UKismetMathLibrary::MakeRotFromYX
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticBlueprintPure
Description
Builds a rotator with Y as the fixed primary axis and X adjusted to be orthogonal. Z is computed from the cross product. Useful when right-axis alignment is more important than forward direction.
Caveats & Gotchas
- • Argument order is (Y, X) — the primary (fixed) axis comes first; confusing the order with MakeRotFromXY will produce a mirrored or incorrect orientation.
- • Like all two-axis constructors, parallel inputs give a degenerate result.

Return Type
FRotator Example
Align a vehicle wheel to a lane direction C++
FVector LaneRight = LaneSpline->GetRightVectorAtSplinePoint(PointIdx, ESplineCoordinateSpace::World);
FVector ForwardHint = LaneSpline->GetDirectionAtSplinePoint(PointIdx, ESplineCoordinateSpace::World);
FRotator WheelRot = UKismetMathLibrary::MakeRotFromYX(LaneRight, ForwardHint);Tags
