Getting Distance from a World Point

[zorksox]

Given a Vector3 in world space, I want get the nearest distance along a spline.

Currently I can use GetNearestPointTF to go from Vector3 to TF and  I can convert the TF to a distance. The problem is that the TF value is not consistently spaced along the curve. It appears that distance is consistent so I would like to use that value instead.

I need something like spline.GetNearestPointDistance()

Surely others have had this issue. Is this possible?

Hi
Does this answer your question?
spline.TfToDistance(spline.GetNearestPointTF(...))

Hmmm....that works perfectly. I'm a bit confused why it works. Previously I was using GetNearestPointTF and using that as my From value in a Curvy Generator. The spacing was not consistent, essentially making the From value slightly wrong. I would expect converting a slightly wrong TF value to a distance would result in a slightly wrong distance. Can you explain why this works?

TF is not a value that progresses linearly along a spline. Distance on the other hand does. Modules in the Curvy Generator use values that progress linearly. More details in this video:

I hope this helped.
If and when you feel like it, please leave a review for the asset, that helps a lot.
Have a nice day
