Landscape

belugas@6510:

Seven attributes (counting "type_height") hold the informations about a tile.
belugas@6355: These attributes are referred to as belugas@6355: "type_height", belugas@6054: "m1", "m2", belugas@6054: "m3", "m4", belugas@6355: "m5" and "m6".
belugas@6054: The most important value is the class of a tile, stored in the upper 4 bits belugas@6510: of the type_height attribute. The lower 4 bits are used to encode the height and belugas@6510: slope data. belugas@6510:

belugas@6510: belugas@6510: Special Attribute : m6. There are 4 bits of it that are used accross multiple tile classes
