How it works...
The AI begins in an idle state. As long as it has some items in the
targetableObjects
list, it will run the
sense
method on each update. If it sees anything, it will switch to the
Follow
state and stay there until it loses track of the target.
The
sense
method consists of a
for
loop that sends rays in an arc representing a field of
view. Each ray is limited by
sightRange
and the loop will exit if a ray has collided with
anything from the
targetableObjects
list.
