你怎么能用屏幕上的文字结束你的游戏？

如何解决你怎么能用屏幕上的文字结束你的游戏？

对于我的多项选择程序，当用户的生命耗尽时，屏幕上会弹出“游戏结束”文本。但是，当我添加此选项时，多项选择选项仍然保留在屏幕上，并且它们仍然可以继续游戏。如果他们继续，“游戏结束”文本会突然消失。

以下是我的代码相关部分的片段：

    def update(self,events,dt):
        for event in events:
            if event.type == pygame.MOUSEBUTTONDOWN:
                n = 1
                for rect in self.rects:
                    if rect.collidepoint(event.pos):
                        self.gamestate.answer(n)
                        if self.gamestate.questions:
                            return ('GAME',self.gamestate)
                        else:
                            quit()
                    n += 1



class QuitScene:
    def __init__(self):
        if SimpleScene.FONT == None:
            SimpleScene.FONT = pygame.freetype.SysFont(None,32)

    def start(self,gamestate):
        self.background = pygame.Surface((1275,775))
        self.background.fill(pygame.Color('white'))
        self.gamestate = gamestate

    def draw(self,screen):
        screen.blit(self.background,(0,0))
        game_over_surf = font100.render("Game Over",True,0))
        screen.blit(game_over_surf,game_over_surf.get_rect(center=screen.get_rect().center))

    def update(self,dt):
        for event in events:
            if event.type == pygame.MOUSEBUTTONDOWN:
                quit()
            if self.gamestate.questions and self.gamestate.lives > 0:
                            return ('GAME',self.gamestate)
            elif self.gamestate.lives == 0:
                        return ('QUIT',)
            n += 1


def main():
    pygame.init()
    screen = pygame.display.set_mode((1275,775))
    clock = pygame.time.Clock()
    dt = 0

    scenes = {
        'TITLE': SimpleScene('SETTING','You have chosen category 1: Introduction to Programming ','','press [SPACE] to start'),'SETTING': SettingScene(),'GAME': GameScene(),'QUIT': QuitScene(),}
    scene = scenes['TITLE']
    while True:
        events = pygame.event.get()
        for e in events:
            if e.type == pygame.QUIT:
                return

        game = scene.update(events,dt)
        if game:
            next_scene,state = game
            if next_scene:
                scene = scenes[next_scene]
                scene.start(state)


        scene.draw(screen)

        pygame.display.flip()
        dt = clock.tick(60)


if __name__ == '__main__':
    main()

有没有办法在生命耗尽时游戏完全停止但“游戏结束”文本会保留在屏幕上？谢谢。

解决方法

如果我正确理解你想要什么，我相信这段代码会对你有所帮助：

我修改了 GameScene 类。在 update 方法中有对 quit() 的调用。该调用将完全关闭应用程序。因此，我添加了一个新场景，即 QuitScene，它在屏幕中显示 Game Over 文本，单击后，应用程序将关闭。如果您不想关闭它，我已经添加了一条注释，指出您必须修改代码以更改该行为的位置。
