Class TrainUtil

• API Hierarchy
  • TrainUtil

• TrainUtil is a static utility class containing a miscellany of methods.
• TrainUtil is located in common.gs.

AlreadyThereStr

public bool AlreadyThereStr(string[ ] target, string search)

Parameters

• target = Array of strings to search.
• search = String to look for.

Returned Value

• Boolean indicating whether or not the string search exists in the target array.

Syntax

string[] target = Str.Tokens("one two three");
bool found = TrainUtil.AlreadyThereStr(target,"four");    // the result will be false

Notes

• As is usual in Trainzscript string methods the search is case sensitive.

AreInTrain

public bool AreInTrain(Train train, Vehicle[ ] vehicles)

Parameters

• train = Train to search.
• vehicles = Array of vehicle to look for.

Returned Value

• True if all of the vehicles in the array are found in the train, false otherwise.

Syntax

bool allPresent = TrainUtil.AreInTrain(train,vehicles);

Notes

• See also IsInTrain()

CompareStrLists

public bool CompareStrLists(string[ ] list1, string[ ] list2)

Parameters

• list1,list2 = String arrays.

Returned Value

• True if the lists are identical, same strings in each index position, same total count. False otherwise.

Syntax

bool identical = TrainUtil.CompareStrLists(address1,address2);

Notes

CreateTrainFromSoup

public Train CreateTrainFromSoup(Soup trainSoup, string trackmarkName, bool direction)

Parameters

• trainSoup = Consist definition in the form returned by World.GetSurveyorSavedConsist().
• trackmarkName = Name of the trackmark where the train is to be placed.
• direction = True denotes that the train direction should match that of the trackmark.

Returned Value

• A reference to the newly created train if successful, null otherwise.

Syntax

Train train = TrainUtil.CreateTrainFromSoup(BrightonBelle,"Victoria Station",true);

Notes

• It is the script programmer's responibility to ensure that sufficient track exists.
• See also World.CreateTrain().

DoCoupleUp

public Train DoCoupleUp(Train train, Train coupleTo)

• train = First train.
• coupleTo = Train to couple with.

Returned Value

• A reference to the newly extended train.

Syntax

Train newTrain = TrainUtil.DoCoupleUp(train, newSection);

Notes

DoDecouple

public Train DoDecouple(Train train, int count)

Parameters

• train = Train reference.
• count = Number of wagons to detach from the rear of the train.

Returned Value

• A reference to the remaining consist (front section) if successful, null otherwise.

Syntax

train = TrainUtil.DoDecouple(train,4);  // drop four cars from the rear of the train, train will be null if this fails.

Notes

• It is assumed that the train is stopped and already in position.
• The method will wait for the operation to be completed.

GetAfter

public string GetAfter(string target, string search)

Parameters

• target = String to operate on.
• search = String containing delimiter characters.

Returned Value

• Substring of target to the right of the characters in search.

Syntax

string result = TrainUtil.GetAfter("Afternoon", "er");   // result is "noon"

Notes

• The method starts at the end of the string and works backwards until any of the characters in search are encountered.
• Once any character in search is found the substring after that character is returned.
• If search is not found the result will be an empty string.

GetUpTo

public string GetUpTo(string target, string search)

Parameters

• target = String to operate on.
• search = String containing delimiter characters.

Returned Value

• Substring of target to the left of the characters in search.

Syntax

string result = TrainUtil.GetUpTo("Before noon"," no");   // result is "Before"

Notes

• The method starts at the beginning of the string and works forwards until any of the characters in search are encountered.
• Once any character in search is found the substring before that character is returned.
• If search is not found the result will be an empty string.

HasPrefix

public bool HasPrefix(string target, string prefix)

Parameters

• target = String to operate on.
• prefix = String containing prefix to search for.

Returned Value

• True if target starts with prefix, false otherwise.

Syntax

bool IsPrefixed = TrainUtil.HasPrefix("ante","antecedent"); // returns true

Notes

HasSufix

public bool HasSufix(string target, string suffix)

Parameters

• target = String to operate on.
• suffix = String containing suffix to search for.

Returned Value

• True if target ends with suffix, false otherwise.

Syntax

bool IsSuffixed = TrainUtil.HasSufix("dent","antecedent"); // returns true

Notes

• This will not work if the method identifier is correctly spelled!

IsInTrain

public bool IsInTrain(Train train, Vehicle vehicle)

Parameters

• train = Train reference.
• vehicle = Vehicle reference.

Returned Value

• True if vehicle is included in train, false otherwise.

Syntax

bool brakeVanPresent = TrainUtil.IsInTrain(train,brakeVan); 

Notes

• See also AreInTrain()

IsPartTrainInTrigger

public bool IsPartTrainInTrigger(GameObject runningThread, Train train, Trigger trigger)

Parameters

• runningThread = Thread that called this method.
• train = Reference to a train.
• trigger = Reference to the trigger to query.

Returned Value

• True if any part of the train is in the trigger area, false otherwise.

Syntax

bool arrived = TrainUtil.IsPartTrainInTrigger(me,train,trigger);

Notes

IsTrainInTrigger

public bool IsTrainInTrigger(GameObject runningThread, Train train, Trigger trigger)

Parameters

• runningThread = Thread that called this method.
• train = Reference to a train.
• trigger = Reference to the trigger to query.

Returned Value

• True if the train is in the trigger area, false otherwise.

Syntax

bool arrived = TrainUtil.IsTrainInTrigger(me,train,trigger);

Notes

RandBool

public bool RandBool(void)

Parameters

• None

Returned Value

• True or false at random.

Syntax

if(TrainUtil.RandBool()) DoItAtRandom();

Notes

RunTurnTable

Is this still valid?

public void RunTurnTable(GameObject runningThread, Train train, string turntable)

• runningThread = Thread that called this method.
• train = Reference to a train.
• turntable = Name of turntable.

Returned Value

• None

Syntax

TrainUtil.RunTurnTable(me,train,"Turntabel 1");

Notes

• ???????

StrSubst

public string StrSubst(string target, string remove, string replace)

Parameters

• target = String to operate on.
• remove = Substring to remove.
• replace = Replacement substring.

Returned Value

• Returns the string target with replace substituted for remove, if the method fails an empty string is returned.

• remove must exist as a substring of target, otherwise and empty string will be returned.
• remove and replace do not have to be the same length.
• Only the first instance of remove will be substituted.

WaitUntilHas

Is this still valid?

public void WaitUntilHas(Vehicle loco, ShuntTrack tracking)

Parameters
