A Function in Flash 8 help file should be changed

Question

At curveTo Function,there is an example how to create a
circle by ActionScript:
quote:
this.createEmptyMovieClip("circle2_mc", 2);
circle2_mc.lineStyle(0, 0x000000);
drawCircle(circle2_mc, 100, 100, 100);
function drawCircle(mc:MovieClip, x:Number, y:Number,
r:Number):Void {
mc.moveTo(x+r, y);
mc.curveTo(r+x, Math.tan(Math.PI/8)*r+y,
Math.sin(Math.PI/4)*r+x, Math.sin(Math.PI/4)*r+y);
mc.curveTo(Math.tan(Math.PI/8)*r+x, r+y, x, r+y);
mc.curveTo(-Math.tan(Math.PI/8)*r+x, r+y,
-Math.sin(Math.PI/4)*r+x, Math.sin(Math.PI/4)*r+y);
mc.curveTo(-r+x, Math.tan(Math.PI/8)*r+y, -r+x, y);
mc.curveTo(-r+x, -Math.tan(Math.PI/8)*r+y,
-Math.sin(Math.PI/4)*r+x, -Math.sin(Math.PI/4)*r+y);
mc.curveTo(-Math.tan(Math.PI/8)*r+x, -r+y, x, -r+y);
mc.curveTo(Math.tan(Math.PI/8)*r+x, -r+y,
Math.sin(Math.PI/4)*r+x, -Math.sin(Math.PI/4)*r+y);
mc.curveTo(r+x, -Math.tan(Math.PI/8)*r+y, r+x, y);
should be changed:
this.createEmptyMovieClip("circle2_mc", 2);
circle2_mc.lineStyle(0, 0x000000);
drawCircle(circle2_mc, 100, 100, 100);
function drawCircle(mc:MovieClip, x:Number, y:Number,
r:Number):Void {
mc.moveTo(x+r, y);
mc.curveTo(r+x, Math.tan(Math.PI/8)*r+y, Math.
cos(Math.PI/4)*r+x,
Math.sin(Math.PI/4)*r+y);
mc.curveTo(Math.tan(Math.PI/8)*r+x, r+y, x, r+y);
mc.curveTo(-Math.tan(Math.PI/8)*r+x, r+y, -Math.
cos(Math.PI/4)*r+x,
Math.sin(Math.PI/4)*r+y);
mc.curveTo(-r+x, Math.tan(Math.PI/8)*r+y, -r+x, y);
mc.curveTo(-r+x, -Math.tan(Math.PI/8)*r+y, -Math.
cos(Math.PI/4)*r+x,
-Math.sin(Math.PI/4)*r+y);
mc.curveTo(-Math.tan(Math.PI/8)*r+x, -r+y, x, -r+y);
mc.curveTo(Math.tan(Math.PI/8)*r+x, -r+y, Math.
cos(Math.PI/4)*r+x,
-Math.sin(Math.PI/4)*r+y);
mc.curveTo(r+x, -Math.tan(Math.PI/8)*r+y, r+x, y);

This is a popular one. ;)

For better or worse, though, that's the way to do it.

ActionScript doesn't support something like a global delay()
or sleep()
function. In ActionScript 2.0 (or AS1) you can use
setInterval() or
setTimeout() to delay as many functions as you please. In
ActionScript
3.0 -- for which you'd need Flash CS3 -- you can use the
Timer class.
