Easymunk

Easymunk 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 <http://chipmunk-physics.net>`_.
Easymunk is a fork of the excellent pymunk project, but it allows itself to deviate
more from the original C-library API. The goal is to explore a more Pythonic interface
and tends to be easier to use and require less code to acomplish the same effects.
The first version was released in 2021, based on Pymunk 6.0. It owns greatly from Pymunk's
maturity and 10 years of active development. Easymunk is a laboratory and we hope to
give back code to Pymunk upstream and collaborate with its development.

Installation
------------
In the normal case Easymunk can be installed from PyPI with pip::
> pip install easymunk-physics
It has a few dependencies that are installed automatically.
Example
-------
Quick code example::
import easymunk as mk # Import easymunk.
space = mk.Space( # Create a Space which contain the simulation
gravity=(0, -10), # setting its gravity
)
body = space.create_box( # Create a Body with mass, moment,
shape=(10, 20), # position and shape.
mass=10,
moment=150,
position=(50,100),
)
while True: # Infinite loop simulation
space.step(0.01) # Step the simulation one step forward
space.debug_draw() # Print the state of the simulation
For more detailed and advanced examples, take a look at the included demos
(in examples/).
Examples are not included if you install with `pip install easymunk`. Instead you
need to download the source archive (easymunk-x.y.z.zip). Download available from
https://pypi.org/project/easymunk/#files
Documentation
-------------
The source distribution of Easymunk ships with a number of demos of different
simulations in the examples directory, and it also contains the full
documentation including API reference.
You can also find the full documentation including examples and API reference
on the Easymunk homepage, http://fabiommendes.github.io/easymunk.
The Easymunk Vision
-------------------
"*Make 2d physics easy to include in your game*"
It is (or is striving to be):
* **Easy to use** - It should be easy to use, no complicated code should be
needed to add physics to your game or program.
* **"Pythonic"** - It should not be visible that a c-library (Chipmunk) is in
the bottom, it should feel like a Python library (no strange naming,
no memory handling and more)
* **Simple to build & install** - You shouldn't need to have a zillion of
libraries installed to make it install, or do a lot of command line tricks.
* **Multi-platform** - Should work on both Windows, \*nix and OSX.
* **Non-intrusive** - It should not put restrictions on how you structure
your program and not force you to use a special game loop, it should be
possible to use with other libraries like Pygame and Pyglet.

Dependencies / Requirements
---------------------------
Basically Easymunk have been made to be as easy to install and distribute as
possible, usually `pip install easymunk-physics` will take care of everything for you.
- Python (Runs on CPython 3.8 and later)
- Chipmunk (Compiled library already included on common platforms)
- CFFI (will be installed automatically by Pip)
- Setuptools (should be included with Pip)
* GCC and friends (optional, you need it to compile Easymunk from source. On
windows Visual Studio is required to compile)
* Pygame (optional, you need it to run the Pygame based demos)
* Pyglet (optional, you need it to run the Pyglet based demos)
* Pyxel (optional, you need it to run the Pyxel based demos)
* Streamlit (optional, you need it to run the streamlit based demos)
* Matplotlib & Jupyter Notebook (optional, you need it to run the Matplotlib
based demos)
* Sphinx & aafigure & sphinx_autodoc_typehints (optional, you need it to build
documentation)
Install from source / Chipmunk Compilation
------------------------------------------
This section is only required in case you do not install easymunk from the
prebuild binary wheels (normally if you do not use `pip install` or you are
on a uncommon platform).
Easymunk is built on top of the c library Chipmunk. It uses CFFI to interface
with the Chipmunk library file. Because of this Chipmunk has to be compiled
together with Easymunk as an extension module.
There are basically two options, either building it automatically as part of
installation using for example Pip::
> pip install easymunk-source-dist.zip
And Pip even accepts URL arguments, which can be used to fetch directly a
commit or the latest version in main::
> pip install https://github.com/fabiommendes/easymunk/archive/refs/heads/main.zip
If you want to contribute to this project or simply want to study Easymunk's code,
it is recommended to clone the git repository and build from there::
> git clone http://github.com/fabiommendes/easymunk
After cloning, initialize the repository with git submodules::
> cd easymunk
> git submodule update --init --recursive
This will download the Chipmunk2D source tree, which is necessary to compile the
C-extension module used by easymunk. Now that the source code is available,
build the extension module with::
> python setup.py build_ext
Finally, install it with::
> python setup.py develop --user
Easymunk requires Python 3.8+.
