Variables

  Type Name Description
Protected variable TEnumAsByte< ENavigationAreaMode::Type > ApplyMode  
Protected variable TWeakObjectPtr< UClass > AreaClassOb This should take a value of a game specific navigation modifier
Protected variable uint8: 1 bExpandTopByCellHeight If set, area shape will be extended at the top by one cell height
Protected variable uint8: 1 bIncludeAgentHeight If set, area shape will be extended by agent's height to cover area underneath like regular colliding geometry
Protected variable uint8: 1 bIsLowAreaModifier Set when this modifier affects low spans in navmesh generation step
Protected variable FBox Bounds  
Public variable float Cost Transient value used for navigation modifiers sorting. If < 0 then not set
Public variable float FixedCost  
Protected variable TArray< FVector > Points  
Protected variable TWeakObjectPtr< UClass > ReplaceAreaClassOb  
Protected variable TEnumAsByte< ENavigationShapeType::Type > ShapeType
