Question

我正在尝试在拍照时切换背景音乐当它击中顶部时击中底部并返回第一个。什么时候我试着把它放在while #formula然后它每次都重置它下降了一点，这不是我想要的。你能帮我弄清楚如何编写这段代码：

pygame.mixer.music.load('song1')
pygame.mixer.music.play(-1, 0.0)

pygame.mixer.music.load('song2')
pygame.mixer.music.play(-1, 0.0)

在下面的代码中，并按照我在这里解释的那样切换它？如果我忘了解释你需要知道的事情请告诉我。

import pygame, sys
from pygame.locals import *

pygame.init()

FPS = 200
fpsClock = pygame.time.Clock()

DISPLAYSURF = pygame.display.set_mode((400, 400), 0, 0)
pygame.display.set_caption('Verkefni 21')

WHITE = (255, 255, 255)
clownx = 10
clowny = 10
direction = 'right'
stefna = 'niður'

while True:
DISPLAYSURF.fill(WHITE)
if stefna == 'niður':
    if direction == 'right':
        clownImg = pygame.image.load('sarah.jpg')
        clownx += 5
        if clownx == 320:
            clowny += 10
            direction = 'left'
            clownImg = pygame.image.load('john.jpg')
        if clowny == 300:
            stefna = 'up'
            soundObj = pygame.mixer.Sound('bomb.wav')
            soundObj.play()
            import time
            time.sleep(2) # wait and let the sound play for 1 second
            soundObj.stop()

    elif direction == 'left':
        clownImg = pygame.image.load('john.jpg')
        clownx -= 5
        if clownx == 10:
            clowny += 10
            direction = 'right'
            clownImg = pygame.image.load('sarah.jpg')
        if clowny == 300:
            stefna = 'up'
            soundObj = pygame.mixer.Sound('bomb.wav')
            soundObj.play()
            import time
            time.sleep(2) # wait and let the sound play for 1 second
            soundObj.stop()
elif stefna == 'up':
    if direction == 'right':
        clownImg = pygame.image.load('arnold.jpg')
        clownx += 5
        if clownx == 320:
            clowny -= 10
            direction = 'left'
            clownImg = pygame.image.load('terminator.jpg')
        if clowny == 0:
            stefna = 'niður'
            soundObj = pygame.mixer.Sound('bomb.wav')
            soundObj.play()
            import time
            time.sleep(2) # wait and let the sound play for 1 second
            soundObj.stop()
    elif direction == 'left':
        clownImg = pygame.image.load('terminator.jpg')
        clownx -= 5
        if clownx == 0:
            clowny -=10
            direction = 'right'
            clownImg = pygame.image.load('arnold.jpg')
        if clowny == 0:
            stefna = 'niður'
            soundObj = pygame.mixer.Sound('bomb.wav')
            soundObj.play()
            import time
            time.sleep(2) # wait and let the sound play for 1 second
            soundObj.stop()

DISPLAYSURF.blit(clownImg, (clownx, clowny))

for event in pygame.event.get():
    if event.type == QUIT:
        pygame.quit()
        sys.exit()

pygame.display.update()
fpsClock.tick(FPS)
