## Function Documentation

uint8 CalcPercentVehicleFilled | ( | const Vehicle * | v,
|  | StringID * | colour |

bool CanBuildVehicleInfrastructure | ( | VehicleType | type | ) |

Check whether we can build infrastructure for the given vehicle type.

This to disable building stations etc. when you are not allowed/able to have the vehicle type yet.

Parameters:

  | type | the vehicle type to check this for

Returns:
  true if there is any reason why you may build the infrastructure for the given vehicle type

| ) |  |  |

Can this station be used by the given vehicle?

Parameters:

  | st | the station to test for

Returns:
  true if and only if the vehicle can use this station.

void FindVehicleOnPos | ( | TileIndex | tile,
|  | void * | data,
|  | VehicleFromPosProc * | proc |
| ) |  |  |

Find a vehicle from a specific location.

It will call proc for ALL vehicles on the tile and YOU must make SURE that the "best one" is stored in the data value and is ALWAYS the same regardless of the order of the vehicles where proc was called on! When you fail to do this properly you create an almost untraceable DESYNC!

Note:
  The return value of proc will be ignored.

  Use this when you have the intention that all vehicles should be iterated over.

Parameters:

  | tile | The location on the map
  | data | Arbitrary data passed to proc
  | proc | The proc that determines whether a vehicle will be "found".
