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......_python植物大战僵尸游戏图片

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。

植物卡片栏目截图如下：

设置的几种植物截图如下：

然后使用setupMouseImage 函数实现鼠标图片切换为选中的植物。

    def setupMouseImage(self, plant_name, plant_cost):
        frame_list = tool.GFX[plant_name]
        if plant_name in tool.PLANT_RECT:
            data = tool.PLANT_RECT[plant_name]
            x, y, width, height = data['x'], data['y'], data['width'], data['height']
        else:
            x, y = 0, 0
            rect = frame_list[0].get_rect()
            width, height = rect.w, rect.h
 
        if plant_name == c.POTATOMINE or plant_name == c.SQUASH:
            color = c.WHITE
        else:
            color = c.BLACK
        self.mouse_image = tool.get_image(frame_list[0], x, y, width, height, color, 1)
        self.mouse_rect = self.mouse_image.get_rect()
        pg.mouse.set_visible(False)
        self.drag_plant = True
        self.plant_name = plant_name
        self.plant_cost = plant_cost
 
    def removeMouseImage(self):
        pg.mouse.set_visible(True)
        self.drag_plant = False
        self.mouse_image = None
        self.hint_image = None
        self.hint_plant = False

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~
