Here’s a simple function to change the color (including alpha) of what have been and what will be drawn.

// set a new color, including alpha, and change the already drawed line
public function changeColor(c:Number,a:Number=1):void {
lineColor = c;
lineAlpha = a;
stroke.graphics.lineStyle(lineWeight, lineColor, lineAlpha, false, “none”, CapsStyle.NONE);

var newColor:ColorTransform = new ColorTransform();
newColor.alphaOffset = a;
newColor.color = c;
stroke.transform.colorTransform = newColor;
}

Andy > Hmm, guess you’re right have the same, but I still have the problem with
for (var i:int in lengthsArray){

???

Thank you for this. This is quite useful! I've needed to draw dotted/dashed lines for a few applications I'm working on. I've also created a couple classes for drawing dotted or dashed circles easily. I figured I'd mention that here in case anyone is looking for it.

Sorry for being slow to reply here…

It looks like an extra “.length” found its way into that line somehow. On line 54 I just have:

for (var i:int in lengthsArray){

Sorry forgot to add that:

DashedLine.as, Line 54
for (var i:int in lengthsArray.length){

Does it tell you where the error occurred? (i.e. the line number) I may have something wrong in there…
