Detailed Description

Returned by graph ray- or linecasts containing info about the hit.

This is the return value by the Pathfinding.IRaycastableGraph.Linecast methods. Some members will also be initialized even if nothing was hit, see the individual member descriptions for more info.

GraphHitInfo ( Vector3  point)

Member Data Documentation

◆ node

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 but the 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.

◆ origin

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.

◆ point

Vector3 point

Hit point.

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

◆ tangent

Vector3 tangent

Tangent of the edge which was hit.

◆ tangentOrigin

Vector3 tangentOrigin

Where the tangent starts.

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

Property Documentation

◆ distance

float distance
