This sample code shows how to attach custom sights meshes into a Weapon and work as real scopes.
-- Spawning the AK47
local my_ak47 = NanosWorldWeapons.AK47(Vector(1035, 154, 300), Rotator())
-- Adds a StaticMesh Attached with a RedDot mesh into AK47 on sight_socket bone from AK47 model. As our AK47 model already
-- have a bone named sight_socket at the right location, we can just attach to it, otherwise we would
-- need to set it's Attach Location to where the RedDot fits and using bone name as empty ""
my_ak47:AddStaticMeshAttached("sight", "nanos-world::SM_T4_Sight", "sight_socket")
-- Makes the FOV multiplier reduces by 0.35x when ADS (aiming)
my_ak47.SightFOVMultiplier = 0.35
-- Sets the ADS transform offset to fit the RedDot center position,
-- each weapon will need a different offset to fit it's sight. AK47 + RedDot best fit is Z = -15.9
my_ak47:SetSightTransform(Vector(0, 0, -15.9), Rotator(0, 0, 0))
