I have a big menu overlay that pops up from time to time, covering my regular object-based buttons. The menu is not an object -- I detect UI touches using mouse_check_button(). Is there a way that when I detect mouse down and handle the mouse click in my menu overlay, I can then cancel the mouse from going on and triggering the buttons underneath? I know that with button click handling you can return true to say the event was handled. But in the case of mouse_check_button, there's no event (yet?). So can I get the event that is or would be generated and cancel that? Thanks!
