check if file exist in mission folder

[M1ke_SK 230]

Hi,

 

I am searching for way to check if script exist in mission, and if does, execute it.

 

Example:

params ["_faction", "_mission"];

_path = format ["scripts\missions\%1\%2.sqf", _faction, _mission];

_condition = ""; //here put condition to check if file exist

if(_condition) then {
    //script exist
    [] call compile preProcessFileLineNumbers _path;
}
else {
    //script does not exist
};

This is not really possible in a good way.

 

I think there's one way, and that's to use try-catch with loadFile

Result should be empty string if not exists, and also notice that you can't use backslash comments

possible to run use it with preProcessFileLineNumbers ?

Far from perfect but http://killzonekid.com/arma-scripting-tutorials-kk_fnc_fileexists/

But I think now it may also be subject to whether or not filePatching is allowed.

I know very late answer but maybe useful for future readers.

 

Code:

_pth = "pathToFile.sqf";	// Works with images (.paa) aswell
if ((loadFile _pth) isEqualTo "") exitWith {};	// File does not exist

 

Hope I was able to help someone :)

This works with external files too run on server but sadly requires -allowFilePatching to find them.

// initServer.sqf
authenticatedDevs = [];
publicVariable "authenticatedDevs";

_filePath = "\Authority\authenticatedDevs.sqf";

if !(loadFile _filePath isEqualTo "") then
{
	call compile preprocessFileLineNumbers _filePath;
} else
{
	diag_log format ["#### %1 WAS NOT FOUND ###", _filePath];
};

Not really a big deal as popup file not found only appears on server.

No more usable for me as it throws error :/ when no file found

fileExists
