Good (free?) lightweight spline solution

Unity Engine
1

Hi there,

I’ll just ask this now - this has been bothering me a good while:

Are there any free spline solutions available?
or some very lightweight AssetStore asset?

Some features I’m looking for:

  • Spline curve with Hermite or some other type / that doesn’t necessarily need manually placed handles
  • Open and closed shape support
  • Possible to get locations along spline with 0-1 values or similar
  • Possible to have values normalized so that movement is not speeding up depending on segment length
  • Possible to get offset position sideways relative to spline (not so important)
  • Possible to set up direction at knot points (not so important)

So, pretty basic features, mostly such features that would be needed in simple games.

I’ve been looking for some spline solution that could give me basic features that I need, without being too heavy / bloated.

I’d prefer single class file kind of solution, which I could use on different projects, without having to think about being able to include it to project because of some license issue.

I have done very limited spline solution once or twice my self, barely working, but the problem was with normalized speed along spline and I’d rather get some pre-made “battle tested” solution, instead of my “almost there” kind of hack.

I have also checked AssetStore options, there are good looking assets like Dreamteck Splines and Spline Editor, but I think these too might not be best option right now… I’m not looking for UI’s, widgets and custom editors, I guess I’d be more happy with some minimalistic solution.

take a look at this. not sure if it heavy / bloated or not.

Thanks, although I was already aware of it, it’s on my checklist.

I guess I’ll have to plough through github and whatnot then I guess…

BTW: after posting above message, I sort managed to fix speed issue in Hermite curve, by normalizing it to segments, however after this, I’m not working with real curve no more, so not sure if it would be problem (offset, direction along curve).
