Question for the Dev's Live D&D Stream

Hey Everyone I just wanted to say to the Devs that I enjoy watching your D&D live streams. On a sidebar, Nolan's character losing his hand was honestly one of the most hilarious moments I've seen at a game...it really brought tears to my eyes because I've had moments like this at games past...sorry Nolan I deeply sympathize but that was funny!  I don't catch the live streams in the moment of the stream but watch them as I'm working on my own game during the week.  You guys are all great in my book! That aside I have a question about one of those live streams.  @ Richard Zayas.  In one of them you had a coliseum type adventure with the players in holding cells.  If I'm not mistaken you said that they couldn't see much and were locked in their rooms and they could move around but they couldn't leave the room.  I'm sure it might have been a roleplaying element that the players choose not to move their characters but I was wondering.  I'm curious because I haven't specifically found a "player locked to room" feature in Roll20.  Is there a way to do this technically (specifically to prohibit them from moving about the board uncovering areas with dynamic lighting aside from uncover when dropped feature).  I'm just curious.  I trust my players but I was curious as if this was a feature I haven't uncovered.  If not, it's cool.  I love this virtual tabletop and the fact that it allows me to game with cool folks every game with ease is awesome.  Thanks Again for everyone's hard work and looking forward to more to come. 

Eric, how many of us accomplish what you are asking about is by combining Dynamic Lighting with Fog of War.  In it's current form, FoW is a 'blunt' instrument used to uncover areas. DL is a finer instrument allowing you to control what they see within those areas. How this is used: I set up the DL for a map and then enable FoW. When players are approaching a room I clear it using FoW. I do not pay too much attention to 'fine control' but go a bit beyond the walls etc. I leave it to the DL to do the fine control.  In a map with a lot of odd shaped walls I might make small boxes on the DL layer where a PC is likely to be accidentally dropped. That will limit accidental releases.  Example: A cavern has a wall covering about 2/3 of a square. I expect the PC will try to occupy that square but might forget to hold down the ALT key for proper positioning. After setting up normal DL layer boundries for the wall I will drop a token into the square and then draw a very small square around the light point the token generates (about the center of the token). That way, if the player accidentally steps into that square they still wont see much if anything.  Fog of War will handle squares farther away.  - Gauss

Hey Gauss!  Thank you for the great advice!  I didn't know that they could be used in conjunction like that.  Thanks for the feedback!
