Hello, I have a problem. When I try to move a bitmap above an another bitmap, sometimes the program exit without any message.. where is the error.. One bitmap has the coord of my mouse (x,y).. and another is fixed. If I don't move a bitmap above an another bitmap everything it's ok but I need to pass over it in order to increase the "score"... Sorry for my bad english.
This is the code:

I don't know, I've started to learn allegro 5 three days ago because I need it for a project..

I've put
al_set_target_bitmap(player);
al_set_target_bitmap(player2);
al_draw_bitmap(player2, x2, y2, ALLEGRO_FLIP_HORIZONTAL);
al_draw_bitmap(player, x, y, ALLEGRO_FLIP_HORIZONTAL);

and I've received this error:

You need to wrap the switch (events.keyboard.keycode) { switch in an if statement that verifies that the event type is ALLEGRO_EVENT_KEY_DOWN (or similar keyboard event).

Good stuff!
