Adding a controller to HoopSnake

Hi,

I'm trying to simulate a condition where a shape grows randomly. I tried using hoopSnake to achieve the overall look which was a success. Now I'm trying to add more control to the system. I wanna avoid intersections in my geometries. Having said that I was trying to add another loop to check if the added element has any intersection with system itself, and if its "True" try to run the loop again with another seed ("Seed" in random component). I would be pleased if any of you would help me with this situation.
