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：
