学习c++有一段时间了，之前在慕课网碰到的一道题，老师给的，这里写图片描述大致说下吧，P代表人，开始时P在起点，然后P根据地图(‘#’代表墙，空格代表路）来判断前进的方向，并且为了实现动画效果，可以用这样一个函数

void Person::goto_Pos(Coor c){ COORD cd; cd.X = c.y+1; cd.Y = c.x; SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), cd);}

该函数可以将光标定位到坐标(cx.X,cx.Y)位置，光标的位置坐标是这样的：x从左到右增加，y从上到下增加这里写图片描述而地图是用字符数组画出来的，所以地图的坐标是这样的：所以要想将光标定位到地图的(x,y)处，就是将光标移动到(y,x)处；还有一点要注意的是，为了实现动画效果，先将光标定位到先前位置，擦除该字符，然后将光标定位到当前位置，擦除此处的字符(墙或者路),再输出人的字符(‘P’)，所以用的是’/b’,所以应该将光标定位到地图坐标再往右移动一位，先做个小例子熟悉一下这个函数的用法吧

# include<iostream># include<string># include<windows.h>using namespace std;void gotoxy(int x, int y){ COORD cd; cd.X = x; cd.Y = y; SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), cd); Sleep(1000);}int main(){ cout << "1,2,3,4,5,6,7,8,9"; for (int i = 1;i <= 9;i++) { gotoxy(2*i-1, 0); cout << '/b' << 2 * i; } gotoxy(0, 5); system("pause"); return 0;}

好了，以下是自己做的迷宫游戏源码
