一、导入pygame包，定义颜色变量（小方块的颜色和最后得分显示的结果颜色）
import pygame, sys, time, random
from pygame.locals import *
# 定义颜色变量
redColour = pygame.Color(255, 150, 150) # 控制小方块的颜色
blackColour = pygame.Color(0, 100, 150)
whiteColour = pygame.Color(255, 255, 255)
# 控制最后得分显示的结果颜色
greyColour = pygame.Color(250, 150, 150)
二、编写gameover函数，显示游戏结束界面
def gameOver(playSurface, score):
# 显示GAME OVER并定义字体以及大小
gameOver1 = pygame.font.SysFont('arial.ttf', 80)
gameOver2 = gameOver1.render('defeat!', True, greyColour) # 死亡后最上面的显示
gameOver3 = gameOver2.get_rect() # get_rect是一个处理矩形图像的方法，返回值包含矩形的居中属性
gameOver3.midtop = (300, 100)
playSurface.blit(gameOver2, gameOver3)
# 显示分数并定义字体和大小
score4 = pygame.font.SysFont('arial.ttf', 50)
score5 = score4.render("score:" + str(score), True, greyColour)
scoreRect = score5.get_rect()
scoreRect.midtop = (300, 50)
playSurface.blit(score5, scoreRect) # blit实现动画效果
pygame.display.flip()#刷新界面
time.sleep(5) # 暂停后实现
pygame.quit() # 退出pygame
sys.exit(0)#tuichu
三、编写main（）主函数，包含界面大小，游戏角标，游戏声音，以及控制游戏速度。
def main():
# 初始化pygame
pygame.init()
pygame.mixer.init()
fpsClock = pygame.time.Clock() # 多大的针
# 创建pygame显示层
jm = pygame.display.set_mode((1000, 500)) # 界面大小
# a=pygame.mixer.music.load(os.path.join(s, 'music.ogg'))
pygame.display.set_caption('贪吃蛇小游戏')
image = pygame.image.load('12345.jpg')
pygame.display.set_icon(image)
pygame.mixer.music.load('13505.wav')
# 初始化变量
snaket = [100, 100] # 贪吃蛇 蛇头的位置
snakess = [[100, 100]] # 贪吃蛇 蛇的身体，初始为一个单位
fangkuai = [100, 300] # 方块的初始位置
num = 1 # 个数为1
direction = 'down' # 初始方向为右
changeDirection = direction
score = 0 # 初始得分
while True:
# 检测例如按键等pygame事件
for event in pygame.event.get():
if event.type == QUIT:
pygame.quit()
sys.exit()
elif event.type == KEYDOWN:
# 判断键盘事件
if event.key == K_RIGHT or event.key == ord('d'):
changeDirection = 'right'
if event.key == K_LEFT or event.key == ord('a'):
changeDirection = 'left'
if event.key == K_UP or event.key == ord('w'):
changeDirection = 'up'
if event.key == K_DOWN or event.key == ord('s'):
changeDirection = 'down'
if event.key == K_ESCAPE: # esc
pygame.event.post(pygame.event.Event(QUIT)) # 单机窗口退出
# 判断是否输入了反方向
if changeDirection == 'right' and not direction == 'left':
direction = changeDirection
if changeDirection == 'left' and not direction == 'right':
direction = changeDirection
if changeDirection == 'up' and not direction == 'down':
direction = changeDirection
if changeDirection == 'down' and not direction == 'up':
direction = changeDirection
# 根据方向移动蛇头的坐标
if direction == 'right':
snaket[0] += 20
if direction == 'left':
snaket[0] -= 20
if direction == 'up':
snaket[1] -= 20
if direction == 'down':
snaket[1] += 20
# 将蛇头的位置加入列表之中
snakess.insert(0, list(snaket))
# 判断是否吃掉了方块
if snaket[0] == fangkuai[0] and snaket[1] == fangkuai[1]:
num = 0
pygame.mixer.music.play()
else:
snakess.pop()
# 如果吃掉方块，则重新生成方块
if num == 0:
x = random.randrange(1, 30)
y = random.randrange(1, 23)
fangkuai = [int(x * 20), int(y * 20)]
num = 1#没有这条代码会出现错乱
score += 1
# 绘制pygame显示层
jm.fill(whiteColour)
for i in snakess:
pygame.draw.rect(jm, blackColour, Rect(i[0], i[1], 20, 20))
pygame.draw.rect(jm, redColour, Rect(fangkuai[0], fangkuai[1], 20, 20))#方块颜色
pygame.display.flip()
# 判断是否死亡
if snaket[0] > 1000 or snaket[0] < 0:
gameOver(jm, score)
if snaket[1] > 500 or snaket[1] < 0:
gameOver(jm, score)
for i in snakess[1:]: # 蛇碰到自己
if snaket[0] == i[0] and snaket[1] == i[1]:
gameOver(jm, score)
# 控制游戏速度，蛇越长越快
if len(snakess) < 40:
sudu = 6 + len(snakess)
else:
sudu = 16
fpsClock.tick(sudu)
main()
四、完整代码展示
