小时候玩的“坦克大战”，你还记得吗？
满满的回忆
！
今天，我们使用Python以及强大的第三方库来实现一个简单的坦克大战游戏。
整体效果
环境依赖
python3.7
pygame1.9.6
urllib
内置库，如random、sys、time、os等
pygame介绍
Pygame被设计用来写游戏的python模块集合，基于SDL库开发。使用python可以导入pygame来开发具有全部特性的游戏和多媒体软件，Pygame是极度轻便的并且可以运行在几乎所有的平台和操作系统上。
1. 导入依赖 & 通用配置
1importrandom
2importsys
3importtime
4fromurllib.requestimporturlretrieve
5importos
6importpygame
7
8
9SCREEN_WIDTH, SCREEN_HEIGHT =1200,700# 画面大小
10MY_BIRTH_LEFT, MY_BIRTH_TOP = SCREEN_WIDTH /2, SCREEN_HEIGHT -60
11DIRECTION = [U, D, L, R] = [ U , D , L , R ]# 控制键
12Tank_IMAGE_POSITION =r D:/tank_img
13URL = https://gitee.com/tyoui/logo/raw/master/img/
2. 通用加载函数
1# 加载图片
2defload_img(name_img):
3save = Tank_IMAGE_POSITION + os.sep + name_img + .gif
4ifnotos.path.exists(save):
5urlretrieve(URL + name_img + .gif , save)
6returnpygame.image.load(save)
7
8# 加载背景音乐
9defload_music(name_music):
10save = Tank_IMAGE_POSITION + os.sep + name_music + .wav
11ifnotos.path.exists(save):
12urlretrieve(URL + name_music + .wav , save)
13pygame.mixer.music.load(save)
14pygame.mixer.music.play()
3. 通用基础类
1
2* pygame.sprite模块，官方文档上说这个模块是轻量级的，在游戏开发中也未必要使用。
3* sprite翻译为精灵，在游戏动画一般是指一个独立运动的画面元素，在pygame中，
4就可以是一个带有图像（Surface）和大小位置（Rect）的对象。
5* pygame.sprite.Sprite是pygame精灵的基类，一般来说，需要写一个自己的精灵类继承一下它然后加入自己的代码。
