Clamping the spline length

[_Aka_]

Hi,
Here is a method I quickly coded that does what you want. It surely can be enhanced:

Code:

    private static bool RemoveExcess(CurvySpline spline, Vector3 terminatorWorldPosition)
    {
        if (spline.IsInitialized == false)
            return false;

        //The position at which the spline should stop
        Vector3 nearestSplinePointToTerminator;
        float terminatorTf = spline.GetNearestPointTF(terminatorWorldPosition, out nearestSplinePointToTerminator);
        //The index of the last segment to keep, all following segements are removed
        int terminatorSegmentIndex = spline.TFToSegmentIndex(terminatorTf);

        //remove all control points beyong the terminator
        int segmentsCount = spline.Count;
        for (int segmentIndex = segmentsCount - 1; segmentIndex >= terminatorSegmentIndex; segmentIndex--)
            spline.Delete(spline.Segments[segmentIndex].NextControlPoint);

        //Add the last control point
        spline.Add(nearestSplinePointToTerminator);

        return true;
    }
