Pysteroids
Pysteroids is an Asteroids clone written in Python and using the Pyglet multimedia library. All of the graphics are done via OpenGL calls exposed by Pyglet, no images are used. I wanted to capture the 'retro' feel of playing Asteroids on Atari or Intellivision or whatever, as well as practice applying some mathematics to programming (mostly in the form of linear algebra and the separating axis theorem). All of the sounds were created using sfxr.
Essentially all of the code is written by me, but I might've adapted some sample code for collision and such, because math is really hard.
Installing
Pysteroids is available from PyPI, and can be installed using pip by running
pip install pysteroids
Setuptools should automatically pull down any dependencies. You also need to have either OpenAL or AVBin installed for audio to work.
Pip should put an entry point called 'pysteroids' in /usr/bin on Mac and Linux and the Python 'Scripts' folder on Windows, which you can then run to start the game.
Controls
- W: move forward
- A/D: rotate
- Space: shoot
- Shift: teleport
Dependencies
Pysteroids uses Python 2.7 and depends on the following Python libraries:
- Numpy (>= 1.7.1)
- Pyglet (> 1.4.1, specifically 1.2alpha1)
Again, Setuptools should pull these down automatically when you install Pysteroids.
Pysteroids uses a Pyglet alpha version instead of the version on PyPI (1.1.4) because of an issue with Pyglet 1.1.4 not initializing correctly on some systems, described here. The patch for this issue is in the current development version (1.2alpha1), but has not been backported to 1.1.4. Development of Pyglet seems to be at a standstill at the moment, so this is the best solution I could come up with.
If you don't want to update, you can get the source from PyPI and modify setup.py by changing
install_requires = ['numpy>=1.7.1',
'pyglet>1.1.4']
to
install_requires = ['numpy>=1.7.1',
'pyglet==1.1.4']
and removing the line
dependency_links = ['http://pyglet.googlecode.com/files/' +
'pyglet-1.2alpha1.tar.gz#egg=pyglet-1.2alpha1'],
Then get the dependencies from pip:
pip install numpy pyglet
And finally, install with
python setup.py install
Be warned that you may get the same error described above if you try this.
