Python植物大战僵尸源码分享

前言

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。

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

环境要求

1、python3.7

2、Python-Pygame 1.9
