Variables

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< uint32 ...

 

CustomLinkIds

Set of unique link Ids

Public variable

TArray< NavNode...

 

PathCorridor

Sequence of navigation mesh poly ids representing an obstacle-free navigation corridor

Public variable

TArray< float >

 

PathCorridorCost

For every poly in PathCorridor stores traversal cost from previous navpoly
