Thread: pic movement

hi

this code is to get a pic keep moving it's worked in BGI but without pictures now i tried it in allegro and it doesn't show a thing

can u see what i'm doing wrong or do u know a better way to get the pic move till next keypress?

Code:

#include <allegro.h>
#include <stdlib.h>
#include<conio_mingw.h>




int main()
{
char ror=30;
   quit = 0;
   allegro_init();
   install_keyboard();

   set_color_depth(32);
   set_gfx_mode(GFX_AUTODETECT_FULLSCREEN, 640, 480, 0, 0);

   BITMAP *p1 = load_bitmap( "c:\\temp\\pic1.bmp", NULL );
   BITMAP *p2 = load_bitmap( "c:\\temp\\pic2.bmp", NULL );

   while ( !quit )
{
   while(kbhit())
   {
       ror==getch();

   }
  switch(ror)
                     {
  case 'a':

  ror-- ; draw_sprite( screen, p1, ror, 400 ); break;

    case 'd':

        ror++; draw_sprite( screen, p2, ror, 400 ); break;

    case 'q':  quit = 1; break;

                     }


}


   destroy_bitmap(p1);
   destroy_bitmap(p2);
   allegro_exit();
   return 0;
}
END_OF_MAIN();
