python pygame模块按键延迟_python – Pygame – 声音延迟

我做了一个按钮类,检查是否选中了一个按钮(当鼠标悬停在按钮上时).当选择,未选中或单击按钮时,它将播放一个wav文件.问题是声音播放和按钮状态变化之间存在巨大延迟.该程序应检查每一帧,看看是否已满足播放声音的条件,但fps似乎不是问题(60和600 fps给出相同的延迟).我试过减少pygame.mixer.init()中的缓冲区值,但这也没有显示出差异.

声音文件：

buttonSoundSelect = pygame.mixer.Sound(os.path.join(soundPath, "button1.wav"))

buttonSoundUnselect = pygame.mixer.Sound(os.path.join(soundPath, "button2.wav"))

buttonSoundClick = pygame.mixer.Sound(os.path.join(soundPath, "button3.wav"))

buttonSounds = [buttonSoundSelect, buttonSoundUnselect, buttonSoundClick]

创建对象：

playButton = button(textInactive = "Play", font = mainFont, sounds = buttonSounds, command = playAction)

来自按钮类的代码,用于检查是否选择了按钮(这是在每帧调用的方法.display中)：

if pygame.mouse.get_pos()[0] >= self.x and pygame.mouse.get_pos()[0] <= self.x + self.width and \

pygame.mouse.get_pos()[1] >= self.y and pygame.mouse.get_pos()[1] <= self.y + self.height:

self.surfaceActive.blit(self.textSurfaceActive, (self.width / 2 - self.font.size(self.textActive)[0] / 2,

self.height / 2 - self.font.size(self.textActive)[1] / 2))

self.surface.blit(self.surfaceActive, (self.x, self.y))

if self.selected == False:

if self.sounds != None:

self.sounds[0].stop()

self.sounds[1].stop()

self.sounds[2].stop()

self.sounds[0].play()

self.selected = True

else:

self.surfaceInactive.blit(self.textSurfaceInactive, (self.width / 2 - self.font.size(self.textInactive)[0] / 2,

self.height / 2 - self.font.size(self.textInactive)[1] / 2))

self.surface.blit(self.surfaceInactive, (self.x, self.y))

if self.selected == True:

if self.sounds != None:

self.sounds[0].stop()

self.sounds[1].stop()

self.sounds[2].stop()

self.sounds[1].play()

self.selected = False

来自按钮类的代码,用于检查是否单击了按钮(这是在单击鼠标左键时调用的方法.clickEvent中)：

if self.command != None:

if pygame.mouse.get_pos()[0] >= self.x and pygame.mouse.get_pos()[0] <= self.x + self.width and \

pygame.mouse.get_pos()[1] >= self.y and pygame.mouse.get_pos()[1] <= self.y + self.height:

if self.sounds != None:

self.sounds[2].play()

self.command()

所以我的问题是：

为什么会有很长的延迟,我可以缩短它吗？
