Description

Description:

Returns the nearest object of given type (or inherited classes) to given position within a sphere. Hardcoded radius is 50 meters. Unlike with nearestObjects, where distance is measured in 2D space, nearestObject will be closest object in 3D space.

ⓘ

in OFP, only objects of the exact provided class are found.
if an object ID is used (Alternative Syntax 3, see Example 2) the search range is unlimited

Groups:

Object Detection

Syntax 1

Syntax:: nearestObject [position, type]
Parameters:: [position, type]: Array
: position: Position3D or Position2D or Object - position to start search at
: type: String - type of object (see typeOf, class type)
Return Value:: Object - Nearest object, objNull otherwise

Syntax 2

Syntax:: nearestObject position
Parameters:: position: Position3D or Position2D - position to start search at
Return Value:: Object - Nearest object, objNull otherwise

Syntax 3

Syntax:: position nearestObject type
Parameters:: position: Position3D or Position2D - position to start search at
: type: String - type of object (see typeOf, class type)
Return Value:: Object - nearest object, objNull otherwise

Syntax 4

Syntax:: position nearestObject id
Parameters:: position: Position3D or Position2D - position to start search at
: id: Number - object Visitor id
Return Value:: Object - nearest object, objNull otherwise

Examples

Example 1:: _nObject = nearestObject [2345, 6789]; _nObject = nearestObject [player, "StreetLamp"];
Example 2:: Return the object with ID 123456: _nObject = [0,0,0] nearestObject 123456;
Example 3:: _nObject = getPos player nearestObject "StreetLamp";
Example 4:: Return the nearest object with (typeOf _nObject == "#XXXX") -> #mark, #slop, etc. Unlimited search range: _nObject = _position nearestObject -1; Return the nearest object with (typeOf _nObject != ""). Search range is 50m: _nObject = nearestObject _position;
Example 5:: (See also allMissionObjects): _blood = nearestObject [player, "#slop"]; _step = nearestObject [player, "#mark"]; _track = nearestObject [player, "#track"]; _crater = nearestObject [player, "#crater"];

Gnashes: The ID for Alternative Syntax 3 may be dynamically obtained via the following (as of Arma 3 v1.88): // returns Object Terrain/Visitor ID, or -1 if no ID found (invalid/null object) cursorObject call { private _obj = str (param [0, objNull]); private _id = -1; private _find = ((_obj find "#") + 2); if (_find > 1) then { private _len = ((_obj find ":") - _find); _id = _obj select [_find, _len]; parseNumber _id; }; _id };

blackfisch: Note, that if you want to check for the nearest Unit you have to check for CAManBase instead of Man, since Man will also return any wildlife population in that Area: nearestObject [player, "Man"]; // could possibly return rabbits or other wildlife nearestObject [player, "CAManBase"]; // only returns units
