BIS fnc codePerformance – Talk

Latest revision as of 11:53, 11 January 2023

This is great function but needs an alternative syntax for convenience and ease of remembering:

{code} call BIS_fnc_codePerformance;

which would be set at default 10,000 iterations.

Please Karel, make it happen :)

(ArmA3 1.14) Please always take advantage of the second and third parameters when running code on BIS_fnc_codePerformance. And it is not suggested to use reserved variables under scheduled environment. E.g.

['
    [ { a = _this } ] spawn {
        private "_code";
        _code = [_this, 0, {}, [{}]] call BIS_fnc_param;
        { _x call _code; } forEach allUnits;
    };
'] call BIS_fnc_codePerformance;

There will be a great latency until GUI being displayed, never do like that, on the contrary, we should:

['
    {
        private "_code";
        _code = [_this, 0, {}, [{}]] call BIS_fnc_param;
        { _x call _code; } forEach allUnits;
    }'
, [ {a = _this } ], 1000] call BIS_fnc_codePerformance;

As for the third parameter, only run the code with desired loop and not always 1000 times like the default set:

[‘
 a = 0; b = true;
 for [{_i = 0},{_i < 10 && b},{_i = _i + 1}] do {
   a = a + 1; 
   if (a >= 7) then {b = false};
 };’
 ,[],1000] call BIS_fnc_codePerformance;
//Sometimes such 1000 loops will freeze the game directly.

So separating all three parameters and using them wisely are recommended.
