Hi
I have a question about the object-link-port in Xpresso. I added this kind of ports to my node.
Whats the difference between a Link Port and an Object Port? I would like to connect the Object(Link?)-Output-Port of a Polygon Object with my Inport-(Link / Object)-Input-port and edit some points of it.
GeData iptdataA = GvGetPortGeData(bn, iptA, run);
//This is the part which is called in the Calculation Method of my Node.I didn't work with BaseObjects, CDAtom and I have to check their dependencies, yet.
I have no clue
Thanks for help

You have to use the GVGENERALOBJECT description type. Please have a look at the following example code. It's a node with an object input that prints the name of the object, much like the result node.

Hi, works fine
Thank you...Is it correct to use GetTypeName() to differ the several objects (camera, spline, etc..)? After that I could cast it to the object, right?
Thanks

Hi!
Wrote the needed lines to my project. It works with a BaseObject.
But what about the other objects? With GetLink(..) I get a BaseLink2D which hands its members to BaseTag and BaseObject.-->On BaseObject: ...->GetName() (works)
-->On BaseTag: ...->GetName() (doesn't work)!!!! ????The BaseTag is derieved from the BaseList2D. I am confused about it.
Could someone throw a light on my prob? Thx
