Specifiers: staticBlueprintPureUFUNCTION
Description
Returns the constant FVector2D (1, 1). Useful as a multiplicative identity or as a uniform scale factor of 1 in 2D operations.
Caveats & Gotchas
- • This is NOT a unit vector — its magnitude is sqrt(2) ≈ 1.414. Use Vector2D_Unit45Deg if you need a normalised diagonal vector.
- • Primarily useful in Blueprint where a literal (1,1) constant node is less ergonomic; in C++ prefer FVector2D::UnitVector or FVector2D(1.0, 1.0) directly.

FVector2D Example
Reset a 2D scale to identity C++
FVector2D Scale = UKismetMathLibrary::Vector2D_One();
// Scale == (1.0, 1.0)Tags
