当我使用PyGame死亡时，除了箭头键以外的所有键都不起作用

Question

我正在用Python编写基本游戏“蛇”，使用“pygame”。当我在开始时四处走动并且还活着时，我的箭头键工作正常。当我死亡时，我不能使用任何键，我不能通过按下窗口右上角的X按钮来关闭窗口。终止它的唯一方法是在控制台中按Ctrl-x，这样它就不会关闭

当我调试它时，我的控制台说我的q和c值是59，248相应地，但是pygameK_q和{}有值113，99.有人知道原因吗？我死后的代码如下：

            while game_close == True:
            self.dis.fill(colors("blue"))
            self.message("You Lost! Press C-Play Again or Q-Quit", colors("red"))
            self.Your_score(Length_of_snake - 1)
            pygame.display.update()
            for event in pygame.event.get():
                if event.type == pygame.KEYDOWN:
                    if event.key == pygame.K_q:
                        game_over = True
                        game_close = False
                    elif event.key == pygame.K_c:
                        game_close = False
                        self.gameLoop()
           

如果有人知道为什么会发生这种情况，这将是有用的。 这是我第一次写任何任务，很抱歉没有最好的描述，或者有任何重复（我搜索了，没有找到适合我的）

编辑：这是整个脚本：

    game_over = False
    game_close = False
    x1 = self.dis_width / 2
    y1 = self.dis_height / 2

    x1_change = 0
    y1_change = 0

    snake_List = []
    Length_of_snake = 1

    foodx = round(random.randrange(0, self.dis_width - self.snake_block) / 10.0) * 10.0
    foody = round(random.randrange(0, self.dis_height - self.snake_block) / 10.0) * 10.0
    
    flagex=True
    flagey=True

    while not game_over:

        while game_close :
            self.dis.fill(colors.blue())
            self.message("You Lost! Press C-Play Again or Q-Quit", colors.red())
            self.Your_score(Length_of_snake - 1)
            pygame.display.update()

            for event in pygame.event.get():
                if event.type == pygame.QUIT:
                    game_close = True
                    game_over = True
                if event.type == pygame.KEYDOWN:
                    if event.key == pygame.K_q:
                        game_over = True
                        game_close = False
                    elif event.key == pygame.K_c:
                         game_close = False
                         self.gameLoop()

                if event.key == pygame.K_LEFT and flagey==True:
                    flagey = False
                    flagex = True
                    x1_change = -self.snake_block
                    y1_change = 0
                elif event.key == pygame.K_RIGHT and flagey==True: 
                    flagey = False
                    flagex = True
                    x1_change = self.snake_block
                    y1_change = 0
                elif event.key == pygame.K_UP and flagex==True:

                    y1_change = -self.snake_block
                    x1_change = 0
                elif event.key == pygame.K_DOWN and flagex==True:
                    flagey = True
                    flagex = False
                    y1_change = self.snake_block
                    x1_change = 0

        if x1 >= self.dis_width or x1 < 0 or y1 >= self.dis_height or y1 < 0:
            game_close = True
        x1 += x1_change
        y1 += y1_change
        self.dis.fill(colors.blue())
        pygame.draw.rect(self.dis, colors.green(), [foodx, foody, self.snake_block, self.snake_block])
        snake_Head = []
        snake_Head.append(x1)
        snake_Head.append(y1)
        snake_List.append(snake_Head)
        if len(snake_List) > Length_of_snake:
            del snake_List[0]

        for x in snake_List[:-1]:
            if x == snake_Head:
                game_close = True

        self.our_snake(self.snake_block, snake_List)
        self.Your_score(Length_of_snake - 1,)

        pygame.display.update()

        if x1 == foodx and y1 == foody:
            foodx = round(random.randrange(0, self.dis_width - self.snake_block) / 10.0) * 10.0

            Length_of_snake += 1

        self.clock.tick(self.snake_speed)

    pygame.quit()
    quit()

我无法完全回答您的问题，因为看到完整的代码会很好，但我会将其更改为：

        while game_close:
            self.dis.fill(colors("blue"))
            self.message("You Lost! Press C-Play Again or Q-Quit", colors("red"))
            self.Your_score(Length_of_snake - 1)
            pygame.display.update()
            for event in pygame.event.get():
                if event.type == pygame.QUIT:
                    game_close = True
                    game_over = True
                    # exit()
            keys = pygame.key.get_pressed()
            if keys[pygame.K_q]:
                game_over = True
                game_close = False
            if keys[pygame.K_c]:
                game_close = False
                self.gameLoop()

试着换成这个

           for event in pygame.event.get():
                if event.type == pygame.KEYUP:
                    if event.key == pygame.K_q:
                        game_over = True
                        game_close = False
                    elif event.key == pygame.K_c:
                        game_close = False
                        self.gameLoop()

Answer 3

未包含整个代码，缺少一个类，并且未定义某些方法。但首先，我建议将所有按键改为：

keys = pygame.key.get_pressed()
if keys[pygame.K_yourkey]:
    # do something
if keys[pygame.K_yourotherkey]:
    # do something
# and so on

不要把它放在循环事件中
