Python-基于Pygame的小游戏(坦克大战-1.0(世界))（一）

前言:创作背景-《坦克大战》是一款经典的平面射击游戏，最初由日本游戏公司南梦宫于1985年在任天堂FC平台上推出。游戏的主题围绕坦克战斗，玩家的任务是保卫自己的基地，同时摧毁所有敌人的坦克。游戏中有多种地形和敌人类型，玩家可以通过获取道具来强化坦克和基地。此外，游戏还支持玩家自创关卡，增加了游戏的趣味性。游戏中，玩家通过键盘控制坦克的移动和射击，需要灵活应对敌人的攻击并操作自身坦克摧毁敌方坦克，以获得胜利。那么话不多说，本次编程我们就一起来重温这部童年经典游戏。

编程思路:本次编程我们将会用到pygame，random等库。

第一步：准备第三方库

pygame是Python的一个第三方库，它需要我们自行下载。

下载方法:在PyCharm终端中输入"pip install pygame",回车等待一段时间。

pip install pygame

第二步:准备游戏相关图片(包括敌我双方的坦克主体和炮管)

                                                               敌方坦克主体图片

敌方坦克炮管图片

我方坦克主体图片

                                                                     

                                                                我方坦克炮管图片

(需要的也可以私信我发哦)

接下来我们将图片放在python项目下。（如下红色圆圈标注所示）
