Simulation of a rolling or flying coin / Kangaroo

I am trying to simulate a 1€ coin which is flying or rolling.
Any tips or suggestions on how to do this?
Is grasshopper and kangaroo all I need or are there more plugins required?

EDIT: Looks like I found something.

I’m pretty new to this platform, any idea where to look for this example?

Kind regards,
Jonas

Hi @Jonas_Tretter ,

The examples from here (particularly the 2d one) might be useful:

Simulating a marble ramp

Hi @reginald.raye The goal from here should be useful Here’s an example marblerun.3dm (4.0 MB) marblerun.gh (16.1 KB) (and here if you want to include multiple balls with collisions between them marblerun_multiball.gh (101.3 KB) ) You should be able to just replace the surface inputs with a new ramp design. Only include the stuff the ball will actually touch to avoid extra calculation. This doesn’t consider surface friction or angular momentum, and I’m sure you’d need to make ph…

Hello @DanielPiker,

thank you for pointing out that there is a similar topic.
I will have a look at the examples as soon as I get a chance.
I’ll keep you posted, if I may.
