### Landscape

Five attributes hold the information about a tile. This can be seen in the Landscape document. This page tries to give an overview of used and free bits of the array so you can quickly see what is used and what is not.

- O - bit is free
- X - bit is used
- - bit of attribute is abused for different purposes

- type_height - 8 bits in size, stores tile height (lower 4 bits) and tile class (upper 4 bits)
- m1 - 8 bits in size, used to identify the owner of that tile (eg piece of rail, bridge, etc.)
- m2 - 16 bits in size, used to identify the index of the given tile (object) in the (object-)array
- m3 - 8 bits in size, is used for general storage
- m4 - 8 bits in size, is used for general storage
- m5 - 8 bits in size, is used for general storage
