No Animation Knowledge!

I'd use the paintable canvas for this, drawing each half and clipping the part that would overlap the other half. This thread should give you a starting point to work from:

Animate Fill Level On Irregular Shaped Component

The quick and dirty solution would be to place background-colored, borderless empty objects in front of the level indicator to obscure it where the irregular steps are. The precision solution would be to draw exactly what you need with the paintable canvas.
