void ShowBuildBridgeWindow | ( | TileIndex | start,
|  | TileIndex | end,
|  | TransportType | transport_type,
|  | byte | road_rail_type |
| ) |  |  |

Prepare the data for the build a bridge window.

If we can't build a bridge under the given conditions show an error message.

Parameters:

  | start | The start tile of the bridge
  | end | The end tile of the bridge
  | transport_type | The transport type
  | road_rail_type | The road/rail type

void ShowErrorMessage | ( | StringID | summary_msg,
|  | StringID | detailed_msg,
|  | int | x,
|  | int | y,
|  | bool | no_timeout |
| ) |  |  |

Display an error message in a window.

Parameters:

  | summary_msg | General error message showed in first line. Must be valid.
  | detailed_msg | Detailed error message showed in second line. Can be INVALID_STRING_ID.
  | x | World X position (TileVirtX) of the error location. Set both x and y to 0 to just center the message when there is no related error tile.
  | y | World Y position (TileVirtY) of the error location. Set both x and y to 0 to just center the message when there is no related error tile.
  | no_timeout | Set to true, if the message is that important that it should not close automatically after some time.
