Using SWEP:AdjustMouseSensitivity()

[A Fghtr Pilot]

Hello. So, for a sniper rifle SWEP I'm making, I've been trying to get SWEP:AdjustMouseSensitivity() to make the sensitivity lower when a player is scoping in with their weapon(code ahead), but I've had no luck. This is my current code for the whole SWEP:

AddCSLuaFile()

	--General
SWEP.Base					= "dm_baseweapon"
SWEP.Spawnable				= true
SWEP.AdminSpawnable			= true
SWEP.Category				= "The CyBorg SWEPs"
SWEP.PrintName				= "SteyrScout"

	--View Model
SWEP.ViewModelFOV 			= 52
SWEP.ViewModel				= "models/weapons/cstrike/c_snip_scout.mdl"
SWEP.ViewModelFlip			= false
SWEP.UseHands				= true

	--World Model
SWEP.WorldModel				= "models/weapons/w_snip_scout.mdl"
SWEP.HoldType				= "ar2"

	--Primary
SWEP.Primary.FireSound		= "Weapon_Scout.Single"
SWEP.Primary.NumShots		= 1
SWEP.Primary.Damage			= 50
SWEP.Primary.Recoil			= 4
SWEP.Primary.Spread			= 0.01
SWEP.Primary.Delay			= 1.40

SWEP.Primary.ClipSize		= 10
SWEP.Primary.DefaultClip	= 50
SWEP.Primary.Automatic		= false
SWEP.Primary.Ammo			= "ar2"

	--Secondary
SWEP.Secondary.ClipSize		= -1
SWEP.Secondary.DefaultClip	= -1
SWEP.Secondary.Automatic	= false
SWEP.Secondary.Ammo			= "none"

function SWEP:Initialize()

self:SetHoldType( "ar2" )

self:SetNWBool( "Scoping", false )

end

function SWEP:SetScoping( b )

self.Weapon:SetNWBool( "Scoping", b )

end

SWEP.SprintPos = Vector(1.52, 0, 0.959)
SWEP.SprintAng = Vector(-9.146, 4.925, 0)

function SWEP:SetZoom(state)
    if CLIENT then
       return
    elseif IsValid(self.Owner) and self.Owner:IsPlayer() then
       if state then
          self.Owner:SetFOV(10, 0.3)
       else
          self.Owner:SetFOV(0, 0.2)
       end
    end
end

if CLIENT then
   local scope = surface.GetTextureID("sprites/scope")
   function SWEP:DrawHUD()
      if self:GetNWBool( "Scoping" ) == true then
         surface.SetDrawColor( 0, 0, 0, 255 )

         local x = ScrW() / 2.0
         local y = ScrH() / 2.0
         local scope_size = ScrH()

         -- crosshair
         local gap = 80
         local length = scope_size
         surface.DrawLine( x - length, y, x - gap, y )
         surface.DrawLine( x + length, y, x + gap, y )
         surface.DrawLine( x, y - length, x, y - gap )
         surface.DrawLine( x, y + length, x, y + gap )

         gap = 0
         length = 50
         surface.DrawLine( x - length, y, x - gap, y )
         surface.DrawLine( x + length, y, x + gap, y )
         surface.DrawLine( x, y - length, x, y - gap )
         surface.DrawLine( x, y + length, x, y + gap )


         -- cover edges
         local sh = scope_size / 2
         local w = (x - sh) + 2
         surface.DrawRect(0, 0, w, scope_size)
         surface.DrawRect(x + sh - 2, 0, w, scope_size)

         surface.SetDrawColor(255, 0, 0, 255)
         surface.DrawLine(x, y, x + 1, y + 1)

         -- scope
         surface.SetTexture(scope)
         surface.SetDrawColor(255, 255, 255, 255)

         surface.DrawTexturedRectRotated(x, y, scope_size, scope_size, 0)

      else
         return
      end
   end
end

function SWEP:Reload()

self:DefaultReload( ACT_VM_RELOAD )
self:SetScoping( false )
self:SetZoom( false )

end

function SWEP:Holster()
    self:SetScoping(false)
    self:SetZoom(false)
    return true
end

--Secondary Attack Function

function SWEP:SecondaryAttack()

local bScope = not self:GetNWBool( "Scoping", false )

self:SetScoping( bScope )

    if SERVER then
        self:SetZoom(bScope)
     else
        self:EmitSound("Default.Zoom")
    end

self:SetNextSecondaryFire( CurTime() + 0.3)
	
end

Yes, I did borrow some code from TTT's rifle but that's not the point. How would I go about making AdjustMouseSensitivity only adjust the mouse sensitivity when you're scoping in?

Just use this thing I made:

function SWEP:AdjustMouseSensitivity()
	if ( !self:GetZoom() ) then return nil end
    return self.Owner:GetFOV() / GetConVarNumber( "fov_desired" ) / 2
end

Don't forget to add SWEP:GetZoom() function clientside.

Thanks! it works perfectly.

function SWEP:AdjustMouseSensitivity()
	if ( !self:GetNWBool( "Scoping" ) ) then return nil end
	return self.Owner:GetFOV() / GetConVarNumber( "fov_desired" ) / 2
end
