我半夜爬起来，用python给失眠的隔壁小姐姐：写了一个迷宫小游戏~~~

Posted 2021-05-24 L e x

大家好，我是Lex 喜欢欺负超人那个Lex

划重点：

1、python开发小游戏，pygame环境搭建；

2、给失眠的小姐姐开发一个迷宫小游戏。

代码干货满满，建议收藏+实操！！！有问题及需要，请留言哦~~

事情是这样的

半夜听到隔壁来来回回 ，忙忙碌碌的声音

我这么心思细腻 体贴入微的python小哥哥

敏锐的感觉到

小姐姐肯定是失眠了

好担心哦，我都睡不着了呢

辗转反侧

最后爬起来撸出了我的python代码

 

一、环境要求

windows系统，python3.6+

安装游戏依赖模块

pip install pyqt5

pip install pygame

二、游戏介绍

1、游戏目标

随机生成一张迷宫地图，将玩家设置在迷宫内部，通过光标 上 下 左 右，来移动玩家，按照迷宫地图的道路来走出迷宫。

 

2、先上游戏效果图

 

三、完整开发流程

1、项目主结构

首先，先整理一下项目的主结构，其实看一下主结构，基本就清晰了

modules：存放自己写的python类
——mazes.py
——misc.py
——sprites.py

resources：存放引用到的图片、音频等等
——audios:音频资源
——images:图片资源

config.py：为主配置文件

maze.py：主程序文件

requirements.txt：需要引入的python依赖包

 

2、详细配置

config.py

配置文件中，需要引入os模块，并且配置打开游戏的屏幕大小，并将资源中引用到的图片、音频插入到合适的位置。

因为我们的迷宫游戏，需要划开模块。

'''配置文件'''
import os


'''屏幕大小'''
SCREENSIZE = (800, 625)
'''游戏素材'''
BGMPATH = os.path.join(os.getcwd(), 'resources/audios/bgm.mp3')
HEROPICPATH = os.path.join(os.getcwd(), 'resources/images/hero.png')
'''FPS'''
FPS = 20
'''块大小'''
BLOCKSIZE = 15
MAZESIZE = (35, 50) # num_rows * num_cols
BORDERSIZE = (25, 50) # 25 * 2 + 50 * 15 = 800, 50 * 2 + 35 * 15 = 625

 

3、随机生成迷宫地图

mazes.py

迷宫虽然是个小游戏，但是我们每次打开，进入 地图需要随机生成一个新地图。

定义randommaze 随机生成地图，并将地图投在主游戏屏幕上

        Interface(screen, config, mode='game_switch')


'''run'''
if __name__ == '__main__':
    main(config)

四、游戏启动方法

1、开发工具启动

如果你配置了开发工具的环境VScode、sublimeText、notepad+、pycharm什么的，可以直接在工具中，运行游戏。

如果没配置，可以使用命令启动。

2、命令行启动 gif
