focusedBlock.CFrame = focusedBlock.CFrame:lerp(CFrame.new(focusedBlock.CFrame + Vector3(0, blockVelocity.x, blockVelocity.y)), smoothing / 2)
Where as FocusedBlock is instance
Smoothing is number for the lerp (I get it from attribute)
And blockVelocity is vector2 of the mouse delta multiplied by sensitivity
