This is a fairly quick way to do it by using variables and random.

Code: Select all

local lat = '23.8611'
local lon = '-131.8288'
math.randomseed(os.time())

--ADD CARRIER
ScenEdit_AddUnit({type='Ship', name='George Bush', heading =0, dbid =3225, side ='USA', Latitude=lat,Longitude=lon, altitude="0 ft", speed=0,proficiency=4})

--ADD Support ship
ScenEdit_AddUnit({type='Ship', name='Henry J. Kaiser 187', heading =180, speed=0, dbid =26, side ='USA', Latitude=((math.random(10)/10)+lat+.020),Longitude=((math.random(5)/5)+lon-0.10), altitude="0 ft",proficiency=4})

--ADD Submarine SSN 700 Dallas [Los Angeles Class] 2008
ScenEdit_AddUnit({type='Submarine', name='USS Chicago', heading =0, speed=0, dbid =533, side ='USA', Latitude=((math.random(10)/10)+lat+0.30),Longitude=((math.random(6)/6)+lon+0.11), altitude="-300 ft",proficiency=3})

Thank you! Not just optimal for what i have in mind. The plan is to have the USS Chicago 5 nm 0 degree in front of the carrier, Ticonderoga also front then Arleigh Burke classes on 45, 135, 225, 315 degrees from the Carrier with a distance around 6 nm from carrier and two Support ships just behind...

But would this work ...
1. Add the units in a bunch.
2. Then set the formation detail of each unit in the group giving the distance/bearing of the units from the group lead with the flag to jump to the location.

Note that the 'transpose' option is not in the latest build - it was missing. Currently it would place the formation marker but the ship would move there. Once the 'transpose' option is in place, it will teleport to the location.

Code: Select all

--CVN 77 GEORGE BUSH - (mothership)
ScenEdit_AddUnit({type='Ship', name='George Bush', heading =0, dbid =3225, side ='blue', Latitude='N69.00.00',Longitude='E10.00.00', altitude='0 ft', speed=20,proficiency=4, group = "CVN TG"})

--ADD DDG 96 BAINBRIDGE AND 2 x Lynx (one of the 8 ship around George Bush)
local u = ScenEdit_AddUnit({type='Ship', name='Bainbridge', heading =0, speed=20, dbid =2873, side ='blue', heading =0, speed=0, altitude=0, proficiency=4, Latitude='N69.00.00',Longitude='E10.00.00', group = "CVN TG"})

u.formation = {type='rotating', bearing=315, distance=7, transpose=true} -- station = relative bearing 315 deg at 7 NM from lead

Naah i see that you use lat and lon for bainbridge, that is what i trying to avoid. I want a code so i just need to change the carriers coordinates and all the ships will move to location relativeTo the carrier.

Use the carrier latitude,longitude with the method GetPointFromBearing to get the latitude/longitude of the other ships

You don't need to create a RP. You store your carrier in a variable an with GetPointFromBearing you can get the ddg position with your cv position, bearing and distance as desired. Hope it helps
