Pygame project sound mixing issue...

[Mattyp77]

Im making a tanks game. Left and Right arrow keys move the tank left and right and space bar + ENTER fire a round. I have a sound uploaded for both the tank moving and the sound of heavy artillery being fired. They both work individually but when I press fire while moving the fire does not sound. Only the moving sound continues. However I added a print statement to tell me if it detected the space bar hit and it definitely does every time. I can get two sounds to go at the same time by hitting the space bar and then moving but it doesnt work in the other way. Whats the dil?

Unfortunately It wont let me upload the sound files. I gotta set up a git hub

pygame has a method for assigning different sounds to different channels. You could try that.

Here is a link to example https://stackoverflow.com/questions/38028970/how-to-assign-sounds-to-channels-in-pygame
and the pygame mixer doc https://www.pygame.org/docs/ref/mixer.html

This works for me. You can also uncomment the channels if it doesn't work for you.

# Do the imports
import pygame
import os
from random import random

# Initiate pygame
pygame.init()

# Setup the window
pygame.display.set_mode((800,600))

# Path to executing script
path = os.path.realpath(os.path.dirname(__file__))

# Itialize pygame mixer
pygame.mixer.init(frequency=44100, size=-16, channels=1)

# Sound files
thunder = pygame.mixer.Sound(f'{path}/thunder.mp3')
rain = pygame.mixer.Sound(f'{path}/rain.mp3')

# Create the channels
# channel1 = pygame.mixer.Channel(0)
# channel2 = pygame.mixer.Channel(1)

# Play the rain in a continuous loop
# channel1.play(rain, loops=-1)

rain.play()
run = True
while run:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False


    # Set a random number and compare
    # Play the file if number greater than or equal too random number
    if random() >= .9999:
        # channel2.play(thunder)
        # 6 second delay to allow file to play
        # pygame.time.delay(6000)
        thunder.play()
            

    pygame.display.update()
