Chapter 2. Patrolling

Patrolling is a simple extension to pathfinding. Instead of just having a single target in mind, we might have two or more points. We might go back and forth between them, or travel in a never-ending loop.

In this chapter, you will learn about:

• How patrolling works
• Patrolling in Quick Path, React, and RAIN AI packages
• Getting to know more about behavior trees
• Creating patrols that go to different points in a level by not always following the same path

Patrolling is a way to get an object from point A to point B and then to point C, and so on. Pathfinding is still required to get from one waypoint to another, but here, we daisy-chain them into a larger, more meaningful path.
