本文為大家分享了pygame游戲之旅的第6篇，供大家參考，具體內容如下
定義一個障礙模型函數：
def things(thingx, thingy, thingw, thingh, color): pygame.draw.rect(gameDisplay, color, [thingx, thingy, thingw, thingh])
在游戲循環中調用：
things(thing_startx, thing_starty, thing_width, thing_height, black) thing_starty += thing_speed
障礙消失之后修改x值：
if thing_starty > display_height: thing_starty = 0 - thing_height thing_startx = random.randrange(0, display_width)
全部代碼：
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()
