Messy Code

var xp:Number=0,yp:Number=0;
var r:Number=0,t:Number=0;
var speed:Number=.01;
var scale:Number=10;
var shape:Shape = Shape(addChild(new Shape()));
shape.x=stage.stageWidth/2;
shape.y=stage.stageHeight/2;
shape.graphics.lineStyle(0,0x000000);

var s:Number=100;
var range:Number=.2;
var b:Number=20;
var a:Number =b*range;

addEventListener(Event.ENTER_FRAME, onLoop);
function onLoop(evt:Event):void {
	range=.2;
	b=20;
	a=b*range;
	t=0;
	shape.graphics.clear();
	shape.graphics.lineStyle(0,0);
	for (var i:int = 0; i<6000; i++) {
		var sin:Number=Math.cos(t*int(mouseY/20));
		r =  Math.sqrt(40 * b * (b - a * (Math.pow(sin, int(mouseX/20)))));
		xp=r*Math.cos(t);
		yp=r*Math.sin(t);

		if (t==0) {
			shape.graphics.lineStyle(0, 0);
			shape.graphics.moveTo(xp, yp);
		} else {
			shape.graphics.lineTo(xp, yp);
		}
		t+=speed;
		if (t > (2 * Math.PI + speed)) {
			range+=.3;
			a=b*range;
			t=0;
		}
	}
}

This is an example of raw messy code that draws some interesting shapes. I was waiting somewhere with my laptop a few weeks back and I wrote this and e-mailed this to myself – it’s completely unoptimized and unedited.

I was working on documentation for QuickBox2D today but didn’t finish it – so I posted this instead. I hope to finish the docs for tomorrow…
