我几乎完成了我的项目,但我无法改变任何颜色的窗户或文字
我尝试了attron
和attroff
,但它不起作用。全部编译,但没有任何反应,仍然是默认颜色。 Wattron也没有工作。

答案 0 :(得分:3)
在这个块中
attron(COLOR_PAIR(1));
mvwaddch(win, obj2_y, obj2_x, ' ');
您已在stdscr
中启用了颜色对1,但正在向win
添加字符(不同的窗口)。 attron
仅影响您在其上设置属性的窗口。这可能是你所看到的问题。
在另一个地方,您正在执行getch
(对于stdscr
),这可能会影响win
的刷新,但您似乎在&#39 ; ve添加了wrefresh
来弥补这一点。
