XY Values to a Single Linear Value


    Jul 25 2011 | 1:55 pm
    Hi guys,
    What I want to do is use the analogue sticks on my xbox 360 controller as jog wheels to control sample players. I.e. when I rotate the sticks at their outer edge, a clockwise motion plays the files forwards, counterclockwise backwards, the faster the rotation, the faster sample plays etc etc.
    To do this I want to take the x and y values from the sticks and convert them into a single linear value. I'm sure there's an obvious solution to this, but I can't see one.
    Any ideas guys?

      Hi
      while I'm looking at this, read this thread, particularly the use of [cartopol].

      Hi Brendan,
      Thanks, [cartopol] was exactly what I was looking for!

      For my purposes (as a live performance instrument) I'm going to use some sort of averaging to convert changes in angle into a float between -2 and 2 for send into [groove~]

      If your maths is better than mine (likely), then your solution may well be more elegant than this:
