[sterile flicker]

can I set the texture for a snowball in 1.12.2?

I can't use a method with durability since they don't have it.

[chrome beacon]

No

You'll have to change all snowballs

or implement your own item the spawns a projectile

[sterile flicker]

well, except for the snowball, there is no entity/item/object in 1.12.2 that has a custom texture and can be thrown?

[worldly ingot]

Eyes of ender maybe :p That's probably it

[chrome beacon]

Listen for right click and spawn a snowball

[sterile flicker]

already

[chrome beacon]

change the itemstack it contains to your item with a different model

[sterile flicker]

there is no .setItem method

in 1.12.2

[chrome beacon]

Try nms

[sterile flicker]

Do you know a specific method?

[worldly ingot]

It's probably obfuscated so, unsure

There's a method somewhere in EntitySnowball that will accept an NMS ItemStack

EntitySnowball nmsSnowball = ((CraftSnowball) bukkitSnowball).getHandle();
nmsSnowball.setItem(CraftItemStack.asNMSCopy(new ItemStack(Material.DIAMOND_SWORD)));

It won't be setItem() though. It'll be some obfuscated method name

I see b(ItemStack) in some old patches, so start there I suppose

Or it might even be mapped to setItem() already

[sterile flicker]

.a(itemStack, int f)

[sterile flicker]

Can you say what the f means?

[worldly ingot]

Should just accept an ItemStack, no boolean

If you open the source for EntityProjectileThrowable you'll probably find the method you're looking for

Unless that didn't exist in 1.12. idk. We're talking about like 5 y/o software

7 years old even!

[slender elbow]

older than some of the spigot staff .....

[worldly ingot]

bro

facts

[slender elbow]

older than all of the paper staff, that's for sure

[sterile flicker]

there is no EntityProjectileThrowable class

only EntityProjectile

in 1.12.2

Hi, how can I query as an event when several signs have been placed next to each other and then drop? BlockBreak event is only triggered for the first sign

why the scoreboard is not visible at the second time you have do the update?

[echo basalt]

Static list and methods -> dedicated class

This is static abuse

Hard player references are memory leak prone and will cause problems in your current impl ;)

[lost matrix]

I think the physics event is fired for subsequently destroyed blocks

[lost matrix]

Hey there, i would highly recommend using a Map for this. A List is not suitable for this use case.
And your List (or preferably Map) should be in its own singleton class. Call it PlayerScoreboardManager or similar.

[lean pumice]

ok

[minor junco]

I would add: if you want to keep a Player to PlayerScoreboard relationship, you could use a WeakMap whose keys are weakly referenced, ensuring your Player and PlayerScoreboard objects are freed correctly

[lament hill]

Does anyone know about ormlite and if this would work? I've set the type to SERIALIZABLE

    @DatabaseField(columnName = "item", dataType = com.j256.ormlite.field.DataType.SERIALIZABLE)
    private ItemStack item;

[minor junco]

ItemStack is not implementing the Serializable interface, it does implement ConfigurationSerializable which differs entirely. So I don't think this would work as expected.

[lament hill]

ggs, ill make a work around, thank you for the quick answer

[vast wigeon]

I just opened intellij and got a error i have not had before with this.getServer().getPluginManager().registerEvents(new Events(this), this); when in Events i have ``` private static PalassetCustom plugin;

public Events(PalassetCustom plugin) {
    this.plugin = plugin;
}```

It says Cannot access caneless.com.PalassetCustom

[lost matrix]

Firstly, make your plugin field non-static

[timid hedge]

Does someone know why it says that it have may read the config wrong?

    public void onEnable() {
        plugin = this;
        getCommand("kit").setExecutor(new KitCommand());
        config.options().copyDefaults(true);
        saveConfig();
    }

[sterile flicker]

what is ItemSnowball.class for?

[lost matrix]

Where do you initialize config?

[timid hedge]

FileConfiguration config = getConfig();

[sterile flicker]

I am trying to set the texture of a thrown snowball or replace it with another object on 1.12.2

[lost matrix]

Thats only a declaration, not an initialization

[lost matrix]

Doesnt exist

[timid hedge]

I dont then, this is all i have with the config, the rest is just getConfig....

[sterile flicker]

it exists in the api for 1.12.2

[lost matrix]

If you never initialize a field, then its always gonna be null.
Calling a method on null will throw a NullpointerException

[sterile flicker]

ItemSnowball snowball = new ItemSnowball();
                snowball.b(CraftItemStack.asNMSCopy(new ItemStack(Material.SNOW_BALL, 1, (short) 1)));
                
                EntitySnowball nmsSnowball = ((CraftSnowball) p.launchProjectile(Snowball.class)).getHandle();
                nmsSnowball.shooter = ((CraftPlayer) p).getHandle();
                nmsSnowball.setLocation(p.getEyeLocation().getX(), p.getEyeLocation().getY(), p.getEyeLocation().getZ(), 0.0F, 0.0F);;

                nmsSnowball.getBukkitEntity().setVelocity(p.getLocation().getDirection().multiply(1));
                p.getWorld().spawnParticle(Particle.PORTAL, p.getLocation(), 20);

                p.addPotionEffect(new PotionEffect(PotionEffectType.SLOW, 5, 255));``` my code is more like random guessing to implement a snowball throw with a texture or a snowball throw with another object displayed

[timid hedge]

I dont understand how i do initialize the config

[lost matrix]

You can only add potion effects to LivingEntities.
Changing a snowballs item was only introduced in later versions of the game.

[remote swallow]

so your using config and getConfig

why

once again its time to learn java

[sterile flicker]

as for the texture? right now I'm using durability, which won't work like that. The snowball has no durability.

so this feature from 1.9 is useless

[lost matrix]

Changing a snowball projectiles item was added in 1.14

[sterile flicker]

is it possible to set a texture?

[lost matrix]

Sure. In 1.14+

[worthy yarrow]

I love saying the same thing 3 times over

[sterile flicker]

Why? what prevents from setting the texture

[worthy yarrow]

The fact it’s not an api method pre 1.14 probably

[sterile flicker]

This is not a projectile change.

[lost matrix]

The capabilities of both the client and the server

[worthy yarrow]

So then just go make a mod pack kek

[umbral ridge]

can you manually play a goat horn sound? xD

eg.: on player join

[lost matrix]

You could try a workaround, make the projectile invisible (not through potion effects) and mount it with an item that has a custom damage model.

[lost matrix]

Sure

Just search for playSound in the javadocs

[sterile flicker]

can I use packets?

[lost matrix]

To achieve what?

[kindred sentinel]

How to get if item was burnt by lava? EntityCombustEvent doesn't work

[sterile flicker]

in order to replace the snowball display with another item, maybe this was added to the api in 1.14.+ but there is a way to do this through packets

[worthy yarrow]

I don’t remember if there’s a player drop item event of sorts, if there is you’d probably have to get the item as it’s dropped and figure a way to make it not burn. But that’s just if you want to get the item and make it not disappear ig, there’s more you could do with it before it burns.

If it can’t burn, then you do whatever it is you wanted to do and then manually remove the item I suppose

[kindred sentinel]

oh, it's too difficult... To follow every dropped item, and wait until it burn/despawn/fall down

[lost matrix]

Ok let me explain again:

The minecraft client, has no way of handling or displaying a snowball with a different texture in those old versions.
You can send him all the infos you want, but the client will simply not understand it.

[sterile flicker]

ok. I understood

[umbral ridge]

So I need an entity to play it, Is it possible to play it for everyone on the server within the same world (spawn)? and have a fade out effect based on thier location like how its done with the note block, cd player? xD

[worthy yarrow]

No it’s rather just detection (the event/listener) and doing what you want before the item is burned, this all happens in your code as soon as the item is dropped meaning it won’t burn until your process is finished, or if you make the item unburnable

[lost matrix]

You dont need one

[sterile flicker]

but what do you mean by "mount it"

[worthy yarrow]

Can’t you like broadcast sounds to all online players?

[lost matrix]

You can add a passenger to entities

[worthy yarrow]

Really easily too?

[vast wigeon]

I've always used it as static

[umbral ridge]

Yeah but "This function will fail silently if Entity or Sound are null."

[lost matrix]

Cool. Now dont.

[lost matrix]

Search for other methods

[worthy yarrow]

The entity only needs to be the players currently online no?

[lost matrix]

No entity needed

[worthy yarrow]

Entity as in the one hearing the sound ie: player

[umbral ridge]

that's it then

will that have a fade out effect? xD

or will it be the same volume no matter where you are

[worthy yarrow]

Same I think with that method

You’re playing the sound to the world

I think…

The location Param probably refers to a player location I’d assume

[sterile flicker]

i already have code for this java EntityItem item = new EntityItem( ((CraftWorld) e.getWorld()).getHandle(), e.getLocation().getX(), e.getLocation().getY(), e.getLocation().getZ(), CraftItemStack.asNMSCopy(new org.bukkit.inventory.ItemStack(Material.SEA_LANTERN))); item.setNoGravity(true); for (Player player : Bukkit.getOnlinePlayers()) { ((CraftPlayer) player).getHandle().playerConnection.sendPacket(new PacketPlayOutSpawnEntity(item, 2)); ((CraftPlayer) player).getHandle().playerConnection.sendPacket(new PacketPlayOutEntityMetadata(item.getId(), item.getDataWatcher(), true)); ((CraftPlayer) player).getHandle().playerConnection.sendPacket(new PacketPlayOutEntityVelocity(item)); } item.startRiding(entity);

[worthy yarrow]

So perhaps run a for loop to get all online players locations

[sterile flicker]

Or is it something else?

[umbral ridge]

That kind of sucks xD

I could calculate the volume based on player distance from the location

that's one way

and for each entity play the sound with different volume

based on distance

[worthy yarrow]

Yeah but if you play sounds for each player location, I wonder for the players near each other would get a duplicated sound effect

[umbral ridge]

Yeah... so you DO NEED an entity at the end. I'll test it

[vast wigeon]

I made it private PalassetCustom plugin; and still get the message Cannot access caneless.com.PalassetCustom

[worthy yarrow]

Idk if smile says no, then there’s probably a reason. Ie: a workaround

[lost matrix]

Lets see both classes

?paste

[undone axle]

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

[worthy yarrow]

I’m not as versed in spigot / java as they are so perhaps just try a bunch of different processes and figure out a solid way to do what you’re trying to do

[sterile flicker]

7smile7 Is that what you mean by passengers?

[vast wigeon]

Main filehttps://sourceb.in/hUR8X4IvWP
Events filehttps://sourceb.in/6ylKrmeTRV

[lost matrix]

You are mixing real and virtual entities again. This wont work properly.

[worthy yarrow]

I think the universal practice for event listeners is one per class

[lost matrix]

You didnt import your class

[sterile flicker]

then how do I add a passenger for snowball

[vast wigeon]

What is that supposed to mean?

[sterile flicker]

#addPassenger instead of #startRiding?

[lost matrix]

You can take that literal. You did not import your class.

[vast wigeon]

Ahh, now i understand

But it shows up as it is impoprted

Cuz file of main is in caneless.com

[lost matrix]

If its packet based, send packets. If it actually exists, call the mount class

[vast wigeon]

And that is the same as pacakge

Would be easier if i could send images

[lost matrix]

Ah if they are in the same package then you might have a different problem.
What IDE are you using, and whats your package manager?

?img

[undone axle]

Can't send images? That's because you're not verified! Use !verify to complete verification.
Alternatively, you can upload screenshots to any image hosting site and share the link.

Here's some screenshot utilities that you can use to upload images.
Lightshot: https://prnt.sc

And its a maven project, right?

[vast wigeon]

Ye

[sterile flicker]

i found PacketPlayOutMount packet

[lost matrix]

Then invalidate caches and restart.
Click shift twice -> search for "invalidate ..."

[vast wigeon]

Double shift gave m,e this error https://sourceb.in/ibmirFpUgI

[lost matrix]

Try it out. Dont remember anything from 1.12 🤷

[lost matrix]

What

[vast wigeon]

https://imgur.com/a/qfyTlhX

[lost matrix]

What happens if you run mvn clean

Also: I think your IDE is completely broken and needs a clean reinstall.

[vast wigeon]

The code was fine yesterday

[lost matrix]

If it throws an exceptio when you press shortcuts

[vast wigeon]

I try to ide epair

repair

[worthy yarrow]

That's not a good look for the ide kek

[lost matrix]

I have literally never seen this problem. How did you nuke your ide like that?

[worthy yarrow]

You should feel good, you broke the best ide

[pallid oxide]

export settings and reinstall, usually fixes problems

[vast wigeon]

https://imgur.com/iQMBGTj

[umbral ridge]

I was wrong, there is Sound.Emitter, @lost matrix am I going in the right direction with this? xD Need to play a sound at a specific location and based on that location, players far away won't be able to hear it as loud as players that are closer to the emitter?

Sorry for tagging you smile

[worthy yarrow]

Location based sound basically?

With real world properties of how sound works? kek

[vast wigeon]

I didn't do anything

When i woke today my pc was off

And it worked 2 days ago

DIdn't use ide yesterday

[worthy yarrow]

To be fair for what you said you want it to do... I'd just play around with everything

It doesn't seem horribly complex

[lost matrix]

  public void playSomeSound(Location location) {
    World world = location.getWorld();
    Sound sound = Sound.ENTITY_GENERIC_EXPLODE;
    float volume = 1.25F; // How far away the sound can be heard
    float pitch = 1.0F; // How high or low the sound is
    world.playSound(location, sound, volume, pitch);
  }

Then "invalidate and restart"

[worthy yarrow]

Hey btw, volume in chunks?

[umbral ridge]

Ok thanks!

[vast wigeon]

Trying that

[umbral ridge]

will try it

[spring horizon]

If that doesn't work, send me a screenshot of the start of you main class.

[vast wigeon]

That fixed it

[spring horizon]

Np!

[worthy yarrow]

lmk on the volume measurements, I actually never figured...

[spring horizon]

IntelliJ cache sometimes (everytime) breaks everything.

[worthy yarrow]

@lost matrix I'm getting lost in this minigame project D:

[lost matrix]

Jep, minigames are hard to get right

[worthy yarrow]

Absolutely D;

I'm still working on the sumo mingame too

I'm not sure how I want to handle arenas

[spring horizon]

Tell me what are you struggling with

[worthy yarrow]

Figuring out what I need to do now haha

[spring horizon]

I have a little bit of experience with minigames (made 10 minigames in 3 months)

[spring horizon]

What have you done?

[worthy yarrow]

sec let me gather

Alright this is the foundation. The sumo minigame class is probably only about 20-25% done I'd say? The logic for the actual "sumo" battle is only decided by a 50/50 math.random right now haha

I've been quite busy the past couple days with birthday and what not so I haven't been able to work as much on it... now coming back to it after like 3 days has me quite lost

[umbral ridge]

works xD

[worthy yarrow]

That's an ugly ass sound sir

[umbral ridge]

XD

its a meme

[worthy yarrow]

Gotcha haha

[umbral ridge]

I should make it an earrape sound

volume to max

[worthy yarrow]

Dear god

It's a fugly sound, amplify to the max ofc

[grim hound]

yo

anybody here ever coded with anyone in intelliJ?

live the same project at the same time

live session

[lost matrix]

Sure, CodeWithMe is decent.

[grim hound]

doesn't it require some kind of license?

[worthy yarrow]

Yea

[grim hound]

so is it paid?

[echo basalt]

codewithme is icky

[lost matrix]

I think its in the ultimate version. If you are a student then you get it for free.

[echo basalt]

no plugins no nun

[worthy yarrow]

If you've got intelliJ then I think it comes with it no?

[echo basalt]

It works and it's surprising that it does but it doesn't work well

[grim hound]

I downloaded intellij when it was for free

[worthy yarrow]

Hmm

[grim hound]

so no license

I downloaded CodeTogether

but my friend can only edit on a web browser

[worthy yarrow]

ew

[grim hound]

ye

[lost matrix]

That one on the other hand is quite buggy

[grim hound]

well are there any alternatives?

[worthy yarrow]

What do you use?

(if anything)

[chrome beacon]

You can always just connect with Parsec

[grim hound]

what's that?

[chrome beacon]

not Intellij specific but it should work

[echo basalt]

git

[daring maple]

is there a real need for you to be coding concurently?

[worthy yarrow]

@spring horizon any thoughts? Or have you dismissed it haha

[daring maple]

what benefits would you get that you would not get while sharing screen during pair programming

[worthy yarrow]

2 people working on the same project means more can get done

[spring horizon]

LMAOOOOO

@worthy yarrow when working with stuff like that

always use teams

doesn't matter if it's 1v1

do a team

[daring maple]

in reality I don't really think this will be the case, unless two people can perfectly work together with minimal communication where as I wouldnt see the need of pair programming anyways

[spring horizon]

in case you want to change it to 2v2, you just have to create a team of two.

it's easier to maintain.

[lost matrix]

Sometimes its a case of:
If one violin can play a piece in 3 minutes, then 3 violins surely will be able to play it in 1 minute.

[spring horizon]

^

Depends on the tasks to be done.

[daring maple]

Ideally you'd have separation of concerns and no one has to work concurrently on the same part of the plugin

[worthy yarrow]

Hmm I got suggested that, I just don't understand why "sumo" normalized as a 1v1 game, would ever need to be expanded. But you're right for other minigames, I could instead use teams for the rest of minigame impl. So basically just convert to a teams system and just modify matchups based on the minigame yeah?

[daring maple]

in which case you could just use git and branches

[worthy yarrow]

Whatever way you do it, I don't think it matters as long as all of the party is contributing?

[spring horizon]

Don't do this, or every time you'll obtain this, it'll recreate the arraylist:

    public List<Event> getActiveEvents(MinigameType minigameType) {
        return minigameEvents.getOrDefault(minigameType, new ArrayList<>());
    }

Instead, do this, this will add the created list to the map if it doesn't exist.

    public List<Event> getActiveEvents(MinigameType minigameType) {
        return minigameEvents.computeIfAbsent(minigameType, ignored -> new ArrayList<>());
    }

[spring horizon]

Yup!

It's easier to maintain.

[echo basalt]

hm I wonder how well multi block change packets scale

[spring horizon]

If you cache it and use to all players, it'd be good.

If you create the packet per player, depends on how many blocks are you editing.

What do you want to do?

[echo basalt]

I've played with this before

Just like

farming stuff

estimating ~100 ish blocks per chunk

[grim hound]

uh

[worthy yarrow]

Ah that's a good catch, thank you!

[spring horizon]

lmao, yea

it'd work fine

[echo basalt]

I guess

[spring horizon]

np!

[sterile flicker]

is it possible to make the passenger follow the snowball?

[grim hound]

how can I share a github project with someone?

[worthy yarrow]

How should I go about the teams system? Probably some util used by all minigames?

[spring horizon]

wdym?

[echo basalt]

The way I currently do teams in my minigames is that each minigame has its own team impl

Which is created from a team template defined in the map data (spawn positions etc)

[worthy yarrow]

Ah ok

[spring horizon]

Yea, that's how it should be done.

[worthy yarrow]

Well that brings me to the next concern, I'm not too sure on how to handle the arenas... creation, handling of the areas (for sumo such as getting knocked off the platform), spawn locations, etc

[echo basalt]

I'd honestly have started with that before writing the whole game

[worthy yarrow]

kek

This is my first time trying to develop a minigame haha so ig I'll learn the hard way

[echo basalt]

hm 256 crops per chunk

[spring horizon]

yea, it's not bad

[echo basalt]

thing is we have like

lots of chunks

[spring horizon]

but why packets?

[echo basalt]

per-player thing and swm is overengineering it

[spring horizon]

Oh!

[echo basalt]

guy wants per-player crops but players to be able to see each other

I already use swm for islands

[spring horizon]

I imagine that you are using ProtocolLib, right?

[worthy yarrow]

Best way to handle uneven amount of players, toss a random bye each round til only 2 players remain?

[daring maple]

wouldnt you just use a queue

[echo basalt]

maybe

I can do this with raw nms though

[daring maple]

and then always grab first 2 people

[spring horizon]

Yea

[echo basalt]

I've done full client-sided chunks but it was a while ago

[spring horizon]

But it's easier to use ProtocolLib for intercerpting the block place and remove.

[worthy yarrow]

It's a chat prompt minigame such as you get the prompt, join, wait til minimum players join / start timer runs out, then battle it out and try to win.

[daring maple]

probably lacking a bit of context, but how would a queue not work here in the case of uneven players?

[worthy yarrow]

I don't want a queue is the context lol

[echo basalt]

overengineer time

[spring horizon]

https://cdn.gato.rip/2024-03/doOhEOAKvj3C4bFkABV1YbR359N86Vwu4bdTB7Rn8rrBky2BqE.png

[daring maple]

why? isn't the datastructure made for these situations?

This is the current impl to pair players for matches

[echo basalt]

ew

[vast wigeon]

So in arguments of a command, is /gamemode c the c in this argument 1?

[daring maple]

yes

[worthy yarrow]

Hey I'm pretty sure you said it was a valid way of pairing players :P, that's not to say you didn't mention how much you don't like it however

[daring maple]

args[0] tho

[echo basalt]

mutable object icky

Make team objects

[worthy yarrow]

That's the plan

[vast wigeon]

args[0] would be the command right?

[daring maple]

no that would be the command label

the command itself is not an argument

[vast wigeon]

So the command is not the first thing in the array?

[worthy yarrow]

Would 2 lists of uuid's be fine?

[upper hazel]

how to shut down the system when the value taken from the section is empty and because of this the value is taken from the config with the default value from intelji resource (config.yml)

[vast wigeon]

So in /gamemode c the arg c would be 0?

[echo basalt]

Why 2 lists?

[worthy yarrow]

Now that you say that

just split the uuid's from one list

yeah

[upper hazel]

I don't like that this system ignores checks like section.isInt and get default value from intelju resurce

[echo basalt]

class SumoTeam {

Collection<UUID> players
Color color
Location spawnPoint
int capacity

}

type deal

[molten hearth]

All my homies use audiences

[worthy yarrow]

gotcha

[daring maple]

yeah

[spring horizon]

💀

[echo basalt]

class SumoTeams {

Collection<SumoTeam> teams
int getTotalCapacity() -> ...
void addPlayer(Player)
void removePlayer(Player)
boolean isPlayer(Player)

}

idk

somn like that

shitty code so you can't copypaste

[daring maple]

in the args array 'c' would have index 0

[echo basalt]

[lost matrix]

???

[molten hearth]

That was a trick message I in fact hate anything paper related you pass my vibe check

[worthy yarrow]

Thank you haha

[spring horizon]

[worthy yarrow]

I wasn't trying to lol, this is a learning project.

[sterile flicker]

Teleport entityitem to the snowball's position

[quaint mantle]

@echo basalt why do you use linked lists and linked hash maps over just the plain arraylist and hashmap

[sterile flicker]

I can't do it in any way

[echo basalt]

I don't

I abuse ConcurrentHashMap

:)

Isn't LinkedHashMap ordered?

[quaint mantle]

oh yeah it is

[echo basalt]

Well

[quaint mantle]

but I see you abuse linkedlist

[echo basalt]

By insertion order

[spring horizon]

i do that too LMAO

[echo basalt]

I don't?

I use it like 10% of the time

[quaint mantle]

oh what

[vast wigeon]

https://sourceb.in/LG3nlAXCw7 Then why whenever i do gamemode s nothing happens?

[quaint mantle]

Whenever I see your code I never see ArrayList

[upper hazel]

this only applies to sections with numbers

[echo basalt]

You never see list in the first place

I guess it's just the way I see the data

[quaint mantle]

Ok I'm buggin then

[lost matrix]

You dont need to do that.

[echo basalt]

I'd argue that obsessing over LinkedList vs ArrayList is in part premature optimization

[quaint mantle]

I can understand concurrent maps

Isn't that like thread safe

[lost matrix]

LinkedList is always worse, in any scenario.

*Except one very specific

[echo basalt]

make sure to create your array lists with an initial capacity of Integer.MAX_LIMIT to avoid resizing

[shadow night]

I love when my list allocates 2 billion bytes (or something, idk)

[sterile flicker]

and what can I do besides this to achieve the expected result?

[lost matrix]

Just mount the entity on your snowball

[sterile flicker]

But entityitem won't move together with a snowball

[lost matrix]

If you mount it, it will

[wintry lynx]

Its used once and Im the only one who will ever touch the code, plus, the code is only 12 lines long and this is at the top.:

Its not accessible via a method either so its never used.

[daring maple]

because the length of the array is not 0

the if(args.length==0) is false

[vast wigeon]

Then how i make it not false

Cuz i do /gamemode s

[daring maple]

well the argument array has length 1 because it has 1 argument

but that argument has index 0

[candid inlet]

ArrayList is almost better in all cases, I don't see why would you prefer LinkedList over ArrayList

[daring maple]

if you wanna know more you should look into Java OOP

[vast wigeon]

So i check if args.length is 1 and i do args[0] to get the gamemode then

[daring maple]

yeah

[kind hatch]

LinkedList is memory management type shit.

[vast wigeon]

Doesn't make sense, but thanks

[pseudo elm]

public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        if cmd.getLabel() == "Testcommand" {

        }``` is it getlabel getname or what is it to check which command was executed

[kind hatch]

#getName() returns the name of the command.
#getLabel() returns the alias of the command that resolves to #getName()

[pseudo elm]

ok thx

[vast wigeon]

What would i do in this situation then? if(args.length == 1) { if(args[0] == "gi" || args[0] == "give") {

Is it args[1] ==

[daring maple]

if that would be something like /eco 'player' give

then give would be args[1]

[vast wigeon]

It /eco give 'player' 'amount'

[daring maple]

then give is argument 0

[pseudo elm]

Player player = (Player) sender;```
why is the player inbetween ()?

[kind hatch]

Casting

[vast wigeon]

I will send my whole code for it, cuz right now it does nothing https://sourceb.in/m5XCqGTUQa

[kind hatch]

CommandSender != Player
However it can be converted to one by casting.

[daring maple]

so you would then have something like

if(args.length==3) {
  string command = args[0];
  string playerName = args[1];
  string amount = args[2];

  // do something based on these variables
}

[glad prawn]

but CommandSender could be Player, so

[daring maple]

keep in mind that you mind not get a player returned in Bukkit#getPlayer() if the name is wrong

[glad prawn]

I think you have to mention that if he understands what he's doing

[vast wigeon]

I know, but should i use .equals instead of ==?

                    LootContext lootContext = builder.build();
                    player.sendMessage("lootContext : " + lootContext);

                    Inventory lootInventory = Bukkit.createInventory(player, 27, "Loot chest");
                    player.sendMessage("lootInventory : " + lootInventory);
                    
                    try {

                    }

The error : Missing parameters
I assume it comes from the lootcontext
Is anyone have an idea ? i ve worked for hours on it ...

[umbral ridge]

Is PDC per block? What if I have a chest with size 2 blocks? is PDC transferred via Chest or Block? I guess it's a Chest?

[young knoll]

It's connected to the tile entity

Hello ! Do you know why when i break a chest that call an inventoryCloseEvent ?

if needed thats my code

        event.getInventory().getLocation().getBlock() ==null && 
        ((Directional) event.getInventory().getLocation().getBlock().getBlockData()).getFacing() == null)return;

    signBlock.setType(Material.OAK_WALL_SIGN);
    Directional directionalData = (Directional) signBlock.getBlockData();
    directionalData.setFacing(chestFacing);
    signBlock.setBlockData(directionalData);
    signBlock.getState().update();

    Sign sign = (Sign) signBlock.getState();

Error

[worthy yarrow]

craftblockdata cant be cast to directional

[cursive loom]

Yes I see this bur why it's happen when I break a chest

the event is InventoryCloseEvent not BreakBlocksEvent

[worldly ingot]

It would only ever call an InventoryCloseEvent if someone had the chest inventory open while the block was broken

[cursive loom]

I'm alone on the server

[worthy yarrow]

?paste show more code

[undone axle]

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

[worldly ingot]

Yeah, something is calling that method for some reason

[cursive loom]

You want to see more of my code ?

[worldly ingot]

Yes

And if you have a BlockBreakEvent anywhere, that would be relevant as well

[worthy yarrow]

just paste the whole class

[worldly ingot]

Actually BBE isn't relevant, stacktrace says it's a close inventory event lol

[lost matrix]

Pls allocate more variables at the beginning, like the Inventory, Location and Block.
And use guard clauses:

if(!condition) {
  return;
}

It makes your code way cleaner

[rough ibex]

if (!cond) return; imo is hotter

[lost matrix]

imo its not 🙂

[rough ibex]

fair enough

[lost matrix]

But im ok with calling that a preference

[cursive loom]

what is the condition ?

[rough ibex]

any condition necessary

[lost matrix]

Whatever you want it to be

[cursive loom]

exemple ? plz

[worthy yarrow]

Ig it depends on how you want to handle those cases

[rough ibex]

instead of doing ```java
if (cond) {
// a bunch of stuff
// many lines
// like a lot of lines
}

```java
if (!cond) return;
// a bunch of stuff
// not indented anymore (we don't need to)```

[tardy delta]

if (!cond)
{
return;
}```

[cursive loom]

yes x) but what is condition

[tardy delta]

ha ! had smile stop typing for a moment

[rough ibex]

any condition

its up to you

to use the guard clause as a tool

[worthy yarrow]

Instead of checking to see IF something... check to see IF it's not something

[lost matrix]

Inventory inventory = event.getInventory();
Location location = inventory.getLocation();
Block block = location.getBlock();

if(block == null) {
  return;
}

BlockData blockData = block.getBlockData();

if(!(blockdata instanceof Directional)) {
  return;
}

Directional directionalData = (Directional) blockData;

... and so on

[worthy yarrow]

If it's not what you want, then its a guard tool

[cursive loom]

ahhhhhhhh ok, I don't thinking about this ! thx you

[worthy yarrow]

if it's what you want then just add the guards to ensure it does what you want

The main spigot-1.18.jar is now a bootstrap jar which contains all libraries. You cannot directly depend on this jar. You should depend on Spigot/Spigot-API/target/spigot-api-1.18-R0.1-SNAPSHOT-shaded.jar, or the entire contents of the bundler directory from your server, or use a dependency manager such as Maven or Gradle to handle this automatically.

i have an itemstack and its a potion

and i want to change its level

[chrome beacon]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/inventory/meta/PotionMeta.html

Get the effect and then increment the level and set it back

[spare prism]

tried to find here

[umbral ridge]

hey

[spare prism]

dont see any methods to do that

[rough ibex]

hi

[spare prism]

to set a level

only to change potion effect type

[chrome beacon]

Yeah that's what you want to do

[spare prism]

but it doesnt change the level

only the type of the potion

[chrome beacon]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/inventory/meta/PotionMeta.html#addCustomEffect(org.bukkit.potion.PotionEffect,boolean)

Add the new effect

[spare prism]

yeah but then i have to remove the base effect

and i only see a method to remove custom effects

[chrome beacon]

Why do you need to remove the base effect

[spare prism]

cause i dont want to duplicate the effects

i want only one potion effect

When many chunks are loaded, memory easily becomes full. I only let it restart until the end of the day

[chrome beacon]

?

[lost matrix]

But if the world is only reset on restarts, then there is no way of a memory leak developing.
And simply setting the world to be non-persistent doesnt create a memory leak on its own.

[flint coyote]

Does setting a world to non-persistent prevent chunk unloading?
Or does it simply reset the chunk once unloaded?

[chrome beacon]

Chunks reset

I believe

[flint coyote]

Yeah if that's the case there won't be a memory leak

But I never tested that

do PersistentDataHolders save data over a server restart

Yes

That's why they are called "Persistent"

[sand spire]

Hey, should I store inventories as an encoded string, byte array or something else?

in a database

[slender elbow]

sql has a blob type

use that

[sand spire]

I'm using MongoDB rn is any of these blob?

[chrome ferry]

Well personally I assume array and then serialise all items in the inventory to a byte[]

[lost matrix]

For MongoDB you shouldnt manually serialize objects. Make sure your codec can serialize your data and then simply use a MongoCollection<YourObject>.
That being said: You can just use a String if you must.

[chrome ferry]

That is smart

[sand spire]

What is "my codec" in this situation, is it built in my IDE or MongoDB, And the datatype inside the MongoCollection can only be a datatype I can normally use too right? Or can I somehow save stuff like a file or like these weird characters

[lost matrix]

codec is short for "encoder and decoder". You can store anything into MongoDB as long as your codec knows how to serialize it.
You could for example create a custom PlayerData class and store it directly in a MongoCollection<PlayerData> with the UUID being your document ID.

How are you serializing your ItemStack?

[sand spire]

Right now I'm doing it like this in the players PDC

ByteArrayOutputStream io = new ByteArrayOutputStream();
                BukkitObjectOutputStream os = new BukkitObjectOutputStream(io);

                for (Map.Entry<Integer, ItemStack> entry : items.entrySet()) {
                    os.writeInt(entry.getKey());
                    os.writeObject(entry.getValue());
                }
                os.flush();
                byte[] rawData = io.toByteArray();
                String encodedData = Base64.getEncoder().encodeToString(rawData);
                data.set(new NamespacedKey(CustomItems.getINSTANCE(), "PlayerVault" + number), PersistentDataType.STRING, encodedData);
                os.close();```

[lost matrix]

Alright then lets not make this too complicated. Simply store your "encodedData" in MondoDB as it is.

[sand spire]

Alright thank you 👍

Publishing shanged code on the other hand is not allowed.

[quaint mantle]

Hm

So what does build tools actually do

Does it decompile a jar

[remote swallow]

it downloads minecraft, decompiles it, patches it then builds bukkit, craftbukkit and spigot

[dry forum]

is it possible to make a slime sit inside of a block? like how armorstand.setMarker works?

[small holly]

quick question, I am having some issues with GSON and NMS honestly no idea why its trying to do this class but I will get to that when I do lol anyway I am getting this error Caused by: java.lang.IllegalArgumentException: Class net.minecraft.core.BlockPosition declares multiple JSON fields named 'a'; conflict is caused by fields net.minecraft.core.BlockPosition#a and net.minecraft.core.BaseBlockPosition#a

// gson builder
private static final Gson gson = new GsonBuilder()
        .disableHtmlEscaping()
        .setPrettyPrinting()
        .serializeNulls()
        .excludeFieldsWithModifiers(Modifier.VOLATILE)
        .create();

1.20.4 btw

ideally I wanna avoid adding Modifier.FINAL even though it will likely fix it

[small holly]

oml ik why its trying to serialize it... its trying to serialize the entire world

[umbral ridge]

https://tenor.com/view/no-way-angry-shake-head-not-happening-upset-gif-14656457

[small holly]

Ik the likely cause it doesn't Realllllyyyy support java 9+ from what I can find

[rough ibex]

gson should definitely work with java 9+

[lost matrix]

What are you trying to serialize?

[small holly]

Its a general issue now with gson in java 17 trying to serialize stuff that it cant I think I know what to do

but also I am changing what caused that issue

[small holly]

It was attempting to serialize org.bukkit.World when it really shouldn't

[lost matrix]

.excludeFieldsWithModifiers(Modifier.VOLATILE)

[lost matrix]

Are you trying to serialize a Location?

[small holly]

it was for an underlying issue that I am trying to fix

[small holly]

not it was like an entire world

I don't need that to be done lol

[lost matrix]

Ok but was that a transitive serialization or did you just throw a World at it and hoped for the best

[small holly]

Its something from a while ago that I forgot I still had

I used to have .excludeFieldsWithoutExposeAnnotation() so it was mostly ignored

but I am trying to not require that lol

[lost matrix]

If you dont want fields to be serialized, then simply use the transient keyword

private transient World world;

[small holly]

mhm

[lost matrix]

Alternatively you can just register a type adapter for worlds, which saves a UUID and deserializes it back to a World

[small holly]

Might actually do that tbh

[lost matrix]

Can cause problems when worlds arent loaded while deserializing

[small holly]

wanting to remove this because I am using gson to serialize classes for custom NBT data it was working with @Expose ofc but I wanted to add other stuff like ItemStack and stuff so I can't rely on @Expose

[lost matrix]

Btw a few days ago we came up with a pretty neat type adapter to serialize ConfigurationSerializable objects like ItemStacks, Locations, etc
#help-development message

[small holly]

actually gonna add that lol thanks for that

[lost matrix]

Just remember that you need to register the ItemStack one as a TypeHierarchyAdapter instead.

Because the CraftItemStack impl is cursed

[lilac dagger]

Does this adapter serialize the whole itemstack?

And not just what craft itemstack does with serialization?

[hybrid turret]

ic, thank you

I'm establishing a connection do my sqlite .db-file using DriverManager#getConnection. Is it better practice to use try-with-resources (to close the connection every time I'm done with my request) every time I want to access the DB or can I keep the connection instance stored in my Database-object?

[lilac dagger]

just keep it stored

if you ever made a connection for the first time on main thread you'll know how slow it is

[wet breach]

there is no connection for sqlite db's as they are files. That being said yes you should close the resource since it is a file if you are done with it.

[lilac dagger]

ah sqlite

[hybrid turret]

Okay thank you

Lil verbose but as long as it's good for performance

[lilac dagger]

it won't improve performance

just that you unlock the database

[wet breach]

^

[hybrid turret]

ahhh

i get it

i'm stupid lmao

[inner mulch]

does some1 know how i can setup "fallback values" in hibernate, so that a column has some default values as well as if there is an error gathering values it can return back to default?

[hybrid turret]

How much difference in performance do yaml/json files, sqlite-files and a mysql database server provide?

[wet breach]

mysql database server is just that, it is its own server and therefore its an entire application that takes care of a lot of stuff that is normally issues with flat files. Json, yaml, are flat file human readable files. Sqlite is a file but its binary storage since you can't just simply view that data by opening the file. MySQL if we compare all these is the most optimal and none of the rest will come close to it. Next is the Sqlite with its disadvantage being if its size becomes too large it starts to decrease in performance. Then you have Json/Yaml which also suffer the same thing as Sqlite but at smaller sizes then sqlite.

[hybrid turret]

I see so on a larger scale, sqlite has the same problems as flat files, did I get that right?

[wet breach]

should use Yaml files mainly for config files or small amount of data storage. Json itself isn't meant as a storage medium and its format is best use for transmitting data

[wet breach]

yes

[hybrid turret]

understandable

When trying to store items in a db (or rather ItemStack-Arrays, for storing an Inventory), would it make sense to store a singular item as a json string?

Bc i have no idea how else I would be storing and much less retrieving the data of an ItemStack

[wet breach]

if you are going to store a lot of data and also need that data everywhere else, best to go with MySQL or Mongo however I don't have any personal experience with mongo but I have heard and been told it is pretty good too depending on what you are doing or how you are using the data.

[wet breach]

You could serialize and store as a BLOB if you wanted

BLOB = Binary Large Object

[hybrid turret]

I want to try creating a QoL plugin for smaller and bigger servers. So: scalable for big servers but easily understandable and usable for smaller servers

[wet breach]

or you can serialize and store that serialization as a string

[hybrid turret]

Okay, I'll be reading up on that then

[hybrid turret]

yeah, that's what I intended. Bc rn I'm storing in inventories in json

Just an Array of json-objects (item) in a json file. And I want to migrate this into sqlite

or a database

[wet breach]

I personally store such things using base64

[hybrid turret]

quality of life

[wet breach]

so that I avoid storing weird characters

[hybrid turret]

how would that work?

[wet breach]

you just encode the serialization with base64

thats all

[hybrid turret]

that's the reason i'm using sqlite rn, I (at least rn) do not want to make small having to setup a mysql server

[wet breach]

and then you just ensure to decode it. Sometimes weird characters which you can occasionally get from serializing can cause issues if you are not expecting them, especially in java 😛

[hybrid turret]

So I would serialize to a string (and convert to a byte array) and then store a Base64-String?

[wet breach]

yep

but you don't need to go to string from serializing though

its serialize - > byte - > base64

then you have a string

[hybrid turret]

But the serializing will return a string first anyway

or am i misunderstanding? lol

[wet breach]

depends how you are serializing

there is more then one way to do it

[hybrid turret]

rn, gson

[wet breach]

then I guess if you want to deal with strings like that you could just encode the strings in your case

[hybrid turret]

what would the optimal way for doing this?

I'm a lil perfectionist lmao

And I feel like, optimazation-whise, my plugin is horrible, but I'm still studying, so ig that's fine

[dawn flower]

if i want to make an event system (player events only) that the player can listen for events ingame directly and execute 'activators', something like skript but ingame not a text-based language, do i have to make a listener for each player event possible and save all the changeable fields possible in a custom class, for example PlayerJoinEvent has join message that can be changed, or is there a better and more optimized way to do it?

it'd take like 2 hours just writing everything for like 13+ events and marking everything as cancelable or not cancelable and the changeable args and the immutable args

no like, i want to know if there's a way to tell the difference between fields that can be changed and fields that cant

using code

how?

alr

[wet breach]

shouldn't worry about this. You should make your plugin according to the design you have in mind. Then afterwards test and profile it

only profiling and testing will tell you what is or is not an issue

[hybrid turret]

huh, interesting

[hybrid turret]

yeah that makes sense

[wet breach]

if you are going to use the bytes, you need to use setBinaryStream

of preparedstatement

then you use a bytearrayinputstream

[hybrid turret]

Ahhhhhh

[wet breach]

and feed the bytes into that

[hybrid turret]

i'm gonna try that out rq

[wet breach]

the other method you could use is setBytes of preparedstatement

but I think the the binarystream is a bit better as its less prone to messing up

 pSstatement.setBinaryStream(2, new ByteArrayInputStream(bytes),bytes.length);

pSstatement.setBytes(2,bytes);

[hazy parrot]

just a note that setBinaryStream is not implemented in some drivers (SQLite for example)

[hybrid turret]

Okay interesting, so I just set setBytes or setBinaryStream and it writes a string (or varchar, whatever) to the db, cool

So I can skip the final String base64String = new String(base64Bytes, STandardCharsets.UTF_8);

cool

[hybrid turret]

tbh it seems to work for me, I'm using SQLite

[lilac dagger]

i like saving it as string

not sure which data type would require to save as bytes instead

it's easier for a human to read

some people might wanna search the database themselves

that's cool

definitely worth it

there isn't one

i have a bedwars_time table that tracks weekly monthly

last time since purge

i have no idea about h2

but this is how i did it

pretty much what i did

you can do a repeating task that repeats every day

make the first be at 0

so if he restarts it'll always trigger

task = Bukkit.getScheduler().runTaskTimer(getEngine().getPlugin(), () -> getDatabase().getPlayerData().checkPurge(), 0, 7200);

actually it's uhm 1 hour?

wait it's minutes wth

6 mins

i forgot a 0

[glossy sand]

Alright so.... It would seem after a whole bunch of investigation from me and a lot of other people, we seem to have found the issue of what https://hub.spigotmc.org/jira/plugins/servlet/mobile#issue/SPIGOT-7475
does - and potentially also a quick easy fix for it. Now whom can I bother with all the information pertaining to it who can hopefully also make a PR or something?

Perfect, can I take this into your dm's?

Yes

This is currently not fixed. I don't want to send in issues/discord threads from other discords here but it seems the issue has likely since been found

It just takes someone to implement the fix and quite frankly I don't know anything about anything in that regard.

Yes. But the plugin is not at fault, it's because of a spigot implementation.

https://hub.spigotmc.org/stash/projects/SPIGOT/repos/craftbukkit/browse/src/main/java/org/bukkit/craftbukkit/util/TransformerGeneratorAccess.java#58-78

i can either link to the thread where a bunch of people smarter than me are discussing it, or i can try to regurgitate the conclusions and hope i get them right

But as far as i understand, this would be a working fix to the issue

One second, i may have sent the wrong issur

https://hub.spigotmc.org/jira/plugins/servlet/mobile#issue/SPIGOT-7596

I can link you pretty much all the info necessary to reproduce, everything found in testing plus the details about how to likely fix it - i just don't think i am allowed to link to these things here

[glossy sand]

I'm just saying - this goes for anyone who'd be willing to look into it and make a pr with my info. (I really desperately need this fixed lol)

[quaint mantle]

i apologize if this is a stupid question, but is there a way i can cancel a BukkitRunnable task with an event?
i wanna cancel this task when the player dies
im new to the spigot api

[echo basalt]

you're new to java

[lilac dagger]

move task count field above run()

change runtasklater to runtaskEvery

or how it was named

it takes plugin, startafter, every

[inner mulch]

when using hibernate, imagine i have an enum save it with hibernate and later change something in the enum (might remove constants) how do i handle illegalargumentexceptions from hibernate (if it tries to find an enum that alr got deleted)?

[lilac dagger]

with bukkitrunnable you can just call cancel();

from within run();

@tidal cove

[inner mulch]

i think he left the server

[lilac dagger]

all the analysis for nought

[inner mulch]

yes

😔

[glossy sand]

if you're bored wink wink

[lilac dagger]

@inner mulch try to ask chatgpt, there's no way they didn't account for removal

i never used hibernate so i can't help

but it sounds like a basic feature

[inner mulch]

i asked chatgpt and he tells me to use a converter which consists of switch statements to convert everything to an enum to my liking

but switch statements arent so great to say the least

[lilac dagger]

hmm, maybe duck it

or google it

[inner mulch]

i alr googled and they said the same

thats where chatgpt got it from it seems

and personally this solution is not it, I'd rather have a fallback value that it changes to when its null or an exception is thrown

[lilac dagger]

try ordinal if needed

[inner mulch]

ORDINAL works, but it doesnt fallback to what i want it just fallsback to whatever get into place there

[inner mulch]

and if ordinal number is too high and i remove to many it breaks as well

[lilac dagger]

suprised hibernate doesn't have a proper way to handle this

[inner mulch]

they have to have a proper way

be4 using hibernate this could easily be fixed by catching illegalargumentexception and then setting the value to a default value

i cant believe they havent implemented this as its that easy

[lilac dagger]

maybe they have annotations for it like i did for myself

[inner mulch]

you created your own hibernate?

[lilac dagger]

i guess

[inner mulch]

nice bro, yeah i dont know how to process annotations

[lilac dagger]

the implementation is only for yml

since this is what i need it for

[quaint mantle]

Appreciate the help, thx

[lilac dagger]

it's not as hard as you think, just the tiniest amount of reflection is required

[lilac dagger]

yay, welcome back

[quaint mantle]

if i use PlayerSwapHandItemsEvent does event.getMainHandItem() return the item which player is trying to put in offhand?

also mainHandItem.getItemMeta().hasDisplayName() how can this give nullpointer exception?

if(mainHandItem != null && mainHandItem.hasItemMeta() && mainHandItem.getItemMeta().hasDisplayName() && mainHandItem.getItemMeta().getDisplayName().equals(itemName))

i mean does it look goofy?

[smoky anchor]

if meta is null, which happens for air item

[quaint mantle]

yea but i already checked if item is null or nah

[molten hearth]

does java have any logging libraries that dont look ugly

[quaint mantle]

or is air considered seperate item

[smoky anchor]

ItemStack(Material.AIR) is a thing, and that returns null meta

[quaint mantle]

ic

[smoky anchor]

make a var for the itemMeta, don't get it thrice, it creates a copy each time

[quaint mantle]

oh alr

if(mainHandItem != null && mainHandItem.getType() != Material.AIR && mainHandItem.hasItemMeta() && meta.hasDisplayName() && meta.getDisplayName().equals(itemName)){

does it look fine now?

can u drag air ?

[smoky anchor]

getType().isAir() would be better
and with that I don't think you'd need the hasItemMeta

[quaint mantle]

That makes sense, my goal is for the task to cancel when the player dies

[quaint mantle]

Yea, sorry I left in the beggining, my social awkwardness got to me 😅

[lilac dagger]

make sure you do all i said

it'll save you some headaches later on while debugging

[quaint mantle]

Alrighty

Thank you

[quaint mantle]

is there a config guide for spigot?

[quaint mantle]

Just for clarification
I should move the task count field above run
Rename runtasklater to runtaskevery
And only have cancel() within run()
??

[lilac dagger]

yes

[chrome beacon]

Do you want to make your own config?

[lilac dagger]

you can have cancel outside run too

[quaint mantle]

yes

i made my own config.yml in resource folder

[chrome beacon]

?configs

[undone axle]

See this wiki page on how to use custom configuration files: https://www.spigotmc.org/wiki/config-files/

[quaint mantle]

but i want to see its saving and stuff

alr thanks <3

so just adding this.saveDefaultConfig();

will work?

its onEnable method ig so it will work

[quaint mantle]

And all the logic for task count should be outside of run?

i have a small question

private final File dir = new File(WhosThatPixelmon.getInstance().getDataFolder().getAbsolutePath() + "//sprites"); is this correct way to go to sprites folder in my plugin foldor?

[drowsy helm]

Dont do private final

Assign it after onEnable

[chrome beacon]

new File(plugin.getDataFolder(), "sprites");

[lilac dagger]

no, just the field, it should be within the runnable that executes it otherwise it'll break when more than 1 player needs it

[quaint mantle]

thanks 👍

[sand spire]

Does a string or binary take less space?

[quaint mantle]

So I should move the task count field to be just above run()

[lilac dagger]

yeah

it's basically a different class when you put it above/along run()

[fallen lily]

They will be indifferent lol

[sand spire]

oh

thanks

[native nexus]

I am assuming you do not want the data to be readable

And you are storing it in a flat file

[sand spire]

I want it to be readable by my code

[sand spire]

i'm storing it in a document, in a collection, in a database using MongoDB

[native nexus]

I was about to suggest sqlite but nvm

And I have never seen someone put binary data into a database, maybe that’s just new to me 😅

[sand spire]

idk, I thought it might be more optimal than saving all the itemstacks with their properties readable

[inner mulch]

when using hibernate, imagine i have an enum save it with hibernate and later change something in the enum (might remove constants) how do i handle illegalargumentexceptions from hibernate (if it tries to find an enum that alr got deleted)?

[sand spire]

try {
    // Hibernate operation that may cause IllegalArgumentException
} catch (IllegalArgumentException e) {
    // Handle the exception, perhaps by logging an error or performing some fallback action
}```

[inner mulch]

thats not how hibernate works tho

[sand spire]

idk I asked chatgpt

[shell robin]

How can I check if a mob spawned from spawner or not?

[sand spire]

#getEntitySpawnReason()

[tidal marlin]

Hello !
I'm trying to display players' head in menus.
Here is my problem : when a player is offline, the displayed head is a default one, not the player's head.
Someone knows how to fix that ?

This is the code :

// baseItem : an ItemStack object, the meta of this item is an instance of SkullMeta
// id : the UUID of the player
// Set the player skin on the head
OfflinePlayer offlinePlayer = Bukkit.getOfflinePlayer(id);
SkullMeta meta = (SkullMeta) baseItem.getItemMeta();
if (offlinePlayer.getName() != null) {
  meta.setOwningPlayer(offlinePlayer);
  baseItem.setItemMeta(meta);
}

[chrome beacon]

remove the getName check?

[inner mulch]

is having 10 runnables splitting tasks less efficient than having one containing all the task of the 10? or is the notice in performance ignorable?

[chrome beacon]

I'd say it's negligable

Keeping the code clean and readable is more important

[tidal marlin]

He's not null, I've already checked

[chrome beacon]

So it does work when a player is online?

[tidal marlin]

Yeah

[chrome beacon]

Try using the getOfflinePlayer with the user name instead

That should do a web request lookup

If possible do that async

[tender shard]

or use getPlayerProfile(), then update() it

[tidal marlin]

I can't, don't have the plyer name here

[shell robin]

    @EventHandler
    public void onSpawnerSpawn(SpawnerSpawnEvent e){
        if(e.getEntity().getType() == EntityType.ZOMBIFIED_PIGLIN){
            if (Math.random() < 0.60) {
                e.getDrops().add(new ItemStack(Material.GOLD_BLOCK));
            }
        }
    }```I'm trying this but I couldn't use #getDrops() method in this event. How can I set items that the mob will drop?

[tidal marlin]

I've already tryed with PlayerProfile, but not with an update, I'll test that thx !

[shell robin]

Yeah

Players collect the items dropped by the mobs coming out of the spawner with a hopper

Therefore, I need to adjust the item it will drop when it dies

[tender shard]

note that update() returns a Future so you'll have to use whenComplete() or get() or join() (or whatever) it before getting the username

[shell robin]

    @EventHandler
    public void onEntityDeath(EntityDeathEvent e) {
        LivingEntity entity = e.getEntity();

        if (entity.getType() == EntityType.ZOMBIFIED_PIGLIN) {
            if (Math.random() < 0.60) {
                e.getDrops().add(new ItemStack(Material.GOLD_BLOCK));
            }
        }
    }```
I can do it like this but I don't know how can I check a zombified piglin spawned from a spawner in EntityDeathEvent

As I know yes

[chrome beacon]

Try what mfnalex mentioned

[shell robin]

But it is possible and if this is not a wrong choice, I think I can get what I want by using the getDrops() method

[tall dragon]

youuu could apply a tag on entities that are being spawned in CreatureSpawnEvent

which you could then check for when they die

[agile anvil]

What about if the server reboot?

Pdc is safer and easier

[tall dragon]

ok what if that entity despawns

thats just annoying

[shell robin]

What do you mean by tag? Should I give them a special name and check if the piglins with that name are dead?

[tall dragon]

Fair but it’s still safe if it’s not on the main thread and you use an executor service?

It is safe, no one said it isn't, but also bad practice, bad for performance and indicator of bad design in most cases
