Landscape

belugas@6184:

Seven attributes (counting "type_height") hold the informations about a tile.
belugas@6029: These attributes are referred to as belugas@6029: "type_height", belugas@5803: "m1", "m2", belugas@5803: "m3", "m4", belugas@6029: "m5" and "m6".
belugas@5803: The most important value is the class of a tile, stored in the upper 4 bits belugas@6184: of the type_height attribute. The lower 4 bits are used to encode the height and belugas@6184: slope data. belugas@6184:

belugas@6184: belugas@6184: Special Attribute : m6. There are 4 bits of it that are used accross multiple tile classes

pasky@464: belugas@6180: The owner of a tile, as frequently associated with attribute m1, belugas@6029: can be either players (human or AI) or "Game entities". belugas@6029: They are identified using: belugas@6184: belugas@6029: belugas@6029: belugas@6029: belugas@6029: belugas@6029: belugas@6029: belugas@6180:
