Right, I'm currently mucking about with allegro, with the goal of creating a
little game like one I used to have on ancient 5 1/4 disks, called Space-War
(an overhead shooty thing on one screen, one player against the other, with
the option of sticking a planet in the middle... it's really old,
anyway...). My problem is that the program (which follows) does not seem to
want to read from the keyboard. In fact, after a few button presses, the
computer starts bleeping at me in an annoyed manner.... here's the code (it
compiles fine...):


#include <stdio.h>

#include <allegro.h>
#include <duel.h>



int main()
 {


  int angle;
  BITMAP *buffer; /*for double buffer*/
  /* BITMAP *player; /*for player sprite*/
  BITMAP *enemy; /*for comp, player 2 sprite*/
  RGB pal[255];  /*for palette*/

  allegro_init;   /*load allegro*/
  install_timer;  /*allegro timer*/
  install_keyboard; /*allegro keyboard routines */

  set_color_depth(16);
  set_gfx_mode(GFX_VESA3,640,480,0,0);  /* set gfx mode, 640*480, no
'virtual'*/


  /*load the graphics files*/
    /*ships*/

      /*player = load_bitmap("green.bmp",pal); not suing this just yet, only
testing stuff */
      enemy = load_bitmap("orange.bmp", pal);

            /*to do later, once everything else works:
              make a sprite selection screen*/

    /*other graphics*/
     /*none as yet*/
  /*set palette to that of graphics files*/
  set_palette(pal);

    /* create and clear double buffer */
   buffer = create_bitmap(640,480);
   clear(buffer);
   clear(screen);

  /*main loop*/

  clear_keybuf;
  angle=0;
  do
  {
   if(key[KEY_RIGHT]) angle++;
   if(key[KEY_LEFT]) angle--;
   if(angle>255) angle=0;
   if(angle<0) angle=254;
   clear(buffer);
   rotate_sprite(buffer, enemy, 310,230, itofix(angle));
   blit(buffer,screen,0,0,0,0,640,480);
  }while (!key[KEY_ESC]);


  /*destroy_bitmap(player);*/
  destroy_bitmap(enemy);
  destroy_bitmap(buffer);
  exit(0);

}


am I doing something wrong? missing something?
