compileOnly means the classes are already provided on runtime. (The server jar includes the spigot api ofc)
implementation means that you copy the classes into your jar so you provide them on runtime

For AtomicReference you might need a TypeAdapterFactory which can be quite tricky

You should not register a serializer for your KingdomPlayer.
Work your way up. Start with the lowest level and let Gson do the rest.

You should not work with references in data classes at all.
So instead of the player ref you should use the players UUID.
There is also 0 need to make PlayerData an atomic unless you intend to set it a lot from different threads. Which you should avoid. Make it final.
eternal night
Well yea but that isn't really how you do gson
tardy delta
started with it yesterday hehe
hmye lets remove that atomicref
conclure recommended me that 🤔

Immutability is key here. It automatically makes your data thread safe as well. Only synchronize when you really need to.
Gson can handle immutable classes quite well.
tardy delta
only thing of the kingdomsplayer which is mutable is the whole playerdata class
that why i made a seperate class

wrapping a mutable type in an atomic ref does not really help

Replace it. Use a setter to set the value.

replace what?

it's loaded from the persistent storage and set when creating the player object

actually i forgot why i did that but conclure told me smth about it lmao 🤔

Just... remove all the references and use final fields.
Then Gson will be able to serialize everything on its own as long as the nested classes are Pojos and you
have type adapters for the bukkit objects.

If you want a type adapter factory for abstract classes and interfaces just ask me later.

You can do thousands of lookups on a hashmap every tick and never notice it in your timings. We are speaking of a few micro seconds here.

When you test other parts of your project that rely on the database you subtitute the database implementation with a mock one that you entirely control so we can get the test flow of "Assume everything else works, does this function/module also work?"
We essentially try to only test the stuff we actually want to test

For the manual ones you probably dont mock stuff

I'm working on a plugin for a custom item-type that the player can interact with by left/right clicking the air while holding that specific item. My questions is mostly if it's fine performance wise to have an event listener for this and filter out events where the item is incorrect.
Say the item is diamond, but the eventlistener checks for the player clicking the air with a diamond. Players will always be clicking with lots of random stuff, so will it be a significant impact on performance if it picks up that event and checks if it's a diamond?
I ran a test for the eventlistener, and it would also pick up events where I was clicking blocks, not just nothingness. I assume because there are airblocks everywhere around the player that get clicked as long as you're not interacting with something

ItemStack#clone() exists. However, it looks like you are already using a copy.
You may want to have stricter checks on what inventory you are clicking in.

not the item in hand

Then you may want to avoid grabbing the item from the player's inventory if possible. (Unless your system gets the item from their inventory)
I still believe it's an inventory click issue. InventoryView#getTopInventory() should help you with what's being clicked.

so essentially just a way of accessing the instanced plugin
Just think about what your plugin can do and provide useful methods for other devs. For example if you are writing a protection plugin then add methods like

or
public PortectedRegion getRegionByName(String name)
or

There are two approaches. Either write your plugin data driven from the beginning and make everything foolproof so other devs

You can take a look at the facade pattern for some inspiration.

Oftentimes you need to return what was parsed along with the number of characters it parsed through so you can jump ahead by that much
There are lots of other such cases

Functions can take multiple values, why shouldn't they be able to return multipl...
that's something totally different from what I thought you wanted to do. What you wrote earlier, I thought you wanted to do something like this
/**
* Returns the original "input" String, and the lower case variant of that String
*/
public String, String toLowerCase(String input)
and obviously that makes no sense. Maybe I misread what you wrote, or you explained it badly, Anyway, this is what I thought you wanted to do, and you probably understand that I thought that this makes no sense, lol

you should've named it "ArrayFactory"
record SmallNumber(boolean isOne, boolean isTwo, boolean isThree, boolean isFour, boolean isFive, boolean isSix, boolean isSeven, boolean isEight, boolean isNine, boolean isTen) {
}

Oftentimes you need to return what was parsed along with the number of character...
because here you said "you want to return what was parsed" and I was like "yeah but what you parsed is what you have passed to the method. no need to return that again, since whoever called this method, already has this object", you know, lol

```java
record SmallNumber(boolean isOne, boolean isTwo, boolean isThree, boolea...
what happens if two of those booleans are true?
or even three 😮
or 7
echo basalt
```java
record SmallNumber(boolean isOne, boolean isTwo, boolean isThree, boolea...
public enum ByteNumber {
ZERO,
ONE,
TWO,
THREE,
FOUR,
FIVE; // TODO: addm ore
public byte byteValue() {
return ordinal();
}
public boolean isEqual(byte number) {
return ((Byte) byteValue()).equals(number);
}
}
we should rewrite it for a sum of numbers
waxen plinth
what happens if two of those booleans are true?
Superposition
echo basalt
to represent any number
record SmallNumber(boolean one, boolean two, boolean four, boolean eight, boolean sixteen, boolean thirtyTwo)

Will the PlayerRespawnEvent activate in any circumstance besides a player dying?

I don't think so

why am i getting this error for this simple line of code?
slate delta
Exemple i want (in code) get the amount of xp need for repair at certain %
Any ideas?
tender shard
I guess your pitch is either Double.POSITIVE_INFINITY or Double.NAN
print out the pitch before passing it to whereever you pass it

lol yeah sometimes it has a stroke. But sometimes it does extremely awesome stuff. For example, it wrote this ENTIRE class (with maybe 2 or 3 lines I had to adjust) and IDK how it knew what I wanted to do.

how would i knock a mob back like 1 block? basically hitting them with a fist or smth
echo basalt
if you want realistic knockback
I have a util for that
that I need to constantly rewrite because this isn't 1.12 anymore
but it's easy to port

I want get in code the amount of xp needed to repair the item at certain %
Exemple : +10% durability = 3xp level
echo basalt
get the total level

But how?
echo basalt
*= durabilityBonus

if you want realistic knockback
just want like a simple 1 block push

velocity?? could be wrong
echo basalt
just make a vector in the direction
desert frigate
echo basalt
and call setVelocity
desert frigate
target.setVelocity(target.getLocation().toVector().subtract(new Vector(1,0,1)));
i have no clue how vectors work
echo basalt
uhh no
Vectors are a 3d displacement point relative to any other 3d point
They can be treated as relative to 0,0,0 which makes them effectively an absolute position
You can add, subtract, multiply, divide and normalize these displacements
Normalizing means it grabs the current points and divides them by its length, effectively making a vector with the length of 1
For velocities, it's quite simple
target.setVelocity(new Vector(0, 1, 0)); will set target's velocity to an offset of 1, in the vertical axis
meaning the target will fly up
fierce dock
Ik that creating custom potions is difficult and I was wondering if someone could point me in the direction of some type of tutorial/function/whatever.
desert frigate
Normalizing means it grabs the current points and divides them by its length, ef...
So shouldn't I just use (1,0,1)?
orrrred
echo basalt
try it and see
tender shard
So shouldn't I just use (1,0,1)?
a vector of 1,0,1 will NOT have a length of 1, if that's your question
desert frigate
try it and see
yeah it did nothing, matter a fact it crashed the server lol
echo basalt
you have some weird server

you have some weird server
its a local 1.18 server

Why does cancelling InventoryClickEvent in the creative PlayerInventory duplicate the item?
setting the cursor to null does nothing aswell

how would i set a players inventory?
modest garnet
ok well how would i find a solution to do this?
iron glade
tell us what the problem is before asking for a solution
modest garnet
tell us what the problem is before asking for a solution
there is no problem, i get a players inventory and i store it in a Map. then i clear the inventory ("do something") and then i need to set the players inv back to the inventory in the Map
iron glade
get the contents of the inventory from your map and add them to the player's current inventory
modest garnet
get the contents of the inventory from your map and add them to the player's cur...
how do i ensure there all in the same slot etc
echo basalt
getContents returns an array
setContents takes such an array
the array indexes match the inventory slot indexes
iron glade
^ easy as that

Hi i was wondering how Player#getBedLocation works. If it works by server or by world. because im trying to send a player to their bed no matter if it's in another world

What's the easiest way to get a specific NBT tag from an entity?
worldly ingot
Depends. All the vanilla NBT tags are abstracted out into just simple getters
worldly ingot
Alright so you're already in NMS. It should have a getTag() method
carmine nacelle
When it spawns, im setting a custom nbt tag on it which works fine, however... when the bees exit the hive they are no longer the custom entity but they keep their nbt data
I basically need to check if they SHOULD be a CustomBee so I can cancel CreatureSpawn and spawn my own
worldly ingot
Right because vanilla spawns a regular bee
worldly ingot
Correct
carmine nacelle
Nice, thanks chief
worldly ingot
Bukkit doesn't expose arbitrary NBT tags (exception to the PersistentDataContainer but that's under a PublicBukkitValues tag, nothing on root)
carmine nacelle
It's entity#getTags right
worldly ingot
It should return an NBTTagCompound (or CompoundNBT depending on the mappings)
getOrCreateTag() iirc
carmine nacelle
Returns a Set<String>
worldly ingot
Yeah those are probably scoreboard tags
carmine nacelle
@worldly ingot I cant find the import for the nms bee
CraftBee doesnt have getTag
worldly ingot
It doesn't, right. You'll have to call getHandle() on it
