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！
正文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。

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 = https://www.it610.com/article/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.hif 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_costdef removeMouseImage(self): pg.mouse.set_visible(True) self.drag_plant = False self.mouse_image = None self.hint_image = None self.hint_plant = False
