how to make "senddelayedmessage" generic ??

Hello

We have a few network nodes (500), connected to each other to form a rail network. We are trying to make a trigger in the network nodes, so that as soon as a transporter exits one link ( a connection between two network nodes), the exiting network node (NN2) send a message back to the previous network node (NN1) making that link available for other transporters.

this is the code we have developed which we have put as an on arrival trigger for NN2.
senddelayedmessage(node("/Bondi Junction",model()),0,current,0,0,0); ( Bondi Junction being NN1)
We would like to know how to make this generic, so that we wont have to edit each and every code with the NN1 name.

Thanks

Please do not use constructs with a name (so node("/Bondi Junction") etc.) this is slow and especially with large models.

You might be able to create a hash table on reset. Simply go through the model (look at the forobject... functions) and make a column with the pointers as numbers to the previous objects and store on a label on the object the row nr of this table.

to store a pointer write something like: settablenum( "HashTable", row, col, tonum( modelobject )

and on the node write a function like

senddelayedmessage( tonode( getlabelnum( current, "RowLabel" ), 0, current, 0, 0, 0); (Even faster would be to use a ranknumber instead of "RowLabel" )

there are other ways for instance write a global function and call that function from every node and pass in the current.

Or something completely different, write on a transporter a list of pointers of the nodes that the transported has passed and everytime it enters a new one send a message to the first of the list and remove that pointer.

I hope that you have some ideas now.

Or send it to outobject(current,fromedge).

If the traveller has been idle at the node, fromedge may be zero so you'd need record it in the arrivaltrigger
