The interactable property is useful to prevent static objects from being accidentally moved by players. However, in RPG games there are lots of objects which should not be interactable by players and should be interactable by the GM (host).
It would be ideal if the object interactable property worked like the visibility property in that instead of being a true/false, it would be a string of player colors which are able to interact with that object. An empty string would mean no interaction with any players (i.e. the equivalent of the current interactable = false). Listing all player colors would allow all players to interact with the object (i.e. the equivalent of the current interactable = true). However, listing some player colors (such as black) would allow only those players to interact with the object.
