In Beginner Python, you made a couple of cool games! There's one problem, though: they were completely silent! Today, we're going to learn about making sounds in Python!
Pygame includes a module called pygame.mixer that lets us play sounds. But first, we need a sound to play!
kerblammo = pygame.mixer.Sound("kerblammo.wav")
Once we have a sound, we can press "Play" on it at the appropriate moment:
if alien_spacecraft.just_got_blown_up:
kerblammo.play()
Take the Pong game from Beginner Python and add some sounds to it! If you don't have your Pong code any more, here is a complete game you can use.
On this GitHub page we've included a couple sound files for you to use, which you can download by clicking on them, right-clicking "Raw", and choosing "Save link as...". Put them in the same folder as your program.
The sounds we gave you were boring. Record your own (with Audacity or another program) or download them from a website like Freesound!
Now that we've added sound to our games, it's time for the second step: a cool soundtrack! Pygame gives us pygame.mixer.music, which we can use to stream in some music.
pygame.mixer.music.load("DiscoMonkeysInSpace_soundtrack.mp3")
pygame.mixer.music.play(-1) #-1 means repeat the music forever
One other thing you should know is how to set the volume. If you want a particular sound effect to be much louder than the music, you can try:
pygame.mixer.music.set_volume(0.5) # half volume
kerblammo.set_volume(1.0) #MAXIMUM VOLUME!!!!!!
Add some music to your Pong game! We've given you a track to use, but you can also try and download (or make) your own!
Done with everything else? Here are some more things to try! You might need to use the pygame.mixer documentation to figure some things out yourself.
###Challenge 4: A Unique Sound for Everything
Can you have a different sound for everything that happens in your game: the ball hitting paddle 1, the ball hitting paddle 2, scoring a point, the game starting, the game ending, etc. Get creative!
Make the music fade out at when you close the Pong window!
Try and make something like this in Python.
