示例1: GetClosestNodeToPosition
//------------------------ GetClosestNodeToPosition ---------------------------
//
// returns the index of the closest visible graph node to the given position
//-----------------------------------------------------------------------------
int Raven_PathPlanner::GetClosestNodeToPosition(Vector2D pos)const
{
double ClosestSoFar = MaxDouble;
int ClosestNode = no_closest_node_found;
//when the cell space is queried this the the range searched for neighboring
//graph nodes. This value is inversely proportional to the density of a
//navigation graph (less dense = bigger values)
const double range = m_pOwner->GetWorld()->GetMap()->GetCellSpaceNeighborhoodRange();
//calculate the graph nodes that are neighboring this position
m_pOwner->GetWorld()->GetMap()->GetCellSpace()->CalculateNeighbors(pos, range);
//iterate through the neighbors and sum up all the position vectors
for (NodeType* pN = m_pOwner->GetWorld()->GetMap()->GetCellSpace()->begin();

//distance
