Well, how can I make this:
When you use give the item to some npc player, he says something and you will be placed to an a new room?
use the interactions editor to put a:
conditional 'if inventory item was used'
under
'player uses inventory on character'
and then under the coniditional make a
'Game - Display a Message' (remember to make the message in the message editor and set the speaker to the character.)
then add a
'player - goto new room (at specific x y)'
and set it up so it goes to the correct room and co-ords
