I'm attempting to write a simple test app that counts down by the second and displays it on the screen. I have used the following to get my current results:

Code: Select all

      Time currentTime = new Time();
      currentTime.setToNow();
      
      int milliDiff = (int) (currentTime.toMillis(false) - startTime.toMillis(false));
      
      if(milliDiff > 1000) {
         startTime.setToNow();
         sec--; // in class scope to count # seconds
         millis = milliDiff;
         
         if(sec < 0) {
            sec = 0;
         } else if (sec < 10) {
            Assets.tick.play(100);
         }               
         
      }



The display code is elsewhere, and the FPS < 1 second. If I set the value of milliDiff to 500, then it seems to run at close to the proper speed.

I know there are other approaches to this problem, but can anyone explain why this fails?

Thanks.
