How it works...
This recipe follows the pattern we established in the
Creating a trigger system
recipe. In
the
onTrigger
method, we apply
targetState
, which will change the behavior and
actions of the AI. For example, it can change from
PatrolState
to
AttackState
. We
only supply the class type and not a whole instance of the class since the AI should already
have the state and it might be configured already. In this way, we tell the AI to simply
change the state if it is available. We also have a
target
field, in case the new state re-
quires that.
