Hi
Dedim, I am actually using the onclick/hide solution, and for the coordinates that could be an interesting challenge but as you said, setting all coordinates for every "obstacle" would be time consumer.
Tig, I've checked Sketchy-Physics, it could be a solution but I do not figure out how to integrated it. I will try sketchy-Physics first and dig deeper to see where this will lead.
I thank you both for your time and your experiences.
whish you both a good day.
