Steven sacks just posted custom class that creates an Apple style preloader. It’s a simple class that uses the Flash Drawing API which makes it light and efficient. Check it out below.

import flash.events.TimerEvent;
import flash.display.Sprite;
import flash.display.Shape;
import flash.utils.Timer;
public class CircleSlicePreloader extends Sprite
{
private var timer:Timer = new Timer(65);
private static const SLICE_COUNT:int = 12;
private static const RADIUS:int = 6;
public function CircleSlicePreloader()
{
super();
draw();
timer.addEventListener(TimerEvent.TIMER, onTimer, false, 0, true);
timer.start();
}
private function onTimer(event:TimerEvent):void
{
rotation = (rotation + (360 / SLICE_COUNT)) % 360;
}
private function draw():void
{
var i:int = SLICE_COUNT;
var degrees:int = 360 / SLICE_COUNT;
while (i--)
{
var slice:Shape = getSlice();
slice.alpha = Math.max(0.2, 1 - (0.1 * i));
var radianAngle:Number = (degrees * i) * Math.PI / 180;
slice.rotation = -degrees * i;
slice.x = Math.sin(radianAngle) * RADIUS;
slice.y = Math.cos(radianAngle) * RADIUS;
addChild(slice);
}
}
private function getSlice():Shape
{
var slice:Shape = new Shape();
slice.graphics.beginFill(0x666666);
slice.graphics.drawRoundRect(-1, 0, 2, 6, 12, 12);
slice.graphics.endFill();
return slice;
}
}
}
}
