Description

Description:
Selects random position according to given params within given area
Execution:
call
Groups:
Positions

Syntax

Syntax:
[whitelist, blacklist, code] call BIS_fnc_randomPos
Parameters:
whitelist: Array - whitelisted areas. If not given, whole map is used. Areas can be:
blacklist: Array - (Optional, default []) blacklisted areas. If not given, water is blacklisted. Areas can be:
  • Object - trigger
  • String - marker name or special tags names: "water" - exclude water, "ground" - exclude land
  • Array - in format [center, radius] or [center, [a, b, angle, rect]]
  • Location - location
code: Code - (Optional, default { true }) custom condition which should return true for current position candidate passed in _this variable to be accepted. If not specified all candidates are accepted
Return Value:
Array - position candidate in format [x,y,z] or [0,0] if position cannot be found

Examples

Example 1:
private _randomPosMapNoWater = [] call BIS_fnc_randomPos;
Example 2:
private _randomPosMapNoWater = [nil, ["water"]] call BIS_fnc_randomPos;
Example 3:
private _randomPosMapNoLand = [nil, ["ground"]] call BIS_fnc_randomPos;
Example 4:
private _randomPosMap = [nil, []] call BIS_fnc_randomPos;
Example 5:
private _randomPosAroundPlayer = [[[position player, 50]], []] call BIS_fnc_randomPos;

The code parameter here can be quite powerful. If using Example 5 above, adding code as below will make the returned positions always be on a road.
private _randomRoadPosAroundPlayer = [[[position player, 50]], [], { isOnRoad _this }] call BIS_fnc_randomPos;
