{ | |||
_array [[set]] [_i, [[nil]]]; | |||
}; | |||
[[hint]] [[str]] _array; //[[hint]] is [any,any,any,any]</code> | |||
<code>_array = []; | |||
[[for]] "_i" [[from]] 0 [[to]] 3 [[do]] | |||
{ | |||
_array = _array + [ [[nil]] ]; | |||
}; | |||
[[hint]] [[str]] _array; //[[hint]] is [any,any,any,any]</code> | |||
That could be a problem if you're trying to standardize array length by filling empty elements with nil values. Use [[set]] for it's speed over [[a plus b]]. | |||

(A3 1.26) It is recommended to use pushBack instead of BIS_fnc_arrayPush.
_array = [1,2,3]; _array pushBack 4; //same as [_array, 4] call BIS_fnc_arrayPush;

pushBack does not support nil while set and a plus b do. For example:
_array = []; for "_i" from 0 to 3 do { _array pushBack nil; }; hint str _array; //hint is []_array = []; for "_i" from 0 to 3 do { _array set [_i, nil]; }; hint str _array; //hint is [any,any,any,any]_array = []; for "_i" from 0 to 3 do { _array = _array + [ nil ]; }; hint str _array; //hint is [any,any,any,any]That could be a problem if you're trying to standardize array length by filling empty elements with nil values. Use set for it's speed over a plus b.
