Time for action – supporting collision detection

1. Add the following properties and methods needed to support collision detection to the Sprite class:

   Public ReadOnly Property BoundingBoxRect As Rectangle
       Get
           return new Rectangle(
             CInt(_location.X) + BoundingXPadding,
             CInt(_location.Y) + BoundingYPadding,
             frameWidth - (BoundingXPadding * 2),
             frameHeight - (BoundingYPadding * 2))
       End Get
   End Property
   
   Public Function IsBoxColliding(OtherBox as Rectangle) As Boolean
       return BoundingBoxRect.Intersects(OtherBox)
   End Function
   
   Public Function IsCircleColliding(
     otherCenter As Vector2, otherRadius As Single) As Boolean
       If (Vector2.Distance(Center, otherCenter) <
           (CollisionRadius + otherRadius)) Then
           return true
       Else
           return false
       End If
   End Function

What just happened?

The BoundingBoxRect property provides a Rectangle object equivalent to the location and size of the sprite, accounting for the padding...
