Title: Fred2Open
Post by: Amon_Re on April 16, 2003, 10:37:03 am

More questions.... sorry guys :)

Currently my freespace folder is ordered like this:
c:\games\freespace
c:\games\freespace\data
c:\games\freespace\fsport
c:\games\freespace\fsport\data
c:\games\freespace\othercampaign
c:\games\freespace\othercampaign\data
...

Now, with the - mod parametre it's easy to tell FS2_Open to use those directories aswell, wich enables me to keep my main datafolder clean.

Now, however, that i'm toying with Fred2Open i was wondering if such a thing can also be done with Fred2Open.

I already tried -mod but that didn't work out... :)

Cheers,

Good catch, if it doesn't, it should, DTP?

I did this yesterday; eventually, this is quite simple. We must allow FRED2 to parse its command-line *before* it initializes the C file system. Then, the parser will be able to detect the "-mod" switch if FRED2 is launched this way: "fred2.exe -mod ", what will trigger the CFile init sequence to build a secondary file system on the "mod_name" directory. Here are the details for the dev team:

* File "FRED2\Management.cpp", function "fred_init()"; just before this statement:

        if (cfile_init(Fred_exe_dir))        exit(1);

You could simply add this one:

        parse_cmdline(GetCommandLine());

Adding this #include line at the beginning of this file will be required too:

        #include "cmdline.h"   // parse_cmdline

* Practically, I prefered to pass a variable (szCommandLine) to the parse_ ... function; I initialized it there:

File "FRED2\Fred.cpp", function "CFREDApp::InitInstance()":

        /////////////////////////////////////////////////////////////////////////////
        // CFREDApp initialization
        char *szCommandLine;
        BOOL CFREDApp::InitInstance()
        {
                ...
                szCommandLine = GetCommandLine();   // retrieve the command-line string for the FRED2 process

                // not added by me
                strcpy(Fred_exe_dir, __argv[0]);
                ...
        }

Of course, I "externalized" this variable in "Fred.h":

        extern char *szCommandLine;


That's all! This works seamlessly for me. My new background bitmaps which are located in a mod directory are loaded correctly in the background editor :) I hope I have been cleared in my explanations (did not succeed to indent the code here). Also, sorry for non-coders people: the above lines must be scary for you.

They don't scare me, but i don't have the source nor a compiler ;)

An exe would be nice... :)
