在我的previous question关于使蛇程序变得更加流畅之后，我去尝试了ANSI转义序列和控制台功能，将文本光标放回左上角。
我希望将光标放在屏幕的左上角，但是当它这样做时，我会在屏幕的每隔一行得到黑色条纹。
我在Windows环境中工作，为Windows控制台制作此程序。
这是绘画功能：
void paint(int tab[28][120], int ligneMax, int colonneMax, HANDLE hconsole)
{
//system("cls");
//printf("\033[1;1H");
COORD destCoord;
destCoord.X = 0;
destCoord.Y = 0;
SetConsoleCursorPosition(hconsole, destCoord);
for (int i = 0; i < ligneMax; i++)
{
for (int j = 0; j < colonneMax; j++)
{
printf("%c", tab[i][j]);
}
printf("\n");
}
}
我在调用paint函数之前尝试将转义码和控制台函数放在右边，但我得到了相同的结果。
如果有人想测试，这是整个程序：
#include <stdio.h>
#include <stdlib.h>
#include <conio.h>
#include <Windows.h>
void paint(int tab[28][120], int ligneMax, int colonneMax, HANDLE hconsole)
{
//system("cls");
//printf("\033[1;1H");
COORD destCoord;
destCoord.X = 0;
destCoord.Y = 0;
SetConsoleCursorPosition(hconsole, destCoord);
for (int i = 0; i < ligneMax; i++)
{
for (int j = 0; j < colonneMax; j++)
{
printf("%c", tab[i][j]);
}
printf("\n");
}
}

要快速接收的代码太多。如果你有蛇的Windows控制台输出，你不能简单地qazxsw poi下一行并留下它吗？
如果你想隐藏光标（而不是试图将它停在视线之外）你可以通过调用printf使它变得不可见，并且传递的SetConsoleCursorInfo是struct。
