From Weapons to Entities

[LouieTien]

So recently I bought this script from coderhire called "NPC Gun Dealer w. Robbery" which is obviously a NPC gun dealer that can be robbed.
But it only sells guns. So what I need help with is changing it from weapons to entities, like so instead of placing weapons there, I want to place entities such as food and maybe printers to replace the F4 tab.

Please help :)

Heres some of the init.lua (Not publishing the whole thing so it's basicly leaked)

[function ENT:SpawnFunction( ply, tr )

if ( !tr.Hit ) then return end

local SpawnPos = tr.HitPos + tr.HitNormal * 16

	npc2 = ents.Create( "npc" )
	npc2:SetPos( SpawnPos )
	npc2:Spawn()
	npc2:Activate()

return ent

end


function ENT:Initialize()
	self:SetModel("models/odessa.mdl")
	self:SetHullType(HULL_MEDIUM)
	self:SetHullSizeNormal()
	self:SetNPCState(NPC_STATE_SCRIPT)
	self:CapabilitiesAdd(CAP_TURN_HEAD)
	self:SetSolid(SOLID_BBOX)
	self:SetUseType(SIMPLE_USE)
	self:DropToFloor()
	selfEnt = self
	self:SetMaxYawSpeed(90)
end
 
function ENT:OnTakeDamage(dmg)
end

function ENT:AcceptInput( Name, Activator, Caller )
	if Name == "Use" and Caller:IsPlayer() then
	if self.Busy then
	Caller:SendLua(
	[[
	chat.AddText( Color(0,200,0), "[NPC SHOP]", Color(255,255,255, 255)," Call the cops, i'm being robbed!")]])
	return end
		umsg.Start("convobox", Caller)
		umsg.End()
		end
		local weapon = Caller:GetActiveWeapon()
		if weapon:Clip1() < 1 then return end
 		if Name == "Use" and weapon:IsValid() then
		umsg.Start("Robbery", Caller)
		umsg.Entity(self)
		umsg.Bool(self.Robbing)
		umsg.End()
	end
end
