用 Python 实现植物大战僵尸代码！_python海龟编程代码大全植物大战

• plant_frozen_time_list[0] 是太阳花的冷却时间。

植物卡片类

---

每个植物卡片是一个单独的Card类，用来显示这个植物。

• checkMouseClick函数：判断鼠标是否点击到这个卡片；

• canClick：判断这个卡片是否能种植（有没有足够的点数，是否还在冷却时间内）；

• update 函数：通过设置图片的透明度来表示这个卡片是否能选择。

卡片栏类

---

MenuBar类显示图3中的植物卡片栏：

• self.sun_value：当前采集的太阳点数；

• self.card_list: 植物卡片的list；

• setupCards函数：遍历初始化__init__函数中传入这个关卡选好的植物卡片list，依次创建Card类，设置每个卡片的显示位置；

• checkCardClick函数：检查鼠标是否点击了卡片栏上的某个植物卡片，如果选择了一个可种植的卡片，返回结果。

自我介绍一下，小编13年上海交大毕业，曾经在小公司待过，也去过华为、OPPO等大厂，18年进入阿里一直到现在。

深知大多数Python工程师，想要提升技能，往往是自己摸索成长或者是报班学习，但对于培训机构动则几千的学费，着实压力不小。自己不成体系的自学效果低效又漫长，而且极易碰到天花板技术停滞不前！

因此收集整理了一份《2024年Python开发全套学习资料》，初衷也很简单，就是希望能够帮助到想自学提升又不知道该从何学起的朋友，同时减轻大家的负担。

既有适合小白学习的零基础资料，也有适合3年以上经验的小伙伴深入学习提升的进阶课程，基本涵盖了95%以上前端开发知识点，真正体系化！

由于文件比较大，这里只是将部分目录大纲截图出来，每个节点里面都包含大厂面经、学习笔记、源码讲义、实战项目、讲解视频，并且后续会持续更新

如果你觉得这些内容对你有帮助，可以扫码获取！！！（备注：Python）
