FAQ

Q) Why do we set the bee to inactive when it gets to -100? Why not just zero since zero is the left-hand side of the window?

A) The bee graphic is 60 pixels wide and its origin is at the top left pixel. As a result, when the bee is drawn with its origin at x equals zero, the entire bee graphic is still on screen for the player to see. By waiting until it is at -100, we can be sure it is out of the player's view.

Q) How do I know how fast my game loop is?

A) If you have a modern NVIDIA graphics card, you might be able to already by configuring your GeForce Experience overlay to show the frame rate. To measure this explicitly using our own code, however, we will need to learn a few more things. We will add the ability to measure and display the current frame rate in Chapter 5, Collisions, Sound, and End Conditions – Making the Game Playable.
