later down the line 😛

[final wharf]

somehow i do

dont know how

[sand spire]

you still want logic to filter the blocks

[glad prawn]

doesnt u want the block that is under the player

[final wharf]

Oh yes

Sorry

I can fix it from now(maybe)

Thanks

[sand spire]

i got it to work xd

if you can't figure it out I can send you

[spare hazel]

check if its air and if it is then return

you also need to make sure the block is solid with isSolid

[sand spire]

got it, also isOccluding to only get blocks that sufficate you so no slabs and random smaller blocks

[spare hazel]

yeah right

[spare hazel]

were turning this guys random project to a full on minecraft gamemode XD

[sand spire]

xdd

[spare hazel]

and maybe use mfnalex's PDC for blocks so we dont replace already randomized blocks

[sand spire]

😳

[spare hazel]

and maybe replace the block with its original block after like 100 seconds

[sand spire]

https://pastes.dev/poE47TS53f

[spare hazel]

an make sure the player cannot break non random blocks

[sand spire]

was fun to code something that doesn't give me a headache 💀

[flint coyote]

if you do that you don't need a pdc. Could use a Set and then reset on restart/reload (or after 100 seconds) - whatever comes first

[sand spire]

both would work, one would just be persistent on restart

[spare hazel]

no i meant that we need pdc to make sure they dont break non random blocks and we dont replace random blocks

[flint coyote]

If they stay randomized forever I'd agree on using pdc. But if you wanna reset them after a short time it's not required to make it persistent

[sand spire]

that would be cool if they turn back like disco floor

[spare hazel]

gotta put random blocks smp on my game mode todo list for my server

time to push to master and rest

[sand spire]

https://pastes.dev/RMnetngHOE @spare hazel epic disco floor plugin! imma keep this on while testing my stuff and hope i don't regret xd

probably very bad for performance xd

[spare hazel]

i cant understand anyhting, somehow

maybe im stupid idk

[sand spire]

its just messy

[spare hazel]

nah im stupid

[spare hazel]

Bukkit.getScheduler().runTaskLater(CustomItems.getINSTANCE(), () -> {
            if (list.isEmpty()) {
                return;
            }
            
            BlockState block = list.get(0);
            list.remove(0);
            block.getLocation().getBlock().setType(block.getType());
        }, 100);```

what is this supposed to do

[sand spire]

after 100 ticks it sets the block back to the old block

[spare hazel]

oh cool

[sand spire]

it breaks randomly but whatever lmao

[spare hazel]

make sure the chunk is loaded

@sand spire

[sand spire]

ah

[valid burrow]

anyone got a code snipped for testing if a (list of) itemstack(s) fit in a players inventory

you could clone inventory and then check addItem.isEmpty

itis b

because the error is happening in the BeforeEach method

when I call MockBukkit#mock

difference between #addDefault and #set in FileConfiguration

I assume addDefault doesn't overwrite existing data, and set does

right?

[ivory sleet]

Default is like a default value

[cinder abyss]

[agile anvil]

It doesn't even write data. It's just on memory, if the entry doesn't exist in the file it will return that value

[warm forge]

Hello there, I was wondering how I could update the victim's scoreboard inside the if (killer != null) in my onPlayerDeath script. I tried importing the code below into it but it won't work.

        int victimKillStreak = killStreaks.getOrDefault(victimId, 0);
        int limitedVictimKillStreak = Math.min(victimKillStreak, 5);
        ChatColor victimKillStreakColor = getColorForKillStreak(limitedVictimKillStreak);
        String coloredVictimKillStreak = victimKillStreakColor + String.valueOf(limitedVictimKillStreak);
        victim.setPlayerListName(victim.getName() + " " + victimKillStreakColor + "[" + coloredVictimKillStreak + "]" + ChatColor.RESET);
        updatePlayerScoreboard(victim);```





Full  onPlayerDeath script: https://pastebin.com/ZCfYshw8

[lost matrix]

Debug and check if the code is actually executed

[drowsy helm]

if (killerKillStreak + 1 >= 4) {

can be

if (killerKillStreak  > 3)

same goes for all the other ones

[cursive kite]

How can I detect when a player interacts with a hologram (packet armorstand)

[warm forge]

Like this? https://pastebin.com/NKZUT5w5 because it is still not updating victim's scoreboard when he is dying to the killer and the other way around as well.

[wet breach]

ah you want to know the secret to interacting with holograms

also known as touch holograms unless you meant something different

[lost matrix]

There are Three ways:

• When a player interacts, check his direction and calculate the vector and if it is close enough to the hologram line.
• Use an Interaction entity
• Use some invisible fake entity like a slime

All of those require a decent amount of work

[wet breach]

I can point you to a project that actually does implement touch holograms, not sure if you will be able to understand it though

https://github.com/frostalf/holoapi

[lost matrix]

Where do you listen for the touches?

Ah wait. Probably not a bukkit listener but a packet listener

ffs github

[wet breach]

Lol

https://github.com/frostalf/HoloAPI/blob/master/src/main/java/com/dsh105/holoapi/command/sub/TouchCommand.java

[lost matrix]

?

[wet breach]

you wanted to know where it was implemented, that is where it starts

then you found the event for it

[lost matrix]

I just wanted to look for "new HoloTouchEvent" and this would lead me to the actual impl

[wet breach]

there is no event in the Bukkit API that lets you listen for touches with holograms

so it has to all be implemented using some clever tricks 🙂

[lost matrix]

This is your own event you bob

I wanted to see where you fire it so that i can backtrack what you are doing

[wet breach]

yes I am aware its our own event never said we didn't have an event for it. Just that its completely custom is all

https://github.com/frostalf/HoloAPI/blob/master/src/main/java/com/dsh105/holoapi/api/HologramImpl.java#L673

[lost matrix]

Thats all i wanted to see 🙂
Why is this tightly coupled to the hologram?
Anyway thats what i did as well before Interaction entities where a thing. Slimes are most suitable for this.

[wet breach]

because this a plugin designed to be an API for plugins as well as providing features of its own

but that is the implementation which plugins shouldn't need

This API allowed you to do quite a lot of stuff

wihtout having to worry about implementing it yourself 😄

you could also let the API handle your holograms for you if you wanted, or do the opposite

either was acceptable

sadly 1.8 kind of killed it and I haven't had time to update this code base mainly because of how large it it is it took 3 devs to make this XD

[cursive kite]

Probably will use the fake slime

Or i guess real slime

[proud badge]

InventoryOpenEvent isnt triggered when the player opens their own inventory, anyone know a solution or a different event for it?

[drowsy helm]

there is none

[proud badge]

rip

[drowsy helm]

player inventory is completely client sided

next best thing is detecing when they click it, thats the closest you will get

[wet breach]

isn't the new way now that the players inventory is considered to always be opened?

if so, just check the inventory type they are interacting with

[worthy star]

whats best way to make a help cmd without putting each command? like
when player does a command without putting argument it sends the list of commands

[tall dragon]

if you have a proper command system that should be fairly easy

since each subcommand can then define its usage, & u can simply fetch the usage of each command and print it to the user

[worthy star]

i have a CommandsHandler interface that has

is it a proper command system?

[tall dragon]

yea so surely you have a collection of those somewhere

so u can just loop over that collection and get each commands usage right?

[worthy star]

okay

[lilac dagger]

could be better @worthy star

[worthy star]

but uhm well

i don't have a collection for them 🙂

should i like have a set map like Map<String, String> and put the command with usage in it?

[tall dragon]

how ru even invoking commands then

[worthy star]

i have a class that i extend in my commands classes and it has the stuff like execute() and checking permission,args,permission message,usage

[tall dragon]

how ru calling execute()

[worthy star]

not done yet

[tall dragon]

so the handler is just hardcoded in a command? ;d

[worthy star]

no?

i just put @CommandsHandler(stuff) at top and use the execute()

[peak jetty]

what does this error mean?

[tall dragon]

i would have a commandmanager that has a map<String,CommandHandler> that maps the main commands to a command handler, then u can easily invoke the command by checking the main command & u can also get all commands usages

[shadow night]

yeah has existed for quite a long time actually

never known

[wet breach]

naturally, its the same how people don't know about the conversation api

[tall dragon]

oh i know about that

i just think it isnt very good

[wet breach]

Well I think people know a bit more about the conversation api since I keep telling people about it when I get a chance 😛

however this is the first I have gotten the chance to talk about the help stuff

now, once this becomes a bit more known, it will be back to waiting on spreading some other unknown thing of the api 😄

[wet breach]

in one of your checks you are not checking if the command was the console

and you are assuming all commands are players

you can't cast console to player, so you should be checking if the sender is consolesender

[peak jetty]

this is what i have to check if its a console if ((sender instanceof Player && p.hasPermission("plutotools.reloadpoiloot")) || sender instanceof ConsoleCommandSender)

and then inside that if statement i got this:

if (sender instanceof Player) {
                    p.sendMessage(ChatColor.GREEN + "All POI's loot has been reloaded!");
                } else {
                    getLogger().info("All POI's loot has been reloaded!");
                }```

[wet breach]

well you are casting somewhere

IE you are doing (Player) sender somewhere

most likely before this check

[peak jetty]

oh yeah i am

[wet breach]

you need to do the casting after the check

[peak jetty]

alright 👍

wait but then i cant check if the player has the permission in the first if statement

since im using p.hasPermission()

[wet breach]

you can, you first do your check to see which sender is which. Once you know its a player, then do your casting and then do your permission check

you just have the order in the wrong arrangement is all

[peak jetty]

alr

[peak jetty]

why is this if statement not getting called when im moving from the world "world" to the world "poi" witha multiverse portal?

if (e.getTo().getWorld().equals("poi")) {
            getLogger().info("if statement called");
            Inventory savedInv = p.getInventory();
            getLogger().info(savedInv.toString());
        }```

[lost matrix]

A World object is never equal to a String object

[lilac dagger]

getworld get name

pretty sure the ide shows this as yellow

[peak jetty]

ohh ok thanks

how do i check if the location he tp'ed FROM was in a boundingBox?

[lost matrix]

Check if the location is inside the BoundingBox.
You first need to convert the Location to a Vector ofc. (toVector())

Hi, I want to store enchantment into my config (like this):
enchantment:
-SHARPNESS:2
-LUCK:3

But when getting enchantments from an ItemStack i found that Enchantment.getName()' is deprecated and i should use use Keyed.getKey() witch returns an NamespacedKey. I have no idea how NamespacedKeys work, please help

[chrome beacon]

A namespaced key contains two values

a namespace and a key

The namespace would be minecraft and the key sharpness

so minecraft:sharpness

[fair breach]

thank you i think i understand it now

Hello, so I'm trying to make an input GUI with fake (packet based) signs, I've tried a lot of different things for over 10 hours, but with ProtocolLib I never figured out how to change the text on the sign and with player.sendBlockChange + player.openSign i got the issue that the sign has to be real. All the information on google is outdated because signs have 2 sides now and the TILE_ENTITY_DATA packet takes different parameters, and everyone with same issue in this discord never figured it out.

My last idea is to have a real sign to open at some location far away which solves the issue of not being able to add default text to the sign but now I got the problem that if the sign is like 5+ blocks away it instantly closes.

So my question is if there is a way to cancel the closing of a sign when you move too far and if anyone has a solution for one of my other problems it would be amazing.

Stuff that doesn't work:
||player.sendBlockChange + player.openSign: https://pastes.dev/VKQNnbwnLQ Issue: java.lang.IllegalArgumentException: Sign must be placed||

||ProtocolLib player.sendBlockChange + (packets server to player) OPEN_SIGN_EDITOR & TILE_ENTITY_DATA: https://www.spigotmc.org/threads/signmenu-1-16-5-get-player-sign-input.249381/ Issue: signData doesn't hold a varInt anymore https://wiki.vg/Protocol#Block_Entity_Data||
This seems very complicated so thank you in advance to anyone who even tries to help me

[peak jetty]

why does getLogger().info("left after completion"); and getLogger().info("left before completion"); not get triggered in this event?

@EventHandler
    public void onPlayerTeleport(PlayerTeleportEvent e) {
        getLogger().info("player teleported");
        Player p = e.getPlayer();
        if (e.getTo().getWorld().getName().equals("poi")) {
            savedInv = p.getInventory().getContents();
            p.spigot().sendMessage(ChatMessageType.ACTION_BAR, new TextComponent(ChatColor.GREEN + "You entered the POI!"));
        } else if (e.getFrom().getWorld().equals("poi")) {
            getLogger().info("from poi");
            Vector fromLoc = e.getFrom().toVector();
            if (leavePyramid.contains(fromLoc)) {
                getLogger().info("left after completion");
                p.spigot().sendMessage(ChatMessageType.ACTION_BAR, new TextComponent(ChatColor.GREEN + "Congratulations! You completed the POI!"));
            } else {
                getLogger().info("left before completion");
                p.getInventory().setContents(savedInv);
                p.sendMessage(ChatColor.RED + "You exited the POI without completing it so your items didn't save.");
            }
        }
    }```

which mc version

[sand spire]

1.20.4

[rapid vigil]

As 7smile7 previously said, a World object can never be equal to a string

[peak jetty]

ohh i must have missed that thanks!

[tall dragon]

let me just try some stuff

[final wharf]

how do i get the block under the player?

[solemn meteor]

Whats a secure way to store data on a file and it not be changed by the user

[sand spire]

@final wharf

[final wharf]

thanks

so like this java @EventHandler private void onPlayerMove(PlayerMoveEvent event){ Player player = event.getPlayer(); Block blockAtFeet = player.getLocation().getBlock(); Block blockUnderFeet = blockAtFeet.getRelative(BlockFace.DOWN); Location location = event.getPlayer().getLocation(); List<Material> blocks = Arrays.asList(Material.values()); Material material = blocks.get(0); //random logic location.getBlock().setType(material); }

[sand spire]

@final wharf don't just copy it, try to understand it

[solemn meteor]

Do I just make a custom file format and use Serializable

I'll just do that nvm

[final wharf]

oh thanks

[tall dragon]

@sand spire managed to get this to work. but im pretty sure in 1.20+ its inpossible to have the sign be non visible, since the 1.20 client actually started immediately closing out of the sign if its far away.

I recommend jetbrains academy, but they're all decent

[inner mulch]

how do i hide an entity on defautl?

[sand spire]

Omg that is perfect I never managed to get the text on the fake sign, thank you for spending an entire hour to solve my problem. Can you send the code so I can see what I was doign wrong 💀

[tall dragon]

well there might be an issue, i used no protocol lib with mojang mappings

idk what ur using rn

[sand spire]

I tried it with protocollib & player.sendBlockUpdate

[tall dragon]

ru using mojang mappings?

[sand spire]

i'm not sure what those are but I'm using spigot methods & protocollib methods

[tall dragon]

bassically its a set of names that converts obfuscated methods to non obfuscated methods. then when you compile it automatically converts it all back to the obfucated version

ur will need that if u want to use my version

[sand spire]

Doesn't really matter, I just want the result

[tall dragon]

well here it is https://github.com/BertGarretsen/SignMenu/tree/master/src/main/java/me/shurikennen/signinput

[sand spire]

does that mean I need to import with maven or is it already in spigot just less beginner friendly

[tall dragon]

bassically u would need to do this https://blog.jeff-media.com/nms-use-mojang-mappings-for-your-spigot-plugins/

it would fk up any nms already present in ur plugin tho

[sand spire]

Only protocollib stuff or also spigot stuff? or just anythign with packets

this is the first time i'm consciously working with packets so doesn't really matter i guess

[tall dragon]

ur ide will tell u ;d

cuz mojang maps just changes how stuff is named

[sand spire]

alright tysm I'll let you know when i got it to work

EDIT: it works!

[sand spire]

edit: resolved

do i need to put it in my plugin folder or something

or is it my new server folder cause when I click on the spigotjar it starts generating stuff

or how do I forceupdate

is someone help me with ClientboundSetEntityDataPacket

[chrome beacon]

Did you forget the --remapped flag

[quaint mantle]

i dont know how to do the DataValue part

i am trying to make a armor stand invisible

[sand spire]

how do I even do that; java -jar BuildTools.jar --rev 1.20.4 --remapped

[chrome beacon]

yeah like that

[kind hatch]

Yes

[sand spire]

yeah but where

[chrome beacon]

in cmd

[sand spire]

oh in here <classifier>remapped-mojang</classifier> <!-- Important! -->

[chrome beacon]

or just open the BuildTools GUI if you can't figure it out

[chrome beacon]

no

[kind hatch]

The GUI has an option called Generate Remapped Jars

It'll also show you the command preview when you switch back to the main page.

You can always run java -jar BuildTools.jar --rev 1.20.4 --remapped if you have the jar file as well. :p

[sand spire]

oh so I should make it compile again with this on

[kind hatch]

Yes

[sand spire]

i have no idea how to run code anymore since I downloaded spigot 💀 it just always compiles now

[kind hatch]

It should be quick compared to the first run.

[quaint mantle]

how can i set the datavalue part in ClientboundSetEntityDataPacket

[chrome beacon]

Take a look at how Mojang uses it

[quaint mantle]

where can i do that?

[chrome beacon]

In the nms code

Just read the decompiled code

[sand spire]

It works now thanks yall!

[quaint mantle]

never done that before do u want me to just decompile minecraft?

[shadow night]

You already have

[quaint mantle]

o?

[chrome beacon]

If you're using Intellij just Ctrl click the class you want to open

[quaint mantle]

oh ok

[quaint mantle]

i did open the packet class but what do i do with it

[chrome beacon]

Now you can see the methods and stuff

if you can't find what you need keep digging through other classes

[quaint mantle]

mmm

any paticular thing to look for?

idk honestly

[chrome beacon]

if you can't figure it out you can always work with a packet library like ProtocolLib and PacketEvents

[quaint mantle]

        SynchedEntityData data  = stand.getHandle().getEntityData();
        data.set(new EntityDataAccessor<Byte>(0, EntityDataSerializers.BYTE), (byte) 0x20);

        ClientboundSetEntityDataPacket dataPacket = new ClientboundSetEntityDataPacket(id, data.packDirty());``` is it just this?

yk imma test it

omg yes

i am pro

this feels soo goood

whatt happens to a packet entity when i leave?

[young knoll]

It gets removed

[echo basalt]

What version are you using?

nvm you figured it out

[echo basalt]

The entity doesn't exist on the server, when you leave the client just nukes all the world data

[grim hound]

I send a buffer with a message

and the client

[grim hound]

automatically disconnects upon receiving it with this message

[echo basalt]

Show code

[grim hound]

a buffer is a netty ByteBuf

[grim hound]

it's scattered all over, but okay

@SuppressWarnings("UnstableApiUsage")
    public static ByteBuf createBuffer(PacketWrapper<?> wrapper, int initialCapacity) {
        if (wrapper.buffer != null) throw new AlixException("Incorrect invocation of NettyUtils.createBuffer - buffer exists ");
        wrapper.buffer = Unpooled.buffer(initialCapacity);
        wrapper.writeVarInt(wrapper.getPacketTypeData().getNativePacketId());
        wrapper.write();

        return (ByteBuf) wrapper.buffer;
    }

    public static ByteBuf constBuffer(PacketWrapper<?> wrapper) {
        return Unpooled.unreleasableBuffer(createBuffer(wrapper, 1));
    }

I create my static final ByteBufs using constBuffer

and the PacketEvents PacketWrapper

I do this mainly because I need to send packet "silently" so without the interceptor knowing

so I get the silent context the same way PacketEvents does:

@SuppressWarnings("UnstableApiUsage")
    public static ChannelHandlerContext getSilentContext(Channel channel) {
        return channel.pipeline().context(PacketEvents.ENCODER_NAME);
    }

I then invoke silentContext.writeAndFlush(somePacketByteBuf.duplicate())

[grim hound]

but it just gives me this

[grim hound]

the only real difference I found is that PacketEvent's allocates the ByteBuf with Channel#alloc#buffer

but upon investigating that just uses the default ByteBufAllocator

there's no console errors

[echo basalt]

Have you tried asking the man himself? @alpine urchin

[grim hound]

but I also don't know where to find the client-side decoder code, which could help me out

[grim hound]

yes

he said contact netty

[echo basalt]

lmfao rip

[grim hound]

and netty said contact the api

[grim hound]

he's also really against the idea of not fully using his api

and engaging with netty

        }
    }```

am i doing anything wrong releated to the TextComponent?

[echo basalt]

Yes

Appending colors like that is icky

[spare hazel]

let me do something else

wait

[young knoll]

You should be using the component builder

[spare hazel]

well textcomponent inherits from component builder

so whats the problem

public void increaseXP(int amount){
        xp += amount;

        TextComponent textComponent = new TextComponent();
        textComponent.setColor(net.md_5.bungee.api.ChatColor.DARK_AQUA);
        textComponent.setBold(true);
        textComponent.setText("+" + amount + " ("+ xp + "/" + (xp * 100) + ")");
        Bukkit.getPlayer(uuid).spigot().sendMessage(ChatMessageType.ACTION_BAR, textComponent);

        if(xp > level * 100){
            xp -= level * 100;
            level++;
            Bukkit.getPlayer(uuid).sendTitle(
                    ChatColor.AQUA.toString() + ChatColor.BOLD + "LEVEL UP!",
                    ChatColor.DARK_AQUA.toString() + (level-1) + " ➡ " + level,
                    4, 35, 7);
        }
    }```

[quaint mantle]

why did stand.setCustomNameVisible(true); work but not stand.setVisible(false);

[young knoll]

You can't use legacy string colors in components

[grim hound]

I send a buffer with a message

[spare hazel]

so what should i do

[echo basalt]

No clue, just keep in mind there are 2 packets for setting an entity "invisible"

[quaint mantle]

thing is

[echo basalt]

There's a visible field in the metadata and there's the remove packet

CustomNameVisible is also part of the metadata

But not part of the bitmask 0

[quaint mantle]

i had stand.setVisible(false); b4 too but it didnt work...this time i had both packet and .setVisible soo idek which one did it

i will removing .setVisible in next compile

[echo basalt]

I need more context

[spare hazel]

is this code correct

[echo basalt]

no

[spare hazel]

wait imma trry something else

[echo basalt]

homie you can't use legacy color codes like that

[quaint mantle]

i will do some debugging and if i still occur some issues i will lyk

[spare hazel]

Bukkit.getPlayer(uuid).spigot().sendMessage(ChatMessageType.ACTION_BAR, new ComponentBuilder(textComponent).create());

[echo basalt]

nvm that looks right

just

?tryandsee

[undone axle]

https://tryitands.ee/

[spare hazel]

alright

[spare hazel]

should i keep this in?

[worldly ingot]

No it does nothing

[spare hazel]

or should i remove the componentbuilder part

alr

[grim hound]

choco

do you know netty

or rather client-side decoding?

of bytebufs into packets

[young knoll]

I've manually made some packets via bytebuff and sent them to the client

[grim hound]

ohoho

[young knoll]

Pretty easy as long as you follow the format Mojang uses

[grim hound]

tell me

[quaint mantle]

after some debugging it was indeed the packet that did the magic!

[grim hound]

did you read the messages I sent?

czu I also do it

and it just

[grim hound]

does this

[young knoll]

Idk how the header would be messed up

[spare hazel]

so you sent packets wiithout using nms?

[young knoll]

afaik the game handles that

[grim hound]

what bytebuf did you use?

[young knoll]

Just a normal FriendlyByteBuf wrapping Unpooled.buffer

[grim hound]

why the wrap?

maybe I should wrap mine as well

and did you have some constant packets?

[young knoll]

Well you need to pass something to FriendByteBuf constructor

[grim hound]

I do it like that

[young knoll]

And it has a bunch of nice write methods

[quaint mantle]

        stand.setCustomName("something");
        SynchedEntityData data  = stand.getHandle().getEntityData();
        data.set(new EntityDataAccessor<Byte>(0, EntityDataSerializers.BYTE), (byte) 0x20);
        ClientboundSetEntityDataPacket dataPacket = new ClientboundSetEntityDataPacket(id, data.packDirty());
```can the name part be working cause i got the data after i set the name?

[grim hound]

I don't see it

FriendlyByteBuf

not a class

[remote swallow]

mojank class

https://mappings.cephx.dev/1.20.4/net/minecraft/network/FriendlyByteBuf.html

[grim hound]

oh it's PacketDataSerializer

[hushed scaffold]

yall know how if a player dies after getting hit by another player , for example a player a hits player b , and then player b dies from example fall damage , and it says that player b died while trying to escape player a ? is it possible to get who got kill credit or do i have to reimplement that myself

[young knoll]

getKiller in the death event

[hushed scaffold]

wouldnt that only get if the kill was direct ? like killing them with a melee weapon?

or does it get even if they died from natural causes after a player hits them

[young knoll]

No

It gets whoever would get the kill credit

(Or null)

[hushed scaffold]

oooh ty

[quaint mantle]

does someone know?

[echo basalt]

Try and see but that should work

[quaint mantle]

alr i will add the name setter after i send the packet

[echo basalt]

meh

[young knoll]

I hate that a bunch of the synced data fields for entities are private

[quaint mantle]

yea my theory was correct

since i set the name before it set the name

wait so i can just do the normal methods ands send a data packet at the end

good to know

[alpine urchin]

that’s your interpretation but it’s logical

nms would be analogous

the more you tamper around with NMS, the less help you can expect from the Bukkit community

since you’re doing some additional netty stuff, it’s not really my responsibility to help you use those features

[grim hound]

I'm aware

[alpine urchin]

i also mentioned its fair for you to use those netty things as an addition to my library

[grim hound]

but it's not like you help out of responsibility

[alpine urchin]

good

but saying im against you not fully using my api is reaching too far

since i mentioned i understand why you’re doing it

[grim hound]

public static ChannelFuture writeAndFlushConst(ChannelHandlerContext context, ByteBuf constByteBuf) {
        ByteBuf send = context.alloc().buffer().writeBytes(constByteBuf);
        return context.writeAndFlush(send);
    }
``` I changed it to this like ViaVersion does it

still doesn't help

[alpine urchin]

i might look at this again

[grim hound]

if you would allow constant wrappers

and also cache the silent context

then I'd really appreciate it

[alpine urchin]

make a github issue

[grim hound]

I'm so close

like I remade my whole plugin

and all of this stuff

[alpine urchin]

focus on ur plugin

and not this specific feature

lol

[grim hound]

and maybe even one line could've helped

to solve this

[grim hound]

well I'm currently

rewriting the core mechanics

or rather I already finished it

it's just that it kicks me out

[alpine urchin]

you can make an issue, and leave it in our hands

i’m generally not against it

once all other things have been solved, im down to add this little addition

[grim hound]

well it's pretty necessary for me

and also create like PacketCreationUtil

so that you don't have to create a new packet for each version by yourself

so methods like newPlayerInfo or newMessage and stuff

[alpine urchin]

nah

you have no idea of the work it takes to maintain this bad boy already

[elder wren]

Hello,

I'm looking to serialize the contents of players' inventories using a HashMap<UUID, ItemStack[]>.

I manage to store this via JSON in the following way:
{"568d365a-5fb2-4169-8e64-fb33b8c108ef":[{"type":"STONE","amount":1,"meta":{"repairCost":0,"hideFlag":0,"unbreakable":false,"damage":0,"unhandledTags":{},"persistentDataContainer":{"customDataTags":{},"registry":{"CREATE_ADAPTER":{},"adapters":{}},"adapterContext":{"registry":{"CREATE_ADAPTER":{},"adapters":{}}}},"version":2975}},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1},{"type":"AIR","amount":1}]}

It seems that you're having trouble loading the data back into a HashMap; it always ends up being null.

public static File onStaffModeFile;

@Override
public void onEnable() {

    try {

        getDataFolder().mkdir();
        onStaffModeFile = new File(getDataFolder(), "staffmode.json");
        if(!onStaffModeFile.exists()) {
            onStaffModeFile.createNewFile();
        }

        Gson gson = new Gson();
        Writer writer = new FileWriter(onStaffModeFile, false);
        BufferedReader reader = new BufferedReader(new FileReader(onStaffModeFile));

        HashMap<UUID, ItemStack[]> map = gson.fromJson(reader, HashMap.class);

        if(map!=null) {
            StaffCommand.setInStaffMode(map);
            reader.close();
        } else {
            gson.toJson(new HashMap<UUID, ItemStack[]>(), writer);
            StaffCommand.setInStaffMode(new HashMap<>());
            writer.flush();
            writer.close();
        }

[lilac dagger]

paste bin?

[rapid vigil]

?paste

[chrome beacon]

Is there a reason why you're using gson instead of the yaml config api?

[rapid vigil]

or

[lilac dagger]

gson doesn't serialize it properly

[chrome beacon]

^^ you'll need to fix your serializers

[tawdry echo]

someone have idea why dont work?

?notworking

[undone axle]

"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.

[tawdry echo]

everything already i send

thers no errors

[chrome beacon]

No you did not send what the run method is for example

[tawdry echo]

but last dont print

[chrome beacon]

what you expect it to do, and what actually happens

[tawdry echo]

void run(String sql, ThrowingConsumer<PreparedStatement, SQLException> consumer) {
        try (Connection connection = this.database.getDataSource().getConnection(); PreparedStatement statement = connection.prepareStatement(sql)) {
            consumer.accept(statement);
        } catch (SQLException e) {
            throw new RuntimeException(e);
        }
    }

last check dont log

statement#execute block but why

[chrome beacon]

Where's the throwing consumer from

[wet breach]

arena needs to be static since you are technically creating an inner anonymous class

[chrome beacon]

My guess would be that it's throwing an error

and that consumer is catching it

[wet breach]

most likely, but its also likely the error is that arena is not static lol

I don't see any other possible error it could be unless its some weird NPE

[grim hound]

bruh

oh wait

I was supposed to make an issue

[alpine urchin]

i said issue

wtf
