I am calling them secret since they are not in the DOCs part and I have not seen them in any GSCs before.

Trying to squeeze COD2 and find tricks to spawn clips and trigger_damage from script I "discovered" the following functions that are not documented but can be helpful. The deal with file handling, reading and writing from script.

Here a quick example and you will guess the powers, writting logs, loggin stats, when freadln works ability to have a scriptdata text file contain players with special abilities/restrictions, e.g. you could have a list of players that can be medics and give them improved ability to heal people:

Code:

filehandle = openfile("myfile.txt", "append");
fprintln(filehandle, "Hello my log\n");
fclose(filehandle);


Here some of the functions that I understand so far:

filehandle = openfile(filename, filemode)
Opens a file name filename in the directory scriptdata under the directory your fs_game shortcut points to. If you do not have a fs_game on your COD2 call it most likely starts in main/scriptdata. If have my fs_game set to rfsmod so the files need to be in rfsmod\scriptdata.

Returns a filehandle that represents the file from now on and this value has to be used on calls to fprintln, fgetarg, freadln and fopen as the first parameter. This filehandle is an integer and -1 means that the file could not be opened. Typically wrong file location.

filename = name of the file to open
filemode = "append" or "read" or "write" - Self explanatory

fprintln(filehandle, stringtowrite)
Writes a string to the file pointed to by the filehandle previously obtained from fileopen.

filehandle = handle returned from openfile that specifies the file to write to.

stringtowrite = string to be written to the file. This will be terminated by a comma and not as expected a linefeed. This is most likely for multi system compatability to avoid the issue with if 0c or 0a comes first. You can force a line feed with \n and use most likely similiar escape characters know from C.

Have not tested this but most likely returns the number of bytes written or -1 if not possible.

closefile(filehandle)
Close the file and flushes the contents

filehandle = handle returned from openfile that specifies the file to write to.

freadln(filehandle)
Still trying to get to work.

fgetarg(filehandle)
Have not hacked its syntax.
