Struct NNInfo

float distanceCostSqr

Cost for picking this node as the closest node.

This is typically the squared distance from the query point to position.

However, it may be different if the NNConstraint used a different cost function. For example, if NNConstraint.distanceMetric is DistanceMetric.ClosestAsSeenFromAbove(), then this value will be the squared distance in the XZ plane.

This value is not guaranteed to be smaller or equal to the squared euclidean distance from the query point to position. In particular for a navmesh/recast graph with a DistanceMetric.ClosestAsSeenFromAboveSoft NNConstraint it may be slightly greater for some configurations. This is fine because we are only using this value for the rough distance limit performanced by AstarPath.maxNearestNodeDistance, and it's not a problem if it is slightly inaccurate.

If node is null, then this value is positive infinity.

GraphNode node

Closest node.

May be null if there was no node which satisfied all constraints of the search.

Vector3 position

Closest point on the navmesh.

This is the query position clamped to the closest point on the node.

If node is null, then this value is (+inf, +inf, +inf).

NNInfo Empty = new NNInfo(null, Vector3.positiveInfinity, float.PositiveInfinity)

Vector3 clampedPosition

Closest point on the navmesh.
