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

Sat Feb 1 13:35:44 PST 2025

I'm trying very hard to look at this, but I'm not seeing the animation
reset when one turns an animation off.  Perhaps I should try X3DOM?

https://create3000.github.io/x_ite/playground/?url=https://gist.githubusercontent.com/andreasplesch/6fd2fd0b0f745b3549b74150b7752d89/raw/c02637b602f9241c9ea73b5ad859ab330c071e25/toggleReset.x3d

Trying to compare with:
https://andreasplesch.github.io/Library/Viewer/index.html?url=https://gist.githubusercontent.com/andreasplesch/6fd2fd0b0f745b3549b74150b7752d89/raw/c02637b602f9241c9ea73b5ad859ab330c071e25/toggleReset.x3d

If I click multiple checkboxes, AFAICT, the whole animation doesn't reset.
I want ALL animations to reset when a button is pressed in, and when any
button is unpressed.

This is a better link for mine:

https://create3000.github.io/x_ite/playground/?url=https://raw.githubusercontent.com/coderextreme/ci2had/refs/heads/main/resources/CleanedYouClocks.x3d

So probably there needs to be a global start/stop time for all enabled
TimeSensors?

I see you have two ProtoDeclares and I only have one.  I might be able to
do something like that.

Hmm!
