讯飞星火胜出！
只有讯飞星火未做任何修改，代码直接拿来就能运行，胜出！
但只说明仅此一个问题的胜出，并非就说讯飞整体就比其它两家强哦！
代码改进
简单做了2个小的优化改进：
1. 代码细分为多个函数 init() repaint() quit_game() ......
2. 游戏界面增加了方格线，使用pygame.draw.lines()，快速布点是关键：
# 定义线段端点坐标时，根据规律分别写x,y坐标的数据列表
x,y = (-1,640,640,-1)*16, []
for i in range(36):
for _ in range(2):
y.append(19+i*20)
# zip()整合x,y为坐标Pair
points = list(zip(x,y))
完成代码
import pygame
import sys
import random
# 定义颜色
WHITE = (255, 255, 255)
GREEN = (0, 255, 0)
RED = (255, 0, 0)
GREY = (211, 211, 211) # 淡灰色
def init():
global screen, screen_size
global snake_pos, food_pos, snake_speed
# 初始化pygame
pygame.init()
# 设置屏幕大小
screen_size = (640, 480)
screen = pygame.display.set_mode(screen_size)
# 设置游戏标题
pygame.display.set_caption("贪吃蛇")
# 蛇的初始位置
snake_pos = [[100, 100], [80, 100], [60, 100]]
# 食物的初始位置
food_pos = [300, 300]
# 蛇的初始速度
snake_speed = [20, 0]
def repaint():
# 绘制游戏界面
screen.fill(WHITE)
# 定义线段的端点坐标
x,y = (-1,640,640,-1)*16, []
for i in range(36):
for _ in range(2):
y.append(19+i*20)
# 使用pygame.draw.lines()函数绘制线段
points = list(zip(x,y))
pygame.draw.lines(screen, GREY, False, points, 1) # 线宽为1
points = list(zip(y,x))
pygame.draw.lines(screen, GREY, False, points, 1)
# 重画蛇和食物
for pos in snake_pos:
pygame.draw.rect(screen, GREEN, pygame.Rect(pos[0], pos[1], 20, 20))
pygame.draw.rect(screen, RED, pygame.Rect(food_pos[0], food_pos[1], 20, 20))
pygame.display.flip()
def game_quit():
pygame.quit()
sys.exit()
def main():
global screen, screen_size
global snake_pos, food_pos, snake_speed
# 主循环
while True:
# 处理游戏事件
for event in pygame.event.get():
if event.type == pygame.QUIT:
game_quit()
elif event.type == pygame.KEYDOWN:
if event.key == pygame.K_UP:
snake_speed = [0, -20]
elif event.key == pygame.K_DOWN:
snake_speed = [0, 20]
elif event.key == pygame.K_LEFT:
snake_speed = [-20, 0]
elif event.key == pygame.K_RIGHT:
snake_speed = [20, 0]
# 更新蛇的位置
snake_pos.insert(0, [snake_pos[0][0] + snake_speed[0], snake_pos[0][1] + snake_speed[1]])
# 检查蛇头是否碰到食物
if snake_pos[0] == food_pos:
food_pos = [random.randrange(1, screen_size[0] // 20) * 20, random.randrange(1, screen_size[1] // 20) * 20]
else:
snake_pos.pop()
# 检查蛇头是否碰到墙壁或者蛇身
if snake_pos[0][0] < 0 or snake_pos[0][0] >= screen_size[0] or snake_pos[0][1] < 0 or snake_pos[0][1] >= screen_size[1] or snake_pos[0] in snake_pos[1:]:
game_quit()
'''
此处可增加与用户的交互，如：
if askyesno('title','again?'):
init() # Yes to Play again
else:
game_quit() # No to Exit
'''
# 重画界面及蛇和食物
repaint()
# 控制游戏速度
pygame.time.Clock().tick(10)
if __name__ == "__main__":
init()
main()
更多改进思路：
增加游戏的生命值，比如初始有3条蛇，死完后提示用户“重来”还是“退出游戏”；
增加游戏的得分，比如每吃到一个食物，得分增加10分；结束时写入排行榜；
增加游戏背景音乐和声效，提高游戏可玩性……
