    This won't compile

    this will not compile

    Code:
    #include <allegro.h>
    
    int main() 
    {        
     allegro_init();      
     set_gfx_mode(GFX_AUTODETECT, 640,480,0,0); 
     install_keyboard();
     set_color_depth(16);
    /******************** Main Menu **************************************/
     while (!key[KEY_ESC]){
     BITMAP *main; 
     main = load_bitmap("main.bmp", NULL); 
     
     acquire_screen();
     
     blit(main, screen, 0,0,0,0,640,480); 
     
    
     if (key[KEY_1]||key[KEY_1_PAD])
     {clear_to_color(screen, 0);
       readkey();
     }
     
     if (key[KEY_2]||key[KEY_2_PAD])
     {clear_to_color(screen, 1);
       readkey();
     }
     
     if (key[KEY_3]||key[KEY_3_PAD])
     {clear_to_color(screen, 2);
       readkey();}
     } 
     release_screen();
    
     destroy_bitmap(main);//error here
     allegro_exit();
     return 0;     
    }     
    
    
    END_OF_MAIN();
    this is the error I get

    it's name is main!!! the compiler is gonna think you mean the main function, this name is reserved use something else, like 'mainbmp' or something.

    do it like this instead

    Code:
    #include <allegro.h>
    
    void setup();
    void load();
    
    BITMAP *bmp;
    BITMAP *buffer;
    
    int main() 
    {        
     
     setup();
     load(); 
     
     blit(main, buffer, 0,0,0,0,SCREEN_W,SCREEN_H); 
     blit(buffer, screen, 0,0,0,0,SCREEN_W,SCREEN_H);
    
    while(!key[KEY_ESC])
     { 
    
     if (key[KEY_1]||key[KEY_1_PAD])
     {clear_to_color(buffer, 0);
       clear_keybuf();
     }
     
     if (key[KEY_2]||key[KEY_2_PAD])
     {clear_to_color(buffer, 1);
       clear_keybuf();
     }
     
     if (key[KEY_3]||key[KEY_3_PAD])
     {clear_to_color(buffer, 2);
       clear_keybuf();
     }
    
     acquire_screen();
     blit(buffer, screen, 0,0,0,0,SCREEN_W,SCREEN_H); 
     release_screen();
    
     }
    
    allegro_exit();
    return 0;     
    }     
    
    END_OF_MAIN();
    
     
    void setup()
     {
     allegro_init(); 
     install_keyboard(); 
     set_color_depth(32);    
     set_gfx_mode(GFX_AUTODETECT, 640,480,0,0); 
     }
    
    void load()
     {
      bmp = load_bitmap("main.bmp", NULL); 
      buffer = create_bitmap(SCREEN_W, SCREEN_H);
     }
    
    /* I did not compile this code so there might be a few parse errors or something like that, but I don't think there are any.  All in all, though, the basic concept of the code works for sure.
    If you have any further questions, then just ask them. However, I probably won't be able to answer them until later. Btw, allegro.cc is a very good site for allegro users.

    Thanx Guys

    Your suggestions worked. But now I have another question. what is the input text function for allegro. I want the user to input their name and I can't seem to find any referances to an input function in allegro.

    Code:
    char name[15];
    cin >> name; //include iostream.h
    or if you want spaces
    Code:
    char name[15];
    cin.getline(name, 15);
    i didn't answer your question did i

    I'm assuming your not talking about regular game input, rather large strings input. Like typing in your name for a character or something like that, right?

    Well, if so then this link at allegro.cc could be useful:
