public class LeaderFollowingBehavior
extends SeekBehavior

This is similar to pursuit behavior, but pursuiers must stay away from the pursued path. In order to stay away from that path the pursuers resort to "evade". Furthermore pursuers use "arrive" instead of "seek" to approach to their objective.

LeaderFollowingBehavior

public LeaderFollowingBehavior(Agent agent,
                       Agent target,
                       float distanceToEvade,
                       float distanceToChangeFocus,
                       float minimunAngle)

Parameters:

distanceToChangeFocus - Distance to change the focus: After the agent distance to the target is lower than this distance, the agent will progressively stop seeking the future position and instead, directly seek the target.

distanceToEvade - If the agent is in front of the target and the distance to him is lower than distanceToEvade, the agent will evade him in order to stay out of his way.

minimunAngle - Minimum angle betwen the target velocity and the vehicle location.

Throws:

BehaviorExceptions.TargetNotFoundException - If target (leader) is null

SteeringExceptions.NegativeValueException - If distanceToEvade is lower than 0 or if distanceToEvade is lower than 0
