#89 x3d.py issue, PixelTexture has no len()

[John W Carlson]

This might be my serializer, trying to repeat with X3dToPython.xslt

python ../python/net/coderextreme/data/MultiTextureDesignPattern.py

My copy of this file has a problem, apparently unrelated to Comment?   Here's the online source.  I will try to duplicate with online source:

Online Python cfhecks out

$ python ~/MultiTextureDesignPattern.py

Self-test diagnostics for MultiTextureDesignPattern.py:

Python-to-XML X3D 3.3 schema validation test of XML output complete

python MultiTextureDesignPattern.py load and self-test diagnostics complete.

Copying sourceforge version to local working directory.

[ no output ]

Apparently, the issue is with my Python. I am not sure what you want to do, so I am attaching my python derived from sourceforge X3D.

Here's the X3D file I am using:

[John W Carlson]

Again, no issue with Archive or x3d.py that I know of. I will try to troubleshoot

[John W Carlson]

texture is an MFNode. I don't know what happens if self.texture is None.

This appears to be the problem in my PythonSerializer.js. I am not treating texture as an MFNode!

Appearance30.material = Material31
MultiTexture32 = x3d.MultiTexture()
MultiTexture32.alpha = 0.8
MultiTexture32.color = [0.9,1,0.2]
MultiTexture32.function = ["COMPLEMENT","ALPHAREPLICATE"]
MultiTexture32.mode = ["MODULATE","REPLACE","BLENDDIFFUSEALPHA"]
MultiTexture32.source = ["DIFFUSE","SPECULAR","FACTOR"]
"""add multiple texture nodes here"""^M
ImageTexture33 = x3d.ImageTexture()

MultiTexture32.texture = ImageTexture33
MovieTexture34 = x3d.MovieTexture()

MultiTexture32.texture = MovieTexture34
PixelTexture35 = x3d.PixelTexture()

MultiTexture32.texture = PixelTexture35

Unit test succeeded, performing wider test.
