UKismetMathLibrary::NotEqualExactly_Vector2DVector2D

function Engine Blueprint Since 4.0

#include "Kismet/KismetMathLibrary.h"

Access: public Specifiers: staticUFUNCTIONBlueprintPure

Description

Returns true if A and B are not bit-exactly equal. The inverse of EqualExactly_Vector2DVector2D — use sparingly for the same reasons.

Caveats & Gotchas

• Like EqualExactly, this performs a bitwise comparison. Two conceptually equal vectors computed via different paths will almost always be considered not-equal due to floating-point imprecision.
• For most inequality checks, NotEqual_Vector2DVector2D with a tolerance is the correct choice.

Signature

static UE_INL_API bool NotEqualExactly_Vector2DVector2D(FVector2D A, FVector2D B);

Parameters

Name	Type	Description	Default
A	FVector2D	The first vector.	—
B	FVector2D	The second vector.	—

Return Type

bool

Example

Detect any change to a cached position C++

FVector2D CachedPos = LastKnownPos;
// ... some logic that may or may not modify LastKnownPos ...
bool bChanged = UKismetMathLibrary::NotEqualExactly_Vector2DVector2D(LastKnownPos, CachedPos);
