This stores three flags in unused map bits, and avoids having to look up station graphics and custom station specs to determine blocked/wires/pylons status. This potentially affects rail pathfinding performance. Savegame version is not bumped, as the flags can just be updated every time.

<span style="font-weight: bold;"></span>Nine attributes hold the information about a tile.
|
|
This can be seen in the <a href="landscape.html">Landscape</a> 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.
|
|
|
|
<ul>
|
|
<li><span style="font-weight: bold;">type</span> - 8 bits in size, tile class (bits 4..7), bridge (bits 2..3) tropic zone (bits 0..1, only valid in tropic climate)</li>
|
|
<li><span style="font-weight: bold;">height</span> - 8 bits in size, stores tile height</li>
|
|
<li><span style="font-weight: bold;">m1</span> - 8 bits in size, used to identify the owner of that tile (eg piece of rail, bridge, etc.)</li>
|
|
<li><span style="font-weight: bold;">m2</span> - 16 bits in size, used to identify the index of the given tile (object) in the (object-)array</li>
|
|
<li><span style="font-weight: bold;">m3</span> - 8 bits in size, is used for general storage</li>
|
