P88 运行后为啥点击键盘空格键后没有切换图标

就看这个部分吧
    if pause:
      screen.blit(pause_image,pause_rect)
      pygame.mixer.music.pause()
    else:
      screen.blit(pause_image,pause_rect)
      pygame.mixer.music.unpause()
没发现吗？每一次无论是暂停或者怎么滴都是画pause_image
只用把不暂停的图标改成unpause就可以啦
修改后代码：

import pygame
import sys
from pygame.locals import *

pygame.init()
pygame.mixer.init()

pygame.mixer.music.load('1.mp3')
pygame.mixer.music.set_volume(0.2)
pygame.mixer.music.play()

cat_sound = pygame.mixer.Sound('2.wav')
cat_sound.set_volume(0.2)
dog_sound = pygame.mixer.Sound('3.wav')
dog_sound.set_volume(0.2)


bg_size = width,height = 600,400
screen = pygame.display.set_mode(bg_size)
pygame.display.set_caption('Music - FishC Demo')

pause = False

pause_image = pygame.image.load('zt.png').convert_alpha()
unpause_image = pygame.image.load('bf.png').convert_alpha()
pause_rect = pause_image.get_rect()
pause_rect.left,pause_rect.top = (width - pause_rect.width) // 2,(height - pause_rect.height) //2

clock = pygame.time.Clock()

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

      if event.type == MOUSEBUTTONDOWN:
            if event.button == 1:
                cat_sound.play()
            if event.button ==3:
                dog_sound.play()

      if event.type == KEYDOWN:
            if event.key == K_SPACE:
                pause = not pause

    screen.fill((255,255,255))

    if pause:
      screen.blit(pause_image,pause_rect)
      pygame.mixer.music.pause()
    else:
      screen.blit(unpause_image,pause_rect)
      pygame.mixer.music.unpause()

    pygame.display.flip()

    clock.tick(30)
