UKismetMathLibrary::Add_VectorVector

function Engine Blueprint Since 4.0

#include "Kismet/KismetMathLibrary.h"

Access: public Specifiers: staticUFUNCTIONBlueprintPure

Description

Adds two vectors component-wise, returning a new FVector. This is the Blueprint '+' operator for vectors and the most common way to offset a position or accumulate a direction.

Caveats & Gotchas

• Component-wise addition does not preserve vector length — if you need to combine directions and maintain a unit vector, normalize the result afterward.
• In Blueprint the node appears as 'vector + vector' with a compact '+' title; both inputs are displayed as a single pin cluster, which can obscure which vector is A and which is B when reading graphs.

Signature

static UE_INL_API FVector Add_VectorVector(FVector A, FVector B);

Parameters

Name	Type	Description	Default
A	FVector	The first vector.	—
B	FVector	The second vector to add.	—

Return Type

FVector

Example

Offset actor position by a delta C++

FVector CurrentPos = MyActor->GetActorLocation();
FVector Delta = FVector(0.f, 0.f, 100.f);
FVector NewPos = UKismetMathLibrary::Add_VectorVector(CurrentPos, Delta);
MyActor->SetActorLocation(NewPos);
