使用Python第三方库pygame写个贪吃蛇小游戏

今天看到几个关于pygame模块的博客和视频，感觉非常有趣，这里照猫画虎写了一个贪吃蛇小游戏，目前还有待完善，但是基本游戏功能已经实现，下面是代码：

# 导入模块
import pygame
import random
# 初始化
pygame.init()
w = 720   #窗口宽度
h = 600   #窗口高度
ROW = 30  #行数
COL = 36  #列数
#将所有的坐标看作是一个个点，定义点类
class Point:  
 row = 0
 col = 0
 def __init__(self, row, col):
   self.row = row
   self.col = col
 def copy(self):
   return Point(row = self.row,col = self.col)
#显示窗口和标题
size = (w, h)
window = pygame.display.set_mode(size)
pygame.display.set_caption('贪吃蛇')
#定义蛇头坐标
head = Point(row = ROW/2, col = COL/2)
#蛇身体
snake_list = [
 Point(row = head.row,col = head.col+1),
 Point(row = head.row,col = head.col+2),
 Point(row = head.row,col = head.col+3)
]
#产生食物
def pro_food():
 #食物不能与蛇重叠
 while True:
   pos = Point(row=random.randint(1,ROW-2), col=random.randint(1,COL-2))
   is_coll = False
   if head.row == pos.row and head.col == pos.col:
     is_coll = True
   for snake in snake_list:
     if snake.col == pos.col and snake.row == pos.row:
       is_coll = True
       break
   if not is_coll:
     return pos
food = pro_food()
#定义颜色
bg_color = (255, 255, 255)
head_color = (0, 128, 128)
food_color = (255, 255, 0)
snake_color = (200,200,200)
#给定初始方向
dire = 'left'
def rect(point, color):
 cell_width = w/COL
 cell_height = h/ROW
 left = point.col*cell_width
 top = point.row*cell_height
 pygame.draw.rect(
   window, color,
   (left,top,cell_width, cell_height, )
 )
 pass
# 游戏循环
quit = True
clock = pygame.time.Clock()
while quit:
 for event in pygame.event.get():
   #退出方式
   if event.type == pygame.QUIT:
     quit = False
   elif event.type == pygame.KEYDOWN:
     #键盘控制
     if event.key == 273 or event.key == 119:
       if dire == 'left' or dire == 'right':
         dire = 'up'
     elif event.key == 274 or event.key == 115:
       if dire == 'left' or dire == 'right':
         dire = 'down'
     elif event.key == 276 or event.key == 97:
       if dire == 'up' or dire == 'down':
         dire = 'left'
     elif event.key == 275 or event.key == 100:
       if dire == 'up' or dire == 'down':
         dire = 'right'
 #吃
 eat=(head.row == food.row and head.col == food.col)
 if eat:
   food = pro_food()
 #处理身体
 #1.原来的头换到身体最前端
 snake_list.insert(0,head.copy())
 #2.删除身体最后一个
 if not eat:
   snake_list.pop()
 #移动
 if dire == 'left':
   head.col -= 1
 elif dire == 'right':
   head.col += 1
 elif dire == 'up':
   head.row -= 1
 elif dire == 'down':
   head.row += 1
 #检测：
 dead=False
 #1.撞墙
 if head.col < 0 or head.row< 0 or head.col >= COL or head.row >= ROW:
   dead=True
 #2.撞自己
 for snake in snake_list:
   if head.col == snake.col and head.row == snake.row:
     dead=True
     break
 if dead:
   print('dead')
   quit = False
 #绘制背景
 pygame.draw.rect(window, bg_color, (0, 0, w, h))
 #蛇头
 rect(head, head_color)
 #食物
 rect(food,food_color)
 #蛇身
 for snake in snake_list:
   rect(snake,snake_color)
 pygame.display.flip()
 #游戏帧数
 clock.tick(20)

效果：
