[x3d-public] X3D minutes 11 FEB 2022: , X3D4 Particle Systems component review, adding enabled field to X3DParticleEmitterNode ?

[John Carlson]

Please confirm the validity of the ExplosionEmitter.py (generated) in your
environments.  I have provided the x3d, but you will need to run it through
X3dToPython.xslt, or otherwise use the previously attached file.

ExplosionEmitter.py
  File
"C:\Users\john\X3DJSONLD\src\main\python\net\x3djsonld\Library\Tests\Components\ParticleSystems\ExplosionEmitter.py",
line 113
    WindPhysicsModel(speed=0.5,gustiness=2)
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
SyntaxError: invalid syntax. Perhaps you forgot a comma?

I will take a break to avoid any further confusion on my part.
