I am making a function which is creating a new bitmap with circle on it, and returning that bitmap. Something like this:
1function(int w,int h,ALLEGRO_COLOR color)
2{
3ALLEGRO_BITMAP* temp = al_create_bitmap(w,h);
4al_set_target_bitmap(temp);
5al_draw_filled_ball(w/2,h/2,(w>h)?(w/2):(h/2),color);
6return temp;
7}
But then i have an error, because and after i called this function target is non-exciting local bitmap "temp". I thought of it, and i had an idea. Is there a function which return pointer to current bitmap? Like this:
1function(int w,int h,ALLEGRO_COLOR color)
2{
3ALLEGRO_BITMAP* current_target_bitmap = al_magic_function();
4ALLEGRO_BITMAP* temp = al_create_bitmap(w,h);
5al_set_target_bitmap(temp);
6(...)
7al_set_target_bitmap(current_target_bitmap);
8return temp;
I couldn't find that sort of function. Maybe there is other way? The sending display to function is the last help, i really wanna this function to be self-sufficient.
