It doesn't open on V8, presumably needs an update?

Hello @simonjackson1964, do you have this version:

Kind regards

Yes @simonjackson1964 8.5.2.0 beta is needed.  Sorry.

But it is a new feature. Could be interesting if you want to send the train to another portal via event management. ( EV )

Just the code as preview :

Kind regards, Herman

I see, this does look interesting.

So for example, I could have a start portal with a V-depot feeding road vehicles to it, a list of end portals, indexed via a random number generator, and have the road vehicles go to a randomly selected entry-point on the layout?

I had (at version 7) a layout that had almost every variant of almost every road vehicle (except a few I didn't like) loaded in a V-depot, and they would pick a random route down a hidden road with lots of junctions, to arrive at the portal that linked to the entrance point. But this new thing would be a lot more efficient.

Sadly a computer failure means I no longer have that layout. And yes I know I should have backed them up. Lesson learned.

Sorry for the double post... Could this feature be expanded to allow the connection property on other objects to be accessed via EV? So for example,

In the above situation the connection between the main and advance signal could be changed depending on the point setting?

you can already use the EV to respond to a changing main signal and set the advance signal accordingly, taking the current switch setting into account.
Similar effort, just a different approach.

Does that help?

 

[simonjackson1964]

I know, but if the junction wasn't there, I'd just connect the two signals together, set the advance signal to "Do Nothing" on the route it's actually in, and leave it at that.

Is Lua an option for you, @simonjackson1964?

The following code does exactly what you were asking:

if track.state == 0 then
  $("Formvorsignal 1").connection = $("Formsignal 1")
else
  $("Formvorsignal 1").connection = $("Formsignal 1#2")
end

The property "connection" is the type of link that lets one signal mimik the other.
This property became available with version 8 of the software

The "track.state" in my example is the condition of a switch point, which I used to trigger the event.

Lua is something I am learning slowly and piecemeal. As with any programming language, the trick lies in knowing what goes where, and what you can and can't do with a function, operation, and property, as well as knowing what of the aforementioned building blocks are available!

When I was in my 20s I learned a version of COBOL for my work, and there was a massive book in the office with all the various non-standard functions that could be called to do different things.

In my 30s I tried to learn Delphi, and in my 40s, Visual C++. I mastered the syntax and the basic principles of both languages easily. What I didn't have was that book with all the available function calls and what they did!

I might see if I can find a book on Lua, because it would be handy to know it.

But yes, I can see that function, could easily be modified from a standard Event "When Switch Position Changes"... Thanks. If I ever find myself needing it, I will have totally forgotten this post!
