One additional question, is there a list or table or something to look up this "GV_DYNAMIC_DATATYPE" relations?
I cannot find anything about his in the documentation ...
Perhaps im just blind ?

The GV data types are documented in the ID_GV_DATA_TYPEs enum.

Hey,
i got another question

Is it also possible to go from an xPresso Node back to the object in the c4d scene the xPresso Node is related to?
For example something like if i have 3 cubes in my scene i can determine with the xpresso node which cube as a BaseObject im working on with the xPresso Node?

Cheers

Yes, retrieving the node's parameter with DescID(GV_OBJECT_OBJECT_ID) as explained in this post.
In your case you would just call GetParameter() instead.

Hey Yannick,

so you meant its done like this:

  
GeData data;  
data.SetBaseList2D(pRefObject); <- (expresso node object?)  
pNode->GetParameter(DescID(GV_OBJECT_OBJECT_ID), data, DESCFLAGS_GET_0);  
pNode.... ? -> Whats here to retrieve the node?

Sorry for asking again but i think documentation is not very helpful here

There is no method "SetBaseList2D" existing - nowhere. I checked documentation and source code and api code.
How can i retrieve the node object when i only get an id from the GetParameter method?

Cheers,
Oukie

SetBaseList2D() is new in R13, SetBaseLink() was used before. But in your case you don't need this method; you just want to get the parameter data. It's used to set the data before calling SetParameter().

GetParameter() returns a state boolean if it succeed or not. The parameter data is assigned to t_data argument.
Here's how to retrieve the node object:

node->GetParameter(DescID(GV_OBJECT_OBJECT_ID), data, DESCFLAGS_GET_0);
BaseLink* link = data.GetBaseLink();
if (link)
    BaseList2D* obj = link->GetLink(doc); // Get node object

Thanks a lot Yannick.
This works like a charm
Ah thats why i like the maxon guys You are so quick and competent.

PS: I think there should be a mailer list that notes you when functions like this changed in the api.

This is listed for each new release in a "API changes" page in the documentation.
