update method

@override void update(double t)

Sets the motion to a specific point in time. The t value that is passed in is a normalized value 0.0 to 1.0 of the duration of the motion. Every motion will always recieve a callback with the end time point (1.0), unless it is cancelled.

Implementation

@override
void update(double t) {
  int currentRepeat =
      math.min((t * numRepeats.toDouble()).toInt(), numRepeats - 1);
  for (int i = math.max(_lastFinishedRepeat, 0); i < currentRepeat; i++) {
    if (!motion._finished) motion.update(1.0);
    motion._reset();
  }
  _lastFinishedRepeat = currentRepeat;

  double ta = (t * numRepeats.toDouble()) % 1.0;
  motion.update(ta);

  if (t >= 1.0) {
    motion.update(1.0);
    motion._finished = true;
  }
}
