Description
- Description:
- Selects random position according to given params within given area
- Execution:
- call
- Groups:
- Map and Markers
Syntax
- Syntax:
- [whitelist, blacklist, code] call BIS_fnc_randomPos
- Parameters:
- [whitelist, blacklist, code]: Array
- whitelist (Optional): Array - whitelisted areas. If not given, whole map is used. Areas could be:
- blacklist (Optional): Array - blacklisted areas. If not given, water is blacklisted. Areas could be:
- code (Optional): Code - 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:
_randomPosMapNoWater = [] call BIS_fnc_randomPos;- Example 2:
_randomPosMapNoWater = [nil, ["water"]] call BIS_fnc_randomPos;- Example 3:
_randomPosMapNoLand = [nil, ["ground"]] call BIS_fnc_randomPos;- Example 4:
_randomPosMap = [nil, []] call BIS_fnc_randomPos;- Example 5:
_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.
randomRoadPosAroundPlayer = [[[position player,50]],[], {isOnRoad _this}] call BIS_fnc_randomPos;
