Swep functions to NPC

[Angry pepper]

I'm currently working on a combine guard SNPC and require information on how to turn a swep function from the strider cannon into a an NPC function...
I'm no genius on functions, but this is what i've gathered...

function SWEP:ShootCannon()

	if not self.Charging then return end
	if not self.Weapon or not self.Weapon:IsValid() then return end
	if not self.Owner or not self.Owner:Alive() then return end

	local PlayerPos = self.Owner:GetShootPos() 
	local tr = self.Owner:GetEyeTrace()
	
	local dist = (tr.HitPos - PlayerPos):Length()
	local delay = dist/8000
	
	self:TakeSecondaryAmmo(1)
	
	self.Weapon:EmitSound(self.Cannon.ShootSound)
	
	local fx = EffectData()
	fx:SetEntity(self.Owner)
	fx:SetOrigin(tr.HitPos)
	fx:SetAttachment(1)
	util.Effect("stridcan_fire",fx)
	util.Effect("stridcan_mzzlflash",fx)
	
	--play animations
	self.Weapon:SendWeaponAnim(ACT_VM_PRIMARYATTACK)
	self.Owner:MuzzleFlash()
	self.Owner:SetAnimation(PLAYER_ATTACK1)
	
	--apply recoil
	self.Owner:ViewPunch( Angle(math.Rand(-0.2,-0.1)*self.Cannon.Recoil,math.Rand(-0.1,0.1)*self.Cannon.Recoil, 0))
	
	timer.Simple(delay,self.Disintegrate,self,tr)
	
	self.Charging = false

end

No, don't just copy paste code from other addons like the beta swep pack to a single half working entity and call it your work.

This is an easy function, build it yourself and if you can't do that start with something simpler than an SNPC.
