How to use Unity with ROS kinetic?

edit

Thank you for your quick reply. Would you please let me ask one more thing? It is the first time I should use ROS# based on C#. As I've worked Python primarily, have you ever heard or seen the communication through Python between ROS and Unity, not C#? Would it be not feasible to do?

Based on this Unity forum discussion, it's possible but not necessarily easy. Obviously, it depends on your ability and what you're trying to do, but personally, I think it's better to just learn C# as there are so many tutorials specifically for Unity. If it's a simple project, there may already be a how-to. If it's more complicated, trying to do it through an extra interface layer seems like it would just make troubleshooting more difficult. Long-term, it would be easier to develop and make changes in C#, so why not start learning now? BTW, here's the Roll-a-ball tutorial I followed when I started with Unity, but note there's a link to an update in its description. Everyone's different though, so do what's right for you. You can always switch course later, too.
