From time to time I come back to game development mainly to create simple experimental games and sometimes to partecipate to some contest such as PyWeek.

This little framework is the latest attempt to create a basic framework to help me in the process of building simple 2D games; I don't expect it to grow in to something professional or generally useful.

The framework is being developed with CPython 3.4 (now 3.6), if you want to support other versions of python you have to do some work by yourself, and please provide patches :)

The framework exposes a couple of utility classes in order to get started quickly with the game logic; the fundamental pieces are the Director class and the Scene class:

• Director: handles scense and propagates events to the active Scene object
• Scene: abstracts a scene; receives user input events, and provide two fundamental callbacks on_draw and on_update; for other callbacks please have a look at yaff/scene.py (sorry, no documentation yet)

I think this is the very basic functionality that is needed in order to focus to game logic.

In order to run the simplest example:

• create your virtual environment and install requirements with: pip install -r requirements.txt
• install yaff in the virtualenv with: python setup.py install
• run: python -m example_bouncing_balls.main
• alternative use the yaff runner: yaff run example_bouncing_balls

The other projects included in the repo are usually broken and may require more work to run, for example pyweek20 requires more effort to run it.
