Thick Web (ID 19, ThickWeb) is a built-in terrain. It is a generic floor type with the default color 7 and uses the configured thick lines ID chars (144-159) to determine its display character based on its surroundings. It is similar to Web, which uses thin lines instead.

If the board option Fire burns fakes is enabled, Fire can spread onto any Thick Web.

Spiders can be configured to move exclusively on Web types.

Behavior

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

offset = 0

if board edge or anything but Space to the north:
  offset += 1

if board edge or anything but Space to the south:
  offset += 2

if board edge or anything but Space to the east:
  offset += 4

if board edge or anything but Space to the west:
  offset += 8

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