This seems like a pretty basic thing to do and I’m probably just doing it wrong.
Ignore the watch node pretending to be a list of walls. I just didn’t want to clutter the snapshot.
The last topic of this name didn’t post anything.
Wall Location is saved a number. the “Wall Location” node is useless for this function. Use a “get parameter” node to see what “Location Line” is stored as, you’ll get it.
