<h3><a name="Landscape">Landscape</a></h3>

			




	
	
	
		
 
<p>

			




	
	
	
		
 
Five attributes hold the information about a tile.

			




	
	
	
		
 
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>" and

			




	
	
	
		
 
  "<span style="font-weight: bold;">m5</span>".

			




	
	
	
		
 
The most important value is the class of a tile, stored in the upper 4 bits of the type_height array.

			




	
	
	
		
 
The lower 4 bits are used to encode the height and slope data.

			




	
	
	
		
 
For a graphical represenation of the tile-layout have a look at <a href="landscape_grid.html">Landscape grid</a> page.

OTTD's class-specific periodic tile processing routine is called once every +256 ticks for each tile.

<p> Seven attributes (counting &quot;type_height&quot;) hold the informations

			




	
	
	
		
 
  about a tile. 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>".
