[x3d-public] need help with import

[John Carlson]

Note, I only create one symbol per file currently, so no problem with namespace confusion, I hope.

Could I do:

import org.web3d.x3d.jsail.Core.X3DObject.X3DObject as X3D

???

You want 

import classpath
import org.web3d.x3d.jsail.Core.X3DObject as X3D               

X3D0 = X3D.X3D() /



The module error was due to not having the module name prepended to the constructor call, which is the required tradeoff for avoiding the namespace messes of from inporting.   It is the from style importing that creates potential silent namespace overwrite problems.  

I hope this helps. Apologies on the terseness, I'm down with a bug.

I think that Loren suggested import * clouded the namespace too much (did we get the same email?).
 
We could do
 
import X3Dautoclass

Yes this is a Loren question.
 
>From prior email conversation and guidance from Loren, I think a good .py file starts with
 
from X3Dautoclass import *
X3D0 = X3D() \
    .setProfile("Immersive") \
    .setVersion("3.3") \
    # [etc.]
