CrystalCliff

Tile set holding the crystal cliff pieces.

Specification

Applies to: tile controls
File: theater control file
Section: [General]
Value: integer
When omitted: -1The role stays unresolved, because no tile set number can match it, and crystal ground then counts some cells of the theater's first, fourth and fifth tiles as crystal.

Crystal ground counts some cells of four crystal cliff pieces as crystal. Each piece covers several cells, numbered across each row from 0 at the top left. A neighboring cell counts as crystal when it holds any of:

the set’s first piece, on cell 0 or 1,
the second piece, on cell 2 or above,
the fifth piece, on an even-numbered cell,
the sixth piece, on an odd-numbered cell.

Every other cell of those four pieces, and every cell of the set’s other pieces, counts as foreign. A crystal cell next to a foreign neighbor takes a blend edge from ClearToCrystalLat. Theater control files explains how a [General] role is resolved to a tile.

The random map generator also places pieces of this set, on mutated-biome maps with Firestorm enabled:

A crystal deposit that starts on a cliff face hangs a crystal formation off it, using the set’s first, second, fifth or sixth piece.
When the cliff pass lays a north-west inside corner or a lone north-west outside corner, it has a one-in-twenty chance of laying a crystal cliff piece instead. Six of the forty CliffSet shapes are affected.
