本人新人一枚，第一次在CSDN上写博客，代码不难，主要是混个积分。
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(x20),int(y20)]
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()
fpsColck.tick(50)
if name == ‘main‘:
main()
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]
这三段代码可以进行修改参数，修改蛇的起始坐标，长度以及目标方块坐标。
才学3个礼拜的python，写着玩一下。
