Question

出于某种原因，我的背景不会改变，并且当按下空格键时我的游戏不会启动。我没有收到任何错误，该程序无法正常工作。请帮忙。

def main():
    title = games.load_image("contratitle.bmp",transparent = False)
    games.screen.background = title
    cursor = Cursor()
    games.screen.add(cursor)
    xd = 0
    if games.keyboard.is_pressed(games.K_q):
        xd = 1        
        while xd == 1:
            screen = games.load_image("jungle.bmp", transparent = False)
            games.screen.background = screen
            file2 = 'contra.mp3'
            pygame.mixer.music.load(file2)
            pygame.mixer.music.play()
            rizer = Rizer()
            games.screen.add(rizer)
            runner = Runner()
            games.screen.add(runner)
            shooter = Shooter()
            games.screen.add(shooter)
            spreadpower = Spreadp()
            #games.screen.add(spreadpower)
            rizerlives = Rizerlives()
            games.screen.add(rizerlives)
            rizerlivesa = Rizerlivesa()
            games.screen.add(rizerlivesa)
            #bean = Bean()
            #games.screen.add(bean)
    games.screen.mainloop()
main()

然后，我尝试使用pygame.display.update（），但这也不起作用。我把它放在错误的地方吗？

def main():
    screen = games.load_image("contratitle.bmp",transparent = False)
    games.screen.background = screen
    cursor = Cursor()
    games.screen.add(cursor)
    xd = 0
    if games.keyboard.is_pressed(games.K_SPACE):
        xd = 1
        while xd == 1:
            screen = games.load_image("jungle.bmp", transparent = False)
            games.screen.background = screen
            file2 = 'contra.mp3'
            pygame.mixer.music.load(file2)
            pygame.mixer.music.play()
            rizer = Rizer()
            games.screen.add(rizer)
            pygame.display.update()
    games.screen.mainloop()
main()

对于您的第7行代码：

if games.keyboard.is_pressed(games.K_q):

您似乎需要将其更改为：

if games.keyboard.is_pressed(games.K_SPACE):
