Use a variable for a hotlink

Hi,

I'm trying to use a global variable a a part of a hotlink like this:

MAIN:/project/model/ProcessorX>variables/cycletime

To specify the number X of the chosen Processor the user should type a number in a textbox which updates a global variable called recent_processor_number.

And how can I integrate this global variable into the hotlink? I've tried it like this but it didn't work:

concat("MAIN:/project/model/Processor",numtostring(recent_processor_number),"> variables/cycletime")

the command numtostring(recent_processor_number) should deliver the number X of the chosen processor.

Thanks a lot!

Attached is a model that shows how you can link an edit field in a GUI to a global variable. It uses a coldlinkx, but you could also use hotlinkx if you wanted a hot link instead.

Thanks for the code, I used it for a text box to update the global variable.

Now I'm trying the integer value of a global variable (that I can now update from a textbox) for a hotlink from a script window to a chosen node. The global variable like recent_processor_number should be part of the path in the hotlink.

Thanks

You can use a hotlinkx instead of a normal hotlink. Write code in your hotlinkx to return the node you want to point to.

such as:

switch(recent_processor_number)
{
case 1: return node("/Processor1",model());
case 2: return node("/Combiner7",model());
}

or

return node(concat("/Processor",numtostring(recent_processor_number,0,0 )),model());
