Question

此刻我的游戏存在问题，游戏运行正常。然而，当我添加我的主菜单时，它不起作用，它会加载它但是当你按下播放时没有任何事情发生（它不会在游戏中停留在那里）。我附上了简单主菜单的图像（[1]：http://i.stack.imgur.com/YKY9q.jpg）。我的代码如下，谢谢：

看起来您正在关注this tutorial ....

单击“播放”时，您的按钮没有执行任何操作，它只会返回。

def button(msg,x,y,w,h,ic,ac,action=None):

    mouse = pygame.mouse.get_pos()
    click = pygame.mouse.get_pressed()
    if x+w > mouse[0] > x and y+h > mouse[1] > y:
        pygame.draw.rect(screen, (ac), (x, y, w, h))
        if click[0] == 1 and action != None:
            if action == "start":
                return               ### Fix here
            if action == "end":
                pygame.quit()
                sys.exit()

但是，你真的应该为你的行动定义一种方法。

def start_game():
    # TODO: Implement
    print("Starting game")

def how_to_play():
    # TODO: Implement
    print("How to")

def quit_game():
     pygame.quit()
     sys.exit()

在button方法（来自教程）中，您只需要调用该操作。

if x+w > mouse[0] > x and y+h > mouse[1] > y:
    pygame.draw.rect(gameDisplay, ac,(x,y,w,h))

    if click[0] == 1 and action != None:
        action()

然后您可以将方法附加到按钮而不是字符串。

 button("Play",100,300,100,50,green,bright_green,start_game)
 button("Controls",300,300,100,50,orange,bright_orange, how_to_play)
 button("Quit",500,300,100,50,red,bright_red, quit_game)

在游戏循环，Python2和Pygame中实现主菜单
