Problems with kangaroo solver

[isabelle]

Hey guys,
I have some problems with kangaroo right now. I don’t know what I am doing wrong, but the solver does not work like it should. The points are moving up endlessly, but the “star” stays horizontal and does not create this organic structure. Can someone help me? And can someone maybe tell me how to prevent the structure from moving up endlessly?

Thats what I wanted to do, it’s from this tutorial: http://mkmra2.blogspot.com/2016/11/kangaroo-physics-simulation-for.html?m=1

Thats what my version does
