Structure of TAEB AI Behavioral Part 3

For the personality described the the Perl module Explorer.pm, each time the method next_action is called from the base class TAEB::AI::Behavioral::Personality, the member list is scanned for the behavior with the highest urgency.

The member list this is scanned is called prioritized_behaviors, which is an array of strings that are the humand-readable name of a possible behavior of the agent. The elements of prioritized_behaviors are(listed in the order of scanning from top to bottom) is: FixHunger, Heal, FixStatus, Defend, AttackSpell, BuffSelf, Kite, Melee, ProjectFiles, Vault, Shop, Carrion, GetItems, Equip, Identify, DipForExcalibur, Wish.

When the next_action is called it first performs any post-behaviors by sending the done method to complete any steps from the current behavior, if defined. The behavior Luckstone appears to be the only behavior with an implementation of the done method. After calling done, next_action will scan the entire prioritized_behaviors array, looking fof the first behavior with the highest urgency. If there are multiple behaviors with the same urgency and the urgency is the largest, then the first one found is the most urgent behavior. As next_action goes through each behavior in the prioritized_behaviors list, it executes each behavior's prepare method. The prepare method of a TAEB::AI::Behavior instance performs setup in preperation for a behavior to be chosen as the most urgent next behavior. For example, for the Explore.pm behavior, the prepare method performs a search of the nethack maze from its current position. When next_action completes its iterations over the contents of the prioritized_behaviors, all behaviors have had their prepare methods executed, but only one behavior is the most urgent and will be converted into a nethack command, TAEB::AI::Action subclass.
