Variables

static const uint TILE_SIZE = 16
 Tile size in world coordinates.
static const uint TILE_UNIT_MASK = TILE_SIZE - 1
 For masking in/out the inner-tile world coordinate units.
static const uint TILE_PIXELS = 32
 Pixel distance between tile columns/rows in #ZOOM_LVL_BASE.
static const uint TILE_HEIGHT = 8
 Height of a height level in world coordinate AND in pixels in #ZOOM_LVL_BASE.
static const uint MAX_BUILDING_PIXELS = 200
 Maximum height of a building in pixels in #ZOOM_LVL_BASE. (Also applies to "bridge buildings" on the bridge floor.)
static const uint MAX_TILE_HEIGHT = 255
 Maximum allowed tile height.
static const uint MIN_MAX_HEIGHTLEVEL = 15
 Lower bound of maximum allowed heightlevel (in the construction settings)
static const uint DEF_MAX_HEIGHTLEVEL = 30
 Default maximum allowed heightlevel (in the construction settings)
static const uint MAX_MAX_HEIGHTLEVEL = MAX_TILE_HEIGHT
 Upper bound of maximum allowed heightlevel (in the construction settings)
static const uint MIN_SNOWLINE_HEIGHT = 2
 Minimum snowline height.
static const uint DEF_SNOWLINE_HEIGHT = 15
 Default snowline height.
static const uint MAX_SNOWLINE_HEIGHT = (MAX_TILE_HEIGHT - 2)
 Maximum allowed snowline height.
static const TileIndex INVALID_TILE = (TileIndex)-1
 The very nice invalid tile marker.

Enumeration Type Documentation

enum TileType

The different types of tiles.

Each tile belongs to one type, according whatever is build on it.

Note
A railway with a crossing street is marked as MP_ROAD.
Enumerator:
MP_CLEAR 

A tile without any structures, i.e. grass, rocks, farm fields etc.

MP_RAILWAY 

A railway.

MP_ROAD 

A tile with road (or tram tracks)

MP_HOUSE 

A house by a town.

MP_TREES 

Tile got trees.

MP_STATION 

A tile of a station.

MP_WATER 

Water tile.

MP_VOID 

Invisible tiles at the SW and SE border.

MP_INDUSTRY 

Part of an industry.

MP_TUNNELBRIDGE 

Tunnel entry/exit and bridge heads.

MP_OBJECT 

Contains objects such as transmitters and owned land.

enum TropicZone

Additional infos of a tile on a tropic game.

The tropiczone is not modified during gameplay. It mainly affects tree growth. (desert tiles are visible though)

In randomly generated maps: TROPICZONE_DESERT: Generated everywhere, if there is neither water nor mountains (TileHeight >= 4) in a certain distance from the tile. TROPICZONE_RAINFOREST: Generated everywhere, if there is no desert in a certain distance from the tile. TROPICZONE_NORMAL: Everywhere else, i.e. between desert and rainforest and on sea (if you clear the water).

In scenarios: TROPICZONE_NORMAL: Default value. TROPICZONE_DESERT: Placed manually. TROPICZONE_RAINFOREST: Placed if you plant certain rainforest-trees.

Enumerator:
TROPICZONE_NORMAL 

Normal tropiczone.

TROPICZONE_DESERT 

Tile is desert.

TROPICZONE_RAINFOREST 

Rainforest tile.
