Algodoo

Overall the scene is very well laid out and the interactions between the moving components are about as smooth as they can be with Algodoo. Excellent work!

Thanks.

By the way, you can link the knob handles with script rather than those hidden sliding bars that you used to tie the two knobs together. Here's what I did that works well:

In the upper knob handle (master):
PostStep = (e)=>{
scene.my.handlePos = pos
}

In the lower knob handle (slave):
PostStep = (e)=>{
pos = [scene.my.handlePos(0), pos(1)]
}

Of course if you do that to both assemblies you will have to use different variables for each such as scene.my.handlePosA and scene.my.handlePosB.

In general, I don't trust moving glued objects with scripting, but I tried it in this case and it appears to work fine. Thanks.

You're welcome.
