View more ways to use pygame

Pygame is a free and open-source cross-platform library for the development of multimedia applications like video games using Python. It uses the Simple DirectMedia Layer library and several other popular libraries to abstract the most common functions, making writing these programs a more intuitive task.

We need your help to make pygame the best it can be! New contributors are welcome.

Installation

Before installing pygame, you must check that Python is installed on your machine. To find out, open a command prompt (if you have Windows) or a terminal (if you have MacOS or Linux) and type this: :

python --version

If a message such as "Python 3.8.10" appears, it means that Python is correctly installed. If an error message appears, it means that it is not installed yet. You must then go to the official website to download it.

Once Python is installed, you have to perform a final check: you have to see if pip is installed. Generally, pip is pre-installed with Python but we are never sure. Same as for Python, type the following command: :

pip --version

If a message such as "pip 20.0.2 from /usr/lib/python3/dist-packages/pip (python 3.8)" appears, you are ready to install pygame! To install it, enter this command: :

pip install pygame

Once pygame is installed, quickly test your library by entering the following command, which opens one of the many example games that comes pre-installed: :

python3 -m pygame.examples.aliens

If this doesn’t work, the Getting Started section of the official website has more information for platform specific issues, such as adding python to your machine’s PATH settings

Help

If you are just getting started with pygame, you should be able to get started fairly quickly. Pygame comes with many tutorials and introductions. There is also full reference documentation for the entire library. Browse the documentation on the docs page. You can also browse the documentation locally by running python -m pygame.docs in your terminal. If the docs aren't found locally, it'll launch the online website instead.

The online documentation stays up to date with the development version of pygame on GitHub. This may be a bit newer than the version of pygame you are using. To upgrade to the latest full release, run pip install pygame --upgrade in your terminal.

Best of all, the examples directory has many playable small programs which can get you started playing with the code right away.

Features

Pygame is a powerful library for game development, offering a wide range of features to simplify your coding journey. Let's delve into what pygame has to offer:

Graphics - With pygame, creating dynamic and engaging graphics has never been easier. The library provides simple yet effective tools for 2D graphics and animation, including support for images, rectangles, and polygon shapes. Whether you're a seasoned game developer or just starting out, pygame has you covered.

Sound - Pygame also includes support for playing and manipulating sound and music, making it easy to add sound effects and background music to your games. With support for WAV, MP3, and OGG file formats, you have plenty of options to choose from.

Input - Pygame provides intuitive functions for handling keyboard, mouse, and joystick input, allowing you to quickly and easily implement player controls in your games. No more struggling with complex input code, pygame makes it simple.

Game Development - Lastly, pygame provides a comprehensive suite of tools and features specifically designed for game development. From collision detection to sprite management, pygame has everything you need to create exciting and engaging games. Whether you're building a platformer, puzzle game, or anything in between, pygame has you covered.

Building From Source

If you want to use features that are currently in development, or you want to contribute to pygame, you will need to build pygame locally from its source code, rather than pip installing it.

Installing from source is fairly automated. The most work will involve compiling and installing all the pygame dependencies. Once that is done, run the setup.py script which will attempt to auto-configure, build, and install pygame.

Much more information about installing and compiling is available on the Compilation wiki page.

Dependencies

Pygame is obviously strongly dependent on SDL and Python. It also links to and embeds several other smaller libraries. The font module relies on SDL_ttf, which is dependent on freetype. The mixer (and mixer.music) modules depend on SDL_mixer. The image module depends on SDL_image, which also can use libjpeg and libpng. The transform module has an embedded version of SDL_rotozoom for its own rotozoom function. The surfarray module requires the Python NumPy package for its multidimensional numeric arrays. Dependency versions:

License

This library is distributed under GNU LGPL version 2.1, which can be found in the file docs/LGPL.txt. We reserve the right to place future versions of this library under a different license.

This basically means you can use pygame in any project you want, but if you make any changes or additions to pygame itself, those must be released with a compatible license (preferably submitted back to the pygame project). Closed source and commercial games are fine.

The programs in the examples subdirectory are in the public domain.

See docs/licenses for licenses of dependencies.
