Where does save_dir get its value ? #246432 01/15/09 07:51 01/15/09 07:51

When the file does not exist, it tries to create it (as is stated in the manual) in the save_dir directory. The problem I see is that save_dir is NULL, which causes a whole set of issues (i.e. the file handle returned from file_open_write is '0' and any subsequent attempts to write to the file cause a crash [invalid pointer] ...). I know how to work around this issue, but one thing that interests me is where / how the save_dir is intialized (I know that I could set it in a .WDL ... I want to know how the engine does it).

By default, it's the work folder; it can be set to another folder with the -dir command line option or the SAVEDIR statement in a WDL file. Yup ... I read that, but the point is that the save_dir is not set to point to the work directory ... it's an empty (NULL?) string when I show it (via printf()) ... I know that the "-dir" option is supposed to set it (as well as the SAVEDIR in a WDL file), but I am just frustrated / surprised that it does not (apparently) point to the work directory as it should (according to the manual) ...

If you write a file with fopen, e.g. fopen("test.txt","wb"); without an specific absolute path, the file is automatically created in the work folder of your game. Therefore it's correct that if save_dir is "" it means the same as if it was filled with the "real" work dir. BTW: You do not need a wdl file, or the -dir command. It's just enough to copy a string into save_dir (e.g. str_cpy(save_dir,work_dir); )
