UKismetMathLibrary::GetForwardVector

function Engine Blueprint Since 4.0

#include "Kismet/KismetMathLibrary.h"

Access: public Specifiers: staticUFUNCTIONBlueprintPure

Description

Returns the world-space unit vector pointing in the forward (X+) direction for the given rotation. Identical to rotating FVector::ForwardVector by InRot.

Caveats & Gotchas

• The returned vector is already normalized (unit length). Do not call Normalize() on the result — it's a no-op at best and can introduce floating-point error.
• If InRot comes from GetActorRotation() on an actor whose RootComponent has a non-identity relative rotation, this may not match the component's actual forward — use USceneComponent::GetForwardVector() instead in that case.

Example

Spawn a projectile in the actor's forward direction C++

FVector Forward = UKismetMathLibrary::GetForwardVector(GetActorRotation());
FVector SpawnPos = GetActorLocation() + Forward * 100.f;
World->SpawnActor<AMyProjectile>(SpawnPos, GetActorRotation());
