Getting items in immediate vicinity

[mythikos]

I am rather new to the ESO modding scene, and I was wondering, is it possible to loop through all items in the area surrounding you, or all items in the current zone, etc? I would like to write an addon that notifies the users when they are near certain items (conditionally) but I can't see to find a way.

An example might be, a player enters a dungeon. Is there a way to constantly poll the surrounding area and tell the user a chest or bag is nearby? Or perhaps if an item in the world in nearby (common shields, swords, etc)?

Any help or direction would be greatly appreciated.
