[fugli] Actionscript function calls

[Phil Gray]

I am just getting back into Flash after a long gap and am interested in 
taking advantage of the new dynamic drawing capabilities of MX.

I have been playing around with some code of Ric Ewing's ( 
http://www.macromedia.com/devnet/mx/flash/articles/adv_draw_methods.html & 
http://actionscript-toolbox.com/flashmx_drawingtools.php ) but I have run 
into what is probably a fundamental misunderstanding of mine when it comes 
to calling functions/MovieClips.

Given the example below, why does only the C80 circle draw and not both 
circles?

MovieClip.prototype.drawCircle = function(r, x, y) {
    this.moveTo(x+r, y);
    a = Math.tan(22.5 * Math.PI/180);
    for (var angle = 45; angle<=360; angle += 45) {
        // endpoint:
        var endx = r*Math.cos(angle*Math.PI/180);
        var endy = r*Math.sin(angle*Math.PI/180);
                // control:
        // (angle-90 is used to give the correct sign)
        var cx =endx + r*a*Math.cos((angle-90)*Math.PI/180);
        var cy =endy + r*a*Math.sin((angle-90)*Math.PI/180);
        this.curveTo(cx+x, cy+y, endx+x, endy+y);
    }
}
        
var c50 = this.createEmptyMovieClip("c", 1);
c50.lineStyle(2, 0x336699, 100);
c50.beginFill(0x6699aa, 100);
c50.drawCircle(50, 200, 200);
c50.endFill();
var c80 = this.createEmptyMovieClip("c", 1);
c80.lineStyle(2, 0x996633, 100);
c80.beginFill(0xaa9966, 100);
c80.drawCircle(80, 10, 10);
c80.endFill();
TIA
