Data Structures | |
struct | BridgeSpec |
Struct containing information about a single bridge type. More... | |
Typedefs | |
typedef uint | BridgeType |
Bridge spec number. | |
Enumerations | |
enum | BridgePieces { BRIDGE_PIECE_NORTH = 0 , BRIDGE_PIECE_SOUTH , BRIDGE_PIECE_INNER_NORTH , BRIDGE_PIECE_INNER_SOUTH , BRIDGE_PIECE_MIDDLE_ODD , BRIDGE_PIECE_MIDDLE_EVEN , BRIDGE_PIECE_HEAD , NUM_BRIDGE_PIECES } |
This enum is related to the definition of bridge pieces, which is used to determine the proper sprite table to use while drawing a given bridge part. More... | |

const BridgeSpec * | GetBridgeSpec (BridgeType i) |
Get the specification of a bridge type. | |
void | DrawBridgeMiddle (const TileInfo *ti) |

Variables | |
static const uint | MAX_BRIDGES = 13 |
Maximal number of available bridge specs. | |
constexpr uint | SPRITES_PER_BRIDGE_PIECE = 32 |
Number of sprites there are per bridge piece. | |
