Description

Dike map (0x82)

The variable returns the sides and edges at which the water has a dike, i.e. no connection to water. The variable is a bitset where single bits indicate a dike towards the eight adjacent tiles:

Bit Value Direction
0 1 North-East
1 2 South-East
2 4 South-West
3 8 North-West
4 16 East
5 32 South
6 64 West
7 128 North

Supported by TTDPatch In TTDPatch this variable is for internal use only.
