写在前面：

今天给大家推荐一个Gtihub开源项目：PythonPlantsVsZombies，翻译成中就是植物大战僵尸。

《植物大战僵尸》是一款极富策略性的小游戏。可怕的僵尸即将入侵，每种僵尸都有不同的特点，例如铁桶僵尸拥有极强的抗击打能力，矿工僵尸可以挖地道绕过种植在土壤表面的植物等。玩家防御僵尸的方式就是栽种植物。49种植物每种都有不同的功能，例如樱桃炸弹可以和周围一定范围内的所有僵尸同归于尽，而食人花可以吃掉最靠近自己的一只僵尸。玩家可以针对不同僵尸的弱点来合理地种植植物，这也是胜利的诀窍。游戏根据玩法不同分为五种游戏模式：冒险模式、迷你模式、解谜模式、生存模式、禅境花园。加之黑夜、屋顶、浓雾以及泳池之类的障碍增加了其挑战性。该游戏近乎永无止境。

功能实现

• 支持的植物：向日葵、豌豆射手、胡桃、雪豌豆射手、樱桃炸弹、三豌豆射手、大嘴花、puffshroom、马铃薯胺、穗状杂草、南瓜、胆小菇、墨西哥胡椒、阳光菇、冰川菇、催眠蘑菇。

• 支持僵尸：普通僵尸，旗帜僵尸，路障僵尸，铁桶僵尸，报纸僵尸。

• 支持在关卡开始时选择植物卡片。

• 支持白天级别、夜间级别、移动卡选择级别和胡桃保龄球级别。

环境要求

• 1、python3.7
  注意： Python3.7是最佳运行环境，但是不是强制性要求。对于Linux： 如果你的 Linux 有预装的 Python3+ 就可以运行了。LINUX Mint 操作系统直接升级到 Python 3.7 有可能导致系统自带的 python 版本无法执行。

• 2、Python-Pygame 1.9

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
5级：墙果保龄球级别

个性化定义

游戏的关卡数据，存储在json文件里的。具体目录：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。
