PfCalcCost()

template<class Types>

bool CYapfCostRoadT< Types >::PfCalcCost ( Node & n, const TrackFollower * follower )

inline

Called by YAPF to calculate the cost from the origin to the given node.

Calculates only the cost of given node, adds it to the parent node cost and stores the result into Node::cost member.

Parameters

n	The node to consider.
follower	The track follower to the next node.

Returns

true iff the costs could be calculated.
