Windows (or Transparent barriers), in context of Roll20's Dynamic Lighting, are sections of "wall" that allows sight to pass through, but stops movement of tokens. They can be created with APIs.

Older, no longer working
When proper Windows where released, older Mods relying on tricks to simulate windows stopped working. Here are some of them.
- DoorKnocker -- Script helps quickly open and close doors by controlling the dynamic lighting lines.
- v1.211 Introduces option to create "windows"
- UDLWindows(Forum) -- API for creating or converting DL lines to be see-through, but still block movement
- Converting DL circles to windows works
- sourcecode
Passwall A related trick to Windows is to create hidden passages which blocks sight, but doesn't stop movement. Great for illusionary walls, hidden areas, or to limit vision in thick fog.
- UDLPasswall(Forum) - Walls that block sight, but not movement
- Aug 2022 - roll20 updates might have broken the API hack it was relying on, and might no longer work: https://app.roll20.net/forum/post/11054234/help-udl-passwall-no-longer-working
History of the Trick
In late 2020, Andreas J. realized that by creating a Free-hand drawing on any of the other b Layers than the DL-layer, and then moving it to the DL layer, it only partially blocked sight, but always blocked movement. After the discovery, TheAaron and Scott C. created APIs that can create windows much easier. Drae Acevedo saw an earlier version of this when using the circle tool.
