Keeping Score
You have levels and end-game logic now, but what's the fun when your score is
always zero? In this section, you'll flesh out scoring for the game. You're already
displaying the score at the end of the game, but you'll want to let players see
their scores as they play. To do that, add a class-level SpriteFont variable to your Game1
class, with which you'll draw the score:
SpriteFont spriteFont;
And yes, that's right...the next thing that you'll need to do is add a new spritefont to your project. Right-click the Content\Fonts folder in Solution Explorer and select Add → New Item.... Select the Sprite Font template on the right and name the file Tahoma.spritefont, as shown in Figure 15-3.
