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
