UKismetMathLibrary::GetAxes
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticUFUNCTIONBlueprintPure
Description
Retrieves the three orthogonal axes of the reference frame described by rotation A. This is the Blueprint-callable version of BreakRotIntoAxes.
Caveats & Gotchas
- • GetAxes and BreakRotIntoAxes are functionally identical — GetAxes is the Blueprint-exposed wrapper. In C++ prefer BreakRotIntoAxes to keep call sites consistent, or call A.GetAxes() directly on the FRotator.
- • All three output vectors are unit vectors computed from the same rotation matrix, so they are guaranteed to be orthogonal to each other. Do not re-orthogonalize them.
Signature
static ENGINE_API void GetAxes(FRotator A, FVector& X, FVector& Y, FVector& Z);Parameters
| Name | Type | Description | Default |
|---|---|---|---|
| A | FRotator | The rotation whose axes to compute. | — |
| X | FVector& | Receives the forward (X) unit vector. | — |
| Y | FVector& | Receives the right (Y) unit vector. | — |
| Z | FVector& | Receives the up (Z) unit vector. | — |
Return Type
void Example
Build a movement input vector in camera space C++
FVector CamX, CamY, CamZ;
UKismetMathLibrary::GetAxes(CameraRotation, CamX, CamY, CamZ);
FVector InputDir = CamX * ForwardAxis + CamY * RightAxis;
InputDir.Z = 0.f;
InputDir.Normalize();
