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 pygame
import time
import 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 = 800
display_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()
