How to get the objects on the edge between to networknode

For example, I have two networknodes, and these two networknodes are connected by an edge. There will be some transporters move along the edge. The problem is, how can I get the objects moving on the edge? Is there some function like getObjectsOnEdge(node num, node num)?

Thank you very much for your help!

you can get it from onarrive trigger
treenode traveler = parnode(1);

so you can setlabelnum(current,"traveler ",tonum(traveler ));
and then you get it.


perhaps jason can provide more easy way.

First you need to find the 'active travelers' node for an edge which is :
treenode activetravelers= gettablecell(connectionsout(<netnode>),<edgenum>,PORT_ACTIVE));

So then content(activetravelers) tells you how many are travelling along the edge.

If you then choose <traveler number> to be a valid number up to the content, the traveler can be found with:
ownerobject(tonode(get(up(tonode(get(rank(rank(activetravelers,<traveler number>),2)))))))

Not less complex, but can be used anywhere with less setting up.
