I am working on a game in allegro 5 in which I want to create rectangular objects dynamically on screen and make them clickable with mouse buttons
al_register_event_source( event_queue, al_get_timer_event_source(timer));
al_register_event_source( event_queue, al_get_mouse_event_source());
al_clear_to_color(al_map_rgb(0, 0, 0));
al_flip_display();
al_start_timer(timer);
while ( !exit )
{
ALLEGRO_EVENT ev;
al_wait_for_event( event_queue, &ev);
if (ev.type == ALLEGRO_EVENT_TIMER)
;
else if ( ev.type == ALLEGRO_EVENT_MOUSE_AXES )
{
x = ev.mouse.x;
y = ev.mouse.y;
}
else if ( ev.type == ALLEGRO_EVENT_MOUSE_BUTTON_DOWN )
{
if ( x >= rect.x && x <= rect.maxx && y >= rect.y && y <= rect.maxy )
destory ( rect );
}
else if ( ev.type == ALLEGRO_EVENT_DISPLAY_CLOSE )
break;
if ( redraw && al_event_queue_is_empty(event_queue)){
redraw = false;
al_draw_rectangle ( rect.x, rect.y, rect.maxx, rect.maxy, blue, 1 );
al_flip_display();
al_clear_to_color(al_map_rgb(0, 0, 0));
}
}
But this is hardcoded for only one rectangle. How can I make an event for this which can handle rectangles like button.
