Time for action – basic Sprite properties

1. Add public properties to allow access to the Sprite class' members:

   public Vector2 Location
   {
       get { return location; }
       set { location = value; }
   }
   
   public Vector2 Velocity
   {
       get { return velocity; }
       set { velocity = value; }
   }
   
   public Color TintColor
   {
       get { return tintColor; }
       set { tintColor = value; }
   }
   
   public float Rotation
   {
       get { return rotation; }
       set { rotation = value % MathHelper.TwoPi; }
   }

What just happened?

The Location, Velocity, and TintColor properties are simple pass-throughs for their underlying private members as no additional code or checks need to be done when these values are manipulated.

When Rotation is set, the value is divided by MathHelper.TwoPi and the remainder of the result is stored in the rotation member. This is a shorthand way of keeping the value between 0 and 2*pi. If a value within this range is passed into Rotation, the remainder of the division will equal the passed value. If the...
