Pygame_sdl2

Pygame_sdl2 is a reimplementation of the Pygame API using SDL2 and related libraries. The initial goal of this project are to allow games written using the pygame API to run on SDL2 on desktop and mobile platforms. We will then evolve the API to expose SDL2-provided functionality in a pythonic manner.

Downloads

Nightly builds are available from:

http://nightly.renpy.org/pygame_sdl2/

An official release will be coming to pypi shortly.

License

New code written for pygame_sdl2 is licensed under the Zlib license. Some code - including compiled code - is taken wholesale from Pygame, and is licensed under the LGPL2. Please check each module to determine its licensing status.

See the COPYING.ZLIB and COPYING.LGPL21 files for details - you'll need to comply with both to distribute software containing pygame_sdl2.

Current Status

Pygame_sdl2 builds and runs on Windows, Mac OS X, and Linux, with a useful subset of the pygame API working. While not as well documented, it has also run on Android, iOS, and inside the Chrome browser. The following modules have at least some implementation:

  • pygame_sdl2.color
  • pygame_sdl2.display
  • pygame_sdl2.draw
  • pygame_sdl2.event
  • pygame_sdl2.font
  • pygame_sdl2.gfxdraw
  • pygame_sdl2.image
  • pygame_sdl2.joystick
  • pygame_sdl2.key
  • pygame_sdl2.locals
  • pygame_sdl2.mixer (including mixer.music)
  • pygame_sdl2.mouse
  • pygame_sdl2.scrap
  • pygame_sdl2.sprite
  • pygame_sdl2.surface
  • pygame_sdl2.sysfont
  • pygame_sdl2.time
  • pygame_sdl2.transform
  • pygame_sdl2.version

Experimental new modules include:

  • pygame_sdl2.render
  • pygame_sdl2.controller

Current omissions include:

  • Modules not listed above.
  • APIs that expose pygame data as buffers or arrays.
  • Support for non-32-bit surface depths. Our thinking is that 8, 16, and (to some extent) 24-bit surfaces are legacy formats, and not worth duplicating code four or more times to support. This only applies to in-memory formats - when an image of lesser color depth is loaded, it is converted to a 32-bit image.
  • Support for palette functions, which only apply to 8-bit surfaces.

Building

Building pygame_sdl2 requires the ability to build python modules; the ability to link against the SDL2, SDL2_gfx, SDL2_image, SDL2_mixer, and SDL2_ttf libraries; and the ability to compile cython code.

To build pygame_sdl2, install the build dependencies:

Ubuntu:

sudo apt-get install build-essential python-dev libsdl2-dev \
    libsdl2-image-dev libsdl2-mixer-dev libsdl2-ttf-dev \
    libjpeg-dev libpng12-dev virtualenvwrapper

Mac OS X (with brew):

brew install sdl2 sdl2_gfx sdl2_image sdl2_mixer sdl2_ttf
sudo pip install virtualenvwrapper

Open a new shell to ensure virtualenvwrapper is running, then run:

mkvirtualenv pygame_sdl2
pip install cython

Change into a clone of this project, and run the following command to modify the virtualenv so pygame_sdl2 header files can be installed in it:

python fix_virtualenv.py

Finally, build and install pygame_sdl2 by running:

python setup.py install

Windows

To build on windows, change into the pygame_sdl2 checkout, clone renpy/pygame_sdl2_windeps using a command like:

git clone https://github.com/renpy/pygame_sdl2_windeps

and then build and install using:

python setup.py install

This assumes you have installed a version of Visual Studio that is appropriate for the version of Python you are using.

C Headers

A small number of C headers can be installed using the command:

python setup.py install_headers

These headers export functions statically, and must be initialized by including "pygame_sdl2/pygame_sdl2.h" and calling the (C-language) import_pygame_sdl2() function from each C file in which a function will be called. The following functions are exposed:

  • PySurface_AsSurface - Returns the SDL_Surface underlying a pygame_sdl2.Surface.
  • PySurface_New - Wraps an SDL_Surface in a new pygame_sdl2.Surface.

Contributing

We're looking for people to contribute to pygame_sdl2 development. For simple changes, just give us a pull request. Before making a change that is a lot of work, it might make sense to send us an email to ensure we're not already working on it.
