MessageBox Tutorial/External Menu Selection

This is a subsection of the MessageBox Tutorial, and uses this script as a base. The following code may or may not require certain aspects of that script to work, however the information should prove useful for any script (it will take a bit of care to make it work, though).

---

As it's setup now, the first menu the player sees will always be the same. If you want to start with a different menu, set Choosing to your desired menu, as such:

set YourActivator.Choosing to -2 ;the "Food" menu in the example
YourActivator.Activate player, 1

You need to make one small change to your menu script as well. Change

begin onActivate
  set Choosing to -1
...

to

begin onActivate
  if (Choosing == 0)
    set Choosing to -1
  endif
...

Also, if you want to allow the menu to be reset if it's still trying to catch the player's choice (GetButtonPressed keeps returning -1), then use

  if (Choosing >= 0)

instead.
