UKismetMathLibrary::GetBoxSize

function Engine Blueprint Since unknown

#include "Kismet/KismetMathLibrary.h"

Access: public Specifiers: staticUFUNCTIONBlueprintPure

Description

Returns the full width, depth, and height of an axis-aligned box as a vector (Max - Min on each axis).

Caveats & Gotchas

• Exposed to Blueprint as "Get Size (Box)" via a DisplayName meta tag rather than the raw function name.
• This returns the full size, not the half-extent used by functions like IsPointInBox — dividing by 2 gives the extent if you need it.
