Enemies are moved along navmesh paths without collision, so a wall only stops them if their path stops at it. dpWorld now keeps a list of such walls, each with the collision filter it blocks with, and cuts a path where it first walks into one (a little short of the wall; a mover inside one can walk out). Which objects block comes from data (dpMovementBlockers::BlockingFilter): - navmesh carvers (navmesh_carver in the level config, which the client reads with add_to_navmesh and carver_only) block every mover; - solid objects whose collision group touches enemies and not players (group 18, e.g. "FV - Enemy Blocking Volume", "PR - Pet Blocker") block what that group touches. dpShapeBox gains SegmentEntry, a segment test against the rotated box.
