[LUA Question] Add a delay

Hey guys, I have this entity spawner here, it works good but I wish to add a 1 minute delay before it spawns a next zombie.



                            if self.Count < self.MaxSpawnable then
                                  -- Insert 1 minute delay here
				  local ent = ents.Create(self.SpawnEntity)
                                    if ent and ent:IsValid() then
                                    ent:SetPos(self:GetPos())
				   ent:SetModel("models/zed/malezed_0"..table.Random( {4, 6, 8} )..".mdl")
                                    ent:Spawn()
                                    end
                                   
                                    if not ent:IsInWorld() then ent:Remove() end
                                    self.Count = self.Count + 1
                                    table.insert(self.SpawnedNPCs,ent)
                            end   


Thanks :smiley:
