SplineMesh VS Path-Creator

I would suggest to search Github as well. A 5 second search turned up a good handful. One of which looks useful: https://github.com/methusalah/SplineMesh

There's a ton of procedural spline mesh generators. https://github.com/methusalah/SplineMesh in particular is very good.

Is SplineMesh the tool that you're using?

A keyword you may want to look into is Spline. A spline will help you define a curved line, which you should then be able to move the ball over. (If you don't want to code it yourself, maybe SplineMesh can help you out)

it's open source. you can pick it apart and use it as a starting point, adapting pieces of it to do what you need it to do. or you can just use a simpler bezier curve lib and add the dragging mechanics yourself. This lib seems to build road like meshes easily.

If you want to avoid using physics, you could create the path you want the boomerang to take, by using Bézier Path Creator

Lemme tell you, this camera system is a huge pain in the ass to work with. Basically the camera moves along a bezier path towards the nearest point to the player. It's always looking at the player, plus an offset. The camera position also has an offset on it, which is how you get certain angles. There are hidden triggers that switch to different paths when the perspective needs to change (behind the player vs beside the player, ect). There's also override zones and a few custom camera types. It's mostly automatic but annoying to make the path!

I'm using Sebastian Lague's spline tool: https://github.com/SebLague/Path-Creator

Here a free package so you can use that: https://assetstore.unity.com/packages/tools/utilities/b-zier-path-creator-136082

Though, this free asset from Sebastian Lague could get you started. It can move an object (in your case, the camera) at constant speed along a path. If you want the speed to vary along the path, someone will need to code that. I extended his script to increase/reduce the speed of the object depending on the slope of the curve. It worked fine for my purpose.

Dreamteck Splines 2

As I mentioned in my previous update, I've gone back and modified the movement script. This time, I'm using a preexisting asset and just modified a few parts. It's a little bloated (containing 3D features which I don't need), so I'll probably work on only including the implementations that I actually need.

I would consider changing the approach altogether. If you use a spline tool (such as Curvy or Bézier Path Creator), you can then use the curve to procedurally create the model and have it conform to any surface.

We already used [Path Creator by Sebastian Lague](https://assetstore.unity.com/packages/tools/utilities/b-zier-path-creator-136082) (it's FREE!) in our previous project and it comes with an example that extrudes a mesh along a path. It was easy to adapt Sebastian's example to our needs.
