Methods

AppendDriverDestinations

public void AppendDriverDestinations(string[] destNames, string[] destTracks)

Parameters

• destNames = OUTPUT - An array of localised and human-readable track names. See StringTable.gs for details on how to support localisation.
• destTracks = OUTPUT - An array of machine-readable track names, as specified in the industry asset config file.

Returned Value

• None

Syntax

string[] localisedNames = new string[0];
string[] destinationNames = new string[0];
AppendDriverDestinations(localisedNames, destinationNames);

Notes

• Provides destinations for use of this industry on the Drive To sub-menu.
• If the programmer wants the appropriate destinations to appear in the Drive To command's menus, this method must be implemented.
• A user readable name and the name of the actual destination track must be provided.
• Two arrays are passed in as return arguments, one for the readable names and the other for the track names.
• The indexes of each these arrays must correspond.
• You don't have to worry about allocating memory for the arrays as Trainzscript expands the array size automatically if this is necessary.

AppendDriverDestinations

public void AppendDriverDestinations(Asset product, bool bIsForUnloading, string[] destNames, string[] destTracks)

Parameters

• product = A product asset that the caller wants to load/unload.
• bIsForUnloading = Specifies whether the caller wants deliver/unload the product (true) or pickup/load it (false).
• destNames = OUTPUT - An array of localised and human-readable track names. See StringTable.gs for details on how to support localisation.
• destTracks = OUTPUT - An array of machine-readable track names, as specified in the industry asset config file.

Returned Value

• Whether the function is implemented. This function should only return false if the scripter has not implemented it at all. If the the function is implemented to ever return any destination tracks (for any product), then it should always return true.

Syntax

string[] localisedNames = new string[0];
string[] destinationNames = new string[0];
AppendDriverDestinations(desiredProduct, desiredLoadUnloadAction, localisedNames, destinationNames);

Notes

• Functions as per the original AppendDriverDestinations variant (detailed above), but filters the returned list to a specific product and load/unload action.
• Required to correctly support Living Railroad load/unload at multi-track industries.
