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. | |

| Foundation | GetBridgeFoundation (Slope tileh, Axis axis) |
| Get the foundation for a bridge. | |
| 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) |
| Get the specification of a bridge type. | |
| void | DrawBridgeMiddle (const TileInfo *ti) |
| Draw the middle bits of a bridge. | |
| 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] |
| The specification of all bridges. | |
