I just did two impossible things in Roll20.

I set up the dynamic lighting for every wall in the Great Hall of Brazenthrone in 15 minutes. That's the first impossible thing. The second impossible thing is: I can give you the ability to do this. Except it's not going to take you 15 minutes, it's going to take you 1 minute. And no part of this involves ever setting foot in the Roll20 Marketplace.

Two days ago, I posted something about how I didn't think I'd be able to give you maps with dynamic lighting set up for Roll20. I thought the only way to do that would have been to sell them on Roll20's store. That turned out to be wrong. Well, 90% wrong.

Let's talk about scripts. Specifically, this script. Here's how it works: I draw a line. Then, I turn the line into a series of commands that describe the line. The script then turns those commands into walls on a map. If it sounds complicated, don't worry: I have to do the complicated parts. What you do is super easy:

1. Install the Walls script into your game. You can copy it from here.
2. Make a page and put the map on it. Go to the map layer and select the map.
3. Copy a text file (the commands for that map) and paste it in the chat. Hit send. It takes 10-30 seconds to finish and then you have the walls set up for dynamic lighting.

It's not a complete setup, since it doesn't do doors, but tracing the walls is a large part of the work of setting up dynamic lighting and being able to knock that out in a few seconds is a pretty big deal. Here are three maps and their script commands I made to try this out on: the Great Hall, the Fallen Tower and the Tusk. Note that the fallen tower is 140px per tile and the other two are 70px. The size has to be correct.

I was informed about this by Luke, who DMs a game I'm a player in. I told him I thought this might change some things for the better for a lot of people. If you DM on Roll20 and have a Plus or Pro account, try it out and let me know what you think. This is a very easy thing for me to do and, if you want me to make these for every map in the future, I will. Maybe I'll even sit down and do the backlog at some point.

EDIT: You may want to turn off advanced fog of war on maps where you apply the walls with this script. It seems to cause a lot of lagging.
