UKismetMathLibrary::GetUpVector
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticUFUNCTIONBlueprintPure
Description
Returns the world-space unit vector pointing in the up (Z+) direction for the given rotation. Equivalent to rotating FVector::UpVector by InRot.
Caveats & Gotchas
- • For a character standing upright with no roll, this returns approximately (0,0,1). Adding roll rotates this vector, so for terrain-following normals you should query the surface normal directly rather than relying on the character's up vector.
- • This is the up of the rotation's local frame, not the world up — useful for tilted surfaces and vehicles, but can mislead if you only expected a world-up check.
