Run opensurge --help
Extract the MOD to your filesystem and run the game.
- Windows: launch the executable.
- Linux: run
opensurge --game-folder /path/to/mod/folder/on the command-line. - macOS: use the
--game-foldercommand-line option or launch the native executable if provided.
Use preferably the same engine version as the MOD if a native executable isn't provided (check logfile.txt).
Linux users should extract the MOD into their home folder, preferably into ~/Downloads.
Visit the wiki for more information on user-made MODs.
Content is distributed in the following locations: (since version 0.6.1)
bin: executable fileshare: game assets (images, audio, levels, scripts, etc.)user: user-modifiable data (preferences, logs, screenshots, additional assets such as user-made levels)
The default paths of these locations vary according to the platform:
-
Windows (.zip package):
bin:./opensurge.exeshare:.user:.or%OPENSURGE_USER_PATH%
-
Linux:
bin:/usr/games/opensurgeshare:/usr/share/games/opensurge/user:~/.local/share/opensurge/or$XDG_DATA_HOME/opensurge/or$OPENSURGE_USER_PATH
-
Linux (Flatpak):
bin:flatpak run org.opensurge2d.OpenSurgeshare:/var/lib/flatpak/app/org.opensurge2d.OpenSurge/current/active/files/share/opensurge/user:~/.var/app/org.opensurge2d.OpenSurge/data/opensurge/or$OPENSURGE_USER_PATH
If you use
$OPENSURGE_USER_PATH, make sure it points to a subdirectory of~/Downloads($XDG_DOWNLOAD_DIR). -
Linux (Snap):
bin:snap run opensurgeshare:/snap/opensurge/current/share/games/opensurge/user:~/snap/opensurge/current/.local/share/opensurge/or$OPENSURGE_USER_PATH
If you use
$OPENSURGE_USER_PATH, make sure it points to a subdirectory of your home folder. -
macOS:
bin:Contents/MacOSshare:Contents/Resourcesuser:~/Library/Application Support/opensurge/or$OPENSURGE_USER_PATH
If you intend to hack the game, it's easier to have all files in the same place (read-write), because some of the above folders are read-only. Download the sources, extract them to your filesystem and use the --game-folder command-line option as explained in Running MODs.
Tip: since version 0.6.1 you can use the command-line option --verbose to see where the files are. The directories will appear at the beginning of the output.
Dependencies:
- Allegro version 5.2.7 or later
- SurgeScript version 0.6.0 or later
- PhysicsFS version 3.2.0 or later
Compile as usual:
cd /path/to/opensurge/
mkdir build && cd build
cmake ..
make -j4
sudo make install
Use cmake-gui or ccmake for tweaking, like installing the engine to or finding the dependencies on non-standard paths.
