UKismetMathLibrary::GetAbsMax2D

function Engine Blueprint Since 4.0

#include "Kismet/KismetMathLibrary.h"

Access: public Specifiers: staticBlueprintPure

Description

Returns the largest absolute value among the vector's X and Y components. Useful for determining the dominant axis regardless of sign.

Caveats & Gotchas

• Returns a scalar, not a vector — it does not tell you which component was dominant. Use GetMax2D if you need the signed maximum.
• On a zero vector the result is 0.0, which is well-defined but may need guarding if you intend to divide by this value.

Signature

static UE_INL_API double GetAbsMax2D(FVector2D A);

Parameters

Name	Type	Description	Default
A	FVector2D	Input 2D vector.	—

Return Type

double

Example

Scale a velocity so its dominant axis stays within a limit C++

FVector2D Velocity = FVector2D(-120.f, 45.f);
double MaxComponent = UKismetMathLibrary::GetAbsMax2D(Velocity); // 120
if (MaxComponent > 100.0)
    Velocity *= 100.0 / MaxComponent;
