KGA said: Brian C. said: This would potentially be a bit difficult to keep organized (which layer, what it means, lining everything up, and duplication of effort if a line should be doing two different things). A lot of the time, the separate layer would not necessarily be needed. A better way to implement this would be making DL lines fully-fledged objects that carry their own data on how they affect vision and movement. The default for new lines can be set along with the current color. A user can then define whether a line blocks movement and vision from each side. Opening a door can be simplified by selecting a line and turning all of its blocking features off (and closed by turning back on again) rather than finding a place to move the line. I think you're misunderstanding this. It would never be used for doors (unless they were glass doors). The current "Dynamic Lighting" handles doors without a problem. It would be used for objects that do not block sight but would block movement (without a Check/Roll). For instance store counters, windows, transparent force fields, cars, bar counters, hedges, edges of ravines, or low walls. It's not to replace the "Dynamic Lighting" option of blocking movement. That would remain in place, so you would not have both a line on the "Dynamic Lighting" AND on the "Block Movement" layer. I didn't explain myself well and used one example of a use to explain the whole thing. Right now, there are requests for the following enhancements to Dynamic Lighting: Lines that block movement but not sight. Lines that block vision in one direction. Lines that block vision but not movement. Roll20's next improvement to DL lines should at minimum lay the groundwork for all of these requests even if they don't implement them all simultaneously. Implementing #1 by using an additional layer ignores the other requests. Implementing all of the requests as options at the DL line level instead of a new layer allows all of the special kinds of vision and movement combinations to be implemented. This allows situations like: One way glass (#2) Elevation changes like the roof of a house (#2) Windows (#1) Wall of force (#1) Curtains (#3) Opening a door by turning off all the options rather than having to find a place to put it and then closing the door by turning the options back on rather than having to line it up again (or switch the line between layers).
