These examples should help get you started with pygame. Here is a brief rundown of what you get. The source code for these examples is in the public domain. Feel free to use for your own projects.
There are several ways to run the examples. First they can be run as stand-alone programs. Second they can be imported and their main() methods called (see below). Finally, the easiest way is to use the python -m option:
python -m pygame.examples.<example name> <example arguments>
python -m pygame.examples.scaletest someimage.png
Resources such as images and sounds for the examples are found in the pygame/examples/data subdirectory.
You can find where the example files are installed by using the following commands inside the python interpreter.
>>> import pygame.examples.scaletest >>> pygame.examples.scaletest.__file__ '/usr/lib/python2.6/site-packages/pygame/examples/scaletest.py'
On each OS and version of python the location will be slightly different. For example on windows it might be in ‘C:/Python26/Lib/site-packages/pygame/examples/’ On Mac OS X it might be in ‘/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/pygame/examples/’
You can also run the examples in the python interpreter by calling each modules main() function.
>>> import pygame.examples.scaletest >>> pygame.examples.scaletest.main()
We’re always on the lookout for more examples and/or example requests. Code like this is probably the best way to start getting involved with python gaming.
examples as a package is new to pygame 1.9.0. But most of the examples came with pygame much earlier.
This started off as a port of the SDL demonstration, Aliens. Now it has evolved into something sort of resembling fun. This demonstrates a lot of different uses of sprites and optimized blitting. Also transparency, colorkeys, fonts, sound, music, joystick, and more. (PS, my high score is 117! goodluck)
This more closely resembles a port of the SDL Aliens demo. The code is a lot simpler, so it makes a better starting point for people looking at code for the first times. These blitting routines are not as optimized as they should/could be, but the code is easier to follow, and it plays quick enough.
A simple starfield example. You can change the center of perspective by leftclicking the mouse on the screen.
This simple example is derived from the line-by-line tutorial that comes with pygame. It is based on a ‘popular’ web banner. Note there are comments here, but for the full explanation, follow along in the tutorial.
This is the full and final example from the Pygame Tutorial, “How Do I Make It Move”. It creates 10 objects and animates them on the screen.
Note it’s a bit scant on error checking, but it’s easy to read. :] Fortunately, this is python, and we needn’t wrestle with a pile of error codes.
Super quick, super simple application demonstrating the different ways to render fonts with the font module
Demonstrates creating a vertical gradient with pixelcopy and NumPy python. The app will create a new gradient every half second and report the time needed to create and display the image. If you’re not prepared to start working with the NumPy arrays, don’t worry about the source for this one :]
Eventlist is a sloppy style of pygame, but is a handy tool for learning about pygame events and input. At the top of the screen are the state of several device values, and a scrolling list of events are displayed on the bottom.
This is not quality ‘ui’ code at all, but you can see how to implement very non-interactive status displays, or even a crude text output control.
Another example filled with various surfarray effects. It requires the surfarray and image modules to be installed. This little demo can also make a good starting point for any of your own tests with surfarray
If arraytype is provided then use that array package. Valid values are ‘numeric’ or ‘numpy’. Otherwise default to NumPy, or fall back on Numeric if NumPy is not installed. As a program surfarray.py accepts an optional –numeric or –numpy flag. (New pygame 1.9.0)
Extremely basic testing of the mixer module. Load a sound and play it. All from the command shell, no graphics.
If provided, use the audio file ‘file_path’, otherwise use a default file.
sound.py optional command line argument: an audio file
If arraytype is provided then use that array package. Valid values are ‘numeric’ or ‘numpy’. Otherwise default to NumPy, or fall back on Numeric if NumPy is not installed.
Uses sndarray and NumPy ( or Numeric) to create offset faded copies of the original sound. Currently it just uses hardcoded values for the number of echos and the delay. Easy for you to recreate as needed. Run as a program sound_array_demos.py takes an optional command line option, –numpy or –numeric, specifying which array package to use.
This example was created in a quick comparison with the BlitzBasic gaming language. Nonetheless, it demonstrates a quick 8-bit setup (with colormap).
Using PyOpenGL and pygame, this creates a spinning 3D multicolored cube.
A simple demonstration example for the clipboard support.
one or more image file names.
This pygame.masks demo will display multiple moving sprites bouncing off each other. More than one sprite image can be provided.
If run as a program then mask.py takes one or more image files as command line arguments.
Optional keyword arguments:
update_rects - use the RenderUpdate sprite group class use_static - include non-moving images use_FastRenderGroup - Use the FastRenderGroup sprite group screen_dims - pygame window dimensions use_alpha - use alpha blending flags - additional display mode flags
Like the testsprite.c that comes with sdl, this pygame version shows lots of sprites moving around.
If run as a stand-alone program then no command line arguments are taken.
fin - name of an input image file fout - name of the output file to create/overwrite w, h - size of the rescaled image, as integer width and height
How to use pygame with no windowing system, like on headless servers.
Thumbnail generation with scaling is an example of what you can do with pygame.
NOTE: the pygame scale function uses mmx/sse if available, and can be run in multiple threads.
If headless_no_windows_needed.py is run as a program it takes the following command line arguments:
-scale inputimage outputimage new_width new_height eg. -scale in.png outpng 50 50
This is a stress test for the fastevents module.
- Fast events does not appear faster!
So far it looks like normal pygame.eventpygame module for interacting with events and queues is faster by up to two times. So maybe fastevent isn’t fast at all.
Tested on windowsXP sp2 athlon, and freebsd.
However... on my debian duron 850 machine fastevents is faster.
Play the .pgm video fila a path fname.
If run as a program overlay.py takes the file name as a command line argument.
A interactive demo that lets one choose which BLEND_xxx option to apply to a surface.
Fake additive blending. Using NumPy. it doesn’t clamp. Press r,g,b Somewhat like blend_fill.
Display an arrow or circle with crossbar cursor.
Display various pixelarray generated effects.
imagefile - file name of source image (required) convert_alpha - use convert_alpha() on the surf (default False) run_speed_test - (default False)
A smoothscale example that resized an image on the screen. Vertical and horizontal arrow keys are used to change the width and height of the displayed image. If the convert_alpha option is True then the source image is forced to have source alpha, whether or not the original images does. If run_speed_test is True then a background timing test is performed instead of the interactive scaler.
If scaletest.py is run as a program then the command line options are:
ImageFile [-t] [-convert_alpha] [-t] = Run Speed Test [-convert_alpha] = Use convert_alpha() on the surf.
mode - if 'output' run a midi keyboard output example 'input' run a midi event logger input example 'list' list available midi devices (default 'output') device_id - midi device number; if None then use the default midi input or output device for the system
The output example shows how to translate mouse clicks or computer keyboard events into midi notes. It implements a rudimentary button widget and state machine.
The input example shows how to translate midi input to pygame events.
With the use of a virtual midi patch cord the output and input examples can be run as separate processes and connected so the keyboard output is displayed on a console.
new to pygame 1.9.0
This example shows a scrollable image that has a zoom factor of eight. It uses the Surface.scroll() function to shift the image on the display surface. A clip rectangle protects a margin area. If called as a function, the example accepts an optional image file path. If run as a program it takes an optional file path command line argument. If no file is provided a default image file is used.
When running click on a black triangle to move one pixel in the direction the triangle points. Or use the arrow keys. Close the window or press ESC to quit.
A simple movie player that plays an MPEG movie in a Pygame window. It showcases the pygame.moviepygame module for playback of mpeg video module. The window adjusts to the size of the movie image. It is given a border to demonstrate that a movie can play autonomously in a sub- window. Also, the file is copied to a file like object to show that not just Python files can be used as a movie source.
The pygame.moviepygame module for playback of mpeg video module is problematic and may not work on all systems. It is intended to replace it with an ffmpeg based version.
A simple live video player, it uses the first available camera it finds on the system.
