Line (ID 4, Line) is a built-in terrain. Lines are a generic wall type that use the configured thick lines ID chars (144-159) to determine their display character based on their surroundings.

Behavior

The display character of a Line is derived from the IDs in the four positions immediately surrounding it:

offset = 0

if Line or board edge to the north:
  offset += 1

if Line or board edge to the south:
  offset += 2

if Line or board edge to the east:
  offset += 4

if Line or board edge to the west:
  offset += 8

char = offset + thick lines ID animation start (144)
