position property

@override SoundPosition position

Get the position of source.

Implementation

@override
SoundPosition get position {
  final s = source;
  if (s is DirectSource) {
    return unpanned;
  } else if (s is Source3D) {
    final p = s.position.value;
    return SoundPosition3d(x: p.x, y: p.y, z: p.z);
  } else if (s is AngularPannedSource) {
    return SoundPositionAngular(
      azimuth: s.azimuth.value,
      elevation: s.elevation.value,
    );
  } else if (s is ScalarPannedSource) {
    return SoundPositionScalar(scalar: s.panningScalar.value);
  } else {
    throw UnimplementedError('Cannot handle source $s.');
  }
}

@override void position=(SoundPosition value)

Set the source position.

Implementation

@override
set position(final SoundPosition value) {
  final s = source;
  if (s is DirectSource) {
    throw UnimplementedError(
      'You cannot set the `position` for an unpanned source.',
    );
  } else if (s is Source3D) {
    if (value is! SoundPosition3d) {
      throw PositionMismatchError(this, value);
    }
    s.position.value = Double3(value.x, value.y, value.z);
  } else if (s is AngularPannedSource) {
    if (value is! SoundPositionAngular) {
      throw PositionMismatchError(this, value);
    }
    s
      ..azimuth.value = value.azimuth
      ..elevation.value = value.elevation;
  } else if (value is SoundPositionScalar) {
    if (s is! ScalarPannedSource) {
      throw PositionMismatchError(this, value);
    }
    s.panningScalar.value = value.scalar;
  } else {
    throw UnimplementedError('Cannot handle sound position $value.');
  }
