Introduction

Artificial intelligence can cover a variety of things in UDK, so we won't delve too far down
that path, at least not in this chapter. Here, we'll briefly cover it, and how the AI interacts with
pickups throughout the game, specifically what attracts them to certain pickups. Furthermore,
we'll dive into creating our own pickups and how they interact with our pawn's inventory.

So with that, let's talk about AI.

Understanding AI

The main class that handles player actions in UDK is the PlayerController class.
Similarly, actions are controlled by the AIController class. Considering that they both
inherit Controller, they share quite a bit of functionality. For the most part, AI controllers
don't necessarily need a pawn, just like a player controller.
