How to add RunSights?

[MinerBoy004]

I can't seem to figure out how to add RunSights to a SWEP that I am making. Any help? I try to ask my friend but he always says he is busy but he knows how.
Thanks for the help. :D (If any.)

Code that I have so far:

SWEP.RunSightsPos = Vector(0, 0, 6.377)

SWEP.RunSightsAng = Vector(-26.181, 0, 0)


function SWEP:GetViewModelPosition(pos, ang)

	if SERVER then return Vector(0,0,0), Angle(0,0,0) end

--reposition the weapon when you run, adding more realism to the base.

    local RunPos = self.RunSightsPos

    local RunAng = self.RunSightsAng

    

    if RunAng then

        ang = ang * 1

        ang:RotateAroundAxis (ang:Right(),         RunAng.x)

        ang:RotateAroundAxis (ang:Up(),         RunAng.y)

        ang:RotateAroundAxis (ang:Forward(),     RunAng.z)

    end



    if RunPos then

        local Right     = ang:Right()

        local Up         = ang:Up()

        local Forward     = ang:Forward()

    

        pos = pos + RunPos.x * Right

        pos = pos + RunPos.y * Forward

        pos = pos + RunPos.z * Up

    end
