I almost finished my project, but I can't change any colours of windows or text.
I tried attron and attroff but it doesn't work. All is compiled, but nothing happened, still default colours. Wattron doesn't work either.

attron(COLOR_PAIR(1));
mvwaddch(win, obj2_y, obj2_x, ' ');
you've turned color-pair-1 on in stdscr, but are adding characters to win (a different window). The attron only affects the window you're setting the attributes on. That's likely the problem you're seeing.
In another place, you're doing getch (for stdscr), which can interfere with refresh's for win, but it seems that you've added wrefresh's to compensate for that.
