Landscape

KUDr@6254:

Seven attributes (counting "type_height") hold the informations about a tile.
KUDr@6254: These attributes are referred to as KUDr@6254: "type_height", belugas@6054: "m1", "m2", belugas@6054: "m3", "m4", KUDr@6254: "m5" and "m6".
belugas@6054: The most important value is the class of a tile, stored in the upper 4 bits belugas@6054: of the type_height array. The lower 4 bits are used to encode the height and KUDr@6254: slope data.
KUDr@6254: For a graphical representation of the tile-layout have a look at KUDr@6254: Landscape grid page. KUDr@6254:

The owner of a tile, as frequently associated with attribute m1, KUDr@6254: can be either players (human or AI) or "Game entities". KUDr@6254: They are identified using: KUDr@6254: KUDr@6254: KUDr@6254: KUDr@6254: KUDr@6254: KUDr@6254: KUDr@6254: KUDr@6254:

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