I was hoping someone could point me to a list of all of the Xpresso Node Port ID's.
I am currently writing a script that creates an Xpresso tag on a cube, and then creates a node, of the cube, on the Xpresso graph view. I would like to access the Object Properties > Size.Y port. I can not figure out what the ID for that port. I have tried guessing "c4d.ID_BASEOBJECT_OBJECTPROPERTIES_SIZE_Y", but that does not seem to work.
Any ideas?
Thanks

I think you'll have to use DescID for this.
The kind of code only a mother (or a C++ user) could love.#This example creates an xpresso node with positionX & scaleY output ports #Make sure you have an xpresso tag selected before executing it import c4d def main() : #Get the node master of selected xpresso tag...Make sure you have the xpresso tag selected first! nm = doc.GetActiveTag().GetNodeMaster() #Create the object's xpresso node node = nm.CreateNode(nm.GetRoot(), c4d.ID_OPERATOR_OBJECT,insert=None, x=200, y=200) #Using DescID... Combine the POSITION option, with the VECTOR option. And then assign them to a variable("posX") #Using DescID... Combine the SCALE option, with the VECTOR option.

Thanks for the reply ScottA. I've tried using the code you provided.
#Using DescID... Combine the POSITION option, with the VECTOR option. And then assign them to a variable("posX") #Using DescID... Combine the SCALE option, with the VECTOR option. And then assign them to a variable("scaleY") posX = c4d.DescID(c4d.DescLevel(c4d.ID_BASEOBJECT_ABS_POSITION), c4d.DescLevel(c4d.VECTOR_X)); scaleY = c4d.DescID(c4d.DescLevel(c4d.ID_BASEOBJECT_ABS_SCALE), c4d.DescLevel(c4d.VECTOR_Y)); #Add the position.x output port to the object node using the stuff we have in memory #Add the scale.y output port to the object node using the stuff we have in memory node.AddPort(c4d.GV_PORT_OUTPUT, posX) node.AddPort(c4d.GV_PORT_OUTPUT, scaleY)
It works, (it creates Transformed Position .X and Transformed Scale .Y ports) but it doesn't create the port I was hoping to gain access to (Object Properties > Size > Size.Y) Is it just not possible to create this port automatically?

Finally figured it out.
This code:
node1out = node1.AddPort(c4d.GV_PORT_OUTPUT, (1100, 1001))Will add Size.Y output port.
I was able to figure out the numbers by typing "print(PRIM_CUBE_LEN, VECTOR_Y)" in the console window.
However, now the xpresso node with Size.Y is yellow.

It's yellow because you are telling the node to output the size of something. But it doesn't have any inputs to look at to know what it is you want to change the size of.
It's considered better practices to use the text based ID's whenever you can:
node1out = node.AddPort(c4d.GV_PORT_OUTPUT, (PRIM_CUBE_LEN, VECTOR_Y))-ScottA

Shouldn't the Size.Y be referencing the cube?
The goal of this script is to create a cube inside of a null object. In Xpresso, I want to multiply the Size.Y of the cube by 0.5 and use the result as the Position.Y of the cube.
If I do this manually, everything works fine.
Here is my code.
import c4d
def main() :
null = c4d.BaseObject(c4d.Onull)
doc.InsertObject(null)cube = c4d.BaseObject(c4d.Ocube)
doc.InsertObject(cube,null)xtag = c4d.BaseTag(c4d.Texpresso)
null.InsertTag(xtag)nodemaster = xtag.GetNodeMaster()
print nodemaster.GetOwner().GetName()node1 = nodemaster.CreateNode(nodemaster.GetRoot(),c4d.ID_OPERATOR_OBJECT,None,100,100)
node1[c4d.GV_OBJECT_OBJECT_ID] = cubenode1out = node1.AddPort(c4d.GV_PORT_OUTPUT, (c4d.PRIM_CUBE_LEN, c4d.VECTOR_Y))
print node1.GetOperatorContainer()[c4d.GV_OBJECT_OBJECT_ID].GetName()c4d.EventAdd()
if __name__=='__main__':

Try this line of code without the extra parenthesis:
node1out = node1.AddPort(c4d.GV_PORT_OUTPUT, c4d.PRIM_CUBE_LEN, c4d.VECTOR_Y)

Oops.
Scratch that. I just noticed that doing that removes the .Y from the node.I'm not sure why the xpresso node isn't working properly when the Size.Y port is added.
There must be some other missing step needed to tell C4D to update the changes.
I'm afraid I'm out of ideas.-ScottA

Yeah, it doesn't make sense. When I try to do the same thing with Relative Position.Y the node works fine.

Looks to be a bug
I found that you can side step this by using a "real to vector" node.
So rather than trying to get at the sub component right away you get the entire vector package.
examples are best.import c4d from c4d import gui #Welcome to the world of Python def main() : xtrude = c4d.BaseObject(5116) xtag = c4d.BaseTag(1001149) doc.InsertObject(xtrude) xtrude.InsertTag(xtag) gv = xtag.GetNodeMaster() xtrude_node = gv.CreateNode(parent = gv.GetRoot(),id = c4d.ID_OPERATOR_OBJECT ) xtrude_node[c4d.GV_OBJECT_OBJECT_ID] = xtrude mov = xtrude_node.AddPort(c4d.GV_PORT_INPUT, [c4d.EXTRUDEOBJECT_MOVE])#(c4d.EXTRUDEOBJECT_MOVE,c4d.VECTOR_Y)) ####report_bug r2v = gv.CreateNode(parent = gv.GetRoot(),id = c4d.ID_OPERATOR_REAL2VECT ) r2v_x_in = r2v[c4d.GV_REAL2VECT_INPUT_X] r2v_out = r2v.GetOutPorts()[0] r2v_out.Connect(mov) c4d.EventAdd() if __name__=='__main__': main()
