UKismetMathLibrary::Vector_GetAbsMax

function Engine Blueprint Since 4.0

#include "Kismet/KismetMathLibrary.h"

Access: public Specifiers: staticUFUNCTIONBlueprintPure

Description

Returns the largest absolute value among the three components of a vector: max(|X|, |Y|, |Z|). Useful for finding the dominant axis regardless of sign, or computing the Chebyshev (L-infinity) norm.

Caveats & Gotchas

• The return value is always non-negative, even if all components of the input are negative.
• Unlike GetMaxElement, this uses absolute values — a vector of (-100, 5, 3) returns 100, not 5.
• This gives the L-infinity (Chebyshev) norm, not the Euclidean length. Don't confuse it with Size() or SizeSquared().

Parameters

Name	Type	Description	Default
A	FVector	The vector to inspect.	—

Return Type

double

Example

Find the most significant component offset C++

FVector Delta = TargetPos - CurrentPos;
double LargestChange = UKismetMathLibrary::Vector_GetAbsMax(Delta);
// LargestChange is the biggest single-axis displacement, ignoring sign
