Detailed Description

Assign a random route to every ACarlaWheeledVehicle entering the trigger volume.

Routes must be added in editor after placing this actor into the world. Spline tangents are ignored, only locations are taken into account for making the route.

static

Searches every ARoutePlanner in the world for the route spline point closest to Location, and returns the road direction there (as a rotator built from the spline tangent).

Used by editor tools that want to align spawned props (e.g. road decals) to the flow of traffic. Returns false, leaving OutRotation untouched, if no route spline point is found within SearchRadius.
