Problem with a menu for a game
Author
Hello. I got some problem with a menu for my new game project. The menu consists of some text stored in SDL surfaces, and when somebody click on one of those options, the function I'm writing on should return the identifier for that option.
The function looks like this:
The problem is that when I click on the first option, 1 is printed out. And on the second, 2, the third, 3, the fourth 4 and the fifth nothing happens. It should print 0, when I click on the first option etc.
Anybody got an idea what I'm doing wrong?
(Gah, I have programmed too many hours in row. So it's probably a silly mistake. :P)
Thanks in advance.
Hmm... the code above looks ok to me. Try posting the code where you initialize the menu options surfaces.

OK, here I initialize the menu option surfaces:
void menu_show(void){ int i; TTF_Font *font, *heading_font; SDL_Surface *menu_bg_surface; SDL_Surface *menu_heading; SDL_Color text_color; SDL_Rect src_rect, dest_rect; /* Load the fonts. */ font = TTF_OpenFont(MENU_FONT, MENU_FONT_SIZE); if (font == NULL) { fprintf(stderr, "Couldn't load font.\n"); exit(1); } heading_font = TTF_OpenFont(MENU_HEADING_FONT, MENU_HEADING_FONT_SIZE); if (heading_font == NULL) { fprintf(stderr, "Couldn't /* Generate text for the menu options. */load heading font.\n"); exit(1); } /* Load and blit the background. */ menu_bg_surface = SDL_DisplayFormat(IMG_Load(MENU_BACKGROUND_IMAGE)); if (menu_bg_surface == NULL) { fprintf(stderr, "Couldn't load the menu background image.\n"); exit(1); } src_rect.x = src_rect.y = dest_rect.x = dest_rect.y = 0; src_rect.w = dest_rect.w = menu_bg_surface->w; src_rect.h = dest_rect.h = menu_bg_surface->h; SDL_BlitSurface(menu_bg_surface, &src_rect, display_surface, &dest_rect); /* Generate the heading text. */ text_color.r = text_color.g = text_color.b = 0; menu_heading = SDL_DisplayFormat(TTF_RenderText_Solid(heading_font, MENU_HEADING, text_color)); src_rect.w = dest_rect.w = menu_heading->w; src_rect.h = dest_rect.h = menu_heading->h; dest_rect.x = (WIDTH - menu_heading->w) / 2; dest_rect.y = 40; SDL_BlitSurface(menu_heading, &src_rect, display_surface, &dest_rect); /* Generate text for the menu options. */ dest_rect.y = 70; for (i = 0; i < MENU_NUM_OPTIONS; i++) { menu_options_surfaces.surface = SDL_DisplayFormat( TTF_RenderText_Solid(font, menu_options, text_color)); if (menu_options_surfaces.surface == NULL) { fprintf(stderr, "Couldn't generate text fot the menu options.\n"); exit(1); } src_rect.w = dest_rect.w = menu_options_surfaces.surface->w; src_rect.h = dest_rect.h = menu_options_surfaces.surface->h; dest_rect.x = menu_options_surfaces.x = (WIDTH - menu_options_surfaces.surface->w) / 2; menu_options_surfaces.y = dest_rect.y; dest_rect.y += menu_options_surfaces.surface->h + 10; SDL_BlitSurface(menu_options_surfaces.surface, &src_rect, display_surface, &dest_rect); } SDL_UpdateRect(display_surface, 0, 0, 0, 0);}This topic is closed to new replies.
