Description

Description:
Sorts an array according to given algorithm. See sort for simple sorts.
Execution:
call
Groups:
Arrays

Syntax

Syntax:
[array, parameters, algorithm, direction, filter] call BIS_fnc_sortBy
Parameters:
array: Array - any unsorted array. Can contain any types
parameters: Array
  • used in the eval algorithm
  • input params are referenced in the sorting algorithm by _input0..9
  • a maximum of 10 input params is supported (0-9)
algorithm: Code - (Optional, default { _x })
direction: String - (Optional, default "ASCEND") case-insensitive
  • "ASCEND" for ascending sorting
  • "DESCEND" (or anything else) for descending sorting
filter: Code - (Optional, default { true }) code that needs to evaluate true for the array item to be sorted, otherwise item is removed
Return Value:
Array - sorted array

Examples

Example 1:
// sort numbers from lowest to highest _sortedNumbers = [[1,-80,0,480,15,-40], [], {_x}, "ASCEND"] call BIS_fnc_sortBy;
Example 2:
// sort helicopters by distance from player _closestHelicopters = [[_heli1,_heli2,_heli3], [], { player distance _x }, "ASCEND"] call BIS_fnc_sortBy;
Example 3:
// sort enemy by distance from friendly unit (referenced by local variable), the furthest first _furtherstEnemy = [[_enemy1,_enemy2,_enemy3], [_friendly], { _input0 distance _x }, "DESCEND", { canMove _x }] call BIS_fnc_sortBy;
