How-to create a session

The Trainz session concept is very powerful. The very name eponymously refers to a Session of Driving. Unfortunately, all most people use it for is adding consists to a route, assigning some AI orders, and setting a few basic start-up settings for the session in the default rules.

This document is a quick introduction to sessions aimed at getting people to think beyond this most basic level of session, and to take more advantage of the power and flexibility of the session concept.

It assumes you are familiar with Driver and basic Surveyor usage including placing scenery and trains. If this doesn't sound like you, then you may need a more basic introduction to Trainz Driver and Surveyor first.

The smartest way to gain some familiarity with a session rules organization and programming is to take a look under the hood of a well written Driver Session that piques your interest. Perhaps there's a passenger train schedule keeping tutorial you can't quite do well enough scoring on when running it, or a well prompted session with a variety of activities, like the venerable Highland Valley Industries (Tutorial 5, TRS-2004—TS2010 releases) route. This older tutorial has a lot to commend it, and is easy to automate the driver activity down to the task of having the AI Driver switch one train to the other. Driving the second train loco, will teach the trainee how to insert driver commands on the fly to complete the task. It's a fun route, and a Trainz Classic Road. We also introduce a little bit of data management with Content Manager operations to download the small route and it's session. This should enhance your interest in Trainz for the DLS is the best asset we all own a part of!

  • DLS searchable web interface - This site let's you browse like many online stores, with CM being inactive. You can fill a shopping cart, then tell it to download, and it will launch CMP or CM for you.
  • Route:
  • Session:

Your first interactive session

It's time to create your first session.

In the routes menu, find the route 'Springfield Industrial District' (you may have to unselect 'show only favorite routes'). This example uses this route because it's small, and everyone has a copy. Show the sessions, and then click 'new session'.

Place a CHN ND5-1 on one of the turntable tracks, and a CHN G70K tanker in the yard next to the turntable.

Setting the initial startup options

Now open the 'Edit Session' dialog on the main menu. Change the session name and type something in for the description.

You should have something that looks roughly like this:

Session-tutorial-1.jpg

If you are using TS2010, remove the 'ConsistDataHandler' and 'QuickDrive' rules. Nice though they are, we don't want the player of this session to be able to arbitrarily create new vehicles. To delete the rule, click on it to select it, and then click the 'Delete' button.

Note: If you are using TS12 or Trainz Simulator Mac, you won't have 'startup options' - 'QuickDrive' has taken over this role. So instead of deleting those two rules, edit the 'QuickDrive' rule (highlight it and click the 'Edit' button), and tick the "Gameplay Session" option in the QuickDrive options. Save the changes.

Adding a displayed score

Add the Display Custom HUD Rule - click 'add', find 'Display Custom HUD' in the list, select it, and click the tick button.

Add a Variable Modify Rule. Once you've added this, click the 'Edit' button, and you can set the rule properties. Anything you can click on is underlined. Click on 'Add', and set this to 'Change'. Also set the number to '0'. It should look like this:

Session-tutorial-2.jpg

Confirm these changes by clicking the tick button on the 'Properties' dialog.

Add a Variable Show Rule.

Checking the user makes a train correctly

Add a Consist Check Rule. Select 'Complete whenever a train matching the description exists'. This opens up several more options. Under 'Specific Vehicles', click the plus, and add our ND5. Repeat this and add the G70K as well. Also tick 'Enforce strict exclusive checking'. It should look like this:

Session-tutorial-3.jpg

'Enforce strict exclusive checking' will make the consist check rule check the consist more thoroughly - so if someone picks up too many vehicles in the yard, it won't trigger.

Confirm these changes by clicking the tick button on the 'Properties' dialog.

Finally, Add a 'Variable Modify' rule at the bottom, under 'Consist Check'. We will click the right arrow button once to indent the rule one level to the right.

This means this rule will not take effect immediately, but will be triggered by the 'Consist Check' rule, when the consist exists.

Now tick the 'Edit Session' dialog.

Driving your first session

Let's try this out in Driver now.

Click on the Driver button next to the main menu. Save the session. (If it asks to save the map, you've done something wrong - did you place the trains in the wrong layer?)

In Driver, you should see the 'Custom HUD' panel, and in it, an extra field labelled 'Score'. It should be zero. Take the ND5 over to the G70K tanker, and couple up to it. If the rules are set up right, 'Score' should change to '1'.

Session-tutorial-4.jpg

Adding a pickup task at an industry

Okay, let's take this a stage further. Go back to surveyor, and set the current layer to the session layer in the layers tab.

Configuring an industry

Configure 'Palmer Chemicals', by clicking on the industry track (between the two arrows) with the question mark icon from the 'scenery' tab. This is a 'multiple industry new' track. As this is a new session, it won't have any configuration yet - so we'll need to add some. See HowTo/Configure an Interactive Industry for details.

Checking the user uses the industry

Go back to the 'Edit Session' dialog. At the bottom, add a 'Resource Check' rule. Edit the resource check rule.

Pick the 'Watch Vehicle Queue' option. Within this, set 'CHN G70K Tanker' as the target object. Set the queue to be 'liquid' (there should be only one option). Set the product to be Aviation Fuel. Set the amount to be '72040' (you can actually type in '99999' and it'll autocorrect to the maximum size of the queue if it's larger than what the queue can hold). Ensure 'Complete when the designated queue equals or exceeds required amount' is set. It should look like this:

Session-tutorial-5.jpg

Tick the Properties dialog.

Now add a 'Variable Modify' rule below the Resource Check Rule, configure it to add one to the variable 'score', and indent it one step to the right. Your session rules should look like this:

Session-tutorial-6.jpg

Testing the extended session

Now let's try this out in Driver. Couple the ND5 to the tanker as before. The score should update to 1 when you do this. Now take the wagon up the hill to Palmer Chemicals.

Stop the wagon next to the three pink tanks, and wait for it to load. Once it is loaded, the score should update to 2.

Session-tutorial-7.jpg

Adding a delivery task at an industry

And another stage. Go back to surveyor, and reselect the session layer.

Go to the airport, and in it's properties, set it's Aviation Fuel queue to start at Zero and consume Zero.

Now in 'Edit Session', add another 'Resource Check' rule to the bottom of the list. Configure this one to watch an industry queue on 'Local Airport'. There will be several queues here - you want 'av_in_q', with product 'Aviation Fuel'. We're going to watch for 144000 units, and complete when the queue equals or exceeds the required amount.

It should look like this:

Session-tutorial-8.jpg

Underneath and indented beyond this, we're going to need another Variable Modify rule.

When we test this in Driver, we'll need to fill the tanker twice - and deliver two loads. Only at the second load will the score go to 3.

Hints and Tips

Some background information you may find useful.

Layers

TS2010 introduced the concept of layers to Trainz, and when working on a session, you will need to use them. The key thing is that this allows you to add most types of Trainz assets to the session, which previously could only be used in a route. As well as the usual Traincars, this can be scenery objects, trackside objects, even splines.

A good tip is to lock the route layer(s). This will help prevent accidental editing of the route layers.

Pay particular attention to layers if you use the 'quicklaunch' feature to launch Driver direct from Surveyor and return to Surveyor afterwards. The layer you had selected before probably won't still be selected afterwards, so you'll need to check it every time you return from Driver.

'Base session' assets

Some routes come with a 'base session'. This generally has pre-configured settings for industries and other scripted assets in it. You may find, should your chosen map depend heavily on multiple industry assets or other similar scripted content, that you may need to base your session on a 'base session' asset, rather than creating a new session.

In this case, the default rules list may differ - as it may have been created in a different version of Trainz, or the route creator may have decided to change a few things. Feel free to add any missing rules you want, or remove extras you don't.

Default rules

In the 'Edit Session' dialog in TS2010, we have six rules by default.

TS12 and Trainz Simulator Mac does not have 'Startup Options' - 'QuickDrive' now performs that role.

As a general rule, for a pre-planned interactive session, you probably don't want to permit the human driver to issue AI orders, or to be able to use the features of QuickDrive.

However, you probably want to be able to issue AI orders to background AI traffic while making the session, and you'll certainly need to fix those orders later when it turns out they don't quite do what you wanted them to. If you turn them off now, you'll have to turn them back on again when doing these operations - so my advice would be to only turn them off (by unticking them all) in 'Driver Commands' at the end of the creation process, once the session is finished. It'll get too annoying to keep turning them on and off when you need to fix problems with the background AI otherwise.

With TS2010, QuickDrive will unfortunately have to be removed from the rules list. It'd be way too easy for people to cheat using it.

With TS12 and Trainz Mac, it is possible to disable the advanced features of quickdrive, but still use it's better Cab/DCC mode selection screen - simply tick the 'Gameplay Session' checkbox in the QuickDrive options. This will deny the player access to the parts of QuickDrive which would cause problems in an interactive session.
