## Dependencies

### most of functionality

> - six https://pypi.python.org/pypi/six/
> - pyglet http://code.google.com/p/pyglet/

### particles support

> - numpy www.numpy.org

### audio and video support by AVbin

> - AVbin http://avbin.github.io/AVbin/Home/Home.html

### audio support by SDL

> - in Windows, pygame http://www.pygame.org
> - in unix-like OSes libraries sdl 1.2 and sdl-mixer 1.2; in debian/ubuntu their packages are libsdl1.2 and libsdl-mixer1.2
> - in Mac, theres no confirmed info. Should be similar to unix.

What explicit dependencies are declared in the setup.py ? six, pyglet from hg repository

## Compatibility

Compatibility notes at the time of writing, March 2014

> - python : cocos needs python 2.6, 2.7 or 3.3+ The cocos codebase has direct support for 2.x and 3.x, so no need to run 2to3

> - pyglet : pyglet 1.2 or better

>   > - In pypi the last pyglet is 1.1.4, from 2009
>   > - In pyglet’s googlecode downloads the last is an old 1.2alpha1 (2012)
>   > - It is recomended to use pyglet from repo at a revision near the tip.
>   > - For reference, this cocos release was tested with revision c7f948a848cb of pyglet, dated 2014 03 20

## Installing

Have a modern setuptools or pip installed.

While:

    easy_install cocos2d

or:

    pip install cocos2d --process-dependency-links

should work, you will miss the docs and code samples. Its is therefore recommended to

> - download cocos2d-0.6.0.zip from https://pypi.python.org/pypi/cocos2d/

> - decompress to a convenient location, the top dir will be cocos2d-0.6.0

> - the html docs will be in cocos2d-0.6.0/doc/html

> - useful code samples will be in cocos2d-0.6.0/test, cocos2d-0.6.0/samples, cocos2d-0.6.0/utest

> - install by:

>       cd cocos2d-0.6.0
>       setup.py install

>   or alternatively by pointing that directory from a .pth or PYTHONPATH

> - All of cocos should be usable now, with the possible exceptions

>   > - cocos particles
>   > - SDL audio backend
>   > - AVBin (pyglet) audio-video backend

If you want to add these, look at the dependencies section.

## Using PYTHONPATH or .pth

It is safe to point a checkout of cocos from a .pth or PYTHONPATH both
  in python 2.x and 3.x; the same checkout can be pointed at the same time from both pythons.

Remember that pyglet does python 3 compatibility by running 2to3 at install time, so while a pyglet checkout can be pointed from a .pth or PYTHONPATH in python 2.x, that will not work for python 3.
