我一直在控制台中设计一款 roguelike 视频游戏。

我的问题是我最初使用 writeconsoleoutput 一次绘制整个地图，然后使用 writeconsoleoutputcharacter 重新绘制必要的内容。但我发现它在右侧画了一个额外的像素厚。这实际上从右侧的图块上擦除了一个像素。

有谁知道让它停止绘制字符并在字符右侧添加 1 个像素的空白区域的方法。

编辑：我发现的一种解决方法是重新绘制玩家踩踏的线条，但有时我会注意到闪烁，这并不完美。最好只在单个基础上重绘字符而不在末尾附加任何像素。或其他任何地方。用于打印字符的代码

void printchar(char character, COORD location,short color)
{
    const char *pointer = &character;
    //short LENGTH = 1;
    DWORD dwWritten = 0;
    std::vector<WORD> attributes;attributes.clear();;
    setAttributesChar(color,attributes);//Pushes back the color
    if(attributes.size() == 1)
    {    WriteConsoleOutputAttribute(GetStdHandle(STD_OUTPUT_HANDLE),&attributes[0], attributes.size(), location, &dwWritten);
        WriteConsoleOutputCharacter(GetStdHandle(STD_OUTPUT_HANDLE), pointer, attributes.size(), location, &dwWritten); 
    }
}

void setAttributesChar(short color,std::vector<WORD> &attributes)
{
    switch(color)
    {
    case DEFAULTCOLOR:
        attributes.push_back(FOREGROUND_INTENSE_WHITE);return;
    case HOVEREDCOLOR:
        attributes.push_back(FOREGROUND_GREEN);return;
    case RED:
        attributes.push_back(FOREGROUND_RED);return;
    case GOLD:
        attributes.push_back(FOREGROUND_INTENSE_YELLOW);return;
    case REDWHITE:
        attributes.push_back(COMBINED_REDWHITE);return;
    case YELLOWPURPLE:
        attributes.push_back(COMBINED_YELLOWPURPLE);return;
    case NPCCOLOR:
        attributes.push_back(FOREGROUND_INTENSE_CYAN);return;
    case PURPLE:
        attributes.push_back(FOREGROUND_MAGENTA);return;
    case REDPURPLE:
        attributes.push_back(COMBINED_REDPURPLE);return;
    case BLUE:
        attributes.push_back(FOREGROUND_BLUE);return;
    case BLUEPURPLE:
        attributes.push_back(COMBINED_BLUEPURPLE);return;
    case INTENSEGREEN:
        attributes.push_back(FOREGROUND_INTENSE_GREEN);return;
    case REDGREEN:
        attributes.push_back(COMBINED_REDGREEN);return;
    case BWHITE:
        attributes.push_back(BACKGROUND_WHITE);return;
    }
}

我创建了一个工作示例，你们可以编译（假设您使用 Windows）来查看发生了什么。在其中我创建了一个控制台，设置大小用 asci 符号 223 填充屏幕。然后我使用 Writeconsoleoutchar 打印一个绿色的 223 符号。您可以看到额外绘制的黑色像素线。

#include <windows.h>
#include <cwchar>
#include <vector>
enum COLORS{HOVEREDCOLOR};
void setAttributesChar(short color,std::vector<WORD> &attributes)
{
    switch(color)
    {
    case HOVEREDCOLOR:
        attributes.push_back(FOREGROUND_GREEN);return;
    }
}
void printchar(char character, COORD location,short color)
{
    const char *pointer = &character;
    //short LENGTH = 1;
    DWORD dwWritten = 0;
    std::vector<WORD> attributes;attributes.clear();;
    setAttributesChar(color,attributes);//Pushes back the color
    if(attributes.size() ==1)
    {      WriteConsoleOutputAttribute(GetStdHandle(STD_OUTPUT_HANDLE),&attributes[0], attributes.size(), location, &dwWritten);
        WriteConsoleOutputCharacter(GetStdHandle(STD_OUTPUT_HANDLE), pointer, attributes.size(), location, &dwWritten); 
    }
}
#define SCREENWIDTH 1550
#define SCREENHEIGHT 850
void SETWINDOWUP(DWORD &SIZE)
{
    CONSOLE_SCREEN_BUFFER_INFO info;
    MoveWindow(GetConsoleWindow(),0,0,SCREENWIDTH,SCREENHEIGHT,true);         //MOVE WINDOW TO 0,0 AND MAKE 1600 BY 880
   ::SetWindowPos(GetConsoleWindow(), HWND_TOPMOST, 0, 0, 0,0,     SWP_DRAWFRAME | SWP_NOREPOSITION | SWP_NOMOVE | SWP_NOSIZE | SWP_SHOWWINDOW); //SET WNDOWS POSITION COMPARED TO OTHER WINDOWS IN DRAW ORDER
::SetWindowPos(GetConsoleWindow(),HWND_NOTOPMOST, 0, 0, 0, 0, SWP_DRAWFRAME | SWP_NOMOVE | SWP_NOSIZE | SWP_SHOWWINDOW);
HANDLE hout = GetStdHandle( STD_OUTPUT_HANDLE);
GetConsoleScreenBufferInfo(hout,&info);
COORD newBuffersize =
{
    info.srWindow.Right - info.srWindow.Left + 1,
    info.srWindow.Bottom - info.srWindow.Top + 1

SetConsoleScreenBufferSize(hout,newBuffersize);

    FillConsoleOutputCharacter(GetStdHandle(STD_OUTPUT_HANDLE),CHARACTER,SIZE,start,&charswritten);
Sleep(500);
printchar(223,{6,5},HOVEREDCOLOR);
Sleep(500);
return 0;
};
