basically, i need to be able to find out whether any current members of the Player Group possess any Weapons or Armour, either equipped or unequipped
if they do then the Equipment Menu should be accessible, otherwise it should be greyed out
setting a one-off flag at some point during gameplay doesn't work because aside from equipping and unequipping items they could also lose items by having them stolen, or by selling them, so the situation always needs to be dynamically assessed just before displaying the menu
this is REALLY frustrating, because it's such a trivial seeming problem, but i just can't find any obvious solution to it
Edit: Ok, i've hacked a solution: i've removed the Equipment Menu Requirement check, but i've given the player character a start item that can be neither sold nor stolen, and i'll think up some blah-de-blah to explain why he's got it and why he can't get rid of it. that at least means that the Equipment Menu will never be empty
(i'll also use that Lock Equipment Part trick to force him to always wear it)
