Dear Ferdinand,

Thank you so much. I've found it tricky to navigate the API reference. Being able to get a pointer to the object parameter through drag and drop is a game changer for me!!

Dear friends,

I'm wanting to generate a large number of splines to animate their form and shape.

I'd like to do this with code so I have point-level control over all splines.

I have been able to create the tracer object and connect to 3 nulls.

However I can't see how I can set other properties such as the spline Type [Linear, Cubic...] and the Intermediate Points property.

Many thanks
Andy
I'm an artist but can program a little.

def main():
    # Create a MoGraph Tracer object

    tracer = c4d.BaseObject(1018655)

    # Insert the Tracer object into the document
    doc.InsertObject(tracer)

    # Create a cube to trace
    null_1 = c4d.BaseObject(c4d.Onull)
    null_2 = c4d.BaseObject(c4d.Onull)
    null_3 = c4d.BaseObject(c4d.Onull)

    null_1.SetName("pt1");
    null_2.SetName("pt2");
    null_3.SetName("pt3");

    newPos = c4d.Vector(100, 100, 0)
    null_1.SetRelPos(newPos);


    newPos = c4d.Vector(100, 200, 0)
    null_3.SetRelPos(newPos);

    # Insert the cube into the document
    doc.InsertObject(null_1)
    doc.InsertObject(null_2)
    doc.InsertObject(null_3)


    # Create an InExcludeData object and add the null objects to it
    in_ex_data = c4d.InExcludeData()
    in_ex_data.InsertObject(null_1, 1)
    in_ex_data.InsertObject(null_2, 1)
    in_ex_data.InsertObject(null_3, 1)

    tracer[c4d.MGTRACEROBJECT_OBJECTLIST] = in_ex_data

    tracer[c4d.MGTRACEROBJECT_MODE] = c4d.MGTRACEROBJECT_MODE_LINK


    c4d.EventAdd()

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