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
