In this chapter, we wrote a lot of code. But, it gave us the possibility of bringing our game to life. In fact, we first programmed the PlayerController, which is responsible for moving the player's spaceship as well as shooting according to the player's input. Then, we saw how it's possible to automate the process of moving and shooting with just a few lines of code by writing the EnemyController.
