class CircleSensor(shapes.Circle, sensor_base.SensorBase):
    """A circular invisible sensor attached to another actor.

    `CircleSensor` creates a circular detection area around the parent actor.
    Any actor that overlaps with this circle will be detected. The sensor
    itself is invisible and never detects the parent actor.

    Use `actor.register_sensor(CircleSensor, distance=<pixels>)` to attach it.

    Args:
        actor: The parent actor this sensor belongs to.
        distance: Radius of the circular detection area in pixels.

    Examples:
        ::

            player = Actor((100, 100))
            player.register_sensor(CircleSensor, distance=50)
