UKismetMathLibrary::Vector_Down

function Engine Blueprint Since 4.0

#include "Kismet/KismetMathLibrary.h"

Access: public Specifiers: staticBlueprintPure

Description

Returns the Unreal Engine world down direction constant (0, 0, -1), the -Z axis.

Caveats & Gotchas

• Identical to negating Vector_Up(). Both are valid; choose based on readability.
• Default gravity acts along this axis, but if you have changed the gravity direction in your physics scene, this constant will NOT match the actual gravity vector. Query the physics scene directly in that case.
