why don't they make it an interface then?

They just reference what is implemented on the server side
jovial warren
onyx loom
smooth brains bardy, smooth brains
jovial warren
should be an interface if it's always overridden and requires all of the defined methods to be overridden

Okay, but we're not talking about implementations

just the reference to the existing object in the api vs the server
implementations are children to the existing object
jovial warren
Spigot should be an interface in the API
there's no reason to not have it be an interface
hallow crane
Okay sure
that's not what im arguing
You may be right
in fact I agree
but md4 0head

what are you arguing then?

the reason it's not an interface on the api side
is because it's not on the server side

ItemStack itemStack = new ItemStack(Material.DIAMOND_SWORD);
player.getInventory().addItem(itemStack);
What if I wanted to do a bunch of items?
Would I have to create an itemstack from each material?
Surely not

Thanks to you both

That's actually not bad, it's kinda similar to Kotlin react
div {
h1 {

}
}
yea I feel like its core concept is pretty much that of react, it just builds onto that
Here you dont control anything, you define the view once, and then the only thing you can do is modify the model on events
ocean quartz
Does it compile to wasm?
old wyvern
Compiles to js I think

By any chance do you know why this method isn't being recognized? When I type the default command as well as a player name I want this to run but instead I get "This command does not exist"
@Completion({"#players"})
public void swordOther(final Player player, final Player target) {
meta.setDisplayName(ChatUtil.color("&cThis sword belongs to &4" + target.getName() + "&c."));
lore.add(ChatUtil.color("&cGiven to &4" + target.getName() + " &cby " + player.getName()));
itemStack.setItemMeta(meta);
target.getInventory().addItem(itemStack);
player.sendMessage(ChatUtil.color("&6Sword successfully sent."));
target.sendMessage(ChatUtil.color("&6Sword received from " + player.getName()));
}
Oh, i mean yeah you need either @Default or @SubCommand those are required
oak raft
Ah okay that makes sense
Do I need to fill the SubCommand() value though? I don't want another word besides from the target player name
ocean quartz
Yeah if you do subcommand you need to fill
Can you show me an example of your command?
oak raft
So basically if I type /sword it'll give me a custom sword. However if you type /sword <player> it'll give them a sword
Or do you wanna see what I've written
ocean quartz
Oooh
@Default
public void sword(final Player player, @Optional @Completion("#players") final Player target)
Yeah
oak raft
๐ฅฒ
oak raft
Okay so under the method, I would write as if the player is typing the command by itself right?
ocean quartz
If target is null it means the player did either /sword or /sword invalidPlayer

itemStack.setItemMeta(meta);
player.getInventory().addItem(itemStack);
player.sendMessage(ChatUtil.color("&6There's your sword kid."));
} else if (target != null) {
meta.setDisplayName(ChatUtil.color("&cThis sword belongs to &4" + target.getName() + "&c."));
lore.add(ChatUtil.color("&cGiven to &4" + target.getName() + " &cby " + player.getName()));
itemStack.setItemMeta(meta);
target.getInventory().addItem(itemStack);
player.sendMessage(ChatUtil.color("&6Sword successfully sent."));

yeah ik that, but why do we always end up with 1 there

Bukkit doesn't use absolutes though (got this from Bukkit's Vector)
and I'm gonna guess it's doesn't always return 0
lunar cypress
by | I mean the euclidian norm here
lunar cypress
you calculated it
jovial warren
oh
lunar cypress
What this implies is that your thing you call min/max on is always <= 1
jovial warren
jovial warren
ah, I thought that said >= lol
lunar cypress
Also you probably want to swap min and max there?
jovial warren
I struggle reading those inequality signs sometimes for whatever reason
lunar cypress
what is it that you're trying to calculate exactly?
jovial warren
Also you probably want to swap min and max there?
ah yes, that'll be it
jovial warren
what is it that you're trying to calculate exactly?
the angle between two vectors
lunar cypress
Why min max
jovial warren
that's just what Bukkit uses
Doubles.constraintToRange (from Guava)
public float angle(@NotNull Vector other) {
double dot = Doubles.constrainToRange(dot(other) / (length() * other.length()), -1.0, 1.0);
return (float) Math.acos(dot);
}
this is from Bukkit
lunar cypress
Idk what the point of this is exactly, but you don't need it for the angle
jovial warren
jesus christ
I wonder why Bukkit forces it between that range
wait a minute... isn't the cosine of an angle always between -1 and 1? the same as all the other trigonometric ratios?
jovial warren
arc cosine takes a cosine as an argument
lunar cypress
"inverse", yeah
jovial warren
Special cases:
- `acos(x)` is `NaN`, when `abs(x) > 1` or x is `NaN`
yeah that might explain it
jovial warren
yeah it shouldn't, but ya know, floating point rounding errors
lunar cypress
because of the inequality I mentioned earlier
fair enough
the same as all the other trigonometric ratios?
tanwould like to have a word with you

can the tangent of an angle be above 1?

jovial warren
NaN isn't a mathematical concept (afaik), it's a CS concept
jovial warren
also, I wonder why Bukkit has an EPSILON value (0.000001) that accounts for floating point errors
lemme show you what I mean
lunar cypress
because they've decided on that delta /shrug
jovial warren
is that a normal thing to do?
lunar cypress
yes
old wyvern
Yes'
jovial warren
so I shouldn't be using == to check floating point numbers then?
lunar cypress
absolutely not
old wyvern
mhm
jovial warren
(I mean Kotlin's ==, which calls equals under the hood, a.k.a object equality in this case, not reference equality, just for clarification)
lunar cypress
doesn't matter in java either if we're talking primitives
old wyvern
equals doesnt do a range check either
jovial warren
override fun compareTo(other: Position): Int {
if (x == other.x && y == other.y && z == other.z) return 0
if (x > other.x && y > other.y && z > other.z) return 1
if (x < other.x && y < other.y && z < other.z) return -1
return 0
}
```this is `Position`'s current `compareTo` functionpretty terrible ik, and could definitely do with some improvements, but I guess it works
lunar cypress
That is a bad idea
jovial warren
which part?
lunar cypress
3 dimensional vectors do not have total order
jovial warren
so they shouldn't be comparable then?
jovial warren
because I use that to check if the new location sent by the client has changed since the last position sent by them lol
lunar cypress
then you check equality
old wyvern
so they shouldn't be comparable then?
maybe interms of distance from the origin
lunar cypress
with an epsilon
lunar cypress
maybe interms of distance from the origin
still wouldn't do that, sort of arbitrary
and I believe it violates the contract of comparable
old wyvern

I need to check if the X, Y and Z coordinates have changed, that's it
lunar cypress
It is strongly recommended (though not required) that natural orderings be consistent with equals
I would adhere to that
old wyvern
mm
lunar cypress
I need to check if the X, Y and Z coordinates have changed, that's it
yeah just check that then and don't say which is less or more
prisma wave
also, I wonder why Bukkit has an `EPSILON` value (`0.000001`) that accounts for ...
yeah calin has a solution for that
lunar cypress
lmao
old wyvern
lol
jovial warren
so just fun areEqual(first: Position, second: Position) = first.x == second.x && first.y == second.y && first.z == second.z should do then?
jovial warren
I'm not bothered here about being 0.000001 out lol
the client will never send a position change that would cause problems with those inaccuracies
lunar cypress
That's not what it's for
old wyvern
Its not an issue with the client
lunar cypress
It's the opposite
jovial warren
ah, checking if they are equal
lunar cypress
0.000001 is to tolerate mistakes
if you don't do a comparison like this it breaks for every fp error
old wyvern
Floats loose precision from normal operations because of how floating point numbers are represented in memory
It doesnt have infinite precision
jovial warren
so what should it be then? abs(first.x) - abs(second.x) > 0.000001 for all 3 coordinates?
lunar cypress
subtract, then abs
old wyvern
^
jovial warren
ah right
jovial warren
actually maybe I can use == here, since equals is the one that is overridden to use the epsilon
override fun equals(other: Any?): Boolean {
if (this === other) return true
if (javaClass != other?.javaClass) return false
other as Vector
return abs(x - other.x) < EPSILON && abs(y - other.y) < EPSILON && abs(z - other.z) < EPSILON
}

maybe you can make an extension function for Double
dunno why kotlin doesn't already have that

that's the question
but the way data classes do it currently violates the contract
