Change stroke width with AS3?

[tdriley]

So, I have a movie clip which consists of a filled vector circle with a stroke. Is it possible to increase/decrease the stroke to a specific thickness in pixels with actionscript whilst the swf is playing?

Thanks

If you draw a circle dynamically using graphics API then its possible to chage the stroke by using lineStyle method.

But if that circle has already been drawn and placed in the stage, I don't think you can change it's stroke.

Can I ask, why don't you draw it dynamically using actionscript. It's so easy.

//make sure you import relavent apis

import flash.display.LineScaleMode;
import flash.display.CapsStyle;
import flash.display.JointStyle;

public var _cricleObj            :Sprite;

public var _lineSize            :Number    = 1;

//Now draw your circle

_cricleObj = new Sprite();

_cricleObj.graphics.lineStyle(_lineSize, 0xFFFF00, 1, false, LineScaleMode.VERTICAL, CapsStyle.NONE, JointStyle.MITER, 3);

_cricleObj.graphics.beginFill(0xFF,1);
_cricleObj.graphics.drawCircle(0,0,50);
_cricleObj.graphics.endFill();

_cricleObj.addEventListener(Event.ENTER_FRAME, reDrawCircle);

public function reDrawCircle(e:Event):void
{
            _lineSize +=1;
            _cricleObj.graphics.clear();
            _cricleObj.graphics.lineStyle(_lineSize, 0xFFFF00, 1, false, LineScaleMode.VERTICAL, CapsStyle.NONE, JointStyle.MITER, 3);
            _cricleObj.graphics.beginFill(0xFF,1);
            _cricleObj.graphics.drawCircle(0,0,50);
            _cricleObj.graphics.endFill();

  }

thats all.

That was the solution, thanks for that code example.

But I have now come across a much larger problem with getting the dynamic circle to appear correctly:

You can use the graphics class to change the line style, you need to access the shape inside the movie clip in order to use the class.

you can access a shape in a movieclip by using getChildAt. then you can use the lineStyle function.

graphics.lineStyle(thickness, color, transparency).

Although you use getChildAt to access a shape in a movieclip by using getChildAt. still you can't change it's linestyle.

if you use graphics.lineStyle(thickness, color, transparency) on that movieClip it can be used to draw a new graphic but can't alter the current one.

If I am wrong please show us an example with clear codes.

I think you are right getnaleen, thanks.

I don't know why, thought i did before but i just tried it and it doesn't work.

sorry..
