Scenarios/Sessions?

G'Day All, this may seem a silly question but what, basically, is the difference between a Scenario and a Session.

Hi,

A session is a series of driver instructions (created in Surveyor) - you can edit all the driver instructions as the session runs...
It does require all the drivers/lcocmotives/consists to be present all the time....

A scenario is similar, but can be created so that the player is unable to edit any actions, i.e. must follow the planned actions by the creator.
it's also quite possible to create consists (at a trackmark) and remove them as required, so the load on the computer is less.
It is also possible to control all the points and signals in the scenario.

Sessions are created (as above) in Surveyor - for Scenarios, the easiest thing is to use SCS2006 (see Trainz Pro Routes website) - this works with 2009 as well (and possibly with 2010 - I've not tested it!)

Just to add to Colin's execellent description of a session and a scenario.

Yes SCS2006 will work with 2010 also.

In my opinion sessions are run by rules which some one else has made and uploaded to trianz so you don't have as much control of the session as you do in a scenario. Because a scenario using SCS 2006, as Colin says, gives you total contol over what happens

But technicality speaking a scenario written using SCS2006 is a 1 rule session and a true scenario is written in Trainzscript and is used by UTC and 2004.

Hope I didn't confuse anyone. If I did just go back to Colin's explanation.

Not quite, but it's a very common misconception. In fact it is possible to write a totally open-ended scenario. It's also possible to write a scenario in which there is a goal, but it's up to the player how to achieve it - for example, shunting puzzles.

The difference between rules and scenarios is the method of creation. Sessions are created by using rules as building blocks, which gets very complicated for anything the least bit complicated, and impossible if there is no suitable rule for what you want to do unless you know how to create a new rule. Scenarios are normally written in a C-like programming language called GameScript. However, the excellent SCS allows rules which behave like Scenarios to be created by non-programmers. The Razorback development system allows us to write TRS2004 scenarios using GameScript and then also makes a separate rule version for TRS2006. To add to the confusion, GameScript is also used to write new rules and to script assets such as industries. All this makes my head hurt at times.

G'Day All, well I think I got the idea I guess it is just a matter of playing around and learning by your mistakes.:hehe:
Thanks for the great replies which have certainly cleared up a lot of things.
Where can you get SCS I had a look at Trainz Pro Routes site but could not find it, was probably staring me in the face.:D
I have produced quite a few activities for MSTS I just hope that it is easier in trainz.

Hi Barrie

The SCS2006 rule is available on the DLS. There is also a comprehensive manual available on the DLS which should be downloaded as a dependency of the rule. The learning curve is quite steep but once you get to grips with it you can replicate almost any railway operation. TPR have a forum for SCS2006 (next to bottom on the forums page) and it is worth reading through the topics on there.
