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.
- Groups:
- Object Detection
Syntax 1
- Syntax:
- nearestObject [position, type]
- Parameters:
- position: Object or Array format Position2D or Position3D - 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: Array format Position2D or Position3D - position to start search at
- Return Value:
- Object - nearest object, objNull otherwise
Syntax 3
- Syntax:
- position nearestObject typeOrId
- Parameters:
- position: Position3D or Position2D - position to start search at
- typeOrId: String - type of object (see typeOf, class type) or 2.10 Visitor id (see getObjectID)
- Return Value:
- Object - nearest object, objNull otherwise
Syntax 4
- Syntax:
- position nearestObject id
- Parameters:
- position: Array format Position2D or Position3D - position to start search at
- id: Number - object Visitor id
- Return Value:
- Object - nearest object, objNull otherwise
Examples
- Example 1:
- Example 2:
- Return the object with ID 123456:
- Example 3:
- Example 4:
- Return the nearest object with (typeOf _nObject == "#XXXX") -> #mark, #slop, etc. Unlimited search range:
Return the nearest object with (typeOf _nObject != ""). Search range is 50m:
- Example 5:
- (See also allMissionObjects):

The ID for Syntax 4 may be dynamically obtained via the following (as of Arma 3 v1.88):
(for Arma 3 v2.10 or newer, use getObjectID instead)
// 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 };

- 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:
