SOLVED Unable to Modify the Input Port of the Math Node

Hi,

I'm trying to create a math node and modify its corresponding Input[2]. However, it gives me an error TypeError: __setitem__ got unexpected type 'float' I tried with an integer but it also gives me an error.

Is there a way around this?
Thank you for looking at the problem.

You can see the code here:

import c4d

# Main function
def main():
    cube = c4d.BaseObject(c4d.Ocube)
    doc.InsertObject(cube)
    expresso = cube.MakeTag((c4d.Texpresso))
    nodemaster = expresso.GetNodeMaster()
    
    math_node = nodemaster.CreateNode(nodemaster.GetRoot(), c4d.ID_OPERATOR_MATH, None, x=0, y=0)
    
    # This line works
    math_node[c4d.GV_MATH_FUNCTION_ID] = 2 
    
    # This line does not work. The '[2000,1001]' was retrieved by dragging the Input[2] to the console. 
    math_node[2000,1001] = -1.0   
  
    c4d.EventAdd()


# Execute main()
if __name__=='__main__':
    main()

Hello,

the "input" parameters are dynamically created parameters. So it appears they need a little bit more love.

It seems to work using the fully qualified DescID and SetParamter().

subContainerID = c4d.DescLevel(2000, c4d.DTYPE_SUBCONTAINER, c4d.ID_OPERATOR_MATH)
inputID = c4d.DescLevel(1001, c4d.DTYPE_REAL, c4d.ID_OPERATOR_MATH);
paramID = c4d.DescID(subContainerID, inputID)
math_node.SetParameter(paramID, 99.9, c4d.DESCFLAGS_SET_0)

best wishes,
Sebastian

RE: appears they need a little bit more love.
Thanks for the clarification. The code works as expected!
