I would like to create a path for characters to walk along.  Easy enough - I can do that!
Now I want to have another character, hopefully using the same path, follow behind the first character but at a faster pace.  When they get to the same point, the faster character has to go around, then get back on the path.
Then I want to have a third character walk towards the first one, and when they meet, they each dodge to their right a bit to pass, then continue on the path.
I am unsure how to look up how to do this because searching for "path" returns lots of irrelevant results.
So, what is this called?  Is it possible? or does each character have to have their own path?  Is it something I can program in python?  (I haven't started learning python yet)
Thank you!
