SetConsoleCursorPosition:使用时在控制台中获取黑色行

问题描述 投票:1回答:1

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");
    }
}

    for (int i = 0; i < Nbligne; i++)
    {
        for (int j = 0; j < Nbcolonne; j++)
        {
            tab[i][j] = ' ';
            if (i == 0 || i == Nbligne - 1)
                tab[i][j] = 205;
            if (j == 0 || j == Nbcolonne - 1)

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SetConsoleCursorInfostruct
