<h3><a name="Landscape">Landscape</a></h3>
|
|
<p>Seven attributes (counting "<span style="font-weight: bold;">type_height</span>") hold the informations about a tile.<BR>
|
|
These attributes are referred to as
|
|
"<span style="font-weight: bold;">type_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>" and "<span style="font-weight: bold;">m6</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_height</span> attribute. The lower 4 bits are used to encode the height and
|
|
slope data.
|
|
</p>
|
|
|
|
Special Attribute : <span style="font-weight: bold;">m6</span>. There are 4 bits of it that are used accross multiple tile classes<br>
|
|

|

For a graphical representation of the tile-layout have a look at

|
|
|
|
The <a name="OwnershipInfo">owner of a tile</a>, as frequently associated with attribute m1,
|
|
can be either players (human or AI) or "Game entities".
|
|
They are identified using:
|
|
<table border="1">
|
|
<tr><td><tt>00</tt> </td><td align=left>current player</td></tr>
|
|

<small><a name="newhouses">Newhouses is the name englobing a newGRF feature developped 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>
