C++ ile yeni bir Allegro denemesi

Allegro ve c++ ikilisi oyun programlama da ne kadar yeterli bilemem fakat bana çok zevkli gelmeye başladı. İşte size yeni bir örnek daha:

/* ========================================================================== */
#include <allegro.h>
/* ========================================================================== */
#define BCK_CLR 0
#define MAX_X (SCREEN_W-294)
#define MIN_X 0
/* ========================================================================== */
BITMAP *buffer;
BITMAP *bmp;
BITMAP *crs;
int _x = 0, _y = 80, speed = 2;
/* ========================================================================== */
void ShowGosteri()
{
     textout_ex(buffer, font, "C++ ile Allegro Denemesi",
                 SCREEN_W/2-150, 10, makecol(0,100,255), BCK_CLR);
     draw_sprite(buffer, bmp, _x, _y);
     draw_sprite(buffer, bmp, _x*-1+(SCREEN_W-294), _y+175);
     
     textout_ex(buffer, font, "Cikis icin [ESC] tusuna basin!",
                 SCREEN_W/2-150, SCREEN_H/2+200, makecol(0,100,255), BCK_CLR);
}
/* ========================================================================== */
void main()
{
     allegro_init(); //initialize
     install_keyboard(); //install keyset
     install_mouse(); //mouse install
     
     set_window_title("Allegro"); //window title
     set_color_depth(desktop_color_depth()); //color depth
     set_gfx_mode(GFX_AUTODETECT_FULLSCREEN, 800, 600, 0, 0); //screen mode
     
     buffer = create_bitmap(SCREEN_W, SCREEN_H); //buffer create
     bmp = load_bitmap("./bmp.bmp", 0);
     crs = load_bitmap("./cursor.bmp", 0);

     set_mouse_sprite(crs);
     
     while(!key[KEY_ESC])
     {
         show_mouse(buffer);
         _x+=speed;
         
         if(_x >= MAX_X)
         {
               speed*=-1;
         } else 
         if(_x <= MIN_X)
         {
               speed*=-1;
         }
         
         draw_sprite(screen, buffer, 0, 0);
         clear_to_color(buffer, BCK_CLR);
         ShowGosteri();
     }
     
     allegro_exit();
     
} END_OF_MAIN();
