使用 ncurses 为游戏创建 "main" window

Question

我正在尝试创建一个 window 作为我整个游戏的边框。所以它将是 "main" window。我发现最好的方法是创建一个 "ghost" window 和另一个你将使用的真实的，在它的内部尺寸略小。

但我仍然不能正确地创建它：这是我最好的解决方案。

#include <ncurses.h>

WINDOW* createWindow(int, int, int, int);
WINDOW* createRealWindow(int, int, int, int);

int main ()
{
    initscr();
    cbreak();

    char str[50];
    WINDOW *back_window, *real_window;
    int height=12, width=80;
    int x=(COLS-width)/2, y=(LINES-height)/2;

    back_window = createWindow(x, y, width, height);
    real_window = createRealWindow(x+1, y+1, width, height);
    wprintw(real_window, "Type: ");
    wgetstr(real_window, str);
    wrefresh(real_window);
    wprintw(real_window, "You typed %s.", str);
    wrefresh(real_window);

    napms(5000);
    endwin();

    return 0;
}

WINDOW* createWindow(int x, int y, int height, int width)
{
    WINDOW *local;

    local = newwin(width, height, y, x);
    box(local, 0, 0);
    wrefresh(local);

    return local;
}

WINDOW* createRealWindow(int x, int y, int height, int width)
{
    WINDOW *local;

    local = newwin(width-2, height-2, y+1, x+1);
    box(local, ' ', ' ');
    wrefresh(local);

    return local;
}

这是我的输出： my output

谢谢大家！

编辑：我已经找到了下面代码的解决方案，但我不知道这在其他分辨率不同的计算机上会有什么表现。想法？ PS：我使用 1920 x 1080。

int main ()
{
    initscr();
    cbreak();

    char str[50];
    WINDOW *back_window, *real_window;
    int height=22, width=78;
    int x=(COLS-width-1)/2, y=(LINES-height-2)/2;

    back_window = createWindow(x, y, width, height);
    real_window = createRealWindow(x+1, y+1, width, height);
    wprintw(real_window, "Type: ");
    wgetstr(real_window, str);
    wrefresh(real_window);
    wprintw(real_window, "You typed %s.", str);
    wrefresh(real_window);

    napms(5000);
    endwin();

    return 0;
}

WINDOW* createWindow(int x, int y, int height, int width)
{
    WINDOW *local;

    local = newwin(width+2, height+2, y, x);
    box(local, 0, 0);
    wrefresh(local);

    return local;
}

WINDOW* createRealWindow(int x, int y, int height, int width)
{
    WINDOW *local;

    local = newwin(width, height, y, x);
    wrefresh(local);

    return local;
}

back_window没有出现，因为real_window遮住了它（由于size/position).但是使用 subwin 是执行此操作的首选方法：

#include <ncurses.h>

int main ()
{
    initscr();
    cbreak();

    char str[50];
    WINDOW *back_window, *real_window;
    int height=12, width=80;
    int x=(COLS-width)/2, y=(LINES-height)/2;

    back_window = newwin(height, width, y, x);
    box(back_window, 0, 0);
    wrefresh(back_window);

    real_window = subwin(back_window, height-2, width-2, y+1, x+1);

    wprintw(real_window, "Type: ");
    wgetstr(real_window, str);
    wrefresh(real_window);
    wprintw(real_window, "You typed %s.", str);
    wrefresh(real_window);

    napms(5000);
    endwin();

    return 0;
}
