      class DJIHotpointMission

      @interface DJIHotpointMission : DJIMission
      Header:DJIHotpointMission.h
      Inherits From:DJIMission
      Description:

      This class represents a Hotpoint mission. In a Hotpoint mission, the aircraft will repeatedly fly circles of a constant radius around a specified point called a Hot Point. The user can control the aircraft to fly around the Hotpoint with a specific radius and altitude. During execution, the user can also use the physical remote controller to modify its radius and speed. It is not supported by Mavic Pro when using WiFi connection. It is not supported by Spark, Mavic Mini, Mavic Air 2 and Matrice 300 RTK.

      property radius
      @property(nonatomic, assign) float radius
      Header:DJIHotpointMission.h
      Description:

      Sets the circular flight path radius with which the aircraft will fly around the hotpoint. The value of this property should be in the range of [DJIHotpointMinRadius, DJIHotpointMaxRadius] meters.
