Time for action – Sprite constructor

1. Add a constructor to the Sprite class:

   public Sprite(
       Vector2 location,
       Texture2D texture,
       Rectangle initialFrame,
       Vector2 velocity)
   {
       this.location = location;
       Texture = texture;
       this.velocity = velocity;
   
       frames.Add(initialFrame);
       frameWidth = initialFrame.Width;
       frameHeight = initialFrame.Height;
   }

What just happened?

The constructor for the Sprite class directly sets the location, texture, and velocity members to the passed parameter values. It then sets the frameWidth and frameHeight variables by extracting that information from the Rectangle.
