• A vehicle is always part of a train, if a vehicle is decoupled and left alone Trainz will create a new consist to include it.

Related Messages

• Messages sent to and from Vehicle objects are listed below:

Major	Minor	Source	Destination
Vehicle	Derailed	Vehicle	Vehicle	Vehicle has derailed and can no longer be driven.
Vehicle	Coupled	Vehicle	Vehicle (other)	Vehicle has coupled to another Vehicle.
Vehicle	Decoupled	Vehicle	Vehicle (other)	Vehicle has decoupled from another vehicle.
Vehicle	Coupler breakage	Vehicle	Vehicle	Vehicle coupler has broken (likely due to being coupled too fast).
Vehicle	BadCouple	Vehicle	Vehicle (other)	Vehicle has coupled with another vehicle at too high a velocity.
Vehicle	Collided	Vehicle	Vehicle (other)	Vehicle has collided with another vehicle (either a couple was attempted too fast and broke the coupler, or the coupler was already broken).

Constants

Coupler Flags

public define int COUPLE_NONE = 0	Neither coupler.
public define int COUPLE_FRONT = 1	Front coupler.
public define int COUPLE_BACK = 2	Back coupler.
public define int COUPLE_BOTH = COUPLE_FRONT ¦ COUPLE_BACK	Both couplers.

Direction Relationships

public define int DIRECTION_NONE = 0	No known relationship.
public define int DIRECTION_FORWARD = 1	Forward, facing in the same direction.
public define int DIRECTION_BACKWARD = -1	Backward, facing in opposite directions.

Engine Types

public define int ENGINE_NONE = 0	Not a powered vehicle.
public define int ENGINE_STANDARD = 1	Diesel, Diesel-Electric, Electric.
public define int ENGINE_STEAM = 2	Steam powered.

Vehicle Type Flags

public define int TYPE_LOCOMOTIVE = 1	Vehicle is a powered locomotive.
public define int TYPE_TENDER = 2	Vehicle carries fuel for a locomotive.
public define int TYPE_HAS_INTERIOR = 4	Vehicle has an interior. This does not necessarily mean that it is a lcomotive.

Having tested these values with the associated function 'GetVehicleTypeFlags', it seems that the 'Vehicle Type Flag' for a loco is '5' and not '1'
vincentrh

Perhaps they are bit flags?  Therefore a value of 1 (loco) and 4 (has interior) would result in 5 being returned for a loco with an interior.  i.e. 1 and 4 "OR"ed together.

Members

public IndustryProductInfoCollection vehicleProductInfoCollection

A data object that allows tracking of products and associated assets & queues.

Methods

BeginLoad

float BeginLoad(LoadingReport report)

Parameters

• report = Report on the current state of the loading operation.

Returned Value

• The time required, in seconds, for the activity to complete.

Syntax

float BeginLoad(LoadingReport report) {
   DoStuff(report);
   return 10.0;
}

Notes

• This is a callback method which should be overridden by the script writer to perform customised activities before loading at an industry.
• These include such operations as particle effects and animations.
• The report parameter provides details of the industries and vehicles involved and of their spatial relationship.
• It is the responsibility of the script writer to determine the time required for these activities and to return this in the method result.

BeginUnload

float BeginUnload(LoadingReport report)

Parameters

• report = Report on the current state of the loading operation.

Returned Value

• The time required, in seconds, for the activity to complete.

Syntax

float BeginLoad(LoadingReport report) {
   DoStuff(report);
   return 10.0;
}

Notes

• This is a callback method which should be overridden by the script writer to perform customised activities before loading at an industry.
• These include such operations as particle effects and animations.
• The report parameter provides details of the industries and vehicles involved and of their spatial relationship.
• It is the responsibility of the script writer to determine the time required for these activities and to return this in the method result.

CanLoadProductFromQueue

public bool CanLoadProductFromQueue(ProductQueue queue)

Parameters

• queue = The queue to be queried.

Returned Value

• True if the vehicle and queue are compatible and the queue can be used to load the vehicle, false otherwise.
• None

Syntax

if (CanLoadProductFromQueue(industryOutQueue)) {
   DoTheProcess();
}

Notes

CanUnloadProductToQueue

public bool CanUnloadProductToQueue(ProductQueue queue)

Parameters

• queue = The queue to be queried.

Returned Value

• True if the vehicle and queue are compatible and the queue can be used to unload the vehicle, false otherwise.

Syntax

if (CanUnloadProductToQueue(industryOutQueue)) {

Notes

Couple

public native bool Couple(Vehicle other)

Parameters

• other = Adjacent vehicle to couple to.

Returned Value

• True if the operation was successful, fale otherwise.

Syntax

if (Couple(vehicle2)) Interface.Print("Success!");

Notes

• If the two vehicles involved are not adjacent then this method will have no effect.
• When a vehicle is decoupled from another, the couplers are left in an unlocked state, even though the vehicles are flush against each other. This state will remain until the vehicles move some distance apart, or the coupler is relocked using this function.
• Coupling two vehicles will merge their Train objects, resulting in one of the trains being deleted. (ie, GetMyTrain() may return a different result after calling this function.) It is not safe for script to predict which Train will be kept, so any cached Train references should be released.

EndLoad

float EndLoad(LoadingReport report)

Parameters

• report = Report on the current state of the loading operation.

Returned Value

• The time required, in seconds, for the activity to complete.

Syntax

float EndLoad(LoadingReport report) {
   DoStuff(report);
   return 10.0;
}

Notes

• This is a callback method which should be overridden by the script writer to perform customised activities after loading at an industry.
• These include such operations as particle effects and animations.
• The report parameter provides details of the industries and vehicles involved and of their spatial relationship.

Notes

• Loads products into this vehicle as defined by the given report.
• This method works by attempting to transfer products to this vehicle's queues if possible from the industry queue specified in report.
• The sequence of events for a loading operation as performed by this method is:
  • Verify that an loading operation is possible with this vehicle by calling CanLoadProductFromQueue().
  • BeginLoad() on this vehicle and Industry.BeginLoad() on the industry specified in the report are called to perform any pre-loading events like animation or particle effects on the vehicle and industry respectively.
  • Both of these methods return the amount of time required for a load operation and the LoadProduct() method sleeps for which ever of these times is the longer.
  • The actual product transfer from the industry to the vehicle is performed by calling ProductQueue.TransferProductFrom() on this vehicle's queue(s).
  • GetLoadTime() on this vehicle and Industry.GetLoadTime() are called. Again, LoadProduct() sleeps for which ever is the longer of the times returned.

Notes

• Despite the name, the passed value is a speed (ie. unsigned, ie. must be greater than or equal to 0).
• If coupler breakage is enabled, then a coupling attempt above this speed will break the coupler, and post a "Coupler breakage" message, followed by a "Collided" message.
• If coupler breakage is not enabled, hen a coupling attempt above this speed will fail, and post a "BadCouple" message.
• Passing a value of 0.0/zero can be used allow coupling to happen any speed.

Parameters

• product = Asset to which this vehicle's load is to be restricted.

Returned Value

• True if successful, false otherwise.

Syntax

SetProductRestriction(coal);

Notes

• Restricts this vehicle to only allow the given product.
• When a product restriction is in effect, only that product may be either loaded or unloaded.
• This method overrides any previous call to SetProductDisabled().
• If the product parameter is null, any product compatible with this vehicle can be loaded/unloaded.
• If it is a product that is not compatible with this vehicle, no restriction is set and false will be returned.

SetQueueInitialCount

public void SetQueueInitialCount(ProductQueue queue, Asset product, int amount)

Parameters

• queue = Queue to use, any existing products in this queue will be destroyed.
• product = Asset of product to use.
• amount = Amount of product to use.

Returned Value

• None

Syntax

SetQueueInitialCount(passengerQueue,passengers,20);

Notes

• Fills the given queue with the specified quantity of product.
• This method sets the amount of products in the given queue.
• It is a utility method that works on the given queue which need not be a queue from this vehicle.
• The product filter provided with queue will be used to check if the queue can take products of type asset.
• If it can't, the filter will be modified to suit as this method is forceful in that regard.

SetRollBasedOnTrack

public native void SetRollBasedOnTrack(float multiplier)

Parameters

• multiplier = The value to multiply the curve by to get the train roll angle.

Returned Value

• None

Syntax

SetRollBasedOnTrack(2.0);

Notes

• This feature is often used by "non-train" vehicles like aeroplanes or boats.
• Pitch is the left/right rotation of the vehicle mesh (ie, roation about an axis parallel to the track direction).
• Use a positive value to lean 'into' the curve, a negative value to lean out.

SetRunningNumber

public native void SetRunningNumber(string number)

Parameters

• number = The running (fleet identification) number of the vehicle.

Returned Value

• None

Syntax

SetRunningNumber("21C1");
SetRunningNumber("4472");

Notes

• This value is retrieved using GetRunningNumber() and should be restricted to alphanumeric characters and spaces.

SetSandingTractionMultiplier

public native void SetSandingTractionMultiplier(float factor)

Parameters

• factor = A multiplier value of 1.0 or more defining the increase in this vehicle's tractive effort when sand is in use.

Returned Value

• None

Syntax

SetSandingTractionMultiplier(1.5); // allow sanding to increase tractive effort by 50%

Notes

SetWheelslipTractionMultiplier

public native void SetWheelslipTractionMultiplier(float factor)

Parameters

• factor = A multiplier value of 1.0 or less to apply to decrease this vehicle's traction when wheelslip occurs.

Returned Value

• None

Syntax

SetWheelslipTractionMultiplier(0.25); // wheelslip reduces tractive effort to 25% of normal.

Notes

• A multiplier value of 1.0 disables the wheelspin sound.

Uncouple

public native void Uncouple(int direction)
public native void Uncouple(Vehicle other)

Parameters

• direction = A Coupler Flags constant indicating which coupler to detach.
• other = A reference to the other vehicle form which the caller is to be uncoupled.

Returned Value

• None

Syntax

Uncouple(COUPLE_FRONT);       // uncouple anything that's attached to the vehicle's front coupler
Uncouple(vehicle1);           // uncouple from the specified vehicle

Notes

• Uncoupling will cause another Train object to be created for one half of the train.
• Caling Uncouple(COUPLE_BOTH) is not valid, you must specify a single coupler.
• See also Vehicle.GetCouplingDirection().

UnloadProduct

public bool UnloadProduct(LoadingReport report)

Parameters

• report = Report on the current state of the loading operation.

Returned Value

• True if the unloading operation was successful, false otherwise.

Syntax

UnloadProduct(report);

Notes

• Unloads products into this vehicle as defined by the given report.
• This method works by attempting to transfer products from this vehicle's queues to the industry queue specified in report.
• The sequence of events for an unloading operation as performed by this method is:
  • Verify that an unloading operation is possible with this vehicle by calling CanUnloadProductToQueue().
  • BeginUnload() on this vehicle and Industry.BeginUnload() on the industry specified in the report are called to perform any pre-unloading events like animation or particle effects on the vehicle and industry respectively.
  • Both of these methods return the amount of time required for an unloading operation and the UnloadProduct() method sleeps for which ever of these times is the longer.
  • The actual product transfer to the industry from the vehicle is performed by calling ProductQueue.TransferProductFrom() on the industry queue(s).
  • GetUnloadTime() on this vehicle and Industry.GetUnloadTime() are called. Again, UnloadProduct() sleeps for which ever is the longer of the times returned.
  • EndUnload() and Industry.EndUnload() are called to perform any post-loading events. As before UnloadProduct() sleeps for the longer time.

UpdateViewDetails

void UpdateViewDetails(Message msg)

Parameters

• msg = Message object which triggers this handler.

Returned Value

• None

Notes

• Update the view details window for this vehicle (from the train).
• This method is setup by Init() as a handler method for a message of type "Vehicle","LoadComplete".
• Such a message indicates that the load or queue of the vehicle have changed and the view details window of the train will need to be updated.

ViewDetails

void ViewDetails(Message msg)

Parameters

• msg = Message object which triggers this handler.

Returned Value

• None

Notes

• View details window for this vehicle using the Train's output.
• This method is setup by Init() as a handler method for a message of type "MapObject","ViewDetails".object.
• Such a message indicates that the user has opened the right-click menu of the vehicle and selected the "View Details" menu item.
• This method will call the ViewDetails() method of this vehicle's train so that a Browser window describing the entire train can be displayed to the user.

ViewSchedule

void ViewSchedule(Message msg)

Parameters

• msg = Message object which triggers this handler.

Returned Value

• None

Notes

• View the schedule window for this vehicle from the train.
• This method is setup by Init() as a handler method for a message of type "MapObject","View-Schedule".
• Such a message indicates that the schedule of the vehicle or train is to be displayed for the user.
• This method calls through to Train.UpdateScheduleWindow().

NotifyTrainChanged

public void NotifyTrainChanged(Train prevTrain, Train nextTrain)

Parameters

• prevTrain = The train to which this Vehicle was previously attached.
• nextTrain = The train to which this Vehicle is now attached.

Returned Value

• None

Notes

• In TS12 and greater only.
• Override this function as required, but don't forget to call the inherited version in case it does something in the future.
• Attempting to manipulate the makeup or positioning of any Train from within this function is illegal behavior. If you need to do that, trigger a delayed action using a message or a thread.
