Question on arrays

[THobson]

I have an array of units.  I would like to create an other array from that which contains units of only a particular type (eg LandVehicles; Tank; Air etc.) contained in the fist array.  

countType tells me how many there are, but how do I identify them?

[dmakatra]

typeOf vehicle

Operand types:
vehicle: Object
Type of returned value:
String
Description:
Returns the class type of a given object

Example:
_class = typeOf _mi24

Somtin like this?

_vehicles = [car1,tank1,car2,tank2]

_tanks = []
_cars = []

_i = 0

#check
_veh = _vehicles select _i
? "car" counttype [_veh] > 0 : _cars = _cars + [_veh]
? "tank" counttype [_veh] > 0 : _tanks = _tanks + [_veh]
_i = _i + 1
?_i < count _vehicles : goto "check"

hint format ["Cars are %1\nTanks are %2", _cars,_tanks]

Blanco:
Thanks.  Yes something exactly like that.

Where did you get that?  It is not in my comref.

would something like
{if (typeOf _x == "tank") then {_tanks = _tanks + [_x]}} forEach _vehicles

work?  I will have a look at it anyway.  I am just getting the hang of the forEach but am still not sure when it work and when it won't

[THobson]

Code: [Select]

_tanks = []
{if ("tank" counttype [_x] > 0) then {_tanks = _tanks + [_x]}} forEach _vehListALLWorks!

Thanks I would not have got there without both of you.

[THobson]

Well it does something - but not yet quite what I want.  It ignors empty vehicles.

It's because your ComRef sux. Use the online one, or at least get an updated version for 1.96. And it's dmakatra n00by. Just call me Armsty.

[THobson]

Lol.  Okay, okay. Amsty.  I suppose if I do call you Amsty then it really is dmakatra

I got my comref from the Editors dept - and I also use the online ref that is there as well.  Is there a later version somewhere else?

[dmakatra]

Dude, you blind?

I suppose I must be.  I have the 'official' one that I got from Editors dept, and I have a link to the Unofficial one that is there.  Honestly - I never saw this one before.  Ooops

And thanks

[THobson]

I have just been looking at it.  It is very good.  

I see how I missed it.  I was searching on comand reference etc.

All I needed to do was click on Online References/Commands.  I missed it by looking too hard!!

It ignors empty vehicles.

I had the same problem with a satellite script and I solved it like this

_object = _this select 0

?((side _object == CIVILIAN) && ("tank" counttype [_object] > 0 && (count crew _object == 0)) : hint "tank is empty"

Empty vehicles are on the civilian side.

Excellent.  Thanks.  Like most things in OFP it is a case of 'why didn't I think of that?'
