本文為大家分享了pygame游戲之旅的第9篇，供大家參考，具體內容如下

在游戲開始之前定義一個函數，用來顯示游戲介紹：

def game_intro():  intro = True  while intro:    for event in pygame.event.get():      print(event)      if event.type == pygame.QUIT:        pygame.quit()        quit()    gameDisplay.fill(white)    largeText = pygame.font.Font('freesansbold.ttf',115)    TextSurf, TextRect = text_objects('A bit Racey', largeText)    TextRect.center = ((display_width/2),(display_height/2))    gameDisplay.blit(TextSurf, TextRect)    pygame.display.update()    clock.tick(15)

全部代碼：
