Grouping units

[Gunner98]

Hay guys

Building a base on the AI side. This will happen at a certain point where a single unit airfield on a neutral side will be replaced by a multiple unit base on a bad guy side. I want it so the player can attack it if he does so before it is too heavily defended.

No issues adding all the units, that all works. Question is how do I group the units into a base?

I am away from my computer right now but I do unit and group creation like the linked example on the Lua got hub. http://commandlua.github.io/examples/sc ... t.lua.html

[Gunner98]

OK - never saw this example before, right there in front of me. Thanks

[Gunner98]

OK Just able to get back to this now:

Getting an error:
ERROR: [string "Console"]:32: '}' expected (to close '{' at line 26) near 'for'

Played around with it for a while but no joy - any ideas?

There seems to be a missing '}' at the ends of the {unit=........}. They should be 'one block'
E.g.

{unit=
{
type = 'Facility', name = 'Maribor main Runway', heading = 120, dbid = 55, side = 'Hugary', latitude='46.4803890511425', longitude='15.6878028852709'
}
},

Actually there are a few things wrong. Let me drop in a full updated version

[michaelm75au]

You forgot the index to the newUnits table. You may have done it when pasted but '[ i ]' means italic in the posting[:D]
The other thing is that if you want to assign the units to a group, you need to do so in the 'unit=' as shown.

Attached the code as a file as the I forgot the post formatting kills it.

[Whicker]

That example is sort of complex, the important part of adding a unit to a group is simply to set the units group value to the name of the group:

local u = SE_GetUnit({blah blah})
u.group="that big group"

I played around with making an air base via a lua function, it worked pretty well:

function W_CreateAirBase(basename,side,latlonTable, runways, taxiways, accesspoints, tarmacspaces, hangers, ammopads,detectable)
local lat=latlonTable['latitude']
local lon=latlonTable['longitude']
for i=1,runways do
local u = ScenEdit_AddUnit({side=side, type='Facility', name='Runway '..i, dbid=55, autodetectable=detectable, Lat=lat, Lon=lon})
u.group =basename
lat=lat +.004
end --runways

lat=latlonTable['latitude'] --reset lat and add to lon

lon=latlonTable['longitude'] + .002
for i=1,taxiways do
local u = ScenEdit_AddUnit({side=side, type='Facility', name='Taxiway '..i, dbid=1424, autodetectable=detectable, Lat=lat, Lon=lon})
u.group =basename
lat=lat +.004
end
lat=latlonTable['latitude'] --reset lat and add to lon

lon=latlonTable['longitude'] + .004
for i=1,accesspoints do
local u = ScenEdit_AddUnit({side=side, type='Facility', name='Access Point '..i, dbid=353, autodetectable=detectable, Lat=lat, Lon=lon})
u.group =basename
lat=lat +.002
end
lat=latlonTable['latitude'] --reset lat and add to lon

lon=latlonTable['longitude'] + .006
for i=1,tarmacspaces do
local u = ScenEdit_AddUnit({side=side, type='Facility', name='Tarmac Space '..i, dbid=344, autodetectable=detectable, Lat=lat, Lon=lon})
u.group =basename
lat=lat +.002
end
lat=latlonTable['latitude'] --reset lat and add to lon

lon=latlonTable['longitude'] + .008
for i=1,ammopads do
local u = ScenEdit_AddUnit({side=side, type='Facility', name='Ammo Pad '..i, dbid=1496, autodetectable=detectable, Lat=lat, Lon=lon})
u.group =basename
lat=lat +.002
end

lon=latlonTable['longitude'] - .002
for i=1,hangers do
local u = ScenEdit_AddUnit({side=side, type='Facility', name='Hanger '..i, dbid=9, autodetectable=detectable, Lat=lat, Lon=lon})
u.group =basename
lat=lat -.002
end
end --function end

W_CreateAirBase('Red FOB','Red', {latitude='-3.16785920176629', longitude='128.539230124161'},2,2,4,8,2,1,true)

Thanks very much for the help guys, I'll play around with it today.

That works like a charm - thank you very much once again[&o]

Whicker
I'm going to use your bit in my next scenario on Iceland - have been mulling over some ideas for that one quite some time and your code will come in very handy.

OK now I just need to write up some briefings and now that the prosecution zone bit is fixed I can get to testing! Cheers guys
