Monotonically increasing segment F
#1
Hello,

   I'm using the SplineController class to navigate a spline with constant speed. While the object is on a specific segment I want to get the local segment F and drive some other system with it and I want the F to move at constant speed between 0 and 1 on the segment. I'm using SplineController.Spline.TFToSegment to get the local F.
   The problem is the sampled local F values form a curve like this, when plotted, instead of a straight line:

   Is there any way to get a monotonically increasing local F?

Thanks

Hello
F isn't necessarly proportional to distance. Please read this for more details
https://curvyeditor.com/documentation/splines/start#units
The API has some convertion methods like CurvySplineSegment.LocalFToDistance

Hello,

Thanks for the reply, Aka. I'm posting a small follow-up in case anyone else needs this.
The solution is:
Code:
float positionOnSegment;
CurvySplineSegment segment = Spline.DistanceToSegment(SplineController.AbsolutePosition, out positionOnSegment);
float percentageOnSegment = positionOnSegment/ segment.Length;
TL;DR convert from absolute distance to percentage

Have a nice day
