As a reeeaaally quick example, heres a CAPX.
I'm loading a bunch of positions to an array, including angle, then lerping to them and once there I increment a global variable and update the position.
You could also add in invisible marker sprites with ID's instead of having them in an array.
You could dynamically define the points in the array.
You could just use regular animation.
Any of the above would work
Anyway, heres the capx
