UKismetMathLibrary::MakeRotFromXZ

function Engine Blueprint Since 4.0

#include "Kismet/KismetMathLibrary.h"

Access: public Specifiers: staticBlueprintPure

Description

Builds a rotator from a primary X (forward) and secondary Z (up) axis, computing Y (right) as the cross product. X is fixed; Z may shift slightly to ensure orthogonality.

Caveats & Gotchas

• Z is the secondary axis and may be rotated in the XZ plane to enforce orthogonality with X; use this when you care about forward direction and up hint but not exact right direction.
• Parallel X and Z inputs produce an undefined result without a runtime error.

Signature

static UE_INL_API FRotator MakeRotFromXZ(const FVector& X, const FVector& Z);

Parameters

Name	Type	Description	Default
X	const FVector&	Primary (fixed) forward axis.	—
Z	const FVector&	Secondary up axis, adjusted minimally for orthogonality.	—

Return Type

FRotator

Example

Build an orientation from camera forward and world up C++

FVector CamForward = CameraComponent->GetForwardVector();
FVector WorldUp = FVector::UpVector;
FRotator Rot = UKismetMathLibrary::MakeRotFromXZ(CamForward, WorldUp);
