update method

void update(double seconds)

Runs one frame of seconds real seconds in the isolate: what a view pacing a handle opened with ownsClock: false calls once a frame. The steps it runs publish as they do on the isolate's own clock.

Throws a StateError on a handle whose isolate keeps its own clock: two clocks would step the world twice as fast.

Implementation

void update(double seconds) {
  if (ownsClock) {
    throw StateError(
      'this simulation keeps its own clock; open it with ownsClock: false '
      'to step it by advance',
    );
  }
  if (_disposed) return;
  _link.send(<Object?>[LinkWords.advance, seconds]);
}
