Hi!

I have a big problem with the SDK and the documentation to get the following case. I want to create one inport / one outport (Datatype: Real).

The outport should only forward a number of the inport.

I created 3 functions / classes.

Alright. It works. With the line GvSetPortGeData(... I am able to set the Real 3000 from the outport. But how do I get the Real from the inport called inport_LINK.

Thank you very much.

Hi!

Okay, perhaps I simplify my problem.

This code I paste before I return the value to "set" the outport data. But in the Console (see GePrint) the value is 0. The inportvalue with a constant is 25. I only have 1 inport.

Whats my mistake?

Thank you very much

Sorry for asking again, but did nobody got a node to work, that imports a normal Real number?

Thanks a lot

Ok, here is my Calculate function of the node. It outputs the input.

GV_REAL_INPORT and GV_REAL_OUTPORT are from my ressource file

Hi!

I have a short question again.
I tried to get several inports. I am confused a little bit. If I input some vectors via the attributemanager (about the port-inputs) the node add the two vectors.

But when I connect to vectors via two other nodes, the node adds ValueA with the vector (0;0;0)... Does someone find the mistake?

I am confused a lot. Thanks for help..

GvValue* vinport = ports.in_values[0];
     if (!vinport) return FALSE;
     if (!vinport->Calculate(bn, GV_PORT_INPUT_OR_GEDATA, run, calc, 0)) return FALSE;

        GvValue* vinportA = ports.in_values[1];
     if (!vinportA) return FALSE;
     if (!vinportA->Calculate(bn, GV_PORT_INPUT_OR_GEDATA, run, calc, 0)) return FALSE;

     GvPort* ipt = bn->GetInPort(0);
     GeData iptdata = GvGetPortGeData(bn, ipt, run);
     Vector valueA = iptdata.GetVector();

GvPort* iptA = bn->GetInPort(1);
     GeData iptdataA = GvGetPortGeData(bn, iptA, run);
     Vector valueB = iptdataA.GetVector();

     Vector valueC;
