Items and objects searching for and communicating with each other is a good thing to put a little focus into for core mica nicks and modding. Allowing one item or object to check for the preasence of others in the general area is exstreamly usefull
For instance having a crafting table, tool rack, and some chests near buy could allow you to use the items in the chest and tools on the rack to craft something with out actually having to get them. The crafting table checks to see if there available and shows that the object can be crafted and uses the items to do so.
Or you could have say a magical totem that will link with near by gemstones and the more it detects around it the more power it gains. This could allow them to be in chests or demand that they be placed in the world on blocks around it.
Magical nodes that detect magical items an recharge them.
NPCs that see you have an item and ask for it.
Stuff like this make it something I think people overlook far to often. It’s something very simple some modders have worked into the game in the past but having it included in core gameplay and modding tools will open it up to more people that understand it less.
