Just how exactly would I make iron sights for a swep? Searching is disabled by the way so i can't search.

You first need the code that does it. You can either inherit from a base (Such as weapon_cs_base which everyone has) or put the code in yourself. (This is a straight rip from weapon_cs_base incidentally)

local IRONSIGHT_TIME = 0.25

/*---------------------------------------------------------
   Name: GetViewModelPosition
   Desc: Allows you to re-position the view model
---------------------------------------------------------*/
function SWEP:GetViewModelPosition( pos, ang )

	if ( !self.IronSightsPos ) then return pos, ang end

	local bIron = self.Weapon:GetNetworkedBool( "Ironsights" )
	
	if ( bIron != self.bLastIron ) then
	
		self.bLastIron = bIron 
		self.fIronTime = CurTime()
		
		if ( bIron ) then 
			self.SwayScale 	= 0.3
			self.BobScale 	= 0.1
		else 
			self.SwayScale 	= 1.0
			self.BobScale 	= 1.0
		end
	
	end
	
	local fIronTime = self.fIronTime or 0

	if ( !bIron && fIronTime < CurTime() - IRONSIGHT_TIME ) then 
		return pos, ang 
	end
	
	local Mul = 1.0
	
	if ( fIronTime > CurTime() - IRONSIGHT_TIME ) then
	
		Mul = math.Clamp( (CurTime() - fIronTime) / IRONSIGHT_TIME, 0, 1 )
		
		if (!bIron) then Mul = 1 - Mul end
	
	end

	local Offset	= self.IronSightsPos
	
	if ( self.IronSightsAng ) then
	
		ang = ang * 1
		ang:RotateAroundAxis( ang:Right(), 		self.IronSightsAng.x * Mul )
		ang:RotateAroundAxis( ang:Up(), 		self.IronSightsAng.y * Mul )
		ang:RotateAroundAxis( ang:Forward(), 	self.IronSightsAng.z * Mul )
	
	
	end
	
	local Right 	= ang:Right()
	local Up 		= ang:Up()
	local Forward 	= ang:Forward()
	
	

	pos = pos + Offset.x * Right * Mul
	pos = pos + Offset.y * Forward * Mul
	pos = pos + Offset.z * Up * Mul

	return pos, ang
	
end


/*---------------------------------------------------------
	SetIronsights
---------------------------------------------------------*/
function SWEP:SetIronsights( b )

	self.Weapon:SetNetworkedBool( "Ironsights", b )

end


SWEP.NextSecondaryAttack = 0
/*---------------------------------------------------------
	SecondaryAttack
---------------------------------------------------------*/
function SWEP:SecondaryAttack()

	if ( !self.IronSightsPos ) then return end
	if ( self.NextSecondaryAttack > CurTime() ) then return end
	
	bIronsights = !self.Weapon:GetNetworkedBool( "Ironsights", false )
	
	self:SetIronsights( bIronsights )
	
	self.NextSecondaryAttack = CurTime() + 0.3
	
end

/*---------------------------------------------------------
	DrawHUD
	
	Just a rough mock up showing how to draw your own crosshair.
	
---------------------------------------------------------*/
function SWEP:DrawHUD()

	// No crosshair when ironsights is on
	if ( self.Weapon:GetNetworkedBool( "Ironsights" ) ) then return end

	local x = ScrW() / 2.0
	local y = ScrH() / 2.0
	local scale = 10 * self.Primary.Cone
	
	// Scale the size of the crosshair according to how long ago we fired our weapon
	local LastShootTime = self.Weapon:GetNetworkedFloat( "LastShootTime", 0 )
	scale = scale * (2 - math.Clamp( (CurTime() - LastShootTime) * 5, 0.0, 1.0 ))
	
	surface.SetDrawColor( 0, 255, 0, 255 )
	
	// Draw an awesome crosshair
	local gap = 40 * scale
	local length = gap + 20 * scale
	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 )

end

/*---------------------------------------------------------
	onRestore
	Loaded a saved game (or changelevel)
---------------------------------------------------------*/
function SWEP:OnRestore()

	self.NextSecondaryAttack = 0
	self:SetIronsights( false )
	
end

After you have somehow got that in your swep, you need to define your ironsights data. This is different between each weapon. For instance for the model 'models/weapons/v_pist_fiveseven.mdl' you would use this:

SWEP.IronSightsPos = Vector (4.5313, -0.8637, 3.2683)
SWEP.IronSightsAng = Vector (-0.088, -0.1113, 0)

The easiest and quickest way to get this is by using this wonderful addon, which is pretty much self explanatorty.

Have fun!

I'm getting a constant error and I don't know how to fix it. The iron sights worked though.

Show us line 201 in shared.lua, my best guess is that self.Primary.Cone isn't defined.

Also, penis.jpg ... wtf

[mescool15]

Hold on, Some asshole uninstalled Notepad ++ off my computer.

EDIT: Here it is. local scale = 10 * self.Primary.Cone

You need to define SWEP.Primary.Cone outside of any function.

SWEP.Primary.Cone = 0.02 --This is how accurate your gun is, a cone of 0 is completely accurate, a cone of 1 is horribly accurate
