Answer 1

You can do a Frame by Frame animation. You can position the object step by step to create a curve. That will be of limited reuse, but you can do it.

Or you can write your own animation to create a subclass of TweenAnimation that can animate along a curve. If you’re good with math and can understand bezier curves then that might be a straight forward option. Once you have that class you could easily animate across any curved path, but it’s more work.

Here’s some Java code:
