Gather all units of single type in a list? - 12/6/2020 3:59:09 AM

Hi all,

Just getting started with Lua scripting and CMO in general. I have experience with Python.

I'm wondering if there's a function or straightforward 'for' loop that will access all units on a side of type 'Surface Ship.' I have a scenario where I've placed a ton of random commercial merchant traffic and I'm looking to go through them and assign home bases and/or random headings. Obviously, the intent is to litter the area with random sea traffic, but I'm not sure that most straightforward way of automating this. Thanks!

Yes, that's difficult because generally you need to know a unit's name or guid ahead of time in order to GetUnit.

What I do, following others, is to create units directly in LUA and list them in a table as they are created in order to keep track of them. EX:

quote:

function AddFingerFour(callsign,side,dbid,loadout,latitudeIn,longitudeIn,heading,altitude,proficiency,groupName)
--local circle = World_GetCircleFromPoint({latitude=latitude,longitude=longitude,radius=0.5,numpoints = 72})
local addedAircraftTable = {}

blah blah blah

local unit = ScenEdit_AddUnit({type='Aircraft',side=side,dbid=dbid,name=callsign..' #'..i,loadoutid=loadout,latitude=position.latitude,longitude=position.longitude,heading=heading,altitude=altitude,proficiency=proficiency});
unit.group=groupName
table.insert(addedAircraftTable,unit)

return addedAircraftTable
end

Then the loop to access each unit:

quote:

for key, value in pairs(addedAircraftTable) do

blah blah blah

Yes. Get the side wrapper, grab the unitlist by using unitsBy('Ship') method;

local s = VP_GetSide({side="Red"});
local tbl = s:unitsBy('Ship'); --All surface ships
--local tbl2 = s:unitsBy('Ship','2002'); --example to further constrained to Surface Combatant
--local tbl3 = s:unitsBy('Ship',nil,'2008'); --example to constrain to CVN sub-type's only
local u; --unit wrapper
local retval = false; --return value from pcall
for k,v in pairs(tbl) do
  retval,u = pcall(ScenEdit_GetUnit,{guid=v.guid}); --suppress errors.
  if (retval == true) and u ~=nil then
     --Do Stuff You want with each unit.
     print(string.format("Unitname: %s  Lat: %s Lon: %s",tostring(u.name),tostring(u.latitude),tostring(u.longitude)));
     --
  else
    print('Could not obtain unit. err: ' .. tostring(u)); --u contains error msg if retval is false.
  end
  retval,u = false,nil;
end
