      • shouldFall

         abstract Boolean shouldFall(List<P> pushingForces)

        Determines if this pedestrian subject to pushingForces should fall. According to the work of Pelechano et al this should happen when the majority of pushing forces affecting one individual are approximately in the same direction and the sum of forces have a magnitude high enough to make it lose equilibrium.

      • repulse

         abstract P repulse(Node<T> other)

        Computes the repulsion force caused by a node that entered the comfortArea. This is derived from the work of Pelechano et al.

      • avoid

         abstract P avoid(Node<T> other)

        Computes the repulsion force caused by a node that entered the rectangleOfInfluence. This is derived from the work of Pelechano et al.

      • repulsionForces

         abstract List<P> repulsionForces()

        Computes the total repulsion force this node is subject to.

      • avoidanceForces

         abstract List<P> avoidanceForces()

        Computes the total avoidance force this node is subject to.

      • onFall

         abstract Unit onFall(Function1<Node<T>, Unit> listener)

        Adds a listener to be called when node falls.

      • isFallen

         abstract Boolean isFallen()

        Whether the pedestrian has fallen and it is thus an obstacle.

      • getComfortRay

         abstract Double getComfortRay()

        The comfort ray of this pedestrian, this is added to the radius of its Shape to obtain the comfortArea.

      • getComfortArea

         abstract Shape<P, A> getComfortArea()

        The comfort area of this pedestrian, it's a circle of radius Shape.radius + comfortRay.

      • getRectangleOfInfluence

         abstract Shape<P, A> getRectangleOfInfluence()

        Rectangle of influence. When a pedestrian enters this area, the node could experience a tangential avoidance force. See avoid.
