In the mod i'm making i'd like it to be possible for the player to know that certain items are more deeply interacteable, ie it's possible to poison a barrel of water with magical posion dart, or use a lore skill on something to find out about it. The ideal way for this to work is that if the player hovers over the item with the mouse cursor turns the mouse cursor into those little gears and the item becomes outlined with white. What i'm wondering is if it's possible to make any item react this way to when the player puts the mouse cursor over it, like a ship or a tree for example, or is that somehow hardcoded into certain items like chairs?
