Description

Description:
Returns a list of nearest terrain objects of the given types to the given position or object, within the specified distance. If more than one object is found they will be ordered according to 3D distance to the object (i.e. the closest one will be first in the array). In contrast to nearestObjects this command returns terrain placed objects like trees, rocks and buildings which don't necessarily need an associated config class.

Possible type names:"TREE", "SMALL TREE", "BUSH", "BUILDING", "HOUSE", "FOREST BORDER", "FOREST TRIANGLE", "FOREST SQUARE", "CHURCH", "CHAPEL", "CROSS", "BUNKER", "FORTRESS", "FOUNTAIN", "VIEW-TOWER", "LIGHTHOUSE", "QUAY", "FUELSTATION", "HOSPITAL", "FENCE", "WALL", "HIDE", "BUSSTOP", "ROAD", "FOREST", "TRANSMITTER", "STACK", "RUIN", "TOURISM", "WATERTOWER", "TRACK", "MAIN ROAD", "ROCK", "ROCKS", "POWER LINES", "RAILWAY", "POWERSOLAR", "POWERWAVE", "POWERWIND", "SHIPWRECK", "TRAIL"

Since Arma 3 v1.62 it is possible to switch the sorting algorithm off by providing optional param, which significantly increases the performance of this command, especially if the search is performed with large radius.
Since Arma 3 v1.66 it is possible to switch search and sorting mode between 2D and 3D.
Since Arma 3 v2.00 this command also returns missing roads: "ROAD", "MAIN ROAD", "TRACK", "TRAIL"

ⓘ
Types which are missing are not present in the given world. Virtual Reality has no terrain objects. Last updated Arma 3 logo black.png1.99

Syntax

Syntax:
nearestTerrainObjects [position, types, radius, sort, 2Dmode]
Parameters:
position: Object, PositionAGL or Position2D - where to find objects, center position
types: Array - list of case-insensitive types of the objects to search for. [] to search without filters
radius: Number - range from center position to search for objects
sort: Boolean - (Optional, default true) sort objects by distance to the center or not Template:Since
2Dmode: Boolean - (Optional, default false) the object search and sorting mode: true - 2D, false - 3D Template:Since
Return Value:
Array - array of terrain objects

Examples

Example 1:
nearestTerrainObjects [player, ["Tree", "Bush"], 200];
Example 2:
nearestTerrainObjects [player, ["House"], 200];
Example 3:
nearestTerrainObjects [[2716, 2949, 0], ["Chapel", "Fuelstation"], 100];
Example 4:
Return every terrain object in 50 metres radius around player sorted, closest first:nearestTerrainObjects [player, [], 50];
Example 5:
Return every terrain object in 50 metres radius around player unsorted:nearestTerrainObjects [player, [], 50, false];
Example 6:
Hide all terrain objects nearestTerrainObjects could find: if (isServer) then { private _allTerrainObjects = nearestTerrainObjects [ [worldSize / 2, worldSize / 2], [], worldSize * sqrt 2 / 2, false ]; { _x hideObjectGlobal true } forEach _allTerrainObjects; };

Since Arma 3 v1.66 the default sorting is done according to 3D distance not distance2D as before. This is an attempt to correct some very old bug in implementation.

Be aware that some terrain objects types might be tricky to be found, such as terrain rocks and boulders which are not considered to be "ROCKS" or "ROCK", but "HIDE". Example: nearestTerrainObjects [player, ["HIDE"], 20]; // [939688: bluntstone_01.p3d,939691: garbagebags_f.p3d,939671: wreck_car_f.p3d,939692: junkpile_f.p3d]

Large bridges are map type "ROAD". Small foot bridges are not roads and not included into road net.
