C++ EGE 实现坦克大战小游戏
因为有过一次用EGE写小游戏的经验，所以这一次写坦克大战快了很多。并且使用对象编程也简化了很多编程时繁琐的步骤。
写出坦克大战使我在学习编程的道路上又迈出了一大步。
如果您需要图片素材的，我可以单独发给您。
技术环节：
编译环境：Windows VS2019
需求：
控制坦克移动发射炮弹，炮弹可以消灭敌军坦克，且可以消灭砖块。坦克遇到方块会被挡住。敌军消灭我军三次或基地被毁则游戏失败，共摧毁十次敌方坦克游戏胜利。
思路：
先写出坦克的父类，我方坦克类和敌方坦克类继承坦克父类，实例化我方坦克和敌方坦克。地图使用list容器存储。
在代码注释中标注了每一步是怎么实现的。
注意：
因为我在程序中用了一些不规范的写法，所以要在VS中正常编译运行，需要右键源文件->属性->C/C+±>符合模式，改为否。
包含<graphics.h>图形库需要提前配置EGE图形库。
如要在其他graphics图形库下编译，可能需要修改某些地方。
运行效果：
#include <graphics.h> //图形库
#include <ctime> //time();
#include <list> //list容器
using namespace std; //标准命名空间 list等
//设置图片对象中图片的宽高 全局函数
//参数：宽、高、对象名
void setimage(int pwidth, int pheight, PIMAGE img_1);
//地图全局结构
struct mapstr
{
int m_x; //xy坐标
int m_y;
int prop; //属性
};
//地图类
class Mymap
{
private:
list<mapstr> listmap; //地图容器，存储全地图信息，全地图1350个20*20的格子
public:
//设置地图
Mymap()
{
mapstr temp;
//构造函数为链表容器中的地图赋值
//全地图横向45个格子 竖向30个格子
//基地部分

getimage(img_1, img_2, 0, 0, pwidth, pheight); //img再获取img_2中的图像
delimage(img_2); //使用完毕将释放掉
}
不足之处：
参照标准的坦克大战，子弹在攻击砖块时，如果子弹正好打中两个砖块，则两个砖块同时被消灭，这个效果我在程序中做不出来。只能是用一个一个地消灭代替了。
在按下键键值不是wasdj时和坦克碰到墙壁时坦克会闪的问题，也暂时没有找到解决办法。
因为初学C++，所以我在类和对象的使用上面还有着很多很多的缺陷和不规范的地方。
还有关于地图的问题，因为我没有经验，所以不知道该怎么简便地创造一个游戏地图，在刚开始的时候还在为用什么实现地图而犹豫过，最后还是选择了list容器逐个将地图元素塞进去，因为考虑到list容器插入和删除数据很快。
我知道在程序中很多地方我都写的极为地不合理，以至于程序运行效率非常低（从我的CPU占用看出来的），但是我会继续努力，继续学习，争取早日解决这些问题。
欢迎大家提出批评和建议。
感谢大家的支持。
