Summary
The complete AI project created in this chapter can be found in the topic's companion
files (code bundle) in the
ai
folder of this chapter. I recommend that you open it and
then test it out. Using the first-person controller, the player can navigate the level,
avoid enemies, and also attack when enemies are in range using the Space bar,
as shown here:
