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 pgfrom source.main import mainif __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。
