Hello!

I was wondering about how you would let a dot go around a certain path with actionscript. All tutorials I see are around a circle, but what if a corner shows up? How do you handle that? You can compare this to a dot going around a race track. How would you do that?  
I read that you could do it as a 2D math function, but I can’t find any information about that.

Thank you for any help! 🙂
