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.

For a graphical representation of the tile-layout have a look at
|
|
<a href="landscape_grid.html">Landscape grid</a> page.
|
|
</p>
|
|
<p>Nine attributes (counting "<span style="font-weight: bold;">type</span>" and
|
|
"<span style="font-weight: bold;">height</span>") hold the information about a tile.<BR>
|
|
These attributes are referred to as
|
|
"<span style="font-weight: bold;">type</span>",
|
|
"<span style="font-weight: bold;">height</span>",
|
|
"<span style="font-weight: bold;">m1</span>", "<span style="font-weight: bold;">m2</span>",
|
|
"<span style="font-weight: bold;">m3</span>", "<span style="font-weight: bold;">m4</span>",
|
|
"<span style="font-weight: bold;">m5</span>", "<span style="font-weight: bold;">m6</span>"
|
|
and "<span style="font-weight: bold;">m7</span>".<br>
|
|
The most important value is the class of a tile, stored in the upper 4 bits
|
|
of the <span style="font-weight: bold;">type</span> attribute.
|
|
</p>
|
|
|
|
Frequently repeating patterns:

<small><a name="newhouses"></a>Newhouses is the name englobing a newGRF feature developed by TTDPatch devs (mainly Csaboka).<br>
|
|
It allows the replacement of the properties as well as the graphics of houses in the game.<br>
|
|
To distinguish between the standard behaviour and the newGRF one, HouseID (m4 + m3[6]) is tested for anything above 110.<br>
|
|
110 is the count of standard houses. So above 110 means there is a new definition of at least one house</small>
