Variables

  Type Name Description
Public variable bool bDebugQuery  
Public variable bool bFindInitialOverlaps Whether we want to find out initial overlap or not.
Public variable bool bIgnoreBlocks Whether to ignore blocking results.
Public variable bool bIgnoreTouches Whether to ignore touch/overlap results.
Public variable bool bReturnFaceIndex Whether we want to return the triangle face index for complex static mesh traces
Public variable bool bReturnPhysicalMaterial Whether we want to include the physical material in the results.
Public variable bool bSkipNarrowPhase Whether to skip narrow phase checks (only for overlaps).
Public variable bool bTraceComplex Whether we should trace against complex collision
Public variable bool bTraceIntoSubComponents Whether to ignore traces to the cluster union and trace against its children instead.
Public variable FMaskFilter IgnoreMask Extra filtering done on the query. See declaration for filtering logic
Public variable EQueryMobilityType MobilityType Filters query by mobility types (static vs stationary/movable)
Public variable FName OwnerTag Tag used to indicate an owner for this trace
Public variable TStatId StatId StatId used for profiling individual expensive scene queries
Public variable FName TraceTag Tag used to provide extra information or filtering for debugging of the trace (e.g. Collision Analyzer)
