class UNavCollision : public UNavCollisionBase

Variables

  Type Name Description
Public variable TSubclassOf< class UNavArea > AreaClass Navigation area type that will be use when this static mesh is used as a navigation obstacle.
Public variable uint32: 1 bCreateOnClient If false, will not create nav collision when connecting as a client
Public variable uint32: 1 bForceGeometryRebuild If set, convex geometry will be rebuild instead of using cooked data
Public variable uint32: 1 bGatherConvexGeometry If set, convex collisions will be exported offline for faster runtime navmesh building (increases memory usage)
Public variable FGuid BodySetupGuid Guid of associated BodySetup
Public variable TArray< FNavCollisionBox > BoxCollision List of nav collision boxes
Public variable TNavStatArray< int32 > ConvexShapeIndices  
Public variable FFormatContainer CookedFormatData Cooked data for each format
Public variable TArray< FNavCollisionCylinder > CylinderCollision List of nav collision cylinders

Public function Virtual void  
Public function Virtual void

Setup ( UBodySetup* BodySetup
)

 Tries to read data from DDC, and if that fails gathers navigation collision data, stores it and uploads to DDC

Overridden from UObject

  Type Name Description
Public function Virtual void

GetResourceSizeEx ( FResourceSizeEx& CumulativeResourceSize
)

 Get the size of the object/resource for use in memory tools or to display to artists/LDs in the Editor This is the extended version which separates up the used memory into different memory regions (the actual definition of which may be platform specific).
Public function Virtual Const bool Called during saving to determine the load flags to save with the object.
Public function Virtual Const bool

NeedsLoadForTargetPlatform ( const ITargetPlatform* TargetPlatform
)

 Called during saving to determine the load flags to save with the object.
Public function Virtual void Called after the C++ constructor and after the properties have been initialized, including those loaded from config.
Public function Virtual void Do any object-specific cleanup required immediately after loading an object.
Public function Virtual void Handles reading, writing, and reference collecting using FArchive.
