一:实验需求
实验环境:python3.8,pycharm
需要的库:pygame,random
需要下载64位对应python37版本的pygame网址
https://pypi.org/project/Pygame/1.9.4/#files
这里贴个安装方法。

二:实验思路
这里介绍下贪吃蛇原理和pygame常用方法
pygame三大对象
pygame.display 显示
pygame.time 时间
pygame.event 事件
pygame.draw 绘制
颜色——RGB
red=(255,0,0)
white=(255,255,255)
black=(0,0,0)
#格子
0 0 0 0 3 0 0
0 0 0 1 2 3 0
0 0 0 0 0 0 0
0 0 0 0 0 0 0
#画出来–核心
left=c *width
top=r * height
#移动
向左
row
col-=1
向右
col+=1
#正常移动
1.把原来的头插到前面
2.把原来的尾巴删掉
#蛇身
head=(14,7)
l=[
(14,8)
(14,9)
(14,10)
(14,11)
(14,12)
(14,13)
(14,14)
]
head=(14,6)
l=[
(14,7)#原来的位置
(14,8)
(14,9)
(14,10)
(14,11)
(14,12)
(14,13)
(14,14)#原来的尾巴
]
#食物随机位置
三:源码
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)
#初始框架
import pygame
import random
#初始化
pygame.init()
W=800
H=600
ROW=30
COL=40
size=(W,H)
window=pygame.display.set_mode(size)
pygame.display.set_caption('贪吃蛇')
bg_color=(255,255,255)
snake_color=(200,200,200)
head=Point(row=int(ROW/2), col=int(COL/2))
head_color=(0,128,128)
snakes=[
Point(row=head.row, col=head.col+1),
Point(row=head.row, col=head.col+2),
Point(row=head.row, col=head.col+3)
]
#生成食物
def gen_food():
while 1:
pos=Point(row=random.randint(0,ROW-1), col=random.randint(0,COL-1))
#
is_coll=False
#是否跟蛇碰上了
if head.row==pos.row and head.col==pos.col:
is_coll=True
#蛇身子
for snake in snakes:
if snake.row==pos.row and snake.col==pos.col:
is_coll=True
break
if not is_coll:
break
return pos
#定义坐标
food=gen_food()
food_color=(255,255,0)
direct='left' #left,right,up,down
#
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:
#处理事件
for event in pygame.event.get():
if event.type==pygame.QUIT:
quit=False
elif event.type==pygame.KEYDOWN:
if event.key==273 or event.key==119:
if direct=='left' or direct=='right':
direct='up'
elif event.key==274 or event.key==115:
if direct == 'left' or direct == 'right':
direct='down'
elif event.key==276 or event.key==97:
if direct == 'up' or direct == 'down':
direct='left'
elif event.key==275 or event.key==100:
if direct == 'up' or direct == 'down':
direct='right'
#吃东西
eat=(head.row==food.row and head.col==food.col)
#重新产生食物
if eat:
food = gen_food()
#处理身子
#1.把原来的头,插入到snakes的头上
snakes.insert(0, head.copy())
#2.把snakes的最后一个删掉
if not eat:
snakes.pop()
#移动
if direct=='left':
head.col-=1
elif direct=='right':
head.col+=1
elif direct=='up':
head.row-=1
elif direct=='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 snakes:
if head.col==snake.col and head.row==snake.row:
dead=True
break
if dead:
print('死了')
quit=False
#渲染——画出来
#背景
pygame.draw.rect(window, bg_color, (0,0,W,H))
#蛇头
for snake in snakes:
rect(snake, snake_color)
rect(head, head_color)
rect(food, food_color)
#
pygame.display.flip()
#设置帧频
clock.tick(20)
#收尾工作
完成啦!在贴一个我的源码和笔记供大家参考。
