本文为大家分享了pygame游戏之旅的第6篇，供大家参考，具体内容如下

定义一个障碍模型函数：

def things(thingx, thingy, thingw, thingh, color): pygame.draw.rect(gameDisplay, color, [thingx, thingy, thingw, thingh])

在游戏循环中调用：

things(thing_startx, thing_starty, thing_width, thing_height, black)thing_starty += thing_speed

障碍消失之后修改x值：

if thing_starty > display_height: thing_starty = 0 - thing_height thing_startx = random.randrange(0, display_width)

全部代码：

import pygameimport timeimport random pygame.init() white = (255,255,255)black = (0,0,0)gray = (128,128,128)red = (255,0,0)green = (0,255,0)blue = (0,0,255) 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 things(thingx, thingy, thingw, thingh, color): pygame.draw.rect(gameDisplay, color, [thingx, thingy, thingw, thingh])   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  thing_startx = random.randrange(0, display_width) thing_starty = -600 thing_speed = 7 thing_width = 100 thing_height = 100  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)  things(thing_startx, thing_starty, thing_width, thing_height, black) thing_starty += thing_speed  car(x,y) if x > display_width - car_width or x < 0:  gameExit = True if thing_starty > display_height:  thing_starty = 0 - thing_height  thing_startx = random.randrange(0, display_width) pygame.display.update() clock.tick(60)crash()#game_loop()pygame.quit()quit()
