@d-healey Yes of course, stupid me, I have to learn to check the documentation. Thank you David!

How do I animate an arc?
I have this

p.addArc([0,0, this.getWidth(), this.getHeight()/2], Math.PI * 1.2, Math.PI * 2.8);

Which will give a nice arc, and now I want to animate it, so that it will follow my slider which goes from 0 - 1
I've tried a lot of stuff using

this.getValue()

multiplying with the different values in the arc,
but it will always break the curve, any tip would be much appreciated

@TNTHM this is done with a vector knob

@TNTHM if it's vector knobs you can at least let the user change the colour of them.

@Natanr sorry, I can't solve that for you

@Lindon thank you, it works just the way I would like it to!

@Lindon thank you, I'll try your example!
