Python之pygame学习（播放声⾳和⾳效）⽂章⽬录
⼀、相关⽅法
1. pygame.mixer.Sound()：播放⾳效
⾳频可以可以是 OGG ⾳频⽂件或者 WAV ⾳频⽂件
王千源事件2. pygame.mixer.music：播放背景⾳乐
⼆、⽰例1：Music
import pygame
import sys
from pygame.locals import*
pygame.init()
pygame.mixer.init()
pygame.mixer.music.load("bg_music.wav")# 载⼊⾳乐
pygame.mixer.music.set_volume(0.2)# 设置⾳量为 0.2
pygame.mixer.music.play()# 播放⾳乐
dog_sound = pygame.mixer.Sound("dog.wav")
dog_sound.set_volume(0.2)
乌龟组合bird_sound = pygame.mixer.Sound("bird.wav")
bird_sound.set_volume(0.2)
bg_size = width,height =300,200
screen = pygame.display.set_mode(bg_size)
pygame.display.set_caption("Music Demo")
pause =False
pause_imgae = pygame.image.load("pause.png").convert_alpha() unpause_imgae = pygame.image.load("keep.png").convert_alpha()
pause_rect = _rect()
兽兽不雅照片 = width //2,height //2
clock = pygame.time.Clock()
while True:
for event in ():
pe== QUIT:
pe== MOUSEBUTTONDOWN:
# button(1：左键；2：中间键；3：右键)
if event.button ==1:#表⽰点击⿏标左键
dog_sound.play()
if event.button ==3:# 表⽰点击⿏标右键
bird_sound.play()
pe== KEYDOWN:
if event.key == K_SPACE:
pause =not pause
screen.fill((255,255,255))
if pause:
screen.blit(pause_imgae,pause_rect)
else:
screen.blit(unpause_imgae,pause_rect)
pygame.display.flip()
clock.tick(30)
三、⽰例2：给摩擦⼩球游戏添加背景⾳乐和⾳效

# ⾳乐播放完毕，游戏结束
Gameover = USEREVENT # ⾃定义⼀个⽤户事件
pygame.mixer.music.set_endevent(Gameover)
#根据背景图⽚设置游戏界⾯的尺⼨
bg_size = width,height =1024,681
screen = pygame.display.set_mode(bg_size)

while running:
for event in ():

screen.blit(background,(0,0))
for each in balls:

for each in group:
# 检测组中每⼀个⼩球运动过程中是否发⽣碰撞
# 先将其弹出，检测完后再加⼊
# 若发⽣碰撞，就运动⽅向改为相反⽅向
if pygame.sprite.spritecollide(each,group,False,llide_circle): each.speed[0]=-each.speed[0]

group.add(each)
pygame.display.flip()
clock.tick(30)#最⾼每秒不超过 30 次
