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