Topic: 20 Liners - August 08 - Space

Looks like I'm responsible for this month's theme and after a few days delay (due to excessive climbing of stairs in churches, arcs of triumph and Eiffel towers), here we go.

Space!

Use your 20 available lines of code to do something awesome relating to space.
Interactive solar systems, procedural exoplanets, space shooters or the good old starfield. It's all good for this month's 20 liner!


The rules:
Use a maximum of 20 lines of (effective) code
Literal object declarations count as one line ( a variable assignment ) except for the body of the methods declared there.
Commas shouldn't be used to execute several instructions on the same line.

As no one chose to use external libraries for July's, I figure we just let the option to use those stand? So, you are free to use any of the following JavaScript libs: Prototype/Scriptaculous, jQuery, Moo, Processing.js.

// WARNING: nonsensical example approaching

            // declare a couple of variables
/* 01 */    var baz = "Fy",
/*  | */        foo =
/*  | */        {
/*  | */            name:"Bob",
/*  | */            kind:"cat",
/*  | */            yield:function( msg )
/*  . */            // the expressions of this function count
/*    */            {
/* 02 */                var msg = msg||"I'm "+ name +" the "+ kind +".";
/* 03 */                alert( "Meow! "+ msg );
/*    */            }
/*  . */            // resume to line 01
/*  | */            isAlive:Math.random()>.5;
/*  | */        },
/*  | */        bar = "it's candy";
            
/*    */    document.body.onclick = function()
/*    */    {
/* 04 */        val= prompt( 'enter a number' );
/* 04 */        for( i=0; i<10; i++ )
/*    */        {
/* 05 */            alert( stupidFunction( val, i ) );
/*    */        }
/*    */    }

            // like regular function, anonymous function declaration do not count
/*    */    (function()
/*    */    {
/* 06 */        setTimeout( arguments.callee, 10 );
/*    */    })
/* 07 */    (); // calling it, however counts as an expression
            
/*    */    function stupidFunction( a, b )
/*    */    {
/* 08 */        return a>b?a:b; // I said it was a stupid function
/*    */    }

Nice theme. I should have time to do a little something.

*bump* Anyone else working on an entry? We can't have just have p01 running off with an easy victory.

Sweep the leg.

I got sacked with work - sounds like a fun topic, looking forward to seeing the entries.

Not sure if it qualifies by that logic a dog turd could be space-related
but... *drumroll* ... here's Fireworks in space

I was working on a space shooter for last month's challenge during the train trip to Helsinki. If I've time I'll try to finalize it.. (though I started my studies at tut few days ago and I've lots of things in my todo list).

Arthurio: Space is huge and largely unexplored. If you say that somewhere there are space fireworks like these, I'll take your word for it.

smoff: Sounds good, looking forward to it.

My entry: Lunar Lander in 5 lines.

I believe, I've bent the rules a little bit too far this time...

It's definitely under 20 lines so who cares ... great job!

p01, smoff: You guys got anything?

Nope sorry
I didn't have a specific idea and got myself carried away trying a new design for my site and fighting IE8b2 until the wee hours.

Side note: last week I bumped a bug about Opera not supporting xhr.overrideMimeType() correctly. Hopefuly the patch is on its way. Dunno if it will make it way down to 9.5x or 9.6

Alright then. Thanks for playing, all.

A fine 2nd place goes to Arthurio for his Fireworks in space

And 1st place, for the very cool and spacey Lunar Lander, goes to kwei.

Nice job to both of you. Kwei, you're up.


@p01: does that mean you can get an "untouched" responseText when that's fixed?

Yes. It should provide an encoded ( will it be URL encoding, string escaping or whatever the server sends I'm not sure yet ) responseText, allowing XHR to load "binary streams" in Opera the same way as in FireFox and Safari. XHR.overMimeType() is of course some sort of hack meanwhile XHR2 and the responseBody get, widely, implemented. So when this patch lands, your ID3 and EXIF stuffs should finally work in Opera.

Kudos people. Kwei your lunar lander was a bit on the edge but well under 20 lines, and pretty cool. Arthurio, nice fireworks. At times they form some fractal-y patterns.

Hoorai
I promise that next time, I'll write more compact code and stay farther away from "the edge"! So, everyone ready for next round?

wow - I'm glad I didn't code anything as I was thinking of a lunar lander too having participated a bit in the Google Lunar X-Prize program. Nice work!

Wow, that Lunar Lander game was pretty cool! Nice work!
