今天，给大家介绍一个简单易懂的贪吃蛇小游戏

代码 如下

import pygame,sys,random
from pygame.locals import *
#定义颜色变量 目标方块的颜色
redColor = pygame.Color(250,0,0)
#贪吃蛇的颜色
whiteColor = pygame.Color(255,255,255)
#背景颜色
blackColor = pygame.Color(0,0,0)

def gameOver():
pygame.quit()
sys.exit()

def main():
#初始化pygame
pygame.init()
#控制游戏速度
fpsColck = pygame.time.Clock()
#创建pygame显示层
playSurface = pygame.display.set_mode((640,480))
pygame.display.set_caption(\'贪吃蛇\')
#初始化贪吃蛇的起始坐标
snakePosition = [100,100]
#初始化贪吃蛇的长度
snakeBody = [[100,100],[80,100],[60,100]]
#初始化目标方块的坐标
targetPosition = [300,300]
#初始化一个目标方块的标记 目的：用来判断是否吃掉这个目标方块
targerflag = 1
#初始化方向
direction = \'right\'
#定义一个方向变量
changeDirection = direction

while True:
for event in pygame.event.get():

if event.type == QUIT:
pygame.quit()
sys.exit()
elif event.type == KEYDOWN:
if event.key == K_RIGHT:
changeDirection = \'right\'
if event.key == K_LEFT:
changeDirection = \'left\'
if event.key == K_UP:
changeDirection = \'up\'
if event.key == K_DOWN:
changeDirection = \'down\'
#对应键盘Esc键
if event.key == K_ESCAPE:
pygame.event.post(pygame.event.Event(QUIT))
#确定方向
if changeDirection == \'left\' and not direction == \'right\':
direction = changeDirection
if changeDirection == \'right\' and not direction == \'left\':
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\':
snakePosition[0] += 20
if direction == \'left\':
snakePosition[0] -= 20
if direction == \'up\':
snakePosition[1] -= 20
if direction == \'down\':
snakePosition[1] += 20

#增加蛇的长度
snakeBody.insert(0,list(snakePosition))

#判断目标方块是否被吃掉
if snakePosition[0] == targetPosition[0] and snakePosition[1] == targetPosition[1]:
targerflag = 0
else:
snakeBody.pop()

if targerflag == 0:
x = random.randrange(1,32)
y = random.randrange(1,24)
targetPosition = [int(x*20),int(y*20)]
targerflag = 1
#绘制pygame的显示层
playSurface.fill(blackColor)

for position in snakeBody:
pygame.draw.rect(playSurface,whiteColor,Rect(position[0],position[1],20,20))
pygame.draw.rect(playSurface,redColor,Rect(targetPosition[0],targetPosition[1],20,20))

pygame.display.flip()

if snakePosition[0]> 620 or snakePosition[0] < 0:
gameOver()
elif snakePosition[1] > 460 or snakePosition[1] < 0:
gameOver()
#修改速度
fpsColck.tick(10)

if __name__ == \'__main__\':
main()
