ah... well this is overly complicated
must script a must_have variable for non-player troops, and then i must script a get_water condition where if docked at any town or city regen item water every x amount of days... then I must add some kind of script to trigger party slow down if troop x,y,d,a,b,etc,etc,etc does not have item_water in inventory for x amount of days, and somehow script a priority to get to a town ASAP to remove this condition.....
then i must add beast parties that do not have these scripts, and then i need to make sure player troop is effected as well as npc troops.
is it possible to also script it then when docked whenever item_water is added to inventory a certain amount of money is deducted everytime it is added? but then... I'd have to add a special Buy Water menu option for each town or what?
