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, BRIDGE_PIECE_INVALID } |
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. | |
Functions | |
Foundation | GetBridgeFoundation (Slope tileh, Axis axis) |
bool | HasBridgeFlatRamp (Slope tileh, Axis axis) |
Determines if the track on a bridge ramp is flat or goes up/down. | |
static const BridgeSpec * | GetBridgeSpec (BridgeType i) |
void | DrawBridgeMiddle (const TileInfo *ti) |
CommandCost | CheckBridgeAvailability (BridgeType bridge_type, uint bridge_len, DoCommandFlag flags=DC_NONE) |
Is a bridge of the specified type and length available? | |
int | CalcBridgeLenCostFactor (int x) |
Calculate the price factor for building a long bridge. | |
void | ResetBridges () |
Reset the data been eventually changed by the grf loaded. | |
Variables | |
static const uint | MAX_BRIDGES = 13 |
Maximal number of available bridge specs. | |
BridgeSpec | _bridge [MAX_BRIDGES] |
static const uint | MAX_BRIDGE_LENGTH = 16 |
Maximum length of the bridge. | |
static const uint | MAX_BRIDGE_LENGTH_LONGBRIDGES = 100 |
Maximum length of the bridge with longbridges enabled. |
