Pymunk is a easy-to-use pythonic 2d physics library that can be used whenever you need 2d rigid body physics from Python. Perfect when you need 2d physics in your game, demo or other application! It is built on top of the very capable 2d physics library Chipmunk.

The first version was released in 2007 and Pymunk is still actively developed and maintained today.

Pymunk has been used with success in many projects, big and small. For example: 3 Pyweek game competition winners, more than a dozen published scientific papers and even in a self-driving car simulation! See the Showcases section on the Pymunk webpage for some examples.

The easiest way to install Pymunk is with pip install:
pip install pymunk -U
It has one direct dependency. CFFI.

For full docs, examples and updates, go to www.pymunk.org!

The release list here is not always up to date. Make sure to use pip install as described above, or visit the Pymunk homepage for the latest version!

Changes

The main goal of this release is to ensure a compatible version of CFFI is installed when installing Pymunk though pip. Unfortunately there is a problem on Linux with CFFI 1.13.1. (Later and earlier versions will work fine).

Changes:

    Added a requirement on CFFI to not be 1.13.1 (since 1.13.1 doesnt work).
    Update cffi definitions to prevent deprecation warning in latest cffi.
    Added normal property to Arbiter object.
    Remove compiled docs from committed code.
    Removed build/test of CPython 3.4 from Travis and Appveyor configs since its not supported anymore.
    Update pyglet examples to work with pyglet 1.4.
    Fixed minor issue in platformer example.
    Improved docs.

If you are using pymunk you might be happy to hear that a new (major) release of pymunk is coming soon. In case you have some time over during the next couple of days, please give the latest svn version of pymunk a try and give me some comments on how it feels. Check this post I made on the chipmunk forums for a little more details: http://www.slembcke.net/forums...

hi,
on apple python I get an error...
OSError: dlopen(/Library/Python/2.6/site-packages/pymunk/libchipmunk.dylib, 6): image not found
It seems libchipmunk.so is there instead. I installed with python setup.py install
cheers,

Problem is that I don't ship the libchipmunk.dylib file with pymunk. Therefor you have to compile it yourself, with the build_chipmunk command (and after that you might need to rerun the install):
>python setup.py build_chipmunk
Right now I only have a MS Vista laptop, together with a Win Server 2008 machine at work, so Im only able to copmile Chipmunk on Windows and Linux, meaning I can include a .dll for windows, and a .so file for 32bit linux. (Linux running in virtual box VM, unfortunately its not possible to run OSX hosted as a VM in a good way because of Apples restrictions).
I wonder if you got an error message with roughly this explanation when it failed? I think I have some code for it, but it would be good to hear if it works in practive, and if/how I can improve it to make it more obvious for users?
