How does it work precisely? Because I've used this function inside inventory items and at the moment isn't working.
I mean it auto assigns USE item WITH instead of USE only (that I need for certain items).
What you do is append >u to the item's name. Say you have a flashlight; just call it "flashlight>u".
Then add an "interact with inv item" function.
I remembered this thing for hotspots and was working also for some of my inventory items at the beginning, maybe I've deleted something...
[EDIT]
Ok working again. Thanks
