UKismetMathLibrary::Vector4_Zero

function Engine Blueprint Since 4.0

#include "Kismet/KismetMathLibrary.h"

Access: public Specifiers: staticUFUNCTIONBlueprintPure

Description

Returns the FVector4 zero constant (0, 0, 0, 0). Primarily exposed so Blueprint and Python scripts can access the constant without manual construction.

Caveats & Gotchas

• In C++ prefer FVector4(ForceInitToZero) or FVector4(0,0,0,0) directly — the function call is unnecessary even if the compiler inlines it.
• The header comment incorrectly reads '(0,0,0)'; all four components including W are zeroed.

Signature

static UE_INL_API FVector4 Vector4_Zero();

Return Type

FVector4

Example

Reset a Vector4 accumulator before summing C++

FVector4 Accumulator = UKismetMathLibrary::Vector4_Zero();
for (const FVector4& Sample : Samples)
    Accumulator += Sample;
