These are examples of solutions for common and simple obsolete Trainzscript functions. This is not an exhaustive list. Solutions for more complex obsolete functions can be found (TBD).

class Train

GetVelocity()

GetVelocity obsolete error or warning: <kuid:0000:0000> : VE267: somescript.gs(299) : function GetVelocity is obsolete in object Train.

Repair

You have two replacement options in the Train class (train.gs):

float GetSmoothedVelocity(void);

This function return the train's velocity in metres per second and is suitable for human viewing such as a cab display.

float GetTrainVelocity(void);

This function provides the instantaneous velocity for vehicles in this train, which is good for physics calculations but not good for human-readable display.

Usage example:

float mySpeed;
mySpeed = GetSmoothedVelocity();  // this is the more likely option but depends on what the overall script is trying to do.

// or the more accurate version
mySpeed = GetTrainVelocity();

class Vehicle

GetFacingRelativeToTrain()

???GetFacingRelativeToTrain obsolete error or warning: <kuid:0000:0000> : VE267: somescript.gs(450) : function GetFacingRelativeToTrain is obsolete in object Vehicle.

Repair

You have one replacement option in the Vehicle class (vehicle.gs):

bool GetDirectionRelativeToTrain(void);

This function returns true if the vehicle faces the same way as the Train, false otherwise. This function is a bit tricky to understand and especially when a vehicle, such as a coach/carriage, is involved.

Usage example1:

Vehicle myVehicle;
bool sameDirectionAsTrain;

sameDirectionAsTrain = GetDirectionRelativeToTrain();  

Usage example2:

Vehicle[] trainVehicles;
Vehicle myVehicle;
bool sameDirectionAsTrain;
int i;

trainVehicles = GetMyTrain().GetVehicles();

if (trainVehicles) {  //unlikely to be null but ...

  for (i = 0; i < trainVehicles.size(); ++i) {
    //get direction of this vehicle in the train
    sameDirectionAsTrain = trainVehicles[i].GetDirectionRelativeToTrain();
    if (sameDirectionAsTrain) {
      // do what is necessary here
      Interface.Print("Vehicle "+ (i+1) + " is facing forward");  // add 1 so that the first vehicle is number 1 and not 0 (zero)
    } else {
      Interface.Print("Vehicle "+ (i+1) + " is facing backwards"); 
    }
  }

}
