C ++ 2D阵列迷宫游戏问题（坐标问题）

本文介绍了C ++ 2D阵列迷宫游戏问题（坐标问题）的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 我有这个迷宫游戏，你必须使用@符号来推o符号，它可以工作，但是对于一个小问题：当我试图移动@符号时，o符号向错误的方向移动。我想也许坐标不正确（也许dy dx不合适）但是我不确定你们能帮我解决这个问题吗？ 因为你需要查看整个代码我只会显示整个代码:(我知道代码有点长，但我找不到任何其他方式在代码中显示我的问题） b $ bI have got this maze game where you have to use the @ symbol to push the o symbols , and it works, but for one little problem : when I try to move the @ symbol then the o symbols moves in wrong strange directions. I think perhaps the coordinates are not put right ( maybe the dy dx are not put right ) but I am not sure can you guys help me out on this one ?Since you need to see the entire code I shall just show the entire code : ( I know the code is kind of long , but I cannot find any other way to show my problem in the code )-----------------------------------------------------#include <iostream> //for output and input: cout <<, cin >> #include <iomanip> //for output manipulators #include <conio.h> //for getch() #include <string> //for string using namespace std;
