Gets the direction to which the control is pointing. It is based on the anglePosition value, but if distanceFromCenter is less than invalidRadius, the direction is considered as Direction.NONE.

directionType

private JoystickView.DirectionType directionType

The control directions type.

distanceFromCenter

private final Float distanceFromCenter

Calculates the distance between current position and center.

drawer

private ControlDrawer drawer

The control drawer.

invalidRadius

private Float invalidRadius

Invalid radius to be taken into account when obtaining control direction.

position

private final ImmutablePosition position

Gets the immutable position of control position.

viewParametricPosition

private final ImmutablePosition viewParametricPosition

Gets the parametric position of current position in the view circle.

viewRadius

private final Double viewRadius

Gets the radius of the view where the control is used.
