< p > Seven attributes (counting " type_height" ) hold the informations about a tile.< BR >
These attributes are referred to as
"< span style = "font-weight: bold;" > type_height< / span > ",
2007-01-23 02:31:49 +00:00
"< 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 > ",
2007-02-15 22:03:48 +00:00
"< span style = "font-weight: bold;" > m5< / span > " and "< span style = "font-weight: bold;" > m6< / 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
of the type_height array. The lower 4 bits are used to encode the height and

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

Tile animation is started (m4 zeroed) on the periodic processing.< br >
While the animation is in progress, m4 holds the number
of animation cycles that have already taken place.< br >
when this number reaches 8 the animation is stopped.
