[x3d-public] X3DJSAIL Python: setShape() Method not foundonCollidableShapeparent interface, cannot find in returned object. Needcast.

[John Carlson]

Could it be the final on the setDEF?


still puzzled.

Actually, I am bamboozled by these errors.

Note, that we already have this style that works.  Attached.

We need the right style to cast abstract returned objects to concrete objects in python.  See attached example.

processScene.python:
     [exec] Traceback (most recent call last):
     [exec]   File "C:\x3d-code\www.web3d.org\x3d\content\examples\Basic\RigidBodyPhysics\UniversalJointfuture.py", line 73, in <module>
     [exec]     .setDEF("BOX-GEOM-1") \
     [exec] AttributeError: 'org.web3d.x3d.sai.RigidBodyPhysics.X3DNBodyCollida' object has no attribute 'setShape'
     [exec] Result: 1
     [echo] C:\x3d-code\www.web3d.org\x3d\content\examples\Basic\RigidBodyPhysics\UniversalJointfuture.py

We should probably grant a prize to whoever gets the right casting that works in all instances.

My best bet for short term is to fold the setDEF into the object constructor.

What do people think?
