?植物大戰(zhàn)僵尸的人氣可謂是經(jīng)久不衰，晃著腦袋生產(chǎn)陽光的向日葵，突突突吐著子彈的豌豆射手！?

行動遲緩種類豐富的僵尸……印象最深的是“僵尸吃掉了你的腦子！”還有瘋狂的戴夫，無一不喚醒

著我們的童年記憶?

山民們闖到哪一關(guān)了？解鎖了哪些植物？

對！沒錯，就是這個大工程今天帶大家做一款Python版本的植物大戰(zhàn)僵尸游戲！

首先準(zhǔn)備好相應(yīng)的素材如下：【超多僅展示小部分】

定義所有的植物卡片的名稱和屬性都保存在單獨(dú)的list中，每個list index都對應(yīng)一種植物，每個植物

卡片是一個單獨(dú)的Card類，用來顯示這個植物，然后每個植設(shè)置植物的卡片欄目。

植物卡片欄目截圖如下：

設(shè)置的幾種植物截圖如下：

然后使用setupMouseImage 函數(shù)實(shí)現(xiàn)鼠標(biāo)圖片切換為選中的植物。

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, 0rect = frame_list[0].get_rect()width, height = rect.w, rect.hif plant_name == c.POTATOMINE or plant_name == c.SQUASH:color = c.WHITEelse:color = c.BLACKself.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 = Trueself.plant_name = plant_nameself.plant_cost = plant_costdef removeMouseImage(self):pg.mouse.set_visible(True)self.drag_plant = Falseself.mouse_image = Noneself.hint_image = Noneself.hint_plant = False

效果圖如下：開始界面只有一個關(guān)卡，but一個關(guān)卡有不同的關(guān)。

?

?嗯哼~好啦其實(shí)后面關(guān)卡有驚喜的啦~這里就不透露了~

總結(jié)

這款植物大戰(zhàn)僵尸游戲界面還是蠻不錯的啦 還原度很高~
