Heh, also a funny feature of your anchor constraints: they do not play well with layouts
and animations. Try the code below (adapted from the example to use the layout and
animation of LRP ) and you will see that the circles keep spinning around, they never
stop. I think it would be better for them to stop ;-)
can't help myself :)

Hehe,
good one :-) https://youtu.be/uo0o8eQWfcI ! :-P
stepping := RTSpringLayoutStepping new
view: v; layout: layout;
afterBlock: [ v canvas camera focusOnCenter].
The problem is that RTSpringLayoutStepping>>view sets in effect the layout on all
elements in the view, which obviously won't work since they'll start competing.
I'm not sure right now how to address it, but try this
stepping := RTSpringLayoutStepping new
view: RTView new; layout: layout;
nodes: es;
afterBlock: [ v canvas camera focusOnCenter].
Sorry, I don’t know enough of the internals to understand what’s going on. The solution is
not a solution for me, because it effectively removes the animation, we only see the the
resulting layout. There is no other solution? Alex, do you have any idea?
Ah right, thanks. I've extracted the class from my
code and I have different removal mechanism...
Please try the latest version, it should be fixed there.
Fixed, thanks!
But now there is a new bug RTAnchorConstraint>>computeExtraDistance that I cannot
reliably reproduce, I only have a stack trace, sorry:
