Testing to See if Loadout is Set

[SeaQueen]

In order to make an improved version of my aircraft maintenance script, I'm experimenting with using the function

Code: Select all

ScenEdit_GetLoadout (loadoutinfo)

to test whether or not the loadout has been set or not. This should hopefully allow me to retain loadouts between save games without the risk of resetting unintentionally. I've run into a little problem, though. Instead of returning nil, 0, 99999 or some other useful value when the aircraft's loadout isn't set, I get an error message.

Has anyone encountered a similar problem? Is there a work around or solution?

example of script or test save?

SeaQueen,
I presume you mean if you call GetLoadout({UnitName='somebasedaircraft1',LoadoutID=0}) on an aircraft who's loadout is unassigned? Doing it in console regularly will throw a object ref not set normally.

The trick\workaround is to wrap the GetLoadout call around setting the Tool_EmulateNoConsole() setting to true, as when it's true the error is suppressed and the return value will be nil and check-able, as it does when run under an event or special action context as well, just not in the console.

From some fragment I had related to this:

Code: Select all

 -- Returns true on having loadout, false on nil or error, prints debug info
 local function HasLoadout(u)
     local ltext= 'empty';
     local retval= false;
     if u ~= nil then
         print('unit: ' .. tostring(u.name));
         Tool_EmulateNoConsole(true);
         local l = ScenEdit_GetLoadout({UnitName=u.name,LoadoutID=0}); --request current assigned loadout
         Tool_EmulateNoConsole(false);
         if l ~=nil then
             ltext= tostring(l.dbid);
             retval= true;
         else
             ltext= 'No Loadout';
         end
     else
         print('Invalid Unit');
     end
     print('LoadoutID: ' .. ltext);
     ltext = nil;
     return retval;
 end
 
 local unit1 = ScenEdit_GetUnit({name='Raptor99', guid='d20fea11-f966-4d7d-a0c5-9c8dafa02db0'});  --in the air with loadout
 local unit2 = ScenEdit_GetUnit({name='TestAircraft #1'});  --at base with no loadout assigned
 HasLoadout(unit1);
 HasLoadout(unit2);
 
 

--Result with EmulateNoConsole disabled
--unit: Raptor99
--LoadoutID: 4523
--unit: TestAircraft #1
--ERROR: Object reference not set to an instance of an object.

--Result with above code (using EmulateNoConsole set to true temporarily).
--unit: Raptor99
--LoadoutID: 4523
--unit: TestAircraft #1
--LoadoutID: No Loadout

I agree it would be an improvement if nil were returned in both cases.

Perfect!
