Biome are registry backed as of 1.21.3 so yeah
Registry.BIOME
inner mulch
Arent value based hash implementations bad because once the objects values change, a hashmap doesnt point to its value anymore?
torn shuttle
Biome are registry backed as of 1.21.3 so yeah
no but I mean
can I check what name a custom biome has according to a plugin author
like if I make a biome and call it skibidi can another plugin detect the skibidi biome in the world via api?
torn shuttle
they are not enums
young knoll
Oh wait no they are an interface now
sullen marlin

young knoll
Then yeah maybe
torn shuttle
so the key can be arbitrary?

Yes

finally I can make the skibidi biome we've all been waiting for

What about it?
sly topaz
are custom ones like from datapack or plugins also in the minecraft namespace or their own?
young knoll
Their own
torn shuttle
well if I want it to be able to detect the biome correctly I still need to provide the right key in the namespace
and I can only do that if it is provided
inner mulch
what should the hash implementation be based on if not its value
memory adress
sly topaz
memory adress
the opposite, a hash value should never be based on the memory address if one can help it lol
the default one does because that's the only way to ensure different instances have different hashes, but you don't want that for the most part
inner mulch
ok
sly topaz
a hash code should be a representation of the object in question, that is the sum of its field + some arbitrary prime numbers for uniqueness sake
young knoll
This is why mutable objects don’t make the best map keys

Hello, I have a small problem that I have had for days and I have not been able to, I have created a plugin that records your characteristics such as deaths, murders, your uuid, among other things, and everything is fine, when you enter it creates the row for each player, the problem is when updating the statistics, when you die it has to increase the deaths variable, but it does not, in the database it will always be 0

Oh no! You ran into a problem. But no worries, people are willing to help, but first they need to see your code. This is because otherwise, they would be providing help based on guesses instead of concrete knowledge. Whether it be a compile error, runtime error, or an unexpected output, I'm sure that if you were to provide code, you'd receive a quick solution.

You can use the discord code block format to display code or just text in a more pleasing way:
```java
public class MyPlugin extends JavaPlugin {
@Override
public void onEnable() {
}
}```
Becomes:
public class MyPlugin extends JavaPlugin {
@Override
public void onEnable() {
}
}```Oof ow my main thread database interaction
strange barn
I'm sorry I didn't know that
sly topaz
I was about to comment, yeah
strange barn
Does anyone have any idea why my deaths variable isn't increasing?
young knoll
You’re using an insert statement to save the data
Which is probably creating a new row or throwing an exception because of a duplicate key
Use an update statement or the ON DUPLICATE KEY function
Also do your database interactions async
sly topaz
- DON'T do sql queries in the main thread as Coll said
- Use a try-with-resources for those prepared statements
young knoll
You also may want to close the connection after using it
I don’t remember the standard for MySQL since I normally use HikariCP
sly topaz
Use an update statement or the ON DUPLICATE KEY function
that'd depend on the database in question, you'd do ON CONFLICT for postres
OR REPLACE INTO for sqlite
or if you want a "SQL-standard" there's merge into apparently, not sure how is the support for that tho
wet breach
I don’t remember the standard for MySQL since I normally use HikariCP
if it can support enough connections, then odds that left open connections cause issues is pretty low. But the standard is to close connections you are done with otherwise they are left open for like 30 seconds (TCP default timeout)
young knoll
SQL is always everything but standard
strange barn
What do you mean by that queries should not be made in the main thread? sorry for my ignorance
young knoll
It’ll cause the thread to stall until it’s conplete
Normally you’d use something like a completablefuture
sly topaz
and you don't want to stall the main thread, since it handles all the server logic, inclduing loading chunks and among other things
strange barn
Could you give me an example of how a query would be made?
import org.bukkit.Bukkit;

} catch (SQLException e) {
e.printStackTrace();
}
}
}
public void start() {
// Ejecuta la tarea en el hilo principal de Spigot
this.runTaskAsynchronously(YourPlugin.getInstance());

}```would it be something like this, in a task?
sly topaz
private CompletableFuture<Void> savePlayerAsync(PlayerModel model) {
return CompletableFuture.runAsync(() -> {
try (PreparedStatement statement = databaseConnection.prepareStatement(
"INSERT INTO player (uuid, name, deaths) VALUES (?, ?, ?) " +

statement.setString(1, model.getUuid().toString());
statement.setString(2, model.getName());
statement.setInt(3, model.getDeaths());
statement.setString(4, model.getName());
statement.setInt(5, model.getDeaths());
statement.executeUpdate();
} catch (SQLException e) {
throw new CompletionException(e);
}
});
}
this is how your savePlayer method would look if done off the main thread
strange barn
aaa, so it is not necessary to create a separate class?
sly topaz
not necessarily, no
strange barn
The same method is executed in another thread
thanks bro for taking the time thanks
sly topaz
I just made claude generate an example so no worries lol
for anything that returns something, you'd use supplyAsync instead of runAsync btw

INSERT INTO player (uuid, name, deaths) VALUES (?, ?, ?)
ON DUPLICATE KEY UPDATE

My beloved 
sly topaz
and then to actually use the result, you'd use:
// put this somewhere in your plugin
public static final Executor MAIN_THREAD_EXECUTOR = task ->
Bukkit.getScheduler().runTask(YourPlugin.instance(), task);
savePlayerAsync(playerModel)
whenCompleteAsync((result, exception) -> { // the result is Void in this case so we don't really use it
if (exception != null) {
getLogger().severe("Failed to save player: " + exception.getMessage());
} else {
getLogger().info("Player data saved successfully: " + playerModel.getName());
}
}, MAIN_THREAD_EXECUTOR);
this is how you'd use the result of whatever query you may use
in java 23 with previews I could just use _ for that result 😔

onProjectileLaunch event when you throw an egg, how can you get the item since it could be thrown from the offhand or mainhand
slender elbow
that's the cool part, you don't, unless you add a manual check, but that isn't really guaranteed to yield proper results
barren peak
so its just not possible?
barren peak
not *reliably*
since you can only launch projectile from offhand if there is not a projectile in mainhand could you possibly use that to check?
barren peak
is there a way of checking if an item is a projectile?
slender elbow
pretty sure there's an edge case where if you're using the last projectile the used hand will be empty in the event
slender elbow
i might be wrong
barren peak
Ah I figured it was before that since the event is cancellable
yeah I thought so too. and it seems to be working that way
slender elbow
let me check
on my totally unmodified spigot source, not spigot fork, i would never
barren peak
bc I can throw last projectile and it still says item in hand
young knoll
Ah yes only spoon
barren peak
ok so is there a way to check if an item is a projectile just from itemstack?
slender elbow
this code is a mess
young knoll
I think you can just hardcode some materials
Not ideal but I don’t think there’s a tag for it or anything
barren peak
Not ideal but I don’t think there’s a tag for it or anything
alright that sucks. thanks guys
barren peak
charge, arrow
slender elbow
okay so it seems that the item is not yet consumed in that event
or, i guess it depends on the item
for eggs at least

eggs seem to work so its working for me

i guess it would fire at the start of the launch even if you cancelled it for things like tridents & bows. but for eggs it should work right?

couldn't you just check for the interact event instead
ah you already thought of that
you'd have to save the item in interact within a map or something and check for it in launch event
kinda annoying but it is what it is
young knoll
Ideally we could expose the shooter, item, and hand to the event
But I’m not familiar with what the internal code looks like in this case
kind hatch
I am looking at it currently and it does not look like you would expect it to.
CraftEventFactory is quite the class
sly topaz
can't you just cast it to ThrowableProjectile and getItem on it
young knoll
We love CraftEventFactory
young knoll
can't you just cast it to ThrowableProjectile and getItem on it
I don’t think that stores any data about the thrown item
But I could be wrong
sly topaz
it stores the item
not sure if it is linked to the item in the inventory at all or it is a clone, but it does give you an ItemStack instance
young knoll
Exactly
wet breach
Ideally we could expose the shooter, item, and hand to the event
Problem with exposing item in the launch event if we are not going to add or change code is that most of the time it would be null since the item would be gone
sly topaz
wouldn't it be air in that case
sly topaz
I guess giving you the hand is good enough

in the few cases I checked the event is fired before the item is consumed

does that expose the arrow item used?

Yes iirc

yeah it has getConsumable
wet breach
in the few cases I checked the event is fired before the item is consumed
Right but unless you cancel the event it cause issues if you tried to do something with the item which is unexpected behavior as far as the event goes
slender elbow
i mean, it will spawn the entity after the event is called
so if you alter the itemstack it'll use the altered one
(which sounds stinky)
or
err
no
the entity is already spawned
the whole thing stinks
wet breach
Lol
young knoll
Could just expose a read only copy of the item
wet breach
Could just expose a read only copy of the item
That could be a solution
young knoll
How does the bow event handle things
Afaik it exposes the arrow item even though the arrow entity is already spawned
sly topaz
if it is a read only copy then there's no difference between that and ThrowableProjectile#getItem no?
young knoll
Depends if that actually contains the data of the held item
summer scroll
Could we just check ProjectileLaunchEvent get the shooter get item in main hand?
wet breach
Afaik it exposes the arrow item even though the arrow entity is already spawned
This because the game handles bows differently
young knoll
Or if it’s just a basic copy of the held item
young knoll
Could we just check ProjectileLaunchEvent get the shooter get item in main hand?
Offhand
summer scroll
Or that
summer scroll
To get the data you know and then apply pdc to the projectile
young knoll
Okay then main hand first
Do you only throw one if both hands are holding a throwable item
summer scroll
Yes I think
wet breach
Reason the bow returns an itemstack is because the arrow is in the inventory when you fire a bow.
summer scroll
Main hand first
young knoll
Well then assuming the event is always called before the item is removed that should be reliable
A little awkward but it works
wet breach
Well then assuming the event is always called before the item is removed that sh...
Yeah the removal of the arrow happens after the event or when the projectile is spawned.
So you fire the bow, projectile is spawned then arrow removed
young knoll
This is about directly throwable items
worthy yarrow
dawg
young knoll
But it appears they also function that way, so exposing the item should behave the same as the bow event
worthy yarrow
wait
wet breach
I know, just explaining how its different for bows lol.
With throwables the code is swapped for when item is removed and entity spawned. If i recall
worthy yarrow
Is there some sort of bow.getCharge() that returns a vector object perhaps?
wet breach
I could be wrong been a while since i have looked at it in depth
worthy yarrow
Is there some sort of bow.getCharge() that returns a vector object perhaps?
I'm probably just wishful thinking here
wet breach
Is there some sort of bow.getCharge() that returns a vector object perhaps?
getForce()
But it gives a float

0-1 I believe is the range for that float

anyway, apparently BlockDispenseLootEvent doesn't actually know about the loot table the block is spitting out. is there a way to get the loot table actively dispensed from a vault block?
vaults dispense multiple drops which can variate in loot table, but there doesnt seem to be an event that actually associates each drop with their respective loot table
smoky anchor
The loot table is stored in the block. Can you not get the block and then the loot table ?
I might be misunderstanding you.
hushed spindle
its not stored in the block because vaults/trial spawners can spawn from several loot tables
they spawn a couple drops from the "common" loot table and then maybe some extra drops from "rare" and "unique"
so theres not 1 loot table
young knoll
Is it stored in the vault

the vault block data does not have a loot table

depends on how you define cool
for example lately I work a lot with bedrock at work and most networks just use custom player skins with geometry for custom mobs

the entity component system at work is also clever

yea that's what i meant

We can make entities hold data and stuff
Attach "templates" to entities that apply components in case we want persistent components
there's a whole ecosystem around entities and it's pretty much all I made for the past 6 months

how do you apply fall damage to a player that has canFly
you need to handle it yourself
with ground distance
I made it so that it disables flight when falling higher as some float and then re enables flight
// Perform ray tracing to check distance to the ground
RayTraceResult rayTraceResult = player.getWorld().rayTraceBlocks(
player.getLocation(),
new Vector(0, -1, 0), // Straight down direction
10, // Maximum distance to check
FluidCollisionMode.NEVER,
true // Ignore passable blocks like grass
);
// If ray trace hits the ground, check the distance
if (rayTraceResult != null && rayTraceResult.getHitBlock() != null) {
double distanceToGround = rayTraceResult.getHitPosition().distance(player.getLocation().toVector());
// Check if fall speed and distance indicate fall damage
if (fallSpeed > 0.15f && distanceToGround <= 5 && distanceToGround >= 3.25f) {```You can remove the fall speed tho and it would work with distanceToGround depending on your needs.

I don’t think the NBT format has changed in a long time
The contents inside it might no longer be valid, but the file format should still be fine

It could be encoded wrong, or maybe Maven doesn't know what to do with it

I'm no good with how enchantments work with Spigot, but you can figure it out

Everyone has their own way of doing things but when it comes to Java, you must follow the rules in ways things are written and constructed. This makes it much easier for developers to read your code.
You won’t get hired if you do not know how to follow coding conventions, that’s for sure lol
sly topaz
but in the end you'll find people that will bully you into oblivion for having bad naming practices or unorthodox formatting overall. It just gets in the way of people actually trying to help you if you go against these practices that are well in-grained in programming for no specific reason

Or just ignore the message

You can also just do it when they first join

If you have minecaft, just join and then exit, in your world player data folder it has your uuid
sly topaz
yeah but I want to look at it with ImHex to see if it'd be hard to parse

I have JNBT posted on my repository
sly topaz
I've looked at them before but they all seem to be lacking some support for the new chunk format among other things

But i wouldn’t bother looping over 10k files when i can reset it on first join
young knoll
Yeah mine doesn’t support the new chunk format either
Because it has compressed NBT data inside compressed NBT data
river oracle
Oh my
kind hatch
NBT seems pretty straightforward. But yea, you could just update stuff onjoin
young knoll
Each chunk is compressed and then the entire region is compressed
sly topaz
wonder if they do that on purpose
I doubt just layering compression algos like that has much benefit lol

My question tho was to prevent the error from coming up, assuming recipes are read on join, how would you reset that before it’s read 🤷♀️
young knoll
It’s not really an error
The game just complains about an unrecognized recipe and then removes it
wraith delta
Tried to load unrecognized recipe: ResourceKey[minecraft:recipe
i know i can ignore it but i minus well be able to reset them before the error shows because i need ppl to start fresh anyways
young knoll
Then just remove the player data files?
wraith delta
Then just remove the player data files?
I want to sync inventory,enderchest,armor without a database. (looping through on join to remove enchants or cheatable stuff) this way ppl can keep their collectibles

Why do unlocked recipes matter
wraith delta
Why do unlocked recipes matter
fresh server reset and so id want the stats to be new
young knoll
Yeah but unlocked recipes don’t actually do anything
Unless you are using doLimitedCrafting
kind hatch
They show up in the recipe book. :3

bugged with hundreds of custom recipes from a old plugin, some ppl have stats like 1000levels, score, health.
easy to reset on first join.
young knoll
Also fun fact
Advancements are used to unlock recipes
Which means the game has 100s of invisible advancements
kind hatch
They unlock recipies??
young knoll
Mhm
kind hatch
I thought they just give rewards
wraith delta
its a new world i didnt transfer advancements
young knoll
They can do a lot of things
I keep forgetting the official game has a Bukkit reference
wraith delta
Besides making a loop to undiscover them all, is there a more performant method?
kind hatch
Probably not. You'd have to iterate over your entries anyways considering it's a list.
wraith delta
ok np
young knoll
undiscoverRecipes(getDiscoveredRecipes)
wraith delta
Set<NamespacedKey> knownRecipes = player.getDiscoveredRecipes();
player.undiscoverRecipes(knownRecipes);
```yea i did similar like this
