<td>Session rules can be arranged in a hierarchical fashion, in a series of levels as shown in the example on the left. A '''Parent Rule''' can be used to group together a set of rules at a lower level in the hierarchy. The rules that are grouped together under a '''Parent Rule''' are the '''Child Rules'''.<br><br>
  
In the screenshot above, the
+
'''Child Rules''' can also be '''Parent Rules''' that group together other rules at an even lower level. This creates multiple levels in the hierarchy.<br><br>
*'''Trigger Check Rule''' is a Parent Rule. It has rules indented below it.
+
**'''Simultaneous List Rule''' is indented under the '''Trigger Check Rule''' so it is a Child of that rule. It is also a Parent Rule as it has rules indented below it

***'''Message Popup Rule''' is indented under the '''Simultaneous List Rule''' so it is a Child of that rule.

****'''Close Message Popup Rule''' is indented under the '''Wait Rule''' so it is a Child of that rule.  
+
  
You can think of this as a family tree.
+
The '''Parent Rule''' at the head of each level in the hierarchy acts as a ''switch'' that directs the Trainz session to either ignore (skip over) or obey (execute) the '''Child Rules''' under its control.<br>

==Parent/Child Rule Example==
 +
In the following example, a '''Trigger Check Rule''' is acting as the ''switch'' that decides whether or not its child rules will be executed. If the Trigger is activated, for example by a particular train passing over its track trigger, then its child rules will be executed. Otherwise the '''Trigger Check Rule''' will wait indefinitely until that event occurs, or the session is terminated.

The information in this Wiki Page applies to TANE, TRS19, Trainz Plus and TRS22.

Contents

BlueDot10x10.png Session Rules are the "programming tools" for constructing interactive sessions
BlueDot10x10.png Parent Rules are the decision makers amongst the Session Rules
  Top   Next Down Bottom

[edit] What Are Parent and Child Rules?

BlueDot10x10.png Rules that act as Parent Rules can have one or more sub-rules or Child Rules under them
BlueDot10x10.png Rules are edited and managed by the Session Editor in Surveyor


LinkWiki.PNG

More information on the Session Editor can be found on the Trainz Wiki Page at:-


Most Parent Rules are used as "decision makers" in Trainz Sessions. They decide if or when other rules, the Child Rules, will be executed. Some Parent Rules control how those Child Rules are executed.
NotePad.PNG Notes:
DotPoint.JPG Only certain rules can be Parent Rules. See the Trainz Wiki page WikiLink.PNG List of Parent Rules for details
DotPoint.JPG Most Parent Rules will either wait for a specific event or perform a test or a comparison. They will execute their Child Rules when the event occurs or the test/comparison is true
DotPoint.JPG Any rule can be a Child Rule including other Parent Rules


Parent Child.PNG Session rules can be arranged in a hierarchical fashion, in a series of levels as shown in the example on the left. A Parent Rule can be used to group together a set of rules at a lower level in the hierarchy. The rules that are grouped together under a Parent Rule are the Child Rules.

Child Rules can also be Parent Rules that group together other rules at an even lower level. This creates multiple levels in the hierarchy.

The Parent Rule at the head of each level in the hierarchy acts as a switch that directs the Trainz session to either ignore (skip over) or obey (execute) the Child Rules under its control.


BlueDot10x10.png Rules that act as Child Rules are indented under a Parent Rule


SessionRuleIndent.JPG
Steps: To indent a rule:-
DotPoint1.JPG select (Left Click) the rule to be indented
DotPoint2.JPG Left Click the Right Arrow Indent tool at the bottom of the Session Editor

[edit] Parent/Child Rule Example

In the following example, a Trigger Check Rule is acting as the switch that decides whether or not its child rules will be executed. If the Trigger is activated, for example by a particular train passing over its track trigger, then its child rules will be executed. Otherwise the Trigger Check Rule will wait indefinitely until that event occurs, or the session is terminated.

Message Popup.jpg
DotPoint.JPG the cause of the trigger event is set in the properties of the Trigger Check Rule
DotPoint.JPG the message shown is set in the properties of the Message Popup Rule
DotPoint.JPG the duration of the wait is set in the properties of the Wait Rule
In the screenshot above, the
Line  1 : Trigger Check Rule is a Parent Rule. It has rules indented below it which are its Child Rules:-
Line  2 : Simultaneous List Rule is indented under the Trigger Check Rule so it is a Child of that rule. It is also a Parent Rule and it has its own Child Rules indented below it:-
Line  3 : Message Popup Rule is indented under the Simultaneous List Rule so it is a Child of that rule
Line  4 : Wait Rule is indented under the Simultaneous List Rule so it is a Child of that rule. It is also a Parent Rule as it has rules indented below it
Line  5 : Close Message Popup Rule is indented under the Wait Rule so it is a Child of that rule


Sequence of Events
DotPoint1.JPG When the consist identified in the Trigger Check Rule, a Parent Rule, reaches the set trigger, the Trigger Event is activated and its Child Rules are executed
DotPoint2.JPG The Simultaneous List Rule, a Parent Rule, is then executed. It executes all its Child Rules immediately and simultaneously
Simultaneously...
DotPoint3.JPG The Message Popup Rule is executed
DotPoint3.JPG The Wait Rule is executed. This is set to force a 20 second wait, then ...
DotPoint4.JPG The Close Message Popup Rule is executed. This closes the Message window created by the Message Popup Rule
DotPoint5.JPG Since the Close Message Popup Rule is the last child rule under the Wait Rule, when it has completed its task (closing the message popup) it will terminate the Wait Parent Rule
DotPoint6.JPG Since it is also the last child rule under the Simultaneous List Rule it will terminate that Parent Rule
DotPoint7.JPG Finally, since it is the last child rule under the Trigger Check Rule, it also terminates that Parent Rule

[edit] Ordered Lists vs Simultaneous Lists

The majority of sibling Child Rules, rules that are at the same indent level under a Parent Rule, will be executed in order (an Ordered List) or simultaneously (a Simultaneous List).

[edit] Ordered Lists

BlueDot10x10.png Details for this rule can be found at WikiLink.PNG Ordered List Rule
BlueDot10x10.png Ordered Lists are shown with numbered icons on each Child Rule which indicates the order in which they will be executed


OrderedListRule.JPG
NotePad.PNG Notes:

DotPoint.JPG an Ordered List can be set to repeat a set number of times
DotPoint.JPG each Child Rule in the sequence must be completed before the next Child Rule can be executed
DotPoint.JPG an Ordered List is completed when the last Child Rule is completed


PencilTips.PNG Because some rules will wait for an event (such as a mouse click, a set time or a time period, a trigger, etc) before they are completed, it is possible for the Ordered List to hang indefinitely waiting for the event to occur. This will stop that particular Child Rule from being completed and any following Child Rules from being started. So, if possible, place Child Rules that are event dependent at the end of an ordered list.


 Setting the Options 

The rule settings allow you to control how many times an Ordered List will run.

Steps: To set the repeat options for an Ordered List:-
DotPoint1.JPG select (Left Click on) the Ordered List in the Session Editor
DotPoint2.JPG select (Left Click on) the  Edit  button at the bottom of the Session Editor to open the Ordered List properties window
DotPoint3.JPG Select an Option Button:-
BlueDot10x10.png This process will repeat 1 time(s)
BlueDot10x10.png This process will repeat forever
DotPoint4.JPG to change the number of repeats to any required number Left Click on the 1 and enter a new value. Click the Link= to accept the change
DotPoint5.JPG to accept the new rule settings Left Click on the Link= or the  Save Changes  button (depending on your version of Trainz) in the rule properties window

RuleRepeatsEntry.png


NotePad.PNG Notes:

DotPoint.JPG the minimum number is 1 which means that the Ordered List will execute once only
DotPoint.JPG the "repeat forever" option will force the list to restart again endlessly


[edit] Simultaneous Lists

BlueDot10x10.png Details for this rule can be found at WikiLink.PNG Simultaneous List Rule
BlueDot10x10.png Simultaneous Lists are shown with equality (=) icons on each Child Rule which indicates that they will all be executed at the same time


SimultaneousListRule.JPG
NotePad.PNG Notes:

DotPoint.JPG a Simultaneous List can be set to complete when all the Child Rules have been completed, or when any one of the Child Rules has been completed
DotPoint.JPG while all Child Rules in a Simultaneous List will start at the same time, some will take longer to complete than others and some may wait for a particular event before they can complete


 Setting the Options 

The rule settings allow you to control how a Simultaneous List will be terminated.

Steps: To set the "completion" options for a Simultaneous List:-
DotPoint1.JPG select (Left Click on) the Simultaneous List in the Session Editor
DotPoint2.JPG select (Left Click on) the  Edit  button at the bottom of the Session Editor to open the Simultaneous List properties window
Depending on your version of Trainz 2 or 3 options are presented by cycling ("clicking") through the underlined text.
DotPoint3.JPG Select an option:-
BlueDot10x10.png all child rules have reached a completed state
BlueDot10x10.png all child rules have reached a 'was completed' state
BlueDot10x10.png one of the child rules has completed
DotPoint4.JPG to accept the new rule settings Left Click on the Link= or the  Save Changes  button (depending on your version of Trainz) in the rule properties window
RuleAllCompletedSetting.png

RuleWasCompletedSetting.png

RuleOneCompletedSetting.png


NotePad.PNG Notes:

DotPoint.JPG the first option, "all child rules have reached a completed state", means that the Simultaneous List will wait until ALL child rules have been completed before terminating. Some child rules may wait for an event, such as a trigger or a set time, before they terminate
DotPoint.JPG the second option, "all child rules have reached a 'was completed' state", is needed for the UDS feature in TRS19 Platinium and later versions that allows you to switch between Driver and Surveyor. If you make the switch back to Driver when some rules have been completed but others have not, then the completed child rules will not be restarted and the Simultaneous Rule will wait until all the child rules reach the was completed state before it terminates
DotPoint.JPG the third option, "one of the child rules has completed" will terminate the Simultaneous Rule, and any child rules that have not yet completed, as soon as one child rule completes

[edit] Progressive Lists

BlueDot10x10.png Details for this rule can be found at WikiLink.PNG Progressive List Rule
BlueDot10x10.png Progressive Lists are shown with numbered icons on each Child Rule which indicates the progressive order in which they will be executed on each cycle of the list


ProgressiveListRules.JPG
NotePad.PNG Notes:

DotPoint.JPG a Progressive List executes only a single child rule each time it runs
DotPoint.JPG on the first run of a Progressive List, only the first Child Rule is executed. On the second run, the second Child Rule is executed. On the third run the third Child Rule is executed, etc. Until all the child rules have been executed


 Setting the Options 

The rule settings allow you to control what happens after the last child rule in a Progressive List has been completed.

Steps: To set the "completion" options for a Progressive List:-
DotPoint1.JPG select (Left Click on) the Progressive List in the Session Editor
DotPoint2.JPG select (Left Click on) the  Edit  button at the bottom of the Session Editor to open the Progressive List properties window
You can select from 3 options by cycling ("clicking") through the underlined text.
DotPoint3.JPG Select an option:-
BlueDot10x10.png ... successive runs will do nothing - after the last child rule has been completed the Progressive Rule will terminate
BlueDot10x10.png ... last child .... will be used for all successive runs - after the last child rule has been completed the Progressive Rule will repeat that child rule on all further runs
BlueDot10x10.png ... the first child is chosen again - after the last child rule has been completed the Progressive Rule will start with the first child rule again and it will repeat the sequence
DotPoint4.JPG to accept the new rule settings Left Click on the Link= or the  Save Changes  button (depending on your version of Trainz) in the rule properties window
