Placing Doors and Windows on Roll20 (Jan. 2023)

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.

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.

[edit] 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.

Roll20 Trick - Dynamic Lighting "Windows" (UDL only)(Forum)

Until May 2021, it was possible for
Plus
info-subscribers to create "windows" by drawing shapes with the free-hand tool on another layer, and then move it to the DL layer. This was due to Roll20 updating Dynamic Lighting to make freehand & eclipse drawings work properly as DL lines, which inadvertently made the windows inaccessible to Plus users.

In April 2022 when Roll20 started developing integrated version of "windows", the API-based tricks stopped working. udl-doorknocker-and-windows issues

Transparent barriers where in early access for Pro users. Several of mods where updated to handle the new "windows". Proper Windows and Doors where released as feature for Plus and Pro users.
