BlindKing: Hello, does anyone on here feel like explaining how I can use trig to solve Mars Lander 2?
BlindKing: in Java.
MadKnight: why not, Automaton2000 ?
Automaton2000: i still have a chance to play against me
Denshire: ugh trying to make a basic algorithm and then finding out you need trigonometry:triumph: what is an arccosine anyway
MadKnight: Denshire which game are u playing ?
Denshire: code v zombies
MadKnight: and what kind of trigonometry? what exactly ?
Denshire: trying to think of something original, with danger levels and all
Denshire: just trying to figure out the location the player will be in after making a move towards a human
Denshire: i honestly don't know how
Denshire: trig might be the only answer
Denshire: i'm trying to make a triangle, with the actual movement as hypotenuse, then find an angle and use that to find the x and y
Denshire: is this even a good idea? i might have ignored everything related to trig in highschool
MadKnight: u need to take vector from player to target, divide it by its length, and then multiply by player's speed
Denshire: oh
Denshire: thanks for the tip
Denshire: (might have also ignored everything related to vectors in highschool but the internet will help me)
MadKnight: they're pretty simple
Denshire: yeah, i know, but it's 11pm and my brain can't handle it
Denshire: i'll probably come back to this tomorrow
Denshire: but what would be the speed exactly? just the distance moved every turn?
Denshire: oh
Denshire: wait
Denshire: i just read what you wrote again and now i actually understand everything
Denshire: it's more simple than I thought at first
Denshire: well, thanks a lot, actually! But i'm still gonna try and restore my nonexistent sleep schedule first
MadKnight: okay cya
Denshire: g'night:sleepy:
AnsarDauletbayev: Hello everybody, have some cod of this https://www.codingame.com/ide/puzzle/aneo . I can t understand and can t find it in google. Thank you
wenyue: ?
AnsarDauletbayev: i just start to learn python and can t understand how to make cod for this
MadKnight: code* AnsarDauletbayev
AnsarDauletbayev: ok sorry) my english is not good =)
wenyue: Chinese?
RuiY: Yes, hands up! I'm new here, hello
MadKnight: no he's not, wenyue
HardikPoudel: anyone plays fall guys?
HardikPoudel: ive no teammates
MadKnight: don't they have discord HardikPoudel ?
jacek: you seem so active lately
MadKnight: because i'm back
MadKnight: shouldn't i be, jacek ?
jacek: lets ask Automaton2000
Automaton2000: i would not be a good idea
DaNinja: :grin:
sugam: bruh anybody recently added from islington?
jacek: ?
Astrobytes: I think he's referring to the university that the guy who's doing the unofficial contest goes to
sugam: I could not solve the simplest problem lol it's taking time to get used to
uvBoss: just do a few puzzles u will get used to it
uvBoss: @sugam
sugam: what are the prerequisites to start doing AI challenges?
uvBoss: u can start using if statements
uvBoss: and slowly work your way towards algorithms
uvBoss: if its your first time
sugam: yes my first time on this site
uvBoss: i started with if statements and then somehow i transitioned to algorithms
uvBoss: xD
sugam: how to debug
uvBoss: which lang?
sugam: java
uvBoss: To debug: System.err.println("Debug messages...");
sugam: debug the logical errors
uvBoss: wdym?
uvBoss: just print out variables using the above method
sugam: yeah, I found out that I can actually print on the console and test my code
uvBoss: yea
sugam: how to get codin point
UndisclosedBeastAndHisDog_820d: hi guys
Uljahn: sugam: play games in Compete section
sugam: thanks Uljahn
Zenoscave: Did they remove the level 3 req for chat?
sugam: I'm level 5 btw
Zenoscave: no, not you, sorry! the UndisclosedBeastAndHisDog_820d
Zenoscave: is level 1
Uljahn: maybe through external client
Zenoscave: makes sense. can't really stop jabber
sugam: wow you guys are pro damn.
Zenoscave: why do you think that? I'm not really pro...
Uljahn: im not even a coder
Zenoscave: yeah you're a cat.
Zenoscave: right Uljahn
Uljahn: pewpew
Zenoscave: pewpew
Uljahn: i mean yes
Zenoscave: I understood
sugam: ranking 43rd
Zenoscave: ranking is a bad metric. doesn't really tell much beyond like the top 15-20
Zenoscave: there is such a large gap
sugam: I'm just getting started
Zenoscave: well keep with it! :)
sugam: It is starting to look less intimidating
sugam: can i follow you two?
Uljahn: sure
Zenoscave: go for it
sugam: thanks
Uljahn: there is no need to be intimidated, you can code for fun and learn things at your own pace, solve puzzles and look through others' solutions or play multiplayers and aim for top-1k, then top-500 etc.
sugam: Actually our college is having some kind of competition or something and they asked me to join in this site. ngl I'm starting to like it.
uvBoss: have you joined the discord?
sugam: yes
uvBoss: kk
Collector_Nishant: is someone from this clash online to hear me
rivancic: Hello. I am about to leave but I want to return and continue. Is there a way to save the code in Coders Strike Back?
rivancic: Or you have to copy paste it and store somewhere locally?
MadKnight: it saves when u play
Uljahn: click play or submit
wenyue: :grinning:
wenyue: :grinning:
wenyue:
I think it's so difficult here
wenyue:
My foundation is too bad
w-kosse: Hi! Bit new, is there a way to measure performance of one solution vs another?
reCurse: Use a high resolution timer
Hjax: if you mean in a multi, theres brutaltester
w-kosse: more like general things, execution times, cpu & memory use etc
w-kosse: but coding someting in myself is probably a good way to go as well
Hjax: ah then i defer to recurse's answer
w-kosse: i'll look into it, thnx!
Hjax: i would say that execution speed is almost never a concern when you are starting out
Hjax: if you are running out of time its much more likely that you have an infinite loop or some bug
w-kosse: haha it's not a concern, just a curiosity, what route would work better
Hjax: do some puzzles, when you get comfortable enough with the site maybe try a multi that looks fun
w-kosse: will do, looks fun so far! thnx for the input :smiley:
sunksuperset370: 'elo
HexObEe: hello
Gloryness: Hi
HexObEe: Just discovered this website today.
HexObEe: Wow. Wish i had found it sooner
Gloryness: I've only been using it for 2 days but I've known it for ages
HexObEe: :grinning:
HexObEe: So far seems like a great place for practice (and for fun)
Hjax: its a lot of fun
Hjax: especially contests
sunksuperset370: 'elo
DinuBrat: HI
Gloryness: everyone on my clash got 0% because of this glitch
PlungeDominick: I think it was just a bad clash :(
DinuBrat: @Ru
Hjax: you already said that
Hjax: oh scroll
Hjax: the chat box needs a "new messages below" box
sunksuperset370: i think i might need help here
Hjax: whats up
sunksuperset370: i am in fast mode
sunksuperset370: here me code
sunksuperset370: http://chat.codingame.com/pastebin/8dee019a-8089-461e-a24b-53909710854c
sunksuperset370: :sweat_smile:
Hjax: im not sure what you are going for there
sunksuperset370: ?
Hjax: i dont know what that code is supposed to do
sunksuperset370: what i am going for right now is that i am trying to look for S
Hjax: it looks like it returns 1 if S isnt the empty string, and prints 0 otherwise
sunksuperset370: then i am creating a while loop until there is no more S
Hjax: your loop doesnt change S though
Hjax: and why is there a return statement in there
PlungeDominick: s is given
Hjax: yes, but you want to loop through S i assume
Hjax: which means you probably want to change S each iteration
Hjax: otherwise you just loop forever
sunksuperset370: oh wait right i forgot
sunksuperset370: i needed to subtract s by one too
sunksuperset370: thx
PlungeDominick: Damn true I wasn't even reading it properly
sunksuperset370: http://chat.codingame.com/pastebin/f173c40a-954e-4a56-9705-a7e35c70718d
sunksuperset370: this don't work either
PlungeDominick: I was trying to figure out this reverse
sunksuperset370: time out
sunksuperset370: ed
Hjax: why is there a return statement in your loop
sunksuperset370: so i can extract the i from the loop to log it
Hjax: thats.... not how that works
sunksuperset370: ooooookkkkkkk
sunksuperset370: would you like to help
Hjax: i is already available outside of your loop
Hjax: you dont need to do anything special
sunksuperset370: but the return shouldn't do anything
sunksuperset370: than
Hjax: the return quits out of your main method so you never reach the console log
sunksuperset370: so that is the reason i wan't getting an answer
sunksuperset370: right?
Hjax: thats a reason, i still dont know what this code does, i dont think it does what you want it to do
sunksuperset370: ok
sunksuperset370: i mean it has been a long time since i was last on the site
sunksuperset370: or coding
w-kosse: i is already in your scope, your loop doesn't need to return it, just set it, returning it will quit the loop
sunksuperset370: ok
sunksuperset370: i am in a shortest mode now and i want to know how this works
sunksuperset370: i don't know anything about binary
sunksuperset370: the example given is 15 => 1111 and the output will be 4
sunksuperset370: 'ello??
Hjax: so whats the goal? count the number of 1s in the binary representation?
sunksuperset370: yes
sunksuperset370: input 15 output 4
sunksuperset370: that is the example
sunksuperset370: 10 mins left
Hjax: i cant give you the answer, thats cheating :P i can just answer general questions
sunksuperset370: nono
sunksuperset370: nonono
sunksuperset370: i am not asking for the answer
sunksuperset370: i am asking how does binary work
sunksuperset370: how to convert a number to binary
HexObEe: Hint: you can experiment with the input number given. 1+2+4+8 are the values for binary 1111
sunksuperset370: i think i might get it
Hjax: yeah binary is just base 2, so each place in the number is a power of 2
HexObEe: yeah
Hjax: 1 is 1, 2 is 10, 3 is 11, four is 100, five is 101
Hjax: etc
sunksuperset370: actually i think you are mutiplying by 2 there
sunksuperset370: ?
sunksuperset370: ??????????
Hjax: yes that is how powers of 2 work
sunksuperset370: hjax i don't get it
HexObEe: :D
sunksuperset370: 2 *2 is 4
sunksuperset370: not 10
Hjax: 2 in decimal is 10 in binary
Hjax: 1 * 2^1 + 0 * 2^0 = 2
sunksuperset370: 2 in decimal?
sunksuperset370: sorry got to go
sunksuperset370: bye
HexObEe: yup
Astrobytes: that went well
Hjax: i tried
Astrobytes: :D
HexObEe: problem left hanging :D
Hjax: explaining a new concept just by typing is hard lol
Hjax: maybe i should have told him to google it
Astrobytes: Yeah, usually easier tbh
HexObEe: googling should be your first go-to
w-kosse: well you did a pretty good job either way, haha
Astrobytes: then they should ask questions after
Astrobytes: and yeah, admirable effort :)
Hjax: were you lurking that whole time astro
Astrobytes: Something tells me he wasn't gonna get it regardless
Astrobytes: And yeah :P
Hjax: :P
Hjax: btw are you going to play the unofficial contest?
Astrobytes: I signed up, so hopefully yeah (depending on time + what it is)
Hjax: yay :D
Hjax: contests are great motivation for me to play a multi
Astrobytes: Even if I don't like it I'll probably try to do something at least
Astrobytes: Yeah, it does motivate you somewhat
Hjax: i did pretty well in the last unofficial one
Astrobytes: I remember :)
Hjax: has Nerchio been around recently? i wonder if he will play again
Astrobytes: Was wondering about him the other day, I haven't seen him
sunksuperset370: ok me back
sunksuperset370: sorry i am in school
Astrobytes: Then again, I've been absent a lot recently
Hjax: maybe focus on your classes sunksuperset370 ;)
Astrobytes: Especially if it's mathematics ;)
sunksuperset370: i was free before
sunksuperset370: now i am in mathematics
sunksuperset370: right now
sunksuperset370: i am going to work now
sunksuperset370: bellwork
Astrobytes: Pay attention and get good!
sunksuperset370: nono
sunksuperset370: i am good at math
sunksuperset370: just not coding
HexObEe: cries in calculus
Astrobytes: Counting in binary is math
sunksuperset370: bye
sunksuperset370: for 5 mins
sunksuperset370: hulo me back
sunksuperset370: ok that was not 5 mins sorry
sunksuperset370: but me done with bellwork
sunksuperset370: 'ello????????????????????????
sunksuperset370: :disappointed:
sunksuperset370: :confused:
Astrobytes: OK, 1 more thing to work on: patience ;)
sunksuperset370: i AAMMM LOOONNNNEEELLYYY
sunksuperset370: oh sorry
sunksuperset370: i was feeling lonely
sunksuperset370: so now what i do
sunksuperset370: ?
Astrobytes: You tell me
sunksuperset370: i need to know how binary work
Astrobytes: Google it :)
sunksuperset370: i was about to say i don't go for google as a source
Astrobytes: It's fun to learn, I promise
sunksuperset370: wait wait
sunksuperset370: i need to listen to the teacher or i will get in trouble
sunksuperset370: i know it is but google is not really the best of the sources
sunksuperset370: it gives us links but not the answer
HexObEe: follow the links
Astrobytes: Use your common sense
sunksuperset370: i know but i like to learn from actual people aswering the question
HexObEe: google is just a framework for you to use
sunksuperset370: ?
PlungeDominick: I'm crying, I sat there for like 6 minutes wondering how he had 5 less characters than realized how I could save like 15 with only a minute left
PlungeDominick: then
Krantt: When are the rankings updated?
eulerscheZahl: in about 8 hours if you are referring to the global leaderboard
Krantt: Oki ty
INJECTOR_PRO: join the clash asap
Astrobytes: I shall not.
jacek: ask Automaton2000
Automaton2000: i guess i should try to have a big impact
Logiman09: Hi
Zm4j: Hi
Logiman09: Is it bad that Clash of code is hard for me..?
Zm4j: nah
Astrobytes: You can always do more puzzles instead
Logiman09: @Astrobytes I just cant code
Astrobytes: CG isn't the best place if you're just starting out in all honesty
Logiman09: I've started a little bit but like it's hard for me...I can't understand it...
Astrobytes: As in, you need to know the basics first, CG won't teach you
itzblinkzy: go to freecodecamp or soemthing
itzblinkzy: and then when you know the basics and all that you can come back
itzblinkzy: and maybe you'll be able to do a decent amount of the clashes
itzblinkzy: but they are still very hard
Astrobytes: Or try both side-by-side, depends on your learning style
Astrobytes: And I would recommend starting with easy puzzles over clashes, to begin with
Logiman09: mk... TY
Logiman09: :grinning:
jacek: any idea what game will be in the minicontest?
JBM: tvc
jacek: i doubt it
jacek: no fow
JBM: damn
JBM: hey i can minicontest i i want to
JBM: was thinking of first week of oct
jacek: with blackjack and hookers
JBM: with t-shirts
jacek: tvc t-shirts?
JBM: yup
JBM: i already designed the rest of the paraphernalia
JBM: just got the t-shirts left
Astrobytes: naked troll t-shirts!
JBM: naaaaw
JBM: naked troll is just the briefs
JBM: mmm dunno how to share pix from there
Astrobytes: Removable velcro pants
JBM: just a sec
JBM: oh, imgur doesn't want me anymore
JBM: what's left
Astrobytes: donno, I always use imgur
jacek: imageshack.us
JBM: that still exists
jacek: lets find out
Zm4j: how can i fix problem, if my test cases are green, but submit ones fail, and i cant see those cases
JBM: https://cg.desast.re/tvc/man-front.jpeg https://cg.desast.re/tvc/woman-back.jpeg https://cg.desast.re/tvc/facemask.jpeg
Astrobytes: :rofl:
JBM: inspired by some suggestion on #Fr
Astrobytes: Utterly brilliant
JBM: so that's 3rd prize
Astrobytes: Zm4j - if it's a puzzle you can do custom testcases. The validators are different from the testcases
JBM: 1st and 2nd regular t-shirts (that actually say "winner " and "runner-up" if i manage to)
JBM: facemasks if people want to support the operation and create more t-shirts to give out to language winners
Astrobytes: TvC Inc.
JBM: lol
Hjax: i wonder if they will pick a community multi
Hjax: thats the real way to get one basically no one has played
JBM: or pick one who'll get out just then O:-)
Hjax: the last unofficial contest had a most improved leaderboard
eulerscheZahl: or launch your own alternative unofficial contest if you don't like the choice
JBM: yeah tell me about it
Hjax: lol
JBM: like, seriously, tell me about it
JBM: why did he need a separte leaderboard
JBM: what's wrong with cg's?
JBM: do i need to make one too?
Hjax: ? it was good
JBM: i'm not debating that
JBM: i'm more in "what's the point" territory
Hjax: fun!
JBM: ok
JBM: so i need one too
Hjax: makes the contest feel more real
Hjax: because you can see a leaderboard of just people playing the contest
Astrobytes: It was to account for existing players in the multi, so he had a most improved placement metric to try and keep the competitive aspect alive
Hjax: yeah, otherwise recurs e could have just typed his name into the form, logged off for the entirely of the contest, and still won
Hjax: which isnt very exciting
jacek: so the game should be uttt
Hjax: im hoping its fantastic bits
Hjax: that one looks fun
eulerscheZahl: https://challenges.reply.com/tamtamy/challenges/category/cybersecurity
that one looks interesting to me
Scarfield: there is going to be an unofficial contest?
Astrobytes: nice, my CTF skills are sadly lacking :/
Astrobytes: Oh hey EcksDee
Astrobytes: :P
Astrobytes: And yes
JBM: i've heard about those ctf contests
JBM: and still can't figure out from the outside what it's all about
Astrobytes: Capturing flags :P
Scarfield: lol
Scarfield: and hey, where do i sign up for it? :)
Astrobytes: https://hs-emina.github.io/autumnai.github.io/
Astrobytes: https://discord.gg/PpYr7p3
JBM: so, quake?
Astrobytes: JBM: capturing 'flags' via various cybersecurity-related methods
Shakerica: Oh..God...I feel so nubish I'm the only one ?
Astrobytes: (in brief)
JBM: you're giving me the same impenetrable outside description as tge rest
JBM: yes, capture flags, yes, security, but no general understanding at all
RoboStac: it's basically a hacking competition and when you hack the system you get a 'flag' to prove you've done it
JBM: so the flag is given to all who do?
RoboStac: depends on the contest
Astrobytes: You might have to penetrate a server, hunt down some file, to get access to somewhere else, find info hidden steganographically or something etc etc
JBM: sounds like "not-CTF" at all
RoboStac: yeah, it's not really ctf in any way
JBM: don't get me wrong, sounds like fun
JBM: but that's not AT ALL what i picture as ctf
RoboStac: at least in the gaming sense
Astrobytes: The 'flags' are just goals really
Astrobytes: Yeah I mean it's not exactly Counterstrike
JBM: or just plain old quakemod-ctf
RoboStac: I think it comes from more organised versions where you'd have two teams and they'd both be trying to hack each other
Astrobytes: ^
JBM: i heard about something like that too
JBM: (just not (that i recall) limited to 2)
RoboStac: but now it's just a general hacking contest
JBM: haclking as in penetration?
Astrobytes: Yeah it's kind of blown up into all sorts of themes and categories these days
RoboStac: can be exploiting services, reverse engineering binaries, breaking crypto etc
Astrobytes: JBM: https://challenges.reply.com/tamtamy/challenges/category/cybersecurity#technicalfaq
JBM: yea hcould really be fun
JBM: i enjoyed the overthewire series a lot
JBM: i suppose there's similarities
Astrobytes: Yes, absolutely
Astrobytes: Anyways, I'm out for tonight. Take care all
JBM: gn8
JBM: wait, that doesn't work in en
JBM: just gn then
Astrobytes: :D
Astrobytes: I still get it
JBM: ^^
JBM: note to self: find a more peculiar way of wishing a good night
jacek: let the Luna visit your dreams
JBM: who's that
jacek: the Princess of lucid dreaming
JBM: lost.
JBM: oh mlp?
JBM: took more than the first page of binging
jacek: should do banging instead
JBM: let's try it
JBM: mmm it won't let me websearch
AntiSquid: what tv show are you talking about?
JBM: sorry, fresh out of jokes
jacek: your small horse
Uljahn: unity is sorcery
JBM: discord is?
Amadrobus: First time here, so basically, this site teach you how to create code that is un-maintainable ?
JBM: no, you'll have to exercise that on your own
Amadrobus: Not easily read, basically, when you work for a company, your code act as a chain ?
Amadrobus:
Sorry, but if company use this site for interview, like I am about to do, it kind of set the expectations.
JBM: yeah it's kind of separate
JBM: but not quite
Amadrobus: The only thing I saw is people spending 7-8 minutes, writing a line, that is clever to solve a simple problem.
But it is understandable with about the same amount of brain power that was used to create that line, but in a professional context, when you got 20 of those lines, it become a major barrier of entry for anyone who is newly onboarded in that company.
JBM: you saw people here code?
Amadrobus: I did some clash, you can see the result.
JBM: no thank you
JBM: clashing is...
JBM: i wish i could say "really not what the cg tests are all about"
JBM: but they're really not different enough
JBM: just consider clashes are live competitions
JBM: whereas tests are kind of live, but not too competitive
Amadrobus: It fine to showoff, it can collapse a company when the programer leave.
JBM: i have a slightly different view
JBM: then again i'm not sure if you're talking gamified interviews or clashes
Schwase: classic puzzles are an art and the bots are really impressive
Laminator: I had an interview today where I was able to talk about my clash of codes ranking as one of my projects. Thanks everyone for making this possible by mostly losing to me
Schwase: good save
Schwase: i thought i was gonna have to jump into a private clash against you haha
Schwase: that would be kind of fun actually
Schwase: as long as there is no code golf
Laminator: haha ya I'll have a better chance with code golf. I'm not saying I'm not the best by any means. But I think I've done good enough to discuss it during an interview.
Laminator: too many nots****
Schwase: thats good!
Schwase: was just joking around too haha
Schwase: you do know that CG uses bots to fill up clash lobbies right?
Laminator: Yeah, I figured the same weird profiles that left half the time were bots lol
Schwase: all are level 7
Laminator: I guess I should be thanking them separately
Schwase: just an easy way to figure it out
Schwase: dude that french one matthieu is actually nuts
Schwase: his fastest times are insane clips
Schwase: usually beats me out by seconds
Schwase: but im always amazed by it
Laminator: I don't think I've ever lose to one unless I couldn't solve the problem
Schwase: yikes
Schwase: i dont know what i missed in that one
Laminator: FR. 100% on test cases. You can bet I submitted a review.
Schwase: someone did score 100%
MadKnight: is 100% even possible, Automaton2000 ?
Automaton2000: it's hard to find a way to save your code and i'll be happy with the result
Justin123: I got 100 but honestly I think my code was wrong
Laminator: I second that thought
Laminator: hahaha jkjk
