Pyskool requires Python (version 2.5+, but not version 3.x) and Pygame (version 1.7+).
You almost certainly have Python already installed, and there are probably Pygame packages available via the package management system. Debian-based distros have python-pygame, openSUSE has python-pygame, Fedora has pygame, and FreeBSD has py25-game (for example).
To start Pyskool in Skool Daze mode, open a terminal window, change to the Pyskool directory, and do:
$ ./skool_daze.py
or, to run Pyskool in Back to Skool mode:
$ ./back_to_skool.py
When Python and Pygame are installed, open a terminal window, change to the Pyskool directory, and do:
$ ./skool_daze.py
to run Pyskool in Skool Daze mode; or, to run Pyskool in Back to Skool mode:
$ ./back_to_skool.py
When Python and Pygame are installed, double-click the skool_daze.py file in the Pyskool directory. To run Pyskool in Back to Skool mode, double-click back_to_skool.py.
If that doesn’t work, try the command line. Open a command prompt, change to the Pyskool directory, and do:
> skool_daze.py
to run Pyskool in Skool Daze mode; or, to run Pyskool in Back to Skool mode:
> back_to_skool.py
The skool_daze.py and back_to_skool.py executables support a few command line options:
