Load a Sound

Part of the Sound and Game Feel section of Coddy's Pygame journey. Lesson 1 of 23.

pygame plays short sounds through pygame.mixer.Sound. Give it the path of a sound file and you get a Sound object:

jump_sound = pygame.mixer.Sound("assets/sounds/jump.ogg")

pygame.init() starts the mixer, so make your Sounds after it. Make each Sound once, before the loop. Loading reads the file from disk; inside the loop it would read it 60 times a second.

When the moment comes, call play():

jump_sound.play()

play() starts the sound and returns at once. The game keeps running while you hear it, and the same Sound can play again before it ends.

The assets/sounds/ folder holds the sounds you can use: jump, coin, powerup, laser, explosion, hit and more, all .ogg files. Open the Assets tab beside the game to hear them.

Challenge

Easy

The green square jumps when you press Space. Make it play a sound:

Before the loop, load assets/sounds/jump.ogg into jump_sound.
Call jump_sound.play() where the jump starts, next to speed_y = -14.

Try it yourself

import pygame

pygame.init()
screen = pygame.display.set_mode((480, 360))
pygame.display.set_caption("Jump")
clock = pygame.time.Clock()

player = pygame.Rect(220, 280, 40, 40)
speed_y = 0

running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_SPACE and player.bottom == 320:
                speed_y = -14

    speed_y += 1
    player.y += speed_y
    if player.bottom > 320:
        player.bottom = 320
        speed_y = 0

    screen.fill((30, 30, 46))
    pygame.draw.rect(screen, (80, 80, 100), (0, 320, 480, 40))
    pygame.draw.rect(screen, (90, 200, 120), player)
    pygame.display.flip()
    clock.tick(60)

pygame.quit()
