Hello,
I want to make a vehicle that releases drones when enemy is near. I wanted to add special inventory for drones.

	if ent.name == "sf-reaver" and not ent.scarabey then
		ent.scarabey=0
	end

it says

LuaEntity doesn't contain key scarabey.

How to add a new atribute?

Store it in global table:

if not global.vehicles then
  global.vehicles = {}
end
global.vehicles[entity.unit_number] = {entity=entity, scarabey=scarabey}

Then you can call it from global table:

local scarabey = global.vehicles[entity.unit_number].scarabey
