Introduction

In the previous chapters, we've covered topics that ranged from weapons and navigation, to
a heads-up display and AI. In this chapter, our recipes are going to cover things that may not
necessarily fit in one particular chapter, but are still very valuable in a number of applications.

We'll go over a new scheme for aiming our weapons and drawing a crosshair, as well as
allowing our pawn to flash continuously as its health depreciates, among other things.

Creating an army of companions

Going through a game alone is seldom any fun. We're social creatures so we enjoy the
company of others. What better way to celebrate this than by creating a group of companions
to follow us along on our journey? In this chapter, we'll explore how to create a small party of
companions who spawn at our location and reap the rewards of our adventure!
