Porting speed

Jefferson Almeida

In Allegro 4 I have to use this speed_counter, in the Allegro5 is automatically replaced by the functions of timer?

#SelectExpand
  1volatile long speed_counter = 0;
  2void increment_speed_counter()
  3{ speed_counter++;
  4} END_OF_FUNCTION(increment_speed_counter);

  6
  7int frames = 0;
  8int desce = 0;
  9void mais_frame()
 10{
  if(frames==0) desce = 0;
  if(frames==2) desce = 1;
  if(desce==1) frames--;
  else frames++;
 15} END_OF_FUNCTION(mais_frame);

 18void draw_character(BITMAP **layer, int my_pic_x, int my_pic_y, int move, int walking, int direction)
 19{
if(walking==1)
  {
         switch(move)
         {
               case 2:
               if(frames==0) draw_sprite(*layer, p21, my_pic_x+5, my_pic_y+83);
               else if(frames==1) draw_sprite(*layer, p22, my_pic_x+5, my_pic_y+83);
               else if(frames==2) draw_sprite(*layer, p23, my_pic_x+5, my_pic_y+83);
               else draw_sprite(*layer, p22, my_pic_x+5, my_pic_y+83); break;
               case 4:
               if(frames==0) draw_sprite(*layer, p41, my_pic_x+5, my_pic_y+83);
               else if(frames==1) draw_sprite(*layer, p42, my_pic_x+5, my_pic_y+83);
               else if(frames==2) draw_sprite(*layer, p43, my_pic_x+5, my_pic_y+83);

               else draw_sprite(*layer, p62, my_pic_x+5, my_pic_y+83); break;
               case 8:
               if(frames==0) draw_sprite(*layer, p81, my_pic_x+5, my_pic_y+83);
               else if(frames==1) draw_sprite(*layer, p82, my_pic_x+5, my_pic_y+83);

I think you should look in the manual and at least make an attempt at a solution before getting people here to port your code for you section by section .

Jefferson Almeida

Me too... but the API reference from allegro 4... http://alleg.sourceforge.net/stabledocs/en/allegro.html/
edit1: and I already try a solution

Edgar's link is to the Allegro 5 reference manual. You can also use docs.liballeg.org as an easy to remember address.

Jefferson Almeida

Thanks guys! I changed the 5 for 4 : http://www.allegro.cc/manual/4/ and work!

Matthew Leverton

An Allegro 4 timer that only increments a variable can be done like this with Allegro 5:

ALLEGRO_TIMER *t = al_create_timer(1 / 60.0);
al_start_timer(t);

al_get_timer_count(t); // same as speed_counter

However, in most cases you'll just use al_register_event_source(queue, timer) and watch for timer events.
