小時候玩的“坦克大戰(zhàn)”，你還記得嗎？
滿滿的回憶
！
今天，我們使用Python以及強大的第三方庫來實現(xiàn)一個簡單的坦克大戰(zhàn)游戲。
整體效果
環(huán)境依賴
python3.7
pygame1.9.6
urllib
內置庫，如random、sys、time、os等
pygame介紹
Pygame被設計用來寫游戲的python模塊集合，基于SDL庫開發(fā)。使用python可以導入pygame來開發(fā)具有全部特性的游戲和多媒體軟件，Pygame是極度輕便的并且可以運行在幾乎所有的平臺和操作系統(tǒng)上。
1. 導入依賴 & 通用配置

9SCREEN_WIDTH,?SCREEN_HEIGHT?=1200,700#?畫面大小
10MY_BIRTH_LEFT,?MY_BIRTH_TOP?=?SCREEN_WIDTH?/2,?SCREEN_HEIGHT?-60
11DIRECTION?=?[U,?D,?L,?R]?=?[ U , D , L , R ]#?控制鍵
12Tank_IMAGE_POSITION?=r D:/tank_img
13URL?= https://gitee.com/tyoui/logo/raw/master/img/
?2. 通用加載函數(shù)
1#?加載圖片
2defload_img(name_img):

4ifnotos.path.exists(save):
5urlretrieve(URL?+?name_img?+ .gif ,?save)

11ifnotos.path.exists(save):
12urlretrieve(URL?+?name_music?+ .wav ,?save)
13pygame.mixer.music.load(save)
14pygame.mixer.music.play()
3. 通用基礎類
1
2* pygame.sprite模塊，官方文檔上說這個模塊是輕量級的，在游戲開發(fā)中也未必要使用。
3*?sprite翻譯為精靈，在游戲動畫一般是指一個獨立運動的畫面元素，在pygame中，
4就可以是一個帶有圖像（Surface）和大小位置（Rect）的對象。
5* pygame.sprite.Sprite是pygame精靈的基類，一般來說，需要寫一個自己的精靈類繼承一下它然后加入自己的代碼。
