Thank you very much, this works as expected and is easy to understand.
However a complete example of a bouncing ball would be super awesome
since I have trouble to get it work with integralLim_.
My first try was to use object_ from Control.Wire.Prefab.Move but got
stuck very quickly.
I think this would be a good addition to the quickstart tutorial.
