Variables

  Type Name Description
Public variable uint32: 1 bDynamic Is this path generated on dynamic navmesh (i.e. one attached to moving surface)
Protected variable uint32: 1 bStringPulled Does this path contain string pulled path? If true then NumPathVerts > 0 and OutPathVerts contains valid data.
Protected variable uint32: 1 bWantsPathCorridor If set to true path instance will contain path corridor generated as a part pathfinding call (i.e. without the need to generate it with GeneratePathCorridorEdges
Protected variable uint32: 1 bWantsStringPulling If set to true path instance will contain a string pulled version.
Public variable TArray< FNavLinkId > CustomNavLinkIds  
Public variable TArray< NavNodeRef > PathCorridor Sequence of navigation mesh poly ids representing an obstacle-free navigation corridor
Public variable TArray< FVector::FReal > PathCorridorCost For every poly in PathCorridor stores traversal cost from previous navpoly
