update method

void update(double delta)

Increments each track entry TrackEntry.getTrackTime, setting queued animations as current if needed.

Implementation

void update(double delta) {
  _bindings.spine_animation_state_update(_state, delta);

  final numEvents = _bindings.spine_animation_state_events_get_num_events(_events);
