Variables

  Type Name Description
Protected variable UProperty Category, EditAnywhere uint8: 1 bComplexTrace Indicates the trace should perform a complex trace
Protected variable UProperty Category, EditAnywhere uint8: 1 bIgnoreInstigatorActor Indicates the trace should ignore the source actor
Protected variable UProperty Category, EditAnywhere uint8: 1 bIgnoreSourceActor Indicates the trace should ignore the source actor
Protected variable UProperty Category, EditAnywhere uint8: 1 bMultiTrace Indicates whether the trace should be a multi trace or a single trace
Protected variable UProperty Category, EditAnywhere FCollisionProfileName CollisionProfileName The collision profile name to use instead of trace channel (does not work for async traces)
Protected variable UProperty Category, EditAnywhere FVector DefaultSourceOffset The default source location offset used by GetSourceOffset
Protected variable UProperty Category, EditAnywhere FScalableFloat DefaultSweptTraceBoxHalfExtentX The default swept extents used by GetSweptTraceExtents when the trace type is set to Box
Protected variable UProperty Category, EditAnywhere FScalableFloat DefaultSweptTraceBoxHalfExtentY The default swept extents used by GetSweptTraceBoxHalfExtents when the trace type is set to Box
Protected variable UProperty Category, EditAnywhere FScalableFloat DefaultSweptTraceBoxHalfExtentZ The default swept extents used by GetSweptTraceBoxHalfExtents when the trace type is set to Box
Protected variable UProperty Category, EditAnywhere FScalableFloat DefaultSweptTraceCapsuleHalfHeight The default swept trace radius used by GetSweptTraceRadius when the trace type is set to Capsule
Protected variable UProperty Category, EditAnywhere FScalableFloat DefaultSweptTraceRadius The default swept trace radius used by GetSweptTraceRadius when the trace type is set to Sphere or Capsule
Protected variable UProperty Category, EditAnywhere FRotator DefaultSweptTraceRotation The default swept rotation (relative to the trace direction) used by GetSweptTraceRotation when the trace type is set to Capsule or Box
Protected variable UProperty Category, EditAnywhere FScalableFloat DefaultTraceLength The default trace length to use if GetTraceLength is not overridden by a child
Protected variable UProperty Category, EditAnywhere FVector ExplicitTraceDirection An explicit trace direction to use (default uses pawn control rotation or actor forward vector in GetTraceDirection)
Protected variable UProperty Category, EditAnywhere TEnumAsByte< ETraceTypeQuery > TraceChannel The trace channel to use
Protected variable UProperty Category, EditAnywhere ETargetingTraceType TraceType The trace type (i.e. shape) to use
