UKismetMathLibrary::Conv_RotatorToVector
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticUFUNCTIONBlueprintPure
Description
Converts a rotator to its forward direction unit vector (X axis). This is identical to GetForwardVector and is the autocast used in Blueprint when you connect a Rotator pin to a Vector pin.
Caveats & Gotchas
- • Because this is the Blueprint autocast, connecting a Rotator wire to a Vector input in Blueprint silently calls this function — be aware when porting Blueprint logic to C++ that a Rotator-to-Vector wire does not pass all three angle components, only the forward direction.
- • The function discards Yaw entirely for the Z-component calculation — the resulting Z equals sin(-Pitch), so two rotators with the same Pitch but different Yaw produce vectors with identical Z but different XY.
