Hope this helps someone.

To redraw if the w changes, i did two things:
1. i added the variables on top of the class:

private var tile:BitmapData;
private var r1:Rectangle;
private var r2:Rectangle;

2. i added a light weight redraw function (tile, r1, r2 have all ready been created):

private function redrawDottedLine():void{
graphics.clear();
graphics.beginBitmapFill(tile, null, true);
graphics.drawRect(0, 0, _w, _h);
graphics.endFill();
}

For Flex-User, u can also extend the class by SpriteVisualElement instead of Shape:

public class DottedLine extends SpriteVisualElement {…}

So u dont have to wrap anything. But Shape of course has better performance?!

Awesome class and thanks for sharing. I’m sure others will find it useful.

I wanted to mention it because I’ve definitely found the need for drawing straight dotted/dashed lines. But it’s quite difficult to draw circles using this method!!

So, I hope it’s useful for you all.
