本文为大家分享了pygame游戏之旅的第5篇，供大家参考，具体内容如下

在游戏中添加显示文字：

这里自己定义一个crash函数接口：

def crash(): message_diaplay('You Crashed')

然后实现接口函数message_display(text)

def message_diaplay(text): largeText = pygame.font.Font('freesansbold.ttf',115) TextSurf, TextRect = text_objects(text, largeText) TextRect.center = ((display_width/2),(display_height/2)) gameDisplay.blit(TextSurf, TextRect) pygame.display.update() time.sleep(2) game_loop()

在这其中定义了一个函数text_objects(text, largeText)，最后实现这个函数即可

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

全部代码：

import pygameimport time pygame.init() white = (255,255,255) car_width = 100 display_width = 800display_height = 600  gameDisplay = pygame.display.set_mode( (display_width,display_height) )pygame.display.set_caption('A bit Racey')clock = pygame.time.Clock() carImg = pygame.image.load('car.png') def car(x, y): gameDisplay.blit(carImg, (x,y))  def text_objects(text, font): textSurface = font.render(text, True, white) return textSurface, textSurface.get_rect() def message_diaplay(text): largeText = pygame.font.Font('freesansbold.ttf',115) TextSurf, TextRect = text_objects(text, largeText) TextRect.center = ((display_width/2),(display_height/2)) gameDisplay.blit(TextSurf, TextRect) pygame.display.update() time.sleep(2) game_loop() def crash(): message_diaplay('You Crashed')  def game_loop(): x = display_width * 0.45 y = display_height * 0.8 x_change = 0  gameExit = False  while not gameExit:  for event in pygame.event.get():   if event.type == pygame.QUIT:    gameExit = True   if event.type == pygame.KEYDOWN:    if event.key == pygame.K_LEFT:     x_change = -5    elif event.key == pygame.K_RIGHT:     x_change = 5   if event.type == pygame.KEYUP:    if event.key == pygame.K_LEFT or event.key == pygame.K_RIGHT:     x_change = 0   print(event)  x += x_change  gameDisplay.fill(white)  car(x,y)  if x > display_width - car_width or x < 0:   gameExit = True  pygame.display.update()  clock.tick(60)crash()#game_loop()pygame.quit()quit()
