beaded curtain

[gilc]

hi every one,
i am making curtain beads( beads curtian) and i want the beads of the curtain to sway a bit, like a light wind displaces them, now, i want to know how can i do it , i tried several ways, but all are not perfect or close to it , and they require a guide layer ans many guided layers, (one layer for one bead ), is there a better way ,,
thank u

You could do it with actionscript. Each bead would be a movie clip which has its position altered by a slight amount every frame (script is below), you could then use the drawing API to draw lines which connect the beads together.

MovieClip.prototype.drawCircle = function(x, y, r, col) {
	var endX, endY, controlX, controlY;
	arcs = 8;
	var arcAngle = (360/arcs)/180*Math.PI;
	var controlDist = r/Math.cos(arcAngle/2);
	this.moveTo(x+r, y);
	this.lineStyle(2, col);
	this.beginFill(col, 50);
	for (var i = 1; i<=arcs; i++) {
		endX = x+r*Math.cos(i*arcAngle);
		endY = y-r*Math.sin(i*arcAngle);
		controlX = x+controlDist*Math.cos(i*arcAngle-arcAngle/2);
		controlY = y-controlDist*Math.sin(i*arcAngle-arcAngle/2);
		this.curveTo(controlX, controlY, endX, endY);
	}
	this.endFill();
};
//
centre = 275;
waveSpeed = .1;
waveMax = centre+15;
waveMin = centre-15;
//
for (var i = 0; i<4; i++) {
	this.createEmptyMovieClip('bead'+i, i);
	this['bead'+i].drawCircle(centre, i*40, 15, 0xCC0000);
}
//
this.onEnterFrame = function() {
	waveSpeed *= (waveX>waveMax || waveX<waveMin) ? -1 : 1;
	for (var i = 0; i<4; i++) {
		this['bead'+i]._x += waveSpeed*i*i;
	}
	waveX = centre+this['bead3']._x;
};
