Can't you check if variable x and y is a specific number, if so then create the fight menu ..
You can make it have a variable for the position in its create event, maybe call it "pos"
After moving it then set the variable
pos
to
(x==202)*2 + (y==202)
in all of the direction events
That way pos will be the value 0 to 3
And you can check:
Code:
if space is pressed
if pos is 3
destroy trainer(or create the menu)
you might also want to disable controls of this menu if it some of the other menus exist
