Creating an OrbitingMovement Component

This component is similar to RotatingMovementComponent in that it is designed to make the components parented to it move in a particular way. In this instance, it will move any attached components in an orbit around a fixed point at a fixed distance.

This could be used, for example, for a shield that orbits around a character in an Action RPG.

How to do it...

1. Create a new SceneComponent subclass and add the following properties to the class declaration:

   UPROPERTY()
   bool RotateToFaceOutwards;
   UPROPERTY()
   float RotationSpeed;
   UPROPERTY()
   float OrbitDistance;
   float CurrentValue;

2. Add the following to the constructor:

   RotationSpeed = 5;
   OrbitDistance = 100;
   CurrentValue = 0;
   RotateToFaceOutwards = true;

3. Add the following ...
