Show trajectory..?

I would like to show both the trajectory of the incoming sphere(including changes based on reflections), and the trajectory of the sphere it will hit? Should I be dusting off my old maths books, or is there a simple way to do this in Phaser?

One idea I had was to trace the points of a dummy shot as the player angles their shot. I think this might work, although I’m still open to other ideas.

[edit] I tried this idea it works pretty well :wink:
