UKismetMathLibrary::FClamp
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticBlueprintPureUFUNCTION
Description
Returns Value clamped to the range [Min, Max] inclusive. The Blueprint node defaults show 0.0–1.0 but any range is valid.
Caveats & Gotchas
- • If Min > Max the behavior is undefined (FMath::Clamp asserts in Debug builds) — always ensure Min <= Max before calling.
- • The Blueprint node metadata sets default display values of 0..1, which can mislead users into thinking this is alpha-only — the actual range accepted is any valid double.
