我如何为开始游戏按钮制作 Function 以禁用开始屏幕并加载我的主游戏？

Question

所以我在这里有一个游戏介绍，我想知道当我的 *** 鼠标单击开始游戏按钮以禁用 game_intro 时，我该如何制作它？ 它目前没有做任何事情和视频

就像我如何在单击它时为开始按钮制作一个 function，它应该删除 game_intro 或禁用它并加载我的主游戏

这是我现在的游戏介绍

def button(msg,x,y,w,h,ic,ac):
    mouse = pygame.mouse.get_pos()

    if x+w > mouse[0] > x and y+h > mouse[1] > y:

    else:
        pygame.draw.rect(gameDisplay, ic,(x,y,w,h))

您必须删除button()中的错误，并且必须在game_intro()中使用button() )

要解释的太多了，所以我只展示了最少的工作代码。

按钮可以工作，但仍然不理想。 如果新场景在同一个地方有按钮，就会有问题——它会自动点击它——但它需要完全不同的代码。 更多关于GitHub

        pygame.draw.rect(window, ac,(x,y,w,h))
        if click[0] == 1 and action != None:
            action()
    else:

    image = small_font.render(msg, True, BLACK)

# it has to be after `pygame.init()`    
#small_font = pygame.font.Font("freesansbold.ttf", 20)
#large_font = pygame.font.Font('BLOODY.ttf', 115)
small_font = pygame.font.Font(None, 20)
large_font = pygame.font.Font(None, 115)

clock = pygame.time.Clock()

game_intro()

顺便说一句：我也以不同的方式组织代码

• imports后直接将所有常量值放在一个地方，它们使用UPPER_CASE_NAMES (PEP8) 和
• 所有类都在一个地方 - 直接在常量之后和pygame.init()之前 - 他们使用CamelCaseNames (PEP8)
• 所有功能都在一个地方 - 在课程之后和之前pygame.init() - 他们使用lower_case_names (PEP8)
