From: Holger Schemel Date: Sat, 17 Oct 2020 23:54:32 +0000 (+0200) Subject: added support for multiple user game data directories X-Git-Tag: 4.2.1.0~48 X-Git-Url: https://git.artsoft.org/?a=commitdiff_plain;h=3b7f6c6d572ffd50744e76f9ed93733785e13211;p=rocksndiamonds.git added support for multiple user game data directories This change adds support for game data directories for multiple users, to store individual user configuration files (like setup data and last played level sets and levels) and individual user content files (like personal tape files, but not personal level sets and scores, which are still stored to be accessible by all users). Special treatment is done for the game data files of the first user, which are still stored in the main game data directory like before, so there are no changes in file and directory paths for the "default user", regardless if multiple user support is enabled or disabled. --- diff --git a/src/libgame/misc.c b/src/libgame/misc.c index bf2d2c42..217895c0 100644 --- a/src/libgame/misc.c +++ b/src/libgame/misc.c @@ -3761,14 +3761,14 @@ void FreeCustomArtworkLists(struct ArtworkListInfo *artwork_info) char *getLogFilename(char *basename) { - return getPath2(getUserGameDataDir(), basename);
