我如何为开始游戏按钮创建一个功能来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创建一个功能，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:        pygame.draw.rect(gameDisplay, ac,(x,y,w,h))    else:        pygame.draw.rect(gameDisplay, ic,(x,y,w,h))        if clikc[0] == 1 and action != None:            action()        else:            pygame.draw.rect(window,ic,(x,y,w,h))    smallText = pygame.font.Font("freesansbold.ttf",20)    textSurf, textRect = text_objects(msg, smallText)    textRect.center = ( (x+(w/2)), (y+(h/2)) )    gameDisplay.blit(textSurf, textRect)#------------------------------------------------------def text_objects(text, font):    textSurface = font.render(text, True, black)    return textSurface, textSurface.get_rect()def game_intro():    red = (200,0,0)    green = (0,200,0)    bright_red = (255,0,0)    bright_green = (0,255,0)    intro = True    while intro:        for event in pygame.event.get():            #print(event)            if event.type == pygame.QUIT:                pygame.quit()                quit()        window.fill((255,255,255))        largeText = pygame.font.Font('BLOODY.ttf',115)        TextSurf, TextRect = text_objects("Stolen Hearts!", largeText)        TextRect.center = ((800/2), (800/2))        window.blit(TextSurf, TextRect)# make the square brighter if collideded with the buttons        mouse = pygame.mouse.get_pos()        if 150+120 > mouse[0] > 150 and 450+50 > mouse[1] > 450:            pygame.draw.rect(window, bright_green,(150,450,120,50))        else:            pygame.draw.rect(window, green,(150,450,120,50))        if 550+110 > mouse[0] > 550 and 450+50 > mouse[1] > 450:            pygame.draw.rect(window, bright_red,(550,450,110,50))        else:            pygame.draw.rect(window, red,(550,450,110,50))我的完整代码脚本

你必须删除错误button()并且你必须button()使用game_intro()

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

def text_objects(text, font):

    image = font.render(text, True, BLACK)

    rect  = image.get_rect()

    return image, rect

def button(window, 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(window, ac,(x,y,w,h))

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

            action()

    else:

        pygame.draw.rect(window, ic,(x,y,w,h))

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

def game_intro():

    while running:

        for event in pygame.event.get():

            if event.type == pygame.QUIT:

                pygame.quit()

                quit()

        window.fill((255,255,255))

        image, rect = text_objects("Stolen Hearts!", large_font)

        rect.center = (400, 400)

        window.blit(image, rect)

        button(window, "Start Game", 150, 450, 120, 50, GREEN, BRIGHT_GREEN, main_game)

        button(window, "Quit Game",  350, 450, 120, 50, RED, BRIGHT_RED, quit_game)

        pygame.display.update()

        clock.tick(15)

def main_game():

    running = True

    while running:

        for event in pygame.event.get():

            if event.type == pygame.QUIT:

                pygame.quit()

                quit()

        window.fill((255,255,255))

        image, rect = text_objects("Main Game", large_font)

        rect.center = (400, 400)

        window.blit(image, rect)

        button(window, "Intro",     550, 450, 120, 50, GREEN, BRIGHT_GREEN, game_intro)

        button(window, "Quit Game", 350, 450, 120, 50, RED, BRIGHT_RED, quit_game)

    quit()

# --- main ---

pygame.init()

window = pygame.display.set_mode((800, 800))

# 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

• 所有常量值直接放在一个地方imports，它们使用UPPER_CASE_NAMES(PEP8) 和

• 所有类都在一个地方 - 直接在常量之后和之前pygame.init()- 他们使用CamelCaseNames（PEP8）

• 所有功能都在一个地方 - 课后和课前pygame.init()- 他们使用lower_case_names（PEP8）
