抱歉，标题令人迷惑，我在C ++方面还很陌生，正在尝试在命令行中制作迷宫游戏。它通常可以正常工作，但是每当我移动角色（或在该行上写任何其他内容）时，它都会移动回写的其他内容，这使得解决迷宫变得相当困难。
我一直在改编本教程https://www.youtube.com/watch?v=W1e5wO7XR2w中的代码，尽管似乎没有问题，但似乎没有这个问题。 我正在将C ++与Visual Studio 2017一起使用
#include <iostream>
#include <conio.h>

bool gameover, win; //Condition for gameover or a win
const int width = 20; //Maze Width
const int height = 20; //Maze Height
int x, y, endX, endY; //Coordinates of diffrent objects
bool mazeWallX[20] = { false, false, false, true, false, false, false, false, false, false, false, false, false, false, false, false, false, false, false, false}; //Layers of walls will build up the maze, the bool statments state where there are and arent any walls.
bool mazeWallY[20] = { true, true, true, true, true, true, false, false, true, true, true, true, true, true, true, true, true, true, false, false };

答案 0 :(得分：0)
在for循环中，就像在图形中那样给出屏幕终点的条件，我们可以给getmaxx（）自动检测x坐标的最大屏幕长度，这样可以添加头文件
graphics.h ##头文件
然后使用getmaxx（）检测x，然后使用getmaxy（）检测y，如果它不起作用，可以使用它，然后用我自己的方式评论我。

好的，我想我已经解决了
void Draw() //Draws the player and walls on board, in command line.
{
system("cls");
for (int i = 0; i < width+2; i++) //Draws top boarder
cout << "#";
cout << endl;
for (int i = 0; i < height; i++) //Draws vertical walls, exit and player
{
for (int j = 0; j < width; j++)
{
if (j == 0 || (mazeWallX[j]&&mazeWallY[i]) || (mazeWallX2[j] && mazeWallY2[i]) || (mazeWallX3[j] && mazeWallY3[i]) || (mazeWallX4[j] && mazeWallY4[i]) || (mazeWallX5[j] && mazeWallY5[i])) //Will draw a wall as indicated by the
cout << "#";
else if (i == y && j == x) //Draws player
cout << "O";
else if (i == endY && j == endX) //Draws exit
cout << "E";
else
cout << " ";
if (j == width - 1)
cout << "#";
}
cout << endl;
}
for (int i = 0; i < width+2; i++) //Bottom wall
cout << "#";
cout << endl;
}
我在cout <<“”前面添加了else；并更改了// //将Exit绘制到，否则，则每行写入正确的字符数。感谢@ 1201ProgramAlarm的提醒。
