[dial] 360 degrees no clipping - counting each revolution

    Hi,
    I want to use a [dial] object to control a timer. Where one full turn is 60s, and when you go all the way around, it can send a bang or something to make another number box go up one (minutes).
    I first tried [match 59 0] and [match 0 59] (for turning the dial backwards). that worked well, except when I turn the dial fast (dial skips numbers when you go fast). I then tried something with [>] which I can only get working well for increasing values, and won't let you decrease.
    Has anyone did anything like this before? Any ideas?

      here's 2 tries in 1 patch with comments, as you can see in the left one, it works unless you try to spin the dial too fast.

      It's a little hackish but try this. You can't spin the dial extremely fast but it seems to work at reasonable speeds.
      //--dialhelper.js--
      inlets = 1; outlets = 1;
      var last = 0.0;
      function msg_float(current) { // dial outputs neg nums if spun too fast.. current = Math.abs(current);
      if (last > 0.6 && current < 0.4) { outlet(0, "inc"); last = 0.0; } else if (last < 0.4 && current > 0.6) { outlet(0, "dec"); last = 1.0; } else last = current; }
      //-----------

      Thank you so much tristanb!
      This seems to work great so far, I will put it into my patch later to see if it works as well in my full patch.
      I was just thinking maybe it would require a javascript solution, and that I wanted to start learning js anyway just to have it as an extra tool I could use.
      Thanks again, and of course it would be interesting to see if anyone else has alternate solutions to this as well.

      Yeah, I was thinking there was probably an easier way, but I just went straight for the js. With some thinking, you could recreate that script with regular max objects though. I'd also be interested to see if someone else has a different way!
