Using on-the-fly with objects

[vsully]

One more question:

Vizard seems to have trouble creating on-the-fly objects within the constructor of a class. Whenever I try (simply initializing all the vertex points) in the class, vizard complains that the type 'x' in viz.vertex(x, 0.3,0) must be of type float instead of type ([]).

I'm using code pretty close to what you provided, simply tailored a bit to a class constructor.

Thanks much for all your help.
