Python贪吃蛇游戏编写代码

这篇文章主要为大家详细介绍了Python贪吃蛇游戏的编写代码,文中示例代码介绍的非常详细,具有一定的参考价值,感兴趣的小伙伴们可以参考一下

最近在学Python,想做点什么来练练手,命令行的贪吃蛇一般是C的练手项目,但是一时之间找不到别的,就先做个贪吃蛇来练练简单的语法。

由于Python监听键盘很麻烦,没有C语言的kbhit(),所以这条贪吃蛇不会自己动,运行效果如下:

要求:用#表示边框,用*表示食物,o表示蛇的身体,O表示蛇头,使用wsad来移动

Python版本:3.6.1

系统环境:Win10

类:

  board:棋盘,也就是游戏区域

  snake:贪吃蛇,通过记录身体每个点来记录蛇的状态

  game:游戏类

  本来还想要个food类的,但是food只需要一个坐标,和一个新建,所以干脆使用list来保存坐标,新建food放在game里面,从逻辑上也没有太大问题

源码:

 # Write By Guobao # 2017/4//7 # # 贪吃蛇 # 用#做边界,*做食物,o做身体和头部 # python 3.6.1 import copy import random import os import msvcrt # the board class, used to put everything class board: __points =[] def __init__(self): self.__points.clear() for i in range(22): line = [] if i == 0 or i == 21: for j in range(22): line.append('#') else: line.append('#') for j in range(20): line.append(' ') line.append('#') self.__points.append(line) def getPoint(self, location): return self.__points[location[0]][location[1]] def clear(self): self.__points.clear() for i in range(22): line = [] if i == 0 or i == 21: for j in range(22): line.append('#') else: line.append('#') for j in range(20): line.append(' ') line.append('#') self.__points.append(line) def put_snake(self, snake_locations): # clear the board self.clear() # put the snake points for x in snake_locations: self.__points[x[0]][x[1]] = 'o' # the head x = snake_locations[len(snake_locations) - 1] self.__points[x[0]][x[1]] = 'O' def put_food(self, food_location): self.__points[food_location[0]][food_location[1]] = '*' def show(self): os.system("cls") for i in range(22): for j in range(22): print(self.__points[i][j], end='') print() # the snake class class snake: __points = [] def __init__(self): for i in range(1, 6): self.__points.append([1, i]) def getPoints(self): return self.__points # move to the next position # give the next head def move(self, next_head): self.__points.pop(0) self.__points.append(next_head) # eat the food # give the next head def eat(self, next_head): self.__points.append(next_head) # calc the next state # and return the direction def next_head(self, direction='default'): # need to change the value, so copy it head = copy.deepcopy(self.__points[len(self.__points) - 1]) # calc the "default" direction if direction == 'default': neck = self.__points[len(self.__points) - 2] if neck[0] > head[0]: direction = 'up' elif neck[0]  head[1]: direction = 'left' elif neck[1] = 15: self.show() print("Good Job") break else: self.new_food() self.show() # 反向一Q日神仙 elif new_head == self.snake.getPoints()[len(self.snake.getPoints()) - 2]: pass # rush the wall elif self.board.getPoint(new_head) == '#' or self.board.getPoint(new_head) == 'o': print('GG') break # normal move else: self.snake.move(new_head) self.show() op = msvcrt.getch() game().run() 

笔记:

  1.Python 没有Switch case语句,可以利用dirt来实现

  2.Python的=号是复制,复制引用,深复制需要使用copy的deepcopy()函数来实现

  3.即使在成员函数内,也需要使用self来访问成员变量,这和C++、JAVA很不一样
