Chapter 5. Enemy and Friendly AIs
Artificial Intelligence, also known as AI, is something that you'll see in every video game that you play. First-person shooter, real-time strategy, simulation, role playing games, sports, puzzles, and so on, all have various forms of AI in both large and small systems. In this chapter, we'll be going over several topics that involve creating AI, including techniques, actions, pathfinding, animations, and the AI manager. Then, finally, we'll put it all together to create an AI package of our own.
In this chapter, you will learn:
