Struct GraphHitInfo

float distance

Distance from origin to point.

GraphNode node

Node which contained the edge which was hit.

If the linecast did not hit anything then this will be set to the last node along the line's path (the one which contains the endpoint).

For layered grid graphs the linecast will return true (i.e: no free line of sight) if when walking the graph we ended up at X,Z coordinate for the end node even if end node was on a different level (e.g the floor below or above in a building). In this case no node edge was really hit so this field will still be null.

Vector3 origin

Start of the line/ray.

Note that the point passed to the Linecast method will be clamped to the closest point on the navmesh.

Vector3 point

Hit point.

In case no obstacle was hit then this will be set to the endpoint of the line.

Vector3 tangent

Tangent of the edge which was hit.

Vector3 tangentOrigin

Where the tangent starts.

tangentOrigin and tangent together actually describes the edge which was hit.
