植物大战僵尸Python版，附带源码注解 在PythonPlantsVsZombies-master\source\data，我们可以进行自定义配置，例如僵尸的位置和时间，背景信息。

目录

一、实现功能

二、安装环境要求

三、如何开始游戏

四、怎么玩

五、演示

六、部分源码注释

6.1main.py

6.2map.py

6.3Menubar.py

七、自定义

7.1plant.json

7.2zombie.json

一、实现功能

• 实施植物：向日葵、豌豆射手、壁桃、雪豆射手、樱桃炸弹、三豌豆射手、大口蘑菇，海扁蘑菇，土豆，尖刺草，惊吓蘑菇，南瓜，惊吓蘑菇，墨西哥辣椒，太阳蘑菇，冰蘑菇，催眠蘑菇。
• 实现僵尸：僵尸、旗帜僵尸、锥头僵尸、桶头僵尸、报纸僵尸。
• 使用JSON文件存储关卡数据（例如僵尸的位置和时间，背景信息）
• 支持在关卡开始时选择植物卡
• 支持日间关卡、夜间关卡、移动卡选择关卡和壁桃保龄球关卡

二、安装环境要求

• Python 3.7
• Notice:建议使用 python 3.7 版本，但不是必需的。对于 LINUX：如果您的 Linux 系统预装了 python 3+，则可以运行此游戏。直接更新到 python 3.7 可能会破坏 LINUX Mint。
• Python-Pygame 1.9

三、如何开始游戏

python main.py

四、怎么玩

• 使用鼠标收集阳光，选择植物卡片并播种植物
• 您可以通过更改 source/constants.py 中的START_LEVEL_NUM值来设置起始级别
  • 级别 1 和 2：天级别
  • 第 3 级：夜间级别
  • 第 4 级：移动卡片选择级别
  • 第5级：墙果保龄球级别

五、演示

六、部分源码注释

项目结构如下：

6.1main.py

import pygame as pg
from source.main import main
if __name__=='__main__':
 main()
 pg.quit()

6.2map.py

   定义了一个地图类 Map，包含了地图的初始化、位置验证、可移动性检查、位置转换等方法。
