I realized I had created a script that had an emitter, and a measure of distance from emitter to determine the level of sound... I'm guessing a similar use could be door adjacency, to either decide to display a door when a player is close enough, or to lock a door until a player is close enough, but I'm not sure if interaction with doors is restricted and I don't think it is. The moment a player sees a door, anyone can "open" it or interact with it, regardless of all player adjacency.... Player specific audio, player specific vision or visibility of tokens - these are both needed to really enact some of the ideas we've had. GMs already have some ability on the visual side (token visibility restricted by GM status) - but I'm curious if anyone else had ideas about door adjacency and restriction of door/window interaction.
