[x3d-public] Fwd: Turning on and off simultaneous animations individually

[John Carlson]

Michalis, here’s a different approach I took, and hit a brick wall with all
browsers.

I did provide a simple initializer, which didn’t appear to change anything.

Indeed, moving the TimeSensor  USE to a fieldValue makes Castle report this:

castle-model-converter: Warning: X3D: Route destination node name "clock"
not found
castle-model-converter: Warning: X3D: Route destination node name "clock"
not found
castle-model-converter: Warning: X3D: Route destination node name "clock"
not found


Seems like I've made a full circle.  Now I can't get anything to work.

So option B) sounds really good, and I'll just recommend Sunrize, or do
scripting.

What I can try to do is provide an initializer value to clock in
ProtoInterface.

see attachment.
