python - 游戏错误 : mixer system not initialized

Question

我刚刚开始了一个小游戏项目，我试图让它在每次发射子弹时都播放声音，但我总是遇到同样的错误:

pygame.error: mixer system not initialized

我不明白我做错了什么，所以这是我的代码:

import pygame, sys
from pygame.locals import *

theClock = pygame.time.Clock()

sound = pygame.mixer.Sound("bullet.mp3")

....

if event.type == KEYDOWN:
    if event.key == K_SPACE and shot_count == 0:
        sound.play()
        shot_y = h-50
        shot_x = x
    elif event.type == K_SPACE and shot_count == 1:
        shot_y_2 = h-50
        shot_x_2 = x
    print(h, ' ', shot_y, shot_count)
if event.type == KEYUP:
    if event.key == K_SPACE and shot_count == 0:
        resetShot = 0 
    elif event.type == K_SPACE and shot_count == 1:
        resetShot = 0

在使用混音器/声音对象之前，您需要pygame.init()。

根据 documentation ，您应该使用 OGG 或 WAV 声音文件。
