Getting the hang of the LUA, except for when adding magazines to an airfield/airport...

Just when I thought I got it right by adding a missing comma, I receive the message, "ScenEdit_AddWeaponToUnitMagazine ,0 : No Weapon Defined". How exactly do I define it? Could you help me with this? Thanks.

From Lua Docs:
ScenEdit_AddWeaponToUnitMagazine({unitname='Ammo', w_dbid=773, number=1, w_max=10})

Example from one of my early tests - should give you an idea
-- get the magazines on the unit
local unit = {name='CVN 70 Carl Vinson [Nimitz Class]', guid='e0ad9db3-730b-45e5-8c45-2daa8f08a419'}
local mags = ScenEdit_GetUnit({name=unit.name, guid=unit.guid}).magazines
local mag_guid = ''
local mag_items = {}
-- find the one to fillout
for k,v in pairs(mags) do
if v.mag_name == 'Carrier Magazine' then
mag_guid = v.mag_guid
print(v.mag_name)
mag_items = v.mag_weapons
break
end
end
local count = 0
--print(mag_items)
-- update each weapon in the magazine
for k,v in pairs(mag_items) do
print(v)
-- fillout the magazine weapon
-- local resp = ScenEdit_AddWeaponToUnitMagazine({guid=unit.guid, mag_guid=mag_guid , wpn_dbid=v.wpn_dbid, fillout=true})
-- add 10 to the magazine weapon
local resp = ScenEdit_AddWeaponToUnitMagazine({guid=unit.guid, mag_guid=mag_guid , wpn_dbid=v.wpn_dbid, number=10})
count = count + resp
end
print('Added = ' .. count)

And where can I find the wpn_guid? As it seems to be something of a key thing to consider here...

So, if I understand this...

The Magazine (like Airport or Carrier Magazine) is identified at the top first? Before the rest of the command comes in?

Yes, you would have a unit -> which will may have one or more magazines -> which each may have one or more weapon slots.

Easiest way is to create the INI file from the scenario. It should have this information.
The other way is to use Lua and dump out the magazine data as shown in the above example.

the guid is not something you need to worry about - it is created automatically when you add something, it is listed after he added it in. The w_DBID is important - those need to come from the weapons DB.
