Description:: Attempts to sort given array either in ascending (true) or descending (false) order.
⚠
This will modify the original array!
Groups:: Arrays

Syntax:

array sort order

Parameters:

array: Array - Array to be sorted, can also be a nested array.

All array elements should be one of the following types:

String - Array of strings ["a","b","c"...]
Number - Array of numbers [1,2,3...]
Array - Array of subarrays [["a",1,2],["b",3,4],["c",5,6]...]. Subarrays should be of the same structure. Subarray elements other than String or Number will be ignored during sorting.

Mixed arrays ["a",1,[true], ...] are not supported and results are undefined.

order: Boolean - Sorting order.

Return Value:

Nothing

Example 1:: _arr = [5.21725,1.30859,4,5.03028,1]; _arr sort true; hint str _arr; //[1,1.30859,4,5.03028,5.21725]
Example 2:: _dev = ["ja","pa","pa","tram","tara"]; _dev sort false; hint str _dev; //["tram","tara","pa","pa","ja"]
Example 3:: #define ASC true #define DESC false _scores = [[123,"bob",15],[123,"bill",20],[200,"dave",21],[200,"steve",11]]; _scores sort DESC; hint str _scores; //[[200,"steve",11],[200,"dave",21],[123,"bob",15],[123,"bill",20]]
Example 4:: Sort buildings by distance and return position of the most distant building: _buildings = player nearObjects ["Land_Cargo_Patrol_V1_F", 500]; _buildings = _buildings apply { [_x distance player, _x] }; _buildings sort false; hint format [ "Most distant building is at %1, distance %2 m", getPos (_buildings select 0 select 1), round (_buildings select 0 select 0) ];
