PyVGDL

PyVGDL is a high-level video game description language (VGDL) built on top of pygame.

The aim is to decompose game descriptions into two parts: 1) a very high-level description, close to human language, to specify the dynamics, which builds on 2) an ontology of preprogrammed concepts for dynamics, interactions, control. Programmers extend the possibilities of (1) by writing modules in (2), and game designers can very quickly compose new games from those components without programming.

References

The original idea was discussed in the 2012 Dagstuhl seminar, with a full description presented at the IEEE CIG conference 2013 (this is also the reference paper to cite if you use PyVGDL for academic work).

Installation and Dependencies

  • Get the pygame package

  • (Alternative Method) Using Homebrew and virtualenv on Mac OSX

          brew install sdl sdl_image sdl_mixer sdl_ttf portmidi
      pip install mercurial
      pip install hg+http://bitbucket.org/pygame/pygame

  • For all reinforcement learning usage, also get the PyBrain machine learning library

  • For the upload to youtube functionality, you will need the gdata library

  • Download repository

       git clone git://github.com/schaul/py-vgdl.git

  • Try examples

       python -m examples.gridphysics.aliens
