Wandering Hazards

In this chapter, we’ll implement an obstacle type that we’ll call Wanderer. They’ll look like the Patrollers we implemented in the last chapter, but instead of moving along a set of points repeatedly, they’ll be confined to a rectangular region, and they’ll periodically wander over to a new point inside that region. We can put multiple Wanderers in the same region, and they’ll all act separately, finding a new place to move to every so often. We’ll use a little bit of random number generation to make them wait some amount of time between a minimum and maximum number of seconds before moving again, which we can configure in the Inspector.
