Yeah, your code is just saying "If the Kinect can see my foot, then do this code; if not, do this code." You need to change the code to have it based on where your foot is. However, I have no idea how to do this... I believe you find the x and y coordinates of you foot, and then base your code on those numbers. But don't make them exact numbers. Make then in a limit by using the "Range and Coerce" block from the comparison palette. It should allow you to base the cases on where your foot is. I would use this because your foot won't be able to stay in one exact coordinate for more than a few milliseconds.
Hope I helped!
