Adding Music

In this lesson, you’ll add background music to your game. The sounds and music you will use in this lesson and the next are in the sound directory:


Sample Code (.zip)

As with most things in pygame, using mixer starts with an initialization step:

 98 # Setup for music and sounds. Defaults are good.
 99 pygame.mixer.init()
101 # Initialize pygame
102 pygame.init()

After the system is initialized, you can get your background music setup:

129 # Load and play background music
130 # Sound source: Chris Bailey - artist Tripnet
131 # License:

Finally, when the game is over, all sounds should stop. This is true whether the game ends due to a collision or the user exits manually. To do this, add the following lines at the end of the program after the loop:

193 # All done! Stop and quit the mixer.
195 pygame.mixer.quit()

For more information about the music module, mixer, and .mixer.init(), check out the following resources from the pygame documentation:

Sky_dodge_theme.ogg file is not in the folder via the link provided.

Nevermind! I found it when I downloaded the Code zip file under Suppporting Materials.

Same here! Thank @helenyip2 for pointing the references to files.

Well, maybe I’m missing something. When I click on “Click here to download the source code for the PyGame sample project used in this tutorial.” I’m taken to a github page called realpython/materials/pygame-a-primer.

In there I see a list of 14 files. There’s the ‘cloud.png’, ‘jet.png’, and ‘missile.png’ image files we used in an earlier lesson. But no ‘Sky_dodge_theme.ogg’ or any zip file that might contain it. I do see ‘collision.ogg’, ‘Rising_putter.ogg’ and ‘Falling_putter.ogg’, but I suppose those are for the upcoming ‘Adding Sound Effects’ lesson? There is an mp3 called ‘Apaxode-Electric_1.mp3’ which I presume is to be used as background music?

The other files I have no idea what to do with.

Hi @jamesbrown68, At the top of the description text for this lesson, just below the video player, you will see a button for “Supporting Material”. You can download a .zip file from there which has the code broken up into the individual lessons, and separate folders for images and sound.

Thanks, Chris.

Am I crazy? Was that link there yesterday? I’m probably crazy.
