Question

因此，我一直在创建此游戏，并且我正在从加载屏幕过渡到主菜单屏幕，到目前为止，加载屏幕确实可以很好地过渡到主菜单屏幕，但是我不确定如何播放音乐进入主菜单屏幕。我尝试了一种方法，但结果只是音乐从一开始就不断播放。

我制作了一个名为“主菜单”的功能，该功能在背景上显示主菜单的图片，我也尝试定义变量并在同一功能上播放音乐文件。

#Importing some stuff...

#initialising python
pygame.init()
#pygame.mixer.init()
pygame.mixer.pre_init(44100,16,2,4096)
mixer.init()

#define display
W, H = 1600,900
HW, HH = (W/2), (H/2)
AREA = W * H

#MusicBoolean
MenuMusic = pygame.mixer.music.load("MainMenu.mp3")
MenuMusic = pygame.mixer.music.set_volume(0.45)


#initialising display
CLOCK = pygame.time.Clock()
DS = pygame.display.set_mode((W, H))
pygame.display.set_mode((0, 0), pygame.FULLSCREEN)
FPS = 54
progress = 0
background = pygame.Surface(DS.get_size())
smallfont = pygame.font.SysFont("century gothic",25)


#background image
bg = pygame.image.load("Daytime.jpg").convert()
loadingimg = pygame.image.load("LoadingScreen.png").convert()
pause = pygame.image.load("Pause screen.png").convert()

mainmenu = pygame.image.load("Main_Menu4.png").convert()
#mainmenu = pygame.transform.smoothscale(mainmenu, (W,H))

#define some colours
BLACK = (0,0,0,255)
WHITE = (255,255,255,255)
green = (0,140,0)
grey = (180,180,180)



def text_objects(text, color, size):
    if size == "small":
        textSurface = smallfont.render(text, True, color)

    return textSurface, textSurface.get_rect()

def loading(progress):
    if progress < 100:
        text = smallfont.render("Loading: " + str(int(progress)) + "%", True, WHITE)
    else:
        text = smallfont.render("Loading: " + str(100) + "%", True, WHITE)

    DS.blit(text, [50, 660])

def message_to_screen(msh, color, y_displace = 0, size = "small"):
    textSurf, textRect = text_objects(msg, color, size)
    textRect.center = HW, HH + y_displace
    DS.blit(textSurf, textRect)

while (progress/4) < 100:
    event_handler()
    DS.blit(loadingimg, (0,0))
    time_count = (random.randint(1,1))
    increase = random.randint(1,20)
    progress += increase
    pygame.draw.rect(DS, green, [50, 700, 402, 29])
    pygame.draw.rect(DS, grey, [50, 701, 401, 27])
    if (progress/4) > 100:
        pygame.draw.rect(DS, green, [50, 700, 401, 28])
    else:
        pygame.draw.rect(DS, green, [50, 700, progress, 28])
    loading(progress/4)
    pygame.display.flip()

    time.sleep(time_count)


def main_menu():
    DS.blit(mainmenu, (0, 0))
    pygame.display.update()
    MenuMusic = pygame.mixer.music.play()


#mainloop
while run:
    #some code...    
    main_menu()

由于启动主菜单过渡效果很好，我希望主菜单开始在其上播放背景音乐。但是，相反，我要么在后台播放奇怪的声音，要么根本没有声音播放，而且python / pygame shell也没有给出错误。

在pygame中播放音乐
