==Concept==
'''Behavior Histories''' keep track of the last time a [[Behavior]] was executed by an agent. This allows for checking the [[Behavior Runtime|runtime]] of the current behavior and the [[Behavior Cooldown|time since the behavior was run]].

This is also tracked for [[Behavior Type|behavior types]] as well so that one can tell when a ''type'' was done regardless of the specific behavior that called it. For example, "when was the last time I did a MoveToTarget?" can be checked even though there might be dozens of different behaviors that call "MoveToTarget".

Additionally, it keeps track of [[Context]] times so that information can be accessed on when a particular behavior was run with a particular [[target]]. This allows the same behavior to be run without repeating it at a particular target. One example would be waving at a variety of passing villagers but not at the same villager on a repeated basis.

==Code==
For readability of code, the various maps and their components are kept in typedefs.
<nowiki>
typedef std::unordered_map<unsigned int, float> BehaviorHistoryMap;
typedef std::pair<unsigned int, float> BehaviorHistoryIdAndTime;

typedef std::unordered_map<ContextEntry, float> ContextHistoryMap;
typedef std::pair<ContextEntry, float> ContextHistoryIdAndTime;

typedef std::unordered_map<BehaviorType, float> BehaviorTypeHistoryMap;
typedef std::pair<BehaviorType, float> BehaviorTypeIdAndTime;</nowiki>
The actual objects are in the member variables in [[Brain]]:
<nowiki>
//////////////////////////////////////////////////////////////////////////
// History Tracking
BehaviorHistoryMap behaviorHistory; // History of recent behaviors I have performed (no context)
ContextHistoryMap contextHistory; // History of recent decisions I have performed (incl. behavior and context)
BehaviorTypeHistoryMap behaviorTypeHistory; // History of recent behaviors I have performed by type only</nowiki>
Each of the maps has functions for:
* Storing an entry
* Getting the last time from an entry
* Cleaning the history based on an expiry time
Cleaning the histories is called from the iteration of the [[Think Cycle|think cycle]]
