jovial warren
lol
now I gotta write up the changelog for Krypton 0.14 🥲
I made sendActionBar, sendPlayerListHeaderAndFooter, showTitle, clearTitle and resetTitle work
added some documentation for data class constructor params with @param
switched to superior Kotlin DSL
also switched the config format to HOCON instead of TOML
also just used my brain and realised that KryptonServer can be an object
so yes, the server is now a singleton 🥲
prisma wave
ew
jovial warren
well, the backend of the server anyway
dw, there's no singletons in the actual API
actually, does having it be a singleton mean I still get control over when it's instantiated?
prisma wave
no
jovial warren
right, back to a class then lol
oh btw, probably asked this 100 times before, but I should definitely swap out using the manifest's main class for a main attribute in plugin.conf right?
screw it, it's done lol
also, is it just me or is use one of the most useful extensions to I/O streams there is
return JarFile(file).use { jar ->
val entry = jar.getJarEntry("plugin.conf")
?: throw FileNotFoundException("Plugin's JAR does not contain a plugin.conf!")
jar.getInputStream(entry).use {
HOCON.decodeFromConfig(ConfigFactory.parseReader(InputStreamReader(it)))
}
}
```vs```kotlin
val jar = JarFile(file)
val entry = jar.getJarEntry("plugin.conf")
?: throw FileNotFoundException("Plugin's JAR does not contain a plugin.conf!")
val stream = jar.getInputStream(entry)
try {
return HOCON.decodeFromConfig(ConfigFactory.parseReader(InputStreamReader(stream)))
} finally {
jar.close()
stream.close()
}
it's literally try with resources
jovial warren
that's what I mean
but use is so much better than try-with-resources
so much more idiomatic
xD
also, I do love some of the hackery in this project
like avoiding using ticking to send keep alive packets by using an SES
jovial warren
lol
I'm still actually thinking about how I'd even do ticking
since I've made a vow that a "primary thread" will never exist in Krypton
well, when Krypton gets into release anyway
that will not exist
prisma wave
but `use` is so much better than try-with-resources
questionable
as someone said the other day use creates arrow code
try with resources doesnt
oblique heath
what exactly are you going to do in place of having a primary thread o.o
prisma wave
die
jovial warren
what exactly are you going to do in place of having a primary thread o.o
distribute the load across many coroutines
if I can
jovial warren
yeah ik
I could split up the world into sections and have each section be processed concurrently
but that might get expensive at scale
oblique heath
that's a lot of threads
prisma wave
jovial warren
which you can kinda just throw around
oblique heath
i was thinking
prisma wave
tfw that's literally what aether does
oblique heath
what if instead of having a primary thread
jovial warren
tfw that's literally what aether does
yeah that's what Yugi said
oblique heath
you have a primary thread pool
jovial warren
there will be a pool for handling ticking
remember though, this won't be a thread pool
Kotlin will handle the thread pool internally
I'll be using a coroutine dispatcher 😎
prisma wave
why dont we have a stateless game that can be represented as a pure function
oh wait that's game of life
ez
prisma wave
?
oblique heath
split sections dynamically based on how many tiles are in use
add a new coroutine and rebalance after a threshold is passed
jovial warren
okay you lost me with the words dynamically and rebalance xD
prisma wave
lol
oblique heath
you don't need many coroutines for a small automata
jovial warren
I'm talking about Minecraft
jovial warren
oh yeah, because the game of life and Minecraft are the same thing
Mojang has entered the room

Hey, how can I make material: change every seconds with DeluxeMenu please ?
oblique heath
anyways same point applies
oblique heath
you don't want or need 50 coroutines for a single loaded chunk
oblique heath
but thats hard
jovial warren
but I do want more than just a single thread ticking an entire world
jovial warren
it's just how they're going to stay at least somewhat in sync with each other that worries me

single-threaded ticking means Krypton's just gonna turn into vanilla though
Not true

prisma wave
no it doesn't
oblique heath
nginx runs on a single thread
old wyvern
Pretty much every game runs like this
hot hull
ticking should be sync tho
jovial warren
what makes Minecraft bad then?
oblique heath
single thread does not = bad
prisma wave
shit spaghetti code with no optimizations
old wyvern
^
jovial warren
single thread does not = bad
true, it's how you use that thread
oblique heath
aka coroutines
jovial warren
okay, so maybe Krypton can have a single thread for ticking
oblique heath
and all that stuff
jovial warren
though I want more stuff to be done reactively
old wyvern
as in?
oblique heath
it'd be nice to not have ticks at all
jovial warren
e.g. chunk loading checking, like checking whether you've crossed a chunk border, should be done reactively
or should it
position packets are sent more often than ticks run I think
also, how would I even tick?
I know Glowstone uses an SES
and vanilla just uses a while (this.running)
prisma wave
while true {
tick ()
old wyvern
^
jovial warren
while true {
tick ()
I need a way for that to halt though
prisma wave
System.exit
jovial warren
won't that keep ticking until it shuts down the main thread though?
half harness
while (isTicking())
old wyvern
It closes your application bard
oblique heath
while running {tick()}
jovial warren
while (isTicking())
okay that does literally nothing
old wyvern
Also do have some logic to make sure your application doesnt over tick
half harness
and in isTicking() it can do tick()
jovial warren
Also do have some logic to make sure your application doesnt over tick
watchdog
old wyvern
No
You dont need to shutdown the server
Just make sure you have a cap
And send warnings if it goes under
jovial warren
also, if I'm using while true, how am I gonna make it run every 20 seconds?
old wyvern
Before ticking get time
half harness
#816184747024711693 message

old wyvern
after ticking, get time
Check deviated time
Compare with thresh holds
If < normal tick time
put thread to sleep till that time
oblique heath
krypton is supposed to be a super fancy speedy efficient concurrent engine right
old wyvern
else
jovial warren
maybe Glowstone's method of using a single thread SES and scheduling to run every 50ms wasn't so bad
jovial warren
put to sleep?
oblique heath
how about going all the way and finding a way to use GPU to tick 😎
old wyvern
No
prisma wave
old wyvern
We simply dont want the thread to do anything in that interval
jovial warren
actually, Netty can still answer people's calls
prisma wave
ayyyy
old wyvern
Yes
half harness
also, if I'm using `while true`, how am I gonna make it run every 20 seconds?
why not just while (tick())
private fun tick(): Boolean {
if (!running) return false
sleepThreadStuff
return true
}
ez
prisma wave
minimal downtime
jovial warren
ticking whilst isTicking makes 0 sense
since if isTicking returns false then we're not ticking anymore
but that will only be updated if we're not ticking
half harness
then tick()
forest pecan
you could use a shutdown hook
for System.exit use a shutdown hook
and you could stop the ticking
forest pecan
while (someBoolean) is better
old wyvern
no ivan
half harness
why not just `while (tick())`
```kt
private fun tick(): Boolean {
if (!runn...
whats so bad about this 😫
old wyvern
game loops are a thing
oblique heath
well no i mean for if a thread has nothing to do
old wyvern
All the threads responsibilities will be inside the loop
forest pecan
maybe some build off others
jovial warren
const val TICK_EVERY = 50
var lastTickTime = System.currentTimeMillis()
fun start() {
// do magic
while (true) {
if (System.currentTimeMillis() - lastTickTime < TICK_EVERY) return

}
}
```right?if you want a thread to not do anything you dont want to use while(true)
jovial warren
just as an example
jovial warren

jovial warren
wow did dkim just provide some useful information for once?
forest pecan

oblique heath
```kotlin
const val TICK_EVERY = 50

why not schedule the tick for every 50 ms?
forest pecan
bardy and dkim switched braincell numbers
jovial warren
I was thinking of doing what Glowstone does and using a single threaded SES
forest pecan
everything is going to boil down to while (someBoolean) eventually whether any fancy library you use
or something similar
half harness
```kotlin
const val TICK_EVERY = 50
var lastTickTime = System.currentTimeMillis...
const val TICK_EVERY = 50
var lastTickTime = System.currentTimeMillis()
var running = true
fun start() {

while (running) {

// do tick
}
}
const val TICK_INTERVAL = 1000/20
...
while (true) {
val tickStartEpoch = System.currentTimeMillis()
tick()
val tickEndEpoch = System.currentTimeMillis()
val deviatedTime = tickEndEpoch - tickStartEpoch
if (deviatedTime < TICK_INTERVAL) {
Thread.sleep(TICK_INTERVAL - deviatedTime)
}
}
Something like this ig

can Kotlin actually interpret 1000 / 20 as a compile-time constant?
I never knew that lol
because it seems to have issues with things

Could also do val tickTime = measureTimeMillis(::tick)

Could also do `val tickTime = measureTimeMillis(::tick)`
that'll call tick won't it?

so this line
fromMaybe (-1) $ elemIndex max inputs
i get what elemIndex max inputs does, it gets the index of the largest input

pretty much Optional#getOrElse
-1 being the default value if max isn't in inputs
Except it always will be
oblique heath
is it required
hot hull
It's optional#orElse, what a noob for not knowing this

Oh whoops soz

what's return . read
old wyvern
Its not a casting, the compiler just needs a type hint at some point in the function, it can infer the rest that use the same type
old wyvern
what's `return . read`
composition
it returns a function which first applied read and then return on any given argument
return . read so takes an argument (because read takes a single argument) applys read to it, then applies return to it
oblique heath
wait so the . does the same thing as $ would?

Well no, $ is just a change in precedence

for reading an int you'd just do ```fs

oh btw, @old wyvern, you know how for ticking, you said I should use Thread.sleep?
since this is a coroutine, shouldn't I use delay instead?

can anyone explain why this most recent CoC considers a nested while + for loop in the main inefficinent, but is okay with recursion or a while loop + helper function
i don't see why the latter two would be faster
prisma wave
huh?
old wyvern
That is pretty much checkign with the elapsedTime we used in the earlier loop
oblique heath
i got an error saying "this code is to inneficient" when i first solved it
prisma wave
probably because it timed out
oblique heath
right but why ;-;
prisma wave
idk
oblique heath
all i did was move stuff into a function
and i made it recursive too i guess but blitz literally has what i had originally, just with a function
very weird
prisma wave
recursive solutions are the best anyway
oblique heath
i can't agree more
tranquil crane
If you do another one after that I'll join it, won't be able to for like 10 minutes
prisma wave
alrighty
we probably will
not like any of us have anything better to do
@old wyvern @jovial warren ?
oblique heath
is this supposed to happen
prisma wave
yes
oblique heath
i like it
prisma wave
it's a feature

as long as I get to use Python for anything other than shortest then I'll play lol
oblique heath
fingers crossed it's reverse
prisma wave
python for shortest is cheating
cinder flare
reverse? does that mean you want to take the longest or something lol
jovial warren
no
oblique heath
it means you have to figure out what to do
prisma wave
shall we start?
oblique heath
based on the output
cinder flare
oh isee
prisma wave
unless anyone else is joining
oblique heath
ez pezy
ocean quartz
I join when you finish lmao

okey

Kotlin: Is the only way to loop thru the digits of a number by converting it to a char array?
hot hull
Or just get the size
lunar cypress
no
old wyvern
test
hot hull
And increment index
old wyvern
1234
oblique heath
you can use substring and loop for the length like frosty said ye
old wyvern
@static zealot what is this new avatar
static zealot
do you not like it?

omg parseint doesn't take a char wtf
old wyvern
I cant even tell what that is
lunar cypress
you're looking for Character.digit
old wyvern
The level thing?
oblique heath
@cinder flare char+""

how did I get 4 when I joined at minute 10
because you're last of the people who got 100% lol
old wyvern
I have like 2 weeks to my mid terms now I think

useless language lacks even the most BASIC functions
😮
cinder flare
haskell?
old wyvern
No!
lunar cypress
blasphemy
old wyvern
What was the question btw?
lunar cypress
it was a weird question
old wyvern
Another really long one?
prisma wave
nah
tranquil crane
I spent 90% of the time just trying to understand the question
prisma wave
minimum possible value of subtracting 9 from each digit of n
old wyvern
o.o
lunar cypress
"Create the smallest number from the input by either subtracting each digit from 9 or not"
prisma wave
123 => min [823, 163, 126]
lunar cypress
This or something similar was the way it was phrased
prisma wave
yes
cinder flare
var x = StringBuilder()
N.forEach {
var n = it.toString().toInt()
if (9-n<n) n = 9-n
x.append(n)

that's Blitz' solution

anything wrong with this?

aight
tranquil crane
cinder flare
anything wrong with this?
no I was showing it off as an example of brilliance and how fucking dumb I am lol
cinder flare
it's cause you used C# lmao
tranquil crane
that was BM's

😬
tranquil crane
I used TypeScript lol
cinder flare
ewwww

what was the question this time
old wyvern
reverse the alphabets
oblique heath
o.O
cinder flare
i feel i am doing this very poorly

that's cursed

I'm dumb, I thought 'a' was 65 lol

maths already going great here
tranquil crane
my answer is absolutely cursed

would be nicer with some MONADS

tranquil crane
no magic values here
old wyvern
Monads solve everything
ocean quartz
Share code Nicole
ocean quartz
That's smart
prisma wave
haskell definitely cleanest tho
ocean quartz
Didn't even think about the char code
old wyvern
Throw em onto your torn shoes? Fixed.
Throw em onto your purse? Fixed, more money.
Hotel? Trivago

what in the fuck you can't do indexOf on a char array
oblique heath
can someone send me a link to the clash report
static zealot
what in the fuck you can't do indexOf on a char array
you can
ugh you guys started 2 of them
prisma wave
honestly not even that complicated
oblique heath
aw i cant view the code
tranquil crane
those are both the reports
old wyvern
we need hasklash in here
prisma wave
pretty much identical to python except the lambda
old wyvern
!!!
prisma wave
!!!
lunar cypress
not even waiting for others smh
prisma wave
no this is the same one
old wyvern
Petition to add hasklash
prisma wave
just submit something funny
lunar cypress
I'll be off now anyway, you people have fun

adios
old wyvern
ciao

could be worse
oblique heath
how many fastest have we had in a row now
cinder flare
oop
static zealot
```
map (\x -> chr (ord('z') - ord(x) + ord('a'))) word
```
let me guess. x is looping thru the chars of the word and ord() gets the ascii value of the chars and it does ascii(x) - ascii(char) + ascii(a) and then converts that to a char and maps it?
idk
old wyvern
let me guess. x is looping thru the chars of the word and ord() gets the ascii v...
yes
prisma wave
let me convert
old wyvern
wonderful
cinder flare
I think I just need to become more familiar with stuff
tranquil crane
what does reverse do?
prisma wave
word.map {
('z'.toInt() - it.toInt() + 'a'.toInt()).toChar()
}
reverses the string. finish to start
old wyvern
what does reverse do?
gives you input and output, you need to figure out the question
tranquil crane
I mean the reverse mode lmao
tranquil crane
that sounds painful
static zealot
like 10 options
prisma wave
like reverse engineering
static zealot
and you have to know
what it does
to figure out
what it does
and then code it
prisma wave
oh god
tranquil crane
is that a SNAKE

This one is confusing
oblique heath
this one was a lot easier than i thought when i first saw it
winter iron
mine bugged out on 2nd to last test
winter iron
mhm
cinder flare
wtf yeah what's up with the second to last
static zealot
and now I'm 3rd because of it
oblique heath
check yer casting
winter iron
xXd
cinder flare
my casting?
static zealot
or was that not a requirement?
cinder flare
i did no casting
static zealot
all the tests worked
oblique heath
wait blitz i think you checked the tongue correctly
static zealot
but of course it only gives 71
tranquil crane
just submitted it with my debug lines but who cares
winter iron
@static zealot ur last 2 tests would have failed
oblique heath
^
static zealot
oh really?
oblique heath
gotta cast to int
tranquil crane
go view my debug code if you dare
static zealot
I missed it then
ocean quartz
I'm perpetually 4th place
cinder flare
there's only one snake per line right?
oblique heath
yes
static zealot
yeah
tranquil crane
snek
cinder flare
then wtf is up with the last two
prisma wave
haskell division makes me want to die
ocean quartz
I thought it was the perfect language!
prisma wave
almost perfect
prisma wave
i can see why they did it tbf
tranquil crane
that whole language is a minefield
prisma wave
fromIntegral (length happyCount)
fromIntegral converts an Int to a "Float"
because you can only do truncating division on ints
ocean quartz
Share code
cinder flare
no?
tranquil crane
System.`in` in kotlin is cursed
cinder flare
what would I cast
static zealot
yeah that's what I didn't do either
cinder flare
fun main(args : Array<String>) {
val input = Scanner(System.`in`)
val n = input.nextInt()
if (input.hasNextLine()) {
input.nextLine()
}
var counter = 0
for (i in 0 until n) {
val snake = input.nextLine()
if (snake.startsWith(">-") || snake.endsWith("-<")) {
counter++
}
}
println(((counter / n) * 100).toString() + "%")
}```also for some reason it doesn't let me do println(int + "%")
prisma wave
shame
tranquil crane
you didn't truncate the percentage
cinder flare
yeah you gotta toString it
