Question

所以我正在制作2D游戏，我想显示一个获胜的文本，每次我到达屏幕底部（这就是我赢得游戏的方式）时，游戏只会冻结并且不显示我的文本。虽然可以重置，但可以像我想要的那样回到开始

#this is where I set up my text and font

# def text_objects(text, font):
   # textSurface = font.render(text, True, BLACK)
   # return textSurface, textSurface.get_rect()

#def message_dissplay(text):
  #  largeText = pygame.font.Font("freesansbold.ttf", 115)
   # TextSurf, TextRect = text_objects(text, largeText)
   # TextRect.center = ((SCREEN_WIDTH/2), (SCREEN_HEIGHT/2))
   # gameDisplay.blit(TextSurf, TextRect)

    #time.sleep(2)

   # main()

#def GameWon():
 #   message_dissplay("You Won")

  #this is the mainloop I use for my game
#def main():
   # pygame.init()

    # Set the height and width of the screen
   # size = [SCREEN_WIDTH, SCREEN_HEIGHT]
   # screen = pygame.display.set_mode(size)


    # Main Loop
    while not done:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                done = True

          #I set up my code so if the player reached 750 pixles he gets 
           #reset to 
           #the top and 

         #I want it to display a win text

        if player.rect.y > 750:
            GameWon()

我真的很困惑如何在遇到获胜条件时向游戏中添加文字

draw() blit()仅发送到缓冲区。您忘记了pygame.screen.update()或pygame.screen.flip()将图形从缓冲区发送到显示它的视频卡。

您GameWon()使用sleep()，因此游戏无法运行for event循环并移动/单击或按下鼠标键。它也无法运行pygame.screen.update()来在屏幕上发送图形-然后看起来像冻结了。

在示例中，我使用state在主循环中运行不同的代码-简介，游戏，游戏结束等。我还使用计时器而不是sleep进行控制，因此它不会停止循环。

我使用外部main()而不是再次运行loop，因此游戏可以退出旧循环，重置设置并再次运行旧循环。这样，我不必再次运行main（）。

def text_objects(text, font):
    textSurface = font.render(text, True, BLACK)
    return textSurface, textSurface.get_rect()

def message_dissplay(text):
    largeText = pygame.font.Font("freesansbold.ttf", 115)
    TextSurf, TextRect = text_objects(text, largeText)
    TextRect.center = ((SCREEN_WIDTH/2), (SCREEN_HEIGHT/2))
    #TextRect.center = screen.get_rect().center
    gameDisplay.blit(TextSurf, TextRect)

def main():
    pygame.init()

    # Set the height and width of the screen
    size = [SCREEN_WIDTH, SCREEN_HEIGHT]
    screen = pygame.display.set_mode(size)

    # Main Loop
    repeate_game = True:

    while repeate_game:

        reset_game() # set default values again
        state = 'game' #'intro'

        done = False
        while not done:
            for event in pygame.event.get():
                if event.type == pygame.QUIT:
                    done = True

            current_time = pygame.time.get_ticks()

            if state = 'intro'
                # here code for intro

            elif state = 'game'
                # here code for game

                if player.rect.y > 750:
                    state = 'gameover'
                    state_end = current_time + 2000 #2000ms = 2s

            elif state = 'pause'
                # here code for pause

                message_dissplay("Pause")

            elif state = 'gameover'
                # here code for Game Over

                message_dissplay("You Won")

                if current_time > state_end:
                    done = True # to exit `while done` after 2000 ms

            # send buffer to video card and on screen 
            pygame.screen.flip() # or pygame.screen.update()
