We also have them in a file for easy install: pip install -r requirements.txt

We use nuitka, pyinstaller, and AppImage to make the executables.

For Windows we use nuitka to create our .exe files. While slower to compile than pyinstaller which was used in older builds, it provides a smaller executable size and doesn't tick off Windows Defender. pyinstaller should only be used as a backup if nuitka doesn't work for you for some reason. Both are able to be installed using pip install.

Below is the full terminal command we use to compile the launcher, and below that is a stripped down version without version information and such:

python -m nuitka --onefile --windows-console-mode=disable --noinclude-data-files="pygame/freesansbold.ttf" --include-data-dir="src/GUI"="GUI" --include-data-dir="src/Languages"="Languages"  --windows-icon-from-ico="src/GUI/images/p2mm-icon.ico" --product-name="Portal 2: Multiplayer Mod Launcher" --file-description="The launcher for P2:MM." --product-version="INSERT VERSION HERE" --file-version="INSERT VERSION HERE" --copyright='© 2024 Portal 2: Multiplayer Mod Team' "src/MainWindow.py"

python -m nuitka --onefile --windows-console-mode=disable --noinclude-data-files="pygame/freesansbold.ttf" --include-data-dir="src/GUI"="GUI" --include-data-dir="src/Languages"="Languages"  --windows-icon-from-ico="src/GUI/images/p2mm-icon.ico" "src/MainWindow.py"

Below is the terminal command to compile using pyinstaller:

pyinstaller "src/MainWindow.py" -F -i "src/GUI/images/p2mm-icon.ico" --noconsole --add-data "src/GUI;GUI" --add-data "src/Languages;Languages"

For Linux we switched to using AppImage and we made a tool to help with that, simply have docker installed and run ./tools/build-docker.sh while in the root directory.

WARNING! For some reason on some Linux distributions, FUSE is not installed by default which is needed for both compiling and running AppImages. Information for installing FUSE on your distribution can be found here: AppImageKit's Wiki

If you don't want to use AppImage/docker, you can still use pyinstaller:

pyinstaller "src/MainWindow.py" -F --add-data "src/GUI:GUI" --add-data "src/Languages:Languages"

• If you want to fork the project and do your own releases you need to change the variables at the top of src/Scripts/Updater.py to your own information and update the values in AppImageBuilder.yml as well as information in respective compiling commands like with nuitka.

Portal 2: Multiplayer Mod version 2.3.0 will be our definitive version, so we won't make any significant updates after it is fully released. Before this happens, we will work on minor updates leading to the full version. We will accept any substantial changes or features for P2:MM during this period. However, we will not be doing much work at all after release or make any new releases in general. The only reasons we would make a new release would be when someone contributes a new translation, an improvement of a current translation, some other minor bug fix we didn't catch, or a map support file for a workshop map. Even after this final release, you can still fork it to build off our work! Please make sure you give credit to this repository!
