drainEvents method

@override List<PhysicsEvent3D> drainEvents()

What happened since the last drain, oldest first.

Implementation

@override
List<PhysicsEvent3D> drainEvents() {
  if (_gone) return const [];
  final out = <PhysicsEvent3D>[];
  while (true) {
    final n = jj_drain_events(handle, _events, _eventCapacity);
    for (var i = 0; i < n; i++) {
      final e = _events[i];
      if (e.type < 1 || e.type > _eventTypes.length) continue;
      out.add(
        PhysicsEvent3D(
          _eventTypes[e.type - 1],
          e.bodyA,
          e.bodyB,
          point: Vector3(e.point[0], e.point[1], e.point[2]),
          normal: Vector3(e.normal[0], e.normal[1], e.normal[2]),
          depth: e.depth,
        ),
      );
    }
    if (n < _eventCapacity) break;
    if (_eventCapacity < 8192) {
      _drop(_events);
      _eventCapacity *= 2;
      _events = _alloc<JJ_Event>(_eventCapacity);
    }
  }
  return out;
