I've been asked to provide a control value based on how far the drag is via distance. So far so good. What my designer wants is a value change of every 20 pixels or so (control is 150px tall @ the moment) - so every 20 pixels = a change of 1. This will require multiple touch and drags but he's fine with it. The math is probably simple, but it's eluding me this morning. How can I easily convert my distance (I also have an increment Bool so I know whether it's addition or subtraction) to an appropriate value?
