/5/ frame rate based content

• randomation requires processor power.
• we service older machines by reducing content if frame rate is low.
• in asdg nav, if frame rate is too low:
  • don't generate background stars
  • don't generate background title
  • reduce movie to medium quality (if frame rate is *really* low)
  • base programmatic animation on time, not framerate

how to calculate frame rate

• on any frame, attach this code:
  var startTimeCheck = getTimer();
var startFrame = _currentFrame;
• on a subsequent frame, attach this code:
  var endTimeCheck = getTimer();
var numFrames = _currentFrame - startFrame;
var elapsedSeconds = (endTimeCheck - startTimeCheck) / 1000;
var fps = numFrames / elapsedSeconds;
trace(fps);
• the variable fps tells you the framerate. you can use it to conditionally include or exclude content
