An example using FileManager but it has to read once to retrieve how many files exist and a second to select the random one:

pawn Код:

new dir: dHandle, item[40], type, counter, random_file;
    
dHandle = dir_open("path_here");

while (dir_list(dHandle, item, type))
{
    if(type == FM_FILE) counter++;
}
        
dir_close(dHandle);

random_file = random(counter);
counter = 0;
dHandle = dir_open("path_here");

while (dir_list(dHandle, item, type))
{
    if(type == FM_FILE && counter++ == random_file) break;
}

dir_close(dHandle);
printf("random file: \"%s\"", item);

If you know the number of files will not exceed a certain amount, an array to store the file names and avoid the second loop is also a choice.

and how can i do it that he only select .map files?

If there are files with different extensions in that directory, you will need to check the last 4 characters (matching .map).

pawn Код:

new dir: dHandle, item[40], type, counter, random_file;

dHandle = dir_open("./scriptfiles");

while (dir_list(dHandle, item, type))
{
    if(type == FM_FILE && strfind(item, ".map", true, strlen(item) - 4) != -1) counter++;
}

dir_close(dHandle);

random_file = random(counter);
counter = 0;
dHandle = dir_open("./scriptfiles");

while (dir_list(dHandle, item, type))
{
    if(type == FM_FILE && strfind(item, ".map", true, strlen(item) - 4) != -1 && counter++ == random_file) break;
}

dir_close(dHandle);
printf("random file: \"%s\"", item);

If you can, store all .map files in a folder called "Maps" or something else and you do not need strfind. The code from previous post will work.

Current random algorithm gives few results over and over again. If you want any map to have a chance, you may use MerRandom plugin.
