How to filter out certain objects without class from all objects around?

[Rydygier 1317]

If I use for example:

	_nObj = nearestObject _pos;

This will return nearest object regardless of its class or lack of class (building, rabbit, tank, tree, unit, dragonfly, road segment...). Great. But how to achieve returning of a tree or bush object, but not road (or even certain kind of road segment, so nearRoads is only partial solution for roads segments) or fly? How to "sift out" only chosen part/kinds of class-less objects if possible at all?

The wiki page explains this.

In the type field, you can put almost anything from the hierarchy. From as wide as "MAN" to as narrow as "HMMWV".

While we're on the subject, if you want to save a couple of CPU cycles, use nearObjects. It's as above except that it doesn't sort the result array by distance.

Thanks, I of course have read biki's info about this command (must be nearest, cause I need nearest one only). So I know, that I can filter out only some class (or multiple classes for similar commands), also with higer hierarchy. Also I know, that without filtering by class, all objects will be considered, even class-less (and this is needed, I'm also after class-less objects here). My question is - with what code I can filter out only some of class-less objects, and keep other class-less considered. Eg. I want to know about closest to _pos fences, walls, trees or bushes but not about ponds, insects, other (so must sift out rest of class-less objects somehow...),

I feared that's what you were asking. :)

AS far as I know, the type field can't be used to exclude, only include.

nearestObjects allow more than one class to be specified. Have you tested to see if nearObject does too?

I fear that the only way you can do what you want is to grab a big array of nearestObjects filtered as best you can using type and then work on the array in a second script.

If they were important only objects with defined classes, then I would get along with filtering somehow. But what to do, when there is no defined class for some object (as ponds, plants, stuff...), that I could put into filter array one of near/nearest commands?

I'm thinking about retrieving object's .p3d file (nearestObject without any filter could return for example something like that: "244581: b_betulahumilis.p3d" and then typeOf _nObj returns empty string, means - no class for that object, that may be used as filter), then to do some string comparison to determine, what is it, but: isn't there a better way, that to construct huge array of strings for each possible .p3d?

Maybe some example: currently I gonna to try this:

	_nObj = nearestObjects [_pos, [], 50];
_nObj2 = _nObj;
_nR = _pos nearRoads 50;
{if (_x in _nR) then {_nObj = _nObj - [_x]}} foreach _nObj2;
_nObj = _nObj select 0;

If it will work, then I'm able to sift out at least road segments. But to do same with other class-less objects, I would need eg nearPonds command for ponds etc...

Hi,

I am allso having difficulty using this sort of command, so I will be watching this thread closely.

Please keep us informed of any progress. Thanks
