< p > Eight attributes (counting " < span style = "font-weight: bold;" > type_height< / span > " ) hold the informations about a tile.< BR >
2007-02-15 22:03:48 +00:00
These attributes are referred to as
2010-08-27 10:42:48 +00:00
" < 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 > " , " < span style = "font-weight: bold;" > m6< / span > "
and "< span style = "font-weight: bold;" > m7< / span > ".< br >
2007-01-23 02:31:49 +00:00
The most important value is the class of a tile, stored in the upper 4 bits
2007-03-01 20:10:49 +00:00
of the < span style = "font-weight: bold;" > type_height< / span > attribute. The lower 4 bits are used to encode the height and
slope data.

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 >
