Time for action – drawing the Sprite

1. Add the Draw() method to the Sprite class:

   Public Overridable Sub Draw(spriteBatch As SpriteBatch)
       spriteBatch.Draw(
           Texture,
           Center,
           Source,
           tintColor,
           rotation,
           new Vector2(CSng(frameWidth / 2), CSng(frameHeight / 2)),
           1.0,
           SpriteEffects.None,
           0.0)
   End Sub

What just happened?

The Draw() method consists of a single call to the SpriteBatch.Draw() method, using an overload of the method that allows for rotation and scaling.

Because we are specifying a rotation, we need to identify a center point for the rotation to be based around (new Vector2(CSng(frameWidth / 2), CSng(frameHeight / 2))). Instead of specifying a destination rectangle, we specify a vector that points to the center of the area, the object will occupy on the screen (the Center property of the Sprite class).
