Challenge idea: Chip's Challenge Koth.

Chip is a bot, programmed by the challenged, and has to reach the end of the level as fast as possible, in terms of turns.

There will probably be only a subset of the game's objects.

wizzwizz4

How does one go about writing a KOTH controller?

zyabin101

idk

zyabin101

About the subset of the game's objects:

Obviously yes: walls, keys, doors, chips, and a locked end room with a socket for the entrance and the magic hole to end the level in that end room.

@TùxCräftîñg Why did you edit an off-topic question?

zyabin101

6:05 PM

Oh, and also blocks.

TùxCräftîñg

because i hate seeing code not in code blocks :P

@TùxCräftîñg I was so tempted to do that, but forced myself not to. Thanks for doing it, although speaking as a moderator I'm not sure it was a good idea.

Especially since that'll probably put it in the reopen queue

I voted "needs a winning criterion"

But maybe "unclear" is a better choice

zyabin101

I voted "unclear", as the challenge spec first, then winning/validity criteria.

I chose unclear

the two close reasons are valid

Come on guys. It's clearly intended to be a code-golf, and it's a brand new user. Not a single comment before closing it?

Fiat Tipo

The Fiat Tipo (Type 160) is a small family car, designed by the I.DE.A Institute design house, and produced by the Italian manufacturer Fiat between 1988 and 1995. The Tipo was initially available only as a five-door hatchback. The car was made entirely out of galvanized body panels to avoid rust, and was built on a completely new Fiat platform, which was later used on Fiat, Alfa-Romeo, and Lancia models. It also stood out because of its boxy styling that gave it innovative levels of packaging, rear passenger room being greater than that in a rear-wheel-drive Ford Sierra, but in a car that was...

Beta Decay

I feel really guilty now :P

Dennis

@quartata Well, HTML 5 is almost 2 years old... <datalist> would have been perfect for TIO. Now I have to roll my own. Thanks a lot, Apple.

quartata

I think there's a workaround

A: HTML5 datalist tag is not populating in Safari

HTML5 datalist workaround for Safari and/or older browsers You can use a select element inside the datalist, and duplicate the option tag values as readable text in these. For example: <!DOCTYPE html> <html> <head> <title>test</title> <style> input[list="languages"] { width: 12em;...

DJMcMayhem

@BetaDecay judge it on it's own merit. Is it clear?

quartata

^^ I remember doing this for something a while back

betseg

6:51 PM

who uses safari anyways?

quartata

Most mobile users?

betseg

im ignoring the most part, but true :/

DJMcMayhem

I use Chrome on mobile

TùxCräftîñg

i use FF on mobile

Beta Decay

@DJMcMayhem Well I'm not completely clear on what it's about, but it might probably be clear to a mathematically inclined person

betseg

6:53 PM

@DJMcMayhem saem

Beta Decay

I use Chrome for Android aussi

Dennis

@quartata Not sure about most (at least here, Android is by far more common than iOS), but still enough to need a workaround for TIO.

@quartata Yeah, just found that myself. I wish I had a way to see how it looks on Safari though.

TùxCräftîñg

example html for my new js library i am developing:

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8" />
        <script type="application/javascript" src="dialpha.js"></script>
        <title>Hello</title>
    </head>
    <body>
        <script type="dialpha/dialpha-asm">
            push8 0
            "Hello, World!"
            call print
            flush
            halt
            :print
            dup
            jiz print.end
            putc
            jump print
            :print.end
            ret
        </script>

DJMcMayhem

@BetaDecay it's not really mathy though. The two problems I see are 1) "moving * that rotates clockwise around the corners, starting from the top left." Is unclear and 2) one of the test cases is 3x4, not 4x4.

Beta Decay

@DJMcMayhem It isn't? Oh, I see

quartata

6:55 PM

@Dennis I can take a picture of it on mobile Safari if you give me a page

not right now though

Beta Decay

FYI, is posting multiple lines of code in chat acceptable? I, personally, find it extremely annoying (not just you Tux, but you reminded me)

Dennis

Haven't implemented it yet. Seeing how the language selection is a rather important part of TIO, I guess I'll just roll my own.

I didn't think I'd ever come by a feature in the HTML spec that works on IE but not on Safari...
