void | ExportNavigationData
(
const FString& FileName |
|
   |
int32 | Returns number of remaining tasks till build is complete | |

   |
void | GrabDebugSnapshot
(
FVisualLogEntry* Snapshot, |
|
   |
bool | Determines whether this generator is performing navigation building actions at the moment, dirty areas are also checked | |

bool | RebuildAll () |
Rebuilds all known navigation data |
  |
void | RebuildDirtyAreas
(
const TArray< FNavigationDirtyArea >& DirtyAreas |
Asks generator to update navigation affected by DirtyAreas |
  |
void | TickAsyncBuild
(
float DeltaSeconds |
Ticks navigation build If the generator is set to time sliced rebuild then this function will only get called when there is sufficient time (effectively roughly once in n frames where n is the number of time sliced nav data / generators currently building) |
