Pygame实战：据说—这是一款还原度超高的植物大战僵尸游戏，你感受下......
导语
哈喽！大家好，我是木木子！
又到了每日游戏更新系列，看到这么如下.gif是不是让你想起来了童年吖~
植物大战僵尸的人气可谓是经久不衰，晃着脑袋生产阳光的向日葵，突突突吐着子弹的豌豆射手！
行动迟缓种类丰富的僵尸……印象最深的是“僵尸吃掉了你的脑子！”还有疯狂的戴夫，无一不唤醒着我们的童年记忆
山民们闯到哪一关了？解锁了哪些植物？
对！没错，就是这个大工程今天带大家做一款Python版本的植物大战僵尸游戏！

首先准备好相应的素材如下：【超多仅展示小部分】
定义所有的植物卡片的名称和属性都保存在单独的list中，每个list index都对应一种植物，每个植物卡片是一个单独的Card类，用来显示这个植物，然后每个植设置植物的卡片栏目。

效果图如下：开始界面只有一个关卡，but一个关卡有不同的关。
嗯哼~好啦其实后面关卡有惊喜的啦~这里就不透露了~
总结
这款植物大战僵尸游戏界面还是蛮不错的啦 还原度很高~
