Hi,

I'm adding some Xpresso nodes to my objectdata plugin.
I have a mathnode and SetParameter(GV_MATH_FUNCTION_ID, GV_MUL_NODE_FUNCTION, DESCFLAGS_SET_0) works perfectly.
However, when I try to use SetParameter(GV_DYNAMIC_DATATYPE, GV_INT, DESCFLAGS_SET_0) it does nothing. Even if I change GV_INT to 15 (the corresponding value) it does nothing.

Does anybody know how to fix this?
Thanks in advance for your help and time!

Hi,

Here is some more code, inside MSG_DESCRIPTION_COMMAND:

  
BaseDocument* doc = ((BaseObject* )node)->GetDocument();  
  if (!doc)  
      return false;  
BaseObject* op = (BaseObject* )node;  
  if (!op)  
      return false;  
ModelingCommandData cdFirstObject;  
cdFirstObject.doc = doc;  
cdFirstObject.op = op;  
if (SendModelingCommand(MCOMMAND_CURRENTSTATETOOBJECT, cdFirstObject))  
{  
  BaseObject* firstObject = static_cast<BaseObject*>(cdFirstObject.result->GetIndex(0));  
  doc->InsertObject(firstObject, nullptr, op);  
  if (firstObject)  
  {  
      XPressoTag* myXPressoTag = static_cast<XPressoTag*>(firstObject->MakeTag(Texpresso, NULL));  
      if (!myXPressoTag)  
          return false;  
      GvNodeMaster* myNodeMaster = myXPressoTag->GetNodeMaster();  
      if (myNodeMaster)  
      {  
          GvNode* mathNode = myNodeMaster->CreateNode(myNodeMaster->GetRoot(), ID_OPERATOR_MATH);  
          if (!mathNode)  
              return false;  
      mathNode->SetParameter(GV_MATH_FUNCTION_ID, GV_MUL_NODE_FUNCTION, DESCFLAGS_SET_0); // Works perfectly  
      mathNode->SetParameter(GV_DYNAMIC_DATATYPE, GV_INT, DESCFLAGS_SET_0); // Doesn't work, even not if I change GV_INT to 15  
      }  
      else  
      {  
          return false;  
      }  
  }  
  else  
  {  
      return false;  
  }  
}  
EventAdd();

I hope this provides you with enough information.

Hi,

It is definately something weird, in my opinion.
I've dragged all the possible data types form the math node inside the console, to check for their int values. Here is what I found:
-COLOR 3
-BOOLE 400006001
-INTEGER 15
-REAL 19
-VECTOR 23
-NORMAL 400006005
-MATRIX 25
-TIME 22

However, if I use those values I can NEVER get an integer or boole.
I've tried to use the values 0-30 inside SetParameter(GV_DYNAMIC_DATATYPE) and here are my results:

0, 1, 2, 4, 5, 6, 8, 9, 10, 11, 12, 13, 14, 16, 17, 18, 19, 20, 21, 24, 26, 27, 28, 29, 30 and 400006001 all give me REAL as result.
3 gives me a COLOR.
7 gives me an empty cycle, and for the values two link fields, I guess, where you can click a button "Open" and then you can select whatever you want on your hard disk, ... even c4d-files.
15 gives me an application error, so C4D just crashes...
22 gives me TIME.
23 gives me VECTOR.
25 gives me MATRIX.
400006005 gives me NORMAL.

As you can see, this raises a big problem, if you want to add an integer-math node.
Thanks in advance for your help and answers!

Hello,

I cannot confirm any problems using the value of 15 or the appropriate constant ID_GV_DATA_TYPE_INTEGER. Also I have no problems setting the value Boole with ID_GV_DATA_TYPE_BOOL.

Can you reproduce the crash using the value of 15?

best wishes,
Sebastian

Hi,

I can reproduce it constantly :s
The next thing I will do is try to reproduce it in an empty project, to see if I still have the problem there.
I will post the result here..

Hi,

I've tried it inside a new project, and there it works fine.
It seems to be failing by code that comes after the setting of the datatype.
If I delete that code, my problem is gone.
But, now, I'm on to the next problem, setting the second input port value.

I've found a great post about how to set a port value: http://kinug.com/c4d/cpp/help/pages/c4d_graphview/doc_GVData699.html
However, if I add the method (GvSetPortGeData) and call it with: GvSetPortGeData(-1, myNode, mySecondInPort, run)); it seems to do nothing.
I have also tried this inside my new project, with the same result.
Before my call to GvSetPortGeData() I have the following code:

  
GvPort* mathFirstInPort = mathNode->GetPort(1000);  
GvPort* mathSecondInPort = mathNode->GetPort(1001);  
GvRun* run = myNodeMaster->GetRun();

which comes after mathNode->SetParameter(GV_DYNAMIC_DATATYPE, ID_GV_DATA_TYPE_INTEGER, DESCFLAGS_SET_0);

If you need more information, just ask me.
Thanks in advance for your help and time!

Hello,

when you debug your code you see that GetRun() returns a nullptr so GvSetPortGeData() cannot work. GvRun is only available during the calculation of Xpresso, so GvSetPortGeData() can only be used inside a custom Xpresso node while it is calculated.

But it seems using the correct DescID it is possible to simply use SetParamter() :

  
const DescID id = DescID(DescLevel(GV_MATH_INPUT,DTYPE_SUBCONTAINER,0),DescLevel(1001,DTYPE_LONG,0));  
mathNode->SetParameter(id, Int32(-1), DESCFLAGS_SET_0);
