You can create custom persistent data types on your own, or use one of the many libraries available which have implemented those which match your needs.

can you write null?

Unfortunately no, with just how anvils and such work in general the curent inventory API doesn't lend itself nicely to such things. If you want to avoid NMS use a library like AnvilGUI
which does all the NMS for you. If you're intrested in doing something yourself with nms all you really need to do is open an anvil container
// Note NMS 1.20.1
@Nullable
public static InventoryView openWorkstation(@NotNull final CraftHumanEntity entity, @NotNull final Block block, @NotNull Function<BlockPos, MenuProvider> exception) {
final BlockPos position = CraftLocation.toBlockPosition(entity.getLocation()); // arbitrary block location
MenuProvider provider = block.getMenuProvider(null, entity.getHandle().level(), position);
if (provider == null) {
provider = exception.apply(position); // applies certain exceptions this is advanced for a few exceptions you could remove this
}
if (provider == null) {
return null;
}
entity.getHandle().openMenu(provider); // opens menu
entity.getHandle().containerMenu.checkReachable = false; // ignores if the container is even in range of you
return entity.getHandle().containerMenu.getBukkitView(); // gets the bukkit view
}``` I made this method to open any container but anvil specifically would look something similar
Usage in this case would be pretty simple for making an anvil view thats functional
```java
openWorkstation((CraftHumanEntity) entityHuman, Blocks.Anvil, (__) -> null);
you can either apply your items to the menu provider prior to opening it to the player or just appling it after (which is what I do as I don't feel like dealing with nms stacks even with the bukkit translation methods)

is there a way to know which number they click inside the InventoryClickEvent after knowing it's a ClickType.NUMBER_KEY?
i just want to cancel the key 9 since the players will have an item in that slot that can't be dragged or dropped, but also want to cancel them from using the number key to move it.

Ok ive done a very simple test

public FakeArmorstand(Location loc) {
ServerLevel level = ((CraftWorld) loc.getWorld()).getHandle();
this.nmsBackbone = new ArmorStand(level, loc.getX(), loc.getY(), loc.getZ());

public void showTo(Player player) {
ClientboundAddEntityPacket spawnPacket = new ClientboundAddEntityPacket(this.nmsBackbone);
((CraftPlayer) player).getHandle().connection.send(spawnPacket);
}

And i get both left and right click packets for this fake armorstand.
No problems.

It’s hard to answer a programming question without code
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.

A class itself does nothing. Its just a blueprint which describes how an object should look like.
Every time you create an object (instance) using this class, it has its own separate variables and states.
Here is an example:
// A simple class with a variable, a setter and a getter
class Bus {
private int speed;
public void setSpeed(int value) {
this.speed = value;
}
public int getSpeed() {
return this.speed;
}
}
// Creating an instance of class 'Bus'
Bus busA = new Bus();
// Creating another instance of class 'Bus'
Bus busB = new Bus();
// Every Bus instance has its own state.
// Setting the speed of busA
busA.setSpeed(50);
// This will still print 0 because they have each their own 'speed' variable.
System.out.println(busB.getSpeed());
This is basic Java to be honest
upbeat fog

Do you create only one instance of your Listener?
Otherwise you should overthink your design.

"node that the player is facing" What does that mean exactly.
Sorry for late response. The node is essentially a step towards the goal. Each node contains a cost (distance from current node, and distance from end node) I want to add another heuristic for the way the player is facing somehow. Higher cost means the node is less likely to be explored, so the PVP NPC should try to go to the sides and behind the player to attack instead of approaching head on. This introduces a new issue of yaw and pitch tho.
If a player is facing in the direction of a node with a low cost, it should increase the cost of that node by ALOT, but this also causes issue with concurrency since it requires changings while the path is being computed.
The algorithm is a modified version of A* pathfinding optimized to reduce computational load.
Essentially what im trying to accomplish is, if the player is directly facing the computed path, the node cost need to change in real time.

small current
It really makes no difference in teh end. Its micro optimizations
it is not micro optimizations
you shouldn't call that micro
eternal oxide
Do you understand what a micro optimization is?
small current
forEach is not made to slap at every part of the code
when the place is right, use it
eternal oxide
a micro optimization is when you change your code to achieve the tiniest of performace increase. The difference between a for loop and a forEach is so minuscule that making those changes is a micro optimization (except in very specific cases).

Well you are wrong
eternal oxide
Please point out where I'm wrong
small current
its is not SO minuscule
first of all, it is visibly slower
second, using it too much makes your code unclean
eternal oxide
when in the majority of cases it compiles to the exact same byte code it is minuscule.
small current
but using it right, it makes it clean

no it does not
eternal oxide
uh yes it does.
small current
nuh uh
slender elbow
first of all, it is visibly slower
if you run it in a potato and in interpreter mode, sure
otherwise, not really, no
small current
otherwise, not really, no
it is
slender elbow
benchmark?
slender elbow
i do, every day
small current
high amount of players
using in wrong places
like on player join
or death
it sure has a visible problem
forEach shouldn't be used everywhere
this is all im saying
slender elbow
forEach is not going to make that run any slower than a regular for loop
small current
some slap it all over their code
eternal night
I mean, if you replace a Set#remove with that
obviously
but compared to a normal for-each, i have no idea how large that set would have to be
to be able to measure a difference
eternal oxide
The difference is negligible (as I already said) unless it's a very specific circumstances. https://medium.com/@KosteRico/for-each-loop-vs-foreach-method-in-java-11-which-one-is-faster-8a5120c0c8c3
slender elbow
i mean, forEach is literally an enhanced for-loop
river oracle
for is faster guys 🤓 I also use short and byte for most of my numbers to save memory
eternal night
but but
it calls a lambda
checkmate
everyone knows those are black magic that is very slow 
eternal oxide
anything with a hash is pretty much identical
eternal night
eternal oxide
Yes it's not clean but we were discussing performance and you claiming changing between is not a micro optimization
smoky oak
anyway, on a different topic...
I'm about to do some location nonsense. What is the best way to check if an object is within a certain distance to another? Bounding box, then call location.squaredDistance?
read best = fast
eternal oxide
distanceSquared
eternal night
AABB checks can certainly help you a bit if you expect to most of the time not hit anything
tho, if you are gonna be constructing those instances a shit load of times
stick to distanceSquared
eternal night
I mean, that would be terribly stupid
smoky oak
wait wdym with AABB then
eternal night
Well you'd obviously use the getNearbyEntity stuff
given that that call can optimize based on chunks
so instead of all entity you'd only get back the entities in the nearby n chunks, depending on the radius
small current
Yes it's not clean but we were discussing performance and you claiming changing ...
it is not so little
when it comes to big amounts
eternal night
I s2g
eternal night
you cannot reach the amounts where that would remotely matter
you get a single added lambda call which
might as well be as fast as the native method call
river oracle
you cannot *reach* the amounts where that would remotely matter
well actually ☝️ 🤓 I just ran a jmh benchmark over 10 trillion elements and forEach is slower

funnily enugh at small numbers ArrayList is actually really fast

but does it set

you could also make your own Array backed Set implementation (but really just use hashset lol)
