that is not moving. Moving may be as simple as following another pawn, or tracking a freshly
spawned health pickup, while the other category contains things such as aiming or firing
The bots, or computer controlled pawns, can be configured to have a multitude of

instructs the bot to run for cover after taking damage, or to only fire after being fired upon.
We won't cover any of that in depth, but we will cover how to attract pawns towards our
newly created pickups in this chapter, and we'll get more in depth with their intelligence
in the following chapter.
