The function does not work according to the comment header: “This function adds an element to the beginning of an array and returns the array.” Furthermore this is stated in the comment header:
"Example:
array = [2,3,4]
[array, 1] call BIS_fnc_ArrayUnshift
array is now [1,2,3,4]"
This is not true. The actual result is: [1,3,2]
array = [2,3,4]
[array, 1] call BIS_fnc_ArrayUnshift
//This is how to add an element to the beginning of an array:
private ["_array", "_i"];
// Parameters: [array, element]
_array = _this select 0;
// Loop through the array, from right to left, and move everything one step to the right
for "_i" from (count _array) - 1 to 0 step -1 do
{
_array set [_i + 1, _array select _i];
};
//set first element
_array set [0, _this select 1];
_array
With new commands you can simply
reverse arr;
arr pushBack el;
reverse arr;
Done
However when japa comes from holiday, maybe he can add pushFront? It is a cpp method so why reinvent a wheel?
