How to make particles/animated lines follow a dynamic curve?

Most of the question is in the title. I’m looking into making a lobbing sort of weapon, and want to make a dotted line or particles flowing in a line that arcs up and the finishes on the spot on the ground where my mouse is and cleanly follows the mouse while aiming.
I think i can make a path2D and adjust a curve to go from my player to the spot, and I could presumably instantiate a path to unbind it from my player to shoot the actual projectile, but I don’t know how to make an actual cohesive animated and dynamic line vs just sending something along the path. I also am unsure how I could do something with particles following a specific curve either.

Thanks for any help you can provide ^^

You can calculate a new curve on each change of your mouse’s position - all you need is 2 points: the origin point (which would be your gun) and the end point (which would be the mouse), with the “out” or “in” parameters set up, depending on what you want your curve to look like, see example below:
