File System
|
|
|
|
No stdio calls should be used by any part of the game, because of all sorts
|
|
of directory and separator char issues. Throughout the game a forward slash
|
|
should be used as a separator. The file system takes care of the conversion
|
|
to an OS specific separator. The file system treats all file and directory
|
|
names as case insensitive.
|
|
|
|
The following cvars store paths used by the file system:
|
|
|
|
"fs_basepath" path to local install
|
|
"fs_savepath" path to config, save game, etc. files, read & write
|
|
|
|
The base path for file saving can be set to "fs_savepath" or "fs_basepath".
|
|
|
|
