Hi,
I tried to get the inport data of my plugin node but I can only retrieve the data of the first port. The second one is NULL. I tried two ways:

    
    
    GvPort* ipt = bn->GetInPort(1);  
       GeData iptdata = GvGetPortGeData(bn, ipt, run);  
       Vector pos = iptdata.GetVector();  
    
    
    
    
       GvPort* inport = vinport->GetPort();   
       GeData inportdata = GvGetPortGeData(bn, inport, run);  
       Vector normale = inportdata.GetVector();

the second one does give me the data of the first inport correctly. The first one doesn´t give me the data, though the port is correct and I can also get the name of the port. How can I get the data of several ports then?
Thanks
Samir

Hi,


I am already doing this.


static LONG input_ids[] = { NORMAL,0,LEAVECOUNT,1}; // Use this for the input ports!  
enum { INPORT_LINK_INDEX };


and then the same procedure as shown in your example above.


here is some code then in my calculate method

    
    
    Bool Calculate(GvNode *bn, GvPort *port, GvRun *run, GvCalc *calc)    
      {      
         
       if (!port) return FALSE;          
       BaseContainer *data = bn->GetOpContainerInstance();    if (!data) return FALSE;  
       LONG offsetseed = data->GetLong(OFFSET_SEED);      
       LONG offset = data->GetLong(OFFSET);  
         
       Random rnd;  
       rnd.Init(offsetseed);
    
    
       GvValue* vinport = ports.in_values[INPORT_LINK_INDEX];    if (!vinport) return FALSE;      
       if (!vinport->Calculate(bn, GV_PORT_INPUT_OR_GEDATA, run, calc, 0)) return FALSE;   
         
       /*LONG portcnt = bn->GetInPortCount();  
       GvPort* ipt = bn->GetInPort(1);  
       GeData iptdata = GvGetPortGeData(bn, ipt, run);  
       Vector pos = iptdata.GetVector();  */
    
    
       GvPort* inport = vinport->GetPort();   
       GeData inportdata = GvGetPortGeData(bn, inport, run);  
       Vector normale = inportdata.GetVector();  
    
    
    [...]

The problem is that I cannot get the second port with vinport->GetPort().


This only returns the first inport. GetPort() should take a SubID parameter for the inport afaik


but that doesn´t work either.


Am I missing something? :\

Uhm, input_ids is supposed to be zero terminated. So you should have:

    
    
    static LONG input_ids[] = { NORMAL,LEAVECOUNT,0};   
    enum { INPORT_NORMAL_INDEX, INPORT_LEAVECOUNT_INDEX };

Then you repeat the whole ports.in_values part for each port.
