I've figured out how to sort depths
(added an Array for them) + set
a variable on mouse click and stop rotating.
Here is my rotating menu for the archives
(one thing I still don't like is that because
the objects on the bottom are scaled down
the angle between them seems too big)
package {
import flash.display.*;
import flash.events.*;
import flash.filters.*;
public class RotMenu extends Sprite {
public static const W:uint = 120;
public static const H:uint = 80;
public static const R:uint = 32;
public static const BLUR:BlurFilter = new BlurFilter(2, 2,
1);
private static const SHADOW:DropShadowFilter = new
DropShadowFilter(8,
80, 0x000000, 0.4, 32, 32, 1, 1, false, false, false);
private static var A:Number;
private static var B:Number;
private static const GR:Number = Math.PI / 180;
private var start:Number = 0;
private var delta:Number = 0;
private var depths:Array;
private static var mouseDown:Boolean;
public function RotMenu(total:uint) {
depths = new Array(total);
delta = Math.min(60, 360 / total);
for (var i:uint = 0; i < total; i++) {
var rect:Sprite = new Sprite();
// do not show the rect before its coordinates
// have been set by handleEnterFrame()
rect.visible = false;
rect.graphics.lineStyle(4, 0x4F69B5);
rect.graphics.drawRoundRect(-W/2, -H/2, W, H,
R);
rect.graphics.lineStyle(2, 0x91BCE5);
rect.graphics.beginFill(0xA3DD8E);
rect.graphics.drawRoundRect(-W/2, -H/2, W, H,
R);
rect.graphics.endFill();
rect.tabIndex = i;
addChild(rect);
depths[i] = rect;
}
addEventListener(Event.ADDED_TO_STAGE, handleAdded);
addEventListener(Event.ENTER_FRAME, handleEnterFrame);
addEventListener(MouseEvent.MOUSE_DOWN,
handleMouseDown);
addEventListener(MouseEvent.MOUSE_UP, handleMouseUp);
addEventListener(MouseEvent.MOUSE_OUT, handleMouseOut);
}
private function handleMouseDown(event:MouseEvent):void {
mouseDown = true;
}
private function handleMouseUp(event:MouseEvent):void {
mouseDown = false;
}
private function handleMouseOut(event:MouseEvent):void {
mouseDown = false;
}
private function handleAdded(event:Event):void {
A = Math.min(x, stage.stageWidth - x) - W/2;
B = Math.min(y, stage.stageHeight - y) - H/2 - 8;
}
private function handleEnterFrame(event:Event):void {
// the starting angle - for the 1st rect
if (! mouseDown)
start += mouseX / 100;
for (var i:uint = 0; i < depths.length; i++) {
var rect:Sprite = depths[i];
var angle:Number = start + delta *
rect.tabIndex;
// scale the rect from (0.70-0.30) to
(0.70+0.30)
rect.scaleX = rect.scaleY = 0.7 +
0.3 * Math.sin(angle * GR);
rect.x = A * Math.cos(angle * GR);
rect.y = -B * Math.sin(angle * GR);
rect.filters = (rect.y > 16 ?
[BLUR, SHADOW] : [SHADOW]);
rect.visible = true;
}
depths.sortOn('y', Array.NUMERIC);
for (var i:uint = 0; i < depths.length; i++) {
var rect:Sprite = depths[i];
setChildIndex(rect, 0);
}
}
}
}
And then in the .fla file:
stop();
var rot:RotMenu = new RotMenu(12);
rot.x = stage.stageWidth / 2;
rot.y = stage.stageHeight / 3;
addChild(rot);
